Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, specifically to a comb roller blowing device for an air classifier. Background Technology

[0002] In the tobacco production process, to improve the quality of tobacco, flexible air classifiers are often used to remove impurities, break up clumps, adjust the length of the tobacco, and improve its filling properties. These air classifiers consist of several parts, with the combing roller being a key component used to break up tobacco clumps and remove impurities. However, after prolonged use, the combing roller accumulates tobacco residue and sticky stems, affecting the quality of the tobacco and the machine's operating efficiency.

[0003] Currently, cleaning the comb rollers mainly relies on manual operation. However, due to the small space inside the air classifier, the cleaning work is not only time-consuming and labor-intensive, but also has poor maintenance results and certain safety hazards.

[0004] In view of the above problems, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a blower device for the comb roller of an air classifier, which replaces manual cleaning and improves cleaning efficiency and safety.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A blower device for a comb roller of an air classifier is provided, comprising:

[0008] A linear guide rail is parallel to the rotation axis of the lower comb roller of the air classifier;

[0009] A slider that is slidably connected to the linear guide rail;

[0010] The blow-off assembly is fixed on the slider and located in front of the lower comb roller;

[0011] An air supply system, which is connected to the jetting assembly;

[0012] A driving component is used to drive the slider and the blowing component to perform linear reciprocating stepping motion together along the linear guide rail.

[0013] Furthermore, the air classifier comb roller blowing device also includes an adjusting connector. The linear guide rail is fixed to the frame of the air classifier through the adjusting connector, and the vertical and horizontal positions of the linear guide rail relative to the frame are adjustable through the adjusting connector.

[0014] Furthermore, the air classifier comb roller blowing device also includes a limiting component installed at the end of the linear guide rail to limit the stroke of the slider.

[0015] Furthermore, the jetting assembly includes a flow distribution module and a nozzle. The flow distribution module is provided with a nozzle hole and an air inlet. The flow distribution module is provided with an air chamber. The air chamber is connected to the nozzle hole and the air inlet respectively. The air inlet is connected to the air supply system, and the nozzle hole is connected to the nozzle.

[0016] Furthermore, the drive assembly includes a cylinder, which is kinetically connected to the slider or the jet assembly.

[0017] Furthermore, the cylinder is controlled by a three-position five-way valve.

[0018] Furthermore, the adjusting connector includes an adjusting foot, which has a vertical sidewall and a horizontal sidewall. The vertical sidewall has a vertical elongated hole, and the horizontal sidewall has a horizontal elongated hole. The vertical elongated hole cooperates with a bolt to connect the adjusting foot to the frame of the air separator, and the horizontal elongated hole cooperates with a bolt to connect the adjusting foot to a linear guide rail. By adjusting the position of the bolt in the elongated hole, the vertical and horizontal positions of the linear guide rail relative to the frame can be adjusted.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. Currently, there are no effective tools for cleaning the comb rollers of air classifiers. The air classifier comb roller blowing device of this invention solves this problem, reduces the cleaning difficulty of the comb rollers, and can effectively clean the comb rollers during the production process, ensuring product quality and equipment operating efficiency.

[0021] 2. The time required for the comb roller blowing device of this utility model to clean the air classifier is significantly shorter than that of manual blowing, which effectively shortens the maintenance time of the air classifier and accelerates the rapid label changeover time of the production line.

[0022] 3. The air classifier comb roller blowing device of this utility model eliminates the need for manual maintenance of the comb roller, reducing labor costs and avoiding potential safety hazards. Attached Figure Description

[0032] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0033] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figure 1-8 As shown, a blowing device for a comb roller of an air classifier is provided, including a linear guide rail 1, a slider 4, a blowing assembly, an air supply system (not shown in the figure), and a drive assembly. The linear guide rail 1 is parallel to the rotation axis of the lower comb roller 10 of the air classifier; the slider 4 is slidably connected to the linear guide rail 1; the blowing assembly is fixed on the slider 4 and located in front of the lower comb roller 10; the air supply system is connected to the blowing assembly; the drive assembly is used to drive the slider 4 and the blowing assembly to perform linear reciprocating stepping motion along the linear guide rail 1.

[0036] See Figure 2 The upper comb roller 18 of the air classifier has a large gap between its comb teeth, making it less prone to accumulating soot and sticky stems. However, the lower comb roller 10 has a high tooth density, which leads to the accumulation of soot and sticky stems after prolonged operation. Therefore, the comb roller cleaning device of this air classifier is installed in front of the lower comb roller 10 in the direction parallel to its rotation axis to clean the lower comb roller 10.

