Description

Technical Field

[0001] This utility model relates to the field of knitted fabric tensioning technology, and in particular to a variable frequency sportswear knitted fabric tensioning device. Background Technology

[0002] Knitted fabric for sportswear is a type of knitted fabric. Knitted fabric is a fabric formed by bending yarns into loops and interlocking them using knitting needles. The difference between knitted and woven fabrics lies in the different forms of the yarns within the fabric. Knitting is divided into weft knitting and warp knitting. Knitted fabrics are widely used in clothing fabrics and linings, home textiles, and other products, and are loved by consumers. During the production process of knitted fabrics, the fabric needs to be stretched. Stretching the fabric allows for even stress distribution. Before being stretched, the knitted fabric fibers are tightly packed. After stretching, the knitted fabric has good moisture absorption and breathability, making it soft, comfortable to wear, and warm.

[0003] However, in related technologies, after the knitted fabric is produced, its surface will be contaminated with dust, lint, and other impurities during processing, which can easily affect the subsequent stretching of the sportswear knitted fabric, reduce the quality of the sportswear knitted fabric, and make it inconvenient to adjust the frequency of stretching according to different specifications of sportswear knitted fabric, thus reducing the stretching effect of the sportswear knitted fabric. Therefore, we propose a variable frequency sportswear knitted fabric stretching device to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A variable frequency sportswear knitted fabric pulling device includes a frame 1, with two traction rollers 24 rotatably connected to the inner walls of the front and rear sides of the frame 1. A variable frequency pulling mechanism 2 for pulling the sportswear knitted fabric is provided between the frame 1 and the two traction rollers 24.

The dust removal mechanism 7 includes a brushing component 8 disposed in the dust collection box 4 and a dust collection component 9 disposed between the dust collection box 4 and the dust collection box 90.

[0024] Furthermore, refer to Figure 1 and Figure 2 As shown, the variable frequency traction mechanism 2 includes a traction motor 22 fixedly connected to the front side of the frame 1 and two rotating shafts 21 rotatably connected to the inner walls of the front and rear sides of the frame 1. Two traction rollers 24 are respectively fixedly sleeved on the outer side of the corresponding rotating shafts 21. A frequency converter 23 is fixedly connected to the top of the traction motor 22. Gears 25 are fixedly connected to the rear ends of the two rotating shafts 21. The two gears 25 mesh with each other. A controller 6 is fixedly connected to the front side of the frame 1. The traction motor 22 and the frequency converter 23 are electrically connected to the controller 6.

[0025] The above scheme is adopted: the sportswear knitted fabric is passed through the opening 5 and wound between two guide rollers 10, four guide rollers 3 and two traction rollers 24. Through the settings of the controller 6 and the frequency converter 23, the output power of the traction motor 22 can be adjusted, thereby adjusting the rotation speed of the traction rollers 24, and thus adjusting the pulling speed of the sportswear knitted fabric to achieve the effect of frequency conversion pulling. The traction motor 22 drives the rotation of a rotating shaft 21. Under the transmission meshing of two gears 25, the two rotating shafts 21 rotate in opposite directions. The two rotating shafts 21 drive the two traction rollers 24 to rotate in opposite directions, thereby achieving the effect of pulling the sportswear knitted fabric.

[0026] Furthermore, openings 5 ​​are provided on both sides of the dust collection box 4, and two guide rollers 10 are rotatably connected to the inner walls of the front and rear sides of the dust collection box 4 for guiding the knitted fabric of sportswear, so as to facilitate the entry of the knitted fabric of sportswear into the dust collection box 4 and guide the knitted fabric of sportswear at the same time.

[0027] Furthermore, refer to Figure 3 and Figure 4 As shown, the brushing component 8 includes four support plates 81, all of which are fixedly connected to the inner walls of the front and rear sides of the dust collection box 4. A drive motor 82 is fixedly connected to one side of each of the two support plates 81 on the left side.

Several cleaning brushes 86 for cleaning the surface of sportswear knitted fabric are fixedly connected to the outside of the conveyor belt 84. Several connecting plates 85 are fixedly connected to the outside of the conveyor belt 84, and the cleaning brushes 86 are fixedly connected to the outside of the connecting plates 85.

