Description

Technical Field

[0001] This invention relates to the field of garment processing technology, and in particular to a single-sided adjustment processing mechanism for a pocket opening machine. Background Technology

[0002] In the garment manufacturing process, the pocket opening machine is an essential auxiliary processing machine. It is mainly used to form pockets in specific positions of the garment to facilitate carrying small items such as mobile phones and wallets. The current practice is to process the pocket opening and the pocket lip separately first, and then sew the pocket lip onto the pocket opening to complete the pocket opening.

[0003] Specifically, the garment is first placed on the outer pressure frame, and then pressed down by the small pressure frame to press the garment material onto the movable and stretchable fixed material sheet of the outer pressure frame to fix the garment material. Then, the pockets of the garment are cut, folded, shaped and sewn. Cutting means cutting a slit (such as a "Y" shaped slit) at the pocket. Folding the pocket means folding the cut pocket opening inward along the edge of the fixed material sheet to form a folded edge, and using clips to press the fixed material sheet upward to hold and fix the folded edge of the pocket. Shaping the folded edge means placing and pressing the folded edge of the pocket onto the folded edge of the pocket. Finally, the garment is sewn.

[0004] However, existing bag-opening machines can often only meet the processing needs of bags of specific sizes. When it is necessary to process bags of different sizes, it is usually necessary to manually disassemble and replace the corresponding specifications of the fixed material sheet, folding knife and other accessories, which makes the processing of bags of different sizes very inconvenient and increases the complexity of bag processing. Therefore, there is an urgent need for improvement. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a single-sided adjustment processing mechanism for a bag opening machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A single-sided adjustment processing mechanism for a bag opening machine includes a bag folding assembly and an outer pressure frame assembly arranged vertically opposite each other. The outer pressure frame assembly has an outer pressure frame and fixed material pieces distributed on the outer pressure frame and capable of retracting and extending backward under drive. One of the fixed material pieces can be adjusted relative to the other fixed material piece via a mounting plate. The bag folding assembly has a bag folding seat and front and rear folding blades distributed on the bag folding seat. One of the front and rear folding blades corresponds vertically to the mounting plate and can be adjusted relative to the other front and rear folding blades under drive. A telescopic folding blade capable of retracting and sliding is provided along the width direction of the front and rear folding blades.

[0008] Preferably, the front and rear fixed pieces are respectively connected to corresponding mounting plates, one of the mounting plates is fixedly mounted on the outer pressure frame, and the other mounting plate is slidably mounted on the outer pressure frame and driven to move back and forth by the drive plate.

[0009] Preferably, the drive plate is fixed with an adjusting gear plate that meshes with the adjusting gear transmission. The adjusting gear transmission is mounted on the adjusting motor and is used to drive the drive plate and the mounting plate to move back and forth.

[0010] Preferably, one side of the fixed piece is fixed to the fixed plate, and the mounting plate is equipped with a fixed piece cylinder for driving the fixed plate to move back and forth.

[0011] Preferably, the two fixed material pieces are provided with clamping parts opposite to each other, and the mounting plate is oscillatingly mounted with clamping pieces, the clamping pieces having abutting teeth that can be driven upward to press against the clamping parts.

[0012] Preferably, the folding bag holder is provided with a folding blade plate that is slidably connected to the front and rear of the adjusting rail and is used for corresponding installation of the front and rear folding blades. One of the folding blade plates is driven by a folding blade adjusting plate to adjust the front and rear folding blades on it to move back and forth.

[0013] Preferably, the folding knife adjustment plate is provided with inclined guide grooves, and an adjustment rod connected to the guide grooves is fixed on the folding knife plate corresponding to the folding knife adjustment plate. The folding knife adjustment plate is driven to move the corresponding folding knife plate back and forth through the guide grooves and the adjustment rods.

[0014] Preferably, the folding blade plate is equipped with a telescopic rail extending along the width direction of the front and rear folding blades, and the telescopic folding blades on the sides of the front and rear folding blades slide on the telescopic rail.

