Description

Technical Field

[0001] This utility model relates to the field of air leakage detection technology, and in particular to an air leakage detection device for processing impermeable plastic bottles. Background Technology

[0002] PET plastic bottles are made of PET material, commonly known as polyester resin. Due to its excellent creep resistance, fatigue resistance, abrasion resistance, and dimensional stability, it exhibits low wear and high hardness, possessing the greatest toughness among thermoplastics. It also has good electrical insulation properties, is minimally affected by temperature, but has relatively poor corona resistance. It is non-toxic, weather-resistant, has good chemical stability, low water absorption, and is resistant to weak acids and organic solvents. Therefore, it is widely used in the liquid packaging field. Currently, after PET plastic bottle processing, there is a possibility of leakage in the finished bottles. In such cases, auxiliary devices are needed to detect leaks in the finished bottles.

[0003] Chinese utility model patent CN218156743U discloses an auxiliary device for processing PET plastic bottles, including a workbench. A PET plastic bottle fixing component is provided on the front side of the middle of the top surface of the workbench. An insertion / removal detection component is provided on the top surface of the workbench and above the PET plastic bottle fixing component. An air pump is provided on the rear side of the top surface of the workbench. An air supply hose is provided between the air pump and the insertion / removal detection component. The insertion / removal detection component, air pump, and air supply hose provided in the auxiliary device for processing PET plastic bottles can easily inject external gas into the PET plastic bottles and display the internal air pressure of the PET plastic bottles, thereby facilitating the detection of air leakage in the PET plastic bottles. Furthermore, the PET plastic bottle fixing component can fix the PET plastic bottles on the workbench surface, making the PET plastic bottles more stable on the workbench and facilitating the air pump and insertion / removal detection component to perform air filling detection on the PET plastic bottles.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: the device uses two opposing fixing rings to fix the plastic bottle. When using it, the operator needs to manually slide the two fixing rings while placing the plastic bottle between them. This makes it difficult for a single person to operate and results in a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a leak detection device for processing impermeable plastic bottles.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a leak detection device for processing anti-permeability plastic bottles, comprising a workbench, an air pump installed on the workbench, a plug-in detection component set on the workbench, and an air supply hose connected to the air pump. A fixed plate is installed on the upper surface of the workbench, and a placement groove is formed on the upper surface of the fixed plate. Two opposing sliding grooves are formed on the inner wall of the placement groove. A connecting column is slidably arranged in each of the two sliding grooves. A fixing ring is fixed to the end of each of the two connecting columns. Compression springs are connected to the side walls of the two connecting columns that are far apart from each other. The other ends of the two compression springs are fixed sequentially to the inner walls of the two sliding grooves that are far apart from each other. A driving component for driving the two fixing rings is provided on the fixed plate.

[0007] By employing the above technical solution, when workers need to detect leaks in plastic bottles, they activate the drive assembly, causing the two fixing rings to move simultaneously in a direction away from each other and ultimately stabilize under the action of the fixing device. At this point, the distance between the two fixing rings is greater than the diameter of the plastic bottle. Next, the worker places the processed PET plastic bottle between the two fixing rings and closes the fixing device, causing the two fixing rings to reset sequentially under the action of two compression springs, thus clamping the plastic bottle. Then, the worker activates the cylinder on the insertion / removal detection assembly, driving the lifting plate downwards. This causes the connecting plate and insertion tube on the insertion / removal detection assembly to move downwards with the lifting plate, allowing the insertion tube to be inserted into the PET plastic bottle. Finally, the worker turns on the air pump, which delivers gas into the PET plastic bottle through the air delivery hose. At this point, the worker only needs to observe the air pressure value displayed on the electronic pressure gauge on the insertion / removal detection assembly to determine whether the PET plastic bottle is leaking.

