Description

Technical Field

[0001] This invention relates to the field of garment processing technology, specifically to an automatic fabric folding mechanism, which is particularly suitable for the automation improvement of folding the edges of openings and pushing fabric during the production of garment pockets. Background Technology

[0002] In garment manufacturing, the opening and hemming of pockets are crucial steps affecting finished product quality and production efficiency. Traditionally, after opening the fabric, the pocket edges need to be hemmed to prevent fabric fraying and ensure a smooth finish. Currently, the industry commonly uses the following technical solutions: 1. Manual operation: Workers manually fold the pocket edges and press them to shape before sewing. This method relies on manual experience, is inefficient and inconsistent, and cannot meet the needs of large-scale production; 2. Semi-automatic equipment: Some companies use hemming machines to assist in the operation, such as using mechanical pressure plates or rollers to hem the fabric. However, existing equipment has the following drawbacks:

[0003] 1. Insufficient adaptability: The equipment needs to be aligned with the opening of the fabric before it can be used for the folding process. However, misalignment is inevitable when the fabric is placed manually.

[0004] 2. Precision issues: Inaccurate control of the folded edge width can easily lead to deviations, affecting subsequent sewing processes. Summary of the Invention

The gantry frame is fixedly installed in the middle of the upper end face of the base plate. The motor is fixedly installed at the upper end of the gantry frame. The lower output shaft of the motor extends movably into the gantry frame, and a helical gear one is fixedly installed on the output shaft of the motor. Helical gear two meshing helical gears are provided on the left and right sides of the helical gear one. A screw is movably installed on one side of the two screw seats near the gantry frame. The end of the screw moves through the inside of the gantry frame and is fixedly connected to the helical gear two. The sliding sleeve support plate is sleeved on the screw, and both sliding sleeve support plates are fixedly connected to the motor base.

[0010] In a preferred embodiment: two transversely arranged slide rails are fixedly installed at the center of the lower end face of the base plate, and multiple slidable sleeves are fitted on the slide rails, with the multiple sleeves being fixedly connected to the motor base.

[0011] In a preferred embodiment: the driving mechanism includes a motor base, a servo motor, a drive screw, a fixed base, a sliding sleeve three, a slide rail three, a connecting plate, a sleeve plate, and a movable screw sleeve. The motor base is a right-angled folded plate. The servo motor is fixedly installed at the rear end of the motor base. The drive screw is fixedly installed at the front end of the output shaft of the servo motor. Fixed bases are fixedly installed on the bottom of both sides of the motor base. Sliding sleeve three is fixedly installed at the bottom of the fixed base. A movable screw sleeve is rotatably limited in the middle of the sleeve plate. The movable screw sleeve meshes with the drive screw. Two connecting plates are provided below the sleeve plate. The front connecting plate is fixedly connected to the sleeve plate. Two left-right symmetrical slide rails three are fixedly installed above the two connecting plates. The slide rails three and the sliding sleeve three are correspondingly slidable.

[0012] In a preferred embodiment: the folding plate assembly includes an adjusting cylinder, a support plate, a sliding sleeve, an extension plate, a guide plate, and a folding plate. An extension plate is fixedly installed on the side end of the support plate. Two symmetrical extension plates are fixedly connected left and right by a connecting plate.

The synchronizing cylinders are arranged above the fixed plate and are fixedly installed below the top of the motor base. The fixed plates are provided with notches on their adjacent sides, so that the fixed plates are C-shaped. The output shaft of the synchronizing cylinder is not connected to the fixed plate, and the output shaft of the synchronizing cylinder applies pressure to the fixed plate to limit its movement.

[0014] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0015] When this invention is used, the drive screw at the output shaft end of the servo motor will engage with the movable screw sleeve. At this time, the movable screw sleeve is restricted by the upper limit of the slide rail connected to the bottom, so that the front folding plate assembly will slide in a direction on the drive screw to meet the folding work of bag openings of different sizes and widths, increasing the practicality of the device.

