Description
Technical Field
[0001] This utility model belongs to the technical field of bag opening machines, and relates to a garment pocket folding mechanism with strong adaptability and high stability. Background Technology
[0002] In the garment manufacturing industry, fully automatic laser pocket opening machines play a vital role as automated sewing equipment for making pockets on clothing. Their typical processing technology is as follows: First, the fabric is opened, creating two symmetrical long folds front and back, and two symmetrical short folds left and right. Next, the fabric at the opening is folded. Then, the pocket lip is placed, and the sewing process is completed. During the folding step, the long and short folds are folded to the lower fixing plate by a folding mechanism, which ultimately secures the folds.
[0003] However, existing fully automatic laser bag opening machines have certain limitations. Because the thickness of the fabric being sewn varies each time, it is difficult to precisely control the lifting mechanism of the folding mechanism to adapt to different fabric specifications. The front and rear folding blades and left and right folding blades of the folding mechanism are all set in pairs, requiring a high degree of synchronization during operation, which is difficult for existing folding mechanisms to meet. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a highly adaptable and stable garment pocket folding mechanism.
[0005] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

The two actuators of the front and rear pneumatic fingers are respectively connected to front and rear pull rods, which are respectively connected to front and rear folding knife adjusting seats. Front and rear folding knives are mounted on the front and rear folding knife adjusting seats. The front and rear pneumatic fingers drive the front and rear pull rods, the front and rear folding knife adjusting seats, and the front and rear folding knives to move relative to each other in the front-rear direction. The two actuators of the left and right pneumatic fingers are respectively connected to left and right pull rods, which are respectively connected to left and right folding knife adjusting seats. Left and right folding knives are mounted on the left and right folding knife adjusting seats. The left and right pneumatic fingers drive the left and right pull rods, the left and right folding knife adjusting seats, and the left and right folding knives to move relative to each other in the left and right direction.
[0007] In the above-mentioned highly adaptable and stable garment pocket folding mechanism, the front and rear pneumatic fingers and the left and right pneumatic fingers are fixed above the folding knife mounting plate, the front and rear folding knife adjusting seats and the left and right folding knife adjusting seats are slidably disposed at the bottom of the folding knife mounting plate, and the folding knife mounting plate is provided with front and rear clearance holes to avoid the movement trajectory of the front and rear pull rods and left and right clearance holes to avoid the movement trajectory of the left and right pull rods. Preferably, the front and rear clearance holes are open holes and the left and right clearance holes are closed holes.
[0008] In the aforementioned highly adaptable and stable garment pocket folding mechanism, the left and right folding knife adjusting seat includes a third seat and a fourth seat. The third seat is connected to left and right pull rods, and the fourth seat is equipped with left and right folding knives. The fourth seat slides vertically on one side of the third seat. A small cylinder for driving the fourth seat to slide is provided between the third seat and the fourth seat. Furthermore, the cylinder body of the small cylinder is fixed to the bottom of the third seat, and its piston rod is connected to the fourth seat.
[0009] In the above-mentioned highly adaptable and stable garment pocket folding mechanism, the front and rear folding knife adjustment seat includes a first seat and a second seat. The first seat is connected to the front and rear pull rods, and the second seat is equipped with the front and rear folding knives. The first seat is provided with a vertical fine-tuning strip hole, and the second seat is adjustablely fixed in the fine-tuning strip hole by fasteners. Preferably, the fine-tuning strip holes are arranged in pairs.
[0010] In the above-mentioned highly adaptable and stable garment pocket folding mechanism, the front and rear folding blades are detachably connected to the second base. The second base is provided with a plurality of mounting holes for mounting the front and rear folding blades. The axes of the mounting holes are located on the same horizontal plane. The mounting holes are evenly distributed and cover the entire lateral range. The front and rear folding blades are provided with transversely distributed strip mounting grooves. The front and rear folding blades are fixed by fasteners that pass through the mounting holes and the strip mounting grooves.
[0011] In the above-mentioned highly adaptable and stable garment pocket folding mechanism, the front and rear folding blades are modularly assembled, including one or more folding blade units, and the folding blade units have the same specifications; the same specifications mean that the folding blade units have the same size and shape; preferably, the folding blade units are selected from one, two and three, respectively corresponding to small pockets, medium pockets and large pockets.

[0014] Compared with the prior art, this utility model has the following advantages:
[0015] 1. This utility model provides a highly adaptable and stable garment pocket folding mechanism. The lifting motor module drives the folding blade mechanism, resulting in better flexibility in its lifting control and adaptability to folding pockets made of fabrics of varying thicknesses. This utility model utilizes front and rear pneumatic fingers to drive the front and rear folding blades, and left and right actuating fingers to drive the left and right folding blades. Compared to existing cylinder-driven structures, this results in better synchronization of the relative movement of the folding blades, producing pockets of consistent width and faster folding speed. Therefore, compared to existing folding mechanisms, this utility model offers greater adaptability and higher stability.
[0016] 2. In existing technologies, the folding knife size is fixed. A folding knife of a specific size is only suitable for processing folded pockets with a length range similar to that of the folding knife, making it difficult to meet the processing needs of most pocket sizes. When processing pockets of different sizes, only custom-made folding knives can be used, which not only delays the production schedule but also increases production costs. This utility model adopts a modular folding knife design, using different numbers of folding knife units according to the size of the pocket. Attached Figure Description

[0024] A highly adaptable and stable garment pocket folding mechanism includes:
[0025] Gantry 24, which is installed on a fully automatic laser bag opening machine.
[0026] The lifting motor module 1 moves left and right along the slide rail on one side of the gantry frame 24. The lifting motor module 1 is fixed on the folding mechanism mounting frame 23, which slides left and right on the gantry frame 24 of the bag opening machine.

