The distributor provided by the invention is simple in structure; different proportion requirements can be met by quickly adjusting the flow speed of the materials in the cavities.

Description

A kind of distributor

Technical field

The present invention relates to sheet material extrusion device, refer to especially a kind of distributor.

Background technology

While adopting multi-layer co-extruded compound mode to produce plastic package material (as plastic sheeting, plastic sheet and plastic plate), by distributor, multilayer material is combined with each other equably, have save material, material can variation, need not poisonous adhesive, meet the advantages such as environmental requirement, and combination is good between the layers of material of plastic package material, gas barrier effect is very good.

But, in the market the distributor in this sheet production line flexibly the flow of different materials to tackle different ratio demands, thereby affect accuracy and the uniformity of articles of sheet material layers of material thickness.Meanwhile, in actual production, can not the requirement of flexible adaptation different materials to different cavity shape.

Summary of the invention

In order to address the above problem, the invention provides a kind of distributor.A kind of distributor provided by the invention, simple in structure, can quick adjustment cavity in the flow velocity of material to tackle different ratio demands.

Technical scheme of the present invention is achieved in that

A kind of distributor, comprise housing, described enclosure interior arranges stream cavity, and described stream cavity comprises a primary flow path cavity and four Zhi Liulu cavitys, described primary flow path cavity is communicated with respectively with between each stream cavity, also comprises the active plugboard that primary flow path cavity and Zhi Liulu cavity are separated.

Above-mentioned a kind of distributor, wherein, described primary flow path cavity laterally runs through enclosure interior center, the head end of described primary flow path cavity is main feeding mouth, and the end of described primary flow path cavity is discharging opening, and described main feeding mouth is arranged on the left side of housing, described discharging opening is arranged on the right side of housing, the head end of described Zhi Liulu cavity is a feeding mouth, and described feeding mouth is symmetrically distributed in the both sides, front and back of housing, and the end of described Zhi Liulu cavity is connected with primary flow path cavity.

Above-mentioned a kind of distributor, wherein, described enclosure interior arranges shunt shaft, and described shunt shaft is through primary flow path cavity and each stream cavity, described shunt shaft be provided with for be communicated with the main channel of primary flow path cavity with for being communicated with the subchannel of at least one stream cavity.

Above-mentioned a kind of distributor, wherein, described shunt shaft arranges four subchannels.

Above-mentioned a kind of distributor, wherein, also comprise control valve, described control valve is arranged on the end of each stream cavity, described control valve comprises throttle block, connecting axle, adjusting rod and fixed head, described throttle block is fixed on connecting axle, described connecting axle is arranged on enclosure interior and has one end outside housing, described adjusting rod and fixed head are arranged on hull outside, the two ends of described fixed head one side are provided with two projections, described projection arranges screw, in described screw, adjusting bolt is set, described two adjusting bolt ends are oppositely arranged, one end of described adjusting rod contacts between the end of two adjusting bolts and with the end of two adjusting bolts, the other end of described adjusting rod is connected with one end that connecting axle stretches out housing.

The invention has the beneficial effects as follows, requirement according to different materials to flow channel shape and size, by changing the active plugboard of suitable shape and size, can be quick, adjust flexibly shape and the size of intersection's runner and sprue, thereby regulate the flow of sprue, the flow of runner and both ratios, the compound region of layers of material and usage ratio are met the requirements, each layer of material tied in distributor be incorporated in extrusion die evenly, distribute fifty-fifty, thereby guarantee accuracy and the uniformity of articles of sheet material layers of material thickness, make the layering of final articles of sheet material even, downside by the material outlet at each runner is respectively provided with a control valve, can in non-stop-machine situation, independently regulate fast as required each runner to lead to the outlet size of sprue, to change the flow proportional of layers of material melt, make the compositely proportional of each layer reach requirement, avoid shutting down the loss that adjusting brings, and make more convenient to operate, shunting rod is removably installed in housing, makes the distributor can be in the situation that not changing main body flow passage structure, flexible adaptation be produced the requirement of several pieces materials of different layers.The present invention, by changing simply, fast or regulating, can be used in the production of different sheet materials, improves widely the utilization rate of equipment.
