Description

Technical Field

[0001] The utility model relates to the technical field of ink scrapers, in particular to an ink scraper for a screen printer. Background Art

[0002] When the screen printing device is working, it can be roughly divided into three main processes: ink return, printing and ink collection. That is, first drop excess ink on the screen and use a scraper to lightly scrape the screen to evenly apply the ink on the screen, then use the scraper to scrape the screen again to allow the ink to pass through the mesh holes and print onto the printed object, finally use the scraper to lightly scrape the screen to recover the residual ink.

[0003] When the scraper blade is not in use, it is still in the external environment, which can easily cause dust and particles to adhere to the surface of the ink scraper. This phenomenon may affect the cleanliness of the scraper and make the scraper easily wear when it scrapes across the screen. Therefore, it is necessary to develop an ink scraper for screen printing machines. Utility Model Content

When the protective cover 140 is located at the top of the mounting frame 100, the inner end of the protective cover 140 is magnetically adsorbed to the magnetic sheet 150, thereby appropriately improving the stability of the protective cover 140; magnetic sheets 160 for magnetic adsorption to each other are provided at the end portions of the two protective covers 140. When the ends of the two protective covers 140 are close to each other and fit together, the area formed by the two protective covers 140 wraps the mounting strip 210 therein, and the stability of the protective cover 140 is improved after being adsorbed by the two magnetic sheets 160.

[0033] Furthermore, the locking assembly includes a transverse mounting opening 230 symmetrically opened on the front side of the mounting frame 100, a fixing rod 240 is fixedly provided on the inner side wall of the mounting opening 230, an "L"-shaped plug block 250 is slidably provided on the rod body of the fixing rod 240, and a slot hole 270 for the plug block 250 to be inserted vertically and then moved horizontally is symmetrically opened on the front side and top of the mounting strip 210, a transverse spring 260 is provided between the side wall of the plug block 250 and the side wall of the mounting opening 230, and the gap of the rod body of the fixing rod 240 passes through the inner side of the spring 260. When the blade 220 needs to be disassembled and replaced, the plug block 250 is firstly moved horizontally to compress the spring 260, so that the plug block 250 is horizontally pulled out from the hole of the slot hole 270, and then the mounting strip 210 can be separated from the inside of the mounting groove 200 in the vertical direction, so as to facilitate the replacement of the blade 220.

[0034] Furthermore, the height adjustment component is an electric telescopic rod arranged in the middle of the top wall of the mounting frame 100, and the output end of the electric telescopic rod is movable in the vertical direction. The height of the mounting frame 100 can be adjusted by the electric telescopic rod, thereby facilitating the disassembly of the mounting bar 210 and the rotation of the protective cover 140.

[0035] Furthermore, the height adjustment component includes a vertical fixed cylinder 300 symmetrically arranged in the middle of the top wall of the mounting frame 100, a vertical rotating rod 310 is rotatably arranged at the center of the bottom wall of the inner cavity of the fixed cylinder 300, a screw rod 320 is arranged at the upper end of the rotating rod 310, a vertical lifting cylinder 330 is slidably arranged at the upper end and the inner cavity of the fixed cylinder 300, the rod body of the screw rod 320 is threadedly connected with the lifting cylinder 330 for transmission, a bevel gear 1 340 is arranged on the rod body of the rotating rod 310, and a horizontal driving rod 350 is rotatably penetrated through the side walls of the two fixed cylinders 300, the end of the driving rod 350 is located in the inner cavity of the fixed cylinder 300 and is provided with a bevel gear 2 360 meshing with the bevel gear 1 340, and the rod body of the driving rod 350 A knob 370 is provided, and a vertical limiting groove 380 is symmetrically provided on the inner cavity side wall of the fixed cylinder 300.

After the driving rod 350 and the bevel gear 2 360 are rotated by the knob 370, the rotating rod 310 and the screw 320 are driven to rotate by the bevel gear 1 340. The lifting cylinder 330 is restricted by the limiting block 390 and the limiting groove 380 and will not rotate, but its height and the height of the adjustable mounting frame 100 are adjusted to facilitate the disassembly of the mounting strip 210 and the rotation of the protective cover 140. In addition, a mounting plate is commonly provided on the top of the two lifting cylinders 330, and mounting holes are provided around the mounting plate to facilitate the installation of the device.
