Description

Technical Field

[0001] The utility model relates to the field of product outer packaging, in particular to a corrugated paperboard oil-proof property testing device. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body. It has high mechanical strength and can withstand collisions and falls during transportation. Therefore, it is often used to package goods for long-distance transportation. In terms of food transportation, frozen fresh foods sold wholesale are usually packaged and transported in cartons made of corrugated cardboard.

[0003] Some foods (such as meat) have a high fat content. During long-distance transportation, the fat in the food will precipitate and penetrate into the corrugated paper. After a long period of leakage, the corrugated paperboard will become soft, thus affecting the strength of the corrugated paperboard box. When transportation workers are carrying goods, the corrugated paperboard box is prone to breakage and the food in the corrugated paperboard box leaks, causing economic losses.

[0004] Therefore, we need to test the oil penetration limit of corrugated cardboard before leaving the factory. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the attached embodiment of the present utility model Figure 1-9 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0027] Embodiment 1:

[0028] like Figures 1 to 6As shown, the utility model discloses a corrugated cardboard oil-proof property testing device, including a test bench 1, a mounting frame 2 is fixedly connected to the test bench 1, a transparent burette 3 is fixedly connected to the mounting frame 2, and a scale (not shown) is arranged on the side wall of the transparent burette 3, and a first solenoid valve 31 is fixedly connected to the lower end of the transparent burette 3. Further, the test bench 1 is fixedly connected to a placement seat 4 just below the transparent burette 3, a test funnel 5 is fixedly connected to the upper end of the placement seat 4, a placement table 51 is fixedly connected to the inner side wall of the test funnel 5, and a detection mechanism is arranged at the lower end of the placement seat 4.

[0029] The specific connection method between the mounting frame 2 and the burette is as follows: a clamping plate 21 is fixedly connected to the mounting frame 2, a through hole 22 is provided on the clamping plate 21, and the transparent burette 3 passes through the through hole 22; a stabilizing frame 23 is symmetrically provided at the lower end of the clamping plate 21, and the stabilizing frame 23 is supported on the lower end of the transparent burette 3. Through the above structure, the burette is prevented from falling off the mounting frame 2, and an observation slot 24 connected to the through hole 22 is provided on the clamping plate 21. When installing the burette, the scale on the burette should be turned toward the observation slot 24, so that the tester can observe the amount of oil added when dropping the oil liquid.

[0030] Furthermore, a V-shaped ring groove 52 is provided on the upper end surface of the placement table 51, a conical insert ring 61 is fixedly connected to the lower end surface of the fixed pressure ring 6, the conical insert ring 61 is inserted into the V-shaped ring groove 52, and a sealing ring 62 is fixedly connected to the inner wall of the fixed pressure ring 6. After the tester places the test sample on the placement table 51, the conical insert ring 61 on the fixed pressure ring 6 is inserted into the V-shaped ring groove 52, so that the fixed pressure ring 6 is pressed against the upper end of the test sample. Through the above structure, while fixing the test sample, it is possible to prevent the oil on the corrugated cardboard from flowing into the test funnel 5 through the gap between the corrugated cardboard and the placement table 51, thereby affecting the accuracy of the test results.

[0031] Furthermore, the detection mechanism includes a water reservoir 71, a filter box 72, a water pipe 73 and a water pump 74. The water reservoir 71 is fixedly connected to the lower end of the placement seat 4, and colorless and transparent pure water is stored in the water reservoir 71. The lower end of the test funnel 5 is fixedly connected to a water pipe 75 connected to the water inlet of the filter box 72, and a second solenoid valve 76 is fixedly connected to the water pipe 75. The water pipe 73 is fixedly connected between the water outlet of the filter box 72 and the water reservoir 71, and the water pump 74 is fixedly connected to the water pipe 73.

[0032] After adding a certain amount of dyed oil to the test sample, the tester starts timing and observes the water reservoir 71 below. When the oil completely penetrates through the test sample and drips into the water reservoir 71, since pure water is colorless and transparent, the dyed oil is more obvious when it drips into the water reservoir 71. When the tester finds that the color of the pure water in the water reservoir 71 has changed, he immediately starts the meter and records it, and the limit value of the test sample's oil penetration resistance can be recorded.

[0033] In order to facilitate observation by testers, the rear side wall and the left and right side walls of the water reservoir 71 are made of white opaque material, and the front side wall of the water reservoir 71 is colorless transparent glass, thereby highlighting the dyed oil and facilitating testers to observe and record data in time when the oil drips into the pure water.

[0034] Embodiment 2:

[0035] like Figure 8-9 As shown, the structure of Example 2 is substantially the same as that of Example 1, and the difference from Example 1 is that the detection mechanism in this embodiment includes a control panel 81, a small laser transmitter 82, and a small laser receiver 83. The control panel 81 is fixedly connected to the test bench 1, and the small laser transmitter 82 and the small laser receiver 83 are symmetrically arranged on both sides of the placement seat 4, and the height of the small laser transmitter 82 and the small laser receiver 83 are both lower than the height of the placement seat 4.

[0036] In this embodiment, the working principle of the detection mechanism is as follows: when the test starts, the control panel 81 starts timing, the laser beam emitted by the small laser transmitter 82 passes through the falling path of the oil drop, and when the oil drop falls and passes through the laser beam, the small laser receiver 83 transmits the signal to the control panel 81, and the control panel 81 stops timing and saves the data after receiving the signal. The tester records the data measured by the control panel 81 to know the oil penetration limit value of the test sample. And the test bench 1 is fixedly connected with a fixing seat 84 directly below the placement seat 4, and a number of oil-absorbing papers (not shown in the figure) for absorbing oil are placed in the fixing seat 84.

[0037] Furthermore, since the inner diameter of the test funnel 5 is relatively large and less oil penetrates, in order to allow the penetrated oil to accurately pass through the laser beam, a tightening tube 54 is fixedly connected to the lower end of the test funnel 5. The inner diameter of the tightening tube 54 is much smaller than the inner diameter of the test funnel 5. The oil flows into the tightening tube 54 and then flows out to accurately pass through the laser beam.

[0038] It should be noted here that in this embodiment, there are a lot of mature technologies to support the functions to be realized by the control panel 81, the small laser transmitter 82 and the small laser receiver 83. The essence of the utility model is to optimize the combination of existing hardware machine connection methods for specific application scenarios to adapt to the time required to measure the complete penetration of the oil into the test sample (without changing the internal structure of the control panel 81, the small laser transmitter 82 and the small laser receiver 83).

[0039] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.
