Description

Technical Field

[0001] The present invention relates to the technical field of food detection, and in particular to a multi-station detection device and method for food detection. Background Art

[0002] During the food production process, various tests and analyses are required to ensure that the quality and safety of food meet the requirements of laws and standards. During food testing, the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products is inspected based on the basic theories and various technologies of physics, chemistry and biology and in accordance with the technical indicators formulated by the state. Among them, when conducting physical inspection, optical means are sometimes used for inspection. Inspection light is emitted to the food to be inspected. Using the principle of light absorption and emission, the chemical composition, concentration, temperature, etc. of the object can be determined by measuring the absorption intensity and emission spectrum of light. The operation is simple and the degree of intelligence is high. However, in actual work, before optical inspection, the food to be inspected needs to be manually flattened to reduce the occurrence of food stacking, thereby maintaining the accuracy of subsequent inspection results. In addition, during inspection, the food to be inspected is in a stationary state. When using optical inspection, especially for some harder foods, the inspection mainly uses light scattering, which will have certain detection blind spots. Moreover, for some harder foods, optical inspection cannot detect the firmness of the hard shell of the food, and manual pressing inspection is required, which is time-consuming and labor-intensive, and the overall workload is large. Moreover, when food is inspected, a certain amount of residue will remain on the conveyor belt. These residues cannot be cleaned in time, which will affect the subsequent inspection results.

Secondly, there are multiple transmitters 8 and receivers 9, and one transmitter 8 and one receiver 9 are opposite to each other. The transmitter 8 can emit detection light, and the receiver 9 can detect the intensity of the detection light after the detection light is absorbed by the food to be detected. When food detection is required, the food to be detected is placed on the conveyor belt 5, and the motor 6 is started. The motor 6 drives the conveyor rod 3 to rotate, the conveyor rod 3 drives the conveyor roller 4 to rotate, and the conveyor roller 4 drives the conveyor belt 5 to move, and the transmission The conveyor belt 5 drives the food placed on its upper side through the housing 1, that is, through the working area of the transmitter 8 and the receiver 9. Secondly, a display screen is installed on the outer surface of the housing 1, and the receiver 9 can transmit the measured data to the display screen. After the food passes through the working area of the transmitter 8 and the receiver 9, the receiver 9 transmits the obtained data to the display screen. The staff can make judgments based on the obtained data and then complete the inspection operation of the food placed on the upper side of the conveyor belt 5. Then, unqualified food is picked out, and finally the overall food inspection operation is completed. The above are all existing technologies and no redundant description is given. In addition, before the above work, the position of the flattening plate 13 is adjusted according to the size of the food to be tested, and the first threaded rod 17 is rotated. Under the restriction of the telescopic sleeve 18, the rotating first threaded rod 17 will drive the movable plate 12 to move up and down relative to the shell 1, and the movable plate 12 drives the flattening plate 13 to move up and down until the distance between the flattening plate 13 and the conveyor belt 5 meets the working needs, that is, the distance between the flattening plate 13 and the conveyor belt 5 is between the size diameter of one food to be tested and the size diameter of two foods to be tested. When the food to be tested placed on the upper side of the conveyor belt 5 moves to the outside of the flattening plate 13, under the action of the flattening plate 13, the possibility of multiple foods to be tested piling up can be reduced. At the same time, under the action of the first pulley assembly 10, the rotating rod 7 will be caused to move. The rotating rod 7 drives the reciprocating screw 14 to rotate. Since the reciprocating screw 14 and the reciprocating wire sleeve 11 are threadedly connected, and under the limiting action of the positioning rod 15, when the reciprocating screw 14 rotates following the rotating rod 7, the reciprocating wire sleeve 11 will move back and forth along the positioning rod 15. The reciprocating wire sleeve 11 drives the movable plate 12 to move back and forth through the fixed plate 16 and the telescopic sleeve 18. The movable plate 12 drives the flattening plate 13 to move back and forth. Under the action of the flattening plate 13, it can not only form a limiting effect on the food to be tested, but also reduce the possibility of the food to be tested piling up. When there is a lot of food to be tested on the outside of the flattening plate 13, under the action of the flattening plate 13 moving back and forth, the food to be tested can be moved along the flattening plate 13, thereby forming a flattening effect on the food, which provides convenience for subsequent detection operations.

