Description

Technical Field

[0001] The invention relates to the technical field of bottle air tightness detection, in particular to an air tightness detection device and a detection method for a screw-mouth perfume bottle. Background Art

[0002] Air tightness testing of perfume bottles is an important step in ensuring the quality of perfume bottles and the preservation effect of perfume. Conventional testing methods include water pressure testing, air pressure testing and ammonia testing.

[0003] Most of these methods require adding additional media to the perfume bottles, which requires additional operations of discharging and adding media, or they need to be docked with the detection equipment one by one. Each detection requires manual or mechanical precise docking of the perfume bottles with the detection equipment. This process includes positioning, installation, connection and other steps, which will take a certain amount of time. Especially in large-scale production, a large number of perfume bottles need to be tested. Docking one by one will seriously affect the detection speed and reduce the overall production efficiency.

[0004] When additional discharge media and installation media are added, no matter water, gas (such as compressed air, helium, etc.) or other special media are selected, they need to be purchased, which undoubtedly increases the direct cost of detection. If a large amount of media or expensive special media is required, the cost will be higher. In order to store, transport and discharge these media, corresponding equipment is required, such as storage tanks, pipelines, pumps, etc., which increases the purchase and maintenance costs of the equipment. At the same time, the operation of adding and discharging media requires additional manpower input, which increases labor costs. Before the test, it takes time to prepare enough media and install them in the detection system. After the test is completed, the discharged media needs to be processed and cleaned. This series of operations will increase the overall detection time and reduce the detection efficiency. Summary of the invention

[0013] Preferably, the lower sealing leather pad is composed of an outer bendable ring on the outer side and an inner fixed ring on the inner side.

[0014] Preferably, a placement groove corresponding to the perfume bottle is provided on the perfume bottle placement rack, a drainage groove is provided at the bottom of the inner wall of the placement groove, and a plurality of auxiliary fixing strips are provided on the circumferential side surface of the inner wall of the placement groove.

[0015] A method for detecting air tightness of a screw-mouth perfume bottle, comprising the following steps: The first step: install the structure consisting of the perfume bottle placement rack and the guide wheel on the assembly frame. The structure consisting of the perfume bottle placement rack and the guide wheel is placed on the horizontal assembly beam and the assembly frame. The horizontal assembly beam and the assembly frame descend to reach the color water detection box. The lower sealing leather pad, the upper sealing leather pad and the rectangular lifting plate seal the color water detection box. The air compressor is used to pressurize the corrugated exhaust pipe. After a vacuum space is formed in the color water detection box, the color water will enter the screw-mouth perfume bottle with a poor seal.

[0016] Step 2: After a period of vacuum negative pressure, the piston rod of the electric push rod drives the horizontal assembly beam and the assembly frame to rise, and the perfume bottles on the perfume bottle rack are rinsed by spraying water through the spray belt. After the rinsing is completed, the perfume bottles that have been tested are removed.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The perfume bottle with the bottle cap installed is placed in the placement groove. The structure composed of the perfume bottle placement rack and the guide wheel is installed on the assembly frame. The horizontal assembly beam and the assembly frame are lowered to reach the color water detection box. The structure composed of the lower sealing leather pad and the upper sealing leather pad corresponds to the gap between the color water detection box and the rectangular lifting plate. The air compressor is used to pressurize the corrugated exhaust pipe to form a vacuum space in the color water detection box. The color water will enter the screw-mouth perfume bottle. The screw-mouth perfume bottle contains the color of the color water. The lifting structure drives the sealing structure to descend, which can fit closely with the color water detection box to form a good sealing environment and effectively avoid interference from the outside air. In this way, when the color water detection box is vacuumed, the sealing state of the perfume bottle in actual use can be accurately simulated to ensure that the test results are true and reliable. After the vacuuming is completed, the perfume bottle is tested The penetration of inner color water can accurately judge the sealing performance of the bottle body and improve the accuracy of detection. The whole detection process has a high degree of automation. The coordinated work of the lifting structure and the sealing structure can quickly complete the sealing operation of the box body. The vacuuming process is also relatively rapid, which greatly shortens the time for detecting the sealing effects of multiple bottles. This method can realize batch detection. Through the reasonable design of the box body and the detection equipment, the sealing effects of multiple bottles can be detected at the same time, which improves the detection efficiency on the production line and meets the needs of large-scale production. This detection method does not require destructive operation on the bottle body and will not cause damage to the bottle body, ensuring the integrity and reusability of the bottle body after detection. For some high-value or fragile bottles, non-destructive testing is particularly important, which can not only ensure product quality but also reduce production costs.

