[0004] When the surface of carbonized bamboo boards is planarized in batches, the planer needs to rotate continuously for a long time to plan the boards, which will generate heat. During the processing, the heat generated by the planer needs to be controlled to prevent the heat from causing changes in the internal stress of the bamboo boards, destroying the certain internal structure and stress balance that have been formed during the carbonization process, resulting in uneven internal stress during the subsequent cooling process, causing the bamboo boards to warp and deform, reducing the dimensional accuracy and appearance quality of the bamboo boards; and causing changes in the color of the bamboo boards due to temperature, such as yellowing and browning, which affects the aesthetics of the bamboo boards.

[0037] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0038] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] Example 1, as Figure 1 and Figure 2As shown, a multi-axis rotary planing surface processing device for carbonized bamboo boards according to an embodiment of the present application includes a body 1, and a plurality of rotary planing components 11 are sequentially arranged in the body 1 along the direction from the inlet to the outlet, wherein dust removal covers 12 are respectively arranged between the plurality of rotary planing components 11, and the dust removal covers 12 are externally connected to a fan for removing debris generated by the plurality of rotary planing components 11 during the planing process of the bamboo boards. The rotary planing component 11 is a very mature prior art, which can be understood by technicians in the relevant field and will not be described in detail here.

[0040] like Figure 1 and 2 As shown, a conveying mechanism 2 is further provided inside the machine body 1. The conveying mechanism 2 is arranged along the arrangement direction of the plurality of rotating planing assemblies 11 and is used for carrying and conveying the carbonized bamboo boards.

[0041] It should be noted that if Figure 2 As shown, the multiple rotary planing assemblies 11 in the present application are all provided with power rollers 3. It should be further explained that the power rollers 3 of the multiple rotary planing assemblies 11 are used to drive the cylindrical cutter to rotate and plan the bamboo board. The outer side of the power roller 3 of the rotary planing assembly 11 is provided with a cylindrical cutter for planing. The specific cylindrical cutter can be set to be hollow. Figure 2 The cylindrical cutter sleeved on the outside of the rotary planing assembly 11 is not shown, and is only used to illustrate the position of the rotary planing assembly 11 and the power roller 3 contained therein.

[0042] like Figure 3 As shown, the power roller 3 includes a shell 31, one end of the shell 31 is coaxially connected to a rotary joint 32, a flow equalizer 33 is coaxially mounted inside the shell 31 toward one end of the rotary joint 32, a plurality of flow guides 34 are evenly fixed to the inside of the shell 31 along the circumference, and a power shaft 35 is keyed to the axis of the shell 31. It can be understood that, as shown in FIG. Figure 2 As shown in the figure, the power roller 3 can be driven to rotate by the power device such as the motor in the body 1. The output end of the specific power device is key-connected to the power shaft 35, so that the shell 31 and the guide member 34 therein can be driven to rotate synchronously. The rotary joint 32 is connected to one end of the shell 31 and rotates synchronously with the shell 31, and the end of the rotary joint 32 connected to the external refrigeration equipment remains stationary.

[0043] Specifically, such as Figure 6-Figure 8 As shown, the outer shell 31 is arranged in an annular shape, and a cavity is arranged in the annular outer shell 31. An isolation cabin 311 is coaxially fixed in the cavity. One end of the isolation cabin 311 is fixed to one end of the cavity facing the rotary joint 32, and a distance is left between the other end of the isolation cabin 311 and the other end of the cavity. The isolation cabin 311 divides the cavity into an inner and outer layer connected at one end, and the isolation cabin 311 itself is hollow.

[0044] It should be noted that in the specific embodiment of the present application, the interior of the isolation cabin 311 can be filled with inert gas or vacuumed. This will help the isolation cabin 311 to better isolate the heat between the inner and outer layers of the internal cavity of the outer shell 31, thereby preventing the heat from the inner layer from rushing to the outer layer and affecting the cooling effect of the outer layer.

[0045] It should be noted that the outer layer and the water inlet end of the rotary joint 32 are communicated, and the inner layer and the water outlet end of the rotary joint 32 are communicated. It can be understood that the cold water transported from one side of the rotary joint 32 will enter the outer layer of the outer shell 31 and flow axially to the other end of the outer layer, and then enter the inner cavity of the outer shell 31 through the gap between the isolation cabin 311 and the inner end of the outer shell 31, and then flow axially to the water outlet end of the rotary joint 32, so that a liquid channel is formed inside the outer shell 31.

