All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 8, the invention provides a portable intelligent food heavy metal detection system, which comprises a conveyor belt 1, a circulation support 2 connected end to end, and a plurality of circulation type detectors 3 mounted on the circulation support 2, wherein the circulation support 2 has a lower horizontal section which is just opposite to and parallel to the conveyor belt 1, the plurality of circulation type detectors 3 are arranged on the circulation support 2 at equal intervals, and the plurality of circulation type detectors 3 move synchronously along with a plurality of food to be detected on the conveyor belt 1 at the lower horizontal section of the circulation support 2 and detect the food to be detected until the circulation type detectors 3 finish detection and leave the lower horizontal section of the circulation support 2.
A plurality of circulating detectors 3 carry out cyclic motion at the uniform velocity along circulating support 2, and the interval of adjacent circulating detector 3 is debugged according to the interval of the adjacent food that awaits measuring on conveyer belt 1 and is matchd to the messenger lies in a plurality of circulating detectors 3 and moves back to the horizontal segment, on conveyer belt 1 with a plurality of circulating detectors 3 one-to-one on the horizontal segment down a plurality of food that await measuring homoenergetic are in the detection region under corresponding circulating detector 3 simultaneously.
Before the plurality of circulating detectors 3 start circulating movement, the detection area of any one circulating detector 3 on the lower horizontal section is detected, and when the detection area of the circulating detector 3 on the lower horizontal section is detected to have food to be detected entering, the plurality of circulating detectors 3 immediately move at the same speed as the conveying belt 1, so that the circulating detectors 3 are matched with the food to be detected on the conveying belt 1 in position. And the food to be detected is detected by the lower horizontal section upper circulating type detector 3 in the process of synchronously moving along with the food to be detected in the detection area of the lower horizontal section upper circulating type detector 3 until the detection is finished, the circulating type detector 3 moves from the ascending section at the tail end of the circulating bracket 2 to the upper horizontal section right above the lower horizontal section so as to enable the circulating type detector 3 to be separated from the following of the food to be detected after the detection is finished, and the circulating type detector 3 on the upper horizontal section moves to the lower horizontal section again through the descending section at the front end of the circulating bracket 2 and detects new food to be detected on the conveying belt 1 again. The food to be detected on the conveying belt 1 is continuously detected and synchronously detected by the plurality of circulating detectors 3 in a circulating motion mode.
According to the invention, the food to be detected which is equidistantly arranged on the conveying belt 1 is detected by the driving circulating detectors 3 which are equidistantly arranged in a mode of combining the following detection and the circulating detection, so that sufficient time is provided for the circulating detectors 3 to detect the food to be detected, the intelligent food detection device can meet the requirements of more detection items with different requirements on the detection time, the applicability of the intelligent food detection device is improved, the requirement on the rapid detection capability of the circulating detectors 3 is reduced, and the accuracy of the detection result of the circulating detectors 3 is favorably improved due to the fact that more time is provided for carrying out data acquisition and analysis on the food to be detected.
Wherein, circulation support 2 includes circulation guide rail 201 and installs drive belt 202 on circulation guide rail 201, and circulation guide rail 201 and drive belt 202 all are provided with a pair ofly, and the inboard that a pair of circulation guide rail 201 is close to each other all sets up the embedded groove 2011 that supplies drive belt 202 installation and activity, connects through slabby roof beam 203 between a pair of drive belt 202, and circulating detector 3 installs on slabby roof beam 203. The pair of circulation guide rails 201 are parallel to each other and are fixedly connected through the connecting beam 204, the connecting beam 204 is provided with a plurality of circulation driving mechanisms 4 connected with the transmission belts 202, openings communicated with the embedded grooves 2011 are formed in the circulation guide rails 201, and the connecting portions of the circulation driving mechanisms 4 penetrate through the openings to be connected with the transmission belts 202.
The pair of circulation guide rails 201 are connected and fixed by the connection beams 204 to maintain a state of being parallel to each other, and the pair of circulation guide rails 201 are fixedly installed by being supported on both side frames of the conveyor belt 1 or on both side floors by supports. The circulating drive mechanism 4 circulates the plurality of circulating detectors 3 mounted on the conveyor belts 202 on both sides by the plate-like beams 203 at a constant speed by driving the conveyor belts 202 at a constant speed so that the circulating detectors 3 match the holding positions of the food to be measured on the conveyor belt 1 moving at a constant speed at the same speed. The plurality of circulation driving mechanisms 4 are mutually standby and mutually assist, that is, when a certain circulation driving mechanism 4 is stopped due to a fault, the transmission belt 202 is driven by the rest circulation driving mechanisms 4, so as to avoid the situation that the circulation detector 3 cannot normally detect the food to be detected passing below due to the stop of the transmission belt 202. When a slip occurs between the connection portion of one of the circulation driving mechanisms 4 and the transmission belt 202, the other circulation driving mechanisms 4 provide a continuous and stable power input to the transmission belt 202, thereby preventing the transmission belt 202 and the circulation detectors 3 from breaking the uniform motion state and affecting the position matching of the circulation detectors 3 and the food to be measured.
It should be noted that the driving belt 202 is a flexible belt body made of rubber or the like with two closed ends, so as to meet the requirement of moving in the insertion groove 2011 with a bending section. In addition, in order to reduce the frictional force between the transmission belt 202 and the groove wall of the fitting groove 2011, a rotating roller is usually fitted in the groove wall of the fitting groove 2011 to support the transmission belt 202 with the rotating roller and to avoid direct contact of the transmission belt 202 with the groove wall of the fitting groove 2011, thereby reducing the frictional force of the movement of the transmission belt 202. Moreover, in order to reduce the influence of the deformation of the transmission belt 202 on the position matching stability of the circulating detector 3 and the food to be detected on the transmission belt 1, the transmission belt 202 is embedded with flexible ribs made of materials with small stretching amount and thermal expansion amount to reduce the deformation of the transmission belt 202 caused by temperature change and stretching, thereby being beneficial to prolonging the service life of the transmission belt 202 and improving the position matching stability of the circulating detector 3 on the transmission belt 202 and the food to be detected on the transmission belt 1.
In a further preferred embodiment, the drive belt 202 is provided with a plurality of teeth 5 arranged on its front side facing the gap, and the endless drive means 4 is in meshing engagement with the teeth 5 of the drive belt 202 via a toothed wheel 6 passing through the gap.

The circulation driving mechanism 4 and the transmission belt 202 are transmitted through the meshing teeth 5 and the gear 6 which are meshed with each other, so that the transmission belt 202 and the connection part of the circulation driving mechanism 4 are prevented from slipping, and the stability of matching the circulation type detector 3 and the position of the food to be detected on the conveying belt 1 is improved.
