Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to wet process equipment for filling non-woven fabric with resin. Background Art

[0002] Non-woven fabric is a kind of fabric that does not require spinning and weaving. It has the characteristics of moisture-proof, breathable, flexible, thin, flame retardant, non-toxic and odorless, low price, recyclable, etc. It can be used in different industries, such as sound insulation, heat insulation, electric heaters, masks, clothing, medical, filling materials, etc. The production process of non-woven fabric is just to orient or randomly support textile staple fibers or filaments to form a fiber mesh structure, and then fix it by mechanical, hot bonding or wet methods. In some fields such as medical, construction, packaging, etc., resin will be added to non-woven fabrics to enhance the strength, durability or over-frequency performance of non-woven fabrics.

[0003] After the existing non-woven fabric wet-process equipment sprays molten resin on the surface of the non-woven fabric, it needs to be extruded to squeeze out the excess resin attached to the surface. After extrusion, more resin often adheres to the surface of the extrusion roller. If these resins are not cleaned in time, they will affect the normal work of the extrusion roller after cooling, affect the molding of the non-woven fabric, and cause waste. For this reason, we propose a wet-process equipment for non-woven fabric filling with resin. Utility Model Content

[0025] Furthermore, the tension adjustment mechanism 3 includes a mounting plate 12, a mounting groove 13, a threaded rotating rod 14 and a mounting block 15. Two symmetrically distributed mounting plates 12 are fixedly connected to one end of both sides of the shell 1 close to the feed port. Two mounting grooves 13 are provided on the upper surface of the mounting plate 12. A threaded rotating rod 14 is movably inserted at the bottom of the mounting groove 13. A mounting block 15 is threadedly connected to the threaded rotating rod 14 in the inner cavity corresponding to the tension adjustment mechanism 3.

[0026] Furthermore, the mounting groove 13 is communicated with the inner cavity of the housing 1 , and the four mounting blocks 15 all extend into the inner cavity of the housing 1 , and a tension adjustment roller 7 is rotatably connected between two symmetrical mounting blocks 15 .

[0027] Furthermore, the resin cleaning device 10 includes a scraper 11, a connecting piece 16, an arc-shaped mounting plate 17, a scraper 2 18 and a conveying path 19. The two extrusion rollers 9 are symmetrically distributed up and down. The scraper 11 is fixedly connected to the inner walls on both sides of the shell 1, and the two ends of the upper extrusion roller 9 are fixedly connected to the connecting piece 16. One end of the two connecting pieces 16 is fixedly connected to the arc-shaped mounting plate 17 on the principle that the extrusion roller 9 has one end, and the scraper 2 18 is fixedly connected to the lower end of the inner wall of the arc-shaped mounting plate 17. The conveying path 19 is fixedly connected to the lower end of the arc-shaped mounting plate 17 away from the extrusion roller 9.

[0028] Furthermore, the upper surfaces of the scraper 1 11 and the scraper 2 18 are respectively in contact with the side surfaces of the two squeezing rollers 9 , and a through groove communicating with the conveying path 19 is formed at the lower end of the inner wall of the arc-shaped mounting plate 17 .

[0029] Furthermore, the inner wall of the bottom side of the conveying path 19 is inclined from the middle to both ends.

[0030] Working principle: When the device is needed to spray resin on non-woven fabrics, the non-woven fabric fiber raw material is wound through two tension adjustment rollers 7, then wound through the auxiliary roller 8 and extended to the outside through the two squeezing rollers 9. When the tension of the non-woven fabric fiber raw material needs to be adjusted in the device, the threaded rotating rod 14 in the mounting plate 12 at both ends is rotated, and the mounting block 15 connected thereto is moved by rotating the threaded rotating rod 14 through a threaded transmission. The height difference between the two tension adjustment rollers 7 is adjusted by adjusting the height of the mounting blocks 15 at both ends of the two tension adjustment rollers 7, so as to adjust the tension of the non-woven fabric fiber raw material. By adjusting the tension, the non-woven fabric fiber raw material will not be wrinkled when the resin is sprayed on the coating head 5, and the resin melt can be more evenly covered; the non-woven fabric that has been sprayed passes between the two squeezing rollers 9 to remove excess The resin is extruded, and the extruded resin falls into the resin storage pool 6. When the extrusion rollers 9 rotate, a part of the resin bonded to the two extrusion rollers 9 is scraped off by the scraper 11 at the lower end of the extrusion roller 9 and falls into the resin storage pool 6. The scraper 2 18 at the upper end scrapes the resin on the upper extrusion roller 9 into the cavity between the arc-shaped mounting plate 17 and the extrusion roller 9. Under the action of gravity, the scraped resin falls into the conveying path 19 and passes through the inclined bottom surface of the conveying path 19 through the two ends of the conveying path 19 and falls into the resin storage pool 6. The bottom surface inclined toward the two ends between the arc-shaped mounting plate 17 and the conveying path 19 can prevent the upper end of the resin from being scraped off and falling on the non-woven fabric, causing damage to the non-woven fabric; the resin melt collected in the resin storage pool 6 can be timely pumped into the laminating head 5 by the resin pump 2 for recycling to avoid waste.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
