Description

Technical Field

[0001] The invention relates to the technical field of tea production, in particular to a rolling cutter for producing tea. Background Art

[0002] Tea is made from the tender buds or new leaves picked from tea trees, and is made through processes such as picking, withering, fermentation, killing, rolling, chopping, drying, and refining. Different teas have different processing requirements. Some teas need to be crushed during the processing to form highly crushed tea leaves. Crushing is usually processed by a rolling cutter, but the existing rolling cutter still has some problems during use, as follows: The existing tea rolling and cutting machine mainly puts the tea leaves into a drum and then uses the internal rotating blade to cut the tea leaves. However, this method is inefficient on the one hand, and the tea leaves cannot be well crushed, which leads to unqualified high-broken tea leaves in the subsequent process. On the other hand, during the crushing process, the juice inside the tea leaves will be released, which leads to high water content in the high-broken tea leaves and is susceptible to mildew and oxidation. The existing rolling and cutting machine cannot dry the tea leaves in the crushing process, and cannot guarantee the subsequent tea production quality. For this reason, we propose a rolling and cutting machine for producing tea leaves. Summary of the invention

The inner tube 6 is compressed, and then the second spring 186 is squeezed, which drives the limit plate 183 to extend inward to block the rotation of the crushing rod 116. In this way, the first spring 115 stores elastic potential energy when the inner ring block 111 continues to rotate. Finally, under the jacking action of the electric push rod 156, the adjusting coil spring 155 moves up, and the restriction on the convex plate 185 is released. Under the elastic force of the second spring 186, the limit plate 183 moves in the opposite direction, and the restriction on the crushing rod 116 is released.

After the crushing rod 116 is blocked, the first spring 115 will store elastic potential energy under the action of the continued rotation of the inner ring block 111. After rotating a corresponding number of circles, the electric push rod 156 at the bottom is started, and the electric push rod 156 pushes the adjusting coil spring 155 upward, so that the convex plate 185 is separated from the adjusting coil spring 155. Under the action of the second spring 186, the convex plate 185 rebounds outward, and at the same time drives the limit plate 183 to contract, thereby releasing the restriction on the crushing rod 116. Under the action of the elastic potential energy stored in the first spring 115, the crushing rod 116 rotates at a high speed to crush the tea leaves; The broken tea leaves will fall to the top of the bottom filter plate 8, those that meet the requirements will enter the collection box 7 for collection, and the rest will slide to the discharge port on the side, where airflow is generated under the rotation of the impeller 4. The airflow is heated by the heating wire 5 and enters between the outer cylinder 1 and the inner cylinder 6, and then blows the tea leaves discharged from the discharge port upward. Driven by the regulating component 15, the dehumidification guide component 17 will also rotate synchronously. When the tea leaves come into contact with the dehumidification component 173, the moisture and evaporated water vapor on the tea leaves will be absorbed by the dehumidification component 173, and then the tea leaves will pass through the discharge slot 172 and the inner slot 19 to re-enter the inner cylinder 6 for crushing until all of them are crushed. During the use of the device, the dehumidification component 173 can be lifted up for replacement.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
