Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, and specifically relates to a device for preventing the tail of horizontally woven fabric from tilting. Background Technology

[0002] Knitting machines are common textile equipment that knit multiple warp threads into a patterned fabric and then wind it up. In the production of horizontally woven fabrics, the width of the fabric after knitting differs significantly from the width of the warp threads. This causes the finished fabric to shrink inwards, and the tension during winding makes it difficult to maintain a completely consistent width across the entire fabric width, resulting in a tighter center and looser edges. This leads to a slightly faster fabric speed in the center than at the edges, causing a twill weave defect in certain areas along the fabric edge, requiring cutting and resulting in problems such as fabric width discrepancies and increased production defect rates. Current production processes often increase the number of warp threads to ensure the final fabric width. While this method can guarantee the quality of the final product, it increases production costs and still does not solve the problem of high defect rates. Utility Model Content

[0003] The purpose of this invention is to propose a device to prevent tail skew in horizontally woven fabric, in order to solve the problem that the fabric edge forms a tail skew defect due to uneven control of winding tension during the production of horizontally woven fabric, which leads to defective finished products, increased costs, or a high rate of production defects.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a device to prevent the tail of a transverse woven fabric from tilting. The device is located on both sides of the fabric feed side of the tension adjusting roller during the winding of the transverse woven fabric, corresponding to the edge of the fabric. It includes a fixed rod parallel to the tension adjusting roller, with a mounting plate extending through the end of the fixed rod. The mounting plate is pear-shaped, with its smaller upper end connected to the fixed rod and its larger lower end equipped with a rotating shaft. An annular rolling element is mounted on the rotating shaft, and toothed spikes are evenly distributed on the rolling element. A protective cover is provided outside the rolling element and is fixedly mounted on the mounting plate. The protective cover has a semi-annular clearance groove corresponding to the rolling element. A guide rod is located below the protective cover, with a gap reserved between the guide rod and the rolling element for the transverse woven fabric to pass through.

[0006] Based on the above technical solution, by setting toothed rolling elements and guide rods on the feed side of the tension regulating roller for winding cross-grained fabric, the cross-grained fabric is first passed through the gap between the rolling elements and the guide rods after being woven. The toothed elements grab and fix the edge of the cross-grained fabric to adjust the width of the fabric, so that the cross-grained fabric on the fabric is kept horizontal before entering the tension regulating roller. Then, under the pulling force of the tension regulating roller, it is conveyed forward to the winding roller, so that the edge of the wound fabric is kept horizontal with cross-grained pattern. This achieves the purpose of preventing the formation of tail slant defects, effectively improving production yield and weaving quality.

[0007] Preferably, the rotating shaft and the protective cover are eccentrically positioned, and the opening of the clearance groove faces the winding direction of the cross-woven fabric. This design, through the eccentric rotating shaft and the protective cover, together with the guide rod, forms a guiding and protective function for adjusting the width of the cross-woven fabric, so that the toothed nail can effectively grab the edge of the cross-woven fabric, while also helping to prevent the cross-woven fabric from contacting the toothed nail too early, which would cause damage to the winding rolling parts.

[0008] Preferably, multiple rolling elements are provided, and multiple clearance grooves are also provided accordingly. Only one rolling element is provided in each clearance groove. This design forms mutual isolation and limiting of the rolling elements, so that the rolling elements form multiple width adjustment zones for the transverse fabric along the winding direction. This can not only ensure the anti-tail skewing effect, but also minimize the cumulative force of the toothed nail on the transverse fabric texture, which is more conducive to the self-repair of the texture after winding.

[0009] More preferably, the teeth on the rolling element are staggered to avoid the teeth on the rolling element acting on the same horizontal rib or weaving warp simultaneously when the rolling element rotates. This can reduce the risk of tearing damage to the rib and avoid the phenomenon of intermittent gripping and releasing of the horizontal rib fabric by the teeth, which would cause uneven stress on the same weaving warp of the horizontal rib fabric and breakage.

[0010] Preferably, a first adjustment component is provided between the mounting plate and the fixing rod. The adjustment component includes a first toothed ring on the fixing rod and a first toothed groove on the mounting plate. The first toothed ring and the first toothed groove are configured to cooperate with each other. This design facilitates the overall adjustment of the mounting angle of the mounting plate and its components, so that the rolling element can better adapt to the width angle of the cross-woven fabric, so that the cross-woven fabric can pass smoothly through the guide rod without generating additional amplitude, thus avoiding affecting the winding tension control.

