AI Technical Summary

⚠Technical Problem

Existing stone powder spreading equipment cannot achieve powder grading, resulting in poor powder spreading effect, low efficiency, high labor intensity, and difficulty in meeting the production needs of enterprises.

⚗Method used

An automatic filling device for defects in slate was designed, including a conveying device and a grading device. The device uses the different pore sizes of the first and second filter screens to grade the powder. Combined with a roller brush and a flexible scraper, it realizes multi-stage filtration and grading of the powder, ensuring that cavities of different sizes are filled with powder of the appropriate specifications.

🎯Benefits of technology

It enables automated grading and all-round filling of powder, improves powder spreading efficiency, meets the production needs of enterprises, and reduces labor intensity.

Abstract

The application provides a stone slab defect automatic filling device, and relates to the technical field of stone slab repairing devices. The device comprises a conveying device, a feeding device and a grading device. The grading device comprises a support arranged on a frame, at least a first roller brush, a second roller brush, a first filter screen, a second filter screen and a driving device are arranged on the support. The first filter screen is arranged below the first roller brush and is connected to the feeding device. The second filter screen is arranged below the second roller brush. The filter hole diameter of the first filter screen is smaller than that of the second filter screen. The first roller brush is arranged in front of the second roller brush along the advancing direction of the stone slab. The height distance between the first roller brush and the stone slab is higher than that between the second roller brush and the stone slab. The driving device is drivingly connected to the first roller brush and the second roller brush, and is used for driving the first roller brush and the second roller brush to rotate in the same direction. Through the application, the powder laying efficiency can be improved, and the powder grading automation can be realized.
