This energy-saving uniform coating device for release paper improves the uniformity of release agent coating and realizes the recycling of excess release agent.

[0004] While the aforementioned patent achieves a uniform coating device, improving the uniformity of release agent coating and enabling the recycling of excess release agent, the device also causes excessive dust to adhere to the release paper during use, resulting in coating defects and affecting the quality of release paper production. Utility Model Content

[0005] The purpose of this invention is to provide a uniform coating device for release paper, which solves the problem mentioned in the background art that excessive dust adheres to the release paper during use, causing coating defects during coating and thus affecting the quality of release paper production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a uniform coating device for release paper, comprising a workbench, a cleaning component fixedly connected to the top surface of the workbench, an installation box fixedly connected to the top surface of the workbench, and a drying component disposed inside the installation box. The cleaning component includes two sets of mounting rods fixedly connected to the top surface of the workbench, each set of mounting rods having a connecting rod connected to one side via a pivot shaft, each set of connecting rods having a fixing plate fixedly connected to one side, and an electrostatic dust removal rod fixedly connected to one side of each set of fixing plates. One end of the electrostatic dust removal rod is electrically connected to a high-voltage power supply via a power cord. The drying component includes a heating mesh disposed inside the installation box, one end of the heating mesh being electrically connected to a PLC controller via a power cord, and one end of the PLC controller being electrically connected to a fan via a power cord.

[0007] As a further embodiment of this utility model, the mounting box is internally fixedly connected with several sets of baffles, and the bottom surface of the fan is fixedly connected with a mounting plate. The mounting plate serves to fix the baffles.

[0008] As a further embodiment of this utility model, a support frame is fixedly connected to the top surface of the workbench, and a hydraulic rod is fixedly connected to the top surface of the support frame. One end of the hydraulic rod is fixedly connected to a connecting plate. The hydraulic rod serves to move the connecting plate.

[0009] As a further embodiment of this utility model, two sets of guide rods are slidably connected inside the connecting plate, and the liquid outlet of the connecting plate is rotatably connected to a lower pressure roller. The lower pressure roller is designed to make the release paper adhere to the surface of the coating roller.

[0010] As a further embodiment of this utility model, a coating roller is rotatably connected to one side of the support frame, and a rotating motor is fixedly connected to one end of the coating roller. A heat dissipation box is provided on the outside of the rotating motor. The coating roller serves to coat the release paper.

[0011] As a further embodiment of this utility model, a scraper is bolted to the surface of the workbench, and a release liquid placement groove is provided on the surface of the workbench. The scraper helps to make the release liquid on the coating roller more uniform.

[0012] As a further embodiment of this utility model, four sets of positioning rods are fixedly connected to the top surface of the workbench, and two sets of positioning rollers are rotatably connected to one side of the four sets of positioning rods. The positioning rollers serve to limit and guide the release paper.

[0013] This invention provides a uniform coating device for release paper, which has the following advantages: 1. This release paper uses a uniform coating device. Through the setting of the cleaning component, during use, the release paper is placed above the electrostatic dust removal bar, and the fixing plate limits the release paper. When the release paper is coated, the electrostatic dust removal bar rotates. The high-voltage power supply is used to power the electrostatic dust removal bar, which cleans the dust on the surface of the release paper. This effectively adsorbs and removes dust and impurities from the surface of the release paper, preventing dust from mixing into the coating during the coating process. This ensures the surface quality of the release paper after coating, reduces coating defects caused by impurities, improves the product qualification rate of the release paper, and also provides a higher quality substrate for subsequent processing, reducing the risk of defective products caused by surface impurities in subsequent processes.

[0014] 2. The release paper uses a uniform coating device. Through the setting of the drying component, after the release paper is coated, the PLC controller controls the heating grid to preheat and starts the fan. The air blown by the fan is heated by the heating grid and becomes hot air. The hot air dries the coated release paper, so that the coating can be cured and shaped in a short time. This avoids problems such as coating dripping, sticking or uneven surface caused by untimely drying, thereby ensuring the flatness and adhesion of the release paper coating, improving the physical properties and use effect of the product, and shortening the processing cycle of a single sheet of release paper, thus improving the overall operating efficiency of the production line.

The connecting plate 9 has two sets of guide rods 10 slidably connected inside, and the liquid outlet of the connecting plate 9 is rotatably connected to the lower pressure roller 11. The lower pressure roller 11 is designed to make the release paper adhere to the surface of the coating roller 12. A coating roller 12 is rotatably connected to one side of the support frame 7. A rotating motor is fixedly connected to one end of the coating roller 12. A heat dissipation box 13 is provided on the outside of the rotating motor.

[0019] In this invention, the working steps of the device are as follows: First step: When using the product, place the release paper above the electrostatic dust removal rod 204. The fixing plate 203 limits the release paper. When the release paper is coated, the electrostatic dust removal rod 204 rotates. The high-voltage power supply 205 supplies power to the electrostatic dust removal rod 204. The electrostatic dust removal rod 204 cleans the dust on the surface of the release paper, effectively adsorbing and removing dust and impurities.

The second step: After the release paper coating is completed, the PLC controller 402 controls the heating grid 401 to preheat and starts the fan 403. The air blown out by the fan 403 is heated by the heating grid 401 and becomes hot air. The hot air dries the coated release paper, so that the coating can be cured and shaped in a short time. This avoids problems such as coating dripping, sticking or uneven surface caused by untimely drying, thus ensuring the flatness and adhesion of the release paper coating, improving the physical properties and performance of the product, and shortening the processing cycle of a single sheet of release paper, thereby improving the overall operating efficiency of the production line.
