[0056] The preferred embodiments of the present invention will be described in detail below.

[0057] As shown in the attached drawings, it is a schematic diagram of the present invention. It is used to attach an edge banding strip to the side edge of a board, then cut off the excess edge banding strip, and finally polish the edge of the board. It includes a conveying structure 1, an edge banding structure 2, a trimming structure 3, and a polishing structure 4. As Figures 1-3 shown, it is a schematic diagram of the structure of the conveying structure 1. It is used to convey the board to be edge banded, and includes a conveying bottom plate 11, a lower conveyor belt 12, a conveying top plate 13, an upper conveyor belt 14, a backing plate 15, a positioning post 16, and a trailing wheel 17. The conveying bottom plate 11 is fixed to the workshop machine table by means of bolts. The conveying top plate 13 is fixed above the conveying bottom plate 11 by aluminum profiles. There is a gap between the conveying top plate 13 and the conveying bottom plate 11 for conveying the board to be edge banded.

[0058] Grooves are provided on the opposite sides of the conveying bottom plate 11 and the conveying top plate 13. The lower conveyor belt 12 and the upper conveyor belt 14 are respectively rotatably installed in the grooves. The board to be edge banded is placed between the upper conveyor belt 14 and the lower conveyor belt 12 (a rotating shaft is installed in the groove, and the lower conveyor belt 12 is wound around the rotating shaft and driven by a motor on one side to drive the rotating shaft to rotate, thereby driving the lower conveyor belt 12 to rotate synchronously. The upper conveyor belt 14 is installed in the same way as the lower conveyor belt 12. The materials of the upper conveyor belt 14 and the lower conveyor belt 12 are rubber to avoid scratching the surface of the board). The backing plate 15 is fixed to the conveying bottom plate 11, and the fixing direction of the backing plate 15 is the same as the conveying direction of the board. By providing the backing plate 15 on the conveying bottom plate 11, the board placed on the conveying bottom plate 11 is positioned. During actual edge banding, the side of the board to be edge banded is leaned against the backing plate 15 and pushed forward between the upper conveyor belt 14 and the lower conveyor belt 12.

[0059] The positioning post 16 is provided on the conveying bottom plate 11 and is located at the front end of the lower conveyor belt 12. The positioning post 16 is driven by a cylinder to lift and lower. When the previous board is pushed onto the lower conveyor belt 12, the positioning post 16 rises to block the next board. After the previous board is edge banded, the positioning post 16 descends to be flush with the conveying bottom plate 11, and the operator continues to place a new board. A trailing wheel bracket is fixed to one side of the conveying bottom plate 11. Multiple groups of trailing wheels 17 are installed on the trailing wheel bracket through rotating shafts. The other side of the board placed on the conveying bottom plate 11 abuts against the trailing wheels 17. With the auxiliary support of the trailing wheels 17, the movement of the board is facilitated.

[0060] As Figures 4-7As shown in the figure, the edge banding structure 2 is fixed on the conveying bottom plate 11 and is used for edge banding the side edges of the board. It includes a guiding component 21, a cutting component 23, and a glue injection component 24. The guiding component 21 is fixed on the top of the conveying bottom plate 11 and is used for unrolling and guiding the edge banding strip. It includes a baffle 211, a height adjustment groove 212, a rotating column 213, a retaining piece 214, an arc portion 215, a fixing column 216, a height adjustment block 217, a locking bolt 218, a height adjustment rod 219, a first vertical plate 220, a groove 221, an induction column 222, a driving cylinder 223, and a driven cylinder 224. The baffle 211 is vertically fixed on the top of the conveying bottom plate 11. The height adjustment groove 212 is vertically opened on the baffle 211. The height adjustment groove 212 is used for limiting the height adjustment rod 219 to ensure that the edge banding strip below does not move up and down during conveying. The rotating column 213 is rotatably installed on the top of the conveying bottom plate 11 and is located on one side of the baffle 211 (the rotating column 213 rotates passively rather than actively. There is a through hole on one side of the conveying bottom plate 11 close to the baffle 211. A bearing is installed in the through hole, and the central rotating shaft is fixed to the inner ring of the bearing. Therefore, under the action of the bearing, the central rotating shaft will rotate freely, and the rotating column 213 is sleeved on the central rotating shaft and fixed to the central rotating shaft. Therefore, the rotating column 213 can rotate freely under the action of the bearing).

