Description
Technical field
The utility model relates to a kind of extruder head group, especially relate to a kind of can the Novel extruder head group of discharging.
Background technology
Be used in the three-layer insulated stranded winding wire on transformer or high frequency coil at present, by copper conductor, two layers polyester insulation and outer polyamide insulation composition, the copper conductor wire diameter of this kind of insulated wire is less, and individual layer single wall insulation thickness is more only the thin of 0.01 ~ 0.05mm.Traditional extruding machine head group is not provided with discharge valve, must shut down when reloading, and after cavity pressure reduces, mould unloading, then threading start, production efficiency is low.
Chinese patent CN 201936688U discloses a kind of Double-head extruder, by a single-head extruding machine, a newly-increased single-head, a set of head installing mechanism and a former head composition, described single-head extruding machine is common extruding machine, described newly-increased single-head redesigns according to need of production and is arranged on extruding machine, described single-head installing mechanism is used for specially installing newly-increased head, this utility model Double-head extruder, in actual production process, decrease the time required for product type replacing, particularly decrease the maintenance time required when a head breaks down, drastically increase operating efficiency, but increase a head newly, production cost is caused greatly to improve.
Utility model content
The purpose of this utility model be exactly provide to overcome defect that above-mentioned prior art exists a kind of structure simple, easy to use, accelerate thread-changing speed, enhance productivity can the Novel extruder head group of discharging.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of can the Novel extruder head group of discharging, comprise machine folder and head, described head is connected with extruding machine fuselage by machine folder, triple valve is provided with between described machine folder and head, the import of this triple valve is communicated with extruding machine fuselage, one of them outlet is communicated with head, and another outlet is discharge port.
Described triple valve top spool rotates to switch being communicated with of two outlets and import by 90 ° of horizontal angles.
Described triple valve is electric T-shaped valve.
Described three-way valve body inner flow passage chamber Roughness Surface on Control is at Ra=0.8 μm, in case sizing and block discharging opening in fluid stopping road.
Described three-way valve body adopts steel alloy material.
Described head group is applicable to the thin-walled extrusion molding of the plastic materials such as PVC, PET, TPE, TPEE, PTFE, PA.
Described head group is applied to cross section and is less than 3mm
2the production of electric wire or monolayer extrusion thickness be less than the production of the electric wire of 3mm.
The effect of triple valve is: when head does not temporarily need feed, opens the sizing material change flow direction that triple valve can make extruding machine fuselage extrude, directly discharges sizing material by triple valve without head.Mainly avoid some sizing materials to be in for a long time in high temperature machine barrel and to cause degraded very fast, or the problem of long-time screw dwell, use head group of the present utility model not need of short duration shutdown, can material waste be reduced.
Compared with prior art, the utility model has the following advantages and beneficial effect:
The utility model adds three-way valve device between the machine folder and head of extruding machine, rotates the changeable feed of triple valve spool and discharging; Can take apart a die when Quick Changeover and clear up, shortening conversion time; For the material easily causing thermal degradation after shutdown; adopt the utility model can realize not shutting down thread-changing; and can in advance to die cavity pressure release before thread-changing; accelerate thread-changing speed; enhance productivity; reduce the generation of degraded polypropylene, save the trouble of cleaning barrel and head, applicable three layer insulation wire extruding machine or conductor area are lower than 3mm
2fine gauge electric wire.
Accompanying drawing explanation
Fig. 1 is traditional electric wire extrusion head schematic diagram;
Fig. 2 be of the present utility model can the Novel extruder head group schematic diagram of discharging.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Comparative example
As shown in Figure 1, traditional electric wire extrusion head comprises machine folder 1 and head 2, and head 2 is connected with extruding machine fuselage 3 by machine folder 1, must shut down when reloading, and after cavity pressure reduces, mould unloading, then threading start, production efficiency is low.
Embodiment
A kind of can the Novel extruder head group of discharging, as shown in Figure 2, comprise machine folder 1 and head 2, head 2 is connected with extruding machine fuselage 3 by machine folder 1, triple valve 4 is provided with between machine folder 1 and head 2, the import of this triple valve 4 is communicated with extruding machine fuselage 3, and one of them outlet is communicated with head 2, and another outlet is discharge port.Triple valve 4 top spool rotates to switch being communicated with of two outlets and import by 90 ° of horizontal angles.Triple valve 4 is electric T-shaped valve.Triple valve 4 valve body inner flow passage chamber Roughness Surface on Control is at Ra=0.8 μm, in case sizing and block discharging opening in fluid stopping road.Triple valve 4 valve body adopts steel alloy material.
Head group is applicable to the thin-walled extrusion molding of the plastic materials such as PVC, PET, TPE, TPEE, PTFE, PA.Head group is applied to cross section and is less than 3mm
2the production of electric wire or monolayer extrusion thickness be less than the production of the electric wire of 3mm.
The effect of triple valve 4 is: when head 2 does not temporarily need feed, opens the sizing material change flow direction that triple valve 4 can make extruding machine fuselage 3 extrude, directly discharges sizing material by triple valve 4 without head 2.Mainly avoid some sizing materials to be in for a long time in high temperature machine barrel and to cause degraded very fast, or the problem of long-time screw dwell, use the machine head group not need of short duration shutdown, can material waste be reduced.When draw drum remaining line body and being less than 2 minutes cabling time, screw speed can be reduced, open triple valve in advance, because there is no the pressure of feed, pressure while cabling in die cavity reduces gradually, treats that cabling is complete, and cavity pressure also becomes very little, be conducive to next threading, thus reach the object improving production capacity.
Above-mentioned is can understand for ease of those skilled in the art and use utility model to the description of embodiment.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the utility model is not limited to above-described embodiment, and those skilled in the art, according to announcement of the present utility model, do not depart from improvement that the utility model category makes and amendment all should within protection domain of the present utility model.
