Description
Technical Field
[0001] The utility model relates to the technical field of a carton opening force tester, in particular to a carton opening force tester fixture and a carton opening force tester. Background Art
[0002] The carton opening force tester, also known as the carton opening and closing force tester or carton opening force tester, is suitable for testing the opening pressure of the carton. The size of the opening force can affect the production efficiency of the carton. When the opening force is within an appropriate range, the carton will open smoothly and conveniently.
[0003] Carton opening force tester, such as Figure 1 and Figure 2 As shown, it includes a frame 50, on which a workbench 51 and a lifting mechanism 52 are provided, the lifting mechanism 52 is arranged above the workbench 51, a first clamp 10 is provided at the lower end of the lifting mechanism 52, the first clamp 10 is provided with a sensing probe (not shown in the figure), a second clamp 20 is provided on the workbench 51, the first clamp 10 is arranged above the second clamp 20, a first card slot 11 is provided on the lower surface of the first clamp 10, and a second card slot 21 is provided on the upper surface of the second clamp 20.
[0004] The measuring principle of the carton opening force tester is to place the carton 30 in the second slot 21, and the lifting mechanism 52 drives the first clamp 10 to move downward, and the first slot 11 and the second slot 21 squeeze the carton diagonally. When the carton 30 is opened diagonally, the induction probe on the first clamp 10 collects the force value changes during the test, and the maximum force value will be memorized and the test results will be displayed.
[0005] When the specification of the paper box 30 to be tested is large (when the first clamp 10 and the second clamp 20 are in contact, the diagonal length of the unopened paper box 30 is greater than the distance between the bottoms of the first card slot 11 and the second card slot 21), the first clamp 10 and the second clamp 20 can smoothly open the paper box 30 along the diagonal.
[0006] like Figure 2 As shown, when the specifications of the paper box 30 to be tested are small (when the first clamp 10 and the second clamp 20 are in contact, the diagonal length of the unopened paper box 30 is equal to or less than the distance between the bottoms of the first card slot 11 and the second card slot 21), the first clamp 10 drops to the lowest position (when it is in contact with the second clamp 20), and it is unable to press down or even contact the paper box 30, and the opening force test of the small-sized paper box 30 cannot be implemented.
[0007] In this regard, currently, the first fixture or the second fixture is usually re-customized, and when testing the opening force of a small-sized paper box, the first fixture or the second fixture is disassembled and replaced before testing. Since the first fixture and the second fixture are usually fixed to the lifting mechanism and the workbench respectively using fasteners such as bolts, the disassembly and replacement operation will increase the time cost; and the disassembly and replacement operation is easy to bump against the sensor probe, increasing the risk of damage to the sensor probe.

It is worth noting that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element 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 present invention.
[0035] Embodiment 1:
[0036] A paper box opening force tester fixture, such as Figure 1 and Figure 2 As shown, it includes a first fixture 10 and a second fixture 20. The lower surface of the first fixture 10 is provided with a first slot 11, and the upper surface of the second fixture 20 is provided with a second slot 21. The first slot 11 and the second slot 21 are both V-shaped. An induction probe (not shown in the figure) is installed on the first fixture 10.
[0037] like Figure 1 and Figure 2 As shown, the first card slot 11 and the second card slot 21 are both connected in the front-to-back direction. Because the first card slot 11 and the second card slot 21 are both connected in the front-to-back direction, the length of the paper box 30 to be tested is not limited, and the paper boxes 30 to be tested of different lengths can be adapted, which is conducive to improving the flexibility of use during testing.
[0038] like Figure 3 , Figure 4 , Figure 5 As shown, the slot width of the first slot 11 is D1, the slot width of the second slot 21 is D2, the slot depth of the first slot 11 is H1, and the slot depth of the second slot 21 is H2. When the first clamp 10 and the second clamp 20 are in contact, the distance between the bottoms of the first slot 11 and the second slot 21 is A1.
[0039] like Figure 3 As shown, when D1 = D2, if the first clamp 10 and the second clamp 20 are in contact with each other, then A1 = H1 + H2.
[0040] like Figure 4 and Figure 5 As shown, when D1>D2, or when D1<D2, if the first clamp 10 and the second clamp 20 are in contact with each other, then A1
[0041] like Figure 6 As shown, a third clamp 40 is placed in the second clamping groove 21. A third clamping groove 41 is provided on the upper surface of the third clamp 40, and the third clamping groove 41 also adopts a V-shaped groove.
[0042] like Figure 6 and Figure 8 As shown, the third card slot 41 is through in the front-to-back direction. The third card slot 41 is through in the front-to-back direction and can also adapt to the paper boxes 30 to be tested of different lengths.
