[0002] Textile waste edge, also known as false edge, waste edge, and discarded edge, refers to the fabric part on one or both sides of the fabric during shuttleless weaving, where the warp density and width outside the fabric edge are very small. After the fabric is formed, the textile waste edge usually needs to be cut off.

[0003] The Chinese patent with the publication number CN211665275U discloses a waste edge treatment device for an air-jet loom, which includes a frame. A cutter for cutting off the waste edge is arranged on the frame. A pressing device for pressing the fabric is arranged on the frame. The pressing device includes a first screw rod, a pressing plate for pressing the fabric against the fabric roller of the air-jet loom, and a limiting nut for limiting the pressing plate on the first screw rod. The first screw rod is fixedly connected to the frame, passes through the pressing plate and is threadedly connected with the limiting nut, and one end face of the limiting nut abuts against the pressing plate. By pressing the fabric with the pressing plate, the possibility of wrinkles is reduced, and to a certain extent, the waste edge is easier to be cut off, preventing the waste edge from remaining on the woven fabric and improving work efficiency.

[0004] Based on the above situation, the current inventor believes that the sizes of waste edges of different fabrics are different, and the position of the cutting knife is usually fixed on the loom, making it difficult to flexibly cut waste edges of different width sizes.

Specific embodiments

[0035] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] The embodiment of the present utility model specifically provides a waste edge treatment device for an air-jet loom. Please refer to Figure 1 , including a machine body 1 and a trimming component 2.

[0037] Among them, a conveying roller component 11 is rotatably installed on the machine body 1, and the trimming component 2 is arranged in the fabric output direction of the conveying roller component 11, so that after the fabric is processed and conveyed by the conveying roller component 11, the waste edge can be trimmed by the trimming component 2.

[0038] Specifically, the trimming component 2 includes an installation box 3, an adjusting frame 4, a cutting knife 5, a rotating cylinder 6, an adjusting cylinder 7 and a driving component. The outside of the installation box 3 is fixedly installed on the machine body 1 by embedding. The adjusting frame 4 is slidably arranged in the installation box 3, and one end of the adjusting frame 4 close to the conveying roller component 11 is fixedly connected to the cutting knife 5. The rotating cylinder 6 is rotatably installed on the installation box 3. The adjusting cylinder 7 is fixed to the outer wall of the rotating cylinder 6. The driving component is arranged inside the installation box 3. The position of the cutting knife 5 is adjusted by the driving component, so that the position of the cutting knife 5 can be matched with the width of the waste edge to be trimmed, meeting the trimming requirements for waste edges of different widths.

[0039] Furthermore, please refer to Figure 2 And Figure 3The interior of the installation box 3 is a hollow structure, and a sliding opening 31 is provided on one side of the installation box 3 close to the conveying roller member 11 , and the sliding opening 31 can provide stable support for the left and right movement of the adjustment frame 4 .

[0040] Specifically, the adjustment frame 4 includes a frame body 41 whose outer wall slides with the slide 31, and the outer end of the frame body 41 is fixedly connected to the cutter 5. The frame body 41 is a rectangular structure as a whole, and can slide left and right along the slide 31 after being thrust in the left and right directions, thereby driving the cutter 5 to adjust the left and right position and adjust the cutting position.

[0041] Among them, a screw hole 32 is opened on the side of the installation box 3 away from the conveying roller 11, and the rotating cylinder 6 includes a first cylinder body 61 whose outer wall is in rotational contact with the screw hole 32 and a limiting ring 62 fixed on the outer wall of the first cylinder body 61 at intervals. The connecting surfaces of the two limiting rings 62 are in rotational contact with the installation box 3. Due to the restriction of the limiting ring 62, the first cylinder body 61 can only be used for circumferential rotation in the screw hole 32, so as to provide installation support for the use of the adjustment cylinder 7 and the drive assembly.

[0042] During implementation, the outer diameter of the limiting ring 62 is larger than the inner diameter of the screw hole 32 , thereby preventing the first cylinder 61 from sliding left and right in the screw hole 32 , which is beneficial to the stable rotation of the first cylinder 61 .

[0043] Among them, the adjustment cylinder 7 includes a second cylinder 71 coaxially fixed with the limiting ring 62 on the outside and an anti-slip rod 72 fixed on the outer wall of the second cylinder 71. The limiting ring 62 located at the outer end of the first cylinder 61 is fixed to the second cylinder 71. Therefore, the second cylinder 71 is rotated by the anti-slip rod 72, which can drive the first cylinder 61 and the limiting ring 62 to rotate synchronously. The first cylinder 61 and the second cylinder 71 are both hollow structures open to the left and right, so as to facilitate the left and right movement of the frame 41 inside the first cylinder 61 and the second cylinder 71.

[0044] For further information, please refer to Figure 4 The driving assembly includes a worm tube 81 coaxially fixed with the limiting ring 62 on the outside, a worm wheel 82 meshing with the worm tube 81 on the periphery, a connecting piece rotatably arranged in the cavity of the installation box 3, a first gear 83 driven by the connecting piece and the worm wheel 82, and a second gear 84 meshing with the first gear 83 on the periphery. The worm tube 81 is fixed to the limiting ring 62 at the inner end of the first cylinder 61, and the worm tube 81 is a hollow tube with a worm wheel structure on the outside. After the first cylinder 61 rotates, it can drive the worm tube 81 to rotate, so that the worm tube 81 drives the worm wheel 82 to rotate, and through the hollow structure of the worm tube 81, the frame 41 can move in the left and right directions.

[0045] During implementation, due to the self-locking property of the worm and worm gear structure, the worm wheel 82 cannot reverse, thus ensuring the stability of the position setting of the cutting tool 5.

[0046] Among them, the worm wheel 82, the first gear 83, and the second gear 84 are all rotatably arranged in the cavity of the mounting box 3. The bottom side of the frame body 41 is provided with tooth grooves 42 at intervals along the length direction. The periphery of the second gear 84 meshes with the tooth grooves 42. When the worm wheel 82 rotates, it can drive the first gear 83 to rotate through the connecting member, so as to drive the second gear 84 to rotate, and the second gear 84 can push the frame body 41 to move linearly to the left or right through the tooth grooves 42, so as to quickly adjust the position of the cutting tool 5.

[0047] Specifically, a plurality of tooth blocks 85 are fixedly arranged on the outer peripheries of the worm wheel 82 and the first gear 83 in a circumferential array manner. The connecting member includes two bevel gears 86 whose outsides are respectively meshed with the worm wheel 82 and the first gear 83 through the tooth blocks 85 and a connecting rod 87 fixedly arranged coaxially with the two bevel gears 86. When the worm wheel 82 rotates, it can drive the bevel gears 86 to rotate through the tooth blocks 85, so that the bevel gears 86 transmit the driving force to the first gear 83 to drive the first gear 83 to rotate.

[0048] During implementation, a wheel frame 33 and a support frame 34 are fixedly installed in the cavity of the mounting box 3. The worm wheel 82, the first gear 83, and the second gear 84 are rotatably installed on the wheel frame 33, and the connecting rod 87 is rotatably installed on the support frame 34, so that they can all stably maintain rotation to ensure that the frame body 41 can move smoothly.

[0049] The control method of the present utility model is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the art, and the present utility model is mainly used to protect mechanical devices, so the control method and wiring layout of the present utility model will not be explained in detail.

[0050] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
