Abstract
Description
Technical Field
[0001] This utility model relates to the field of garment sewing technology, and in particular to a pocket processing device for concealed stitching using a pocket opening machine. Background Technology
[0002] In garment manufacturing, opening pockets is an essential step, primarily used to create pockets in specific locations on clothing for carrying small items such as mobile phones and wallets. The process involves first separately processing the pocket opening and the pocket lip, then sewing the lip onto the opening to complete the opening. The processing of the pocket opening requires cutting, folding, shaping the lip, and sewing. Cutting involves creating an "H" or "Y" shaped slit at the pocket opening; folding involves folding the cut opening inwards to form a folded edge; shaping the lip involves placing the lip on the folded edge; and finally, sewing. For example, patent application CN202010348853.X discloses a pocket-opening machine for garment pocket processing; and patent application CN202011214831.0 discloses a continuous production garment pocket-opening machine.
[0003] Currently, during bag processing, in order to improve the structural strength and durability of the bag and prevent problems such as unraveling and deformation during use or washing, a looper technique is generally used to reinforce the edges of the bag opening. However, for fabrics with relatively loose warp and weft density, such as down jackets and denim, the dense stitching holes of the looper can damage the fabric during processing, thus affecting the processing quality of the bag. Utility Model Content

[0027] Example 1:
[0028] like Figures 1 to 7 As shown, a pocket processing device for concealed stitching using a pocket opening machine includes a sewing component, a laser cutting component, a fabric strip edging component 1, a folding knife component 4 disposed above the fabric strip edging component 1, and an outer pressure frame 2 disposed vertically opposite to the folding knife component 4. An inner pressure frame 3 is disposed on the outer pressure frame 2. The outer pressure frame 2 is movably disposed on the processing table of this embodiment. The outer pressure frame 2 is used to place the fabric of the pocket to be processed. The inner pressure frame 3 can move and press and fix the fabric on the outer pressure frame 2.
[0029] Specifically, the processing window 31 of the inner pressure frame 3 is correspondingly set to the material setting window 21 of the outer pressure frame 2, so that the fabric can be sewn, cut and processed through the processing window 31 in conjunction with the sewing component and the laser cutting component.
[0030] Furthermore, the outer pressure frame 2 is provided with a front and rear telescopic plate 22 connected to the front and rear telescopic cylinder 23 and a left and right telescopic plate 24 connected to the left and right telescopic cylinder 25. The front and rear telescopic plate 22 slides back and forth and the left and right telescopic plate 24 slides left and right and is set in the fixed material window 21 so as to provide an operating gap for subsequent pocket sewing processing through the telescopic sliding of the front and rear telescopic plate 22 and the left and right telescopic plate 24.
[0031] Furthermore, the front and rear telescopic plates 22 and the left and right telescopic plates 24 can also be driven by a cylinder on each side to achieve inward or outward telescopic sliding. For details, please refer to the utility model patent with application number 202020681381.5: a bag opening material fixing mechanism for clothing opening.
[0032] The fabric strip flanging assembly 1 has a lifting mounting plate 11 and a pressure plate 16 disposed on the mounting plate 11 and capable of lateral displacement. The fabric strip flanging assembly 1 has a lifting cylinder 12 that drives the mounting plate 11 to move up and down. The lifting cylinder 12 drives the mounting plate 11 and the pressure plate 16 to move up and down. The fabric strip 5 is placed on the pressure plate 16. The pressure plate 16 drives the fabric strip 5 to move downward and press against the fabric of the outer pressure frame 2.
[0033] The mounting plate 11 is equipped with a translation cylinder 14 that drives the slide plate 13 to move back and forth, and the mounting plate 11 is also equipped with a pressing cylinder 15 that drives the pressing plate 16 to move laterally. The translation cylinder 14 cooperates with the lifting cylinder 12 to press and fix the left and right sides of the fabric strip 5 onto the fabric inside the processing window 31. The pressing plate 16 is located on both sides of the slide plate 13 so that the pressing plate 16 on both sides can be driven to move laterally inward or outward by the pressing cylinder 15.
[0034] The pressing plate 16 is provided with a pressing surface for pressing the fabric strip 5 and an abutting surface located outside the pressing surface for folding the left and right edges 51 of the fabric strip 5 inward. Specifically, the pressing plate 16 is provided with a pressing plate 161 and an abutting plate 162 facing each other inside and outside, and a slot 163 for locking the fabric strip 5 is provided between the pressing plate 161 and the abutting plate 162. The left and right sides of the fabric strip 5 to be processed are locked by the slots 163 of the two pressing plates 16.
[0035] The pressing surface is located on the bottom surface of the pressure plate 161, and the abutting surface is located on the inner side of the pressure plate 162. The pressure plate 161 is used to press the fabric strip 5 downward, that is, the pressure plates 161 on both sides can move downward and press and fix the two sides of the fabric strip 5 onto the fabric. It also cooperates with the sewing component and the laser cutting component to sew the left and right flanges 51 onto the fabric and laser open the bag, and remove the middle part of the fabric strip 5 by laser cutting.
