Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to an automatic sugar painting machine. Background Art

[0002] Sugar painting is a traditional folk handicraft. As the name suggests, it is a painting made of sugar. It is both sugar and painting, and can be seen and eaten. It is commonly known as "inverted sugar man", "inverted sugar cake" or "sugar lantern shadow". It is divided into two types: flat sugar painting and three-dimensional sugar painting.

[0003] The only tools used are a spoon and a spatula. The sugar is usually red and white sugar with a little maltose, which is boiled on a stove over a low heat. When it is boiled to the point where it can be stretched into threads, it can be used to cast the shape. When drawing the shape, the artist scoops up the melted sugar juice with a small spoon and quickly pours it back and forth on the stone slab to draw the shape. The folk artist's hand skills are the key to the shape. When the shape is completed, the sugar painting is scooped up with a small spatula and glued to a bamboo stick.

[0004] With the progress of society, science and technology have developed rapidly. Some manual techniques have gradually been replaced by machines, and sugar painting is no exception. In order to make the sugar paintings more standardized and hygienic, as well as more efficient, people have invented some sugar painting machines.

[0005] The existing application publication number is CN216886039U, and the invention patent named "A human-machine interactive intelligent sugar painting machine" records that it includes a box body, a manipulator, a sugar-feeding device, a drawing board and a control device are installed in the box body, the drawing board is installed below the sugar-feeding device, and the sugar-feeding device includes a sugar box, a sugar amount control mechanism, a heating mechanism and a rotating mechanism; the output end of the manipulator is connected to the sugar box, the sugar amount control mechanism is installed on the sugar box, the rotating mechanism is installed on the upper end of the sugar box, and a nozzle is installed at the lower end of the sugar box, and the nozzle is installed with the heating mechanism, one end of the sugar amount control mechanism extends into the sugar box and is connected to the output end of the rotating mechanism through a positioning pin, and the second end of the sugar amount control mechanism extends into the nozzle and is connected to the heating mechanism; the manipulator includes a mounting frame, a lifting mechanism and a moving mechanism, and the mounting frame is installed on the box body, which improves the stability of sugar feeding heating, reduces the failure rate and maintenance cost, is simple to operate, avoids syrup blockage and material waste, and also increases interactivity and fun, and better meets the needs of users.

[0006] However, according to the above content combined with the prior art, the main function of the tray structure of the central idea of ​​the solution recorded in the above patent is to be movable, and the overall stability is relatively high, which can achieve the effect of automatic discharging.

[0007] However, the above scheme has great defects in actual use. The above scheme is the same as the prior art, and its design scheme is mainly to control the coarseness and emergency stop effect of the syrup discharge, but it needs to be coordinated with a robot when in use, and the cost is relatively high. In addition, the robot occupies a large space. Therefore, the entire sugar painting machine is relatively large and inconvenient to carry, and the furnace head is relatively heavy as a whole. Long-term use will reduce the sensitivity of the robot, thereby reducing the effect of sugar painting, which does not meet people's use requirements. For this reason, we have developed an automatic sugar painting machine. Summary of the invention

[0008] 1. Technical issues to be resolved

[0009] In view of the deficiencies in the prior art, the present invention provides an automatic sugar painting machine, which improves the structure of the existing sugar painting machine so that its overall structure is stable, the force is evenly distributed, the accuracy decay rate is slow, and it can be used for a long time. In addition, its overall size is small and it is applicable to a wide range of scenarios. It can also automatically check the sugar painting effect and automatically remind relevant technicians to perform maintenance in time when the sugar painting effect is not good, which can help to better formulate maintenance plans. The overall use effect is good and it has a good prospect for use.

[0127] The air cooling component 5 adopts a fan component with a guide cover, which can directly guide the wind to blow onto the surface of the sugar painting. The fan component can also be further configured as an air cooler, and the cold wind blown out can reduce the temperature of the sugar painting more quickly.

[0128] The mobile pallet structure 2 includes a conveying device 21, a guide 22, a pallet structure 23 and an identification component 24:

[0156] The base is threadedly connected to the upper cylinder; wherein a heating component is installed inside the base.

[0157] This sugar painting machine is a basic sugar painting machine, which runs according to the set program.

[0158] The present invention records an automatic sugar painting machine, which improves the structure of the existing sugar painting machine so that its overall structure is stable, the force is evenly distributed, the accuracy decay rate is slow, and it can be used for a long time. In addition, its overall size is small and its applicable scenes are relatively wide. It can also automatically check the sugar painting effect and automatically remind relevant technical personnel to perform maintenance in time when the sugar painting effect is not good, which can help to better formulate maintenance plans. The overall use effect is good and has a good use prospect.

