Technical Field

[0001] The utility model relates to the technical field of food metal detection, in particular to a self-sorting metal detector for food. Background Art

[0002] Food metal detectors include full metal detectors, iron metal detectors, aluminum foil metal detectors, etc. They are mainly used in food industries such as sauces, sausages, ham, soups, pickled foods, fast food, food additives, starch, tobacco, dairy products, etc. They are suitable for product detection with strong product effects and other industries with extremely high requirements for detection sensitivity, anti-interference ability and waterproofness. Full metal detectors are used to detect broken needles, iron wires or lead, copper, aluminum, tin, stainless steel and other metals mixed or lost in food, raw materials or products.

[0003] Since food metal detectors generally do not have a sorting function, a more common method is to let staff pick out unqualified food according to the alarm of the detector. However, the manual sorting method has a low degree of automation and requires a certain amount of manpower. In addition, when detecting larger foods, existing food metal detectors cannot quickly adjust the height of the detector, resulting in low practicality of existing food metal detectors.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] A self-sorting food metal detector, the structure of which is as follows Figure 1-Figure 4 As shown, it includes a first support frame 1, on which a first conveyor belt 2 is installed, a detector 3 is arranged on one side of the top end of the first support frame 1, and the detector 3 is located above the first conveyor belt 2, and a diversion support frame 6 is rotatably installed at the rear of the first support frame 1 through a connecting plate 5, and a diversion conveyor belt 7 is arranged on the diversion support frame 6, and a fixed column 14 is arranged on the side of the diversion support frame 6 away from the first support frame 1, and a second support frame 8 is arranged at one end of the diversion support frame 6 away from the first support frame 1, a second conveyor belt 9 is arranged on the top of the second support frame 8, and a third conveyor belt 10 parallel to the second conveyor belt 9 is arranged in the middle of the second support frame 8, a second motor 11 is arranged on one side of the diversion support frame 6, and a diversion motor 12 is arranged on the other side of the diversion support frame 6, and the power output end of the diversion motor 12 is connected to the fixed column 14 through a connecting rod.

[0028] The food to be tested moves intermittently on the first conveyor belt 2 toward the detector 3. After being tested by the detector 3, the safe food is conveyed to the diverter conveyor belt 7. The diverter conveyor belt 7 is on the same level as the second conveyor belt 9. The safe food is conveyed to the second conveyor belt 9 through the diverter conveyor belt 7. The safe food is conveyed to the next process through the second conveyor belt 9.

[0029] When the detector 3 detects food containing metal residues, the diversion motor 12 on the connecting plate 5 is started, and the diversion motor 12 drives the rotating rod 13 to rotate. Since the end of the rotating rod 13 away from the diversion motor 12 is connected to the diversion support frame 6 through the fixed column 14, and the diversion support frame 6 is connected to the connecting plate 5 through a rotating shaft, the separation conveyor belt follows the rotation of the diversion support frame 6 and is tilted. The end of the diversion conveyor belt 7 away from the first conveyor belt 2 is inclined toward the third conveyor belt 10. If food containing metal residues is detected, it will be conveyed to the third conveyor belt 10 through the inclined diversion conveyor belt 7, and the third conveyor belt 10 will convey the food containing metal residues to the next process. The diversion of food is achieved through the diversion conveyor belt 7 without the intervention of operators, thereby reducing the workload of operators and improving the sorting efficiency.

[0030] Baffles 19 are provided on both sides of the first conveyor belt 2 , the diverter conveyor belt 7 , the second conveyor belt 9 and the third conveyor belt 10 .

[0031] The baffle 19 can ensure that the detected food is better conveyed on the first conveyor belt 2, the diversion conveyor belt 7, the second conveyor belt 9 and the third conveyor belt 10, and prevent the detected food from falling to the outside, thereby improving the practicality of the device.

[0032] The first support frame 1 is provided with a first motor 4 for driving the first conveyor belt 2 on one end side away from the diversion support frame 6. The first motor 4 can drive the food to be sorted to pass through the detector 3 for detection, and then be conveyed to the diversion conveyor belt 7 for sorting.

[0033] The diverter support frame 6 is detachably connected to the first support frame 1 , and the diverter support frame 6 is connected to the connecting plate 5 via a rotating shaft.

[0034] The diverter support frame 6 is connected to the connecting plate 5 via a rotating shaft. Therefore, when the diverter motor 12 on the connecting plate 5 drives the rotating rod 13 to rotate, the end of the diverter support frame 6 away from the first support frame 1 is connected to the free end of the rotating rod 13 via the fixing column 14. Therefore, the rotation of the diverter support frame on the connecting plate 5 can be realized, and the diverter conveyor belt 7 can be tilted, so that the diverter conveyor belt 7 can be tilted toward the third conveyor belt 10 to transport the detected food, thereby realizing the food sorting work;

[0035] Since the diversion support frame 6 is detachably connected to the first support frame 1, it is convenient to disassemble the diversion support frame 6 after the sorting work is completed, and clean and disinfect the diversion conveyor belt 7 to avoid the breeding of bacteria and the like, which may contaminate the food that needs to be sorted later, thereby improving the practicality of the device and ensuring the hygiene of the food after sorting.

[0036] The surfaces of the first conveyor belt 2, the diverter conveyor belt 7, the second conveyor belt 9 and the third conveyor belt 10 are provided with a polyurethane coating.

[0037] After the sorting work of the device is completed, the polyurethane coating has waterproof, antibacterial and wear-resistant properties, which makes it easy to rinse, disinfect and sterilize the device, thereby avoiding food contamination during subsequent food sorting. At the same time, it ensures the service life of all conveyor belts of the device and ensures the orderly progress of the sorting work.

[0038] The second conveyor belt 9 and the third conveyor belt 10 are both provided with a power source for driving the rotation thereof.

[0039] By driving the power source, the food conveyed to the second conveyor belt 9 and the third conveyor belt 10 can be conveyed to the subsequent process, thereby improving the smoothness of the sorting work. At the same time, there is no need for operators to carry the sorted food, thereby reducing the labor intensity of operators.

[0040] Embodiment 2

[0041] On the basis of the first embodiment, a column 18 is provided on one side of the upper end of the first support frame 1, and a plurality of limit grooves 15 are evenly provided on the column 18 from top to bottom. A through hole adapted to the limit groove 15 is provided on one side of the detector 3, and a limit block 16 is installed in the through hole. The detector 3 is connected to the column 18 via the limit block 16, and a pull ring 17 is provided at the end of the limit block 16.

[0042] When the food to be sorted by the device is large in size, the detector 3 can be unlocked by the limit block 16, so that the operator can adjust the height of the detector 3 from the first conveyor belt 2 according to the height of the food to be sorted. The detector 3 is locked on the limit groove 15 of the column 18 by the limit block 16, and the pull ring 17 can facilitate the operator to quickly extract and insert the limit block 16 from the limit groove 15, thereby improving the efficiency of height adjustment of the detector 3, indirectly improving the sorting efficiency, and improving the practicability of the detector 3 of the device.
