[0030] Embodiment one

[0031] With reference to Figures 1-4 A kind of air-laid edge material system anti-blocking device, including feeding fan 5, slitting edge disc driving device 6 and material tower 3, slitting edge disc driving device 6 is used to drive existing slitting disc feeding. Feeding fan 5 and material tower 3 are connected by feeding pipeline 4, cyclone separator 1 is arranged on the upper portion of material tower 3, and material tower 3 is also provided with pressure sensor 2. Pressure sensor 2 is mainly used to detect the pressure in material tower 3 and feeding pipeline 4, and feeding fan 5 and cyclone separator 1 are air supply and exhaust respectively, to keep the internal pressure relatively stable. Generally, the pressure in the material bin is kept at-1mbar, and feeding fan 5 is operated at power frequency, and the pressure is mainly adjusted by the speed of the variable frequency motor of cyclone separator 1. Feeding fan 5 sends raw materials to material tower 3 and selects raw materials through cyclone separator 1, and excess air is discharged to ensure the normal pressure in the container of material tower 3. When feeding pipeline 4 is unblocked, the air discharged by cyclone separator 1 is constant with the air sent by feeding fan 5. When feeding pipeline 4 is blocked, the air volume in feeding pipeline 4 decreases, and the working frequency of cyclone separator 1 is affected and decreases. The motor of cyclone separator 1 is controlled by frequency converter 7, and frequency converter 7 adopts Siemens MICROMASTER 440 frequency converter.

[0032] As Figure 2 andFigure 3 As shown, KA is used to represent the intermediate relay 8, the frequency converter 7 is provided with No. 18 and No. 20 terminals, the power line 9 is connected to the No. 18 terminal in the frequency converter 7 of the motor of the cyclone separator 1, and the control coil of the intermediate relay 8 is led out from the No. 20 terminal and connected to the intermediate relay 8, and then the alarm lamp in the control room is controlled through a normally open contact KA-1 of the intermediate relay 8, and HL is used to represent the alarm lamp. Figure 4 As shown, KM is used to represent the contactor for controlling the start and stop of the slitting edge disc driving device 6, and the normally closed contact KA-2 of the intermediate relay 8 is connected in series in the start and stop circuit of the slitting edge disc driving device 6, and is used to control the contactor to stop the slitting edge disc driving device 6 in time, that is, to stop the slitting edge disc feeding in time. In actual production operation, through multiple test practices, the parameters of P731 in the frequency converter 7 can be modified to 53.5, and the parameter of P2155 is modified to the motor frequency of the cyclone separator 1 to be set, when the actual motor frequency is lower than the set frequency, the alarm lamp alarms, and the slitting edge disc driving device 6 stops, that is, the slitting edge disc stops feeding. The utility model monitors the working frequency of the cyclone separator 1 through the IO output point of the cyclone separator 1 and a programmable frequency converter 7, to achieve the purpose of monitoring whether the feeding pipeline 4 is blocked. When the feeding pipeline 4 is blocked, the air volume in the feeding pipeline 4 decreases, the working frequency of the cyclone separator 1 decreases, the IO point of the frequency converter 7 acts, outputs a signal to the intermediate relay 8, and controls the alarm lamp HL and the contactor KM through the intermediate relay 8. At this time, the alarm lamp lights up and alarms, and the slitting edge disc driving device 6 stops, that is, the slitting edge disc stops feeding, to achieve the purpose of timely discovery, and at the same time, the purpose of stopping the slitting edge disc feeding is achieved, the effect of timely cleaning and reducing the material in the feeding pipeline 4 is realized, the staff can timely discover, and the normal feeding fan 5 continuously sends air without stopping, thereby dredging and cleaning the material in the feeding pipeline 4, so as to reduce the cleaning time caused by blocking and prevent the occurrence of blocking.

[0033] Example two

[0034] The difference between this example and example one is that:

[0035] The middle part of the feeding pipeline 4 is also coaxially corresponding and provided with an annular sleeve 10, the inside of the annular sleeve 10 is coaxially provided with an annular shell 11, one end of the annular shell 11 is fixedly connected with the annular sleeve 10, and the other end of the annular shell 11 is provided with a gap between the annular sleeve 10 and is connected with the one end of the feeding pipeline 4, the outside of the annular sleeve 10 is uniformly provided with a plurality of air inlet pipes 12, the air inlet pipes 12 are obliquely arranged with the outer wall of the annular sleeve 10, the plurality of air inlet pipes 12 are fixedly connected with the one end of the annular shell 11, and the plurality of air inlet pipes 12 are correspondingly provided with an air inlet mechanism.
