Description

Technical Field

[0001] The present invention relates to the technical field of pulling equipment for elastic thermal seamless knitted underwear, in particular to a pulling device and a pulling method for elastic thermal seamless knitted underwear. Background Art

[0002] Seamless underwear production equipment is also called seamless underwear sewing equipment. The pulling device uses one or several groups of parallel yarns to feed all the working needles of the machine in the warp direction to form loops at the same time to form a knitted fabric. This method is called warp knitting, and the fabric is called warp knitted fabric. The machine that completes this warp knitting is called a warp knitting machine. The warp knitting machine is mainly composed of a weaving mechanism, a comb slewing mechanism, a warp feeding mechanism, a pulling and winding mechanism, and a transmission mechanism.

[0003] At present, the pulling and winding device includes a frame and a motor arranged on the frame, wherein a first pulling roller and a second pulling roller are arranged on the frame, the first pulling roller is linked to the motor, the second pulling roller is rotatably connected to the frame, and a cloth winding roller is provided below the second pulling roller, and the cloth winding roller is linked to the first pulling roller. Although this method can wind the woven fabric into a cloth roll, it is not easy for the pulling device under the existing technology to directly sense the tension of the knitted underwear cloth, which is not conducive to controlling the tension of the knitted underwear cloth. If the tension of the knitted underwear cloth is too large, it is easy to pull and deform the knitted underwear cloth. If the tension of the knitted underwear cloth is too small, the knitted underwear cloth will overlap, thereby causing wrinkles in the knitted underwear cloth. Summary of the Invention

[0012] Furthermore, a flattening mechanism is provided on the fixed rod, which includes a plurality of makeshift grooves opened on the outer wall of the pressure cylinder, and a plurality of flattening rods are fixedly connected to the side wall of the sliding ring. The flattening rods slide in the makeshift grooves, and an extrusion spring is sleeved on the side wall of the flattening rod.

[0016] S2: Tensioning and removing thread ends. The knitted fabric is pressed against the transmission and exhaust mechanism by the compression force of the compression spring, and the thread ends are removed through the small holes on the squeeze box.

[0017] S3: Knitted fabric is pushed flat, by utilizing the sliding ring in the tensioning dust removal mechanism to make the flattening arc plate push the knitted fabric back and forth;

[0018] S4: Tension adjustment, adjust the tension of the knitted fabric through the tension adjustment rod in the cloth collection mechanism.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention sets a tensioning dust removal mechanism. When the pressing column presses down the knitted underwear fabric, the knitted underwear fabric squeezes the extrusion box on the pressure cylinder downward, causing the extrusion box to slide. At this time, the extrusion box with fixed block 2 moves downward. The downward movement of fixed block 2 drives the driving rod to rotate. At this time, under the drive of the driving rod, fixed block 1 will slide along the fixed rod along with the sliding ring. At this time, the sliding of the sliding ring drives the dust removal telescopic rod to slide. The sliding of the dust removal telescopic rod drives the scraper to slide. The sliding of the scraper can scrape along the inner wall of the extrusion box to prevent thread ends and dust from clogging the small holes on the extrusion box, thereby affecting the thread end and dust removal effect of the device. By setting a reset spring, the sliding distance of the sliding ring can be controlled. At the same time, several sliding rings are subjected to the same elastic force, so that the force transmitted to the extrusion box by several driving rods is consistent, thereby ensuring that the knitted underwear fabric is subjected to uniform tension.

