Description

Technical Field

[0001] The invention relates to the technical field of tea rolling machines, in particular to a disc type tea rolling machine. Background Art

[0002] The tea rolling machine is a machine specially used for rolling tea leaves. The friction between the rolling cylinder and the rolling plate is used to squeeze, roll and rub the tea leaves in the rolling cylinder. During the rolling process, the tea leaves are gradually curled into strips under the action of mechanical force, and the appearance becomes tight, uniform and beautiful. It also helps to maintain the integrity and stability of the tea leaves during subsequent processing and storage. During the rolling process, the leaf cells of the tea leaves are squeezed and rubbed and broken, and the tea juice overflows. This process promotes the oxidation reaction between the effective ingredients in the tea leaves and the oxygen in the air, creating conditions for the formation of the unique aroma and taste of tea leaves.

[0003] The movement of tea leaves in the barrel divides the rolling barrel into four action zones: rolling zone, strong pressure zone, downward turning zone and hollow zone. The rolling zone is the main area where the tea leaves are rolled into strips. In this area, the tea leaves are subjected to the reaction force of the rolling barrel and curl forward along the ribs into strips. The strong pressure zone is the main area where the tea leaves are clumped. In this area, the tea leaves are subjected to the reaction force of the rolling disk surface, the kneading force of the ribs and the pressure of the rolling cover on the tea leaves. The strength of the force is the greatest at this time. Under the action of these three forces, the tea leaves are squeezed toward the center of the rolling barrel with the greatest degree of squeezing. In the downward turning zone, the reaction force of the rolling barrel, the reaction force of the rolling disk surface and the kneading force of the ribs on the tea leaves are almost negligible. In this area, the tea leaves have moved to the top of the rolling barrel and rolled downward under the action of inertia and gravity. There is no tea leaves in the hollow zone because the rolling barrel has been rotating all the time, and the tea leaves that fell from the downward turning zone did not arrive there instantly, resulting in a gap.

[0004] However, in the prior art, the tea leaves tumble in the rolling cylinder only by relying on the interaction force between the rolling cylinder and the rolling plate, and the tumbling amplitude of the tea leaves is small. When a large amount of tea leaves are rolled, the tea leaves on the top are not easy to roll down, resulting in uneven rolling of the tea leaves during the rolling process. In order to make the rolling more uniform, the prior art usually increases the rolling time. However, as the rolling time increases, the tea juice is easy to evaporate, which is not conducive to fermentation and reduces the quality of the tea leaves.

[0005] For this reason, a disc type tea leaf rolling machine is proposed. Summary of the invention

[0006] The object of the present invention is to provide a disc-type tea rolling machine. In order to solve the problem of uneven tumbling of tea leaves in a rolling cylinder, a push rod assembly is driven by a rolling barrel assembly to keep the push rod assembly in a rolling zone, and a rotating cam assembly is used to push the push rod assembly to operate, so as to push the tea leaves to the tumbling zone and the rolling zone, thereby increasing the running amplitude of the tea leaves in the rolling cylinder, thereby improving the tumbling effect of the tea leaves and solving the problem of uneven tumbling of the tea leaves in the rolling cylinder.

[0009] In the above scheme, the power component drives the kneading barrel assembly to make circular motion around the kneading plate. When the kneading barrel assembly moves around the inner wall of the kneading plate, the reversing component drives the kneading barrel assembly to rotate. At this time, the push rod assembly rotates together with the kneading barrel assembly, so that the push rod assembly is always in the kneading area and drives the cam assembly to move together.

[0011] In the above scheme, the reverse gear is meshed with the outer gear ring and the inner gear teeth at the same time, so as to drive the inner kneading barrel to rotate in the opposite direction to the direction of its own movement around the kneading plate, so that the push rod assembly is always in the kneading area, and at the same time, the spiral ridges on the inner wall of the lower kneading barrel increase the friction between the tea leaves and the inner wall of the lower kneading barrel, thereby improving the kneading effect.

[0013] In the above scheme, the tea leaves in the rolling and twisting zone are pushed to the top of the tea ball by the oblique thrust of the left push rod, so that the tea leaves at the bottom enter the downward turning zone faster.

[0014] Preferably, the front view cross section of the left push plate is set to be a right-angled trapezoid, and the right-angled side is connected to the right side of the left push rod, the bottom of the left push rod is an inclined plate, and the side view cross section is an inverted triangle.

[0015] In the above scheme, by setting the left push plate as a right-angle trapezoid, the rotation angle of the left push plate is limited, and the pulling back of the top tea leaves is reduced when the left push plate is pushed back.

[0016] Preferably, the right push mechanism includes a right connecting cylinder, a right push rod, a right push plate, a connecting plate, a telescopic rod and a transmission rod, the connecting plate is connected to the right side of the inner wall of the inner kneading barrel, the left side of the connecting plate is connected to the connecting rod 60241, the right connecting cylinder is hinged to the bottom of the connecting rod 60241, the right push rod is connected to the inner wall of the right connecting cylinder, the connecting rod 60241 is connected to the left end of the right push rod, the bottom of the transmission rod passes through the connecting plate to be connected to the cam assembly, and the bottom of the transmission rod passes through the connecting plates and is connected with a compression spring, and the telescopic rod is hinged between the right push rod and the transmission rod.

