Roughening machine for concrete treatment

Abstract

The invention relates to the technical field of building construction, and discloses a roughening machine for concrete treatment, which comprises a fixing plate, supporting columns are fixedly connected to the two sides of the top end of the fixing plate, roughening columns are hinged to the lower part of the outer wall of the fixing plate, grooves are formed in the roughening columns, inner fixing blocks are embedded in the lower parts of the side walls of the grooves, roughening knives are movably connected with notches of the roughening columns in a sleeved mode, and the top ends of the roughening knives are fixedly connected with movable plates. Rotation of lower movable rods and upper movable rods is controlled through magnetism of the inner fixing blocks, the purposes that the force applied by each roughening knife is the same, and the width and depth generated by roughening are the same are achieved, meanwhile, through the magnetic attraction characteristic of the inner fixing blocks and movable assemblies, rubber assemblies are extruded, upper fixing blocks are promoted to clamp and fix limiting blocks, the purpose of fixing the angle of the lower movable rods and the angle of the upper movable rods is achieved, and the roughening knives are prevented from contracting inwards due to large resistance of a concrete prefabricated part.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a napping machine for concrete treatment. Background technique [0002] In the construction industry, the napping machine is an important part of the concrete prefabricated component production line. It is mainly composed of a support column, a fixing plate, a napping column and a napping knife. When it works, the fixing plate is placed on the concrete precast component conveyor belt through the support column. , insert the roughing knife into the concrete, and draw a straight line texture with a certain depth and width on the surface of the prefabricated component, so as to ensure that the finished component has enough friction when it is used, so that the component can be completely combined with the subsequent concrete or other building materials, It effectively prevents the phenomenon of falling off and falling apart of the building, and the napping machine has ...

Problems solved by technology

[0004] In view of the deficiencies in the use of the existing napping machine proposed in the background technology, the present invention provides a napping machine for concrete treatment, which has the same napping effect on prefabricated components with different hardness, and effectively improves the roughness of the napping machine. The advantages of napping quality and work efficiency solve the technical problems raised in the above-mentioned background technology
