Gold detector and conveyor belt power linkage device

Abstract

This utility model relates to the field of food processing, and particularly to a linkage device between a metal detector and a conveyor belt power supply. It includes a first mounting frame, a second mounting frame, a pressure sensor, and a rotating column. A first conveyor belt is mounted on the upper end of the first mounting frame, and a second conveyor belt is mounted on the upper end of the second mounting frame. A pressure sensor is mounted on the lower end of the second mounting frame, and a rotating column is rotatably mounted on the lower end of the second mounting frame. Infrared emitters arranged in a circular array are fixed to the outer wall of the rotating column, and an infrared receiver is fixed to the lower surface of the second mounting frame. The infrared emitters and receivers are compatible. This device utilizes weight and frequency detection to achieve a linkage effect between the operation of the metal detector and the switching on / off of the conveyor belt. It solves the problem of existing metal detectors lacking a linkage design with the conveyor belt power supply, which causes the conveyor belt to continue conveying materials even when the metal detector suddenly stops, leading to errors in the overall operation.

Description

Technical Field

[0001] This utility model relates to the field of food processing, and in particular to a metal detector and a power supply linkage device for a conveyor belt. Background Technology

[0002] Metal detectors primarily utilize the principle of electromagnetic induction. When a product passes through the detector's head, if it contains metal, the metal will interfere with the magnetic field generated by the detector. This change in magnetic field is detected by the induction coil inside the detector, generating a signal. This signal, after amplification and processing, can trigger an alarm or cause the equipment to automatically reject products containing metal impurities. For example, when a biscuit containing metal particles passes through the detector's area, the magnetic field of the detector head will change due to the metal particles, which will then be detected by the induction coil.

[0003] While existing technologies can achieve certain performance results for metal detectors, they suffer from a drawback: the lack of linkage between the metal detector and the conveyor belt power supply results in the conveyor belt continuing to transport materials even when the metal detector suddenly stops, causing overall operational errors. In view of this, we propose a linkage device between the metal detector and the conveyor belt power supply, which solves the above-mentioned problem. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a power linkage device for a metal detector and a conveyor belt.

[0005] The technical solution of this utility model is a metal detector and conveyor belt power supply linkage device. The metal detector mainly utilizes the principle of electromagnetic induction. When a product passes through the detection head of the metal detector, if the product contains metal, the metal will interfere with the magnetic field generated by the detection head. This change in magnetic field is detected by the induction coil inside the metal detector, and then a signal is generated. After amplification and processing, this signal can trigger an alarm device or cause the equipment to automatically reject products containing metal impurities. For example, when a biscuit containing metal particles passes through the detection area of ​​the metal detector, the magnetic field of the detection head will change due to the metal particles, and then the signal will be captured by the induction coil.

[0006] Preferably, a bracket is fixed to one lower end of the mounting frame, and a base is fixed to one lower end of the bracket.

[0007] Preferably, a bracket two is fixed to the upper end of the pressure sensor, the upper end of the bracket two is fixedly connected to the lower end of the mounting bracket two, and a base two is fixed to the lower end of the pressure sensor.

[0008] Preferably, a fixed frame is fixed to the lower end of the mounting bracket two, the rotating column is rotatably mounted between the fixed frames, a motor three is fixed to the outer wall of one side of the fixed frame, and the output shaft of the motor three is fixedly connected to the rotation center of one side of the rotating column.

[0009] Preferably, a controller is fixed to one side outer wall of the mounting bracket, a connecting bracket is fixed to the middle of the lower end of the mounting bracket, and a receiving plate is fixed to the upper end of the connecting bracket.

[0010] Preferably, a motor is fixed to one outer wall of the mounting bracket, and the output shaft of the motor is fixedly connected to the rotation center of one side of the conveyor belt.

[0011] Preferably, a second motor is fixed to one side of the outer wall of the second mounting bracket, and the output shaft of the second motor is fixedly connected to the rotation center of one side of the second conveyor belt.

[0012] Preferably, a telescopic cylinder is fixed to one outer wall of the mounting frame, a telescopic rod is inserted into the telescopic cylinder, and the other side of the telescopic rod is fixedly connected to one side of the mounting frame.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] I. This utility model can utilize the designed conveyor belt II with weight detection function as a detection module for material conveying. When the metal detector stops, the material will accumulate on the conveyor belt II, and the pressure sensor will sense the weight change and then work with the controller to immediately shut down the operation of motor I and motor II.

