The utility model discloses make blade and die surface pressfitting inseparable to make the die surface not produce the paddle -tumble.

Description

A kind of fast rotational underwater cutpellet knife rest

Technical field

The utility model relates to underwater cutpellet technical field.

Background technology

In plastic industry, highly enriched master batch and flexible plastic pelletizing generally use underwater pelletizer.For low viscosity, elastomeric macromolecular material, needing the rubber-plastics material of the molten condition extruded by template to cut into graininess in circulating water, in order to obtain good effect, needing cutting knife and template face to keep close contact.Simultaneously; be vertical due to blade or be fixed on knife rest with certain angle, when pelleter works, material or material grain can be stuck in the angle of blade and knife rest; and blade vertically acts on die face that die face can be made to form paddle-tumble, cause blade and die face can not closely pressing.

Summary of the invention

The purpose of this utility model is to provide a kind of fast rotational underwater cutpellet knife rest, makes blade and die face pressing closely, and makes die face not produce paddle-tumble.

The technical scheme realizing above-mentioned purpose is:

A kind of fast rotational underwater cutpellet knife rest, comprise circular disk body, multiple cutting edge and with described cutting edge spring part one to one;

The multiple grooves with quantity such as described cutting edges are had bottom described disk body;

Each described cutting edge inserts each self-corresponding described groove, and is secured by bolts in described disk body;

The bottom surface of described cutting edge flushes with the bottom surface of described disk body;

The end face of the described cutting edge of one end pushing and pressing correspondence of each described spring part, the other end is fixed on corresponding described groove.

In above-mentioned fast rotational underwater cutpellet knife rest, the cross section parallelogram of described cutting edge.

The beneficial effects of the utility model are: the utility model passes through blade bottom surface and disk body floor design same plane, and simply utilizes spring part, makes cutting edge can keep close contact with die face.Meanwhile, because die face does not produce paddle-tumble, effectively extend the service life of cutting edge and die face.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Refer to Fig. 1, Fig. 2 and Fig. 3, fast rotational underwater cutpellet knife rest of the present utility model, comprise circular disk body 1, multiple cutting edge 2 and with cutting edge 2 spring part 3 one to one.

The multiple grooves 11 with quantity such as cutting edges 2 are had bottom disk body 1.Cutting edge 2, spring part 3 and groove 11 one_to_one corresponding.

Each cutting edge 2 inserts in each self-corresponding groove 11, and is fixed on disk body 1 by bolt 21.The bottom surface of cutting edge 2 flushes with the bottom surface of disk body 1, make like this cutting edge 2 together with disk body 1 with die face parallel contact.

Certain space is had, mounting spring part 3 in this space between the top of cutting edge 2 and the bottom of groove 11.The end face of the cutting edge 2 of one end pushing and pressing correspondence of each spring part 3, the other end is fixed on the bottom of corresponding groove 11.Like this, when cutting edge 2 pressurized, spring part 3 provides a downward pressure, guarantees that cutting edge can keep close contact with die face.

The Cross section Design of cutting edge 2, along rotating clockwise, is become parallelogram by disk body 1.The inclined-plane of cutting edge 2 can produce a downward pressure, utilizes the material of equivalent just can reach better effect when manufacturing cutting edge 2.

Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.

Claims (2)
