[0001] This utility model relates to the technical field of transparent polyethylene film, and in particular to a transparent polyethylene film winding device. Background Technology

[0002] Transparent polyethylene film is a common type of plastic film made of polyethylene material. It has the characteristics of high transparency, good flexibility, chemical corrosion resistance, and waterproof and moisture-proof properties. Transparent polyethylene film winding is the process of winding the produced polyethylene film into a roll using winding equipment. During the production of transparent polyethylene film, the winding equipment needs to drive the transparent polyethylene film winding roller to rotate and wind the transparent polyethylene film onto the roller.

[0003] The winding process includes the following steps: installing the transparent polyethylene film winding roller to the winding equipment, and then disassembling it after winding is completed;

[0004] Existing transparent polyethylene film winding equipment is generally connected to the slitting equipment as a whole. When winding transparent polyethylene film, the transparent polyethylene film roller and the winding device are not easy to disassemble and install, which increases the time for disassembling and installing the transparent polyethylene film roller, thus affecting the winding speed. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a transparent polyethylene film winding device, which has the effect of facilitating the replacement of transparent polyethylene film rollers and improving winding efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A transparent polyethylene film winding device includes a winding roller frame and a transparent polyethylene film roller disposed between its side walls. A rotating roller is rotatably connected to one side wall of the winding roller frame, and an installation roller is hinged between the side walls of the rotating roller. The transparent polyethylene film roller is slidably connected to the circumferential side of the installation roller. A second clamping plate and a first clamping plate are respectively disposed on both sides of the transparent polyethylene film roller, and both the second clamping plate and the first clamping plate are connected to the installation roller.

[0008] The mounting roller has a clamping groove on its upper circumferential side, and a clamping screw is rotatably connected between the sidewalls of the clamping groove. The second clamping plate is threaded to the circumferential side of the clamping screw through a screw nut.

[0009] In a preferred embodiment, the present invention can be further configured such that: a rotating groove is provided on the circumferential side of the mounting roller, and a clamping screw movably passes through one side wall of the rotating groove and is fixedly connected to a rotating block.

[0010] In a preferred embodiment, the present invention can be further configured such that: two limiting rods are fixedly connected between the side walls of the clamping groove, and the second clamping plate is slidably connected to the circumferential side of the two limiting rods.

[0011] In a preferred embodiment, the present invention can be further configured such that: a threaded groove is provided on the circumferential side of the mounting roller, and the first clamping plate is threadedly connected to the circumferential side of the threaded groove.

[0012] In a preferred embodiment, the present invention can be further configured such that: the rotating roller movably passes through one side of the take-up roller frame and is fixedly connected to a rotating block; a placement arc plate is fixedly connected to one side wall of the take-up roller frame; and the mounting roller is located inside the placement arc plate.

[0013] In a preferred embodiment, the present invention can be further configured such that: a base frame is fixedly connected to the lower end of the take-up roller frame, and double-sided adhesive is fixedly connected to the circumferential side of the transparent polyethylene film roller.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example: Referring to Figures 1-4, the present invention discloses a transparent polyethylene film winding device, including a winding roller frame 1 and a transparent polyethylene film roller 3 disposed between its side walls. A rotating roller 4 is rotatably connected to one side wall of the winding roller frame 1, and an installation roller 5 is hinged between the side walls of the rotating roller 4. The transparent polyethylene film roller 3 is slidably connected to the circumferential side of the installation roller 5. A second clamping plate 9 and a first clamping plate 6 are respectively disposed on both sides of the transparent polyethylene film roller 3, and both the second clamping plate 9 and the first clamping plate 6 are connected to the installation roller 5.

[0024] The upper part of the circumferential side of the mounting roller 5 is provided with a clamping groove 10, and a clamping screw 11 is rotatably connected between the side walls of the clamping groove 10. The second clamping plate 9 is threadedly connected to the circumferential side of the clamping screw 11 through a screw nut.

[0025] In this embodiment, referring to FIG1, the transparent polyethylene film roller 3 is mounted on the mounting roller 5, and the rotating roller 4 can drive the mounting roller 5 to rotate. After the transparent polyethylene film roller 3 is clamped by the first clamping plate 6 and the second clamping plate 9, it can rotate with the mounting roller 5 and the rotating roller 4.

[0026] Referring to Figure 3, the specific installation method of the transparent polyethylene film roller 3 is as follows: Rotate the mounting roller 5 upward so that the mounting roller 5 is perpendicular to the rotating roller 4. After the transparent polyethylene film roller 3 is placed on the mounting roller 5 from above, rotate the mounting roller 5 so that the mounting roller 5 is in a horizontal state. Rotate the clamping screw 11, and the second clamping plate 9 moves on the surface of the clamping screw 11 through the screw nut. The second clamping plate 9 moves and reaches one end of the transparent polyethylene film roller 3. Move the first clamping plate 6 and attach it to the other end of the transparent polyethylene film roller 3. Thus, the transparent polyethylene film roller 3 can be clamped between the first clamping plate 6 and the second clamping plate 9. After fixing the transparent polyethylene film on the surface of the transparent polyethylene film roller 3, rotate the rotating roller 4 to drive the transparent polyethylene film roller 3 to rotate, which can roll up the transparent polyethylene film. This makes it convenient to install and collect the transparent polyethylene film roller 3 and convenient to use.

