Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of sealing detection devices, specifically relating to a sealing detection device for a protein tank lid. Background Technology
[0002] Protein can lids are mainly used for sealing and moisture prevention, and are commonly found in the packaging of products such as milk powder and protein powder. They are mainly made of food-grade plastic or tinplate and have functions such as anti-theft, easy tearing, and sealing. During the production process of protein can lids, sealing tests are required. The sealing tests for protein can lids are mostly carried out using the positive pressure method and the water bath method.
[0003] Currently, existing protein tank lids require sealing tests during production. However, due to their unique structure and relatively soft material, the lids are prone to deformation or even detachment during testing as internal pressure gradually increases, making it difficult to guarantee their sealing performance. Therefore, we propose a sealing test device for protein tank lids. Utility Model Content
[0004] The purpose of this invention is to provide a sealing detection device for the high lid of a protein tank, so as to solve the existing problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing detection device for a protein tank with a high lid, comprising a base, a tray, and a pressure cap. A support frame is fixedly installed on one side of the top of the base. A first electric push rod is embedded in the top end of the support frame. A U-shaped frame is fixedly installed at the bottom of the first electric push rod. A tray is fixedly installed at the bottom inside the U-shaped frame. A second electric push rod is embedded in the inner top wall of the U-shaped frame. A pressure cap is installed at the bottom of the second electric push rod. An inner retaining ring is provided on the inner top wall of the pressure cap. A sealing ring is fitted on the outer surface of the inner retaining ring. The inner retaining ring and the pressure cap... An annular rubber sleeve is provided between the inner walls of the cover and the inner wall of the cover. The annular rubber sleeve is fixed and sealed to the inner wall of the cover. An annular groove is provided between the annular rubber sleeve and the inner retaining ring. A fixing ring is provided inside the annular rubber sleeve. A connecting post is provided at equal intervals around the bottom of the fixing ring. An arc-shaped rod is movably connected to the outer circumference of the connecting post. A pressure plate is provided at the end of the arc-shaped rod. An arc-shaped groove is opened in the middle of the arc-shaped rod. An annular worm gear is also provided inside the annular rubber sleeve. A moving post is installed at equal intervals around the top of the annular worm gear. The moving post extends into the interior of the arc-shaped groove and is slidably connected to its inner wall.
[0006] Preferably, a transmission box is installed on the outer side of the pressure cap, and a worm gear is movably connected to the outer side of the transmission box via a sealed bearing. The worm gear extends into the interior of the pressure cap and meshes with an annular worm wheel. A knob is installed on one outer end of the worm gear.
[0007] Preferably, an air pump is fixedly installed on one side of the top of the U-shaped frame, the bottom end of the air pump extends into the interior of the pressure cap, and the air injection port opened inside the pressure cap is sealed and connected to the air pump through a conduit. A solenoid valve is provided at the connection between the air injection port and the conduit.
[0008] Preferably, a pressure sensor is fixedly installed on the inner top wall of the pressure cap inside the inner retaining ring, and the pressure sensor is fixedly installed on one side of the inner top wall of the pressure cap.
[0009] Preferably, a water tank is fixedly installed at the top center of the base, and the water tank is located directly below the U-shaped frame.
[0010] Preferably, the bottom of the tray has through holes, which are evenly distributed on the bottom of the tray.
[0011] Preferably, a control panel is fixedly installed at one top end of the support frame, and the control panel is fixedly installed at one top end of the support frame by means of embedding.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. By using a U-shaped frame, a pressure cap and a tray are set at the top and bottom of the frame. The pressure cap is pushed down by a second electric push rod. During testing, the tray can support the protein tank lid to prevent it from falling off and ensure its stability. The inner retaining ring with a sealing ring and an annular rubber sleeve, under the action of the pressure plate, ensures the sealing between the protein tank lid and the pressure cap, thereby ensuring the accuracy of the test.
[0014] 2. By using a worm gear and an annular turbine to drive the actuating column to rotate, which in turn rotates the arc-shaped rod, the pressure plate pushes the annular sealing sleeve to apply pressure to the outer circumference of the protein tank lid. This ensures its sealing and stability. The non-reverse transmission between the worm gear and the annular worm wheel ensures the stability of the pressure plate and prevents loosening during the testing process, which could lead to air leakage.

