Description

Technical Field

[0001] This utility model relates to the field of cosmetics processing, specifically a bottle inspection device for cosmetics processing. Background Technology

[0002] The airtightness test for cosmetic bottles is a device that simulates the pressure and environment that cosmetic bottles might experience in actual use to test their sealing performance. It is widely used by cosmetic manufacturers and quality inspection agencies, and can test cosmetic bottles of various materials and shapes, such as glass bottles, plastic bottles, and tubes. The testing methods are divided into negative pressure testing and positive pressure testing. The working principle of negative pressure testing is as follows: the cosmetic bottle to be tested is placed in a sealed chamber, and a vacuum is drawn into the sealed chamber to create a pressure difference between the inside and outside of the bottle. If the bottle leaks, bubbles will emerge; the sealing performance of the bottle is judged by observing the formation of bubbles. Sealing performance can also be determined by observing the expansion of the sample and the recovery of the sample's shape after the vacuum is released. The working principle of positive pressure testing is as follows: a certain pressure of gas, usually air or nitrogen, is injected into the cosmetic bottle to be tested through special tooling. After a certain pressure holding time, the change in gas pressure inside the sample is monitored in real time. If the sample has good sealing performance, the internal gas pressure will remain stable; if the sample leaks, the internal gas pressure will gradually decrease, thus determining whether the sample's sealing performance is qualified.

[0003] Existing bottle inspection devices in cosmetic processing use a retractable sealing head. When inspecting cosmetic bottles, the sealing head needs to be lowered to seal the bottle before a vacuum is drawn to check its airtightness. However, most current sealing heads in cosmetic bottle inspection devices are of a "fixed size or integrated connection" design. When inspecting cosmetic bottles with different opening sizes or different types (such as glass bottles or PE bottles), the entire sealing head assembly needs to be disassembled. Since the sealing head and the vent tube are fixed by 3-4 screws, disassembly requires unscrewing each screw with a screwdriver, removing the old sealing head, aligning it with the screw holes of the new sealing head, re-screwing, and calibrating the position to ensure the sealing head and vent tube are coaxial. This disassembly and assembly process is cumbersome and time-consuming, thus reducing the efficiency of disassembling and replacing the sealing head. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a bottle inspection device for cosmetic processing to solve the technical problem of inconvenience in quickly disassembling and replacing the sealing head.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottle inspection device for cosmetic processing, comprising a base and a lifting plate. A vent pipe is installed at the bottom of the lifting plate, and a fixing cylinder is fixed to the lower outer wall of the vent pipe. An installation sleeve is fitted onto the bottom end of the vent pipe, and a sealing head is installed at the bottom end of the installation sleeve. Multiple locking holes are formed on the upper outer wall of the installation sleeve. A limiting ring is threaded onto the outer wall of the fixing cylinder, and a clamping groove is formed inside the limiting ring. The outer wall of the limiting ring has anti-slip textures. Multiple springs are installed inside the fixing cylinder, and one end of each spring is connected to a locking post extending into the locking hole. A limiting rod extending outside the fixing cylinder is installed at one end of the locking post. A placement groove is formed at the top center of the base, and the placement groove is located directly below the sealing head.

[0006] By adopting the above technical solution, the placement slot opened at the top of the base is used to place the cosmetic bottle to be tested, ensuring that the bottle is located directly below the sealing head and avoiding misalignment of the seal.

[0007] Furthermore, a first hydraulic cylinder is installed on both sides of the base, and a lifting plate is installed at the output end of the first hydraulic cylinder via a piston rod.

[0008] By adopting the above technical solution, when the first hydraulic cylinder is working, the piston rod can be extended or retracted, which can then drive the lifting plate to move, and then drive the sealing head to move.

[0009] Furthermore, guide rods are installed on both sides of the top of the base, and a top plate is fixed to the top of the guide rods, and the guide rods pass through the lifting plate.

[0010] By adopting the above technical solution, the guide rod can ensure that the lifting plate moves in a straight line when moving up and down, avoiding misalignment between the sealing head and the bottle mouth due to shaking, and improving the sealing accuracy.

[0011] Furthermore, a vacuum pump is installed on the top of the top plate, and the air inlet of the vacuum pump is connected to a suction hose that penetrates the top plate, with the bottom end of the suction hose connected to the top end of the vent pipe.

[0012] By adopting the above technical solution, the vacuum pump provides power for negative pressure detection (by drawing air out of the bottle to form a vacuum), and the suction hose can move with the lifting plate to avoid damage to the pipeline.

[0013] Furthermore, the sealing head is made of fluororubber material, and both the sealing head and the mounting sleeve are detachably connected to the vent pipe.

