Description

Technical Field

[0002] Injection molding is a common plastic processing method. By injecting the heated and melted plastic material into a mold and cooling it, the required products or parts can be formed. During the injection molding production process, different types of plastic raw materials need to be added to the injection molding machine to produce finished products with different properties and characteristics.

[0003] An injection molding processing batching device mentioned in the existing Chinese patent (authorization announcement number: CN220179990U) can pour different injection molding batches into the batching barrel through the set material distribution barrel, concave plate, adjusting rod, lifting plate and baffle. The quantity of different injection molding batches entering the batching barrel can be adjusted separately, and at the same time, the flow rate of the injection molding batches entering the batching barrel can also be controlled, which is convenient for personnel to adjust the proportion of the injection molding batches. Moreover, the adjustment method of this batching device is relatively simple and convenient for personnel to use.

[0004] When performing injection molding batching currently, different types of plastic particles can be proportioned well and then stirred and mixed by a stirring rod to complete the injection molding batching. However, during the stirring and mixing process, it is not easy to break some larger plastic particles, resulting in uneven heating when they are sent into the injection molding machine for heating and melting later.

[0032] The following is combined with Figures 1-4 The utility model is described in further detail.

[0033] The utility model embodiment discloses an injection molding batching device.

[0034] Reference Figures 1 to 3, An injection molding processing batching device, including a bottom plate 1, a stirring barrel 2 is fixedly connected to the top of the bottom plate 1. The top of the stirring barrel 2 is provided with an opening. A barrel cover 3 is lapped on the top of the stirring barrel 2. A feed pipe 4 is fixedly connected to the top of the barrel cover 3. The feed pipe 4 is communicated with the stirring barrel 2. Above the barrel cover 3, there is a rotating motor 5. The output end of the rotating motor 5 penetrates through the barrel cover 3 and is fixedly connected to a rotating rod 6. The output end of the rotating motor 5 is rotatably connected to the barrel cover 3. On both sides of the rotating rod 6, a number of stirring rods 7 are fixedly connected at equal intervals. A discharge pipe 8 is fixedly connected to the bottom of the stirring barrel 2. The discharge pipe 8 is communicated with the stirring barrel 2. One side of the stirring barrel 2 is fixedly connected to a fixing plate 9. A feeding box 10 is fixedly connected to the top of the fixing plate 9. The feeding box 10 is communicated with the stirring barrel 2. The feeding box 10 is provided with an opening. A crushing mechanism is arranged on the inner bottom wall of the barrel cover 3. A protection mechanism is arranged on the top of the feeding box 10.

[0035] When carrying out injection molding batching, first add the raw materials into the stirring barrel 2 through the feed pipe 4, and then add the injection molding batching into the inside of the stirring barrel 2 through the feeding box 10. At this time, start the rotating motor 5 to drive the rotating rod 6 to rotate. The rotation of the rotating rod 6 makes the stirring rods 7 stir and mix the raw materials inside the stirring barrel 2. After stirring is completed, the raw materials can be transported to the injection molding machine through the discharge pipe 8 for heating and melting, so as to complete the injection molding batching work. The larger plastic particles can be crushed through the crushing mechanism, so that the raw materials can be evenly heated and melted when entering the injection molding machine, improving the quality of the plastic after injection molding. The opening of the feeding box 10 can be protected through the protection mechanism, reducing the risk of impurities, dust and other impurities entering the stirring barrel 2.

[0036] Refer to Figure 2 and Figure 3 , The crushing mechanism includes a filter box 11 fixedly connected to the inner bottom wall of the barrel cover 3. The bottom end of the rotating rod 6 penetrates through the filter box 11. The rotating rod 6 is rotatably arranged with the filter box 11. The top of the filter box 11 is provided with an opening. Inside the filter box 11 on the outer surface of the stirring rod 7, a connecting block 12 is fixedly connected. Blades 13 are fixedly connected to both sides of the connecting block 12.

[0037] Among them, a hydraulic telescopic rod 14 is fixedly connected to the top of the bottom plate 1. A connecting plate 15 is fixedly connected to the top of the hydraulic telescopic rod 14. The bottom of the connecting plate 15 is fixedly connected to the barrel cover 3. The top of the connecting plate 15 is fixedly connected to the rotating motor 5. The output end of the rotating motor 5 penetrates through the connecting plate 15. The output shaft of the rotating motor 5 is rotatably connected to the connecting plate 15.

[0038] In addition, a vibration plate 16 is fixedly connected to one side of the mixing barrel 2, and the vibration plate 16 is set to be L-shaped. A drive motor 17 is fixedly connected to one side of the vibration plate 16. Drive rods 18 are set on both sides of the inside of the mixing barrel 2. The output end of the drive motor 17 passes through the vibration plate 16 and is fixedly connected to one side of the drive rod 18. The output shaft of the drive motor 17 is rotatably connected to the vibration plate 16. The ends of the drive rods 18 on both sides away from the vibration plate 16 pass through the mixing barrel 2 and are fixedly connected to a resistance rod 19. When the resistance rod 19 rotates, it resists the filter box 11.

