Problems solved by technology

[0004] The existing paperless hollow molding equipment is to add hot steam and cold dry gas to the forming section of the bong, and wrap it with a plastic cloth tape to prepare a hollow filter rod in a conventional molding method. Since the cloth tape needs to be in direct contact with the hot steam, The liquid droplets formed after the hot steam condenses will stay on the cloth tape. The cloth tape can only be made of plastic-like material with threads on the surface. Therefore, the hollow filter rods prepared by this equipment also have threads on the surface. There will be a gap between the forming paper and the forming paper during use, resulting in poor composite effect and subsequent application effect

preparation example Construction

[0048] A kind of drawing type preparation method of hollow filter rod, comprises the following steps:

[0049] The two groups of fiber tows are respectively opened on the upper opener and the lower opener of the double-layer opener;

[0050]Spray glyceride to the tow after opening;

[0051] Fill the annular cavity of the high-pressure nozzle with high-pressure air, and the high-pressure air is ejected from the nozzle through the through hole on the inner wall of the annular cavity, forming a local negative pressure, sucking the tow, and realizing the high-pressure delivery of the tow;

[0052] Subsequently, the tow is conveyed into the forming hot mold, heated and shaped under the action of high-temperature steam, and then enters the forming cold mold assembly to fully cool;

[0053] The shaped filter rods are cut, plated, and solidified to obtain hollow filter rods.

[0054] In some embodiments, the pressure of the high-pressure gas fed into the high-pressure nozzle is 0.02...

Embodiment

[0059] Such as figure 1 As shown, a drawing-type preparation equipment for hollow filter rods includes a double-layer opener 8, a high-pressure wire feeder 6, a forming module 5, a bong assembly 4, a cutter head box 3, and a tray loading machine arranged in sequence. 2 and cold dryer 1.

[0060] Such as figure 2 and image 3 As shown, the double-layer opening machine 8 includes an upper layer opening mechanism and a lower layer opening mechanism; both the upper layer opening mechanism and the lower layer opening mechanism are provided with a threaded roller servo drive mechanism and a glyceride spraying chamber 7 in sequence. The thread roller servo drive mechanism is driven by a motor to rotate, providing power for the movement of the tow. The bottom of the glyceride spray chamber 7 is provided with a spray head, and the circulation pump is connected to the bottom of the glyceride spray chamber 7 and the spray head respectively. The circulation pump pumps the glyceride i...

Abstract

The invention discloses drawing type preparation equipment and method for a hollow filter stick, and the preparation equipment comprises an opener which is a double-layer opener and comprises an upper-layer opening mechanism and a lower-layer opening mechanism; a high-pressure pipe tobacco feeder which is located on the downstream of the opener and comprises a high-pressure nozzle, wherein the high-pressure nozzle is of a hollow cylindrical structure, a core rod is located on the central axis of the high-pressure nozzle, an annular cavity is formed in the high-pressure nozzle, a through hole is formed in the inner side wall of the annular cavity, and the annular cavity is connected with a compressed air source; a forming module which is located on the downstream of the high-pressure pipe tobacco feeder, a conical flow guide part, a forming hot die and a forming cold die assembly are sequentially arranged in the moving direction of the pipe tobacco bundle, the forming hot die is connected with a steam source, and the forming cold die is connected with a cold air source. The equipment can be matched according to the hardness and quality requirements of the filter stick, and the effect of forming the filter stick is ensured.

Description

technical field [0001] The invention relates to the technical field of filter rod preparation, in particular to a drawing-type preparation device and a preparation method for a hollow filter rod. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] The filter rod is a round rod with filtering performance and a certain length, which is made of filter materials (such as fiber tow for tobacco and core paper, etc.) as raw materials, processed and rolled. The filter tip refers to a cylinder that filters certain substances in cigarette smoke (such as tar, nicotine, etc.) and is installed on the suction end of a cigarette after being cut. component. The filter also prevents cigaret...
