[0035] See also Figure 1-6The utility model provides a technical solution: a fiber coating mechanism for producing a composite core of a sanitary product, comprising a composite core coating equipment base 1 and a composite core 22, wherein a coated fiber storage box 4 is fixedly connected to the upper end of the composite core coating equipment base 1, two brackets 7 are fixedly connected to the upper end of the composite core coating equipment base 1, a coated fiber recovery box 6 is fixedly connected to the upper end of the composite core coating equipment base 1, and a composite core coated fiber flattening assembly is arranged at the upper end of the coated fiber recovery box 6.

[0036] The composite core coated fiber flattening assembly includes two telescopic rod brackets 11, which are fixedly connected to the left and right ends of the coated fiber recovery box 6. The upper ends of the two telescopic rod brackets 11 are fixedly connected to electric telescopic rods 12, and the output ends of the two electric telescopic rods 12 are fixedly connected to roller connecting rods 17. The opposite surfaces of the two roller connecting rods 17 are rotatably connected to movable rollers 15. The upper end of the coated fiber recovery box 6 is fixedly connected to two roller brackets 13, and the surfaces of the two roller brackets 13 are provided with slide grooves 18. The two roller connecting rods 17 are respectively slidably connected to the inner walls of the corresponding slide grooves 18. The opposite surfaces of the two roller brackets 13 are rotatably connected to fixed rollers 14. The surface of the roller bracket 13 at the left end is fixedly connected to a first drive motor 16, and one end of the fixed roller 14 close to the first drive motor 16 is fixedly connected to the output end of the first drive motor 16. The upper end of the coated fiber recovery box 6 is rotatably connected to two third composite core transmission rollers 10.

[0037] Four first transmission roller brackets 2 are fixedly connected to the upper end of the composite core coating equipment base 1, two first composite core transmission rollers 23 are arranged on the upper end of the composite core coating equipment base 1, the two first composite core transmission rollers 23 are rotatably connected to the corresponding first transmission roller brackets 2 respectively, a composite core preheater 3 is fixedly connected to the upper end of the composite core coating equipment base 1, two second transmission roller brackets 5 are fixedly connected to the upper end of the composite core coating equipment base 1, and second composite core transmission rollers 24 are rotatably connected to the opposite surfaces of the two second transmission roller brackets 5.

[0038] The lower end of the coated fiber storage box 4 is fixedly connected to a coated fiber pipe 8, and a plurality of nozzles 9 are fixedly connected to the surface of the coated fiber pipe 8. The opposite surfaces of the two brackets 7 are rotatably connected to adjusting roller brackets 19 respectively, and the opposite surfaces of the two adjusting roller brackets 19 are rotatably connected to a composite core adjusting roller 21. The surface of the right bracket 7 is fixedly connected to a second drive motor 20, and the output end of the second drive motor 20 is fixedly connected to the corresponding adjusting roller bracket 19.

[0039] The composite core 22 is respectively wound on the surfaces of the corresponding third composite core drive roller 10, the fixed roller shaft 14, the movable roller shaft 15, the composite core adjustment roller shaft 21, the first composite core drive roller 23 and the second composite core drive roller 24, and the winding method is as follows: Figure 5 shown.

[0040] Furthermore, when the coating mechanism is used, the composite core 22 is wound on the surface of the coating mechanism, and the composite core 22 is wound from the surface of the third composite core driving roller 10 at the front end to the lower end of the corresponding composite core adjusting roller 21 and is wound on the surface of the four composite core adjusting rollers 21 in a "Z" shape. The second drive motor 20 is started to drive the adjusting roller bracket 19 to rotate, and the adjusting roller bracket 19 drives the four composite core adjusting rollers 21 to rotate. The four composite core adjusting rollers 21 tension the composite core 22 during rotation to adjust the tightness of the composite core 22. The tightness of the composite core 22 directly affects the degree of fit with the coating mechanism. A tighter composite core 22 will better fit with the coating mechanism, making the coating thickness more uniform. A looser core may cause uneven coating thickness or even coating peeling. Appropriate tightness can ensure the stability and continuity of the coating process, thereby improving production efficiency.

[0041] Then, it passes through the interior of the composite core preheater 3 from the upper end of another third composite core drive roller 10, passes through the interior of the coated fiber pipe 8, passes out from the lower end of the second composite core drive roller 24, passes between the fixed roller shaft 14 and the movable roller shaft 15, and finally passes out from the surface of the two third composite core drive rollers 10.

