Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to an automatic sewing and bartacking machine for webbing bulges. Background Technology

[0002] Bar-stitching is a common garment processing technique, primarily used to reinforce stress-bearing parts of clothing, such as pocket openings and trouser loops. Traditional bar-stitching typically relies on manual placement and movement of the webbing. Operators manually feed the webbing to the sewing machine needle and control the sewing position based on experience. This method is not only labor-intensive and inefficient, but also prone to problems such as needle position deviation, uneven stitches, webbing wrinkling, or shifting due to the subjectivity and instability of manual operation, severely impacting product quality consistency.

[0003] Although some automated equipment has attempted to replace manual operation in the existing technology, such as using simple clamps in conjunction with linear movement mechanisms to achieve webbing displacement, there are still defects such as insecure clamping, inaccurate positioning, easy slippage of the webbing or wrinkles, which cannot meet the requirements of high-quality sewing and bar stitching.

[0004] Therefore, there is an urgent need for a fully automated, high-precision, and highly stable bar stitching machine to improve production efficiency and product quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic tack stitching machine for webbing bulges, which solves the problems of low efficiency and unstable quality caused by reliance on manual operation in existing technologies, and realizes the automation of the entire tack stitching process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic bartacking and sewing machine for webbing includes a frame, a bartacking sewing machine head and a sewing table mounted on the frame. A moving device is installed on one side of the sewing table, and a sewing positioning plate and a pressing device are installed on the moving device. The sewing positioning plate and the pressing device are both connected to the moving device and driven by it to move in the XY direction. A sewing pressure plate is installed on the pressing device, and the sewing pressure plate is driven by the pressing device to open and close relative to the sewing positioning plate to clamp or release the webbing.

[0008] Furthermore, a sewing station is provided on the upper surface of the sewing positioning plate, and the sewing station is recessed within the surface of the sewing positioning plate.

[0009] Furthermore, two sets of telescopic bulging devices are installed on the upper part of the sewing positioning plate; the bulging device includes a telescopic cylinder and a bulging telescopic block, the telescopic cylinder is located on the sewing positioning plate, and the bulging telescopic block is connected to the output end of the telescopic cylinder and is driven by the telescopic cylinder to reciprocate towards the sewing station; the front end of the bulging telescopic block has a beveled structure.

[0010] Furthermore, the pressing device includes a slide rail, a slider movably connected to the slide rail, and a driving mechanism for driving the slider to move linearly along the slide rail; a connecting plate is mounted on the slider, and the sewing press plate is connected to the bottom of the connecting plate.

[0011] Furthermore, two sets of opposing positioning and clamping devices are installed on the upper surface of the sewing table; each positioning and clamping device includes a transmission cylinder, a positioning and clamping block, a swing block, and a mounting base; the transmission cylinder is located on the mounting base, the positioning and clamping block is located at the front end of the swing block, the rear end of the swing block is hinged to the mounting base via a rotating shaft, a sliding groove is provided in the middle of the swing block, a shaft-shaped component passes through the sliding groove, a transmission block perpendicular to the shaft-shaped component is connected to the shaft-shaped component, and the transmission block is connected to the output end of the transmission cylinder; the positioning and clamping block is driven by the transmission cylinder to fix the webbing.

[0012] Furthermore, the bottom surface of the positioning clamping block is provided with a toothed structure.

[0013] Furthermore, the sewing press plate has a through-type cutting groove, which corresponds to the sewing station.

[0014] Furthermore, the bottom surface of the sewing press plate is provided with a toothed structure.

[0015] Compared with existing technologies, the technical solution of this patent has the following advantages:

[0016] 1. By using a moving device to drive the sewing positioning plate and pressing device to move in the XY directions, the manual placement of the webbing is replaced, significantly improving production efficiency; ensuring accurate needle position for each bar stitch, eliminating human error, and guaranteeing product consistency. The coordinated clamping of the sewing presser plate and sewing positioning plate effectively prevents the webbing from shifting or sliding during sewing.

[0017] 2. By designing a bulging device, before the webbing is pressed tight by the sewing presser plate, the bulging telescopic block extends into the sewing station first, inserting between the upper and lower layers of webbing, causing the upper layer of webbing to bulge. At the same time, the bulging telescopic block presses the lower layer of webbing together. Because the front end of the bulging telescopic block has a beveled structure, when the bulging telescopic block extends, it can quickly insert between the upper and lower layers of webbing, creating a gap or space between the two layers of webbing. This ensures that the subsequent stitches of the sewing machine needle can firmly penetrate and connect the upper and lower layers of webbing.

