Description

Technical Field

[0001] The invention belongs to the technical field of dust prevention of printer rubber rollers, and in particular relates to a dust prevention device for the rubber rollers of a thermal desktop barcode printer. Background Art

[0002] A barcode printer is a special printer mainly used to print barcodes, labels, etc. It uses chemically treated thermal media. When the media passes under the thermal print head, the print head heats up and makes the media black, thus forming a pattern. This method does not use ink, toner or ribbon. It is simple and has low operating costs, but the printed content is easy to fade over time.

[0003] The rubber roller slots in common barcode printers are all closed. When used for a long time, dust is easily accumulated in the rubber roller slot, which will affect the printing effect and quality. At the same time, paper scraps are easily entered into the rubber roller slot, and the paper scraps sticking to the rubber roller will produce excessive friction noise, thereby reducing the service life of the rubber roller. In view of this, we propose a thermal desktop barcode printer rubber roller dust prevention device. Summary of the invention

[0004] The object of the present invention is to provide a dustproof device for a rubber roller of a thermal desktop barcode printer to solve the problems raised in the above-mentioned background technology.

[0006] A printer body, wherein a dustproof groove is provided on the printer body, a rotating groove 1 and a rotating groove 2 are provided in the printer body and located on both sides of the dustproof groove, respectively, a same rotating roller is rotatably installed between the rotating groove 1 and the rotating groove 2, a rubber roller body is fixedly installed on the rotating roller and located in the dustproof groove, and a gear is fixedly installed on the rotating roller and located in the rotating groove 2;

[0007] A limiting component, which is located in the printer body and is used to limit the rotating roller;

[0008] Two dust discharge holes, both of which are provided at the bottom of the dustproof groove, a plug-in slot is provided in the printer body and on one side of the two dust discharge holes, a plug-in strip is plugged and installed in the plug-in slot, a cleaning block in contact with the rubber roller body is fixedly installed on the top of the plug-in strip, and a paddle is fixedly installed on the bottom of the plug-in strip and below the plug-in slot;

[0009] The fixing component is located in the printer body and is used to fix the insert strip.

[0010] In the technical scheme, through the dustproof groove, the dust or garbage generated by the rubber roller body during the working process will fall into the dustproof groove, and then, under the action of gravity, the dust or garbage will be discharged to the outside through the two dust discharge holes. At the same time, when the rubber roller body rotates, the peripheral side of the rubber roller body will contact the top of the cleaning block. The cleaning block can clean the dust attached to the surface of the rubber roller body to prevent the dust from being adsorbed on the rubber roller body and affecting the printing effect and quality, which plays a good role in protecting the service life of the rubber roller body and preventing the paper scraps from sticking to the rubber roller body to generate excessive friction noise.

[0011] By setting the fixing component, when the cleaning effect of the cleaning block becomes worse, the personnel can release the fixing of the plug-in strip through the fixing component, and then the personnel can pull the plug-in strip out of the plug-in slot through the paddle. At this time, the personnel can replace the cleaning block on the plug-in strip, and then insert the replaced plug-in strip into the plug-in slot, and then fix the plug-in strip through the fixing component, so as to ensure that the cleaning block can be easily replaced by the personnel and the cleaning block can maintain a good cleaning effect;

[0012] By setting the limit assembly, when the rubber roller body is damaged after long-term use, the personnel can release the limit on the rotating roller through the limit assembly, and then the personnel can take out the rotating roller and the rubber roller body and replace them. After the replacement is completed, the rotating roller can be limited again through the limit assembly, ensuring that it is convenient for personnel to replace the rotating roller and the rubber roller body.

[0013] In the above technical solution, further, the limit assembly includes:

[0014] Two limit plates, the two limit plates are rotatably installed in rotating groove 1 and rotating groove 2 respectively, and the two limit plates are both located at the top of the rotating roller, and sliding grooves are provided in the printer body and on the side away from the two limit plates respectively, and a limit hole 1 is provided on one side of the limit plate, and a limit block is slidably installed in the sliding groove, one end of the limit block passes through one side of the sliding groove and extends into the corresponding limit hole 1, and the other end of the limit block is fixedly installed with a spring 1 fixed to the inner wall of the sliding groove, and a movable plate 1 is fixedly installed on the top of the limit block, and the top of the movable plate 1 passes through the sliding groove and extends to the outside.

