Description
Technical field
The utility model relates to the tubing production technical field, is specifically related to the small-bore single-wall corrugated pipe extrusion device of a kind of U-PVC.
Background technology
The production of producing at present the U-PVC single-wall corrugated pipe mainly contains single screw rod and extrudes with twin-screw and extrude dual mode.It is that mode through adopting single screw rod to extrude again after the granulation is produced that single screw rod is extruded.But single screw extrusion machine is sheared inadequately because plasticizing effect is relatively poor, can only lean on the ambient temperature of fuselage to satisfy the plasticizing requirement of material, so there is the uneven problem of plasticizing.The pipe workpiece quality that this kind mode is produced is very unstable, and is bad during fashion.If select for use the U-PVC twin-screw to extrude production, the screw rod of extruder and the cooperation of barrel are had relatively high expectations.It is as shown in Figure 1 that the U-PVC twin-screw of prior art is extruded production equipment, and the major part of mouth mould 3 and core 5 will stretch in the make-up machine during owing to production, can't heat it.The design of cross section and die holder 1 of adding whole device is unsuitable excessive and oversize, so the heating collar power at die holder 1 place is limited, materials flow speed is certain.A is blown into compressed air channel 7 from Fig. 1 compressed air and shaping mould rotate and will take away great amount of heat from mouth mould 3 and core 5, so the heat disequilibrium of mould, cause the temperature of mouth mould 3 and core 5 of equipment in the production process lower.Because the flat segments of mouthful mould 3 and core 5 is longer, the cross section of runner is narrower, and therefore material flow velocity herein obviously slows down, and shearing force strengthens, and it is very serious to make that material refluxes in barrel.So just can only solve the problem that flow velocity slows down through in prescription, increasing lubrication prescription.But product then is difficult to moulding behind the consumption of increasing lubrication prescription, and the wall thickness of product can not get effective control after the moulding, and lubrication prescription is prone to outer analysing, and end properties is very poor.
Because many deficiencies that above-mentioned production equipment exists; Make the single-wall corrugated pipe of present domestic U-PVC DN16～DN63 produce that ubiquity actual production efficient is lower, production process is very unstable; Also have material prescription is required harshness; Problems such as manufacturing cost is higher, and can't guarantee the quality of finished product tubing.The main bottleneck of prior art is that the temperature of extrusion die mouth mould and core is not controlled effectively; The compressed air that is blown in the bellows through compressed air channel is the main cause that causes mould core and runner cooling, and this point is often ignored by we engineers and technicians.
Summary of the invention
The technical problem that the utility model solves is the deficiency that overcomes prior art, provides a kind of and enhance productivity, simplify production technology and improve the single-wall corrugated pipe extrusion device of finished product pipe performance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is following:
A kind of single-wall corrugated pipe extrusion device comprises shell, is located at core in the shell and the runner that is formed by the space between said shell and the core; Said shell comprises die holder and the mouth mould that is connected with die holder, and said core comprises to be located at mouthful core at mould place and to be located at the branch flow cone that the die holder place is connected with core; Place, the axle center of said core is provided with the voltage supply compressed air channel that air imports that contracts, and said compressed air channel is connected with the gas-tpe fitting that is arranged on die holder one side at minute flow cone place; The said gas-tpe fitting other end is communicated with the compressed air temperature adjusting device, and said compressed air temperature adjusting device comprises the gas piping that heating arrangements, thermoregulation mechanism and voltage supply stream of compressed air are logical.The single-wall corrugated pipe extrusion device of the utility model is through being provided with the compressed air temperature adjusting device; Can carry out heat treated in advance to the compressed air of the compressed air channel that is blown into core; Thereby after the compressed air after the heating feeds; Can improve the temperature of extruding branch flow cone and core, satisfy the requirement of production technology, prevent to expect that Yin Wendu crosses low hold-up in runner and occur to reflux and the high shear phenomenon.So just can look like in the prior art to strengthen the addition of lubrication prescription, simplify production technology, improve the quality of tubing simultaneously for anti-backflow.Simultaneously, because improved the flowing velocity of material in runner, the materials temperature guarantees the stable of mouthful mould, also improves its production efficiency.
Further, the gas piping of said compressed air temperature adjusting device is repeatedly the serpentine configuration of bending.Through prolong the path that compressed air is walked in the compressed air temperature adjusting device, prolong heat time heating time like this, improve the efficiency of heating surface.
Further, said compressed air temperature adjusting device also comprises temperature sensor, and said temperature sensor is electrically connected with thermoregulation mechanism.Can control heated compressed-air actuated temperature comparatively accurately like this, adjust the operating power of heating arrangements as required.
Compared with prior art; The beneficial effect of the utility model technical scheme is: the utility model is regulated compressed-air actuated temperature through the compressed air temperature adjusting device is set; Can carry out heat treated in advance to the compressed air of the compressed air channel that is blown into core; Thereby improve the temperature extrude branch flow cone and core, satisfy the requirement of production technology, prevent to expect that Yin Wendu crosses low hold-up in runner and backflow and high shear phenomenon occur.So just can look like in the prior art to strengthen the addition of lubrication prescription, simplify production technology, improve the quality of tubing simultaneously for anti-backflow.Simultaneously, because improved the flowing velocity of material in runner, the materials temperature guarantees the stable of mouthful mould, also improves its production efficiency.
