Description

Technical Field

[0001] The invention relates to the field of clothing production equipment, and in particular to a rolling clamp for clothing pattern making and a moving method thereof. Background Art

[0002] Clothing pattern making is a key step in the clothing design and production process. It is the process of converting the designer's two-dimensional design drawings into three-dimensional objects. Through pattern making, the feasibility of the design can be ensured and the actual effect of the design can be presented. During the pattern making process, samples of different sizes need to be made according to different size standards to meet the needs of different consumers. This step is crucial to ensure the fit of the clothing. At the same time, pattern making and sample making before mass production can discover and solve design or process problems, avoid errors in mass production, and thus save production costs. Clothing pattern making is a bridge connecting design and production, and is of great significance for realizing design concepts, ensuring product quality, and improving production efficiency.

[0003] Currently, in the process of pattern making and sample making, since the fabric is laid flat on the cutting table and cut according to the layout, and the fabric is pressed tightly using fixed clamps on the four sides of the cutting table, the cutting seam position is prone to shrinkage, wrinkles, warping and other displacements during the fabric cutting process due to the disappearance of the fabric tension state, which can easily affect the accuracy of the subsequent cutting position. In addition, the current fabric cutting clamps can only clamp the four sides of the fabric, and the cut cutting seam position cannot be pressed, and the cutting pressure exerted by the cutter on the fabric can easily push the fabric, further aggravating the problem of the offset of the fabric cutting position during the cutting process. Summary of the invention

[0004] The purpose of the present invention is to provide a rolling clamp for clothing pattern making and a moving method thereof in order to solve the above-mentioned problems. Two sets of rolling clamps are arranged on both sides of the cutting part serving as a cutter. The universal wheels pressed to the top surface of the cloth can ensure that the cloth on both sides of the cut can be stably pressed to the surface of the cutting table, thereby improving the offset problem of the cloth cutting position and improving the consistency between the actual cut and the pattern. In addition, a negative pressure fan is used to adsorb both sides of the cloth cut to the top surface of the cutting table, thereby further improving the flatness of the cloth cutting position.

[0009] Preferably, the bottom output end of the operating motor is fixedly connected to the mounting plate, and a fixing plate is provided on the outside of the operating motor, and the operating motor is installed behind the longitudinal slide seat through the fixing plate. The outside of the top air inlet of the negative pressure fan is connected to an exhaust joint, and the exhaust joint is flush with the bottom side of the cutting table.

[0010] The top end of the driving mechanism is fixed with a toothed wheel, and the bottom end of the driving mechanism is fixed with a toothed wheel, and the toothed wheel is connected with the toothed wheel by a toothed wheel.

[0011] Preferably, a longitudinally extending fixed rack is provided on one side below the longitudinal frame, connecting bolts for fixing the longitudinal frame are passed through both ends of the fixed rack, and a longitudinally extending movable rack is fixed on the bottom side of the longitudinal slide away from the fixed rack.

[0013] Preferably, the transverse shift assembly includes a transversely extending cross frame, both ends of which are fixed with supports extending downward and fixed to the outside of the cutting table, a transversely extending screw is rotatably arranged in the middle of the cross frame, and a transverse shift motor supporting the rotation of the screw is fixed to the outside of the support, the transverse slide is in transverse sliding cooperation with the cross frame, and a downwardly extending pressure ear is fixed to the bottom of the support.

[0014] Preferably, the transverse slide is threadably matched with the screw rod, and the length of the transverse frame is equal to the length of the cutting table.

[0016] The method for moving the rolling fixture for garment pattern making comprises the following steps:

[0017] a. When the fabric needs to be cut according to the layout to make a sample garment, the fabric is spread out on the top side of the cutting table, and the layout is placed on the top surface of the fabric. A cutting track is drawn along the edge of the layout, and then the layout is removed. Subsequently, the fabric is cut into shape along the cutting track using the cutting unit;

[0018] b. Use the transverse motor to drive the screw to rotate, and through the screw and the thread of the transverse slide, support the transverse slide to move transversely on the inside of the transverse frame, change the transverse position of the transverse slide and its rear connecting parts, so as to adjust the transverse position of the cutting part accordingly. At the same time, use the positioning cylinder fixed on the front side of the transverse slide to support the driving gear to move forward and backward. During the movement of the telescopic end of the positioning cylinder, the driving gear pushes the movable rack to slide longitudinally. At the same time, since the fixed rack is in a fixed state, the driving gear rotates through the support of the fixed rack during the forward and backward movement, so as to use the rotation of the driving gear to further promote the movement of the movable rack, so as to expand the moving stroke of the telescopic end of the positioning cylinder and realize the stroke amplification function;

