Description

Technical Field

[0001] This utility model belongs to the field of pocket sewing machine technology, specifically a redundancy mechanism for a pocket sewing 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 sewing, the body fabric needs to be allowed for deformation due to washing. Therefore, the body fabric needs to be prepared before attaching the bag. Existing preparation mechanisms usually lift the middle part of the body fabric upwards by a certain amount. When the pressing mechanism presses down on the body fabric, the body fabric will spread outwards, resulting in less excess fabric and affecting the sewing effect of the bag opening. Summary of the Invention

[0004] This utility model addresses the aforementioned technical problems by providing a redundant positioning mechanism for a pocket sewing machine. Before attaching the pocket, the main body fabric is pressed down to leave a redundant amount, which is not easily eliminated in subsequent operations, resulting in a more stable pocket sewing effect.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a redundant positioning mechanism for a pocket sewing machine, including a redundant positioning pressure bar and a material support plate disposed on the machine frame, characterized in that: the machine frame is provided with a first lifting cylinder for driving the redundant positioning pressure bar to rise and fall and a rodless cylinder for driving the redundant positioning pressure bar to move back and forth; the machine frame is provided with a second lifting cylinder for driving the material support plate to rise and fall; the front end of the material support plate is provided with an extension portion that cooperates with the redundant positioning pressure bar.

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

[0007] The frame is equipped with a redundant position mounting base, and the rodless cylinder is mounted on the redundant position mounting base. The driving component of the rodless cylinder is connected to the cylinder body of the first lifting cylinder, and the driving rod of the first lifting cylinder is connected to the redundant position pressing bar.

[0008] The aforementioned rodless cylinder has a first connecting plate on its drive rod, and the first lifting cylinder is connected to the first connecting plate via a first cylinder mounting plate; a horizontally arranged first slide rail is provided on one side of the redundant mounting seat, and a first slider is provided on the first slide rail, which is connected to the first connecting plate.

[0009] The material support plate is equipped with a second lifting cylinder at each end. The second lifting cylinder is fixed to the frame by a second cylinder mounting plate, and the drive rod of the second lifting cylinder is connected to the material support plate.

[0010] The aforementioned material support plate has a suction plate at its front end for adsorbing the main body fabric, and the suction plate is connected to a suction lifting cylinder; the frame has a mounting plate below the suction plate, and a vertically arranged second slide rail is provided on the front side of the mounting plate. A second slider is provided on the second slide rail, and the second slider is connected to the suction plate through a second connecting plate.

[0011] There are two sets of suction plates, located on both sides of the extension. The two sets of suction plates are connected by a suction connecting plate. The suction lifting cylinder is fixedly installed on the front side of the mounting plate, and the drive rod of the suction lifting cylinder is connected to the suction connecting plate.

[0012] The rear of the aforementioned material support plate is provided with a clearance groove for the redundant pressure bar to descend and pass through.

[0013] Compared with the prior art, the redundant positioning mechanism of this utility model allows the redundant positioning pressure strip to move forward to above the extension of the support plate. The first and second lifting cylinders simultaneously drive the redundant positioning pressure strip and the support plate to move downward. The redundant positioning pressure strip and the support plate fold the middle part of the body fabric downward to create redundant material. The folded redundant material is not easily offset in subsequent operations, resulting in a more stable pocket sewing effect. Attached Figure Description

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Figures 1 to 3 The diagram shown is a structural schematic of this utility model.

[0019] The reference numerals in the attached drawings are as follows: redundant pressure bar 1, material support plate 2, extension part 2a, clearance groove 2b, first lifting cylinder 3, rodless cylinder 4, second lifting cylinder 5, suction plate 6, suction lifting cylinder 7, redundant mounting seat 8, first connecting plate 9, first cylinder mounting plate 10, first slide rail 11, first slider 12, second cylinder mounting plate 13, mounting plate 14, second slide rail 15, second slider 16, second connecting plate 17, suction connecting plate 18.

[0020] The redundant positioning mechanism of this utility model includes a redundant positioning pressure bar 1 and a material support plate 2 mounted on a frame. Before redundant positioning begins, the material support plate 2 is flush with the worktable. The redundant positioning pressure bar 1 is connected to a first lifting cylinder 3 and a rodless cylinder 4. The material support plate 2 is connected to a second lifting cylinder 5. The front end of the material support plate 2 has an extension 2a that cooperates with the redundant positioning pressure bar 1 for redundant positioning, and the rear end of the material support plate 2 has a clearance groove 2b for the redundant positioning pressure bar 1 to pass through. The front end of the material support plate 2 is provided with a suction plate 6 for adsorbing the main body fabric, and the suction plate 6 is connected to a suction lifting cylinder 7.