[0159] Example 2

[0160] On the basis of Example 1, Figure 1-10 As shown, this embodiment also records the following structure:

[0161] A camera assembly for acquiring image data of formed sugar paintings is embedded on the cover of the sugar painting machine body 1 .

[0162] When in use, the controller inside the sugar painting machine body 1 can be an industrial computer with a high operating speed, which directly calculates and processes data, or it can be provided with a controller with a wireless transmission function, which sends data to a server, and the server calculates the relevant data.

[0163] The controller receives the formed sugar painting picture data transmitted by the camera component and analyzes and processes it. The steps of judging the sugar painting effect are as follows:

[0164] The controller pre-processes the received image;

[0165] Grayscale the preprocessed image, and then extract the pixel positions whose grayscale values ​​are within the set grayscale range;

[0166] The formula for calculating the grayscale value of an image is as follows:

[0167] Gray=0.299×R+0.587×G+0.114×B

[0168] In the formula, Gray is the gray value of the pixel, R is the red value of the pixel, G is the green value of the pixel, and B is the blue value of the pixel;

[0169] Input the acquired pixel positions and the scale of the image into the coordinate system to construct a planar product image;

[0170] The sugar painting pattern data selected by the user is input into the same coordinate system and compared with the flat product image to calculate the pattern similarity.

[0171] The formula for calculating pattern similarity is as follows:

[0172]

[0173] Where Xs is the calculated pattern similarity, Scdtj is the overlap area between the sugar painting pattern data selected by the user and the flat product image, Sbztj is the area of ​​the sugar painting pattern data selected by the user, Sztj is the area of ​​the flat product image, jjxs is the influence coefficient of different seasonal environments on pattern similarity, 1≤jjxs≤1.1;

[0174] When 85%<Xs, no adjustment is made.

[0175] When Xs≤85%, the acquisition controller calculates the stability data and error data of each operation of the tray structure 23;

[0176] If the N groups of error data are all within the single error interval, and the stability data are within the stability interval, the lateral conveying device 11 is maintained;

[0177] If there are other conditions, further inspect the transverse conveying device 11 and the conveying assembly;

[0178] The error in sugar painting is mainly caused by abnormality in the conveying structure. The relevant conveying structures in this sugar painting machine are the transverse conveying device 11 and the conveying assembly. Therefore, it is necessary to analyze whether there is abnormality in the conveying assembly. If there is no abnormality, the transverse conveying device 11 should be maintained.

[0179] The reason why the lateral conveying device 11 is not provided with a corresponding detection structure is that the overall cost after the setting is relatively high.

[0180] The controller receives the image data of the mobile tray structure 2 transmitted by the camera assembly, and performs analysis and processing to determine whether there is stain on the support member of the mobile tray structure 2 as follows:

[0181] The controller pre-processes the received image;

[0182] Grayscale the preprocessed image and compare the maximum and minimum grayscale values ​​with the cleaning interval;

[0183] If the maximum and minimum grayscale values ​​are both within the cleaning range, no cleaning is required;

[0184] If the maximum or minimum grayscale value is outside the cleaning interval, cleaning is required.

[0185] When in use, cleaning can be achieved by directly replacing the support member. This method is fast in replacement speed and more convenient in cleaning.

[0186] Example 3

[0187] On the basis of Example 2, Figure 1-10 As shown, this embodiment also records the following structure:

[0188] A thermoelectric cooling sheet 25 for reducing the temperature of the finished sugar painting is installed at the lower end of the tray structure 23 near the identification component 24. The thermoelectric cooling sheet 25 can also be replaced by an existing water cooling structure. The thermoelectric cooling sheet 25 is mainly used to accelerate the temperature reduction speed of the finished sugar painting, thereby increasing the speed of sugar painting production. A temperature sensor for identifying the temperature of the tray structure 23 is installed on the tray structure 23. The temperature sensor is electrically connected to the thermoelectric cooling sheet 25 and is used to send a corresponding signal to the controller and the thermoelectric cooling sheet 25 when the temperature of the tray structure 23 reaches a set threshold.

[0189] After the sugar painting is made, the thermoelectric cooling sheet 25 is started to cool down. When the temperature sensor detects that the temperature of the tray structure 23 is lower than the threshold, a signal is sent to the controller and the thermoelectric cooling sheet 25, and the thermoelectric cooling sheet 25 stops working. At this time, the controller controls the conveying component to start, and the conveying component drives the tray structure 23 to move, so that the user can take out the finished sugar painting conveniently.

[0190] The present invention records an automatic sugar painting machine, which improves the tray structure 23 of the existing sugar painting machine so that the tray of the sugar painting machine has a bamboo stick recognition function, and as a prerequisite for the operation of the equipment, the entire equipment will not start until the bamboo stick is recognized, which can effectively prevent the bamboo stick from adhering to the mobile tray, and can effectively reduce the steps for staff to clean the sugar painting machine, with good use effect and good use prospects.

