Description

Technical Field

[0001] The utility model relates to the technical field of filter rod forming, and particularly relates to an empty tube filter rod wire drawing and forming device. Background Art

[0002] When the tow passes through the steam forming module, under the condition of appropriate steam temperature, glycerol and the tow can be quickly solidified, and different shapes can be presented on the surface of the filter rod.

[0003] However, the hardness of the existing filter rod after forming is difficult to meet the increasing process requirements, so an empty tube filter rod wire drawing and forming device is needed. Summary of the Invention

[0004] In view of the above deficiencies existing in the prior art, the utility model provides an empty tube filter rod wire drawing and forming device to solve the problem that the hardness of the existing filter rod after forming is difficult to meet the increasing process requirements.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An empty tube filter rod wire drawing and forming device includes a thermal shell, with an input port and an output port provided on both sides of the thermal shell; a thermal forming cavity disposed inside the thermal shell and communicating with the input port and the output port; and a steam inlet provided on the surface of the thermal shell, with two steam inlets provided, and the steam inlets communicate with the thermal forming cavity, so as to be able to evenly spray glycerol and ensure the hardness of the filter rod after forming.

[0007] Further, the angle of the steam inlet is 40°, which is convenient for spraying glycerol onto the surface of the tow.

[0008] Further, the angle of the tow inlet at the connection between the input port and the thermal forming cavity is an arc-shaped angle of 35°, which is convenient for the tow to enter the thermal forming cavity.

[0009] Further, an external pressure gauge is provided on the surface of the thermal shell, so as to be able to observe the pressure condition of the thermal forming cavity in real time and facilitate the staff to adjust in time. Description of the Drawings
