Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cardboard processing devices, and specifically relates to a cardboard processing device for preventing warping of edges. Background Technique
[0002] When processing cardboard, due to the unevenness of moisture on the surface of the cardboard or the extrusion by rollers during processing, warping of the two sides of the cardboard occurs. This warping will cause a poor rate in cardboard processing during subsequent processing, affecting the final finished product. Currently, the equipment for preventing such phenomena generally flattens the warping by extrusion, but this method can only slightly reduce the height of the warping and cannot effectively flatten the warping.
[0003] In order to solve the above technical problems, Chinese Patent CN116604889B, a cardboard high-pressure composite device for corrugated cardboard processing, points out that through the extrusion of an auxiliary pressing mechanism, specifically, the driving motor three drives and controls the rotation of the rotating shaft rod between the second bearings, so that the driving gear disc meshes and drives the inner and outer activities of the driving plate to adjust, through the activities of the second support and the second support plate, through the support of the first support and the first support plate for activities, and through the connecting frame and the connecting rod to control the downward flipping adjustment of the first baffle and the second baffle. The first baffle and the second baffle with an arc-shaped structure surface can assist in feeding and edge pressing of the corrugated cardboard to avoid warping. Although the above patent can indeed solve the problem, there are still certain deficiencies. This patent prevents warping as a whole, but the warping on both sides cannot be effectively extruded in a mobile manner, so that the prestress cannot be effectively changed, and thus the warping cannot be effectively flattened.
[0004] Therefore, in order to be able to apply pressure to the cardboard surface in a mobile manner, change the prestress of the cardboard, and thus improve the efficiency of the device in preventing cardboard warping, a cardboard processing device for preventing warping is hereby proposed to solve the technical problems existing in the above-mentioned prior art.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A cardboard processing device for preventing warping includes a device chassis, a conveying mechanism, an auxiliary conveying mechanism, and a heating structure.

A deceleration servo motor is installed at the right end face of the mounting plate. The output end of the deceleration servo motor is connected to a group of upper conveying rollers.
[0009] As a preferred technical solution, the conveying mechanism includes an upper mounting frame, a first servo motor, a first gear, a lower conveying roller, and a first toothed chain. The upper mounting frame is installed on the device chassis. The inner side of the upper mounting frame is equidistantly distributed with lower conveying rollers.

[0011] As a preferred technical solution, the heating structure includes a heating box and a fan. The heating box is installed on the upper end face of the mounting plate. A fan is installed at the upper end of the heating box.
[0012] Compared with the prior art, the present utility model provides a cardboard processing device for preventing warping, which has the following beneficial effects:
[0013] 1. This device mainly drives the upper conveyor roller to rotate through a deceleration servo motor, and then drives the pressure block to rotate. At this time, the second servo motor drives the reciprocating lead screw to rotate, and through the action of the threaded bushing, it drives the pressure block to move reciprocally on the cylindrical surface. Therefore, through the mutual extrusion of the lower conveyor roller, the prestress on the side edge of the cardboard is changed. Furthermore, through the cooperation of the heating structure, the quality and efficiency of improving the warping are further improved, thus solving the problem that the existing cardboard processing device for preventing warping cannot effectively change the prestress generated by the warping of the cardboard, and thus reducing the efficiency of improving the warping of the cardboard.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0026] Embodiment
[0027] Please refer to Figure 1-10 , the present invention provides the following technical solutions: A cardboard processing device for preventing warping includes a device chassis, a conveying mechanism, an auxiliary conveying mechanism, and a heating structure. A reciprocating pressing structure is installed on the auxiliary conveying mechanism. The reciprocating pressing structure includes a second servo motor 10, a cylinder 14, a pressing block 15, a reciprocating lead screw 18, a third gear 19, a third tooth chain 20, and a threaded bushing 21. The auxiliary conveying mechanism includes a mounting plate 8, a reducing servo motor 9, and an upper conveyor roller 11. Cylinders 14 are symmetrically arranged on the surface of the upper conveyor roller 11. The inside of the cylinder 14 is hollow and an opening is provided on the surface. A reciprocating lead screw 18 is horizontally inserted into the opening. A second servo motor 10 is installed at the left end of the mounting plate 8. The output end of the second servo motor 10 is connected to the reciprocating lead screw 18. A threaded bushing 21 is provided on the inner side surface of the pressing block 15. The threaded bushing 21 is connected to the reciprocating lead screw 18, and the pressing block 15 passes through the opening and is located on the outer surface of the cylinder 14 and reciprocates along the surface of the cylinder 14. In order to prevent the surface of the pressing block 15 from squeezing the side end of the cardboard and causing stacking of the cardboard, the surface of the pressing block 15 is polished and the outer end is rounded. The middle surface of the reciprocating lead screw 18 is a smooth surface. A third gear 19 is installed at the right end of the reciprocating lead screw 18. The third tooth chains 20 are connected between the groups of third gears 19.
[0028] In this implementation scheme, the specific working principle is as follows: Through this device, the deceleration servo motor 9 drives the upper conveying roller 11 to rotate. When rotating, it also drives the pressing block 15 to rotate. At this time, the second servo motor 10 is started to drive the reciprocating lead screw 18 to rotate. It should be noted that the reciprocating lead screw 18 is horizontally inserted inside the upper conveying roller 11, and the surface of the reciprocating lead screw 18 does not contact the inner surface of the upper conveying roller 11. Therefore, through the action of the reciprocating lead screw 18, the pressing block 15 is driven to move reciprocally along the cylindrical surface, and then the cooperation with the lower conveying roller can better eliminate the prestress on the side surface of the cardboard, thereby preventing the occurrence of warping. And through the cooperation of the heating structure, it solves the problem that the existing cardboard processing device for preventing warping cannot effectively change the prestress generated by the warping of the cardboard, thereby reducing the efficiency of improving the warping of the cardboard.
[0029] According to the above, in order to prevent the pressing block 15 from colliding with the cardboard or failing to contact the surface of the cardboard, specific reference can be made to Figure 3 It can be seen that the diameter of the pressing block 15 is the same as that of the upper conveying roller 11.

The output end of the first servo motor 4 is connected to a first gear 5. Gears are installed on the right end surfaces of the lower conveying rollers 6. The first gear 5 is connected to the gears by a first chain 7. By driving the first gear 5 to rotate by the first servo motor 4, the first chain 7 is driven to rotate, thereby realizing the rotation of the lower conveying roller 6, and cooperating with the upper conveying roller 11 to realize the conveyance of the cardboard.
[0032] Among them, for the specific device chassis, specific reference can be made to Figure 1 And [[ID=It can be seen that the device chassis includes support legs 1 and a bottom mounting frame 3; the bottom mounting frame 3 is installed inside the support legs 1, a first servo motor 4 is installed on the upper end surface of the bottom mounting frame 3, and its upper mounting frame 2 is installed at the upper end of the support legs 1.
