Description

Technical Field

[0001] This utility model relates to the field of ceramic powder conveying technology, and more specifically, to a ceramic powder quantitative conveying device. Background Technology

[0002] Ceramic powder is a raw material powder used in the preparation of ceramics. It is a pure-phase crystalline substance formed by mixing and calcining inorganic compounds composed of metallic and non-metallic elements. It has a precise chemical composition and specific particle characteristics, and is the core basic material for ceramic products. In addition, ceramic powder can be used as an additive in industrial materials, a component of high-tech products, and a raw material for daily necessities. Its core functions include improving material strength, high-temperature resistance, and insulation, and it plays a role in adsorption and filling in cosmetics, coatings, and other fields. When using ceramic powder, it is necessary to strictly control the amount of ceramic powder used. However, existing methods require manual weighing of ceramic powder, which is inconvenient and makes it difficult to transport a quantitative amount of ceramic powder into the equipment. Therefore, we propose a ceramic powder quantitative conveying device. Utility Model Content

A third reduction motor 23 is fixedly installed at one end of each of the two conveying cylinders 21. The output shafts of the two third reduction motors 23 extend into the inner cavity of the conveying cylinder 21 and are fixedly connected to the second spiral conveying rod 24 through a coupling. The inner diameter of the slide groove 18 is equal to the outer diameter of the slide column 20 to ensure the stability of the slide column 20 sliding in the inner cavity of the slide groove 18. The side of the second spiral conveying rod 24 is in contact with the inner wall of the conveying cylinder 21 to ensure that the second spiral conveying rod 24 can push the ceramic powder to move smoothly in the conveying cylinder 21.

[0020] Example 3: Based on Embodiment 1 and Embodiment 2, such as Figures 1 to 5 As shown, a threaded plug 25 is threaded onto the top surface of the storage hopper 10, and the bottom end of the threaded plug 25 extends into the inner cavity of the storage hopper 10. Ceramic powder is added into the inner cavity of the storage hopper 10 by removing the threaded plug 25. A through hole 28 is provided in the middle of the moving seat 6, and the storage hopper 10 passes through the inner cavity of the through hole 28. Multiple self-locking casters 30 are fixedly installed on the bottom surface of the base plate 1. The self-locking casters 30 are used to move the device and support it. A controller 31 is fixedly installed on the side of the support frame 2. The controller 31 controls the first reduction motor 5, the second reduction motor 26, the electric control valve 11, the third reduction motor 23, and the electric push rod 14 through wires.

[0021] It should be noted that this utility model is a quantitative conveying device for ceramic powder. In use, firstly, the threaded plug 25 is removed, and the ceramic powder to be fed is placed into the inner cavity of the storage hopper 10. The weight of the hanger 9, the second reduction motor 26, the storage hopper 10, and the ceramic powder is weighed as a whole using the weighing sensor 8. Then, the electric push rod 14 is activated, driving the U-shaped frame 19 and the sliding column 20 to move up and down. The sliding column 20, by sliding within the groove 18, pushes the support plate 16 and the conveying cylinder 21 to rotate around the rotating seat 15, causing the top of the conveying cylinder 21 to move... Move the device above the feed inlet of the processing equipment, then open the electrically controlled valve 11 at the bottom of the storage hopper 10, and start the second reduction motor 26 to drive the first spiral conveyor rod 27 to rotate. The first spiral conveyor rod 27 drives the ceramic powder in the inner cavity of the storage hopper 10 to fall into a receiving hopper 22, and the ceramic powder in the inner cavity of the receiving hopper 22 enters the inner cavity of the conveying cylinder 21. At this time, start the third reduction motor 23 to drive the second spiral conveyor rod 24 to rotate, and the second spiral conveyor rod 24 pushes the ceramic powder in the inner cavity of the conveying cylinder 21 to move into the processing equipment. In addition, the weighing sensor is used to... The device 8 monitors the weight of the ceramic powder inside the storage hopper 10 in real time. When the weight in the storage hopper 10 decreases by a predetermined amount, the solenoid valve 11 is activated and closed. Then, the first reduction motor 5 is activated to drive the screw 3 to rotate. Through the threaded engagement between the screw 3 and the moving seat 6, the moving seat 6 and the storage hopper 10 are moved. When the side of the moving seat 6 contacts a contact sensor 12, the first reduction motor 5 is closed. At this time, the solenoid valve 11 moves above another receiving hopper 22, opening the solenoid valve 11 so that a certain amount of ceramic powder inside the storage hopper 10 falls into the other receiving hopper. In one receiving hopper 22, the ceramic powder is quantitatively conveyed by the conveying cylinder 21 below the other receiving hopper 22. Finally, the first reduction motor 5 is started to drive the screw 3 to reverse. Through the threaded engagement between the screw 3 and the moving seat 6, the moving seat 6 and the storage hopper 10 move in opposite directions. When the side of the moving seat 6 contacts another contact sensor 12, the first reduction motor 5 is turned off again, and a certain amount of ceramic powder in the inner cavity of the storage hopper 10 is fed back into the receiving hopper 22 so that the ceramic powder can be conveyed again by the other conveying cylinder 21.
