Description

Technical Field

[0001] The utility model relates to the technical field of kangaroo bag patch pocket machines, in particular to a kangaroo bag patch pocket machine. Background Art

[0002] Taking a sweatshirt as an example, its pocket is arranged in the front of the body, and the large pocket in the front of the sweatshirt is called a kangaroo bag in the industry. The folding and patching operations of the kangaroo bag are usually carried out by an automatic sewing machine.

[0003] For example, CN 111826820 A discloses a kangaroo bag sewing device, which includes a workbench assembly and a sewing assembly. The workbench assembly includes a frame and a workbench board, and the workbench board is horizontally and fixedly arranged on the frame. The sewing assembly is arranged on the right part of the frame, and it also includes a hemming assembly, a hemming driving device, a pocket board assembly, a pocket board driving device, a pressing frame device and a pressing frame driving device. The hemming assembly cooperates with the pocket board assembly to hem the pocket fabric. The hemming driving device drives the hemming assembly to move up and down, and the pocket board driving device drives the pocket board assembly to move up and down, forward and backward. The pressing frame device is used to send the hemmed pocket fabric and the body fabric to the sewing assembly for sewing, and the pressing frame driving device drives the pressing frame device to move up and down, forward and backward, left and right.

[0004] Considering improving the sewing accuracy, some sewing machines are provided with laser displacement sensors, but the positions of their laser displacement sensors are fixed, which is not conducive to further improving the accuracy. For example, CN 212206118 U discloses a bone position detection component and a sewing machine. The bone position detection component includes a main bracket, a laser displacement sensor and a presser foot. The laser displacement sensor is installed on the main bracket. The presser foot is an elastic sheet, and the presser foot is installed on the main bracket through a lifting component. The presser foot includes a pressing plate, a deformation gain part and a first installation part. The first installation part is connected to the pressing plate, the pressing plate is connected to the deformation gain part, and an irradiation surface corresponding to the laser displacement sensor is provided on the upper side of the deformation gain part. When the presser foot descends until it presses the fabric, if the fabric has a bone position, the pressing plate presses the bone position. Taking the installation position of the first installation part and the lifting component as a fulcrum, the presser foot deforms, and the deformation gain part of the presser foot amplifies the height of the bone position in the fabric. The laser displacement sensor emits laser to the deformation gain part, thereby increasing the recognition rate of the laser displacement sensor for the bone position.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Utility Model
