Description

Technical Field

[0001] The invention relates to the technical field of packaging film recycling, in particular to a waste recycling device for plastic packaging film production. Background Art

[0002] In the production process of plastic packaging film, it is usually necessary to perform processing operations such as trimming, which will generate a large amount of long strips of waste. If these plastic wastes are directly discarded, it will not only cause a waste of raw materials, but also pollute the environment. In addition, the size of the edge materials cut during the plastic film winding process is generally small, which is not suitable for winding and collection. The storage and transportation of loose film scraps are also inconvenient, and it takes a lot of manpower and working hours to collect and organize them. Therefore, a waste recycling device for plastic packaging film production is used in the recycling of plastic waste.

[0003] The recycling bin is a recycling device for recycling waste materials of a plastic packaging material, wherein the recycling bin is provided with a recycling rod, the recycling rod comprises a driven wheel arranged on the through hole, the driven wheel has one end movably connected to the motor, the driven wheel is movably connected to the connecting plate at one end away from the motor, and the connecting plate is movably connected to the recycling rod at the side away from the driven wheel. The recycling bin can be conveniently replaced with a waste collection device, which saves time and effort, and enables efficient and orderly recycling of waste materials.

[0004] The above-mentioned waste material recovery device for the production of plastic packaging materials drives the connecting plate to rotate by a motor, and then the connecting plate drives the recovery rod to rotate, so that the plastic production waste materials are collected in an orderly manner. When the recovery rod has completed the collection, the plastic production waste materials are pulled into the recovery bin through the top rod on the turntable. It can achieve the goal of not having to replace the waste collection device, saving time and effort, so that the waste material recovery can be carried out efficiently and orderly. However, in the production process of plastic packaging film, the plastic waste generated is generally strip-shaped waste cut when the film is cleared. It is easy to get entangled during collection, and long-term accumulation can easily cause the waste to be fixed on the equipment, making it difficult to clean and affecting the normal operation of the equipment. In addition, the strip-shaped waste is easy to get entangled on the pulverizing roller during pulverization, which affects the pulverization effect, making it less suitable for use.
