Description

Technical Field

[0001] This application relates to the field of textile machinery technology, and in particular to an automatic sewing device and sewing method for mesh sleeves. Background Technology

[0002] In the textile industry, the order volume for knitted products has been increasing in recent years. In the sewing process of knitted sweaters, the traditional method for the mesh sleeve process is to operate entirely manually, which has a low degree of automation, a large workload, a heavy burden on workers, and low production efficiency. At the same time, because the mesh sleeve process is difficult to operate, a lot of time needs to be spent training operators in the early stage, resulting in high labor training and time costs. Moreover, the skill level of operators varies from person to person, so manual operation often leads to inconsistent quality of sewn products. Summary of the Invention

[0003] Therefore, it is necessary to provide an automatic sewing device and sewing method for mesh sleeves that automates the sewing process, has high production efficiency, and high quality stability.

[0004] The first aspect of this application provides an automatic sewing device for mesh sleeves, which includes a machine base and an edge control mechanism, a feeding mechanism, a rotating mechanism, a correction mechanism, a code adjustment mechanism, and a sewing mechanism disposed on the machine base.

[0005] The edge control mechanism includes a pressing roller and a pressing drive. The pressing drive is used to drive the pressing roller to move; the pressing roller is used to cooperate with the feeding mechanism to drive the cut piece to move.

[0006] The rotating mechanism is connected to the feeding mechanism and is used to drive the feeding mechanism to rotate so that the cut piece rotates by a predetermined angle.

[0007] The correction mechanism is used to drive the cut piece to move in the opposite direction of the offset direction;

[0008] The adjusting mechanism is connected to the feeding mechanism and is used to control the tension of the cut pieces.

[0009] The sewing mechanism is used to sew cut pieces.

[0010] In some embodiments, the feeding mechanism includes a feeding roller, an auxiliary roller, a feeding drive, and an auxiliary drive. The feeding roller and the auxiliary roller are used for feeding the cut pieces by fitting them together. The feeding drive is connected to the feeding roller and is used to drive the feeding roller to rotate. The auxiliary drive is connected to the auxiliary roller and is used to drive the auxiliary roller to rotate.

[0011] In some embodiments, the edge control mechanism further includes a first lead screw module connected to the feeding roller and used to drive the feeding roller to move in the front-back direction.

[0012] In some embodiments, the coding mechanism further includes a second lead screw module connected to an auxiliary rolling element for driving the auxiliary rolling element to move in the left-right direction.

[0013] In some embodiments, the correction mechanism includes a correction link and a correction mechanism drive member. The correction mechanism drive member is connected to the correction link and is used to drive the correction link to rotate so as to move the cut piece in the opposite direction of the offset direction.

[0014] In some embodiments, the automatic sewing device for mesh sleeves further includes a stop fixing mechanism, which includes a stop fixing arm and a stop fixing drive. The first end of the stop fixing arm is connected to the stop fixing drive, and the second end of the stop fixing arm is bent so that the bent portion extends toward the first end. The length of the bent portion is equal to the width of the stop of the fabric piece.

[0015] In some embodiments, the automatic sewing device for mesh sleeves also includes a control mechanism electrically connected to the edge control mechanism, the feeding mechanism, the rotating mechanism, the correction mechanism, the code adjustment mechanism, and the sewing mechanism.

[0016] In some embodiments, the automatic sewing device for mesh sleeves also includes a positioning mechanism located on the machine platform for positioning the edges of the cut pieces.

[0017] In some embodiments, the adjacent mechanism includes a sensor electrically connected to a control mechanism, which controls the movement of the adjacent mechanism based on the position signal from the sensor.

[0018] A second aspect of this application provides a sewing method, which includes the following steps:

[0019] Place the cut piece on the feeding mechanism, control the pressing drive to drive the pressing roller to move onto the feeding mechanism, control the feeding mechanism to move to drive the pressing roller to rotate, and the feeding mechanism and the pressing roller cooperate to drive the cut piece to move.

[0020] During the sewing process, the control of the correction drive component drives the correction linkage to rotate, thereby driving the cut piece to move in the opposite direction of the offset direction;

[0021] Control the sewing mechanism to sew the cut pieces;

[0022] When the positional relationship between the cut piece and the sewing mechanism needs to be adjusted, the rotating mechanism is controlled to rotate, which in turn drives the feeding mechanism to rotate, causing the cut piece to rotate by a predetermined angle.

