Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a modified plastic raw material mixing device. Background Art

The current modified plastic raw material mixing devices are mostly mixers.

[0003] For example, Chinese patent publication number CN216992623U discloses a device for mixing plastic modified masterbatch raw materials, comprising a frame, a stirring box mounted on the frame, a stirring rod disposed in the stirring box, and a first motor connected to the stirring rod. The stirring box is a cylindrical box body, a support shaft is fixedly connected to the outer wall of the middle portion of the stirring box along its radial direction, the support shaft is horizontally arranged and rotatably connected to the frame, a first pulley is coaxially fixed to the support shaft, the frame is fixedly connected to a second motor, the second motor power output shaft is fixedly connected to a second pulley, and the second pulley is connected to the first pulley via a transmission belt. The stirring rod is driven to rotate by the first motor, and as needed, the stirring box is driven to rotate around the axis of the support shaft by the second motor under the action of the pulley assembly, causing the entire stirring box to flip, thereby achieving multi-degree-of-freedom stirring of the masterbatch raw materials, which is beneficial to improving stirring efficiency and stirring uniformity.

[0004] However, the stirring rod of the device rotates unidirectionally to stir and mix the raw materials. When stirring in one direction, it is easy for the raw materials to form a fixed flow pattern during the stirring process, which has a relatively limited dispersion effect on the raw materials, and is prone to agglomeration or stratification, so that some raw materials cannot fully contact and mix, thereby affecting the overall efficiency of uniform mixing. At the same time, it is not convenient to crush and refine the agglomerated raw materials, affecting the overall mixing effect.

[0005] Therefore, it is necessary to provide a modified plastic raw material mixing device to solve the above technical problems. Utility Model Content

When the gear 102 contacts the toothless part on the incomplete gear 101, the length of the set spring 105 is restored, thereby increasing the spring 105 to pull the first convex plate 103 to reset, thereby pulling the shaft 9 to reset, thereby driving the shaft 9 to rotate back and forth in a cycle, thereby driving the first stirring rod 10 to stir the plastic raw material in two directions. The two-way reciprocating stirring method can ensure that the plastic raw material is uniformly mixed during the stirring process. The stirring in two directions makes it easier for the plastic raw material to form uniform particles during the mixing process, avoiding the situation where the local concentration is too high or too low, improving the stirring and mixing effect of the plastic raw material, making the uniform mixing process of the plastic raw material more efficient and fast, and improving the raw material mixing efficiency.

[0027] Further as Figure 4 and Figure 5 As shown, it is worth mentioning that the rolling assembly 2 includes a connecting rod 201 fixed on the side of the shaft 9, and the end of the connecting rod 201 away from the shaft 9 is connected to the bracket 202, and the two ends of the bracket 202 are connected to the rolling roller 203 for rotation together, and the side of the rolling roller 203 is in contact with the inner wall of the processing cylinder 3; in the process of the first stirring rod 10 stirring and mixing the plastic raw materials, the shaft 9 drives the bracket 202 and the rolling roller 203 to rotate synchronously through the connecting rod 201, and due to the pressure contact between the rolling roller 203 and the inner wall of the processing cylinder 3, the rolling roller 203 rotates at the same time, so that the plastic raw materials are rolled by the rotating rolling roller 203 and the inner wall of the processing cylinder 3, and the agglomerated raw materials are crushed and broken, so that the agglomerated raw materials are refined, the agglomerated raw materials in the plastic raw materials are effectively removed, and the plastic raw materials are promoted to be evenly mixed, thereby further improving the efficiency of the uniform mixing of the plastic raw materials.

At this time, the shaft 9 drives the first convex plate 103 to deflect synchronously, thereby stretching the spring 105. When the gear 102 and the incomplete gear 101 have no teeth on the local contact, the length of the set spring 105 is restored, thereby increasing the spring 105 to pull the first convex plate 103 to reset, thereby Pull the shaft 9 to reset, thereby driving the shaft 9 to rotate back and forth in a circular motion, thereby driving the first stirring rod 10 to stir the plastic raw material back and forth in two directions. The two-way reciprocating stirring method can ensure that the plastic raw material is evenly mixed during the stirring process. The stirring in two directions makes it easier for the plastic raw material to form uniform particles during the mixing process. In the process of the first stirring rod 10 stirring and mixing the plastic raw material, the shaft 9 drives the bracket 202 and the rolling roller 203 to rotate synchronously through the connecting rod 201.
