Description

[Technical Field]

[0001] This utility model relates to a yarn guiding device, specifically a tension-adjustable yarn guiding device for a primary and secondary twisting integrated machine, belonging to the field of textile machinery technology. [Background Technology]

[0002] As is well known, the yarn guiding mechanism is an important component of yarn production equipment such as twisting machines and winding machines. It is used to guide the yarn to move radially along the yarn tube and to wind the yarn onto the yarn bobbin.

[0003] Existing yarn guiding mechanisms, as shown in the applicant's earlier utility model patent No. 201420209017.3, use a motor to drive a steel wire wheel by rotating in both directions. The steel wire wheel then drives a steel wire rope, which in turn drives the yarn guide head to reciprocate, thus guiding the yarn. However, when the yarn guide head of the above-mentioned yarn guiding mechanism moves back and forth, it generates uneven tension on the yarn. For example, the yarn tension is different when the yarn guide head is in the middle of the yarn bobbin and when it is at both ends of the yarn bobbin. This results in inconsistent tension of the yarn wound onto the yarn bobbin, thus affecting the quality of the yarn winding.

[0004] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide an innovative tension-adjustable yarn guide device for a primary and secondary twisting machine to overcome the defects in the prior art. [Utility Model Content]

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a tension-adjustable yarn guide device for an integrated primary and secondary twisting machine that is simple in structure, easy to use, and provides uniform yarn tension.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a tension-adjustable yarn guiding device for a primary and secondary twisting machine, used to guide the yarn to move left and right, including a mounting plate, a yarn guiding base plate, a yarn guiding wheel, a yarn guiding motor, a synchronous belt, a yarn guiding head, a guide rail, a slider, a coil spring, and a steel wire rope; wherein, the yarn guiding base plate is fixed to the mounting plate and is horizontally arranged; the yarn guiding wheel is pivotally connected to the yarn guiding base plate; the yarn guiding motor is mounted on the yarn guiding base plate and is connected to and drives one of the yarn guiding wheels; the synchronous belt is sleeved on the yarn guiding wheel and is driven by the yarn guiding wheel; the yarn guiding head is fixed on the synchronous belt and is driven by the synchronous belt to move back and forth left and right; the guide rail is mounted on one side of the yarn guiding base plate; the slider cooperates with the guide rail and can move along the guide rail; one end of the steel wire rope is connected to the coil spring, and the other end is connected to the slider; the coil spring is mounted on the mounting plate; it pulls the slider through the steel wire rope.

[0007] The tension-adjustable yarn guide device of the original twisting machine of this utility model is further configured as follows: a yarn guide seat is installed on the yarn guide base plate, and a guide groove is provided on one side of the yarn guide seat; a guide block is provided on one side of the yarn guide head, and the guide block and the guide groove cooperate.

[0008] The tension-adjustable yarn guide device of the original twisting machine of this utility model is further configured such that: a shield is provided on the top of the yarn guide seat, and the shield covers the area above the synchronous belt.

[0009] The tension-adjustable yarn guide device of the original twisting and retwisting machine of this utility model is further configured as follows: a yarn guide wheel is provided on the slider; the yarn is wound onto the yarn guide wheel; and the yarn and the steel wire rope are located on different sides of the yarn guide wheel.

Detailed Implementation Methods

[0021] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 6 As shown, this utility model is a tension adjustable yarn guide device for a primary and secondary twisting machine, which is used to guide the yarn 10 to move left and right. It is assembled from several parts, including mounting plate 1, yarn guide base plate 2, yarn guide wheel 31, yarn guide motor 32, synchronous belt 33, yarn guide head 4, guide rail 5, slider 6, coil spring 7 and steel wire rope 8.

[0022] The mounting plate 1 consists of two parts, left and right. The yarn guide base plate 2 is fixed to the mounting plate 1 and is horizontally positioned.

