Description

Technical Field

[0001] This invention relates to the technical field of clothing, specifically to an integrated device for intelligent cutting and automatic alignment sewing of clothing. Background Technology

[0002] An integrated intelligent garment cutting and automatic alignment and sewing device combines the fabric cutting process with the pattern sewing process on a single machine, enabling continuous operation in garment processing. This device allows for the sequential cutting of fabric and the alignment and sewing of pattern pieces under operator control, reducing the handling and secondary positioning steps required in traditional separate equipment. Suitable for small-batch customization or mass production of various garments, it helps shorten the processing flow, maintains the neatness of pattern edges and the consistency of sewing positions, and has wide applications in garment processing workshops and training facilities.

[0003] However, this conventional device has the following problems in practical applications: First, during the garment cutting process, the fabric is subjected to the downward pressure or traction of the cutting knife on the cutting table, which can easily cause local wrinkles or displacement, resulting in uneven edges of the cut pieces. When wrinkles appear, the cutting knife cuts along the preset trajectory, and the actual cut outline deviates from the design pattern. The edges of the cut pieces are wavy or serrated, affecting the alignment accuracy during subsequent sewing. Secondly, in the process of garment cutting, in order to ensure cutting accuracy, it is necessary to apply a certain amount of pressure or fixation around the fabric. Existing ordinary cutting devices usually use multi-point presser feet or manual clamps to fix the edges of the fabric. When cutting different shapes or sizes of cut pieces, it is necessary to repeatedly disassemble and reassemble the pressing parts or adjust the position of the clamps. The process is cumbersome and time-consuming. Frequent adjustments not only reduce work efficiency, but also easily cause local fabric to be loose or too tight due to uneven distribution of fixing points, affecting the cutting quality. Furthermore, during the fabric sewing process, the multiple layers of fabric fed into the sewing area are prone to relative slippage due to different frictional resistance or uneven feeding speed. This can lead to misalignment or skewing of the edges of the upper and lower layers of fabric after sewing. Skewed seams will make the fabric joints uneven, affecting the alignment accuracy of subsequent processes and the overall processing quality. Skewed cut pieces are difficult to restore with simple corrections, increasing rework rate and material waste. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated intelligent garment cutting and automatic alignment sewing device, which can solve the following problems: Fabric is prone to wrinkles during cutting, resulting in uneven edges; the process of fixing and adjusting before cutting is cumbersome; and the fabric is prone to tilting during sewing.

[0005] To solve the above-mentioned technical problems, the present invention proposes the following technical solution: An integrated intelligent garment cutting and automatic alignment sewing device includes a worktable, a support fixedly connected to the bottom of the worktable, an electric push rod fixedly installed on both sides of the top rear of the worktable, a fourth motor fixedly connected inside the worktable, a machine box fixedly connected to both sides of the top of the worktable, and a fixing box fixedly connected to the top of the machine box. A second motor is fixedly installed inside the casing. A lead screw is fixedly connected to the output end of the first motor. A slider is movably connected to the outer surface of the lead screw. A second motor is fixedly installed on the outer surface of the slider. A cutting blade is fixedly connected to the output end of the second motor. A fixed base is fixedly connected to the lower part of the outer surface of the slider. A second spring is fixedly connected inside the fixed box. A movable plate is fixedly connected to the top of the second spring. A third motor is fixedly installed on the top of the movable plate. A rotating rod is fixedly connected to the output end of the third motor. Movable blocks are fixedly connected to both sides of the outer surface of the rotating rod. An upper fixing strip is fixedly connected to the back of the rotating rod. A first spring is fixedly connected to the lower back of the upper fixing strip. A lower fixing strip is fixedly connected to the outer surface of the first spring. An adjusting block is fixedly connected to the output end of the electric push rod, a limit plate is fixedly connected to one side of the adjusting block, a wheel set is fixedly connected to the output end of the fourth motor, a rotating component is fixedly connected to the outer surface of the wheel set, a movable rod is movably connected to the outer surface of the rotating component, and a gravity block is movably connected to the bottom of the outer surface of the movable rod.

[0006] Furthermore, the slider is movable from left to right on the outer surface of the lead screw, and the cutting blade is rotated inside the fixed seat.

[0007] Furthermore, the movable block is rotated counterclockwise by a rotating rod, and the bottom of the movable block is provided with an arc-shaped protrusion, the bottom of the movable block abutting against the top of the casing.

[0008] Furthermore, a vertical through groove is provided on one side of the fixing box, and the rotating rod is moved up and down within the through groove of the fixing box.

[0009] Furthermore, the upper fixing strip and the lower fixing strip are arranged overlappingly, and the lower fixing strip is arranged to move from top to bottom on the back of the housing.

[0010] Furthermore, the upper rotating bar, fixed bar, lower rotating bar, movable bar, and movable block are interconnected via a rotating shaft.

[0011] Furthermore, the limiting plate is moved from bottom to top by an electric push rod, and the limiting plate is located behind the wheel assembly.

[0012] Furthermore, there are four wheel sets and four fourth motors, arranged in two groups of two, with each group of four fourth motors and wheel sets symmetrically arranged on the horizontal plane of the worktable.

[0013] Furthermore, the upper wheel set and the lower wheel set are arranged to rotate in the same direction, while the two sets of wheel sets are arranged to rotate in opposite directions.

[0014] Furthermore, the movable rod is inclined to one side of the outer surface of the wheel assembly, and the gravity block abuts against the top of the workbench.

[0015] As can be seen from the above technical solution, the beneficial effects of the present invention are as follows: 1. In this invention, after the fabric is placed at the bottom of the machine box, before cutting, the movable block rotates to make the protrusion rotate, which drives the upper fixing strip to move downwards. This, in conjunction with the lower fixing strip, firmly fixes one end of the fabric, preventing the fabric from shifting or wrinkling during the cutting process. Subsequently, the first motor drives the lead screw to rotate, causing the slider to move. The second motor starts, causing the fixing seat to fit against the top of the fabric. The cutting blade cuts while the fabric is compressed. This structure achieves effective tension and positioning of the fabric before cutting, avoiding local wrinkles caused by the downward pressure or traction of the cutting blade. It ensures that the edges of the fabric are even after cutting, improves the cutting accuracy, and reduces material waste and subsequent trimming processes caused by unevenness.

[0016] 2. In this invention, after cutting, the fabric is pulled forward to below the limiting plate. A fourth motor drives the wheel set to rotate in the opposite direction, stretching both ends of the fabric to automatically flatten it. An electric push rod pushes the limiting plate downwards to fix the fabric, ensuring it remains flat during sewing. When the sewing machine is sewing the fabric, adjusting the rotation direction of the wheel set allows the moving rod to move synchronously with the rotation direction. The gravity block presses down on the wrinkles generated in the sewing area in real time, effectively preventing relative slippage and skewing of multiple layers of fabric due to different frictional resistance or uneven feeding speeds during sewing. This structure ensures that the edges of the upper and lower layers of fabric are aligned and flat after sewing, improving sewing accuracy and splicing quality, and reducing rework and material waste caused by skewing.
