A VOC tape adhesive uniform coating device

Abstract

This utility model discloses a uniform coating device for VOC tape adhesive in the field of adhesive coating technology. It includes a frame and a mounting plate. The mounting plate is fixedly connected to the inner side of the frame. A first rotating shaft is rotatably connected to the inner side of the frame, and a stirring rod is fixedly connected to the outer side of the first rotating shaft. A heating box is fixedly connected to the inner side of the frame. This uniform coating device for VOC tape adhesive has a reasonable structural design. Starting a second motor drives the second rotating shaft and the coating roller to rotate, causing the coating roller to rotate and absorb the adhesive. When the coating roller rotates, it contacts a metering scraper, which scrapes away excess adhesive from the surface of the coating roller, ensuring a uniform adhesive thickness. After coating, the coating roller rotates and contacts a recovery scraper, which scrapes away any remaining adhesive from the surface of the coating roller. This prevents the adhesive from cooling and solidifying, which could cause unevenness on the surface of the coating roller and thus improves the processing quality.

Then comes the coating process, which can be done by transfer coating or direct coating, with precise control over the coating thickness.

[0003] Chinese patent publication number "CN207746039U" discloses "An adhesive coating device with controllable coating thickness". This application includes a coating roller, two adjusting blocks respectively installed at both ends of the coating roller, and two fastening nuts. Each of the adjusting blocks is a rectangular structure, and the part of the adjusting block near the object to be coated is provided with a hollow roller groove.

[0004] This patent uses a coating roller to apply adhesive, but after prolonged use, the adhesive on the innermost layer of the coating roller surface is prone to cooling and freezing, causing unevenness on the coating roller surface, which can lead to uneven application and reduce processing quality.

[0005] Therefore, a device for uniformly coating VOC tape adhesive is proposed here. Utility Model Content

[0006] The purpose of this invention is to provide a device for uniformly coating VOC tape adhesives, in order to solve the problem mentioned in the background art that the adhesive on the innermost layer of the coating roller surface is prone to cooling and freezing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a VOC tape adhesive uniform coating device, comprising a frame and a mounting plate, the mounting plate being fixedly connected to the inner side of the frame, a first rotating shaft being rotatably connected to the inner side of the frame, a stirring rod being fixedly connected to the outer side of the first rotating shaft, a heating box being fixedly connected to the inner side of the frame, an electric heating tube being fixedly connected to the inner side of the heating box, a first motor being fixedly connected to the outer side of the frame, the first rotating shaft penetrating the inner cavity of the frame and extending to the outer side of the frame, a driving wheel being fixedly connected to the outer side of the first rotating shaft, the power output shaft of the first motor being fixedly connected to the driving wheel, a driven wheel being fixedly connected to the outer side of the first rotating shaft, a belt being fixedly connected between the outer sides of the driving wheel and the driven wheel, a second motor being fixedly connected to the outer side of the frame, a second rotating shaft being fixedly connected to the end of the power output shaft of the second motor, and a coating roller being fixedly connected to the outer side of the second rotating shaft.

[0009] As a further description of the above technical solution: a mounting frame is fixedly connected to the top of the frame, a first cylinder is fixedly connected to the top of the mounting frame, a push plate is fixedly connected to the end of the power output shaft of the first cylinder, a pressure roller is rotatably connected to the inner side of the push plate, and a telescopic rod is fixedly connected between the push plate and the mounting frame.

[0010] As a further description of the above technical solution: support columns are fixedly connected to the four bottom corners of the frame, and anti-slip pads are fixedly connected to the bottom of the support columns.

[0014] 2. This VOC tape adhesive uniform coating device starts by starting the second motor to drive the second rotating shaft and coating roller to rotate, causing the coating roller to rotate and absorb the adhesive. When the coating roller rotates, it comes into contact with the metering scraper, which scrapes away excess adhesive from the surface of the coating roller, making the adhesive thickness on the coating roller surface uniform. After coating is completed, the coating roller rotates and comes into contact with the recovery scraper, which scrapes away the remaining adhesive from the surface of the coating roller. This prevents the adhesive from cooling and solidifying, which would cause unevenness on the surface of the coating roller and thus uneven coating, thereby improving the processing quality.

The controller 170 is used to facilitate the centralized control of the heating element 113, the first motor 120, the second motor 130, the first cylinder 141 and the second cylinder 210 by the staff.

[0025] In summary, starting the second motor 130 drives the second rotating shaft 131 and the coating roller 132 to rotate, causing the coating roller 132 to rotate and absorb the adhesive. When the coating roller 132 rotates, it comes into contact with the metering scraper 211, which scrapes away excess adhesive from the surface of the coating roller 132, ensuring a uniform adhesive thickness on the surface of the coating roller 132. After coating is completed, the coating roller 132 rotates and comes into contact with the recovery scraper 220, which scrapes away any remaining adhesive from the surface of the coating roller 132. This prevents the adhesive from cooling and solidifying, which could cause unevenness on the surface of the coating roller 132 and thus result in uneven coating, thereby improving the processing quality.

[0026] In practical use, those skilled in the art inject the adhesive through the feed pipe 160, start the heating element 113 to heat the adhesive, start the first motor 120 to drive the drive wheel 121 to rotate, and then drive the driven wheel 122 to rotate through the belt 123, thereby driving the first rotating shafts 110 on both sides and the stirring rod 111 to rotate, so that the stirring rod 111 stirs the adhesive. Start the second motor 130 to drive the second rotating shaft 131 and the coating roller 132 to rotate, so that the coating roller 132 rotates to absorb the adhesive. When the coating roller 132 rotates, it contacts the metering scraper 211, so that the metering scraper 211 scrapes away the excess adhesive on the surface of the coating roller 132, so that the adhesive thickness on the surface of the coating roller 132 is uniform. After the coating is completed, the coating roller 132 rotates and contacts the recovery scraper 220, so that the recovery scraper 220 scrapes away the remaining adhesive on the surface of the coating roller 132.

[0027] It should be noted that the heating element 113, the first motor 120, the second motor 130, the first cylinder 141, the controller 170, and the second cylinder 210 mentioned in the text are all existing technologies. The model number of the heating element 113 is EF-903. Its principle is as follows: by connecting a power source to the terminals, electricity is conducted through the terminals to the resistance wire. The resistance wire generates heat, which is then conducted to the surface of the heating element 113 via the highly thermally conductive magnesium oxide powder, thus generating heat on the surface of the heating element 113. The model numbers of the first motor 120 and the second motor 130 are Y80M1-2. Their principle is as follows: based on the law of electromagnetic induction, they are electromagnetic devices that realize the conversion of electrical energy and electromechanical energy. They can convert electrical energy into mechanical energy, and vice versa. The conversion between different forms of electrical energy is described; the first cylinder 141 and the second cylinder 210 are model SDA40; the principle is: power is generated inside the cylinder by compressed air, which pushes the piston rod to perform reciprocating linear motion; the controller 170 is model ADAM-5510M; the principle is: including PLC and memory, specifically, when the PLC is running, the PLC performs periodic cyclic scanning according to the instruction step number or address number, based on the program compiled by the user according to the control requirements and stored in the user program memory.
