Problems solved by technology

[0005] However, this invention still has some disadvantages, the two clamping elements have to be inserted from both sides in order to guarantee a constant clamping force distribution, sufficient clamping force and stability
This makes both the production of the rotor body and the assembly of the cutting blades to the rotor complex and expensive

Embodiment Construction

[0042] figure 1 One embodiment of a granulation device 10 is shown. For better illustration, the device is shown with an open top, referred to below as the cutting chamber baffle 11 . At its front end, the pelletizing device 10 has a housing flap 12 through which plastic fiber strands (not shown in the figures) are fed into an inlet chute 14 . Next, the plastic fiber strand is further drawn into the two feed rollers 16, 28 of the pelletizing device. The lower feed roller 16 is mounted on a bearing 17 and is driven by a gear 19 and a feed roller driver 18 . The upper feed roller 28 is mounted on a bearing 29 attached to the cutting chamber baffle 11 and is driven by a gear 31 and a feed roller driver 30 . After passing the feed rollers 16 , 28 , the plastic fiber strands reach the cutting rotor 20 mounted on bearings 21 and driven by a gear 23 and a rotor drive 22 . The cutting rotor 20 has a cutting blade 24 disposed on its outer peripheral surface 26, which cuts the plast...

Abstract

The invention relates to a granulation device for cutting plastic wire into granules, comprising: a cutting rotor driven by a drive system; and cutting blades distributed on the outer periphery of the cutting rotor, the cutting blades comprising: The blades are placed in grooves in the body of the cutting rotor; each cutting blade has a recess parallel to the cutting edge, covered by one of the grooves, to receive and interact with a clamping device, which is held by Clamped in a reverse recess of the cutting rotor body; wherein each clamping device includes a clamping sleeve and an expansion device, the clamping sleeve can be extended radially, and the expansion device can make the clamping sleeve at least along widened in the radial direction. In the groove, only one clamping sleeve is provided for each cutting blade; the recess of the cutting blade extends at least from one flat end of the cutting blade to the other flat end close to the cutting blade; Reverse the outer contour inside the recess.

Description

technical field [0001] The invention relates to a granulation device with a cutting rotor. Background technique [0002] Pelletizing devices with cutting rotors for cutting plastic fibers wire into pellets are widely used in combination with plastic extrusion devices. Typically, a cylindrical cutting rotor equipped with cutting blades rotates at high speed and provides plastic pellets for further processing. The cutting blades are distributed over the entire circumference of the rotor and are connected to the rotor in an operationally safe and low-wear manner. [0003] In the above solution, the cutting blade is welded to the surface groove of the rotor body. In this regard, it has been proposed to clamp the blade to the groove in a different way, for example mechanically or hydro-mechanically, which would allow for easier blade replacement. [0004] US patent 6386469B1 discloses a granulation device with a cutting rotor and blades which are clamped by means of grooved an...