[0037] The blowing assembly is connected to the slider 4 by bolts 6. The slider 4 moves on the linear guide rail 1, which is positioned in front of the rotating shaft of the comb roller 10. The drive assembly is connected to the controller to control the position of the slider on the linear guide rail 1. The slider 4 moves in steps on the linear guide rail 1. For example, each stroke lasts 10 seconds, and the entire stroke is repeated 13 times. When the slider 4 reaches the end of the linear guide rail 1, it reverses direction.

[0038] It should be noted that the device uses stepping motion to spray the comb rollers at fixed points for a long time, resulting in a cleaning effect that is significantly better than manual cleaning. Moreover, the cleaning time is much faster than manual cleaning, reducing labor costs and saving maintenance time.

[0039] In one specific embodiment, the blowing assembly includes a distribution module 2 and nozzles 5. The distribution module 2 has nozzle holes 51 and air inlets 3. An air chamber is provided within the distribution module, and the air chamber is connected to both the nozzle holes 51 and the air inlets 3. The air inlets 3 are connected to the air supply system, and the nozzle holes 51 are connected to the nozzles 5. Preferably, the nozzles 5 and the blowing air chamber are connected by threads. There are a total of six nozzles. The blowing air chamber 2 has an air inlet 3, which is used to connect the blowing air chamber 2 to the air supply system. The distribution module 2 is connected to the slider 4 by bolts 6.

[0040] See Figure 3 The drive assembly includes a cylinder 17, which is connected to the slider 4 or the spray assembly. For example, the cylinder 17 is a rodless cylinder, with the flow distribution module 2 fixed to it, and the cylinder 17 performs stepping motion. The cylinder 17 is controlled by a three-position five-way valve 16, which is connected to the filter 15 via a pipeline. The filter 15 is connected to the pressure reducing valve 14 via a pipeline. Those skilled in the art will understand that cylinder drive is only one implementation method, and other drive methods, such as motors or hydraulic cylinders, can be used for the drive assembly.

[0041] A limiting member 7 is fixed at each end of the linear guide rail 1. When the slider 4 reaches the limiting member 7, it moves in the reverse direction. The overall movement trajectory of the slider 4 is a step-by-step reciprocating motion.

[0042] The linear guide rail 1 is fixed to the frame 9 of the air separator via an adjusting connector. The vertical and horizontal positions of the linear guide rail 1 relative to the frame 9 are adjustable by adjusting the connector. The adjusting connector can be designed with various structures, such as threaded structures or snap-fit ​​structures to adjust the length. These are not listed here, and those skilled in the art can design them according to actual conditions.

[0043] Preferably, the adjusting connector adopts an adjusting foot 8, which has a vertical sidewall and a horizontal sidewall. The vertical sidewall is provided with a vertical elongated hole 81, and the horizontal sidewall is provided with a horizontal elongated hole 82. The vertical elongated hole 81 cooperates with the bolt 12 and the nut 11 to connect the adjusting foot 8 to the frame 9 of the air separator. The horizontal elongated hole 82 cooperates with the bolt 13 to connect the adjusting foot 8 to the linear guide rail 1. The left and right adjustment is achieved by adjusting the position of the bolt 13 in the elongated hole, and the up and down adjustment is achieved by adjusting the position of the bolt 12 in the elongated hole.

[0044] The workflow is as follows: Start the air classifier comb roller blowing device. The blowing chamber receives gas from the air supply system. The gas is sprayed out from nozzle 5 to blow the lower comb roller. The blowing component is fixed on the cylinder. The cylinder makes a stepping motion. Each stroke lasts for 10 seconds. The entire process is repeated 13 times. When the slider 4 reaches the limit position, it moves in the reverse direction. The overall movement trajectory of the slider 4 is a stepping reciprocating motion. After cleaning is completed, turn off the switch to end the blowing.

[0045] Taking our FS43B air classifier as an example, before the installation of the air classifier's comb roller blowing device, long-term production led to the accumulation of tobacco residue and sticky stems on the comb roller, affecting the quality of the tobacco and reducing equipment production efficiency. Furthermore, after production, manual cleaning of the air classifier's comb roller using compressed air was required, resulting in long maintenance times, high labor intensity, and poor maintenance effectiveness, impacting product quality. After installing the air classifier's comb roller blowing device, production trials have shown excellent results: during production, the comb roller can be cleaned regularly, ensuring tobacco quality. Simultaneously, manual maintenance of the comb roller is eliminated, reducing labor costs and saving maintenance time. The maintenance effect is also better than manual maintenance, ensuring the intrinsic quality of the product; at the same time, potential safety hazards are avoided, protecting the health of employees.

[0046] The above are merely preferred embodiments of this utility model and are illustrative rather than restrictive. The structure and connection methods of the components in this utility model can be varied. Any equivalent transformations and improvements made based on the technical solution of this utility model should not be excluded from the protection scope of this utility model.
