Pressure testing is primarily used to verify the film's sealing properties. By applying a certain pressure, the film is observed for leaks, cracks, and other signs, thereby determining the effectiveness of the seal.

[0003] Currently, the structure of traditional electronic withstand voltage test devices on the market is often complex and the operation steps are cumbersome, which is not conducive to workers performing withstand voltage tests on food packaging films. Therefore, there is an urgent need for an electronic withstand voltage test device with a simple structure and easy operation. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-5 The electronic withstand voltage test device includes a base 1, a detachable pressure measuring platform 3 is mounted on the top of the base 1, and guide posts 4 are fixedly arranged vertically on both sides of the pressure measuring platform 3 on the base 1, and the tops of the guide posts 4 are fixedly connected to the top plate 41. A screw rod 6 is rotatably arranged below the top plate 41, and a movable plate 5 is vertically movable at the bottom of the top plate 41. The screw rod 6 passes through the movable plate 5, and a pressure measuring plate 52 is fixedly arranged below the movable plate 5.

[0021] Connecting plates 51 are fixed downwardly on both sides of the bottom of the movable plate 5, and the bottoms of the connecting plates 51 are fixedly connected to the tops of the pressure measuring plates 52. The provision of the connecting plates 51 can securely connect the movable plate 5 and the pressure measuring plates 52, allowing the pressure measuring plates 52 to move synchronously with the movable plate 5.

[0022] The movable plate 5 has a threaded hole in the middle corresponding to the screw rod 6, and the movable plate 5 is guided by the guide posts 4 on either side. The rotation of the screw rod 6 drives the movable plate 5 vertically. It is also worth noting that a conventional damping mechanism is provided between the screw rod 6 and the threaded hole to prevent the screw rod 6 from rotating when not in use. The screw rod 6 can only rotate when the user turns the handle 62.

[0023] A fixing post 61 is fixed to the top of the screw rod 6, and a through hole is provided on the top plate 41 corresponding to the fixing post 61. A handle 62 is installed on the top of the fixing post 61. The fixing post 61 allows the screw rod 6 to be assembled on the top plate 41. When the screw rod 6 rotates, the fixing post 6 rotates synchronously in the through hole on the top plate 41.

[0024] Among them, mounting parts 31 are fixed downward on both sides of the bottom of the pressure measuring platform 3, and mounting cavities 11 are adapted to be opened on the corresponding mounting parts 31 on the base 1. Screw mounting plates 32 are fixed on both sides of the pressure measuring platform 3, and screw holes are adapted to be opened on the corresponding screws on the base 1.

[0025] A control panel 2 is fixed to one side of the top of the base 1 and is connected to the pressure platform 3 and pressure plate 52 via electrical signals. A load cell 33, model BK-3A-5kg, is mounted on the top of the pressure platform 3. The pressure plate 52 is equipped with a conventional pressure sensing module to measure the pressure of the food packaging film. The pressure measurement information is transmitted via electrical signals and displayed on the control panel 2. It is worth noting that the specific structure and operating principles of the control panel 2, pressure platform 3, and pressure plate 52 are all conventional and therefore will not be elaborated upon.

[0026] In this embodiment, when a user needs to measure the pressure of a food packaging film, they simply place the food packaging film on the pressure measuring platform 3. The user then rotates the screw 6 using the handle 62, thereby driving the movable plate 5 downward. This movement of the screw 6 drives the pressure measuring plate 52 to move downward synchronously, allowing the pressure measuring plate 52 to press the food packaging film. The load cells 33 and pressure sensing modules on the pressure measuring platform 3 and pressure measuring plate 52 can then detect the pressure of the food packaging film, with the detection data transmitted to the control panel 2 via electrical signals.

[0027] Furthermore, the pressure platform 3 in this device is a detachable structure, allowing users to replace the pressure platform 3 with different sizes according to actual usage needs. When assembling the pressure platform 3, the user only needs to insert the mounting member 31 at the bottom of the pressure platform 3 into the corresponding mounting cavity 11 on the base 1. At this time, the screw mounting plates 32 on both sides of the pressure platform 3 are in contact with the base. The user only needs to insert the screws through the through holes of the screw mounting plates 32 and into the screw holes on the base 1 to complete the installation of the pressure platform 3. After installation is complete, the pressure platform is powered on so that it can control the panel 2 through electrical signal connections.

[0028] In the present invention, the rotation of the screw rod 6 can drive the movable plate 5 to move vertically, thereby driving the pressure measuring plate 52 to move synchronously, so that the pressure resistance test of the food packaging film can be achieved through the pressure measuring platform 3 and the pressure measuring plate 52. This detection method is simple to operate and is convenient for users to test food packaging films.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
