Description

Technical Field

[0001] The utility model relates to the technical field of metal detectors, in particular to a metal detector for automatically separating metals. Background Technique

[0002] A metal detector is a device specifically designed to detect whether there are metal impurities in products or materials, and is widely used in many industries such as food, pharmaceuticals, chemicals, plastic recycling, textiles, etc. When the traditional metal detector is in use, when it detects an item with metal passing through, it gives an alarm prompt, and then manual sorting is carried out, which is time-consuming and laborious. Moreover, if there are metal impurities remaining on the conveyor belt, it is easy to cause the equipment to be insensitive to detection. To ensure the accuracy of equipment use, manual cleaning needs to be carried out regularly, which is inconvenient to use. Content of the Utility Model

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, a metal detector for automatically separating metals, comprising a workbench 1, a cleaning component, a separating component, a metal detector 27 and a conveying component. The conveying component includes a first motor 2, a driving roller 3, a driven roller 4 and a conveyor belt 5. A conveying groove is provided on the workbench 1. The driving roller 3 and the driven roller 4 are respectively rotatably provided on the front and rear sides of the conveying groove. The conveyor belt 5 is sleeved on the driving roller 3 and the driven roller 4. The output end of the first motor 2 penetrates through the side wall of the workbench 1 and is connected to the driving roller 3. Above one end of the workbench 1 near the driving roller 3, a cleaning component for cleaning the conveyor belt 5 is provided. The cleaning component includes a support frame 6, a lifter 7, a cleaning frame 8, a cleaning roller 9 and a second motor 10. The support frame 6 is provided on the two side walls of the workbench 1. The lifter 7 penetrates through the top wall of the support frame 6 and is connected to the cleaning frame 8. A cleaning roller 9 for cleaning the conveyor belt 5 is further provided below the cleaning frame 8. A second motor 10 for driving the cleaning roller 9 to rotate is also provided on the cleaning frame 8. A metal detector 27 is provided in the middle part of the workbench 1. The separating component includes a guiding plate 11, a pusher 12, an extension plate 13, a receiving table 14 and a receiving frame 15. One end of the guiding plate 11 is connected to the workbench 1. A plurality of groups of extension grooves are provided at the end of the guiding plate 11 away from the workbench 1. The pusher 12 is provided on the bottom wall of the guiding plate 11. The extension plate 13 is in an inverted L shape. The output end of the pusher 12 is connected to the bottom wall of the extension plate 13. A plurality of groups of extension teeth inserted into the extension grooves are provided on the extension plate 13. The receiving frame 15 is provided at one end of the receiving table 14 close to the workbench 1.

[0023] At first, the lifter 7 is in a contracted state and the pusher 12 is in an extended state. The workbench 1 provides stable support for the driving roller 3 and the driven roller 4. The material is placed on the conveyor belt 5. The first motor 2 is started. The first motor 2 drives the driving roller 3 to rotate. The conveyor belt 5 drives the material to pass through the metal detector 27 under the support of the driving roller 3 and the driven roller 4. If the material does not contain metal, the material passes through the guiding plate 11, the extension plate 13 and falls on the receiving table 14 for transfer. It should be noted that at this time, the extension grooves of the guiding plate 11 are exposed. The width and length of the loaded material are both greater than the width of the extension grooves, which does not affect the normal feeding of the material. If the material contains metal, the pusher 12 becomes in a contracted state. At this time, the extension plate 13 is inserted into the guiding plate 11, and the material falls into the receiving frame 15, realizing the automatic separation of the material with metal. After being used for a period of time, it is inevitable that foreign objects will fall on the conveyor belt 5, affecting the detection result of the metal detector 27. At this time, the feeding is stopped, the lifter 7 is started, and the lifter 7 drives the cleaning frame 8 to move downward under the support of the support frames with hollow holes on the left and right sides. The second motor 10 is started, and the second motor 10 drives the cleaning roller 9 to clean the material. In this embodiment, both the first motor 2 and the second motor 10 adopt servo motors with stable operation.

[0024] When using only the cleaning roller 9 in the above structure, it is inconvenient to thoroughly clean the conveyor belt 5, and the remaining impurities will still affect the detection result of the metal detector 27. To solve the above problems, the cleaning assembly further includes a liquid supply assembly. The liquid supply assembly includes a liquid supply tank 16, a liquid supply pump 17, a connecting pipe 18, and an output head 19. The liquid supply tank 16 is arranged on the top wall of the support frame 6. One end of the liquid supply pump 17 is connected to the liquid supply tank 16, and the other end of the liquid supply pump 17 is connected to the output head 19 on the cleaning frame 8 through the connecting pipe 18. Several groups of liquid outlet heads are arranged at one end of the output head 19 close to the cleaning roller 9. The liquid supply pump 17 sends the cleaning liquid in the liquid supply tank 16 into the output head 19 through the connecting pipe 18 and then outputs it from the liquid outlet heads. At this time, the cleaning roller 9 with the cleaning liquid stably cleans the conveyor belt 5.

[0025] In the actual use of the above structure, it is found that the waste liquid is likely to affect the working environment. Therefore, a waste liquid collection assembly is further arranged on the workbench 1. The waste liquid collection assembly includes a guiding edge 20, a waste liquid box 21, a moving assembly, and a handle 22. The guiding edge 20 is arranged on the top wall of the waste liquid box 21. The moving assembly is arranged at the four corners below the waste liquid box 21. The handle 22 is arranged on the front surface of the waste liquid box 21. A storage groove adapted to the guiding edge 20 and the waste liquid box 21 is arranged on the bottom wall of the workbench 1. The waste liquid box 21 is pushed by the handle 22. The moving assembly includes universal wheels 23 and brakes 24. The universal wheels 23 are arranged at the four corners below the waste liquid box 21, and the brakes 24 are arranged on the periphery of the universal wheels 23. The universal wheels 23 ensure the stable movement of the waste liquid box 21. The guiding edge 20 is inserted into the storage groove, and then the universal wheels 23 are locked by the brakes 24. The waste liquid falls into the waste liquid box 21. A drain pipe 25 is further arranged on the bottom wall of the waste liquid box 21, and a switch valve 26 is arranged on the drain pipe 25. When the switch valve 26 is opened, the waste liquid is discharged from the drain pipe 25, which is convenient to use.
