[0018] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0019] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly disposed on the other element; when an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0020] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0021] In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, the meanings of "a plurality" and "several" are two or more, unless otherwise specifically defined.

[0022] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in this technology to understand and read, and are not used to limit the limiting conditions under which this application can be implemented. Therefore, they do not have a technical essence. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that this application can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in this application.

[0023] The embodiments of this application are written in a progressive manner.

[0024] As shown Figures 1 to 3 in the figure, a glue spraying device for a cigarette making machine provided by the present application includes a paper tape conveying mechanism, a glue spraying mechanism and a paper pressing roller mechanism deployed on the mounting plate 10 of the cigarette making machine frame; the paper tape conveying mechanism includes: a plurality of conveying paper rollers 11 dispersedly arranged on the mounting plate of the machine frame; the glue spraying mechanism and the paper pressing roller mechanism are respectively arranged on both sides of the conveyed paper tape; the glue spraying mechanism includes a nozzle support arranged on the mounting plate of the machine frame and a scraping glue nozzle arranged on the nozzle support; the scraping glue nozzle includes a nozzle 1 and a scraping strip block 2 arranged on the nozzle; the scraping glue nozzle is connected to a glue supply chamber through a glue spraying pipeline; the paper pressing roller mechanism includes a rotating swing shaft 8 arranged on the mounting plate of the machine frame, a tooling seat 4 connected to the rotating swing shaft, and a paper pressing roller 6 arranged on the tooling seat; the paper pressing roller mechanism further includes a tooling clamping sleeve 5 sleeved on the working seat, a fitting surface is arranged on the outer periphery of the tooling clamping sleeve close to the scraping strip block, and a fitting block structure 12 matched and fitted with the fitting surface is arranged on the scraping strip block.

[0025] It should be noted that the glue spraying operation mode of the glue spraying device of the present application is the same as that of the existing glue spraying device; the scraping glue nozzle of the glue spraying device has a spraying working position, and the paper pressing roller has a paper tape pressing position; when the glue spraying device sprays glue on the tipping paper, the scraping glue nozzle rotates to the spraying working position, the paper pressing roller is activated to swing to the paper tape pressing position, the tipping paper tape 9 is pressed to the predetermined glue coating position of the scraping glue nozzle, and the scraping glue nozzle sprays glue on the paper tape; to ensure the glue spraying quality, the glue spraying surface of the scraping glue nozzle is basically parallel to the paper pressing roller under the normal operation state of the device. If the two are not parallel, it will cause the sprayed glue to shift, affecting the glue coating uniformity effect on the tipping paper. The glue spraying device of the present application uses the fitting surface of the tooling clamping sleeve to be matched and fitted with the fitting block structure of the scraping strip block, and can quickly complete the maintenance, debugging and installation of the scraping glue nozzle; it can be understood that the principle of the fitting block structure of the scraping strip block of the present application being matched and fitted with the fitting surface of the tooling clamping sleeve is that after the scraping glue nozzle and the paper pressing roller are fitted and debugged, it can ensure that the scraping glue nozzle rotates to the spraying working position, and the spraying surface of the scraping glue nozzle is parallel to the paper pressing roller rotating to the paper tape pressing position.

[0026] As an optional mode, the fitting surface is preferably a concave surface.

[0027] As a preferred embodiment, the spray head is provided with a threaded hole, and the scraping strip block is provided with a through hole 13 for connection. The through hole corresponds to the threaded hole, and the diameter of the through hole is larger than that of the threaded hole. The scraping strip block is provided with a fastening screw in the through hole to connect the threaded hole of the spray head, so as to tightly connect the scraping strip block and the spray head. In this embodiment, the scraping strip block is provided with a row of four circular through holes, and the diameter of the through hole is larger than that of the threaded hole. There is a relatively large gap between the screw and the circular through hole. When the screw is not in a tightened state, the entire scraping strip block can move up, down, left, and right relative to the threaded hole as a whole. The paper pressing roller mechanism further includes a tooling rod for connecting the piercing tooling seat to the frame mounting plate. As Figure 2 shown, after the tooling sleeve 5, the tooling rod 7, and the tooling base 4 of the present application are assembled, they form a complete tooling. A paper pressing roller 6 is fixedly inserted on this tooling, and the tooling is closely attached to the rotating swing shaft. The scraping strip block 2 is connected to the spray head 1 through a fastening screw 3. During the installation process, first loosen the fastening screw 3 with the aid of a maintenance tool, so that the scraping strip block 2 can move and adjust by means of the gap structure between the screw and the through hole, so that the fitting block structure of the scraping strip block is in contact with the fitting surface of the tooling bushing, completing the position adjustment of the scraping strip block. Subsequently, tighten the fastening screw 3 to fix the position of the scraping strip block 2. After completing the above steps, the maintenance installation of the scraping strip block 2 is completed.

[0028] As a preferred embodiment, the tooling bushing is designed with a notch for clamp connection, and bolt through holes for connection are provided on the two opposite sides of the notch. Bolts are set in the bolt through holes to lock and tighten. This structural design facilitates the disassembly and installation of the tooling bushing.

[0029] The present application also provides a cigarette making machine, including the above-mentioned glue spraying device. The beneficial effects of the cigarette making machine provided by the present application correspond to the beneficial effects of the glue spraying device provided by the present application, and will not be repeated here.

[0030] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
