Abstract
The utility model discloses a pelletizer with the cutting speed of a dividing and cutting machine being controlled through a PLC (Programmable Logic Controller). The pelletizer comprises a base body (1), wherein a charging barrel (4) is arranged on the base body (1); a screw rod (3) is arranged in the charging barrel (4); a feeding hole (2) is formed in one end of the charging barrel (4), and a machine head (7) is arranged at the other end of the charging barrel (4); the lower side of the machine head (7) corresponds to one end of a cooling device (8); a dividing and cutting machine (11) is arranged at the other end of the cooling device (8). The pelletizer is characterized in that a pressure gauge (5) is arranged on the charging barrel (4) at the front end of the machine head (7); the pressure gauge (5) is connected with a PLC control device (6) through a circuit; the PLC control device (6) is connected with a motor of the dividing and cutting machine (11) through a circuit. Cut material particles are uniform by controlling the rotating speed of the dividing and cutting machine through the PLC control device according to the pressure of materials in the charging barrel. Moreover, the pelletizer is convenient to use.
Description
Technical field:
The utility model relates to comminutor technical field, is a kind of comminutor of being controlled cutting machine cutting speed by PLC specifically.
Technical background:
At present, granulator granulation process is: the plastics that will carry out all size of granulation are added in barrel and are heated by charge door, and stir fusion plastification by bolt rotary, form after certain pressure at barrel front end, extrude rectangular from cross-head by screw rod, be cut into grain by cutting machine again, complete granulation; But due to the own Density inhomogeneity charge door fed in raw material, feed in raw material and expect between interval different, make the fused materials pressure in barrel inhomogeneous, therefore just different from the speed of head discharging, the rectangular density of extruded stock is different with thickness specification, therefore the plastics that cutting machine cuts out are just inhomogeneous, have influence on use.
Utility model content:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of comminutor of being controlled cutting machine cutting speed by PLC is provided; Mainly solve existing comminutor and cannot solve the inhomogeneous problem of granulation because of fed in raw material former thereby generation.
The technical solution of the utility model is: a kind of comminutor of being controlled cutting machine cutting speed by PLC; it comprises support body; on support body, establish barrel; in barrel, establish screw rod; charge door is established in one end of barrel; the other end is established head; one end of the corresponding cooling device in head below; the other end of cooling device is established cutting machine; in cooling device, establish carry-over pinch rolls, its special character is, on the barrel of described head front end, establishes Pressure gauge; Pressure gauge is connected with PLC control device by circuit, and PLC control device is connected with the motor of cutting machine by circuit.
Described in the utility model: compared with the prior art a kind of comminutor by PLC control cutting machine cutting speed has following good effect: adopt PLC control device to control the velocity of rotation of cutting machine according to the pressure size of material in barrel; make the material grain that cuts out more even, and easy to use.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
For Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model in detail; Illustrated embodiment is only for explaining the utility model, not for limiting scope of the present utility model.
Embodiment 1, referring to Fig. 1, need to select suitable support body 1 according to design, at the interior installation screw rod 3 of barrel 4, barrel 4 is arranged on support body 1, charge door 2 is installed in one end at barrel 4, position is corresponding with the screw rod 3 in barrel 4, the other end at barrel 4 is installed head 7, cooling device 8 is installed below head 7, and head 7 is corresponding with one end of cooling device 8, at the other end of cooling device 8, cutting machine 11 is installed, at the interior installation carry-over pinch rolls 10 of cooling device 8, guide to cutting machine 11 places by carry-over pinch rolls 10 by rectangular the material of extruding 9 and cut granulation; Setting pressure table 5 on the barrel 4 of head 7 front ends, Pressure gauge 5 is connected with PLC control device 6 by circuit, and PLC control device 6 is connected with the motor of cutting machine 11 by circuit.
A kind of comminutor of being controlled cutting machine cutting speed by PLC described in the utility model, its operation principle is: material is in barrel after plastifying fusion, head by extruder is extruded, cooling through apparatus for supercooling, by carry-over pinch rolls, granulation is cut to by the rectangular material cutting machine place that guides to; Pressure gauge reading outside head is the pressure of material in barrel, the PLC control device initialize program being connected with Pressure gauge, according to the velocity of rotation of the size control cutting machine of pressure, in the time that pressure is large, the cutting speed of PLC control device cutting machine is accelerated, and when pressure hour, the cutting speed of PLC control device cutting machine is slack-off, thereby make the material grain that cuts out more even, easy to use.
