[0039] In one embodiment of this utility model, such as Figures 1-4As shown, a patching device for a double-layered padding pocket includes a worktable 1, a folding mechanism 2, a transferring mechanism 3, and a sewing mechanism 4 disposed on the worktable 1. The worktable 1 has a folding area 11 and a sewing area 12. The folding area 11 has a contoured notch 131, and a contoured base plate 132 that can move vertically is embedded in the contoured notch 131. When the contoured base plate 132 moves downward, it forms a downwardly recessed contoured groove with the contoured notch 131 to fix the bottom padding. The folding mechanism 2 includes a movable contoured tongue 21, which can extend into or out of the folding area 11 and fold the top padding over the top surface of the bottom padding. The transferring mechanism 3 includes a movable pressing plate 31, which can press the two layers of padding after folding and transfer the double-layered padding to the sewing area 12. The sewing mechanism 4 includes a sewing machine head disposed in the sewing area 12. When the contour base plate 132 moves downward, it is lower than the workbench 1 and forms a contour groove with the contour notch 131. The contour groove provides space for the bottom padding cloth and the side wall of the contour groove acts on the edge of the bottom padding cloth, thereby fixing the relative position of the bottom padding cloth in the stacking area 11, which facilitates the subsequent stacking of the top padding cloth. When the contour base plate 132 moves upward, it is flush with the workbench 1. The raised contour base plate 132 can make the bottom padding cloth and the bottom surface of the contour tongue plate 21 abut against each other, thereby completing the stacking action of the double padding cloth. On the other hand, the flush workbench provides space for the clothing fabric to be laid flat, so as to meet the processing requirements of the clothing fabric patching process. Compared with the prior art, this application uses a movable contouring base plate 132 to form a recessed contouring groove and a flat table surface in the overlapping area 11 of the worktable 1, thereby meeting the processing requirements of double-layer padding pockets and the processing requirements of patching pockets where a single layer padding is directly sewn onto clothing, which is conducive to broadening the applicable scenarios of the patching device.Specifically, the processing steps of the double-layer padding bag in this embodiment are as follows: (1) Place the bottom padding, the contoured bottom plate 132 in the stacking area moves downward and forms a contoured groove with the contoured notch 131, and the bottom padding is placed in the contoured groove manually; (2) Place the top padding, the contoured tongue plate 21 extends into the stacking area 11, and the top padding is placed on the top surface of the contoured tongue plate 21 manually, at which time the outer edge of the top padding is exposed on the edge of the contoured tongue plate 21; (3) Fold and stack, firstly the contoured top plate 23 and several folding plates 24 move synchronously to the end close to the contoured tongue plate 21 until the contoured top plate 23 contacts the top padding on the contoured tongue plate 21, and then the several folding plates 24 act on the outer edge of the top padding, causing it to fold downward and fit together. On the bottom surface of the contoured tongue plate 21, the contoured top plate 23 and several folded edge plates 24 and the contoured tongue plate 21 move synchronously towards the end close to the contoured groove until the bottom surface of the contoured several folded edge plates 24 contacts the top surface of the bottom padding cloth. Finally, the several folded edge plates 24 are pulled outward and reset with the contoured top plate 23 towards the end away from the contoured tongue plate 21; (4) Transfer of stacked material, the pressing plate 31 moves towards the stacking area 11 until it is directly above the stacked material, the pressing plate 31 moves downward until it presses against the stacked material, then the contoured tongue plate 21 pushes out of the stacking area 11, and finally the pressing plate 31 drives the stacked fabric to move towards the end close to the sewing area 12; (5) Sewing, the sewing machine head of the sewing mechanism 4 acts on the stacked material; thus completing the sewing of the double-layer padding bag. The processing steps of the patching process in this embodiment are as follows: (1) Place the clothing fabric, the imitation base plate 132 in the stacking area moves upward and is flush with the table surface of the workbench 1, and the clothing fabric is placed on the table surface of the workbench 1 by hand; perform the processing steps (2) to (5) of the double-layer padding pocket mentioned above in this embodiment; and then complete the sewing of the pocket on the clothing fabric.

