Description

Technical Field

[0001] This utility model relates to the technical field of sealing performance testing, and more specifically, to a bottle cap sealing performance testing device. Background Technology

[0002] Plastic bottle caps are produced through injection molding. During the injection molding process, uneven injection can lead to substandard sealing of the bottle caps. This is mainly caused by poor injection molding, resulting in uneven thickness of different parts of the bottle cap, deformation of the bottle cap after injection molding, or insufficient injection molding, leading to substandard appearance.

[0003] Manual inspection is insufficient to detect defective bottle caps, and manual inspection is both labor-intensive and inefficient. Using water or other media can lead to on-site contamination. Therefore, a more efficient batch bottle cap sealing inspection device should be designed. Utility Model Content

[0004] The purpose of this invention is to provide a bottle cap sealing performance testing device that can efficiently and automatically test the sealing performance of bottle caps.

[0005] This utility model is achieved through the following technical solution: The bottle cap sealing performance testing device of this utility model includes a feeding track, a discharging track, and a testing device disposed between the feeding track and the discharging track; the testing device includes a horizontally arranged base plate, a dial rotatably disposed on the base plate, multiple slots opened on the edge of the dial, multiple pressure devices opened on the base plate, and multiple pressing devices disposed above the base plate, with one pressure device disposed directly below one pressing device.

[0006] Furthermore, the pressurizing device includes an air guide pipe located below the base plate, an air inlet pipe connected to the lower end of the air guide pipe, an air compressor connected to the air inlet pipe, and a barometer connected to the side of the air guide pipe; the upper end of the air guide pipe passes through the base plate.

[0007] Furthermore, a first three-way valve is provided at the end of the air duct away from the base plate; the air inlet pipe is connected to the first three-way valve, and the first three-way valve is also connected to an exhaust pipe.

[0008] Furthermore, the air guide tube is connected to the barometer via a connecting pipe, and the connecting pipe is equipped with a second three-way valve, which is connected to a vent pipe.

[0009] Furthermore, both the first three-way valve and the second three-way valve are automatic valves.

[0010] Furthermore, the pressing device includes a vertically positioned cylinder facing downwards, and a pressing block located at the end of the telescopic rod of the cylinder; the lower side of the pressing block abuts against the upper surface of the bottle cap.

[0011] Furthermore, the discharge track is provided with a waste pipe and an air blowing pipe; the waste pipe and the air blowing pipe are respectively located on opposite sides of the discharge track; the air blowing pipe is connected to a compressed air source; the air blowing pipe is oriented towards the waste pipe, and both the waste pipe and the air blowing pipe are perpendicular to the discharge track.

[0012] The technical solution of this utility model has at least the following advantages and beneficial effects: In use, the bottle cap sealing performance testing equipment of this utility model transports bottle caps to the testing device via a feeding track. The bottle caps move to the base plate, and as the dial rotates, the bottle caps are inserted into the slots on the edge of the dial. The dial then moves to the pressurizing device and stops rotating. At this point, the pressing device applies pressure to the bottle caps, making them adhere tightly to the base plate. Air is then injected into the bottle caps using the pressurizing device and the pressure is maintained for a period of time. Whether there is a significant change in air pressure is detected, which determines the sealing performance of the bottle caps. Finally, the bottle caps are discharged through the discharge track.

Detailed Implementation

[0017] Example

[0018] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 3As shown, the bottle cap sealing test device of this embodiment includes a feeding track 11, a discharging track 12, and a test device 20 disposed between the feeding track 11 and the discharging track 12; the test device 20 includes a horizontally arranged base plate 21, a dial 22 rotatably disposed on the base plate 21, a plurality of slots 23 opened on the edge of the dial 22, a plurality of pressure devices 24 opened on the base plate 21, and a plurality of pressing devices 25 disposed above the base plate 21, with one pressure device 24 disposed directly below one pressing device 25. Specifically, during use, the bottle cap 30 is transported to the testing device 20 via the feeding track 11. The bottle cap 30 moves onto the base plate 21, and as the dial 22 rotates, the bottle cap 30 is inserted into the slot 23 on the edge of the dial 22. It then moves to the pressurizing device 24 and stops rotating. At this time, the pressing device 25 applies pressure to the bottle cap 30, making the bottle cap 30 stick tightly to the base plate 21. Then, the pressurizing device 24 injects air into the bottle cap 30 and holds the pressure for a period of time, detecting whether there is a significant change in air pressure. This can be used to determine the sealing performance of the bottle cap 30. Finally, the bottle cap 30 is discharged through the discharge track 12. This method can quickly and efficiently perform sealing performance testing on multiple bottle caps 30 at once, effectively improving the efficiency of bottle cap sealing performance testing.

