The inner wall of the mounting hole is installed with a pelletizer body 9, and the pelletizer body 9 is fixed on the top frame 3 to maintain working stability. The through hole ensures the connectivity between the top frame 3 and the bottom frame 1 to avoid collision and jamming between equipment, and the process cannot operate normally. The two sides of the inner wall of the top frame 3 are rotatably connected with the rotating shaft 4 through bearings, and a distribution box 5 is arranged between the ends of the two rotating shafts 4 that are close to each other. The top of the distribution box 5 is an open setting, and the top opening of the distribution box 5 is aligned with the bottom discharge part of the pelletizer body 9. The pelletizer body 9 is aligned with the box opening connected to the distribution box 5 at its discharge part below, and the pelletized material falls into the inside of the distribution box 5.

The material particles are filtered through the sieve plates 204 to achieve rapid classification of the material particles.

[0028] Example 2

[0029] like Figure 1-5 As shown, a stirring rod 6 is arranged inside the distribution box 5, and the two ends of the stirring rod 6 are respectively movably penetrated to the two sides of the outer wall of the distribution box 5, and are respectively fixedly connected to the ends of the two rotating shafts 4 close to each other. The shaking of the distribution box 5 drives the incoming material particles to shake, and the stirring rod 6 stirs and breaks up the materials. The bottom of the distribution box 5 is connected to a discharge port 7 and is connected. The discharge port 7 is movably arranged between the inner walls of the through hole and is aligned with the cover port of the cylinder cover 202. After the material particles fall from the discharge port 7 on the distribution box 5, they enter the cylinder cover 202. An elastic mechanism 8 is arranged on the distribution box 5, and includes a U frame 801. The two ear ends of the U frame 801 are fixedly connected to the back of the outer wall of the top frame 3. A sliding hole is opened on the inner wall of the U frame 801, and a sliding arm 802 is slidably connected. The rear end of the sliding arm 802 A push piece 803 is fixedly connected, and a spring 804 is fixedly connected between the push piece 803 and the outer wall of the U frame 801, and the spring 804 is movably mounted on the rear end outer wall of the sliding arm 802, and the front end of the sliding arm 802 is hinged to the inner wall of one end of the H plate 805 through a pin, and the inner wall of the other end of the H plate 805 is hinged to one end of the rocker arm 806 through a pin, and the other end of the rocker arm 806 is fixedly connected to the top of the back side of the outer wall of the distribution box 5. The sliding arm 802 reciprocates and causes the hinged H plate 805 to produce a curved motion and drives the rocker arm 806 to move in a curved motion, and the front side of the outer wall of the elliptical plate 209 fits against the side of the push piece 803 away from the spring 804, and the elliptical plate 209 rotates eccentrically, thereby repeatedly squeezing and pushing the push piece 803, and a reaction force is formed by the elastic force of the spring 804 to realize the reciprocating motion of the push piece 803.

[0030] In this embodiment, the elliptical plate 209 is driven to rotate eccentrically during the rotation of the rotating rod 207, so that the push plate 803 drives the sliding arm 802 to slide on the U frame 801, and the reaction force is formed by the elastic force of the spring 804. The sliding arm 802 is driven to reciprocate through the rotation trajectory of the elliptical plate 209, and the rocking arm 806 is driven to move in a curve through the hinged H plate 805, so that the distribution box 5 is shaken and rotated with the rotating shaft 4 as the axis, so that the material particles can freely collide with the stirring rod 6 to be broken up, thereby avoiding accumulation and agglomeration.

[0031] When the pelletizer capable of screening and classification is used, the pelletizer body 9 refers to the technical solution of publication number CN211709768U, and the pelletizer blades are rotated alternately to pelletize the material, which belongs to one of the principles of the prior art equipment. This case will not be described in detail. The pelletizer body 9 is fixed on the top frame 3 to maintain working stability, and the discharge part below it is aligned with the box opening of the material distribution box 5, and the motor 206 is started to drive the rotating shaft 4 to rotate by its output shaft, and the outer gear ring 203 is driven to rotate by the spur gear 208. , so that the outer tooth ring 203 is limited to rotate between the classification cylinder 201 and the cylinder cover 202. When the material particles fall from the discharge port 7 on the material distribution box 5, they enter between the screen plates 204 in the cylinder cover 202. At this time, the screen plate 204 rotates with the outer tooth ring 203, thereby ensuring the activity of the material particles and avoiding the problem of concentrated accumulation in one place, which causes the screening to be immobile and the sieve holes to be blocked. The material particles are filtered by the screen plate 204. As the number of material particles increases, the material particles above the screen plate 204 will spread to the discharge port 205 and be discharged outward. The material particles in the classification cylinder 201 will accumulate one after another and form two categories with the material particles before screening, or the two categories are different in size, or the difference between the finished product and the residue and debris needs to be judged according to the actual processing situation. There are also corresponding cylinder holes on the classification cylinder 201 for recycling materials. Before screening, the rotation of the rotating rod 207 drives the elliptical plate 209 to rotate eccentrically, thereby repeatedly pushing the push piece 803, so that it drives the sliding arm 802 to slide on the U frame 801, and forms a reaction force through the elastic force of the spring 804. , the rotating trajectory of the elliptical plate 209 drives the sliding arm 802 to reciprocate, and then the hinged H-plate 805 produces a curved motion and drives the rocker arm 806 to move in a curved motion, and finally the distribution box 5 is shaken and rotated with the rotating shaft 4 as the axis. During the shaking, the inside of the distribution box 5 drives the incoming material particles to shake and freely collide with the stirring rod 6, forming a shaking and stirring effect, so that the pelletized materials are adhered to each other, the accumulated and agglomerated parts are broken up, and the particles are made clear, and the residual powder after pelletizing can also be broken up, which is convenient for subsequent screening processing.