[0014] By adopting the above technical solution, the fluororubber material of the sealing head has the characteristics of aging resistance and strong sealing performance. Moreover, both the sealing head and the mounting sleeve are detachable, which solves the problem of needing to replace the entire sealing assembly for different bottle mouth sizes and reduces the cost of replacement.

[0015] Furthermore, the inner wall of the mounting sleeve is provided with a sealing ring made of fluororubber material, and the inner wall of the sealing ring is in contact with the outer wall of the vent pipe.

[0016] By adopting the above technical solution, the fluororubber sealing ring fills the gap between the vent pipe and the mounting sleeve, preventing gas leakage from the connection and avoiding misjudgment of the test due to connection seal failure.

[0017] Furthermore, a pressure relief valve is installed on the mounting sleeve, and the bottom end of the pressure relief valve extends into the interior of the sealing head. A through hole is opened at the top of the fixed cylinder, and a dustproof mesh is installed inside the through hole.

[0018] By adopting the above technical solution, the pressure relief valve allows the device to slowly introduce air after the test is completed, balance the pressure difference inside and outside the bottle, and prevent airflow from impacting and contaminating the equipment.

[0019] Furthermore, the locking pin is adapted to the locking hole, the inner wall of the clamping groove and one end of the limiting rod are both set with an inclined surface, one end of the limiting rod is in contact with the inner wall of the clamping groove, and the spring is made of 304 stainless steel.

[0020] By adopting the above technical solution, it is ensured that the limit ring can smoothly push the locking pin when rotating, and the spring provides elasticity to make the locking pin embed into the locking hole, preventing the mounting sleeve from loosening; the 304 stainless steel material ensures rust resistance and long service life.

[0021] Furthermore, the base is also fixed with fixing plates on both sides of the top, and a second hydraulic cylinder is installed on one side of the fixing plate. The output end of the second hydraulic cylinder is fitted with a clamping plate through a piston rod, and a protective pad made of fluororubber is provided on one side of the clamping plate, and the clamping plate is arranged in an arc shape.

[0022] By adopting the above technical solution, the clamping plates are moved by the second hydraulic cylinder before the test, so that the two clamping plates clamp the bottle from both sides to prevent the bottle from shifting during the negative pressure test; while the fluororubber protective pads prevent the clamping plates from damaging the bottle body, and the arc design is adapted to the round bottle body to improve the clamping stability.

[0023] Furthermore, a pressure sensor is installed on one side of the vent pipe, and a control box is installed on the outer surface of the base. The control box is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the vacuum pump, the pressure sensor, and the pressure relief valve.

[0024] By adopting the above technical solution, the control box can set detection parameters (such as negative pressure value and pressure holding time), receive pressure sensor data to judge the sealing performance, and control the coordinated action of the first hydraulic cylinder, the second hydraulic cylinder, the vacuum pump, and the pressure relief valve, thereby reducing manual intervention and improving detection efficiency and accuracy.

[0025] In summary, the present invention has the following main advantages: 1. This utility model, by setting a limiting ring, a limiting rod, a spring, a locking pin, a locking hole, and a clamping groove, allows the operator to simply rotate the limiting ring to move it downwards when the sealing head needs to be disassembled for replacement. At this time, the limiting ring no longer squeezes the limiting rod, the spring contracts, and the locking pin moves out of the locking hole, releasing the limiting of the mounting sleeve. Thus, the mounting sleeve and the sealing head can be removed for replacement. This disassembly and replacement method is simple and convenient, requiring little time. The disassembly and replacement of the mounting sleeve and the sealing head can be achieved simply by rotating the limiting ring, thereby simplifying the disassembly and replacement steps and improving the efficiency of disassembly and replacement of the sealing head. 2. This utility model has a sealing ring to fill the gap between the vent pipe and the mounting sleeve, preventing gas leakage from the connection and avoiding misjudgment due to connection seal failure; and a pressure relief valve allows air to be slowly introduced into the device after the test is completed, balancing the pressure difference inside and outside the bottle and preventing airflow from impacting and contaminating the equipment.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1: A bottle inspection device for cosmetic processing, such as Figures 1-9 As shown, the device includes a base 1 and a lifting plate 3. A vent pipe 10 is installed at the bottom of the lifting plate 3, and a fixing cylinder 12 is fixed to the lower outer wall of the vent pipe 10. An installation sleeve 13 is fitted onto the bottom end of the vent pipe 10, and a sealing head 15 is installed at the bottom end of the installation sleeve 13. Multiple locking holes 24 are formed on the upper outer wall of the installation sleeve 13. A limit ring 20 is threadedly connected to the outer wall of the fixing cylinder 12. Both the outer wall of the fixing cylinder 12 and the inner wall of the limit ring 20 are threaded. A clamping groove 25 is formed inside the limit ring 20, and the outer wall of the limit ring 20 has anti-slip textures. Multiple springs 23 are installed inside the fixing cylinder 12, and one end of each spring 23 is connected to a locking post 22 extending into the locking hole 24. A limiting rod 21 extending outside the fixing cylinder 12 is installed at one end of the locking post 22. The locking post 22 is adapted to the locking hole 24. The inner wall of the clamping groove 25 and one end of the limiting rod 21 are both set with bevels. One end of the limiting rod 21 fits against the inner wall of the clamping groove 25. The spring 23 is made of 304 stainless steel to ensure that the locking post 22 can be smoothly pushed when the limiting ring 20 rotates. The spring 23 provides elastic force to make the locking post 22 embed into the locking hole 24 and prevent the mounting sleeve 13 from loosening. The 304 stainless steel material ensures rust resistance and long service life. The top of the mounting sleeve 13 is provided with positioning holes 28 around the perimeter. The bottom of the fixing cylinder 12 is provided with positioning posts 29 extending into the positioning holes 28 around the perimeter. The positioning posts 29 are adapted to the positioning holes 28. After the positioning posts 29 are inserted into the positioning holes 28, they can position the mounting sleeve 13 so that the locking post 22 can be aligned with the locking hole 24.

