Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a coating machine with a cleaning function. Background Art

[0002] A coating machine is a device that coats a rolled substrate with a layer of glue, paint or ink with specific functions, dries it, and then rewinds it. It is mainly used in the surface coating process production of films, paper, etc.

[0003] However, the existing coating machine cannot clean the surface of the coating roller in time, so it is impossible to ensure that the coating adheres evenly to the outer side of the coating roller.

[0004] For example, a coating machine with a cleaning function disclosed in Chinese patent CN218554614U drives a first movable block to rotate through a motor, so that a second movable block meshing with the first movable block rotates, thereby causing a coating roller fixedly connected to the second movable block to rotate inside a coating placement box, thereby causing the coating roller to be covered with paint inside the coating placement box, and causing the scraping brush provided on the rear side of the fixed block to sweep excess paint from the outside of the coating roller into the inside of the coating placement box, thereby facilitating uniform coating of the substrate.

[0005] However, the coating roller on the coater cannot be adjusted, so that substrates of different thicknesses cannot be coated.

[0006] For this reason, we urgently need to provide an adjustable coating machine with a cleaning function. Utility Model Content

[0007] The utility model aims to provide a coating machine with a cleaning function to solve the problem in the above background technology that the coating roller on the coating machine cannot be adjusted, thereby being unable to coat substrates of different thicknesses.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coater with a cleaning function, comprising a coater main body and a frame, the frame is fixedly connected to the left side of the coater main body, the lower end of the inner part of the frame is rotatably connected to a discharge roller, the upper end of the coater main body is rotatably connected to a limiting roller on the left, the outer ends of the coater main body and the frame are connected to a coating mechanism, the coating mechanism comprises a coating unit and a cleaning unit, the coating unit is arranged at the outer ends of the coater main body and the frame, and the cleaning unit is arranged at the upper end of the frame.

[0009] The coating unit includes a bottom rod, a guide rail, a sliding plate, a first support member, a second support member, a material transfer roller, a coating roller, a support platform, a motor, a connecting rod, a sleeve, a support plate, a bearing, a threaded rod, a rotating handle and a material storage box. The bottom rod is fixedly connected to the front and rear ends of the upper side of the frame, the guide rail is fixedly connected to the upper side of the bottom rod, the sliding plate is connected to the upper end of the bottom rod, the first support member is fixedly connected to the upper right end of the sliding plate, the second support member is fixedly connected to the upper left end of the sliding plate, and the material transfer roller is rotatably connected between the second support members. The coating roller is rotatably connected between the first support members, the support platform is arranged at the rear end of the frame, the motor is slidably connected to the upper end of the support platform, the connecting rod is fixedly connected to the right end of the output shaft of the motor, the sleeve is fixedly connected to the left lower end of the second support member, the support plate is fixedly connected to the upper left end of the bottom rod, the bearing is fixedly connected to the inner upper end of the support plate, the threaded rod is fixedly connected to the inner side of the bearing, the rotating handle is fixedly connected to the left end of the threaded rod, and the storage box is fixedly connected to the lower end of the adjacent side of the two bottom rods.

[0010] A further improvement is that there are two motors connected to the support platform, and the output shafts of the two motors rotate in opposite directions, and the front end of the connecting rod is fixedly connected to the rear ends of the feed roller and the coating roller, respectively. Thus, when the output shaft of the motor is started and rotated to drive the connecting rod to rotate, the feed roller and the coating roller rotate relative to each other, at which time the feed roller rotates clockwise and the coating roller rotates counterclockwise, the feed roller contacts the paint in the storage box and then transfers it to the outside of the coating roller, and then contacts the surface of the substrate at the right end to complete the coating of the substrate.

[0011] A further improvement is that a slide groove is provided at the lower end of the sliding plate, and the outer side of the guide rail is slidably connected to the inner side of the slide groove, so that when the sliding plate moves, it can only slide along the outer side of the guide rail, thereby limiting the movement of the sliding plate and the transfer roller and coating roller at the upper end thereof.

[0012] A further improvement is that the inner side of the sleeve is provided with an internal thread, and the outer side of the threaded rod is threadedly connected to the inner side of the sleeve. Thus, when the rotating handle is turned to drive the threaded rod located inside the sleeve to rotate, the sleeve and the threaded rod can move relative to each other, thereby driving the second support member to move, and at the same time the sliding plate moves along the outer side of the guide rail, so that the position of the coating roller can be adjusted to facilitate contact with substrates of different thicknesses.

[0013] A further improvement is that the cleaning unit includes a rectangular rod and a scraper, the rectangular rod is fixedly connected to the front and rear ends of the upper side of the storage box, and the scraper is connected to the upper end of one adjacent side of the two rectangular rods.

[0014] A further improvement is that the right end of the outer side of the scraper is slidably connected to the outer side of the material transfer roller. Therefore, when the material transfer roller continues to rotate to the right end of the scraper after contacting the coating roller, the right end of the scraper will scrape off the excess paint on the outer side of the material transfer roller, preventing the material transfer roller from repeatedly contacting the paint in the material storage box, resulting in uneven paint on the outer side of the material transfer roller, and uneven paint transferred to the outer side of the coating roller, thereby causing uneven coating of the substrate.

