Description

Technical Field

[0001] This utility model belongs to the field of tea processing technology, specifically, it relates to a multi-barrel tea kneading machine. Background Technology

[0002] Rolling is a crucial processing step in tea making. The purpose of rolling is to curl the tea leaves into strips, facilitating drying and shaping; simultaneously, it breaks down the tea cells, extracting tea juice, which is absorbed by the surface of the leaves, resulting in a rich and flavorful brew. Therefore, rolling is a primary process in shaping the appearance and quality of tea leaves and a key factor in determining their brewing endurance. Traditionally, tea rolling was done manually. However, with my country's economic development, to improve tea-making efficiency and reduce labor costs, the rolling process has gradually become mechanized and automated, leading to the development of tea rolling machines.

[0003] The working principle of existing tea rolling machines is basically the same. Their mechanical structure consists of a rolling disc, a rolling barrel, a triangular crank rotating mechanism, a pressure cap, and a pressure mechanism. The rolling disc is a concave disc with ribs on its upper surface; the rolling barrel is a bottomless and lidless metal cylinder that rotates in a circular motion on a horizontal plane above the rolling disc via the triangular crank rotating mechanism; the pressure cap is a disc of similar size to the diameter of the rolling barrel, which applies downward pressure to the tea leaves inside the rolling barrel via the pressure mechanism. Inside the rolling barrel, the tea leaves are repeatedly turned, kneaded, and rolled through the combined action of the rolling barrel's movement and the ribs' turning action, thus tightening the tea leaves, breaking down the cells, and squeezing out some tea juice, achieving the purpose of rolling.

[0004] However, current tea rolling machines typically only operate with a single rolling drum, resulting in low efficiency. To meet larger production demands, additional equipment must be added, which undoubtedly increases production and maintenance costs. Therefore, there is a strong need for a tea rolling machine that is more efficient and better suited for cost control. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-barrel tea kneading machine, which aims to solve the problem that existing tea kneading machines can only perform kneading through a single barrel.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-kneading tea rolling machine includes a support frame, a rolling disc, rolling drums, a pressure cap, and a pressure mechanism. The rolling disc is horizontally fixed on the support frame, and the rolling drums are positioned above the rolling disc. Ribs are provided on the upper surface of the rolling disc. The pressure cap is installed inside the rolling drums and applies downward pressure through the pressure mechanism. Multiple rolling drums are provided and are evenly spaced around the axis of the rolling disc. The machine also includes a rotating shaft that passes through the rolling disc and coincides with the axis of the rolling disc. A drive motor is connected to the lower end of the rotating shaft. The multiple rolling drums are all connected to the rotating shaft through horizontal connecting rods.

[0008] As a further preferred embodiment of this technical solution, the ribs are evenly distributed radially around the axis of the kneading disc, and the radial span of the ribs on the kneading disc is adapted to the outer diameter of the kneading drum.

[0009] As a further preferred embodiment of this technical solution, the prism is arc-shaped, and the concave direction of the arc of the prism is opposite to the rotation direction of the rotating axis.

[0010] As a further preferred embodiment of this technical solution, an internal gear ring is provided on the inner side of the flange of the kneading disc, and a matching external gear is provided on the outer wall of the kneading drum. The kneading disc and the kneading drum are installed by meshing with each other through the internal gear ring and the external gear.

[0011] As a further preferred embodiment of this technical solution, ribs are also provided on the inner wall of the kneading drum, and the ribs on the inner wall of the kneading drum are spiral-shaped, with the spiral direction of the ribs being the same as the rotation direction of the kneading drum.

[0012] As a further preferred embodiment of this technical solution, the diameter of the pressure cap is adapted to the inner diameter of the kneading drum, and ball bearings are arranged circumferentially on the edge of the pressure cap.

