Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically to a grinding wheel with a dust removal structure. Background Technology

[0002] A grinding wheel machine is a grinding device that uses a motor to drive a grinding wheel to rotate at high speed for grinding workpieces, deburring, and sharpening cutting tools. Its core components include the grinding wheel, motor, machine base, and protective cover. It is widely used in machining, mold manufacturing, and other fields. When the grinding wheel machine is running, the intense friction between the grinding wheel and the workpiece generates a large amount of metal dust and grinding wheel debris. If the dust is not removed in time, it will not only be inhaled by the operator, causing respiratory diseases such as pneumoconiosis and endangering their health, but the dust will also adhere to the motor, bearings, and other components of the equipment, affecting heat dissipation and lubrication, accelerating equipment wear, and shortening its service life. At the same time, dust in the working environment will reduce visibility, increase the risk of operational errors, and may pollute the surrounding environment. Therefore, dust removal is a necessary measure to ensure the safety of operators, maintain stable equipment operation, and improve the working environment.

[0003] Currently, when dust generated during the operation of a grinding wheel machine is removed by exhaust dust filtration, the filter structure is prone to clogging due to dust accumulation, which reduces filtration efficiency. Therefore, we propose a grinding wheel machine with a dust removal structure. Utility Model Content

[0004] The purpose of this utility model is to provide a grinding wheel machine with a dust removal structure, which can easily remove the dust generated during the operation of the grinding wheel machine, and at the same time avoid the filter screen from being clogged by dust due to long-term use, ensuring dust filtration efficiency and thus ensuring the stable operation of the grinding wheel machine for dust removal. This solves the problem that when the dust generated during the operation of the grinding wheel machine is removed by the exhaust dust filtration method, the filter screen structure is prone to reduced filtration efficiency due to dust clogging after long-term use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding wheel machine with a dust removal structure, comprising a base, a support, a grinding wheel, a protective cover, and a housing. Protective covers are fixedly installed on both sides of the outer surface of the housing. A grinding wheel is installed inside each of the two protective covers, and an opening is provided on the front surface of each of the two protective covers. A filter cartridge and an exhaust fan are fixedly installed inside the support. The input end of the exhaust fan is fixedly connected to the outer surface of the filter cartridge near its lower surface. A suction pipe is fixedly connected to the upper surface of the filter cartridge. Two connecting pipes are fixedly connected to the end of the suction pipe. Connecting valves are connected to the ends of the two connecting pipes, and the ends of the two connecting valves are respectively fixedly connected to the lower surfaces of the two protective covers. A filter screen is installed inside the filter cartridge. A rotating shaft is rotatably installed inside the filter cartridge. An impeller is fixedly connected to the top of the rotating shaft, and a brush plate is fixedly installed on the outer surface of the rotating shaft.

[0006] Preferably, a base is fixedly installed on the upper surface of the support base, and a housing is fixedly installed on the upper surface of the base. A rotating motor is fixedly installed inside the housing, and the two output ends of the rotating motor are respectively fixedly connected to the outer surfaces of two grinding wheels. A switch is fixedly installed on the front surface of the base, and the switch is electrically connected to the rotating motor.

[0007] Preferably, a base is fixedly installed on the lower surface of the support, and bolt holes are provided on the upper surface of the base near the four corners.

[0008] Preferably, a sealing plate is fixedly installed on the lower surface of the filter cartridge, and the sealing plate and the filter cartridge are fixedly connected by bolts, with the filter screen cylinder fixedly installed on the upper surface of the sealing plate.

[0009] Preferably, a limiting ring is fixedly installed on the top of the inner wall of the filter cylinder, and the top of the filter cylinder is located inside the limiting ring.

[0010] Preferably, a dust collection hopper is fixedly installed on the lower surface of the sealing plate, and a dust discharge valve is fixedly installed on the lower surface of the dust collection hopper.

[0011] Preferably, the rear surface of the support base is provided with a cleaning port.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a support base, filter cylinder, exhaust fan, housing, protective cover, opening, connecting pipe, connecting valve, dust suction pipe, filter screen cylinder, impeller, rotating shaft, and brush plate, achieves convenient removal of dust generated during the operation of the grinding wheel machine, while also preventing the filter screen from becoming clogged with dust due to long-term use, ensuring dust filtration efficiency, and thus ensuring stable dust removal effect during the operation of the grinding wheel machine. The workpiece contacts the grinding wheel at the opening, and the grinding wheel performs grinding processing on the workpiece. When the exhaust fan is working, the dust generated during processing is sucked into the protective cover and discharged into the filter cylinder along the connecting valve, connecting pipe, and dust suction pipe. It is filtered out and collected by the filter screen cylinder, and the air flowing inside the filter cylinder drives the impeller to rotate, thereby driving the rotating shaft and brush plate to rotate. The brush plate brushes off the dust adhering to the surface of the filter screen cylinder, thus preventing the filter screen cylinder from becoming clogged.

[0014] 2. This utility model achieves the effect of facilitating the disassembly and cleaning of the filter cylinder by setting a sealing plate and a limiting ring. The sealing plate and the filter cylinder are fixed together by bolts, which facilitates the disassembly of the sealing plate. The filter cylinder is directly fixed to the sealing plate. After the sealing plate is removed, the filter cylinder can be removed from the inside of the filter cylinder for cleaning. During installation, the sealing plate and the filter cylinder are fixed together by bolts, and the top of the filter cylinder is inserted into the limiting ring to fix the filter cylinder inside the filter cylinder.

[0015] 3. By setting up a dust collection hopper and a dust discharge valve, this utility model achieves the effect of facilitating the discharge of the filtered dust from inside the filter cylinder. The dust collected inside the filter cylinder falls into the dust collection hopper, and the dust can be discharged by opening the dust discharge valve. Attached Figure Description
