Description

Technical Field

[0001] This invention relates to a double take-up mechanism and textile machine for high-tension warp yarn textiles, belonging to the technical field of textile equipment. Background Technology

[0002] A textile machine is a device that processes raw materials such as yarn, silk, and hemp into threads and then weaves them into fabric. Currently, automatic textile machines are widely used in the textile industry. During the weaving process of an automatic textile machine, because it requires significant tension during take-up, the fabric often tightens in the width direction, resulting in uneven weave thickness and affecting fabric quality. To prevent excessive tightening in the width direction, edge supports are used to control the fabric's width contraction, ensuring uniform fabric thickness.

[0003] In the existing technology, when weaving thick fabrics with high weft density, the textile machine often experiences insufficient tension, making it difficult to quickly wind up the woven fabric to the next feed stroke. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a double take-up mechanism and a textile machine for high warp tension textile fabrics, which solves the problem of insufficient take-up tension in the prior art for high weft density fabrics.

[0005] The technical problem to be solved by the present invention is achieved by the following technical solution: a double take-up mechanism for high-tension warp yarn textiles, comprising a main support frame disposed at the outlet of a textile machine; a first take-up assembly comprising a first take-up roller, a first guide roller, and a first transition roller disposed parallel to the main support frame; a second take-up assembly disposed on the main support frame, the second take-up assembly comprising a second take-up roller and a second guide roller; and a tension roller disposed between the first take-up assembly and the second take-up assembly for adjusting the tension of the fabric winding; wherein, the maximum winding arc length of the fabric wound around the first take-up roller after being output from the textile machine is greater than half of its outer circumference.

[0006] By adopting the above technical solution, a double-take method is used to wind up the fabric, replacing the traditional full-width side support. The double-take method, combined with a tension roller, adjusts the winding tension of the entire take-up mechanism in real time, ensuring the fabric's winding tension and making it better suited for high-density fabric weaving. By controlling the winding area of ​​the fabric on the first take-up roller, the wrap angle and friction between the fabric and the roller surface are significantly increased. This allows the fabric to be pulled more firmly, preventing slippage and meeting the stable winding requirements of high warp tension fabrics. Furthermore, the first take-up assembly is used for the coarse take-up under high tension, while the second take-up assembly performs the final take-up, effectively reducing the tension on a single roller.

[0007] The present invention is further configured such that the tension roller is connected to a control module for controlling the tension magnitude.

[0008] By adopting the above technical solution, the tension of the tension roller can be adjusted in real time, thus better adapting to the winding of high-density fabrics. Real-time tension adjustment of the tension roller allows for active tension detection and regulation of the fabric output from the first take-up roller. This compensates for tension fluctuations in the first stage before the fabric enters the second take-up roller, preventing backlash during the fabric winding process and achieving more uniform and precise tension winding.

[0009] The present invention is further configured such that the lateral distance between the first take-up roller and the second take-up roller is less than 20 cm.

[0010] By adopting the above technical solution, a relatively compact spatial layout is maintained while using dual winding, making reasonable use of every space and effectively reducing the overall volume of the winding mechanism.

[0011] The present invention is further configured such that: both the first take-up roller and the second take-up roller are detachably wound with a winding layer for increasing the friction with the fabric, and the winding angle of the winding layer relative to the fabric transport direction is greater than 10°.

[0012] By adopting the above technical solution, the winding layer can greatly increase the friction between the fabric and the first and second take-up rollers, reduce the relative sliding generated during the fabric winding process, and improve the winding force.

[0013] The present invention is further configured such that: a feeding roller is provided at the feed inlet of the first take-up assembly, and after the fabric is output from the textile machine, it first passes over the top of the feeding roller and then passes through the first take-up roller.

[0014] By adopting the above technical solution, the fabric can be quickly guided to the predetermined path.

[0015] The present invention is further configured such that: a tension sensor is provided on the tension roller, and the tension sensor detects the tension of the tension roller and feeds it back to the control module.

[0016] By adopting the above technical solution, the tension of the tension roller can be adjusted in real time through the control module, thereby releasing the tension reasonably according to the actual working conditions, and thus adjusting the winding speed and winding density of the fabric.

