Description

Technical Field

[0001] The utility model relates to the technical field of food safety detection, in particular to an air tightness detection frame for food safety packaging bags. Background Art

[0002] At present, when people test the packaging of puffed food, they often need to manually test the food bags for air leaks. However, during the testing process, it is generally impossible to detect the slow air leaks from the food bags. The existing methods for detecting air leaks in packaging are mostly to put the packaging bags in water to observe whether there are air leaks. During the testing process, water will inevitably be spilled on the ground, breeding bacteria, causing damage to the production environment and sanitation, which will harm the production quality. At the same time, mechanical testing is prone to being unable to control the force, resulting in damage to the packaging bags. Utility Model Content

[0003] The utility model aims to provide an air tightness detection frame for food safety packaging bags, so as to overcome the above-mentioned defects in the prior art.

[0005] The beneficial effects of the utility model are:

[0006] Through the two sets of second baffles distributed on the left and right, the center of the food packaging bag entering the detection box is automatically positioned under the force of the torsion spring, which is convenient for subsequent detection work. After changing the distance between the fixed rod and the sliding rod, the card pin is inserted, and the user controls the sliding rod to slide up and down on the fixed rod to make the card pin engage with the side wall of the card slot. The position is changed according to the size of the food packaging bag, which can be suitable for sealing detection of packaging bags of different sizes. The lower ends of the two sliding rods are tilted outward to prevent the sliding rods from squeezing the packaging bag downward and causing damage to the packaging bag. The size of the packaging bag is adjusted, and there is no need to control the detection force. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Reference Figure 1-Figure 7 According to an embodiment of the utility model, a food safety packaging bag air tightness detection frame includes a fixed plate 10, and the upper and lower ends of the fixed plate 10 are respectively fixed with a detection box 11 and a collection box 12, and the front end of the detection box 11 is connected and fixed with a feeding box 25, and the detection box 11 and the collection box 12 are both opened and connected up and down, and a power motor 13 is fixed on the lower end surface of the fixed plate 10, and the upper end of the power motor 13 is connected to a bidirectional screw 14, and the outer periphery of the bidirectional screw 14 is threadedly connected with a mounting frame 15, and a detachable fixed pressure block 16 is fixed on the mounting frame 15, and two left-right symmetrical guide slide rods 17 are fixed on the upper end surface of the fixed plate 10, and the left and right ends of the mounting frame 15 are slidably matched with the two guide slide rods 17, and the lower end of the fixed pressure block 16 is provided with an upwardly arranged groove 18, and the groove 18 is connected and opened with evenly distributed vents 19, and the fixed pressure block 1 6 is embedded with an air leakage detector 20, the lower end of which is connected with the evenly distributed vent holes 19, a through cavity is provided on the fixed plate 10, the left and right side walls of the through cavity are hinged with first baffles 28, the two first baffles 28 are connected with the left and right inner end surfaces of the collecting box 12 with reset springs 27, the detection box 11 is connected with two groups of left-right symmetrical second baffles 26, the second baffles 26 are connected with the detection box 11 through a hinge rod, the hinge rod is connected with a torsion spring, the lower end of the fixed pressure block 16 is fixed with two left-right symmetrical fixed rods 21, the two fixed rods 21 are slidably connected with sliding rods 24, the fixed rods 21 are provided with card slots 22 evenly distributed up and down, the sliding rods 24 are inserted with card pins 23, the card pins 23 can be carded with the card slots 22, the lower ends of the sliding rods 24 are inclined, and the inclination directions of the lower ends of the two sliding rods 24 are opposite;

[0020] The food packaging bag containing food enters the detection box 11 through the connection between the feeding box 25 and the detection box 11, and abuts against the two first baffles 28 at the lower end. The food packaging bag abuts against the second baffles 26 through two groups of left-right symmetrically arranged second baffles 26 provided on the detection box 11, and the center of the food packaging bag is positioned under the action of the torsion spring force;

[0021] The power motor 13 is powered on and can drive the bidirectional screw 14 to rotate. The rotation of the bidirectional screw 14 drives the threaded mounting frame 15 to slide up and down, so that the lower end of the fixed pressing block 16 abuts against the food packaging bag, and the groove 18 at the fixed pressing block 16 abuts against the left and right ends of the food packaging bag, and force is applied downward to the food packaging bag. As the fixed pressing block 16 moves downward, the fixed pressing block 16 and the two first baffles 28 at the lower end squeeze the food packaging bag, and the air leakage detector 20 is used to detect whether there is air leakage in the food packaging bag. If there is air leakage, the gas enters the vent 19 and can be detected by the air leakage detector 20. Otherwise, the air leakage detector 20 fails to detect it. The leakage phenomenon is detected, indicating that the food packaging bag is well sealed. The sliding rod 24 on the fixed rod 21 abuts against the first baffle 28 by the lowering of the fixed pressure block 16. The fixed rod 21 abuts against the first baffle 28 to apply downward force, so that the first baffle 28 overcomes the spring force of the return spring 27 and rotates downward with the hinge rod as the rotation axis. By pulling the card pin 23, the card pin 23 and the fixed rod 21 are separated from the card connection setting. The user controls the sliding rod 24 to slide up and down on the fixed rod 21, and after changing the distance between the fixed rod 21 and the sliding rod 24, the card pin 23 is inserted, so that the card pin 23 is carded on the side wall of the card slot 22, and the position is changed according to the size of the food packaging bag.

[0022] After passing through the two first baffles 28, the food packaging bag enters the collection box 12 and slides downward to be collected.

[0023] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
