Abstract
The utility model relates to a parallel pressure device for a beam warper with quick delivery valve, and consists of two pressurized cylinders 4, 5, an electromagnetic valve 2 and a connected gas circuit. The cylinder rods of the two pressurized cylinders 4, 5 connect with a compression roller 3 of the beam warper; the vent port of the electromagnetic valve 2 is connected to the admitting ports of the two pressurized cylinders 4, 5. The utility model is characterized in that a quick delivery valve 6 is connected between the vent port of the electromagnetic valve 2 and the admitting ports of the exhaust cavities of the two pressurized cylinders 4, 5 when the compression roller rebound. When the compression roller rebounds, the quick delivery valve reduces the air pressure of the cylinder exhaust cavity to zero in the quickest speed (synchronously the admitting ports enter air), then the compression roller rebounds rapidly to break away from a back beam, thus avoiding rubbing the yarn on account of no rebound of the compression roller or extremely slow rebound of the compression roller as the brake is put on. When the pressurized cylinders are in the normal compression state, the pressurizing process is not influenced owing to the inlet pressure closes the vent of the quick delivery valve.
Description
Technical field:
The utility model relates to a kind of beam warper.Particularly relate to a kind of beam warper run-in index pressue device that has fast-discharge valve.Belong to technical field of textile machine.
Background technology:
At present, initiatively in the run-in index pressue device of the beam warper of transmission, the problem that more often runs into is through axle: pressure roller does not have resilience or rebound too causes the mill yarn slowly during brake, and this warping at fine-count yarn causes certain negative effect in producing.
In fact pressure roller brake springback process realizes by the conversion that adds air cylinder inlet and outlet chamber that this can be switched by electromagnetic valve realizes.Yet real pressure roller resilience is after pressurization cylinder intake chamber and discharge chamber air pressure balance, inlet chamber air pressure is greater than what begin after the discharge chamber air pressure, and the exhaust velocity of apparent discharge chamber and the intake velocity of inlet chamber are to the speed decisive role of pressure roller resilience.The intake velocity that improves inlet chamber can be by reducing vapour lock or strengthen air inlet air pressure and realize, but should belong to secondary cause with occasion.And the exhaust velocity that improves pressurization inblock cylinder air cavity is to use the principal element of occasion.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of beam warper run-in index pressue device that has fast-discharge valve that can improve pressurization inblock cylinder air cavity exhaust velocity is provided.
The purpose of this utility model is achieved in that a kind of beam warper run-in index pressue device that has fast-discharge valve, comprise that two add air cylinder, electromagnetic valve and connect gas circuit, two piston rods that add air cylinder link to each other with the pressure roller of beam warper, the gas outlet of electromagnetic valve is connected to two air inlets that add air cylinder, is characterized in being connected with fast-discharge valve between the air inlet of pressurization inblock cylinder air cavity when the gas outlet of electromagnetic valve and pressure roller resilience.
During the pressure roller resilience, fast-discharge valve makes inblock cylinder air cavity air pressure reduce to zero (air inlet air inlet simultaneously) with prestissimo, can make to add air cylinder and move rapidly, the pressure roller rapid resilience of device on the pressurization cylinder piston rod breaks away from through axle, and pressure roller does not have resilience or rebound too causes the mill yarn slowly when avoiding braking.When adding air cylinder and be in normal pressurization because admission pressure makes the fast-discharge valve exhaust close so pressure process is not impacted.This device realizes the brake springback process rapidly by getting involved fast-discharge valve, makes the phenomenon of parallel pressurization beam warper brake mill yarn be able to basic solution.
Description of drawings:
Fig. 1 is control principle figure of the present utility model.
The specific embodiment:
As Fig. 1, the utility model is a kind of beam warper run-in index pressue device that has fast-discharge valve.Mainly adding air cylinder 4,5, electromagnetic valve 2, accurate proportioning valve (or manual pressure regulating valve) 1, fast-discharge valve 6 and connection gas circuit etc. by pressure roller 3, two forms.The air inlet of electromagnetic valve 2 is inserted in the gas outlet of accurate proportioning valve or manual pressure regulating valve 1, two piston rods that add air cylinder 4,5 link to each other with pressure roller 3, the gas outlet of electromagnetic valve 2 is connected to two air inlets that add air cylinder 4,5, directly or by gas circuit is connected fast-discharge valve 6 between the discharge chamber that adds air cylinder 4,5 during with the pressure roller resilience of the gas outlet of electromagnetic valve 2.The gas outlet on-line equipment of fast-discharge valve 6 adds air cylinder 4,5 in two, or by gas circuit with add air cylinder 4,5 and link to each other, the air inlet of fast-discharge valve 6 then with control electromagnetic valve 2 by gas circuit or directly link to each other.
