Description

Technical Field

[0001] The invention relates to the technical field of coating machine scraper blades, in particular to a coating machine scraper blade adjustment mechanism. Background Art

[0002] A coater is a device used to evenly coat the coating material on the surface of a substrate. It is widely used in the surface treatment of paper, film, metal, glass, textiles and other materials, and involves industries such as packaging, printing, electronics, optoelectronics, automobiles and medical treatment. The coating machine is mainly studied and improved around the uniformity of the coating, the adhesion of the coating, the speed of coating, and the drying and curing after coating.

[0003] For example, the "A coating machine glue scraper adjustment device" with publication number: CN119016299A includes an adjustment roller, a glue scraper, an adjustment mechanism, and an end adjustment mechanism. A mounting groove is provided on the roller surface of the adjustment roller, and a placement block is provided in the mounting groove. Blade clamps are provided at the top of the placement block and the top of the mounting groove, respectively. The glue scraper is provided between the two blade clamps. The adjustment mechanism includes a plurality of reference plates and a fixed plate. The reference plate is parallel to the blade clamp, and the reference plate is fixedly connected to the placement block through the fixed plate. A plurality of adjustment holes are provided on the reference plate, and an adjustment screw is provided in the adjustment hole. The end of the adjustment screw contacts the blade clamp. A coating machine glue scraper adjustment device using the above structure can accurately adjust the gap between the glue scraper and the substrate to be coated, so that the glue is evenly coated, thereby improving the coating quality.

[0004] In the prior art, although this type of coater scraper plays a role in accurately adjusting the gap between the gluing scraper and the substrate to be coated, so that the glue is evenly coated, thereby improving the coating quality effect, it is lacking in the disassembly and replacement of the scraper. Since this type of coater scraper does not have a structure for quickly disassembling the adjustment roller, it will cause the operator to spend a lot of time disassembling and installing the adjustment roller, resulting in a significant increase in the coater downtime. For example, in some large-scale printing and coating companies, a one-minute shutdown may cause several meters or even tens of meters of substrate to be wasted. There is no quick disassembly and assembly structure, and the process of replacing the adjustment roller is cumbersome and complicated. It is necessary to use a variety of tools and remove multiple components in turn to take out the adjustment roller. When installing a new adjustment roller, it is necessary to repeatedly debug the installation position and angle, which consumes a lot of manpower and time, greatly reducing production efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When in use, by pulling the handle, the handle will drive the fixed seat A to slide on the surface of the movable seat A, and will also slide on the surface of the limit rod A. At this time, the fixed seat A will drive the fixed block A to move horizontally. After the plug block slides out from the inside of the fixed block A, the scraper mechanism can be pulled out from the fixed block B on the fixed seat B. At this time, the new scraper mechanism is inserted into the fixed block B through the plug block, and the plug block at the other end of the scraper mechanism is aligned with the fixed block A and then the handle is released. At this time, the fixed seat A will slide on the surface of the limit rod A and the movable seat A under the elastic force of the spring. When the plug block is inserted into the inside of the fixed block A, the scraper mechanism can be disassembled and replaced. When the angle of the scraper mechanism needs to be adjusted, just pull the paddle When the paddle is turned, the paddle will drive the slide bar A to slide inside the moving seat B through the connecting rod, and the connecting rod will drive the fixed rod to slide out of the fixed hole. At this time, the turntable is rotated, and the turntable will drive the scraper mechanism and the fixed block A to rotate in the fixed seat A through the fixed block B and the plug block, thereby completing the adjustment of the scraper mechanism. The quick disassembly and assembly structure can replace the scraper roller in a short time, and the equipment can quickly resume production, thereby improving the effective operation time of the equipment and increasing product output. This structural design simplifies the disassembly and assembly process of the scraper roller. The operator does not need to use complex tools or perform cumbersome operating steps, and can quickly and accurately complete the disassembly and installation of the scraper roller, further improving production efficiency.

[0019] 2. When in use, the fixed seat A and the fixed seat B can be installed on the coating machine through the inserts on the fixed seat A and the fixed seat B. When adjusting the distance between the fixed seat A and the fixed seat B, the fixed seat A and the fixed seat B will drive the fixed frame on the movable seat A and the movable seat B to move. At this time, the fixed frame will drive the rotating shaft A to slide on the surface of the turning handle, so that the limit block slides in the limit groove, thereby completing the adjustment of the distance between the fixed seat A and the fixed seat B. When it is necessary to adjust the height of the scraper mechanism, just turn the turning handle. When the turning handle is turned, it will drive the rotating shaft A to rotate through the limit block and the limit groove. The rotating shaft A will drive the bevel gear A to rotate, and the bevel gear A will drive the rotating shaft B to rotate through the bevel gear B. When the rotating shaft B rotates, it will drive the fixed frame to drive the moving seat A and the moving seat B to slide inside the fixed seat A and the fixed seat B through the screw A. At this time, the moving seat A and the moving seat B will move up and down along the limit rod B, thereby completing the up and down adjustment of the scraper mechanism. The adjustable spacing design of the fixed seat A and the fixed seat B makes the scraper adjustment mechanism suitable for different models of coating machines, thereby improving the adaptability of the scraper adjustment mechanism, making it convenient to scrape materials of different widths;

