[0002] Corrugated paper is a plate-like material made by gluing noodle paper and corrugated paper formed by corrugating rollers. When processing single-sided corrugated board, the corrugated base paper needs to be rolled by corrugating rollers to form corrugations, and then bonded with single-sided paper sheets to form single-sided corrugated board. Before rolling by corrugating rollers, a preheating device needs to be used to dry and preheat the corrugated base paper to make it easier to form and bond.

[0003] At present, in the existing technology, a heating component is provided inside the machine, a group of guide rollers are installed outside the heating component, and the corrugated paper is passed through the guide rollers and fits with the heating component to complete the preheating work, and the temperature and surface humidity of the base paper are adjusted to ensure that the base paper has good adhesion. This operation is convenient and fast, but the distance between the guide rollers and the heating component in the corrugated paper preheater is fixed, and it cannot be used for preheating corrugated paper of different thicknesses.

[0004] Therefore, it is particularly important to improve the existing corrugated paper preheating device and design a new corrugated paper preheating device to solve the above technical defects and improve the practicability of the overall corrugated paper preheating device. Utility Model Content

[0010] As a preferred solution of the utility model, a through slot is provided on the top of the dust cover, and the tooth plate extends to the outside of the dust cover through the through slot.

[0011] As a preferred solution of the utility model, a sliding column is installed at the bottom end of the tooth plate away from one side, a sliding groove is opened at a position corresponding to the sliding column on the inner side wall of the machine body, and the guide roller is connected to the machine body through the sliding column.

[0012] As a preferred solution of the utility model, a tension roller is installed between the tooth plates and above the guide roller, a groove is opened inside the tooth plates, and both ends of the tension roller extend into the inside of the groove.

[0013] As a preferred solution of the utility model, a spring is installed inside the groove, a limiting ring is installed at the bottom of the spring, and an anti-collision block is installed at the bottom end of the inner side of the groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] In the utility model, the output end of the driving motor is connected to one end of the linkage shaft to drive the gear to rotate, thereby realizing meshing movement between the gear and the tooth plate, so that the tooth plate slides on the slide rail, drives the slide column to move inside the slide groove, and drives the guide roller to extrude in the direction of the steam roller, so that corrugated paper of different thicknesses can control the distance between it and the steam roller.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] The corrugated paper preheating device in the corrugated paperboard production line comprises a machine body 1, a paper receiving roller 2 is installed at the front end of the machine body 1, a paper winding roller 3 is installed at the rear end of the machine body 1, a dust cover 4 is installed in the middle of the machine body 1, a steam roller 5 is installed inside the dust cover 4, and an adjustment component 6 is installed above the steam roller 5;

[0026] The adjusting component 6 is used to control the distance between the corrugated paper with different thicknesses and the steam roller 5 .

[0027] For further information, see Figure 1 and Figure 3In this embodiment, the adjustment component 6 includes a linkage shaft 601, a gear 602, a toothed plate 603, a slide rail 604 and a guide roller 605. The linkage shaft 601 is installed inside the dust cover 4, the gear 602 is installed at the left and right ends of the linkage shaft 601, the toothed plate 603 is installed outside the gear 602, the slide rail 604 is installed outside the toothed plate 603, and the guide roller 605 is installed at the bottom end of the toothed plate 603. When the corrugated paper needs to be preheated, the corrugated paper is placed outside the paper winding roller 3, and one end of the corrugated paper is passed between the guide roller 605 and the tension roller 608, and then it is passed around the bottom of the steam roller 5. , and finally wind it around the outside of the paper receiving roller 2. By connecting the motor to one end of the paper receiving roller 2, the corrugated paper can be transmitted. When the thickness of the corrugated paper is different, in order to prevent the corrugated paper from not being close to the steam roller 5, the output end of the driving motor is connected to one end of the linkage shaft 601, so that the linkage shaft 601 can be rotated, driving the gear 602 to rotate, and the gear 602 and the tooth plate 603 can be meshed. The tooth plate 603 slides on the slide rail 604, and the guide roller 605 is squeezed toward the steam roller 5, so that the distance between corrugated paper of different thicknesses and the steam roller 5 can be controlled.

