Description

Technical Field

[0001] This utility model belongs to the field of tea processing technology, specifically relating to a kneading device for tea processing. Background Technology

[0002] Rolling is a crucial process in shaping the appearance and internal qualities of tea leaves. Its main functions are to break down tea cells, extract tea juice, and produce a richer, more flavorful brew, while also shaping the tea leaves initially. The main working structure of a tea rolling machine consists of a rolling disc, a rolling drum, a pressure plate, and ribs. The rolling drum moves the tea leaves in a circular motion at a certain speed, while the pressure plate applies pressure to the tea leaves on the rolling disc. During this process, the tea leaves interact with the ribs on the rolling disc, resulting in a series of forces that complete the rolling process.

[0003] In existing tea processing kneading devices, the kneading ribs are typically fixed to the kneading disc and difficult to disassemble. Different varieties and sizes of tea require different kneading forces. For some high-quality teas, the kneading ribs needed for processing different varieties and sizes may differ from those needed for ordinary teas. In such cases, workers can only change to different kneading machines, which is costly for small processing plants. Therefore, we provide a tea processing kneading device to solve these problems.

The output end of the servo motor is threadedly connected to a convex slider, which is slidably connected inside the kneading disc. The outer surface of the convex slider has eight grooves, and each groove has a rotatable guide rod rotatably connected inside it. Each guide rod has a fixed rib block on its outer surface, and each rib block has a fixed rubber sleeve on its outer surface. The bottom surface of the kneading disc has eight through holes.

This design allows the kneading device to flexibly adjust the height and angle of the rib block according to different tea types and processing requirements, so as to achieve the best kneading effect. It plays a role in giving the tea kneading device a multi-dimensional adjustable function, improving the quality and applicability of tea processing.

[0016] (2) This utility model, by setting a linkage mechanism driven by a synchronous motor, can realize the stable movement and precise positioning of the kneading drum. The synchronous motor drives the linkage block to move through the rotating shaft. The linkage block is connected to the fixed frame through the second transmission shaft, thereby realizing the movement control of the kneading drum. At the same time, through the cooperation of the threaded rod and the pressure cover, the pressure inside the kneading drum can be adjusted as needed to further optimize the kneading effect. This design enables the kneading device to realize the stable movement of the kneading drum and the precise control of the pressure, ensuring the uniformity and stability of the tea kneading process and improving the processing quality of the tea. In addition, the setting of the support seat and support legs ensures the stability and reliability of the entire device, and plays a role in enabling the tea kneading device to have stable and reliable operating performance, improving the processing efficiency and quality of tea.

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] Reference Figures 1 to 6As shown, this utility model embodiment provides a kneading device for tea processing, specifically including a kneading disc 1 and a kneading cylinder 2. An adjustment mechanism 3 is provided inside the kneading disc 1. The adjustment mechanism 3 includes a servo motor 301, which is located below the kneading disc 1. The output end of the servo motor 301 is threadedly connected to a convex slider 302, which is slidably connected inside the kneading disc 1.

The outer surface of each rubber sleeve 306 is fixedly connected to the inner wall of the through hole 307. One end of each steering rod 304 is fixedly connected to a gear 308.

The top end of the worm wheel 313 is fixedly connected to the bottom surface of the external gear ring 309. The servo motor 301 drives the convex slider 302 to move along the axial direction. When the convex slider 302... When moving along the axial direction, it can drive the rib block 305 to adjust its height; at the same time, the limit frame 318 can effectively limit the stroke of the convex slider 302. By utilizing the eight grooves 303 opened on the outer surface of the convex slider 302 and their cooperation with the steering rod 304, and then through the stepper motor 311 driving the worm gear 313 and worm 312 to drive the meshing transmission of the external gear ring 309 and the gear 308, the angle adjustment of the rib block 305 can be realized synchronously, ensuring the consistency and stability of the angle adjustment of the rib block 305.

[0021] Reference Figures 1 to 6As shown, three support frames 314 are fixedly connected to the outer surface of the kneading disc 1. A support base 315 is fixedly connected to the bottom surface of the three support frames 314. Several support legs 316 are fixedly connected to the bottom surface of the support base 315. Through the cooperation of the support base 315 and the support legs 316, stable support can be provided for the entire device, ensuring stability and reliability during the kneading process. Several electric telescopic rods 317 are fixedly connected to the upper surface of the support base 315. The telescopic ends of the electric telescopic rods 317 are fixedly connected to the bottom surface of the bearing sleeve 310. The height of the bearing sleeve 310 can be adjusted through the electric telescopic rods 317, thereby better adapting to different tea processing needs in conjunction with the adjustment mechanism 3. A limiting frame 318 is fitted onto the outer surface of the convex slider 302. The bottom surface of the limiting frame 318 is fixedly connected to the inner bottom wall of the outer gear ring 309. The limiting frame 318 can limit and guide the movement of the convex slider 302, ensuring that the convex slider 302 can move stably along the axial direction and preventing it from deviating.

