Then the hydraulic cylinder 15 will continue to drive the test block to descend, the elastic plate 16 will bend and move to the lower part of the limiting rod 53, then the elastic plate 16 will press against the upper side of the fixing block 473, the rack 47 will descend and drive the gear 46 and the screw rod 45 to rotate, the screw rod 45 will drive the sliding cylinder 44 and the sliding rod 42 to slide along the extending direction of the screw rod 45, the sliding rod 42 will slide in the sliding cylinder 44 and drive the sliding block 41 and the cleaning piece 43 to slide along the extending direction of the inclined sliding rail 4; the moving speed of the cleaning member 43 in the vertical direction coincides with the lowering speed of the lower platen 14, so that the cleaning member 43 will slide in the horizontal direction with respect to the lower platen 14.
In the sliding process of the cleaning piece 43, the two groups of saw blades 432 scrape off the broken slag, the broken slag is prevented from adhering to the lower pressing plate 14, and then the brush 433 cleans the scraped broken slag into the collecting box 3. When the cleaning member 43 is separated from the upper surface of the lower pressing plate 14, the sliding block 41 will abut against the first stopper 48 on the lower side, so that the sliding rod 42, the sliding cylinder 44, the cleaning member 43, the screw rod 45, the gear 46 and the rack 47 all stop moving, at this time, the hydraulic cylinder 15 will drive the lower pressing plate 14 to continue to descend, and the elastic plate 16 will bend and move to the lower side of the fixing block 473.
Subsequently, the hydraulic cylinder 15 will drive the lower platen 14 to ascend, the elastic plate 16 will abut against the lower surface of the fixing block 473 and drive the fixing block 473 and the rack 47 to ascend, the rack 47 will drive the gear 46 and the screw rod 45 to rotate reversely, the screw rod 45 will drive the sliding cylinder 44 and the sliding rod 42 to slide reversely, the sliding rod 42 will slide in the sliding cylinder 44 and drive the sliding block 41 and the cleaning piece 43 to slide reversely, so the cleaning piece 43 will ascend obliquely and clean the broken slag on the upper surface of the lower platen 14 into the collecting box 3 again.
When the cleaning element 43 is separated from the upper surface of the lower pressing plate 14 again, the sliding block 41 will abut against the first stop 48 on the upper side, so that the sliding rod 42, the sliding cylinder 44, the cleaning element 43, the screw rod 45, the gear 46 and the rack 47 all stop moving; at this time, the hydraulic cylinder 15 will drive the lower platen 14 to continue to rise, the elastic plate 16 will bend and move to the upper side of the fixing block 473, then the hydraulic cylinder 15 will stop driving the lower platen 14 to rise, and at this time, the lower platen 14 will be right opposite to the opening 21, so that a worker can conveniently place a new test block on the lower platen 14.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
