Description

Technical Field

[0001] The invention relates to the technical field of sealing test, in particular to a beef packaging sealing detection device. Background Art

[0002] The main purpose of beef packaging sealing test is to keep food fresh and hygienic, extend the shelf life, and reduce the risk of food corruption and deterioration. By testing the sealing of the package, it can be ensured that the beef will not be contaminated by the external environment during transportation, storage and sales, thus ensuring food safety.

[0003] The specific detection method used in the prior art is to simulate the pressure changes that the product may encounter during actual use through a negative pressure sealing tester to detect the sealing performance of the package. The specific detection scheme includes observing whether the bag expands after vacuuming, but this scheme requires manual visual observation, which has large errors and cannot efficiently detect and discover tiny air leaks. On the other hand, the traditional detection scheme also completes the detection by observing whether bubbles are generated in the immersed liquid, but this scheme can only be applied to the detection of packaging materials with small amounts of material, which is inefficient. Once a leaky beef package is detected, the liquid will penetrate into the interior, which will cause the internal ingredients to be unable to be further processed and eaten, resulting in waste.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: a beef packaging sealing detection device, comprising a detection device body, the detection device body comprising a detection sleeve 1, a lifting mechanism 6, a switching assembly 7 and a supporting assembly 8, a top plate 3 is integrally formed on the inner top of the detection sleeve 1, a vacuum pump 4 is screwed on the surface of the top plate 3, a bracket 10 is welded to the bottom of the top plate 3, a pressure module 11 is embedded at the bottom of the bracket 10, a lifting mechanism 6 is inserted into the bottom end of the detection sleeve 1, a supporting assembly 8 is welded to the top of the lifting mechanism 6, an elastic sheet 22 is mounted inside the supporting structure, and the elastic sheet 22 is made of rubber material as a whole, an extension plate 5 is welded to the side of the detection sleeve 1, a switching assembly 7 is welded to the bottom of the extension plate 5, a push rod 25 is welded in the middle of the switching assembly 7, the push rod 25 passes through the middle of the lifting mechanism 6, and the end of the push rod 25 is used to lean against the inner side of the supporting assembly 8, and a feed port 2 is opened on the side of the detection sleeve 1. The beef packaging sealing detection device is used to detect whether there is air leakage in non-sealed packaging products.

[0029] The present invention is only applicable to the detection of beef packaging in a non-vacuum state. After the detection sleeve 1 is vacuumed, the beef packaging is detected with the help of the pressure module 11 on the top, so that the change state of the value of the pressure module 11 can be judged after the beef packaging leaks, so as to judge the degree of leakage of the beef packaging, so as to obtain more detailed sealing data. During the specific detection, the beef packaging bag to be tested is put from the feed port 2 into the interior of the detection sleeve 1 through an external conveying device, and falls into the top of the support component 8, and then the motor 27 can be started to drive the lifting mechanism 6 and the support component 8 to lift the beef packaging. The bag is lifted until it is close to the top plate 3 at the top, and the surface of the beef packaging bag is pressed against the bottom of the pressure module 11. At this time, the vacuum pump 4 is started to evacuate the cavity where the beef packaging bag is located. At this time, the docking block 30 at the bottom completes self-locking. By observing the pressure changes displayed by the pressure module 11, it is determined whether the beef packaging bag has leakage. At the same time, the degree of leakage is also determined after leakage occurs. After the detection is completed, the lifting mechanism 6 can be controlled to move downward, and finally the support assembly 8 can be tilted upward with the help of the switching assembly 7 at the bottom, and the beef packaging bag on the inside that has completed the inspection can be discharged to the outside with the help of the convex support assembly 8.

[0030] In this embodiment, the switching assembly 7 includes a bottom plate 24 and a top rod 25, the top rod 25 is welded to the middle position of the surface of the bottom plate 24, the top of the top rod 25 is embedded with a bottom magnetic sheet 26, the surface of the extension plate 5 is screwed with a motor 27, the output end of the motor 27 is inserted with a screw rod 28, and one end of the surface of the bottom plate 24 is welded with a guide rod 29. The screw rod 28 and the guide rod 29 are respectively installed on both sides of the top rod 25, and the end of the screw rod 28 is embedded in the surface of the bottom plate 24 through a support bearing 23, and the top rod 25 coincides with the central axis of the detection sleeve 1. Only vacuum treatment is required to complete the detection process, and there is no need to immerse it in the liquid. After detecting the leaking beef package, it is only necessary to take out the beef package, and then replace the packaging bag to restart the subsequent processing process, avoiding waste, and the entire detection process is more efficient, and liquid adhesion contamination on the surface of the beef package is also avoided.

[0031] Specifically, during the inspection, the beef packaging bag will be placed on the support assembly 8 and against the bottom of the pressure module 11. Therefore, when the beef packaging bag has good sealing and no air leakage occurs, the cavity between the top plate 3 and the sealing plate 18 will be evacuated through the air suction hole 9. The beef packaging bag will not leak, but will expand due to the drop in external air pressure. The expansion will cause the pressure against the pressure module 11 to increase rapidly and stabilize at a fixed value. At this time, the beef packaging bag can be judged to have no air leakage by observing that the value of the pressure module 11 increases and remains stable after the increase.

