Description

Technical Field

[0001] The utility model relates to the technical field of pallet production, in particular to a disassembly and cutting device for pallet processing. Background Art

[0002] Pallets are an indispensable and important tool in logistics and transportation, and are widely used in warehousing, transportation, packaging and other fields. Pallet production usually includes raw material preparation, mold design, injection molding (or other molding methods such as blow molding and pressing), post-processing, quality inspection and other links.

[0003] In the production of plastic pallets, after the pallets are compression-molded, excess plastic will remain at the bottom of the edge of the pallet, so this excess plastic needs to be cut. Since the pallets are transported on conveyor belts after processing, it is difficult to ensure that the pallets are aligned with the cutting blades for plastic pallets of different sizes, resulting in cutting deviations.

[0021] Working principle: When the utility model is in use, the pallet is transported by the conveyor belt 1. When it moves to the lower part of the mounting plate 4, the hydraulic cylinder 5 drives the cutting blade to move upward through the power rod 6 and the flange 8, and drives the limit frame 9 to move downward through the fixing plate 7 and the spring 26. The upper part of the pallet contacts the outer guide rod 16 and is fixed inside the limit rod 13 by the inner guide rod 15. After the limit frame 9 contacts the conveyor belt 1, the power rod 6 continues to move downward, and the spring 26 is compressed, so that the cutting blade installed on the flange 8 cuts the pallet.
