Description

Technical Field

[0001] The present invention belongs to the technical field of tea processing equipment, and particularly relates to a tea rolling machine. Background Art

[0002] Except for traditional white tea, for teas such as green tea, black tea, oolong tea, and dark tea, rolling is one of the important technological processes in their processing. Through rolling, the shape of the tea leaves can become more beautiful, improving the appearance quality of the tea. At the same time, rolling can also make the aroma substances in the tea leaves dissolve better in the tea soup, making the aroma of the tea soup more intense.

[0003] Except for pure hand-made tea, the rolling process is generally completed using a tea rolling machine. Classified according to the rolling structure, the rolling machines on the market can be roughly divided into rod-type rolling machines, drum-type rolling machines, and the most commonly used disk-type rolling machines. Since rolling is an extremely time-consuming process in the tea processing flow, in the tea processing production line of a modern tea factory, a combined rolling system usually composed of 4 - 8 rolling machines, supplemented by a tea feeding conveying system, a tea discharging conveying system, a PLC control system, etc. is usually used.

[0004] Currently, in modern large-scale tea production enterprises, for the tea rolling process, if a combined rolling system composed of disk-type rolling machines is used, there will inevitably be problems such as large equipment size, large floor area, high cost, complex control, and high failure rate. If rod-type rolling machines or drum-type rolling machines are used, although the efficiency can be improved and the cost can be reduced, the rolling effect and the quality of the tea are difficult to reach the level of disk-type rolling machines. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a tea rolling machine.

[0006] The technical solution adopted to solve the above technical problem is:

[0007] A tea rolling machine includes a frame, a reduction motor, a rolling disk, and a plurality of rolling barrels. The rolling disk is arranged on the frame, the reduction motor is arranged at the bottom of the rolling disk, a plurality of the rolling barrels are all arranged above the rolling disk, the reduction motor is arranged directly below the central position of the rolling disk, the output end of the reduction motor passes through the side wall of the rolling disk and is fixedly connected with a central shaft, the other end of the central shaft is fixedly provided with a central wheel, a planet carrier is arranged on the frame, the central wheel is rotationally connected with the bottom of the planet carrier, and a plurality of planet wheels are also rotationally connected with the bottom of the planet carrier, and each planet wheel meshes with the central wheel;

[0008] A kneading cover is provided at the bottom of each planetary gear. The kneading cover is arranged on the kneading barrel. An inlet for tea is provided on the side wall of the kneading barrel. A number of kneading ribs are fixedly arranged on the kneading plate. An outlet for tea is provided on the top of the kneading plate.

[0009] Through the above technical solution, the present invention can accommodate a number of kneading barrels of a tall combined kneading system in a very limited space, with a compact structure and low cost, and still based on the design of a disk kneading system, ensuring the kneading effect.

[0010] Further, a protective shell is fixedly arranged on the top of the planetary carrier. The protective shell is sleeved outside the central shaft. The height of the protective shell is less than the distance between the kneading plate and the central gear.

[0011] Through the above technical solution, the setting of the protective shell can prevent the tea greens from affecting the rotation of the central shaft. When the tea greens are kneaded by the kneading barrel, they will be blocked outside the protective shell, and the protective shell will not affect the rotation of the central gear.

[0012] Further, a number of electric push rods are arranged on the top of the planetary carrier. The output end of the electric push rod is fixedly connected with a sliding rod. The sliding rod passes through the side wall of the planetary carrier and is fixedly connected with the side wall of the kneading cover.

[0013] Through the above technical solution, by driving the electric push rod, the kneading cover and the kneading barrel can be lifted and lowered together, thus facilitating the staff to clean the kneading plate.

[0014] Further, a guide rail is arranged on the side wall of the kneading plate. A support ring is rotatably connected to the guide rail. The side wall of the support ring abuts against the side wall of the kneading barrel.

[0015] Through the above technical solution, the setting of the support ring and the guide rail can prevent foreign matters from entering the kneading plate, thus ensuring the purity of the tea greens during kneading.

[0016] Further, the outlet for tea is eccentrically arranged on the top of the kneading plate. The outlet for tea is located between two adjacent kneading ribs. A baffle is arranged in the outlet for tea. The baffle is flush with the height of the kneading plate.

[0017] Through the above technical solution, the baffle is flush with the height of the kneading plate, so that when the kneading barrel kneads the tea greens, no tea greens will be blocked at the position of the outlet for tea, thus preventing the waste of tea greens during the kneading process and further reducing the ineffective loss during the kneading process.

