Description

Technical Field

[0001] This invention belongs to the field of spinning machine technology, specifically relating to a dynamic compensation device and control method for the winding tension of a spinning machine. Background Technology

[0002] The dynamic tension compensation device for spinning machines is a closed-loop control device used to stabilize the tension in real time during yarn winding. It uses a tension sensor to detect changes in yarn tension in real time, transmits the signal to the controller, compares it with the set tension, and then quickly adjusts the tension through the tension controller. Thus, it automatically compensates for tension deviations under conditions such as increased roll diameter, speed fluctuations, changes in yarn characteristics, and roll changes, maintaining constant yarn tension, reducing yarn breakage, fuzz, and uneven tension, and improving the quality of package forming and the performance of subsequent processing.

[0003] In existing dynamic tension compensation devices for spinning machines, the guide wheel typically uses an annular groove machined on its rim to guide the yarn. However, under conditions of high-speed winding, yarn splicing, sudden tension changes, or defects such as yarn fuzz or knots, the yarn may jump out of the guide wheel groove and deviate from the predetermined running path due to irregular jumping caused by high-speed centrifugal force, tension fluctuations, and its own defects. This not only leads to tension control failure and significant fluctuations in winding tension, but also significantly increases the yarn breakage rate due to abnormal friction and collision between the yarn and other parts of the equipment. It can even cause the yarn to become entangled in moving parts such as bearings and gears, exacerbating equipment wear, increasing maintenance costs, and downtime. Existing methods that only deepen the groove or increase the wheel diameter have limited effectiveness and cannot fundamentally solve the problem of yarn jumping out of the groove under high-speed and high-tension conditions. Therefore, there is an urgent need for a simple and reliable anti-detachment structure to ensure that the yarn always runs stably in the predetermined path under various complex conditions. Summary of the Invention

[0004] The purpose of this invention is to provide a dynamic compensation device and control method for the winding tension of a spinning machine, so as to solve the problem mentioned in the background art that existing yarns are prone to detach from the guide wheel.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dynamic compensation device for winding tension of a spinning machine, comprising...

[0006] Mounting plate;

[0007] Guide components are rotatably mounted on the surface of the mounting plate;

[0008] The surface of the mounting plate is provided with a protective component, which consists of a protective component and a functional component.

[0009] The protective component is fitted onto the yarn at one end and mounted on the surface of the mounting plate at the other end; the functional component is mounted on one end of the protective component, and the output end of the functional component reduces radial runout by pressing down the yarn; a detection part is also provided on the functional component.

[0010] Preferably, the protective component is a composite structure consisting of a metal plate and a protective sleeve, wherein the metal plate is mounted on a mounting plate, and the protective sleeve is fitted over the outside of the yarn.

[0011] Preferably, the surface of the metal plate is further provided with a moving groove, and a connecting bolt passing through the moving groove is fixed on the surface of the mounting plate. A locking nut is screwed on the outer surface of the connecting bolt, and the locking nut abuts against the surface of the metal plate.

[0012] Preferably, the functional component is a miniature cylinder installed on the outer wall of the protective sleeve, and a pressure sleeve disposed inside the protective sleeve;

[0013] The top of the pressure sleeve extends horizontally outward and forms an extension, on which the output end of the micro cylinder is mounted.

[0014] Preferably, an mounting plate is also installed on the outside of the protective sleeve, and an infrared sensor is installed on the mounting plate, which is placed outside the miniature cylinder.

[0015] Preferably, the guide member comprises multiple guide wheels and a transmission wheel, wherein the yarn passes through all the guide wheels and the transmission wheel, and the transmission wheel is capable of horizontal movement.

[0016] Preferably, a controller is also installed on the rear surface of the mounting plate, and a transmission structure that drives the transmission wheel to move is installed inside the controller.

