Description

Technical Field

[0001] The utility model relates to the technical field of plastic sheet processing, in particular to a plastic sheet edge material recovery device. Background Art

[0002] In the manufacturing process of plastic sheets, they need to be cut into strips of specific specifications, and the cut edges need to be recycled. These waste materials are collected by using recycling equipment. Because plastic has strong plasticity after heating, the collected waste materials can be reprocessed and reshaped to form new processing raw materials, avoiding waste of resources.

[0003] For example, the application number is CN201721308304.X, which is a waste material recovery device for a blister machine. The device comprises: two groups of rollers are arranged on a workbench to realize the transmission of blister materials, a rotating shaft is arranged between the two groups of rollers, two symmetrical blade mounting disks are installed on the rotating shaft, and an annular cutting blade is installed on each blade mounting disk. The blade mounting disk is driven to rotate by a motor to realize high-speed rotation of the annular cutting blade to achieve the cutting of the blister materials. The edge materials generated after cutting are positioned and smoothed by the positioning drum and the smoothing piece, and can be accurately dropped into the collecting frame to prevent the edge materials generated after cutting from falling to the ground, thereby achieving an efficient edge material collection effect. The annular cutting blade, the positioning drum and the smoothing piece are all movably installed. By changing the positions of the three, the cutting of plastic sheets of different sizes and the collection of the edge materials generated by cutting can be realized, which is very practical and convenient.

[0004] However, when the existing plastic recycling device recycles plastic sheet scraps, the plastic scraps are irregularly piled up inside the recycling bin, which takes up a large space and cannot be used to recycle more plastic scraps. At the same time, the cut scraps are uneven in size, and larger scraps will increase the time for subsequent heating and reshaping. Therefore, it is urgent to design a plastic sheet scrap recycling device to solve the above problems. Utility Model Content
