[0061] Please refer to Figures 1-11The application also provides a rolling device applied to the green tea production process, which comprises a rolling disc 100, a rolling cylinder 200 movably arranged on the top of the rolling disc 100, a driving assembly 300 for driving the rolling cylinder 200 to rotate around the central axis of the rolling disc 100, a sealing cover 400 movably arranged in the rolling cylinder 200, and a lifting assembly 500 for driving the sealing cover 400 to move. In use, after the sealing cover 400 moves downward to contact the tea leaves in the rolling cylinder 200 under the driving of the lifting assembly 500, the driving assembly 300 is started, and the rolling cylinder 200 rotates on the rolling disc 100 along the central axis thereof under the driving of the driving assembly 300 to roll and twist the tea leaves. The above detailed process and principle are conventional technologies, and thus will not be described in detail here.

[0062] Although the tea leaves can be automatically discharged from the center of the rolling disc 100 during the movement of the rolling cylinder 200 after the rolling and twisting is completed, the tea leaves adhered to the rolling disc 100 during the rolling and twisting process cannot be completely cleaned by the movement of the rolling cylinder 200, and if the tea leaves on the rolling disc 100 are not cleaned, different quality tea leaves will be present in the next rolling and twisting process, and if the tea leaves of different varieties are rolled and twisted twice, the taste will be conflicted. In the conventional technology, the tea leaves on the rolling disc 100 are manually cleaned, which can solve the problem, but in the automatic production process of the green tea in a flow line, the manual cleaning increases the labor intensity of the operators, reduces the rolling and twisting efficiency, and increases the rolling and twisting cost of the tea leaves.

[0063] Therefore, the rolling disc 100 is improved in structure in the technical solution, the residual tea leaves on the rolling disc 100 can be automatically cleaned after the rolling and twisting is completed, the labor intensity of the operators is reduced, the rolling and twisting efficiency is improved, and the rolling and twisting cost of the tea leaves is reduced without affecting the rolling and twisting effect of the green tea. Figures 3-4 As shown in the figure, the rolling disc 100 comprises a rolling disc 110 and a surrounding plate assembly 120, the rolling disc 110 and the surrounding plate assembly 120 jointly form a rolling groove 130 in the shape of a column, a discharge port 140 is arranged at the center of the rolling disc 110, a blocking cover assembly 150 is arranged at the discharge port 140, and a heating module is arranged in the rolling disc 110. During the rolling and twisting process, the discharge port 140 is blocked by the blocking cover assembly 150, the rolling cylinder 200 drives the tea leaves to move in the rolling groove 130 during the rotation to perform the rolling and twisting operation, and after the rolling and twisting is completed, the blocking cover assembly 150 unblocks the discharge port, and at this time, the tea leaves are discharged from the discharge port 140 during the rotation of the rolling cylinder 200.

[0064] Specifically, as shown in the figure, the rolling disc 100 comprises a rolling disc 110 and a surrounding plate assembly 120, the rolling disc 110 and the surrounding plate assembly 120 jointly form a rolling groove 130 in the shape of a column, a discharge port 140 is arranged at the center of the rolling disc 110, a blocking cover assembly 150 is arranged at the discharge port 140, and a heating module is arranged in the rolling disc 110. During the rolling and twisting process, the discharge port 140 is blocked by the blocking cover assembly 150, the rolling cylinder 200 drives the tea leaves to move in the rolling groove 130 during the rotation to perform the rolling and twisting operation, and after the rolling and twisting is completed, the blocking cover assembly 150 unblocks the discharge port, and at this time, the tea leaves are discharged from the discharge port 140 during the rotation of the rolling cylinder 200. Figure 4As shown, the blocking cover assembly 150 can include a hinged seat 151 fixed on one side of the discharge port 140, a rotating shaft 152 rotatably arranged in the hinged seat 151, a blocking plate 153 arranged on the rotating shaft 152, and a stepping motor 154 for driving the rotating shaft 152 to rotate. The blocking plate 153 can be driven to rotate around the rotating shaft 152 by the stepping motor 154 to block the discharge port 140 during the rolling process, so as to avoid tea from falling out of the rolling groove 130, and the blocking of the discharge port 140 can be released after the rolling is completed, so as to facilitate the discharge of tea.

[0065] Further, as shown in Figure 5 , Figure 7 As shown, the surrounding plate assembly 120 includes a positioning ring 121, a rotating ring 122, and a plurality of arc-shaped rolling strips 123. The cross section of the positioning ring 121 is U-shaped, the rotating ring 122 is sealingly and rotatably arranged on the inner side of the positioning ring 121, so that the annular air duct 124 is formed between the positioning ring 121 and the rotating ring 122. The plurality of arc-shaped rolling strips 123 are uniformly fixed on the inner side of the rotating ring 122 in the circumferential direction. The outer side of the rotating ring 122 is provided with wind baffles 125 corresponding to the arc-shaped rolling strips 123 and adapted to the annular air duct 124. The rotating ring 122 is uniformly provided with air injection holes 126 between adjacent wind baffles 125. The surrounding plate assembly 120 further includes an air injection component. The air injection component has an air inlet pipe 127 tangent to the positioning ring 121 and in communication with the annular air duct 124. The air inlet direction of the air inlet pipe 127 is opposite to the rotating direction of the rolling cylinder 200. The surrounding plate assembly 120 further includes a limiting component for locking the rotating ring 122 when the rolling cylinder 200 rotates. The limiting component can lock the rotating ring 122 during the rolling process to avoid the rotation of the rotating ring 122, which affects the rolling effect of tea. At this time, the arc-shaped rolling strips 123 are equivalent to being fixed on the top of the rolling plate, and thus the tea in the rolling cylinder 200 can rub against the arc-shaped rolling strips 123 when the rolling cylinder 200 rotates, to complete the rolling work of tea. When the rolling is completed, the limiting component can unlock the rotating ring 122. At this time, the arc-shaped rolling strips 123 are equivalent to cleaning strips arranged on the top of the rolling plate. As shown in Figure 8 When the air injection component injects air into the annular air duct 124 through the air inlet pipe 127, the gas can rotate the rotating ring 122 by impacting on the wind baffles 125, and thus rotate the plurality of arc-shaped rolling strips 123 on the rolling plate around the central axis thereof, to clean the top of the rolling plate. On the other hand, the gas is discharged from the air injection holes 126 after entering the annular air duct 124. Since the gas discharged from the air injection holes 126 flows towards the center of the rolling plate, the airflow can move the tea scraped by the arc-shaped rolling strips 123 towards the center of the rolling plate, so as to be discharged from the discharge port 140, to realize the effect of automatically cleaning the residual tea.

