Abstract

The invention relates to a high-yield rubber and plastic fine-graining machine which belongs to the crushing machinery and solves the defect of low yield of fine grains produced by the prior crusher. The high-yield rubber and plastic fine-graining machine is mainly characterized in that the shape of the section of a moving blade is composed of a plurality of concaves. The moving blade is arranged in a groove. The invention increases the cutting time of the moving blade and a fixed blade, and has high yield, high blade durability and convenient sharpening.

Description

A kind of high-yield rubber and plastic fine-graining machine

The invention belongs to crushing mechanism, be mainly used in the fragmentation of rubber and plastics.

The rubber and the plastic breaker that are using at present, no matter be vertical or horizontal, can only broken bigger particle (greater than 4mm), when need be in 4mm the particle size reduction of material, when particularly being crushed to the 1.5mm left and right sides, its particle output will reduce significantly, can only reach granularity greater than 4mm particle output 1/5th in addition lower.The granularity of for example making the required particle of rubber floor tile the top one deck need reach about 1.5mm, and making is got up to take a lot of work when giving up and production cost increases substantially.Cause above shortcoming mainly be disintegrating machine moving knife quantity very little, shear that number of times is few to be caused.All have the people of certain understanding all to know to disintegrating machine, and the core of disintegrating machine is exactly a cutter, and the disintegrating machine design is reasonable to be exactly to depend on that its Tool Design is reasonable.As Fig. 1, Fig. 2 generally use for prior art two in the version of disintegrating machine.

Summary of the invention:

In order to overcome the deficiency that existing rubber disintegrating machine and plastic breaker fine grained yield poorly, the invention provides a kind of vertical or horizontal high yield rubber and plastics fine-graining machine.This rubber and plastic fine-graining machine is the output height not only, and the tool life height, and sharpening is convenient.

The technical solution adopted for the present invention to solve the technical problems is: vertical or horizontal rubber and plastics fine-graining machine, the section of moving knife body has a plurality of character cut in bas-relief shapes evenly to distribute, and tight cutter briquetting, blade, cutter crack adjusting pad, lock washer and trip bolt are housed in its groove; Tight cutter briquetting is installed in the middle of the groove, and both sides are cutting blades, and the adjustment pad is installed behind the cutting blade; Two faces of tight cutter briquetting, fastening two or more blades simultaneously; The angle shape of tight cutter briquetting is identical with the angle shape of moving knife body groove; Existing through hole on the tight cutter briquetting has screw again; Adjustment pad behind the blade is used to adjust the rotating diameter of cutting blade; Screw on the tight cutter briquetting is used for dismounting, and its through hole is used for fastening.

The invention has the beneficial effects as follows: because the moving knife body has adopted concave structure, can adorn plural blade in one of them cutter groove, and uniform groove more than 13 on the moving knife body, (promptly a groove is adorned two blades by minimum calculating, have 13 grooves altogether), whole moving knife body has 26 cutters, and prior art can only be adorned 3 cutters, that is to say that its shearing number of times of this structure is 8.66 times (26/3=8.66) of prior art.If adorn plural blade in a groove, it shears number of times also will increase, so output also can correspondingly increase.And, because cutter of the prior art has been become blade, the used material of blade reduces, cost is low, therefore can select for use high performance material to make blade, the durability of cutter has also improved, and can keep sharp state for a long time, make output keep very high state, its total output is higher than 8.66 times.And because cutter has become blade, its size reduces greatly, and sharpening is also convenient.In sum: number of times increases substantially and tool life increases substantially owing to shearing among the present invention, so output improves greatly and production cost reduces significantly.

Below in conjunction with accompanying drawing the present invention is further specified:

Fig. 1, a kind of version of generally using for prior art.

Fig. 2, the another kind of version of generally using for prior art.

Fig. 3, A-A of the present invention cut open and attempt.

Fig. 4, B-B cutaway view of the present invention (groove part expresses clearly in A-A portion view, so part is omitted).

Fig. 5, be tight cutter briquetting fastening two cutaway views simultaneously with cutter.

Fig. 6, be the front view of fastening briquetting.

Fig. 7,, attempts the A-A of fastening briquetting for cuing open.

In the accompanying drawing: 1, feed hopper, 2, adjust pad, 3, cutting blade, 4, soket head cap screw, 5, lock washer, 6, tight cutter briquetting, 7, moving knife body, 8, go up stationary knife, 9, the stationary knife fastening bolt, 10, stationary knife, 11, stationary knife are adjusted bolt down, 12, screen cloth clam member, 13, the screen cloth fastening bolt, 14, screen cloth, 15, bearing block loam cake, 16, bearing, 17, bearing (ball) cover, 18, frame, 19, motor, 20, motor pulley, 21, belt, 22, big belt pulley, 23, bearing block, 24, tool fixing frame.

Specific embodiments

Shown in accompanying drawing: bearing block 23 is placed on the frame 18 uses bolted, two bearings 16 are installed in the two ends of moving knife body 7, then moving knife body 7 is contained in (bearing block is the Hough formula) on the bearing block 23, then bearing block loam cake 15 and bearing block 23 cooperations is used bolted again; Again bearing (ball) cover 17 is installed on the bearing block, at last big belt pulley is contained on the axle of moving knife body, connect mutually with motor pulley 20 with belt 21.Install to adjust cutter: cutting blade 3 is respectively charged in the groove, tighter cutter briquetting is packed in the groove, at last lock washer 5 is packed into and fastening with hexagon socket head cap screw 4; To descend stationary knife 10 to be installed on the tool fixing frame 24, and adjust bolt 11 with stationary knife and adjust stationary knifes 10 down, and make gap between the blade of its blade and cutting blade 3 between 0.3～0.5; Use the same method and adjust to go up stationary knife 8, make gap between the blade of its blade and cutting blade 3 also between 0.3～0.5, with stationary knife fastening bolt 9 about stationary knife fastening; At last screen cloth 14 is loaded onto, with screen cloth pressing plate 12, screen cloth fastening bolt 13 that screen cloth is fastening.The thickness specification of adjusting pad is divided into: 0.5,1,1.5,2,2.5,3,4 etc.After cutting blade 3 was through over a long time work and sharpening, its size can diminish (less than original size L), at this moment needed to add the corresponding pad of adjusting in its back and made its overall size equal the original size L of cutting blade substantially.Blade and stationary knife are ordered to specialized factory, and other spare and accessory parts belong to normal processing technology.The screw of two M16 on the tight cutter briquetting 6 is used for dismounting.

The course of work is as follows: check feed hopper 1, whether ironware or other foreign matter are arranged in the screen cloth 14, whether soket head cap screw 4, stationary knife bolt 9 are tightened.After checking normally, close feed hopper 1, open motor 19, should note the direction of rotation of motor this moment.Motor drives 7 rotations of moving knife body by small belt pulley 20, belt 21, big belt pulley 22.After treating that motor reaches at full speed, feed intake to feed hopper.Material leads to the campaign of relative shear repeatedly of cutting blade and ledger-plate and is shredded, and discharging less than the material of mesh size becomes certified products, is driven by cutting blade greater than the underproof material of mesh size and is sheared till becoming certified products repeatedly.

So-called standing crusher is exactly that moving knife body assembly is vertical placement with stationary knife body assembly; Horizontal crusher be exactly moving knife body assembly and stationary knife body assembly be horizontal positioned.Standing crusher is used seldom in the rubber and plastic industry.
