3) Mixing and crushing: when the mixing roll is running, the friction force produced by the surface of the rotating stirring paddle and the pigment and the dispersing agent makes the pigment and the dispersing agent move tangentially along the paddle surface, simultaneously the pigment and the dispersing agent are thrown to the inner wall of the mixing chamber under the action of centrifugal force, rise along the wall surface, fall back to the center of the stirring paddle under the action of gravity after rising to a certain height, and then are thrown up, the pigment and the dispersing agent are in a continuous spiral up-and-down movement state due to the combination of the tangential movement and the rising movement, the pigment and the dispersing agent are in a continuous spiral up-and-down movement state due to the high rotating speed of the paddle, usually 600r/min or 1000r/min, the rapidly moving pigment and the dispersing agent collide and rub with each other, so that lumps are broken, the temperature of the pigment and the dispersing agent is raised, and the cross mixing is carried out simultaneously, the flow state of the pigment and, The mixing action is accelerated.
4) Melting and processing: in the melting process, the resin mass rolls forwards along the screw groove under the combined action of the cylinder and the screw, and is melted, and when the fullness is larger, the resin mass is not a two-phase mass.
5) Cooling and pelletizing: after resin and dye enter the screw from the hopper, the resin and dye are conveyed forwards under the action of the rotating screw through the friction action of the inner wall of the material cylinder and the surface of the screw, loose solid granules (or powder) fill the screw grooves in the feeding section of the screw, the material starts to be compacted along with the continuous conveying of the material, after the material enters the compression section, the resin and dye gradually form high pressure and are further compacted due to the gradual shallow depth of the screw grooves and the resistance of a machine head, meanwhile, under the action of internal friction shearing heat generated by the heating outside the material cylinder and the strong stirring, mixing and shearing friction of the screw and the inner surface of the material cylinder on the material, the temperature of the resin and the dye is continuously increased, the temperature of the resin and the dye reaches the melting point at a certain point of contact with the material cylinder, the resin and the dye start to be molten, the material continues to be heated along with the conveying of the material, the quantity of the molten material is gradually, at the end of the compression section, all the materials are converted into viscous state, but the temperature of each point is not uniform yet, the homogenization effect is relatively uniform through the homogenization section, the molten materials are extruded into a machine head by a rear screw rod in a quantitative, constant-pressure and constant-temperature mode, a die in the machine head is a molding part, the materials pass through the die to obtain a geometric shape and a size of a certain cross section, and then the solid color master batch can be obtained through cooling and shaping and other procedures.
The invention has the beneficial effects that: in the melting process, the resin group is at the barrel, under the combined action of screw rod, the spiral groove rolls forward along the one side, the one side melting, when the fullness is great, the resin group no longer is individual double-phase material group, through adopting double helix melting processing, thereby heating effect has been improved, the mode of dual heating, heating melting's sufficiency has been guaranteed, and then not only improved work efficiency but also effectively promoted heating effect, through make collision each other between pigment and dispersant fast, the friction, make the block piece broken, pigment and dispersant temperature rise, cross mixing carries out simultaneously, the baffling board in the mixing chamber has disturbed pigment and dispersant flow state, make pigment and dispersant form irregular motion, and form the swirl near the baffling board, mixing action has been accelerated, the practicality of this device has been improved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