[0017] This invention also discloses a method for controlling a dynamic compensation device for winding tension in a spinning machine, comprising a dynamic compensation device, specifically including the following steps:

[0018] Step 1: Pass the yarn through all the guide wheels and transmission wheels on the surface of the mounting plate in sequence according to the preset transmission path. Put the protective sleeve of the protective component on the outside of the yarn. Push the metal plate so that the connecting bolts on the surface of the mounting plate slide in the moving groove of the metal plate. Adjust the position of the metal plate and the protective sleeve so that the axis of the protective sleeve and the yarn are matched. Then tighten the locking nut on the outside of the connecting bolt so that the locking nut is tightly against the surface of the metal plate. This completes the fixing of the metal plate and the mounting plate and achieves precise positioning of the protective component on the surface of the mounting plate.

[0019] Step 2: Set parameters using the controller on the back surface of the mounting plate. First, input the normal tension threshold range for yarn winding. Then, set the warning threshold for the infrared sensor to detect the radial runout of the yarn. At the same time, based on the yarn specifications and processing requirements, preset the output end pushing stroke, pushing force, and reset time parameters of the pressure sleeve of the micro cylinder. This completes the matching of the operating parameters of the controller and each functional component, ensuring the linkage response accuracy of the detection unit and the functional components.

[0020] Step 3: Start the spinning machine to drive the guide wheel and transmission wheel to rotate, which will drive the yarn to be transmitted and wound along the preset path. During this process, the infrared sensor installed on the mounting plate on the outside of the protective cover will continuously detect the radial runout of the yarn in real time and transmit the data to the controller. At the same time, the controller will collect and monitor the winding tension data of the yarn synchronously, so as to realize the dual detection of the yarn running status.

[0021] Step 4: When the infrared sensor detects that the radial runout of the yarn exceeds the preset warning threshold, it immediately transmits the runout over-limit signal to the controller. The controller sends a drive command to the micro cylinder. The output end of the micro cylinder extends outward and pushes the extension at the top of the pressure sleeve, causing the pressure sleeve inside the protective sleeve to press down towards the yarn. Through the contact and fit between the pressure sleeve and the yarn, the radial movement range of the yarn is limited until the infrared sensor detects that the runout of the yarn has returned to within the warning threshold. The controller sends a reset command, and the micro cylinder drives the pressure sleeve to reset to the initial position, releasing the downward pressure limit on the yarn.

[0022] Step 5: The controller continuously compares and analyzes the real-time collected yarn winding tension data with the preset normal tension threshold range. When the tension data exceeds the threshold range and a tension deviation is detected, the controller activates the internal transmission structure. The transmission structure drives the transmission wheel to move horizontally on the mounting plate surface. By changing the position of the transmission wheel, the winding path and stretching length of the yarn are adjusted, thereby precisely adjusting the tension of the yarn and realizing dynamic compensation of the winding tension, so that the winding tension of the yarn is always maintained within the preset normal threshold range.

[0023] Step Six: Throughout the entire winding process of the spinning machine, the infrared sensor continuously monitors the radial runout of the yarn, the micro cylinder and pressure sleeve dynamically suppress the runout, and the controller continuously monitors the winding tension and performs tension compensation on the transmission wheel until the yarn winding process is completed. Then, the spinning machine and controller are turned off, completing the entire dynamic compensation operation for winding tension.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The protective components designed by this invention can effectively prevent yarn from detaching from the guide wheel during high-speed operation, tension fluctuations, and splicing, ensuring that the yarn is always within the preset running path, maintaining stable winding tension, reducing tension abnormalities caused by yarn skipping, lowering the probability of yarn breakage, improving the continuity and stability of the spinning process, enhancing the forming quality and uniformity of the finished yarn, reducing the number of downtimes and manual interventions during production, improving overall production efficiency, reducing equipment failure rate and maintenance costs, and ensuring long-term stable and reliable operation of the device.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 4 This invention provides a technical solution: a dynamic compensation device for the winding tension of a spinning machine, comprising...

