Referring to fig. 2, 3 and 12, two limiting strips 30 are formed on one side of the handle 19 of each cutting blade 16, the length direction of each limiting strip 30 is consistent with the radial direction of the rotating shaft 13, and a strip-shaped limiting groove 31 matched with the corresponding limiting strip 30 is formed on each strip-shaped rotating arm and the corresponding strip-shaped fixing arm 20.
The cooperation of the limiting strip 30 and the strip-shaped limiting groove 31 is used for limiting the up-and-down movement of the handle part 19 of the cutting blade 16 when the handle part 19 is transversely inserted into the slot 21, so that the handle part 19 of the cutting blade 16 can be smoothly inserted into the slot 21, and each limiting pin 23 can pass through the corresponding insertion hole 29 when elastically resetting.
Referring to fig. 2, the fixed bolt 32 that is circular array that is equipped with a plurality of outer fringe department of splint 8, every bolt 32's axial all is unanimous with splint 8's axial, No. two splint 9 go up the outer fringe department shaping have a plurality of to be circular array's arc to lead to groove 33, a plurality of arc leads to groove 33 and a plurality of bolt 32 one-to-one, the through-hole 34 that supplies the cap end level of the bolt 32 that corresponds to pass is all seted up to the one end that every arc leads to groove 33, the pole portion of every bolt 32 all passes the arc that corresponds and leads to the groove 33 and all can slide in the arc that corresponds leads to the groove 33 after splint 9 rotates.
When the rubber air bag 4 is clamped and fixed, because each clamping convex ring 10 needs to be ensured to be clamped in the corresponding clamping embedding groove 11, therefore, the whole installation sequence should firstly fix the first clamping plate 8 and one end of the feeding barrel 1, then align a plurality of clamping caulking grooves 11 arranged on one side of the rubber air bag 4 with a plurality of clamping convex rings 10 on the first clamping plate 8, the second clamping plate 9 is then held by hand so that the through hole 34 of the second clamping plate 9 is aligned with the cap end of the bolt 32, after pressing the second clamping plate 9 toward the first clamping plate 8 so that the cap end of each bolt 32 penetrates out of the second clamping plate 9, the second clamping plate 9 is rotated, the cap end of each bolt 32 is staggered with the corresponding through hole 34 by the arc-shaped through groove 33, meanwhile, after the rubber air bag 4 is slightly inflated, the second splint 9 is immediately extruded by the rubber air bag 4 to be abutted against the cap end of each bolt 32, so that the second splint 9 is fixed;
the joint caulking groove 11 of 4 one sides of rubber gasbag this moment has with the joint bulge loop 10 looks block on splint 8, so after No. two splint 9 rotation fixings, need ensure that the joint bulge loop 10 on No. two splint 9 after the rotation can aim at the joint caulking groove 11 of block in 4 opposite sides of rubber gasbag can, because the joint caulking groove 11 of 4 every sides of rubber gasbag is circular array, angle between each other is unanimous, so when processing the arc logical groove 33 on No. two splint 9, it can for the integral multiple of the angle between two adjacent joint caulking grooves 11 to ensure that the arc leads to groove 33 length can satisfy the angle of No. two splint 9 backs of revolving.
Referring to fig. 1, a collecting box 3 is fixedly arranged right below the double-layer clamping plate.
The collecting box 3 is used for collecting the cut and granulated rubber in a centralized way.
The working principle is as follows:
the feeding barrel 1 is always in a working state, rubber extruded from the discharge port is extruded into strips by a plurality of extrusion holes 5 formed in a first clamping plate 8 and is led to a corresponding rubber tube 7, when the particle size of rubber particles needs to be changed, the rubber air bag 4 is inflated, two sides of the rubber air bag 4 cannot expand due to the limitation of the first clamping plate 8 and a second clamping plate 9, then gas in the rubber air bag 4 can intensively extrude the rubber tube 7 between every two symmetrical reducing holes 6, then the rubber tube 7 can be contracted due to compression elasticity, the whole tube diameter can be reduced (namely the extrusion force applied to the rubber tube 7 is shown by the arrow in figure 6), so that the rubber strips in the rubber tube 7 can be extruded and reduced in diameter, the rubber strips after being reduced in diameter can pass through the plurality of extrusion holes 5 formed in the second clamping plate 9 and are strips, at the moment, the rotating rubber strips 16 can be cut, make the rubber strip be graininess, the graininess rubber strip that is descends along cutting blade 16's cutting part 18 slant, finally fall to accomplish in the collecting box 3 and collect, wherein, the both sides of rubber gasbag 4 are restricted by splint 8 and No. two splint 9, but aerify the back gas still can follow the inner wall of rubber gasbag 4 of extrusion all around of rubber gasbag 4, so when making rubber gasbag 4, be the cake form with rubber gasbag 4 system, and the rubber of rubber gasbag 4 both sides is thinner, the thick elasticity low difficult inflation of rubber all around, be similar to the rubber hot-water bottle, with this guarantee that rubber gasbag 4 aerifys the back, the atmospheric pressure in it can concentrate extrusion rubber tube 7, thereby realize the reducing function of rubber tube 7.