[0008] Furthermore, a rotating groove is provided on the side wall of the fixed disk, and the driving assembly includes an annular plate rotatably disposed in the rotating groove, two driving ropes with one end fixed to the side walls of two connecting columns that are far apart from each other, and a fixing device disposed on the fixed disk for limiting the position of the annular plate. The other ends of the two driving ropes extend into the rotating groove and are fixed to the inner wall of the annular plate.

[0009] By employing the above technical solution, when workers need to secure the plastic bottle, they must move the two securing rings away from each other. At this time, the worker rotates the annular plate, causing one end of each of the two drive ropes to rotate with the annular plate. This causes the two connecting posts to move away from each other sequentially under the action of the two drive ropes, thereby moving the two securing rings away from each other. Further, the worker activates the securing device to stabilize the annular plate. Then, the worker places the plastic bottle between the two securing rings and closes the securing device, causing the two securing rings to reset and clamp the plastic bottle, thus stabilizing it.

[0010] Furthermore, a drive groove is provided through the side wall of the annular plate, and a fixing hole is provided on the inner wall of the rotating groove. The fixing device includes a drive rod that is slidably disposed in the drive groove and a rubber sheet fixed on the side wall of the drive rod.

[0011] By adopting the above technical solution, when workers need to fix plastic bottles, they need to rotate the annular plate. When the fixing ring moves to its farthest end, the drive groove aligns with the fixing hole. At this time, workers only need to press the drive rod to move its end into the fixing hole, thereby limiting the drive rod's position on the annular plate and stabilizing the two fixing rings.

[0012] Furthermore, a return spring is fixed on the inner wall of the fixing hole away from the fixing rod.

[0013] By adopting the above technical solution, when the worker places the plastic bottle between the two fixing rings, the worker needs to reset the fixing rings. At this time, the worker only needs to press the drive rod again and quickly release the drive rod to continuously compress the return spring. When the worker quickly releases the drive rod, the drive rod quickly pops out under the action of the return spring, thereby reducing the difficulty for the worker to separate the drive rod from the fixing hole.

[0014] Furthermore, a sliding groove is provided on the side wall of the drive rod, and a limit block is fixed on the inner top wall of the drive groove, and the limit block is slidably connected to the sliding groove.

[0015] By adopting the above technical solution, when the operator slides the drive rod, the limiting block limits the drive rod, thereby reducing the probability of the drive rod separating from the drive groove and thus improving the user experience of the device.

[0016] Furthermore, the inner wall of the rotating groove is provided with a receiving groove for accommodating the drive rope.

[0017] By adopting the above technical solution, the receiving groove reduces the probability of the annular plate getting stuck, thereby improving the user experience for staff.

[0018] Furthermore, silicone sheets are provided on the sidewalls of the two fixing rings that are close to each other.

[0019] Furthermore, multiple driving rods are distributed in a circumferential array on the sidewall of the annular plate.

[0020] By adopting the above technical solution, when the staff needs to rotate the ring plate, the staff only needs to rotate the drive rod to make the ring plate rotate with the drive rod, thereby further reducing the difficulty for the staff to fix the plastic bottle.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. In this application, when an operator needs to perform a leak test on a plastic bottle, the operator activates the drive assembly, causing the two fixing rings to move simultaneously in a direction away from each other, and ultimately remain stable under the action of the fixing device. At this time, the distance between the two fixing rings is greater than the diameter of the plastic bottle. Further, the operator places the processed PET plastic bottle between the two fixing rings and closes the fixing device, causing the two fixing rings to reset sequentially under the action of two compression springs, thus clamping the plastic bottle. Subsequently, the operator activates the cylinder on the insertion / removal detection assembly, driving the lifting plate downwards, causing the connecting plate and insertion tube on the insertion / removal detection assembly to move downwards with the lifting plate, thereby inserting the insertion tube into the PET plastic bottle. Further, the operator activates the air pump, which delivers gas into the PET plastic bottle through the air delivery hose. At this point, the operator only needs to observe the air pressure value displayed on the electronic pressure gauge on the insertion / removal detection assembly to determine whether the PET plastic bottle is leaking.

