[0015] A method for using a particle extrusion cylinder that is easy to feed materials, the method comprising the following steps: The first step: First, fix the cylinder body outside the material extrusion mechanism of the particle extruder, then align the feeding port of the material extrusion mechanism with the inner wall of the cylinder, and then connect the outer wall of the cylinder to the cutting end of the material discharging mechanism. The second step: First, rotate the material extrusion mechanism. At this time, the raw materials are thrown out by centrifugal force from the feeding port and move to the feeding port. The excess raw materials outside the feeding port are sheared by the wall angle and accumulate between the feeding port and the feeding port. The material extrusion mechanism continues to rotate, and the raw materials outside the feeding port are pushed into the feeding port by the subsequent thrown raw materials, so that the raw materials in the feeding port move forward towards the extrusion inlet, and then the raw materials are further extruded forward until they move into the extrusion outlet. In this process, the raw materials are extruded and compacted by the extrusion wall with a gradually decreasing diameter. The raw materials then enter the forming section from the extrusion outlet, making the diameter of the raw materials the same size, and then the raw materials move from the forming section to the discharge port, and the raw materials then reach the outside of the outer wall of the cylinder from the discharge port. The third step: First, rotate the material discharging mechanism around the center of the outer wall of the cylinder. The cutting end contacts the outer surface of the outer wall of the cylinder while rotating around the outer wall of the cylinder. The raw materials outside the outer wall of the cylinder are cut off by the cutting end, and the cut raw materials are formed materials. The formed materials fall into the discharging mechanism, and the formed materials then fall from the outlet of the discharging mechanism.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In a particle extrusion cylinder of the present invention that is easy to feed, the extrusion cylinder includes a cylinder body and an extrusion channel. The extrusion channel forms an included angle with the normal line of the cylinder body between 10 degrees and 25 degrees. The extrusion channel includes a feed inlet, an extrusion section, a forming section, and a discharge outlet. The inner wall of the extrusion section is an extrusion wall, and a wall included angle is formed between the extrusion wall and the inner wall of the cylinder. The degree of the wall included angle is between 63 degrees and 78 degrees. During application, raw materials enter from the feed inlet, are gradually compacted under the extrusion of the extrusion wall in the extrusion section, then the raw materials enter the forming section, and finally the raw materials leave the extrusion channel from the discharge outlet. Because the wall included angle is a relatively sharp acute angle, the wall included angle can cut larger raw materials into smaller volumes, so it is convenient for raw materials to enter the extrusion channel, that is, it can bring about an increase in production capacity. When the speeds at which the raw materials are thrown out are different, that is, when the speed of the power source of the raw materials is different, the relative movement speed between the raw materials and the wall included angle is different. The greater this relative speed, the greater the shear force generated by the wall included angle, and the smaller this relative speed, the smaller the shear force generated by the wall included angle. Different shear forces are suitable for raw materials of different hardness (or dryness and wetness) levels. Some raw materials are formed when the shear force is large, and some raw materials are formed when the shear force is small. Therefore, the present invention facilitates the entry of raw materials and can generate different shear forces according to different rotation speeds of the raw materials.

[0017] 2. In a particle extrusion cylinder of the present invention that is easy to feed, the length of the extrusion section is between 50 millimeters and 70 millimeters. An extrusion included angle is formed between the extrusion wall and the normal line of the inner wall of the cylinder, and the degree of this angle is between 1 degree and 3 degrees. During application, the longer the length of the extrusion section, the denser the raw materials are extruded, and the production quality is improved. Therefore, the production quality of the present invention is good.

[0018] 3. In a particle extrusion cylinder of the present invention that is easy to feed, a discharge included angle is formed between the discharge wall and the normal line of the inner wall of the cylinder, and the range of the degree of this included angle is between 4 degrees and 6 degrees. During application, the discharge included angle shows a gradually widening trend, which is convenient for the formed raw materials to escape. Therefore, the present invention is easy to discharge raw materials.

