[0047] The second structure can be that a plurality of warm air blowers 137 are installed on the tea leaf distribution conveyor 129, the first tea leaf conveyor 128, the second tea leaf conveyor 132 and the tea leaf supply conveyor 131.

[0048] The third structure can be that a plurality of warm air blowers 137 are installed on the tea leaf distribution conveyor 129 and the tea leaf supply conveyor 131.

[0049] The fourth structure can be that a plurality of warm air blowers 137 are installed on the first tea leaf conveyor 128, the second tea leaf conveyor 132 and the tea leaf supply conveyor 131.

[0050] It can be understood that the above four structures are not limited, and suitable installation structures can be selected according to needs.

[0051] The number of warm air blower installations can be 2, 3, 4, 5, 6, 7, 8, 9, or 10, etc. The warm air blower can provide hot air to the conveyor, which can heat the tea leaves conveyed by the conveyor, and can help slow down the temperature reduction of the tea leaves during the conveying process after the fixation.

[0052] It should be noted that the tea leaf distribution conveyor 129, the first tea leaf conveyor 128, the second tea leaf conveyor 132, and the tea leaf supply conveyor 131 are all mature web belt conveyors in the prior art.

[0053] It should also be noted that the warm air blower supplies hot air from the bottom of the web belt of the conveyor, and the hot air rises from the bottom to the top of the web belt, which can heat the web belt and the conveyed tea leaves.

[0054] As shown in Figure 1 , the first tea leaf conveyor 128 and the second tea leaf conveyor 132 can each convey tea leaves to two tea leaf guide cylinders 127, respectively. During conveying, the tea leaf conveyors can first convey tea leaves to one of the two tea leaf guide cylinders, and then reverse the direction to convey tea leaves to the other tea leaf guide cylinder. The tea leaf guide cylinders guide the tea leaves to the tea leaf guide bucket 136.

[0055] In some embodiments, a structure of the warm air blower mechanism is provided. The warm air blower mechanism is connected to the tea leaf guide bucket 136 and supplies hot air to the tea leaf guide bucket 136.

[0056] The tea leaf guide bucket is in communication with the rolling disc, and the hot air enters the rolling disc through the tea leaf guide bucket, which can provide heat to the tea leaves on the rolling disc.

[0057] As shown in Figure 1 , 2 , the warm air blower mechanism includes a warm air pipe 134, a warm air valve 134, and a warm air nozzle 135. The warm air pipe 134 is connected to one end of the warm air nozzle 135, the other end of the warm air nozzle 135 is installed in the tea leaf guide bucket, and the warm air valve 134 is installed in the warm air pipe 134 to control the supply or disconnection of hot air from the warm air pipe to the warm air nozzle.

[0058] Working mode:

[0059] The warm air valve 134 is opened, the warm air pipe 134 supplies hot air to the warm air nozzle 135, and the temperature of the hot air can be 45-55°C. While the warm air nozzle supplies hot air to the tea leaf guide bucket, the hot air can also assist in pushing the tea leaves in the tea leaf guide bucket into the rolling disc. The hot air enters the rolling disc through the tea leaf guide bucket, the rolling disc is heated, and the tea leaf hot rolling is realized.

[0060] The benefits of hot rolling and twisting of tea leaves include: 1. Promote cell rupture: hot rolling and twisting breaks the cell wall of tea leaves through heating and mechanical force, releasing cell sap, which helps to evenly distribute the contents of tea leaves and enhance the concentration and taste of tea soup. 2. Accelerate fermentation: for fermented tea (such as black tea, oolong tea), hot rolling and twisting can accelerate the reaction of enzymes and polyphenols, promote fermentation, and form unique aroma and color. 3. Improve the appearance of tea leaves: hot rolling and twisting makes tea leaves soft and easy to shape, forming tea leaves with tight and beautiful appearance, improving the value of goods. 4. Enhance aroma: during the process of hot rolling and twisting, the aroma of tea leaves is volatilized by heat, which helps to form aroma and make tea leaves more fragrant. 5. Improve drying efficiency: hot rolling and twisting reduces the moisture content of tea leaves, reduces the subsequent drying time, improves production efficiency, and helps to maintain the quality of tea leaves. 6. Improve taste: hot rolling and twisting makes the contents of tea leaves more easily dissolved, the tea soup is more mellow, the astringency is reduced, and the taste is better.