[0015] Preferably, the outer pressure frame is provided with a small pressure frame, the small pressure frame having a lifting plate that can be driven to move up and down, a pressure frame fixedly installed on the lifting plate, and a pressure frame sliding plate that is slidably installed on the lifting plate.

Pressure frame plate two corresponds to the mounting plate vertically and is adjusted for displacement by the pressure frame sliding plate.

[0016] Preferably, the small pressure frame is equipped with a pressure frame motor for driving the pressure frame gear to rotate, and the pressure frame slide plate is meshed with the pressure frame gear via the pressure frame tooth plate.

[0017] The beneficial effects of this invention are:

[0018] By setting a fixed piece that can be driven to adjust its displacement forward and backward on one side, and a front and rear folding blade that corresponds to the fixed piece and can be driven to adjust its displacement on one side, the invention utilizes unilateral electrical adjustment to adapt to the processing requirements of pockets of different sizes. Compared with the existing method that requires disassembly and replacement, the electrical adjustment method of the present invention is simpler and more efficient, and improves the efficiency of pocket processing.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0033] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0034] like Figures 1-12 As shown, a single-sided adjustment processing mechanism for a bag opening machine includes a bag folding assembly and an outer pressure frame assembly arranged opposite each other. The outer pressure frame assembly has an outer pressure frame 5 and fixed material pieces 51 distributed front and back on the outer pressure frame 5 and capable of forward and backward extension displacement when driven. The outer pressure frame 5 is used to place the garment to be processed. The two fixed material pieces 51 are slidably connected to the outer pressure frame 5 and form a fixed material window for processing the garment pocket between them.

[0035] One of the fixed material pieces 51 can be adjusted back and forth relative to the other fixed material piece 51 via the mounting plate 53. That is, the mounting plate 53 can drive the fixed material piece 51 on it to adjust its position back and forth. Specifically, the two fixed material pieces 51 are respectively connected to the corresponding mounting plates 53. There are two mounting plates 53 and two fixed material pieces 51, and they are set one-to-one. One of the mounting plates 53 is fixedly installed on the outer pressure frame 5. That is, the mounting plate 53 fixedly installed on the outer pressure frame 5 does not drive the fixed material piece 51 on it to adjust its position back and forth. The other mounting plate 53 is slidably installed on the outer pressure frame 5 and driven to move back and forth via the drive plate 562. That is, the mounting plate 53 slidably installed on the outer pressure frame 5 can drive the fixed material piece 51 on it to adjust its position back and forth. Thus, the fixed material piece 51 on the outer pressure frame 5 can be driven to adjust its position on one side, thereby adjusting the size of the fixed material window to adapt to the processing requirements of bags of different sizes and specifications.

[0036] Specifically, the drive plate 562 is slidably mounted on the outer pressure frame 5, and one end of the drive plate 562 is fixed on the mounting plate 53. An adjusting gear plate 563 that meshes with the adjusting gear 56 is fixed on the drive plate 562. The adjusting gear 56 is mounted on the adjusting motor 561 and is used to drive the drive plate 562 and the mounting plate 53 to move back and forth. That is, the adjusting motor 561 mounted on the outer pressure frame 5 drives the adjusting gear 56 to rotate, and through the adjusting gear 56 and the adjusting gear plate 563, the drive plate 562 and the mounting plate 53 are driven to move back and forth, thereby realizing the unilateral back and forth adjustment displacement of the fixed piece 51 on the mounting plate 53.

[0037] This embodiment adjusts the material set piece 51 on one side, that is, only one side is displaced and adjusted to adapt to the processing of bags of different sizes. Compared with double-sided adjustment (that is, both material set pieces 51 are displaced and adjusted), the adjustment accuracy of this embodiment is higher (because there will inevitably be a certain gap between the transmission structure, the error of double-sided adjustment will inevitably be greater than that of single-sided adjustment when adjusting the size of the material set window). Therefore, the single-sided adjustment of this embodiment can adapt to changing the size of the material set window while improving the adjustment accuracy of the size of the material set window.

