Description

Technical Field

[0001] This invention relates to the technical field of cigarette production in tobacco factories, specifically to a pipeline wind speed controller that is easy to install and connect. Background Technology

[0002] The tobacco conveying duct is a component of cigarette manufacturing equipment, responsible for transporting tobacco. It mainly consists of the conveying duct and the blower. The original airflow control was an open-loop system, unable to continuously control the blower speed, resulting in unstable airflow and consequently unstable pressure within the duct. When the airflow is high, the pressure decreases, damaging the tobacco, causing it to break down, and drawing away moisture, severely impacting product quality. Conversely, when the airflow is low, the pressure increases, causing the tobacco to clump together, blocking the duct, leading to downtime and reduced production efficiency. Therefore, cigarette factories need to use duct airflow controllers during production, for example:

[0003] The tobacco shred conveying duct speed control device disclosed in CN2917313U controls the fan speed to ensure normal pressure in the tobacco shred conveying duct. It has the characteristics of reasonable structure, improved production efficiency, guaranteed product quality, energy saving and high efficiency.

[0004] For example, the pipeline wind speed control device with an online closed-loop measurement and control PLD adjustment system disclosed in CN202045087U has a simple structure and significant effect in use. It achieves flexible wind speed control by changing the pipeline damper through PLC. Using PLD adjustment can significantly improve the control accuracy of wind speed and realize real-time control.

[0005] The wind speed control devices disclosed in the two sets of publicly available documents control the size of the fan and the damper via a PLC during use. However, a problem arises during use: after prolonged use, dust accumulates inside the duct wind speed controller, requiring disassembly of the duct or the filter screen installed inside the controller. This necessitates separating the duct wind speed controller from the duct. When reconnecting the controller to the duct, precise positioning is required for installation, which can easily lead to misalignment, hindering the installation process.

[0006] Therefore, we propose a pipeline wind speed controller that is easy to install and connect to, in order to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a duct wind speed controller that is easy to install and connect, in order to solve the problem mentioned in the background art that after a long period of use, duct wind speed controllers on the market will accumulate dust inside, requiring the disassembly of the duct or the filter screen installed inside the duct wind speed controller. At this time, it may be necessary to separate the duct wind speed controller from the duct. When reconnecting the duct wind speed controller to the duct, positioning is required for installation. At this time, it is very easy for misalignment to occur during the connection, which is not conducive to the installation process.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a duct wind speed controller that is easy to install and connect, comprising a duct wind speed control tube body, wherein a set of connecting pipes is installed at both the left and right ends of the duct wind speed control tube body, and ventilation openings for facilitating wind flow are provided between the duct wind speed control tube body and the connecting pipes.

[0009] Also includes:

[0010] The surface of the main body of the duct wind speed control tube is equipped with a control component of a PLC control module. The output end of the control component can control a drive source fixed inside the main body of the duct wind speed control tube. The output end of the drive source is connected to an exhaust fan.

[0011] The connecting pipe has a set of drive motors fixed on its outer side. The output end of the drive motor is connected to a rotating rod, and a set of drive gears is keyed to the outer side of the middle of the rotating rod.

[0012] The outer side of the drive gear meshes with the outer side of the mating gear ring. The mating gear ring rotates inside the connecting pipe to achieve the docking and sealing of the pipe. A set of rotating square grooves is opened on one side surface of the mating gear ring. The inside of the rotating square grooves fits with the mating piece. The outer side of the mating piece fits with the outer side of the elastic airbag. The elastic airbag is connected to the expansion airbag on the inner wall of one end of the connecting pipe.

[0013] As a preferred technical solution of this application, the mating piece includes a movable piece, and a set of squares is fixed at the rear side of the movable piece, and a set of fitting pieces is fixed at the top of the movable piece. A protrusion is installed on the front surface of the movable piece. Through the design of the mating piece, when the drive gear drives the mating gear ring to rotate, the mating gear ring drives the mating piece to slide inside the inclined groove by rotating the square groove, thereby ensuring that the mating piece squeezes the outer side of the elastic airbag.

