Embodiment Construction

[0017] The embodiment of the present invention realizes the technical effect of adaptively adjusting the production tension by providing a double-roller shaft light blocking device.

[0018] The technical solutions in the embodiments of the present invention are to achieve the above-mentioned technical effects, and the general idea is as follows:

[0019] By pressing the two ends of the tensioning spring against the bearing and the adjusting bolt of the pressure roller respectively, the adaptive adjustment of the pressure of the pressure roller can be realized, and then the adaptive adjustment of the production tension can be realized, which ensures accurate detection and avoids tipping paper The paper tray has uneven winding. Specifically, when the pressure needs to be increased, the adjusting bolt is rotated in the positive direction, so that the adjusting bolt is pressed down to tighten the spring. The top tension spring is compressed, thereby exerting downward pressure on...

Abstract

The invention discloses a double-roller-shaft light blocking device. The two ends of each jacking spring correspondingly jack a bearing and an adjusting bolt of a corresponding press roller, and therefore the adaptive adjustment of the pressure of the press rollers can be achieved, then the adaptive adjustment of the production tension is achieved, the accurate detection is guaranteed, and the phenomenon that a tipping paper disc is irregularly wound is avoided. Specifically, when the pressure needs to be increased, the adjusting bolts are rotated in the forward direction, the adjusting bolts can press the jacking springs, the jacking springs are compressed, and therefore the downward pressure is applied to the bearings at the ends of the press rollers, and the purpose of increasing the pressure can be achieved. Otherwise, when the pressure needs to be reduced, the adjusting bolts are rotated in the reverse direction, the adjusting bolts can loosen the jacking springs, the jacking springs are released, and therefore the downward pressure which is applied to the bearings at the ends of the press rollers is reduced, and the purpose of reducing the pressure can be achieved.

Description

technical field [0001] The invention relates to the technical field of tipping paper detection, in particular to a double-roller shaft light blocking device. Background technique [0002] Tipping paper, also known as tipping paper, is a packaging material for cigarettes. It is specially used as the outer packaging of filters in cigarette factories. It is a special industrial paper. In the production process of tipping paper products, the stability of tension is very important. If the tension is lower than the tension required for production, the tipping paper product will vibrate and cannot be detected accurately; if the tension is too high, it will cause uneven winding of the tipping paper tray. Contents of the invention [0003] The invention realizes the technical effect of adaptively adjusting the production tension by providing a double-roller shaft light blocking device. [0004] The invention provides a double-roller shaft light blocking device, comprising: slide ...
