Tipping paper gluing apparatus and gluing method as well as coiling machine

Abstract

The invention relates to a tipping paper gluing apparatus and a gluing method as well as a coiling machine. The tipping paper gluing apparatus comprises a gluing wheel and a wrap angle adjusting mechanism, wherein the wrap angle adjusting mechanism is used for adjusting a contact wrap angle beta between tipping paper and the gluing wheel from a paper inlet side of the gluing wheel. By adopting thetipping paper gluing apparatus and the gluing method, the contact wrap angle beta between the tipping paper and the gluing wheel can be adjusted only from the paper inlet side of the gluing wheel inthe adjustment process, and the contact wrap angle beta does not need to be adjusted from a paper outlet side, so that the contact wrap angle beta is freely adjusted on the premise of not influencinga gluing position of the tipping paper, thereby increasing a ventilation rate of a filter tip of a cigarette product, and enabling the ventilation rate of the filter tip of the cigarette product to meet the quality standard.

Description

technical field [0001] The invention relates to the technical field of tobacco machinery, in particular to a tipping paper gluing device, a gluing method and a coiling machine. Background technique [0002] The crimper is a special equipment used by cigarette industry enterprises to produce filter cigarettes. Tipping paper is one of the important materials for producing cigarettes, and tipping paper needs to be glued before use, such as figure 1 As shown, the existing gluing device includes a glue roller a1, a glue cylinder a2, a glue control roller a3, a glue amount adjusting nut a4, a butterfly spring a5, a paper lifting roller a6 and a bracket a7. When the gluing device is in operation, the control rubber wheel a3 and the upper rubber wheel a1 are in close contact under the action of the butterfly spring a5, and the two move towards each other to form a rubber pile. Such as figure 2 As shown, the rubber control wheel a3 has a concave part a31, a convex part a32, and a...

Problems solved by technology

[0007] However, if Figure 6 As shown, the pre-punched brand has strict requirements on the position of the glue map, that is, the width of the first lap a12 and the second lap a13 between the glue-free area a9 of the tipping paper must be consistent, otherwise it will affect the pre-punched The amount of perforation coverage that causes fluctuations in the filter ventilation rate

The position of the glue map is also achieved by adjusting the paper lifting wheel a6 on the support a7 to change the path length of the tipping paper CD section. The phase of the wheel and the cutting wheel is determined, so the contact wrap angle β cannot be adjusted freely in the prior art
