Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, and more specifically, to a piece of plastic waste processing and crushing equipment. Background Art

[0002] In the production process of plastic products, a lot of waste is often generated. In order to improve the utilization rate of materials, the waste is generally crushed by a crushing device and reused through plastic production equipment to achieve the purpose of material reuse. The existing crushing device is generally provided with a fixed cutter and a movable cutter. The movable cutter rotates and cooperates with the fixed cutter to crush the waste. However, when the fixed cutter or the movable cutter is worn, the distance between the fixed cutter and the movable cutter will change, resulting in larger particles after cutting and crushing, which does not meet the crushing standard. If the fixed cutter and the movable cutter are replaced at this time, the replacement frequency is high and the production cost is high; in addition, the existing fixed cutter and the movable cutter are generally installed in a box. Some of the existing boxes are integral structures, which are not easy to replace and adjust the movable cutter and the fixed cutter. Some boxes adopt a split structure, but when the box is split, a crane is needed to lift the upper half of the box and move it to the rest of the position. Therefore, a relatively large area needs to be reserved in the production area for the crane to enter and perform lifting operations. Utility Model Content