[0019] 4. In a particle extrusion cylinder of the present invention that is easy to feed, the cylinder body is provided with a top connection part and a bottom connection part. A top connection hole is provided on the top connection part, and a bottom connection hole is provided on the bottom connection part. During application, screws can be screwed into the top connection hole and the bottom connection hole to fix the extrusion cylinder. When the extrusion cylinder is fixed, the extrusion process of the raw materials is stable, which is beneficial to improving the production quality. Therefore, the extrusion process of the present invention is stable. BRIEF DESCRIPTION OF THE DRAWINGS

The extrusion section 22 includes an extrusion inlet 221 and an extrusion outlet 222. The extrusion inlet 221 is located at one end of the extrusion section 22 close to the feed inlet 21, and the extrusion outlet 222 is located at one end of the extrusion section 22 far from the feed inlet 21. The diameter of the extrusion section 22 gradually decreases along the direction from the extrusion inlet 221 to the extrusion outlet 222; the extrusion outlet 222 is connected to one end of the forming section 23, the other end of the forming section 23 is connected to the discharge outlet 24, the discharge outlet 24 is located on the cylinder outer wall 12, and the discharge outlet 24 is communicated with the outside of the cylinder outer wall 12; the inner wall of the extrusion section 22 is an extrusion wall 223, and a wall angle 224 is formed between the extrusion wall 223 and the cylinder inner wall 11, and the degree of the wall angle 224 is between 63 degrees and 78 degrees.

[0045] A method for using an easily fed particle extrusion cylinder, the method includes the following steps: The first step: First, fix the cylinder body 1 outside the material extrusion mechanism 5 of the particle extruder, then align the feed port 51 of the material extrusion mechanism 5 with the cylinder inner wall 11, and then connect the cylinder outer wall 12 to the cutting end 61 of the material discharging mechanism 6; Step 2: First, rotate the material extrusion mechanism 5. At this time, the raw materials are thrown out by centrifugal force from the feeding port 51 and move to the feeding port 21. The excess raw materials outside the feeding port 21 are sheared by the wall included angle 224 and accumulate between the feeding port 21 and the feeding port 51. Then the material extrusion mechanism 5 continues to rotate, and the raw materials outside the feeding port 21 are pushed into the feeding port 21 by the subsequent thrown-out raw materials, causing the raw materials in the feeding port 21 to move forward towards the extrusion inlet 221. Then the raw materials are further extruded forward until they move into the extrusion outlet 222. During this process, the raw materials are extruded and compacted by the extrusion wall 223 with a gradually decreasing diameter. The raw materials then enter the forming section 23 from the extrusion outlet 222, making the diameter of the raw materials become the same size. Then the raw materials move from the forming section 23 to the discharge port 24, and then reach the outside of the cylinder outer wall 12 from the discharge port 24; Step 3: First, rotate the material discharging mechanism 6 around the center of the cylinder outer wall 12. The cutting end 61 contacts the outer surface of the cylinder outer wall 12 while rotating around the cylinder outer wall 12. The raw materials outside the cylinder outer wall 12 are cut by the cutting end 61, and the cut raw materials are formed materials. The formed materials fall into the discharging mechanism 7, and then the formed materials fall from the outlet 71 of the discharging mechanism 7.

[0046] Example 2: The basic content is the same as that of Example 1, except that: Please refer to Figure 1 — Figure 9 The length of the extrusion section 22 is between 50 mm and 70 mm. An extrusion included angle 225 is formed between the extrusion wall 223 and the normal line of the cylinder inner wall 11, and the degree of the extrusion included angle 225 is between 1° and 3°.

[0047] During application, the raw materials first enter from the extrusion inlet 221 and then enter the forming section 23 from the extrusion outlet 222. During this process, due to the existence of the extrusion included angle 225, the diameter of the extrusion inlet 221 is larger than that of the extrusion outlet 222, that is, the raw materials are gradually extruded and become smaller during the movement. The more tightly the raw materials are extruded, the better their quality. If the length of the extrusion section 22 is less than 50 mm, the extrusion process of the raw materials is shorter, and the raw materials are relatively loose, which is not conducive to subsequent use. If the length of the extrusion section 22 is greater than 70 mm, although the extrusion and compaction process of the raw materials is longer, the overall quality of the extrusion cylinder increases, which is not conducive to the use of the extrusion cylinder. Therefore, it is better when the length of the extrusion section 22 is between 50 mm and 70 mm.

