Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic production, and specifically refers to a mixing device for producing wear-resistant plastic. Background Art
[0002] Plasticizer is a commonly used chemical additive. Its function is to reduce the viscosity of polymers (such as plastics, coatings, adhesives, cement, etc.), making them easier to process and shape, while changing the physical and chemical properties of the final product. The use of plasticizer can reduce material costs, improve processing performance and the final performance of products.
[0003] During the production of wear-resistant plastic, various raw materials or additives need to be mixed and processed. However, during the stirring and mixing process of various raw materials, the stirring plate can only rotate in one direction, resulting in uneven mixing quality. At the same time, raw materials will adhere to the barrel wall during the stirring process, affecting the mixing effect and increasing the mixing cost. Summary of the Utility Model

[0027] Embodiment 1
[0028] Combined with the attached Figure 1 、 Figures 3 to 5As shown in the figure, a kneading device for producing wear-resistant plastic mass includes a kneading barrel 1. A discharge pipe 2 is provided at the bottom of the kneading barrel 1. A rotating rod 3 is rotatably arranged in the kneading barrel 1. A plurality of groups of stirring assemblies are arranged around the rotating rod 3. One group of the stirring assemblies includes a first stirring blade 4 and a second stirring blade 5 fixedly arranged on the rotating rod 3. The first stirring blade 4 and the second stirring blade 5 are symmetrically arranged and are both inclined. The middle of the rotating rod 3 is connected with a first scraping plate 6 with an inclined surface design through a connecting rod 7. A plurality of air spray holes 8 are arranged on the surface of the first scraping plate 6 close to the inner wall of the kneading barrel 1. An air cavity 9 is communicated inside the rotating rod 3 and the first scraping plate 6 and is communicated with the air spray holes 8. An air bag 10 is arranged on the top surface of the kneading barrel 1. The air bag 10 is connected with the air cavity 9 through an air jetting assembly.
[0029] With the above structure, the symmetrical and inclined arrangement of the first stirring blade 4 and the second stirring blade 5 causes the material to flow between the two components. At the same time, under the continuous rotation of the rotating rod 3, the material is turned and mixed, making the mixing more uniform. The air bag 10 supplies air into the air cavity 9, which is ejected from the air spray holes 8 to blow off the material adhering to the barrel wall and reduce the residue of the material.
[0030] Combined with the attached Figure 1 and Figure 2 As shown in the figure, the top of the rotating rod 3 penetrates through the top surface of the kneading barrel 1 and is fixedly provided with a worm gear 11. Two vertical plates 12 are arranged at the top of the kneading barrel 1. A worm 13 meshing with the worm gear 11 is rotatably arranged between the vertical plates 12. A motor 14 is fixedly arranged on the vertical plates 12. The output end of the motor 14 is connected with the rotating shaft of the worm 13. A protective shell 15 is arranged on the upper surface of the kneading barrel 1. The protective shell 15 covers above the worm gear 11. One side of the protective shell 15 is provided with a feed pipe 16 communicated with the kneading barrel 1.
[0031] With the above structure, the motor 14 drives the worm gear 11 to rotate, so that the worm gear 11 drives the rotating rod 3 to rotate, thereby stirring and mixing the material inside the kneading barrel 1. The setting of the protective shell 15 is used to protect the worm gear 11 and the worm 13 and reduce corrosion or damage caused by the outside world to them.
[0032] Embodiment 2
[0033] On the basis of Embodiment 1, combined with the attached Figure 1 , Figure 2 and Figure 6As shown in the figure, the jet component includes an air pump 17 fixedly arranged on the air bag 10. An air pipe one 18 and an air pipe two 19 are respectively connected to the air pump 17. One end of the air pipe one 18 is communicated with the air bag 10, and one end of the air pipe two 19 penetrates through the protective shell 15 and is communicated with the air cavity 9 through a rotary joint 20. A scraper two 21 is connected to the bottom of the scraper one 6, and one end of the scraper two 21 is fixedly connected to the rotating rod 3. The bottom surface of the scraper two 21 is in contact with the bottom surface of the mixing barrel 1. A plug 22 is inserted into the discharge pipe 2, and the outer diameter of the plug 22 is the same as the inner diameter of the discharge pipe 2.
[0034] With the above structure, the air pump 17 pumps the gas in the air bag 10 to the jet holes 8 for spraying, blowing off the materials adhered to the inner wall of the mixing barrel 1 and reducing the material residue. At the same time, the rotary joint 20 is fixedly connected to the rotating rod 3, and the air pipe two 19 is rotatably connected to the rotary joint 20, ensuring that the air pipe two 19 will not get self-tangled when the rotating rod 3 rotates. The scraper two 21 rotates with the rotating rod 3, scraping the materials accumulated on the bottom surface of the mixing barrel 1 and sweeping them from the discharge pipe 2. The plug 22 is used to seal the bottom of the mixing barrel 1 to prevent the materials from falling during use.
[0035] The specific usage method is as follows:
[0036] Put the mixing raw materials into the mixing barrel 1 from the feed pipe 16. The motor 14 drives the worm 13 to rotate, thereby driving the worm gear 11 to rotate. The rotation of the worm gear 11 causes the rotating rod 3 to rotate accordingly. Under the combined rotation of the stirring blade one 4 and the stirring blade two 5, the raw materials are continuously dispersed and polymerized to make them evenly mixed. At the same time, the air pump 17 pumps the gas in the air bag 10 into the air cavity 9 through the air pipe one 18 and the air pipe two 19, and finally sprays out from the jet holes 8. The raw materials adhered to the barrel wall are blown off by the gas impact force and mixed with the raw materials in the barrel. After mixing is completed, pull out the plug 22, and the scraper two 21 rotates to sweep the materials towards the discharge pipe 2 to discharge them.
[0037] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
