Description

Technical Field

[0001] The utility model relates to the field of sewing machines, in particular to a full-automatic material folding and sewing sleeve fork machine. Background Art

[0002] Currently, before the cuff fabric is sewn onto the garment, it must first be folded and heat-set separately, and then the heat-set cuff fabric is placed on a cuff sewing machine to be sewn together with the sleeve fabric.

[0003] The heat setting treatment of the cuff fabric will take a lot of time, which will extend the production time of the sleeve fabric to a certain extent. Therefore, it is necessary to design a cuff machine that can sew the cuff fabric and the sleeve fabric together immediately after folding the cuff fabric, thereby improving the production efficiency of the sleeve. Utility Model Content

[0004] The present application provides a fully automatic sleeve fork folding and sewing machine, which can realize automatic folding of sleeve forks and complete the sewing of sleeve fork fabric and sleeve fabric.

[0005] The fully automatic sleeve folding and sewing machine provided by this application adopts the following technical solutions:

[0006] A fully automatic sleeve folding and sewing machine comprises a frame, an X-axis movable platform and a Y-axis movable platform arranged on the frame, wherein a sewing head is arranged on the Y-axis movable platform, and is characterized in that:

[0007] It also includes a bottom plate, which is arranged on the X-axis moving platform and has a folding groove;

[0008] A material pressing mechanism is provided on the X-axis movable platform and is used to press a portion of the main body of the sleeve fork fabric placed on the base plate into the folding groove, so that the end of the sleeve fork fabric that is not pressed into the folding groove is raised to form a warped edge;

[0009] A folding mechanism, which is provided on the bottom plate and is used to push the warped edge of the sleeve fabric onto the pressing mechanism, so that the warped edge of the sleeve fabric is bent to form a folded edge;

[0010] A pressing mechanism, which is provided on the X-axis moving platform and is used to press the sleeve fabric and the cuff fabric placed on the hemmed cuff fabric;

[0011] The X-axis moving platform and the Y-axis moving platform drive the base plate and the sewing head to move so that the sewing head sews the cuff fabric and the sleeve fabric pressed by the pressing mechanism.

[0012] By adopting the above technical solution, the automatic hemming of the cuff can be achieved and the sewing of the cuff fabric and the sleeve fabric can be completed.

[0013] Preferably, the pressing mechanism includes a first mounting plate rotatably connected to the X-axis movable platform, a second driving portion provided on the X-axis movable platform and used to drive the first mounting plate to rotate, a sliding seat 1 connected to the first mounting plate and slidingly connected along the X-axis direction, a third driving portion provided on the first mounting plate and used to drive the sliding seat 1 to slide, and a metal pressing sheet 1 provided on the sliding seat 1, and the folding groove is located below the movement path of the metal pressing sheet 1 in the X-axis direction.

[0014] By adopting the above technical solution, after the staff places the cuff fabric on the base plate, the third driving unit drives the sliding seat 1 to slide, allowing the metal pressing plate 1 to move above the folding groove. Then, the second driving unit drives the first mounting plate to rotate. The rotation of the first mounting plate rotates the metal pressing plate 1, causing the metal pressing plate 1 to press the cuff fabric into the folding groove. At this time, the end of the cuff fabric that is not pressed into the folding groove will rise up to form a warped edge.

[0015] Preferably, a fifth cylinder is provided on the X-axis moving platform, and the fifth cylinder is located directly above the folding trough. The output shaft of the fifth cylinder is set toward the folding trough, and a Y-shaped pressing block is provided on the output shaft of the fifth cylinder. The folding trough is located on the movement path of the Y-shaped pressing block.

[0016] By adopting the above technical solution, after the metal pressing plate 1 presses a part of the sleeve fork fabric into the folding trough, the metal pressing plate 1 bends, so that the metal pressing plate 1 may not be able to fully press the sleeve fork fabric entering the folding trough. Therefore, a Y-shaped pressing block is provided. When the metal pressing plate 1 presses the sleeve fork fabric, the Y-shaped pressing block presses the metal pressing plate 1 located in the folding trough to ensure the pressing effect of the metal pressing plate 1 on the sleeve fork fabric, and prevent the fabric from shifting when the sleeve fork fabric is folded, affecting the folding quality. The output shaft of the fifth cylinder is extended, allowing the Y-shaped pressing block to descend and press the metal pressing plate 1, so that the two ends of the metal pressing plate 1 located in the folding trough can fully press the sleeve fork fabric onto the frame, and prevent the situation where a part of the sleeve fork fabric is not pressed. In this way, the sleeve fork fabric can be prevented from moving during the subsequent folding process, and the quality of the sleeve fork fabric folding can be ensured.

