[0030] Please continue to refer to Figure 1 , the lifting member 200 is placed on the top of the support seat 110, driving the height position of the clamping member 300 to change, thereby adjusting the height of the paper reel, facilitating the reel changing operation;

[0031] The lifting member 200 includes a connecting frame 210 threadedly connected to the top of the support seat 110, and a variable-speed motor 220 screwed to the outside of the connecting frame 210. A connecting groove 211 is formed in the connecting frame 210, and two groups of guide rails 212 are symmetrically connected in the connecting groove 211. The output end of the variable-speed motor 220 extends into the connecting groove 211, and the output end of the variable-speed motor 220 is connected to a driving gear 221. A driven gear 230 meshing and drivingly cooperating with the driving gear 221 is rotatably connected in the connecting groove 111. A threaded lead screw 231 is connected to the driven gear 230, and a threaded seat 240 is threadedly connected to the threaded lead screw 231.

Cooperating with the pneumatic gripper 321, it ensures the stable translation of the paper reel during transportation. When the paper reel moves up and down, the telescopic motor 410 can make the support frame 430 always dock with the paper reel;

[0038] Furthermore, a clamping groove 421 is formed at the top of the bracket 420. A clamping seat 431 integrally formed at the bottom of the support frame 430 is in clamping fit with the clamping groove 421. The clamping seat 431 and the clamping groove 421 are in clamping fit, which facilitates the disassembly and assembly of the support frame 430.

[0039] Working principle: When the utility model is in use, the variable-speed motor 220 works to drive the linkage gear set composed of the driving gear 221 and the driven gear 230 to act, and then drives the threaded lead screw 231 to rotate synchronously, so that the threaded seat 240 moves along the threaded lead screw 231, changing the height position of the clamping member 300, and then adjusting the height of the paper reel to facilitate the roll change operation. At the same time, the paper reel is assisted and supported by the support frame 430 to share the force borne by the pneumatic gripper 321. Cooperating with the pneumatic gripper 321, it ensures the stable translation of the paper reel during transportation.
