[0002] Wood is an indispensable resource in industry or life. When processing logs, it is necessary to cut them. Therefore, cutting equipment is needed in the process. When cutting logs, existing cutting equipment usually needs to use a cutting disc that matches the diameter of the log. If the log has a large diameter, the operator needs to use a larger cutting disc to cut it, or the operator rotates the log to cut it, which also requires a larger cutting disc. The larger cutting disc is easy to break during the cutting process, thereby reducing the cutting effect. To this end, we propose a log ring cutting device.

[0036] A fixing seat 2111 is fixedly installed on the top of the guide plate 2108, and the number of fixing seats 2111 is two. A pulley 2112 is rotatably installed on one side of the fixing seat 2111, and a fixing shaft 2113 is fixedly installed on one side of the pulley 2112.

The surface of 110 can make the guide plate 2108 more stable during the movement by setting the fixed seat 2111, the pulley 2112 and the fixed shaft 2113, so that the cutting disc 2203 can be driven to be more stable when performing ring cutting on the logs, thereby ensuring the quality and efficiency of the ring cutting. By setting the mounting shaft 2110, the multiple telescopic rod 2105 and the guide plate 2108 can be moved, and the guide plate 2108 will not be stuck when the multiple telescopic rod 2105 drives the guide plate 2108 to move.

[0037] A guide rod 2109 is fixedly installed on the top of the guide plate 2108, and a guide groove 2106 used in conjunction with the guide rod 2109 is provided in the inner cavity of the ring cutting guide plate 2103. The guide rod 2109 is slidably installed in the inner cavity of the guide groove 2106. By setting the guide rod 2109 and the guide groove 2106 to be used in conjunction with each other, the guide plate 2108 can drive the guide rod 2109 to move in the inner cavity of the guide groove 2106 more stably, and in the process of ring cutting the logs, the cutting disc 2203 can be prevented from having a trajectory deviation.

[0038] The cutting unit 22 includes a positioning plate 2202, one side of the positioning plate 2202 is fixedly mounted on the output end of the electric telescopic rod 2104, a second motor 2201 is fixedly mounted on one side of the positioning plate 2202, the output end of the second motor 2201 passes through the inner cavity of the positioning plate 2202, the inner cavity of the positioning plate 2202 is rotatably connected to a sprocket 2207, the number of the sprockets 2207 is two, the output end of the second motor 2201 is fixedly connected to one side of one of the sprockets 2207, the two sprockets 2207 are of different sizes, the inner cavity of the positioning plate 2202 is provided with a chain 2208, the chain 2208 is sleeved on the surfaces of the two sprockets 2207, and the two sprockets 2207 are rotatably connected to the inner cavity of the positioning plate 2202 through bearings , a mounting plate 2204 is slidably mounted on the bottom of the positioning plate 2202, a gear 2206 is fixedly mounted on one side of one sprocket wheel 2207, a cutting disc 2203 is rotatably connected between the positioning plate 2202 and the mounting plate 2204, a tooth 2205 is provided on the surface of the cutting disc 2203, the gear 2206 meshes with the tooth 2205, a mounting ring 2209 is fixedly mounted on the opposite side of the positioning plate 2202 and the mounting plate 2204, a mounting groove 2210 for use with the mounting ring 2209 is provided on the surface of the cutting disc 2203, the mounting ring 2209 is embedded in the inner cavity of the mounting groove 2210, the thickness of the cutting disc 2203 is greater than the thickness of the positioning plate 2202, and both sides of the cutting disc 2203 are conical;

[0039] A dovetail block 2211 is fixedly installed on the top of the mounting plate 2204, and there are two dovetail blocks 2211. A dovetail groove 2214 used in conjunction with the dovetail block 2211 is provided at the bottom of the positioning plate 2202. The surface of the dovetail block 2211 contacts the inner cavity of the dovetail groove 2214. By setting the dovetail block 2211 and the dovetail groove 2214 to be used in conjunction with each other, the mounting plate 2204 can drive the dovetail block 2211 to move in the inner cavity of the dovetail groove 2214, thereby driving one of the mounting rings 2209 to detach from the inner cavity of one of the mounting grooves 2210. Then, the user pulls the cutting disc 2203 to remove the cutting disc 2203, and then replaces it with a new cutting disc 2203.

