As shown in FIG. 2, a pushing plate 20 is arranged on the end face of one side, close to the opening, of the supporting plate 17, the pushing plate 20 slides along the oblique direction of the supporting plate 17, a linkage plate is fixed on one side, far away from the opening, of the pushing plate 20, the linkage plate penetrates through the supporting plate 17 and slides along the oblique direction of the supporting plate 17, and the linkage plate is in power connection with a power output end of a second electric cylinder 21 in the electric cylinder power portion.
In the initial state, in the view of fig. 2, the left plane of the shielding block 23 abuts against the supporting box 29, the right plane of the shielding block 23 is perpendicular to the bottom surface of the crushing box 10, the pushing plate 20 is located at the rightmost side of the movable stroke, the pressure plate 16 abuts against the supporting box 29, the balance plate 33 is in the horizontal state, the blocking door is in the closed state, the arc-shaped adjusting piece 42 is in the middle position of the movable stroke, and the spring 43 is compressed.
During the use, pack into crushing box 10 with discarded plastic sheet from the opening part of crushing box 10 in, plastic sheet piles up at the pushing plate 20 upper surface this moment, motor 12 moves simultaneously, will rotate the moment of torsion through the output of motor 12 and transmit to crushing wheel 22 on, thereby make crushing wheel 22 rotate, crushing wheel 22 rotates the in-process and will pile up the plastic sheet pulling breakage at the pushing plate 20 upper surface through the effect of cutting edge and fixed sword, the piece after the breakage drops to sieve 24 upper surface under the action of gravity, motor 12 drives camshaft 54 through the pulley group and rotates simultaneously, thereby make cam 51 rotate, because cam 51's structural characteristic, striking pole 50 is along spacing box 53 linear motion from top to bottom, thereby make sieve 24 strike reciprocal linear motion from top to bottom with the butt of pole 50, thereby make sieve 24 produce the vibration, thereby make the material disperse under the vibration effect, and begin to move to the direction of first receiver 30, the material that is less than the screening hole diameter passes sieve 24 under the vibration effect and falls into third receiver 32 and second receiver 31 respectively and stores simultaneously, two sets of the final receiver 30 that get into first hole.
When the distance between the fixed blade and the cutting blade is too small, the volume of the crushed material is too small, that is, the crushed material enters too much the third storage box 32, at this time, the weight in the third storage box 32 is greater than the weight in the first storage box 30 and the sum of the friction force between the balance rotating shaft 34 and the friction layer in the striking rod 50, at this time, the third storage box 32 moves downward, the gravity is transmitted to the end of the balance plate 33 through the gravity transmission rod, so that the balance rotating shaft 34 rotates counterclockwise (refer to the view angle of fig. 2) to drive the balance gear 37 to rotate counterclockwise, so that the second rack 36 moves to the right side (refer to the view angle of fig. 2), so that the pulling rope 38 is pulled to the right side (refer to the view angle of fig. 2), so that the pulling rope 38 pulls the second electric cylinder 40 to be recovered into the fixed box 44, so that the distance between the arc-shaped adjusting blade 42 and the crushing wheel 22 becomes large, because the flexible shielding blade 41 is made of a flexible material, at this time, both ends of the flexible shielding blade 41 are only wrinkled and bent, thereby it is cutting edge and fixed sword distance grow to make the material size grow after the breakage, in order to reduce the volume that the material got into third receiver 32 through the screening hole, thereby make the volume that gets into in second receiver 31 or the first receiver 30 increase, finally make balance plate 33 get back to the horizontality again, the material weight in the third receiver 32 this moment is greater than the material weight in the third receiver 32, the gravity numerical value of the material that goes out is the frictional force numerical value between balanced pivot 34 and the interior friction layer of support base 35 roughly, when balance plate 33 gets back to the horizontality again, through the reverse motion of above-mentioned process, make the distance between fixed sword and the cutting edge diminish, if the interval between fixed sword and the cutting edge is too big at the beginning, lead to the material weight in the first receiver 30 after the long-time breakage to be greater than the weight in the third receiver 32 and balanced pivot 34 and support base 35 When the frictional force of interior friction layer was in sum, balanced pivot 34 clockwise (refer to fig. 2 visual angle) fixed sword was opposite with the motion mode of cutting sword this moment, can make the material volume in third receiver 32 and the first receiver 30 roughly equivalent through the process, and the condition of the too big undersize of broken material has been avoided appearing, improves the material volume that gets into in the second receiver 31.
When the plastic sheets are excessively accumulated at the opening of the crushing box 10, so that part of the sheets extend to the outside from the opening of the crushing box 10, and the feeding of the sheets and the crushing efficiency of the crushing wheel 22 are affected, the first electric cylinder 15 acts to push the pressure plate 16 to move horizontally, the sheets are extruded into the crushing box 10 under the pressing action of the inclined surface of the pressure plate 16, the first rack 25 moves out of the support box 29 along with the horizontal movement of the pressure plate 16, the meshing gear 28 rotates at the moment, the winding wheel 27 is driven to rotate through the connecting shaft, so that the connecting rope 26 is loosened from the winding wheel 27, the blocking piece 23 rotates anticlockwise under the action of the torsion spring at the rotating shaft (refer to the view angle of fig. 2), the curved surface part of the blocking piece 23 faces the feeding direction of the pushing plate 20, so that the sheets are extruded in the crushing box 10 under the pressure plate 16, and the sheets rapidly enter the crushing positions of the cutting edge and the fixed edge under the guiding action of the curved surface of the blocking piece 23, and the crushing efficiency is improved;
when the sheet material is crushed, the second electric cylinder 21 drives the pushing plate 20 to reciprocate along the inclination direction of the supporting plate 17, so that one end of the sheet material is pressed to the crushing wheel 22 when the pushing plate 20 is close to the crushing wheel 22, the contact pressure between the sheet material and the cutting edge is improved, when the pushing plate 20 is far away from the crushing wheel 22, a part of the sheet material accumulated on the upper surface of the pushing plate 20 can fall between the end part of the pushing plate 20 and the crushing wheel 22, and the sheet material can be pressed to the crushing wheel 22 by the pushing plate 20 for crushing next time.
The materials accumulated in the third storage case 32, the second storage case 31, and the first storage case 30 can be taken out by opening the shutter.
