Description
Technical Field
[0001] The utility model relates to the technical field of cigarette manufacturing, in particular to a wire suction and forming device for a cigarette making machine. Background Art
[0002] The principle of wire suction and forming in a cigarette making machine is that under the action of a fan, loose cut tobacco is conveyed into a wire suction channel. The cut tobacco includes tobacco leaves and tobacco stems. The cut tobacco is adsorbed on a wire suction belt and moves together with the wire suction belt. During the movement, more and more cut tobacco is adsorbed on the wire suction belt, and finally a cut tobacco bundle with a certain thickness is formed. The prior art conducts wire suction and forming operations through a wire suction and forming device of a cigarette making machine. As an important part of the cut tobacco conveying of the cigarette making machine, the wire suction and forming device of the cigarette making machine directly affects the stability of equipment operation and the internal quality of cigarette products.
[0003] In the existing wire suction and forming device of a cigarette making machine, generally, cut tobacco is conveyed upward through a wire suction channel, and then the cut tobacco is adsorbed by a wire suction belt and the cut tobacco is moved horizontally. When conveying tobacco stems upward, the movement direction of the tobacco stems is upward. During the process of transitioning from conveying tobacco stems to the wire suction belt adsorbing tobacco stems, the movement direction of the tobacco stems changes. Compared with cut tobacco, since tobacco stems are heavier, such a setting will cause the tobacco stems to be unevenly distributed and have an uncertain direction in the cut tobacco bundle on the wire suction belt, thereby resulting in a high piercing rate of cigarette rods. Piercing means that during the subsequent cigarette rod forming process, the tobacco stems will pierce the surface cigarette paper, which will affect the product quality and also cause waste of materials. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a wire suction and forming device for a cigarette making machine, so that the flow direction of tobacco stems is basically the same as that of the cut tobacco bundle, reducing the piercing rate of cigarette rods.

[0031] As Figure 1 and Figure 2 shown, the present utility model provides a wire suction and forming device for a cigarette making machine, which can be applied to PROTOS series cigarette making machines. The wire suction and forming device for the cigarette making machine includes a frame, a suction mechanism 3, at least two fluidized beds 1, at least two wire suction channels 2 and at least two wire suction belts. The at least two fluidized beds 1 are arranged at intervals on the frame; the fluidized bed 1 is used for conveying cut tobacco stems 100; the at least two wire suction channels 2 are arranged in one-to-one correspondence with the at least two fluidized beds 1; the wire outlet of the fluidized bed 1 is communicated with the wire inlet of the wire suction channel 2. The wire suction channel 2 is arranged in the vertical direction, and a contact member 4 is provided on the inner side wall at the wire inlet. The contact member 4 extends along a first direction, and the bottom wall of the contact member 4 can be in contact with the tobacco stems in the cut tobacco stems 100; the first direction is perpendicular to the vertical direction; the at least two wire suction belts are arranged in one-to-one correspondence with the at least two wire suction channels 2; the wire suction belt is arranged in the wire suction channel 2, and the wire suction belt is arranged at an interval from the contact member 4 and is located on the side of the contact member 4 away from the fluidized bed 1; the wire suction belt is used for adsorbing the cut tobacco stems 100 and can move the cut tobacco stems 100 along the first direction; the suction mechanism 3 is used for negative pressure suction; the at least two wire suction channels 2 are arranged at the suction port of the suction mechanism 3. During operation, when the cut tobacco stems 100 are moved to the wire inlet of the wire suction channel 2 by the conveying of the fluidized bed 1 and the negative pressure suction of the suction mechanism 3, the tobacco stems are in contact with the contact member 4. Since the contact member 4 extends along the first direction, the contact member 4 changes the movement direction of the tobacco stems, making the movement direction of the tobacco stems basically the same as the first direction, which is the movement direction of the cut tobacco stem bundle, so that the disordered tobacco stems are rearranged, and the piercing rate of the cigarette can be reduced. Specifically, as Figure 1As shown in the figure, after the tobacco stem abuts against the abutting member 4, the long side direction of the tobacco stem is parallel to the first direction. The fluidized bed 1 and the air suction mechanism 3 continue to convey the tobacco stem, and the tobacco stem moves upward through the gap on the right side of the abutting member 4. During the upward movement, the long side direction of the tobacco stem is basically parallel to the first direction. Then, the suction belt drives the tobacco stem and the cut stem bundle to move along the first direction, thereby completing the suction filament forming process. By only setting the abutting member 4, the movement direction of the tobacco stem can be changed, with a simple structure and low cost. Through the combined action of the fluidized bed 1 and the air suction mechanism 3, the conveying efficiency of the cut stem 100 can be improved. By providing at least two fluidized beds 1, suction channels 2, and suction belts, and corresponding them respectively, the production efficiency of cigarettes can be improved.
