Device and method for processing circular single dovetail grooves in back surfaces of ceramic tiles

Abstract

The invention relates to a processing device and a processing method for a circular single dovetail groove on the back of a ceramic tile. The processing device includes a hollow pressure seat lifting cover fixed at the lower end of an air hammer and a pressure seat sliding sleeve matching with the pressure seat lifting cover. seat; the upper end of the lifting cover of the press seat is provided with a cover surface, and the lower end is provided with a lifting arm extending inward; And the lifted arm located in the cover of the pressure seat lifts; the lifted arm is limited and slid in the cavity formed by the cover surface and the lifting arm; the pressure seat is evenly distributed with a plurality of vertical hollow holes Cylinder; the upper end of the hollow cylinder is flush with the top of the press seat, and the lower end protrudes downward from the press seat, and the part protruding from the press seat is formed by sequentially overlapping a plurality of first fan-shaped pressing pieces that can be turned inside and outside; the The processing device and processing method for the circular single dovetail groove on the back of the ceramic tile can effectively, quickly and stably form the circular single dovetail groove.

Description

technical field [0001] The invention relates to a processing device and a processing method for a circular single dovetail groove on the back of ceramic tiles, belonging to the field of ceramic tile production equipment. Background technique [0002] The back of the original tiles has no dovetail shape, only lattice or patterns. After construction and installation, glue point paste or cement wet paste is used on the wall. In the case of special climate temperature difference, especially under the sun exposure, when the expansion of the tile and the main body is inconsistent, the tile plate is prone to detachment, causing the tile panel to fall off. Life and property have brought great harm. Patent No. CN105082332A discloses a manufacturing method and equipment for dovetail grooves on the back of ceramic tiles, including a press seat lift cover, which is characterized in that the left and right sides of the press seat lift cover are respectively provided with inwardly extend...

AI Technical Summary

Problems solved by technology

When pasted by AB structural glue or cement mortar, it can be squeezed into the dovetail groove, and it will form a dovetail shape after drying to achieve a physical firm combination, so that there will be no phenomenon that the tile plate is separated from the main body; but this technology can only form long strips Shaped dovetail grooves, while long dovetail grooves only have the function of one-way support, and there is no supporting force in the length direction of the dovetail groove, which greatly limits the application range of ceramic tiles produced by this technology, especially not suitable for tiles with The field of anisotropic stress; and when the long strip dovetail groove is pasted on the wall, the glue or mortar needs to be large, and the cost is high; The stress is different, and the tiles are prone to chipping, creating a hazard

The above problems can be solved by using a circular single dovetail groove, but this technology cannot be used for the forming of a circular single dovetail groove, because the forming of a circular single dovetail groove has a circular diameter change process, and this technology is used to form a circular single dovetail groove will cause powder to squeeze into the dovetail
