Description

Technical Field

[0001] This utility model relates to the field of film printing machine technology, and more specifically, to an electrostatic elimination mechanism for a film printing machine. Background Technology

[0002] Films are widely used in the electronics, machinery, and printing industries. Before use, films often need to have certain patterns or shapes printed on their surface. Film printing machines are commonly used equipment for film surface printing. When the film is guided by guide rollers in the film printing machine, it often generates static electricity through friction with the guide rollers. Static electricity can easily have an adverse effect on the film printing process and the quality of the film itself. Therefore, it is necessary to eliminate the static electricity generated between the film and the guide rollers.

[0003] Existing removal mechanisms address the issue that, due to the material properties of the film itself, copper brushes can easily scratch the film or leave marks on its surface during film printing and conveying, resulting in poor film printing quality.

[0004] A search revealed that Chinese Patent No. CN214563801U discloses an antistatic mechanism for a film printing machine. This utility model uses a conductive strip that contacts the film surface during the rotation of the guide roller. The static electricity carried on the film is conducted to a conductive component through the conductive strip. The conductive component then conducts the static electricity to the ground through a conductive rod and a first conductive clamp, thereby eliminating the static electricity on the film. This method ensures the quality of film conveying while facilitating the elimination of static electricity on the film surface.

[0005] However, in actual use, the above-mentioned static elimination mechanism will cause a lot of friction, peeling and squeezing between the film and the roller during the film winding process after the film printing is completed. This will cause static charges of different charges to accumulate on the surface of the object, which will affect the quality of the product. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electrostatic elimination mechanism for a film printing machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An electrostatic elimination mechanism for a film printing machine includes a base, on which the main body of the film printing machine is mounted. Multiple guide frames are fixedly connected to the top of the base. Two electrostatic elimination mechanisms are arranged on the outer side of the base. Each electrostatic elimination mechanism includes a servo motor, with a bevel gear fixedly connected to its output end. A bevel gear two meshes with one side of the bevel gear one. A rotating shaft is fixedly connected to the inner side of the bevel gear two. Both ends of the rotating shaft are fixedly connected to bevel gear three. A bevel gear four meshes with one side of the bevel gear three. A rotating rod is fixedly connected to the top of the bevel gear four. The outer side of the rotating rod is rotatably connected to the inner side of the base. Two threads are symmetrically arranged on the outer side of the rotating rod. A threaded slider is threadedly connected to the outer side of the threads. The outer side of the threaded slider is slidably connected to the inner side of the base and the guide frames. A fixed seat is fixedly connected to one side of the threaded slider. An electrostatic rod is fixedly connected to the top of the fixed seat. One end of the electrostatic rod is electrically connected to a wire. An auxiliary winding mechanism is arranged on the inner side of the base.

[0009] By adopting the above technical solution, two sets of electrostatic bars that can move in opposite directions on both sides of the base maintain an appropriate distance between the film during winding and unwinding, so that the film can be better eliminated from static electricity, thereby improving the static elimination filtration of the film and thus increasing the yield of the film.

[0010] As a further description of the above technical solution: the auxiliary winding mechanism includes multiple servo motors II. The outer side of each servo motor II is fixedly connected to the inner side of the base. A gear I is fixedly connected to the output end of each servo motor II. A gear II meshes with one side of the gear I. A locking rod is fixedly connected to one side of the gear II. A rotating roller is locked inside the locking rod. A collecting roller is fixedly connected to the outer side of the rotating roller. A bottom rod is fixedly connected to the inner side of the base. Two limiting frames are fixedly connected to the top of the bottom rod. A sliding frame is slidably connected to the inner side of the limiting frame. A pressure roller is rotatably connected to the top of the sliding frame. A limiting rod is slidably connected to the inner side of the bottom rod. The top of the limiting rod is fixedly connected to the bottom of the sliding frame. A spring is sleeved on the outer side of the limiting rod. The bottom of the spring is fixedly connected to the upper surface of the bottom rod.

[0011] By adopting the above technical solution, the pressure roller pushes the collecting roller, so that the air trapped between the films is squeezed out by the pressure roller during the winding process of the collecting roller, making the film winding smoother and avoiding wrinkles and other issues that would affect the quality of the product.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up an electrostatic elimination mechanism, compared with the existing technology, two sets of electrostatic bars are used to eliminate static electricity at both the unwinding and rewinding points of the film. Furthermore, by moving the opposing electrostatic bars up and down, the electrostatic bars can maintain a relatively suitable distance when the film conveying angle and height change, making the electrostatic elimination of the film more comprehensive and improving the yield of film printing.

