The two special-shaped sheets pass through the upper and lower sides of the guide plate respectively. The guide plate 4 can limit the special-shaped sheet and the guide and limiting structure 5 can guide and limit the special-shaped strip protruding outward on the special-shaped sheet to prevent the special-shaped strip from moving to the welding position during welding and causing damage to the special-shaped strip. Several heating rollers can heat multiple positions on the special-shaped sheet at the same time. After being clamped by the clamping roller mechanism, the heating positions of the two special-shaped sheets can be pressed so that the two special-shaped sheets can be welded together and multiple welds can be formed on the special-shaped sheet, which can effectively improve the welding efficiency. The guide plate adjustment assembly 6 can adjust the position of the guide plate so that the special-shaped strip on the special-shaped sheet is misaligned with the heating roller.

[0063] The working principle of the present invention is as follows: the end of the special-shaped sheet is placed on the traction roller and pressed by the adjustable pressure roller assembly, the rotation of the traction roller can drive the special-shaped sheet to move continuously, the adjustable pressure roller assembly can adjust the height according to the thickness of the special-shaped sheet so as to press the special-shaped sheet, the two special-shaped sheets pass through the upper and lower sides of the guide plate respectively, the guide plate 4 can limit the special-shaped sheet and the guide and limiting structure 5 can guide and limit the special-shaped strip protruding outward on the special-shaped sheet to prevent the special-shaped strip from moving to the welding position during welding and causing damage to the special-shaped strip, a plurality of heating rollers can heat multiple positions on the special-shaped sheet at the same time, and the heating positions of the two special-shaped sheets can be pressed by the clamping roller mechanism after being clamped so as to weld the two special-shaped sheets together and form multiple welds on the special-shaped sheet, which can effectively improve the welding efficiency, and the guide plate adjustment assembly 6 can adjust the position of the guide plate so that the special-shaped strip on the special-shaped sheet is misaligned with the heating roller;

[0064] After the heating roller heats the two special-shaped sheets, when the two special-shaped sheets pass between the upper clamping roller 9 and the lower clamping roller 10, the upper and lower clamping plates can squeeze the heated parts of the special-shaped sheets so that the two special-shaped sheets can be welded together. The No. 1 trough 12 can allow the special-shaped strip to pass through to prevent the special-shaped strip from being squeezed and deformed. The plurality of clamping plates corresponding to the plurality of heating rollers can weld multiple positions of the special-shaped sheets at the same time, which can effectively improve the welding efficiency. The clamping roller lifting assembly 13 can drive the upper clamping roller 9 to rise and fall in the vertical direction so as to adjust the distance between the upper clamping roller and the lower clamping roller. The clamping roller rotating assembly 1 4 can drive the lower clamping roller and the upper clamping roller to rotate synchronously in opposite directions, thereby driving the special-shaped sheet to move, and can reduce the friction between the special-shaped sheet and the two No. 1 lifting drivers 16 can synchronously drive the two connecting blocks to rise and fall in the vertical direction, thereby driving the pressing roller to rise and fall in the vertical direction, and can adjust the height of the pressing roller according to the thickness of the special-shaped sheet so as to press the special-shaped sheet tightly. The connection between the pressing roller 15 and the connecting block 17 is provided with a bearing, which can make the pressing roller rotate synchronously when the traction roller pulls the special-shaped sheet to move, thereby reducing the friction between the pressing roller and the special-shaped sheet and preventing the special-shaped sheet from being scratched;

[0065] The second lifting driver 24 can drive the rotating shaft to move, and the rotating shaft movement can drive the upper connecting rod to rotate along the connection between the upper connecting rod and the fixed plate. At the same time, the rotating shaft movement can also drive the lower connecting rod to move. The movement of the lower connecting rod can pull the lifting plate to lift along the vertical slide slot, thereby driving the upper clamping roller to lift in the vertical direction. The second lifting driver 24 is hinged with the frame 1 so that the angle of the second lifting driver can change with the movement of the upper clamping roller. The limit baffle can limit the upper connecting rod so as to limit the extreme position of the downward movement of the upper clamping roller, thereby preventing the upper clamping roller from damaging the lower clamping roller. The rotary driver can drive the lower clamping roller to rotate. The rotation of the lower clamping roller can drive the lower gear to rotate. The rotation of the lower gear can drive the upper gear to rotate. The rotation of the upper gear can drive the upper clamping roller to rotate and the rotation direction of the upper clamping roller is opposite to that of the lower clamping roller, thereby driving the special-shaped sheet to move. Rotating the adjusting screw 32 can drive the support block to lift in the vertical direction. The support block can support the middle of the upper and lower clamping rollers. The pulley can reduce the contact between the upper and lower clamping rollers and the support when they rotate. The friction between the support blocks can increase the service life of the support blocks and reduce noise. The No. 3 lifting driver 37 can drive the lifting adjustment plate 38 to lift in the vertical direction. The lifting adjustment plate 38 can drive the push rod to move in the vertical direction. The push rod movement can push the horizontal connecting rod to translate in a direction perpendicular to the transmission direction of the special-shaped sheet, so that the position of the guide plate can be adjusted to align the guide limit structure on the guide plate with a number of No. 1 slots. The limit plate 45 can limit the special-shaped sheet. The limit slot can limit and guide the special-shaped strip to prevent the special-shaped strip from moving to the welding position during welding and causing damage to the special-shaped strip. The traction driver 46 can drive the No. 1 traction gear 47 to rotate. The rotation of the No. 1 traction gear 47 can drive the No. 2 traction gear 48 to rotate through the chain 49. The rotation of the No. 2 traction gear 48 can drive the traction roller to rotate to pull the special-shaped sheet. The belt 50 can increase the friction between the special-shaped sheet and prevent the traction roller from idling. The No. 2 slot is correspondingly arranged with the No. 1 slot, and can allow the special-shaped strip to pass to prevent the special-shaped strip from being squeezed and deformed.