[0011] Preferably, the end of the fixing rod is provided with a pressing rod extending toward the cross-grained fabric. The pressing rod includes a connecting part and a pressing part. The connecting part connects the fixing rod and the pressing part. The pressing part is arranged parallel to the cross-grained fabric and conforms to the cross-grained fabric forming position. The purpose of this design is to ensure that once the cross-grained fabric is woven, it is kept horizontally conveyed downward under the limiting action of the pressing rod, and after being readjusted by the rolling element, it enters the tension regulating rollers. This ensures that the cross-grained fabric edge pattern remains horizontal during winding, further reducing the risk of tail slant.

[0012] More preferably, the fixed rod extends to an extension rod, and the mounting plate is provided with an adjustment seat corresponding to the extension rod. The pressing rod is fixedly mounted on the adjustment seat, and a second adjustment component is provided between the adjustment seat and the extension rod. The second adjustment component includes a second toothed ring and a second toothed groove that cooperate with each other. The second toothed ring is located on the extension rod, and the second toothed groove is located on the adjustment seat. This design adjusts the pressing angle of the pressing rod through the second adjustment component to better fit the conveying angle of the formed cross-woven fabric.

[0013] More preferably, the pressing rod is movably adjustable with the adjusting seat. The adjusting seat has a first through hole and a second through hole. The connecting part of the pressing rod passes through and slides in the first through hole. A locking bolt passes through the second through hole. The end of the locking bolt abuts against the connecting part to fix it. This design allows the length of the pressing rod to be adjusted relative to the cross-woven fabric, ensuring that the fit and adhesion force between the pressing rod and the cross-woven fabric meet the preset requirements.

[0014] More preferably, the end of the fixing rod extends to provide a threaded rod, on which a pair of washers and a fastening bolt are provided. The end of the connecting part of the pressing rod forms an open ring, which is then locked and fixed by the fastening bolt after being embedded between the washers. This design simplifies the adjustment structure of the pressing rod and makes it easier to operate.

[0015] Beneficial effects

[0016] One of the above technical solutions has the following advantages or beneficial effects:

[0017] 1) To address the unavoidable problem of skewed edges at the seams during the production of cross-ribbed fabrics, a rolling element with toothed pins and a guide rod corresponding to the edge of the cross-ribbed fabric are installed on the feed side of the tension regulating roller during the winding of the cross-ribbed fabric. After the cross-ribbed fabric is woven, it first passes through the gap between the rolling element and the guide rod. The toothed pins grasp and fix the edge of the cross-ribbed fabric, adjusting the fabric width and keeping the cross-ribbed fabric horizontal before entering the tension regulating roller. Then, under the pulling force of the tension regulating roller, it is conveyed forward to the winding roller, ensuring that the edge of the wound fabric remains horizontal with cross-ribbed edges. This achieves the purpose of preventing skewed edges, effectively improving production yield and weaving quality. Moreover, the entire device has a simple structure, is easy to install and fix, and will not interfere with the operation of existing equipment components, making it particularly suitable for the improvement of existing knitting equipment.

[0018] 2) To address the issue that when the rolling element and its toothed pins act on the tensioned cross-ribbed fabric, it is difficult to avoid causing significant vertical tension on the warp threads, resulting in damage to the fabric edges, a pressure bar is installed at the end of the fixed rod. This pressure bar presses the cross-ribbed fabric at the knitting forming position, maintaining the width before forming. Once the cross-ribbed fabric is woven, it is kept horizontally conveyed downwards under the limiting action of the pressure bar, allowing the cross-ribbed fabric to slowly converge. After being conveyed to the rolling element, it is readjusted and then enters the tension regulating rollers. This ensures that the cross-ribbed fabric edges remain horizontal throughout the entire process from forming to winding, further reducing the probability of tail slant and improving production yield.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0027] Example 1

[0028] like Figure 1 As shown, this embodiment provides a device for preventing the tail of a cross-woven fabric from tilting, which is installed on both sides of the feed side of the tension adjusting roller 200 of the winding cross-woven fabric 100, corresponding to the edge of the cross-woven fabric 100. Figure 2 , Figure 3 As shown, the anti-tail tilting device of this embodiment includes a fixed rod 1 parallel to the tension adjusting roller 200. One end of the fixed rod 1 can be fixed to the existing support structure of the equipment (not shown in the figure). The end of the fixed rod 1 is provided with a mounting plate 2. The mounting plate 2 is pear-shaped. The smaller upper end of the mounting plate 2 is connected to the fixed rod 1. The larger lower end of the mounting plate 2 is provided with a rotating shaft 3. The rotating shaft 3 is provided with an annular rolling element 4. The rolling element 4 is evenly distributed with toothed nails 5.