[0042] The composite core 22 is heated by the composite core preheater 3 to make the composite core 22 reach a certain temperature, and the coated fiber is evenly coated on the lower surface of the composite core 22 through the coating fiber pipeline 8 and the nozzle 9. Since the composite core 22 is preheated in advance, it is convenient for the coated fiber to fit the composite core 22. The two electric telescopic rods 12 are started to drive the roller connecting rod 17 to slide on the inner wall surface of the slide groove 18, and the spacing between the fixed roller 14 and the movable roller 15 is adjusted to facilitate the adjustment of the thickness of the coated fiber on the surface of the composite core 22. The first drive motor 16 is started to drive the fixed roller 14 to rotate. The fixed roller 14 drives the movable roller 15 to rotate through the friction between the composite core 22 and the fixed roller 14 and the movable roller 15, and rolls the composite core 22 to roll the fibers coated on the surface of the composite core 22 flat, so that the coated fibers are evenly distributed on the surface of the composite core 22.

[0043] During the rolling process of the composite core 22 by the fixed roller 14 and the movable roller 15, the thicker coated fibers will flow to the thinner positions around them, and the excess coated fibers will be scraped off by the movable roller 15 and the third composite core driving roller 10 and fall into the coated fiber recovery box 6 to be collected.

[0044] Furthermore, by moving the fixed roller 14 up and down and rotating the fixed roller 14 and the movable roller 15, the coated fibers on the surface of the composite core 22 can be rolled, so that the coating thickness of the coated fibers on the surface of the composite core 22 can be adjusted to meet different thicknesses and production requirements, and to improve the uniformity of the coated fibers, improve the practicality of the coating mechanism, and improve the production efficiency of the coating mechanism. Different fiber thicknesses can meet different application requirements and improve product appearance and quality.

[0045] By rotating the composite core adjusting roller 21, the composite core 22 rotates on the surface of the composite core adjusting roller 21 to adjust the tightness of the composite core 22. The tightness of the composite core 22 directly affects the degree of fit between the composite core 22 and the coating mechanism. A tighter composite core 22 will better fit with the coating mechanism, making the coating thickness more uniform; while a looser composite core 22 may cause uneven coating thickness or even coating peeling. Appropriate tightness can ensure the stability and continuity of the coating process, thereby improving production efficiency.

[0046] Working principle: When using the coating mechanism, the composite core 22 is wound on the surface of the coating mechanism, and the composite core 22 is wound from the surface of the third composite core driving roller 10 at the front end to the lower end of the corresponding composite core adjusting roller shaft 21 and is wound on the surface of the four composite core adjusting roller shafts 21 in a "Z" shape. The second drive motor 20 is started to drive the adjusting roller shaft bracket 19 to rotate, and the adjusting roller shaft bracket 19 drives the four composite core adjusting roller shafts 21 to rotate. The four composite core adjusting roller shafts 21 tension the composite core 22 during the rotation process to adjust the tightness of the composite core 22. The tightness of the composite core 22 directly affects the degree of fit with the coating mechanism. A tighter composite core 22 will better fit with the coating mechanism, making the coating thickness more uniform; while a looser core may cause uneven coating thickness or even coating peeling. Appropriate tightness can ensure the stability and continuity of the coating process, thereby improving production efficiency.

[0047] Then, it passes through the interior of the composite core preheater 3 from the upper end of another third composite core drive roller 10, passes through the interior of the coated fiber pipe 8, passes out from the lower end of the second composite core drive roller 24, passes between the fixed roller shaft 14 and the movable roller shaft 15, and finally passes out from the surface of the two third composite core drive rollers 10.

[0048] The composite core 22 is heated by the composite core preheater 3 to make the composite core 22 reach a certain temperature, and the coated fiber is evenly coated on the lower surface of the composite core 22 through the coating fiber pipeline 8 and the nozzle 9. Since the composite core 22 is preheated in advance, it is convenient for the coated fiber to fit the composite core 22. The two electric telescopic rods 12 are started to drive the roller connecting rod 17 to slide on the inner wall surface of the slide groove 18, and the spacing between the fixed roller 14 and the movable roller 15 is adjusted to facilitate the adjustment of the thickness of the coated fiber on the surface of the composite core 22. The first drive motor 16 is started to drive the fixed roller 14 to rotate. The fixed roller 14 drives the movable roller 15 to rotate through the friction between the composite core 22 and the fixed roller 14 and the movable roller 15, and rolls the composite core 22 to roll the fibers coated on the surface of the composite core 22 flat, so that the coated fibers are evenly distributed on the surface of the composite core 22.

[0049] During the rolling process of the composite core 22 by the fixed roller 14 and the movable roller 15, the thicker coated fibers will flow to the thinner positions around them, and the excess coated fibers will be scraped off by the movable roller 15 and the third composite core driving roller 10 and fall into the coated fiber recovery box 6 to be collected.

[0050] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