[0048] Example 3: The basic content is the same as that of Example 1, except that: Please refer to Figure 1 — Figure 9, the length of the discharging section 26 is between 4 mm and 12 mm. The discharging section 26 includes a discharging wall 263, and a discharging angle 264 is formed between the discharging wall 263 and the normal line of the inner wall 11 of the cylinder. The degree range of the discharging angle 264 is between 4 degrees and 6 degrees. The length of the forming section 23 is between 5 and 8 mm.

[0049] During application, the raw material first enters the forming section 23 from the extrusion outlet 222. The forming section 23 helps the raw material to become a stable diameter, which is beneficial to the forming of the raw material. Then the raw material enters the discharging inlet 261 from the forming section 23, and then the raw material moves from the discharging inlet 261 to the discharging outlet 262. During this process, the raw material will maintain the previous diameter. Due to the existence of the discharging angle 264, the diameter of the discharging outlet 262 is larger than that of the discharging inlet 261, that is, the discharging section 26 has an expanding trend, that is, the diameter of the discharging section 26 gradually becomes larger than the diameter of the raw material. Therefore, the discharging section 26 can facilitate the discharge of the raw material.

[0050] Example 4: The basic content is the same as that of Example 1, the difference is: Please refer to Figure 1 — Figure 10 , a top connection part 3 is arranged at the top of the cylinder body 1, and the diameter of the top connection part 3 gradually becomes larger in the direction gradually away from the cylinder body 1; a bottom connection part 4 is arranged at the bottom of the cylinder body 1; the diameter of the bottom connection part 4 gradually becomes larger in the direction gradually away from the cylinder body 1. A top connection hole 31 is arranged on the top connection part 3, and the top connection hole 31 is a counterbore with a one-way opening upward of the top connection part 3, and the inner surface of the top connection hole 31 is a threaded structure; a bottom connection hole 41 is arranged on the bottom connection part 4, and the bottom connection hole 41 is a counterbore with a one-way opening downward of the bottom connection part 4, and the inner surface of the bottom connection hole 41 is a threaded structure.

[0051] During application, first screw a screw into the top connection hole 31, and then screw a screw into the bottom connection hole 41, then the cylinder body 1 can be fixed. When the cylinder body 1 is fixed, the processes of the entry, extrusion and output of the raw material are relatively stable, so the production quality can be improved.

[0052] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. Any equivalent modification or change made by those of ordinary skill in the art according to the disclosed content of the present invention should be included in the protection scope recorded in the claims.

10. A method for using a particle extrusion cylinder that is easy to feed as described in claim 1, characterized in that: The usage method includes the following steps: The first step: First, fix the cylinder body (1) outside the feeding mechanism (5) of the granule extruder, then align the feeding port (51) of the feeding mechanism (5) with the inner wall (11) of the cylinder, and then connect the outer wall (12) of the cylinder with the cutting end (61) of the material discharging mechanism (6); The second step: First, rotate the feeding mechanism (5). At this time, the raw materials are thrown out by centrifugal force from the feeding port (51) and move to the feeding port (21). The excess raw materials outside the feeding port (21) are sheared by the wall included angle (224) and accumulate between the feeding port (21) and the feeding port (51). The feeding mechanism (5) continues to rotate, and the raw materials outside the feeding port (21) are pushed into the feeding port (21) by the subsequent thrown-out raw materials, so that the raw materials in the feeding port (21) move forward towards the extrusion inlet (221), and then the raw materials are further extruded forward until they move into the extrusion outlet (222). In this process, the raw materials are extruded and compacted by the extrusion wall (223) with a gradually decreasing diameter. The raw materials then enter the forming section (23) from the extrusion outlet (222), making the diameter of the raw materials the same size, and then the raw materials move from the forming section (23) to the discharge port (24), and then the raw materials reach the outside of the outer wall (12) of the cylinder; The third step: First, rotate the material discharging mechanism (6) around the center of the outer wall (12) of the cylinder. The cutting end (61) contacts the outer surface of the outer wall (12) while rotating around the outer wall (12) of the cylinder. The raw materials outside the outer wall (12) of the cylinder are cut by the cutting end (61), and the cut raw materials are formed materials. The formed materials fall into the discharging mechanism (7), and the formed materials then fall from the outlet (71) of the discharging mechanism (7).