[0017] The present invention is further configured such that: one or both ends of the first guide roller are provided with deflection plates, one end of the deflection plate is connected to the first guide roller, the other end is a free end, and the middle section of the deflection plate is rotatably connected to the main support.

[0018] By adopting the above technical solution, the distance between the first guide roller and the first take-up roller can be controlled by the deflection plate. This allows the first guide roller with the fabric to be pressed and adhered to the first take-up roller by adjusting the deflection angle of the deflection plate during subsequent fabric take-up, thereby controlling the take-up tension of the fabric.

[0019] The present invention is further configured such that: an adjusting screw is provided at the free end of the deflection plate, and an adjusting sleeve is rotatably provided on the main support, wherein the adjusting screw is rotatably connected to the adjusting sleeve.

[0020] By adopting the above technical solution, the deflection angle of the deflection plate is adjusted by bolts, which has higher precision, a wider spacing gradient between the first guide roller and the first take-up roller, and can quickly adjust a variety of different spacings according to the different fabric thicknesses.

[0021] The present invention is further configured such that: a control panel is provided above the main support, including a number of control buttons and an emergency stop button for emergency stop.

[0022] By adopting the above technical solution, operators can quickly and easily control the winding mechanism.

[0023] This application also relates to a textile machine, wherein the outlet of the textile machine is equipped with a double take-up mechanism, and the double crimping mechanism is used to take up the fabric.

[0024] By adopting the above technical solution, after integrating the double take-up mechanism at the outlet of the textile machine, the whole machine has the ability to stably take up fabrics with high warp tension, which expands the process application range of the textile machine and avoids stopping or fabric defects caused by take-up slippage or tension loss.

[0025] The beneficial effects of this invention are: By employing a dual take-up mechanism to wind up the fabric and controlling its feed, the take-up tension can be effectively increased, preventing backlash during weaving and improving the uniformity of the woven fabric. By controlling the fabric winding radius on the first take-up roller to be greater than half the roller's radius, the friction surface between the fabric and the first take-up roller can be effectively increased, thus preventing slippage and ensuring continuous stability of the take-up tension.

[0026] By installing a tension roller between the first and second take-up assemblies, the take-up tension of the fabric can be effectively adjusted, isolating the first and second take-up assemblies. The first take-up assembly initially pulls out the woven fabric, applies a certain tension to it via the tension roller, and then controls the second take-up assembly to take it up. Throughout the process, the tension of the tension roller can be adjusted in real time by the control system, thus adapting to the take-up of fabrics of different thicknesses and weaving speeds.

[0029] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0030] like Figure 1 As shown, a double take-up mechanism for high-tension warp yarn textile fabric includes a main support 1 installed at the outlet of a textile machine. A first take-up assembly 2 and a second take-up assembly 3 are installed on the main support 1. The first take-up assembly 2 is located above the second take-up assembly 3. A tension roller 4 is located between the first take-up assembly 2 and the second take-up assembly 3. Both the first take-up assembly 2 and the second take-up assembly 3 are driven by a motor.

[0031] The first take-up assembly 2 includes a first take-up roller 210, a first guide roller 220 and a first transition roller 230, which are mounted in parallel on the main support 1. The first take-up roller 210 is located between the first guide roller and the first transition roller 230.

[0032] The second take-up assembly 3 includes a second take-up roller 310 and a second guide roller 320 mounted parallel to each other on the main support 1. The second guide roller 320 is located to the left of the second take-up roller 310.

[0033] like Figure 2 As shown, after the fabric 10 is woven, it enters the double take-up mechanism from the outlet of the textile machine. First, it passes above the feed roller 5 located on the right side of the first take-up assembly 2, and then enters from below the first take-up roller 210. After winding around the first take-up roller 210, it exits from the gap between the first take-up roller 210 and the first guide roller 220, passes over the top of the first guide roller 220, and extends downward to the lower surface of the first transition roller 230, completing the winding transition on the first take-up assembly 2.

