The two sides of the splicing plate are inclined. When winding the fiber cloth on the surface of the splicing plate, it is considered a successful winding only when the fiber cloth is completely infiltrated with fiberglass resin. When winding, there will be air bubbles in the splicing gap of the wooden core of the splicing plate, making the fiber cloth unable to fully infiltrate the fiberglass resin.

[0041] The stretching unit includes an electric push rod 401, a moving frame 402, a tooth scraping block 403, a first rack 404 and a second rack 405. Two electric push rods 401 are fixedly connected to the inner left wall and the inner right wall of the protective cover 2 respectively. The telescopic parts of the two electric push rods 401 on the left and the telescopic parts of the two electric push rods 401 on the right are fixedly connected with a moving frame 402 respectively. Eight tooth scraping blocks 403 are fixedly connected to the lower parts of the two moving frames 402 at equal intervals. Eight first racks 404 are fixedly connected to the opposite sides of the lower parts of the two moving frames 402, and the sixteen first racks 404 are sequentially located above the sixteen tooth scraping blocks 403. Two second racks 405 are fixedly connected to the opposite sides of the middle parts of the two moving frames 402.

[0042] The conveying unit includes an electric slide rail 501, an electric slider 502, a support rod 503, a third rack 504, a stretching plate 505, an elastic member 506, a fourth rack 507, a fourth transmission shaft 508 and a fourth spur gear 509. Two electric slide rails 501 are symmetrically bolted to the upper surface of the cross-shaped plate 3. Two electric sliders 502 are slidably connected to each of the two electric slide rails 501. A support rod 503 is bolted to the upper surface of each of the four electric sliders 502. A third rack 504 is welded to the lower parts of the two support rods 503 on the left and the lower parts of the two support rods 503 on the right respectively. An elastic member 506 is fixedly connected to the middle parts of the two support rods 503 on the left and the middle parts of the two support rods 503 on the right respectively. One stretching plate 505 is fixedly connected to the two elastic members 506 on the left, and another stretching plate 505 is fixedly connected to the two elastic members 506 on the right. Two fourth racks 507 are fixedly connected to the opposite sides of the two stretching plates 505 and are symmetrically distributed front and back.

[0043] The upper part of the support rod 503 is inclined and has an inclination direction opposite to that of both sides of the splicing board for supporting and fixing the splicing board.

[0044] Working principle: During operation, the operator places the splicing plate obtained by winding the fiber cloth from the front to the back on the support rod 503, which is fixed by the support rod 503. Then, the electric slide rail 501 is controlled to drive the electric slider 502 to move backward. The electric slider 502 drives the support rod 503 to move backward, and the support rod 503 drives the splicing plate to move backward. During the movement, the third rack 504 meshes with the second spur gear 3010 and the third spur gear 3015 respectively and drives the second spur gear 3010 and the third spur gear 3015 to rotate. The second spur gear 3010 drives the second transmission shaft 309 to rotate, and the second transmission shaft 309 drives the second rolling roller 3011 to rotate. The second rolling roller 3011 performs a stabbing operation on the fiber cloth wound on the lower surface of the splicing plate, bringing out the air bubbles and excess fiberglass resin between the lower surface of the splicing plate and the fiber cloth to the surface of the fiber cloth. And the second sector plate 3012 is used to press the fiber cloth into the splicing gap of the splicing plate, making the splicing gap filled with fiberglass resin to increase its viscosity and expelling the air bubbles in the gap. At the same time, the third spur gear 3015 drives the third transmission shaft 3014 to rotate, and the third transmission shaft 3014 drives the roller 3016 to roll-press the fiber cloth on the lower surface of the splicing plate, making the fiber cloth fit more closely with the splicing plate and being wetted more fully. When the splicing plate is transported directly below the protective cover 2, the electric push rod 401 is controlled to extend. The electric push rod 401 drives the moving frame 402 to move towards the splicing plate. The moving frame 402 drives the tooth scraping block 403 to move towards the splicing plate until the first rack 404 meshes with the first spur gear 30704. Then, the driver 301 is controlled to be turned on. The driver 301 drives the first transmission wheel 302 to rotate. The first transmission wheel 302 drives the second transmission wheel 303 to rotate through the belt. The second transmission wheel 303 drives the bidirectional lead screw 305 to rotate. The bidirectional lead screw 305 drives the two connecting plates 30701 to move away from each other on the optical rod 306. The connecting plate 30701 drives the first sector plate 30702 to press the fiber cloth wound on the upper surface of the splicing plate into the splicing gap of the splicing plate, making the splicing gap filled with fiberglass resin and expelling the air bubbles therein, that is, expelling the air bubbles at the splicing part between the wooden cores of the splicing plate. At the same time, the first sector plate 30702 drives the first transmission shaft 30703 to move as well. The first transmission shaft 30703 drives the first spur gear 30704 to move. During the movement, the first spur gear 30704 intermittently meshes with the first rack 404, enabling the first spur gear 30704 to achieve intermittent rotation. The first spur gear 30704 drives the first transmission shaft 30703 to perform intermittent rotation. The first transmission shaft 30703 drives the first rolling roller 30705 to perform intermittent rotation on the upper surface of the splicing plate. The first rolling roller 30705 stabs the fiber cloth wound on the upper surface of the splicing plate. After the acupuncture needle stabs, the pressing rod presses down, bringing out the air bubbles and excess fiberglass resin between the splicing plate and the fiber cloth to the surface of the fiber cloth. Then, the excess fiberglass resin brought out is evenly scraped and coated through the scraper 30706 to wet the fiber cloth.Then, control the electric push rod 401 to contract. The four electric push rods 401 drive the two moving frames 402 to move away from each other, so as to stretch the fiber cloth through the four tooth scraping blocks 403, making the fiber cloth infiltrate the fiberglass more fully.

