Background technique

Permeable pavement bricks are a new type of highly permeable pavement material, which are made of certain graded aggregates, cement, special binders and water through special processes and special equipment. Compared with ordinary concrete pavement bricks, its biggest feature is its large water permeability coefficient;

When it rains, rainwater can seep into the ground through the pavement bricks in time, or be stored in the gaps of the pavement bricks, reducing road water accumulation. Concrete pavement permeable bricks can be widely used in the paving of courtyards, parks, squares, gardens, factory areas, parking lots, tree pits, greenhouses, pedestrian trails and light traffic highways. Permeable concrete pavement bricks can not only beautify the environment, but also prevent the loss of precious water resources, and have good social, environmental and ecological effects. The development and application of permeable concrete pavement bricks have received great attention and welcome from relevant national departments and all walks of life.

The hopper push plate 636 clamps the upper surface of the lower mold 22 during this process. , the upper surface of the material in the lower mold 22 can be scraped flat. After being separated from the lower mold 22, the hopper push plate 636 moves downward due to its own gravity, thereby completing the reset.

The linkage between the lower mold 22 and the third connecting rod 34 can ensure that the hopper assembly 63 is accurately opened when the feeding operation is required, thereby facilitating the feeding operation. After the feeding operation is completed, due to the slope design on the side of the lower mold 22 and the second spring 635 can be used in conjunction with the hopper assembly 63 to close the hopper assembly 63 in time, thereby ensuring that there is no waste of materials, saving a lot of material resources, and ensuring that the workbench is neat and clean. It also ensures that the bottom surface of the hopper assembly 63 will not move horizontally during the horizontal movement. It rubs against the material on the workbench, thereby extending the service life of the hopper assembly 63 and saving a large amount of material and equipment costs.

Working principle: During operation, when the hydraulic press drives the movable plate to move downward, it also drives the upper mold 21 to move downward, and is used in conjunction with the lower mold 22 to complete the pressing and forming operation. At the same time, it drives the sliding arm 31 to move downward, and then the sliding arm 31 The first toothed plate 33 is driven to slide vertically downward. The first toothed plate 33 can drive the first gear 34 meshed with the first toothed plate 33 to rotate, and then drive the power transmission shaft 35 to rotate, and then drive the worm 36 to rotate. The rotation of the worm 36 can The worm gear 41 is driven to rotate, and the rotation of the worm gear 41 can drive the connecting block 43 to rotate, and then the racket block 441 located on the connecting block 43 can vibrate the lower mold 22. Since the racket block 441 is rotationally connected with the connecting block 43, the racket block 441 can be guaranteed to be The tapping and vibration action of 441 on the lower mold 22 is relatively gentle, and a torsion spring 442 is provided at the rotating joint to ensure that the rotating racket 441 can be reset in time during the tapping and vibration operation.

When the hydraulic press moves upward, the second tooth plate 52 and the third tooth plate 53 mesh with the second gear 54 at the same time. After the pressing and forming operation is completed, the hydraulic press drives the moving plate to move upward, and then drives the connecting plate 51 to move upward. When the second tooth plate 52 When the toothed plate 52 starts to contact the third gear 651, it can drive the third gear 651 to rotate, and then drive the meshed third toothed plate 53 to move, and then the third toothed plate 53 drives the pull-down seat 55 to move downward, and then drives the pull-down plate 553 Move downward, thereby driving the lower mold 22 to move downward. Since the molded parts located in the lower mold 22 are held up by the bottom block 26, they will not move downward with the lower mold 22. The lower mold 22 is completely embedded in the mold groove 23. At this time, the hydraulic press is stopped under the control of the central control system, and the upper surface of the lower mold 22 is flush with the surface of the workbench, thereby completing the demoulding operation.

Subsequently, the raw materials pass through the material box 61 and enter the feeding pipe 62, and finally enter the inside of the hopper shell 631. Due to the obstruction of the telescopic plate 633 and the hopper push plate 636, the raw materials will not leak out of the hopper shell 631, and then pass through the electric push rod. 64 drives the hopper assembly 63 to move horizontally along the workbench to just above the lower mold 22 embedded in the mold slot 23, and during this process, the hopper push plate 636 pushes the formed and demoulded molded parts away from the top of the bottom block 26. Then, under the control of the central control system, the hydraulic press continues to move upward. As the second toothed plate 52 moves upward and separates from the second gear 54, the third toothed plate 53 is freed from the constraint. Under the action of the elastic potential energy of the first spring 552, it drives The pull-down seat 55 moves upward, thereby pushing the lower mold 22 to move upward. At this time, the upper surface of the lower mold 22 pushes the third telescopic rod 634 to move upward. When the third telescopic rod 634 moves upward, it drives the fourth toothed plate 655 to move upward. Then the meshed third gear 651 is driven to rotate, and then the third gear 651 drives the first sprocket 652 to rotate, and then the second sprocket 657 is driven to rotate through the transmission effect of the chain 653, and then the second sprocket 657 can drive the fourth gear 654 Rotate, the fourth gear 654 can drive the fourth tooth plate 655 to slide, and then drive the telescopic end of the telescopic plate 633 to slide. At this time, the material can fall down to the inside of the lower mold 22 along the gap between the telescopic plate 633 and the hopper frame 632 , complete the feeding process.

When the third telescopic rod 634 moves upward, it also drives the first buckle 6341 to move upward, which in turn drives the second buckle 6361 to move, and then drives the hopper push plate 636 to slide upward. At this time, the hydraulic press is still in the operating state, and then The moving plate is still moving upward, which in turn drives the sliding arm (31) to move, and at the same time drives the first connecting rod 32 to move upward, which in turn drives the second connecting rod 33 to move, and then pulls the third connecting rod 34 toward the side wall of the frame 1 Sliding, and then the first tooth plate 35 drives the meshed first gear 41 to rotate again during the return stroke, and then drives the connecting block 43 to rotate, and then drives the racket block 441 to vibrate the hopper shell 631.

After the feeding operation is completed, the electric push rod 64 is driven to shrink under the control of the central control system, and then the hopper assembly 63 is driven to return and reset. In the present invention, the side wall of the lower mold 22 is provided with a linear slope, and then the third expansion and contraction occurs during the return process. When the rod 634 moves along the slope, the elastic potential energy of the second spring 635 can drive the third telescopic rod 634 to press against the slope, and then the third telescopic rod 634 moving downward can drive the force transmission assembly 65 to operate, and finally The telescopic plate 633 can be extended outward, and before the hopper assembly 63 is separated from the lower mold 22, the telescopic plate 633 is closed and reset to prevent the internal material from leaking. The hopper push plate 636 clamps the upper surface of the lower mold 22 during this process. , the upper surface of the material in the lower mold 22 can be scraped flat. After being separated from the lower mold 22, the hopper push plate 636 moves downward due to its own gravity, thereby completing the reset.
