Description

Technical Field

[0001] This utility model relates to the field of tensioning technology, and in particular to a transfer film tensioning component for a heat transfer machine. Background Technology

[0002] A heat transfer machine is a device that uses heat and pressure to transfer a pattern pre-printed on a special carrier, usually paper or film, to the surface of another material, such as fabric, plastic, metal, ceramic, wood, etc.

[0003] To prevent the transfer film from loosening during movement, a tensioning component is usually added to the transfer film to improve its performance during heat transfer. However, existing tensioning components cannot adjust the tension, making them unsuitable for adjusting the tension of transfer films made of different materials. Therefore, we propose a transfer film tensioning component for heat transfer machines to solve the above problems. Utility Model Content

The spring force coefficient of the support spring can be adjusted by adjusting the position of the adjustment plate, so that the tension of the second shaft can be adjusted according to the material of the transfer film.

[0006] Preferably, a support shaft is provided at the top of the support base plate, and the height of the support shaft is adapted to the height of the second shaft. The transfer film can be placed above the support shaft after passing around the second shaft, so that the support shaft supports the transfer film and prevents the transfer film from contacting the table surface of the support base plate.

[0007] Preferably, a limiting shaft is provided inside the sliding slot, and the sliding block, support spring and adjusting plate are all sleeved on the outside of the limiting shaft; This improves the stability of the second shaft's sliding motion, and also enhances the performance of the support spring and adjusting plate.

[0008] Preferably, a connecting plate is provided on the side of the adjusting plate, and the other end of the connecting plate extends into the interior of another set of support rods and is fixedly connected to the adjusting plate inside it; The two sets of adjusting plates can be moved synchronously by the moving connecting plate, which makes it easier to adjust the spring force coefficient of the supporting spring.

[0009] Preferably, a mounting plate is provided on the side of the support rod, and a threaded adjusting rod is inserted into the middle position of the mounting plate, the end of the threaded adjusting rod being movably connected to the connecting plate; The connecting plate can be moved by rotating the threaded adjusting rod, which in turn moves the adjusting plate. The self-locking mechanism of the threaded adjusting rod can be used to position the adjusting plate.

[0010] Preferably, movable blocks are sleeved on both outer sides of the second shaft, and the movable blocks can slide outside the second shaft; The movable block can slide on the second shaft, thereby limiting the two sides of the transfer film and preventing the transfer film from shifting.

[0011] Preferably, a connecting ring is provided at the end of the movable block, the cross-section of the movable block and the connecting ring is T-shaped, and a threaded fixing rod is inserted at the top of the connecting ring; The movable block can be moved and then fixed by rotating the threaded fixing rod, thus fixing the threaded fixing rod after it moves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model can move the connecting plate by rotating the threaded adjusting rod, thereby adjusting the elastic coefficient of the support spring by the connecting plate and the adjusting plate, so that the tension of the second shaft can be adjusted to adapt to the tension of transfer film of different materials, which is more convenient to use.

[0013] 2. This utility model allows the movable block to slide outside the second shaft, and then be pressed and fixed with the second shaft by rotating the threaded fixing rod, thereby completing the positioning of the movable block. This allows the movable block to move to both sides of the transfer film, completing the limitation of the transfer film and preventing the transfer film from shifting or deviating during movement.

A support shaft 7 is fixedly installed on the top of the support base plate 1. The height of the support shaft 7 is adapted to the second shaft 6.

[0018] For a detailed description of the second shaft 6 in this embodiment, please refer to [link / reference]. Figure 3 and Figure 4The second shaft 6 extends into the interior of the support rod 2, and sliding blocks 9 are fixedly installed at both ends of the second shaft 6. Sliding slots 10 are then formed on both the upper and lower sides of the interior of the support rod 2, and the sliding blocks 9 extend into the interior of the sliding slots 10. A limiting shaft 11 is fixedly installed inside the sliding slots 10, and the sliding blocks 9 are sleeved on the outside of the limiting shaft 11. A support spring 12 is then sleeved on the outside of the limiting shaft 11. An adjusting plate 13 is provided inside the support rod 2, allowing the two ends of the adjusting plate 13 to... The adjustment plate 13 extends into the interior of the two sets of sliding slots 10.
