Description

Technical Field

[0001] The utility model relates to the technical field of yarn sizing and shaping, in particular to a yarn sizing and shaping machine. Background Art

[0002] After the fiber is spun into yarn, it has low strength and more hairiness, which cannot meet the requirements of weaving. Sizing the yarn can improve the weavability of the warp yarn. After the yarn is sized, the sizing liquid forms a layer of sizing film on the surface of the yarn, which can not only fit the hairiness, but also make the yarn smooth and wear-resistant; in addition, part of the sizing liquid can also penetrate into the inner layer of the yarn, so that the fiber and the sizing liquid, and the fiber and the fiber are bonded to each other through the interface force, increasing the cohesion between the fibers and improving the breaking strength of the yarn; so in order to improve the strength of the yarn, reduce the hairiness, reduce the surface friction of the yarn and reduce friction, it is necessary to use a sizing machine to size the yarn.

[0003] The existing yarn sizing equipment requires that the yarn be pressed into the sizing liquid in the sizing tank by a sizing roller for sizing. Since the sizing liquid has a certain concentration and is relatively viscous, the sizing liquid sticking to the outside of the yarn will be relatively uneven, thus affecting the sizing quality of the yarn. When the yarn is shaped, the excess sizing liquid will solidify on the outer surface of the yarn, making it easy for the yarn to be interrupted during the weaving process due to the unevenness of the yarn, thereby greatly increasing the probability of thread breakage and affecting subsequent weaving.

DETAILED DESCRIPTION

[0029] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0030] Please refer to Figures 1 to 4 As shown, a yarn sizing and setting machine of the utility model comprises a working bin 4, a sizing mechanism, a scraping mechanism and a setting mechanism, wherein a yarn inlet is arranged at one end of the working bin 4, a yarn outlet is arranged at the other end of the working bin 4, the sizing mechanism is arranged at one side of the working bin 4 close to the yarn inlet, the scraping mechanism is arranged at one end of the sizing mechanism away from the yarn inlet, the setting mechanism is arranged at one side of the working bin 4 close to the yarn outlet, and the sizing mechanism, the scraping mechanism and the setting mechanism are all connected to the inner surface of the working bin 4;

[0031] The scraper mechanism includes a first bracket, a sleeve 11 and a scraper member 18. The outer surface of the sleeve 11 is connected to the outer surface of the working chamber 4 through the first bracket. A through hole is provided in the middle of the sleeve 11, and the scraper member 18 is provided inside the through hole. A scraper hole 20 is provided in the middle of the scraper member 18, and a plurality of first leakage holes 19 are provided at the lower part of the scraper member 18.

[0032] The working principle of the utility model is as follows: during actual production and use, when the yarn needs to be sized and shaped, the yarn can be introduced into the working chamber 4 through the yarn inlet, and then the yarn is sized through the sizing mechanism. After the sizing is completed, the yarn passes through the scraper hole 20, and the scraper hole 20 scrapes off the excess slurry on the yarn. Then the excess slurry on the scraper 18 leaks out from the first leakage hole 19, making the yarn surface smoother. Then the yarn is shaped by the shaping mechanism to make the slurry better adhere to the outer surface of the yarn. After the shaping is completed, the yarn is discharged through the yarn outlet.

[0033] Furthermore, the sizing mechanism includes a storage box 1, a feeding assembly, two groups of pushing assemblies 6 and an elastic absorber 16, and the pushing assemblies 6 are arranged on both sides of the elastic absorber 16, and the pushing assemblies 6 are connected to the working bin 4. The feeding assembly is arranged above the elastic absorber 16, and the feeding assembly is connected to the storage box 1, and the feeding assembly is connected to the working bin 4.

[0034] From the above description, it can be seen that when the yarn needs to be starched, the yarn passes through the center of the elastic absorber 16, and at the same time, the slurry in the storage box 1 drips onto the elastic absorber 16 through the feeding assembly, and then the elastic absorber 16 absorbs the slurry. When the yarn passes through the elastic absorber 16, the slurry absorbed in the elastic absorber 16 is coated on the yarn, so that there will not be too much slurry in the yarn.

[0035] Furthermore, the pushing assembly 6 includes a linear driving member 601, a sliding rod 602 and a moving member 603, one side of the moving member 603 is connected to the elastic absorption member 16, and the other side of the moving member 603 is slidably connected to the working chamber 4 through the sliding rod 602, and the linear driving member 601 is linearly driven and connected to the moving member 603.

