Technical Field

[0001] This utility model relates to the field of hot press roller technology, and in particular to a pressure balance hinged bracket for hot press rollers. Background Technology

[0002] A hot press roller is a cylindrical device that transfers designs or materials onto a substrate through heating and pressure. It is widely used in printing, packaging, and material processing. It is mainly used to transfer patterns or materials to the surface of substrates such as textiles, paper, and plastics through a hot pressing process to achieve pattern curing or composite effects.

[0003] In related technologies, hot press rollers need to be mounted on equipment by brackets for processing. However, hot press rollers expand when heated and contract when cooled. If the brackets are rigidly fixed, the size of the rollers will be restricted, which may lead to bending, deformation of the rollers or damage to the brackets.

[0004] Therefore, this utility model proposes a pressure-balanced hinged bracket for hot-pressing rollers to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a pressure-balanced hinged bracket for hot press rollers to solve the problem that in the prior art, hot press rollers expand when heated and contract when cooled. If the bracket is rigidly fixed, the size change of the roller will be restricted, which may lead to bending, deformation of the roller or damage to the bracket.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a pressure balancing hinged bracket for a hot press roller, comprising a support frame, two connecting rods fixedly installed on the inner side wall of the support frame near the top, connecting plates sleeved on the surfaces of the two connecting rods near their front and rear ends and slidably connected thereto, a connecting block slidably connected at the bottom center of the connecting plate, a hinge rod rotatably connected to the bottom of the connecting block, a hinge seat rotatably connected to the side of the hinge rod away from the connecting block, a mounting seat provided at the bottom of the hinge seat, a connecting block slidably connected to the inner side of the mounting seat, a hot press roller body rotatably connected between the two connecting blocks, a first spring provided inside the mounting seat and at the top of the connecting block, an adjustment component provided inside the support frame for adjusting the movement of the connecting plate, and a balancing component provided inside the connecting plate for balancing the pressure of the hot press roller body.

[0007] A further improvement is that mounting blocks are fixedly installed on the left and right sides of the support frame near the bottom, and mounting holes are provided at the center of the inner side of the mounting blocks.

[0008] A further improvement is that: a mounting bolt is provided through the inner side of the hinge seat near the front and rear sides, and a threaded hole adapted to the mounting bolt is opened on the top of the mounting seat.

[0009] A further improvement is that the adjustment assembly includes a threaded rod, the front and rear ends of which are rotatably connected to the inner sidewall of the support frame, an adjustment block is threaded on the surface of the threaded rod, the bottom of the adjustment block is fixedly connected to the top of the connecting plate, and knobs for driving the adjacent threaded rods to rotate are rotatably connected to the front and rear sides of the support frame.

[0010] A further improvement is that an adjustment groove is provided on the inner side of the support frame, allowing the adjustment block to slide left and right.

Detailed Implementation

[0021] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figure 1-5 As shown, this embodiment proposes a solution: a pressure balancing hinged bracket for a hot press roller, including a support frame 1. Two connecting rods 2 are fixedly installed on the inner side wall of the support frame 1 near the top. Connecting plates 3 are sleeved on the surfaces of the two connecting rods 2 near their front and rear ends and are slidably connected to them. A connecting block 4 is slidably connected to the bottom center of the connecting plate 3. A hinge rod 5 is rotatably connected to the bottom of the connecting block 4. A hinge seat 6 is rotatably connected to the side of the hinge rod 5 away from the connecting block 4. A mounting seat 7 is provided at the bottom of the hinge seat 6. A connecting block 8 is slidably connected to the inner side of the mounting seat 7. A hot press roller body 9 is rotatably connected between the two connecting blocks 8. A first spring 10 is provided on the inner side of the mounting seat 7 and at the top of the connecting block 8. An adjustment component is provided on the inner side of the support frame 1 for adjusting the movement of the connecting plate 3. A balancing component is provided on the inner side of the connecting plate 3 for balancing the pressure of the hot press roller body 9.

