It can transport materials to be tested through a conveying mechanism, detect and classify materials through a metal detector, and put materials into different receiving boxes according to their types through a sorting mechanism.

This method is time-consuming and labor-intensive. Therefore, a PLC-based metal separator is proposed to address the above problems. Utility Model Content

[0024] Please see Figure 1-6 This utility model provides a technical solution:
[0025] A PLC-based metal separator includes a separator base 1, a metal detector 2, a conveying mechanism 3, a dispensing mechanism 4, a housing positioning assembly 5, a material guiding assembly 6, a receiving box assembly 7, and a load detection assembly 8. The housing positioning assembly 5 is located on the upper side of the separator base 1. The housing positioning assembly 5 includes a positioning seat 51 located on the upper side of the separator base 1.

A compression spring 53 is connected, with its lower end fixedly connected to the separator base 1. Multiple limiting shells 54 are fixedly connected to the upper side of the positioning seat 51. Multiple pairs of hydraulic cylinders 55 are fixedly connected to the upper side of the positioning seat 51, with locking blocks 56 fixedly connected to the piston rod ends of each hydraulic cylinder 55.

The front end of each pair of force springs 86 is fixedly connected to the sliding shell 83.
[0026] A metal detector 2 is installed on the upper side of the separator base 1. A conveying mechanism 3, located on the upper side of the separator base 1, is installed below the metal detector 2. A material distribution mechanism 4, located on the upper side of the separator base 1, is installed behind the conveying mechanism 3. The material is detected by the metal detector 2 and transported from left to right by the conveyor mechanism 3. When the material moves to the rear of its corresponding receiving box body 71, the external controller can automatically start the distributing mechanism 4, which pushes the material forward so that it falls from the receiving hopper 62 on the upper side of the support plate 61 into the designated receiving box body 71, thus completing the detection, classification, and collection of the material. Each pair of hydraulic cylinders 55 is located on the left and right sides of the limiting shell 54, and each pair of hydraulic cylinders 55 is symmetrically distributed. The locking blocks 56 are aligned with the side grooves of the limiting shell 54. The movable locking blocks 56, in conjunction with the locking plate 72, lock the receiving box body 71 inside the limiting shell 54. There is a certain gap between the upper side of the support plate 61 and the lower side of the conveyor mechanism 3. The upper side of the receiving hopper 62 is lower than the upper side of the conveyor mechanism 3. When mechanism 4 pushes the material forward, the material can accurately fall into the receiving hopper 62; the width of the receiving box body 71 in the left and right directions is the same as the inner width of the limiting shell 54. The upper end of the front side wall of the receiving box body 71 is in contact with the front end of the support plate 61, and the upper ends of the left and right side walls of the receiving box body 71 are in contact with the lower side of the support plate 61. The left and right sides of the locking plate 72 are provided with grooves that match the locking block 56. After the locking block 56 is inserted into the locking plate 72, the locking plate 72 cannot move; the upper side of the sliding block 82 and the upper side of the sliding shell 83 are in contact with the lower side of the support plate 61. The sliding shell 83 is a "U"-shaped shell structure with an opening on the rear side. The sliding shell 83 is located inside the receiving box body 71. The left and right ends of the sliding shell 83 are in contact with the inner side wall of the receiving box body 71. When the sliding shell 83 moves forward, the material will not enter the sliding shell 83.
[0027] Workflow: Before use, install the separator base 1 in a suitable position and connect the power supply. This device is equipped with an external controller, which is electrically connected to the metal detector 2, conveying mechanism 3, dispensing mechanism 4, vibrating motor 52, multi-stage electric telescopic rod 81, and pressure sensor 84. Manual operation of the external controller allows adjustment of the operating status of the metal detector 2, conveying mechanism 3, dispensing mechanism 4, vibrating motor 52, multi-stage electric telescopic rod 81, and pressure sensor 84. The external controller can be installed in a control room located far from the device. All of the above is existing technology. This device needs to be used in conjunction with a feeding device. When using this device, the operator first feeds the material to be detected into the metal detector 2 using the feeding device. The external controller activates the metal detector 2 and conveyor mechanism 3. The metal detector 2 detects the material, and the conveyor mechanism 3 transports the material from left to right. When the material moves to the rear of its corresponding receiving box body 71, the external controller automatically activates the sorting mechanism 4, which pushes the material forward, causing it to fall from the receiving hopper 62 on the upper side of the support plate 61 into the designated receiving box body 71. This completes the detection, sorting, and receiving of the material. At this time, the locking block 56 is inserted into the locking plate 72 on the lower side of the receiving box body 71, preventing the receiving box body 71 from moving. Simultaneously, the operator can activate the vibration motor 52 via the external controller, which in turn activates the spring supported by the compressed spring 53. The positioning seat 51 vibrates at a high frequency with small amplitude, causing the receiving box body 71 within the multiple limiting shells 54 to vibrate synchronously. This ensures that the material inside the receiving box body 71 is evenly spread within it. At regular intervals, the external controller automatically extends the multi-stage electric telescopic rod 81 forward. The multi-stage electric telescopic rod 81 drives the sliding block 82, which is slidably connected to the support plate 61, to move forward. This, in turn, causes the sliding shell 83, which is slidably connected to the sliding block 82, to move forward synchronously. If the receiving box body 71 is about to be full, the sliding shell 83 will be stopped by the material after advancing a certain distance. At this point, the multi-stage electric telescopic rod 81 continues to drive the sliding block 82 forward, causing relative sliding between the sliding shell 83 and the sliding block 82. Spring 86 will be compressed, and the pressure can be transmitted to pressure sensor 84 through force plate 85. When pressure sensor 84 detects a significant increase in pressure value, external controller can know that the receiving box body 71 has been loaded with sufficient material. External controller can retract multi-stage electric telescopic rod 81 and prompt the staff to replace receiving box body 71 through screen or sound. This is existing technology. Then, the staff can retract the hydraulic cylinder 55 on the upper side of positioning seat 51 through external controller. The hydraulic cylinder 55 drives the locking block 56 to move out of the groove of locking plate 72, thereby releasing the lock of receiving box body 71. The staff can come to the receiving box body 71 and pull handle 73 to move receiving box body 71 through rotating wheel group 74.This device uses a movable locking block 56 in conjunction with a locking plate 72 to lock the receiving bin body 71. A movable sliding block 82 moves the sliding shell 83 forward. Simultaneously, a pressure sensor 84, in conjunction with a force plate 85, detects the extension and retraction of the force spring 86. If the sliding shell 83 is obstructed by material, the force spring 86 is compressed, and the pressure sensor 84 detects the pressure change, indicating that the receiving bin body 71 is full. An external controller can then promptly notify the workers. This device eliminates the need for workers to constantly monitor the receiving bin's status at the processing site and ensures that workers can promptly empty the material when the receiving bin is full, making it a time- and labor-saving solution.