[0040] A mounting block 2212 is fixedly installed on the top of the mounting plate 2204, and the number of mounting blocks 2212 is two. A mounting hole 2215 used in conjunction with the mounting block 2212 is opened on one side of the positioning plate 2202. The inner cavity of the mounting block 2212 is threadedly connected with a bolt 2213, and one end of the bolt 2213 is threadedly connected to the inner cavity of the positioning plate 2202. By setting the mounting block 2212, the mounting hole 2215 and the bolt 2213 for coordinated use, the bolt 2213 can be screwed into the inner cavity of the positioning plate 2202, so that the mounting block 2212 can be positioned, and the mounting ring 2209 can be positioned so that the mounting ring 2209 will not be separated from the inner cavity of the mounting groove 2210, so that the cutting disk 2203 is more stable during the rotation process, and the phenomenon of the cutting disk 2203 falling off can be avoided at the same time;

[0041] The inner cavity of the mounting ring 2209 is rotatably connected with a supporting wheel 2216, and the number of the supporting wheels 2216 is several. A rotating shaft 2217 is fixedly installed on both sides of the supporting wheel 2216, and one end of the rotating shaft 2217 penetrates the outer side of the mounting ring 2209. An inclined plate 2218 is fixedly installed on the top of the workbench 11. By setting the supporting wheel 2216 and the rotating shaft 2217 for use in coordination, the cutting disc 2203 can be made smoother during the rotation process, avoiding the existence of large friction force that causes the rotation speed of the cutting disc 2203 to be slow, thereby ensuring the stability when cutting logs;

[0042] By setting up the coordinated use of the ring cutting unit 21 and the cutting unit 22, the purpose of ring cutting of the logs can be achieved. In the process of cutting the logs, the operator does not need to use an overly large cutting disc 2203 to cut the logs. No matter how large the radius of the log is, it can be cut with a smaller cutting disc 2203, thus avoiding the problem of breakage that is prone to occur when using a larger cutting disc 2203, thereby ensuring the efficiency and quality of cutting.

[0043] The specific implementation of this embodiment is as follows: when it is necessary to cut the log, the user positions the log through the three-jaw chuck 13. After the positioning is completed, the user uses the external control switch and the power supply to start the first motor 2102 and the second motor 2201. The start of the second motor 2201 drives one of the sprockets 2207 to rotate. During the rotation of one of the sprockets 2207, the other sprocket 2207 is driven to rotate through the chain 2208. Since the two sprockets 2207 are of different sizes, when the large sprocket 2207 drives the small sprocket 2207 to rotate, the rotation speed of the small sprocket 2207 will be faster, and the small sprocket 2207 will rotate faster. 07 drives the gear 2206 to rotate during the rotation process, and the rotation of the gear 2206 drives the cutting disc 2203 to rotate through the teeth 2205. The cutting disc 2203 rotates during the rotation process through the cooperation of the mounting ring 2209 and the mounting groove 2210. At the same time, the supporting wheel 2216 and the rotating shaft 2217 can also ensure the smoothness and stability of the cutting disc 2203 during the rotation. Since the thickness of the cutting disc 2203 is greater than the thickness of the positioning plate 2202, when the cutting disc 2203 cuts the log and gradually cuts to the innermost part of the log, the positioning plate 2202 will not hinder the cutting, and the cutting disc 2203 rotates at the same time. When the cutting disc 2203 is cut, the first motor 2102 drives the multi-telescopic rod 2105 to rotate. The rotation of the multi-telescopic rod 2105 drives the guide plate 2108 to move through the mounting shaft 2110. The movement of the guide plate 2108 drives the fixed seat 2111 to move. The movement of the fixed seat 2111 drives the pulley 2112 to move, so that the pulley 2112 slides in the inner cavity of the circular cutting guide plate 2103 to ensure the stability of the cutting disc 2203. During the rotation of the guide plate 2108, the guide rod 2109 and the electric telescopic rod 2104 are driven to move at the same time, so that the guide rod 2109 moves in the inner cavity of the guide groove 2106. The electric telescopic rod 2104 is moved. The movement of 104 drives the positioning plate 2202 to move, thereby driving the rotating cutting disc 2203 to perform circular cutting on the log, so that the cutting disc 2203 cuts the log step by step, and finally cuts the log, and then the cut wood is rolled down by the inclined plate 2218, thereby achieving the purpose of circular cutting of the log. In the process of cutting the log, the operator does not need to use an overly large cutting disc 2203 to cut it. No matter how large the radius of the log is, it can be cut with a smaller cutting disc 2203, avoiding the problem of breakage when using a larger cutting disc 2203, thereby ensuring the efficiency and quality of cutting.

