Description

Technical Field

[0001] This application relates to the field of aerosol can testing technology, and in particular to an aerosol can strength testing device. Background Technology

[0002] Aerosol cans use internal pressure to convert gaseous substances into liquid for storage, which is then expelled as gas. After filling, the internal pressure increases, posing a risk of rupture. Current testing procedures require filling the aerosol can with water and then evacuating it after the test, a time-consuming process that reduces testing efficiency.

[0003] To address the aforementioned issues, a detection device has emerged. For example, Chinese Utility Model No. CN220932309U discloses an airtightness testing device for aerosol cans. This device includes a chassis, with an aerosol can container rotatably mounted on one side of the top of the chassis. Multiple evenly distributed slots are formed in the center of the aerosol can container. A bracket is fixedly mounted on one side of the chassis, and a cylinder is fixedly mounted on the top of the bracket. The output end of the cylinder passes through the bracket and is connected to a connecting seat. This airtightness testing device utilizes a pressure sensor to detect the internal air pressure and perform airtightness testing on the aerosol cans, thereby improving product quality. During testing, multiple aerosol cans to be tested are first placed in the slots of the aerosol can container for batch testing. Rotating the aerosol can container accelerates the leakage rate, shortens the testing time, and improves testing efficiency. When a leak is detected, the aerosol cans in the current batch are tested one by one to identify the individual leaking can, ensuring testing accuracy. However, the above-mentioned device only realizes "batch initial inspection alarm". After the initial inspection finds a leak, it is necessary to manually remove each aerosol can in the batch for re-inspection, which leads to a bottleneck in detection efficiency. In addition, manual operation is prone to can confusion and secondary damage. Therefore, an aerosol can strength detection device is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this application is to propose an aerosol can strength testing device to solve the problem of difficulty in picking up parts in traditional equipment. After the initial inspection finds a leak, it is necessary to manually remove each aerosol can in the batch for re-inspection, which leads to a bottleneck in testing efficiency. In addition, manual operation is prone to can confusion and secondary damage.

[0005] To achieve this objective, the following technical solution is adopted in this application: An aerosol can strength testing device includes a testing platform, an aerosol can container, a mounting frame, a pressing mechanism, a testing cover, and an audible and visual alarm. The aerosol can container is located at the top of the testing platform, the mounting frame is fixed on the testing platform, the pressing mechanism is located on the mounting frame, and the pressing end of the pressing mechanism is connected to the testing cover. The testing cover is located above the aerosol can container. The aerosol can container has multiple can slots. The audible and visual alarm is located on the testing platform. The device also includes multiple sealed chambers with bottom openings. The sealed chambers are located at the bottom of the testing cover. The number of sealed chambers is the same as the number of can slots and they correspond one-to-one. A first air pressure sensor is installed on the top wall of each sealed chamber. The audible and visual alarm and the multiple first air pressure sensors are electrically connected to a display and control module.

[0006] As a preferred embodiment of the present invention, the aerosol can strength testing device further includes a plurality of first sealing rings and a plurality of second sealing rings. The first sealing rings are disposed at the bottom edge of each of the sealed chambers, and the second sealing rings are disposed on the upper surface of the aerosol can container. The second sealing rings surround the perimeter of each can groove, and the number of second sealing rings is the same as that of the first sealing rings and they correspond one-to-one.

[0007] As a preferred embodiment of the present invention, the aerosol can strength testing device further includes a rotating mechanism, which includes a mounting plate and a motor. The mounting plate is fixed below the testing platform, and the motor is mounted on the mounting plate. The output shaft of the motor is vertically arranged and passes through the mounting plate and is coaxially connected to the aerosol can container. An upper limit ring and a lower limit ring are provided at intervals on the outer periphery of the aerosol can container. The aerosol can container is rotatably connected to the testing platform through a bearing, and the bearing is located between the upper limit ring and the lower limit ring. The pressing end of the pressing mechanism is rotatably connected to the testing cover.

[0008] As a preferred embodiment of the present invention, the pressing mechanism includes a telescopic cylinder and a bearing seat. The telescopic cylinder is mounted on the mounting frame, and the telescopic rod of the telescopic cylinder is vertically arranged and rotatably connected to the detection cover through the bearing seat.

