when the invention is fed, the material guide wheel 8 at the left side can only rotate clockwise, the material guide wheel 8 at the right side can only rotate anticlockwise, the material guide rod 7 keeps the elasticity of upward rotation, the plastic pieces can only vertically move downwards and are clamped and crushed by the crushing mechanism, the situation that the plastic pieces are blocked at the upper part of the crushing mechanism to stop the crushing process is avoided, the supporting rotating shaft 9 at one side is driven by the engine, the supporting rotating shaft 9 at the other side is driven by the meshing transmission of the transmission gear 11, so that the supporting rotation shaft 9 at the left side rotates clockwise and the supporting rotation shaft 9 at the right side rotates counterclockwise, so that the two rows of crushing roller discs 12 rotate from two sides to the middle, the two rows of crushing roller discs 12 firstly clamp the lower end of the plastic piece and drag the plastic piece downwards along with the rotation of the two rows of crushing roller discs, thereby conveying the plastic pieces vertically downward and separating the plastic pieces into plastic pieces by the shearing force and the clamping force between the crushing roller disks 12;
when the plastic fragments fall into the stirring and crushing mechanism 6, the driving motor 26 drives the rotating rod 29 and the driving fluted disc 37 to rotate, the rotating rod 29 drives the first cutter 31 and the second cutter 32 to stir and crush the plastic fragments falling from the circular conveying groove of the limiting plate 13, the driving fluted disc 37 drives the two driving fluted discs 38 to rotate, and then the supporting fluted disc 36 is driven to rotate, so that the transmission cylinder 28 is rotated, and the side cutter 33 is driven to rotate, the side cutter 33 forms a shearing cutting structure by combining with the cutting hole 24, plastic sheets and plastic fragments with undesirable sizes which fall on the cutting hole 24 are sheared and chopped, and simultaneously, a user rotates the transmission toothed ring 17 by rotating the adjusting rotating wheel 25, thereby adjusting the size of the area for shielding the cutting holes 24 by rotating the shielding plate 19, thereby adjusting the diameter of the plastic fragments capable of passing through the cutting holes 24, thereby dividing the plastic piece mincing mechanism 6 into plastic fragments with the required size;
when the mincing mechanism 6 works, the fan 4 sucks the outside air into the supporting air guide pipe 14, so that the air guide cover and the supporting air guide pipe 14 are used for air cooling and heat dissipation of the driving motor 26, and overheating damage to the driving motor 26 is avoided.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
