[0085] Implementation process:

[0086] Since the edge of the cut plate body 1 is uneven, in order to ensure the verticality of the edge of the plate body 1, the edge of the plate body 1 is first sanded with a sanding machine to make the uneven surface become a vertical surface;

[0087] The edge of the plate body 1 is filled with putty for the first time to form a first putty layer 2. Putty, also known as unsaturated polyester resin putty, is a rapidly developing filling material in the world in the past 20 years. It has the advantages of easy scraping, quick drying at room temperature, easy grinding, strong adhesion, high temperature resistance, good matching, etc. The first putty layer 2 is rolled with a scraper or a roller, and the first putty layer 2 is irradiated with an ultraviolet generating device until it is semi-dry;

[0088] Performing a second putty filling on the first putty layer 2 to form a second putty layer 3, rolling the second putty layer 3 with a scraper or a roller, and irradiating the second putty layer 3 with an ultraviolet generating device until it is semi-dry;

[0089] All R corners of the plate body 1 are finely trimmed to remove excess putty, and the R corner trimmer can be used to achieve fine trimming;

[0090] Performing a third putty filling on the second putty layer 3 to form a third putty layer 4, rolling the third putty layer 4 with a scraper or a roller, and irradiating the third putty layer 4 with an ultraviolet generating device until it is in a semi-dry state;

[0091] The third putty layer 4 is evenly coated with a vacuum spray paint machine 63 to form a paint layer 5, ensuring that the holes at the edge of the plate body 1 are filled and even, and the paint layer 5 is irradiated with an ultraviolet generating device until it is completely dry. Here, the third putty layer 4 is preferably coated with transparent paint, and the formed paint layer 5 is a transparent base;

[0092] Use one of triangular sand, sponge sand or polishing wheel to grind the edge of the plate body 1 to make it smooth and flat, and fine-tune all R angles of the plate body 1 to remove excess paint, which can be achieved again with the help of R angle trimmer;

[0093] Apply a first color base to the paint layer 5 to form a first color base layer 6, and irradiate the first color base layer 6 with an ultraviolet generating device until it is semi-dry;

[0094] Apply a second color base layer to the first color base layer 6 to form a second color base layer 7, and use an ultraviolet generating device to irradiate the second color base layer 7 until it is semi-dry;

[0095] Apply a third color base to the second color base layer 7 to form a third color base layer 8, and irradiate the third color base layer 8 with an ultraviolet light generating device until it is semi-dry;

[0096] Use one of triangular sand, sponge sand or polishing wheel to grind the edge of the plate body 1 to make it flat and smooth, ensure that the color paint is flat and smooth, and fine-tune all R corners of the plate body 1 to remove excess paint, which can be achieved again with the help of R corner trimmer;

[0097] The decorative layer is processed on the entire board body 1, and the surface of the board body 1 can be sprayed with topcoat or printed with wood grain to improve the aesthetics of the board body 1.

[0098] The working principle of the edge sanding machine for sanding the plate body 1 is:

