Description

Technical Field

[0001] The present application relates to the technical field of conveyor belts, and in particular to a tobacco conveying assembly. Background Art

[0002] Conveyor belts are widely used in industrial production, logistics and warehousing, retail, healthcare, and agriculture. Conveyor belts are composed of a combination of fabric and PVC or PU / PE layers, bonded together through a multi-layer process. Different layers and materials are used for different applications to achieve optimal conveying performance, while reducing labor and transportation costs and improving efficiency.

[0003] Furthermore, conveyor belts may be adjusted to different angles with the ground to suit different applications and scenarios, and their surfaces may also feature raised structures made of different materials and shapes to accommodate these angles. In the industrial sector, a "human"-shaped raised structure is installed on the surface of the conveyor belt during tobacco transport to increase friction on the conveyor belt surface, prevent tobacco accumulation, and improve conveyor efficiency.

[0004] However, in the above method, a raised structure is provided on the surface of the tobacco conveyor belt, and the raised structure is in the shape of a "human" strip. Although it has an anti-slip effect during the conveying process, tobacco may be stuck in the seam during the conveying process. Since tobacco is transmitted with humidity, it may breed harmful substances if it is stuck in the "human" strip-shaped raised structure for a long time. In addition, during the rotation of the conveyor belt, the "human" strip-shaped raised structure is prone to breakage when it rotates to a bend, which greatly reduces the use time and reduces the practicality.

[0005] In order to solve the above problems, the existing technology changes the shape of the raised part on the surface of the conveyor belt, and changes the "human" strip-shaped raised structure into a dot-shaped raised structure, thereby avoiding the situation where the raised structure breaks when rotating to a curve. At the same time, when the dot-shaped raised structure cannot effectively provide friction, the dot-shaped raised structure is arranged more densely to increase the friction on the tobacco and improve the transmission efficiency.

[0006] However, the surface of the conveyor belt is densely provided with dot-shaped protrusion structures. Small tobacco shreds may adhere to the dot-shaped protrusion structures in the opposite direction of the conveyor belt's operation, which may breed harmful substances over a long period of time. Utility Model Content

[0007] The purpose of this application is to solve the problem of how to improve the transmission efficiency of tobacco shreds on tobacco conveyor belts in the existing technology, and how to avoid tobacco shreds from adhering to and damaging the tobacco shreds on the conveyor belts during the transmission process. Therefore, this application provides a tobacco shreds transmission component, which makes the conveyor belt light and durable by making it two-layer glue and two-layer cloth, and increases its tensile and wear resistance. The raised structure on the surface of the conveyor belt is transformed into a long strip with its length parallel to the running direction, which solves the problem of the raised structure being damaged at the bend and the problem of tobacco shreds adhering to the conveyor belt, prolongs its service life, improves the practicality of the conveyor belt, and improves the transmission efficiency of tobacco shreds.

[0008] An embodiment of the present application provides a tobacco conveying assembly, comprising multiple transmission shafts and a conveyor belt arranged around the multiple transmission shafts; the conveyor belt is arranged to be multi-layered, the upper layer of the conveyor belt is arranged to be a gelatin, and the gelatin is provided with multiple protrusion structures; the protrusion structure is arranged to be a long strip, and the length direction of the protrusion structure is parallel to the conveying direction of the conveyor belt.

[0009] By adopting the above technical solution, multiple transmission shafts are set to increase the stability and reliability of the conveyor belt during the transmission process, and the power transmission is realized by rolling friction with high efficiency. The multi-axis transmission has low noise and effectively avoids the noise impact. At the same time, it is easy to maintain the transmission equipment; the conveyor belt is set to be multi-layered and contains a rubber layer to increase the tensile resistance and wear resistance of the conveyor belt; the top layer of the conveyor belt is set to a rubber layer to increase the friction with the tobacco and reduce the possibility of the tobacco slipping; a raised structure is added to the surface of the conveyor belt to increase the friction with the tobacco, so as to minimize the tobacco slipping from the conveyor belt during the upward slope transmission, thereby improving the operation and transmission efficiency of the tobacco.

[0010] Furthermore, by limiting the raised structure to a long strip shape, and aligning the length direction of the long strip raised structure with the conveying direction of the conveyor belt, while increasing the friction on the tobacco, it effectively avoids the raised structure being damaged by external tension when the transmission shaft turns, thereby improving the practicality of the conveyor belt, extending the service life of the conveyor belt, and improving the operating and conveying efficiency of the tobacco.