[0061] The retaining piece 214 is integrally connected to one side of the rotating column 213 and moves synchronously with the rotating column 213. The retaining piece 214 is provided with an arc portion 215 on the side close to the baffle 211. As Figure 7 shown, one side of the unrolled edge banding strip abuts against the baffle 211, and the other side is pressed by the arc portion 215 of the retaining piece 214. When the edge banding strip moves forward, the pre-pressure of the retaining piece 214 is used to prevent the edge banding strip from spreading horizontally. Since the retaining piece 214 is connected to the rotating column 213, when facing edge banding strips of different thicknesses, the retaining piece 214 can still play a pre-pressure role, improving the versatility.

[0062] The fixing column 216 is fixed on the top of the conveying bottom plate 11 and is located on one side of the baffle 211. The height adjustment block 217 is sleeved on the fixing column 216 and can be adjusted up and down within the fixing column 216. A through hole is opened in the middle of the height adjustment block 217. The through hole is sleeved on the fixing column 216, and the position of the height adjustment block 217 can be adjusted up and down along the fixing column 216. The locking bolt 218 passes through the height adjustment block 217 and is screwed onto the fixing column 216. When the position of the height adjustment block 217 needs to be adjusted, first loosen the locking bolt 218, adjust it to an appropriate height, and then tighten the locking bolt 218. The height adjustment rod 219 is integrally connected to one side of the height adjustment block 217 and moves synchronously with the height adjustment block 217. The height adjustment rod 219 is sleeved in the height adjustment groove 212. The height adjustment rod 219 is used for limiting the height of the edge banding strip conveyed below to prevent the edge banding strip from moving up and down during conveying and affecting the edge banding effect.

[0063] The first vertical plate 220 is vertically fixed on the conveying bottom plate 11 and is located on one side of the baffle 211. A groove 221 is opened at the bottom of the first vertical plate 220. The sensing column 222 is rotatably installed in the groove 221 (the sensing column 222 is driven to rotate passively rather than actively. A rotating shaft is vertically arranged in the groove 221, and both sides of the rotating shaft are connected to the conveying bottom plate 11 and the first vertical plate 220 through bearings. The sensing column 222 is sleeved on the rotating shaft and fixed to the rotating shaft. The inner side of the edge banding strip after unwinding abuts against the sensing column 222. When the outer plate is conveyed to the sensing column 222, it contacts the sensing column 222 and drives the sensing column 222 to rotate by relying on the frictional force, thereby squeezing the edge banding strip against the side edge of the plate and then driving the edge banding strip to move forward). The driving cylinder 223 is rotatably installed on the conveying bottom plate 11 and is located on one side of the first vertical plate 220. The driven cylinder 224 is rotatably installed on the conveying bottom plate 11 and is located on one side of the driving cylinder 223. A motor is installed at the bottom of the driving cylinder 223 to drive the driving cylinder 223 to rotate. The fixing method of the driven cylinder 224 is the same as that of the rotating column 213 and is connected to the conveying bottom plate 11 by relying on bearings. By providing the driving cylinder 223 and the driven cylinder 224, it is used to extrude the plate after edge banding to ensure that the edge banding is more firm.

