Description

Technical Field

[0001] The utility model relates to the technical field of clothing machinery, and particularly relates to an adjusting mechanism for a hemming device of a patch pocket machine. Background Art

[0002] The main difference between a semi-automatic patch pocket machine and an automatic patch pocket machine lies in the application of its ironing-free hemming technology. For a semi-automatic patch pocket machine, an electric heating steam hemming machine needs to be set beside the machine. The hemmed pocket mouth is placed on the feeding part of the patch pocket machine for transmission and sewing. This not only has a high cost but also low efficiency. The automatic patch pocket machine directly performs cold hemming of the bag shape without heating through a hemming device: that is, a piece of bag piece is placed on a bag shape template. The folding knives on the folding bag frame of the hemming device fold the two sides, the front part of the bag shape, and the two corners at the root of the bag piece. At this time, the folding bag frame and the bag shape template have a simultaneous downward movement to press the folded bag shape on the workbench surface. After the folding knives of the folding bag frame retract and withdraw from the working area, the feeding pressing plate or the receiving pressing plate moves downward above the bag shape template to press the folded pocket. Finally, the bag shape template makes a retracting movement, and at the same time, the whole folding bag mechanism rises and resets to end the bag folding process. Then, the folded pocket fabric and the body fabric are sent to the sewing assembly through a corresponding feeding device for sewing.

[0003] In the early automatic patch pocket machines, the upper pressing plate of the hemming device usually only corresponded to the shape of the sewn pocket and could only correspond to one type of bag shape. If the shape or size of the bag shape changed, it was necessary to replace the folding knives and the upper pressing plate of the hemming device to adapt to the new bag shape, with poor compatibility, resulting in an increase in production and processing costs. Especially for the patch pocket machine for sewing high-grade clothing, its hemming device is also equipped with a miter hemming device. Different sizes of pockets require adjusting the miter hemming device, and the debugging is time-consuming, resulting in a reduction in production efficiency.

[0004] Later, some pocket-sticking machines with adjustable folding knife positions appeared. For example, the Chinese utility model patent with application number 202023045164.6 (authorization announcement number CN214300672U) disclosed "A folding device for a fully automatic pocket-sticking machine", which includes a folding device mounting frame, a front quick-loading seat, a left quick-loading seat, a right quick-loading seat, a front folding knife drive device, a left folding knife drive device, a right folding knife drive device, an upper pressure plate assembly and a folding knife assembly. The folding knife assembly includes a front folding knife, a left folding knife and a right folding knife. An upper electromagnet is fixedly installed in the middle of the folding device mounting frame. The front folding knife driving device drives the front quick-loading seat to move. The front folding knife is fixedly set on the front quick-loading seat by quick-loading. The left folding knife driving device drives the left quick-loading seat to move. The left folding knife is fixedly set on the left quick-loading seat by quick-loading. The right folding knife driving device drives the right quick-loading seat to move. The right folding knife is fixedly set on the right quick-loading seat by quick-loading. The lower side of the upper pressing plate of the upper pressing plate assembly is bonded with a pressing plate plate made of elastic material to adapt to different pocket shapes. There is no need to replace the upper pressing plate when the bag shape is changed, and the adaptability is strong.

[0005] However, this type of folding device also has problems. Since the movement of the corner folding device here is driven by a cylinder, due to the limitations of the cylinder drive, the adjustment method of the corner folding device is still achieved by the coordinated limit of the positioning plate and the limit block. Therefore, each time it is adjusted, the screws must be loosened, the limit block must be moved to the correct position and then fixed on the positioning plate. The whole adjustment process is rather cumbersome, and errors may even occur after the adjustment. Moreover, the next time a bag shape that has been processed before is encountered, repeated adjustments can only be performed, which increases the workload.

[0006] Therefore, how to provide a folding device adjustment mechanism that can quickly complete the position adjustment of the corner folding device without setting a positioning plate and a limit block, and can also make each adjustment remembered to avoid repetitive work, is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide an adjustment mechanism for the folding device of a pocket pasting machine, which is more convenient to adjust and can quickly complete the position adjustment of the corner folding device without setting a positioning plate and a limit block, in response to the above technical status quo.

[0008] The technical solution adopted by the present utility model to solve the above technical problems is as follows: The adjusting mechanism of the hemming device of the patch pocket machine includes a folding knife seat, a left bevel hemming device arranged on the left side of the folding knife seat, and a right bevel hemming device arranged on the right side of the folding knife seat.

A first rack extending towards the right and meshing with the gear is arranged on the left bevel hemming device. A second rack extending towards the left and meshing with the gear is arranged on the right bevel hemming device. Under the drive of the motor, the distance between the left bevel hemming device and the right bevel hemming device becomes larger or smaller through the synchronous transmission of the gear, the first rack, and the second rack.

[0009] In order to enable the gear to better drive the first rack and the second rack to move synchronously in opposite directions, preferably, the right end of the first rack extends horizontally to the right side of the folding knife seat, the left end of the second rack extends horizontally to the left side of the folding knife seat, the first rack and the second rack are spaced apart in the front-rear direction, and the gear is arranged within the space and meshes with the first rack and the second rack respectively;

[0010] When the gear rotates counterclockwise, it can synchronously drive the first rack and the second rack to move in opposite directions, so that the distance between the left bevel hemming device and the right bevel hemming device becomes larger. When the gear rotates clockwise, it can synchronously drive the first rack and the second rack to move in opposite directions, so that the distance between the left bevel hemming device and the right bevel hemming device becomes smaller.

[0011] In order to enable the first rack and the second rack to move more smoothly and smoothly during the back-and-forth movement, preferably, a first guide sleeve for the first rack to pass through horizontally and slide back and forth and a second guide sleeve for the second rack to pass through horizontally and slide back and forth are arranged on the folding knife seat.

The two guide rods horizontally pass through the left and right cavity walls of the installation cavity and are exposed at the left and right sides of the folding knife seat. Two fixing sleeves for fixing the guide rods are sleeved on each of the two guide rods. When the guide rods and the fixing sleeves are in a locked state, the two fixing sleeves on each guide rod respectively abut against the inner sides of the left and right cavity walls, so that the guide rods are horizontally limited on the folding knife seat.

[0015] To better install the motor and the gear on the folding knife seat, preferably, an installation plate is arranged in the installation cavity. The installation plate is installed on the two guide rods. The motor is installed at the bottom of the installation plate. A through hole is further formed in the installation plate for the output shaft of the motor to pass through from bottom to top. The gear is connected to the output shaft of the motor and is located above the installation plate.

[0016] To better optimize the overall structure of the left bevel angle hemming device and the right bevel angle hemming device, so that the first rack and the second rack can better drive the left bevel angle hemming device and the right bevel angle hemming device to move respectively, preferably, the left bevel angle hemming device includes a left adjusting seat, a left bevel angle driving member and a left bevel angle folding knife which are connected in sequence from top to bottom.
