[0026] The lifting assembly 9 includes a ball head rod 91 fixedly connected to the flattening roller group 5, a fixed plate 98 fixedly installed on the ball head rod 91, an extension plate 910 fixedly installed on the base 1, a second spring 99 fixedly connected to the fixed plate 98 and the extension plate 910 at both ends, and an arc-shaped slide seat 92 slidably arranged on the base 1. The lifting assembly 9 also includes a rotating rod 93, an insert block 94, a connecting block 95, a first spring 96 and a connecting rod 97. The rotating rod 93 is rotatably arranged on the arc-shaped slide seat 92, the insert block 94 is slidably arranged on the arc-shaped slide seat 92, and the connecting block 95 is fixedly arranged It is installed on the plug block 94, and the two ends of the first spring 96 are fixedly connected to the connecting block 95 and the arc slide seat 92 respectively. The two ends of the connecting rod 97 are movably connected to the rotating rod 93 and the plug block 94 respectively. The arc slide seat 92 is located below the ball head rod 91, and the arc surface of the arc slide seat 92 is tangent to the ball head end of the ball head rod 91. A through hole for passing the ball head rod 91 is opened on the extension plate 910. Knobs are provided on the end faces of the screw rod 131 and the rotating rod 93, and anti-slip grooves are provided on the knobs. This design can avoid slipping, thereby improving the practicality of the overall structure.

[0027] Working principle: auxiliary roller 2, transfer roller 7 and winding roller 8 are movably arranged on the base 1, wherein the auxiliary roller 2 is used to fix the welding strip body 3 before slitting. Under the staggered turning of the transfer roller 7, the winding roller 8 can be used to wind up the welding strip body 3 after slitting. A flattening roller group 5 is arranged on the bridge plate 4 which is slidably connected with the base 1. The welding strip body 3 is passed around the flattening roller group 5 in sequence, so that the welding strip body 3 can be tightened. At this time, the bridge plate 4 is raised again, so that the welding strip body 3 on the flattening roller group 5 contacts with the circular cutter 6, and then the driving motor 10 on the base 1 is started. The output shaft of the driving motor 10 is connected to the transmission shaft 12 through the pulley group 11, and the transmission shaft 12 rotates accordingly. The circular cutter 6 is connected through the keyway on the transmission shaft 12, so the circular cutter 6 rotates at high speed with the transmission shaft 12, and the welding strip body 3 is cut at the same time. Then the winding roller 8 is rotated, and the two welding strips after slitting can be rolled up separately.

[0028] When it is necessary to lift the bridge plate 4 and the flattening roller group 5, the rotating rod 93 that is movable inside the arc-shaped slide 92 is rotated. Under the action of the connecting rod 97 that is movably connected to the plug block 94 and the rotating rod 93 at both ends, the plug block 94 will slide toward the inside of the arc-shaped slide 92 and disengage from the base 1. At this time, the arc-shaped slide 92 can slide on the base 1, so that the arc-shaped slide 92 does not contact the ball head end of the ball head rod 91. The ball head rod 91 fixed on the bridge plate 4 is fixed with a fixing plate 98, and the fixing plate 98 is further connected to the extension plate 910 through a second spring 99. The extension plate 910 fixed on the base 1 is also provided with a hole for passing the ball head rod 91, so in the second Under the action of the spring 99, the ball head rod 91, the bridge plate 4 and the flattening roller group 5 are driven down to facilitate the addition of the welding strip, and the arc slide 92 is pushed back so that the arc slide 92 contacts the ball head rod 91 again and squeezes the ball head rod 91, so that the ball head rod 91 and the bridge plate 4 slide upward to facilitate the cutting of the circular cutter 6. Then the rotating rod 93 is released, and the connecting block 95 fixed on the plug block 94 also utilizes the first spring 96 to further connect with the arc slide 92. Therefore, under the action of the first spring 96, the plug block 94 will slide toward the outside of the arc slide 92, and then be inserted into the base 1, so as to limit the sliding of the arc slide 92 and lock the overall structure.

[0029] When it is necessary to change the width of the welding strip cut by the circular cutter 6, the screw 131 threadedly connected to the base 1 is rotated, because the end of the screw 131 is connected to the connecting bearing 133 fixed on the circular cutter 6, and the connecting bearing 133 is provided with an auxiliary rod 132 slidably connected to the base 1. Therefore, after the screw 131 is rotated, the circular cutter 6 can be pushed to slide on the transmission shaft 12 to change the distance between the circular cutter 6 and the base 1, while the distance between the flattening roller group 5 and the base 1 is fixed, thereby achieving the effect of changing the width of the welding strip cut by the circular cutter 6. The connecting bearing 133 is divided into an inner ring and an outer ring, and the screw 131 and the auxiliary rod 132 are both arranged on the inner ring of the connecting bearing 133. The connecting bearing 133 is fixedly connected to the circular cutter 6 through its outer ring. Therefore, under the action of the connecting bearing 133, the circular cutter 6 can still rotate at high speed with the transmission shaft 12 to perform cutting.
