[0029] The vacuum moisture content regulating device based on incoming material difference provided by the utility model embodiment can make the water amount flowing into the vacuum moisture content box positively correlated with the weight of the material transported on the incoming material conveying belt, thereby better achieving automatic adjustment of the water amount of vacuum moisture content according to the difference of incoming material, while the device can save manual adjustment, and the labor intensity of workers is reduced.

[0030] Further, linear bearings 15 are arranged in the two perforations, so that the left top rod 4 and the right top rod 5 can smoothly ascend and descend in the vertical direction.

[0031] Preferably, the bottom end of the left top rod 4 and the right top rod 5 has an inverted U-shaped frame, and the pin shaft is arranged between the two side plates of the inverted U-shaped frame, and the left and right ends of the lever are located in the openings of the two inverted U-shaped frames, respectively.

[0032] Specifically, the left and right ends of the lever 3 are both provided with a slot hole 16 for the pin shaft to pass through, and the slot hole 16 is an elongated hole extending in the left-right direction, so that the pin shaft can smoothly rotate and move in the slot hole, avoiding interference and facilitating force transmission.

[0033] Preferably, the left top rod 4 and the right top rod 5 are both two-section structures, the upper section and the lower section are threadedly connected through a double-end reverse screw pipe 17, and the double-end reverse screw pipe 17 is located above the device base plate. When the water inlet amount of the vacuum moisture conditioning box needs to be finely adjusted, the length of the left top rod 4 and the right top rod 5 can be adjusted by rotating the double-end reverse screw pipe 17 to drive the upper section and the lower section to move close to or away from each other, so that the dislocation degree between the valve hole 13 and the water inlet pipe 10 and the water outlet pipe 11 can be flexibly adjusted according to the type and moisture content of the incoming material, thereby realizing manual fine adjustment of the water inlet amount.

[0034] Specifically, a telescopic guide rod 18 is arranged between the bottom surface of the roller frame 6 and the top surface of the left end of the device base plate 1.

[0039] The device substrate 1 is arranged below the incoming material conveying belt, and the supporting roller 7 supports the bottom surface of the incoming material conveying belt; the material transported on the incoming material conveying belt will make the incoming material conveying belt sink, at this time, the supporting roller 7 supported on the bottom surface of the incoming material conveying belt will move downward under the pressure of the conveyed material, thereby the left end of the lever 3 is pressed downward by the left jacking rod 4, the right end of the lever 3 moves upward, the right jacking rod 5 drives the valve core 12 to move upward, thereby the valve hole 13 moves to between the water inlet pipe 10 and the water outlet pipe 11, at this time, the water flow introduced by the water inlet pipe 10 flows to the water outlet pipe 11 through the valve hole 13, and then flows into the vacuum moisture conditioning box;

[0040] When the material transported on the incoming material conveying belt is more and heavier, the sinking amplitude of the incoming material conveying belt increases, at this time, the sinking amplitude of the left jacking rod 4 and the upward moving amplitude of the right jacking rod 5 and the valve core 12 increase, thereby the area of the valve hole 13 and the water inlet pipe 10 and the water outlet pipe 11 intersects, that is, the area of the flow cross section increases, at this time, the water flow flowing into the vacuum moisture conditioning box also increases correspondingly;

[0041] When the material transported on the incoming material conveying belt is less and lighter, the sinking amplitude of the incoming material conveying belt decreases, at this time, the sinking amplitude of the left jacking rod 4 and the upward moving amplitude of the right jacking rod 5 and the valve core 12 decrease, thereby the area of the valve hole 13 and the water inlet pipe 10 and the water outlet pipe 11 intersects decreases, thereby the water flow flowing into the vacuum moisture conditioning box, that is, the water adding amount also decreases correspondingly.

[0042] It can be seen that the water adding amount flowing into the vacuum moisture conditioning box is proportional to the weight and quantity of the material transported on the incoming material conveying belt, and the water adding amount of the vacuum moisture conditioning is automatically adjusted according to the incoming material difference.

[0043] Although some specific embodiments of the present application have been described in detail by examples, those skilled in the art should understand that the above examples are only for illustration, and are not intended to limit the scope of the present application.
