Description

Technical Field

[0001] This utility model relates to a yarn coating processing device, and more particularly to a mechanical device that achieves composite yarn winding and coating processing by means of a magnetic coupling that transmits power efficiently without substantial physical contact, belonging to the field of textile machinery technology. Background Technology

[0002] Traditional covered yarn processing machinery requires that, before production, the outer yarn of a large spool is distributed and unwound onto several yarn rods through a winding machine to form small bobbins. The small bobbins are then fitted onto spindles for yarn covering. This traditional production method is time-consuming, labor-intensive, inefficient, energy-intensive, has high operating costs, and is labor-intensive, resulting in poor economic benefits. Currently, there is no covered yarn processing device that can solve the above problems. Utility Model Content

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The covering yarn processing device includes a covering yarn machine frame, and its structural features are: it also includes a high-speed covering yarn motor, a transmission belt, a lower magnetic column, a high-speed spindle, an upper magnetic column, an upper central shaft, a high-speed yarn wrapping bobbin, a covering yarn winding mechanism, a central yarn support roller, a support roller transmission mechanism, a support roller mounting plate, an upper magnetic coupling, a lower magnetic coupling, a reduction motor, and a lower central shaft; the lower central shaft is fixed on the covering yarn machine frame, and the lower central shaft is provided with a yarn passage center hole; the high-speed spindle is mounted on the upper central shaft and the lower central shaft through bearings; the high-speed covering yarn motor is mounted on the covering yarn machine frame and connected to the high-speed spindle through a transmission belt; the upper central shaft is fixed to the inner cavity of the high-speed spindle through bearings, and the support roller mounting plate is fixed to the top of the upper central shaft; the lower magnetic column is fixed on the covering yarn machine frame, and the upper magnetic coupling is also provided with a transmission belt; the lower magnetic coupling is fixed to the upper central shaft, and the lower ... The magnetic column is fixed to the bottom of the roller mounting plate. The upper magnetic column is located directly above the lower magnetic column, and the upper and lower magnetic columns cooperate with each other. There is a space gap between the upper and lower magnetic columns to allow the high-speed wrapping bobbin to pass smoothly during rotation. The bottom of the high-speed wrapping bobbin and the high-speed spindle are fixed. The geared motor is mounted on the frame of the covering yarn machine. The lower magnetic coupling is connected to the geared motor. The upper magnetic coupling is mounted on the roller mounting plate. The upper and lower magnetic couplings are coupled by magnetic force. A space gap is formed between the upper and lower magnetic couplings to allow the high-speed wrapping bobbin to pass smoothly during rotation. The center yarn roller is mounted on the roller mounting plate. The center yarn roller and the upper magnetic coupling are connected by the roller transmission mechanism. The covering yarn winding mechanism is mounted on the frame of the covering yarn machine. The covering yarn winding mechanism cooperates with the high-speed wrapping bobbin.

[0005] Preferably, the idler roller transmission mechanism of this utility model is a gear transmission structure. The power transmission of this idler roller transmission mechanism is achieved by a reduction motor installed on the frame of the covering yarn machine sequentially driving the lower magnetic coupling and the upper magnetic coupling, which are then combined with the gear transmission structure.

[0006] Compared with the prior art, this utility model has the following advantages and effects: simple structure and reasonable design.

Detailed Implementation

[0010] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0011] Example

[0012] See Figure 1The covering yarn processing device in this embodiment includes a high-speed covering yarn motor 2, a covering yarn machine frame 3, a transmission belt 4, a lower magnetic column 5, a high-speed spindle 6, an upper magnetic column 7, an upper central shaft 8, a high-speed covering yarn bobbin 9, a covering yarn winding mechanism 13, a central yarn idler roller 15, an idler roller transmission mechanism 16, an idler roller mounting plate 17, an upper magnetic coupling 18, a lower magnetic coupling 19, a reduction motor 20, and a lower central shaft 21. The idler roller transmission mechanism 16 is a gear transmission structure. The power transmission of the idler roller transmission mechanism 16 is achieved by the reduction motor 20 installed on the covering yarn machine frame 3 sequentially driving the lower magnetic coupling 19 and the upper magnetic coupling 18, combined with the gear transmission structure.

[0013] In this embodiment, the lower central shaft 21 is fixed on the cover yarn machine frame 3, and the lower central shaft 21 is provided with a yarn guide center hole; the high-speed spindle 6 is mounted on the upper central shaft 8 and the lower central shaft 21 through bearings; the high-speed cover yarn motor 2 is mounted on the cover yarn machine frame 3 and is connected to the high-speed spindle 6 through the transmission belt 4, and the high-speed cover yarn motor 2 drives the high-speed spindle 6 to rotate at high speed through the transmission belt 4.

[0014] In this embodiment, the upper central shaft 8 is fixed to the inner cavity of the high-speed spindle 6 by bearings, and the roller mounting plate 17 is fixed to the top of the upper central shaft 8; the lower magnetic column 5 is fixed to the frame 3 of the covering yarn machine, and the upper magnetic column 7 is fixed to the bottom of the roller mounting plate 17. The upper magnetic column 7 is located directly above the lower magnetic column 5, and the upper magnetic column 7 and the lower magnetic column 5 cooperate with each other without substantial physical contact. A spatial gap is formed between the upper magnetic column 7 and the lower magnetic column 5 to allow the high-speed yarn wrapping bobbin 9 to pass smoothly when rotating, so that the outer yarn can rotate horizontally without obstruction under the drive of the high-speed spindle 6. Since the magnetic field has the opposite attraction mechanism, it is ensured that the lower magnetic column 5 and the upper magnetic column 7 will not move relative to each other.

