Description

Technical Field

[0001] The present invention relates to the technical field of textile equipment, and in particular to a high-precision weft straightening device for fabrics and a control method thereof. Background Art

[0002] During the dyeing and finishing process, fabrics are constantly being pulled and affected by various mechanical movements and production operations, often resulting in weft yarns being skewed or bent. This phenomenon is called weft skew. If weft skew is not corrected in a timely manner, it will greatly affect the fabric's reprocessing and sales, and seriously affect the quality of the finished product.

[0003] A weft straightener is a mechanical device used to correct weft yarn deformations, such as skew and bend, that occur during the weaving process. It primarily detects the position and state of the weft yarn and then applies an appropriate force to the fabric using mechanical, photoelectric, hydraulic, or pneumatic means to restore the weft yarn to its normal, perpendicular position relative to the warp yarn, ensuring the fabric's weft-wise flatness and regularity.

[0004] Publication number CN113846477B discloses a corrective mechanism for correcting irrational weft bends in textile fabrics. The mechanism relates to the field of textile fabric mechanisms and includes a curved plate with two brackets symmetrically positioned at its ends. A roller is positioned between the two brackets. The roller comprises a shaft core, multiple partitions, and a rubber sleeve. The shaft core end is connected to the bracket, and multiple partitions are equidistantly arranged on the shaft core rod. The rubber sleeve is positioned outside the partitions. The corrective mechanism for correcting irrational weft bends in textile fabrics uses the principle that like charges repel and opposite charges attract in a magnetic field. The electromagnetic module's magnetic field direction is altered by cooperating with a plug, a socket, and a motor. This forces two extrusion rings to move away from or toward each other. The extrusion rings, partitions, an elastic rubber liner, and the rubber sleeve are used to adjust various areas of the roller. This eliminates wrinkles in traditional devices that require multiple roller sets, simplifying the previously cumbersome and complex operation.

[0005] Although the aforementioned correction mechanism can eliminate wrinkles by adjusting various areas of the roller through the cooperation of the extrusion ring, the partition, the elastic rubber liner, and the rubber sleeve, thereby replacing multiple roller sets to simplify the operation steps, because the inner walls of the rubber sleeve at both ends are fixedly bonded to the partition, when the rubber sleeve bulges, the diameter of the rubber sleeve in the middle will be larger than the diameter at the ends, resulting in different diameters of the longitudinal sections of the rubber sleeve. As a result, the contact state between the rubber sleeve and the fabric at different positions is also different, and the weft straightening effect on the fabric cannot be guaranteed. Secondly, when straightening some thick fabrics or fabrics with severe weft skew, the smooth rubber sleeve cannot provide sufficient friction with the fabric, so the weft straightening force cannot be effectively applied to the fabric, resulting in poor weft straightening effect.

[0006] Therefore, it is necessary to invent a high-precision weft straightening device for fabrics and a control method thereof to solve the above problems. Summary of the Invention

[0011] Preferably, a plurality of second air holes connected to the outside of the corresponding supporting partition are opened on one side of each of the expansion portions.

[0012] Preferably, it also includes a blowing assembly, which is arranged between the core shaft and the supporting partition and can blow air to the surface of the fabric. The blowing assembly includes an air duct, which is opened inside the core shaft; an air inlet channel, which is opened inside the supporting partition, and one end is connected to the air duct, and the other end is connected to between the sleeve and the core shaft; an air outlet channel, which is opened inside the supporting partition, and one end is connected to between the sleeve and the core shaft, and the other end is connected to the outside of the supporting partition; an air inlet pipe, which is rotatably arranged at one end of the core shaft and is connected to the air duct.

[0013] Preferably, it also includes a horizontal adjustment component, which is arranged in the middle of the top of the machine base and can adjust the horizontal angle of the weft straightening roller. The horizontal adjustment component includes a rotating seat, which is rotatably arranged in the middle of the top of the machine base; a connecting plate, which is fixedly arranged on one side of the rotating seat; and a first telescopic member, whose fixed end is rotatably arranged at the top of the machine base, and the movable end is rotatably connected to the connecting plate.

