Technical Field

[0001] The invention relates to the technical field of edge band processing, and in particular to an automatic edge banding machine and a corresponding edge banding method. Background Art

[0002] In the furniture manufacturing process, edge banding of wooden boards is an important process. Edge banding of wooden boards can not only beautify the furniture, but also prevent the wooden boards from bending or deforming due to external forces during use or transportation. However, when edge banding a board with a V-shaped side, it is necessary to first groove the edge banding to facilitate the bending of the edge banding so that it can better fit on the V-shaped side of the board, facilitating the subsequent edge banding bonding process. Existing bevel edge banding cutting equipment needs to readjust the position of the cutting knife each time for edge bands of different thicknesses, resulting in low processing efficiency and poor compatibility. Summary of the invention

[0006] By adopting the above technical solution, the edge band is attached to the reference surface, and the reference surface is set as a curved surface structure, which can make the edge band fit more tightly and improve the accuracy of the groove. The distance between the cutting knife and the reference surface is adjusted based on the remaining uncut thickness of the groove position of the edge band. It is only necessary to adjust the distance between the cutting knife and the reference surface during the first use to adapt to the groove operation of edge bands of different thicknesses, so that the remaining uncut thickness of edge bands of different thicknesses at the groove position is consistent, thereby improving the compatibility of the equipment and the efficiency of the groove.

[0007] Furthermore, the bevel groove device also includes a belt pressing support, a push rod and a pressing block. The belt pressing support is protrudingly arranged at the upper end of the reference seat, the push rod is slidably arranged on the belt pressing support, the pressing block is fixed below the push rod, and the lower surface of the pressing block abuts against the upper side of the edge band, thereby limiting the edge band to be stably attached to the reference surface during groove cutting, so that the grooved positions of the edge band are located on the same horizontal line without any height difference, thereby ensuring the edge banding effect and improving the accuracy and quality of the groove cutting.

The plate and the connecting rod component are connected by a fixing part, and according to the edge bands of different sizes, when adjusting the height of the plate, the fixing part pulls the connecting rod unit to drive the laser component to automatically adjust the height direction, so as to ensure that the laser starting point remains at the center of the edge band. The laser scanning point of the adjusted laser component is located at the center of the edge banding and scans up and down based on the center of the edge banding, which can shorten the scanning stroke of the laser component, shorten the time for heating the dry glue to paste, and make the dry glue on the edge banding more evenly heated during pasting, thereby improving the quality of pasting.

[0012] Furthermore, the connecting rod unit includes a swing arm, a support shaft and a fixed arm. The upper end of the fixed arm is fixedly connected to the laser assembly, and the lower end of the fixed arm is hingedly connected to one end of the swing arm. The other end of the swing arm is fixedly rotatably connected to the other end of the fixing member.

The lower end of the support shaft 5222 is fixed to the second lifting plate 524. The swing arm 5221 swings up and down through the support shaft 5222 to drive the second lifting plate 524, the pull rod 525, and the laser assembly 53 to move up and down, thereby improving the stability during the up and down adjustment process and the verticality of the lifting, thereby ensuring the accuracy of the adjustment. Specifically, two pull rods 525 are provided, and the two pull rods 525 are located between the two guide columns 523. The upper end of the pull rod 525 passes through the mounting plate 511 and is fixed to the lower end of the packaging shell 531 .

[0085] In some embodiments, the lower end of the support shaft 5222 passes through the second lifting plate 524 and is fixedly connected to a limiter 526, which can prevent excessive adjustment from causing damage to parts, extend the service life, and improve safety. Specifically, the limiter 526 includes a limiter block 452 and a limiter wheel.

[0086] In some embodiments, please refer to Fig.15 , a mounting plate 511 is arranged above the base 51. The laser assembly 53 includes a packaging shell 531 and a laser. The laser is used to emit laser light, and the laser is fixed in the packaging shell 531. The side of the packaging shell 531 is provided with a mounting hole 5311 for the laser to pass through. The mounting plate 511 is arranged on the base 51, and the lower end of the packaging shell 531 is connected to the mounting plate 511 by a bearing, so as to facilitate the rotation and adjustment of the angle of the laser emitted by the laser, so that the scanning point of the laser is more closely fitted to the fitting point of the edge band 8 and the plate 9.