[0018] 2. After the colored water in the color water detection box leaves the structure composed of the horizontal assembly beam and the assembly frame, the perfume bottles on the perfume bottle rack are rinsed by spraying water through the spray belt. After the rinsing is completed, the color water detection and rinsing process is relatively simple and fast, and a large number of perfume bottles can be detected and processed in a short time. Through this rapid screening method, unqualified perfume bottles can be found in time and removed from the production line to avoid further processing of unqualified products in subsequent processes, thereby improving the efficiency of the entire production process. Perfume bottles, as cosmetic packaging containers that are in direct contact with the human body, must meet strict hygiene standards. The rinsing process after the color water detection can effectively remove impurities and microorganisms in the bottle, ensuring that the perfume bottles meet hygiene requirements and guaranteeing the safety of consumers.

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 14 The present invention provides a technical solution: a screw-mouth perfume bottle air tightness detection device, comprising a color water detection box 1 and a support base frame 2 arranged at the bottom of the color water detection box 1. The color water detection box 1 is a box for placing color water, and the color water is located in the color water detection box 1. The support base frame 2 is used to lift and raise the color water detection box 1. Color water generally refers to colored water. In the sealing detection of products such as perfume bottles, colored water is widely used. The perfume bottle is immersed in the colored water, and whether there is a leak is determined by observing whether there is a color change on the surface of the bottle body. If the bottle body leaks, the colored water will enter the bottle, making the liquid in the bottle colored, so as to intuitively detect the sealing performance of the product; To assist in the installation of the bottom components of the color water detection box 1, an assembly top frame 3 is fixedly installed on the top of the color water detection box 1. The assembly top frame 3 is composed of multiple transverse beams and a longitudinal beam to assist the installation of the electric push rod 4 on the assembly top frame 3. An electric push rod 4 is fixedly installed on the top of the assembly top frame 3. The piston rod of the electric push rod 4 drives the corresponding structure to rise and fall to assist in the lifting and falling of the structure for placing the perfume bottle. A transverse assembly beam 5 is fixedly installed on the bottom end of the piston rod of the electric push rod 4. An assembly frame 6 is fixed at the bottom of the transverse assembly beam 5. The assembly frame 6 is a hollow frame to ensure the contact area between the color water and the perfume bottle to ensure the contact between the color water and the cap of the perfume bottle and the connection position of the perfume bottle. Multiple horizontally mounted components are provided on the assembly frame 6. A U-shaped guide rail 7 is provided, and the U-shaped guide rail 7 is a rail corresponding to the guide wheel 9 under the perfume bottle placement rack 8, so as to guide the movement of the structure composed of the perfume bottle placement rack 8 and the guide wheel 9, so as to ensure the movement stability and convenience of the structure composed of the perfume bottle placement rack 8 and the guide wheel 9. A perfume bottle placement rack 8 is arranged above the U-shaped guide rail 7, and a groove corresponding to the perfume bottle is opened on the perfume bottle placement rack 8. A guide wheel 9 slidably connected to the U-shaped guide rail 7 is provided at the bottom of the perfume bottle placement rack 8. The guide wheel 9 is slidably connected to the U-shaped guide rail 7 to guide the movement of the guide wheel 9. The design of the guide wheel 9 needs to consider the adaptability to the U-shaped guide rail 7 to ensure that the guide wheel 9 can move smoothly on the U-shaped guide rail 7. The two parallel track surfaces of the U-shaped guide rail 7 provide precise guidance for the guide wheel 9, which limits the guide wheel 9 to move only along a specific direction in the track. When the placement rack 8 needs to move, the guide wheel 9 will roll along a predetermined path under the guidance of the U-shaped guide rail 7, so as to realize the placement rack 8. Directional