[0021] (2) The present invention sets a transmission and exhaust mechanism. At this time, the driving motor is started, and the output end of the driving motor drives the output shaft to rotate. The rotation of the output shaft drives the rotation of gear one. The rotation of gear one drives the rotation. The rotation of gear two drives the rotation column. The rotation of the rotation column drives the exhaust fan to rotate. When the exhaust fan rotates, suction is generated in the exhaust chamber. At the same time, the rotation of the output shaft drives the rotation of belt two. The rotation of belt two drives the rotation column. At this time, under the pressure of the compression column, the knitted underwear fabric is squeezed downward against the extrusion box on the pressure cylinder. In addition, the rotation of the exhaust fan causes the exhaust chamber to generate suction on the pressure cylinder cavity. At this time, the thread ends and dust on the knitted underwear enter the cavity of the pressure cylinder through the small holes on the extrusion box and are then discharged through the exhaust chamber. At this time, the knitted underwear fabric is pressed against the extrusion box on the pressure cylinder by the compression column, so that the knitted underwear fabric can always remain taut, thereby preventing the knitted underwear fabric from folding.

[0022] (3) The present invention provides a flattening mechanism. When the sliding ring slides on the fixed rod, the sliding ring drives the flattening rod to slide along the give way groove. At this time, the sliding of the flattening rod drives the flattening arc plate to slide. Under the action of the extrusion spring, the flattening arc plate is in close contact with the knitted underwear fabric. At this time, the sliding flattening arc plate can flatten the uneven fabric or the folded fabric, thereby preventing the knitted underwear fabric from folding and wrinkling, thereby improving the quality of the product.

[0023] (4) The present invention sets up a cloth collecting mechanism. When the knitted underwear fabric is being collected, the cloth collecting shaft provides pulling power. At this time, the output shaft rotates to drive the belt to rotate, and the belt rotates to drive the cloth collecting shaft to rotate. At this time, under the action of the tensioning adjustment rod, the knitted underwear fabric passes over the tensioning adjustment rod. Under the action of the tensioning telescopic rod, when the pulling force is small, the tensioning telescopic rod will extend upward, thereby increasing the tensioning force of the knitted underwear fabric and avoiding too small tensioning force, thereby protecting the knitted underwear fabric.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The purpose of this setting is to provide enough operating space when the knitted underwear cloth head is connected, making the device more convenient to use.

[0041] A transmission and exhaust mechanism 3 is provided directly above the equipment base 1. The transmission and exhaust mechanism 3 includes a gear 1 301 fixedly connected to the end of the output shaft 13 away from the drive motor 12. The side wall of the equipment base 1 is rotatably connected to a rotating column 302. The end of the rotating column 302 away from the inner wall of the equipment base 1 is fixedly connected to a gear 2 303. Gear 1 301 is engaged with gear 2 303. The function of this component is to set up the transmission and exhaust mechanism 3. At this time, the drive motor 12 is started, and the output end of the drive motor 12 drives the output shaft 13 to rotate. The rotation of the output shaft 13 drives gear 1 301 to rotate. The rotation of gear 1 301 drives gear 2 303 to rotate. The rotation of gear 2 303 drives the rotating column 302 to rotate.

[0042] The transmission exhaust mechanism 3 also includes an exhaust fan 305 fixedly connected to one end of the rotating column 302 close to the inner wall of the equipment base 1. The side wall of the equipment base 1 and the protective cover 304 form an exhaust chamber 306. The inner wall of the equipment base 1 is rotatably connected to a connecting shaft 307. The connecting shaft 307 is transmission-connected to the belt 215. The end of the connecting shaft 307 away from the inner wall of the equipment base 1 is fixedly connected to a pressure cylinder 308.

[0043] Example 2

[0044] The difference from Example 1 is that:

[0045] like Figures 1-9 As shown, the interior of the pressure cylinder 308 is provided with a tensioning dust removal mechanism 4, which includes a fixed rod 401 fixedly connected to the central axis of the pressure cylinder 308, a plurality of sliding rings 402 are slidably connected to the fixed rod 401, a fixed block 1 403 is fixedly connected to the side wall of the sliding ring 402, and the end of the fixed block 1 403 away from the sliding ring 402 is rotatably connected to the driving rod 404, and the inner wall of the extrusion box 309 is fixedly connected to a plurality of fixed blocks 2 405, and the fixed block 2 405 and the driving rod 404 is a rotating connection. The function of this component is to set a tensioning dust removal mechanism 4. When the pressing column 204 presses down the knitted underwear fabric, the knitted underwear fabric squeezes the extrusion box 309 on the pressure cylinder 308 downward, causing the extrusion box 309 to slide. At this time, the extrusion box 309 moves downward with the fixed block 2 405. The downward movement of the fixed block 2 405 drives the driving rod 404 to rotate. At this time, under the drive of the driving rod 404, the fixed block 1 403 follows the sliding ring 402 to slide along the fixed rod 401.

