Description

Technical Field

[0001] This utility model relates to the field of plastic mixing machine technology, specifically a dust removal device suitable for plastic mixing machines. Background Technology

[0002] Plastics are polymers made from monomers through addition or condensation polymerization. Microplastics can harm human health. Their resistance to deformation is moderate, falling between that of fibers and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. A mixing machine is required in the plastics production process.

[0003] A plastic mixing mill is a rubber mixing equipment that mixes raw rubber and compounding agents. It can also plasticize natural rubber. Mixing mills are divided into two types: open mixing mills and closed mixing mills.

[0004] When existing mixing machines are in use, dust accumulates inside. This dust affects the quality of the finished plastic during mixing, leading to an increased scrap rate. Therefore, a dust removal device suitable for plastic mixing machines is proposed. Utility Model Content

[0038] In this embodiment, by providing a dust removal mechanism 3, the inside of the mixing cylinder 21 can be dusted before mixing, so as to avoid the dust inside affecting the quality of the plastic after mixing.

[0039] Example 2

[0040] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the surface of the dust collector 31 is fixedly connected to the top surface of the movable plate 33, the bottom surface of the movable plate 33 is slidably connected to the top surface of the base plate 1, and an electric telescopic rod 35 is fixedly installed on the top surface of the base plate 1.

[0045] Example 4

[0046] like Figures 1-5 As shown, based on the same concept as embodiments 1-3 above, this embodiment also proposes that a rotating rod 311 is rotatably provided on the inner left end face of the fixed frame 32 through a bearing seat. Two first pulleys 310 are fixedly sleeved on the surface of the rotating rod 311 and the output end surface of the drive motor 39. The surfaces of the two first pulleys 310 are connected by a first belt drive. The right side of the rotating rod 311 extends through the left side of the baffle 315 to the right side of the baffle 315. Two second pulleys 317 are fixedly sleeved on the surface of the rotating rod 311 and the surface of the rotating tube 316, respectively.

When the rotating tube 316 rotates, it can drive the connecting box 37 and the air outlet 36 to rotate synchronously, thereby removing dust from the inside of the mixing drum 21.

[0048] Example 5

[0049] like Figures 1-5 As shown, based on the same concept as embodiments 1-4 above, this embodiment also proposes that a support plate 22 is fixedly installed on the top surface of the bottom plate 1, the top surface of the support plate 22 is fixedly connected to the surface of the mixing cylinder 21, a stirring motor 25 is fixedly installed on the right side of the mixing cylinder 21, the left side of the output end of the stirring motor 25 extends through the left side of the mixing cylinder 21 into the interior of the mixing cylinder 21, and a stirring rod 26 is fixedly installed on the left side of the output end of the stirring motor 25.

[0050] In this embodiment, the mixing drum 21 and the stirring motor 25 are turned on. After the stirring motor 25 is turned on, the stirring rod 26 can be rotated. When the stirring rod 26 rotates, the raw rubber and compounding agent can be mixed.

[0051] Example 6

[0052] like Figures 1-5 As shown, based on the same concept as embodiments 1-5 above, this embodiment also proposes that a feed hopper 23 is fixedly provided through the surface of the mixing cylinder 21 and extends into the interior of the mixing cylinder 21, and a discharge pipe 24 is fixedly provided through the right side of the mixing cylinder 21 and extends into the interior of the mixing cylinder 21, and a second valve is provided inside the discharge pipe 24.

[0053] In this embodiment, after the mixing is completed, the mixed plastic can be discharged by opening the second valve.

[0054] In use, the electric telescopic rod 35 is activated. When the output end of the electric telescopic rod 35 extends, it drives the moving plate 33 to move synchronously. When the moving plate 33 moves, it drives the dust collector 31 to move. When the dust collector 31 moves to the right, it can extend into the mixing drum 21. When the dust collector 31 moves, it drives the connecting box 37 and the air outlet 36 to move synchronously. When the drive motor 39 is activated, the output end of the drive motor 39 rotates, which drives the impeller 38 to rotate synchronously. When the impeller 38 rotates, it draws external air into the dust collector 31. The air is filtered when it passes through the filter screen 313. The air is then delivered to the connecting box 37 through the connecting pipe 319 and blown into the mixing drum 21 through the air outlet 36, thus removing dust from the inside of the mixing drum 21. When the output end of the drive motor 39 rotates, it drives the rotating rod 311 to rotate through the first pulley 310. When the rotating rod 311 rotates, the rotating tube 316 can be rotated via the second pulley 317. When the rotating tube 316 rotates, it can drive the connecting box 37 and the air outlet 36 to rotate synchronously, thereby removing dust from the inside of the mixing drum 21. After the dust removal is completed, controlling the output end of the electric telescopic rod 35 to retract can move the dust removal drum 31 to the right. When the dust removal drum 31 moves to the right, it can drive the baffle 315 to move synchronously. After the baffle 315 moves to the inner wall of the through groove, the electric telescopic rod 35 is closed, and the baffle 315 can block the through groove. After the dust removal is completed, the raw rubber and compounding agent are transported into the mixing drum 21. Then, by opening the mixing drum 21 and the stirring motor 25, the stirring rod 26 can be rotated after the stirring motor 25 is turned on. When the stirring rod 26 rotates, the raw rubber and compounding agent can be mixed. After the mixing is completed, the mixed plastic can be discharged by opening the second valve.

[0055] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