movement to avoid random deviation, the piston rod of the electric push rod 4 is fixedly installed with an annular sealing buckle 10, the annular sealing buckle 10 seals the connection position between the rectangular lifting plate 11 and the piston rod of the electric push rod 4, ensuring that a relatively sealed structure is formed in the color water detection box 1, and a rectangular lifting plate 11 is fixedly installed outside the annular sealing buckle 10. The rectangular lifting plate 11 is engaged with the upper surface of the color water detection box 1. The rectangular lifting plate 11 and the annular sealing buckle 10 form a sealed cavity, and a spraying belt 12 is provided at the bottom of the rectangular lifting plate 11. The spraying belt 12 is controlled by a separate pipeline, and clean water is sprayed out through the spraying belt 12. To rinse the perfume bottle stained with colored water, a corrugated air extraction pipe 13 is fixedly installed through the rectangular lifting plate 11. The corrugated air extraction pipe 13 is a deformable pipe to adapt to the operation of the piston rod lifting of the electric push rod 4. The corrugated air extraction pipe 13 is fixedly installed on the assembly top frame 3 through a fixed clamp ring 14. The corrugated air extraction pipe 13 is a pipe with a special structure, which is usually used for extracting gas. Its pipe wall is corrugated, which is the main difference from ordinary straight pipes. This corrugated structure makes the pipe have better flexibility and bendability, and can adapt to different installation environments and space requirements. Common materials include plastic, rubber, metal, etc.Corrugated exhaust pipes of different materials have different performance characteristics, such as plastic corrugated exhaust pipes are light and corrosion-resistant; rubber corrugated exhaust pipes are flexible and have good sealing performance; metal corrugated exhaust pipes are strong and resistant to high temperatures, etc. By connecting a vacuum pump or other exhaust equipment, a negative pressure is formed inside the pipe, so that the external gas is sucked into the pipe under the action of the pressure difference, and then transported to the designated location. It can be easily bent and deformed, adapt to complex installation paths and spatial layouts, and reduce the difficulty and cost of the pipeline installation process. According to different material selections, it can resist the erosion of various chemical substances and is suitable for different The working medium, the corrugated structure helps to improve the sealing performance of the pipeline, reduce the leakage of gas or liquid, and ensure the effect of air extraction. The corrugated exhaust pipe 13 is connected to the spray belt 12 to realize the extraction of gas in the structure composed of the color water detection box 1 and the rectangular lifting plate 11. The corrugated exhaust pipe 13 is connected to the air compressor. The air compressor continuously extracts the gas in the closed space through mechanical or physical methods, so that the number of gas molecules in the space is reduced, thereby reducing the air pressure and reaching a vacuum state. In the process of extracting gas, the vacuum machine needs to maintain good sealing to prevent external gas from entering the evacuated space and ensure the stability of the vacuum degree.

[0036] A drain pipe 15 is fixedly installed at the bottom of the color water detection box 1, and a regulating valve 16 is fixedly installed on the drain pipe 15. The drain pipe 15 and the regulating valve 16 form a structure for controlling the discharge of the color water in the color water detection box 1. The sealing or discharge of the drain pipe 15 is controlled by the regulating valve 16. The valve core inside the regulating valve 16 is closely matched with the valve seat. When sealing is required, the valve core is driven to move by the actuator so that the valve core and the valve seat are completely fitted, thereby cutting off the channel of the color water in the drain pipe 15 and preventing the color water from continuing to be discharged. When the control system sends a signal to discharge the color water, the actuator of the regulating valve 16 will drive the valve core to move in the valve body according to the size and direction of the signal, thereby changing the flow cross-sectional area between the valve core and the valve seat. The flow cross-sectional area increases, the flow of the color water increases, and the discharge function is realized.