[0020] 3. When in use, by rotating the fixing pin, after the fixing pin is rotated out of the clamping plate B, the fixing pin can be pulled out from the scraper blade and clamping plate A, and then the bidirectional screw rod B is rotated. When the bidirectional screw rod B rotates, it will drive clamping plates A and clamping plates B to move horizontally inside the limit plate A. At this time, clamping plates A and clamping plates B will also move horizontally inside the limit rod B and limit plate B. When clamping plates A and clamping plates B are away from the scraper blade, the scraper blade can be pulled out from clamping plates A and clamping plates B, and then a new scraper blade can be inserted between clamping plates A and clamping plates B. By rotating the bidirectional screw rod in the opposite direction, the scraper blade can be pulled out from clamping plates A and clamping plates B, and then a new scraper blade can be inserted between clamping plates A and clamping plates B. Rod B, so that clamp A and clamp B clamp and fix the scraper blade. After the soft pad fits the scraper blade tightly, insert the fixing pin into clamp A and the scraper blade. At this time, connect the fixing pin to clamp B through thread to complete the replacement of the scraper blade. The design of clamp A, clamp B and bidirectional screw rod B makes it easy to replace the scraper blade, avoiding the need for maintenance personnel to use disassembly tools when replacing the scraper blade. The design of the fixing pin also prevents the scraper blade from shifting when it is under force for a long time when the scraper blade is working. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In this embodiment, the fixed seat A106 and the fixed seat B107 can be installed on the coating machine through the insert 210 on the fixed seat A106 and the fixed seat B107. When adjusting the distance between the fixed seat A106 and the fixed seat B107, the fixed seat A106 and the fixed seat B107 will drive the fixed frame 200 on the movable seat A102 and the movable seat B103 to move. At this time, the fixed frame 200 will drive the rotating shaft A201 to slide on the surface of the turning handle 202, so that the limit block 203 slides in the limit groove 204, thereby completing the adjustment of the distance between the fixed seat A106 and the fixed seat B107;

[0039] By rotating the handle 202, the handle 202 will drive the rotating shaft A201 to rotate through the limit block 203 and the limit groove 204, and the rotating shaft A201 will drive the bevel gear A205 to rotate, and the bevel gear A205 will drive the rotating shaft B206 to rotate through the bevel gear B207.

[0040] Embodiment 3: According to Figure 9-11As shown, the scraper mechanism 300 includes a scraper blade 301, a limit plate A302 and a limit plate B303, the limit plate A302 is internally connected to a clamping plate A304 and a clamping plate B308 in a sliding manner, the limit plate A302 is internally connected to a bidirectional screw rod B307 for rotation, the limit plate B303 is internally fixedly installed with a limit rod B306, the clamping plate A304 is internally inserted with a fixing pin 305, the clamping plate A304 and the clamping plate B308 are both connected to the fixing plate B and the limit rod B 306 are slidingly connected, splint A304 and splint B308 are connected to the bidirectional screw rod B307 by threads, soft pads 309 are fixedly installed on the surfaces of splint A304 and splint B308, and the material of soft pads 309 is natural rubber, the scraper blade 301 is slidingly connected to the splint A304 and splint B308, the fixing pin 305 is connected to the splint B308 by threads, and the fixing pin 305 is slidingly connected to the scraper blade 301.

[0041] In this embodiment, by rotating the fixing pin 305, the fixing pin 305 can be pulled out from the scraper blade 301 and the splint A304 after the fixing pin 305 is rotated out of the splint B308. At this time, the bidirectional screw rod B307 is rotated again. When the bidirectional screw rod B307 rotates, it will drive the splint A304 and the splint B308 to move laterally inside the limit plate A302. At this time, the splint A304 and the splint B308 will also move laterally inside the limit rod B306 and the limit plate B303. When the splint A304 and the splint B308 are away from the scraper blade 301, the scraper blade 301 can be pulled out from the splint A304 and the splint B308, and then the new scraper blade 301 can be inserted between the splint A304 and the splint B308. Rotate the bidirectional screw rod B307 in the direction of rotation, so that the clamp plate A304 and the clamp plate B308 clamp and fix the scraper blade 301. After the soft pad 309 fits tightly against the scraper blade 301, insert the fixing pin 305 into the clamp plate A304 and the scraper blade 301. At this time, the fixing pin 305 is connected to the clamp plate B308 through a thread to complete the replacement of the scraper blade 301. The design of the clamp plate A304, the clamp plate B308 and the bidirectional screw rod B307 facilitates the replacement of the scraper blade 301, avoiding the need for maintenance personnel to use disassembly tools when replacing the scraper blade 301. The design of the fixing pin 305 also prevents the scraper blade 301 from deviating when it is under force for a long time when the scraper blade 301 is working.

