DETAILED DESCRIPTION

[0021] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0022] As the instruction manual Figure 1-8 As shown, a Lu'an melon slice fixing, rolling and stripping machine includes a feeder 1, a bionic arm structure 2, a reduction motor 3, a frame 4, a heating and insulation structure 5, a wok structure 6, and an automatic control system 7. The feeder 1 includes a feeder frame 14 for support, a feeder outlet 11 arranged at an oblique upper portion, a conveyor belt 12 and a collecting trough 13 for conveying materials, and a wok structure 6 is arranged below the feeder outlet 11, and the wok structure 6 is installed on the frame 4.

[0023] The wok of the wok structure 6 is a traditional iron wok for frying Lu'an melon slices. Its shape is approximately a semi-spherical cast iron wok, but its opening is wide, with a diameter of 850mm. A circular enclosure structure is added above it, which is close to the palm-beating brush. The discharge port is located in the middle of the enclosure structure, and the discharge port is controlled to be opened and closed by toggling the slide. The enclosure structure is connected to the iron wok with a buckle, and a handle is designed on it for easy disassembly, maintenance and installation.

[0024] The reduction motor 3 is installed at the lower position on one side of the frame 4 and provides power to the bionic arm structure 2 through a chain. The bionic arm structure 2 includes a bionic arm drive shaft 24 and multiple bionic arms, which are, from left to right, a left bionic arm 21, a middle bionic arm 22, and a right bionic arm 23. The bionic arm structure 2 is installed above the wok structure 6 and its bionic arm drive shaft 24 is distributed on the transverse geometric diameter of the wok structure 6.

[0025] Multiple bionic arms all include a bionic arm adjustment rod 211 for connecting the bionic arm drive shaft 24, a clamping plate 212 and a tapping and pressing brush 213. The tapping and pressing brush 213 is fixedly mounted on the bionic arm adjustment rod 211, and the clamping plate 212 is fixedly mounted on the inner surface of the tapping and pressing brush 213. The middle side bionic arm 22 is symmetrical along the perpendicular midline, and includes two symmetrically arranged and fixedly combined tapping and pressing brushes 213. A clamping plate 212 is symmetrically mounted on each of the two tapping and pressing brushes 213, and the inner edges of the two clamping plates 212 are in contact with each other.

[0026] The right bionic arm 23 is chirally symmetrical to the left bionic arm 21 .

[0027] Driven by the reduction motor 3, the bionic arm structure 2 rotates, and the three bionic arms perform eight actions in the wok: pushing, turning, flipping, throwing, patting, pressing, arranging and sweeping. The motor model used by a single machine is 51K120RGU-CF, with a power of 120w. When multiple machines are combined, they are equipped with motors of appropriate power.

[0028] The heating and heat-insulating structure 5 includes a heating layer and a heat-insulating layer. The heating layer is fixed on the top of the heat-insulating layer. The heating layer is a flexible heating rope-type heater woven into a group with a width of 4 cm. The number of groups can be freely added according to the actual size and shape of the pot. The frying temperature required for Lu'an melon slices is concentrated in the upper part of the pot, so a woven heating sheet shaped like two-thirds of a semicircular sphere is needed to provide a heat source for the wok, and the power is adjusted by controlling whether each group of heating sheets is working or not. The temperature of each area can be arbitrarily changed by changing the weaving density. The heat-insulating layer structure uses strip-shaped heat-insulating cotton, which is spliced ​​into the same shape as the bottom of the pot, and each group of woven heating layers is directly fixed on the heat-insulating cotton.

[0029] The automatic control system 7 includes a display control panel and a host computer control unit. The host computer control unit is electrically connected to the controller, circuit breaker, motor controller and data acquisition card. The automatic control system 7 controls the start, stop, forward and reverse rotation and stepless adjustment of the rotation speed of the bionic arm. It can quickly and accurately adjust the speed according to the different stir-frying speeds required in the processing process. The tea leaves are fried when it rotates forward and the tea leaves are discharged when it rotates reversely.

