Description

Technical Field

[0001] This utility model relates to the field of ceramic grouting technology, and in particular to an intelligent ultra-high pressure ceramic grouting machine. Background Technology

[0002] Currently, there are three main ceramic production and forming processes: rolling, high-pressure grouting, and hollow grouting. Among them, high-pressure grouting is the most widely used. However, high-pressure grouting of ceramic molds is mostly done manually. First, the upper and lower molds are joined together manually. Then, the joined molds are manually moved to the grouting platform, aligning the grouting hole at the bottom of the lower mold with the grouting port on the platform. Following this process, the joined molds are stacked sequentially, aligning the grouting holes of adjacent molds. After a certain number of joined molds are stacked, a pressure plate above the grouting platform presses down onto the top mold (i.e., the top of the top mold). The process involves a frame with screws mounted on it. These screws are connected to a steel plate (lower pressure platform). The screws are manually operated to tighten the steel plate, thereby sealing the corresponding holes at the top of the upper mold. The grouting platform contains grouting pipes connected to the grouting port of the lower mold. These pipes are connected to an external high-pressure tank, which provides a propulsive force to the ceramic slurry, pushing it into the mold cavity to form a ceramic blank. After grouting, workers manually move the molds one by one to the workbench, then manually open the molds and remove the ceramic blanks. This manual grouting method is labor-intensive, inefficient, requires a large amount of manpower, and is costly.

[0003] Meanwhile, insufficient slurry injection pressure leads to inconsistent product quality. When the slurry injection pressure of the mold is too low, it will result in insufficient pressure inside the mold cavity. This will cause problems such as shrinkage of the ceramic clay body (for example, if there is a foot on the bottom of a square or oval ceramic plate, several visible indentations will appear on the front of the plate), obvious joining lines (chemical additives are added during the ceramic production process to increase the fluidity of the slurry, resulting in a higher density in this part of the clay body, and a raised joining line will appear on the finished ceramic product), and water ripples (due to low pressure, the slurry moves slowly and intermittently inside the mold cavity, thus leaving marks). These problems will eventually be more obvious in the finished product, resulting in poor product quality. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent ultra-high pressure ceramic grouting machine that can automate the grouting of ceramic molding molds. Compared with the conventional manual operation, this grouting machine has a high degree of automation and is easy to operate, saving a lot of manpower and reducing labor costs. At the same time, it has multiple grouting stations, which can grout multiple molds at the same time, greatly improving work efficiency. In addition, the use of diaphragm pump pressurized grouting can provide stable, fast and uniform high pressure, ensuring that the slurry fills the mold cavity evenly. At the same time, under higher pressure, the slurry propulsion speed is fast, which can avoid the appearance of marks such as slurry lines, slurry shrinkage, and water ripples on the product, improving product quality. Moreover, the demolding hardness of the product clay blank is improved, and it is not easy to deform.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] A smart ultra-high pressure ceramic grouting machine, comprising

[0007] The rack includes a workbench, a support column connected to the workbench, a pressure mounting bracket connected to the upper part of the support column, and a cabinet connected to one end of the workbench.

[0008] The grouting drive mechanism is installed inside the cabinet and is also connected to several grouting pipes; the workbench is provided with several grouting stations, and the grouting pipes are arranged inside the workbench, with one end of each grouting pipe extending to the bottom of a corresponding grouting station; the end of each grouting pipe for grouting is also equipped with several grouting interfaces, and several first grouting ports are opened at the grouting stations corresponding to the several grouting interfaces;

[0009] A plurality of pressure-driving mechanisms are mounted on a pressure-mounting bracket; each pressure-driving mechanism is also connected to a pressure plate, and each pressure plate is arranged above a grouting station.

[0010] Furthermore, the grouting drive mechanism includes a diaphragm pump and a grout inlet pipe connected to the inlet of the diaphragm pump; the grouting pipe is connected to the outlet of the diaphragm pump, and each grouting pipe is also connected to an angle valve.

[0011] Furthermore, each of the grouting pipes is also connected to a pressure relief valve.

