Description

Technical Field

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

[0002] In the tobacco industry, as the proportion of tobacco products in cigarette formulations gradually increases, the use of boxed materials inevitably involves the boxing process. Based on research and analysis of the production process and current status of tobacco processing lines, boxing devices with different technical routes and structures have emerged to replace the various drawbacks of entirely manual boxing in some enterprises. Existing boxing devices have the disadvantages of large footprint and low boxing efficiency, and there is still room for further improvement. Therefore, existing patent document CN201922495118.7 proposes a new type of tobacco boxing device suitable for high-volume finished tobacco boxing and also meeting the continuous production requirements of tobacco processing lines. It performs tobacco boxing through dual-station operation, thereby meeting the boxing requirements of high-volume continuous production of tobacco processing lines and improving the overall boxing efficiency of the production line.

[0003] However, the following problems were found in actual use: First, the dust generated during the packing of tobacco shreds is relatively large, which not only affects the surrounding environment but also the health of personnel and is not conducive to safe production; Second, during the packing process, it is impossible to ensure that the tobacco shreds are spread evenly in the tobacco box, and a press head is required to compact them during packing; Third, when automatically packing finished tobacco shreds, due to the large inflow and uneven material distribution, the traditional metering table suspension method will produce a large metering error.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A tobacco packing system includes a tobacco packing line consisting of several conveying mechanisms, packing station A and packing station B arranged on the tobacco packing line; a closed transverse tobacco conveyor is provided between packing station A and packing station B, and the middle of the closed transverse tobacco conveyor is connected to a closed longitudinal tobacco conveyor.

[0007] Both packing station A and packing station B are equipped with an outer frame and an inner frame. The outer frame is placed on the ground, and the inner frame is placed inside the outer frame by a weighing mechanism. The inner frame is equipped with, from top to bottom, a feeding hopper that connects to the horizontal tobacco conveyor, a box lifting mechanism that can move vertically at the outlet of the feeding hopper and connect to the tobacco box, and a tobacco box located inside the inner frame and on the tobacco box conveyor line.

[0008] Furthermore, among the several conveyors of the cigarette box conveying line, there are two conveyors installed at the bottom of the equipment's internal frame, and two conveyors located between packing station A and packing station B.

[0009] Furthermore, both the enclosed transverse tobacco conveyor and the enclosed longitudinal tobacco conveyor include a conveyor and a closed cover installed on the upper part of the conveyor; the enclosed longitudinal tobacco conveyor extends into the closed cover of the transverse tobacco conveyor, and a first feeding mechanism is also provided at the connection between the enclosed transverse tobacco conveyor and the enclosed longitudinal tobacco conveyor.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] To address the problems existing in high-volume finished tobacco shred packaging equipment, this embodiment provides a tobacco shred packaging system. For example... Figure 1 As shown, the tobacco packing system includes a tobacco box conveyor line 1 composed of several conveying mechanisms, and packing stations A29 and B30 arranged on the tobacco box conveyor line 1; a closed transverse tobacco conveyor 2 is provided between packing station A29 and packing station B30, and the middle of the closed transverse tobacco conveyor 2 is connected to a closed longitudinal tobacco conveyor 3.

[0029] Both packing stations A29 and B30 are equipped with an outer frame 4 and an inner frame 5. The outer frame 4 is placed on the ground, and the inner frame 5 is placed inside the outer frame 4 via a weighing mechanism 6. The inner frame 5 is equipped with, from top to bottom, a feed hopper 7 that connects to the transverse tobacco conveyor, a box-lifting mechanism 8 located at the outlet of the feed hopper 7 that can move vertically and connect to the tobacco box 28, and the tobacco box 28 located within the inner frame 5 and on the tobacco box conveyor line 1.

[0030] The following is a detailed structural and functional description of each component of the tobacco packing system:

[0031] Smoke box conveyor line 1: such as Figure 1 As shown, the function of the cigarette box conveyor line 1 is to transport empty cigarette boxes 28 and full cigarette boxes 28 after tobacco shreds have been packed, while also allowing the empty and full cigarette boxes 28 to stop at various workstations to coordinate with the tobacco shred packing work. The cigarette box conveyor line 1 includes several conveyors, including two conveyors installed at the bottom of the internal frame 5 of the equipment, and two conveyors located between packing station A29 and packing station B30.

