[0031] The driving mechanism 7 is arranged on the movable frame 3 , and the driving mechanism 7 is connected to the rotating tube 5 by a clamping mechanism 8 .

[0032] In one embodiment of the present application, the transverse movement mechanism 4 may include an electric guide rail 401 and a sliding seat 402 .

[0033] The electric guide rail 401 is fixedly arranged on the base 1 , the sliding seat 402 is slidably matched with the electric guide rail 401 , and the movable frame 3 is fixedly arranged on the sliding seat 402 .

[0034] In one embodiment of the present application, the movable mechanism 62 may include a linear slide rail 621 , a mounting seat 622 , and a movable block.

[0035] The slider is slidably matched with the annular slide rail 61, the mounting seat 622 is fixedly connected to the slider, the movable block is slidably matched with the linear slide rail 621, the linear slide rail 621 is fixedly arranged on the mounting seat 622, and the contact plate 63 is fixedly connected to the movable block.

[0036] As a possible situation, the linear slide rail 621 described in this embodiment is also provided with a spring (not shown in the figure), and the two ends of the spring are respectively fixedly connected to the linear slide rail 621 and the mounting seat 622, so that the mounting seat 622 and the contact plate 63 are reset by the restoring force of the spring. In the natural state, the multiple contact plates 63 are in a retracted state.

[0037] In one embodiment of the present application, a spring telescopic rod 66 is further provided in the rotating tube 5 , one end of the spring telescopic rod 66 is fixedly connected to one end of the rotating tube 5 , and the other end of the spring telescopic rod 66 is fixedly connected to one end of the movable rod 65 away from the movable frame 3 .

[0038] In one embodiment of the present application, the driving mechanism 7 may include a motor 701 , a driving rod 702 and a second ball 703 .

[0039] Among them, the motor 701 is fixedly set on the movable frame 3, one end of the driving rod 702 is coaxially connected to the output shaft of the motor 701 through a coupling, the second ball 703 is rollingly set on the end of the driving rod 702 away from the motor 701, and the center of the driving rod 702 and the center of the movable rod 65 are on the same axis.

[0040] In one embodiment of the present application, the engaging mechanism 8 may include an outer gear 801 and an inner gear ring 802 .

[0041] The outer wall of the inner gear ring 802 is fixedly connected to the inner wall of the rotating tube 5 , the outer gear 801 is sleeved on the driving rod 702 , and the inner gear ring 802 is matched with the outer gear 801 .

[0042] Specifically, when it is necessary to install the winding roller, the operator first sends a command to the electric guide rail 401 of the transverse movement mechanism 4 through the control button or control system of the equipment. The motor inside the electric guide rail 401 is started, and the rotational motion of the motor is converted into the linear motion of the sliding seat 402 through the screw-nut transmission mechanism. The movable frame 3 moves together with the sliding seat 402 in the direction away from the fixed frame 2. While the movable frame 3 moves, it drives the outer gear 801 and the inner gear ring 802 to separate. At this time, after losing the resistance of the driving rod 702, the movable rod 65 moves outward under the action of the restoring force of the spring telescopic rod 66, so as to contact the lifting effect of the inclined groove on the resistance member 64 and the resistance plate 63, thereby releasing the fixing effect on the original winding roller. Then the relevant personnel remove the original winding roller and put the new winding roller on the rotating tube 5.

[0043] Afterwards, the relevant personnel drive the movable frame 3 to reset. When the movable frame 3 is reset, the driving rod 702 contacts the movable rod 65 and compresses the spring telescopic rod 66 until the movable rod 65 drives multiple contact plates 63 through the inclined groove to contact and fix the inner wall of the new winding roller. At the same time, the outer gear 801 and the inner gear ring 802 are adapted again to drive the new winding roller to rotate through the motor 701 to wind the polyethylene film.

[0044] It can be understood that a plurality of inclined grooves are evenly distributed on the outer circumference of the movable rod 65, and these inclined grooves are inclined at a certain angle. A first ball is installed at one end of the resistance member 64 away from the resistance plate 63, and these balls are tightly matched with the inclined grooves. When the movable rod 65 moves toward the direction close to the fixed frame 2, the inclination angle of the inclined groove makes the first ball slide in the inclined groove, thereby driving the plurality of resistance members 64 and the plurality of resistance members 64 to move synchronously, so that the distance between them is increased to adapt to the installation of winding rollers with different inner diameter sizes.

[0045] In summary, the polyethylene film winding equipment of the embodiment of the present application can adapt to a variety of winding rollers with different inner diameters, and is more convenient for disassembly and assembly of the winding roller, thereby effectively improving the winding efficiency.
