[0004] In the above-mentioned patent disclosure, the press mainly seals the bottom opening of the movable seat through the base, pushes the material in the movable seat into the lower die through an external driving force, and then drives the punch through an external force to press the mixed material in the lower die;

[0005] Although the movable seat and the base are fitted together in the above patent, there is still a small gap between the movable seat and the base. During the process of the movable seat pushing the material, the mixed material in the movable seat flows out of the movable seat and accumulates on the base. After the movable seat has been feeding the material for a long time, the accumulation of the mixed material on the base affects the movement of the movable seat. Therefore, it is necessary to provide a press for preparing foamed ceramics to solve the above problem.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] like Figure 1-Figure 2 As shown, the present application provides a press for preparing foamed ceramics, including a press mechanism 3, which is used to press and shape a mixture;

[0024] The pressure mechanism 3 includes a base 33, and a pressure head 31 slidably mounted on the top of the base 33, and a second cylinder (not shown in the figure) is fixed on the top of the base 33, the output end of the second cylinder is connected to the pressure head 31, and the pressure head 31 is driven to move up and down under the action of the second cylinder;

[0025] A pedestal 34 is provided on the base 33 near the bottom of the base 33 , and a mold 32 is fixedly mounted on the pedestal 34 , and the mold 32 is located directly below the pressing head 31 ;

[0026] When preparing foamed ceramics, a mixture is filled into the mold 32, and under the drive of the second cylinder, the pressing head 31 applies pressure to the mold 32 to press the mixture into shape, thereby producing a foamed ceramic product;

[0027] A feeding mechanism 1 is provided on the side of the pressure mechanism 3, and the feeding mechanism 1 is used to transport the mixed material. The feeding mechanism 1 includes a frame 11, and a feed hopper 12 installed on the top of the frame 11, and a conveyor belt 13 is also installed on the frame 11. The conveyor belt 13 is a belt conveying device in the prior art. The conveyor belt 13 is arranged below the feed hopper 12, and the feed hopper 12 is used to transport the mixed material to the conveyor belt 13;

[0028] like Figure 2-Figure 3 As shown, a feeding mechanism 2 is provided on the side of the pedestal 34 near the discharge end of the conveyor belt 13, and a guide hopper 14 is provided at the discharge end of the conveyor belt 13, the guide hopper 14 is used to guide the mixed material transported by the conveyor belt 13 into the feeding mechanism 2, and the feeding mechanism 2 feeds the mixed material into the mold 32;

[0029] The feeding mechanism 2 includes a base 24 fixedly mounted on a pedestal 34, and a hopper 22 disposed on the base 24. The hopper 22 is through-set, and a groove (not shown in the figure) is provided on the base 24 to form a sealing surface 241. The bottom opening of the hopper 22 abuts against the sealing surface 241, and the sealing surface 241 is flush with the top surface of the mold 32.

[0030] At the same time, the feeding mechanism 2 also includes two groups of guide rods 23 and a first cylinder 21. The two groups of guide rods 23 are respectively installed on both sides of the pedestal 34, and a cross bar 221 is fixed on the side of the hopper 22 away from the bottom platform 24, and rollers 222 are installed on both sides of the cross bar 221. The first cylinder 21 is installed on the frame 11, and the output end of the first cylinder 21 is fixedly connected to the cross bar 221. Under the action of the first cylinder 21 and through the cooperation of the rollers 222 and the guide rods 23, the hopper 22 is driven to move on the sealing table 241 and approach or move away from the opening direction of the mold 32.

[0031] When it is necessary to add material to the mold 32, first add the mixed material to the feed hopper 12, and convey the mixed material to the guide hopper 14 through the conveyor belt 13. Under the action of the guide hopper 14, the mixed material is introduced into the receiving hopper 22. After the material in the receiving hopper 22 reaches the required amount, the conveyor belt 13 stops conveying, and the first cylinder 21 drives the receiving hopper 22 to approach the mold 32. When the bottom opening of the receiving hopper 22 corresponds to the opening of the mold 32, the mixed material in the receiving hopper 22 flows into the mold 32, thereby sending the mixed material in the receiving hopper 22 into the mold 32, and then completing the feeding operation of the mold 32;

[0032] An isolation plate 25 adapted to the bottom platform 24 is also installed on the bottom platform 24. The isolation plate 25 is arranged with an inclined surface. A cavity 27 is formed between the isolation plate 25 and the inner wall of the groove. A plurality of groups of holes are provided on the isolation plate 25, thereby connecting the cavity 27 with the bottom platform 24.

[0033] At least two groups of suction heads 26 are installed on the outer side of the base 24, and the suction heads 26 lead to the cavity 27, and the suction heads 26 are connected to a pump (not shown in the figure);

[0034] At the same time, when the hopper 22 moves toward the mold 32, one side of the hopper 22 is moved by the thrust of the cylinder, and the hopper 22 and the sealing table 241 conflict with each other, so that a small gap is easily generated between the bottom of the hopper 22 and the sealing table 241, causing the mixed material to flow out of the hopper 22 and accumulate on the sealing table 241.

[0035] When materials are piled up on the bottom platform 24, suction is formed in the cavity 27 through the pump and the cooperation of the suction head 26, and the holes on the isolation plate 25 cooperate to clean the sealing table 241 and the mixed materials in the cavity 27;

[0036] To summarize, through the action of the isolation plate 25 on the base 24, the mixed material overflowing from the hopper 22 on the sealing surface 241 is stored in the cavity 27, and through the cooperation of the pump and the suction head 26, the sealing surface 241 and the cavity 27 are cleaned, and the accumulation of materials on the sealing surface 241 is prevented from affecting the movement of the hopper 22, thereby solving the problem of the accumulation of mixed materials affecting the feeding.

[0037] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
