Description

Technical Field

[0001] This invention relates to the field of ceramic tile processing equipment, and more specifically, to an apparatus and method for improving the quality of pressed ceramic tile blanks. Background Technology

[0002] Tiles are typically formed by pressing ceramic powder into shape within a mold cavity. The ceramic powder used is spherical granules produced by a spray drying tower, which have a high air content. When processing with traditional molds, the air contained within the ceramic powder rapidly accumulates under immense pressure during the pressing process, forming air clusters. As the pressure increases, these air clusters are further compressed. When the pressure exceeds the cohesive force between the materials, the air clusters disrupt the cohesion between the materials, affecting the density of the tile blank. This reduces the forming strength and quality of the tile blank, ultimately impacting the overall product quality, which requires improvement. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, the technical problem to be solved by this invention is to propose a device and method for improving the quality of pressed ceramic tiles. This device provides an outlet for high-pressure air masses during the pressing process and recovers powder mixed in the airflow, reducing waste. It also cleans the exhaust holes through backflushing, preventing blockages from affecting subsequent exhaust operations.

Detailed Implementation

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 , Figure 2As shown in the figure, a specific embodiment of the present invention discloses a device for improving the quality of pressed ceramic tile blanks, including an upper mold core 100, the bottom surface of the upper mold core 100 being provided with uniformly arranged exhaust holes 110, the exhaust holes 110 being connected to an extraction pipe 120 and an air supply pipe 130; an extraction system 200, connected to the extraction pipe 120, for extracting the gas entering the upper mold core during the pressing process; and a backflushing system 300, connected to the air supply pipe 130, for clearing blockages in the exhaust holes;

[0036] The aforementioned device for improving the quality of pressed ceramic tile blanks utilizes vent holes and extraction pipes as channels for the discharge of high-pressure air masses during the pressing process; it actively extracts gas entering the upper mold core during the pressing process through an extraction system to ensure venting effect and prevent high-pressure gas generated during pressing from affecting product quality; and it recovers powder mixed in the airflow to reduce waste.

[0037] The backflush system can clean the exhaust ports by backflushing, preventing blockages from affecting subsequent exhaust operations and maintaining smooth operation.

[0038] It should be noted that the circuits of both the suction system and the back-blowing system are connected to the control box of the molding device, so that the suction and air supply actions are coordinated with the pressing action; suction is performed during the pressing process to allow the high-pressure gas to be discharged; after pressing and molding, after the upper mold core is separated from the brick blank, the exhaust hole is cleared by back-blowing to achieve overall coordination.

[0039] Furthermore, such as Figure 2 As shown, the upper mold core 100 includes a pressure plate 140, with vent holes evenly arrayed on the bottom surface of the pressure plate; the pressure plate 140 is provided with multiple confluence holes 150 penetrating two opposite sidewalls, and the confluence holes 150 are connected to multiple vent holes 110 in the same row; an air extraction pipe 120 and an air supply pipe 130 are respectively provided on both sides of the pressure plate 140, the air extraction pipe 120 is connected to one end of the confluence hole 150 through multiple first unions 160, and the air supply pipe 130 is connected to the confluence hole 150 through multiple second unions 170. The other end is connected; the suction pipe is connected to the air inlet of the suction system through the first flexible hose; the air supply pipe is connected to the air outlet of the backflush system through the second flexible hose; the modular structure facilitates the processing and production of each structural component and makes it easy to disassemble and replace parts; the exhaust port and the manifold are arranged in the above manner, which on the one hand expands the suction range and improves the suction effect; on the other hand, it is easy to process, and can be completed by drilling, which can ensure the conductivity and airtightness of the corresponding air passages;

[0040] More specifically, the end of the vent hole is provided with a groove, and a plug is fixedly installed in the groove. The plug has micro-holes, which can further facilitate the processing of the vent hole on the base plate. The diameter of the hole can be changed by the plug installed later, so that the diameter of the micro-hole is 1-1.5mm, which can not only achieve effective venting, but also prevent a large amount of powder from being discharged.