[0038] One side of the fixed material piece 51 is fixed to the fixed plate 52. There are two fixed plates 52, which correspond one-to-one with the two fixed material pieces 51 distributed in front and behind. The mounting plate 53 is equipped with a fixed material piece cylinder 512 for driving the fixed plate 52 to move back and forth. The two fixed material piece cylinders 512 drive the fixed material piece 51 to move back and forth through the corresponding fixed plate 52, so that the two fixed material pieces 51 can move relative to each other.

[0039] When the pocket hem needs to be folded, the two fixed pieces 51 distributed at the front and back can be driven to move closer to each other. At this time, the front and back sides of the two fixed pieces 51 provide abutting folding edges for the pocket hem to be folded, so that the pocket hem can be folded along the edge of the fixed piece window. After the pocket folding operation is completed, the two fixed pieces 51 can be driven to move away from each other to provide a sewing gap for the subsequent pocket sewing operation.

[0040] The folding bag assembly has a folding bag base 1 and front and rear folding blades 23 distributed on the folding bag base 1. The folding bag base 1 can be driven to move up and down and drive the front and rear folding blades 23 to move up and down. There are two front and rear folding blades 23, which are installed below the folding bag base 1. One of the front and rear folding blades 23 corresponds vertically to the mounting plate 53 and can be driven to adjust its displacement relative to the other front and rear folding blade 23, thereby realizing the adjustment of the distance between the two front and rear folding blades 23, and thus adapting and processing pockets of different widths on one side.

[0041] The folding bag holder 1 is provided with a folding blade plate 2 that is slidably connected to the front and rear of an adjusting rail 21 and is used for corresponding installation of front and rear folding blades 23. The adjusting rail 21 extends front and rear and is fixed below the folding bag holder 1. There are two folding blade plates 2. The front and rear folding blades 23 are fixed one-to-one on the folding blade plate 2 and slidably connected to the adjusting rail 21 via the folding blade plate 2. One of the folding blade plates 2 is driven by a folding blade adjusting plate 14 to adjust the front and rear folding blades 23 back and forth, so that the front and rear folding blades 23 can achieve the adjustment of the front and rear folding blades 23. At the same time, the folding blade adjusting plate 14 can further drive the front and rear folding blades 23 to move back and forth, so as to realize the folding action of the front and rear folding blades 23. The other front and rear folding blade 23 can be driven to be connected to a cylinder, so that it can be driven to extend and retract back and forth by the cylinder, thereby realizing the folding action of the two front and rear folding blades 23.

[0042] The folding knife adjusting plate 14 has inclined guide grooves 141. The folding knife plate 2 corresponding to the folding knife adjusting plate 14 is fixed with an adjusting rod 22 connected to the guide grooves 141. That is, the folding knife plate 2 is connected to the guide grooves 141 of the folding knife adjusting plate 14 through the adjusting rod 22. Then, the folding knife adjusting plate 14 drives the corresponding folding knife plate 2 to move back and forth through the guide grooves 141 and the adjusting rod 22, so as to drive the front and rear folding knives 23 of the folding knife plate 2 to adjust their position back and forth.

[0043] Specifically, a second folding knife motor 13 is installed on the folding bag holder 1. The second folding knife motor 13 can be a servo motor. The second folding knife motor 13 is connected to the folding knife adjustment plate 14 via a transmission rod 131 and can drive the folding knife adjustment plate 14 to move left and right (refer to the screw drive structure). That is, the transmission rod 131 is driven to rotate forward and backward by the second folding knife motor 13 and drives the folding knife adjustment plate 14 to move left and right through the thread on the transmission rod 131. When the folding knife adjustment plate 14 slides left and right, the folding knife adjustment plate 14 drives the adjustment rod 22 and the folding knife plate 2 to move back and forth through the guide groove 141 on it. This allows adjustment of the relative position of the front and rear folding knives 23 on the folding knife plate 2 with the other front and rear folding knives 23, thereby realizing the unilateral adjustment of the distance between the two front and rear folding knives 23 and meeting the processing requirements of pockets of different widths. Compared with the existing method that requires disassembly and adjustment of folding knives, the electrical adjustment method of the front and rear folding knives 23 in this embodiment is simpler and more efficient.

