[0003] After the plastic film is processed, it needs to be wound. When the plastic film is wound, there are generally guide rollers and tension adjusting rollers in the transmission assembly. When replacing the winding roller, the plastic film needs to be cut off. When the existing plastic film winding device is in use, the plastic film cannot be fixed, so that the plastic film slips off from components such as external guide rollers and external tension adjusting rollers under the action of the guide rollers and tension adjusting rollers. When winding again, the plastic film needs to be re-passed through the external guide rollers and external tension adjusting rollers, thereby affecting the winding efficiency of the winding film.

[0004] Therefore, it is necessary to provide a new plastic film winding device to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a plastic film winding device for improving winding efficiency.

[0006] The plastic film winding device provided by the utility model includes: a base, the upper surface of the base is fixedly connected with side plates; a winding mechanism, the winding mechanism is connected with the side plates; a pressing roller mechanism, the pressing roller mechanism is connected with the side plates and the base, and the pressing roller mechanism is located in front of the feeding end of the winding mechanism; the pressing roller mechanism includes a top U-shaped mounting seat, the top U-shaped mounting seat is connected with the side plates, and a top rotating roller is rotatably connected inside the top U-shaped mounting seat; a bottom U-shaped mounting seat is slidably connected with the side plates through a connecting rod, and a bottom rotating roller is rotatably connected inside the bottom U-shaped mounting seat, and the bottom rotating roller is located directly below the top rotating roller; a threaded rod is rotatably connected to the upper surface of the base, and the threaded rod penetrates through the bottom U-shaped mounting seat and is threadedly connected with the bottom U-shaped mounting seat.

[0007] Preferably, it further includes a fixing plate, the fixing plate is fixedly connected with the side plates, and a limiting rod passing through the fixing plate is slidably connected to the fixing plate, and the bottom of the limiting rod is fixedly connected with the top U-shaped mounting seat; the top U-shaped mounting seat is slidably connected with the side plates, and the top U-shaped mounting seat is elastically connected with the fixing plate through a spring.

[0008] Preferably, the winding mechanism includes a turntable, which is rotatably connected to the side plate, and a motor for driving the turntable to rotate is installed on the side plate. The side plate is fixedly connected with a hexagonal rod that rotates coaxially, and the hexagonal rod is clamped into a hexagonal card slot opened at one end of the winding roller.

[0009] Preferably, it further includes a pressing piece, and the pressing piece is elastically connected in a groove opened on the outer surface of the winding roller through an elastic connecting piece.

[0010] Preferably, one end of the pressing piece extends to the outside of the winding roller.

[0013] Compared with the related technology, the plastic film winding device provided by the present invention has the following beneficial effects:

[0014] 1. Before cutting the plastic film, by rotating the threaded rod clockwise, the bottom U-shaped mounting seat and the bottom rotating roller move upward, and then the plastic film is squeezed and fixed through the bottom rotating roller and the top rotating roller. When cutting the plastic film, the plastic film located between the bottom rotating roller and the winding roller is cut. Therefore, the cutting end face of the plastic film will not move under the action of the external guide roller and the external tension adjusting roller, that is, the plastic film will not slip off from components such as the external guide roller and the external tension adjusting roller. Therefore, when winding again, it is not necessary to re-thread the plastic film through the external guide roller and the external tension adjusting roller, which reduces the burden on the operator and improves the winding efficiency of the plastic film.

[0015] 2. By the operation of the air pump, the air outlet at the bottom of the air outlet plate can discharge air, and when the plastic film is wound, it passes through the bottom of the air outlet plate. The airflow blown out by the air outlet plate can blow off dust and other impurities on the surface of the plastic film, which is beneficial to the winding of the plastic film.

[0016] 3. The plastic film is squeezed and fixed through the bottom rotating roller and the top rotating roller. At this time, it is not necessary to turn off the air pump, which reduces the frequency and number of times of turning on and off the air pump switch, and improves the service life of the air pump.

Specific embodiments

[0023] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Please refer to in conjunction with Figures 1 to 5 , a plastic film winding device includes: a base 5, the upper surface of the base 5 is fixedly connected with a side plate 4; a winding mechanism 1, the winding mechanism 1 is connected with the side plate 4; a pressure roller mechanism 2, the pressure roller mechanism 2 is connected with the side plate 4 and the base 5, and the pressure roller mechanism 2 is located in front of the feeding end of the winding mechanism 1; the pressure roller mechanism 2 includes a top U-shaped mounting seat 28, the top U-shaped mounting seat 28 is connected with the side plate 4, and a top rotating roller 27 is rotatably connected inside the top U-shaped mounting seat 28; the bottom U-shaped mounting seat 24 is slidably connected with the side plate 4 through a connecting rod 26, and a bottom rotating roller 25 is rotatably connected inside the bottom U-shaped mounting seat 24, and the bottom rotating roller 25 is located directly below the top rotating roller 27; a threaded rod 23 is rotatably connected to the upper surface of the base 5, and the threaded rod 23 penetrates through the bottom U-shaped mounting seat 24 and is threadedly connected with the bottom U-shaped mounting seat 24.

