Description

Technical Field

[0001] The invention belongs to the technical field of production technology of down-proof down jackets, in particular to a sewing process of down-proof down jacket fabrics. Background Art

[0002] In the production process of down jackets, the upper layer and the lower layer of the down jacket need to be sewn together to form a down filling bag so that the down jacket forms an insulation layer;

[0003] After searching, a Chinese patent with publication number CN114808288A discloses a down jacket sewing device that prevents down from escaping. By setting a clamping device, the upper layer and the lower layer of the down jacket are clamped, so as to accurately locate the sewing route. At the same time, the clamping device moves in a directional manner in the sliding groove of the workbench to ensure the stability of the sewing route. The clamping device squeezes the upper layer and the lower layer to form a designed shape, thereby reducing the gap between the surface layers, increasing the tension at the sewing point, and reducing the vibration amplitude of the fabric caused by the insertion of the needle during the sewing process, which is beneficial to reducing fabric damage.

[0004] However, the above patent only provides a single wrinkle removal method for down jacket fabrics that prevent down from escaping, and the wrinkle removal effect is not ideal. Summary of the invention

[0005] The purpose of the present invention is to provide a sewing process for down jacket fabrics that are anti-down drilling, so as to solve the defects pointed out in the above background technology.

[0006] The technical solution of the present invention is as follows:

[0007] A sewing process for anti-drilling down jacket fabric comprises the following steps:

[0008] S1, passing the anti-drilling down jacket fabric between two pressing rollers at the front end of the sewing device, then passing around the bottom of the combing round cake, and finally passing through between two pressing rollers at the rear end;

[0009] S2, the anti-drilling down jacket fabric is pulled by an external traction unit, and the sewing machine sews the anti-drilling down jacket fabric. At the same time, the output shaft of the servo motor drives the active pulley (2022) to rotate, and the active pulley drives the driven pulley and the worm to rotate through the power belt. The rotation of the worm generates a spiral driving force, which drives the lever meshing with it to move along the axial direction of the worm. The lever drives the guide block to slide along the guide groove, so that under the connection between the multiple connecting steel cables and the multiple guide blocks, all the guide blocks slide along the guide groove at a uniform speed. During the rotation of the guide block along the guide groove, the U-shaped sleeve, the upper and lower pressure blocks and the two clamping plates are driven to move together through the sliding column. When the guide block moves from one end of the combing component to the direction of the sewing machine, the upper and lower pressure blocks move toward the middle and slide into between the upper and lower guide strips under the wedge force of the upper and lower oblique mouths. The two pressure blocks move toward the middle, driving the two clamping plates to approach each other. The first spring is stretched and stored, and the two clamping plates approach each other, so that the edge parts of the top and bottom of the anti-drilling down jacket fabric can be clamped;

[0010] S3, during the process of the two guide blocks moving from the combing component to the sewing machine, the two guide blocks move away from each other, and the U-shaped sleeve, the upper and lower pressing blocks and the two clamping plates are driven to move together through the sliding column and the second spring, so as to stretch the front and back of the anti-down drilling down jacket fabric. The second spring is subjected to the reverse force of the anti-down drilling down jacket fabric, so that the second spring is stretched to generate a rebound force. Under the action of the rebound force of the second spring, on the one hand, the two clamping plates stretch the front and back of the anti-down drilling down jacket fabric, and on the other hand, the elastic expansion and contraction of the second spring can prevent the anti-down drilling down jacket fabric from being torn;

At the same time, the output shaft of the servo motor 2021 drives the active pulley 2022 to rotate, and the active pulley 2022 drives the driven pulley 2020 and the worm 2019 to rotate through the power belt 2023. The rotation of the worm 2019 generates a spiral driving force, which pushes the lever 2017 engaged with it to move along the axial direction of the worm 2019, and the lever 2017 drives the guide block 205 to slide along the guide groove 204, so that under the connection between the multiple connecting steel cables 206 and the multiple guide blocks 205, all the guide blocks 205 are evenly moved along the guide groove 204. The guide block 205 slides at high speed, and the U-shaped sleeve 208, the upper and lower pressing blocks 2011 and the two clamping plates 2012 are driven to move together through the sliding column 207 during the rotation of the guide block 205 along the guide groove 204. When the guide block 205 moves from one end of the combing component 300 toward the direction of the sewing machine 500, the upper and lower pressing blocks 2011 move toward the middle and slide into between the upper and lower guide strips 2015 under the wedge force of the upper and lower bevels 2016. The two pressing blocks 2011 move toward the middle, driving the two clamping plates 2012 to approach each other, the first spring 2013 is stretched and stored, and the two clamping plates 2012 are moved toward each other, so that the edge parts of the top and bottom of the anti-drilling down jacket fabric can be clamped;

