Problems solved by technology

[0003] In the papermaking process, when the paper breaks, the paper will enter the return roller with the net blanket, so that the paper will wrap around the return roller, causing the diameter of the return roller to become larger, and the net blanket will easily deviate or wear
[0004] At present, the production line is only equipped with an air jet tube near the coating cylinder, and the air jet tube is used to blow the broken paper to keep the paper away from the return roller. However, due to the direct operation by hand, it is close to the net blanket, which will cause mechanical damage. , there is a certain security risk

Embodiment 1

[0026] Embodiment one: if Figures 1 to 4 As shown, it is only one of the embodiments of the present invention, an automatic anti-winding device for the return roll of a paper machine, including a guide roll 10, a return roll 20, a clothing 30 passing through the guide roll 10 and the return roll 20 in turn, The air spray pipe 1 arranged on the outside of the net blanket 30 and the mounting plate 2 for supporting the air spray pipe 1, the end of the mounting plate 2 away from the air spray pipe 1 is connected to the fixed plate 3 through the adjustment part 4, The installation plate 2 rotates around the adjustment part 4, the air injection pipe 1 is connected with the air injection part 5 for controlling the flow of air in the air injection pipe 1, and the guide roller 10 is provided above the guide roller 10 for sensing the paper 40 and connecting with it. The air injection part 5 is electrically connected to the induction element 6 .

[0027] In papermaking production, the ...

Embodiment 2

[0032] Embodiment two, still as Figures 1 to 4 As shown, it is only one of the embodiments of the present invention. In order to make the processing effect of the automatic anti-wrapping device for the return roll of a paper machine of the present invention better and the degree of stability higher, the present invention also has the following design:

[0033] Firstly, the air injection pipe 1 is arranged on the top of the installation board 2 along the width direction of the installation board 2 , so as to ensure that the air flow will not be blocked by the installation board 2 when the air injection pipe 1 sprays air. Moreover, the number of the air injection pipe 1 is at least one. A plurality of air injection pipes 1 can be arranged at intervals along the top edge of the mounting plate 2, so that the air injection effect is better.

[0034] Of course, the outer peripheral wall of the jet tube 1 is provided with air outlet holes, and the jet airflow is ejected from the ai...

Abstract

The invention provides an automatic paper entanglement resistance device for a paper machine return roller, and relates to the technical field of papermaking equipment. The automatic paper entanglement resistance device includes a guide roller, a return roller, a net blanket passing the guide roller and the return roller in sequence, an air-jet tube arranged on the outer side of the net blanket, and a mounting plate for supporting the air-jet tube, the end part, away from the air-jet tube, of the mounting plate is connected with an adjustment part, the mounting plate rotates around the adjustment part, the air-jet tube is connected with an air-jet part for controlling on and off of air flow in the air-jet tube, and a sensing part for sensing paper and being electrically connected to the air-jet part is arranged on the upper part of the guide roller. The automatic paper entanglement resistance device for the paper machine return roller is simple in structure, the phenomenon of paper entanglement of the return roller is effectively avoided, paper entangled on the return roller does not need to be cleaned, the probability of mechanical injury to personnel caused by rotating equipmentis decreased, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, [0002] In particular, the present invention relates to an automatic anti-winding device for the return roll of a paper machine. Background technique [0003] In the papermaking process, when a paper break occurs, the paper will enter the return roller with the net blanket, so that the paper will wrap around the return roller, resulting in a larger diameter of the return roller, and the net blanket will easily run off or wear. [0004] At present, the production line is only equipped with an air jet tube near the coating cylinder, and the air jet tube is used to blow the broken paper to keep the paper away from the return roller. However, due to the direct operation by hand, it is close to the net blanket, which will cause mechanical damage. , there are certain security risks. [0005] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable ...
