Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular to a winding equipment for producing high-transparency, high-UV-blocking EVA film. Background Technology

[0002] Optical lens inspection is used to inspect the components of optical lenses. Depending on the overall inspection requirements, the inspection methods for optical lenses vary, including the need to inspect the appearance of the optical lenses.

[0003] Utility model patent CN206447358U discloses an automatic EVA film winding device. This device includes a frame, on which a slotted roller, guide roller, friction roller, winding shaft, and finished product shaft seat are sequentially arranged. A spare shaft is mounted on the frame above the friction roller. An antistatic bar for removing static electricity from the EVA film is located between the guide roller and the friction roller, positioned above the EVA film. An antistatic bar for generating static electricity in the EVA film is located in front of the winding shaft. A cutter assembly is mounted on the frame to cut the EVA film between the spare shaft and the winding shaft. This utility model has a simple structure. With the addition of an electrostatic adsorption device, the cutter generates a small amount of static electricity in the EVA film while cutting it, causing it to adhere tightly to the paper core of the spare shaft. During winding, the film does not wrinkle, resulting in a smooth appearance. Simultaneously, the antistatic device prevents static electricity buildup in the film assembly during later use, improving the efficiency and lifespan of the solar panel.

[0004] However, the device has certain shortcomings in use. It lacks guidance during the winding process of films with different widths, resulting in uneven edges after winding. At the same time, the device is prone to causing the film to be wound too loosely during the winding process. Utility Model Content

[0005] This invention provides a winding device for producing high-transparency, high-UV-blocking EVA film, which solves the problems of lack of guidance during the winding process of films of different widths, resulting in uneven edges after winding, and the film winding process being prone to loosening due to insufficient tightness.

[0006] To solve the above-mentioned technical problems, this utility model provides a winding device for producing high-transparency, high-UV-blocking EVA film, including a base plate, a side plate fixedly connected to the upper end of the base plate, a winding roller rotatably connected inside the side plate, a motor fixedly installed at the front end of the side plate, the motor shaft passing through the side plate and rotatably connected to the side plate, the motor shaft being fixedly connected to the winding roller, a bracket fixedly connected to the upper end of the base plate, a guide mechanism being provided on the bracket, a tensioning mechanism being provided on the bracket, and a pressure roller being provided on the tensioning mechanism.

[0007] Preferably, the guiding mechanism includes a support cylinder that contacts the pressure roller. A bidirectional screw is rotatably connected inside the support cylinder, and a sliding plate is movably connected to the outer side of the bidirectional screw. The sliding plate is slidably connected to the support cylinder, and a limit ring is slidably connected to the outer side of the support cylinder. A screw disc is threadedly connected to the outer side of the bidirectional screw, and the screw disc is slidably connected to the support cylinder. A pull rod is fixedly connected to the surface of the sliding plate, and the pull rod is slidably connected to the screw disc. A compression spring is provided on the outer side of the pull rod. By rotating the bidirectional screw and the screw disc in a threaded motion, the compression spring drives the pull rod to move, which in turn causes the sliding plate to drive the limit ring to move. This allows the device to guide and limit films of different widths, resulting in neater edges on the wound film.

[0008] Preferably, a sliding rod is fixedly connected to the surface of the limiting ring, the sliding rod is slidably connected to the support cylinder, and the sliding rod is fixedly connected to the sliding plate. By setting the sliding rod, the sliding plate can drive the limiting ring to move.

[0009] Preferably, one end of the compression spring is fixedly connected to the pull rod, and the other end of the compression spring is fixedly connected to the screw disc. By setting the compression spring, the pull rod is elastically compressed.

[0010] Preferably, the tensioning mechanism includes a screw, which is mounted inside the bracket via a bearing. A screw cylinder is threadedly connected to the outside of the screw, and a slide cylinder is slidably connected to the outside of the screw cylinder. A support is fixedly connected to the lower end of the slide cylinder, and the support is rotatably connected to the pressure roller. A spring is installed inside the slide cylinder. By rotating the screw and screw cylinder to perform threaded movement, the spring elastically compresses the support, which in turn causes the support to elastically press the pressure roller down, thereby elastically pressing the film against the support cylinder. This ensures that the film is tensioned during winding, preventing it from loosening.

[0011] Preferably, a sliding pin is slidably connected to the outer side of the screw barrel, and the sliding pin and the slide barrel are slidably connected. By providing the sliding pin, relative rotation between the screw barrel and the slide barrel is prevented.

[0012] Preferably, one end of the spring is fixedly connected to the screw cylinder, and the other end of the spring is fixedly connected to the support. By setting the spring, the support is elastically compressed.

[0013] Compared with related technologies, the winding equipment for producing high-transparency, high-UV-blocking EVA film provided by this utility model has the following beneficial effects: This invention provides a winding device for producing high-transparency, high-UV-blocking EVA film. By rotating a bidirectional screw and a screw disc to make a spiral motion, the compression spring drives the pull rod to move, which in turn drives the sliding plate to move the limiting ring. This allows the device to limit and guide films of different widths, resulting in neater edges on the wound film.

