Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a single-step direct-drive motor cutting machine. Background Art

[0002] In the existing field of clothing machinery, there is a widely used device, namely an automatic knife-grinding cutting machine, which is widely used in the cutting of women's clothing, fashion, uniforms, suits and other clothing. It has the advantages of high automation degree, stable operation and high efficiency. In the existing cutting machine, the power part is usually a motor. During the operation of the motor, the cutting knife of the cutting machine can be driven to reciprocate up and down through a transmission mechanism, and the moving cutting knife is used to cut the fabric.

[0003] For example, in the Chinese utility model with the publication number of CN205766424U, the disclosed straight knife cutting machine includes a cloth cutting mechanism. One end of the cloth cutting mechanism is connected with a knife-grinding mechanism, and the other end is connected with a starting mechanism. A column is arranged on the side of the cloth cutting mechanism facing the ground. A base is arranged at the free end of the column. A power source is arranged at the free end of the knife-grinding mechanism. A connecting rod connected to the power source is arranged in the vertical direction at the free end of the knife-grinding mechanism. The power source can drive the connecting rod to slide up and down in the vertical direction at the free end of the knife-grinding mechanism. A presser foot is arranged at one end of the connecting rod close to the base. A detection device with a detection direction facing the base is arranged on the side of the knife-grinding mechanism close to the base, which is used to detect the height of the material placed on the base and send the detected signal to the control device. A control device is arranged on the power source. After receiving the signal sent by the detection device, the control device drives the power source to drive the connecting rod to change the up and down position of the presser foot, so that the presser foot can press the material placed on the base.

[0004] The rack on the connecting rod meshes with the gear on the output shaft of the stepping motor to drive the up and down sliding of the knife-grinding mechanism in the vertical direction. This transmission mechanism is complex and has a high cost, and the structure needs to be further improved. Content of the Utility Model
