Abstract
A pipe machine nose with a choke device comprises a compression plate, a nozzle mould, a nose body, a distributing bush, a distributor support, a distributor and an inner connector and is characterized in that the compression plate and the inner connector are connected to two ends of the nose body, a filter mesh plate is disposed at one end of the inner connector, a buffer mandrel is disposed at a center axis of the nose body. A choke mandrel is disposed at one end of the buffer mandrel, and the outer wall of the buffer mandrel, close to the end of the choke mandrel is provided with at least one circular groove. The outer wall of the choke mandrel is provided with at least one circular projection, and the other end of the chock mandrel is connected with the distributor. A cavity is formed between the nose body and the buffer mandrel, choke mandrel and distributor. The nozzle mould, the distributing bush and the distributor support are sequentially connected and are located in the cavity. Compared with the prior art, the pipe machine nose is provide with the buffer mandrel having the circular grooves, so that performance of plasticizing materials is improved and welding marks generated on the distributor support are eliminated.
Description
Technical field
The utility model relates to a kind of head of plastic pipe molding processing, especially relates to a kind of tubing head with choke apparatus.
Background technology
The common pipe extruder head mould of current production mainly contains two kinds of forms.A kind of is the through type extruder head, its head simple in structure, easy to manufacture, cost is low, and it is consistent with the extruder screw axis that direction is extruded in logistics, material is little in the mobile power-assisted of head, tubing and head, machine barrel three are coaxial, the easy extrusion molding of tubing, but the material compacting degree is relatively poor, rough surface and glossiness are bad, are prone to the sharkskin phenomenon; And the joint line that produces of the shunting muscle on the current divider support, make the strength decreased of tubing.Another kind is the right-angle type extruder head, although effect is much better, complex structure is made difficulty, and cost is high.Even adopt improved through type extruder head, its effect is also not obvious, for example CN 201889896U discloses a kind of mixing-type plastic pipe extrusion machine head, mainly comprise handpiece body, current divider, core, mouthful mould, air intake lever, the outside of described handpiece body, handpiece body is provided with heating collar, and described handpiece body has adjustment screw to be connected with a mouthful mould; Described handpiece body is provided with pressure ring with the outside of mouthful mould, described pressure ring is connected by hold-down screw with handpiece body, it is characterized in that: be provided with blender between described handpiece body and the current divider, described blender is the cylinder of some through holes, and described through hole correspondence is arranged in the channel.Its weak point is, when material is extruded material press and flow velocity shakiness, plasticizing capacity poor, and current divider easily produces weld mark, product surface is coarse.
Summary of the invention
Material was pressed and the flow velocity shakiness when the purpose of this utility model was to solve common plastics cross-head extruding pipe material, surface gloss is poor, and easily produce the problem of weld mark, and then can voltage stabilization and current stabilization when providing a kind of material to extrude, its product surface glossiness is good and be difficult for producing the tubing head with choke apparatus of weld mark.
The utility model comprises pressure strip, the mouth mould, handpiece body, diversion sleeve, the choked flow plug, the current divider support, current divider and internal layer connector, the two ends that it is characterized in that handpiece body are connected with pressure strip and internal layer connector, internal layer connector one end all is provided with screen pack, the handpiece body central axis is provided with the buffering plug, the buffering plug is provided with interior hexagonal hole near that end of mouthful mould, the other end of buffering plug is provided with the choked flow plug, and the buffering plug is provided with annular groove near the outer wall of this end of choked flow plug, annular groove is at least twice, and the annular groove on the buffering plug is connected smoothed curve to connect with straight portion, choked flow plug outer wall is provided with and is at least annular boss together, its choked flow plug one end links to each other with the buffering plug, the other end links to each other with current divider, the buffering plug, form a cavity, its mouthful mould between choked flow plug and current divider and the handpiece body, diversion sleeve and current divider support connect successively and are positioned in the above-mentioned cavity.
The utility model adopts the buffering plug be provided with annular groove, improve the plasticizing capacity of material and eliminate the weld mark that produces in the current divider support, and material when extruding material press and flow speed stability.
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, 1 is pressure strip, and 2 is interior hexagonal hole, and 3 is a mouthful mould, and 4 is handpiece body, and 5 is diversion sleeve, and 6 are the buffering plug, and 7 are the choked flow plug, and 8 is the current divider support, and 9 is current divider, and 10 is the internal layer connector, and 11 is screen pack.
Figure has shown the structural representation of the tubing head of the utility model band choke apparatus.Wherein 4 is handpiece body, the two ends of handpiece body are connected with pressure strip 1 and internal layer connector 10, internal layer connector one end all is provided with screen pack 11, the handpiece body central axis is provided with buffering plug 6, the buffering plug is provided with interior hexagonal hole 2 near that end of mouthful mould, the other end of buffering plug is provided with choked flow plug 7, and the buffering plug is provided with annular groove near the outer wall of this end of choked flow plug, annular groove is at least twice, and the annular groove on the buffering plug is connected smoothed curve to connect with straight portion, choked flow plug outer wall is provided with and is at least annular boss together, its choked flow plug one end links to each other with the buffering plug, the other end links to each other with current divider 9, the buffering plug, form a cavity, its mouthful mould 3 between choked flow plug and current divider and the handpiece body, diversion sleeve 5 and current divider support 8 connect successively and are positioned in the above-mentioned cavity.
[0009] operation principle: material enters head by Screw Extrusion, advanced current divider and current divider support, so that material attenuation, stir, be convenient to homogeneous heating, and then enter gap between choked flow plug and the diversion sleeve, annular boss on the choked flow plug outer wall compresses material, improved plasticizing capacity, increase the packing of product, and eliminated the joint line that the current divider support produces, material continues to be extruded forward the gap that enters between buffering plug and the diversion sleeve, and the buffering plug is provided with annular groove, but material obtains the state of more preferably voltage stabilizing and current stabilization, and further improve the plasticizing capacity of material and eliminate the weld mark that the current divider support produces, material is finally by crossing the gap extrusion molding that cushions between plug and mouthful mould.
