Description

Technical Field

[0001] This utility model relates to the field of weaving device technology, and in particular to a weaving device with adjustable fabric width. Background Technology

[0002] Woven fabric weaving equipment is a type of machinery used to produce woven fabrics such as woven bags, geotextiles, and packaging materials. Its core function is to form fabrics with specific structures through the interlacing of warp and weft yarns. Depending on the process, common equipment includes circular knitting machines and flat knitting machines. The width of the woven fabric is determined by the warp yarn arrangement density and the mechanical structure of the equipment. By changing the unfolding angle or spacing of the spreader (spreading roller), the width of the fabric surface is directly affected. Adjusting the lateral density of the needle plate (reed) at the entrance of the weaving area controls the density of the warp yarn distribution.

[0003] Chinese patent discloses a weaving device for producing ton bag base fabric (authorization announcement number CN222666182U). This patented technology includes a first device housing, a circular loom, a thread guide frame, a bobbin frame, and a dust collection box. The circular loom is installed inside the first device housing. A second device housing is fixed to one side of the first device housing. The thread guide frame and bobbin frame are both installed inside the second device housing. A dust collection box is installed inside the second device housing on the side of the thread guide frame away from the bobbin frame. A lower brush and an upper brush are respectively installed at the bottom and top of the dust collection box. The dust collection box is installed at the top of the second device housing, and a blower is installed on one side of the dust collection box. A dust filter plate is installed inside the dust collection box. This invention facilitates the collection and treatment of broken threads, dust, and lint generated during the weaving process, and also facilitates the compression of broken threads, dust, and lint into sheets for easy cleaning.

[0004] This patented technology has the advantage of facilitating the removal of foreign objects during use, but it still has shortcomings. When the width of the woven fabric is adjusted, the conveying rollers supporting the woven fabric are limited on both sides by the limiting rings on the outer wall. However, the limiting rings are mostly fixed, and their position and size cannot be changed in real time according to the width adjustment of the woven fabric. When the width of the woven fabric is adjusted, the limiting rings may not be able to effectively limit the two sides of the woven fabric, resulting in problems such as displacement, shaking or wrinkling of the woven fabric during the conveying process. Therefore, those skilled in the art have provided a weaving device with adjustable fabric width to solve the problems mentioned in the background art. Utility Model Content

[0018] 2. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] This invention involves conveying woven fabric between a pressure roller and a conveying roller using a weaving device. During conveying, both ends of the woven fabric are limited by limiting rings. The position of the limiting rings is adjusted by rotating the screw through the threaded engagement with the screw hole, adapting to the conveying of woven fabrics of different widths. As the woven fabric passes through the conveying roller, the suction force of the negative pressure pump acts on the passing woven fabric through the gap between the through hole and the supporting mesh cylinder, causing the lower end of the woven fabric to be adsorbed and positioned, reducing the probability of deviation, shaking, or wrinkling during conveying. The adjustable fabric width weaving device improves the stability and flexibility during the conveying of woven fabric.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0034] Example 1

[0035] Please see Figures 1-5 As shown, this embodiment is a weaving device with adjustable fabric width, including a mounting frame 1, a fixing plate 5, a conveying roller 8 and a negative pressure pump 9. The conveying roller 8 is rotatably mounted inside the mounting frame 1. The conveying roller 8 is sleeved on the outside of the conveying roller 8 with symmetrically distributed limiting rings 3. Each limiting ring 3 has a sliding sleeve 14 embedded inside. The mounting frame 1 is provided with a guide rod 10 that is slidably mounted inside the sliding sleeve 14. Each limiting ring 3 has a screw hole 18. The mounting frame 1 is rotatably mounted with a screw 12 whose outer wall threads are relatively distributed. One end of the screw 12 is provided with a handle 13.

[0036] Mounting bracket 1 has brackets 2 on both sides of the upper end, and mounting holes are opened inside the brackets 2.