[0046] Among them, the outer layer in the cavity of the shell 31 faces one end of the rotary joint 32, and its inner wall is symmetrically provided with a recessed portion 312, and the flow equalizer 33 is rotatably embedded in the recessed portion 312 to limit the axial position of the flow equalizer 33.

[0047] Furthermore, a partition 321 is coaxially arranged inside the rotary joint 32. The partition 321 is annular and rotates sealably inside the rotary joint 32. The partition 321 divides the rotary joint 32 into two layers, the outer layer being the water inlet layer and the inner layer being the water outlet layer.

[0048] Specifically, the two ends of the outer layer of the rotary joint 32 are respectively connected to a first water inlet 322 and multiple second water inlets 323. The first water inlet 322 is connected to the outlet of the external refrigeration equipment, and the multiple second water inlets 323 are evenly arranged circumferentially and fixedly connected to the outer cavity of the shell 31.

[0049] Furthermore, the two ends of the inner layer of the rotary joint 32 are respectively connected with multiple first water outlets 324 and second water outlets 325. The multiple first water outlets 324 are evenly arranged circumferentially and fixedly connected to the inner cavity of the outer shell 31, and the second water outlets 325 are connected to the inlet of the external refrigeration equipment.

[0050] It is understandable that the design of the multiple second water inlets 323 and the multiple first water outlets 324 allows the water inside the shell 31 to be distributed as evenly as possible when the water enters the shell 31 and flows back from the shell 31.

[0051] like Figure 4 and Figure 9 As shown, a plurality of arcuate grooves 331 are provided on the flow balancing member 33 along the axial direction. The plurality of arcuate grooves 331 penetrate the flow balancing member 33 and are evenly arranged in the circumferential direction.

[0052] From this, it can be understood that after the cold water enters the outer layer of the shell 31, it will be hindered by the flow equalizer 33, and the water can and can only pass through the multiple arc grooves 331. In this way, under the action of the force generated by the flow of water, the flow equalizer 33 will rotate in the recessed portion 312. It can be understood that the water passing through the flow equalizer 33 at this time will be further evenly distributed.

[0053] like Figure 3 、 Figure 5 、 Figure 6 and Figure 10 As shown, a plurality of flow guides 34 are arranged along the axial direction of the shell 31 , and the flow guides 34 are fixed in the outer cavity of the shell 31 .

[0054] Furthermore, one end of the flow guide 34 is rotatably abutted against the flow equalizer 33 , and the other end of the flow guide 34 is flush with the end of the isolation cabin 311 .

[0055] Among them, a plurality of through holes 341 are provided on the guide member 34, and the through holes 341 communicate with each other on both sides of the guide member 34; the multiple through holes 341 on two adjacent guide members 34 are staggered along the length direction of the guide member 34. It can be understood that the multiple through holes 341 staggered on adjacent guide members 34 allow water to flow between adjacent guide members 34, so as to further compensate for the cold water between the two guide members 34, so that the cold water between the multiple guide members 34 is more evenly distributed.

[0056] Furthermore, guide grooves 342 are symmetrically arranged on both sides of the guide member 34, and the guide grooves 342 are arranged along the length direction of the guide member 34. The design of the guide grooves 342 allows water to flow as much as possible along the length direction between two adjacent guide members 34, thereby reducing the influence of the centrifugal force generated during the rotation of the shell 31 on the flow of water.