[0027] Preferably, referring to Figure 1, the rotation mode of the rotating roller 4 and the mounting roller 5 is such that the mounting roller 5 can only rotate upwards, and after rotating to the same horizontal line as the rotating roller 4, it cannot continue to rotate downwards.

[0028] Furthermore, please refer to Figure 3 for details. The circumferential side of the mounting roller 5 is provided with a rotating groove 13. The clamping screw 11 movably passes through one side wall of the rotating groove 13 and is fixedly connected to a rotating block 14.

[0029] In this embodiment, the rotating block 14 can be rotated by hand, thereby driving the clamping screw 11 to rotate. The second clamping plate 9 moves on the surface of the clamping screw 11, so that the position of the second clamping plate 9 can be adjusted to clamp the transparent polyethylene film roller 3.

[0030] Furthermore, please refer to Figure 3 for details. Two limiting rods 12 are fixedly connected between the side walls of the clamping groove 10, and the second clamping plate 9 is slidably connected to the circumferential side of the two limiting rods 12.

[0031] In this embodiment, the second clamping plate 9 moves linearly across the surface of the limiting rod 12, which can improve the movement stability of the second clamping plate 9.

[0032] Furthermore, please refer to Figures 2 and 4 for details. A threaded groove 8 is provided on the circumferential side of the mounting roller 5, and the first clamping plate 6 is threadedly connected to the circumferential side of the threaded groove 8.

[0033] In this embodiment, referring to FIG4, after the transparent polyethylene film roller 3 is placed on the mounting roller 5, the first clamping plate 6 is rotated so that the first clamping plate 6 moves through the threaded groove 8. After the mounting roller 5 is rotated so that the mounting roller 5 is horizontal, the second clamping plate 9 is moved and the first clamping plate 6 is rotated to abut the other end of the transparent polyethylene film roller 3, thereby clamping and fixing the transparent polyethylene film roller 3 between the second clamping plate 9 and the first clamping plate 6.

[0034] Further details are shown in Figure 1. The rotating roller 4 extends through one side of the take-up roller frame 1 and is fixedly connected to a rotating block 16. A placement arc plate 7 is fixedly connected to one side wall of the take-up roller frame 1, and the mounting roller 5 is located inside the placement arc plate 7.

[0035] In this embodiment, after the mounting roller 5 rotates, a portion of the circumferential side of the mounting roller 5 is in contact with the inner circumferential wall of the placement arc plate 7. The placement arc plate 7 can provide a support effect for the mounting roller 5 without affecting the rotation of the mounting roller 5. The rotating block 16 can rotate the rotating roller 4 to achieve the purpose of rotating the mounting roller 5 and the transparent polyethylene film roller 3.

[0036] Preferably, although not shown in the figure, transparent protective shells can be configured on both the winding roller frame 1 and the base frame 2. The transparent protective shells are snapped together, and a film groove is opened on the transparent shell. The transparent polyethylene film passes through the film groove and is wound onto the transparent polyethylene film roller 3. The rotating block 16 is located outside the transparent shell and can drive the transparent polyethylene film roller 3 to rotate, which can achieve the purpose of dust prevention during winding.

[0037] Furthermore, please refer to Figure 2 for details. The lower end of the take-up roller frame 1 is fixedly connected to the base frame 2, and the circumferential side of the transparent polyethylene film roller 3 is fixedly connected to the double-sided adhesive tape 15.

[0038] In this embodiment, during use, the rotating roller 4 can be placed on the ground or table via the base frame 2, and then the transparent polyethylene film roller 3 can be rotated to wind up the transparent polyethylene film. The release paper on the double-sided tape 15 is torn off, and the end of the transparent polyethylene film is to be stuck to the double-sided tape 15. The transparent polyethylene film roller 3 can rotate continuously to wind up the transparent polyethylene film.

[0039] The implementation principle of the above embodiment is as follows: When the transparent polyethylene film is wound up by the transparent polyethylene film roller 3, the mounting roller 5 is rotated upward so that the mounting roller 5 is perpendicular to the rotating roller 4. After the transparent polyethylene film roller 3 is placed on the mounting roller 5 from above, the mounting roller 5 is rotated so that the mounting roller 5 is in a horizontal state. The clamping screw 11 is rotated, and the second clamping plate 9 moves on the surface of the clamping screw 11 through the screw nut. The second clamping plate 9 moves and reaches one end of the transparent polyethylene film roller 3. The first clamping plate 6 is moved and fits against the other end of the transparent polyethylene film roller 3, so that the transparent polyethylene film roller 3 can be clamped between the first clamping plate 6 and the second clamping plate 9. After the transparent polyethylene film is fixed on the surface of the transparent polyethylene film roller 3, the rotating roller 4 is rotated to drive the transparent polyethylene film roller 3 to rotate, which can wind up the transparent polyethylene film. This makes it convenient to install and collect the transparent polyethylene film roller 3, and is convenient to use.