[0041] Furthermore, the backflushing system 300 includes at least an air compressor 310, which delivers compressed air to the upper mold core via an air supply pipe to backflush and clear blockages in the exhaust port. More specifically, the backflushing system includes an air compressor, an air tank, a first precision filter, a dryer, and a second precision filter connected in sequence. The output port of the second precision filter is connected to a first solenoid valve, which is connected to a second flexible hose, forming a complete air compression system. This system compresses, filters, and dries the air, ensuring that the discharged gas has sufficient pressure to clear blockages in the exhaust port. The dried gas effectively prevents moisture from being mixed into the raw material, avoiding material clumping and further preventing blockages in the exhaust port. It should be noted that the above-mentioned air compression system is a relatively common combination, and the equipment used can be purchased and used commercially, so details will not be elaborated further.

[0042] Furthermore, such as Figure 1 , Figure 3 , Figure 4 As shown, the suction system 200 includes a filter 210 and a fan 220 installed on the filter 210. The air inlet of the filter is connected to the end of the first hose, and the fan is installed at the air outlet of the filter. By starting the fan, a negative pressure is formed, which also creates a negative pressure effect at the upper mold core, thereby achieving the suction of high-pressure gas during pressing. The filter 210 includes a hopper 211 and a filter device 212 installed inside the hopper 211. The filter device has a self-cleaning function, which can easily separate the powder mixed in the airflow and effectively clean and prevent clogging of the filter components, maintain smooth airflow, and thus maintain the negative pressure suction effect.

[0043] Furthermore, such as Figures 5 to 8As shown, the filtration device 212 includes a support plate 400, a filter cartridge 500, and a cleaning mechanism 600. The support plate 400 is installed inside the hopper 211, dividing the hopper 211 into a first chamber 213 and a second chamber 214. The first chamber is located below the second chamber. The bottom of the first chamber has a bucket-shaped structure, and a discharge port is provided at the converging and narrowing point. A switch valve is installed at the discharge port. The air outlet of the filter is located on the side wall of the second chamber. The air inlet of the filter is located on the side wall of the first chamber. The support plate 400 has a plurality of first perforations 410 arranged in a circular array around the center. A first pair of connecting pipes 420 is fixedly provided on the outer side of the bottom end of the first perforation 410, and the filter cartridge 500 is installed on the first pair of connecting pipes 420; the airflow entering the first chamber enters the second chamber after passing through the filter cartridge; the cleaning mechanism is used to clean the filter cartridge, so that the dust adhering to the filter cartridge falls off; the filter device is assembled from multiple parts and is a detachable structure, which facilitates the processing and production of each structural component and the overall assembly; among them, the use of the filter cartridge as the filter component is convenient for disassembly and assembly, and has appropriate structural strength, which facilitates the cleaning operation of the cleaning mechanism.

[0044] Furthermore, the cleaning mechanism 600 includes a bracket 610, a motor 620, and multiple brush kits 630. The bracket 610 is installed on the bottom surface of the support plate 400, and the bracket 610 is provided with multiple second through holes 611 for the filter cartridge to pass through. A turntable bearing 640 is installed on the outer side of the bottom end of the second through hole 611, and the top of the brush kit 630 is installed on the turntable bearing 640 by screws. The brush kit 630 is fitted onto the outer side of the filter cartridge 500. The motor is used to drive the brush kit to rotate and clean the outer wall of the filter cartridge. The whole is an assembled structure, which can facilitate the disassembly and replacement of each structural component. The brush kit is installed through the turntable bearing, which provides a better rotation base. The brush kit is surrounded on the outer side of the filter cartridge, and can effectively scrape and clean the outer wall of the filter cartridge during the rotation of the brush kit.