[0087] In some embodiments, please refer to Fig.14 , Fig.15 , Fig.16In order to improve the adjustment efficiency and accuracy of the laser angle of the laser, the laser device 5 also includes a rotation adjustment component 54. The rotation adjustment component 54 includes an adjustment rod 541, an adjustment seat 542 and a swing plate 543. The adjustment seat 542 is fixed on the mounting plate 511, the adjustment rod 541 is fixed on the adjustment seat 542, one end of the adjustment rod 541 passes through the adjustment seat 542 and is connected to one end of the swing plate 543, and the other end of the swing plate 543 is fixed to the outside of the packaging shell 531. The adjustment rod 541 is rotated in and out to drive the packaging shell 531 and the laser inside it to rotate, which can improve the efficiency and accuracy of the adjustment.

[0088] The other end of the adjusting rotary rod 541 may be provided with a handle 544 and a locking rod 545. After the handle 544 rotates the adjusting rotary rod 541 to a certain position, the locking rod 545 is locked to prevent the adjusting rotary rod 541 from rotating, thereby improving the stability after adjustment.

[0089] The upper end of the packaging shell 531 is provided with a blowing hole 5312, which is connected to an external blowing device to improve the heat dissipation effect in the packaging shell 531. The blowing device blows gas into the blowing hole 5312, and then flows through the inside of the packaging shell 531 and flows out from the mounting hole 5311 to the outside, which can take out the internal heat and has a good cooling and dust removal effect.

[0090] Firstly, the height of the plate 9 with the edge banding tape is adjusted based on the width of the edge banding tape 8. The rise or fall of the plate 9 drives the rise or fall of the fixing part 521, so that the adjustment height of the laser assembly 53 can be half of the adjustment height of the plate 9, thereby improving the adjustment efficiency, saving costs and occupied space, and making the structure more compact.

[0091] Specifically, when the plate 9 rises, the fixing member 521 rises, and the end of the swing rod connected to the fixing rod 5212 is lifted up. Since the fixing arm 5223 is fixed to the mounting plate 511, the swing arm 5221 drives the support shaft 5222 to move upward, and the support shaft 5222 pulls the second lifting plate 524, the pull rod 525, and the laser assembly 53 to rise synchronously. When the plate 9 falls, the fixing member 521 falls, and the end of the swing rod connected to the fixing rod 5212 moves downward. Since the fixing arm 5223 is fixed to the mounting plate 511, the swing arm 5221 presses the support shaft 5222 to move downward, and the support shaft 5222 pulls the second lifting plate 524, the pull rod 525, and the laser assembly 53 to fall synchronously.

[0092] Secondly, the scanning point position of the laser is manually adjusted based on the bonding point position of the plate 9 and the edge band 8, so that the scanning point of the laser is closer to the bonding point.

[0093] Specifically, the adjustment rod 541 is rotated according to the position of the current scanning point. The rotation of the adjustment rod 541 can push the swing plate 543 to rotate clockwise or counterclockwise, thereby driving the packaging shell 531 and the laser thereon to rotate around the bearing connected to the mounting plate 511, so that the scanning point of the adjusted laser is located at the fitting point between the plate 9 and the edge band 8. The scanning point of the laser heats and melts the soft glue coated on the edge band 8, and then it is promptly applied to the plate 9 to improve the quality of the adhesion.

[0094] An edge banding method of an automatic edge banding machine 1, please refer to Fig.17 , using any of the above-mentioned automatic edge banding machines 1 to attach the edge banding tape 8 to the board 9, which includes:

[0095] Step S1, adjusting the height of the plate 9 and the laser irradiation angle of the laser device 5 based on the width of the edge band 8, so that the laser scanning point is located at the bonding point of the plate 9 and the edge band 8; adjusting the height of the cutting knife 62 in the bevel grooving device 6 based on the grooving position of the edge band 8; adjusting the pressing and cutting device 4 to press the edge band 8 during the conveying process;

[0096] Step S2, the conveying component 42 in the pressing and cutting device 4 pulls the edge band 8 to be conveyed toward the plate 9, and the edge pressing component of the pressing and cutting device 4 is adjusted to press and fix the edge band 8;

[0097] Step S3, during the conveying process, the cutting knife 62 of the bevel slotting device 6 rotates to slot the edge band 8; the distance between the cutting knife 62 and the reference surface 611 of the reference seat is fixed so that the thickness of the uncut portion of the slotted edge band 8 is the same;

[0098] Step S4, the scanning point of the laser of the laser assembly takes the center of the edge band 8 as the starting point and scans up and down to heat the dry glue at the bonding part of the packaging band;

[0099] Step S5, the pressing device 3 presses and adheres the edge banding 8 with melted dry glue onto the plate 9; when the conveying length of the edge banding 8 meets the edge banding length, the cutting component 44 of the pressing and cutting device 4 cuts the edge banding 8 to complete the edge banding operation.