[0039] In addition, a pulley 1 is fixedly connected to the outer surface of the output shaft of the driving motor 17, and a transmission belt 25 is sleeved on the outer surface of the pulley 1. A pulley 26 is sleeved on the side of the transmission belt 25 away from the pulley 1. The pulley 26 is rotatably connected to the vibration plate 16. A driving rod 18 on the other side penetrates the vibration plate 16 and is fixedly connected to the pulley 26. The driving rod 18 is rotatably connected to the vibration plate.

[0040] After the raw material enters the mixing barrel 2 through the feed pipe 4, the top of the filter box 11 is set to an open shape, so that the plastic raw material enters the filter box 11. At this time, the connecting block 12 is driven to rotate by starting the stirring rod 7, and the connecting block 12 rotates and the blade 13 rotates, thereby rotating and cutting the raw material falling into the filter box 11, and the cut raw material will fall downward through the holes of the filter box 11 into the mixing barrel 2 for mixing and stirring, thereby achieving the purpose of breaking up larger plastic particles for mixing. In the process of cutting the raw material, the driving motor 17 is then started to drive the driving rod 18 to rotate, and the driving rod 18 rotates to drive the resistance rod 19 to strike and vibrate the bottom of the filter box 11, so that the filter box 11 vibrates, and the vibration can be transmitted to the holes of the filter plate, The obstruction in the hole is displaced, so that the filter channel is unblocked again, and the filter box 11 resumes its filtering function. When the resistance rod 19 hits the filter box 11, the drive motor 17 will drive the pulley 1 to rotate, and the rotation of the pulley 1 drives the transmission belt 25 to rotate, and the rotation of the transmission belt 25 drives the pulley 2 26 to rotate, and the rotation of the pulley 2 26 will cause the resistance rod 19 on the other side to hit the filter box 11, thereby increasing the vibration frequency of the filter box 11 and further reducing the risk of blockage of the filter box 11. After the work is completed, the connecting plate 15 can be raised by starting the hydraulic telescopic rod 14, and the raising of the connecting plate 15 can drive the barrel cover 3 to move upward, and the upward movement of the barrel cover 3 will cause the filter box 11 and the rotating rod 6 to move upward, thereby facilitating maintenance and replacement by the staff.

[0041] Reference Figure 1 , Figure 3 and Figure 4 The protection mechanism includes inclined plates 20 fixedly connected to both sides of the charging box 10, a rotating shaft is rotatably connected between the inclined plates 20 on both sides, and a rotating plate 21 is fixedly connected to the outer surface of the rotating shaft.

[0042] Wherein, one side of the inclined plate 20 away from the rotating plate 21 is rotatably connected with a linkage rod 22. The rotating shaft penetrates through the inclined plate 20 and is fixedly connected with the linkage rod 22. A torsion spring 23 is sleeved on the outer surface of the linkage rod 22.

[0043] In addition, a buffer pad 24 is fixedly connected to the bottom of the rotating plate 21, and the buffer pad 24 is adapted to the opening of the feeding box 10.

[0044] When protecting the opening of the feeding box 10, first turn the rotating plate 21 upwards, and then add injection molding ingredients into the feeding box 10. At this time, when the rotating plate 21 flips, it drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the linkage rod 22 to rotate. The rotation of the linkage rod 22 causes the torsion spring 23 to be compressed to generate elastic potential energy. When the injection molding ingredients are added, the elastic potential energy of the torsion spring 23 is released to drive the rotating shaft to rotate, and the rotation of the rotating shaft causes the rotating plate 21 to block the opening at the top of the feeding box, which can effectively reduce the entry of impurities such as sundries and insects into the stirring barrel 2, thereby maintaining the environment inside the stirring barrel 2.

[0045] Working principle: It is added into the stirring barrel 2 through the feeding pipe 4, and then the injection molding ingredients are added into the interior of the stirring barrel 2 through the feeding box 10. At this time, starting the rotating motor 5 drives the rotating rod 6 to rotate. The rotation of the rotating rod 6 causes the stirring rod 7 to stir and mix the raw materials inside the stirring barrel 2. After the stirring is completed, the raw materials can be transported to the injection molding machine through the discharge pipe 8 for heating and melting, thereby completing the injection molding ingredient work. The plastic raw materials enter the filter box 11. At this time, starting the stirring rod 7 drives the connecting block 12 to rotate, and the rotation of the connecting block 12 causes the blade 13 to rotate, thereby rotating and cutting the raw materials falling into the filter box 11. The cut raw materials will fall downward through the holes of the filter box 11 into the stirring barrel 2 for mixing and stirring. When the rotating plate 21 moves downwards, since the buffer pad 24 is made of rubber, the collision sound between the rotating plate 21 and the feeding box 10 can be reduced.
