Description
Technical Field
[0001] The utility model belongs to the field of tobacco equipment, and in particular relates to a tobacco leaf conveying and cutting device. Background Art
[0002] In the domestic tobacco industry, it is necessary to cut the raw tobacco leaves after preliminary drying. At present, the raw tobacco leaf cutting machine in the tobacco industry generally uses belt conveyor to feed the materials in the cutting process after the materials are fed by the front leaf laying belt conveyor. That is, the cutting machine mainly uses belt conveyor and cutting knife to transport and cut.
[0003] However, tobacco leaves after preliminary drying contain a lot of tobacco oil, which is easy to produce during cutting and subsequent transportation. The tobacco oil is easy to adhere to the belt of the cutter and the tobacco leaves that are subsequently fed, resulting in poor transportation or impure tobacco leaves. In addition, the belt conveyor is easy to deviate during the transportation process, causing the belt to be cut by the cutter and fall into the tobacco leaves, making the tobacco leaves impure, which further causes equipment shutdown and affects production. It is difficult to ensure the purity of the tobacco leaves and stable transmission efficiency and stability.
[0004] In view of this, the present utility model is proposed. Utility Model Content
[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art, and the purpose is to provide a tobacco conveying and cutting device. The module mesh belt is set as the conveyor belt of the tobacco conveying and cutting device, which can improve the stability of transportation; in addition, the module mesh belt is an anti-sticking oil module mesh belt. The tobacco oil generated when the tobacco leaves are cut can drip from the module mesh belt and will not stick to the module mesh belt and the subsequently conveyed tobacco leaves, thereby ensuring the purity of the conveyed tobacco leaves and will not affect the transportation of the tobacco leaves.
[0006] In order to solve the above technical problems, the basic idea of the technical solution adopted by the utility model is to provide a tobacco leaf conveying and cutting device, including:
[0007] The conveyor comprises a rotating roller and a rotatable modular mesh belt sleeved outside the rotating roller, wherein the modular mesh belt is an anti-sticking oil modular mesh belt for conveying raw tobacco leaves;
[0008] The cutter is arranged on the conveyor and is used for cutting the tobacco leaves conveyed by the module mesh belt.
[0009] Furthermore, the cutting machine comprises a cutter, which is located outside the two sides of the conveying direction of the module mesh belt, and at least the blade part of the cutter is an anti-sticking oil structure.
[0010] Further, the cutting machine includes a cutter frame, which is arranged on the frame of the conveyor; the cutter includes an upper cutter and a lower cutter, which are movably arranged on the cutter frame; the upper cutter and the lower cutter are respectively located above and below the module mesh belt, and move to cooperate to cut the tobacco leaves conveyed by the module mesh belt;
[0011] The upper cutting knife and the lower cutting knife are of an anti-sticking oil structure.
[0012] Furthermore, the anti-sticking oil structure is made of an anti-sticking oil material or is coated with an anti-sticking oil coating.
[0013] Furthermore, the rotating roller comprises an active roller and a driven roller, and the active roller and the driven roller are both provided with a rotating shaft and a sprocket, and the sprocket is sleeved and fixed on the outer periphery of the rotating shaft;
[0014] The module mesh belt is rotatably wound on the sprockets of the active roller and the driven roller, the teeth on the outer periphery of the sprocket are meshed and transmission-connected with the grooves on the inner periphery of the module mesh belt in sequence, and the sprocket is an anti-oil sprocket.
[0015] Furthermore, the module mesh belt is made of polypropylene, and the sprocket is made of polyamide.
[0016] Furthermore, the interior of the sprocket has a through shaft hole, the shaft hole and the rotating shaft are non-circular, and the sprocket is sleeved on the outer circumference of the rotating shaft and fixedly connected by a chuck.
[0017] Furthermore, the interior of the sprocket has a through shaft hole, the shaft hole and the outer peripheral wall of the rotating shaft are square shapes that match each other, and the rotating shaft is fixedly installed in the shaft hole.
[0018] Furthermore, it also includes a chain rail, which is at least partially arranged on the upper surface of the module mesh belt and can be synchronously operated with the module mesh belt, and is used to fix the tobacco leaves on the module mesh belt, and the cutting machine performs cutting;
[0019] The chain rail is made of anti-sticking oil material.
[0020] Furthermore, an oil receiving structure is provided at the lower part of the conveyor, which is located below the module mesh belt and the cutter and is used to receive the smoke oil dropped from above.
[0021] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art.
