Description

Technical Field

[0001] The utility model relates to the field of dust covers, in particular to a grinding wheel dust cover. Background Art

[0002] The electric grinding wheel is a commonly used grinding device that uses a motor to drive the grinding wheel to rotate at high speed to grind and polish the workpiece. During the grinding process, a lot of dust and waste will be generated, so dust prevention measures need to be taken during the operation of the grinding wheel.

[0003] The existing grinding wheel dust prevention measures can refer to the patent document with the announcement number CN217966214U. The above patent document discloses a surface burr treatment device for powder feeding roller processing. By setting a grinding and dust removal structure, a pipe is connected between the grinding wheel dust cover and the collection box, and the dust is brought into the connecting pipe by the rotation of the grinding wheel.

[0004] However, by using a half-covered protective cover that also serves as a dust cover, it is difficult for dust to enter the connecting pipe in the absence of external force, but it will still splash outward under the vibration generated by grinding. Utility Model Content

[0017] By adopting the above technical solution, when processing iron and nickel products, an electromagnet is provided on the inner wall of the recycling box. When the electromagnet is turned on, it generates a magnetic force that can adsorb powders generated by ferromagnetic materials such as iron chips, further improving the collection efficiency of waste chips; when the grinding wheel stops working, the electromagnet is powered off. After losing the magnetic effect, the previously adsorbed powders can fall downward and accumulate on the bottom wall of the recycling box.

[0018] Further, the cover body is slidably connected to the recycling box.

[0019] By adopting the above technical solution, the sliding connection structure is simple and convenient for opening and closing the cover body.

[0026] Further, a contact switch for controlling the electromagnet is provided on the baffle. An electric contact is provided on the cover body, and the electric contact abuts against the contact switch to make the electromagnet electrically conductive.

[0027] By adopting the above technical solution, contact switches and electrical contacts are respectively arranged on the baffle and the cover body, and the on and off of the electromagnet is controlled by opening and closing the cover body, so that the electromagnet can be automatically energized according to the use state of the dust cover, thereby simplifying the use steps. When the cover body is closed, the grinder is running, and the electromagnet is energized to remove dust; when the grinder stops running and the cover body is opened, the electromagnet is automatically de-energized.

[0028] Furthermore, the cover is made of a hard transparent material.

[0029] By adopting the above technical solution, the hard cover can provide mechanical strength and serve as a protective cover while preventing dust, and the transparent material makes it easy to observe the grinding condition of the grinder.

[0040] The following will combine the attached Figure 1-4 to clearly and completely describe the technical solution of this application.

[0041] The embodiment of this application discloses a dust-proof cover for a grinding wheel.

[0042] Referring to Figure 1 , a dust-proof cover for a grinding wheel is provided on the outer periphery of the grinding wheel, mainly including two parts: a recycling bin 1 and a cover body 2. The cover body 2 is movably connected to the recycling bin 1. The recycling bin 1 is located below the grinding wheel 10 and has an open top. The cover body 2 is hermetically closed above the recycling bin 1. The recycling bin 1 and the cover body 2 form a closed space to prevent waste chips from spraying outwards, improve the dust-proof effect, and try to make all waste chips fall into the recycling bin 1, thereby improving the recycling efficiency. At the same time, the dust-proof cover composed of the recycling bin 1 and the cover body 2 also serves as a protective cover to prevent accidental detachment during the operation of the grinding wheel 10 and cause personal injury.

[0043] Referring to Figure 1 , the recycling bin 1 is in the shape of a flat square box, the grinding wheel is located inside the recycling bin 1, and the rotating shaft of the grinding wheel 10 extends into the recycling bin 1 to be connected to the grinding wheel. The cover body 2 is made of hard transparent material, and the cross-section of the cover body 2 is in a C shape and is slidably connected to the top of the recycling bin 1. The hard cover body 2 can provide mechanical strength and serve as a protective cover while dust-proofing. The transparent material is convenient for observing the grinding situation of the grinding wheel 10. In this embodiment, the cover body 2 is made of acrylic material.

[0044] Referring to Figure 1 , Figure 2 , a baffle 14 is provided on the top of the recycling bin 1. The baffle 14 is slightly larger than the cross-section of the cover body 2. The baffle 14 abuts against the cover body 2 and plays a role of limiting and sealing at the same time. A chute 21 is opened along the length direction at the bottom edge of the cover body 2, and a flange 15 is correspondingly provided on the recycling bin 1. The flange 15 is slidably matched with the chute 21. Inverting the chute 21 above the flange 15 can尽量 avoid waste chips from depositing inside the chute 21. It is preferably to set the surfaces of both the flange 15 and the chute 21 to be arc-shaped, which is beneficial for waste chips to slide along the surface of the flange 15, reduce waste chip deposition, and also make the sliding of the cover body 2 smoother. A brush 22 facing the flange 15 is also provided on the cover body 2. The brush 22 is located at the end of the chute 21. Each time the cover body 2 is slid open and closed, it is equivalent to cleaning the joint, and尽量 avoid waste chips from accumulating and causing the cover body 2 to slide不畅. A through hole is opened on the baffle 14, and the fixture 20 is passed through the through hole, which is convenient for holding the fixture 20 to adjust the position and angle of the workpiece during grinding.

[0045] Reference Figure 3 , Figure 4 The bottom of the recycling box 1 is funnel-shaped, and electromagnets 13 are provided on all the surrounding side walls. When processing iron and nickel products, the electromagnet 13 is turned on to generate magnetic force to adsorb the powder generated by ferromagnetic materials such as iron filings, further improving the collection efficiency of waste chips; the grinding machine 10 stops working, and then the electromagnet 13 is powered off. After losing the magnetic effect, the previously adsorbed powder can fall downward and be concentrated on the bottom wall of the recycling box 1. A contact switch 141 is provided on the side of the baffle 14 facing the cover body 2, and an electrical contact 23 is provided on the cover body 2. The electrical contact 23 abuts against the contact switch 141 to make the electromagnet 13 electrically conductive, so that the opening and closing of the cover body 2 is used to control the on and off of the electromagnet 13, simplifying the use steps, so that the electromagnet 13 can be automatically powered on or off according to the use status of the dust cover.

[0046] Reference Figure 3 , and also includes an air extraction device 3. A connecting port 11 is opened at the center of the bottom of the recycling box 1. The connecting port 11 is connected to the air pump 31 of the air extraction device 3 through a vent pipe 32. The air extraction device 3 can use airflow to drive waste chips to fall into the recycling box 1, improve the waste chip collection efficiency, and minimize the waste chips adhering to the cover body 2. A filter 12 is provided at the connecting port 11, which can prevent waste chips from entering the air extraction device 3 as much as possible. In this embodiment, the filter 12 is a sponge, and the sponge is wrapped with a breathable non-woven fabric.