[0044] Furthermore, this embodiment sets up a fixed material plate 51 that can be driven to adjust its displacement unilaterally, and front and rear folding blades 23 that are vertically corresponding to the fixed material plate 51 and can be driven to adjust their displacement unilaterally. This allows for unilateral electrical adjustment to adapt to the processing requirements of pockets of different sizes. Compared with the existing method that requires disassembly and replacement, the electrical adjustment method of the present invention is simpler and more efficient, and improves the efficiency of pocket processing.

[0045] A telescopic folding blade 26 capable of telescopic sliding is provided along the width direction of the front and rear folding blades 23. Specifically, a telescopic rail 24 extending along the width direction of the front and rear folding blades 23 is installed on the folding blade plate 2. The telescopic rail 24 is horizontally fixed on the folding blade plate 2. The telescopic folding blades 26 on the sides of the front and rear folding blades 23 telescopically slide on the telescopic rail 24. The telescopic folding blades 26 and the front and rear folding blades 23 are distributed in a straight line. The telescopic folding blades 26 are connected to the front and rear folding blades 23 via the telescopic rail 24. When the front and rear folding blades 23 move forward and backward, the telescopic folding blades 26 move forward and backward synchronously via the telescopic rail 24.

[0046] The telescopic folding blade 26 is distributed on both sides of the front and rear folding blades 23. The front and rear folding blades 23 and the telescopic folding blade 26 cooperate with each other to fold the front and rear pockets. The telescopic folding blade 26 can slide along the telescopic rail 24 to adjust the overall length of the folding blade.

[0047] Specifically, the folding bag holder 1 is provided with a sliding groove 122 and a slider 12 that can be driven to slide along the sliding groove 122. The folding bag holder 1 has a folding knife motor 11, which can be a servo motor. The folding knife motor 11 is connected to the slider 12 via a synchronous belt 111 and a lead screw 112, and drives the slider 12 to slide back and forth along the sliding groove 122. That is, the synchronous belt 111 drives the lead screw 112 to rotate in both directions through the folding knife motor 11, so as to drive the slider 12 to slide left and right.

[0048] The slider 12 is connected to the adjustment plate 25 of the telescopic folding blade 26 via the connecting rod 121. The telescopic folding blade 26 is installed at the lower end of the adjustment plate 25 and is flush with the lower ends of the front and rear folding blades 23. The connecting rod 121 is fixed to the slider 12 and is connected to the two telescopic folding blades 26 distributed at the front and rear.

[0049] The slide groove 122 is arranged parallel to the telescopic rail 24. When the slider 12 is driven to slide along the slide groove 122, the slider 12 drives the two telescopic folding blades 26 distributed in front and behind to slide left and right synchronously via the connecting rod 121, thereby adjusting the relative position with the front and rear folding blades 23.

[0050] In this embodiment, a telescopic folding blade 26 is provided on the side of the front and rear folding blades 23. The telescopic folding blade 26 can be driven to slide and cooperate with the front and rear folding blades 23 to adjust the overall length of the folding blade, thereby adapting to the processing needs of pockets of different lengths and sizes. Compared with the existing method that requires disassembling and replacing the folding blade, the adjustment method of the folding blade in this embodiment is simpler and more efficient, and improves the processing efficiency of the pocket invisibly.

