Description
Technical Field
[0001] This utility model belongs to the field of pressure testing technology, and in particular relates to a pressure testing machine for sealed packaging. Background Technology
[0002] In the early days, pressure testing of sealed packaging often relied on manual operation or relatively simple non-automated equipment. It was difficult to accurately control parameters such as the magnitude, direction, and duration of pressure applied manually. Different operators had different operating techniques, which could lead to inconsistent test results for the same package. It was impossible to accurately determine whether the packaging could withstand the corresponding pressure under actual working conditions. At the same time, some packages may be at risk of rupture or explosion during high-pressure testing. Close manual operation could easily cause safety accidents and injuries to operators. Therefore, a pressure testing machine for sealed packaging was proposed. Utility Model Content

The outer surface of the lead screw 214 is connected to the inside of the sensor 213. Four limit rods 215 are installed on the left side of the sensor 213. All four limit rods 215 are cylindrical and have smooth surfaces.
[0022] The water injection assembly 22 includes a water pump 221, with a water storage tank 222 located below the water pump 221. The bottom of the water pump 221 is connected to the top of the water storage tank 222 via a bracket.

At the same time, the automatic water filling system can adjust the water addition in real time based on the data fed back by the sensor 213, keeping the pressure within a suitable detection range, further improving the accuracy and convenience of detection.
[0023] The extrusion assembly 23 includes a pressure detector 231. A fixing plate 232 is provided on the left side of the pressure detector 231. The right side of the fixing plate 232 contacts the left side of the pressure detector 231. The outer ring of the fixing plate 232 is connected to the inner wall of the machine body 111. A left force-measuring contact plate 235 is connected to the right side of the pressure detector 231.

[0024] The bottom of the placement plate 238 is connected to the inner wall of the main body 111. A crossbar 233 is connected to the top of the left force-measuring contact plate 235 and the right movable force-measuring contact plate 236.

[0025] A specific application of this embodiment is as follows: In use, firstly, the visible flip cover 112 is flipped upwards and opened. Then, the package to be tested is placed on the placement plate 238. Next, the package is connected to the water outlet of the water pump 221. Finally, the visible flip cover 112 is closed. Then, the servo motor 211 is started to drive the lead screw 214 to rotate. At the same time, the mounting plate 212 provides a certain support force for the servo motor 211 by welding it to the partition 234. During the rotation of the lead screw 214, the sensor 213 will move to the left. During the movement of the sensor 213, multiple limit rods 215 will move together. At this time, the multiple limit rods 215 will slide inside the right partition 234. At the same time, the multiple limit rods 215 provide a certain limit to the movement trajectory of the sensor 213. During the movement of the limit rods 215, the right movable force measuring contact plate 236 will move. At this time, the right movable force measuring contact plate 236 will move to the left along the crossbar 233. As the package moves, the right movable force-measuring contact plate 236, in conjunction with the left force-measuring contact plate 235, will compress the package. Simultaneously, the pressure detector 231 detects the pressure data of the package in real time and transmits the data to the pressure detection instrument 114 for the operator to observe. The operator can also observe the status of the package through the visual flip cover 112. During the detection process, the PLC 113, as the core control system of the equipment, continuously receives and processes signals from various sensors. These signals may include pressure values, force magnitude, position information, speed data, etc. The PLC 113 analyzes and processes these signals according to the preset program to determine the current status and future trend of the equipment. Through the action of the servo motor 211 and the sensor 213, the precision control of the force is greatly improved. Compared with traditional manual operation, the compressive strength of the package is detected more accurately. At the same time, automatic pressurization also reduces the risk of injury to the operator and the package. Meanwhile, during the inspection of the package, the water resources inside the water storage tank 222 are transported into the package by the water pump 221. Compared with the traditional manual water addition, this reduces the pressure fluctuation caused by inaccurate water addition. At the same time, the automatic water addition system can adjust the water addition in real time according to the data fed back by the sensor 213, so that the pressure is always within the appropriate detection range, further improving the accuracy and convenience of the inspection.
