Description

Technical Field

[0001] This application relates to the field of cigarette manufacturing, and more particularly to a hemp fiber removal machine and cigarette manufacturing equipment. Background Technology

[0002] In the tobacco processing industry, the hemp fiber removal machine is a key piece of equipment used to remove linear foreign matter such as hemp fibers and chemical fibers from tobacco leaves. In existing technology, hemp fiber removal machines typically employ a fixed side plate structure, with the gap design between the side plate and the hemp fiber roller primarily based on the operational requirements of the cleaning device. Specifically, during the equipment shutdown and cleaning phase, the hemp fiber suction device needs to move along the channel between the side plate and the hemp fiber roller, removing foreign matter entangled on the surface of the hemp fiber roller through negative pressure adsorption. However, this fixed gap design has significant drawbacks: during production, some tobacco leaves fall directly into the downstream conveyor belt through this gap without being adequately processed by the hemp fiber roller, resulting in reduced foreign matter removal efficiency. Simultaneously, the fixed side plate cannot be dynamically adjusted according to the production stage, causing a functional conflict between the equipment's operation and cleaning modes. If the gap is reduced to improve tobacco leaf processing, it obstructs the movement path of the hemp fiber suction device; if a larger gap is maintained to ensure cleaning functionality, it affects the impurity removal efficiency during normal production. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a hemp fiber removal machine and cigarette rolling equipment.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0009] A linear drive unit, which is mounted on the inner wall of the frame;

[0010] A driven plate is mounted on the output end of the linear drive member. The linear drive member drives the driven plate to move toward or away from the hemp fiber roller, thereby adjusting the distance between the driven plate and the hemp fiber roller.

[0011] Furthermore, the hemp fiber roller includes a rotating shaft, on which a roller shaft is mounted.

[0012] Furthermore, the mounting cavity has a first sidewall and a second sidewall, a first baffle is mounted on the first sidewall, the first baffle is used to cover the end of the roller shaft away from the first sidewall; the linear drive is fixedly mounted on the first sidewall.

[0013] Furthermore, a second baffle is fixedly installed on the first sidewall, and an extension plate is fixedly installed on the driven plate. The linear drive member drives the driven plate to make the extension plate abut against the second baffle.

[0014] Furthermore, the mounting cavity has a first sidewall and a second sidewall, and the linear drive is mounted on both the first sidewall and the second sidewall.

[0015] Furthermore, the hemp fiber removal machine also includes a power unit that drives each of the hemp fiber rollers to rotate synchronously.

[0016] Furthermore, a transfer module is provided on the frame, and a suction component is installed on the moving end of the transfer module. The suction component is used to suction and clean the hemp fibers on the hemp fiber roller.

[0020] This application effectively solves the problem of tobacco leaves falling due to a fixed gap in the prior art by setting a linear drive to drive the driven plate to dynamically adjust the gap between it and the hemp fiber roller. In production mode, the driven plate can move to a position close to the hemp fiber roller, significantly reducing the gap to block the passage of tobacco leaves and ensuring that all tobacco leaves are fully processed by the hemp fiber roller, thereby improving the efficiency of foreign matter removal. In cleaning mode, the linear drive moves the driven plate away from the hemp fiber roller to widen the gap, providing sufficient movement space for the suction component and avoiding obstruction of the cleaning path.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," 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 mechanical connection or an electrical connection; 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.

[0040] Please see Figure 9 and Figure 10As shown, in the prior art, first baffles 700 are provided on both sides of the hemp fiber roller 200. In order to enable the transfer module 500 to drive the transfer module 500 to suck and remove the hemp fibers on each hemp fiber roller 200, there is a gap L between the first baffle 700 on one side and the hemp fiber roller 200 for the suction component 600 to move. However, when the tobacco leaves are conveyed to the hemp fiber roller 200 for hemp fiber removal, the tobacco leaves are easy to fall at the gap L position, and therefore are easy to fall onto the conveyor belt below the hemp fiber roller 200, thus affecting the quality of the finished tobacco.

[0041] This application provides a hemp fiber removal machine, which includes a frame 100, a plurality of hemp fiber rollers 200, a linear drive 300, and a driven plate 400. The frame 100 has a mounting cavity, and the hemp fiber rollers 200 are rotatably mounted in the mounting cavity at intervals. The linear drive 300 is mounted on the inner wall of the frame 100, and the driven plate 400 is mounted on the output end of the linear drive 300. The linear drive 300 drives the driven plate 400 to move toward or away from the hemp fiber rollers 200 to adjust the distance between the driven plate 400 and the hemp fiber rollers 200.

