As shown in fig. 1, the vacuum suction hopper 2 is provided with an air shutoff valve 21.
In this embodiment, when the air stop valve 21 is opened, the vacuum assembly 3 can be communicated with the vacuum suction hopper 2, so that negative pressure can be formed in the vacuum suction hopper 2 to suck the raw material in the raw material pipe 11 into the vacuum suction hopper 2.
As shown in connection with fig. 1, the negative pressure device 4 is a Roots blower.
It will be appreciated that the negative pressure device 4 need only be capable of drawing air out of the vacuum tube assembly 3, and is therefore not limited to the form of a Roots blower, and in other embodiments the negative pressure device 4 is a negative pressure power source such as a high pressure centrifugal blower capable of drawing air out of the vacuum tube assembly 3.
