Technical Field

[0001] This utility model relates to the field of thermal printer technology, specifically to an auxiliary cooperation structure for thermal printers. Background Technology

[0002] Thermal printers, with their advantages of fast printing speed, low noise, compact structure, and convenient maintenance, have been widely used in many commercial and office scenarios such as cashier settlement, medical prescription printing, logistics waybill printing, and invoice issuance. Their core working principle is to heat thermal paper with a thermal head, causing a chemical reaction in the paper coating to produce text or patterns. After printing, the continuous thermal paper needs to be cut into individual documents for subsequent use or archiving.

[0003] The problem with existing technology is that the paper in existing thermal printers usually needs to be cut manually. However, manual operation is not only inefficient and prone to skewed or rough edges, but may also result in the wrong cut of valid printing content, ultimately leading to incomplete data and paper waste. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide an auxiliary structure for thermal printers, which has the advantages of automatically cutting paper and pressing down the cut paper to prevent it from falling. This solves the problem that in the use of existing thermal printers, the printing paper usually needs to be cut manually, which is not only inefficient and prone to skewed or rough edges, but may also result in the wrong cutting of valid printing content, ultimately leading to incomplete data and paper waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary cooperation structure for a thermal printer, comprising a main body and a paper outlet, wherein a cutting mechanism is provided on the top of the main body.

[0006] The cutting mechanism includes a housing, an abutment blade is fixedly connected to the inner cavity of the housing, and a cutting blade is provided on the front side;

[0007] The rear side of the housing is provided with a drive assembly that works with the cutting blade, while the top is provided with a pressing assembly that works with the drive assembly.

[0008] The housing is located behind the paper outlet and its bottom is fixedly connected to the main body of the equipment. The front side of the abutting blade passes through the housing and extends to the outside of the housing. The cutting blade is located in front of the paper outlet.

[0009] As a preferred embodiment of the present invention, the drive assembly includes a miniature electric cylinder, the rear side of which is fixedly connected to the housing, and a push plate is fixedly connected to the output shaft. Connecting rods are fixedly connected to the left and right sides of the push plate, and the side of the connecting rod closest to the cutting blade is fixedly connected to the cutting blade.

[0010] As a preferred embodiment of this invention, a T-shaped block is fixedly connected to the side of the connecting rod near the housing, and multiple toothed grooves are formed on the top surface.

[0011] As a preferred embodiment of this utility model, T-shaped grooves are provided on both the left and right sides of the housing, and the side of the T-shaped block away from the connecting rod is located in the inner cavity of the T-shaped groove and contacts the inner wall of the T-shaped groove.

[0012] In a preferred embodiment of this invention, the pressing assembly includes a pressure plate and a gear. Rotating rods are fixedly connected to the left and right sides of the bottom of the pressure plate, and the bottom of the rotating rods is fixedly connected to the gear.

[0013] In a preferred embodiment of this invention, the gear is rotatably connected to the housing on the side near the housing, while its bottom engages with the tooth groove, and a rubber pad is fixedly connected to the front side of the pressure plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model solves the problem that existing thermal printers usually require manual cutting of printing paper, which is not only inefficient and prone to skewing or rough edges, but may also accidentally cut out valid printing content, resulting in incomplete data and paper waste. The invention achieves the effect of automatically cutting the printing paper, ensuring a flat cut, and pressing down the cut paper to prevent it from falling.

[0016] 2. This utility model achieves smooth cutting of printing paper by setting a cutting blade and a driving assembly, ensuring cutting quality. The micro electric cylinder drives the push plate and connecting rod to move linearly, causing the cutting blade to engage with the abutting blade, avoiding skewing or miscutting of effective content, and ensuring the integrity of printed data. The T-block and T-slot slide together, limiting the connecting rod to move only in the horizontal direction without deviation or shaking, ensuring that the cutting blade is subjected to uniform force and the cutting edge is flat.

