Technical Field
[0001] The present application relates to the technical field of cigarette making equipment, and in particular to a metering tobacco feeding system. Background Art
[0002] At present, most manufacturers generally use wind-powered wire feeding systems to supply tobacco to cigarette making machines. The cigarette making machine suction box is a device that separates the upstream tobacco from the suction negative pressure wind. According to the cigarette making machine hopper material request signal, the lower flap door is opened and the tobacco falls into the hopper to ensure the production material of the cigarette making machine.
[0003] In the actual production process of cigarette factories, due to the loss of moisture in tobacco during wind conveying, the tobacco powder in the tobacco is sucked away by negative pressure wind. That is, the consumption of tobacco in the process of wind conveying cannot be verified, which means that the accurate assessment of the tobacco consumption index of a single box of tobacco in the rolling unit cannot be achieved.
[0004] It can be seen that the current cigarette making machines have built-in tobacco suction boxes without tobacco weighing function. In order to achieve the purpose of evaluating the tobacco consumption of a single box produced by the cigarette making machine, some manufacturers have modified the internal tobacco suction boxes of cigarette making machines and added weighing sensors to achieve tobacco weighing and measuring. In actual use, due to the internal modification of the cigarette making machine, local space restrictions and high failure rate, maintenance is difficult; the weighing sensor is easily disturbed by the outside world and becomes unstable, and the weighing accuracy of the tobacco suction box cannot be guaranteed.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0030] Please refer to Figures 1 to 3 This embodiment provides a metering tobacco feeding system, which includes a metering tobacco feeder 1 and a static weighing tobacco collection box 15 connected in sequence, wherein the static weighing tobacco collection box 15 is used to be connected to a cigarette making machine 2.
[0031] For details, please refer to Figure 1 The metering wire feeder 1 is connected in sequence to a bidirectional material distribution belt conveyor 11, a material distribution trousers pipe 12, a weighing and metering hopper 13 and a single-tube storage bin type wire feeder 14.
[0032] The bidirectional material distribution belt conveyor 11 includes a belt that can run forward and backward to transport shredded tobacco into two pipes of the material distribution trousers pipe 12. The two pipes of the material distribution trousers pipe 12 are respectively equipped with weighing and metering hoppers 13.
[0033] The weighing and metering hopper 13 includes a first hopper and a first photoelectric switch, a first platform scale, and a first flap installed in the first hopper. The first platform scale is used to detect the weight of the tobacco in the first hopper. The first platform scale has excellent electromagnetic compatibility and anti-interference performance, high weighing accuracy, and accurate tobacco weight measurement. The first photoelectric switch is used to send a first material request signal when the weight of the tobacco in the first hopper does not reach the first preset weight. The bidirectional material dividing belt conveyor 11 conveys the tobacco to the weighing and metering hopper 13 through the material dividing trousers pipe 12 according to the first material request signal until the weight of the tobacco in the first hopper reaches the first preset weight. The bidirectional material dividing belt conveyor 11 stops conveying tobacco to the weighing and metering hopper 13. The first preset weight is determined according to the tobacco consumption of the cigarette making machine 2, and is also used to achieve the index assessment of the tobacco consumption of the cigarette making machine 2 on the same day; the tobacco in the weighing and metering hopper 13 passes through the single-tube storage-type tobacco feeder 14 and the static weighing type tobacco collection box 15 in sequence to reach the cigarette making machine 2.
[0034] Please refer to Figure 2 The single-tube storage bin type wire feeder 14 includes a storage bin 141, a conveying bottom belt 142, a uniform material loosening roller 143, a wire feeding bucket 144 and a horizontal wire suction pipe 145. The bidirectional material distribution belt conveyor 11, the material distribution trousers pipe 12, the weighing and metering hopper 13 and the single-tube storage bin type wire feeder 14 are connected in sequence from top to bottom.
[0035] The storage bin 141 is connected to the bottom of the weighing and metering hopper 13. The storage bin 141 stores a certain amount of tobacco to ensure timely supply of tobacco required by the cigarette making machine 2. The conveying bottom belt 142 and the uniform loosening roller 143 are installed inside the storage bin 141. The wire feeding hopper 144 is installed at the bottom of the storage bin 141. The wire feeding hopper 144 is connected to the static weighing type wire collection box 15 through the horizontal wire suction tube 145. The conveying bottom belt 142 supplies a corresponding amount of tobacco to the wire feeding hopper 144 according to the wire suction signal of the cigarette making machine 2. The wire suction signal of the cigarette making machine 2 can be determined according to the negative pressure signal measured by the negative pressure switch in the horizontal wire suction tube 145. If there is a negative pressure signal, it means that tobacco needs to be supplied to the horizontal wire suction tube 145, and the conveying bottom belt 142 needs to transport tobacco to the horizontal wire suction tube 145, thereby realizing automatic adjustment of the wire supply amount.
