Description

Technical Field

[0001] This utility model belongs to the technical field of biomass fuel production equipment, specifically relating to a pressure roller structure for a biomass solid fuel molding machine. Background Technology

[0002] The processing of biomass solid fuel generally involves first crushing raw materials such as tea leaves, tea branches, twigs, sawdust, fruit shells, sugarcane bagasse, and corn cobs, then adding regulators and mixing them. The mixture is then formed using a pellet mill. Pelletizing typically involves extruding the mixed raw materials through a screen (forming plate / mesh) to form the pellet. During the forming process, the pressure rollers inevitably become contaminated with material, affecting subsequent forming operations and making cleaning difficult. Long-term adhesion can lead to material solidification and deterioration, impacting the forming effect and requiring significant time and labor for cleaning, which is detrimental to production. Therefore, a new pressure roller structure for biomass solid fuel pelletizing machines is needed to solve these technical problems. Summary of the Invention

[0003] To address the aforementioned deficiencies in existing technologies, this utility model provides a pressure roller structure for a biomass solid fuel molding machine. The pressure roller is located on a molding plate, which is covered with molding holes. Each pressure roller is connected to a motor, and at least two pressure rollers are provided. The motor is connected to a vertical rotating shaft, the upper end of which passes through the center of the molding plate and is connected to a connecting block. One end of each pressure roller is connected to the rotating shaft, and one end of the rotating shaft is connected to the connecting block. A scraper is positioned above the pressure roller, contacting it, and one end of the scraper is connected to the connecting block. The motor drives the connecting block to rotate, which in turn drives the pressure rollers to rotate on the molding plate. Material is pressed down by the pressure rollers and falls through the molding holes of the molding plate to form the material. Material adhering to the pressure rollers during the pressing process can be scraped off by the scraper, reducing adhesion.

[0004] Preferably, the connecting block has a transmission cavity, and a second motor is installed in the transmission cavity. A bevel gear is connected to the output shaft of the second motor. One end of the first rotating shaft is fixedly connected to the pressure roller, and the other end of the first rotating shaft extends into the transmission cavity and is connected to the second bevel gear. The second bevel gear meshes with the first bevel gear. The first rotating shaft is rotatably connected to the connecting block through a bearing. The second motor drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear to rotate, thereby causing the pressure roller to rotate. The rotation of the pressure roller not only facilitates the scraper to scrape the material and avoids material sticking to the pressure roller, but also allows the pressure roller to roll autonomously, reducing the resistance of the pressure roller rotating with the vertical rotating shaft and improving the forming effect.

[0005] A bevel gear three is fixedly connected to the lower end of the vertical rotating shaft. The bevel gear three meshes with a bevel gear four, which is connected to a motor. A wire channel is provided inside the vertical rotating shaft. A wire is connected to the motor, and one end of the wire passes through the wire channel and is connected to an external power source via a conductive slip ring. This arrangement allows the pressure roller to rotate simultaneously with the active rotation and rotation of the vertical rotating shaft without interference.

[0006] Preferably, the forming plate is fixed inside the forming box, and a slider is rotatably connected to the center of the end of the pressure roller away from the connecting block via a bearing. A groove is provided on the inner wall of the forming box corresponding to the slider, and the slider is slidably disposed in the groove. This arrangement improves the stability of the pressure roller when it rotates with the vertical shaft.

[0007] Preferably, the forming plate is fixed inside the forming box, and the center of the end of the pressure roller away from the connecting block is rotatably connected to a second rotating shaft via a bearing. The other end of the second rotating shaft is connected to a connecting ring, which is rotatably connected to the inner wall of the corresponding forming box via a bearing. The connection ring improves the stability of each pressure roller, allowing both the rotation and revolution of the pressure roller to proceed effectively.

[0008] Preferably, the bottom of the forming box is connected to a receiving box, and a cutting blade is fixed on the vertical rotating shaft below the forming plate. The cutting blade cuts the material falling from the forming hole into shape. The bottom of the receiving box is an inclined plate, and a discharge pipe is provided on the side wall of the receiving box corresponding to the lower end of the inclined plate.

[0009] Preferably, the top of the connecting block is conical to reduce material buildup at the top of the connecting block.

[0010] Working principle: Material enters the forming box and falls onto the forming plate. Motor 1 drives the pressure roller to rotate, and the material falls through the forming holes of the forming plate under the crushing action of the pressure roller. During the pressing process, any material adhering to the pressure roller can be scraped off by the scraper, reducing adhesion. In the above process, Motor 2 drives Bevel Gear 1 to rotate, which in turn drives Bevel Gear 2, thus causing the pressure roller to rotate. The rotation of the pressure roller not only facilitates the scraper to scrape the material evenly, preventing material from sticking to the pressure roller, but also reduces the resistance of the pressure roller rotating with the vertical shaft, improving the forming effect.