[0066] It is worth mentioning that in the specific embodiment, the arc-shaped rubbing strip 123 is the same as the arc-shaped rubbing strip 123 on the rubbing disc 100 in the conventional technology, the air inlet direction of the air inlet pipe 127 is opposite to the rotating direction of the rubbing cylinder 200, and the arc-shaped rubbing strip 123 can push the tea leaves at the top of the rubbing plate to the center during rotation to make the tea leaves discharged from the discharge port 140.

[0067] In the specific embodiment, the positioning ring 121 is fixed relative to the rotating ring 122.

[0068] In order to improve the cleaning effect of the tea leaves remaining on the rubbing disc 100, in the specific embodiment, the gas introduced into the annular air channel by the air injection component through the air inlet pipe 127 is high-pressure gas. Specifically, the air pump connected to the air inlet pipe 127 can inject gas into the air inlet pipe 127, but considering that the impact force of high-pressure gas is large, the tea leaves can be blown out of the rubbing groove 130. Further, as shown in Figure 1 and Figure 8 The rubbing disc 110 has a stopping station 160, which corresponds to the air injection hole 126 and the annular air channel 124. After rubbing is completed, the rubbing cylinder 200 can be moved to the stopping station 160. Due to the arrangement of the air baffle 125, most of the gas introduced into the annular air channel by the air inlet pipe 127 is discharged from the air injection hole 126, that is, the air pressure of the gas discharged from the air injection hole 126 near the stopping station 160 is large. However, at this time, the rubbing cylinder 200 is in the stopping station 160, and the rubbing cylinder 200 can form an air baffle to prevent the tea leaves from being blown out of the rubbing groove 130.

[0069] Further, the air injection hole 126 is inclinedly arranged towards the inner arc surface of the arc-shaped rubbing strip 123.

[0070] As shown in Figure 7As shown in the specific embodiment, the air inlet pipe 127 penetrates the outer side of the positioning ring 121, the air inlet pipe 127 has an air inlet section 1271, a communication section 1272, and a blocking section 1273, the communication section 1272 has a coinciding area 12721 coinciding with the annular air duct 124 and a non-coinciding area 12722 located at one side of the annular air duct 124, the limiting component includes a locking block 128 slidingly arranged in the blocking section 1273, a connecting rod 129 slidingly arranged in the non-coinciding area 12722, and a blocking plate 1210 arranged in the air inlet section 1271, two ends of the connecting rod 129 are connected with the locking block 128 and the blocking plate 1210 respectively, the cross section of the blocking plate 1210 is smaller than the inner diameter of the air inlet section 1271, a reset spring 1211 is arranged between the end of the locking block 128 far away from the connecting rod 129 and one end of the blocking section 1273, and when the reset spring 1211 is in a normal state, the end of the locking block 128 close to the connecting rod 129 extends into the coinciding part.

[0071] As shown in the specific embodiment, Figure 7 As shown in the specific embodiment, during the rolling process, the first driving device drives the rolling cylinder 200 to rotate counterclockwise on the rolling disc 100, during the process, the tea in the rolling cylinder 200 rubs against the arc-shaped rolling strip 123 to generate an acting force on the rotating ring 122 to make the rotating ring 122 rotate counterclockwise, but during the process, the reset spring 1211 is in a normal state, the end of the locking block 128 close to the connecting rod 129 extends into the coinciding part, and the wind deflector 125 of the rotating ring 122 cannot rotate due to the blocking of the end of the locking block 128, that is, the rotating ring 122 is locked at this time, after the rolling is completed, the air injection component injects high-pressure gas into the air inlet pipe 127, the gas first flows in the air inlet section 1271 of the air inlet pipe 127 and impacts on the blocking plate 1210, the blocking plate 1210 moves towards the sliding part through the impact of the gas, the blocking plate 1210 and the locking block 128 are connected through the connecting rod 129, and then the locking block 128 also moves towards the blocking section 1273, so that the end of the locking block 128 moves out of the coinciding area 12721 of the sliding section, at this time, the wind deflector 125 can normally move in the annular air duct 124, and then the rotating ring 122 is automatically unlocked, the rotating ring 122 can automatically adapt to and meet different actual needs in the rolling process only by the air injection of the air injection component and the non-air injection.

[0072] In the specific embodiment, as shown in the specific embodiment, Figures 10-11As shown, the lifting assembly 500 comprises a telescopic guide component 510 and a driving component 520, the telescopic guide component 510 comprises a guide cylinder 511 fixedly fitted on one side of the rubbing cylinder 200 and a sliding column 512 slidably fitted in the guide cylinder 511, the sliding column 512 is fixedly connected with the sealing cover 400 through an L-shaped connecting piece 513, and the driving component 520 is used for driving the sliding column 512 to axially slide in the guide cylinder 511.
