[0028] like Figure 1-Figure 6 As shown, an embodiment of the utility model provides an extrusion granulator, including an extrusion barrel 1 and a cover plate 3, the end of the extrusion barrel 1 is connected to the extrusion equipment to ensure stable extrusion of the material, and also includes: a fixed disk 7 fixedly connected to the extrusion barrel 1, the fixed disk 7 is used to collect the extruded material; an extrusion plate 2 fixedly connected to the extrusion barrel 1, a bidirectional motor 4 is fixedly connected to the cover plate 3, a cutter 5 is fixedly connected to the output end of the bidirectional motor 4, the cutter 5 is fitted with the extrusion plate 2, and the cutter 5 is used to cut the extruded material; a drive unit is arranged at the end of the bidirectional motor 4 away from the cutter 5, a sliding disk 15 is arranged on the drive unit, and the drive unit can drive the sliding disk 15 to reciprocate along the direction of the fixed disk 7.

[0029] In the embodiment provided in the present application, the driving unit includes a rotating shaft 10 fixedly connected to the output end of the bidirectional motor 4, a bidirectional screw 11 is fixedly connected to the rotating shaft 10, a mounting sleeve 12 is sleeved on the bidirectional screw 11, the interior of the mounting sleeve 12 is fixedly connected to a protrusion 19 adapted to the bidirectional screw 11, the exterior of the mounting sleeve 12 is symmetrically fixedly connected to two mounting rods 13, the bottom of the mounting rod 13 is fixedly connected to a telescopic rod 14, and a sliding plate 15 is fixedly connected to the bottom end of the telescopic rod 14.

[0030] The specific structure of the bidirectional motor 4 can refer to the technical solutions in the prior art. Those skilled in the art will know that it will not be elaborated here. The bidirectional motor 4 drives the rotating shaft 10 and the bidirectional screw 11 to rotate, and under the action of the protrusion 19, the mounting sleeve 12 is driven to reciprocate on the bidirectional screw 11, thereby driving the sliding disk 15 to move through the mounting rod 13 and the telescopic rod 14. During the movement of the sliding disk 15, the telescopic rod 14 can adapt to the height of the sliding disk 15 to ensure the stability of the movement of the sliding disk 15.

[0031] In the embodiment provided in the present application, a plurality of first rounding grooves 8 are provided on the fixed disk 7, and a plurality of second rounding grooves 16 are provided on a side of the sliding disk 15 close to the fixed disk 7, and the first rounding grooves 8 are matched with the second rounding grooves 16.

[0032] The first rounding groove 8 and the second rounding groove 16 are both semicircular. When the material falls into the first rounding groove 8, the material can be rounded through the relative movement between the first rounding groove 8 and the second rounding groove 16. The fallen residue can be adsorbed in the larger material during the rounding process, and the larger material can be cut into smaller sizes by the first rounding groove 8 and the second rounding groove 16, thereby ensuring the uniformity of the material size. The number of the first rounding groove 8 and the second rounding groove 16 is not limited here, as long as it can meet the rounding requirements of the cut material.

[0033] In the embodiment provided by the present application, there are also two slide grooves 17 symmetrically opened on the side of the sliding plate 15 close to the fixed plate 7, and two positioning blocks 18 are symmetrically fixedly connected to the side of the fixed plate 7 close to the sliding plate 15. The positioning blocks 18 are located in the slide grooves 17, and the sides of the positioning blocks 18 and the slide grooves 17 close to each other are both inclined.

[0034] Initially, the sliding disk 15 is aligned with the fixed disk 7. When the sliding disk 15 and the fixed disk 7 move relative to each other, the material can be rolled into a ball. When the end of the chute 17 moves to the positioning block 18, the sliding disk 15 can move upward along the fixed disk 7 under the action of the positioning block 18, so that the material after rolling will fall from the first rolling groove 8, and the staff can collect the material through the bottom of the first rolling groove 8.

[0035] In the embodiment provided in the present application, a plurality of holes are formed through the extrusion plate 2 , and the diameter of the holes is larger than the diameter of the first rounding groove 8 and the second rounding groove 16 .

[0036] When the material is extruded, after the material contacts the extrusion plate 2, under the action of greater pressure, part of the material is squeezed through the holes of the extrusion plate 2 to the other side, and the extruded material is cut into particles under the action of the cutter 5. It should be explained that there is pressure between the cut material and the first rounding groove 8 and the second rounding groove 16. When the first rounding groove 8 and the second rounding groove 16 move relative to each other, since the material is softer at this time, its shape can be changed by the first rounding groove 8 and the second rounding groove 16 to achieve rounding.

[0037] The embodiment provided in the present application further includes a bracket 9 fixedly connected to the fixed plate 7 , and the bracket 9 is rotatably connected to the rotating shaft 10 .

[0038] The shape of the bracket 9 is not limited here, as long as the end of the rotating shaft 10 can be limited to prevent the damage of the equipment due to position deviation when the rotating shaft 10 rotates.

[0039] In the embodiment provided in the present application, there is also a discharge hole 6 provided at the bottom of the extrusion cylinder 1 , the discharge hole 6 is connected to the first rounding groove 8 , and the side of the fixed plate 7 close to the discharge hole 6 is inclined.

[0040] The cut material will fall to the bottom of the extrusion barrel 1, and finally fall into the first rounding groove 8 through the discharge hole 6. Since the side of the fixed plate 7 close to the discharge hole 6 is inclined, the material can be prevented from accumulating in the extrusion barrel 1, so that the cut material can fall into the first rounding groove 8.

[0041] The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