[0051] To ensure the folding effect of the folding knife, the telescopic folding knife 26 is provided with an extension piece 261 that fits against the front and rear folding knives 23. When the telescopic folding knife 26 slides left and right, the telescopic folding knife 26 can always fit against the front and rear folding knives 23 through the extension piece 261, thereby allowing the front and rear folding knives 23 and the telescopic folding knife 26 to have a larger contact area and fold the front and rear edges of the bag, so as to achieve a better folding effect.

[0052] The outer pressure frame 5 is provided with a small pressure frame 3. The small pressure frame 3 has a lifting plate 31 that can be driven to move up and down, a pressure frame 32 fixedly installed on the lifting plate 31, and a pressure frame slide plate 4 that is slidably installed on the lifting plate 31. The pressure frame slide plate 4 can be driven to move back and forth relative to the pressure frame 32. The lifting plate 31 is connected to a lifting plate cylinder 311. The lifting plate 31 is driven to move up and down by the lifting plate cylinder 311, and drives the pressure frame 32 and the pressure frame slide plate 4 to move up and down synchronously.

[0053] A first pressure frame plate 33 and a second pressure frame plate 41 are respectively fixed on the pressure frame 32 and the pressure frame slide plate 4. A pocket processing window is formed between the first pressure frame plate 33 and the second pressure frame plate 41. The second pressure frame plate 41 is vertically aligned with the mounting plate 53 and is adjusted and displaced by the pressure frame slide plate 4. The relative distance between the first pressure frame plate 33 and the second pressure frame plate 41 determines the width of the processing window. The second pressure frame plate 41 is displaced relative to the first pressure frame plate 33 by the pressure frame slide plate 4 to adjust the width of the processing window on one side.

[0054] The small pressure frame 3 is equipped with a pressure frame motor 431 for driving the pressure frame gear 43 to rotate. The pressure frame motor 431 can be a servo motor and is fixedly installed on the small pressure frame 3. The pressure frame slide plate 4 is driven and meshed with the pressure frame gear 43 via the pressure frame tooth plate 42. The pressure frame gear 43 is installed on the drive end of the pressure frame motor 431. The pressure frame tooth plate 42 is fixed on the pressure frame slide plate 4 and is driven by the pressure frame gear 43 to adjust the displacement of the pressure frame tooth plate 42, the pressure frame slide plate 4, and the pressure frame plate 41 back and forth.

[0055] Furthermore, the second pressure plate 41 can be driven to adjust its displacement relative to the first pressure plate 33 to adapt to the size of the processing window on one side, thus meeting the processing needs of pockets of different widths. Compared with the existing method of disassembling and replacing small pressure plates 3 of different specifications, the adaptation method of this embodiment is simpler and more efficient.

[0056] Furthermore, this embodiment achieves higher adjustment accuracy by adjusting the second pressure plate 41 on one side compared to double-sided adjustment (i.e., both the first pressure plate 33 and the second pressure plate 41 are adjusted for displacement). (Since there will inevitably be a certain gap between the transmission structures, the error of double-sided adjustment will inevitably be greater than that of single-sided adjustment when adjusting the size of the processing window on both sides.) Thus, the single-sided adjustment in this embodiment can adaptably change the size of the processing window while improving the accuracy of the adjustment of the size of the processing window.

[0057] A frame pressing cylinder 44 is installed on the frame pressing slide plate 4. The frame pressing plate 2 41 slides up and down on the side wall of the frame pressing slide plate 4. The frame pressing cylinder 44 is connected to the frame pressing plate 2 41 via a connecting plate 45 and can drive the frame pressing plate 2 41 to move up and down. Thus, the frame pressing plate 2 41 can be driven by the frame pressing cylinder 44 to move up and down relative to the frame pressing plate 1 33.

[0058] By setting up independent pressure plate 1 33 and pressure plate 2 41, pressure plate 2 41 can form a pressure surface with different heights with pressure plate 1 33. Then, by cooperating with pressure plate 1 33 and pressure plate 2 41 which is raised and lowered, the pocket fold and the pocket lip placed on one side of the fold can be effectively pressed and sewn.

