In Fig. 5, illustrated rotation crushing cutter in main body 40 10 and can kinetochore breaking 60, the allocation position relation of fixed tablet breaking 70 etc.As mentioned above, in main body 40, rotate crushing cutter 10 and can configure up and down abreast with axis by kinetochore breaking 60.In embodiment, enable for the position of the knife face process of rotation crushing cutter 10 with by can kinetochore breaking 60 and the fixed tablet breaking 70 disconnected position of processing of grain of carrying out approach, and utilize rotation crushing cutter 10 again by grain is disconnected process in residual object being treated scrape off.
In existing apparatus, when object being treated being carried out to grain when disconnected, object being treated be trapped in a breaking near, may make object being treated cannot move to the disconnected position of grain, if but make to rotate crushing cutter 10 through near the disconnected processing of grain position as present embodiment, just can reliably object being treated be transported to the disconnected position of grain, thereby can eliminate because object being treated is detained, cannot carry out the such problem of the disconnected processing of grain.In addition, because difform object being treated cannot mesh such in the situation that with grain breaking, by object being treated is scraped, and use rotation crushing cutter 10 and dead knife 12 again to carry out fragmentation, just can carry out grain in the disconnected mode of easy grain and break.
Can as circular motion, swing by kinetochore breaking 60, but utilize circular motion to carry out the disconnected structure of grain by the shape of being located at shearing blade 62 that can kinetochore breaking 60 is made as, just can to object being treated, carry out grain identically with existing grain breaking and break.The object being treated dropping into from main body 14 in main body 40, is first rotated crushing cutter 10 and dead knife 12 is broken into comparatively thick, below towards main body 40 falls, by can kinetochore breaking 60 and 70 of fixed tablet breakings disconnected after, from the tap 56a of the bottom of main body 40, towards below, fall.Can kinetochore breaking 60 and the disconnected effect of grain carried out of the disconnected effect of grain carried out of fixed tablet breaking 70 and above-mentioned conventional example substantially constant.
Fig. 6 shows that the grain of present embodiment uses in off line can kinetochore breaking 60 assembly drawing.As mentioned above, be located at can kinetochore breaking 60 shearing blade 62 for object being treated grain is disconnected compared with little and formed by the pocket knife of several millimeters of degree.Therefore, it is quite difficult on manufacturing.In addition, can kinetochore breaking 60 swinging and that object being treated is carried out to grain is disconnected of present embodiment, therefore, need to form curved surface, is utilizing electric discharge processing etc. to process in so common processing method, and its manufacture is extremely difficult.
In the present embodiment, adopted by a plurality of shearing blades 62 connect assemble can kinetochore breaking 60 structure be because: it is more easy in other operation, only to manufacture in advance shearing blade 62 and above-mentioned shearing blade 62 combinations are formed to can kinetochore breaking 60 such manufacture, and can manufacture reliably.Front view and the side view of shearing blade 62 have been shown in Fig. 7.Be located at can kinetochore breaking 60 shearing blade 62 and the conventional example shown in Figure 13 in can there is in the same manner the 3rd shearing blade tip 62a and the 4th shearing blade tip 62b by moving knife 20b.The 3rd shearing blade tip 62a once cuts off for object being treated, and the 4th shearing blade tip 62b cuts off for secondary.
In once cutting off, the disconnected thing of grain is outstanding and fall towards the 3rd shearing blade tip 62a, in contrast, in secondary is cut off, the disconnected thing of grain because of the second shearing blade of fixed tablet breaking outstanding towards the rear of the 4th shearing blade tip 62b.Therefore, on shearing blade 62, need to arrange the through hole that can make the disconnected thing process of above-mentioned grain.The groove 62c side of shearing blade 62 is cross-section and that arrange is used to form the through hole that can make the disconnected thing process of grain when shearing blade 62 is connected.As mentioned above, can kinetochore breaking 60 be circular-arcly and swing, therefore, can the shearing blade 62 of kinetochore breaking 60 and the shearing blade of fixed tablet breaking 70 on arc surface, slide.The inner surface of groove 62c is formed to arc surface can be swung and can mesh with fixed tablet breaking 70 by kinetochore breaking 60 for making.
As shown in Figure 6, can kinetochore breaking 60 for making above-mentioned shearing blade 62 be fixed on adjacent to each other shearing blade installation portion 60b.In embodiment, at the outer surface of shearing blade installation portion 60b, be provided with mounting groove 64, the chimeric engaging plate 66 that is fixed with in mounting groove 64, this engaging plate 66 prevents that shearing blade 62 from falling back and carrying out engaging.On shearing blade 62, be provided with for the engaging portion 62d with these engaging plate 66 engagings, when by shearing blade 62 adjacent be arranged on engaging plate 66 after, engaging plate 66 is tightened on shearing blade installation portion 60b.Like this, can obtain and axis parallel be fixed with a plurality of shearing blades 62 can kinetochore breaking 60.
It is more complicated that shearing blade 62 and the existing shearing blade using in can kinetochore breaking are compared structure.The in the situation that of only manufacturing shearing blade 62 in another engineering, can utilize the processing such as electric discharge processing to realize, but in the present embodiment, in order more effectively to obtain shearing blade 62, use the shearing blade 62 that utilizes powder injection molding figuration manufacture to go out.In the situation that utilizing powder injection molding to be shaped to manufacture, even if quite complicated shape also can be easy to manufacture, therefore, be well suited for the manufacture of using shearing blade 62 in can kinetochore breaking 60 above-mentioned.In addition, the grain off line of the present embodiment is mainly used in resin waste break, therefore, the intensity of its shearing blade 62 is also unnecessary high as scrap metal being carried out to the disconnected situation of grain, uses the shearing blade 62 going out by powder injection molding figuration manufacture just can obtain sufficient intensity.