[0017] Preferably, the folding mechanism includes a push plate that is slidably connected to the base plate along the Y-axis direction to push the edge of the sleeve fork fabric, and a fourth driving part for driving the folding push plate to move, and the folding trough is located below the movement path of the folding plate in the Y-axis direction.

[0018] With this technical solution, after the cuff hem is formed, the fourth drive unit drives the hem pusher plate, causing it to push the cuff material not yet pressed into the folding trough onto the pressing mechanism, bending the warped edge of the cuff material to form a hem. Once the cuff hem is finalized, the fourth drive unit controls the hem pusher plate to reset. The third drive unit resets the sliding seat, allowing the metal pressing plate to be withdrawn from the hem-folded cuff material. The second drive unit then drives the first mounting plate to flip and reset, preparing for the next cuff hem.

[0019] Preferably, a guide plate is provided on the bottom plate, a guide space is provided between the guide plate and the bottom plate, the folding push plate is slidably connected in the guide space, and the fourth driving part is provided on the guide plate.

[0020] By adopting the above technical solution, the hemming push plate is prevented from bending and deforming when pushing the cuff fabric to fold the hem, thereby ensuring the hemming quality of the cuff fabric.

[0021] Preferably, the pressing mechanism includes a second mounting plate rotatably connected to the X-axis movable platform, a sixth driving portion provided on the X-axis movable platform and used to drive the second mounting plate to rotate, a sliding seat 2 connected to the second mounting plate and slidingly connected along the X-axis direction, a seventh driving portion provided on the second mounting plate and used to drive the sliding seat 2 to slide, and a metal pressing sheet 2 provided on the sliding seat, and the folding groove is located below the movement path of the metal pressing sheet 2 in the X-axis direction.

[0022] With this technical solution, after the cuff fabric is hemmed, the worker places the sleeve fabric on top of the hemmed cuff fabric. The seventh drive slide seat 2 then slides, allowing the metal pressing plate 2 to move above the folding trough. The sixth drive unit then flips the second mounting plate, causing the metal pressing plate 2 to flip and press the connection between the cuff fabric and the sleeve fabric. This prevents relative displacement of the sleeve and cuff fabrics during sewing, which could affect sewing quality.

[0023] Preferably, a connecting block and an eighth driving unit are further provided on the X-axis moving platform. The connecting block is rotatably connected to the X-axis moving platform. The eighth driving unit is used to drive the connecting block to rotate. A connecting rod is provided on one end of the connecting block. A pressing plate is provided on the end of the connecting rod. The pressing plate presses the sleeve fabric placed on the bottom plate.

[0024] By adopting the above technical solution, after the cuff fabric is folded, the eighth driving unit drives the connecting block to flip, so that the pressing plate presses the sleeve fabric around the folding groove to prevent the sleeve fabric from moving, thereby ensuring the sewing quality of the cuff fabric and the sleeve fabric during sewing.

[0025] Preferably, a limit block and a ninth driving part are further provided on the second mounting plate. The limit block is slidably connected to the second mounting plate. The limit block is always located on the movement path of the sliding seat 2. The ninth driving part is used to drive the limit block to slide.

[0026] By adopting the above technical solution, the ninth driving part drives the limit block to slide, so that the limit block moves to the appropriate position and limits the final movement position of the sliding seat 2, so that after the sliding seat 2 slides, the metal pressing sheet 2 can move more accurately above the folding groove.

[0027] Preferably, a material return mechanism is provided on the frame, and the material return mechanism is used to move the sewn cuff fork fabric and sleeve fabric out of the base plate. The material return mechanism includes a material return piece 1, a material return piece 2, a tenth driving unit, and an eleventh driving unit. The material return piece 1 and the material return piece 2 are both slidably connected to the frame. The tenth driving unit is used to control the sliding of the material return piece 1, and the eleventh driving unit is used to control the sliding of the material return piece 2. A channel is formed between the material return piece 2 and the material return piece 1, and the end of the sleeve fabric is located in the channel.