[0036] The input end of the conveyor belt 142 is lower than the output end of the conveyor belt 142, and the uniform loose roller 143 is installed at the output end of the conveyor belt 142. In this way, the conveyor belt 142 can accurately control the amount of tobacco shreds transported backwards, and prevent the tobacco shreds from flowing too much to the shred feeding hopper 144 due to their own gravity and the inertia of falling from the weighing and metering hopper 13. A scraper device is also installed on the conveyor belt 142 to clean the tobacco shreds on the conveyor belt 142 in time.
[0037] A second photoelectric switch is installed in the wire feeding hopper 144. The second photoelectric switch is used to send a pause signal to the conveyor bottom belt 142 when it detects excessive tobacco in the wire feeding hopper 144, so as to ensure that the wire feeding hopper 144 is not blocked.
[0038] The metering tobacco feeding system also includes a negative pressure suction device, which is connected to one side of the static weighing type wire collection box 15. The negative pressure suction device is used to extract air from the static weighing type wire collection box 15 and the metering wire feeder 1, so as to form air that flows in the metering wire feeder 1 and the static weighing type wire collection box 15 in sequence, thereby promoting the transportation of tobacco. The air flow rate can range from 15m / s to 18m / s, which can be adjusted according to the distance between the cigarette making machine 2 and the metering wire feeder 1 to ensure the supply of tobacco to the cigarette making machine 2 and the process performance of the tobacco after transportation.
[0039] Please refer to Figure 3 The static weighing type wire collection box 15 includes a wire storage bin 151, a second hopper 152 and a material receiving chute 153 which are connected in sequence; the wire storage bin 151, the second hopper 152 and the material receiving chute 153 are connected in sequence from top to bottom.
[0040] Among them, the second hopper 152 is equipped with a third photoelectric switch, a second platform scale, and a second flap. The second platform scale is used to detect the weight of the tobacco in the second hopper 152. The third photoelectric switch is used to send a second material request signal when the weight of the tobacco in the second hopper 152 does not reach the second preset weight. The tobacco storage bin 151 conveys the tobacco to the second hopper 152 according to the second material request signal until the weight of the tobacco in the second hopper 152 reaches the second preset weight; the tobacco in the second hopper 152 passes through the material receiving slide 153 to reach the cigarette making machine 2.
[0041] The tobacco stor- ing bin 151 receives tobacco shreds delivered by negative pressure air from upstream, and after being weighed by the second platform scale, it falls into the tobacco scavenging box of the cigarette making machine 2 through the material receiving chute 153, thereby ensuring the supply of tobacco shreds produced by the cigarette making machine 2. In this way, the static weighing type tobacco stor- ing box 15 adopts static weighing technology, which can achieve the purpose of evaluating the tobacco shreds consumption per box produced by the cigarette making machine 2.
[0042] The beneficial effects of the metering tobacco feeding system provided in this embodiment include:
[0043] 1. The metering tobacco feeding system combines the metering tobacco feeder 1 and the static weighing tobacco collection box 15. First, the metering tobacco feeder 1 is used to statically weigh the tobacco before air delivery. Then, the static weighing tobacco collection box 15 is configured on the tobacco collection box of the rolling and splicing unit in the rolling workshop. The tobacco weighed by the static weighing tobacco collection box 15 slides into the rolling and splicing machine through the material receiving slide 153, thereby realizing the assessment of the tobacco single box consumption index of the rolling and splicing unit.
[0044] 2. Each single-tube storage-type tobacco feeder 14 corresponds to an independent tobacco rolling and connecting unit. During the entire distribution process, the tobacco is not layered, blocked, or broken, and the tobacco weighing and measurement and the full-formula distribution and transportation are truly realized. During the tobacco feeding process, the tobacco is not thrown, vibrated, or rolled, and the tobacco structure is not changed. The equipment has a very low tobacco breaking rate.
[0045] 3. The static weighing type wire collection box 15 is completely separated from the cigarette making machine 2 and installed above the built-in wire suction box of the cigarette making machine 2. The built-in wire suction box window of the cigarette making machine 2 is transformed into a material receiving chute 153. The static weighing type wire collection box 15 adopts a full digital platform scale and a soft connection with the material receiving chute 153 to control the accurate measurement of the weight of the tobacco and realize the indicator assessment of the production of a single box of tobacco by the cigarette making machine 2.
[0046] 4. The metering wire feeder 1 and the static weighing wire collection box 15 adopt a fully enclosed structure design, which has the advantages of low wire feeding wind speed, large wire feeding amount, and clean environment.
[0047] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.
[0048] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
