Description

Technical Field

[0001] The invention relates to the technical field of pressure testing, in particular to an industrial plastic barrel pressure resistance testing device. Background Art

[0002] As packaging materials, industrial plastic barrels are widely used in the fields of chemical, medical, food, electromechanical, etc., and the compression resistance test is crucial to ensure product quality and safety. Through compression testing, the maximum load-bearing capacity of plastic barrels can be determined, thereby ensuring that they can maintain good structural integrity and functionality under various conditions of use. In addition, the test results can also provide important references for packaging design, guide packaging design optimization, and further improve the compression resistance and safety of products.

[0003] In the prior art, the compression test device for industrial plastic barrels directly uses hydraulic equipment to apply pressure downward to the industrial plastic barrel to be tested, and controls the pressure to gradually increase until the industrial plastic barrel is deformed, so as to obtain the maximum pressure data that the industrial plastic barrel can withstand. However, during actual stacking, the area range of the top of each industrial plastic barrel that is pressed cannot be guaranteed to be completely consistent. When a small-sized industrial plastic barrel or other object is stacked on top of a large-sized industrial plastic barrel, the pressure range applied to the industrial plastic barrel cannot cover the entire area of ​​the end face, and conventional testing devices cannot regulate such scenarios where the pressure range and area are not fixed. This results in an incomplete test. On the other hand, some industrial plastic barrels are stacked after being laid down horizontally. After stacking, the pressure area of ​​the top layer on the bottom barrel body does not act on the highest point, but on the side area between the middle and the highest point. Conventional testing devices cannot simulate the pressure data that multiple industrial plastic barrels can withstand after being laid down horizontally and stacked. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] See also Figures 1 to 6 The present invention provides the following technical solutions: an industrial plastic barrel compression test device, comprising a test device body, the test device body comprising a test frame 1, a clamping assembly 3, a transmission mechanism 4 and a boosting mechanism 2, side baffles 9 are welded on both sides of the test frame 1, the clamping assembly 3 comprises a first clamping plate 13 and a second clamping plate 21, and the bottoms of the first clamping plate 13 and the second clamping plate 21 are both integrally formed with a slider 22, a groove 23 is provided on the surface of the second clamping plate 21, a transmission mechanism 4 is embedded in the groove 23, a deformation detection assembly 5 is installed at one end of the transmission mechanism 4, and the top of the deformation detection assembly 5 passes upward from the top of the second clamping plate 21, a top plate 8 is welded on the top of the test frame 1, the boosting mechanism 2 is screwed under the top plate 8, the boosting mechanism 2 applies vertical downward pressure to the end or side of the industrial plastic barrel to be tested through the bottom, and a hydraulic rod 14 is welded on the top of the boosting mechanism 2. The industrial plastic barrel compression test device is used for the industrial plastic barrel to be tested in a vertically placed state, such as Figure 1 As shown, pressure is applied from the top to obtain the compressive resistance data of the end of the industrial plastic barrel to be tested; it is also possible to place two plastic barrels to be tested side by side horizontally, as shown Figure 2As shown, downward pressure is applied from the middle of two plastic barrels to obtain the compressive strength data of the plastic barrels when they are staggered and stacked, and a single plastic barrel to be tested is placed horizontally, and pressure is applied directly from the top of the plastic barrel to be tested to obtain the compressive strength data of the plastic barrel to be tested after direct stacking (each layer of plastic barrels to be tested is not staggered and stacked).

[0028] When the present invention is used, the compression resistance data under the above three different placement forms are tested respectively. When each form is tested, the downward pressure is provided by the hydraulic rod 14 at the top, and when the pressure is applied to the top of the vertically placed plastic barrel to be tested, the booster mechanism 2 indirectly acts the pressure on the top of the vertically placed plastic barrel to be tested through the transmission mechanism 4, and obtains the maximum compression resistance data of the plastic barrel to be tested under different pressing areas by changing the contact position and range between the transmission mechanism 4 and the top of the plastic barrel to be tested. When the compression resistance test is performed on the side of the horizontally placed plastic barrel to be tested, the pressure is not transmitted through the transmission mechanism 4, but directly pressed on the side of the plastic barrel to be tested through the booster mechanism 2 to directly obtain the compression resistance data. Whether the compression test is performed on the end or the side of the plastic barrel to be tested, the deformation detection component 5 carried on the transmission mechanism 4 is used to realize that after the plastic barrel to be tested is deformed by high pressure, the two electrode sheets in the deformation detection component 5 are automatically separated, thereby generating a change in the electrical signal, and timely judging that the plastic barrel to be tested has begun to deform.

[0029] In this embodiment, the test frame 1 includes a bottom plate 6 and a support frame 7, the support frame 7 is welded to the rear end of the bottom plate 6, the side baffles 9 are welded to the two sides of the bottom plate 6, a telescopic sleeve 10 is welded to the top of each side baffle 9, and a slide groove 12 is provided on the surface of the bottom plate 6. There are two slide grooves 12, and both ends of each slide groove 12 extend to the bottom of the side baffle 9, there are four telescopic sleeves 10, and the telescopic sleeves 10 on each side baffle 9 are aligned with each other.

[0030] Specifically, each side baffle 9 controls the first clamping plate 13 and the second clamping plate 21 to slide along the bottom slide groove 12 respectively through the electric telescopic rod 11, and through this structure, when testing the vertically placed plastic barrel to be tested, the second clamping plate 21 can be used to change the position of the transmission mechanism 4, and when testing the horizontally placed plastic barrel to be tested, a blocking effect can be provided to the plastic barrel to be tested from the side to prevent the plastic barrel from rolling, thereby improving the stability of the detection process.