[0037] A fixed side plate 17 is fixedly installed on one side of the assembly frame 6, and one side of the fixed side plate 17 is fixed to limit and block the movement of the perfume bottle placement rack 8. A fixed shaft seat 18 is fixedly installed on the other side of the assembly frame 6. A movable side plate 19 is rotatably connected to the fixed shaft seat 18. A fixed buckle 20 is fixedly installed on the upper end of the movable side plate 19. The movable side plate 19 is movably installed on the assembly frame 6 through the fixed buckle 20. The movable side plate 19 rotates around the fixed shaft seat 18. The movable side plate 19 is fixed to the assembly frame 6 through the fixed buckle 20 to achieve the fixation of the movable side plate 19 after rotation, so as to achieve the fixation of the perfume bottle placement rack 8 after installation on the assembly frame 6. The movable side plate 19 is connected to the fixed shaft seat 18 through a rotating shaft. This connection method allows the movable side plate 19 to be able to flip around a specific axis. The platform formed by the flipping of the movable side plate 19 provides a stable support surface for the perfume bottle placement rack 8, so that the placement rack 8 It can remain level and stable during the installation process, making it convenient for installers to carry out subsequent installation operations, such as alignment and fixing.

[0038] The upper surface of the inner wall of the fixed shaft seat 18 and the upper surface of the inner wall of the U-shaped guide rail 7 are located in the same horizontal plane. After the movable side panel 19 rotates around the fixed shaft seat 18, the horizontal part of the fixed shaft seat 18 limits the rotation of the movable side panel 19 to ensure the stability of the movable side panel 19 after it rotates to a horizontal angle. At the same time, after the movable side panel 19 rotates, the upper surface and the U-shaped guide rail 7 form a supporting guide structure composed of the perfume bottle placement rack 8 and the guide wheel 9.

[0039] The perfume bottle rack 8 is provided with an auxiliary pull-out groove 801 , which assists in pulling out the perfume bottle rack 8 , making it convenient to remove the perfume bottles on the perfume bottle rack 8 after inspection.

[0040] A V-shaped guide opening 701 is provided on the side corresponding to the loading of the U-shaped guide rail 7, and a buffer pad 21 is provided on the side close to the unloading of the U-shaped guide rail 7. The buffer pad 21 is fixedly mounted on the side wall of the fixed side plate 17. The V-shaped guide opening 701 guides the movement of the guide wheel 9 and assists the insertion of the guide wheel 9 to ensure that the guide wheel 9 stably enters the U-shaped guide rail 7. The buffer pad 21 is composed of a spring and a buffer part. The guide wheel 9 is supported by the buffer pad 21. When the structure composed of the perfume bottle placement rack 8 and the guide wheel 9 slides in the U-shaped guide rail 7, the buffer pad 21 plays a buffering role to reduce the inertia of the movement of the structure composed of the perfume bottle placement rack 8 and the guide wheel 9.

