The utility model discloses an adjustable scraper structure for die cutting waste discharge equipment, which belongs to the technical field of waste discharge equipment and comprises a support plate, a plurality of mounting holes are arranged on the support plate, two track grooves are fixed on the upper surface of the support plate, the two track grooves are obliquely and symmetrically arranged, and the mounting holes are communicated with the mounting holes. A fixing block is movably arranged in the track groove, two mounting plates are detachably mounted in the track groove, and a guide rod is detachably mounted between the two mounting plates; the inclined rail groove is matched with the fixing block, the locking screw, the rotating shaft, the fixing seat, the fixing screw and the locking screw for use, so that the angle of the end opening of the scraper can be freely adjusted in a large range of a sector until the optimal effect is achieved, local parts of the product can be firstly removed by adjusting the angle of the scraper aiming at the wide product with the small distance, and then the product can be completely removed. And the waste is gradually discharged along the product direction, the waste discharging rate is high, and the phenomena of material breakage, discharging leakage and product missing during waste discharging are effectively avoided.

This application relates to the field of screen printing technology and discloses a screen printing device for the production of safety helmets, comprising: a support frame, serving as the basic component of the overall device for supporting and assembling various processing mechanisms and their subordinate structural components; a rotating clamping mechanism, disposed inside the support frame, for securely clamping the safety helmet; a synchronous adjustment mechanism, disposed on one side of the outer wall of the support frame, for synchronously adjusting the position of the ink filaments; and a scraping mechanism, fixedly connected to the top of the support frame, for scraping the ink filaments on different outer walls of the safety helmets. The rotating clamping mechanism includes a fixed frame. By setting up the scraping mechanism, the inner arc of the scraper can be adjusted during clamping and adjustment inside the safety helmet, thereby increasing the contact area when the scraper scrapes different outer walls of the safety helmet, thus improving the printing quality of the screen printing and accelerating the ink accumulation speed, thereby further improving the printing effect.
