The invention is mainly used for conveying a plurality of material plates 4 stacked on a platform 1 to a workbench surface of a material opening device for material opening; according to the invention, the thickness of the material plate 4 is uniform, the triangle similarity principle is utilized, the length of the inner scissor arm 18/the length of the connecting rod 15 = the vertical distance between the upper end of the inner scissor arm 18 and the underframe 2, the vertical distance between one end of the connecting rod 15 and the limiting block 16, which are rotationally connected, and the sliding shaft 14, so that the ratio between the inner scissor arm 18 and the connecting rod 15 can be calculated by measuring the length of the inner scissor arm 18 and the length of the connecting rod 15 respectively, and then the height of the limiting block 16 to be lifted or lowered can be determined according to the thickness of the material plate 4, so that the stretching amount of the hydraulic cylinder 17 can be calculated according to the formula, the hydraulic cylinder 17 is controlled through a control system, and finally, the lifting or lowering height of the limiting block 16 can be accurately controlled, so that when the topmost material plate 4 is conveyed under the action of friction force of the conveying belt 5, the rest material plates 4 can be limited on the platform 1 under the limiting effect of the limiting block 16, and continuous operation can be realized.
Specifically, an operator inputs the material plates 4 into a control system according to the thickness of the material plates 4 and the number of the material plates 4 stacked on the platform 1, and sets a program through the control system, and the control system controls the hydraulic cylinder 17 to work and drives the platform 1 to ascend through the scissor assembly, and simultaneously, the limiting block 16 moves upwards along with the hydraulic cylinder until all the material plates 4 except the topmost material plate 4 can be limited by the limiting block 16; the supporting plate 9 slides downwards along the vertical plate 6 under the driving of the linear driver 8, when the topmost material plate 4 touches the travel switch 10, the travel switch 10 starts and controls the linear driver 8 to stop working, at the moment, the material plate 4 contacts with the surface of the conveying belt 5, the conveying belt 5 starts to drive, and the material plate 4 is conveyed from the platform 1 to the working table of the material cutting equipment through friction force; when the topmost material plate 4 is conveyed, the control system controls the hydraulic cylinder 17 to work again and drives the platform 1 to descend by a certain height through the scissor assembly, and the limiting block 16 moves downwards along with the platform, so that the next material plate 4 is separated from the limiting of the limiting block 16; the supporting plate 9 slides downwards for a certain distance along the vertical plate 6 again under the drive of the linear driver 8, the steps are repeated, the material plates 4 are conveyed onto the workbench surface of the cutting equipment from the platform 1 through friction force, and accordingly the reciprocating operation is achieved, a plurality of material plates 4 are sequentially conveyed from top to bottom, and the orderly development of the cutting work is facilitated.
The linkage of stopper 16 and platform 1 lift is specifically: as shown in fig. 1,3 and 6, in the first embodiment, the control system controls the hydraulic cylinder 17 to work, and when the inner scissor arm 18 slides linearly towards the right end of the platform 1 through the roller one 20, the roller one 20 rotates and pushes the sliding shaft 14 to move rightwards relative to the sliding groove 13, the connecting rod 15 rotates towards one side of the connecting rod, which is close to the sliding shaft 14, and meanwhile drives the limiting block 16 to slide downwards for a certain distance; conversely, when the inner scissor arm 18 slides linearly in a reverse direction towards the left end of the platform 1 through the roller one 20, the connecting rod 15 reversely rotates towards one side of the connecting rod, which is far away from the sliding shaft 14, under the reset action of the torsion spring on the torsion spring shaft 28, and the limiting block 16 moves a certain distance upwards when the sliding shaft 14 moves leftwards relative to the sliding groove 13, so that the torsion spring shaft 28 is favorable for the sliding shaft 14 to always contact with the roller one 20, and the lifting linkage of the limiting block 16 and the platform 1 is realized.
Based on the above scheme, as in the second embodiment shown in fig. 2, 5 and 6, the torsion spring shaft 28 is changed into a common rotating shaft, and the elastic telescopic shaft 30 is used to replace the torsion spring, so that the restoring force of the sliding shaft 14 moving leftwards relative to the chute 13 can be further improved, the sliding shaft 14 is ensured to be always contacted with the roller one 20, and the lifting linkage of the limiting block 16 and the platform 1 is realized. Therefore, the two technical schemes can be selected according to actual requirements.