[0012] Furthermore, the pressure-down drive mechanism includes a hydraulic cylinder mounted on the pressure-down mounting bracket, and a hydraulic pump arranged inside the cabinet and connected to the hydraulic cylinder; the pressure plate is connected to the output shaft of the hydraulic cylinder.

[0013] Furthermore, the pressing drive mechanism also includes several lifting guide rods mounted on the pressing mounting bracket, with the top of the pressing plate connected to the lifting guide rods.

[0014] Furthermore, a dust cover is connected to the top of the lower pressure plate, and the dust cover encloses a portion of the lifting guide rod.

[0015] Furthermore, an upper limit switch and a lower limit switch are also installed on the upper part of the support column near the lower pressure plate, with the lower limit switch located below the upper limit switch.

[0016] By adopting the above solution, the beneficial effects of this utility model are:

[0017] This invention enables automated grouting of ceramic molding molds. Compared to conventional manual operation, this grouting machine is highly automated and easy to operate, saving significant manpower and reducing labor costs. It features multiple grouting stations, allowing for simultaneous grouting of multiple molds, all operating independently without interference, greatly improving work efficiency. Furthermore, the use of a diaphragm pump for pressurized grouting provides stable, rapid, and uniform high pressure, ensuring even filling of the mold cavity with grout. At higher pressures, the grout propulsion speed is faster, preventing defects such as grout lines, shrinkage, and water ripples, thus improving product quality. Additionally, the molded clay blanks exhibit increased hardness upon demolding, making them less prone to deformation. Attached Figure Description

Detailed Implementation

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1 to 5 As shown, this utility model provides an intelligent ultra-high pressure ceramic grouting machine. In one embodiment, it includes...

[0027] The rack includes a workbench 1, a support column 2 connected to the workbench 1, a pressure mounting bracket 3 connected to the upper part of the support column 2, and a cabinet 4 connected to one end of the workbench 1.

[0028] Grouting drive mechanism 5 is installed inside cabinet 4 and is also connected to several grouting pipes 6; several grouting stations are provided on the workbench 1, and the grouting pipes 6 are arranged inside the workbench 1, with one end of each grouting pipe 6 extending to the bottom of a corresponding grouting station; several grouting interfaces 61 are also installed on the end of each grouting pipe 6 for grouting, and several first grouting ports 11 are opened at the grouting stations corresponding to the several grouting interfaces 61;

[0029] A plurality of pressure driving mechanisms 7 are mounted on a pressure mounting frame 3; each pressure driving mechanism 7 is also connected to a pressure plate 8, and each pressure plate 8 is arranged above a grouting station.

[0030] In this embodiment, a control screen is installed on the front of the cabinet 4, and indicator lights are installed on the top of the cabinet 4. A foot cup is installed at each of the four corners of the bottom of the rack. Four support columns 2 are provided, connected to the four corners of the workbench 1 respectively. A downward mounting bracket 3 is connected between the upper parts of the four support columns 2. The number of grouting stations can be freely set according to the actual usage environment and is not limited thereto. In this embodiment, for example... Figure 1 As shown, there are two grouting stations, forming a dual-station grouting machine. The two stations are independent of each other and do not interfere with each other. Figure 2 As shown, there is one grouting station, which is a single-station grouting machine. The number of grouting pipes 6 and the number of pressure drive mechanisms 7 and pressure plates 8 are consistent with the number of grouting stations. The first grouting port 11 on each grouting station is arranged to correspond to the grouting interface 61 on the grouting pipe 6. When the mold is placed on the workbench 1, the grouting hole at the bottom of the mold must correspond to the first grouting port 11 (the molds are of different sizes, and the center of the mold and the center of the workbench 1 must be approximately coincident. The grouting hole at the bottom of the mold must coincide with the first grouting port 11 on the workbench 1 that is closest to the grouting hole. The extra first grouting ports 11 are plugged with threaded plugs to prevent grout leakage and pressure loss). There are multiple first grouting ports 11 on the grouting station, which can be used for molds of different sizes and have strong compatibility.