[0042] The method of use and working principle of the device: When the scraper mechanism 300 needs to be disassembled, assembled or replaced, first pull the handle 110, and then the handle 110 will drive the fixed seat A106 to slide on the surface of the movable seat A102, and will also slide on the surface of the limit rod A111, and then the fixed seat A106 will drive the fixed block A109 to move horizontally, and after the plug block 108 slides out from the inside of the fixed block A109, the scraper mechanism 300 can be removed from the fixed seat B107. The fixed block B113 is pulled out, and the new scraper mechanism 300 is inserted into the fixed block B113 through the insert block 108. Then the insert block 108 at the other end of the scraper mechanism 300 is aligned with the fixed block A109 and the pull handle 110 is released. At this time, the fixed seat A106 slides on the surface of the limit rod A111 and the movable seat A102 under the elastic force of the spring 112. When the insert block 108 is inserted into the fixed block A109, the scraper mechanism 300 can be disassembled and replaced.

[0043] When the angle of the scraper mechanism 300 needs to be adjusted, the paddle 120 is first moved, and the paddle 120 drives the slide bar A116 to slide inside the movable seat B103 through the connecting rod 118, and the connecting rod 118 drives the fixed rod 119 to slide out of the fixed hole 115. At this time, the rotating disk 114 is rotated, and the rotating disk 114 drives the scraper mechanism 300 and the fixed block A109 to rotate in the fixed seat A106 through the fixed block B113 and the plug block 108, thereby completing the adjustment of the scraper mechanism 300;

[0044] When the fixed seat A106 and the fixed seat B107 need to be installed, the fixed seat A106 and the fixed seat B107 can be installed on the coating machine only through the insert strips 210 on the fixed seat A106 and the fixed seat B107. When adjusting the distance between the fixed seat A106 and the fixed seat B107, the fixed seat A106 and the fixed seat B107 will drive the fixing frame 200 on the moving seat A102 and the moving seat B103 to move. At this time, the fixing frame 200 will drive the rotating shaft A201 to slide on the surface of the turning handle 202, so that the limiting block 203 slides in the limiting groove 204, thereby completing the adjustment of the distance between the fixed seat A106 and the fixed seat B107;

[0045] When the scraper blade 301 needs to be disassembled, assembled or replaced, the handle 202 is first rotated. When the handle 202 is rotated, it will drive the shaft A201 to rotate through the limit block 203 and the limit groove 204, and the shaft A201 will drive the bevel gear A205 to rotate, and the bevel gear A205 will drive the shaft B206 to rotate through the bevel gear B207. When the shaft B206 rotates, it will drive the fixed frame 200 through the screw rod A208 to drive the moving seat A102 and the moving seat B103 to slide inside the fixed seat A106 and the fixed seat B107. At this time, the moving seat A102 and the moving seat B103 will move up and down along the limit rod B306, thereby completing the up and down adjustment of the scraper mechanism 300. The adjustable spacing design of the fixed seat A106 and the fixed seat B107 makes the scraper adjustment mechanism suitable for different models of coating machines, thereby improving the adaptability of the scraper adjustment mechanism, making it convenient to apply and scrape materials of different widths.

[0046] By rotating the fixing pin 305, the fixing pin 305 can be pulled out from the scraper blade 301 and the clamping plate A304 after the fixing pin 305 is rotated out of the clamping plate B308. At this time, the bidirectional screw rod B307 is rotated again. When the bidirectional screw rod B307 rotates, it will drive the clamping plate A304 and the clamping plate B308 to move horizontally inside the limit plate A302. At this time, the clamping plate A304 and the clamping plate B308 will also move horizontally inside the limit rod B306 and the limit plate B303. When the clamping plate A304 and the clamping plate B308 are away from the scraper blade 301, Pull out the scraper blade 301 from the clamp A304 and the clamp B308, and then insert the new scraper blade 301 between the clamp A304 and the clamp B308, and rotate the two-way screw rod B307 in the opposite direction so that the clamp A304 and the clamp B308 clamp and fix the scraper blade 301.
