Referring to fig. 3, the extruding assembly 3 includes a rotating shaft 31 and a plurality of elastic members 32, the rotating shaft 31 is rotatably connected to one end of the extending rod 42 far away from the fixing rod 41, and the rotating shaft 31 is perpendicular to the extending rod 42, that is, the rotating shaft 31 is parallel to the central axis of the ring die 2, and the rotating shaft 31 can rotate with the central axis as the axis. The elastic members 32 are uniformly distributed around the circumference of the rotating shaft 31, that is, a plurality of elastic members 32 are radially arranged on the outer wall of the rotating shaft 31 with the central axis of the rotating shaft 31 as the center, and the elastic member 32 on the side of the rotating shaft 31 opposite to the fixing rod 41 abuts against the inner wall of the ring mold 2. Elastic component 32 has elasticity, and when the compressive stress that elastic component 32 receives was great, elastic component 32 can be towards the axis direction shrink of pivot 31 to absorb the ability that the compressive stress that elastic component 32 receives produced, with the condition that reduces elastic component 32 and receive the excessive and damage of compressive stress, when elastic component 32 rotated to and with ring mould 2 break away from the contact along with pivot 31, elastic component 32 resilience resets, with the processing effect of assurance elastic component 32 and ring mould 2 to the material.

Referring to fig. 3, specifically, the elastic element 32 includes pushing springs 321 and an extrusion plate 322, the pushing springs 321 are radially disposed on an outer wall of the rotating shaft 31 with a central axis of the rotating shaft 31 as a center, and the extrusion plate 322 is fixed at an end of the pushing spring 321 away from the rotating shaft 31. The width of the extrusion plates 322 is the same as the width of the ring die 2, and the extrusion plates 322 have a radian matched with the ring die 2, so that the extrusion plates 322 can be tightly attached to the inner wall of the ring die 2, and the adjacent extrusion plates 322 are attached to each other, that is, a plurality of extrusion plates 322 form a compression roller, and the situation that materials flow from gaps among the extrusion plates 322 to the pushing springs 321 can be reduced. One side that extrusion plate 322 pushes away spring 321 dorsad is equipped with a plurality of burr 7 along width direction, burr 7 has both increased the roughness of extrusion plate 322, help increasing the frictional force that the material received, this has promoted extrusion plate 322 and ring mould 2 and to the extrusion pelletization effect of material, burr 7 supports pastes on the inner wall of ring mould 2 simultaneously, compare in that extrusion plate 322 directly contacts with the inner wall of ring mould 2, the area of contact of the reducible elastic component 32 of burr 7 and ring mould 2, and then reduce the frictional force between elastic component 32 and the ring mould 2, thereby form the protection.

The pushing spring 321 is sleeved on the limiting rod 5, the limiting rod 5 limits the pushing spring 321, so that the pushing spring 321 can only shrink or rebound between the extrusion plate 322 and the rotating shaft 31, and the distance between the limiting rod 5 and the extrusion plate 322 is larger than the shrinking distance of the pushing spring 321, which can reduce the possibility that the pushing spring 321 cannot shrink and unload force due to the fact that the extrusion plate 322 abuts against the limiting rod 5. The limiting groove 51 is formed in the limiting rod 5 along the length direction, the limiting groove 51 penetrates through the end face of one end, away from the rotating shaft 31, of the limiting rod 5, the guide rod 6 is fixed on one side, away from the convex line 7, of the extrusion plate 322, one end, away from the extrusion plate 322, of the guide rod 6 is arranged in the limiting groove 51 in a sliding mode, the distance between the guide rod 6 and the groove bottom of the limiting groove 51 is larger than the distance between the pushing springs 321 in a shrinking mode, the guide rod 6 and the limiting groove 51 further limit the pushing springs 321 and the extrusion plate 322, and therefore the possibility that the pushing springs 321 or the extrusion plate 322 deflect due to overlarge friction force between the extrusion plate 322 and the ring die 2 is reduced.

The end surfaces of the rotating shaft 31 are fixed with the baffle discs 8, the radius of the baffle discs 8 is the same as the length of the pushing spring 321, so that the side walls of the baffle discs 8 are attached to the side walls of the extrusion plates 322, namely the extrusion plates 322 are clamped in a pair of baffle discs 8, on one hand, the baffle discs 8 can limit the extrusion plates 322, and the situation that the extrusion plates 322 deflect due to overlarge friction force between the extrusion plates 322 and the ring die 2 is reduced; on the other hand, the blocking disc 8 can block the material, so as to reduce the situation that the material moves to the pushing spring 321 or enters the limiting groove 51 to cause the failure of the elastic element 32.

The implementation principle of the high-wear-resistance ring die granulator of the embodiment of the application is as follows: the materials are preprocessed and enter the ring die 2 in a powder form, the ring die 2 rotates to enable the materials to move in the ring die 2, the friction force between the elastic piece 32 and the ring die 2 drives the rotating shaft 31 to rotate, when the materials move to the contact position of the ring die 2 and the elastic piece 32, the elastic piece 32 rolls the materials between the extrusion plate 322 and the ring die 2, and the materials are extruded into particles through the discharge port 21 on the ring die 2 after being extruded. When the material between the extrusion plate 322 and the ring die 2 is more, the pushing spring 321 contracts and continuously extrudes the material, and when the extrusion plate 322 rotates to leave the ring die 2, the pushing spring 321 rebounds and resets the extrusion plate 322 so as to continuously process the material.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
