[0002] Plastic pallets are a type of logistics unit used in conjunction with forklifts, shelves and other logistics equipment. They can be used to store, load and transport goods. They are one of the essential logistics equipment in modern logistics warehousing. Plastic pallets have the characteristics of high load-bearing capacity and long service life. They are widely used in the fields of chemical industry, textile, manufacturing and so on. Plastic pallets are usually produced by injection molding or blow molding. In the production process, in order to prevent water accumulation, it is necessary to punch holes in the plastic pallets to avoid water accumulation in the plastic pallets. However, most of the punching devices currently use manual transportation and stacking of punched plastic pallets. Manual punching requires punching holes one by one, and the plastic pallets need to be held and fixed, which has a poor fixing effect and is prone to errors in the actual punching process. Although the existing mechanical punching device has multiple drill bits for punching, the spacing between the multiple drill bits is inconvenient to adjust and needs to be adjusted individually, which consumes a lot of time and is inconvenient for daily use.
