The distance in portion, can effectively it prevent because the other reasonses such as operational error caused may touch screw rod, so as to damage screw rod
And influence extruder and run well, on the one hand the setting of this shape can prevent sampler from reaching deep down into machine barrel sampling
When, the material under any depth in screw channel can be as requested taken, and sampling process is pacified in the case where not touching screw rod
It is complete effective, simple to operate.This guarantees sampling catheter not to interfere with normal work, will not damage screw rod yet, it is ensured that sampling
Security.
As shown in figure 4, there is one section of branch the sampling catheter upper end, posting speed containing one inside the brasnch conduct passes
The spheroid of sensor 17, the velocity sensor 17 are attached to the surface of the one end of spheroid away from bifurcations, the velocity sensor 17
It is connected with the signal acquisition controller 12, the signal acquisition controller 12 is connected with the micro-machine 13.Work as sampling amount
When reaching definite value, take material to enter in branched pipe, promote bead, bead speed changes, the velocity sensor 17
Information is transmitted to signal acquisition controller 12, signal acquisition controller 12 sends control signal and is communicated to micro-machine 13, now
Motor starts to invert, and drives retractor device to move up, and stopping continues to sample, so as to realize the function of quantitative sampling, and
Sampling activity can be terminated after quantitative sampling, safely and effectively.
The implementation process of the screw extruder automatic material taking：The air chamber 4 of feeding device, junction chamber 5, sampling room 6 are
Removable subassembly, air chamber 4 and sampling room 6 are connected by junction chamber 5, and the lower end of sampling room 6 is fixed together with machine barrel,
It is sampled by the hole 24 on machine barrel to realize that probe tube enters inside machine barrel, temperature and pressure inside sampling mechanism
When not reaching the temperature and pressure in predetermined machine barrel, hole 24 is blocked by the block, when reaching predetermined temperature and pressure, triggering
Mechanism 1 acts on the block, and the block mobile sampler structure is connected with inside machine barrel by the hole 24.When accumulator 11 is
The temperature and pressure of sampling mechanism 10 increases in cylinder after temperature and pressure, and telescoping mechanism 15 drives sampling catheter 16 to start downwards
Mobile, the local temperature and pressure being now in contact with machine barrel are with consistent in machine barrel, so the progress of reaction is not interfered with,
The normal operation of extruder is not interfered with, samples this valuable and meaning.After taken inventory reaches definite value, motor is anti-
Turn, drive telescoping mechanism to move up, stop sampling process.Determined between machine barrel element by locating ring 25 and alignment pin 26
Hyte fills.