[0014] Preferably, it also includes a vertical adjustment component, which is arranged at the top of the rotating seat and can adjust the vertical angle of the weft straightening roller. The vertical adjustment component includes a connecting ear, which is fixedly arranged on one side of the top of the rotating seat; a mounting seat, which is located above the rotating seat and is rotatably connected to the connecting ear, and the core shaft is rotatably arranged in the middle of the mounting seat; a second telescopic member, whose fixed end is fixedly arranged on the other side of the top of the rotating seat; and a connecting frame, whose bottom end is rotatably connected to the movable end of the second telescopic member, and the top end is rotatably connected to the bottom of the mounting seat.

[0016] Preferably, an industrial camera is also included, which can monitor the weft condition of the fabric. There are multiple industrial cameras, which are evenly arranged on the front side of the mounting frame.

[0017] A control method for a high-precision weft straightening device for fabrics is also provided, comprising the following steps:

[0018] Step 1: The fabric is passed through multiple guide rollers, weft straightening rollers, and discharge rollers in sequence to complete the placement of the fabric on the weft straightening equipment, and the weft skew of the fabric is monitored by an industrial camera;

[0019] Step 2: When the fabric is skewed as a whole, the angle of the weft straightening roller is adjusted by adjusting the horizontal adjustment component and the vertical adjustment component to straighten the weft of the fabric as a whole;

[0020] Step 3: When the fabric has a slight weft skew locally, the location where the weft skew occurs is determined, and the air storage assembly at the corresponding location is controlled to move to the first extrusion state, so that the corresponding expansion portion expands outward, thereby driving the corresponding rubber sleeve to expand, so that the circumferential diameter of the rubber sleeve expands and contacts the location where the weft skew occurs, thereby straightening the weft at the location where the weft skew occurs;

[0021] Step 4. When the fabric has serious weft skew, or the thick fabric has weft skew, the smooth surface of the weft straightening roller will not be able to effectively straighten it. At this time, the air storage component is controlled to move further to the second extrusion state, and the push-up component pushes against the rubber sleeve. The protrusions on the push-up plate will force multiple bosses of the same shape to appear on the outer surface of the rubber sleeve, thereby increasing the friction between the rubber sleeve and the fabric, thereby ensuring the weft straightening effect.

[0022] Technical effects and advantages of the present invention:

[0023] 1. The present invention adjusts the air storage assembly at the position corresponding to the weft skew to the first extrusion state, so that the expansion part at the corresponding position and the rubber sleeve expand and expand synchronously, and locally adjusts the weft straightening roller based on this line of sight. The adjusted weft straightening roller only contacts the part of the fabric where the weft skew occurs, thereby realizing separate weft straightening of the fabric at the weft skew part. Fabrics other than the weft skew do not contact the weft straightening roller, avoiding affecting parts other than the weft skew of the fabric.

[0024] 2. The present invention controls the rubber sleeve to expand and expand synchronously with the expansion portion, so that the longitudinal sections of the rubber sleeve always maintain the same diameter after expansion, and the outer diameter of the rubber sleeve always maintains the same diameter. The situation where the middle diameter of the rubber sleeve is larger than the diameters at both ends will not occur. In this way, the same contact state is maintained between the rubber sleeve and the fabric at all positions after expansion and expansion, thereby ensuring the local weft straightening effect of the weft straightening roller.

[0025] 3. The present invention further squeezes the air storage assembly to a second squeezing state, so that the abutting plate presses outward against the inner surface of the rubber sleeve, thereby forcing the outer surface of the rubber sleeve to form multiple bosses, thereby increasing the friction between the rubber sleeve and the fabric, so that the weft straightening force can act on the fabric more effectively, thereby achieving weft straightening of thick fabrics or fabrics with severe weft skew, enhancing the applicability of the equipment and improving the weft straightening effect.

[0026] 4. The present invention allows gas to continuously flow through the blower assembly and eventually blow outward toward the fabric, thereby achieving weft straightening while blowing on the fabric surface, preventing lint from adhering to the weft straightening roller, ensuring the weft straightening effect of the weft straightening roller, and improving the cleanliness of the fabric surface. In addition, the continuously flowing gas can take away the heat generated by friction and other reasons during the weft straightening process, reduce the temperature of the weft straightening roller, and ensure the smooth progress of the weft straightening process.

[0027] 5. The present invention provides a horizontal adjustment component, a vertical adjustment component, an air storage component and a top support component, so that the weft straightening roller can be adaptively adjusted according to different actual weft skew conditions, thereby realizing weft straightening operations for different types of fabrics and weft skew types, and enhancing the applicability of the equipment.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] In embodiment 1, the present invention provides Figures 1 to 16 The high-precision weft straightening equipment for fabrics shown includes a machine base 1 , and a mounting frame 2 is fixedly provided on the front side of the top end of the machine base 1 .

