[0042] 44 two of external blade 42 and internal stent all have central opening 45.These openings 45 are aimed at when each cutting part 40 of assembling.At each cutting part 40 assembled and snap together after, utilize opening 45 that a plurality of cutting parts are installed or are aligned on the rotatable shaft 20.Figure 11 and 12 show in disintegrating apparatus, be used to be assembled into a plurality of cutting parts 40 that discharging element 54 on the rotating shaft and spacer 56 are aimed at.This cutting part 40 is disposed adjacent one another.Discharging element 54 and spacer 56 are arranged between each cutting part 40, and this cutting part 40 is positioned at axle and goes up or locate along axle.Because the cutting part on the cutting part when paper or other matrix are pulverized on first and second is interlaced, along with paper is admitted to cutting part 40, discharging element 54 will be used to remove pulverized paper, thereby prevent the obstruction of cutting zone and prevent that disintegrating mechanism 16 from stopping up.Provide spacer 56 to form the space, thereby the cutting part 40 on first and second 20 can be interlocked.
[0043] existence of this discharging element 54 and spacer 56 and configuration are not a kind of restrictions.Shown separation spacing device can be omitted and spacer can become one with at least one cutting part 40.For example, thus can form outstanding center bush part on blade 42 provides spacer.Perhaps, the central opening 45 of blade can be oversize, and the monoblock type center bush part 62 of internal stent 44 can extend axially (or outstanding) by central opening 45 and pass blade 42, thereby spacer is provided, as shown in Figure 16.Therefore, this spacer can have any structure or configuration.Similarly, the discharging element also can have any structure that is suitable for installing or configuration.
[0044] showing on the part of blade 42 externally equally in the drawings is jagged edge 58.In operation, this jagged edge 58 is designed to by preventing that matrix slippage in cutting process from coming the pulverizing of support substrate (for example paper).
[0045] design of external blade 42 and internal stent 44 provides use and the characteristic that is suitable for for a long time.Especially, around whole circumference supports outer blade 42, this prevents that blade 42 and tooth holder part 52 be out of shape under the effect of load, and this load is with use is relevant for a long time.
[0046] preferably, but not necessarily, external blade 42 is parallel to each other, and has parallel outer surface and inner surface.Under the situation of the beneficial effect by using the saving cost that internal stent 44 brings, this allows cutting part to cut as most traditional cutting part.
[0047] though illustrated principle of the present utility model in the above in the specific embodiment of having listed, but those skilled in the art should be understood that: in putting into practice process of the present utility model, the structure that is adopted, configuration, ratio, parts, material and assembly can be made different variations.
[0048] thus we see, fully and reached the purpose of this utility model effectively.But, will be appreciated that, in order to set forth the purpose of function of the present utility model and structural principle, illustrate and described the preferred specific embodiment in front, and can under the situation of not leaving these principles, make change.Therefore, the utility model comprises that the institute in the spirit and scope that are included in following claim changes.