[0011] This utility model also includes other components that enable the normal operation of the pressure roller structure of a biomass solid fuel molding machine, such as the control components for motor one and motor two, which are all conventional technologies in the field. Furthermore, devices or components not specified in this utility model, such as pressure rollers, scrapers, cutting blades, forming holes, conductive slip rings, and wires, all employ conventional technologies and equipment in the field.

[0012] The beneficial effects of this utility model are: the structure is simple and reasonable, and it can perform scraping operation on the pressure roller, reducing material adhesion and reducing adverse effects on the next molding operation. Attached Figure Description

[0016] The present invention will now be clearly described with reference to the accompanying drawings and specific embodiments. This description is merely for explaining the present invention and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art based on the embodiments of the present invention without inventive effort to obtain all other embodiments should be included within the protection scope of the present invention.

[0017] Example 1 like Figure 1As shown, this utility model provides a structure for a biomass solid fuel molding machine pressure roller 3, including a pressure roller 3 located on a molding plate 8. The molding plate 8 is covered with molding holes 7. A motor 9 is connected to each pressure roller 3. At least two pressure rollers 3 are provided. The motor 9 is connected to a vertical rotating shaft. The upper end of the vertical rotating shaft passes through the center of the molding plate 8 and is connected to a connecting block 5. One end of each pressure roller 3 is connected to the rotating shaft 9, and one end of the rotating shaft 9 is connected to the connecting block 5. A scraper 4 is provided above each pressure roller 3, contacting the pressure roller 3. One end of the scraper 4 is connected to the connecting block 5. The motor drives the connecting block 5 to rotate, which in turn drives each pressure roller 3 to rotate on the molding plate 8. Under the crushing action of the pressure roller 3, the material falls from the molding holes 7 of the molding plate 8 and is formed. During the pressing process, any material adhering to the pressure roller 3 can be scraped off by the scraper 4, reducing adhesion.

[0018] The bottom of the forming box 1 is connected to the receiving box 2. A cutting blade 6 is fixed on the vertical rotating shaft below the forming plate 8. The cutting blade 6 cuts the material falling from the forming hole 7 into shape. The bottom of the receiving box 2 is an inclined plate 10. A discharge pipe 11 is provided on the side wall of the receiving box 2 corresponding to the lower end of the inclined plate 10.

[0019] The top of the connecting block 5 is conical, which reduces the amount of material piled up at the top of the connecting block 5.

[0020] Example 2 like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the connecting block 5 has a transmission cavity 13, and the transmission cavity 13 has a second motor 15. The output shaft of the second motor 15 is connected to a bevel gear 12. One end of the first rotating shaft is fixedly connected to the pressure roller 3, and the other end of the first rotating shaft extends into the transmission cavity 13 and is connected to a second bevel gear 14. The second bevel gear 14 meshes with the first bevel gear 12. The first rotating shaft is rotatably connected to the connecting block 5 through a bearing. The second motor 15 drives the first bevel gear 12 to rotate, and the first bevel gear 12 drives the second bevel gear 14 to rotate, thereby causing the pressure roller 3 to rotate. The rotation of the pressure roller 3 not only facilitates the scraper 4 to scrape the material, preventing material from sticking to the pressure roller 3, but also allows the pressure roller 3 to roll independently, reducing the resistance of the pressure roller 3 rotating with the vertical rotating shaft. This improves the molding effect.

[0021] A bevel gear 16 is fixedly connected to the lower end of the vertical rotating shaft. The bevel gear 16 meshes with a bevel gear 17, which is connected to a motor 9. A wire channel is provided inside the vertical rotating shaft, and a wire is connected to the motor 15. One end of the wire passes through the wire channel and is connected to an external power source via a conductive slip ring 18. This arrangement allows the pressure roller 3 to rotate simultaneously with the active rotation and rotation of the vertical rotating shaft without interference.

[0022] Example 3 like Figure 3 As shown, the difference between this embodiment and Embodiment 2 is that the forming plate 8 is fixed inside the forming box 1, and the center of the end of the pressure roller 3 away from the connecting block 5 is rotatably connected to a slider 19 via a bearing. A groove is provided on the inner wall of the forming box 1 corresponding to the slider 19, and the slider 19 is slidably disposed within the groove. This arrangement improves the stability of the pressure roller 3 when rotating with the vertical shaft.

[0023] Example 4 like Figure 4-5 As shown, the difference between this embodiment and Embodiment 2 is that four pressure rollers are provided. The forming plate 8 is fixed inside the forming box 1. The center of the end of the pressure roller 3 away from the connecting block 5 is rotatably connected to a second rotating shaft 20 via a bearing. The other end of the second rotating shaft 20 is connected to a connecting ring 21. The connecting ring 21 is rotatably connected to the inner wall of the corresponding forming box 1 via a bearing. The setting of the connecting ring 21 improves the stability of each pressure roller 3, so that the rotation and revolution of the pressure roller 3 can be carried out effectively.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