[0043] like Figure 6 As shown, the width of the third slot 41 is D3, and the depth of the third slot 41 is H3. When the first fixture 10 and the third fixture 40 are in contact, the distance between the bottoms of the first slot 11 and the third slot 41 is A2.
[0044] like Figure 8 As shown, a first clamping plate 42 is fixedly installed (for example, welded) on the front side of the third clamp 40, and a second clamping plate 43 is fixedly installed on the rear side of the third clamp 40. Fig.10 As shown, after the third clamp 40 is placed in the second clamping slot 21 , the second clamp 20 is disposed between the first clamping plate 42 and the second clamping plate 43 .
[0045] like Fig.10 As shown, the arrangement of the first clamp plate 42 and the second clamp plate 43 can prevent the third fixture 40 from slipping from the front or back of the second slot 21, thereby improving the reliability of the third fixture 40 placed in the second slot 21, which is beneficial to improving the reliability during testing.
[0046] like Fig.10 As shown, when in use, the first clamp 10 needs to be installed at the lower end of the lifting mechanism 52 in the carton opening force tester, and the second clamp 20 needs to be installed on the workbench 51, and the lifting mechanism 52 and the workbench 51 are both installed on the frame 50.
[0047] like Figure 7 As shown, the diagonal length of the large-sized paper box 30 before opening is recorded as L1, and the diagonal length of the small-sized paper box 30 before opening is recorded as L2. L1>A1≥L2>A2.
[0048] If the first clamp 10 and the second clamp 20 are used to open the large-sized paper box 30, because L1>A1, the first clamp 10 can smoothly contact the large-sized paper box 30 before the first clamp 10 descends and abuts the second clamp 20. Therefore, as the first clamp 10 continues to move downward, the large-sized paper box 30 can be smoothly opened along the diagonal under the squeezing of the first card slot 11 and the second card slot 21.
[0049] If the first clamp 10 and the second clamp 20 are used to open a small-sized paper box 30, because L2≤A1, when the first clamp 10 descends and abuts against the second clamp 20, the first clamp 10 cannot press down or even contact the paper box 30, so the small-sized paper box 30 cannot be opened. At this time, the third clamp 40 needs to be placed in the second card slot 21 of the second clamp 20, such as Fig.11 As shown, because L2>A2, the first clamp 10 can smoothly contact the small-sized paper box 30 before the first clamp 10 descends and abuts against the third clamp 40. As the first clamp 10 moves downward, the small-sized paper box 30 can be smoothly opened along the diagonal under the squeezing of the first slot 11 and the third slot 41.
[0050] From the above introduction, it can be known that the small-sized paper box 30 means that the diagonal length L2 of the small-sized paper box 30 before opening is less than or equal to the bottom spacing A1 of the first card slot 11 and the second card slot 21 when the first clamp 10 and the second clamp 20 are abutted, and the diagonal length L2 of the small-sized paper box 30 before opening is greater than the bottom spacing A2 of the first card slot 11 and the third card slot 41 when the first clamp 10 and the third clamp 40 are abutted.
[0051] Therefore, when testing the opening force of a small-sized paper box 30, the third clamp 40 is placed in the second slot 21 of the second clamp 20, so that when the first clamp 10 moves down, the first clamp 10 and the third clamp 40 can smoothly squeeze and open the small-sized paper box 30. The operation of placing the third clamp 40 is simple and convenient, and there is no need to disassemble and replace the first clamp 10 or the second clamp 20, which is conducive to saving time and reducing the risk of damaging the sensor probe.
[0052] Embodiment 2:

[0055] The lower end of the first upper inclined plate 44 and the lower end of the second upper inclined plate 45 are welded and fixed, the upper end of the first upper inclined plate 44 is inclined to the left, and the upper end of the second upper inclined plate 45 is inclined to the right, a third slot 41 is provided between the first upper inclined plate 44 and the second upper inclined plate 45, the upper end of the first upper inclined plate 44 is welded and fixed to the upper end of the first lower inclined plate 48 via the first connecting plate 46, the upper end of the second upper inclined plate 45 is welded and fixed to the upper end of the second lower inclined plate 49 via the second connecting plate 47, and the lower end of the first lower inclined plate 48 and the lower end of the second lower inclined plate 49 are welded and fixed.
[0056] When the third clamp 40 is placed in the second slot 21 , the lower surface of the first lower inclined plate 48 and the lower surface of the second lower inclined plate 49 are both in contact with the slot wall of the second slot 21 .
[0057] The third clamp 40 provided in the second embodiment has a simple structure and is easy to process and assemble, thereby improving processing efficiency.
[0058] Furthermore, because the first lower inclined plate 48 and the second lower inclined plate 49 can be attached to the groove wall of the second slot 21, the stability and reliability of the third fixture 40 placed in the second slot 21 can be improved, which is beneficial to improving the reliability during testing.
[0059] Embodiment 3:
