When the vacuum packaging bag is completely submerged by water in the storage frame 6, the electric push rod 7 of the test frame 4 is controlled to move to the side close to the vacuum packaging bag, then the pressure head 5 at the telescopic end of the electric push rod 7 can be slowly pressed on the end face of the vacuum packaging bag, and the vacuum packaging bag is subjected to light pressure treatment;
after one-time detection is completed, the test frame 4 and the vacuum packaging bag are far away from the storage frame 6 through the driving mechanism, and at the moment, the second electric telescopic rod 10 is controlled to drive the sponge strip 11 to move downwards, so that the sponge strip 11 is attached to the surface of the vacuum packaging bag, the sponge strip 11 adsorbs water on the surface of the vacuum packaging bag, and the problem that the continuous use of the vacuum packaging bag is affected due to excessive water on the surface of the vacuum packaging bag is avoided;
it should be noted that, in the initial state, the sponge strip 11 is located at the upper side of the outer wall of the test frame 4, and the height of the test frame 4 is greater than the height of the water in the storage frame 6, so as to avoid the problem that the sponge strip 11 is in contact with the water when the test frame 4 is located in the water, so that the water is difficult to adsorb on the surface of the vacuum packaging bag in the following steps; when the vacuum packaging bag is separated from the storage frame 6 and the sponge strip 11 adsorbs water on the surface of the vacuum packaging bag, the rotary shaft 13 is driven to rotate by controlling the external motor, and the rotary shaft 13 drives the fan 14 to rotate, so that wind generated by the fan 14 blows to the surface of the vacuum packaging bag, the water on the surface of the vacuum packaging bag is removed as soon as possible, and the subsequent use of the vacuum packaging bag is facilitated;
after the water on the surface of the vacuum packaging bag is removed, when the second electric telescopic rod 10 drives the sponge strip 11 to restore to the initial position, the telescopic end of the second electric telescopic rod 10 and the sponge strip 11 can penetrate through the contracted circular frame 16, and the diameter formed by the sponge strip 11 is larger than that of the contracted circular frame 16 due to the fact that the circular array is formed, the sponge strip 11 can be extruded by the contracted circular frame 16, water in the sponge strip 11 is extruded and removed, and the subsequent reuse of the sponge strip 11 is facilitated.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