[0034] After passing through the first transition roller 230, the fabric 10 adheres to the upper surface of the tension roller 4, extends downward from the other side of the tension roller 4 to the lower surface of the second take-up roller 310, passes through the gap between the second take-up roller 310 and the support of the second guide roller 320, passes around the second guide roller 320, and is fed into an external winding device for winding.

[0035] During the winding process described above, the fabric 10 is initially wound up by the first take-up roller 210, and a corresponding tension is applied by the tension roller 4. This prevents the fabric 10 from returning to its original position after being fed into the tension roller 4 via the first take-up assembly 2. Each feed stroke of the fabric 10 in the first take-up assembly 2 can be quickly transferred to the second take-up assembly 3 via the tension roller 4. Therefore, there is no need to worry about the fabric 10 returning to its original position and causing uneven weave thickness during the entire winding process. The second take-up roller 310 works in conjunction with the tension roller 4 to consistently apply winding tension to the fabric 10, preventing the fabric 10 from being unloaded.

[0036] Furthermore, the maximum winding arc length of the fabric 10 wound on the first take-up roller 210 after being output from the textile machine is greater than half of its outer circumference. By controlling the winding area of ​​the fabric 10 on the first take-up roller 210, the wrap angle and friction between the fabric 10 and the roller surface can be significantly increased, making the tension application more stable throughout the take-up process, avoiding slippage, and meeting the stable winding requirements of the high warp tension fabric 10.

[0037] In the above embodiment, the lateral distance between the first take-up roller 210 and the second take-up roller 310 is less than 20 cm. A large-diameter transmission gear is installed at the same shaft end on both the first take-up roller 210 and the second take-up roller 310. Simultaneously, a small-diameter power gear meshes with each of the two transmission gears, used to drive the motor of the first take-up assembly 2 and the motor of the second take-up assembly 3. Their output shafts are respectively connected to the two small-diameter power gears. In this embodiment, the mounting points of the two motors are located diagonally opposite each other on the outer side of the main support 1, with the motor on the first take-up assembly 2 located at the upper right corner and the motor on the second take-up assembly 3 located at the lower left corner.

[0038] By using gear meshing to stagger the mounting points of the two motors, two motors can be installed and driven in a relatively compact space, effectively utilizing most of the space and reducing the overall footprint of the dual take-up mechanism.

[0039] It should be noted that the motors used to drive the first winding assembly 2 and the second winding assembly 3 are all servo motors, and a reducer is provided between the two motors and the two power gears.

[0040] A control module (not shown) is connected to the tension roller 4 to control its tension. The tension roller 4 can automatically adjust the tension through the control module, thereby better adapting to the winding operation of the high-density fabric 10. Furthermore, due to the setting of the tension roller 4, the first take-up assembly 2 and the second take-up assembly 3 can be isolated from each other, so that the fabric 10 is further pre-tensioned when entering the second take-up assembly 3.

[0041] Furthermore, a tension sensor is also installed on the tension roller 4, which can detect the tension of the tension roller 4 in real time and feed the detected tension roller 4 back to the control module in real time, so that the control module can accurately adjust the tension of the tension roller 4.

[0042] It should be noted that the tension adjustment method and control module of the tension roller 4 are already mature technologies in the existing technology. The specific structural details and system adjustment method of the tension roller 4 will not be described in detail here.

[0043] In one embodiment, a winding layer 12 is detachably wound on both the first take-up roller 210 and the second take-up roller 310. The winding angle of the winding layer 12 relative to the conveying direction of the fabric 10 must be greater than 10°. The outer surface of the winding layer 12 is provided with a dense array of friction protrusions. When the fabric 10 is wound on the first take-up roller 210 and the second take-up roller 310, it directly contacts and adheres to the winding layer 12. The winding layer 12 can effectively increase the friction force on the fabric 10, thereby better converting the axial driving force of the first take-up roller 210 and the second take-up roller 310 into the winding tension on the fabric 10, and controlling the stable conveying of the fabric 10. The detachable installation method allows for quick replacement of the winding layer 12 during subsequent maintenance after the friction protrusions have been worn down over a long period of use.

