Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and more specifically relates to an Enshi Yu Lu intelligent shaping machine and a digital shaping method. Background Art

[0002] As a traditional steamed green tea in my country, the processing technology of Enshi Yulu is divided into steaming, fanning, frying with first-grade fire, rolling, frying with second-grade fire, shaping and polishing, baking, and picking. Among them, shaping and polishing is one of the processing procedures of Enshi Yulu tea. It is an important process for Enshi Yulu tea to be shaped like a needle. The tea leaves are kept soft by rolling them to prevent them from breaking until the moisture content is about 25%. Then, the tea leaves are tightened and polished. The tea leaves lose water continuously during the forming process until the tea leaves are broken by hand and taken off the machine.

[0003] At present, the traditional shaping and polishing methods of Enshi Yu Lu tea are divided into two stages: rubbing and tightening. When rubbing, tea farmers hold an appropriate amount of tea leaves in both hands, with palms facing each other, four fingers bent, and rubbing in the same direction; when tightening, four techniques of arranging, rubbing, holding and tying can be used. On the roasting plate, hands do not leave the tea, and the tea does not leave the roasting oven until the tea is formed. The traditional shaping method requires a lot of manpower and material resources and is not suitable for mass production.

[0004] At present, most of the shaping machines on the market use fine kneading machines. Tea leaves are kneaded and refluxed back and forth on the fine kneading machines, and the tea leaves are heated and shaped at the same time. Tightening and polishing are generally processed by strip sorting machines, and the strips are polished by reciprocating motion of the trough pot. However, single-machine operation has problems such as low automation and high labor costs. Although the current shaping and polishing production line can improve production efficiency during processing, they are assembled by fine kneading machines and strip sorting machines, and a conveying device is connected in the middle. However, the tea conveying device cannot be insulated and cannot meet the requirements of continuous heating during shaping and polishing operations. In addition, the current fine kneading machine uses a heavy block lever for pressurization. The force on the tea leaves cannot be accurately controlled during the pressurization process. It is difficult to recover the heavy excess materials during the fine kneading loading and unloading process, and the tea leaves are prone to accumulation during the feeding and discharging process, which still requires manual control.

[0005] In addition, the judgment of the degree of shaping and polishing in production mainly relies on manual experience, which is subjective to a certain extent. The moisture content is an important indicator for evaluating the completion of the shaping and polishing operation. Studies have shown that the moisture content needs to be around 15% at the end of the shaping process, and the moisture content needs to be around 8-9% at the end of the polishing process. At this time, the quality of processed tea is relatively high. With the aggravation of population aging and the continuous reduction of rural labor force, the problem of population resources has become prominent. In view of the problems of high labor intensity and low strip formation rate of traditional shaping and polishing processes in the current market, it is urgent to develop an intelligent shaping machine and digital shaping method for Enshi Yulu to solve the problem of Enshi Yulu processing in my country and improve the economic benefits of my country's tea.

[0018] Correspondingly, the present invention also provides a method for digitally shaping Enshi Jade Dew, the steps of which are:

[0019] Step A, the shaping machine and the polishing machine are started to work through the control system, and the temperatures of the shaping machine and the polishing machine are set to 100-120°C and 40-50°C respectively. The real-time temperature is collected by the temperature sensor and compared with the set temperature. When the real-time temperature reaches the set temperature, the automatic feeding system starts feeding;

[0020] Step B, steam-killing, cooling and rehydrating, rolling and deblocking, stripping or drying the Longjing 43 one-bud two-leaf tea leaves selected as raw materials until the tea moisture content is 20-25%, and then cooling and rehydrating the tea leaves and putting them on the chain plate elevator to start feeding, the control system controls the chain plate elevator to feed, when the infrared light-emitting tube of the photoelectric switch arranged at the feeding end of the tea belt conveyor is blocked by the tea leaves, the control system receives a signal that there are tea leaves on the tea belt conveyor, and at this time the control system controls the tea belt conveyor and the tea spreading machine to start working, and the tea leaves move left and right, and the outlet of the weighing machine moves to the top of the first conical feeding mechanism in the first row;