[0018] Further, a rotating motor is installed at the bottom of the kneading plate. The output end of the rotating motor is fixedly provided with a rotating rod. The rotating rod is fixedly connected with the bottom of the baffle.

[0019] Through the above technical solution, the driving rotating motor can open or close the tea outlet. When the tea greens are being kneaded, the baffle will normally block at the position of the tea outlet to ensure that the tea greens are kneaded normally. When the kneading is completed, the rotating motor can drive the baffle to open the tea outlet, facilitating the falling of the kneaded tea greens.

[0020] Furthermore, the thickness of the planetary gear is greater than that of the central gear, and the several kneading barrels do not contact each other, nor do the several kneading barrels contact the protective shell.

[0021] Through the above technical solution, since the diameter of the kneading barrel is larger than that of the planetary gear, in order to prevent collisions between the kneading barrels, a certain space needs to be reserved at the bottom of the central gear to facilitate the revolution and rotation of the kneading barrels. At the same time, in order to prevent the kneading barrels from colliding with the protective shell, sufficient space also needs to be reserved in advance. Also, in order to better knead the tea greens and avoid the tea greens sticking to the protective shell.

[0022] Furthermore, the kneading plate is disc-shaped, and the cross-section of the kneading rib is arc-shaped.

[0023] Through the above technical solution, the shape, curvature and height of the kneading rib will affect the kneading quality and efficiency. The kneading rib settings in different kneading machines will be slightly different, and the kneading ribs corresponding to different teas are also different, which can be adjusted by different manufacturers according to the actual situation.

[0024] Through the above technical solution, the beneficial effects of the present invention are as follows:

[0025] (1) The present invention can accommodate several kneading barrels of a tall combined kneading system in a very limited space. A single kneading plate can simultaneously accommodate multiple kneading barrels to knead tea leaves. The structure is compact, the cost is low, and it is still designed based on the disk-type kneading system, ensuring the kneading effect and making the entire kneading process more efficient;

[0026] (2) The present invention uses the kneading ribs distributed on the annular kneading plate to cause the tea greens in the kneading barrel to tumble up and down. During the rotation, revolution and tumbling of the tea greens, the tea green cell tissue is partially damaged and volatile substances are released during the mutual friction between the tea greens and the barrel wall, between the tea greens and the kneading ribs, and between the tea greens. At the same time, it promotes the curling and compacting of the tea greens, thereby improving the quality of the tea leaves;

[0027] (3) The tea inlet provided on the side wall of the kneading barrel can be connected to the tea green pneumatic conveyor, and a mesh belt conveyor can also be provided at the position of the tea outlet on the side wall of the kneading plate, making the entire tea green kneading system more intelligent and automated. Moreover, since there are multiple kneading barrels on the kneading plate to knead the tea greens simultaneously, the kneading efficiency is improved. Description of the Drawings

Detailed implementation manners

[0034] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] As Figures 1-5 shown, this embodiment provides a tea rolling machine, which includes a frame 1, a reduction motor 2, a rolling disc 3 and a plurality of rolling barrels 4. The rolling disc 3 is arranged on the frame 1, the reduction motor 2 is arranged at the bottom of the rolling disc 3, and a plurality of rolling barrels 4 are all arranged above the rolling disc 3. The rolling barrel 4 is a hollow round barrel. The reduction motor 2 is arranged directly below the center position of the rolling disc 3. The output end of the reduction motor 2 passes through the side wall of the rolling disc 3 and is fixedly connected to a central shaft 5. A protective housing 13 is fixedly arranged on the top of the rolling disc 3. The protective housing 13 is sleeved outside the central shaft 5. The height of the protective housing 13 is less than the distance between the rolling disc 3 and the sun gear 6. The setting of the protective housing 13 can prevent the tea green from affecting the rotation of the central shaft 5, and the protective housing 13 will not affect the rotation of the sun gear 6 either.

[0036] The thickness of the planetary gear 8 is greater than that of the central gear 6. The several kneading barrels 4 do not contact each other, and the several kneading barrels 4 also do not contact the protective shell 13. Since the diameter of the kneading barrel 4 is larger than that of the planetary gear 8, in order to prevent collisions between the kneading barrels 4, a section of space needs to be reserved at the bottom of the central gear 6 to facilitate the revolution and rotation of the kneading barrel 4. At the same time, in order to prevent the kneading barrel 4 from colliding with the protective shell 13, sufficient space also needs to be reserved in advance. At the same time, in order to better knead the tea greens and avoid the tea greens sticking to the protective shell 13.

