Description

Technical Field

[0001] The utility model relates to the technical field of printers, and more specifically to a thermal transfer printer. Background Art

[0002] Printers can be seen everywhere in life, but due to the printing needs and various uses, the classification of printers can be said to be very different. Generally speaking, printers can be divided into dot matrix printers, inkjet printers, laser printers, thermal printers, thermal transfer printers, etc. These printers have different printing methods and materials according to different needs. There are many labels that must be able to withstand the test of time and not deform for a long time. The text must be stored for a long time, cannot fade, cannot be worn due to contact with solvents, cannot be deformed and discolored due to high temperatures, etc. Therefore, it is necessary to use a special material printing medium and printing material to ensure these characteristics. General inkjet printing technology cannot achieve this, nor can laser printing, and the effect of needle punching cannot meet the requirements of the original design, so thermal transfer technology has emerged.

[0003] In existing thermal transfer printers, the printing paper roll assembly is arranged in the flip cover, which makes the flip cover too heavy and easy to fall off and press the hand during use; in addition, since there are many exposed wires in the flip cover, it is not beautiful and easy to damage the wires.

[0004] In view of the above problems, regarding the technical problem that the existing printer has a heavy flip cover that is easy to overwhelm the hand, after a lot of searches, a thermal transfer printer with patent number 202221868083.2 was found, which belongs to the field of printer technology, including a base and a flip cover, one end of the flip cover is rotatably matched on the base, a buffer block matching the flip cover is provided on the base, and a closed wire groove is connected between the base and the flip cover, but the technical solution provided by the patent has the following problems:

[0005] When the paper roll inside the printer is used up, it needs to be replaced. Most printers do not have a limiting structure inside, which causes the printer to shake inside when using the paper roll, resulting in unstable printing, which in turn affects the quality of the printer's printing. At the same time, the printer can only use one specification of paper roll. When it is necessary to print paper of different specifications, the printer can only be replaced, which makes the printer inconvenient to use.

[0006] The utility model can make the printer more convenient to use. Utility Model Content

[0007] The utility model aims to solve the technical problems raised by the above-mentioned background technology and provides a thermal transfer printer.

[0008] To achieve the above object, the utility model provides the following technical solution: a thermal transfer printer, comprising: a body, a cover hinged on the upper end of the body, a roller arranged inside the body, and two baffles nested on the outer surface of the roller.

[0009] A further preferred solution is that a slot is provided inside the body, and both ends of the roller can be embedded in the slot, and the roller and the slot are movably connected.

[0010] A further preferred solution is that a positioning rod is embedded in the upper end of the body, and a positioning plate is nested on the outer surface of the positioning rod, and the positioning plate and the positioning rod are movably connected.

[0011] A further preferred solution is that a groove is provided on the inner side of the cover, and one end of the positioning plate can be embedded in the groove.

[0012] A further preferred solution is that a slide groove is provided on the surface of the roller, and a scale is provided on one side of the slide groove.

[0013] A further preferred solution is that limiting grooves are provided on the inner sides of the two baffles, and springs are installed inside the limiting grooves, and limiting blocks are fixedly installed at one end of the springs, and one end of the limiting blocks are embedded in the limiting grooves.

[0014] A further preferred solution is that one end of the limit block can be embedded in the slide groove, and the slide groove and the limit block are movably connected.

[0015] Beneficial effects:

[0016] 1. By setting a baffle, the baffle is used to limit the printing paper roll. When the two baffles are on the outer surface of the roller, the spring and the limit block are embedded in the inner part of the slide groove for limiting, so as to prevent the two baffles from falling off the surface of the roller, so that the device is more stable when being welded. When the baffle needs to adjust the position, the spring and the limit block move synchronously while the baffle moves. When the position of the baffle is determined, the baffle is directly rotated, and the spring and the limit block are forced to be embedded in the limit groove. At the same time, the limit block is in contact with the surface of the roller by the rebound force of the spring, so as to fix the position of the baffle, prevent the printing paper roll from shaking left and right during use, and affect the quality of the printing paper, so that the baffle is more flexible and convenient when in use, and effectively improves the stability of the device;

[0017] 2. By providing a positioning plate, when the cover is opened, the positioning plate is limited by the positioning rod, so that the positioning plate can rotate in place. While rotating, one end of the positioning plate is embedded in the groove to support the cover from the bottom to prevent the cover from loosening when opened, affecting the user's use. When the printing paper is replaced, the positioning plate returns to its original position, thereby resetting the cover, making the device more stable when in use;

[0018] 3. In summary, this type of thermal transfer printer, by providing structures such as a positioning plate and a baffle, makes the machine body more convenient and stable when replacing the printing paper roll. The positioning plate is embedded in the inside of the groove to support the machine cover from the bottom to prevent the machine cover from loosening when it is opened. The printing paper roll is limited by the roller, and the baffle is used to limit the two sides of the printing paper roll, which effectively prevents the printing paper roll from shaking on the surface of the roller during use, thereby reducing the probability of paper jam in the machine body and effectively improving the stability of the device.

