Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating knife technology, specifically a flexible adjustable roller coating knife. Background Technology
[0002] Roller coating blades are primarily used to evenly coat coatings onto substrates such as paper, film, synthetic leather, and reflective materials. They are the core component of roller coating machines. Through the rotation of the coating roller and its contact with the substrate, the coating is transferred and applied. During the coating process, the coating is fed onto the coating roller, and then evenly transferred onto the substrate through the roller's rotation and contact with the substrate. Adjusting screws allow for fine adjustments to the blade sleeve, thereby changing the straightness of the coating blade edge and the coating amount to meet different coating requirements.
[0003] Some existing coating knives require a baffle plate to block the coating during use. However, some existing baffle plates are adjusted by bolting. After long-term use, this method can easily cause the frame of the coating knife to become uneven, resulting in inaccurate positioning when adjusting the baffle plate.
[0004] Meanwhile, some existing baffles are prone to significant wear due to long-term friction with the coating roller, requiring regular replacement to prevent paint leakage. However, replacing existing baffles involves replacing the entire baffle, which is not only cumbersome but also wastes materials, reducing the applicability of the coating knife.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4As shown, a flexible adjustable roller coating knife includes a mounting frame 1. A scraping component 2 is installed inside the mounting frame 1. The scraping component 2 can scrape the adhesive evenly, allowing it to be spread uniformly onto the substrate to be coated. Two fixing rods 3 are fixedly connected to one side of the mounting frame 1. The surface of each fixing rod 3 is provided with scale lines 4. A blocking frame 5 is slidably connected to the surface of each fixing rod 3. The blocking frame 5 can block the adhesive, thereby adjusting the coating area. The fixing rods 3 also ensure greater stability during movement, and the scale lines 4 ensure more accurate positioning of the blocking frame 5 during movement, effectively improving the applicability of the coating knife. One side of the blocking frame 5 is fixedly connected to... A fixed frame 6 is provided, with its inner wall slidably connected to the surface of the fixed rod 3. The fixed frames 6 on one side and the fixed frame 6 on the other side have an interlocking structure design. This design facilitates adjustment of the blocking frame 5 and allows the fixed frame 6 to work in conjunction with the scale line 4 to adjust the position of the blocking frame 5. The two fixed frames 6 can move the blocking frame 5 according to a fixed rod 3, ensuring that fixing one blocking frame 5 does not affect the accuracy of the position of the other blocking frame 5. A pressing block 7 is provided inside the fixed frame 6, and a connecting rod 8 is fixedly connected to the top of the pressing block 7. The other end of the connecting rod 8 passes through the outside of the fixed frame 6 and is slidably connected to the inner wall of the through point. This design allows for adjustment of the blocking frame 5. The compression block 7 is moved by the action of the rod 8. The compression block 7 is made of rubber. The bottom of the compression block 7 is movably connected to the top of the fixed rod 3. Under this action, when the connecting rod 8 compresses the compression block 7, it can be squeezed against the fixed rod 3 by its own material, thereby fixing the blocking frame 5. The top of the fixed frame 6 is equipped with an adjustment mechanism 9, which works in conjunction with the connecting rod 8. Under this action, it is easier for the compression block 7 to contact the fixed rod 3, and it is also easier to move the blocking frame 5. A positioning groove 10 is opened on one side of the blocking frame 5. A positioning frame 11 is slidably connected to the inner cavity of the positioning groove 10. A blocking strip 12 is fixedly connected to one side of the positioning frame 11. One side of the blocking strip 12 is slidably connected to the surface of the blocking frame 5. Both the inner cavity of the positioning groove 10 and the cross-sectional shape of the positioning frame 11 are T-shaped. The positioning groove 10 and the positioning frame 11 work together to limit the positioning frame 11's position, preventing it from easily shifting or moving out of the positioning groove 10. This effectively improves the accuracy of the blocking strip 12's position. The blocking strip 12 has a flexible structure design, with one side working in conjunction with the scraping component 2. The consistent design of the blocking strip 12 blocks the adhesive, preventing it from overflowing and affecting the application effect. Furthermore, the interaction between the positioning groove 10 and the positioning frame 11 facilitates replacement of the blocking strip 12 when it needs to be replaced after long-term use.A blocking mechanism 13 is installed on one side of the top of the blocking frame 5. The blocking mechanism 13 can block the inner wall of the positioning groove 10, thereby preventing the positioning frame 11 from easily moving out of the positioning groove 10.
[0024] The adjustment mechanism 9 includes a positioning shell 91 fixed to the top of the fixing frame 6. A positioning block 92 is slidably connected to the inner cavity of the positioning shell 91. The surface of the positioning block 92 is fixedly connected to the surface of the connecting rod 8. Under this action, when it is necessary to fix the extrusion block 7, the positioning block 92 can be inserted into the interior of the positioning shell 91 by squeezing the extrusion block 7 and rotating the connecting rod 8, thereby limiting the extrusion block 7 and preventing it from moving easily and affecting the fixing effect of the blocking frame 5. A tension spring 93 is fixedly connected to the top of the inner cavity of the fixing frame 6. The other end of the tension spring 93 is fixedly connected to the top of the extrusion block 7. Under this action, the extrusion block 7 will not contact the fixing rod 3 when it is not under force, reducing the friction of the blocking frame 5 when it moves, thus making it more convenient to move the blocking frame 5 when it needs to be moved.
[0025] The blocking mechanism 13 includes a fixing groove 131 formed on one side of the top of the blocking frame 5. A compression spring 132 is fixedly connected to the inner cavity of the fixing groove 131. A locking plate 133 is fixedly connected to the other end of the compression spring 132. The surface of the locking plate 133 is movably connected to the surface of the positioning frame 11. Under this action, the locking plate 133 can block one side of the positioning frame 11 with the cooperation of the compression spring 132, so that the positioning frame 11 will not move easily. A toggle plate is fixedly connected to the top of the locking plate 133. 14. A blocking plate 15 is fixedly connected to one side of the actuating plate 14. Under the action of the actuating plate 14, an effective force point can be provided when the positioning plate 133 needs to be moved, so that the positioning plate 133 can be moved more easily. With the cooperation of the blocking plate 15, the opening of the fixing groove 131 can be blocked, so that when the positioning plate 133 limits the positioning frame 11, the glue will not enter the interior of the fixing groove 131 through the opening, thus avoiding the glue from affecting the normal use of the compression spring 132.
[0026] It is worth noting that the technical features such as the mounting bracket 1 and the scraping component 2 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.
[0027] Working principle: First, when the position of the blocking frame 5 needs to be adjusted, the operator rotates the connecting rod 8 to move the positioning block 92 out of the positioning shell 91. Under the action of the tension spring 93, the extrusion block 7 will no longer contact the fixing rod 3. Then, the position is adjusted according to the cooperation of the scale line 4 and the blocking frame 5. After adjusting to the appropriate position, the operator presses the connecting rod 8 to make the extrusion block 7 press the fixing rod 3 and then rotates to move the positioning block 92 into the positioning shell 91, thereby limiting the extrusion block 7. This not only makes it more convenient to adjust the position of the blocking frame 5, but also makes it more accurate. When the coating knife leaks after long-term use and the blocking strip 12 needs to be replaced, the operator moves the actuating plate 14 to make the locking plate 133 no longer block the positioning frame 11. Then, the positioning frame 11 is taken out from the positioning groove 10 through the blocking strip 12. Then, the new blocking strip 12 is taken out and installed. After installation, the locking plate 133 blocks the positioning frame 11 again under the action of the compression spring 132.
