Abstract
The utility model discloses a three channels feeding die head extrusion equipment, including feeding seat, inlet pipe, connecting block and die head. The plastic melt passes through screw extruder and gets into the feeding seat, gets into a left side in, three inlet pipes on the right side through the inside trident runner plastic melt reposition of redundant personnel of feeding seat. The device can make die head both sides melt pressure balanced, can solve the high problem of film both sides shrinkage factor.
Description
Technical field
The utility model relates to a kind of triple channel feed die extrusion equipment, belongs to the field shaping technique of plastics.
Background technology
When producing plastic sheeting, first through plastic extruder, plastic pellet is melt into plastic melt, in a special film tool, forms melt extrusion film forming, then through embossing cooling, finally by rolling-up mechanism, the film take-up of curing molding is packed.But melt is in die head extrusion, because melt enters in the middle of die head, then to both sides diffluence, make melt intermediate pressure high, pressure at two ends is low, and cause melt pressure to distribute uneven, the film both sides shrinkage factor extruded is high, this contraction problem can cause the dissatisfied, anxious to be resolved of user's use procedure.
Summary of the invention
For overcoming above-mentioned technical problem, the utility model proposes and a kind of die head both sides melt pressure is evenly distributed, solve the high triple channel feed die extrusion equipment of plastic sheeting both sides shrinkage factor.
Technical solution of the present utility model is achieved in that a kind of triple channel feed die extrusion equipment, and comprise feed arrangement and die head, described feed arrangement comprises charging seat, and three feed pipes be connected with charging seat; Centre and the both sides of described die head are provided with contiguous block, and contiguous block inside is provided with and turns to passage, and one end of passage communicates with feed pipe, and the other end communicates with the runner of die head.
Further, described die head comprises the end cap at mould and sealed mold two ends, has right-angle steering passage in described end cap, and the right-angle steering passage end in end cap communicates with the passage that turns in contiguous block, and the other end communicates with the runner in mould.
Further, heating rod is inserted with in described end cap.
Further, described equipment also comprises two and turns to contiguous block, turns to contiguous block inside to have and turns to passage, and the passage that turns to being positioned at the contiguous block of both sides passes through to turn to the passage that turns to of contiguous block inside to communicate with feed pipe.
Further, turn to described on contiguous block and be provided with valve.
Further, turn in contiguous block described in and be inserted with heating rod.
The beneficial effect of the utility model employing technique scheme is: plastic melt enters charging seat by screw extrusion apparatus, then guided by the trident runner in charging seat, plastic melt flows into three feed pipes respectively, then centre and the both sides of die head are flowed to respectively, achieve the mode of both sides and middle charging simultaneously, die head both sides melt pressure is balanced, solves the problem that product both sides shrinkage factor is high, save raw material, reduce cost.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, a kind of triple channel feed die extrusion equipment, comprise feed arrangement and die head, described feed arrangement comprises charging seat 1, and three feed pipes 3 to be connected with charging seat 1 (charging seat 1 inside is provided with plastic melt runner, and in Trident Type); The centre of described die head and both sides are provided with contiguous block 4, and contiguous block 4 inside is provided with and turns to passage, and one end of passage communicates with feed pipe 3, and the other end communicates with the runner of die head.Plastic melt enters charging seat 1 by screw extrusion apparatus, then guided by the trident runner in charging seat 1, plastic melt flows into three feed pipes 3 respectively, then centre and the both sides of die head are flowed to respectively, achieve the mode of both sides and middle charging simultaneously, die head both sides melt pressure is balanced, solves the problem that product both sides shrinkage factor is high.
As shown in Figure 2, described die head comprises the end cap 5 at mould 6 and sealed mold 6 two ends, and have right-angle steering passage in described end cap 5, passage end communicates with contiguous block 4, and the other end communicates with the runner in mould 6.Plastic melt enters charging seat 1 by screw extrusion apparatus, then guided by the trident runner in charging seat 1, plastic melt flows into three feed pipes 3 respectively, fluid in the feed pipe 3 of dual-side is successively by the right-angle steering passage turned in passage, end cap 5 of contiguous block 4 inside, and level flows into the runner in mould 6.
In Fig. 2, equipment also comprises two and turns to contiguous block 7, turn to contiguous block 7 inside to have and turn to passage, the passage that turns to being positioned at the contiguous block 4 of both sides passes through to turn to the passage that turns to of contiguous block 7 inside to communicate with feed pipe 3, material flow through feed pipe 3 ?turn to contiguous block 7 ?contiguous block 4, finally enter the runner in mould 6.Turn on contiguous block 7 and can be provided with valve 8, as shown in Figure 3.Regulated uninterrupted and the switch of plastic melt by valve 8, subsequently melt enters die head from both sides and centre respectively by the contiguous block 4 on die head and crosses, and finally extrudes from die orifice.
Described end cap 5 and/or turn in contiguous block 7 and can be inserted with heating rod, for melt heating.
Content described in this description embodiment is only exemplifying the way of realization that utility model is conceived; protection domain of the present utility model should not be only limitted to the concrete form that embodiment is stated, protection domain of the present utility model is also and in those skilled in the art according to the thinkable equivalent technologies means of the utility model design.
