Description

Technical Field

[0001] This utility model relates to the field of static electricity elimination technology, specifically a static electricity elimination device for the surface of an anti-fog film. Background Technology

[0002] Anti-fog films are generally made of polyester film, which is a thin film material made from polyethylene terephthalate (PET) through extrusion to form thick sheets, followed by biaxial stretching. An existing electrostatic elimination device for polyester film (publication number: CN222016835U) exhibits at least the following defects during use:

[0003] In the above scheme, the setting of the bidirectional lead screw and nut pair allows the rocker arm to be rotated according to the thickness of the polyester film to be eliminated. The rocker arm drives the bidirectional lead screw to rotate, the bidirectional lead screw drives the nut pair to move, the nut pair drives the moving block to move, the moving block drives the connecting rod to move, and the connecting rod drives the replacement component to move. This changes the spacing between the first antistatic cloths, making it convenient to eliminate static electricity on polyester films of different thicknesses. However, in actual use, an electric field is generated between the antistatic cloth and the static-laden film. The electric field force generated will pull the film, and the thin polyester film will deform under the action of the weak electric field force, hindering the subsequent processing and utilization of the film. Therefore, an anti-fog film surface static elimination device is needed. Utility Model Content

[0004] The main objective of this invention is to provide a device for eliminating static electricity on the surface of an anti-fog film, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An anti-fog film surface static electricity elimination device includes a support base. A driven lifting column is fixedly connected to the top of one side of the support base, and a rotating base column is fixedly connected to the top of the other end of the support base. Two active rotating shafts are rotatably connected to the top of the rotating base column. A lifting frame is respectively provided on the outer edge of the two active rotating shafts. A clamping base is provided between the two active rotating shafts. A bottom sliding plate and an elastic support block are fixedly connected to the opposite sides of the driven lifting column and the clamping base, respectively. A positioning clamp is fixedly connected to one end of each elastic support block.

[0007] Preferably, a pair of symmetrically distributed fixing seats are fixedly connected to both sides of the driven lifting column and the rotating base column. The opposite ends of each pair of fixing seats extend to the top of the corresponding positioning clamp, and an outer sleeve is fixedly connected to the top side of the opposite ends of each pair of fixing seats.

[0008] Preferably, a support spring is fixedly connected to the top inner wall of each outer sleeve, and a positioning post is fixedly connected to the bottom end of each support spring. Each positioning post passes through the corresponding fixing seat and contacts the top side of the corresponding positioning clamp.

[0009] Preferably, a traction rod is fixedly connected to the top side of each positioning column, and the top end of each traction rod is connected to a corresponding outer sleeve. A positioning slide frame is fixedly connected to the top end of each traction rod corresponding to the driven lifting column. A sliding top rod is slidably connected between the inner walls of all the positioning slide frames, and a fixed top rod is fixedly connected to the top end of the traction rods corresponding to the rotating base column.

[0010] Preferably, a positioning hook is fixedly connected to the side of the driven lifting column facing away from the rotating base column, and the top side of the positioning hook is adapted to the bottom side of the sliding top rod.

[0011] Preferably, each of the positioning clamps has multiple evenly distributed spherical slots on its bottom side, and a ball is provided between the inner walls of each spherical slot, with the outer edge of each ball contacting the corresponding bottom slide plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The device uses two lifting frames with internally installed anti-static cloth to remove static electricity from the film passing through them. At the same time, a support spring pushes an elastic support block toward the bottom slide plate, clamping the edges of the film about to enter the device. This prevents the film from stacking under the influence of the electric field, allowing the film to be processed in the next step while remaining flat. This eliminates the need for workers to rearrange the film and improves work efficiency. Attached Figure Description

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] An anti-fog film surface static elimination device includes a support base 107. A driven lifting column 101 is fixedly connected to the top of one side of the support base 107, and a rotating base column 106 is fixedly connected to the top of the other end of the support base 107. Two active rotating shafts 104 are rotatably connected to the top of the rotating base column 106. In this embodiment, the surfaces of the two active rotating shafts 104 are provided with helical grooves, and the two helical grooves are in opposite directions, so that the two active rotating shafts 104 form a bidirectional lead screw. A lifting frame 109 is respectively provided on the outer edge of the two active rotating shafts 104. Each lifting frame 109 is screwed to the corresponding active rotating shaft 104. A lifting slider 102 is fixedly connected to the other side of the lifting frame 109 and slidably connected to the driven lifting column 101. A clamping base is provided between the two active rotating shafts 104, and an active rotating handle 103 is connected to the top. Therefore, rotating the active rotating handle 103 controls the distance between the two lifting frames 109. A bottom slide plate 303 and an elastic support block 302 are fixedly connected to the opposite sides of the driven lifting column 101 and the clamping base, respectively. A positioning clamping plate 301 is fixedly connected to one end of each elastic support block 302.

[0024] A pair of symmetrically distributed fixed seats 204 are fixedly connected to both sides of the driven lifting column 101 and the rotating base column 106. The fixed seats 204 corresponding to the rotating base column 106 are fixedly connected to the rotating base column 106 through the support side frame 105. The opposite ends of each pair of fixed seats 204 extend to the top of the corresponding positioning clamp 301, and an outer sleeve 203 is fixedly connected to the top side of each pair of fixed seats 204. A support spring 202 is fixedly connected to the inner wall of the top side of each outer sleeve 203, and a positioning post 201 is fixedly connected to the bottom end of each support spring 202. Each positioning post 201 penetrates the corresponding fixed seat 204 and contacts the top side of the corresponding positioning clamp 301. Multiple evenly distributed spherical slots are opened on the bottom side of each positioning clamp 301. A ball bearing 304 is provided between the inner walls of each spherical slot, and the outer edge of each ball bearing 304 contacts the corresponding bottom slide plate 303. In this embodiment, the support spring 202 drives the positioning pin 201 to close the positioning clamp 301 and the bottom slide plate 303, clamping the film therein, which facilitates the static electricity removal process. The ball bearing 304 allows the film to pass smoothly through the positioning clamp 301 and the bottom slide plate 303, preventing the film from being torn during the traction process.

[0025] Each positioning column 201 has a traction rod 205 fixedly connected to its top side. The top end of each traction rod 205 is connected to a corresponding outer sleeve 203. A positioning slide frame 206 is fixedly connected to the top end of each traction rod 205 corresponding to the driven lifting column 101. A sliding top rod 207 is slidably connected between the inner walls of all positioning slide frames 206. A fixed top rod is fixedly connected to the top end of all traction rods 205 corresponding to the rotating base column 106. A positioning hook 208 is fixedly connected to the side of the driven lifting column 101 facing away from the rotating base column 106. The top side of the positioning hook 208 matches the bottom side of the sliding top rod 207. In this embodiment, when static elimination is not performed, the sliding top rod 207 is pulled onto the positioning hook 208, compressing the support spring 202, allowing the membrane to pass through.

[0026] It should be noted that this utility model is a static electricity elimination device for the surface of an anti-fog film. In use, the film is passed between two lifting frames 109. The lifting frames 109, which are equipped with static electricity elimination cloth 108 inside, perform static electricity elimination treatment on the film passing through them. At the same time, the support spring 202 pushes the elastic support block 302 to move closer to the bottom slide plate 303, clamping the two edges of the film about to enter the device, preventing the film from stacking under the action of electric field force. This allows the film to be processed in the next step while remaining flat, eliminating the need for workers to rearrange the film and improving work efficiency.
