Description

Technical Field

[0001] This utility model relates to an antistatic device, and more particularly to an antistatic device for label paper production applied in the field of label paper production and processing. Background Technology

[0002] Self-adhesive labels offer advantages over traditional labels, including no need for glue, paste, or water, zero pollution, and time-saving application. They are widely applicable, convenient, and quick to use. Self-adhesive labels are a composite material made of paper, film, or other special materials as the face stock, coated with adhesive on the back, and with silicone-coated release paper as the backing. After printing, die-cutting, and other processing, they become finished labels.

[0003] Chinese Patent Publication No. CN220292225U discloses an antistatic device and a printing press. This invention uses an antistatic eliminator electrically connected to a contact plate, which can abut against the printing screen. The antistatic eliminator absorbs static electricity. An adjustment mechanism adjusts the position of the contact plate so that it can abut against the printing screen. Through the cooperation of the antistatic mechanism and the adjustment mechanism, static electricity generated in the printing screen can be absorbed, and it can adapt to printing screens of different sizes, improving applicability.

[0004] However, the above patent still has the following problems in practical application: When using the above patent to prevent static electricity in label paper, it is necessary to contact the label paper through the contact plate to absorb the static electricity generated on the label paper. However, when the contact plate makes hard contact with the label paper, the contact plate may cause scratches on the surface of the label paper. Moreover, the contact plate, which needs to be manually adjusted, is prone to local indentation on the label paper due to uneven pressure, which will affect the production of the label paper. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the existing antistatic devices directly contact the label paper through the contact plate to conduct static electricity. However, the rigid contact plate may cause scratches and local indentations on the surface of the label paper during the movement process, thereby affecting the production of the label paper.

[0006] To address the aforementioned problems, this utility model provides an antistatic device for label paper production, comprising a support frame. Two U-shaped mounting rods are fixedly connected to the upper end of the support frame. A positioning plate is fixedly connected to the ends of the two mounting rods furthest from the support frame. An antistatic component is located below the positioning plate. Two adjusting screws are located at the lower end of the support frame. The upper ends of the adjusting screws thread through the support frame and are rotatably connected to a pressure plate. The antistatic component includes a compression spring fixedly connected to the lower end of the positioning plate. Two sliding rods, corresponding to the two compression springs respectively, are located at the upper end of the positioning plate. The lower ends of the sliding rods sequentially pass through the positioning plate and the compression springs and are fixedly connected to an L-shaped mounting plate. A rotating rod is located between the two mounting plates. Both ends of the rotating rod rotatably pass through adjacent mounting plates, and a rubber sleeve is fixedly fitted onto the outer surface of the rotating rod. Clamping heads are movably fitted onto both ends of the rotating rod. Multiple rollers are rotatably connected inside the clamping heads, and clamping plates are fixedly connected to the outer surface of the clamping heads. The clamping plates are fixedly connected to the mounting plates by bolts. Two static eliminators are placed at the upper end of the support frame, and conductive wires are fixedly connected between the static eliminators and adjacent clamping heads.

[0007] In the aforementioned antistatic device for label paper production, the contact piece is replaced with a rubber tube. The rubber tube contacts the surface of the label paper, and as the label paper moves, the rubber tube rotates, thereby introducing the static electricity on the surface of the label paper into the rotating rod. Then, the rotating rod, the card head, and the conductive wire introduce the static electricity into the static eliminator. During the rotation of the rubber tube, the floating structure composed of the rubber tube and the compression spring allows the rubber tube to adapt to label papers of different thicknesses, thereby effectively avoiding scratches and indentations on the surface of the label paper caused by uneven pressure and hard contact.

[0008] As a further improvement of this application, the ends of the two pressure plates that are far apart are both in contact with the longitudinal inner wall of the support frame, and the upper end of the pressure plates is provided with anti-slip texture.

[0009] As a further improvement of this application, multiple rollers are arranged in a circular array around the central axis of the chuck, and the outer surface of the rollers is in contact with the rotating rod.

[0010] As a further improvement of this application, the rubber tube is made of conductive silicone material, while the rotating rod, the clamp, and the roller are all made of metal material.

[0011] As another improvement of this application, the support frame includes a support plate and two U-shaped frames located at both ends of the support plate, with a pressure plate located inside the U-shaped frames and the surface of the pressure plate fitting against the inner wall of the U-shaped frames.

[0012] As a further improvement to this application, each of the two U-shaped frames has an extension screw fixedly connected to one end, and the two extension screws have threads that penetrate the support plate at one end.

[0013] In summary, in practical applications, pulling the two sliding rods upwards causes the compression spring to press upwards, moving the glue tube upwards. As the label paper moves, the outer surface of the glue tube comes into contact with the label paper, rotating as the label paper moves. This causes static electricity on the label paper surface to be introduced into the rotating rod, and then, along with the rotating rod, roller, card, and conductive wire, into the static eliminator, thus eliminating static electricity from the label paper surface. During the rotation of the glue tube, the floating structure composed of the glue tube and compression spring allows the glue tube to adapt to label papers of different thicknesses, effectively avoiding scratches and indentations on the label paper surface caused by uneven pressure and hard contact.

