Description

Technical Field

[0001] This utility model relates to the field of carbon ribbon cleaning technology, and more specifically to a self-cleaning device for the tail of a carbon ribbon. Background Technology

[0002] A ribbon is a printing consumable required by printing equipment. During use, the tail of the ribbon is fed out and then pressed by the print head to imprint ink onto the paper. However, the ribbon is prone to accumulating dust and impurities after it is fed out, which affects the printing quality. Therefore, the tail of the ribbon needs to be cleaned.

[0003] A search revealed an existing patent (publication number: CN220742532U) that discloses a self-cleaning device for the tail of a carbon ribbon. During use, the carbon ribbon winding drives a cleaning sponge roller to clean the tail of the ribbon. Simultaneously, a micro-pump draws alcohol from an alcohol box, which is sprayed onto the cleaning sponge roller through a spray nozzle, removing dust and impurities from the carbon ribbon. Moving the locking lever upwards away from the locking hole and then rotating the adjusting rod causes the gear to rotate. The gear meshes with a rack, allowing the rack to move up and down for adjustment. This causes the hinge rod to tilt the cleaning sponge roller on one side of the adjusting frame downwards or upwards, pressing it firmly onto the carbon ribbon, thus solving the problem of poor cleaning effect. However, the inventors discovered the following problem with the existing technology during the development of this invention: While the aforementioned self-cleaning device for the tail of the carbon ribbon improves the cleaning effect by spraying alcohol, some alcohol remains on the surface of the ribbon. This residual alcohol affects print quality and reduces printing accuracy.

[0004] In view of this, this utility model proposes a self-cleaning device for the tail of a carbon ribbon. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a carbon ribbon tail self-cleaning device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a self-cleaning device for the tail of a carbon ribbon, including a housing, which is mounted on the top of an external printing device. The bottom side of the housing has an opening for external printing paper to pass through. Inside the housing, a take-up roller and an unwind roller are respectively installed. The surfaces of the take-up roller and the unwind roller are wound with carbon ribbon strips. Two guide rollers are horizontally rotatably installed on the bottom side of the inner wall of the housing. The carbon ribbon strips are wound around the surfaces of the guide rollers and are close to the printing paper. A print head is provided on the bottom side of the inner wall of the housing. The printing end of the print head corresponds to the position of the horizontal section of the carbon ribbon strip. A cleaning and drying component is provided on the inner wall of the housing corresponding to the carbon ribbon strip.

[0007] The cleaning and drying assembly includes two support rollers rotatably connected to the inner wall of the outer shell. A carbon ribbon is laid on the surface of the support rollers. A beam plate is fixedly installed on the inner wall of the outer shell. A hydraulic rod is embedded in the surface of the beam plate. A connecting seat is fixedly installed at the telescopic end of the hydraulic rod. A mounting frame is fixedly installed on the surface of the connecting seat. From top to bottom, a first drying plate, a cleaning roller, and a second drying plate are respectively arranged on the surface of the mounting frame. A servo motor for driving the cleaning roller to rotate is fixedly installed on the surface of the mounting frame. Both the first and second drying plates have arc surfaces. The arc surfaces of the cleaning roller, the first drying plate, and the second drying plate are in contact with the carbon ribbon. A storage tank is fixedly installed on the surface of the mounting frame. The storage tank contains alcohol. A pump body is fixedly installed on the lower right side of the storage tank. The inlet end of the pump body extends into the interior of the storage tank. An atomizing nozzle is fixedly installed at the outlet end of the pump body, with the outlet end of the atomizing nozzle facing the surface of the carbon ribbon. Heating rods and temperature sensors are embedded in the inner walls of both the first and second drying plates.

[0008] Furthermore, a control panel is fixedly installed on the outer wall of the housing, and the control panel is electrically connected to the power supply of an external printing device via wires.

[0009] As a further description of the above technical solution: By setting a control panel, the control panel is used to control the opening and closing of the hydraulic rod, servo motor, heating rod and pump body. The heating temperature of the first drying plate and the second drying plate, as well as the spraying frequency of the pump body and other parameters can be set through the control panel, so that the carbon belt tail self-cleaning device can be flexibly adjusted according to actual needs.

[0010] Furthermore, the servo motor drives the cleaning roller to rotate in the opposite direction to the conveying direction of the carbon fiber strip.

[0011] Furthermore, the connecting seat includes a seat body and a telescopic column. The telescopic column is slidably installed inside the telescopic groove at the end of the seat body, and the inner wall of the telescopic groove is provided with a buffer spring for driving the telescopic column to move outward from the seat body.