[0045] Embodiment 3

[0046] On the basis of Embodiment 2, according to Figure 1 and Figure 12-13 As shown, it further includes a fixing unit. The inside of the protective cover 2 is connected with symmetrically distributed fixing units. The fixing unit includes a second bracket 601, a fifth transmission shaft 602, a column gear 603, a rotating plate 604 and a knocking plate 605; Two second brackets 601 are welded to the left inner wall and the right inner wall of the protective cover 2 respectively, and the four second brackets 601 are distributed in two groups of two; A fifth transmission shaft 602 is rotatably connected to each of the two groups of second brackets 601; Seven rotating plates 604 are equidistantly fixed on the outer surfaces of the two fifth transmission shafts 602 respectively; A column gear 603 is fixed to the front end and the rear end of each of the two fifth transmission shafts 602; Fourteen rotating plates 604 are distributed in groups of seven, and a knocking plate 605 is welded to the lower part of each group of rotating plates 604.

[0047] Working principle: When the electric push rod 401 contracts after extending, the electric push rod 401 drives the moving frame 402 to move away from the splicing plate. The moving frame 402 drives the second rack 405 to also move away from the splicing plate. The second rack 405 drives the column gear 603 to rotate. The column gear 603 drives the fifth transmission shaft 602 to rotate. The fifth transmission shaft 602 drives the rotating plate 604 to rotate counterclockwise when viewed from the front to the back around the fifth transmission shaft 602, so that the rotating plate 604 drives the knocking plate 605 to swing and knock on the side of the splicing plate where the fiber cloth is not wound, making the splicing plate fit tighter, breaking the air bubbles in the gap of the splicing plate, and fixing the splicing plate at the same time. When the electric push rod 401 extends, the electric push rod 401 drives the moving frame 402 to move towards the splicing plate. The moving frame 402 drives the second rack 405 to also move towards the splicing plate. The second rack 405 drives the column gear 603 to reset. The column gear 603 drives the fifth transmission shaft 602 to reset, so that the knocking plate 605 leaves the side of the splicing plate. In this way, reciprocating, the two sides of the splicing plate where the fiber cloth is not wound are knocked; This mechanism further removes the air bubbles in the fiber board.

[0050] The four pressing plates 704 are distributed in two groups of two, and two friction rods are arranged on the facing sides of each group of pressing plates 704 for stretching the fiber cloth.

[0051] Working principle: When the rotating plate 604 is not driven to swing, the rotating plate 604 presses tightly against the wedge-shaped plate 702, and the wedge-shaped plate 702 exerts a pressure on the spring telescopic rod 701. When the rotating plate 604 is driven to swing, the rotating plate 604 reduces the extrusion force on the wedge-shaped plate 702, and the spring telescopic rod 701 then exerts an elastic force on the wedge-shaped plate 702, pushing the wedge-shaped plate 702 to move towards the splicing plate. The wedge-shaped plate 702 drives the pressing plate 704 to perform stretching and pressing operations on the fiber cloth on the front side and the rear side of the splicing plate, squeezing out the air bubbles and excess fiberglass resin on the front end face and the rear end face of the splicing plate to achieve the infiltration effect. At the same time, the fifth rack 703 drives the fourth spur gear 509 to rotate, and the fourth spur gear 509 drives the fourth rack 507 to perform a left-right reciprocating movement once. Finally, the fourth rack 507 drives the stretching plate 505 to also stretch the fiber cloth on the lower surface of the splicing plate, so that the entire fiber cloth wound around the splicing plate is fully infiltrated with the fiberglass resin, and the fiber cloth fits more tightly with the splicing plate. This mechanism realizes the infiltration of the fiber cloth on the front end face and the rear end face of the splicing plate.