[0040] In one embodiment of this utility model, such as Figures 2-3 As shown, the overlapping area 11 is recessed and has a cavity 15 corresponding to the contour notch 131. A lifting drive 16 is provided within the cavity 15. The output end of the lifting drive 16 is connected to the bottom side of the contour base plate 132 and can drive the contour base plate 132 to move vertically. Specifically, it also includes a shape-changing plate 13 and a hollow shell 14 with a top opening. The overlapping area 11 has an assembly slot corresponding to the shape-changing plate 13. The hollow shell 14 is screwed onto the bottom side of the assembly slot to form the cavity 15. The shape-changing plate 13 is detachably fixed to the top side of the assembly slot with screws to cover the cavity 15. The contour notch 131 is formed on the shape-changing plate 13. By using a detachable structure to replace the shape-changing plate 13 and the contour base plate 132, the fixing requirements of more bag shapes can be met, improving the applicability of this embodiment.

[0041] In one embodiment of this utility model, such as Figures 2-3 As shown, the lifting drive 16 is a cylinder horizontally arranged in the cavity 15. The bottom of the contoured base plate 132 extends downwards with a lifting slider 1321. The lifting slider 1321 has a through groove 1322 with an opening at the bottom end. The piston rod of the cylinder is provided with a push-pull slider 161. The push-pull slider 161 includes a front block 1611 and a rear block 1612 connected together. The thickness of the front block 1611 is equal to the depth of the through groove 1322. The thickness of the rear block 1612 is greater than the depth of the through groove 1322. A first inclined surface 1613 is provided at the connection between the rear block 1612 and the front block 1611. A second inclined surface 1323 facing the first inclined surface 1613 is provided on the top edge of the through groove 1322. Specifically, the cylinder is horizontally fixed to the bottom wall of the hollow housing 14 by screws. The vertical height difference between the front block 1611 and the rear block 1612, along with the horizontal pushing and pulling force of the piston rod in conjunction with the cylinder, drives the lifting slider 1321 to move vertically. This structure achieves stroke control, reducing the requirements for selecting the correct cylinder stroke. Correspondingly, when the bottom padding needs to be fixed, the bottom end of the lifting slider 1321 abuts against the bottom wall of the hollow housing 14. The slot 1322 is located on the front block 1611. When it is necessary to fix the clothing fabric, the piston rod of the cylinder pushes out the first inclined surface 1613 and slides into the second inclined surface 1323. The rear block 1612 squeezes and acts on the lifting slider 1321 to make it rise in the vertical direction, so as to drive the contouring base plate 132 to fill the contouring gap 131 on the shape changing plate 13. In the aforementioned state, the slot 1322 is located on the rear block, and the rear block 1612 continuously provides vertical support force for the contouring base plate 132.

Vertically arranged dovetail grooves are respectively formed on both sides of the lifting slider 1321, and dovetail blocks that slide in conjunction with the dovetail grooves are formed on the inner side of the guide seats 141. Specifically, the pair of guide seats 141 are respectively fixed to the bottom wall of the hollow shell 14 by screws, and the sliding engagement of the dovetail blocks with the dovetail grooves improves the smoothness of the sliding of the lifting slider 1321.

[0043] In one embodiment of this utility model, such as Figures 2-3As shown, the bottom ring of the contouring base plate 132 is provided with several limiting pieces 1324. Specifically, the limiting pieces 1324 are rectangular, and their inner ends are fixed to the contouring base plate 132 by welding. When the contouring gap 131 is filled, the limiting pieces 1324 abut against the inner bottom surface of the shaping plate 13. The limiting pieces 1324 and the shaping plate 13 abut against each other to prevent the contouring base plate 132 from being higher than the top surface of the shaping plate 13 in this usage scenario.

[0044] In one embodiment of this utility model, such as Figures 2-3 As shown, the contoured base plate 132 has several adsorption holes 1325 along its outline. The bottom of the cavity 15 is provided with a first tube, the bottom end of which is connected to the vacuum port of the vacuum generator via an air pipe.