[0020] Please see Figure 1-3 This utility model provides a sealing detection device for a protein tank lid: it includes a base 1, a tray 7, and a pressure cap 9. A support frame 3 is fixedly installed on one side of the top of the base 1. A first electric push rod 5 is embedded in the top end of the support frame 3. A U-shaped frame 6 is fixedly installed at the bottom of the first electric push rod 5. The tray 7 is fixedly installed at the bottom of the inner side of the U-shaped frame 6. A second electric push rod 25 is embedded in the inner top wall of the U-shaped frame 6. The pressure cap 9 is installed at the bottom of the second electric push rod 25. An inner retaining ring 13 is provided on the inner top wall of the pressure cap 9. A sealing ring is sleeved on the outer surface of the inner retaining ring 13. An annular rubber sleeve is provided between the inner retaining ring 13 and the inner wall of the pressure cap 9. 15. The annular rubber sleeve 15 is fixed and sealed to the inner wall of the pressure cap 9. An annular groove 14 is provided between the annular rubber sleeve 15 and the inner retaining ring 13. A fixing ring 18 is provided inside the annular rubber sleeve 15. A connecting post 19 is provided at equal intervals at the bottom of the fixing ring 18. An arc rod 20 is movably connected to the outer periphery of the connecting post 19. A pressure plate 22 is provided at the end of the arc rod 20. An arc groove 21 is opened in the middle of the arc rod 20. An annular worm gear 23 is also provided inside the annular rubber sleeve 15. A toggle post 24 is installed at equal intervals on the top of the annular worm gear 23. The toggle post 24 extends into the interior of the arc groove 21 and slides in connection with its inner wall.
[0021] Specifically, a transmission box is installed on the outer side of the pressure cover 9, and a worm gear 17 is movably connected to the outer side of the transmission box via a sealed bearing. The worm gear 17 extends into the interior of the pressure cover 9 and meshes with the annular worm wheel 23. A knob 16 is installed on the outer end of the worm gear 17.
[0022] Specifically, an air pump 10 is fixedly installed on one side of the top of the U-shaped frame 6. The bottom end of the air pump 10 extends into the interior of the pressure cap 9. The air injection port 11 inside the pressure cap 9 is sealed and connected to the air pump 10 through a conduit. A solenoid valve is provided at the connection between the air injection port 11 and the conduit.
[0023] Specifically, a pressure sensor 12 is fixedly installed on the inner top wall of the pressure cap 9 inside the inner retaining ring 13. The pressure sensor 12 is fixedly installed on one side of the inner top wall of the pressure cap 9.
[0024] Specifically, a water tank 2 is fixedly installed at the top center of the base 1, and the water tank 2 is located directly below the U-shaped frame 6.
[0025] Specifically, the bottom of the tray 7 is provided with through holes 8, which are evenly distributed on the bottom of the tray 7.
[0026] Specifically, a control panel 4 is fixedly installed at one top end of the support frame 3. The control panel 4 is fixedly installed at one top end of the support frame 3 by means of inlay.
[0027] In this embodiment, during use, the opening of the protein tank lid is inserted upwards into the bottom end of the pressure cap 9, with its edge inserted into the annular groove 14. A sealing connection is formed with the sealing ring on the outer periphery of the inner retaining ring 13. Then, the knob 16 is rotated from the outside, causing the worm gear 17 to rotate. The worm gear 17 then rotates the annular worm wheel 23, causing the annular worm wheel 23 to rotate the actuating pin 24 slightly. Since the actuating pin 24 is located inside the arc-shaped groove 21, the actuating pin 24, in conjunction with the arc-shaped groove 21, drives the arc-shaped rod 20 to rotate around the connecting pin 19. This causes the other end of the arc-shaped rod 20 to move towards the center position along with the pressure plate 22, thereby lifting the annular rubber sleeve 15 and pressing it tightly against the outer surface of the protein tank lid. The edges are rounded to ensure a tight seal between the protein tank lid and the pressure cap 9. Then, the pressure cap 9 is pushed down by the second electric push rod 25 so that the bottom of the protein tank lid is inside the tray 7. The first electric push rod 5 then pushes the U-shaped frame 6 to move the pressure cap 9 down so that the pressure cap 9 is submerged in the liquid in the water tank 2. Then, the air pump 10 injects air into the cavity formed between the pressure cap 9 and the protein tank lid through the air injection port 11. The air pressure sensor 12 monitors the changes in internal air pressure and whether air bubbles are generated in the water tank 2. If air bubbles are generated, the protein tank lid is not properly sealed. If the value monitored by the air pressure sensor 12 is stable and no air bubbles are generated after the air injection is stopped, the protein tank lid is properly sealed.
