Description

Technical Field

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

[0002] Packaging boxes play a vital role in protecting the products inside during transportation. They are typically stacked in multiple layers to save space and facilitate transshipment, thus requiring a certain level of pressure resistance. However, existing packaging box pressure testing machines suffer from limitations in precision, leading to risks of uneven stress distribution and inaccurate pressure readings. Utility Model Content

[0003] To address the aforementioned deficiencies in existing technologies, this utility model provides a packaging box pressure testing machine, the specific technical solution of which is as follows: A packaging box pressure testing machine includes a base, a packaging box support platform, support frames, a servo motor, a grid-shaped lifting block, a pressure sensor, connecting rods, and a test plate. The packaging box support platform is installed on top of the base, and support frames are installed on the left and right sides of the packaging box support platform. The left and right ends of the grid-shaped lifting block are slidably connected to the left and right support frames, respectively. The servo motor is installed inside the base and drives the grid-shaped lifting block to move up and down. A pressure sensor is installed at the center of the grid-shaped lifting block, and connecting rods are installed at the front and rear four corners of the grid-shaped lifting block. The lower end of the connecting rods is connected to the test plate. The detection end of the pressure sensor abuts against the test plate, and the test plate is located directly above the packaging box support platform and between the two support frames.

[0004] In a preferred embodiment of this utility model, the servo motor drives the reducer to start, the reducer output shaft is connected to the right lead screw, the right lead screw is connected to the left lead screw through chain transmission, the left and right lead screws are respectively installed in the left and right support frames, the left and right lead screws are respectively threaded with nuts, the nuts are installed in the guide block, and the guide block is connected to the grid-shaped lifting block.

[0005] As a preferred embodiment of this utility model, each support frame is vertically installed with guide columns on the front and rear sides, and the guide columns are slidably connected to guide blocks, which are located inside the support frame.

[0006] As a preferred embodiment of this utility model, the support frame is provided with a clearance groove extending from top to bottom, and the grid-shaped lifting block extends into the clearance groove.

[0007] As a preferred embodiment of this utility model, a control box is also installed above the base.

[0008] Beneficial effects: When this packaging box pressure testing machine is working, the test plate is in a high position. The packaging box to be tested is placed on the packaging box support platform. The servo motor drives the grid-shaped lifting block to descend. The grid-shaped lifting block drives the test plate to descend smoothly through the connecting rods at the four corners. When the pressure sensor detects that the set pressure value has been reached, the test plate presses the packaging box for a period of time. The packaging box is observed to see if it is deformed. The packaging box is subjected to uniform force. The pressure sensor is located at the center of the grid-shaped lifting block, resulting in high pressure detection accuracy.