[0046] The tensioning dust-removing mechanism 4 also includes a dust-removing telescopic rod 406 fixedly connected to the side wall of the sliding ring 402.

A plurality of limiting rings 409 are fixedly connected to the fixed rod 401. The limiting ring 409 is fixedly connected to the return spring 408. The function of this component is that the sliding ring 402 drives the dust-removing telescopic rod 406 to slide, and the sliding of the dust-removing telescopic rod 406 drives the scraper strip 407 to slide. The scraper strip 407 can slide along the inner wall of the extrusion box 309 to prevent thread ends and dust from clogging the small holes on the extrusion box 309, thereby affecting the thread end and dust removal effect of the device. By setting the return spring 408, the sliding distance of the sliding ring 402 can be controlled. At the same time, the plurality of sliding rings 402 are subjected to the same elastic force, so that the force transmitted to the extrusion box 309 by the plurality of driving rods 404 is kept consistent, thereby ensuring that the knitted underwear fabric is subjected to uniform tension.

[0047] The fixed rod 401 is provided with a push-flat mechanism 5, which includes a plurality of paving grooves 501 provided on the outer wall of the pressure cylinder 308, and a plurality of push-flat rods 502 are fixedly connected to the side wall of the sliding ring 402. The push-flat rods 502 slide in the paving grooves 501, and a compression spring 503 is sleeved on the side wall of the push-flat rod 502. The end of the push-flat rod 502 away from the sliding ring 402 is fixedly connected to a push-flat arc plate 504. The function of this component is to set the push-flat mechanism 5. When the sliding ring 402 When the movable ring 402 slides on the fixed rod 401, the sliding ring 402 drives the flattening rod 502 to slide along the yield groove 501. At this time, the sliding of the flattening rod 502 drives the flattening arc plate 504 to slide. Under the action of the extrusion spring 503, the flattening arc plate 504 is in close contact with the knitted underwear fabric. At this time, the sliding flattening arc plate 504 can flatten the uneven fabric or the folded fabric, thereby preventing the knitted underwear fabric from folding and wrinkling, thereby improving the quality of the product.

The function of this component is By setting up the cloth collecting mechanism 6, when the knitted underwear fabric is in the process of being collected, the pulling power is provided by the cloth collecting shaft 605. At this time, the output shaft 13 rotates to drive the belt 14 to rotate, and the rotation of the belt 14 drives the cloth collecting shaft 605 to rotate. At this time, under the action of the tensioning adjustment rod 603, the knitted underwear fabric passes over the tensioning adjustment rod 603. Under the action of the tensioning telescopic rod 604, when the pulling force is small, the tensioning telescopic rod 604 will extend upward, thereby increasing the tensioning force of the knitted underwear fabric, avoiding excessively small tensioning force, and protecting the knitted underwear fabric.

[0049] A pulling device and a pulling method for elastic warm seamless knitted underwear include the following steps:

[0050] S1: Connecting the knitted cloth head: Lifting the adjustment handle 205 will drive the pressing column 204 on the slide bar 202 to lift upwards, making it easier to connect the knitted cloth head to the inside of the device;

[0052] S3: The knitted fabric is flattened by driving the sliding ring 402 in the tensioning dust removal mechanism 4 so that the flattening arc plate 504 pushes the knitted fabric back and forth;

[0053] S4: Tension adjustment: adjust the tension of the knitted fabric through the tension adjustment rod 603 in the fabric collecting mechanism 6.

