Description

Technical Field

[0001] This utility model relates to the field of carbon ribbon technology, specifically to a high heat-resistant carbon ribbon ink coating device. Background Technology

[0002] The high heat-resistant ribbon ink coating device is mainly used to coat the ribbon base film with ink with high heat resistance to produce high-quality ribbons suitable for thermal transfer printing.

[0003] A search revealed a Chinese utility model patent, CN221493089U, which discloses a high-heat-resistant carbon ribbon ink coating device, belonging to the technical field of ink coating equipment. This device includes a replenishment unit comprising a storage tank fixedly connected to the bottom of a housing. A collection port is located on the top side of the storage tank, and a valve is located on one side of the storage tank. A waterproof sleeve is fixedly connected inside the storage tank, and an ink pump is fixedly connected inside the waterproof sleeve. A water pipe is fixedly connected to the output end of the ink pump. This application utilizes a replenishment mechanism that allows ink to be supplied to the ink tank during use, avoiding the need for manual refilling when the ink level is low, thereby improving the device's performance.

[0004] However, the device lacks the function of meeting the requirements of coating base film of different thicknesses and different coating thicknesses. During use, the roller spacing at the inlet and outlet is fixed and cannot be adjusted, and it can only adapt to carbon ribbon base film of one thickness specification. Although the device uses a scraper to remove excess ink, the scraper spacing is fixed and cannot be adjusted, and it can only meet the requirements of one coating thickness. The above two points result in the narrow applicability of the device. Utility Model Content

[0005] The purpose of this invention is to provide a high heat-resistant carbon ribbon ink coating device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high heat-resistant carbon ribbon ink coating device includes a housing with an inlet and an outlet on both sides. Several fixed plates are fixedly connected to the inner wall of the housing. A bidirectional lead screw is rotatably connected to the top of each fixed plate. A slider is sleeved on the outer surface of the bidirectional lead screw. A sliding cylinder is threaded to the top of the bidirectional lead screw. A connecting rod is fixedly connected to the top of the sliding cylinder. An electric telescopic rod is fixedly connected to the top of the center of the connecting rod. A second fixed plate is fixedly connected to the inner wall of the housing near the first fixed plate. A second bidirectional lead screw is rotatably connected to the top of the second fixed plate. A long plate is sleeved on the outer surface of the second bidirectional lead screw. A sliding cylinder is threaded to the top of the second bidirectional lead screw. An electric telescopic rod is fixedly connected to the top of the sliding cylinder.

[0008] Preferably, a motor is fixedly connected to the outer surface of one of the four sets of sliders, an active roller is fixedly connected to the output shaft of the motor, a conveyor belt is slidably connected to the outer surface of the active roller, a driven roller is slidably connected to the side of the conveyor belt away from the active roller, an ink pool is fixedly connected to the bottom of the housing, and several guide rollers are rotatably connected to the inner wall of the housing near the ink pool.

[0009] Preferably, a scraper is fixedly connected to the outer surface of the long plate, a bent tube is inserted into the ink pool, and a collection box is fixedly connected to the top of the bent tube.

[0010] Preferably, a double-headed electric push rod is fixedly connected to the inner wall of the curved tube, a spring is fixedly connected to the end of the double-headed electric push rod near the collection box, and a scraper is fixedly connected to the end of the spring away from the ink pool.

[0011] Preferably, a threaded rod is fixedly connected to the end of the dual-headed electric push rod away from the spring, and a long cylinder is sleeved on the outer surface of the threaded rod away from the dual-headed electric push rod. A plurality of stirring fans are fixedly connected to the end of the long cylinder away from the threaded rod.

[0012] Preferably, one of the two long plates has several grooves, and the collection box and the central axis of the long plate are located on the same vertical plane.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This high-heat-resistant carbon ribbon ink coating device, through the arrangement of electric telescopic rod one, electric telescopic rod two, slide cylinder one, slide cylinder two, bidirectional lead screw one, and bidirectional lead screw two, allows for the following operation: A carbon ribbon base film is placed in the device, and the motor is started to drive the active roller to rotate, which in turn drives the driven roller and guide roller to rotate, causing the base film to continuously pass through the ink pool and then be pulled out from the outlet. Electric telescopic rod one is then activated, causing slide cylinder one to move vertically, which in turn drives bidirectional lead screw one to rotate, causing the two externally sleeved sliders to move in opposite directions. All four sets of sliders move simultaneously, causing the two active rollers to move closer or further apart, and the driven rollers to move in the same way. Electric telescopic rod two is then activated, causing slide cylinder two to move vertically, which in turn drives bidirectional lead screw two to rotate, causing the two long plates to move closer or further apart. By controlling the distance between the two active rollers, two driven rollers, and two long plates through electric telescopic rods one and two, the device can meet the needs of coating base films of different thicknesses and different coating thicknesses, thus expanding its applicability.

