Description

Technical Field

[0001] The utility model relates to the technical field of cardboard production, in particular to a cardboard moisture control device. Background Art

[0002] Cardboard, also known as board paper, is a thick paper sheet made of various pulp processed and composed of interwoven fibers. The difference between cardboard and paper is usually distinguished by basis weight and thickness. Generally, cardboard with a basis weight exceeding 250 g / ㎡ and a thickness greater than 0.5 mm is called cardboard. The control of the water content of cardboard plays an important role in the production of cardboard. Usually, the cardboard is placed in a dryer for moisture control. However, the adjustment of the moisture of the cardboard by the dryer can only be adjusted by the drying time and the conveying speed, and real-time monitoring is required. If the moisture of the cardboard is lower than the standard value, the cardboard needs to be taken out of the dryer, sprayed with water on the cardboard, and then placed back in the dryer, which is time-consuming and laborious. Therefore, a cardboard moisture control device is proposed to facilitate the moisture control of cardboard. Content of the Utility Model

[0003] In view of the problems in the prior art, the utility model provides a cardboard moisture control device.

[0004] The technical solution adopted by the utility model to solve its technical problems is a cardboard moisture control device, which includes a box body. One side of the box body is provided with a feed inlet, a motor, two stoppers and two baffles. Inside the box body, there are a slider, a cross bar, a lead screw and a plurality of rollers. The output shaft of the motor is connected to one end of the lead screw through a coupling. Both of the two stoppers and the two baffles are welded to the box body. On the opposite side walls of the two stoppers, first hydraulic cylinders are fixed. On the piston rods of the two first hydraulic cylinders, support plates are fixed. On the opposite side walls of the two support plates, infrared moisture meters are fixed. Between the two baffles, two guide rollers are rotatably connected. The slider is provided with a threaded hole adapted to the lead screw and a through hole adapted to the cross bar. At the bottom end of the slider, a second hydraulic cylinder is fixed. On the piston rod of the second hydraulic cylinder, a push plate is fixed. All the plurality of rollers are rotatably connected to the box body. Below the lead screw, there is a conduit, and a plurality of nozzles are fixed on the conduit. Below the box body, there are a water tank and a hot air blower. At the top end of the water tank, a water pump is fixed. On the water inlet pipe of the water pump, an elbow is fixed, and the elbow extends into the water tank. On the drain pipe of the water pump, a first valve is fixed. The first valve is threadedly connected with a telescopic pipe. One end of the telescopic pipe away from the first valve is connected to the conduit. A second valve is fixed on the telescopic pipe. One end of the second valve away from the telescopic pipe is fixed with a connecting pipe. One end of the connecting pipe away from the second valve is connected to the exhaust duct of the hot air blower.

[0005] By adopting the above technical solution, the cardboard is placed on the guide roller, and the piston rods of the two first hydraulic cylinders drive the two support plates to move towards the cardboard, facilitating the adjustment of the distance between the two infrared moisture meters. The infrared moisture meters detect the moisture content of the cardboard. When the moisture content of the cardboard exceeds the standard value, the hot air blower is turned on, the second valve is opened, the first valve is closed, and the cardboard is pushed into the box. The piston rod of the second hydraulic cylinder drives the push plate to move downward, and the output shaft of the motor drives the lead screw to rotate. The slider, the second hydraulic cylinder and the push plate move horizontally, facilitating the pushing of the cardboard to move. The hot air is ejected from the nozzle, which is conducive to the evaporation of the moisture in the cardboard. When the moisture content is lower than the standard value, the second valve is closed, the first valve and the water pump are opened, the water pump extracts the water in the water tank, and the water is sprayed onto the cardboard from the nozzle, realizing the regulation of the moisture content of the cardboard, saving time and effort.

[0006] Specifically, a drain valve is fixed on one side of the box away from the motor.

[0007] By adopting the above technical solution, opening the drain valve facilitates the discharge of the excess water in the box.

[0008] Specifically, an inclined guide plate is fixed inside the box, and the guide plate is located below the plurality of roller shafts.

[0009] By adopting the above technical solution, the arrangement of the guide plate is conducive to the collection and discharge of water.

[0010] Specifically, a maintenance opening is provided on one side of the box, a glass door is provided in the maintenance opening, and one side of the glass door is connected to the box through a hinge.

[0011] By adopting the above technical solution, through the maintenance opening and the glass door, it is convenient to observe the internal situation of the box.

[0012] Specifically, the end of the lead screw away from the motor is rotatably connected to the box.

[0014] (1) For the cardboard moisture regulation device of the present utility model, the cardboard is placed on the guide roller, and the piston rods of the two first hydraulic cylinders drive the two support plates to move towards the cardboard, facilitating the adjustment of the distance between the two infrared moisture meters. The infrared moisture meters detect the moisture content of the cardboard. When the moisture content of the cardboard exceeds the standard value, the hot air blower is turned on, the second valve is opened, the first valve is closed, and the cardboard is pushed into the box. The piston rod of the second hydraulic cylinder drives the push plate to move downward, and the output shaft of the motor drives the lead screw to rotate. The slider, the second hydraulic cylinder and the push plate move horizontally, facilitating the pushing of the cardboard to move. The hot air is ejected from the nozzle, which is conducive to the evaporation of the moisture in the cardboard.
