The utility model can adjust the lower half or the upper half of the printing belt alternately corresponding to the thermal print head by adjusting the screw, so that the thermal print head only performs thermal transfer on the solid ink in the upper half area of ​​the printing belt, or only performs thermal transfer on the solid ink in the lower half area of ​​the printing belt.

[0004] During the use of the printing belt assembly of the existing thermal transfer printer, due to the lack of a sufficiently stable device, the printer will shake during operation, and the printed fonts or patterns are not clear enough, affecting the use. Since there is no cutting device, many printing scenarios require the printed materials to be cut, such as label printing. In this case, manual operation is often required, which is time-consuming and labor-intensive, and the cutting may not be standard.

[0005] Therefore, in view of the above problems, a printing ribbon assembly for a thermal transfer printer is proposed. Utility Model Content

[0006] In order to solve the problems raised in the above background technology, the utility model provides a printing belt assembly for a thermal transfer printer, which has the advantages of automatically cutting the printed product and enhancing the stability of the printing assembly.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a printing tape assembly for a thermal transfer printer, comprising a component box body, one side of the component box body is fixedly connected to a photosensor, one side of the component box body is fixedly connected to a fixed block one, the interior of the fixed block one is slidably connected to a cutting knife, the top of the cutting knife is fixedly provided with meshing teeth, one side of the fixed block one is fixedly connected to a motor, one side of the motor is rotatably connected to a gear, and the gear and the meshing teeth are meshed with each other, the top of the component box body is attached to a box cover, and the interior of the component box body is rotatably provided with a rotating shaft.

[0008] Preferably, a fixing column 1 is fixedly connected to one side of the component box body, and the number of the fixing column 1 is set to two.

[0009] Preferably, one end of the fixing column 1 is fixedly connected to a fixing block 2, and a stud is spirally connected inside the fixing block 2.

[0010] Preferably, a disc is fixedly connected to the top of the stud, and a handle is rotatably connected to the top of the disc.

[0011] Preferably, the outer side of the bottom end of the stud is slidably connected to a component base, and the top end of the component base is fixedly connected to a thermal printer head.

[0012] Preferably, a printing carbon ribbon is attached to the outer side of the rotating shaft, and a second fixing column is attached to one side of the printing carbon ribbon.

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

[0014] 1. The utility model combines a photosensitive sensor, a cutting knife, a fixing block and a gear structure. When using a thermal transfer printer, the user first turns on the power supply to check whether the printing carbon ribbon is sufficient. After the inspection, the box cover is closed to perform thermal transfer printing. When the printed material passes through the photosensitive sensor, the sensor will detect the part of the thermal printing paper that does not contain carbon. At this time, the sensor transmits a signal to the motor, and the motor drives the gear to rotate. The gear meshes with the meshing teeth at the top of the cutting knife, and the cutting knife quickly moves toward the thermal printing paper to cut it off. This device can cut the printed material, eliminating the step of manual cutting, and increases the cutting accuracy and speeds up work efficiency.

[0015] 2. The utility model combines a fixed column 1, a fixed block 2, a stud and a handle structure. When using a thermal transfer printer, the user sometimes needs to print narrow text or patterns. If the width of the entire printing tape is used, it will cause a waste of resources. At this time, the handle can be rotated around the disc to rotate the stud. The fixed block 2 is provided with a thread. The rotation of the stud causes the fixed block 2 to move up or down, and the fixed block 2 drives the fixed column 1 to move up and down, thereby achieving the purpose of moving the component box up and down. In addition, since there are two fixed columns 1, the overall stability of the printing component is greatly improved, avoiding the influence of vibration generated during the operation of the printer on the printing result.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4As shown, the utility model provides a printing belt assembly for a thermal transfer printer, including an assembly box body 1, one side of the assembly box body 1 is fixedly connected to a photosensor 2, one side of the assembly box body 1 is fixedly connected to a fixed block 3, a cutting knife 4 is slidably connected inside the fixed block 3, the top of the cutting knife 4 is fixedly provided with a meshing tooth 6, one side of the fixed block 3 is fixedly connected to a motor 5, one side of the motor 5 is rotatably connected to a gear 7, and the gear 7 and the meshing tooth 6 are meshed with each other, a box cover 8 is attached to the top of the assembly box body 1, a rotating shaft 17 is rotatably provided inside the assembly box body 1, the gear 7 and the meshing tooth 6 are meshed with each other so that the cutting knife 4 can cut quickly, and the photosensor 2 transmits a cutting signal to the motor 5 when cutting is required, so that the cutting knife 4 can cut the printed result more accurately.

[0023] Specifically, one side of the component box body 1 is fixedly connected with a fixing column 9, and the number of the fixing columns 9 is set to two. The two fixing columns 9 greatly improve the overall stability of the printing component.

[0024] Furthermore, one end of the fixed column 9 is fixedly connected to a fixed block 10, and the internal spiral of the fixed block 10 is connected to a stud 11. The stud 11 can move the fixed block 10 upward or downward by rotating, so as to accurately control the relative position of the printing carbon ribbon 16 and the thermal printer head 14.

[0025] Furthermore, the top of the stud 11 is fixedly connected to a disc 12, and the top of the disc 12 is rotatably connected to a handle 13. The handle 13 increases the distance of the force arm at the edge of the disc 12, which can make the movement more precise.

[0026] It is worth noting that the outer side of the bottom end of the stud 11 is slidably connected to the component base 18, and the top end of the component base 18 is fixedly connected to the thermal printer head 14, which prints the printing material onto the printing paper.

[0027] It is worth noting that the outer side of the rotating shaft 17 is attached with a printing carbon ribbon 16 , and one side of the printing carbon ribbon 16 is attached with a second fixing column 15 , and the second fixing column 15 can reduce the occurrence of the phenomenon that the printing carbon ribbon 16 is messed up.

[0028] Among them, the photosensitive sensor 2, the printing ribbon 16, the thermal printer head 14 and the motor 5 are existing technologies and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0029] Working principle and process: When operating the thermal transfer printer, the user first needs to turn on the power and check whether the printing ribbon 16 is sufficient. After confirming that it is correct, close the box cover 8, and the rotating shaft 17 rotates to drive the printing ribbon 16 outside the fixed column 15 to start the thermal transfer process. The printed material will be detected when passing through the photosensitive sensor 2. The sensor can identify the non-carbon-containing part of the thermal printing paper and send a signal to the motor 5 accordingly. The motor 5 then drives the gear 7 to rotate and mesh with the meshing teeth 6 at the top of the cutter 4, so that the cutter 4 inside the fixed block 3 moves quickly and cuts off the thermal printing paper. This step not only eliminates the need for manual cutting, but also improves the cutting accuracy and work efficiency. In addition When it is necessary to print narrow text or patterns, in order to reduce resource waste, the user can adjust the relative position of the printing ribbon 16 and the thermal printer head 14 at the top of the component base 18. By rotating the handle 13 on the disc 12, the stud 11 will rotate accordingly. Since the fixed block 10 is provided with a matching thread inside, the rotation of the stud 11 causes the fixed block 10 to move up or down, thereby driving the fixed column 1 9 to move up and down. This design realizes the up and down movement of the component box 1. This device enhances the overall stability of the printing component, effectively avoids the potential impact of vibration on the printing result, realizes automatic cutting and greatly increases the stability of the device, ensuring the economy of the printing process and the high quality of the results.
