Cutter structure of a pelletizer

Abstract

This invention proposes a cutting tool structure for a cutting machine, wherein a plurality of blade sets are arranged in a ring on a hollow blade body shell. A wedge-shaped member is used to protrude the blade into the corresponding blade receiving groove, and a fixing member is inserted through the inside of the blade body shell and screwed onto the wedge-shaped member. This prevents the fixing member from being impacted by plastic particles generated during the cutting process, thereby reducing the wear of the fixing member. The wedge-shaped member also improves the convenience of blade replacement and maintenance.

Claims

1. A cutting tool structure for a cutting machine, comprising: a tool body housing having a plurality of tool sets arranged in a ring around its outer side; a hollow body being provided on an inner side of the tool body housing; a plurality of fixing holes being provided on the inner side corresponding to the tool sets; each of the tool sets comprising: two receiving grooves; a fixing groove being clamped between the two receiving grooves; two blade members being individually protruding from the receiving grooves; a wedge-shaped member being protruding from the fixing groove and used to clamp each of the two blade members between the wedge-shaped member and the tool body housing; a screw hole being provided on an inner side of the wedge-shaped member; and a fixing member being correspondingly provided in one of the fixing holes and for screwing the wedge-shaped member.

2. The tool structure as described in claim 1, wherein the tool body housing and the wedge-shaped components are selected from stainless steel materials with low thermal expansion or corrosion resistance.

3. The tool structure as described in claim 1, wherein the tool sets are arranged at equal intervals along the outer side of the tool body housing.

4. The tool structure as described in claim 1, wherein the wedge-shaped member is provided with a first contact surface that contacts one of the two cutting blades and a second contact surface that contacts the other of the two cutting blades.

5. The tool structure as described in claim 1, wherein the wedge and the fixing groove are provided with a gap space.

6. The tool structure as described in claim 1, wherein the width of one of the tool sets is the same as the width of one of the tool body housings.

7. The tool structure as described in claim 1, wherein the two tool grooves and the fixing groove are provided with two openings at their respective ends.
