[0020] S1, adding silkworm cocoons to the feeding rack, then placing the collecting boxes on the bottom side of the two guide racks, and finally starting the motor;

[0021] S2, silkworm cocoon screening, the output shaft end of the motor drives the first reciprocating screw to rotate, and the connecting frame to which the first reciprocating screw is threadedly connected moves along the first sliding column, so that the push plate on one side of the connecting frame moves back and forth on the top of the screen, and the moving speed of the push plate is 0.1-0.2m / s. The silkworm cocoons with smaller sizes will pass through the screen under the push of the push plate and be stored inside the storage cavity. The silkworm cocoons that meet the required size will be blocked on the top of the screen. At this time, the push plate pushes the silkworm cocoons that meet the size to the side of the guide frame and falls on the inside of the collection box;

[0024] S5. Liquid discharge. When high-temperature steam is used to cook the cocoons, part of the steam will be liquefied. At this time, the liquefied water is collected at the bottom of the tank through the drainage holes of the partition. The valve on the upper side of the drainage pipe is opened to discharge the collected liquid. At the same time, the buckle connecting the first cover plate and the box body is opened to take out the cooked cocoons.

[0025] Compared with the prior art, the present invention adopts the above technical solution and has the following technical effects:

[0026] 1. By using one motor as the power source for the pushing component and the feeding component, the structure of the entire equipment can be greatly simplified. Compared with multiple motors driving different components separately, a single motor drives multiple components to move through a transmission device, reducing the number of motors, reducing the complexity of the equipment and reducing the manufacturing cost.

[0027] Second, the first reciprocating screw is driven to rotate by the output shaft end of the motor, and the connecting frame to which the first reciprocating screw is threadedly connected moves along the first sliding column, and the push plate on one side of the connecting frame reciprocates on the top of the screen. The smaller cocoons will pass through the screen under the push of the push plate, and the cocoons that meet the required size will be blocked on the top of the screen. At this time, the push plate pushes the cocoons that meet the size to the side of the guide rack and falls on the inner side of the collection box. Through the cooperation of the screen and the guide rack, the cocoons that meet the requirements can be collected into the collection box respectively, and the cocoons that meet the requirements of different sizes can be efficiently separated, thereby improving the accuracy of screening.

[0028] 3. The fixed plate connected to the outer thread of the second reciprocating screw is driven by the pulley to reciprocate along the second sliding column. When the first through hole and the second through hole are in a connected state, the cocoons pass through the first through hole and the second through hole and enter the top of the screen. At this time, intermittent feeding of the cocoons is realized to avoid blockage caused by excessive cocoon feeding, and the feeding speed of the cocoons is controlled, which effectively avoids the problem of screen blockage caused by excessive cocoon feeding. It can ensure that the screen always maintains a high working efficiency, and the distribution of cocoons on the screen is more even, so that the push plate can more effectively push the cocoons for screening, thereby improving the overall screening efficiency.

[0029] Fourth, the gas inside the tank is extracted through a pipe connected to the bottom of the tank through a vacuum pump. At this time, the steam generated by the steam generator enters the inner side of the tank. With the guidance of the vacuum pump, the steam heats the cocoons from top to bottom and from bottom to top, and the cycle repeats until the cooking process is completed. Negative pressure cooking allows the steam to be evenly distributed in the tank, avoiding the problems of local overheating or uneven temperature that may occur in traditional cooking methods. Negative pressure cooking allows the steam to be evenly distributed in the main tank, and the cocoons are evenly heated during the cooking process. The sericin inside can be more fully dissolved and softened, which is beneficial to the subsequent reeling operation, ensuring that the cocoons are evenly heated and cooked to a consistent degree, thereby improving the reeling quality.
