Example

[0025] like Figure 1-5 This embodiment proposes a wind-powered feeding system, including a wire suction duct, one end of which is connected to the feeder in the silk-making workshop, and the other end is connected to the feeding bin of the winding machine. The feeder is provided with a material sensor 41 for receiving a material request signal and a material stop signal. The feeding bin is provided with a high-level photoelectric detector 42 and a low-level photoelectric detector 43. When the low-level photoelectric detector detects that there is no material, it sends a material request signal. After receiving the material request signal, the material sensor 41 of the feeder starts feeding. Furthermore, the feeding bin is provided with a damper, and the damper is provided with a valve connected to an opening and closing controller 46. The opening and closing controller 46 is respectively connected to the signals of the high-level photoelectric detector 42 and the low-level photoelectric detector 43. When the low-level photoelectric detector detects that there is no material, it sends a material request signal, and the opening and closing controller 46 controls the valve to open the damper; when the high-level photoelectric detector detects that the material is about to be full, it sends a material stop signal, and the opening and closing controller 46 controls the valve to close the damper. A roller is provided at the bottom of the feeder, and a roller needle is provided on the roller to rotate and loosen the tobacco.

[0026] Among them, Figure 1As shown, the vertical pipe 1 of the wire suction duct near one end of the feeder is divided into an upper part and a lower part, and the upper and lower parts of the pipe are assembled and connected by a connecting plate 2. Figure 2 As shown, the connecting plate 2 includes a circular hollow structure 21, and the diameter of the circular hollow structure 21 is less than or equal to the inner diameter of the vertical pipeline 1. The connecting plate 2 is provided with a plug-in slot 23 and a plug-in plate 22. Figure 3 As shown, the plug board 22 can be inserted into the plug slot 23. After the plug board 22 is inserted into the plug slot 23, the hollow structure 21 of the connecting plate 2 can be closed. The pipeline located above the connecting plate 2 has a vent 24 on the side wall near the connecting plate 2. The vent 24 is opened and closed by a baffle 25. Furthermore, the outer contour of the connecting plate 2 can be set to a rectangular shape, and the plug slot 23 is set in the middle of the connecting plate 2. Figure 1 As shown, vertical slide rails 251 are provided on both sides of the vent 24. Figure 4 As shown, the baffle 25 is in an arc shape, and the baffle 25 is connected to the vertical slide rail 251 and can move up and down along the vertical slide rail 251.

[0027] Preferably, in order to realize automatic control of the movement of the plug board 22 and the baffle 25, the plug board 22 is connected to the first cylinder, and the movement of the first cylinder is controlled by the first solenoid valve 44, and the baffle 25 is connected to the second cylinder, and the movement of the second cylinder is controlled by the second solenoid valve 45. Preferably, the first solenoid valve 44 and the second solenoid valve 45 are 2-position 5-way solenoid valves respectively.

[0028] Preferably, Figure 5 As shown, it also includes a PLC controller 3, which is connected to the material sensor 41, the high material level photoelectric detector 42, the low material level photoelectric detector 43, the first solenoid valve 44, the second solenoid valve 45 and the opening and closing controller 46 for controlling the operation of the pneumatic conveying feeder system.

[0029] Preferably, the high material level photoelectric detector 42 and the low material level photoelectric detector 43 are respectively connected to the material sensor 41 signal. It is used to transmit the material request signal and the material stop signal. Further, the high material level photoelectric detector 42 and the low material level photoelectric detector 43 are respectively connected to the first electromagnetic valve 44 signal. When the material request signal is transmitted to the material sensor 41, the material request signal is also transmitted to the first electromagnetic valve 44, which is used to control the movement of the first cylinder, open the plug board 22, and start feeding. When the material stop signal is transmitted to the material sensor 41, the material stop signal is also transmitted to the first electromagnetic valve 44, which is used to control the movement of the first cylinder, close the plug board 22, and stop feeding.

[0030] Furthermore, the first solenoid valve 44 is connected to the second solenoid valve 45 by signal. When the first solenoid valve 44 receives the material request signal transmitted by the material sensor 41, it controls the first cylinder to open the plug board 22, transmits the material request signal to the second solenoid valve 45, and the second solenoid valve 45 controls the baffle 25 to move downward, closes the vent 24, and starts feeding. When the first solenoid valve 44 receives the material stop signal transmitted by the material sensor 41, it controls the first cylinder to close the plug board 22, and transmits the material stop signal to the second solenoid valve 45, controls the second cylinder to open the baffle 25, and at this time, the vent 24 is opened. Furthermore, the opening and closing controller 46 is set to close the damper after a delay of 5 to 10 seconds. In this way, the tobacco material that has not yet been sucked into the feeding bin can be sucked away, avoiding the problem of material crushing and blocking the tobacco suction air duct.

[0031] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
