Description

Technical Field

[0003] The prior art (publication number: CN218994683U) discloses a drop test machine. The electric slide rail facilitates driving the moving rod to lift, thereby driving the placing plate to lift, facilitating the adjustment of the dropping height of the steel barrel. The rope winder facilitates the operation of winding and unwinding the lifting rope. After the electromagnet is energized, it generates an electromagnetic field. By the adsorption connection between the electromagnet and the iron sheet, it is convenient to limit the connection between the lifting rope and the placing plate. By the pulling force of the lifting rope, one end of the placing plate is fixed, making the placing plate in a horizontal state; when the electromagnet is powered off, the electromagnet loses the electromagnetic field and disconnects from the iron sheet, so that one end of the placing plate disconnects from the lifting rope. After passing through the rotating shaft, the rotated end of the placing plate freely drops downward, making the placing plate in a vertical state, so that the steel barrel on the placing plate freely drops. Therefore, when conducting the steel barrel drop test, it is convenient for the steel barrel to freely drop, the operation is convenient, and the working intensity of the staff is reduced.

[0004] In this prior art, the placing plate is driven to lift by the electric slide rail, and the lifting rope is wound and unwound by the rope winder; since the electric slide rail and the rope winder drive the placing plate and the lifting rope to move respectively, it is impossible to ensure that the placing plate is in a horizontal state, resulting in the carton sliding from the rotating plate and reducing the stability of the carton.

[0030] By fixing the support frame 11 on the bottom plate 10, rotatably connecting one end of the lead screw 12 to the bottom plate 10, and rotatably connecting the other end of the lead screw 12 to the support frame 11, the bottom plate 10 and the support frame 11 are cooperated to support the lead screw 12, so as to realize that the lead screw 12 can rotate in the support frame 11; by embedding one end of the lifting plate 13 into the support frame 11 and passing the lead screw 12 through the threaded hole of the lifting plate 13, the lead screw 12 is threadedly connected to the lifting plate 13, so as to realize that by rotating the lead screw 12, the lead screw 12 drives the lifting plate 13 to move up and down; by rotatably connecting one end of the rotating plate 14 to the other end of the lifting plate 13, the rotating plate 14 can rotate relative to the lifting plate 13. By fixing the wire reel holder 16 on the top of the support frame 11, embedding the wire reel 17 into the wire reel holder 16, and rotatably connecting the wire reel 17 to the wire reel holder 16, the wire reel holder 16 supports the wire reel 17, so as to realize that the wire reel 17 can rotate in the wire reel holder 16; by sleeving the first bevel gear 15 on the outside of the lead screw 12, connecting the second bevel gear 18 to the wire reel 17, and meshing the second bevel gear 18 with the first bevel gear 15, when the lead screw 12 rotates, the lead screw 12 drives the wire reel 17 to rotate through the first bevel gear 15 and the second bevel gear 18, so as to realize that the wire reel 17 rotates synchronously with the lead screw 12. By connecting one end of the suspension wire 19 to the wire reel 17 and winding the suspension wire 19 around the outside of the wire reel 17, when the wire reel 17 rotates, the wire reel 17 winds or unwinds the suspension wire 19; by connecting the other end of the suspension wire 19 to the electromagnet 20, installing the iron sheet 21 on the rotating plate 14, and fitting the iron sheet 21 to the electromagnet 20, when the electromagnet 20 is energized to generate a magnetic field, the suspension wire 19 drives the rotating plate 14 to move up and down through the electromagnet 20 and the iron sheet 21; by installing the impact-resistant panel 22 on the bottom plate 10 and making the impact-resistant panel 22 be located below the rotating plate 14, when the rotating plate 14 rotates downward, the cardboard box placed on the rotating plate 14 can fall onto the impact-resistant panel 22, so as to realize the impact resistance strength of the test cardboard box.

[0031] When specifically using the product, first energize the electromagnet 20 and make the electromagnet 20 fit with the iron sheet 21. At this time, since the suspension line 19 hoists the rotating plate 14 through the electromagnet 20, the rotating plate 14 is in a horizontal state. Then, place the cardboard box on the rotating plate 14. After that, rotate the lead screw 12, and the lead screw 12 drives the lifting plate 13 and the rotating plate 14 to move upward to a predetermined height. Since the first bevel gear 15 meshes with the second bevel gear 18, when the lead screw 12 rotates, the lead screw 12 will drive the wire reel 17 to rotate through the first bevel gear 15 and the second bevel gear 18, so that the wire reel 17 winds up the suspension line 19 to ensure that the rotating plate 14 is in a horizontal state. After that, de-energize the electromagnet 20, and the electromagnet 20 will not attract the iron sheet 21. Therefore, the rotating plate 14 will rotate downward due to gravity, so that the cardboard box placed on the rotating plate 14 will fall onto the impact-resistant panel 22, thereby testing the impact resistance strength of the cardboard box.

[0032] With the above structure, by sleeving the first bevel gear 15 on the outside of the lead screw 12, connecting the second bevel gear 18 to the wire reel 17, and meshing the first bevel gear 15 with the second bevel gear 18, when the lead screw 12 rotates, the lead screw 12 drives the wire reel 17 to rotate through the first bevel gear 15 and the second bevel gear 18, so as to realize the winding or unwinding of the suspension line 19 by the wire reel 17, and further realize the synchronous up and down movement of the rotating plate 14 and the lifting plate 13 to ensure that the rotating plate 14 is in a horizontal state, so as to avoid the situation that the cardboard box slides off the rotating plate 14 due to a certain angle of the rotating plate 14. At the same time, by meshing the first bevel gear 15 with the second bevel gear 18, it is realized that only one driving device can drive the lead screw 12 and the wire reel 17 to rotate simultaneously, thereby saving at least one driving device and reducing the production cost of the product.