[0059] Specifically, during garment pocket processing, it is sometimes necessary to process single-pocket lip pockets according to the actual needs of the garment. The overall thickness of the fabric at the folded edge of the pocket where the single-pocket lip is placed is relatively thick. If a small press frame with a uniform pressing surface height is used to press the pocket, it is easy for the small press frame to be unable to press the entire pocket tightly. In this embodiment, by setting press frame plate 1 33 and press frame plate 2 41 with different pressing surface heights, the above-mentioned single-pocket lip pocket can be pressed more effectively and reliably, thereby ensuring the sewing quality of the pocket.

[0060] The outer pressure frame 5 is equipped with a clamping piece 6 that is openable and closable. The two fixed pieces 51 are provided with clamping parts 511 facing each other. The clamping parts 511 and the fixing plate 52 are distributed on both sides of the fixed pieces 51, and the clamping parts 511 are suspended vertically. When the pressure frame plate 33 and the pressure frame plate 41 on the small pressure frame 3 are driven to move downward and press against the fixed pieces 51 on the outer pressure frame 5, the clamping parts 511 can be compressed and deformed slightly downward, and can cooperate with the clamping piece 6 below the fixed pieces 51, so that the fixed pieces 51 and the clamping pieces 6 can clamp the pocket flange more stably, thereby improving the clamping effect on the pocket flange. At the same time, the clamping parts 511 can be compressed and deformed to avoid affecting the stability of the fixed pieces 51 installation due to frequent compression, thus improving the reliability of pocket processing.

[0061] Specifically, two clips 6 are oscillatingly mounted on the mounting plate 53 and are distributed one-to-one below the fixed material plate 51. The clips 6 can be driven to swing up and down. The clips 6 have abutting teeth 61 that can be driven to press upward against the clamping part 511 to clamp and fix the folded edge of the pocket.

[0062] Furthermore, the abutment teeth 61 are elongated and spaced along the length of the clamping part 511. By providing abutment teeth 61 on the clamping piece 6 that correspond to the upper and lower parts of the clamping part 511, the abutment teeth 61 can deform and press against the clamping part 511 during the upward swinging clamping of the pocket fold. Thus, the deformation of the abutment teeth 61 can more stably press against and clamp the pocket fold, thereby improving the clamping and fixing effect of the pocket fold.

[0063] A slide block 54 is mounted on the mounting plate 53 and can be driven to slide back and forth on the mounting plate 53. The slide block 54 can move back and forth synchronously with the mounting plate 53. The slide block 54 is hinged to a hinge plate 62 for mounting the clamping piece 6 via a pin shaft 63. The clamping piece 6 is fixedly mounted on the hinge plate 62. The hinge plate 62 is driven to make the clamping piece 6 swing up and down relative to the fixed material piece 51.

[0064] A clamping cylinder 64 is rotatably mounted on the slide block 54. The drive connector 641 on the drive end of the clamping cylinder 64 is rotatably connected to the hinge plate 62. The clamping cylinder 64 drives the clamping piece 6 on the hinge plate 62 to swing upward and abut against the clamping part 511 of the fixed piece 51 to achieve the clamping and fixing of the pocket edge.

[0065] A clamping cylinder 55 is installed on the mounting plate 53. The driving end of the clamping cylinder 55 is connected to the slide block 54 and can drive the slide block 54 to move the clamping piece 6 back and forth. That is, the clamping cylinder 55 can drive the clamping piece 6 away from the fixed piece 51 through the slide block 54 to avoid the clamping piece 6 interfering with the folding operation of the bag. When it is necessary for the clamping piece 6 to clamp and fix the folded edge of the bag, the clamping cylinder 55 can drive the clamping piece 6 to move below the fixed piece 51, and the clamping cylinder 64 can drive the clamping piece 6 to press upward to clamp the folded edge of the bag.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
