Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, and in particular to a cigarette recycling device. Background Technology

[0002] In the tobacco processing production line, the cigarette conveying device of the packaging machine is equipped with a cigarette quality detection device. This device detects whether there are any defective cigarettes, such as empty heads or missing tips, in each group of 20 cigarettes. When the quality detection device detects one or more defective cigarettes, it sends a signal to the rejection device. The rejection device's push rod extends, rejecting the entire group of cigarettes containing the defective cigarettes. The rejected group of cigarettes slides onto the conveyor belt that carries the rejected cigarettes. At the end of the conveyor belt is a receiving bin, where the last rejected group of cigarettes falls. Workers then sift through the cigarettes in the receiving bin, inspecting their quality one by one. Defective cigarettes are retained, while qualified cigarettes are arranged in the slots of cigarette cards and returned to the production process.

[0003] The conveyor belt used to transport rejected cigarettes is too far vertically from the bottom of the receiving bin. As the rejected cigarettes fall freely, they generate impact velocity. When these falling cigarettes collide with the bottom of the receiving bin or with already stacked cigarettes, they are prone to damage such as tip sinking, wrinkling, and tobacco shedding. This causes some initially acceptable cigarettes to become unacceptable after falling into the receiving bin. Furthermore, the cigarettes inside the receiving bin are stacked haphazardly, with random orientations and angles, making it difficult for workers to pick them up and inspect. This results in low cigarette inspection efficiency and negatively impacts tobacco processing efficiency.

[0004] Therefore, there is an urgent need for a cigarette recycling device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cigarette recycling device. When rejected cigarettes fall, they may hit the bottom of the cigarette receiving canister or the already stacked cigarettes, which can easily cause damage such as cigarette end sinking, cigarette wrinkling, and tobacco shedding. This causes some originally qualified cigarettes to become unqualified cigarettes after falling into the cigarette receiving canister. At the same time, the cigarettes in the cigarette receiving canister are stacked in a disorderly state, which makes it inconvenient for staff to pick them up and inspect them, resulting in low cigarette inspection efficiency and affecting the efficiency of tobacco processing.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A cigarette recycling device is used to recover cigarettes rejected from a production line. The rejected cigarettes are removed by the rejection device and slide onto a conveyor belt. The cigarette recycling device includes:

[0008] The device includes a support and a first guide plate. The support is located below the end of the conveyor belt, and the first guide plate is inclined and placed on the support, contacting the end of the conveyor belt. The first guide plate is provided with a plurality of spaced first guide blocks and a plurality of spaced second guide blocks along the vertical direction. A diversion channel is formed between adjacent second guide blocks. When the cigarette falls from the conveyor belt to the guide plate, the first guide blocks can adjust the falling direction of the cigarette, so that multiple cigarettes enter multiple diversion channels.

[0009] Multiple correction tubes and multiple conveying slides are provided. The correction tubes are correspondingly arranged with the multiple diversion channels. One end of the correction tube is placed in the diversion channel. The correction tube can fix the falling direction of the cigarette. The multiple conveying slides are correspondingly arranged with the multiple correction tubes. The conveying slide includes an arc-shaped tube and a second guide plate. One end of the arc-shaped tube is connected to the end of the correction tube away from the diversion channel, and the other end is horizontal and has a semi-circular opening. The second guide plate is connected to the lower end of the semi-circular opening.

[0010] The cigarette receiving box has a width L1 that is 1.1 to 1.2 times the length of the cigarette. The cigarette receiving box includes a receiving section and a receiving section. The receiving section is located below the conveyor slide and is inclined. The receiving section is connected to the receiving section through an arc surface. The receiving section is used to receive the cigarette.

[0011] As a preferred technical solution for the cigarette recycling device, the first guide block is a rhomboid prism, and the adjacent faces of the rhomboid prism are connected by rounded corners.

[0012] As a preferred technical solution for the cigarette recycling device, the second guide block includes a pointed corner and a cylindrical part. The two included sides of the pointed corner are connected by an arc surface, and the cigarette enters the correction tube along the cylindrical part.

[0013] As a preferred technical solution for the cigarette recycling device, multiple first guide blocks are arranged at intervals, and the distance between adjacent first guide blocks is greater than the length of the cigarette.

[0014] Multiple second guide blocks are arranged at intervals, and the spacing between adjacent second guide blocks is 1 to 2 times the diameter of the cigarette.