[0061] In some embodiments, a structure of the unloading and deblocking mechanism is given. As shown in Figure 5 The unloading and deblocking mechanism includes a leaf uniformizing and deblocking cylinder 1441, a leaf uniformizing and deblocking shaft 1444, a deblocking drive motor 1438, and a cover mechanism. The leaf uniformizing and deblocking cylinder 1441 is vertically installed at the bottom of the unloading port 121; the leaf uniformizing and deblocking shaft 1444 is placed in the leaf uniformizing and deblocking cylinder 1441, both ends are rotationally connected with the leaf uniformizing and deblocking cylinder 1441, and a plurality of deblocking rods 1445 are distributed on the circumferential side of the shaft in the axial direction; the deblocking drive motor 1438 is installed on the leaf uniformizing and deblocking cylinder 1441 and is in transmission connection with the leaf uniformizing and deblocking shaft 1444; the cover mechanism is movably placed between the unloading port 121 and the leaf uniformizing and deblocking cylinder 1441, and the unloading port is opened and closed.

[0062] The number of deblocking rod installations can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, or 22, etc.

[0063] One installation structure of the deblocking drive motor 1438, a second motor table 1439 is installed, the second motor table 1439 is installed on the leaf uniformizing and deblocking cylinder 1441, and is used to support the installation of the deblocking drive motor 1438.

[0064] The rotation connection of the leaf uniformizing and deblocking shaft with the leaf uniformizing and deblocking cylinder 1441 is that the leaf uniformizing and deblocking shaft 1444 is connected with the leaf uniformizing and deblocking cylinder 1441 through a bearing seat 1443. That is, the two ends of the leaf uniformizing and deblocking shaft 1444 are respectively installed on the leaf uniformizing and deblocking cylinder 1441 through a bearing seat 1443.

[0065] Working mode:

[0066] The cover mechanism is in an open state for the discharge port 121, and the tea balls on the rubbing and twisting disc fall into the uniformity and deagglomeration cylinder 1441 through the discharge port. The deagglomeration driving motor 1438 is in transmission connection with the uniformity and deagglomeration shaft 1444 through the first driving shaft 1442. The deagglomeration driving motor 1438 drives the first driving shaft 1442 to rotate, and the first driving shaft 1442 drives the uniformity and deagglomeration shaft 1444 to rotate. The uniformity and deagglomeration shaft 1444 drives the plurality of deagglomeration rods 1445 thereon to rotate, and the plurality of deagglomeration rods 1445 rotate and hit the falling tea balls, so that the tea balls are deagglomerated and loosened, and the deagglomeration and loosening effect is realized.

[0067] In some embodiments, a structure of the cover mechanism is shown as follows. Figure 5 The cover mechanism includes a first limiting seat 1431, a second limiting seat 1435, a cover plate 1434, and a cover plate driving motor 1447. The cover plate driving motor 1447 is provided with a second driving shaft 1448. The first limiting seat 1431 is provided with a first limiting sensor 1432. The second limiting seat 1435 is provided with a second limiting sensor 1436 and is arranged in a spaced manner with the first limiting seat 1431. One end of the cover plate 1434 is provided with a touch rod 1433, and the other end is provided with a swing rod 1437. The cover plate driving motor 1447 is in transmission connection with the swing rod 1437 through the second driving shaft 1448. The cover plate driving motor 1447 drives the swing rod 1437 to swing, and the cover plate 1434 drives the touch rod 1433 to swing between the first limiting seat 1431 and the second limiting seat 1435.

[0068] The first limiting seat 1431 and the second limiting seat 1435 can be U-shaped seats. The first limiting seat and the second limiting seat can support the touch rod.

[0069] The second driving shaft 1448 and the swing rod 1437 can be connected through a key.

[0070] It should be noted that when the touch rod 1433 is on the first limiting seat 1431, the cover plate 1434 closes the discharge port 121 at this time. When the touch rod 1433 is on the second limiting seat 1435, the cover plate 1434 is separated from the discharge port 121, and the discharge port 121 is in an open state. The tea balls on the rubbing and twisting disc can be discharged through the discharge port.

[0071] The first limiting sensor 1432 and the second limiting sensor 1436 are electrically connected with the cover plate driving motor 1447, and are used to limit the work of the deagglomeration driving motor.

[0072] It can be understood that in order to facilitate the control of the work of the deagglomeration driving motor and the cover plate driving motor, a control module (not shown in the figure) is added. The first limiting sensor 1432, the second limiting sensor 1436, the cover plate driving motor 1447, and the deagglomeration driving motor 1438 are electrically connected with the control module.

[0073] It should be noted that the action control of the control module and the devices connected thereto used in the present application belongs to mature single-chip technology and can be easily purchased from the market and used after simple debugging.