[0016] In use, the invention drives a motor to rotate helical gear one and helical gear two, which in turn rotates a screw. The screw engages with a sliding sleeve support plate, allowing the folding assembly to adjust left and right through the directional synchronous displacement of the sliding sleeve support plate on the screw. This, combined with the directional sliding of multiple sliding sleeves two fixed to the upper end of the folding assembly on the slide rail two, reduces the stress on the sliding sleeve support plate, ensuring the stability of the device. This allows for adjustment of the fabric bag opening, even if manually placed inaccurately, ensuring smooth folding. The bottom output shaft of the lifting cylinder presses down on the base plate, causing the sliding sleeve one on the back plate to slide directionally with the slide rail one. This ensures the precise sliding of the folding plate on the bottom device driven by the lifting cylinder, folding and pushing the fabric and shearing waste material limited and clamped on the base plate of the limiting device.

For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0034] Please see Figures 1-6 In this embodiment, an automatic fabric folding mechanism is provided, including a support base 1, a lifting component 2, an adjusting mechanism 3, and a folding component 4. The lifting component 2 is fixedly installed at the front end of the support base 1, the adjusting mechanism 3 is fixedly installed at the front end of the lifting component 2, and the folding component 4 is fixedly installed at the lower end of the adjusting mechanism 3.

[0035] The support base 1 includes a support base 11, a fixed rod 12, a rotating seat 13, and a cylinder seat 14. The fixed rod 12 is fixedly installed at the front end of the support base 11. The rotating seat 13 is sleeved on the fixed rod 12. The rotating seat 13 is T-shaped and rotates around the fixed rod 12. The folding assembly 4 faces forward, which helps to replace folds of different thicknesses and provides convenience. It can provide a basis for the opening, closing, disassembly, and maintenance of the whole device. The cylinder seat 14 is fixedly installed at the upper end of the rotating seat 13. The cylinder seat 14 is used for the fixed installation of the lifting cylinder 21.

[0036] The lifting assembly 2 includes a lifting cylinder 21, a slide rail 22, and a sliding sleeve 23. The lifting cylinder 21 is fixedly mounted on the cylinder seat 14. The bottom output shaft of the lifting cylinder 21 is fixedly connected to the base plate 39. Two left-right symmetrical slide rails 22 are mounted on the front end face of the rotating seat 13. Multiple sliding sleeves 23 are provided on the slide rails 22. The sliding sleeves 23 are fixedly connected to the back plate 31 to ensure that the device can reciprocate along the orientation position of the slide rails 22 during the folding process.

[0037] like Figure 2 As shown, the bottom output shaft of the lifting cylinder 21 presses down the base plate 39, and the sliding sleeve 23 on the back plate 31 slides in a direction with the slide rail 22, thereby ensuring the accuracy of the sliding of the folding plate 426 on the bottom device driven by the lifting cylinder 21, and folding and pushing the fabric and shearing waste material that are limited and clamped on the base plate of the limiting device.

[0038] The adjustment mechanism 3 includes a back plate 31, a gantry frame 32, a motor 33, a first helical gear 34, a screw seat 35, a screw 36, a second helical gear 37, a sliding sleeve support plate 38, a base plate 39, a reinforcing rib 310, a second slide rail 311, and a second sliding sleeve 312. The bottom of the back plate 31 is bolted to the base plate 39. Reinforcing ribs 310 are fixedly installed between the upper end of the base plate 39 and both sides of the back plate 31. A clearance opening is provided in the middle of the reinforcing rib 310, and a screw seat 35 is provided in the clearance opening. The screw seat 35 is fixedly installed on the base plate 39. The gantry frame 32 is fixedly installed in the middle of the upper end face of the base plate 39. The motor 33 is fixedly installed at the upper end of the gantry frame 32. The lower end of the motor 33 outputs a shaft. The motor 33 extends into the gantry frame 32, and a helical gear 34 is fixedly installed on the output shaft of the motor 33. Helical gears 37 meshing with each other are provided on the left and right sides of the helical gear 34. Two screw seats 35 are movably installed on one side of the gantry frame 32 with screws 36. The end of the screw 36 moves through the inside of the gantry frame 32 and is fixedly connected to the helical gears 37. Sliding sleeve support plates 38 are sleeved on the screws 36, and both sliding sleeve support plates 38 are fixedly connected to the motor seat 411. Two horizontally arranged sliding rails 311 are fixedly installed in the middle of the lower end face of the base plate 39. Multiple sliding sleeves 312 are sleeved on the sliding rails 311 and are fixedly connected to the motor seat 411.

