Problems solved by technology

[0003] The traditional method is to adjust the speed by changing the voltage value of the analog input. However, due to the limitation of industry development, there are many problems, such as easy to wear, short service life, not stable enough for long-term use, and many discrete components are used. Troublesome wiring, more fault points, and inconvenient maintenance
In addition, the output signal amplitude of the traditional speed regulation method is unstable, resulting in output noise, the speed regulation accuracy is not high enough, and the synchronization coordination is poor.

Abstract

The invention provides an extruding machine and a controller thereof. The extruding machine and the controller have the advantages that the synchronous speed regulating harmony is good, the service life is long, the stability is good, the used discrete component is less, the fault point is less, and the maintenance is convenient. The extruding machine comprises an extruding machine body, a frequency converter and the controller for controlling the frequency converter to carry out speed regulation on the extruding machine; the controller comprises a CPU (central processing unit) control chip as well as a power circuit, a main engine pulse coding circuit, an auxiliary engine pulse coding circuit, a synchronization pulse coding circuit, a start-stop control circuit, a voltage output circuit, a voltage input circuit and external equipment which are connected with the CPU control chip in an electronic control manner.

Description

technical field [0001] The invention relates to the technical field of extruders, in particular to extruders and controllers thereof. Background technique [0002] For the extruder industry, it often involves the start-stop and synchronous speed regulation of the main machine and auxiliary machine, and requires real-time display of the current and speed of the main machine and auxiliary machine. [0003] The traditional method is to adjust the speed by changing the voltage value of the analog input. However, due to the limitation of industry development, there are many problems, such as easy to wear, short service life, not stable enough for long-term use, and many discrete components are used. Wiring is troublesome, fault points increase, and maintenance is inconvenient. In addition, the output signal amplitude of the traditional speed regulation method is unstable, resulting in output noise, the speed regulation accuracy is not high enough, and the synchronization coordin...
