[0022] The following will be combined with the drawings in the embodiments of the utility model to 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 the embodiments. Based on the embodiments in 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.
[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:
[0024] The nondestructive testing tool for sealing of pastry packaging comprises a testing platform 1, at least one testing box 3 is fixedly connected to the top of the testing platform 1, a vacuum pump 4 is fixedly connected to the top of the testing platform 1, the air inlet of the vacuum pump 4 is connected to the inside of the testing box 3 through an air suction pipe 40, an air pressure sensor 37 is installed inside the testing box 3, a one-way valve 42 is installed on the air suction pipe 40, a front door stop 32 is hingedly installed on the front outer wall of the testing box 3 through a hinge 34, a U-shaped limiting rod 31 for limiting the front door stop 32 is hingedly installed on the testing box 3, and a supporting leg 2 is fixedly connected at each of the four corners of the bottom of the testing platform 1. By setting the testing platform 1 and the testing box 3, the sealing of pastry packaging can be conveniently placed and tested. The combination of the vacuum pump 4 and the air pressure sensor 37 makes it possible to test the sealing of pastry packaging by extracting air in the testing box 3 and monitoring the air pressure change, while not causing damage to the product, and effectively reducing the defective rate.
[0025] As a preferred embodiment of the present invention, an observation window 30 is provided on the top of the detection box 3, and the observation window 30 is made of colorless transparent tempered glass. The design of the observation window 30 allows the operator to visually observe the situation in the detection box 3, including the state of the pastry packaging during the detection process, without opening the detection box 3, thereby improving the convenience of use and the efficiency of detection.
[0026] As a preferred embodiment of the present invention, the detection box 3 is divided into a plurality of placement bins 35 by a plurality of partition boards 36, and each placement bin 35 is provided with an air pressure sensor 37. By dividing the internal space of the detection box 3 into a plurality of placement bins 35 by the partition boards 36, a plurality of pastry packages can be tested simultaneously, thereby improving the efficiency of the test. An air pressure sensor 37 is provided in each placement bin 35, which can independently monitor the air pressure changes in each bin, thereby independently judging the sealing of each pastry package.
[0027] As a preferred embodiment of the present invention, the suction pipe 40 is provided with a plurality of shunt pipes 41 respectively connected to each placement bin 35, and a one-way valve 42 is installed on the shunt pipe 41. The design of the shunt pipe 41 enables the vacuum pump 4 to simultaneously evacuate each placement bin 35, thereby ensuring that multiple pastry packages can be tested simultaneously. The one-way valve 42 can prevent airflow backflow, thereby ensuring the accuracy of the test.
[0028] As a preferred embodiment of the present invention, a strip plate 33 for mounting a hinge 34 is fixedly connected to the front outer wall of the detection box 3, and the front outer wall of the front door stop 32 is flush with the outer wall of the strip plate 33. The strip plate 33 provides a stable mounting position for the hinge 34, ensuring that the front door stop 32 can be stably opened and closed.
[0029] As a preferred embodiment of the present invention, a sealing gasket 39 is fixedly connected to the inner ring wall of the front opening 38 formed on the front outer wall of the detection box 3, and when the front door stop 32 is closed, its outer ring wall is tightly fitted with the sealing gasket 39. The design of the sealing gasket enhances the sealing performance of the detection box 3, prevents gas leakage during the detection process, and thus ensures the accuracy of the detection.
[0030] As a preferred embodiment of the present invention, a handle 320 is fixedly connected to the outer wall of the front door stop 32 near the top. The design of the handle 320 allows the operator to open and close the front door stop 32 more conveniently, thereby improving the convenience of operation.
[0031] As a preferred embodiment of the present invention, the U-shaped limiting rod 31 is hinged to the outer wall of the detection box 3 through the hinge shaft 310, and the front door stop 32 is closed. When the U-shaped limiting rod 31 is placed horizontally, its inner wall is tightly fitted with the outer wall of the front door stop 32. The U-shaped limiting rod 31 can effectively limit the front door stop 32 to prevent it from accidentally opening during the detection process. At the same time, the design of the U-shaped limiting rod 31 also allows it to be easily removed from the detection box 3, so as to open the front door stop 32 to take out or put in the pastry package.
[0032] When the utility model of the nondestructive testing tool for sealing of pastry packaging is used, first, the operator places the pastry packaging to be tested into the placement bin 35 of the testing box 3 through the front door stop 32. An air pressure sensor 37 is provided in each placement bin 35 for monitoring the air pressure change in the bin. After placing the pastry packaging, the operator closes the front door stop 32 and limits it with the U-shaped limit rod 31 to prevent the front door stop 32 from accidentally opening during the testing process.
[0033] Next, the operator starts the vacuum pump 4. The air inlet of the vacuum pump 4 is connected to the inside of the detection box 3 through the suction pipe 40, and the suction pipe 40 is provided with a plurality of shunt pipes 41 respectively connected to each placement bin 35. When the vacuum pump 4 is working, it extracts the air in the detection box 3 through the suction pipe 40 and the shunt pipe 41, thereby reducing the air pressure in the placement bin 35. In order to prevent the air flow from flowing back, a one-way valve 42 is installed on each shunt pipe 41.
[0034] During the process of extracting air, the air pressure sensor 37 will monitor the air pressure change in the storage bin 35 in real time. If the sealing performance of the cake packaging is good, the air pressure in the storage bin 35 will continue to drop; if the sealing performance of the cake packaging is defective, the speed of air pressure drop will slow down, and the air pressure may even rise again.
[0035] The operator can visually observe the situation in the detection box 3, including the state of the cake package during the detection process, through the observation window 30. At the same time, the air pressure sensor 37 will feed back real-time air pressure data to the operator so that the operator can judge the sealing of the cake package according to the air pressure change.
[0036] After the test is completed, the operator can open the front door stop 32 and take out the cake packaging. Then, they can classify the cake packaging according to the test results and store cake packaging with good sealing performance and cake packaging with sealing problems separately.
[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
