Description

Technical Field

[0001] This utility model belongs to the field of laminating machine technology, specifically relating to a fully automatic laminating machine. Background Technology

[0002] Laminating machines can be broadly classified into two categories: in-line laminating machines and pre-coated laminating machines. They are specialized equipment used for laminating paper and board materials. After being pressed together by rubber rollers and heated rollers, they form a paper-plastic composite product. This equipment is used to complete the lamination process. Generally, based on the process used, they can be divided into in-line coating and pre-coated film; based on the different film materials, they can be divided into glossy film and matte film. In the process of producing laminated paper, a laminating machine is needed to apply a film to the surface of the paper, thereby improving the paper's gloss and durability.

[0003] Chinese Patent CN220146684U discloses a fully automatic laminating machine, including a base, a conveying unit, a flattening unit, and an unwinding unit for unwinding the film body.

[0004] Regarding the aforementioned related technologies, the inventors have discovered at least the following problems: when paper is conveyed via a conveyor belt, the paper is prone to shifting on the conveyor belt, resulting in a decrease in lamination quality. Furthermore, dust easily adheres to the paper surface, which also affects the lamination quality. Utility Model Content

[0005] The purpose of this invention is to provide a fully automatic laminating machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic laminating machine, comprising a frame, a guiding mechanism, and a dust removal mechanism. A conveyor belt is rotatably mounted on the frame, and a feeding roller and a receiving roller are rotatably mounted at both ends of the frame, respectively. A laminating box is fixedly mounted on the frame between the feeding roller and the receiving roller. The guiding mechanism is located on the side of the laminating box near the feeding roller, and the dust removal mechanism is located inside the laminating box on the side near the feeding roller.

[0007] The guiding mechanism includes two guide plates symmetrically arranged on the outer wall of the film-coating box and a driving component for adjusting the distance between the two guide plates. A cylinder is fixedly installed on the side of the two guide plates that are close to each other. A connecting block is fixedly connected to the piston end of the cylinder, and a pressure roller is rotatably installed on one side of the connecting block.

[0008] The dust removal mechanism includes an electric push rod fixedly installed on the top wall inside the laminating box, a housing fixedly connected to the lower end of the electric push rod, and a cleaning roller rotatably installed inside the housing. A scraper is fixedly connected to the bottom of the housing near the cleaning roller. A dust suction hood with an opening facing the cleaning roller is fixedly connected inside the housing. A vacuum cleaner is fixedly installed on the top of the laminating box, and the inlet of the vacuum cleaner is connected to the dust suction hood.

[0009] In a preferred embodiment, the driving component includes a bidirectional screw rotatably mounted on the outer wall of the coating box and a motor for driving the bidirectional screw to rotate. The two guide plates are respectively sleeved on both ends of the bidirectional screw and threadedly connected to the bidirectional screw.

[0010] In a preferred embodiment, a guide rod parallel to the bidirectional screw is fixedly installed on the outer wall of the film-coating box, and the guide plate is slidably sleeved on the guide rod.

[0011] In a preferred embodiment, a limiting groove is formed on the surface of the guide plate, and one end of the connecting block slides within the limiting groove.

[0012] In a preferred embodiment, a corrugated hose is connected between the inlet of the vacuum cleaner and the vacuum hood.

[0013] In a preferred embodiment, the inside of the coating box is provided with a film rolling roller and a coating roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This fully automatic laminating machine, through the setting of the guiding mechanism, can use the drive component to adjust the distance between the two guide plates so that the two sides of the paper contact the two guide plates respectively. Then, the cylinder is started to drive the pressure roller to descend, so that the pressure roller presses the two sides of the paper, thereby limiting the two sides of the paper and preventing the paper from deviating on the conveyor belt, thus improving the laminating quality.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-3 This utility model provides a fully automatic laminating machine, including a frame 1, a guiding mechanism 2, and a dust removal mechanism 3. A conveyor belt 11 is rotatably mounted on the frame 1. A feeding roller 12 and a receiving roller 13 are rotatably mounted at both ends of the frame 1, respectively. A laminating box 14 is fixedly mounted between the feeding roller 12 and the receiving roller 13 on the frame 1. The guiding mechanism 2 is located on the side of the laminating box 14 near the feeding roller 12. The dust removal mechanism 3 is located inside the laminating box 14 on the side near the feeding roller 12. The laminating box 14 is equipped with a film winding roller 15 and a laminating roller 16. During lamination, the paper end on the feeding roller 12 is pulled off and placed on the conveyor belt 11, so that the conveyor belt 11 conveys the paper. When the paper is conveyed into the laminating box 14, the guiding mechanism 2 guides the paper. After the paper enters the laminating box 14, the dust removal mechanism 3 removes dust from the surface of the paper. Then the paper is conveyed to the laminating roller 16 for lamination. After lamination, the paper is wound up by the receiving roller 13.

