Detailed Description

The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific working procedures are given, but the scope of the present invention is not limited to the following embodiments.

As shown in figures 1 and 2, the rain test device for the packing box comprises a spraying mechanism and a test unit. Specifically, the spraying mechanism comprises a water tank 1 and a water supply pipe 2 connected with the water tank, a water pump 3, a filter 4, an electromagnetic regulating valve 5, a vortex flowmeter 6 and a spraying head 7 positioned above the packaging box M to be detected are arranged on the water supply pipe 2, and the spraying head 7 adopts a shower head with a universal joint in order to achieve the effect of full spraying. In order to reduce the water consumption for testing, a return tank 8 is arranged below the spray head 7, and a return pipe 9 connected with the water tank 1 is arranged in the return tank 8. Meanwhile, in order to avoid corrosion of the packaging box M to be tested when immersed in water in the reflux tank 8 for a long time, a support 10 for supporting the packaging box M to be tested is further installed in the reflux tank 8, and a rubber anti-slip surface is further arranged on a contact surface between the support 10 and the packaging box M to be tested. Further, in order to prevent water sprayed from the shower head 7 from scattering outside the return tank 8 and contaminating the floor surface, a housing 11 having a drain pipe at the bottom is attached outside the shower head 7 and the return tank 8. The drain pipe is used to drain moisture from the inside of the housing 11 during the test.

The test unit comprises an in-box humidity sensor 12 mounted inside the packaging box M to be tested, and a processor 13, a display screen 14 and an ambient humidity sensor 15 mounted outside the housing 11. The processor 13 may be a single chip microcomputer or a PLC. When the humidity sensor 12 is installed in the box, a sealing structure is required to be provided at the connection between the humidity sensor and the box to prevent rainwater from infiltrating. For example, a wire mounting hole is formed in the side surface of the packaging box M to be tested, the in-box humidity sensor 12 is placed in the box, a wire connected with the in-box humidity sensor 12 is led out of the box through the mounting hole, and then sealant is applied around the mounting hole.

During operation, the water pump 3 is started, water flow in the water supply pipe 2 is monitored in real time through the vortex flowmeter 6, and after the processor 13 receives water flow data information sent by the vortex flowmeter 6, control data are sent to the electromagnetic regulating valve 5 according to preset parameters, so that the spraying water quantity of the spraying head 7 is regulated, and the water pump is used for simulating rainy days such as light rain, medium rain and heavy rainstorm. The in-box humidity sensor 12 and the ambient humidity sensor 15 are used for monitoring humidity conditions inside the box and outside the housing 11 (i.e., the atmospheric environment) in real time, and sending detected humidity data information to the processor 13, and the processor 13 sends the received humidity data information to the display screen 14 and displays the information on the display screen in real time. And comparing the humidity data inside and outside the box body by the staff, and judging whether the packing box leaks water according to the difference value.

It should be noted that in the description of the present invention, terms of orientation or positional relationship such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
