Description

Fabric weft skew adjustment structure Technical Field

[0001] This utility model belongs to the technical field of weft skew adjustment equipment, and more specifically, it relates to a weft skew adjustment structure for fabric. Background Technology

[0002] During the dyeing and finishing process, the fabric is continuously under tension and affected by various mechanical movements and production operations, which often leads to weft yarn skew or bending, a phenomenon known as weft skew. If weft skew is not corrected in time, it will affect product quality. Therefore, after dyeing and finishing, weft-skewed fabrics need to be straightened to ensure product quality.

[0003] In existing technologies, the tilt adjustment structure is usually installed on the equipment frame. However, it is connected to the frame by multiple sets of bolted assemblies. When disassembly and maintenance are required, each set of bolted assemblies (bolts and nuts) needs to be disassembled and separated one by one, which is an extremely cumbersome process. Summary of the Invention

[0004] This utility model provides a fabric weft skew adjustment structure that can be quickly disassembled, improving disassembly efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fabric weft skew adjustment structure is provided, comprising two sets of clamping components and an adjustment component. The two sets of clamping components are respectively mounted on two opposing longitudinal beams of the frame. Each set of clamping components includes a first clamping hoop and a second clamping hoop clamping around the outer periphery of the longitudinal beam. The first clamping hoop is located above the second clamping hoop. First wing plates are provided on both sides of the first clamping hoop, and second wing plates are provided on both sides of the second clamping hoop. The two first wing plates and two second wing plates are arranged in a one-to-one correspondence. The outer edge of the first wing plate has a first locking groove with an outward opening, and the outer edge of the second wing plate has a second locking groove with an outward opening, corresponding to the first locking groove. The first wing plate and the second wing plate are connected by bolt assemblies that pass through the first and second locking grooves. The adjustment component is mounted on the two first clamping hoops, and an adjustment roller with a main shaft extending along the interval direction of the two sets of clamping components is rotatably connected to the adjustment component for adjusting the weft skew of the fabric.

[0006] In one possible implementation, the adjustment assembly includes two adjustment frames and two sliding frames. The two adjustment frames are arranged one-to-one with the two first clamping hoops and are located on top of the first clamping hoops. The two sliding frames are arranged one-to-one within the two adjustment frames and are slidably connected to the adjustment frames in the vertical direction. The two ends of the adjustment roller are rotatably connected to the two sliding frames respectively.

[0007] In some embodiments, an adjusting screw is threadedly connected to the top of the adjusting frame. The adjusting screw passes through the top wall of the sliding frame and is rotatably connected to the sliding frame. The adjusting screw can rotate to drive the sliding frame to move up and down.

[0008] In some embodiments, the adjusting frame includes two uprights and a connecting plate. The two uprights are spaced apart on the top of the first clamping hoop and extend upward along a direction perpendicular to the main axis of the adjusting roller. The top of the uprights has a bent portion that bends outward. The connecting plate is disposed on the top of the uprights, and the adjusting screw is threadedly connected to the connecting plate. The connecting plate and the bent portion are connected by a locking member.

[0009] In some embodiments, a through groove extending to the outer edge is provided through the bent portion, and a limiting post located on one side of the through groove is provided at the bottom of the bent portion. The locking component includes a locking bolt and a locking sleeve. The locking bolt is provided through the connecting plate and the through groove. The locking sleeve is threaded onto the outer periphery of the locking bolt, and a limiting strip extending outward is connected to the outer peripheral wall of the locking sleeve. The locking bolt can rotate to drive the locking sleeve to rotate, and the limiting strip abuts against the outer peripheral wall of the limiting post to tighten the locking sleeve onto the locking bolt.

[0010] In some embodiments, the top of the stand is provided with a positioning groove, and the bottom of the connecting plate is provided with a positioning post that is inserted into the positioning groove.

[0011] In some embodiments, the adjusting screw is disposed downward through the top wall of the sliding frame, and a limiting platform protruding outward is provided on the lower outer peripheral wall of the adjusting screw, the limiting platform being used to abut against the inner top wall of the sliding frame.

[0012] In some embodiments, a handwheel is provided at the upper end of the adjusting screw.

[0013] Compared with the prior art, the fabric weft skew adjustment structure provided in this embodiment can be disassembled by simply loosening the connecting bolts and connecting nuts slightly and moving horizontally towards the openings of the first and second locking grooves (outside the first and second wing plates). This allows for the rapid disassembly of the first and second clamping hoops without the need to disassemble and separate the connecting nuts and connecting bolts, thus improving disassembly efficiency.

[0023] For ease of understanding, Figure 1 shows a general schematic diagram of frame 1 and a schematic diagram of the installation state of the fabric weft skew adjustment structure.

