[0006] In order to achieve the above purpose, the utility model is realized by the following technical solutions: a winding device for conveniently removing a plastic film, including a frame and a winding structure; the winding structure is arranged on the frame; the winding structure includes a driving sprocket, a plurality of guiding sprockets, a drum for winding the film, a winding roller inserted into the drum, a winding sprocket installed on one side of the winding roller, a base for supporting the winding sprocket, a slide rail for the base to slide, and a driving member for driving the base to slide;

[0007] The driving sprocket drives the winding sprocket to rotate through a chain, and one of the guiding sprockets cooperates with the driving sprocket to bypass the chain above the winding sprocket, so that the winding sprocket is close to the base;

[0008] A sleeve with a hexagonal slot is fixed at one end of the winding sprocket, and an insertion shaft corresponding to the sleeve is arranged on one side of the winding roller corresponding to the winding sprocket, and the insertion shaft is inserted into the sleeve.

[0009] Preferably, the base has a semi-circular arc-shaped notch for placing the winding sprocket, and a plurality of rollers acting on the sleeve are arranged on the edge of the notch.

[0014] Preferably, a window is provided on one side of the frame for placing the winding sprocket.

[0015] Advantageous Effects

[0016] In the present utility model, by mounting the winding sprocket on the base, and at the same time, by arranging the chain to bypass over the winding sprocket, the winding sprocket is made to closely adhere to the base, further enhancing the stability of the overall structure, preventing the winding roller from shifting or falling off during rotation, and at the same time enabling the winding sprocket to operate at a relatively high speed, thereby improving the winding efficiency.

[0023] To make the technical means, creative features, achieved objectives, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution for a winding device that facilitates the removal of a plastic film: including a frame 1 and a winding structure; the winding structure is arranged on the frame 1; the winding structure includes a driving sprocket 21, a plurality of guiding sprockets 22, a drum 23 for winding the film B, a winding roller 24 inserted into the drum 23, a winding sprocket 25 installed on one side of the winding roller 24, a base 26 for supporting the winding sprocket 25, a slide rail 27 for the base 26 to slide, and a driving member 28 for driving the base 26 to slide; in one embodiment, the driving sprocket 21 drives the winding sprocket 25 to rotate to wind the plastic film B. Among them, the driving sprocket 21 is driven by a motor to rotate.

[0025] Further, in order to realize the rotation of the winding sprocket 25 to complete the winding work, the driving sprocket 21 drives the winding sprocket 25 to rotate through a chain A. In one embodiment, there are 3 guiding sprockets 22, and the 3 guiding sprockets 22 are distributed in a rectangle with the driving sprocket 21, and the chain A extends from the driving sprocket 21 in sequence and passes through the winding sprocket 25 and the 3 guiding sprockets 22 to form a cycle.

[0026] The provided slide rail 27, base 26, and driving member 28 are used to drive the drum 23, winding roller 24, and winding sprocket 25 to displace, so as to facilitate subsequent disassembly and assembly work; specifically, by the piston of the driving member 28 as a cylinder extending forward, the base 26 moves along the slide rail 27, so that the winding sprocket 25 on the base 26 is released from the restraint of the chain A, and thus the drum 23 can be replaced.

[0027] Among them, in order to realize that the winding sprocket 25 can drive the winding roller 24 and the drum 23 to rotate, so as to wind the plastic film B, one end of the winding sprocket 25 is fixed with a sleeve 251 having a hexagonal slot, and the winding roller 24 is provided with an insertion shaft 241 corresponding to the sleeve 251 on the side corresponding to the winding sprocket 25, and the insertion shaft 241 is inserted into the sleeve 251; thus when the winding sprocket 25 rotates, by using the clamping connection between the sleeve 251 and the insertion shaft 241, the purpose of the winding sprocket 25 driving the winding roller 24 and the drum 23 to rotate is realized. At the same time, the winding sprocket 25 can be separated from the winding roller 24, so as to facilitate the replacement of the drum 23.

[0028] Further, since the driving member 28 will drive the winding sprocket 25 to displace, and in order to completely release the restraint of the chain A on the winding sprocket 25, therefore, on the guiding sprocket 22 located below the winding sprocket 25, a secondary wheel 29 is provided on one side; the secondary wheel 29 is located between the guiding sprocket 22 and the winding sprocket 25, and the chain A bypasses from the upper side of the secondary wheel 29. Thus, when the winding sprocket 25 displaces, refer to Figures 1-2 , when the winding sprocket 25 moves beyond the position of the secondary wheel 29, the extra buffer length A1 in the chain A will loosen the winding sprocket 25, so as to facilitate the removal of the winding sprocket 25.

[0029] Further, to facilitate the installation of the winding structure on the rack 1, a window 3 is provided on one side of the rack 1 for placing the winding sprocket 25.

[0030] The base 26 has a semi-circular notch 261 for placing the winding sprocket 25. A number of rollers 262 acting on the sleeve 251 are provided on the edge of the notch 261, so that the winding roller 24 can rotate on the base 26. Further, to prevent the winding roller 24 from running out of the notch 261 during rotation, one of the guide sprockets 22 cooperates with the drive sprocket 21 to wind the chain A around the winding sprocket 25, making the winding sprocket 25 close to the base 26.

[0031] Working principle: The drive sprocket 21 rotates, and the chain A is used to drive the winding sprocket 25 and each guide sprocket 22 and the auxiliary wheel 29 to rotate, thereby completing the winding work.

[0032] After the winding is completed, the piston of the driving member 28 extends forward to move the winding sprocket 25 to the left side of the window 3. During this period, the winding sprocket 25 exceeds the position of the auxiliary wheel 29, so that the buffer length A1 in the chain A is released, freeing the chain A from binding the winding sprocket 25, thus facilitating the disassembly of the winding sprocket 25 by the staff;

[0033] Pull out the winding sprocket 25 from the winding roller 24, then re-insert the new winding roller 24 and the drum 23, and insert the winding sprocket 25 again to complete the replacement of the old with the new. Then, the driving member 28 is reset to complete the binding of the winding sprocket 25.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0035] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
