Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
The utility model is as Figure 1-Figure 2, including flow distribution plate 1, is equipped with hot flow path 11, the heat in the flow distribution plate 1
Sizing material full of flowing in runner 11, one end of the hot flow path 11 are equipped with the plunger 12 for closing the hot flow path 11, institute
It states flow distribution plate 1 and is equipped with the needle mouth 13 communicated with the hot flow path 11；Needle 2 passes through needle mouth 13 and is threaded through the hot flow path
In 11；Positioning sleeve 3 is equipped between the needle 2 and needle mouth 13；Directly plunger 12 and needle 2 are separated by positioning sleeve 3, filled out
The gap between positioning sleeve 3 and plunger 12 (2 back side of needle) has been filled, so that sizing material is directly contacted with positioning sleeve 3, has passed through positioning sleeve
3 guide functions avoid the occurrence of 2 back side sizing material of needle so that sizing material be prevented to reside in the back side of needle 2 in flow process
Jaundice will be led to the problem of in product surface when causing jaundice to black because the residence time is too long, and being brought out to black, make to produce
The phenomenon that product are scrapped.
As shown in figure 3, the positioning sleeve 3 includes columned ontology 31, the ontology 31 is equipped with needle in the axial direction
The outer wall in channel 32, the ontology 31 is equipped with positioning table 33, and the positioning table 33 is fastened on the locating slot 14 of the flow distribution plate 1
On；The lower part of the ontology 31 is contacted with the inner wall of the hot flow path 11, and the lower part of the ontology 31 is along the hot flow path 11
Axis direction is equipped with gap 34, and the gap 34 is set to the ontology 31 towards on the outer wall of the sizing material flow direction.Installation
When positioning table 33 is placed on locating slot 14, very efficiently positioning sleeve 3 can be installed in place, when in use, sizing material is in warm
It flows, is flowed into positioning sleeve 3 via the gap 34 on positioning sleeve 3, and due to the barrier effect of 3 side wall of positioning sleeve in runner 11,
Positioning sleeve 3 is lengthened to be cooperated with hot flow path 11, allows sizing material to pass through in the 2 open and clear mouth 34 in front of needle, at 2 back side of needle and positioning sleeve 3
Cooperate with needle 2, make this region not intrinsic energy glue, avoid the occurrence of 2 back side sizing material of needle causes jaundice to be sent out because the residence time is too long
It is black, and the phenomenon that jaundice will be led to the problem of in product surface when being brought out and blacked, make scrap of the product.
Along 11 axis direction of hot flow path, the inner wall of the hot flow path 11 is divided into upper side wall 111 and lower wall 112, institute
Upper side wall 111 is stated equipped with needle mouth 13, the ontology 31 passes through lower end surface and the institute of the needle mouth 13 and the ontology 31
State the contact of lower wall 112.That is, entire hot flow path 11 is truncated the ontology 31 of positioning sleeve 3, and sizing material only can be from calmly
Enter in positioning sleeve 3 at the gap 34 opened up on the ontology 31 of position set 3, in this way, needle 2 only cooperates with positioning sleeve 3, due to positioning
The blocking of set 3, there is no sizing materials at needle 2 back side, so that avoid the occurrence of 2 back side sizing material of needle causes to send out because the residence time is too long
Huang blacks, and the phenomenon that will lead to the problem of jaundice nigrescence in product surface when being brought out, make scrap of the product.
Upper channel, middle channel and the lower channel that needle channel 32 is divided to be sequentially communicated, the upper channel and lower channel with
There is gap between the needle 2, the middle channel is bonded closely with the needle 2, so in use, 31 energy of ontology
It is enough to stop sizing material to flow between plunger 12 and needle 2 completely, and since middle channel and needle 2 fit closely, also reduce needle 2 and
The resident amount of sizing material between middle channel, and 3 disassembling cleaning of positioning sleeve, even if there is a small amount of sizing material to reside in positioning sleeve 3,
Positioning sleeve 3 can be disassembled and be cleaned, avoid sizing material that jaundice is caused to black because the residence time is too long to greatest extent, and be brought out
When will product surface lead to the problem of jaundice black.
The needle 2 is driven by straight line driving mechanism 4 (hydraulic mechanism and any equal energy of pneumatic mechanism drive) in the valve
32 slide up and down in needle passageway, and the straight line driving mechanism 4 is fixed on the flow distribution plate 1, the straight line driving mechanism 4 and institute
It states and is equipped with thermal insulation board between flow distribution plate 1.Sizing material is flowed in hot flow path 11 after passing through heat fusing with semi-fluid state, thus point
Flowing plate 1 is hotter, in order to maintain temperature of the straight line driving mechanism 4 on flow distribution plate 1 to be maintained within normal range (straight line driving mechanism
4 temperature continuously worked normally), in straight line driving mechanism 4 with being equipped with thermal insulation board, the front driving mechanism avoided between flow distribution plate 1
Temperature is excessively high, guarantees 4 the operation is stable of straight line driving mechanism.
The flow distribution plate 1 is equipped with glue-feeder 6, and the glue-feeder 6 is connected to glue-injection machine.Sizing material is infused by glue-feeder 6
Enter into hot flow path 11, the power that the pressure provided by glue-injection machine flows in hot flow path 11 as sizing material.
As shown in figure 4, the plunger 12 includes plug 121, the end face of 121 side of plug is equipped with pulled-out holes
1211, the end face of 121 other side of plug and the ontology 31 cooperate.Stop sizing material to flow to plug 121 using ontology 31, keeps away
Exempt from 2 back side of needle and deposits glue, it will be in product surface when avoiding sizing material that jaundice is caused to black because the residence time is too long, and being brought out
Jaundice is led to the problem of to black.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
