[0018] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0019] In view of the problems existing in the high-flow finished tobacco packaging equipment, this embodiment provides a tobacco packaging system. Figure 1 As shown, the tobacco packing system includes a cigarette box conveyor line 1 composed of a plurality of conveyors, and is arranged with a packing station A and a packing station B on the cigarette box conveyor line 1; a closed transverse tobacco conveyor 2 is provided between the packing station A and the packing station B, and the middle of the closed transverse tobacco conveyor 2 is connected with the closed longitudinal tobacco conveyor 3.

[0020] Among them, both packing station A and packing station B are equipped with equipment outer frame 4 and equipment inner frame 5, the equipment outer frame 4 is placed on the ground, and the equipment inner frame 5 is placed inside the equipment outer frame 4 through a weighing mechanism 6. The equipment inner frame 5 is sequentially installed with a feed hopper 7 connected with a horizontal tobacco conveyor, a box lifting mechanism 8 located at the outlet of the feed hopper 7 and capable of vertical movement and connection with a cigarette box, and a cigarette box located in the equipment inner frame 5 and on the cigarette box conveyor line 1.

[0021] The following is a detailed description of the structure and function of each component of the tobacco packing system: Cigarette box conveyor line 1: Figure 1 As shown, the function of the cigarette box conveyor line 1 is to convey empty cigarette boxes and full cigarette boxes after tobacco is packed, and at the same time, the empty cigarette boxes and full cigarette boxes are stopped at each station to cooperate with the tobacco packing work. The several conveyors of the cigarette box conveyor line 1 include two conveyors installed at the bottom of the internal frame 5 of the equipment, and two conveyors located between the packing station A and the packing station B.

[0022] Closed longitudinal tobacco conveyor 3 and closed transverse tobacco conveyor 2: Figure 2 As shown, the closed longitudinal tobacco conveyor 3 is used for longitudinal conveying of tobacco, and comprises a conveyor and a first closed cover 9 installed on the upper part of the conveyor. The first closed cover 9 can close the conveyor to prevent dust and dust overflow during the conveying of tobacco. Figure 1As shown, the closed transverse tobacco conveyor 2 is used for transverse conveyance of tobacco. By running the closed transverse tobacco conveyor 2 clockwise or counterclockwise, the tobacco can be conveyed to the packing station A or the packing station B to achieve continuous packing of tobacco. The closed transverse tobacco conveyor 2 includes a conveyor and a second closed cover 10 installed on the upper part of the conveyor. The second closed cover 10 can close the conveyor to prevent dust and dust overflow during the tobacco conveying process. The closed longitudinal tobacco conveyor 3 extends into the second closed cover 10 of the transverse tobacco conveyor to completely seal the tobacco conveying process. Figure 2 As shown, in addition, in order to avoid the accumulation of tobacco on the closed longitudinal tobacco conveyor 3 when it is transferred to the closed transverse tobacco conveyor 2, a first material transfer mechanism 11 is further provided at the connection between the closed transverse tobacco conveyor 2 and the closed longitudinal tobacco conveyor 3 in this embodiment.

[0023] Feed hopper 7: Figure 1 As shown, the feed hopper 7 is a box structure with one side and the bottom open. The feed hopper 7 is connected to the two ends of the closed transverse tobacco conveyor through the feed port on the side, and its bottom discharge port is connected to the cigarette box through the box lifting mechanism 8. The feed hopper 7 can receive the tobacco conveyed by the closed transverse tobacco conveyor 2 and transfer it to the cigarette box. In order to avoid the accumulation of tobacco after the tobacco falls through the feed hopper 7, as shown in FIG. Figure 1 As shown, in this embodiment, a second material shifting mechanism 12 is installed at the upper part of the outer frame 4 of the equipment, and the second material shifting mechanism 12 extends into the feed hopper 7.

[0024] Box lifting mechanism 8: Figure 1 As shown, the box lifting mechanism 8 is used to connect the discharge port of the feed hopper 7 with the top opening of the cigarette box. Figure 3 and Figure 4 As shown, the casing lifting mechanism 8 includes an upper fixed rectangular tube 22 fixedly installed at the outlet of the feed hopper 7, a driving power source 23 symmetrically arranged on both sides of the upper fixed rectangular tube 22 and installed on the inner frame 5 of the equipment through a fixed seat, and a sliding interface rectangular tube 24 sleeved on the upper fixed rectangular tube 22 is installed at the output end of the driving power source 23. Further, considering the sealing problem, as Figure 4 As shown, in this embodiment, an upper sealing protection 25 cooperating with the upper fixed rectangular tube 22 is provided above the sliding interface rectangular tube 24, a slope interface cooperating with the top opening of the smoke box is provided below the sliding interface rectangular tube 24, and a lower sealing protection 26 cooperating with the smoke box is provided at the slope interface.

[0025] Weighing mechanism 6: Figure 1 As shown, the weighing mechanism 6 includes weighing sensors installed at the four corners of the bottom of the inner frame 5 of the equipment, which are used to weigh the tobacco boxes so that the weight of the tobacco in each cigarette box is uniform, ensuring the standardization of the tobacco loaded in each cigarette box.

