Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of textile equipment, and particularly to a textile equipment with a self-cleaning function. Background Technique
[0002] A loom is a core device in the textile industry, which is used to interweave warp yarns (longitudinal yarns) and weft yarns (transverse yarns) according to specific rules to form fabrics (such as cotton cloth, silk, denim, etc.).
[0003] When the loom is running, during the high-speed friction and stretching process of the warp and weft yarns, the fiber surface will shed due to mechanical action, forming short fibers or fluff. The fluff adheres to the fabric surface, which will not only affect the appearance and feel, but even cause defects in the product. In the prior art, to solve this problem, a cleaning roller with a brush is usually provided at one end of the outlet of the loom. Through the rotation of the cleaning roller on the fabric surface, the brush can clean the fluff on the fabric surface, and the cleaned fluff will wind around the outside of the brush. However, after long-term use, a large amount of fluff will wind around the outside of the cleaning roller. If it is not cleaned, the cleaning effect of the cleaning roller on the fluff on the fabric surface in the subsequent process will be greatly reduced. And using the manual method to clean the fluff not only requires the loom to stop, but also takes a long time to clean, which not only increases the workload of workers, but also reduces the production efficiency of the fabric. Summary of the Invention
[0004] The purpose of the present invention is to provide a textile equipment with a self-cleaning function to solve the problems raised in the above background technique.

A plurality of combing rods are respectively arranged inside their corresponding semi-circular grooves. T-shaped sliders one are fixedly installed on both sides of the first long plate and the second long plate. T-shaped chutes one are formed at both ends inside each mounting block. A plurality of T-shaped sliders one are respectively slidably installed inside their corresponding T-shaped chutes one.
[0011] Preferably, the scraping mechanism includes two discs and a plurality of guide rods. The two discs are respectively fixedly installed on one side of the two brackets close to each other. The plurality of guide rods are respectively fixedly connected to their corresponding mounting blocks. Guide grooves are formed inside the two discs. The plurality of guide rods are respectively slidably installed inside their corresponding guide grooves.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] By introducing the fabric in the loom body to the bottom of the cleaning roller, after cleaning the fluff on the surface of the fabric by the cleaning roller, the first driving mechanism drives the rotating rod and the combing rod to rotate, and picks out the fluff attached to the brush of the cleaning roller, so as to achieve the effect of automatically cleaning the fluff wound in the cleaning roller, without manual cleaning, and solves the problem that in the prior art, due to a large amount of fluff wound outside during long-term use, the cleaning effect of the cleaning roller on the fluff on the fabric surface in the subsequent process is greatly reduced.
[0016] Through the provided scraping mechanism, when the scraper rotates to a certain angle, the first scraper can scrape the fluff outside the combing rod into the fluff collection box for collection, so as to ensure the effect of the combing rod picking out the fluff wound in the cleaning roller. And under the action of the separation mechanism, when the scraper moves to a certain position, the first long plate and the second long plate are separated. Such a setting prevents the remaining fluff on the outside of the combing rod from being pushed between the rotating rods when the first long plate and the second long plate return to their positions, and avoids the accumulation of the remaining fluff between the scraper and the rotating rods.

Push blocks 35 are fixedly installed at the bottoms of the inner walls on both sides of the frame 16. The two push blocks 35 cooperate with the two T-shaped sliders I 21 respectively.
[0039] Working principle: When in use, start the first motor 8. The first motor 8 drives the cleaning roller 3 to rotate, thereby driving the transmission gear 9 outside the cleaning roller 3 to rotate. Since the two transmission gears 9 are meshed with each other, the other transmission gear 9 drives the spline sleeve 7 to rotate. The spline shaft 6 that cooperates with the spline sleeve 7 drives the rotating rod 4 to rotate. The cleaning roller 3 and the rotating rod 4 rotate synchronously. The cleaning roller 3 sweeps the fluff on the surface of the fabric conveyed by the loom body 1. After the cleaning, the fluff is wound around the brush in the cleaning roller 3. As the rotating rod 4 rotates, the rotating rod 4 drives multiple combing rods 5 to rotate. The multiple combing rods 5 pick out the fluff attached to the brush of the cleaning roller 3, so as to achieve the effect of automatically cleaning the fluff wound in the cleaning roller 3, without manual cleaning, and solve the problem that in the prior art, after the cleaning roller 3 is used for a long time, due to a large amount of fluff wound outside, the cleaning effect of the cleaning roller 3 on the fluff on the fabric surface in the subsequent process is greatly reduced.
[0040] By starting the motor 2 10, the motor 2 10 drives the transmission rod 11 connected thereto to rotate, and the transmission rod 2 12 moves accordingly, and pulls the rotating rod 4 to move back and forth, thereby driving the multiple combing rods 5 to move back and forth, thereby improving the effect of the multiple combing rods 5 picking out the entangled hair in the cleaning roller 3.
[0041] As the rotating rod 4 rotates, the two fixing rings 15 and the multiple frames 16 outside thereof rotate synchronously, and the multiple mounting blocks 17 rotate synchronously. The multiple mounting blocks 17 drive the corresponding guide rods 24 to rotate, and the multiple guide rods 24 slide in the corresponding guide grooves. When one of the guide rods 24 slides from the arc groove 25 to the inside of the adjustment groove 26, the guide rod 24 drives the corresponding mounting block 17 to slide under the action of the specific shape of the adjustment groove 26, and the mounting block 17 drives the T-shaped sliders 27 on both sides thereof to move away from the inside of the corresponding T-shaped slide grooves 28. One side of the rotating rod 4 slides, and the movement process of the separation mechanism in the mounting block 17 is as follows: as the mounting block 17 slides, the mounting block 17 drives the long plate 18 and the long plate 2 19 to slide synchronously, so that the fluff outside the plurality of combing rods 5 can be pushed out of the combing rod 5, and the fluff falls into the fluff collection box 14 in the fluff collection frame 13. The mounting block 17 gradually approaches the two push rods 34. When the two push rods 34 are inserted into the two slots 33 and act on the two plug-in blocks 32, the two plug-in blocks 32 are forced to separate from the inside of the slots 33 and squeeze the corresponding spring 2 31. Under the action of two springs 1 29, the two T-shaped sliders 1 21 drive the corresponding long plates 1 18 and long plates 2 19 to move away from each other, so that the multiple semicircular grooves 20 are away from the combing rod 5. As the rotating rod 4 continues to rotate, the mounting block 17 continues to slide along the adjusting groove 26. At this time, the mounting block 17 drives the long plates 1 18 and long plates 2 19 to move to the side close to the rotating rod 4. During this process, the long plates 1 18 and long plates 2 19 are separated, preventing the long plates 1 18 and long plates 2 19 from pushing the residual hair outside the multiple combing rods 5 between the rotating rods 4 when they return to their original positions, thereby avoiding To prevent residual lint from accumulating between the scraper and the rotating rod 4, when the mounting block 17 moves to the end closest to the rotating rod 4, the two push blocks 35 act on their respective corresponding T-shaped sliders 21, and the two T-shaped sliders 21 are forced to move closer to each other. When the two plug blocks 32 correspond to the two slots 33 respectively, the two plug blocks 32 extend into the interior of the two slots 33 under the action of their respective corresponding springs 2 31. At this time, the long plate 18 and the long plate 2 19 are re-docked, and in subsequent work, the lint on the outside of the multiple combing rods 5 will be pushed into the interior of the lint collection box 14.