[0031] See Figure 3-9A placement groove 9 is provided at the top center of the base 1, and the placement groove 9 is located directly below the sealing head 15. The placement groove 9 on the top of the base 1 is used to place the cosmetic bottle to be tested, ensuring that the bottle is directly below the sealing head 15 to avoid misalignment of the seal. First hydraulic cylinders 2 are installed on both sides of the base 1, and lifting plates 3 are installed on the output end of the first hydraulic cylinders 2 through piston rods. When the first hydraulic cylinders 2 work, the piston rod can be extended or retracted, which can drive the lifting plate 3 to move, and then drive the sealing head 15 to move. Guide rods are installed on both sides of the top of the base 1. 7. The top of the guide rod 7 is fixed with a top plate 4, and the guide rod 7 passes through the lifting plate 3. The guide rod 7 can ensure that the lifting plate 3 moves in a straight line when it moves up and down, avoiding misalignment between the sealing head 15 and the bottle mouth due to shaking, thus improving the sealing accuracy. A vacuum pump 5 is installed on the top of the top plate 4, and the air inlet of the vacuum pump 5 is connected to a suction hose 6 that passes through the top plate 4. The bottom end of the suction hose 6 is connected to the top end of the vent pipe 10. The vacuum pump provides power for negative pressure detection (drawing air from the bottle to form a vacuum). The suction hose 6 can move with the lifting plate 3 to avoid damage to the pipeline by pulling.

[0032] See Figures 1-6 A pressure relief valve 26 is installed on the mounting sleeve 13, and the bottom end of the pressure relief valve 26 extends into the interior of the sealing head 15. A through hole 27 is opened at the top of the fixed cylinder 12, and a dustproof screen is installed inside the through hole 27. The setting of the pressure relief valve 26 allows air to be slowly introduced through the pressure relief valve 26 after the device is tested, so as to balance the pressure difference inside and outside the bottle and prevent the airflow from impacting and contaminating the equipment. Fixing plates 16 are also fixed on both sides of the top of the base 1, and a second hydraulic cylinder 17 is installed on one side of the fixing plate 16. A clamping plate 18 is installed on the output end of the second hydraulic cylinder 17 through the piston rod, and a protective pad 19 made of fluororubber material is provided on one side of the clamping plate 18. The clamping plate 18 is arc-shaped. Before the test, the clamping plate 18 is driven to move by the second hydraulic cylinder 17, so that the two clamping plates 18 clamp the bottle from both sides to prevent the bottle from being damaged during negative pressure testing. Displacement; while the fluororubber protective pad 19 prevents the clamp from damaging the bottle body, the arc design adapts to the round bottle body, improving clamping stability, a pressure sensor 11 is installed on one side of the vent pipe 10, and a control box 8 is installed on the outer surface of the base 1. The control box 8 is equipped with a touch screen, which usually has a dedicated "alarm" or "event" page; when the parameters are abnormal, an alarm message will pop up or be recorded, and the control box 8 is electrically connected to the first hydraulic cylinder 2, the second hydraulic cylinder 17, the vacuum pump 5, the pressure sensor 11 and the pressure relief valve 26 respectively. The detection parameters (such as negative pressure value, pressure holding time) can be set through the control box 8, and the data from the pressure sensor 11 can be received to judge the sealing performance. At the same time, the coordinated action of the first hydraulic cylinder 2, the second hydraulic cylinder 17, the vacuum pump 5 and the pressure relief valve 26 can be controlled to reduce manual intervention and improve detection efficiency and accuracy.