[0022] (1) In the tobacco leaf conveying and cutting device of the utility model, the roller is connected to the module mesh belt by transmission, which can make the module mesh belt rotate stably, avoid the module mesh belt being damaged by the cutter when cutting tobacco leaves, and maintain the cleanliness of tobacco leaves. In addition, the design of the anti-sticking oil module mesh belt can effectively prevent the oil of tobacco leaves after cutting from adhering to the module mesh belt, keep the module mesh belt clean, thereby improving the conveying efficiency and reducing the device failure and maintenance cost caused by oil stains.
[0023] (2) Since the module mesh belt, sprocket, upper cutter and lower cutter are all designed with anti-stick oil, oil stains will not adhere to these parts during the entire conveying and cutting process, ensuring the cleanliness and efficient operation of the device. This not only improves processing efficiency, but also ensures the stability and consistency of product quality.
[0024] (3) A stable connection method, such as a flat key connection or a spline connection, is used between the sprocket and the shaft to ensure the synchronous rotation between the sprocket and the shaft, and effectively prevent the sprocket from loosening or falling off during high-speed operation, thereby avoiding the deviation of the module mesh belt and causing the tobacco leaves to be cut badly. The contact area between the module mesh belt and the roller is larger during the movement, thereby improving the transmission efficiency. This stable connection relationship not only further improves the stability and reliability of the conveying process, improves the stability of the device, but also further extends the service life of the device.

[0034] like Figure 1 to Figure 2 As shown, the utility model provides a tobacco leaf conveying and cutting device, which is used for conveying and cutting tobacco leaves after preliminary drying.
[0035] The tobacco leaf conveying and cutting device comprises a conveyor 1 and a cutter.
[0036] The conveyor 1 comprises a roller 11 and a module mesh belt 12 rotatably sleeved on the outside of the roller 11. The module mesh belt 12 is an anti-sticking oil module mesh belt 12, which is used to convey raw tobacco leaves that have been preliminarily dried. The cutter is arranged on the conveyor 1, and is used to cut the tobacco leaves conveyed by the module mesh belt 12.
[0037] In the tobacco leaf conveying and cutting device of the utility model, the roller 11 is connected to the module mesh belt 12 in a transmission manner, so that the module mesh belt 12 can rotate stably, and the cutter can avoid damaging the module mesh belt 12 when cutting tobacco leaves, thereby maintaining the cleanliness of tobacco leaves. In addition, the design of the anti-sticking oil module mesh belt 12 can effectively prevent the oil of the tobacco leaves after cutting from adhering to the module mesh belt 12, and keep the module mesh belt 12 clean, thereby improving the conveying efficiency and reducing the device failure and maintenance cost caused by the adhesion of oil stains.
[0038] Furthermore, the cutting machine includes a cutter, and the cutter is located outside the two sides of the conveying direction of the module mesh belt 12. At least the blade part of the cutter is an anti-sticking oil structure, and the entire cutter can also be an anti-sticking oil structure.
[0039] The cutters of the cutting machine of the utility model are located on both sides of the conveying direction of the module mesh belt 12, and can cut the tobacco leaves conveyed on the module mesh belt 12, and avoid cutting the module mesh belt 12. At least the blade of the cutter is an anti-sticking oil structure, and the blade of the anti-sticking oil structure can effectively prevent oil stains from adhering when cutting tobacco leaves, ensuring smooth and accurate cutting, and extending the service life of the cutter.
[0040] In the utility model, the upper cutting knife 22 and the lower cutting knife 23 can be used to cut tobacco leaves in a coordinated manner.
[0041] A preferred solution is that the cutting machine includes a cutter frame 21, which is arranged on the frame 13 of the conveyor 1. The cutter includes an upper cutter 22 and a lower cutter 23, which are movably arranged on the cutter frame 21. The upper cutter 22 and the lower cutter 23 are respectively located above and below the module mesh belt 12. The upper cutter 22 and the lower cutter 23 move and cooperate to cut the tobacco leaves conveyed by the module mesh belt 12 and partially located on both sides of the conveying direction of the module mesh belt 12. This design makes tobacco leaf cutting more accurate and efficient.
[0042] The upper cutter 22 and the lower cutter 23 are of an anti-sticking oil structure. The anti-sticking oil design of the upper cutter 22 and the lower cutter 23 can ensure that the oil of the tobacco leaves will not adhere to the cutter during the cutting process, thereby improving the cutting efficiency and quality and reducing the frequency of cleaning and maintenance.
