Embodiment Construction

[0027] see Figure 1-Figure 2 As shown, the present invention discloses an automatic cyclic sand shakeout wear resistance test device, which includes a square frame-shaped integral support 2, a sand shakeout mechanism, a transmission mechanism and a control system 4;

[0028] The bottom of the integral support 1 is provided with adjustable feet 11; adjusting the height of the feet can adjust the height and horizontal balance of the whole device.

[0029] The sand shakeout mechanism is fixed on one side of the overall support 1, and from top to bottom are the funnel 21, the conduit 22, the test plate fixture 23, the sandbox 24, and the sandbox cylinder 25. The test plate fixture 23 is an inclined structure And the lower end falls above the sandbox 24; the conduit 22 is made of metal, with an inner diameter of 18.97-19.13mm and an outer diameter of 21.97-22.47mm. The minimum vertical distance from the conduit 22 to the test plate fixture is 25.4 mm; it meets the requirements of...

Abstract

The invention discloses an automatic cyclic shakeout wear resistance testing device. The device comprises a square-frame-shaped overall support, a shakeout mechanism, a transmission mechanism and a control system. A lifting motor automatically carries a sand box filled with experimental sand to a funnel above the lifting motor, so that manpower for vertical conveying is saved, automatic dumping isperformed, automatic operation is realized in the whole process, the carrying mode of the experimental sand is changed, complicated manual sand loading operation is abandoned, full automation of theexperimental process is realized, the test efficiency is improved, and the labor cost is reduced. The experiment sand consumption is accurate, and an experiment result is objective and accurate; the experimental cycle index can be set as required, and the maximum cycle index of the wear resistance of a material can be obtained, thereby judging the wear resistance of the material.

Description

technical field [0001] The invention relates to a sand falling test device, in particular to an automatic cycle sand fall wear resistance test device. Background technique [0002] Photovoltaic module raw materials (backsheets, profiles) need to be subjected to a falling sand test to test the wear resistance of the surface coating under standard conditions, and the wear resistance of the coating on the test plate is represented by the amount of wear per unit film thickness. This test method complies with American Industrial Standard ASTM D968-83 and GB / T 23988-2009 standard. [0003] The existing falling sand wear-resistant testing device is to drop the experimental sand from a specified height onto the coated test plate through the conduit until the ground material of the test plate is exposed and visible. abrasion resistance of the coating. The shortcoming that existing device exists is as follows: [0004] First, according to the GB / T 23988-2009 standard for the determ...
