The driving motor 14 is connected to one side of the connecting frame 11, and the ends of the connecting shaft 15 are fixedly connected to one end of the opposite group of rollers 12.

[0035] The roller 12 is used to install the conveyor belt 13. The driving motor 14 acts on the roller 12. Under the force transmission of the roller 12, the conveyor belt 13 can be driven to roll to move the position of the plastic pallet to be welded. The connecting shaft 15 connects a group of rollers 12 for force transmission.

[0036] The output end of the driving motor 14 is fixedly connected to the other end of the above-mentioned roller 12, and the bottom end of a set of connecting frames 11 is fixedly connected to a cross bar 16, and the lower end of the cross bar 16 is threadedly connected to a support leg 17;

[0037] The crossbar 16 is used to install a frame between a group of connecting frames 11 and to install the support legs 17, and to provide a stabilizing force for the conveying assembly structure through the contact between the lower end of the support legs 17 and the contact surface;

[0038] A positioning assembly, the positioning assembly includes a positioning frame 21, an adsorption seat 22, an adsorption connecting pipe 23 and an adsorption pipe 24;

[0041] Working principle: After the plastic pallet to be welded is placed on one end of the conveyor belt 13, a rotational force is applied to the roller 12 through the controlled drive motor 14. Under the transmission of force, the multiple rollers 12 rotate to drive the conveyor belt 13 to roll, and the position of the plastic pallet to be welded is moved;

[0042] Next, when the plastic pallet is moved, the following position limiting components are used to move the plastic pallet to a suitable position;

[0051] Working principle: In the above-mentioned position movement of the plastic pallet to be welded, a rotational force is applied to the connecting rod 32 by the controlled positioning motor 31 in advance, and the connecting rod 32 acts on the support rod 33 to rotate the positioning plate 34 in linkage, so that the positioning plate 34 rotates to one end of the positioning frame 21, and limits its position through the interference with the conveyed plastic pallet;
