Technical Field

[0001] This utility model relates to the technical field of roll coating and shunting coating machines, specifically to the adhesive scraping adjustment mechanism of roll coating and shunting coating machines. Background Technology

[0002] In modern industrial production, roll coating machines are widely used in the surface coating process of roll materials in fields such as building decoration materials, automobile manufacturing, and home appliance casings. The adhesive scraper adjustment mechanism, as its core component, directly determines the quality of adhesive coating and production efficiency.

[0003] In the prior art, the glue scraping adjustment mechanism usually consists of a support frame, a motor, a transmission screw, and a glue scraper. The position of the glue scraper is adjusted by the motor driving the transmission screw, thereby adapting to the thickness of the glue coating on different substrate surfaces.

[0004] However, during the production process, it is sometimes necessary to make some temporary, minor adjustments based on the real-time observation of the glue application. The motor-driven transmission screw is usually adjusted according to a preset program or fixed parameters, which makes it difficult to respond quickly to different production needs, resulting in poor adjustment flexibility.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1

[0024] Please see Figures 1 to 2 The present invention provides a technical solution: a scraper adjustment mechanism for a roll coating machine, comprising a machine body 1, a coating roller 2 disposed on the surface of the machine body 1, a support frame 3 fixedly connected to both sides of the surface of the machine body 1, a movable plate 6 slidably connected to the surface of the support frame 3, a fixed block 14 fixedly connected to the surface of the movable plate 6, a stop block 15 inserted into the two ends of the fixed block 14, a connecting plate 7 disposed between the two movable plates 6, the stop block 15 pressing against the surface of the connecting plate 7, a manual screw 10 screwed to the surface of the connecting plate 7, and a scraper 8 rotatably connected to one end of the manual screw 10;

[0025] The position of the scraper plate 8 is coarsely adjusted by the transmission screw 5 driven by the motor 4, and finely adjusted by the manual screw 10. This allows for precise adjustment of the distance between the scraper plate 8 and the substrate, quickly adapting to different production needs and improving the flexibility of the equipment. The surface of the moving plate 6 is equipped with a fixing block 14. Through the cooperation of the stop block 15, spring 17 and center rod 16, the connecting plate 7 and the scraper plate 8 can be quickly disassembled and installed. The operation is simple and convenient, improving maintenance efficiency.

[0026] Example 2

[0027] Please see Figures 1 to 4Based on Embodiment 1, in order to disassemble the scraper 8, multiple rollers are provided on the surface of the machine body 1, and a collection box 9 is attached to the surface of the machine body 1. The collection box 9 is located between two support frames 3. When the scraper 8 scrapes and adjusts the adhesive layer on the coating roller 2, some adhesive will be scraped off. The collection box 9 can collect these scattered adhesives to prevent adhesive from dripping onto other parts of the machine body 1 and prevent adhesive from contaminating the working environment.

[0028] An auxiliary rod 19 is fixedly connected to the inner cavity of a support frame 3. The auxiliary rod 19 passes through a through hole on the surface of a movable plate 6. The auxiliary rod 19 is set so that the movable plate 6 can only move along the axial direction of the auxiliary rod 19, ensuring the linearity and stability of the movement of the movable plate 6. A motor 4 is fixedly connected to the surface of another support frame 3. A transmission screw 5 is rotatably connected to the inner cavity of the support frame 3. One end of the transmission screw 5 extends through to the top surface of the support frame 3 and connects to the output end of the motor 4. The transmission screw 5 is engaged with a threaded hole on the surface of the other movable plate 6. The transmission screw 5 is driven to rotate by the motor 4, thereby realizing the movement of the movable plate 6, and thus the position of the scraper plate 8 can be coarsely adjusted.

[0029] The fixing block 14 has a square plate structure. Expansion grooves 18 are provided on both sides of the fixing block 14. A central rod 16 is fixedly connected to one end of the expansion groove 18. The central rod 16 provides support for the spring 17. The central rod 16 has a circular plate structure with a "T" shaped cross section. The spring 17 is sleeved on the surface of the central rod 16.

[0030] Example 3

[0031] Please see Figures 1 to 5 Based on Embodiment 2, in order to finely adjust the scraper 8, the stop block 15 has a square block structure. The two stop blocks 15 have inclined surfaces on their opposite ends, which serve as guides when installing the connecting plate 7. When the connecting plate 7 approaches the fixing block 14, the inclined surfaces guide the stop blocks 15 to automatically retract inward, making it easier for the connecting plate 7 to be smoothly inserted into the fixing groove 13 and reducing the installation difficulty.

[0032] The surface of the stop block 15 is provided with a movable groove 20, one end of the center rod 16 is inserted into the movable groove 20, the two ends of the spring 17 are respectively fixedly connected to the surface of the telescopic groove 18 and the stop block 15, the two ends of the connecting plate 7 are provided with fixed grooves 13, and the fixed block 14 passes through the fixed groove 13.

[0033] The surface of the connecting plate 7 is provided with two round holes 12 and one threaded hole 2. A guide rod 11 passes through the surface of the round holes 12. The round holes 12 and the guide rod 11 are used to guide the movement of the scraper plate 8. The threaded hole 2 is connected to the threaded part 2 on the surface of the manual screw 10. Using the thread transmission principle, the scraper plate 8 can be finely adjusted in the vertical direction. One end of the guide rod 11 is fixedly connected to the surface of the scraper plate 8. One end of the scraper plate 8 is provided with an arc surface. The arc surface structure facilitates the flow of glue and avoids glue accumulation at the front end of the scraper plate 8, ensuring the continuity and smoothness of the scraping process.

[0034] In actual use, when it is necessary to adjust the position of the scraper 8, first start the motor 4, which drives the moving plate 6 to move through the transmission screw 5. The moving plate 6 drives the connecting plate 7 to move, thereby making a preliminary position adjustment of the scraper 8. Then, turn the manual screw 10 to precisely adjust the distance between the scraper 8 and the substrate. The scraper 8 scrapes off the excess glue on the surface of the substrate. The scraped glue overflows to both sides along the arc of the scraper 8. The overflowing glue falls into the collection box 9 for collection.

[0035] When the scraper blade 8 needs to be replaced, press the two blocks 15 simultaneously. The blocks 15 compress the spring 17, causing the spring 17 to change from its initial state to a compressed state. The blocks 15 then release their pressure on the connecting plate 7 and retract into the telescopic groove 18. The connecting plate 7 loses its limit. Then, separate the fixing block 14 from the fixing groove 13 to disassemble and maintain the scraper blade 8.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
