Description

Technical Field

[0001] This utility model belongs to the field of chipper flying knife, specifically a self-lubricating chipper flying knife. Background Technology

[0002] In the wood processing and similar industries, chippers are a crucial piece of equipment used to cut wood or other fibrous materials into thin slices for subsequent processing. The flying blades in the chipper, as key components that directly participate in the cutting process, have a performance that directly affects cutting efficiency and slice quality.

[0003] During use, the flying knife is installed in the slots opened on the cutter head. When wood needs to be cut, the power mechanism of the chipper first transmits power to the cutter head, which drives the flying knife to rotate at high speed. The high-speed rotating flying knife then contacts the wood to chip it. However, during the high-speed cutting process, the friction between the flying knife and the wood generates a lot of heat and wear, which not only accelerates the wear of the flying knife but also reduces its service life.

[0004] In summary, this utility model provides a self-lubricating chipper blade to solve the above problems. Utility Model Content

Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0020] Example 1

[0021] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a self-lubricating chipper blade, including a lubrication component 1. The lubrication component 1 includes a connecting frame 11. The inner cavity of the connecting frame 11 is provided with a solid lubricant, and a slot 12 is provided on the left side of the connecting frame 11. The inner cavity of the slot 12 is movably connected to a blade body 2. Fixing components 3 are provided on both the front and back of the connecting frame 11. A flow guide 13 is fixedly connected to the upper and lower ends of the left side of the connecting frame 11, and the flow guide 13 is connected to the connecting frame 11. Microholes 14 are provided on the side of the two flow guides 13 near the slot 12.

[0022] like Figure 1-4 As shown, by placing the blade body 2 in the inner cavity of the slot 12 and rotating the bolt 32, the bolt 32 will pass through the connecting plate 31 and gradually enter the inner cavity of the positioning hole 21, thereby firmly fixing the blade body 2 on the connecting frame 11, ensuring the stability and accuracy of the blade body 2 in the later cutting process. During the high-speed rotation of the blade body 2 to cut the wood, the solid lubricant in the inner cavity of the connecting frame 11 will be transferred to the inner cavity of the guide frame 13 under the action of centrifugal force, and will be thrown out through the micro-holes 14 on the guide frame 13. In this way, the solid lubricant will be coated on the surface of the blade body 2, thus forming a continuous lubricating film during the cutting process, thereby effectively reducing friction and wear.

[0023] Example 2

[0024] Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0025] In this embodiment, the top of the connecting frame 11 is connected to a filling port 111, the top of the filling port 111 is movably connected to a round cover, the right side of the connecting frame 11 is fixedly connected to a mounting plate 112, and the top of the mounting plate 112 is provided with a mounting groove.

[0026] A rubber buffer pad 121 is fixedly connected to the inner wall of the slot 12, and the blade body 2 is located in the inner cavity of the slot 12 and is in contact with the rubber buffer pad 121.

[0027] like Figure 1-4As shown, by simply opening and closing the round cover, users can easily replenish the lubricant for the lubrication assembly 1. The operation is simple and quick. The design of the round cover ensures the sealing of the lubrication assembly 1 and guarantees the continuous and effective use of the lubricant. With the mounting plate 112 and the mounting groove, it is easy to install the lubrication assembly 1 and the cutting tool body 2 in the cutting groove opened on the cutting head. The rubber buffer pad 121 can absorb some of the vibration and impact during the cutting process, which plays a buffering and protection role for the cutting tool body 2 and further extends the service life of the cutting tool body 2.

[0028] Example 3

[0029] Reference Figure 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0030] In this embodiment, the fixing component 3 includes a connecting plate 31, and the side of the connecting plate 31 closest to the connecting frame 11 is fixedly connected to the connecting frame 11. A bolt 32 is provided on the side of the connecting plate 31 away from the connecting frame 11. The bolt 32 passes through the inner cavity of the connecting plate 31 and is threadedly connected to the inner cavity of the connecting plate 31.

[0031] Positioning holes 21 are provided on both the front and back sides of the blade body 2. One end of the bolt 32 extends into the inner cavity of the positioning hole 21 and is movably connected to the inner cavity of the positioning hole 21.

[0032] like Figure 4 As shown, the blade body 2 is initially positioned by placing it in the inner cavity of the slot 12. The blade body 2 can slide in the inner cavity of the slot 12 according to the cutting requirements of the wood, thereby adjusting the length of the blade body 2 entering the slot 12. This facilitates the adjustment of the length of the blade body 2 extending out. After adjustment, the bolt 32 can be rotated. Since the bolt 32 and the connecting plate 31 are threaded, the bolt 32 will pass through the connecting plate 31 and gradually enter the inner cavity of the positioning hole 21. This will firmly fix the adjusted blade body 2 on the connecting frame 11, ensuring the stability and accuracy of the blade body 2 in the later cutting process.

[0033] In use, first place the blade body 2 inside the slot 12 to achieve initial connection. The length of the blade body 2 inside the slot 12 can be adjusted according to the cutting requirements of the wood. After adjustment, by rotating the bolt 32, since the bolt 32 and the connecting plate 31 are threaded, the bolt 32 will pass through the connecting plate 31 and gradually enter the inner cavity of the positioning hole 21, thus firmly fixing the blade body 2 to the connecting frame 11, ensuring the stability and accuracy of the blade body 2 in the later cutting process. When the chipper starts working, the power mechanism of the chipper will drive the cutter head to rotate, at which time the blade body... 2. The blade body 2 rotates at high speed with the cutter head. During the high-speed rotation of the blade body 2 to cut the wood, the solid lubricant in the inner cavity of the connecting frame 11 is transferred to the inner cavity of the guide frame 13 under the action of centrifugal force, and is thrown out through the micro-holes 14 on the guide frame 13. In this way, the solid lubricant will be coated on the surface of the blade body 2. Thus, a continuous lubricating film is formed during the cutting process, which effectively reduces friction and wear. When it is necessary to replenish the solid lubricant, the user only needs to open the round cover on the filling port 111 and inject the new lubricant into the inner cavity of the connecting frame 11. The whole process is simple and quick, improving the convenience of use.
