Description

Technical Field

[0001] This utility model relates to a ring-shaped molding machine for biomass pellets, belonging to the field of biomass manufacturing technology. Background Technology

[0002] Biomass fuel is a new type of clean fuel made from agricultural and forestry waste as raw materials. Through processes such as crushing, mixing, extrusion, and drying, it is made into various shapes that can be directly burned. As people pay more and more attention to environmental pollution, how to properly handle crop straw has become one of the current research focuses in my country. The emergence of biomass densification molding technology can provide a high-efficiency way to reuse straw resources. Biomass molding equipment includes ring molding machines, spiral extrusion molding machines, and piston stamping molding machines.

[0003] The ring die forming machine consists of two key parts: a ring die and a pressure roller. The pressure roller rotates around its own axis and has teeth machined on its outer surface, which facilitates the pressing of materials and prevents slippage. The ring die has a certain number of forming holes inside. When biomass material enters between the pressure roller and the ring die, the relative movement between the two causes the biomass material to be continuously pressed into the forming holes of the ring die and extruded. A cutting device is installed at the discharge port, which cuts the biomass fuel into pellets of a certain length.

[0004] Since the pressure roller is inserted into the working cavity of the ring die during operation, it must be removed from the working cavity for maintenance and replacement. Traditionally, the pressure roller is mounted on the intermediate seat through the pressure roller drive component. During maintenance and replacement, a forklift or crane must be used to remove the intermediate seat and then disassemble and replace the pressure roller. This replacement and maintenance method is extremely inefficient and requires a lot of manpower. Therefore, we provide a ring die forming machine for biomass pellets to solve the above problems.

[0021] Please see Figure 1-4In this utility model, a ring-shaped forming machine for biomass pellets includes a frame 6 and a movable plate 3. A pressure roller mechanism 9 is fixedly installed on the bottom surface of the movable plate 3, and a drive block 8 is fixedly installed on the bottom surface of the movable plate 3. A threaded hole 12 is opened on one side of the drive block 8. A strip groove 5 is opened on the upper surface of the frame 6. Two first bearings 11 are fixedly embedded in the inner wall of the strip groove 5. A threaded rod 10 is fixedly installed on the inner ring of the two first bearings 11. The outer surface of the threaded rod 10 is threadedly connected to the inner wall of the threaded hole 12. A base 1 is installed on one side of the frame 6. The two ends of the threaded rod 10 are respectively connected to the inner rings of the two first bearings 11. The threaded rod 10 is fixedly installed, allowing it to rotate freely. By connecting the outer surface of the threaded rod 10 to the inner wall of the threaded hole 12 on one side of the drive block 8, the rotation of the threaded rod 10 can drive the drive block 8 to move. The movement of the drive block 8 can then drive the moving plate 3 and the pressure roller mechanism 9 mounted on the moving plate 3 to move. A servo motor 2 is mounted on the upper surface of the base 1. The output end of the servo motor 2 is fixedly installed to one end of the threaded rod 10 via a coupling. By using a coupling to fix the output end of the servo motor 2 to one end of the threaded rod 10, the servo motor 2 can provide rotational power for the rotation of the threaded rod 10.

[0022] Two L-shaped slide rails 4 are provided on the upper surface of the frame 6, and two L-shaped sliders 13 are installed on the bottom surface of the moving plate 3. The outer surface of each L-shaped slider 13 is slidably connected to the inner wall of the L-shaped slide rail 4. Through the cooperation of the two L-shaped sliders 13 and the two L-shaped slide rails 4, the moving plate 3 can maintain stability when driving the pressure roller mechanism 9. The two L-shaped sliders 13 and the two L-shaped slide rails 4 together play a limiting role for the moving plate 3. A ring die mechanism 7 is fixedly installed on the upper surface of the frame 6. The ring die mechanism 7 includes a ring die body 701 and a ring die drive component 702. The ring die body 701 is connected to the drive end of the ring die drive component 702.

[0023] The pressure roller mechanism 9 includes a fixed block 902 and a support plate 904. A second bearing 905 is fixedly embedded on one side of the fixed block 902. A rotating shaft 906 is fixedly installed on the inner ring of the second bearing 905. A pressure roller body 901 is installed on one end of the rotating shaft 906. A drive motor 903 is fixedly installed on the upper surface of the support plate 904. The output end of the drive motor 903 is fixedly installed on one end of the rotating shaft 906. By fixing the output end of the drive motor 903 to one end of the rotating shaft 906, the drive motor 903 can provide rotational power for the rotating shaft 906. By fixing one side of the pressure roller body 901 to one end of the rotating shaft 906, the rotating shaft 906 can drive the pressure roller body 901 to rotate.

[0024] The working principle of this utility model is as follows:

[0025] When the pressure roller body 901 needs to be replaced, the operator first controls the output end of the servo motor 2 to rotate. The rotation of the output end of the servo motor 2 will drive the threaded rod 10 to rotate through the coupling. The threaded rod 10 cooperates with the threaded hole 12 on one side of the drive block 8. The rotation of the threaded rod 10 will drive the drive block 8 to move. Through the cooperation of the two L-shaped sliders 13 and the two L-shaped slide rails 4, the movement of the drive block 8 will drive the moving plate 3 and the pressure roller mechanism 9 to move smoothly. When one end of the pressure roller mechanism 9 is completely removed from the inside of the ring mold mechanism 7, the operator can replace the pressure roller body 901.