[0044] S3, during the movement of the two guide blocks 205 from the combing component 300 to the sewing machine 500, the two guide blocks 205 move away from each other, and the U-shaped sleeve 208, the upper and lower pressing blocks 2011 and the two clamping plates 2012 are driven to move together through the sliding column 207 and the second spring 2024, so as to stretch the front and back of the anti-down drilling down jacket fabric. The second spring 2024 is subjected to the reverse force of the anti-down drilling down jacket fabric, so that the second spring 2024 is stretched to generate a rebound force. Under the action of the rebound force of the second spring 2024, on the one hand, the two clamping plates 2012 can stretch the front and back of the anti-down drilling down jacket fabric, and on the other hand, the elastic expansion and contraction of the second spring can prevent the anti-down drilling down jacket fabric from being torn;

[0046] The sewing device comprises a sewing frame 100, and two wrinkle-removing components 200 symmetrically distributed on the top of the sewing frame 100 are provided. The wrinkle-removing components 200 comprise two fixed columns 201 fixedly installed on the top of the sewing frame 100, and two covering plates 202 distributed up and down are fixedly installed on the outer walls of the two fixed columns 201.

A plurality of guide blocks 205 distributed at equal distances are slidably installed inside the guide groove 204, and a connecting steel cable 206 is fixedly installed between two adjacent guide blocks 205. Two sliding columns 207 are fixedly installed on the outer side of the guide block 205, and the two sliding columns 207 are symmetrically distributed about the central axis of the guide block 205.

The inner walls of the two sliding holes 209 are respectively slidably connected to the outer walls of the two sliding columns 207. The top and bottom of the U-shaped sleeve 208 are penetrated by square notches 2010. The insides of the square notches 2010 are slidably installed with pressing blocks 2011. The ends of the two pressing blocks 2011 close to each other are fixedly installed with clamping plates 2012. Two first springs 2013 are fixedly installed between the side of the clamping plates 2012 away from the pressing blocks 2011 and the U-shaped sleeve 208. The sides of the upper and lower clamping plates 2012 close to each other are coated with a soft buffer particle coating.

[0048] Two fixed brackets 2014 distributed front and back are fixedly installed on the side of the upper and lower guide rails 203 close to the sewing machine 500, and a guide bar 2015 is fixedly installed between the two fixed brackets 2014. An oblique opening 2016 is provided at one end of the guide bar 2015 close to the combing component 300, and the position of the guide bar 2015 corresponds to the position of the pressing block 2011;

[0049] A lever 2017 is fixedly installed on the top of the guide block 205, wherein two adapter seats 2018 are fixedly installed on the top of a covering plate 202 located at the top of the guide rail 203, a worm 2019 is rotatably installed between the two adapter seats 2018, the worm 2019 is meshed with the lever 2017, and a driven pulley 2020 is fixedly installed on one end of the worm 2019, wherein a servo motor 2021 is fixedly installed on the top of the covering plate 202 on the same side as the adapter seat 2018, a driving pulley 2022 is fixedly installed on the output shaft of the servo motor 2021, and a power belt 2023 is commonly sleeved between the driving pulley 2022 and the driven pulley 2020, and a second spring 2024 is sleeved on the periphery of the sliding column 207, and the second spring 2024 is fixedly installed between the guide block 205 and the U-shaped sleeve 208;

[0050] Specifically, the output shaft of the servo motor 2021 drives the active pulley 2022 to rotate, and the active pulley 2022 drives the driven pulley 2020 and the worm 2019 to rotate through the power belt 2023. The rotation of the worm 2019 generates a spiral driving force, which pushes the lever 2017 engaged therewith to move along the axial direction of the worm 2019. The lever 2017 drives the guide block 205 to slide along the guide groove 204, so that all the guide blocks 205 slide along the guide groove 204 at a uniform speed under the connection between the multiple connecting steel cables 206 and the multiple guide blocks 205. During the rotation of the guide block 205 along the guide groove 204, the U-shaped sleeve 208, the upper and lower pressure blocks 2011 and the two clamping plates 2011 are driven by the sliding column 207. 012 moves together, when the guide block 205 moves from one end of the combing component 300 toward the sewing machine 500, the upper and lower pressing blocks 2011 move toward the middle and slide into between the upper and lower guide strips 2015 under the wedge force of the upper and lower bevels 2016, and the two pressing blocks 2011 move toward the middle, driving the two clamping plates 2012 to approach each other, the first spring 2013 is stretched and stored, and the two clamping plates 2012 are close to each other, so that the edge parts of the top and bottom of the anti-drilling down jacket fabric can be clamped. It should be noted that the end of the guide rail 203 close to the sewing machine 500 is smaller than the width of one end of the combing component 300. Therefore, in the process of moving from the combing component 300 to the sewing machine 500, the left The two right guide blocks 205 gradually move away from each other, and the two guide blocks 205 drive the U-shaped sleeve 208, the upper and lower pressing blocks 2011 and the two clamping plates 2012 to move together through the sliding column 207 and the second spring 2024, so as to stretch the front and back of the anti-drilling down jacket fabric, and eliminate the front and back wrinkles of the anti-drilling down jacket fabric. In this process, the second spring 2024 is subjected to the reverse force of the anti-drilling down jacket fabric, so that the second spring 2024 is stretched to generate a rebound force. Under the action of the rebound force of the second spring 2024, on the one hand, the two clamping plates 2012 can stretch the front and back of the anti-drilling down jacket fabric, and on the other hand, the elastic expansion and contraction of the second spring 2024 can prevent the anti-drilling down jacket fabric from being The pull rod 2017 that slides between the two guide bars 2015 slides out from the other end of the two guide bars 2015, and the resilience of the first spring 2013 is released, pushing the two clamping plates 2012 to reset, thereby releasing the upper and lower clamping of the anti-down drilling down jacket fabric. In addition, since the guide rail 203 increases linearly toward the end close to the sewing machine 500, the stretching force of the anti-down drilling down jacket fabric gradually increases linearly during the movement. Compared with the one-time pulling method, the linearly enhanced stretching method can avoid the rupture of the anti-down drilling down jacket fabric due to the sudden release of stress inside the anti-down drilling down jacket fabric, and can provide reasonable protection for the anti-down drilling down jacket fabric while removing wrinkles.