[0045] Furthermore, such as Figure 9 As shown, the brush assembly 630 includes a first support ring 631, a second support ring 632, and multiple brush rollers 633. The top end of the brush roller 633 is fixedly mounted on the bottom surface of the first support ring 631 by screws, and the bottom end of the brush roller 633 is fixedly mounted on the top surface of the second support ring 632 by screws. The multiple brush rollers are arranged in a circumferential array around the axis of the first support ring to form a cylindrical structure. The ends of the bristles of any two adjacent brush rollers abut against each other. This structural design can form a cylindrical barrier through multiple brush rollers, and use dense bristles to initially intercept dust, which can reduce the filtration load on the filter cartridge. Furthermore, when the brush assembly rotates, the bristles of the brush rollers contact and collide with the filter cartridge, which can not only clean the filter cartridge, but also shake off the dust adhering to the bristles, thereby achieving effective cleaning.

[0046] The first support ring 631 is mounted on the bottom surface of the turntable bearing 640 by screws, and the outer wall of the first support ring is provided with teeth; the motor is mounted on the top of the hopper by screws, and the output shaft of the motor 620 is connected to the transmission shaft 650. The transmission shaft is rotatably mounted between the top surface of the hopper and the bracket through the bearing. The bottom end of the transmission shaft 650 is equipped with a gear plate 660, which meshes with all the first support rings 631 for transmission; the motor drives all the brush kits to rotate, which simplifies the structure and reduces the structure and operating costs.

[0047] Furthermore, a bracket 670 is mounted on the bottom surface of the bracket 610 by screws. The bracket 670 is provided with multiple scrapers 671 arranged in a circumferential array. The position of the scrapers 671 corresponds to the position of the brush kit 630. One side of the scraper is in contact with the bristles of the brush roller. This design can use the fixed scraper to block the bristles during the rotation process, which is equivalent to using the scraper to further agitate the bristles, and can better shake off the powder adhering to them.

[0048] Furthermore, an air bag 230 is installed on the outer wall of the second chamber 214. The input end of the air bag is connected to the air outlet of the backflushing system through a third hose, and the output end of the air bag is connected to the second chamber. The first solenoid valve is a three-way valve structure, one of which is connected to the third hose. Using this structure, high-pressure gas can be used to backflush the filter cartridge, further enhancing the cleaning and anti-clogging effect.

[0049] Furthermore, the top surface of the support plate 400 is provided with a groove 430, which is circular in shape; a baffle 680 is fixedly provided on the drive shaft 650, the shape of the baffle 680 is adapted to the shape of the groove 430, and the bottom surface of the baffle slides against the bottom of the groove; the baffle 680 is provided with a plurality of third perforations 681, the number of third perforations 681 being half the number of first perforations 410; the plurality of third perforations are arranged in a circular array around the center of the groove, and their positions correspond to the positions of the first perforations; the third perforations are arc-shaped, and the distance between the ends of any two adjacent third perforations is greater than the diameter of the first perforation; the baffle can be adjusted to block half of the first perforations; this structural design can use the baffle to block the first perforations, which means that when backflushing to clean the filter cartridge, the number of filter cartridges that need to be cleaned at one time can be reduced, and the cleaning effect on the filter cartridge can be enhanced under the same air pressure; in addition, the baffle is driven to rotate by a motor, which also means that the brush kit will rotate during this process to clean the outer wall of the filter cartridge, cleverly utilizing the coordination between the structures.

[0050] More specifically, the usage of the suction system and backflush system includes the following steps:

[0051] More specifically, the usage of the suction system and backflush system includes the following steps:

[0052] S1, initiate the first low-pressure suppression action;

[0053] S2, after the low-pressure pressing action is completed, during the process of lifting the upper mold core, the suction system is activated to suction the gas entering the upper mold core; the gas and the dust mixed in are pumped into the filter, and the dust is filtered and separated.

[0058] S7, After the high-pressure pressing action is completed; the upper mold core is lifted, and after the upper mold core and the brick blank are separated, the back-blowing system is activated to clean the exhaust holes by blowing air until the preset height is reached; the pressing of this brick blank is completed.

[0059] Furthermore, when the filter device performs self-cleaning (when brick pressing is not being carried out), it includes the following steps:

[0060] B1, start the motor, drive the baffle to rotate to the first preset position, and block half of the first perforation;

[0061] B2, high-pressure gas is supplied to the backflush pack by an air compressor, and the backflush pack is used to backflush the corresponding half of the filter cartridge;
