Description

Technical Field

[0001] This application relates to the technical field of ceramic blank production equipment, specifically a receiving device for high-pressure grouting production of ceramic blanks. Background Technology

[0002] In the high-pressure grouting production of ceramic blanks, the grouting port of the mold after mold closing needs to be connected to the output end of the delivery pump first, and the water and air vents outside the mold are opened. The delivery pump maintains a low speed and slowly injects the ceramic blank slurry into the mold under a certain pressure, allowing the slurry to initially fill the mold cavity, but at this stage, a dense blank is not formed. The power of the delivery pump is increased to inject more slurry into the mold cavity, raising the grouting pressure to a specified range, generally 0.6-0.9 MPa, for 80-160 seconds, allowing the slurry to enter the mold cavity more quickly and expelling any gas inside. After pressurized grouting, the delivery pump is replaced with a high-pressure pump for high-pressure grouting at a certain pressure and time, generally 1.2-1.6 MPa, with a pressurization time controlled at 200-300 seconds, further compacting and shaping the slurry under high pressure. After holding the pressure for a period of time, the high-pressure pump and other pipelines are shut off, allowing the blank to naturally solidify and form within the mold. Finally, by controlling the mold clamping assembly, the pressure inside the mold cavity is gradually restored to the external pressure of the mold, and then the mold closing assembly is controlled to separate the two parts of the mold.

[0003] After demolding, the blank needs to be sent to a drying equipment for drying. The drying temperature is controlled at 100-200℃, and the drying time is 2-8 minutes to remove moisture from the blank and improve its strength. Finally, the dried blank undergoes further processing, such as grinding, cutting, and drilling, to meet the precision and dimensional requirements of the finished product.

[0004] In actual production, a receiving device is needed to receive the blanks during demolding. Current technology mostly involves workers holding the receiving plate to lift the blanks. Due to the weight of the blanks, unloading them is time-consuming and labor-intensive. To improve unloading efficiency, some manufacturers use telescopic arms to move pallets for receiving. In practice, the user places the receiving plate on the pallet, and then the telescopic arm extends to send the receiving plate under the mold, where it receives the demolded blank. However, since the receiving plate is placed arbitrarily by workers, if the demolded blank does not land in the center of the receiving plate, it is very easy for the blank to be damaged during post-processing. Furthermore, the blank is prone to slipping when being moved via the receiving plate. Summary of the Invention

[0028] Please see Figure 1-6 This application provides the following technical solution: a receiving device for high-pressure grouting production of ceramic blanks, including a positioning shaft 6; the positioning shaft 6 is rotatably connected to a sleeve 1 via a bearing disposed on its outer side, the lower end of the outer side of the sleeve 1 is provided with an annular tooth 7, a reduction motor 5 is installed on the lower end of the outer side of the positioning shaft 6, the output shaft of the reduction motor 5 is connected to a gear 4, the gear 4 meshes with the annular tooth 7, and the sleeve 1 is connected to a tray 10 via a support arm 9 disposed on its outer side.

[0029] Specifically, the geared motor 5 drives the gear 4 to rotate, and the gear 4 drives the sleeve 1 to rotate, thereby realizing the position switching of the tray 10. The sleeve 1 only rotates between 0 and 90 degrees.

[0030] A hollow cylinder 11 is provided in the middle of the lower surface of the tray 10. Four sliding grooves 14 are evenly distributed on the upper surface of the tray 10. T-shaped sliders 12 are slidably connected to the sliding grooves 14. A power mechanism for controlling the T-shaped sliders 12 to move toward the center of the tray 10 is installed inside the hollow cylinder 11.

[0031] Specifically, the receiving plate is placed on the upper surface of the tray 10, and then the four T-shaped sliders 12 move synchronously toward the center of the tray 10 until the receiving plate is pushed to the very center of the tray 10.

[0032] Furthermore, the lower end of the positioning shaft 6 is fixed to a base on the ground.

[0033] Specifically, the positioning shaft 6 is used to support the weight of the entire receiving equipment.