[0019] The pressurizing device 24 in this embodiment includes an air guide pipe 241 located below the base plate 21, an air inlet pipe 242 connected to the lower end of the air guide pipe 241, an air compressor connected to the air inlet pipe 242, and a barometer 245 connected to the side of the air guide pipe 241; the upper end of the air guide pipe 241 passes through the base plate 21. Specifically, air is pressurized into the bottle cap 30 by the air compressor, the air inlet pipe 242, and the air guide pipe 241 to form a high pressure within a certain range (approximately 0.3 MPa). Then, the barometer 245 detects the change in air pressure over a certain period of time, and the change in air pressure is used to determine whether there is any leakage, i.e., whether the sealing is good.

[0020] In this embodiment, the end of the air guide pipe 241 furthest from the base plate 21 is equipped with a first three-way valve 243; the air inlet pipe 242 is connected to the first three-way valve 243, and the first three-way valve 243 is also connected to the exhaust pipe 244. Specifically, when air inflation and pressurization are required, the first three-way valve 243 connects the air inlet pipe 242 and the air guide pipe 241 to start inflation. After inflation is completed, the first three-way valve 243 activates, connecting the air inlet pipe 242 and the exhaust pipe 244. At this time, the air guide pipe 241 is closed, and the gas generated by the air compressor can be directly discharged through the exhaust pipe 244. This eliminates the need for frequent opening and closing of the air valve and for starting and stopping the air compressor, thus maintaining continuous and efficient system operation.

[0021] In this embodiment, the gas guide tube 241 and the barometer 245 are connected by a connecting tube 246. The connecting tube 246 is equipped with a second three-way valve 247, which is connected to a vent tube 248. Specifically, the second three-way valve 247 can quickly release the gas in the bottle cap 30, preventing the bottle cap 30 from being blown away by the high-pressure gas inside when the pressing device 25 is not pressing the bottle cap 30.

[0022] In this embodiment, both the first three-way valve 243 and the second three-way valve 247 are automatic valves.

[0023] The pressing device 25 in this embodiment includes a vertically positioned, downward-facing cylinder 251 and a pressing block 252 located at the end of the telescopic rod of the cylinder 251; the lower side of the pressing block 252 abuts against the upper surface of the bottle cap 30. Specifically, by pushing the pressing block 252 onto the bottle cap 30 through the cylinder 251, the bottle cap 30 can be made to fit tightly against the base plate 21.

[0024] In this embodiment, the discharge track 12 is equipped with a waste pipe and an air blowing pipe; the waste pipe and the air blowing pipe are respectively located on opposite sides of the discharge track 12; the air blowing pipe is connected to a compressed air source; the air blowing pipe is oriented towards the waste pipe, and both the waste pipe and the air blowing pipe are perpendicular to the discharge track 12. Specifically, when a bottle cap 30 is detected to have a poor seal, when the bottle cap 30 moves between the air blowing pipe and the waste pipe on the discharge track 12, the air source discharges compressed air, which blows the bottle cap 30 into the waste pipe through the air blowing pipe for discharge.

[0025] In summary, the bottle cap sealing performance testing equipment of this embodiment transports the bottle cap 30 to the testing device 20 via the feeding track 11. The bottle cap 30 moves onto the base plate 21, and as the dial 22 rotates, the bottle cap 30 is inserted into the slot 23 on the edge of the dial 22. It then moves to the pressurizing device 24 and stops rotating. At this time, the pressing device 25 applies pressure to the bottle cap 30, making the bottle cap 30 stick tightly to the base plate 21. Then, the pressurizing device 24 injects air into the bottle cap 30 and holds the pressure for a period of time, detecting whether there is a significant change in air pressure. This allows the sealing performance of the bottle cap 30 to be determined. Finally, the bottle cap 30 is discharged through the discharge track 12. This method can quickly and efficiently perform sealing performance testing on multiple bottle caps 30 at once, effectively improving the efficiency of bottle cap sealing performance testing.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