[0014] This utility model provides a winding device for producing high-transparency, high-UV-blocking EVA film. By rotating the screw and the screw cylinder to make a spiral motion, the spring elastically squeezes the support, which in turn causes the support to elastically press the pressure roller down, thereby pressing the film elastically onto the support cylinder. This ensures that the film is tensioned during the winding process and is less likely to loosen. Attached Figure Description

[0017] Please see Figures 1-2 A winding device for producing high-transparency, high-UV-blocking EVA film includes a base plate 1, a side plate 2 fixedly connected to the upper end of the base plate 1, a winding roller 3 rotatably connected inside the side plate 2, a motor 4 fixedly installed at the front end of the side plate 2, the rotating shaft of the motor 4 passing through the side plate 2 and rotatably connected to the side plate 2, the rotating shaft of the motor 4 being fixedly connected to the winding roller 3, a bracket 5 fixedly connected to the upper end of the base plate 1, a guide mechanism 6 provided on the bracket 5, a tensioning mechanism 7 provided on the bracket 5, and a pressure roller 8 provided on the tensioning mechanism 7.

[0018] Please see Figure 1 , Figure 2 , Figure 3The guide mechanism 6 includes a support cylinder 61, which contacts the pressure roller 8. A bidirectional screw 62 is rotatably connected inside the support cylinder 61. A sliding plate 63 is movably connected to the outer side of the bidirectional screw 62, and the sliding plate 63 is slidably connected to the support cylinder 61. A limit ring 64 is slidably connected to the outer side of the support cylinder 61. A sliding rod 65 is fixedly connected to the surface of the limit ring 64, and the sliding rod 65 is slidably connected to the support cylinder 61 and fixedly connected to the sliding plate 63. By setting the sliding rod 65, the sliding plate 63 can drive the limit ring 64 to move. A screw disc 66 is threadedly connected to the outer side of the bidirectional screw 62, and the screw disc 66 is connected to the support cylinder. A sliding connection is provided. A pull rod 67 is fixedly connected to the surface of the slide plate 63. The pull rod 67 and the screw plate 66 are slidably connected. A compression spring 68 is provided on the outside of the pull rod 67. One end of the compression spring 68 is fixedly connected to the pull rod 67, and the other end of the compression spring 68 is fixedly connected to the screw plate 66. By setting the compression spring 68, the pull rod 67 is elastically compressed. By rotating the bidirectional screw 62 and the screw plate 66 to make threaded movement, the compression spring 68 drives the pull rod 67 to move, which in turn causes the slide plate 63 to drive the limiting ring 64 to move. This allows the device to limit and guide films of different widths, making the edges of the wound film neater.

[0019] Please see Figure 1 , Figure 4 The tensioning mechanism 7 includes a screw 71. The screw 71 is mounted inside the bracket 5 via bearings. A screw cylinder 72 is threadedly connected to the outside of the screw 71. A slide cylinder 73 is slidably connected to the outside of the screw cylinder 72. A sliding pin 74 is slidably connected to the outside of the screw cylinder 72. The sliding pin 74 and the slide cylinder 73 are slidably connected. By setting the sliding pin 74, relative rotation between the screw cylinder 72 and the slide cylinder 73 is prevented. A support 75 is fixedly connected to the lower end of the slide cylinder 73. The support 75 is rotatably connected to the pressure roller 8. An internal spring 76 is provided. One end of the spring 76 is fixedly connected to the screw cylinder 72, and the other end of the spring 76 is fixedly connected to the support 75. By setting the spring 76, the support 75 is elastically compressed. By rotating the screw 71 and the screw cylinder 72 to make threaded movement, the spring 76 elastically compresses the support 75, which in turn causes the support 75 to elastically press the pressure roller 8 down, thereby making the film elastically pressed onto the support cylinder 61. This ensures that the film is tensioned during the winding process and is less likely to loosen.

[0020] Working principle: In use, one end of the film is passed between the pressure roller 8 and the support cylinder 61 and fixed to the winding roller 3. The bidirectional screw 62 is manually rotated, and the rotation of the bidirectional screw 62 and the screw disc 66 make a threaded movement, which in turn causes the screw disc 66 to move. The movement of the screw disc 66 compresses the pressure spring 68, which in turn causes the pressure spring 68 to drive the pull rod 67 to move, which in turn causes the pull rod 67 to drive the slide plate 63 to move, which in turn causes the slide plate 63 to drive the limiting ring 64 to move. This allows the device to limit and guide films of different widths, making the edges of the wound film neater. During the winding process, the screw 71 is manually rotated, and the rotation of the screw 71 and the screw cylinder 72 make a threaded movement, which in turn causes the spring 76 to elastically compress the support 75, which in turn causes the support 75 to elastically press down the pressure roller 8, which in turn causes the film to be elastically pressed onto the support cylinder 61, thus keeping the film taut during the winding process and preventing it from loosening.