[0022] Reference Figures 1 to 6 As shown, a synchronous motor 319 is fixedly connected to the upper surface of the support base 315, and a rotating shaft 320 is fixedly connected to the output end of the synchronous motor 319. A first transmission shaft 321 is fixedly connected to the upper surface of each of the two support frames 314. A connecting rod block 322 is provided on the upper surface of each support frame 314. The outer surfaces of the two first transmission shafts 321 are rotatably connected to two of the connecting rod blocks 322 respectively. The top end of the rotating shaft 320 passes through another support frame 314 and is fixedly connected to the bottom surface of one of the connecting rod blocks 322. A second transmission shaft 323 is rotatably connected to the upper surface of each connecting rod block 322. The top ends of the three second transmission shafts 323 are fixedly connected to a fixed frame 324. The inner wall of the fixed frame 324 is fixedly connected to the outer surface of the kneading drum 2. The synchronous motor 319 drives the connecting rod block 322 to move through the rotating shaft 320. The connecting rod block 322 is connected to the fixed frame 324 through the second transmission shaft 323, thereby realizing the motion control of the kneading drum 2 and achieving stable movement and precise positioning of the kneading drum 2.

[0023] Reference Figures 1 to 6 As shown, a positioning frame 325 is fixedly connected to the upper surface of the fixed frame 324. A threaded rod 326 is threadedly connected inside the positioning frame 325. The positioning frame 325 provides good support and positioning for the threaded rod 326, ensuring that the threaded rod 326 can drive the pressure cover 328 to move with the fixed frame 324. A handle 327 is fixedly connected to the top of the threaded rod 326, and a pressure cover 328 is fixedly connected to the bottom of the threaded rod 326. By rotating the threaded rod 326 through the handle 327, the pressure cover 328 can be moved up and down inside the kneading drum 2, thereby adjusting the pressure inside the kneading drum 2 as needed and further optimizing the kneading effect.

[0024] In use, the tea leaves to be processed are placed inside the kneading drum 2. Then, the threaded rod 326 is rotated via the handle 327 to adjust the position of the pressure cover 328 inside the kneading drum 2 to set a suitable initial pressure. The servo motor 301 in the adjustment mechanism 3 is activated. The output of the servo motor 301 drives the convex slider 302 to move along the axial direction. Utilizing the eight grooves 303 on the outer surface of the convex slider 302 in cooperation with the steering rod 304, the eight rib blocks 305 are synchronously driven to adjust their height until a suitable height for the current tea type is reached. At this point, the stepper motor 311 is activated. The output of the stepper motor 311 drives the worm gear 312 to rotate. The worm gear 312, through meshing with the worm wheel 313, drives the external gear ring 309 to rotate. The external gear ring 309, through meshing with the eight gears 308, synchronously drives the eight steering rods 304 to rotate, thereby realizing the rotation of the eight rib blocks 305. The synchronous angle adjustment of 05 ensures that the angles of all the rib blocks 305 are consistent. After the height and angle adjustment of the rib blocks 305 are completed, the synchronous motor 319 drives one of the connecting rod blocks 322 to rotate. The connecting rod block 322 drives the fixed frame 324 to move through the second transmission shaft 323. The other two connecting rod blocks 322 rotate through the two first transmission shafts 321 fixed on the fixed frame 324, thereby achieving stable movement and precise positioning of the kneading cylinder 2. This ensures that the tea leaves are in full contact with the rib blocks 305 on the kneading disc 1 inside the kneading cylinder 2, completing the kneading process. During the kneading process, the position of the pressure cover 328 can be adjusted again through the handle 327 as needed to optimize the kneading effect. Furthermore, when processing different types of tea, the height of several electric telescopic rods 317 can be adjusted in conjunction with the adjustment mechanism 3 to achieve precise adaptation to different types of tea. The rubber sleeve 306 fixedly connected to the outer surface of each rib block 305 can optimize the sealing effect of the through hole 307 opened on the kneading disc 1 when the angle of the rib block 305 is adjusted, preventing tea from leaking out of the through hole 307. This design allows the tea kneading device to flexibly adjust the height and angle parameter combination of the rib block 305 according to different types of tea and processing requirements, achieving precise kneading, effectively improving the forming rate and quality uniformity of tea, and greatly improving the applicability, efficiency and quality of tea processing.
