Description

Technical Field

[0001] The invention belongs to the technical field of can production, and in particular relates to a can sealing detection device and method. Background Art

[0002] Cans are sealable containers made of metal sheets, glass, plastic, cardboard or a combination of some of the above materials. They contain commercial food and are specially treated to achieve commercial sterility. They can be kept at room temperature for a long time without spoiling. This type of packaged food is called canned food. During can production, it is sometimes necessary to test the sealing performance using a sealing detection device.

[0003] In the existing technology, there is a device for detecting the sealing properties of canned corn bottles with application number CN202322488431.4. This application adopts the structural design of the extrusion block, which is not only simple and convenient to operate, but also can perform sealing tests on canned corn of different sizes and models, and can test multiple canned corn at one time. However, when the cans are immersed in water for sealing test, water will enter the inside of the cans with damaged seals. However, some cans with less damage can be repaired after secondary processing, while cans with water in them need to be scrapped, which easily leads to waste of resources. Summary of the Invention

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0053] Specific examples are given below.

[0054] Example 1:

[0055] See also Figures 1 to 8 The present invention provides a can sealing detection device and method thereof, comprising: a base 1, a detection component 4, a sliding component 5, a placement component 6 and a stabilization component 7, and a detection box 2 fixedly installed on the right side of the upper end of the base 1, and a pressure differential tester 3 fixedly installed on the upper end of the detection box 2.

[0056] In this embodiment, when performing a seal test on a can, the can is placed in the placement component 6, and the stability of the can is ensured by the stabilization component 7 to prevent the can from tipping over during the test. The can is sent into the test box 2 for testing through the detection component 4, and the sliding component 5 ensures the stability of the detection component 4 when sliding.

[0057] Example 2:

[0058] Based on Example 1, a detection component 4 and a sliding component 5 are further disclosed. The detection component 4 is installed on the left side of the upper end of the base 1 for detecting cans, and the sliding component 5 is installed on the lower end of the detection component 4 for improving the sliding stability of the detection component 4.

[0059] like Figure 1 、 Figure 2 and Figure 3 As shown, the detection component 4 includes: fixed blocks 401 fixedly installed on the front and rear sides of the upper end of the base 1, screw rods 402 are rotatably connected between the fixed blocks 401, sliders 403 are rotatably connected between the screw rods 402, a cover plate 404 is fixedly installed on the side of the slider 403 close to the central axis, a detection frame 405 is fixedly installed on the middle of the right side of the cover plate 404, a fitting block 406 is fixedly installed on the right outer end of the cover plate 404, and a fitting groove 407 is provided on the left side of the detection box 2. The sliding component 5 includes: a connecting strip 501 fixedly installed on the upper side of the front and rear ends of the detection frame 405, a ball bearing 502 is rotatably connected to the lower end of the connecting strip 501, a sliding groove 503 is provided on the left side of the upper end of the base 1, a movable block 504 is fixedly installed on the lower end of the cover plate 404, and a roller 505 is rotatably connected to the lower end of the movable block 504.

[0060] In this embodiment, after the can is placed in the placement component 6, the motor is started to drive the screw rod 402 on the fixed block 401 to rotate, and the rotation of the screw rod 402 drives the slider 403 to slide, and the sliding of the slider 403 drives the cover plate 404 to slide, driving the cover plate 404 to fit with the detection box 2, and synchronously drives the detection frame 405 to slide into the detection box 2, and then starts the pressure difference tester 3. The gas nozzle of the pressure difference tester 3 is installed inside the detection box 2. The pressure difference tester 3 generates negative pressure to extract the gas in the detection box 2. According to the total amount extracted and the extraction rate, it is judged whether the can is damaged, thereby detecting the sealing of the can. When the cover plate 404 is fitted with the detection box 2, the interlocking block 406 will be synchronously inserted into the interlocking groove 407 to ensure the tightness of the cover plate 404 and the detection box 2. At the same time, the screw rod 402 drives the slider 403 to slide, so that the cover plate 404 and the detection box 2 fit more tightly. When the slider 403 slides and drives the cover plate 404 to slide, the movable block 504 will also slide with the cover plate 404. At the same time, the lower end of the roller 505 will fit with the slide groove 503. As the movable block 504 slides, the roller 505 will also roll in the slide groove 503, thereby improving the stability of the cover plate 404 when sliding. At the same time, it is prevented that the gravity of the cover plate 404 and the detection frame 405 is both borne on the screw rod 402, thereby preventing the screw rod 402 from being damaged by excessive force. At the same time, when the detection frame 405 slides, the lap bar 501 cooperates with the ball 502 to slide in the detection box 2, further improving the stability of the cover plate 404 and the detection frame 405 when sliding.

[0061] Example 3:

[0062] On the basis of Example 1, a placement component 6 is further disclosed. The placement component 6 is installed inside the detection component 4 and is used to place the can into the detection component 4.

[0064] 605 , and then the second placement box 602 is slid so that the handle 604 on the first placement box 601 is completely inserted into the card slot 605 , thereby completing the assembly of the first placement box 601 and the second placement box 602 . At the same time, the through slot 606 at the lower end of the second placement box 602 facilitates the communication between the first placement box 601 and the detection box 2 , thereby facilitating the detection and simultaneous detection of multiple cans, thereby improving the detection efficiency and facilitating the removal of the first placement box 601 and the second placement box 602 from the detection frame 405 , thereby preventing the detection frame 405 from being contaminated by leakage during the can detection.

As the can is inserted, the clamping plates 704 will be squeezed to both sides, pushing the push block 702 to slide into the sleeve 701 to fix the can. At the same time, the spring 703 will push the clamping plates 704 to fit the can, ensuring the stability of the can when placed, avoiding damage caused by the can tipping over, and affecting subsequent sales.