[0064] The cutting component 23 is fixed on the conveying bottom plate 11 and is located between the first vertical plate 220 and the driving cylinder 223 and is used to cut the edge banding strip. It includes a second vertical plate 231, a cylinder fixing plate 232, a moving cylinder 233, a cutting plate 234, a cutting edge 235, a guiding plate 236 and a guiding groove 237. The second vertical plate 231 is fixed on the top of the conveying bottom plate 11 and is parallel to the first vertical plate 220. The cylinder fixing plate 232 is fixed on one side of the second vertical plate 231. The cylinder body of the moving cylinder 233 is fixed on the cylinder fixing plate 232. The guiding rod of the moving cylinder 233 passes through the cylinder fixing plate 232 and is connected to the cutting plate 234 to drive the cutting plate 234 to move. The cutting edge 235 is integrally connected to one side of the cutting plate 234 and cuts the edge banding strip under the drive of the moving cylinder 233. The guiding plates 236 are fixedly spaced in the vertical direction on the side surface of the second vertical plate 231. The guiding grooves 237 are opened on the facing sides of the guiding plates 236. The cutting plate 234 is arranged in the guiding grooves 237. Under the guiding action of the guiding grooves 237, it is ensured that the movement of the cutting plate 234 is more stable.

[0065] The glue injection component 24 is fixed on the top of the conveying bottom plate 11 and is located on one side of the guiding component 21 and is used to apply glue to the side edge of the plate to facilitate subsequent pasting of the edge banding strip, such as Figures 8-10As shown in the figure, it includes a glue injection bottom plate 241, a glue injection plate 242, a glue inlet 243, a glue return port 244, a threaded hole 245, an adhesive mixing column 246, a glue channel 247 and a glue column 248. The glue injection bottom plate 241 is fixed on the top of the conveying bottom plate 11, and the glue injection plate 242 is vertically fixed on the top of the glue injection bottom plate 241. The glue channel 247 is opened on one side of the glue injection plate 242, and the glue channel 247 is arc-shaped. The glue inlet 243 is horizontally opened on the glue injection plate 242 and is connected to the glue channel 247. The glue inlet 243 is externally connected to a glue water tank, and glue is injected through the glue inlet 243 and flows into the glue channel 247. The glue column 248 is rotatably installed in the glue channel 247, and the glue column 248 is driven to rotate by a motor. After the glue is injected through the glue inlet 243 and flows into the glue channel 247, it will adhere to the surface of the glue column 248 as the glue column 248 rotates. The glue return port 244 is opened on the glue injection bottom plate 241 and is located at the bottom of the glue channel 247. The excess glue on the glue column 248 will flow back into the glue water tank through the glue return port 244. The threaded hole 245 is opened on the glue injection plate 242 and is communicated with the glue inlet 243. The adhesive mixing column 246 is screwed into the threaded hole 245. By screwing the adhesive mixing column 246, the size of the glue inlet 243 is changed, so as to control the amount of glue.

[0066] Edge sealing principle of the edge sealing structure 2: After the edge sealing strip is unrolled, it leans between the baffle 211 and the retaining piece 214. When the conveyed plate passes through the glue injection assembly 24, the glue column 248 applies glue to the side of the plate. When the plate is conveyed forward and touches the edge sealing strip, under the rotation of the induction column 222, the edge sealing strip is pulled and pasted on the side of the plate. The cutting plate 234 is driven by the moving cylinder 233 to cut off the edge sealing strip, and finally the plate and the edge sealing strip are pressed tightly by the driving cylinder 223 and the driven cylinder 224.

[0067] As Figures 11-15 As shown in the figure, it is a schematic structural diagram of the edge trimming structure 3, which is usually used to trim the excess edge sealing strips on both sides of the plate. It includes a blanking groove 301, a support table 302, an inclined surface 303, a slide rail 304, a slider 305, a slide plate 306, a fixed block 307, a telescopic cylinder 308, a synchronous plate 309, a drag chain 310, a first connecting plate 311, a second connecting plate 312, a second moving cylinder 313, a leveling block 314, a backing plate 315, a first motor 316, a rotating piece 317, a cutting edge 318, a protective sleeve 319, a blade groove 320 and an oil buffer 321.

