Description

Technical Field

[0001] This application relates to the technical field of laser cleaning apparatus, and in particular to a cleaning apparatus for galvanized steel sheets. Background Technology

[0002] Galvanized steel sheets, due to the dense oxide film formed by the zinc coating on their surface, possess excellent corrosion resistance and mechanical strength, and are widely used in construction, automobile manufacturing, home appliance production, shipbuilding, and other fields. During the production and processing of galvanized steel sheets, oil, scale, dust, fingerprints, and other contaminants often remain on the surface due to rolling, handling, and storage. If these contaminants are not cleaned in a timely manner, they will not only affect the quality of subsequent painting and welding processes, but may also accelerate the corrosion of the zinc coating during long-term use, reducing the product's lifespan.

[0003] Currently, commonly used galvanized steel sheet cleaning equipment in the industry is mainly divided into three categories: chemical cleaning equipment, high-pressure water cleaning equipment, and manual-assisted cleaning equipment. Chemical cleaning equipment dissolves surface contaminants by spraying acidic or alkaline cleaning agents, followed by rinsing with clean water and drying to complete the cleaning. However, the use of cleaning agents can easily lead to localized corrosion of the galvanized layer (especially at edges and corners), affecting the appearance and corrosion resistance of the steel sheet. On the other hand, wastewater treatment costs are high, and the volatilization of cleaning agents can easily cause environmental pollution in the workshop, failing to meet environmental protection requirements. Utility Model Content

[0004] In order to achieve the goal of cleaning galvanized steel sheets stably and safely, this application provides a cleaning device for galvanized steel sheets.

A first movable seat is slidably mounted on the upper surface of the equipment base, and a first hydraulic cylinder is provided on the equipment base to drive the first movable seat to move back and forth. A second movable seat is mounted on the upper surface of the first movable seat, and a second hydraulic cylinder is provided on the first movable seat to drive the second movable seat to move left and right. A sheet metal processing table is fixedly mounted on the second movable seat. A back panel frame is fixedly mounted on the rear end of the equipment base. A lifting seat is suspended at the head of the back panel frame, and an auxiliary hydraulic cylinder is mounted on the back panel frame to drive the lifting seat to move. A laser cleaning component is fixedly mounted at the lower end of the lifting seat, and a dust collection component is fixedly mounted on the front end of the back panel frame.

[0006] By adopting the above technical solution, the first movable seat is moved back and forth by the first hydraulic cylinder, and the second movable seat is moved left and right by the second hydraulic cylinder. This allows for flexible movement of the sheet metal processing table within a plane, facilitating the adjustment of the galvanized steel sheet's position to meet different cleaning needs. The auxiliary hydraulic cylinder on the backplate frame drives the lifting seat, enabling the laser cleaning component to move up and down, facilitating cleaning operations on galvanized steel sheets at different heights. The dust collection component promptly removes dust and other pollutants generated during the cleaning process, preventing them from drifting into the surrounding environment, thus contributing to environmental protection and collection.

An angle motor can drive the cleaning frame assembly to tilt up and down, facilitating angle adjustment to adapt to different cleaning scenarios. A dust pump connected to the cleaning frame assembly generates suction to remove dust and other contaminants generated during the cleaning process.

[0009] Optionally, the equipment hanger includes a hanging plate and a guide frame for sliding installation of the extension frame. The guide frame is vertically installed on the lower end face of the hanging plate and is fixedly connected to the hanging plate.

A threaded sleeve that mates with the threaded vertical rod 852 is provided in the middle of the frame box 821. The top motor 851 drives the threaded vertical rod 852 to rotate. The threaded vertical rod 852 mates with the threaded sleeve in the middle of the frame box 821, converting the rotational motion into linear motion, thereby realizing the lifting and lowering of the extension frame 82. This drive method has a simple structure and stable transmission.

[0034] The implementation principle of the cleaning device for galvanized steel sheets in this application embodiment is as follows: The galvanized steel sheet to be cleaned is placed on the sheet processing table 4. Based on the position of the galvanized steel sheet and the cleaning requirements, the first movable seat 2 is moved back and forth by the first hydraulic cylinder, and the second movable seat 3 is moved left and right by the second hydraulic cylinder, adjusting the position of the galvanized steel sheet. The auxiliary hydraulic cylinder is activated, driving the lifting seat 6 to move, causing the laser cleaning assembly 7 to descend to a suitable height for cleaning the galvanized steel sheet. Simultaneously, the dust pump is activated, generating suction. The top motor 851 drives the threaded vertical rod 852 to rotate, causing the extension frame 82 to descend and adjusting the height of the cleaning frame assembly 83 to approach the surface of the galvanized steel sheet. As needed, the angle motor 820 is activated, driving the cleaning frame assembly 83 to rotate up and down, adjusting the angle of the cleaning frame assembly 83. The electric cylinder 833 is activated, driving the adsorption ring shell 832 to rotate reciprocally, expanding the adsorption range. During the cleaning process, dust and other pollutants are drawn into the adsorption tank 834 on the lower end face of the adsorption ring shell 832, and then enter the dust removal pump through the connecting hose 836 to achieve dust collection and treatment. After cleaning, the laser cleaning component 7, dust removal pump, each hydraulic cylinder, motor and electric cylinder 833 are turned off in sequence, and the cleaned galvanized steel sheet is removed from the sheet processing table 4.
