Description
Technical field
The utility model relates to a kind of synchronizer, is specifically related to a kind of slobbering machine and stretching-machine automatic synchronizing unit.
Background technology
At present, polyimide film is in manufacturing process, and especially when salivation was filmed, the rotating speed of slobbering machine and stretching-machine had strict requirement, and the difference of its rotating speed can affect the overall performance of finished films, reduces product quality; Existing synchronizer, have complex structure, a defect such as cost is high and net synchronization capability is poor.
Summary of the invention
The purpose of this utility model is exactly the defect that exists for prior art, provides a kind of simple in structure, reasonable in design, with low cost and slobbering machine and stretching-machine automatic synchronizing unit that net synchronization capability is good.
Its technical scheme is: slobbering machine and stretching-machine automatic synchronizing unit, comprise slobbering machine drive motors, stretching-machine drive motors, the first frequency converter, the second frequency converter, the first speed probe, the second speed probe and central processing unit, power supply is connected with the stretching-machine drive motors with the slobbering machine drive motors respectively with the second frequency converter by the first frequency converter, the first speed probe is arranged on the slobbering machine drive motors, and the second speed probe is arranged on the stretching-machine drive motors.Described the first speed probe is connected with an input of central processing unit by the first buffer circuit, the second speed probe is connected with another input of central processing unit by the second buffer circuit, and the output of central processing unit is connected with the control end of the second frequency converter by drive circuit.
Wherein, described central processing unit is single chip circuit or Programmable Logic Controller.
The utility model compared with prior art, has the following advantages: simple in structure, reasonable in design, the rotating speed of energy accurate synchronization slobbering machine and stretching-machine, improve the product overall performance.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, slobbering machine and stretching-machine automatic synchronizing unit, comprise slobbering machine drive motors 3, stretching-machine drive motors 5, the first frequency converter 2, the second frequency converter 4, the first speed probe 9, the second speed probe 11 and central processing unit 7, power supply 1 is connected with stretching-machine drive motors 5 with slobbering machine drive motors 3 respectively with the second frequency converter 4 by the first frequency converter 2, the first speed probe 9 is arranged on slobbering machine drive motors 3, and the second speed probe 11 is arranged on stretching-machine drive motors 5.Described the first speed probe 9 is connected with an input of central processing unit 7 by the first buffer circuit 8, the second speed probe 11 is connected with another input of central processing unit 7 by the second buffer circuit 10, and the output of central processing unit 7 is connected with the control end of the second frequency converter 4 by drive circuit 6.Described central processing unit 7 is single chip circuit or Programmable Logic Controller.The first frequency converter 2 is the frequency converter of manual adjustments.
During operation, manual adjustments the first frequency converter 2 is adjusted the rotating speed of slobbering machine drive motors 3 to requiring rotating speed to get final product.When equipment in when operation, while causing for a certain reason the rotating speed of slobbering machine drive motors 3 to change, the first speed probe 9 and the second speed probe 11 send to central processing unit 7 with the rotating speed of slobbering machine drive motors 3 and stretching-machine drive motors 5, contrast by central processing unit 7 is processed, its output is controlled the second frequency converter 4 by drive circuit 6, thereby the rotating speed of restrained stretching machine drive motors 5, make the synchronization of itself and slobbering machine drive motors 3.
The utility model is simple in structure, and is reasonable in design, and the rotating speed of energy accurate synchronization slobbering machine and stretching-machine, improved the product overall performance.