[0018] 3. By using a positioning and clamping device to temporarily fix the webbing during the repositioning process, continuous automated operation can be achieved, improving the consistency and reliability of the overall process. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] See Figures 1-6As shown, this embodiment provides an automatic bartacking machine for webbing, including a frame 1, a bartacking sewing head 2 and a sewing table 3 mounted on the frame 1. A moving device 4 is mounted on one side of the sewing table 3, and a sewing positioning plate 5 and a pressing device 6 are mounted on the moving device 4. The sewing positioning plate 5 and the pressing device 6 are both connected to the moving device 4 and driven by it to move in the XY direction. A sewing pressure plate 7 is mounted on the pressing device 6, and the sewing pressure plate 7 is driven by the pressing device 6 to open and close relative to the sewing positioning plate 5 to clamp or release the webbing 10. The moving device 4 replaces the traditional manual placement and movement of the webbing, realizing the automation of the entire sewing process and greatly improving production efficiency. The positioning driven by the moving device (such as a lead screw or linear module) ensures that the needle position of each bartacking is extremely accurate, eliminating the positional deviation caused by manual operation and ensuring the consistency of product quality. The sewing pressure plate 7 and the sewing positioning plate 5 open and close relative to each other through the pressing device 6, which can firmly clamp the webbing during the sewing process and effectively prevent the webbing from shifting or sliding during the sewing process, thus fundamentally ensuring the beauty and strength of the stitches.

[0028] See Figure 1 , Figure 5 As shown, two sewing positions 51 are provided on the upper surface of the sewing positioning plate 5, and the sewing positions 51 are recessed within the surface of the sewing positioning plate 5. The recessed design of the sewing positions 51 can confine the webbing 10 to a specific area, playing a preliminary positioning and anti-movement role, and preparing for subsequent pressing and sewing. It should be noted that the webbing 10 here is formed by folding to form an upper webbing and a lower webbing.

[0029] Two sets of opposing telescopic bulging devices 8 are installed on the upper part of the sewing positioning plate 5. Each bulging device 8 includes a telescopic cylinder 81 and a bulging telescopic block 82. The telescopic cylinder 81 is located on the sewing positioning plate 5, and the bulging telescopic block 82 is connected to the output end of the telescopic cylinder 81, driven by the telescopic cylinder 81 to reciprocate towards the sewing station 51. The front end of the bulging telescopic block 82 has a beveled structure. Before the webbing 10 is pressed by the sewing pressure plate 7, the bulging telescopic block 82 first extends into the sewing station 51, inserting between the upper and lower layers of webbing, causing the upper layer of webbing to bulge. Because the front end of the bulging telescopic block 82 has a beveled structure, when the bulging telescopic block 82 extends, it can quickly insert between the upper and lower layers of webbing, creating a gap or space between the two layers. This ensures that the stitches of the subsequent sewing machine needle can firmly penetrate and connect the upper and lower layers of webbing.

[0030] The pressing device 6 includes a slide rail 61 mounted on the beam 60, a slider 62 movably connected to the slide rail 61, and a drive mechanism that drives the slider 62 to move linearly along the slide rail 61; a connecting plate 63 is mounted on the slider 62; and a sewing pressure plate 7 is connected to the bottom of the connecting plate 63. The slide rail-slider mechanism ensures the straightness and stability of the sewing pressure plate 7's movement trajectory during pressing and lifting, preventing deflection or wobbling, ensuring vertical downward pressure, and uniform clamping force. The drive mechanism, such as a cylinder, can precisely control the magnitude and stroke of the downward pressure, ensuring sufficient clamping force while avoiding excessive pressure that could damage the webbing.