[0074] Working mode:

[0075] In the initial state, the touch rod is placed in the first limiting seat 1431. The control module controls the work of the sealing plate driving motor 1447 and the block dismounting driving motor 1438, the sealing plate driving motor 1447 drives the second driving shaft 1448 to rotate, the second driving shaft 1448 drives the swing rod 1437 to rotate, the swing rod 1437 drives the sealing plate 1434 to swing, the sealing plate 1434 drives the touch rod 1433 to rotate to the second limiting seat 1435, and the touch rod 1433 touches the second limiting sensor 1436. The second limiting sensor 1436 sends a data signal to the control module, and the control module receives the data signal to control the sealing plate driving motor 1447 to pause work.

[0076] The control module can be set to control the block dismounting driving motor 1438 to pause work 30-60 seconds after the touch rod 1433 touches the second limiting sensor 1436. The sealing plate driving motor 1447 drives the second driving shaft 1448 to rotate, the second driving shaft 1448 drives the swing rod 1437 to rotate, the swing rod 1437 drives the sealing plate 1434 to swing, the sealing plate 1434 drives the touch rod 1433 to rotate to the first limiting seat 1431, and the touch rod 1433 touches the first limiting sensor 1432. The first limiting sensor 1432 sends a data signal to the control module, and the control module receives the data signal to control the sealing plate driving motor 1447 and the block dismounting driving motor 1438 to pause work, and the sealing plate 1434 is closed to the discharge port.

[0077] It should be noted that the control module can also be set to T after the touch rod touches the first limiting sensor, and the value of T can be 20-60 min. After the touch rod touches the first limiting sensor for 20, 30, 40, 50 or 60 min, the control module controls the sealing plate driving motor 1447 and the block dismounting driving motor 1438 to work again, which is repeated in combination with the above.

[0078] In some embodiments, in order to further uniform the leaves and dismount the blocks, a uniform leaf dismounting machine 16 is installed, which is installed on the twisted tea conveying machine 15 and used for uniforming the leaves and dismounting the blocks of the tea conveyed by the twisted tea conveying machine 15.

[0080] The number of the uniformity leaf unblocker rods 165 can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21 or 22, etc.

[0081] Working mode:

[0082] The uniformity leaf unblocker motor 162 drives the speed reducer 163 to work, the speed reducer 163 drives the uniformity leaf rotating shaft 164 to work, and the uniformity leaf rotating shaft 164 drives the plurality of uniformity leaf unblocker rods thereon to rotate, the plurality of uniformity leaf unblocker rods perform uniformity leaf unblocking on the tea leaves conveyed by the rolled tea leaf conveyor, and the tea leaves are uniformly unblocked again, so that the tea leaf balls or blocks are effectively prevented from entering the next tea processing procedure.

[0083] In some embodiments, a structure of the swing mechanism is given. The swing mechanism includes a first swing arm 111 and a second swing arm 115. One end of the first swing arm 111 is connected with a rolling movable plate 117; one end of the second swing arm 115 is rotationally connected with the other end of the first swing arm 111 through a first support shaft 112, and the other end is rotationally connected with the rolling workbench 11 through a second support shaft 116.

[0084] A connection structure of the first swing arm and the second swing arm: one end of the first swing arm is provided with a first shaft sleeve 113. Both ends of the second swing arm are provided with second shaft sleeves 114. The first shaft sleeve 113 on the first swing arm is connected with a second shaft sleeve on one end of the second swing arm 115 through the first support shaft 112. The first swing arm and the second swing arm can rotate relative to each other.

[0085] It should be noted that when the swing mechanism is in transmission connection with the rolling drive motor 110, the rolling drive motor 110 is in transmission connection with the second support shaft 116. The second support shaft is fixedly connected with the second swing arm. When the rolling drive motor drives the second support shaft 116 to rotate, the second support shaft 116 drives the second swing arm to rotate, the second swing arm pushes the first swing arm to swing, and the first swing arm drives the rolling movable plate 117 to swing.

[0086] In some alternative embodiments, a structure of a tea leaf pushing machine is provided. The tea leaf pushing machine is used to push the tea leaves in the tea leaf guiding and protecting barrel into the rolling disc. The tea leaf pushing machine comprises a tea leaf pushing plate 141 and a third swing arm 139. One end of the tea leaf pushing plate 141 is rotationally connected to the rolling workbench 11 through a fourth supporting shaft 142; one end of the third swing arm 139 is connected to the rolling movable plate 117, and the other end is rotationally connected to the tea leaf pushing plate 141 through a third supporting shaft 140.