[0031] In this embodiment, the bottoms of the first clamping plate 13 and the second clamping plate 21 are embedded in the inside of the slide groove 12 through the slider 22, and the inside of the groove 23 is welded with a guide rod 24. The transmission mechanism 4 includes a lifting plate 25 and an adjustment plate 26, and the surface of the lifting plate 25 is provided with a guide hole 32. The adjustment plate 26 is a circular structure as a whole, and the guide rod 24 passes through the inside of the guide hole 32. The sides of the first clamping plate 13 and the second clamping plate 21 are both screwed with electric telescopic rods 11, and the ends of each electric telescopic rod 11 are screwed into the inside of the telescopic sleeve 10. The pressure applied by the boosting mechanism 2 is indirectly applied to the top of the industrial plastic barrel to be tested through the transmission mechanism 4, so that the scene with unfixed pressure range and area can be simulated, and multiple test tasks with different pressure ranges and areas can be quickly switched, which improves the test efficiency. The pressure provided by the boosting mechanism 2 can also be stably applied after adjusting the pressing range, which improves the test stability.

[0032] Specifically, when the second clamping plate 21 part is translated through the electric telescopic rod 11 at the rear end, it will also drive the entire transmission mechanism 4 to translate, thereby changing the range of the top area of ​​the plastic barrel to be tested that is pressed by the adjustment plate 26 in a vertical state, and the booster mechanism 2 directly applies pressure to the top of the plastic barrel to be tested through the adjustment plate 26. Therefore, after controlling the electric telescopic rod 11 to change the area where the adjustment plate 26 presses on the plastic barrel to be tested, the area where the pressure acts on the top of the plastic barrel to be tested can be changed, thereby simulating the maximum pressure that the plastic barrel to be tested can withstand when a small plastic barrel or other object is placed on the top.

[0033] In this embodiment, the deformation detection assembly 5 includes a lifting channel 27 and a locking column 28. The locking column 28 passes through the inside of the lifting channel 27. A locking bolt 29 is inserted into one side of the lifting channel 27. The end of the locking bolt 29 is against the surface of the locking column 28. The bottom of the locking column 28 is embedded with a first electrode sheet 30. The surface of the lifting plate 25 is embedded with a second electrode sheet 31. The first electrode sheet 30 and the second electrode sheet 31 are aligned. The top of the locking column 28 is plugged with a signal line 33. The side of the lifting plate 25 fits with the inner wall of the groove 23, and the surface of the locking column 28 fits with the inner wall of the lifting channel 27. Through the deformation detection assembly 5 on the side, once the industrial plastic barrel is deformed during the test, it can be quickly detected, and the detection scheme can be accurately triggered in any type of pressure test operation, so that the final test result is more reliable and effective.

[0034] Specifically, when testing a plastic barrel to be tested in a vertical state, first lift the boosting mechanism 2, place the adjustment plate 26 on the transmission mechanism 4 on the top of the plastic barrel to be tested, and control the locking plate to move downward until the first electrode sheet 30 and the second electrode sheet 31 are in contact with each other. At this time, the locking column 28 can be locked against it by the locking bolt 29. During the subsequent boosting process, once the pressure provided by the boosting mechanism acts on the top of the plastic barrel to be tested and causes deformation, the adjustment plate 26 will move downward, while the locking column 28 will not move downward due to the compression of the locking bolt 29, thereby causing the first electrode sheet 30 and the second electrode sheet 31 to separate, thereby achieving the phenomenon of disconnecting the electrical signal. When testing a horizontally placed plastic barrel to be tested, the adjustment plate 26 needs to be at the top of the boosting mechanism 2. When the plastic barrel to be tested is deformed, the adjustment plate 26 moves downward synchronously on the top of the dispersion pressure plate 15 to separate the electrode sheets.

[0035] In this embodiment, the boost mechanism 2 includes an arc plate 17 and a central pressure plate 19. A telescopic rod 18 is welded to one side of the bottom end of the arc plate 17. The end of the telescopic rod 18 is embedded in the center pressure plate 19. A connecting plate 20 is integrally formed on the top of the center pressure plate 19. A dispersion pressure plate 15 is integrally formed on the top of the connecting plate 20. An extension convex plate 16 is welded to the surface of the dispersion pressure plate 15. The bottom of the hydraulic rod 14 is screwed to the surface of the extension convex plate 16, and the distance between the two hydraulic rods 14 is greater than the diameter of the adjustment plate 26. The bottom surface of the dispersion pressure plate 15 is in contact with the top of the arc plate 17, and the bottom of each arc plate 17 is flush with the bottom surface of the center pressure plate 19. The side of the industrial plastic barrel can be pressurized and tested, and the pressure data that multiple industrial plastic barrels can withstand after being stacked horizontally can be simulated. The pressurization range can also be flexibly adjusted at the oblique side and top of the industrial plastic barrel, so that the test is more comprehensive and the test range is wider.

[0036] Specifically, when testing a vertically placed plastic barrel, the pressure provided by the hydraulic rod 14 at the top will be applied to the adjustment plate 26 through the central pressure plate 19 at the bottom and the arc plates 17 on both sides, and then directly applied to the area in contact with the top of the plastic barrel with the help of the adjustment plate 26. If testing is performed on a horizontally placed plastic barrel, when two parallel plastic barrels are tested, pressure is applied from the middle arc edge, such as Figure 2 In the state shown, pressure can be directly applied to the side of the plastic barrel to be tested through the arc plates 17 on both sides. If pressure is only provided to the top of a single side of the plastic barrel to be tested, pressure will only be applied to the top area of ​​the horizontally placed plastic barrel to be tested through the central pressure plate 19.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