[0021] Step C, when the tea leaves in the tea belt conveyor fall into the tea spreading machine, the control system controls the tea spreading machine to rotate forward first, and the tea leaves fall into the tea moving left and right weighing machine. When the tea moving left and right weighing machine senses the weight of the tea leaves, the control system receives a signal that there are tea leaves on the tea moving left and right weighing machine. At this time, the control system controls the front row tea moving left and right weighing machine to start working, and the tea leaves enter the conical feeding mechanism, the cylinder is turned on, and the tea leaves fall into the weighing platform. When the control system receives that the tea leaves on the weighing platform reach the set weight, the cylinder is closed, and the tea leaves enter the shaping machine to start shaping; at the same time, the control system controls the tea spreading machine to reverse, and the rear row tea moving left and right weighing machine moves to The tea leaves are unloaded from the top of the first conical feeding mechanism in the second row, and the unloading action is repeated; when the unloading of the last shaping machine is finished and the work of the first shaping machine has not been finished, the control system controls the tea leaves to move the weighing machine left and right to convey the tea leaves to the belt elevator, and then the tea leaves fall into the chain plate elevator after passing through the residual material recovery conveyor, so as to realize residual material recovery, until the tea leaves in the first shaping machine in the first row meet the requirements of the control system, and the shaping is completed, and the tea leaves enter the feeding port of the polishing machine from the tea outlet door of the shaping machine. When the tea outlet door of the shaping machine is closed, the control system receives the closing signal, and the weighing machine of the front row of tea leaves moves left and right and starts to move to the top of the conical feeding mechanism again, and the above operation is repeated;

[0022] Step D, the tea leaves start to be shaped, and the control system automatically calculates the optimal working parameters based on the standardized data in the database and starts to record the shaping data; when working, the control system receives the data information obtained by the pressure, position sensor, pressure sensor, first temperature sensor, and humidity sensor in real time for analysis, controls the working parameters of the shaping device in the current production and processing process, and uploads them to the control system at the same time; the control system collects the current pressure, position, temperature, and humidity in real time, and will continue to run if the exit condition is not triggered; when the temperature exceeds the specified temperature, the heating tube is turned off; when the humidity exceeds the set humidity requirement, the dehumidifier is turned on; when the tea leaves in the shaping machine reach the specified weight, it starts to shape according to the optimal working parameters, and when the shaping time is reached, the shaping degree is judged by the method of multi-morphological feature machine vision to judge whether the tea leaves meet the unloading requirements, and unloading starts if they meet the requirements; If the tea leaves do not meet the requirements for unloading, the processing will continue until the method of multi-morphological feature machine vision determines that the shaping degree meets the requirements, and then the tea leaves will start to be unloaded; when the tea leaves start to be unloaded, the corresponding shaping machine starts to work, the motor drives the swing shaft to start swinging, and the rubbing hand installed on the swing shaft swings back and forth on the rubbing plate. The tea leaves continue to move in the same direction under the action of the rubbing hand, and the pressure cover applies pressure to the tea leaves as the connecting piece swings. The excess tea leaves are scattered to both sides of the rubbing plate. Under the action of the swing plate and the rotating plate, the tea leaves move to the rubbing plate again. After repeated rubbing, the tea leaves are gradually formed into strips; after the loading is completed, the shaping starts, and the original images of the shaped tea leaves on both sides of the rubbing plate are collected; the original images are read, and a ResNet-20 convolutional neural network model is constructed. The original images are used as input to determine whether the strip forming rate requirements are met. If the conditions are met, unloading starts;

