[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-5 The roller for a heat transfer machine shown includes a rubber roller 1;

[0027] The roller 5 is arranged inside the rubber roller 1 and is used to support the rubber roller 1. The outer surface of the roller 5 is provided with a slide groove 6 around it, and the outer surface of the roller 5 is provided with a threaded hole 7 around it. The slide groove 6 is movably connected with a slider 8 inside. A mounting sleeve 9 is fixedly installed on one side of the slider 8. The outer periphery of the mounting sleeve 9 is provided with a threaded groove 10. The outer periphery of the mounting sleeve 9 is penetrated by a first bolt 11. The rubber roller 1 of appropriate size is sleeved on the roller 5, and then the sliders 8 inside the mounting sleeves 9 on both sides are sleeved in the slide groove 6 in the roller 5 for sliding connection. The limit blocks 12 on one side of the two groups of mounting sleeves 9 are connected with the limit grooves 4 on both sides of the rubber roller 1. Then, the first bolt 11 is penetrated through the mounting sleeve 9 and the roller 5 for fixing. In this way, the length of the rubber roller 1 can be adjusted according to actual conditions.

[0028] like Figure 1 and Figure 2 As shown, a wear-resistant layer 2 is arranged on the outside of the rubber roller 1, and a high-temperature resistant layer 3 is arranged on the inside of the rubber roller 1. The material of the wear-resistant layer 2 is polyurethane, and the material of the high-temperature resistant layer 3 is silicone rubber. The wear-resistant layer 2 arranged on the outside of the rubber roller 1 enhances the wear resistance of the entire rubber roller 1 and improves its service life. At the same time, the temperature of the thermal transfer machine will be very high during printing. The high-temperature resistant layer 3 is arranged to enhance the heat resistance of the rubber roller 1.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, limiting grooves 4 are provided on both side surfaces of the rubber roller 1, and limiting blocks 12 are fixedly installed on one side surface of the mounting sleeve 9. The limiting grooves 4 are used in conjunction with the limiting blocks 12. When the limiting blocks 12 and the limiting grooves 4 are passed between the mounting sleeve 9 and the rubber roller 1, the firmness of the rubber roller 1 on the rubber roller 1 can be improved.

[0030] like Figure 1 and Figure 3 As shown, the installation sleeve 9 is slidably connected to the roller 5 through the slider 8, and the slider 8 is set in a "T" shape. The sliding groove 6 opened on the outside of the roller 5 is slidably connected with the slider 8 in the installation sleeve 9, which improves the stability of the mobile installation of the installation sleeve 9.

[0031] like Figure 1 and Figure 3 As shown, the thread grooves 10 are distributed in a circular array on the outside of both sides of the roller 5. The thread grooves 10 are used in conjunction with the mounting sleeve 9. The multiple groups of thread grooves 10 on the roller 5 can adjust the moving and fixing range of the mounting sleeve 9 according to the corresponding size of the rubber roller 1.

[0032] like Figure 1 and Figure 5 As shown, flanges 13 are fixedly installed on both sides of the roller 5, a connecting piece 14 is arranged on one side of the flange 13, and a second bolt 15 penetrates the outside of the connecting piece 14. The arrangement of the flange 13 facilitates the assembly of the roller 5 and the connecting piece 14, and such an arrangement facilitates disassembly and assembly by the staff.

[0033] The working principle of the utility model is as follows: firstly, according to the printing range of the thermal transfer machine, a rubber roller 1 of a suitable length is sleeved on the outside of the roller 5, and then two sets of mounting sleeves 9 are sleeved on both ends of the roller 5 respectively, and the sliders 8 inside the mounting sleeves 9 on both sides are sleeved in the slide grooves 6 inside the roller 5 to slide, and during the sliding process, the limit blocks 12 on one side of the two sets of mounting sleeves 9 are docked with the limit grooves 4 on both sides of the rubber roller 1, and then the first bolt 11 is used to penetrate the threaded groove 10 outside the mounting sleeve 9 and threadedly connect with the roller 5, and the mounting sleeves 9 on the left and right sides are limited. Fix, when fixed, assemble the flange 13 and the connecting piece 14 on both sides of the roller 5, and fix them through the second bolt 15. At this time, the whole stick can be installed in the thermal transfer machine. When the stick is in the printing process, the wear-resistant layer 2 arranged on the outside of the rubber roller 1 enhances the wear resistance of the whole rubber roller 1 and improves the service life. At the same time, when the thermal transfer machine is printing, the temperature will be very high. By setting the high temperature resistant layer 3, the heat resistance of the rubber roller 1 is enhanced. In this way, the use process of the roller for the thermal transfer machine is completed.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
