Description

Technical Field

[0001] This utility model relates to the field of cardboard box compression testing technology, and specifically to a cardboard box compression testing machine. Background Technology

[0002] As the main carrier of logistics packaging, the compression resistance of cardboard boxes directly affects the safety of goods during transportation.

[0003] Currently, there are some cardboard box compression testing devices on the market. These devices typically use relatively simple testing methods. Generally, the cardboard box is placed on a testing platform, and then pressure is applied to the box using a simple indenter. At the same time, pressure sensors record the pressure data to evaluate the compression resistance of the cardboard box.

[0004] However, existing technologies have many shortcomings. First, existing equipment cannot simulate the actual stress conditions of cardboard boxes during actual transportation. In actual transportation, cardboard boxes are often subjected to forces from multiple directions, such as compression and collisions from surrounding goods or packaging. Existing equipment only applies pressure through a single pressure head, which cannot comprehensively and realistically reflect the stress state of cardboard boxes in complex transportation environments, resulting in a large deviation between test results and actual conditions. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned shortcomings and provide a carton compression testing machine. This machine places the carton to be tested on a base plate and precisely arranges auxiliary cartons around it, securing them firmly with side plates. This simulates the complex and varied stress environment experienced by the carton during actual transportation. Simultaneously, a second servo motor precisely controls a second ball screw to drive the top frame and pressure plate downwards smoothly. Combined with a high-precision pressure sensor, real-time compression testing is performed. This solves the technical problem of existing technologies failing to simulate the actual stress conditions of cartons during transportation, resulting in large deviations between test results and actual values.

[0006] The objective of this utility model is achieved through the following means:

[0007] A cardboard box compression testing machine includes a base plate. Uprights are fixed to both sides of the upper end of the base plate with screws. A top strip is fixed to the inner side of the upper end of each upright with screws. A second sliding groove is formed on the inner side of the upright. A second servo motor is mounted on the lower end of the second sliding groove via an inner frame. A second ball screw is fixed to the output end of the second servo motor. A second slider is externally connected to the second ball screw and slidably connected to the second sliding groove. A top frame is fixed to the outside of the second slider with screws. A pressure sensor is fixedly installed at the middle of the lower end face of the top frame. A pressure plate is installed at the lower end of the pressure sensor. First sliding grooves arranged in a cross pattern are formed inside the upper end of the base plate. First servo motors are mounted inside each of the four first sliding grooves via an inner frame. A first ball screw is fixed to the output end of each first servo motor. A first slider is externally connected to the first ball screw and slidably connected to the first sliding groove. A side frame is fixed to the upper end of the first slider with screws. A side plate is installed on the inner side of the side frame.

[0008] Furthermore, each of the four corners of the upper end face of the pressure plate is fixed with a sliding rod by screws, and the sliding rod is slidably connected to the top frame.

[0009] Furthermore, an anti-slip strip is installed on the inner side of the side panel, and the anti-slip strip is adhered and fixed to the side panel. The anti-slip strip is used to improve the anti-slip performance of the side panel.

[0010] Furthermore, a touch control screen is installed on the outer side of the stand, and the touch control screen is connected to the stand via a fixing bracket. The touch control screen is used to display test data and control the operation of the machine.

[0011] Furthermore, an emergency stop button is installed on the outer side of the touch control screen, and the emergency stop button is fixed to the touch control screen with screws. The emergency stop button is used to stop the equipment in an emergency.

[0012] Furthermore, a crossbeam is fixed to the front end of the upright frame with screws, and a safety light curtain is installed at the front end of the crossbeam. The safety light curtain is used to monitor the operating area in real time.

[0013] The beneficial effects of this utility model are as follows: by placing the cardboard box on the top of the base plate, placing four auxiliary cardboard boxes around the cardboard box, and fixing the four auxiliary cardboard boxes around the cardboard box with side plates, the complex and variable stress environment of the cardboard box during actual transportation can be simulated. In conjunction with the second servo motor controlling the second ball screw, the second slider is controlled to drive the top frame and pressure plate to press down. Combined with the pressure sensor for pressure resistance testing, the repeatability and reliability of the test results are improved. Attached Figure Description

A top strip 3 is fixed to the inner side of the upper end of the uprights 2 by screws. A second slide groove 11 is formed on the inner side of the uprights 2. A second servo motor 12 is mounted on the lower end of the second slide groove 11 via an inner frame. A second ball screw 13 is fixed to the output end of the second servo motor 12. A second slider 14 is externally connected to the second ball screw 13, and the second slider 14 is slidably connected to the second slide groove 11. The outer side of the second slider 14 is fixed with screws. A pressure sensor 17 is fixedly installed at the middle of the lower end face of the top frame 15. A pressure plate 16 is installed at the lower end of the pressure sensor 17. The upper end of the base plate 1 has a first sliding groove 4 arranged in a cross pattern. The interior of each of the four first sliding grooves 4 is equipped with a first servo motor 5 through an inner frame. The output end of the first servo motor 5 is fixed with a first ball screw 6. The first ball screw 6 is externally connected to a first slider 7, and the first slider 7 is slidably connected to the first sliding groove 4. The upper end of the first slider 7 is fixed with a side frame 8 by screws. A side plate 9 is installed on the inner side of the side frame 8.

[0020] like Figure 1 and Figure 2 As shown, slide rods 18 are fixed to the four corners of the upper end face of the pressure plate 16 by screws, and the slide rods 18 are slidably connected to the top frame 15.

[0021] like Figure 1 and Figure 3As shown, an anti-slip strip 10 is installed on the inner side of the side panel 9, and the anti-slip strip 10 is adhered and fixed to the side panel 9. The anti-slip strip 10 is used to improve the anti-slip performance of the side panel 9.

[0025] The working process of the cardboard box compression tester in this embodiment is as follows: The cardboard box to be tested is placed on the top of the base plate 1. Then, four auxiliary cardboard boxes of appropriate size are placed around the cardboard box (to simulate the actual stacking environment and ensure that the cardboard box to be tested is subjected to uniform force around its perimeter). The four first servo motors 5 are controlled to rotate the first ball screws 6, thereby driving the first slider 7 to drive the side frame 8, which in turn causes the side plate 9 to push the four external cardboard boxes to clamp the cardboard box to be tested. When the side plate 9 contacts the auxiliary cardboard boxes, the clamping force is ensured to be moderate to avoid excessive compression that could deform the auxiliary cardboard boxes and affect the test. To test accuracy, the second servo motor 12 is then activated to control the second ball screw 13. The rotation of the second ball screw 13, in conjunction with the second slide groove 11, causes the second slider 14 to descend.
