Method and device for manufacturing dovetail groove in back side of ceramic tile

Abstract

The invention discloses a method and device for manufacturing a dovetail groove in the back side of a ceramic tile. The device comprises a wedge lifting cover (b) and is characterized in that inward stretching lifting arms are arranged on the left side edge and right side edge of the wedge lifting cover respectively, an inner cavity is divided into a left cavity part and a right cavity part by a dovetail combined insert, a wedge body side frame and a half-dovetail component are arranged in each cavity part, and each half-dovetail component can make contact with the dovetail combined insert; an upper ejector plate on each wedge body side frame can move downwards in the corresponding cavity part onto the corresponding lifting arm and be limited by the lifting arm, and a reset spring is arranged between a spring slot formed in the wedge body side frame in each cavity part and a reset spring slot formed in the adjacent half-dovetail component; an insert body of the dovetail combined insert can be combined with two half dovetails located at the two sides of the dovetail combined insert respectively to form a complete dovetail part, and the complete dovetail part is inserted into ceramic tile powder to enable a dovetail groove to be formed in the back side of the ceramic tile; when the dovetail combined insert is pulled upwards in place, the dovetail part which can be pulled out of the dovetail groove and is free of the insert body is formed with width reduced. The method and device have the characteristics that the manufacturing method and device are simple, and operation is convenient.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a method and equipment for manufacturing dovetail grooves on the back of ceramic tiles. 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. In view of the defects in the original tile production process, the designer created a product with a dovetail groove on the back of the tile after long-term research and development, and then installed it on the interior and exterior walls of the building. When pasted by AB structural glue or cement mortar, it can...