[0036] Specifically, the fabric strip 5 inside the pressure plate 161 is first sewn onto the fabric along its width direction using a sewing assembly. Then, the fabric between the two pressure plates 161 is laser-cut to open the pocket using a laser cutting assembly. At the same time, the middle part of the fabric strip 5 is cut off, that is, the part between the left and right folded edges 51 is removed. The left and right folded edges 51 are then sewn onto the fabric of the open pocket using a sewing assembly.
[0037] This embodiment strengthens the structural strength of the left and right sides of the fabric pocket by sewing the left and right folded edges 51 together. This overcomes the defect of existing methods that require knotting to reinforce the pocket, where the needle holes easily damage the fabric. This ensures the processing quality and production efficiency of the pocket.
[0038] The abutment 162 is used to fold the left and right edges 51 of the fabric strip 5 inward, for reference. Figure 4 As shown, the abutment 162 drives the two pressing plates 16 to move inward by the pressing cylinder 15, that is, the abutment plates 162 on both sides fold inward and turn left and right edges 51.
[0039] The folding knife assembly 4 has a mounting base 41 that is raised and lowered, and left and right inserts 42 that are mounted on the mounting base 41 and correspond vertically to the left and right flanges 51. The left and right inserts 42 can move downward with the mounting base 41 and further fold the left and right flanges 51 downward.
[0040] Specifically, the mounting base 41 is equipped with a front and rear folding blade 44 that moves back and forth, and a left and right inserting blade cylinder 43 for driving the left and right inserting blades 42 to rise and fall. A puller 26 is slidably arranged on the outer pressure frame 2, which is vertically opposite to the left and right inserting blades 42. A puller cylinder 27 and a clamping plate 28 are arranged on the outer pressure frame 2 to drive the puller 26 to move laterally. The puller 26 is located between the material setting window 21 and the processing window 31. The puller cylinder 27 can drive the puller 26 to slide laterally, that is, the puller 26 can slide inward into the processing window 31.
[0041] The broach 26 has a slot 261 for the left and right insert blades 42 to pass through. When the broach 26 slides inward into the processing window 31, the left and right insert blades 42, the left and right flanges 51, and the slot 261 are arranged vertically and vertically. Thus, the left and right flanges 51 can be flipped down by the left and right insert blades 42 to pass through the corresponding slot 261. Then, the left and right insert blades 42 are driven to move upward to disengage from the slot 261.
[0042] When a "Y"-shaped slit appears in the fabric, the left and right folded edges of the fabric and the left and right folded edges 51 of the fabric strip 5 pass through the groove 261 together.
[0043] The pull cutter 26 slides outward to fold the left and right edges outward 51. At this time, the front and rear folding cutters 44 extend into the processing window 31 and move back and forth, thereby realizing the folding operation of the pocket.
[0044] The clip 28 is connected to the clip cylinder 29 and can be driven to press against the outer pressure frame 2. That is, the clip cylinder 29 drives the clip 28 to move and press against the bottom of the outer pressure frame 2 to hold the flange of the shaping bag.
[0045] The folding knife assembly 4 is then retracted, and the bag fabric and bag lip are placed in place. The bag is then sewn together using the sewing assembly.
[0046] This embodiment also discloses a method for processing pockets with concealed stitching using a pocket-opening machine, including the following steps:
[0047] 1) Place the fabric to be opened on the outer pressure frame 2, and set the cutting area on the fabric. Drive the inner pressure frame 3 to press down and cooperate with the outer pressure frame 2 to clamp the fabric, so as to press the fabric strip 5 down to the cutting area of the fabric.
[0048] 2) Move the outer pressure frame 2 to move the fabric and strip 5 to the sewing assembly, and sew the edge lines on the left and right flanges 51 to sew the fabric and strip 5 in place, that is, sew the left and right sides of the strip 5 to sew the fabric and strip 5 in place by sewing the left and right edge lines.
[0049] 3) Move the outer pressure frame 2 to the laser cutting component to cut the cutting area of the fabric to open the bag of the fabric, and cut off the middle part of the fabric strip 5, leaving the left and right folded edges 51 of the fabric strip 5 that are sewn to the fabric.
[0050] 4) Drive the tablet 16 to move inward so as to fold the left and right flanges 51 on both sides inward, and move downward through the left and right inserts 42 to fold the left and right flanges 51 downward.
[0051] 5) Move the outer pressure frame 2 to the folding knife assembly 4 to fold the fabric pocket, and fold the left and right folds 51 downwards to both sides. Then retract the clip 28 to clamp and fix the folds and left and right folds 51 of the fabric pocket, that is, the folds and left and right folds 51 of the folded pocket fabric.
[0052] 6) Sewing: Move the outer pressure frame 2 to the sewing assembly and sew it after placing the bag fabric and bag lip, that is, sew the fabric and the left and right folds 51, and then cut the material to complete the pocket processing.
[0053] Example 2:
[0054] The difference between this embodiment and embodiment 1 is that this embodiment does not include the pull cutter 26 and the pull cutter cylinder 27. Specifically, the mounting base 41 in this embodiment is provided with a front and rear folding cutter 44 that is arranged to move forward and backward, and the left and right insert cutters 42 are arranged to move laterally on the mounting base 41. The front and rear folding cutters 44 and the left and right insert cutters 42 extend into the processing window 31 through the lowering of the mounting base 41, and the left and right insert cutters 42 are driven to move laterally left and right to realize the downward folding and outward folding operation of the left and right flanges 51.
[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
