[0001] This utility model belongs to the field of sewing technology, specifically relating to an automatic collar sewing and trimming machine. Background Technology

[0002] Currently, collar sewing is a crucial and complex process in the garment manufacturing industry. Traditional collar sewing techniques mainly rely on manual operation and involve multiple steps, including fabric folding, sewing, and cutting. Specifically, the manual production process is not only time-consuming but also requires a high level of skill from the operators.

[0003] Due to the limited speed of manual operation and the fact that each step requires a significant amount of time for precise execution, overall production efficiency is difficult to improve, failing to meet the demands of modern garment manufacturing for large-scale, high-efficiency production. Furthermore, the differences in skill levels, operating habits, and work conditions among different operators result in inconsistent quality for each collar product, making it difficult to guarantee standardization and consistency, which in turn affects the overall quality and brand image of the garments.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] like Figure 1-2 As shown, this utility model provides an automatic collar sewing and trimming machine, including a frame 1. A rotating disk 2 is rotatably connected to the top surface of the frame 1. A rotation drive component 21 for driving the rotating disk 2 to rotate is provided in the middle of the rotating disk 2. The rotation drive component 21 is preferably a servo motor. The frame 1 is provided with multiple working positions 11, including at least a feeding position 111, a sewing position 112, a cutting position 113, and a discharging position 114. The rotating disk 2 is provided with clamping components 7 corresponding to each of the working positions 11 and used to clamp and fix the collar. The frame 1 is also provided with a feeding mechanism 3, a sewing mechanism 4, a cutting mechanism 5, and a discharging mechanism 6 respectively corresponding to the feeding position 111, the sewing position 112, the cutting position 113, and the discharging position 114. In use, the worker stacks the multiple layers of fabric needed for the collar on top of each other in the feeding position 111, and clamps and fixes them using the clamping assembly 7 in the feeding position 111. Then, the rotary drive 21 drives the rotary disk 2 to rotate 90°, so that the collar fabric is conveyed to the sewing position 112 along with the clamping assembly 7, and the collar is sewn using the sewing mechanism 4. Next, the rotary disk 2 rotates 90° again, so that the collar is conveyed to the cutting position 113 along with the clamping assembly 7, and the cutting machine is used for the cutting process. The collar is trimmed by the clamping assembly 7; finally, the collar is rotated 90° again by the clamping assembly 7 and sent to the unloading position 114. The unloading mechanism 6 is used to unload the sewn and cut collar. Through the design of multiple workstations 11 and multiple mechanisms, the worker only needs to load the material at the loading position 111, while the other workstations 11 use the mechanisms to automatically sew, cut and unload in batches, which greatly improves the production efficiency of collars and the high consistency of products, and can also effectively reduce the workload of workers and labor costs. Meanwhile, the clamping components 7 on the rotating disk 2 are provided in multiple ways and are respectively set one-to-one with each of the working positions 11. Therefore, when feeding materials, other working positions 11 can also perform synchronous sewing, cutting and unloading operations, thereby further improving the degree of automation and the production efficiency of collars.