[0014] As a preferred technical solution of this application, the outer side of the block is attached to the inner wall of the rotating square groove, the outer side of the protrusion is attached to the inclined groove opened in the inner wall of the fixed block, and the attachment piece fixed to the top of the movable piece is arc-shaped. The arc-shaped top of the attachment piece can facilitate the squeezing of the inner side of the elastic airbag, thereby preventing damage to the elastic airbag.

[0015] As a preferred technical solution of this application, the outer side of the fixing block is fixed to the inner wall of the connecting pipe, and the mating piece forms a sliding structure between the inner wall of the rotating square groove and the inclined groove. The other six sets of mating pieces move in the same direction. Through the synchronous movement of the six sets of mating pieces, the arc-shaped fitting piece on one side of the mating piece can squeeze the outer side of the elastic airbag to ensure the gas delivery.

[0016] As a preferred technical solution of this application, both the elastic airbag and the inflatable airbag are made of elastic rubber, and the elasticity of the elastic airbag is greater than that of the inflatable airbag. In addition, the inner side of the inflatable airbag is in contact with the outer side of the pipe, and a set of annular sealing gaskets are adhered to the inner side of the inflatable airbag. By setting the sealing gaskets, gas flow between the pipe and the connecting pipe is prevented.

[0017] As a preferred technical solution of this application, the drive gears are arranged in three sets at equal angles with respect to the center position of the coupling tube, and the inclined grooves are arranged in six sets with respect to the center position of the fixed block. By setting multiple sets of drive gears, the mating gear ring can be rotated, and the mating piece can be stably slid inside the inclined groove.

[0018] As a preferred technical solution of this application, the end of the rotating rod is fixed to one side of the threaded rod, and the other end of the threaded rod is threadedly connected to the inside of the connecting sleeve. The end of the connecting sleeve away from the threaded rod is rotatably connected to the bottom of the receiving rod. An extension sleeve is slidably provided inside the top of the receiving rod, and a drive roller is fixedly connected to the outer side of the extension sleeve by bolts. By adjusting the setting of the limiting block and the extension sleeve, the height of the extension sleeve on the outside of the receiving rod can be easily adjusted, which facilitates sliding.

[0019] As a preferred technical solution of this application, the bottom position of the receiving rod is rotatably connected to the outside of the rotating shaft, and the outer sides of the three sets of rotating shafts are slidably arranged inside the outside of the connecting pipe. In addition, the frictional force of the sliding of the rotating shaft is greater than the frictional force of the rotating receiving rod. When the size of the pipe is too small, the receiving rod rotates first. After rotation, the outer side of the driving roller is attached to the outer wall of the pipe, and at this time, gas is continuously delivered to the expansion bladder to ensure the connection sealing effect.

[0020] As a preferred technical solution of this application, an adjustment limiting block is installed on one side of the top of the receiving rod, and the adjustment limiting block is connected to the inside of the receiving rod by a spring. A hole is opened on the outer side of the extension sleeve to engage with the adjustment limiting block. In addition, a drive motor is provided at the end of the drive roller, which can conveniently drive the roller to roll and realize the movement of the main body of the pipeline wind speed control pipe and the connecting pipe on the outside of the pipeline.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This easy-to-install and docking pipeline wind speed controller is equipped with a rotating shaft. By starting the drive motor, the drive motor drives the rotating rod and the threaded rod to rotate, causing the connecting sleeve to move the receiving rod towards the outer wall of the pipeline. At this time, the gas inside the elastic airbag will not be compressed. When the outer side of the drive roller is in contact with the outer wall of the roller tube, the purpose of positioning and docking can be achieved. The specific details are as follows:

[0022] 1. A rotating shaft is provided. During the docking installation, the drive motor is started, which drives the rotating rod and the threaded rod to rotate. This causes the connecting sleeve to move the receiving rod towards the outer wall of the pipe. At this time, the gas inside the elastic airbag will not be compressed. When the outer side of the drive roller is in contact with the outer wall of the roller tube, the purpose of positioning and docking can be achieved.

