Detailed implementation manners

[0021] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. For the convenience of description, words such as "upper", "lower", "left", and "right" hereinafter only indicate the same directions as the upper, lower, left, and right directions of the accompanying drawings themselves, and do not limit the structure.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments in the following disclosure.

[0023] Embodiment, as Figures 1 to 6 As shown, the static press for block production provided by the present invention includes a machine body 1, a hydraulic cylinder 2 is arranged on the machine body 1, an upper die 3 is arranged at the bottom of the hydraulic cylinder 2, a lower die 4 is arranged below the upper die 3, a frame 5 is arranged on one side of the machine body 1, a blanking device 6 is arranged on the frame 5, the blanking device 6 includes a material hopper 61, a blanking switch mechanism 62 is arranged on one side of the material hopper 61, and a feeding device 7 is movably arranged below the material hopper 61. Among them, the hydraulic cylinder 2 controls the mold closing action and demolding action of the upper die 3 and the lower die 4. On this basis, telescopic mechanisms 8 are arranged at both side corner positions of the lower die 4, the telescopic mechanisms 8 are connected to the top of the machine body 1 and their telescopic ends face downward. The telescopic mechanisms 8 can be used to adjust the height of the lower die 4 in real time. Especially, the lower die 4 is appropriately raised during the demolding process, so that the height position of the block and the lower die 4 is staggered to achieve demolding; on the other hand, the telescopic mechanisms 8 can control the height of the lower die 4 to be consistent with the pushing level of the feeding device 7 to achieve effective filling of the sand material.

[0024] Further, a scraping mechanism 9 is provided between the lower die 4 and the upper die 3 of the present utility model. The scraping mechanism 9 is connected to the feeding device 7. The feeding device 7 includes a receiving hopper 71 for movably connecting to the material storage hopper 61. A material turning mechanism 72 is provided inside the receiving hopper 71. A transmission mechanism 73 is provided on the power input side of the material turning mechanism 72. A reduction motor 74 is provided at the power input end of the transmission mechanism 73. A rolling support device 10 that is slidably engaged with the feeding device 7 is provided on the side of the feeding device 7 facing away from the machine body 1. An upper feeding driving cylinder 11 connected to the receiving hopper 71 is provided inside the rolling support device 10. The diameter of the material storage hopper 61 gradually decreases from top to bottom. The blanking switch mechanism 62 includes a mounting seat 621 provided on the side of the material storage hopper 61 facing away from the machine body 1. A K-series reduction motor 622 is provided on the mounting seat 621. A connecting rod assembly 623 is provided on the power output side of the K-series reduction motor 622. An arc-shaped valve plate 624 is provided at the end of the connecting rod assembly 623. The bottom opening of the material storage hopper 61 opposite to the valve plate 624 is an arc opening. Rotating plates 625 hinged to the material storage hopper 61 are provided at both ends of the valve plate 624.

[0025] Specifically, the upper feeding driving cylinder 11 can simultaneously drive the receiving hopper 71 and the scraping mechanism 9 to perform linear reciprocating motion in the horizontal direction. Especially after the sand material in the receiving hopper 71 is filled into the lower die 4, if the receiving hopper 71 and the scraping mechanism 9 are pulled back by the upper feeding driving cylinder 11, the scraping surface of the scraping mechanism 9 passes through the surface of the lower die 4 to scrape and level the sand material, which is beneficial to improving the effect of mold closing and demolding of the upper and lower dies 4 of the static press, and further improving the forming quality of the building blocks. At the same time, during the telescopic process of the upper feeding driving cylinder 11, the moving surfaces of the receiving hopper 71 and the scraping mechanism 9 are rollingly supported by the rolling support device 10, which can ensure the moving efficiency of the receiving hopper 71 and the scraping mechanism 9. On this basis, the opening and closing of the bottom opening of the material storage hopper 61 is controlled by the blanking switch mechanism 62. More specifically, the K-series reduction motor 622 is used to control the connecting rod assembly 623. The connecting rod assembly 623 transmits power to the valve plate 624. The valve plate 624 can swing to open and close the material storage hopper 61 under the hinge action of the rotating plate 625 and the material storage hopper 61. Moreover, the size of the bottom opening of the material storage hopper 61 is designed appropriately, and the immediate response effect of the bottom opening switch is good, which can improve the feeding efficiency of the device.

[0026] To improve the practicality of the scraping mechanism 9, the scraping mechanism 9 provided by the present utility model includes a return frame 91, and a plurality of scraping plates 92 are provided inside the return frame 91. The translation surface of the return frame 91 can cover the sand material filling surface of the lower die 4, and the sand material is scraped and sent from the building block die holes of the lower die 4 by the scraping plates 92, ensuring that the building block die holes after mold closing have relatively uniform pressure, which is beneficial to obtaining building block blanks that meet the production requirements.

[0027] In order to improve the rolling support performance of the rolling support device 10 for the feeding device 7, the rolling support device 10 provided by the present utility model includes two oppositely distributed channel plates 101. A plurality of cross plates 102 connecting the two channel plates 101 are arranged on the top of the channel plates 101. Two rows of support bearings 103 distributed vertically are arranged on the inner side of the channel plates 101. A support shaft 104 connected to the channel plates 101 is arranged at the center of the support bearings 103. The space between the upper and lower two rows of the support bearings 103 is used to cooperate with the feeding device 7. In this way, both sides of the feeding device 7 can be supported by the support bearings 103, and the support bearings 103 generate rolling actions driven by the moving friction force of the feeding device 7, thereby ensuring the moving efficiency of the feeding device 7 after being driven by the feeding driving cylinder 11.

[0028] Furthermore, the feeding device 7 provided by the present utility model further includes a sliding plate 75 that cooperates with the support bearings 103. The sliding plate 75 is connected to the material receiving hopper 71 and the scraping mechanism 9. Therefore, when the feeding driving cylinder 11 drives the feeding device 7, it can drive the scraping mechanism 9 to perform a synchronous translation action with the feeding device 7.

[0029] In order to improve the transmission performance of the connecting rod assembly 623 for the valve plate 624, the connecting rod assembly 623 provided by the present utility model includes a rocker arm 6231 connected to the transmission end of the reduction motor 74. A planar moving rod 6232 rotatably connected to the end of the rocker arm 6231 is arranged at the end of the rocker arm 6231. A connecting head 6233 rotatably connected to the bottom of the planar moving rod 6232 is arranged at the bottom of the planar moving rod 6232. The connecting head 6233 is connected to the valve plate 624. The K series reduction motor 622 is used to drive the rocker arm 6231 to swing. The rocker arm 6231 drives the planar moving rod 6232 to perform a planar motion, thereby driving the connecting head 6233 and the valve plate 624 to move. The valve plate 624 opens and closes the bottom opening of the material storage hopper 61 under the hinge action of the rotating plate 625.

[0030] In order to improve the feeding efficiency into the lower die 4, the turning mechanism 72 of the present utility model includes a plurality of rotating shafts, and a plurality of plow blade plates 721 are arranged on the rotating shafts; at the same time, the transmission mechanism 73 includes gears arranged at the ends of each rotating shaft. The gears can be synchronously driven by a chain or synchronously driven by a triangular gear belt. The power of the transmission mechanism 73 comes from the reduction motor 74 and the gearbox, thereby realizing the rotational drive of the plow blade plates 721. If the plow blade plates 721 move to the position where the lower die 4 is located along with the feeding device 7 in a continuous stirring manner, the sand material can be reasonably filled into the block die holes, thereby ensuring the compaction density and hardness of the blocks.

[0031] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
