It can continuously stablize to screw conveyor 41 and convey, be carried out continuously plastic processing can；
The conveying for carrying out long range by screw conveyor 41 again, actively gives powder carry power, powder is in spiral transferring
Send in machine 41 will not there is a phenomenon where windrow, build bridge the stable and uniform so that powder carry discharges, and then guarantee modified plastics
Performance.
Embodiment two,
As shown in Fig. 5, a kind of horizontal feed drawing-in device, improves on the basis of example 1, with reality
The cloth of example one is applied the difference is that the hard straight tube 431 that the first discharge nozzle 21 is vertically arranged, the first discharge nozzle 21 and feed pipe
It is connected between mouth 34 by the first hose 22.Pipeline vibrator 23, pipeline are installed on the side of the first discharge nozzle 21 simultaneously
Vibrator 23 can the first discharge nozzle of active vibration 21, prevent powder the first discharge nozzle 21 inside attach, be not necessarily to manual cleaning,
Bridging of powder phenomenon is avoided to occur.
As shown in Fig. 6, the upper end cap of the first hose 22 is under the outside of 21 lower end of the first discharge nozzle, the first hose 22
End cap is in the outside of charging nozzle 34.Fixing hoop 221, fixing hoop 221 are cased with outside the top and bottom of first hose 22
Inside compress the top and bottom for clamping the first hose 22, make itself and corresponding first discharge nozzle, 21 lower end and feed nozzle 34
It is fixed.
Similar to embodiment one, the gone out powder in 21 lower end of the first discharge nozzle can be with the first hose 22 when passing through the first hose 22
It collides, the first hose 22 vibrates, so that elastic force of the powder in the first hose 22 by direction, powder is interior with knot
Block, which is pressurized, to be crushed, and then the mobility of raising powder, and avoiding powder from blocking out in charging nozzle 34 causes in the first discharge nozzle 21
Powder accumulation.The first discharge nozzle 21 is played a supporting role simultaneously, prevent the first hose 22 it is too long bend or rotate to overlap lead
The first hose 22 is caused to block.
The working principle of embodiment two:
First hose 22 is fixed by top and bottom fixing hoop 221, easy for assemble or unload, clear convenient for the first hose 22
Reason, while the vertical fixed position of 22 top and bottom of the first hose can be also freely adjusted, to adjust the stretching of the first hose 22
Tensioning degree sexually revises the powder elastic force reversed by the first hose 22 according to the bonding of powder.
