Technical Field

[0001] The present invention relates to the technical field of plastic box detection, and in particular to a detection device and method for plastic boxes. Background Art

[0002] Most of the packaging boxes for various items in life are made of plastic boxes. In order to ensure that the plastic boxes can effectively package the items, the plastic boxes need to have high drop resistance. Therefore, it is necessary to conduct random inspections on plastic boxes to test their drop resistance. The usual inspection method is to use a clamping mechanism to clamp the plastic box, raise it to a certain height, and then let it fall freely on the ground to check the degree of cracking of the plastic box to determine whether its drop resistance is qualified.

[0003] However, in actual use, the falling angle of the plastic box is random, and the above detection method can only detect the falling of the plastic box in several fixed directions, and cannot fully detect the drop resistance of the plastic box. Summary of the invention

[0004] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a detection device and method for a plastic box.

[0005] In order to achieve the above technical effects, the present invention adopts the following scheme:

[0007] According to a preferred technical solution, an infrared rangefinder is also provided at the upper end of the base, with the emitting end of the infrared rangefinder facing upward, located between the wrestling board and the supporting frame, the high end of the emitting end of the infrared rangefinder is flush with the height of the upper end surface of the wrestling board, and a horizontally arranged first cylinder is fixed on the lifting seat, and the telescopic rod of the first cylinder is fixedly connected to the mounting frame.

[0008] According to a preferred technical solution, the falling plate is detachably mounted on the base by bolts.

[0009] A preferred technical solution is that the lifting mechanism includes a vertical guide rail vertically arranged on the support frame, the lifting seat is matched and installed to slide on the vertical guide rail, and a rotating screw rod is also installed on the support frame. The screw rod is parallel to the vertical guide rail and passes through the lifting seat and is threadedly connected to the lifting seat, and one end of the screw rod is connected to a motor installed on the support frame.

[0010] A preferred technical solution is that the pneumatic clamp includes a horizontal slide rail horizontally arranged at the lower end of the mounting frame, two sliding blocks are slidably arranged on the horizontal slide rail, and clamping fingers are extended downward on the two sliding blocks. A second cylinder is fixed on the mounting frame, and the telescopic rod of the second cylinder extends downward between the two clamping fingers, and the telescopic rod of the second cylinder is hinged to the middle part of the two clamping fingers through two connecting rods, and a rotating rotating disk is provided on the inner side of the lower end of the two clamping fingers.

[0011] A method for detecting plastic boxes, firstly lowering a mounting frame by a lifting mechanism, clamping the plastic box by a pneumatic clamp, then the lifting mechanism drives the plastic box to rise to a set height, manually turning the plastic box to start rotating, randomly driving the pneumatic clamp to release the plastic box, allowing the plastic box to fall freely in a rotating state and fall on a falling plate at a random angle, checking the degree of cracking of the plastic box to determine whether it is qualified.

[0012] Compared with the prior art, the beneficial effects are:

[0013] The present invention has a simple structure and is easy to use. The pneumatic clamps the plastic box and raises it to a set height. After the plastic box is rotated, the plastic box is randomly released to fall. The plastic box falls randomly during rotation, so the angle at which it collides with the falling board is random, which can better simulate the falling state of the plastic box in actual use and better test the drop resistance of the plastic box.
