Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to a twin-screw extruder for processing compound rubber. Background Technology

[0002] Twin-screw extruders are high-quality and efficient plastic extrusion equipment. The extruder has a reasonable overall structure design, is sturdy and durable, and is not easily damaged. Twin-screw extruders are required for processing compounded rubber.

[0003] For example, patent (CN211868574U) discloses a micro twin-screw extruder, including a device body. A feed port is fixedly connected to the upper end of the outer wall of the device body. A first gear and a second gear are arranged on the right side of the device body. The first gear and the second gear are meshed and connected. A rotating shaft is connected through the center of both the first gear and the second gear. A rotary motor is installed at the right end of the lower rotating shaft. A mounting block is installed at the left end of both rotating shafts. A screw is fixedly connected to the left side of both mounting blocks. Industrial heating pads are movably connected to the front and rear sides of the outer wall of the device body. The material is put into the device body through the feed port. The rotary motor is started to make the first gear drive the second gear to rotate, which in turn drives the two screws to rotate, pushing the material to the left side of the device body. The industrial heating pad heats and melts the material and extrudes it into the mold. After the experiment is completed, the mounting blocks and the rotating shaft are disassembled and the inside of the device body is cleaned.

[0004] When using the above technology, the following technical problems were found in the existing technology: the existing technology does not have the effect of crushing materials, which makes it easy for larger particles to clog the feed port, thus seriously affecting the normal operation of the extruder. At the same time, larger materials reduce the extrusion effect of the extruder, and feeding different particles into the feeding hopper for processing and extrusion makes it difficult to mix different particles, thus reducing the quality and effect of extrusion. To address these issues, we designed a twin-screw compound rubber processing extruder to provide an alternative technical solution. Utility Model Content

[0005] Based on this, it is necessary to provide a twin-screw compound rubber processing extruder to address the aforementioned technical problems. The compound rubber raw material is fed into the hopper, then crushed and mixed before flowing into the extruder body. A servo motor is then activated, driving the driven gears to rotate. This, in turn, causes the transmission gears to rotate the two driven gears, which in turn drive the two screw processing components to rotate in opposite directions. This process heats and melts the crushed and mixed compound rubber raw material before the screw processing components discharge it.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A twin-screw rubber compound processing extruder includes an extruder body, with support blocks fixed at both ends of the bottom of the extruder body. A discharge port is located at the left end of the interior of the extruder body, and a feed hopper is fixed at the right end of the top of the extruder body. Screw processing assemblies are rotatably connected to both sides of the interior of the extruder body. A driven gear is fixed to the right end of the screw processing assembly, passing through the extruder body. A U-shaped block is fixed to the right end of the extruder body, and a servo motor is mounted on the right end of the U-shaped block. A transmission gear is fixed to the output end of the servo motor, and the two sides of the transmission gear mesh with the driven gear.

[0008] In a preferred embodiment of the twin-screw compound rubber processing extruder provided by this utility model, the inside of the feed hopper is provided with a crushing mechanism and a stirring mechanism, and a guide bucket is fixed inside the feed hopper.

[0009] In a preferred embodiment of the twin-screw compound rubber processing extruder provided by this utility model, a triangular support frame is fixed at the top of the inside of the feed hopper, a transmission rod is rotatably connected inside the triangular support frame, and a crushing blade is fixed on the outside of the transmission rod and above the guide hopper.

[0010] In a preferred embodiment of the twin-screw compound rubber processing extruder provided by this utility model, an agitator is fixed on the outer side of the transmission rod and below the guide hopper, and the outer side of the agitator is rotatably connected to the feed hopper.

[0011] In a preferred embodiment of the twin-screw compound rubber processing extruder provided by this utility model, a second servo motor is fixed at the top of the triangular support frame, and the output end of the second servo motor passes through the triangular support frame and is fixed to the transmission rod.

[0012] In a preferred embodiment of the twin-screw compound rubber processing extruder provided by this utility model, the two driven gears and screw processing components rotate in opposite directions.

[0013] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0014] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0015] This utility model provides a twin-screw extruder for processing rubber compound. The rubber compound is fed into the hopper, and then a servo motor is started to drive the transmission rod to rotate. The transmission rod drives the crushing blade and the stirring blade to rotate synchronously. The crushing blade effectively crushes large particles of rubber compound to improve the heating and melting effect of the rubber compound. The stirring blade effectively mixes different rubber compound materials, promoting the extrusion efficiency and quality of the device. Attached Figure Description

A driven gear 7 is fixed through the extruder body 1 at the right end of the screw processing component 5. The two driven gears 7 and the screw processing component 5 rotate in opposite directions. A U-shaped block 6 is fixed at the right end of the extruder body 1, and a servo motor 8 is assembled at the right end of the U-shaped block 6. A transmission gear 9 is fixed at the output end of the servo motor 8, and the two sides of the transmission gear 9 are meshed with the driven gear 7.

[0028] Specifically, the rubber compound is fed into the feed hopper 2, and after being crushed and mixed, it flows into the extruder body 1. Then, the servo motor 8 is started to drive the passive gear 7 to rotate, which in turn drives the two passive gears 7 to rotate. The passive gears 7 drive the two screw processing components 5 to rotate in opposite directions, so as to heat and melt the crushed and mixed rubber compound. Then, the screw processing components 5 discharge the mixture.

[0029] The feed hopper 2 is equipped with a crushing mechanism and a stirring mechanism. A guide hopper 14 is fixed inside the feed hopper 2. A triangular support frame 11 is fixed at the top inside the feed hopper 2. A transmission rod 13 is rotatably connected inside the triangular support frame 11.

The transmission rod 13 drives the crushing blade 12 and the stirring blade 15 to rotate synchronously. The crushing blade 12 effectively crushes the large particles of the rubber compound, so as to improve the heating and melting effect of the rubber compound and promote the extrusion efficiency and quality of the device.

[0031] When different rubber compound raw materials are fed into the inside of the feed hopper 2, the crushing blade 12 crushes them, while the stirring blade 15 effectively mixes the different rubber compound raw materials, thereby improving the practicality of the extruder.

[0032] The following is the usage process of the twin-screw compound rubber processing extruder provided by this utility model: During use, the compound rubber raw material is put into the feed hopper 2, and then the servo motor 10 is started to drive the transmission rod 13 and the stirring blade 15 to crush and stir, so as to improve the heating and melting effect of the compound rubber raw material. The crushed and stirred compound rubber raw material flows into the extruder body 1, and then the servo motor 8 is started to drive the driven gear 7 to rotate, so that the transmission gear 9 drives the two driven gears 7 to rotate, and the driven gears 7 drive the two screw processing components 5 to rotate in opposite directions, so as to heat and melt the crushed and stirred compound rubber raw material, and then the screw processing components 5 discharge.