[0100] Among them, the position of the laser device 5 can automatically adjust its height according to the edge banding 8 of different widths, so that the scanning point of the laser of the laser device 5 always takes the center of the edge banding 8 as the starting point, ensuring that the dry glue on the adhesive surface of the edge banding 8 is heated more evenly, ensuring the melting degree of the dry glue on the upper and lower sides of the edge banding 8, so that the bonding effect is better. The bevel grooving device 6 can perform grooving operations on the edge banding 8, and the cutting knife 62 only adjusts the distance between it and the reference surface 611 when used for the first time, which can adapt to edge bands 8 of different thicknesses and has stronger compatibility. The pressure-feeding and cutting-off device 4 can synchronously lift and lower multiple pressing points to press and fix the edge banding 8, prevent the edge banding 8 from warping, bending, etc. during transportation, and improve the efficiency of board pasting.

[0101] In some embodiments, step S1 specifically includes:

[0102] Step S11, the conveying frame 2 for conveying the plate 9 raises or lowers the plate 9 to a set height according to the width of the edge band 8. One end of the fixing part 521 of the laser device 5 is fixed on the plate 9 frame and rises or falls with the plate 9, and is automatically adjusted, which is more efficient. The adjustment of the fixing part 521 drives the connecting rod assembly and the laser assembly 53 thereon to adjust the height. Under the action of the connecting rod assembly, the height adjusted by the laser assembly 53 is half of the height adjusted by the plate 9, which has a compact structure and saves space. Based on the rotation adjustment assembly 54, the laser assembly 53 is manually rotated so that the scanning point of the laser is located at the joint of the plate 9 and the edge band 8, so that the dry glue at the joint is collected more evenly, thereby improving the quality of the joint.

[0103] Step S12, according to the slotting position of the edge banding 8, manually adjust the horizontal adjustment screw 642 to drive the lifting seat 643 and the cutting motor 63 and the cutting knife 62 thereon to perform synchronous lifting and lowering movements, so that the cutting knife 62 is located in the slot position of the edge banding 8, lock the horizontal adjustment screw 642, and the cutting knife 62 can be adjusted in height according to the actual required slotting height, which is easy to operate and has stronger compatibility.

[0104] Step S13, rotating the first screw rod 4333 drives the second screw rod 4335 to pull the second lifting plate 524, the two first pressing rods 431, and the second pressing rod 434 thereon downward, so that the first pressing rod 431 and the second pressing rod 434 press the edge band 8 onto the conveying platform 41, and synchronously adjusting, which is more efficient and improves the overall pressing accuracy. Moreover, the up and down adjustment method has a more compact structure, reduces the occupied space, and saves costs.

[0105] In step S2 , the conveying assembly 42 in the pressing and cutting device 4 pulls the edge band 8 to be conveyed toward the plate 9 , and the edge pressing assembly of the pressing and cutting device 4 is adjusted to press and fix the edge band 8 .

[0106] This step is described in detail below.

[0107] The handle 4332 is manually rotated forward and backward, and the handle 4332 drives the first screw rod 4333 to rotate, and the horizontal force is converted into a vertical force through the steering gear 4334 to drive the second screw rod 4335 to rotate. The forward and reverse rotation of the second screw rod 4335 drives the second lifting plate 524 and the multiple first pressure rods 431 and second pressure rods 434 thereon to rise and fall synchronously along the length direction of the guide rod, so that the pressing piece 4342 and the pressing shaft 4312 are pressed tightly against the upper side of the edge band 8. The cylinder 428 drives the connecting block 4343 and the conveying wheel 425 to rotate around the center of the output shaft of the conveying motor 421 to be close to the edge band 8, so that the edge band 8 and the conveying wheel 425 fit more closely, improving the transmission of the force and the stability of the conveying of the edge band 8. Then, under the driving force of the conveying motor 421, the first gear 422 drives the second gear 423 to rotate, and the second gear 423 drives the conveying wheel 425 to rotate. The friction between the conveying wheel 425 and the side of the edge band 8 drives the edge band 8 to move along the conveying direction.

