Description

Technical Field

[0001] The utility model relates to the technical field of tea rolling, in particular to a tea rolling machine for tea production. Background Art

[0002] Tea rolling, as a key link in the initial processing of tea, plays a vital role in shaping the quality of tea. The rolling process can not only roll up the tea leaves and reduce their volume, laying a solid foundation for the subsequent frying and drying into strips, but also properly destroy the leaf tissue, promote material transformation, and enhance the aroma and taste of the tea. Different teas require different rolling strengths. Green tea generally focuses on light rolling, black tea focuses on heavy rolling, and oolong tea is different from black tea and green tea in rolling. It mainly requires alternating hot and cold rolling, focusing on shaping.

[0003] In the prior art, the existing tea rolling machine is mainly equipped with a lotus seat, a transmission group, and a cloth rolling rod. The lotus seat is equipped with several lotus leaves, which are driven by the transmission group to open and close the lotus leaves to roll and compress the tea leaves. Another driving motor drives the lotus seat to rotate, and cooperates with the cloth rolling rod to automatically roll the cloth bag into a knot, so that the accommodating space of the cloth bag is gradually reduced, thereby achieving the function of double rolling of the tea leaves and reducing the volume.

[0004] The existing tea rolling machine mainly focuses on rolling tea leaves, and generally works in a well-ventilated place. At the same time, the pressure, that is, the rolling force, can be controlled. However, it is not convenient to control the temperature when rolling oolong tea leaves, thereby reducing the quality of the oolong tea leaves after rolling. Utility Model Content

[0024] Reference Figure 1-Figure 3The utility model discloses a tea rolling machine for tea production, comprising a bottom cover 1 and a lotus platform 2, a heat conducting pipe 3 is fixedly connected to the bottom side of the lotus platform 2, an air inlet pipe 4 is connected to the bottom side of the heat conducting pipe 3, the top of the air inlet pipe 4 is communicated with the heat conducting pipe 3, a switching pipe 5 is fixedly connected to the bottom end of the air inlet pipe 4, a switching sheet 6 is fixedly connected to the inner side wall of the switching pipe 5, an air inlet hole 7 is opened on the switching sheet 6, a switching member 8 is arranged on the bottom side of the switching sheet 6, and a driving member 9 is arranged on the inner peripheral wall of the bottom cover 1.

[0025] In this embodiment, the hot air blower and the cold air blower are connected to the switching member 8. When the oolong tea leaves are rolled, the hot air blower and the cold air blower are started at the same time. At this time, the hot air will enter the switching tube 5 through the air inlet 7, and then enter the air inlet pipe 4 through the switching tube 5, and finally enter the heat conducting tube 3, so as to control the temperature of the lotus platform 2. With the continuous driving of the driving member 9, the temperature in the heat conducting tube 3 will be switched from hot air to cold air through the switching member 8. Therefore, the temperature in the heat conducting tube 3 will gradually rise and then switch to gradually fall, so that the oolong tea leaves can be switched between hot and cold when being rolled on the lotus platform 2, thereby avoiding the deterioration of the rolling quality of the oolong tea leaves due to being in a ventilated working environment for a long time.

[0026] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the switching member 8 includes a cover tube 10 , which is rotatably connected to the bottom side of the switching piece 6 , and a cold air pipe 11 and a hot air pipe 12 are fixedly connected to the inner peripheral wall of the cover tube 10 .

[0027] In this embodiment, the cover pipe 10 is used to protect the hot air pipe 12 and the cold air pipe 11, wherein the cold air pipe 11 and the hot air pipe 12 are both connected to a pressure relief valve when in use to prevent the hot air blower or the cold air blower from being burned out due to excessive air pressure when one of the two is blocked. The cold air pipe 11 and the hot air pipe 12 are both flexible pipes to prevent them from being broken after switching.

[0028] In a further preferred embodiment of the present invention, Figure 2-3 As shown, a positioning ring 13 is fixedly connected to the outer peripheral wall of the cover tube 10 , a torsion spring 14 is fixedly connected between the top side of the positioning ring 13 and the bottom side of the switching tube 5 , and a switching plate 15 is fixedly connected to the outer peripheral wall of the positioning ring 13 .

[0029] In this embodiment, in the initial cold air pipe 11 and hot air pipe 12, the hot air pipe 12 is connected to the hot air hole, and the driving member 9 provided therein will push the switching plate 15 when rotating, and then drive the positioning ring 13 to rotate through the switching plate 15, and the positioning ring 13 will drive the cover tube 10 to rotate, thereby driving the internal hot air pipe 12 and the cold air pipe 11 to rotate synchronously, so that the cold air pipe 11 switches to the air inlet 7, wherein sealing rings need to be installed at the moving paths of the ends of the hot air pipe 12 and the cold air pipe 11, so that they can be sealed after being separated from the air inlet 7, and the torsion spring 14 provided in addition will release the limit on the switching plate 15 under the continuous drive of the driving member 9, so that the reaction force of the torsion spring 14 drives the cover tube 10 to rotate to the initial position, thereby achieving the effect of switching again, so that the lotus platform 2 can perform the effect of switching between cold and hot by inputting cold air and hot air into the heat conducting pipe 3.

[0030] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the driving member 9 includes a driving motor 16, which is fixedly mounted on the outer peripheral wall of the bottom cover 1. The output shaft of the driving motor 16 extends into the bottom cover 1 and is connected to a driving bevel gear 17. A transmission bevel gear 18 is rotatably connected to the inner peripheral wall of the bottom cover 1. The transmission bevel gear 18 is meshed with the driving bevel gear 17. A gap is left between the transmission bevel gear 18 and the switching plate 15. An arc rod 20 is fixedly connected to the inner peripheral wall of the transmission bevel gear 18. The switching plate 15 is on the rotation path of the arc rod 20.

[0031] In this embodiment, the driving member 9 is driven by the driving motor 16 to drive the driving bevel gear 17 to rotate, and then the driving bevel gear 17 drives the transmission bevel gear 18 to rotate, and then the arc rod 20 on the inner wall of the transmission bevel gear 18 will rotate, and the end of the arc rod 20 moves to the switching plate 15 and then pushes the switching plate 15 to move, and the switching plate 15 is fixedly connected with the positioning ring 13, and the positioning ring 13 is fixedly installed on the cover tube 10, and the cover tube 10 is rotatably installed on the bottom side of the switching piece 6, so as to drive the rotation of the cover tube 10 and drive The torsion spring 14 twists, and the switching plate 15 rotates accordingly. The switching plate 15 is on the moving path of the arc rod 20. Therefore, when the arc rod 20 continues to rotate, it will keep the switching plate 15 in the moved position, and at the same time achieve the effect of driving the hot air pipe 12 and the cold air pipe 11 to rotate and switch. After the cold air pipe 11 is switched and connected, the continuous rotation of the arc rod 20 will be separated from the rotation of the switching plate 15, and then the torsion spring 14 drives the positioning ring 13 and the cover pipe 10 to rotate, so that the hot air pipe 12 is reconnected to the air inlet 7, achieving the effect of switching again.