[0026] Based on the above tobacco packing system, its working principle is as follows: First, if Figure 1 As shown, the conveyor of the cigarette box conveyor line 1 conveys the empty cigarette box to the packing station A and the packing station B; then, the box lifting mechanism 8 is activated, and the sliding interface rectangular tube 24 driven by the power source 23 of the box lifting mechanism 8 moves downward and pairs with the top opening of the cigarette box; at this time, the closed longitudinal tobacco conveyor 3, the closed transverse tobacco conveyor 2, the feed hopper 7, the box lifting mechanism 8, and the cigarette box are in a sealed and connected state to prevent dust and dust overflow during the tobacco packing process. Start the closed longitudinal tobacco conveyor 3 and the closed transverse tobacco conveyor 2, and the tobacco is evenly distributed to the closed transverse tobacco conveyor 2 by the closed longitudinal tobacco conveyor 3 through the first material shifting mechanism 11, and then transported to the feed hopper 7 on either side by the closed transverse tobacco conveyor 2. After entering the feed hopper 7, the tobacco is dropped into the cigarette box through the box lifting mechanism 8; at the same time, the second material shifting mechanism 12 in the feed hopper 7 ensures that the tobacco is evenly spread to prevent the tobacco from piling up at any position in the cigarette box. During the tobacco packing process, the weighing sensors at the four corners of the bottom of the inner frame weigh the static conveyor at the bottom of the inner frame, the tobacco box and the tobacco in the box, the static box lifting mechanism 8, and the feed hopper 7 in real time, avoiding the influence of the moving parts on the weighing, basically maintaining static weighing, and making the weighing measurement accurate.

[0027] When the tobacco is packed at packing station A, the box lifting mechanism 8 drives the sliding interface rectangular tube 24 driven by the power source 23 to move upward and separate from the top opening of the cigarette box; at the same time, the closed transverse tobacco conveyor 2 runs in the opposite direction to pack the tobacco at packing station B. Then, the full cigarette box leaves the packing station A and waits for the tobacco to be packed at the packing station B to be transported to the next process together; at the same time, the new empty cigarette box is transported to the packing station A to wait for the tobacco to be packed, so as to realize the continuity of tobacco packing and complete the high-efficiency and fully automated tobacco packing.

[0028] Further, as a preferred technical solution of this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the first material-dispensing mechanism 11 and the second material-dispensing mechanism 12 in this embodiment have similar structures, and both include a material-dispensing power source, a driving shaft, a driving rod, and a material-dispensing plate. The driving shaft 14 of the first material-dispensing mechanism is rotatably mounted on the closed cover of the closed transverse tobacco conveyor 2 through a bearing seat; the driving shaft 18 of the second material-dispensing mechanism is rotatably mounted on the equipment outer frame 4 through a bearing seat, and the driving shaft 18 of the second material-dispensing mechanism passes through the feed hopper 7. The material-dispensing power source 13 of the first material-dispensing mechanism is installed at the outer end of the closed longitudinal tobacco conveyor 3 through a mounting seat, and is connected to the driving shaft through the driving rod 15 of the first material-dispensing mechanism; the material-dispensing power source 17 of the second material-dispensing mechanism is installed on the equipment outer frame 4 through a mounting seat, and is connected to the driving shaft through the driving rod 19 of the second material-dispensing mechanism. The material-shifting plate 16 of the first material-shifting mechanism is located in the closed cover of the closed transverse tobacco conveyor 2, and one end of it is mounted on the driving shaft 14 of the first material-shifting mechanism; the material-shifting plate 20 of the second material-shifting mechanism is located in the feed hopper 7, and one end of it is mounted on the driving shaft 18 of the second material-shifting mechanism through a connecting piece.

[0029] The first material dispensing mechanism 11 and the second material dispensing mechanism 12 both drive the driving shaft to rotate through the driving rod, and the driving shaft rotates while driving the material dispensing plate to swing, thereby achieving uniform distribution of materials to the closed transverse tobacco conveyor 2, and uniform spreading of the tobacco into the cigarette box.

[0030] Further, as a preferred technical solution of this embodiment, Figure 1 As shown, in this embodiment, pipe interfaces 21 connected to the workshop dust removal system pipelines are provided at both ends of the closed cover of the closed transverse tobacco conveyor 2; the workshop dust removal system pipelines can be connected through the pipe interface 21, so as to suck out the dust and overflow dust in the tobacco packing process to prevent it from falling into the tobacco box.

[0031] In addition, as a preferred technical solution of this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a clamping cover mechanism 27 is installed between the sleeve box lifting mechanism 8 and the top opening of the smoke box on the inner side of the outer frame 4 of the device. The clamping cover mechanism 27 is an existing device structure, and its detailed structure and working principle can be found in patent document CN201922495118.7, which will not be described in detail here.

[0032] It should be noted that, in this embodiment, the driving power source 23 and the material shifting power source mentioned may be a cylinder or an electric cylinder, or a motor in conjunction with a gear rack structure to achieve corresponding actions. Example 2

[0035] Step 4, when the weight of the weighing system at packing station A reaches the set value, the transverse tobacco conveyor rotates clockwise; before the transverse tobacco conveyor rotates clockwise, the box-putting mechanism at packing station B moves to the specified position; consistent with the process of step 3, the tobacco is laid layer by layer into cigarette box I.
