Description
Technical field：
The present invention relates to a kind of plastic grain cutting machines, belong to plastic material production equipment technology.
Background technology：
Strip or sheet plastic cement are cut into the equipment of granular material or the general name of machine by plastic grain cutting machine.It is given birth in plastic grain
During production, it is necessary first to heat plastic pellet by extruder and melt and squeeze out strip, then be carried out by bosh
Cooling down operation allows material strip to cure, and material strip after cooling is finally made to pass through the particle that pelleter is granulated into certain specification size.
In existing pelleter production process, material strip passes through between carry-over pinch rolls and rubber roller, then, is cut off by cutter and forms one
The slice being sized, but since many plastic grains cannot cool down thoroughly in bosh, cause to cut backward plastics
Grain is easy to happen adhesion, and the material strip after bosh, is not evaporated totally due to carrying a large amount of moisture content, then into
Enter cutter, cutter is caused to get rusty easily, service life reduces.
Invention content
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 conducive to the service life of extension cutter.
Above-mentioned purpose is achieved through the following technical solutions：
A kind of plastic grain cutting machine, including it is successively set on the cooling water tank, traction roller group, cutter of extruder head discharge port one end
Group, the traction roller group include upper carry-over pinch rolls and lower carry-over pinch rolls, and it is wide less than material strip that one group of width is provided on the lower carry-over pinch rolls
The water guide groove of degree, is provided with cooling blower between the traction roller group and the cutter, the air outlet of the cooling blower with
The angle of horizontal direction is not more than 15 °.
The plastic grain cutting machine, the cooling blower are connected with ventilating duct, spiral shell are provided with 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 include lower fixed tool apron, the incision 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 being connect with the upper movable tool apron
Bar, the strut are connect with connecting rod by axis pin across guide cylinder, one end of the other end connection rocking bar of the connecting rod, institute
State the other end connection electro-motor of rocking bar.
Advantageous effect：
The present invention recycles cooling blower to be blowed, on the one hand reaches by being provided with one group of water guide groove on lower carry-over pinch rolls
To the purpose of cooling, the droplet in material strip is on the other hand hung under the action of the forces of the wind from water guide groove from outflow, avoids material strip
A large amount of moisture content is carried by causing to corrode to cutter during cutter.