[0035] Specifically, such as Figure 3-4As shown, the feeding mechanism 6 includes a feeding frame 61, a first swing arm 62, a second swing arm 63, a feeding drive component 64, and a feeding claw 65. The two first swing arms 62 are arranged in pairs, and one end of each is rotatably connected to the feeding frame 61. The second swing arms 63 are also arranged in pairs and rotatably connected between the other ends of the two first swing arms 62. The second swing arm 63 is provided with a swing end 631 and a feeding end 632. The rotatable connection point A between the second swing arm 63 and the first swing arm 62 is located at the swing end 631. Between the first swing arm 62 and the unloading end 632; between the two second swing arms 63, there is a drive rod 633 located at the swing end 631, a unloading rod 634 located at the unloading end 632, and a rotating shaft 635 connected to the first swing arm 62; the unloading drive 64 is preferably a cylinder and one end of it is rotatably connected to the unloading frame 61, and the other end is rotatably connected to the drive rod 633 in the swing end 631; the material claw 65 is disposed on the unloading rod 634 of the unloading end 632. During unloading, the unloading drive 64 extends, pushing the drive rod 633 to swing downwards around the rotating connection point A. Under the force of the lever, the unloading rod 634 drives the material claw 65 to rise and clamp the collar located in the unloading position 114 (or initially, the material claw 65 corresponds exactly to the collar position, and when the collar is conveyed to the unloading position 114, the collar is exactly on the material claw 65); then, the material claw 65 clamps the collar, the unloading drive 64 retracts, causing the drive rod 633 to swing downwards around the rotating connection point A. When contact A is raised, the unloading rod 634 drives the material claw 65 and the collar to be pulled out and moved downwards simultaneously. At this time, the unloading drive 64 can be retracted as needed, thereby driving the first swing arm 62 to swing outwards, so that the material claw 65 and the collar are set downwards. After the material claw 65 is released, the collar falls into the storage bin located in the unloading position 114, completing the unloading. Finally, under the pushing action of the unloading drive 64, the first swing arm 62, the second swing arm 63 and the material claw 65 are reset again to unload the next collar. Furthermore, in order to improve the clamping stability of the collar by the material claws 65, both ends of the material feed rod 634 extend outwards towards the two second swing arms 63, and the material claws 65 are respectively provided at both ends of the material feed rod 634; during operation, the two material claws 65 open and close synchronously to achieve multi-point clamping and fixing of the collar. Preferably, the feed claw 65 is a finger cylinder; By setting up the feeding mechanism 6, the collar feeding is automated, further reducing labor costs. At the same time, the feeding mechanism 6 is not only simple in structure, low in cost, and long in service life, but also effectively realizes the swing of the first swing arm 62 and the second swing arm 63 by using the lever principle. It is labor-saving and has a large adjustment range, making it easy to adjust different feeding points to adapt to different storage positions.

[0036] Specifically, such as Figure 5-10 As shown, the clamping assembly 7 includes an opening and closing drive component 71, and an upper clamping unit 72 and a lower clamping unit 73 arranged correspondingly around the rotating disk 2. The lower clamping unit 73 is fixed to the bottom edge of the rotating disk 2. One end of the upper clamping unit 72 is rotatably connected to the top surface of the rotating disk 2, and the other end is close to or away from the lower clamping unit 73 to clamp the collar. The opening and closing drive component 71 is preferably a cylinder, with one end rotatably connected to the rotating disk 2 and the other end rotatably connected to the upper clamping unit 72. Thus, the opening and closing control of the upper clamping unit 72 and the lower clamping unit 73 is realized by the extension and retraction of the opening and closing drive component 71.

[0037] Furthermore, the upper clamping unit 72 includes an adjusting seat 721 connected to the opening and closing drive member 71, upper fixing blocks 722 respectively disposed on both sides of the adjusting seat 721, a lead screw 723 connected between the upper fixing blocks 722 and the adjusting seat 721, and an upper clamping member 724 slidably connected to the lead screw 723. The upper clamping member 724 is provided with a nut 725 threadedly connected to the lead screw 723. At this time, the two upper clamping members 724 are slidably connected to both sides of the adjusting seat 721. The two upper fixing blocks 722 are rotatably connected to the rotating disk 2, thereby realizing the rotatable connection between the upper clamping unit 72 and the rotating disk 2. Through the threaded engagement between the lead screw 723 and the nut 725 in the upper clamping member 724, the translation distance of the upper clamping member 724 can be adjusted synchronously when the lead screw 723 rotates to adapt to different sizes of collars, thereby improving the clamping and fastening force on the collar. Furthermore, such as Figure 7 As shown, in order to improve the convenience of adjusting the distance between the two upper clamping members 724, the adjusting seat 721 is also provided with an adjusting drive member 7211. The adjusting drive member 7211 is preferably a motor, and its output end is respectively connected to one end of the two lead screws 723 through gears 726. When the adjusting drive member 7211 drives the gears 726 to rotate, since the gears 726 corresponding to the two lead screws 723 are respectively arranged on both sides of the adjusting drive member 7211, the direction of rotation of the two lead screws 723 is realized, thereby realizing the control of the two upper clamping members 724 to move closer or further apart. Preferably, such as Figure 8-9As shown, the lower clamping unit 73 includes two lower fixing blocks 731 fixedly mounted on the rotating disk 2, a guide post 732 connected between the two lower fixing blocks 731, and two lower clamping members 733 slidably connected to the guide post 732. The two lower clamping members 733 correspond one-to-one with the two upper clamping members 724. The upper clamping member 724 is provided with a downwardly extending synchronization plate 7241, and the lower clamping member 733 is provided with a synchronization groove 7331, with the synchronization plate 7241 extending into the synchronization groove 7331. When the distance between the two upper clamping members 724 is adjusted by the adjusting drive member 7211, the upper clamping member 724 and the lower clamping member 733 move synchronously under the pushing action of the synchronization plate 7241. Meanwhile, in order to accommodate the opening and closing rotation of the upper clamping unit 72, the synchronizing plate 7241 is designed with an arc shape, so that the synchronizing plate 7241 can be installed in the synchronizing groove 7331 when the upper clamping unit 72 is in the open or closed state, thereby realizing that the upper clamping member 724 and the lower clamping member 733 can be adjusted and moved synchronously in the open and closed states respectively.