[0015] In this embodiment, the bottom of the high-speed wrapping bobbin 9 and the high-speed spindle 6 are fixed. The outer wrapping yarn on the outer wrapping yarn ball 1 enters from the lower part of the yarn passing center hole of the lower central shaft 21, and then passes horizontally out from the cylindrical surface of the high-speed spindle 6. It then passes through the spatial gap and is guided by the high-speed wrapping bobbin 9 to walk along the outer wrapping yarn path 14, while the center yarn walks along the center yarn path 11. Under the high-speed rotation of the high-speed wrapping bobbin 9, the outer wrapping yarn and the center yarn are wrapped together at the outer wrapping yarn and center yarn covering point 12.

[0016] In this embodiment, the geared motor 20 is mounted on the frame 3 of the covering yarn machine. The lower magnetic coupling 19 is connected to the geared motor 20, and the upper magnetic coupling 18 is mounted on the idler roller mounting plate 17. The upper magnetic coupling 18 and the lower magnetic coupling 19 are coupled by magnetic force, and a space gap is formed between the upper magnetic coupling 18 and the lower magnetic coupling 19 to allow the high-speed covering bobbin 9 to pass smoothly when rotating. The center yarn idler roller 15 is mounted on the idler roller mounting plate 17. The center yarn idler roller 15 and the upper magnetic coupling 18 are connected by the idler roller transmission mechanism 16. The center yarn bundle 10 is placed on the center yarn idler roller 15. The geared motor 20 transmits power to the center yarn roller 15 via the magnetic coupling of the upper magnetic coupling 18 and the lower magnetic coupling 19 and the roller transmission mechanism 16. The center yarn roller 15 drives the center yarn bundle 10 to rotate, realizing controllable yarn feeding. There is no substantial physical contact between the upper magnetic coupling 18 and the lower magnetic coupling 19. A space gap is formed between them to allow the high-speed wrapping bobbin 9 to pass smoothly when rotating. Under normal circumstances, the space gap between the upper magnetic coupling 18 and the lower magnetic coupling 19 is at the same horizontal level as the space gap between the lower magnetic column 5 and the upper magnetic column 7.

[0017] In this embodiment, the covering yarn winding mechanism 13 is installed on the frame 3 of the covering yarn machine. The covering yarn winding mechanism 13 and the high-speed covering yarn bobbin 9 work together to wind and shape the finished yarn after covering.

[0018] The covering yarn processing device in this embodiment can achieve single-spindle single-control. By controlling the rotation speed of the covering yarn winding mechanism 13 and the center yarn support roller 15, the precise adjustment and control of the center yarn roller ratio can be achieved. The large-bore outer covering yarn raw material is directly placed on the material rack and guided by the high-speed spindle 6 and the high-speed covering yarn bobbin 9 to achieve effective covering with the center yarn, without the need to disperse the yarn into multiple yarn rods to make small yarn bobbins for preparation. The upper central shaft 8 and the support roller mounting plate 17 are rigidly connected by a connector, and then attracted by the magnetic fields of the lower magnetic column 5 and the upper magnetic column 7 to ensure that the support roller mounting plate 17 and the covering yarn machine frame 3 remain in a state of no relative movement.

[0019] The processing method of the covered yarn processing device in this embodiment is as follows: The outer yarn bundle 1 of the large roll is directly placed at the designated position of the frame 3 of the covered yarn machine without rewinding. The outer yarn rotates with the high-speed wrapping drum 9 under the drive of the high-speed spindle 6. Through the action of the high-speed wrapping drum 9, it is combined with the center yarn in the vertical direction to form the desired covered yarn. The steps of this processing method are as follows: (1) Preparation stage: Place the outer yarn bundle 1 of the large spool directly in the designated area of ​​the covering yarn machine frame 3. Use a yarn threading tool to guide the outer yarn vertically upward from the inlet of the large spool through the lower central shaft 21, then horizontally through the gap from the side of the high-speed spindle 6 through the yarn hole, and then guide the outer yarn to the covering point 12 of the outer yarn and the center yarn through the high-speed covering spool 9. Place the center yarn bundle 10 on the center yarn support roller 15, and pull the center yarn vertically out from the center yarn bundle 10 and guide it to the covering point 12 of the outer yarn and the center yarn. The outer yarn and the center yarn are statically combined manually at the covering point. Input the corresponding parameters according to the roller ratio required for the product to complete the setting.

[0020] (2) Covering stage: Check the covering yarn processing device to ensure that the equipment is in good standby condition. Then turn on the power. The high-speed covering yarn motor 2 drives the high-speed spindle 6 to rotate and pull the outer covering yarn to the center yarn at the covering point 12 of the outer covering yarn and the center yarn. At the same time, the reduction motor 20 drives the center yarn roller 15 through the magnetic coupling (upper magnetic coupling 18, lower magnetic coupling 19) and the roller transmission mechanism 16 to realize the active release of the center yarn. The composite covering yarn is wound into a yarn bobbin under the action of the covering yarn winding mechanism 13. Thus, the entire process of covering the outer covering yarn and the center yarn is completed.

[0021] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model.
