Tile dry cast machine grinding head structure

Abstract

The invention discloses a tile dry cast machine grinding head structure which comprises a shell and a main shaft. The main shaft is installed in the shell, and the front end of the main shaft is provided with a grinding disc; the tile dry cast machine grinding head structure furthermore comprises a drive device and a lifting device, the drive device comprises a drive shaft, and the drive shaft is in transmission connection with the main shaft; and the lifting device comprises a sleeve shaft and a lifting power source, the main shaft internally sleeves the sleeve shaft, the periphery of the sleeve shaft is provided with a connection piece, and the lifting power source drives the connection piece to perform axial movement along the main shaft. The drive device drives the main shaft to perform high-speed rotation, and then vertical movement of the main shaft is controlled automatically or manually through the lifting device so that a grinding head can perform lifting knife feeding automatically or manually in the grinding process; and grinding quality of the grinding head is improved, and the polishing effect of a tile is better.

Description

technical field [0001] The invention relates to a grinding device, in particular to a dry polishing machine for ceramic tiles. Background technique [0002] There are various processing machines for processing tiles or stones. As far as the machines used for the front surface of long strips of tiles or stones are concerned, the machines currently on the market basically have two functions of workpiece forming and polishing. Forming and polishing operations create a linear operation, increasing throughput and reducing labor costs. [0003] In order to make the resin grinding wheel press tightly on the processing surface of the workpiece during polishing, it is usually necessary to install a lifting mechanism or device that can lift the grinding wheel in the equipment responsible for polishing in the above-mentioned processing machinery, so that during operation, the wear of the grinding wheel becomes smaller. Finally, the gap between the machined surface and the workpiece is...

Problems solved by technology

[0003] In order to make the resin grinding wheel press tightly on the processing surface of the workpiece during polishing, it is usually necessary to install a lifting mechanism or device that can lift the grinding wheel in the equipment responsible for polishing in the above-mentioned processing machinery, so that during operation, the wear of the grinding wheel becomes smaller. Finally, the gap between the machined surface and the workpiece is compensated. In the traditional technology, this lifting mechanism is equipped with a rotating shaft and a motor on the polishing machine base. The rotating shaft and the motor are connected by a belt, and a grinding wheel is installed at one end of the rotating shaft. After being connected to the frame and connected with the piston rod of the cylinder, or the polishing base is completely supported by the piston rod of the cylinder, the polishing base can be flipped or raised and lowered by manually operating the expansion and contraction of the cylinder to achieve the lifting and lowering of the grinding wheel. Purpose, this technology theoretically meets the aforementioned gap compensation requirements, but in practical applications, the polishing effect is not good, because the cylinder pushes the polishing machine base to press the grinding wheel on the rotating shaft against the workpiece during work. On the surface, in a certain period of time, theoretically, the pressure exerted by the cylinder on the workpiece and the length of the piston rod protruding are a certain value, but in the polishing process, jumping usually occurs, most of which are caused by the surface of the workpiece However, the inherent expansion and contraction of the cylinder itself is relatively slow, and it cannot follow this sudden sudden external change, so it often leads to stepped wear marks on the processed workpiece, which will seriously cause the workpiece to break.
