The invention relates to the technical field of decoration, and discloses a gluing device for decoration, which comprises a moving trolley, a gluing cylinder, a rotary material changing mechanism, a hydraulic
extrusion mechanism, an angle adjusting mechanism and an automatic tracing mechanism, according to the device, firstly, constant-speed movement of the device is achieved through the arrangement of a driving wheel, meanwhile, an automatic tracing mechanism is installed in a
brick joint, so that the device moves at a
constant speed along the
brick joint, meanwhile, glue in a glue
pipe is extruded into a gluing
barrel through a hydraulic
extrusion mechanism, and part of the glue is stored in the gluing
barrel; and when the glue in the glue
pipe is extruded out, the glue stored in the gluing
barrel is extruded out, so that uninterrupted and non-stop gluing is realized, the glue is uniformly injected into the
brick joints, and in the whole process, the glue outlet speed and the
moving speed of the equipment are the same; while the gluing uniformity of the equipment is ensured, the labor amount of workers is reduced, and the working efficiency of the equipment is improved.
