Abstract

The utility model relates to a fragmentating machine. Only a pair of mill rolls is used, different sizes of materials can be fragmentated with needed granularity through adjusting the distance of a mill roll shaft, namely spatial size between two mill roll working faces. Axial grooves and circumferential teeth are arranged on the cylindrical surfaces of two mill rolls. A regulating pilot is arranged on the shaft of one mill roll, a slide block can reciprocate through the rotation of an adjusting screw rod and the elasticity of a spring, the roll shaft can be driven to move, and the spatial size of the working faces can be controlled. Besides the fragmentation of the bones of domestic animals and poultry such as cattle bones, pig bones, chicken bones, duck bones, etc., the machine can also be used for processing other a plurality of kinds of materials such as the fragmentation of plant stalks and stem tubers, rolling juice, the fragmentation of plastic and rubber, etc.

Description

Adjustable cutter

The utility model relates to a kind of fragmentation machinery, specifically is a kind of adjustable shredding machine.

Existing bone thing size reduction machinery is made up of primary breaker and second reduction machine two parts, primary breaker has a pair of big and heavy roll, is used for bulk materials is rolled into fritter, and can not continues fragmentation, second reduction machine (China Patent No. 91232664.6) has two groups of rolls, to do further fragmentation.The major defect of this kind equipment is: 1. complex structure, manufacturing cost height; 2. roll is many, and energy consumption is big; 3. appearance and size is big, and floor space is many, and because of the inconvenience of feeding in raw material highly greatly; 4. the two roll mandrel wheelbases of a pair roller immobilize, and can not regulate, and newly roll material fragmentation degree and can't control as required; 5. in processing during pulp, first broken, attritioning high efficiency, the efficient of fiberizer is but very low, and its work does not match, and causes the broken utilization rate of equipment and installations of roller extremely low.

The purpose of this utility model provides a kind of adjustable shredding machine, has only a pair roller, promptly realizes the fragmentation of material in the gap between two rolling faces by regulating the roll mandrel distance, to reach desired particle size.

Embodiment of the present utility model is such, adjustable shredding machine comprises casing, roll, drive disk assembly, charging and discharging mouth and cleaning plate etc., the major technique feature be roll 16 the axle on adjusting device is housed, its slide block 3 is contained in the two ends of roll mandrel 5 by bearing 6, one end of slide block is near adjusting screw(rod) 4, the other end contacts with spring 7, gear 9 and 10 equal diameters, the number of teeth is identical, drive sprocket 8 and 11 equal diameters, the number of teeth is identical, and driven sprocket 1 and 2 diameters do not wait, sprocket wheel 2 diameters are big, and sprocket wheel 1 diameter is little.

The slide rail that slides for slide block is arranged on the box bilateral wall.

Adjustable shredding machine is by motor 13 driving work, and

gear

12,10,9 meshes, and drive sprocket 8 and 11 rotates synchronously with gear 9 and 10 respectively, and sprocket wheel 8 drives driven sprockets 2 and also makes roll 16 work, and sprocket wheel 11 drives sprocket wheels 1 and also makes roll 15 work.Material adds after the roll fragmentation from charging aperture 14 discharges from discharging opening 18.Because gear 9,10 is all identical with sprocket wheel 8,11 rotating speeds, and the diameter of driven sprocket 1 is less than the diameter of sprocket wheel 2, so the rotating speed of roll 15, is realized differential work faster than roll 16.When the processing piece material, clockwise turn adjusting screw(rod) 4, promote slide block 3 and move inward, move in the roll 16 simultaneously, two roll shop building gaps reduce, the material of processing is thin, when processing big material, counter-clockwise direction turn adjusting screw(rod), slide block drive roll 16 and outwards move under the spring force effect, two roll shop building gaps increase, and can process bulk materials.Change the size in gap on demand, can process the material of corresponding size and reach required fragmentation degree.

Compare with existing Machine for producing fresh bone slurry process equipment and similar machines, the utlity model has following advantage: 1. realize the increase of roll working clearance by adjusting device or dwindle, with the fragmentation that adapts to different big or small materials and the requirement of fragmentation granularity, not only just broken and attritioning two complete equipments integrate, reduce a set of equipment, will have two groups of rolls of second reduction machine simultaneously now and change one group into, all have when material consumption and worker significantly and reduce, both save floor space, reduced cost again.2. owing to two driven sprocket rotating speed differences, roll rotation one fast is slow, has realized differential work, and the fragmentation process is torn fragmentation in addition except that shearing fragmentation and extruding fragmentation, improved the fragmentation effect.3. have only one group of roll, device height reduces, and is convenient to reinforced and maintenance.4. the fragmentation of bulk materials can be carried out repeatedly fragmentation in an equipment, has both improved the utilization ratio of shredding machine, can mate with the work of following road defibrination operation again.5. because the roll working clearance can be in harmonious proportion the fragmentation mode and increase, and shredding machine also can be processed other various materials except that the bone of processing animals such as ox, pig, chicken and duck etc., as vegetable stem tangerine, stem tuber, plastics, rubber etc., its purposes is more extensive.
