Description

Technical Field

[0001] The utility model relates to the technical field of galvanized steel plate manufacturing equipment, in particular to a slag scraping device for galvanized steel plates. Background Art

[0002] A galvanized steel plate is a welded steel plate with a hot-dip galvanized or electro-galvanized layer on its surface, which is generally widely used in construction, household appliances, vehicles, ship containers, mechanical and electrical industries, etc. Galvanized steel plates can be divided into hot-dip galvanized steel plates, alloyed galvanized steel plates, electro-galvanized steel plates, single-sided galvanized, double-sided differential galvanized steel plates, as well as alloy and composite galvanized steel plates according to production and processing methods. In the process flow of galvanized steel plates, it includes: workpieces, degreasing, water washing, pickling, water washing, dipping in fluxing agent, preheating by baking, hot galvanizing, finishing, cooling, passivation, rinsing, drying, etc. Among them, after the galvanized steel plate undergoes the hot galvanizing process, it will pass through a conveying device composed of multiple conveying rollers, and the conveying device conveys the galvanized steel plate to a drying device for drying treatment. During the conveying process, zinc slag will be entrained on the surface of the galvanized steel plate. If the galvanized steel plate passes through the conveying roller and generates a force with the roller surface of the conveying roller, indentations will be left on the surface of the galvanized steel plate, resulting in a decline in the quality of the galvanized steel plate.

[0003] After retrieval, a Chinese patent discloses a slag scraping device for galvanized steel plates (authorization publication number CN210560679U), which includes a frame body and an upper fixing rod and a lower fixing rod that are respectively connected to the frame body and arranged in parallel. The upper fixing rod and the lower fixing rod respectively extend above and below the galvanized steel plate. An upper slag scraping plate and a lower slag scraping plate with ends abutted against the upper surface and the lower surface of the galvanized steel plate are respectively arranged at the bottom end of the upper fixing rod and the top end of the lower fixing rod. A chip collecting groove for collecting zinc slag is arranged below the lower slag scraping plate. Although this patented technology solves the problem of the low slag cleaning effect of the slag scraping device.

[0004] However, the above device still has some disadvantages in actual use. The more obvious one is that although the above device can achieve double-sided slag scraping at the same time, when adjusting the position of the scraping plate, manual adjustment is required, which is rather inconvenient. Moreover, some zinc slag adheres firmly to the steel plate.