[0016] like Figure 6 、 Figure 9A separation assembly is installed on the lower side of the tiling plate 13, and the separation assembly includes two fixed frames 20 fixedly installed on the lower side of the movable plate 12. The two fixed frames 20 are slidably connected to a slide plate 19. A cross groove 28 is opened on the side wall of the slide plate 19. A first connecting plate 30 is slidably connected in the cross groove 28. The side wall of the first connecting plate 30 is threadedly connected to a second threaded rod 33. The outer side of the second threaded rod 33 is rotatably connected to a limit plate 27. A plurality of positioning plates 26 are evenly fixedly connected to the outer side of the slide plate 19. A pointed plate 21 is fixedly connected to the lower side of the first connecting plate 30. The second threaded rod 33 is rotated to move the second threaded rod 33 away from the first connecting plate 30, and the second threaded rod 33 drives the limit plate 27 to move until the limit plate 27 and the positioning plate 26 are disconnected. Then, the first connecting plate 30 is moved along the cross groove 28, and the first connecting plate 30 drives the pointed plate 21 to move until the position of the pointed plate 21 meets the working requirements. The second threaded rod 33 is rotated again, and the second threaded rod 33 drives the limit plate 27 to move until the limit plate 27 moves to between the two adjacent positioning plates 26, thereby completing the adjustment and fixing operation of the position of the pointed plate 21. Then, after the food to be inspected passes through the flat plate 13, under the action of the pointed plate 21, the food to be inspected can be separated, the spacing of the food to be inspected can be expanded, and the food to be inspected can be better inspected.