[0028] By adopting the above technical solution, the first stripper is initially away from the frame, while the second stripper is closer to the frame. When the operator places the sleeve fabric on the base plate, one end of the sleeve fabric is allowed to hang down into the channel. After the sleeve fork fabric and the sleeve fabric are sewn together, the tenth drive unit controls the first stripper to slide toward the frame, and the eleventh drive unit also controls the second stripper to move away from the frame. As the second stripper and the first stripper move, they pull the sleeve fabric away from the base plate, and finally hook it on the second stripper, completing the automatic stripping of the sleeve fabric.

[0029] Preferably, a base plate is provided on the frame, the bottom plate is located above the base plate, a plurality of through holes are opened on the base plate, and the plurality of through holes are directly opposite the folding trough. A cylinder twelve is also provided on the frame, and the cylinder twelve is located below the base plate. A fixed plate is provided on the output shaft of the cylinder twelve, and a plurality of ejectors are provided on the fixed plate, and the ends of the plurality of ejectors are respectively located in the plurality of through holes.

[0030] By adopting the above technical solution, due to the problem of the sewing process, the pressing mechanism will hinder the sewing path of the sewing head when sewing the sleeve fabric and the cuff fabric. Therefore, after the sewing head has sewn a portion of the sleeve fabric and the cuff fabric, the pressing assembly will move back and press the connection between the sleeve fabric and the cuff fabric again. At this time, the output shaft of the cylinder 12 extends, carrying the fixed plate and multiple thimbles upward, so that the heads of the multiple thimbles slightly expose the multiple through holes and contact the cuff fabric, so that a certain amount of friction is generated between the two. When the sleeve fabric and the cuff fabric are sewn, the cuff fabric is pulled to prevent the sleeve fabric from moving around, thereby assisting the pressing mechanism to ensure the sewing quality of the sleeve fabric and the cuff fabric.

[0031] The technical effects of this utility model are mainly reflected in the following aspects:

[0032] 1. The utility model can realize the automatic folding of the cuff and complete the sewing of the cuff fabric and the sleeve fabric;

[0033] 2. The utility model improves the sewing quality of the cuff fabric and the sleeve fabric by providing a pressing mechanism;

[0060] Reference Figure 6 A connecting rod 18 is fixed on the end of the connecting block 16 that is not connected to the output shaft of the eighth driving unit 17, and a U-shaped pressing plate 19 is fixed on the end of the connecting rod 18. The pressing plate 19 presses the sleeve fabric placed on the base plate 2.

[0061] Reference Figure 1 、 Figure 6 and Figure 11 The frame 1 is also equipped with a material return mechanism 5, which is used to move the stitched cuff and sleeve fabrics out of the base plate 2.

A channel 55 is formed between the material return component 2 52 and the material return component 1 51, and the end of the sleeve fabric is located in the channel 55. Initially, the first stripping piece 51 is away from the frame 1 , and the second stripping piece 52 is close to the frame 1 .

[0062] Reference Figures 1-11 The complete sewing steps of this sleeve fork machine are as follows:

[0063] The staff first places the sleeve fabric on the base plate 2. The output shaft of the third drive unit 34 extends, driving the sliding seat 1 33 to slide along the X-axis, allowing the metal pressing plate 1 35 to move above the folding groove 21. The output shaft of the second drive unit 32 then extends, driving the first mounting plate 31 to rotate. This rotation of the first mounting plate 31 rotates the metal pressing plate 1 35, causing it to press a portion of the sleeve fabric into the folding groove 21. The end of the sleeve fabric that is not pressed into the folding groove 21 rises, forming a warped edge. The output shaft of the fifth cylinder 14 then extends, causing the Y-shaped pressing block 15 to descend and press the metal pressing plate 1 35, allowing the metal pressing plate 1 35 within the folding groove 21 to effectively press the sleeve fabric, preventing some of the sleeve fabric from being left unpressed.

