The specific embodiment
The utility model has disclosed a kind of piston-type measurement glue-injection machine, as shown in the figure, roughly is made up of driver 1, drive block 2, piston rod 4, piston bush 5, baffle 7 and injecting glue needle tubing 9 from top to bottom.
Described drive block 2 is connected with driver 1, and is moved back and forth by this driver 1 control.In the present embodiment, driver 1 is a stepper motor, and is connected for screw rod between the described drive block 2.Described drive block 2 is provided with one and is used for the whether sensor 3 of butt of induction piston bar 4 and drive block 2, and this sensor 3 can be near inductive switch or pressure inductor.The concrete application of described sensor 3 is detailed later.
The below of drive block 2 is provided with piston bush 5, and the piston rod 4 and the piston 6 that interfix, also can move back and forth in this piston bush 5.Described piston rod 4 can drive block 2 butts, and described piston 6 is divided into lubricant reservoir 51 and glue chamber 52 with the inner chamber of described piston bush 5.Contain lubricating oil in the described lubricant reservoir 51, contain glue to be injected in the described glue chamber 52.
The below of described piston bush 5 is provided with a baffle 7, is provided with feed pipe 71 and discharge nozzle 73 in the described baffle 7.Described glue chamber 52 is connected with a glue compression system 10 by feed pipe 71, and described feed pipe 71 is provided with the charging switch 72 that control glue flows.Described glue chamber 52 also with between the injecting glue needle tubing 9 is connected by discharge nozzle 73, and described discharge nozzle 73 is provided with the discharging switch 74 that control glue flows.Because present embodiment is the dual liquid type glue-injection machine, therefore the glue that flows out through discharge nozzle 73 also needs to inject away from injecting glue needle tubing 9 at last through entering into described injecting glue needle tubing 9 behind the blender 8 again.
Described glue compression system 10, driver 1, sensor 3, charging switch 72, discharging switch 74 all by a controller 11 controls, for simply being electrically connected, do not repeat them here between described controller 11 and the above-mentioned device.
Introduce the course of work of this preferred embodiment below.
Before operate as normal, have abundant evacuation procedure in the glue chamber 52, guarantee to be full of glue in advance in the cavity, the volume in glue chamber 52 maximization at this moment abuts on the described drive block 2 piston rod 4.Then, controller 11 begins to control driver 1 and starts, and driver 1 orders about drive block 2 and moves down, and drives piston rod 4 and moves down.Because driver 1 is stepper motor, can calculates gel quantity in conjunction with the area of piston bush, thereby can gel quantity as required draw the displacement of drive block 2 and piston rod 4.Piston rod 4 presses down the glue that can make in the glue chamber 52 and is forced out, and this moment, controller 11 control charging switches 72 cut out, and discharging switch 74 is opened, and glue will be injected by blender 8 and injecting glue needle tubing 9 backs.
When drive block 2 and piston rod 4 move down into extreme position (this extreme position is by driver 1 control), controller 11 can produce following action: control driver 1 makes it to control to move on the drive block 2 and resets, and opens charging switch 72, closes discharging switch 74.Because the pressure of glue compression system 10 is than the pressure height in glue chamber 52, therefore, glue can enter into glue chamber 52 by feed pipe 71, fills glue promptly for described glue chamber 52, piston 6 promptly can be promoted by the pressure of glue to move, and drives simultaneously on the piston rod 4 and moves.
When moving on the piston rod 4 when touching described drive block 2, described inductor 3 is just sensed described piston rod 4 and has been put in place, this inductor 3 can transmit signal and give described controller 11,11 of this controllers can cut out charging switch 72, and open discharging switch 74, and then driving driver 10 carries out the injecting glue second time.Reciprocal successively, just can ceaselessly inject glue.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