[0087] The third swing arm 139 is provided with a third shaft sleeve 138, and the third shaft sleeve 138 is connected to the tea leaf pushing plate 141 through the third supporting shaft 140. That is, one end of the third supporting shaft 140 is rotationally connected to the third shaft sleeve 138, and the other end is connected to the tea leaf pushing plate 141.

[0088] When the rolling movable plate 117 swings, the third swing arm 139 swings, and the third swing arm 139 drives the tea leaf pushing plate 141 to swing through the third supporting shaft 140. When the tea leaf pushing plate 141 swings, the tea leaves in the tea leaf guiding and protecting barrel 136 are pushed into the rolling disc 12.

[0089] It can be understood that the tea leaf pushing plate can rotate relative to the rolling workbench through the fourth supporting shaft. The third swing arm can rotate relative to the third supporting shaft through the third shaft sleeve.

[0090] In some alternative embodiments, a structure of a rolling and pressing mechanism is provided. The rolling and pressing mechanism comprises a rolling cylinder 119, a rolling and pressing cover 120, a screw lifting machine 122, and a temperature sensor 144. The rolling cylinder 119 extends to the rolling disc 12 through the rolling movable plate 117; the rolling and pressing cover 120 is movably arranged in the rolling cylinder 119, the top of which is connected to a sliding support 125, the sliding support 125 is slidingly installed on a supporting frame 124, and the supporting frame 124 is installed on the rolling movable plate 117; the screw lifting machine 122 is provided with a telescopic screw rod, which is installed on the supporting frame 124, and the screw rod is connected to the sliding support 125 through a supporting rod 123; and the temperature sensor 144 is installed on the sliding support 125.

[0091] It can be understood that a controller (not shown in the figure) is added to facilitate the operation of the rolling and pressing mechanism. The controller is electrically connected to the rolling and pressing mechanism.

[0092] In order to further strengthen the connection between the rolling cylinder and the rolling movable plate, a reinforcing sleeve 118 is added. The rolling cylinder is installed on the rolling movable plate 117 through the reinforcing sleeve 118.

[0093] It should be noted that a cylinder hole for installing the rolling cylinder is formed on the rolling movable plate.

[0094] When the screw lifting machine works, the screw rod can be driven to extend or retract. The length of the screw rod can be adjusted according to the rolling needs. The screw rod drives the rolling and pressing cover to move towards the rolling disc, so as to increase the rolling pressure.

[0095] The structure of the screw lifting machine comprises a screw lifting machine 1221, a lifting drive motor 1222 and an encoder 1223. The screw lifting machine 1221 is provided with a screw rod and an input shaft, both ends of the input shaft extending out of the screw lifting machine, one end of the input shaft being in transmission connection with the lifting drive motor 1222, and the other end being connected with the encoder 1223. The screw lifting machine 1221 is installed on the support frame 124.

[0096] The lifting drive motor 1222 drives the input shaft to rotate, the input shaft drives the screw lifting machine 1221 to work, and the screw lifting machine 1221 drives the screw rod to move.

[0097] The lifting drive motor 1222 and the encoder 1223 are both electrically connected with the controller. The encoder transmits data information to the controller in real time, the controller controls the lifting drive motor to work according to the data information transmitted by the encoder, and then controls the screw lifting machine to work, so as to realize the regulation and control of the movement of the screw rod.

[0098] It should be noted that when the lifting machine drive motor drives the input shaft to rotate clockwise, the screw lifting machine drives the screw rod to stretch out. When the lifting machine drive motor drives the input shaft to rotate counterclockwise, the screw lifting machine drives the screw rod to contract.

[0099] The stretching of the screw rod can increase the rolling pressure of the rolling cover. The contraction of the screw rod can reduce the rolling pressure of the rolling cover.

[0100] It can be understood that the structure of the screw lifting machine can be a mature screw lifting machine in the prior art.

[0101] The temperature sensor 144 is installed on the sliding support 125 through the sensor support 145. The temperature sensor can monitor the air temperature of the rolling disc in real time during rolling.

[0102] The upper limit value and the lower limit value can be set on the encoder. The lower limit value can correspond to the maximum height of the contraction of the screw rod, and the upper limit value can correspond to the maximum length of the stretching of the screw rod. It can be understood that when the screw rod is at the maximum stretching length, the interval between the rolling cover and the rolling disc is the smallest. When the encoder is at the upper limit value, the controller can control the lifting machine drive motor to stop working, and the stop time can be the time required for tea rolling. After the rolling time is reached, the controller controls the lifting machine drive motor to work in reverse, and the screw rod contracts upward to the height corresponding to the lower limit value of the encoder.

[0103] Obviously, the above embodiments are only examples for clearly illustrating the present application and are not intended to limit the present application. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