[0036] Mounting plate 100;

[0037] The guide component is rotatably mounted on the surface of the mounting plate 100;

[0038] The surface of the mounting plate 100 is provided with a protective component 200, which is composed of protective components and functional components;

[0039] One end of the protective component is sleeved on the yarn 103, and the other end is mounted on the surface of the mounting plate 100; the functional component is mounted on one end of the protective component, and the output end of the functional component reduces radial runout by pressing down the yarn 103; a detection part is also provided on the functional component.

[0040] In this embodiment, the protective component is a composite structure consisting of a metal plate 201 and a protective sleeve 204. The metal plate 201 is mounted on the mounting plate 100, while the protective sleeve 204 is fitted over the yarn 103. The metal plate 201 is used to fit the mounting plate 100, and the protective sleeve 204 is used to cover the yarn 103, preventing the yarn 103 from jumping or detaching.

[0041] In this embodiment, a movable groove 202 is also provided on the surface of the metal plate 201, and a connecting bolt 208 that passes through the movable groove 202 is fixed on the surface of the mounting plate 100. A locking nut 209 is screwed on the outer surface of the connecting bolt 208. The locking nut 209 abuts against the surface of the metal plate 201. Through the cooperation of the locking nut 209 and the connecting bolt 208, the installation of the metal plate 201 and the mounting plate 100 can be realized. At the same time, the position of the metal plate 201 can be adjusted by moving the movable groove 202 to ensure the stable installation of the protective sleeve 204 on the yarn 103.

[0042] In this embodiment, the functional components are a miniature cylinder 203 installed on the outer wall of the protective sleeve 204 and a pressure sleeve 205 disposed inside the protective sleeve 204.

[0043] The top of the pressure sleeve 205 extends horizontally outward and forms an extension 210. The output end of the micro cylinder 203 is mounted on the extension 210. When the yarn 103 exhibits radial runout, the micro cylinder 203 drives the pressure sleeve 205 to push towards 104 through the extension 210, thereby further restricting the movement of the yarn 103 and preventing the yarn 103 from exhibiting large-amplitude radial runout that would affect subsequent transmission.

[0044] In this embodiment, a mounting plate 206 is also installed on the outside of the protective sleeve 204. An infrared sensor 207 is installed on the mounting plate 206. The infrared sensor 207 is placed outside the miniature cylinder 203. In use, the amplitude of the yarn 103's jump is first detected by the infrared sensor 207. When the amplitude of the yarn 103's jump is large, the signal is transmitted to the miniature cylinder 203, and the miniature cylinder 203 further limits the yarn 103.

[0045] In this embodiment, the guide consists of multiple guide wheels 101 and a transmission wheel 102. The yarn 103 passes through all the guide wheels 101 and the transmission wheel 102. The transmission wheel 102 can move horizontally. When the transmission wheel 102 moves, it will increase the tension of the yarn 103, thereby achieving the purpose of dynamic compensation.

[0046] In this embodiment, a controller 300 is also installed on the rear surface of the mounting plate 100, and a transmission structure that drives the transmission wheel 102 to move is installed inside the controller 300.

[0047] This invention also discloses a method for controlling a dynamic compensation device for winding tension in a spinning machine, comprising a dynamic compensation device, specifically including the following steps:

[0048] Step 1: Pass the yarn 103 through all the guide wheels 101 and transmission wheels 102 on the surface of the mounting plate 100 in sequence according to the preset transmission path. Put the protective sleeve 204 in the protective component 200 on the outside of the yarn 103. Push the metal plate 201 so that the connecting bolt 208 on the surface of the mounting plate 100 slides in the moving groove 202 of the metal plate 201. Adjust the position of the metal plate 201 and the protective sleeve 204 so that the axis of the protective sleeve 204 and the yarn 103 are matched. Then tighten the locking nut 209 on the outside of the connecting bolt 208 so that the locking nut 209 is tightly abutted against the surface of the metal plate 201, and complete the fixation of the metal plate 201 and the mounting plate 100, so as to achieve precise positioning of the protective component 200 on the surface of the mounting plate 100.

