[0002] During the production of corrugated cardboard, the corrugated base paper needs to have certain pressure resistance, tensile strength, puncture resistance and folding resistance. If the humidity is too high, the paper will appear soft and have poor hardness, and the quality of fluting and bonding will also deteriorate accordingly.

The protective film includes a base paper, a PVC film and several attachment devices. The base paper has a top surface and a bottom surface that are relatively set. The top surface of the base paper is laminated to the back of the base paper layer. The base paper has a top surface and a bottom surface that are relatively set. The top surface of the PVC film is laminated to the back of the base paper. Several attachment devices are arranged on the back of the PVC film.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned existence mainly uses hygroscopic resistors or capacitive sensors as detection probes for non-contact online humidity detection. Its main disadvantages are slow response time, and the detection is only the humidity value at a certain point of the base paper, which cannot fully and accurately reflect the humidity condition of the base paper. In addition, there are also problems with detection accuracy and reliability. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 6 As shown, the present invention provides a humidity detection device for base paper production, including a support frame 1 and a protective shell 8. When the humidity of the paper is detected, the protective shell 8 needs to be pulled out and the cardboard is attached to the bottom end of the shell 4. At this time, the moisture of the paper enters the interior of the absorbent gauze 402 through the water inlet hole 401, and the absorbent gauze 402 absorbs the moisture into the interior of the super absorbent resin layer 403. When the super absorbent resin layer 403 is dry, it does not contact the elastic isolation layer 404. After absorbing water, the super absorbent resin layer 403 expands, causing pressure on the elastic isolation layer 404, thereby transmitting the pressure to the thermistor 405.

[0025] Specifically, a circular groove is provided inside the thermistor 405, and a magnetic ring 5 is attached to the inside of the circular groove of the thermistor 405. The super absorbent resin layer 403 expands after absorbing water, causing pressure on the elastic isolation layer 404, thereby transmitting the pressure to the thermistor 405. At this time, the thermistor 405 transmits current to the inside of the magnetic ring 5. At this time, the magnetic ring 5 that emits a magnetic field absorbs the magnetic pole 503 at the top of the substrate 504. The rotating magnetic pole 503 touches the magnetic ring 5, and the magnetic block 502 reacts with the light-emitting diode 501, and the light-emitting diode 501 lights up.

[0026] Furthermore, a pull rod 6 is provided for sliding inside the thermistor 405. The rotating rod 601 inside the pull rod 6 touches the super absorbent resin layer 403 and tilts. At this time, the first fixed block 602 on the outside of the rotating rod 601 drives the spring 603 to tilt until it touches the inside of the super absorbent resin layer 403 and slides out. Under the reaction of the spring 603 on the outside of the second fixed block 604, the rotating rod 601 is straightened and used for protective support for the super absorbent resin layer 403.

[0027] Furthermore, a square notch is provided on the inner wall of the top end of the thermistor 405 , and the rotating rod 601 is pressed against the inner wall of the square notch of the thermistor 405 , so as to facilitate the sliding of the rotating rod 601 and the thermistor 405 .

[0028] It is worth noting that a support leg 2 is provided on the outside of the support frame 1, and a roller 201 is sleeved on the outside of the support leg 2. The paper is placed on the outside of the roller 201 on the outside of the support leg 2 and one end of the paperboard is pulled out and placed inside the support frame 1.

[0029] It is worth noting that an operating table 7 is welded to the top of the supporting frame 1, and a display screen 701 is embedded inside the operating table 7. A buzzer 702 is provided at the bottom of the display screen 701, and the buzzer 702 is electrically connected to the substrate 504. The staff operates the detection equipment through the operating table 7 and detects the paper by watching and cooperating with the buzzer 702.

[0030] It is worth mentioning that a rotating base 3 is provided inside the supporting frame 1, and the protective shell 8 rotates inside the rotating base 3. There are two groups of protective shells 8, which are used to protect the outer shell 4 and prevent the inner shell 4 from being in contact with water vapor for a long time and causing damage to parts.

[0031] Working principle:

[0032] First, the staff places the paper on the outside of the roller 201 on the outside of the support leg 2 and pulls out one end of the cardboard and places it inside the support frame 1, and adjusts the height of the protective shell 8 inside the rotating base 3. When it is necessary to test the humidity of the paper, the protective shell 8 needs to be pulled out and the cardboard needs to be attached to the bottom end of the shell 4. At this time, the moisture of the paper enters the inside of the absorbent gauze 402 through the water inlet hole 401, and the absorbent gauze 402 will absorb it into the inside of the super absorbent resin layer 403. When the super absorbent resin layer 403 is dry, it does not contact the elastic isolation layer 404. The super absorbent resin The lipid layer 403 expands after absorbing water, exerting pressure on the elastic isolation layer 404, thereby transmitting the pressure to the thermistor 405. The thermistor 405 then transmits current to the interior of the magnetic ring 5. The magnetic ring 5, which now emits a magnetic field, attracts the magnetic pole 503 at the top of the substrate 504. The rotating magnetic pole 503 touches the magnetic ring 5, and the light-emitting diode 501 lights up. In conjunction with the buzzer 702 on the outside of the operating table 7 on the left side of the support frame 1, the display screen 701 inside the operating table 7 lights up, reminding the staff to pay attention to the current paper.

[0033] When the super absorbent resin layer 403 absorbs moisture from the cardboard for a long time, the super absorbent resin layer 403 becomes hard and its effect deteriorates. At this time, the thermistor 405 and the elastic isolation layer 404 are pulled out by the pull rod 6, and finally the super absorbent resin layer 403 is pulled out by friction. When installation is required, the pull rod 6 is inserted into the super absorbent resin layer 403. At this time, the rotating rod 601 inside the pull rod 6 touches the super absorbent resin layer 403 and tilts. At this time, the first fixed block 602 outside the rotating rod 601 drives the spring 603 to tilt until it touches the inside of the super absorbent resin layer 403 and slides out. Under the reaction of the spring 603 outside the second fixed block 604, the rotating rod 601 is straightened and used to protect and support the super absorbent resin layer 403.
