Description

Technical Field

[0001] The utility model belongs to the technical field of color steel tile repair, and specifically relates to a dust-free grinding device for color steel tiles. Background Art

[0002] Color steel tile repair and polishing refers to a pretreatment process on the surface of color steel tiles before renovation or repair. Color steel tiles, as a commonly used building material, will be eroded by the natural environment when exposed to the outside for a long time, such as wind, rain, ultraviolet radiation, etc., which may cause rust, dirt, and peeling of the old paint layer on the surface. Therefore, a special color steel tile dust-free polishing device is needed to repair it;

[0003] The existing dust-free grinding device for color steel tiles installs a dust suction device around the grinding head and uses the negative pressure principle to effectively capture the dust generated by grinding, thereby achieving a dust-free operation process. Although this design has achieved certain results, it still faces challenges in actual operation. This is mainly because the structural form of color steel tiles is changeable, and the existing standardized negative pressure dust hoods are difficult to fit tightly with all types of color steel tiles, resulting in a small amount of dust still escaping in some areas during the grinding process, affecting the working environment and efficiency. Utility Model Content

[0004] In view of this, the utility model provides a dust-free polishing device for color steel tiles, which can adapt to various shapes and polishing requirements of color steel tiles through a negative pressure dust suction mechanism, and can perform adaptive sealing according to the shape of the color steel tiles, thereby achieving comprehensive sealing, effectively avoiding dust leakage, and realizing a dust-free working environment.

[0006] The grinding assembly comprises a motor arranged in a mounting tube, a grinding head is arranged at the lower end of the output shaft of the motor, and the motor is electrically connected to an external single chip microcomputer.

[0007] The negative pressure dust suction mechanism also includes a spring that is evenly arranged in an annular shape between the lower surface of the conical cover and the bottom wall of the sliding ring, and the springs are respectively movably sleeved on the outside of the vertically adjacent bolt rods; the negative pressure dust suction mechanism also includes a limiting ring plate arranged at the lower end of the outer arc surface of the conical cover, and the upper end of the annular airbag is cooperated with the limiting ring plate.

[0008] Observation windows are arranged in the observation ports which are longitudinally symmetrically arranged in the middle of the outer arc surface of the conical cover.

[0009] An annular anti-wear sleeve is arranged at the lower end of the outer surface of the annular airbag.

[0010] An annular flexible fire baffle is provided at the lower end of the sliding ring.

[0011] The beneficial effects of the above technical solution of the utility model are as follows:

[0012] 1. First of all, according to the various shapes and grinding requirements of color steel tiles, the relevant staff will turn the bolt rod in turn. When the bolt rod turns, it will push the sliding ring to overcome the elastic force of the spring and move down synchronously, so as to adjust the position of the sliding ring to adapt to the various shapes and grinding requirements of color steel tiles. After the adjustment is completed, the relevant staff will hold the conical cover to press the annular airbag against the surface of the color steel tile. The annular airbag can perform adaptive sealing according to the shape of the color steel tile, thereby achieving comprehensive sealing, and the limiting ring plate helps to fix the position of the annular airbag to ensure the sealing effect.

[0013] 2. The relevant staff controls the operation of the motor through an external single-chip microcomputer. The motor output shaft drives the grinding head to rotate, and then grinds the color steel tiles. After starting the grinding, due to the closed design of the conical cover and the annular airbag, the dust generated by the grinding is effectively confined in the cover. At the same time, the telescopic tube is connected to the external vacuum cleaner, and the external vacuum cleaner starts to work and forms a negative pressure environment in the conical cover through the telescopic tube, so as to extract the dust generated in the conical cover, thereby realizing a dust-free working environment, effectively avoiding dust leakage, and keeping the working environment clean.

[0014] 3. The annular flexible fire baffle effectively isolates the potential damage to the annular airbag from sparks and other heat sources, ensuring the safety of the entire grinding operation and the durability of the equipment.

[0015] 4. The observation window allows the operator to observe the grinding process at any time to ensure the quality of work and the status of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
