Description
Technical field
The utility model relates to a kind of injecting glue syringe needle switch valve, is particularly useful for the injecting glue syringe needle switch valve of glue filling device, belongs to technical field of mechanical equipment.
Background technology
The injecting glue needle head structure of the glue injection equipment used at present all as shown in Figure 1,, with go out plastic pin 3 and be installed on glue injecting head installing plate 1 by injecting glue needle holder 2, between three, controlled valve is not set, the control to going out plastic pin 3 is lacked in the process of injecting glue, so this traditional injecting glue also exists following two kinds of subject matters, one, after system moulding stopping got the raw materials ready by glue, due to go out have in plastic pin 3 residual, syringe needle place can not stop plastic emitting immediately, can produce and drip glue phenomenon, thus affect the quality of injecting glue, reduce operating efficiency.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes a kind of controlled injecting glue syringe needle switch valve.
The purpose of this utility model, will be achieved by the following technical programs:
A kind of injecting glue syringe needle switch valve, comprises valve housing and is positioned at closed-system and the resetting system of valve housing; Described valve housing is provided with passage, described closed-system comprises for being sheathed on the flexible pipe on injecting glue needle tubing, the movable valve core being relatively placed in flexible pipe both sides and the spool diaphragm be arranged at outside spool, described spool diaphragm and passage perpendicular, described passage is ventilated, band movable valve plug diaphragm promotes spool and does the action of extruding flexible pipe, described resetting system, by being arranged on forming for the flexible member resetted of valve core inside, is with movable valve plug to do counter motion to during extruding during described spring element returns.
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, offer 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 silicone tube, and described flexible member is spring.
The utility model gives prominence to effect: effectively can realize the precise hard_drawn tuhes to injecting glue syringe needle in injecting glue process by this device, avoid in production process in the past cannot stop immediately very easily occurring in injecting glue and vacuumizing drip glue phenomenon, while improving the quality of injecting glue, also substantially increase the production efficiency of enterprise.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.

Detailed description of the invention
The utility model discloses a kind of injecting glue syringe needle switch valve, for controlling the plastic emitting of injecting glue syringe needle, shown in composition graphs 2, Fig. 3, described injecting glue syringe needle switch valve 11 is arranged in injecting glue needle holder, comprises valve housing, the closed-system of valve internal and resetting system.
Described valve housing 1 is provided with passage 3, and described closed-system comprises for being sheathed on the flexible pipe 4 on injecting glue needle tubing, the movable valve core 2 being relatively placed in flexible pipe 4 both sides and the spool diaphragm 6 be arranged at outside spool 2.Described flexible pipe 4 is silicone tube, and described spool diaphragm 6 is perpendicular with passage 3, and when ventilating to described passage 3, spool diaphragm 6 is pushed, thus band movable valve plug 2 does the action of extruding flexible pipe to flexible pipe 4 place.
Described resetting system, by being arranged on forming for the flexible member 5 resetted of valve core inside, promotes spool 2 and does counter motion to during extruding when described flexible member 5 resets.Described flexible member 5 is spring or other return units.Concrete, offer draw-in groove (meaning not shown in the figures) 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 preferred embodiment, passage 3 of the present utility model is provided with two in the side of valve housing 1.
Below sketch operation principle of the present utility model:
When glue injection equipment completes injecting glue, when needing to stop injecting glue syringe needle to continue plastic emitting, external equipment is exerted pressure by internally ventilating to 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.What generally all adopt due to current injecting glue pin is the material that rubber etc. is softer, by the extruding of outside flexible pipe 4, makes injecting glue needle tubing temporary closure, thus realizes the closed of injecting glue syringe needle, stop plastic emitting.And when needing the plastic emitting recovering injecting glue needle tubing, only need to stop external equipment exerting pressure to device air inlet, the spring of valve internal resets, by spool and spool diaphragm top to original position, thus make inner injecting glue needle tubing reply the state connected, thus realize the unlatching of injecting glue syringe needle, plastic emitting again.
The quantity of the utility model breaker in middle valve can increase and decrease according to the quantity of injecting glue needle tubing.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
