[0045] The effects achieved by the embodiment are as follows: compared with the prior art, by arranging the opening and closing cleaning mechanism 6 and using the guide plates 605 arranged symmetrically on the winding roller 2, the PE winding film wound on the winding roller 2 can be guided, so that the winding is not uneven due to the deviation of the PE winding film during winding. At the same time, before winding the PE winding film, the movement of the moving ring 607 is limited by the positioning plate 611, so that the right guide plate 605 is opened and the adjacent two second contacts 608 are in contact with each other, and the cleaning ring 614 is driven to be attached to the outer surface of the winding roller 2 for movement and cleaning, so as to remove the impurities adhered to the outer surface of the winding roller 2 and reduce the interference during winding of the PE winding film, thereby enhancing the stability of the PE winding film during winding.

[0046] The complete use steps and working principle of the above embodiment are as follows:

[0047] In the initial state: the position of the tensioning roller 3 does not deviate, the adjacent two first contacts 504 are in contact with each other, the alarm 508 and the driving motor 510 are not started and operated, and the arc-shaped push plate 516 does not contact the outer surface of the tensioning roller 3. The two first elastic extension columns 506 in the vertical direction have the same elastic force acting on the sleeve ring 505, so that the tensioning roller 3 is kept at the center between the two second side plates 507.

[0048] The outer surfaces of both ends of the winding roller 2 are provided with guide plates 605. The left guide plate 605 is integrally fixed on the outer surface of the winding roller 2. The right guide plate 605 is composed of two semicircular plate bodies which are connected to each other. A sliding frame 603 is symmetrically arranged on each semicircular plate body structure. The right guide plate 605 is rotatably connected with the winding roller 2. The moving ring 607 does not contact the outer surface of the winding roller 2. The second contacts 608 are symmetrically arranged on the outer surface of the moving ring 607. The second contacts 608 are synchronously arranged on the inner wall of the profiling groove 612. The adjacent two second contacts 608 do not contact each other. The profiling groove 612 is formed in a shape matching the end of the moving ring 607, so as to facilitate subsequent clamping of the moving ring 607 into the profiling groove 612.

[0049] The following is the working process of the tensioning warning control mechanism 5 for monitoring the change of the tensioning force of the tensioning roller 3 and issuing a warning while pushing the tensioning roller 3 back to the initial position when the position of the tensioning roller 3 deviates:

[0050] When the tensioning force of the tensioning roller 3 changes and causes the position thereof to deviate up and down, for example, Figure 2 and Figure 4As shown, due to the outer surface of the end of the tensioning roller 3 is provided with a collar 505, and the outer surface of the collar 505 is vertically symmetrical provided with a first elastic expansion column 506, and the other end of the first elastic expansion column 506 is fixedly connected on the second side plate 507, and the second side plate 507 is fixedly connected with the inner side wall of the machine body 1, so as to drive the collar 505 to move synchronously with the upward and downward deviation of the position of the tensioning roller 3, and extrude one of the first elastic expansion columns 506, and the other first elastic expansion column 506 is stretched (it should be noted that when the initial tensioning force of the tensioning roller 3 does not change, the collar 505 is located between the two second side plates 507, and the distance between the collar 505 and the two second side plates 507 is equal, and the position of the tensioning roller 3 can be preliminarily limited by the elastic force of the first elastic expansion column 506, so as to reduce the deviation of the tensioning roller 3), and because the collar 505 is fixedly connected with a sleeve block 501 coaxially arranged on the outer surface of the tensioning roller 3, when the collar 505 moves synchronously with the upward and downward deviation of the position of the tensioning roller 3, the position of the sleeve block 501 changes, and because the sleeve block 501 is symmetrically provided with a monitoring rod 502 on both sides, and the first side plate 503 fixedly connected with the machine body 1 is arranged at the transverse ends of the tensioning roller 3, and the first side plate 503 and the monitoring rod 502 are provided with first contact points 504 on the opposite sides, and the first contact points 504 are in contact with each other when the tensioning roller 3 does not deviate, and with the deviation of the position of the tensioning roller 3, the sleeve block 501 drives the monitoring rod 502 to move synchronously, and separates the two first contact points 504, at this time, the alarm 508 provided at the top of the second side plate 507 can be started under the electrical connection, and the warning notice is sent to the staff to prompt the staff to take measures quickly, so as to reduce the downtime and maintenance cost of the equipment;

