Description

Technical Field

[0001] This utility model relates to the field of testing machines, specifically to a packaging box drop testing machine. Background Technology

[0002] A drop tester is a machine that simulates drop scenarios during product transportation. It is specifically designed to test the damage to product packaging from falls and to assess its impact resistance during transport and handling. Existing drop testers for packaging boxes have the following drawbacks: there is a certain risk of the box falling during the process of being raised to the set height, which can prevent the test from proceeding normally. Furthermore, when simulating a natural drop, the lifting plate may not descend precisely into the drop floor, potentially hindering the box's natural fall. Utility Model Content

[0003] To address the aforementioned shortcomings of existing technologies, the technical problem this invention aims to solve is how to improve the stability of a packaging box drop testing machine during packaging box drop tests. The specific technical solution is as follows: A drop test machine for packaging boxes includes a drop floor, a column, a lifting frame, an E-shaped fork, a hook block, a lifting plate, a locking mechanism, a nut, a lead screw, a motor, a clamping connection assembly, and a triangular plate. The column is installed at the rear upper part of the drop floor, and the lifting frame is installed inside the column. The E-shaped fork is installed at the front of the lifting frame. An E-shaped groove that mates with the E-shaped fork is provided at the front upper part of the drop floor. The hook block is installed on the top of the lifting frame. The lifting plate is locked to the hook block by the locking mechanism. A nut is installed in the lifting plate, and the nut is threadedly connected to the lead screw. A motor is installed on the top of the column, and the motor drives the lead screw to rotate. A triangular plate is connected to the front of the lifting plate through the clamping connection assembly. The triangular plate is used to clamp the packaging box placed on the E-shaped fork.

[0004] As a preferred embodiment of this utility model, the lifting frame includes a left side plate, a right side plate, a top plate, and a middle connecting rod. The left side plate is separated from the right side plate. A top plate is installed above the left side plate and the right side plate. A hook-shaped block is installed above the top plate. Four middle connecting rods are installed between the left side plate and the right side plate. Rollers are installed at the left and right ends of each middle connecting rod. The rollers slide in contact with a roller shaft, which extends vertically upward. E-shaped forks are installed in front of the left side plate and the right side plate.

[0005] As a preferred embodiment of this utility model, a buffer is installed on the top of the top plate.

[0006] As a preferred embodiment of this utility model, the locking mechanism includes a locking rod, a front and rear moving rod, a sleeve plate, a spring, a cylinder, and a locking plate. The locking rod is installed between two front and rear moving rods, which are movably fitted in the sleeve plate. A spring is fitted behind the front and rear moving rods, with the front end of the spring pressing against the front and rear moving rods and the rear end pressing against the locking plate. The cylinder drives the locking plate to move, and the hook-shaped block is provided with a hook-shaped groove for the locking rod to engage.

[0007] As a preferred embodiment of this utility model, two cylinders are installed above the lifting plate, and a sleeve plate is installed in the middle position above the lifting plate, with the two cylinders located on the left and right sides of the sleeve plate.

[0008] As a preferred embodiment of this utility model, the clamping connection assembly includes an extension arm, a rod mounting block, a first mounting rod, a first clamping block, a profile, a second clamping block, and a second mounting rod. The extension arm is installed in front of the lifting plate, the rod mounting block is installed in front of the extension arm, the first mounting rod is installed on the rod mounting block, the first mounting rod is vertically upward, the first clamping block is installed on the first mounting rod, the profile is installed in front of the first clamping block, the profile extends forward, the second clamping block is installed in the profile, the second mounting rod is installed on the second clamping block, and a triangular plate is installed at the bottom of the second mounting rod.

[0009] Beneficial effects: When this packaging box drop test machine is working, the packaging box is placed on the drop floor and on the E-shaped fork. The triangular plate clamps the packaging box from above. The lifting plate is locked with the hook block by a locking mechanism. The motor drives the lifting plate to rise. After the lifting plate drives the lifting frame and the E-shaped fork to rise to the specified height, the locking mechanism unlocks the hook block. The packaging box falls naturally to the drop floor as the E-shaped fork descends, which well simulates the drop scenario. During the rising process, the triangular plate clamps the packaging box from above to ensure that it will not fall accidentally. After the E-shaped fork descends, it will extend into the E-shaped groove without obstructing the packaging box. The test process is stable and reliable and meets the test requirements.
