Meanwhile, since the fourth driving unit 72 is driven by a motor and screw rod mode, and the fifth driving unit 73 is driven by an air cylinder, on one hand, the fourth driving unit 72 has stronger stability and can position one end of the film roll, and when the air flow in the fifth driving unit 73 fluctuates in an unstable manner, the film roll is still not easy to shake. On the other hand, the fifth driving unit 73 is a pneumatic driving system, and the response speed is relatively high, so that the insertion and clamping of the film roll can be completed more quickly.
Referring to fig. 2, specifically, in this embodiment, two clamping rods 71 are rotatably installed at opposite ends of the winding roller 6, and in the film winding process, when the two clamping rods 71 are clamped by opposite insertion, the clamping rods 71 are rotatably connected with the winding roller 6 through the inserting connectors 74, so that the film is wound subsequently.
Referring to fig. 2, specifically, in the present embodiment, the back sides of the two rotating discs 2 are each fixed with a rotating shaft 21, the rotating shafts 21 are coaxially disposed with the rotating discs 2, and the rotating shafts 21 are rotatably supported by a bearing 22 with a seat at the outer side of the winding frame 1. A main driving motor 23 is fixed on one side of the winding frame 1, and the main driving motor 23 and the rotating shaft 21 are driven by a clamping driving chain 732. In the process of replacing and splicing the film roll, the main driving motor 23 drives the rotating shaft 21 to rotate through the clamping driving chain 732 so as to control the rotating disc 2 to rotate, and therefore the position of the winding roller 6 on the winding frame 1 is adjusted.
The implementation principle is as follows:
referring to fig. 5, 7 and 8, when the film passes between the upper roller set 52 and the lower roller set 53 in the guide mechanism 5, the film is guided into the rotating disk 2 by winding around the lower roller set 53 and the guide roller 54 in the lower roller set 53 in turn, the film is wound by the winding roller 6 in the rotating disk 2, after the winding of the winding roller 6 is completed, the front side and the rear side clamping mechanisms 7 rotate to change positions through the rotating disk 2, the winding roller 6 for film to be wound is changed to the front side, and the corresponding winding roller 6 for film wound is changed to the rear side. The winding mechanism 100 stops feeding the film at this time, and the cutting mechanism 3 starts cutting the film. Meanwhile, in the film cutting process, the upper roller set 52 is driven to lift through the ball screw, the auxiliary sliding rail 55 assists the upper roller set 52 to lift, so that the upper roller set 52 is lifted up integrally, the distance between the upper roller set 52 and the lower roller set 53 is pulled, the subsequent feeding of the film into the guide frame 51 is enabled to be lifted up from the distance between the guide roller 54 in the lower roller set 53 and the guide roller 54 in the upper roller set 52, the winding length of the film between the upper roller set 52 and the lower roller set 53 is increased, when the film in the winding frame 1 stops being conveyed, no material accumulation occurs on the film in the guide frame 51, when the film in the rotating disc 2 finishes, the film in the rotating disc 2 begins to be conveyed again, at the moment, the ball screw drives the upper roller set 52 to descend, the auxiliary sliding rail 55 assists the upper roller set 52 to descend, the whole upper roller set 52 descends downwards, the normal distance between the upper roller set 52 and the lower roller set 53 is restored to the normal distance, and the film is enabled to restore to the normal guide state. Through the operation, the guide cutting without stopping machine is realized.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