[0029] The rolling element 4 is provided with a protective cover 6, which is fixedly installed on the mounting plate 2. The protective cover 6 has a semi-circular clearance groove 7 corresponding to the rolling element 4. Preferably, the rotating shaft 3 is eccentrically positioned with respect to the protective cover 6, and the opening of the clearance groove 7 faces the winding direction of the cross-woven fabric 100 to achieve the effects of guidance and anti-winding. A guide rod 8 is provided below the protective cover 6. A gap is reserved between the guide rod 8 and the rolling element 4 for the cross-woven fabric 100 to pass through. The toothed nail 5 is provided to fill the gap and is used to grip and release the cross-woven fabric 100 to achieve the effects of adjusting the fabric width and keeping the weave horizontal.

[0030] Preferably, multiple rolling elements 4 are provided, and multiple clearance grooves 7 are also provided accordingly. Only one rolling element 4 is provided in each clearance groove 7 to isolate and limit the rolling elements 4 from each other, forming multiple width adjustment zones for the cross-weave fabric 100, reducing the cumulative damage caused by the force exerted by the toothed nail 5 on the weave of the cross-weave fabric 100. More preferably, as Figure 4As shown, the toothed spikes 5 on the rolling element 4 are staggered to avoid the toothed spikes 5 on the rolling element 4 acting on the same horizontal pattern or weaving warp when the rolling element 4 rotates, and the intermittent grabbing and releasing of the horizontal patterned fabric 100 by the toothed spikes 5 due to the distribution gap, thereby avoiding the horizontal patterned fabric 100 from being damaged by the device of this utility model.

[0031] Furthermore, referring to Figure 3 As shown, a first adjusting component 9 is provided between the mounting plate 2 and the fixing rod 1. The adjusting component includes a first toothed ring 901 on the fixing rod 1 and a first toothed groove 902 on the mounting plate 2. The first toothed ring 901 and the first toothed groove 902 are arranged in cooperation with each other so that the mounting plate 2 and its components can be adjusted as a whole to accommodate the different winding width angles of the cross-woven fabric 100 produced by different machine models. This allows the cross-woven fabric 100 to pass smoothly through the guide rod 8 without additional bending, thus avoiding affecting the winding tension control.

[0032] Furthermore, referring to Figure 1 The fixed rod 1 has a pressing rod 10 extending towards the cross-ribbed fabric 100 at its end. The pressing rod 10 includes a connecting part 1001 and a pressing part 1002. The connecting part 1001 connects the fixed rod 1 and the pressing part 1002. The pressing part 1002 is arranged parallel to the cross-ribbed fabric 100 and is set in contact with the forming position of the cross-ribbed fabric 100, that is, parallel to the end of the knitting needle of the knitting part 300 in the previous process. This ensures that once the cross-ribbed fabric 100 is knitted, it is kept horizontally conveyed downward under the limiting action of the pressing rod 10. After being adjusted again by the rolling element 4, it enters the tension regulating roller 200, which ensures that the pattern at the edge of the cross-ribbed fabric 100 remains horizontal during winding, further reducing the risk of tail twill.

[0033] Preferably, the pressing rod 10 and the fixing rod 1 are adjustable. Specifically, the fixing rod 1 has an extension rod 11 extending from its end. The mounting plate 2 has an adjustment seat 12 corresponding to the extension rod 11. The pressing rod 10 is fixedly mounted on the adjustment seat 12. A second adjustment component 13 is provided between the adjustment seat 12 and the extension rod 11. The second adjustment component 13 includes a second toothed ring 1301 and a second toothed groove 1302 that cooperate with each other. The second toothed ring 1301 is located on the extension rod 11, and the second toothed groove 1302 is located on the adjustment seat 12. The adjusting seat 12 has a first through hole 1201 and a second through hole 1202. The connecting part 1001 of the pressing rod 10 passes through and slides in the first through hole 1201. A locking bolt 1203 passes through the second through hole 1202. The end of the locking bolt 1203 abuts against the connecting part 1001 to fix it, so that the pressing rod 10 can be adjusted in angle and length relative to the cross-woven fabric 100, ensuring that the pressing rod 10 and the cross-woven fabric 100 are closely fitted, thereby effectively limiting the width of the cross-woven fabric 100.

[0034] Example 2

[0035] This embodiment provides a transverse weave fabric anti-tail tilting device, which differs from Embodiment 1 in that:

[0036] like Figure 5 As shown, the adjustable structure between the pressing rod 10 and the fixing rod 1 is as follows: the end of the fixing rod 1 extends with a threaded rod 14, the threaded rod 14 is provided with a pair of washers 15 and a fastening bolt 16, the end of the connecting part 1001 of the pressing rod 10 forms an open ring 1003, the open ring 1003 is embedded between the washers 15 and then locked and fixed by the fastening bolt 16, the open ring 1003 can be set as a long strip to meet the synchronous adjustment of angle and length.

[0037] The advantage of this embodiment is that the adjustable structure between the pressing rod 10 and the fixing rod 1 is simpler, easier to operate, and more suitable for rapid assembly and adjustment on the production site.

[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