[0015] As a preferred technical solution for the cigarette recycling device, the multiple first guide blocks are arranged in a staggered manner at different heights.

[0016] The multiple second guide blocks are arranged at different heights.

[0017] As a preferred technical solution for the cigarette recycling device, the first guide plate is provided with a first baffle on both sides, and / or the second guide plate is provided with a second baffle on both sides.

[0018] As a preferred technical solution for the cigarette recycling device, both the first baffle and the second baffle are made of silicone.

[0019] As a preferred technical solution for the cigarette recycling device, the first guide plate is set at a 15° angle to the vertical direction.

[0020] As a preferred technical solution for the cigarette recycling device, both the first guide block and the second guide block are made of silicone.

[0021] As a preferred technical solution for the cigarette recycling device, the correction tube is funnel-shaped, including a large opening and a small opening. The large opening is located at the end of the diversion channel, and the diameter of the small opening is 1.1 to 1.2 times the diameter of the cigarette. The conveying chute is connected to the small opening.

[0022] The beneficial effects of this utility model are:

[0023] The cigarette recycling device provided by this utility model is installed at the end of a conveyor belt used for conveying rejected cigarettes. Multiple cigarettes falling from the conveyor belt will fall onto a first guide plate. After contacting the first guide block, the cigarettes will adjust to a position with the cigarette butt or mouthpiece facing down under their own gravity. They will then enter between multiple second guide blocks, i.e., into a diversion channel, and then into a correction tube. The correction tube corrects the direction of the cigarettes entering the tube, fixing their orientation. They will then enter a conveyor chute, becoming horizontal as they slide out of the chute, and fall horizontally into the receiving section of the cigarette receiving box. After passing through the receiving section and a curved transition, they roll into the receiving section of the cigarette receiving box and are stacked in an orderly manner. Throughout the entire process, the cigarettes will not experience excessive impact. Therefore, there is no risk of cigarette ends sinking, cigarette wrinkling, or tobacco falling out when cigarettes enter the cigarette receiving box, avoiding the situation where a qualified cigarette becomes an unqualified cigarette after entering the cigarette receiving box. Meanwhile, the cigarettes entering the cigarette box are all stacked horizontally, making it easier for staff to pick up and inspect the cigarettes one by one, eliminating the need for staff to arrange the direction of the cigarettes, and greatly improving the efficiency of cigarette recycling.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 5 As shown, this utility model provides a cigarette recycling device for recycling cigarettes 101 rejected from the production line. The rejection device removes groups of defective cigarettes 101, which slide onto a conveyor belt 100. The conveyor belt 100 then transports the rejected cigarettes 101 to the cigarette recycling device. The cigarette recycling device includes a support 1, a first guide plate 2, multiple correction pipes 3, multiple conveying tracks 4, and a cigarette receiving box 5. The support 1 is located below the end of the conveyor belt 100. The first guide plate 2 is inclinedly mounted on the support 1 and contacts the end of the conveyor belt 100. The first guide plate 2 has multiple first guide blocks 21 and multiple second guide blocks 22 spaced apart along the vertical direction. A diversion channel 23 is formed between adjacent second guide blocks 22. After the cigarette 101 falls from the conveyor belt 100 onto the first guide plate 2, the first guide block 21 can adjust the direction of the cigarette 101, so that multiple cigarettes 101 enter multiple diversion channels 23. That is, the cigarette 101 falling onto the first guide plate 2 will first contact the first guide block 21. After contacting the first guide block 21, the cigarette 101 will change direction under the action of its own gravity, and then enter the diversion channel 23. Specifically, the originally disordered cigarettes 101 will be adjusted to have the cigarette butt or mouthpiece facing down after contacting the first guide block 21, and enter multiple diversion channels 23. Setting multiple first guide blocks 21 and multiple second guide blocks 22 can improve the speed of orientation adjustment and recovery of multiple cigarettes 101, and avoid the accumulation of multiple cigarettes 101 at the first guide plate 2.

