DETAILED DESCRIPTION

[0023] like Figure 1As shown, the present invention is a yarn cutting mechanism for a wire drawing machine head, comprising a machine head cover 1, a cutting blade 2 and a transmission member 3. The machine head cover 1 is fixed on the wire drawing machine, the cutting blade 2 is used to cut the yarn, and the transmission member 3 is used to connect the power source and the cutting blade 2 to achieve power transmission. Specifically, the machine head cover 1 is provided with a cutting hole 4, the cutting blade 2 is arranged in the cutting hole 4, and the transmission member 3 is arranged in the machine head cover 1. One end of the transmission member 3 is connected to the power source, and the other end of the transmission member 3 is connected to the cutting blade 2. The cutting blade 2 extends out of the cutting hole 4 and cuts the yarn under the action of the transmission member 3. Through the above arrangement, the yarn cutting at the machine head cover 1 can be achieved, replacing manual yarn cutting, reducing labor costs, and the yarn cutting efficiency is higher, and the safety hazards of manual yarn cutting can be eliminated. The power source is generally a power mechanism with a linear stroke, generally a cylinder or an electric push rod. Similarly, a motor can also be used to realize the movement of the cutting blade 2 through a transmission member 3 in the form of a gear.

[0024] like Figure 2 As shown, as an implementation method, the transmission member 3 includes a blade mounting plate 5 and a connecting rod 6, the connecting rod 6 is slidably connected to the machine head cover 1, the blade mounting plate 5 is movably connected to the machine head cover 1, one end of the connecting rod 6 is connected to the power source, and the other end of the connecting rod 6 is connected to the blade mounting plate 5 and drives the blade mounting plate 5 to move. Through the above arrangement, the connection between the power source and the cutting blade 2 can be achieved, which is convenient for driving the cutting blade 2 to move, thereby cutting the yarn.

[0025] Specifically, the machine head cover 1 is provided with a rotating shaft 7, and the blade mounting plate 5 is provided on the rotating shaft 7 and is rotatably connected to the rotating shaft 7. Through the above arrangement, the blade extends out of the cutting hole 4 in a rotating manner to cut the yarn. Among them, the machine head cover 1 is provided with a mounting hole 8, and the rotating shaft 7 is provided in the mounting hole 8 and is detachably connected to the mounting hole 8. By arranging screws on the outer side of the machine head cover 1 to connect with the rotating shaft 7, the fixing of the rotating shaft 7 is achieved. When the rotating shaft 7 needs to be removed, it is only necessary to remove the screws, which is convenient for disassembly and assembly and high in efficiency. In addition, the mounting hole 8 has a positioning effect, which is convenient for positioning the rotating shaft 7 during installation.
