[0002] Wood board is a common building and furniture material. The raw materials of wood boards may have various irregular defects during the growth process, which may cause dents, cracks and other problems on the surface of the wood boards after they are made. Therefore, the surface defects of the wood boards need to be repaired.

[0003] The existing repair methods are mostly to pour a special repair liquid for the board into the surface defects of the wooden board and use a trowel to level it. The operation process is similar to wall leveling. However, since the surface defects on the wooden board are usually small in area, there is no need to apply the repair liquid to the entire surface of the wooden board. After the repair, excess repair liquid remains on the surface of the wooden board, affecting the overall flatness of the wooden board. When using a scraper to remove the remaining repair liquid, the repair liquid needs to be pushed to the edge of the wooden board, which will also cause more repair liquid to contact and adhere to the surface of the wooden board, destroying the flatness and cleanliness of the wooden board.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0020] The invention is mainly used for repairing defects on the surface of a wooden board using a repair liquid, and solves the technical problem that the excess repair liquid adheres to the surface of the wooden board and is difficult to remove, thus affecting the flatness of the surface of the wooden board.

[0021] like Figure 1-Figure 9As shown, this embodiment includes a repair and leveling mechanism 100 and a repair mold 200, wherein the repair and leveling mechanism 100 is arranged in the repair mold 200, and the repair and leveling mechanism 100 includes a leveling scraper 101, and the bottom end of the leveling scraper 101 contacts with the surface of the wooden board, and the repair mold 200 includes a cylindrical mold 201, and the length of the repair and leveling mechanism 100 is equal to the inner diameter of the cylindrical mold 201, and the leveling scraper 101 is provided with a central shaft 103, and the central shaft 103 is rotatably arranged at the position of the central axis of the cylindrical mold 201, and the leveling scraper 101 rotates inside the cylindrical mold 201 through the central shaft 103, and both ends of the central shaft 103 contact with the inner wall of the cylindrical mold 201, and the leveling scraper 101 is provided with a balancing elastic component 102, and the balancing elastic component 102 is used to keep the bottom end of the leveling scraper 101 in contact with the surface of the wooden board.

[0022] In this embodiment, a leveling scraper 101 is arranged to always keep in contact with the surface of the wooden board, and the leveling scraper 101 is rotatably arranged in the cylindrical mold 201. When the leveling scraper 101 rotates, the repair liquid on the surface of the wooden board can be evenly spread to ensure that the surface of the wooden board after repair maintains the flatness. At the same time, the cylindrical mold 201 is cylindrical. When the leveling scraper 101 rotates, both ends of the rotating shaft always keep in contact with the inner wall of the cylindrical mold 201 to avoid the repair liquid being squeezed into the gap between the leveling scraper 101 and the cylindrical mold 201. During the rotation of the leveling scraper 101, the repair liquid on the surface of the wooden board is leveled. At the same time, the centrifugal force generated during the rotation discharges the excess repair liquid into the cylindrical mold 201 to avoid excess repair liquid remaining on the surface of the wooden board.

[0023] The balancing elastic component 102 proposed in this embodiment is symmetrically arranged on both sides of the rotating shaft of the leveling scraper 101. The elastic force generated by the balancing elastic component 102 presses the leveling scraper 101 against the surface of the wooden board. At the same time, since the balancing elastic component 102 is symmetrically arranged, it ensures that the bottom end of the leveling scraper 101 is in full contact with the surface of the wooden board, avoiding a gap between the leveling scraper 101 and the surface of the wooden board.

[0024] When this embodiment is used, the position of the defect on the surface of the wooden board is first determined, and the cylindrical mold 201 is placed on the defect position on the surface of the wooden board to ensure that the cylindrical mold 201 completely covers the surface defect of the wooden board. At this time, the balancing elastic component 102 generates elastic force to press the bottom end of the leveling scraper 101 against the surface of the wooden board; Subsequently, the repair liquid is poured onto the surface of the wooden board, and a rotational torque is applied to the central shaft 103. The central shaft 103 drives the leveling scraper 101 to rotate in the cylindrical mold 201. During the rotation of the leveling scraper 101, the repair liquid is pushed to flow on the surface of the wooden board to fill and repair the surface defects of the wooden board. As the leveling scraper 101 rotates, the repair liquid is pushed to circulate continuously on the surface of the wooden board until all surface defects are repaired and there are no gaps for the remaining wooden board repair liquid to enter. At this time, the centrifugal force generated by the rotation of the leveling scraper 101 throws the excess repair liquid onto the cylindrical mold 201, thereby discharging the excess repair liquid into the cylindrical mold 201, and no repair liquid will remain on the surface of the wooden board, thereby ensuring that the surface of the wooden board remains flat and is not contaminated.

