[0002] Cardboard is a multi-purpose material that is tough, lightweight, and environmentally friendly. Cardboard applications usually include packaging, construction, advertising, and pharmaceutical packaging.

[0003] Since the process of cardboard is to use adhesives and other bonding materials, it will contain a certain amount of moisture in the process of being manufactured into semi-finished products, which seriously leads to a decrease in the compressive strength of the cardboard. Therefore, the semi-finished cardboard needs to be dried during the production process to ensure that the cardboard is within a certain dry range.

[0004] In the process of drying semi-finished cardboard, the existing cardboard drying device uses multiple hot air blowers for blowing and drying in order to improve the drying efficiency of the semi-finished cardboard. This method not only increases the use cost of the hot air blower, but also is not uniform during the process of blowing and drying the cardboard, resulting in uneven heating and drying of the cardboard. Therefore, it is necessary to provide a cardboard drying device with uniform heating to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a cardboard drying device with uniform heating, so as to solve the problems raised in the above-mentioned background technology that when drying cardboard, on the one hand, the use cost of the hot air blower is increased, and on the other hand, it is difficult to heat and dry the cardboard more uniformly. The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a uniformly heated cardboard drying device, comprising a base, a conveying assembly and a cardboard body, wherein the conveying assembly is installed on the inner side of the base through a support, and the cardboard body is placed above the conveying assembly, and the conveying assembly is installed on the inner side of the base through a support, and the cardboard body is placed above the conveying assembly;

[0010] In a further embodiment, every two groups of the limit plates are equidistantly distributed on the inner side of the base, and the number of the limit plates is in a one-to-one correspondence with the number of the adjustment mechanisms.

[0011] In a further embodiment, the adjustment mechanism includes a screw rod with a bearing installed on the inner wall of the base, a slider is threadedly connected to the outer side of the screw rod, and a connecting rod is installed on one side of the slider, a movable roller is movably connected between the two connecting rods, and a sprocket mechanism is keyed to the outer side of the screw rod.

[0012] In a further embodiment, a slide groove is provided on one side below the fan housing, and an air outlet is connected to the lower right side of the fan housing.

[0013] In a further embodiment, the drying mechanism includes a telescopic sleeve installed on the inner side of the base, and a spring is clamped on the outer side of the telescopic sleeve, the end of the telescopic sleeve is connected to a linkage plate, and a piston valve plate is installed on one side of the linkage plate, and the hot air blower is installed on the inner side of the fan casing.

[0014] In a further embodiment, the piston valve plate and the interior of the air outlet form a sealed lifting structure, and the upper part of the piston valve plate is inclined.

[0025] The limiting plates 4 are installed on the inner side of the base 1, and an adjustment mechanism 5 is provided between each group of limiting plates 4 for adjusting and correcting paperboards of different widths;

[0026] The fan casing 6 is installed on the upper inner side of the base 1, and a drying mechanism 7 for uniformly heating and drying the paperboard is arranged on the inner side of the fan casing 6.

[0027] Example 1: Please refer to Figure 1-2 and Figure 4, every two groups of limit plates 4 are equidistantly distributed on the inner side of the base 1, and the number of limit plates 4 corresponds to the number of adjustment mechanisms 5 in a one-to-one relationship. The adjustment mechanism 5 includes a screw rod 501 with a bearing mounted on the inner wall of the base 1, a slider 502 is threadedly connected to the outer side of the screw rod 501, and a connecting rod 503 is installed on one side of the slider 502, a movable roller 504 is movably connected between the two connecting rods 503, and a sprocket mechanism 505 is keyed to the outer side of the screw rod 501;

[0028] The width between the adjustment mechanisms 5 is adjusted according to the width of the cardboard. The specific adjustment method is as follows: insert the cardboard to be dried from the right side of the conveying component 2 to a certain size, and then manually rotate the two rockers respectively, so as to cooperate with the sprocket mechanism 505 to drive all the screw rods 501 to rotate, so that the screw rods 501 can effectively drive the corresponding sliders 502, connecting rods 503 and movable rollers 504 to move inward at the same time until the outer surfaces of the movable rollers 504 contact the end surfaces on both sides of the cardboard body 3. Note that the two movable rollers 504 do not need to clamp the cardboard body 3. The setting of this structure can not only correct the cardboard body 3 to be parallel to the horizontal direction of the conveying component 2, but also prevent the drying mechanism 7 from causing an angle deviation when blowing air to the upper surface of the cardboard body 3 for drying, that is, causing uneven heating.

