Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, specifically to a pressure detection device for corrugated cardboard boxes. Background Technology

[0002] Corrugated cardboard boxes are paper products commonly used in packaging and logistics. After the corrugated cardboard boxes are processed and produced, it is necessary to randomly select a batch of corrugated cardboard boxes for pressure testing to determine whether the corrugated cardboard boxes meet the design pressure resistance requirements, and at the same time to control the quality of the corrugated cardboard box processing.

[0003] When performing pressure tests on corrugated cardboard boxes, if the boxes are not fully unfolded, the pressure cannot be evenly distributed to the surrounding support surfaces through the three-dimensional structure. Instead, the pressure is concentrated at the contact points of the folded layers or the unfurled corrugated columns. This results in the test results only reflecting the bending resistance of the flat cardboard, rather than the three-dimensional compressive strength of the finished cardboard box. Therefore, there is an urgent need to develop a pressure testing device for corrugated cardboard boxes to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a corrugated cardboard box pressure detection device, thus solving the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides a corrugated cardboard box pressure detection device through the following technical solution: a box body, a pressure detection component is provided on the top of the box body, and a housing is fixedly installed at the bottom inside the box body.

[0006] It also includes a negative pressure holding mechanism, which includes a motor located at the bottom of the housing. The motor output end passes through the bottom of the housing and is fixed to a gear plate. The gear plate is located at the center of the bottom inside the housing. Limiting posts are provided on both sides inside the housing, and the limiting posts are located on both sides of the gear plate. A rack is movably installed on the outside of the limiting posts, and the rack has a limiting groove that slides with the limiting posts. The rack meshes with the gear plate. One end of the rack passes through the top of the housing and is fixed to a horizontal plate. A telescopic adjustment component is movably installed on the top of the horizontal plate. A mounting plate is fixedly installed on one side of the telescopic adjustment component, and two sets of suction cups are fixedly installed on one side of the mounting plate.

[0007] Preferably, the rack has an L-shaped profile.

[0008] Preferably, a protective box is fixedly installed at the center of the bottom of the housing, and the protective box is located outside the motor.

[0009] Preferably, the motor is a servo motor.

[0010] Preferably, the pressure detection assembly includes an electric rod located at the center of the top of the housing, with the output end of the electric rod penetrating through the top of the housing and fixedly connected to a pressure sensor, and a pressure plate fixedly connected to the bottom of the pressure sensor.

[0011] Preferably, the bottom of the pressure plate is provided with an abutment groove, and the abutment groove is rectangular in shape.

[0012] Preferably, the telescopic adjustment assembly includes multiple sets of movable seats disposed on the top of the horizontal plate, with the bottom end of the movable seats extending into the interior of the horizontal plate and slidingly engaging with the inner wall of the horizontal plate.

Detailed Implementation

[0024] 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 protection scope of the present utility model.

[0025] First implementation method:

[0026] refer to Figure 1-7 A pressure testing device for corrugated cardboard boxes includes a box body 1, a pressure testing component is provided on the top of the box body 1, and a housing 2 is fixedly installed on the bottom of the inner side of the box body 1.

[0027] It also includes a negative pressure holding mechanism 3, which includes a motor 306 located at the bottom of the housing 2. The output end of the motor 306 passes through the bottom of the housing 2 and fixes a gear plate 301. The gear plate 301 is located at the center of the bottom inside the housing 2. Limiting posts 302 are provided on both sides inside the housing 2, and the limiting posts 302 are located on both sides of the gear plate 301. A rack 303 is movably installed on the outside of the limiting posts 302, and a limiting groove is opened inside the rack 303 to slide with the limiting posts 302. The rack 303 meshes with the gear plate 301. One end of the rack 303 passes through the top of the housing 2 and is fixed to a horizontal plate 304. A telescopic adjustment component is movably installed on the top of the horizontal plate 304. An installation plate 403 is fixedly installed on one side of the telescopic adjustment component, and two sets of suction cups 305 are fixedly installed on one side of the installation plate 403.