[0011] In some embodiments, a curved gentle slope is provided around the convex structure.

[0012] By adopting the above technical solution, the periphery of the raised structure is set as an arc-shaped gentle slope, which increases the effective friction and effectively avoids the sharp end of the raised structure damaging the tobacco during the transmission process. It also avoids the raised structure colliding with the sharp end during the transmission process and damaging the tobacco to a great extent, and avoids the pollution of other tobacco caused by long-term cleaning and use, which further affects human health.

[0013] In some embodiments, the plurality of protruding structures are arranged in multiple columns, the arrangement direction of the plurality of protruding structures in each column is parallel to the conveying direction of the conveyor belt, and the plurality of protruding structures in each column are evenly spaced.

[0014] By adopting the above technical solution, the arrangement design of the raised structures is regularized by arranging the raised structures in multiple columns, which further improves the friction on the tobacco and is more conducive to transmission; the arrangement direction of the multiple raised structures in each column is parallel to the transmission direction of the conveyor belt, and the raised structures in each column are evenly spaced, which improves the transmission efficiency of the tobacco while avoiding damage to the raised structures when rotating to the corners.

[0015] In some embodiments, the conveyor belt is provided with multiple rows of protruding structures, and among the multiple rows of protruding structures, the protruding structures in two adjacent rows are staggered.

[0016] By adopting the above-mentioned technical solution, multiple rows of raised structures are provided on the conveyor belt, and among the multiple rows of raised structures, the raised structures of two adjacent rows are staggered to effectively utilize the spacing space between the raised structures, thereby increasing the friction density and thus increasing the friction on the tobacco. At the same time, the parallelism of the tobacco is improved, avoiding accumulation and congestion between the tobacco, and improving the transmission efficiency of the tobacco.

[0017] In some embodiments, the conveyor belt has a two-cloth and two-rubber structure, the two cloths are made of industrial yarn, and the two rubbers are made of PU / PE / PVC.

[0018] By adopting the above technical solution, the conveyor belt is made light and durable by setting a two-rubber and two-cloth structure, and the tensile resistance and wear resistance of the conveyor belt are increased, thereby reducing the cost of use; the material of the two rubbers is set to PU / PE / PVC, which has good plasticity, high acid and alkali resistance, good thermal decomposition resistance, stable chemical properties, and good heat resistance, which improves practicality. At the same time, PU / PE / PVC itself is non-toxic and odorless, and can directly contact with tobacco, thereby improving applicability and service life.

[0019] In some embodiments, the radius of the multiple transmission shafts is 10cm to 15cm, the height of the raised structure is 1.5mm to 2.5mm, the width is 4mm to 8mm, and the length is 15mm to 30mm. The total thickness of the conveyor belt and the raised structure is 4mm to 10mm.

[0020] By adopting the above technical solution, the radius of multiple transmission shafts is set to 10cm~15cm, which increases the rotation angle of the conveyor belt and reduces the rotation angle of the long strip protrusion structure during rotation, thereby avoiding to the greatest extent the damage of the long strip protrusion structure due to excessive external tension during the transmission process; the height of the long strip protrusion structure is set to 1.5mm~2.5mm, so that its friction with tobacco is suitable and it is convenient to transmit tobacco; the width of the long strip protrusion structure is set to 4mm~8mm, and the length is set to 15mm~30mm, which is convenient to set according to the width rule of the conveyor belt, effectively improving the friction with tobacco, and at the same time avoiding the accumulation of tobacco during transmission, thereby improving the transmission efficiency of tobacco; further, the total thickness of the conveyor belt and the long strip protrusion structure is set to 4mm~10mm, which makes the conveyor belt more lightweight and convenient when transmitting tobacco, increases the tensile resistance and wear resistance of the conveyor belt, and improves the transmission efficiency.

[0021] Other features and corresponding beneficial effects of the present invention are described in the latter part of the specification, and it should be understood that at least some of the beneficial effects become obvious from the description in this specification.

