Description

Technical Field

[0001] The utility model relates to the technical field of ceramic injection machines, in particular to a feeding device of a vertical ceramic injection machine. Background Art

[0002] Ceramics, a general term for pottery and porcelain, are also a type of Chinese arts and crafts. As early as the Neolithic Age, my country already had painted and black pottery with a rugged, unadorned style. Pottery and porcelain have different textures and properties. Traditional Chinese ceramic arts and crafts are renowned worldwide for their high quality, aesthetic beauty, and artistic value. Currently, ceramic production requires the use of slurry injection machines.

[0003] After searching, the feeding device of the vertical ceramic injection molding machine with the announcement number CN 201257701Y includes a feeding barrel, a feeding screw, and a servo motor. One end of the feeding barrel is connected to the injection device, and the servo motor is fixed to the other end of the feeding barrel. The feeding screw is rotatably arranged in the feeding barrel and is driven to rotate by the servo motor. A feeding port connected to the feeding device is opened on the feeding barrel. The slurry of the feeding device enters the feeding barrel from the feeding port of the feeding barrel. The feeding screw rotates under the drive of the servo motor and pushes the slurry from the feeding barrel to the injection device. By adjusting the speed and rotation time of the servo motor, the feeding amount and flow rate of the slurry into the injection device can be controlled, and the quality of the product after injection molding is good; the outer surface of the feeding barrel is wrapped with a heating wire, and the heating wire can heat the slurry through the feeding barrel to keep the slurry at a sufficient temperature and will not condense due to too low temperature.

[0004] However, the above device still has some shortcomings during use. After use, residual materials will stick to the inside of the feeding tube and the feeding screw, which cannot be cleaned quickly, affecting subsequent use. At the same time, the feeding screw will wear and damage after long-term use, and cannot be quickly disassembled and replaced, which is inconvenient to use. Utility Model Content

[0010] Preferred technical solution four: A driving motor is fixedly connected to the upper surface of the upper cover, and an output end of the driving motor extends to the interior of the upper cover and is fixedly connected to the rotating rod.

[0011] Preferred technical solution five: a sealing gasket is fixedly installed on the inner top wall of the upper cover, and a sealing groove corresponding to the feeding pipe is opened on the lower surface of the sealing gasket.

[0012] Compared with the prior art, the utility model provides a feeding device of a vertical ceramic injection molding machine, which has the following beneficial effects: when in use, the material enters the interior of the feeding tube through the feeding port, and then the rotation of the driving motor drives the rotating rod and the feeding screw to rotate, thereby conveying the material out through the bottom end of the feeding tube. When the interior of the feeding tube and the feeding screw need to be cleaned, the connecting plate is driven to move by rotating the screw rod, thereby driving the clamping rod to be pulled out from the inside of the clamping groove on the feeding tube, releasing the lock between the upper cover and the feeding tube, and then the upper cover can be removed from the upper part of the feeding tube, so that the interior of the feeding tube and the feeding screw can be cleaned. At the same time, the feeding screw can be removed from the rotating rod by tightening the bolt for replacement, which is convenient and quick. When in use, the device can quickly install and disassemble the upper cover and the feeding tube, which is convenient for quick cleaning and replacement of the interior of the feeding tube and the feeding screw. It is easy to use and convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