[0023] Step E, after the shaping is completed, the tea leaves enter the feed port of the polishing machine from the tea outlet door of the shaping machine. The control system receives that the tea outlet door of the shaping machine is opened, and at this time the control system starts the cylinder of the polishing machine to start forward rotation; at this time, the shaped tea leaves fall into the cylinder from the feed port of the polishing machine for polishing operation. The polishing temperature is 40-50 degrees, the speed is 20-25r / min, and the time is 20-30min. The weight sensor installed under the cylinder by the roller bracket determines the degree of water loss of the tea leaves in the cylinder. When the control system receives that the weight of the tea leaves in the cylinder reaches the set weight, the cylinder is controlled to reverse, and the tea leaves are polished. The leaves enter the mobile discharging system through the discharging port on the cylinder; during the shaping process, the second temperature sensor monitors the temperature of the cylinder in real time. When the temperature exceeds the set temperature of the control system, the heating is stopped; the temperature collected by the second temperature sensor is compared with the set temperature, and the moisture content data calculated by the weight data collected by the weight sensor installed on the cylinder is compared with the moisture content set by the control system; when the control system receives the signal of cylinder reversal, the motor III, motor IV and fan II on the mobile discharging system are controlled to start running, and the tea leaves fall onto the stainless steel mesh belt for cooling and are transported to the next process.

[0025] 1.

Compared with the traditional method, users do not need to frequently carry excess tea leaves manually, which reduces workload and improves work efficiency.

[0026] 2. The weight block of the shaping machine in the present invention is moved by a slide rail, which can effectively control the pressurization pressure, realize the digitization of the pressure in the shaping process, and effectively improve the efficiency and standard of shaping.

[0027] 3. The present invention uses a suction fan to absorb the table material through the fan duct, so as to realize automatic cleaning of the table of the shaping machine after the shaping is completed.

[0028] 4. In the present invention, the tea leaves after shaping directly enter the polishing machine. The tea leaves are heated all the time during the shaping and polishing process, realizing the process of keeping hands on the tea leaves and tea leaves in the roasting furnace in the traditional shaping process, effectively improving production efficiency and reducing labor intensity.

[0029] 5. The particle swarm algorithm optimized long short-term memory neural network model of the present invention takes tea variety, tea grade, leaf weight, and moisture content of tea before shaping as inputs, and takes shaping temperature, polishing temperature, shaping time, polishing time, pressurizing time, applied pressure, polishing speed, strip forming rate, and tea breaking rate as outputs, constructs a particle swarm algorithm optimized long short-term memory neural network model with 4 inputs and 9 outputs, and timely feedbacks and adjusts parameters, which is simple to operate and takes less time, and can more accurately predict the shaping process.

[0030] 6. The control system of the present invention is used to judge the degree of shaping and polishing of tea leaves, as well as the moisture content of the tea leaves shaping process. It can not only realize the digital operation of the shaping and polishing process of Enshi Yulu, but also the automatic feeding system can recycle the excess tea leaves that have not entered the shaping machine. Compared with the traditional method, the present invention does not require users to frequently carry excess tea leaves manually, which reduces the workload and improves work efficiency.

[0063] The shaped tea leaves enter the feed port 8-18 of the polishing machine 8 from the discharge port of the shaping machine 6, and enter the drum through the feed port 8-18. At this moment, the drum rotates forward, and the shaped tea leaves enter the cylinder 8-20 through the feed port 8-18 for polishing.

The cylinder 8-20 is reversed, and the tea leaves fall from the discharge port 8-16 of the cylinder to complete the polishing operation. Through the four weight sensors 8-7 installed below the cylinder 8-20, the quality signal of the tea leaves in the cylinder is received to control the forward and reverse rotation of the motor, so as to ensure that the tea leaves inside the cylinder 8-20 are discharged at a reasonable moisture content, thereby improving the polishing effect of the Enshi Yu Lu tea leaves. The Enshi Yu Lu made after the friction and polishing of the cylinder has a high striping rate, which can make the color of the Enshi Yu Lu greener and improve the forming effect.

[0066] Embodiment 2:

[0067] The digital shaping method of the Enshi Yulu intelligent shaping machine based on Example 1 includes the steps of continuous dynamic cycle feeding, shaping, polishing, moving discharging and the like, and specifically includes the following steps:

[0068] Step A, the shaping machine 6 and the polishing machine 8 start working through the control system, and the temperatures of the shaping machine 6 and the polishing machine 8 are set to 100-120°C and 40-50°C respectively. The real-time temperature is collected by the temperature sensor and compared with the set temperature. When the real-time temperature reaches the set temperature, the automatic feeding system starts feeding;

