Description

Technical Field

[0001] This invention belongs to the field of wood processing technology, specifically referring to a raw material pretreatment device for wood carving construction. Background Technology

[0002] Before commencing wood carving, scientific pretreatment of raw materials is crucial for ensuring the quality of the artwork, with drying being particularly important. Proper drying effectively controls the moisture content of the wood, preventing deformation and cracking caused by uneven moisture evaporation after carving, thus ensuring the dimensional stability and structural durability of the wood carving. Balsa wood, a distinctive raw material for wood carving, boasts extremely low density (only 0.1-0.2 g / cm³), excellent processing properties, and multiple functional characteristics such as heat insulation, sound insulation, and buoyancy, demonstrating unique application value in specific fields such as aerospace models, architectural decoration, and functional art pieces.

[0003] The existing raw material pretreatment equipment for wood carving construction currently has the following problems:

[0004] Existing pre-treatment equipment for wood carving construction lacks the ability to dry the wood from the inside, resulting in inconsistent humidity levels inside and outside the dried wood, which affects the drying efficiency. Furthermore, traditional pre-treatment equipment for wood carving construction also lacks the ability to grind the surface of the wood during the drying process. Therefore, it cannot meet the current needs for pre-treatment equipment for wood carving construction. Summary of the Invention

[0005] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides a raw material pretreatment device for wood carving construction that can guide hot air from inside the wood to ensure that the wood is dried at the same degree inside and out, and can also grind the surface of the wood.

[0006] The technical solution adopted in this plan is as follows: This plan proposes a pre-treatment equipment for raw materials used in wood carving construction, comprising a base, a guide cylinder mounted on the base, a positioning cylinder connected to the guide cylinder, a sealed air-grinding mechanism mounted above the positioning cylinder, and a vertical pressure drying mechanism mounted on the base; the sealed air-grinding mechanism includes: a lifting assembly: lifting frames symmetrically arranged on both sides of the positioning cylinder, a threaded rod penetrating the lifting frame, a threaded block threadedly connected to the threaded rod, and a lifting motor driving the threaded rod; an air-guiding assembly: an air-guiding frame slidably mounted on the top of the lifting frame, an annular plate connecting the threaded block, a metal telescopic cylinder connecting the air-guiding frame and the annular plate, and a rubber ring at the end of the metal telescopic cylinder; a driving assembly: an annular groove within the annular plate, a motor base fixed to the side of the annular plate, a leveling motor mounted on the motor base, a rotating annular external gear disc within the annular groove, and a ring below the motor base. The linkage plate on the side wall of the shaped plate, the linkage gear located between the linkage plate and the motor base and meshing with the annular external gear disk, the drive gear located on the bottom wall of the motor base and meshing with the linkage gear, and the power end of the leveling motor passing through the motor base and connected to the drive gear; the leveling assembly: a leveling ring fixed to the inner wall of the annular external gear disk, and a grinding block located on the inner wall of the leveling ring; the vertical pressure drying mechanism includes: a heating assembly: a hot air frame fixed to the side wall of the lifting frame, a hot air cylinder located between the bottom wall of the hot air frame and the positioning cylinder with an open bottom, a heater located on the side wall of the hot air cylinder, the heating end of the heater located inside the hot air cylinder, and a filter layer located at the bottom of the hot air cylinder; an air supply assembly: an air supply cylinder located inside the air guide frame with an open bottom, a suction pump located on the air supply cylinder, a suction hose connecting the hot air cylinder and the suction pump, a humidity sensor located inside the guide cylinder, and an outlet located on the side wall of the guide cylinder.

[0007] As a further preferred embodiment of the present invention, the vertical pressure drying mechanism further includes a fixing component, which includes a telescopic cylinder disposed on the base, a drive frame disposed on one side of the air guide frame, a drive shaft passing through the hot air frame and disposed between the telescopic cylinder extension end and the drive frame, an upper rubber ring disposed on the top wall of the air delivery cylinder, a lower rubber ring disposed on the bottom of the positioning cylinder, and positioning short spikes passing through the upper rubber ring and the lower rubber ring respectively disposed on the top wall of the air delivery cylinder and the bottom of the positioning cylinder.

