Description

Technical Field

[0001] This utility model belongs to the field of tobacco production technology, and specifically relates to a tobacco packing system. Background Technology

[0002] The general process of packing tobacco shreds is as follows: empty boxes are conveyed to the tobacco packing machine via a conveyor belt, then the tobacco is fed into the boxes through pipes. After weighing, the boxes are sealed, and then a vacuum is applied to the inside of the boxes for easy storage. Finally, the boxes are transported to the warehouse for storage. Because existing workshops produce more than one type of tobacco shreds, and each workshop has multiple production lines, cross-contamination of flavors can occur during the packing process, affecting the quality of the tobacco shreds.

[0003] Therefore, a tobacco packing system is needed. Utility Model Content

[0004] The purpose of this invention is to provide a tobacco shred packaging system, thereby overcoming the shortcomings of existing tobacco shred packaging methods where the simultaneous production of multiple types of tobacco leads to flavor mixing and a decline in tobacco quality. The specific technical solution is as follows:

[0005] A tobacco packing system includes a conveyor belt and a tobacco packing machine. The conveyor belt passes through the tobacco packing machine. The system also includes a first lifting door, a second lifting door, a third lifting door, a fourth lifting door, a first channel, and a second channel. The first and second channels are respectively installed on both sides of the tobacco packing machine and are connected to it. The first lifting door is installed at the end of the first channel away from the tobacco packing machine. The second lifting door is installed at the end of the first channel close to the tobacco packing machine. The third lifting door is installed at the end of the second channel close to the tobacco packing machine. The fourth lifting door is installed at the end of the second channel away from the tobacco packing machine. The first lifting door, the second lifting door, and the first channel form a preparation chamber. The second lifting door, the third lifting door, and the tobacco packing machine form a packing chamber. The third lifting door, the fourth lifting door, and the second channel form a vacuum chamber. The conveyor belt passes sequentially through the preparation chamber, the packing chamber, and the vacuum chamber.

[0006] Preferably, a partition is installed on the side wall of the tobacco packing machine, which encloses the working area of ​​the tobacco packing machine. The partition has an opening for connecting with the first channel and the second channel.

[0007] Preferably, air intake ports are provided on the inner sidewalls of the first channel, the second channel, and the partition. The air intake ports are arranged vertically symmetrically about the center of the first channel and the second channel, and air intake pipes are connected to the air intake ports.

[0008] Preferably, the first, second, third, and fourth lifting doors have the same structure. The first lifting door includes a door panel, a hydraulic cylinder, a storage box, and a sealing strip. A through hole is provided at the top of the first passage. The storage box is vertically installed at the top of the first passage and communicates with the through hole. The door panel is slidably installed inside the storage box. The hydraulic cylinder is installed on the side of the storage box away from the first passage. The moving end of the hydraulic cylinder is connected to the door panel. A sealing strip is installed on the side wall of the door panel near the inner side wall of the first passage.

[0009] Preferably, the sections of the conveyor belt in the preparation chamber, packing chamber, and vacuum chamber can operate independently.

[0010] Compared with existing technologies, this utility model has the following beneficial effects:

[0011] This invention encloses the tobacco packing machine to prevent odors from spreading during packing. Simultaneously, a first and second channel are installed on both sides of the machine, forming a preparation chamber, a packing chamber, and a vacuum chamber. The boxes enter each chamber through these channels. The lifting doors of all chambers are not opened simultaneously. This isolation of multiple chambers prevents odor escape during box replacement. Furthermore, air intakes connected to suction pipes are provided within the chambers to change the gas flow direction, preventing odors from escaping through gaps in the conveyor belt. Ultimately, this ensures that no flavor transfer occurs during the packing process, guaranteeing the quality of the tobacco. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Next, refer to Figure 1 The working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0018] A tobacco packing system includes a conveyor belt 1 and a tobacco packing machine 2. The conveyor belt 1 passes through the tobacco packing machine 2 and is used to drive the box 9 forward. The tobacco packing machine 2 is used to pack the tobacco into the empty box 9, and to seal and vacuum it to facilitate the storage of the tobacco in the box 9.

[0019] One end of the first channel 7 is bolted to one side of the tobacco packing machine 2 and is connected to the tobacco packing machine 2. One end of the second channel 8 is bolted to the side of the tobacco packing machine 2 away from the first channel 7 and is connected to the tobacco packing machine 2. Both the first channel 7 and the second channel 8 are located on the conveyor belt 1, so the box 9 needs to pass through the first channel 7, the tobacco packing machine 2 and the second channel 8 in sequence.

[0020] The first lifting door 3 is installed at the end of the first channel 7 away from the tobacco packing machine 2; the second lifting door 4 is installed at the end of the first channel 7 near the tobacco packing machine 2; the third lifting door 5 is installed at the end of the second channel 8 near the tobacco packing machine 2; and the fourth lifting door 6 is installed at the end of the second channel 8 away from the tobacco packing machine 2. The space enclosed by the first lifting door 3, the second lifting door 4, and the first channel 7 forms a preparation chamber 10; the space enclosed by the second lifting door 4, the third lifting door 5, and the tobacco packing machine 2 forms a packing chamber 11; and the space enclosed by the third lifting door 5, the fourth lifting door 6, and the second channel 8 forms a vacuum chamber 12. The vacuuming component of the tobacco packing machine 2 is located inside the vacuum chamber 12. The conveyor belt 1 passes sequentially through the preparation chamber 10, the packing chamber 11, and the vacuum chamber 12. A partition is bolted to the side wall of the tobacco packing machine 2, enclosing the working area of ​​the tobacco packing machine 2. The partition has openings for connecting to the first channel 7 and the second channel 8.