[0025] The balancing elastic component 102 proposed in this embodiment includes a top sleeve 104, a bottom connecting rod 105 and a compression spring 106. The bottom connecting rod 105 is fixedly connected to the leveling scraper 101, and the top sleeve 104 is slidably set on the bottom connecting rod 105. The two ends of the compression spring 106 are respectively connected to the top sleeve 104 and the bottom connecting rod 105. The top sleeve 104 is in contact with the cylindrical mold 201, and the elastic force generated by the compression spring 106 presses the top sleeve 104 against the cylindrical mold 201.

[0026] The structure of the balancing elastic component 102 proposed in this embodiment includes a top sleeve 104, a bottom connecting rod 105 and a compression spring 106. There can be relative movement between the top sleeve 104 and the bottom connecting rod 105. At the same time, the compression spring 106 is arranged between the top sleeve 104 and the bottom connecting rod 105. During specific use, the top sleeve 104 is pressed against the top surface of the cylindrical mold 201, and the bottom connecting rod 105 is arranged on the leveling scraper 101. The elastic force generated by the compression spring 106 presses the top sleeve 104 against the top surface of the cylindrical mold 201, and the generated reaction force also acts on the leveling scraper 101 through the bottom connecting rod 105, thereby pressing the bottom connecting rod 105 against the surface of the wooden board, ensuring that the leveling scraper 101 maintains a good contact state with the surface of the wooden board.

[0027] At the same time, two balancing elastic components 102 are arranged on the leveling scraper 101. The two balancing elastic components 102 are equidistant from the rotating shaft of the leveling scraper 101. The balancing torque generated can avoid the warping and deflection of the leveling scraper 101 and improve the contact effect between the leveling scraper 101 and the wooden board surface.

[0028] The top surface of the cylindrical mold 201 proposed in this embodiment is provided with a central through hole 204, the central axis of the central through hole 204 coincides with the central axis of the cylindrical mold 201, the central rotating shaft 103 is rotatably arranged in the central through hole 204, and the central rotating shaft 103 is provided with a central shaft shoulder 107 and a sleeve connecting rod 108, the central shaft shoulder 107 is clamped on the central through hole 204, and the sleeve connecting rod 108 is connected to the top sleeve 104.

[0029] The cylindrical mold 201 proposed in this embodiment has a central through hole 204 at the central axis position, and the central shaft 103 is rotatably set on the central through hole 204. At the same time, a central shaft shoulder 107 is set on the central shaft 103 to ensure that the central shaft 103 will not slip out of the central through hole 204.

[0030] At the same time, a sleeve connecting rod 108 is provided on the central rotating shaft 103, and the sleeve connecting rod 108 is connected to the top sleeve 104. When the central rotating shaft 103 drives the leveling scraper 101 to rotate, it can also drive the balancing elastic component 102 to rotate at the same angular velocity as the leveling scraper 101, so that the leveling scraper 101 can maintain good contact with the surface of the wooden board during rotation.

[0031] In this embodiment, a rotating handle 109 is provided at the top of the central rotating shaft 103. During specific use, the operator can apply a rotational torque to the central rotating shaft 103 by rotating the handle 109. When repairing defects on wooden boards with fewer defects, using the rotating handle 109 can reduce the overall weight of the repair and leveling mechanism 100, making the surface defect repairing device lighter and more labor-saving when transferring between multiple wooden boards.

[0032] The rotating handle 109 proposed in this embodiment can also be disassembled and replaced with automated equipment such as a motor. When repairing a wooden board with a large number of defects, the rotating handle 109 can be replaced with a torque motor or a hydraulic motor. Although this increases the complexity and weight of the overall structure to a certain extent, it can greatly reduce the operator's workload and improve the efficiency of surface defect repair.

[0033] The surface defect repairing device proposed in this embodiment also includes a repairing liquid supply mechanism 400. A repairing liquid feed port 205 is provided at the top of the cylindrical mold 201. The repairing liquid supply mechanism 400 is connected to the repairing liquid feed port 205. The repairing liquid feed port 205 is used to add wood board repairing liquid. A completely penetrating bottom discharge port 206 is provided at the bottom of the cylindrical mold 201. The bottom discharge port 206 is used to discharge excess repairing liquid.

