Detailed Implementation

[0017] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0018] As described in the background section, while existing dust removal systems can effectively achieve dust removal, they consume a lot of energy.

[0019] It should be noted that when the tobacco sorting system is working, the screen boxes of the first vibrating screen 500 and the second vibrating screen 600 will vibrate significantly. When the dust removal system is working, the guide pipe will vibrate slightly.

[0020] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4This invention provides a cigarette factory pack receiving dust removal system, including a first collection hood 110, a first guide pipe 120, a dust collector 130, a second guide pipe 140, a plurality of first vibration energy capture mechanisms 150, a plurality of second vibration energy capture mechanisms 160, and an electrical energy storage device 170 (not shown in the figure). The inlet of the first collection hood 110 is adapted to communicate with a first settling tank 300. One end of the first guide pipe 120 is fixedly connected to and communicates with the outlet of the first collection hood 110. The inlet of the dust collector 130 is connected to the other end of the first guide pipe 120. One end of the second guide pipe 140 is adapted to communicate with a second settling tank 400, and the other end is connected to the middle of the first guide pipe 120. At least one first vibration energy capture mechanism 150 is adapted to connect to the screen box of a first vibrating screen 500, for converting the vibration energy of the screen box of the first vibrating screen 500 into electrical energy. At least one first vibration energy harvesting mechanism 150 is adapted to be connected to the screen box of the second vibrating screen 600, for converting the vibration energy of the screen box of the second vibrating screen 600 into electrical energy. At least one second vibration energy harvesting mechanism 160 is adapted to be connected to the outer wall of the first guide pipe 120, for converting the vibration energy of the first guide pipe 120 into electrical energy. At least one second vibration energy harvesting mechanism 160 is adapted to be connected to the outer wall of the second guide pipe 140, for converting the vibration energy of the second guide pipe 140 into electrical energy. An electrical energy storage device 170 is electrically connected to each first vibration energy harvesting mechanism 150 and each second vibration energy harvesting mechanism 160, respectively, for storing electrical energy. Airflow from the first settling tank 300 flows sequentially through the first collecting hood 110 and the first guide pipe 120, and then flows into the dust collector 130. Airflow from the second settling tank 400 flows sequentially through the second guide pipe 140 and the first guide pipe 120, and then flows into the dust collector 130. Dust collector 130 removes dust mixed in the airflow. Multiple first vibration energy capture mechanisms 150 capture the vibration energy of the first vibrating screen 500 and the second vibrating screen 600 when they operate with relatively large vibration amplitudes, converting the vibration energy into electrical energy. Multiple second vibration energy capture mechanisms 160 capture the vibration energy of the first guide pipe 120 and the second guide pipe 140 when they operate with relatively small vibration amplitudes, converting the vibration energy into electrical energy as well. This electrical energy can be utilized by the cigarette factory's package receiving dust collection system, which helps reduce the energy consumption of the cigarette factory's package receiving dust collection system.

[0021] Reference Figure 1 and Figure 2In some embodiments, each first vibration energy harvesting mechanism 150 includes a first follower seat 151, a support beam 152, a flexible fixing block 153, a rigid drive block 154, a housing 155, a plurality of first coils 156, a ratchet 157, and a plurality of first permanent magnets 158. The first follower seat 151 is adapted to be fixedly connected to the outer wall of the screen box of the first vibrating screen 500 / second vibrating screen 600. The support beam 152 is vertically arranged, and its top end is fixedly connected to the first follower seat 151. The flexible fixing block 153 is fixed to one side of the bottom end of the support beam 152. The rigid drive block 154 is fixed to the bottom end of the flexible fixing block 153. The housing 155 is disposed below the support beam 152 and is fixedly connected to the frame 200. The plurality of first coils 156 are evenly mounted on the inner wall of the housing 155 along the circumference of the housing 155. A ratchet 157 is rotatably mounted below the support beam 152, with its central portion rotatably connected to one end of the housing 155 via a pivot shaft. Its sidewalls can contact the bottom end of the rigid drive block 154. Multiple first permanent magnets 158 are evenly mounted on the outer wall of the ratchet 157 along its circumference and rotate with it. When the first vibrating screen 500 / second vibrating screen 600 is operating, it drives the first follower seat 151 to vibrate, causing the bottom end of the support beam 152, the flexible fixing block 153, and the rigid drive block 154 to oscillate at high frequency. The rigid drive block 154 drives the ratchet 157 to rotate unidirectionally, thereby driving the multiple first permanent magnets 158 to rotate. During the rotation of the multiple first permanent magnets 158, the magnetic flux of each first coil 156 mounted on the inner wall of the housing 155 changes, causing each first coil 156 to generate electricity. It should be noted that the support beam 152 is a stainless steel spring sheet. The first follower seat 151, rigid drive block 154, housing 155, and ratchet 157 are made of plastic with a certain degree of hardness, serving as insulation. The flexible fixing block 153 is made of silicone or rubber. The flexible fixing block 153 and the rigid drive block 154 cooperate with each other to adaptively adjust their stiffness. When oscillating forward to drive the ratchet 157 to rotate, it has high stiffness. When oscillating in the reverse direction, it has low stiffness to avoid hindering the rotation of the ratchet 157.

