Description

Technical Field

[0001] This invention belongs to the field of functional bottle cap manufacturing technology, specifically relating to a quality inspection device and method for aluminum foil sealing of functional bottle caps. Background Technology

[0002] In the food and health product industry, premixed liquid forms, such as beverages and oral liquids, are frequently used. However, the biggest problem with premixed liquid foods and health products is their susceptibility to external factors that cause them to lose their activity and deteriorate, such as light, heat, oxygen, and ultraviolet radiation. Therefore, preservatives, freshness-preserving agents, and stabilizers need to be added. Even so, the shelf life of premixed liquids is still shorter than that of solids. Furthermore, the taste of liquid preparations changes due to time and environmental influences during storage, which also restricts the development of many food products, such as anthocyanin-based, vitamin-based, and probiotic beverages, where the activity retention period is significantly shortened after mixing with water. With the continuous improvement of people's living standards, people are increasingly pursuing healthy bottled beverages. If a beverage bottle cap could be designed to store solid ingredients and allow for on-demand preparation, the nutritional ingredients would be isolated from water before use, maintaining the activity of the raw materials. This on-demand preparation would allow manufacturers to avoid using preservatives and stabilizers, and users would receive a safe and reliable product. This design concept has gained widespread acceptance.

[0003] Therefore, our company has designed a large-size functional bottle cap, such as... Figure 2 As shown, the large-size functional bottle cap 6 mainly consists of a lower cap component 61, an upper cap component 62, and an inner container 63 for storing the contents. An aluminum foil sheet 64 is installed at the bottom of the lower cap component 61. The upper cap component 62 protects the inner container 63. The contents can be released by pressing down on the aluminum foil sheet 64. To improve the load-bearing capacity of the aluminum foil sheet 64, our company innovatively added a sealing and anti-detachment structure at its connection with the lower cap component 61. In the production process of this type of functional bottle cap, it is necessary to ensure the sealing performance of the aluminum foil sheet to prevent the contents from deteriorating or clumping; on the other hand, the dynamic compressive strength of the aluminum foil sheet needs to be within the design standard range. Insufficient strength will lead to accidental damage to the aluminum foil sheet, while excessive strength will make it difficult to break, affecting subsequent use.

[0004] The existing quality inspection device for aluminum foil sealing of functional bottle caps has shortcomings. First, it cannot simultaneously meet the testing requirements for the sealing performance and dynamic compressive strength of the aluminum foil after sealing. Second, it cannot simulate the sealing operation of aluminum foil of different thicknesses before testing, which makes it difficult for R&D personnel to select aluminum foil of appropriate thickness to seal functional bottle caps.

[0005] In view of this, the inventors hope to optimize and improve the existing quality inspection device for aluminum foil sealing of functional bottle caps. Summary of the Invention

The electromagnetic induction heating coil 320 heats the aluminum foil 64 instantaneously through electromagnetic induction, causing it to fuse into the concave sealing groove 616, forming an anti-detachment sealing structure.

[0038] like Figure 8 and Figure 9 As shown, the airtightness testing component 4 includes a third motor 401, a third rotating plate 402, a positioning seat 403, a suspension column 404, a steering motor 405, a belt drive component 406, a pressure cap 407, a sealing ring 408, an air guide channel 409, an air pump 410, and a pressure sensor 411. The output end of the third motor 401 is equipped with the third rotating plate 402. The lower side of the third rotating plate 402 is movably supported by the positioning seat 403 on the suspension column 404. The pressure cap 407 is installed on the bottom side of the suspension column 404. 07. A sealing ring 408 is provided on the lower side of the pressure cap 407 to cooperate with the upper port of the inner tube 611. A steering motor 405 and an air pump 410 are installed on the third rotating plate. The output shaft of the steering motor 405 is connected to the suspension column 404 via a belt drive 406. The air pump 410 inflates the area inside the sealing ring 408 through the air guide channel 409 jointly opened by the suspension column 404 and the pressure cap 407. A pressure sensor 411 is installed in the area of ​​the pressure cap 407 located inside the sealing ring 408.

