Description

Technical Field

[0001] The utility model relates to the technical field of a silk doubling machine, and more particularly to a reciprocating yarn guiding device on a silk doubling machine. Background Art

[0002] At present, the silk untwisted winding machine is a textile processing equipment that combines multiple silks into a single bundle and winds the single bundle of silk onto a silk drum. Therefore, the silk drum is the carrier of the silk. When the silk on the silk drum is fully rolled, it needs to be replaced. The silk drum on the current traditional winding machine is generally installed on a vertical winding spindle. However, when the untwisted single bundle of silk is wound on the winding spindle silk drum, the silk threads in the single bundle of silk will separate on the silk drum; and it will also come into contact with the silk drum or the winding spindle, which will cause wear of the silk and affect the quality of the silk. Therefore, a new silk winding device needs to be replaced. Therefore, some people have proposed to design the silk drum to rotate horizontally, so that the problem of silk separation and wear will not occur. However, when the horizontally rotating silk drum rewinds the combined silk, if there is no wire guide mechanism that can move horizontally, the wound silk threads will only be in a section of the silk drum, and will not cover the entire silk drum, so a corresponding wire guide mechanism needs to be designed.

[0020] Example: See Figures 1 to 4 As shown, a reciprocating yarn guiding device on a silk doubling machine includes a doubling frame 1, an electric control cabinet 2 is fixedly connected to the left side of the doubling frame 1, and wire guide frames 4 are respectively provided on the front and rear sides of the doubling frame 1. The wire guide frames 4 include a transverse pulling guide rod 41, and a plurality of wire guide seats 42 are fixedly connected to the pulling guide rod 41. The wire guide seats 42 are linearly and evenly distributed on the pulling guide rod 41. The left end of the pulling guide rod 41 is connected to an actuator 3. The actuator 3 is arranged on the top of the electric control cabinet 2 and drives the wire guide frame 4 to perform reciprocating transverse motion between the front and rear sides of the doubling frame 1.

[0021] The actuator 3 includes guide rails 31 respectively fixed to the front and rear sides of the electric control cabinet 2, and two groups of sliders 32 are inserted into the guide rails 31. A horizontal connecting shaft 33 is inserted and fixed on the slider 32, and the right end of the connecting shaft 33 is fixed to the pulling guide rod 41; a rectangular ring-shaped transmission belt 34 is provided between the guide rails 31, and guide wheels 36 are respectively wrapped around the four corners of the transmission belt 34, and the guide wheel 36 is pivotally connected to the electric control cabinet 2. The front and rear sides of the transmission belt 34 are respectively clamped and fixed on the slider 32, and an extension belt concave to the left is formed on the right side. A drive pulley 37 is wrapped around the extension belt, and the drive pulley 37 is fixed on the rotating shaft of the servo motor through a sleeve, and the servo motor is fixed in the electric control cabinet 2.

[0022] The longitudinal section of the pulling guide rod 41 is rectangular, and a number of nylon guide blocks 6 are inserted into the pulling guide rod 41. The front and rear sides of the wire drawing frame 1 are respectively fixed with a number of mounting support plates 5. The nylon guide blocks 6 are inserted and fixed on the upper part of the mounting support plates 5, and the wire guide frame 4 is supported by the mounting support plates 5.

[0023] A connecting head 331 is formed at the left end of the connecting shaft 33, and a rectangular plug rod is formed on the right end surface of the connecting head 331. A slot is formed at the left end of the pulling guide rod 41. The plug rod of the connecting shaft 33 is inserted into the slot of the pulling guide rod 41 and is screwed with a number of positioning bolts 38. The positioning bolts 38 are inserted on the pulling guide rod 41, which is the specific connection structure between the pulling guide rod 41 and the connecting shaft 33.

[0024] The diameter of the driving pulley 37 is larger than that of the guide wheel 36. The driving pulley 37 is a synchronous pulley, and the transmission belt 34 is a synchronous belt to prevent slipping.

[0025] The guide wire seat 42 comprises a rectangular positioning seat, a protrusion is formed in the middle of the end face of the positioning seat on the side away from the doubling frame 1, and arc-shaped elastic guide wire rings 421 are respectively inserted and fixed on the positioning seat on both sides of the protrusion, and the ends of the elastic guide wire rings 421 are against the side walls of the positioning seat;

[0026] There is a gap between the elastic wire guide ring 421 and the protrusion. When threading the wire, the elastic wire guide ring 421 can be pressed to move toward the protrusion, and the end of the elastic wire guide ring 421 will be separated from the positioning seat, and the silk can enter the elastic wire guide ring 421 from the gap. The presence of the protrusion can constrain and limit the elastic wire guide ring 421 to prevent the elastic wire guide ring 421 from being deformed due to excessive pressing force.

[0027] The slider 32 includes an inverted T-shaped seat block, which is formed with a socket 321 opposite to the connecting shaft 33. A boss 322 is formed on the end face of the slider 32 close to the middle of the electric control cabinet 2, and a slot 323 is formed on the boss 322. A clamping block 35 is provided at the opening of the slot 323, and the clamping block 35 is screwed to the boss 322; the transmission belt 34 is inserted into the slot 323 and clamped and fixed between the boss 322 and the clamping block 35; it is convenient for installation, connection, disassembly and maintenance.

[0028] A rectangular slot 324 is formed on the lower inner wall of the insertion hole 321 in the slider 32, which passes through the lower end surface of the boss 322. An L-shaped pressing block 39 is inserted into the rectangular slot 324. The lower end of the pressing block 39 extends out of the rectangular slot 324 and is located on one side of the slider 32. A vertical adjusting bolt 310 is screwed onto the pressing block 39, and the adjusting bolt 310 is pivotally connected to the slider 32. Figure 5 As shown, the adjusting bolt 310 is pivotally connected to the slider 32 via a nut. The adjusting bolt 310 adopts a hexagon socket bolt. By rotating the adjusting bolt 310, the pressing block 39 can be moved up and down. When the pressing block 39 moves upward to press the connecting shaft 33, the connecting shaft 33 and the slider 32 are fixedly connected, and the lower end of the pressing block 39 will be separated from the guide rail 31.

[0029] When the pressure block 39 moves downward, it can press on the guide rail 31, and its connecting shaft 33 is separated from the pressure block 39, so that the slider 32 is fixed on the guide rail 31. At the same time, a threaded through hole can be opened on the slider 32, and one slider 32 is fixed to the guide rail 31, and the other slider 32 is fixed to the connecting shaft 33. A horizontal fine-tuning bolt is screwed into the threaded through hole of one of the sliders 32. The position of the connecting shaft 33 can be fine-tuned by the fine-tuning bolt, and then the position of the guide wire seat 42 on the guide wire rack 4 can be fine-tuned.

[0030] Working principle: This structure is a reciprocating yarn guide device on a silk doubling machine. Figure 4 As shown, the wire drawing machine is provided with two sets of wire guide racks 4 on the front and rear sides, and the wire guide racks 4 are matched with two sets of wire drums arranged in a row, and the wire guide racks 4 are provided with wire guide seats 4 corresponding to the wire drums one by one;

During operation, the servo motor controls the positive and negative alternating rotation of the drive pulley 37; thereby, the wire guide seat 4 can be made to move back and forth laterally at the wire tube to realize the yarn guiding function; its structure is simple and easy to operate.

[0032] The embodiments are intended to illustrate the present invention and are not intended to limit the present invention. Any person skilled in the art may modify the embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be as set forth in the claims of the present invention.
