Description

Technical Field

[0001] This utility model relates to the field of opening machine technology, specifically a fiber separation device for opening nonwoven fabrics. Background Technology

[0002] An opening machine is a pretreatment device used in the textile industry. It is mainly used to loosen tightly packed fiber raw materials into a loose state through mechanical action such as tearing, hitting or combing, while removing some impurities and short fibers, so as to provide a uniform fiber flow for subsequent combing and spinning processes.

[0003] In the prior art, the patent announcement number CN215800473U discloses an opening machine for non-woven fabric processing, including a base, a support leg and an opening box fixedly installed on the top of the base, a feeding box fixedly installed on the top of the support leg, a first conveying device inside the feeding box, an installation box fixedly installed on the top of the feeding box, and a first opening roller and a second opening roller movably connected inside the opening box.

[0004] The rotation of the opening roller allows for effective tearing or fine combing of fiber raw materials, thus achieving the opening function. However, during the opening process, some fiber confinement inevitably becomes entangled on the comb teeth of the opening roller. Over time, these fibers accumulated on the comb teeth hinder the normal rotation of the opening roller and severely affect the overall performance and efficiency of the opening machine. To solve this problem, during regular maintenance, workers need to carefully disassemble the equipment casing and use specialized tools to thoroughly clean the fibers from the comb teeth. This step is quite tedious. Therefore, a fiber separation device for nonwoven fabric opening machines is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a fiber separation device for a nonwoven fabric opening machine to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiber separation device for opening and separating nonwoven fabrics, comprising an opening box, a first opening roller rotatably mounted on the upper end of the opening box, an inspection port provided on the side wall of the opening box, a sealing cover threaded into the inspection port, a second opening roller rotatably mounted on the opening box, the second opening roller comprising an opening roller body rotatably mounted inside the opening box, a movable groove provided inside the opening roller body, a movable plate slidably mounted in the movable groove, comb teeth fixedly mounted on the movable plate, and a winding mechanism installed inside the opening roller body.

[0007] Preferably, the bottom of the opening roller body is provided with a positioning hole, a spring guide rod is slidably installed in the positioning hole, a return spring is sleeved on the spring guide rod, and the upper end of the spring guide rod is fixedly installed on the movable plate.

[0008] Preferably, the surface of the opening roller body is provided with inlet and outlet holes, and the comb teeth extend out of the opening roller body through the inlet and outlet holes.

[0009] Preferably, the movable plate is movably installed in the opening roller body through a movable groove, the spring guide rod is movably installed in the opening roller body through a positioning hole, one end of the return spring is connected to the movable plate, and the other end of the return spring is connected to the bottom of the movable groove.

[0010] Preferably, the winding mechanism includes a movable shaft and a drive shaft rotatably mounted in the body of the opening roller. A winding reel is fixedly mounted at one end of the movable shaft, and a cable is installed between the winding reel and the movable plate. A large gear is fixedly mounted at the other end of the movable shaft, and a small gear is fixedly mounted at the end of the drive shaft. A locking plate is sleeved on the drive shaft, and a locking nut is threadedly connected to one side of the opening roller body.

[0011] Preferably, a threaded groove is provided on one side of the opening roller body, and the locking nut is connected to the opening roller body through the threaded groove.

[0012] Preferably, one end of the cable is fixed to the winding reel, and the other end of the cable is fixedly installed on the movable plate. The large gear is rotatably installed in the body of the opening roller via a movable shaft, and the small gear is rotatably installed in the body of the opening roller via a drive shaft, with the small gear meshing with the large gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, the return spring provides a forward driving force to the movable plate, causing it to move forward. After the movable plate moves forward, it drives the comb teeth to move forward, thereby causing the comb teeth to extend out of the opening roller body. During the rotation of the opening roller body, the comb teeth extending out of the opening roller body comb the fibers to achieve the opening function.

[0015] 2. In this application, after the drive shaft is unlocked, it can rotate. When the drive shaft rotates, it drives the connected pinion to rotate synchronously; the rotation of the pinion then drives the meshing large gear to rotate; the rotation of the large gear drives the movable shaft to rotate; the rotation of the movable shaft causes the take-up reel to rotate, thus enabling the take-up reel to take up the cable. When the cable is taken up by the take-up reel, it pulls the movable plate towards the bottom of the movable chute, causing the comb teeth to retract into the opening roller body, ultimately achieving rapid separation of the fiber from the comb teeth.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a fiber separation device for a nonwoven fabric opening machine, including an opening box 1, a first opening roller 4 rotatably mounted on the upper end of the opening box 1, an inspection port 2 opened on the side wall of the opening box 1, a sealing cover 3 threaded into the inspection port 2, a second opening roller 5 rotatably mounted on the opening box 1, and a winding mechanism 6 installed inside the opening roller body 501. Through the cooperation of the winding mechanism 6 and the comb teeth 502, the fiber can be quickly separated from the comb teeth 502.

