Description
Technical field
The present invention relates to plastics machinery of a kind of interior heating and preparation method thereof, the plastics machinery technical field of heating in belonging to.
Background technology
In the prior art, plastic granulator, plastic regenerator, injection machine, blow moulding machine, extruding machine and plastic mixer generally adopt the design that the heating of electric furnace heating wire heating collar is installed on the machine pipe of screw rod.In use there are some problems in this design: the one, and waste of energy distributes partial heat energy to be wasted in the space because the cylindrical of the electric furnace heating wire heating collar of this design and part machine pipe cylindrical are exposed.The 2nd, plasticizing is slow; because this design can only be by the hole wall heating plasticizing plastics of machine pipe; the plastics plasticizing of pressing close to hole wall in the machine pipe comparatively fast and more abundant; then plastify slow and abundant inadequately from hole wall plastics far away; for solving this technical problem, produce plastic granulator and adopt two plastic granulators to be connected with extruding machine is normal, the ripe plastics after the plasticizing are carried out a homogenizing plasticizing again; this connection type is called mother and sons' type, just will make an estrade machine more.The 3rd, the plastics flow velocity is slow and production efficiency is low, because this design only relies on machine pipe orifice wall heating plasticizing, the pore wall plastics plasticizing a little further of disembarking is abundant inadequately.For addressing this problem, except that employing mothers and sons machine plastifies in succession repeatedly, also taked the core diameter of thread to be divided into 2 to 3 sections from depth to shallow designs of asymptotic expression gradually, forced plastics in the screw slot in the machine pipe to press close to the machine inside pipe wall repeatedly and flow several times, made it fully plastify ripe material.So, the core diameter of thread is shallow, and the space and the capacity of pitch have also just diminished, and have also limited the flow of plastics.If improve the flow velocity and the production efficiency of plasticizing plastics, and be subjected to the restriction of machine pipe orifice wall plasticizing rate and ability with the rotating speed that improves screw rod.Therefore; most enterprises of the plastics machinery of China's production at present only produce and produce 10 tons daily with interior middle-size and small-size plastic granulator, extruding machine and injection machine; be controlled in a few countries hands such as the U.S., Germany, Japan and produce the key technology medium-sized, large-scale plastic granulator that reaches 200 tons, 500 tons, 800 tons every day, the large-scale plastic granulator that China needs relies on import for a long time always.The design that the plastic granulator of daily output more than 100 tons adopts deep fat to heat more; the plastic granulator that this deep fat is heated is at the machine pipe cylindrical of the screw rod sleeve pipe of burn-oning the machine pipe to be wrapped; there is individual interlayer the centre; deep fat circulates in the interlayer the inside; oily temperature is passed to the machine pipe, and the machine pipe passes to plastics to be plastified in the machine pipe to temperature again.The plastic granulator of this hot oil type is made more complicated; for segmentation control temperature; its machine pipe needs to couple together after the segmentation manufacturing again; its Circulation and Hot Oil Spray need be made many parts such as fuel tank, high temperature oil pump and hot oil pipeline; its cost height; price is also high, and the price of producing 300000 ton large-scale plastic granulators as a cover per year needs 8,000,000---and 1,000 ten thousand dollars.And a made in China cover is produced just 100,000 to 300,000 yuans of the prices of the plastic granulator that the electric furnace heating wire heating collar is installed on 3600 tons of machine pipes per year.For solving the situation of long-term dependence on import, in national development plan has just been listed the large-scale plastic granulator of development in the enforcement period of the seventh five-year plan by China.But to this year, only there is a tame enterprise in the whole nation at the large-scale plastic granulator of developing 200,000 tons of annual outputs.
For overcoming plastics machinery waste electric energy, plastifying problems such as slow, that production efficiency is not high, my development and design the heating spiral rod of processing plastic machine, and submit application for a patent for invention to China Intellectual Property Office on January 14th, 2007, the number of applying for a patent is: 2007102025287.Also submit simultaneously utility application to, granted patent number is: ZL200720201359.0.Problems such as the technology of 2007102025287 and the ZL200720201359.0 that authorized of aforementioned application has overcome original plastics machine waste electric energy effectively, plasticizing is slow, production efficiency is high inadequately.But, I find that in the trial-manufacturing process of reality application for a patent for invention numbers 2007102025287 and utility model patent grant number ZL200720201359.0 also come with some shortcomings, mainly show: electric furnace heating wire, porous refractory brick and a fixed axis that is arranged in the screw rod is threaded synchronous rotation, vibrations that produce in rotation and centrifugal force constantly rub electric furnace heating wire and porous refractory brick, thereby damage the service life of electric furnace heating wire and shortening electric furnace heating wire; The 2nd, vibrations that produce in rotation and centrifugal force make between the joint and joint of electric furnace heating wire easily, it is loosening to produce between plug and the socket, thereby cause fault easily.
Exist not enough at application for a patent for invention numbers 2007102025287 and utility model patent grant number ZL200720201359.0; further designed the plastics machinery of interior heating in person in conjunction with the reality of dissimilar plastics machineries, the plastic granulator of heating, the plastic regenerator of interior heating, the injection machine of interior heating, the extruding machine of interior heating, the blow moulding machine of interior heating, the plastic mixer of interior heating in it comprises.The plastics machinery of heating has seven new technical features in of the present invention: the one, and the interior heating pole (6) of interior heating spiral rod (5) endoporus (6.16) lining is static, interior heating pole (6) is not in company with interior heating spiral rod (5) rotation synchronously and do not produce centrifugal force, vibrations and fretting wear, so both the raising of several times the service life of interior heating spiral rod (5), also reduced fault rate to greatest extent.The 2nd, interior heating pole (6) is gone up segmentation and is provided with interior thermocouple temperature measurement head (20), can directly control the temperature of interior heating spiral rod (5) and plasticizing accurately, thereby improves plasticizing quality.The 3rd, the screw thread on the interior heating spiral rod (5) can segmentation be processed into one start screw section (5.2) and multiple thread section (5.1) respectively, and multiple thread can make the plasticizing plastics faster and better.The 4th, be provided with stirrer gear (5.5) on the interior heating spiral rod (5), stirrer gear (5.5) can stir plastics and plastify more fully.The 5th, increased the function that stirs mixing plastics; original plastic granulator and plastic mixer are different types of plastics machineries; all separate when manufacturing and use; because the present invention has set up stirrer gear and agitating function on screw rod, can carry out mixing granulator to different plastics and carry out modifying plastics processing.The 6th, be provided with the compressed air cooling system in interior heating spiral rod (5) endoporus (6.16) lining, can be interior heating spiral rod (5) fast cooling when needing.The 7th, of the present invention in the plastics machinery of heating have the faster and plasticizing characteristics such as more abundant of plasticizing, do not need to be provided with handset when manufacturing and designing, so both saved the steel of an estrade machine, also saved manufacturing cost.