[0025] The following will be combined with the attached embodiment of the utility model Figure 1-Figure 5 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0026] See also Figure 1-5 In an embodiment of the utility model, a thermal transfer printer comprises: a body 1, a cover 2 is hingedly connected to the upper end of the body 1, a roller 3 is arranged inside the body 1, and two baffles 4 are nested on the outer surface of the roller 3. When using the device, the printing paper roll is sleeved on the surface of the roller 3, and then the two baffles 4 are used to limit the two sides of the printing paper roll to prevent the printing paper roll from shifting during use, and then the cover 2 is used to block the space above the roller 3, which effectively reduces the influence of dust on printing and the influence on the stability of the use of the body 1. At the same time, the position of the printing paper roll can be adjusted by using the two baffles 4, and paper rolls of different sizes can be limited, making the device more flexible when used.

[0027] In the embodiment of the utility model, a slot 101 is opened on the inner side of the body 1, and the two ends of the roller 3 can be embedded in the slot 101, and the roller 3 and the slot 101 are movably connected. The slot 101 is used to limit the roller 3, which does not affect the rotation of the roller 3 and prevents the roller 3 from falling off, making the roller 3 more stable when in use.

[0028] In the embodiment of the utility model, a positioning rod 102 is embedded in the upper end of the body 1, and a positioning plate 103 is nested on the outer surface of the positioning rod 102, and the positioning plate 103 and the positioning rod 102 are movably connected. A groove 201 is provided on the inner side of the cover 2, and one end of the positioning plate 103 can be embedded in the groove 201. The cover 2 is not supported when it is opened and is easy to close again, thereby affecting the use of the body 1 and the user's experience. Therefore, the positioning plate 103 is provided to further support the cover 2. When the cover 2 is opened, the positioning plate 103 is rotated so that the positioning plate 103 is limited by the positioning rod 102, and one end of the positioning plate 103 is rotated into the inside of the groove 201, thereby supporting the cover 2 to prevent the cover 2 from closing again when it is opened, so that the printer is more stable when in use.

[0029] In the embodiment of the utility model, a slide groove 301 is provided on the surface of the roller 3, and a scale is provided on one side of the slide groove 301. When printing papers of different specifications are needed, the position of the printing paper roll on the surface of the roller 3 can be adjusted according to the scale, so that the printing paper roll can be limited at a position centered on the surface of the roller 3, reducing the impact of the shaking of the roller 3 on the printing paper roll, and effectively preventing the printing paper roll from causing paper jam in the machine body 1 when shaking, so that the printer is more stable when in use.

[0030] In the embodiment of the utility model, the inner sides of the two baffles 4 are provided with a limiting groove 401, and a spring 402 is installed inside the limiting groove 401, and a limiting block 403 is fixedly installed at one end of the spring 402, and one end of the limiting block 403 is embedded in the limiting groove 401, and one end of the limiting block 403 can be embedded in the slide groove 301, and the slide groove 301 and the limiting block 403 are movably connected. When the printing paper roll needs to be replaced, the printing paper roll is nested on the surface of the roller 3, and then fine-tuned with reference to the scale teeth, and finally the baffles 4 are used to limit the two sides of the printing paper roll. While limiting, the paper roll can rotate and cannot be stuck. The two baffles 4 are on the outer surface of the roller 3. When the position of the baffle 4 needs to be adjusted, the spring 402 and the limit block 403 move synchronously with the baffle 4 while the baffle 4 moves. When the position of the baffle 4 is determined, the baffle 4 is directly rotated, and the spring 402 and the limit block 403 are forced to be embedded in the limit groove 401. At the same time, the limit block 403 is in contact with the surface of the roller 3 due to the rebound force of the spring 402, thereby fixing the position of the baffle 4, making the baffle 4 more flexible and convenient to use, effectively improving the stability of the device, and thus effectively improving the stability of the device.

[0031] Working principle: when the machine body 1 needs to replace the printing paper roll, open the machine cover 2, move the positioning plate 103, so that the positioning plate 103 is limited by the positioning rod 102, and one end of the positioning plate 103 is rotated into the inside of the groove 201, thereby supporting the machine cover 2 to prevent the machine cover 2 from closing again when it is opened, so that the printer is more stable when in use, and the printing paper roll is nested on the surface of the roller 3, and then fine-tuned with reference to the scale teeth, and finally the baffle 4 is used to limit the two sides of the printing paper roll. While limiting, the paper roll can rotate and cannot be stuck. When the position of the baffle 4 is determined, the baffle 4 is directly rotated, and the spring 402 and the limit block 403 are forced to be embedded in the limit groove 401. At the same time, the limit block 403 is in contact with the surface of the roller 3 by the rebound force of the spring 402, thereby fixing the position of the baffle 4, making the baffle 4 more flexible and convenient when in use, effectively improving the stability of the device, and thus effectively improving the stability of the device.
