Description
Technical Field
[0001] This utility model relates to the field of paper alignment technology, specifically a paper alignment structure for heat transfer printing. Background Technology
[0002] Heat transfer technology is widely used in printing, packaging, textiles, and other fields. Especially in large-scale production, the stability of paper transport has a crucial impact on product quality. During heat transfer, paper typically needs to be continuously transported via guide rollers, conveyor belts, and other equipment. However, due to errors in the mechanical equipment and the physical properties of the paper itself (such as deformation and uneven friction), the paper is prone to shifting or scattering during transport. These problems not only lead to paper waste but can also affect print quality and even damage printing equipment. Therefore, effectively preventing paper shifting, scattering, or wrinkling during transport and ensuring the stability and accuracy of paper during heat transfer has become a pressing technical challenge for the industry.
[0003] In existing technologies, some paper deviation correction devices are used to solve the problem of paper misalignment. However, these devices are often complex in structure, inconvenient to adjust, or unsuitable for different paper widths, and cannot effectively achieve precise adjustment. Furthermore, many existing roller pressing devices can only provide single pressure control and cannot automatically adjust according to actual needs, thus affecting paper tension and transmission stability. Therefore, how to design an efficient, precise, adaptable, and easy-to-operate thermal transfer paper deviation correction structure remains a technical challenge in the industry.

[0022] Please see Figure 1-3 A thermal transfer paper correction structure includes a mounting plate 1, a horizontal plate 2, a guide roller 3, and a correction and anti-scattering device 4. The guide roller 3 has connecting shafts fixedly connected to both ends, which are rotatably connected to the mounting plate 1. The horizontal plate 2 is fixedly connected to the upper end of the mounting plate 1, and a guide rail 5 is fixedly connected to the lower end of the horizontal plate 2. The correction and anti-scattering device 4 is slidably connected to the lower end of the guide rail 5. In this invention, the mounting plate 1 serves as the supporting foundation for the entire mechanism, the horizontal plate 2 provides support for the guide rail 5, and the guide rail 5 guides the relative movement of the correction and anti-scattering device 4. This structure is suitable for paper of different widths, correcting the paper transfer and preventing the paper from shifting or scattering.

[0023] In one embodiment of this utility model, the deviation correction and anti-scattering device 4 includes a movable frame 101, sliding guide blocks 102, sliding guide rings 103, drive blocks 104, bidirectional lead screws 105, limiting discs 106, and a roller pressing device.

