Technical Field
The invention relates to a processing device, in particular to a processing device of mulberry leaf and chrysanthemum tea.
Background
Various kinds of substituted tea sold in the market at present are numerous, but most of the substituted tea is prepared by simply mixing concentrated raw materials directly without deep processing, and is simple in package and single in effect. They can only play the roles of clearing heat, refreshing and aiding digestion, and have no obvious effect on the prevention, treatment and health care of human bodies. For example, the mint chrysanthemum tea on the market at present is prepared by simply mixing chrysanthemum and mint leaves together.

the first sheath, the second sheath, the upper linkage screen, the fixed screen, the lower linkage screen and the annular support flat plate are located right above the lower conveying belt, and the width of the lower conveying belt is larger than the inner diameter of the second sheath.
The mulberry leaf powder, the chrysanthemum fluid extract, the honey and the stevioside are uniformly mixed, and the granulated tea obtained by granulation contains a certain amount of water and needs to be dried; in the drying process of the granulated tea, a part of the granulated tea can be adhered to the conveying belt, and a part of the granulated tea can be adhered to form large-granule tea lumps; this not only can influence the normal work of conveyer belt, causes the tea granule homogeneity not good moreover, reduces tea granule quality. The scheme aims at overcoming the defects, improves processing equipment and effectively solves the problems.
On one hand, in the conveying process of the upper conveying belt, a first driving motor of the anti-sticking device drives a cam to rotate, and a compression spring is pre-tightened in a matched mode, so that the upper driving wheel and the upper driven wheel move back and forth; and then the upper conveying belt continuously generates tensioning/shrinking action, so that certain relative displacement and shaking are generated between the granular tea and the upper conveying belt in the process of conveying the granular tea on the upper conveying belt, and the granular tea can be effectively prevented from being adhered to the upper conveying belt.
On the other hand, in the working process of the upper conveying belt, the rotary actuating mechanism drives the first sheath to rotate; when the first sheath rotates, the vertical guide sleeve, the guide rod, the second sheath, the upper linkage screen, the fixed screen and the lower linkage screen are driven to rotate together.
When the granular tea is output from the output end of the upper conveyer belt, the granular tea is in a roughly dry state. After the granular tea is output to the screen of the granule disassembling and screening mechanism from the output end of the upper conveying belt, the granular tea with the granule size meeting the requirement can rapidly pass through the upper linkage screen, the fixed screen and the lower linkage screen to be discharged onto the lower conveying belt; and after the large-particle tea mass formed by bonding a plurality of particles of tea passes through the upper linkage screen, one part of the large-particle tea mass is blocked by the fixed screen, and the other part of the large-particle tea mass passes through the fixed screen and is blocked by the lower linkage screen (the mesh openings of the upper linkage screen are large enough to allow the large-particle tea mass to pass through).
In the process, the upper linkage screen, the fixed screen and the lower linkage screen continuously rotate, so that the granular tea can be prevented from being gathered at a certain part of the screen, and the granular tea can be uniformly distributed to all parts of the screen, and the granular tea with the particle size meeting the requirement can rapidly pass through the upper linkage screen, the fixed screen and the lower linkage screen and fall onto the lower conveying belt;
more importantly, in the rotating process of the first sheath, the second sheath and the guide rod, when a universal wheel or a ball at the lower end of the guide rod passes through the arc-shaped bulge on the annular support flat plate, the guide rod drives the upper linkage screen and the lower linkage screen of the second sheath to move upwards and then move downwards together, and the height of the fixed screen is unchanged in the process; therefore, when the upper linkage screen mesh moves downwards, the distance between the upper linkage screen mesh and the fixed screen mesh is continuously reduced, so that large-particle tea balls on the upper linkage screen mesh are scattered and separated and pass through the fixed screen mesh (wherein part of the granular tea balls pass through the lower linkage screen mesh according to the requirement, and the other part of the granular tea balls cannot pass through the lower linkage screen mesh); in the process that the lower linkage screen mesh moves upwards, the distance between the lower linkage screen mesh and the fixed screen mesh is continuously reduced, so that large-particle tea balls on the lower linkage screen mesh are scattered and separated, pass through the lower linkage screen mesh and fall onto a lower conveying belt; therefore, in the continuous rotating process of the first sheath, the vertical guide sleeve, the guide rod, the second sheath, the upper linkage screen, the fixed screen and the lower linkage screen, the screening of the granular tea and the disassembly of the large granular tea lumps are finished, so that the granular tea is uniform in size and meets the requirements.
The granular tea falling onto the lower conveying belt is output through the lower conveying belt. The granular tea on the lower conveying belt is in a roughly dry state and cannot be bonded with the lower conveying belt, and the granular tea on the lower conveying belt is not bonded with the granular tea, so that the granular tea with uniform granules can be obtained after the granular tea is output by the lower conveying belt.
