A No. 3 spring is arranged between the slide rail and the connecting slide plate, and the connecting slide plate is reset by the No. 3 spring.

[0015] The present invention provides a surface crack repair treatment device for a wood board, which has the following beneficial effects:

[0016] (1) In the present invention, the downward movement of the glue injection machine will drive the elastic telescopic rod to move downward, and the downward movement of the elastic telescopic rod will drive the pulley to move downward. The pulley moves downward and contacts the wood board to limit the wood board and prevent it from warping and affecting the glue injection repair.

The support seat moves toward the middle of the glue injection machine to drive the roller to move toward the middle of the glue injection machine. The roller contacts the wood board to reduce friction and improve the protection effect of the wood.

[0017] (2) The invention drives the connecting plate to move upward by contracting the free end of the elastic telescopic rod. The upward movement of the connecting plate drives the short rod to move upward. The upward movement of the short rod contacts the trapezoidal block, which pushes the trapezoidal block to move away from the injection port. The movement of the trapezoidal block away from the injection port drives the sealing plate to move away from the injection port. The movement of the sealing plate away from the injection port loosens the solution condensed inside the injection port, thereby preventing the injection port from being blocked and affecting the repair efficiency of the wood board. At the same time, the upward rotation of the rotating plate drives the tooth plate to rotate downward. The downward rotation of the tooth plate pushes the stuck gel out of the injection port, thereby preventing the injection port from being blocked due to solidification and affecting the subsequent injection and repair use.

[0018] (3) In the present invention, the upward rotation of the fixed plate will drive the shaft to rotate downward, and the downward rotation of the shaft will drive the scraper to rotate downward. The downward rotation of the scraper will make it contact with the wood board, and the movement of the linear motor will drive the glue injection machine to move. The movement of the glue injection machine will drive the scraper to move. The movement of the scraper will push the excess repair liquid on the wood board into the collection frame for recycling, thereby preventing the repair liquid from being wasted. At the same time, the reset of the connected sliding plate will drive the reset of the scraper. The reset of the scraper will push the repair liquid attached to the scraper into the collection frame, thereby preventing too much repair liquid from being attached to the scraper. After the repair liquid solidifies, it will affect the scraper to smooth the repair liquid, thereby affecting the repair effect. BRIEF DESCRIPTION OF THE DRAWINGS

The wood board is corrected by moving the elastic telescopic plate 14 to the middle of the glue injection machine 6 to prevent the wood board from shifting, resulting in the repair liquid being unable to effectively cover the wood board, causing waste of resources.

[0030] A support seat 15 is fixedly mounted on the surface of the elastic expansion plate 14, and a roller 16 is rotatably mounted on the inner wall of the support seat 15. The roller 16 contacts the wood board to reduce friction and improve the protection effect on the wood.

The movement of the sealing plate 174 in a direction away from the glue injection port 7 will loosen the solution condensed inside the glue injection port 7, thereby preventing the glue injection port 7 from being blocked and affecting the repair efficiency of the wood board.

[0034] A rotating plate 177 is rotatably installed inside the glue injection port 7, a tooth plate 178 is fixedly installed on the top of the rotating plate 177, a connecting rope 176 is fixedly installed on the bottom of the rotating plate 177, and one end of the connecting rope 176 away from the rotating plate 177 is fixedly installed on the bottom of the sealing plate 174. The tooth plate 178 rotates downward to push the stuck gel out of the glue injection port 7 to prevent solidification from causing blockage of the glue injection port 7 and affecting subsequent glue injection repair use.

[0035] The short rod 172 is in contact with the surface of the trapezoidal block 173. A No. 2 spring is arranged between the trapezoidal block 173 and the glue injection machine 6, and the trapezoidal block 173 is reset by the No. 2 spring.

[0036] The scraper device includes an L-shaped rod 181, a rotating shaft 182, a fixed plate 183 and a scraper 184.

[0039] When the present embodiment is working, the free end of the elastic telescopic rod 8 contracts and drives the connecting plate 171 to move upward. The upward movement of the connecting plate 171 drives the short rod 172 to move upward. The upward movement of the short rod 172 contacts the trapezoidal block 173. The short rod 172 pushes the trapezoidal block 173 to move away from the injection port 7. The movement of the trapezoidal block 173 away from the injection port 7 drives the sealing plate 174 to move away from the injection port 7. The movement of the sealing plate 174 away from the injection port 7 causes condensation in the injection port 7. The solution in the part is loosened to prevent the glue injection port 7 from being blocked and affecting the repair efficiency of the wood board. At the same time, the sealing plate 174 moves in the direction away from the glue injection port 7, which drives the connecting rope 176 to move in the direction away from the glue injection port 7. The movement of the connecting rope 176 in the direction away from the glue injection port 7 pulls the rotating plate 177 to rotate upward. The upward rotation of the rotating plate 177 drives the tooth plate 178 to rotate downward. The downward rotation of the tooth plate 178 pushes the stuck gel out of the glue injection port 7 to prevent solidification from causing blockage in the glue injection port 7 and affecting the subsequent glue injection repair.

[0040] The sealing plate 174 moves in a direction away from the glue injection port 7, driving the L-shaped rod 181 to move in a direction away from the glue injection port 7. The L-shaped rod 181 moves in a direction away from the glue injection port 7 and contacts the fixed plate 183. The L-shaped rod 181 pushes the fixed plate 183 to rotate upward. The upward rotation of the fixed plate 183 drives the rotating shaft 182 to rotate downward. The downward rotation of the rotating shaft 182 drives the scraper 184 to rotate downward. The downward rotation of the scraper 184 will contact the wood board, and the glue injection machine 6 is driven to move by the linear motor 3. The movement of the glue injection machine 6 drives the scraper 184 to move. The movement of the scraper 184 will push the excess repair liquid on the wood board into the collection frame 1 for recycling, so as to prevent the repair liquid from being wasted. At the same time, the downward rotation of the scraper 184 will drive the slide rail 185 rotates downward, and the downward rotation of the slide rail 185 will drive the connecting slide 186 to rotate downward. The connecting slide 186 will be pulled by the pull rope 188 when it rotates downward. The pull rope 188 will pull the connecting slide 186 to slide upward. The upward sliding of the connecting slide 186 will drive the scraper 187 to slide upward. When too much repair liquid is attached to the scraper 184, the resetting of the scraper 184 will cause the connecting slide 186 to lose the tension, and the connecting slide 186 will be driven to reset through the No. 3 spring. The resetting of the connecting slide 186 will drive the scraper 187 to reset. The resetting of the scraper 187 will push the repair liquid attached to the scraper 184 into the collecting frame 1 to prevent too much repair liquid from being attached to the scraper 184. After the repair liquid solidifies, it will affect the scraper 184 to smooth the repair liquid, affecting the repair effect.
