The granulating mechanism 100 includes a mold roll body 10 and a replacement cutter 15, and the replacement cutter 15 is detachably connected to the outer peripheral surface of the mold roll body 10.

Since the existing granulating mechanism is integrally formed, when the granulating machine has been in operation for a period of time, the granulating mechanism is more or less partly worn. When the tooth surface of the granulating mechanism is worn out, the entire assembly needs to be replaced. Disassembling the pellet machine equipment is inconvenient to replace and affects production efficiency.

In the granulating mechanism 100 provided in this embodiment, by detachably installing the replacement cutter 15 on the outer peripheral wall of the die roll body 10, when a replacement cutter 15 of the granulating mechanism 100 is worn or damaged, only the corresponding replacement needs to be replaced The cutter 15 is sufficient, and the entire granulating mechanism 100 can be replaced without dismantling the granulator equipment, which is convenient for replacement and reduces the cost.

In addition, the tooth surfaces at the junction of two adjacent replacement tools 15 smoothly transition.

2 is a schematic diagram of the mold roll body 10 in FIG. 1, and FIG. 3 is a schematic diagram of the replacement cutter 15 in FIG. 1, please refer to FIGS. 2 and 3.

The outer peripheral surface of the die roll body 10 is provided with a threaded hole 12. Correspondingly, the replacement tool 15 is provided with a through hole 17 corresponding to the threaded hole 12 in the radial direction. The through hole 17 is penetrated by a bolt 18 and then locked to the thread. The hole 12 is used to connect the replacement cutter 15 and the die roll body 10 fixedly.

Since the outer peripheral surface of the replacement tool 15 is a uniformly arranged tooth-like structure, normal operations can be performed by penetrating the bolt 18 through the through hole 17, so optionally, the through hole 17 is a countersunk hole, and the bolt 18 is penetrated The through hole 17 is threadedly connected with the threaded hole 12, and the head of the bolt 18 does not protrude from the outer peripheral surface of the replacement tool 15.

The die roll body 10 and the replacement tool 15 are not only fixedly connected by the above-mentioned fasteners, but also can be connected through the first plug-in part 11 and the second plug-in part 16 on the basis of the fixed connection of the above-mentioned fasteners. , The pre-positioning before installation and fixation is realized, so that the mold roll body 10 and the replacement cutter 15 are fixed as a whole.
