Automatic sand abrasion device

Abstract

An automatic sand abrasion device includes a shell, an integrated framework, a sand falling mechanism, a sand transport mechanism, a sand falling channel, a sample working frame and a circuit control cabinet, where the device adopts the transport belt and the second speed reduction motor to realize transportation of sand, and realizes that the weighed sand falls into the bottom of the abrasion device through the first speed reduction motor and the automatic weighing machine. The whole process can be automatically operated while parameters such as the operation time and the weight of abrasion sand are set, so that the detection efficiency for the abrasion resistance can be improved, and the labor cost is greatly reduced. The device is firm in structure and stable and reliable in work and improves the accuracy and efficiency of an experiment.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Chinese Patent Application No. 201910034694.3, entitled AUTOMATIC SAND ABRASION DEVICE and filed on Jan. 15, 2019, which is incorporated herein by reference for all purposes.FIELD OF THE INVENTION[0002]The present disclosure relates to the technical field of verification of sand abrasion resistance of coated surface paints, and more particularly relates to an automatic sand abrasion device.BACKGROUND OF THE INVENTION[0003]With the upgrading of automobile consumption, people pay more and more attention to the appearance of automobiles, and the more beautiful the appearance of an automobile is, the more popular the automobile is. The quality of a paint is directly related to whether the appearance of the automobile is accepted by the public. Therefore, automobile manufacturers pay special attention to the various properties of the paint. The abrasion resistance of the paint is directly related to whether t...

Benefits of technology

[0020]Compared with the prior art, the present disclosure has the beneficial effects that the automatic sand abrasion device in the present disclosure adopts the transport belt and the second speed reduction motor to realize transportation of the sand, and realizes that the weighed sand falls into the bottom of the abrasion device through the first speed reduction motor and the automatic weighing machine; the whole process can be automatically operated while parameters such as the operation time and the weight of abrasion sand are set, so that the detection efficiency for the abrasion resistance can be improved, the labor cost is greatly reduced, and the accuracy and efficiency of the experiment are improved; and furthermore, tiny dust produced in the operation process of the abrasion device can be discharged from the vent by disposing the shell and the vent in the shell, so as to eliminate the influence of the dust on the human health; in the present disclosure, the sand falls off uniformly and an initial downward speed of the sand at the upper port of the falling pipe is allowed to be close to zero as much as possible due to the

Problems solved by technology

This measure not only consumes a lot of manpower and material resources, but also has a great impact on human health since tiny dust may suff
