Description

Technical Field

[0001] The utility model relates to the technical field of tea rolling equipment, in particular to a tea rolling mechanism. Background Art

[0002] Rolling is the initial shaping process of oolong tea. It forms its tight and curved appearance and also affects the improvement of internal quality. Rolling can roll the tea leaves tightly, reduce the volume, lay a good foundation for frying and drying into strips, and appropriately destroy the leaf tissue and transform the material.

[0003] The rolling machine is generally equipped with a frame, a rolling plate, a rolling barrel, a crank mechanism, a pressure mechanism, and a motor. The motor and the crank mechanism drive the rolling barrel to move. During the movement, the tea leaves in the rolling barrel can move with the rolling barrel. Since the movement is restricted by the pressure mechanism, the rolling operation of the tea leaves is achieved. The guide strips on the surface of the rolling plate keep the tea leaves in a polymerized state during the rolling process.

[0004] However, in actual use, the existing tea rolling machines of this type are in a state of aggregation during the rolling process, and the essence of the tea rolling machine is that the pressure mechanism drives the tea leaves to move in the rolling plate. During the movement, the tea leaves on the periphery are always on the periphery, and the tea leaves wrapped in the middle are always in the middle. Therefore, during the rolling process, the tea leaves at different positions are subjected to different forces, which leads to the problem of different rolling degrees of the tea leaves at different positions. Therefore, a tea rolling mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0005] Based on the above description, the utility model provides a tea rolling mechanism to solve the problem of inconsistent rolling effects of existing tea rolling machines.

[0013] Furthermore, an inclined conveying pipe is provided at the bottom end of the feed funnel, a vertical pipe is provided at one end of the inclined conveying pipe, and an inclined discharge pipe is provided on the outer surface of the vertical pipe.

Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein.

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0027] See also Figure 1 , a tea rolling mechanism, comprising:

[0028] A kneading machine body 1, wherein the kneading machine body 1 comprises a disc frame and a main body, wherein the disc frame is arranged at the top of the main body;

[0029] A crank mechanism 2, which is arranged on the top of the kneading machine body 1 through a connecting shaft;

[0030] A kneading barrel 3, which is arranged between the crank mechanisms 2 via a hinge shaft;

[0031] A pressurizing mechanism 4, which is disposed on the surface of the kneading barrel 3 and extends to the interior of the kneading barrel 3;

[0032] Based on the above, the kneading machine body 1, the curved arm mechanism 2, the kneading barrel 3, the pressure mechanism 4 and the kneading plate 5 constitute a complete tea kneading machine, which has the function of kneading. The above structures are all existing technologies, so their specific structures and working principles are not described here.

[0033] like Figure 2 and Figure 3 As shown, the kneading plate 5 is arranged between the kneading machine body 1 and the kneading barrel 3, and is interconnected with the kneading machine body 1;

[0034] The kneading plate 5 includes a plate body 51, which is arranged inside the plate frame. The upper surface of the plate body 51 is provided with a guide bar 53 and a material leakage hole 52, wherein the guide bar 53 is an arc-shaped bar and is distributed in an annular shape with equal spacing. The material leakage hole 52 is a rectangular through hole and is arranged at the center of the plate body 51. The material leakage hole 52 is distributed in an annular shape with equal spacing.

[0035] Based on the above, the guide strips 53 on the surface of the kneading plate 5 play the role of gathering the tea leaves. When the tea leaves move with the kneading barrel 3, the tea leaves are guided by the guide strips 53, so that the tea leaves can always remain in a gathered state. The setting of the leakage holes 52 allows the tea leaves to fall into the inside of the return pipe 6 during the kneading process.

[0036] like Figure 1 , Figure 2 as well as Figure 4 As shown, the material return mechanism includes a material return pipe 6, a servo motor 7 and an auger shaft 8, and is interconnected with the lower surface of the kneading machine body 1;

[0037] The return pipe 6 includes a feed hopper 61, which is arranged at the bottom end of the disc rack and is communicated with the leakage hole 52. An inclined conveying pipe 62 is arranged at the bottom end of the feed hopper 61, and a vertical pipe 63 is arranged at one end of the inclined conveying pipe 62. An inclined discharge pipe 64 is arranged on the outer surface of the vertical pipe 63. A servo motor 7 is arranged at the top of the vertical pipe 63. An auger shaft 8 is arranged inside the vertical pipe 63, and the auger shaft 8 is connected to the output shaft of the servo motor 7.

[0038] Based on the above, the material return mechanism plays the role of transporting the tea leaves back to the surface of the kneading plate 5. When the tea leaves fall from the leakage hole 52 into the feed funnel 61, the tea leaves slide along the inclined conveying pipe 62 to the inside of the vertical pipe 63 under the action of gravity, and move upward under the drive of the auger shaft 8. The tea leaves are discharged when they move to the inclined discharge pipe 64. The discharged tea leaves fall back to the surface of the kneading plate 5 and are kneaded again under the action of the kneading machine.

[0039] In actual use, the embodiment comprises a complete kneading machine composed of a kneading machine body 1, a crank mechanism 2, a kneading barrel 3, a pressure mechanism 4 and a kneading plate 5. The kneading machine is a traditional kneading machine. After pouring tea leaves into the kneading barrel 3, the pressure mechanism 4 is used to apply pressure to the tea leaves. When the kneading machine is powered on, the tea leaves are kneaded.

[0040] During the kneading operation, the guide strips 53 gather the tea leaves, so that the tea leaves always remain gathered. When the tea leaves follow the kneading barrel 3 to the leakage hole 52, the tea leaves fall from the leakage hole 52 to the inside of the feeding funnel 61 under the action of gravity, and slide into the inside of the vertical tube 63 along the inclined conveying pipe 62. At this time, the servo motor 7 is powered on to drive the auger shaft 8 to rotate, and the tea leaves are transported upward under the drive of the auger shaft 8 and discharged from the inclined discharge pipe 64. After the discharged tea leaves return to the surface of the kneading plate 5, the kneading operation is performed again.

[0041] Compared with the traditional kneading machine, the device has a leakage hole 52 on the surface of the kneading plate 5 and a return mechanism. By utilizing the characteristic that the tea leaves follow the movement of the kneading barrel 3 during the kneading process, the tea leaves can fall into the inside of the return mechanism and return to the surface of the kneading plate 5 under the action of the return mechanism. Through this return method, the position of the tea leaves is constantly changed, and the tea leaves wrapped in the middle can also be moved to the periphery, thereby achieving the effect of uniform kneading of the tea leaves.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