[0023] Furthermore, a drive roller is provided. Through the arrangement between the receiving rod and the extension sleeve, the position of the drive roller can be extended and retracted to accommodate different pipes. In addition, after the outer side of the drive roller is attached to the outer side of the pipe, the drive roller can be driven by starting the drive motor to make the drive roller rotate the pipe wind speed control pipe body and the connecting pipe.

[0024] 2. A drive motor is installed, which drives the drive gear to rotate through the output end of the drive motor. This allows the mating gear ring to rotate inside the connecting pipe. In addition, the mating gear ring meshed with the outer side of the mating gear ring drives the rotating square groove to rotate. At this time, the mating piece will move inside the inclined groove through the rotation of the rotating square groove to compress the gas inside the elastic airbag. This can seal the gap between the pipe and the connecting pipe. When reconnecting the pipe wind speed controller to the pipe, positioning treatment is required for installation. At this time, it is very easy for the misalignment problem to occur during the connection.

[0025] Six sets of mating plates are further provided. A block is set on one side of each set of mating plates. The outer side of the block fits into the inside of the rotating square groove. The protrusion fixed on the other side of the mating plate fits into the protrusion opened inside the fixed block. This ensures that the six sets of mating plates move synchronously. The elastic airbag is squeezed by the top of the mating plate to ensure the gas delivery and processing.

[0026] Furthermore, an elastic airbag is incorporated, which is more elastic than the inflatable airbag. A sealing gasket is installed on the inner side of the inflatable airbag to prevent air leakage. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-10 The present invention provides the following technical solution:

[0040] Example 1: To address the issue of misalignment during the re-connection of the duct wind speed controller to the ductwork, which requires precise positioning and hinders installation, please refer to the attached document. Figure 1 - Appendix Figure 4 Appendix Figure 9 and attached Figure 10The end of the rotating rod 8 is fixed to one side of the threaded rod 17, and the other end of the threaded rod 17 is threadedly connected to the inside of the connecting sleeve 18. The end of the connecting sleeve 18 away from the threaded rod 17 is rotatably connected to the bottom of the receiving rod 19. An extension sleeve 21 is slidably disposed inside the top of the receiving rod 19, and a drive roller 22 is fixedly connected to the outer side of the extension sleeve 21 by bolts. The bottom of the receiving rod 19 is rotatably connected to the outer side of the rotating shaft 20, and the outer sides of the three sets of rotating shafts 20 are slidably disposed inside the outer side of the connecting tube 2. In addition, the frictional force of the sliding of the rotating shaft 20 is greater than the frictional force of the rotation of the receiving rod 19. An adjusting limit block 1901 is installed on one side of the top of the receiving rod 19, and the adjusting limit block 1901 is connected to the inside of the receiving rod 19 by a spring. A hole is opened on the outer side of the extension sleeve 21 to engage with the adjusting limit block 1901. A drive motor is disposed at the end of the drive roller 22. When connecting the pipe to the connecting pipe 2 and the vent 3, the drive motor 7 is activated, causing its output to rotate the rotating rod 8. This causes the threaded rod 17, which is keyed to the end of the rotating rod 8, to rotate as well. The threaded connecting sleeve 18 on the outside of the threaded rod 17 then adjusts the angle of the receiving rod 19, allowing the receiving rod 19 to move the drive roller 22 against the outside of the pipe. Before this, pressing the adjusting limit block 1901 moves it within the receiving rod 19 via a spring, adjusting the position of the extension sleeve 21. This allows adjustment of the drive roller 22's position. Once the bottom of the drive roller 22 is against the outside of the pipe, activating the drive motor on one side of the drive roller 22 causes it to move the pipe wind speed control pipe body 1 and the connecting pipe 2 in the opposite direction, facilitating the connection of the other end of the connecting pipe 2. This setup prevents misalignment during connection.

