The material enters the chassis 110 from the feed port 120, falls on the sliding plate 123, and is transported to the material transport chute 124 along the sliding plate 123. During the process of the material falling from the feed port 120 to the material transport chute 124, Materials can be evacuated, which is conducive to the subsequent orderly arrangement and transportation of materials.

The feed inlet 120 is provided with a cover 121 and a blower 122 with adjustable air pressure. The cover 121 of the feed port 120 can make the feed port 120 in a certain closed state. The blower 122 blows the materials in the feed port 120 so that the materials in the feed port 120 are blown up. Depending on the weight of the materials, the material The falling speeds are different, thereby forming stratified sedimentation and falling on the cover plate 121 of the feed port 120. When feeding, by opening the cover plate 121, heavier materials can fall first.

In this embodiment, please refer to Figures 1 and 2 in conjunction. The chassis 110 is also provided with a star roller 125 for loosening materials and removing impurities. The star roller 125 is disposed between the sliding plate 123 and the material transport chute 124. 125 can remove the hemp rope in the strip material, and at the same time, the star roller 125 can further disperse the strip material. Specifically, the star roller 125 includes a first end 1251 and a second end 1252 along its length direction. The surface of the pentagonal body of the star roller 125 is provided with a plurality of first teeth 1253 from the first end 1251 to the middle position. The distance between the teeth 1253 and the middle part of the star roller 125 gradually decreases from the first end 1251 to the second end 1252. The prismless surface of the star roller 125 is provided with a plurality of second teeth 1254 from the middle to the second end 1252. The distance between the second tooth 1254 and the middle part of the star roller 125 gradually increases from the first end 1251 to the second end 1252. In this embodiment, by arranging the first teeth 1253 and the second teeth 1254 in a "herringbone" shape, the insertion and dispersion effect of the star roller 125 on the jumping materials can be enhanced, so that the strip materials can loosely fall to the transport chute. Within 124.

The discharge channel 140 is located at the top of the chassis 110 and extends from the top to the bottom. The material transport mechanism 130 includes a transport belt 131 and a negative pressure adsorption member 132 located inside the transport belt 131. The working pressure of the negative pressure adsorption member 132 can be as high as The strip material is adsorbed to the surface of the conveying belt 131. In this embodiment, for example, the working pressure of the negative pressure adsorption member 132 is 0.05-0.06MPa, and the conveying belt 131 is provided with multiple meshes (not shown in the figure). ), the adsorption force formed by the negative pressure can act on the strip material on the surface of the conveyor belt 131 through the mesh. The conveyor belt 131 extends from the conveyor chute 124 in the direction near the top of the discharge channel 140 and is transported upward. The belt 131 adsorbs strip materials to the surface of the conveyor belt 131 through the negative pressure adsorption member 132, thereby reducing the possibility of crushing. At the same time, the mesh can also play a role in screening out small impurities (such as removing impurities, dust, debris, etc.), so that the broken small particles or impurities in the strip material fall directly and do not continue to be transported. .

In this embodiment, the material is fed from the top, and the conveying belt 131 starts to be transported from the bottom, so that the material is fully dispersed in the process from feeding to conveying. At the same time, the conveying belt 131 is adsorbed by negative pressure and can transport the strips The material is closely attached to the surface of the transport belt 131, effectively preventing the strip material from bouncing and falling during transportation.

The surface of the material conveying belt 131 is provided with a plurality of spaced apart material conveying baffles 134 along its length direction. The material conveying baffles 134 are arranged obliquely on the material conveying belt 131 along the direction from the feed end to the discharge end. In this embodiment, by arranging the material conveying baffle 134 on the surface of the material conveying belt 131, it can prevent the material from falling during the inclined upward movement. At the same time, the setting of the material conveying baffle 134 can reduce the negative pressure, thereby effectively Prevent excessive negative pressure from causing the material to break and be sucked into the conveyor belt 131.

The material rises obliquely from the bottom to the top. The conveying mechanism 130 is provided with vertical and side-by-side conveying rollers 135 near the top of the discharging channel 140 so that the conveying belt 131 discharges the material in a vertical direction. Due to the movement of the conveying belt 131 One end is in a vertical state. When the strip material moves to the top of the conveyor belt 131, it breaks away from the adsorption effect of the negative pressure and falls vertically downward due to its own gravity.

