Description

Technical Field

[0001] The utility model relates to the technical field of galvanized sheet production, in particular to a galvanized sheet scraping device. Background Art

[0002] During the production process of galvanized sheets, some zinc slag is easily attached to the surface of the zinc layer. In order to ensure that the quality of the galvanized sheets meets the standard requirements, the staff usually scrapes the slag from the galvanized sheets. In order to facilitate the scraping of the galvanized sheets, the staff usually uses a galvanized sheet scraping device. The existing galvanized sheet scraping device usually consists of a base, a scraping plate, a clamping mechanism and a hollow plate.

[0003] For example: The utility model with application number CN201922394637.4 discloses a zinc slag scraping device for a hot-dip galvanized sheet production line, which specifically includes a base, horizontal feet are provided at the four corners of the bottom of the base, the inner cavity of the base is slidably connected with a draw plate through a pulley, a drawing groove is provided on the front side of the draw plate, a hollow plate is provided on the top of the base, a lower limiting mechanism is provided at the central position of the top of the hollow plate, supporting columns are vertically fixedly connected to the left and right sides of the top of the hollow plate, the inner cavities of the two supporting columns are provided with zinc scraping mechanisms, and the tops of the two supporting columns are fixedly connected with horizontal cross bars, and an upper limiting mechanism is provided at the central position of the horizontal cross bar; the galvanized sheet is fixed by the upper limiting mechanism and the lower limiting mechanism, and the zinc scraping mechanisms on the left and right sides can be opened at the same time to scrape zinc on the galvanized sheet, which greatly improves the working efficiency of zinc scraping, reduces the working time of the staff, and provides great convenience for the staff.

[0004] However, as far as the current traditional galvanized sheet scraping device is concerned, in the process of scraping the galvanized sheet, the scraped zinc slag is usually discharged through the hollow plate. However, since the zinc slag has certain viscosity and accumulation, during long-term use, the zinc slag is easy to adhere to the holes of the hollow plate and accumulate, causing blockage of the hollow plate, affecting the discharge effect of the hollow plate on the zinc slag, and is inconvenient to use. Utility Model Content

[0005] In view of this, the utility model provides a galvanized sheet scraping device, which has an extrusion cam which can automatically clean the zinc slag attached to the holes of the hollow plate during the scraping process, and will drive the two control gears to rotate during the movement of the two control racks. At the same time, through the cooperation of the control pawl and the control ratchet, the fixed shaft can drive the extrusion cam to rotate only when the galvanized sheet is released, so as to avoid the shaking of the hollow plate in the process of clamping the galvanized sheet affecting the clamping effect of the galvanized sheet. During the rotation of the extrusion cam, the hollow plate will be intermittently squeezed to make the hollow plate slide. Under the action of the elastic potential energy of the supporting spring itself, when the extrusion cam does not squeeze the hollow plate, the hollow plate will be reset, thereby causing the hollow plate to vibrate and shake off the zinc slag attached to the hollow plate.

[0006] The utility model provides a galvanized sheet scraper device, which specifically comprises: a mounting base; a support frame is fixedly connected to the center of the outside of the mounting base; a mounting frame is fixedly connected to the left part of the top surface of the support frame; a driving motor is fastened and connected to the top surface of the mounting frame with bolts; two groups of guide slide grooves are symmetrically provided in the mounting base; a hollow plate is slidably connected in the two groups of guide slide grooves; a group of support springs are symmetrically fixedly connected to the bottom end surfaces of the two hollow plates; the ends of the two groups of support springs are respectively fixedly connected to the two groups of guide slide grooves; two fixed plates are symmetrically fixedly connected to the top surface of the mounting base; a collection box is slidably connected in the mounting base.

[0007] Optionally, two lifting screws are symmetrically rotatably connected in the support frame; the output shaft of the drive motor is fixedly connected to the left lifting screw; the upper parts of the two lifting screws are fixedly connected to a connecting pulley; the two connecting pulleys are connected by a transmission belt.

[0008] Optionally, the exterior of the two lifting screw rods is threadedly connected to a lifting slider; the inner sides of the two lifting sliders are fixedly connected to a horizontal telescopic rod; and the ends of the two horizontal telescopic rods are fixedly connected to a scraper plate.

[0009] Optionally, an operating rod is rotatably connected to the center of the front end surface of the mounting base; a gear column is fixedly connected to the outside of the operating rod; two control racks are symmetrically arranged at the rear of the mounting base; and both control racks are meshed with the gear column.

[0011] Optionally, a control gear is meshed on the inner side of the two control racks; two fixed shafts are symmetrically slidably connected in the mounting base; the two control gears are respectively fixedly connected to the front of the two fixed shafts; the outsides of the two fixed shafts are symmetrically hinged with a group of control pawls; two groups of control ratchets are symmetrically rotatably connected in the mounting base; the two groups of control pawls are respectively meshed with the two groups of control ratchets; a group of extrusion cams are fixedly connected to the outsides of the two groups of control ratchets; the two groups of extrusion cams are respectively aligned with the positions of the two hollow plates. Beneficial Effects

[0012] When scraping galvanized sheet, the utility model starts the driving motor and moves two scraping plates at the same time through a series of transmissions, so as to scrape galvanized sheet on both sides, thereby greatly improving the scraping efficiency of galvanized sheet and effectively improving the practicability of the scraping device for galvanized sheet.

[0013] By turning the operating lever, the gear column drives the control rack to move, and the control rack drives the fixed clamp to close, so that the galvanized sheet to be scraped can be quickly clamped and fixed. The operation is simple and quick, which is convenient for the subsequent scraping of the galvanized sheet. At the same time, in the process of moving the control rack, it will also drive the control gear to rotate. In the process of rotating the control gear, the hollow plate will vibrate through a series of transmissions to shake off the zinc slag adhered to the holes of the hollow plate, thereby ensuring the discharge effect of the hollow plate on the zinc slag, effectively improving the convenience of the galvanized sheet scraping device, and making it more convenient to use.