[0038] Specifically, such as Figure 10 As shown, the upper clamping member 724 and the lower clamping member 733 have the same structure, both including a clamping base 74 and a clamping plate 75. The clamping plate 75 is mounted on the clamping base 74 for clamping the collar. In practical applications, to adapt to different collar shapes and other garment shapes, different clamping plates 75 may need to be replaced. To improve the ease of replacement of the clamping plate 75, the clamping base 74 is provided with a mounting groove 741, and the clamping plate 75 is provided with a mounting post 751 corresponding to the mounting groove 741. The clamping base 74 is provided with a locking member 742, and the locking member 742 is provided with a locking shaft 743 extending into the mounting groove 741. The column 751 is provided with a locking hole 752 that matches the locking shaft 743. The locking element 742 is preferably a cylinder, and the locking shaft 743 is the telescopic shaft of the cylinder. When the clamping plate 75 needs to be replaced, simply drive the locking shaft 743 to retract and disengage from the locking hole 752 to disassemble the clamping plate 75 from the clamping seat 74. During installation, simply insert another clamping plate 75 into the mounting groove 741 through the mounting column 751, and then drive the locking shaft 743 to extend into the locking hole 752 to lock the clamping plate 75. The structure is simple and the replacement is convenient and quick, effectively improving the clamping versatility of the clamping assembly 7.

[0039] Specifically, such as Figure 11As shown, the feeding mechanism 3 includes a support block 31, a feeding frame 32, and a feeding drive component 33. The feeding frame 32 includes a support plate 321 and two support legs 322 disposed at the bottom of the support plate 321. The two support blocks 31 are fixedly disposed on the frame 1, and the free ends of the two support legs 322 are rotatably connected to the support blocks 31 respectively, thereby realizing the rotatable connection between the feeding frame 32 and the frame 1. The feeding drive component 33 is rotatably connected to the frame 1 at one end and rotatably connected to the bottom of the support plate 321 at the other end. The feeding drive component 33 is preferably a cylinder. When the feeding drive 33 extends, the feeding rack 32 rises, so that the support plate 321 is parallel to the bottom of the clamping plate 75 of the lower clamping member 733 to support the clamping plate 75. At the same time, the area of ​​the support plate 321 is larger than the area of ​​the clamping plate 75. Therefore, when workers lay and stack collar fabric, the flatness of the collar fabric can be effectively improved, which greatly improves the finished quality of the collar and the convenience of feeding for workers. After feeding is completed, the feeding drive 33 retracts and drives the feeding rack 32 to move downward to avoid interfering with the rotation of the rotating disk 2.

[0040] Specifically, such as Figure 12 As shown, the sewing mechanism 4 includes a first XY translation module 41 and a sewing machine 42 slidably connected to the first XY translation module 41. When the rotary disk 2 moves the stacked collar from the loading position 111 to the sewing position 112, the first XY translation module 41 drives the sewing machine 42 to move around the collar for sewing. Through the mechanized sewing of the sewing mechanism 4, the efficiency of collar sewing and the consistency of the finished collar are effectively improved.

