Description

Technical Field

[0001] This utility model relates to the field of resource recycling and environmental protection technology, and in particular to a waste recycling device for plastic film production. Background Technology

[0002] In modern industrial production, plastic film, with its various advantages, is widely used in many fields such as food packaging and agricultural covering, and its output is increasing daily. Traditional methods of handling plastic film waste mostly involve simple and crude methods such as direct disposal or incineration. Manual recycling of plastic film waste is extremely inefficient, not only consuming a large amount of manpower and resources but also causing waste to accumulate for extended periods, affecting the cleanliness of the production workshop and normal production order, further increasing enterprise operating costs. With environmental protection concepts becoming increasingly popular and relevant environmental regulations becoming more stringent, developing an efficient and environmentally friendly waste recycling device for plastic film production to achieve resource utilization of waste, reduce enterprise production costs, and reduce environmental pollution has become a key issue that the plastic film production industry urgently needs to address.

[0003] However, existing waste recycling equipment for plastic film production has the following drawbacks:

[0004] (1) Plastic waste is usually uneven in size, which is not conducive to subsequent mixing and melting, making it difficult to control the quality and stability of recycled plastics;

[0005] (2) When sucking in waste, it is difficult to adjust the speed and suction of the fan, which can easily cause blockage of the connecting parts, thus wasting time cleaning.

[0006] Therefore, this utility model provides a waste recycling device for plastic film production. Utility Model Content

[0018] (III) Beneficial Effects

[0019] This utility model provides a waste recycling device for plastic film production, which has the following beneficial effects:

[0020] 1. This waste recycling device for plastic film production, through the arrangement of a first motor, a first sprocket, a chain, a second sprocket, a crushing roller, a first gear, and a second gear, firstly starts the first motor to drive the first sprocket to rotate. Under the combined action of the first sprocket and the chain, the second sprocket drives the first gear to rotate, and simultaneously drives the second gear meshing with it to rotate. Under the combined action of the first gear and the second gear, the crushing roller crushes the plastic, breaking the plastic film waste into relatively uniform particles. This helps in subsequent mixing and melting, ensuring the quality stability and consistency of recycled plastics, and reducing product quality problems caused by uneven raw materials.
