Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette-making equipment, and particularly relates to a cigarette tongue and a cigarette forming device of a cigarette-making machine. Background Art

[0002] The cigarette tongue plays a crucial role in cigarette manufacturing. It is a key part in the cigarette rolling and forming system of the cigarette-making machine. Its main function is to apply pressure to the cut tobacco before it enters the small pressing plate, so that the cut tobacco can smoothly enter the small pressing plate and be compressed in the conical semi-circular channel of the cigarette tongue. In this way, the cut tobacco bundle can be properly compressed and shaped after entering the small pressing plate, thus ensuring the quality and shape of the cigarette. In addition, the cigarette tongue also plays an important role in the forming process of the cut tobacco bundle in the cigarette gun. The cigarette gun cooperates with the cigarette tongue. The cigarette tongue compresses the cut tobacco bundle for the first time to make it circular, and at the same time, the cigarette paper forms a "U" shape.

[0003] In the actual production process, the cut tobacco flakes in the tobacco feeding section are prone to overall shedding of the cut tobacco during subsequent processes such as cutting, compounding, and transmission, resulting in defective cigarettes. To avoid the overall shedding of the cut tobacco, a production process of applying glue on the reverse side of the cigarette paper in the tobacco feeding section is used, that is, applying glue on the wrapping surface of the cigarette paper to make the cut tobacco flakes and the cigarette paper adhere to each other, playing a role in fixing the cut tobacco flakes in the cigarette rod and effectively avoiding the shedding of the cut tobacco flakes during subsequent processes. After using the reverse side glue application process, in the working area of the cigarette tongue, the cigarette gun is arranged below the cigarette tongue, and an arc-shaped groove with a continuously decreasing diameter is arranged on the cigarette gun. Driven by the cigarette gun, both sides of the cigarette paper roll up upward. During the rolling-up process, the cigarette paper is prone to contact both sides of the cigarette tongue, and the glue liquid solidifies on the surface of the cigarette tongue after contacting the cigarette tongue, resulting in a large amount of accumulated glue. The accumulated glue is prone to cause the cigarette paper to jam and stop the machine, thereby reducing the production stability. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cigarette tongue and a cigarette forming device of a cigarette-making machine, which solves the problem of the contact between the cigarette paper and the cigarette tongue, reduces the number of equipment shutdowns, and improves the production stability.

[0026] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model and the prior art, the specific implementation manners of the present utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other implementation manners can also be obtained. In addition, the terms related to directions only represent the relative positional relationships between components, rather than absolute positional relationships.

[0027] The embodiment of the present utility model provides a tobacco tongue of a cigarette making machine and a cigarette forming device. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , mainly including a fixing part 1, a wire pressing part 2 and an air cavity 3.

[0028] In a first aspect, a tobacco tongue of a cigarette making machine provided by the present application includes a fixed part 1 and a wire pressing part 2 which are connected to each other, and an air cavity 3 penetrating through the fixed part 1 and the wire pressing part 2; a tobacco gun is arranged below the wire pressing part 2, cigarette paper and cut tobacco are carried on the tobacco gun, the lower surface of the wire pressing part 2 and the upper surface of the tobacco gun form a wire pressing channel, the cigarette paper and the cut tobacco are transported on the tobacco gun and pass through the wire pressing channel, when the cut tobacco passes through the wire pressing channel, the wire pressing channel compresses the cut tobacco into a round strip shape, and the air cavity 3 blows air towards the cigarette paper to separate the wire pressing part 2 from the cigarette paper. Compared with the prior art, the cigarette paper is driven by the tobacco gun and curls upwards on both sides. During the curling process, the cigarette paper is likely to contact both sides of the tobacco tongue, and after the glue solution contacts the tobacco tongue, it solidifies on the surface of the tobacco tongue, thereby generating a large amount of accumulated glue. In the present application, the air cavity 3 blows air towards the cigarette paper, and the air blown by the air cavity 3 forms an air curtain. The air curtain separates the cigarette paper from the tobacco tongue, the cigarette paper does not contact the tobacco tongue, and no glue accumulates on the surface of the tobacco tongue, thereby reducing the number of equipment shutdowns and improving production stability.

