Description

Technical Field

[0001] This utility model relates to the field of loom auxiliary components technology, and in particular to a device for eliminating waste edges on the inner side of a rapier loom. Background Technology

[0002] A rapier loom is a shuttleless loom that uses a rapier as a weft feeder. The rapier head holds the weft yarn, causing it to be released from the weft feeder and pass through the shed.

[0003] Currently, when using rapier looms, if the weft yarn drawn from the weft bobbin and the selvage warp drawn from the selvage bobbin do not interweave properly, defects such as frayed edges, or waste edges, are easily formed. Currently, waste edges are mostly collected by suction using a fan. For example, a publicly available technical solution, announcement number [number missing], describes a rapier loom with a waste-edge-free suction structure, including a rapier loom body and a collection box. Stretching fabric is fixedly connected between the connecting rods, and a feed inlet is opened at the bottom of the stretching fabric. When workers cut the waste edges of the non-woven fabric, the waste edges fall between the stretching fabrics, and the fan suctions the waste edges in the feed inlet and collects them into the collection box. This achieves unified recycling and treatment, reducing environmental pollution. Furthermore, the suction power of the fan is higher and stronger.

[0004] In actual implementation of the above technical solution, the waste selvage falls into the collection box after being stretched by the fabric. The waste selvage yarn of the bar loom is usually in the form of continuous long strips. In order to save energy, most of the waste selvage yarn is currently recycled into recycled fibers. Since the crushed waste selvage yarn is more conducive to subsequent opening and mixing, the existing collection box has a simple structure and cannot crush the waste selvage. During recycling, the complete long strips of waste selvage yarn in the collection box need to be taken out and then transferred to the crushing device for crushing, which is inconvenient. Summary of the Invention

[0005] The purpose of this utility model is to provide a device for eliminating waste selvage on the inner side of a rapier loom. By adding a crushing component inside the collection box, the crushing component can break long strips of waste selvage into short fibers of 5-10cm under the action of crushing blades, which facilitates the subsequent recycling of waste selvage.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A device for eliminating waste edges inside a rapier loom includes a collection box assembly 1, a pipe assembly 4 for waste edge entry is provided on the top of the collection box assembly 1, and a crushing assembly 2 is installed inside the collection box assembly 1.

[0028] The crushing component 2 includes a servo motor 201 fixed to the side of the collection box component 1. A crushing shaft 202 is fixed to the power output end of the servo motor 201. A plurality of equidistant and evenly distributed crushing blades 204 are fixed around the crushing shaft 202.

[0029] The collection box assembly 1 includes a collection box body 101 with a cylindrical inner cavity. The inner cavity of the collection box body 101 coincides with the axis of the crushing shaft 202. A support rod 203 is fixed in the middle of the crushing shaft 202, and an arc-shaped scraper 205 is fixed at the end of the support rod 203. The arc-shaped scraper 205 fits against the inner wall of the collection box body 101, and the length of the arc-shaped scraper 205 is adapted to the length of the inner cavity of the collection box body 101. A door assembly 3 is installed on the lower front side of the collection box body 101.

[0030] The door assembly 3 includes a first door 301 slidably installed on the lower front side of the collection box body 101, and a second door 302 slidably connected to the inner side of the first door 301. Guide sliders 305 are fixed to the top of both the second door 302 and the first door 301. The second door 302 and the first door 301 are slidably installed on the front end of the collection box body 101 via the guide sliders 305. Handles 304 are bolted to the front end of the second door 302 and the first door 301. Iron blocks 306 are bolted to the side of the second door 302 and the first door 301 near the handles 304. Magnets 303 that magnetically attract the iron blocks 306 are embedded in the inner side of the collection box body 101.

