Embodiment 1

[0031] Embodiment one: if Figures 1 to 3 As shown, it is only one of the embodiments of the present invention:

[0032] A filter rod surface coating device, comprising a feeding device 1, a forming device 2, a sizing device 3, a coating device 4 and a cooling device 5, the feeding device 1 includes a wire feeder 11 and is used to provide power for the filter rod to move The tractor 12 of the coating device 4 includes a coating box 6 and a coating box 7 for providing coatings for the filter rods in the coating box 6, and the coating box 6 includes a coating box for accommodating The central channel 61 of the filter rod, the coating part 62 with the paint chamber 64 inside and the attachment part 63 with the negative pressure chamber 65 inside, the paint chamber 64 is used to introduce the paint imported from the paint tank 7 into the The surface of the filter rod in the central channel 61 is used to form a coating film, and the negative pressure cavity 65 is used to generate ...

Embodiment 2

[0038] Embodiment two: if figure 2 As shown, it is only one of the embodiments of the present invention: the coating box 6 is the key part of the present invention, and the perfection of its work also needs to have the following designs:

[0039] First is the central channel 61 , and the end 61 of the central channel is provided with a filter rod inlet 611 and a filter rod outlet 612 respectively.

[0040] The filter rod enters the central channel 61 from the filter rod inlet 611 and exits the central channel 61 from the filter rod outlet 612 . The coating process is completed during passage through the central channel 61 .

[0041] Then the coating part 62,

[0042] In the above equipment, the paint chamber 64 is provided with a paint inlet 68 for connecting with the paint tank 7 .

[0043] The paint in the paint chamber 64 all comes from the paint tank 7 , so the paint chamber 64 needs to be provided with a paint inlet 68 for the paint in the paint tank 7 to flow into th...

Embodiment 3

[0052] Embodiment three: as image 3 As shown, it is only one of the embodiments of the present invention:

[0053] A method for coating a filter rod surface coating device, comprising the following steps:

[0054] S1: The feeding device conveys the filter rod material;

[0055] This corresponds to the power part in the above;

[0056] S2: The filter rod material is shaped by a forming device and fixed into a filter rod by a shaping device;

[0057] This corresponds to the molding part in the above;

[0058] S3: The filter rod passes through the coating device, and the coating device uniformly coats the surface of the filter rod with a thin film;

[0059]Corresponding to the coating part in the above mentioned here; coating a layer of thin film for the surface of the filter rod;

[0060] S4: The cooling device cools and solidifies the film on the surface of the filter rod.

[0061] Corresponding to the processing part in the above, the final optimization processing is pe...

Abstract

The invention provides a filter rod surface coating device and coating method and relates to the technical field of cigarette filter rods. The filter rod surface coating device includes a feeding device, a forming device, a forming device, a coating device and a cooling device. The feeding device includes a wire feeder and a retractor for providing power for movement of the filter rods. The coating device includes a coating box and a coating box for providing a coating for the filter rods in the coating box. The coating box includes a central channel for accommodating to-be-coated filter rods,a coating portion internally provided with a coating cavity and an attaching portion internally provided with a negative pressure cavity, the coating cavity is used for guiding the coating input fromthe coating box to the surfaces of the filter rods in the central channel to form a coating film, and the negative pressure cavity is used for generating a negative pressure in the central channel tomake the coating film adhere to the filter rods. The filter rod surface coating device and coating method can be applied to ordinary paper-free wiredrawing filter rods and special-shaped filter rodssimultaneously and are good in coating effect and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of cigarette filter rods, [0002] In particular, the present invention relates to a filter rod surface coating device and coating method. Background technique [0003] In order to filter certain harmful substances in cigarette smoke, filter sticks are all provided on most cigarettes at present. [0004] At present, in the conventional filter rod forming technology, a layer of special filter rod forming paper is wrapped around the main material cellulose acetate tow to form a filter rod for cigarettes. [0005] For example, the Chinese patent invention patent CN102657379A discloses a method and equipment for forming cigarette filter rods. The method is that in the process of continuously conveying the filter material of cigarettes forward and tending to be rod-shaped, there are various granular additives that are continuous at a certain time interval. output, and under the action of continuous delivery air...
