Description

Technical Field

[0001] This utility model relates to the technical field of tea rolling machines, and in particular to a fully automatic tea rolling machine that automatically turns and evenly distributes tea leaves. Background Technology

[0002] Several tea processing plants have reported that during the traditional tea rolling process, tea leaves tend to accumulate on the edge of the stainless steel rolling pan, resulting in uneven rolling force between the edge and center tea leaves, which affects the overall quality of the tea rolling.

[0003] In particular, when processing multiple batches of different types of tea, tea scraps left on the edge of the kneading pan can mix into the next batch of tea, causing cross-contamination. This results in approximately 2% to 4% of the finished tea in each batch failing to meet purity standards, leading to an increase in customer complaints.

[0004] The cleaning and maintenance process is even more troublesome. It requires manual cleaning of residual tea leaves from the edges of the kneading pans after the machine is stopped. Each production line is interrupted at least three times per shift, with each cleaning session taking 20-25 minutes, directly impacting daily processing volume. Some manufacturers reduce the number of cleaning sessions to increase output, which actually exacerbates the problems of uneven tea kneading and cross-contamination. 25% of the after-sales feedback received is related to tea leaf accumulation on the edges of the kneading pans. Utility Model Content

[0005] Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a fully automatic tea rolling machine that automatically turns and evens out tea leaves. This solves the technical problem reported by many tea processing plants: during the rolling process of traditional tea rolling machines, tea leaves tend to accumulate on the edge of the stainless steel rolling pan, resulting in uneven rolling force between the edge tea leaves and the center tea leaves, which affects the overall quality of the tea rolling.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A fully automatic tea leaf rolling machine for automatic leaf turning and even distribution includes a support platform with three rotating cranks, a stainless steel rolling drum connected to the three rotating cranks, a rolling lid lifting assembly on the stainless steel rolling drum, and a stainless steel rolling disc on the support platform. Friction rings are installed through each of the three rotating cranks, and a raising ring is provided on the stainless steel rolling disc. A cleaning mechanism is located within the raising ring, and the cleaning mechanism is used to sweep tea leaves from the edge of the stainless steel rolling disc towards the center. The friction rings drive the rotation of the cleaning mechanism.

[0010] Preferably, three limiting rollers are equidistantly arranged on the circumference of the support platform, a limiting groove is formed on the circumferential surface of the heightening ring, the circumferential surfaces of the three limiting rollers are all in contact with the limiting groove formed on the heightening ring, and the three friction rings are all in contact with the circumferential surface of the heightening ring.

[0011] Preferably, the cleaning mechanism includes a connecting plate, which is fixedly mounted on a heightening ring. A shovel plate is fixedly mounted on the connecting plate, with its bottom edge fitting against the bottom of the inner wall of the stainless steel kneading disc. A support rod is fixedly mounted on the connecting plate, and a cleaning brush is mounted on the support rod via a bearing.

[0023] This application provides a fully automatic tea rolling machine that automatically turns and evens out the leaves, effectively solving the technical problem reported by many tea processing plants: during the rolling process of traditional tea rolling machines, tea leaves tend to accumulate on the edge of the stainless steel rolling pan, resulting in uneven rolling force between the edge tea leaves and the center tea leaves, which affects the overall quality of the tea rolling.

[0024] Example

[0025] like Figure 1 - Figure 7 As shown, the technical solution in this application aims to effectively address the technical problem reported by multiple tea processing plants: during the kneading process of traditional tea kneading machines, tea leaves tend to accumulate on the edge of the stainless steel kneading disc, resulting in uneven kneading force between the edge and center tea leaves, thus affecting the overall quality of the tea kneading. The general approach is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a fully automatic tea kneading machine for automatically turning and evenly distributing tea leaves. It includes a support platform 8, on which three rotating cranks 6 are provided. One of the rotating cranks 6 has a drive motor at its lower end. A stainless steel kneading drum 9 is provided on the support platform 8 and is connected to the three rotating cranks 6. A kneading cover lifting assembly 4 is provided on the stainless steel kneading drum 9. A stainless steel kneading disc 7 is provided on the support platform 8.

[0027] Friction rings 5 ​​are installed through each of the three rotating cranks 6. A heightening ring 1 is provided on the stainless steel kneading disc 7. A cleaning mechanism is provided inside the heightening ring 1. The cleaning mechanism is used to sweep the tea leaves on the edge of the stainless steel kneading disc 7 toward the center. The friction rings 5 ​​are used to drive the rotation of the cleaning mechanism.