[0030] The controller is electrically connected with a heater, the heater is in contact with the heating layer, the heater is in contact with the temperature sensor, the temperature sensor transmits the collected temperature data to the data acquisition card and then feeds back to the host computer control unit, the automatic control system 7 can adjust the temperature to any temperature within 0-400 degrees Celsius, with an accuracy of ±2 degrees Celsius, the multi-point sensor feeds back to the temperature control system by real-time detection of the temperature of the heating plate, according to the set adjustment interval, if the temperature exceeds the temperature control interval, the temperature control system will control the operation and disconnection of the heating plate to achieve temperature control, so this machine can be applied to the processing and production needs of different types of tea. The automatic control system 7 realizes monitoring, alarm and control, the temperature sensor can perform temperature monitoring, the system also includes image display and alarm functions, the image display allows the operator to view the status of the tea in real time, the alarm function prompts the operator to process the operation, the control program receives various signals for integration and sends control signals to control the corresponding actuator, the automatic control system 7 can realize the stepless speed regulation, forward and reverse rotation, start and stop of the reduction motor 3, the stepless speed regulation can make this machine suitable for the frying of different types of tea, the forward and reverse rotation can easily realize the frying operation and discharging, and the stop switch can realize emergency braking in unexpected situations.

[0031] In the present invention, the feeder 1 is integrated with the collection, feeding and automatic control, and is controlled by the automatic control system 7 to automatically feed the tea frying machine, and the conveyor belt speed can be adjusted according to the actual needs of the user to change the feeding amount.

[0032] The whole machine of the new type can be assembled into multiple units to work synchronously, and each machine is synchronously connected to each other through a coupling. When the machines are connected and work synchronously, only the motor of each machine needs to be replaced.

[0033] The bionic arm structure is based on the operation actions of tea masters with many years of experience in frying Lu'an Guapian. The eight specific actions are summarized as follows: push, turn, flip, throw, pat, press, sort and sweep. The three frying arms fit these eight actions. They are located on the left, right and middle of the wok through shaft transmission. The pat and press brush is a palm brush made of the silky wrapping of the palm tree trunk. It is collected and shaped and pressed to form a tea pat and press brush. The shape of the middle pat and press brush is two symmetrical and arrow-shaped pieces. There is a gap between the front and the bottom of the pot, and it fits more and more to the bottom of the pot backwards. The pat and press brushes on both sides are one side of the middle. The bionic arm and the palm brush cooperate with each other to contact the tea leaves at the bottom of the pot to push the tea leaves. Then the tea leaves are squeezed by the palm brush and the bottom of the pot to rotate upward, and the tea leaves are turned upward again. At the same time, the palm brush pats, presses and sorts the tea leaves in these three intervals. After that, the tea leaves are brought to the highest point and thrown into the air. This is repeated until the tea leaves are fried and the motor reverses to sweep out the tea leaves.

[0034] When the operation starts, the host computer starts the motor to drive the rotating shaft to rotate the bionic arm, and at the same time sets the temperature of the heating belt to start heating the wok. When the temperature reaches the specified temperature, the indicator light of the wok lights up, and feeding can be carried out at this time. The feeder starts working, and the indicator light of the feeder lights up. When the material is delivered, the system controls the feeder to stop working. The tea leaves start to be fried, and the bionic arm cycles the first seven actions. When the tea leaves are fried, the completion indicator lights up to remind the user to prepare for discharge. At this time, the system controls the discharge port to open, and the motor reverses to sweep out the fried tea leaves.

[0035] During operation, tea leaves enter the wok, and the bionic arm simulates manual tea frying by pushing, turning, flipping, throwing, patting, pressing, sorting and sweeping in the wok. The material is evenly heated and shaped under the action of the bionic arm. Figure 7 As shown in the figure, the bionic arm mechanism and the palm layer cooperate with each other to contact the tea leaves at the bottom of the pot to push the tea leaves, and then move upwards to form a rotation due to the squeeze of the palm brush and the bottom of the pot, and then the tea leaves flip upwards again. At the same time, in these three intervals, the palm brush pats, presses and sorts the tea leaves, and then the tea leaves are brought to the highest point and thrown into the air, and this is repeated until the tea leaves are fried. The motor reverses and sweeps out the tea leaves. At the same time, the control system monitors each step of the process in real time, accurately controls the motor speed, wok temperature and frying time, and its alarm function can remind users to handle materials in time to ensure the quality and efficiency of the materials.
