Description
Technical field
The utility model is specifically related to a kind of novel PVC extruding pelletization cutting off tool structure.
Background technique
Currently, the pelletizing cutter that each PVC extruding pelletization manufacturing enterprise in the pelletizing of PVC extruding pelletization, uses is more
Knife rotates the cutting form of rotation, and is all made of traditional cutting edge roundness perpendicular to the layout of cut direction.And it is such perpendicular to
The cutting edge roundness distribution form of cut direction, replacement cutter operation difficulty is big, time-consuming for adjustment, and cutter is worn in use
It is larger, it is easy to appear cutting tool dulling.More importantly being produced and used perpendicular to the cutting edge roundness distribution form of cut direction
In the process, the phenomenon that material grain being cut into is not easy refrigerated separation, is easy to appear material grain mutual adhesion.Seriously affect the appearance of product
Quality will also directly influence the normal use of product when adhesion phenomenon is serious, thus influence production yield rate or cause to do over again,
So that increasing production cost.
Utility model content
The purpose of the utility model is to provide a kind of novel PVC extruding pelletization cutting off tool structures.
In order to meet above-mentioned purpose, the technical solution that the utility model is taken are as follows: a kind of novel PVC extruding pelletization cutoff tool
Lamps structure, including extrusion die, the center of the extrusion die are equipped with hollow shaft, are installed in hollow shaft by clamp nut
There are several knife rests, cutter blades are installed on knife rest.
Preferably, holddown spring is provided between the clamp nut and knife rest.
Preferably, on the knife rest between the cutting edge of cutter blades and the end face diameter direction of extrusion die at 25 ° ~ 32 °
Angle.
Preferably, one end for being connected with knife rest of the hollow shaft is provided with cooling gas nozzle.
Preferably, the blade lower part of the knife rest is equipped with inflatable mouth.
Preferably, the cutter blades are mounted on knife rest by housing screw.
The utility model has the following beneficial effects: a kind of novel PVC extruding pelletization cutting off tool structure of the utility model, peace
It after being attached to extruding granulator, does not need to increase other any new ancillary equipments for extruding pelletization production line, can make to be granulated and give birth to
The material grain cut off during producing avoids sticking together, to improve product quality and product qualification rate, and makes extrusion die and knife
The service life of tool improves 20%, can be granulated manufacturing enterprise for PVC and save cutter purchase cost.Meanwhile operation of the present invention is easy,
It is easy to use, it is not necessarily to manual intervention after installing and using, the working efficiency of PVC extruding pelletization production, and structure letter can be effectively improved
Single, manufacturing cost is low, long service life.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure: 1. extrusion dies, 2. holddown springs, 3. cooling gas nozzles, 4. clamp nuts, 5. hollow shafts, 6. knife rests, 7. pressures
Tight screw, 8. cutter blades, 9. inflatable mouths.
Specific embodiment
The utility model is described further with working principle with reference to the accompanying drawing:
A kind of novel PVC extruding pelletization cutting off tool structure as shown in Figure 1, including extrusion die 1, extrusion die 1
Center is equipped with hollow shaft 5, passes through clamp nut 4 in hollow shaft 5 and is equipped with several knife rests 6, is equipped with cutoff tool on knife rest 6
Piece 8, cutter blades 8 are mounted on knife rest 6 by housing screw 7, to facilitate the maintenance and replacement in later period；Clamp nut 4
Holddown spring 2 is provided between knife rest 6, so that the cutting edge of cutter blades 8 is mutually close to the end face of extrusion die 1, on knife rest 6
At 25 ° ~ 32 ° angles between the cutting edge of cutter blades 8 and the end face diameter direction of extrusion die 1, hollow shaft is connected with knife rest
One end be provided with cooling gas nozzle 3, the blade lower part of knife rest 6 is equipped with inflatable mouth 9, to extrusion die 1 and is cut using compressed air
Breaking piece 8 passes through cooling gas nozzle 3 and inflatable mouth 9 is cooled down, so as to extrusion die 1 and cutter blades during cutting
The abrasion of 8 cutting edges reduces, and improves mold and cutting-tool's used life, while granular material grain is in dispersion shape and extrusion die
1 is detached from, it is therefore prevented that stick to each other between each material grain of continuous cutting-off, to improve the qualification rate of product quality and product.
The working process of the utility model is as follows: novel PVC extruding pelletization cutting off tool structure is installed to extruding granulator
Afterwards, then by the thermoplastic resin being plasticized from the extrusion in a strip shape of extrusion die 1, pass through the extrusion die 1 rotated clockwise and its
The cutter blades 8 that end face abuts cut off the thermoplastic resin of strip being plasticized, graininess and extrusion die end after cutting
Emaciated face from.