[0044] like Figure 2 As shown, a feed roller 5 is installed at the feed inlet of the first take-up assembly 2. The feed roller 5 can adjust the longitudinal spacing relative to the first take-up assembly 2, thereby adjusting the maximum winding area between the fabric 10 and the first take-up roller 210 to ensure that the winding arc length between the fabric 10 and the first take-up roller 210 is greater than half of the circumference length of the first take-up roller 210.

[0045] Furthermore, a limiting roller 11 is provided on the lower right side of the second take-up roller 310 to guide the fabric 10.

[0046] In one embodiment, a deflection plate 6 is installed at one or both ends of the first guide roller 220. One end of the deflection plate 6 is fixedly sleeved on the end of the first guide roller 220, serving as a support point for the first guide roller 220 and rotatably connected to it. The other end is a free end 610, and the middle section is rotatably connected to the main support 1, allowing the entire deflection plate 6 to rotate around the central rotatable connection point. Under normal conditions, the entire first guide roller 220 will automatically fall down due to its own weight and come into contact with the first take-up roller 210 below it, pressing the fabric 10 tightly against the first guide roller 220 and the first take-up roller 210, thereby increasing the take-up tension. In this embodiment, a mounting plate 13 is installed at one end of the first take-up roller 210, and the end of the first take-up roller 210 is rotatably connected to the mounting plate 13, which is fixed to the entire main support 1. The middle section of the deflection plate 6 is rotatably connected to the mounting plate 13.

[0047] When the fabric 10 needs to be wound, the first guide roller 220 is lifted by rotating the deflector plate 6, so that a gap appears between the first guide roller 220 and the first take-up roller 210. After the fabric 10 passes through, the first guide roller 220 is lowered again to press the fabric 10 together, so as to facilitate the subsequent take-up and extraction of the fabric 10 from the textile machine.

[0048] Furthermore, based on the above embodiment, a threaded hole is provided at the free end 610 of the deflection plate 6, and an adjusting screw 7 is inserted into the threaded hole. At the same time, an adjusting sleeve 8 is rotatably installed on the main support 1. One end of the adjusting screw 7 has a threaded knob in the adjusting sleeve 8, and the other end is provided with a knob head. The knob head can be an internal hexagonal head or an external hexagonal head, which allows the operator to quickly rotate the adjusting screw 7. In addition, a positioning nut 14 is also fitted on the adjusting screw 7. After the adjusting screw 7 is turned to the predetermined position, the positioning nut 14 is rotated until it abuts against the surface of the free end 610 of the deflection plate 6, applying a preload force to the adjusting screw 7. This can prevent the adjusting screw 7 from loosening during the operation of the equipment, which would cause the distance between the first guide roller 220 and the first take-up roller 210 to change and affect the quality of the fabric 10.

[0049] Compared to directly pressing the fabric 10 by its own weight, the above embodiment uses an adjusting screw 7 and an adjusting sleeve 8 to adjust the angle of the first guide roller 220, which makes the spacing adjustment accuracy between the first guide roller 220 and the first take-up roller 210 higher. For fabrics 10 of different thicknesses, more reasonable pressing gaps can be adjusted.

[0050] like Figure 1As shown, a control panel 9 is also installed on the main support 1. The control panel 9 includes several control buttons 910 and an emergency stop button 920. The control buttons 910 are used to adjust the winding speed and power supply of the entire dual winding mechanism, while the emergency stop button 920 is used to control the entire dual winding mechanism to perform an emergency stop.

[0051] Based on the above embodiments, this application also relates to a textile machine, in which a double take-up mechanism as described in the above embodiments is installed at the outlet of the textile machine. The fabric 10 woven by the textile machine is taken up and fed through the double take-up mechanism. In this embodiment, the main support 1 of the double take-up mechanism is fixed at the outlet of the textile machine, and is a separate main body from the mounting bracket of the textile machine. In other embodiments, the main support 1 of the double take-up mechanism can also be directly mounted on the mounting bracket of the textile machine. By extending an additional mounting section outward from the outlet of the textile machine, the first take-up assembly 2 and the second take-up assembly 3 are directly mounted on the extended mounting section of the mounting bracket of the textile machine, thereby making the structure of the entire textile machine more compact.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention.
