Abstract
The invention provides a structure of a mixing section and a kneading section of an extruder, which comprises a cylinder and a screw. The cylinder is provided with a shell and dowels. The screw is provided with a screw shaft and vanes. The dowels are vertically fixed on the inner circumference of the shell of the cylinder in three lines. The vanes are fixed on the screw shaft in three lines. The dowels and the vanes are axially and radially arranged in a staggered manner uniformly. The dowels in the mixing section are shorter than those of the kneading section. The vanes are crescent. The screw shaft is provided with a blade with an axial blade. The blade and the vanes are arranged in a staggered manner circumferentially. The structure of the mixing section and the kneading section of the extruder can cut and smash materials adequately by match of the cylinder and the screw. The smashed materials enter the kneading section. Due to the special structure of the kneading section, the smashed materials are milled adequately, and finally the product extruded is finer and better in quality.
Description
Technical field
The present invention relates to a kind of extruder mixing section and kneading block structure, be the plastics machinery field.
Technical background
The structure of existing screw extruder mixing section and kneading block is generally all simpler, and machine tube inner wall is smooth, and screw thread also is the shape of rule generally on the screw rod, but the product quality of this kind Screw Extrusion is not fine.Because material passes through first mixing section in machine barrel, pass through again kneading block, no matter existing extruder is mixing section or kneading block, and its effect of extruding is not fine, and the quality of extruded product is also just very coarse.
Summary of the invention
In order to overcome above problem, the invention provides a kind of extruder mixing section and kneading block structure, structure can fully be cut off material and pulverize by machine barrel and cooperating of screw rod, particle enters kneading block again, because the special construction of kneading block, particle is fully ground, the product quality of finally extruding is thinner better again.
For solving above technical problem, the invention provides following technical scheme: a kind of extruder mixing section and kneading block structure, described extruder mixing section and kneading block structure comprise machine barrel and screw rod, and described machine barrel has shell and pin, and described screw rod has screw shaft and blade;
Described pin is divided into three row and is vertically fixed on machine barrel shell inner periphery;
Blade is divided into three row, is fixed on the screw shaft;
Described pin and blade axially and radially are being interlaced arrangement.
Further, described mixing section pin is shorter than the length of kneading block pin.
Further, described blade is shaped as crescent.
Further, have the blade of axial blade on the described screw shaft, blade and blade circumferentially are crisscross arranged at screw shaft.
This extruder mixing section and the kneading block structure that the present invention relates to by the improvement of machine barrel and screw rod part, can be finished the target of improving the quality of products.

The 1-machine barrel; The 12-pin; The 9-pin; The 13-blade; The 14-blade; The 7-screw rod.
The specific embodiment
Shown in Fig. 1-2, be a kind of extruder mixing section provided by the invention and kneading block structure, extruder mixing section and kneading block structure comprise machine barrel 1 and screw rod 7, and machine barrel 1 has shell and pin 12, and screw rod 7 has screw shaft and blade 14; Pin 9 is divided into three row and is vertically fixed on machine barrel shell inner periphery; Blade 14 is divided into three row, is fixed on the screw shaft; Pin 12 axially and radially is being interlaced arrangement with blade 14.
Mixing section pin 12 is shorter than the length of kneading block pin 9.
Blade 14 be shaped as crescent.
The blade 13 that has axial blade on the screw shaft, blade 13 and blade 14 circumferentially are crisscross arranged at screw shaft.
The specific embodiment of the present invention does not consist of the restriction to the application's scope; every within the spirit and principle of the present invention design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within protection scope of the present invention.
