Description

Technical Field

[0001] The present invention relates to the technical field of food detection, in particular to a food safety detection system. Background Art

[0002] Food safety testing is the process of detecting harmful substances in food according to national standards, primarily focusing on harmful and toxic indicators such as heavy metals and aflatoxins. A key aspect of food science and engineering is the introduction and application of chemical unit operations, which have been developed into food engineering unit operations, thereby promoting the development of the food industry towards large-scale, continuous, and automated production.

[0003] In the actual testing process, for some beverages, powder and water are usually mixed and dissolved in a certain proportion during production. However, the powder is often not completely dissolved and settles at the bottom of the beverage.

[0004] The traditional testing process often involves shaking the beverage and then taking samples for testing. However, this method is difficult to detect after the beverage has settled. Incompletely dissolved powder accumulates at the bottom of the bottle, making it difficult to detect the beverage near the bottom of the bottle and whether it will cause harm to the human body.

DETAILED DESCRIPTION

[0039] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] Example 1

[0041] See also Figures 1-4 The present invention provides a technical solution: a food safety detection system includes a workbench 1, and a barrel 2 for holding beverages located on the upper surface of the workbench 1, a sampling tube 3 for sampling and a driving mechanism 4 for driving the sampling tube 3 to move upward intermittently are arranged above the workbench 1, and a detector 8 for detecting food is arranged above the workbench 1.

[0042] During use, in the initial state, the sampling tube 3 is located inside the barrel 2 and at the bottom of the barrel 2. By providing a driving mechanism 4, the sampling tube 3 is driven to move upward intermittently, so that the sampling tube 3 can sample beverages at different depths in the barrel 2, effectively improving the comprehensiveness of the device during detection.

[0043] The driving mechanism 4 includes a mounting plate 41 and a slide rail 42 vertically fixed to the upper surface of the workbench 1, a T-shaped slide bar 43 being slidably connected to the slide rail 42, a rack 44 being fixedly connected to the free end of the T-shaped slide bar 43, a non-complete gear 45 driven by an external driving device being rotatably connected to the surface of the mounting plate 41, the non-complete gear 45 being intermittently meshed with the rack 44, and the sampling tube 3 being fixedly mounted on the lower end of the rack 44.

[0044] The external driving device is a motor.

[0045] The driving mechanism 4 also includes a U-shaped frame 461 fixedly connected to the upper surface of the mounting plate 41, the free end of the U-shaped frame 461 is fixedly connected to a cross bar 462, both ends of the cross bar 462 are rotatably connected to a V-shaped rod 463, a rectangular block 464 is fixedly connected to the surface of the V-shaped rod 463, a spring 465 is fixedly connected between the two rectangular blocks 464, the free end of the V-shaped rod 463 is fixedly connected to a hook 466, the hook 466 is stuck in the tooth groove of the rack 44, and the hook 466 is inclined from top to bottom from the side close to the rack 44 to the side away from the rack 44.

[0046] During use, since the hook 466 is stuck in the tooth groove of the rack 44, the rack 44 will not fall downward due to gravity;

[0047] The motor of the external driving device is started to rotate the incomplete gear 45, which drives the rack 44 to intermittently move upward. The rack 44 drives the sampling tube 3 fixed at its lower end to intermittently move upward, so that the sampling tube 3 can take beverage samples at different depths.

[0048] When the rack 44 moves upward, it pushes the two hooks 466 to move in opposite directions, and at the same time, the two V-shaped rods 463 rotate in opposite directions, causing the springs 465 to be stretched. When the rack 44 stops moving upward, the springs 465 pull the two V-shaped rods 463 in opposite directions through the rebound force, and the V-shaped rods 463 can drive the hooks 466 to re-engage the tooth grooves of the rack 44, preventing the rack 44 from falling.

[0049] If the rack 44 and the sampling tube 3 need to be moved downward to return to their original positions, it is necessary to manually pull the two V-shaped rods 463 in opposite directions while the incomplete gear 45 is disengaged from the rack 44, so that the two hooks 466 are disengaged from the tooth grooves of the rack 44. The rack 44 and the driving mechanism 4 can then fall downward under the action of gravity and return to their original positions.

