Description

Technical Field

[0001] The utility model belongs to the technical field of testing devices, and in particular relates to a compression-resistant paper pit box testing device. Background Art

[0002] The corrugated box is a packaging box made by gluing cardboard and corrugated paper. It is suitable for some heavy and fragile products in the power supply industry, toy industry, electrical appliance industry, lighting industry, and smart home industry. For example, products such as mobile power supplies can be packaged with corrugated boxes.

[0003] Usually, the hardness and compressive strength of paper corrugated boxes need to be tested after production. The current method is to press the paper box manually. If the paper box is soft or the finger can be pressed directly, it means that the hardness is relatively low. However, the manual test of pressing the corrugated box is uneven, so it is difficult to accurately determine the compressive strength of the corrugated box, and it is not conducive to testing relatively large corrugated boxes, which may lead to inaccurate test results.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0029] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0031] See also Figure 2 , Figure 4 As shown, the utility model is a compression-resistant paper pit box testing device, comprising a support platform 1, a first support assembly 2 is arranged on the top of the support platform 1, a second support assembly 3 is slidably mounted on the top of the support platform 1, a test platform 4 is fixedly mounted on the outer surface of the first support assembly 2, an auxiliary support assembly 5 is fixedly mounted on the outer surface of the second support assembly 3, an elastic clamping mechanism 6 is arranged on one side of the first support assembly 2 and the second support assembly 3, and a driving device 7 is arranged on the top of the first support assembly 2;

[0032] A rotating sleeve 8 is rotatably mounted on the output end of the driving device 7, a chassis 9 is fixedly mounted on the bottom of the driving device 7, a pushing assembly 10 is rotatably mounted on the bottom of the rotating sleeve 8, a pressing block 11 is fixedly mounted on the bottom of the pushing assembly 10, a central pressing block 12 is fixedly mounted on the bottom of the chassis 9, and the bottom of the pushing assembly 10 is slidably connected to the top of the chassis 9.

[0033] When in use, the paper pit box to be tested is placed on the top of the test bench 4. Before testing it, the second support component 3 is pushed to make it slide on the top of the support platform 1 and gradually approach the first support component 2, and the elastic clamping mechanism 6 is squeezed in the reverse direction to compress it, until the auxiliary support component 5 outside the second support component 3 is attached and gradually extends to the bottom of the test bench 4 so that the two sets of elastic clamping mechanisms 6 are close to and clamped on both sides of the pit box. Then the second support component 3 stops moving, and the driving device 7 is started at this time to drive the rotating sleeve 8 and the chassis 9 at the bottom to move downward, and at the same time, the rotating sleeve 8 is rotated to drive the pushing component 10 to rotate and generate a sliding displacement on the top of the chassis 9, thereby driving the pressure block 11 to expand outward along the inner side of the chassis 9. At this time, the chassis 9 is driven by the driving device 7 to continue to descend, so that the pressure block 11 and the center pressure block 12 are in contact with the top of the pit box to generate pressure, and the compressive strength test begins.

[0034] The utility model arranges a first support assembly 2 and a second support assembly 3 on the top of the support platform 1, so that the first support assembly 2 and the second support assembly 3 can cooperate to provide different support spacings according to pit boxes of different specifications, and at the same time, the auxiliary support assembly 5 can cooperate to provide auxiliary support at the bottom of the test platform 4. When the driving device 7 drives the pressure block 11 to descend and generates pressure on the pit box, the compressive support effect of the test platform 4 is better. While the driving device 7 drives the chassis 9 and the pressure block 11 to descend and generate pressure, the rotating sleeve 8 drives the pushing assembly 10 to push the pressure block 11 to move so that it can expand or contract and cooperate with the central pressure block 12 to generate pressure, so that the pressure test points at different positions can be changed according to the specifications of the pit box, so that the surface of the pit box can be evenly stressed.

[0035] In one embodiment, for the above-mentioned first support assembly 2, the first support assembly 2 includes a first support column 201, a top seat 202 is fixedly installed on the top of the first support column 201, a top plate 203 is fixedly installed inside the top seat 202, and the driving device 7 is fixedly connected to the top of the top plate 203.

[0036] By arranging a top seat 202 and a top plate 203 on the top of the first support column 201 , it is convenient to provide a positioning support function for the driving device 7 , and at the same time, it is convenient to provide an auxiliary connection function for the second support assembly 3 .

[0037] In one embodiment, for the above-mentioned first support column 201, a horizontal plate 204 is fixedly installed on the inner wall of the first support column 201, and the second support assembly 3 includes a second support column 301, and a slider 302 is fixedly installed on the bottom of the second support column 301, and the second support column 301 respectively penetrates the outer surfaces of the top plate 203 and the horizontal plate 204 and is slidably connected thereto.

[0038] The middle section and the top of the second support column 301 pass through the horizontal plate 204 and the top plate 203 respectively. When the second support column 301 is pushed to move toward the first support column 201, the bottom slider 302 slides on the support platform 1. The cooperation between the horizontal plate 204 and the top plate 203 can provide lateral sliding support and limiting effect for the second support column 301, so that it can accurately move in the direction opposite to the first support column 201, so as to provide accurate clamping effect for the pit box.

[0039] In one embodiment, for the above-mentioned auxiliary support component 5, the auxiliary support component 5 includes a support plate 501, a bottom support plate 502 is fixedly installed on the top of the support plate 501, the elastic clamping mechanism 6 includes a support spring 601, a clamping block 602 is fixedly installed on one end of the support spring 601, and a push rod 603 is fixedly installed on the outer surface of the clamping block 602.