[0057] The anti-drilling down fabric is pulled by an external traction unit, and the sewing machine 500 sews the anti-drilling down fabric. At the same time, the output shaft of the servo motor 2021 drives the active pulley 2022 to rotate, and the active pulley 2022 drives the driven pulley 2020 and the worm 2019 to rotate through the power belt 2023. The rotation of the worm 2019 generates a spiral driving force, which pushes the lever 2017 engaged with it to move along the axial direction of the worm 2019, and the lever 2017 drives the guide block 205 to slide along the guide groove 204, so that under the connection between the multiple connecting steel cables 206 and the multiple guide blocks 205, all the guide blocks 205 slide along the guide groove 204 at a uniform speed. During the rotation of the guide block 205 along the guide groove 204, The slide column 207 drives the U-shaped sleeve 208, the upper and lower pressing blocks 2011 and the two clamping plates 2012 to move together. When the guide block 205 moves from one end of the combing component 300 toward the direction of the sewing machine 500, the upper and lower pressing blocks 2011 move toward the middle and slide into between the upper and lower guide strips 2015 under the wedge force of the upper and lower bevels 2016. The two pressing blocks 2011 move toward the middle, driving the two clamping plates 2012 to approach each other. The first spring 2013 is stretched and stored, and the two clamping plates 2012 are close to each other, which can clamp the edge parts of the top and bottom of the anti-drilling down jacket fabric. It should be noted that the end of the guide rail 203 close to the sewing machine 500 is smaller than the width of one end of the combing component 300. During the movement of the sewing component 300 toward the sewing machine 500, the left and right guide blocks 205 gradually move away from each other, and the two guide blocks 205 drive the U-shaped sleeve 208, the upper and lower pressing blocks 2011 and the two clamping plates 2012 to move together through the sliding column 207 and the second spring 2024, so as to stretch the front and back of the anti-drilling down jacket fabric, and eliminate the front and back wrinkles of the anti-drilling down jacket fabric. In this process, the second spring 2024 is subjected to the reverse force of the anti-drilling down jacket fabric, so that the second spring 2024 is stretched to generate a rebound force. Under the action of the rebound force of the second spring 2024, on the one hand, the two clamping plates 2012 can stretch the front and back of the anti-drilling down jacket fabric, and on the other hand, the elastic expansion and contraction of the second spring 2024 can avoid The anti-drilling down jacket fabric is not torn, and when the lever 217 that slides into between the two guide bars 2015 slides out from the other end of the two guide bars 2015, the resilience of the first spring 2013 is released, pushing the two clamping plates 2012 to reset, releasing the upper and lower clamping of the anti-drilling down jacket fabric, and because the guide rail 203 increases linearly toward the end close to the sewing machine 500, the stretching force of the anti-drilling down jacket fabric gradually increases linearly during the movement. Compared with the one-time pulling method, the linearly enhanced stretching method can avoid the anti-drilling down jacket fabric from being broken due to the sudden release of stress inside the anti-drilling down jacket fabric, and plays a reasonable protective role on the anti-drilling down jacket fabric while removing wrinkles;

[0058] At the same time, the combing shaft 302 is driven to rotate together with the combing disc 303 through the output shaft of the combing motor 307, and the combing disc 303 drives the multiple arc combing plates 305 and the multiple third springs 306 to rotate together through the multiple arc grooves 304. The multiple arc combing plates 305 rotate to continuously scrape the top of the anti-down drilling down jacket fabric in the opposite direction of the moving direction of the anti-down drilling down jacket fabric, thereby avoiding the accumulation of the anti-down drilling down jacket fabric on the surface of the sewing support plate 800, ensuring the flatness of the anti-down drilling down jacket fabric during sewing, and due to the sliding connection between the arc combing plate 305 and the arc groove 304 and the elastic force of the third spring 306, it can be ensured that the arc combing plate 305 is in full contact with the top of the anti-down drilling down jacket fabric, thereby performing sufficient scraping.

[0059] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
