Description

Technical Field

[0001] The invention relates to the technical field of tobacco shred conveying, in particular to a tobacco shred conveying belt. Background Art

[0002] The tobacco conveyor belt is an indispensable part of the tobacco processing production line. The design and operation of the conveyor belt directly reflect the smoothness of the entire production process and the quality standard of the final tobacco product. This feed belt is not only a bridge for tobacco from the raw material area to the processing area, but also the key to ensuring production continuity, reducing material loss and improving product consistency.

[0003] However, the sides of the conveyor belt are usually provided with side edges of a certain height. The main function of these side edges is to guide the tobacco to flow along a predetermined path and prevent it from deflecting or spilling during the transmission process. However, in actual operation, when the conveyor belt moves forward at a stable speed, the tobacco often inevitably comes into contact with the side edges. This contact becomes more frequent and intense due to the effect of friction, especially in the case of high speed or large-scale feeding. The tobacco will adhere to each other due to mutual squeezing and friction, and gradually form agglomerations. Therefore, we propose a new type of tobacco conveyor belt. Summary of the invention

[0004] 1. Technical issues to be solved

[0033] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0034] The present invention provides a technical solution:

[0035] See also Figures 1 to 5A tobacco conveyor belt comprises a concave frame 1, and an anti-edge mechanism 2 is arranged inside the concave frame 1.

[0036] The anti-edge mechanism 2 includes a mounting groove 21, inside which an air collecting box 22 is fixedly mounted, an inner cavity of the air collecting box 22 is fixedly mounted with an exhaust plate 23, an inner part of the exhaust plate 23 is provided with an exhaust port 24, a diversion air duct 25 is fixedly mounted on the back of the air collecting box 22, a main flow air duct 26 is fixedly mounted on the end of the diversion air duct 25 away from the air collecting box 22, a fan 27 is fixedly mounted on the left end of the main flow air duct 26, a plugging head 28 is fixedly mounted on the right end of the main flow air duct 26, and an air guide cover 29 is fixedly mounted on the inner side of the air collecting box 22. The anti-edge mechanism 2 is carefully arranged inside the conveyor belt 32, the core of which is composed of the air collecting box 22 carried by the mounting groove 21, the box is embedded with an exhaust plate 23, and the exhaust ports 24 are densely distributed on it to ensure uniform air distribution. The back of the air collecting box 22 is cleverly connected to the diversion air guide 25, which converges to the main flow air guide 26 and is driven by the high-efficiency fan 27 to form a strong airflow. The plugging head 28 ensures the unidirectional flow of the airflow, while the air guide cover 29 accurately guides the airflow to the key side area of ​​the tobacco transmission, forming an invisible air barrier.

[0037] Furthermore, there are several exhaust ports 24, which are evenly distributed on the exhaust plate 23. By evenly arranging the exhaust ports 24 on the exhaust plate 23, a dense and efficient airflow network is formed. This layout not only ensures the uniformity of the airflow, but also enables the air to accurately penetrate into every tiny corner of the tobacco transmission, effectively reducing the chance of tobacco contacting the side, thereby fundamentally curbing the occurrence of adhesion and agglomeration.

[0038] Furthermore, there are several flow-dividing air ducts 25, and the several flow-dividing air ducts 25 are evenly distributed on the main flow air duct 26. By providing several flow-dividing air ducts 25, and these flow-dividing air ducts 25 are evenly distributed on the main flow air duct 26, the air sucked from the main flow air duct 26 can be more evenly distributed to the air collecting box 22, thereby ensuring that the air pressure and wind speed in each air collecting box 22 remain consistent. This even distribution not only improves the efficiency and stability of air flow, but also avoids the problem of insufficient or excessive air volume in a local area due to uneven airflow.

[0039] Furthermore, the fan 27 is threadedly connected to the recessed frame 1. By adopting the threaded connection between the fan 27 and the recessed frame 1, this design not only realizes the rapid installation and removal of the fan 27, but also greatly enhances the stability of the connection.

[0040] Furthermore, the air guide cover 29 is in a fan shape as a whole, and the air outlet of the air guide cover 29 faces downward. The air blown out from the exhaust port 24 can form a concentrated and directional airflow by designing the air guide cover 29 in a fan shape as a whole and arranging the air outlet downward. Under the guidance of the air guide cover 29, the airflow can more accurately act on the key area where the tobacco shreds contact the side of the conveyor belt 32, effectively avoiding the reduction of efficiency caused by air diffusion.

[0041] Furthermore, a conveying mechanism 3 is provided on the inner side of the recessed frame 1, and the conveying mechanism 3 includes a main roller 31 rotatably connected to the inner side of the recessed frame 1, the outer side of the main roller 31 is transmission-connected to a conveying belt 32, the inner side of the right end of the conveying belt 32 is transmission-connected to a slave roller 33, and a motor 34 is fixedly installed on one end of the main roller 31 close to the fan 27, and a motor mounting plate 35 is provided at the bottom of the motor 34. The motor 34 provides a powerful power drive, so that the rotation of the main roller 31 directly drives the outer conveying belt 32 to circulate, forming a continuous and stable transmission path.