[0068] The blanking chute 301 is opened on the conveying bottom plate 11. The blanking chute 301 is used to drop the cut edge bands, preventing the cut edge bands from accumulating on the conveying bottom plate 11. A storage box is placed below the blanking chute 301 for collecting the cut edge bands. The support platform 302 is fixed on the top of the conveying bottom plate 11, and the bottom of the support platform 302 is connected to the blanking chute 301. The support platform 302 is in the shape of an isosceles right triangle. One right side of the support platform 302 is fixed to the conveying bottom plate 11. The inclined hypotenuse of the support platform 302 is a 45° inclined plane 303. The cutting structure is fixed on the inclined plane 303. By setting the inclined inclined plane 303, it can ensure that while the board is being conveyed, the vertical cutting of the edge bands on both sides is completed, improving the cutting efficiency. The cut edge bands then fall into the storage box below along the blanking chute 301.

[0069] The slide rail 304 is fixed on the inclined plane 303 by means of screw fastening. The fixing direction of the slide rail 304 is parallel to the inclined direction of the inclined plane 303. The slider 305 is slidably installed on the slide rail 304. The sliding plate 306 is fixed on the slider 305. Relying on the sliding action of the slider 305, the sliding plate 306 slides along the inclined plane 303 of the support platform 302. By setting the slider 305 and the slide rail 304, it ensures that the sliding plate 306 slides more smoothly. The fixing blocks 307 are fixedly spaced on the inclined plane 303. The cylinder body of the telescopic cylinder 308 is fixed on the fixing block 307. The guide rod of the telescopic cylinder 308 is connected to the sliding plate 306 through the synchronous plate 309. When the telescopic cylinder 308 moves, it drives the sliding plate 306 to move synchronously through the synchronous plate 309. The oil buffer 321 is fixed at the bottom of the inclined plane 303 and is used in cooperation with the synchronous plate 309. When the sliding plate 306 moves to the lowest position, the synchronous plate 309 will contact the oil buffer 321, and by squeezing the oil buffer 321, the overall vibration is reduced.

[0070] The drag chain 310 is fixed on one side of the support platform 302. The material of the drag chain 310 is rubber. The drag chain 310 is used to place the air pipes and electric wires connected to the telescopic cylinder 308, etc., to prevent the wires from being arranged in a messy manner and causing a short - circuit phenomenon. The first connecting plate 311 is fixed on the top of the sliding plate 306. One end of the second connecting plate 312 is fixed to the first connecting plate 311, and the other end is connected to the drag chain 310. When the telescopic cylinder 308 drives the sliding plate 306 to move, the sliding plate 306 drives the drag chain 310 to move through the first connecting plate 311 and the second connecting plate 312 (the first connecting plate 311 and the second connecting plate 312 form an "L" shape. When the sliding plate 306 drives the drag chain 310 to move, it avoids interference with the telescopic cylinder 308).

[0071] The second moving cylinder 313 is fixed to the top of the sliding plate 306, and the leveling block 314 is fixed to the second moving cylinder 313. Driven by the second moving cylinder 313, the leveling block 314 moves on the sliding plate 306. The moving direction of the leveling block 314 is parallel to the conveying bottom plate 11 and moves toward the side close to or away from the telescopic cylinder 308 (the cross-section of the leveling block 314 is an isosceles right triangle, and the hypotenuse of the leveling block 314 is fixed to the second moving cylinder 313, so the upper surface of the leveling block 314 is parallel to the conveying bottom plate 11). The backing plate 315 is fixed to the top of the leveling block 314 and moves synchronously with the leveling block 314.

[0072] The first motor 316 is fixed to the backing plate 315, and the rotating plate 317 is connected to the output shaft of the first motor 316. Driven by the first motor 316, the rotating plate 317 rotates. The cutting edges 318 are circumferentially arranged on the outer peripheral surface of the rotating plate 317. Under the rotation of the rotating plate 317, the cutting of the edge of the plate is completed. Since both the support table 302 and the leveling block 314 are in the shape of an isosceles right triangle, the movement of the rotating plate 317 is synchronous with that of the plate. The protective cover 319 is fixed to one side of the backing plate 315 and sleeved on the rotating plate 317. The blade groove 320 is opened on the protective cover 319. The width of the blade groove 320 is greater than the thickness of the rotating plate 317 to prevent interference between the rotating plate 317 and the protective cover 319 during rotation. The protective cover 319 is used to protect the surrounding construction workers from accidentally touching the rotating plate 317 with their hands.