Each drive block 104 has a threaded hole through it, and a bidirectional lead screw 105 is threaded into the threaded hole. The bidirectional lead screw 105 is rotatably connected between two sets of mounting plates 1. One end of the bidirectional lead screw 105 passes through the mounting plate 1 and is fixedly connected to a handwheel 107. The drive blocks 104 are fixedly connected to the upper end of the movable frame 101. Several sliding guide blocks 102 are fixedly connected to the lower end of the movable frame 101. The sliding guide blocks 102 are slidably connected to the sliding guide rings 103. Limiting discs 106 are fixedly connected to opposite sides of the sliding guide rings 103. Both the limiting discs 106 and the sliding guide rings 103... The guide roller 3 is slidably connected to the movable frame 101. Roller pressing devices are fixedly connected to the opposite sides of the movable frame 101. The lower ends of the roller pressing devices are rolled to the guide roller 3. In this embodiment, turning the handwheel 107 can drive the bidirectional lead screw 105 to rotate. The bidirectional lead screw 105 drives the drive block 104 to move towards or away from each other. The drive block 104 drives the sliding guide block 102 to move relative to each other through the movable frame 101. The sliding guide block 102 drives the sliding guide ring 103 to move along the guide roller 3. The sliding guide ring 103 drives the limiting plate 106 on one side to move. The limiting plate 106 can accurately control the position of the paper to avoid deviation during paper transmission. In addition, the roller pressing device can provide appropriate pressure to the paper to ensure good contact between the paper and the guide roller 3, avoid the paper being too loose or too tight during transmission, maintain appropriate tension, and prevent the paper from spreading or tangling.
[0024] In one embodiment of this utility model, the roller pressing device includes a support plate 201, telescopic rods 202, guide rods 203, a helical spring 204, a roller pressing block 205, guide rollers 206, and a shrinking assembly. A plurality of telescopic rods 202 are fixedly connected to the lower end of the support plate 201. The lower ends of the telescopic rods 202 are fixedly connected to the roller pressing block 205. A roller groove is formed at the lower end of the roller pressing block 205, and two sets of guide rollers 206 are rotatably connected within the roller groove. The guide rollers 206 and the guide rollers 203 are in rolling contact with each other. The upper part of the roller pressing block 205... A guide rod 203 is fixedly connected to the middle of the end. A guide hole is provided on the support plate 201 opposite to the guide rod 203. The guide rod 203 is slidably connected within the guide hole. After sliding out of the guide hole, the guide rod 203 connects to the shrinking assembly. The shrinking assembly is fixedly connected to the upper end of the support plate 201. A helical spring 204 is slidably connected to the guide rod 203 between the support plate 201 and the roller block 205. One end of the helical spring 204 abuts against the roller block 205, and the other end abuts against the support plate 201. In this embodiment, the support plate 201 is the supporting component of the entire roller pressing device. The telescopic rod 202 is used to connect the support plate 201 and the roller pressing block 205, and allows the roller pressing block 205 to move up and down. A guide rod 203 is fixedly connected to the middle of the upper end of the roller pressing block 205. The guide rod 203 is slidably connected to the support plate 201 through a guide hole, and is used to guide the roller pressing block to move up and down, ensuring that the roller pressing block 205 remains stable during the up and down movement. A helical spring 204 is slidably sleeved on the guide rod 203. The spring of the helical spring 204 is elastic. The force acts on the roller block 205, causing the guide roller 206 at the lower end of the roller block 205 to roll relative to the guide roller 3. The pressure is effectively transmitted to the paper, ensuring the stability and accuracy of the paper during the transmission process, ensuring that the paper does not deviate from the transmission path, and preventing it from spreading out. The shrinking component is connected to the guide rod 203, which can drive the roller block 205 to move upward through the guide rod 203, so that the guide roller 206 and the guide roller 3 can separate from each other, thereby facilitating the relative sliding of the sliding guide ring 103 and the limiting plate 106 along the guide roller 3.
[0025] In one embodiment of this utility model, a reinforcing rib 207 is fixedly connected between the support plate 201 and the movable frame 101 to improve the connection stability between the support plate 201 and the movable frame 101.
[0026] In one embodiment of this utility model, the shrinking assembly includes a piston cylinder 301, a piston block 302, a vacuum pump 303, a connecting pipe 304, and a solenoid valve 305. The piston cylinder 301 and the vacuum pump 303 are both fixedly connected to the upper end of the support plate 201. The piston block 302 is slidably connected inside the piston cylinder 301. The lower end of the piston block 302 is fixedly connected to the guide rod 203. A connecting pipe 304 is fixedly connected to one side of the upper end of the piston cylinder 301, and the other end of the connecting pipe 304 is connected to the vacuum pump 303. A vent pipe is fixedly connected to the other side of the upper end of the piston cylinder 301, and a solenoid valve 305 is fixedly connected to the vent pipe. In this embodiment, when it is necessary to connect the guide roller 206 and the guide roller 305... When the paper is separated, the solenoid valve 305 is closed and the vacuum pump 303 is started. The vacuum pump 303 extracts the air from the piston cylinder 301 through the connecting pipe 304, creating a negative pressure inside the piston cylinder 301. The negative pressure causes the piston block 302 to slide upward, thereby driving the guide rod 203 and the roller pressing block 205 to move upward, thus separating the guide roller 206 from the guide roller 3. When it is necessary to press the paper through the guide roller 206, the vacuum pump 303 is closed and the solenoid valve 305 is opened. At this time, external air enters the piston cylinder 301 through the vent pipe. Under the elastic force of the helical spring 204, the roller pressing block 205 moves downward, thereby causing the guide roller 206 to press downward onto the paper.