[0028] The above solution is adopted: two drive motors 82 drive two rotating rollers 83 and a conveyor belt 84 to run. The conveyor belt 84 drives multiple connecting plates 85 and cleaning brushes 86 to run. With the setting of two sets of cleaning brushes 86, dust, threads, lint and other debris attached to the upper and lower surfaces of the sportswear knitted fabric can be scraped off, thereby improving the dust removal effect.

[0029] Furthermore, refer to Figure 1 and Figure 3As shown, the vacuuming assembly 9 includes a vacuum pump 91 fixedly connected to the inner wall of the bottom of the vacuum box 90, a collection box 95 slidably fitted inside the vacuum box 90, and a vacuum pipe 97 fixedly connected to the top of the vacuum box 90. The top of the vacuum pipe 97 is fixedly connected to a suction cup 98, and the top of the suction cup 98 is fixedly connected to multiple suction nozzles 99. Both the suction nozzles 99 and the suction cup 98 are located inside the dust collection box 4. An air outlet pipe 92 is fixedly connected to one side of the vacuum pump 91, and one end of the air outlet pipe 92 passes through one side of the vacuum box 90. A filter screen 96 is fixedly connected to the bottom of the collection box 95. Two magnets 94 are fixedly connected to the sides of the collection box 95 and the vacuum box 90 that are close to each other. The two magnets 94 located on the same horizontal plane attract each other. An installation port 93 is opened on one side of the vacuum box 90, and the collection box 95 is slidably fitted inside the installation port 93.

[0030] Using the above method: After the debris is scraped off, the suction of the vacuum pump 91 can suck the scraped dust, lint, and other debris into the nozzle 99, suction cup 98, and vacuum tube 97, and finally into the vacuum box 90. After being filtered and intercepted by the filter screen 96, the debris is collected in the collection box 95, while the air is discharged from the air outlet pipe 92. When it is necessary to clean the debris collected in the collection box 95, pull the collection box 95 outward to separate the magnet 94 on the collection box 95 from the magnet 94 on the vacuum box 90, so that the collection box 95 can be pulled out for cleaning. After cleaning, push the collection box 95 into the vacuum box 90, where it can be attracted and fixed by the magnet 94.

[0031] In this invention, the knitted sportswear fabric is passed through the opening 5 and wound between two guide rollers 10, four guide rollers 3, and two traction rollers 24. By setting the controller 6 and the frequency converter 23, the power output of the traction motor 22 can be adjusted, thereby adjusting the rotation speed of the traction rollers 24, and thus adjusting the pulling speed of the knitted sportswear fabric, achieving the effect of frequency conversion pulling. The traction motor 22 drives the rotation of a rotating shaft 21. Under the transmission meshing of two gears 25, the two rotating shafts 21 rotate in opposite directions, and the two rotating shafts 21 drive the two traction rollers 24 to rotate in opposite directions, thereby achieving the effect of pulling the knitted sportswear fabric.

[0032] Two drive motors 82 drive two rotating rollers 83 and a conveyor belt 84. The conveyor belt 84 drives multiple connecting plates 85 and cleaning brushes 86. The two sets of cleaning brushes 86 scrape off dust, threads, lint, and other debris adhering to the upper and lower surfaces of the sportswear knitted fabric. After scraping, the suction power of the vacuum pump 91 draws the scraped dust, threads, lint, and other debris into the nozzle 99, suction cup 98, and suction pipe 97, ultimately into the vacuum box 90, where it passes through a filter. The filter 96 intercepts debris, which is then collected in the collection box 95. Air is discharged from the vacuum chamber 90 through the exhaust pipe 92. When it is necessary to clean the debris collected in the collection box 95, pull the collection box 95 outward to separate the magnet 94 on the collection box 95 from the magnet 94 on the vacuum chamber 90, and the collection box 95 can be pulled out for cleaning. After cleaning, push the collection box 95 back into the vacuum chamber 90, where it will be attracted and fixed by the magnet 94.