[0017] In the above scheme, the tea leaves in the strong pressing area are pushed to the kneading area by the right push plate, and when pulled back, the left end of the right connecting cylinder tilts upward under the effect of oblique pulling, thereby pulling the tea leaves in the lower turning area to the trapped area, thereby accelerating the turning speed.

[0018] Preferably, the connection between the right push plate and the right push rod is located below the middle of the right push plate, and the cross-section of the right push plate is set to be a boomerang shape.

[0019] In the above scheme, by making the length of the upper half of the right push plate greater than the lower half, the effect of pulling the tea leaves when pulling back is improved.

[0021] In the above scheme, the left push rod and the right push rod drive the synchronous ring to rotate, so that the internal gear moves and rotates on the annular gear plate, thereby driving the left cam and the right cam to rotate, and the left cam and the right push rod are pushed to move.

[0022] Preferably, the front view cross section of the left cam is set to be an isosceles trapezoid, and the side view cross section is set to be an ellipse, and the inclined surface is perpendicular to the left push rod, and the narrow end of the left cam is connected to the rotating shaft.

[0023] In the above scheme, the front view cross section of the left cam is set to an isosceles trapezoid, and the side view cross section is set to an ellipse, so that the thrust direction of the left cam is parallel to the left push rod, thereby reducing the pushing resistance.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When the pushing component moves upward, the tea leaves in the kneading zone are pushed to the downward turning zone, and the tea leaves in the strong pressure zone are pushed to the kneading zone. When the pushing component moves downward, the tea leaves in the downward turning zone are pulled to the hollow area, thereby accelerating the tumbling speed and amplitude of the tea leaves in the kneading barrel component, thereby making the tea leaves inside the kneading barrel component tumble more evenly, shortening the kneading time, reducing the evaporation of tea juice, and improving the quality of tea leaves.

[0026] 2. By arranging spiral ribs on the inner wall of the inner kneading barrel, the friction of the inner kneading barrel on the internal tea ball is increased during its rotation, thereby improving the kneading effect of the tea leaves. Since the spiral direction is the same as the rotation direction of the inner kneading barrel, the tea leaves below the tea ball are rotated to the top of the tea ball, further improving the tumbling effect.

[0027] 3. By setting the annular edge, the inner kneading barrel is prevented from shifting up and down during movement, and the misalignment with the inner gear teeth is avoided, thereby improving the stability of operation and the quality of kneading. At the same time, it also prevents the tea leaves from entering the meshing area and crushing the tea leaves. The annular edge also seals the gap between the kneading barrel and the kneading plate, thereby reducing the splashing of tea leaves from the kneading plate and avoiding the waste of tea leaves.

The left connecting tube 6011 is connected to the left side of the inner wall of the inner kneading barrel 503. The top of the left connecting tube 6011 is tilted to the right, so that when the left push rod 6012 moves upward, the thrust on the tea leaves is tilted upward, making it easier for the tea leaves to enter the downward turning area. The left push rod 6012 is connected to the inner wall of the left connecting tube 6011, and the outer wall of the left push rod 6012 is connected to a limiting block 60121. The limiting block 601 A return spring 60122 is connected to the bottom of 21, and the bottom of the return spring 60122 is connected to the bottom of the inner wall of the left connecting tube 6011, and the left push rod 6012 is driven to move upward by the return spring 6012. The left push plate 6013 is hinged to the right side of the left push rod 6012, so that when the left push rod 6012 drives the left push plate 6013 to reset, the left push plate 6013 flips upward under the resistance of the tea leaves, thereby reducing the amount of tea leaves pulled back by the left push plate 6013 when it is reset.

[0049] Working principle: In order to make the tea leaves roll more evenly inside the kneading barrel, the push rod assembly 6 is used to push the movement of the tea leaves inside the kneading barrel, thereby accelerating the rolling of the tea leaves inside the kneading barrel and making the tea leaves roll more evenly;

[0050] Specifically, tea leaves are placed inside the kneading barrel assembly 5, and the power assembly 2 drives the upper kneading barrel 501, the lower kneading barrel 502 and the inner kneading barrel 503 to make clockwise circular motion around the kneading plate 4, and the reversing assembly 8 between the annular edge 5021 of the outer wall of the lower kneading barrel 502 and the inner kneading barrel 503 is meshed with the inner gear 401 of the inner wall of the kneading plate 4. Since the outer gear ring 5031 of the outer wall of the inner kneading barrel 503 is also connected to the reversing assembly 8, the inner kneading barrel 503 is indirectly driven to rotate counterclockwise. The push rod assembly 6 is driven to move to drive the cam assembly 7 to move.