[0024] like Figure 2 and Figure 3As shown, the second opening roller 5 includes an opening roller body 501 rotatably installed in the opening box 1. The opening roller body 501 has a movable groove 503, and a movable plate 506 is slidably installed in the movable groove 503. A comb tooth 502 is fixedly installed on the movable plate 506. A positioning hole 507 is opened at the bottom of the opening roller body 501. A spring guide rod 505 is slidably installed in the positioning hole 507. A reset spring 504 is sleeved on the spring guide rod 505, and the upper end of the spring guide rod 505 is fixedly installed on the movable plate 506. An inlet and outlet hole is opened on the surface of the opening roller body 501, and the comb tooth 502 extends out of the opening roller body 501 through the inlet and outlet hole.

[0025] Specifically, the return spring 504 provides a continuous and stable pushing force to the movable plate 506. This pushing force ensures that the movable plate 506 can move smoothly forward along a predetermined trajectory. When the movable plate 506 begins to move forward under the action of the return spring 504, it drives the comb teeth 502 to move forward together, allowing them to smoothly extend beyond the opening roller body 501. During the continuous rotation of the opening roller body 501, these extended comb teeth 502 will come into close contact with the fiber material and perform effective combing work, thereby significantly improving the looseness and uniformity of the fibers. The return spring 504, the movable plate 506, and the comb teeth 502 together realize the opening function of the opening roller body 501.

[0026] like Figure 4 and Figure 5 As shown, the winding mechanism 6 includes a movable shaft 603 and a drive shaft 607 rotatably mounted inside the opening roller body 501. A winding reel 602 is fixedly mounted at one end of the movable shaft 603, and a cable 601 is installed between the winding reel 602 and the movable plate 506. A large gear 604 is fixedly mounted at the other end of the movable shaft 603, and a small gear 605 is fixedly mounted at the end of the drive shaft 607. A locking piece 608 is sleeved on the drive shaft 607. A locking nut 606 is threadedly connected to one side of the opening roller body 501. A threaded groove is opened on one side of the opening roller body 501, and the locking nut 606 is connected to the opening roller body 501 through the threaded groove.

[0027] Specifically, after successfully releasing the locking state of the drive shaft 607, the operator can manually rotate the drive shaft 607. As the drive shaft 607 rotates, the pinion 605 also begins to rotate. The rotation of the pinion 605 further transmits power, driving the meshing large gear 604 to rotate. The rotation of the large gear 604 drives the movable shaft 603 to rotate synchronously. The rotation of the movable shaft 603 then drives the take-up reel 602 to rotate, achieving the take-up function. As the cable 601 is gradually wound up by the take-up reel 602, the cable 601 pulls the movable plate 506. Under the tension of the cable 601, the movable plate 506 retracts along a preset path, eventually moving to the bottom position of the movable chute 503. This series of mechanical actions ultimately causes the comb teeth 502 to retract into the internal space of the opening roller body 501. The retraction of the comb teeth 502 ensures rapid and effective separation between the fiber material and the comb teeth 502.

[0028] Working principle: The return spring 504 provides forward power to the movable plate 506, allowing the movable plate 506 to move forward. After the movable plate 506 moves forward, it will drive the comb teeth 502 to move forward, so that the comb teeth 502 extend beyond the opening roller body 501. The comb teeth 502 extending beyond the opening roller body 501 will comb the fibers during the rotation of the opening roller body 501, realizing the opening function. When the comb teeth 502 are wrapped with a large amount of fiber, the sealing cover 3 can be opened. Then, the locking nut 606 can be loosened and the locking piece 608 can be removed, thereby releasing the lock of the drive shaft 607. After the lock of the drive shaft 607 is released, the drive shaft 607 can be rotated. The drive shaft 607 will then drive the pinion 605 to rotate. After the pinion 605 rotates, it will drive the gear 604 to rotate. After the gear 604 rotates, it will drive the movable shaft 603 to rotate. After the movable shaft 603 rotates, it will drive the take-up reel 602 to rotate, thereby causing the take-up reel 602 to take up the cable 601. After the cable 601 is taken up by the take-up reel 602, it will pull the movable plate 506 to retract to the bottom of the movable chute 503, so that the comb teeth 502 retract into the opening roller body 501, realizing the rapid separation of the fiber from the comb teeth 502.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
