Description

A kind of cumulative press mechanism of lapper lap based on electrohydraulic proportion technology
Technical field
The utility model belongs to mechanical engineering technical field, relates to a kind of textile machine, is specifically related to a kind of cumulative press mechanism of lapper lap based on electrohydraulic proportion technology.
Background technology
Lapper rolling compression system is an important component part on the Blowing-carding Unit group, and its effect is to apply certain pressure in the process that lap forms, and makes lap rolling process pressure constant, and cotton bed thickness is thin evenly, for slivering is laid a solid foundation.Existing lap pressue device is to adopt machinery or pneumatic pressuring method, exists the unsettled shortcoming of pressure process.
Traditional mechanical type lap pressue device is made of weight and other mechanical transmissioning piece, cotton layer by calender roller output is sent to lap roller through leading the cotton roller transmission, and plugs the lap of making constant weight around lap, and the lap skewer is made by glass-reinforced plastic material, quality is light, and is easy to use.In the rolling process, lap is driven and turns round by a pair of lap roller and a writing that surpasses all the others roller friction, also is subject to the pressure of writing that surpasses all the others roller simultaneously, makes coiling closely solid and reliable.Because the diameter of lap changes in the rolling process, so the writing that surpasses all the others roller is wanted and can be moved up and down.Spindle nose is respectively charged into left and right pressure hook body when writing that surpasses all the others roller two ends, and the bottom of pressure hook is tooth bar, and respectively with a pinion, the pinion common apparatus at two ends is guaranteed the synchronization lifting at writing that surpasses all the others roller two ends in a fixing rotating shaft.Lap diameter in winding process increases gradually, forces lap rod and lap pressure hook to rise gradually, and passes through the train transmission to braked wheel.The braking action of weight because braked wheel is subject to pressurizeing will make its rotate, and must overcome brake force, thereby produces pressure.When the lap diameter continue to increase it is upwarded pressure when overcoming brake force, the lap pressure hook just rises, and can make closely reliable that lap reels.
The pressure that the cumulative press mechanism of mechanical type is subject in the process that the lap diameter changes from small to large has following two kinds variation:
(1) with the increase of lap diameter, pressure diminishes gradually;
(2) intermitten because of braked wheel produces the pressure variation, braked wheel was motionless when the counter-force that makes progress when lap was not enough to overcome the stiction of braked wheel, lap arbor pressure increases with the lap continuous reeling, until pressure is increased to when being enough to overcome brake force, braked wheel turns round suddenly, and this moment, pressure reduced.When pressure was reduced to the frictional force that can not overcome braked wheel, braked wheel is stall again, and pressure increases again gradually, and pressure initiation periodically changes.
In order to eliminate the shortcoming of mechanical type pressuring method, some producers have adopted pneumatic control lap compression system both at home and abroad, and its core is to use the cumulative pressure valve control of mechanical type gas control pressure regulator valve, and control enters the pressure of pressurized cylinder, realizes the pressurization to the lap pressure hook.Because the cumulative pressure valve of mechanical type can be heightened the air pressure in the pressurized cylinder when the lap diameter increases, guarantee that pressure hook institute plus-pressure increases gradually in the lap rolling process, improved the completed state of lap.But because the compressibility of gas is large, pressure transient in the course of work so just makes the lap Lapping Quality be difficult to guarantee.In addition, the operating pressure of baric systerm is also low, and when lap need add larger pressure, cylinder need be done very greatly, has increased the cost of making and difficulty is installed.Because it is high that the control valve in the pneumatic system requires, general amateur manufacturer production is had any problem, difficult quality guarantee, and the effect that impact is used, and also pneumatic system need to configure air compressor, increased the cost that uses.
Summary of the invention