[0022] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] First implementation method:

[0024] Figure 1 , Figure 2 and Figure 3The diagram illustrates an antistatic device for label paper production, comprising a support frame 1. Two U-shaped mounting rods 2 are fixedly connected to the upper end of the support frame 1. A positioning plate 3 is fixedly connected to the ends of the two mounting rods 2 away from the support frame 1. An antistatic component is located below the positioning plate 3. Two adjusting screws 4 are located at the lower end of the support frame 1. The upper ends of the adjusting screws 4 are threaded through the support frame 1 and rotatably connected to pressure plates 5. The ends of the two pressure plates 5 that are far apart are in contact with the longitudinal inner wall of the support frame 1. The upper ends of the pressure plates 5 are provided with anti-slip textures. After the support frame 1 is inserted into the label paper production equipment, the height of the pressure plates 5 can be adjusted by rotating the adjusting screws 4, thereby limiting and fixing the production equipment and the support frame 1. The anti-slip textures effectively increase the friction between the pressure plates 5 and the production equipment, thus improving the stability of the support frame 1 during use.

[0025] Figure 1 , Figure 4 and Figure 5 The antistatic assembly includes a compression spring 6 fixedly connected to the lower end of the positioning plate 3. The upper end of the positioning plate 3 has two slide rods 7 corresponding to the two compression springs 6 respectively. The lower end of the slide rods 7 sequentially passes through the positioning plate 3 and the compression springs 6 and is fixedly connected to an L-shaped mounting plate 8. Moving the slide rods 7 upwards causes the compression springs 6 to contract upwards, driving the mounting plate 8 upwards, allowing the glue tube 10 to be used with label paper of different thicknesses. A rotating rod 9 is provided between the two mounting plates 8. Both ends of the rotating rod 9 rotate through the adjacent mounting plate 8, and the glue tube 10 is fixedly sleeved on the outer surface of the rotating rod 9. The glue tube 10 is made of conductive silicone material, allowing it to discharge static electricity from the label paper surface. Both ends of the rotating rod 9 are movably sleeved with clips 11, and multiple rollers are rotatably connected inside the clips 11. 12. Multiple rollers 12 are arranged in a circular array around the central axis of the card head 11, and the outer surface of the rollers 12 is in contact with the rotating rod 9. The rotating rod 9, the card head 11, and the rollers 12 are all made of metal. The outer surface of the card head 11 is fixedly connected to the card plate 13, and the card plate 13 is fixedly connected to the mounting plate 8 by bolts. Two static eliminators 14 are placed at the upper end of the support frame 1. Those skilled in the art can select a suitable model of static eliminator 14 according to actual needs, such as JH5008B. The static eliminator 14 is fixedly connected to the adjacent card head 11 by a conductive wire 15. The static electricity on the surface of the label paper is introduced into the rotating rod 9, and then introduced into the static eliminator 14 along with the rotating rod 9, rollers 12, card head 11, and conductive wire 15, thereby eliminating static electricity on the surface of the label paper.

[0026] In use, the support frame 1 is clamped above the label paper production equipment. Then, by rotating the adjusting screw 4, the pressure plate 5 moves up and down, thereby limiting and fixing the support frame 1. Pulling the two sliding rods 7 upward causes the compression spring 6 to press upward, and the glue tube 10 moves upward. When the label paper moves, the outer surface of the glue tube 10 comes into contact with the label paper and rotates as the label paper moves, thereby introducing the static electricity on the surface of the label paper into the rotating rod 9. Then, along with the rotating rod 9, roller 12, clamp head 11, and conductive wire 15, the static electricity is introduced into the static eliminator 14, thereby eliminating static electricity on the surface of the label paper. During the rotation of the glue tube 10, the floating structure composed of the glue tube 10 and the compression spring 6 allows the glue tube 10 to adapt to label papers of different thicknesses, thereby effectively avoiding scratches and indentations on the surface of the label paper caused by uneven pressure and hard contact.

[0027] Second implementation method:

[0028] This embodiment adds a support plate 101, a U-shaped frame 102, and an extension screw 103 to the first embodiment, while the rest remains the same as the first embodiment.

[0029] Figure 6 As shown: the support frame 1 includes a support plate 101 and two U-shaped frames 102 located at both ends of the support plate 101. The pressure plate 5 is located inside the U-shaped frame 102, and the surface of the pressure plate 5 is in contact with the inner wall of the U-shaped frame 102. An extension screw 103 is fixedly connected to one end of each of the two U-shaped frames 102, and the corresponding ends of the two extension screws 103 are threaded through the support plate 101.

[0030] When the support frame 1 is installed with the label paper production equipment, the extension screw 103 can be screwed out by rotating the U-shaped frame 102, thereby extending the U-shaped frame 102 outward. This allows the support frame 1 to be applicable to different label paper production equipment, eliminating static electricity on the label paper in different processes, thereby improving the practicality of this application.

[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
