Specifically, as shown in fig. 10 and 11, the outer circumference of the support block 5 is fitted to the lumen 10 of the support tube 1, and the outer circumference has a cylindrical structure, so that it is possible to stably weave in the support tube 1.

This embodiment also discloses an infrared-heated embossing roll set, on the basis of which the heating tube 3 is further designed, as shown with reference to fig. 8-11.
The heating tube 3 is a far infrared electric heating tube 3, the tube body is a quartz tube with two closed ends, a heating wire 32 is arranged in a tube cavity 311 of the heating tube 3, and the heating wire 32 is arranged along the length direction of the heating tube 3. The middle of the heating wire 32 is provided with a heating section 321, and the heating section 321 is used for heating, so that the electric heating tube can play a role in external heating at the position; two ends of the heating section 321 are provided with leads 326, which play a role in power supply connection.
The heating section 321 is divided into a middle section 322 and two boundary sections 323 in the long and short directions, and the middle section 322 is arranged between the two boundary sections 323. The power of intermediate section 322 is evenly distributed along the length, while the power of interface section 323 increases progressively away from intermediate section 322.
When the electric heating tube heats the external hot-pressing roller, the middle section 322 is mainly used for heating, and the middle section 322 corresponds to the middle position of the pressing roller and has stable heating power. And the boundary sections 323 at the two ends of the middle section 322 adopt a variable power structure, and the power of the boundary sections 323 is gradually increased in the direction away from the middle section 322. Because the junction section 323 is close to the low-temperature areas at the two ends of the electric heating tube, the temperature at the two ends is lower, the temperature emission speed is faster, the heat emission speed at the two ends is compensated by gradually increasing power through the temperature changing structure of the junction section 323, and the temperature of the whole heating section 321 is more consistent.
The junction section 323 is provided with a low power end 325 near the middle section 322, and a high power end 324 at the end far away from the middle section 322, wherein the power of the high power end 324 is 20-30% higher than that of the low power end 325, and the temperature compensation is performed through the higher power of the high power end 324. The power change of 20-30% at both ends can compensate the temperature change of the low temperature area near both ends and maintain the overall heating effect within a proper range.
In order to maintain a stable transition state between the middle section 322 and the boundary sections 323 on both sides, the power of the low power end 325 of the boundary section 323 should be consistent with the power of the middle section 322, and the power gradually increases from the low power end 325 toward the high power end 324, so that the stable transition between the middle section 322 and the boundary sections 323 can be maintained, and abrupt power change is avoided.
The lengths of the sections of the heating wire 32 may be specifically set according to the specification parameters of the hot press roller, specifically, the length of the middle section 322 of the heating wire 32 is 400-500mm, and the length of the boundary section 323 is 250-300mm.
For the power of the heating wires 32, the total power of the heating sections 321 of the single heating wire 32 is 4-6kw, and the total power of the middle section 322 of the heating wire 32 is 2-3kw; the total power of the interface section 323 can be specifically set according to the power situation.
When the far infrared radiation electric heating tube works, the far infrared radiation electric heating tube stretches into the hot pressing roller to heat the hot pressing roller, so that the outside of the hot pressing roller reaches a certain temperature, and hot pressing processing can be realized. The heating wire 32 adopts the far infrared short wave heating wire 32, can heat the hot pressing roller with high efficiency.
Because the two ends of the hot pressing roller need to be connected with other parts such as the frame and the driving mechanism, the heat dissipation speed at the two ends of the hot pressing roller is relatively faster, and the heat dissipation at the two ends is compensated and heated by the higher power at the two ends, so that the heating state of the working area in the middle of the hot pressing roller is in a stable state.
Two tube cavities 311 are arranged in the heating tube 3, the two tube cavities 311 are separated from each other, and heating wires 32 are arranged in the two tube cavities 311. Through the mutual superposition of the two heating wires 32, the overall heating efficiency of the electric heating tube can be increased, the heating efficiency is doubled, and the power required by a single heating wire 32 is reduced.
Specifically, the heating tube 3 includes two single tubes arranged in parallel, and outer walls of the two single tubes are fixed to each other to form an integral structure. The two single tubes form two lumens 311, respectively, so that the heating tube 3 is integrally formed into a tubular structure having the other lumen 311. In addition, a recess 313 is formed at the outside of the junction of the two single pipes, and the heating pipe 3 can be positioned by the recess 313, thereby facilitating the installation of the heating pipe 3.
The heating pipe 3 is a straight pipe with two closed ends and is provided with a first end 331 and a second end 332, and a lead connector 333 is arranged at the second end 332; the wires 326 of the two heating wires 32 extend to both ends of the heating tube 3, respectively, the wires 326 at the first end 331 are connected to each other, and the wires 326 at the first end 331 are connected to the lead tab 333.
The lengths of the middle sections 322 of the two heating wires 32 are consistent, and the positions of the two heating wires are overlapped and correspond to each other; the two heated hinged ends are also identical in length and are positioned to overlap one another. The heating sections 321 of the heating wires 32 in the two tube cavities 311 are mutually overlapped, and the positions of the sections of the two heating wires 32 are mutually corresponding, so that after the two heating wires 32 are mutually overlapped, a state that the power of the middle end is uniform and the power of the two ends is gradually changed can be still formed, and the power of the heating wires 32 is controlled.
The embodiment also discloses infrared heating molding equipment, which comprises the infrared heating molding roller set in the embodiment, wherein the molding roller set can be used for carrying out imprinting treatment on the film; when the hot press die works, the plate roller and the support roller 600 rotate, the film passes between the plate roller and the support roller, the plate roller and the support roller 600 press the surfaces of the film mutually, and the textures on the hot press die 64 can be stamped on the film.
In the heating chamber 62 inside the plate roller, the plate roller is heated by the far infrared electric heating tube 3, and the plate roller is maintained at a proper temperature by the far infrared radiation, so that the film material can be heated, and further, the film material can be subjected to die pressing processing.