[0037] At the other end of the central shaft 5, a central gear 6 is fixedly arranged. A planetary carrier 7 is arranged on the frame 1. Although it is not clearly marked in the figure, the planetary carrier 7 is arranged on the frame 1. Therefore, the planetary carrier 7 will not easily change its position and can also play a limiting role on the central gear 6 and the planetary gears 8. The central gear 6 is rotatably connected to the bottom of the planetary carrier 7. Several planetary gears 8 are also rotatably connected to the bottom of the planetary carrier 7. Each planetary gear 8 meshes with the central gear 6. Several electric push rods 14 are arranged on the top of the planetary carrier 7. The output end of the electric push rod 14 is fixedly connected to a sliding rod 15. The sliding rod 15 passes through the side wall of the planetary carrier 7 and is fixedly connected to the side wall of the kneading cover 9. By driving the electric push rod 14, the kneading cover 9 and the kneading barrel 4 can be lifted and lowered together, which is convenient for the staff to clean the kneading plate 3.

[0038] A kneading cover 9 is arranged at the bottom of each planetary gear 8. The kneading cover 9 is arranged on the kneading barrel 4. A guide rail 16 is arranged on the side wall of the kneading plate 3. A support ring 17 is rotatably connected to the guide rail 16. The side wall of the support ring 17 abuts against the side wall of the kneading barrel 4. The arrangement of the support ring 17 and the guide rail 16 can prevent foreign objects from entering the kneading plate 3, thereby ensuring the purity of the tea greens when being kneaded.

[0039] An inlet 10 for tea is provided on the side wall of the kneading barrel 4. Several kneading ribs 11 are fixedly arranged on the kneading plate 3. The kneading plate 3 is disc-shaped. The cross-section of the kneading rib 11 is arc-shaped. The shape, curvature and height of the kneading rib 11 will affect the kneading quality and efficiency. The kneading ribs 11 in different kneading machines will be slightly different, and the kneading ribs 11 corresponding to different teas are also different, which can be adjusted by different manufacturers according to the actual situation.

[0040] The top of the rolling disk 3 is provided with a tea outlet 12. A mesh belt conveyor can be arranged below the frame 1. The rolled tea greens can directly fall from the tea outlet 12 onto the mesh belt conveyor, thereby making the whole system more automated and further improving the rolling efficiency. The tea outlet 12 is eccentrically arranged at the top of the rolling disk 3. The tea outlet 12 is located between two adjacent rolling ribs 11. A baffle 18 is arranged in the tea outlet 12. The baffle 18 is flush with the height of the rolling disk 3. Thus, when the rolling barrel 4 rolls the tea greens, no tea greens will be blocked at the position of the tea outlet 12. A rotating motor 19 is installed at the bottom of the rolling disk 3. The output end of the rotating motor 19 is fixedly provided with a rotating rod 20. The rotating rod 20 is fixedly connected to the bottom of the baffle 18. The rotating motor 19 can open or close the tea outlet 12.

[0041] The working principle of this embodiment is as follows. First, use the tea air conveyor to send the tea greens into the rolling barrel 4 through the tea inlet 10 at the upper part of the rolling barrel 4. Then start the reduction motor 2. The reduction motor 2 will drive the central shaft 5 to rotate, and then the central wheel 6 at the other end of the central shaft 5 will rotate. The planetary gear 8 meshing with the central wheel 6 will also rotate accordingly. The rolling cover 9 arranged at the bottom of the planetary gear 8 and the rolling barrel 4 will drive the tea greens to rotate together, so that the tea greens rotate on the rolling ribs 11 and the rolling disk 3, and the rolling ribs 11 distributed on the annular rolling disk 3 are used to make the tea greens in the rolling barrel 4 tumble up and down. During the processes of the tea greens' self-rotation, revolution, and tumbling, when the tea greens rub against the barrel wall, the rolling ribs 11, and each other, the cell tissues of the tea greens are partially damaged and volatile substances are released. At the same time, the tea greens are curled and compacted. After the rolling is completed, with the help of the control system, the rotating motor 19 operates. The rotating motor 19 will drive the rotating rod 20 and the baffle 18 to rotate together, so as to facilitate the sequential tea discharging of each rolling barrel 4.

[0042] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
