[0024] A positioning assembly 6 is provided between the sliding bracket 3 and the lifting device 5. The positioning assembly 6 includes a positioning pin group and a positioning pin seat. The positioning pin group is installed at the lower end of the sliding bracket 3. The positioning pin seat is fixedly connected to the side of the lifting device 5. The positioning pin group cooperates with the positioning pin seat pin. Its working principle is as follows: the slewing bracket 4 can control the rotation of the adjustment bracket 1 through the lifting device 5 to swap the two ends of the film roller. After the swap is completed, the positioning pin group at the lower end of the sliding bracket 3 will cooperate with the positioning pin seat on the outside of the lifting device 5 to limit the lifting device 5 from continuing to rotate, thereby avoiding the deflection of the adjustment bracket 1 during the conveying process, improving the safety of loading and unloading the film roller, and protecting the slewing bracket 4.
[0025] The specific structure of the adjustment bracket 1 is described below;
[0026] The adjusting bracket 1 includes an adjusting frame 101, in which two nut seats 103 are arranged inside the adjusting frame 101, the nut seats 103 are slidingly connected to the inner wall of the adjusting frame 101, the lower end of the nut seat 103 is fixedly connected to the upper end of the clamping jaw 2, and a double-headed screw 104 is arranged inside the adjusting frame 101, the double-headed screw 104 penetrates the two nut seats 103, the positive thread and the reverse thread on the outside of the double-headed screw 104 are respectively matched with the threads of the two nut seats 103, and a first motor 102 is arranged outside the adjusting frame 101, and the output end of the first motor 102 is fixedly connected to one end of the double-headed screw 104.
[0027] The first motor 102 drives the double-headed screw 104 to rotate, and the double-headed screw 104 cooperates with the two nut seats 103 to drive the two nut seats 103 to move horizontally along the rod of the double-headed screw 104. Due to the different rotation directions of the outer threads of the double-headed screw 104, when the double-headed screw 104 rotates, the two nut seats 103 will move in opposite directions, ensuring that the clamping claws 2 fixed at the lower end of the nut seats 103 can effectively fix the two ends of the film roller.
[0028] The specific structure of the lifting device 5 is described below.
[0029] The lifting device 5 includes a hydraulic push rod 501 and a second fixed frame 502. The mounting end of the second fixed frame 502 is rotatably connected to the lower end of the sliding bracket 3. The output end of the second fixed frame 502 is fixedly connected to the upper end of the adjusting bracket 1. The hydraulic push rod 501 is sleeved outside the second fixed frame 502. The hydraulic push rod 501 is fixedly connected to the second fixed frame 502.

The mounting end of the second motor 404 is fixedly connected to the first fixed frame 401, and the output end of the second motor 404 is fixedly connected to one end of the worm 403.
[0032] The slewing bracket 4 adopts a worm gear transmission to control the rotation of the adjusting bracket 1. When working, the second motor 404 drives the worm 403 to rotate. Since the worm 403 is meshed with the worm wheel 402, it can drive the worm wheel 402 to rotate. Since the worm wheel 402 is fixed to the upper end of the hydraulic push rod 501 through the fixed shaft 405, when the worm wheel 402 rotates, the hydraulic push rod 501 will also drive the adjusting bracket 1 to rotate, and the two ends of the film roller are swapped.
