[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of wavy core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself. It is mainly made of local straw pulp and waste paper through pulping to make raw cardboard similar to yellow cardboard, which is then mechanically processed and rolled into a corrugated shape, and then bonded to the boxboard with adhesives such as sodium silicate on its surface.

Folding and placing the corrugated cardboard will cause the corrugated cardboard to be damaged. When the size of the corrugated cardboard is small, the corrugated cardboard cannot be located at the center of the mechanism during use, and the drying and leveling effect is not good. Based on this, the utility model designs a corrugated cardboard drying and leveling mechanism to solve the above problems. Utility Model Content

[0026] A drying mechanism is installed in the inner cavity of the working frame 2, and a lifting mechanism is installed on the top of the inner cavity of the working frame 2 for changing the distance between the drying mechanism and the corrugated cardboard.

[0027] The outer ring of the threaded rod 5 is sleeved with a crank 7 and the threaded rod 5 is rotatably connected to the adjustment plate 6 through a bearing. A limit rod 8 with a telescopic function is installed between the adjustment plate 6 and the fixed plate 3, and a baffle 9 is fixedly connected to one side of the adjustment plate 6.

[0028] In the embodiment of the utility model, when the size of the corrugated cardboard does not match the size of the adjustment plate 6, the crank 7 is rotated to drive the threaded rod 5 to rotate in the inner cavity of the threaded hole 4, thereby driving the adjustment plate 6 connected to the bearing to move, and the angle of rotation of the crank 7 and the threaded rod 5 is controlled according to the size of the corrugated cardboard, thereby controlling the distance of movement of the adjustment plate 6, so that the adjustment plate 6 is located at the edge of the corrugated cardboard, which is convenient for limiting the position of corrugated cardboards of different sizes. The existence of the limit rod 8 can limit the moving direction of the adjustment plate 6 and improve the stability of the use of the adjustment plate 6.

[0029] Please refer to Figure 1-5 In the embodiment of the utility model, an electric heating component 10 is installed on one side of the working frame 2, and an electric heating tube 11 is installed in the inner cavity of the working frame 2 and is electrically connected to the electric heating component 10, and the electric heating tube 11 is distributed in multiple groups of linear arrays.

[0030] The lifting assembly includes a hydraulic telescopic rod 12, a lifting plate 13 is installed at the bottom of the output shaft of the hydraulic telescopic rod 12, a slide groove 14 is opened on the inner wall of the working frame 2, and the front and back sides of the lifting plate 13 are fixedly connected with sliders 15, and the sliders 15 are slidably connected in the inner cavity of the slide groove 14. The drying assembly includes a fan 16, and the top of the fan 16 is fixedly connected to the bottom of the lifting plate 13. The drying assembly also includes a dryer 17, and the dryer 17 is installed on the inner wall of the working frame 2.

[0031] A limit plate 18 is installed at the bottom of the lifting plate 13, and a pin shaft 19 is rotatably connected between the limit plates 18. The outer ring of the pin shaft 19 is fitted with a leveling roller 20. There are two groups of leveling rollers 20 and they are respectively located on both sides of the bottom of the lifting plate 13. The leveling rollers 20 can be raised and lowered in the inner cavity of the working frame 2 as the lifting plate 13 is raised and lowered.

[0032] Start the hydraulic telescopic rod 12. The extension and retraction of the hydraulic telescopic rod 12 will drive the lifting plate 13 to slide in the inner cavity of the working frame 2, thereby changing the position of the fan 16 in the inner cavity of the working frame 2, and then changing the distance between the fan 16 and the corrugated cardboard on the conveyor belt 1, thereby changing the drying intensity. The outer wall of the lifting plate 13 is fixedly connected with a slider 15, and the slider 15 can slide in the inner cavity of the slide 14, thereby limiting the moving direction of the lifting plate 13. A limit plate 18 is set at the bottom of the lifting plate 13, and a pin 19 and a flattening roller 20 are set between the limit plates 18. The flattening roller 20 can contact the surface of the corrugated cardboard. As the conveyor belt 1 is driven, the flattening roller 20 rotates and flattens the corrugated cardboard. When the lifting plate 13 is lifted or lowered in the inner cavity of the working frame 2, the retractable limiting plate 18 will retract and retract. Under the action of the gravity of the leveling roller 20 and the retractable elastic force of the limiting plate 18, the leveling roller 20 always contacts the surface of the corrugated cardboard to perform the leveling operation.

[0033] When in use, when it is necessary to transport corrugated cardboard, the corrugated cardboard is placed on the left side of the conveyor belt 1, and the corrugated cardboard is transported to the right under the conveyor belt 1. When the corrugated cardboard moves to the right to the adjustment plate 6, the adjustment plate 6 itself is a wedge-shaped structure, so the position of the transported corrugated cardboard will be squeezed to the center of the conveyor belt 1, which is convenient for subsequent drying and leveling operations, and also prevents the corrugated cardboard from interfering with the mechanism due to the excessive size of the corrugated cardboard.

[0034] When the size of the corrugated cardboard does not match the size of the adjustment plate 6, the crank 7 is rotated to drive the threaded rod 5 to rotate in the inner cavity of the threaded hole 4, thereby driving the adjustment plate 6 connected to the bearing to move, and the angle of rotation of the crank 7 and the threaded rod 5 is controlled according to the size of the corrugated cardboard, thereby controlling the moving distance of the adjustment plate 6, so that the adjustment plate 6 is located at the edge of the corrugated cardboard, which is convenient for limiting the position of corrugated cardboards of different sizes. The existence of the limit rod 8 can limit the moving direction of the adjustment plate 6 and improve the stability of the use of the adjustment plate 6.

[0035] After the corrugated cardboard moves to the center of the conveyor belt 1, it continues to move to the right along with the conveyor belt 1 until it moves into the inner cavity of the working frame 2. At this time, the electric heating component 10 is started to drive the temperature of the electric heating pipe 11 to rise, and the working principle of this part is a common electric heating method and belongs to the scope of the prior art. After the temperature of the electric heating pipe 11 rises, the fan 16 is started at this time, driving the hot air to blow downward, forming a structure similar to a drying device, and drying the corrugated cardboard. During the operation of the fan 16, the dryer 17 located on the inner wall of the working frame 2 will also work, drying and heating the corrugated cardboard to improve the drying effect.

[0036] When the drying degree and speed need to be changed, the hydraulic telescopic rod 12 can be controlled to start. The extension and retraction of the hydraulic telescopic rod 12 will drive the lifting plate 13 to slide in the inner cavity of the working frame 2, thereby changing the position of the fan 16 in the inner cavity of the working frame 2, and then changing the distance between the fan 16 and the corrugated cardboard on the conveyor belt 1, thereby changing the drying intensity. The outer wall of the lifting plate 13 is fixedly connected with a slider 15, which can slide in the inner cavity of the slide 14, thereby limiting the moving direction of the lifting plate 13.

[0037] A limit plate 18 is provided at the bottom of the lifting plate 13, and a pin 19 and a leveling roller 20 are provided between the limit plates 18. The leveling roller 20 can contact the surface of the corrugated cardboard. As the conveyor belt 1 is driven, the leveling roller 20 rotates and level the corrugated cardboard. When the lifting plate 13 is lifted and lowered in the inner cavity of the working frame 2, the limit plate 18 with telescopic properties will be extended and retracted. Under the action of the gravity of the leveling roller 20 and the telescopic elastic force of the limit plate 18, the leveling roller 20 always contacts the surface of the corrugated cardboard to perform the leveling operation.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit thereof, and that the scope of the present invention is defined by the appended claims and their equivalents.