[0073] Edge trimming principle of the edge trimming structure 3: The plate after edge sealing is conveyed between the lower conveyor belt 12 and the upper conveyor belt 14. When it is conveyed to the edge trimming structure 3, the telescopic cylinder 308 drives the sliding plate 306 to move along the inclined surface 303. At this time, the rotating rotating plate 317 moves synchronously. Since both the support table 302 and the leveling block 314 are in the shape of an isosceles right triangle, the position of the rotating plate 317 relative to the front edge seal of the plate remains unchanged. During the movement of the sliding plate 306, the front edge seal of the plate is cut off. After cutting off, to avoid interference with the subsequent plates, the second moving cylinder 313 drives the backing plate 315 to move outward, first away from the conveyor platform, and then the telescopic cylinder 308 resets (two groups of cutting structures are installed at intervals on one side of the conveyor platform, respectively used for cutting the front and rear edge seals of the plate).

[0074] As Figures 16-21As shown in the figure, it is a schematic structural diagram of the polishing structure 4, which is used to polish the sheet after trimming the edges. It includes guide posts 401, a top plate 402, a fixed plate 403, a lifting plate 404, a fixed groove 405, a lifting groove 406, sliding columns 407, a sliding plate 408, sliding blocks 409, a moving plate 410, a second motor 411, an upper shield 412, a lower shield 413, upper chip removal holes 414, lower chip removal holes 415, upper polishing discs, lower polishing discs, side plates 422, bumps 423, screw grooves 424, screws 425, fastening nuts 426 and clamping blocks 427. There are two guide posts 401, which are fixedly spaced at the top of the conveying bottom plate 11 by welding, and the top plate 402 is fixed at the top of the two guide posts 401. Both the fixed plate 403 and the lifting plate 404 pass through the guide posts 401, and the fixed plate 403 is fixed to the conveying bottom plate 11, while the lifting plate 404 is arranged above the fixed plate 403 with adjustable height. By adjusting the distance between the lifting plate 404 and the fixed plate 403, the polishing requirements for sheets of different thicknesses can be met. A fixed groove 405 is opened on one side of the fixed plate 403, and a lifting groove 406 is opened on one side of the lifting plate 404. The opening directions of the fixed groove 405 and the lifting groove 406 are the same.

[0075] The side plates 422 are fixed to one side of the top plate 402 by welding, and the bumps 423 are fixed to one side of the lifting plate 404 by welding (the bumps 423 are located on the side of the lifting plate 404 away from the lifting groove 406, and the side plates 422 are located directly above the bumps 423). The screw groove 424 vertically penetrates the side plates 422, the screw 425 is inserted into the screw groove 424 and the bottom of the screw 425 passes through the bump 423. The top of the screw 425 is integrally connected with a clamping block 427. The diameter of the clamping block 427 is larger than the diameter of the screw 425. Therefore, under the action of the clamping block 427, the screw 425 will not fall out of the screw groove 424. The fastening nut 426 is screwed onto the bottom of the screw 425, and the upper surface of the fastening nut 426 abuts against the lower surface of the bump 423 (in actual situations, when it is necessary to adjust the height of the lifting plate 404, the fastening nut 426 can be rotated. Since the top of the screw 425 is clamped by the clamping block 427, with the screwing of the fastening nut 426, the bump 423 will be gradually driven to move up and down along the screw 425, so the lifting plate 404 moves up and down synchronously to meet the polishing requirements for sheets of different thicknesses).

