Description

Technical Field

[0001] The present application relates to the technical field of looms, and in particular to an air jet loom for polyester fabrics. Background Art

[0002] Air-jet loom is a kind of textile machine. It has been used in industrial production since the 1970s. After years of improvement and production, it can achieve high-speed textile production. It has the advantages of low material consumption, high efficiency and low noise. Therefore, many fabrics such as pure cotton fabrics and polyester fabrics are produced by air-jet looms.

[0003] When the existing air-jet loom is in use, the yarn on the yarn frame is connected to the weft insertion mechanism, so that it slowly moves to the air-jet loom and is then woven. During the process, when the yarn is pulled, in order to ensure the tension of the yarn, it needs to be connected to the yarn clamp, and the tension of the yarn is adjusted by the tightness of the yarn clamping. The yarn clamp and the yarn are mostly in hard contact. During the movement of the yarn, it is easy to produce burrs due to friction with the yarn clamp, which will affect the subsequent weaving effect.

[0004] Therefore, the present invention proposes that the polyester fabric is improved by using an air jet loom. Summary of the invention

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Example

[0022] like Figure 1 - Fig.12 As shown, the air jet loom for polyester fabric proposed in the first embodiment of the present application includes a frame 1, on which a beating mechanism 101 is installed, and an air compressor 102 connected to the beating mechanism 101 is also installed on the frame 1. A take-up roller 103 is installed on one side of the frame 1. The air compressor 102 is used to blow air to the beating mechanism 101, and the yarn is blown into the gap of the fabric through the cooperation of the beating mechanism 101 to weave the fabric, and also includes: The bottom plate 2 has a frame 1 installed thereon, a mounting plate 201 is installed on the bottom plate 2, a fixing plate 202 is installed on the mounting plate 201, a load-bearing rod 2011 is installed on the fixing plate 202, a clamping plate 204 is also slidably installed on the mounting plate 201 through a connecting spring 203, the clamping plate 204 and the load-bearing rod 2011 are slidably matched, the clamping plate 204 and the fixing plate 202 are used to clamp the yarn, the connecting spring 203 is sleeved on the load-bearing rod 2011, and the load-bearing rod 2011 is used to limit the deformation direction of the connecting spring 203, when in use, a rotating piece is rotatably installed on the clamping plate 204, when it and the fixing plate 202 clamp the yarn, the friction between the clamping plate 204 and the yarn is reduced by the rotation of the rotating piece, which can clamp the yarn while reducing the possibility of friction on the peripheral side of the yarn causing the burrs; The clamping plate 204 elastically clamps the yarn by connecting the spring 203, further reducing the possibility of the device rigidly clamping the yarn, thereby reducing the possibility of the yarn fraying; The bearing roller 3 is rotatably mounted on the bottom plate 2. The bearing roller 3 is located on one side of the mounting plate 201 close to the take-up roller 103. The bearing roller 3 is driven by a motor or other driving member to rotate, thereby playing an auxiliary role in transporting the yarn. An inner cavity 301 is provided on the bearing roller 3, and a through hole 302 is provided on the bearing roller 3 for connecting the inner cavity 301 with the outside. A connecting pipe 303 rotatably connected to the bearing roller 3 is installed on the bottom plate 2. A water storage tank 304 is installed on the frame 1. The free end of the connecting pipe 303 is connected to the air compressor 102. The connecting pipe 303 is located in the water storage tank 304 and has a water permeable hole 305. A one-way valve is installed in the connecting pipe 303, so that the air compressor 102 can only blow air into the connecting pipe 303, and the water in the water storage tank 304 will not enter the air compressor 102, but will only exist in the connecting pipe 303. When in use, when the air compressor 102 drives the beating mechanism 101, air is also blown into the connecting pipe 303, and the water in the water storage tank 304 flows into the connecting pipe 303 through the water permeable hole 305 to wet the air. The water storage tank 304 is located at the bottom of the bottom plate 2. When the air moves upward, the water carried in the air gradually falls, so that the air remains moist while not being too moist. After the air enters the inner cavity 301, it is sprayed from the through hole 302 to contact the yarn, moistening the yarn but not making it wet, making the yarn surface smoother, thereby further reducing the possibility of the yarn having burrs when feeding, and improving the weaving effect of the device; Wherein, the device is used to weave polyester fabric; Compared with the prior art, a fixing plate 202 and a clamping plate 204 are installed on the bottom plate 2. When in use, the yarn is clamped by the two, and a carrying roller 3 is installed on the side of the mounting plate 201 close to the take-up roller 103. When in use, the air compressor 102 drives the beating mechanism 101 and also blows air into the inner cavity 301 through the connecting pipe 303. In the process, the air flow is wetted by the water storage tank 304, so that the yarn is wetted before it moves to the fixing plate 202, making the yarn surface smoother and reducing the possibility of fuzzing when clamped. Example

[0023] like Figure 5 As shown, the second embodiment further discloses the fixed plate 202 and the connecting tube 303 on the basis of the first embodiment. In the second embodiment, an oil chamber 205 is provided on the fixed plate 202, and vaseline is arranged in the oil chamber 205. A coating ball 2012 is rotatably installed on the fixed plate 202. When the coating ball 2012 rolls, it contacts with the vaseline or the yarn. An opening of the oil chamber 205 is provided on the fixed plate 202. A cover is threadedly connected to the fixed plate 202 for covering the oil chamber 205. When the device clamps the yarn, the yarn rubs against the coating ball 2012 and drives it to slide. When the coating ball 2012 rolls, the coating ball 2012 smears vaseline on the yarn, and the outside of the yarn is lubricated and wrapped by the vaseline, which further reduces the possibility of the yarn having fuzzy edges, thereby improving the subsequent weaving effect.

