Abstract
A kind of pressure tester that can improve accuracy, practicality and directiveness.Pressure tester is made up of ultra-thin sensor, control box and low power consumption liquid crystal display screen.Sensor is placed between roller and rubber roll, and the rubber roll of reel cage is depressed, and sensor is delivered to the degree of pressure being subject to the processor in control box, by conversion process, the pressure value finally measured with liquid crystal display.The roller loading of spinning equipment drafting system that can be directly to being used is tested, and can strengthen actual accuracy, practicality and the directiveness of test equipment；Live test immediately, method is simple, without dismounting, saves trouble quick, structure is concentrated, easy to use.
Description
Technical field
The present invention relates to a kind of pressure tester, especially can accurately test Weaving device roller and rubber roll actual pressure
Pressure tester.Background technology
The research and development of spinning drafting system are upper century-old in the world, in these years, the pressurization principle of spinning drafting system, pressuring machine
Structure, pressing members and material have outstanding contribution for the progress and development of spinning technique, but in the pressurization of spinning drafting system
Mechanism, the testing research of pressing members and material and context of detection are also limited to emulation mode.
The roller loading tester used in the world mainly has three types：Electricity under simple roller loading tester, machine
Pendulum Weighting Arm System tester on sub- Pendulum Weighting Arm System tester, machine.Three types can be tested roller loading, using simulation glue
Roller or rubber roll material object are tested, and can reflect the degree of roller loading from different angles.It is to use more satisfactory sieve at present
Pressure tester.
Simple roller loading tester is to represent original rubber roll using the rubber roll of one grade of (two) certain diameter, is placed on machine
Roller pressure is directly measured by spring pressure gauge.Because top roller diameter is fixed, therefore practical top roller diameter can not be reflected
Pressure.
Electronics Pendulum Weighting Arm System tester includes AFA-IV types digital display reel cage dynamometer under machine and YDF-1 type thickness yarns integrally shake
Frame pressure tester.The reel cage do not installed or pulled down is positioned on instrument test platform by AFA-IV types when testing, force cell
Mounted in top, upper end tester is moved with spanner, tests the pressure of three row rollers respectively, but three row rollers can not detect simultaneously.
Force value sensor is mounted on simulation bottom roll by YDF-1 types, after the reel cage do not installed or pulled down is loaded on into reel cage spindle nose, by setting
Ratch adjustment roller positioning seat, can use rubber roll in kind or the top roller of normal diameter, while three row rollers of detection
Pressure.Its defect is that the testing result that draws of detection is not True Data, is not identical environment, state and pressure under machine and on machine
Power, pressure necessarily changes after reel cage is reinstalled.
Pendulum Weighting Arm System tester includes integral cradle pressure on reel cage dynamometer on AF111 type machines and YDF-2 type machines on machine
Tester.AF111 types by shaft core of the force cell loaded on measurement rubber roll, fixed by measurement top roller diameter, and measurement rubber roll is put
In Pendulum Weighting Arm System pawl on machine, roller pressure can directly be measured by taking reel cage off, and data are by liquid crystal display, due to being that fixed rubber roll is straight
Footpath test pressurization, it is inconsistent with practical diameter on machine, unknown errors can be caused.YDF-2 types are added using simulation top roller (rubber roll)
The pressure transmission rod of holding file mandrel height is pressed, instead of former top roller shaft core, bears Pendulum Weighting Arm System pressure, and transmits force value to biography
On sensor, because it uses simulation rubber roll, the height that mandrel can be gripped by actual use top roller diameter sets pressure transmission rod height
Degree, makes test pressure value meet actual pressure.Have a disadvantage in that：It is not that identical material is substituted using material object, causes detection to be tied
The comparativity of fruit has very big unknown errors, and the size differed carries out estimating the error that can increase with actual pressure.
The content of the invention
In order to overcome roller loading that existing roller loading tester can not be tested directly under spinning equipment virtual condition
Deficiency, the present invention provide a kind of pressure tester, the sensor thickness and spinning equipment roller of the pressure tester and rubber roll
Folding gap is equal or close, the roller loading pressure that can not only be effectively tested under virtual condition, and the weight of roller pressure
Existing property is relatively good, so as to quick, reality, accurately gives roller loading pressure.
The technical solution adopted for the present invention to solve the technical problems is：Device is by ultra-thin sensor, control box and low work(
Consume LCDs composition.Sensor is placed between roller and rubber roll, the rubber roll of reel cage is depressed, sensor is the pressure being subject to
Range degree is delivered to the processor in control box, by conversion process, the pressure value finally measured with liquid crystal display.
The invention has the advantages that directly the roller loading of the drafting system on the spinning equipment that uses can be carried out
Test, actual accuracy, practicality and the directiveness of test equipment can be strengthened；Live test immediately, method is simple, without tearing open
Unload, save trouble quick, structure is concentrated, easy to use.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram of the present invention.
Fig. 2 is the structural map of pressure tester embodiment.
1. sensor in figure, 2. control box, 3. handles, 4. wires, 5. rollers, 6. rubber rolls, 7. internal circuits and liquid crystal
Display screen.
Embodiment
In Fig. 1, pressure tester is by sensor (1), control box (2) and LCDs (7), sensor and control box
Between coupled with connecting wire.
In fig. 2, Fig. 2 a are sensors and control box is front；Fig. 2 b are sensors and control box is side.Pass
Sensor (1) is positioned between roller (5) and rubber roll (6), is deformed after rubber roll is pressurized, caused pressure change is by sensor
(1) processor in control box (2) is delivered to by wire (4), by signal amplification and conversion process, finally uses liquid crystal display
The pressure value that screen (7) display measures.
Claims (1)
1. a kind of pressure tester, it is made up of ultra-thin sensor, control box and low power consumption liquid crystal display screen；It is characterized in that：Sensing
Device is placed between roller and rubber roll, and the rubber roll on reel cage is depressed, and the degree of pressure being subject to is delivered to control box by sensor
In processor, by conversion process, the pressure value measured is finally shown with LCDs.
