The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] See also Figure 1 and Figure 2 A non-woven fabric processing equipment comprises a preheating and pressing mechanism 100, a drying room 200, a hot and cold pressing mechanism 300 and a material receiving mechanism 400 which are arranged in sequence, wherein the preheating and pressing mechanism 100 comprises a first chassis 110, a first hot pressing roller group 120 and a first silicone pressing roller 130, wherein the first hot pressing roller group 120 and the first silicone pressing roller 130 are both arranged on the first chassis 110, the first hot pressing roller group 120 comprises a first main hot pressing roller 121 and a first auxiliary hot pressing roller 122, the first main hot pressing roller 121 is transmission-connected with the first auxiliary hot pressing roller 122, the first silicone pressing roller 130 is arranged in contact with the first main hot pressing roller 121 or the first auxiliary hot pressing roller 122, and the first main hot pressing roller 121 or the first auxiliary hot pressing roller 122 drives the first silicone pressing roller 130 to rotate.

[0022] Specifically, when the non-woven cotton web is produced and processed, the non-woven cotton web is first combed by a cotton carding machine and a combing machine, and then sequentially transmitted to the preheating and pressing mechanism 100 for preheating, and then transported to the drying room 200 for baking, and finally transported to the hot and cold pressing mechanism 300 for flattening, and finally the completed non-woven cotton web is rolled up by the receiving mechanism 400 to realize the production and processing of the non-woven cotton web.

[0023] When the non-woven cotton web is preheated, the non-woven cotton web first passes between the first main hot pressing roller 121 and the first auxiliary hot pressing roller 122, and is squeezed against each other by the first main hot pressing roller 121 and the first auxiliary hot pressing roller 122, so that the non-woven cotton web reaches preliminary pre-pressing and shaping. At the same time, the first main hot pressing roller 121 and / or the first auxiliary hot pressing roller 122 are fitted with a first silicone pressing roller 130, and the first main hot pressing roller 121 or the first auxiliary hot pressing roller 122 is pressed against the first silicone pressing roller 130. The first silicone pressing roller 130 has a certain flexibility. Therefore, during the pressing, the space for the internal fibers of the non-woven cotton web is retained, and the essence of the non-woven cotton web is not damaged, so that its structure can be better fixed, and the shrinkage of the non-woven cotton web is stabilized, and the thickness of the non-woven cotton web is made more uniform, so as to improve the quality of the non-woven cotton web during processing.

[0024] In addition, in order to realize the transmission of the first hot pressing roller group 120 and the first silicone pressing roller 130, a motor can be arranged at the first chassis 110, and the first main hot pressing roller 121 is driven to rotate by the motor. At the same time, the first main hot pressing roller 121 is cross-connected with the first auxiliary hot pressing roller 122 through a chain or belt to realize cross transmission. When the first main hot pressing roller 121 rotates, it drives the first auxiliary hot pressing roller 122 to rotate in the opposite direction, thereby realizing the pressure transmission of the non-woven cotton web, and the first silicone pressing roller 130 is attached to the first main hot pressing roller 121 and / or the first auxiliary hot pressing roller 122. Therefore, when the first main hot pressing roller 121 and the first auxiliary hot pressing roller 122 rotate, the non-woven cotton web is transported and the first silicone pressing roller 130 is driven to rotate.

[0025] See also Figure 3 The drying room 200 includes a mesh belt conveyor assembly 210 and an oven 220. The mesh belt conveyor assembly 210 includes a front frame 211, a rear frame 212 and a conveyor mesh belt 213. The front frame 211 is arranged between the preheating and pressing mechanism 100 and the oven 220, and the rear frame 212 is arranged between the oven 220 and the hot and cold pressing mechanism 300. The conveyor mesh belt 213 runs through the oven 220, and the two ends are respectively connected to the front frame 211 and the rear frame 212. The front frame 211 is provided with a rotating motor (not shown in the figure), and the rotating motor drives the conveyor mesh belt 213 to rotate in a cycle.

[0026] In this embodiment, after the non-woven cotton web is preliminarily pre-pressed and fixed by the preheating and pressing mechanism 100, it is transported to the front frame 211 and laid flat on the conveyor mesh belt 213. The conveyor mesh belt 213 is driven by the rotating motor to rotate in a cycle, and the non-woven cotton web laid flat on the conveyor mesh belt 213 is transported to the oven 220. The high temperature of the oven 220 fuses and fixes the internal fibers of the non-woven cotton web to meet the stiffness requirement. The non-woven cotton web is then transported out of the oven 220 through the conveyor mesh belt 213 and to the rear frame 212. Finally, the stiffness of the non-woven fabric reaches the production requirement through the drying room 200, and its production quality is improved.

[0027] For further information, see Figure 4The hot and cold pressing mechanism 300 includes a second chassis 310, a second hot pressing roller group 320, a cold pressing roller group 330 and a second silicone pressing roller 340. The second hot pressing roller group 320, the cold pressing roller group 330 and the second silicone pressing roller 340 are all installed on the second chassis 310, and the cold pressing roller group 330 is arranged at one end of the second hot pressing roller group 320. The second hot pressing roller group 320 includes a second main hot pressing roller 321 and a second auxiliary hot pressing roller 322. The second main hot pressing roller 321 and the second auxiliary hot pressing roller 322 are transmission-connected. The second silicone pressing roller 340 is arranged in contact with the second main hot pressing roller 321 or the second auxiliary hot pressing roller 322, and is driven to rotate by the second main hot pressing roller 321 or the second auxiliary hot pressing roller 322. The cold pressing roller group 330 includes a main cold pressing roller 331 and an auxiliary cold pressing roller 332. The main cold pressing roller 331 and the auxiliary cold pressing roller 332 are transmission-connected.