[0041] Example 2: After connecting the pipe and the connecting pipe 2, to ensure a good seal, please refer to the attached document. Figure 4 - Appendix Figure 8The system includes a duct wind speed control pipe body 1, with a set of connecting pipes 2 installed at both ends of the duct wind speed control pipe body 1. Ventilation openings 3 are provided between the duct wind speed control pipe body 1 and the connecting pipes 2 to facilitate airflow. It also includes a control component 4 on the surface of the duct wind speed control pipe body 1, which drives a gear 9 and a mating plate 12 via a control module extension sleeve 21. The output end of the control component 4 can control a drive source 5 fixed inside the duct wind speed control pipe body 1. An exhaust fan 6 is keyed to the output end of the drive source 5. The connecting pipe 2 has a set of fixed... A set of drive motors 7 are provided, with a rotating rod 8 connected to the output end of each motor. A set of drive gears 9 are keyed to the outer side of the rotating rod 8. The outer side of the drive gears 9 is meshed with the outer side of a mating gear ring 10. The mating gear ring 10 rotates inside the connecting pipe 2 to achieve the docking and sealing of the pipe. A set of rotating square grooves 11 are formed on one side surface of the mating gear ring 10. The interior of the rotating square grooves 11 fits against a mating piece 12. The outer side of the mating piece 12 fits against the outer side of an elastic airbag 15. The elastic airbag 15 is connected to an inflatable airbag 16 on the inner wall of one end of the connecting pipe 2. The mating piece 12 includes a movable piece 1201. A set of blocks 1202 are fixed to the rear side of the movable piece 1201, and a set of fitting pieces 1203 are fixed to the top of the movable piece 1201. A protrusion 1204 is installed on the front surface of the movable piece 1201. The outer side of block 1202 is attached to the inner wall of the rotating square groove 11, and the outer side of protrusion 1204 is attached to the inclined groove 14 opened in the inner wall of fixed block 13. In addition, the fitting piece 1203 fixed to the top of moving piece 1201 is arc-shaped. The outer side of fixed block 13 is fixed to the inner wall of connecting pipe 2. The mating piece 12 forms a sliding structure between the inner wall of rotating square groove 11 and inclined groove 14. The moving direction of the other six sets of mating pieces 12 is the same. After docking is completed, the drive motor 7 is started and rotated in the opposite direction, which causes the rotating rod 8 to drive the drive gear 9 to rotate. At this time, the drive gear 9 will drive the meshing gear ring 10 to rotate. Since a rotating square groove 11 is opened on one side of the meshing gear ring 10, the square block 1202 attached inside the rotating square groove 11 drives the moving piece 1201 to move. In addition, the protrusion 1204 fixed on one side of the moving piece 1201 will slide inside the inclined groove 14 through the fixing block 13, so that the fitting piece 1203 fixed on the top of the moving piece 1201 will squeeze the bottom of the elastic airbag 15, so that the gas inside the elastic airbag 15 is delivered to the inside of the inflatable airbag 16, thereby sealing the gap between the pipe and the connecting pipe 2 and preventing air leakage.

[0042] Example 3: To ensure stable gas delivery inside the elastic airbag 15, please refer to the attached document. Figure 4 Appendix Figure 5 Appendix Figure 7 and attached Figure 8 To ensure that both the elastic airbag 15 and the inflatable airbag 16 are made of elastic rubber, and that the elasticity of the elastic airbag 15 is greater than that of the inflatable airbag 16, the inner side of the inflatable airbag 16 is in contact with the outer side of the pipe, and a set of annular sealing gaskets are adhered to the inner side of the inflatable airbag 16. The drive gear 9 has three sets of gears at equal angles to the center of the connecting pipe 2, and the inclined groove 14 has six sets of gears at the center of the fixing block 13. When the square groove 11 is rotated, the six sets of mating plates 12 will move synchronously, causing the mating plates 1203 inside the mating plates 12 to compress the inner side of the elastic airbag 15. Simultaneously, the sealing gaskets inside the inflatable airbag 16 further fill the gap between the pipe and the connecting pipe 2. The drive source 5 is driven by the control component 4, which in turn drives the exhaust fan 6 to operate, facilitating the removal of stems and twigs during the tobacco sorting process.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