[0021] The frame is equipped with a redundant position mounting base 8, and a rodless cylinder 4 is mounted on the redundant position mounting base 8. The drive component of the rodless cylinder 4 is connected to the first lifting cylinder 3, and the drive rod of the first lifting cylinder 3 is connected to the redundant position pressure bar 1. The rodless cylinder 4 can drive the redundant position pressure bar 1 to move back and forth, and the first lifting cylinder 3 can drive the redundant position pressure bar 1 to move up and down. In the initial state, the rodless cylinder 4 drives the redundant position pressure bar 1 to be located behind the material support plate 2, and the drive rod of the first lifting cylinder 3 is in the retracted state, so that the redundant position pressure bar 1 is located below the worktable to avoid conflict with other mechanisms.

[0022] The rodless cylinder 4 has a first connecting plate 9 on its drive rod, and the first lifting cylinder 3 is connected to the first connecting plate 9 via a first cylinder mounting plate 10. A horizontally arranged first slide rail 11 is provided on one side of the redundant mounting base 8, and a first slider 12 is provided on the first slide rail 11. The first slider 12 is connected to the first connecting plate 9, and the rodless cylinder 4 can drive the redundant pressing bar 1 to move back and forth along the first slide rail 11.

[0023] The material support plate 2 is equipped with a second lifting cylinder 5 at each end. The second lifting cylinder 5 is fixed on the frame through the second cylinder mounting plate 13. The drive rod of the second lifting cylinder 5 is connected to the material support plate 2. The second lifting cylinder 5 can drive the material support plate 2 to move up and down.

[0024] In the initial state, the drive rod of the second lifting cylinder 5 is extended, making the material support plate 2 flush with the worktable. When the first lifting cylinder 3 drives the redundant pressure bar 1 to rise, the height of the redundant pressure bar 1 is higher than that of the material support plate 2, and the redundant pressure bar 1 can move horizontally onto the main body fabric to press the material down. The first lifting cylinder 3 and the second lifting cylinder 5 can simultaneously drive the redundant pressure bar 1 and the material support plate 2 to descend, causing the fabric to fold down to form a redundant position.

[0025] Below the suction plate 6 is a mounting plate 14. A vertically arranged second slide rail 15 is provided on the front side of the mounting plate 14. A second slider 16 is provided on the second slide rail 15. The second slider 16 is connected to the suction plate 6 through a second connecting plate 17. The suction plate 6 can move up and down along the second slide rail 15.

[0026] Two sets of suction plates 6 are provided at the front end of the material support plate 2. The two sets of suction plates 6 are located on both sides of the extension 2a and are connected by a suction connecting plate 18. A suction lifting cylinder 7 is fixedly installed on the front side of the mounting plate 14, and the drive rod of the suction lifting cylinder 7 is connected to the suction connecting plate 18. The suction lifting cylinder 7 can drive the suction plates 6 to move up and down. In the standby state, the suction lifting cylinder 7 drives the suction plates 6 to be flush with the worktable, and the negative pressure generated by the suction plates 6 can adsorb and fix the main body of the fabric.

[0027] The main body fabric is placed on the support plate 2. When a fold is needed, the support plate 2 and the folding pressure strip 1 work together to fold the middle part of the main body fabric downwards to create extra fabric, optimizing the sewing effect of the bag opening. The first lifting cylinder 3 moves the folding pressure strip 1 upwards until it is higher than the main body fabric on the support plate 2. Then, the rodless cylinder 4 moves the folding pressure strip 1 forward until it is above the extension 2a. The second lifting cylinder 5 moves the support plate 2 downwards relative to the worktable, while the first lifting cylinder 3 moves the folding pressure strip 1 downwards. With the cooperation of the support plate 2 and the folding pressure strip 1, the middle part of the main body fabric extends downwards, achieving the folding of the main body.

[0028] During the redundancy process, the specific redundancy amount can be adjusted according to the mutual movement of the redundancy pressure bar 1 and the support plate 2, specifically by adjusting the drive stroke of the first lifting cylinder 3 or the second lifting cylinder 5. Furthermore, compared to the previous upward redundancy, the downward redundancy of the redundancy lifting plate allows for more precise control of the redundancy amount, and the redundancy size is more controllable and stable.

[0029] 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.