[0039] The working principle of the airtightness detection component 4: The third motor 401 drives the third rotating plate 402 to rotate, which in turn moves the positioning seat 403 and the suspension column 404. The steering motor 405 drives the suspension column 404 to rotate through the belt drive component 406, so that the pressure cap 407 presses against the upper port of the inner tube 611, and the sealing ring 408 achieves a seal. The air pump 410 inflates the bottle mouth sealing area 615 through the air guide channel 409, and the air pressure sensor 411 detects the pressure change in real time to determine the airtightness.

[0040] like Figure 10 As shown, the dynamic load compressive strength testing component 5 includes a hammer impact box 51, a flipping drive mechanism 52, and a self-locking hammer impact member 53. The hammer impact box 51 is externally mounted with a flipping drive mechanism 52 that provides movable support and drives it to flip. The hammer impact box 51 is internally restricted by a self-locking hammer impact member 53.

[0041] like Figures 11-12 As shown, the hammering box 51 includes a rectangular box 511 with an open bottom. The inner wall of the rectangular box 511 is provided with a limiting protrusion 512, and the top plate of the rectangular box 511 has an elliptical locking hole 513. The flipping drive mechanism 52 includes a vertical plate 521, a positioning shaft 522, a transmission shaft 523, a second flipping motor 524, a driving bevel gear 525, and a driven bevel gear 526.

The positioning shaft 522 and the transmission shaft 523 are symmetrically fixed on both sides of the rectangular box 511. The output end of the second flipping motor 524 is equipped with the driving bevel gear 525, and the outer end of the transmission shaft 523 is equipped with the driven bevel gear 526 that meshes with the driving bevel gear 525.

[0042] The working principle of the flipping drive mechanism 52: The second flipping motor 524 drives the active bevel gear 525 to rotate, the active bevel gear 525 drives the driven bevel gear 526 to rotate, and the driven bevel gear 526 drives the rectangular box 511 to flip through the transmission shaft 523, so as to realize the slow flipping of the hammer box 51, so that the self-locking hammering component 53 can automatically reset after hammering.

A first pressure relief hole 536 is opened on the upper side plate of the pressure tube 533, and multiple second pressure relief holes 537 are opened on the side end of the pressure tube 533.

[0044] The working principle of the self-locking hammer impact component 53: The self-locking motor 534 drives the elliptical locking block 535 to rotate. When the elliptical locking block 535 aligns with the elliptical locking hole 513, the hammer base 531 can fall freely along the inner cavity of the rectangular box 511, and the hammer impact tube 533 impacts the aluminum foil sheet 64. The load on the hammer base 531 is adjusted by injecting water or sand into the adjustment chamber, and the lower and upper limits of the load are set for qualification judgment. After the self-locking hammer impact component 53 slides back to its original position as the hammer impact box 51 flips, the elliptical locking block 535 first passes through the elliptical locking hole 513, and then rotates 90 degrees to complete the self-locking. The hammer base 531 is equipped with a battery that provides power to the self-locking motor 534.

[0045] like Figure 14 As shown, it also includes a controller 7, which is connected to the cover clamping assembly 1, the cover feeding assembly 2, the aluminum foil heat sealing assembly 3, the airtightness detection assembly 4, and the dynamic load compressive strength detection assembly 5, respectively, to control the coordinated operation of each assembly.

After locking, the first motor 101 drives the first rotating head 102 to transfer the lower cover component 61 to the heat sealing station. S2, Aluminum Foil Heat Sealing The aluminum foil heat sealing assembly 3 positions the aluminum foil 64 at the anti-detachment ring 617; the aluminum foil 64 is fused to the concave sealing groove 616 by electromagnetic induction instantaneous heating to form an anti-detachment sealing structure; S3, Air tightness test The cap 407 of the air tightness detection component 4 presses the upper port of the inner tube 611 with the sealing ring 408; the air pump 410 inflates the bottle mouth sealing area 615 through the air guide channel 409, and the air pressure sensor 411 detects the pressure change in real time. S4.