[0041] A lower sealing leather pad 22 is fixedly installed on the upper surface of the rectangular lifting plate 11, and an upper sealing leather pad 23 is fixedly installed on the upper surface of the lower sealing leather pad 22. The structures composed of the lower sealing leather pad 22 and the upper sealing leather pad 23 can be deformed. The deformable design of the lower sealing leather pad 22 and the upper sealing leather pad 23 can ensure the contact effect between the lower sealing leather pad 22 and the upper sealing leather pad 23 and the upper surface of the color water detection box 1. A fixed mounting seat 24 is fixedly installed on the upper surface of the rectangular lifting plate 11, and a rotatable rod 25 is rotatably connected to the fixed mounting seat 24. One end of the rotatable rod 25 away from the fixed mounting seat 24 is fixedly installed on the upper surface of the upper sealing leather pad 23. The connection position of the rotatable rod 25 and the fixed mounting seat 24 is a U-shaped belt. The U-shaped belt has a certain flexibility and can adapt to a certain degree of relative displacement and angle change while transmitting power or movement between the rotatable rod 25 and the fixed mounting seat 24. The U-shaped belt can absorb and buffer the impact force and vibration during the movement to a certain extent, and protect the rotatable rod 25. The fixed mounting seat 24 and other parts connected thereto reduce wear and damage, and improve the stability and reliability of the entire system, which makes the connection more flexible and reduces the stress concentration caused by installation errors or component deformation. By rotating the rotatable rod 25 around the fixed mounting seat 24, the upper sealing leather pad 23 and the lower sealing leather pad 22 form a structure that tilts up, changing the contact effect between the lower sealing leather pad 22 and the upper surface of the color water detection box 1; The material of the lower sealing pad 22 and the upper sealing pad 23 can be natural rubber, nitrile rubber, fluororubber, etc. The rubber sealing pad has good elasticity, corrosion resistance and sealing performance, and is suitable for a variety of media and different operating temperature ranges to ensure its deformation ability without losing the sealing effect.

[0042] The lower sealing leather pad 22 is composed of an outer bendable ring 2201 on the outside and an inner fixed ring 2202 on the inside. The outer bendable ring 2201 is composed of four pieces, and the four-piece structure can form a rectangular frame-shaped outer bendable ring 2201, so that the outer bendable ring 2201 can be better hung on the top of the color water detection box 1 to improve the connection effect of the contact position between the lower sealing leather pad 22 and the color water detection box 1. The outer bendable ring 2201 is fixed on the inner fixed ring 2202 near the side of the inner fixed ring 2202, and the structure composed of the outer bendable ring 2201 and the inner fixed ring 2202 is placed on the contact position between the color water detection box 1 and the rectangular lifting plate 11.

[0043] The perfume bottle placement rack 8 is provided with a placement groove 802 corresponding to the perfume bottle, and a drainage groove 803 is provided at the bottom of the inner wall of the placement groove 802. A plurality of auxiliary fixing strips 804 are provided on the circumferential side of the inner wall of the placement groove 802, and the colored water is discharged through the drainage groove 803. The placement groove 802 is used to place the perfume bottle, and the auxiliary fixing strips 804 form a structure for fixing the perfume bottle. The perfume bottle is placed in the placement groove 802, and the perfume bottle is rotated to allow the auxiliary fixing strips 804 to be evenly wrapped around the outside of the perfume bottle. The elastic belt has a certain buffering effect, which can absorb and disperse the impact force when the perfume bottle is hit by an external force, thereby reducing the risk of the bottle breaking. The plurality of elastic belts can tightly fix the perfume bottle in the corresponding position, and the elastic belt can play a certain isolation role, reducing the direct contact between the perfume bottle and external objects, and preventing the bottle body from being scratched and worn.

[0044] A method for detecting air tightness of a screw-mouth perfume bottle, comprising the following steps: The first step: install the structure consisting of the perfume bottle placement rack 8 and the guide wheel 9 on the assembly frame 6, and the structure consisting of the perfume bottle placement rack 8 and the guide wheel 9 is placed on the horizontal assembly beam 5 and the assembly frame 6. The horizontal assembly beam 5 and the assembly frame 6 descend to reach the color water detection box 1, and the lower sealing leather pad 22, the upper sealing leather pad 23 and the rectangular lifting plate 11 seal the color water detection box 1. The corrugated exhaust pipe 13 is pressurized by the air compressor. After a vacuum space is formed in the color water detection box 1, the color water will enter the screw-mouth perfume bottle with a poor seal.