[0024] Please refer to Figures 1 to 4 for a description of the fabric weft skew adjustment structure provided by this utility model. The fabric weft skew adjustment structure includes two sets of clamping components 10 and an adjusting component 20. The two sets of clamping components 10 are respectively mounted on two opposing longitudinal beams 2 of the frame 1. Each set of clamping components 10 includes a first clamping hoop 11 and a second clamping hoop 12 clamping around the outer periphery of the longitudinal beam 2. The first clamping hoop 11 is located above the second clamping hoop 12. First wing plates 111 are provided on both sides of the first clamping hoop 11, and second wing plates 121 are provided on both sides of the second clamping hoop 12. The two first wing plates 111 and the two second wing plates 121 are arranged in a one-to-one correspondence. The outer edge of the first wing plate 111 is provided with an outward opening first locking groove 112, and the outer edge of the second wing plate 121 is provided with an outward opening second locking groove 122 that corresponds one-to-one with the first locking groove 112. The first wing plate 111 and the second wing plate 121 are connected by a bolt assembly 30 that passes through the first locking groove 112 and the second locking groove 122. The adjustment assembly 20 is provided on the two first clamping hoops 11, and the adjustment assembly 20 is rotatably connected to the adjustment roller 21 whose main shaft extends along the interval direction of the two sets of clamping assemblies 10, for adjusting the weft skew of the fabric 3.

[0025] Furthermore, the bolt assembly 30 includes a connecting bolt and a connecting nut that is threadedly connected to the connecting bolt.

[0026] This application provides a fabric weft skew adjustment structure. In actual use, the first clamping hoop 11 and the second clamping hoop 12 in each set of clamping components 10 are clamped onto the corresponding longitudinal beam 2 of the frame 1, the first wing plate 111 and the second wing plate 121 abut against each other, and the first locking groove 112 and the second locking groove 122 are aligned with each other. The rod of the connecting bolt passes through the first locking groove 112 and the second locking groove 122, and the head of the connecting bolt abuts against the top surface of the first wing plate 111. The connecting nut is threadedly connected to the connecting bolt and abuts against the bottom surface of the second wing plate 121, thereby connecting the first clamping hoop 11 and the second clamping hoop 12 together.

[0027] During disassembly, simply loosen the connecting bolts and nuts slightly and move horizontally towards the openings of the first locking groove 112 and the second locking groove 122 (outside the first wing plate 111 and the second wing plate 121) to complete the disassembly of the first clamping hoop 11 and the second clamping hoop 12. This achieves quick disassembly of the first clamping hoop 11 and the second clamping hoop 12 without the need to disassemble and separate the connecting nuts and connecting bolts, thus improving disassembly efficiency.

[0028] Compared with the prior art, the fabric weft skew adjustment structure provided in this embodiment can be disassembled by simply loosening the connecting bolts and connecting nuts slightly and moving horizontally towards the openings of the first locking groove 112 and the second locking groove 122 (outside the first wing plate 111 and the second wing plate 121). This allows for the quick disassembly of the first clamping hoop 11 and the second clamping hoop 12 without the need to disassemble and separate the connecting nuts and connecting bolts, thus improving disassembly efficiency.

[0029] In one possible implementation, the adjustment component 20 adopts the structure shown in Figures 1 to 4. Referring to Figures 1 to 4, the adjustment component 20 includes two adjustment frames 22 and two sliding frames 23. The two adjustment frames 22 are correspondingly arranged with the two first clamping hoops 11 and are located on top of the first clamping hoops 11. The two sliding frames 23 are correspondingly arranged in the two adjustment frames 22 and are slidably connected to the adjustment frames 22 in the vertical direction. The two ends of the adjustment roller 21 are rotatably connected to the two sliding frames 23 respectively.

[0030] Specifically, the sliding frame 23 is locked onto the adjusting frame 22 by an external auxiliary component. Since the weft skew adjustment is usually a fine adjustment (the angle deviation is generally less than 3°, and the adjustment range of this application is less than 3°), the influence of this small offset on the rotation of the adjusting roller 21 is negligible. When the fabric 3 is conveyed and weft skew occurs, one of the sliding frames 23 is moved up or down to make a fine adjustment, so that the fabric 3 is conveyed back to the correct position, thus realizing the rapid adjustment of the weft skew of the fabric 3.

[0031] Furthermore, the adjusting roller 21 and the sliding frame 23 are rotatably connected by a self-aligning roller bearing or a spherical bearing. The self-aligning roller bearing or spherical bearing allows the adjusting roller 21 to tilt within a certain angle range without increasing rotational resistance, thus avoiding jamming or wear due to skewness.

[0032] In some embodiments, referring to Figures 2 to 4, the top of the adjusting frame 22 is threadedly connected to an adjusting screw 24. The adjusting screw 24 is disposed downward through the top wall of the sliding frame 23 and is rotatably connected to the sliding frame 23. The adjusting screw 24 can rotate to drive the sliding frame 23 to move up and down.

