EXTRUTEX Straw Counting Machine

Automatic Drinking Straw Counting, Grouping and Discharge

The EXTRUTEX EX-250DS Straw Counting Machine is designed to automatically count, organize and discharge drinking straws in preset quantities. It provides a practical solution for manufacturers that need accurately grouped straws before manual boxing, carton loading, bagging or transfer to downstream packaging equipment. With an adjustable counting range of approximately 5–500 straws per cycle, the machine helps standardize batch quantities and reduce repetitive manual counting.

Designed for straws with diameters from 4 to 12 mm and lengths from 160 to 300 mm, the EX-250DS combines a hopper, dual-direction loading arrangement, counting controls and a discharge conveyor mechanism. Operators can set the required quantity and adjust the running speed through the touchscreen interface, allowing production batches to be changed according to different customer orders.

EXTRUTEX combines Austrian design expertise with manufacturing in Nanjing and Shanghai, China. Our equipment solutions focus on practical industrial engineering, reliable operation and integration into production workflows for international packaging and manufacturing markets.

1. Product Overview

Automatic Counting Instead of Manual Quantity Control

Counting drinking straws manually can require considerable repetitive effort, particularly when production orders involve multiple batch sizes or high daily quantities. Manual counting can also create inconsistencies between batches and slow down subsequent boxing and packaging operations.

The EX-250DS automates the counting and grouping stage. Once the required quantity is entered, the machine processes straws through its feeding and counting arrangement before discharging each counted group. Operators can then collect the groups for carton loading, manual bagging or another compatible downstream operation.

The machine is intended for counting and grouping rather than complete automatic bag sealing. It is therefore particularly suitable for factories that need a dedicated counting station between straw production and final packaging, or as a preparatory stage for a separate packing machine.

Adjustable Counting Quantity

The machine supports preset quantities from approximately 5 to 500 straws per cycle. This range allows manufacturers to prepare small batches for compact packages or larger groups for bulk handling. The required quantity is selected through the touchscreen according to the available machine settings.

Changing the preset count can help a factory handle different order quantities without relying on manual recounting for every batch. For best results, the selected quantity should be checked against a physical sample during setup, particularly when switching to a different straw size or material.

Dual Loading Arrangement

The EX-250DS uses a two-way loading design to support straw feeding into the counting section. The arrangement is intended to improve feeding efficiency and maintain a steady supply of products for counting and grouping.

Stable feeding depends on the consistency of the straws, the loading method and the machine settings. Bent, damaged or irregular products may affect feeding behavior and should be removed or handled according to the production procedure.

Touchscreen Operation

The touchscreen provides an operator interface for setting the target quantity and adjusting the running speed within the machine's supported operating range. This simplifies routine changes between different packaging or boxing requirements.

The supplied machine information identifies Panasonic PLC control. The exact screen layout, alarms, available parameters and control functions should be confirmed against the final machine configuration and supplied documentation.

2. Main Features and Advantages

Flexible Counting Range

The 5–500-piece range makes the EX-250DS suitable for a variety of group sizes. Manufacturers can use the machine to prepare counted quantities for retail packaging, food-service supplies, wholesale orders or other production workflows where batch consistency matters.

Adjustable Operating Speed

The stated operating range is approximately 10–30 counting cycles per minute. The actual number of straws processed per minute depends on the preset group quantity, feeding stability, product dimensions and operating conditions.

Counting cycles per minute and individual straws per minute are different performance measures. For example, a cycle containing 100 straws represents a much larger individual-piece throughput than a cycle containing 10 straws, assuming both operate at the same cycle rate. Production targets should therefore be established using the actual required quantity per cycle.

Consistent Group Preparation

Automated counting supports standardized group quantities before final packaging. This can simplify subsequent boxing, carton preparation and order fulfillment by giving operators a consistent batch to handle.

Reduced Repetitive Manual Work

By automating the counting stage, the machine reduces dependence on repeated manual counting. Operators can concentrate on product inspection, loading, collection and packaging activities rather than counting every straw individually.

Conveyor-Based Discharge

After counting, the grouped straws are discharged through the conveyor mechanism for collection or transfer. The downstream arrangement can be planned around manual boxing, carton loading or a compatible additional packaging machine.

Compact Industrial Integration

With listed dimensions of approximately 3200 × 1600 × 1900 mm, the EX-250DS can be planned as a dedicated station within a straw manufacturing or packaging area. Adequate clearance should be provided for loading, operation, discharge, cleaning and maintenance.