[0034] During specific use, the repair liquid supply mechanism 400 supplies repair liquid to the repair liquid feed port 205, and the repair liquid falls onto the surface of the wooden board through the repair liquid feed port 205. The leveling scraper 101 is rotated to push the repair liquid to flow on the surface of the wooden board. The repair liquid repairs the defects on the surface of the wooden board during the flow. After all surface defects on the wooden board are repaired, the leveling scraper 101 pushes excess repair liquid to the position of the bottom discharge port 206, and the excess repair liquid enters the cylindrical mold 201 through the bottom discharge port 206 for collection.

[0035] In this embodiment, a repair liquid feed port 205 is provided on the top for adding repair liquid, ensuring that the repair liquid can be accurately added to the defective position of the wooden board to reduce the waste of repair liquid. At the same time, a bottom discharge port 206 is provided to discharge excess repair liquid to avoid the repair liquid remaining on the surface of the wooden board, which affects the flatness and cleanliness of the wooden board surface.

[0036] The cylindrical mold 201 proposed in this embodiment is provided with a bottom collecting trough 207 on the outside. The bottom collecting trough 207 is located at the bottom of the cylindrical mold 201. The bottom collecting trough 207 corresponds to the position of the bottom discharge port 206. The bottom collecting trough 207 is used to receive the excess repair liquid discharged from the bottom discharge port 206.

[0037] When this embodiment is used, the leveling scraper 101 is rotated to push the repair liquid to flow on the surface of the wooden board. After all surface defects on the wooden board are repaired, the leveling scraper 101 pushes the excess repair liquid to the bottom discharge port 206. The excess repair liquid enters the bottom collecting trough 207 through the bottom discharge port 206 for collection, thereby realizing the cleaning and recovery of the excess repair liquid.

[0038] The surface defect repairing device proposed in this embodiment also includes a mold fixing mechanism 300, and the repairing mold 200 is provided with a fixing bracket 202 and a carrying handle 203. The mold fixing mechanism 300 is fixed in the fixing bracket 202, and the mold fixing mechanism 300 is used to fix the repairing mold 200 on the surface of the wooden board, and the carrying handle 203 is used to carry the repairing mold 200.

[0039] When in use, the cylindrical mold 201 can be moved by the carrying handle 203. After the cylindrical mold 201 is moved to the position where the surface defect is located on the wooden board, the cylindrical mold 201 is fixed on the surface of the wooden board by the mold fixing mechanism 300, so as to avoid displacement of the cylindrical mold 201 during surface repair, thereby ensuring the effect of surface repair.

[0040] The mold fixing mechanism 300 proposed in this embodiment includes a vacuum cylinder 301, a vacuum piston 302 and a fixed suction cup 303. The vacuum piston 302 is slidably arranged in the vacuum cylinder 301. The bottom of the vacuum cylinder 301 is provided with a vacuum hole 304. The mold fixing mechanism 300 is arranged at the bottom of the vacuum cylinder 301. The vacuum piston 302 is provided with a piston pull rod 305. The vacuum cylinder 301 is provided with a one-way exhaust valve 306. The one-way exhaust valve 306 connects the interior of the vacuum cylinder 301 with the outside atmosphere.

[0041] When the cylindrical mold 201 needs to be fixed in this embodiment, the vacuum piston 302 is pulled upward by the piston pull rod 305, and the air above the vacuum piston 302 in the vacuum cylinder 301 is discharged through the one-way exhaust valve 306. At the same time, negative pressure is generated below the vacuum piston 302 in the vacuum cylinder 301. The negative pressure environment sucks the air in the fixed suction cup 303 into the vacuum cylinder 301 through the suction hole 304, and the mold fixing mechanism 300 is adsorbed on the surface of the wooden board through the fixed suction cup 303, thereby achieving fixation of the cylindrical mold 201.

[0042] The repair liquid supply mechanism 400 proposed in this embodiment includes a repair liquid storage tank 401, a repair liquid supply pump 402 and a supply hose 403. The repair liquid supply pump 402 is connected to the repair liquid storage tank 401, and both ends of the supply hose 403 are respectively connected to the repair liquid supply pump 402 and the repair liquid feed port 205. The repair liquid supply pump 402 transports the repair liquid in the repair liquid storage tank 401 to the repair liquid feed port 205 through the supply hose 403.

[0043] When this embodiment is used, the repair liquid in the repair liquid storage tank 401 is transported to the repair liquid feed port 205 through the supply hose 403 by the repair liquid supply pump 402. There is no need to manually add the repair liquid, which improves the degree of automation of the equipment. The appropriate amount of repair liquid can be added according to the area of ​​the surface defect, reducing the waste of the repair liquid.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
