Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, specifically to a yarn guiding structure for preventing deformation of a spinning machine and a spinning machine. Background Technology

[0002] In the modern textile industry, rotor spinning machines occupy an important position in the spinning field due to their unique advantages. The yarn delivery process is crucial, directly affecting the quality and efficiency of spinning. Yarn delivery in rotor spinning machines is mainly accomplished by the collaborative operation of the guide rollers and guide slip rollers in the guide mechanism. Under normal operating conditions, the pressure springs function, applying stable working pressure to the guide rollers on the guide rollers. The two rollers tightly clamp the yarn, continuously propelling it according to precise process requirements, ensuring the stable operation of the spinning process.

[0003] However, the working characteristics of the yarn guide roller present significant challenges under different operating conditions. When the yarn guide roller is rotating, the instantaneous deformation of the rubber surface caused by pressure can recover quickly, which is crucial for maintaining good yarn clamping and conveying performance during normal operation. However, once the equipment enters a prolonged shutdown phase, the yarn guide roller remains stationary and continuously subjected to pressure, making the recovery of deformation on the rubber surface extremely difficult. This unrecoverable deformation can lead to dents or other deformations on the surface of the yarn guide roller, causing the clamping of the yarn by the yarn guide roller and the yarn guide roller to become uneven and unstable after restarting. This severely affects yarn conveying, causing yarn conveying to fail normally, greatly reducing production efficiency, and may even lead to product quality problems such as uneven yarn thickness and increased breakage rate.

[0004] Currently, several solutions exist in the market to address the problem of yarn guide roller deformation under pressure. One method involves using a separate pad for lifting. This method is relatively simple; by placing a pad under the support arm, the roller is lifted when the equipment is stopped, thus avoiding continuous pressure and reducing deformation. However, this method has a significant drawback: the pad is small and easily lost due to operator negligence in actual production environments. If the pad is missing, the yarn guide roller will still deform under pressure when the machine is stopped, affecting subsequent production. Another method is to use hooks to lift the yarn guide roller. This method uses hooks to suspend the roller when the machine is stopped, preventing it from being compressed. However, due to significant differences in structural design and spatial layout among different machine models, this method is greatly limited in practical application, as it is not compatible with many models and is difficult to widely promote and use.

[0005] In summary, the deformation of the yarn guide roller during shutdown in rotor spinning machines has become a key factor restricting the continuity of spinning production and the improvement of product quality. Existing solutions all have their limitations and cannot effectively meet actual production needs. There is an urgent need for an innovative, adaptable, and reliable technical solution to address the deformation of the yarn guide roller and ensure stable and efficient yarn delivery in rotor spinning machines.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example 1

[0027] See Figure 1 and Figure 2As shown, this embodiment provides a yarn guiding structure for a spinning machine to prevent deformation, comprising: a yarn guiding assembly 100, which includes a yarn guiding roller 120 and a mounting base 130, the yarn guiding roller 120 being rotatably connected to the mounting base 130; and a pressure assembly 200, which includes a roller 210, a support arm 220, a pressure member 240, and an adjusting mechanism 230, the middle part of the support arm 220 being rotatably connected to the mounting base 130, the pressure member 240 being disposed at one end of the support arm 220 and located between the support arm 220 and the mounting base 130, and the other end of the support arm 220 being provided with an adjusting groove, a first positioning hole 223, and a second positioning hole 224, and being rotatably connected to the... The roller 210 has an adjustment groove recessed downward from the upper surface of the support arm 220. The first positioning hole 223 and the second positioning hole 224 are located in the same horizontal plane, surrounding the side wall of the adjustment groove and communicating with it. The adjustment mechanism 230 includes a knob 231 and a positioning ball 232. Part of the knob 231 is rotatably inserted into the adjustment groove and connected to the positioning ball 232. One side of the knob 231 has an abutment surface 2313 that can abut against the mounting base 130. The positioning ball 232 can be embedded in the first positioning hole 223 or the second positioning hole 224 to adjust the roller 210 to move closer to / away from the yarn feeding roller 120.

[0028] The anti-deformation yarn feeding structure of the spinning machine described in this embodiment innovatively employs an adjustment mechanism 230 to adjust the relative position of the guide roller 210 and the yarn feeding roller 120. In operation, this allows the yarn to be driven through the pressurized contact between the yarn feeding roller 120 and the guide roller 210. In shutdown mode, the guide roller 210 is positioned away from the yarn feeding roller 120, thus preventing irreversible deformation of the guide roller 210 under prolonged pressurization. This improves the service life of the guide roller 210 and stabilizes yarn transmission. Compared to conventional spinning technologies, this application offers advantages such as high flexibility, ease of adjustment, wide applicability, improved service life, and enhanced yarn transmission quality, making it a promising technology for the industry.

[0029] In this embodiment, the yarn feeding assembly 100 provides driving force for yarn transmission and also includes a rotary driver 110. The rotary driver 110 is disposed inside the mounting base 130, and its working end is connected to the yarn feeding roller 120. The mounting base 130 includes a housing 131 and an extension block 132. The yarn feeding roller 120 is connected to the housing 131, and the extension block 132 is disposed on the side wall of the housing 131 and protrudes horizontally toward the pressure assembly 200. The support arm 220 is rotatably connected to the extension block 132 at its middle. Specifically, in this embodiment, the mounting base 130 provides a mounting and connecting platform for the yarn feeding roller 120, the rotary driver 110, and the pressure assembly 200. The rotary driver 110 drives the yarn feeding roller 120 to rotate around its central axis, and the yarn feeding roller 120 directly contacts the yarn being transported. Specifically, the rotary driver 110 in this embodiment is preferably a rotary motor. In different embodiments, it can also be configured as other structures with rotary driving effect. This utility model does not impose specific limitations on this.

