Description

Technical Field

[0001] The invention relates to the technical field of auxiliary feeding of edge banding machines, in particular to automatic feeding and conveying equipment for a bevel edge banding machine. Background Art

[0002] Edge banding machines are mainly used for edge banding of wooden furniture boards. They are mainly used to reduce the roughness of the side of the board and improve the aesthetics of the board.

[0003] At present, the edge banding machine needs to rely on the coordinated operation of multiple devices for the side edge banding operation of the board. The feeding equipment includes the feeding equipment for the wooden board, the feeding equipment for the sealing tape and the feeding equipment for the glue liquid, etc. The sealing tape link is arranged after the gluing link, but in this process, the specifications of the sealing tape are constant while the thickness of the wooden board is different. When the sealing tape is pressed and pasted on the side of the wooden board, the glue squeezed by the sealing tape will overflow to the top and bottom of the wooden board, and the curing speed of the sealing tape and the wooden board is affected by the ambient temperature. Once the above phenomenon occurs, the subsequently cured glue will cause color difference on the surface of the wooden board. At the same time, after the sealing tape that is too long is cut and subjected to excessive pressure, the sealing tape on the side of the wooden board will become loose.

[0060] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0061] An automatic feeding and conveying device for a bevel edge banding machine provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0062] Embodiment 1:

[0063] Combination Figure 1-Figure 10As shown, the present invention provides an automatic feeding and conveying device for a bevel edge banding machine, comprising a wooden board 100, an edge banding 200 and two beams 300, a tape unwinding mechanism 500 arranged on one of the beams 300, a tape leading mechanism 600 arranged on the other beam 300, a distance control component 400 arranged in the tape unwinding mechanism 500 and the tape leading mechanism 600, a gradual temperature control and pressing mechanism 700 arranged on the tape leading mechanism 600, and an edge banding cutting and gluing mechanism 800 arranged on the tape leading mechanism 600. The wooden board 100 is arranged in a board feeder. The edge banding 200 is used to load the material in accordance with the moving direction of the wooden board 100, and to perform edge banding on the side of the wooden board 100. The two cross beams 300 are used to provide a uniform height of support force for the unwinding mechanism 500 and the leading mechanism 600. The distance control component 400 is used to adjust the distance between the unwinding mechanism 500 and the leading mechanism 600, and to adjust the tensioning force of the loading edge banding 200. The unwinding mechanism 500 is used to actively release the edge banding 200, and the leading mechanism 600 is used to adjust the feeding angle of the edge banding 200 until the edge banding 200 is adapted to the side of the wooden board 100.

[0064] The distance control assembly 400 includes a track plate 410, and evenly distributed vertical holes are opened inside the track plate 410;

[0065] Four latches 420 are disposed inside the track plate 410;

[0066] The tape unwinding mechanism 500 includes a first base 510 and a second base 520 , and a fixed pressure wheel 530 is disposed on the top of the first base 510 ;

[0067] The first clamping seat 570 is installed on the first base 510 and the second base 520, and the first screw sleeve 580 is movably installed in the two first clamping seats 570, and the first progressive screw rod 590 and the first core rod 550 are arranged inside the first base 510 and the second base 520;

[0068] The first screw sleeve 580 is movably mounted on the first progressive screw rod 590 , a first spring 560 is disposed outside the first core rod 550 , and a first tensioning member 540 is disposed between adjacent ends of the first progressive screw rod 590 and the first core rod 550 ;

[0069] The guide mechanism 600 includes a third base 610 and a fourth base 620, a second progressive screw rod 690 and a second core rod 650 arranged in the third base 610 and the fourth base 620, two second clamping seats 670 arranged on the third base 610 and the fourth base 620, a second screw sleeve 680 movably installed in the two second clamping seats 670, and the second screw sleeve 680 is movably installed on the second progressive screw rod 690;

[0070] A second spring 660 is disposed outside the second core rod 650, and a second tensioning member 640 is disposed between the second progressive screw rod 690 and the adjacent ends of the second core rod 650;

[0071] The gradual temperature control and pressing mechanism 700 includes three pressure-boosting rollers 770 , in which a return pipe 780 is arranged, and a water pipe 790 is installed on the return pipe 780 ;

[0072] The edge banding, cutting and gluing mechanism 800 includes a truss 810, two board guides 840 adapted to the end surfaces of the wooden board 100, two scrapers 870 arranged in the two board guides 840, and a chassis 850 arranged on the board guides 840, and the chassis 850 is used to provide heat for the scrapers 870, and an auxiliary cutting component 880 is arranged on the board guide 840. A chuck 820 is installed at the outer end of the truss 810, a reset component 830 is arranged in the chuck 820, and the two board guides 840 are respectively arranged at the top and bottom of the reset component 830, and a wire 860 is connected to the street of the chassis 850.

