Among them, the finished shredded tobacco formed by the tobacco leaves after the silk making process will be temporarily placed in the shredding cabinet, so that it can be transported to the cigarette machine for rolling. This transportation process is called wire feeding. At present, the wire feeding of cigarette enterprises mainly includes two automatic wire feeding methods besides manual wire feeding, one is wire feeding by wind force, and the other is wire feeding by rail car. Due to its clean, efficient and environmentally friendly characteristics, wind wire feeding is currently used by the vast majority of cigarette companies. Nonetheless, there are still some problems with pneumatic wire feeding, such as wire feeding uniformity and grade switching. The uniformity of wire feeding can be regarded as the difference in the quantity and quality of tobacco entering different cigarette machines during the transportation of tobacco along the pipeline; brand switching exists in the process of transporting cigarettes of different brands in the pipeline. By changing the wire feeding pipeline, it can be avoided. Mixed brand accident occurred after the tobacco was mixed.

There are currently different solutions to the above problems, such as using a rotary disc side suction wire feeder or multiple bottom suction wire feeders, setting up a grade distribution station or setting a rotary interface, and dynamically adjusting the fan frequency and damper size. However, the above solutions can only solve some problems, and once the equipment is finalized, it cannot be adjusted, and it is difficult to adapt to other problems and new problems in the production process.

To sum up, to provide a wire feeding system that can simultaneously solve the problems of wire feeding uniformity and brand switching in the production process, and can be further adjusted with production, is a problem that those skilled in the art need to solve at present.

As shown in FIG. 1 , a flexible wind-driven wire feeding device provided by the present utility model comprises wire feeding machine units 23 that are adjacent to each other, and are arranged upstream of the wire feeding machine unit 23 to provide the feed of shredded tobacco to the wire feeding unit 23 device, and an air supply duct device arranged downstream of the wire feeder unit 23 and arranged symmetrically in space to connect and connect the wire feeder unit 23 and the cigarette machine unit 3 in one-to-one correspondence. It is realized that any one of the wire feeding machine units 23 is connected with different cigarette machine units.

The above-mentioned wire feeder unit 23 is composed of at least one set of wire feeders 231, and the positions are close to each other. The number of wire feeders 231 in each group is 2 to 5. In the process of wind wire feeding, the above-mentioned wire feeding unit 23 can transport the same type of cut tobacco according to the type of cut tobacco provided by the feeding device.

It should be noted that the adjacent setting mentioned here refers to placing all the wire feeders 231 in the production site, and the wire feeders 231 placed after the wire feeders 231 can be located in the four directions of the front, rear, left, right, and right of the already placed wire feeders 231. In any direction, specifically, the arranged wire feeder unit 23 presents the effect of a matrix. By arranging the wire feeder unit 23 in this way, on the one hand, the feeding device located upstream of the wire feeder unit 23 can cover all the wire feeders 231 with a short path; on the other hand, the centrally arranged wire feeder unit 23 is Downstream thereof, the air supply duct arrangement can also be arranged in an optimal way.

The above optimal method refers to a plan formed by comprehensively considering factors such as the cost of the pipeline, the complexity of the layout, and the difficulty of switching the pipeline when arranging the air supply duct device. The centralized and symmetrical arrangement of the wire feeder unit 23 can make the layout of the whole system clear and easy to adjust the connection relationship of the pipes, and at the same time, avoid using many bends as much as possible, so as not to affect the conveying efficiency of the shredded tobacco in the pipes.

The feeding device includes a stepping belt 22 and a quantitative feeder 21 that match the number of groups of the wire feeder unit 23 . The stepping belt 22 is connected to the wire storage cabinet 1 and the wire feeding machine 231 . It should be noted that the connection mentioned here is not a single-fingered connection. Since the wire feeder 231 is located below the stepping belt 22, when a stepping belt 22 covers the wire feeding machine 231 located on the same straight line, the The shredded tobacco carried on the stepping belt 22 can also enter the feeding port of the shredding machine 231 through the quantitative feeder 21 . Therefore, as long as the stepping belt 22 covers the wire feeder 231, it can be called a connection.

In the connection of the above-mentioned feeding device, the quantitative feeder 21 is a key component to form a combination with the stepping belt 22. This combination can realize fixed-point quantitative feeding of the required shredded tobacco to the feeder 231. This feeding method is to solve the problem of feeding shredded tobacco. One of the key aspects of uniformity. Specifically, because the stepper belt 22 can control the movement of the stepper belt 22 by controlling the rotation of the stepper motor, that is, to control the position parameters, to be precise, to control which feeder 231 a certain point of the stepper belt 22 corresponds to. The quantitative feeder 21 can put different grades of cut tobacco on the stepping belt 22 and the weight is controllable. When the quantitative feeder 21 puts a certain weight of cut tobacco on the stepping belt 22, the stepping The belt 22 can move the point where the cut tobacco is placed to the predetermined feeding port of the wire feeding machine 231, so as to realize fixed-point quantitative feeding.