The chassis 110 is also provided with an opposite first loosening wheel 141 and a second loosening wheel 142 located below the discharging channel 140. The movement directions of the first loosening wheel 141 and the second loosening wheel 142 are opposite. The drum diameter is larger than the drum diameter of the second loosening wheel 142 , and the number of teeth of the first loosening wheel 141 is 5-7 times that of the second loosening wheel 142 . The first loosening wheel 141 and the second loosening wheel 142 can further convey the materials discharged from the discharge channel 140 so that they can be discharged in a better orderly and loose manner.

Furthermore, in order to further determine the thickness of the material entering the first loosening wheel 141 and the second loosening wheel 142, in this embodiment, a material guide plate 143 is also provided at the end of the discharge channel 140, and the material guide plate 143 is provided at the third Above a loosening wheel 141 and a second loosening wheel 142 . The guide plate 143 further reduces the diameter of the discharge channel 140, so that a small amount of strip material is discharged from the guide plate 143 and the discharge channel 140, and enters the first loosening wheel 141 and the second loosening wheel 142.

In this embodiment, the first loosening wheel 141 and the second loosening wheel 142 move toward each other to transport strip materials. At the same time, the diameter of the first loosening wheel 141 is larger and can play the role of carrying strip materials. The number of teeth of the first loosening wheel 141 is much greater than that of the second loosening wheel 142, which enables the strip material carried on the first loosening wheel 141 to be further evacuated under the action of the second loosening wheel 142, and the loosening effect is Better.

Further, an impurity removal assembly 144 is provided in the above-mentioned discharge channel 140. The impurity removal assembly 144 is located above the guide plate 143. The impurity removal assembly 144 includes a first screen 145, a second screen 146 and a filter for absorbing impurities. The exhaust fan 147, the first screen 145 and the second screen 146 are overlapped and can move each other, the first screen 145 is located above the second screen 146, the exhaust fan 147 is connected to the chassis 110 and is located on the second screen below 146. In order to enhance the separation of strip materials and impurities, a vibration mechanism (not shown) can also be provided on the first screen 145 . In this embodiment, the apertures of the first screen 145 and the second screen 146 may be the same or different, but they must be able to pass strip materials. The first screen 145 and the second screen 146 can move to each other, so that The sieve holes between the first screen 145 and the second screen 146 are partially overlapped, thereby reducing the sieve holes. At this time, the material cannot fall, and the impurities in the material fall from the overlapping sieve holes and are passed through the exhaust fan. 147 is sucked away. After the impurities are eliminated, the relative positions of the first screen 145 and the second screen 146 can be changed so that the strip materials can be discharged from the screen holes.

In addition, an embodiment of the present invention also provides a cigarette system, which includes the above-mentioned strip material orderly feeding device 100.

The working principle of the strip material orderly feeding device 100 is: the material enters from the feed port 120 at the top, slides down to the discharge chute at the bottom through the sliding plate 123, and during the sliding process, the material can pass through the star roller 125 of decluttering and loosening. The material falling into the discharge chute moves upward obliquely under the driving of the material conveying belt 131. The material is tightly adsorbed on the surface of the material conveying belt 131 through the action of the negative pressure adsorption member 132, which enables the material to be output in an orderly manner. When reaching the discharging channel 140, since there is no negative pressure adsorption and the conveying belt 131 is in a vertical state, the material falls vertically under its own gravity and is further loosened by the first loosening wheel 141 and the second loosening wheel 142, so that the material Orderly output in a better and looser state.

To sum up, in the strip material orderly feeding device 100 provided by the embodiment of the present invention, the materials in the transport chute 124 are loosened to the discharge channel 140 through the inclined upward transport belt 131, and the materials are in the negative pressure adsorption member 132 is close to the surface of the conveyor belt 131 under the negative pressure adsorption. Under the negative pressure adsorption, the material will not bounce and fall during transportation, effectively avoiding the occurrence of material crushing. At the same time, the material passes through the adsorbed The method is attached to the surface of the conveyor belt 131, which effectively avoids the accumulation of multiple layers of materials, and further reduces the possibility that the filamentary materials located on the upper layer of the accumulation are easily cut by the weight control device and become broken.
