[0041] In view of the above problems, an embodiment of a swing hammer and a grinder is proposed.

[0042] Embodiment 1

Due to the small striking area, a greater impact is caused to the solid substance, improving the crushing effect; the first cutting part of the movable end 2 and the structure outside the swing hammer 1 can cooperate to form a cutting effect to cut the long fiber substance and make the long fiber shorter.

[0044] Preferably, as Figure 1 shown, the rotating part is formed with a rotating top surface, a rotating bottom surface, and a circumferential side surface connecting the rotating top surface and the rotating bottom surface; the hammer body 4 is formed with an upper top surface, a lower bottom surface, and a first side surface and a second side surface connecting the upper top surface and the lower bottom surface. The first side surface and the second side surface are formed on opposite sides of the swinging direction of the hammer body 4. The first side surface and the second side surface are respectively connected to the circumferential side surface; the first side surface is formed with a stepped structure, and the convex rib 6 of the stepped structure extends from the rotating top surface of the rotating part to the upper top surface; the striking part is formed with a stepped structure. When the swing hammer 1 swings, it can strike the object to be processed at different heights.

[0047] When the swinging hammer 1 swings, the upper mating surface 9 and the arc-shaped cutting surface 7 cut the long fibers in different directions to make the long fibers into shorter fibers, which is beneficial to discharge and also avoids the entanglement of long fibers.

[0048] Embodiment 3

[0049] Further, on the basis of Embodiment 2, improvements are made, as Figures 3-4 shown, a cutting knife 10 is formed on the side of the lower convex platform 8 of the first cutting part facing away from the connecting end 3; the thickness direction of the cutting knife 10 is the up and down direction.

The first convex edge 6 and the second convex edge 6 extend from the edge of the first cutting part to the middle of the first cutting part. The cutting knife 10 is thick in the middle and thin at the edges, and the cutting knife 10 itself has a certain hitting ability. On the one hand, it avoids damage to the cutting knife 10 when the cutting knife 10 collides with harder substances, and at the same time, it can also break and crush harder substances.

[0053] Embodiment 5

[0054] On the basis of Embodiment 3, further improvements are made. For example, Figure 5 as shown,

[0055] On the upper side of the arc-shaped cutting surface 7, the first cutting part forms an upper convex platform 14 protruding away from the connecting end 3. The upper convex platform 14 is located above the lower convex platform 8.

The cooperation between the flaring structure and the convex structure on the inner wall surface of the grinding ring can cut long fibers.

[0056] Embodiment 6

[0057] On the basis of Embodiment 5, further improvements are made. For example, Figure 6 as shown, a circular arc-shaped groove 18 is formed on the lower bottom surface of the hammer body 4, and the groove 18 penetrates through the first side surface and the second side surface; the center of the circular arc-shaped groove 18 coincides with the axis line of the rotating part. When the swinging hammer 1 swings, the groove 18 cooperates with the first convex 19 on the grinding disc to cut long fibers.

[0058] Preferably, as Figure 3 shown, the first cutting part forms a plurality of cutting structures in different height directions; when the swinging hammer 1 swings, the plurality of cutting structures can cut the object to be processed at different heights.

When the swinging hammer 1 moves along with the grinding disc and the first cutting part passes through the second cutting part, the first cutting part and the second cutting part cooperate to form a cutting effect;

[0060] Corresponding to the improvements of the above swinging hammer embodiments, the grinding disc and the grinding ring can be adaptively improved as follows: as Figure 9 shown, the second cutting part forms a vertical knife, and when the grinding hammer swings, the first cutting part and the vertical knife cooperate to form a cutting structure and cut the object to be processed.

[0061] Preferably, as Figure 8 shown in the embodiment, limiting blocks are arranged at both ends of the swinging path of the swinging hammer 1 on the grinding disc. When the swinging hammer 1 swings, the stepped structure can squeeze and crush the object to be processed between the limiting block and the stepped structure.

[0062] Preferably, as Figure 7As shown, a first protrusion 19 is formed on the surface of the grinding disc. When the swinging hammer 1 swings and passes by the first protrusion 19, the first protrusion 19 is inserted into the groove 18, and relative movement occurs between the first protrusion 19 and the groove 18 in the groove 18 to form a cutting effect. Correspondingly, a plurality of material discharge holes are formed on the grinding disc along the swinging path of the swinging hammer 1, and when the swinging hammer 1 swings, the material can be extruded from the material discharge holes.

[0063] Preferably, as Figure 8 shown in the embodiment, a second protrusion 20 is provided on the inner wall surface of the grinding ring. When the swinging hammer 1 moves following the grinding disc, the flared structure passes by the second protrusion 20 and makes the second protrusion 20 inserted into the flared structure. When the flared structure passes by the second protrusion 20, it can cooperate with the second protrusion 20 to form a cutting effect.

[0064] In the present invention, by providing a first cutting part on the swinging hammer, when the swinging hammer is arranged in the grinder, the swinging hammer swings, and the first cutting part on the swinging hammer cooperates with the second cutting parts on the grinding ring and the grinding disc to efficiently crush and cut the object to be processed in the grinder, making the object to be processed smaller, the substances containing long fibers are cut, and the long fibers become short fibers, improving the efficiency of crushing and cutting, avoiding the entanglement of long fibers with the components in the grinder, and ensuring the stable and efficient operation of the grinder.
