Description
Technical Field
[0001] This utility model relates to the field of rubber production equipment, and in particular to an extruder for producing high-styrene rubber. Background Technology
[0002] An extruder is a key type of mechanical equipment that uses the pressure and shear force generated by the rotation of a screw to continuously plasticize, melt, mix, and finally extrude solid materials (such as plastics, rubber, food raw materials, etc.). It is widely used in many industries such as plastics, rubber, chemicals, food, and building materials. Its core function is to transform loose raw materials into continuous products with specific shapes and properties, or to provide a uniform melt for granulation and molding. As the core equipment for "continuous and automated processing" in industrial production, the core value of the extruder lies in its ability to efficiently transform dispersed raw materials into high-quality continuous products through an integrated process of melting, mixing, purification, and molding. This ensures the continuity and stability of production and improves the consistency and performance of the products through precise control.
[0003] Traditional extruders often lack a pre-dehydration process for high-styrene rubber raw materials before they are fed in. This allows excess moisture carried in the raw materials to directly enter the extruder system, which significantly increases the load on the equipment during the dehydration and devolatilization process. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an extruder for the production of high-styrene rubber, which solves the problem of increased devolatilization load caused by the lack of dehydration of raw materials in traditional extruders.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an extruder for producing high-styrene rubber, comprising a base plate, a collection box mounted on the upper surface of the base plate, a mixing box mounted on the upper surface of the collection box, a first motor mounted on the upper surface of the mixing box, a rotating column mounted on the output end of the first motor after penetrating the mixing box, multiple stirring blades mounted on the outer surface of the rotating column, a humidity monitoring module mounted on the inner top wall of the mixing box, a hot air blower mounted on the upper surface of the mixing box, the output end of the hot air blower penetrating the mixing box and extending into the interior of the mixing box, and a valve mounted on the bottom surface of the mixing box.
[0006] As a further technical solution of this utility model, a filter box is installed on the upper surface of the mixing tank, and a feed hopper is installed on the upper surface of the filter box.

[0009] As a further technical solution of this utility model, a round rod is rotatably installed on the inner wall of the crushing box, and a second gear is installed on the outer surface of the round rod. The outer surface of the second gear meshes with the outer surface of the first gear. Crushing rollers are fixedly installed on both the outer surface of the round rod and the outer surface of the rotating rod.
[0010] As a further technical solution of this utility model, a first pump body is installed on the upper surface of the crushing box. The output end of the first pump body extends through the filter box and into the interior of the filter box. The input end of the first pump body is connected to a suction nozzle, and the outer surface of the suction nozzle is connected to the outer surface of the crushing box.
[0011] As a further technical solution of this utility model, a second pump body is installed on the upper surface of the base plate.

[0013] This utility model provides an extruder for producing high-styrene rubber, which has the following advantages compared with the prior art: 1. This design is an extruder for the production of high-styrene rubber. Hot air is continuously injected by a hot air blower. In conjunction with a rotating column and stirring blades driven by a first motor, the raw material can fully contact the hot air flow during tumbling, accelerating the evaporation of moisture. At the same time, the humidity monitoring module monitors the humidity inside the chamber in real time to ensure that the moisture content of the raw material meets the standard before entering the subsequent process. This avoids the problem of increased devolatilization burden caused by undried raw material entering the extruder directly, thus ensuring product quality from the source.
[0014] 2. This design is for an extruder used in the production of high-styrene rubber. A second motor drives the filter plate to vibrate at high frequency, allowing particles that meet the particle size requirements to enter the mixing chamber smoothly. Oversized particles are intercepted and guided to the crushing chamber. A third motor drives two crushing rollers to form opposing shearing forces, crushing large high-styrene rubber particles into fine particles. The crushed particles are then pumped to the filter chamber by the first pump through the suction nozzle and re-screened by the filter plate to ensure that all raw materials entering the mixing chamber meet the particle size standard, ensuring more uniform heating during subsequent drying.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-4This utility model provides a technical solution for an extruder used in the production of high-styrene rubber: it includes a base plate 1, a collection box 2 installed on the upper surface of the base plate 1, a mixing box 3 installed on the upper surface of the collection box 2, and a first motor 4 installed on the upper surface of the mixing box 3 to provide power for mixing, driving the rotating column 5 and the mixing blades 6 to rotate, so that the raw materials are evenly turned over in the box, ensuring consistent heating and drying effects. The output end of the first motor 4 passes through the mixing box 3 and is connected to the rotating column 5. Multiple mixing blades 6 are installed on the outer surface of the rotating column 5 to turn the material over so that it comes into contact with the hot air sent in by the hot air blower 8, accelerating the evaporation of moisture and simultaneously mixing the raw materials. To ensure more uniform mixing and avoid localized accumulation, a humidity monitoring module 7 is installed on the inner top wall of the mixing tank 3. This module 7 uses a microwave radar sensor to detect the humidity of the raw materials inside the mixing tank 3 in real time. The data is transmitted to the controller 32 as a basis for judging whether the raw materials are properly dried, ensuring that the moisture content meets the standard. A hot air blower 8 is installed on the upper surface of the mixing tank 3 to introduce hot air into the mixing tank 3, providing the heat required for drying. By adjusting the hot air temperature and wind speed, the evaporation rate of the raw material moisture is controlled. The output end of the hot air blower 8 extends through the mixing tank 3 and into its interior. A valve 9 is installed on the bottom surface of the mixing tank 3. like Figure 1 As shown, a filter box 10 is installed on the upper surface of the mixing tank 3, which is a space for filtering and purifying raw materials. Inside, the filter plate 33 screens particles, intercepts impurities and oversized raw materials, and ensures that the particle size of the raw materials entering the mixing tank 3 meets the standards. A feed hopper 11 is installed on the upper surface of the filter box 10, which is the raw material inlet and guides the raw materials into the filter box 10. At the same time, it initially blocks large impurities or foreign objects, reducing the pressure of subsequent filtration.
