Description

A kind of comminutor

Technical field

The utility model relates to a kind of comminutor and improve invention, particularly be a kind of comminutor that waste or used plastics processing is reclaimed that is used for.

Background technology

When the extrusion screw rod of plastic granulator is worked, need the plastic raw materials of wedging certain specification, these raw materials need pass through the plastics disintegrating apparatus and pulverize; Therefore, every comminutor all need dispose one or several pulverizers and process raw material for it, so; Not only power consumption is big; And increase equipment maintenance cost and staff, increase production cost greatly, and increasing of equipment will certainly take plant area.At present, existing plastic granulator is horizontal, and the hopper of horizontal comminutor is vertical with extruding screw, needs slowly to feed in raw material, and not so can cause charging aperture to stop up; And the screw rod of horizontal comminutor is long, has 1 meter approximately, and its rotating speed is low; Raw material need utilize heater to melt, thereby the floor space of horizontal comminutor is big, and warm-up time is long; Power consumption is big; Cost is high, and plastics are just big through melting for a long time the physical property and the molecular structure destruction of plastics, and the color change of finished product just greatly.

Summary of the invention

In view of the existing technical problem of background technology, the utility model technical problem to be solved provides that a kind of floor space is little, electric energy loss is little, production cost is low, quality of finished product good, and integrates the comminutor of pulverizing.

In order to solve the problems of the technologies described above, the utility model adopts following scheme to realize: this kind comminutor includes support, hopper, screw rod, extrusion die and motor; Said screw rod is connected with motor, and said extrusion die is provided with cutting knife outward, and said cutting knife is installed on the cutterhead; Said cutterhead is connected with a drive of motor; It is characterized in that being provided with screen pack in the said hopper, the top of said screen pack is provided with reducing mechanism, and said reducing mechanism includes the pulverizing cutter.

Said pulverizing cutter includes stationary knife and moving knife, and said stationary knife is installed on the hopper, and said moving knife is installed on the knife rest, and said knife rest is connected with motor.

Said screw rod is vertical with support to be provided with, and said screw rod stretches in the hopper, and said extrusion die is arranged on the lower end of screw rod.

The length of said screw rod is 150mm-200mm.

The utility model is pulverized raw material through pulverizing cutter, and through screen pack the plastics after pulverizing is screened, and the raw material through screen pack is pushed by screw rod, and is extruded by extrusion die, by cutting knife it is cut into graininess; Then do not proceed to pulverize, until passing through screen pack by pulverizing cutter through the raw material of screen pack.The utility model integrates pulverizing, granulation, and kwh loss is little, personnel operation is few, floor space is again little, not only reduces production costs greatly, has also improved production efficiency, has brought great economic interests to enterprise; Said screw rod vertically is provided with, and has reduced floor space, and said screw rod stretches in the hopper; Raw material after the pulverizing is directly pushed by screw rod, because spiro rod length is short, rotating speed is fast, the temperature that screw rod and plastic friction produce makes plastics reach fusing point fast; And fricative temperature very evenly, thereby destructive little to plastics, and the finished color variation is little; Better quality need not to heat, thereby energy loss is little; Cost is low, and because charging aperture is big, has avoided the charging aperture blocking problem to take place.

Description of drawings

Further describe the operation principle and the relevant details thereof of the utility model below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of the utility model.

The specific embodiment

With reference to accompanying drawing, this kind comminutor includes support 6, hopper 11, screw rod 1, extrusion die 5 and motor 13; Said screw rod 1 and support 6 vertical settings, an end of said screw rod 1 stretches in the hopper 11, and the other end is connected with motor 13; The length of said screw rod 1 is 150mm-200mm; Spiro rod length in this scope can quick rotation, can fully push again, and screw rod 1 makes plastic melt with the temperature that plastic friction produces; Said extrusion die 5 is arranged on the lower end of screw rod 1, and said extrusion die 5 is provided with discharge opening 4, and raw material fusing back is extruded by discharge opening 4; Be provided with cutting knife 3 outside the said extrusion die 5, said cutting knife 3 is installed on the cutterhead 2, and a said cutterhead 2 and a motor 12 are in transmission connection; Said cutting knife 2 is along with cutterhead 2 rotations, and every process discharge opening 4 just cuts off the plastics of extruding, and can be provided with many cutting knife 3 on the said cutterhead 2; The utility model is provided with two cutting knifes 3; Therefore, cutterhead 2 whenever circles, and the plastics that discharge opening 4 is extruded are cut off twice; Be provided with screen pack 10 in the said hopper 11, the top of said screen pack 10 is provided with reducing mechanism, and said reducing mechanism includes the pulverizing cutter.Said pulverizing cutter includes stationary knife 7 and moving knife 8; Said stationary knife 7 is installed on the hopper 11; Said moving knife 8 is installed on the knife rest 9, and said knife rest 9 is connected with screw rod 1, drives knife rest 9 by screw rod 1 and rotates; Moving knife 8 moves with respect to stationary knife 7, and the raw material in the hopper is pulverized under the cutting of moving knife 8 and stationary knife 7.

During the work of this machine, raw material is got into by hopper, and motor 13 starts; Driving screw rod 1 rotates; Rotate at the drive lower slide 9 of screw rod 1 and the moving knife on the knife rest 8, moving knife 8 rotations cooperate with stationary knife 7 cuts the raw material in the hopper, is cut raw material after the pulverizing through screen pack 10 filtrations; The raw material of small dimension is pushed by 1 pair of raw material of screw rod through the below of screen pack 10 entering hoppers 11; The raw material through screen pack 10 does not then continue to be pulverized, until the size that reaches regulation; Because the fast rotational of screw rod 1; Raw material with screw rod 1 friction, the process that is extruded in reach fusing point fast; And extrude by the discharge opening 4 of the extrusion die 5 of screw rod lower end, the outer cutting knife of extrusion die 5 this moment is along with cutterhead 2 rotations, when cutting knife 3 is whenever passed by discharge opening 4 places; The plastics of extruding just are cut off, graininess.
