Description

Technical Field

[0001] The invention relates to the technical field of tea rolling, and more particularly to a rolling machine capable of self-regulating rolling pressure based on tea temperature. Background Art

[0002] The rolling machine is a key equipment in the tea processing process. Its working principle is to use power to drive the rolling cylinder to rotate relative to the rolling plate, and at the same time use the pressure mechanism to apply appropriate pressure to the tea in the rolling cylinder, so that the tea leaves are constantly rolling, rubbing and squeezing between the rolling cylinder and the rolling plate, thereby achieving the purpose of breaking the tea cells and curling them into strips. This process plays an extremely important role in shaping the appearance of tea and releasing and transforming the internal components.

[0003] However, in the prior art, due to the continuous tumbling and friction of the tea leaves in the kneading cylinder, the temperature will continue to rise. If the temperature is too high, the activity of the substances in the cells will be enhanced, and excessive pressure will cause excessive cell fragmentation, resulting in excessive tea juice, affecting subsequent processing. By adjusting the pressure through temperature, the degree of cell fragmentation can be accurately controlled to achieve the best kneading effect. In addition, due to the uneven accumulation of tea leaves in the kneading cylinder, some tea leaves cannot fully contact the kneading plate and the kneading cylinder, resulting in uneven kneading of the tea leaves after kneading, uneven thickness of the tea leaves, and inconsistent degree of crushing.

[0040] When in use, the tea leaves are placed in the kneading cylinder 3, and the second motor 34 is started. The second motor 34 drives the pressure cover 4 to move downward through the screw to pressurize the tea leaves. When the pressure reaches the pressure required for kneading the tea leaves, the second motor 34 is turned off, and the first motor 11 is started. The first motor 11 drives the second rotating shaft 12 to rotate through the belt transmission connection and the coupling. The second rotating shaft 12 drives the drum frame 31 to rotate through the connecting rod, so that the drum frame 31 drives the third rotating shaft 13 to rotate on the base 1 through the connecting rod, so that the kneading cylinder 3 rotates on the kneading plate 2, so that the tea leaves are continuously rolled, rubbed and squeezed between the kneading cylinder 3 and the kneading plate 2. As the volume of the tea leaves continues to decrease during the kneading process, when the pressure sensor on the pressure cover 4 detects When the pressure is lower than the threshold, the second motor 34 is started by the controller 48 to press the pressure cover 4 down to increase the pressure. When the temperature sensor detects that the kneading temperature of the tea leaves in the kneading cylinder 3 is higher than the threshold, the second motor 34 is started by the controller 48 to drive the pressure cover 4 to move upward, thereby reducing the pressure and increasing the space between the pressure cover 4 and the kneading plate 2. When the temperature sensor detects that the kneading temperature of the tea leaves in the kneading cylinder 3 is lower than the threshold, the second motor 34 is started by the controller 48 to drive the pressure cover 4 to move downward to increase the pressure. The temperature of the tea leaves is detected by the temperature sensor to adjust the pressure on the tea leaves during kneading, thereby improving the influence of friction on the temperature of the tea leaves and preventing the problem of low tea rolling yield due to temperature discomfort during kneading.

[0041] Example 2

[0042] In actual use, it was found that due to the uneven accumulation of tea leaves in the kneading cylinder 3, some tea leaves could not fully contact the kneading plate 2 and the kneading cylinder 3, resulting in uneven kneading of the tea leaves, uneven thickness of the tea leaves, and inconsistent degree of crushing. Further improvements were made on the basis of the above embodiments.