[0012] As a further description of the above technical solution: In this carbon belt tail self-cleaning device, the telescopic column of the connecting seat always tends to move outward under the elastic force of the buffer spring, so that the mounting frame can always keep in contact with the carbon belt, ensuring the cleaning and drying effect of the cleaning roller, the first drying plate and the second drying plate on the carbon belt.

[0013] Furthermore, a scraper and a slag collection box are fixedly installed on the surface of the mounting frame, with the scraper abutting against the surface of the cleaning roller, and the slag inlet of the slag collection box corresponding to the position of the scraper.

[0014] As a further description of the above technical solution: by setting a scraper, the surface of the cleaning roller is scraped by the scraper, and the impurities attached to the surface of the cleaning roller are scraped off and collected inside the slag collection box, so as to avoid the impurities affecting the cleaning effect of the cleaning roller.

[0015] Furthermore, a limiting slide rod is fixedly installed on the surface of the connecting seat, and the limiting slide rod is slidably connected to the beam plate.

[0016] As a further description of the above technical solution: by setting a limit slide bar, the movement path of the connecting seat can be restricted and guided, thereby ensuring the stability of the connecting seat when it moves.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. Compared with existing technologies, this ribbon tail self-cleaning device, during the use of external printing equipment, drives the ribbon to wind out through the rotation of the unwinding and rewinding rollers, and prints through the print head. While the ribbon is winding out, a cleaning and drying component is set up. Alcohol from the storage tank is sprayed onto the surface of the ribbon through a pump and atomizing nozzle. Then, a cleaning roller wipes the alcohol-sprayed ribbon to ensure cleaning effect. During the cleaning process, the ribbon is preheated by the first drying plate and the tail of the ribbon is dried by the second drying plate to prevent alcohol residue from affecting subsequent printing. When the heating rod is powered on to generate heat to heat the first and second drying plates, a temperature sensor detects the temperature of the first and second drying plates in real time and transmits the temperature signal to the control panel. When the temperature exceeds the preset value, the control panel controls the heating rod to cut off the power to prevent the ribbon from being damaged by overheating.

[0019] 2. Compared with the prior art, this carbon ribbon tail self-cleaning device features a control panel that controls the opening and closing of the hydraulic rod, servo motor, heating rod, and pump. The control panel allows for setting parameters such as the heating temperature of the first and second drying plates, and the spraying frequency of the pump, enabling flexible adjustment according to actual needs. Furthermore, a scraper is used to scrape the surface of the cleaning roller, removing impurities that adhere to the roller surface and collecting them in the slag collection box, thus preventing impurities from affecting the cleaning effect of the cleaning roller.

[0020] 3. Compared with the prior art, the self-cleaning device for the carbon ribbon tail has a tendency for the telescopic column of the connector to move outward under the elastic force of the buffer spring, so that the mounting frame can always keep in contact with the carbon ribbon, ensuring the cleaning and drying effect of the cleaning roller, the first drying plate and the second drying plate on the carbon ribbon; by setting the limiting slide bar, the movement path of the connector can be restricted and guided, thereby ensuring the stability of the connector when moving.

In addition, the forms of the various structures described in the following embodiments are merely illustrative. The carbon ribbon tail self-cleaning device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Reference Figures 1 to 5 This utility model provides a self-cleaning device for the tail of a carbon ribbon, including a housing 1, which is mounted on the top of an external printing device. A control panel 20 is fixedly installed on the outer wall of the housing 1, and the control panel 20 is electrically connected to the power supply of the external printing device through a wire.

[0029] By setting the control panel 20, the self-cleaning device at the tail of the ribbon can be flexibly adjusted according to actual needs.

[0030] The bottom side of the outer casing 1 has an opening for external printing paper to pass through. Inside the outer casing 1, a take-up roller 2 and an unwind roller 3 are installed respectively. Carbon ribbon is wound on the surface of the take-up roller 2 and the unwind roller 3. Two guide rollers 4 are installed horizontally on the bottom side of the inner wall of the outer casing 1. The carbon ribbon is wound around the surface of the guide rollers 4 and is close to the printing paper. A print head 5 is provided on the bottom side of the inner wall of the outer casing 1. The printing end of the print head 5 corresponds to the position of the horizontal section of the carbon ribbon.