[0013] As a further preferred embodiment of this technical solution, the pressurizing mechanism includes a vertically arranged telescopic cylinder and an "L"-shaped connecting rod. The cylinder body of the telescopic cylinder is fixedly mounted on the rotating shaft, and the output shaft of the telescopic cylinder is connected to the pressure cap through the "L"-shaped connecting rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention changes the traditional crank-driven rotation method of tea rolling machines, employing a central rotary drive to simultaneously rotate multiple rolling drums above the rolling disc. This allows the tea leaves in multiple drums to rub against the ribs on the rolling disc simultaneously, achieving highly efficient rolling. Compared to traditional tea rolling machines, although the size of a single machine is larger, the drive rotation structure of this invention is simpler, has a lower failure rate, and facilitates later maintenance. The tea rolling efficiency of this invention can be increased exponentially with the number of rolling drums installed, and multiple rolling drums working simultaneously only require one drive unit, resulting in lower production costs and higher cost-effectiveness.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1 The multi-knead tea rolling machine shown includes a support frame 1, a kneading disc 2, a kneading drum 3, a pressure cap 4, and a pressure mechanism. The kneading disc 2 is horizontally fixed on the support frame 1. The kneading drum 3 is positioned above the kneading disc 2. Ribs 5 are provided on the upper surface of the kneading disc 2. The pressure cap 4 is installed inside the kneading drum 3 and applies downward pressure through the pressure mechanism. Multiple kneading drums 3 are provided, and the multiple kneading drums 3 are evenly spaced around the axis of the kneading disc 2. In this embodiment, two kneading drums 3 are provided, such as... Figure 1As shown, two kneading drums 3 are symmetrically arranged above the kneading disc 2; a rotating shaft 6 is also included, which passes through the kneading disc 2 and coincides with the axis of the kneading disc 2. The rotating shaft 6 is connected to the kneading disc 2 by a bearing, and a drive motor 7 is connected to the lower end of the rotating shaft 6; multiple kneading drums 3 are connected to the rotating shaft 6 by horizontal connecting rods 8. In this embodiment, the connection structure between the kneading drum 3 and the horizontal connecting rod 8 is as follows: a ring adapted to the outer diameter of the kneading drum 3 is fixedly connected to the end of the horizontal connecting rod 8. The ring is sleeved on the outer wall of the kneading drum 3. It should also be noted that the connection point of each horizontal connecting rod 8 on the rotating shaft 6 is consistent, and the connection is made by a universal joint.

[0023] Specifically, in this embodiment, the support frame 1 consists of three columns arranged in an equilateral triangle shape; the kneading disc 2 is a concave disc, horizontally fixed to the upper end of the three columns; the kneading barrel 3 is a metal cylinder without a bottom or cover, installed above the kneading disc 2, specifically with the bottom plane of the kneading barrel 3 roughly level with the height of the ribs 5 on the kneading disc 2; the pressure cap 4 is a disc of similar size to the diameter of the kneading barrel 3, used to seal the kneading barrel 3 and to pressurize and loosen the tea leaves inside the kneading barrel 3 through the pressurizing mechanism during feeding and discharging. The pressure cap 4 can be completely detached from the kneading drum 3; the pressurizing mechanism includes a vertically arranged telescopic cylinder 11 and an "L"-shaped connecting rod 12. The cylinder body of the telescopic cylinder 11 is fixedly installed on the rotating shaft 6. The output shaft of the telescopic cylinder 11 is connected to the pressure cap 4 through the "L"-shaped connecting rod 12. When the output shaft of the telescopic cylinder 11 extends upward, it can drive the "L"-shaped connecting rod 12 and the pressure cap 4 to move upward, thereby releasing the pressure of the tea or pushing out the pressure cap 4. When the output shaft of the telescopic cylinder 11 retracts downward, it can drive the "L"-shaped connecting rod 12 and the pressure cap 4 to move downward, thereby pressurizing the tea.