[0008] In operation, the lifting motor drives the threaded rod to rotate via the power end. The threaded rod, through the threaded block, drives the annular plate to slide upward along the inner wall of the lifting frame. The annular plate then drives the grinding block to the top of the lifting frame. The balsa wood for wood carving is placed vertically on the bottom wall of the positioning cylinder. After the balsa wood to be carved is fixed, the lifting motor drives the threaded rod to rotate via the power end. The threaded rod, through the threaded block, drives the annular plate to descend. The annular plate, through the annular external gear disc, drives the grinding block to fit onto the outside of the balsa wood. The grinding block fits tightly against the outer wall of the balsa wood. Driven by the threaded block, the grinding block descends slowly and continuously. The leveling motor drives the drive gear to rotate via the power end. The drive gear, through the linkage gear, drives the annular external gear disc to rotate inside the annular groove. The annular external gear disc, through the leveling ring, drives the grinding block to grind the outer surface of the balsa wood, making the outer surface of the balsa wood relatively flat.

[0009] Preferably, the length of the positioning short thorn is less than the length of the upper and lower rubber rings, and the positioning short thorn is located inside the upper and lower rubber rings respectively. When the upper and lower rubber rings are deformed by pressure, the positioning short thorn penetrates the end face of the wood to prevent rotational displacement.

[0010] Preferably, the metal telescopic cylinder and the rubber ring form a sealed cavity for collecting the hot air seeping from the surface of the wood and maintaining the flow of hot air along the axial direction of the wood.

[0011] Preferably, the grinding block grinds the wood surface during its descent, pressing wood chips into the surface micropores to form a physical blockage and reduce the lateral escape of hot air.

[0012] Preferably, the lifting assembly and the fixing assembly are linked and controlled: the telescopic cylinder drives the upper rubber ring to press down and fix the wood; the lifting motor drives the grinding block to descend and complete the surface leveling; the air pump injects hot air into the wood through the air delivery cylinder and discharges it from the bottom through the guide cylinder.

[0013] Preferably, the humidity sensor monitors the humidity of the exhaust gas in real time, and automatically terminates the drying process when the humidity reaches the target level.

[0014] In use, the balsa wood to be carved is placed between the upper and lower rubber rings. The power end of the telescopic cylinder shortens, driving the drive frame to descend via the drive shaft. The drive frame drives the air guide frame to slide down along the lifting frame. The air guide frame, through the air supply cylinder, causes the upper rubber ring to fit tightly against the top wall of the balsa wood. The upper and lower rubber rings deform under the pressure from both sides of the balsa wood. The length of the compressed upper and lower rubber rings is less than the length of the positioning spur. The positioning spur penetrates into the interior of the balsa wood, overcoming the circumferential rotational force on the balsa wood and causing it to deflect.

[0015] Specifically, a controller is provided on the side wall of the heater.

[0016] The controller is electrically connected to the lifting motor, leveling motor, heater, air pump and telescopic cylinder respectively.

[0017] The beneficial effects achieved by this solution using the above structure are as follows:

[0018] Compared with existing technologies, this solution combines a sealed air-grinding mechanism with a vertical pressure drying mechanism. By incorporating a lifting assembly, air guiding assembly, driving assembly, leveling assembly, heating assembly, air supply assembly, and fixing assembly, the rotating grinding block grinds uneven areas on the outer surface of the balsa wood, maintaining a relatively smooth surface. With the metal telescopic cylinder and rubber ring sealing the surface, hot air entering the balsa wood can penetrate from the top to the bottom, effectively drying the internal moisture. Furthermore, the grinding process... Mechanical friction removes burrs and uneven parts from the balsa wood surface, while simultaneously pressing fine wood chips and dust into the surface micropores, forming physical blockages and reducing gas escape channels. This ensures that airflow can penetrate the entire balsa wood. A small portion of the hot air seeping from the balsa wood surface enters the sealed cavity formed by the metal telescopic cylinder and rubber ring. On the one hand, this dries the balsa wood surface; on the other hand, the seeping hot air gradually increases the pressure inside the cavity formed by the metal telescopic cylinder and rubber ring, further maintaining the flow path of the hot air and improving the drying efficiency of the balsa wood interior.

The length of the positioning spikes 45 is less than the length of the upper rubber ring 43 and the lower rubber ring 44. The positioning spikes 45 are located inside the upper rubber ring 43 and the lower rubber ring 44, respectively.

[0040] The heater 30 is provided with a controller 40 on its side wall.

[0041] The controller 40 is electrically connected to the lifting motor 9, the leveling motor 18, the heater 30, the air pump 34, and the telescopic cylinder 37, respectively.

[0042] In actual use, the controller 40 controls the start of the lifting motor 9. The lifting motor 9 drives the threaded rod 7 to rotate through the power end. The threaded rod 7 is threadedly connected to the threaded block 8. The threaded rod 7 drives the annular plate 12 to slide and rise along the inner wall of the lifting frame 6 through the threaded block 8. The annular plate 12 drives the grinding block 25 to rise below the air delivery cylinder 33. The threaded block 8 and the air guide frame 11 maintain a distance. At this time, the metal telescopic cylinder 13 is shortened.