[0039] like Figure 3 As shown, the drive motor 33 drives the helical gear 34 and the helical gear 37 to mesh and rotate. The helical gear 37 drives the screw 36 to rotate. The screw 36 meshes with the sliding sleeve support plate 38. Thus, the folding assembly 4 can be adjusted left and right by the directional synchronous displacement of the sliding sleeve support plate 38 on the screw 36. In addition, the multiple sliding sleeves 312 fixed at the upper end of the folding assembly 4 slide directionally on the slide rail 311, reducing the stress on the sliding sleeve support plate 38 and ensuring the stability of the device.

[0040] The folding assembly 4 includes a drive mechanism 41, a folding plate assembly 42, and a sliding base 43. Two sets of symmetrical sliding bases 43 are provided on the front side of the drive mechanism 41. The folding plate assembly 42 is provided on one side of the two sliding bases 43 close to each other. The folding plate assembly 42 and the sliding base 43 are both fixedly installed on the drive mechanism 41.

[0041] The drive mechanism 41 includes a motor base 411, a servo motor 412, a drive screw 413, a fixed base 414, a sliding sleeve 415, a 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 folded plate. The servo motor 412 is fixedly mounted at the rear end of the motor base 411. The drive screw 413 is fixedly mounted at the front end of the output shaft of the servo motor 412. Fixed bases 414 are fixedly mounted on the bottom of both the left and right sides of the motor base 411. 14. A sliding sleeve 415 is fixedly installed at the bottom of the fixed base 414. A movable screw sleeve 419 is provided in the middle of the sleeve plate 418 to limit rotation. The movable screw sleeve 419 meshes with the drive screw 413. Two connecting plates 417 are provided below the sleeve plate 418. The front connecting plate 417 is fixedly connected to the sleeve plate 418. Two left-right symmetrical sliding rails 416 are fixedly installed above the two connecting plates 417. The sliding rails 416 and the sliding sleeve 415 are correspondingly set to slide.

[0042] like Figure 4 and Figure 5 As shown, the drive screw 413 at the output shaft end of the drive servo motor 412 will engage with the movable screw sleeve 419. At this time, the movable screw sleeve 419 is restricted by the slide rail 3 416 connected to the bottom at the upper limit of the slide sleeve 3 415, so that the front folding plate assembly 42 will slide in a direction on the drive screw 413 to meet the folding work of bag openings of different sizes and widths, and increase the practicality of the device.

[0043] The folding plate assembly 42 includes an adjusting cylinder 421, a support plate 422, a sliding sleeve 423, an extension plate 424, a guide plate 425, and a folding plate 426. The extension plate 424 is fixedly installed on the side end of the support plate 422. Two symmetrical extension plates 424 are fixedly connected left and right by a connecting plate 417. The folding plate 426 is fixedly installed on the bottom of the connecting plate 417. Guide plates 425 are provided on the left and right sides of the folding plate 426. The guide plates 425 are used for collision protection of the folding plate 426 to prevent collisions. 26. In case of displacement and damage caused by collision during the folding process, the support plate 422 is fixedly installed with the sliding sleeve 423 on the side of the sliding base 43. The sliding sleeve 423 and the sliding rail 433 are correspondingly set to slide, which facilitates the sliding of the folding plate assembly 42 during the loading and unloading process, helps to adjust the position of the folding plate 426, and assists in disassembly and maintenance. The upper ends of the two support plates 422 on the rear side are fixedly connected to the output shaft of the adjusting cylinder 421. The adjusting cylinder 421 is fixedly installed on the top two sides of the motor base 411.

