[0021] Beneficial effects of the utility model:

[0022] 1. Move the two stacked pallet bodies to the top surface of the conveyor platform through the conveyor, and block and arrange the two pallet bodies through the baffle to align the left and right ends of the two pallet bodies. At this time, the conveyor and the conveying rollers on the movable block stop rotating, and the movable block is pushed to slide toward the middle along the slide rod by the piston rod of the first hydraulic cylinder, and the clamping mechanism is driven to move synchronously at the same time. After moving to a suitable height, the two lead screws are driven to rotate synchronously by the output shaft of the dual-axis motor, so that the two lead screws push the push block to slide synchronously to the inner end, and the push block drives the clamping column and the stabilizing rod to move synchronously, so that the push block and the stabilizing rod slide along the movable block, and the clamping column slides along the through groove, so that the clamping column abuts against the outer wall of the pallet body, aligning the front and back of the two pallet bodies, completing the positioning of the pallet body, and realizing the precise positioning of the pallet body in multiple directions, ensuring the alignment before welding, thereby improving the welding quality and efficiency.

[0023] 2. The piston rod of the first hydraulic cylinder at the upper end drives the movable block at the upper end to move upward, so that the clamped pallet body at the upper end moves upward synchronously to separate the two pallet bodies. At this time, the hot melt block is moved between the two pallet bodies by the hot melt assembly, so that the bottom surface of the hot melt block is in friction contact with the pallet body at the lower end, and then the pallet body at the upper end is pushed downward again, so that the bottom surface of the pallet body at the upper end is in friction contact with the top surface of the hot melt block, and the inner side walls of the two pallet bodies are heated by the hot melt block. After heating, the hot melt block returns to the initial position, and the pallet body at the upper end continues to move downward, so that the two pallet bodies are abutted against each other to complete welding. After welding is completed, the baffle returns to the initial position and is transported to the right end of the conveyor through the conveyor table to complete the discharge, which improves the positioning accuracy of the pallet body during welding, enhances the firmness and sealing of the welding, improves the welding effect and efficiency, makes the continuous welding of the pallet body more convenient, reduces the direct contact between the operator and the high-temperature components, reduces the safety risks such as scalding, and improves the safety of the working environment.

[0024] 3. The piston rod of the cylinder pushes the connecting block to drive one of the connecting rods to move in the direction of the pallet body, so that the T-shaped slider slides along the guide block through the T-shaped groove. At this time, the connecting rod drives the sleeve to move synchronously. After the hot melt block is moved between the two pallet bodies, the piston rods of the two second hydraulic cylinders push the extension rod downward to make the sleeve slide downward along the connecting rod, and the bottom surface of the hot melt block contacts the top surface of the pallet body at the lower end and then stops. Then the pallet body at the upper end is moved downward. After the bottom surface of the pallet body contacts the top surface of the hot melt block, the two pallet bodies are heated at the same time by the hot melt block. After the heating is completed, the pallet body at the upper end moves upward, so that the hot melt block returns to the initial position, and the pallet body at the upper end moves downward again to abut against the pallet body at the lower end for welding, which facilitates the rapid welding of the pallet body and improves the production efficiency. At the same time, the two pallet bodies are heated to make the welding surface more uniform and the welding effect better. By accurately controlling the movement and heating time of the hot melt block, the stability and reliability of the welding process can be ensured, the welding quality is improved, and the use of pallet hot melt welding is convenient.

[0025] 4. When the hot melt block moves toward the direction between the two tray bodies and retreats to the initial position, the side wall of the hot melt block squeezes and pushes the two triangular scrapers away from each other. At this time, the round tube slides upward along the support rod, and the spring is compressed. The spring squeezes the triangular scraper, so that the triangular scraper and the outer walls of the upper and lower ends of the hot melt block are in friction contact, and the residual melt on the tray on the hot melt block is scraped and cleaned. In particular, the residual heat when the hot melt block retreats makes the scraping effect of the melt on the tray better, reduces the influence of the melt on the heating of the hot melt block, improves the heating efficiency of the hot melt block, and provides favorable conditions for the welding of the tray body.
