Description

Technical Field

[0001] This utility model relates to the technical field of ceramic powder making and fabrication equipment, and in particular to a belt fabrication system for wetting, powder making, and forming of building ceramics. Background Technology

[0002] In the current production field of architectural ceramics, both wet and dry production methods utilize a feeding hopper to distribute the material onto a grid. Compared to wet production, which relies on water droplets to bind the fine powder, wet powder production is more common due to its better powder flowability. However, dry powder production suffers from poor flowability because the powder is easily peeled off and clumps together, often resulting in uneven distribution when using a traditional feeding hopper. Wet powder production, which only wets the fine powder without creating particles, suffers from even worse flowability. While wet powder production has effectively solved the insurmountable production defects of dry powder production, the uneven distribution caused by powder adhesion and poor flowability remains a bottleneck. Finding a method to ensure uniform grid filling and material distribution is key to the success of wet powder production.

[0003] Therefore, this utility model provides a building ceramic wetting powder forming belt fabric distribution system to solve the problems existing in the prior art. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-3 As shown, this embodiment provides a building ceramics wetting powder forming belt feeding system, including a molding press 1, a forming mold 2 installed inside the molding press 1, a belt feeding cart 7 located at the rear of the molding press 1, a cleaning component 3 for cleaning residual powder between the belt feeding cart 7 and the molding press 1, a grid 12 for conveying powder to the forming mold 2 installed on the belt feeding cart 7, a feeding belt 15 installed on the belt feeding cart 7, a collecting cone located above the rear side of the belt feeding cart 7 away from the grid 12, the bottom of the collecting cone inserted into the discharge hopper, the discharge hopper located above the belt feeding cart 7, an anti-sticking roller screen 8 located above the collecting cone for screening powder, a guide belt 9 for conveying powder located above the anti-sticking roller screen 8, and a press hopper 10 located above the guide belt 9.

[0020] The anti-sticking roller screen 8 differs from traditional roller screens in that the screen mesh is coated with a Teflon anti-sticking coating, the bottom of the cylinder is equipped with a blocking net, and the screen cylinder is filled with hedgehog balls for crushing granular powders. The collecting cone is made of anti-sticking high-density PE board to prevent sticking, and the cone opening is designed to be rectangular. It is inserted into the feed hopper of the belt conveyor 7 to feed material to the lower hopper. Instead of using a traditional hopper to fill the grid 12, a conveyor belt 15 is used to distribute the powder. The required filling depth is evenly distributed on the conveyor belt 15, allowing the grid 12 to move downwards until it contacts the surface of the conveyor belt 15. This allows the powder on the conveyor belt 15 to fill the grid 12. As the conveyor belt 15 moves towards the molding press 1, a hopper above it continuously discharges powder onto the conveyor belt 15. The hopper's vertical movement is adjustable to ensure sufficient powder thickness on the conveyor belt 15. The hopper is made of high-density PE board to prevent powder from sticking to the walls. The hopper is also fitted over a collecting cone to reduce the impact of the gate churning process on the powder. A non-stick roller screen 8 is installed above the collecting cone to separate the powder, and a press hopper 10 and a guide belt 9 are used to ensure continuous powder supply and maintain operational continuity. The height of the hopper is adjustable to accurately control the amount of powder distributed for different products. This invention solves the problems of low bulk density, high compression ratio, and large required feeding depth in wet powder preparation. By allowing the material to be fed naturally from the hopper as the feeding belt 15 moves forward, it solves the problem of the traditional feeding hopper requiring the opening and closing of the gate plate each time it feeds, which causes some powder to be squeezed and agglomerated. It fundamentally solves the problem of difficult forming of wet powder preparation and dry powder preparation in the molding press 1.

[0021] Furthermore, the molded press 1 is currently the most widely used in the building ceramics industry. The molded press 1 uses a grid 12 to distribute the material into the mold cavity. The upper punch moves down and up with the upper mold core, from the first light pressing to pulverize, vent, and shape the material in the mold cavity, to the second and third pressing to form a blank. Then, the ejector cylinder pushes the brick blank out through the lower mold core. At the same time, as the grid 12 moves forward, a pusher plate pushes the brick blank out of the press.

[0022] Furthermore, the forming mold 2 is a device for turning powder into brick blanks. The forming mold 2 consists of a bottom frame, a middle frame, support columns, an upper mold core, and a lower mold core. The specific operation is as follows: First, the ejector cylinder of the molding press 1 pushes the lower mold core to the same level as the middle frame. Then, the grid 12, along with the material distribution belt 15, moves the powder taken by the grid towards the forming area of ​​the press, stopping above the mold cavity. Then, the lower mold core of the forming mold 2 falls into the mold cavity to fill the powder. The grid 12 is lifted, and the front scraper of the grid 12 moves backward close to the surface of the middle frame to flatten the powder in the mold cavity. Finally, the upper punch of the molding press 1, along with the upper mold core, presses the powder into blanks three times. The upper mold core, driven by the ejector cylinder, pushes the brick blank out of the mold cavity. At the same time, with the next material distribution of the grid 12, the brick blank is pushed out of the mold middle frame of the press, thus forming a continuous forming cycle.

