Description

Technical Field

[0001] This utility model relates to the field of vapor phase rust inhibitor paper processing technology, and specifically to a vapor phase rust inhibitor paper coating equipment. Background Technology

[0002] Vapor phase corrosion inhibitor (VCI) paper, as an important rust-preventive packaging material, is widely used for rust protection of metal products. VCI paper typically uses special neutral paper as a base material, coated with different formulations of special substances—vapor phase corrosion inhibitors (VCI), and undergoes a series of post-processing steps. To further improve the protective performance of VCI paper, extend its service life, and meet the rust prevention requirements under different environmental conditions, a protective film is often applied to its surface.

[0003] The authorization announcement number CN217123972U discloses a vapor phase rust inhibitor paper coating equipment. This equipment cleans the upper surface of the vapor phase rust inhibitor paper with a cleaning brush plate to separate the attached dust from the vapor phase rust inhibitor paper. Then, a dust suction plate and a vacuum cleaner are used to suck up the separated dust and other impurities into the vacuum cleaner, thereby achieving a cleaning effect. The coating operation is then carried out. This can improve the adhesion effect of the protective film and ensure the quality of the rust inhibitor paper.

[0004] While the aforementioned vapor phase rust-preventive paper coating equipment has the advantage of surface cleaning of the rust-preventive paper before coating, it still has some shortcomings that warrant further optimization and improvement. For example, the equipment lacks a limiting structure to restrict the position of the rust-preventive paper. When the cleaning brush plate and dust suction plate clean the rust-preventive paper, the lack of a limiting structure makes it prone to displacement under the action of friction and adsorption forces. This not only affects the cleaning effect but may also adversely affect subsequent coating operations.

[0005] Therefore, it is necessary to invent a vapor phase rust-preventing paper coating device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a vapor phase rust-preventive paper coating device to solve the problems in the above-mentioned technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vapor phase rust-preventive paper coating device, comprising an operating table, a fixed support fixedly connected to the top of the operating table, a first electric push rod and a second electric push rod installed on the inner top surface of the fixed support, a cleaning component arranged directly below the first electric push rod, the cleaning component comprising a first loading plate, the bottom working end of the first electric push rod fixedly connected to the middle of the top of the first loading plate, a loading frame and a negative pressure suction nozzle fixedly connected to the middle of the bottom of the first loading plate, a cleaning roller rotatably connected inside the loading frame, cleaning bristles fixedly connected to the surface of the cleaning roller, a first motor installed on one side of the loading frame, one end of the cleaning roller being drivenly connected to the output shaft of the first motor, a vacuum cleaner installed on the top of the fixed support, and the negative pressure suction nozzle being connected to the suction port of the vacuum cleaner through a telescopic conduit;

A No. 1 limiting pressure roller is rotatably connected inside each of the two No. 1 brackets.

[0009] A controller is installed on the front of the control panel, and the No. 1 electric push rod, No. 2 electric push rod, No. 1 motor and vacuum cleaner are all electrically connected to the controller.

[0010] By setting up cleaning components, including a No. 1 electric push rod, cleaning roller, and negative pressure suction nozzle, the surface of vapor phase rust-preventive paper is automatically cleaned, effectively removing dust and impurities, improving the adhesion of the protective film and the coating quality. At the same time, the design of the limiting pressure roller ensures the stability of the rust-preventive paper during the cleaning process and prevents the occurrence of deviation.

[0011] Preferably, the suction inlet of the negative pressure nozzle is opened towards the cleaning roller, and the controller can control the first motor to drive the cleaning roller to rotate towards the suction inlet of the negative pressure nozzle.

[0012] The suction inlet of the negative pressure nozzle is opened towards the cleaning roller, and the controller can control the cleaning roller to rotate towards the suction inlet of the negative pressure nozzle. This design allows the dust and impurities generated during the cleaning process to be sucked into the vacuum cleaner more directly, improving cleaning efficiency and effectiveness.

[0014] A feeding trough is opened at the top of the fixed bracket, and a protective film feeding roller is set to facilitate the traction of the protective film to cover the surface of the vapor phase anti-rust paper.

[0015] Preferably, a second motor is installed on the back of the fixed bracket, one end of the protective film feeding roller is connected to the output shaft of the second motor, and the second motor is electrically connected to the controller.

The bottom working end of the second electric push rod is fixedly connected to the middle of the top of the second loading plate. Multiple evenly distributed second brackets are provided at the bottom of the second loading plate. Multiple second telescopic rods arranged in a linear array are fixedly connected between the top of the multiple second brackets and the bottom of the second loading plate.

[0018] The coating assembly is lowered to the appropriate position by driving the No. 2 electric push rod, and the No. 2 limit pressure roller applies appropriate pressure to the anti-rust paper and protective film to ensure the tightness of the coating.

[0019] Preferably, each of the second telescopic rods is fitted with a second spring, the top end of the second spring abuts against the bottom of the second loading plate, the bottom end of the second spring abuts against the top of the second bracket, and each of the second brackets is rotatably connected to a second limiting pressure roller.

[0020] The design of the No. 2 telescopic rod and the No. 2 spring provides a certain buffering effect during the descent of the coating assembly, preventing damage to the anti-rust paper and protective film due to excessive pressure. At the same time, this design also enhances the adaptability of the coating assembly to anti-rust paper and protective film of different thicknesses.

[0021] Preferably, each end of the operating table is rotatably connected to a guide roller, and the two guide rollers are arranged along the conveying direction of the vapor phase rust-preventing paper.

[0022] Guide rollers are installed at both ends of the operating table to facilitate guiding the vapor phase rust-preventive paper to be coated through the top of the operating table.

[0023] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0024] 1. By setting a first limiting pressure roller on the cleaning component, the first limiting pressure roller applies appropriate pressure to the vapor phase rust-preventing paper through the action of a first telescopic rod and a first spring, limiting its position and preventing it from shifting during the cleaning process. This helps to enhance the accuracy and consistency of the coating operation and improve the coating quality.

[0025] 2. The cleaning roller and negative pressure nozzle in the cleaning component thoroughly clean the surface of the vapor phase rust-preventive paper, effectively removing attached dust and impurities. This improves the adhesion of the protective film and avoids problems such as bulging, wrinkling, or separation of the protective film from the rust-preventive paper caused by surface contaminants, thereby improving the overall quality of the coating.
