Description
Technical Field
[0001] This utility model relates to the field of printing processing technology, specifically to a double-sided electrostatic elimination film guiding mechanism for a pre-coated laminating machine. Background Technology
[0002] A laminating machine is a device that bonds a film to the surface of an object by hot or cold pressing. It is widely used in many industries to provide surface protection and aesthetic enhancement.
[0003] Currently, invention patent CN111483221B discloses a pre-coated laminating machine for printing, including a machine body, a film feeding roller, a tension roller group, a hot press roller group, a re-press roller group, and a conveyor table. The film feeding roller and the tension roller group are fixedly installed above the machine body. The hot press roller group and the re-press roller group are arranged inside the machine body. The conveyor table is fixedly installed on the side of the machine body. A preheating mechanism for generating heat through friction is fixedly installed above the machine body, located below the tension roller group. This pre-coated laminating machine for printing converts kinetic energy into heat energy through the sliding friction between the preheating mechanism and the film, increasing the surface temperature of the film, promoting the melting of the adhesive on the film, reducing uneven melting of the film caused by insufficient contact time between the film and the hot press roller group, improving the uniformity of adhesive melting, and contributing to the firmness of the bonding between the printed matter and the film. It solves the problem of film separation between the printed matter and the film, and improves the quality of printing lamination.
[0004] In existing laminating machines, the film surface comes into contact with air during the film conveying process. The air contains dust, and the guide rollers generate static electricity under the action of friction when guiding the film. The dust in the air will be attracted to the film under the action of static electricity, which will affect the laminating quality. To solve the above problems, this application proposes a double-sided static electricity elimination film guiding mechanism for a pre-coated laminating machine. Utility Model Content
[0005] (I) Purpose of the utility model
[0006] To address the technical problems existing in the background art, this utility model proposes a double-sided electrostatic elimination film guiding mechanism for a pre-coated laminating machine. An air filter element filters dust from the air to ensure air cleanliness. When air passes through an ion fan, positive and negative ions are generated through ionization and transported to the upper and lower surfaces of the film. The ion wind neutralizes the static electricity on the film surface, achieving electrostatic elimination on both sides of the film. After electrostatic elimination, dust adhesion to the film surface is reduced during transport, thus improving laminating quality and solving the problems mentioned in the background art.
[0007] (II) Technical Solution
[0008] To solve the above-mentioned technical problems, this utility model provides a double-sided static elimination film guiding mechanism for a pre-coated laminating machine, including a laminating machine body, a film unwinding roller, a film guide roller, a paper roll unwinding roller, a winding roller, and a laminating roller. The laminating machine body is provided with an upper static elimination cover and a lower static elimination cover, with the upper static elimination cover located above the lower static elimination cover.
[0009] Both the upper and lower static eliminators are equipped with ion fans inside their cavities.
[0010] An air pump is installed on the side wall surface of the film-coating machine. The air outlet of the air pump is connected to the upper static eliminator and the lower static eliminator respectively through an air guide pipe.
[0011] An air filter element is installed on the suction end surface of the air pump.
[0012] Preferably, a film unwinding roller is rotatably mounted on one end of the film coating machine body, and a film roll is provided on the film unwinding roller.
[0013] Preferably, a film guide roller is provided above the film unwinding roller, and the film guide roller is used to guide the film.
[0014] Preferably, a paper roll unwinding roller is installed at the other end of the laminating machine body, and a take-up roller is rotatably installed below the paper roll unwinding roller.
[0015] Preferably, a pressure roller is provided between the take-up roller and the unwind roller, and the paper and film pass through the pressure roller.
[0016] Preferably, an exhaust hood is installed on the side wall surface of the film coating machine body, an exhaust fan is installed on the surface of the exhaust hood, and exhaust ports are provided on the side walls of the upper and lower static elimination hoods. The exhaust hood and the exhaust ports are connected by an air guide pipe.
[0017] Preferably, both the upper and lower static eliminator covers are provided with rubber frames.
[0018] The above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0019] 1. In this utility model, during the conveying process of the film, the air pump injects outside air into the upper and lower static eliminator hoods through the air guide pipe. The air pump is equipped with an air filter element at its suction end. The air filter element can filter dust in the air to ensure air cleanliness. When the air passes through the ion fan, positive and negative ions are generated by ionization of the air and transported to the upper and lower surfaces of the film. The static electricity on the film surface is neutralized by the ion wind, realizing static elimination on both sides of the film. After the static electricity on the film surface is eliminated, dust can be reduced to adhere to the film surface during the conveying process, thereby improving the coating quality.
