Description
Technical field
The utility model relates to the ribbon glue spreading apparatus, is specifically related to a kind of reduction valve that is used for the ribbon glue spreading apparatus.
Background technique
In the prior art, a kind of device that is used for coating on the ribbon surface silica gel is arranged, for making glue spreading apparatus when the gluing, can carry out gluing more uniformly on the ribbon surface, must control out the pressure in sizing material hole, make the pressure of glue discharging opening remain unanimity, could guarantee that gluing is even, quality of product is guaranteed; Because the viscosity of this glue is big, and general fluid pressure valve can not use on this equipment, if adopt the automatic controller of other electronic type to control the pressure of glue discharging opening, apparatus structure complexity has then increased the cost of equipment.
The model utility content
The purpose of this utility model is, a kind of reduction valve that is used on the spreader is provided, and this reduction valve simple in structure can adjust the pressure in sizing material hole automatically.
The technological scheme that the utility model provides is as follows: construct a kind of reduction valve, comprise a valve body, valve body has a step hole, be provided with a spool in the macropore of step hole, spool has a valve rod that stretches out downwards, the bottom of valve body is a cavity coaxial with described step hole, be provided with a bearing in the cavity, the top of bearing is provided with a baffle plate, baffle plate has one for the flexible up and down hole of described valve rod, in bearing, be provided with a steel ball that is resisted against described valve rod end, the bottom of steel ball and a return spring lean, and the other end of return spring is resisted against on the support that is connected with the valve body bottom, has at least one glue-feeder on the sidewall of described cavity, on the sidewall of described bearing, have the hole that at least one flows to for colloid, on the sidewall of the small diameter bore of described step hole, have at least one glue discharging opening, also be connected with a bearing, be provided with a screw in the bearing on described valve body top, be provided with a pressure adjusting nut in the screw, between described nut and described spool, be provided with a pressure regulating spring.
The utlity model has following advantage: full-bodied sizing material enters the cavity from glue-feeder, this moment, valve rod stretched out outside baffle holes, steel ball is in state of suspension, sizing material can flow out from baffle holes, deliver to the gluing head by the glue discharging opening, when the pressure of glue discharging opening reaches pressure set points, can set by adjusting nut, be that pressure is when being higher than pressure regulating spring, spool moves up under the effect of high pressure, progressively raises, steel ball moves up under the effect of return spring, and seal baffle holes, sizing material is no longer sent, when the pressure of glue discharging opening is lower than the pressure of glue-feeder, spool is under the effect of pressure regulating spring, move down, promote steel ball and leave baffle holes, sizing material passes through from baffle holes, the glue discharging opening begins to send sizing material, thereby realizes regulating automatically the purpose of glue discharging opening pressure.
