Abstract

Provided is a pressure test instrument which is capable of improving accuracy, practicability and instructive performance. The pressure test instrument is composed of an ultra-thin sensor, a control box and a low-power-consumption liquid crystal display screen, wherein the sensor is arranged between a roller and a rubber roll, the rubber roll of a cradle is pressed down, the sensor transmits the received pressure degree to a processor in the control box, and detected pressure value is displayed through the liquid crystal display screen after a switching process. The roller of a traction device of spinning equipment which is used can be directly tested in a pressurization mode, and the actual accuracy, practicability and instructive performance of the tested equipment are improved. The test can be carried out on site, the method is simple, the equipment does not need to be detached, and therefore the pressure test instrument is labor-saving, rapid, concentrated in structure, and convenient to use.

Description

A kind of pressure tester

Technical field

The present invention relates to a kind of pressure tester, especially can accurately test the pressure tester of Weaving device roller and rubber roll actual pressure.

Background technology

The research and development of spinning drafting system are existing century-old in the world, in these years, the pressurization principle of spinning drafting system, pressing mechanism, pressurization parts and material are that progress and the development of spinning technique has outstanding contribution, but also are confined to emulation mode in the pressing mechanism of spinning drafting system, testing research and the context of detection of pressurize parts and material.

The roller applied voltage test instrument that adopts in the world mainly contains three types: Pendulum Weighting Arm System tester on electronics Pendulum Weighting Arm System tester, machine under simple and easy roller applied voltage test instrument, machine.Three types can be tested the roller pressurization, adopts simulation rubber roll or rubber roll material object to test, can be from the degree of different angle reflection roller pressurizations.It is the desirable roller pressure test instrument of present usage comparison.

Simple and easy roller applied voltage test instrument is to adopt the rubber roll of one grade of (two) certain diameter to represent the former rubber roll of using, and is placed on machine and directly records roller pressure by the spring tensimeter.Because top roller diameter is fixed, therefore can't reflect the pressure of practical top roller diameter.

Under machine, electronics Pendulum Weighting Arm System tester comprises AFA-IV type digital display reel cage dynamometer and YDF-1 type thickness yarn pressure tester with integral cradle.The reel cage of will not installing or pulling down during the test of AFA-IV type is positioned on the instrument test platform, and force cell is contained in the top, moves the upper end tester with spanner, test respectively the pressure of three row rollers, but three row rollers can not detect simultaneously.The YDF-1 type is contained in power value sensor on the simulation bottom roll, after the reel cage of not installing or pulling down is loaded on the reel cage spindle nose, adjusts the roller positioning seat by the ratch of setting, and the top roller of available rubber roll in kind or normal diameter detects the pressure of three row rollers simultaneously.Its defective is that to detect the testing result draw be not True Data, and under machine and be not identical environment, state and pressure on machine, pressure must change after reinstalling reel cage.

On machine, the Pendulum Weighting Arm System tester comprises on AF111 type machine pressure tester with integral cradle on reel cage dynamometer and YDF-2 type machine.The AF111 type is loaded on force cell in the axle core of measuring rubber roll, the measurement top roller diameter is fixed, to measure rubber roll and be placed in Pendulum Weighting Arm System pawl on machine, take reel cage off and can directly record roller pressure, data are by liquid crystal display, owing to being fixing glue roller diameter test pressurization, inconsistent with practical diameter on machine, can cause unknown errors.The YDF-2 type adopts the pressure of simulation top roller (rubber roll) pressure gripping shelves mandrel height to transmit bar, replace former top roller axle core, bear Pendulum Weighting Arm System pressure, and transmit the power value to sensor, because it adopts the simulation rubber roll, can transmit the bar height by the height setting pressure that reality uses top roller diameter to grip mandrel, make the realistic pressure of test pressure value.Its defective is: be not that identical material substitutes the use material object, cause the comparability of testing result that very large unknown errors is arranged, not identical size is estimated the error that can increase with actual pressure.

Summary of the invention

Can not directly test the deficiency of the roller pressurization under the spinning equipment virtual condition in order to overcome existing roller applied voltage test instrument, the invention provides a kind of pressure tester, the folding gap of the sensor thickness of this pressure tester and spinning equipment roller and rubber roll equates or is close, can not only effectively test the roller moulding pressure under virtual condition, and the reappearance of roller pressure is relatively good, thus fast, actual, provided the roller moulding pressure accurately.

The technical solution adopted for the present invention to solve the technical problems is: device is comprised of ultra-thin sensor, control enclosure 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 the degree of pressure that the sensor handle is subject to is delivered to the processor in control enclosure, through conversion process, and the force value that finally records with liquid crystal display.

The invention has the beneficial effects as follows, can directly test the roller pressurization of the drafting assembly on the spinning equipment that uses, can strengthen actual accuracy, practicality and the directiveness of testing apparatus; On-the-spot instant test, method is simple, need not dismounting, saves trouble quick, and structure is concentrated, and is easy to use.
