Description
Technical Field
[0001] The utility model relates to the technical field of betel nut raw fruit sorting, in particular to a betel nut raw fruit sorting device. Background Art
[0002] At present, the betel nut food manufacturing industry is still a labor-intensive industry. Most of the processes need to be completed manually. The lack of labor and the increase in labor costs have become the biggest bottleneck in the development of the betel nut industry. This has put forward an urgent need for the automated production of betel nut food. The quality of betel nut seeds directly determines the taste and quality of betel nut food. In the processing and production of betel nut, sorting betel nut seeds is the first step and a crucial step. Whether it is green fruit or smoked fruit, betel nut seeds need to be sorted and graded according to the size, surface texture and other characteristics of betel nut seeds to ensure that the processed betel nut products have a good quality grade. However, what really determines the taste is the quality of the betel nut seeds. What is important is not the external size, but the wall thickness of the betel nut. There is basically no detection of betel nut wall thickness in the domestic market. Currently, the detection and screening of betel nut is mainly through camera photography to identify the appearance and size of the betel nut, as well as texture classification. There is no identification and sorting of the internal structure of the betel nut. However, from the perspective of consumers, they chew betel nut mainly based on the wall thickness of the betel nut. If the wall thickness of the betel nut is too thick, it will be difficult to chew. If the wall thickness of the betel nut is too thin, it will feel a bit prickly when chewing. Thickness is an important factor affecting the taste for consumers, and there is almost no detection equipment for the thickness of betel nut. Therefore, we designed and developed equipment for betel nut wall thickness detection. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects: the betel nut raw fruit sorting equipment is manually loaded, and the betel nuts are poured into the hopper. As the chain plate conveyor line assembly rotates, the betel nuts move forward. At the same time, there is a dust cover connected to the blower directly below the chain plate conveyor line assembly, which sucks the dust in the betel nuts and sucks it into the dust bag of the blower through the small holes of the chain plate conveyor line assembly. The betel nuts with dust removed continue to move forward with the chain plate conveyor line assembly and fall forward into the vibration disk assembly. The vibration disk assembly is composed of a vibration body and a vibration disk assembly made of sheet metal. The betel nuts slowly move forward in the vibration disk assembly through the vibration of the vibration body. The vibration disk assembly has two levels. The first stage is connected to the chain plate conveyor line assembly, the second stage is connected to the first stage vibration plate assembly and the lower stage is connected to the acceleration conveyor line. The betel nut falls into the second stage vibration sheet metal through the first stage vibration sheet metal, and then falls into the acceleration conveyor line assembly from the second stage vibration sheet metal. The betel nut is accelerated on the acceleration conveyor line assembly to improve efficiency. The accelerated betel nut falls into the six main conveyor line assemblies. The betel nut moves along the conveyor line to the bottom of the X-ray machine detection assembly. The X-ray machine detection assembly takes a photo of the moving betel nut and calculates the wall thickness and length of the betel nut through the program, and displays the value on the display screen. At the same time, it gives a signal to which level the betel nut wall thickness belongs to the high-frequency solenoid valve behind it. The betel nut passes the X-ray machine inspection After the measuring component passes through the sensor, the X-ray machine transmitter takes a picture of the betel nut moving directly below, and the receiver calculates its actual size on the software based on the size of the betel nut projection. The principle of recognition is similar to that of the hospital's filming. The actual size is calculated and then the betel nut is divided into grades according to its wall thickness, length, and width, and the divided results are given to the PLC. After the betel nut passes through the through-beam sensor, the sensor gives a position signal to the PLC. The two signals are combined to determine the blowing time, which is given by the PLC to the solenoid valve. The high-frequency solenoid valve controls the on and off of the air. After receiving the signal, the high-frequency solenoid valve is electrically attracted, and the blowing block starts to blow air to make the betel nut fall. After blowing for a period of time, the high-frequency solenoid valve is turned on and off. The high-frequency solenoid valve is powered off and the gas supply is disconnected, the blowing block stops blowing, and the sensor detects the presence of betel nut and gives a signal of the high-frequency solenoid valve blowing time. The two signals work together to make the high-frequency solenoid valve blow the betel nut off at the exact wall thickness level and at the exact time. The blown-off betel nut falls onto the four-channel discharging conveyor line assembly. The four-channel discharging conveyor line assembly is divided into four different wall thickness grades of betel nut. The conveyor line brings together betel nuts of the same wall thickness grade for easy collection. Betel nuts that are not identified or do not meet any wall thickness grade will be transported to the reflux hopper at the back by the six main conveyor line assemblies, and then collected into the collection basket. At this point, the entire betel nut wall thickness detection is completed. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Specifically, a sheet metal frame 78 is installed on the equipment frame 1, a through-beam sensor 79 is installed on the equipment frame 1, multiple groups of rollers 80 are installed on the equipment frame 1, a blow box bracket 81, a gas storage tank 82 and a diversion gas exhaust 83 are installed on the equipment frame 1, a guide welding plate 84 is installed on the equipment frame 1, a Foma wheel 85 is provided on the bottom side of the equipment frame 1, and multiple welding drawers 86 are provided on one side of the equipment frame 1. A pneumatic triplet 87, a safety valve 88 and a pressure gauge 89 are installed on the equipment frame 1. All the mechanism components of the equipment frame 1 are installed on this sheet metal frame 78, and rollers 80 and guide welding plates 84 are installed on the frame. The rollers 80 are convenient for easier insertion and removal of the six main conveyor line components 6 during assembly and disassembly. The guide welding plate 84 is to play a positioning and guiding role in assembling the conveyor belt, which is convenient for assembly and positioning. Device 79 senses the presence of betel nut when it passes by and gives a signal of the blowing position to the high-frequency solenoid valve 38. The welding drawer 86 is for the convenience of cleaning the residual betel nut in the equipment and for easy cleaning. The pneumatic triplet 87 is a transition component that transfers the total gas from the customer to the equipment, and plays the role of pressure regulation for filtering and drying. The total gas passes through the triplet to the gas tank 82, and the gas tank 82 supplies gas to the entire equipment. The X-ray machine part needs to be blown all the time to dissipate heat, and the gas consumption is relatively large. The diversion air exhaust 83 is a blowing mechanism that receives air from the gas tank 82 and distributes it to the six main conveyor line components 6 above. The safety valve 88 ensures that the maximum pressure of the gas tank 82 does not exceed a certain value, and plays a protective role for the pneumatic components of the equipment. The pressure gauge 89 can see the pressure of the gas tank 82 in real time to ensure that the air pressure of the equipment is normal. The Fomar wheel 85 at the bottom of the sheet metal frame 78 is for the convenience of moving the equipment.
[0044] During use: manual loading, pour the betel nuts into the hopper 2, and as the chain plate conveyor line assembly 3 rotates, the betel nuts move forward. At the same time, there will be a dust cover 18 connected to the blower 20 directly below the chain plate conveyor line assembly 3, which will suck the dust in the betel nuts and suck it into the dust bag of the blower 20 through the small holes of the chain plate conveyor line assembly 3. The betel nuts with dust removed will continue to move forward with the chain plate conveyor line assembly 3 and fall forward into the vibration disk assembly 4. The vibration disk assembly 4 is composed of a vibrating body 21 and a vibration disk assembly 4 made of sheet metal. The betel nuts move slowly forward in the vibration disk assembly 4 through the vibration of the vibrating body 21. The vibration disk assembly 4 has two stages, and the first stage is connected to the chain plate conveyor line assembly 3. The second stage is connected to the first stage vibration plate assembly 4 at the top and the acceleration conveyor line at the bottom. The betel nut falls into the second stage vibration plate metal 23 through the first stage vibration plate metal 22, and then falls into the acceleration conveyor line assembly 5 from the second stage vibration plate metal 23. The betel nut is accelerated on the acceleration conveyor line assembly 5 to improve efficiency. The accelerated betel nut falls into the six main conveyor line assemblies 6. The betel nut moves along the conveyor line to the bottom of the X-ray machine detection assembly 7. The X-ray machine detection assembly 7 takes a photo to identify the moving betel nut, calculates the wall thickness and length of the betel nut through the program, and displays the value on the display screen 56. At the same time, a signal is given by the high-frequency electromagnetic valve 38 at the back to indicate which level the betel nut wall thickness belongs to. After the betel nut passes through the X-ray machine detection assembly 7 After passing through the sensor, the X-ray machine transmitter 69 takes a picture of the betel nut moving directly below, and the receiver 65 calculates its actual size on the software based on the size of the betel nut projection. The recognition principle is similar to that of the hospital's filming. The actual size is calculated and then the betel nut is divided into grades according to its wall thickness, length, and width, and the divided results are given to the PLC. After the betel nut passes through the through-beam sensor 79, the sensor gives a position signal to the PLC. The two signals are combined to determine the blowing time, which is given by the PLC to the solenoid valve. The high-frequency solenoid valve 38 controls the on and off of the air. After receiving the signal, the high-frequency solenoid valve 38 is electrically attracted, and the blowing block starts to blow air to make the betel nut fall. After blowing for a period of time, the high-frequency solenoid valve 38 is turned on and off. The valve 38 is powered off to disconnect the gas supply, and the blowing block stops blowing. When the sensor detects the presence of betel nut, it gives a signal of the blowing time of the high-frequency solenoid valve 38. The two signals work together to make the high-frequency solenoid valve 38 blow the betel nut off at the exact wall thickness level and at the exact time. The blown-off betel nut falls onto the four-channel discharging conveyor line assembly 8. The four-channel discharging conveyor line assembly 8 is divided into four types of betel nuts with different wall thickness levels. The conveyor line brings together betel nuts of the same wall thickness level for easy collection. Betel nuts that are not identified or do not meet any wall thickness level will be transported to the reflux hopper 36 at the back by the six main conveyor line assemblies 6, and then collected into the collection basket. At this point, the entire betel nut wall thickness detection is completed.
