Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a sealing detection equipment. Background Art

[0002] As a sealed container, plastic bottles need to be tested for sealing after they are produced to determine whether the plastic bottles have defects such as small cracks or holes due to processing and other reasons, which may lead to substandard quality of the plastic bottles. However, most of the plastic bottles nowadays are tested for sealing by immersion. The plastic bottles are immersed in water to see whether bubbles are generated in the water to determine whether the sealing of the plastic bottles is qualified. However, when the plastic bottles are large in size, it is difficult to immerse the plastic bottles in water due to the buoyancy generated by the plastic bottles. The operation process is cumbersome, and after the plastic bottles are tested, the water on their surface will drip onto the ground at will, causing the floor in the production workshop to be wet, which can easily cause workers to fall. Utility Model Content

[0003] The utility model discloses a sealing detection device, which solves the problems that it is difficult to immerse a large plastic bottle in water, the operation process is cumbersome, and after the plastic bottle is tested, water on the plastic bottle will drip onto the ground at will.

[0004] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions:

[0005] A sealing detection device includes a base, a connecting tube is provided above the base, an electric telescopic rod is fixed to the bottom of the connecting tube, and a perforated plate is fixed to the telescopic end of the electric telescopic rod; a liftable sealing plate is provided above the connecting tube, a fixed vertical pipe is passed through the bottom of the sealing plate, an air pump No. 1 is fixed to the top of the sealing plate, the exhaust end of the air pump No. 1 is connected to a fixed pipe connected to the vertical pipe, and a No. 1 air pressure gauge is installed on the fixed pipe; a hydraulic rod for driving the sealing plate to rise and fall is provided above the base.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] After placing the large plastic bottle in the connecting cylinder, start the electric telescopic rod to drive the perforated plate to move upward so that the bottle mouth of the large plastic bottle is flush with the top of the connecting cylinder; then start the hydraulic rod to drive the sealing plate to move downward so that the bottom of the sealing plate contacts the connecting cylinder and the top of the bottle mouth of the large plastic bottle, thereby sealing the connecting cylinder and the inside of the large plastic bottle; and after the vertical pipe moves downward with the sealing plate, it is inserted into the large plastic bottle through the bottle mouth of the large plastic bottle, and then start the No. 1 air pump to transport the gas into the vertical pipe through the fixed pipe, and the vertical pipe then transports the gas into the large plastic bottle, thereby increasing the pressure inside the large plastic bottle; then turn off the No. 1 air pump, and the staff observes the No. 1 air pump. Whether the value displayed on the pressure gauge decreases, when the value on the No. 1 pressure gauge decreases, it indicates that there are small cracks or holes in the large plastic bottle. When the value on the No. 1 pressure gauge remains unchanged, it indicates that the large plastic bottle has no defects of small cracks or holes. After the inspection of the large plastic bottle is completed, the sealing plate is restored, and then the large plastic bottle can be taken out of the connecting tube. The utility model adopts a method of injecting gas into the large plastic bottle and observing the pressure in the large plastic bottle to perform a sealing test on the large plastic bottle.

The exhaust pipes 81 correspond to the axis of the group of openings 31 respectively, and the No. 2 gas Pump 83, the exhaust end of the No. 2 air pump 83 is connected to the air supply pipe 84, the No. 2 air pressure gauge 11 is installed on the air supply pipe 84, and the air supply pipe 84 is connected to a rubber tube 85. The other end of the rubber tube 85 is connected to a long tube 86 that penetrates the sealing plate 6 and is connected to the top of the annular shell 8. The diameter of the annular shell 8 is the same as the inner diameter of the connecting tube 2. A No. 3 automatic telescopic rod 82 is fixed to the top of the sealing plate 6. The telescopic end of the No. 3 automatic telescopic rod 82 penetrates the bottom of the sealing plate 6 and is connected to the top of the annular shell 8. After the perforated plate 3 is moved upward, the carrying ring 34 is moved upward along with it through the second automatic telescopic rod 33. Then, the staff can respectively pass a plurality of small plastic bottles through a group of openings 31, and then make the carrying ring 34 support the bottom of the small plastic bottles so that the top of the bottle mouth of the small plastic bottle is flush with the top of the connecting tube 2; then, the sealing plate 6 is moved downward to contact the top of the connecting tube 2, and the third automatic telescopic rod 82 is started (the number of the third automatic telescopic rod 82 is at least two) to move the annular shell 8 downward and enter the connecting tube 2, so that a group of exhaust pipes 81 are respectively inserted into a group of small plastic bottles, and then the second air pump 83 is started (the second air pump 83 is fixed to the top of the sealing plate 6 through the vertical rod, as shown in FIG. Figure 1 ), the gas passes through the rubber tube 85 into the long tube 86, and then the gas enters the annular shell 8 and enters the small plastic bottle through the exhaust pipe 81; after closing the No. 2 air pump 83, the staff can check whether there are cracks or holes in a group of small plastic bottles through the value displayed on the No. 2 pressure gauge 11.