[0014] 2. By setting up an auxiliary winding mechanism, compared with the existing technology, the air bubbles trapped between the films are squeezed out during the film winding process by using pressure rollers, so that the films are more flat and adhered to each other during the winding process, and the film is prevented from shifting or bending during the winding process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The embodiments disclosed in this application are as follows: Figure 1-6 The static elimination mechanism of a film printing machine shown includes a base 1, a film printing machine body 2 mounted on top of the base 1, multiple guide frames 3 fixedly connected to the top of the base 1, and two static elimination mechanisms arranged on the outer side of the base 1. Each static elimination mechanism includes a servo motor 4, a bevel gear 5 fixedly connected to the output end of the servo motor 4, a bevel gear 6 meshing on one side of the bevel gear 5, a rotating shaft 7 fixedly connected to the inner side of the bevel gear 6, bevel gears 8 fixedly connected to both ends of the rotating shaft 7, a bevel gear 9 meshing on one side of the bevel gear 8, a rotating rod 10 fixedly connected to the top of the bevel gear 9, the outer side of the rotating rod 10 rotatably connected to the inner side of the base 1, two threads 11 symmetrically arranged on the outer side of the rotating rod 10, and threaded sliders 12 threadedly connected to the outer side of the threads 11. The outer side of the slider 12 is slidably connected to the inner side of the base 1 and the guide frame 3. A fixed seat 13 is fixedly connected to one side of the threaded slider 12, and an electrostatic rod 14 is fixedly connected to the top of the fixed seat 13. One end of the electrostatic rod 14 is electrically connected to a wire 15. An auxiliary winding mechanism is provided inside the base 1. Two servo motors 1-4 drive bevel gear 1-5 to mesh with bevel gear 2-6 and rotating shaft 7, so that the rotating shaft 7 drives the corresponding two bevel gears 3-8 to rotate, so that bevel gear 3-8 can mesh with bevel gear 4-9, so that the two rotating rods 10 can perform opposing threaded transmission to the two threaded sliders 12 through the corresponding two sets of threads 11. The position of the two electrostatic rods 14 can be adjusted according to the different heights during the film winding and unwinding process, so that the electrostatic rods 14 can effectively eliminate static electricity from the film.

[0024] Reference Figure 3 , Figure 5 and Figure 6As shown, the auxiliary winding mechanism includes multiple servo motors 16. The outer side of each servo motor 16 is fixedly connected to the inner side of the base 1. A gear 17 is fixedly connected to the output end of each servo motor 16. A gear 18 meshes with one side of the gear 17. A locking rod 19 is fixedly connected to one side of the gear 18. A rotating roller 20 is locked inside the locking rod 19. A collecting roller 21 is fixedly connected to the outer side of the rotating roller 20. A base rod 22 is fixedly connected to the inner side of the base 1. Two limiting frames 23 are fixedly connected to the top of the base rod 22. A sliding frame 24 is slidably connected inside the limiting frames 23. A pressure roller 25 is rotatably connected to the top of the sliding frame 24. 2. A limiting rod 26 is slidably connected to the inner side. The top of the limiting rod 26 is fixedly connected to the bottom of the sliding frame 24. A spring 27 is sleeved on the outer side of the limiting rod 26. The bottom of the spring 27 is fixedly connected to the upper surface of the bottom rod 22. The locking rod 19 is used to lock the two ends of the rotating roller 20, so that the collecting roller 21 in the winding and unwinding can be removed from the inside of the base 1 for easy replacement. Then, the spring 27 pushes the limiting rod 26 to push the sliding frame 24 and the pressure roller 25, so that the pressure roller 25 can adhere and push the film being wound on the outside of the collecting roller 21, so that the film remains flat after winding and the film printing and winding maintains a good yield.

[0025] The working principle of this utility model is as follows: The film to be printed is rolled onto the outside of the collecting roller 21. Then, the two ends of the rotating roller 20 on the inner side of the collecting roller 21 are engaged with the two locking rods 19 on the inner side of the base 1. After that, one end of the film is passed through the film printing machine body 2 and then fixed to the collecting roller 21 on the other side of the base 1. Then, multiple sets of two servo motors 16 drive the corresponding gears 17 to mesh with gears 18, so that gears 18 can drive the two collecting rollers 21 to unwind and rewind. During the unwinding and rewinding of the film, the two servo motors... The first gear 4 drives the first bevel gear 5 and the second bevel gear 6 to rotate. The second bevel gear 6 drives the rotating shaft 7 and the two third bevel gears 8 to mesh with the fourth bevel gear 9 and the rotating rod 10. This causes the two rotating rods 10 to use the opposite threads on the outer sides to drive the corresponding two threaded sliders 12. This causes the corresponding two electrostatic bars 14 to move opposite to each other on the upper and lower sides of the film. This allows the electrostatic bars 14 to eliminate static electricity on the surface of the film. Furthermore, by using two sets of electrostatic bars 14 at the unwinding and rewinding points of the two collecting rollers 21, the film remains free of static electricity during the printing and rewinding process.

[0026] During the winding process, multiple springs 27 push the limiting rod 26 to support the top sliding frame 24 and pressure roller 25, allowing the pressure roller 25 to push the film during winding, reducing gaps in the film winding, and finally completing the static removal and winding of the film.