[0051] When the tensioning roller 3 deviates and the first contact points 504 are separated to start the alarm 508 to give a warning notice, the driving motor 510 is also started to run, and when the driving motor 510 is started to run, as shown in Figure 2 、 Figure 3 and Figure 4 As shown, the output end of the driving motor 510 is fixedly connected with a rotating shaft 511, and the rotating shaft 511 is rotatably connected between the opposite inner walls of the machine body 1, and the main gear 512 is symmetrically arranged on the outer surface of the rotating shaft 511 at both ends, and the rotation of the driving motor 510 can drive the rotating shaft 511 connected with the output end to rotate on the machine body 1, and the rotation of the rotating shaft 511 can drive the two main gears 512 to rotate synchronously with the rotating shaft 511 as the axis, and the opposite inner walls of the machine body 1 are symmetrically provided with a driven gear ring 513, and the driven gear ring 513 is meshingly connected with the main gear 512, so that when the main gear 512 rotates, the driven gear ring 513 can be driven to rotate on the inner side wall of the machine body 1 by the meshing action between the teeth, as shown inFigure 3 and Figure 4 As shown in FIG. 5, FIG. 6 and FIG. 7, because the body 1 is provided with the straight grooves 509 on the inner wall of the facing side in a ring shape and at equal intervals with the tensioning roller 3 as the axis, it should be noted that the tensioning roller 3 described here is in the unshifted state, at which time the tensioning roller 3 and the driven gear ring 513 are coaxial, and the driven gear ring 513 is also provided with the arc-shaped grooves 514 in a ring shape and at equal intervals, the L-shaped connecting rod 515 is slidably connected in the straight grooves 509, and the L-shaped connecting rod 515 penetrates and is slidably connected in the arc-shaped grooves 514, the arc-shaped push plate 516 is fixedly connected to one end of the L-shaped connecting rod 515 towards the sleeve ring 505, and the arc-shaped push plate 516 is arranged on the outside of the tensioning roller 3. With the rotation and meshing drive of the driving gear 512 to the driven gear ring 513, the arc-shaped grooves 514 can limit the movement of the L-shaped connecting rod 515 between the straight grooves 509 and the arc-shaped grooves 514, push the arc-shaped push plate 516 away from the outer surface of the tensioning roller 3, and finally make the arc-shaped push plate 516 adhere to the outer surface of the tensioning roller 3. The distance between each arc-shaped push plate 516 and the tensioning roller 3 (before shifting) is equal, so that the movement of the arc-shaped push plate 516 can make the tensioning roller 3 centered at the axis of the driven gear ring 513, so that the shifted tensioning roller 3 can be restored to the initial position, thereby realizing the position control of the tensioning roller 3 and the emergency treatment of the shifting condition. Through the mechanical correction at the same time of the early warning, not only the labor intensity of the workers is reduced, but also the stability and reliability of the equipment operation are improved, without manual intervention, the efficiency and accuracy of the emergency treatment are improved, and more serious production accidents caused by fault expansion are avoided;

[0052] The above working process is described in detail in the working process of the winding roller 2 in the above embodiment. Figures 1 to 7 .

[0053] The following is the working process of the guiding opening and closing cleaning mechanism 6 to guide the winding film on the winding roller 2 and to move and clean the outer surface of the winding roller 2:

[0054] In the process of winding the PE winding film by the winding roller 2, the guiding plates 605 symmetrically arranged on the outer surface of both ends of the winding roller 2 can limit the winding range of the PE winding film, so as to avoid the uneven winding of the PE winding film in the winding process, ensure the edges of the wound PE winding film to be neat and wrinkle-free, and thus improve the overall quality and appearance of the product. By limiting the shift of the PE winding film, the guiding plates 605 help to ensure that the PE winding film can be uniformly and stably wound on the winding roller 2 during the winding process. This balanced stress distribution reduces the mechanical stress concentration caused by uneven accumulation of the PE winding film, thereby reducing the wear of the winding roller 2 and its related parts.

[0055] Before the PE winding film is wound to the outer surface of the winding roller 2, the outer surface of the winding roller 2 can be moved and cleaned first, and the specific operation steps are as follows, as shown in Figure 1 、 Figure 5 、 Figure 6 and Figure 7 The guide plate 605 located on the left side of the machine body 1 is fixed to the outer surface of the end of the winding roller 2 in a whole structure, and the guide plate 605 located on the right side of the machine body 1 is combined by two semicircular plate structures, and the right guide plate 605 is movably connected with the winding roller 2. Initially, the two semicircular plate structures of the right guide plate 605 are mutually clamped to form a whole guide plate 605. When in use, the staff can push the moving ring 607 towards the guide plate 605. Since the moving ring 607 is rotatably connected with the two linkage plates 606 and the guide plate 605, when the moving ring 607 moves, the linkage plates 606 can drive the two parts of the guide plate 605 to move towards the opposite ends of the shaft center of the winding roller 2 by linkage. At this time, the two parts of the guide plate 605 lose contact with the winding roller 2, and a gap is formed between the two parts of the guide plate 605. The right inner wall of the machine body 1 is fixedly connected with the combined fixing frame 601, and the combined fixing frame 601 is fixedly connected with the slide rod 602 at both ends. The two semicircular plate structures of the guide plate 605 are symmetrically fixedly provided with the slide 603, and the adjacent two slides 603 are fixedly provided with the reset spring 604 between the inner bottom walls. The reset spring 604 is sleeved outside the slide rod 602, and the slide rod 602 and the slide 603 are slidingly connected. When the moving ring 607 moves towards the guide plate 605, the two semicircular plate structures of the guide plate 605 are separated away from each other, and the slide 603 moves synchronously on the outer surface of the slide rod 602 to separate away from each other. At this time, the reset spring 604 is also stretched, as shown in Figure 5 and Figure 7As shown, due to the symmetrical fixing of the disc 609 at the two ends of the combined fixing frame 601, the disc 609 is fixedly connected with the positioning plate 611 through the second elastic telescopic column 610, and the opposite side of the positioning plate 611 is provided with a profiling groove 612 matched with the shape of the edge of the movable ring 607, so that the worker can push the movable ring 607 between the two positioning plates 611, so that the edge of the movable ring 607 can be clamped into the profiling groove 612, and the elastic force of the second elastic telescopic column 610 can make the edge of the movable ring 607 tightly clamped in the profiling groove 612, thereby strengthening the connection between the movable ring 607 and the positioning plate 611, positioning the movable ring 607, and limiting the separation of the guide plate 605, so that the subsequent cleaning ring 614 passes through, and at the same time, the worker can open the switch of the air cylinder 613, and the cleaning ring 614 connected to the output end of the air cylinder 613 can penetrate from the middle of the movable ring 607, then penetrate the gap formed by the two parts of the guide plate 605, and fit the outer surface of the winding roller 2, clean the outer surface of the winding roller 2, effectively remove the impurities on the surface of the winding roller 2, reduce the interference of the impurities on the subsequent PE winding film winding process, thereby enhancing the stability of the PE winding film winding process;

[0056] The above working process please refer to Figures 1 to 7 .
