Description

Glue-injection machine

The utility model relates to the spray field of high viscosity liquid, the spray machinery of definite a kind of high viscosity jelly of saying so.

At present the spray machine in the society can only the spray low-viscosity (mobile) liquid, and is mainly with the way of smearing, just powerless to spray in some workpiece slits to the processing of using the high viscosity jelly, can only replace with other materials, do not reach ideal effect.

The purpose of this utility model is: design a kind of can be to the machinery of the spray of viscous liquids such as little space spray high viscosity jelly such as slit.

The technical solution of the utility model is: a kind of glue-injection machine is to be made of base, lift cylinder, air motor, injecting glue pump, FE Glue Gun, motor suspension rod, air inlet pipe etc.Its special character is: air motor is by changement and two-way operation cylinder constitute fast automatically, automatically changement is installed in two-way operation cylinder block top fast, collision block moving up and down is equipped with in its center, collision block has central through hole, pull bar is inserted in the collision block through hole, and pass two-way operation cylinder block loam cake, be fixed in the centre bore of piston rod in the cylinder, collision block is contained in and carries in the valve buckle, a valve gap respectively is equipped with on the two sides, front and back of carrying valve buckle, two toggles are installed in both sides, and toggle contact with stage clip end in being installed in spring base, and two spring bases are installed on the housing of automatic quick changement.Air motor is as the power source of injecting glue pump, and open back, compressed air when air motor air inlet ball valve and chew, slide-valve, go up porting and enter cylinder top and promote piston and move downward through air inlet, piston pulling pull bar, drive is hit certainly and is moved down.After collision block is crossed the stage clip center line, under the effect of stage clip, to beat downwards fast, bump carries valve buckle and jumps to the bottom together with carrying valve gap by top, and porting is decontroled on the valve gap at this moment, and is in a row vaporous.Porting is communicated with into air inlet with incoming air conduit under the cylinder, carries out the inflation of piston bottom, and piston begins to move upward.Piston drives pull bar, promoting collision block together upwards moves, when crossing the stage clip center line, collision block jumping on rapidly under the stage clip effect, bump carries valve buckle and jumps to top together with carrying valve gap, this moment, valve gap was open in a row vaporous with porting under the cylinder, last porting is communicated with air inlet pipe to be inflated, and piston begins to move down, and moves back and forth work according to this.Because reversal valve is subjected to the stage clip effect commutation of beating in cylinder piston motion, the used time is very short, promptly reaches quick commutation.Connecting rod is fixedlyed connected with the air motor piston rod on the injecting glue pump, and air motor drives the injecting glue pump work.Promotion lower link and upper piston, lower piston move downward when last connecting rod moves downward, valve on the lower piston is pushed open by the material of bottom, material enters into lower piston top, after the air motor commutation, lower piston moves upward, valve enters in the upper piston tube in the material warp on lower piston top, and is full of the upper piston tube.When reversing piston moves down again, middle valve closing, the valve on the upper piston is washed open, and material enters the top of upper piston, and the material of lower piston bottom enters lower piston tube top by the valve on the lower piston again simultaneously.After the commutation, move on the piston, the material on upper piston top is received in material storing room, can spray from discharging opening after being full of again.

Because of the volume of last connecting rod accounts for half of upper piston tube volume, so the material in the tube is by behind the valve when upper piston moves down, half can fill up the upper piston tube, half is squeezed into material storing room, and from the discharging opening ejection, after the commutation, in the upper piston tube institute surplus half be drawn into material storing room, and spray from discharging opening.

Owing to adopt technique scheme, can realize that a kind of commutating speed is fast, the spray machinery of the high pressure adhesive of continuous injection.

Below in conjunction with accompanying drawing embodiment, further specify.
