Field technology personnel it is recognised that the first cylinder 431 and the second cylinder 432 can also be fixed in the other positions of pouring head,
Such as on the fixation disk 41 of mixing chamber 4.
432 structure having the same of first cylinder 431 and the second cylinder, by taking the first cylinder 431 as an example, with reference to Fig. 5, first
Cylinder 431 includes cylinder body 4311, piston rod 4312, left connecting rod 4313, right connecting rod 4314, left rotary shaft 4315,4316 and of right spindle
Fixed part, wherein fixed part include locating slot and mounting hole.Piston rod 4312, left rotary shaft 4315 and right spindle 4316 are arranged in cylinder
4311 downside of body, left rotary shaft 4315, right spindle 4316 are located at the both sides of piston rod 4312.The middle part of piston rod 4312 has
Connecting rod coupling part, connecting rod coupling part are groove 43121 or through-hole.Left connecting rod 4313, right connecting rod 4314 are preferably in inverted butterfly
Butterfly-type, is provided with shaft hole therebetween respectively on position, left connecting rod 4313, right connecting rod 4314 are fixed by respective shaft hole
Onto left rotary shaft 4315, right spindle 4316.Left connecting rod 4313, right connecting rod 4314 one end mobilizable be inserted into piston rod 4312
Connecting rod coupling part, the other end of left connecting rod 4313 is inserted into the open/close through hole 42142 of the first valve rod of needle valve 4214, right connecting rod
4314 other end is staggeredly inserted into the open/close through hole of the second valve rod of needle valve.
As a result, when cylinder 431 drives piston rod 4312 to move down, piston rod 4312 drives downwards its middle part coupling recessed
An end motion of the left connecting rod 4313, right connecting rod 4314 of activity setting in slot so that left connecting rod 4313, right connecting rod 4314 are around each
The axis of rotation 4315,4316 rotates, and left connecting rod 4313 is inserted into the other end in the open/close through hole 42142 of the first valve rod of needle valve 4214
The other end being inserted into right connecting rod 4314 in the open/close through hole of second valve rod of needle valve moves upwards respectively, lifts first, second
Valve rod of needle valve opens the first, second needle-valve, injects raw material into the accommodation space of mixing chamber.Same principle, the second cylinder can be with
It is synchronous to open second, third needle-valve, corresponding raw material is injected into the accommodation space of mixing chamber.
In the present invention, the situation certain in the cylinder piston throw of lever, can be by adjusting adjusting bolt in open/close through hole
Screw-in length in space controls the aperture of corresponding needle-valve.
It should be noted that in the present invention, the needle-valve that can be controlled by two cylinders, such as the second needle-valve, in the same time
It is controlled by one of cylinder, another cylinder does not work.As shown in Figure 3,4, due to the one of the right connecting rod of the first cylinder 431
One end of the left connecting rod of end and the second cylinder is inserted into the open/close through hole of the second needle-valve 422 simultaneously, is opened in the first cylinder 431
While second needle-valve, the open/close through hole lower edge of the second needle-valve 422 undesirable can touch the left connecting rod of the second cylinder 432, and
The left connecting rod of the second cylinder 432 may be driven to move upwards, and lead to the movement of the second cylinder 432, third needle-valve 423, in order to
Avoid such case, those skilled in the art that the length of the open/close through hole of the second needle-valve 422 according to actual conditions, can be appropriately arranged with
Spend size.
Preferably, the present invention needle-valve in, by three-port structure carry out raw material supply, needle-valve of the invention have into
Material mouth, feedback outlet and valve opening, raw material are pumped into from feed inlet in needle-valve, and when needle-valve is closed, raw material is returned from feedback outlet, to
Feed liquid circulation is carried out in circulation line；When needle-valve is opened, part material is injected into the accommodation space of mixing chamber from valve opening
In, remaining raw material is returned from feedback outlet.
Purge valve 44 is installed, cleaning solution can be controlled by purge valve 44 to be injected by cleaning solution on cleaning solution inlet 413
Mouth 413 is injected into the accommodation space of mixing chamber, and then can be cleaned to the batch mixing space of pouring head.
In preferred embodiment above, the structure (three are coupled structure) of two cylinders, this field skill are equipped with using three needle-valves
Art personnel are it is recognised that individually can also use a cylinder to control two needle-valves, as shown in Figure 7.
When according to technique needs, there is the AB material for needing to inject multigroup component intersection, can be used more than three multi-joint
Structure, but adjacent cylinder will not work at the same time, as shown in Figure 8.In fig. 8, including two are injected the needle-valve of A1 material, an injection
The needle-valve of needle-valve and an injection B2 material that the needle-valve of A2 material, an injection B1 expect.Cylinder B1-A1 be used for and meanwhile control its two
The unlatching of side needle-valve, to inject raw material A 1, B1 simultaneously；Cylinder B1-A2 is used for while controlling the unlatching of its both sides needle-valve, with simultaneously
Inject raw material B1, A2；Cylinder B2-A2 is used for while controlling the unlatching of its both sides needle-valve, to inject raw material B2, A2 simultaneously；Cylinder
B2-A1 is used for while controlling the unlatching of its both sides needle-valve, to inject raw material B2, A1 simultaneously.As a result, in PU material manufacture processes
In, different AB material can be squeezed into, such as open not phase simultaneously according to technological requirement by pouring head mixing chamber shown in Fig. 8
Two adjacent cylinders manufacture different PU products, and without frequent replacement, adjustment, wash feed access.
The preferred embodiment of the invention is illustrated above, but the invention be not limited to it is described