[0017] like Figure 7 、 Figure 8 、 Figure 10 、 Figure 11A processing assembly is installed on the outside of the pointed plate 21. The processing assembly includes two square plates 32. The side walls of the two square plates 32 are rotatably connected to the first connecting rod 34. The side wall of the first connecting rod 34 is slidably connected to the side wall of the snap ring 37. One side of the snap ring 37 is fixedly connected to the clamping rod 35. The side walls of the two square plates 32 are circumferentially provided with a plurality of clamping grooves 36. The clamping rod 35 and the clamping groove 36 are opposite. The side wall of the snap ring 37 is also fixedly connected to the first spring 38. A through slot 31 is provided on the side wall of each pointed plate 21. A transmission rod 29 is rotatably connected in the through slot 31. The outer side of the transmission rod 29 is fixedly connected to the connecting gear 40. There are limit positions on both sides of the through slot 31. Slot 42, both limiting slots 42 are slidably connected with limiting blocks 44, the outer side of the limiting block 44 is fixedly connected with a connecting rack 41, the connecting rack 41 is meshed with the connecting gear 40, a second spring 43 is fixedly connected between the limiting block 44 and the side wall of the limiting slot 42, one of the first connecting rods 34 is fixedly connected to the connecting rack 41, and the other first connecting rod 34 is fixedly connected to the other connecting rack 41 through a right-angle plate 39, one end of the transmission rod 29 is fixedly connected to the control plate 24, a plurality of control rods 25 are fixedly connected to the outer circumference of the control plate 24, and a plurality of fixed rods 23 are evenly fixedly connected to the lower side of the movable plate 12; First, before performing food inspection, adjust the angle between the square plate 32 and the first connecting rod 34 according to actual work needs. When the square plate 32 is needed to knock the food to be inspected, the square plate 32 and the through slot 31 should be in a vertical state (i.e. Figure 11 When the square plate 32 is needed to flip the food to be tested or to displace the food to be tested, there should be a certain angle between the square plate 32 and the through slot 31, and when the square plate 32 moves, the outer surface of the square plate 32 can be against the food to be tested, so that the food to be tested can be moved. In the above process, when the square plate 32 needs to be adjusted, the snap ring 37 is first moved away from the square plate 32, so that the snap ring 37 compresses the first spring 38, and the snap ring 37 drives the clamping rod 35 to move until the clamping rod 35 is removed from the clamping slot 36, and then the square plate is rotated around the first connecting rod 34. 32, until the position of the square plate 32 meets the working needs, and then the snap ring 37 is loosened. At this time, under the action of the first spring 38, the clamping rod 35 enters the corresponding clamping groove 36, thereby completing the adjustment and fixing operation of the square plate 32. Then, when performing the food testing operation, when the movable plate 12 and the flattening plate 13 move back and forth, since the slide plate 19 and the inner wall of the shell 1 are abutted and connected to the shell 1 for sliding up and down, the movable plate 12 moving back and forth will drive the fixed rod 23 to move back and forth relative to the slide plate 19. When the fixed rod 23 and the control rod 25 are abutted, the control rod 25 and the control plate 24 will be driven to rotate around the transmission rod 29 as the center, so as to Figure 8When the movable plate 12 drives the fixed rod 23 to move to the upper right, the fixed rod 23 and the control rod 25 are offset, driving the control rod 25 and the control plate 24 to rotate counterclockwise, and the transmission rod 29 drives the connecting gear 40 to rotate counterclockwise, and the connecting gear 40 drives the connecting rack 41 to move in the direction away from the pointed plate 21, and the connecting rack 41 drives the first connecting rod 34 or drives the first connecting rod 34 through the right-angle plate 39 to move in the direction away from the pointed plate 21, and the first connecting rod 34 drives the square plate 32 to move in the direction away from the pointed plate 21, and the square plate 32 and the food to be detected are offset, forming a knock on the food to be detected, or causing the food to be detected to move, thereby improving the subsequent detection effect of the food to be detected. When the fixed rod 23 and the control rod 25 are disconnected, under the action of the second spring 43, the square plate 32 returns to the through groove 31 again, and can then be straight When the movable plate 12 drives the fixed rod 23 to move to the lower left, when the fixed rod 23 and the control rod 25 are against each other, the control rod 25 and the control plate 24 will be driven to rotate clockwise, and the transmission rod 29 drives the connecting gear 40 to rotate clockwise, and the connecting gear 40 drives the connecting rack 41 to move in the direction close to the pointed plate 21, and the connecting rack 41 drives the first connecting rod 34 or drives the first connecting rod 34 through the right-angle plate 39 to move in the direction close to the pointed plate 21, which will cause the square plate 32 to penetrate into the through groove 31 until the control rod 25 and the fixed rod 23 are disconnected. At this time, under the action of the second spring 43, the square plate 32 returns to its original position relative to the through groove 31, that is, when the movable plate 12 drives the fixed rod 23 to move to the lower left, the square plate 32 is always located in the through groove 31, and the square plate 32 will not have any effect on the food to be tested.

[0018] like Figure 12 、 Figure 13 , a cleaning assembly is installed on the lower side of the pointed plate 21, and the cleaning assembly includes a fourth connecting plate 55 fixedly installed on the lower side of the pointed plate 21, and the lower side of the fourth connecting plate 55 is fixedly connected to the receiving box 22, and the receiving box 22 is rotatably connected with a cleaning rod 53, and the outer side of the cleaning rod 53 is fixedly connected to a cleaning cylinder 51, and the outer side of the cleaning cylinder 51 is circumferentially fixedly connected to multiple cleaning plates 52, and the through groove 31 is fixedly connected to the second connecting plate 46, and the side wall of the second connecting plate 46 is rotatably connected to the second connecting rod 47, and the second The outer sides of the connecting rod 47 and the transmission rod 29 are fixedly connected to the bevel gear 45, and the two bevel gears 45 are meshed with each other. The lower side of the pointed plate 21 is fixedly connected to the third connecting plate 54. The side wall of the third connecting plate 54 is rotatably connected to the guide rod 49. The guide rod 49 is connected to the second connecting rod 47 through the second pulley assembly 48. The guide rod 49 is connected to the cleaning rod 53 through the third pulley assembly 50. An arc plate 56 is fixedly connected to the receiving box 22, and the surface of the arc plate 56 is smooth. First of all, when food is tested, there will be a certain amount of food residue. When the transmission rod 29 rotates, the transmission rod 29 drives the second connecting rod 47 to rotate through the bevel gear 45, and the second connecting rod 47 drives the guide rod 49 to rotate through the second pulley assembly 48. The guide rod 49 drives the cleaning rod 53 to rotate through the third pulley assembly 50, and the cleaning rod 53 drives the cleaning cylinder 51 and the cleaning plate 52 to rotate, so that the food residue moved to the front side of the receiving box 22 can enter the receiving box 22 along the arc plate 56 under the action of the cleaning plate 52, thereby completing the simple collection effect of the food residue.

