Description

Technical Field

[0001] This utility model relates to the field of cardboard box testing technology, and in particular to a cardboard box compression resistance testing device. Background Technology

[0002] Carton compression testing is a crucial test for evaluating the ability of packaging boxes to withstand vertical pressure during stacking or transportation, directly impacting product transport safety and storage stability. This test simulates the deformation resistance of cartons under static or dynamic pressure to determine their maximum compressive strength. The testing principle involves applying uniform pressure to the carton using a compression testing machine, recording the critical load at collapse, and simultaneously monitoring the deformation curve to analyze the carton's compressive strength and structural stability.

[0003] Existing cardboard box compression testing devices require operators to manually calibrate the box and place it in the center of the testing platform. A hydraulic telescopic rod then drives the upper pressure plate to descend and compress the box, with the pressure change displayed directly on the controller. However, current testing typically involves pressing the box face-up from the top, which is insufficient in real-world use as items on top are not always perfectly flat against the surface. Therefore, an offset compression test should be performed to increase the comprehensiveness of the data. However, the limited size of the existing testing platform prevents this from being implemented. Furthermore, the box height needs to be manually measured before testing, resulting in low efficiency. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a carton compression testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a carton compression testing device, comprising a base plate, two vertical rods fixed to the side of the upper surface of the base plate, a top plate fixedly connected to the top ends of the two vertical rods, a hydraulic telescopic rod fixed to the middle of the upper surface of the top plate, the bottom telescopic end of the hydraulic telescopic rod passing through the top plate and fixedly connected to a drive plate, a pressure sensor fixed to the middle of the lower surface of the drive plate, a pressure plate fixedly connected to the lower surface of the pressure sensor, a distance sensor fixed to the side of the lower surface of the drive plate, a controller fixedly installed on the upper surface of the top plate, a base fixed to the upper surface of the base plate and below the pressure plate, the base having a T-shaped side profile, a C-shaped slide block slidably connected to the surface of the base, two symmetrical compression components fixed to the upper surface of the slide block, a through hole opened on the side of the slide block, a positioning component slidably connected inside the through hole, and a first insertion hole and a second insertion hole for engaging the positioning component respectively opened in the middle and on the side of the upper surface of the base.

[0006] Furthermore, the extrusion assembly includes a vertical plate fixed to the upper surface of the slide block, a spring fixed to the side of the vertical plate near the center of the slide block, a clamping plate fixed to the other end of the spring, and the top of the clamping plate is designed to be inclined and bent.

[0007] Furthermore, a guide rod is fixed to the side of the clamping plate near the vertical plate, and the guide rod passes through the vertical plate and is slidably connected to the vertical plate.

[0008] Furthermore, the positioning component includes a rod that is slidably connected to the through hole, an end plate fixed to the top of the rod, and a tension spring fixedly connected to the lower surface of the end plate and the upper surface of the slide block.

[0009] Furthermore, a handle is fixed to the upper surface of the slide near the positioning component.

[0010] Furthermore, the pressure sensor, distance sensor, and hydraulic telescopic rod are all electrically connected to the controller.

[0011] Furthermore, the pressure plate has a notch located below the distance sensor.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, this utility model is a cardboard box compression testing device, which includes a hydraulic telescopic rod, a drive plate, a pressure sensor, a pressure plate, a base, a slide, and a compression assembly. The compression assembly quickly fixes the cardboard box at the center of the slide surface. The hydraulic telescopic rod drives the drive plate and pressure plate to descend, thereby detecting the compression of the cardboard box. The pressure sensor monitors the pressure in real time. The horizontal movement of the slide along the base changes the position of the cardboard box relative to the pressure plate, thereby using the pressure plate to perform offset compression on the cardboard box. This detects the compression resistance of the cardboard box when it is not compressed from the front, thus providing more reference data and making the cardboard box testing more comprehensive.

[0014] 2. When in use, this utility model is a cardboard box compression testing device, which is equipped with a drive plate and a distance sensor. The distance sensor measures the distance from the drive plate to the upper surface of the cardboard box. The initial height of the drive plate minus this distance is the height of the cardboard box. It eliminates the need to manually measure the height of the cardboard box with a tape measure before measurement, thus simplifying the testing steps and improving work efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] like Figures 1-3 As shown, a carton compression testing device is disclosed, comprising a base plate 1, two vertical rods 2 fixed to the side of the upper surface of the base plate 1, a top plate 3 fixedly connected to the top ends of the two vertical rods 2, a hydraulic telescopic rod 4 fixed to the middle of the upper surface of the top plate 3, the bottom telescopic end of the hydraulic telescopic rod 4 passing through the top plate 3 and fixedly connected to a drive plate 5, a pressure sensor 6 fixed to the middle of the lower surface of the drive plate 5, a pressure plate 7 fixedly connected to the lower surface of the pressure sensor 6, a distance sensor 8 fixed to the side of the lower surface of the drive plate 5, a controller 9 fixedly installed on the upper surface of the top plate 3, a base 10 fixed to the upper surface of the base plate 1 and below the pressure plate 7, the base 10 having a T-shaped side profile, a C-shaped slide block 11 slidably connected to the surface of the base 10, two symmetrical compression components 12 fixed to the upper surface of the slide block 11, a through hole 111 opened on the side of the slide block 11, a positioning component 13 slidably connected inside the through hole 111, and a first insertion hole 101 and a second insertion hole 102 for engaging the positioning component 13 respectively opened on the middle and side of the upper surface of the base 10.