[0047] It also includes: a plurality of guide rollers 3, which are rotatably arranged in the middle of the mounting frame 2. The plurality of guide rollers 3 can guide and tension the fabric.

[0048] The weft straightening roller 4 can straighten the weft of the fabric with weft skew.

[0049] Specifically, the weft straightening roller 4 includes a core shaft 401, which is rotatably arranged above the middle part of the machine base 1; a plurality of support partitions 402 are provided, and the plurality of support partitions 402 are coaxially fixedly arranged on the outer periphery of the core shaft 401, and the outer periphery of each support partition 402 is provided with two accommodating grooves 403, which are annular and extend to the outer periphery of the corresponding support partition 402; a plurality of sleeves 404 are provided, and each sleeve 404 is fixedly arranged between two adjacent support partitions 402, and is coaxially sleeved on the outside of the core shaft 401, and a first enclosed space is formed between the sleeve 404 and the two adjacent support partitions 402 and the core shaft 401.

[0050] There are multiple gas storage components 405 , and each gas storage component 405 is disposed inside a corresponding sleeve 404 and is communicated with the outside of the corresponding sleeve 404 .

[0051] More specifically, each gas storage assembly 405 includes a gas storage portion 4051, which is arranged inside the corresponding sleeve 404 and sleeved on the outer periphery of the core shaft 401, and is pre-filled with gas. The gas storage portion 4051 itself is elastic and can automatically return to an expanded state when not subjected to external force; the gas storage portion 4051 is provided with a plurality of first air holes 4052 connected to the outside of the corresponding sleeve 404. When the gas storage portion 4051 is squeezed, the gas inside it can flow to the outside of the corresponding sleeve 404 through the first air holes 4052; there are two squeezing plates 4053, which are both sleeved on the outer periphery of the core shaft 401 and symmetrically arranged on both sides of the corresponding gas storage portion 4051. The two squeezing plates 4053 can squeeze the gas storage portion 4051; the driving motor 40 54, which is fixedly arranged on the outer periphery of the core shaft 401; the bidirectional screw rod 4055, which is fixedly connected to the output shaft of the driving motor 4054, and the corresponding two extrusion plates 4053 are respectively threadedly connected to the two ends of the bidirectional screw rod 4055.

The guide rod 4056 can further limit the extrusion plate 4053, so that the extrusion plate 4053 can only slide along the core shaft 401, and will not rotate relative to the core shaft 401, so that the extrusion plate 4053 can stably extrude the gas storage part 4051.

[0052] The expansion portion 406 is provided in a plurality of numbers. Each expansion portion 406 is sleeved in the corresponding receiving groove 403 and can expand toward the outside of the corresponding support partition 402. The expansion portion 406 is provided in a ring shape that matches the receiving groove 403, and the expansion portion 406 itself has elasticity. When the internal air pressure of the expansion portion 406 increases, the expansion portion 406 will expand toward the outside of the receiving groove 403, and the expanded expansion portion 406 still maintains a ring shape. When the internal air pressure of the expansion portion 406 decreases, the expansion portion 406 will automatically shrink to the corresponding receiving groove 403. Each expansion portion 406 has a plurality of expansion portions on one side. A second air hole 409 is connected to the outside of the corresponding supporting partition 402, and air is inflated and discharged into the expansion part 406 through the second air hole 409 to achieve expansion and contraction of the expansion part 406; there are multiple rubber sleeves 407, and each rubber sleeve 407 is fixedly set between the corresponding two expansion parts 406. When the expansion part 406 expands outward, it will drive the corresponding rubber sleeve 407 to expand synchronously, and during the expansion process, the outer periphery of the expansion part 406 and the rubber sleeve 407 always remains circular, and a second enclosed space is formed between the rubber sleeve 407, the corresponding expansion part 406 and the sleeve 404.

[0053] There are multiple abutting components 408 , which are evenly arranged on the outer circumference of the sleeve 404 . The abutting components 408 can abut and squeeze the rubber sleeve 407 so that multiple bosses appear on the outer circumferential surface of the rubber sleeve 407 .

