Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production equipment, in particular to a belt cleaning device and a belt conveyor. Background Art

[0002] In the tobacco silk production line, the belt conveyor is used as an auxiliary equipment to transport tobacco leaves and other materials. In the process of transporting tobacco leaves and other materials, tobacco leaves will remain on the belt of the belt conveyor, thus affecting the operation of the belt conveyor and the quality of tobacco products. In order to keep the belt surface clean, a belt cleaning device is usually installed on the belt conveyor to clean the belt surface. Figure 6 The structure diagram of the belt cleaning device in the prior art is shown as follows: Figure 6 As shown, the belt cleaning device in the prior art includes a brush roller 7, on which a plurality of brush plates 71 extending along its axial direction are provided, and each brush plate 71 is arranged at intervals along the circumference of the brush roller 7. The brush roller 7 can rotate along its own axis so that each brush plate 71 contacts the belt in turn to clean the belt.

[0003] However, in the actual production process, especially in a high humidity working environment, the moisture content of tobacco leaves and other materials will become relatively high, which will cause a certain degree of adhesion between them, resulting in material agglomeration between the two brush plates 71, thereby bringing the risk of tobacco insects and making it difficult to ensure the quality of tobacco products. Utility Model Content

[0004] The utility model aims to solve the technical problem that the existing belt cleaning brush roller is prone to adhering too much material, which breeds tobacco insects and reduces the quality of tobacco products. The utility model provides a belt cleaning device and a belt conveyor, which can reduce the agglomeration of materials on the brush roller, thereby reducing the probability of breeding tobacco insects and ensuring the quality of tobacco products.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a belt cleaning device for cleaning the belt of a belt conveyor, and the belt cleaning device comprises:

[0008] With the above technical solution, when the brushes on the brush roller come into contact with the belt surface, the material on the belt surface will fall between the brushes. Figure 6 The belt cleaning device shown in the application is provided with multiple brush rollers along the axial direction of the rotating shaft, and the brush pieces on two adjacent sections of the brush rollers are arranged in a staggered manner, so that the cleaning time of the belt by the two adjacent brush rollers is not synchronized, and the cleaned materials will not fall onto the two adjacent brush rollers at the same time, so that the material agglomeration between the two brush pieces on a single brush roller is relatively small, and will not adhere to the material agglomeration on the adjacent brush roller. When the brush rollers rotate with the rotating shaft, the material between the brush pieces is easily separated from the brush roller, thereby reducing the probability of tobacco insect breeding and ensuring the quality of tobacco products.

[0033] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 and Figure 2As shown, an embodiment of the utility model provides a belt cleaning device for cleaning the belt of a belt conveyor. The belt cleaning device includes a rotating shaft 11 and a plurality of brush rollers 2.

[0035] Specifically, the rotation axis 11 is along a first direction (eg Figure 1 The first direction is the width direction of the belt 5, and both ends of the rotating shaft 11 are rotatably connected to the frames 4 on both sides of the belt.

[0036] A plurality of brush rollers 2 are sequentially sleeved on the rotating shaft 11 along a first direction, and each brush roller 2 is provided with a plurality of brush plates 21 extending along the first direction. The brush plates 21 are arranged on the circumferential surface of the brush roller 2 at intervals along the circumference of the brush roller 2, and the brush plates 21 can contact the surface of the belt 5 in sequence as the brush roller 2 rotates; the brush plates 21 on two adjacent brush rollers 2 are staggered one by one along the circumference of the brush roller 2.

[0037] The applicant has fully considered the problems that may arise during the cleaning process of the belt cleaning device. Figure 6 In the existing belt cleaning device shown, the brush sheet 71 on the brush roller 7 is arranged to extend from one end of the brush roller 7 to the other end. When the brush sheet 71 on the brush roller 7 contacts the surface of the belt 5, the material on the surface of the belt 5 will fall between the two brush sheets 71, and the agglomeration formed by the material will extend from one end of the brush roller 7 to the other end, so that the agglomeration of the material is relatively large, resulting in the agglomeration being difficult to detach from the brush roller 7 during the rotation of the brush roller 7. However, the belt cleaning device provided by the present application (such as Figure 2 (As shown) by arranging a plurality of brush rollers 2 along the axial direction of the rotating shaft 11, and staggering the brush plates 21 on two adjacent sections of the brush rollers 2, the volume of the agglomerates on the brush roller 2 can be reduced, so that the agglomerates can be easily detached from the brush roller 2 during the rotation of the brush roller 2.

[0038] In order to enable those skilled in the art to better understand, the technical solution of the present application is specifically described below through an embodiment. Figure 2In the belt cleaning device provided in the present application, a brush roller 2a, a brush roller 2b and a brush roller 2c are sequentially sleeved on the rotating shaft 11, wherein the brush pieces 21b on the brush roller 2b are alternately arranged with the brush pieces 21a on the brush roller 2a and the brush pieces 21c on the brush roller 2c, that is, the two ends of the brush piece 21b are respectively aligned with the gap between the two brush pieces 21a and the gap between the two brush pieces 21c. By staggering the brush pieces 21b with the brush pieces 21a and the brush pieces 21c, respectively, the cleaning time of the brush rollers 2a, 2b and 2c on the belt 5 can be made asynchronous, that is, when the brush piece 21b contacts the belt 5, the brush pieces 21a and 21c will not contact the belt 5, so the cleaned materials will not fall onto the brush rollers 2a, 2b and 2c at the same time, thereby reducing or even avoiding the adhesion of the material agglomeration on the brush roller 2b with the material agglomeration on the brush rollers 2a and 2c, and the material agglomeration between the two brush pieces 21 on a single brush roller 2 is relatively small and light in weight. When the rotating shaft 11 rotates, the materials on each brush roller 2 are easily separated from the brush roller 2, thereby reducing the probability of breeding tobacco insects and ensuring the quality of tobacco products.