[0043] The upper cutter 22 and the lower cutter 23 can be rotatably arranged on the cutter frame 21, similar to scissors for cutting tobacco leaves. The upper cutter 22 and the lower cutter 23 can be arranged on the cutter frame 21 to move up and down, and when they move close to each other, they can rotate and cut tobacco leaves. Preferably, the upper cutter 22 can be arranged to move up and down.
[0044] Furthermore, the anti-sticking oil structure is made of an anti-sticking oil material, such as an anti-sticking oil metal, or both sides of the cutter are coated with an anti-sticking oil coating, such as a polyimide coating, polytetrafluoroethylene (PTFE), etc.
[0045] like Figure 2 As shown, the rotating roller 11 includes a driving roller and a driven roller, and the driving roller and the driven roller each have a rotating shaft 111 and a sprocket 112, and the sprocket 112 is sleeved and fixed on the outer periphery of the rotating shaft 111. The rotating shafts 111 of the driving roller and the driven roller are rotatably passed through the side plates of the frame 13 of the conveyor 1.
[0046] The module mesh belt 12 is rotatably wound on the sprocket 112 of the active roller and the driven roller, and the teeth on the outer periphery of the sprocket 112 are meshed and transmission-connected with the grooves on the inner periphery of the module mesh belt 12 in sequence to transmit power and realize the smooth operation of the module mesh belt 12.
[0047] The modular mesh belt 12 is composed of a plurality of modular plastic or metal meshes, which are tightly connected together by a specific connection method (such as plug-in, snap-on, etc.) to form a continuous conveyor belt.
[0048] The rotating shaft 111 drives the sprocket 112 to operate by rotating, and the grooves on the inner side of the module mesh belt 12 mesh with the outer teeth of the sprocket 112. The module mesh belt 12 operates under the drive of the sprocket 112 to transfer tobacco leaves from one end to the other end, thereby realizing continuous transportation of tobacco leaves.
[0049] Preferably, the mesh is a mesh made of polypropylene. The module mesh belt 12 is provided with multiple rows along the conveying direction, and each row has multiple meshes. The meshes of each row are sequentially connected along the conveying direction by pins to form a module mesh belt 12 connected at both ends, thereby ensuring the flatness and stability of the module mesh belt 12. There are gaps between the meshes of the module mesh belt 12, and the smoke oil can drip down from the module mesh belt 12 through the gaps.
[0050] During the installation process, after the sprocket 112 is plugged into the grooves of the first row of the module mesh belt 12, it can be well plugged and matched with the grooves under each module mesh belt 12 in the subsequent transmission process to prevent wavy transmission, so that the tobacco leaves can be smoothly cut and enter the next process.
[0051] The rotating shaft 111 is usually made of metal or plastic and has certain rigidity and wear resistance.
[0052] The sprocket 112 is an oil-proof sprocket 112 .
[0053] The anti-sticking oil sprocket 112 can be meshed with the anti-sticking oil module mesh belt 12 to form a transmission link, thereby reducing the adhesion of oil stains, ensuring smooth transmission between the sprocket 112 and the module mesh belt 12, and improving the stability and service life of the device.
[0054] Furthermore, the module mesh belt 12 may be made of polypropylene (PP) or coated with a nano coating, etc. The sprocket 112 may be made of anti-sticking oil metal, polypropylene (PP), polyamide (PA), etc.
[0055] Preferably, the module mesh belt 12 is made of food-grade polypropylene (PP), which has excellent mechanical properties while also having tensile strength and bending fatigue resistance, and has low manufacturing costs, and tobacco leaf processing is safe and hygienic.
[0056] The oil-proof module mesh belt 12, sprocket 112 and the oil-proof structure of the cutter ensure that the tobacco leaves are smoothly transported and cut, which not only improves the processing efficiency, but also ensures the stability and consistency of product quality.
[0057] Since the module mesh belt 12, the sprocket 112, the upper cutter 22 and the lower cutter 23 are all designed to prevent sticking oil, oil stains will not adhere to these components during the entire conveying and cutting process, ensuring the cleanliness and efficient operation of the device.
[0058] The tobacco leaf conveying and cutting device further comprises a driving unit, which drives the roller 11 to rotate and the cutter to move.
[0059] When the conveyor 1 is started, the active roller drives the module mesh belt 12 to start rotating through the sprocket 112. The tobacco leaves on the conveyor 1 are transported forward as the module mesh belt 12 rotates. When the tobacco leaves are transported to the cutting machine position, the upper cutter 22 and the lower cutter 23 move together to cut the tobacco leaves. The cut tobacco leaves are continuously transported by the module mesh belt 12 to the next process.
