Description

Technical Field

[0001] The present application relates to the field of plastic recycling technology, and in particular to a plastic recycling and reuse device for the production of embedded patches in drip irrigation tapes. Background Art

[0002] The plastic used to produce the embedded patches in the drip irrigation tape refers to the polymer material used to manufacture the built-in patches in the drip irrigation tape. It is usually made of thermoplastic plastic and has good weather resistance, aging resistance, pressure resistance and chemical corrosion resistance. During the production process, plastic particles are injection molded or extruded into patches with a specific structure, which are used to accurately control the water flow rate and flow of the drip irrigation tape. Due to the production process requirements, the embedded patches in the drip irrigation tape need to have high dimensional accuracy and mechanical strength. Therefore, a certain proportion of scraps, waste or overflow will be generated in the production process, such as injection runner materials, flash, and defective products.

[0003] In the traditional plastic recycling process of embedded patch production of drip irrigation tape, the existing recycling device usually only adopts a simple single-stage crushing structure. The crushed plastic particles often have the problem of uneven particle size. Larger particles will directly affect the subsequent melting uniformity and the quality of recycled plastics. In addition, due to the lack of an effective screening mechanism, substandard plastic fragments will directly enter the recycling process, which will not only easily cause blockage of the injection molding machine feed port, but also reduce the mechanical properties of the recycled plastics. At the same time, the traditional device cannot automatically sort and secondary crush unqualified particles, resulting in some waste materials requiring manual intervention, which increases production costs and reduces recycling efficiency. In addition, the existing equipment generally lacks impurity separation function, and foreign matter such as metal debris may be mixed into the recycling system, which not only affects the service life of the equipment, but also causes product quality risks. In addition, the degree of automation is low, and the entire recycling process requires frequent manual intervention, making it difficult to achieve continuous and efficient production. These problems seriously restrict the recycling efficiency of drip irrigation tape production waste and the product quality of recycled plastics. Summary of the Invention