[0024] like Figure 3 , Figure 7 and Fig. 9 As shown in the second embodiment, a threaded rod 4 is rotatably installed on the mounting plate 201, and a sliding rod 5 is slidably installed on the mounting plate 201. One end of the connecting spring 203 is connected to the clamping plate 204, and the other end is installed with an extension plate 6, and the extension plate 6 is connected to the sliding rod 5. A hole is opened on the mounting plate 201, and the sliding rod 5 is slidably connected to the hole. The threaded rod 4 is threadedly connected to the extension plate 6. When the sliding rod 5 slides, the outer wall of the sliding rod 5 is blocked by the inner wall of the hole, so that the sliding of the sliding rod 5 can only slide on the mounting plate 201 along a straight line. When in use, the threaded rod 4 is rotated, and the extension plate 6 is restricted by the guidance of the sliding rod 5 with the rotation of the threaded rod 4, so that when the threaded rod 4 rotates, the extension plate 6 can be driven to move closer to or away from the mounting plate 201, so that the connecting spring 203 is in a compressed or stretched state, which can change the force of the clamping plate 204 when clamping the yarn. When the connecting spring 203 is in a normal state, the clamping plate 204 can also clamp the yarn; When the clamping force is not enough to keep the yarn in appropriate tension, the threaded rod 4 is rotated to cause the extension plate 6 to push the connecting spring 203 to compress it, thereby increasing the force applied to the clamping plate 204, thereby increasing the force of the device to clamp the yarn. When the force to clamp the yarn is too large, the threaded rod 4 is rotated to drive the extension plate 6 to pull the connecting spring 203, thereby reducing the force applied to the clamping plate 204, thereby reducing the force of the device to clamp the yarn, making it easier to adjust and control the clamping force of the device and increasing the practicability of the device.

[0025] like Figure 5 , Fig. 9 and Fig.12 As shown, in the second embodiment, a push plate 206 is slidably installed in the oil chamber 205, one end of the push plate 206 penetrates the inner wall of the oil chamber 205 and is located outside the fixed plate 202, and the movement path of the push plate 206 is close to or away from the smear ball 2012. When it approaches the smear ball 2012, the vaseline in the oil chamber 205 is pushed toward the smear ball 2012, so that the smear ball 2012 can be in contact with the vaseline more evenly, thereby increasing the smearing effect of the smear ball 2012; A return spring 209 is installed between the push plate 206 and the fixed plate 202, a driving wheel 207 is installed on the bottom plate 2, and the bearing roller 3 is connected to the driving wheel 207 through a pulley assembly. An inclined block 208 is installed at one end of the push plate 206 located outside the fixed plate 202, and a resistance block 2010 with the inclined block 208 is installed on the driving wheel 207. The resistance block 2010 is eccentrically installed on the driving wheel 207. When the driving wheel 207 rotates, the resistance block 2010 is driven to make a circular motion around its axis. The pulley assembly includes two pulleys and a belt, one of which is a pulley. One is connected to the driving wheel 207, and the other is connected to the bearing roller 3. The belt drives the two pulleys to be connected, so that when the bearing roller 3 rotates, the driving wheel 207 is also driven to rotate. When the driving wheel 207 rotates, the resistance block 2010 is gradually approached to the inclined block 208 and resists it, so that the pushing plate 206 slides in the direction close to the smearing ball 2012. When the driving wheel 207 continues to rotate, the resistance block 2010 is released from the resistance with the inclined block 208, and the pushing plate 206 is reset by the push of the reset spring 209, so as to facilitate the next push of the vaseline. When the vaseline in the oil chamber 205 is used up, the cover is opened and separated from the oil chamber 205 together with the push plate 206, new vaseline is added to the oil chamber 205, and the cover is put back.

[0026] like Figure 2 and Figure 4As shown, in embodiment 2, an extension tube 306 is installed on the connecting tube 303, and the extension tube 306 is connected to the connecting tube 303, and the tube mouth of the extension tube 306 is toward the load-bearing rod 2011. When the device is in use, the air in the connecting tube 303 is guided by the extension tube 306 so as to be blown toward the load-bearing rod 2011. When blowing, the yarn can better fit with the load-bearing rod 2011, so that the yarn is better clamped. In hot weather, when the yarn moves from the load-bearing roller 3 to the fixed plate 202, the moisture in the yarn is easily evaporated, and the yarn is humidified by the extension tube 306, which reduces the possibility of burring before being coated with vaseline, thereby increasing the practicality of the device.