[0015] 2. This high-heat-resistant carbon ribbon ink coating device, through the arrangement of a double-headed electric push rod, a scraper, and a stirring fan, allows the coated carbon ribbon base film to be moved between two long plates with the assistance of a driven roller during use. The scraper on the long plates scrapes off excess ink from the surface of the carbon ribbon base film, and the excess ink falls into a collection box and returns to the ink pool through a bend. Activating the double-headed electric push rod drives a spring to move back to its original position within the bend. Due to the spring's flexibility, it causes the scraper to scrape against the inner wall of the bend, preventing ink adhesion and blockage inside the bend. Simultaneously, the double-headed electric push rod drives a threaded rod to move back to its original position, causing the long cylinder to rotate reciprocally, which in turn causes the stirring fan to rotate reciprocally in the ink pool, preventing ink sedimentation at the bottom of the ink pool. The arrangement of the scraper and stirring fan improves the coating quality. Attached Figure Description

[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 Figures 1-5As shown, this utility model provides a technical solution:

[0024] A high heat-resistant carbon ribbon ink coating device includes a housing 1. An inlet 2 and an outlet 3 are respectively opened on both sides of the housing 1. Several fixed plates 4 are fixedly connected to the inner wall of the housing 1. A bidirectional lead screw 5 is rotatably connected to the top of each fixed plate 4. A slider 6 is sleeved on the outer surface of the bidirectional lead screw 5. A slide cylinder 7 is threadedly connected to the top of the bidirectional lead screw 5. A connecting rod 8 is fixedly connected to the top of the slide cylinder 7. An electric telescopic rod 9 is fixedly connected to the top of the center of the connecting rod 8. A second fixed plate 10 is fixedly connected to the inner wall of the housing 1 near the fixed plates 4. A bidirectional lead screw 11 is rotatably connected to the top of the second fixed plate 10. A long plate 12 is sleeved on the outer surface of the bidirectional lead screw 11. A slide cylinder 13 is threadedly connected to the top of the bidirectional lead screw 11. An electric telescopic rod 14 is fixedly connected to the top of the slide cylinder 13. During use... The electric telescopic rod 9 is activated, causing the slide cylinder 7 to move vertically, which in turn causes the bidirectional lead screw 5 to rotate, causing the two externally sleeved sliders 6 to move in opposite directions. The four sets of sliders 6 move simultaneously, causing the distance between the two active rollers 16 to increase or decrease. The same applies to the driven rollers 18. The electric telescopic rod 14 is activated, causing the slide cylinder 13 to move vertically, which in turn causes the bidirectional lead screw 11 to rotate, causing the two long plates 12 to move closer or further apart. Through the electric telescopic rods 9 and 14, the distance between the two active rollers 16, the two driven rollers 18, and the two long plates 12 is controlled, thereby meeting the needs of different thickness carbon ribbon base film coating and different coating thicknesses. This changes the situation where the traditional rotating roller spacing is fixed and can only process one type of carbon ribbon base film. In addition, the scraper 21 is added to recover excess ink while controlling the thickness of the ink coating.

[0025] In this embodiment, preferably, a motor 15 is fixedly connected to the outer surface of one of the four sets of sliders 6, an active roller 16 is fixedly connected to the output shaft of the motor 15, a conveyor belt 17 is slidably connected to the outer surface of the active roller 16, a driven roller 18 is slidably connected to the side of the conveyor belt 17 away from the active roller 16, an ink pool 19 is fixedly connected to the bottom of the housing 1, and several guide rollers 20 are rotatably connected to the inner wall of the housing 1 near the ink pool 19. In use, the carbon ribbon base film is placed, the motor 15 is started to drive the active roller 16 to rotate, which drives the driven roller 18 and the guide roller 20 to rotate, causing the carbon ribbon base film to continuously pass through the ink pool 19 and then be pulled out from the discharge port 3. The carbon ribbon base film is passed through the active roller 16, wrapped around the guide roller 20, and then passed through the driven roller 18, thus completing the base film coating process.

[0026] In this embodiment, preferably, a scraper 21 is fixedly connected to the outer surface of the long plate 12, and a bent tube 22 is inserted into the ink pool 19. A collection box 23 is fixedly connected to the top of the bent tube 22. In use, after coating, the carbon ribbon base film is moved between the two long plates 12 with the help of the driven roller 18. The scraper 21 on the long plate 12 scrapes off the excess ink on the surface of the carbon ribbon base film. The excess ink falls into the collection box 23 and returns to the ink pool 19 through the bent tube 22, thus collecting the excess ink, saving resources, and improving utilization.