[0019] A method for a multi-station detection device for food detection, comprising the following steps: S1. Place the food to be tested on the conveyor belt 5 and start the motor 6 to move the food on the conveyor belt 5 into the housing 1. S2, start the transmitter 8 and the receiver 9 to perform multi-station detection on the food moved into the housing 1; S3. After the detection is completed, unqualified food is selected according to the signal of the receiver 9, and the food detection operation is finally completed.

[0020] In the present invention, when food inspection is required, the food to be inspected is placed on the conveyor belt 5, the motor 6 is started, the motor 6 drives the conveyor rod 3 to rotate, the conveyor rod 3 drives the conveyor roller 4 to rotate, the conveyor roller 4 drives the conveyor belt 5 to move, and the conveyor belt 5 drives the food placed on the upper side thereof to pass through the shell 1, that is, through the working area of the transmitter 8 and the receiver 9. Secondly, a display screen is installed on the outer surface of the shell 1, and the receiver 9 can transmit the measured data to the display screen. After the food passes through the working area of the transmitter 8 and the receiver 9, the receiver 9 transmits the obtained data to the display screen. The staff can make judgments based on the obtained data, and then complete the inspection operation of the food placed on the upper side of the conveyor belt 5, and then pick out the unqualified food, and finally complete the overall food inspection operation. The above are all existing technologies and no unnecessary details are given. Before the above work, first adjust the position of the flattening plate 13 according to the size of the food to be tested, rotate the first threaded rod 17, and under the restriction of the telescopic sleeve 18, the rotating first threaded rod 17 will drive the movable plate 12 to move up and down relative to the shell 1, and the movable plate 12 drives the flattening plate 13 to move up and down until the distance between the flattening plate 13 and the conveyor belt 5 meets the working needs, that is, the distance between the flattening plate 13 and the conveyor belt 5 is between the size diameter of one food to be tested and the size diameter of two foods to be tested. When the food to be tested placed on the upper side of the conveyor belt 5 moves to the outside of the flattening plate 13, under the action of the flattening plate 13, the possibility of multiple foods to be tested piling up can be reduced. At the same time, under the action of the first pulley assembly 10, the rotating rod 7 will be caused to rotate, and the rotating rod 7 drives The reciprocating screw rod 14 rotates. Since the reciprocating screw rod 14 and the reciprocating wire sleeve 11 are threadedly connected, and under the limiting action of the positioning rod 15, when the reciprocating screw rod 14 rotates following the rotating rod 7, the reciprocating wire sleeve 11 will move back and forth along the positioning rod 15. The reciprocating wire sleeve 11 drives the movable plate 12 to move back and forth through the fixed plate 16 and the telescopic sleeve 18, and the movable plate 12 drives the tiling plate 13 to move back and forth. Under the action of the tiling plate 13, it can not only form a limiting effect on the food to be tested, but also reduce the possibility of the food to be tested piling up. Under the action of the tiling plate 13 that moves back and forth, when there is a lot of food to be tested on the outside of the tiling plate 13, under the action of the tiling plate 13 that moves back and forth, the food to be tested can be moved along the tiling plate 13, thereby forming a tiling effect on the food, which provides convenience for subsequent detection operations; The second threaded rod 33 is rotated to move the second threaded rod 33 in the direction away from the first connecting plate 30, and the second threaded rod 33 drives the limiting plate 27 to move until the limiting plate 27 and the positioning plate 26 are disconnected. Then, the first connecting plate 30 is moved along the cross groove 28, and the first connecting plate 30 drives the pointed plate 21 to move until the position of the pointed plate 21 meets the working