[0036] From the above description, it can be seen that when it is necessary to make the elastic absorber 16 better contact with the yarn, the linear drive member 601 can be operated to make the linear drive member 601 drive the moving member 603 to push the elastic absorber 16, thereby causing the elastic absorber 16 to deform and make the elastic absorber 16 better fit with the yarn.

[0037] Furthermore, the feed assembly includes a feed pipe 10, a diverter pipe 17 and a discharge nozzle 15. An opening is provided at the bottom of the storage box 1. The upper part of the diverter pipe 17 is connected to the opening through the feed pipe 10. A plurality of discharge nozzles 15 are arranged at the lower part of the diverter pipe 17. The discharge nozzles 15 are all arranged above the elastic absorber 16. The diverter pipe 17 is connected to the inner surface of the working bin 4.

[0038] From the above description, it can be seen that when it is necessary to add slurry to the elastic absorber 16, the slurry in the storage box 1 can be introduced into the diversion pipe 17 through the feed pipe 10, and then the slurry is added to the elastic absorber 16 through the discharge nozzle 15.

[0039] Furthermore, it also includes a material receiving box 14 , and the material receiving box 14 is arranged below the elastic absorber 16 , and the material receiving box 14 is connected to the inside of the working chamber 4 .

[0040] From the above description, it can be seen that the material receiving box 14 is able to recover the slurry dripping from the elastic absorber 16 to reduce waste.

[0041] Furthermore, it also includes a reflux component, the lower part of the material receiving box 14 is provided with a first reflux port, the upper part of the material storage box 1 is provided with a second reflux port, and the first reflux port is connected to the second reflux port through the reflux component;

[0042] The reflux component includes a liquid extraction component 2 and a reflux pipe 5 , one end of the reflux pipe 5 is connected to the first reflux port, and the other end of the reflux pipe 5 is connected to the second reflux port through the liquid extraction component 2 .

[0043] From the above description, it can be seen that the reward for recycling the receiving box 14 can be achieved by running the pumping member 2 so that the pumping member 2 returns the slurry in the receiving box 14 to the storage box 1 through the reflux pipe 5, so that the slurry can be better recycled.

[0044] Furthermore, a plurality of second leakage holes 21 are provided at the lower portion of the sleeve 11 , and the second leakage holes 21 are all provided above the material receiving box 14 .

[0045] It can be seen from the above description that the slurry scraped off by the scraper 18 leaks into the sleeve 11 through the first leak hole 19 and then falls into the receiving box 14 through the second leak hole 21 for recovery.

[0046] Furthermore, the shaping mechanism includes a second bracket, a cylinder 13 and a plurality of drying lamps 12 . The cylinder 13 is connected to the inner surface of the working chamber 4 through the second bracket. The inner surface of the cylinder 13 is surrounded by a plurality of drying lamps 12 .

[0047] From the above description, it can be seen that after sizing is completed, the yarn passes through the center of the cylinder 13 and the drying lamp 12 is operated so that the drying lamp 12 irradiates the slurry coated on the yarn, so that the slurry is better attached to the yarn.

[0048] Furthermore, it also includes a retracting and releasing mechanism, the outer sides of the yarn inlet and the yarn outlet are both provided with a retracting and releasing mechanism, and the retracting and releasing mechanism is connected to the outer surface of the working chamber 4;

[0049] The retracting mechanism includes a third bracket 7, a rotating drive member 9 and a retracting shaft 8, one side of the third bracket 7 is rotatably connected to the outer surface of the working bin 4, the retracting shaft 8 is rotatably connected to the other side of the third bracket 7, and the rotating drive member 9 is drivingly connected to the retracting shaft 8.

[0050] From the above description, it can be seen that when the yarn needs to be reeled in, a rolled yarn can be placed on the reeling mechanism near the yarn inlet, and then the rotating driving member 9 is operated to make the rotating driving member 9 drive the reeling shaft 8 to rotate, so that the reeling shaft 8 unwinds the yarn, and one end of the yarn is wound around another reeling mechanism, so that the reeling mechanism rewinds the shaped yarn.

[0051] Furthermore, it also includes a PLC controller, which is electrically connected to the sizing mechanism and the shaping mechanism respectively.

[0052] From the above description, it can be seen that it is beneficial to adjust the parameters of the yarn sizing and setting machine through the PLC controller, and it is more convenient for operators to operate the yarn sizing and setting machine. Embodiment 1
