Description

Technical Field

[0001] This utility model relates to an antistatic device, specifically an antistatic device for hot melt adhesive film, belonging to the field of hot melt adhesive film technology. Background Technology

[0002] Hot melt adhesive film is a thin film material made of thermoplastic polymers. It typically becomes viscous when heated and solidifies upon cooling. Its main components include polyethylene, polypropylene, and polyurethane, which can flow when heated and form strong bonds with other materials.

[0003] A search revealed a Chinese patent (CN212677434U) disclosing a static eliminator for hot melt adhesive film. The device includes a base plate, a right-side support fixedly mounted on the top right side of the base plate, an unwinding roller movably mounted inside the right-side support, a support rod fixedly mounted on the top of the base plate, a top plate fixedly mounted on the top of the support rod, an installation assembly fixedly mounted on the bottom of the top plate, a back plate fixedly mounted on the back of the base plate, and a power supply component fixedly mounted on the front of the back plate. An antistatic rod is movably connected to the outer wall of the installation assembly. This hot melt adhesive film static eliminator, by setting an unwinding roller and a rewinding roller, and simultaneously fixing a limit rod on the top of the base plate, incorporates a through groove inside the limit rod for the hot melt adhesive film to pass through for positional calibration. When the motor assembly drives the first transmission wheel to rotate, its transmission belt drives the second transmission wheel to rotate simultaneously.

[0004] While the above solutions can calibrate the position of the hot melt adhesive film, the aforementioned patents are difficult to adapt to rollers of different lengths. Because the width of the hot melt adhesive film varies, rollers of different lengths are required for winding. However, the platform position of the aforementioned patents is fixed, and they can only be used for rollers of a single length, which is quite limiting and reduces the practical effect. To address this, we provide a hot melt adhesive film antistatic device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a hot melt adhesive film antistatic device to solve the above-mentioned problems, thereby addressing the difficulty in adapting to rollers of different lengths in the prior art.

The linkage swing arm is slidably connected to the inner wall of the main control housing, and a frame body is fixedly connected to the top of the linkage swing arm. The close fit between the components allows this application to adapt to rollers of different lengths.

[0007] Preferably, the frame body is rotatably connected to a U-shaped control frame, which is threadedly connected to the frame body via positioning bolts. The frame body is mainly used for the installation and use of the roller body.

[0008] Preferably, there are two main control housings, both of which are fixedly connected to the upper surface of the main mounting base plate. The main mounting base plate is provided with bolt holes, which facilitates the installation and fixing of the main mounting base plate.

[0009] Preferably, a support base is fixedly connected to the upper surface of the main mounting base plate. There are two support bases in total. The setting of the support bases ensures the stability of the U-shaped frame.

[0021] This utility model provides a device for removing static electricity from hot melt adhesive film.

[0022] Please see Figure 1 It includes a main control housing 1 and a roller body 2. There are two roller bodies 2 in total. The two roller bodies 2 are used to wind up the hot melt adhesive film and unwind the hot melt adhesive film respectively, so that the hot melt adhesive film can pass between two antistatic bars 15, which is beneficial for subsequent antistatic operations on the hot melt adhesive film.

[0023] Please see Figure 1 There are two main control housings 1. Both main control housings 1 are fixedly connected to the upper surface of the main mounting base plate 10. The purpose of setting the main mounting base plate 10 is to effectively ensure the stability of the two main control housings 1, so that the two main control housings 1 will not shift, thereby ensuring the stable operation of subsequent components.

[0024] Please see Figure 1 The upper surface of the main mounting base plate 10 is fixedly connected to a support base 12. There are two support bases 12 in total. The top of the two support bases 12 is fixedly connected to a U-shaped frame 13. The purpose of setting the support bases 12 is to effectively support the U-shaped frame 13 and ensure the stability of the U-shaped frame 13 during the support process.

[0025] Please see Figure 1 An antistatic rod 15 is rotatably connected to the inner wall of the U-shaped frame 13. The purpose of the U-shaped frame 13 is to support and control the antistatic rod 15, thereby ensuring that the antistatic rod 15 can rotate in place within the U-shaped frame 13 without any displacement.