[0108] In step S3, during the conveying process, the cutting blade 62 of the bevel slotting device 6 rotates to slot the edge band 8. The distance between the cutting blade 62 and the reference surface 611 of the reference seat is fixed so that the thickness of the uncut portion of the edge band 8 at the slot is the same.

[0109] This step is described in detail below.

[0110] The user can adjust the position of the cutting knife 62 by turning the horizontal adjustment screw 642 or the lifting screw 641 through the tool locking adjustment joint 647. Rotating the horizontal adjustment screw 642 can drive the cutting motor 63 to move horizontally to adjust the distance between the cutter head of the cutting knife 62 and the reference surface 611. Through multiple slotting tests, the remaining uncut thickness is detected to determine whether the cutting knife 62 is adjusted in place. Then, by closing the locking valve 648 on the horizontal adjustment screw 642, the horizontal adjustment screw 642 is fixed to fix the horizontal position of the cutting knife 62.

[0111] The user can use a tool to lock the adjustment joint 647 on the lifting screw 641 to rotate forward and reverse to drive the horizontal adjustment screw 642, the lifting seat 643, the cutting motor 63, and the cutting knife 62 to move up and down along the lifting screw 641 synchronously, thereby adjusting the height of the cutting knife 62. When the height is adjusted to a suitable height, the locking valve 648 on the lifting screw 641 is closed to fix the lifting screw 641, thereby locking the position of the cutting knife 62.

[0112] After the position of the cutting blade 62 is adjusted, the cutting motor 63 is started to drive the cutting blade 62 to rotate, and the cutting blade 62 performs a slotting operation on the edge banding 8 attached to the reference seat 61. The edge banding 8 is transported toward the plate 9 under the traction of the transport wheel 425 while being cut.

[0113] In step S4, the scanning point of the laser of the laser assembly scans up and down with the center of the edge band 8 as the starting point to heat the dry glue at the bonding part of the packaging band.

[0114] This step is described in detail below.

[0115] First, when the plate 9 rises, the fixing member 521 rises, and the end of the swing rod connected to the fixing rod 5212 is lifted up. Since the fixing arm 5223 is fixed on the mounting plate 511, the swing arm 5221 drives the support shaft 5222 to move upward, and the support shaft 5222 pulls the second lifting plate 524, the pull rod 525, and the laser assembly 53 to rise synchronously. When the plate 9 falls, the fixing member 521 falls, and the end of the swing rod connected to the fixing rod 5212 moves downward. Since the fixing arm 5223 is fixed on the mounting plate 511, the swing arm 5221 presses the support shaft 5222 to move downward, and the support shaft 5222 pulls the second lifting plate 524, the pull rod 525, and the laser assembly 53 to fall synchronously. The support shaft 5222 is set at the center position of the swing arm 5221, so that the adjustment height of the laser assembly 53 can be half of the adjustment height of the plate 9, thereby improving the adjustment efficiency, saving costs and occupied space, and having a more compact structure.

[0116] Secondly, the adjustment rod 541 is rotated according to the position of the current scanning point. The rotation of the adjustment rod 541 can push the swing plate 543 to rotate clockwise or counterclockwise, thereby driving the packaging shell 531 and the laser thereon to rotate around the bearing connected to the mounting plate 511, so that the scanning point of the adjusted laser is located at the fitting point between the plate 9 and the edge band 8. The scanning point of the laser heats and melts the soft glue coated on the edge band 8, and then it is promptly applied to the plate 9 to improve the quality of the adhesion.

[0117] In step S5, the pressing device 3 presses the edge banding 8 with the glue just melted at the laminating point onto the board 9. When the edge banding of the board 9 is almost finished, the cutter 441 of the cutting assembly 44 of the pressing and cutting device 4 cuts the edge banding 8 according to the set length of the edge banding 8, the conveying motor 421 stops working, and the pressing device 3 sticks the remaining edge banding 8 onto the board 9 to complete the edge banding operation.

[0118] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