[0009] As a preferred embodiment of the present invention, a third sealing ring is provided at the bottom edge of the detection cover, and a fourth sealing ring corresponding to the third sealing ring is provided on the aerosol can container.

[0010] As a preferred embodiment of the present invention, the aerosol can strength detection device further includes a plurality of second air pressure sensors, which are spaced apart and disposed on the top wall of the detection cover, and are electrically connected to the display and control module.

[0011] As a preferred embodiment of the present invention, it further includes multiple elastic positioning components, with each of the can slots having one of the elastic positioning components to position and fix the aerosol can placed in the can slot.

[0012] As a preferred embodiment of the present invention, the elastic positioning component includes multiple elastic clips, multiple arc-shaped contact portions, and multiple springs. One end of each elastic clip is fixedly connected to the inner wall of the tank, and the other end of each elastic clip is a free end. All the elastic clips are evenly distributed along the circumferential direction of the inner wall of the tank. The free end of each elastic clip is fixedly connected to a corresponding arc-shaped contact portion. One end of each spring is connected to a corresponding arc-shaped contact portion, and the other end of each spring is connected to the inner wall of the tank.

[0013] As a preferred embodiment of the present invention, all the arc-shaped contact portions naturally enclose a circular space, the diameter of which is smaller than the outer diameter of the placed aerosol can.

[0014] As a preferred embodiment of the present invention, the elastic positioning component further includes a plurality of anti-slip pads, which are disposed one-to-one on the surface of the arc-shaped contact portion, and the surface of the anti-slip pads is provided with anti-slip texture.

[0015] Compared to existing technologies, the beneficial effects of this application are: 1. Place multiple aerosol cans to be tested in the canister slot. The pressing mechanism moves the test cover and sealing chamber downwards, gradually sealing the aerosol cans inside the chamber until they are located in the sealed space formed by the chamber and the canister. Each sealed space has a first pressure sensor for real-time monitoring. When a significant change in the detected pressure is detected, the first pressure sensor transmits this signal to the display and control module. The display and control module then controls the audible and visual alarm to sound and light up to notify the staff. The staff can then see which aerosol can in the sealed chamber is leaking through the display screen on the display and control module, greatly improving the staff's testing efficiency.

[0016] 2. The combined use of the first and second sealing rings can greatly improve the sealing performance of the sealed space formed between the sealing chamber and the aerosol can container.

[0017] 3. Start the motor. The motor's output torque is transmitted to the aerosol can container through the coupling. Since the aerosol can container is rotatably connected to the test stand through the bearing, the aerosol can container can rotate on the test stand. The rotation of the aerosol can container can accelerate the movement of the substance inside the can placed in the can slot. If there is a leak in the aerosol can, it can accelerate the leakage of the substance inside the aerosol can, thereby improving the detection efficiency and accuracy.

[0018] 4. The combined use of the third and fourth sealing rings greatly improves the sealing performance of the space formed between the detection cap and the aerosol can container. The second pressure sensor can monitor the sealing condition of the space in real time. When a significant change in the detection pressure is detected, this signal is transmitted to the display and control module. The display and control module will then control the audible and visual alarm to sound an alarm and illuminate the warning light to notify the staff. The staff can then see on the display screen which second pressure sensor detected the increased pressure in the vicinity, thus prioritizing the detection of the corresponding aerosol cans in the corresponding slots. This provides secondary monitoring and significantly improves the speed at which staff can select aerosol cans. Attached Figure Description

[0026] Example 1: Figure 1 and Figure 4 This invention provides an aerosol can strength testing device, including a testing platform 1, an aerosol can container 2, a mounting frame 3, a pressing mechanism, a testing cover 4, and an audible and visual alarm. The aerosol can container 2 is located at the top of the testing platform 1, the mounting frame 3 is fixed on the testing platform 1, the pressing mechanism is located on the mounting frame 3, and the pressing end of the pressing mechanism is connected to the testing cover 4. The testing cover 4 is located above the aerosol can container 2. The aerosol can container 2 has multiple can slots 5. The audible and visual alarm is located on the testing platform 1. The device also includes multiple sealed chambers 6 with bottom openings. The sealed chambers 6 are located at the bottom of the testing cover 4. The number of sealed chambers 6 and can slots 5 are the same and correspond one-to-one. A first air pressure sensor 7 is installed on the top wall of each sealed chamber 6. The audible and visual alarm and the multiple first air pressure sensors 7 are electrically connected to a display and control module.

