Description

Technical Field

[0001] This utility model relates to a ceramic tile edge grinding device, belonging to the field of ceramic tile laying auxiliary tools. Background Technology

[0002] Ceramic tiles are a type of building decoration material made primarily from natural minerals such as clay and quartz sand, sintered at high temperatures. They possess advantages such as high hardness, strong wear resistance, and strong corrosion resistance, and are mainly used for the decoration and protection of building walls and floors. During the installation of ceramic tiles, edge grinding is often necessary to improve safety, aesthetics, and construction results, and angle grinders are one of the most frequently used tools in this process. However, existing angle grinders can only grind the outer edges of ceramic tiles. For some inner corners after cutting, the large grinding disc area usually makes grinding impossible. The sharp angles created by cutting not only affect the appearance but also easily scratch workers; furthermore, the grinding process generates dust, which, if inhaled by workers, can harm their health. Utility Model Content

[0005] Furthermore, a positioning platform is provided on the lower side of the grinding shaft, and a pad and a locking ring are connected to the grinding shaft. The pad fits into the positioning platform, and the locking ring is threadedly connected to the grinding shaft. The grinding disc is located between the pad and the locking ring.

[0006] Furthermore, the bottom of the grinding shaft is provided with an insertion hole, the wheel axle is inserted into the insertion hole, and a locking bolt that passes through the wheel axle is threaded onto the side wall of the grinding shaft.

[0007] Furthermore, a protective net corresponding to the exhaust port is connected to the sealing cover.

[0008] Furthermore, the sealing cover is threadedly connected to the dust collector cylinder, the bottom of the sealing cover is provided with an upper mounting groove, the top of the head shell is provided with a lower mounting groove, and the upper and lower ends of the filter cylinder are respectively installed in the upper mounting groove and the lower mounting groove.

[0009] Furthermore, the protective net is installed in the upper mounting groove.

[0010] The advantages of this utility model compared with the prior art are: The ceramic tile edge grinding device described in this utility model is equipped with a grinding wheel, which can grind the inner corners of ceramic tiles, not only ensuring the overall aesthetics of ceramic tiles, but also effectively eliminating the safety hazard of workers being scratched. The ceramic tile edge grinding device described in this utility model is equipped with an exhaust fan, which can create negative pressure inside the dust collection cylinder. This allows the dust generated during grinding to enter the dust collection cylinder through the dust suction hood, dust suction port, dust suction pipe, and dust collection port, and adhere to the filter cylinder. This effectively cleans up the dust generated during grinding, improves the construction environment, and protects the health of workers. The ceramic tile edge grinding device described in this utility model has an exhaust fan mounted on the grinding shaft, which is driven by the motor built into the angle grinder itself. Therefore, it does not require additional power and is more energy-efficient and environmentally friendly. Attached Figure Description
