Description

Technical Field

[0001] The utility model belongs to the technical field of spreading green tea devices, in particular to a spreading green tea device for dark tea production and processing. Background Art

[0002] Spreading the leaves is a crucial step in tea processing, particularly in the production of green and oolong teas. Spreading the leaves, also known as withering or airing, involves spreading the freshly picked leaves evenly in a well-ventilated, dark environment to allow them to naturally lose water. This process helps regulate the moisture content of the leaves, preparing them for subsequent processing steps, and also significantly impacts the tea's aroma and taste.

[0003] For example, a continuous tea spreading machine with publication number CN111903792B includes a tea spreading feeding device, a turning machine arranged at the discharge end of the tea spreading feeding device, a roller conveyor line located below the outlet of the turning machine, a screen frame arranged on the roller conveyor line, and a recovery device with a feed end located below the roller conveyor line, and the discharge end of the recovery device transports the tea leaves into the tea spreading feeding device. The continuous tea spreading machine of the present invention has a reasonable overall structure, occupies a small space, has a high degree of automation, can carry out uninterrupted tea spreading processing, improves the production efficiency of the tea spreading process, reduces the labor intensity of tea spreading, and saves a lot of manpower. It includes a tea spreading feeding device, a turning machine arranged at the discharge end of the tea spreading feeding device, a roller conveyor line located below the outlet of the turning machine, a screen frame arranged on the roller conveyor line, and a recovery device with a feed end located below the roller conveyor line, and the discharge end of the recovery device transports the tea leaves into the tea spreading feeding device. The continuous tea spreading machine of the present invention has a reasonable overall structure, occupies a small space, has a high degree of automation, can perform uninterrupted tea spreading processing, improves the production efficiency of the tea spreading process, reduces the labor intensity of spreading, and saves a lot of manpower;

[0004] During the use of this tea spreading equipment, since the discharge port is larger than the screen frame, some tea leaves will fall onto the material belt outside the screen frame during the discharge process. The tea leaves on the material belt need to be re-transported to the discharge mechanism for cyclic discharge. On the one hand, the contact time of tea leaves with dust will increase during multiple transportation processes. On the other hand, multiple transportations consume more time. In order to solve the above problems, a tea spreading device for black tea production and processing is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a device for spreading green tea for producing and processing dark tea in order to solve the above problems, comprising:

[0008] The block release mechanism is fixedly installed on one side of the upper end of the column;

[0012] Through the above technical solution, after the agglomerated tea leaves are placed in the deagglomeration box, the agglomerated tea leaves are decomposed into multiple small pieces of tea leaves through the high-speed rotation of the crushing roller. The small pieces of tea leaves enter the upper surface of the vibrating guide plate and are dispersed to prevent the tea leaves from agglomerating and being difficult to flatten.

[0013] In a preferred embodiment, a first motor is fixedly mounted on the other side of the upper surface of the fixing frame, and a transmission belt is provided between the output shaft of the first motor and the end of the crushing roller.

[0017] Through the above technical solution, when the tea leaves are flattened, the baffle is lifted by rotating the second motor, thereby moving the screen frame with the tea leaves flattened through the belt conveyor.

[0018] In a preferred embodiment, the guide plate is located directly above the flattening ring.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: the present invention proposes a green tea spreading device for the production and processing of dark tea.

[0020] The screen frame is placed on the upper surface of the belt conveyor, and the screen frame is transported by the belt conveyor. The screen frame transported to the bottom of the flattening ring is blocked by the blocking mechanism, and the black tea to be flattened is placed on the upper surface of the deblocking mechanism.

An electric telescopic rod 22 is fixedly mounted on one side of the electric slider 21. A flattening ring 23 is fixedly mounted on the output shaft end of the electric telescopic rod 22. The electric telescopic rod 22 reciprocates to flatten the tea leaves entering the sieve frame. At the same time, the flattening ring 23 limits the position of the tea leaves to prevent them from entering the belt conveyor 1. This optimizes the existing tea spreading machine and improves the tea spreading efficiency.

[0029] The deblocking mechanism 3 is fixedly installed on one side of the upper end of the column 2. The deblocking mechanism 3 also includes a fixed frame 31. A deblocking box 32 is fixedly installed on the upper surface of the fixed frame 31. A crushing roller 33 is rotatably connected inside the deblocking box 32. A first motor 34 is fixedly installed on the other side of the upper surface of the fixed frame 31. A transmission belt is provided between the output shaft of the first motor 34 and the end of the crushing roller 33. The crushing roller 33 is driven to rotate by the operation of the first motor 34. A plurality of connecting rods 35 are fixedly installed on the outer wall of the fixed frame 31 to connect A spring rod 36 is fixedly mounted at the bottom of the rod 35, and a guide plate 37 is fixedly mounted at the bottom of the spring rod 36. The guide plate 37 is located directly above the flattening ring 23 and is arranged in an inclined surface. A vibration motor 38 is fixedly mounted on the outer wall of the lower end of the guide plate 37. After the agglomerated tea leaves are placed in the deagglomeration box 32, the agglomerated tea leaves are decomposed into a plurality of small tea leaves by the high-speed rotation of the crushing roller 33. The small tea leaves enter the upper surface of the vibrating guide plate 37, which disperses the small tea leaves and prevents the tea leaves from agglomerating and being difficult to flatten.

[0030] The blocking mechanism 4 is fixedly mounted on the outer wall on the other side of the belt conveyor 1. A baffle 41 is rotatably connected to one side of the blocking mechanism 4. A second motor 42 is fixedly mounted on the other side of the blocking mechanism 4. The output shaft of the second motor 42 is fixedly connected to one side of the baffle 41. When the tea leaves are flattened, the baffle 41 is lifted by rotating the second motor 42, thereby moving the screen frame after the tea leaves are flattened through the belt conveyor 1.

[0031] Working principle:

[0032] The sieve frame is placed on the upper surface of the belt conveyor 1, and the sieve frame is transported by the belt conveyor 1. The sieve frame transported to the bottom of the flattening ring 23 is blocked by the blocking mechanism 4, and the black tea to be flattened is placed on the upper surface of the deblocking mechanism 3. The deblocked tea leaves are dispersed by the deblocking mechanism 3, and the dispersed tea leaves enter the sieve frame through the flattening ring 23. At this time, the electric telescopic rod 22 reciprocates to flatten the tea leaves entering the sieve frame, and the flattening ring 23 is used to limit the tea leaves to prevent them from entering the belt conveyor 1. The existing spreading machine is optimized to improve the spreading efficiency.