[0057] The following describes the use of a carbonized bamboo board multi-axis rotary planing surface processing device according to an embodiment of the present application with reference to the accompanying drawings:

[0058] When in use, move the carbonized bamboo board from the left side of the machine ( Figure 1 and Figure 2The left side shown in the figure is placed on the conveying mechanism 2, and the conveying mechanism 2 conveys the carbonized bamboo board to multiple rotating planing components 11 in sequence, and is planed and planed by the multiple rotating planing components 11, and then output from the right side of the machine body 1. During this process, when the carbonized bamboo board is undergoing the planing and planing process, the power roller 3 continuously conveys cold water through the external refrigeration equipment. The cold water enters the outer layer of the rotary joint 32 through the first water inlet 322 of the rotary joint 32, and then enters the outer layer of the shell 31 through the second water inlet 323, and flows through the flow equalizer 33 to between the multiple guide members 34. During this process, the flow equalizer 33 is rotated by means of fluid power, so that the amount of water entering between the multiple guide members 34 is kept balanced, and the water flows in the multiple guide members. When the cold water flows between the guide members 34, it can flow between two adjacent guide members 34 through multiple through holes 341, further ensuring the balance of water volume between the multiple guide members 34. In the process of the cold water flowing in the outer layer of the shell 31, the heat generated in the planing and planarization process will be absorbed by the shell 31 and carried to the inner layer of the shell 31. The water carries the heat through the inner layer of the shell 31 to the first water outlet 324, and enters the inner layer of the rotary joint 32 through multiple first water outlets 324, and finally flows back to the refrigeration equipment through the second water outlet 325 to complete the cycle. This design allows the heat generated in the planing and planarization process to be continuously carried away, thereby controlling the heat generated in the planing and planarization process.

[0059] In the related art, a multi-axis rotary planing and surface processing device for carbonized bamboo boards is disclosed, in which when cold water flows from the outer layer to the inner layer of the outer shell 31, the outer shell 31 is continuously rotating, and the liquid tends to flow outward under the action of centrifugal force, so that when the outer layer liquid enters the inner layer, mixing will occur in the area, and part of the cold water carrying heat energy will flow back to the outer layer. Although it will not flow in the opposite direction along the flow channel of the outer layer, it will cause the end of the outer shell 31 away from the rotary joint 32 to have a reduced effect on the dissipation of heat energy. Subsequently, in the work of planing and surface processing of large quantities of carbonized bamboo boards, heat will accumulate at this end, affecting the normal processing effect of the carbonized bamboo boards.

[0060] Example 2: According to some embodiments of this application, Figure 5 、 Figure 11-13 As shown, an anti-backflow component 4 is provided at the gap between the isolation cabin 311 and the end of the cavity of the outer shell 31. The anti-backflow component 4 includes a guide ring 41 coaxially fixed to the end of the isolation cabin 311, and the other end of the guide ring 41 is fixed to the inner end of the outer shell 31. A sealing ring 42 is coaxially sealed and slidably provided on the outer side of the guide ring 41. The sealing ring 42 and the outer cavity sealing sliding fit of the outer shell 31, and a plurality of reset parts 43 are evenly arranged circumferentially on the sealing ring 42. One end of the plurality of reset parts 43 is slidably inserted into the sealing ring 42, and the other end of the plurality of reset parts 43 is fixed to the inner end of the outer shell 31.

[0061] It is understood that, in the initial state, the sealing ring 42 is located on the left side of the guide ring 41 due to the elastic action of the reset member 43. Figure 5 and Figure 11 As shown, at this time, the sealing ring 42 blocks the passage between the outer layer and the inner layer of the shell 31 .

[0062] Specifically, a plurality of steering holes 411 are evenly arranged circumferentially on the guide ring 41. The steering holes 411 pass through the guide ring 41. The length of the steering holes 411 along the axial direction is less than the axial length of the guide ring 41. The steering holes 411 are distributed at one end of the guide ring 41 away from the isolation cabin 311.

[0063] Among them, the reset member 43 includes a guide rod 431 and an elastic member 432. One end of the guide rod 431 is fixed to the inner end of the shell 31, and the other end of the guide rod 431 is slidably inserted into the guide ring 41. The elastic member 432 is sleeved on the guide rod 431 and abuts against the guide ring 41 and the inner end of the shell 31.