[0069] Step B, steam-killing, cooling and rehydrating, rolling and deblocking, stripping or drying the Longjing 43 one-bud two-leaf tea leaves selected as raw materials until the tea moisture content is 20-25%, and then cooling and rehydrating, putting the tea leaves on the chain plate elevator 1 to start feeding, and the control system controls the chain plate elevator 1 to feed, when the infrared light-emitting tube of the photoelectric switch set at the feeding end of the tea belt conveyor 2-1 is blocked by the tea leaves, the control system receives a signal that there are tea leaves on the tea belt conveyor 2-1, and at this time the control system controls the tea belt conveyor 2-1 and the tea distributor 3 to start working, and the tea leaves move left and right, and the outlet of the weighing machine moves to the top of the first (from left to right) conical feeding mechanism 6-29 in the first row;

[0070] Step C, when the tea leaves in the tea belt conveyor 2-1 fall into the tea spreading machine 3, the control system controls the tea spreading machine 3 to rotate forward first, and the tea leaves fall into the tea moving left and right weighing machine. When the tea moving left and right weighing machine senses the weight of the tea leaves, the control system receives a signal that there are tea leaves on the tea moving left and right weighing machine. At this time, the control system controls the front row tea moving left and right weighing machine 4-1 to start working, and the tea leaves enter the conical feeding mechanism 6-29, the cylinder 6-30 is turned on, and the tea leaves fall into the weighing platform 6-31. When the control system receives that the tea leaves on the weighing platform 6-31 reach the set weight, the cylinder 6-30 is closed, and the tea leaves enter the shaping machine to start shaping; at the same time, the control system controls the tea spreading machine 3 to reverse, and the rear row tea moving left and right weighing machine 4-2 moves to the first The tea leaves are unloaded from the top of the first (from left to right) conical feeding mechanism 6-29 in the second row, and the unloading action is repeated; when the unloading of the last shaping machine is completed and the work of the first shaping machine has not yet been completed, the control system controls the weighing machine to move the tea leaves left and right to transport the tea leaves to the belt elevator 5, and the tea leaves fall into the chain plate elevator 1 after passing through the residual material recovery conveyor 2-2, so as to realize residual material recovery, until the tea leaves in the first shaping machine in the first row meet the requirements of the control system, and the shaping is completed, and the tea leaves enter the feeding port 8-18 of the polishing machine 8 through the tea outlet door 6-33 of the shaping machine. When the tea outlet door 6-33 of the shaping machine is closed, the control system receives the closing signal, and the weighing machine 4-1 in the front row of tea leaves moves left and right and starts to move to the top of the conical feeding mechanism 6-29 again, and the above operation is repeated;

[0071] Step D, the tea leaves start to be shaped, and the control system automatically calculates the optimal working parameters based on the standardized data in the database and starts to record the shaping data. During operation, the control system receives the data information obtained by the pressure, position sensor 6-41, pressure sensor 6-44, first temperature sensor 6-46, and humidity sensor 6-48 in real time for analysis, controls the working parameters of the shaping device in the current production and processing process, and uploads them to the control system at the same time; the control system collects the current pressure, position, temperature, and humidity in real time, and will continue to run if the exit condition is not triggered; when the temperature exceeds the specified temperature, the heating tube 6-45 is turned off; when the humidity exceeds the set humidity requirement, the dehumidifier 10 is turned on. When the tea leaves in the shaping machine reach the specified weight, they start to be shaped according to the optimal working parameters. When the shaping time is reached, the shaping degree is judged by the method of multi-morphological feature machine vision to judge whether the tea leaves meet the requirements for unloading. If the tea leaves meet the requirements, unloading begins; if the tea leaves do not meet the unloading requirements, processing continues until the method of multi-morphological feature machine vision determines that the shaping degree meets the requirements, then unloading begins. When the tea leaves start to be unloaded, the corresponding shaping machine starts to work, the motor drives the swing shaft 6-37 to start swinging, and the rubbing hand 6-39 installed on the swing shaft 6-37 swings back and forth on the rubbing plate 6-32. The tea leaves continue to move in the same direction under the action of the rubbing hand 6-39. The pressure cover 6-34 exerts pressure on the tea leaves as the connecting piece 6-42 swings. The excess tea leaves are scattered on both sides of the rubbing plate 6-32. Under the action of the swing plate 6-24 and the rotating plate 6-17, the tea leaves move back to the rubbing plate 6-32. After rubbing and kneading for many times, the tea leaves gradually form into strips. After the loading is completed, the shaping begins, and the original images of the tea leaves formed on both sides of the rubbing plate 6-32 are collected; the original images are read, and the ResNet-20 convolutional neural network model is constructed. The original images are used as input to determine whether the strip forming rate requirements are met. If the conditions are met, the unloading begins.

