Description

Technical Field

[0001] This utility model belongs to the field of bag-applying machine technology, specifically a redundant positioning mechanism for bag-applying machines. 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 needs to be pre-stitched. Currently, the top plate in the pre-stitching device can lift the middle part of the body fabric by a certain amount of pre-stitching. When the pressing mechanism presses down on the body fabric, the body fabric will unfold outward, resulting in less pre-stitching in the middle part of the body fabric, which affects the sewing effect of the pocket opening. Summary of the Invention

[0004] This utility model addresses the aforementioned technical problems by providing a redundant positioning mechanism for a bag-sealing machine. This mechanism allows for a larger amount of fabric to be left over, preventing the amount of fabric from being reduced during the feeding process and optimizing the sewing effect of the bag opening.

[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 bag-applying machine, including a first pressing plate, a first supporting plate, and a supporting worktable. The first pressing plate is connected to a first cylinder, the cylinder body of the first cylinder is mounted on a first movable plate, the first movable plate is connected to a second cylinder, and the cylinder body of the second cylinder is mounted on a first mounting plate. The first supporting plate is mounted on the front side of the supporting worktable, a second movable plate is provided below the supporting worktable, a third cylinder is provided on the second movable plate, and the drive rod of the third cylinder is connected to the supporting plate worktable.

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

[0007] The first pressure plate is connected to a first connecting block, which is slidably mounted on the first moving plate via a first guide rail. The drive rod of the first cylinder is connected to the first connecting block.

[0008] The first movable plate is slidably mounted on the first mounting plate via the second guide rail, and the drive rod of the second cylinder is connected to the first movable plate via the second connecting block.

[0009] The above-mentioned material handling workbench is provided with a first connecting plate and a second connecting plate at both ends. One end of the second moving plate is connected to the first connecting plate, and the other end of the second moving plate is connected to the second connecting plate.

[0010] The second movable plate is provided with a third connecting plate and a fourth connecting plate at its two ends. The third connecting plate is slidably mounted on the first connecting plate via a third guide rail, and the fourth connecting plate is slidably mounted on the second connecting plate via a fourth guide rail.

[0011] Compared with the prior art, the present invention provides a redundant positioning mechanism for a bag-sealing machine. The second cylinder drives the first pressure plate to move above the first support plate. The first cylinder drives the first pressure plate to press down on the main body fabric. The third cylinder drives the support table to move down. The support table drives the first support plate and the first pressure plate to clamp the main body fabric, causing the middle part of the main body fabric to fold down to create redundant space, thereby optimizing the sewing effect of the bag opening.
