According to the present invention, the vacuum thermal insulation chamber is arranged, and the vacuum thermal insulation chamber and the thermal insulation housing are co-used to carry out thermal insulation on the material heating cylinder, such that the thermal insulation effect is further enhanced, and the heat loss is substantially avoided so as to save the energy source.
Description
Technical field
The present invention relates to high molecule plastic production technical field, particularly relate to a kind of high molecule plastic Melt Flow Rate Measurer.
Background technology
In the production run of high molecule plastic, usually need to use the melt flowability of Melt Flow Rate Measurer to high molecule plastic to weigh, after being analyzed by the flow rate of the high molecule plastic solution to the different trade mark, the high molecule plastic adapting to processing technology requirement can be better selected to carry out post-production, improve reliability and the quality of polymer plastic material products, but the heat insulation effect of existing solution flow rate instrument housing is undesirable, the loss of heat can be caused, waste energy; And the cutter of existing Melt Flow Rate Measurer carries out blank by Electric Machine Control by rotation, this blank mode can make turning axle place be subject to larger torsion, substantially reduces the serviceable life of cutter; And inside has bubble after plastics materials melting in heating cylinder, the bubble in melt cannot be discharged, thus affects measurement result.
Summary of the invention
According to above technical matters, the invention provides the high molecule plastic Melt Flow Rate Measurer that a kind of measuring accuracy is high, comprise insulation shell, heating cylinder, knife plate, cutter groove, discharging opening, cutter, mouth mould, piston, connecting rod, counterweight seat, it is characterized in that: also comprise vacuum heat-preserving chamber, vacuum orifice, pneumatic control components, bleed-off passage, the inside of described insulation shell is provided with heating cylinder, cavity between described insulation shell and heating cylinder is vacuum heat-preserving chamber, described insulation shell offers vacuum orifice, the bottom of described heating cylinder is provided with a mouthful mould, the lower end of described insulation shell is provided with knife plate, the inside of described knife plate offers cutter groove, position corresponding with mouth mould on described knife plate offers discharging opening, described cutter is arranged in cutter groove by pneumatic control components, the inside of described heating cylinder is provided with piston, the upper end of described piston is provided with connecting rod, described counterweight seat is spirally connected and is arranged on the upper end of connecting rod, described piston, the center of connecting rod is provided with bleed-off passage.
Described vacuum orifice is communicated with vacuum heat-preserving chamber.
Beneficial effect of the present invention is: the present invention improves on original Melt Flow Rate Measurer, namely between insulation shell and heating cylinder, vacuum heat-preserving chamber is added, can be vacuumized to vacuum heat-preserving chamber by vacuum orifice, jointly heating cylinder is incubated by vacuum heat-preserving chamber and insulation shell, further enhancing heat insulation effect, largely avoided a large amount of losses of heat, thus save the energy; Also by pneumatic control components, cutoff tool transverse reciprocating is moved to cut off melt, long service life, can also block by counterpart mould, avoiding unnecessary melt outflow affects measurement result; Also offer bleed-off passage at the center of piston, connecting rod, the gas in melt can have been extracted out by bleed-off passage, increase measuring accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
According to Fig. 1, the present invention is further described:
As Fig. 1, insulation shell-1, heating cylinder-2, knife plate-3, cutter groove-4, discharging opening-5, cutter-6, mouth mould-7, piston-8, connecting rod-9, counterweight seat-10, vacuum heat-preserving chamber-11, vacuum orifice-12, pneumatic control components-13, bleed-off passage-14.
Embodiment 1
The present invention includes insulation shell 1, heating cylinder 2, knife plate 3, cutter groove 4, discharging opening 5, cutter 6, mouth mould 7, piston 8, connecting rod 9, counterweight seat 10, vacuum heat-preserving chamber 11, vacuum orifice 12, pneumatic control components 13, bleed-off passage 14, first vacuum orifice 12 is arranged on insulation shell 1 during installation, then heating cylinder 2 is arranged on the inside of insulation shell 1, at this moment vacuum heat-preserving chamber 11 is formed between insulation shell 1 and heating cylinder 2, mouth mould 7 is arranged on the bottom of heating cylinder 2, cutter groove 4 is offered again in the inside of knife plate 3, discharging opening 5, then knife plate 3 is arranged on the lower end of insulation shell 1, cutter 6 is arranged in cutter groove 4 by pneumatic control components 13, at piston 8, bleed-off passage 14 is offered at the center of connecting rod 9, again the lower end of piston 8 with connecting rod 9 is connected, counterweight seat 10 is spirally connected and is arranged on the upper end of connecting rod 9, finally piston 8 is arranged on the inside of heating cylinder 2.
Embodiment 2
During use, first in heating cylinder 2, appropriate high molecule plastic particle is added, then piston 8 is arranged in heating cylinder 2, opening power, heating cylinder 2 heats high molecule plastic particle makes its melting, after the gas in melt being extracted out by bleed-off passage 14, counterweight is placed on counterweight seat 10, now start timing, by the pressure of counterweight, piston 8 is moved down, melt is squeezed from mouth mould 7 and flows out, when reaching the schedule time, pneumatic control components 13 controls cutter 6 transverse shifting and is cut off by melt, and the melt cut off is weighed, complete the measuring process of whole melt flow rate.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
