The screw rod is started, the sliding block 131 moves to the position above the feed hopper 140 along the sliding rail 130, the telescopic rod 133 extends, the clamping jaw moves downwards to the feed hopper 140 to clamp a plastic pipe sample to be detected, and the plastic pipe sample moves upwards along with the shortening of the telescopic rod 133. And starting the screw rod again, moving the sliding block 131 to the upper part of the conveying belt 110 along the sliding rail 130, extending the telescopic rod 133, moving the clamping jaw downwards to the upper part of the conveying belt 110 and placing the plastic pipe sample to be detected on the supporting seat.
The conveyor belt 110 and impact assembly are activated. The conveying belt 110 is in an intermittent moving state under the action of the intermittent divider, when the conveying belt 110 stops, the plastic pipe sample to be detected is positioned below the impact block 125, the power supply of the electromagnet seat 120 is turned off, and the mounting seat 122 and the impact block 125 fall downwards; completing the impact test of the plastic pipe sample; then the electromagnet seat 120 drives the mounting seat 122 and the impact block 125 to move upwards and return to the original position under the action of the first driving piece 123; the conveyer belt 110 continues to move until the next plastic pipe sample to be tested is located below the impact block 125, the conveyer belt 110 stops moving, and the impact test is started.
After the plastic pipe sample subjected to the impact test moves to the edge along with the conveying belt 110, the plastic pipe sample automatically drops to the discharge port 102 from the conveying belt 110 along with the change of the moving direction of the conveying belt 110 and is discharged from the discharge port 102.
The plastic pipe impact resistance detection device convenient to maintain provided by the invention can complete impact tests of a plurality of plastic pipe samples at one time, can realize one-time startup and shutdown of a group of tests, is simple to operate and convenient to use, saves time and labor, and improves the detection efficiency.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
