Technical Field

[0001] The utility model relates to the technical field of winding rollers, in particular to a winding roller for thermal transfer film. Background Technique

[0002] Thermal transfer is a type of transfer printing. In essence, patterns or texts are pre-printed on a substrate film to form a thermal installation concealment. Then, through the action of heat and pressure, the graphics and texts on the printing layer are transferred onto the substrate.

[0003] After retrieval, the authorized Chinese patent publication number CN 218642016 U discloses a winding roller for PE film, including a base. A mounting frame is fixedly connected to the top of the base near the side wall for fixing the position of the winding mechanism. By arranging a tensioning mechanism before the winding roller in the utility model, the tension of the PE film can be adjusted according to its toughness, improving the winding quality, preventing folding, and simplifying the structure, making it more convenient to disassemble and maintain in the later stage and improving the maintenance efficiency.

[0004] There are still certain deficiencies in the winding roller in the above patent. During the thermal transfer printing process, a winding roller for thermal transfer film is needed for subsequent winding work. However, the size of the existing thermal transfer film winding roller is fixed. When winding films of different widths, not only is it necessary to search back and forth for a suitable winding roller, but also the disassembly and assembly of the winding roller are relatively troublesome, reducing the working efficiency during film winding.

[0027] Please refer to Figures 1-3

[0028] Embodiment 1: A winding roller for a thermal transfer film includes a middle winding component 1. A left winding component 2 is arranged on one side of the middle winding component 1, and a right winding component 3 is arranged on the other side of the middle winding component 1. Two connecting screws 4 penetrate through the middle winding component 1, the left winding component 2 and the right winding component 3, and fastening nuts 5 are sleeved at both ends of the connecting screws 4.

[0029] The middle winding component 1 includes a middle winding cylinder 101. One end of the middle winding cylinder 101 is provided with a first connection slot 102. A number of first limit slots 103 are evenly opened on the side of the first connection slot 102. Two first through holes 104 are symmetrically opened on the middle winding cylinder 101. The other end of the middle winding cylinder 101 is provided with a first connection block 105. A number of first limit plugs 106 are evenly arranged on the side of the first connection block 105.

[0030] The left winding component 2 includes a left winding cylinder 201 arranged on the left side of the middle winding cylinder 101. One end of the left winding cylinder 201 is provided with a left mounting post 202. The other end of the left winding cylinder 201 is provided with a second connection slot 203. A number of second limit slots 204 are evenly opened on the side of the second connection slot 203. Two second through holes 205 are symmetrically opened on the left winding cylinder 201.

[0031] The right winding component 3 includes a right winding cylinder 301 arranged on the side of the middle winding cylinder 101. One end of the right winding cylinder 301 is provided with a second connection block 302. A number of second limit plugs 303 are evenly arranged on the side of the second connection block 302. Two third through holes 304 are symmetrically opened on the right winding cylinder 301. The other end of the right winding cylinder 301 is provided with a right mounting post 305.

[0032] Embodiment 2: The difference between this embodiment and Embodiment 1 is that, among them, the connecting screw 4 sequentially passes through the third through hole 304, the first through hole 104, and the second through hole 205.

[0033] So that the middle winding cylinder 101, the left winding cylinder 201, and the right winding cylinder 301 are more firmly connected together by the connecting screw 4.

[0034] Embodiment 3: The difference between this embodiment and Embodiment 1 is that, among them, the first connection block 105, the second connection slot 203, the first connection slot 102, and the second connection block 302 have the same longitudinal section diameter.

[0035] So that the first connection block 105 is more appropriately inserted into the second connection slot 203, and the second connection block 302 is more appropriately inserted into the first connection slot 102.

[0036] Embodiment 4: The difference between this embodiment and Embodiment 1 is that, among them, the first limit plug 106, the second limit slot 204, the second limit plug 303, and the first through hole 104 have the same longitudinal section diameter.

[0037] So that the first limit plug 106 is more appropriately inserted into the second through hole 205, and the second limit plug 303 is more appropriately inserted into the first limit slot 103.

[0038] In this embodiment, since the size of the existing heat transfer printing film winding roller is fixed, when winding printing films of different widths, not only is it necessary to search back and forth for a suitable winding roller, but also the disassembly and assembly of the winding roller are relatively troublesome, reducing the working efficiency during the winding of the printing film.

[0039] In summary, during specific implementation, when the user needs to wind a relatively wide printing film, the user can combine the middle winding assembly 1, the left winding assembly 2, and the right winding assembly 3. By passing the connecting screw 4 through the first through hole 104 in the middle winding cylinder 101, the second through hole 205 in the left winding cylinder 201, and the third through hole 304 in the right winding cylinder 301, and inserting the first connecting block 105 at the end of the middle winding cylinder 101 into the second connecting slot 203, and inserting the second connecting block 302 at the end of the right winding cylinder 301 into the first connecting slot 102.

[0040] Furthermore, it can make the middle winding cylinder 101, the left winding cylinder 201, and the right winding cylinder 301 be closely connected to form a winding roller for heat transfer printing film. Then, by sleeving a fastening nut 5 on the end of the connecting screw 4, the middle winding cylinder 101, the left winding cylinder 201, and the right winding cylinder 301 are fixedly connected, and the length of the connecting screw 4 can be replaced and adjusted according to the combined length of the user.

[0041] When the user needs to wind a heat transfer printing film with a relatively narrow width, the user can remove the middle winding assembly 1 from the left winding assembly 2 and the right winding assembly 3, and directly insert the second connecting block 302 at the end of the right winding cylinder 301 into the second connecting slot 203 opened at the end of the left winding cylinder 201, and insert the second limit insertion block 303 into the second limit slot 204, so that the right winding cylinder 301 and the left winding cylinder 201 are preliminarily connected. Then, by passing the connecting screw 4 through the third through hole 304 and the second through hole 205, the right winding cylinder 301 and the left winding cylinder 201 are connected.

[0042] Furthermore, a winding roller with a relatively short length can be formed, which can wind printing films with a relatively narrow width, so that the winding length of the winding roller can be conveniently adjusted to adapt to printing film products of different widths, without the need to search for the winding roller back and forth and repeatedly disassemble and assemble, making it more convenient and fast to use, and greatly improving the working efficiency during the winding of the printing film.
