Description

Technical Field

[0001] The present invention relates to the technical field of garment processing, and particularly relates to an automatic hemming mechanism for fabrics, which is particularly suitable for the automatic improvement of hemming the opening edge and fabric pushing during the production of garment pockets. Background Art

[0002] In the process of garment manufacturing, the bag opening and hemming of pockets are key steps affecting the quality of finished products and production efficiency. In traditional processes, after the fabric is bagged, the edge of the bag opening needs to be hemmed to prevent the fabric from fraying and ensure the flatness after sewing. Currently, the following technical solutions are commonly used in the industry: 1. Manual operation: Workers fold the edge of the bag opening by hand and press and iron it into shape, and then sew it. This method relies on manual experience, has low efficiency and poor consistency, and is difficult to meet the needs of large-scale production; 2. Semi-automatic equipment: Some enterprises use hemming machines for auxiliary operations, such as hemming the fabric through mechanical pressing plates or rollers. However, the existing equipment has the following defects: 1. Insufficient adaptability: The equipment needs to align with the bag opening of the fabric to perform the hemming step. However, during the process of manually placing the fabric, misalignment is inevitable.

[0003] 2. Precision problem: The control of the hemming width is inaccurate, and deviations are likely to occur, affecting the subsequent sewing process. Summary of the Invention

The ends of the screws 36 will pass through the inner side of the gantry 32 movably and then be fixedly connected to the second helical gears 37. The sliding sleeve support plates 38 are sleeved on the screws 36, and both sliding sleeve support plates 38 are fixedly connected to the motor base 411. Two horizontally arranged second slide rails 311 are fixedly installed in the middle of the lower end surface of the bottom plate 39. A plurality of slidable second sliding sleeves 312 are sleeved on the second slide rails 311, and the plurality of second sliding sleeves 312 are fixedly connected to the motor base 411.

[0024] As Figure 3 shown, by driving the motor 33 to drive the first helical gear 34 and the second helical gear 37 to engage and rotate, the second helical gear 37 will drive the screw 36 to rotate. The screw 36 will engage with the sliding sleeve support plate 38. Thus, the hemming assembly 4 will realize left - right adjustment through the directional synchronous displacement of the sliding sleeve support plate 38 on the screw 36, and cooperate with the directional sliding of a plurality of second sliding sleeves 312 fixed to the upper end of the hemming assembly 4 on the second slide rail 311, reduce the force on the sliding sleeve support plate 38, and ensure the stability of the device.

[0025] The hemming assembly 4 includes a driving mechanism 41, a hemming plate group 42, and a sliding base 43. There are two sets of front - rear symmetric sliding bases 43 arranged on the front side of the driving mechanism 41. A hemming plate group 42 is arranged on the side where the two sliding bases 43 are close to each other. The hemming plate group 42 and the sliding base 43 are both fixedly installed on the driving mechanism 41.

[0026] The driving mechanism 41 includes a motor base 411, a servo motor 412, a driving screw 413, a fixed base 414, a third sliding sleeve 415, a third slide rail 416, a connecting plate 417, a sleeve plate 418 and a movable screw sleeve 419. The motor base 411 is a right-angled folding plate. The servo motor 412 is fixedly installed at the rear end of the motor base 411. The front end of the output shaft of the servo motor 412 is fixedly installed with the driving screw 413. Fixed bases 414 are fixedly installed at the bottoms of the left and right sides of the motor base 411. A third sliding sleeve 415 is fixedly installed at the bottom of the fixed base 414. The movable screw sleeve 419 is rotationally limited in the middle of the sleeve plate 418. The movable screw sleeve 419 meshes with the driving screw 413. Two connecting plates 417 are arranged below the sleeve plate 418. The front connecting plate 417 is fixedly connected to the sleeve plate 418. Two symmetrically arranged third slide rails 416 are fixedly installed above the two connecting plates 417. The third slide rails 416 are correspondingly arranged to slide with the third sliding sleeve 415.

[0027] As Figure 4 and Figure 5 shown, when the driving screw 413 at the output shaft end of the driving servo motor 412 is driven, the driving screw 413 will mesh with the movable screw sleeve 419. At this time, the movable screw sleeve 419 is limited by the third slide rail 416 connected to the bottom on the third sliding sleeve 415, so that the front folding edge plate group 42 will slide directionally on the driving screw 413 to meet the folding edge work of bag mouths with different sizes and widths, increasing the practicability of the device.