[0019] like Figure 4 As shown, a second motor 12 is installed on the inner wall of the filter box 10 to drive the filter plate 33 to vibrate, improve filtration efficiency, break up slightly agglomerated raw materials, and allow qualified particles to pass through the filter plate 33 quickly. The output end of the second motor 12 is equipped with the filter plate 33.
[0020] like Figure 1 and Figure 2 As shown, a crushing box 13 is installed on the left side of the mixing box 3. A third motor 14 is installed on the outer surface of the crushing box 13. The output end of the third motor 14 passes through the crushing box 13 and is connected to a rotating rod 15, which provides power for crushing and drives the rotating rod 15 and the first gear 16 to rotate. The first gear 16 meshes with the rotating rod 15 and drives another crushing roller 19 to rotate synchronously in the opposite direction. The end of the rotating rod 15 away from the third motor 14 passes through the crushing box 13 and is connected to the first gear 16.
[0021] like Figure 4As shown, a round rod 17 is rotatably mounted on the inner wall of the crushing box 13. A second gear 18 is mounted on the outer surface of the round rod 17 and meshes with the first gear 16 to change the direction of power, so that the crushing roller 19 driven by the round rod 17 and the crushing roller 19 driven by the rotating rod 15 rotate in opposite directions to form a shearing force to crush the raw materials. The outer surface of the second gear 18 meshes with the outer surface of the first gear 16. Crushing rollers 19 are fixedly mounted on the outer surfaces of both the round rod 17 and the rotating rod 15.
[0022] like Figure 4 As shown, a first pump body 20 is installed on the upper surface of the crushing box 13 to pump the crushed raw materials in the crushing box 13 to the filter box 10. The output end of the first pump body 20 passes through the filter box 10 and extends into the interior of the filter box 10. The input end of the first pump body 20 is connected to a suction nozzle 21, and the outer surface of the suction nozzle 21 is connected to the outer surface of the crushing box 13.
[0023] like Figure 1 As shown, a second pump body 22 is installed on the upper surface of the base plate 1. It draws dry and qualified raw materials from the collection box 2 and transports them to the extruder body 24 through the transmission pipe 23, providing a stable material supply for the extrusion process. The input end of the second pump body 22 is connected to the outer surface of the collection box 2, and the output end of the second pump body 22 is connected to the transmission pipe 23. The end of the transmission pipe 23 away from the second pump body 22 is connected to the extruder body 24. A controller 32 is installed on the outer surface of the extruder body 24.
[0024] like Figure 2 As shown, a purification box 25 is installed on the right side of the extruder body 24. A support frame 26 is installed on the upper surface of the purification box 25. A guide roller 27 is rotatably installed on the inner wall of the support frame 26. A third pump body 28 is installed on the inner bottom wall of the purification box 25. The input end of the third pump body 28 passes through the purification box 25 and is connected to a suction block 29. The output end of the third pump body 28 is connected to an activated carbon filter block 30. Multiple air vents 31 are opened on the outer surface of the purification box 25.
[0025] The working principle of this utility model is as follows: First, the high-styrene rubber raw material enters the filter box 10 from the feed hopper 11. The second motor 12 is started by the controller 32 to drive the filter plate 33 to vibrate and perform preliminary filtration of large particles and impurities before falling into the crushing box 13. The third motor 14 is started by the controller 32 to drive the rotating rod 15 and the first gear 16 to rotate. Through gear meshing, the round rod 17 and the second gear 18 rotate in opposite directions, causing the two crushing rollers 19 to rotate in opposite directions, crushing the lumpy raw material into uniform particles. The crushed raw material particles are drawn back into the filter box 10 by the first pump body 20 for screening by the filter plate 33. The fine raw material particles screened out by the filter plate 33 enter the mixing box 3 through the feed port on the mixing box 3. After the material enters, the hot air blower 8 is started by the controller 32 to inject hot air into the box. At the same time, the second motor 14 drives the rotating rod 15 and the first gear 16 to rotate. The second motor 14 drives the rotating rod 15 and the first gear 16 to rotate. Through gear meshing, the round rod 17 and the second gear 18 rotate in opposite directions, causing the two crushing rollers 19 to rotate in opposite directions, crushing the lumpy raw material into uniform particles. The crushed raw material particles are then drawn back into the filter box 10 by the first pump body 20 for screening by the filter plate 33. The fine raw material particles screened out by the filter plate 33 enter the mixing box 3 through the feed port on the mixing box 3. After the material enters, the hot air blower 8 is started by the controller 32 to inject hot air into the box. A motor 4 drives a rotating column 5 and a stirring blade 6 to continuously agitate the raw materials, accelerating moisture evaporation. A humidity monitoring module 7 monitors the humidity inside the chamber in real time. When the preset value is reached, the controller 32 triggers the valve 9 to open, and the dried raw materials fall into the collection box 2. After the material is dried and enters the collection box 2, the controller 32 starts the second pump body 22 to transport the dried raw materials in the collection box 2 to the extruder body 24 through the transmission pipe 23. The internal structure of the extruder body 24 works together to heat and mix the material, and then extrudes it into the required shape through the die head. During the extrusion process, the waste gas generated is pumped to the purification box 25 by the controller 32 starting the third pump body 28 through the suction block 29. The waste gas first passes through the activated carbon filter block 30 to adsorb harmful substances, and then is discharged as qualified gas through the vent 31, reducing environmental pollution.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
