Description

Technical Field

[0001] This utility model relates to the technical field of kneading devices, specifically a kneading device for processing oolong tea. Background Technology

[0002] Oolong tea is one of the six traditional tea categories in China, renowned worldwide for its unique color, aroma, and flavor. The processing of oolong tea involves multiple steps, including withering, rolling, pan-frying, sun-drying, and baking. Among these, the rolling process is crucial for developing the unique aroma and taste of oolong tea.

[0003] Traditional oolong tea rolling process mainly relies on manual operation, which is labor-intensive, inefficient, and makes it difficult to ensure the uniformity and consistency of rolling. With the rapid development of the tea industry, the market has increasingly higher requirements for the quality and quantity of oolong tea. Manual rolling can no longer meet the needs of modern tea production. Therefore, it is necessary to design rolling equipment to replace manual rolling.

[0004] According to CN218999445U, a multi-hole double-cylinder tea kneading machine with controllable kneading pressure is disclosed. This technology discloses a technical solution that includes "a table body and a support frame fixedly connected to the top of the table body. The top of the support frame is provided with a drive mechanism, the top of the table body is provided with two kneading mechanisms, and the bottom of the table body is provided with a control mechanism. The kneading mechanism includes two kneading discs fixedly connected to the top of the table body. It has the technical effect of driving the crankshaft to rotate through the motor, which in turn drives the connecting plate to swing and simultaneously drives the threaded rod to rotate. The rotation of the threaded rod drives the moving plate to move up and down. This allows the equipment to not only quickly knead the tea leaves, but also to control the rapid discharge through the rotation of the threaded rod, effectively improving the effect and efficiency of tea kneading."

[0005] The above design, while using a threaded rod to drive the discharge baffle vertically downward for rapid discharge control, causes tea leaves to accumulate on the baffle and scatter in all directions, making it difficult for the tea leaves to fall completely into the guide trough. Furthermore, the discharge baffle is typically located in the center of the kneading disc, and to ensure kneading efficiency, its top is usually positioned with a raised edge. When tea leaves fall onto the baffle, the horizontal descent and the obstruction of the raised edge hinder the discharge, requiring manual intervention and reducing the effectiveness of this structure. Therefore, we propose a kneading device for oolong tea processing to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-3 As shown:

[0031] A kneading device for processing oolong tea includes three sets of support legs 101 and a kneading disc 102 fixed between the three sets of support legs 101. A kneading mechanism 103 is arranged above the kneading disc 102 and is connected to the three sets of support legs 101. A baffle plate 104 is provided at the discharge port opened in the center of the kneading disc 102; it also includes:

[0032] Triangular prism 117 is fixed to the lower surface of baffle plate 104;

[0033] The material guide housing 105 is located below the kneading disc 102, and the material guide housing 105 has a sliding hole that matches the triangular prism 117.

[0034] U-shaped plate 110 is fixedly installed on the lower surface of the guide housing 105;

[0035] The second electric push rod 116 is fixedly installed on the lower surface of the U-shaped plate 110. The lower surface of the U-shaped plate 110 is provided with a through hole that matches the output end of the second electric push rod 116. The output end of the second electric push rod 116 can slide in the through hole of the U-shaped plate 110.

[0036] The connecting plate 112 is fixed to the bottom of the triangular prism 117, and a micro vibrator 115 is fixedly installed on the lower surface of the connecting plate 112. Abutment rods 113 arranged symmetrically are fixed on the upper surface of the connecting plate 112.

[0037] Spring 114 is sleeved on the surface of triangular prism 117, and the two ends of spring 114 are fixedly connected to guide housing 105 and connecting plate 112 respectively.

[0038] The connecting shaft 111 is provided in two sets and is rotatably mounted on both sides of the U-shaped plate 110 via bearings;

[0039] Two sets of first electric push rods 109 are provided and fixedly installed on the lower surface of the kneading disc 102. The output ends of the two sets of first electric push rods 109 are respectively corresponding to the connecting shaft 111. A connecting plate 107 is fixedly installed on the output end of the first electric push rod 109. One end of the connecting shaft 111 is fixed on one side of the corresponding connecting plate 107. A telescopic rod 108 arranged symmetrically is fixed between the connecting plate 107 and the kneading disc 102.

[0040] The elastic rope 106 is fixedly installed on the upper surface of the guide housing 105 away from the opening, and the other end of the elastic rope 106 is fixed to the lower surface of the kneading disc 102. The end of the guide housing 105 away from the elastic rope 106 is heavier.

[0041] In this implementation plan: When the oolong tea processing kneading device is in use, the oolong tea leaves are put into the placement bucket of the kneading mechanism 103. Under the rotation of the kneading mechanism 103, in conjunction with the kneading disc 102, the oolong tea leaves are kneaded.

[0042] After kneading, the material needs to be unloaded. At this time, the placement bucket on the kneading mechanism 103 corresponds to the baffle plate 104, and the diameter of the baffle plate 104 is larger than the diameter of the placement bucket of the kneading mechanism 103. By activating the first electric push rod 109, the connecting plate 107 is driven to move downward. The connecting plate 107 is connected to the connecting shaft 111, the U-shaped plate 110 and the guide housing 105, etc., so that these components move downward synchronously. The guide housing 105 separates from the bottom of the kneading disc 102, and at the same time, the baffle plate 104 detaches from the discharge port of the kneading disc 102. At this time, the oolong tea leaves fall through the discharge port and can land on the upper surface of the baffle plate 104.

