Abstract
The invention discloses a switching valve of a glue injection needle. The switching valve comprises a valve shell, a closing system and a reset system, wherein the closing system and the reset system are positioned in the valve shell; ventilating holes are formed in the valve shell; the closing system comprises a flexible pipe sleeving a glue injection needle tube, movable valve cores oppositely arranged at the two sides of the flexible pipe, and valve core diaphragms at the outer sides of the valve cores; the valve core diaphragms are vertical to the ventilating holes; the ventilating holes are ventilated to drive the valve core diaphragms to push the valve cores to extrude the flexible pipe; the reset system consists of elastic elements which are arranged in the valve cores and are used for resetting the valve cores; when the elastic elements are used for resetting the valve cores, the valve cores are driven to do movement reverse to the movement in extrusion. The switching valve disclosed by the invention has the advantages that precise control to the glue injection needle during the glue injection process can be effectively carried out, the phenomena that glue injection cannot be stopped immediately in the original production process and glue dripping is extremely likely to occur in vacuum operation are avoided, the quality of glue injection is improved and the production efficiency of an enterprise is also improved substantially.
Description
Technical field
The present invention relates to a kind of injecting glue syringe needle switch valve, be particularly useful for the injecting glue syringe needle switch valve of glue filling device, belong to plant equipment field.
Background technology
The injecting glue needle head structure of the glue injection equipment using 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, controlled valve is not set between three, in the process of injecting glue, lack the control to going out plastic pin 3, so this traditional injecting glue exists following two kinds of subject matters, one, get the raw materials ready after system moulding stops at glue, due to go out in plastic pin 3, have residual, syringe needle place can not stop plastic emitting immediately, can produce and drip glue phenomenon, thereby 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 object of the invention is to propose a kind of controlled injecting glue syringe needle switch valve.
Object of the present invention, 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; On described valve housing, be provided with passage, described closed-system comprises for being sheathed on flexible pipe on injecting glue needle tubing, being relatively placed in the movable valve core of flexible pipe both sides and being arranged at the spool diaphragm in spool outside, described spool diaphragm and passage are perpendicular, to described passage ventilation, band movable valve plug diaphragm promotes spool and does the action of extruding flexible pipe, described resetting system is made up of the flexible member for resetting that is arranged on valve core inside, does counter motion when described flexible member resets while being with movable valve plug to extruding.
Preferably, described passage axial symmetry is arranged at valve housing both sides, and the passage of described valve housing one side is at least provided with one.
Preferably, in described spool, offer draw-in groove, described flexible member is placed in draw-in groove, the orthogonal setting of described draw-in groove and flexible pipe, the bottom land of flexible member one end butt spool draw-in groove, tube wall outside other end butt flexible pipe.
Preferably, described flexible pipe is silicone tube, and described flexible member is spring.
The outstanding effect of the present invention is: can effectively realize the precision control to injecting glue syringe needle in injecting glue process by this device, that has avoided cannot stopping immediately very easily occurring in injecting glue and vacuumizing in production process in the past drips glue phenomenon, has also greatly improved the production efficiency of enterprise in the quality that has promoted injecting glue.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, so that technical solution of the present invention is easier to understand, grasp.
Brief description of the drawings
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
The present invention has disclosed a kind of injecting glue syringe needle switch valve, and 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, comprises closed-system and the resetting system of valve housing, valve internal.
On described valve housing 1, be provided with passage 3, described closed-system comprises for being sheathed on flexible pipe 4 on injecting glue needle tubing, being relatively placed in the movable valve core 2 of flexible pipe 4 both sides and being arranged at the spool diaphragm 6 in spool 2 outsides.Described flexible pipe 4 is silicone tube, and described spool diaphragm 6 is perpendicular with passage 3, and in the time that described passage 3 is ventilated, spool diaphragm 6 is pushed, thereby band movable valve plug 2 is done the action of extruding flexible pipe to flexible pipe 4 places.
Described resetting system is made up of the flexible member 5 for resetting that is arranged on valve core inside, and described flexible member 5 does counter motion while promoting spool 2 to extruding while reset.Described flexible member 5 is spring or other return units.Concrete, in described spool 2, offering draw-in groove (meaning not shown in the figures), described flexible member 5 is placed in draw-in groove, described draw-in groove and the orthogonal setting of flexible pipe 4, the bottom land of flexible member 5 one end butt spool draw-in grooves, other end butt flexible pipe 4 outside tube walls.
Described passage 3 axial symmetry are arranged at the both sides of valve housing 1, and the passage 3 of described valve housing 1 one sides is at least provided with one.As preferred embodiment, passage 3 of the present invention is provided with two in a side of valve housing 1.
Below sketch operation principle of the present invention:
When glue injection equipment completes injecting glue, need to stop injecting glue syringe needle continuation plastic emitting time, external equipment is exerted pressure to internal ventilation by the passage 3 to shell both sides, causes that inner spool diaphragm 6 promotes spool 2 to inside, and the spool 2 of both sides inwardly promotes extruding flexible pipe 4.What all adopt because current injecting glue pin is general is the softer materials such as rubber, by the extruding of outside flexible pipe 4, injecting glue needle tubing is temporarily sealed, thereby realizes the closure of injecting glue syringe needle, stops plastic emitting.And in the time need to recovering the plastic emitting of 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 extremely original position, spool diaphragm top, thereby make inner injecting glue needle tubing reply the state of connecting, thereby realize the unlatching of injecting glue syringe needle, again plastic emitting.
In the present invention, the quantity of switch valve can increase and decrease according to the quantity of injecting glue needle tubing.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming, within all dropping on protection scope of the present invention.