3. How the EX-250DS Works

1. Straw loading: Compatible drinking straws are placed into the machine's loading hopper.
2. Product feeding: The two-way loading arrangement feeds straws toward the counting section.
3. Preset quantity selection: The operator enters the required group quantity through the touchscreen.
4. Automatic counting: The control system manages the counting sequence according to the selected setting and installed machine configuration.
5. Group formation: The required quantity is organized into a counted batch.
6. Discharge: The conveyor mechanism transfers the counted group to the collection point.
7. Downstream packaging: Operators or compatible downstream equipment move the counted groups into boxes, cartons or a subsequent packing process.
8. Repeat cycle: The machine continues counting according to the selected operating settings and production workflow.

Before beginning a production run, operators should verify the target quantity and inspect several completed groups. When product dimensions or materials change, repeat the checks to confirm reliable feeding and counting performance.

4. Technical Specifications

Technical note: Specifications are based on the supplied product information. Confirm the final machine configuration, actual counting performance, electrical connection, available control functions and product compatibility with EXTRUTEX before ordering. Cycle rate does not represent a fixed number of straws per minute because the preset group quantity varies.

5. Compatible Products and Applications

Drinking Straw Manufacturing

The EX-250DS is designed for compatible drinking straws with diameters of 4–12 mm and lengths of 160–300 mm. It can serve as a counting station after straw cutting and finishing, provided that product dimensions and feeding characteristics fall within the supported operating conditions.

Manual Boxing and Carton Loading

Counted groups can be collected for manual placement into paper boxes, cartons or other packaging formats. This is useful for factories that want consistent group quantities while retaining flexibility in their final packaging method.

Wholesale and Bulk Preparation

Wholesale suppliers may need counted batches for larger cartons, distribution packs or order-specific quantities. The adjustable preset count supports different batch requirements, subject to the actual packaging specification.

Food-Service and Beverage Supply

The machine may be used in production workflows supplying straws to cafes, restaurants, catering operations, hotels, beverage outlets and food-service distributors. Final packaging materials and product-contact arrangements should meet the applicable requirements for the intended market.

Integration with Downstream Equipment

Where a factory already uses a separate packing machine, the EX-250DS can be evaluated as an upstream counting and grouping station. Any direct transfer or synchronization arrangement should be confirmed during engineering review because the supplied standard information does not specify a universal automatic interface for every downstream machine.

6. Straw Compatibility and Counting Stability

Reliable counting depends on more than the nominal straw dimensions. Straw straightness, diameter consistency, surface friction, material stiffness and product condition can influence feeding and separation. Consistent incoming product quality helps the machine maintain a stable operating sequence.

Straws should be inspected for deformation, blocked ends, damage or excessive variation before loading. If different materials or product sizes are used, a production trial is recommended to confirm feeding behavior and count accuracy under the intended conditions.

The stated diameter and length ranges are reference specifications. They should not be interpreted as a guarantee that every straw type within those dimensions will perform identically without adjustment or testing.

7. Production Planning and Throughput

The EX-250DS is specified at approximately 10–30 cycles per minute. To estimate individual-straw throughput, multiply the actual cycle rate by the preset number of straws per cycle. This gives a theoretical reference rather than a guaranteed production figure, because loading, discharge, product behavior and operating interruptions can affect the practical rate.

For example, larger batches increase the number of straws handled per cycle, but the actual cycle rate may vary according to product dimensions and machine settings. Before setting a production target, test the machine with the intended straw and quantity combination, then record the observed rate and counting consistency.

Planning should also include the capacity of the downstream boxing or packing operation. If counted groups accumulate faster than operators or downstream equipment can handle them, the complete production workflow may require additional collection space, labor or a revised operating speed.

8. Operation, Cleaning and Maintenance

Before operation, confirm that the hopper and feeding areas are clean, the required quantity has been selected and the discharge area is ready to receive counted groups. Start with a trial batch and verify the result before processing a full order.

• Keep the hopper, loading channels and counting areas free of straw fragments and debris.
• Check feeding behavior when changing straw lengths, diameters or materials.
• Inspect the conveyor and discharge area for obstructions or abnormal product accumulation.
• Verify the selected count after any settings change or machine restart.
• Follow the manufacturer's instructions for cleaning, inspection, lubrication and replacement of wear components.
• Train operators in normal operation, safe shutdown and emergency-stop procedures.
• Isolate electrical energy and any other relevant energy sources before internal cleaning or maintenance.

Preventive maintenance and consistent operating procedures help reduce avoidable downtime and support repeatable counting performance. Refer to the supplied manual for model-specific maintenance intervals and adjustment instructions.

9. Straw Counting Machine vs. Automatic Packing Machine

The EX-250DS is designed to count and group straws. It does not, by itself, perform the complete bag-forming, sealing and cutting process described for an automatic packing machine. Choosing between these equipment types depends on the factory's packaging workflow.

Choose the EX-250DS when the priority is preparing accurate groups for manual boxing, carton loading or another packaging operation. Consider a compatible automatic packing machine when the objective is to combine several packaging steps into one machine. Confirm all required functions and specifications before selecting the final equipment.