[0025] It should be noted that: after the plastic film passes through the external conveying assembly, it then enters the pressure roller mechanism 2 and is finally wound by the winding mechanism 1; and in order to ensure the flatness of the plastic film and facilitate conveying, there will be external guide rollers and external tension adjusting rollers in the external conveying assembly; when the winding roller 12 on the winding mechanism 1 needs to be replaced, the plastic film needs to be cut by a cutting knife;

[0026] Before cutting the plastic film, by rotating the threaded rod 23 clockwise, the bottom U-shaped mounting seat 24 and the bottom rotating roller 25 move upward, and then the plastic film is squeezed and fixed by the bottom rotating roller 25 and the top rotating roller 27. When cutting the plastic film, the plastic film located between the bottom rotating roller 25 and the winding roller 12 is cut. Thus, under the action of the external guide roller and the external tension adjusting roller, the cutting end face will not move, that is, the plastic film will not slip off from components such as the external guide roller and the external tension adjusting roller. Therefore, when winding again, it is not necessary to re-thread the plastic film through the external guide roller and the external tension adjusting roller, reducing the burden on the operator and improving the winding efficiency of the plastic film;

[0027] It should also be noted that after replacing the new winding roller 12, rotate the threaded rod 23 counterclockwise to reset the bottom rotating roller 25, so that the bottom rotating roller 25 and the top rotating roller 27 no longer squeeze and fix the plastic film, which is beneficial to the re-winding of the plastic film.

[0028] Reference Figure 4 As shown in the figure, it further includes a fixing plate 29. The fixing plate 29 is fixedly connected to the side plate 4, and a limiting rod 21 passing through it is slidably connected to the fixing plate 29. The bottom of the limiting rod 21 is fixedly connected to the top U-shaped mounting seat 28; the top U-shaped mounting seat 28 is slidably connected to the side plate 4, and the top U-shaped mounting seat 28 is elastically connected to the fixing plate 29 through a spring 22.

[0029] It should be noted that through the spring 22, the top U-shaped mounting seat 28 can be elastically slidably connected relative to the fixing plate 29 and the side plate 4. Under the action of the elastic restoring force of the spring 22, when the plastic film is wound, the top rotating roller 27 will contact the plastic film, thereby playing a role in guiding and tensioning the plastic film, which is beneficial to the winding of the plastic film.

[0030] Reference Figure 1 and Figure 3 As shown in the figure, the winding mechanism 1 includes a turntable 14. The turntable 14 is rotatably connected to the side plate 4, and the side plate 4 is provided with a motor 13 for driving the turntable 14 to rotate. The side plate 4 is fixedly connected to a coaxial rotating hexagonal rod 15, and the hexagonal rod 15 is clamped into a hexagonal groove opened at one end of the winding roller 12.

[0031] It should be noted that when the motor 13 works, it can drive the turntable 14 and the hexagonal rod 15 to rotate, and then drive the winding roller 12 to rotate. The plastic film is wound onto the winding roller 12. By pulling the winding roller 12, the hexagonal rod 15 slides out of the hexagonal groove, and then the winding roller 12 can be removed, which is beneficial to the replacement of the winding roller 12.

[0032] It should also be noted that a rubber pad is fixedly connected to the outer surface of the hexagonal rod 15, and the hexagonal rod 15 is clamped in the hexagonal card slot through the rubber pad.

[0033] Reference Figure 3 As shown, it further includes a pressing piece 11, and the pressing piece 11 is elastically connected in a groove formed on the outer surface of the winding roller 12 through an elastic connecting piece; one end of the pressing piece 11 extends to the outside of the winding roller 12.

[0034] It should be noted that by pulling the pressing piece 11, one end of the plastic film can enter the groove. After releasing the pressing piece 11, the pressing piece 11 and the winding roller 12 are used to squeeze and fix one end of the plastic film, which is beneficial to the rapid squeezing and fixing of the plastic film.

[0035] Reference Figure 2 and Figure 5 As shown, the side plate 4 is connected with a blowing and cleaning mechanism 3, and the blowing and cleaning mechanism 3 is located in front of the feeding end of the top rotating roller 27; the blowing and cleaning mechanism 3 includes an air pump 33, the air pump 33 is connected with the side plate 4, and the air outlet of the air pump 33 is connected with one end of a guide air pipe 32, and the other end of the guide air pipe 32 is connected with an air outlet plate 31, and the air outlet direction of the air outlet plate 31 is downward.

[0036] It should be noted that when the air pump 33 works, the air outlet at the bottom of the air outlet plate 31 can discharge air. When the plastic film is wound, it passes through the bottom of the air outlet plate 31, and the air flow blown out by the air outlet plate 31 can blow and clean dust and other impurities on the surface of the plastic film, which is beneficial to the winding of the plastic film;

[0037] It should also be noted that when replacing the winding roller 12, the bottom rotating roller 25 and the top rotating roller 27 are used to squeeze and fix the plastic film. At this time, it is not necessary to turn off the air pump 33, thereby reducing the frequency and number of times of turning on and off the air pump 33, and improving the service life of the air pump 33.

[0038] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
