Sand blasting paint removing device for plastic bumper of scraped car

Abstract

The invention discloses a sand blasting paint removing device for a plastic bumper of a scraped car. The sand blasting paint removing device comprises a high pressure air generating module, a sand mixing module, a plastic injection module, a workpiece loading and transmission module and an electric control module, wherein the plastic injection module comprises a hollow main box and a plurality of spray gun groups mounted at the top of the main box; spray gun group swinging mechanisms used for swinging the spray gun groups are arranged on the spray gun groups; the workpiece loading and transmission module horizontally penetrates through the main box, is positioned below the spray gun groups, and comprises at least two groups of chain transmission mechanisms which are parallel and are arranged at the same height; driving sprockets on the same side are connected through a rigid shaft; the rigid shaft drives the driving sprockets to simultaneously rotate under the driving of an external power source; and a plurality of clamping parts used for clamping workpieces are uniformly arranged between adjacent chains. According to the sand blasting paint removing device, the operation process is simple, the paint removing efficiency is high, the effect is good, the labor intensity is relatively low, the environmental pollution is less, and the device is applicable to paint removing of large-batch bumpers and other waste structural parts.

Description

Technical field [0001] The invention relates to a product recovery device for automobile exterior trim parts, in particular to a sandblasting and paint removal device for retired automobile plastic bumpers. Background technique [0002] At present, my country’s car ownership has exceeded 100 million, and car production and sales are still showing a steady growth trend. In developed countries where the car market is relatively mature, the average car scrap rate (scrap / ownership) is 6%. In the period of rapid growth of automobile consumption, the current automobile scrap rate cannot reach this level. It is estimated that the annual automobile scrap volume is about 5 million, and it is showing an increasing trend year by year. Due to the advantages of lightweight and the development of new lightweight automotive materials, the amount of plastics used in automobiles is increasing year by year. As one of the largest plastic parts in automobiles, automobile bumpers have great recycling...
