Description

Technical Field

[0001] This invention relates to the field of tea rolling technology, and more specifically to an automatic tea rolling machine. Background Technology

[0002] Rolling is a step in tea processing, and most tea production processes involve this step. Rolling can be understood as two actions: kneading, which shapes the tea leaves into strips, and twisting, which breaks down the tea cells, squeezing out tea juice and allowing it to adhere to the surface of the tea strips, increasing viscosity and facilitating the shaping of the tea leaves. This method reduces the surface area of ​​the tea leaves, forming them into strips. There are two common methods: hand rolling and machine rolling. Currently, except for a small amount of high-quality teas that still retain hand rolling, most processing has been mechanized. Hand rolling is suitable for a small quantity of green tea or some other high-quality teas. The requirements for rolling are to start with light pressure, gradually increasing it, alternating between light and heavy pressure, and finally removing all pressure. Initially, no pressure is applied, allowing the tea leaves to roll along their veins into strips. Later, pressure is applied to break down the cells. Hand rolling is performed on a rolling table. During the process, the tea leaves are held in the palm of one or both hands and pushed forward on a rolling sheet, causing the tea clump to turn and rotate in the palm. Once a certain amount of clumps has formed, it is broken up once to prevent the processed leaves from clumping together. Mechanical kneading should avoid over-kneading to prevent reducing the number of tea infusions. Traditional eccentric kneading equipment is prone to over-kneading, which leads to a reduction in the number of tea infusions. Summary of the Invention

[0028] An automatic tea rolling machine, reference Figure 1 and 2 It includes a single-opening cover 11, the inner wall of the cover 11 is an annular wall, and the cover 11 is used to place tea leaves to be kneaded. Preferably, the tea leaves are pre-formed into a ball shape.

[0029] Furthermore, in combination Figure 3 It also includes a base 21 fixed to the ground, and a kneading component 44 disposed inside a housing 11. A shaft I 12 is fixed to the center inside the housing 11, and the axis of the housing 11 coincides with the axis of the shaft I 12. A base beam 22 is rotatably connected to the base 21, and the shaft I 12 is rotatably connected inside the base beam 22. A motor I 23 is fixed to the base 21, and the output shaft of the motor I 23 drives the base beam 22 to rotate through a pulley and belt assembly. A motor II 24 is fixed to the base 21, and the output shaft of the motor II 24 drives the shaft I 12 to rotate through a pulley and belt assembly. The rotation of the base beam 22 can change the circumferential position of the kneading component 44, so as to facilitate the insertion of tea leaves into the housing 11.

[0030] Furthermore, a linear reciprocating mechanism is installed on the base beam 22. The linear reciprocating mechanism adjusts the distance between the kneading component 44 and the bottom of the inner wall of the cover 11. When the kneading component 44 repeatedly rises and falls, it can repeatedly squeeze the tea leaves inside the cover 11. At the same time, the cover 11 is rotated, which drives the tea leaves to move circumferentially. Then, the tea leaves roll back to the bottom of the cover 11, i.e., the kneading area, by gravity, so as to generate lateral friction force. This, together with the repeated squeezing of the kneading component 44, achieves kneading.

[0031] Further reference Figure 4 The fixed end of the telescopic cylinder I 31 is fixedly connected to the base 21, and the movable end of the telescopic cylinder I 31 is fixedly connected to the baffle 32. The baffle 32 can block and open the inner wall of the opening of the cover 11 to prevent the kneaded tea leaves from falling out of the opening of the cover 11.

[0032] Combination Figure 4 Preferably, the baffle 32 is rotatably connected to a shaft II 33, and a pressure roller 34 is fixedly connected to the shaft II 33. More preferably, the pressure roller 34 is an air bladder that can be inflated and deflated by connecting an air pump and a pipeline. The diameter of the air bladder can be changed to compensate for the tea leaves that have fallen out of the kneading area. At the same time, when the air bladder contracts, the scattered tea leaves can roll back into the kneading area.

[0033] Preferred, combined Figures 5 to 8 The linear reciprocating mechanism includes an upper base frame 41 that is slidably connected to the base beam 22. The upper end of the upper base frame 41 includes two rods I that are slidably connected to the base beam 22. The upper base frame 41 also includes a frame with a straight groove fixed to the lower end of the two rods I, and a hollow columnar member fixed to the lower end of the frame with a straight groove.

[0034] Furthermore, the linear reciprocating mechanism also includes a middle base frame 42 slidably connected to the lower part of the upper base frame 41. The middle base frame 42 includes two rods II and a plate I fixed to the lower end of the two rods II. The two rods II are slidably connected to two hollow columnar members. The hollow columnar members are provided with vertical windows. The two rods II are fixed with keys, which are slidably connected to the windows. The hollow columnar members are provided with compression springs, and the upper and lower ends of the compression springs are in contact with the frame with straight slots and the top of the rods II, respectively.

[0035] Furthermore, the linear reciprocating mechanism also includes a lower base frame 43 slidably connected to the middle base frame 42. The lower base frame 43 includes two rods III and a plate II fixed to the lower end of the two rods III. The two rods III are slidably connected to the plate I. Preferably, multiple holes I are vertically distributed on the rods III, and holes II are provided on the plate I. When any hole I and hole II coincide, fasteners such as pins are inserted into them to fix the relative position of the lower base frame 43 and the middle base frame 42. The relative position can be changed, the purpose of which is to change the initial position of the kneading element 44, which is fixed to the lower end of the plate II.

[0036] The linear reciprocating mechanism also includes a motor III 51 fixed to the base beam 22. One end of a connecting rod 52 is fixed to the output shaft of the motor III 51, and the other end of the connecting rod 52 is rotatably connected to a lever 53. The lever 53 is inserted into a frame with a straight groove. When the motor III 51 is started, it drives the connecting rod 52 to rotate. The connecting rod 52 drives the lever 53 to repeatedly rise and fall. The lever 53 drives the frame with the straight groove to repeatedly rise and fall, so that the kneading element 44 repeatedly rises and falls. The pressure generated by the compression spring simulates hand kneading. The pressure increases gradually, and the initial pressure can be adjusted by changing the initial position of the kneading element 44.

[0037] Furthermore, the lower end of the kneading member 44 is provided with a protrusion I 441 in the middle, and a protrusion II 442 is provided on each of the left and right sides of the lower end of the kneading member 44. A recess 443 is formed between any protrusion II 442 and protrusion I 441. The protrusion II 442 is lower than the protrusion I 441. The lower ends of the protrusion II 442 and protrusion I 441 are arc end faces to form an M-shaped arc end face, which performs a wrapping kneading of the tea leaves. The pressure generated during kneading increases in the direction and the kneading is more uniform.

[0038] Furthermore, a fixed end of a telescopic cylinder II 61 is fixedly connected to the base beam 22, and a motor IV 62 is fixedly connected to the movable end of the telescopic cylinder II 61. The output shaft of the motor IV 62 is vertical, and a dispersing component 63 is fixedly connected to the output shaft of the motor IV 62. The dispersing component 63 includes a disc fixedly connected to the motor IV 62, and one or more columnar components fixedly connected to the eccentric position of the disc. Preferably, when the dispersing component 63 faces upward, the kneading component 44 faces downward. When the base beam 22 is rotated so that the dispersing component 63 faces downward, the telescopic cylinder II 61 is activated to drive the dispersing component 63 to descend and insert into the clump of tea leaves. The motor IV 62 is activated to drive the dispersing component 63 to rotate so that the tea leaves are dispersed, so as to facilitate re-kneading into a clump, avoiding excessive kneading of the outer tea leaves and insufficient kneading of the clump of tea leaves.
