Description

Technical Field

[0001] This utility model relates to the field of silicone production technology, specifically to a raw material mixing device for silicone production. Background Technology

[0002] In the industrial production of silicone products, raw material mixing is one of the key processes that determines product quality. Silicone raw materials are usually composed of silicone rubber raw rubber, reinforcing fillers, plasticizers, vulcanizing agents and various functional additives. The uniformity of dispersion of each component directly affects the physical and mechanical properties, weather resistance and vulcanization molding effect of silicone products.

[0003] However, existing technologies are usually inefficient in stirring and mixing during use, and the raw materials remaining on the inner wall of the mixing tank are not easy to clean, which affects the continued use of the equipment. Therefore, a raw material mixing device for silicone production has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide a raw material mixing device for silicone production, in order to solve the problems mentioned in the background art, such as low mixing efficiency of existing stirring devices and difficulty in cleaning the raw materials remaining on the inner wall of the mixing tank.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material mixing device for silicone production, comprising a shell, an inner shell fixedly connected inside the shell, a heating wire fixedly connected between the shell and the inner shell, a motor fixedly connected to one side of the shell, a rotating shaft fixedly connected to the output shaft of the motor via a coupling, the inner surface of the shell rotatably connected to the outer surface of the rotating shaft, two rotating wheels fixedly connected to the outer surface of the rotating shaft, a second hinge fixedly connected between the two rotating wheels, the outer surface of the second hinge fixedly connected to the outer surface of the rotating shaft, a first hinge fixedly connected between the two rotating wheels, the outer surface of the first hinge slidingly connected to the inner wall of the inner shell, a first cover hinged to the upper surface of the shell, and a handle fixedly connected to the upper surface of the first cover.

[0006] Preferably, a material feeding box is fixedly connected to the upper surface of the first cover, and a second cover is hinged to the upper surface of the material feeding box.

[0007] Preferably, a limiting post is fixedly connected to one side of the feeding box, and a rotating rod is rotatably connected inside the limiting post.

[0008] Preferably, a torsion spring is fixedly connected to the outer surface of the rotating rod, and the outer surface of the torsion spring is fixedly connected to the inner wall of the limiting post.

[0009] Preferably, a rotating block is fixedly connected to the outer surface of the rotating rod, and a groove is formed on the outer surface of the rotating block.

[0010] Preferably, the inside of the feeding box is provided with a sliding groove, the inner wall of the sliding groove is rotatably connected to the outer surface of the rotating block, and one end of the rotating rod is fixedly connected to a rotating disk.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This raw material mixing device for silicone production involves placing the material inside the inner shell, starting the motor, and then rotating the rotating shaft. The rotating shaft drives the second hinge and the rotating wheel to rotate, which in turn drives the first hinge to rotate. The first hinge, in contact with and rotating within the inner shell, scrapes the material adhering to the bottom wall of the inner shell, while simultaneously stirring the material near the inner shell and moving it to the left. Meanwhile, the second hinge, located in the middle, moves the material in the middle to the right. Under the combined action of the second hinge and the first hinge, the material tumbles and moves between the inside and outside, improving mixing efficiency. Simultaneously, an electric heating wire is energized to heat the inner shell, increasing the temperature and fusion efficiency of the material inside. This effectively reduces material adhesion to the inner wall of the device while simultaneously improving mixing efficiency. Attached Figure Description

A first cover 2 is hinged to the upper surface of the outer shell 1, and a handle 3 is fixedly connected to the upper surface of the first cover 2. In use, materials are placed inside the inner shell 1. Inside the shell 10, the motor 7 is started, driving the rotating shaft 16 to rotate. The rotating shaft 16 drives the second hinge 15 and the rotating wheel 17 to rotate, further driving the first hinge 14 to rotate. At this time, the first hinge 14 contacts the inner shell 10 and rotates, scraping the material adhering to the bottom wall of the inner shell 10. At the same time, it stirs the material near the inner shell 10 and moves the material to the left. Meanwhile, the second hinge 15 in the middle position drives the material in the middle position to the right. At this time, the material inside and outside is tumbled and stirred under the combined action of the second hinge 15 and the first hinge 14, improving the stirring efficiency. At the same time, the heating wire 9 is energized to heat the inner shell 10, increasing the temperature and fusion efficiency of the material inside the inner shell 10, which further accelerates the mixing efficiency of the material.

[0022] The upper surface of the first cover 2 is fixedly connected to the feeding box 4, and the upper surface of the feeding box 4 is hinged to the second cover 5. The feeding box 4 is used to facilitate the addition of powder.

[0023] One side of the material feeding box 4 is fixedly connected to a limiting post 8, and a rotating rod 19 is rotatably connected inside the limiting post 8. The rotating rod 19 facilitates the rotation of the rotating block 11.

[0024] Among them, a torsion spring 18 is fixedly connected to the outer surface of the rotating rod 19, and the outer surface of the torsion spring 18 is fixedly connected to the inner wall of the limiting post 8. The torsion spring 18 is used to facilitate the reset of the rotating block 11.

[0025] Among them, a rotating block 11 is fixedly connected to the outer surface of the rotating rod 19, and a groove 12 is provided on the outer surface of the rotating block 11. The groove 12 facilitates the placement and feeding of powder into the inner shell 10.

[0026] The material box 4 has a groove 13 inside, and the inner wall of the groove 13 is rotatably connected to the outer surface of the rotating block 11. One end of the rotating rod 19 is fixedly connected to the rotating disk 6, which facilitates the rotation of the rotating block 11.

[0027] The motor is existing technology and will not be discussed in detail here. The components that match the motor include connecting wires, power supply, and microcontroller, which are also existing structures and will not be discussed in detail here.

[0028] Working principle: First, open the first cover 2 and place the material inside the inner shell 10. Then, start the motor 7, which drives the rotating shaft 16 to rotate. The rotating shaft 16 drives the second hinge 15 and the rotating wheel 17 to rotate, further driving the first hinge 14 to rotate. At this time, the first hinge 14 contacts the inner shell 10 and rotates, scraping the material adhering to the bottom wall of the inner shell 10. At the same time, it stirs the material near the inner shell 10 and moves the material to the left. Meanwhile, the second hinge 15, located in the middle, moves the material in the middle to the right. At this time, under the combined action of the second hinge 15 and the first hinge 14, the material inside and outside is tumbled and stirred, improving the stirring efficiency. At the same time, the heating wire 9 is energized, heating the inner shell 10 and increasing the stirring efficiency. The temperature and fusion efficiency of the material inside shell 10 are monitored. Then, the second cover 5 is opened, and the powder to be added is added into the material box 4. The powder slides into the groove 12. Then, the rotating disk 6 is rotated, which drives the rotating rod 19 to rotate, further driving the rotating block 11 to rotate. At the same time, the torsion spring 18 undergoes elastic deformation until the rotating block 11 rotates half a turn, and the groove 12 is placed downwards. At this time, the powder added to the groove 12 enters the interior of the inner shell 10. Then, the rotating disk 6 is released, the torsion spring 18 returns to its original position, and the rotating block 11 is rotated, so that the groove 12 is placed upwards again. This ensures that the powder inside the inner shell 10 is fused and does not leak out, preventing powder from scattering and reducing the impact on the performance of the silicone raw material caused by powder leakage. At the same time, it effectively prevents pollution to the processing environment and equipment surface.