[0023] When the tension of the cut piece needs to be adjusted, the control mechanism drives the auxiliary rolling element to move in the left and right directions.

[0024] The aforementioned automatic sewing device for mesh sleeves achieves automation, high production efficiency, and high quality stability in the sewing process through the rational distribution of multiple mechanisms such as multi-edge control mechanism, feeding mechanism, rotation mechanism, and correction mechanism, and the efficient cooperation and coordination among these mechanisms.

[0050] The direction parallel to the long axis of the feeding roller is defined as the front-back direction, and the direction parallel to the short axis of the feeding roller is defined as the left-right direction.

[0051] See Figure 1-8 As shown, one embodiment of this application provides an automatic sewing device for mesh sleeves. The device includes a machine base, an edge control mechanism 10, a feeding mechanism 20, a rotating mechanism 30, a correction mechanism 40, a code adjustment mechanism 50, a sewing mechanism 60, and a control mechanism.

[0052] See Figure 1 and 2 As shown, the edge control mechanism 10 is mounted on the machine base and includes a pressing roller 110 and a pressing drive 120. The pressing roller 110 is used to assist the cutting piece to be sewn to move forward. The pressing roller 110 is rotatably connected to the pressing drive 120. The pressing drive 120 is used to drive the pressing roller 110 to rotate. The pressing roller 110 cooperates with the feeding mechanism 20 to feed materials and drive the cutting piece to move.

[0053] In some embodiments, the edge control mechanism 10 further includes a first lead screw module 130, which is connected to the feeding roller 210 and is used to drive the feeding roller 210 to move in the front-back direction, thereby adjusting the position of the cut piece to be processed. Specifically, when the first lead screw module 130 moves back and forth, it drives the feeding roller 210 to move back and forth, thereby causing the cut piece fitted on the feeding roller 210 to move back and forth, ensuring that the cut piece always moves within a preset position range. The control mechanism is electrically connected to the pressing drive 120.

[0054] See Figure 1 and 3As shown, the feeding mechanism 20 is mounted on the rotating mechanism 30 and includes a feeding roller 210, an auxiliary roller 230, a feeding drive 220, and an auxiliary drive 240. The feeding roller 210 and the auxiliary roller 230 are used to fit and feed the cut pieces to be processed. The feeding drive 220 is connected to the feeding roller 210 and drives the feeding roller 210 to rotate. The auxiliary drive 240 is connected to the auxiliary roller 230 and drives the auxiliary roller 230 to rotate. The control mechanism is electrically connected to the feeding drive 220 and the auxiliary drive 240.

[0055] See Figure 1 and 4 As shown, the rotating mechanism 30 is movably mounted on the machine base and includes a first support plate 310, a second support plate 320, and a rotating mechanism drive 330. The first support plate 310 supports the mechanism 30 to be rotated; the mechanism 30 includes an edge control mechanism 10, a feeding mechanism 20, a correction mechanism 40, and a coding mechanism 50. The second support plate 320 is movably connected to the first support plate 310, and both ends of the second support plate 320 are provided with support members to support the first support plate 310. The rotating mechanism drive 330 is sequentially connected to the second support plate 320 and the first support plate 310, providing rotational power to the first support plate 310, driving the mechanism 30 mounted on the first support plate 310 to rotate, thereby rotating the cut piece sleeved on the feeding roller 210 and the auxiliary roller 230 to a suitable processing position. The control mechanism is electrically connected to the rotating mechanism drive 330.

[0056] Specifically, for example, when the product is a V-shaped mesh sleeve, the angles of the beginning and end of the mesh sleeve are inconsistent. When the cut piece moves on the feeding roller 210 and the auxiliary roller 230, the rotating mechanism drive 330 drives the first support plate 310 to rotate. This causes the feeding mechanism 20 and the correction mechanism 40 on the first support plate 310 to adjust their angles as the rotating platform rotates. This causes the cut piece on the feeding roller 210 and the auxiliary roller 230 to adjust its angle as well. The rotating platform stops working when the angle is adjusted to make the sewing angles of the beginning and end of the sleeve consistent. This results in a high degree of matching between the starting and ending stitches of the V-shaped sleeve, improving the stability of the sewing and enhancing the product quality.