[0023] 2. In this application, when the worker needs to fix the plastic bottle, the worker needs to move the two fixing rings in a direction away from each other. At this time, the worker needs to rotate the annular plate, so that one end of each of the two drive ropes follows the rotation of the annular plate, thereby causing the two connecting columns to move in a direction away from each other under the action of the two drive ropes, and thus causing the two fixing rings to move in a direction away from each other. Further, the worker needs to open the fixing device to keep the annular plate stable. Subsequently, the worker needs to place the plastic bottle between the two fixing rings and close the fixing device to reset the two fixing rings, thereby clamping the plastic bottle between the two fixing rings and keeping the plastic bottle stable.

[0024] 3. In this application, when the worker needs to fix the plastic bottle, the worker needs to rotate the annular plate. When the fixing ring moves to its farthest end, the drive groove is aligned with the fixing hole. At this time, the worker only needs to press the drive rod to move the end of the drive rod into the fixing hole, thereby limiting the drive rod to the annular plate and keeping the two fixing rings stable.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-5As shown in the embodiment of this application, a leak detection device for processing anti-permeability plastic bottles is disclosed, including a workbench 1, an air pump 11, an insertion / removal detection assembly 2, an air supply hose 21, a fixed plate 3, a connecting column 4, a fixing ring 41, a compression spring 5, a drive assembly 6, a reset spring 8, a limit block 82, a silicone sheet 84, and a drive rod 9. The air pump 11 is installed on the workbench 1, and the insertion / removal detection assembly 2 is set on the workbench 1. The insertion / removal detection assembly 2 includes columns set on the left and right sides of the top surface of the workbench 1. A top plate is set on the top of the column, and a cylinder is set on the top of the top plate. A lifting plate is sleeved on the outer wall of the column, and a connecting plate is set between the lifting plates. An insertion tube is sleeved in the middle of the connecting plate. A solenoid valve is installed on the insertion tube above the connecting plate, and an electronic pressure gauge is installed on the insertion tube to the west of the connecting plate. The air supply hose 21 is connected to the air pump 11, and the other end of the air supply hose 21 is connected to the insertion tube.

[0033] The upper surface of the fixed plate 3 has a placement groove 31, and the inner wall of the placement groove 31 has two opposing sliding grooves 32. The connecting post 4 is a round rod structure, and there are two connecting posts 4, which are slidably disposed in the two sliding grooves 32. The fixing ring 41 is a circular annular plate 61 structure, and there are two fixing rings 41, which are fixed to the ends of the two connecting posts 4 in sequence. There are two compression springs 5, and one end of the two compression springs 5 ​​is connected to the side walls of the two connecting posts 4 that are far apart from each other. The other ends of the two compression springs 5 ​​are fixed to the inner walls of the two sliding grooves 32 that are far apart from each other.

[0034] A rotating groove 51 is provided on the side wall of the fixed disk 3. The driving assembly 6 is mounted on the fixed disk 3 and is used to drive the two fixed rings 41. The driving assembly 6 includes an annular plate 61, driving ropes 62, and a fixing device 7. The annular plate 61 is a circular annular plate structure and is rotatably mounted in the rotating groove 51. There are two driving ropes 62, one end of which is fixed to the side walls of the two connecting columns 4 that are far apart from each other. The other ends of the two driving ropes 62 extend into the rotating groove 51 and are fixed to the inner wall of the annular plate 61.

[0035] When the worker needs to secure the plastic bottle, they must move the two fixing rings 41 in a direction away from each other. At this time, the worker needs to rotate the annular plate 61, causing one end of each of the two drive ropes 62 to rotate with the annular plate 61. This causes the two connecting posts 4 to move in a direction away from each other under the action of the two drive ropes 62, thereby moving the two fixing rings 41 in the same direction. Further, the worker needs to activate the fixing device 7 to stabilize the annular plate 61. Then, the worker needs to place the plastic bottle between the two fixing rings 41 and close the fixing device 7 to reset the two fixing rings 41, thus clamping the plastic bottle and stabilizing it.

