Description

Technical Field

[0002] Grinding machine is a common equipment used to sharpen various knives and tools. It is also used for grinding, deburring and cleaning ordinary small parts. When grinding, a large amount of debris and dust will be generated. The dust and debris are adsorbed and collected by the dust removal device. When some dust removal devices for grinding machines are used, the control unit starts the air pump, and the air pump generates suction, so that the dust suction part of the device adsorbs the dust generated by the grinding wheel. The adsorbed gas carries the dust into the interior of the device, and then is filtered through the filter element, so that the dust remains inside the device, and the gas is discharged to the outside of the device. However, the filter element of the device is connected and fixed to the device by bolts, and the replacement of the filter element in the later stage is cumbersome. At the same time, during the use of the filter element, if there is too much dust, it is easy to block the filter holes of the filter element, thereby affecting the dust removal effect of the device on the grinding wheel.

The gear 94 is meshed with the outer gear ring 93 so that the rotating ring 91 drives the cleaning brush strip 92 to rotate around the axis of the filter element 11. During the rotation of the cleaning brush strip 92, it contacts the outer side of the filter element 11 to clean the dust adhered to its surface, avoiding the clogging of the filter holes of the filter element 11 due to dust, resulting in a reduction in the adsorption force of the device.

[0029] The working principle of a dust removal device for a grinding machine provided by the utility model is as follows: when the grinding machine is running, the single-chip microcomputer 3 starts the dual-axis motor 4 so that the output shafts at both ends thereof respectively drive the corresponding grinding wheels 5 to rotate, and the protective shell 6 is used to shield the debris generated during the rotation and grinding of the grinding wheel 5. When the grinding machine is dusted, the single-chip microcomputer 3 starts the induced draft fan 13, and the operation of the induced draft fan 13 generates negative pressure so that the dust suction seat 7 generates suction, and then the dust generated during the grinding of the grinding wheel is adsorbed and collected into the bottom shell 1, and the gas carrying the dust is filtered by the filter element 11 and discharged from the casing 12, and the induced draft fan 13 in the casing 12 is separated from the outside world by the protective net 14. During the dust removal process of the grinding machine, the single-chip microcomputer 3 starts the driving motor 95 so that the output shaft drives the rotating shaft to rotate, and the rotating shaft drives the gear 94 to rotate, and the gear 94 passes through the filter element 11. By meshing with the outer toothed ring 93, the rotating ring 91 drives the cleaning brush strip 92 to rotate around the axis of the filter element 11. During the rotation, the cleaning brush strip 92 contacts the outer side of the filter element 11 to clean the dust adhered to its surface, thereby avoiding the filter holes of the filter element 11 being blocked by dust and causing the adsorption force of the device to be reduced. The sealing strip 16 is used to improve the sealing between the closing door 15 and the bottom shell 1. When replacing the filter element 11, the dial button 83 is turned to drive the locking column 81 away from the locking hole, thereby releasing the lateral movement limit of the filter element 11, and the spring 82 is elastically stretched, and then the filter element 11 is pulled out of the annular seat 10 and replaced and installed. The locking column 81 is plugged into the locking hole of the replaced filter element 11 through the stretching elastic force of the spring 82, thereby limiting the installation of the replaced filter element 11, and the operation is simple.
