[0032] The clamping mechanism 2 comprises a support frame 21, and the front and rear sides of the support frame 21 are provided with slide rails 22, and a clamping plate 23 is commonly suspended on the front and rear slide rails 22. The clamping mechanism 2 is provided with two clamping plates 23 that can move horizontally along the slide rails 22, and the bottoms of the two clamping plates 23 are provided with inward clamping blocks 24, and the ends of the blocks 24 facing the middle are provided with plug-in arc hooks 241, and the plug-in arc hooks 241 are arranged in an arc shape and concave downward. The clamping plates 23 on the left and right sides are controlled by the driving motor 25 to realize the function of tightening inwards or expanding outwards at the same time, and the two sides of the support frame 21 are also provided with displacement sensors 29 for monitoring the moving position of the clamping plates 23;

[0033] See attached for details Figure 3 The clamping mechanism 3 includes a movable plate 32 perpendicular to the moving direction of the clamping plate 23, the top of the movable plate 32 is connected to the piston rod of the cylinder 31, and the cylinder 31 is installed at the top of the clamping plate 23 on one side. The interior of the clamping plate 23 is provided with a fixed plate 231 for horizontal installation of the cylinder 31 and a vertically arranged guide groove 233, and the movable plate 32 is provided with a sliding bracket on the side facing the guide groove 233, and the sliding bracket is obliquely supported between the movable plate 32 in the figure; in order to achieve effective lifting and lowering limit, a limiting groove 232 is provided at the bottom of the clamping plate 23, and the limiting groove 232 is arranged at the end of the guide groove 233 and above the plug-in arc hook 241; in order to facilitate the installation between the support frame 21 and the slide rail 22, a hook 234 is provided at the position where the clamping plate 23 connects with the slide rail 22;

[0034] See Figure 2In order to realize that the two clamping plates 23 can be tightened inwardly or expanded outwardly together along the slide rail 22, one solution is: the driving motor 25 is fixedly mounted on the inner side of the top of the supporting frame 21, and the output end of the driving motor 25 is mounted with a first rotating tooth 251, and the first rotating tooth 251 is meshed with the second rotating tooth 26 on the separation screw, and the separation screw is also mounted on the supporting frame 21, and the separation screw includes a first screw 27 on the left side and a second screw 28 on the right side of the integrated design, and the threads of the first screw 27 and the second screw 28 are opposite in direction, and the clamping plate 23 is provided with a movable thread block corresponding to the thread of the separation screw, and for better regulation, the second rotating tooth 26 is mounted in the middle of the separation screw;

[0036] Working principle: When in use, the film roll is placed on a placement table with a lower groove, and the separation screw is driven to rotate by the driving motor, so that the moving thread block set on the separation screw is tightened inward, and the clamping plate under the moving thread block is also tightened inward. When it is close to the placement table, since the clamping block is provided with an arc hook on the side facing the middle, the film roll is fished out from the bottom to the top through the design of the arc hook. However, in the process of clamping, it is gradually clamped by the clamping plates on the left and right sides and monitored in real time through the displacement sensor. After reaching the specified position, the driving motor is stopped to drive the operation of the separation screw, and then the cylinder on the clamping plate on one side is used to bring The movable plate moves downward to press the roll film, thereby achieving simultaneous fixation of four points at the left and right ends and the upper and lower ends to prevent displacement during lifting. After reaching the designated location through the drive of the walking mechanism, the above operation is performed in reverse to complete the unloading. It should be noted that the walking mechanism in this scheme is a more conventional existing design. This scheme mainly protects the overall design of the walking mechanism, the clamping mechanism and the clamping mechanism. It should also be noted that the walking mechanism can be replaced by an existing design that can be lifted and moved. This method can also achieve the effect of this scheme. At the same time, if the lifting and lifting design is used, the roll film can be better separated from the placement table.
