Description

Technical Field

[0001] This utility model relates to the field of paper coating technology, specifically a paper coating device. Background Technology

[0002] Film paper is a composite material made by coating plastic particles onto the surface of paper using a casting machine. Its main characteristics are oil and water resistance, and heat sealing capability. The paper is fed into and unwound, moved by traction rollers, and coated and cooled to form a film layer, achieving water and oil resistance. In related technologies, the paper coating device includes a frame, a roller mounted on the frame, and a coating frame mounted on the frame. The coating frame is attached to the roller and contains silicone oil for coating the film layer. After the silicone oil is applied, an adhesive is applied to the film layer. Adhesive paper adheres to the side of the adhesive layer away from the film layer. Applying silicone oil to the film layer reduces the bonding strength between the film layer and the adhesive, facilitating subsequent separation of the film layer from the adhesive paper.

[0003] For example, CN219723513U discloses a paper coating device, which relates to the field of automation equipment technology. It includes a frame, a conveyor motor and a coating roller connected to the output shaft of the conveyor motor on the frame, a coating motor on the frame, a drive tooth connected to the output shaft of the coating motor, the drive tooth meshing with a driven tooth, and a storage frame connected to the driven tooth. The storage frame has a storage slot for storing silicone oil. When applying silicone oil, the storage frame can be rotated and fastened to the coating roller. The coated paper passes between the coating roller and the storage frame, and the silicone oil stored in the storage slot can be applied to the coated paper. An antistatic component for eliminating static electricity on the coated paper is provided on the side of the frame away from the storage frame.

[0004] The above application can achieve the effect of adjustable silicone oil coating thickness, but it still uses a coating roller. The roller rolls on the paper to press the silicone oil onto the paper. However, the silicone oil is not uniform when it comes into contact with the paper, which means that the coating roller needs to roll multiple times to coat the silicone oil onto the surface of the paper, affecting production efficiency. Therefore, the market urgently needs to develop a paper coating device to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a paper coating device to solve the problem mentioned in the background art that ordinary test tubes are prone to contamination of samples by external substances.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paper coating device, comprising a conveying device, wherein a coating mechanism and a leveling mechanism are respectively provided on the conveying device, the coating mechanism comprising a transverse moving device, a lifting device and a leveling hopper, a roller frame is fixedly installed below the leveling hopper, a coating roller is rotatably connected below the roller frame, a plug is provided at the outlet of the leveling hopper, a screw and a stabilizing shaft are fixedly installed above the plug, a hopper cover is fixedly installed above the leveling hopper, a screw seat is rotatably connected to the hopper cover, the screw seat is threadedly connected to the screw, a second bevel gear is fixedly installed on the outer side of the screw seat, a fourth driving device is fixedly installed on the hopper cover, a first bevel gear is connected to the driving end of the fourth driving device, the first bevel gear and the second bevel gear are meshed together, and a number of stabilizing shafts are slidably connected to the hopper cover.

[0007] With the above technical solution, a uniform hopper is set on the coating roller, and the discharge end of the uniform hopper is located directly above the coating roller. The discharge port of the uniform hopper is the same length as the coating roller. Thus, when the stopper moves up, the silicone oil in the uniform hopper will be poured onto the top of the coating roller at the same time, so that the surface of the coating roller is coated with silicone oil in all directions. At this time, when the coating roller rolls on the paper, it can spread the silicone oil evenly on the paper, improve the uniformity of silicone oil coating, and the coating roller does not need to coat the paper multiple times, thus improving the work efficiency of paper coating.

[0008] In a preferred embodiment, the present invention can be further configured such that: the lifting device is slidably connected to the transverse moving device, the equalizing hopper is slidably connected to the lifting device, and a connector is fixedly installed on one side of the equalizing hopper.

[0009] In a preferred embodiment, the present invention can be further configured as follows: a conveying roller is rotatably connected inside the conveying device, a conveyor belt is provided on the outer side of the conveying roller, a first driving device is fixedly installed inside the conveying device, and a transmission wheel set is driven between the first driving device and the conveying roller.

[0010] Through the above technical solution, the first driving device drives the conveyor roller to rotate through the transmission wheel set. Multiple conveyor rollers are provided. The rotation of the conveyor roller drives the conveyor belt to rotate, thereby conveying the paper.

[0014] Through the above technical solution, the third driving device drives the driving gear to rotate, and the driving gear drives the second lead screw to rotate through the driven gear. The rotation of the second lead screw drives the second lead screw seat to move vertically, thereby adjusting the height of the equalizing hopper so that the coating roller can be used for paper of different thicknesses.

[0016] The above technical solution utilizes an electric telescopic rod to adjust the height of the even spreader. The even spreader has a triangular structure with its pointed end facing the opposite direction to the paper's conveying direction. As a result, during the paper conveying process, the silicone oil on the surface will be guided to both sides, scraping off any excessively high silicone oil layer, thereby further improving the uniformity of the paper surface and enhancing the paper's coating quality.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model features a material distribution hopper on the coating roller, with the discharge end of the hopper positioned directly above the coating roller. The discharge port of the hopper is the same length as the coating roller. Thus, when the stopper moves up, the silicone oil in the material distribution hopper is simultaneously poured onto the top of the coating roller, ensuring that the coating roller surface is coated with silicone oil in all directions. When the coating roller rolls on the paper, it can evenly spread the silicone oil on the paper, improving the uniformity of silicone oil coating. The coating roller does not need to coat the paper multiple times, thus improving the efficiency of paper coating.

[0019] 2. This utility model utilizes an electric telescopic rod to adjust the height of the even spreader. The even spreader has a triangular structure, with its pointed end set in the opposite direction to the paper conveying direction. Thus, during the paper conveying process, the silicone oil on the surface will be guided to both sides, scraping off the excessively high silicone oil layer, thereby further improving the uniformity of the paper surface and improving the coating quality of the paper.