[0041] Specifically, such as Figure 13 As shown, the cutting mechanism 5 includes a second XY translation module 51, a cutting bracket 52 disposed on the second XY translation module 51, a cutting unit 53 rotatably connected to the cutting bracket 52, and a rotating component 54 that drives the cutting unit 53 to rotate. During operation, after the rotating disk 2 moves the collar from the sewing position 112 to the cutting position 113, the second XY translation module 51 drives the cutting bracket 52 and the cutting unit 53 to move and cut the collar. At the same time, the rotating component 54 drives the cutting unit 53 to rotate via a belt, thereby realizing bending and cutting according to the shape of the collar, effectively improving the cutting flexibility and accuracy. Furthermore, such as Figure 14-15As shown, the cutting unit 53 includes a support frame 531, a cutting drive component 532, an eccentric component 533, a connecting component 534, a moving blade 535, and a fixed blade 536. The support frame 531 is fixed to the cutting bracket 52, the cutting drive component 532 is fixed to the support frame 531, and the eccentric component 533 is rotatably connected to the support frame 531. The cutting drive component 532 drives the eccentric component 533 to eccentrically swing or rotate via a belt and rollers. One end of the connecting component 534 is connected to the eccentric end of the eccentric component 533, and the other end is connected to the moving blade 535 and extends downward through the cutting bracket 52. When the eccentric component 533 performs eccentric movement... The connecting member 534 and the moving blade 535 move up and down synchronously. At this time, the fixed blade 536, which is fixedly set at the bottom of the support frame 531, cooperates with the moving blade 535 to cut, thereby achieving effective cutting of the collar. In order to improve the cutting accuracy, the fixed blade 536 is also provided with a "V" shaped cut 537. During cutting, the cutting unit 53 moves to the collar, so that the collar fabric extends into the cut 537. At this time, the cutting drive member 532 is preferably a motor and rotates, thereby driving the moving blade 535 to reciprocate up and down relative to the fixed blade 536 to cut the fabric in the cut 537. The cutting operation is fast and effective, further improving the manufacturing efficiency of the collar. Preferably, such as Figure 16 As shown, since the cut waste fabric may interfere with the collar making process, the cutting bracket 52 is also equipped with a suction plate 55. The suction plate 55 is located below the cutting unit 53. The suction plate 55 is also equipped with suction holes 551 corresponding to the upper and lower parts of the cutting unit 53. The suction holes 551 are connected to suction tubes 552. After the cutting work begins, the suction tubes 552 start synchronously. The cut waste fabric will be quickly adsorbed into the suction holes 551 under the action of suction and its own gravity and then sucked away and recycled by the suction tubes 552. At the same time, since the suction plate 55 is fixedly connected to the cutting bracket 52, and the rotation axis of the cutting unit 53 is coaxial with the suction holes 551, the suction holes 551 always remain coaxial with the cutting unit 53, regardless of whether the cutting unit 53 moves horizontally or rotates, thereby improving the collection stability of waste fabric.

[0042] Specifically, such as Figure 1-2 As shown, the unloading rack 61 is also provided with a crossbeam 66 connected to the rotary drive component 21, and a control panel 67 is provided on the crossbeam 66; in this embodiment, the above-mentioned drive components can be directly or indirectly electrically connected to the control panel 67, thereby realizing the integrated function control of the equipment, making the operation more convenient and simple, and facilitating workers to quickly get started.

[0043] The innovation of this utility model lies in its full utilization of the mechanical cooperation between multiple workstations and mechanisms, which effectively improves the automation level, production efficiency, and quality consistency of the finished collars. Secondly, by setting a feeding mechanism at the feeding position, the collar feeding is automated, and by making full use of the lever swing principle, the position of the collar feeding point can be automatically adjusted to adapt to different collar feeding and storage positions. Furthermore, by setting a suction plate with suction holes below the cutting unit, and ensuring that the suction holes and the cutting unit are always coaxially aligned, the scrap fabric is collected quickly and accurately, effectively preventing scrap fabric from interfering with the collar making process.

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
