Description
Technical field
This utility model relates to a kind of packing machine motor frequency conversion brake unit, it is adaptable to chemical fibre industry packing shop is given birth to automatically
Produce the mode of braking that on line, packing machine motor is novel.
Background technology
Along with the packaging facilities advanced technology of modern chemical fibre textile industry, along with the lifting of the productivity, original packaging mould
Formula can not meet the production equipment of modernization, so while capacity packing promotes, also causing our equipment
No small test, the workload of over loading so that original motor brake block life-span has a greatly reduced quality, a brand-new Motovario
Motor, the life-span used on our baling line only has about 5-6 month (every day brakes number of times at 12500 times), and 4 sets
A total of 24 motors of machine are so to run, the price of every brake motor about 2500 RMB, the fault brought
Rate and loss are the most fearful, so we need a good method to bring to solve this because mode of braking is not enough
Problem.
Summary of the invention
For the drawbacks described above overcoming the packaging facilities of existing textile of chemical fibre industry to exist, this utility model provides a kind of letter
Single, convenient, stable without impact so that original packaging production line runs more smooth packing machine motor frequency conversion braking dress
Put.
The technical solution adopted in the utility model is:
Packing machine motor frequency conversion brake unit, including frame and rack-mounted electric operation switch board, described
Electric operation switch board in motor, PLC and chopper are installed, it is characterised in that: also include being fixedly mounted on
On electric operation switch board by the converter of DC injection braking, the outfan of described chopper and the three of described converter
Phase input correspondence connects, and described converter is connected with three-phase power line, and the output of described PLC is just transferred the letter
Number port and output reverse signal port respectively with the rotating forward terminal of described converter and invert terminal and be connected.
This utility model removes the brake of original brake motor, solves motor system by the way of attached with frequency converters
Dynamic problem.Its principle is: when converter output frequency is close to zero, and when motor speed is reduced to certain numerical value, converter changes
In asynchronous motor stator winding, it is passed through direct current, and magnetic field produced by it will be constant stationary magnetic field, locus, and
Rotor continues because of inertia to rotate with the speed of its original, and now, the rotor of rotation cuts this stationary magnetic field and produces braking
Torque, the kinetic energy of system storage is converted into power consumption in the rotor loop of motor, and then arrives the effect of motor fast braking
Really.So utilize DC injection braking motor steadily without impact, stop accurately, reduce the fault rate of whole piece packaging facilities, reduce into
While Ben, also improve production efficiency.
The beneficial effects of the utility model are embodied in:
This utility model frequency conversion DC injection braking, simple in construction, safe and reliable, facilitate durable, daily production provides effect
Rate ensures, compensate for the deficiency of original traditional motor brake block braking, reduces attendant's labor intensity, be greatly reduced
The maintenance cost of company so that successor company all of packing machine motor braking mode also uses this programme, the most also
Arrive the accreditation of German packing machine producer.Using the motor after novel brakes, export the most stable, packaging quality has guarantor
Barrier, fundamentally solves the product packaging caused because motor stops incessantly lack of standardization, protects the fundamental interests of company.
Accompanying drawing explanation
Fig. 1 is this utility model braking principle figure.
Detailed description of the invention
With reference to Fig. 1, packing machine motor frequency conversion brake unit, including frame and rack-mounted electric operation control
Cabinet processed, is provided with motor 1, PLC 2 and chopper 3 in described electric operation switch board, also include being fixedly mounted on
On electric operation switch board by the converter 5 of DC injection braking, the outfan of described chopper 3 and described converter 5
Three-phase input end correspondence connects, and described converter 5 is connected with three-phase power line 4, the output of described PLC 2
Rotate forward signal port and output reverse signal port is connected with rotating forward terminal and the reversion terminal of described converter 5 respectively.
The present embodiment removes the brake of original brake motor, solves motor braking by the way of attached with frequency converters
Problem.Its principle is: when converter output frequency is close to zero, when motor speed is reduced to certain numerical value, and converter alters course
Asynchronous motor stator winding is passed through direct current, and magnetic field produced by it will be constant stationary magnetic field, locus, and turn
Son continues because of inertia to rotate with the speed of its original, and now, the rotor of rotation cuts this stationary magnetic field and produces braking and turn
Square, the kinetic energy of system storage is converted into power consumption in the rotor loop of motor, and then arrives the effect of motor fast braking.
So utilize DC injection braking motor steadily without impact, stop accurately, reduce the fault rate of whole piece packaging facilities, reduce cost
Meanwhile, production efficiency is also improved.
Content described in this specification embodiment is only enumerating of the way of realization to inventive concept, of the present utility model
Protection domain is not construed as being only limitted to the concrete form that embodiment is stated, protection domain of the present utility model also and in this
Skilled person according to this utility model design it is conceivable that equivalent technologies means.
