Description

Technical Field

[0001] The invention relates to the technical field of yarn twisting equipment, and in particular to a central axis lead-in type yarn twisting device. Background Art

[0002] Yarn is one of the most basic raw materials in the textile industry. It is a continuous filament made by combing, drawing, twisting and other processing techniques of natural or synthetic fibers. The quality of yarn directly affects the performance and aesthetics of the final fabric, including its strength, elasticity, wear resistance, moisture absorption and breathability. In textile production, there are many types of yarns. According to the different raw materials, they can be divided into cotton yarn, linen yarn, wool yarn, silk yarn and various chemical fiber yarns; according to the structure of the yarn, they can be divided into single yarn, ply yarn, multifilament yarn and so on. Yarn twisting (also called twisting or doubling) refers to the process of twisting two or more yarns together according to a certain rule to form a new yarn. This process can not only increase the strength of the yarn and improve the durability of the fabric, but also adjust the feel, glossiness and breathability of the fabric by changing the structure of the yarn.

[0003] At present, when twisting two yarns together, the twisting device mainly uses two lead frames as guides for the two yarns, and then the two lead frames are installed on the belt of the driving roller to rotate cyclically, and the two yarns are twisted together when the two lead frames are dislocated and move in the opposite direction. Although this twisting device is simple to operate, it still has the following problems:

[0004] 1. The motor drives the transmission roller to rotate so that the belt moves, and the two yarns are twisted together. However, the motor rotates multiple times for the belt to travel one circle, which puts a heavy load on the motor, shortens the life of the motor, and reduces the efficiency of yarn twisting.

[0005] 2. When the two strands of yarn are transported into the lead frame of the twisting device, there is a lack of guidance, which makes it difficult to control the angle of the yarn passing through the lead frame, making it difficult to ensure the stability and accuracy of the twisted wire.

[0006] In summary, there is a need for a twisting device that can efficiently and stably twist yarns. Summary of the invention

The air inlet end of the filter 64 is connected to the inside of the cavity.

[0068] When the outer retaining ring 62 and the inner retaining ring 533 are used to transport the yarn, the dust and residual thread on the surface of the yarn are removed by the filter 64. At the same time, the first cutter 535 is used to cut into the cutting groove 621 to cut the yarn, and the residual thread is immediately cleaned up. The cleaning operation is efficient and convenient.

[0071] When the hollow motor 71 is used to twist the yarn, the hollow motor 71 swings slightly to reduce the impact of the twisting and conveying. At the same time, the first roller 279 is rolled and fitted, and the first spring 277 makes the first roller 279 swing elastically to buffer the swing of the hollow motor 71, thereby ensuring the stability of the yarn conveying and twisting.

[0073] When the twisted yarn is stopped, the first pneumatic rod 42 can be started to push the first push block 434, so that the stop plate 43 is extended to stop the lead frame 73, and the slider 431 moves elastically inside the positioning box 41 during the stop. At the same time, the positioning box 41 uses the third spring 45 to make the whole elastically rise and fall to buffer the collision and ensure the stability of the stopped lead frame 73.

[0074] The working principle and use process of the present invention:

[0075] Press first Figure 1-Figure 10The two winding reels 524 with the yarn wound on them are respectively placed on the two plug posts 523, the yarn is turned to the pulley 522 and inserted into the synchronous gear plate 521, and then the two strands of yarn are passed between the outer retaining ring 62 and the inner retaining ring 533, and once again passed through the two lead frames 73, the hollow motor 71, the outlet block 74, the second fixed seat 75 and the second cutter 8, and then the first motor 233 is started to drive the gear plate 234 to descend, The main cover plate 21 is fitted and sealed on the support plate 27, the fixed frame 51, the circular plate and the top surface of the baffle plate 3, and the side sealing plate 24 is fitted on the side wall of the fixed frame 51. The side sealing plate 24 is lowered so that the ends of the two plug posts 523 pass through the positioning grooves 252 and enter the through holes 251 of the side sealing plate 24, so that the plug posts 523 are fitted with the inner wall of the through holes 251. The side sealing plate 24 stops the winding drum 524 on the plug posts 523, so that the yarn can be stably transported.

[0076] Then, the hollow motor 71 and the second motor 56 are started, and the hollow motor 71 drives the central control rotor to rotate, so that the yarns on the two lead frames 73 are twisted together, and the twisted yarns pass through the second cutter 8 and are wound up and collected by the external winding device. At the same time, the first gear 232 and the second gear 54 cooperate to drive the synchronous toothed disc 521 to rotate, and the synchronous toothed disc 521 and the lead frame 73 rotate synchronously to ensure that the two strands of yarn are stably transported to the hollow rotor 712 for twisting. At this time, the twisting situation can be observed through the transparent window plate 22, and the remaining situation of the wound yarn can be observed through the transparent protective cover 25.

[0077] During the twisting process, the vacuum cleaner 273, the fan 9 and the filter 64 are started. The vacuum cleaner 273 removes dust and residual wire attached to the passing yarn through the air holes on the outer retaining ring 62. At the same time, the lead frame 73 rotates the twisted yarn, and the fan 9 blows the impurities generated by the twisting upward, so that the impurities are adsorbed by the adsorption film 553 on the top. As the second gear 54 drives the rotating shaft 551 to rotate, the adsorption film 553 moves in a circular motion, and when it moves to the position of the scraper 272, the adsorbed impurities are scraped into the inside of the collection box 271 and are sucked away by the vacuum cleaner 273, thereby ensuring that the yarn twisting is in a clean environment;

[0078] After the yarn twisting and winding is completed, it can be directly cut off by the second cutter 8. When the yarn twisting needs to be directly interrupted, first start the first pneumatic rod 42, extend the stop plate 43 to stop the lead frame 73 from rotating, and start the second pneumatic rod 539 to push the fixed cylinder 538, and extend the two first cutters 535 to the inside of the cutting groove 621 of the outer stop ring 62 to cut the yarn before twisting, and at the same time remove the residual yarn produced by the cutting. Finally, just lift and open the main cover 21 for inspection, replace the winding reel 524, and continue the yarn twisting work.