[0039] Furthermore, the belt cleaning device further comprises a transmission mechanism 3 , which is disposed at one end of the rotating shaft 11 and is used to drive the rotating shaft 11 and the brush roller 2 to rotate along the circumferential direction of the rotating shaft 11 .

[0040] Furthermore, the transmission mechanism 3 includes two sprockets 31 and a chain 32 , wherein one sprocket 31 is connected to the rotating shaft 11 , and the other sprocket 31 is connected to the driving roller 6 , and the chain 32 is sleeved on the two sprockets 31 .

[0041] Specifically, in the process of transporting tobacco leaves and other materials, the belt conveyor places the materials on the belt 5, and transports the materials by rolling the belt 5. The belt conveyor is provided with a driving roller 6, which can drive the belt 5 to run. The utility model is to install a brush roller 2 on the belt conveyor, and the specific installation method is to first sleeve a plurality of brush rollers 2 on the rotating shaft 11 in sequence along the axial direction of the rotating shaft 11, and stagger the brush pieces 21 on two adjacent brush rollers 2 one by one along the circumferential direction of the brush roller 2. Subsequently, the operator fixes each brush roller 2 on the rotating shaft 11, and rotatably connects the two ends of the rotating shaft 11 to the frame 4 of the belt conveyor, so that the brush pieces 21 on the brush roller 2 are in contact with the belt 5, and at the same time, connects a sprocket 31 to the rotating shaft 11, and the other sprocket 31 to the driving roller 6, and then connects the two sprockets 31 through a chain 32. When the belt conveyor is working, the driving roller 6 drives the belt 5 to roll, and the rotating shaft 11 and the brush roller 2 rotate under the drive of the chain 32, so that the brush pieces 21 clean the surface of the belt 5. During the cleaning process, tobacco leaves and other materials that fall between the brush pieces 21 can fall off the brush rollers 2 as the brush rollers 2 rotate.

[0042] Specifically, the belt cleaning device also includes:

[0043] Two connecting shafts 12 are respectively arranged at two ends of the rotating shaft 11, and the axes of the two connecting shafts 12 coincide with the axis of the rotating shaft 11, and one of the connecting shafts 12 is connected to the sprocket 31;

[0044] Two bearing seats 13 are respectively mounted on the frame 4 at both sides of the belt 5 , and the two connecting shafts 12 are respectively inserted into the bearings of the two bearing seats 13 .

[0045] When implementing it, refer to Figure 3 Each brush roller 2 is fixedly mounted on the rotating shaft 11 by a bolt 22. The bolt 22 can fix each brush roller 2 to prevent each brush roller 2 from rotating relative to the rotating shaft 11, thereby improving the stability of the belt cleaning device.

[0046] In some embodiments, Figure 4 and Figure 5 As shown, the circumferential surface of each brush roller 2 is provided with a plurality of slots 24 extending axially along the rotating shaft 11, and an arc surface 25 with a certain curvature is constructed between each slot 24. The arc 25 can receive the material swept by the brush sheet 21, so that the material falls into the next process during the rotation of the brush roller 2.

[0047] Furthermore, a base 211 matching the slot 24 is provided at the bottom of each brush piece 21 , and the base 211 of the brush piece 21 can be inserted into the slot 24 along the axial direction of the rotating shaft 11 .

[0048] The belt cleaning device of the utility model is provided with a slot 24 on the brush roller 2 and a base 211 matching the slot 24 is arranged at the bottom of the brush sheet 21 , so that an operator can replace the brush sheet 21 easily.

[0049] Furthermore, a separator 23 is provided between the end surfaces of two adjacent brush rollers 2 to limit the axial movement of the brush sheet 21 installed on the brush roller 2 along the rotating shaft 11 .

[0050] Furthermore, the belt cleaning device further comprises a material collecting hopper (not shown in the figure), which is arranged below the brush roller 2. The material collecting hopper collects the material dropped from the brush roller 2, and the operator can transport the collected material to the next process for reuse.

[0051] Based on the same concept, an embodiment of the utility model also provides a belt conveyor, which includes a frame 4, a belt 5, a driving roller 6 and a driven roller, and a combination Figure 1-5 In any of the belt cleaning devices described, the belt 5 is sleeved on a driving roller 6 and a driven roller.

[0052] The belt conveyor of the utility model is configured such that the driving roller 6 can drive the belt 5 and the belt cleaning device at the same time, thereby cleaning the materials on the belt 5 and saving the operation cost.

[0053] Specifically, there are multiple belt cleaning devices, and each belt cleaning device is sequentially arranged at intervals along the length direction of the belt 5. Multiple belt cleaning devices clean the belt 5, which can improve the cleaning effect of the belt cleaning devices.

[0054] It should be noted that, in the examples and description of the present utility model, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise one" do not exclude the presence of other identical elements in the process, method, article or device including the elements.