[0054] More specifically, the push-up assembly 408 includes an air guide cavity 4081, the number and position of which are consistent with the first air hole 4052, the air guide cavity 4081 is fixedly arranged on the outer periphery of the sleeve 404, and each first air hole 4052 is communicated with the corresponding air guide cavity 4081; a ventilation groove 4082 is opened through the side of the air guide cavity 4081, and the first enclosed space and the second enclosed space are communicated with the ventilation groove 4082 through the first air hole 4052; a piston plate 4083 is sealingly and slidably arranged inside the air guide cavity 4081, and a third enclosed space is formed between the piston plate 4083 and the air guide cavity 4081; an elastic member 4084 is fixedly arranged between the piston plate 4083 and the air guide cavity 4081, and the elastic member 4084 can push the piston plate 4083 to move in the air guide cavity 4081 toward the sleeve 404, and when the elastic member 4084 pushes the piston During the movement of plate 4083, the position of piston plate 4083 will never overlap with the ventilation groove 4082, that is, the third confined space is always in a sealed state. In the initial state, the air pressure in the third confined space is lower than the air pressure outside it, and the piston plate 4083 is maintained at a position close to the sleeve 404 by the thrust of the elastic member 4084. At this time, the third confined space is in a state of minimum air pressure and maximum space; the connecting rod 4085 is fixedly arranged on the side of the piston plate 4083 away from the sleeve 404, and the connecting rod 4085 passes through the outside of the air guide cavity 4081; the top plate 4086 is fixedly arranged at one end of the connecting rod 4085 outside the air guide cavity 4081, and the curvature of the top plate 4086 is consistent with the curvature of the inner circular surface of the rubber sleeve 407 after it is expanded to the maximum extent; there are multiple protrusions 4087, and they are evenly fixed on the outside of the top plate 4086.

[0055] The discharging roller 5 is rotatably arranged at the rear side of the top end of the machine base 1, and the discharging roller 5 can discharge and tension the fabric.

[0056] The air blowing assembly 6 is arranged between the core shaft 401 and the supporting partition 402 and can blow air toward the surface of the fabric.

[0057] Specifically, the blast assembly 6 includes an air duct 601, which is opened inside the core shaft 401; an air inlet channel 602, which is opened inside the support baffle 402, and one end is connected to the air duct 601, and the other end is connected to the space between the sleeve 404 and the core shaft 401; an air outlet channel 603, which is opened inside the support baffle 402, and one end is connected to the space between the sleeve 404 and the core shaft 401, and the other end is connected to the outside of the support baffle 402; an air inlet pipe 604, which is rotatably arranged at one end of the core shaft 401 and is connected to the air duct 601. The air inlet pipe 604 can be connected to an external air compressor to provide gas to the air duct 601. In the process of weft straightening the fabric, gas is supplied through the air inlet pipe 604. The air passage 601 is continuously filled with gas, and the gas in the air passage 601 will enter the first enclosed space through the air inlet passage 602, and then be continuously blown outwards toward the fabric through the air outlet passage 603, thereby achieving the purpose of blowing and cleaning the surface of the fabric during the weft straightening process, and preventing a large amount of impurities such as lint from adhering to the surface of the fabric. At the same time, it can also prevent lint from adhering to the weft straightening roller 4, and maintain the cleanliness of the weft straightening roller 4, thereby ensuring the weft straightening effect of the weft straightening roller 4. Moreover, since the gas continuously flows through the air passage 601, the air inlet passage 602, the first enclosed space and the air outlet passage 603, it can effectively take away the heat generated by friction and other reasons during the weft straightening process, reduce the temperature of the weft straightening roller 4, and ensure the smooth progress of the weft straightening process.

[0058] The horizontal adjustment component 7 is arranged at the middle of the top end of the machine base 1 and can adjust the horizontal angle of the weft straightening roller 4.

[0059] Specifically, the horizontal adjustment component 7 includes a rotating base 701, which is rotatably arranged in the middle of the top of the machine base 1; a connecting plate 702, which is fixedly arranged on one side of the rotating base 701; a first telescopic member 703, a fixed end of which is rotatably arranged at the top of the machine base 1, and a movable end is rotatably connected to the connecting plate 702. When the first telescopic member 703 is extended, it can push the connecting plate 702 to drive the rotating base 701 to rotate, thereby adjusting the horizontal angle of the weft straightening roller 4 as a whole.

