Description
Technical field
The present invention relates to a kind of injecting glue syringe needle switch valve, be particularly suited for the injecting glue syringe needle switch valve of glue filling device, belong to technical field of mechanical equipment.
Background technology
The injecting glue needle head structure of the glue injection equipment used at present is the most as shown in Figure 1,, and go out plastic pin 3 and be installed on glue injecting head installing plate 1 by injecting glue needle holder 2, controlled valve is not set between three, lack the control going out plastic pin 3 during injecting glue, so this traditional injecting glue also exists following two subject matter, one, after glue stock preparation system moulding stops, residual is had owing to going out in plastic pin 3, plastic emitting will not be stopped immediately at syringe needle, can produce and drip glue phenomenon, thus affect the quality of injecting glue, reduce work efficiency.
Summary of the invention
The defect existed in view of above-mentioned prior art, the purpose of the present invention is to propose to a kind of controlled injecting glue syringe needle switch valve.
The purpose of the present invention, will be achieved by the following technical programs:
A kind of injecting glue syringe needle switch valve, the closed-system including valve housing and being positioned at valve housing and reset system；It is provided with passage on described valve housing, described closed-system includes the flexible pipe for being sheathed on injecting glue needle tubing, the movable valve core being relatively placed in flexible pipe both sides and is arranged at the spool diaphragm outside spool, described spool diaphragm is perpendicular with passage, described passage is ventilated, band movable valve plug diaphragm promotes spool to make extruding flexible pipe action, described reset system is made up of for the flexible member resetted be arranged on valve core inside, and during described spring element returns, band movable valve plug does adverse movement when extruding.
Preferably, described passage axial symmetry is arranged at valve housing both sides, and the passage of described valve housing side is at least provided with one.
Preferably, offering draw-in groove in described spool, described flexible member is placed in draw-in groove, described draw-in groove and the orthogonal setting of flexible pipe, and flexible member one end abuts the bottom land of spool draw-in groove, and the other end abuts tube wall outside flexible pipe.
Preferably, described flexible pipe is silica gel tube, and described flexible member is spring.
The present invention highlights effect: during can effectively realizing injecting glue by this device control the accurate of injecting glue syringe needle, avoid the glue phenomenon that cannot stop immediately in conventional production process easily occurring in injecting glue and vacuumizing, while improving the quality of injecting glue, also substantially increase the production efficiency of enterprise.
Hereinafter accompanying drawing the most in conjunction with the embodiments, is described in further detail the detailed description of the invention of the present invention, so that technical solution of the present invention is more readily understood, grasps.
Accompanying drawing explanation
Fig. 1 is existing injecting glue needle head structure schematic diagram.
Fig. 2 is the structural representation of this device.
Fig. 3 is the A-A profile of this device.
Detailed description of the invention
Present invention is disclosed a kind of injecting glue syringe needle switch valve, for controlling the plastic emitting of injecting glue syringe needle, shown in Fig. 2, Fig. 3, described injecting glue syringe needle switch valve 11 is arranged in injecting glue needle holder, including valve housing, the closed-system of valve internal and reset system.
Being provided with passage 3 on described valve housing 1, described closed-system includes the flexible pipe 4 for being sheathed on injecting glue needle tubing, the movable valve core 2 being relatively placed in flexible pipe 4 both sides and is arranged at the spool diaphragm 6 outside spool 2.Described flexible pipe 4 is silica gel tube, and described spool diaphragm 6 is perpendicular with passage 3, and when ventilating described passage 3, spool diaphragm 6 is promoted, thus band movable valve plug 2 is made to extrude flexible pipe action at flexible pipe 4.
Described reset system is made up of for the flexible member 5 resetted be arranged on valve core inside, promotes spool 2 to do adverse movement when extruding when described flexible member 5 resets.Described flexible member 5 is spring or other return units.Concrete, offering draw-in groove (not illustrating in figure) in described spool 2, described flexible member 5 is placed in draw-in groove, described draw-in groove and the orthogonal setting of flexible pipe 4, and flexible member 5 one end abuts the bottom land of spool draw-in groove, and the other end abuts tube wall outside flexible pipe 4.
Described passage 3 axial symmetry is arranged at the both sides of valve housing 1, and the passage 3 of described valve housing 1 side is at least provided with one.As the presently preferred embodiments, the passage 3 of the present invention is provided with two in the side of valve housing 1.
The operation principle of the present invention described briefly below:
When glue injection equipment completes injecting glue, when needing to stop the continuation plastic emitting of injecting glue syringe needle, external equipment, by pressure of internally ventilating the passage 3 of shell both sides, causes inner spool diaphragm 6 internally to promote spool 2, and the spool 2 of both sides inwardly promotes extruding flexible pipe 4.Owing to current injecting glue pin the most all uses the softer materials such as rubber, by the extruding of outside flexible pipe 4 so that injecting glue needle tubing temporary closure, thus realize the Guan Bi of injecting glue syringe needle, stop plastic emitting.And when needing the plastic emitting recovering injecting glue needle tubing, have only to stop the external equipment pressure to device air inlet, the spring of valve internal resets, by spool and spool diaphragm top to original position, so that the injecting glue needle tubing of inside replys the state connected, thus realize the unlatching of injecting glue syringe needle, again plastic emitting.
The quantity of breaker in middle valve of the present invention can increase and decrease according to the quantity of injecting glue needle tubing.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes of being formed, within all falling within protection scope of the present invention.
