Description

Technical Field

[0001] The invention relates to the technical field of plastic pallet crushing, and in particular provides a recycling and crushing device for an environmentally friendly plastic pallet. Background Art

[0002] At present, the logistics industry is developing rapidly, and logistics equipment is also diverse. Pallets are horizontal platform devices used for the collection, stacking, handling and transportation of goods and products. In terms of cargo packaging, pallet operations have promoted the standardization and modularization of packaging, and even had a significant impact on general production activities other than loading and unloading. Existing pallets are generally made of plastic materials. Plastic pallets are light in weight and easy to use. However, plastic pallets need to meet the load-bearing strength of the goods, so the pallets need to be subjected to pressure tests. On the other hand, plastic pallets need to be crushed and recycled after being damaged for recycling.

[0003] The patent with publication number CN215921030U discloses a crushing device for recycling damaged plastic pallets, which relates to the field of crushing devices. In view of the problems of high energy consumption and uneven crushing of existing plastic pallet crushers, the following scheme is proposed, which includes a table top, one end of the table top is provided with a slide groove along its length direction, and a hydraulic cylinder is arranged at the lower end of the table top, the hydraulic cylinder is arranged along the length direction of the slide groove, and a slider is slidably connected in the slide groove, and the piston rod end of the hydraulic cylinder is fixedly connected to the slider, an adapter frame is arranged at the top of the slider, and a push plate is arranged at one end of the adapter frame, and a pallet is arranged on the side of the push plate away from the adapter frame, and side plates are arranged on both sides of the table top away from one end of the slide groove, and spring grooves are arranged on both groups of side plates. The utility model has a novel structure, and the device effectively solves the problems of high energy consumption and uneven crushing of existing plastic pallet crushers.

[0004] This application improves the recycling and crushing device for environmentally friendly plastic pallets. The pallets are milled by the spiral cutting edge of the hob instead of being directly crushed. This greatly reduces the load and energy consumption of the motor. At the same time, the debris generated is in the form of soft strips or sheets, which is conducive to later recycling work. However, the device requires a single pallet to be placed and crushed during the feeding process. When the first pallet is crushed, the second pallet cannot be placed, and the first one needs to be pushed when the latter section is crushed, which makes loading troublesome.
