DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0022] Reference Figure 1-Figure 5 , a novel extrusion granulation device, comprising;

[0023] The storage barrel 2 is used for storing materials.

[0024] A granulation assembly 1 is located below a material storage barrel 2 and is used for extruding and granulating materials. The granulation assembly 1 includes a cylindrical granulation barrel 101 with mesh holes on the side wall, a first shaft rod 103 at the output end extending to a first motor 102 inside the granulation barrel 101, and an extrusion blade 104 fixed on the first shaft rod 103 and located inside the granulation barrel 101.

[0025] The conveying component 3 is located between the storage barrel 2 and the granulating component 1, and is used to convey the material inside the storage barrel 2 to the inside of the granulating barrel 101. The conveying component 3 includes a sleeve 301 connected between the output port 202 at the bottom of the storage barrel 2 near the edge and the input port at the top of the granulating barrel 101 near the edge, a spiral conveying blade 304 inside the sleeve 301, and a second motor 302 that drives the spiral conveying blade 304 to rotate through a second shaft rod 303.

[0026] like Figures 1 to 5 As shown, the specific granulation process is that the material is poured into the interior of the storage barrel 2 from the top of the storage barrel 2, and the material entering the storage barrel 2 is transported to the interior of the granulation barrel 101 of the granulation assembly 1 through the conveying component 3. The working process of the conveying component 3 is that the second motor 302 drives the second shaft rod 303 to rotate, and the second shaft rod 303 drives the spiral conveying blade 304 to rotate. When the spiral conveying blade 304 rotates, it passes through the sleeve 301 to gradually transport the material from the interior of the storage barrel 2 to the interior of the granulation barrel 101. During the granulation process, the first motor 102 drives the first shaft rod 103 and the extrusion blade 104 to rotate. When the extrusion blade 104 rotates, it pushes the material, so that the material generates centrifugal force to move in the direction close to the inner wall of the granulation barrel 101. When the material adheres to the inner wall of the granulation barrel 101, the extrusion blade 104 interacts with the inner wall of the granulation barrel 101, so that the material passes through the mesh, and the material passing through the mesh falls by its own gravity to form granules. It needs to be further explained that, refer to Figure 4 The second motor 302 is fixed to the upper position of the storage barrel 2 by the fastener 201.

[0027] like Figure 3As shown, in order to enable the side wall mesh of the granulating cylinder 101 to discharge materials quickly, the extrusion blades 104 are arc-shaped, and a plurality of the extrusion blades 104 are evenly spaced and circumferentially arranged along the axis of the first shaft 103 .

[0028] Specifically, the multiple extrusion blades 104 rotate synchronously to push and extrude the material inside the granulation cylinder 101, so that the material is discharged from the side wall of the granulation cylinder 101 in multiple directions. It should be further explained that, referring to Figure 1 and Figure 4 As shown, in order for the inside of the granulating cylinder 101 to evenly receive the material from the inside of the storage cylinder 2 , a plurality of corresponding conveying components 3 should also be provided to ensure that the material in each area inside the granulating cylinder 101 is evenly filled.

[0029] Further, such as Figure 4 As shown, a third motor 203 is further arranged above the material storage barrel 2 , and an output end of the third motor 203 is connected to a material-dispensing blade 204 at the bottom of the material storage barrel 2 via a third shaft 205 .

[0030] Specifically, the output end of the third motor 203 is connected to the material-discharging blade 204 through the third shaft 205. When the material-discharging blade 204 rotates, it can push the material at the central position inside the storage barrel 2 to the output port 202 at the edge position of the storage barrel 2, so as to facilitate the material to enter the interior of the conveying component 3.

[0031] Further, such as Figure 1 and Figure 5 As shown, it also includes a cutting assembly 4 attached to the outside of the granulating barrel 101, and the cutting assembly 4 includes a cutting blade 402 attached to the outside of the granulating barrel 101 and capable of moving up and down along the granulating barrel 101, and a telescopic rod 401 for driving the cutting blade 402 to move up and down, and the top of the telescopic rod 401 is fixed to the outside of the storage barrel 2.

[0032] like Figure 1 and Figure 5 As shown, when the material with high viscosity is squeezed by the squeezing blade 104 and passes through the mesh, it forms a long strip. The telescopic rod 401 drives the cutting blade 402 to move up and down to cut the long strip material, so that the material forms particles.

[0033] Further, such as Figure 1 and Figure 4 As shown, a chassis 5 is also provided at the bottom of the granulating cylinder 101, and a receiving tray 501 is also provided between the granulating cylinder 101 and the chassis 5. The receiving tray 501 is inclined, and a discharge port 502 is opened at the lowest position of the inclined receiving tray 501.

[0034] Specifically, a bottom plate 5 is provided at the bottom of the granulating cylinder 101 , which can be stably placed on the ground. The receiving tray 501 can support the fallen granular materials and discharge them from the discharge port 502 .

[0035] Furthermore, the height of the cutting blade 402 is consistent with the height of the mesh holes on the side wall of the granulating cylinder 101 .

[0036] Among them, Figure 1 and Figure 5 As shown, the height of the cutting blade 402 is consistent with the height of the mesh, so that when the cutting blade 402 is driven by the telescopic rod 401 to move downward, the outside of the mesh is blocked, so that the mesh stops discharging material. At this time, the extruded blade 104 continues to squeeze the material into the inside of the mesh, making the material inside the mesh compact, thereby preventing the produced particles from being loose.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
