Impulsive force, be provided with buffer spring bottom charging box 13.
The work process of formation system 1 is: be first positioned over by stalk in first-level transport mechanism 140, transmits through it
To roller mechanism 144, after the compacting of roller mechanism 144, enter two-stage conveying mechanism 143, and by flat material auxiliary band
By the lower section of shear 11 after the adjustment of 141, now, the shearing auxiliary body 111 at cutting mechanism 112 two ends fortune downwards
Dynamic, after its binder parts 1111 press fixing straw, cutting knife 1122 moves downward cut-out straw, will straw cutting be default
Length, then cutting knife 1122 rollback travels upward and out straw, shears auxiliary body 111 and moves then up.Two-stage conveying
Straw after mechanism 143 will cut off inputs from the charging aperture 1222 of shaped device 12, treats that it detects preset weight or volume
Rear extrusion piston 121 moves downward straw extrusion in bulk, and the static several seconds makes stalk forming fasten, and prevents or reduces elastic returning
Become.Now, charging box 13 according to predetermined program just past and rest on the lower end of molding cylinder body 122 bottom opening, now,
Pinion and rack pull-out feeding plate 1221, opens molding cylinder body 122 bottom opening, and the straw block after molding i.e. falls into charging box
In 13, and it is delivered to the conveyer belt of three grades of conveying mechanisms 14260The porch of Co-γ irradiation system.
In the present embodiment60Co-γ irradiation system 2 includes radiation chamber 21, irradiation source plate 22, radiation chamber 21 generally cement
Pouring, prevent emittance from leaking, wherein radiation chamber is the full of twists and turns design of labyrinth type, prevents at charging box 13 into and out
Time, from the internal emittance that leaks of radiation chamber 21, polylith irradiation source plate 22 is arranged on the inside of radiation chamber 21, for abundant irradiation
The straw of charging box 13, in the present embodiment, the quantity of irradiation source plate 22 is 4 pieces, arranges in the most parallel, the most coplanar mode
In radiation chamber 21, thus form first irradiated site the 231, second irradiated site the 232, the 3rd irradiated site 233, the second irradiated site 232
Being positioned in the middle of two groups of irradiation source plates 22, charging box 13 is full of twists and turns through first irradiated site the 231, second irradiated site in serpentine
232, the 3rd irradiated site 233, when the first irradiated site 231, owing to being positioned at the edge part of irradiation source plate 22, irradiation intensity is relatively
Little, straw internal structure starts tentatively to destroy, and then enters the second irradiated site 232, owing to being positioned at two row's irradiation source plate 22 central authorities,
Irradiation intensity is big, and straw internal structure starts acutely to destroy, and when through three irradiated sites 233, the structure of destruction is maintained,
Inhibit bounce-back, by the irradiation pattern of " weak-strong-weak ", significantly improve destructiveness and the degree of stability of straw, and adopt
Use serpentine route, each charging box 13 can reciprocal more than 10 times through irradiation source plate 22 so that pretreatment is more filled
Point.
