Production line for surface sanding of FRP (Fiber Reinforced Plastic) grating and sanding method

Abstract

The invention relates to a production line for surface sanding of FRP (Fiber Reinforced Plastic) grating and a sanding method. The production line comprises an automatic conveying line, wherein a truss mechanical arm is arranged at the feeding end of the automatic conveying line; the automatic conveying line sequentially penetrates through an inner layer resin automatic gluing machine and an automatic sanding machine; a first overturning frame is arranged at a discharging port of the automatic sanding machine; an outlet of the first overturning frame is communicated with an inlet of a first heating oven; an outlet of the first heating oven is communicated with an inlet of a second overturning frame; an automatic surface layer resin gluing machine is arranged at an outlet of the second overturning frame; the automatic conveying line penetrates through the automatic surface layer resin gluing machine; a second heating oven is arranged at a discharging port of the automatic surface layer resin gluing machine; an automatic discharging device is arranged at an outlet of the second heating oven; and the automatic conveying line penetrates through the automatic discharging device. Compared with manual sanding, by applying the production line for surface sanding of FRP grating and the sanding method provided by the invention, the production efficiency is improved by four times; and the production line is provided with a dust removal system and an air knife purging device, so that the workshop environment is improved, meanwhile, sanding of products is uniform, and the quality is reliable.

Description

technical field [0001] The invention relates to a production line and a sanding method for sanding the surface of an FRP grid. Background technique [0002] At present, the current situation of grating sanding in China is manual handling, resin coating, and sanding; the entire sanding process requires manual handling 4 times, which is labor-intensive, and the manual coating of inner and surface resins is uneven, and sanding is also difficult. Uneven; the inner layer and surface layer of sand paving have a strong smell of resin, which is harmful to the health of operators. It is not environmentally friendly. Manual sand paving cannot use the dust removal system, which has a great impact on the workshop environment. The dust layer is large, and the operators are covered with dust. It will affect the health of operators; the cost of manual operation is high, and the product profit is low. Contents of the invention [0003] The object of the present invention is to provide a ...