[0044] The sliding base 43 includes a synchronous cylinder 431, a fixed plate 432, and a slide rail 433. Four synchronous cylinders 431 are installed below the top of the motor base 411. The slide rail 433 is fixedly installed on one end face of the fixed plate 432 near the edge plate assembly 42. The slide rail 433 is correspondingly arranged with the sliding sleeve 423. The synchronous cylinder 431 is arranged above the fixed plate 432. The synchronous cylinder 431 is fixedly installed below the top of the motor base 411. The fixed plate 432 has a notch on one side close to each other, so that the fixed plate 432 is C-shaped and can be mounted on the connecting plate 417. The output shaft of the synchronous cylinder 431 is not connected to the fixed plate 432, and the output shaft of the synchronous cylinder 431 applies pressure to the fixed plate 432 to limit it, thereby ensuring that the edge plate assembly 42 will not tilt during the edge folding process.

[0045] like Figure 6 As shown, the sliding sleeve 423 and the sliding rail 433 are correspondingly set to slide, which facilitates the sliding of the folding plate assembly 42 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 pressure to the fixed plate 432 to limit it, thereby ensuring that the folding plate assembly 42 will not tilt during the folding process, thus protecting the device and increasing its service life.

[0046] Specific implementation process:

[0047] Before using this device, it is necessary to slide the sliding sleeve 423 and the sliding rail 433 to facilitate the sliding of the folding plate assembly 42 during installation, help adjust the vertical position of the folding plate 426, and facilitate the disassembly and replacement of the folding plate 426. The output shaft of the synchronous cylinder 431 applies pressure to the fixed plate 432 to limit its movement, thereby ensuring that the folding plate assembly 42 will not tilt during operation, protecting the device and increasing its service life.

[0048] First, the fabric needs to be placed on the processing table. The bag opening style to be cut and sewn is required. The adjustment parameters of the limiting device are preset. Then, the limiting device is fixed. The bag opening of the fabric is cut by the laser cutting device. Then, the fabric carried by the limiting device is moved to the folding mechanism of this device.

[0049] Next, the drive screw 413 at the output shaft end of the drive servo motor 412 will engage with the movable screw sleeve 419. At this time, the movable screw sleeve 419 is restricted by the slide rail 3 416 connected to the bottom at the upper limit of the slide sleeve 3 415, so that the front folding plate assembly 42 will slide in a direction on the drive screw 413 to meet the folding work of bag openings of different sizes and widths, and increase the practicality of the device.

[0050] Then, the drive motor 33 drives the helical gear 1 34 and the helical gear 2 37 to mesh and rotate. The helical gear 2 37 drives the screw 36 to rotate. The screw 36 meshes with the sliding sleeve support plate 38. The folding assembly 4 will achieve left and right adjustment through the directional synchronous displacement of the sliding sleeve support plate 38 on the screw 36. In addition, the multiple sliding sleeves 2 312 fixed at the upper end of the folding assembly 4 slide directionally on the slide rail 2 311 to reduce the stress on the sliding sleeve support plate 38 and ensure the stability of the device.

[0051] This ensures that after the adjustment mechanism 3 makes the corresponding sliding adjustment, it can be aligned with the fabric that is manually placed on the bottom plate of the limiting device to deal with the width and length of the bag opening, thus ensuring smooth and more accurate folding.

[0052] Finally, the bottom output shaft of the lifting cylinder 21 presses down the base plate 39, and the sliding sleeve 23 on the back plate 31 slides in a direction with the slide rail 22, thereby ensuring the accuracy of the sliding of the folding plate 426 on the bottom device driven by the lifting cylinder 21. This allows for the folding and pushing of the fabric and cutting waste that are limited and clamped on the base plate of the limiting device, reducing deviation and preventing it from affecting subsequent sewing processes.

[0053] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
