Description

Technical Field

[0001] The utility model relates to the technical field of cigarette processing equipment, in particular to a tobacco shred suction and forming device for a cigarette making machine. Background Art

[0002] Tobacco suction and shaping is one of the core technologies of all cigarette making machines. The tobacco is conveyed into the air chamber through a mechanical throwing mechanism or a fluidized bed.

[0003] like Figure 1-4 As shown, in the prior art, a continuously running mesh suction belt is installed on the air chamber body. The air chamber body provides sufficient negative pressure to the suction channel through the mesh on the suction belt, so that the tobacco 1 can obtain sufficient speed to rise with the airflow, and the tobacco is adsorbed on the suction belt 2 to form a tobacco bundle. At the same time, the suction belt 2 is driven forward by the suction belt wheel, and the tobacco gradually thickens to form a tobacco bundle. Then, the excess tobacco away from the suction belt is trimmed by the flattening plate 3, and part of the tobacco close to the suction belt is retained so that the retained tobacco meets the rated tobacco rod weight requirements, and the excess tobacco is sent back to the storage area of ​​the wire feeding device. At the same time, the flattening plate groove 31 on the flattening plate 3 can compact the burning end of the cigarette, obtain a section with increased density of tobacco at the burning end, so that the tobacco forms a compacted end 6 with increased density to reduce the empty and thin ends of the cigarette. The tobacco trimmed by the flattening plate 3 is finally transported to the entrance end of the cigarette gun and wrapped into a tobacco rod by cigarette paper 4.

[0004] In the process of the tobacco bundle being driven forward by the suction belt, the wind chamber body 7 reduces the wind pressure to generate suction, the throwing roller 9 outputs the tobacco, and the down-blowing wind chamber 10 maintains a predetermined air pressure to blow air outward, bringing the tobacco from the throwing roller to the tobacco channel 8.

[0031] In a specific embodiment, the tobacco suction and forming device of the cigarette making machine includes an air chamber body, a tobacco front guide rail 101, a tobacco rear guide rail, a suction belt, and an inclined boosting component arranged on the guide working surface of at least one of the tobacco front guide rail 101 and the tobacco rear guide rail. The inclined slope of the inclined boosting component rises in the direction from the tobacco front guide rail 101 to the tobacco rear guide rail. The air chamber body forms a negative pressure on the tobacco channel and adsorbs the tobacco in the tobacco channel through the mesh holes arranged on the suction belt. In the process of the tobacco passing through the tobacco front guide rail 101 and the tobacco rear guide rail, the tobacco is supported by the inclined surface of the inclined boosting component, thereby realizing a boosting operation on the tobacco.

[0032] By arranging an inclined pressurizing component on the working surface of at least one of the front tobacco guide rail 101 and the rear tobacco guide rail, during the operation, the air chamber body forms a negative pressure on the tobacco channel through the mesh holes arranged on the tobacco suction belt, and adsorbs the tobacco in the tobacco channel. In the process of passing through the front tobacco guide rail 101 and the rear tobacco guide rail, the tobacco is supported by the inclined surface of the inclined pressurizing component, thereby realizing the pressurizing operation, that is, the tobacco is subjected to the component force of the pressurization toward the tobacco suction belt, thereby further compacting the tobacco, so as to ensure that the tobacco layer on the tobacco suction belt is tight and uniform, thereby improving the quality of cigarettes.

[0033] In the present application, the tobacco is pressurized by an inclined pressurizing component to improve the compactness and uniformity of the tobacco layer on the suction belt, and there is no limitation on the number, setting position, inclination angle and setting method of the inclined pressurizing component.

[0034] In order to improve the pressurization effect on the tobacco, generally, there are multiple inclined pressurization components, and the multiple inclined pressurization components are distributed in an array in the direction from the tobacco front guide rail 101 to the tobacco rear guide rail.

[0035] In addition to the above-mentioned array distribution of the inclined boost components in the present application, staggered distribution or other methods may also be adopted. For example, the staggered distribution is that the inclined boost components parallel to the direction of movement of the tobacco are staggered at both ends in the vertical direction, such as adjacent inclined boost components in the vertical direction are delayed or advanced by a certain distance in the direction of movement of the tobacco.

[0036] The present application does not limit the formation method of the inclined boost component. In one embodiment, the inclined boost component is a twill boost component 102, and the twill boost component 102 is a twill boost component 102 formed by mechanically processing the working surface of the tobacco front guide rail 101 or the tobacco rear guide rail.

[0037] After the tobacco is filled on the suction belt, a twill pressurizing component 102 with a smaller inclination angle is directly processed on the front and rear guide rail working surfaces of the tobacco before the leveling plate trims the tobacco to form a twill pressurizing area, so as to obtain a component force that pressurizes the tobacco toward the suction belt, thereby further compacting the tobacco to ensure that the tobacco layer on the suction belt is tight and uniform. Compared with the existing means of ensuring tobacco compaction, there is no need to increase additional energy consumption, and the tobacco passing through the pressurized section is rigidly compacted indiscriminately, thereby improving the quality and qualified rate of cigarettes.

[0038] The present application does not limit the formation method of the twill pressurization component 102, which may be processed by a milling machine, or may be achieved by chemical etching, plasma etching, or other methods.

[0039] The twill pressurizing component 102 in the present application is used to form an inclination to achieve pressurization, and there is no limitation on the inclination method. The inclined surface of the twill pressurizing component 102 is a plane or a curved surface, or other inclined structures.

