Abstract

The utility model relates to a self-regulation regularity machine for blowing-carding system of cotton spinning, in particular to a self-regulation regularity machine with a cotton strip control. The utility model is characterized in that: a cotton thickness test sensor is comprised; a detector of the cotton strip thickness test sensor is pressed on the cotton strip; and the down-lead of an output end is connected with the input end of the regularity machine. The utility model transfers the cotton strip thickness test signal into the mini-processor in the regularity machine for handling, and then is transferred into a transducer together with the feeding cotton electromotor voltage value obtained by accounting the handling values of each processor signal from the regularity machine to control the rotational speed of the feeding cotton electromotor, thus the card silver with quantity is kept and the purpose of reducing the deflect and uneven weight of the card silver is achieved.

Description

The autoleveller of band sliver control

Technical field

The utility model relates to a kind of autoleveller of cotton spinning blowing-carding system, particularly a kind of autoleveller with sliver control.

Technical background

Autoleveller is that the cotton spinning blowing-carding system solves the not important device of even deviation of weight of carded sliver weight.At present, the autoleveller that uses on carding machine is closed-loop control, only detect the input cotton layer thickness and revise the deviation that various fluctuations cause automatically, but since closed-loop control self system to limit its output calibration fragment longer, the thickness fluctuation of output sliver is bigger, particularly causing the main disturbance of sliver---cotton layer feeding is irregular, the time of control is longer, after than long segment, leveling role is arranged, simultaneously, also need pass through multiple mechanical device by importing cotton layer to sliver output, the inhomogeneous autoleveller of output sliver that causes owing to fluctuation in this process is just uncontrollable, thereby influence the quality of output sliver, cause sliver heavy irregular excessive.

Summary of the invention

In view of there are the problems referred to above in prior art, the utility model provides a kind of autoleveller with sliver control, detection, processing, computing have been increased to output sliver thickness, make closed-loop control realize complex loop control, the open loop that utilizes complex loop has remedied the deficiency of closed-loop control to irregular detection effect of cotton layer feeding and neat and well spaced than the short-movie section.The technical solution of the utility model is: a kind of autoleveller with sliver control, include neat and well spaced device, it is characterized in that: also comprise a sliver thickness detecting sensor, the probe of described sliver thickness detecting sensor suppresses on sliver, and the lead-in wire of its output links to each other with the input of neat and well spaced device.

Characteristics of the present utility model are, because irregularity and the adjustment of adopting complex loop control to detect sliver have immediately remedied the deficiency of closed-loop control for the output valve of cotton motor, reached the heavy irregularity that improves sliver, make the autoleveller system that leveling role preferably be arranged, satisfied the demand that cotton spinning is produced.

Description of drawings

Fig. 1 is the utility model connection diagram, and as Figure of abstract.

Fig. 2 is the utility model electrical schematic diagram.

Among the figure: 1. sliver thickness detecting sensor, 2. neat and well spaced device, 3. lead-in wire.

The specific embodiment

As shown in Figure 1, the utility model selects for use the B3 magnetic sensor as sliver thickness detecting sensor 1, be fixed on the support of sliver output place of carding machine, and its flat contact is suppressed on sliver, the output lead-in wire 3 of sliver thickness detecting sensor 1 is connected on the input of neat and well spaced device 2.

As shown in Figure 2, the sliver thickness detection signal enters neat and well spaced device 2, at first removes interfering signal through filter circuit, enters the 87196KC cpu chip and carries out the A/D conversion, calculates to the cotton motor tachometer value under the support of program storage.

The autoleveller that the band sliver thickness detects, a left side that also has cotton layer simultaneously, the right lateral position displacement sensor, the doffer speed sensor, also import in the neat and well spaced device for the signal of cotton motor velocity sensor collection simultaneously, processing through the 87196KC cpu chip, computing provides give the cotton motor tachometer value after sliver thickness detecting sensor calculated signals give that the cotton motor tachometer value formed complex loop control give the cotton motor tachometer value through isolating, shaping, D/A conversion back is to the cotton motor voltage signal, be transported to frequency converter, Frequency Converter Control gives the rotating speed of cotton motor to regulate the cotton speed of giving of cotton layer.

Claims

1. autoleveller with sliver control, include neat and well spaced device (2), it is characterized in that: also comprise a sliver thickness detecting sensor (1), the probe of described sliver thickness detecting sensor (1) suppresses on sliver, and the lead-in wire of its output (3) links to each other with the input of neat and well spaced device (2).
