Middle line glue multi-stage slit gluing device with self-cleaning function

Abstract

The invention relates to a midline glue multi-stage slit gluing device with a self-cleaning function, and belongs to the technical field of tobacco equipment. Comprising a mounting seat and a gluing unit, a mounting groove is formed in the mounting seat, a gluing unit is mounted in the mounting groove, and the gluing unit comprises an upper die head, a lower die head and a middle die piece arranged between the upper die head and the lower die head; a glue inlet channel I is formed in the mounting base, a glue outlet groove penetrating through the top of the middle mold piece is vertically formed in the side face of the middle mold piece, and a glue guide channel with one end communicated with the glue outlet groove and the other end communicated with the glue inlet channel I is formed in the lower mold head. The slit gluing is adopted, the leveling time of glue on the molding paper tape is extremely short, the gluing thickness is more uniform, the glue permeation of the high-permeability molding paper and the contact between the paper tape and the die lip surface caused by non-uniform glue mark thickness are effectively avoided, the paper ash is not easy to generate, and the stability of the gluing process is ensured; and the gluing thickness can be adjusted by adjusting the height of the middle mold sheet, so that the gluing thickness is more convenient to adjust.

Description

technical field [0001] The invention belongs to the technical field of tobacco equipment, in particular to a self-cleaning midline glue multi-stage slit gluing device. Background technique [0002] In the production process of cigarette filter rods, the forming paper should be glued with centerline glue and sealing glue before wrapping the filter material, and then the process of sealing, shaping, cutting and other processes should be carried out to form a filter rod of a set length. Among them, the purpose of gluing the center line glue is to bond and fix the filter material on the forming paper, so as to avoid the relative position of the filter material and the forming paper slipping under the action of other external forces during the cutting or conveying process of the filter rod, thus causing unqualified filter rod. [0003] At present, the central line glue gluing method of the filter rod forming machine mostly adopts two kinds of gluing methods: striker-type dispens...

AI Technical Summary

Problems solved by technology

[0003] At present, the middle line gluing method of the filter rod forming machine mostly adopts two kinds of gluing methods: the needle dispensing valve gluing and the non-contact atomizing gluing method. , The nozzle and the paper tape are in contact with each other, which is easy to cause nozzle wear and paper dust. The paper dust mixes with the glue at the nozzle to produce glue scale, and the accumulation of glue scale can easily cause the glue to break. Silky or point-like dry glue will pollute the equipment, and it is inconvenient to adjust the thickness and uniformity of the glue, which will easily lead to unstable adhesion, and the way of glue is greatly affected by the physical properties of the glue, such as viscosity and solid content. Inconvenient to maintain
