Description

Two liquid type mixing and glue injection devices

Technical field

The utility model relates to a kind of glue filling device, particularly relates to a kind of two liquid type mixing and glue injection devices that utilize Numerical Control (NC) to drive mobile route.

Background technology

Referring to shown in Figure 1, generally need make waterproof, the article 1 of airtight or pooling feature (car light for example, lampshade, windowsill, water filter ... or the like), usually an adhesive tape 2 can be sticked along the profile of article 1, because the shape of each article 1 differs, if article 1 itself have complex contoured shape, the producer usually can be with the adhesive tape 2 cutting section of becoming material in advance, a section ground bending connects and sticks on article 1 again, so just finish manufacturing of complicated shape adhesive tape 2, though utilize the above-mentioned means really can be on article 1 with adhesive tape 2 gluings, yet in the use still some problem need to be resolved hurrily, first, if adhesive tape 2 is pasted on article 1 through after cutting again, have the space unavoidably 2 of two adhesive tape and produce, have a strong impact on the water proofing property and the air-tightness of adhesive tape 2; Can form the contact 3 of overshooting shape when the second, two adhesive tape 2 are joined, have a strong impact on the aesthetic appearance of adhesive tape 2.

The dealer has developed a kind of injecting glue machinery at present, its inside has charging aperture and mixing chamber, after sizing material fills part mixing by charging aperture arrival mixing chamber, just but extrusion molding goes out an adhesive tape, yet the charging aperture of general injecting glue machinery is quite far away apart from the path of mixing chamber, and runner is to be bending, the dead angle is numerous hoards residual sizing material quite easily, sizing material is by long runner the time, easily crystallization hardening and be unfavorable for cleaning, if when changing the sizing material of different colours, new sizing material mixes with old sizing material in the runner easily and produces the color aberration, no matter be maintenance or keep in repair all suitable bother and time-consuming.

The utility model content

The utility model purpose is to provide a kind of easy two liquid type mixing and glue injection devices of dynamic injecting glue contactless, not residual buildup and maintenance that reach.

The utility model provides a kind of two liquid type mixing and glue injection devices, include a gun body, a mixing head unit, a driver element and a control module, it is characterized in that: gun body has two roads and is located at charging aperture and two roads that gun body dual-side place can supply A, B two liquid to enter and directly is located at the runner that the gun body lower end is connected with two charging apertures; The mixing head unit have shoot material pipe and who is set in the gun body lower end be set in that the pipe that shoots material is inner can be to the screw rod of the push-jump extrusion of sizing material high speed, the pipe that shoots material is provided with one at upper end and is communicated with the mixing chamber that can supply A, B two liquid to be mixed into sizing material with runner; Driver element has one group of motor and one group and stretches and be located at gun body inside and can make up for the join axle of interlock running of motor and screw rod; Control module has one group of piston in combination, two and buries the valve pocket that is fixed in the gun body charging aperture and two groups and piston in combination underground and join and can the valve that valve pocket be made on-off action be made up.

Effect of the present utility model is to utilize outside Numerical Control (NC) to drive to shoot material the pipe mobile route with the adhesive tape of extrusion complicated shape dynamically, and is difficult for buildup and maintenance is easy to advantage by the distance that shortens two runners to reach.
