The specific embodiment
Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the application can mutually combine, and below in conjunction with the drawings and specific embodiments, the utility model are described in further detail.
As extremely shown in Figure 5 in Fig. 1; This practical new described Multi needle glue dispensing valve; Include valve body 1; Be provided with dispensing needle head 2 and at least 2 piston 3 Fig. 4 more than at least 2 on described valve body 1; The spool 5 that is provided with valve pocket 4 in described valve body 1 and is complementary with valve pocket 4; The glue injection channel that the past piston glue of formation chamber 6 interior injecting glues are used; After changing valve pocket 4 and spool 5 relative positions; Be configured for being communicated with respectively the some glue passage of each dispensing needle head 2; Also be provided with branching block 71 time at valve body; Be provided with several tap holes 8 on branching block 7; Described dispensing needle head 2 is arranged on branching block 7 bottoms by syringe needle connector 17.So, compare with traditional glue dispensing valve, glue dispensing valve described in the utility model has a plurality of dispensing needle heads 2, in the situation that point glue equipment is equally only installed a glue dispensing valve, in identical installing space, syringe needle quantity can be multiplied, and production capacity also is multiplied naturally, and volume and weight increase seldom.
On the basis of technique scheme, as shown in Figure 1, be provided with 2 pistons 3 on described valve body 1, described piston 3 is complementary with a dispensing needle head 2 respectively.So, in identical installing space, syringe needle quantity can be installed two, and production capacity is also two times of single needle glue dispensing valve naturally, and volume and weight increase seldom.
As shown in Figure 3, described valve pocket 4 and be circle with spool 5 that valve pocket 4 is complementary, valve pocket 4 changes the connected state of passage with spool 5 by rotation.And in another embodiment, described valve pocket 4 and be square with spool 5 that valve pocket 4 is complementary, valve pocket 4 changes the connected state of passage with spool 5 by translation.
As shown in Figure 6, described branching block 7 only has one.The branching block 7 that need only change dimension when like this, making the workpiece of different size gets final product.And as shown in Figure 7, described branching block 7 is comprised of the piecemeal of a plurality of positions that relatively move.Like this, can adjust as required the position of branching block, the position that reaches point of adjustment needle head 2 adapts itself and workpiece size.On the basis of technique scheme, the position dimension of 7 times mounting points needle heads 2 of described branching block changes because workpiece is different.
As shown in Figure 6, be provided with 8 above dispensing needle heads 2 and the piston 3 corresponding with it more than 8 on described valve body 1.So, in identical installing space, syringe needle quantity can increase manyfold, and production capacity also increases manyfold naturally, and volume and weight increase seldom.
On the basis of technique scheme, as Fig. 8 and shown in Figure 9, the dispensing needle head 2 of described Multi needle glue dispensing valve is arranged in a row, each piston 3 of described Multi needle glue dispensing valve can each be had independent driving mechanism by oneself, when not needing wherein certain several dispensing needle head 2 work, need only close corresponding driving mechanism and get final product, its use is more flexible, accommodation is wider thereby make.
On the basis of technique scheme, as shown in figure 10, described branching block 7 is made of one with valve body 1.
Further be elaborated as an example of the double needle glue dispensing valve example.
To shown in Figure 5, glue dispensing valve comprises valve body 1, packing element connector 10, briquetting 11, cover plate 12, bolt 13, the first sealing ring 141, the second sealing ring 142, the 3rd sealing ring 143, the 4th sealing ring 144, the 5th sealing ring 145, valve pocket 4 and spool 5, a plurality of piston 3 and piston locking member 15, a plurality of piston connector 16, a plurality of syringe needle connector 17 and syringe needle 2 etc. as Fig. 2.
Be provided with installing hole, the valve pocket installing hole of packing element connector 10, a plurality of piston glue chambeies, a plurality of glue channel hole etc. in valve body 1.
The valve pocket 4 of glue dispensing valve is arranged on 1 li of the valve body of glue dispensing valve, and spool 5 can be in the interior rotation of valve pocket 4, and spool 5 can not form different states simultaneously from the relative angular position of valve pocket 4.
Piston 3 can slide in the piston glue chamber of valve body 1, thereby changes the volume size in glue chamber.
The effect of branching block 7 be the glue that will extrude from B and C respectively water conservancy diversion to D and E.Position or quantity according to the installing hole of the tap hole 8 on branching block 7 and syringe needle connector 17 are different, branching block 7 can be divided into plurality of specifications, the workpiece of corresponding different size, can realize like this in the situation that do not change valve body 1 as long as change the workpiece that branching block 7 can be done different size respectively.Simultaneously due to branching block 7 having been arranged, tap hole 8 easily process, can not produce passage dead angle, easy cleaning tap hole 8 in the practice process when processing tap hole.
Sealing ring plays sealing function, and wherein the first sealing ring 141 is necessary, and the sealing that lacks the first sealing ring 141 can't guarantee the plastic squeeze amount; The second sealing ring 142 is used for sealing syringe needle connector upper end; The 3rd sealing ring 143 and the 4th sealing ring 144 are used for sealing tap hole 8 and the guiding gutter on branching block 7; The 5th sealing ring 145 is non-essential, and Main Function is that the glue that prevents seepage flows out the valve body glue dispensing valve of making dirty outward.
The pattern of piston locking member 15 and piston connector 16 is not limited to the pattern shown in figure.
Its specific works principle is as follows:
Be illustrated in figure 4 as the injecting glue state of glue dispensing valve, this moment, spool 5 was communicated with B and C with A, and D is disconnected with E and is connected, and when piston 3 moves from the bottom up, the volume in piston glue chamber 6 can increase, and glue can enter B and C place from A.
Be illustrated in figure 5 as the plastic squeeze state of glue dispensing valve, this moment spool 5 with B be communicated with D, C is communicated with E, A is disconnected connection, and disconnect between B and C, when piston 3 moves from top to bottom, the volume in piston glue chamber 6 can reduce, glue just is extruded into D place's outflow from B, is extruded into E place's outflow from C.The displacement of piston 3 each motions can be set, and is not that glue of every notes just can only squeeze glue one time, but can squeezes repeatedly, is a glue.
Need to carry out the exhaust bubble when injecting glue first, purpose is to allow only have glue in piston glue chamber 6 and there is no an air, and method is for carrying out repeatedly injecting glue and plastic squeeze, at this moment plastic squeeze stroke range.Do not have air as long as only have glue in piston glue chamber 6, so from theory, how many volumes in piston glue chamber 6 reduces, and just has how much glue to extrude from syringe needle, thereby realizes volume measurement formula point glue.When the displacement size of, motion identical when the diameter of two pistons 3 is also identical, is also identical from two syringe needles glue amount out at every turn.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that do not break away from principle of the present utility model and spirit can be carried out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalency range thereof.