[0072] In the present invention, the swing shaft 6-37 moves, driving the swing plate 6-24 to move, and the swing plate 6-24 delivers the tea leaves that fall into the swing grooves 6-47 on both sides during the shaping process on the rubbing plate 6-32 into the sliding groove 6-18. The sliding groove 6-18 moves left and right, and the sliding groove 6-18 will move to the corresponding position of the rubbing plate 6-32, and enter the rubbing plate 6-32 under the action of the rotating plate 6-17. Because the sliding grooves 6-18 on both sides move left and right, the tea leaves in the swing grooves 6-18 on both sides can be alternately moved left and right. The rotation directions of the rotating shaft I 6-15 and the rotating shaft II 6-38 are opposite, so that the tea leaves that fall into the front and rear sliding grooves 6-18 can be delivered to the rubbing plate 6-32. In this process, the rubbing hands 6-39 rub forward, and the tea leaves in the rear sliding groove 6-18 are sent to the rubbing plate 6-32. When the rubbing hands 6-39 return to rub backward, the tea leaves in the front sliding groove 6-18 are sent to the rubbing plate 6-32 again, and this is repeated.

[0073] The steps for automatically calculating the optimal working parameters are as follows:

[0074] Step S1, data preprocessing, preprocessing the experience data of tea makers, eliminating the data of tea stripping rate and tea breakage rate that do not meet the standards of tea shaping machine, shuffling and normalizing the remaining data, and dividing the data set and the test set into 4:1 after normalization;

[0075] Step S2, model construction, taking tea variety, tea grade, leaf weight, and moisture content of tea before shaping as input, and taking shaping temperature, polishing temperature, shaping time, polishing time, pressurizing time, applied pressure, polishing speed, strip forming rate, and broken tea rate as output, to construct a 4-input 9-output particle swarm algorithm optimized long short-term memory neural network model; using the initial weights and thresholds of the long short-term memory neural network model optimized by the particle swarm algorithm, the evaluation functions selected in the cross-validation process of the model include determination coefficient, mean square error, mean absolute error, and mean absolute percentage error.

[0076] Step S3, parameter setting and model training, set the memory unit to 5, the number of hidden layers to 100, the activation function to sigmoid, the gradient descent optimization algorithm to Adam algorithm, the learning rate to 0.001, and the batch size to 32.

[0077] Step S4, model prediction.

The tea leaves were then rolled using a fine rolling machine which is currently widely used in production in Hubei Province. The temperature was 100°C to 110°C, the leaf amount was 4Kg to 5Kg, the time was 35min, and the moisture content of the tea leaves was controlled at 10% to 15% to obtain finely rolled leaves.

When the control system receives that the weight of the tea leaves in the cylinder (8-20) reaches the set weight, the cylinder (8-20) is controlled to rotate. 20) is reversed, and the tea leaves enter the mobile discharging system through the discharging port (8-16) on the cylinder; during the shaping process, the second temperature sensor (8-9) monitors the temperature of the cylinder (8-20) in real time, and when the temperature exceeds the set temperature of the control system, the heating is stopped; the temperature collected by the second temperature sensor (8-9) is compared with the set temperature, and the moisture content data calculated by the weight data collected by the weight sensor (8-7) installed on the cylinder (8-20) is compared with the moisture content set by the control system; when the control system receives the signal of the reversal of the cylinder (8-20), the motor III (7-8), the motor IV (7-9), and the fan II (7-10) on the mobile discharging system are controlled to start running, and the tea leaves fall onto the stainless steel mesh belt (7-3) for cooling, and are then transported to the next process.