[0031] See Figure 1 , Figure 6 As shown, two sets of opposing positioning clamping devices 9 are installed on the upper surface of the sewing table 3. Each positioning clamping device 9 includes a transmission cylinder 91, a positioning clamping block 92, a swing block 93, and a mounting base 94. The transmission cylinder 91 is mounted on the mounting base 94, the positioning clamping block 92 is located at the front end of the swing block 93, and the rear end of the swing block 93 is hinged to the mounting base 94 via a rotating shaft 95. A groove 931 is formed in the middle of the swing block 93, and a shaft-shaped component 97 passes through the groove 931. A transmission block 96 perpendicular to the shaft-shaped component 97 is connected to the shaft-shaped component 97, and the transmission block 96 is connected to the output end of the transmission cylinder 91. The transmission cylinder 91 drives the positioning clamping block 92 to fix the webbing. The function of the positioning clamping device 9 is to adjust the position for the next sewing and temporarily fix the webbing. The specific process is as follows: After the bar-tapping sewing machine head 2 completes the bar-tapping process at the current position of the webbing, the raised telescopic block 82 resets and exits from the webbing, but the entire webbing 10 is still pressed by the sewing pressure plate 7. The moving device 4 drives the sewing positioning plate 5 and the sewing pressure plate 7 to move towards the positioning clamping device 9. The positioning clamping device 9 is activated to press and fix the webbing 10; then, the sewing pressure plate 7 is lifted to release the pressure on the webbing 10, and the moving device 4 drives the sewing positioning plate 5 and the sewing pressure plate 7 to move horizontally away from the positioning clamping device 9. Then, the sewing pressure plate 7 presses the webbing 10 again, which completes the clamping and fixing of the webbing at the next position and the adjustment of the bar-tapping. The positioning clamping device 9 is released, and the moving device 4 moves towards the bar-tapping sewing machine head 2. After it is in place, the sewing pressure plate 7 is raised, and the raised telescopic block 82 extends in to raise the webbing. Then the sewing pressure plate 7 presses the webbing tightly. Then the bar-tapping sewing machine head 2 starts, and the moving device 4 drives the sewing positioning plate 5 and the sewing pressure plate 7 to move frequently left and right and forward at a constant speed. The bar-tapping sewing machine head 2 sews the webbing.

[0032] The bottom surface of the positioning clamping block 92 is provided with a toothed structure, which can greatly increase the friction between the clamping block and the webbing, and can also appropriately reduce the required downward pressure, while also being able to bite the webbing.

[0033] The sewing presser plate 7 has two through-type seam slots 71, each corresponding to a sewing station 51. The seam slots 71 provide ample space for the needle of the bar-stitching machine head 2 without interfering with the sewing presser plate 7. The bottom surface of the sewing presser plate 7 has a toothed structure. Compared to ordinary smooth presser plates which are prone to slipping, the toothed structure can grip the webbing, ensuring it will not shift even during high-speed sewing.

[0034] The working process of this utility model automatic sewing and bartacking machine for webbing bulges is as follows:

[0035] The webbing 10 to be sewn is placed in a folded form on the sewing station 51. Two sets of telescopic bulging devices 8 are activated, with their telescopic cylinders 81 pushing the bulging telescopic blocks 82 horizontally towards the sewing station 51, inserting them between the upper and lower layers of webbing, causing the upper layer of webbing to bulge. Because the front end of the bulging telescopic block 82 has a beveled structure, it can quickly insert between the upper and lower layers of webbing when extended. After the bulging step is completed, the pressing device 6 starts working, its drive mechanism driving the sewing pressure plate 7 to press down, pressing the webbing 10 tightly. The moving device 4 moves the sewing positioning plate 5 and the sewing pressure plate 7 in the XY direction, sending the webbing 10 below the bar-tapping sewing machine head 2.

[0036] The bar-stitch sewing machine head 2 starts, and the needle performs sewing operations along the seam groove 71. Simultaneously, the moving device 4 moves the webbing 10 along a preset trajectory to complete the bar-stitch. After completing one sewing operation, the moving device 4 transfers the webbing 10 to the positioning clamping device 9. The positioning clamping device 9 starts, and its transmission cylinder 91 drives the positioning clamping block 92 to press down, using its toothed structure at the bottom to clamp and fix the webbing 10. The pressing device 6 drives the sewing pressure plate 7 to rise, releasing the pressure on the webbing 10. Subsequently, the moving device 4 drives the sewing positioning plate 5 and the sewing pressure plate 7 back to their initial positions, preparing for the next bar-stitching, clamping, and sewing process. The raised telescopic block 82 is inserted again at a new position between the upper and lower webbing, causing the upper webbing to bulge. At the same time, the sewing pressure plate 7 presses down again at a new position to clamp the webbing 10. Then the positioning clamping device 9 is released, and the moving device 4 sends the webbing to the sewing machine head 2 for the sewing and bartending process.