[0076] The slide post 407 passes through the lifting groove 406 and the fixed groove 405 and can move horizontally along the fixed plate 403 and the lifting plate 404. A slide plate 408 is fixed to the other side of the slide post 407. By providing the slide plate 408, it is ensured that the slide post 407 can move synchronously (a rodless cylinder is fixed to the other side of the slide plate 408, which drives the slide plate 408 to move under the drive of the rodless cylinder, and then drives the slide post 407 to move synchronously. The rodless cylinder is not shown in the figure). The sliding block 409 is sleeved on the slide post 407 and fixed to the slide post 407. Therefore, under the drive of the rodless cylinder, the sliding block 409 moves synchronously with the slide post 407 (in this embodiment, the length of the sliding block 409 is less than the lengths of the fixed groove 405 and the lifting groove 406, ensuring that the sliding block 409 has space for horizontal movement in the lifting groove 406 and the fixed groove 405, and thus realizing the grinding work on the edge of the plate). The moving plate 410 is fixed to the sliding block 409 and moves synchronously with the sliding block 409.

[0077] There are two groups of second motors 411, which are respectively fixed to the side of the moving plate 410 away from the sliding block 409. The upper grinding disc and the lower grinding disc are fixed to the side of the second motor 411. Driven by the second motor 411, the upper grinding disc and the lower grinding disc rotate to realize the grinding work on the edge of the plate.

[0078] The upper grinding disc includes an upper shield 412, upper chip discharge holes 414, an upper inner grinding disc 416, an upper outer grinding disc 417 and an upper grinding angle 418. The upper shield 412 is semi-circular and fixed to the casing of the second motor 411 (in this embodiment, the opening of the upper shield 412 faces downward, which is used to block the upper inner grinding disc 416 and the upper outer grinding disc 417 to prevent the operator from accidentally touching the grinding disc by hand). The upper chip discharge holes 414 are opened on the circumferential surface of the upper shield 412, and the chips generated by the grinding of the upper inner grinding disc 416 and the upper outer grinding disc 417 are discharged from the upper chip discharge holes 414. The upper inner grinding disc 416 is fixed to the motor shaft of the second motor 411, the upper outer grinding disc 417 is integrally connected to the outside of the upper inner grinding disc 416, and the diameter of the upper inner grinding disc 416 is larger than that of the upper outer grinding disc 417. The upper grinding angle 418 is arranged between the upper inner grinding disc 416 and the upper outer grinding disc 417 and is used to grind the corners of the plate. The upper inner grinding disc 416 and the upper outer grinding disc 417 are made of cotton yarn to avoid damaging the plate while grinding.

[0079] The lower grinding disc includes a lower shield 413, a lower chip discharge hole 415, a lower inner grinding disc 419, a lower outer grinding disc 420, and a lower grinding corner 421. The lower shield 413 is semi-circular and fixed to the housing of the second motor 411 (in this embodiment, the opening of the lower shield 413 faces upward, used to block the lower inner grinding disc 419 and the lower outer grinding disc 420 to prevent the operator from accidentally touching the grinding disc by hand). The lower chip discharge hole 415 is opened on the circumferential surface of the lower shield 413, and the debris generated by the grinding of the lower inner grinding disc 419 and the lower outer grinding disc 420 is discharged from the lower chip discharge hole 415. The lower inner grinding disc 419 is fixed to the motor shaft of the second motor 411, the lower outer grinding disc 420 is integrally connected to the outside of the lower inner grinding disc 419, and the diameter of the lower inner grinding disc 419 is larger than the diameter of the lower outer grinding disc 420. The lower grinding corner 421 is arranged between the lower inner grinding disc 419 and the lower outer grinding disc 420 and is used to grind the corners of the plate. The materials of the lower inner grinding disc 419 and the lower outer grinding disc 420 are cotton yarn, which can avoid damaging the plate while grinding.

[0080] The polishing principle of the polishing structure 4: First, appropriately adjust the height of the lifting plate 404 according to the thickness of the plate to be polished, start the second motor 411, the second motor 411 drives the upper grinding disc and the lower grinding disc to rotate, and the rodless cylinder drives the upper grinding disc and the lower grinding disc to reciprocate horizontally. During the movement, the plate on the other side is polished.
