Description

Technical Field

[0001] This utility model belongs to the field of bag-applying machine technology, specifically a redundant positioning mechanism for a bag-applying machine. Background Technology

[0002] The patch pocket machine is mainly used for sewing pockets on jeans, shirts, and other garments. It can complete both straight stitch and loop stitch in one operation and is also suitable for sewing other irregularly shaped parts in garment processing. The main components of the patch pocket machine include a folding mechanism, a pressing (sewing) mechanism, a feeding mechanism, and a sewing machine head, all located on the worktable. The fabric is placed on the worktable. The folding mechanism folds the edge of the pocket fabric towards the bottom and places it on the body fabric. The pressing mechanism presses the pocket fabric firmly onto the surface of the body fabric. The pressing mechanism moves across the worktable via the feeding mechanism, moving the body fabric and pocket fabric together to the sewing machine head for stitching.

[0003] Before folding the pocket fabric, the body fabric is not properly prepared. After the sewing machine head sews the pocket fabric and the body fabric together, the curvature of the body fabric will be affected, resulting in poor sewing quality of the pocket fabric and affecting subsequent processing steps. Summary of the Invention

[0004] This utility model addresses the aforementioned technical problems by providing a redundant positioning mechanism for a patching machine, which allows for excess fabric in the main body of the patch, thereby optimizing the stitching effect of the patch.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a redundant position mechanism for a bag-applying machine, including a redundant position mounting base installed on the frame and a redundant position mounting base installed below the worktable. A fixing plate is vertically mounted on the redundant position mounting base, and a pressing lifting seat is slidably mounted on the front side of the fixing plate. A first pressing plate and a second pressing plate are provided below the pressing lifting seat. A first cylinder is provided on the rear side of the fixing plate, and the drive rod of the first cylinder is connected to the first pressing plate and the second pressing plate. A second cylinder is provided below the redundant position mounting base, and the second cylinder is connected to a first top plate. The first top plate is located below the first pressing plate and the second pressing plate.

[0006] To optimize the above technical solution, the present invention also includes the following improved technical solutions.

[0007] The bottom of the aforementioned pressing and lifting seat has a first mounting groove. A first screw is provided at one end of the first pressing plate, and the first screw is inserted into the first mounting groove. A second screw is provided at one end of the second pressing plate, and the second screw is inserted into the first mounting groove. The distance between the first and second pressing plates is adjusted by adjusting the positions of the first and second screws within the first mounting groove. Adjusting the distance between the first and second pressing plates adjusts the amount of fabric used in the main body.

[0008] The aforementioned pressure lifting seat has a first limiting block on one side, and a first recessed mounting portion on the same side. The first limiting block is inserted into the first mounting portion. When the air source is cut off, the air pressure in the first cylinder is insufficient to maintain the pressure lifting seat in an upward state. The first limiting block is moved towards and fixed to the mounting base plate. When the pressure lifting seat descends naturally, the first limiting block abuts against the upper surface of the mounting base plate, restricting the first pressure plate and the first pressure plate from continuing to move downward, thus avoiding conflict with other mechanisms.

[0009] The first mounting part is provided with a knob, and the first limiting block is provided with a first adjustment groove. The screw of the knob passes through the first adjustment groove to fix the first limiting block to the first mounting part.

[0010] The aforementioned second cylinder drive rod is fixed to the top of the redundant mounting base. The cylinder body of the second cylinder is connected to a top material lifting plate, the top material lifting plate is connected to a second connecting plate, and the second connecting plate is connected to the first top material plate.

[0011] The aforementioned redundant mounting base has a second limiting block on one side, and the top material lifting plate has a mounting block on one side. A third screw is vertically mounted on the mounting block, and the third screw is located below the second limiting block. When the second cylinder drives the first top material plate to move upward, the screw on the mounting block moves upward, and one end of the screw abuts against the lower surface of the second limiting block, limiting the upward movement distance of the first top material plate.

[0012] Compared with the prior art, the redundancy mechanism of this utility model has a first top plate located below the first pressure plate and the second pressure plate. The first cylinder drives the first pressure plate and the second pressure plate to press down on the main body fabric, and the second cylinder drives the first top plate to lift the main body fabric upward, thus completing the redundancy of the main body fabric.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Figures 1 to 3 The diagram shown is a structural schematic of this utility model.

[0018] The reference numerals in the attached drawings are as follows: redundant mounting base plate 1, fixing plate 2, pressing lifting seat 3, first mounting groove 3a, first mounting part 3b, first slide rail 4, first slider 5, first pressing plate 6, second pressing plate 7, first cylinder 8, first cylinder mounting bracket 9, first cylinder connector 10, first connecting plate 11, first limiting block 12, first adjusting groove 12a, knob 13, redundant mounting base 14, second cylinder 15, first top plate 16, top lifting plate 17, second connecting plate 18, second limiting block 19, mounting block 20, third screw 21.

[0019] like Figure 1 As shown, the redundancy mechanism of a bag-applying machine of this utility model includes a redundancy mounting base plate 1 mounted on the machine frame and a redundancy mounting base 14 mounted below the worktable. A first cylinder 8 is mounted on the redundancy mounting base plate 1, and the first cylinder 8 is connected to a first pressure plate 6 and a second pressure plate 7. A second cylinder 15 is mounted below the redundancy mounting base 14, and the second cylinder 15 is connected to a first top plate 16.

[0020] The first cylinder 8 drives the first pressure plate 6 and the second pressure plate 7 to press down on the main body fabric on the worktable. The second cylinder 15 drives the first top plate 16 to lift the main body fabric upward. The first pressure plate 6, the second pressure plate 7 and the first top plate 16 work together to leave extra material in the middle part of the main body fabric, optimizing the sewing effect of the patch pocket.

