Description

Technical Field

[0001] The utility model relates to the technical field of edge material recycling, in particular to an edge material recycling device and system. Background Technique

[0002] "Cross film" usually refers to a thin film material with a special structure. In the field of waterproof coiled materials, the cross film is formed by cross-laminating multiple layers of thin films with special formulas, and has properties such as high strength, high elongation rate, and puncture resistance, which can enhance the stability and reliability of waterproof coiled materials. In some other application scenarios, the cross film may also refer to a thin film with cross texture or cross structure, and the specific properties and uses will vary according to the field and specific products where it is located.

[0003] The cross film spiral slitting process is a process of slitting the cross film. In this process, the cross film is placed on a spiral slitting machine, and the film is cut into the required size and shape by a rotating cutter. The spiral slitting process can achieve precise slitting of the cross film and can adjust the slitting size and shape as needed. This process is usually used to produce cross film products of various specifications to meet different application requirements.

[0004] The edge materials generated in the existing cross film spiral slitting process will enter a granulator through a feeding device for crushing and pressing into particles for recycling. When the edge materials enter the feeding port of the feeder, due to the looseness of the edge materials, they may fly and disperse under the influence of air flow or slight disturbance, thus accumulating around the feeding port and gradually blocking the feeding port, making the overly loose edge materials increase the risk of blocking the feeding port.
