The gun nozzle is provided with a glue outlet control needle valve, the needle tubing is provided with a glue inlet pipe which is communicated with the glue-storing cavity, and the glue inlet pipe is provided with a glue inlet control needle valve. The rationed glue-injecting gun uses the principle and structure of an injector for reference, and achieves stable and high-precision glue quantity control by releasing a certain glue quantity.
Description
Technical field
The utility model relates to colloid-injecting gun, especially the colloid-injecting gun of needle valve.
Background technology
Traditional colloid-injecting gun all is needle valve, and as shown in Figure 1, it generally comprises entry needle 1, glass needle tubing 2, piston 3 and push rod 4, mainly is that binding time and pressure are controlled gel quantity again for opening and closing by needle-valve.The factor that affects gel quantity has the control accuracy of the response time of needle-valve, time, the control accuracy of pressure, the viscosity of glue etc.And the viscosity of glue is relevant with temperature, humidity etc., thereby the variation of viscosity can affect the flow velocity of glue affects gel quantity, this shows, traditional colloid-injecting gun is difficult to realize the precision control of glue amount.The injecting glue accuracy of measurement is inadequate during injecting glue, affects easily production efficiency, also can waste a large amount of glue.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of quantitative glue injection rifle, can accomplish quantitative sealant yielding, is conducive to enhance productivity, and saves glue quantity.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of quantitative glue injection rifle, comprise needle tubing, be located at the piston in the described needle tubing, the push rod that is connected with described piston, described needle tubing front end is provided with the rifle mouth that is connected with entry needle, form glue storage cavity between described piston and the needle tubing, described rifle mouth is communicated with glue storage cavity; Described rifle mouth is provided with plastic emitting control needle-valve, and described needle tubing is provided with the glue inlet tube that is communicated with glue storage cavity, and described glue inlet tube is provided with into glue control needle-valve.The principle of quantitative glue injection rifle: behind the full glue of glue storage cavity storage in the needle tubing, open plastic emitting control needle-valve, close simultaneously the additional glue that advances of glue and control needle-valve; Promoting push rod according to the gel quantity of setting discharges the glue of certain volume in the glue storage cavity by piston through the rifle mouth; After finishing plastic emitting, close plastic emitting control needle-valve, that opens simultaneously that glue replenishes advances glue control battle array needle-valve, and outside storage glue tank replenishes back glue storage cavity with the glue of disappearance through glue inlet tube, makes glue storage cavity again fill up glue.The utility model is realized control stable, high accuracy glue amount by the discharge of constant volume glue.Because be constant volume control, the precision of gel quantity just only depends on the control of piston mobile accuracy.
As improvement, described plastic emitting control needle-valve advances glue control needle-valve and links with described.Guarantee plastic emitting action and the independence of advancing the glue action.
As improvement, described rifle mouth is " Z " shape, makes the space that plastic emitting control needle-valve is installed more, implements more convenient.
As improvement, described glue inlet tube is connected with the storage glue tank of pressurization.When adding glue, utilize the pressure in the storage glue tank that glue is pressed in the glue storage cavity of needle tubing.
As improvement, described push rod is connected with stepper motor or servomotor.Because be constant volume control, the precision of gel quantity just only depends on the control of piston mobile accuracy, utilize stepper motor or servomotor control push rod, make the mobile accuracy of push rod higher.
The beneficial effect that the utility model compared with prior art brings is:
The utility model is used for reference principle and the structure of syringe, by the discharge of constant volume glue, realizes control stable, high accuracy glue amount; Utilize stepper motor or servomotor control push rod, make the mobile accuracy of push rod higher, owing to be constant volume control, the precision of gel quantity just only depends on the control of piston mobile accuracy, therefore can realize the precision of gel quantity.
Description of drawings
Fig. 1 is the prior art structural representation.
Fig. 2 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 2, a kind of quantitative glue injection rifle comprises needle tubing 12, is located at the piston 11 in the described needle tubing 12, the push rod 13 that is connected with described piston 11.Described needle tubing 12 front ends are provided with the rifle mouth 6 that is connected with entry needle 5, and described rifle mouth 6 is " Z " shape; " Z " shape rifle mouth is formed by connecting by upper lateral tube 61, middle vertical tube 62 and lower transverse tubule 63, and upper lateral tube 61 is connected with needle tubing 12 and is communicated with glue storage cavity 14, and lower transverse tubule 63 is connected with entry needle 5; Vertical tube 62 is provided with plastic emitting control needle-valve 7 in the middle of described; Glue in the glue storage cavity 14 is successively by being extruded behind upper lateral tube 61, middle vertical tube 62, lower transverse tubule 63, the entry needle 5.Form glue storage cavity 14 between described piston 11 and the needle tubing 12, described needle tubing 12 is provided with glue inlet tube 10, and an end of glue inlet tube 10 is communicated with glue storage cavity 14, and the other end is communicated with the storage glue tank 15 that is added with pressure of outside; Described glue inlet tube 10 is provided with into glue control needle-valve 9, and the position of advancing glue control needle-valve 9 is corresponding with the position of plastic emitting control needle-valve 7, the convenient interlock that realizes the two.Described push rod 13 is connected with stepper motor or servomotor, utilizes the displacement of stepper motor or servomotor control push rod 13.
The principle of quantitative glue injection rifle: behind the full glue of needle tubing 12 interior glue storage cavity 14 storages, open plastic emitting control needle-valve 7, close simultaneously the additional glue that advances of glue and control needle-valve 9; Promoting push rod 13 according to the gel quantity of setting discharges the glue of glue storage cavity 14 interior certain volumes by piston 11 through the rifle mouth; After finishing plastic emitting, close plastic emitting control needle-valve 7, that opens simultaneously that glue replenishes advances glue control battle array needle-valve, and outside storage glue tank 15 glue with disappearance replenish back glue storage cavity 14 through glue inlet tube 10, make glue storage cavity 14 again fill up glue.
According to control accuracy, gel quantity is large, all replenishes after the each plastic emitting of needs; Little gel quantity, can N plastic emitting after, replenish a glue, needle-valve just needs self contained function.
Quantitative glue injection rifle of the present utility model is used for reference principle and the structure of syringe, by the discharge of constant volume glue, realizes control stable, high accuracy glue amount.Because be constant volume control, the precision of gel quantity just only depends on the control of piston 11 mobile accuracies.