[0042] Furthermore, the slave roller 33 is rotatably connected to the recessed frame 1 and is located inside the recessed frame 1 , and the slave roller 33 assists the conveyor belt 32 in performing normal transmission.

[0043] Furthermore, the motor mounting plate 35 is fixedly connected to the recessed frame 1 , and the motor mounting plate 35 is fixedly connected to the motor 34 . The motor 34 can be installed and fixed through the motor mounting plate 35 , ensuring that the motor 34 can be in a specified position and maintain normal operation.

[0044] Furthermore, the conveyor belt 32 is located below the air guide cover 29. By arranging the conveyor belt 32 below the air guide cover 29, a perfect combination of the air barrier and the tobacco transmission path is achieved. The fan-shaped design of the air guide cover 29 and the downward air outlet enable the airflow generated by the fan 27 to directly and efficiently act on the tobacco on the conveyor belt 32, especially those areas that are prone to contact with the side and produce adhesion.

[0045] Furthermore, the air guide cover 29 can also be provided with a plurality of air holes, and the air holes are evenly distributed on the side walls of the air guide cover 29 along the direction of the conveyor belt. With such a configuration, the wind can be better blown toward the conveyor belt. Of course, the wind force at this time should be set very small to avoid the wind force that blows the tobacco shreds away and floats. Preferably, a layer of filter is provided at the air hole to prevent the tobacco shreds from blocking the air hole. The filter is a metal filter, and the surface of the metal filter can also be sprayed with a nano material layer, and the nano material layer here can be an ultra-smooth nano material layer, which further prevents the tobacco shreds from being adsorbed to the filter surface of the air hole during transportation.

[0046] Furthermore, a support mechanism 4 is provided at the bottom of the recessed frame 1, and the support mechanism 4 includes support rods 41 fixedly installed at the four corners of the bottom of the recessed frame 1, and a foot plate 42 is fixedly installed at the lower end of the support rod 41. The entire device is supported by the support rod 41, and the foot plate 42 increases the contact area with the ground, thereby improving the overall stability.

[0047] When used specifically, the working principle of the present invention is as follows:

[0048] Startup and driving phase:

[0049] When a tobacco conveyor belt needs to be started on the production line, the motor 34 is first started through the control system. The motor is firmly fixed on the recessed frame 1 through the motor mounting plate 35 to ensure the stability of the motor 34 during operation. After the motor 34 is started, its power is directly transmitted to the main roller 31, driving the main roller 31 to start rotating. The main roller 31 is the core component of the conveying mechanism 3. Its rotational movement drives the outer conveyor belt 32 to move synchronously through friction. The inner side of the other end of the conveyor belt 32 is connected to the slave roller 33 by transmission to form a closed loop belt, ensuring that the tobacco can be continuously and stably transmitted along the predetermined path.

[0050] Tobacco transmission and anti-adhesion mechanism:

[0051] As the conveyor belt 32 is started, the tobacco is placed on the conveyor belt 32 and is transferred from one end to the other end as it moves. In this process, in order to prevent the tobacco from sticking and clumping due to friction with the side, the fan 27 is started synchronously. The fan 27 efficiently inhales air through the main flow air duct 26 and evenly distributes the air to the air collection box 22 through the branch air duct 25. The design of the air collection box 22 allows the air to be concentrated and accelerated, and is blown out finely through the exhaust ports 24 evenly distributed on the exhaust plate 23. The number and distribution of these exhaust ports 24 have been carefully calculated to ensure that the air can evenly cover the key areas of tobacco transmission.

[0052] Air Barriers and Guides:

[0053] The blown air is then finely guided by the air guide 29. The fan-shaped design of the air guide 29 and its downward air outlet allow the air to be accurately blown to the side areas of the conveyor belt 32 where adhesion is prone to occur. This design not only reduces the direct contact between the tobacco and the side, but also effectively blows away the adhesion between the tobacco through the blowing effect of the airflow, preventing the occurrence of agglomeration. At the same time, the formation of the air barrier also reduces the friction coefficient of the tobacco during the transmission process, further improving the smoothness and efficiency of the transmission.

[0054] Support and stability:

[0055] The entire tobacco conveying system is firmly installed on the production line through the recessed frame 1 and the support mechanism 4 at the bottom thereof. The support mechanism 4 includes support rods 41 fixedly installed at the four corners of the bottom of the recessed frame 1 and footrests 42 at the lower ends of the support rods 41, which provide solid support and stability for the entire system. This design ensures that the conveyor belt can maintain stable operation even in the case of high-speed or large-volume feeding, reducing tobacco scattering and quality problems caused by vibration or shaking.

[0056] In summary, the tobacco conveyor belt of the present invention effectively solves the problems of tobacco sticking and clumping in traditional conveyor belts through the innovative anti-edge mechanism 2 and air barrier design, improves the continuity of the production line and product consistency, and ensures the quality of the final tobacco product.

[0057] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
