A baffle 84 is fixed on one side of the pressure plate 83, and the baffle 84 is arranged obliquely upwards along the direction far away from the pressure plate 83.
The specific implementation process is as follows:
and the pug is put into the conveying channel 2 from the feed inlet, and then the driving motor is started, so that the rotation of the rotating shaft 6 is realized through the transmission of the driving gear and the reduction gear. When the conveying section rotates, the conveying section can drive the pug to be conveyed rightwards, and in the process, the pug can be mixed under the action of the conveying blades 211 and the mixing rod 212, so that the pores in the pug are reduced, and the compactness of the prepared bottom plate is increased.
When the pug is transmitted to the right end, the pug falls into the forming frame through the opening at the right end of the transmission channel 2, in the process, the forward and reverse rotating motor 7 is started, the rotating shaft 6 is driven to rotate forward through the transmission of the rotating gear 71 and the driven gear 64, the rotation of the stopping ring 3 is realized through the meshing of the driving gear 61 and the driven inner gear ring 32, and therefore the whole forming frame rotates. Because the in-process of pug conveying, the shaping frame takes place to rotate, therefore the pug can be even falls to in the shaping frame.
After a certain amount of pug is accumulated in the forming frame, the pressing rod 81 is rotated, so that the pressing rod 81 drives the pressing plate 83 to move downwards, and the thickness of the prepared bottom plate can be set by setting the distance of downward movement of the pressing plate 83. The in-process that the clamp plate 83 moved down can be with the mud material compaction downwards, can be at the pivoted in-process of shaping frame simultaneously for relative movement takes place between mud material and the clamp plate 83, thereby guarantees that the surface is smooth.
After the bottom plate is formed, the pressing rod 81 is rotated reversely, so that the pressing plate 83 moves upwards to be separated from the forming frame. In the process, the pull rod can drive the liquid storage ring 4 to move upwards, so that the liquid inlet hole is positioned at the bottom, and the release agent is conveniently added into the forming frame.
After the release agent enters the forming frame, the forward and reverse rotating motor 7 drives the rotating shaft 6 to rotate reversely, and under the matching of the one-way bearing 63 and the thread block 62, the rotating shaft 6 rotates and moves upwards, so that the base 5 moves upwards and rotates, the release agent can play a role in lubrication, and the formed bottom plate can be conveniently demoulded; in the process, the torsion spring stores energy.
After the demolding is finished, the forward and reverse rotation motor 7 is closed, the thread block 62 is driven to rotate reversely under the action of the torsion spring, so that the thread block 62 and the rotating shaft 6 move downwards and reset along with the thread block until the base 5 abuts against the limiting block 33, and the next bottom plate molding is carried out.
It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention, and these changes and modifications should not be construed as affecting the performance of the invention and its practical application.