[0026] Please see Figure 1There are two antistatic rods 15. The purpose of setting two antistatic rods 15 is to effectively remove static electricity from the upper and lower sides of the hot melt adhesive film by placing them on the upper and lower sides of the film. The antistatic rods 15 generate high voltage through a high voltage generator, which induces corona discharge at the sharp electrode tip, ionizing the air into positive and negative ions. These ions diffuse to the working area under the impetus of electric field force, convection or airflow, actively seeking out and neutralizing opposite charges on the surface of nearby charged objects, thereby quickly and effectively eliminating static electricity from the hot melt adhesive film. The antistatic rods 15 are existing known technology, and this application will not elaborate further on the antistatic rods 15.

[0027] Please see Figure 1 A battery pack 14 is fixedly connected to the top of the U-shaped frame 13. The purpose of setting the battery pack 14 is to provide high voltage energy to the antistatic rod 15 in this application, so that the antistatic rod 15 can work stably. The battery pack 14 and the antistatic rod 15 are electrically connected. The battery pack 14 is the prior art, and this application will not describe the battery pack 14 in detail.

[0028] Please see Figure 1 The main mounting base plate 10 has bolt holes 11. The purpose of setting bolt holes 11 is to facilitate the staff to quickly and securely install the device of this application in the designated position according to actual needs.

[0029] Please see Figure 2 and Figure 3 A DC motor 3 is fixedly connected to the top of the main control housing 1. The output shaft of the DC motor 3 is fixedly connected to the power swing arm 4. The purpose of setting the DC motor 3 is to effectively provide sufficient power support for the rotation of the power swing arm 4. The DC motor 3 is existing publicly available technology, and this application will not elaborate on the model of the DC motor 3.

[0030] Please see Figure 3 One end of the power swing rod 4 is rotatably connected to the linkage swing rod 5, and one end of the linkage swing rod 5 is rotatably connected to the linkage slide plate 6. The close cooperation between the power swing rod 4, the linkage swing rod 5 and the linkage slide plate 6 means that when the linkage slide plate 6 is restricted, the rotation of the power swing rod 4 can drive the linkage slide plate 6 to translate through the linkage swing rod 5. Furthermore, through the design of the same components, the two linkage slide plates 6 can move in opposite directions.

[0031] Please see Figure 2 and Figure 3The linkage slide plate 6 is slidably connected to the inner wall of the main control housing 1. The purpose of setting the main control housing 1 is to effectively apply a control effect to the linkage slide plate 6, ensuring that the linkage slide plate 6 can only move horizontally within the linkage slide plate 6. At the same time, it can provide protection for the internal components of the main control housing 1, so that the internal components of the main control housing 1 are protected from external interference.

[0032] Please see Figure 1 , Figure 3 and Figure 4 The top of the linkage slide plate 6 is fixedly connected to the frame body 7. The linkage slide plate 6 and the frame body 7 are directly connected and maintain the linkage effect. The purpose of setting the frame body 7 is mainly for the installation of the roller body 2, ensuring that the roller body 2 can rotate in place. The frame body 7 is rotatably connected to the U-shaped control frame 8. The purpose of setting the U-shaped control frame 8 is to achieve the effect of quick assembly and disassembly of the roller body 2. The U-shaped control frame 8 is threadedly connected to the frame body 7 through the positioning bolt 9. The setting of the positioning bolt 9 facilitates the reinforcement of the U-shaped control frame 8 and ensures the stability of the U-shaped control frame 8.

[0033] Working principle: In use, a roller body 2 of appropriate length can be selected according to the width of the hot melt adhesive film. Simply start the DC motor 3 to drive the power swing arm 4 to rotate in place. At this time, because the linkage slide plate 6, which is connected to the linkage swing arm 5, is restricted by the main control housing 1, the power swing arm 4 can drive the linkage slide plate 6 to move horizontally within the main control housing 1 via the linkage swing arm 5. Due to the design of identical components, the two linkage slide plates 6 move relative to each other within the main control housing 1. The linkage slide plate 6 will drive the frame body 7 to shift, thereby changing the position of the two slide plates. The spacing between the main frame 7 facilitates the installation of the roller body 2. During installation, simply place the two ends of the roller body 2 on the two main frame 7, then manually close the U-shaped control frame 8, and tighten the positioning bolts 9 to complete the installation of the roller body 2, achieving the purpose of quick installation of the roller body 2. Finally, simply pass the hot melt adhesive film between the two antistatic bars 15, start the battery pack 14 to provide power to the antistatic bars 15, and as the roller body 2 rotates, the hot melt adhesive film moves continuously, thereby removing static electricity from both sides of the hot melt adhesive film surface.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
