The convenience of the rotation direction is poor. By placing the cocoons on the first conveyor belt 13, the second motor thereon operates to drive one of the rollers to rotate, and one of the rollers drives the transmission wheel thereon to rotate, the transmission wheel drives the transmission chain to rotate, and the transmission chain drives all the transmission wheels to rotate, that is, all the transmission wheels drive all the rollers to rotate, and all the rollers drive the first conveyor belt 13 to rotate, thereby realizing the rotation of the first conveyor belt 13. The second conveyor belt 14 and the third conveyor belt 15 rotate on the same principle as the first conveyor belt 13; but the driving directions of the three groups of second motors are different, the first conveyor belt 13 rotates clockwise, the second conveyor belt 14 rotates counterclockwise, and the third conveyor belt 15 rotates clockwise;

[0019] The first conveyor belt 13 drives the cocoons to move to the inside of the machine body 2, and the fan 19 operates. The fan 19 inputs cold air into the cavity 16.

During the pressure difference, the vacuum cylinder 3 draws the outside air into the inside of the vacuum cylinder 3 from the vacuum hole 4, that is, the vacuum cylinder 3 generates suction to its periphery;

[0021] When the first conveyor belt 13 drives the cocoons to move to the rightmost end, the cocoons fall from the first conveyor belt 13. In this process, the wet side of the cocoons has a large gravity and will naturally rotate downward. At the same time, the vacuum cylinder 3 absorbs the fallen cocoons. The vacuum cylinder 3 absorbs the side of the cocoons. The cocoons rotate counterclockwise with the vacuum cylinder 3 until the cocoons contact the scraper plate 5. The scraper plate 5 separates the cocoons from the vacuum cylinder 3, and the cocoons fall onto the second conveyor belt 14. At this time, the wet side of the cocoons facing downward is turned 45°, and the wet side of the cocoons stands on the second conveyor belt 14. The wet side of the cocoons can fully contact with the hot air, thereby achieving uniform heating of the cocoons.

This structure can control the rotation direction of the cocoons, making it easier to dry the cocoons evenly, and is conducive to improving the convenience of controlling the rotation direction of the cocoons.

[0023] Working principle: in the process of drying cocoons in the existing cocoon drying machine, the cocoons will fall from the high conveyor belt to an adjacent conveyor belt below, which increases the drying time of the cocoons. However, in the process of falling, the cocoons cannot be controlled in terms of their rotation direction. The wet side of the cocoons has a large gravity and will naturally rotate downward, causing uneven drying of the cocoons and poor convenience in controlling the rotation direction of the cocoons. By placing the cocoons on the first conveyor belt 13, the second motor thereon is operated to drive one of the rollers to rotate, one of the rollers drives the transmission wheel thereon to rotate, the transmission wheel drives the transmission chain to rotate, and the transmission chain drives all the transmission wheels to rotate, that is, all the transmission wheels drive all the rollers to rotate, and all The roller drives the first conveyor belt 13 to rotate, realizing the rotation of the first conveyor belt 13. The second conveyor belt 14 and the third conveyor belt 15 rotate in the same principle as the first conveyor belt 13; but the driving directions of the three sets of second motors are different, the first conveyor belt 13 rotates clockwise, the second conveyor belt 14 rotates counterclockwise, and the third conveyor belt 15 rotates clockwise; the first conveyor belt 13 drives the cocoons to move to the inside of the machine body 2, and the fan 19 operates, and the fan 19 inputs cold air into the cavity 16. The cold air is heated to hot air after encountering the heating plate 17, and the hot air is discharged from the air outlet 18, so that the air inside the machine body 2 is hot air, and the cocoons on the first conveyor belt 13 are continuously heated by the hot air, and the moisture gradually evaporates, realizing The drying process of the silk cocoon is realized; the first motor 10 is operated to drive the second gear 11 to rotate, the second gear 11 pushes the first gear 9 to rotate, the first gear 9 drives the first air duct 6 to rotate, the first air duct 6 drives the vacuum cylinder 3 to rotate counterclockwise, and at the same time the vacuum pump 8 is operated, the inside of the vacuum cylinder 3 is evacuated to a vacuum, and there is a pressure difference with the outside world. During the pressure difference process, the vacuum cylinder 3 draws outside air into the vacuum cylinder 3 from the vacuum hole 4, that is, the vacuum cylinder 3 generates suction to its periphery; when the first conveyor belt 13 drives the silk cocoon to move to the rightmost end, the silk cocoon falls from the first conveyor belt 13. In this process, the wet side of the silk cocoon itself has a large gravity and will naturally rotate downward. At the same time, the vacuum cylinder 3 has a large pressure on the falling silk cocoon. The cocoons are adsorbed, the vacuum cylinder 3 adsorbs the side of the cocoons, and the cocoons rotate counterclockwise with the vacuum cylinder 3 until the cocoons contact the scraper plate 5. The scraper plate 5 separates the cocoons from the vacuum cylinder 3, and the cocoons fall onto the second conveyor belt 14. At this time, the wet side of the cocoons facing downward is turned 45°, and the wet side of the cocoons stands on the second conveyor belt 14. The wet side of the cocoons can be fully in contact with the hot air, thereby achieving uniform heating of the cocoons; then the cocoons fall onto the third conveyor belt 15, and the third conveyor belt 15 rotates clockwise to transport the cocoons out of the machine body 2. This structure can control the rotation direction of the cocoons, facilitate the uniform drying of the cocoons, and help improve the convenience of controlling the rotation direction of the cocoons.