[0023] Furthermore, the press hopper 10 is a necessary configuration for stable press production. It has a square design, a tapered rectangular discharge port, and a gap of about 20mm between it and the guide belt 9. It is fixed with high-density PE board and steel hooks.

[0024] The design was further optimized. The belt conveyor fabric carrier 7 includes a frame 14, with support legs fixed to the four corners of the bottom surface of the frame 14.

[0025] Further optimization of the design involves symmetrically installing guide rails on frame 14, located on both sides of the fabric belt 15. A movable frame 16 is connected between the guide rails, and the grille 12 is located within the movable frame 16. A lifting structure 17 is fixedly installed on the movable frame 16, controlling the lifting of the grille 12. The grille 12 is raised when it reaches above the molding die 2 and lowered when it returns to the filling position. In use, first, adjust the material feeding height of the hopper according to the mold cavity depth; then, start the fabric belt 15, moving it towards the molding press 1, evenly distributing powder onto the fabric belt 15. The powder width should exceed the width of the grille 12 by approximately 10mm on each side, and the powder length on the fabric belt 15 should exceed the longitudinal length of two mold cavities, with the top extending less than 10mm beyond the position of the grille 12. After the powder on the fabric belt 15 reaches the lower end of the grille 12, the lifting structure 17 is activated, moving the grille 12 downwards onto the fabric belt 15. The powder is positioned within the grid 12; then the guide rail drives the moving frame 16 to move towards the molding press 1, stopping above the mold cavity. As the lower mold core falls, the powder from the grid 12 fills the mold cavity, completing the material distribution. Subsequently, the grid 12 rises back to the fixed position, and with the return movement, the scraper returns to the material cart, leveling the powder in the mold cavity, ensuring uniform powder distribution and creating conditions for pressing and forming. After the grid 12 returns to its original position, the cleaning brush 11 moves to clean the powder on the connecting plate 4, thus completing one material distribution process. The repeated material distribution creates a continuous production effect.

[0026] Furthermore, the lifting structure can be any type of hydraulic lifting, sleeve cylinder lifting, screw lifting, etc., the purpose of which is to complete the action of lifting or lowering the grid 12 to fill the powder.

[0027] Further optimization involves installing a connecting plate 4 between the fabric belt 15 and the molding die 2. The connecting plate 4 is installed between the horizontal position of the frame of the molding die 2 and the horizontal position of the fabric belt 15 on the belt-driven fabric cart 7. Its function is that because the arc formed by the rollers at the end of the fabric belt 15 causes a large amount of material to fall as the grid 12 moves forward, it is impossible for the grid 12 to carry the powder to the top of the mold cavity. The connecting plate 4 must be installed to complete the powder pushing by the grid 12. The connecting plate 4 is tightly connected to the mold frame, with a 2mm-3mm gap between it and the arc tangent point of the fabric belt 15, requiring all three to be on the same horizontal plane.

[0028] The cleaning component 3 is further optimized by including a transmission frame 13 fixedly connected to the frame 14, and a cleaning brush 11 fixedly connected to the transmission frame 13. The cleaning brush 11 is used to clean the powder residue on the connecting plate 4. After each cloth circulation cycle of the grid 12 and its return to the initial position, the cleaning brush 11 cleans the loose powder off the connecting plate 4.

[0029] The design is further optimized by installing a hopper 5 below the connecting plate 4. The hopper 5 is used to collect the powder scraped off by the cleaning brush 11. A steep-angle conveyor belt 6 is installed below the hopper 5, with its top positioned above the collecting cone. The hopper 6 collects the scraped material and recycles it to the anti-sticking roller screen 8 for further screening and reuse. The hopper 5 collects the residual material from the push plate material during the return of the grid 12, the residual material on the connecting plate 4 cleaned by the cleaning component 3, and the residual material outside the frame of the grid 12 after it moves down on the cloth conveyor belt 15. The steep-angle conveyor belt 6 lifts the residual material collected in the hopper 5 to the collecting cone opening, mixes it with the powder, and reuses it, thereby achieving full utilization of the powder and clean production.

[0030] The design was further optimized by using an anti-stick belt for the fabric conveyor belt 15 and coating the grating 12 with a Teflon anti-stick layer. This Teflon anti-stick layer on the grating 12 solves the problems of powder adhesion and powder flakes and corner sticking caused by friction during the return stroke of the traditional grating 12.
