[0002] In the prior art, in order to produce thicker smoke and ash during the burning process, the yellow paper is usually made rougher. This causes the yellow paper to be unable to withstand greater pressure during the production and transportation process, affecting the effect of the guide roller in conveying the yellow paper. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an automatic adjustment mechanism for guide rollers for yellow paper processing, so as to solve the technical problems mentioned in the above background technology.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A guide roller automatic adjustment mechanism for yellow paper processing includes a base, support plates are fixedly connected to the top two sides of the base, an active tensioning member is arranged between the two support plates, and a main conveying roller and an auxiliary conveying roller are arranged at intervals from top to bottom on both sides of the active tensioning member, and a gap is left between the main conveying roller and the auxiliary conveying roller for yellow paper to pass through.

[0006] Furthermore, the active tensioning member includes a connecting frame, a main tensioning roller, a secondary tensioning roller and a counterweight. The inner sides of the two support plates are connected to the connecting frame through a rotating shaft. The main tensioning roller and the secondary tensioning roller are arranged between the two connecting frames. The main tensioning roller and the secondary tensioning roller are respectively arranged on both sides of the connecting frame, and a counterweight is arranged below the main tensioning roller.

[0007] Furthermore, the distance between the rotating shaft and the main tensioning roller is A1, the distance between the rotating shaft and the secondary tensioning roller is A2, and A1 is greater than A2, so that the force arm of the main tensioning roller is greater than the force arm of the secondary tensioning roller.

[0008] Furthermore, the counterweight member is composed of a counterweight roller and a connecting plate. Two connecting plates are provided and are rotatably connected to the corresponding connecting frames respectively.

[0011] In summary, the present invention has at least one of the following beneficial technical effects:

[0012] 1. This automatic guide roller adjustment mechanism for yellow paper processing can automatically tension the yellow paper using gravity through the provision of an active tensioning member. This can effectively prevent the yellow paper from being excessively squeezed, which would cause the rough wood fibers on the surface to be flattened and affect the subsequent burning of the yellow paper.

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] Example:

[0022] Reference Figure 1 - Figure 4 The utility model discloses an automatic adjustment mechanism for guide rollers for yellow paper processing, comprising a base 1, with support plates 2 fixedly connected to both sides of the top of the base 1, an active tensioning member 3 arranged between the two support plates 2, and a main conveying roller 4 and an auxiliary conveying roller 5 arranged at intervals from top to bottom on both sides of the active tensioning member 3, and a gap is reserved between the main conveying roller 4 and the auxiliary conveying roller 5 for yellow paper to pass through.

[0023] In this embodiment, when in use, the yellow paper is first passed through between the main conveying roller 4 and the auxiliary conveying roller 5 on one side of the support plate 2, and then the yellow paper is passed through the active tensioning member 3, and finally the yellow paper is passed through between the main conveying roller 4 and the auxiliary conveying roller 5 on the other side, thereby completing the preparation for conveying the yellow paper.

[0024] Because yellow paper needs to be roughened according to the use requirements during production, in order to avoid the surface of the yellow paper being squeezed and the rough surface being flattened, it is necessary to reduce the tension applied by the guide roller to the yellow paper during the transportation process. Figure 2 It can be found that the use of the gravity of the active tensioning member 3 to automatically tension the yellow paper during transportation can prevent the yellow paper from being crushed by excessive tension during transportation, thereby ensuring that the yellow paper does not become loose during transportation and improving the production quality of the yellow paper.

[0025] In a further preferred embodiment of the present invention, Figure 2 As shown, the active tensioning member 3 includes a connecting frame 31, a main tensioning roller 32, a secondary tensioning roller 33 and a counterweight 34. The inner sides of the two support plates 2 are connected to the connecting frame 31 through a rotating shaft. The main tensioning roller 32 and the secondary tensioning roller 33 are arranged between the two connecting frames 31. The main tensioning roller 32 and the secondary tensioning roller 33 are respectively arranged on both sides of the connecting frame 31, and a counterweight 34 is arranged below the main tensioning roller 32.

[0026] In this embodiment, the main tensioning roller 32 and the auxiliary tensioning roller 33 are provided to tension the yellow paper during the conveying process to prevent the yellow paper from becoming loose. The counterweight 34 provided on the main tensioning roller 32 can make the weight of the connecting frame 31 on the side of the main tensioning roller 32 greater than the weight on the side of the auxiliary tensioning roller 33, so that the connecting frame 31 is tilted under the action of gravity, so that the yellow paper is tensioned by the main tensioning roller 32 and the auxiliary tensioning roller 33, which can effectively prevent the yellow paper from becoming loose and further improve the conveying effect of the yellow paper.