[0037] Mounting frame 1 has fixing plates 5 at both ends. The fixing plates 5 have symmetrically distributed springs 20 at the lower end. The springs 20 have mounting frames 6 at the lower end. The mounting frames 6 have pressure rollers 7 rotatably mounted inside the mounting frames 6. The upper outer wall of the conveying roller 8 and the lower outer wall of the pressure roller 7 are covered with woven fabric 4.

[0038] The upper end of the mounting frame 6 is provided with a guide rod 19, and the fixed plate 5 is embedded with symmetrically distributed sliding sleeves 21. The guide rod 19 is slidably installed inside the sliding sleeves 21.

[0039] In this embodiment, the mounting frame 1 is fixed to one end of the weaving device by the bracket 2. When using a weaving device with adjustable fabric width, the woven fabric is first placed between the pressure roller 7 and the conveying roller 8 for conveying. During the conveying process, the two ends of the woven fabric are limited by the limiting ring 3 sleeved on the outside of the conveying roller 8 to ensure that the woven fabric maintains the correct position and orientation during the conveying process.

[0040] The device has symmetrically distributed limiting rings 3 sleeved on the outer side of the conveying roller 8. The limiting rings 3 slide on the outer wall of the guide rod 10 through the sliding sleeve to obtain sliding guidance. The gripping handle 13 drives the screw 12 to rotate. When the screw 12 rotates, it passes through the threads distributed on the outer wall of the screw 12. Due to the threaded engagement between the screw 12 and the screw hole 18, the limiting rings 3 are pushed to move relative to or away from each other, thereby realizing the position adjustment of the limiting rings 3, so that the limiting rings 3 can be adapted to woven fabrics of different widths.

[0041] Example 2

[0042] Please see Figures 1-5 As shown, this embodiment is based on embodiment 1 and further includes: through holes 17 evenly distributed on the outer wall of the conveying roller 8; a negative pressure pump 9 is provided at one end of the mounting frame 1; a bearing 15 is embedded in the interior of one end of the conveying roller 8; and a suction pipe 16 is rotatably installed inside the bearing 15 at the suction end of the negative pressure pump 9.

[0043] A cylindrical support mesh 11 is sleeved on the outer wall of the conveying roller 8, and a limiting ring 3 is sleeved on the outside of the support mesh 11.

[0044] In this embodiment, the outer wall of the conveying roller 8 is provided with equally spaced through holes 17. One end of the mounting frame 1 is provided with a negative pressure pump 9. The suction end of the negative pressure pump 9 is provided with a suction pipe 16 rotatably installed inside the bearing 15. During the rotation of the conveying roller 8, the suction force of the negative pressure pump 9 can be applied to the outside of the conveying roller 8 through the through holes 17 by the rotational installation of the suction pipe 16 and the bearing 15. At the same time, a cylindrical support mesh 11 is also sleeved on the outer wall of the conveying roller 8. The limiting ring 3 is sleeved on the outside of the support mesh 11. During use, the support mesh 11 not only supports the outer wall of the conveying roller 8, but also allows air to circulate effectively through its internal gaps, thereby improving the adsorption effect of the negative pressure pump 9 on the woven fabric.

[0045] During the conveying process, the woven fabric 4 passes between the pressure roller 7 and the conveying roller 8 through components such as the fixing plate 5, spring 20, mounting frame 6 and pressure roller 7. The fixing plate 5 supports the mounting frame 6 through the spring 20, so that the woven fabric 4 is elastically pressed during the conveying process, maintaining the tension of the woven fabric 4 and preventing excessive stretching or loosening of the woven fabric 4 when it is over-tensioned or slack, thus ensuring the stability of the woven fabric 4 during the conveying process.

[0046] This adjustable-width weaving device adapts to different widths of woven fabric by adjusting the position of the limiting ring 3, and uses the suction force of the negative pressure pump 9 to adsorb and position the woven fabric, reducing the probability of the woven fabric shifting, shaking, or wrinkling during transportation. At the same time, the device also maintains the tension of the woven fabric through elastic compression, further improving the stability of transportation. It not only improves the stability and flexibility of the transportation process, but also solves the problem that the limiting ring 3 cannot effectively restrict the woven fabric after the width of the traditional weaving device is adjusted.

[0047] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
