[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model embodiment provides an injection molding material preparation device, such as... Figure 1-6As shown, the device includes a main shell 1 and a discharge cylinder 2. A hot air inlet pipe and an exhaust pipe are connected to the surface of the main shell 1. The lower end of the discharge cylinder 2 is connected to the upper surface of the main shell 1. A drying chamber 3 is installed inside the main shell 1. When the drying chamber 3 shakes up and down, it causes the injection molding material inside to shake up and down. The injection molding material then disperses continuously due to inertia, allowing the water vapor generated during drying to be discharged promptly. Two through-hole arc plates 9 are fixedly inserted inside the drying chamber 3. Through-hole inclined plates 10 are fixedly installed on the upper surface of each of the two through-hole arc plates 9. The through-hole inclined plates 10 are fixedly inserted inside the drying chamber 3. Multiple vertically penetrating material channels 11 are opened on the upper surface of the through-hole inclined plates 10. Gaps exist between the two opposite sides of the through-hole arc plates 9 and the left and right inner walls of the drying chamber 3. The two through-hole inclined plates 10 are distributed in an inverted V-shape. Each feed trough 11 has a guide perforated plate 12 fixedly installed on its inner top wall. When the drying box 3 shakes up and down, it drives the material to shake up and down synchronously. When the drying box 3 moves in the opposite direction, the material collides with the drying box 3. The material flows through the feed trough 11 to the space between the perforated arc plate 9 and the drying box 3, which can continuously change the position of the material. One end of the drying box 3 is connected to a telescopic shaft 15. The telescopic shaft 15 has an elastic extension tendency. A block 4 is fixedly sleeved on the outer surface of the telescopic shaft 15. A frame 6 is slidably sleeved on the outer surface of the block 4. A power shaft 5 is set at the axis of the main shell 1. One end of the power shaft 5 located on the outside of the main shell 1 is connected to a motor, which can control the rotation of the telescopic shaft 15. One end of the power shaft 5 is fixed to the frame 6. The other end of the power shaft 5 rotates through the inner wall of the main shell 1. The end of the block 4 away from the power shaft 5 slides through the inner wall of the frame 6.

[0024] An oscillating structure 7 is installed on the side of the sleeve 6 away from the power shaft 5. The oscillating structure 7 is connected to the end of the block 4 located outside the sleeve 6. The oscillating structure 7 includes an oscillating motor 71 and an eccentric rod 72. The eccentric rod 72 is located between the oscillating motor 71 and the sleeve 6. The oscillating motor 71 is fixedly connected to the sleeve 6. One end of the eccentric rod 72 is fixed to the output end of the oscillating motor 71. The other end of the eccentric rod 72 is rotatably inserted into the side of the sleeve 6. A longitudinal frame 73 is fixed to the end of the block 4 away from the power shaft 5. The longitudinal frame 73 is slidably sleeved on the outer surface of the insert shaft 74. The longitudinal frame 73 is set perpendicular to the sleeve 6. The connection point between the longitudinal frame 73 and the block 4 is located at the center of the longitudinal frame 73. When the oscillating motor 71 drives the eccentric rod 72 to rotate, it drives the insert shaft 74 to move within the longitudinal frame 73, allowing for reciprocating motion. The block 4 and the telescopic shaft 15 shake. The bottom surface of the main body shell 1 has a discharge hole 8. The inner ring surface of the main body shell 1 slides in contact with an arc-shaped blocking plate 13. An arc-shaped elastic telescopic rod 14 is fixed on the side of the two arc-shaped blocking plates 13 near the drying chamber 3. The other end of the arc-shaped elastic telescopic rod 14 is fixed to the inner wall of the main body shell 1. The two arc-shaped blocking plates 13 are located at the discharge cylinder 2 and the discharge hole 8, respectively. The end of the arc-shaped blocking plate 13 away from the arc-shaped elastic telescopic rod 14 is a semi-hole structure. The semi-hole structure of the arc-shaped blocking plate 13 is adapted to the outer diameter of the telescopic shaft 15. The telescopic shaft 15, the discharge cylinder 2 and the discharge hole 8 are on the same plane. When the telescopic shaft 15 is not connected to the discharge cylinder 2 and the discharge hole 8, the arc-shaped elastic telescopic rod 14 can extend and push the arc-shaped blocking plate 13 to block the discharge hole 8 and the discharge cylinder 2, respectively.

[0025] Working principle: Material is added into the discharge cylinder 2. When material needs to be added into the drying chamber 3, the power shaft 5 drives the sleeve 6 to rotate, which in turn drives the telescopic shaft 15 to connect with the discharge cylinder 2, allowing material to be added into the drying chamber 3. During drying, the power shaft 5 drives the telescopic shaft 15 to rotate to a horizontal state. Then, the vibration motor 71 drives the insert shaft 74 to slide within the longitudinal frame 73 via the eccentric rod 72, continuously pushing the longitudinal frame 73, the block 4, and the drying chamber 3 to shake up and down. When the drying chamber 3 shakes up and down, it causes the injection molding material inside to shake up and down. Then, the injection molding material continuously disperses under inertia, allowing the water vapor generated during the drying process to be discharged in time. After drying is completed, when the power shaft 5 drives the sleeve 6 to rotate, it drives the telescopic shaft 15 to connect with the discharge hole 8, allowing the material in the drying chamber 3 to be discharged.