[0040] In addition to the above-mentioned processing of the original tobacco front guide rail 101 or the tobacco rear guide rail, other methods can also be used in the present application. However, the processing of the original tobacco front guide rail 101 or the tobacco rear guide rail requires processing of the guide rail, which is prone to damage, and the corresponding components need to be disassembled, processed, and installed, and the entire process operation is relatively cumbersome.

[0041] In another embodiment, the inclined pressurizing component is an inclined pressurizing block 103, and the inclined pressurizing block 103 is bolted, bonded or welded to the tobacco front guide rail 101 or the tobacco rear guide rail.

[0042] By using an independent inclined supercharging block 103 as an inclined supercharging component, it can be processed independently and then installed at the corresponding position of the guide rail. In this process, the guide rail will not be damaged. If the inclined supercharging component does not meet the requirements, it can be replaced, which reduces the use cost and improves the supercharging efficiency of the tobacco.

[0043] The present application does not limit the material, size, processing method, installation method, etc. of the inclined boosting block 103.

[0044] In the above two structures, the first structure needs to process the guide rail. If the inclination angle of the inclined surface needs to be changed, it needs to be processed again, and related disassembly and installation are required. Moreover, the inclination angle can only be increased, and the cost of use is relatively high. In the second structure, the related inclined booster block 103 needs to be replaced, which needs to be disassembled, reprocessed, or replaced. Therefore, no matter which method is used, complicated processes are required in the adjustment of the inclination angle.

[0045] In order to improve the efficiency of adjustment, in one embodiment, the tobacco suction and forming device of the cigarette making machine also includes a gap arranged on the working surface of the tobacco front guide rail 101 or the tobacco rear guide rail, and an inclined plate 104 is arranged in the gap, and the inclined plate 104 is inclined and rises in the direction from the tobacco front guide rail 101 to the tobacco rear guide rail to form the boosting component.

[0046] By setting the inclined plate, it is sufficient to form a gap on the working surface, and the subsequent process only requires adjustment of the inclined plate 104. Moreover, the installation with the working surface becomes simpler and can be locked with a plug screw 105 or other components.

[0047] In order to further meet the needs of different processes and change the height of its inclined surface, in one embodiment, the tobacco suction and forming device of the cigarette making machine also includes a base arranged at the bottom of the inclined plate 104 and a height adjuster arranged on the base, and the height adjuster is connected to the inclined plate 104 for adjusting the overall height of the inclined plate 104.

[0048] By providing a base and a height adjuster, and connecting the height adjuster to the inclined plate 104, the overall height of the inclined plate 104 is adjusted, so that in different processes, different process requirements can be achieved by adjusting the height of the inclined plate 104.

[0049] It should be pointed out that the present application does not limit the structure of the height adjuster and the height adjustment method. It can be controlled by a cylinder, or by a servo motor controlling a planetary ball screw, or by other structures.

[0050] Similarly, in different process flows, inclined planes with different inclination angles are required. In order to improve the efficiency of inclination angle control and achieve precise control, in one embodiment, the tobacco suction and forming device of the cigarette making machine also includes an angle adjuster arranged on the base, and the angle adjuster is connected to the inclined plate 104 for adjusting the inclination angle of the inclined plate 104.

[0051] An angle adjuster is provided, and the angle adjuster is connected to the inclined plate 104, and is used to adjust the inclination angle of the inclined plate 104. The angle adjustment can be performed by using a rotating component, or one end can be fixed and the other end can be raised or lowered, or both ends can be moved in different directions at the same time, such as one end is raised and the other end is lowered, or other structures, such as a hydraulic mechanism is provided at one end to achieve height adjustment by increasing or decreasing the liquid.

[0052] In order to further improve the management efficiency and control efficiency of the inclined plate 104, in one embodiment, the tobacco suction and forming device of the cigarette making machine also includes a controller and a display connected to the height adjuster and the angle adjuster, and the controller is used to control the operating status of the height adjuster and the angle adjuster after receiving external instructions, and the display is used to display the operating status of the height adjuster and the angle adjuster and the height and inclination angle of the inclined plate 104.

[0053] The control method of the controller is not limited in the present application. It can be controlled according to preset instructions, or temporarily receive external instructions for control, or be controlled by other control methods. The display can temporarily display one parameter of the tilting plate 104, or it can display multiple parameters of the tilting plate 104 at the same time.

[0054] The present application does not limit the size and specific parameters of the inclined boost component. Generally, the inclined boost component has a length of 150-160 mm, a width of 0.5-1 mm, and an inclination angle of 2°-3°.

[0055] To sum up, the tobacco suction and forming device of the cigarette making machine provided in the embodiment of the present application is provided with an inclined boosting component on the working surface of at least one of the tobacco front guide rail and the tobacco rear guide rail. During operation, the air chamber body forms a negative pressure on the tobacco channel through the mesh holes provided on the tobacco suction belt, and adsorbs the tobacco in the tobacco channel. In the process of passing through the tobacco front guide rail and the tobacco rear guide rail, the tobacco is supported by the inclined surface of the inclined boosting component, thereby realizing the boosting operation, that is, the tobacco is subjected to the component force of boosting toward the tobacco suction belt, thereby further compacting the tobacco, so as to ensure that the tobacco layer on the tobacco suction belt is tight and uniform, thereby improving the quality of cigarettes.

[0056] The above is a detailed introduction to the tobacco shred suction and forming device for cigarette making machines provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
