Abstract

Disclosed is a biroller type shear disintegrating machine for disintegrating tenacity materials, such as waste printed circuit board, waste plastic, waste rubber, waste batterie, etc., in particular to the tabular materials with high disintegrating tenacity, hardness and stiff. The utility model comprises a frame (8), a motor reducing gear (1), a clutch (2), a driving roller (5) and a driven roller (6). The utility model is characterized in that the structure of the driven roller and the driving roller is identical, the surface of the driven roller and the driving roller is formed a groove shape distribution by the straight tooth (51) and the straight teeth of the two rollers move oppositely with mutual interlocking, the interlocker is provided with a blade (52). The utility model is that it is simple in structure, low in power expenditure, convenient in operation and maintenance, low in dust content and noise. The utility model is a new biroller type shear disintegrating machine with shearing as main force, especially for disintegrating the tabular materials of high bruising tenacity, hardness and stiff.

Description

The double-roll type shear breaker

Technical field

The utility model relates to the coarse crushing device of toughness materials such as a kind of waste and old printed circuit board, waste or used plastics, rubber and old and useless battery, and particularly a kind of double-roll type shear breaker belongs to the disintegrating machine class.

Background technology

Mining, the used disintegrating machine of ore dressing and chemical industry department, description is very many, mainly contain: based on the jaw crusher of crushing, based on the gyratory crusher of crooked and impact, based on the impact crusher of impact, to crush and to be cut into main kibbler roll, dust and noise that the said equipment not only produces are big, and be not suitable for that fragmentation is not flexible, hardness is higher, toughness waste materials preferably, as tabular materials such as waste and old circuit board just belong to not flexible, hardness is higher, toughness waste materials preferably, be not suitable for by existing coarse crushing equipment fragmentation.

Technical scheme

The purpose of this utility model just provides a kind of simple in structure, and power consumption is low, convenient operating maintenance, and dust and noise are little, based on the double-roll type shear breaker of the broken good toughness of being specifically designed to of shearing force, hardness height, unbending tabular material.

The utility model is by frame, rack-mounted motor reducer, the shaft coupling that links to each other with motor reducer, the drive roll that is connected with shaft coupling by bearing, form by gear-driven driven roll by drive roll, it is characterized in that driven roll is identical with the structure of drive roll, its surface forms flute profile by straight-tooth and distributes, the engaged move toward one another of doing of the straight-tooth of two rollers, occlusion portion has the edge of a knife.The edge of a knife of occlusion portion carries out shearing-crushing to material.The size that the spacing of change straight-tooth can be regulated broken material.

The beneficial effects of the utility model are, double-roll type shear breaker based on the broken good toughness of being specifically designed to of shearing force, hardness height, unbending tabular material is provided, and it has simple in structure, advantage such as power consumption is low, convenient operating maintenance, dust and noise are little.

Embodiment

Ask for an interview accompanying drawing, during work, rack-mounted motor reducer, the shaft coupling that links to each other with motor reducer drive drive roll by bearing and rotate, and drive roll is by the gear drive driven roll.Driven roll is identical with the structure of drive roll, its surface forms flute profile by straight-tooth and distributes, the engaged move toward one another of doing of the straight-tooth of two rollers, occlusion portion has the edge of a knife, in the time of when material drops to two rollers by feeding mouth in the middle of, contact with working roll (drive roll, driven roll), under working roll normal pressure, frictional force effect, be involved in crusher chamber by the breaker roll of two move toward one another; The edge of a knife of every pair of engaged straight-tooth forms shearing force to material respectively, and when the shearing force of the working roll of two move toward one another during greater than the broken limit of material, material is by the edge of a knife shearing-crushing of interlock part.Simultaneously material is cut into the fillet close with the straight-tooth width.Through second level fragmentation, just flat board can be broken into the fritter of 15-20mm.The size that the spacing of change straight-tooth can be regulated broken material.Bottom at working roll is provided with baffle plate, and the inboard of baffle plate is provided with device for discharging, prevents that material from stopping up in the flute profile discaling roll; The spacing of driven roll and drive roll can be regulated according to material thickness, hardness and treating capacity, will be according to identical label, to prevent two roller interferences of tooth collision during adjusting.On behalf of the roller spacing, the label on Fig. 4 bearing cup increase gradually.

Claims

1, a kind of double-roll type shear breaker, by frame (8), rack-mounted motor reducer (1), the shaft coupling (2) that links to each other with motor reducer, the drive roll (5) that is connected with shaft coupling by bearing (3), form by the driven roll (6) of gear (7) transmission by drive roll, it is characterized in that driven roll is identical with the structure of drive roll, its surface forms flute profile by straight-tooth (51) and distributes, the engaged move toward one another of doing of the straight-tooth of two rollers, and occlusion portion has the edge of a knife (52).
