[0024] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0025] The terms "top surface", "bottom surface" and "underside" are based on the normal use state of the heat setting device and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0026] like Figure 1 and 2 As shown, a heat setting device for the production of high-strength composite non-woven fabrics includes a mounting bracket 1, on which a heating roller 2 is rotatably arranged, and both ends of the heating roller 2 are rotatably connected to the mounting bracket 1 through a connecting ring 32, and a plurality of spliced ​​insulation plates 31 distributed around the heating roller 2 are detachably connected between the two connecting rings 32, and the spliced ​​insulation plates 31 and the connecting rings 32 are combined to form a heat preservation cover 3 that completely or partially covers the heating roller 2.

[0027] The above-mentioned heat setting device is used to heat press the non-woven fabric that has been produced to enhance the density and strength of the non-woven fabric, improve the appearance and feel, and improve the processing performance, so that it is suitable for various application scenarios; when in use, at least two heating rollers 2 are installed on the mounting bracket 1, and the non-woven fabric can bypass the two heating rollers 2 in turn and pass between the two heating rollers 2, or directly pass between the two heating rollers 2, so that the non-woven fabric is heated and extruded by the heating roller 2 to achieve heat setting of the non-woven fabric; in this process, a plurality of spliced ​​insulation plates 31 are fixed around the heating roller 2 by a connecting ring 32, and a gap is left between the spliced ​​insulation plates 31 and the outer surface of the heating roller 2 for the non-woven fabric to pass through. By covering the heating roller 2 with the spliced ​​insulation plates 31, the heat loss on the heating roller 2 can be reduced, and the energy-saving performance of the equipment can be improved. At the same time, the uniformity of heating of the heating roller 2 can also be improved, and the heat pressing effect on the non-woven fabric can be improved.

[0028] The heat preservation cover 3 of the above-mentioned heat setting device is composed of a plurality of spliced ​​heat preservation plates 31. By controlling the number and installation positions of the spliced ​​heat preservation plates 31, the coverage range of the spliced ​​heat preservation plates 31 on the surface of the heating roller 2 can be effectively controlled, thereby leaving a channel for the non-woven fabric to enter and exit, and also leaving space at the contact part of the two heating rollers 2. By relying on the flexible installation of the heat preservation plates 31, the normal use of the heating roller 2 can be maintained without affecting the heat preservation of the heating roller 2, thereby greatly improving the practicality of the heat setting device.

[0029] A further improvement is, Figure 1 , 3 As shown in 6, the heating roller 2 includes a fixed roller and a movable roller parallel to each other, and both ends of the movable roller are slidably connected to the mounting bracket 1 through a synchronous displacement mechanism; the synchronous displacement mechanism includes a slide groove 104 opened on the mounting bracket 1 along the radial direction of the fixed roller and a movable seat 103 slidingly matched with the slide groove 104, the end of the movable roller is rotatably connected to the movable seat 103 through a connecting ring 32, and the mounting bracket 1 is provided with a hydraulic cylinder 105 transmission-connected to the movable seat 103. The heating roller 2 is divided into a fixed roller fixed to the mounting bracket 1 and a movable roller connected to the movable seat 103. When the non-woven fabric passes between the fixed roller and the movable roller, the movable roller can slide to adjust the gap between it and the fixed roller, adjust the pressure of hot pressing on the non-woven fabric, thereby improving the effect of heat setting on the non-woven fabric; when the movable roller moves, the two movable seats 103 are pushed to move synchronously along the two slide grooves 104 on the mounting bracket 1 by the hydraulic cylinder 105, thereby realizing the adjustment of the position of the movable roller; in actual use, the side walls of the slide groove 104 on both sides are provided with positioning grooves 106 along the moving direction of the movable seat 103, and the movable seat 103 is provided with a positioning block 107 that slides with the positioning groove 106. Through the guiding and limiting effects of the positioning block 107 and the positioning groove 106, the stability of the movable seat 103 can be improved, and finally the stability of the movable roller can be improved.