[0033] Example 2: Based on the above embodiment 1, in order to improve the performance of the sealing head 15, the sealing head 15 will be made of the following materials.

[0034] Specifically, the sealing head 15 is made of fluororubber material. Both the sealing head 15 and the mounting sleeve 13 are detachably connected to the vent tube 10. The fluororubber material of the sealing head 15 has the characteristics of aging resistance and strong sealing performance. Both the sealing head 15 and the mounting sleeve 13 are detachable, which solves the problem of replacing the entire sealing assembly for different bottle mouth sizes and reduces the cost of replacement.

[0035] Example 3: Based on the above embodiment 1, in order to improve the sealing between the mounting sleeve 13 and the vent pipe 10, the following structure will be provided.

[0036] Specifically, the inner wall of the mounting sleeve 13 is provided with a sealing ring 14 made of fluororubber material. The inner wall of the sealing ring 14 fits against the outer wall of the vent pipe 10. The fluororubber sealing ring 14 fills the gap between the vent pipe 10 and the mounting sleeve 13, preventing gas from leaking from the connection and avoiding misjudgment of the test due to connection seal failure.

[0037] The working principle of this utility model is as follows: First, before use, the operator turns on the power supply. Then, the operator places the cosmetic bottle to be tested into the placement slot 9 of the base 1. The control box 8 starts the second hydraulic cylinder 17, and the piston rod pushes the arc-shaped clamping plate 18 to move towards the bottle body until the fluororubber protective pad 19 fits against the bottle body and clamps the bottle body (to prevent the bottle body from shifting during testing). The control box 8 starts the first hydraulic cylinder 2, and the piston rod extends to push the lifting plate 3 down along the guide rod 7 (the guide rod 7 ensures that the lifting plate 3 moves in a straight line and avoids the sealing head 15 from shifting). The lifting plate 3 drives the vent pipe 10, the mounting sleeve 13 and the sealing head 15 down until the sealing head 15 completely fits against the bottle mouth to form a sealed space (the elasticity of the fluororubber sealing head 15 can fill the small burrs at the bottle mouth and enhance the sealing performance). Next, control box 8 starts vacuum pump 5, which draws air from the sealed space through suction hose 6 and vent pipe 10 to create a preset negative pressure value (e.g., -50kPa) inside the bottle. Pressure sensor 11 transmits the pressure data inside the bottle to control box 8 in real time. The system then shuts down the vacuum pump and enters the pressure holding stage (e.g., 3 seconds): if the pressure change during the pressure holding period is ≤2kPa, the seal is considered qualified; if the pressure rises rapidly (exceeding the threshold), the seal is considered unqualified, and control box 8 records the data and triggers an alarm. After the test is completed, the control box 8 opens the pressure relief valve 26 on the mounting sleeve 13, and the outside air slowly enters the bottle to balance the pressure difference between the inside and outside. The first hydraulic cylinder 2 drives the lifting plate 3 to rise and reset, the second hydraulic cylinder 17 drives the clamping plate 18 to loosen, and then the bottle is taken out. When the sealing head 15 needs to be replaced, the operator holds the anti-slip grooved limit ring 20 and rotates it counterclockwise (because the limit ring 20 is threadedly connected to the fixed cylinder 12). The limit ring 20 moves down along the outer wall of the fixed cylinder 12. The clamping groove 25 (sloping design) inside the limit ring 20 gradually disengages from the limit rod 21 as it moves down. After the spring 23 loses its clamping force, it retracts, which drives the locking pin 22 to be pulled out from the locking hole 24 of the mounting sleeve 13, releasing the locking of the mounting sleeve 13. Then, the mounting sleeve 13 and the sealing head 15 are pulled down directly to complete the disassembly. When installing the sealing head 15, the worker puts the installation sleeve 13 on the bottom of the vent pipe 10, aligns the positioning post 29 at the bottom of the fixing cylinder 12 with the positioning hole 28 at the top of the installation sleeve, and ensures that the locking post 22 and the locking hole 24 are coaxial. Then, the limiting ring 20 is rotated clockwise to move it up along the fixing cylinder 12, pressing against the inclined surface of the groove 25 to squeeze the limiting rod 21, pushing the locking post 22 to overcome the contraction force of the spring 23 and embed it into the locking hole 24, realizing the elastic locking of the installation sleeve 13. At this time, the fluororubber sealing ring 14 on the inner wall of the installation sleeve 13 is tightly fitted with the outer wall of the vent pipe 10, completing the installation of the sealing head 15.
