[0029] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.
[0030] At present, in order to facilitate the user to feed materials, an embodiment of the present application proposes an extruder.
[0031] The present application embodiment discloses an extruder. Figure 1 and Figure 2An extruder includes an extruder body 1, a feeding mechanism 2 connected to the extruder body 1, and a storage mechanism 3 connected to the feeding mechanism 2. The extruder body 1 is provided with a feeding barrel 11, the feeding barrel 11 is located at the top of the extruder body 1, the storage mechanism 3 is fixed to the ground, and the storage mechanism 3 includes a storage bin 31 fixed to the ground, the top of the storage bin 31 is open, and the top height of the storage bin 31 is lower than the feeding barrel 11, so that the storage bin 31 is located below the feeding barrel 11. In the embodiment of the present application, the top of the storage bin 31 is close to the feeding barrel 11. It is close to the ground, which is convenient for users to put raw materials into the storage bin 31. One end of the feeding mechanism 2 is connected to the feeding barrel 11, and the other end of the feeding mechanism 2 is connected to the storage bin 31. When the user feeds into the extruder body 1 through the feeding barrel 11, the raw materials are put into the storage bin 31, and the raw materials in the storage bin 31 are transported to the feed barrel 11 through the action of the feeding mechanism 2, and finally the feeding of the extruder is realized. There is no need for users to lift the raw materials to the height of the feed barrel 11, which reduces the workload of users and facilitates users to feed.
[0032] Reference Figure 2 and Figure 3 The feeding mechanism 2 includes a conveying shell 21 connected to the storage bin 31, a cage 22 rotatably connected to the inside of the conveying shell 21, and a feeding motor 23 fixedly connected to the conveying shell 21. The conveying shell 21 and the cage 22 are both inclined. The top of the conveying shell 21 is located above the feeding cylinder 11. A feeding hole 212 is provided at the bottom of the side wall of the conveying shell 21. The feeding hole 212 is close to the bottom of the storage bin 31, so that the raw materials inside the storage bin 31 can enter the inside of the conveying shell 21 from the feeding hole 212. The side wall of the conveying shell 21 is provided with a feeding shell 211. One end of the feeding shell 211 is connected to the conveying shell 21, and the other end of the feeding shell 211 is connected to the feeding cylinder 11. The barrel 11 and the feed shell 211 are connected to the side wall of the conveying shell 21, and the feed shell 211 is inclined. The end of the feed shell 211 connected to the conveying shell 21 is higher than the top of the feed barrel 11, and the end of the feed shell 211 away from the conveying shell 21 is located inside the feed barrel 11. The height of the end of the feed shell 211 located inside the feed barrel 11 is lower than the height of the end of the feed shell 211 connected to the conveying shell 21, so that when the raw material passes through the connection position between the conveying shell 21 and the feed shell 211, the raw material can slide into the inside of the feed barrel 11 under the action of gravity, thereby realizing the purpose of the conveying shell 21 connecting the storage bin 31 and the feed barrel 11, and realizing the purpose of feeding.
[0033] At the same time, refer to Figure 2 and Figure 3The feeding motor 23 is fixedly connected to the top of the conveying shell 21, the axial direction of the rotating shaft of the cage 22 is parallel to the length direction of the conveying shell 21, and the two ends of the cage 22 are rotatably connected to the inner walls of the two ends of the conveying shell 21. The output end of the feeding motor 23 passes through the end of the conveying shell 21 and is coaxially fixedly connected to one end of the cage 22. When the user starts the feeding motor 23, the cage 22 rotates inside the conveying shell 21, so that the raw material at the bottom of the conveying shell 21 is lifted to the top of the conveying shell 21 under the action of the cage 22. When the raw material passes through the connection position between the feeding shell 211 and the conveying shell 21, the raw material slides from the feeding shell 211 to the inside of the feeding barrel 11, completing the feeding of the extruder body 1. The user does not need to manually lift the raw material to the top position of the feeding barrel 11, which reduces the user's workload and facilitates the user's feeding.
[0034] Reference Figure 2 and Figure 4 The material storage mechanism 3 also includes a material accumulation component 32 connected to the inside of the material storage bin 31. The material accumulation component 32 includes a material accumulation motor 321 fixedly connected to the material storage bin 31, a screw 322 rotatably connected to the material storage bin 31, a guide rod 323 fixedly connected to the inside of the material storage bin 31, and a scraper 324 slidably connected to the material storage bin 31. Two opposite side walls of the material storage bin 31 are provided with sliding holes 311, and the length direction of the sliding holes 311 is toward the feed hole 212. The scraper 324 passes through the two sliding holes 311 and is slidably connected to the hole wall of the sliding hole 311, so that the scraper 324 is erected inside the material storage bin 31, so that the sliding of the scraper 324 is more stable. The screw 322 and the guide rod 323 are respectively located outside the sliding hole 311, and the axial direction of the screw 322 and the axial direction of the guide rod 323 are parallel to the length direction of the sliding hole 311. The output shaft of the accumulation motor 321 is coaxially fixedly connected to one end of the screw 322. The screw 322 passes through and is threadedly connected to the scraper 324. The axial direction of the screw 322 is parallel to the movement direction of the scraper 324. The axial direction of the guide rod 323 is parallel to the axial direction of the screw 322. The guide rod 323 passes through and is slidably connected to the scraper 324. The guide rod 323 and the screw 322 are respectively located at the two ends of the scraper 324, which makes the sliding of the scraper 324 more stable, and the scraper 324 moves in the direction close to or away from the conveying shell 21. When the user starts the material accumulation motor 321, the material accumulation motor 321 drives the screw 322 to rotate, and the scraper 324 slides in the direction of the feed hole 212 inside the storage bin 31 under the limitation of the guide rod 323 and the sliding hole 311, so that the raw materials inside the storage bin 31 can be gathered toward the feed hole 212 under the action of the scraper 324, thereby achieving the feeding purpose of the extruder. At the same time, the bottom of the scraper 324 is close to the inner bottom of the storage bin 31, so that the raw materials inside the storage bin 31 can be fully gathered and utilized, thereby reducing the waste of raw materials.
