Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices, and in particular to a raw material mixing device for engineering plastics processing. Background Technology

[0002] Plastics are high molecular weight compounds formed by polymerizing monomers through addition or condensation reactions. They are commonly known as plastics or resins and their composition and shape can be freely changed. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. In the plastic processing process, various plastic raw materials need to be melted and added to a stirring device for mixing.

[0003] During the discharge process, plastic requires considerable force to agitate it, which can cause the mixing tank to shake and become unstable. In addition, the raw materials tend to settle at the bottom during mixing, resulting in uneven mixing. Utility Model Content

The scraper ring 15 is mainly used to scrape off the material adhering inside the mixing tank 2; the bottom of the mixing tank 2 is provided with a discharge chamber 9; a spiral feeding rod 10 is rotatably installed in the discharge chamber 9; the bottom of the discharge chamber 9 facing the discharge direction is provided with a discharge port 11; the base 1 is provided with a fixing mechanism 12 for fixing the mixing tank 2.

[0030] The top cover 3 includes a first top cover 31 and a second top cover 32; the first top cover 31 is fixed above the mixing tank 2; the second top cover 32 is hinged to the first top cover 31; the second top cover 32 is provided with a handle 13.

[0031] The stirring blade 6 is oriented downwards; the spiral blade 7 is oriented upwards.

[0032] The moving component 8 includes a second rotating motor 81 and a screw 82;

[0033] The second rotating motor 81 is provided above the first top cover 31; the output end of the second rotating motor 81 is connected to the screw 82; a moving block is threadedly connected to the screw 82, and the moving block is fixedly connected to the scraper ring 15.

[0034] The side wall of the discharge chamber 9 is provided with a third rotary motor 14 that drives the spiral feed rod 10 to rotate.

[0035] The fixing mechanism 12 includes a fixing plate 121, a threaded groove 122, an adjusting screw 123, a rotating handle 124, a telescopic rod 125, a clamping plate 126, and a spring 127.

[0036] A pair of fixing plates 121 are fixed on the base 1, located on the left and right sides of the mixing tank 2; the fixing plate 121 has a threaded groove 122 in the middle, and the threaded groove 122 is threadedly connected to the adjusting screw 123; the adjusting screw 123 has a rotating handle 124 on the far right and a telescopic rod 125 inserted on the far left; the telescopic rod 125 is connected to the clamping plate 126 on the left side; the clamping plate 126 has a rubber strip on the side near the mixing tank 2; the telescopic rod 125 is fitted with a spring 127.

[0037] Working principle: Pull handle 13 to open the second top cover 32, pour the required raw materials into the mixing tank 2, then close the second top cover 32, turn on the first rotating motor 4, so that the first rotating motor 4 drives the stirring shaft 5 to rotate, and then the stirring blades 6 of the upper part of the stirring shaft 5 stir the raw materials in the mixing tank 2 evenly and make them sink to the middle of the mixing tank 2. The spiral blades 7 of the lower part prevent the raw materials in the mixing tank 2 from settling to the bottom of the mixing tank 2, and under the action of the spiral blades 7, they also stir them to the middle. This step makes the raw materials fully and evenly mixed inside the mixing tank 2.

[0038] During the mixing process, the second rotating motor 81 is turned on, causing the screw 82 to rotate, which in turn drives the scraper ring 15 to move up and down, thereby scraping the material from the inner wall of the mixing tank 2 and preventing the raw material from clogging the inner wall of the mixing tank 2.

[0039] This utility model, by setting up a fixing mechanism 12, uses the rotating handles 124 at both ends of the adjusting screw 123 to clamp and fix the outer wall of the mixing tank 2 with the fixing blocks on both sides. Simultaneously, when the inside of the mixing tank 2 shakes violently, the spring 127 and the telescopic rod 125 provide a buffering effect.
