Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a grinding device for oak bark. Background Technology

[0002] Oak belongs to the family Fagaceae and the genus Quercus. There are two types: red oak (Quercus variabilis) and white oak (Quercus serrata). The outer bark is dark brown, slightly rough, with shallow longitudinal cracks, and easily peels off in small pieces. The inner bark is yellowish-white, and the bast fibers are well-developed. Due to its excellent material properties, oak is widely used in many fields such as furniture, flooring, sliced ​​veneer, decorative veneer, and vehicle and ship manufacturing.

[0003] Oak pellets are granular materials made from oak wood chips and bark. As one of the raw materials for particleboard, they are used in the production of furniture and decoration materials. They can also be used to produce cork products such as cork stoppers, cork rubber, and cork flooring. Before pellet production, the raw materials need to be crushed to meet the requirements of pellet production. When the grinder is used to process the raw materials, a filter screen is used to control the particle size. During processing, particles will inevitably clog the mesh of the filter screen, which can easily affect the screening effect and feeding efficiency.

[0004] Therefore, we propose a grinding device for oak bark to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figures 1-4 As shown, an embodiment of this utility model discloses a grinding device for oak bark, comprising a frame 1, a hopper 2 installed at the bottom of the table of the frame 1, a body 3 installed at the top of the table of the frame 1, and a grinding roller 4 installed inside the body 3. A motor 5 is installed on the table of the frame 1, and the output shaft of the motor 5 is connected to the shaft end of the grinding roller 4. An assembly port 6 is provided in the lower inner part of the body 3, and a return spring 7 is installed at the assembly port 6. A screen 8 is installed on the return spring 7, and foam strips 9 are used to fill the joint between the screen 8 and the assembly port 6. A servo motor 10 is installed on the outer side of the body 3. The output shaft of the servo motor 10 is connected to a shaft 11, on which a cam 12 is mounted. The screen 8 is mounted at the assembly port 6 via a return spring 7. The servo motor 10 drives the cam 12 on the shaft 11 to rotate, causing the tip of the cam 12 to continuously press against the bottom surface of the screen 8, which causes the screen 8 to vibrate continuously up and down. This vibration can effectively prevent oak bark particles from clogging the mesh of the screen 8, ensuring that particles that meet the particle size requirements can pass through smoothly, improving the screening effect and feeding efficiency. At the same time, the joint between the screen 8 and the assembly port 6 is filled with foam strips 9, which enhances the sealing of the joint and prevents unscreened particles from leaking out from the gap.

[0028] like Figure 3 As shown, in some embodiments, the hopper 2 is positioned corresponding to the body 3, and the bottoms of the hopper 2 and the body 3 are interconnected. The interconnection between the hopper 2 and the bottoms of the body 3 facilitates the collection of the screened particles, and the overall design meets the actual needs of oak bark grinding and processing.

[0029] like Figure 3 As shown, in some embodiments, the top of the machine body 3 is provided with a feeding hopper 13, and the top of the feeding hopper 13 is hinged to a flip cover 14. The feeding hopper 13 is for convenient addition of oak bark raw materials, and the flip cover 14 can prevent dust from escaping during the grinding process and improve the working environment.

[0030] like Figure 3As shown, in some embodiments, the machine body 3 is a cylindrical structure, and an impact plate 15 is installed on the inner wall of the machine body 3. The grinding roller 4 rotates under the drive of the motor 5 and cooperates with the impact plate 15 to grind the oak bark. This structural design allows the raw material to be fully subjected to grinding and impact within the machine body 3, improving grinding efficiency and grinding quality, and making the raw material particles more uniform.

[0031] like Figure 1 As shown, in some embodiments, the two shaft ends of the grinding roller 4 are mounted in the machine body 3 by bearings, and one shaft end of the grinding roller 4 is connected to the output shaft end of the motor 5 by a coupling. The grinding roller 4 is mounted by bearings to ensure stable rotation. Under the drive of the motor 5, it rotates and cooperates with the impact plate 15 to grind the oak bark.

[0032] like Figure 3 As shown, in some embodiments, the return spring 7 is located around the screen 8, which is arc-shaped. The core function of the return spring 7 is to provide a restoring force to ensure that the mechanical parts quickly and accurately return to their original position after the external force disappears.

[0033] like Figure 1 As shown, in some embodiments, the shaft 11 is mounted inside the machine body 3 by bearings, and the shaft 11 is located directly below the screen 8. The shaft 11 is mounted by bearings and located directly below the screen 8 to ensure that the vibration of the cam 12 on the screen 8 is uniform and effective.

[0034] like Figure 3 As shown, in some embodiments, the cams 12 are evenly distributed on the shaft 11, and the tip of the cam 12 is in contact with the bottom surface of the screen 8. The servo motor 10 drives the cams 12 on the shaft 11 to rotate, so that the tip of the cam 12 continuously contacts the bottom surface of the screen 8, which can cause the screen 8 to vibrate continuously up and down.

[0035] During use, oak bark is added through the feeding hopper 13. The hinged flap 14 prevents dust from escaping during grinding. The grinding roller 4 rotates under the drive of the motor 5, cooperating with the impact plate 15 to grind the oak bark. This structural design allows the raw material to be fully ground and impacted within the machine body 3, improving grinding efficiency and quality, and making the raw material particles more uniform. The screen 8 is installed at the assembly port 6 via a return spring 7. The servo motor 10 drives the cam 12 on the shaft 11 to rotate, causing the tip of the cam 12 to continuously abut against... The bottom surface of the screen 8 allows it to vibrate continuously up and down. This vibration effectively prevents oak bark particles from clogging the mesh of the screen 8, ensuring that particles that meet the particle size requirements can pass through smoothly, improving the screening effect and feeding efficiency. At the same time, the joint between the screen 8 and the assembly port 6 is filled with foam strips 9 (a flexible sealing material made of EVA or PE foam, which has good resilience and compressibility and can quickly return to its original shape after being compressed, thereby achieving functions such as sealing and shock absorption), which enhances the sealing of the joint and prevents unscreened particles from leaking out from the gaps.

[0036] In summary, the screen 8 is installed at the assembly port 6 via a return spring 7. The servo motor 10 drives the cam 12 on the shaft 11 to rotate, causing the tip of the cam 12 to continuously press against the bottom surface of the screen 8, resulting in continuous up-and-down vibration of the screen 8. This vibration effectively prevents oak bark particles from clogging the mesh of the screen 8, ensuring that particles meeting the particle size requirements pass through smoothly, thus improving the screening effect and feeding efficiency. At the same time, the joint between the screen 8 and the assembly port 6 is filled with foam strips 9, which enhances the sealing of the connection and prevents unscreened particles from leaking out from the gaps.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
