Description
Technical field:
The present invention relates to a kind of plastic grain cutting machines, belong to plastic material production equipment technology.
Background technique:
Strip or sheet plastic cement are cut into the equipment of granular material or the general name of machine by plastic grain cutting machine.In plastics
In grain production process, it is necessary first to heat plastic pellet by extruder and melt and squeeze out strip, then pass through cooling trough
Cooling down operation is carried out, solidifies material strip, material strip after cooling is finally made to be granulated into certain specification size by pelleter
Particle.In existing pelleter production process, material strip passes through between traction roller and rubber roller, then, the shape by cutter cutting
At the slice of certain size, but since many plastic grains cannot cool down thoroughly in cooling trough, cause to cut backward modeling
Material particle is easy to happen adhesion, and the material strip after cooling trough, does not evaporate completely due to carrying a large amount of moisture content,
Cutter is entered back into, cutter is caused to get rusty easily, service life reduces.
Summary of the invention
It, can during pelletizing the purpose of the present invention is providing a kind of plastic grain cutting machine in view of the above problems
It effectively prevent plastic grain to stick together, improves product qualification rate, and be conducive to extend the service life of cutter.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of plastic grain cutting machine, including being successively set on the cooling water tank of extrusion head discharge port one end, traction roller group, cutting
Knife group, the traction roller group include upper traction roller and lower traction roller, and one group of width is provided on the lower traction roller less than material strip
The water guide groove of width is provided with cooling blower, the air outlet of the cooling blower between the traction roller group and the cutter
It is not more than 15 ° with the angle of horizontal direction.
The plastic grain cutting machine, the cooling blower are connected with ventilating duct, are provided with spiral shell inside the ventilating duct
Revolve shape guide plate.
The plastic grain cutting machine, the width between two neighboring water guide groove are 1.2-1.5 times of material strip width.
The plastic grain cutting machine, the cutter group includes lower fixed tool apron, the incision that is mounted on lower fixed tool apron
Knife, the lower fixed tool apron top are provided with movable tool apron, are equipped with upper cutter on the upper movable tool apron, described is upper
Movable tool apron connects up and down motion driving device.
The plastic grain cutting machine, the up and down motion driving device include the branch connecting with the upper movable tool apron
Bar, the strut pass through guide cylinder and are connect with connecting rod by pin shaft, one end of the other end connection rocking bar of the connecting rod, institute
State the other end connection electric motor of rocking bar.
The utility model has the advantages that
The present invention recycles cooling blower to be blowed, a side by being provided with one group of water guide groove on lower traction roller
Face achievees the purpose that cooling, on the other hand hangs over the droplet in material strip under the action of the forces of the wind from water guide groove from outflow, avoids
Material strip carries a large amount of moisture content by causing to corrode to cutter during cutter.