[0036] A drive groove 63 is formed through the side wall of the annular plate 61, and a fixing hole 64 is formed on the inner wall of the rotating groove 51. A fixing device 7 is mounted on the fixing plate 3 to limit the position of the annular plate 61. The fixing device 7 includes a drive rod 71 and a rubber sheet 72. The drive rod 71 is a round rod structure and is slidably disposed in the drive groove 63. The rubber sheet 72 is a block structure and is fixed to the side wall of the drive rod 71.

[0037] When workers need to secure the plastic bottle, they need to rotate the annular plate 61. When the fixing ring 41 moves to its farthest point, the drive groove 63 aligns with the fixing hole 64. At this time, workers only need to press the drive rod 71 to move the end of the drive rod 71 into the fixing hole 64, thereby limiting the annular plate 61 and stabilizing the two fixing rings 41.

[0038] One end of the return spring 8 is fixed to the inner wall of the fixing hole 64 away from the fixing rod, while the other end of the return spring 8 remains suspended. When the worker places the plastic bottle between the two fixing rings 41, the worker needs to reset the fixing rings 41. At this time, the worker only needs to press the drive rod 71 again and quickly release the drive rod 71 to continuously compress the return spring 8. When the worker quickly releases the drive rod 71, the drive rod 71 quickly pops out under the action of the return spring 8, thereby reducing the difficulty for the worker to separate the drive rod 71 from the fixing hole 64.

[0039] A sliding groove 81 is provided on the side wall of the drive rod 71. The limiting block 82 is a block structure and is fixed to the inner top wall of the drive groove 63, and is slidably connected to the sliding groove 81. When the operator slides the drive rod 71, the limiting block 82 limits the drive rod 71, thereby reducing the probability of the drive rod 71 separating from the drive groove 63, and thus improving the user experience of the device.

[0040] In order to reduce the probability of the ring plate 61 getting stuck and thus improve the user experience of the staff, a receiving groove 83 for accommodating the drive rope 62 is provided on the inner wall of the rotating groove 51.

[0041] The silicone sheet 84 is a sheet-like structure, and two silicone sheets 84 are arranged sequentially on the sidewalls of the two fixing rings 41 that are close to each other. The driving rod 9 is a circular rod-like structure, and multiple driving rods 9 are arranged in a circumferential array on the sidewall of the annular plate 61.

[0042] When the staff needs to rotate the ring plate 61, they only need to rotate the drive rod 9 to make the ring plate 61 rotate with the drive rod 9, which further reduces the difficulty for the staff to fix the plastic bottle.

[0043] The operating principle of the leak detection device for processing impermeable plastic bottles in this embodiment is as follows: When the operator needs to detect leaks in the plastic bottle, the operator activates the drive assembly 6, which causes the two fixing rings 41 to move simultaneously in a direction away from each other under the action of the drive assembly 6, and finally remain stable under the action of the fixing device 7. At this time, the distance between the two fixing rings 41 is greater than the diameter of the plastic bottle. Further, the operator places the processed PET plastic bottle between the two fixing rings 41 and closes the fixing device 7, which causes the two fixing rings 41 to reset sequentially under the action of the two compression springs 5, thereby clamping the plastic bottle. Subsequently, the operator activates the cylinder on the insertion / removal detection assembly 2, driving the lifting plate downwards, which causes the connecting plate and the insertion tube on the insertion / removal detection assembly 2 to move downwards with the lifting plate, thereby inserting the insertion tube into the PET plastic bottle. Further, the operator activates the air pump 11, which delivers gas into the PET plastic bottle through the air delivery hose 21. At this point, staff only need to observe the air pressure value displayed on the electronic pressure gauge on the plug-in detection component 2 to determine whether the PET plastic bottle is leaking.

[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
