Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a magnetic separator for effectively separating metal impurities in plastic particles. Background Art

[0002] In the actual production process, surface contamination of plastic particles and internal wear of equipment are likely to produce some iron filings, which are likely to cause quality abnormalities during use. The Chinese utility model patent, authorization announcement number "CN216173189U", discloses a magnetic device for collecting impurities for modified plastic production. The front and rear side walls of the particle conveyor are respectively installed with support frames by bolts; shelves are installed between the support frames by bolts; a baffle is welded on the top of the shelf; a finished product box and a waste box are provided on the top of the shelf; a magnetic separation structure is provided between the particle conveyor and the conveyor belt; a feeding structure is provided on the top of the particle conveyor; an impurity removal structure is installed between the two support frames on the right side, so that metal particles and plastic particles are separated more effectively, ensuring the quality of the modified plastic finished product. After the mixed raw materials are magnetized, the metal particles and plastic particles are collected separately, which improves practicality and separation accuracy.

[0003] In the above technical solution, the mixed particles will fall onto the conveyor belt for transportation, and the fine metal particles electrostatically adsorbed on the surface of the conveyor belt will be scraped off the surface of the conveyor belt under the action of the scraper and collected in the waste box, while the plastic particles will fall directly at the left end of the conveyor belt and fall into the interior of the finished product box to be collected. However, the above technical solution still has certain defects. For example, the above equipment scrapes the fine metal particles on the surface of the conveyor belt off the surface of the conveyor belt through the scraper, and the fine metal particles are collected in the waste box. However, when the scraper is worn out due to long-term use and needs to be disassembled and replaced, the staff needs to carry a rotating tool to disassemble it, which greatly increases the workload of the staff and reduces the disassembly efficiency of the scraper. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a magnetic separator for effectively separating metal impurities in plastic particles. The magnetic separator can solve the problem that the equipment scrapes the fine metal particles on the surface of the conveyor belt off the surface of the conveyor belt through a scraper and collects them in a waste box. However, when the scraper is worn out after long-term use and needs to be disassembled and replaced, the staff needs to carry a rotating tool to disassemble it, which greatly increases the workload of the staff and reduces the disassembly efficiency of the scraper.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a magnetic separator for effectively separating metal impurities in plastic particles, comprising a support base, a screen box, a vibration motor, and an electric motor, wherein a transmission belt is installed on the upper surface of the support base;

[0027] Wherein, the two ends of the return spring are respectively fixedly connected to one end of the corresponding limit rod.

[0028] Compared with the prior art, the beneficial effects of the utility model are:

This avoids the need for workers to disassemble it with the help of special tools, effectively reduces the workload of workers, and improves the efficiency of scraper disassembly.

[0030] (2) The magnetic separator can effectively separate metal impurities in plastic particles. The scraper can scrape the metal particles on the transmission belt and then make the metal particles fall into the drawer for unified collection. This avoids the need for workers to collect them manually, effectively improves the work efficiency of the workers, and greatly improves the practicality and effectiveness of the equipment.
