DETAILED DESCRIPTION

[0046] The utility model will be further explained in connection with the drawings and embodiments:

[0047] The utility model discloses an improved guiding roller set for papermaking equipment, and the technical scheme of the utility model is:

[0048] As Figs. 1-3 shown in the drawings, a guide roller set for papermaking equipment comprises:

[0049] Two supporting assemblies are provided with two first tension shafts 5 between them;

[0050] A second tension shaft 21 is connected with the two supporting assemblies;

[0051] The supporting assembly comprises:

[0052] Two tension assemblies are connected with the supporting assembly, and the two tension assemblies are respectively connected with the two first tension shafts 5;

[0053] An adjusting assembly is connected with the supporting assembly, and the adjusting assembly is connected with the second tension shaft 21, and the adjusting assembly is used to adjust the distance between the second tension shaft 21 and the first tension shaft 5;

[0054] Two transmission assemblies are respectively connected with the two first tension shafts 5, and the two transmission assemblies are connected with the adjusting assembly.

[0055] Through the work of the adjusting assembly, the distance between the second tension shaft 21 and the first tension shaft 5 can be reduced to reduce the tension of the paper;

[0056] In the above process, if the transmission assembly works, the two first tension shafts 5 will separate from each other during the rising process of the second tension shaft 21, thereby reducing the bending angle of the paper and reducing the contact area between the paper and the first tension shaft 5 and the second tension shaft 21, to further reduce the phenomenon of dead lines on the paper.

[0057] Further, the supporting assembly further comprises:

[0058] A cross beam 2 is fixed with a support 1 at both ends;

[0059] A vertical beam 3 is fixed with the cross beam 2.

[0060] Further, the tension assembly comprises:

[0061] A fixed plate 6 is fixed with the cross beam 2;

[0062] A spring 7 is fixed on the fixed plate 6;

[0063] A first connecting seat 4 is slidingly connected with the cross beam 2, and the first connecting seat 4 is fixed with the spring 7, and the first connecting seat 4 is rotationally connected with the first tension shaft 5.

[0064] Through the action of the spring 7, the two first connecting seats 4 are separated from each other, thereby separating the two first tension shafts 5 from each other, so that the cloth is kept in a tension state.

[0065] Further, the adjusting assembly comprises:

[0066] a support plate 17 fixed with the cross beam 2;

[0067] a plate body 13 fixed at the bottom end of the vertical beam 3;

[0068] a lead screw 15 rotationally connected with the plate body 13.

[0069] Further, the adjusting assembly further comprises:

[0070] a motor 14 fixed with the vertical beam 3, and the lead screw 15 is fixed with an output shaft of the motor 14.

[0071] Further, the adjusting assembly further comprises:

[0072] a second connecting seat 18 slidingly connected with the vertical beam 3, and the second connecting seat 18 is rotationally connected with a second tensioning shaft 21;

[0073] a transmission seat 16 fixed with the second connecting seat 18, and the transmission seat 16 is provided with a threaded hole, and the lead screw 15 passes through the threaded hole.

[0074] When the motor 14 works, the lead screw 15 is driven to rotate, and under the action of the transmission seat 16 and the threaded hole of the transmission seat 16, the second connecting seat 18 is driven to ascend, and the distance between the second tensioning shaft 21 and the two first tensioning shafts 5 is reduced, and the tension of the cloth is reduced.

[0075] Further, the transmission assembly comprises:

[0076] a connecting plate 20 fixed with the second connecting seat 18;

[0077] a second connecting block 9 rotationally connected with the connecting plate 20;

[0078] a sleeve 10 fixed on the second connecting block 9.

[0079] Further, the transmission assembly further comprises:

[0080] a first connecting block 8 rotationally connected with the first connecting seat 4;

[0081] a piston 19 slidingly arranged in the sleeve 10;

[0082] a sleeve rod 12 fixed with the piston 19, and the sleeve rod 12 is fixed with the first connecting block 8.

[0083] Further, the transmission assembly further comprises:

[0084] An electromagnetic valve 11 is arranged through the side wall of the sleeve 10.

[0085] When the switch of the electromagnetic valve 11 is closed, the gas in the sleeve 10 cannot be discharged in time when the second connecting block 18 is lifted by the working of the motor 14, so that the sleeve rod 12 and the piston 19 cannot slide along the sleeve 10, and thus when the second connecting block 18 is lifted, the two first connecting blocks 4 are pushed to quickly separate from each other by the second connecting block 9, the sleeve 10, the piston 19, the sleeve rod 12 and the first connecting block 8, so as to separate the two first tensioning shafts 5 from each other, reduce the bending angle of the cloth, and further reduce the contact area between the paper and the second tensioning shaft 21 and the first tensioning shaft 5, thereby further relieving the occurrence of the dead line phenomenon.

[0086] Specifically, the working principle is as follows: when in use, the cloth is first threaded through one of the first tensioning shafts 5, then through the second tensioning shaft 21, and finally through the other first tensioning shaft 5.

[0087] In the use process, the two first connecting blocks 4 are separated from each other by the action of the spring 7, so that the two first tensioning shafts 5 are separated from each other, so that the cloth remains in a tensioned state.

[0088] In the conveying process, if the detection mechanism identifies that the tension of the cloth is too large, the switch of the motor 14 can be turned on, and the motor 14 drives the screw rod 15 to rotate when working, and under the action of the transmission block 16 and the threaded hole on the transmission block 16, the second connecting block 18 is lifted, which reduces the distance between the second tensioning shaft 21 and the two first tensioning shafts 5, and thus reduces the tension of the cloth.

[0089] If the dead line phenomenon is more serious, before the motor 14 is turned on, the switch of the electromagnetic valve 11 is first closed, and then when the motor 14 works, the second connecting block 18 is lifted by the working of the motor 14, and because the electromagnetic valve 11 is closed, the gas in the sleeve 10 cannot be discharged in time, so that the sleeve rod 12 and the piston 19 cannot slide along the sleeve 10, and thus when the second connecting block 18 is lifted, the two first connecting blocks 4 are pushed to quickly separate from each other by the second connecting block 9, the sleeve 10, the piston 19, the sleeve rod 12 and the first connecting block 8, so as to separate the two first tensioning shafts 5 from each other, reduce the bending angle of the cloth, and further reduce the contact area between the paper and the second tensioning shaft 21 and the first tensioning shaft 5, thereby further relieving the occurrence of the dead line phenomenon.