[0024] Specifically, the guiding mechanism 2 includes two guide plates 21 symmetrically arranged on the outer wall of the laminating box 14 and a driving component 22 for adjusting the distance between the two guide plates 21. A cylinder 23 is fixedly installed on the side of the two guide plates 21 that is close to each other. A connecting block 24 is fixedly connected to the piston end of the cylinder 23. A pressure roller 25 is rotatably installed on one side of the connecting block 24. Through the setting of the guiding mechanism 2, the distance between the two guide plates 21 can be adjusted by the driving component 22 so that the two sides of the paper contact the two guide plates 21 respectively. Then, the cylinder 23 is activated to drive the pressure roller 25 to descend, so that the pressure roller 25 presses the two sides of the paper, thereby limiting the two sides of the paper and preventing the paper from shifting on the conveyor belt 11, thus improving the laminating quality.

[0025] Specifically, the driving component 22 includes a bidirectional screw 221 rotatably mounted on the outer wall of the coating box 14 and a motor 222 for driving the bidirectional screw 221 to rotate. Two guide plates 21 are respectively sleeved on both ends of the bidirectional screw 221 and threadedly connected to the bidirectional screw 221. A guide rod 223 parallel to the bidirectional screw 221 is fixedly installed on the outer wall of the coating box 14. The guide plates 21 are slidably sleeved on the guide rod 223. By setting the driving component 22, when adjusting the distance between the two guide plates 21, the motor 222 can be started to drive the bidirectional screw 221 to rotate, so that the bidirectional screw 221 drives the two guide plates 21 to slide relative to or opposite to each other along the guide rod 223.

[0026] The guide plate 21 has a limiting groove 26 on its surface. One end of the connecting block 24 slides in the limiting groove 26. The limiting groove 26 can limit the connecting block 24 and improve the stability of the pressure roller 25.

[0027] Specifically, the dust removal mechanism 3 includes an electric push rod 31 fixedly installed on the top wall inside the laminating box 14, a housing 32 fixedly connected to the lower end of the electric push rod 31, and a cleaning roller 33 rotatably installed inside the housing 32. A scraper 34 is fixedly connected to the bottom of the housing 32 near the cleaning roller 33. A dust suction hood 35 with an opening facing the cleaning roller 33 is fixedly connected inside the housing 32. A vacuum cleaner 36 is fixedly installed on the top of the laminating box 14. A corrugated hose 37 is connected between the inlet of the vacuum cleaner 36 and the dust suction hood 35. With the setting of the dust removal mechanism 3, the electric push rod 31 can be activated to drive the housing 32 to descend, so that the housing 32 drives the cleaning roller 33 to contact the paper surface, so that the cleaning roller 33 can adsorb the dust on the paper surface. During the rotation of the cleaning roller 33, the scraper 34 will scrape off the dust adsorbed on the surface of the cleaning roller 33. At the same time, the vacuum cleaner 36 can be activated to suck the dust into the dust suction hood 35, thereby cleaning the paper surface and further improving the laminating quality.

[0028] The working principle and usage process of this utility model are as follows: First, during lamination, the paper end is pulled off the feed roller 12 and placed on the conveyor belt 11, allowing the conveyor belt 11 to transport the paper. As the paper is conveyed into the laminating box 14, the motor 222 is started to drive the bidirectional screw 221 to rotate, causing the bidirectional screw 221 to drive the two guide plates 21 to slide relative to each other along the guide rod 223. The distance between the two guide plates 21 is adjusted so that both sides of the paper contact the two guide plates 21 respectively. Then, the cylinder 23 is started to drive the pressure roller 25 to descend, causing the pressure roller 25 to press down on both sides of the paper, thereby laminating the paper. Limiting the two sides of the paper prevents it from shifting on the conveyor belt 11. After the paper enters the laminating box 14, the electric push rod 31 can be activated to drive the housing 32 to descend, so that the housing 32 drives the cleaning roller 33 to contact the paper surface, so that the cleaning roller 33 can adsorb the dust on the paper surface. During the rotation of the cleaning roller 33, the scraper 34 will scrape off the dust adsorbed on the surface of the cleaning roller 33. At the same time, the vacuum cleaner 36 can be activated to suck the dust into the dust suction hood 35 to remove dust from the paper surface. Then the paper is conveyed to the laminating roller 16 for lamination. After lamination, the paper is wound up by the take-up roller 13.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