[0054] A specific application of this embodiment is:

[0055] When the knitted underwear cloth is connected, the adjusting handle 205 is lowered, and the pressing column 204 pushes the cloth downward to squeeze the cloth, so that the knitted underwear cloth can be connected. The purpose of this setting is to provide enough operating space when the knitted underwear cloth head is connected, making the device more convenient to use; then, by setting the transmission exhaust mechanism 3, the drive motor 12 is started, and the output end of the drive motor 12 drives the output shaft 13 to rotate, and the output shaft 13 rotates The rotation of gear 301 drives gear 2 303 to rotate, and the rotation of gear 2 303 drives the rotating column 302 to rotate. The rotation of rotating column 302 drives the exhaust fan 305 to rotate. When the exhaust fan 305 rotates, suction is generated in the exhaust chamber 306. At the same time, the output shaft 13 rotates to drive the belt 2 15 to rotate. The rotation of belt 2 15 drives the rotating column 302 to rotate. At this time, under the pressure of the pressing column 204, the knitted underwear fabric is pressed downwardly against the extrusion box 309 on the pressure cylinder 308. In addition, the rotation of the exhaust fan 305 causes the exhaust chamber 306 to generate suction on the pressure cylinder 308. At this time, the thread ends and dust on the knitted underwear enter the cavity of the pressure cylinder 308 through the small holes on the extrusion box 309 and are then discharged through the exhaust chamber 306. At this time, the knitted underwear fabric is pressed by the pressing column 204 against the extrusion box 309 on the pressure cylinder 308, so that the knitted underwear fabric can always be kept taut, thereby preventing the knitted underwear fabric from folding.

[0056] By setting the tensioning dust removal mechanism 4, when the pressing column 204 presses down the knitted underwear fabric, the knitted underwear fabric presses the squeezing box 309 on the pressure cylinder 308 downward, causing the squeezing box 309 to slide. At this time, the squeezing box 309 moves downward with the fixed block 2 405, and the fixed block 2 405 moves downward to drive the driving rod 404 to rotate. At this time, the fixed block 1 403 follows the sliding ring 402 to slide along the fixed rod 401 under the drive of the driving rod 404. At this time, the sliding ring 402 slides and drives the dust removal telescopic rod 406 to slide, and the dust removal The sliding of the telescopic rod 406 drives the scraper 407 to slide, and the sliding of the scraper 407 can scrape along the inner wall of the squeezing box 309 to prevent thread ends and dust from clogging the small holes on the squeezing box 309, thereby affecting the thread end and dust removal effect of the device. By setting a reset spring 408, the sliding distance of the sliding ring 402 can be controlled, and at the same time, the multiple sliding rings 402 are subjected to the same elastic force, so that the forces transmitted to the squeezing box 309 by the multiple driving rods 404 are consistent, thereby ensuring that the knitted underwear fabric is subjected to uniform tension. The flattening mechanism 5 is provided. When the sliding ring 402 slides on the fixed rod 401, the sliding ring 402 drives the flattening rod 502 to slide along the yielding groove 501. At this time, the flattening rod 502 slides and drives the flattening arc plate 504 to slide. Under the action of the extrusion spring 503, the flattening arc plate 504 is in close contact with the knitted underwear fabric. At this time, the sliding flattening arc plate 504 can flatten the uneven fabric or the folded fabric, thereby preventing the knitted underwear fabric from folding and wrinkling, thereby improving the quality of the product. By setting the cloth collecting mechanism 6 When the knitted underwear fabric is being collected, the pulling force is provided by the cloth collecting shaft 605. At this time, the output shaft 13 rotates to drive the belt 14 to rotate, and the rotation of the belt 14 drives the cloth collecting shaft 605 to rotate. At this time, under the action of the tensioning adjustment rod 603, the knitted underwear fabric passes over the tensioning adjustment rod 603. Under the action of the tensioning telescopic rod 604, when the pulling force is small, the tensioning telescopic rod 604 will extend upward, thereby increasing the tensioning force of the knitted underwear fabric and avoiding the protection of the knitted underwear fabric due to too little tension.
