[0002] The silk drawing process is the process of processing silkworm pupae into silk. The existing silk drawing methods are mainly divided into manual reeling and mechanized reeling. Mechanized reeling usually uses a reeling machine to draw silk from silk cocoons, that is, the compressed silk cocoons are fed to the surface of a drum through a licker-in roller, and then the silkworm pupae are drawn by the rotating drum so that the silk covers the surface of the drum. When the silk covers a certain thickness on the drum, the silk is peeled off the drum to form a sheet of silk cotton, thereby completing the silk drawing process of the cocoon.

The partition 9 is located below the first filter 8, and the heating element 11 can be an electric heating block.

[0028] Specifically, Figure 3 and Figure 5As shown, the cutting mechanism 15 includes a fixed plate 151 installed at the top of the wire drawing machine body 1, two symmetrically distributed support plates are installed at the bottom of the fixed plate 151, and a screw rod 152 is rotatably installed between the two support plates, a moving seat 153 is sleeved on the screw rod 152, and a cutting knife 154 is installed at the bottom end of the moving seat 153, and a motor 155 for driving the screw rod 152 to rotate is installed on one side of one of the support plates.

[0029] During the silk-drawing process of silk cocoons, hot water is first added into the soaking barrel 10, and then the silk cocoons are added into the silk-drawing machine body 1 through the feeding hopper 2, so that the silk cocoons fall into the soaking barrel 10 and are soaked. After soaking for a period of time, the partition 9 can be pulled out. At this time, under the action of the first filter 8, the silk cocoons remain on the first filter 8, and the hot water in the soaking barrel 10 is discharged into the silk-drawing machine body 1 and discharged through the drain port at the bottom of the silk-drawing machine body 1.