[0037] Multiple correction tubes 3 are correspondingly arranged with multiple diversion channels 23. One end of the correction tube 3 is placed in the diversion channel 23. The correction tube 3 can fix the falling direction of the cigarette 101. The falling direction of the cigarette 101 refers to the overall falling direction of the cigarette 101. When the cigarette 101 falls, it can be with the mouthpiece facing down or the cigarette butt facing down, without restriction. Multiple conveying slides 4 are correspondingly arranged with multiple correction tubes 3. The conveying slide 4 includes an arc-shaped tube 41 and a second guide plate 42. One end of the arc-shaped tube 41 is connected to the end of the correction tube 3 away from the diversion channel 23, and the other end is horizontal and has a semi-circular opening 411. The second guide plate 42 is connected to the lower end of the semi-circular opening 411. The cigarette 101 will eventually be conveyed horizontally to the semi-circular opening 411 and roll down along the second guide plate 42. The width of the cigarette receiving box 5 is 1.1 to 1.2 times the length of the cigarette 101. The cigarette receiving box 5 includes a receiving section 51 and a receiving section 52. The receiving section 51 is located below the conveyor slide 4 and is inclined. The receiving section 51 is connected to the receiving section 52 through an arc surface. The receiving section 52 is used to receive the cigarette 101. The cigarette 101 that rolls down from the second guide plate 42 falls to the receiving section 51 in a horizontal state. The inclined setting of the receiving section 51 allows the cigarette 101 to roll to the receiving section 52. Due to the limitation of the width of the cigarette receiving box 5, the cigarette 101 is prevented from deviating during the rolling process. The connection between the receiving section 51 and the receiving section 52 through the arc surface can ensure that the cigarette 101 rolls smoothly and steadily to the receiving section 52, so that the cigarette 101 is stacked in an orderly manner in the receiving section 52.

[0038] The cigarette recycling device provided in this embodiment is installed at the end of the conveyor belt 100 used to transport and discard cigarettes 101. Multiple cigarettes 101 falling from the conveyor belt 100 will fall onto the first guide plate 2. After the cigarettes 101 come into contact with the first guide block 21, they will adjust to a position with the cigarette butt or mouthpiece facing down under their own gravity. Then they will enter between multiple second guide blocks 22, that is, enter the diversion channel 23, and then enter the correction tube 3. The correction tube 3 corrects the direction of the cigarettes 101 entering it, fixes the direction of the cigarettes 101, and then enters the conveyor slide 4. After sliding out of the conveyor slide 4, it becomes horizontal and slides out of the conveyor slide 4 in a horizontal state, falling onto the receiving section 51 of the cigarette receiving box 5. After passing through the receiving section 51 and the arc transition, it rolls to the receiving section 52 of the cigarette receiving box 5 and is stacked in an orderly manner. Throughout the process, cigarettes 101 will not experience excessive impact. Therefore, there is no risk of filter sagging, cigarette wrinkling, or tobacco falling out when cigarettes 101 enter the receiving box 5. This avoids the situation where a qualified cigarette 101 becomes an unqualified cigarette 101 after entering the receiving box 5. At the same time, the cigarettes 101 entering the receiving box 5 are all stacked horizontally, making it easier for staff to handle and inspect each cigarette 101 individually. This eliminates the need for staff to orient the cigarettes 101 and significantly improves the recycling efficiency of cigarettes 101.

[0039] In this embodiment, the first guide block 21 is a rhomboid prism, and adjacent faces of the rhomboid prism are connected by rounded corners. Thus, when the cigarette 101 falls from the conveyor belt 100 onto the first guide plate 2, it will contact the rounded corners of the rhomboid prism. Under the influence of the cigarette 101's gravity, the falling direction of the cigarette 101 is adjusted, ensuring the cigarette tip or mouthpiece faces downwards, and it is guided along the side of the rhomboid prism into the diversion channel 23. By connecting adjacent sides of the rhomboid prism with rounded corners, damage to the cigarette 101 can be avoided when it contacts the rhomboid prism.

[0040] Furthermore, the second guide block 22 includes a pointed corner 221 and a cylindrical section 222. The two included edges of the pointed corner 221 are connected by an arc surface. The cigarette 101 enters the correction tube 3 along the cylindrical section 222. After the cigarette 101 changes direction upon contact with the first guide block 21, it contacts the included edge of the pointed corner 221. The included edge acts as a guide, causing the cigarette 101 to enter between the two cylindrical sections 222 of two adjacent second guide blocks 22, that is, into the diversion channel 23, and finally into the correction tube 3. The two included edges are connected by an arc surface to prevent damage to the cigarette 101 when it contacts the pointed corner 221. Specifically, when the cigarette 101 moves along the included edge and is partially exposed, the bend between the pointed corner 221 and the cylindrical section 222 forms a fulcrum. Under the action of gravity, the cigarette 101 turns and enters the diversion channel 23.