[0064] The output shaft of the fourth drive unit 92 then extends, driving the hemming push plate 91 to move, causing the hemming plate to push the warped edge of the sleeve fabric against the metal pressure plate 1 35, bending the warped edge to form a hem, and completing the hem shaping of the sleeve fabric. After the hem of the sleeve fabric is shaped, the output shaft of the fourth drive unit 92 retracts to control the hemming push plate 91 to move back to its original position. The output shaft of the fifth cylinder 14 retracts, causing the Y-shaped pressing block 15 to rise and no longer press on the metal pressure plate 1 35. The output shaft of the third drive unit 34 then retracts, causing the sliding seat 1 33 to move back to its original position, allowing the metal pressure plate 1 35 to be withdrawn from the hemmed sleeve fabric. The output shaft of the second drive unit 32 then retracts, driving the first mounting plate 31 to flip and reset in preparation for the next hem shaping of the sleeve fabric.

[0065] After the cuff hem is folded, the worker places the sleeve fabric on top of the hemmed cuff fabric, allowing one end of the sleeve fabric to hang down into the channel 55. The output shaft of the seventh drive unit 44 then extends, driving the second sliding seat 43 to slide along the X-axis, allowing the second metal pressing plate 45 to move above the folding groove 21. The output shaft of the sixth drive unit 42 then extends, driving the second mounting plate 41 to flip, causing the second metal pressing plate 45 to flip down and press against the cuff fabric and the sleeve fabric. This prevents relative displacement of the sleeve and cuff fabrics during sewing, which could affect sewing quality.

[0066] While the metal pressing plate 2 45 presses the connection between the cuff fabric and the sleeve fabric, the output shaft of the eighth driving unit 17 extends to drive the connecting block 16 to flip, so that the pressing plate 19 falls and presses the sleeve fabric around the folding groove 21, and together with the metal pressing plate 2 45 prevents the movement of the sleeve fabric.

[0067] After the metal pressing plate 2 45 and the pressing plate 19 press the cuff fabric and the sleeve fabric, the X-axis moving platform 11 and the Y-axis moving platform 12 drive the base plate 2 and the sewing head 13 to move so that the sewing head 13 sews the pressed cuff fabric and the sleeve fabric.

[0068] After the sewing head 13 has sewn a portion of the sleeve fabric and the cuff fabric, the sewing head 13 stops sewing because the metal pressing plate 2 45 blocks the sewing path of the sewing head 13. At this time, the output shaft of the seventh driving unit 44 retracts to drive the second mounting plate 41 to flip and reset, causing the metal pressing plate 2 45 to flip and lift. Then the output shaft of the sixth driving unit 42 retracts, causing the sliding seat 2 43 and the metal pressing plate 2 45 to slide and reset a short distance. Then the output shaft of the seventh driving unit 44 extends to flip the second mounting plate 41, causing the metal pressing plate 2 45 to flip and descend and press the sleeve fabric and cuff fabric again, so that the metal pressing plate 2 45 avoids the sewing path of the sewing head 13.

[0069] Then the output shaft of cylinder twelve 81 extends, carrying the fixed plate 82 and multiple thimbles 83 upward, so that the heads of the multiple thimbles 83 are slightly exposed from the multiple through holes 71 and contact with the sleeve fork fabric, so that a certain friction force is generated between the two. When the sleeve fabric and the sleeve fork fabric are sewn, the sleeve fork fabric is pulled to prevent the sleeve fabric from moving around, thereby assisting the pressing mechanism 4 to ensure the sewing quality of the sleeve fabric and the sleeve fork fabric.

[0070] Next, the X-axis moving platform 11 and the Y-axis moving platform 12 drive the base plate 2 and the sewing head 13 to move, allowing the sewing head 13 to re-sew the compressed cuff and sleeve fabrics. After the cuff and sleeve fabrics are sewn together, the output shaft of the sixth drive unit 42 retracts, causing the second mounting plate 41 to flip back to its original position, causing the second metal pressing plate 45 to rotate and lift. Then, the output shaft of the seventh drive unit 44 retracts, causing the second sliding seat 43 and the second metal pressing plate 45 to move back to their original position.

[0071] Then the output shaft of the tenth driving part 53 retracts to control the material stripping piece 1 51 to slide toward the frame 1, and the eleventh driving part 54 controls the material stripping piece 2 52 to move away from the frame 1. When the material stripping piece 2 52 and the material stripping piece 1 51 move, they will pull the sleeve fabric to move away from the bottom plate 2, and finally hang on the material stripping piece 2 52, completing the automatic stripping of the sleeve fabric after stitching.

[0072] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
