Will not loose.

Description

Roller of a rewinding machine

technical field

The utility model relates to a pressing roller, in particular to a pressing roller of a rewinding machine. the

Background technique

The purpose of the rewinding machine is to rewind the paper rolls (called base paper rolls) produced by the paper machine in sequence, and the paper is made into finished paper after rewinding. One of the main tasks in the rewinding process is to control the diameter of the finished paper roll to meet the factory requirements. the

When the collecting roller of the rewinding machine collects the paper roll, as the diameter of the paper roll becomes larger and larger, the paper roll will become looser and looser due to the inertia of the paper roll, and will not move closer to the center of the collecting roller. Therefore, there needs to be a pressure roller to compress the paper roll so that the collected paper roll on the collection roller will not loosen. the

Utility model content

In order to overcome the technical defects, the purpose of this utility model is to propose a rewinding machine pressure roller that can prevent loose paper rolls. the

In order to achieve the above object, the utility model adopts the following technical solutions:

A pressure roller for a rewinding machine, including a pressure roller and a pneumatic device; it is characterized in that: the pressure roller is arranged close to the collection roller; two first support vertical bars arranged in parallel and One end of the second support vertical bar; the other end of the first support vertical bar and the second support vertical bar is fixed with the first support horizontal bar arranged parallel to the pressing roller; the second support vertical bar is also provided with the first support bar parallel to the first support vertical bar A second support bar with the same axis line as the support bar; the end of the second support bar that is not connected to the second support bar is also fixed with the first support bar and the second support bar parallel to the first support bar. Three supporting vertical bars; the third supporting vertical bar acts on a telescopic rod; the telescopic rod acts on a cylinder.

The explanation of the above scheme and the further scheme are as follows:

In the above scheme, a pressure gauge is installed on the air passage connecting the cylinder to the gas station.

Due to the use of the above-mentioned technical solutions, the utility model has the following advantages compared with the prior art:

The new implementation can realize the compaction of the paper rolls collected on the collecting roller, and can adjust the pressing angle of the pressing roller according to the diameter of the paper roll, so that the paper rolls collected on the collecting roller can maintain a high degree of compactness. Will not loose.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment: see shown in Fig. 1:

A pressure roller for a rewinding machine, comprising a pressure roller 4 and a pneumatic device; the pressure roller 4 is arranged close to the collection roller 3; two first support vertical bars 5 arranged in parallel are fixed at both ends of the pressure roller 4 and one end of the second support vertical bar 6; the other end of the first support vertical bar 5 and the second support vertical bar 6 is fixed with the first support cross bar 8 that is arranged in parallel with the pressure roller 4; the second support vertical bar The bar 6 is also provided with a second support cross bar 9 that is consistent with the axis line of the first support cross bar 8; the end of the second support cross bar 9 that is not connected with the second support vertical bar 6 is also fixed with the first support bar 9. The vertical bar 5 and the third supporting vertical bar 7 parallel to the second supporting vertical bar 6; the telescopic rod 10 acts on the third supporting vertical bar 7; the air cylinder 11 acts on the telescopic rod 10. A pressure gauge 12 is installed on the air passage connecting the cylinder 11 with the gas station.

The conveying roller 1 , collecting roller 3 and pressure roller 4 are all installed on the mechanical panel 2 . The paper roll 13 passes through the conveying roller 1 and is collected and rewound on the collecting roller 3 , and the pressing roller 4 is arranged close to the collecting roller 3 . Telescopic link 10 acts on the third support vertical bar 7, and pressure gauge 12 is installed on the air channel that cylinder 11 is connected with gas station. By observing the pressure gauge 12, the intake air is kept at a constant pressure, so the force exerted by the cylinder 11 on the telescopic rod 10 can be kept constant. Further, the force exerted by the telescopic rod 10 on the third support vertical bar 7 is constant. Therefore, through the force transmission of a plurality of supporting horizontal bars and supporting vertical bars, the pressure roller 4 can generate a constant pressing force on the collecting roller 3 , and the pressing roller 4 can always be in close contact with the collecting roller 3 . the

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to enable those familiar with this technology to understand the content of the present utility model and implement it accordingly, and not to limit the protection scope of the present utility model. All equivalent changes or modifications made according to the utility model shall be covered within the protection scope of the utility model. the