[0044] Example 2: Please refer to Figure 1-Figure 9 The present invention provides a technical solution: a log ring cutting device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0045] As a further limitation of the ring cutting mechanism 2 of the present invention, an adjustment mechanism 3 is provided at the bottom of the workbench 11, and the adjustment mechanism 3 is provided on one side of the ring cutting unit 21. The adjustment mechanism 3 cooperates with the ring cutting unit 21 and the cutting unit 22, and the adjustment mechanism 3 is used to adjust the positions of the ring cutting unit 21 and the cutting unit 22;

[0046] The adjusting mechanism 3 includes a shell 301, which is fixedly installed at the bottom of the workbench 11, a fixed shell 302 is fixedly installed on one side of the shell 301, a third motor 304 is fixedly installed on the inner wall of the fixed shell 302, a threaded rod 305 is fixedly installed on the output end of the third motor 304, a threaded sleeve 306 is threadedly connected to the surface of the threaded rod 305, a connecting rod 307 is fixedly installed on one side of the threaded sleeve 306, one end of the connecting rod 307 passes through the fixed shell 302 and extends to the inner cavity of the shell 301, an adjusting rod 303 is fixedly installed on one end of the connecting rod 307, the adjusting rod 303 is slidably installed in the inner cavity of the shell 301, one end of the adjusting rod 303 passes through the outer side of the shell 301 and is fixedly connected to one side of the fixed plate 2101, by setting the adjusting mechanism 3, the purpose of adjusting the length of the cut log can be achieved, the operator can make adjustments according to different cutting requirements to ensure that the length of the cut log is in an ideal state, and further ensure the quality and efficiency of the log cutting;

[0047] One side of the shell 301 and the fixed shell 302 is provided with a movable groove for use with the connecting rod 307. One end of the threaded rod 305 is rotatably connected to the inner cavity of the fixed shell 302 through a bearing. By setting the movable groove, sufficient moving space can be provided for the movement of the connecting rod 307.

[0048] The specific implementation of this embodiment is as follows: before cutting the log, when the user needs to fix the cutting length, the user uses the external control switch and the power supply to start the third motor 304, the start of the third motor 304 drives the threaded rod 305 to rotate, the rotation of the threaded rod 305 drives the threaded sleeve 306 to move, the movement of the threaded sleeve 306 drives the connecting rod 307 to move, the movement of the connecting rod 307 drives the adjusting rod 303 to move, the movement of the adjusting rod 303 drives the fixed plate 2101 to move, and the fixed plate 2101 can drive the circular cutting guide plate during the movement. When the circular cutting guide plate 2103 is moved to the required position, the log can have a longer length in the cutting area. During the movement of the circular cutting guide plate 2103, the electric telescopic rod 2104 is started by the external power supply and control switch. The electric telescopic rod 2104 is extended or contracted according to the moving distance of the circular cutting guide plate 2103, so that the position of the cutting disc 2203 can be kept unchanged, thereby achieving the purpose of adjusting the length of the cut log. The operator can make adjustments according to different cutting requirements to ensure that the length of the log after cutting is in an ideal state, further ensuring the quality and efficiency of log cutting.