[0060] Furthermore, the interior of the sprocket has a through shaft hole, the shaft hole and the rotating shaft are non-circular, and the sprocket is sleeved on the outer circumference of the rotating shaft and fixedly connected by a chuck.
[0061] The sprocket 112 and the rotating shaft 111 are connected in a stable manner, ensuring the synchronous rotation between the sprocket 112 and the rotating shaft 111, and effectively preventing the sprocket 112 from loosening or falling off during high-speed operation, thereby preventing the module mesh belt 12 from running off and causing the tobacco leaves to be cut badly. The module mesh belt 12 has a larger contact area with the rotating roller 11 during movement, thereby improving the transmission efficiency. This stable connection relationship not only further improves the stability and reliability of the conveying process, improves the stability of the device, but also further extends the service life of the device.
[0062] Furthermore, the sprocket 112 has a through shaft hole inside, the shaft hole and the outer peripheral wall of the rotating shaft 111 are squares that match each other, and the rotating shaft 111 is fixedly installed in the shaft hole. The shaft hole and the outer peripheral wall of the rotating shaft 111 can also be polygons that match each other.
[0063] The design of the square hole of the sprocket 112 and the square shaft of the rotating shaft 111 can ensure that the rotating shaft 111 is fixedly installed in the shaft hole without relative rotation, thereby improving the stability of the entire conveyor 1, avoiding the module mesh belt 12 from running off track, and thus avoiding the cutter from cutting the module mesh belt 12 and causing the cut to fall into the tobacco leaves, which can make the tobacco leaves purer.
[0064] The chuck is formed by connecting two fixed half rings and is arranged on the joint side of the sprocket to clamp the sprocket 112 and the rotating shaft 111.
[0065] Furthermore, the tobacco leaf conveying and cutting device further comprises a chain rail, which is at least partially arranged on the upper surface of the module mesh belt 12. The chain rail and the module mesh belt 12 can be synchronously operated and arranged to fix the tobacco leaves on the module mesh belt 12, so as to facilitate cutting by the cutting machine.
[0066] The chain rail is made of anti-sticking oil material.
[0067] The tobacco leaf conveying and cutting device is equipped with a rotatable chain track arranged above the module mesh belt 12. The chain track at least partially covers the module mesh belt 12 and can realize synchronous operation with the module mesh belt 12. The tobacco leaves on the module mesh belt 12 can be firmly fixed so that the cutting machine can perform precise cutting operation.
[0068] The chain rails are also made of anti-stick oil material, which not only effectively prevents oil stains from adhering, but also ensures smooth conveying and cutting processes. This detail consideration greatly improves the durability and cleanliness of the device, and further guarantees production efficiency and product quality.
[0069] Furthermore, an oil receiving structure 3 is provided at the lower part of the conveyor 1, which is located below the module mesh belt 12 and the cutter, and is used to receive the tobacco oil falling from above. The oil receiving structure 3 can receive the tobacco oil falling from above, keep the working environment clean, and facilitate centralized treatment and recycling of tobacco oil.
[0070] The oil receiving structure 3 includes oil absorbing paper, which is located directly below the module mesh belt 12 and the cutter and can receive the smoke oil dripping from above.
[0071] The oil receiving structure 3 comprises an oil receiving pan, the oil absorbing paper is arranged in the oil receiving pan, and the oil receiving pan is located directly below the module mesh belt 12 .
[0072] The oil receiving pan is detachably arranged on the frame 13. Preferably, two opposite outer edges of the opening of the oil receiving pan are slidably arranged on the inner sides of the two side plates of the frame 13.
[0073] The oil pan is designed directly below the module mesh belt 12 to receive oil or other liquids that may drip during the conveying and cutting process. The oil pan adopts a leak-proof design to ensure that the liquid will not leak out and keep the working environment clean and dry. At the same time, the capacity of the oil pan is large enough to hold more liquid, reducing the frequency of cleaning.
[0074] The oil-absorbing paper is placed in the oil pan. This paper has a strong oil absorption capacity and can quickly absorb and deal with dripping oil. The design of the oil-absorbing paper not only prevents the spread of oil, but also makes the cleaning work easier and more convenient. When the oil-absorbing paper is saturated, it can be easily replaced with a new one to keep the oil pan clean.
[0075] The above description is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