[0017] like Figure 1 As shown, the side of the hydraulic rod 7 away from the connecting tube 2 is provided with a support plate 71 fixed to the top of the base 1. A bearing plate 72 connected to the fixed end of the hydraulic rod 7 is fixed to the support plate 71. The side of the support plate 71 close to the hydraulic rod 7 is slidably connected to a lifting plate 73 fixed to the telescopic end of the hydraulic rod 7. The lifting plate 73 is fixed to one side of the sealing plate 6. After the hydraulic rod 7 is activated, the telescopic end of the hydraulic rod 7 can drive the sealing plate 6 to move upward or downward via the lifting plate 73.

An inflation ring 32 is fixed to the inside of the opening 31, and the inflation ring 32 is connected to the hose 41 through a connecting tube. Depending on the size of the small plastic bottle, after starting the No. 3 air pump 4, gas is allowed to enter the connecting tube (the connecting tube is not shown) through the hose 41, and then the inflation ring 32 is inflated. After the inflation ring 32 expands, it clamps the small plastic bottle and cooperates with the supporting ring 34 to complete the fixation of the small plastic bottle. And later, when the small plastic bottle is tested for sealing, the No. 2 automatic telescopic rod 33 can be activated to move the supporting ring 34 downward, separating the supporting ring 34 from the bottom of the small plastic bottle, so as to facilitate the detection of defects such as holes in the bottom of the small plastic bottle.

[0019] like Figure 1 and Figure 2 As shown, a group of gas sensors 5 are embedded on the inner wall of the connecting tube 2; an annular groove 26 is provided on the top of the connecting tube 2, and a sealing ring 64 that matches the groove 26 is fixed to the bottom of the sealing plate 6. The suction ends of the No. 1 air pump 62 and the No. 2 air pump 83 can be connected to nitrogen bottles respectively, and nitrogen can be filled into the large plastic bottle or the small plastic bottle; when there are defects such as cracks or holes on the plastic bottle, nitrogen will leak out of the plastic bottle, and after the gas sensor 5 detects it, it will be displayed on the external display screen; the staff can combine the pressure detection of whether there is a leak point in the plastic bottle with the nitrogen detection method to improve the accuracy of the detection; when the sealing plate 6 contacts the top of the connecting tube 2, the sealing ring 64 enters the groove 26, which can effectively seal the connecting tube 2.

[0020] like Figure 2 As shown, a blower 22 is fixed to the bottom of the connecting tube 2, and the exhaust end of the blower 22 is connected to the connecting shell 23 located below the carrying ring 34, and an exhaust hole is provided on the top of the connecting shell 23. When nitrogen is used in combination with pressure to test plastic bottles, if there is a leak in the plastic bottle, causing nitrogen to leak into the connecting tube 2, after the subsequent plastic bottle testing is completed, the blower 22 can be started to allow the air to be discharged through the exhaust hole on the connecting shell 23, and then the nitrogen in the connecting tube 2 can be blown out, so as to quickly carry out the next round of testing on the subsequent plastic bottles; the connecting shell 23 is provided with a circular hole for the main body of the electric telescopic rod 21 and the hose 41 to pass through, and the air inlet end of the blower 22 and the exhaust end of the No. 3 air pump 4 both pass through the outer wall of the connecting tube 2.

After starting the motor 91, the turntable 9 can be rotated, so that the two connecting tubes 2 are alternately located under the sealing plate 6, so that the staff can quickly pick up the plastic bottles that have been inspected and place the plastic bottles to be inspected, thereby improving the inspection efficiency of the plastic bottles. The support rod 92 can increase the stability of the turntable 9 when it rotates. When the turntable 9 rotates, the battery 93 can supply power to the electrical components that rotate with the turntable 9.

[0022] When in use, after placing the large plastic bottle in the connecting tube 2, the electric telescopic rod 21 is started to drive the perforated plate 3 to move upward, so that the bottle mouth of the large plastic bottle is flush with the top of the connecting tube 2; then the hydraulic rod 7 is started to drive the sealing plate 6 to move downward, so that the bottom of the sealing plate 6 contacts the top of the connecting tube 2 and the bottle mouth of the large plastic bottle, thereby sealing the connecting tube 2 and the inside of the large plastic bottle; and after the vertical pipe 61 moves downward with the sealing plate 6, it is inserted into the large plastic bottle through the bottle mouth of the large plastic bottle, and then the No. 1 air pump 62 is started to transport the gas through the fixed pipe 63 After the gas reaches the vertical pipe 61, the vertical pipe 61 then transports the gas to the large plastic bottle, increasing the pressure inside the large plastic bottle; then the No. 1 air pump 62 is turned off, and the staff observes whether the value displayed on the No. 1 pressure gauge 10 will decrease. When the value on the No. 1 pressure gauge 10 decreases, it indicates that there are small cracks or holes in the large plastic bottle. When the value on the No. 1 pressure gauge 10 remains unchanged, it indicates that there are no defects such as small cracks or holes in the large plastic bottle; when the inspection of the large plastic bottle is completed, the sealing plate 6 is restored, and then the large plastic bottle is taken out from the connecting tube 2.
