It has high mechanical strength and can withstand collisions and falls during transportation. When corrugated base paper is formed, it must be preheated to evaporate the excess moisture in the base paper, adjust the moisture of the base paper in the entire width direction, and ensure the temperature required for the base paper to be formed.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1 - Figure 3 A corrugated base paper preheating machine with a paper roll tension adjustment mechanism in this embodiment includes a base 1, and a first mounting plate 2, a second mounting plate 4 and a third mounting plate 9 are sequentially arranged on the upper surface of the base 1. A smoothing roller 3 is rotatably installed inside the first mounting plate 2, a tensioning mechanism is arranged inside the second mounting plate 4 for adjusting the tension of the paper roll, and a preheating mechanism is arranged inside the third mounting plate 9 for preheating the corrugated base paper and adjusting the preheating area.

[0025] Please combine Figure 2 and Figure 3 The preheating mechanism includes a fixed shaft 10 fixedly installed inside the third mounting plate 9, a preheating tube 11 is fixedly installed on the surface of the fixed shaft 10, and a gear 15 is rotatably installed at one end of the fixed shaft 10, a limiting plate 16 is fixedly connected to the side of the preheating tube 11 close to the gear 15, a button 17 corresponding to the gear 15 is penetrated inside the limiting plate 16, a return spring 18 is penetrated on the top of the button 17, a column 19 is fixedly connected to the bottom of the gear 15, and an adjusting roller 20 is rotatably installed inside the column 19.

[0026] The adjusting roller 20 is driven to rotate by the rotation of the gear 15, so as to adjust the contact area between the base paper and the preheating tube 11. The structure is simple and easy to operate.

[0027] Please combine Figure 2 A positioning roller 12 is slidably connected to the top of the third mounting plate 9, and one end of the positioning roller 12 passes through the third mounting plate 9. A threaded rod 14 is threadedly connected to the top of the third mounting plate 9. The positioning roller 12 is fixedly connected to a fixing block 13, and the bottom of the threaded rod 14 is fixedly connected to the upper surface of the fixing block 13.

[0028] The distance between the positioning roller 12 and the preheating tube 11 is adjusted by rotating the threaded rod 14 to facilitate the use of corrugated paper of different thicknesses. The positioning roller 12 is used to press the base paper to prevent it from deflecting during the winding process.

[0029] Please combine Figure 1 The tensioning mechanism includes a support plate 5 sliding on the top of the second mounting plate 4, both ends of the support plate 5 are fixedly connected with fixed plates 6, a tensioning roller 7 is rotatably installed inside the fixed plate 6, and the bottom of the support plate 5 is fixedly connected with the output end of the cylinder 8.

[0030] The tension roller 7 is driven up and down by the cylinder 8 to adjust the tension of the base paper to prevent wrinkles and improve product quality.

[0031] Please combine Figure 2 A rotating disk corresponding to the gear 15 is provided at one end of the fixed shaft 10 away from the gear 15 .

[0032] Please combine Figure 2 The adjusting roller 20 is arranged corresponding to the preheating tube 11, and the adjusting roller 20 rotates around the preheating tube 11.

[0033] The implementation principle of a corrugated base paper preheating machine with a paper roll tension adjustment mechanism in the embodiment of the present application is as follows: when working, the base paper roll is brought into contact with the upper surface of the smoothing roller 3, and then into contact with the lower surface of the tensioning roller 7, and then pressed on the upper surface of the preheating tube 11 through the positioning roller 12, and finally rolled up after passing through the adjusting roller 20. The support plate 5 can be driven downward by the cylinder 8, so that the tensioning roller 7 moves downward to tension the base paper, and the positioning roller 12 can be driven up and down by rotating the threaded rod 14, so as to facilitate the use of corrugated paper of different thicknesses. When it is necessary to change the contact area between the base paper and the preheating tube 11, the button 17 is lifted up so that the button 17 is disengaged from the gear 15. At this time, the gear 15 is rotated, thereby driving the adjusting roller 20 to rotate around the preheating tube 11, thereby changing the angle between the adjusting roller 20 and the preheating tube 11, and then changing the contact area between the base paper and the preheating tube 11.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
