The negative pressure conveying feeding system unit as claimed in claim 3, wherein: one ends of the first raw material conveying pipes (19) far away from the raw material distribution station (6) are respectively and fixedly connected with a feeding hole of the first negative pressure vacuum air pipe (17).
8. A control method of a feeding system unit for negative pressure conveying is characterized in that: the method specifically comprises the following steps:
s1, when the daily system runs, the control system monitors all forming machines (7) needing to be conveyed of the feeding system according to feedback of a material loading level switch arranged on the second vacuum hopper (18), the corresponding forming machines (7) are conveyed according to the sequence of reaction of the material level switch, when one forming machine (7) is empty, the switch transmits signals to the control cabinet (5), the main fan (2) starts the pressure release valve (15) to close and the material cutting valve (8) is opened, and the insides of the second negative pressure vacuum air pipe (22), the first negative pressure vacuum air pipe (17), the main negative pressure vacuum air pipe (20) and the third negative pressure vacuum air pipe (23) reach negative pressure through the action of the vacuum pump.
S2, meanwhile, a first raw material conveying pipe (19) corresponding to the vacant forming machine table (7) is opened by the vacant raw material distribution station (6) of the control cabinet (5), the raw materials stored in the storage bucket (10) are conveyed into the dryer (1) through the first raw material conveying pipe (11) under the action of negative pressure by the fourth negative pressure vacuum air pipe (24) to be dried, then the raw materials are conveyed into the raw material distribution station (6) through the material cutting valve (8) under the action of the second raw material conveying pipe (21), the raw materials are conveyed through the first raw material conveying pipe (19) matched with the opened second vacuum hopper (18), and finally the materials are conveyed into the inside of the forming machine table (7) to be processed.
S3, after the raw materials are processed, smoke generated in the forming machine table (7) enters the dust collector (4) to be filtered, and then the filtered gas is discharged under the action of the main fan (2).