[0042] Please see Figure 1 and Figure 5 As shown, the frame 100 has a mounting cavity, and multiple hemp fiber rollers 200 are evenly spaced and rotated inside the hemp fiber roller 200.

[0043] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, in this embodiment, the linear drive 300 drives the driven plate 400 located on one side of the hemp fiber roller 200 to move. The linear drive 300 drives the driven plate 400 to the end face position of the hemp fiber roller 200, thereby reducing the gap L on one side of the hemp fiber roller 200. Therefore, when it is necessary to remove the hemp fibers from the tobacco leaves, the tobacco leaves are less likely to fall from the gap L onto the conveyor belt below (not shown in the figure).

[0044] The hemp fiber roller 200 includes a rotating shaft 210, on which a roller shaft 220 is provided.

[0045] In one embodiment, the hemp fiber roller 200 mainly includes a rotating shaft 210 rotatably connected to the frame 100, and a roller shaft 220 is fixedly mounted on the rotating shaft 210. The roller shaft 220 rotates synchronously with the rotating shaft 210. It can be understood that the length of the rotating shaft 210 in the axial direction should be greater than the length of the roller shaft 220, and the diameter of the roller shaft 220 is greater than the diameter of the rotating shaft 210.

[0046] Understandably, each rotating shaft 210 drives the roller shaft 220 on it to rotate. When the tobacco leaves pass through each roller shaft 220, the hemp fibers will be wrapped around the roller shaft 220, thereby removing the hemp fibers from the tobacco leaves.

[0047] The hemp fiber removal machine also includes a power unit, which drives each of the hemp fiber rollers 200 to rotate synchronously.

[0048] In this embodiment, a corresponding power device is also installed on the frame 100. The power device can simultaneously drive multiple hemp fiber rollers 200 to rotate. The power device can be a motor, sprocket, chain, or other structure. Specifically, a sprocket is installed on each rotating shaft 210, and the sprockets are connected to each other by a chain. A sprocket is also installed on the output shaft of the motor. This sprocket is connected to the multiple sprockets on the rotating shaft 210 by a chain. Thus, the motor can drive each rotating shaft 210 and roller shaft 220 to rotate through the transmission system composed of sprockets and chains.

[0049] Furthermore, in order for the motor to simultaneously drive the rotation of each shaft 210 and roller 220, a reducer can be installed at the end of the motor shaft. The reducer can convert the high speed and low torque of the motor into low speed and high torque, thereby outputting a larger torque. The output shaft of the reducer is equipped with a sprocket, and the sprocket on the reducer is connected to the sprocket on each shaft 210 through a chain, thereby having sufficient force to drive the rotation of each shaft 210 and roller 220.

[0050] For example, the reducer can be a spur gear or helical gear reducer, or a planetary reducer. It can be understood that any reducer that can achieve speed reduction is acceptable. The appropriate reducer type and model can be selected according to the actual working conditions. The specific reducer type and model are not limited here.

[0051] The mounting cavity has a first sidewall and a second sidewall. The linear drive 300 is fixedly mounted on the first sidewall, and a first baffle 700 is mounted on the second sidewall. The first baffle 700 is used to cover the end of the roller 220 away from the first sidewall.

[0052] See Figure 3 , Figure 4 as well as Figure 5As shown, in one embodiment, when a linear drive 300 is provided on one side of the hemp fiber roller 200, when it is necessary to remove hemp fibers from the tobacco leaves, the linear drive 300 is fixedly installed on the inner wall of the frame 100 on the same side as the gap L. A driven plate 400 is installed on the telescopic end of the linear drive 300. A first baffle 700 is provided at the end of the hemp fiber roller 200 away from the linear drive 300. The first baffle 700 is fixedly connected to the inner wall of the frame 100. The distance between the first baffle 700 and the rotating shaft 210 should meet the production needs, that is, the first baffle 700 should cover the end face of the roller shaft 220 of the hemp fiber roller 200 to prevent the tobacco leaves from falling through the gap between them. The distance between them can be adjusted according to the actual situation. It should be noted that if the first baffle 700 at this position is fixedly connected to the frame 100, it cannot be moved.

