Description

Technical Field

[0001] The utility model relates to the technical field of packaging box detection, in particular to a food packaging box detection device. Background Technique

[0002] The material of food packaging boxes needs to be detected. It is necessary to not only detect the safety of the materials, but also detect the barrier performance of the materials. The detection of the barrier performance of packaging boxes is a key quality control step. The barrier performance mainly refers to the ability of packaging materials to block gases and water vapor, which is an important factor to ensure the shelf life and quality of food.

[0003] At present, when the existing barrier performance testing device is testing, the operator needs to place the cut sample on the test position and smooth it out, and then cover the test top cover for testing. This solution provides a food packaging box detection device, which is specifically provided with a flattening mechanism for the packaging box material, so that the sample can always maintain a flat and pressed and positioned state during the process of being pressed and covered by the top cover. Content of the Utility Model

[0004] The utility model aims to at least solve the problem in the prior art that there is a lack of a sample smoothing mechanism and the smoothing of the sample requires manual assistance.

[0005] This solution provides a food packaging box detection device, which is achieved by the following specific technical means: including a test machine base and a vertical frame fixed on the top of the test base. At the same time, a test box is fixed on the vertical frame, and there is a top cover covering the top opening of the test box above the test box. The vertical frame is rotatably provided with a first shaft and a second shaft. Both the first shaft and the second shaft are fixed with swing arms. At the same time, C-shaped grooves are symmetrically opened on both sides of the vertical frame close to the test box. A first sliding seat slides on each group of swing arms. At the same time, a second sliding seat slides in the C-shaped groove. The horizontal shaft fixedly installed on the first sliding seat extends through the second sliding seat to the outside of the test box. At the same time, a pressure roller is sleeved on the horizontal shaft. There is a gap between the pressure roller and the top wall of the test box when the horizontal shaft is located at the horizontal section at the top of the C-shaped groove. When the horizontal shaft is located in the vertical section of the C-shaped groove, the pressure roller elastically presses and contacts the side wall of the test box, presses on both ends of the sample and strokes the sample into a flattened state, and then the top cover can be closed.

[0006] Preferred Technical Solution 1: A support frame is fixed on the outer wall of the top cover. A linkage mechanism is connected between the support frame and the first shaft and the second shaft. The linkage mechanism can drive the top cover to gradually move down to complete the covering of the top cover while driving the pressure roller to move down to flatten the sample when the first shaft and the second shaft rotate.

[0007] Preferred Technical Solution 2: The linkage mechanism includes gears fixedly sleeved on the first shaft and the second shaft, and two sets of racks fixed on the support frame and slidably connected to the vertical frame. The two sides of the two sets of racks are respectively engaged with the two sets of gears, achieving the technical effect of simultaneously driving the pressure roller and the top cover to move downward when the swing arm swings downward.

[0008] Preferred Technical Solution 3: An oxygen concentration sensor and a humidity sensor are arranged inside the top cover. The test chamber is communicated with an oxygen supply device and a water vapor generating device inside the test machine base through two sets of pipelines respectively.

[0009] Preferred Technical Solution 4: A controller is installed on the test machine base, and the controller is electrically connected to the oxygen supply device, the water vapor generating device, the oxygen concentration sensor, and the humidity sensor.

[0010] Preferred Technical Solution 5: An exhaust pipe is provided on the top cover.

[0011] Adopting the above structure enables this solution to have the following beneficial effects:

[0012] 1. The pressure roller connected by the swing arm can flatten and press the placed specimen, so that the specimen is always in a flat state during the closing process of the top cover, and for some soft packaging materials, manual flattening is not required;

[0013] 2. By setting the linkage mechanism, the linkage control of the flattening action of the specimen and the downward pressing action of the top cover is realized, improving the convenience of operation. Description of the Drawings

[0022] Please refer to Figures 1-5 , a food packaging box testing device, including a test base 1 and an upright frame 2 fixed on the top of the test base. At the same time, a test box 3 is fixed on the upright frame 2, and there is a top cover 4 above the test box 3 that can cover the top opening of the test box 3. The upright frame 2 is rotatably provided with a shaft 1 5 and a shaft 2 6, and swing arms 7 are fixed on both the shaft 1 5 and the shaft 2 6. At the same time, C-shaped grooves 21 are symmetrically opened on both sides of the upright frame 2 close to the outside of the test box 3. The horizontal section at the top of the C-shaped groove 21 is located above the test box 3, and the vertical section of the C-shaped groove 21 is close to the side wall of the test box 3. A slide block 1 8 slides on each group of swing arms 7, and at the same time, a slide block 2 9 slides in the C-shaped groove 21. A cross shaft 10 fixedly installed on a group of slide blocks 1 8 extends to the outside of the test box 3 after passing through a corresponding group of slide blocks 2 9. At the same time, a pressing roller 101 is sleeved on the cross shaft 10. When the pressing roller 101 is located at the horizontal section at the top of the C-shaped groove 21, there is enough clearance between the bottom side of the pressing roller 101 and the top wall of the test box 3 for the specimen to pass through. At the same time, when the cross shaft 10 is located in the vertical section of the C-shaped groove 21, the pressing roller 101 is in elastic pressing contact with the side wall of the test box 3. The roller surface of the pressing roller 101 is coated with an elastic layer, so that when the two groups of pressing rollers 101 move down along the vertical section when the swing arms 7 swing downward, they can press on both ends of the specimen and smooth the specimen into a flat state. Then, the top cover 4 can be closed for testing. An oxygen concentration sensor 12 and a humidity sensor 13 are arranged in the top cover 4. The test box 3 is connected to an oxygen supply device and a water vapor generating device in the test base 1 through two groups of pipelines respectively. The oxygen concentration sensor 12 is used to detect the change in the oxygen concentration in the top cover 4 after the top cover 4 is closed and the oxygen supply device is started, so as to detect the gas barrier performance of the food packaging box material; the humidity sensor 13 is used to detect the change in the humidity in the top cover 4 after the top cover 4 is closed and the water vapor generating device is started, so as to detect the water vapor barrier performance of the food packaging box material.

The two groups of racks 112 are respectively meshed with the two groups of gears 111. At the same time, the two groups of racks 112 are located outside the two groups of gears 111, achieving the technical effect of driving the pressing roller 101 and the top cover 4 to move downward simultaneously when the swing arm 7 swings downward, and driving the pressing roller 101 and the top cover 4 to move upward away from the specimen when the swing arm 7 swings upward, and can also realize the synchronous and opposite-direction linkage of the two groups of swing arms 7. At the same time, the vertical frame 2 is arranged on the front and rear sides of the test box 3, and the linkage mechanism 11 is also symmetrically distributed on the front and rear sides of the test box 3. And a sealing ring is arranged at the bottom port of the top cover 4 to seal when the top cover 4 is closed with the top port of the test box 3;