[0032] Optionally, in this embodiment, in one suction channel 2, there is one abutting member 4, and the abutting member 4 is arranged on the inner wall of one side at the wire inlet of the suction channel 2. With such a setting, while changing the movement direction of the tobacco stem, the structure is simple and the cost is relatively low. Optionally, in this embodiment, a chamfer is provided at the outer edge of the inner wall on the other side at the wire inlet of the suction channel 2. By providing the chamfer, it is convenient for the cut stem 100 to enter the suction channel 2. In other embodiments, in one suction channel 2, there are two abutting members 4, and the two abutting members 4 are respectively arranged on the inner walls on both sides at the wire inlet of the suction channel 2, and there is a gap between the two abutting members 4. When the fluidized bed 1 and the air suction mechanism 3 convey the tobacco stem, multiple tobacco stems can contact any one of the abutting members 4, which is more conducive to reducing the piercing rate of cigarettes.
[0033] To ensure that all the tobacco stems conveyed from the fluidized bed 1 to the suction channel 2 abut against the abutting member 4 and the directions of the tobacco stems are changed, the length of the abutting member 4 extending along the first direction is equal to the length of the wire outlet of the fluidized bed 1 extending along the first direction.
[0034] Optionally, in this embodiment, the abutting member 4 has a cuboid structure. With such a setting, the processing is simple. Optionally, in this embodiment, the length of the first side line 41 of the abutting member 4 along the first direction is 560 mm, the length of the second side line 42 of the abutting member 4 is 0.8 mm; the length of the third side line 43 of the abutting member 4 is 2.5 mm. The length of the third side line 43 of the abutting member 4 is 2.5 mm, and the length of the third side line 43 of the abutting member 4 is greater than the length of the second side line 42. When the tobacco stem moves upward after abutting, the side wall of the abutting member 4 can play a better guiding role. The length of the second side line 42 of the abutting member 4 is 0.8 mm, which reduces the deposition of the tobacco stem at the bottom of the abutting member 4. In addition, the abutting member 4 can be made of a flexible material, which can reduce the damage to the tobacco stem during the movement of the tobacco stem.
[0035] Optionally, in this embodiment, the wire suction forming device of the cigarette making machine further includes a channel forming assembly. The channel forming assembly is arranged at the air suction port of the air suction mechanism 3 and is used to form at least two wire suction channels 2; the abutting member 4 is integrally arranged with the channel forming assembly. Integrally arranging the abutting member 4 and the channel forming assembly can prevent the abutting member 4 from falling off and damaging the device. In other embodiments, the abutting member 4 is detachably connected to the channel forming assembly, as long as it can achieve that when the fluidized bed 1 and the air suction mechanism 3 convey the cut tobacco 100 to the wire inlet of the wire suction channel 2, the cut tobacco abuts against the abutting member 4 to change the movement direction of the cut tobacco, and this embodiment is not limiting.
[0036] Optionally, in this embodiment, the wire suction forming device of the cigarette making machine further includes a channel forming assembly. The channel forming assembly includes three wire suction guide rails 5. The three wire suction guide rails 5 are sequentially arranged at intervals at the air suction port of the air suction mechanism 3 to form two wire suction channels 2. With this arrangement, while saving costs, the production efficiency of cigarette sticks can be improved.
[0037] Optionally, in this embodiment, the wire suction forming device of the cigarette making machine further includes a wire suction belt guide rail 6. The wire suction belt guide rail 6 is fixed between two adjacent wire suction guide rails 5, and the wire suction belt is slidably connected to the wire suction belt guide rail 6. By providing the wire suction belt guide rail 6, when the wire suction belt moves in the first direction, the wire suction belt guide rail 6 guides the movement of the wire suction belt.
[0038] In addition, the wire suction forming device of the cigarette making machine further includes a fastener. Among two adjacent wire suction guide rails 5, the fastener sequentially passes through one of the wire suction guide rails 5 and a wire suction belt guide rail 6 and is threadedly connected to the other wire suction guide rail 5. While fixing the wire suction belt guide rail 6 between the two wire suction guide rails 5, the fixed connection between two adjacent wire suction guide rails 5 is realized. In other embodiments, the wire suction belt guide rail 6 can be fixed between the two wire suction guide rails 5 by means of clamping, welding or bonding.
[0039] Optionally, in this embodiment, both the wire suction belt guide rail 6 and the wire suction belt are of a mesh structure. When the air suction mechanism 3 sucks air under negative pressure, a connected air channel is formed to adsorb the cut tobacco 100 on the wire suction belt. Optionally, in this embodiment, the fluidized bed 1 and the air suction mechanism 3 are mature technologies in the relevant field, and this embodiment will not elaborate on them.
[0040] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
