Description

Nonwoven production with vertical weight uniformity at thread detector

Technical field

The utility model relates to a kind of nonwoven fabric and makes the field, a kind of specifically nonwoven production with vertical weight uniformity at thread detector.

Background technology

Reach the weight requirement of product needed after the shredding of acupuncture adhesive-bonded fabric process, combing, folded net, the acupuncture, wherein the control of product and vertical weight uniformity are very important quality index.The present stability that the grammes per square metre control and the control of vertical grammes per square metre of adhesive-bonded fabric is mainly depended on feeding machine self can't realize timely adjusting, often need finished product is carried out realizing the grammes per square metre adjustment again after grammes per square metre analyzes.

Production process is as follows: the synthetic staple that is compressed into bag through open the hair bucket, opener tears the fibrous mass into small size, the fluffy increase of fibrous mass volume is convenient to further decompose the fibrous mass of littler volume, and various component fibers are rolled into a ball through mixing chamber and mixed uniformly to next procedure circulation (above-mentioned is shredding); From the shredding operation, fibrous mass blows to temporary transient cotton storage tank through blower fan, after entering skewed slot concussion feeding machine, form the fibrage of certain thickness, density, enter carding machine again, carding machine is decomposed into fritter shape fibrous mass the filament of free state, and (this stage is subjected to the influence of feeding machine self precision, and the cotton layer variable density of input carding machine then exported single net changes in weight to form the continuous fibers net of constant weight, width, thereby influence the vertical weight uniformity of product, this operation is the combing operation); After single net enters cross lapping machine, carry out reciprocal crossing stack, form overlapping cotton layer (this operation is folded net) near required thickness, width; The puncture of the cotton layer process of folded net pricker is reinforced, and reaches the thickness and the tightness that need; According to demand cut, rolling, packing.Its weak point is: because in actual production, whole process is streamline production, be that the grammes per square metre reflection all embodies in the rolling stage, product carried out the sample measurement can obtain weight indicator that continuous measurement could obtain vertically evenly index, belong to reflection afterwards, will have the following disadvantages like this: (1), owing to after product forms finished product, could obtain reference index by the sample test, so reflect hysteresis, especially the longitudinal uniformity index often needs the long time; (2), the acquisition of sample belongs to destructive testing, continuously vertical sample test increase percent defective; Secondly because the reference index acquisition is untimely, occur the debugging waste product easily, increase percent defective; (3), this flow process lacks the reflection of online reference index, vertically evenly index depends on detection to sample, because sample obtains to obtain at interval for artificial, can't realize uninterrupted reflection, there is hidden danger of quality interim, vertically the irregular defective of grammes per square metre is not easy to find.

Summary of the invention

It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and can in time react the vertical weight uniformity of nonwoven fabric, detect accurately and timely nonwoven production with vertical weight uniformity at thread detector.

In order to reach above purpose, the technical scheme that the utility model adopted is: this nonwoven production with vertical weight uniformity at thread detector, constitute by base and fixed mount, the fixing upper holder respectively at the two ends of base, it is characterized in that: all be provided with the LOAD CELLS probe in the upper end of each fixed mount, the weigh two ends of bar are placed on respectively on the LOAD CELLS probe of both sides, and two LOAD CELLSs probes are connected with weighing balance by lead respectively, and weighing balance is provided with display screen.

The beneficial effects of the utility model are: simple in structure, cost is low, feedback in time, easy and simple to handle, owing to belong to online uninterrupted detection, obtain vertical grammes per square metre fluctuation data at the right time, need not to rely on merely sample detects, the operating personnel in time carries out the feed quantity increase and decrease according to video data, can not adjust before the moulding fully at product, greatly reduces the waster rate.

The specific embodiment

Make the utility model with reference to accompanying drawing 1,2.This nonwoven production with vertical weight uniformity at thread detector, constitute by base 7 and fixed mount 1, the fixing upper holder 1 respectively at the two ends of base 7, it is characterized in that: all be provided with LOAD CELLS probe 3 in the upper end of each fixed mount 1, the weigh two ends of bar 2 are placed on respectively on the LOAD CELLS probe 3 of both sides, two LOAD CELLS probes 3 are connected with weighing balance 4 by lead 5 respectively, weighing balance 4 is provided with display screen 6, so that the signal of the LOAD CELLS probe 3 nonwoven fabric weight that measure is delivered in the weighing balance 4, program by weighing balance 4 with two detected values stacks after, be presented on the display screen 6, because weighing balance 4 and LOAD CELLS probe 3 are all prior art, so seldom state, the numerical value that the staff shows according to display 6, observe the fluctuation range of nonwoven fabric weight, as long as the numerical value that shows does not exceed fluctuation range, just illustrate that nonwoven fabric weight uniformity is qualified, if the numerical value that shows has exceeded fluctuation range, will according to circumstances adjust the feeding parameter in good time, the cotton layer variable density of control input carding machine, carry out online adjustment, stop nonwoven fabric and a large amount of substandard products occur.

During use, after nonwoven fabric goes out the first road needing machine and is the pre-pricking machine pressure roller, again through tension bracket, slip over from the bar 2 of weighing again, arrive main-needling machine feeding roller at last, the uniform tension in order of nonwoven fabric in the meantime, so carry out online weighing between tension bracket and main-needling machine feeding roller, numerical value is relatively stable, because the smooth surface of the bar 2 of weighing, frictional force can be ignored, when the nonwoven fabric process is weighed bar 2 like this, pass the signal along to weighing balance 4 by LOAD CELLS probe 3, display 6 just shows the weight at any time of nonwoven fabric, the fluctuation of these data is the fluctuation of vertical grammes per square metre uniformity, increases and decreases with reference in time adjusting feeding numerical value with this.