[0029] In the present application, the air cavity 3 includes an air inlet 31 arranged on the fixed part 1, air outlets 32 arranged on both sides of the wire pressing part 2, and a transition air duct 33 for communicating the air inlet 31 and the air outlets 32. Preferably, as Figure 2 、 Figure 3 shown, the air inlet 31 is arranged on the upper surface of the tobacco tongue of the cigarette making machine. The tobacco tongue of the cigarette making machine further includes a blower that communicates with the air inlet 31 and is used to provide positive pressure air towards the air inlet 31. The blower blows air, the air enters the interior of the transition air duct 33 from the air inlet 31, and then passes through the transition air duct 33 and blows out from the air outlets 32 to form an air curtain, thereby separating the cigarette paper from the tobacco tongue.

[0030] Furthermore, if the wind force of the air curtain is too large, it will damage the process shape of the cigarette paper below the tobacco tongue, thereby affecting the stability of the cigarette paper in the subsequent cigarette production process. Therefore, as Figure 3 shown, the transition air duct 33 is in an inverted Y shape. The inverted Y shape setting causes the air entering the air inlet 31 to be split at the end of the transition air duct 33 and then blown out through the air outlets 32 on two different sides. The design of one air inlet 31 and two air outlets 32 is easy to implement, and at the same time, the two air outlets 32 split the air entering from the air inlet 31, thereby reducing the wind force of the air curtain.

[0031] Preferably, a filter screen can be arranged on the air outlet 32 to prevent the air from bringing dust and other impurities into the cut tobacco, improving the production quality of the cigarettes.

[0032] In the present application, referring to Figure 5 、 Figure 6, before the cigarette paper enters the tongue area, both sides of the cigarette paper have already warped. Therefore, arc-shaped surfaces 5 are provided on both sides of the wire pressing part 2, and the air outlet 32 is arranged on the arc-shaped surface 5, so that the air blown out from the air outlet 32 blows towards the cigarette paper in an obliquely downward direction, thereby improving the partition effect of the air curtain. And according to the cigarette production process, at the tail end of the tongue (taking Figure 2 the perspective as the reference benchmark, taking Figure 2 the upper end of the tongue in the middle as the tail end of the tongue, taking Figure 2 the lower end of the tongue in the middle as the front end of the tongue), the cigarette paper needs to be closed. Setting the arc-shaped surface 5 can avoid paper jams and play a role in protecting the cigarette paper.

[0033] In this application, the air outlet 32 is strip-shaped. The air outlet 32 is arranged at the front end of the tongue and extends along the wire pressing direction of the wire pressing channel. Compared with the circular air outlet, the width of the air curtain increases for the strip-shaped air outlet 32, the contact range between the air curtain and the cigarette paper increases, the partition range and partition effect of the air curtain are improved, and at the same time, the effect of reducing the wind force of the air curtain is also achieved.

[0034] In this application, a plurality of fixing holes 6 are provided on the fixing part 1. The fixing holes 6 are arranged in a straight line on the fixing part 1. The section of the fixing hole 6 (taking Figure 2 the tangent line at point A in the middle as the cutting direction) is convex-shaped. Threads are provided inside the end with a smaller diameter of the section of the fixing hole 6. The tongue is fixed to the machine frame in a screwed manner. The end of the screwed component can be embedded inside the end with a larger diameter of the section of the fixing hole 6 to reduce the space occupied by the installation of the tongue and make the installation of the tongue more beautiful.

[0035] In this application, an inclined surface 7 is further provided at the front end of the tongue. The inclined surface 7 is used to extend the length of the wire pressing channel and improve the wire pressing quality and the production quality of the cigarette.

[0036] In this application, the tongue is made of aluminum alloy material, or can also be made of materials such as polytetrafluoroethylene.

[0037] In a second aspect, the cigarette rod forming device provided by this application includes a wing plate, a cigarette machine tongue, and a pressing plate arranged in sequence along the moving direction of the tobacco shreds (such as Figure 4 the direction indicated by the arrow B in the middle). A suction belt is provided on the wing plate, and tobacco shreds are adsorbed on the suction belt. The wing plate drives the suction belt to rotate and removes the tobacco shreds on the suction belt above the cigarette gun. A cigarette paper is provided on the cigarette gun. The tobacco shreds falling from the suction belt are received by the cigarette paper. The cigarette gun drives the cigarette paper and the tobacco shreds to move. An arc-shaped groove with a continuously decreasing diameter is provided on the cigarette gun. The states of the cigarette paper and the tobacco shreds are as Figure 5 , Figure 6 shown. When the cigarette paper and the tobacco shreds are displaced to the position where the tongue is located, the tongue will compress the tobacco shreds to make the tobacco shreds cylindrical, and then move to the position of the pressing plate. The pressing plate closes the cigarette paper, thereby completing the cigarette rod forming process.