[0027] In this embodiment, preferably, a double-headed electric push rod 24 is fixedly connected to the inner wall of the bent tube 22. A spring 25 is fixedly connected to one end of the double-headed electric push rod 24 near the collection box 23, and a scraper 26 is fixedly connected to the other end of the spring 25 away from the ink pool 19. In use, after coating, the carbon ribbon base film is moved between the two long plates 12 with the assistance of the driven roller 18. The scraper 21 on the long plate 12 scrapes off the excess ink on the surface of the carbon ribbon base film. The excess ink falls into the collection box 23 and returns to the ink pool 19 through the bent tube 22. The electric push rod 24 drives the spring 25 to move back and forth inside the bend 22. Since the spring 25 has a certain degree of flexibility, it drives the scraper 26 to scrape the inner wall of the bend 22 to prevent ink from adhering and clogging inside the bend 22. Because the ink is highly concentrated and viscous, it is easy to adhere and deposit on the inner wall of the bend 22 when passing through it. Over time, the ink on the inner wall of the bend 22 will oxidize and deteriorate. If the recovered ink is recycled back into the ink pool 19 after the deteriorated ink has passed through it, it will stain the ink and affect the coating quality of the base film on the ink-carbon tape.

[0028] In this embodiment, preferably, a threaded rod 27 is fixedly connected to the end of the double-headed electric push rod 24 away from the spring 25. A long cylinder 28 is sleeved on the outer surface of the threaded rod 27 away from the double-headed electric push rod 24. A plurality of stirring fans 29 are fixedly connected to the end of the long cylinder 28 away from the threaded rod 27. In use, the double-headed electric push rod 24 drives the threaded rod 27 to move back and forth, drives the long cylinder 28 to rotate back and forth, and drives the stirring fans 29 to rotate back and forth in the ink pool 19 to stir, so as to avoid ink sedimentation at the bottom of the ink pool 19. The coating quality is improved by setting up the doctor blade 26 and the stirring fans 29.

[0029] In this embodiment, preferably, one of the two long plates 12 has several grooves 30. The collection box 23 and the central axis of the long plate 12 are located on the same vertical plane. When in use, the scraper 21 scrapes the excess ink on the surface of the carbon ribbon base film. The ink flows down from the grooves 30, falls into the collection box 23, and then flows into the ink pool 19 through the bend 22. The grooves 30 are designed to guide the ink flow and facilitate the precise flow of ink into the collection box 23.

[0030] Working Principle: In this embodiment, a high heat-resistant carbon ribbon ink coating device is used by placing a carbon ribbon base film, starting the motor 15 to drive the active roller 16 to rotate, which in turn drives the driven roller 18 and guide roller 20 to rotate, causing the carbon ribbon base film to continuously pass through the ink pool 19 and then be pulled out from the discharge port 3. Then, the electric telescopic rod 19 is activated, causing the slide cylinder 7 to move vertically, which in turn drives the bidirectional lead screw 5 to rotate, causing the two externally sleeved sliders 6 to move in opposite directions. All four sets of sliders 6 move simultaneously, causing the distance between the two active rollers 16 to increase or decrease. The driven roller 18 moves similarly. Then, the electric telescopic rod 24 is activated, causing the slide cylinder 23 to move vertically, which in turn drives the bidirectional lead screw 21 to rotate, causing the two long plates 12 to move closer or further apart. This movement is achieved through the electric telescopic rod 19 and the electric... The telescopic rod 14 controls the spacing between the two active rollers 16, the two driven rollers 18, and the two long plates 12. After coating, the carbon ribbon base film is moved between the two long plates 12 with the assistance of the driven rollers 18. The scraper 21 on the long plate 12 scrapes off the excess ink on the surface of the carbon ribbon base film. The excess ink falls into the collection box 23 and returns to the ink pool 19 through the bent tube 22. The double-headed electric push rod 24 is activated, which drives the spring 25 to move back and forth in the bent tube 22. Since the spring 25 has a certain degree of bending, it drives the scraper 26 to scrape the inner wall of the bent tube 22 to prevent ink from adhering and clogging inside the bent tube 22. At the same time, the double-headed electric push rod 24 drives the threaded rod 27 to move back and forth, which drives the long cylinder 28 to rotate back and forth, and drives the stirring fan 29 to rotate back and forth in the ink pool 19 to stir, preventing ink from settling at the bottom of the ink pool 19.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
