Description

Technical Field

[0001] This utility model relates to the field of loom technology, and in particular to a waste yarn shearing and recycling device for air-jet looms. Background Technology

[0002] Air-jet looms use compressed air jets to pull the weft yarn through the shed. The biggest advantages of air-jet looms are high speed and high labor productivity, making them suitable for the production of plain and textured fabrics, fine and high-density fabrics, and large-volume fabrics.

[0003] During the production process, a large amount of waste yarn is generated. In order to improve resource utilization, the waste yarn needs to be recycled. During the recycling process, the waste yarn needs to be carefully sorted and screened to remove impurities and poor-quality parts to ensure the smooth operation of subsequent shredding and product quality. When the waste yarn enters the cutting equipment, the cutting parameters are precisely set according to different yarn characteristics and subsequent production needs to ensure that each yarn is shredded just right. After being shredded, the yarn can be mixed more evenly with various raw materials.

[0004] In existing technologies, waste yarn is mostly placed manually onto a conveyor belt, which then transports it to the cutting equipment. The waste yarn is cut by the cooperation of the cutting blade and the pad. The cut waste yarn then slides down under the action of the inclined guide plate. However, sometimes the cut waste yarn cannot fall onto the inclined guide plate in time and may accumulate near the pad, affecting the efficiency of subsequent cutting. Utility Model Content

[0005] The purpose of this invention is to provide a waste yarn shearing and recycling device for air-jet looms in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a waste yarn shearing and recycling device for an air-jet loom includes a cutting box 1. One side of the cutting box 1 is bolted with an inclined guide plate 101. The other side of the cutting box 1 is provided with a conveying assembly. The conveying assembly includes a mounting frame 201 fixedly connected to one side of the cutting box 1. A conveyor belt 202 is rotatably connected between the mounting frames 201. The upper surface of the conveyor belt 202 is at the same level as the inner bottom wall of the cutting box 1. The conveyor belt 202 is prior art and will not be described in detail. A sealing plate is fixedly connected to one side of the cutting box 1, close to the conveyor belt 202. The sealing plate seals the gap between the conveyor belt 202 and the cutting box 1 to prevent waste yarn from getting stuck in the gap.

[0027] The cutting box 1 is equipped with a cutting assembly, which includes a hydraulic cylinder 401 fixedly connected to the top wall of the cutting box 1. A horizontal plate 402 is fixedly connected to the bottom of the hydraulic cylinder 401, and a cutting blade 403 is fixedly connected to the bottom of the horizontal plate 402.

[0028] An extrusion assembly is provided between the cutting assembly and the conveying assembly. The extrusion assembly includes a rotary motor 301 bolted to the rear side of the cutting box 1. The output end of the rotary motor 301 is connected to an extrusion roller 302 via a coupling. The extrusion roller 302 is rotatably connected between the front and rear inner walls of the cutting box 1. The rotary motor 301 drives the extrusion roller 302 to rotate, which simply compacts the waste yarn, making it easier for subsequent cutting.

[0029] A material-pushing mechanism is provided between the cutting assembly and the guide plate 101. The material-pushing mechanism includes a mounting shaft 501 rotatably connected between the front and rear inner walls of the cutting box 1. A paddle 502 is fixedly connected to the outside of the mounting shaft 501. In the initial state, the paddle 502 is located above the mounting shaft 501. The mounting shaft 501 rotates 360 degrees each time to ensure that the horizontal plate 402 does not interfere with the paddle 502 when it moves up and down.

[0030] The feeding mechanism also includes a linkage component, which drives the mounting shaft 501 to rotate the paddle 502, thereby feeding the cut waste yarn. The linkage component includes a rack 503 fixedly connected to the top of the horizontal plate 402. A rotating shaft 504 is rotatably connected to the inner rear wall of the cutting box 1. A first gear 505 is fixedly connected to the rotating shaft 504. The first gear 505 meshes with the rack 503. The teeth on both the rack 503 and the first gear 505 are composed of arc-shaped segments and straight segments. The teeth on the rack 503 are movably connected to a mounting groove opened on one side of the rack 503 by a spring. When the rack 503 moves downward, the arc-shaped segments of the teeth on the rack 503 and the rotating shaft 504 engage. When the teeth are squeezed by the first gear 505, they contract inward. When the rack 503 moves upward, the straight segments of the teeth on the rack 503 and the rotating shaft 504 engage, and the rack 503 drives the first gear 505 to rotate. Therefore, when the rack 503 moves upward, it drives the first gear 505 to rotate. When the rack 503 moves downward, it does not drive the first gear 505 to rotate. The rear side of the cutting box 1 is rotatably connected to the drive shaft 506. The rear end of the rotating shaft 504 extends out of the cutting box 1. The rotating shaft 504 and the drive shaft 506 are both fixedly connected to the second gear 507. The two second gears 507 are the same size and mesh with each other. The drive shaft 506 and the mounting shaft 501 are connected by a synchronous belt 508 through a pulley.

[0031] Working principle: In use, waste yarn is placed on conveyor belt 202, which transports it to cutting box 1. Rotary motor 301 is started, driving the compression roller 302 to rotate, providing simple compression to the waste yarn for easier cutting later. Hydraulic cylinder 401 drives horizontal plate 402 to move the cutting blade 403 downwards, cutting the waste yarn. After cutting, hydraulic cylinder 401 drives horizontal plate 402 to move the cutting blade 403 upwards, simultaneously driving rack 503 to move upwards. The rack 503 meshes with the first gear 505, thereby driving the first gear 505 to rotate the rotating shaft 504. Through the meshing transmission between the two second gears 507, the transmission shaft 506 is driven to rotate. Through the transmission between the pulley and the synchronous belt 508, the mounting shaft 501 is driven to rotate the paddle 502 360 degrees. The paddle 502 pushes the cut waste yarn toward the guide plate 101, so that the waste yarn falls onto the guide plate 101 and then falls under the guidance of the guide plate 101, avoiding the accumulation of cut waste yarn near the cutting assembly and affecting subsequent cutting.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