[0191] A calibration module for detecting the working status of the conveyor assembly is installed on the support plate to facilitate relevant technicians to understand the use status of the conveyor assembly and determine whether maintenance is required. The steps for calibrating the working status of the conveyor assembly with the calibration module are as follows:

[0192] Obtaining the position data of the initial state of the tray structure 23 A laser distance measuring instrument is installed at the rear end of the sugar painting machine, and the position data is the distance between the monitored tray structure 23 and the laser distance measuring instrument;

[0193] The controller of the sugar painting machine body 1 randomly extracts N groups of movement data and sends them to the conveying device 21, controls the conveying device 21 to drive the tray structure 23 to move, and collects the position data of the tray structure 23 after each movement into position;

[0194] Calculate the error data and stability data of each operation of the tray structure 23;

[0195] The formula for calculating the error data of each operation of the pallet structure 23 is as follows:

[0196]

[0197] Wherein, △D1 is the position error data generated by the first movement of the tray structure 23, △D Nis the position error data generated by the Nth movement of the pallet structure 23, Jcwz1 is the position data after the first movement of the pallet structure 23, Cswz is the initial position data of the pallet structure 23 detected, Yd1 is the first movement distance extracted, Jcwz N Yd is the position data after the Nth movement of the tray structure 23. N is the Nth moving distance extracted, Jcwz N-1 is the position data after the N-1th movement of the tray structure 23;

[0198] The larger the error data for each run, the worse the working condition of the conveying component.

[0199] The stability data is calculated as follows:

[0200]

[0201] Where Wcv is the calculated stability data;

[0202] The larger or smaller the calculated stability data is, the more unstable the data is, and the worse the working condition of the conveying component is.

[0203] Obtain the current environment data and calculate the corresponding adjustment interval under the environment data;

[0204] The adjustment interval includes a single error interval and a stability interval; the single error interval under the standard environment is -α, α, and the stability interval under the standard environment is -β, β;

[0205] Calculate the single error interval -α′ in the current environment. The formula for α′ is:

[0206]

[0207] In the formula, A and B are constant coefficients, and A>B>0, T j is the current ambient temperature detected, T b is the standard ambient temperature, RH j The current ambient humidity, RH b is the standard ambient humidity;

[0208] Calculate the stability interval -β′ in the current environment. The β′ formula is:

[0209]

[0210] In the formula, C and D are constant coefficients and C>D>1;

[0211] Affected by the external environment, the equipment will naturally produce certain errors.

[0212] Compare the error data and the comprehensive error data with the adjustment interval, and execute the corresponding adjustment strategy according to the adjustment interval;

[0213] The corresponding adjustment strategies are as follows according to the adjustment range:

[0214] When N groups of error data are all in the single error interval, and Wcv is in the stability interval, no adjustment is required, and the maintenance date is predicted, and a maintenance plan is formulated according to the maintenance date;

[0215] When the maintenance date is predicted, calculate the remaining stable use days T S , the remaining stable use days T calculated S satisfy:

[0216]

[0217] Where Wcv b is the stability data corresponding to the maintenance state, Wcv′ is the stability data of the last test, T z is the number of days corresponding to the detection cycle, and Dqyx is the impact coefficient of future environment on equipment loss;

[0218] When the error data is outside the single error interval, but Wcv is in the stability interval, the conveying assembly and the detection guide 22 are maintained;

[0219] When Wcv is in the stable zone, directly replace the conveying component.

[0220] The present invention records an automatic sugar painting machine, which improves the existing automatic sugar painting machine so that it has a calibration function and can clearly display the working status of a conveying component. Through the working status of the conveying component, it can be directly judged whether the machine can accurately produce sugar paintings and ensure the effect of sugar paintings. The maintenance time of the equipment can be further predicted, which is convenient for corresponding staff to formulate maintenance plans. The overall use effect is good and the machine has a good prospect of use.

[0221] Example 4

[0222] This embodiment is based on the embodiment 3. Figure 1-10 As shown, the following structures are also included:

[0223] The heating component adopts a heating plate 331, and an electric heating wire is arranged inside the heating plate 331. The heating plate 331 is arranged inside the base, and a weighing component connected to the controller of the sugar painting machine body 1 is fixedly installed at the lower end of the heating plate 331 on the base;

[0224] An annular ring 322 is installed near the middle position inside the upper cylinder, and a plurality of groups of weighing sensors 323 connected to the controller of the sugar painting machine body 1 are arranged at equal intervals on the upper end surface of the annular ring 322 near the outer position, which are used to send a warning signal when the sugar amount reaches the lower limit. A storage tray 321 is arranged on the upper end surface of the weighing sensor 323, and a solenoid valve 324 connected to the controller of the sugar painting machine body 1 is installed on the unloading port of the storage tray 321. A lever 325 for stirring the flow of sugar is arranged on the outer surface of the spiral rod 312 near the upper end.