[0027] In a further preferred embodiment of the present invention, Figure 3 As shown, the distance between the rotating shaft and the main tensioning roller 32 is A1, and the distance between the rotating shaft and the secondary tensioning roller 33 is A2. A1 is greater than A2, so that the force arm of the main tensioning roller 32 is greater than the force arm of the secondary tensioning roller 33.

[0028] In this embodiment, the distance between the rotating shaft and the main tensioning roller 32 is A1, the distance between the rotating shaft and the auxiliary tensioning roller 33 is A2, and the Figure 3 It can be found that the length of A1 is greater than the length of A2, which can make the active tensioning member 3 tilt under the influence of gravity in the free state, so that the main tensioning roller 32 and the auxiliary tensioning roller 33 naturally tension the yellow paper under the action of gravity. Combined with the gravity of the counterweight 34, the tensioning effect on the yellow paper can be further enhanced, so that the yellow paper remains taut during the transportation process, thereby improving the transportation efficiency of the yellow paper.

[0029] In a further preferred embodiment of the present invention, Figure 2 As shown, the counterweight member 34 is composed of a counterweight roller 341 and a connecting plate 342. Two connecting plates 342 are provided and are rotatably connected to the corresponding connecting frame 31 respectively. The counterweight roller 341 is detachably connected between the two connecting plates 342. The counterweight roller 341 is located directly below the main tensioning roller 32.

[0030] In this embodiment, by setting up the counterweight roller 341, the gravity of the main tensioning roller 32 can be increased, so that the inclination rate of the connecting frame 31 is higher, so that the main tensioning roller 32 and the auxiliary tensioning roller 33 can better tension the yellow paper and prevent the yellow paper from becoming loose during the transportation process.

[0031] However, since the tensile properties of yellow paper vary depending on its thickness, and due to the special properties of yellow paper, its wood fibers are relatively loose, which makes it easier for the yellow paper to burn, and this will further reduce the tensile properties of the yellow paper. Therefore, when conveying thinner yellow paper, the heavier weight of the tensioning roller 32 will cause the yellow paper to be subjected to greater tension and be pulled apart, affecting the conveying of the yellow paper. Therefore, the counterweight roller 341 and the connecting plate 342 are detachably connected, so that when producing thinner yellow paper, the tension applied to the yellow paper can be reduced, thereby preventing the yellow paper from being pulled apart.

[0032] In a further preferred embodiment of the present invention, Figure 2 As shown, the outer walls of the main tensioning roller 32 and the auxiliary tensioning roller 33 are both covered with a silicone sleeve 6, and the outer wall of the silicone sleeve 6 is provided with convex points for increasing friction.

[0033] In this embodiment, since the wood fibers of the yellow paper are relatively loose, the surface of the yellow paper is easily damaged when it is rubbed. Figure 2It can be found that a silicone sleeve 6 is provided on the main tensioning roller 32 and the auxiliary tensioning roller 33. At the same time, the silicone sleeve 6 is provided with raised points to increase friction, which can change the friction between the yellow paper and the main tensioning roller 32 and the auxiliary tensioning roller 33 during the transportation process from sliding friction to rolling friction with less damage, thereby reducing the damage caused by transportation during the production of yellow paper, thereby further improving the quality of yellow paper.

[0034] In a further preferred embodiment of the present invention, Figure 3 and Figure 4 As shown, the inner side wall of the support plate 2 is fixedly connected to a limit block 7 , and the limit block 7 is arranged below the rotating shaft and close to the side of the main tightening roller 32 .

[0035] In this embodiment, since the force arms of the main tensioning roller 32 and the auxiliary tensioning roller 33 are different, the connecting frame 31 will naturally tilt under the action of gravity, so that the main tensioning roller 32 will be located directly below the auxiliary tensioning roller 33, and the auxiliary tensioning roller 33 will be in a higher position, making it difficult for the yellow paper to pass through the auxiliary tensioning roller 33 during the preparation process of conveying, thereby increasing the difficulty of installing the yellow paper.

[0036] Therefore, observe Figure 3 It can be found that a limit block 7 is provided on the inner wall of the support plate 2, and the limit block 7 is used to provide support for the connecting frame 31 to prevent the connecting frame 31 from being in a vertical state under the action of gravity, so that the auxiliary tensioning roller 33 will not be in a high position, making it easier for the yellow paper to pass through the auxiliary tensioning roller 33, which can effectively reduce the installation difficulty in the yellow paper conveying preparation stage.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