[0017] 3. This utility model achieves synchronous pressing and fixing of the paper after cutting by setting a pressing component, which prevents it from falling or shifting. When the connecting rod of the drive component drives the cutting blade to move, the tooth groove and gear mesh and drive the rotating rod to drive the pressure plate to flip down synchronously. The cutting and pressing actions are seamlessly connected and no additional drive source is required. The rubber pad at the bottom of the pressure plate flexibly adheres to the surface of the printing paper, which firmly fixes the cut paper and prevents it from falling. No additional manual pressing or fixing is required. Attached Figure Description

[0026] Example 1

[0027] Reference Figure 1-3 This is the first embodiment of the present invention, which provides an auxiliary structure for a thermal printer, including a main body 1 and a paper outlet 2. A cutting mechanism 3 is provided on the top of the main body 1.

[0028] The cutting mechanism 3 includes a housing 31, with an abutment blade 32 fixedly connected to the inner cavity of the housing 31, and a cutting blade 33 provided on the front side;

[0029] A drive assembly 34 for use with the cutting blade 33 is provided on the rear side of the housing 31, and a pressing assembly 35 for use with the drive assembly 34 is provided on the top.

[0030] The housing 31 is located behind the paper outlet 2 and its bottom is fixedly connected to the main body 1 of the equipment. The front side of the abutting blade 32 passes through the housing 31 and extends to the outside of the housing 31. The cutting blade 33 is located in front of the paper outlet 2.

[0031] Specifically, by setting up the cutting mechanism 3, the problem of manually cutting the printing paper in existing thermal printers is solved. Manual operation is not only inefficient and prone to skewed or rough edges, but may also accidentally cut valid printing content, resulting in incomplete data and paper waste. The solution achieves the effect of automatically cutting the printing paper, ensuring a flat cut, and pressing down the cut paper to prevent it from falling.

[0032] Furthermore, after printing is completed, the drive component 34 is activated, driving the cutting blade 33 to move towards the abutting blade 32. The two engage to achieve automatic paper cutting. At the same time, the drive component 34 drives the pressing component 35 to move synchronously through the transmission structure. At the moment the cutting is completed, the pressing component 35 presses down the cut paper to prevent it from falling. After the cutting and pressing actions are completed, the drive component 34 drives all components to reset, waiting for the next printing and cutting, without the need for manual operation.

[0033] Example 2

[0034] In the second embodiment of this utility model, the drive assembly 34 includes a miniature electric cylinder 341. The rear side of the miniature electric cylinder 341 is fixedly connected to the housing, and the output shaft is fixedly connected to a push plate 342. The left and right sides of the push plate 342 are fixedly connected to connecting rods 343, and the side of the connecting rod 343 near the cutting blade 33 is fixedly connected to the cutting blade 33.

[0035] A T-shaped block 4 is fixedly connected to the side of the connecting rod 343 near the housing 31, and multiple toothed grooves 5 are opened on the top surface.

[0036] T-shaped grooves 6 are provided on both the left and right sides of the housing 31. The side of the T-shaped block 4 away from the connecting rod 343 is located in the inner cavity of the T-shaped groove 6 and is in contact with the inner wall of the T-shaped groove 6.

[0037] Specifically, by setting the cutting blade 33 and the drive assembly 34, the printing paper is cut smoothly to ensure the cutting quality. The micro electric cylinder 341 drives the push plate 342 and the connecting rod 343 to move linearly, which causes the cutting blade 33 to engage with the abutting blade 32, avoiding skewing or miscutting of effective content and ensuring the integrity of the printed data. The T-block 4 and the T-slot 6 slide together to restrict the connecting rod 343 to move only in the horizontal direction without deviation or shaking, ensuring that the cutting blade 33 is subjected to uniform force and the cutting edge is flat.

[0038] Furthermore, when paper needs to be cut, the output shaft of the micro electric cylinder 341 is extended, pushing the push plate 342 to move backward. The push plate 342 drives the connecting rods 343 on both sides to move backward synchronously. The connecting rods 343 slide smoothly along the T-groove 6 through the T-block 4 to avoid deviation, and at the same time drive the cutting blade 33 to move towards the abutting blade 32.

