Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, specifically to a spinning machine with adjustable tension. Background Technology

[0002] A walking-beam spinning frame is a periodic device that uses reciprocating motion to complete the spinning process. Its core feature is that drafting, twisting, and winding are separated through the horizontal reciprocating movement of the bobbin or spindle frame. This model inherits the technological principles of traditional walking-beam spinning frames, and its drafting zone can reach several meters in length, allowing the fiber to obtain more space for density adjustment during lateral movement. It is especially suitable for processing specialty animal fibers such as cashmere and rabbit hair.

[0003] In existing ring spinning machines, the elastic modulus of the tension wire gradually decreases over time due to factors such as continuous high-frequency vibration of the equipment, high-speed friction of the yarn, and metal fatigue of the wire itself. This causes the initially set preload to gradually loosen, but it is often difficult for operators to detect in time, resulting in a decline in product quality. At the same time, the manual tensioning process is cumbersome and requires machine downtime, affecting the continuity of production. Therefore, a ring spinning machine with easily adjustable tension is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a walking frame spinning machine that facilitates tension adjustment, in order to solve the problems mentioned in the background art, where the tension wire of the existing walking frame spinning machine gradually loosens during long-term operation, but it is difficult for the staff to detect it in time, resulting in a decline in product quality. At the same time, the manual tensioning process is cumbersome, requires machine stoppage and waiting, and affects the continuity of production.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a walking frame spinning machine with adjustable tension, comprising a main body assembly, wherein a tensioning assembly is provided on the top of the main body assembly, and the tensioning assembly comprises a support plate, a fixed shaft, a first connecting rod, a drive motor, a threaded rod, a slider, a pressure sensor, a fixing nut, a threaded sleeve, a steel wire rope, and a second connecting rod;

[0006] The inner wall of the support plate is symmetrically rotatably connected to two fixed shafts. The outer wall of the fixed shafts is fixedly connected to a first connecting rod and a second connecting rod. A drive motor is installed on one side of the first connecting rod. The output shaft of the drive motor is fixedly connected to one end of a threaded rod. A slider is threadedly connected to the outer wall of the threaded rod.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0016] 1. This utility model uses a pressure sensor to detect the tension of the wire rope. When the tension decreases, a signal is sent to the spinning machine control system. The control system then automatically adjusts the tension to prevent a decline in product quality.

[0017] 2. This utility model uses a drive motor to rotate the threaded rod, which moves the slider and tightens the wire rope, thereby increasing the tension.

[0027] Example

[0028] In the existing technology, the tension wire of the existing walking frame spinning machine gradually loosens during long-term operation, but it is difficult for the staff to detect it in time, resulting in a decline in product quality. At the same time, the manual tensioning process is cumbersome and requires machine downtime, which affects the continuity of production.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a walking frame spinning machine with easy tension adjustment, including a main body assembly 10, a tensioning assembly 20 is provided on the top of the main body assembly 10, the tensioning assembly 20 includes a support plate 21, a fixed shaft 22, a first connecting rod 23, a drive motor 24, a threaded rod 25, a slider 26, a pressure sensor 27, a fixing nut 28, a threaded sleeve 29, a steel wire rope 210 and a second connecting rod 211;

[0030] The inner wall of the support plate 21 is symmetrically connected to two fixed shafts 22. The outer wall of the fixed shafts 22 is fixedly connected to a first connecting rod 23 and a second connecting rod 211. A drive motor 24 is installed on one side of the first connecting rod 23. The output shaft of the drive motor 24 is fixedly connected to one end of a threaded rod 25. A slider 26 is threadedly connected to the outer wall of the threaded rod 25. A through hole is opened inside the slider 26. A pressure sensor 27 is installed on one side of the slider 26. A fixing nut 28 is provided on one side of the pressure sensor 27. A threaded sleeve 29 is threadedly connected to the inner wall of the fixing nut 28. A steel wire rope 210 is rotatably connected to the inner wall of the threaded sleeve 29. The pressure sensor 27 and the drive motor 24 are connected to the original control system of the spinning frame. When the control system receives the signal from the pressure sensor 27, it controls the drive motor 24 to work and tension the steel wire rope 210. The diameter of the through hole inside the slider 26 is larger than the outer diameter of the steel wire rope 210 so that the steel wire rope 210 can pass through the slider 26. The slider 26 is fixed by the fixing nut 28 and the threaded sleeve 29. After tensioning, the fixing nut 28 squeezes the pressure sensor 27, and the tension of the steel wire rope 210 is calculated by the pressure.

[0031] In this embodiment, specifically: one end of the wire rope 210 is installed inside the second connecting rod 211, and both ends of the wire rope 210 are fixed by threaded sleeves 29 and fixing nuts 28.

[0032] In this embodiment, specifically: the main component 10 includes a frame 11 and a support base 12;

[0033] The top of the frame 11 is symmetrically and fixedly connected with support bases 12, and the number of support bases 12 can be adjusted according to the production scale.

[0034] In this embodiment, specifically: an electric guide rail 13 is installed on the top of the support base 12. The electric guide rail 13 is driven by a motor. When the electric guide rail 13 is working, it drives the slide table 14 to move. The electric guide rail 13 is a common technical means for spinning machine equipment. Its structure has been disclosed and will not be described in detail here.

[0035] In this embodiment, specifically: a slide table 14 is slidably connected to the top of the electric guide rail 13, and when the slide table 14 moves, it drives the roving roll 15 and the guide roller 16 to move.

[0036] In this embodiment, specifically: a roving roll 15 is rotatably connected to the top of the slide table 14, and the roving roll 15 is used to wind up the roving.

[0037] In this embodiment, specifically: a yarn guide roller 16 is installed on the top of the slide table 14, and the yarn guide roller 16 is used to control the direction of the yarn.

[0038] In this embodiment, specifically: the threaded rod 25 is rotatably connected to the inner wall of the first connecting rod 23.

[0039] The working principle or structural principle is as follows: after the wire rope 210 is tensioned, the fixed nut 28 squeezes the pressure sensor 27. The pressure sensor 27 detects the tension of the wire rope 210. When the tension decreases, a signal is sent to the spinning machine control system. The control system calculates the tension of the wire rope 210 based on the pressure. When the tension is insufficient, the control system controls the drive motor 24 to rotate the threaded rod 25, causing the slider 26 to move and tighten the wire rope 210, thereby increasing its tension. The operation is simple and convenient, saving time and eliminating the need to stop the machine to wait, thus avoiding affecting the continuity of production. The tension adjustment operation is automatically completed by the control system to prevent a decline in product quality.