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0038] See Figures 1 to 5 , Figure 1 A schematic diagram of a top view of a raised structure on a conveyor belt provided in an embodiment of the present application; Figure 2 This is a schematic diagram of an enlarged structure of a protrusion provided in an embodiment of the present application; Figure 3 A schematic diagram of a side view of a protruding structure provided in an embodiment of the present application; Figure 4 A schematic diagram of the structure of a conveyor belt provided in an embodiment of the present application running on a transmission shaft; Figure 5 This is a schematic diagram of the structure of two adhesives and two cloths provided in an embodiment of the present application.

[0039] For example, see Figures 1 to 5 As shown, an embodiment of the present application provides a tobacco conveying assembly, including multiple transmission shafts 1 and a conveyor belt 2 arranged around the multiple transmission shafts 1; the conveyor belt 2 is arranged to be multi-layered, and the upper layer of the conveyor belt 2 is arranged to be a gelatin 21, and a plurality of protrusion structures 23 are arranged on the gelatin 21; the protrusion structure 23 is arranged to be a long strip, and the length direction of the protrusion structure 23 is parallel to the conveying direction of the conveyor belt 2.

[0040] Those skilled in the art will appreciate that the transmission apparatus, equipped with multiple drive shafts 1, needs to ensure increased stability and reliability of the conveyor belt 2 during the conveying process. The power transmission achieved by rolling friction is highly efficient, with multi-shaft transmission providing low noise levels and effectively preventing noise impacts. This also facilitates maintenance of the conveyor apparatus. For example, the conveyor apparatus may comprise two drive shafts 1 at either end, with the middle portion suspended by a bracket and tensioned at both ends. Alternatively, three or more drive shafts 1 may be arranged in a line. The conveyor belt 2 may be constructed with multiple layers and contain a rubber layer 21 to enhance its tensile strength and wear resistance. Examples include two layers of rubber and two layers of fabric, three layers of rubber and two layers of fabric, or three layers of rubber and three layers of fabric, or a belt-like structure. The top layer of the conveyor belt 2, formed of a rubber layer 21, needs to enhance friction with the tobacco and reduce the risk of tobacco slipping. For example, materials such as rubber or nylon are needed. Protruding structures 23 are added to the surface of the conveyor belt 2 to ensure increased friction with the tobacco, minimizing the risk of tobacco slipping off the conveyor belt 2 during its upward incline transport, thereby improving tobacco conveying efficiency. For example, a concave structure may be provided on the conveyor belt 2 , or a partition may be provided on the conveyor belt 2 .

[0041] Furthermore, by limiting the protrusion structure 23 to a long strip shape, and with the length direction of the long strip protrusion structure 23 parallel to the conveying direction of the conveyor belt 2, it is necessary to ensure that while increasing the friction on the tobacco, the protrusion structure 23 is effectively prevented from being damaged by external tension when the transmission shaft 1 turns, thereby improving the practicality of the conveyor belt 2, extending the service life of the conveyor belt 2, and improving the operating efficiency of the tobacco. For example, the protrusion structure 23 can be set as a dot-shaped protrusion structure 23, the long strip protrusion structure 23 can be a rectangular long strip protrusion structure 23, an elliptical protrusion structure 23, or a cone-shaped protrusion structure 23 with an elliptical tip.

[0042] In one embodiment, an arc-shaped gentle slope 231 is provided around the periphery of the protruding structure 23 .

[0043] Those skilled in the art will appreciate that by providing the raised structure 23 with an arc-shaped gentle slope 231, it is necessary to ensure that effective friction is increased while minimizing the risk of the raised structure 23 colliding with the sharp end during transport and damaging the tobacco. Furthermore, it is necessary to prevent tobacco or fine tobacco impurities from adhering to the shaded portion of the raised structure 23 in the opposite direction of transport, thereby preventing contamination of other tobacco due to long-term use without cleaning, which could further affect human health. For example, a surface slope could be provided around the raised structure 23, or a raised arc could be provided around the raised structure 23, or the raised structure 23 could be directly configured as a semi-ellipse.

[0044] In one embodiment, the plurality of protruding structures 23 are arranged in multiple columns, the arrangement direction of the plurality of protruding structures 23 in each column is parallel to the conveying direction of the conveyor belt 2 , and the plurality of protruding structures 23 in each column are evenly spaced.