[0040] The bottom support plate 502 is supported on the inner side of the second support column 301 by the support plate 501. When the second support column 301 gradually approaches the test bench 4, its bottom support plate 502 is in contact with the bottom surface of the test bench 4 and extends inward. At the same time, after the push rod 603 is relaxed, the support spring 601 drives the clamping block 602 to rebound and reset through its own elasticity, so that the end face of the clamping block 602 is in contact with the side of the pit box and is squeezed tightly.

[0041] The bottom support plate 502 is supported at a position below the test bench 4 by the support plate 501, so that when the pit box is undergoing a compression test, the second support column 301 and the bottom support plate 502 can cooperate to provide auxiliary support for the test bench 4, so that the compression support effect of the test bench 4 is better, and the clamping block 602 is respectively supported on the inner side of the first support column 201 and the second support column 301 by the support spring 601, thereby facilitating the provision of flexible clamping for the pit box test and preventing the placement position from shifting and affecting the test results.

[0042] In one embodiment, for the above-mentioned first support column 201, the first support column 201 and the second support column 301 are both provided with through holes, the inner wall of the second support column 301 is penetrated by and threadedly connected with a push screw 303, the top of the support platform 1 is provided with a slide groove 13, and the slider 302 is slidably connected to the inside of the slide groove 13.

[0043] The through holes are respectively located inside the first support column 201 and the second support column 301 to provide internal connection support space for the support spring 601. Since the push screw 303 passes through the second support column 301 and is connected to its internal thread, the second support column 301 can be slidably displaced inside the slide groove 13 along the top of the support platform 1 in cooperation with the slider 302 by rotating the push screw 303, so that the distance between the second support columns 301 and the second support columns 301 can be flexibly adjusted and the operation is convenient.

[0044] In one embodiment, for the above-mentioned driving device 7, the driving device 7 includes a driving cylinder 701, an output end of the driving cylinder 701 is provided with a telescopic push shaft 702, and the rotating sleeve 8 is rotatably connected to the outside of the telescopic push shaft 702.

[0045] By connecting the telescopic push shaft 702 with the rotating sleeve 8, when the driving cylinder 701 is started, it drives the telescopic push shaft 702 to retract and extend to generate thrust on the rotating sleeve 8, that is, pushes the chassis 9 and other components to move downward until they contact the top surface of the pit box to generate pressure on it, which can continuously provide pressure driving effect for the pit box testing process.

[0046] In one embodiment, for the above-mentioned pushing assembly 10, the pushing assembly 10 includes a rotating plate 101, a push plate 102 is rotatably installed at the bottom of the rotating plate 101, a slide bar 103 is fixedly installed at the bottom of the push plate 102, the pressure block 11 is fixed to the bottom of the slide bar 103, and a guide groove 14 is opened at the top of the chassis 9.

[0047] When the rotating sleeve 8 is rotated, it drives the rotating plate 101 to rotate to drive the push plate 102 and the slide bar 103 to slide inside the guide groove 14. When the slide bar 103 slides, it drives the pressure block 11 at the bottom to move together. When sliding inward, the position of the pressure block 11 shrinks inward, and when sliding outward, the pressure block 11 expands outward.

[0048] By arranging multiple sets of connecting plates 101 and pushing plates 102 on the outside of the rotating sleeve 8, they can be connected with multiple sets of sliding bars 103, and then pressure blocks 11 are arranged at different positions below the chassis 9, and their pressure test points can be changed at the same time, and then the range of pressure applied by the pressure block 11 can be flexibly changed according to the size of the pit box, and balanced pressure can be applied to the pit box for testing, so as to improve the accuracy of the pressure resistance test.

[0049] In one embodiment, for the pushing screw 303 , one end of the pushing screw 303 extends to the outside of the second support column 301 , and a twist knob 304 is fixedly mounted on one end of the pushing screw 303 .

[0050] By arranging a twist 304 at the end of the pushing screw 303, it is convenient to provide a driving support point for manipulating the pushing screw, so as to better drive the second supporting column 301 to move.

[0051] Through the above technical solution, 1. By arranging the first support assembly 2 and the second support assembly 3 on the top of the support platform 1, the first support assembly 2 and the second support assembly 3 can provide different support spacings according to pit boxes of different specifications under the cooperation, and the auxiliary support assembly 5 can cooperate at the bottom of the test platform 4 to provide auxiliary support. When the driving device 7 drives the pressure block 11 to descend and generate pressure on the pit box, the compressive support effect of the test platform 4 is better. While the driving device 7 drives the chassis 9 and the pressure block 11 to descend and generate pressure, the rotating sleeve 8 drives the pushing assembly 10 to push the pressure block 11 to move so that it can expand or contract and cooperate with the central pressure block 12 to generate pressure. 1. The bottom support plate 502 is supported at a position lower than the test bench 4 by the support plate 501, so that when the pit box is undergoing a pressure test, the second support column 301 and the bottom support plate 502 can cooperate to provide auxiliary support for the test bench 4, so that the pressure support effect of the test bench 4 is better, and the clamping block 602 is respectively supported on the inner side of the first support column 201 and the second support column 301 by the support spring 601, so as to provide a flexible clamping effect for the pit box test and prevent its placement position from shifting and affecting the test results.