[0049] Step 2: Parameter settings are made through the controller 300 on the rear surface of the mounting plate 100. First, the normal tension threshold range for the winding process of yarn 103 is input. Then, the warning threshold for the radial runout of yarn 103 detected by infrared sensor 207 is set. At the same time, according to the specifications and processing requirements of yarn 103, the output end pushing stroke, pushing force, and reset time parameters of pressure sleeve 205 of micro cylinder 203 are preset to complete the matching of the operating parameters of controller 300 and each functional component, ensuring the linkage response accuracy of detection unit and functional component.

[0050] Step 3: Start the spinning machine to drive the guide wheel 101 and the transmission wheel 102 to rotate, driving the yarn 103 to perform transmission and winding operations along the preset path. During this process, the infrared sensor 207 installed on the mounting plate 206 outside the protective sleeve 204 continuously detects the radial runout amplitude of the yarn 103 in real time and transmits the data to the controller 300. At the same time, the controller 300 synchronously collects and monitors the winding tension data of the yarn 103, realizing dual detection of the operating status of the yarn 103.

[0051] Step 4: When the infrared sensor 207 detects that the radial runout of the yarn 103 exceeds the preset warning threshold, it immediately transmits the runout over-limit signal to the controller 300. The controller 300 sends a drive command to the micro cylinder 203. The output end of the micro cylinder 203 extends outward and pushes the extension 210 at the top of the pressure sleeve 205, causing the pressure sleeve 205 inside the protective sleeve 204 to press down towards the yarn 103. Through the contact and adhesion between the pressure sleeve 205 and the yarn 103, the radial movement range of the yarn 103 is limited until the infrared sensor 207 detects that the runout of the yarn 103 has returned to within the warning threshold. The controller 300 sends a reset command, and the micro cylinder 203 drives the pressure sleeve 205 to reset to the initial position, releasing the downward pressure limit on the yarn 103.

[0052] Step 5: The controller 300 continuously compares and analyzes the real-time collected yarn 103 winding tension data with the preset normal tension threshold range. When the tension data is detected to exceed the threshold range and a tension deviation occurs, the controller 300 activates the internal transmission structure. The transmission structure drives the transmission wheel 102 to move horizontally on the surface of the mounting plate 100. By changing the position of the transmission wheel 102, the winding path and stretching length of the yarn 103 are adjusted, thereby precisely adjusting the tension of the yarn 103 and realizing dynamic compensation of the winding tension, so that the winding tension of the yarn 103 is always maintained within the preset normal threshold range.

[0053] Step Six: Throughout the entire winding process of the spinning machine, the infrared sensor 207 continuously monitors the radial runout of the yarn 103, the micro cylinder 203 and the pressure sleeve 205 dynamically suppress the runout, and the controller 300 continuously monitors the winding tension and performs tension compensation operations on the transmission wheel 102 until the winding of the yarn 103 is completed. Then, the spinning machine and the controller 300 are turned off, completing the entire dynamic compensation operation for winding tension.

[0054] Although embodiments of the invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

Then, the warning threshold for the radial runout of the yarn (103) detected by the infrared sensor (207) is set. At the same time, according to the specifications and processing requirements of the yarn (103), the output end pushing stroke, pushing force and reset time parameters of the pressure sleeve (205) of the micro cylinder (203) are preset to complete the matching of the operating parameters of the controller (300) and each functional component, and ensure the linkage response accuracy of the detection unit and the functional components. Step 3: Start the spinning machine to drive the guide wheel (101) and the transmission wheel (102) to rotate, driving the yarn (103) to carry out transmission and winding operations along the preset path. During this process, the infrared sensor (207) installed on the mounting plate (206) outside the protective sleeve (204) continuously detects the radial runout amplitude of the yarn (103) in real time and transmits the data to the controller (300).