[0015] II. Based on the first beneficial effect, in order to ensure the timely cessation of the operation of motor 1 and motor 2, this device can utilize the infrared transmitter and receiver with timed signal transmission and reception, driven by motor 3 which shares power with the downstream metal detector. When a shutdown occurs, the signal transmission will be interrupted, and this signal will be used in conjunction with the controller to shut down motor 1 and motor 2.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1-5 As shown, this embodiment is a metal detector and conveyor belt power linkage device, including mounting frame 1, mounting frame 2 13, pressure sensor 10 and rotating column 19. The upper end of mounting frame 1 is provided with conveyor belt 15, the upper end of mounting frame 2 13 is provided with conveyor belt 2 12, the lower end of mounting frame 2 13 is provided with pressure sensor 10, and the lower end of mounting frame 2 13 is rotatably mounted with rotating column 19. The outer wall of rotating column 19 is fixed with infrared emitters 20 distributed in a ring array, and the lower surface of mounting frame 2 13 is fixed with infrared receiver 21. The infrared emitters 20 and infrared receiver 21 are adapted to each other.

[0030] In operation, this device uses motor 2 to drive conveyor belt 15 to transport materials. The materials pass through receiving plate 17 and then enter conveyor belt 12. After being transported by conveyor belt 12, the materials enter the processing area at the rear. A pressure sensor 10 is installed at the lower end of conveyor belt 12 to sense the weight of the materials on top of conveyor belt 12 in real time. If the machine at the rear stops, the materials will accumulate on top of conveyor belt 12. Then, the pressure sensor 10 will detect that the weight exceeds the limit and send a signal to controller 5. Controller 5 will then send a stop signal to motors 2 and 14. Additionally, a stop signal is set on mounting frame 2... The rotating column 19 at the lower end of 13 can rotate continuously under the drive of motor 3 9. Motor 3 9 and the rear processing device share a power supply. When the rear machine stops, motor 3 9 will stop, and the rotating column 19 will stop rotating. In the original design, the infrared transmitter 20 would send a signal to the infrared receiver 21 at regular intervals due to the rotation effect. When it stops, this signal will be interrupted. When the signal is interrupted, the controller 5 will also command motor 1 2 and motor 2 14 to stop. This device can realize the linkage effect between the conveyor belt and the power supply, ensuring that the conveyor belt will not continue to transport materials after the machine stops.

[0031] Example 2

[0032] Please see Figures 1-5 As shown, this embodiment, based on embodiment 1, further includes: a bracket 3 fixed to the lower end of the mounting frame 1, and a base 4 fixed to the lower end of the bracket 3. The bracket 3 and the base 4 can increase the stability of the device and reduce the propagation of noise to a certain extent.

[0033] The upper end of the pressure sensor 10 is fixed with a bracket 2 11, the upper end of the bracket 2 11 is fixedly connected to the lower end of the mounting frame 2 13, and the lower end of the pressure sensor 10 is fixed with a base 2 8. The bracket 2 11 and the base 2 8 can increase the stability of the device and reduce the transmission of noise to a certain extent. The pressure sensor 10 can sense the total weight of the mounting frame 2 13. When it is too heavy, it means that the material is accumulating on the upper end of the mounting frame 2 13 and has not entered the metal detector.

[0034] Mounting bracket 2 13 has a fixed bracket 18 at its lower end. The rotating column 19 is rotatably mounted between the fixed brackets 18. A motor 3 9 is fixed on the outer wall of one side of the fixed bracket 18. The output shaft of motor 3 9 is fixedly connected to the rotation center of one side of the rotating column 19. Motor 3 9 can drive the rotating column 19 to rotate at a constant speed. When rotating, the infrared transmitter 20 will continuously transmit signals to the infrared receiver 21. The infrared receiver 21 will receive signals at a certain frequency. If the signal reception time is too long, it means that the common power circuit of motor 3 9 and the metal detector is broken and needs to be maintained. Then, immediately cooperate with controller 5 to shut down motor 1 2 and motor 2 14 to prevent continued feeding.

[0035] A controller 5 is fixed to one side of the outer wall of the mounting frame 1. A connecting frame 16 is fixed to the middle of the lower end of the mounting frame 1. A receiving plate 17 is fixed to the upper end of the connecting frame 16. The receiving plate 17 can effectively connect the surface connection parts of the conveyor belt 15 and the conveyor belt 2 12 to prevent material from leaking.

[0036] Motor 2 is fixed to one side of the outer wall of mounting frame 1. The output shaft of motor 2 is fixedly connected to the rotation center of one side of conveyor belt 15. Motor 2 can drive conveyor belt 15 to rotate, so as to achieve the material conveying effect.

[0037] Motor 2 14 is fixed to one side of the outer wall of mounting frame 2 13. The output shaft of motor 2 14 is fixedly connected to the rotation center of one side of conveyor belt 2 12. Motor 2 14 can drive conveyor belt 2 12 to rotate, so as to achieve the material conveying effect.

[0038] A telescopic cylinder 6 is fixed to one side of the outer wall of the mounting frame 1. A telescopic rod 7 is inserted into the telescopic cylinder 6. The other side of the telescopic rod 7 is fixedly connected to one side of the mounting frame 2 13. The design of the telescopic cylinder 6 and the telescopic rod 7 can realize the adjustment effect of the distance between the mounting frame 2 13 and the mounting frame 1. The adjustment amount is small and will not affect the bridging effect of the receiving plate 17 on the material.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
