Description

Technical Field

[0001] This utility model relates to the field of arrow shaft loom technology, specifically an automatic edge trimming and waste collection device for arrow shaft looms. Background Technology

[0002] The rapier loom, also known as the shuttleless loom, is a type of loom whose core feature is the use of a pair of rigid or flexible rod / belt weft inserters (called rapiers) that enter the shed from both sides of the loom and interlock the weft yarn in the center to complete the weft insertion. This makes the weft insertion action active and reliable, especially good at handling low-strength and fancy yarns, and has excellent multi-color weft selection capability, width adaptability and wide variety of yarn types.

[0003] Because the loom uses double rapiers to introduce weft yarns and intersect them at the center of the weft insertion point, loose weft yarn ends are inevitably generated on both sides of the fabric width. However, these waste materials are rough and do not belong to the final fabric. They must be cut off after weaving to expose a clean and strong formal selvage (such as a folded-in edge) to meet the appearance and strength requirements of the finished product. For this reason, looms generally use cutting components such as fixed blade groups or rotating cutting wheels to cut the fabric edges and collect the waste generated by edge cutting through a collection box. This allows for efficient removal of waste generated by double rapier weft introduction and automatic waste recycling.

[0004] Existing looms can trim fabric edges and collect waste for centralized processing. When using these looms, different fabric widths are produced according to actual needs. Therefore, the distance between the two blades needs to be adjusted according to the fabric width. However, the blades are usually moved manually, which is time-consuming, labor-intensive, and makes it difficult to ensure adjustment accuracy and consistency. Furthermore, the two blades are driven by separate motors, making it difficult to ensure synchronization and resulting in poor fabric trimming stability. Therefore, this paper proposes an automatic trimming and waste collection device for arrow looms, which eliminates the drawbacks of existing devices. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] In one embodiment, such as Figures 1-5 As shown, an automatic edge trimming and waste collection device for a loom includes a support 1. A guide roller 8 is rotatably connected inside the support 1. Two blades 7 are symmetrically arranged inside the support 1, both of which are located below the guide roller 8.

[0039] The adjustment mechanism includes: two drive shafts 203 symmetrically arranged inside the bracket 1, two blades 7 respectively fixedly connected to the outer walls of the two drive shafts 203, two movable push plates 201 symmetrically arranged inside the bracket 1, the two movable push plates 201 respectively rotatably sleeved on the outer walls of the two drive shafts 203, and the two movable push plates 201 are slidably sleeved on the outer walls of the guide rollers 8.

[0040] In this embodiment, when in use, the fabric is wound up by the take-up roller 5.

Through the mutual cooperation between the racks 2011 and the second gear 2013, the two movable push plates 201 can be driven to move closer or further apart, thereby allowing for convenient adjustment of the distance between the two blades 7 according to the width of the fabric;

[0044] A rotating component is provided on bracket 1;

The outer wall of the limiting rotating cylinder 206 is integrally formed with a limiting rotating ring that is rotatably connected to the moving push plate 201. The inner walls of the two limiting rotating cylinders 206 are symmetrically formed with two limiting sliders. A linear slide groove for the limiting sliders to slide is opened at the position where the synchronous rotating rod 2010 connects with the limiting sliders.

[0049] A transmission assembly is provided on the limiting rotary drum 206;

[0050] The transmission assembly includes: a gear ring 205 fixedly connected to the outer wall of the limiting rotary cylinder 206, the gear ring 205 being located on the side of the movable push plate 201 away from the blade 7, the outer wall of the gear ring 205 being meshed with a first gear 204, the first gear 204 being fixedly connected to the transmission shaft 203, and through the mutual cooperation of the rotating assembly, the moving assembly and the transmission assembly, the two blades 7 after the spacing is adjusted can be driven to rotate synchronously;

[0051] In one embodiment, such as Figures 2-5 As shown, the tensioning assembly includes: a movable slider 209 slidably connected inside the movable push plate 201, the movable slider 209 being located below the guide roller 8, two fixed rods 207 being vertically and equidistantly fixed inside the movable push plate 201, the movable slider 209 being slidably sleeved on the outer wall of the two fixed rods 207, and two tensioning wheels 202 being symmetrically and rotatably connected to one side of the movable slider 209, both tensioning wheels 202 being located below the blade 7;

[0052] A reset assembly is provided on the fixing rod 207;

[0053] The reset component is a spring 208 sleeved on the outer wall of the fixed rod 207. One end of the spring 208 contacts the outer wall of the movable slider 209, and the other end of the spring 208 contacts the inner wall of the movable push plate 201. Through the cooperation of the tensioning component and the reset component, the tensioning effect on the edge of the fabric can be ensured, and the waste generated by the cutting edge can be guided and conveyed to the inside of the receiving box 9.

[0054] The above embodiment discloses an automatic edge trimming and waste collection device for arrow looms. In use, the fabric is wound up by the take-up roller 5. At this time, the auxiliary pressure roller 6 is used by the lifting component to squeeze the fabric wrapped on the outer wall of the take-up roller 5, thereby assisting the take-up roller 5 in winding the fabric. During this process, the fabric located inside the support 1 can be in a vertical state under the limiting of the guide roller 8 and the two conveying rollers.

[0055] Then, the servo motor 2012 is started to drive the second gear 2013 to rotate. At this time, the two racks 2011, driven by the meshing of the second gear 2013, drive the two movable push plates 201 to slide along the outer wall of the guide roller 8. At the same time, the blade 7 can be moved synchronously under the drive of the movable push plates 201 through the transmission shaft 203. At this time, the limiting cylinder 206, driven by the limiting ring under the drive of the movable push plate 201, slides along the inner wall of the straight slide groove through the limiting slider. At the same time, the two tensioning wheels 202 move synchronously under the drive of the movable push plate 201 through the movable slider 209 until the two blades 7 move to the two sides of the fabric respectively, and the edges of the fabric are clamped and limited by the two tensioning wheels 202. At this time, the movable slider 209, driven by the two tensioning wheels 202, slides along the outer wall of the fixed rod 207 and is contracted by the movable compression spring 208. This ensures the tension of the fabric, so that the distance between the two blades 7 can be easily adjusted according to the width of the fabric.

[0056] Then, the drive motor 2014 is started to drive the synchronous rotating rod 2010 to rotate. At this time, the limiting rotating cylinder 206 drives the gear ring 205 to rotate through the limiting slider driven by the synchronous rotating rod 2010. At the same time, the first gear 204 drives the blade 7 to rotate through the transmission shaft 203 under the meshing drive of the gear ring 205. In this way, the blade 7 can cut the edge of the fabric. At this time, the spring 208 can push the moving slider 209 to drive the two tensioning wheels 202 to move through the rebound. In this way, the two tensioning wheels 202 can ensure the tension effect of the fabric edge. At the same time, one tensioning wheel 202 drives the other tensioning wheel 202 to rotate through friction under the drive of the fabric. At this time, through the clamping and limiting of the two tensioning wheels 202, the waste can be guided and conveyed into the inside of the collection box 9, so that the waste can be collected conveniently for centralized processing.

[0057] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