requirements. The second threaded rod 33 is rotated again, and the second threaded rod 33 drives the limiting plate 27 to move until the limiting plate 27 moves to between the two adjacent positioning plates 26, thereby completing the adjustment and fixing operation of the position of the pointed plate 21. Then, after the food to be inspected passes through the flattening plate 13, under the action of the pointed plate 21, the food to be inspected can be separated, the distance between the food to be inspected can be expanded, and the food to be inspected can be better inspected. Before performing food inspection, the angle between the square plate 32 and the first connecting rod 34 is adjusted according to the actual work needs. When the square plate 32 is needed to knock the food to be inspected, the square plate 32 and the through slot 31 should be in a vertical state (i.e. Figure 11When the square plate 32 is needed to flip the food to be tested or to displace the food to be tested, there should be a certain angle between the square plate 32 and the through slot 31, and when the square plate 32 moves, the outer surface of the square plate 32 can be against the food to be tested, so that the food to be tested can be moved. In the above process, when the square plate 32 needs to be adjusted, the snap ring 37 is first moved away from the square plate 32, so that the snap ring 37 compresses the first spring 38, and the snap ring 37 drives the clamping rod 35 to move until the clamping rod 35 is removed from the clamping slot 36, and then the square plate is rotated around the first connecting rod 34. 32, until the position of the square plate 32 meets the working needs, and then the snap ring 37 is loosened. At this time, under the action of the first spring 38, the clamping rod 35 enters the corresponding clamping groove 36, thereby completing the adjustment and fixing operation of the square plate 32. Then, when performing the food testing operation, when the movable plate 12 and the flattening plate 13 move back and forth, since the slide plate 19 and the inner wall of the shell 1 are abutted and connected to the shell 1 for sliding up and down, the movable plate 12 moving back and forth will drive the fixed rod 23 to move back and forth relative to the slide plate 19. When the fixed rod 23 and the control rod 25 are abutted, the control rod 25 and the control plate 24 will be driven to rotate around the transmission rod 29 as the center, so as to Figure 8 When the movable plate 12 drives the fixed rod 23 to move to the upper right, the fixed rod 23 and the control rod 25 are offset, driving the control rod 25 and the control plate 24 to rotate counterclockwise, and the transmission rod 29 drives the connecting gear 40 to rotate counterclockwise, and the connecting gear 40 drives the connecting rack 41 to move in the direction away from the pointed plate 21, and the connecting rack 41 drives the first connecting rod 34 or drives the first connecting rod 34 to move in the direction away from the pointed plate 21 through the right-angle plate 39, and the first connecting rod 34 drives the square plate 32 to move in the direction away from the pointed plate 21, and the square plate 32 and the food to be detected are offset, forming a knock on the food to be detected, or causing the food to be detected to move, thereby improving the subsequent detection effect of the food to be detected. When the fixed rod 23 and the control rod 25 are disconnected, under the action of the second spring 43, the square plate 32 returns to the through groove 31 again, thereby continuously forming the processing effect of the food to be detected; When the transmission rod 29 rotates, the transmission rod 29 drives the second connecting rod 47 to rotate through the bevel gear 45, the second connecting rod 47 drives the guide rod 49 to rotate through the second pulley assembly 48, and the guide rod 49 drives the cleaning rod 53 to rotate through the third pulley assembly 50. The cleaning rod 53 drives the cleaning cylinder 51 and the cleaning plate 52 to rotate, so that the food residue moved to the front side of the receiving box 22 can enter the receiving box 22 along the arc plate 56 under the action of the cleaning plate 52, thereby completing the simple collection effect of the food residue.
