Description
Technical Field
The utility model relates to a separator type screw rod structure suitable for plastics regeneration granulation belongs to plastics production facility field.
Background
In the prior art, a common screw is only provided with 1 main tooth or 2 threads which have the same diameter and are communicated end to end, the rotating speed block adding plasticizing effect is poor, the yield is low, and in the last 70 th century, a separation type screw has been developed in China and has the main structural characteristics of double threads, wherein the diameter of an auxiliary thread is 0.4-0.6cm smaller than that of the main tooth, and molten plastic can only reach an auxiliary screw groove through a gap, so that the molten plastic and the unmelted plastic are separated, and the melting of the plastic in the main screw groove is promoted. The former separating screw has the diameter of 45-90cm, the length-diameter ratio of 16-30 and low yield, the aimed raw materials are new materials, granules, clean impurities are few, the transition length between the starting position and the ending position of the auxiliary tooth and the main tooth is short, only one circular arc is used for transition, and the transition is not smooth.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims at providing a separator type screw rod structure suitable for plastics regeneration granulation to solve the problem that proposes in the above-mentioned background art, the utility model discloses to plastics regeneration granulation, output is big, and the quality is high, screw rod long service life, vibrate for a short time, the noise is low, does benefit to dual filtration.
In order to achieve the above purpose, the present invention is realized by the following technical solution: the utility model provides a separator type screw rod structure suitable for plastics regeneration granulation, includes the screw rod body, screw rod body annular side welded fastening has main thread and vice thread, main thread sets up with vice thread is crisscross, and vice thread is located screw rod body annular side middle part position, it has vice thread groove to process between main thread and the vice thread, interval between the vice thread shortens from the left hand right side in proper order, the width of vice thread groove length of side length in proper order from the left hand right side, the diameter of the screw rod body length of side length in proper order from the left hand right side, main thread diameter is the same with vice thread diameter.
Furthermore, the right end of the screw rod body is connected with an external screw rod in a sealing mode through a reverse tooth sealing piece.
Furthermore, the diameter of the auxiliary screw groove is larger than that of the screw rod body and smaller than that of the main screw tooth and the auxiliary screw tooth.
Further, the diameter of the screw rod body is 150-200cm, and the length-diameter ratio is 33.
The utility model has the advantages that: the utility model discloses a separator type screw rod structure suitable for plastics regeneration granulation, through the interval between main thread and the vice thread transition gradually, and the changeover portion extension, plastics compression and release are more smooth and easy, avoid making plastics backward flow and intensification because of the sudden compression of plastics produces great reaction force, avoid producing the space because of the sudden release of plastics and form the gas pocket, thereby output and plastics quality have been promoted, screw rod long service life, the vibration is little, the noise is low, do benefit to dual filtration, separation type screw rod before having solved, the diameter is little, draw ratio is little, output is low, its raw materials to be new material, the graininess, clean impurity is few, the originated and the transition length of ending department and main tooth of vice tooth is short, only a circular arc transition, the problem that the transition is not smooth and easy.