[0015] In the technical solution, when the rubber roller body is damaged after long-term use, the personnel can respectively move the two movable plates 1. The movement of the movable plate 1 will drive the limit block to move. The movement of the limit block in the sliding groove will squeeze the spring 1 to shrink until one end of the limit block moves out of the limit hole 1. At this time, the limit block can release the limit on the limit plate, and then the limit plate is rotated again until the two limit plates are rotated 180°. At this time, the two limit plates can release the limit on the rotating roller, and then the personnel can take out the rotating roller and the rubber roller body. And replace it. After the replacement is completed, rotate the two limit plates again. The rotation of the limit plate will squeeze one end of the limit block, so that the limit block moves in the sliding groove and squeezes the spring one to shrink until the bottom of the limit plate is against the rotating roller. At this time, under the action of the rebound force of the spring one, the spring one will squeeze the limit block until one end of the limit block is inserted into the corresponding limit hole one. At this time, the limit block can limit the limit plate, and the two limit plates can limit the rotating roller, ensuring that it is convenient for personnel to replace the rotating roller and the rubber roller body.

[0016] In the above technical solution, further, one end of the limit block is plugged into and matched with the limit hole 1, and the movable plate 1 is slidably connected with the sliding groove.

[0017] In the technical solution, it is ensured that one end of the limit block can be inserted into the limit hole 1, so that the movable plate 1 can slide normally in the sliding groove.

[0018] In the above technical solution, further, one end of the limit block is in an inclined structure, and the limit block and the movable plate are an integrally formed structure.

[0019] In the technical solution, it is ensured that the rotation of the limiting plate can squeeze one end of the limiting block, so that the limiting block moves, thereby ensuring the structural stability of the limiting block and the movable plate.

[0020] In the above technical solution, further, the fixing assembly includes:

[0021] A slide groove is provided in the printer body and on one side of the paddle, a limiting hole 2 is provided on one side of the insert strip, a spring block is slidably installed in the slide groove, one end of the spring block passes through one side of the slide groove and extends into the limiting hole 2, a movable plate 2 is fixedly installed on one side of the spring block, and one side of the movable plate 2 passes through the slide groove and extends to the outside.

[0022] When the cleaning block is used for a long time and the cleaning effect of the cleaning block becomes worse, the personnel can move the movable plate 2, and the movable plate 2 will drive the spring block to move, so that the spring block moves in the slide groove and squeezes the spring 2 to shrink, until one end of the spring block moves out of the limiting hole 2. At this time, the spring block can release the fixing of the plug-in strip, and then the personnel can pull the plug-in strip out of the plug-in slot by the paddle. At this time, the personnel can replace the cleaning block on the plug-in strip, and then insert the replaced plug-in strip into the plug-in slot. At this time, the plug-in strip will squeeze one end of the spring block, so that the spring block moves and squeezes the spring 2 to shrink. When the plug-in strip is fully inserted into the plug-in slot, under the action of the rebound force of the spring 2, the spring 2 will squeeze the spring block to move until one end of the spring block is inserted into the limiting hole 2. At this time, the spring block can fix the plug-in strip, ensuring that it is convenient for personnel to replace the cleaning block and ensuring that the cleaning block can maintain a good cleaning effect.

[0086] When the rubber roller body 3 is damaged after long-term use, the personnel can respectively move the two moving plates 13. The movement of the moving plate 13 will drive the limit block 11 to move. The limit block 11 moves in the sliding groove 10 to squeeze the spring 12 to shrink until one end of the limit block 11 moves out of the limit hole 14. At this time, the limit block 11 can release the limit on the limit plate 9, and then the limit plate 9 is rotated again until the two limit plates 9 rotate 180°. At this time, the two limit plates 9 can release the limit on the rotating roller 8, and then the personnel can take out the rotating roller 8 and the rubber roller body 3 and replace them. After the replacement is completed, the two limit plates 9 are rotated again. The rotation of the limit plate 9 will squeeze one end of the limit block 11, so that the limit block 11 moves in the sliding groove 10 and squeezes the spring 12 to shrink until the bottom of the limit plate 9 is against the rotating roller 8. At this time, under the action of the rebound force of the spring 12, the spring 12 will squeeze the limit block 11 until one end of the limit block 11 is inserted into the corresponding limit hole 14. At this time, the limit block 11 can limit the limit plate 9, and the two limit plates 9 can limit the rotating roller 8, ensuring that it is convenient for personnel to replace the rotating roller 8 and the rubber roller body 3.