[0029] Example 2: Please refer to Figure 1-3 , which is different from Example 1 in that: a slide groove 601 is provided on one side below the fan casing 6, and an air outlet 602 is connected to the lower right side of the fan casing 6, the drying mechanism 7 comprises a telescopic sleeve 701 installed on the inner side of the base 1, and a spring 702 is clamped on the outer side of the telescopic sleeve 701, a linkage plate 703 is connected to the end of the telescopic sleeve 701, and a piston valve plate 704 is installed on one side of the linkage plate 703, and a hot air blower 705 is installed on the inner side of the fan casing 6, the piston valve plate 704 and the inside of the air outlet 602 form a sealed lifting structure, and the upper part of the piston valve plate 704 is inclined;

[0030] After the adjustment mechanism 5 is adjusted, the servo motor drives the shaft to drive the conveying assembly 2 to rotate, and the conveying assembly 2 can convey the calibrated cardboard body 3 to the left. At the same time, the hot air blower 705 inside the drying mechanism 7 is started, so that the hot air blower 705 generates hot air when working and accumulates inside the cavity of the fan housing 6. When the hot air inside the fan housing 6 accumulates more and more, air pressure is generated, and the telescopic sleeve 701 is squeezed to extend downward in cooperation with the spring 702. When the telescopic sleeve 701 extends downward, the linkage plate 7 is driven 03 and the piston valve plate 704 connected to the right end cooperate with the slide groove 601 to move downward. The downward movement of the piston valve plate 704 can open the air outlet 602. At this time, the hot air will be evenly blown from the air outlet 602 to the top of the cardboard body 3. This drying method only requires one hot air blower 705, thereby saving the use cost of the hot air blower 705, and the warm air in the fan housing 6 can be blown out more evenly to the top of the cardboard body 3 through the air outlet 602 through the drying mechanism 7, thereby improving the uniformity of drying the cardboard body 3.

[0031] Working principle: Figure 1-4 As shown, the width between the adjustment mechanisms 5 is adjusted according to the width of the paperboard, and the specific adjustment method is as follows:

[0032] Insert the cardboard to be dried from the right side of the conveying component 2 to a certain size, and then manually rotate the two rockers respectively, so that the sprocket mechanism 505 can cooperate with all the screw rods 501 to rotate, so that the screw rods 501 can effectively drive the corresponding sliders 502, connecting rods 503 and movable rollers 504 to move inward at the same time until the outer surface of the movable rollers 504 contacts the end surfaces of both sides of the cardboard body 3. Note that the two movable rollers 504 do not need to clamp the cardboard body 3. The setting of this structure can not only correct the cardboard body 3 to be parallel to the horizontal direction of the conveying component 2, but also prevent the drying mechanism 7 from causing an angle deviation when blowing air to the upper surface of the cardboard body 3 to dry, that is, causing uneven heating.

[0033] After the adjustment mechanism 5 is adjusted, the servo motor drives the shaft to drive the conveying assembly 2 to rotate, and the conveying assembly 2 can convey the calibrated cardboard body 3 to the left. At the same time, the hot air blower 705 inside the drying mechanism 7 is started, so that the hot air blower 705 generates hot air when working and accumulates inside the cavity of the fan housing 6. When the hot air inside the fan housing 6 accumulates more and more, air pressure is generated, and the telescopic sleeve 701 is squeezed to extend downward in cooperation with the spring 702. When the telescopic sleeve 701 extends downward, the linkage plate 7 is driven 03 and the piston valve plate 704 connected to the right end cooperate with the slide groove 601 to move downward. The downward movement of the piston valve plate 704 can open the air outlet 602. At this time, the hot air will be evenly blown from the air outlet 602 to the top of the cardboard body 3. This drying method only requires one hot air blower 705, thereby saving the use cost of the hot air blower 705, and the warm air in the fan housing 6 can be blown out more evenly to the top of the cardboard body 3 through the air outlet 602 through the drying mechanism 7, thereby improving the uniformity of drying the cardboard body 3.
