▏Core production equipment

Plastic straw production line is mainly composed of the following core production equipment:

Extruder: responsible for the extrusion of molten plastic raw materials into continuous tubular form, is the core equipment of the production line.

Mold: Installed at the exit of the extruder, it is used to determine the cross section shape and size of the straw to ensure the consistency and accuracy of the straw.

Cooling system: Rapid cooling of extruded thermoplastic tubes to set and maintain dimensional stability.

Cutting device: The cooled continuous pipette is cut into a single pipette according to the preset length.

Suction management of the whole equipment: arrange the cut straws to ensure that the straws are arranged neatly for subsequent packaging.

Packaging equipment: automatically put the straw into a bag or packaging box to complete the final packaging of the product.

▏Extrusion molding process

In the production process of plastic straws, the raw material is first heated to a molten state in an extruder and then extruded through a mold to form a continuous tubular form. Parameters such as temperature, pressure and screw speed of the extruder need to be adjusted according to the raw material type and straw specifications to ensure the stability of the extrusion process and the quality of the product.

▏Cooling and cutting process

The extruded thermoplastic tube immediately enters the cooling system and is quickly cooled by water bath or air cooling to set and maintain dimensional stability. The cooled straws enter the cutting device, which cuts the continuous straws into individual straws according to a preset length. During the cutting process, ensure that the cutting precision and the incision are smooth to avoid breakage of the straw or irregular incision.

▏Absorption management and transportation

The cut straws enter the suction management equipment through the conveyor belt, and the suction management equipment arranges the straws neatly through vibration, pushing material and other ways to facilitate subsequent packaging. The speed of the conveyor belt and suction management equipment must be synchronized with the cutting device to ensure continuity and stability of the production line.

▏Introduction of packaging equipment

Packaging equipment is the last process of the plastic straw production line, which is responsible for automatically loading the sorted straw into a bag or packaging box. Common packaging equipment includes automatic counters, automatic packaging machines and sealing machines. The automatic counter is used to count the number of straws to ensure that the number of straws in each bag or packaging box meets the specifications; Automatic packaging machine will automatically put the straw into a bag or packaging box; The sealing machine seals the packaging bag or packaging box to ensure the tightness and hygiene of the product.

▏Production efficiency factors

The production efficiency of the plastic straw production line is affected by a number of factors, including the type of raw material, extruder performance, mold design, cooling system efficiency, cutting device accuracy and packaging equipment speed. Optimizing these parameters can improve the overall efficiency of the production line, reduce production costs and improve product quality.

▏Common problems of production line

Plastic straw production lines may encounter some problems during operation, such as broken straws, irregular cuts, and inconsistent sizes. These problems may be caused by raw material quality, mold wear, improper temperature control of the extruder, and insufficient precision of the cutting device. To solve these problems, it is necessary to carry out regular equipment maintenance and inspection, timely replacement of worn molds and parts, optimization of production parameters, and ensure the stable operation of the production line.

▏Raw material selection and treatment

The raw materials for the production of plastic straws are usually thermoplastic plastics such as polypropylene (PP) and polyethylene (PE). The selection of raw materials should consider the use of the product, environmental requirements and production costs. Raw materials need to be dried before use to remove moisture and impurities to improve the extrusion effect and product quality. At the same time, the particle size and fluidity of the raw material also need to meet the production requirements to ensure the stability and continuity of the extrusion process.

To sum up, the plastic straw production line is an automatic production equipment that integrates raw material processing, extrusion molding, cooling cutting, management of whole transportation and packaging. By optimizing production parameters and maintaining equipment regularly, the efficiency and product quality of the production line can be improved to meet the market demand for high-quality plastic straws.