[0022] Reference Figure 1 , Figure 3 and Figure 4In some embodiments, each second vibration energy harvesting mechanism 160 includes a sleeve 161, a plurality of second coils 162, an end cap 163, a rotor 164, a plurality of second permanent magnets 165, a second follower seat 166, and two drive ropes 167. Guide strips 1611 are formed on the inner walls of opposite sides of the sleeve 161. The plurality of second coils 162 are uniformly mounted on the outer wall of the sleeve 161 along the circumference of the sleeve 161. The end cap 163 is fixed to one end of the sleeve 161. The end cap 163 is fixedly connected to the frame 200 by a support rod. The rotor 164 is rotatably mounted inside the sleeve 161. The plurality of second permanent magnets 165 are uniformly mounted on the outer wall of the rotor 164 along the circumference of the rotor 164, and all rotate with the rotor 164. The second follower seat 166 is axially movable at the other end of the sleeve 161. Guide grooves matching the guide strips 1611 are formed on the outer walls of its opposite sides. One end is suitable for fixed connection to the outer wall of the first guide pipe 120 / second guide pipe 140. Two transmission ropes 167 are arranged crosswise, one end fixedly connected to the end cap 163, the other end fixedly connected to the second follower seat 166, and the middle part fixedly connected to the middle of the rotor 164. When the first guide pipe 120 / second guide pipe 140 is working, it drives the second follower seat 166 to move axially along the sleeve 161. The guide strips 1611 on both sides cooperate with the corresponding guide grooves to provide initial torsional force to the second follower seat 166. The moving and rotating second follower seat 166, the stationary end cap 163, and the two transmission ropes 167 cooperate to drive the rotor 164 to rotate, thereby driving the multiple second permanent magnets 165 to rotate. During the rotation of the multiple second permanent magnets 165, the magnetic flux of each second coil 162 mounted on the outer wall of the sleeve 161 changes, causing each second coil 162 to generate electricity. It should be noted that the sleeve 161, end cap 163, rotor 164, and second follower seat 166 are made of plastic with a certain degree of hardness, serving an insulating function. Each transmission rope 167 is a nylon rope.

[0023] In some embodiments, the cigarette factory's package receiving dust removal system further includes a negative pressure generating device, a first exhaust fan, and a second exhaust fan. The negative pressure generating device is connected to the outlet of the dust collector 130 and can generate negative pressure to drive airflow. The first exhaust fan is operably installed at the outlet of the first collection hood 110 and electrically connected to an energy storage device 170, which supplies power to the first exhaust fan to operate it. The second exhaust fan is rotatably installed inside the end of the second guide pipe 140 away from the first guide pipe 120 and electrically connected to the energy storage device 170, which supplies power to the second exhaust fan to operate it. When the operating power of the negative pressure generating device remains constant, the participation of the first and second exhaust fans in dust removal can increase the airflow velocity, thereby improving dust removal efficiency. When the first and second exhaust fans participate in dust removal, the operating power of the negative pressure generating device can be reduced, thereby reducing energy consumption.

[0024] In some embodiments, the cigarette factory's package receiving dust removal system further includes a first pressure sensor, a second pressure sensor, and an air inlet distribution device 180. The first pressure sensor is mounted on a first guide pipe 120 and is used to detect the air pressure inside the first guide pipe 120. The second pressure sensor is mounted on a second guide pipe 140 and is used to detect the air pressure inside the second guide pipe 140. One end of the air inlet distribution device 180 is connected to the first guide pipe 120, and the other end is connected to the dust collector 130. The air inlet distribution device 180 ensures that the dust-laden airflow flows evenly into the dust collector 130.

[0025] Preferably, the dust collector 130 is a bag filter dust collector 130.

[0026] It should be noted that the structure and working principle of the energy storage device 170, the negative pressure generating device, the air intake distribution device 180, the first settling box 300, the second settling box 400, the first vibrating screen 500 and the second vibrating screen 600 are all existing technologies and will not be described in detail here.