[0032] When the beef packaging bag has a serious air leak, the air inside the beef packaging bag will be simultaneously extracted due to the above-mentioned vacuum process. At this time, the beef packaging bag will not expand, so the pressure module 11 will not detect a rapid increase in the pressure against the bag. If the beef packaging bag has a slight air leak, it will expand at the moment of vacuuming, and the pressure data detected by the pressure module 11 will increase. However, the air inside the beef packaging bag will continue to leak subsequently, causing the pressure data against the pressure module 11 to slowly decrease, ultimately achieving the effect of judging whether the beef packaging bag is leaking and the degree of leakage.

[0033] In this embodiment, the lifting mechanism 6 includes a lifting sleeve 14 and an inner sleeve 19, a sealing plate 18 is integrally formed between the inner sleeve 19 and the lifting sleeve 14, and a through hole 33 is provided in the middle of the bottom of the inner sleeve 19. A sealing ring 36 is attached to the edge of the sealing plate 18, and the sealing ring 36 is attached to the inner wall of the detection sleeve 1. A gap is provided between the side of the inner sleeve 19 and the inner wall of the detection sleeve 1, and a lifting plate 15 is welded to the outer bottom of the lifting sleeve 14. A threaded hole 16 or a guide hole 17 is provided at the end of the surface of the lifting plate 15, the screw rod 28 passes through the inside of the threaded hole 16, and the guide rod 29 passes through the inside of the guide hole 17, and the inside of the lifting sleeve 14 is connected to the inside of the inner sleeve 19 through the through hole 33.

[0034] Specifically, after starting the motor 27, the screw rod 28 rotates to cooperate with the threaded hole 16 to drive the entire lifting plate 15 to perform lifting and lowering movements, thereby driving the lifting sleeve 14 and the top inner sleeve 19 and the support assembly 8 to perform lifting and lowering movements. The elastic sheet 22 in the support assembly 8 will automatically switch between the convex and concave states in cooperation with the switching assembly 7 at the bottom during the lifting process, so as to ensure that the incoming beef packaging bag can be stably supported and lifted, and subsequently automatically slide out.

[0035] In this embodiment, the support assembly 8 includes an elastic sheet 22 and a docking block 30. A support ring 21 is welded to the top of the inner sleeve 19. The edge of the elastic sheet 22 is embedded in the inner wall of the support ring 21, and the elastic sheet 22 is a hemispherical structure as a whole. An air extraction hole 9 is provided on the surface of the top plate 3. The vacuum pump 4 is partially connected to the air extraction hole 9 through a pipeline. A lower hanging rod 12 is also welded to the bottom of the top plate 3. An arc-shaped sheet 13 is integrally formed at the bottom end of the lower hanging rod 12. The arc-shaped sheet 13 is used to press against the surface of the elastic sheet 22 from above. A docking block 30 is attached to the bottom of the elastic sheet 22. A top magnetic sheet 35 is embedded in the bottom of the docking block 30. Telescopic grooves 32 are provided at both ends of the docking block 30. A plug-in column 31 is embedded in the interior of the telescopic groove 32. A docking groove 34 is provided on the inner wall of the through hole 33. A connecting channel 20 is provided on the inner side of the bottom of the inner sleeve 19, and the connecting channel 20 is connected to the inside of the docking groove 34. A gap is provided between the side of the support ring 21 and the inner wall of the detection sleeve 1. The length of the plug-in column 31 is the same as the depth of the telescopic groove 32, and the depth of the docking groove 34 is less than the length of the plug-in column 31. The edge of the docking block 30 is aligned with the inner wall of the through hole 33. The beef package is transported by the internal support assembly 8, and a concave detection area and a convex discharge area can be provided during the lifting and moving process, so that each beef package can automatically realize the discharge process during the lifting and moving process of the support mechanism, with a high degree of automation. The elastic sheet 22 in the support assembly 8 also achieves a self-locking effect by virtue of the internal vacuum state during detection, which can prevent the elastic sheet 22 from being affected by the vacuum and causing it to bulge upward and finally interfere with the pressure detection process.

[0036] Specifically, when the lifting mechanism 6 controls the support assembly 8 to move downward, the docking block 30 at the bottom will be pressed against the bottom magnetic sheet 26, and then supported by the column, the elastic sheet 22 can be pushed upward from the middle, so that the elastic sheet 22 becomes an upward convex state. At this time, the beef packaging bag after the top is inspected can slide toward the side from the elastic sheet 22 in the convex state. After the discharge is completed, the lifting mechanism 6 controls the support assembly 8 to move upward. At this time, the bottom magnetic sheet 26 has been adsorbed with the top magnetic sheet 35. Therefore, the adsorption force will apply a pulling force from the middle position of the bottom of the elastic sheet 22, and then when the lifting mechanism 6 pushes the elastic sheet 22 upward from the support ring 21, the bottom of the elastic sheet 22 is adsorbed and fixed. Finally, the elastic sheet 22 is switched from a convex state to a concave state, and in this state, the external beef packaging bag passes through the feed port 2 and falls onto the concave elastic sheet 22. During subsequent inspection, the cavity at the bottom of the top plate 3 is evacuated. At this time, the docking block 30 is in a concave state and will be embedded in the through hole 33. Therefore, the vacuuming will simultaneously draw the plug-in column 31 inside the telescopic groove 32 into the docking groove 34 with the help of the connecting channel 20. At the same time, the arc-shaped sheet 13 on the top is also pressed on the edge of the top of the elastic sheet 22 to ensure that the elastic sheet 22 will not warp upward during the vacuuming process, so that it always remains in a concave state, so that the beef packaging bag is always in the middle position of the elastic sheet 22 to facilitate contact with the pressure module 11.
