Abstract

The utility model relates to an improved extruder, comprising a screw rod arranged in a cylinder body, a plurality of external heating rings uniformly distributed on the outer periphery of the cylinder body and a motor driving the screw to extrude, propel and plasticate plastic coming from a hopper. The utility model is characterized in that a preplasticizing chamber provided with a plurality of splitter boxes is also connected to one side of the cylinder body; a heating plate is arranged on the preplasticizing chamber. The plastic is extruded, propelled and plasticated by a plurality of the splitter boxes to achieve the purpose of full plastication; the utility model has the advantages of high product quality and high productive efficiency.

Description

Follow-on extruder

The utility model relates to screw extruder, refers to a kind of follow-on extruder especially.

Be the protection environment, solve white pollution, waste or used plastics be processed into the problem that people extremely pay close attention to, the regeneration of plastics is paid attention to by increasing people, the general screw extruder that adopts pushes propellings, heating, melts plastics in the prior art.Referring to screw extruder shown in Figure 6, screw rod places in the cylindrical shell, and the periphery circle of cylindrical shell is evenly equipped with outer heating collar, and the microscler screw rod of a driven by motor advances, pushes, carries out simultaneously melt processed to the plastics that enter from feed hopper.Find in the practice: in plasticizing process, be difficult for temperature control, plasticizing capacity is poor, long because of screw rod again, torsion is big, and it is big that consumption drives power, and screw rod is easy to wearing and tearing, plastics of its incompatible different molten index and can not produce cold plastics, matter is measuredly extruded, plasticizing effect so be difficult to reach.

The purpose of this utility model is: at the problems referred to above, on the basis of existing screw extruder, develop a kind of existing screw rod and extrude progradation, a kind of follow-on extruder of multi-stage diffluence groove effect is arranged again.

The purpose of this utility model also is: a kind of plasticizing effect, saving driving power of improving is provided, reduces cost, with a kind of follow-on extruder that improves the quality of products.

The purpose of this utility model is achieved in that a kind of follow-on extruder, it comprises: a screw rod places in the cylindrical shell, the periphery circle of cylindrical shell is evenly equipped with a plurality of outer heating collars, one driven by motor screw rod pushes, advances, plastifies the plastics that enter from feed hopper, it is characterized in that: also be connected with a plasticizing chamber with a plurality of splitter boxs in a side of cylindrical shell, this plasticizing chamber is provided with heating plate.

The purpose of this utility model also can be achieved through the following technical solutions: a plurality of splitter boxs divide three grades at least, the splitter box of each grade increases progressively by Geometric Sequence, as being provided with in the first order to divide in three splitter boxs, the second level to have to divide in six splitter boxs, the third level 12 splitter boxs is arranged.

Above-mentioned plasticizing chamber is rectangle, and its top and bottom are provided with can be by the heating plate of temperature controller adjusting.Plastics through shunting, heating, the fusing of a plurality of splitter boxs, reach the purpose of fusing fully under the promotion of screw rod.

1., under the shunting action of a plurality of splitter boxs the utility model has the advantages that:, plasticizing effect, percent defective reduction have been improved, 2., owing to adopted short screw as propeller, so reduced torsion, save driving power, reduced cost, 3., temperature control (be plastics under the shunting action of a plurality of splitter boxs, be difficult for self and produce the intensification phenomenon) easily in the production process, 4., speed is fast in process of production, output is high, service life of equipment is long.

This practicality newly further specifies by the following drawings and embodiment:

Fig. 1, be the total schematic diagram of structure of the present utility model.

Fig. 2, for the plasticizing chamber structural representation.

Fig. 3, be the A-A cutaway view among Fig. 2.

Fig. 4, be the B-B cutaway view among Fig. 2.

Fig. 5, be the C-C cutaway view among Fig. 2.

Fig. 6, be the prior art constructions schematic diagram.

Referring to Fig. 1-5, a kind of follow-on extruder, it comprises: a screw rod 3 places in the cylindrical shell 4, and the periphery circle of cylindrical shell 4 is evenly equipped with 3 pairs of plastics that enter from feed hopper 2 of a plurality of outer heating collar 5, one motors, 1 drive screw rods and pushes, advances, plastifies; Also be connected with a plasticizing chamber 7 with a plurality of splitter boxs in a side of cylindrical shell 4, this plasticizing chamber 7 is provided with heating plate 8.

Above-mentioned a plurality of splitter box divides three grades at least, and the splitter box number in each grade increases progressively by Geometric Sequence.As being provided with in the first order to divide in three splitter boxs, the second level to have to divide in six splitter boxs, the third level 12 splitter boxs are arranged.Entering the interior plastics of the first order has been the moving state of semi-fluid, and propulsive force can hand on step by step, and level is mobile backward owing to continuous heating of plastic, and mobile performance is just good more, and needed motive force is just more little.

Above-mentioned plasticizing chamber 7 is rectangle, and its top and bottom are provided with can be by the heating plate 8 of temperature controller adjusting.

The utility model has increased effective contact area owing to changed the way of contact of heating plate 8 with plasticizing chamber 7, makes the plastics that enter plasticizing chamber 7 just can finish heating plasticizing with the short time under the effect of three grades of splitter boxs.

After former screw extruder transform the utility model as, leading portion still keeps screw rod as angle of rake effect, but the length of screw rod is 1/2 to 1/3 of prior art, and main heating plasticizing process is to finish by the utility model of back segment, so the shortening of spiro rod length, has improved stressed (mainly being torsion) situation of screw rod, with under the constant power, can improve revolution greatly, thereby improve the speed that plastics advance, reach the purpose that improves output.

Relative prior art, the utility model is made the net sectional area of plasticizing chamber greatlyyer, by front The plastics that the section screw rod promotes increase in the indoor unit circulation of plasticizing, and namely plasdcizing rate obtains increasing this practicality Novel effective heating surface to plastics is bigger than the simple heating surface (area) (HS of screw that adopts, so plastics are in the plasticizing chamber In reach the corresponding minimizing of time of complete heat fused, thereby illustrated that also the utility model carries than prior art High plasticizing capacity.