[0057] See Figure 1 and 5As shown, the correction mechanism 40 is mounted on the first support plate 310, located in the lower region between the feeding roller 210 and the auxiliary roller 230. The correction mechanism 40 includes a correction mechanism drive 410, a connector 420, a correction link 430, an auxiliary link 440, and a fixed base 450. The correction mechanism drive 410 provides driving force for the operation of the correction mechanism 40. The connector 420 is movably connected to the correction mechanism drive 410 and can rotate under the drive of the correction mechanism drive 410, transmitting the driving force provided by the correction mechanism drive 410 to the correction link 430 and the auxiliary link 440, causing the correction link 430 and the auxiliary link 440 to move simultaneously. The correction link 430 includes a first end and a second end, wherein the first end is movably connected to the connector 420, and the second end is used for… The second end of the correction link 430 contacts the cut piece; when the second end contacts the cut piece, the friction causes the correction link 430 to move, thus correcting the cut piece's deviation. One end of the auxiliary link 440 is movably connected to the correction link 430, and this end moves with the correction link 430. The other end of the auxiliary link 440 is movably connected to the fixed base 450, and this end is fixed in position and does not move with the correction link 430, thus limiting the movement path of the correction link 430. The control mechanism is electrically connected to the correction mechanism drive 410.

[0058] When the correction mechanism 40 is in operation, the correction mechanism drive 410 drives the connector 420, correction link 430, and auxiliary link 440 to rotate. Under the joint constraint of the connector 420 and auxiliary link 440, the second end of the correction link 430 exhibits a periodic reciprocating motion to simulate the action of a human hand pushing the cut piece in one direction, thereby driving the cut piece to move in the opposite direction of the offset direction. Furthermore, during the periodic reciprocating motion of the second end of the correction link 430, it contacts the cut piece at regular intervals, intermittently pushing the cut piece to move. This completes the correction of the cut piece without affecting its normal operation, eliminating the need for operator intervention. This achieves automation and precision in the correction process, improving the efficiency of the correction procedure and ensuring high safety performance.

[0059] See Figure 1 and Figure 6As shown, the adjusting mechanism 50 is located on the side of the auxiliary roller 230 away from the feeding roller 210. The adjusting mechanism 50 includes a second lead screw module 510, which is connected to the auxiliary roller 230. The second lead screw module 510 drives the auxiliary roller 230 to move in the left-right direction, automatically adjusting the gap between the feeding roller 210 and the auxiliary roller 230, thereby adjusting the tension of the cut pieces to accommodate cut pieces of different sizes, such as mesh sleeve cut pieces of different diameters. This eliminates the need for manual adjustment of the cut piece tension, saving manpower. The control mechanism is electrically connected to the second lead screw module 510.

[0060] See Figure 1 As shown, the sewing mechanism 60 is mounted on the machine platform for sewing fabric pieces. The control mechanism is electrically connected to the sewing mechanism 60.

[0061] In some embodiments, the automatic sewing device for mesh sleeves also includes a sewing platform 610, which has a sewing table surface. The sewing platform 610 is mounted on the machine base and located below the sewing head of the sewing mechanism 60. The sewing table surface is opposite to the sewing needle of the sewing head. The feeding roller 210 and the auxiliary roller 230 are located on both sides of the sewing platform 610, respectively.

[0062] The above-mentioned knitted crew neck sweater mesh sleeve sewing device achieves the purpose of improving the sewing effect by setting a sewing platform 610. Since the sewing platform 610 is located between the feeding roller 210 and the auxiliary roller 230, when the feeding roller 210 feeds material and the auxiliary roller 230 cooperates in feeding material, there is no need for manual assistance in fixing the cut pieces on the sewing platform 610, thus saving manpower.

[0063] In some implementations, see Figure 1 and Figure 7 As shown, the automatic sewing device for mesh sleeves also includes a stop-fixing mechanism 70. The stop-fixing mechanism 70 includes a stop-fixing arm 710 and a stop-fixing drive member 730. A first end of the stop-fixing arm 710 is connected to the stop-fixing drive member 730, and a second end of the stop-fixing arm 710 is bent to a bend 720 extending towards the first end. The length of the bend 720 is equal to the width of the stop of the fabric piece. A control mechanism is electrically connected to the stop-fixing drive member 730.

