Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle processing equipment, in particular to a plastic particle homogenizing device. Background Art

[0002] Plastic granules are a very important basic raw material in the plastics industry and are widely used in many fields such as packaging, automobiles, construction, electronics, and medical care. They are usually made by heating and plasticizing the plastic raw materials through an extruder, then extruding them through a die of a specific shape and cutting them into granules of a certain size. In this process, the design and efficiency of the granulation equipment have a decisive influence on the quality of the final product.

[0003] Upon investigation, a Chinese utility model patent discloses a plastic particle homogenizing device (publication number: CN219076177U), including a homogenizing bin, wherein the four sides of the homogenizing bin are connected to support legs, a vertical rotating shaft is provided in the homogenizing bin, and auger blades are provided on the surface of the rotating shaft, and the rotating shaft drives the auger blades to rotate upward, and a stirring structure is provided in the homogenizing bin, the middle of the stirring structure is connected to the rotating shaft and rotates synchronously with the rotating shaft, a driven pulley is connected to the top of the rotating shaft, a motor is provided on one side of the support leg, a driving pulley is provided on the output shaft of the motor, and the driving pulley and the driven pulley are connected for transmission by a transmission belt.

[0004] In the above patent, the stirring structure can quickly stir and mix the plastic particles in the homogenization bin, and the auger blades can turn the plastic particles at the bottom upward during the feeding and conveying process, thereby improving the overall homogenization efficiency and homogenization quality, and avoiding the situation of insufficient homogenization.

They may not be able to be packaged in time, which may ultimately reduce production efficiency.

[0005] Therefore, the present invention provides a plastic particle homogenizing device to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a plastic particle homogenizing device, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the plastic particle homogenizing device includes a base plate 1, a fixing frame 2 fixedly mounted on the base plate 1, a homogenizing tank 3 fixedly mounted on the fixing frame 2, an upper hopper 4 fixedly mounted on the fixing frame 2, an inclined feeding hopper 5 fixedly mounted on one side of the upper hopper 4, and a feeding mechanism arranged on one side of the homogenizing tank 3 for cooling and feeding the plastic particles.

[0027] The feeding mechanism includes a feeding tank 6 fixedly mounted on the base plate 1, an auger 7 rotatably mounted inside the feeding tank 6, a first motor 8 fixedly mounted on the bottom of the feeding tank 6, a feeding box 9 fixedly mounted on the top of the feeding tank 6, a blower 10 fixedly mounted on one side of the feeding box 9, and a feeding pipe 11 fixedly mounted on the other side of the feeding box 9.

[0028] The side of the inclined feeding hopper 5 away from the upper hopper 4 is fixedly installed on the side surface of the feeding tank 6, the output end of the first motor 8 passes through the feeding tank 6, and the output end of the first motor 8 is fixedly connected to one end of the auger 7.

[0029] When the plastic particle homogenizing device is in use, the bottom plate 1 is first placed in a suitable position, and then plastic particles are manually added to the upper hopper 4. The plastic particles enter the inclined feeding hopper 5 from the upper hopper 4, and then enter the feeding tank 6 from the inclined feeding hopper 5. The first motor 8 is started, and the output shaft of the first motor 8 drives the auger 7 to rotate synchronously. The rotation of the auger 7 drives the plastic particles to rise, and preliminary stirring and homogenization are performed during the rising process. In this process, the plastic particles are preliminarily cooled. When the plastic particles enter the feeding box 9, the auger 7 cannot drive the plastic particles to rise. At this time, the blower 10 is started, and the airflow blown by the blower 10 blows the plastic particles into the inside of the feeding pipe 11. The plastic particles are cooled again by the airflow, and the plastic particles enter the interior of the homogenizing tank 3 through the feeding pipe 11 for stirring, and then enter the interior of the upper hopper 4 again through the discharge port at the bottom of the homogenizing tank 3. The plastic particles are cooled and stirred many times through the same process, and the homogenization operation is finally completed.

[0030] Furthermore, in order to avoid the plastic particles from being blocked inside the upper hopper 4 during loading, Figure 1 、 Figure 3 and Figure 5 As shown, the upper hopper 4 is internally rotatably connected to a feed roller 12, and one side of the upper hopper 4 is fixedly connected to a second motor 13, the output end of the second motor 13 passes through the upper hopper 4, and the output end of the second motor 13 is fixedly connected to one end of the feed roller 12.

[0031] When the plastic particle homogenizing device is in use, when plastic particles are added to the interior of the upper hopper 4, the second motor 13 is started, and the output shaft of the second motor 13 drives the feed roller 12 to rotate synchronously. The plastic particles are in the grooves on the feed roller 12, and the rotation of the feed roller 12 drives the plastic particles to rotate synchronously, and finally enter the interior of the inclined feed hopper 5. Thereafter, the plastic particles are fed into the interior of the homogenizing tank 3 through the feeding mechanism for homogenization and stirring. After stirring, the plastic particles enter the interior of the upper hopper 4 again, and the above operation is repeated to finally complete the cooling and homogenization of the plastic particles.

[0032] Among them, in order to facilitate the mixing and breaking up of plastic particles, such as Figure 1 、 Figure 2 and Figure 3 As shown, the interior of the homogenizing tank 3 is rotatably connected to a rotating shaft 14, the side surface of the rotating shaft 14 is rotatably connected to a homogenizing frame 15, the side surfaces of the rotating shaft 14 and the homogenizing frame 15 are fixedly connected to a plurality of stirring blades 16, and the side surface of the rotating shaft 14 is fixedly connected to a driving gear 17.

[0033] A fixing rod 18 is fixedly connected to the interior of the homogenizing tank 3 , and a first driven gear 19 is rotatably connected to the side surface of the fixing rod 18 . The first driven gear 19 is engaged with the driving gear 17 , and a second driven gear 20 is rotatably connected to the side surface of the rotating shaft 14 .

[0034] One side of the second driven gear 20 is fixedly connected to the homogenizing frame 15, the first driven gear 19 is meshed with the second driven gear 20, and the top of the homogenizing tank 3 is fixedly connected to the third motor 21. The movable end of the third motor 21 passes through the homogenizing tank 3, and the movable end of the third motor 21 is fixedly connected to one end of the rotating shaft 14. The side surface of the homogenizing tank 3 is fixedly connected to the discharge pipe 22.

[0035] When the plastic particle homogenizing device is in use, after the plastic particles enter the interior of the homogenizing tank 3 through the feeding mechanism, the third motor 21 is started, and the output shaft of the third motor 21 drives the rotating shaft 14 to rotate synchronously, and the rotation of the rotating shaft 14 drives the driving gear 17 and the stirring blade 16 on the rotating shaft 14 to rotate synchronously, and the driving gear 17 drives the first driven gear 19 meshing therewith to rotate synchronously, and the rotation of the first driven gear 19 drives the second driven gear 20 meshing therewith to rotate synchronously, and finally the driving gear 17 and the second driven gear 20 realize synchronous rotation in opposite directions, and the rotation of the second driven gear 20 drives the homogenizing frame 15 and the stirring blade 16 to rotate synchronously, and finally realizes that the stirring blade 16 on the rotating shaft 14 and the stirring blade 16 on the homogenizing frame 15 rotate in opposite directions, so as to better stir the plastic particles, and the stirred plastic particles re-enter the interior of the upper hopper 4 through the discharge pipe at the bottom of the homogenizing tank 3, and the stirring operation is repeated to realize homogenization of the plastic particles.