[0023] In this embodiment, the hydraulic telescopic rod 4 is a Bosch Rexroth CDM125 / 12-50, the distance sensor 8 is a KEYENCE IL-1000 laser sensor, the pressure sensor 6 is an S-type LC103B sensor, and the controller 9 is a Siemens SIMATIC S7-1200 / S7-1500 controller with a display screen. The hydraulic telescopic rod 4, pressure sensor 6, and controller 9 are the same models used in existing carton compression machines, but are not limited to the aforementioned models.

[0024] The extrusion assembly 12 includes a vertical plate 121 fixed to the upper surface of the slide block 11. A spring 122 is fixed to the side of the vertical plate 121 near the center of the slide block 11. A clamping plate 123 is fixed to the other end of the spring 122, and the top of the clamping plate 123 is designed to be inclined and bent.

[0025] When placing the cardboard box, insert the cardboard box between the clamps 123 of the two compression components 12. The inclined surface at the top of the clamps 123 serves as a guide. Under the compression force of the spring 122, the cardboard box is fixed at the center position of the upper surface of the slide block 11.

[0026] A guide rod 124 is fixed to the side of the clamping plate 123 near the vertical plate 121. The guide rod 124 passes through the vertical plate 121 and is slidably connected to the vertical plate 121.

[0027] The guide rod 124 provides support and guidance for the clamping plate 123.

[0028] The positioning assembly 13 includes a rod 131 that is slidably connected to the through hole 111. An end plate 132 is fixed to the top of the rod 131. A tension spring 133 is fixedly connected to the lower surface of the end plate 132 and the upper surface of the slide block 11.

[0029] The slide 11 can slide along the surface of the T-shaped base 10, thereby changing the position of the slide 11 relative to the pressure plate 7. When the slide 11 is directly below the pressure plate 7, the insert rod 131 is inserted into the first insertion hole 101, and the slide 11 is fixed below the pressure plate 7. When an offset compression test is required, the end plate 132 is pulled to separate the insert rod 131 from the first insertion hole 101, and then the slide 11 is moved to the side of the base 10. Then the end plate 132 is released, and under the downward pulling action of the tension spring 133, the insert rod 131 is inserted into the second insertion hole 102, thereby achieving the positional offset between the slide 11 and the pressure plate 7. When the pressure plate 7 descends and squeezes the carton on the surface of the slide 11, it is the offset compression test.

[0030] A handle 14 is fixed on the upper surface of the slide 11 near the positioning component 13.

[0031] Pressure sensor 6, distance sensor 8, and hydraulic telescopic rod 4 are all electrically connected to controller 9.

[0032] The controller 9 can comprehensively control the operation of the pressure sensor 6, the distance sensor 8, and the hydraulic telescopic rod 4. When the hydraulic telescopic rod 4 drives the drive plate 5 to descend, the pressure plate 7 squeezes the upper surface of the carton. The pressure sensor 6 will monitor the pressure value in real time. The pressure value is displayed on the display of the controller 9 in real time and presented as a pressure curve.

[0033] The pressure plate 7 is located below the distance sensor 8 and has a notch 71.

[0034] When a carton is placed on the upper surface of the slide block 11, the light from the distance sensor 8 passes through the notch 71 to measure the distance r from the drive board 5 to the upper surface of the carton. The initial height of the drive board 5 built into the controller 9 is h. After processing by the internal processor of the controller 9, the height of the carton a = hr, thus directly obtaining the height of the carton.

[0035] Working principle: The carton is placed on the surface of the slide 11, and the extrusion assembly 12 presses and fixes the carton. Then, the controller 9 controls the hydraulic telescopic rod 4 to drive the drive plate 5 to descend, and the pressure plate 7 presses the carton. The pressure sensor 6 monitors the pressure value in real time, and the pressure value is displayed on the display of the controller 9 in real time as a pressure curve. If an offset extrusion test is required, after fixing the carton, the slide 11 needs to be moved to the side of the base 10, so that the carton is offset from the pressure plate 7, and then the hydraulic telescopic rod 4 is activated to drive the pressure plate 7 to descend and extrude the carton for the extrusion test.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
