Description

Technical Field

[0001] The utility model relates to the technical field of cutters, and more specifically to a cutter for the head of a ceramsite extruder. Background Art

[0002] At the discharge port of the extruder, an extrusion die needs to be set, wherein the extrusion die is provided with a number of small holes or flow channels to disperse the high-temperature melted colloid in the extruder and then extrude it into a number of strips, which are then cut into a number of masterbatch particles by a rotating cutter outside the discharge port. The existing blade cutting is intermittent cutting, and the blade force is periodically distributed, which can easily lead to screw loosening and affect the cutting effect. In severe cases, the cutting may not be in place, and the material cannot be removed, causing long-term blockage, resulting in production losses and poor quality.

[0003] In order to solve the above problems, the utility model patent with publication number CN209478679U discloses a cutting knife device, which replaces the traditional method of fixing the blade with screws by setting an elastic device, and presses the blade in the knife groove by a spherical clamping head so that it cannot be easily loosened. The clamping head is pressed into the knife groove by a spring. Since the end of the clamping head is spherical, the blade can be inserted into the knife groove. When inserting, the blade pushes the clamping head away. After the blade is inserted, it is clamped by several clamping heads and will not be easily loosened. By setting the inclined hole, a rod can be inserted into the inclined hole to move the clamping head, so that the clamping head retracts into the mounting hole, so that the blade can be smoothly inserted into the knife groove.

[0004] However, when the above-mentioned cutter device is actually used, after the cutter cuts the material, some material residues will remain on the surface of the cutter, and the cutter needs to be quickly replaced and cleaned, which may affect the subsequent use of the cutter and reduce work efficiency.
