Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings. For the sake of simplicity, the method and equipment will be combined for description. as attached figure 1 And attached figure 2 Shown is the equipment of an embodiment of the present invention, and the schematic diagram of the front view of the main process flow. Produced in this embodiment is the longitudinal multi-circle filter rod that contains two layers of inner rod and outer circle. The figure includes the main process flow in the present invention. omitted in this figure. Different from the prior art, the equipment of the production method in this embodiment includes five parts: inner rod tow opening unit 9, inner rod collection and rewinding device 25, outer rod tow opening unit 34, inner rod unwinding device 43 and vertical multi-circle forming unit 46. In the present invention, the original equipment of th...

Abstract

The invention discloses a method and equipment for producing a longitudinal multi-circle filter tip rod, which belong to the technical field of the method and the equipment for producing the cigarette filter tip rod. The equipment for implementing the method of the invention comprises five parts, namely an inner rod tow opening set (9), an inner rod collecting and rewinding device (25), an outer rod tow opening set (34), an inner rod unreeling device (43) and a longitudinal multi-circle forming set (46). By means of the production equipment of the prior art and by using a layered enwrapping production mode, the flow mode of the smoke gas can be changed according to the intention of the design concept of an inventor, and the harmful substances in the smoke gas are greatly reduced. The method has the advantages of reasonable design, simplicity, easiness, no need of too much equipment and no increase in production cost; and a completely new product is developed.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter rod production method and equipment thereof. The method produces a filter rod with multi-layer structure and different suction resistance of each layer, each layer is made of acetate fiber tow and each layer A longitudinal multi-round filter rod wrapped with molding paper and formed by longitudinal multi-round socketing. Background technique [0002] Cigarette filter rods in the prior art play an increasingly significant role in improving the overall performance of cigarettes, especially in the selective removal of harmful compounds in smoke. Ordinary cellulose acetate filter rods only have a simple trapping effect on smoke. Various so-called functional filter rods developed in recent years, though have various functions, can not change the flow direction of smoke in the filter rods, and all acetate filter rods in the prior art are It is a uniform rod composed of acetate tow material, w...