[0034] Furthermore, a positioning plate 2 is provided on the upper side of the outer side of the positioning shaft 6, a touch switch 3 is provided on the front side of the positioning plate 2, and a positioning rod 8 is provided on the upper end of the sleeve 1. When the positioning rod 8 contacts the touch switch 3, the tray 10 is just located at the receiving station.

[0035] Specifically, during the process of the geared motor 5 driving the tray 10 to rotate, when the positioning rod 8 contacts the touch switch 3, the tray 10 is just located at the receiving station, at which point demolding can be performed.

[0036] Furthermore, multiple cylindrical rollers 13 are linearly and evenly distributed on the upper surface edge of the T-shaped slider 12 near the center of the tray 10, and the cylindrical rollers 13 are rotatably connected to the upper surface of the T-shaped slider 12.

[0037] Specifically, the cylindrical roller 13 can effectively reduce the friction between the receiving plate and the T-shaped slider 12 when the receiving plate is adjusted.

[0038] Furthermore, the upper surface of the tray 10 is evenly distributed with a plurality of support columns 15, and the upper surface of the support columns 15 is equipped with omnidirectional ball supports.

[0039] Specifically, the omnidirectional ball support can both lift the receiving plate and increase the ease of adjusting the receiving plate.

[0040] Furthermore, multiple support columns 15 are arranged in an X-shape on the upper surface of the tray 10.

[0041] Furthermore, there are two power mechanisms: the first power mechanism controls the synchronous movement of the two front and rear T-shaped sliders 12, and the second power mechanism controls the synchronous movement of the two left and right T-shaped sliders 12.

[0042] Specifically, when clamping the receiving plate, the front and rear T-shaped sliders 12 move synchronously toward the center of the tray 10 until the receiving plate is clamped. Then, the left and right T-shaped sliders 12 move synchronously toward the center of the tray 10 until the receiving plate is adjusted to the center position.

[0043] Furthermore, the power mechanism includes two hollow rectangular blocks 17 installed on the outer side of the hollow cylinder 11. The two hollow rectangular blocks 17 are symmetrically arranged about the hollow cylinder 11. A slider 19 is slidably connected to the inner side of the hollow rectangular block 17. The outer side of the slider 19 away from the hollow cylinder 11 is connected to a T-shaped slider 12 through a straight rod 16. A rack 20 is provided on the outer side of the slider 19 near the hollow cylinder 11. A stepper motor 18 is installed in the center of the inner side of the hollow cylinder 11. A gear 2 is installed on the output shaft of the stepper motor 18. The gear 2 meshes with the two racks 20 arranged in front and behind.

[0044] Specifically, the stepper motor 18 can achieve the synchronous approach and distance of the two T-shaped sliders 12 through the gear and rack transmission mechanism.

[0045] In use: Place the outer rectangular receiving plate on the upper surface of the support column 15, then start the stepper motor 18 that controls the synchronous movement of the two front and rear T-shaped sliders 12. The stepper motor 18 drives the gear 2 to rotate, and the gear 2 drives the two racks 20 to move synchronously. The racks 20 pull the T-shaped sliders 12 towards the center through the straight rod 16 until the T-shaped sliders 12 clamp the rectangular receiving plate from both ends. Then start another stepper motor 18, which drives the left and right T-shaped sliders 12 to clamp the rectangular receiving plate from both sides using the same working principle.

[0046] Start the hydraulic lift of the demolding mechanism. The hydraulic lift will move the upper mold shell upward. At this time, the die-cast blank will move upward along with the upper mold shell.

[0047] The geared motor 5 is then started. The geared motor 5 rotates the tray 10 to the underside of the upper mold housing through the gear transmission device. The demolding mechanism performs demolding. The demolded blank is located in the center of the rectangular receiving plate. After receiving the material, the geared motor 5 rotates in the opposite direction to move the tray 10 out. Then, the four T-shaped sliders 12 are released, and the worker can move the die-cast blank along with the rectangular receiving plate.
