Description

Technical Field

[0001] This utility model relates to the field of rubber product processing, and in particular to an automated mixing and stirring equipment for rubber products. Background Technology

[0002] Rubber products are an indispensable basic material in modern industry, widely used in tires, seals, hoses, belts and many other fields. In the production process of rubber products, mixing is a crucial step. Its purpose is to fully mix and disperse raw rubber with various compounding agents under mechanical action to produce a compound with specific properties and uniform composition.

[0003] However, rubber blocks are highly elastic and sticky. When they fall from the hopper or conveyor belt into the feed inlet, they are easily stuck due to mutual squeezing, sticking, or friction with the inner wall of the feed inlet. As subsequent materials are continuously fed in, the stuck rubber blocks will gradually accumulate and compact, forming material arches or bridges, which will partially or completely block the feed channel. This not only prolongs the feeding time per cycle, but may even require production to be interrupted and manually cleared with tools, which seriously affects the continuous production of the equipment and the overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated rubber product mixing and stirring equipment. Through an extrusion component, the rubber accumulated at the feed inlet is forcefully squeezed downwards into the mixing and stirring chamber, thereby improving overall production efficiency.

[0008] Furthermore, a pressure rod is fixedly connected to the bottom end of the lower pressure block, and a pressure ring is fixedly connected to the bottom end of the pressure rod. The outer wall of the pressure ring is slidably connected to the inner wall of the feed inlet.

[0009] Furthermore, a connecting pipe is fixedly connected to the left end of the feed inlet, a placement chamber is fixedly connected to the left end of the connecting pipe, an electric push rod is fixedly connected to the right end of the placement chamber, a cover is fixedly connected to the drive end of the electric push rod, and the outer wall of the cover is slidably connected to the right end of the inner wall of the placement chamber.

A bottom box 19 is provided at the rear end of the inner wall of the box 1. The bottom box 19 is used to carry out the mixed rubber. A feed inlet 5 is fixedly connected to the top left of the mixing chamber 4. A top box 11 is fixedly connected to the top right of the feed inlet 5. A second motor 22 is fixedly connected to the front end of the outer wall of the top box 11. The drive end of the second motor 22 penetrates the inner wall of the top box 11 and is fixedly connected to a rotating rod 23. A fourth rotating rod 23 is fixedly connected to the outer wall of the rotating rod 23. The fourth rotating plate 25 has an extrusion assembly on its outer wall. The fourth rotating plate 25 is connected to the lower pressure block 15 via the extrusion assembly. The extrusion assembly includes a third rotating plate 24 rotatably connected to the outer wall of the fourth rotating plate 25. A fixed tube 13 is rotatably connected to the outer wall of the third rotating plate 24. First rotating plates 12 are rotatably connected to both the front and rear sides of the fixed tube 13. The top ends of the two first rotating plates 12 are rotatably connected to the top of the top box 11. A second rotating plate 14 is rotatably connected to the outer wall of the fixed tube 13. A lower pressure block 15 is rotatably connected to the bottom end of the second rotating plate 14. The outer wall of the lower pressure block 15 is slidably connected to the bottom end of the outer wall of the top box 11. A pressure rod 10 is fixedly connected to the bottom end of feed inlet 5. A pressure ring 9 is fixedly connected to the bottom end of pressure rod 10. The outer wall of pressure ring 9 is slidably connected to the inner wall of feed inlet 5. A connecting pipe 6 is fixedly connected to the left end of feed inlet 5. A placement chamber 7 is fixedly connected to the left end of connecting pipe 6. An electric push rod 27 is fixedly connected to the right end of placement chamber 7. A cover 28 is fixedly connected to the drive end of electric push rod 27. The outer wall of cover 28 is slidably connected to the right end of inner wall of placement chamber 7. A display screen 8 is fixedly connected to the rear end of outer wall of placement chamber 7. A weighing plate 26 is fixedly connected to the bottom end of placement chamber 7. Weighing plate 26 and display screen 8 are connected by wires. Display screen 8 and electric push rod 27 are connected by wires.

[0019] Specifically, the operator places the rubber raw material into the placement chamber 7, where the weighing plate 26 at the bottom monitors the weight in real time and feeds the data back to the display screen 8 to ensure accurate formulation. After weighing, the electric push rod 27 is activated, pulling the cover 28 to open the channel between the placement chamber 7 and the connecting pipe 6. Under the action of gravity, the raw material slides into the feed inlet 5 through the connecting pipe 6. By starting the first motor 3, the stirring rod 20 is driven to rotate, pre-stirring the small amount of rubber that leaks to the top of the mixing chamber 4. At the same time, the second motor 22 is started, driving the fourth rotating plate 25 to rotate through the rotating rod 23, which in turn pushes the third rotating plate 24 to move horizontally. This horizontal movement is transmitted through the fixed pipe 13, causing the first rotating plate 12 to rotate on the top box 11 and the second rotating plate 14 to press down, so that... The lower pressure block 15 slides down the inner wall of the top box 11 and transmits pressure precisely to the pressure ring 9 through the pressure rod 10. The pressure ring 9 then moves downward in the inner wall of the feed port 5, applying a continuous and powerful downward squeezing force to the accumulated rubber products, ensuring that all materials are forcibly and completely pushed into the mixing chamber 4, eliminating material retention and blockage. Subsequently, the stirring rod 20 rotates and propels axially, performing all-round, high-intensity, and uniform mixing of the materials in the chamber. After mixing is completed, the insert 17 is pulled back to compress the spring 21 and disengage from the discharge port 16, thereby opening the discharge channel. The uniformly mixed rubber products fall into the pull-out bottom box 19 on the inner wall of the box 1 under gravity. Finally, the operator only needs to pull out the bottom box 19 to easily remove the finished product.

[0020] Working principle: The rubber products to be mixed are placed into the placement chamber 7. The weight of the raw materials is transmitted to the display screen 8 through the weighing plate 26 at the bottom of the placement chamber 7. After the weighing data is displayed, the electric push rod 27 is activated, which pulls the cover 28 to open the connection between the placement chamber 7 and the connecting pipe 6, allowing the raw materials to slide into the feed inlet 5 through the connecting pipe 6. Then, the first motor 3 and the second motor 22 are activated. The first motor 3 drives the stirring rod 20 to rotate, stirring the rubber products that leak from the feed inlet 5 onto the top of the mixing chamber 4. The second motor 22 drives the rotating rod 23 to rotate to the right, which in turn drives the fourth rotating plate 25 to rotate to the right. The fourth rotating plate 25 then drives the third rotating plate 24 to move to the right, causing the third rotating plate 24 to drive the first rotating plate 12 to rotate on the top box 11 through the fixed pipe 13. Simultaneously, the movement of the fixed tube 13 causes the second rotating plate 14 to push the lower pressure block 15 downward, which slides downward on the top box 11. Then, the downward pressure of the lower pressure block 15 presses down the pressure ring 9 through the pressure rod 10, causing the pressure ring 9 to slide downward in the inner wall of the feed inlet 5 and squeeze the rubber products accumulated in the feed inlet 5 downward, so that all the rubber products are completely squeezed into the mixing chamber 4. The mixing rod 20 then completely mixes and stirs the products. Then, while the mixing rod 20 is stirring, it is pushed to the right. After the mixing is completed, the insert 17 is pulled backward, so that the insert 17 squeezes the compression spring 21 in the connecting box 18 and causes the insert 17 to leave the discharge port 16. The mixed material slides down through the discharge port 16 into the bottom box 19 set on the inner wall of the box 1. Then, the bottom box 19 is pulled outward to remove the rubber products.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