[0041] The multiple first guide blocks 21 are spaced apart, ensuring consistent spacing between them and facilitating their arrangement. The distance between adjacent first guide blocks 21 is greater than the length of the cigarette 101. This ensures sufficient space for the cigarette 101 to change direction under gravity after contact with the first guide blocks 21, preventing it from becoming blocked between them. This allows the cigarette 101 to smoothly enter the correction tube 3 and finally the cigarette receiving box 5. Furthermore, the multiple second guide blocks 22 are spaced apart, with the spacing between adjacent second guide blocks 22 being 1 to 2 times the diameter of the cigarette 101. This ensures that the cigarette 101 moving along the included side can smoothly enter the adjacent column portion 222 under the action of gravity, that is, smoothly enter the diversion channel 23, reducing the risk of the cigarette 101 getting stuck between the second guide blocks 22. This allows the cigarette 101 falling from the conveyor belt 100 to smoothly, evenly and quickly enter the cigarette receiving box 5.

[0042] The multiple first guide blocks 21 are arranged at varying heights. This further increases the space for the cigarette 101 to rotate under gravity after contacting the first guide blocks 21, further reducing the risk of multiple cigarettes 101 getting stuck between the first guide blocks 21, allowing the cigarette 101 to smoothly enter the diversion channel 23 and improving the cigarette 101 recovery efficiency. Furthermore, the multiple second guide blocks 22 are arranged at varying heights, which further increases the space for the cigarette 101 to move along the second guide blocks 22 and partially exposed, turning by the fulcrum formed by the sharp corner 221 and the bend of the column 222, further reducing the risk of the cigarette 101 getting stuck when passing through the second guide blocks 22, and improving the smoothness of the cigarette 101 passing through the first guide plate 2.

[0043] In this embodiment, first baffles 24 are provided on both sides of the first guide plate 2. The first baffles 24 prevent the cigarette 101 from falling off as it rolls along the first guide plate 2, further reducing the risk that a qualified cigarette 101 becomes an unqualified cigarette 101 during the recycling process. And / or, second baffles 421 are provided on both sides of the second guide plate 42. The second baffles 421 prevent the cigarette 101 from falling off the second guide plate 42, allowing the cigarette 101 to smoothly enter the receiving section 51 of the cigarette receiving box 5, and finally be stacked orderly in the receiving section 52. Furthermore, the first baffles 24 and the second baffles 421 are both made of silicone. Thus, when the cigarette 101 collides with the first baffles 24 and the second baffles 421, the cigarette 101 will not deform, ensuring the quality of the cigarette 101 and further reducing the risk that a qualified cigarette 101 becomes an unqualified cigarette 101 during the process of being conveyed to the cigarette receiving box 5, thereby improving the rationality of the cigarette recycling device design.

[0044] In this embodiment, the first guide plate 2 is set at a 15-degree angle to the vertical direction. This ensures that after the cigarette 101 passes through the first guide block 21 and enters the diversion channel 23, the direction of the cigarette 101 is close to the vertical direction, which makes the sliding of the cigarette 101 in the conveying slide 4 smoother, reduces the risk of the cigarette 101 getting clogged, and makes the design of the cigarette recycling device more reasonable.

[0045] In this embodiment, the first guide block 21 and the second guide block 22 are both made of silicone. When the cigarette 101 collides with the first guide block 21 and the second guide block 22, the first guide block 21 and the second guide block 22 can provide a certain buffer for the cigarette 101, reduce the risk of deformation of the cigarette 101 after the impact, and thus reduce the risk of qualified cigarette 101 becoming unqualified cigarette 101 during the process of being transferred to the cigarette receiving box 5, thereby reducing the waste of cigarette 101.

[0046] In this embodiment, the correction tube 3 is trumpet-shaped, including a large opening and a small opening. The large opening is located at the end of the diversion channel 23, and the diameter of the small opening is 1.1 to 1.2 times the diameter of the cigarette 101. The conveying chute 4 is connected to the small opening. The cigarette 101 falls from the diversion channel 23 and enters the large opening of the correction tube 3. As the diameter of the correction tube 3 gradually decreases, the angle of the falling direction of the cigarette 101 gradually decreases. When the cigarette 101 enters the conveying chute 4 through the small opening, the falling direction of the cigarette 101 is fixed. The size of the small opening ensures that the cigarette 101 smoothly enters the conveying chute 4 and then smoothly enters the cigarette receiving box 5.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