[0032] Enclosed longitudinal tobacco conveyor 3 and enclosed transverse tobacco conveyor 2: such as Figure 2 As shown, the enclosed longitudinal tobacco conveyor 3 is used for the longitudinal transport of tobacco shreds. It includes a conveyor and a first enclosed cover 9 installed on the upper part of the conveyor. The first enclosed cover 9 can enclose the conveyor to prevent dust from being generated and spilled during the transport of tobacco shreds. Figure 1 As shown, the enclosed transverse tobacco conveyor 2 is used for transverse conveying of tobacco shreds. By rotating clockwise or counterclockwise, the tobacco shreds can be conveyed to packing station A29 or packing station B30, achieving continuous packing. The enclosed transverse tobacco conveyor 2 includes a conveyor and a second enclosed cover 10 installed on the upper part of the conveyor. The second enclosed cover 10 can enclose the conveyor to prevent dust generation and spillage during tobacco shred conveying. The enclosed longitudinal tobacco conveyor 3 extends into the second enclosed cover 10 of the transverse tobacco conveyor, completely sealing the tobacco shred conveying process. Figure 2 As shown, in order to prevent the tobacco from accumulating when it is transferred from the closed longitudinal tobacco conveyor 3 to the closed transverse tobacco conveyor 2, a first feeding mechanism 11 is provided at the junction of the closed transverse tobacco conveyor 2 and the closed longitudinal tobacco conveyor 3 in this embodiment.

[0033] Feed hopper 7: such as Figure 1 As shown, the feed hopper 7 is a box structure with openings on one side and the bottom. The feed hopper 7 is connected to both ends of the enclosed transverse tobacco conveyor via its side inlet, and its bottom outlet is connected to the tobacco box 28 via a lifting mechanism 8. The feed hopper 7 receives tobacco from the enclosed transverse tobacco conveyor 2 and transfers it to the tobacco box 28. To prevent the tobacco from accumulating after falling through the feed hopper 7, such as... Figure 1 As shown, in this embodiment, a second feeding mechanism 12 is installed in the upper part of the outer frame 4 of the equipment, and the second feeding mechanism 12 extends into the feeding hopper 7.

[0034] Box Lifting Mechanism 8: such as Figure 1 As shown, the casing lifting mechanism 8 is used to connect the discharge port of the feed hopper 7 with the top opening of the tobacco box 28. Figure 3 and Figure 4 As shown, the lifting mechanism 8 includes an upper fixed rectangular tube 22 fixedly installed at the outlet of the feed hopper 7, a drive 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 via a fixed seat, and a sliding interface rectangular tube 24 fitted onto the upper fixed rectangular tube 22 at the output end of the drive power source 23. Furthermore, considering the sealing issue, such as... Figure 4 As shown, in this embodiment, an upper sealing protection 25 that cooperates with the upper fixed rectangular tube 22 is provided above the sliding interface rectangular tube 24, and a slope interface that opens to the top of the cigarette box 28 is provided below the sliding interface rectangular tube 24, and a lower sealing protection 26 that cooperates with the cigarette box 28 is provided at the slope interface.

[0035] Weighing mechanism 6: such as 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. These sensors are used to weigh the tobacco shreds in the boxes, so that the weight of the tobacco shreds in each box 28 is uniform, thus ensuring the standardization of the tobacco shreds in each box 28.

[0036] The working principle of the tobacco packing system described above is as follows:

