Installation and adjustment method of cone double barrel screw


cone double barrel screwCommonly used in extruders, so that the extruder has uniform plasticizing and mixing, high output, stable quality, wide range of adaptation, long service life,pvcDirect molding and other characteristics. Equipped with the corresponding measuring and forming die and auxiliary machines, various thermoplastic plastics, especially polyvinyl chloride powder, can be directly sent to urban management, plates, sheets, rods, films, special-shaped and other plastic products, and the modification and powder granulation process of various plastics can also be completed.

 

cone double barrel screwInstallation and adjustment method:

1After the front and rear supports are installed on the cylinder,cone double barrel screwPut the main machine frame together, do not install the large locking nut first, support the manual shaking handle before shaking to move the barrel to the direction of the distribution box to see if the barrel stop and the distribution box lip are at the same level, and preliminarily judge whether the barrel reaches the processing accuracy.

2,Remove the spline sleeve of the distribution shaft in the distribution box and measure it with a knife edge ruler.cone double barrel screwWhether the shank spline is parallel to the distribution shaft spline(Front, back, left and right). Increase or decrease the copper gasket at the front and rear supports of the barrel to adjust the spline shaft at the same horizontal position.

3,Willcone double barrel screwAfter the spline is loaded into the spline sleeve of the distribution shaft of the distribution box, manually turn the motor rotation angle and remove the spline sleeve. Repeat the above measurement steps,StraightToAny angle is in the same horizontal position(Control in the error range0.05mmWithin).

4,Willcone double barrel screwTop shaft into screw(No gasket).

5,Willcone double barrel screwAfter the spline is put into the spline sleeve of the distribution shaft of the distribution box, push the cone double barrel screw to the direction of the distribution box with the screw top plate.MoveTop dead, and then remove the screw top plate.

6,Place the dial indicator on the small end of the barrel, and put the probe head on acone double barrel screwAdjust the epitope after the head.ToBit.

7,Use a copper crowbar to hold the right screw at the bottom of the blanking opening.(Keep the screw top shaft end face and distribution shaft end face contact fit),Fixed.

8,Use a copper crowbar to push the left screw toward the machine head.untilCan move,Then read the table on the dial indicator.

9,In the same way will becone double barrel screwPushToAt the top of the distribution shaft of the distribution box, top the dead left screw, pry the right screw, and then read the table display value at the head of the right screw.

10,Manual turning motor rotation180After the degree, repeat the above steps to read out the table value.

11,Calculationcone double barrel screwDifference of shim thickness.

12,Measurementcone double barrel screwTotal clearance: the left and right screw(No gasket)Top to the distribution box,Place the dial indicator at the small end of the barrel, and put the probe head on either one.cone double barrel screwAdjust the epitope after the head.ToBit. At the same time, pry at the blanking openingcone double barrel screwTo die in the direction of the nose.,Then read the table on the dial indicator.