[0225] During use, the spiral rod 312 drives the lever 325 to rotate, so that the lever 325 can evenly move the sugar on the storage tray 321, thereby facilitating the sugar to flow out through the solenoid valve 324 next time.

[0226] The present invention records an automatic sugar painting machine, which improves the furnace head structure 3 of the existing sugar painting machine so that the heating furnace head 3 of the sugar painting machine can work at a low voltage, greatly improving the safety performance of the entire heating furnace head and having a good use prospect.

[0227] The steps of the weighing component, the solenoid valve 324 and the controller of the sugar painting machine body 1 to achieve accurate batching are as follows:

[0228] Obtain the sugar painting pattern that needs to be made selected by the user;

[0229] You can scan the QR code entered on the sugar painting machine to enter the database, or you can upload the pattern separately. The following are the steps for making sugar paintings by uploading patterns;

[0230] Scan the sugar painting pattern to take a flat photo of the pattern with clear lines, and enter the sugar painting pattern into the 3D software;

[0231] The three-dimensional software can be CAD or other software, and the input pattern is in the form of lines;

[0232] Enlarge the sugar painting pattern to the size required by the user, and obtain the circumference corresponding to the sugar painting pattern;

[0233] Calculate the required amount of sugar and weigh the comparison data according to the circumference of the sugar painting pattern;

[0234] The formula for calculating the amount of sugar required based on the circumference of the sugar painting pattern is as follows:

[0235]

[0236] Where, T l is the required amount of sugar, C is the perimeter of the enlarged sugar painting pattern, Zhxs is the conversion coefficient, ε and e are both constant coefficients, ε is greater than 1, T j is the current ambient temperature detected, T b is the standard ambient temperature, RHj The current ambient humidity, RH b is the standard ambient humidity, Qtxs is the weight coefficient of the influence of ambient temperature on sugar weight, and Qrxs is the weight coefficient of the influence of ambient humidity on sugar weight;

[0237] The controller of the sugar painting machine body 1 starts the solenoid valve 324, and the solenoid valve 324 opens, so that the sugar passes through the solenoid valve 324 and falls onto the storage tray 321;

[0238] The weighing assembly weighs and feeds back the weight data to the controller of the sugar painting machine body 1, and when the weight data is greater than or equal to the weighing comparison data, the solenoid valve 324 is closed;

[0239] After the electromagnetic valve 324 is closed, the controller of the sugar painting machine body 1 obtains the weighing data of the weighing sensor 323 and the weighing assembly, calculates the data difference, compares the data difference with the calibration interval, and executes the corresponding calibration strategy according to the comparison result;

[0240] The formula for calculating the difference between the weighing data of the weighing sensor 323 and the weighing data of the weighing assembly is as follows:

[0241]

[0242] Among them, CZ zl is the difference between the weighing data of the weighing sensor 323 and the weighing data of the weighing assembly, Wcxs is the error coefficient of the weighing sensor 323 of group K, gc i is the weighing data of the i-th weighing sensor 323, gc j is the weighing data of the weighing component;

[0243] When CZ zl Maintain or replace the weighing component when it is outside the calibration range;

[0244] The formula for calculating weighing comparison data is as follows:

[0245] Bdcz=T l +CZ′ zl

[0246] In the formula, Bdcz is the weighing comparison data, CZ′ zl It is the difference of weighing data detected when the sugar painting machine was used last time.

[0247] The present invention records an automatic sugar painting machine, which processes and analyzes the sugar painting to be made, calculates the amount of sugar needed to make the sugar painting, and then melts the required amount of sugar to make the sugar painting. The machine can effectively avoid the situation where the sugar is melted repeatedly, the sugar is heated multiple times due to long usage times, and the sugar painting produced is prone to being burnt and bitter, so that the sugar painting has a better edible taste. The machine also has a monitoring function, which can realize the monitoring and early warning of the sugar amount and the calibration of the sensor, helping relevant technical personnel to better manage, and has a good prospect of use.

[0248] The weight coefficient is determined by the coefficient of variation method, which is a method of weighting each indicator according to the degree of variation between the current value of each evaluation indicator and the target value. If the numerical difference of an indicator is large, it can clearly distinguish the evaluated objects, indicating that the indicator has rich discrimination information, and thus the indicator should be given a larger weight. On the contrary, if the numerical difference of each evaluated object on a certain indicator is small, then the ability of this indicator to distinguish the evaluation objects is weak, and thus the indicator should be given a smaller weight. This method directly uses the information contained in each indicator and obtains the weight of the indicator through calculation, so it is objective.
