Pallet nail gun

The invention relates to the technical field of a nail gun, in particular to a method for nailing a laminated wood board after nailing and fixing the laminated wood board, and then unscrewing the wood board after fixing the nail. Positioning to improve the efficiency of the workers.

In the process of warehousing management and cargo transportation, most of the goods are stacked on pallets and transported to destinations via various modes of transportation. The conventional pallet is composed of a layer of wood block fixed between two layers of wood chips, and the wood block layer has a gap reserved in the two layers of wood chips, and the wooden block layer is fixed between the two layers of wood blocks, thus forming a traditional wooden pallet. Use the support frame of the stacker to directly penetrate the gap between the two layers of the plank and the block and stack the entire stack to the proper position.

Due to the long-term loading of the pallets and the storage of goods, especially for heavy-duty pallets, the load capacity of the planks is required. The most direct way is to use two stacks of sheet metal to fight. The nail gun is fixedly combined. Since the binding of the pallet mostly relies on the manual use of the nail gun operation, the nailing of the two stacked sheet wood boards requires other positioning tools such as C-clips to avoid overlapping external factors due to external factors. Any movement of the wood board occurs during the nailing process, so it is time-consuming to use the positioning tool repeatedly during the binding process.

In view of this, in order to improve the above-mentioned defects, the inventor of the present invention, based on the practice and experience of the industry for many years, carried out the development and design of related products, and finally produced a pallet nail gun for the operator to stack wood.