[0028] The rack 303 is L-shaped, and a protective box 307 is fixedly installed at the center of the bottom of the housing 2. The protective box 307 is located outside the motor 306, which is a servo motor.

[0029] The pressure detection assembly includes an electric rod 101 located at the center of the top of the housing 1. The output end of the electric rod 101 passes through the top of the housing 1 and is fixedly connected to a pressure sensor 102. A pressure plate 103 is fixedly connected to the bottom of the pressure sensor 102. A contact groove 5 is provided at the bottom of the pressure plate 103, and the contact groove 5 is rectangular in shape.

[0030] First, after the operator places the corrugated cardboard box to be tested at the bottom of the housing 2, the electric rod 101 moves and drives the pressure sensor 102 to move vertically. The vertically moving pressure sensor 102 drives the pressure plate 103 to apply pressure to the top of the corrugated cardboard box, and limits the top of the corrugated cardboard box through the contact groove 5 to prevent the corrugated cardboard box from moving. The pressure sensor 102, in conjunction with the controller, can detect the pressure value applied to the top of the cardboard box, so that the operator can understand the pressure value on the top of the corrugated cardboard box through the controller.

[0031] The motor 306 drives the gear disk 301 to rotate in the forward direction. The rotating gear disk 301 drives the two sets of meshing racks 303 to move. The moving racks 303 are limited by the limiting post 302, so that the two sets of racks 303 move horizontally. The moving racks 303 drive the horizontal plate 304 to move synchronously. The moving horizontal plate 304 drives the suction cup 305 to move to the outside of the corrugated cardboard box and abut against it, so that the suction cup 305 adsorbs the outside of the corrugated cardboard box with negative pressure.

[0032] Motor 306 drives toothed disc 301 to rotate in the opposite direction. The rotating toothed disc 301 drives rack 303 to move in the opposite position. The rack 303, which moves in the opposite position, can drive suction cup 305 to move away from each other through cross plate 304, thereby unfolding the corrugated carton and realizing the function of automatically unfolding the corrugated carton to be unfolded.

[0033] This avoids the problem that when pressure is tested on the top of an unfurled corrugated cardboard box, the pressure cannot be evenly distributed to the surrounding support surfaces through the three-dimensional structure of the corrugated cardboard box. Instead, the pressure is concentrated at the contact points of the folded layers or the unfurled corrugated columns, causing the test results to only reflect the bending resistance of the flat cardboard, rather than the three-dimensional compressive strength of the finished corrugated cardboard box.

[0034] Second implementation method:

[0035] When inspecting corrugated boxes of different specifications, it is necessary to use a variety of matching limiting structures to perform pressure testing on the corrugated boxes.

[0036] refer to Figure 3-6 In the second embodiment of this utility model, the telescopic adjustment component includes multiple sets of movable seats 4 disposed on the top of the horizontal plate 304, and the bottom end of the movable seat 4 extends into the interior of the horizontal plate 304 and slides in cooperation with the inner wall of the horizontal plate 304. The top of the movable seat 4 is fixedly connected to the support rod 401, and two sets of sliding sleeve seats 402 are movably installed on the outside of the support rod 401. One side of the sliding sleeve seat 402 is fixedly connected to one side of the mounting plate 403. A locking member 404 is threadedly installed on one side of the top of the movable seat 4. There are at least two sets of movable seats 4, and the two sets of movable seats 4 are horizontally aligned.

[0037] The operator can adjust the distance between the two sets of support rods 401 by pulling the movable seat 4, so that the suction cup 305 can adapt to the negative pressure adsorption of corrugated cardboard boxes of different widths. Then, rotating the locking part 404 can fix the moving position of the movable seat 4. The operator can push the sliding sleeve seat 402 to move vertically outside the support rod 401, so that the suction cup 305 can adapt to the negative pressure adsorption of corrugated cardboard boxes of different heights. This realizes the function of adjusting the negative pressure adsorption range of the device, which makes it easy to adjust the position of the suction cup 305 according to the corrugated cardboard boxes of different specifications. This solves the problem of needing to use a matching limiting and fixing structure when changing to test corrugated cardboard boxes of different specifications.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
