Description

Technical Field

[0001] This utility model relates to the field of plastic blending technology, specifically to a plastic blending device. Background Technology

[0002] Plastic blending refers to the process of mixing and compounding two or more plastics to form a new, seemingly homogeneous composite system, thereby improving certain properties of the base plastic. Plastic blending is not only an important means of plastic modification, but also an important way to develop new materials with novel properties.

[0003] Chinese Patent Publication No. CN222270844U discloses a plastic blending device, relating to the field of plastic blending technology. The device includes a mixing tank with a sealed bottom cover threaded to its outer surface. A fixed support and a recycling bin are welded to the outer wall of the mixing tank, with the fixed support located below the recycling bin. A guide box is fixedly connected to the top of the mixing tank, and conveying cylinders are welded to both outer surfaces of the guide box. In this plastic blending device, the conveying cylinders allow material from the hopper to be introduced through a discharge valve pipe, and the plastic material can be blown by a feeding fan. During blowing, the plastic material is screened through a filter screen, and larger materials are filtered out and then guided to the recycling bin through a return pipe for recycling. This allows for the subsequent blending of larger plastic materials, preventing variations in material size from affecting the blending effect.

[0004] When using existing plastic blending equipment, the poor fluidity of plastics can easily cause material accumulation during continuous feeding, resulting in uneven blending or requiring a longer mixing time. To address this, we propose a new plastic blending equipment. Utility Model Content

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.

[0027] Please see Figure 1-4A plastic blending device includes a mixing tank 1, a tank cover 2 mounted on top of the mixing tank 1, a fixed cylinder 14 passing through the center of the inside of the tank cover 2, a second connecting bearing 8 installed inside the fixed cylinder 14, a bidirectional mixing motor 15 mounted above the fixed cylinder 14, and a transmission rod 11 mounted on the lower output end of the bidirectional mixing motor 15; the transmission rod 11 is movably connected to the fixed cylinder 14 via the second connecting bearing 8; a mixing stirring rod 9 is mounted on both sides below the transmission rod 11, an auger 10 is mounted on the outer surface of the mixing stirring rod 9, a second gear 21 is mounted on the upper output end of the bidirectional mixing motor 15, a first gear 16 is mounted on the left side of the second gear 21, a feeding trough 13 is opened on the inner and outer sides of the tank cover 2, and two symmetrical feeding holes 12 are opened at the bottom of the feeding trough 13; a connecting plate 18 is mounted above the second gear 21, and a third connecting bearing 17 and a fourth connecting shaft are installed inside the connecting plate 18. The first gear 16 is movably connected to the connecting plate 18 via the fourth connecting bearing 19 and the connecting plate 18 via the third connecting bearing 17. A rotating plate 3 is installed above the bucket lid 2. An installation cylinder 4 passes through the center of the rotating plate 3, and a first connecting bearing 7 is installed on the lower inner wall of the installation cylinder 4. The installation cylinder 4 is movably connected to the fixed cylinder 14 via the first connecting bearing 7, and the rotating plate 3 rotates on the bucket lid 2 via the installation cylinder 4 and the first connecting bearing 7. An internal gear ring 20 is installed on the upper inner wall of the installation cylinder 4. The second gear 21 meshes with the first gear 16, and the first gear 16 meshes with the internal gear ring 20. By setting a rotatable rotating plate 3 to drive the feeding cylinder 5 to rotate, the feeding cylinder 5 can rotate while feeding materials, thereby evenly feeding different plastic materials into the mixing bucket 1 for mixing, making the plastic materials uniformly mixed, and improving mixing efficiency and quality.

[0028] Please see Figure 2 and Figure 5 A plastic blending device includes limiting holes 23 located on both sides of the interior of a rotating plate 3. A feeding cylinder 5 passes through the limiting holes 23, and a limiting ring 6 is installed on the outer surface of the feeding cylinder 5. A movable groove 25 is formed on the inner wall of the limiting holes 23, and a pressure block 22 is movably installed inside the movable groove 25. A fifth connecting bearing 24 is installed inside the pressure block 22, and an adjusting bolt 26 passes through the fifth connecting bearing 24. The adjusting bolt 26 is threadedly connected to the rotating plate 3, and the adjusting bolt 26 is movably connected to the pressure block 22 through the fifth connecting bearing 24. The feeding cylinder 5 is detachably connected to the limiting holes 23 through the pressure block 22, and the bottom of the feeding cylinder 5 contacts the bottom of the feeding trough 13. By setting a detachable feeding cylinder 5, it is possible to replace the feeding cylinder 5 with different feeding ports according to different amounts of plastic material, so that the feeding time of each feeding cylinder 5 is as similar as possible, ensuring more uniform material blending.

[0029] Working principle: When using this plastic blending device, firstly, the feeding cylinder 5 is inserted into the limiting hole 23, so that the limiting ring 6 is on the rotating plate 3. Then, the adjusting bolt 26 is turned to push the pressure block 22 towards the feeding cylinder 5 and into contact with the feeding cylinder 5, thereby pressing the feeding cylinder 5 into the limiting hole 23. The amount of material in the feeding cylinder 5 and the limiting hole 23 depends on the type of plastic being blended, and can be two or more. At this time, the discharge port of the feeding cylinder 5 is located between adjacent feeding holes 12, so that the plastic material inside the feeding cylinder 5 will not fall. Furthermore, the discharge port at the bottom of the feeding cylinder 5 has a different size, which allows for the dispensing of large quantities of plastic material. The plastic material is poured into the feeding cylinder 5 with a large discharge port, and a small amount of plastic material is poured into the feeding cylinder 5 with a small discharge port. Then, the controller controls the mixing bidirectional motor 15 to be powered on. The second gear 21, the first gear 16 and the internal gear ring 20 drive the mounting cylinder 4 to rotate, which in turn drives the rotating plate 3 and the feeding cylinder 5 to rotate. When the discharge port at the bottom of the feeding cylinder 5 rotates to the feeding hole 12, the plastic material will fall into the mixing tank 1. Then, the mixing bidirectional motor 15 drives the mixing rod 9 and the auger 10 to rotate through the transmission rod 11 to stir and mix the plastic material. This is the working principle of the plastic blending device.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