[0021] like Figure 2 As shown, one end of the redundant mounting base plate 1 is fixed to the frame. A fixing plate 2 is vertically mounted on the redundant mounting base plate 1. A pressure lifting seat 3 is slidably mounted on the front side of the fixing plate 2. A first slide rail 4 is mounted on the rear side of the pressure lifting seat 3. A first slider 5 that cooperates with the first slide rail 4 is mounted on the front side of the fixing plate 2. The pressure lifting seat 3 can move up and down relative to the fixing plate 2 along the first slide rail 4.

[0022] Below the pressing lifting base 3, there is a first pressing plate 6 and a second pressing plate 7, one end of the first pressing plate 6 and the second pressing plate 7 are respectively connected to the pressing lifting base 3. The bottom of the pressing lifting base 3 is provided with a first mounting groove 3a. One end of the first pressing plate 6 is provided with a first screw, which is inserted into the first mounting groove 3a. One end of the second pressing plate 7 is provided with a second screw, which is inserted into the first mounting groove 3a.

[0023] A first cylinder 8 is provided on the rear side of the fixed plate 2. The cylinder body of the first cylinder 8 is mounted on the fixed plate 2 via a first cylinder mounting bracket 9. The drive rod of the first cylinder 8 is connected to the other end of the first pressure plate 6 and the other end of the second pressure plate 7. The first cylinder 8 drives the first pressure plate 6 and the second pressure plate 7 to move up and down along the first slide rail 4.

[0024] The drive rod of the first cylinder 8 is connected to the first cylinder connector 10, and the first cylinder connector 10 is connected to the first connecting plate 11. The first connecting plate 11 is connected to the other end of the first pressure plate 6 and the other end of the second pressure plate 7. The drive rod of the first cylinder 8 drives the first connecting plate 11 to move up and down through the first cylinder connector 10, and the first connecting plate 11 drives the first pressure plate 6 and the second pressure plate 7 to move up and down.

[0025] A first limiting block 12 is provided on one side of the pressing lifting seat 3, and a first mounting part 3b with an inward recess is provided on one side of the pressing lifting seat 3, into which the first limiting block 12 can be inserted. The first mounting part 3b is provided with a knob 13, and the first limiting block 12 is provided with a first adjusting groove 12a. The screw of the knob 13 passes through the first adjusting groove 12a to fix the first limiting block 12 to the first mounting part 3b.

[0026] The first cylinder 8 is connected to the air source interface. Under normal working conditions, the first limit block 12 is away from the redundant mounting base plate 1, and the first cylinder 8 drives the first pressure plate 6 and the second pressure plate 7 to move up and down normally.

[0027] When the air supply is cut off, the air pressure in the first cylinder 8 is insufficient to maintain the first pressure plate 6 and the second pressure plate 7 in an upward state. The first pressure plate 6 and the second pressure plate 7 naturally fall due to gravity caused by the lack of air supply, which in turn affects the subsequent processing steps.

[0028] Therefore, the knob 13 can be turned to loosen the first limiting block 12, move the first limiting block 12 towards the redundant mounting base 1, and fix it. When the pressure lifting seat 3 descends naturally with the first pressure plate 6 and the second pressure plate 7, the first limiting block 12 abuts against the upper surface of the redundant mounting base 1, restricting the first pressure plate 6 and the first pressure plate 7 from continuing to move downward, thus avoiding conflict with other mechanisms.

[0029] like Figure 3 As shown, the top of the redundant mounting base 14 is fixed to the lower surface of the workbench. A second cylinder 15 is provided below the redundant mounting base 14. The second cylinder 15 is connected to a first top material plate 16, and the second cylinder 15 can drive the first top material plate 16 to move up and down. The drive rod of the second cylinder 15 is fixed to the top of the redundant mounting base 14. The cylinder body of the second cylinder 15 is connected to a top material lifting plate 17. The top material lifting plate 17 is connected to a second connecting plate 18, and the second connecting plate 18 is connected to the first top material plate 16.

[0030] When the drive rod of the second cylinder 15 extends, the cylinder body of the second cylinder 15 moves downward relative to the mounting base 14, and the top material lifting plate 17 moves downward along with the cylinder body of the second cylinder 15, causing the first top material plate 16 to move downward. When the drive rod of the second cylinder 15 retracts, the cylinder body of the second cylinder 15 moves upward relative to the mounting base 14, and the top material lifting plate 17 moves upward along with the cylinder body of the second cylinder 15, causing the first top material plate 16 to move upward.

[0031] A second limiting block 19 is provided on one side of the mounting base 14, and a mounting block 20 is provided on one side of the top material lifting plate 17. A third screw 21 is vertically mounted on the mounting block 20, and the third screw 21 is located below the second limiting block 19. When the second cylinder 15 drives the first top material plate 16 to move upward, the screw on the mounting block 20 moves upward, and one end of the screw abuts against the lower surface of the second limiting block 19, limiting the upward movement distance of the first top material plate 16.

[0032] The first top plate 16 is located directly below the first pressure plate 6 and the second pressure plate 7. The first pressure plate 6 and the second pressure plate 7 cooperate with the first top plate 16. The first cylinder 8 drives the first pressure plate 6 and the second pressure plate 7 to press down on the main body fabric, and the second cylinder 15 drives the first top plate 16 to lift the main body fabric upward, thus completing the positioning of the main body fabric. In addition, for fabrics of different thicknesses, the distance between the first pressure plate 6 and the second pressure plate 7 is adjusted to ensure that the first top plate 16 lifts the main body fabric with sufficient margin.

[0033] The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