[0060] The vertical adjustment component 8 is arranged at the top of the rotating base 701 and can adjust the vertical angle of the weft straightening roller 4.

[0061] Specifically, the vertical adjustment component 8 includes a connecting ear 801, which is fixedly arranged on one side of the top of the rotating seat 701; a mounting seat 802, which is located above the rotating seat 701 and is rotatably connected to the connecting ear 801, and the core shaft 401 is rotatably arranged in the middle of the mounting seat 802; a second telescopic member 803, a fixed end of which is fixedly arranged on the other side of the top of the rotating seat 701; a connecting frame 804, a bottom end of which is rotatably connected to the movable end of the second telescopic member 803, and the top end is rotatably connected to the bottom of the mounting seat 802. When the second telescopic member 803 is extended, the mounting seat 802 can be pushed by the connecting frame 804 to rotate around the connecting ear 801, so as to adjust the vertical angle of the weft straightening roller 4 as a whole.

[0062] The driving assembly 9 can drive the weft straightening roller 4 to rotate.

[0063] Specifically, the driving assembly 9 includes a driving motor 901, which is fixedly arranged on one side of the mounting base 802; a transmission gear 902, which is fixedly arranged at the output end of the driving motor 901; and a driven gear 903, which is fixedly arranged at one end of the core shaft 401 and meshes with the transmission gear 902. The driving motor 901 drives the transmission gear 902 to rotate, and the transmission gear 902 drives the core shaft 401 to rotate through the driven gear 903, thereby causing the weft straightening roller 4 to rotate.

[0064] The industrial camera 10 can monitor the weft skew of the fabric. A plurality of industrial cameras 10 are provided and are evenly arranged on the front side of the mounting frame 2 .

[0065] In summary, when the fabric has an overall weft skew, the specific situation of the weft skew is observed, and the horizontal adjustment component 7 or the vertical adjustment component 8 is adaptively adjusted to achieve the horizontal or vertical angle adjustment of the weft straightening roller 4 as a whole, thereby achieving the weft straightening operation of the fabric. At this time, the expansion portion 406 and the rubber sleeve 407 are both in the initial state, as shown in FIG. Figure 14 Status shown.

[0066] When the fabric has a local weft skew, first determine the location where the weft skew occurs, and control the driving motor 4054 at the corresponding location to drive the bidirectional screw 4055 to rotate, so that the extrusion plate 4053 squeezes the air storage part 4051, so that the air storage part 4051 is squeezed to the first squeezing state, such as Figure 15 In the state shown, during this process, the gas in the air storage part 4051 will enter the second confined space through the first air hole 4052, and at the same time, the gas entering the second confined space will also enter the expansion part 406 through the second air hole 409. Since the second confined space and the expansion part 406 are in a connected state, the expansion part 406 and the rubber sleeve 407 will expand synchronously, and the circumferential diameter of the rubber sleeve 407 will expand to the maximum state and contact with the fabric with weft skew, so as to achieve weft straightening of the weft skew part of the fabric.

[0067] When the fabric has a serious weft skew, or the fabric is thick and coarse, the driving motor 4054 is controlled to rotate further, so that the squeezing plate 4053 further squeezes the air storage portion 4051, so that the air storage portion 4051 is squeezed to the second squeezing state, such as Figure 16 In the state shown, during this process, since the rubber sleeve 407 is already in the state with the largest circumferential diameter when the gas storage portion 4051 is in the first extrusion state, when the gas storage portion 4051 changes from the first extrusion state to the second extrusion state, the rubber sleeve 407 and the expansion portion 406 no longer expand, and the air pressure filled in the second confined space continues to increase, thereby pushing the piston plate 4083 to overcome the thrust of the elastic member 4084 and move in the air guide cavity 4081 in the direction away from the sleeve 404, and the space of the third confined space gradually decreases. During this process, the air pressure in the third enclosed space is always lower than the air pressure outside it. At this time, the piston plate 4083 will drive the supporting plates 4086 to expand outward through the connecting rod 4085, so that multiple supporting plates 4086 will press against the inner surface of the rubber sleeve 407 after it has expanded to its maximum diameter. At this time, the protrusions 4087 on the supporting plates 4086 will force the outer surface of the rubber sleeve 407 to have multiple bosses with the same shape as the protrusions 4087, thereby increasing the friction between the rubber sleeve 407 and the fabric, thereby realizing the weft straightening operation of the fabric.

