The invention relates to a die head device for producing a PVC sandwich layer foam board. The die head device comprises a die head body, wherein a hollow die cavity is arranged at the central axis of the die head body; the two ends of the die cavity are respectively a feed end and a discharge end of the die head body; the feed end of the die head body is provided with a multi-layer distributor; the discharge end of the die head body is provided with a die lip; two or more distribution blocks are arranged in the multi-layer distributor; each distribution block is provided with a water drop-shaped runner; and the water drop-shaped runner is connected with the die cavity. Through the invention, the produced foam board has high hardness, good impact resistance, good glossiness and excellent surface printing performance.
Description
Technical field
The present invention relates to a kind of die head device that is used to produce PVC core layer foaming plate.
Background technology
PVC foaming plate is called again avenges not plate and An Di plate, it is the new material of a kind of " to mould Dai Mu ", with polyvinyl chloride (PVC) is primary raw material, make through special foam process, have moistureproof, fire-retardant, not modification, nontoxic, attractive in appearance, advantage such as ageing resistance is strong, and fabulous corrosion resistance is arranged.
PVC core layer foaming panel forming method in the market all is by cooling off fast on individual layer foaming plate surface, thereby it is thin and without the top layer of foaming to form one deck at individual layer foaming plate plate surface.The case hardness of this class foaming plate sheet material is general, and impact strength is poor, and surface smoothness is relatively poor, and the surface printing performance is also bad.
Summary of the invention
The purpose of this invention is to provide a kind of die head device that is used to produce PVC core layer foaming plate, can effectively solve little, the problems such as impact resistance is poor, printing performance difference of individual layer foaming plate case hardness of prior art.The present invention relates to a kind of die head device that is used to produce PVC core layer foaming plate, comprise die body, the central axis of described die body is hollow mold cavity, the two ends of described mold cavity are respectively the feeding end and the discharge ends of die body, the feeding end of described die body is provided with the multilayer distributor, the discharge end of described die body is provided with die lip, be provided with two or more allocation blocks in the multilayer distributor, each allocation block is provided with a water droplet shape runner, and described water droplet shape runner is connected with mold cavity.Described die body and multilayer distributor junction are provided with the die head adpting flange.Described die lip is provided with the die lip adjusting device.The junction of described die lip and die body is provided with the throttle bar adjusting device.Described multilayer distributor is provided with adapter sleeve.Described multilayer dispenser housing place is provided with cover plate.Described cover plate is provided with two or more cover plate housing screws.Described allocation block and cover plate junction are provided with the allocation block hold-down screw.Described cover plate is provided with the allocation block top wire hole.The present invention is in physics that does not change sheet material and chemical fundamentals, hard PVC layer and hard PVC foaming layer are combined with each other uniformly, also can change the complex method of two kinds of raw materials as required arbitrarily, every layer composite thickness can be regulated separately, can can select the allocation block of different openings gap and A/F as required for use, change the composite thickness or the compound width of composite bed, even can close wherein one deck separately.The foaming plate sheet material hardness height of making, shock resistance is good, and fineness is good, the surface printing function admirable.
Description of drawings
Accompanying drawing 1 is a cross-sectional view of the present invention,
Accompanying drawing 2 is an overall structure schematic diagram of the present invention.
The present invention will be described below in conjunction with accompanying drawing.
The specific embodiment
Comprise die body 1 among the figure, the central axis of described die body is hollow mold cavity 2, the two ends of described mold cavity are respectively the feeding end 3 and the discharge ends 4 of die body, the feeding end of described die body is provided with multilayer distributor 5, the discharge end of described die body is provided with die lip 6, be provided with two or more allocation blocks 7,8 in the multilayer distributor, each allocation block is provided with a water droplet shape runner 9,10, and described water droplet shape runner is connected with mold cavity 2.Described die body and multilayer distributor junction are provided with die head adpting flange 11.Described die lip 6 is provided with die lip adjusting device 12.The junction of described die lip and die body is provided with throttle bar adjusting device 13.Described multilayer distributor is provided with adapter sleeve 14.Described multilayer dispenser housing place is provided with cover plate 15.Described cover plate is provided with two or more cover plate housing screws 16.Described allocation block and cover plate junction are provided with allocation block hold-down screw 17.Described cover plate is provided with allocation block top wire hole 18.
Adapter sleeve of the present invention directly is connected with extruder, and operating personnel can join the extruder of different size according to the output difference.The PVC raw material that extruder will contain blowing agent enters die body from feeding end, and the hard PVC of reactive blowing agent is by the compound runner in the allocation block, and promptly water droplet shape runner is containing the uniform compound one deck hard PVC layer in PVC raw material surface of blowing agent.
After multilayer raw material after compound enters die body, the water droplet shape runner of utilization lengthening drops to the laminar flow of the PVC raw material after compound minimum, owing to contain the PVC of blowing agent and the rheological behavior of hard PVC there are differences, laminar flow can occur during through common water droplet shape runner, the PVC raw material can effectively reduce laminar flow between each layer at the water droplet shape runner by this lengthening after compound.Guaranteed that each layer of multilayer PVC raw material after compound the sinuous flow phenomenon can not occur, and can be dispensed to the die head overall with uniformly.
The PVC raw material that difference in height on the allocation block that will utilize before hard PVC is compound will contain blowing agent once compresses, to reduce the cross-head pressure in extrusion.
Cover plate housing screw of the present invention is unloaded, utilize the allocation block top wire hole that allocation block and cover plate are ejected simultaneously, unload the allocation block hold-down screw, sprue 19 is installed, can be closed this layer, take off sprue 19, with the allocation block hold-down screw allocation block is fixed, can be enabled this layer.
