Description

Technical Field

[0001] This utility model relates to the field of twisting machine technology, specifically to an electronic yarn guiding device for a twisting machine. Background Technology

[0002] A doubling machine consists of multiple adjacent spindles of the same type. Each spindle includes two sets of doubling devices, which are mainly composed of spindles, traverse yarn guiding devices and winding mechanisms. The twisted yarn is wound onto the take-up roller at a certain speed by friction drive of friction rollers. When the yarn is wound, a yarn guiding device is needed to arrange the yarn so that the yarn is evenly wound on the outside of the take-up roller.

[0003] According to announcement number CN 110453325 B, a yarn guiding device for a doubling machine solves the problem that the tension of existing yarn guiding devices cannot be adjusted, and the textile yarn is prone to splitting and breaking, which seriously affects the work quality: by using vertical adjustment components and horizontal adjustment components to drive the position of the yarn guiding components in the X-axis and Z-axis directions, the adjustment is simple and convenient, keeping the textile yarn in a taut state and avoiding the splitting of the textile yarn.

[0004] This device uses a cylinder to drive a drive rod in the X-axis direction, causing the drive disc to move along with the drive rod in the X-axis direction. Transmission block A cooperates with the drive groove, causing the drive rod to move in the Z-axis direction, thus adjusting the position of the yarn guide assembly in the Z-axis direction. A motor drives the main shaft to rotate, and the pulley rotates with the main shaft. Friction between the cable and the pulley causes the cable to move, thus adjusting the position of the yarn guide assembly in the X-axis direction. The yarn guide assembly improves product quality, and the springs act as a buffer, reducing tension fluctuations and minimizing yarn breakage. However, the reciprocating distance of this device is not adjustable, limiting its application to only one type of take-up roller, significantly restricting its range of uses. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronic yarn guiding device for a doubling machine, comprising a mounting box, wherein an adjustment mechanism is provided on the front side of the mounting box and a spring-back mechanism is provided on the inner wall of the mounting box;

[0007] The adjustment mechanism includes a fixed base, which is fixedly connected to the front of the mounting box. A T-slot is provided on the front of the fixed base, and a T-block is slidably connected to the T-slot.

A fixing frame is fixedly connected to the front of the fixing member, and a rotating shaft is rotatably connected to the left and right sides of the fixing frame. A tensioning wheel is fixedly connected to the surface of the rotating shaft, and a rotating rod is rotatably connected to the top of the fixing member.

A motor is fixedly connected to the top of the mounting box near the left side of the front, and an eccentric wheel is fixedly connected to the surface of the motor output shaft.

[0008] Preferably, the mounting box has a groove on the left side of the front side that matches the slide plate, and the surface of the slide plate passes through and slides left and right in the groove.

[0009] Preferably, the top of the mounting box has a hole on the left side near the front, which matches the motor output shaft, and the surface of the motor output shaft passes through and is rotatably connected to the hole.

[0010] Preferably, the disk and the eccentric wheel are at the same level.

[0011] Preferably, the rebound mechanism includes a second fixed plate, which is fixedly connected to the left side of the inner wall of the mounting box near the front. A third fixed plate is fixedly connected to the right end of the front of the second fixed plate. Guide rods are symmetrically fixedly connected to the left side of the third fixed plate, and a spring is sleeved on the surface of the guide rod between the third fixed plate and the slide plate.

[0014] Compared with the prior art, the present invention provides an electronic yarn guiding device for a doubling machine, which has the following advantages:

[0015] 1. The electronic yarn guide device for the doubling machine, through the adjustment mechanism, starts the motor to make the eccentric wheel rotate. The rotation of the eccentric wheel hits the disc, causing the disc to move to the left. The disc, through the cooperation of the first fixed plate, drives the slide plate to move to the left, thereby driving the fixed block to move to the left. Moreover, the rotating rod can drive the guide ring to adjust with the movement of the yarn, thereby reducing the friction between the yarn and the guide ring, which is beneficial to the protection of the yarn.

[0016] 2. The electronic yarn guide device for the doubling machine, through the spring mechanism, when the motor is working continuously, drives the eccentric wheel to rotate. When the eccentric wheel hits the disc, it will drive the slide plate to move to the left, thereby stretching the spring. When the eccentric wheel is not in contact with the disc, the slide plate will move to the right by the tension of the spring, thereby driving the fixed block to move to the right, and thus causing the guide ring to swing back and forth.

A T-block 23 is slidably connected to the T-slot 22. A fixed block 24 is fixedly connected to the front of the T-block 23.

A rotating shaft 27 is rotatably connected to the left and right sides of the fixing frame 26. A tensioning wheel 28 is fixedly connected to the surface of the rotating shaft 27. A rotating rod 29 is rotatably connected to the top of the fixing member 25. A wire ring 211 is fixedly connected to the top of the rotating rod 29. A sliding plate 212 is fixedly connected to the left side of the fixed block 24. A first fixing plate 213 is fixedly connected to the top of the sliding plate 212. A disc 214 is fixedly connected to the top of the first fixing plate 213. A motor 215 is fixedly connected to the top of the mounting box 1 near the left side of the front.

[0030] The mounting box 1 has a groove on the left side of the front that matches the slide plate 212, and the surface of the slide plate 212 is connected to the groove by sliding left and right.

[0031] The top of the mounting box 1, near the left side of the front, has a hole that matches the output shaft of the motor 215, and the surface of the output shaft of the motor 215 passes through and is rotatably connected to the hole.

[0032] The disc 214 and the eccentric wheel 216 are at the same level.

[0033] Example 2

[0034] Please see Figure 5 Furthermore, based on Example 1, a springback mechanism 3 was obtained.

[0035] The rebound mechanism 3 includes a second fixed plate 31, which is fixedly connected to the left side of the inner wall of the mounting box 1 near the front. A third fixed plate 32 is fixedly connected to the right end of the front of the second fixed plate 31. Guide rods 33 are symmetrically fixedly connected to the left side of the third fixed plate 32. A spring 34 is sleeved on the surface of the guide rod 33 between the third fixed plate 32 and the slide plate 212.

[0036] The third fixing plate 32 is fixedly connected to the left side of the front of the inner wall of the mounting box 1. The left end of the guide rod 33 is fixedly connected to the left side of the inner wall of the mounting box 1.
