Description

Technical Field

[0001] The utility model belongs to the technical field of industrialized breeding, and particularly relates to a vacuum adsorption blanking cylinder. Background Art

[0002] Silkworm rearing with artificial feed has changed the situation that silkworm rearing must completely rely on mulberry trees for feed, and it can be carried out without being restricted by seasons and natural conditions. It reduces the labor intensity of sericulturists, increases the number of silkworms reared, and increases the economic income. The realization of the artificial feed silkworm rearing technology reduces the difficulty of silkworm rearing mechanization and provides a prerequisite for realizing silkworm rearing mechanization.

[0003] Due to the increasing scale of industrialized breeding, the conveying distance of artificial feed is also getting longer and longer. Usually, a blanking cylinder is used for the conveying of artificial feed. During the conveying process of artificial feed, because the artificial feed is sticky, it is easy to adhere to the inner wall of the blanking cylinder, resulting in waste, and the subsequent cleaning is rather cumbersome.

[0004] To solve the above technical problems, when conveying artificial feed, a thin film is laid on the inner wall of the blanking cylinder and then the artificial feed is conveyed. Since the artificial feed is heated and stirred before conveying, the chimney effect is generated, causing the air inside the blanking cylinder to form a convection with the outside air, making the thin film gather in the center of the blanking cylinder and unable to adhere to the inner wall of the blanking cylinder. As a result, the artificial feed falls smoothly, a large amount of it adheres to the thin film, and even the blanking cylinder is blocked. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above technical problems existing in the prior art, and provide a vacuum adsorption blanking cylinder.