[0020] 2. In this utility model, the surfaces of the upper and lower static eliminator are attached to the two sides of the film through a rubber frame, which can reduce the leakage of ion air during the film conveying process. Then, the exhaust fan extracts the ion air from the upper and lower static eliminator, which can prevent the airflow from causing the film to sway when static electricity is eliminated on the film surface, thus ensuring the coating accuracy.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0028] like Figure 1-4 As shown, the present invention proposes a double-sided static elimination film guiding mechanism for a pre-coated laminating machine, comprising a laminating machine body 1, a film unwinding roller 2, a film guide roller 3, a paper roll unwinding roller 4, a winding roller 5, and a laminating roller 6. The laminating machine body 1 is provided with an upper static elimination cover 7 and a lower static elimination cover 8 in its inner cavity, with the upper static elimination cover 7 located above the lower static elimination cover 8.
[0029] Both the upper static eliminator 7 and the lower static eliminator 8 are equipped with ion fans 9.
[0030] An air pump 10 is installed on the side wall surface of the film-coating machine body 1. The air outlet of the air pump 10 is connected to the upper static eliminator 7 and the lower static eliminator 8 respectively through an air guide pipe.
[0031] An air filter element 11 is installed on the suction end surface of the air pump 10.
[0032] It should be noted that during the film transport process, the air pump 10 injects outside air into the upper static eliminator 7 and the lower static eliminator 8 through the air guide pipe. The air pump 10 is equipped with an air filter 11 at its suction end. The air filter 11 can filter dust in the air to ensure air cleanliness. When the air passes through the ion fan 9, positive and negative ions are generated by ionization and transported to the upper and lower surfaces of the film. The static electricity on the film surface is neutralized by the ion wind, realizing static elimination on both sides of the film. After the static electricity on the film surface is eliminated, dust can be reduced from adhering to the film surface during transport, thereby improving the coating quality.
[0033] In this embodiment, as Figure 1 As shown, a film unwinding roller 2 is rotatably mounted on one end of the laminating machine body 1. A film roll is provided on the film unwinding roller 2. A film guide roller 3 is provided above the film unwinding roller 2. The film guide roller 3 is used to guide the film. A paper roll unwinding roller 4 is mounted on the other end of the laminating machine body 1. A take-up roller 5 is rotatably mounted below the paper roll unwinding roller 4. A covering roller 6 is provided between the take-up roller 5 and the paper roll unwinding roller 4, and the paper and film pass through the covering roller 6.
[0034] It should be noted that the paper roll and the film roll are fixed on the paper roll unwinding roller 4 and the film unwinding roller 2, respectively. The film is guided by the film guide roller 3 and passes between the upper static elimination cover 7 and the lower static elimination cover 8. After the film and paper are covered by the covering roller 6, they are wound up by the winding roller 5.
[0035] In this embodiment, as Figure 3 As shown, an exhaust hood 13 is installed on the side wall surface of the film coating machine body 1, and an exhaust fan 14 is installed on the surface of the exhaust hood 13. The side walls of the upper static elimination hood 7 and the lower static elimination hood 8 are both provided with exhaust ports 12, and the exhaust hood 13 and the exhaust ports 12 are connected by an air guide pipe.
[0036] It should be noted that the exhaust port 12 is connected to the exhaust hood 13 through a pipe, and the exhaust fan 14 draws out the ion air in the upper static elimination hood 7 and the lower static elimination hood 8, which can prevent the airflow from causing the film to sway when static electricity is eliminated on the film surface, so as to ensure the coating accuracy.
[0037] In this embodiment, as Figure 4As shown, both the upper static eliminator 7 and the lower static eliminator 8 are provided with rubber frames 15.
[0038] It should be noted that the surfaces of the upper static eliminator 7 and the lower static eliminator 8 are bonded to the two sides of the film through the rubber frame 15, which can reduce the leakage of ion wind during the film conveying process.
[0039] The working principle and usage process of this utility model are as follows: The paper roll and the film roll are respectively fixed on the paper roll unwinding roller 4 and the film unwinding roller 2. The film is guided by the film guide roller 3 and passes between the upper static elimination cover 7 and the lower static elimination cover 8. After the film and paper are covered by the covering roller 6, they are wound up by the winding roller 5. During the film conveying process, the air pump 10 injects outside air into the upper static elimination cover 7 and the lower static elimination cover 8 through the air guide pipe. The air pump 10 is equipped with an air filter element 11 at the air intake end. The air filter element 11 can filter dust in the air to ensure the cleanliness of the air. When the air passes through the ion fan 9, positive and negative ions are generated by ionization of the air and transported to the upper part of the film. On the lower surface, static electricity on the film surface is neutralized by ion wind, achieving static elimination on both sides of the film. After static elimination, dust adhesion to the film surface is reduced during transportation, thus improving the coating quality. Both the upper static elimination hood 7 and the lower static elimination hood 8 have exhaust ports 12 on their side walls. The exhaust ports 12 are connected to the exhaust hood 13 through pipes. The surfaces of the upper static elimination hood 7 and the lower static elimination hood 8 are attached to the two sides of the film through rubber frames 15, which reduces the leakage of ion wind during film transportation. The exhaust fan 14 then extracts the ion wind from the upper static elimination hood 7 and the lower static elimination hood 8, which can prevent the airflow from causing the film to sway during static elimination on the film surface, thus ensuring coating accuracy.
