Description

Technical Field

[0001] The utility model relates to the field of plastic processing, in particular to a plastic mixing and stirring device. Background Art

[0002] Plastics are polymer materials, typically processed from petrochemicals. Their high degree of plasticity and diverse physical properties make them widely used in daily life and industrial production. There are many types of plastics, including polyethylene, polypropylene, and polystyrene, which are commonly used in the manufacture of various products, such as packaging materials, household items, and automotive parts. During the plastics manufacturing process, it is often necessary to mix plastic particles of different types or colors, additives, and fillers to ensure that the final product meets the required performance and appearance. A stirring device effectively and uniformly mixes these ingredients.

[0003] However, due to the characteristics of plastic materials, it often adheres to the inner walls of the mixing tank during the mixing process. When the inner walls need to be cleaned, operators must shut down the equipment, a time-consuming process. This extended cleaning time can affect production schedules, causing subsequent production batches to be delayed, thereby affecting overall production efficiency.

[0004] Therefore, those skilled in the art provide a plastic mixing and stirring device to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a plastic mixing and stirring device. The outer end of the stirring paddle of the utility model is provided with a brush plate which can continuously brush the inner end of the stirring tank.

[0027] Reference Figure 1-Figure 3 , an embodiment provided by the utility model:

[0028] A plastic mixing device comprises a mixing tank 1 and a mixing mechanism 8. A motor 2 is fixedly provided on one side of the upper end of the mixing tank 1, and a No. 1 bevel gear 3 is fixedly provided on the output end of the motor 2. A hollow column 4 is rotatably provided in the middle of the upper end of the mixing tank 1. A No. 2 bevel gear 5 is fixedly sleeved on the outer end of the upper side of the hollow column 4. A connecting pipe 6 is rotatably provided on the upper end of the No. 2 bevel gear 5. A No. 1 gear 7 is fixedly sleeved on the lower end of the hollow column 4. A fixed pipe 9 is fixedly provided on the upper end of the outer side of the mixing tank 1, a feed box 10 is fixedly provided on one side of the fixed pipe 9, a spiral plate 11 is fixedly provided on the inner end of the fixed pipe 9, a discharge port 12 is fixedly provided on the lower end of the mixing tank 1, a support seat 13 is fixedly provided on the lower end of the outer side of the mixing tank 1, the No. 1 bevel gear 3 is meshed with the No. 2 bevel gear 5, and the connecting pipe 6 is rotatably provided on the upper end of the hollow column 4.

[0029] Specifically, after the material is added from the feed box 10, it will first pass through the spiral plate 11, which will first mix the material, and then the material will enter the mixing tank 1 along the fixed tube 9. After turning on the motor 2, since the No. 1 bevel gear 3 is engaged with the No. 2 bevel gear 5, the No. 2 bevel gear 5 will drive the hollow column 4 to rotate, thereby driving the No. 1 gear 7 to rotate. The No. 1 gear 7 can drive the stirring mechanism 8 to fully stir the material, and finally discharge it from the discharge port 12. The initial mixing of the spiral plate 11 and the subsequent sufficient stirring in the mixing tank 1 ensure that plastic materials of different types and compositions can be evenly distributed.

[0030] Reference Figure 4-Figure 7 The stirring mechanism 8 includes a mounting box 801, and four fixed columns 802 are rotatably provided at the inner end of the mounting box 801. The upper ends of the four fixed columns 802 are fixedly sleeved with a number 2 gear 803. The four fixed columns 802 pass through the mounting box 801 and pass to the lower end of the mounting box 801 where a plurality of stirring paddles 804 are fixedly sleeved. The outer ends of the plurality of stirring paddles 804 are fixedly provided with a brush plate 805; the mounting box 801 is fixedly set on the inner side of the stirring tank 1 near the upper end, and the hollow column 4 passes through the mounting box 801 and passes to the inner end of the mounting box 801; the number one gear 7 is rotatably set at the inner end of the mounting box 801, and the four number two gears 803 are rotatably set at the inner end of the mounting box 801; the number one gear 7 is meshed with the four number two gears 803; the plurality of stirring paddles 804 are rotatably set at the inner end of the stirring tank 1, and the plurality of brush plates 805 are in contact with the inner end of the stirring tank 1.

[0031] Specifically, after turning on the motor 2, the No. 1 gear 7 will drive the No. 2 gear 803 to rotate, so that the fixed column 802 can rotate, thereby causing the stirring paddle 804 to rotate, and the brush plate 805 can continuously brush the inner wall of the stirring tank 1, which can prevent the material from adhering to the inner wall, ensure that all materials are evenly stirred, and reduce the risk of product quality fluctuations caused by uneven mixing. The connecting pipe 6 and the hollow column 4 are not connected together, so when the hollow column 4 rotates, the connecting pipe 6 will not rotate. The connecting pipe 6 and the hollow column 4 can add antioxidants, ultraviolet absorbers, plasticizers, etc. into the stirring tank 1 to ensure that they can fully penetrate and mix with other materials, thereby improving the overall performance of the material.

[0032] Working principle: After the material is added from the feed box 10, it will first pass through the spiral plate 11, which will first mix the material. Then the material will enter the mixing tank 1 along the fixed pipe 9. After turning on the motor 2, since the No. 1 bevel gear 3 is engaged with the No. 2 bevel gear 5, the No. 2 bevel gear 5 will drive the hollow column 4 to rotate, thereby driving the No. 1 gear 7 to rotate. The No. 1 gear 7 can drive the stirring mechanism 8 to fully stir the material, and finally discharge it from the discharge port 12;

[0033] Secondly, after turning on the motor 2, the No. 1 gear 7 will drive the No. 2 gear 803 to rotate, so that the fixed column 802 can rotate, thereby causing the stirring paddle 804 to rotate, and the brush plate 805 can continuously scrub the inner wall of the stirring tank 1. The connecting tube 6 and the hollow column 4 are not connected together, so when the hollow column 4 rotates, the connecting tube 6 will not rotate. The connecting tube 6 and the hollow column 4 can add antioxidants, ultraviolet absorbers, plasticizers, etc. into the stirring tank 1, which can improve the performance or processing characteristics of the plastic.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
