When in use, the components of the tray lifting component are required to be reliably connected and uniform in size, meanwhile, the tray lifting component hopes to move linearly, and interference to other objects is avoided in the moving process.
The jacking mechanism commonly used for realizing the functions in the prior ceramic mechanical equipment uses a crank rocker mechanism, a motor drives a crank to rotate through a speed reducer, and the crank pushes a connecting rod to act, and the connecting rod drives a connecting frame rocker to rotate. The lifting component is connected with the rocking bars through a movable hinge structure, and in order to realize stable lifting, the crank rocking bar mechanism uses at least four rocking bars with parallel equal length, and the lifting component generates translation through rotation of the rocking bars to realize one jacking of a small stroke of a product. The hinge of the connecting rod mechanism uses a bearing and a round rotating shaft. The mechanism principle and structure for realizing the jacking by adding the translation of the crank rocker are relatively simple, and are adopted by most equipment manufacturers. However, the lifting component can not realize linear motion due to small-amplitude position change caused by translation, so that interference can be easily caused to other objects for certain products with special requirements. Meanwhile, due to the fact that a plurality of rockers are used repeatedly, the installation distance is 2-3 meters, the common structure is uniform and poor due to the fact that machining errors of the shaft length, and the connection points of the jacking components are difficult to achieve uniform working stroke.