[0015] A further improvement is that a circular hole is formed at the upper end of the rectangular rod, and a threaded groove is formed at the front and rear sides of the left end of the scraper. The scraper can be fixed between the rectangular rods by passing a bolt through the circular hole at the upper end of the rectangular rod and then threadedly connected to the threaded grooves at the front and rear ends of the scraper. The scraper can also be removed from between the rectangular rods by rotating the bolt to remove it from the threaded groove, so that the scraper can be replaced when it is damaged.

[0016] In summary, the present application discloses a coating machine with a cleaning function.

[0017] This technical solution enables the sleeve and the threaded rod to move relative to each other when the rotating handle drives the threaded rod located inside the sleeve to rotate, thereby driving the second support member to move. At the same time, the sliding plate moves along the outer side of the guide rail, so that the position of the coating roller can be adjusted to facilitate contact with substrates of different thicknesses.

[0018] Furthermore, by providing a scraper on the material storage box, when the transfer roller continues to rotate to the right end of the scraper after contacting the coating roller, the right end of the scraper will scrape off the excess paint on the outside of the transfer roller, preventing the transfer roller from repeatedly contacting the paint in the material storage box, resulting in uneven paint on the outside of the transfer roller, which in turn causes uneven transfer of paint to the outside of the coating roller, thereby causing uneven coating of the substrate.

[0028] The coating unit includes a bottom rod 501, a guide rail 502, a sliding plate 503, a first support member 504, a second support member 505, a material transfer roller 506, a coating roller 507, a support platform 508, a motor 509, a connecting rod 510, a sleeve 511, a support plate 512, a bearing 513, a threaded rod 514, a rotating handle 515 and a material storage box 516. The bottom rod 501 is fixedly connected to the front and rear ends of the upper side of the frame 2, and the guide rail 502 is fixedly connected to the bottom rod 50 1, the sliding plate 503 is connected to the upper end of the bottom rod 501, the first support member 504 is fixedly connected to the upper right end of the sliding plate 503, the second support member 505 is fixedly connected to the upper left end of the sliding plate 503, the material transfer roller 506 is rotatably connected between the second support members 505, the coating roller 507 is rotatably connected between the first support members 504, a slide groove is provided at the lower end of the inner part of the sliding plate 503, and the outer side of the guide rail 502 is slidably connected to the inner side of the slide groove. Therefore, when the sliding plate 503 moves, it can only slide along the outer side of the guide rail 502, thereby limiting the movement of the sliding plate 503 and the material transfer roller 506 and the coating roller 507 at its upper end.

[0029] The support platform 508 is arranged at the rear end of the frame 2, the motor 509 is slidably connected to the upper end of the support platform 508, the connecting rod 510 is fixedly connected to the right end of the output shaft of the motor 509, the sleeve 511 is fixedly connected to the left lower end of the second support member 505, the support plate 512 is fixedly connected to the upper left end of the bottom rod 501, the bearing 513 is fixedly connected to the inner upper end of the support plate 512, the threaded rod 514 is fixedly connected to the inner side of the bearing 513, the rotating handle 515 is fixedly connected to the left end of the threaded rod 514, and the storage box 516 is fixedly connected to the lower end of the adjacent side of the two bottom rods 501.

[0030] There are two motors 509 connected to the support platform 508, and the output shafts of the two motors 509 rotate in opposite directions. The front ends of the connecting rods 510 are respectively fixedly connected to the rear ends of the feed roller 506 and the coating roller 507. Thus, when the motor 509 is started, the output shaft thereof rotates to drive the connecting rod 510 to rotate, and the feed roller 506 and the coating roller 507 rotate relative to each other. At this time, the feed roller 506 rotates clockwise, and the coating roller 507 rotates counterclockwise.

Therefore, when the material transfer roller 506 continues to rotate to the right end of the scraper 602 after contacting the coating roller 507, the right end of the scraper 602 will scrape off the excess paint on the outer side of the material transfer roller 506 at this time, preventing the material transfer roller 506 from repeatedly contacting the paint in the material storage box 516, resulting in uneven paint on the outer side of the material transfer roller 506, and causing uneven paint transferred to the outer side of the coating roller 507, thereby causing uneven coating of the substrate.

[0034] Embodiment three:

[0035] On the basis of the first embodiment: a circular hole is formed at the upper end of the rectangular rod 601, and a thread groove is formed at the front and rear sides of the left end of the scraper 602. Thus, by passing a bolt through the circular hole at the upper end of the rectangular rod 601 and then threading it into the thread grooves at the front and rear ends of the scraper 602, the scraper 602 can be fixed between the rectangular rods 601, and the scraper 602 can be removed from the rectangular rods 601 by rotating the bolt to remove it from the thread groove, so that the scraper 602 can be replaced when it is damaged.

[0036] Working principle: When in use, start the coating machine body 1 so that the substrate on the outside of the discharge roller 3 is discharged and moves upward and moves to the right through the limiting roller 4. At the same time, start the two motors 509 on the support platform 508 and rotate their output shafts to cause the feed roller 506 and the coating roller 507 to rotate relative to each other. At this time, the feed roller 506 rotates to contact the paint in the material storage box 516 and then transfers the paint to the outside of the coating roller 507 when contacting the coating roller 507. Then, the coating roller 507 with the paint attached rotates to the left end of the contact substrate, completing the coating of the substrate.