[0070] Example 5

[0071] Please refer to 8. This embodiment further illustrates Example 3. A detection process of the food safety detection system according to claim 9 is characterized in that it includes the following steps:

[0072] S1. Layering

[0073] In the initial state, the sampling tube 3 is located in the barrel 2 and at the bottom of the barrel 2. The sampling tube 3 is driven to move upward intermittently, so that the sampling tube 3 can sample beverages at different depths in the barrel 2;

[0074] S2. Sampling

[0075] The beverage sample is taken out after the sampling tube 3 moves upward, so that the sampling tube 3 can take out beverage samples at different depths;

[0076] S3, transportation

[0077] A plurality of cups 6 are continuously conveyed to the bottom of the vertical tube 564 so that the cups 6 can be loaded with beverage samples dropped from the vertical tube 564 .

[0078] S4. Detection

[0079] When the conveyor belt 74 stops conveying, the detector 8 is driven to move downward, so that the probe of the detector 8 extends into the cup 6 to perform a detection operation on the beverage sample in the cup 6 .

[0080] Working principle: When the food safety detection system is in use, since the hook 466 is stuck in the tooth groove of the rack 44, the rack 44 will not fall downward due to gravity;

[0081] The motor of the external driving device is started to rotate the incomplete gear 45, which drives the rack 44 to intermittently move upward. The rack 44 drives the sampling tube 3 fixed at its lower end to intermittently move upward, so that the sampling tube 3 can take beverage samples at different depths.

[0082] When the rack 44 moves upward, it pushes the two hooks 466 to move in opposite directions, and at the same time, the two V-shaped rods 463 rotate in opposite directions, causing the springs 465 to be stretched. When the rack 44 stops moving upward, the springs 465 pull the two V-shaped rods 463 in opposite directions through the rebound force, and the V-shaped rods 463 can drive the hooks 466 to re-engage the tooth grooves of the rack 44, preventing the rack 44 from falling.

[0083] If the rack 44 and the sampling tube 3 need to be moved downward to return to their original positions, it is necessary to manually pull the two V-shaped rods 463 in opposite directions while the incomplete gear 45 is disengaged from the rack 44, so that the two hooks 466 are disengaged from the tooth grooves of the rack 44. The rack 44 and the driving mechanism 4 can then fall downward to return to their original positions due to gravity.

[0084] When the incomplete gear 45 rotates, it can drive the complete gear 1 51 to rotate intermittently. The complete gear 1 51 can drive the cylindrical cam 52 fixed coaxially with it to rotate intermittently. Each time the cylindrical cam 52 rotates one circle, the movable block 53 can move back and forth in the horizontal direction.

[0085] The movable block 53 can drive the piston rod 568 fixed on its surface to move back and forth in the horizontal direction, and the piston rod 568 can drive the piston plate 569 fixed at one end thereof to move back and forth in the horizontal direction;

[0086] When the piston plate 569 moves toward the outside of the circular tube 562, the beverage in the barrel 2 can be sucked into the circular tube 562 through the horizontal tube 563, the hose 567, and the sampling tube 3. When the piston plate 569 moves toward the inside of the circular tube 562, the beverage in the circular tube 562 can be pushed out through the second one-way valve 566.

[0087] Each time the rack 44 moves upward, it drives the meshing perfect gear 2 76 to rotate once, and the perfect gear 2 76 drives the driven shaft 75 to rotate accordingly. The driven shaft 75 drives the rotating shaft 72 to rotate accordingly through the belt 77, and the rotating shaft 72 drives the conveying roller 73 to rotate accordingly, so that the conveyor belt 74 conveys the cup 6 placed on its surface to the lower end of the vertical tube 564.

[0088] The movable block 53 can drive the L-shaped rod body 93 fixed on its lower surface to move back and forth in the horizontal direction, and the L-shaped rod body 93 can drive the inclined push block 94 fixed at one end thereof to move back and forth in the horizontal direction. When the inclined push block 94 moves toward the side close to the movable block 53, the inclined surface of the inclined push block 94 can push the connecting plate 92 to move downward, and the connecting plate 92 can drive the detector 8 to move downward, so that the probe of the detector 8 is extended into the cup 6 for detection.

[0089] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