[0099] In the initial state, the piston rod 27 is in a shortened state, the pressing plate 34 is separated from the supporting plate 23, the plate body 1 is placed on the top wall of the supporting plate 23, the first motor, the second motor and the fan 53 are turned on, and the first motor drives the first rotating wheel 10, the first rotating rod 11, the second rotating wheel 12, the first transmission belt 13, and the second transmission belt 14 to rotate, so that the supporting plate 23 and the locking plate 32 move to the right. When the plate body 1 passes between two of the guide strips 37, the plate body 1 is corrected under the guidance of the two guide strips 37 so that the edge of the plate body 1 is aligned with the two grinding wheels 39. After the plate body 1 is corrected, the piston rod 27 on the cylinder 26 is immediately extended, so that the sliding The movable column 28 moves downward to press the plate body 1. When the plate body 1 passes through the two grinding wheels 39, the grinding wheels 39 rotate under the drive of the second motor, and the grinding wheels 39 sand the edge of the plate body 1. The flying debris is sucked into the chip feeding channel 58 by the fan 53, passes through the chip feeding channel 58 and falls onto the detection plate 15 in the box cavity 57, reducing the difficulty of later cleaning. When the plate body 1 moves to the front of the steering mechanism, since the first permanent magnet 33 is located below the second permanent magnet 45 at this time, the magnetic attraction of the second permanent magnet 45 attracts the first permanent magnet 33, and the first permanent magnet 33 drives the sliding plate 31 and the locking plate 32 to move upward, and the locking plate 32 is separated from between the two limit plates 35. , the locking piece 32 releases the limit on the pressure plate 34, the first gear 36 and the transmission rack 43 are meshed for a period of time, so that the transmission rack 43 will drive the first gear 36, the pressure plate 34, the plate body 1 and the support plate 23 to rotate ninety degrees. When the plate body 1 moves to the right of the steering mechanism, the sliding piece 31 and the locking piece 32 move downward under the elastic force of the first elastic member 30, and the locking piece 32 is inserted between the other two limiting pieces 35 to limit the pressure plate 34 again to prevent the plate body 1 from being offset during sanding. When the plate body 1 passes through the other two grinding wheels 39, the grinding wheels 39 sand the other two edges of the plate body 1, and another fan 53 sucks the debris to another debris. In the box cavity 57 of the box 54, when the sheet body 1 moves to the front of the falling mechanism, the piston rod 27 on the cylinder 26 is shortened, driving the pressure plate 34 to move upward, and the pressure plate 34 releases the pressure on the sheet body 1. The top wall of the pressure plate 34 drives the extension bar 48 to move upward, so that the first sliding rack 49 moves upward, and the first sliding rack 49 drives the automatic reset gear 47 to rotate, and the automatic reset gear 47 drives the second sliding rack 51 to move forward, and the second sliding rack 51 pushes the sheet body 1 off. The user can use the storage container to collect the sheet body 1. After the pressure plate 34 is separated from the extension bar 48, the automatic reset gear 47 automatically resets, the second sliding rack 51 moves backward and resets, and the extension bar 48 moves downward and resets.

[0100] When the mass of debris in the box cavity 57 gradually increases, the detection plate 15 gradually overcomes the elastic force of the second elastic member 17 and moves downward, and the wedge block 16 moves downward to drive the wedge rack 18 to overcome the elastic force of the third elastic member 20 and move backward, and the wedge rack 18 extends to the rear of the debris box 54, and the wedge rack 18 engages with the second gear 41. The second gear 41 rotates under the drive of the third rotating rod 40, and the second gear 41 drives the wedge rack 18 and all the debris boxes 54 to move right along the slide rail 55. When the wedge rack 18 and the second gear 41 are disengaged, all the debris boxes 54 continue to move right for a distance under the action of inertia until one of the debris boxes 54 is against the limit plate 56, so that the wedge rack 18 of the next debris box 54 can also engage with the second gear 41. The debris box 54 that is against the limit plate 56 is manually removed to process the debris. The adjacent debris boxes 54 can be detachably connected, for example, by magnetic connection.

[0101] Because the board body 1 (such as particleboard, European pine board, multi-layer board) has many holes, the existing technology mostly uses glue and edge banding strips to seal the edges, which has the disadvantages of easy degumming, unsightly and not moisture-proof in the later stage. However, the present invention uses putty to form a first putty layer 2, a second putty layer 3, a third putty layer 4, and then fills and smoothes the holes on the edge of the board body 1, and cooperates with the paint layer 5, the first color bottom layer 6, the second color bottom layer 7, and the third color bottom layer 8 formed by spraying to prevent the putty layer from falling off and play a waterproof effect. The overall spraying of the topcoat improves the waterproof effect, has a high degree of durability, and has a variety of printed wood grain styles;

[0102] The present invention also uses a sanding machine to sand two opposite edges of the plate body 1, and then use the first gear 36 to cooperate with the steering mechanism to automatically rotate the plate body 1 ninety degrees. The locking plate 32 will also automatically limit and release the limit to facilitate sanding the other two edges of the plate body 1, thereby realizing sanding of the four edges of the plate body 1 without manually rotating the plate body 1. When the pressing state of the plate body 1 is released by the pressing plate 34, the second sliding rack 51 is driven by the power to push down the plate body 1, so as to realize automatic storage of the plate body 1. The debris recovery amount is automatically detected by the detection plate 15. When the preset recovery amount is reached, the debris box 54 is automatically replaced, so that another unloaded debris box 54 is moved to the rear of the fan 53 to prevent the single debris box 54 from collecting too much debris and overflowing when the user does not have time to replace the debris box 54. The design of the sanding machine has high linkage and strong practicality, which can improve the processing efficiency without manual rotation of the plate body 1.
