Problems solved by technology
The traditional up-and-down structure of the fabric uses complex mechanical structures such as cams or connecting rods to make the fabric move up and down. The traditional up-and-down movement of the fabric is rigid. Once a hard mass is adhered to the fabric, it is easy to break the sewing needle. At the same time, the traditional sewing machine needle The transmission structure is relatively complicated, and the rigid transmission method is not convenient for the arrangement of the overall structure of the sewing machine, especially on some equipment that requires automatic sewing. In order to make the sewing machine head easy to move, people usually design the power source such as the motor on the sewing machine head. This makes the machine head volume of the sewing machine larger, making the volume of the equipment larger and the energy efficiency utilization lower

The invention provides a pneumatic needle sewing device. The pneumatic needle sewing device comprises a pneumatic injection head, a sewing needle and a needle receiving module. The pneumatic injection head is provided with a vertical sliding cavity. The sewing needle is arranged in the sliding cavity in a sliding mode. A high-pressure air cavity communicated with the sliding cavity is formed in the upper portion of the pneumatic injection head and connected with a high-pressure air channel through a high-pressure air turning module. Cloth pressing modules are arranged between the pneumatic injection head and the needle receiving module. A cloth material to be sewn horizontally passes through the space between the cloth pressing modules. When the pneumatic needle sewing device is used, the positive and negative alternating high-pressure air channel is led into the high-pressure air cavity through the high-pressure air turning module, and then the sewing needle is purshed to drive a sewing thread to move up and down. The pneumatic needle sewing device conducts driving pneumatically, so the sewing needle has flexibility in the penetrating process and is prevented from being broken, and automatic design and transformation of equipment is facilitated better.
Description
Technical field [0001] The invention belongs to the technical field of sewing equipment, in particular to a pneumatic needle sewing device. Background technique [0002] The sewing machine sews the fabric through the needle with a threading hole in the lower part. The sewing needle moves up and down under the drive of the transmission structure. Fabric is sewn on. The traditional up-and-down structure of the fabric uses complex mechanical structures such as cams or connecting rods to make the fabric move up and down. The traditional up-and-down movement of the fabric is rigid. Once a hard mass is adhered to the fabric, it is easy to break the sewing needle. At the same time, the traditional sewing machine needle The transmission structure is relatively complicated, and the rigid transmission method is not convenient for the arrangement of the overall structure of the sewing machine, especially on some equipment that requires automatic sewing. In order to make the sewing mac...