[0019] c. When the direction of the cutting part needs to be adjusted according to the cutting track, the output end of the operating motor is rotated to drive the mounting plate and the cutting part on the bottom side to rotate, so as to meet the steering function of the cutting part. At the same time, the mounting plate rotates to ensure that the two sets of rolling clamps are always located on both sides of the cutting track to press the two sides of the cutting seam to ensure the flatness of the cutting position of the fabric and avoid the cutting part from lifting the fabric or deviating the fabric position;

[0020] d. When the operating motor drives the mounting plate and the cutting part to adjust the cutting direction, the upper synchronous belt is used to synchronize the rotation of the output end of the operating motor with the transmission shaft, and the lower synchronous belt is used to rotate the transmission shaft and the auxiliary shaft synchronously, so as to ensure that the two sets of negative pressure fans at both ends of the bracket are always consistent with the positions of the two sets of rolling clamps on the mounting plate. The negative pressure fan draws air downward through the exhaust joint to stably adsorb the corresponding position of the cloth to the top side of the cutting table through the adsorption holes of the cutting table, so that after changing the cutting direction, the pressure on both sides of the cut seam and the adsorption and adhesion state on the cutting table can be maintained, so as to realize the synchronous following of the pressure and adsorption position with the cutting position.

[0021] The beneficial effects are as follows: 1. The present invention arranges two sets of rolling clamps on both sides of the cutting part as a cutter, and ensures that the fabric on both sides of the cut can be stably pressed to the surface of the cutting table by the universal wheels pressed to the top surface of the fabric, thereby avoiding the disadvantage that the traditional four-side clamps cannot press the actual cutting position during the fabric cutting process, improving the deviation problem of the fabric cutting position, and improving the consistency between the actual cut and the layout;

[0022] In addition, a bracket and two sets of negative pressure fans are arranged under the synchronous frame, and the negative pressure fans corresponding to the rolling clamps are used to adsorb the two sides of the fabric cut seam to the top surface of the cutting table, so as to further improve the flatness of the fabric cutting position and the stability of the fabric cut seam position after cutting. At the same time, the synchronous frame is used to keep the cutting part, the bracket and the mounting plate rotating synchronously, so as to ensure that the rolling clamp and the negative pressure fan can follow the cutting part and always be located on both sides of the cut seam, so as to improve the cutting accuracy;

[0023] 3. At the same time, a fixed rack is set to cooperate with a movable rack and a driving gear to form a stroke amplification mechanism. When the positioning cylinder pushes the driving gear to move longitudinally, the fixed rack supports the driving gear to rotate, so that the driving gear supports the movable rack to slide longitudinally, thereby realizing the stroke amplification function, meeting the needs of cutting larger sizes of fabrics, and being more convenient to use.

[0045] A positioning cylinder 5 is fixed to the front side of the transverse slide 3 for pushing the longitudinal slide 4 to move forward and backward, a longitudinal frame 301 supporting the sliding of the longitudinal slide 4 is fixed to the bottom side of the transverse slide 3, the synchronous frame 8 is a U-shaped frame with an opening facing forward, the top of the synchronous frame 8 is fixed to the bottom side of the longitudinal slide 4, and the output end of the operating motor 7 vertically penetrates the synchronous frame 8 and is in clearance with the synchronous frame 8, a driving pulley 701 is coaxially fixed to the output end of the operating motor 7 above the synchronous frame 8, a transmission shaft 801 is vertically penetrated by the rear side of the synchronous frame 8, an upper pulley 801a is arranged on the top of the transmission shaft 801, and a transmission connection is provided between the upper pulley 801a and the driving pulley 701 The upper synchronous belt 802 and the bottom end of the synchronous frame 8 are rotatably provided with an auxiliary shaft 804 fixedly connected to the bracket 9, the bottom end of the auxiliary shaft 804 is fixed with an auxiliary pulley 804a, and the bottom end of the transmission shaft 801 is fixed with a lower pulley 801b, and the lower synchronous belt 803 is connected between the lower pulley 801b and the auxiliary pulley 804a, and the two sets of synchronous belts are used to synchronize the rotation of the mounting plate 6 and the bracket 9, so that when the cutting part 10 on the bottom side of the mounting plate 6 rotates according to the cutting trajectory, the mounting plate 6 and the bracket 9 can be rotated synchronously, so that the two sets of rolling clamps 15 and the two sets of negative pressure fans 14 are synchronously distributed to the two sides of the cutting seam.

[0046] A longitudinally extending fixed rack 302 is provided at one side below the longitudinal frame 301, and connecting bolts 303 are penetrated at both ends of the fixed rack 302 to fix the longitudinal frame 301. A longitudinally extending movable rack 401 is fixed to the side of the bottom of the longitudinal slide 4 away from the fixed rack 302. The telescopic end of the positioning cylinder 5 extends backward between the fixed rack 302 and the movable rack 401, and a rotating frame is fixed to the telescopic end of the positioning cylinder 5.