[0028] The folding edge plate group 42 includes an adjusting cylinder 421, a support plate 422, a fourth sliding sleeve 423, an extension plate 424, a guide plate 425 and a folding plate 426. The extension plate 424 is fixedly installed at the side end of the support plate 422. The two symmetrically arranged extension plates 424 on the left and right are fixedly connected to each other horizontally through the connecting plate 417. The folding plate 426 is fixedly installed at the bottom of the connecting plate 417. Guide plates 425 are arranged on the left and right sides of the folding plate 426. The guide plates 425 are used for the collision protection of the folding plate 426 to prevent the offset and damage caused by collision during the folding edge process of the folding plate 426. The fourth sliding sleeve 423 is fixedly installed on the side of the support plate 422 close to the sliding base 43. The fourth sliding sleeve 423 is correspondingly arranged to slide with the fourth slide rail 433, facilitating the sliding during the loading and unloading process of the folding edge plate group 42, helping to adjust the position of the folding plate 426, and assisting in disassembly and maintenance. The upper ends of the two rear support plates 422 are fixedly connected to the output shafts of the adjusting cylinder 421. The adjusting cylinder 421 is fixedly installed on both sides of the top of the motor base 411.

[0029] The sliding base 43 includes a synchronous cylinder 431, a fixing plate 432, and a fourth slide rail 433. Four synchronous cylinders 431 are installed below the top of the motor base 411. The fourth slide rail 433 is fixedly installed on the end face of the fixing plate 432 on the side close to the folding plate group 42. The fourth slide rail 433 is correspondingly arranged with the fourth sliding sleeve 423. Above the fixing plate 432, there is a synchronous cylinder 431. The synchronous cylinder 431 is fixedly installed below the top of the motor base 411. And on the side where the fixing plates 432 are close to each other, there are notches, so that the fixing plate 432 is in a C shape and can be loaded on the connecting plate 417. The output shaft of the synchronous cylinder 431 is not connected to the fixing plate 432, and the output shaft of the synchronous cylinder 431 applies corresponding pressure and limit to the fixing plate 432, so as to ensure that the folding plate group 42 will not tilt during the folding process.

[0030] As Figure 6 shown, by corresponding the fourth sliding sleeve 423 with the fourth slide rail 433 for sliding, it is convenient for the folding plate group 42 to slide during the loading and unloading process, helps to adjust the position of the folding plate 426, and assists in disassembly and maintenance. The output shaft of the synchronous cylinder 431 applies corresponding pressure and limit to the fixing plate 432, so as to ensure that the folding plate group 42 will not tilt during the folding process, thus protecting the use of the device and increasing the service life.

[0031] Specific implementation process: Before using this device, it is necessary to slide through the fourth sliding sleeve 423 and the fourth slide rail 433, which is convenient for the sliding of the folding plate group 42 during installation, helps to adjust the position of the folding plate 426 in the vertical direction, and is also convenient for disassembling and replacing the folding plate 426. And the output shaft of the synchronous cylinder 431 applies corresponding pressure and limit to the fixing plate 432, so as to ensure that the folding plate group 42 will not tilt during operation, protect the use of the device, and increase the service life; First of all, it is necessary to place the fabric on the table to be processed, preset the adjustment parameters of the limiting device according to the style of the bag mouth to be cut and sewn, then fix the fabric in position, cut the bag mouth of the fabric through the laser cutting device, and then move the fabric carried by the limiting device to directly below the folding mechanism of this device; Next, drive the driving screw 413 at the output shaft end of the servo motor 412. The driving screw 413 will engage with the movable nut 419. At this time, the movable nut 419 is restricted by the third slide rail 416 connected to the bottom and is limited on the third sliding sleeve 415, so that the front folding plate group 42 will slide directionally on the driving screw 413 to meet the folding work of bag mouths with different sizes and widths, increasing the practicability of the device; Then, the driving motor 33 drives the first helical gear 34 to mesh and rotate with the second helical gear 37. The second helical gear 37 drives the screw 36 to rotate. The screw 36 meshes with the sliding sleeve support plate 38. The hemming assembly 4 realizes left and right adjustment through the directional synchronous displacement of the sliding sleeve support plate 38 on the screw 36, and cooperates with the multiple second sliding sleeves 312 fixed at the upper end of the hemming assembly 4 to slide directionally on the second slide rail 311, reducing the stress on the sliding sleeve support plate 38 and ensuring the stability of the device; In this way, it is ensured that after the adjustment mechanism 3 slides and adjusts to the corresponding position, it can be aligned with the fabric manually placed on the bottom plate of the limiting device, adapt to the width and length of the bag mouth, and ensure smooth and more accurate hemming.

[0032] Finally, the bottom output shaft of the lifting cylinder 21 presses down the bottom plate 39. The first sliding sleeve 23 on the back plate 31 slides directionally with the first slide rail 22, so as to ensure the accuracy of the sliding of the folding plate 426 on the bottom device driven by the lifting cylinder 21, and perform hemming and pushing of the fabric and shearing waste limited and clamped on the bottom plate of the limiting device, reducing the deviation and preventing it from affecting the subsequent sewing process.

[0033] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantive changes to the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
