Description

Technical Field

[0001] This utility model relates to the field of plastic pallet processing technology, specifically to a cutting and trimming device for plastic pallet production. Background Technology

[0002] Plastic pallets are logistics units used in conjunction with forklifts, racks, and other logistics equipment. They are used to store, load, and move goods and are an indispensable piece of logistics equipment in modern warehousing. The emergence of plastic pallets is in line with environmental protection needs. Using plastic pallets instead of wooden pallets is the best way to reduce damage to forests. With the increasing emphasis on food safety and the high hygiene requirements of the pharmaceutical industry, plastic pallets are favored and sought after by the food and pharmaceutical industries for their characteristics such as corrosion resistance, moisture resistance, rust resistance, insect resistance, and mold resistance.

[0003] A search revealed a patent publication dated September 10, 2024, in China, number CN221677311U, for a cutting and trimming device used in the production of plastic pallets. The device is described as follows: It includes a base plate with four support columns fixedly connected to its upper surface. Each support column has a fixed frame fixedly connected to its top. The inner wall of the fixed frame has symmetrical grooves, and two sliding plates are slidably connected to each other within the grooves. The upper surface of the sliding plate has a through hole, and a forward / reverse motor is mounted on its upper surface. A first electric push rod is fixedly connected to the upper surface of the fixed frame. The output end of the first electric push rod is fixedly connected to the right side of the forward / reverse motor. The angle of the cutting blade can be adjusted via the forward / reverse motor. The position of the cutting blade can be adjusted using the cooperation of the first electric push rod and the sliding plate, facilitating the trimming of plastic pallets of different sizes. The plastic pallets can be cut and trimmed using the cooperation of a hydraulic rod and the cutting blade.

[0004] While the aforementioned existing technical solution facilitates the trimming of plastic pallets of different sizes, the device can only adjust the cutting blade by moving it left and right, resulting in limited applicability of the equipment. Utility Model Content