The left and right pneumatic fingers 4 drive the left and right pull rods 8, the left and right folding blade 10 adjustment seats 9 and the left and right folding blades 10 to move relative to each other in the left and right directions.
[0030] Comparison Appendix Figure 1 and attached Figure 2 The working process of this embodiment is as follows: After the bag opening machine opens the bag, the power unit drives the folding mechanism mounting frame 23 to move to the left along the slide rail on the gantry frame 24. The lifting motor module 1, the front and rear folding blade 7 assembly, and the left and right folding blade 10 assembly move to the left accordingly. At the same time, the lifting motor module 1 drives the folding blade mounting plate 2 to move downward. The front and rear folding blade 7 assembly and the left and right folding blade 10 assembly move downward accordingly. After reaching the fabric piece, the front and rear pneumatic fingers 3 drive the front and rear folding blade 7 to open the corresponding fabric piece. Then, the left and right pneumatic fingers 4 drive the left and right folding blade 10 to open the corresponding fabric piece. After the sewing is completed, the front and rear pneumatic fingers 3 drive the front and rear folding blade 7 to retract. Then, the left and right pneumatic fingers 4 drive the left and right folding blade 10 to retract. Both of them rise under the action of the lifting motor module 1, and the folding action is completed.
[0031] Comparison Appendix Figure 3 In this embodiment, the specific driving structure of the front and rear folding blade 7 assembly and the left and right folding blade 10 assembly is as follows: the front and rear pneumatic fingers 3 and the left and right pneumatic fingers 4 are fixed above the folding blade mounting plate 2; the front and rear folding blade 7 adjustment seat 6 and the left and right folding blade 10 adjustment seat 9 are slidably disposed at the bottom of the folding blade mounting plate 2; the folding blade mounting plate 2 is provided with front and rear clearance holes 11 for avoiding the movement trajectory of the front and rear pull rods 5 and left and right clearance holes 12 for avoiding the movement trajectory of the left and right pull rods 8. Preferably, the front and rear clearance holes 11 are open holes, which can increase the movement stroke of the front and rear pull rods 5; and the left and right clearance holes 12 are closed holes, which can increase the structural strength of the folding blade mounting plate 2.
[0032] Comparison Appendix Figure 4 The front and rear folding blade 7 assembly in this embodiment further includes: the front and rear folding blade 7 adjustment seat 6 includes a first seat 13 and a second seat 14. The first seat 13 is connected to the front and rear pull rods 5, and the second seat 14 is equipped with the front and rear folding blades 7. The first seat 13 is provided with a vertical fine-tuning slot 15, and the second seat 14 is adjustablely fixed in the fine-tuning slot 15 by fasteners. Preferably, the fine-tuning slots 15 are provided in pairs. By providing the fine-tuning slots 15, the lowering position of the front and rear folding blades 7 can be finely adjusted.
[0033] Comparison Appendix Figure 5The left and right folding blade 10 assembly of this embodiment further includes: the left and right folding blade 10 adjusting seat 9 includes a third seat 16 and a fourth seat 17, the third seat 16 is connected to the left and right pull rods 8, the fourth seat 17 is equipped with the left and right folding blades 10, the fourth seat 17 slides in the vertical direction on one side of the third seat 16, and a small cylinder 18 for driving the fourth seat 17 to slide is provided between the third seat 16 and the fourth seat 17; furthermore, the cylinder body of the small cylinder 18 is fixed to the bottom of the third seat 16, and its piston rod is connected to the fourth seat 17; by providing the small cylinder 18, the left and right folding blades 10 can be synchronously aligned with the lowered position of the front and rear folding blades 7.
[0034] With the above structure, the folding process can be further optimized. When the front and rear folding blades 7 descend to the fabric, the front and rear pneumatic fingers 3 immediately open. The small cylinder 18 immediately descends to make the left and right folding blades 10 reach the fabric position, and the left and right pneumatic fingers 4 immediately open. At this time, the front and rear pneumatic fingers 3 retract first, and the left and right pneumatic fingers 4 retract then.
[0035] This embodiment also provides a modular design for the front and rear folding blades 7 to accommodate the sewing of more pocket sizes, specifically:
[0036] The aforementioned front and rear folding blades 7 are detachably connected to the second base 14. The second base 14 is provided with a plurality of mounting holes 19 for mounting the front and rear folding blades 7. The axes of the mounting holes 19 are located on the same horizontal plane. The mounting holes 19 are evenly distributed and cover the entire lateral range. The front and rear folding blades 7 are provided with transversely distributed strip-shaped mounting grooves 20. The front and rear folding blades 7 are fixed by fasteners that pass through the mounting holes 19 and the strip-shaped mounting grooves 20.
[0037] Furthermore, the front and rear folding blades 7 are modularly assembled, including one or more folding blade units, which have the same specifications; the same specifications mean that the folding blade units have the same size and shape; preferably, the folding blade units are selected from one, two, and three, respectively corresponding to small pockets, medium pockets, and large pockets.
[0038] The modular design of the front and rear folding blades (7 units) works as follows: when processing small-sized pockets, only one folding blade unit needs to be installed; when processing medium-sized pockets, another folding blade unit is added on top of the original unit; and when processing large-sized pockets, an additional folding blade unit is added on top of the medium-sized pocket unit. The mounting holes (19) covering the entire horizontal range ensure the secure installation of any number of folding blade units. This structure allows for modularization of pocket sizes. Compared to traditional methods where a single mold can only process similar sizes, and a single machine may require more than a dozen molds to process various pockets, this modular design makes installation and replacement much easier and reduces costs.
[0039] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