[0028] After the non-woven cotton web is fused and solidified in the drying room 200, the non-woven cotton web is then conveyed to the hot and cold pressing mechanism 300, and the non-woven cotton web first passes between the second main hot pressing roller 321 and the second auxiliary hot pressing roller 322, and is hot pressed again. The structure of the pressed non-woven cotton web is stabilized by the second main hot pressing roller 321 and the second auxiliary hot pressing roller 322, and then the non-woven cotton web is conveyed to the cold pressing roller group 330, and is pressed by the main cold pressing roller 331 and the auxiliary cold pressing roller 332 to solidify the non-woven cotton web. Finally, the flatness and stiffness of the produced non-woven cotton web can meet the production requirements, and the thickness is uniform and the surface is smooth.

[0029] In addition, before the non-woven cotton web is conveyed from the second hot pressing roller group 320 to the cold pressing roller group 330, the non-woven cotton web will be squeezed by the second silicone pressing roller 340 and the second main hot pressing roller 321 or the second auxiliary hot pressing roller 322. The flexible second silicone pressing roller 340 and the hard second main hot pressing roller 321 or the second auxiliary hot pressing roller 322 will press the non-woven cotton web against each other, so that the non-woven cotton web will not be excessively squeezed and the flatness of the web surface will not be damaged, thereby ensuring that the flatness and stiffness of the non-woven cotton web meet production requirements.

[0030] The transmission mode of the second hot pressing roller group 320 and the hot and cold pressing roller group 330 is the same as that of the first hot pressing roller group 120, that is, cross transmission is adopted.

[0031] See also Figure 5 The receiving mechanism 400 includes a frame 410 and a receiving roller 420 arranged on the frame 410, a receiving motor 430 is arranged below the frame 410, and the output end of the receiving motor 430 is connected to a rotating shaft 440, and the rotating shaft 440 is connected to the receiving roller 420 through a belt 450.

[0032] In this embodiment, the structure of the material receiving mechanism 400 is simple. A material receiving roller 420 is arranged on the frame 410, and the material receiving roller 420 can be rotated by the material receiving motor 430. When receiving the material, the material receiving motor 430 works to drive the rotating shaft 440 to rotate, and the rotating shaft 440 drives the material receiving roller 420 to rotate through the belt 450. While the material receiving roller 420 rotates, the non-woven cotton web is collected to realize automatic material receiving.

[0033] In the whole process of non-woven cotton web processing and production, the starting end of the non-woven cotton web is manually passed through the preheating and pressing mechanism 100, the drying room 00, the hot and cold pressing mechanism 300 and fixed on the receiving roller 420 of the receiving mechanism 400, and then each mechanism is started for automatic conveying production, and each mechanism is operated synchronously, so that the processing of the non-woven cotton web is finally reasonable.

[0034] Finally, see Figure 2 The first silicone laminating roller 130 and the second silicone laminating roller 340 are each provided with at least one, and the first silicone laminating roller 130 and the second silicone laminating roller 340 can be moved on the first chassis 110 and the second chassis 310 respectively through the cylinder 500.

[0035] In order to make the mesh surface of the non-woven cotton web smoother and brighter, a plurality of first silicone pressing rollers 130 and a plurality of second silicone pressing rollers 340 may be provided, and a plurality of first silicone pressing rollers 130 may be pressed against the first main hot pressing roller 121 or the first auxiliary hot pressing roller 122, and a plurality of second silicone pressing rollers 340 may be pressed against the second main hot pressing roller 321 or the second auxiliary hot pressing roller 322. Since the first silicone pressing roller 130 and the second silicone pressing roller 340 are made of silicone material and have a certain flexibility, the non-woven cotton web will not be excessively squeezed during pressing, and uneven stretching of the non-woven cotton web will not be caused. The non-woven cotton web structure is stable, the mesh surface is smooth and bright, and the production quality of the non-woven cotton web is improved.

[0036] The first silicone laminating roller 130 and the second silicone laminating roller 340 can be moved on the first chassis 110 and the second chassis 310 respectively by the cylinder 500, and the distance between the first silicone laminating roller 130 and the first main hot pressing roller 121 or the first auxiliary hot pressing roller 122 can be adjusted by the cylinder 500, and the distance between the second silicone laminating roller 340 and the second main hot pressing roller 321 or the second auxiliary hot pressing roller 322 can be adjusted, so as to achieve the desired pressing of non-woven cotton webs of different thicknesses.

[0037] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Any technician in this industry can smoothly implement the present invention as shown in the drawings of the specification and described above; however, any technician familiar with this profession can make some changes, modifications and equivalent changes made by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, which are all equivalent embodiments of the present invention; at the same time, any changes, modifications and evolutions of any equivalent changes made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