[0033] Specifically, when the fabric 3 is conveyed and the weft skew occurs, the corresponding adjusting screw 24 is rotated to drive the corresponding sliding frame 23 to move up or down for fine adjustment, so that the fabric 3 is conveyed back to the correct position. After the adjustment is completed, the adjusting screw 24 can fix the adjusted position of the sliding frame 23 without the need for external auxiliary equipment to fix the position of the sliding frame 23, thus realizing the rapid adjustment of the weft skew of the fabric 3.

[0034] In some embodiments, referring to Figures 2 to 4, the adjusting frame 22 includes two uprights 221 and a connecting plate 223. The two uprights 221 are spaced apart on the top of the first clamping hoop 11 and extend upward along a direction perpendicular to the main axis of the adjusting roller 21. The top of the uprights 221 has a bent portion 222 that bends outward. The connecting plate 223 is disposed on the top of the uprights 221, and the adjusting screw 24 is threadedly connected to the connecting plate 223. The connecting plate 223 and the bent portion 222 are connected by a locking member 40.

[0035] Specifically, the two side walls of the sliding frame 23 are slidably connected to the two uprights 221 respectively, and the connecting plate 223 and the uprights 221 are detachable, which facilitates the disassembly and maintenance of the sliding frame 23 and improves convenience.

[0036] In some embodiments, referring to Figures 2 to 4, a through groove 224 extending to the outer edge is provided through the bent portion 222, and a limiting post 225 located on one side of the through groove 224 is provided at the bottom of the bent portion 222. The locking member 40 includes a locking bolt 41 and a locking sleeve 42. The locking bolt 41 is provided through the connecting plate 223 and the through groove 224. The locking sleeve 42 is threaded onto the outer periphery of the locking bolt 41, and a limiting strip 43 extending outward is connected to the outer peripheral wall of the locking sleeve 42. The locking bolt 41 can rotate to drive the locking sleeve 42 to rotate, and the limiting strip 43 abuts against the outer peripheral wall of the limiting post 225 so that the locking sleeve 42 is tightened onto the locking bolt 41.

[0037] Specifically, the through slot 224 allows the locking member 40 to pass through. When installing the connecting plate 223, the locking bolt 41 can be inserted into the preset hole of the connecting plate 223 in advance, and the locking sleeve 42 can be pre-tightened onto the locking bolt 41. Pick up the connecting plate 223, align the locking bolt 41 and the locking sleeve 42 and insert them into the through slot 224. When the locking sleeve 42 reaches the bottom of the bent part 222, rotate the locking bolt 41, and at the same time drive the locking sleeve 42 to rotate. After the limiting strip 43 abuts against the limiting post 225, the locking sleeve 42 stops rotating, and the locking bolt 41 continues to rotate. Thus, the locking sleeve 42 drives the limiting strip 43 to move upward and abut against the bottom surface of the bent part 222, realizing the quick locking between the connecting plate 223 and the bent part 222.

[0038] During disassembly, simply rotate the locking bolt 41 to make the limiting strip 43 rotate away from the limiting post 225. In the initial state of rotation, there is a certain compressive force between the limiting strip 43 and the bent part 222. The limiting strip 43 does not move initially, and the locking bolt 41 rotates, thereby causing the locking sleeve 42 to move down. When the compressive force decreases or disappears, the limiting strip 43 will rotate with the locking bolt 41 to the bottom of the through groove 224. Then, pull the connecting plate 223 upward to quickly disassemble.

[0039] In some embodiments, referring to Figures 3 and 4, the top of the stand 221 is provided with a positioning groove 226, and the bottom of the connecting plate 223 is provided with a positioning post 227 that is inserted into the positioning groove 226.

[0040] Specifically, when the connecting plate 223 needs to be installed on the stand 221, the positioning post 227 is aligned and inserted into the positioning slot 226 to achieve quick positioning of the connecting plate 223 and the stand 221, which facilitates the quick fixing of the locking part 40.

[0041] In some embodiments, referring to Figures 2 and 3, the adjusting screw 24 is disposed downward through the top wall of the sliding frame 23, and a limiting platform 241 protruding outward is provided on the lower outer peripheral wall of the adjusting screw 24. The limiting platform 241 is used to abut against the inner top wall of the sliding frame 23.

[0042] Specifically, the adjusting screw 24 is rotatably engaged with the sliding frame 23, and the limiting platform 241 is used to restrict the sliding frame 23 from disengaging from the adjusting screw 24, so as to facilitate its movement following the adjusting screw 24.

[0043] In some embodiments, referring to Figures 2 to 4, the upper end of the adjusting screw 24 is provided with a handwheel 242.

[0044] Specifically, the handwheel 242 is designed to facilitate the adjustment of the handwheel by the staff.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
