Brief analysis of the technological performance and principle of tea mechanical brush_FAQ

You may not know that brushes are also used in tea machinery, which proves that the use of brushes is ubiquitous, and there are two types of machinery used in tea machinery, there are flat circular sieve machines and shakers. Screening machine, what are their technological performance and principle? The technological performance of the flat round sieve machine is to use the operations of sieving, sifting and sifting, and the effect is to separate the length of the bar tea and the size of the round tea. The principle of the brush operation is: when the flat circular sieve machine is operating, the sieve bed makes a circular translational movement with a circular mass point track, and the tea leaves are subjected to the effect of moderate centrifugal inertia force on the sieve surface, and lie flat on the sieve surface for sliding or Tumble movement. Suppose the side length of the screen mesh is a. For bar-shaped tea, the tea with a length greater than 2√2 a has been supported by more than two points, and it is not easy to pass through the screen and become a sieve tea; on the contrary, the length of the tea is less than The tea of u200bu200b2√2 a simply loses its balance during the movement process, and passes through the sieve to become the tea under the sieve. For round tea, the tea leaves with a particle size larger than a cannot easily pass through the sieve and become oversieve tea; on the contrary, the tea leaves with a particle diameter smaller than a can easily pass through the sieve and become undersieve tea. Then reach the purpose of separating the length and size of the tea leaves. The principle of using the brush of the sieve shaker is: during operation, the sieve surface oscillates at a high frequency, and the tea leaves move due to the inertial force caused by the oscillation of the sieve surface. Because this force changes direction at a high frequency along the length of the sieve bed, The tea leaves and the tea leaves, and the tea leaves and the sieve surface collide, forcing the tea leaves to stand upright. Therefore, the sieve surface with different meshes can be used to sieve tea with different grain sizes. The technological performance of the sieve shaker is to separate the bar tea from the thickness and the round tea from the long round, and to remove the tea head, remove the stalks, and make the thickness of the tea greens equal.