[0027] In this embodiment, multiple aerosol cans to be tested are placed in the canister 5. The pressing mechanism moves the test cover 4 and the sealing chamber 6 downwards, and the aerosol cans gradually enter the sealing chamber 6 until they are located in the sealed space formed by the sealing chamber 6 and the aerosol can container 2. Each sealed space is monitored in real time by a first air pressure sensor 7 (model DBT500). When a large change in the detected air pressure is detected, the first air pressure sensor 7 transmits this signal to the display and control module (model NANO-1421). The display and control module then controls the sound and light alarm 14 (model Shengsaier P2475RLZ) to emit an alarm sound and light to notify the staff. The staff can see from the display screen on the display and control module which aerosol can in the sealing chamber 6 is leaking, which greatly improves the staff's detection efficiency.

[0028] Preferably, such as Figure 1 As shown, the aerosol can strength testing device also includes multiple first sealing rings 81 and multiple second sealing rings 82. The first sealing rings 81 are located at the bottom edge of each sealing chamber 6, and the second sealing rings 82 are located on the upper surface of the aerosol can container 2. The second sealing rings 82 surround each can groove 5, and the number of second sealing rings 82 is the same as that of the first sealing rings 81 and they correspond one-to-one.

[0029] In this embodiment, as one implementation method, the combined use of the first sealing ring 81 and the second sealing ring 82 can greatly improve the sealing performance of the sealed space formed between the sealing chamber 6 and the aerosol can container 2.

[0030] Example 2: Preferably, as another embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the aerosol can strength testing device also includes a rotating mechanism, which includes a mounting plate 91 and a motor 92. The mounting plate 91 is fixed below the testing platform 1, and the motor 92 is mounted on the mounting plate 91. The output shaft of the motor 92 is vertically arranged and passes through the mounting plate 91 and is coaxially connected to the aerosol can container 2. The outer periphery of the aerosol can container 2 is provided with an upper limit ring 93 and a lower limit ring 94 spaced apart. The aerosol can container 2 is rotatably connected to the testing platform 1 through a bearing 95. The bearing 95 is located between the upper limit ring 93 and the lower limit ring 94. The pressing end of the pressing mechanism is rotatably connected to the testing cover 4.

[0031] In this embodiment, as one implementation method, the motor 92 is started, and the output torque of the motor 92 is transmitted to the aerosol can container 2 through the coupling. Since the aerosol can container 2 is rotatably connected to the detection table 1 through the bearing 95, the aerosol can container 2 can rotate on the detection table 1. The rotation of the aerosol can container 2 can accelerate the movement of the substance inside the aerosol can placed in the can slot 5. If there is a leak in the aerosol can, it can accelerate the leakage of the substance inside the aerosol can, thereby improving the detection efficiency and detection accuracy.

[0032] Specifically, such as Figure 5 As shown, the pressing mechanism includes a telescopic cylinder 101 and a bearing seat 102. The telescopic cylinder 101 is mounted on the mounting bracket 3, and the telescopic rod of the telescopic cylinder 101 is vertically arranged and rotatably connected to the detection cover 4 through the bearing seat 102. The telescopic cylinder 101 is a hydraulic cylinder or an electric cylinder.

[0033] When the telescopic cylinder 101 is activated, the telescopic rod of the telescopic cylinder 101 extends and retracts, which can drive the bearing seat 102 and the detection cover 4 to move up and down.

[0034] Example 3: Preferably, as another embodiment of the present invention, such as Figure 1 As shown, a third sealing ring 111 is provided at the bottom edge of the detection cover 4, and a fourth sealing ring 112 corresponding to the third sealing ring 111 is provided on the aerosol can container 2.

[0035] In this embodiment, as one implementation method, the combined use of the third sealing ring 111 and the fourth sealing ring 112 can greatly improve the sealing performance of the sealed space formed between the detection cover 4 and the aerosol can container 2.