[0024] The workflow of this embodiment is as follows: First, the output axis of the telescopic cylinder 11 is controlled to extend upward, lifting the pressure cap 4 and separating it from the kneading drum 3. Then, an appropriate amount of tea leaves are loaded into the kneading drum 3. Next, the output axis of the telescopic cylinder 11 is controlled to retract downward, allowing the pressure cap 4 to enter the kneading drum 3 and continuously press downward until it reaches the pressing line of the tea leaves. Then, the drive motor 7 is started, driving the rotating shaft 6 to rotate, which in turn drives the horizontal connecting rod 8 connected to the rotating shaft 6 and the kneading drum 3 to rotate around the axis of the kneading disc 2. During the rotation, the tea leaves in the kneading drum 3 rub and squeeze against the ribs 5 on the kneading disc 2, realizing the kneading of the tea leaves. Finally, after the tea leaves are kneaded, the drive motor 7 is turned off, and the output axis of the telescopic cylinder 11 is controlled to extend upward, lifting the pressure cap 4 and separating it from the kneading drum 3 for discharging.

[0025] Example 2

[0026] This embodiment is a further supplement to embodiment 1. In this embodiment, the ribs 5 on the kneading plate 2 are evenly distributed radially around the axis of the kneading plate 2, and the radial span of the ribs 5 on the kneading plate 2 is adapted to the outer diameter of the kneading barrel 3; the ribs 5 are arc-shaped, and the concave direction of the arc of the ribs 5 is opposite to the rotation direction of the rotating shaft 6.

[0027] like Figure 2 As shown, in this embodiment, in order to ensure that the ribs 5 can be evenly distributed on the kneading pan 2 and to ensure the uniformity of tea kneading, the ribs 5 are provided with two layers, an outer layer of ribs 5 that are sparser and an inner layer of ribs 5 that are denser. The two layers intersect and combine to form the rib system on the kneading pan 2.

[0028] Example 3

[0029] This embodiment is a further supplement to embodiment 1. In this embodiment, an internal gear ring 9 is provided on the inner side of the flange of the kneading disc 2, and a matching external gear 10 is provided on the outer wall of the kneading drum 3. The kneading disc 2 and the kneading drum 3 are installed by meshing with each other through the internal gear ring 6 and the external gear 10.

[0030] When the rotating shaft 6 drives all the kneading drums 3 to rotate above the kneading disc 2, the outer wall of the kneading drum 3 and the inner side of the flange of the kneading disc 2 are meshed by gears. On this basis, the kneading drum 3 will also be driven to rotate, thereby improving the friction and compression effect of the tea leaves in the kneading drum 3 and improving the kneading quality.

[0031] Example 4

[0032] This embodiment is a further supplement to embodiment 3. In this embodiment, a rib 5 is also provided on the inner wall of the kneading drum 3, and the rib 5 on the inner wall of the kneading drum 3 is spiral in shape. The spiral direction of the rib 5 is the same as the rotation direction of the kneading drum 3.

[0033] Traditional tea rolling machines only have ribs 5 on the rolling disc 2, while the inner wall of the rolling drum 3 is smooth. The drawback of this design is that when the rolling drum 3 rotates, the tea leaves are only rubbed and squeezed by the ribs 5 on the rolling disc 2, which is insufficient to roll all the tea leaves in the rolling drum 3 properly. Therefore, in this embodiment, ribs 5 are provided on the inner wall of the rolling drum 3. When the rolling drum 3 rotates, friction and squeezing also occur between the tea leaves and the ribs 5 on the inner wall of the rolling drum 3, achieving rolling. This further improves the rolling efficiency and quality of the tea leaves. Furthermore, the spiral-shaped ribs 5 provide an upward lifting force for the tea leaves during the rotation of the rolling drum 3, facilitating the axial movement of the tea leaves within the drum and ensuring that all the tea leaves in the rolling drum 3 are rolled properly.

[0034] On the other hand, in order to ensure that the pressure cap 4 can completely cover the internal cross-sectional area of ​​the kneading drum 3, the diameter of the pressure cap 4 is adapted to the inner diameter of the kneading drum 3; and based on the above-mentioned working mode of the kneading drum 3 rotating, the kneading drum 3 and the pressure cap 4 need to overcome rotational friction. At the same time, since the pressure cap 4 needs to move up and down inside the kneading drum 3, it also needs to overcome sliding friction. Therefore, in this embodiment, ball bearings are arranged circumferentially on the edge of the pressure cap 4, and the ball bearings can simultaneously meet the needs of sliding and rotation.

[0035] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 the present invention should be included within the protection scope of the present invention.
