Description

Technical Field

[0001] This utility model belongs to the field of tray glue extrusion technology, specifically a tray glue extrusion device that can measure and discharge glue. Background Technology

[0002] A pallet is a horizontal platform device used for assembling, stacking, handling, and transporting goods. It is an indispensable tool in the modern logistics industry. In pallet production, the core role of glue is to achieve a firm connection between components. Especially for the most widely used wooden pallets, glue is required at the connection between the pallet panel and the longitudinal beam, the joints of spliced ​​wooden boards, and the fixing of the pads and the base plate. The pallet glue extrusion device is a special equipment used in various pallet production or bonding processes. Its core function is to apply pressure to meter and discharge glue, so as to achieve precise control of glue usage and avoid problems such as insufficient glue application leading to delamination or excessive glue application leading to waste. Therefore, a pallet glue extrusion device that can meter and discharge glue is needed.

[0003] Existing metering adhesive extrusion devices typically use gear pumps to dispense adhesive in a metered manner. The gear pumps rely on the fluidity of the adhesive to achieve sealing and delivery. However, when metering and dispensing high-viscosity, easily curing adhesives, the adhesive tends to clump together during gear meshing. Furthermore, the gears consume more power during delivery, reducing the efficiency of the gear pump. In addition, the long-term delivery of high-viscosity adhesives overloads the gears, leading to fatigue wear on the gear teeth and reducing the service life of the gear pump, which fails to meet people's needs.