[0045] Step 2: After the vacuum negative pressure lasts for a period of time, the piston rod of the electric push rod 4 drives the structure composed of the horizontal assembly beam 5 and the assembly frame 6 to rise, and water is sprayed through the spray belt 12 to rinse the perfume bottles on the perfume bottle placement rack 8. After the rinsing is completed, the perfume bottles that have been tested are removed.

[0046] Working principle: Step 1: Install the bottle cap on the screw-mouth perfume bottle, place the perfume bottle with the bottle cap installed in the placement groove 802, rotate the perfume bottle, and multiple auxiliary fixing strips 804 are wrapped around the outside of the perfume bottle to fix the perfume bottle. After the perfume bottle to be tested is installed on the perfume bottle placement rack 8, it is necessary to install the structure composed of the perfume bottle placement rack 8 and the guide wheel 9 on the assembly frame 6, align the guide wheel 9 with the V-shaped guide opening 701, and guide the guide wheel 9 through the guidance of the V-shaped guide opening 701. Engage in the U-shaped guide rail 7 to achieve the movement and guidance of the structure composed of the perfume bottle placement rack 8 and the guide wheel 9. When the guide wheel 9 moves to the position of the buffer pad 21, the buffer pad 21 supports and buffers the guide wheel 9 to ensure the stability of the perfume bottle placement rack 8 and the guide wheel 9 after they stop moving. After the guide wheel 9 stops, the structure composed of the perfume bottle placement rack 8 and the guide wheel 9 stops on the U-shaped guide rail. On the rail 7, close the movable side panel 19, fix the two ends of the perfume bottle placement rack 8 by the movable side panel 19 and the fixed side panel 17, the piston rod of the electric push rod 4 drives the horizontal assembly beam 5 and the assembly frame 6 to descend, the horizontal assembly beam 5 and the assembly frame 6 descend to reach the color water detection box 1, and the rectangular lifting plate 11 is engaged with the inner wall of the color water detection box 1 near the top. At the same time, the lower sealing leather pad 22 and the upper sealing leather pad 23 form a structure corresponding to the gap between the color water detection box 1 and the rectangular lifting plate 11. The upper sealing leather pad 23 and the upper sealing leather pad 23 droop due to gravity in the gap between the color water detection box 1 and the rectangular lifting plate 11. In the process of the lower sealing leather pad 22 and the upper sealing leather pad 23 drooping due to gravity, the outer bendable ring 2201 also deforms to ensure the sealing effect of the contact position between the color water detection box 1 and the rectangular lifting plate 11.

[0047] Step 2: The corrugated exhaust pipe 13 is connected to the air compressor, and the air compressor is used to pressurize the corrugated exhaust pipe 13 to extract the gas in the color water detection box 1, and a vacuum space is formed in the color water detection box 1. After the vacuum space is formed in the color water detection box 1, when the connection position between the screw-mouth perfume bottle and the bottle cap is not well sealed, the color water will enter the screw-mouth perfume bottle, and the screw-mouth perfume bottle contains the color of the color water, thereby realizing the detection of the screw-mouth perfume bottle.

[0048] Step 3: After the vacuum negative pressure lasts for a period of time, the piston rod of the electric push rod 4 drives the structure composed of the horizontal assembly beam 5 and the assembly frame 6 to rise. The rise of the structure composed of the horizontal assembly beam 5 and the assembly frame 6 can drive the perfume bottle placement rack 8 and the guide wheel 9 to rise. After the structure composed of the horizontal assembly beam 5 and the assembly frame 6 leaves the colored water in the colored water detection box 1, water is sprayed through the spray belt 12 to rinse the perfume bottles on the perfume bottle placement rack 8. After the rinsing is completed, the perfume bottles that have been tested are removed.