[0028] like Figure 2 and Figure 6As shown, three limiting rollers 3 are equidistantly arranged on the circumference of the support platform 8. A limiting groove 2 is opened on the circumferential surface of the heightening ring 1. The circumferential surfaces of the three limiting rollers 3 are all in contact with the limiting groove 2 opened on the heightening ring 1. The three friction rings 5 ​​are all in contact with the circumferential surface of the heightening ring 1. When the crank 6 is rotated by the drive motor, it can drive the friction rings 5 ​​to rotate. Since the friction rings 5 ​​and the surface of the heightening ring 1 have high friction, the heightening ring 1 can rotate with it. Under the limitation of the three limiting rollers 3, it can be ensured that the center of rotation of the heightening ring 1 is the same as the center of the stainless steel kneading disc 7.

[0029] like Figure 3 and Figure 4 As shown, the cleaning mechanism includes a connecting plate 12, which is fixedly mounted on the raising ring 1. A scraper plate 16 is fixedly mounted on the connecting plate 12, with its bottom edge fitting against the bottom of the inner wall of the stainless steel kneading disc 7. A support rod 11 is fixedly mounted on the connecting plate 12, and a cleaning brush 15 is mounted on the support rod 11 via a bearing. The lower end of the cleaning brush 15 fits against the scraper plate 16, and a friction block 14 is installed through the cleaning brush 15. The circumferential surface of the friction block 14 fits against the inner wall of the stainless steel kneading disc 7. An electronic fan is provided on the connecting plate 12. When the cleaning mechanism cleans the tea leaves on the edge of the stainless steel kneading disc 7, the shovel plate 16 can scoop up the tea leaves. Then, because the friction block 14 is attached to the stainless steel kneading disc 7, when the raising ring 1 rotates, the friction block 14 rubs against the stainless steel kneading disc 7. The friction block 14 can also rotate, so that the cleaning brush 15 can clean the tea leaves on the edge of the stainless steel kneading disc 7. Then, the electronic fan 13 set in the connecting plate 12 can blow air, thereby cleaning the tea leaves to the middle of the stainless steel kneading drum 9 and the stainless steel kneading disc 7.

[0030] Working principle:

[0031] The first step is to start the equipment. The drive motor drives the three rotating cranks 6 to rotate. Since the stainless steel kneading barrel 9 is connected to the rotating cranks 6, the stainless steel kneading barrel 9 moves eccentrically with the rotating cranks 6. It cooperates with the stainless steel kneading disc 7 fixed on the support platform 8 to knead the tea leaves. The lifting component 4 of the kneading barrel can adjust the height according to the amount of tea leaves to ensure that the kneading pressure is appropriate and improve the kneading effect.

[0032] In the second step, when the crank 6 is rotated, the friction ring 5 installed through it rotates synchronously. Because the friction ring 5 is attached to the circumferential surface of the raising ring 1 and the two have high friction, the rotation of the friction ring 5 drives the raising ring 1 to rotate accordingly. The three limiting rollers 3 on the support platform 8 are attached to the limiting grooves 2 of the raising ring 1, restricting the movement trajectory of the raising ring 1 and ensuring that it rotates stably around the center of the stainless steel rubbing disc 7, providing a stable foundation for subsequent cleaning operations.

[0033] In the third step, when the heightening ring 1 rotates, the connecting plate 12 fixed on it drives the entire cleaning mechanism to rotate synchronously. The shovel plate 16 below the connecting plate 12 is in contact with the bottom of the inner wall of the stainless steel kneading pan 7. As it rotates, it shovels up the tea leaves accumulated at the edge of the kneading pan, preventing the tea leaves from accumulating at the edge and causing uneven kneading. The lower end of the cleaning brush 15 on the support rod 11 is in contact with the shovel plate 16. At the same time, the friction block 14 on the cleaning brush 15 is in contact with the inner wall of the stainless steel kneading pan 7. As the cleaning mechanism rotates, the friction block 14 rubs against the inner wall of the kneading pan and generates its own rotation, which drives the cleaning brush 15 to rotate, further cleaning and breaking up the tea leaves on the shovel plate 16 to prevent the tea leaves from clumping.

[0034] In the fourth step, the electronic fan 13 on the connecting plate 12 is started during operation, blowing air towards the center of the shovel plate 16. The tea leaves that are scooped up by the shovel plate 16 and dispersed by the cleaning brush 15 are blown by the fan into the middle area between the stainless steel kneading drum 9 and the stainless steel kneading disc 7, and re-participate in the kneading operation.

[0035] Through the above cycle, the tea leaves are continuously gathered from the edges to the center during the rolling process, achieving automatic leaf turning and even distribution, ensuring that all tea leaves are subjected to uniform rolling pressure, and improving the rolling quality of the tea leaves.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