[0064] The aforementioned automatic sewing device for mesh sleeves achieves the fixation of the cut piece's stop by setting a stop fixing mechanism 70. Specifically, before the cut piece is fitted onto the feeding roller 210 and the auxiliary roller 230, the stop fixing drive 730 drives the stop fixing arm 710 forward to be positioned between the feeding roller 210 and the auxiliary roller 230. After the cut piece is fitted onto the feeding roller 210 and the auxiliary roller 230, the stop fixing drive 730 drives the stop fixing arm 710 to reset. The bent portion 720 of the stop fixing arm 710 can hook the stop of the cut piece. Since the length of the bent portion 720 is equal to the width of the cut piece's stop, the stop fixing mechanism 70 can maintain the width of the cut piece's stop without changing as the cut piece moves forward, thus achieving the purpose of fixing the stop.

[0065] In some implementations, see Figure 1 and Figure 8 As shown, the automatic sewing device for mesh sleeves also includes a positioning mechanism 80, which is located on the machine platform and includes a positioning plate 810. The positioning plate 810 is located between the feeding roller 210 and the auxiliary roller 230 for positioning the edge of the cut piece.

[0066] In some embodiments, the adjacent adjustment mechanism further includes a sensor 820, which is electrically connected to the control mechanism. The control mechanism controls the adjacent adjustment mechanism 10 to move according to the position signal of the sensor 820.

[0067] In some implementations, the control mechanism includes a control panel 900. The control panel 900 is mounted on the machine base and enables human-machine interaction. Workers can input relevant process control parameters through the control panel 900. The control panel 900 is also used to display relevant operating data of the automatic mesh sleeve sewing device.

[0068] A sewing method using an automatic mesh sleeve sewing device for sewing cuff pieces includes the following steps:

[0069] The cut piece is placed on the feeding roller 210 and the auxiliary roller 230. The control mechanism controls the pressing drive 120 to drive the pressing roller 110 to move onto the feeding roller 210. The control mechanism controls the feeding drive 220 to drive the feeding roller 210 to rotate, thereby driving the pressing roller 110 to rotate. The feeding roller 210 and the pressing roller 110 cooperate to drive the cut piece to move.

[0070] Before the cut piece is fitted onto the feeding roller 210 and the auxiliary roller 230, the control mechanism controls the stop fixing drive 730 to drive the stop fixing arm 710 forward to the space between the feeding roller 210 and the auxiliary roller 230. After the cut piece is fitted onto the feeding roller 210 and the auxiliary roller 230, the control mechanism controls the stop fixing drive 730 to drive the stop fixing arm 710 to reset. The bent portion 720 of the stop fixing arm 710 can hook the stop of the cut piece. Since the length of the bent portion 720 is equal to the width of the stop of the cut piece, the stop fixing arm 710 can keep the width of the stop of the cut piece unchanged when the cutting piece feeding roller 210 and the auxiliary roller 230 move, thus achieving the purpose of fixing the stop.

[0071] When the cut piece moves between the feeding roller 210 and the auxiliary roller 230, the control mechanism controls the correction drive to drive the correction link 430 to move. Since the second end of the correction link 430 simulates the action of a human hand to push the cut piece in one direction, it contacts the cut piece at regular intervals and intermittently pushes the cut piece to move in the opposite direction of the offset direction, thus completing the correction of the cut piece without affecting the normal operation of the cut piece.

[0072] The control mechanism controls the sewing mechanism to sew the cut pieces.

[0073] When the positional relationship between the cut piece and the sewing mechanism 60 needs to be adjusted, the control mechanism controls the rotating mechanism drive 330 to drive the first support plate 310 to rotate, thereby driving the feeding mechanism 20 to rotate so that the cut piece rotates by a predetermined angle.

[0074] When the tension of the cut piece needs to be adjusted, the control mechanism controls the second lead screw module 510 to drive the auxiliary rolling element 230 to move in the left and right direction, adjust the interval between the auxiliary rolling element 230 and the feeding rolling element 210, and thus adjust the tension of the cut piece to adapt to cut pieces of different sizes.