[0068] By controlling the extrusion plate 4053 at the position corresponding to the weft skew to squeeze the air storage part 4051, the air storage part 4051 is squeezed to the first extrusion state, so that the expansion part 406 and the rubber sleeve 407 are expanded and supported synchronously, thereby realizing the adjustment of the local position of the weft straightening roller 4, thereby realizing the separate weft straightening of the fabric where the weft skew occurs, and the fabric other than the weft skew does not come into contact with the weft straightening roller 4, avoiding affecting the fabric parts other than the weft skew. At the same time, since the expansion part 406 and the rubber sleeve 407 are always expanded and supported synchronously, the longitudinal sections of the rubber sleeve 407 always maintain the same diameter, and the outer cylindrical surface of the rubber sleeve 407 always maintains a constant diameter state. The situation where the middle diameter of the rubber sleeve 407 is larger than the diameter at both ends will not occur, thereby ensuring the local weft straightening effect of the weft straightening roller 4.

[0069] By controlling the extrusion plate 4053 to further squeeze the air storage portion 4051 to the second extrusion state, the piston plate 4083 drives the abutting plate 4086 to expand outward and finally abut against the inner surface of the rubber sleeve 407, thereby forming a plurality of bosses with the same shape as the protrusions 4087 on the outer surface of the rubber sleeve 407, thereby increasing the friction between the rubber sleeve 407 and the fabric, and the weft straightening force can act on the fabric more effectively, thereby adapting to the weft straightening of thick fabrics or fabrics with severe weft skew, improving the applicability of the equipment, and ensuring the weft straightening effect.

[0070] By continuously introducing gas into the air inlet pipe 604, the gas continuously flows through the air duct 601, the air inlet channel 602, the first enclosed space and the air outlet channel 603 and is finally blown outward toward the fabric, so that the surface of the fabric can be blown during the weft straightening process to prevent the fluff from sticking to the weft straightening roller 4, thereby ensuring the weft straightening effect of the weft straightening roller 4. At the same time, the continuously flowing gas can effectively take away the heat generated by friction and other reasons during the weft straightening process, reduce the temperature of the weft straightening roller 4, and ensure the smooth progress of the weft straightening process.

[0071] The horizontal angle of the weft straightening roller 4 is adjusted as a whole by the horizontal adjustment component 7, the vertical angle of the weft straightening roller 4 is adjusted as a whole by the vertical adjustment component 8, and the air storage component 405 expands and supports the local rubber sleeve 407 of the weft straightening roller 4, so that the weft straightening roller 4 can be adaptively adjusted according to the actual weft skew situation, thereby realizing weft straightening operations for different types of fabrics and weft skew types, and enhancing the applicability of the equipment.

[0072] In a second embodiment, the present invention further provides a method for controlling a high-precision weft straightening device for fabrics, comprising the following steps:

[0073] Step 1: The fabric is passed through multiple guide rollers 3, weft straightening rollers 4, and discharge rollers 5 in sequence to complete the placement of the fabric on the weft straightening equipment, and the weft skew of the fabric is monitored by an industrial camera 10;

[0074] Step 2: When the fabric is skewed as a whole, the angle of the weft straightening roller 4 is adjusted by adjusting the horizontal adjustment component 7 and the vertical adjustment component 8, so as to straighten the weft of the fabric as a whole;

[0075] Step 3: When the fabric has a slight weft skew locally, the location where the weft skew occurs is determined, and the air storage assembly 405 at the corresponding location is controlled to move to the first extrusion state, so that the corresponding expansion portion 406 expands outward, thereby driving the corresponding rubber sleeve 407 to expand, so that the circumferential diameter of the rubber sleeve 407 expands and contacts the location where the weft skew occurs, thereby straightening the weft at the location where the weft skew occurs;

[0076] Step 4. When the fabric has serious weft skew, or the thick fabric has weft skew, the smooth surface of the weft straightening roller 4 will not be able to effectively straighten it. At this time, the air storage component 405 is controlled to move further to the second extrusion state, and the push-up component 408 pushes the rubber sleeve 407. The protrusion 4087 on the push-up plate 4086 will force the outer surface of the rubber sleeve 407 to have multiple bosses of the same shape, thereby increasing the friction between the rubber sleeve 407 and the fabric, thereby ensuring the weft straightening effect.

[0077] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
