The flip reset mechanism further comprises a fixing piece 21. The double slide bar 19 is fixed to the upper portion of the bracket 18 by the fixing member 21 and corresponds to a position above the casting plate 14.
The following describes a complete working process of the granulator:
first, the center power unit 2 and the water pump are turned on. The central power unit 2 drives the cooling mechanism and the casting mechanism to synchronously perform circular motion along the track on the base 1, and the water pump supplies cooling water to the water tank 5 of the cooling mechanism. In the process of circular motion of the casting forming mechanism, molten iron in a ladle 28 enters the pouring hopper 4 through the pouring groove 27, and then molten iron in the pouring hopper 4 is continuously poured into the ball socket 16 on each casting template 14 of the casting forming mechanism, and cold water in the cooling water channel 17 in the casting template 14 cools the molten iron in the ball socket 16, so that the molten iron is formed into a granular product matched with the shape of the ball socket 16. After the granular product in the ball socket 16 is formed, the roller 20 at the end of the roller reaches the opening of the double slide bar 19 along with the circular movement of the casting plate 14, and under the continuous circular movement of the casting plate 14, the roller 20 enters into and moves along the sliding groove inside the double slide bar 19. Since the double slide bar 19 is bent and extended upward toward the outer side of the water tank 5, then is bent and extended downward toward the outer side of the water tank 5, and finally is bent and extended upward toward the inner side of the water tank 5, then is bent and extended downward toward the inner side of the water tank 5, and then is extended to the position where molten iron is ready to be cast in the circular motion track of the casting plate 14, the casting plate 14 can perform corresponding overturning action under the guidance of the double slide bar 19 (slide groove): that is, the end of the casting plate 14 near the roller 20 is turned upwards relative to the water tank 5 (the included angle between the casting plate 14 and the water tank 5 is gradually opened) to release the formed granular product, and then turned downwards relative to the water tank 5 to turn and reset (the included angle between the casting plate 14 and the water tank 5 is gradually closed) to prepare the next casting molten iron. Under the action of the double slide bars 19, the demolding of the granular product on the casting plate 14 and the resetting after the demolding of the casting plate 14 are completed. When the casting template 14 performs the overturning actions of demoulding the granular product and resetting, the water inlet rotary joint 6 and the water outlet rotary joint 7 can ensure that the cooling water channel in the casting template 14 can be normally cooled by water, and the overturning actions of automatic demoulding and resetting of the casting template 14 are not influenced, so that the problem of automatic demoulding of a casting forming mechanism under the condition of water receiving and placing through a pipeline is solved, the production environment is improved, and the production cost is reduced. At the end of the mould plate 14 close to the roller 20, the mould plate is turned upwards relative to the water tank 5 to a position where the granular product is automatically demoulded (after the included angle between the mould plate 14 and the water tank 5 is opened to a certain extent), the granular product is demoulded from the mould plate 14 and enters the hopper 23 through the chute 22, and finally the granular product is collected in the hopper 23. The die plate 14 after demoulding is turned downwards relative to the water tank 5 under the guide of the double slide bars 19 until the double slide bars 19 are removed and reset to be horizontal, so as to prepare for the next casting and forming. To this end, a working cycle is completed.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
