Description
Technical field
The invention belongs to online carding force control fields, are related to a kind of carding machine intelligent control side based on online carding force
Method and device.
Background technique
Metallic card clothing is the core component of carding machine, in carding process, shape of the metallic card clothing in a service life
State variation will directly affect the carding effect of carding machine.In daily production, people often carry out detection side using to metallic card clothing
Formula improves its carding effect in turn to control the carding process of carding machine, typically occurs in following two process to the detection of needle cloth
In: (1) in needle cloth production process it is detected；(2) it is detected in needle cloth use process.It is produced in needle cloth
The prior art detected in the process to it improves needle cloth produced mostly using optical technology as technical foundation, with this
Quality, to guarantee carding effect when combing, such as patent ZL200820237541.6 using camera image by detecting
The needle cloth quenched on line liquidate to achieve the purpose that carry out quality testing to it；Patent ZL201120239523.3 passes through in metal
Needle cloth, which rushes on line of quenching, to carry out having metallic card clothing very without breakpoint connector in quenching hardness detection realization entire volume needle cloth production process
Good consistency, stability and integrality, but the above method only can guarantee the quality of the metallic card clothing before cotton carding, the comb of carding machine
During reason, metallic card clothing can often be worn, and the carding effect of carding machine will decline at this time, and the above method can not continuously have
The carding effect of the guarantee carding machine of effect.The method detected in needle cloth use process to it includes directly or indirectly two kinds
Method: direct method needs to tear open machine and carries out subjective sensing, detection to the sharpness and uniformity of cylinder or licker-in surface package needle cloth
When need to stop and interrupt production, and testing result human factor is larger；Indirect rule is by periodically reflecting carded sliver sample detection
The use state of needle cloth, representativeness of sample is not high and fault reaction lags, and a large amount of unqualified carded slivers is made to flow into subsequent processing.Separately
Outside, it since the combing of carding machine separates the detection away from small and relative closure, for the use state of needle cloth, not yet passes at present
The mode of line detection is realized.The intelligent control method of carding machine is mainly to control to the intelligence of carding machine autoleveller process at present
System, the carding machine intelligent control method of the service life based on metallic card clothing not yet occur.
It would therefore be highly desirable to need to study a kind of making based on needle cloth for the carding effect of guarantee carding machine for capableing of continuous effective
With the carding machine intelligent control method in period.
Summary of the invention
The purpose of the present invention is overcoming deficiency in the prior art, a kind of carding machine intelligence based on online carding force is provided
Control method and the device for realizing this method.The present invention is detected to the needle cloth of working condition after upper machine, by cotton carding
The tracking of the online carding force of machine, comparison theoretical standard comb force curve, can comb state and change to the carding clothing of carding machine
Change is characterized, and then the operating status of real-time monitoring carding machine, realizes intelligent control.
In order to achieve the above object, present invention employs the following technical solutions:
A kind of carding machine intelligent control method based on online carding force, the real-time carding force of on-line testing carding machine, and
It is compared with real-time theoretical standard carding force, the operating status of carding machine is regulated and controled according to comparing result, realizes intelligent control；
