Description

Technical Field

[0001] The utility model relates to the technical field of metal removal of plastic particles, in particular to a metal removal device which is convenient for removing impurities. Background Art

[0002] In the production of plastic particles, the raw materials contain iron elements, which may be one of the main reasons for the high iron content in plastic particles. Especially in the process of recycling and reusing waste plastics, they are often mixed with many metals, such as iron sheets or iron wires, which can easily cause iron pollution.

[0003] According to a publicly disclosed electromagnetic metal removal device for plastic particles (Announcement No.: CN216506154U), in the above application, the plastic particles are transported by a conveyor belt driven by a driving roller, and the metal impurities mixed in the plastic particles on the conveyor belt are adsorbed by the electromagnetic roller, so that the plastic particles can be quickly removed. When the plastic particles fall into the plastic particle chamber from the edge of the conveyor belt, the metal impurities are conveyed to the lower layer of the conveyor belt. After the metal impurities are separated from the electromagnetic roller, they can automatically fall off into the drawer of the metal impurity chamber, and the efficiency of metal removal from plastic particles is high.

[0004] However, in actual use of the above-mentioned equipment, plastic particles are transported through a conveyor belt, and metal impurities mixed in the plastic particles on the conveyor belt are adsorbed by an electromagnetic roller. However, the plastic particles will accumulate on the surface of the conveyor belt, and the electromagnetic roller can only adsorb the metal impurities on the surface of the plastic particles, while the metal impurities inside the accumulated plastic particles will be missed, thereby reducing the impurity removal effect of the plastic particles. In view of this, we propose a metal removal device that is easy to remove impurities. Utility Model Content

[0026] In the embodiment of the utility model, the side wall of the shell 1 is fixedly connected with the end of the motor 5, the output end of the motor 5 is fixedly connected with the end of the rotating shaft 6, the other end of the rotating shaft 6 is fixedly connected with the end of the cam 7, the side wall of the cam 7 is provided with a protrusion 8, the top of the protrusion 8 is fixedly connected with the bottom of the mounting frame 9, the inner surface of the mounting frame 9 is fixedly connected with the outer surface of the electromagnetic plate 10, the surface of the electromagnetic plate 10 is penetrated with a through hole 11, the top of the mounting frame 9 is fixedly connected with the bottom of the guide rail 12, the outer surface of the guide rail 12 is slidably connected with the outer surface of the guide block 13, the top of the guide block 13 is provided with a slide groove 14, the inside of the slide groove 14 is slidably connected with the bottom of the slider 15, the top of the slider 15 is hinged with the output end of the electric push rod 16, the fixed end of the electric push rod 16 is fixedly connected with the bottom of the fixed plate 17, the inner wall of the shell 1 is fixedly connected with the fixed end of the telescopic rod 18, the outer wall of the telescopic rod 18 is provided with a spring 19, and the end of the spring 19 is fixedly connected with the side wall of the contact plate 20.

[0027] In one embodiment of the utility model, the end of the fixed plate 17 is fixedly connected to the inner wall of the shell 1, the end of the spring 19 away from the contact plate 20 is fixedly connected to the inner wall of the shell 1, the bottom of the electromagnetic plate 10 is fixedly connected to one side of the connecting plate 21, and the other side of the connecting plate 21 is hinged to the top of the moving block 22, and the bottom of the moving block 22 is slidably connected to the inside of the moving groove 23, and the moving groove 23 is located at the top of the support plate 24. The top of the support plate 24 is provided with a moving groove 23, and the end of the support plate 24 is fixedly connected to the inner wall of the shell 1, the connecting plate 21 is located on the side of the electromagnetic plate 10 away from the guide rail 12, the electromagnetic plate 10 is configured to pass the electromagnet, and the through holes 11 are equidistantly distributed on the surface of the electromagnetic plate 10, and the bottom of the shell 1 is provided with an inclined plate, which is inclined toward the side close to the discharge port 3.

[0028] In the present invention, when in use, plastic particles are put into the shell 1 through the feed port 2. At this time, the electromagnetic plate 10 is in a power-off state, and the motor 5 is turned on. The motor 5 drives the rotating shaft 6 to rotate so that the cam 7 reciprocates and squeezes the protrusion 8. At this time, the mounting frame 9 is forced to drive the guide block 13 to slide on the guide rail 12. At the same time, the moving block 22 slides inside the moving groove 23.

When the cam 7 is not in contact with the protrusion 8, the spring 19 drives the telescopic rod 18 to restore the deformation so that the contact plate 20 pushes the mounting frame 9 to reset, thereby allowing the mounting frame 9 to drive The electromagnetic plate 10 shakes in parallel inside the shell 1, so that the plastic particles quickly pass through the through hole 11 and fall to the bottom of the shell 1, and the metal impurities will be adsorbed on the surface of the electromagnetic plate 10. When the above steps are repeated, the motor 5 is turned off and the electric push rod 16 is turned on. The electric push rod 16 continues to drive the slider 15 to move upward. At this time, the slider 15 will slide inside the slide groove 14 to pull the guide block 13, so that one end of the electromagnetic plate 10 rises and tilts toward one side of the impurity discharge hole 4, and then the electromagnetic plate 10 is powered off. After the power is turned off, the electromagnetic plate 10 no longer generates magnetism that adsorbs the metal impurities, and then the metal impurities slide through the inclined electromagnetic plate 10 to the impurity discharge hole 4 for discharge, and finally the impurity-discharging plastic particles are completely discharged through the discharge port 3.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
