Description
Technical field
The invention belongs to the rubber-moulding apparatus field, relate to a kind of Rubber Extruder head, the particularly a kind of Rubber Extruder head that can extrude different cross section rubber continuously.
Technical background
The head of Rubber Extruder is a rubber extrusion forming equipment, and raw material is extruded forward in the runner of head, and through given shape the mouth mould as gum outlet, extrusion molding.Common Rubber Extruder machine head port mould fixed in shape; CN201761052U patent document like Patent Office of the People's Republic of China's bulletin on March 16th, 2011; Name is called the Rubber Extruder head and improves structure, can only produce the rubber of constant cross-section continuously, produce the rubber of different cross section and need shut down the replacement port mould; Not only influence production efficiency, and can't produce the continuous rubber strip of different cross section.And some rubber strip or rubber tube need be suitable for specific field; Need have different cross sections in different segmentations; The location of contrast agent delivery pipe that medically uses as shown in Figure 1, need be designed to leading portion is hollow circular-tube, the stage casing is the pipe that includes the right-angled intersection rib; Back segment then need have axial slit and flow out for developer solution on the tube wall that includes the right-angled intersection rib; Section has different cross sections before, during and after the rubber tube of this structure, and need be continuously shaped, obviously adopts traditional Rubber Extruder head can't realize one-shot forming.
The CN2855707Y patent document of Patent Office of the People's Republic of China's bulletin on January 10th, 2007; But announced the Rubber Extruder head that a kind of shape of the mouth as one speaks cycle changes, this device adopts the cam of periodic motion to drive the periodically gum outlet of shield portions mouth mould of shape of the mouth as one speaks baffle plate, is periodically variable rubber strip with the production cross section; The shape of the mouth as one speaks baffle plate that this device leans out from the side; Must lean out from a side of gum outlet when blocking, relatively be applicable to blocking of side, and block the position and must comprise a part of side; Be not suitable for the production of closed rubber tubing, the change of rubber strip or rubber tube center shape is also had bigger difficulty.
Summary of the invention
It is big to the objective of the invention is to produce the rubber strip difficulty of variable cross-section continuously to present Rubber Extruder head; Especially tubulose variable cross-section rubber production can't simply adopt the simple occlusion issue of block, and a kind of Rubber Extruder head that can produce the variable cross-section rubber tube continuously is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Rubber Extruder head; Establish the body of rubber runner in comprising, a side of body is provided with glue-feeder, and the front end of body also is provided with a mouthful mould; The mouth mould is provided with gum outlet; Said gum outlet place is provided with can be along the elastic plug of plastic emitting direction, and the plug bore is less than the gum outlet bore, and the front end face of plug offers the spew groove that connects the plug two sides; The plug of spew groove rear end has one section solid light rod body, and gum outlet constitutes the shape of the mouth as one speaks that rubber is extruded jointly with plug that can be elastic.When plug stretched out, solid light rod body alignd with gum outlet, formed the shape of the mouth as one speaks of ring-type, and the rubber strip that extrude this moment is the round rubber pipe; When plug is withdrawn, the side of spew groove alignment gum outlet, and bottom land is positioned at the inboard of gum outlet, rubber flows in the spew groove from the bottom land of spew groove, and together extrudes with the ring-type shape of the mouth as one speaks from notch, forms the rubber tube of inner band rib.Two kinds of shape of the mouth as one speaks can be switched with plug is flexible in real time, need not to shut down the replacement port mould, can produce the rubber tube of variable cross-section continuously.
As preferably, when said plug protracted, solid section of plug alignd with gum outlet, and when contracting behind the said plug, the spew groove section of plug is alignd with gum outlet.Two stations can switch in real time.
As preferably, said gum outlet is a round mouth, and the plug front end is the polished rod cylindricality, and said spew groove comprises two of right-angled intersection, and two spew grooves connect the plug side respectively.Gum outlet can form the shape of the mouth as one speaks of band cross rib in the pipe shape of the mouth as one speaks and the pipe.
As preferably, the drops of the bottom land cross section of said spew groove for heaving to both sides.Increase ensures that from the bore of runner entering spew groove the rubber that gets into spew groove is sufficient, improves yield rate.
As preferably, be provided with the cutting knife of some expandables outside the said gum outlet, the end edge of a knife was resisted against the plug side when cutting knife stretched out, the edge of a knife and spew groove mutual dislocation.When the edge of a knife was resisted against mandrel surface, rubber tube was extruded behind the gum outlet directly by edge of a knife cutting, forms axial slit, can form side band radial gap, in establish the rubber pipeline section of rib.
As preferably, said cutting knife is four, evenly is provided with at circumferencial direction.Corresponding with the cross rib, be opened in the slit of staggering in the rib position at the sidewall of rubber tube.
As preferably, the rear end of said plug be connected with can be elastic push rod, the push rod side is provided with axial gathering sill; Said putting back-end is provided with external screw thread; Putting back-end peripheral hardware pivoted housing, pivoted housing is provided with the internal thread that cooperates with putting back-end, and pivoted housing and push rod form the screw mandrel transmission.It is elastic to adopt the structure of screw mandrel to drive plug, and pivoted housing can adopt motor-driven, and it is flexible also can to adopt mode such as hydraulic push rod to drive plug.Plug and push rod help changing and reconfiguring for dividing body structure, and as other scheme, plug also can be structure as a whole with push rod.
As preferably, the rear outside of plug is provided with the sheath that links to each other with body, and the lateral surface of sheath front end and plug closely cooperates, the inner cavity that reduces the flexible resistance of plug that forms of sheath.When plug was elastic, if be in the rubber runner, resistance was bigger, therefore the plug rear end was arranged in the cavity resistance when the reduction plug is flexible.
As preferably, said body comprises the runner body at body fuselage and center, establishes conical cavity in the body fuselage, and the runner body has conical outer surface, and body fuselage and runner body constitute the tapered annular runner around the tapered runner body cone.The back-end sealing of sheath is fixed on the front end of runner body, the pyramidal structure of sheath Front-end Design for matching with runner, and push rod passes the axial line setting of runner body, and in the cooperation place of runner body and push rod axial guide frame is set.
But the present invention adopts telescopic plug to cooperate the different plastic emitting shape of the mouth as one speaks that forms real-time regulated with gum outlet, can not shut down the rubber tube of continuous production variable cross-section; At gum outlet arranged outside cutting knife, can cooperate plug flexible, the rubber tube tube wall is carried out axial cutting, form axial slits, the plug rear end is provided with sheath, has reduced the resistance when plug is flexible.