[0043] The balsa wood for wood carving is placed vertically between the upper rubber ring 43 and the lower rubber ring 44. The controller 40 controls the telescopic cylinder 37 to start. The power end of the telescopic cylinder 37 shortens and drives the drive frame 38 to descend through the drive shaft 39. The drive frame 38 drives the air guide frame 11 to slide down along the outside of the lifting frame 6. The air guide frame 11 drives the upper rubber ring 43 to fit tightly against the top wall of the balsa wood through the air supply cylinder 33. The upper rubber ring 43 and the lower rubber ring 44 deform during the compression of the balsa wood. The length of the upper rubber ring 43 and the lower rubber ring 44 after compression is less than the length of the positioning short thorn 45. The positioning short thorn 45 penetrates into the interior of the balsa wood and deflects after overcoming the circumferential rotational force on the balsa wood, thus completing the positioning operation of the wood.

[0044] After the balsa wood to be carved is fixed, the controller 40 controls the lifting motor 9 to start. The lifting motor 9 drives the threaded rod 7 to rotate through the power end. The threaded rod 7 drives the annular plate 12 to descend through the threaded block 8. The annular plate 12 drives the grinding block 25 to fit onto the outside of the balsa wood through the annular outer gear disc 19. The grinding block 25 fits tightly with the outer wall of the balsa wood. Under the drive of the threaded block 8, it descends slowly and continuously. The controller 40 controls the leveling motor 18 to start. The leveling motor 18 drives the drive gear 22 to rotate through the power end. The drive gear 22 drives the annular outer gear disc 19 to rotate inside the annular groove 16 through the linkage gear 21. The annular outer gear disc 19 drives the grinding block 25 to rotate through the leveling ring 24 to grind the outer surface of the balsa wood, making the outer surface of the balsa wood relatively flat. The wood chips produced by grinding fall into the positioning cylinder 3.

[0045] At the same time, the controller 40 controls the heater 30 to start, and the heater 30 heats the air inside the hot air cylinder 29 through the heating end. The controller 40 controls the vacuum pump 34 to start, and the vacuum pump 34 draws hot air from inside the hot air cylinder 29 through the vacuum hose 35. The hot air is delivered to the air delivery cylinder 33 through the exhaust end of the vacuum pump 34. Under the sealing of the upper rubber ring 43, the hot air continuously accumulates inside the air delivery cylinder 33. Because balsa wood has high porosity and low density, the hot air can penetrate a long distance into the wood. At this time, the accumulated hot air rushes into the interior of the balsa wood.

[0046] During the descent, the grinding block 25 grinds the surface of the wood, pressing the wood chips into the surface micropores to form a physical blockage, reducing the lateral escape of hot air. During the descent, the ring plate 12 drives the grinding block 25 to perform leveling and polishing operations on the balsa surface, which reduces the porosity of the balsa surface, reduces the amount of hot air seeping out from the surface, and ensures that more hot air can flow down along the interior of the balsa, allowing for thorough drying of its interior.

[0047] In addition, the annular plate 12 is driven to fit onto the outside of the balsa wood by the deformation of the rubber ring 14. The metal telescopic cylinder 13 extends as the annular plate 12 descends. The metal telescopic cylinder 13 stores the hot air that seeps out of the balsa wood surface, ensuring that the hot air can flow from the top of the balsa wood to the bottom of the balsa wood.

[0048] The hot air flowing out from the top of the balsa wood enters the interior of the guide tube 2 through the positioning tube 3. The controller 40 controls the humidity sensor 41 to start. The humidity sensor 41 detects the humidity of the gas entering the guide tube 2 through the detection end. When the humidity of the outflowing gas meets the operator's standard, the hot air filling into the balsa wood is stopped, and the drying operation of the wood is completed.

[0049] The controller 40 controls the telescopic cylinder 37 to start. The power end of the telescopic cylinder 37 extends, causing the upper rubber ring 43 and the positioning short spike 45 to move away from the top of the balsa wood. The controller 40 controls the lifting motor 9 to start. The lifting motor 9 drives the annular plate 12 to rise through the threaded block 8. The air guide frame 11 and the annular plate 12 are reset to their initial states respectively. The threaded block 8 and the air guide frame 11 maintain a distance.

[0050] Remove the dried wood from inside the positioning cylinder 3, place new wood inside, and complete the drying process for the balsa wood; repeat the above process for the next use.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this.
