Grinding machine with a dust removal function

Abstract

The invention provides a grinding machine with a dust removal function, belonging to the technical field of operation. The grinding machine with the dust removal function solves the problems that a cloth bag in the existing grinding machine with the dust removal function is apt to rupture, the service life is short and the existing grinding machine with the dust removal function is troublesome to use. The grinding machine with the dust removal function comprises a worktable, a motor, a dust suction hood and a grinding wheel. A fan below a table board is fixedly arranged on the worktable. An air inlet pipe, an air exhaust pipe, a dust discharge port and a cyclone dust removal mechanism which can separate out dust in dust-containing air and discharge the dust from the dust discharge port are arranged between the fan and the dust suction hood. The air inlet pipe is communicated with the dust suction hood. The air exhaust pipe is communicated with the air inlet of the fan. A dust collection mechanism which is communicated with the dust discharge port, can enable the dust discharge port to be closed and can collect the dust which falls down from the dust discharge port is fixedly arranged on the worktable. The grinding machine with the dust removal function has the advantages of simple structure, reasonable and compact design, low manufacturing cost, good dust removal and noise reduction effect and convenience in dust particle cleaning.

Description

technical field [0001] The invention belongs to the technical field of operations, and relates to a grinding and polishing device, in particular to a dust removal grinder. Background technique [0002] Grinders are commonly used equipment for sharpening various knives and tools. It is mainly composed of a base, a grinding wheel, a motor or other power sources, a bracket and a protective cover. The grinding wheel is arranged on both sides of the base, and the base has a space for accommodating a power source. The power source drives a reducer, and the reducer has a transmission shaft passing through the side of the base for fixing the grinding wheel. Although this grinding wheel machine can complete the grinding workpiece conveniently and smoothly, there are also some defects: because the grinding wheel machine does not have any dust removal device, the dust generated in the process of processing the workpiece diffuses and pollutes the air. occupational disease.

AI Technical Summary

Problems solved by technology

Although this grinding wheel machine can complete the grinding workpiece conveniently and smoothly, there are also some defects: because the grinding wheel machine does not have any dust removal device, the dust generated in the process of processing the workpiece diffuses and pollutes the air. occupational disease

Although the grinder can remove some dust, there are still some defects: 1. The dust removal grinder uses a cloth bag to separate and suspend dust particles in the air or gas. In actual use, the dust is very easy to adhere to the cloth bag. Lead to blockage of filter holes, greatly affecting the filtering effect

Although it is currently possible to use air to blow back the cloth bag intermittently or shake the cloth bag intermittently to remove the dust adhering to the cloth bag, but there is still a problem of troublesome use

2. Under the impact of iron sand, the cloth bag is easy to break, and there is a problem of low service life

3. The dust removal method of the dust removal grinder will inevitably make the dust removal incomplete, and the air will flow back everywhere in the cavity of the workbench, driving the dust deposited in the cavity to fly everywhere in the cavity, and will also be scattered to the outside with the airflow. environment, causing pollution

And as the dust accumulates in the cavity, it is bound to be cleaned regularly. It will be very laborious to clean up under this structure, which will bring a lot of inconvenience to the user.
