Abstract

The utility model provides a novel rubber-plastic disintegrating machine, the roller of which adopts an assembly type, and the roll surface has fine and multiple grooves. The utility model is mainly used for cutting. The utility model has the advantages of high yield, little power consumption and low maintenance cost without replacing the entire roller but to replace the jacket of the roller.

Description

Novel rubber and plastic pulverizer

The utility model belongs to a kind of disintegrating apparatus in the rubber plastic machinery.

The rubber crusher of making and generally using is to turn round relatively with different speed with two rollers at present, and the sizing material of processing is drawn between two rollers, makes the broken or pulverizing of sizing material under the effect of large speed ratio.Its major defect of the rubber crusher of this pattern is the energy consumption height, yields poorly.This pulverizer energy consumption height, the main cause that yields poorly be, general two rollers all are smooth roll, and it is very unscientific " rubbing with the hands toughness, the high rubber of flexibility broken " with smooth roll, so output is extremely low.With the pulverizer that has groove on the roller, but because groove dimensions is too big, be used in small, broken bitsly, output is lower, and roller is monoblock type, and general being difficult to repaired behind the blunt, so incompatible requirement of pulverizing (in small, broken bits).The fine crusher of with groove is similar on plastic breaker and the roller, but because the space between its blade and the blade is bigger, and more be not suitable in small, broken bits.

Goal of the invention of the present utility model is the deficiency of above-mentioned substantially size reduction machinery, provides a kind of rational in infrastructure, efficient height, the novel rubber and plastic pulverizer that energy consumption is low.

Provided by the utility model a kind of novel rubber and plastic pulverizer in order to achieve the above object, include motor 1, shaft coupling 2, reduction box 3, bearing 4, pinion 8, bull wheel wheel 9 and pressure roller, bearing 4 is contained on the diameter of axle of pressure roller, again pinion 8, gear wheel 9 is contained on the diameter of axle of corresponding pressure roller, then bearing 4 is contained on the Hough bearing block; At last shaft coupling 2, gearbox 3, motor 1 connects and is fastening.It is characterized by: pressure roller is an assembly type, and by pressure roller overcoat 5, pressure roller shaft 6 and key 7 are formed.The groove width L of pressure roller overcoat 5 is less than 8 millimeters; The degree of depth h of groove is less than 5 millimeters.Below in conjunction with accompanying drawing the utility model is given further instruction.

Fig. 1 is a structural representation of the present utility model;

Schematic diagram when Fig. 2 is reticulate pattern for pressure roller external diameter groove;

Schematic diagram when Fig. 3 is twill (helix) for pressure roller external diameter groove;

Schematic diagram when Fig. 4 is straight burr for pressure roller external diameter groove;

Fig. 5 is the sectional drawing of the utility model pressure roller;

In the accompanying drawing: 1 is that motor, 2 is that shaft coupling, 3 is that gearbox, 4 is that bearing, 5 is that pressure roller overcoat, 6 is that pressure roller shaft, 7 is that key, 8 is that pinion, 9 is a gear wheel; L is the width of pressure roller groove, and h is the degree of depth of pressure roller groove.

Shown in the by specification accompanying drawing: earlier bearing 4 is contained on the diameter of axle of pressure roller, again pinion 8, gear wheel 9 is contained on the diameter of axle of corresponding pressure roller; Then bearing 4 is contained in (not shown) on the Hough bearing block.Connect shaft coupling 2, gearbox 3, motor 1 also fastening at last.

The course of work is such: motor 1 drives the initiative compression roller rotation by shaft coupling 2 gearboxes 3, and the pinion 8 on the initiative compression roller drives gear wheel 9 rotations.Thereby the transmission of two rollers by big pinion is with different speed ratio counter-rotatings.Treat that motor reaches the middle pellet that drops into coarse crushing of past two pressure rollers in back at full speed.Coarse fodder is through stranding, shearing, the roll extrusion of two pressure rollers, and falls into the sieve of vibration, becomes the qualified powder of certain order number through the think of screen cloth in the vibratory sieve; Underproof material is being sent back to from new rolling cut.

Because pressure roller overcoat of the present utility model is thin one by one cutter tooth, so broken rubber output is very high, motor power (output) is about half of Vintage Product.And cutter tooth only needs to change overcoat after pure, and does not need to change whole roller.

Realize the utility model as long as pressure roller is become pressure roller shaft and pressure roller overcoat two parts.Pressure roller is applied mechanically alloy tool steel outward and is forged the back Vehicle Processing, makes tooth then and quenches quenching hardness HRC55-60.