[0036] Preferably, such as Figure 4As shown, the aerosol can strength detection device also includes multiple second air pressure sensors 12, which are spaced apart and disposed on the top wall of the detection cover 4. All of the multiple second air pressure sensors 12 are electrically connected to the display and control module.

[0037] There are 5-7 DBT500 second pressure sensors 12, and the array of second pressure sensors 12 is distributed on the top wall of the detection cover 4. The second pressure sensors 12 are evenly distributed along the circumference of the inner wall of the detection cover 4. The angle formed by the line connecting two adjacent second pressure sensors 12 and the center of the detection cover 4 is 60°-90°. The projection position of each second pressure sensor 12 is aligned with the center of 1-2 canister slots 5 to ensure that each canister slot 5 area corresponds to at least one sensor. The second pressure sensors 12 can monitor the sealing of the sealed space formed by the detection cover 4 and the aerosol can container 2 in real time. When a large change in the detected pressure data is detected, this signal can be transmitted to the display and control module. The display and control module will control the sound and light alarm 14 to emit an alarm sound and alarm light to inform the staff. The staff can see which second pressure sensor 12 detected the increase in nearby pressure through the display of the display and control module, so as to prioritize the detection of the aerosol cans placed in the corresponding canister slots 5, which plays a role in secondary monitoring and greatly improves the speed of staff screening aerosol cans.

[0038] Example 4: Preferably, as another embodiment of the present invention, such as Figure 1-3 As shown, it also includes multiple elastic positioning components, with one elastic positioning component in each can slot 5 to position and fix the aerosol can placed in the can slot 5. More specifically, the elastic positioning component includes multiple elastic clips 131, multiple arc-shaped contact portions 132, and multiple springs 133. One end of the elastic clip 131 is fixedly connected to the inner wall of the can slot 5, and the other end of the elastic clip 131 is a free end. All the elastic clips 131 are evenly distributed along the circumferential direction of the inner wall of the can slot 5. The free end of each elastic clip 131 is fixedly connected to a corresponding arc-shaped contact portion 132. One end of each spring 133 is connected to a corresponding arc-shaped contact portion 132, and the other end of each spring 133 is connected to the inner wall of the can slot 5.

[0039] In this embodiment, as one implementation method, when the aerosol can is placed in the can slot 5, the elastic clip 131 is stretched open and the spring 133 is compressed. The radial clamping force is generated by its own elastic force and the elastic force of the spring 133 to clamp and fix the aerosol can, so as to prevent the aerosol can from shifting or colliding when the aerosol can container 2 rotates, and to ensure the integrity of the aerosol can and the accuracy of the airtightness test.

[0040] Preferably, when the spring 133 is in an uncompressed state, the arc-shaped contact portion 132 is also in a natural state, and all the arc-shaped contact portions 132 in the natural state enclose a circular space, the diameter of which is smaller than the outer diameter of the placed aerosol can.

[0041] Specifically, the diameter of the circular space formed by all the arc-shaped contact parts 132 in their natural state is 2-3 mm smaller than the outer diameter of the aerosol can, so as to ensure that the can is clamped by elastic force after it is placed in.

[0042] Preferably, the elastic positioning component further includes a plurality of anti-slip pads, which are disposed one-to-one on the surface of the arc-shaped contact portion 132, and the surface of the anti-slip pads is provided with anti-slip texture.

[0043] The anti-slip mat is made of silicone and fits tightly against the surface of the aerosol can without gaps.

[0044] Working principle of the invention: Multiple aerosol cans to be tested are placed in the canister 5. The telescopic cylinder 101 is activated, and the telescopic rod of the telescopic cylinder 101 extends and retracts, causing the bearing seat 102 and the test cover 4 to move up and down. The aerosol cans gradually enter the sealed chamber 6 until they are located in the sealed space formed by the sealed chamber 6 and the aerosol can container 2. Each sealed space is monitored in real time by a first air pressure sensor 7. When a large change in the detected air pressure is detected, the first air pressure sensor 7 will transmit this signal to the display and control module. The display and control module will control the audible and visual alarm 14 to emit an alarm sound and alarm light to notify the staff. The staff can see which aerosol can in the sealed chamber 6 is leaking through the display screen on the display and control module, which greatly improves the staff's testing efficiency.
