Description

Technical Field

[0001] The utility model relates to the technical field of granulators, and specifically relates to a quick and precise adjustment granulator tool rest. Background Art

[0002] A granulator is a device that rolls and presses powder raw materials into granular form; the main component of the granulator is a roller press, which uses a tire hydraulic press as a power source, and drives a reduction motor to rotate a ring die through a variable frequency speed regulation motor, so as to achieve the compression and forming of powder raw materials. The granulator mainly consists of a feeding, stirring, granulating, transmission and lubrication system, etc. The raw materials after being crushed and mixed are put into the granulator. The raw materials are extruded in the granulator and then extruded out of the die to form long strip-shaped particles, and are cut off by a cutting tool beside the extrusion die. Specifically, after the raw materials are mixed well, they are extruded into the ring die, and then rotate with the ring die, and are thrown out from the ring die outlet under the action of centrifugal force, and are cut off after colliding with the cutting knife.

[0003] Most of the existing cutting knives of granulators are installed in fixed positions, and the distance between the cutting knife and the surface of the ring die is fixed, resulting in a single length of the particles produced by the granulator. In addition, the fixed position of the cutting knife makes the cutting knife vulnerable to the collision and friction of material particles, and the contact part of the particles is worn. The uneven cutting edge of the cutting knife causes the particles to be of different lengths, affecting the production quality. Content of the Utility Model

[0004] The purpose of the utility model is to provide a quick and precise adjustment granulator tool rest to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a quick and precise adjustment granulator tool rest, including a cutting knife rod. The cutting knife rod is a solid cylinder. A section of rack is arranged on the outer circumferential surface of the right side of the cutting knife rod. A gear meshing with the rack is arranged on the rack. A tooth shaft is fixedly installed in the middle of the gear. One end of the tooth shaft is provided with a manual driving wheel, and the other end of the tooth shaft is installed in a tooth shaft fixing seat. The tooth shaft fixing seat is installed on the granulator housing; the leftmost end of the cutting knife rod is fixedly installed with a tool rest, and a cutting blade is arranged on the tool rest. A cutting knife seat is sleeved in the middle of the cutting knife rod. A first locking ring is sleeved on the outer circumferential surface of the end of the cutting knife seat far away from the tool rest. A second locking ring is arranged on the top surface of the cutting knife seat. A key pin is arranged in the second locking ring, and the side end surface of the key pin fits the tooth groove end surface of the rack.

[0006] Preferably, a limiting pin is longitudinally arranged at the rightmost side of the cutting knife rod, and the limiting pin is fixed across the cutting knife rod.

[0007] Preferably, a handle is arranged on the outer side surface of the driving wheel.

[0008] Preferably, a first handle is provided on the first locking ring, and a second handle is provided on the second locking ring.

[0009] Preferably, a rectangular fixing plate is connected to the side of the cutter holder close to the tool rest by bolts. Positioning holes are provided at the four corners of the fixing plate, and bolts are arranged in the positioning holes to fix the fixing plate on the granulator housing.

[0010] Preferably, the position where the rack is provided on the cutter bar is replaced with a sliding groove, a key bar with a shape and size that fits is installed in the sliding groove, and one end of the key bar is fixed inside the second locking ring.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model provides a structure for quickly and accurately adjusting the distance between the tool rest and the ring die. By reciprocating movement of the gear on the rack, the position of the cutter bar is adjusted, thereby changing the distance between the blade and the ring die, enabling the cutter to evenly cut the material and meeting the production requirements for different lengths of particles; reducing the number of blade replacements and improving the yield.
