Tea beverages made from tea are one of the three major beverages in the world.
[0003] Rolling is a basic process in tea making, which forms its tight and curved appearance and also affects the improvement of internal quality. Rolling can tighten the tea leaves, reduce their volume, lay a good foundation for frying and drying, and appropriately destroy the leaf tissue and material transformation.
[0004] The pressure of rolling tea leaves should be controlled as "light, heavy, light", because at the beginning, the tea leaves are still relatively fragile, the tea juice has not yet broken, and has not been rolled out, so light pressure is used. When the tea juice comes out in the middle, the tea leaves are relatively moist, so heavy pressure can be used. Finally, the tea leaves are basically formed to prevent them from being broken into strips. Try to roll them as lightly as possible. It is difficult to control the pressure of existing rolling machines. The rolled tea leaves may break due to excessive rolling or become bitter due to insufficient rolling, which affects the product quality. In addition, during the rolling process of tea leaves on existing tea rolling machines, the tea leaves are easy to adhere to the rolling plate or the inner wall of the rolling barrel.

[0016] The utility model has the following advantages and beneficial effects:
[0017] 1. The utility model has several rotatable rollers in the rotating drum, and the rollers are set as a conical table with a small top and a large bottom. This design can better control the pressure of tea leaves. When the tea leaves are just put in, the kneading cavity space is larger, and the relative kneading pressure is smaller; the kneaded tea leaves further fall to the drum surface with a larger diameter, and are kneaded with a larger contact area and a greater contact pressure; finally, the kneaded tea leaves put into the piston cylinder are kneaded again by the piston. The more tea leaves in the piston cylinder, the greater the kneading pressure, and finally a certain pressure is released through the pressure control valve.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.
[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] Example
[0026] like Figure 1 As shown, a tea rolling machine comprises a frame 1, a piston cylinder 4, a piston 36, a crank rocker mechanism 3 and a rotating cylinder 5. The upper end of the piston cylinder 4 is fixed to the inner wall of the frame 1 through a locking block 14. The inner wall of the piston cylinder 4 is slidably provided with a piston 36. The piston 36 is rotatably connected to the crank rocker mechanism 3. The two ends of the rotating cylinder 5 are rotatably provided on the outer wall of the piston cylinder 4 through a first bearing 51 and a second bearing 54. The lower end of the rotating cylinder 5 is connected to a driving mechanism 6, so that the driving mechanism 6 can drive the rotating cylinder 5 to rotate. A rolling cavity 53 is formed between the rotating cylinder 5 and the piston cylinder 4. The upper section of the piston cylinder 4 is provided with a tea inlet cavity 41, which is connected to the rolling cavity 53. The lower side of the rotating cylinder 5 is provided with a first outlet 432, which is connected to the piston cavity 42 of the piston cylinder 4. The bottom end of the piston cylinder 4 is provided with a pressure control valve 46.
[0027] The tea rolling machine designed by the utility model is designed to rotate the drum 5 around the piston cylinder 4, so that the tea leaves are not easy to stick when rolling. The rotating drum 5 can ensure the cleanliness of the rolling cavity 53, and ensure that the rolled tea leaves can be discharged through the first outlet 432 at the first time, so as not to destroy the composition of the tea leaves by excessive rolling. Secondly, the tea leaves entering the piston cavity 42 from the first outlet 432 can be rolled twice by the piston 36, so as to achieve the requirements of multiple rolling processes and ensure the effect of tea rolling. In addition, when the amount of tea leaves in the piston cavity 42 is small, the rolling pressure of the tea leaves in the piston cavity 42 is small. As more and more tea leaves enter the piston cavity 42, the pressure of the piston 36 rolling the tea leaves increases, so as to achieve the requirements of the rolling process of gradually increasing pressure from small to large. After reaching a certain pressure, the pressure control valve 46 automatically opens, and the rolled tea leaves are discharged. Such a design can not only achieve the process requirements of multiple rolling, but also control the rolling pressure of the tea leaves, so as to ensure the quality requirements of tea rolling.
[0028] A tea rolling machine includes a conical discharge funnel 2, a stable channel 11 is arranged on the inner wall of a frame 1, the conical discharge funnel 2 is arranged on the inner wall of the stable channel 11, and the bottom of the conical discharge funnel 2 is tightly connected to the upper side of a piston cylinder 4. A first channel 21 is arranged inside the conical discharge funnel 2, the first channel 21 is connected to a tea inlet cavity 41, and a flow control valve 22 is arranged on the first channel 21.
[0029] In the process of rolling tea leaves, the amount of tea leaves put down is an important indicator. Too much or too little tea leaves will affect the rolling effect. The flow control valve 22 designed in the utility model can control the amount of tea leaves rolled to ensure the best rolling effect.
[0030] like Figure 2 and Figure 3 As shown, further, a plurality of rollers 52 are arranged to rotate inside the rotating drum 5, and the rotating drum 5 is arranged in the kneading cavity 53. The rollers 52 designed here can increase the kneading contact area of the tea leaves as much as possible, ensure that the tea leaves are kneaded as evenly as possible, and ensure the quality requirements of kneading; and the rollers 52 can rotate, which can reduce the sticking of the tea leaves to a certain extent. When the rotating drum 5 rotates and kneads, the rollers 52 will rotate relatively to a certain extent, increase the kneading effect, and the tea leaves are less likely to stick to the inner wall of the kneading cavity 53.
