However, those of ordinary skill in the art will understand that in various embodiments of the present invention, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a head of a cutting machine. As shown in fig. 1 and 2, the head of the cutting machine includes a cutter mechanism 1, a frame 2, a fixing frame 3 slidably provided on the frame 2 with respect to a table surface of the cutting machine, a driving device 4 provided on the frame 2, a pulley mechanism 5 connected with the driving device 4, a crank link mechanism 6 rotatably provided on the fixing frame 3 and connected with the pulley mechanism 5, and the crank link mechanism 6 is also hinged with the cutter mechanism 1. The driving device 4 is used for driving the belt wheel mechanism 5 to drive, the belt wheel mechanism 5 is used for driving the crank link mechanism 6 to rotate after being driven, and the crank link mechanism 6 is used for driving the cutter mechanism 1 to reciprocate up and down relative to the table top after rotating. The crank link mechanism 6 is also used for driving the belt wheel mechanism 5 to swing relative to the table top by taking the joint of the belt wheel mechanism 5 and the driving device 4 as a pivot point when the fixed frame 3 slides relative to the table top.
It is clear from the above that, since the head of the cutting machine is composed of the cutter mechanism 1, the frame 2, the fixing frame 3, the driving device 4, the pulley mechanism 5 and the crank link mechanism 6, and the fixing frame 3 is slidably disposed on the frame 2 relative to the table top of the cutting machine, while the driving device is fixed on the frame 2, and the crank link mechanism is rotatably disposed on the frame 2 and hinged with the cutter mechanism 6, in addition, since the driving device 4 is connected with the crank link mechanism 6 through the pulley mechanism 5, during the cutting process, the driving device 4 can drive the crank link mechanism 6 to rotate through driving the pulley mechanism 5, and the cutter mechanism can realize up-and-down reciprocating motion relative to the table top under the rotation of the crank link mechanism 6, thereby realizing the cutting of fabrics. Because the driving device 4 is fixed on the frame 2 all the time in the whole cutting process, the up-and-down reciprocating motion of the cutter mechanism does not influence the driving device. In addition, when the fixing frame 3 slides relative to the table top, the crank connecting rod mechanism 6 can be utilized to drive the belt wheel mechanism 5 to swing relative to the table top by taking the joint of the belt wheel mechanism and the driving device 4 as a pivot point, so that a worker can not influence the driving device 4 when adjusting the cutting depth of the cutting knife mechanism, the stability and the reliability of the driving device 4 during working can be greatly improved, the cutting precision of the machine head is further improved, and the fabric is cut at a high speed.