[0023] The yarn guide wheel 31 is pivotally connected to the yarn guide base plate 2. Specifically, there are two of them, located on the left and right sides of the yarn guide base plate 2.

[0024] The yarn guiding motor 32 is mounted on the yarn guiding base plate 2, and it is connected to and drives one of the yarn guiding wheels 31. The synchronous belt 33 is sleeved on the two yarn guiding wheels 31 and is driven by the yarn guiding wheels 31, thereby realizing the movement of the synchronous belt 33.

[0025] The yarn guide head 4 is fixed on the synchronous belt 33 and is driven by the synchronous belt 33 to move back and forth. The yarn guide head 4 drives the yarn 10 to move left and right, so that the yarn is distributed on the yarn bobbin along the radial direction of the yarn bobbin.

[0026] A yarn guide seat 21 is installed on the yarn guide base plate 2, and a guide groove 22 is provided on one side of the yarn guide seat 21. A guide block 41 is provided on one side of the yarn guide head 4. The guide block 41 cooperates with the guide groove 22 to limit the yarn guide head 4, so that the yarn guide head 4 can only move back and forth along the extension direction of the guide groove 22, and prevent the yarn guide head 4 from deflecting. A shielding cover 23 is provided on the top of the yarn guide seat 21. The shielding cover 23 shields the synchronous belt 33, protects the synchronous belt 33, and prevents lint from accumulating on the synchronous belt 33.

[0027] The guide rail 5 is installed on one side of the yarn guide base plate 2. The slider 6 cooperates with the guide rail 5. One end of the steel wire rope 8 is connected to the coil spring 7, and the other end is connected to the slider 6. The slider 6 is provided with a thread guide wheel 61; the yarn 10 is wound onto the thread guide wheel 61. The yarn 10 and the steel wire rope 8 are located on different sides of the thread guide wheel 61, so that the steel wire rope 8 or the yarn 10 can pull the slider 6 respectively, so that the slider 6 can move along the guide rail 5.

[0028] The coil spring 7 is mounted on the mounting plate 1, and it pulls the slider 6 by winding the steel wire rope 8.

[0029] Furthermore, a cover 9 is installed on one side of the yarn guide plate 2, and a limiting groove 91 is provided on the cover 9; the slider 6 is located in the limiting groove 91 to limit the movement range of the slider 6. The cover 9 and the mounting plate 1 are respectively provided with thread guide nozzles 92 on the side near the coil spring 7; the steel wire rope 8 passes through the thread guide nozzles 92 to achieve deflection, and is located below the cover 9 to protect the moving steel wire rope 8.

[0030] The working principle of the tension adjustable yarn guide device of the original twisting machine of this utility model is as follows: the yarn guide motor 32 rotates in the forward or reverse direction and drives the yarn guide wheel 31. The yarn guide wheel 31 drives the synchronous belt 33, and the synchronous belt 33 is linked to the yarn guide head 4 on it, so that the yarn guide head 4 moves back and forth, thereby guiding the yarn 10.

[0031] As attached Figure 4 As shown, when the yarn guide head 4 moves to the left, that is, away from the coil spring 7, the yarn guide head 4 drives the yarn 10 to move to the left. If the slider 6 is fixed, the tension of the yarn 10 reaches its maximum when the yarn guide head 4 reaches the far left. This design uses the yarn 10 to drive the slider 6 to move to the left along the guide rail 5. The slider 6 pulls the wire rope 8 to release the coil spring 7, and the elasticity of the coil spring 7 counteracts part of the tension on the yarn 10, thus reducing the tension on the yarn. (See attached diagram) Figure 5 As shown, conversely, when the yarn guide head 4 moves to the right, that is, when it approaches the coil spring 7, the elastic restoring force of the coil spring 7 pulls the slider 6, causing the slider 6 to move to the right along the guide rail 5.

[0032] The above-described specific embodiments are merely preferred embodiments of this invention and are not intended to limit this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