[0027] like Figure 2 and Figure 6 As shown, in the second embodiment, a rolling wheel 7 is rotatably mounted on the bottom plate 2, and there are two rolling wheels 7. The gap between the rolling wheels 7 is used for the yarn to pass through. A driving rod 8 is mounted on the rolling wheel 7. The free end of the driving rod 8 is in contact with the pulley assembly, and the driving rod 8 is in contact with the inner frame wall of the belt of the pulley assembly. When in use, when the belt is transmitting, the driving rod 8 is driven to rotate by friction, and then the rolling wheels 7 are driven to rotate, so that the two rolling wheels 7 roll the yarn. The rolling wheels 7 are located between the load-bearing roller 3 and the fixed plate 202. When the yarn is transported, the possibility of the yarn burring is further reduced by rolling the yarn surface. Bristles may also be provided on the rolling wheel 7, and the bristles are arranged at an angle, tilted in the direction in which the yarn is transported, so that when the yarn is transported, the wetted yarn is brushed by the bristles, and the rough edges of the yarn surface from when the yarn roll is unwound are brushed, thereby increasing the practicality of the device. Example

[0028] like Figure 1 - Fig.12As shown, the third embodiment is further disclosed on the basis of the second embodiment. In the third embodiment, a vertical plate 9 is installed on the side of the mounting plate 201 away from the take-up roller 103, and a contact roller 10 is rotatably installed on the vertical plate 9. The contact roller 10 is used to contact the yarn. A circular plate 11 is installed on the contact roller 10, and a scraper plate 12 is slidably installed on the vertical plate 9. The scraper plate 12 is hinged with a hinged rod 13, and the free end of the hinged rod 13 is eccentrically hinged with the circular plate 11. When in use, after the yarn is coated with vaseline, it passes through the contact roller 10 and passes through the contact roller 11. 0 contact and resistance, part of the vaseline and the yarn are scraped off, the circular plate 11, the scraping plate 12 and the hinged rod 13 form a crank connecting rod structure, when in use, when the contact roller 10 rotates, the scraping plate 12 is driven to approach or move away from the contact roller 10, and the scraping plate 12 is located on the side of the vertical plate 9 away from the yarn. When in use, the contact roller 10 scrapes the vaseline on the yarn, and the scraping plate 12 scrapes the vaseline on the contact roller 10, reducing the content of vaseline on the contact roller 10, so that it can better scrape the vaseline on the yarn; When in use, the vaseline on the yarn is scraped off by the contact roller 10, which reduces the impact of the vaseline during subsequent weaving; When weaving is completed, the Vaseline can be washed off with laundry detergent or other means. Vaseline can also act as a lubricant during weaving.

[0029] In the third embodiment, a slide groove 14 is provided on the vertical plate 9, and the scraper plate 12 is slidably connected with the slide groove 14. A slope is provided on the side of the slide groove 14 close to the contact roller 10. A scraper plate 15 is installed on the vertical plate 9. When the scraper plate 12 slides in a direction away from the contact roller 10, the scraper plate 12 contacts the scraper plate 15. When the scraper plate 12 slides in the slide groove 14 toward the contact roller 10, it first slides parallel to the bottom of the groove, and then gradually slides in a direction away from the vertical plate 9 through the guidance of the slope. The scraper plate 12 moves until it contacts the contact roller 10. In the process of sliding on the inclined plane, the scraper plate 12 contacts the scraper plate 15 on the side facing the vertical plate 9, and then scrapes the vaseline on the contact roller 10. When the scraper plate 12 is away from the contact roller 10, it first releases the contact with the contact roller 10, and then contacts the scraper plate 15. At this time, the scraper plate 15 scrapes the vaseline on the scraper plate 12, which makes it easier for the scraper plate 12 to clean the contact roller 10 next time, thereby increasing the practicality of the device.

[0030] In embodiment three, a containing shell 308 is installed on the extension tube 306 through a bellows 307, and a plurality of nozzles 309 connected to the outside are provided on the containing shell 308. The height and orientation angle of the containing shell 308 can be adjusted through the bellows 307, and then the position of the nozzle 309 can be adjusted, so that the nozzle 309 can face the yarn, thereby improving the effect of wetting the yarn.

[0031] In the third embodiment, a plurality of friction grooves 16 are provided on the driving rod 8. The friction grooves 16 increase the friction between the driving rod 8 and the belt, so that the belt can better drive the driving rod 8 to rotate through friction, thereby increasing the practicality of the device.

[0032] When the device is in use, the yarn is wound on the take-up roller 103 and the yarn end is pulled onto the frame 1. During the process, the yarn passes through the load-bearing roller 3 and the fixed plate 202 and is ready for processing; During processing, when the yarn is pulled, it first passes through the load-bearing roller 3, is humidified by the airflow ejected from the inner cavity 301, is rolled by the rolling wheel 7, is held by the fixed plate 202 and the clamping plate 204 when passing between the two, and is coated with Vaseline by the rolling of the coating ball 2012. Finally, the excess Vaseline on the yarn is scraped off by the contact roller 10, thereby reducing the possibility of the yarn having burrs when being transported, thereby improving the practicability of the device.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
