Description
Technical field
This utility model relates to a kind of system, particularly a kind of plasterboard stably feeding automatic control system.
Background technology
In the production process of existing plasterboard; one control refers to start to plasterboard to enter this section of production line of drying machine from charging; and the feed stability of a control is particularly significant; it plays vital effect to the seriality of production and the quality of product; existing control system cannot ensure the stability of feed, often occurs to put bag, stopping accident without material, and when feeding coal cannot meet production requirement; water paste ratio is undergone mutation, and affects the quality of product greatly.
Existing control system uses slide rheostat to carry out frequency and gives, post work rotary knob be adjusted lattice wheel frequency, control discharge quantity, it is impossible to be automatically adjusted.Owing to lattice wheel is not carried out automatically controlling, it is by observing blanking situation by post work, carries out the regulation to lattice wheel frequency; if it is improper to regulate; material leakage phenomenon can occur at reamer, site environment health be had a negative impact, time serious, also can cause shutdown.Pipe reamer uses VFC simultaneously, utilizes Linear Control, it is ensured that the feeding coal of belt conveyer scale feeding in program, and response speed is slow, controls inaccuracy.When in hopper, material is few, the LOAD CELLS output valve under hopper becomes big, and pipe reamer frequency becomes big, and revolution is accelerated, but leading portion is not changed in for feeding coal, causes material few；Belt conveyer scale feeding is few simultaneously, and LOAD CELLS output becomes big, and belt conveyer scale frequency increases, and belt revolution increases, and can reach 100HZ, to belt and motor all with great damage.But owing to doses supply reduces, form poor circulation, ultimately result in thanks to expect, the generation of the event such as shutdown.When the material in hopper is many, the material being more than can in material return system is back to feed bin, but conveying supply doses if greater than the conveying capacity of feed back equipment, overflow event will occur, cause long downtimes time serious.
Summary of the invention
The technical problems to be solved in the utility model overcomes defect of the prior art exactly, proposes plasterboard stably feeding automatic control system, it is achieved the stability of feed, it is to avoid overflow, few material, the even generation of shutdown event.
In order to solve above-mentioned technical problem, this utility model provides plasterboard stably feeding automatic control system, carries including feed bin, conveying worm, bucket, belt conveyer scale, LOAD CELLS one, LOAD CELLS two, pipe reamer, rotary plow feeder and controller；Described LOAD CELLS one is arranged on the belt conveyer scale below hopper, and LOAD CELLS two is arranged far from the belt conveyer scale of hopper side；Pipe reamer and rotary plow feeder are provided with lattice wheel；Described controller is connected with LOAD CELLS one, LOAD CELLS two, pipe reamer lattice wheel and rotary plow feeder lattice wheel respectively.
Further, also include that level-sensing device, described level-sensing device are arranged on bucket and carry interior.
Further, described feed bin is two, and one of them is as standby feed bin.When there is the few situation of main bin blanking, controller controls standby feed bin lattice wheel and automatically runs and carry out feed supplement, it is ensured that the supply of feed and stable.
Further, controller is single-chip microcomputer or PLC.
Further, also including alarm device, described alarm device is connected with LOAD CELLS one, LOAD CELLS two, level-sensing device and controller respectively.
Further, display screen is also included.
This utility model is by LOAD CELLS and level-sensing device monitoring feeding coal and feeds back to PLC, utilizes the PID of PLC to be automatically adjusted pipe reamer, rotary plow feeder lattice wheel equifrequent, it is achieved the stability of feed, it is to avoid overflow, few material, the even generation of shutdown event.
Accompanying drawing explanation
Accompanying drawing 1 is structural principle schematic diagram of the present utility model.
Accompanying drawing 2 is circuit theory schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing 1,2, embodiment of the present utility model is described in detail.As shown in Figure 1, 2, plasterboard stably feeding automatic control system of the present utility model, carry including feed bin, conveying worm, bucket, belt conveyer scale, LOAD CELLS one, LOAD CELLS two, pipe reamer, rotary plow feeder and controller；Described LOAD CELLS one is arranged on the belt conveyer scale below hopper, and LOAD CELLS two is arranged far from the belt conveyer scale of hopper side；Pipe reamer and rotary plow feeder are provided with lattice wheel；Described controller is PLC, and it is connected with LOAD CELLS one, LOAD CELLS two, pipe reamer lattice wheel and rotary plow feeder lattice wheel respectively；Described level-sensing device is arranged on bucket and carries interior.This utility model also includes alarm device, and described alarm device is connected with LOAD CELLS one, LOAD CELLS two, level-sensing device and controller respectively.
Feed bin is two, and one of them is as standby feed bin.When there is the few situation of main bin blanking, controller controls standby feed bin lattice wheel and automatically runs and carry out feed supplement, it is ensured that the supply of feed and stable.
During work, by the measurement numerical value of LOAD CELLS on belt conveyer scale one, determine the doses in hopper, when doses tails off, be automatically increased the frequency of pipe reamer by the PID of PLC, the frequency of rotary plow feeder lattice wheel increases, the most therewith in order to increase the discharge quantity of feed bin simultaneously, in time material is supplemented and put in place, it is to avoid the generation of the few situation of material.And when doses becomes many, automatically reducing the frequency of pipe reamer by the PID of PLC, the frequency of rotary plow feeder lattice wheel reduces, the most therewith in order to reduce the discharge quantity of feed bin simultaneously, it is to avoid expect the generation of many overflows situation, it is ensured that stablizing of feed.
When level-sensing device detects that discharge quantity is excessive, bucket carry interior material too much time, stop in time the operation of reamer, rotary plow feeder lattice wheel frequency is controlled by PLC simultaneously, automatically frequency is gradually turned down, until out of service；If after bucket proposes the decline of interior doses, reamer starts automatically, rotary plow feeder lattice wheel Automatic Frequency increases to original frequency and runs.
