Abstract
Description
Technical Field
[0001] This utility model relates to the field of glutinous rice ball processing, and in particular to a frozen glutinous rice ball identification and sorting device. Background Technology
[0002] In the food processing industry, especially in the production of traditional foods such as glutinous rice balls, quality inspection and sorting of glutinous rice balls is an important task. Traditional sorting methods mainly rely on manual labor, visually identifying whether the glutinous rice balls are defective, and then sifting out the defective ones, leaving only the intact ones. However, this method is inefficient and easily affected by human factors, resulting in low sorting accuracy.
[0003] In existing technologies, there are also methods for screening glutinous rice balls based on their diameter. For example, a glutinous rice ball machine disclosed in application number CN201822241897.3 includes a glutinous rice ball outlet, and a screening device is provided outside the outlet. The screening device includes two screening plates arranged vertically, namely an upper screening plate and a lower screening plate, with a gap between the two screening plates. Both screening plates are composed of several parallel crossbars, and there is a certain gap between adjacent crossbars. Although this method of screening based on the diameter of the glutinous rice balls can ensure the uniformity of the size of the glutinous rice balls, it cannot accurately identify broken glutinous rice balls, and the debris cannot be removed during sorting. Therefore, this solution proposes a frozen glutinous rice ball identification and sorting device. Utility Model Content
[0004] This invention proposes a frozen glutinous rice ball identification and sorting device, which solves the problem that existing glutinous rice ball screening devices cannot accurately screen out glutinous rice balls that are not up to standard.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A frozen glutinous rice ball identification and sorting device includes a frame, on which a feeding device, a conveying device, an identification device and a rejection device are installed, and the rejection device is connected to the output end of the identification device.
[0007] The feeding device includes a screen vibrating feeder mounted on the frame, a buffer hopper located directly above the screen vibrating feeder, and a receiving hopper located directly below the screen vibrating feeder.
[0008] The conveying device is located at the front end of the feeding device, and the conveying device includes a crescent-shaped conveyor belt mounted on the frame and a drive motor mounted on the frame for driving the crescent-shaped conveyor belt to rotate.
[0009] The identification device includes a processing device mounted on a rack and a first identification component and a second identification component electrically connected thereto. The first identification component is located above the front end of the conveying device, and the second identification component is located below the front end of the conveying device.
[0010] The rejection device is located at the lower front of the conveying device and is electrically connected to the identification device. The rejection device includes an air nozzle and an air nozzle control device. The air nozzle is arranged in multiple rows and is located at the front end of the conveying device.
[0011] The above technical solution not only allows for the convenient and quick removal of substandard glutinous rice balls, but also facilitates the quick removal of broken pieces from the glutinous rice balls, preventing subsequent debris from adhering to the surface of the glutinous rice balls.
[0012] As a further improvement to the above solution, the crescent-patterned conveyor belt is a conveyor belt with multiple arc-shaped crescent patterns uniformly fixed on its surface.
[0013] Through the above technical solution, the design of the crescent-shaped pattern can not only stably support the glutinous rice balls, but also effectively prevent them from sliding or rolling during transportation.
[0014] As a further improvement to the above solution, the first identification component includes a first high-definition camera, the second identification component includes a second high-definition camera, and both the first high-definition camera and the second identification component are electrically connected to the processing device.
[0015] As a further improvement to the above scheme, both the first identification component and the second identification component are spaced apart from the rejection device.
[0016] As a further improvement to the above solution, the air nozzle control device is electrically connected to the high-definition camera.
[0017] As a further improvement to the above solution, a material distribution device is also included, located directly below the rejection device. The material distribution device is mounted on the frame and includes a material distribution hopper and a material guiding conveyor belt. The material distribution hopper includes two hoppers arranged sequentially from back to front: a finished glutinous rice ball hopper and a defective glutinous rice ball hopper. The material guiding conveyor belt includes a first conveyor belt and a second conveyor belt. The first conveyor belt is located directly below the finished glutinous rice ball hopper, and the second conveyor belt is located directly below the defective glutinous rice ball hopper.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. The selected glutinous rice balls are fed through a feeding device and then conveyed to an identification device for inspection. The identification device outputs a classification signal based on the inspection results. A rejection device then blows off glutinous rice balls that do not meet the standards, such as those with discoloration, irregular shape, or missing filling. These non-compliant glutinous rice balls are then collected in a defective hopper within a sorting device, while compliant glutinous rice balls continue to fall into a finished product hopper. Two conveyor belts then transport both non-compliant and finished glutinous rice balls to designated locations, thus accurately removing glutinous rice balls with poor appearance and improving work efficiency.
[0020] 2. By setting up a vibrating screen feeder, the debris in the glutinous rice ball material can be removed first, and the glutinous rice balls can be preliminarily screened and cleaned to prevent debris from sticking to the surface of the glutinous rice balls later.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0030] Example 1:
[0031] Please combine Figure 1 - Figure 6 The frozen glutinous rice ball identification and sorting device of this embodiment includes a frame 1, on which a feeding device 2, a conveying device 3, an identification device 4 and a rejection device 5 are installed, and the rejection device 5 is connected to the output end of the identification device 4.
[0032] The feeding device is located on the frame 1 and is mainly used to carry the selected glutinous rice balls. Specifically, the feeding device 2 includes a screen vibrating feeder 201 installed on the frame 1, a buffer hopper 202 located directly above the screen vibrating feeder 201, and a receiving hopper 203 located directly below the screen vibrating feeder 201. The buffer hopper 202 is set to prevent the glutinous rice balls from being blocked or piled up during the conveying process, so that the material is efficiently and orderly fed evenly to the screen vibrating feeder 201 for screening out the debris.
