Description

Technical Field

[0001] This utility model relates to the technical field of pressure measuring devices for aerosol cans, and in particular to an automatic pressure measuring device for aerosol cans. Background Technology

[0002] Aerosol cans need to be filled with a certain pressure, but the products themselves do not have pressure indicators. During the production process, operators cannot visually determine whether the product pressure is qualified. Currently, can pressure testing is mainly carried out by workers using pressure gauges. This method is time-consuming, very inefficient, and requires workers to stand next to the production line for a long time.

[0003] For example, Chinese utility model patent CN209372293U discloses an aerosol can internal pressure detection device, including a horizontally placed fixed plate. A cylinder is mounted on the fixed plate, and the piston rod of the cylinder is set downward and connected to a mounting bracket. A front end sleeve is provided at the front end of the mounting bracket. A pressure measuring head with a concave upper part is fitted inside the front end sleeve. A pressure transmitter is installed inside the pressure measuring head. The head of the pressure transmitter is installed in the concave structure of the pressure measuring head. Furthermore, a pressure measuring protrusion is provided at the lower end of the pressure measuring head, and a pressure measuring port is provided at the end of the pressure measuring protrusion. In this utility model, the aerosol can is fixed and stabilized by a clamping device during testing, and the internal pressure of the aerosol can is tested in the vertical direction. Therefore, when the aerosol can is put in and taken out, it is necessary to wait for the corresponding clamping device to finish moving before it can be replaced. The waiting time for replacing two aerosol cans results in low testing efficiency. Utility Model Content

[0021] like Figures 1 to 3 As shown, in this embodiment, the present invention includes a fixed frame 1, with a support rod assembly 2 for placing an aerosol can inclinedly arranged in the middle of the fixed frame 1; an adjustment and detection assembly 3, which is detachably connected to the upper part of the fixed frame 1; a pushing assembly 4, which is fixedly connected to the lower part of the support rod assembly 2; at least two positioning detection elements 5, and several positioning detection elements 5 are fixedly connected to the middle of the support rod assembly 2; the inclination angles of the adjustment and detection assembly 3 and the pushing assembly 4 are parallel to the support rod assembly 2, and a control screen 6 for controlling the detection process is fixedly connected to one side of the support rod assembly 2.

[0022] Specifically, the control panel 6 is equipped with a touch screen, which is used to display the status of the pressure sensor 33, the real-time pressure value detected, the pressure value setting range, etc. The pressure value can be set by directly clicking the corresponding position on the touch screen to set the required parameters; the pressure detection is based on the actual reading and makes corresponding feedback, such as judging whether the real-time pressure value of the pressure sensor 33 is qualified, using the position sensor to judge whether there is an aerosol can on the support rod group 2, and controlling the extension and retraction of the push drive device 42.

[0023] A compressed air control box is provided on the rear side of the fixed frame 1. The compressed air control box is provided with a first air outlet and a second air outlet. Both the first air outlet and the second air outlet are connected to the push drive device 42 and are used to control the extension and retraction of the push drive device 42. The extension and retraction of the push drive device 42 can be controlled by the control panel 6 controlling the air outlet sequence of the first air outlet.

[0024] The positioning sensor is an infrared sensor used to detect aerosol cans. The positioning detection component 5 is equipped with a fixing plate, which is fixed to the middle of the support rod assembly 2. It detects whether there is a product to be tested on the support rod assembly 2. The control panel 6 only controls the push drive device 42 to extend and start pressure measurement after both positioning sensors have detected the aerosol can. This prevents the push drive device 42 from extending before the product is properly placed, thus avoiding the situation where the aerosol can is jammed or damaged.

[0025] The system employs an inclined support rod assembly 2. When the aerosol can is placed in, it adheres tightly to the support rod assembly 2 under its own weight. Once the positioning sensor detects the placement of the aerosol can, the control panel 6 controls the push-drive device 42 to extend and begin pressure measurement. After the pressure measurement is completed, the pressure of the aerosol can is displayed on the control panel 6. The control panel 6 then controls the push-drive device 42 to retract, releasing the aerosol can from its lock. After the lock is released, the staff can remove the aerosol can. The pressure measurement process is simple and efficient. The inclined support rod assembly 2 improves the efficiency of aerosol can placement and positioning, and shortens the waiting time for replacing two aerosol cans.

[0030] Specifically, the regulating valve 32 is a right-angle two-way valve. A sliding plate that slides with the regulating seat 31 is provided on the rear side of the regulating valve 32. The sliding plate is locked and positioned with the sliding rod 313 of the regulating seat 31 by screws, so as to realize the adjustment of the front and rear displacement of the regulating valve 32.

[0031] like Figure 5 As shown, in this embodiment, the adjusting seat 31 includes a positioning rod 311, a connecting rod 312, and a sliding rod 313.

The sliding rod 313 is inclinedly disposed at the other end of the connecting rod 312. The upper surface of the sliding rod 313 is provided with a groove that slides with the adjusting valve 32.

[0032] Specifically, the positioning rod 311, connecting rod 312, and sliding rod 313 are all square rods. The positioning rod 311, connecting rod 312, and sliding rod 313 are all provided with slots. The positioning rod 311 is detachably connected to the height adjustment rod 12 by screws.

One end of each support rod 21 is fixedly connected to the bottom frame 11, and the other end of each support rod 21 is fixedly connected to the height adjustment rod 12. The limiting rod 22 is fixedly connected to the upper part of the two support rods 21, and the limiting rod 22 is in a limiting cooperation with the adjustment detection component 3.

[0036] Specifically, the staff can control the front and rear positions of the limit rod 22 to limit the height of the adjusting seat 31, making adjustment convenient.
