Description
Technical Field
[0001] The utility model relates to the technical field of coating devices, in particular to a wire rod type coating device. Background Art
[0002] In industrial production, coating technology is widely used in many fields such as electronics, packaging, medicine and printing. Its purpose is to form a uniform film on the surface of the substrate to meet the functional or decorative requirements of the product;
[0003] Wire rod coating is a commonly used coating process. The slurry is evenly spread on the surface of the substrate through the uniform gaps on the wire rod, and the desired film layer is formed during the subsequent drying process.
[0004] Traditional screen coating involves carving cells on the surface of a screen roller, with paint in a sealed feed cavity. The cells are then filled with paint as the roller rotates, and excess paint is scraped off the surface of the roller when it leaves the sealed feed cavity, leaving only paint in the cells. When the roller rotates to the point where it meets the rubber outer cylinder, the pressure of the rubber outer cylinder on the roller causes the paint in the cells to be brought out and adhere to the substrate surface. However, due to the manufacturing process of the cells on the surface of the screen roller, the paint transferred to the substrate at this time appears as an uneven coating surface, with uneven coating thickness, which can easily affect the final quality and finished product effect. Utility Model Content
[0005] The main purpose of the present utility model is to provide a wire rod coating device, which can effectively solve some of the existing technologies proposed above. In traditional wire mesh coating, mesh holes are carved on the surface of the wire mesh roller, and paint is filled in the sealed feeding cavity. When the wire mesh roller rotates, the mesh holes are filled with paint and the excess paint on the surface of the wire mesh roller is scraped off when leaving the sealed feeding cavity. Only paint is left in the mesh holes. When the wire mesh roller rotates to the junction with the rubber outer cylinder, the pressure of the rubber outer cylinder on the wire mesh roller causes the paint inside the mesh holes to be brought out and attached to the surface of the substrate. However, due to the manufacturing process of the mesh holes on the surface of the wire mesh roller, the paint transferred to the substrate at this time is an uneven coating surface from a microscopic point of view, and the coating is uneven in thickness, which can easily affect the final quality of the product and the effect of the finished product.

DETAILED DESCRIPTION
[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0028] Example 1, as Figure 1 As shown, a wire rod type coating device includes a supporting mechanism 1, a fixing mechanism 2 is fixedly connected to the left side of the top of the supporting mechanism 1, the front and rear ends of the outer surface of the fixing mechanism 2 are fixedly connected to the driving device 7, the side of the top of the supporting mechanism 1 is fixedly connected to the supporting outer frame 3, a mounting mechanism 4 is arranged above the fixing mechanism 2, a wire rod mechanism 6 is installed in the middle of the opposite side of the inner surface of the mounting mechanism 4, an adjustment mechanism 10 is fixedly connected to the top of the mounting mechanism 4 symmetrically front and back, a collecting basket 9 is placed in the middle of the left side of the top of the supporting mechanism 1, and a feeding mechanism 5 is installed at the right end of the fixing mechanism 2.
[0029] During the implementation of this embodiment, the wire rod mechanism 6 is installed between the mesh roller 202 and the left-end guide roller 403. The angle between the material-leveling wire rod 605 and the substrate 8, that is, the contact area, is controlled by the electric telescopic plate 602. The above devices are all installed on the mounting mechanism 4. The mounting mechanism 4 causes the rubber pressure roller 402 and the mesh roller 202 to generate pressure. The substrate 8 passes between the mesh roller 202 and the rubber pressure roller 402, and the coating is transferred from the mesh roller 202 to the surface of the substrate 8.
[0030] At this time, the coating on the surface of the substrate 8 may be locally accumulated or uneven in thickness. In order to obtain a smooth coating surface for the substrate 8, a certain relative friction is formed at the corners through the wire rod mechanism 6 to make the surface of the substrate 8 uniform and smooth. The material leveling wire rod 605 is connected to the drive motor 612 by the universal joint 609 and the rotating assembly 610. The speed of the material leveling wire rod 605 is automatically controlled by the PLC control system. The quantitative coating surface thickness is determined by the mesh parameters engraved on the outer side of the material leveling wire rod 605 and the wire rod speed.
[0031] The two driving devices 7 at the front end drive the two guide rollers 403 to rotate respectively, thereby conveying the substrate 8. The scraper 1 502 can scrape off the excess paint on the mesh roller 202, and the scraper 2 608 can scrape off the excess paint on the outside of the leveling rod 605, thereby helping to ensure the uniformity of the coating.
[0032] This allows users to avoid increasing the coating thickness in order to obtain a stable coating structure on the substrate surface, reduces the amount of coating transfer, and greatly reduces production costs.
