Embodiment Construction

[0028] figure 1 shows a particular embodiment of a flaker as a ring flaker for flakes or comminution of wood, in particular for the production of wood chips or similar materials. Arranged in the housing 1 is a rotating (outer) knife ring 2 on the one hand and an impact wheel 3 rotating inside the knife ring on the other hand. The knife ring 2 and the impact wheel 3 are driven via suitable shafts. Details are not shown in the figure. Typically, the knife ring 2 on the one hand and the impact wheel 3 on the other are counter-rotating. figure 1 A ring flaker is shown, the front of the housing of which is open, so that in particular the knife ring 2 and the impact wheel 3 can be seen inside the housing. Wood is supplied as bulk material, for example in the form of wood chips. This bulk material enters the interior of the ring flaker via an upper conveying chute 4 and the corresponding front deflection 5 , and thus enters the inner chamber formed in the interior of the impact w...

Abstract

The method involves fastening multiple knife holders (9) at a rotating knife ring (2). Knives (6) are held at the holders by clamping. The knives to be sharpened are advanced in / at the holders without releasing the clamping, and subsequently ground by a grinding device i.e. belt grinding device, in an advanced position. Clamping plates of the holders are connected with holding plates by clamping screws (10). The knives are fixed between the holding plates and the clamping plates by the clamping screws. The knives are polished in the advanced position upto a preset management measure. An independent claim is also included for a device for resharpening knives of a knife ring flaker.

Description

technical field [0001] The invention is a method for grinding, especially regrinding, of knives of a ring-type flaker. On this ring-type flaker, a plurality of tool holders are fixed on the knife ring. At least one tool is respectively clamped by the clamping mechanism on the tool holder, and the tool to be ground on the tool holder is pushed forward, and then it is ground by the grinding device at the position where it is pushed forward Background technique [0002] Ring flakers are used to produce material such as wood chips, which are used to make wood boards such as wood chip pressed boards and the like. Logs are usually supplied as bulk material, for example in the form of wood chips. Such a ring flaker has a knife ring on which several knives are fixed on / in the knife holders. The tool holder is, for example, composed of a clamping plate and a clamping plate connected to the clamping plate via at least one clamping bolt, and the tool is fixed to the clamping plate an...