[0031] In this embodiment, the grouting drive mechanism 5 includes a diaphragm pump 51 and a grout inlet pipe connected to the inlet of the diaphragm pump 51; the grouting pipe 6 is connected to the outlet of the diaphragm pump 51, and each grouting pipe 6 is also connected to an angle valve 52. At the same time, each grouting pipe 6 is also connected to a pressure relief valve 53. The slurry inlet pipe is connected to the external slurry storage tank. The diaphragm pump 51 is used to provide power (the power of the diaphragm pump 51 is controlled by the gas proportional valve) to draw the slurry from the slurry storage tank and then inject it into the mold cavity through the slurry injection pipe 6, the first slurry injection port 11, and the slurry injection hole. Each slurry injection pipe 6 is equipped with an angle valve 52, which is controlled by a solenoid valve to open or close to control the slurry injection. At the same time, each pipe is also equipped with a pressure relief valve 53, which is controlled by a solenoid valve to open or close to control the pressure relief after the slurry injection is completed (if the pressure is not relieved, the excess slurry inside the mold injection hole may leak onto the workbench 1 and the mold surface, affecting hygiene and requiring manual cleaning, which affects work efficiency).

[0032] In one embodiment, the pressing drive mechanism 7 includes a hydraulic cylinder 71 mounted on the pressing mounting bracket 3, and a hydraulic pump 72 arranged inside the cabinet 4 and connected to the hydraulic cylinder 71; the pressing plate 8 is connected to the output shaft of the hydraulic cylinder 71. The hydraulic pump 72 provides power to the hydraulic cylinder 71, so that the hydraulic cylinder 71 drives the pressing plate 8 to rise and fall to press the mold, and the pressure of the hydraulic cylinder 71 can be fed back by a pressure sensor installed on its oil circuit system, thereby realizing closed-loop control. At the same time, in order to improve the stability of the pressing plate 8 rising and falling, the pressing drive mechanism 7 also includes a plurality of lifting guide rods 73 mounted on the pressing mounting bracket 3, and the top of the pressing plate 8 is connected to the lifting guide rods 73.

[0033] Furthermore, a dust cover 74 is connected to the top of the lower pressure plate 8, and the dust cover 74 encloses a portion of the lifting guide rod 73. The dust cover 74 can enclose the lifting guide rod 73 and a portion of the hydraulic cylinder 71, thus preventing dust accumulation. Additionally, an upper limit switch and a lower limit switch are installed on the upper part of the support column 2 near the lower pressure plate 8, with the lower limit switch positioned below the upper limit switch. The upper and lower limit switches can limit the lifting stroke of the lower pressure plate 8.

[0034] The working process of this utility model is as follows:

[0035] 1) Manually place the mold on the grouting station on the workbench 1, so that the grouting hole of the bottom mold corresponds to the first grouting port 11 on the grouting station, and the mold is approximately below the center of the lower pressure plate 8 corresponding to the grouting station.

[0036] 2) Continuously stack the molds upwards (so that the grouting holes of adjacent molds correspond), and the height of the stacked molds exceeds the position of the lower limit switch and is lower than the upper limit switch, that is, it is located between the lower limit switch and the upper limit switch.

[0037] 3) Select the automatic start button on the control panel. The background system controls the corresponding lower pressure plate 8 to press down. When it contacts the top of the uppermost mold, the pressure sensor in the hydraulic cylinder 71 oil circuit system connected to the lower pressure plate 8 detects that the set pressure has reached the predetermined value. The background system then controls the hydraulic pump 72 to stop working and maintain pressure. At the same time, the gas proportional valve and the mud control angle valve 52 open. The proportional valve outputs the set pressure to control the pressure of the mud output by the pump. At this time, the countdown begins (the pressure holding time and grouting time are different for each product). When the countdown ends, the grouting angle valve 52 and the proportional valve are closed. Then the lower pressure plate 8 rises to the upper limit switch.

[0038] 4) Manual or robotic arms lift the mold out and remove the product inside, and repeat this process.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