[0043] On the basis of the above embodiment, when in use, the first motor 11 is started to make the drum frame 31 drive the kneading drum 3 to rotate. At the same time, the first motor 11 drives the first rotating shaft 53 to rotate through the belt transmission, so that the first rotating shaft 53 drives the magnet 521 to rotate through the magnetic disk 52. When the magnet 521 rotates to one end of the third air cylinder 51, the first piston rod 512 slides in the direction of the first rotating shaft 53 due to the attraction of the magnet 521, so that the third piston plate 511 slides in the direction of the first rotating shaft 53, and at the same time, the first elastic member 513 is compressed, and the gas inside the third air cylinder 51 enters the first air cylinder 42 through the third through hole 514 and the first through hole 44, so that the first piston plate 43 inside the first air cylinder 42 moves downward, so that the gas at the lower end of the first air cylinder 42 is squeezed into the first airbag 41, so that the first airbag 41 and the second airbag 21 expand. When the magnet 521 no longer attracts the first piston rod 512, at this time, the first elastic member 5 13 expansion makes the third piston plate 511 move in the opposite direction, thereby causing the first air bag 41 and the second air bag 21 to contract. When the magnet 521 rotates to one end of the fourth air cylinder 54, the second piston rod 542 drives the fourth piston plate 541 to move toward the first rotating shaft 53 due to the gravitational force of the magnet 521, thereby compressing the second elastic member 543 and allowing the gas to enter the second air bag 21 through the fourth through hole 544 and the second through hole 24, thereby causing the second air bag 21 to expand. When the magnet 521 no longer attracts the second piston rod 542, the second air bag 21 contracts. The magnetic disk 52 continuously rotates, causing the first air bag 41 and the second air bag 21 to alternately expand and contract, thereby causing the tea leaves to continuously flip over inside the kneading cylinder 3, thereby improving the kneading efficiency and allowing the tea leaves inside the kneading cylinder 3 to evenly contact the kneading disk 2, thereby preventing the tea leaves in the kneading cylinder 3 from being unevenly kneaded, uneven thickness of the tea leaves, and inconsistent degree of crushing after being kneaded.

[0044] Example 3

[0045] In actual use, it is found that when the first airbag 41 and the second airbag 21 expand and contract, the internal space of the kneading cylinder 3 changes continuously, which easily leads to uneven pressure on the tea leaves and causes the second motor 34 to start repeatedly. Further improvements are made on the basis of the above embodiment.

[0046] When the third piston plate 511 moves in the direction of the first rotating shaft 53, the third piston plate 511 no longer presses the switch inside the third gas cylinder 51, and the stop valve at the fifth through hole 515 is opened. At this time, the internal gas of the chamber of the third gas cylinder 51 on the side close to the first rotating shaft 53 is squeezed to the first gas cylinder 42, and at the same time, the internal gas of the fifth gas cylinder 47 enters the other side chamber of the third gas cylinder 51 through the seventh through hole 471 and the fifth through hole 515, so that the spring inside the fifth gas cylinder 47 is stretched, and at the same time, the fifth piston plate 46 drives the pressure cover 4 to move upward, so that the air inside the kneading cylinder 3 is When the third piston plate 511 moves in the direction away from the first rotating shaft 53 due to the expansion of the first elastic member 513, the gas returns to the fifth gas cylinder 47, and the spring inside the fifth gas cylinder 47 recovers, so that the pressure cover 4 moves downward, thereby reducing the internal space of the kneading cylinder 3. When the third piston plate 511 moves to the limit position, the third piston plate 511 presses the switch inside the third gas cylinder 51 again, and the stop valve at the fifth through hole 515 is closed. When the fourth piston plate 541 moves in the direction of the first rotating shaft 53, the fourth piston plate 541 no longer presses the fourth gas cylinder 5 4, the stop valve at the sixth through hole 545 is opened, and the internal gas of the chamber of the fourth gas cylinder 54 close to the first rotating shaft 53 is squeezed to the second gas cylinder 22, and the internal gas of the fifth gas cylinder 47 enters the chamber of the fourth gas cylinder 54 away from the first rotating shaft 53 through the eighth through hole 472 and the sixth through hole 545, so that the internal spring of the fifth gas cylinder 47 is stretched, and the fifth piston plate 46 drives the pressure cover 4 to move upward. When the fourth piston plate 541 moves in the direction away from the first rotating shaft 53, the gas re-enters the fifth gas cylinder 47, and the gas in the fifth gas cylinder 47 The spring is restored, and at the same time, the fifth piston plate 46 drives the pressure cover 4 to move downward. When the fourth piston plate 541 moves to the limit position, the fourth piston plate 541 presses the internal switch of the fourth air cylinder 54 again, and the stop valve at the sixth through hole 545 is closed to ensure that when the first air bag 41 and the second air bag 21 expand, the pressure cover 4 moves upward to increase the internal space of the kneading cylinder 3. When the first air bag 41 and the second air bag 21 shrink, the pressure cover 4 moves downward to restore its original state, preventing the internal space of the kneading cylinder 3 from constantly changing, which may easily lead to uneven pressure on the tea leaves and cause the problem of repeated starting of the second motor 34.
