[0002] PE bottles are plastic containers made of polyethylene. They are non-toxic, chemically resistant, and low-temperature resistant, and are widely used in food packaging, daily chemical products, and other fields. The airtightness of PE bottles is one of the most important indicators that must be tested.

[0003] Existing patent publication number CN204503612U, entitled "A PE Bottle Sealing Test and Disinfection Device," proposes a new invention comprising a detection device, an infrared heating device, and an ultraviolet sterilization device arranged sequentially along a conveyor belt. The detection device includes a pushing and blowing device and a pushing and sensing device positioned on both sides of the conveyor belt.

This device offers high detection efficiency and integrates the disinfection process, significantly reducing the overall process time and saving costs.

[0004] However, the sealing test device for PE bottle production disclosed in the above patent does not limit the PE bottle during use. During the sealing test, the PE bottle is prone to tilting or lateral displacement, which affects the test results. Therefore, it is necessary to propose a sealing tester for PE bottle production to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing performance tester for PE bottle production, comprising a support base, a stepper motor fixedly installed inside the support base, a rotating disk fixedly connected to the output end of the stepper motor, four limiting grooves evenly arranged in a ring on the outer circumference of the rotating disk, four conveyor frames fixedly installed on the side of the support base, the four conveyor frames being evenly arranged in a ring around the central axis of the rotating disk, a conveyor belt rotatably installed inside the conveyor frame, PE bottles being conveyed on the conveyor belt, side plates fixedly installed at both ends of the top of the conveyor frame, the conveyor belt extending below the rotating disk, a gap between the lower surface of the rotating disk and the upper surface of the conveyor frame, a connecting block fixedly installed between two adjacent conveyor frames, an arc plate fixedly installed on the top of the connecting block, the heights of the connecting block, the conveyor belt, and the upper surface of the conveyor frame all being at the same horizontal level, the outer wall of the rotating disk and the inner wall of the arc plate being movably fitted together, and the outer wall of the rotating disk and the ends of the side plates being movably fitted together;

[0007] A detection assembly is installed between the two conveyor frames located in the front-to-back direction.

[0008] Preferably, the two conveyor frames located in the front-to-back direction are used to transport PE bottles to be tested, and the two conveyor frames located in the left-to-right direction are used to transport PE bottles that have completed testing.

[0009] Preferably, the detection component includes four uprights, which are respectively fixedly mounted on the top of four side plates located in the front-rear direction. A top plate is fixedly connected between the upper ends of the four uprights. A hydraulic cylinder is fixedly mounted in the middle of the top of the top plate. A lifting plate is fixedly connected to the telescopic end of the hydraulic cylinder. Air blowers are fixedly mounted at both ends of the bottom of the lifting plate. A sealing plate is fixedly mounted at the bottom of the air blowers. An air pipe is fixedly mounted at the bottom of the sealing plate. A detection tube is fixedly mounted on the side of the sealing plate. A pressure gauge is fixedly mounted at the end of the detection tube. A flow divider is provided inside the sealing plate. The air pipe, the detection tube, and the flow divider are interconnected.

[0010] Preferably, in the initial state, the four limiting grooves correspond to the four conveyor belts respectively. The end of the limiting groove away from the opening is a semi-circular structure, which is adapted to the PE bottle, and the central axis of the semi-circular structure and the central axis of the air pipe are on the same straight line.

[0013] Preferably, the PE bottle and the side panel are movably fitted together.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In the process of using this utility model, multiple PE bottles to be tested are placed on the conveyor belts of two conveyor frames located in the front-to-back direction. After the two conveyor belts are running, the two PE bottles to be tested are driven into the interior of two limiting grooves, which quickly completes the limiting of the PE bottles. At this time, the hydraulic cylinder is activated, which drives the lifting plate, air blower, sealing plate, air pipe, detection tube and pressure gauge to move downward. The two air pipes are inserted into the interior of the two PE bottles respectively. The sealing plate presses down the top of the PE bottle. With the limiting assistance of the limiting grooves, the PE bottles can be prevented from tilting or shifting during the testing process. This solves the problem that existing PE bottle sealing test devices do not limit the PE bottles during use, and the PE bottles are prone to tilting or shifting during the sealing test, which affects the test results.

[0016] 2. After the sealing plate seals the top of the PE bottle, the air blower pumps air into the inside of the distribution chamber and observes the pressure gauge reading. If the reading remains unchanged within the specified time, the PE bottle has good sealing performance. If the reading changes within the specified time, the PE bottle has unqualified sealing performance. Since this utility model can test two PE bottles simultaneously at a time, it improves the efficiency of the device's testing.

[0017] 3. After the test is completed, start the hydraulic cylinder to reset the air pipe, then start the stepper motor to drive the rotating plate to rotate 90 degrees, which in turn moves the two PE bottles that have been tested to the conveyor belts of the two conveyor frames located in the left and right directions. After running the two conveyor belts, the two PE bottles that have been tested are conveyed and unloaded, improving the convenience of loading and unloading of the device.

[0026] Furthermore, the two conveyor frames 4 located in the front-to-back direction are used to transport the PE bottles 7 to be tested, and the two conveyor frames 4 located in the left-to-right direction are used to transport the PE bottles 7 that have completed the testing.

[0027] Furthermore, a detection assembly is provided between the two conveyor frames 4 located in the front-rear direction. The detection assembly includes four uprights 9. The four uprights 9 are respectively fixedly installed on the top of the four side plates 6 located in the front-rear direction. A top plate 10 is fixedly connected between the upper ends of the four uprights 9. A hydraulic cylinder 11 is fixedly installed in the middle of the top of the top plate 10. A lifting plate 12 is fixedly connected to the telescopic end of the hydraulic cylinder 11. The lifting plate 12 is located between the four uprights 9, and the lifting plate 12 and the uprights 9 are movably fitted together. Air blowers 13 are fixedly installed at both ends of the bottom of the lifting plate 12. A sealing plate 14 is fixedly installed at the bottom of the air blower 13. An air pipe 15 is fixedly installed at the bottom of the sealing plate 14. A detection tube 16 is fixedly installed on the side of the sealing plate 14. A pressure gauge 17 is fixedly installed at the end of the detection tube 16. A diversion chamber is provided inside the sealing plate 14.

After the two conveyor belts 5 are running, the two PE bottles that have completed the test are conveyed and unloaded, improving the convenience of loading and unloading of the device.

[0032] By repeating the above steps, the PE bottle 7 can be continuously tested.
