Abstract

The utility model relates to a bar on-line detecting instrument for a carding machine, which belongs to the auxiliary equipment of a textile machine and is used for detecting the thick or thin continuous change conditions of a bar output by an on-line carding machine. The utility model is characterized in that the detecting instrument is composed of a pair of press rollers, a magnetic steel installed on the top end of a connecting rod of a bearing of the upper press roller, a linear Hall sensor fixedly installed just above the magnetic steel, a PLC of which one end is connected to the sensor by a conducting wire, and the other end is connected to a display and/or a printer, wherein the lower press roller is fixed and the upper press roller is moveable. The press rollers are installed on and below a bar output by a carding machine. The utility model has the advantages of simple structure, convenient installation and use, low cost, stable performance and exact detection; the utility model can display the thick or thin change condition of the on-line bar in real time and visually.

Description

The dried on-line detector of carding machine bar

The dried on-line detector of a kind of carding machine bar belongs to the auxiliary equipment technical field of textile machine, is mainly used on production line continuous detecting by the thickness situation of change of the carded sliver of carding machine output, for the automatic control of spinning provides foundation, and then improves cotton-spinning quality.

In the prior art, find no identical with the utility model or akin technology by retrieval.At present,, the controller of other forms of sensor is only arranged, but its complex structure costs an arm and a leg both at home and abroad.

It is a kind of simple in structure that the purpose of this utility model is to provide, and cost is low, and is economical and practical, stable and reliable for performance, can preset controlling value, again can be the dried on-line detector of carding machine bar that dynamically shows intuitively or depict in the dried situation of lines.

When under unsteady state, moving according to carding machine, to cause the actual conditions of the dried fluctuation of bar and the operation principle of linear hall sensor, at existing questions in the prior art, basic design of the present utility model is: do at the bar that carding machine is exported, adorn a magnet steel by last moving fixed a pair of pressure roller down down, in order to gather signal, the linear hall sensor of a built-in linear amplifying circuit of about 2.5mm eminence fixed installation directly over this magnet steel again, in order to will go up that pressure roller does along with bar that thickness changes and the fluctuation that causes converts voltage signal to, and linear voltage exported to thereafter microprocessor PLC, output v-t curve image after little processing, by the display demonstration or by printer prints, perhaps start at the same time, thereby realize purpose of design.

The dried on-line detector of carding machine bar described in the utility model, it is characterized in that this detector by be loaded on that bar that carding machine 1 exported is done 2 upper and lower last pressure rollers 3 and lower compression roller 4 and the magnet steel 6 on connecting rod 5 tops that link to each other with the bearing 11 of last pressure roller 3, fixedly be loaded on directly over this magnet steel 6 and apart from its only 2～3mm linear hall sensor 7 be connected above-mentioned linear hall sensor 7 by lead one end, the PLC8 formation of other end connection display device 9 and/or print device 10.

Above-mentioned lower compression roller 4 is installed on the frame, and last pressure roller 3 then is loaded on can be in an elongated slot up and down on the above-mentioned bearing 11 of fine motion, and wherein the bearing 11 of an end connects an above-mentioned connecting rod 5, and above-mentioned magnet steel 6 is equipped with by cylinder sleeve 12 in its top.

The utility model has the advantages that simple in structure, easy to install, cost is low, easily promotes, can be in real time, the surge detection of caused dried thickness is come out when exactly the carding machine unstable state being moved, and this fluctuation situation lifelike image ground can also be shown or depict.

Accompanying drawing is that each parts of one of the utility model most preferred embodiment are installed configuration schematic diagram.

In conjunction with the accompanying drawings and most preferred embodiment, further describe architectural feature of the present utility model as follows: bar that carding machine 1 is exported do 2 on, under a pair of irony is installed, chrome faced special diameter is the pressure roller of 70mm, wherein lower compression roller 4 is fixed on the frame, last pressure roller 3 then is contained in can be in an elongated slot up and down on the bearing 11 of fine motion, so that last pressure roller 3 can be with the variation of the dried thickness of bar and fluctuation up and down, the bearing 11 of its end connects a columniform connecting rod 5, its end is adorned a magnet steel 6 by a cylinder sleeve 12, high 2.5mm place directly over this magnet steel 6, fixedly mount the linear hall sensor 7 of a commercially available CS3500 series built-in linear amplifying circuit, its output connects the Japanese OMROM product SYSMAC CAMIA of a company type PLC microprocessor 8 by lead, and the output of this PLC8 connects a miniature industrial display 9 and an industrial small size printer 10 by lead again.Like this when carding machine unstable state operation causes that bar is done the thickness fluctuation, last pressure roller 3 just drives magnet steel 6 and fluctuates up and down, even the distance between magnet steel 6 and the Hall element 7, just the magnetic field of magnet steel changes, convert this fluctuation to voltage signal by sensor 7, after amplifying, export to PLC.

Change as present embodiment:

1, material and the overall dimensions that go up lower compression roller can suitably change, and the vertical interval between magnet steel and the sensor can be adjusted between 2～3mm;

2, the model of sensor can suitably change, and for example can use inductance type transducer etc. instead;

3, the model of microprocessor and display, printer can be selected according to actual needs.