[0043] During this process, when the guide housing 105 moves down, it is heavier because it is farther away from the elastic rope 106. The elastic rope 106 applies a pulling force to one end of the guide housing 105. At the same time, the center of gravity is unbalanced, causing the guide housing 105 to gradually tilt during the fall. The guide housing 105 rotates around the connecting shaft 111. As it tilts, the triangular prism 117 drives the baffle plate 104 to also tilt. This design allows the oolong tea leaves falling on the baffle plate 104 to be discharged more smoothly.

[0044] As the connecting plate 107 moves downward, it can also drive the telescopic rod 108 to stretch; the setting of the telescopic rod 108 ensures the stability of the connecting plate 107 when it drives the guide housing 105 and other components to move downward.

[0045] At the same time, the second electric push rod 116 is activated to release the pressure on the connecting plate 112. At this time, the spring 114, which is in a compressed state, returns to its initial state, causing the abutment rod 113 on the connecting plate 112 to separate from the guide housing 105. This will not affect the limiting sliding of the triangular prism 117 on the guide housing 105. At the same time, the micro vibrator 115 is activated. With the cooperation of the spring 114, the baffle plate 104 and the triangular prism 117 vibrate at a high frequency. The tea leaves on the baffle plate 104 will also move with the vibration. Even if the protruding edge on the baffle plate 104 blocks the tea leaves, the tea leaves on the tilted baffle plate 104 can fall off better.

[0046] In this design, by keeping the baffle plate 104 tilted and generating high-frequency vibrations during the feeding process, the oolong tea leaves can be discharged more effectively. This allows the tea leaves to be discharged more smoothly, reducing accumulation on the baffle plate 104, thereby reducing the need for manual intervention and alleviating labor intensity. Tea leaves falling from around the baffle plate 104 can land on the guide housing 105, ensuring that the tea leaves completely fall into the guide housing 105.

[0047] The triangular prism 117 adopts a triangular structure design. When tea leaves fall onto the guide housing 105, one side of the triangular prism 117 is pointed, which can reduce the obstruction to the tea leaves and allow the tea leaves to be discharged more smoothly on the guide housing 105.

[0048] Additionally, when the second electric push rod 116 is activated in reverse, the connecting plate 112 is squeezed, causing the abutment rod 113 on the connecting plate 112 to abut against the bottom surface of the guide housing 105. This design can limit the triangular prism 117 and ensure the stability of the baffle plate 104. When the first electric push rod 109 retracts, it drives the guide housing 105 to move upward, so that the upper surface of the guide housing 105 fits against the bottom of the kneading disc 102. This can limit the guide housing 105. This process further ensures the stability of the baffle plate 104 at the discharge port of the kneading disc 102.

[0049] It should be noted that all electrical equipment involved in this product is powered by an external power source. The solution also includes an electrical control cabinet, which is installed on the support leg 101. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those skilled in the art, so it will not be described in detail here.

[0050] It should be noted that the accessories used in the kneading disc 102 have been disclosed in publication number CN217791334U, and their performance can be referred to publication number CN217791334U (i.e., the "kneading drum assembly" disclosed in this prior art). All contents not described in detail in this specification are prior art known to those skilled in the art.

[0051] The working principle and usage process of this utility model are as follows: When using this oolong tea processing kneading device, oolong tea leaves are placed in the placement bin of the kneading mechanism 103. Under the rotation of the kneading mechanism 103, in conjunction with the kneading disc 102, the oolong tea leaves are kneaded. After kneading, a feeding operation is required. At this time, the placement bin on the kneading mechanism 103 corresponds to the baffle plate 104, and the diameter of the baffle plate 104 is larger than the diameter of the placement bin of the kneading mechanism 103. By activating the first electric push rod 109, the connecting rod is driven... The connecting plate 107 moves downward; the connecting plate 107 is connected to the connecting shaft 111, U-shaped plate 110, and guide housing 105, causing these components to move downward synchronously; the guide housing 105 separates from the bottom of the kneading disc 102, and at the same time, the baffle plate 104 detaches from the discharge port of the kneading disc 102. At this time, the oolong tea leaves fall through the discharge port and can land on the upper surface of the baffle plate 104; during this process, when the guide housing 105 moves downward, it is heavier due to its position away from the elastic rope 106, and the elastic rope 106 supports the guide housing. A pulling force is applied to one end of the guide housing 105, and the center of gravity is unbalanced, causing the guide housing 105 to gradually tilt during its descent. The guide housing 105 rotates around the connecting shaft 111. As it tilts, the triangular prism 117 causes the baffle plate 104 to also tilt. This design allows the oolong tea leaves falling on the baffle plate 104 to be discharged more smoothly. At the same time, the second electric push rod 116 is activated to release the pressure on the connecting plate 112. At this time, the spring 114, which was in a compressed state, returns to its initial state. This causes the abutment rod 113 on the connecting plate 112 to separate from the guide housing 105, so as not to affect the limiting sliding of the triangular prism 117 on the guide housing 105. At the same time, the micro vibrator 115 is activated, and with the cooperation of the spring 114, the baffle plate 104 and the triangular prism 117 vibrate at a high frequency. The tea leaves on the baffle plate 104 will also move with the vibration. Even if the protruding edge on the baffle plate 104 obstructs the tea leaves, the tea leaves on the tilted baffle plate 104 can fall off better.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
