[0023] It should be noted that the doubling module placed on the workbench 1 in this embodiment is a part of the doubling spindle in the doubling device, most of the flying fluff is charged (positive / negative) due to friction or electrostatic induction, and is easy to float in the air. The electrostatic adsorption rod 3 generates ion cloud through corona discharge to achieve active adsorption of the flying fluff.

[0025] As shown in Figure 2 and Figure 4 , the cleaning device 5 can include a driving assembly 51, a scraper 52, a first lead screw driving part 53, and a push plate 54. The scraper 52 is arranged on the driving assembly 51, the driving assembly 51 is configured to drive the scraper 52 to scrape the flying fluff on the lifting platform 2 and the moving scraper 4, the first lead screw driving part 53 is arranged on the scraper 52, and the push plate 54 is arranged on the first lead screw driving part 53. The push plate 54 is slidingly connected with the upper surface of the lifting platform 2, and the first lead screw driving part 53 is configured to drive the push plate 54 to move along the scraping edge direction of the scraper 52. The scraper 52 includes a first cleaning part 521 and a second cleaning part 522, the first cleaning part 521 is arranged on the upper part of the second cleaning part 522, the first cleaning part 521 is used for scraping the flying fluff on the lower part of the moving scraper 4, and the second cleaning part 522 is used for scraping the flying fluff on the upper part of the lifting platform 2. The push plate 54 is slidingly connected with the surface of the scraper 52.

[0026] It should be noted that the application can also be provided with a recycling bin 9, and the cleaning device 5 is arranged in the recycling bin 9, and the recycling bin 9 is in communication with the cleaning bin 8. The cleaning bin 8 and the recycling bin 9 jointly form a cleaning space, which can also be directly provided by the two-for-one twisting device.

[0027] It can be understood that the driving assembly 51 described in this embodiment can drive the scraper 52 to scrape the flying flocks on the lifting platform 2 and the moving scraper 4, and uniformly push the flying flocks accumulated on the scraper 52 to the target position through the movable push plate 54, avoiding the accumulation of flying flocks.

[0028] In order to clearly illustrate the above embodiment, in an embodiment of the application, as shown in Figure 2 The driving assembly 51 can include: an annular mounting frame 511, a first motor 512, a driving wheel 513, an inner tooth ring 514, and a second screw drive 515, wherein the annular mounting frame 511 can be arranged in the recycling bin 9, the first motor 512 is in sliding connection with the annular mounting frame 511, the driving wheel 513 is arranged at the driving end of the first motor 512, the driving wheel 513 is in meshing with the inner tooth ring 514, the second screw drive 515 is arranged on the first motor 512, and the scraper 52 is arranged on the second screw drive 515. A limiting sliding groove 6 is formed on the annular mounting frame 511, a limiting sliding block 7 is arranged on the first motor 512, and the limiting sliding groove 6 and the limiting sliding block 7 are in sliding connection. It should be noted that the cross section of the limiting sliding groove 6 is T-shaped, and the cross section of the limiting sliding block 7 is also T-shaped.

[0029] Specifically, the two-for-one twisting module is stably installed on the workbench 1, and the chemical fiber passes through the cleaning bin 8 through the wire outlet and is connected to the winding mechanism. When the two-for-one twisting module operates at high speed, the friction between the spindle and the two-for-one twisting disc and the aerodynamic effect will generate a large amount of flying flocks. At this time, the high-voltage electrostatic adsorption rod 3 (which can be arranged as a negative polarity discharge electrode) uniformly distributed in the cleaning bin 8 ionizes the air through corona discharge, and the generated positive ions make the flying flocks carry positive charges after contacting the flying flocks. The flying flocks with positive charges are directionally adsorbed to the surface of the electrostatic adsorption rod 3 under the action of electric field force. This design can realize efficient capture at the first time of flying flock generation, avoiding the diffusion of flying flocks to the key positions such as the transmission parts and the yarn guide device of the two-for-one twisting module due to high-speed airflow of the device.

[0030] When the fly floss adsorbed on the surface of the electrostatic adsorption rod 3 reaches the preset threshold, the moving scraper 4 moves vertically towards the lifting platform 2, and a clamping sealing area is formed through the precise fitting of the two. Then, the moving scraper 4 moves downwards to the cleaning device 5 synchronously with the lifting platform 2, and the moving scraper 4 moves away from the lifting platform 2 to expose the space to be cleaned. The second lead screw drive 515 precisely positions the scraper 52 to the gap between the two, and the first motor 512 drives the driving wheel 513 to move in a ring along the inner tooth ring 514, thereby driving the scraper 52 to perform a 360° circumferential cleaning action. Compared with the traditional linear cleaning method, the cleaning blind area is avoided, and the size of the scraper 52 is reduced. After cleaning, the first lead screw drive 53 controls the push plate 54 to direct the fly floss on the lifting platform 2 away from the workbench 1 and into the recycling bin 9. Through the reciprocating motion of the push plate 54, uniform collection of fly floss is achieved, avoiding the blockage problem caused by the accumulation of fly floss on one side of the bin body in the traditional recycling method, and ensuring the continuous operation of the equipment. Through the closed-loop processing system of "adsorption-collection-cleaning-recycling", not only the automatic cleaning of fly floss in the two-for-one twisting process is realized, but also the number of downtime maintenance and cleaning is reduced, thereby improving the efficiency of two-for-one twisting.

[0031] In one embodiment of the present application, as shown in Figure 2 The lifting platform 2 can include a hydraulic lifting device 21 and a moving platform 22, wherein the hydraulic lifting device 21 is arranged in the recycling bin 9, and the moving platform 22 is arranged at the driving end of the hydraulic lifting device 21. A through slot is formed in the central part of the moving platform 22, and the workbench 1 is slidably connected with the through slot.

A plurality of through holes are formed in the cleaning scraper 42, and the plurality of through holes correspond one-to-one with the plurality of electrostatic adsorption rods 3.

The third lead screw drive 41 controls the vertical movement of the cleaning scraper 42, and the vertically moving cleaning scraper 42 can scrape off the fly floss adsorbed on the surface of the electrostatic adsorption rod 3.

[0033] The first screw driving part 53 comprises a driving bin 531, a second motor 532, a ball screw 533, a ball slider 534 and a connecting piece 535, wherein the second motor 532 is arranged in the driving bin 531, the ball screw 533 is arranged at a driving end of the second motor 532, the ball slider 534 is arranged on the ball screw 533, and the connecting piece 535 is arranged on the ball slider 534.
