Description

A kind of metal pulverizer

Technical field

The utility model relates to a kind of pulverizer, relates in particular to a kind of metal pulverizer.

Background technology

The metal pulverizer mainly solves the bulk iron filings that produce in the process of metal working can't place problem, and borings can't pan feeding before briquetting problem, as shown in Figure 1, in existing metal pulverizer, adjacent moving knife is staggeredly placed on two main shafts, and motor is through the turbine and worm transmission, drive the moving knife rotation on the main shaft, the main axis rotation direction is inside rotation, and borings is cut between moving knife, cuts, tears, drawn, crushing metal or nonmetal smear metal.Existing metal is pulverized facility following shortcoming: because the zone of the moving knife between two main shafts cutwork only, operating efficiency is lower, and the gap between the moving knife is very little, under the situation that a large amount of borings pour in, very easily make moving knife stuck, after machine is stuck, can not realize counter-rotating automatically, burn motor easily; The cutter material is the T10 carbon tool steel, and is shock-resistant poor, the cutter that easily jumps, and cutter life is short, and the comminuted material scope is little; Main shaft and moving knife adopt flat key to be connected, and when cutter repeatedly during rotating, main shaft key is easy to wear, become flexible, even feather key; The main shaft material is 45 steel, and toughness is relatively poor; Adopt the control of manual pushbutton formula, automaticity is low, and labor strength is big, inefficiency; As shown in Figure 3, existing moving knife outer rim is that symmetry is fan-shaped, and stock-removing efficiency is low.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of high efficiency is provided, and the comminuted material scope is big, the metal pulverizer that reliability and automaticity are high.

Technical solution of the present utility model is: a kind of metal pulverizer, comprise moving knife, front housing, spacer ring, side housing, the 1st main shaft, the 2nd main shaft are installed on the side housing, moving knife is installed on the 1st main shaft and the 2nd main shaft, be provided with spacer ring between the adjacent moving knife, it is corresponding with the moving knife on the 2nd main shaft to be positioned at the 1st main shaft, submit for the 1st secondary cutter and the 2nd secondary cutter are installed at the front housing, the outer edge surface of moving knife is corresponding with the outer edge surface of the 2nd secondary cutter, and the side of moving knife is corresponding with the side of the 1st secondary cutter.

As improvement, the outer rim of described moving knife is a zigzag.

As improvement, described moving knife adopts the 6CrW2Si steel alloy.

As improvement, described the 1st main shaft and the 2nd main shaft are six prisms.

As improvement, described the 1st main shaft and the 2nd main shaft adopt the 40Cr steel.

As improvement, adopt PLC electrical autocontrol system.

Technique effect of the present utility model is: the utility model main axis rotation direction is to inner rotary, utilize between moving knife and the secondary cutter and cut, no matter scrap rate what, stuck phenomenon can not appear in machine easily, and two groups of moving knife are respectively to the both direction rotation, and crush efficiency doubles.The utility model cutter material adopts the 6CrW2Si steel alloy, and it is long to have a life-span, is difficult for the advantage of spring cutter, and can pulverizes various borings, waste material and pop can etc., and the comminuted material scope is big.The utility model main shaft adopts six prisms to be connected with the moving knife mesopore is adaptive, connects to replace flat key, avoids occurring easy to wear, the loosening or feather key phenomenon of main shaft key, and main shaft adopts 40Cr steel, good toughness.The utility model moving knife outer rim adopts zigzag, stock-removing efficiency height.The utility model adopts PLC electrical autocontrol system, and the automaticity height can be realized automatic rotating, avoids motor to burn out, and labor strength is low, high efficiency.

The specific embodiment

Be elaborated below in conjunction with drawings and Examples.

As Fig. 2 and shown in Figure 4, a kind of metal pulverizer of the utility model, comprise moving knife 1, front housing 4, spacer ring 7, side housing 6, the 1st main shaft the 8, the 2nd main shaft 9 is installed on the side housing 6, moving knife is installed on the 1st main shaft 8 and the 2nd main shaft 9, be provided with spacer ring 7 between the adjacent moving knife, the moving knife that is positioned on the 1st main shaft 8 and the 2nd main shaft 9 is corresponding one by one, the 1st secondary cutter 2 and the 2nd secondary cutter 3 alternately are installed on front housing 4, the outer edge surface of moving knife 1 is corresponding with the outer edge surface of the 2nd secondary cutter 3, and the side of moving knife 1 is corresponding with the side of the 1st secondary cutter 2.The outer rim of described moving knife 1 is a zigzag.Described moving knife 1 adopts the 6CrW2Si steel alloy.In the 1st main shaft 8 and the 2nd main shaft 9, the part that combines with moving knife is six prisms, and the moving knife mesopore is suitable with it, is hexagon.Described the 1st main shaft 8 and the 2nd main shaft 9 adopt the 40Cr steel, and the 40Cr steel is strengthened the toughness of main shaft through modifier treatment.The utility model adopts PLC electrical autocontrol system, control machine startup, stop, manually just changeing, manually counter-rotating, rotating automatically, promptly stop and normally stopping supervisor, realization hommization operation, especially after the metal pulverizer was stuck, the drive motors electric current can sharply increase, current values by the PLC setting, judge whether machine is stuck, and program can be reversed automatically then, avoids burn-down of electric motor.