[0037] First, such as Figure 1 As shown, the conveyor of the cigarette box conveyor line 1 transports the empty cigarette box 28 to the packing station A29 and the packing station B30. Then, the box lifting mechanism 8 is activated, and the sliding interface rectangular tube 24 driven by the power source 23 moves downward to match the top opening of the cigarette box 28. At this time, the enclosed longitudinal tobacco conveyor 3, the enclosed transverse tobacco conveyor 2, the feed hopper 7, the box lifting mechanism 8, and the cigarette box 28 are in a sealed and connected state to prevent dust and spillage during the tobacco packing process. The enclosed longitudinal tobacco conveyor 3 and the enclosed transverse tobacco conveyor 2 are started. The tobacco shreds are evenly distributed from the enclosed longitudinal tobacco conveyor 3 to the enclosed transverse tobacco conveyor 2 via the first feeding mechanism 11, and then conveyed by the enclosed transverse tobacco conveyor 2 to the feeding hopper 7 on either side. After entering the feeding hopper 7, the tobacco shreds fall into the tobacco box 28 via the box lifting mechanism 8. At the same time, the second feeding mechanism 12 in the feeding hopper 7 ensures that the tobacco shreds are evenly spread and prevents them from piling up in any position in the tobacco box 28. During the tobacco packing process, the weighing sensors at the four corners of the bottom of the inner frame weigh the conveyors, tobacco box 28 and tobacco shreds in the box, the box lifting mechanism 8, and the feeding hopper 7 in real time, avoiding the influence of the weighing of various moving parts and basically maintaining static weighing, so as to ensure accurate weighing.

[0038] After the tobacco shreds are packed at packing station A29, the box lifting mechanism 8 drives the sliding interface rectangular tube 24, powered by the power source 23, to move upwards and separate from the top opening of the tobacco box 28. At the same time, the enclosed horizontal tobacco shred conveyor 2 runs in reverse to pack the tobacco shreds at packing station B30. Then, the full tobacco box 28 leaves packing station A29 and waits for the tobacco shreds at packing station B30 to be packed before being transported to the next process. Meanwhile, a new empty tobacco box 28 is transported to packing station A29 to wait for tobacco shreds to be packed, thus achieving continuous tobacco shred packing and completing high-efficiency, fully automated tobacco shred packing.

[0039] Furthermore, as a preferred technical solution in this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the first feeding mechanism 11 and the second feeding mechanism 12 in this embodiment have similar structures, both including a feeding power source, a drive shaft, a drive rod, and a feeding plate. The drive shaft 14 of the first feeding mechanism is rotatably mounted on the closed cover of the enclosed transverse tobacco conveyor 2 via a bearing seat; the drive shaft 18 of the second feeding mechanism is rotatably mounted on the outer frame 4 of the equipment via a bearing seat, and the drive shaft 18 of the second feeding mechanism passes through the feed hopper 7. The feeding power source 13 of the first feeding mechanism is mounted on the outer end of the enclosed longitudinal tobacco conveyor 3 via a mounting seat, and is connected to the drive shaft via the drive rod 15 of the first feeding mechanism; the feeding power source 17 of the second feeding mechanism is mounted on the outer frame 4 of the equipment via a mounting seat, and is connected to the drive shaft via the drive rod 19 of the second feeding mechanism. The feeding plate 16 of the first feeding mechanism is located inside the closed cover of the enclosed transverse tobacco conveyor 2, and one end of it is installed on the drive shaft 14 of the first feeding mechanism; the feeding plate 20 of the second feeding mechanism is located inside the feed hopper 7, and one end of it is installed on the drive shaft 18 of the second feeding mechanism through a connector.

[0040] The first feeding mechanism 11 and the second feeding mechanism 12 both drive the drive shaft to rotate via the drive rod. While the drive shaft rotates, it drives the feeding plate to swing, thereby achieving uniform feeding of materials to the enclosed transverse tobacco conveyor 2 and uniform spreading of tobacco into the tobacco box 28.

[0041] Furthermore, as a preferred technical solution in this embodiment, such as Figure 1 As shown, in this embodiment, the closed cover of the enclosed transverse tobacco conveyor 2 is provided with pipe interfaces 21 at both ends for connection to the workshop dust removal system pipeline; the workshop dust removal system pipeline can be connected through the pipe interface 21 to suck up the dust and overflow during the tobacco packing process and prevent it from falling into the tobacco box 28.

[0042] Furthermore, as a preferred technical solution in this embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, a cover-clamping mechanism 27 is installed inside the outer frame 4 of the device between the lifting mechanism 8 and the top opening of the cigarette box 28. The cover-clamping 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.

[0043] It should be noted that, in this embodiment, the driving power source 23 and the material feeding power source mentioned can be a cylinder or an electric cylinder, or a motor combined with a gear and rack structure to achieve the corresponding action.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