[0045] Those skilled in the art will appreciate that by arranging the raised structures 23 in multiple rows, the raised structures 23 are arranged in a regular pattern, further improving the friction on the tobacco and facilitating its transport. The arrangement direction of the multiple raised structures 23 in each row is parallel to the transport direction of the conveyor belt 2, and the raised structures 23 in each row are evenly spaced apart. This is necessary to ensure that the raised structures 23 are not damaged when rotating around a bend, while also improving the transport efficiency of the tobacco. For example, the long strip-shaped raised structures 23 are arranged side by side without any spacing (similar to speed bumps on the road).

[0046] In one embodiment, the conveyor belt 2 is provided with multiple rows of raised structures 23, and the raised structures 23 in two adjacent rows are staggered. By providing multiple rows of raised structures 23 on the conveyor belt 2 and staggering the raised structures 23 in two adjacent rows, the spaces between the raised structures 23 are effectively utilized, thereby increasing the friction density and thus the friction on the tobacco. This also improves the parallelism of the tobacco, avoids accumulation and congestion between the tobacco, and improves the efficiency of tobacco conveyance.

[0047] In one use case, the conveyor belt 2, with its tilted angle, rotates on multiple drive shafts 1, evenly placing shredded tobacco (some still wet and damp) on the conveyor belt 2. As the conveyor belt 2 moves upward, the tobacco passes through the anti-slip adhesive 21 and the long, raised structures 23, preventing it from slipping. Some tobacco will slip under each row of raised structures 23, only to be caught by the staggered rows of raised structures 23 in the next row. When the raised structures 23 of the conveyor belt 2 rotate around a curve, their outer surfaces maintain tension, preventing them from being easily damaged.

[0048] In one embodiment, the conveyor belt 2 is a two-cloth and two-rubber structure, the two cloth materials are industrial yarn, and the two rubber materials are PU / PE / PVC.

[0049] Those skilled in the art will appreciate that by configuring the conveyor belt 2 with a two-rubber, two-cloth structure, it is necessary to ensure that the conveyor belt 2 is lightweight and durable during the conveying process, increase its tensile and wear resistance, and reduce its operating costs. For example, the conveyor belt 2 may be configured with three rubbers and two cloths or three rubbers and three cloths. The two rubbers are constructed of PU / PE / PVC, which has good plasticity, high acid and alkali resistance, good thermal decomposition resistance, stable chemical properties, and good heat resistance, thereby improving practicality. Furthermore, PU / PE / PVC is non-toxic and odorless, and can directly contact tobacco, thereby improving its applicability and service life.

[0050] In one embodiment, the radius of the multiple transmission shafts 1 is 10cm-15cm, the height of the protruding structure 23 is 1.5mm-2.5mm, the width is 4mm-8mm, and the length is 15mm-30mm. The total thickness of the conveyor belt 2 and the protruding structure 23 is 4mm-10mm.

[0051] It will be understood by those skilled in the art that when the radius of the multiple transmission shafts 1 is set to 10cm to 15cm, it is necessary to ensure that the rotation angle of the conveyor belt 2 is increased, the rotation angle of the long strip-shaped protruding structure 23 is reduced during rotation, and the long strip-shaped protruding structure 23 is avoided to the greatest extent possible due to excessive external tension during the transmission process. For example, the radius of the multiple transmission shafts 1 is 10cm to 15cm. When the height of the long strip-shaped protruding structure 23 is set to 1.5mm to 2.5mm, it is necessary to ensure that the friction of the protruding structure 23 on the tobacco is suitable to facilitate the transmission of the tobacco. For example, the height of the protruding structure 23 is set to 2mm or 1.5mm. The width of the long strip-shaped raised structure 23 is set to 4mm to 8mm, and the length is set to 15mm to 30mm. The interval between two adjacent long strip-shaped raised structures 23 in each row is set to 20 to 50mm. It is necessary to ensure that it is easy to set according to the width rule of the conveyor belt 2, effectively improve the friction on the tobacco, and at the same time avoid the accumulation of tobacco during transportation, thereby improving the transportation efficiency of tobacco. The total thickness of the conveyor belt 2 and the long strip-shaped raised structure 23 is further set to 4mm to 10mm. It is necessary to ensure that the conveyor belt 2 is lighter and more convenient when transporting tobacco, increase the tensile strength and wear resistance of the conveyor belt 2, and improve the transportation efficiency. For example, the total thickness of the conveyor belt 2 and the long strip-shaped raised structure 23 is 5mm or 6mm.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
