Description

Technical Field

[0001] The present invention belongs to the technical field of food testing equipment, and in particular relates to an automated testing device and a testing method for food quality and safety. Background Art

[0002] As people's quality of life continues to improve, their awareness of food safety is also growing. In recent years, the frequent exposure of food safety issues in the media has reminded food production companies that they must strengthen testing and management during the food production process. Against this backdrop, process management and testing for food processing production lines have emerged, and food metal detection equipment is one of the detection equipment that has emerged to meet this need.

[0003] Food metal detectors use high-speed digital signal processing devices and intelligent algorithms to detect metals in foods such as frozen foods, meat, rice, sausage, and preserved foods. The food to be tested is placed on a conveyor belt and passed through a detection point. A transmitting coil at a specific frequency and amplitude emits an electromagnetic field toward the food. If the finished food contains tiny metal particles, this electromagnetic field is disrupted, creating a magnetic field disparity in the receiving coil on the other side of the food. This disparity transmits a signal to the controller, triggering an alarm. The controller utilizes high-speed digital signal processing devices and intelligent algorithms, resulting in high detection accuracy and stability.

[0004] Existing food packaging with a lot of oil on its surface can adhere to the conveyor belt. If metal particles adhere to the surface of the food packaging, when placed on the conveyor belt, the metal particles may in turn adhere to the conveyor belt and pass through the detection position multiple times, affecting the detection accuracy of the metal detection equipment. To this end, we provide an automated food quality and safety testing device and detection method to solve the above problems. Summary of the Invention

[0041] The outer wall of the lifting rod 210 is fixedly connected to a first cross bar 219, and the end of the first cross bar 219 is fixedly connected to an arc-shaped iron plate 220 that is slidably connected to the inner wall of the cylindrical tube 207.

Guide rods 230 are symmetrically fixedly connected between the purification box 201 and the cleaning box 206. A rectangular frame 231 sleeved on the outer wall of the connecting column 229 is slidably connected between the two guide rods 230.

[0042] The operation process of this embodiment is as follows: during the intermittent clockwise rotation of the conveyor belt 115, the conveyor belt 115 will be intermittently immersed in the cleaning liquid in the cleaning box 206, and the second motor 227 is controlled to drive the turntable 228 to rotate, so that the turntable 228 drives the connecting column 229 to make a circular motion, so that the connecting column 229 further drives the rectangular frame 231 to move back and forth in the vertical direction, thereby driving the arc-shaped electromagnet 233 to move up and down reciprocatingly through the two L-shaped fixing rods 232 (before the second motor 227 works, the arc-shaped electromagnet 233 is energized so that the arc-shaped electromagnet 233 adsorbs the column arc-shaped iron plate 220, so that the arc-shaped iron plate 220 and the arc-shaped electromagnet 233 move synchronously), thereby driving the arc-shaped iron plate 220 to move up and down reciprocatingly, and then driving the lifting rod 210 to move up and down reciprocatingly through the first cross bar 219;

[0043] During the upward movement of the lifting rod 210, the lifting rod 210 drives the mounting plate 211 to move upward, thereby driving the two rotating plates 212 to rotate in the direction of moving away from each other, and the two brush plates 213 are driven to move in the direction of moving away from each other through the blocking plate 215 and the extension rod 214. During the downward movement of the lifting rod 210, the mounting plate 211 is driven downward, thereby driving the two rotating plates 212 to rotate in the direction of approaching each other, further driving the two brush plates 213 to move in the direction of approaching each other, and the two brush plates 213 are moved back and forth in the direction of moving closer to or away from each other, so that the brush plates 213 can brush the surface of the conveyor belt 115, thereby improving the cleanliness of the surface of the conveyor belt 115 and avoiding oil stains and metal residues adhering to the surface of the conveyor belt 115, which may affect the accuracy of the subsequent food detection;

[0044] By moving the lifting rod 210 downward, the lifting rod 210 drives the second annular plate 224 downward, and the cleaning liquid below the sealing plate 226 will push open the sealing plate 226, allowing more cleaning liquid to enter the top of the sealing plate 226. At the same time, the two blocking plates 215 move toward each other, so that one of the blocking plates blocks the drainage hole 217 in the cleaning box 206. At this time, the cleaning liquid in the cleaning box 206 stops flowing into the purification box 201). When the lifting rod 210 moves upward, the lifting rod 210 drives the second annular plate 224 upward. Under the pressure of the cleaning liquid above the sealing plate 226, the sealing plate 226 moves toward the positioning groove 225, so that the sealing plate 2 26 completes the blocking of the positioning groove 225, thereby pumping the cleaning liquid located above the sealing plate 226 into the cleaning box 206 (at the same time, the two blocking plates 215 move away from each other, so that one of the blocking plates 215 is dislocated from the drainage hole 217. At this time, the cleaning liquid in the cleaning box 206 will flow into the purification chamber 203 in the purification box 201 through the conduit 218. Through the use of the semipermeable membrane 202, the liquid in the purification chamber 203 enters the liquid storage chamber 204 through the semipermeable membrane 202, thereby completing the purification and recycling of the cleaning liquid, effectively ensuring the cleanliness of the cleaning liquid, and preventing the metal residues mixed in the cleaning liquid from being contaminated on the conveyor belt 115 again, causing secondary pollution.

[0045] For example three, please refer to Figure 1-11, the present embodiment 3 is improved as follows on the basis of the embodiment 1, the wiping assembly 3 includes a support rod 301 fixedly connected to the top of the base 101, the top of the support rod 301 is fixedly connected to a U-shaped support plate 302, both ends of the U-shaped support plate 302 are fixedly connected to vertical plates 303, a third guide roller 304 is symmetrically connected to the two vertical plates 303 for rotation, a receiving roller 305 and a winding roller 306 are rotatably connected between the two vertical plates 303, a release roller 307 is installed on the outer wall of the receiving roller 305, and the release roller 307, A cleaning cloth 308 is wound between the two third guide rollers 304 and the winding roller 306. The end of the output shaft of the winding roller 306 is fixedly connected to the second sprocket 309. A chain is meshed and connected between the second sprocket 309 and the first sprocket 107. A ratchet 310 is fixedly connected to the outer wall of the output shaft of the winding roller 306. A pawl 311 adapted to the ratchet 310 is installed on one side of one vertical plate 303 (the ratchet 310 and the pawl 311 are used in combination to prevent the cleaning cloth 308 from rotating and affecting the cleaning effect).

[0046] The operating process of this embodiment is: the first sprocket 107 rotates counterclockwise intermittently, so that the first sprocket 107 drives the second sprocket 309 to rotate counterclockwise intermittently through the chain, so that the second sprocket 309 further drives the winding roller 306 to rotate intermittently, so that the cleaning cloth 308 is intermittently wound on the winding roller 306. Through the intermittent movement of the cleaning cloth 308, the cleaning cloth 308 is always ensured to be in contact with the cleaned conveyor belt 115 surface with a dry and clean cloth surface, thereby completing the wiping and absorption of the cleaning liquid adhering to the conveyor belt 115 surface, thereby improving the cleanliness and dryness of the conveyor belt 115.
