Abstract

The utility model belongs to the technical field of plastic machinery, which is used for the recovery processing of waste and used plastics and leftover bits and pieces. The utility model aims to save energy, decrease vibration, reduce noise, break thick plates and blocky plastics, and enhance production efficiency to dupplement the deficiency of existing machine models. Adopted fixed cutters (11) and rotary cutters (12) are large in number and small in size, and each cutter has two edges. The fixed cutters (11) are divided into two rows and symmetrically installed on the connecting points of the front and the back walls of an upper box body (3) and a lower box body (2). The rotary cutters (12) are spirally distributed and installed on a cutter frame (10). The resistance of cutting and crushing is small, the cutting movement is basically continuous, so the purposes of the design are achieved.

Description

Multiple cutter power saving plastic pulverizer

This utility model belongs to the plastics machinery technical field, is applied to the recovery processing of waste or used plastics, corner blanking.

At present, the plastic breaker that each factory produces, its cutter are all 5 of 5 or spreadings, wherein 3 of rotating knifes, 2 of dead knives, the few sword of cutter is long, be interrupted cutting, has that resistance is big, energy consumption is high, vibration is strong, noise is big, productivity ratio is low and can not broken slab and the bulk shortcoming of expecting.

The purpose that designs this utility model is to overcome the deficiency of existing type, provides that a kind of energy consumption is low, noise is little, productivity ratio is high and can broken slab and the plastic breaker of block material.

The contrast accompanying drawing is illustrated concrete structure of the present utility model and operation principle.

Accompanying drawing is a structure diagram of the present utility model, and Fig. 1 is that front view, Fig. 2 are that left view, Fig. 3 are vertical views.

This utility model is assembled by parts such as support (1), lower box (2), upper box (3), hopper (4), motor (15), belt pulley (13), cutter shaft (9), knife rest (10), rotating knife (12), dead knife (11), flying wheel (8), material screen (5), discharging dustpans (7).

Support (1) back fixed electrical machinery (15), the inner discharging dustpan (7) of installing is fixed together with lower box (2) above. Material screen (5) is installed in lower box (2) bottom, and top and upper box (3) are fixedly connected. Between upper box (3) and the lower box (2) cutter shaft (9) is installed, the upper immovable support (10) of cutter shaft (9), rotating knife (12) distributes in the shape of a spiral and is installed on the knife rest (10). Two row's dead knife (11) symmetries are installed in upper box (3) and lower box (2) front and rear wall connection place. Cutter shaft (9) one end fast pulleies (13), an end is flying wheel (8) fixedly. Hopper (4) is arranged on the upper box (3).

Motor (15) drives cutter shaft (9) by motor pulley (16), V belt (14), belt pulley (13), thereby drives knife rest (10) rotation.Material by hopper (4) feeding, the big cutter (12) that is rotated is squeezed on upper box (3) wall and to its cutting, the little back row's dead knife (11) that is brought to is located to shear, after the material that is cut enters lower box (2), reach promptly falling into outside discharging dustpan (7) and the outflow machine by material screen (5) of specification requirement, the cutter (12) that will be rotated that does not reach specification requirement scrapes front-seat dead knife (11) and locates further shearing.

The rotating knife (12) of novel employing is arranged this reality and dead knife (11) quantity is many, volume is little and a cutter two swords, and rotating knife (12) shape in the shape of a spiral distributes and is installed on the knife rest (10).Have only minority rotating knife (12) work to aniseed extruding cutting the time, each and dead knife (11) has only a slice rotating knife (12) work when shearing, and therefore, resistance is little, energy consumption is low, and the bulk material can be shredded gradually; During work, cutting is continuous substantially, so vibration is little, noise is low; Owing to a cutter two swords, the long sum of actual cut sword has the much longer of type now, thereby has improved productivity ratio again.

The specification of this utility model can be designed to seriation by the GB requirement, with this regeneration product as plastic breaker.

Claims

A kind of multitool energy-saving plastic disintegrating machine that is used for waste or used plastics, corner blanking recovery processing, it is characterized in that: the dead knife of employing (11) and rotating knife (12) quantity is many, volume is little and a cutter two swords, dead knife (11) divides two row's symmetries to be installed in upper box (3) and lower box (2) front and rear wall connection place, and rotating knife (12) shape in the shape of a spiral distributes and is installed on the knife rest (10).
