Embodiment Construction

[0022] Such as figure 1 The forming equipment for a coaxial core filter rod without a paper wrapping shown in the figure has an outer layer tow transmission mechanism and an inner layer tow transmission mechanism, a combined opening mechanism, an inner layer without a paper wrapping filter core curing and shaping mechanism, The outer layer has no paper bag filter element for solidification and shaping, composite molding mechanism, and filter rod lead-out mechanism.

[0023] The outer layer tow transmission mechanism and the inner layer tow transmission mechanism are jointly connected to the combined opening mechanism;

[0024] The combination opening mechanism has upper and lower rows of opening branches, which respectively open the inner layer tow and the outer layer tow, and the two groups of tows are opened and the walking speed is synchronized; the outer layer of tow passes through and opens in the upper row , the inner layer tow is passed and opened in the lower row.

Abstract

The invention discloses forming equipment of a paper-parcel-free coaxial core filter stick. The forming equipment is provided with two filament tow conveying mechanisms arranged in parallel, a combined opening mechanism, an inner-layer paper-parcel-free filter stick solidifying and shaping mechanism, an outer-layer paper-parcel-free filter stick solidifying and shaping and composite forming mechanism and a guiding-out mechanism. The inner-layer paper-parcel-free filter stick solidifying and shaping mechanism heats inner-layer filament tows by steam, and paper-parcel-free inner core filter sticks are made at first; and then an outer layer is shaped by heating through steam. According to the forming equipment, the inner layer and the outer layer are sequentially formed, the two layers are spaced clearly, a forming production line is short, and the manufacturing efficiency is high.

Description

technical field [0001] The invention relates to a filter rod forming device and an operating method thereof. Background technique [0002] In the present invention, "wrapped without paper" means that the filter rod is not or does not need to be wrapped with sheet materials such as forming paper. [0003] The invention with the Chinese patent application number 2016110660543 provides a pressure drop measuring device for a paperless filter rod, which includes an inclusion mechanism, a large flow negative pressure feeding device, a small flow negative pressure drop measuring device, and an air blowing discharge device , Solenoid valve group and gas pipeline that can switch the control gas circuit. The key molding parts of the paperless filter rod molding equipment are not disclosed. [0004] The invention of Chinese patent application number 2015101239777 provides a hollow filter rod forming equipment, which has a shell mold and a core mold located at the center of the shell ...
