Description

TECHNICAL FIELD

[0001] The present application relates to the field of sand blasting and paint spraying technology, in particular to a walking type sand blasting and paint spraying frame. BACKGROUND

[0002] In the process of processing metal steel, the metal steel needs to be sand blasted and painted to make the steel surface have certain wear resistance, corrosion resistance and different roughness. The shape of the steel is various, some of which are composed of continuous inclined planes and planes, and the whole is a zigzag structure.

[0003] At present, when sand blasting and paint spraying are performed on the steel with a zigzag structure, the sand blasting gun and the paint spraying gun are generally aimed at the surface of the steel for sand blasting. However, due to the zigzag structure of the steel, it is difficult to maintain the height between the sand blasting gun and the paint spraying gun and the surface of the steel. The place on the surface of the steel close to the spray head is sprayed more, and the place on the surface of the steel far from the spray head is sprayed less, resulting in uneven and insufficient sand blasting and paint spraying, so that the roughness of the steel after sand blasting and paint spraying is inconsistent, affecting the durability of the steel. In addition, a lot of sand blasting material and paint spraying material will be dispersed during the sand blasting and paint spraying process, and the dispersed sand blasting material and paint spraying material will fall on the surface of the steel. These sand blasting material and paint spraying material will block the subsequent sprayed sand blasting material and paint spraying material, resulting in less firm adhesion of the subsequent sprayed sand blasting material and paint spraying material.

[0016] The beneficial effects are:

[0017] During the pushing process of the staff, the sand spraying head moves above the plane of the steel material, and the sand spraying head sprays sanding material. The staff continues to push the spray frame, and the sand spraying head and the paint spraying head move to the inclined surface of the steel material. The spraying height between the sand spraying head and the paint spraying head and the steel material remains unchanged, so that the sanding material sprayed by the sand spraying head and the paint spraying head can better adhere to the surface of the steel material.

[0018] In addition, the rotation of the rotating disc drives the fixed T-shaped slot rod to move back and forth left and right, so that the sand spraying head and the paint spraying head move back and forth left and right, and at the same time, the sand spraying head and the paint spraying head respectively spray sanding material and paint material, so that the sand spraying head and the paint spraying head more fully and uniformly spray sanding material and paint material onto the steel material.

[0019] In addition, when the fixed rod, the transverse sliding rod, the sand spraying head and the paint spraying head move back and forth left and right, the back and forth movement of the fixed rod along the wave-shaped slot of the fixed wave-shaped slot rod makes the fixed rod, the transverse sliding rod, the sand spraying head and the paint spraying head move back and forth left and right at the same time, so that the spraying range of the sand spraying head and the paint spraying head is further expanded, and the sand spraying head and the paint spraying head more uniformly spray sanding material and paint material onto the steel material.

[0020] In addition, when the sand spraying head sprays sanding material, the main sand suction pipe can adsorb a small part of the sanding material that escapes to the front of the sand spraying head, so that the subsequent sprayed sanding material can be directly sprayed onto the surface of the steel material, so that the sanding material is more firmly attached to the surface of the steel material, thereby improving the sanding quality.

[0021] In addition, when the fixed curtain blocks a small part of the sanding material that escapes to the rear of the sand spraying head, the secondary sand suction pipe can adsorb a small part of the sanding material that escapes to the rear of the sand spraying head, and the fixed curtain can block the sanding material that the secondary sand suction pipe may not adsorb, so as to more completely adsorb the sanding material that escapes to the surface of the steel material, reduce the excess sanding material remaining on the surface of the steel material, and facilitate better paint spraying treatment of the steel material.