[0028] Among them, see Figure 1 and Figure 3 In this embodiment, a through slot is provided on the top of the dust cover 4, and the tooth plate 603 extends to the outside of the dust cover 4 through the through slot. The through slot allows the tooth plate 603 to move inside the dust cover 4 without any obstructions when the tooth plate 603 is lifted or lowered, and the dust cover 4 effectively prevents the friction between the corrugated paper and the guide roller 605, thereby preventing waste paper scraps from splashing to the outside.

[0029] Furthermore, please see Figure 1 and Figure 2 In this embodiment, a slide column 606 is installed at the bottom end of the tooth plate 603 away from the side, and a slide groove 607 is opened at a position corresponding to the slide column 606 on the inner wall of the machine body 1. The guide roller 605 is connected to the machine body 1 through the slide column 606. When the tooth plate 603 moves up or down, the slide column 606 moves inside the slide groove 607. Since the slide groove 607 is designed to be vertical, the slide column 606 can only move linearly, thereby ensuring the stability of the tooth plate 603 during movement.

[0030] Furthermore, please see Figure 1 , Figure 2 and Figure 3In this embodiment, a tension roller 608 is installed between the tooth plates 603 and above the guide roller 605. A groove 609 is opened inside the tooth plate 603. Both ends of the tension roller 608 extend to the inside of the groove 609. Through the design of the tension roller 608, a closed space is formed between the tension roller 608 and the guide roller 605, which effectively ensures that the corrugated paper will not be offset when moving.

[0031] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, a spring 610 is installed inside the groove 609, a limit ring 611 is installed at the bottom of the spring 610, an anti-collision block is installed at the bottom end of the inner side of the groove 609, a rotating ring 612 is installed inside the limit ring 611, a clamping groove is opened outside the rotating ring 612, a ball 613 is installed inside the clamping groove, a fixed sleeve 614 is installed inside the rotating ring 612, and the tension roller 608 is connected to the limit ring 611 through the fixed sleeve 614. When the thickness of the corrugated paper is different, the tension roller 608 is always squeezed and moved in the direction of the guide roller 605 through the expansion and contraction energy storage of the spring 610, which is adapted to different corrugated paper thicknesses. When the corrugated paper moves, it will drive the tension roller 608 to rotate, thereby driving the fixed sleeve 614 to rotate. At the same time, the fixed sleeve 614 drives the rotating ring 612 to rotate inside the limit ring 611, and the design of the ball 613 does not affect the fixation of the limit ring 611 when the rotating ring 612 rotates.

[0032] In this embodiment, the implementation scenario is specifically as follows: when the corrugated paper needs to be preheated, the corrugated paper is placed on the outside of the paper winding roller 3, and then one end of the corrugated paper is passed through the guide roller 605 and the tension roller 608, and then it is passed around the bottom of the steam roller 5, and finally it is wound around the outside of the paper receiving roller 2, and the motor is connected to one end of the paper receiving roller 2 to realize the transmission movement of the corrugated paper. When the thickness of the corrugated paper is different, in order to avoid the corrugated paper not being close to the steam roller 5, the output end of the driving motor is connected to one end of the linkage shaft 601, so that the linkage shaft 601 is rotated, and the gear 602 is driven to rotate, so that the gear 602 and the tooth plate 603 are meshed, so that the tooth plate 603 slides on the slide rail 604, and the slide column 606 moves inside the slide groove 607. Since the slide groove 607 is designed to be vertical, the slide column 606 only needs to move. It can make linear motion to ensure the stability of the tooth plate 603 during movement, drive the guide roller 605 to squeeze in the direction of the steam roller 5, and realize that the distance between corrugated paper of different thicknesses and the steam roller 5 can be controlled. Through the design of the tension roller 608, a closed space is formed between the tension roller 608 and the guide roller 605, which effectively ensures that the corrugated paper will not deviate during movement. When the thickness of the corrugated paper is different, the tension roller 608 is always squeezed in the direction of the guide roller 605 through the expansion and contraction energy storage of the spring 610, which is adapted to different corrugated paper thicknesses. When the corrugated paper moves, it will drive the tension roller 608 to rotate, thereby driving the fixed sleeve 614 to rotate. At the same time, the fixed sleeve 614 drives the rotating ring 612 to rotate inside the limiting ring 611, and through the design of the ball 613, when the rotating ring 612 rotates, it does not affect the fixation of the limiting ring 611.