[0031] By adopting the above technical solution, after the long strips of waste yarn enter the collection box 101, the servo motor 201 can be activated. The servo motor 201 drives the crushing shaft 202 to rotate, and the crushing blades 204 on the crushing shaft 202 can crush the long strips of waste yarn, breaking them into short fibers of 5-10cm. When it is necessary to discharge the material, the first compartment door 301 or the second compartment door 302 can be slid to separate the iron block 306 on the first compartment door 301 or the second compartment door 302 from the magnet 303. The guide slider 305 on the first compartment door 301 or the second compartment door 302 slides inside the collection box 101. After opening, the waste yarn can be discharged. The waste yarn can be removed from the first door 301 or the second door 302. During material removal, the crushing shaft 202 can drive the arc-shaped scraper 205 to rotate through the support rod 203. The arc-shaped scraper 205 scrapes the waste yarn adhering to the inner wall of the collection box 101 to the first door 301 or the second door 302 for easy discharge. By adding a crushing component 2 inside the collection box 101, the crushing component 2 can break the long strips of waste yarn into short fibers of 5-10cm under the action of the crushing blades 204, which facilitates the subsequent recycling of waste yarn. The waste yarn can be pre-crushed when collecting waste yarn, saving time and making it convenient to use.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the collection box assembly 1 also includes a filter cover 102 that communicates with the collection box body 101, and a filter screen 106 is provided inside the filter cover 102. A suction pipe 103 is fixed to the end of the filter cover 102, and a fan 105 is fixedly connected to the end of the suction pipe 103. An exhaust pipe 104 for exhausting air is fixedly connected to one side of the fan 105. The pipe assembly 4 includes a flexible hose 401 that is disposed on the top of the collection box body 101 and communicates with the collection box body 101. A first connecting pipe 402 is connected to the end of the flexible hose 401, and a reducing connector 403 is connected to the end of the first connecting pipe 402. A first bend 404 is connected to the end of the reducing connector 403, and a second connecting pipe 405 is connected to the end of the first bend 404. A second bend 406 is connected to the end of the second connecting pipe 405.

[0033] By adopting the above technical solution, before the blower 105 starts working, one end of the long strip of waste yarn is inserted into the second bend pipe 406 and then into the second connecting pipe 405. Then the blower 105 is started, and the blower 105 can suck in the long strip of waste yarn. The long strip of waste yarn can enter the first bend pipe 404 through the second connecting pipe 405, and then enter the collection box 101 through the hose 401 under the action of the first connecting pipe 402. The filter screen 106 set in the filter cover 102 can prevent short fibers from entering the filter cover 102 and affecting the normal use of the blower 105. Through the set pipe assembly 4, the long strip of waste yarn is conveniently introduced into the collection box 101, so that the waste yarn can be processed through the collection box 101.

[0034] Working principle: The collection box assembly 1 is installed inside the rapier loom. The second bend 406 on the pipe assembly 4 matches the height of the scissors on the rapier loom. Before the blower 105 starts, one end of the long strip of waste selvage is inserted into the second bend 406 and then into the second connecting pipe 405. The blower 105 is then started, which sucks in the long strip of waste selvage. The long strip of waste selvage can enter the first bend 404 through the second connecting pipe 405, and then enter the collection box 101 through the hose 401 under the action of the first connecting pipe 402. After the long strip of waste selvage enters the collection box 101, the servo motor 201 can be started. The servo motor 201 drives the crushing shaft 202 to rotate, and the crushing blades 204 on the crushing shaft 202 crush the long strip of waste selvage, breaking it into 5-10 pieces. For short fibers of cm, when discharge is required, the first compartment door 301 or the second compartment door 302 can be slid to separate the iron block 306 on the first compartment door 301 or the second compartment door 302 from the magnet 303. The guide slider 305 on the first compartment door 301 or the second compartment door 302 slides inside the collection box 101. After opening, the waste yarn can be taken out from the first compartment door 301 or the second compartment door 302. During material removal, the crushing shaft 202 can drive the arc scraper 205 to rotate through the support rod 203. The arc scraper 205 scrapes the waste yarn adhering to the inner wall of the collection box 101 to the first compartment door 301 or the second compartment door 302 for easy discharge. At the same time, the filter screen 106 set in the filter cover 102 can prevent short fibers from entering the filter cover 102 and affecting the normal use of the blower 105.
