Mixing equipment for producing and processing epdm rubber

Abstract

This utility model relates to an internal mixing equipment for EPDM rubber production and processing. The structure includes: a main body of the internal mixer, an assembly base, a feeding pipe, a guide pipe, a U-shaped pipe, a first auger rod, and a second auger rod. An assembly base is located on one side of the main body of the internal mixer, and a feeding pipe is fixedly connected to the upper surface of the assembly base. By installing the feeding pipe, guide pipe, U-shaped pipe, first auger rod, and second auger rod, rubber raw material is first poured into the inlet of the feeding pipe. The rubber raw material enters the feeding pipe, and the first auger rod inside the feeding pipe rotates, conveying the rubber raw material upwards. The rubber raw material then enters the guide pipe through the U-shaped pipe. The second auger rod inside the guide pipe rotates, controlling the rubber raw material to enter the feed hopper of the main body of the internal mixer. This facilitates the automatic feeding of rubber raw material into the main body of the internal mixer, reducing the pressure of manual feeding and improving the convenience of the internal mixer.

Description

Technical Field

[0001] This utility model relates to the field of closed plastic mixing machine technology, and in particular to a mixing equipment for EPDM rubber production and processing. Background Technology

[0002] The closed-type plasticizer is a key piece of equipment in the production and processing of EPDM rubber. It adopts a fully enclosed structure and uses a high-speed rotating rotor to subject the rubber to strong shearing, extrusion and friction to achieve efficient plasticization. In the processing of EPDM rubber, this equipment can precisely control the temperature and mixing time to ensure that the rubber molecular chains break evenly, improve plasticity, and avoid the oxidation and pollution problems in open processing. Its closed characteristics can also effectively reduce dust emission and ensure a clean production environment. It is an important process equipment for preparing high-quality EPDM rubber products (such as sealing strips and tire sidewall rubber).

[0003] When using a closed plasticizer for rubber processing, workers need to manually move large or granular rubber raw materials to the equipment's feed inlet and gradually pour them out to complete the feeding. Since the equipment is usually not equipped with an automatic feeding structure, manual operation requires frequent bending over and moving heavy objects, which is labor-intensive and inefficient. In addition, manual operation also poses risks such as raw material spillage and dust pollution, which not only affect the on-site environment but also increase cleaning costs, significantly weakening the convenience advantage of the closed plasticizer in automated production.

[0004] Therefore, in response to the above problems, a new internal mixing equipment for EPDM rubber production and processing is proposed. Utility Model Content

[0005] To overcome the problems existing in related technologies, this utility model provides a mixing equipment for EPDM rubber production and processing, which can be designed with an automatic feeding structure on one side of the closed plasticizer to convey the rubber raw material upward through an auger, and then cooperate with another auger to horizontally feed the rubber raw material into the feed hopper of the closed plasticizer.

[0006] To achieve the above objectives, the first aspect of this utility model provides a mixing apparatus for EPDM rubber production and processing, comprising: The main body of the internal mixer, the assembly base, the feeding pipe, the guide pipe, the U-shaped pipe, the first auger rod, and the second auger rod; The main body of the internal mixer is provided with an assembly base on one side. A feeding pipe is fixedly connected to the upper surface of the assembly base. A guide pipe is fixedly connected to the upper surface of the assembly base on one side of the feeding pipe. A U-shaped tube is bolted to the top of the feeding pipe and the top of the guide pipe. A first auger rod is rotatably connected inside the feeding pipe, and a second auger rod is rotatably connected inside the guide pipe.

[0007] Furthermore, a first transmission rod is rotatably connected to the feeding pipe. The top end of the first transmission rod is connected to one side of the second auger rod via a bevel gear. Below the first auger rod, a second transmission rod is rotatably connected to the mounting base. One side of the second transmission rod is connected to the bottom end of the first auger rod via a bevel gear, and the other side of the second transmission rod is connected to the bottom end of the first transmission rod via a bevel gear.

[0008] Furthermore, a servo motor located below the first transmission rod is fixedly connected to the upper surface of the mounting base, and the output shaft of the servo motor is fixedly connected to the second transmission rod.

[0009] Furthermore, an observation port is provided on the U-shaped tube.

[0010] Furthermore, pneumatic hammers are bolted to both the upper surface of the feed tube and the upper surface of the U-shaped tube.

[0011] Furthermore, a first positioning seat is symmetrically and fixedly connected to the top end of the feeding pipe, a second positioning seat is symmetrically and fixedly connected to the top end of the guiding pipe, and positioning posts are symmetrically and fixedly connected to both ends of the U-shaped pipe. Both the first positioning seat and the second positioning seat are slidably connected to the positioning posts.

[0012] Furthermore, the feed inlet of the feed pipe adopts an inclined design.

[0013] The technical solution provided by this utility model can include the following beneficial effects: In this example, by installing a feeding pipe, a guide pipe, a U-shaped pipe, a first auger rod, and a second auger rod, the rubber raw material is first poured into the inlet of the feeding pipe. The rubber raw material enters the inside of the feeding pipe, and the first auger rod inside the feeding pipe rotates to convey the rubber raw material upwards. The rubber raw material enters the inside of the guide pipe through the U-shaped pipe, and the second auger rod inside the guide pipe rotates to control the rubber raw material to enter the feed bin of the internal mixer body. This facilitates the automatic feeding of rubber raw material into the internal mixer body, reduces the pressure of manual feeding, and improves the convenience of the internal mixer body.
