Description

Technical Field

[0001] The utility model relates to the technical field of nylon twisting, in particular to a nylon fiber spinning twisting device. Background Art

[0002] Nylon is the trade name of polyamide fiber, also known as "nylon". By fixing one end of the nylon monofilament and rotating the other end, the nylon can be twisted into yarn. The twisted nylon yarn can improve the strength, elasticity and other physical properties of the yarn. Artificial twisting efficiency is low. The industrial production of nylon uses a twisting device to rotate and twist the yarn to obtain the required twist, thereby enhancing the strength and durability of the yarn. Nylon twisting is an important link in the nylon textile process.

[0003] When the twisting machine is in use, the yarn formed by twisting the nylon monofilament will be rewound on the reel. After one roll is wound up, the reel needs to be removed in time and replaced with a new one. In order to make the reel more stable, more structures are generally used to fix the reel, which makes the reel disassembly and assembly operation more troublesome.

[0004] In order to solve the above problems, there is an existing public technical solution, with announcement number CN220352316U disclosing a chemical fiber twisting machine, which improves the work efficiency of disassembling and assembling the reel by cooperating with a rotating shaft, a convex strip, a groove and a locking nut on the twisting machine.

[0005] However, when the above-mentioned chemical fiber twisting machine is in use, each group of reels is individually installed on the rotating shaft through a locking nut. When the twisting machine is twisting nylon monofilament, in order to improve work efficiency, the twisting machine mostly operates multiple groups of reels synchronously at the same time, and disassembly and assembly also require disassembly and assembly of multiple groups of reels together. In this way, the locking nuts on the reels are removed one by one, which is inefficient. In view of this, a twisting device for nylon fiber spinning is provided to overcome the above-mentioned defects. Summary of the invention

[0028] The reel clamping assembly 6 includes a servo motor 603 fixedly mounted on the twisting machine housing 1 by screws, the power output end of the servo motor 603 is connected to a driving gear 602, and a lifting screw 606 is fixedly connected to the lower part of the driving gear 602, a lifting slider 605 is installed on the outside of the lifting screw 606 through a screw nut, and a lifting rod 601 parallel to the reel rotating base 2 is arranged on one side of the lifting slider 605, and a plurality of equidistant and evenly distributed lower pressure plates 604 are vertically mounted on the front and rear ends of the lifting rod 601, a circular hole is opened inside the lower pressure plate 604, and the circular hole in the lower pressure plate 604 is adapted to the outer dimensions of the reel placing rod 3, and the reel placing rod 3 and the lower pressure plate 604 are arranged in a one-to-one correspondence.

[0029] By adopting the above technical scheme, firstly, when in use, the twisting reels are directly sleeved one by one on the reel placement rod 3. After the sleeve is completed, the servo motor 603 can be started. The servo motor 603 drives the active gear 602 to rotate and drives the lifting screw rod 606 to rotate. Then the lifting slider 605 on the lifting screw rod 606 drives the entire lifting rod 601 to move up and down on the twisting machine housing 1 through the screw nut, and drives all the lower pressure plates 604 to move downward through the lifting rod 601. Gradually, the lower pressure plate 604 approaches the twisting reel until the lower pressure plate 604 passes through the reel placement rod 3 and abuts against the twisting reel. The bottom of the reel rotating base 2 can be installed with a driving mechanism motor and other equipment to drive the reel rotating base 2 to rotate. The reel rotating base 2 can drive the twisting reel to rotate to twist the nylon monofilament.

[0030] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the lateral support rod assembly 5 includes a passive gear 505 arranged on one side of the active gear 602 and meshing with the active gear 602, a transmission rack 503 is meshingly connected to one side of the passive gear 505 and the active gear 602, and one end of the transmission rack 503 is fixedly connected to a sliding rod 504, a sliding groove is provided at the connection between the sliding rod 504 and the support plate 4, and the sliding rod 504 passes through the support plate 4 through the sliding groove, a side of the sliding rod 504 away from the axis of the lifting screw rod 606 is vertically provided with a plurality of equidistant and evenly distributed connecting rods 507, and a movable roller 502 is fixed to the end of the connecting rod 507, a supporting roller 506 is sleeved on the outside of the movable roller 502, and a fixed roller 501 with a hollow structure is provided on the other side of the movable roller 502, one end of the fixed roller 501 is movably sleeved with the movable roller 502, and the other end of the fixed roller 501 is fixed on the support plate 4, and a connecting groove is provided at the connection between the support roller 506 and the connecting rod 507.

[0031] By adopting the above technical solution, while the twisting reel is installed on the reel placement rod 3, the nylon monofilament reel is installed and the nylon monofilament reel is passed on the fixed roller 501. When the active gear 602 rotates, the passive gear 505 is driven to rotate under the action of the teeth. At this time, the passive gear 505 and the active gear 602 rotate in opposite directions, and the transmission rack 503 located at the rear end of the passive gear 505 and the front end of the active gear 602 slide synchronously, and then the transmission rack 503 is rotated. The connecting rod 507 is driven to slide by the sliding rod 504, and the connecting rod 507 pulls the movable roller 502 to slide inside the supporting roller 506, so that the movable roller 502 and the fixed roller 501 are mutually connected, so as to realize the installation of the nylon monofilament reel. At the beginning of the whole work, when the lower pressure plate 604 is away from the reel placement rod 3, the movable roller 502 is also away from the fixed roller 501. As the lower pressure plate 604 and the reel placement rod 3 approach each other, the movable roller 502 also approaches the fixed roller 501.

[0032] Working principle: when the twisting reel and the nylon monofilament reel are installed on the reel placement rod 3 and the support plate 4 respectively, the servo motor 603 is started, and the transmission rack 503 is moved synchronously by utilizing the transmission effect of the passive gear 505 and the active gear 602, so as to drive the sliding rod 504 to move. When the active gear 602 moves, the lifting screw rod 606 can be driven to rotate, so that the lower pressure plate 604 presses the twisting reel downward, and the movable roller 502 gradually approaches the fixed roller 501, and the nylon monofilament reel is installed. The reel clamping assembly 6 and the lateral support rod assembly 5 are driven synchronously, and multiple groups of reels are installed at the same time. The monofilament on the nylon monofilament reel passes through the guide bracket 7 and is wound around the twisting reel. As the twisting reel rotates, the nylon monofilament is twisted.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