[0030] A further improvement is, Figure 4 and 5 As shown, the end of the heating roller 2 is connected to the inner wall of the connecting ring 32 through a bearing 323, and the outer peripheral surface of the connecting ring 32 is provided with a plurality of plug ports 321 at equal intervals around its own axis, and the end of the spliced ​​insulation board 31 is provided with a plug connector 312 that is plugged with the plug connector 321. The spliced ​​insulation board 31 is installed and fixed by plugging the plug connectors 312 at both ends of the spliced ​​insulation board 31 with the plug connectors 321 at both ends of the heating roller 2, which greatly improves the convenience of disassembly and assembly of the spliced ​​insulation board 31.

[0031] A further improvement is, Figure 4As shown, the plug ports 321 are distributed along the radial direction of the connecting ring 32. When the spliced ​​insulation board 31 is assembled and disassembled, the radially distributed plug ports 321 and the plug connectors 312 can limit the radial movement of the spliced ​​insulation board 31 along the connecting ring 32, thereby reducing the interference between the spliced ​​insulation board 31 and the adjacent spliced ​​insulation board 31 during the disassembly and assembly, and improving the convenience of the spliced ​​insulation board 31 during the disassembly and assembly.

[0032] A further improvement is, Figure 4 As shown, a second threaded hole 322 connected to the plug port 321 is provided on the side of the connecting ring 32, and a set screw for locking the plug connector 312 is threadedly connected to the second threaded hole 322. The set screw inside the second threaded hole 322 abuts against the plug connector 312 plugged into the plug port 321, so as to lock the plug connector 312, thereby improving the firmness of the connection between the spliced ​​insulation board 31 and the connecting ring 32, and preventing the two from being separated during use.

[0033] A further improvement is, Figure 3 and 4 As shown, the movable seat 103 and the mounting bracket 1 are both provided with a mounting hole 101, a flange 324 is circumferentially arranged on the outer periphery of the connecting ring 32, a plurality of positioning holes 325 are circumferentially evenly spaced around the axis of the connecting ring 32 on the flange 324, a plurality of first threaded holes 102 are circumferentially evenly spaced around the axis of the mounting hole 101, the number of the first threaded holes 102 is an integer multiple of the number of the positioning holes 325, and the positioning holes 325 are connected to the first threaded holes 102 by bolts. By bolting the positioning hole 325 and the first threaded hole 102, a fixed connection between the connecting ring 32, the movable seat 103 and the mounting bracket 1 can be achieved, and then the heating roller 2 and the spliced ​​insulation board 31 can be installed and fixed through the connecting ring 32. The number of the first threaded holes 102 is an integer multiple of the number of the positioning holes 325. The positioning hole 325 can be connected to different first threaded holes 102 to adjust the installation position of the connecting ring 32, and then the position of each spliced ​​insulation board 31 can be fine-tuned, so as to control the range and position of the spliced ​​insulation board 31 covering the heating roller 2, thereby facilitating the connection between the non-woven fabric and the heating roller 2, and the connection between the heating roller 2 and the heating roller 2.

[0034] A further improvement is, Figure 1 and 2 As shown, two adjacent spliced ​​insulation boards 31 are sealed and connected, and the spliced ​​insulation board 31 is sealed and connected to the connecting ring 32. Silicone foam strips can be arranged between the spliced ​​insulation boards 31 and between the spliced ​​insulation boards 31 and the connecting ring 32. The silicone foam strips have good insulation and sealing properties, thereby improving the insulation performance of the spliced ​​insulation board 31 on the heating roller 2, and improving the energy-saving performance and heating uniformity of the heating roller 2.

[0035] A further improvement is, Figure 5 As shown, reinforcing ribs 311 are provided on the spliced ​​insulation board 31 along the axis of the heating roller 2. When the heating roller 2 is long, in order to adapt to the heating roller 2, the spliced ​​insulation board 31 also needs to be long, which makes the spliced ​​insulation board 31 easy to bend; the provided reinforcing ribs 311 can effectively improve the strength of the spliced ​​insulation board 31 to prevent it from bending, so as to reduce the equipment failure rate.