[0031] The self-cleaning device at the tail of the ribbon, during the use of external printing equipment, drives the ribbon to be conveyed and wound out by the rotation of the unwinding roller 3 and the take-up roller 2, and then performs the printing action through the print head 5.

[0032] A cleaning and drying component is provided on the inner wall of the outer casing 1 corresponding to the carbon belt.

[0033] The cleaning and drying assembly includes two support rollers 6 rotatably connected to the inner wall of the outer casing 1. Carbon fiber strips are laid on the surface of the support rollers 6. A beam plate 7 is fixedly installed on the inner wall of the outer casing 1. A hydraulic rod 8 is embedded in the surface of the beam plate 7. A connecting seat 9 is fixedly installed at the telescopic end of the hydraulic rod 8. A mounting frame 10 is fixedly installed on the surface of the connecting seat 9. A first drying plate 11, a cleaning roller 12, and a second drying plate 13 are respectively arranged on the surface of the mounting frame 10 from top to bottom. A servo motor 14 that drives the cleaning roller 12 to rotate is fixedly installed on the surface of the mounting frame 10. The rotation direction of the cleaning roller 12 driven by the servo motor 14 is opposite to the conveying direction of the carbon fiber strip.

[0034] The surfaces of the first drying plate 11 and the second drying plate 13 are both provided with arc surfaces. The arc surfaces of the cleaning roller 12, the first drying plate 11 and the second drying plate 13 are all in contact with the carbon ribbon. A storage tank 15 is fixedly installed on the surface of the mounting frame 10. The inside of the storage tank 15 contains alcohol. A pump body 16 is fixedly installed on the lower right side of the storage tank 15. The liquid inlet end of the pump body 16 extends into the inside of the storage tank 15. An atomizing nozzle 17 is fixedly installed on the liquid outlet end of the pump body 16. The liquid outlet end of the atomizing nozzle 17 faces the surface of the carbon ribbon. The inner walls of the first drying plate 11 and the second drying plate 13 are both embedded with heating rods 18 and temperature sensors 19.

[0035] During the ribbon winding process, a cleaning and drying assembly is used to spray alcohol from the tank 15 onto the surface of the ribbon via the pump body 16 and the atomizing nozzle 17. Then, the cleaning roller 12 is used to wipe and clean the ribbon sprayed with alcohol to ensure cleaning effectiveness. During the cleaning process, the ribbon is preheated by the first drying plate 11, and the tail of the ribbon is dried by the second drying plate 13 to prevent alcohol residue from remaining on the surface of the ribbon and affecting subsequent printing work.

[0036] It is worth noting that when the heating rod 18 is powered on to generate heat to heat the first drying plate 11 and the second drying plate 13, the temperature sensor 19 is used to detect the temperature of the first drying plate 11 and the second drying plate 13 in real time and transmit the temperature signal to the control panel 20. When the temperature is higher than the preset value, the control panel 20 controls the heating rod 18 to cut off the power to avoid the carbon ribbon from being damaged due to excessive temperature.

The telescopic column 902 is slidably installed inside the telescopic groove at the end of the seat body 901, and the inner wall of the telescopic groove is provided with a buffer spring 903 for driving the telescopic column 902 to move outward from the seat body 901.

[0038] Furthermore, in this carbon ribbon tail self-cleaning device, the telescopic column 902 of the connecting seat 9 always tends to move outward from the seat body 901 under the elastic force of the buffer spring 903, so that the mounting frame 10 can always keep in contact with the carbon ribbon, ensuring the cleaning and drying effect of the cleaning roller 12, the first drying plate 11 and the second drying plate 13 on the carbon ribbon.

[0039] Scraper 21 and slag collection box 22 are fixedly installed on the surface of mounting frame 10. Scraper 21 is in close contact with the surface of cleaning roller 12, and the slag inlet of slag collection box 22 corresponds to the position of scraper 21.

[0040] Furthermore, by setting up a scraper 21, the surface of the cleaning roller 12 is scraped by the scraper 21, and the impurities attached to the surface of the cleaning roller 12 are scraped off and collected inside the slag collection box 22, so as to avoid the impurities affecting the cleaning effect of the cleaning roller 12.

[0041] A limiting slide rod 23 is fixedly installed on the surface of the connecting seat 9, and the limiting slide rod 23 is slidably connected to the beam plate 7.

[0042] Furthermore, by setting the limiting slide bar 23, the movement path of the connecting seat 9 can be restricted and guided, thereby ensuring the stability of the connecting seat 9 when it moves.

[0043] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