[0021] The box 9 is surrounded by three chambers. When the tobacco packing machine 2 packs the box 9, the odor produced by the tobacco discharged from the feeding mechanism is difficult to dissipate, thereby reducing the impact of cross-contamination of other tobacco.

[0022] Air inlets 13 are provided on the inner walls of the first channel 7, the second channel 8, and the partition. Air inlets 13 are connected to air inlets 13. Since the first channel 7, the second channel 8, the tobacco packing machine 2, and the conveyor belt 1 cannot be completely sealed, the smell of tobacco will escape from the gaps in the conveyor belt 1. To avoid this, the air in the preparation chamber 10, the packing chamber 11, and the vacuum chamber 12 is extracted through the air inlets 13, thereby creating a slight negative pressure in each chamber and changing the flow direction in each chamber. Outside air will enter the preparation chamber 10, the packing chamber 11, and the vacuum chamber 12 from the gaps in the conveyor belt 1, while the gas in the preparation chamber 10, the packing chamber 11, and the vacuum chamber 12 cannot escape, further preventing cross-contamination of smells between demonstrations.

[0023] If there is only one air intake 13 on one side of the chamber, air may escape from the bottom of the chamber 9 as the airflow passes around it. Gas further away from the air intake 13 may also escape due to the weaker suction force. To avoid this, the air intake 13 is arranged vertically symmetrically about the center of the first channel 7 and the second channel 8, so that air can be drawn from both sides of the chamber 9, ensuring that the entire chamber is subjected to a relatively uniform suction force and preventing air from flowing out of the chamber.

[0024] The first lifting door 3, the second lifting door 4, the third lifting door 5, and the fourth lifting door 6 have the same structure, only their installation positions differ. Therefore, only the structure of the first lifting door 3 will be described in detail here. The first lifting door 3 includes a door panel 301, a hydraulic cylinder 302, a storage box 303, and a sealing strip. A through hole is opened at the top of the first channel 7. The storage box 303 is vertically installed at the top of the first channel 7 by bolts and communicates with the through hole. The door panel 301 is slidably installed inside the storage box 303. The hydraulic cylinder 302 is installed by bolts on the side of the storage box 303 away from the first channel 7. The moving end of the hydraulic cylinder 302 is connected to the door panel 301 by bolts. A sealing strip is installed on the side wall of the door panel 301 near the inner side wall of the first channel 7. By controlling the extension and retraction of the hydraulic cylinder 302, the door panel 301 is raised and lowered, thereby realizing the opening and closing of the preparation chamber 10, the packing chamber 11, and the vacuum chamber 12.

[0025] If the conveyor belt 1 starts and stops at the same time, all the lifting doors will open simultaneously. The boxes 9 outside the preparation chamber 10 will enter the preparation chamber 10, the original boxes 9 in the preparation chamber 10 will enter the packing chamber 11, the original boxes 9 in the packing chamber 11 will enter the vacuum chamber 12, and the original boxes 9 in the vacuum chamber 12 will leave the vacuum chamber 12. All the boxes 9 move synchronously. However, in this case, when all the lifting doors open at the same time, the isolation effect of the chamber on the odor will be reduced, and the occurrence of cross-contamination of odors cannot be avoided.

[0026] Another approach involves opening the first lifting door 3 to allow the container 9 to enter the preparation chamber 10, then closing the first lifting door 3 and opening the second lifting door 4 to allow the container 9 to enter the packing chamber 11, followed by closing the second lifting door 4. After packing is complete, opening the first lifting door 3 and the third lifting door 5 allows new containers 9 to enter the preparation chamber 10, while the packed containers 9 enter the vacuum chamber 12. Then, closing the first lifting door 3 and the third lifting door 5 completes the vacuuming process. After vacuuming, opening the second lifting door 4 and the fourth lifting door 6 allows new containers 9 to enter the packing chamber 11, while the vacuumed containers 9 leave the vacuum chamber 12. Finally, closing the second lifting door 4 and the fourth lifting door 6 prevents air from escaping from the chamber and causing odor issues. However, this method cannot allow packing and vacuuming to occur simultaneously, resulting in lower efficiency.

[0027] Therefore, this utility model allows the sections of conveyor belt 1 in the preparation chamber 10, packing chamber 11, and vacuum chamber 12 to operate independently. The working principle is as follows: taking advantage of the different time required for packing and vacuuming tobacco, when all three chambers (9) contain boxes (9), after the boxes (9) in the vacuum chamber 12 are vacuumed, the fourth lifting door 6 is opened while the other lifting doors remain closed. The boxes (9) leave the vacuum chamber 12 under the action of conveyor belt 1, and then the second lifting door 4 closes. After the boxes (9) in the packing chamber 11 are packed and sealed, the second and third lifting doors 4 are opened, allowing the boxes (9) in the preparation chamber 10 to enter the packing chamber 11. Simultaneously, the boxes (9) in the packing chamber 11 enter the vacuum chamber 12. Then, the second and third lifting doors 4 and 5 are closed, and the boxes (9) are packed and vacuumed separately. During the packing and vacuuming process, the first lifting door 3 is opened to allow empty boxes (9) to enter the preparation chamber 10, and then the first lifting door 3 is closed. By controlling the conveyor belt 1 in this way, the packing and vacuuming can be carried out simultaneously, ensuring that the tobacco packing machine 2 is at a higher working efficiency and improving the production efficiency of tobacco packaging while ensuring that the flavors do not mix.
