Abstract
The invention discloses an automatic rotating speed control system for a crushing cylinder. The automatic rotating speed control system comprises the crushing cylinder, a temperature control meter, a crushing motor ampere meter, a crushing motor frequency converter, a conveying belt and a PLC (programmable logic controller) control system, wherein the crushing cylinder is respectively connected with the temperature control meter, the crushing motor ampere meter, the crushing motor frequency converter and the conveying belt, and the PLC control system is respectively connected with the crushing motor frequency converter, the temperature control meter, the crushing motor ampere meter and the conveying belt. The automatic rotating speed control system can sufficiently control the rotating speed of the crushing cylinder, prevent the equipment from being damaged, and enhance production efficiency, and moreover, the automation degree of the automatic rotating speed control system is relatively high.
Description
Technical field
The present invention relates to a kind of broken cylinder speed automatic control system.
Background technology
For the processing of the white garbages such as waste and old food bag, agricultural film, shopping bag for supermarket, the technology of the burning and burying that mostly adopted in the past, this kind processing not only affects environment but also affect limited earth resource.From energy-conserving and environment-protective, the Ecological Concept that turns waste into wealth is set out, and we adopt fragmentation, granule again extruding pelletization or broken forced feed one reclaiming technique mostly to this treatment of wastes produced at present.
Tradition is in broken forced feed one reclaiming of the film technique, broken, feeding is constant speed, this production capacity that reclaims the arts demand screw barrel is greater than broken, forced feed ability, this just causes the production capacity of screw barrel unstable, and the material melt pressure is low, and this just causes the unstable of rear road water ring, tie rod production, causes finished product appearance and size to differ, the defectives such as finished product compactness degree is inadequate, and pore is many.If the control of main frame production capacity is unreasonable with broken cylinder crushing, cause easily material holdup time in broken cylinder long, the heat that produces owing to high-speed friction makes fixed constantly rising of material temperature make the material thawing be bonded to bulk materials, cause material to enter screw barrel and cause the load of broken cylinder to continue to increase, broken motor surpasses the rated current cleaning bulk materials that can only stop, seriously may cause damage of equipment.
Summary of the invention
A technical problem to be solved by this invention is: a kind of broken cylinder speed automatic control system of enhancing productivity is provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of broken cylinder speed automatic control system, comprise: broken cylinder, temp controlled meter, broken galvanometer motor, broken motor frequency conversion device, conveyer belt and PLC control system, described broken cylinder is connected with temp controlled meter, broken galvanometer motor, broken motor frequency conversion device and conveyer belt respectively, and described PLC control system is connected with broken motor frequency conversion device, temp controlled meter, broken galvanometer motor and conveyer belt respectively.
Beneficial effect of the present invention: the broken cylinder speed automatic control system among the present invention can fully be controlled the rotating speed of broken cylinder, and automaticity is higher, has avoided device damage, has improved production efficiency.
Description of drawings
Fig. 1 is the block diagram of broken cylinder speed automatic control system among the present invention.
Among Fig. 1: 1, broken cylinder, 2, temp controlled meter, 3, broken galvanometer motor, 4, broken motor frequency conversion device, 5, conveyer belt, 6, the PLC control system.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, is not intended to limit the present invention.
See also Fig. 1, a kind of broken cylinder speed automatic control system, comprise: broken cylinder 1, temp controlled meter 2, broken galvanometer motor 3, broken motor frequency conversion device 4, conveyer belt 5 and PLC control system 6, described broken cylinder 1 is connected with temp controlled meter 2, broken galvanometer motor 3, broken motor frequency conversion device 4 and conveyer belt 5 respectively, and described PLC control system 6 is connected with broken motor frequency conversion device 4, temp controlled meter 2, broken galvanometer motor 3 and conveyer belt 5 respectively.
The operation principle of described broken cylinder speed automatic control system is: at first broken galvanometer motor 3 is set an electric current safety value, simultaneously temp controlled meter 2 is also set a temperature safety value, then start broken cylinder 1, conveyer belt 5 begins to feed intake to broken cylinder 1, broken cylinder 1 is started working, because conveyer belt 5 continues to feed intake, 1 load of broken cylinder increases, broken cylinder 1 Current rise, start simultaneously extruder, the material of half plasticizing is constantly delivered to extruder, after the production capacity of inventory greater than extruder, broken cylinder electric current surpasses the electric current safety value, after one section time-delay, electric current is still kept above the electric current safety value, at this moment PLC control system 6 work, send a signal to broken motor frequency conversion device 4, by 4 pairs of broken cylinder motor reductions of speed of broken motor frequency conversion device, close simultaneously conveyer belt 5, when electric current returns to rated value, conveyer belt 5 works on, and broken cylinder motor accelerates to setting value simultaneously, because broken cylinder 1 continuous firing, material temperature rise in the broken cylinder 1 surpasses the temperature safety value, after one section time-delay, temperature is still kept overtemperature degree safety value, at this moment PLC control system 6 work, send a signal to broken motor frequency conversion device 4, by 4 pairs of broken cylinder motor reductions of speed of broken motor frequency conversion device, after temperature was recovered normally, broken cylinder motor accelerated to setting value.
Broken cylinder speed automatic control system among the present invention can fully be controlled the rotating speed of broken cylinder, and automaticity is higher, has avoided device damage, has improved production efficiency.
It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment the present invention is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