[0064] Therefore, during specific use, when the cold water enters the outer layer of the shell 31 and gradually flows toward the sealing ring 42, the water on the left side of the sealing ring 42 becomes larger and larger, and the pressure acting on the left side of the sealing ring 42 gradually increases. After the pressure is greater than the pressure provided by the elastic member 432 to the sealing ring 42, the sealing ring 42 begins to move to the right until it moves to the point where the steering hole 411 leaks out. That is, at this time, the outer layer and the inner layer of the shell 31 are connected, and the cold water drills into the steering hole 411 and flows toward the inner layer of the shell 31. In the specific embodiment of the present application, if the cold water wants to enter the inner layer from the outer layer of the shell 31, the pressure it applies to the sealing ring 42 needs to always be greater than the pressure applied to the sealing ring 42 by the elastic member 432. , the water pressure in the outer space will have a certain value, and the water pressure in the inner space will be lower than the water pressure in the outer space. In this way, this design reduces the phenomenon of the inner water body flowing back into the outer water body due to the rotation of the outer shell 31 to a certain extent. At the same time, when the outer water body surges toward the inner layer, the flow rate of the water body will increase due to the reduction of the circulation space (the size of the multiple turning holes 411 is relatively reduced compared to the space when there is no guide ring 41). Therefore, the water body will also generate a certain impact force here to offset the centrifugal force generated by the rotation of the outer shell 31. In this way, the heat dissipation effect of the outer shell 31 at the end where the water body is turned will be guaranteed, avoiding the phenomenon of heat accumulation at this end during long-term use.

[0065] In the related art, in the multi-axis rotary planing surface processing device for carbonized bamboo boards, when the water carries heat and flows back from the inner layer of the outer shell 31 to the rotary joint 32, heat will be accumulated on the inner side of the ring of the outer shell 31 itself. Under long-term use, the heat accumulation there will become more and more, affecting the heat content in the water flowing back to the refrigeration equipment, and generating a larger workload for the refrigeration equipment. At the same time, the accumulated heat will also have a certain negative impact on other components through the power shaft 35.

[0066] Example 3: According to some embodiments of this application, Figure 14 As shown, an air cooling assembly 5 is coaxially arranged at the position where the housing 31 is keyed to the power shaft 35 . The air cooling assembly 5 generates airflow at the axis of the housing 31 by the rotation of the housing 31 .

[0067] The air cooling assembly 5 includes an air inlet blade 51 and an air outlet blade 53 coaxially fixed to both ends of the shell 31 . The air inlet blade 51 and the air outlet blade 53 are in the same direction and are keyed to the power shaft 35 .

[0068] It is understandable that the air inlet blades 51 and the air outlet blades 53 arranged in the same direction can quickly carry away the accumulated heat generated inside the shell 31 by the air flow, avoiding the blockage of air flow inside the shell 31 and affecting the air cooling effect.

[0069] Specifically, the air cooling assembly 5 further includes a plurality of spiral guide bars 52 fixed to the inner wall of the shell 31 . The plurality of spiral guide bars 52 are arranged along the axial direction of the shell 31 , and the plurality of spiral guide bars 52 are evenly arranged in the circumferential direction.

[0070] It can be understood that the provision of multiple spiral guide strips 52 can enable the airflow generated on the inner side of the shell 31 to form multiple spiral airflows during the circulation process, thereby guiding the airflow and avoiding turbulence and other turbulent flow phenomena on the inner side of the shell 31. At the same time, it also forces the airflow to contact the inner side of the shell 31 as comprehensively as possible. Furthermore, the multiple spiral guide strips 52 also increase the contact area between the inner side of the shell 31 and the airflow, thereby further increasing the heat dissipation area.

[0071] Therefore, during actual use, the rotation of the outer shell 31 and the power shaft 35 will drive the air inlet blades 51 and the air outlet blades 53 to rotate synchronously. The same-direction design generates airflow along the power shaft 35 on the inner side of the outer shell 31. After the airflow enters the inner side of the outer shell 31, it is guided by the multiple spiral guide strips 52 to form multiple spiral airflows, which fully contact the inner side of the outer shell 31. At the same time, the contact between the airflow and the multiple spiral guide strips 52 also increases the heat dissipation area. The airflow discharges the accumulated heat generated on the inner side of the outer shell 31 from one end of the air outlet blades 53, accelerates the dissipation of the accumulated heat on the inner side of the outer shell 31, reduces the heat content in the inner layer of the water body of the outer shell 31, and reduces the workload of the external refrigeration equipment.

[0072] It should be noted that the specific models and specifications of the rotary planing assembly 11, dust cover 12, conveying mechanism 2, elastic member 432, air inlet blades 51 and air outlet blades 53 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0073] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