[0033] Furthermore, the glutinous rice balls in the buffer hopper 202 enter the vibrating screen feeder 201. The vibrating screen feeder 201 can not only evenly feed the glutinous rice balls onto the conveying device 3, but also remove the debris from the glutinous rice balls, performing preliminary screening and cleaning. The debris removed by the vibrating screen feeder 201 enters the receiving hopper 203 located below it for collection, and the screened glutinous rice balls continue to enter the conveying device 3.
[0034] The conveying device 3 is located at the front end of the feeding device 2, and the conveying device 3 includes a crescent-shaped conveyor belt 301 mounted on the frame 1 and a transmission motor mounted on the frame 1 for driving the crescent-shaped conveyor belt 301 to rotate. Under the drive of the transmission motor, the crescent-shaped conveyor belt 301 is driven to rotate forward evenly, so that the glutinous rice balls falling on the top surface of the crescent-shaped conveyor belt 301 can be sent forward at a preset speed.
[0035] The crescent-patterned conveyor belt 301 is a conveyor belt with multiple arc-shaped crescent patterns evenly fixed on its surface. The arc-shaped crescent pattern design can not only stably support the glutinous rice balls, but also effectively prevent the glutinous rice balls from sliding or rolling during the conveying process, thereby ensuring the accuracy and stability of the conveying, so as to facilitate subsequent identification and rejection operations.
[0036] The identification device 4 includes a processing device mounted on the frame 1 and a first identification component 401 and a second identification component 402 electrically connected thereto. The first identification component 401 is located above the front end of the conveying device 3, and the second identification component 402 is located below the front end of the conveying device 3. The first identification component 401 includes a first high-definition camera 411, and the second identification component 402 includes a second high-definition camera 421. Both the first high-definition camera 411 and the second identification component 402 are electrically connected to the processing device. The processing device is equipped with an algorithm processing system that compares and judges the quality of the glutinous rice balls through an AI model. If defective glutinous rice balls with different colors, shapes, or filling are found, the identification device will output a corresponding classification signal. The high-definition camera detects the glutinous rice ball materials to be selected conveyed by the conveying device and outputs a classification signal based on the detection result. The processing device can be a conventional control unit such as an industrial control computer, PLC, or embedded system commonly used in the field.
[0037] The rejection device 5 is located in front of and below the conveying device 3 and is electrically connected to the identification device 4. The rejection device 5 includes an air nozzle 501 and an air nozzle control device 502. The air nozzle 501 is arranged in multiple rows and is located at the front end of the conveying device 3. The air nozzle control device 502 is electrically connected to a high-definition camera. According to the classification signal of the identification device 4, the rejection device 5 blows off the non-compliant glutinous rice balls by blowing air, thereby separating the qualified glutinous rice balls from the unqualified glutinous rice balls.
[0038] The first identification component 401 and the second identification component 402 are both spaced apart from the rejection device 5, which can effectively prevent the fragments from splashing up during the rejection of the glutinous rice balls and affecting the recognition function of the high-definition camera.
[0039] In this embodiment, after the AI model is trained, the algorithm processing system first needs to collect data, acquiring images of irregularly shaped, damaged, and exposed dumplings under different angles, heights, and brightness conditions. The second step is data preprocessing, which involves preprocessing the collected image data, including but not limited to image scaling, cropping, grayscale conversion, or colorization. Brightness adjustment and contrast enhancement can also be performed to improve the robustness of the model. The third step is data labeling, adding labels or category information to the image data so that the model can learn and distinguish different categories of images during training. The fourth step is model training, using the labeled image data to train the convolutional neural network model. During training, the convolutional neural network model will learn the mapping relationship between the input image and the output category label. Backpropagation algorithm and optimizer can be used during training to adjust the model's weights and biases to minimize prediction errors.
[0040] Furthermore, after model training is completed, model evaluation is performed using another set of labeled test data. The model is evaluated by calculating metrics such as accuracy, recall, and precision to assess its performance on the recognition task. If the model's performance does not meet the requirements, adjustments can be made to the model architecture, the amount of training data, or hyperparameter tuning. After evaluation, the model is deployed and applied. After training and evaluation are completed, the convolutional neural network model is deployed to the actual application scenario, that is, the convolutional neural network model is integrated into the software system so that users can input images and obtain recognition results.
[0041] Example 2:
[0042] Combination Figure 1 - Figure 3 This embodiment, based on embodiment 1, further improves upon the following: it also includes a material distribution device 6 located directly below the rejection device 5. The material distribution device 6 is mounted on the frame 1 and includes a material distribution hopper 601 and a guiding conveyor belt 602. The material distribution hopper 601 includes two hoppers arranged sequentially from back to front: a finished glutinous rice ball hopper 611 and a defective glutinous rice ball hopper 612. The guiding conveyor belt 602 includes a first conveyor belt 621 and a second conveyor belt 622. The first conveyor belt 621 is located near the finished glutinous rice balls. Directly below the feeding hopper 611, the second conveyor belt 622 is located directly below the defective glutinous rice ball feeding hopper 612. Glutinous rice balls that do not meet the standards, blown off by the air outlet, will fall into the defective glutinous rice ball feeding hopper 612 and then onto the second conveyor belt 622. Glutinous rice balls that meet the standards will continue to move and fall into the finished glutinous rice ball feeding hopper 611, and then be discharged onto the first conveyor belt 621. The first conveyor belt 621 and the second conveyor belt 622 will then respectively transport the qualified and unqualified glutinous rice balls to their designated locations.
[0043] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