[0031] Furthermore, the roller 52 is set as a conical inclined surface, and the diameter of the upper section of the roller 52 is smaller than that of the lower section. The roller 52 designed in this way can realize tea kneading under different pressures to a certain extent. First, the initial tea leaves enter the kneading cavity 53 through the tea inlet cavity 41. Since the diameter of the upper part of the roller 52 is smaller, the space of the kneading cavity 53 is relatively larger, and the tea leaves just put down are loose and the required kneading pressure is smaller, which can meet the requirement of small pressure when the tea leaves are initially kneaded; while the rotating drum 5 rotates to realize kneading, the tea leaves become softer and the volume becomes smaller, and the kneaded tea leaves slowly reach the lower part of the roller 52. Since the diameter of the lower half of the roller is larger, the relative kneading cavity space is smaller, the pressure of the tea leaves in this part is greater, and the kneading force is relatively greater. Such a design can make the kneading of the tea leaves excessive, and the pressure gradually increases from small to large, which meets the process requirements of tea kneading and ensures the quality of tea kneading.
[0032] The crank-rocker mechanism 3 includes a first motor 31, a crank 32, an intermediate connecting rod 33, a rocker 34 and a piston rod 35. The first motor 31 is fixedly connected to the crank 32, the other end of the crank 32 is rotatably connected to the intermediate connecting rod 33, the other end of the intermediate connecting rod 33 is rotatably connected to the rocker 34, the other end of the rocker 34 is rotatably connected to the inner wall of the frame 1, one end of the rocker 34 is rotatably connected to the piston rod 35, and the other end of the piston rod 35 is rotatably connected to the piston 36. Such a design controls the movement of the crank-rocker mechanism 3 through the first motor 31, and finally realizes the reciprocating movement of the piston 36. The design is reasonable and easy to realize, and the secondary rolling of the tea leaves is realized through the movement of the piston 36.
[0033] Furthermore, a conical first magnet 361 is provided at the bottom of the piston 36; a matching conical mouth is provided at the bottom of the piston cylinder 4, and a retractable conical second magnet 45 is connected to the conical mouth through an elastic member. In the process of tea rolling, general machines can only achieve rolling mechanically, and uneven rolling leads to serious quality problems of tea. The conical first magnet 361 and the second magnet 45 designed here, when the piston 36 slides down, the first magnet 361 approaches the second magnet 45, and the two attract each other to achieve tea rolling; when the piston 36 moves up, the first magnet 361 drives the second magnet 45 to move up, so that the tea on the second magnet 45 is driven to move up, and after reaching a certain height, under the influence of the pulling force, the second magnet 45 is separated from the first magnet 361 and returns to the bottom of the piston cylinder 4, and due to inertia, the tea vibrates and flips. Such a design can ensure that the tea can be flipped every time the piston 36 is pressed down and rolled up, thereby ensuring the uniformity of tea rolling and further improving the quality of tea rolling.
[0034] The driving mechanism 6 includes a second motor 61, a large gear 63, a small gear 62 and a rotating shaft 64. The second motor 61 is installed on the motor mounting frame 12. The second motor 61 is connected to the small gear 62. The small gear 62 is meshed with the large gear 63. The large gear 63 is arranged on the rotating shaft 64. One end of the rotating shaft 64 is fixedly connected to the rotating drum 5. The other end of the rotating shaft 64 is rotatably connected to the mounting base 13 through the third bearing 65. A central through hole 641 is arranged inside the rotating shaft 64. The central through hole 641 is connected to the piston cavity 42 of the piston cylinder 4. The driving mechanism 6 designed in the utility model is driven by the second motor 61, and finally drives the rotating drum 5 to rotate through the gear reduction, thereby realizing the basic requirements of rolling. The rolled tea leaves are finally transferred from the piston cavity 42 through the pressure control valve 46 to the central through hole 641, and finally go out from the tea outlet 131.
[0035] Furthermore, the piston cylinder 4 includes an inner wall surface 43 and an outer wall surface 44, and a plurality of through holes 431 are evenly arranged on the inner wall surface 43, and the outer wall surface 44 is set as a breathable filter surface. Such a design can further ensure that the rolled tea leaves will not get sticky. When the piston 36 is pressed down, the airflow inside the cavity of the piston 36 reaches the outer wall surface 44 through the through hole 431, and the compressed rapid airflow is ejected through the filter surface, and the tea leaves stuck to the outer wall surface 44 of the piston cylinder 4 will be blown off. Such a design can not only ensure the cleanliness of the rolling cavity 53 and ensure that the rolled tea leaves are not sticky, but also make the rolling process of the tea leaves smoother and less prone to blockage, thereby ensuring the quality and efficiency of the tea rolling.
[0036] Working principle:
[0037] The tea leaves to be rolled are put into the conical discharge funnel 2, and the quantity and speed of the tea leaves put into the tea leaves are controlled by the flow control valve 22. The tea leaves enter the tea inlet cavity 41 from the first channel 21, and finally reach the rolling cavity 53. The tea leaves entering the rolling cavity 53 are driven by the second motor 61 to realize rotation rolling, and the relative extrusion rolling of the drum 52, and the tea leaves are gradually rolled and dropped from the rolling cavity 53 with a larger space at the upper end of the drum 52 to the rolling cavity 53 with a smaller space at the lower end of the drum 52, and the pressure is increased, and finally rolled into softer and smaller tea leaves, and reach the piston cavity 42 from the first outlet 432. The tea leaves reaching the piston cavity 42 are driven by the first motor 31 to press down the piston 36 to realize secondary rolling, and the tea leaves are turned over by the mutual position of the first magnet 361 at the bottom of the piston 36 and the retractable second magnet 45 to ensure the uniformity of rolling. When the tea leaves inside the piston cylinder 4 are small, the kneading pressure is small. When the tea leaves entering the piston 36 cavity from the kneading cavity 53 increase, the pressure of the piston 36 increases, and the kneading pressure increases. When the kneading pressure increases to a set value, the pressure control valve 46 opens, and the kneaded tea leaves are dropped to the tea outlet 131 through the center through hole 641.
[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