[0053] A second baffle 800 is also fixedly installed on the first sidewall, and an extension plate 410 is fixedly installed on the driven plate 400. The linear drive 300 drives the driven plate 400 so that the extension plate 410 abuts against the second baffle 800.

[0054] See Figure 6 and Figure 7 As shown, in one embodiment, a second baffle 800 is also provided above the linear drive member 300. That is, the second baffle 800 is located above the linear drive member 300. In the vertical direction, the driven plate 400 is located on the side of the second baffle 800 facing the rotating shaft 210. In order to prevent a gap between the driven plate 400 and the second baffle 800, an extension plate 410 is provided on the top of the driven plate 400. That is, the extension plate 410 moves together with the driven plate 400. When it is necessary to remove hemp fibers through the suction component 600, the linear drive member 300 retracts and drives the driven plate 400 to move towards the second baffle 800, so that the top of the extension plate 410 abuts against the bottom of the second baffle 800, thereby closing the side of the rotating shaft 210 away from the first baffle 700.

[0055] In this embodiment, in order to drive the driven plate 400 to move stably toward or away from the rotating shaft 210, a linear drive component 300 is provided at both ends of the driven plate 400. For example, the linear drive component 300 can be a cylinder, hydraulic cylinder, electric cylinder or other linear drive component. The specific choice can be made according to the actual working conditions. In this embodiment, the linear drive component 300 is selected as a cylinder.

[0056] In another embodiment, the mounting cavity has a first sidewall and a second sidewall, both of which are on which the linear drive 300 is mounted.

[0057] When linear drive units 300 are installed on both inner side walls of the frame 100, that is, when the linear drive units 300 are located at both ends of the hemp fiber roller 200, when the tobacco leaves need to be de-fired, the driven plates 400 are moved closer to each other by the linear drive units 300 at both ends of the hemp fiber roller 200, so that the driven plates 400 are moved to the end face position of the hemp fiber roller 200, thereby reducing the gap L and preventing the tobacco leaves that have not been de-fired from falling. When the hemp fibers on the outer circumference of the hemp fiber roller 200 need to be sucked away, one or both linear drive units 300 are driven by the driven plates 400 to move away from the hemp fiber roller 200, so that at least one end face of the hemp fiber roller 200 forms a gap L with the driven plate 400 to avoid the movement of the suction assembly 600.

[0058] The frame 100 is provided with a transfer module 500, and the movable end of the transfer module 500 is equipped with a suction component 600, which is used to suction and clean the hemp fibers on the hemp fiber roller 200.

[0059] In one embodiment, the transfer module 500 can drive the suction component 600 to move in at least two directions: horizontal and vertical. Furthermore, in order to enable the suction component 600 to move in multiple directions, in this embodiment, the transfer module 500 can drive the suction component 600 to move in three directions: horizontal, vertical, and vertical. For example, the transfer module 500 can be assembled from three linear modules. For example, the linear modules can be linear components such as motor lead screw linear modules, motor synchronous belt linear modules, and cylinders. The specifics are not limited here.

[0060] The suction assembly 600 includes a suction component and a suction tube, the suction tube having a suction port.

[0061] For example, the suction component can be a blower. In order to remove the hemp fibers from the outer circumference of the rotating shaft 210, the suction assembly 600 can generate negative pressure using a blower. A suction pipe is installed at the suction end of the blower to extract the hemp fibers from the outer surface of the rotating shaft 210. The extracted hemp fibers are then transported through the suction pipe to a collection and discharge device. See [reference needed]. Figure 8 As shown, further, an arc-shaped surface 610 can be opened at the suction port at the end of the suction pipe facing the outer peripheral surface of the rotating shaft 210. The shape of the arc-shaped surface 610 is adapted to the outer surface of the rotating shaft 210. As the transfer module 500 drives the suction pipe to move along the axial direction of the rotating shaft 210, the hemp fibers on the outer surface of the rotating shaft 210 can be combed down, and the combed hemp fibers are sucked up and collected through the suction pipe.

[0062] It is understandable that the arc surface 610 can also be other shapes, that is, the shape of the arc surface 610 changes with the shape of the outer circumference of the roller 220.

[0063] This application also provides a cigarette rolling device, which includes the hemp fiber removal machine described in any of the above embodiments.