[0039] When the cutting blade 33 and the abutting blade 32 are fully engaged, the paper is cut. After the cutting is completed, the output shaft of the micro electric cylinder 341 retracts, driving the push plate 342, the connecting rod 343 and the cutting blade 33 to reset, waiting for the next action; the toothed groove 5 moves synchronously with the connecting rod 343 to provide transmission power for the pressing assembly 35.

[0040] Example 3

[0041] In the second embodiment of this utility model, the pressing component 35 includes a pressure plate 351 and a gear 352. A rotating rod 353 is fixedly connected to the left and right sides of the bottom of the pressure plate 351, and the bottom of the rotating rod 353 is fixedly connected to the gear 352.

[0042] The gear 352 is rotatably connected to the housing 31 on the side near the housing 31, and its bottom meshes with the tooth groove 5. A rubber pad 7 is fixedly connected to the front side of the pressure plate 351.

[0043] Specifically, by setting up the pressing component 35, the paper is pressed down and fixed synchronously after cutting to prevent it from falling or shifting. When the connecting rod 343 of the drive component 34 drives the cutting blade 33 to move, the toothed groove 5 and the gear 352 mesh and drive the rotating rod 353 to drive the pressure plate 351 to flip down synchronously. The cutting and pressing actions are seamlessly connected without the need for an additional drive source. The rubber pad 7 at the bottom of the pressure plate 351 flexibly adheres to the surface of the printing paper, which firmly fixes the cut paper and prevents it from falling, without the need for manual additional pressing or fixing.

[0044] Furthermore, when the connecting rod 343 moves forward, the toothed groove 5 at the top meshes with the gear 352, causing the gear 352 to rotate around the housing 31. The gear 352 drives the pressure plate 351 to flip downward synchronously through the rotating rod 353. The rubber pad 7 on the front side of the pressure plate 351 gradually approaches and adheres to the surface of the printing paper. When the cutting blade 33 completes the cutting, the rubber pad 7 just presses the cut paper tightly. When the cutting is reset, the connecting rod 343 moves backward, the toothed groove 5 drives the gear 352 to rotate in the opposite direction, and the pressure plate 351 flips upward to reset, releasing the paper for easy access by the operator.

[0045] Working principle:

[0046] After the thermal printer finishes printing the specified content, the continuous thermal paper extends from the paper exit 2 to the preset length. When the paper needs to be cut, the micro electric cylinder 341 is activated, and the output shaft of the micro electric cylinder 341 of the drive assembly 34 extends, pushing the push plate 342 and the connecting rods 343 on both sides to move forward along the T-shaped groove 6. The connecting rods 343 drive the cutting blade 33 to move synchronously towards the abutting blade 32. The two gradually approach and bite together. Under the action of shearing force, the thermal paper is precisely cut with a smooth cut without burrs, avoiding the miscutting of effective printed content.

[0047] As the connecting rod 343 moves forward, the toothed groove 5 at the top continuously meshes with the gear 352 of the pressing assembly 35, causing the gear 352 to rotate. The gear 352 drives the pressure plate 351 to flip downward through the rotating rod 353. The rubber pad 7 on the front side of the pressure plate 351 moves synchronously with the pressure plate 351. At the moment when the cutting blade 33 completes the cutting, the rubber pad 7 flexibly adheres to and presses the cut paper to prevent the paper from falling or shifting due to its own weight or the push of subsequent paper.

[0048] After cutting and pressing, the output shaft of the miniature electric cylinder 341 retracts, driving the push plate 342, connecting rod 343 and cutting blade 33 to return to their original position along the T-groove 6. The tooth groove 5 moves in the opposite direction with the connecting rod 343, driving the gear 352 to rotate in the opposite direction. The pressure plate 351 flips upward to return to its original position, releasing the paper.

[0049] The operator can easily retrieve the fixed cutting document, and the device returns to its initial state, waiting for the next printing cutting instruction.

[0050] In summary, by setting the cutting mechanism 3, the printing paper can be automatically cut, ensuring a clean cut, and the cut paper can be held in place to prevent it from falling.