[0049] The method for moving a rolling fixture for garment pattern making comprises the following steps:

[0050] a. When the fabric needs to be cut according to the layout to make a sample garment, the fabric is spread out on the top side of the cutting table 1, and the layout is placed on the top surface of the fabric, a cutting track is drawn along the edge of the layout, and then the layout is removed, and the fabric is subsequently cut and shaped correspondingly using the cutting unit 10 along the cutting track;

[0051] b. Use the lateral movement motor 202 to drive the screw rod 203 to rotate, and through the screw rod 203 and the threaded cooperation of the lateral slide 3, support the lateral slide 3 to move laterally inside the horizontal frame 201, change the lateral position of the lateral slide 3 and its rear connecting parts, so as to adjust the lateral position of the cutting part 10 accordingly, and at the same time use the positioning cylinder 5 fixed on the front side of the lateral slide 3 to support the driving gear 502 to move forward and backward. During the movement of the driving gear 502 following the telescopic end of the positioning cylinder 5, the driving gear 502 pushes the movable rack 401 to slide longitudinally. At the same time, since the fixed rack 302 is in a fixed state, the driving gear 502 rotates during the forward and backward movement through the support of the fixed rack 302, so as to use the rotation of the driving gear 502 to further promote the movement of the movable rack 401, so as to expand the moving stroke of the telescopic end of the positioning cylinder 5, and realize the stroke amplification function;

[0052] c. When the direction of the cutting part 10 needs to be adjusted according to the cutting track, the output end of the operating motor 7 is rotated to drive the mounting plate 6 and the cutting part 10 at the bottom to rotate, so as to meet the steering function of the cutting part 10. At the same time, the mounting plate 6 rotates to ensure that the two sets of rolling clamps 15 are always located on both sides of the cutting track to press the two sides of the cutting seam to ensure the flatness of the cutting position of the cloth and prevent the cutting part 10 from lifting the cloth or deviating from the cloth position;

[0053] d. When the operating motor 7 drives the mounting plate 6 and the cutting part 10 to adjust the cutting direction, the upper synchronous belt 802 is used to synchronize the rotation of the output end of the operating motor 7 with the transmission shaft 801, and the lower synchronous belt 803 is used to synchronize the transmission shaft 801 with the auxiliary shaft 804 to ensure that the two groups of negative pressure fans 14 at both ends of the bracket 9 are always in the same position as the two groups of rolling clamps 15 on the mounting plate 6. The negative pressure fan 14 exhausts air downward through the exhaust joint 14a to stably adsorb the corresponding position of the cloth to the top side of the cutting table 1 through the adsorption holes 101 of the cutting table 1, so that after changing the cutting direction, the pressure on both sides of the cut seam and the adsorption and adhesion state on the cutting table can be maintained, so as to achieve the synchronous following of the pressure and adsorption position with the cutting position.

[0054] Two sets of rolling clamps 15 are arranged on both sides of the cutting part 10 as a cutter, and the universal wheels 15c pressed against the top surface of the cloth ensure that the cloth on both sides of the cut can be stably pressed against the surface of the cutting table 1, thereby avoiding the disadvantage that the traditional four-side clamps cannot press the actual cutting position during the cloth cutting process, improving the deviation problem of the cloth cutting position, and improving the consistency between the actual cut and the layout;

[0055] In addition, a bracket 9 and two sets of negative pressure fans 14 are arranged under the synchronous frame 8, and the negative pressure fans 14 corresponding to the rolling clamps 15 are used to adsorb the two sides of the fabric cut seam to the top surface of the cutting table 1, so as to further improve the flatness of the fabric cutting position and the stability of the fabric cut seam position after cutting. At the same time, the synchronous frame 8 is used to keep the cutting part 10, the bracket 9 and the mounting plate 6 rotating synchronously, so as to ensure that the rolling clamps 15 and the negative pressure fans 14 can follow the cutting part 10 and are always located on both sides of the cut seam, so as to improve the cutting accuracy;

[0056] At the same time, a fixed rack 302 is arranged to cooperate with the movable rack 401 and the driving gear 502 to form a stroke amplification mechanism. When the positioning cylinder 5 pushes the driving gear 502 to move longitudinally, the fixed rack 302 supports the driving gear 502 to rotate, so that the movable rack 401 is supported to slide longitudinally through the driving gear 502, thereby realizing the stroke amplification function, meeting the needs of cutting larger sizes of cloth, and being more convenient to use.

[0057] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