[0023] In this embodiment, the two ends of the hinge rod 5 are rotatably connected to the connecting block 4 and the hinge seat 6, respectively. The hinge seat 6 is fixed to the mounting seat 7 by the mounting bolt 12. When the hot press roller body 9 expands and contracts due to heat, its dimensional change is transmitted to the mounting seat 7 through the connecting block 8, which in turn drives the hinge seat 6. The hinge rod 5 adapts to this displacement change by rotating, avoiding rigid constraints. By adjusting the setting of the component, the position of the hot press roller body 9 can be actively adjusted to adapt to the positional change caused by its thermal expansion and contraction, ensuring that the hot press roller body 9 is in a suitable working position during processing, avoiding the impact of positional deviation on processing accuracy, and enhancing the adaptability of the support. The extension and retraction of the first spring 10 can effectively buffer the impact force generated by the thermal expansion and contraction of the hot press roller body 9. The sliding cooperation of the connecting block 8 provides space for the dimensional change of the roller body, avoiding rigid compression of the roller body, preventing the roller body from bending and deforming, and reducing damage to the mounting seat 7. With the setting of the balancing component, it can absorb the stress generated by the thermal expansion and contraction of the hot press roller body 9, further balancing the pressure.

[0024] Mounting blocks 11 are fixedly installed on the left and right sides near the bottom. Mounting holes are opened in the center of the inner side of the mounting blocks 11. The support frame 1 is fixed to the equipment through the mounting blocks 11 on the left and right sides at the bottom and the mounting holes on the inner side, providing basic support for the entire bracket.

[0025] Mounting bolts 12 are installed through the inner side of the hinge seat 6 near the front and rear sides. The top of the mounting seat 7 has threaded holes that match the mounting bolts 12. The mounting bolts 12 and the threaded holes facilitate the installation and disassembly of the hot press roller body 9, thereby enabling maintenance and increasing its service life.

[0026] The adjustment assembly includes a threaded rod 13, with its front and rear ends rotatably connected to the inner wall of the support frame 1. An adjustment block 14 is threaded onto the surface of the threaded rod 13, and the bottom of the adjustment block 14 is fixedly connected to the top of the connecting plate 3. The support frame 1 has knobs 15 rotatably connected to its front and rear sides to drive the adjacent threaded rods 13 to rotate. Rotating the knobs 15 drives the threaded rods 13 to rotate, causing the threaded adjustment blocks 14 to slide left and right along the adjustment groove 16, thereby causing the connecting plate 3 to slide on the connecting rod 2. When the hot press roller body 9 shifts position due to thermal expansion and contraction, the position of the connecting plate 3 can be adjusted through the adjustment assembly, thereby indirectly adjusting the position of the hot press roller body 9.

[0027] The inner side of the support frame 1 is provided with an adjustment groove 16 for the adjustment block 14 to slide left and right, thereby increasing the stability of the movement of the adjustment block 14.

[0028] The balancing assembly includes two movable rods 17. The inner wall of the connecting block 4 has sliding holes that slide with the surface of the movable rods 17. The inner wall of the connecting plate 3 and the outer edge of the movable rods 17 are provided with a second spring 18 to drive the connecting block 4 to slide. The elasticity of the second spring 18 can absorb the stress generated by the thermal expansion and contraction of the hot press roller body 9, further balancing the pressure. The movable rods 17 ensure the stability of the sliding of the connecting block 4, thereby protecting the roller body and the support and extending the service life of the device.

[0029] The above embodiment discloses a pressure-balanced hinged bracket for a hot press roller. The support frame 1 is fixed to the equipment via mounting blocks 11 on the bottom of both sides and mounting holes on the inner side, providing basic support for the entire bracket. The hinge rod 5 is rotatably connected at both ends to the connecting block 4 and the hinge seat 6, respectively. The hinge seat 6 is fixed to the mounting base 7 via mounting bolts 12. When the hot press roller body 9 expands and contracts due to heat, its dimensional change is transmitted to the mounting base 7 through the connecting block 8, thereby driving the hinge seat 6. The hinge rod 5 adapts to this displacement change by rotation, avoiding rigid constraints. The extension and retraction of the first spring 10 effectively buffers the impact force generated by the thermal expansion and contraction of the hot press roller body 9. The sliding fit of the connecting block 8 provides space for the dimensional changes of the roller body, avoiding... The roller body is not subjected to rigid compression, preventing it from bending or deforming, and reducing damage to the mounting base 7. At the same time, the elasticity of the second spring 18 can absorb the stress generated by the thermal expansion and contraction of the hot press roller body 9, further balancing the pressure. Rotating the knob 15 drives the threaded rod 13 to rotate, causing the threaded adjustment block 14 to slide left and right along the adjustment groove 16, thereby driving the connecting plate 3 to slide on the connecting rod 2. When the hot press roller body 9 shifts position due to thermal expansion and contraction, the position of the hot press roller body 9 can be actively adjusted to adapt to the positional changes caused by thermal expansion and contraction, ensuring that the hot press roller body 9 is in a suitable working position during processing, avoiding the impact of positional shift on processing accuracy, and enhancing the adaptability of the support.