[0030] See Figure 3 As shown, in this embodiment, the pressure member 240, the roller 210, and the support arm 220 together form a lever structure. The pressure member 240 is preferably a compression spring, which is always in a compressed state to apply lateral pressure to the roller 210 via the support arm 220. During yarn feeding, the roller 210 is pressurized relative to the yarn feeding roller 120 under the action of the pressure member 240, thereby achieving yarn transmission. Specifically, the support arm 220 includes a body 221 and a connecting shaft 222. The connecting shaft 222 is located in the middle of the body 221 and passes through and connects the body 221 and the extension block 132, thereby realizing the rotational connection between the support arm 220 and the mounting base 130. It should be noted that the surface of the roller 210 is configured with an elastic material that can deform. Therefore, during its rolling process, the part in contact with the yarn guide roller 120 will deform in a short time and rebound quickly, thereby ensuring the stability of the yarn transmission process. However, when the machine is stopped, the roller 210 is still pressed against the yarn guide roller 120 under the action of the pressure component 240, and it is difficult for it to recover its deformation in a short time. Therefore, there is a risk of deformation of the roller 210. Even if the roller 210 can slowly rebound after disengaging from the yarn guide roller 120, it is difficult to restore a stable transmission state in a short time after restarting the machine.

[0031] Based on this, this application designs an adjustment mechanism 230 that cooperates with the support arm 220 to adjust the position of the roller 210. Specifically, the support arm 220 in this embodiment is provided with an adjustment groove, and the extension directions of the first positioning hole 223 and the second positioning hole 224 are perpendicular to each other. The first positioning hole 223 is located at the end of the support arm 220, and the second positioning hole 224 is located towards the yarn feeding assembly 100. In different embodiments, the number and specific location of the positioning holes can be adaptively adjusted according to actual usage requirements, and this utility model does not make specific settings in this regard.

[0032] See Figure 4 and Figure 5 As shown, the knob 231 includes a plug-in portion 2311 and an operating portion 2312. The plug-in portion 2311 passes through the adjustment groove, the positioning ball 232 is connected to the plug-in portion 2311, one end of the operating portion 2312 is vertically connected to the plug-in portion 2311, and the other end extends along the top surface of the support arm 220. The abutment surface 2313 is provided at the free end of the operating portion 2312. Based on this, the knob 231 can drive the positioning ball 232 installed on it to move between the first positioning hole 223 or the second positioning hole 224. When the positioning ball 232 is embedded in the first positioning hole 223, the knob 231 can avoid the mounting seat 130, and the roller 210 presses against the yarn feeding roller under the driving action of the pressure member 240. When the positioning ball 232 is embedded in the second positioning hole 224, the abutting surface 2313 of the knob 231 abuts against the mounting seat 130, so as to further press the pressure member 240 through the support arm 220, thereby making the roller 210 move away from the yarn feeding roller in the horizontal direction. Based on this, in the stopped state, the roller 210 is set relatively independently from the yarn feeding roller, so the deformation damage caused by long-term pressure to the roller 210 can be fundamentally avoided.

[0033] Furthermore, in this embodiment, the insertion part 2311 is provided with a receiving groove, which is recessed inward from the side wall of the insertion part 2311. One side of the positioning ball 232 is connected to the receiving groove, and the other side protrudes from the insertion part 2311 in the horizontal direction. Correspondingly, the positioning ball 232 includes a ball shell 2321, a spring 2322, and a steel ball 2323. The ball shell 2321 is disposed in the receiving groove, and the spring 2322 is embedded inside the ball shell 2321, with one end connected to the ball shell 2321 and the other end connected to the steel ball 2323. When the positioning ball 232 moves along the inner surface of the receiving groove, the spring 2322 is always in a compressed state. Thus, when it rotates to the first positioning hole 223 or the second positioning hole 224, the spring 2322 can automatically push the steel ball 2323 through and engage it in the corresponding positioning hole. When driving is required, the operator only needs to apply a tangential force in the direction of rotation to the knob 231.

[0034] Furthermore, to further improve the mobility of the pressure assembly 200, the pressure assembly 200 in this embodiment also includes a gripping rod 250. The gripping rod 250 is connected to the end of the support arm 220 that is provided with the adjustment mechanism 230, and extends in a direction away from the pressure member 240, so as to provide the operator with another way to adjust the gap between the roller 210 and the yarn feeding roller 120, thereby realizing the dual function of adjusting the roller 210. Example 2

[0035] This embodiment provides a spinning machine, which includes the anti-deformation yarn guiding structure of the spinning machine described in Embodiment 1.

[0036] In summary, the anti-deformation yarn guiding structure and spinning machine described in this utility model innovatively employ an adjustment mechanism 230 to adjust the relative position of the guide roller 210 and the yarn guiding roller 120. This allows the yarn to be driven through pressurized contact between the yarn guiding roller 120 and the guide roller 210 during operation, while simultaneously allowing the guide roller 210 to move away from the yarn guiding roller 120 during shutdown. This prevents the guide roller 210 from undergoing irreversible deformation under prolonged pressurization, thereby improving its service life and stabilizing yarn transmission. Compared to current conventional spinning technologies, this application offers advantages such as high flexibility, ease of adjustment, wide applicability, improved service life, and enhanced yarn transmission quality, making it a promising technology for the industry.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