The air supply pipe device in the flexible wind wire feeding system provided by the present invention includes four pipelines connected end to end, that is, the first end of the first pipeline device 241 is fixedly connected to the cigarette machine 31, and the second end is connected to the second end of the pipeline device 241. The first end of the pipeline device 242 is fixedly connected, and then the second end of the second pipeline device 242 is connected to the first end of the third pipeline device 243, and the second end of the third pipeline device 243 is connected to the first end of the third pipeline device 243. The top of the four-pipeline 244 device and the bottom end of the fourth-pipeline device 244 are connected to the discharge port of the wire feeding machine 231, so as to realize the air supply duct device to connect the cigarette machine unit and the wire feeding machine unit.

In order to realize one-to-one correspondence, the first, second, third and fourth pipeline devices mentioned here are all a set of pipelines, and the number of pipelines in each group is equal to the number of cigarette machines.

The first pipeline device 241 is at least one set of pipelines whose first ends are fixedly connected to the cigarette machine unit 3 one by one, and whose second ends are fixed and unchanged. The second ends of the plurality of first pipeline devices 241 are horizontally located The same, the vertical height has a drop. For example, 1# cigarette machine corresponds to 1# first pipeline device, 2# cigarette machine corresponds to 2# first pipeline device, then the second end of 1# first pipeline device and the second end of 2# first pipeline device The XY coordinates of the ends are the same, and the Z coordinate has a height difference h1. By analogy, the XY coordinates of the second ends of the 12 first pipeline devices corresponding to the 12 cigarette machines are all the same, but the Z coordinates are different from h1, h2, h3...h1, where h1=h2=h3...= h11, that is, when the second ends of the 12 first pipeline devices are arranged equally in the height direction, the device has better installation and use performance. The first pipeline devices 241 are connected to each cigarette machine 31 one by one, so as to ensure that the pipelines are independent of each other and will not interfere with each other, and the process of setting up a brand switching station is omitted.

The second pipeline device 242 is also a group of pipelines with the same number as the first pipeline device 241 and a drop in the height direction, and the group of pipelines is inclined to the third pipeline device 243 in the same horizontal plane. The first ends of each second pipeline device 242 are fixedly connected to the second end of the first pipeline device 241 in the plane where they are located one by one at the same height, that is, the distance between the first pipeline device 241 and the second pipeline device 242 All connection points between them are fixed. For example, 1# first pipeline device is connected with 1# second pipeline device, 2# first pipeline device is connected with 2# second pipeline device... and so on. The second pipeline device 242 is arranged obliquely to the third pipeline device 243 in the horizontal plane, and the length of the second pipeline device 242 is adjusted along the direction of the inclined arrangement, so that the second pipeline device 242 can be connected to different groups of feeding threads. on the engine unit. For example, the second end of the 1# second pipeline device is extended to the coordinates (X1, Y1, Z1). By extending the 1# second pipeline device, the coordinates of the second end can be (X2, Y2, Z1) , since Y1 and Y2 correspond to different groups of wire feeders (X, Y1, Z) or (X, Y2, Z), as long as the third pipeline device 243 is further adjusted to make the X coordinates coincide, and the fourth pipeline device 244 is adjusted to make the The Z coordinate coincides, and the connection with different groups of wire feeders can be realized.

The third pipeline device 243 is also a set of pipelines with the same number as the above-mentioned two pipeline devices. The first end of the third pipeline device 243 is connected to the second end of the second pipeline device 242. In short, the third pipeline device 243 is arranged horizontally. The second line means 242 are connected. Specifically, when the coordinates of the second end of the 1# second pipeline device are (X1, Y1, Z1), and the coordinates of the second end of the 2# second pipeline device are (X2, Y2, Z2), if If the 1# third pipeline device is selected to be connected to the 1# second pipeline device, the vertical height of the plane where it is located needs to be adjusted to Z1. If it is selected to connect to the 2# second pipeline device, the plane it is located in needs to be adjusted. The vertical height to Z2.

As shown in FIG. 2 and FIG. 3 , since the third pipeline device 243 connects the second pipeline device and the fourth pipeline device, the third pipeline device 243 should be able to select the second pipeline with different heights according to the selected second pipeline device. The device 242 adjusts its height and also its length according to the position of the wire feeder. Taking the system with 12 cigarette machines and 12 air supply duct devices with adjustable paths as an example in the figure, the 12 third duct devices 243 are divided into two layers, 6 on each layer. The 6 pipelines located on the upper layer can be connected to the wire feeder on the left, or the third pipeline device can be extended and connected to the wire feeder on the right. By analogy, when multiple sets of wire feeders are set in the whole system, multiple sets of air supply pipeline devices are set accordingly, and the spatial distribution of pipelines is A×B, where A represents the number of layers, and B represents the number of parallel pipelines on the same layer. In order to connect the third pipe arrangement 243 from the wire feeder on the left to the wire feeder on the right, the third pipe arrangement 243 needs to be extended, ie the length is variable.

The fourth pipeline device for connecting the third pipeline device 243 with different wire feeders in height is arranged vertically, so that it can be connected to the third pipeline device 243 by adjusting the length of the fourth pipeline device , so that its length varies with the height of the third piping device 243 .