[0075] The aforementioned automatic sewing device for mesh sleeves uses a pressure-pressing drive 120 to move the pressure-pressing roller 110 onto the feeding mechanism 20. The feeding mechanism 20 is controlled to rotate, causing the pressure-pressing roller 110 to rotate. The feeding mechanism 20 and the pressure-pressing roller 110 work together to move the cut piece. A correction drive 430 is controlled to rotate, causing the cut piece to move in the opposite direction of the offset direction, thus correcting the cut piece's deviation during sewing. The sewing mechanism 60 is controlled to sew the cut piece. When the positional relationship between the cut piece and the sewing mechanism 60 needs adjustment, the rotating mechanism 30 is controlled to rotate, causing the feeding mechanism 20 to rotate, resulting in a predetermined angle rotation of the cut piece. When the tension of the cut piece needs adjustment, the adjusting mechanism 50 is controlled to drive the auxiliary roller 230 to move in the left-right direction, promptly adjusting the interval between the auxiliary roller 230 and the feeding roller 210.

[0076] The automatic sewing device for net sleeves on the market enables the cutting piece, which is mounted on the feeding roller 210, to move along the front and back direction by setting the first screw module 130 in the edge control mechanism 10, so that the cutting piece is always kept within a certain appropriate range and the sewing quality is guaranteed.

[0077] The above-mentioned automatic sewing device for mesh sleeves drives the auxiliary rolling element 230 to move in the left and right directions through the second screw module 510 set in the adjustment mechanism 50, and adjusts the interval between the auxiliary rolling element 230 and the feeding rolling element 210 in a timely manner, so that the device can be applied to cut pieces of different sizes.

[0078] The above-mentioned automatic sewing device for mesh sleeves achieves the purpose of fixing the stop of the cut piece by setting a stop fixing mechanism 70. The bent part 720 of the stop fixing arm 710 can hook the stop of the cut piece. Since the length of the bent part 720 is equal to the width of the stop of the cut piece, the stop fixing mechanism 70 can keep the width of the stop of the cut piece from changing when the cut piece moves forward, thus achieving the purpose of fixing the stop.

[0079] The above-mentioned automatic sewing device for mesh sleeves achieves the purpose of positioning the edge of the cut piece by setting a positioning mechanism 80. The positioning mechanism 80 includes a positioning plate 810, which is located between the feeding roller 210 and the auxiliary roller 230 for positioning the edge of the cut piece.

[0080] The aforementioned automatic mesh sleeve sealing device improves the sewing effect by setting up a sewing platform 610. Since the sewing platform is located between the feeding roller 210 and the auxiliary roller 230, when the feeding roller 210 and the auxiliary roller 230 work together to feed the material, there is no need for manual assistance in fixing the cut pieces on the sewing platform 610, saving manpower and improving production efficiency.

[0081] The aforementioned automatic sewing device for mesh sleeves, through the rational distribution of multiple mechanisms such as the multi-edge control mechanism 10, the feeding mechanism 20, the rotating mechanism 30, and the correction mechanism 40, achieves automation, high production efficiency, and high quality stability in the sewing process through the efficient cooperation and coordination among these multiple mechanisms.

9. A sewing method, characterized in that, Includes the following steps: The cut piece is placed on the feeding mechanism, and the pressing drive is controlled to drive the pressing roller to move onto the feeding mechanism. The feeding mechanism is controlled to move so as to drive the pressing roller to rotate. The feeding mechanism and the pressing roller cooperate to drive the cut piece to move. During the sewing process, the correction drive in the correction mechanism drives the correction linkage to rotate, thereby driving the cut piece to move in the opposite direction of the offset direction. Control the sewing mechanism to sew the cut pieces; When the positional relationship between the cut piece and the sewing mechanism needs to be adjusted, the rotating mechanism is controlled to rotate, which drives the feeding mechanism to rotate, causing the cut piece to rotate by a predetermined angle. When the tension of the cut piece needs to be adjusted, the adjustment mechanism drives the auxiliary rolling element to move in the left and right directions. The rotating mechanism includes a first support plate and a rotating mechanism drive. The first support plate is used to support the feeding mechanism, the correction mechanism and the adjustment mechanism. The rotating mechanism drive is used to drive the first support plate to rotate so that the cut piece rotates by a predetermined angle. The correction mechanism further includes a connector, an auxiliary link, and a fixed base; the connector is connected to the correction mechanism drive and one end of the correction link, and is used to transmit the driving force provided by the correction mechanism drive to the correction link and the auxiliary link; one end of the auxiliary link is connected to the correction link, and the other end is connected to the fixed base, so as to limit the movement path of the correction link; the other end of the correction link is used to contact the cut piece to drive the cut piece to move in the opposite direction of the offset direction.
