Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer machines, in particular to a transfer film tensioning component for a heat transfer machine. Background Art

[0002] A heat transfer machine is a device used to transfer patterns, text or images from transfer materials (such as heat transfer paper or heat transfer film) to other materials (such as fabrics, ceramics, metals, plastics, etc.). It is widely used in clothing printing, advertising production, gift customization and other fields.

[0003] When using a thermal transfer machine, a tensioning assembly is required to tension the transfer film so that the transfer film can fit tightly against the surface of the material to be transferred. However, the length of the tensioning roller of the existing tensioning assembly is fixed. When tensioning a narrow transfer film, the transfer film is likely to move on the surface of the tensioning roller, causing the transfer film to deviate, thereby affecting the quality of the transfer. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a transfer film tensioning assembly for a thermal transfer machine, which has the advantage of preventing the transfer film from shifting. It solves the problem that the length of the tensioning roller of the existing tensioning assembly is fixed, and the transfer film is easily moved on the surface of the tensioning roller when tensioning a transfer film with a narrow width, causing the transfer film to shift and affecting the quality of the transfer.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a transfer film tensioning assembly for a thermal transfer machine, comprising a base plate, a first U-shaped frame fixedly mounted on the upper surface of the base plate, two second U-shaped frames, a top roller rotatably mounted on the inner side of the first U-shaped frame, and a pressure roller rotatably mounted on the inner side of the second U-shaped frame, wherein the first U-shaped frame and the second U-shaped frame are provided with a limit adjustment mechanism;

[0006] The limit adjustment mechanism includes a sliding rod fixedly installed on the inner side of the first U-shaped frame and the second U-shaped frame, two movable plates slidably installed on the surface of the sliding rod, a retaining ring rotatably installed on the surface of the movable plate, a groove opened on the inner side surface of the first U-shaped frame and the second U-shaped frame, a first threaded rod rotatably installed in the groove, a second threaded rod fixedly installed at one end of the first threaded rod, and a connecting block threadedly connected to the surfaces of the first threaded rod and the second threaded rod.

[0007] Furthermore, a first circular hole and a second circular hole are opened on the surface of the movable plate, the retaining ring is rotatably installed inside the first circular hole, and the sliding rod is located inside the second circular hole.

[0008] Furthermore, the first U-shaped frame is located between the two second U-shaped frames, and the height of the top roller is higher than that of the two pressure rollers.

[0009] Furthermore, the retaining ring on the first U-shaped frame is sleeved on the surface of the top roller, and the retaining ring on the second U-shaped frame is sleeved on the surface of the pressure roller.

[0010] Furthermore, a connecting column is fixedly installed at the connection between the first threaded rod and the second threaded rod, and a threaded hole is opened on the surface of the connecting block.

[0011] Furthermore, a connecting rod penetrating the outer surfaces of the first U-shaped frame and the second U-shaped frame is fixedly mounted on one end of the second threaded rod, and a rotating handle is fixedly mounted on one end of the connecting rod.

[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0013] The transfer film tensioning assembly for the thermal transfer machine is provided with adjustable and movable retaining rings on the top roller and the pressure roller. The two retaining rings can be used to limit the transfer film on the top roller and the pressure roller, so that the transfer film will not deviate during the transfer process, which is beneficial to improving the transfer effect. It solves the problem of the existing tensioning assembly whose tensioning roller has a fixed length. When a transfer film with a narrow width is tensioned, the transfer film is easily moved on the surface of the tensioning roller, causing the transfer film to deviate, thereby affecting the quality of the transfer.