[0073] During the use of the edge banding machine, the wood board needs to be actively transported by the conveying equipment. At this time, the side of the wood board to be processed is exposed, and the gluing and edge banding equipment are set on the side of the equipment for conveying the wood board. After the side of the wood board passes through the gluing equipment, the side of the wood board that is evenly coated with glue passes through the edge banding equipment, and the sealing tape can be pressed and fixed on the glue on the side of the wood board under pressure. However, this process has certain defects;

[0074] First, after the sealing tape is pressed and adhered to the side of the wooden board, the glue on the side of the wooden board will overflow due to the squeezing force;

[0075] Secondly, the overflowed glue is affected by the external environment temperature, and it is difficult for the sealing tape to solidify quickly on the side of the wooden board, which in turn affects the firmness of the sealing tape on the side of the wooden board;

[0076] Third, after the sealing tape is fixed on the wooden board until the glue solidifies, the glue that overflows to form bulges and the sealing tape that exceeds the thickness of the board need to be cleaned. Once the external force is too large, the bulges will cause pressure on the main body of the sealing tape, accompanied by shearing of the excessively long side of the sealing tape. In severe cases, it will cause the main body of the sealing tape on the side of the wooden board to loosen and fall off.

[0077] The device is provided with three evenly distributed sliders 750 in the slide grooves at the top of the third base 610 and the fourth base 620, and an oblique hole that can adapt to the bevel of the wooden board 100 is opened inside the slider 750. When the guide column 760 is installed in the pre-installed hole inside the slider 750, the three booster rollers 770 can quickly adapt to the bevel angle of the wooden board 100. At the same time, the angle of the calibration piece 630 also needs to be set according to the bevel of the wooden board 100. At this time, the edge banding 200 straightened and calibrated by the calibration piece 630 can be pressed on the glue on the bevel of the wooden board 100 under the extrusion of the three booster rollers 770.

[0078] When solutions of different temperatures are injected into the three boosting rollers 770, the temperatures of the main bodies of the three boosting rollers 770 may be in a gradual state. As the edge banding 200 is squeezed by the three boosting rollers 770 in sequence, the glue on the bevel of the wooden board 100 may be quickly solidified after contacting the three boosting rollers 770. At this time, the overflowing glue forms a semi-dry state under the action of the three gradient temperature boosting rollers 770, and the two scrapers 870 arranged at the top and bottom of the bevel of the wooden board 100 may scrape off the glue that has not been fully solidified. At the same time, the four pressing pieces 882 may provide auxiliary pressing force to the sides of the edge banding 200 that exceed the thickness of the wooden board 100. Finally, the two scrapers 870 may non-destructively cut off the excess part of the edge banding 200, which may reduce the color difference caused by the solidified glue on the surface of the wooden board 100 and avoid the edge banding 200 from loosening or falling off on the bevel of the wooden board 100.

[0097] The first spring 560 bears pressure on the rectangular slider in the first tensioning member 540;

[0098] The second spring 660 is pressed against the rectangular slider in the second tensioning member 640 .

[0099] Preferably, the inner roller of the first tensioning member 540 cooperates with the fixed pressure wheel 530 to provide initial tensioning constraint for the actively delivered edge banding 200 to prevent the edge banding 200 from falling off during delivery, wherein the first tensioning member 540 and the second tensioning member 640 move laterally along the combined first base 510, the second base 520, the third base 610, and the fourth base 620, so that the delivered edge banding 200 can be selectively tensioned and regulated.

[0106] A liquid injection cavity is provided inside the pressure roller 770 .

[0107] Preferably, the spacing between the three pressure rollers 770 is set according to three slide grooves. When the temperature of the solution injected into the inner cavity of the three pressure rollers 770 changes gradually, the pressurized edge banding strip 200 can reduce the interference of the external ambient temperature, thereby effectively improving the curing efficiency of the edge banding strip 200 on the side of the wooden board 100.

[0109] Preferably, the surface of the board guide 840 is coated with a glaze layer that reduces friction resistance, and the board guide 840 is composed of a Z-shaped plate and a transverse plate, and the transverse plate is located on the side of the wooden board 100.

[0111] The working principle and use process of the present invention: the bevel edge banding machine is mainly used to seal and apply adhesive pads to wood pre-cut into inclined sides, so as to protect the sides of the wooden board and improve the aesthetics of the wooden board. After the wooden board is initially cut, the worker needs to deliver the pre-processed board into the edge banding machine. As the side of the wooden board passes through the gluing component in the edge banding machine, the bevel of the board can be evenly coated with glue liquid, and then the feeding equipment for conveying the sealing tape needs to continuously deliver the sealing tape along the bevel of the horizontally moving wooden board, and finally, under the coordinated operation of the separately arranged booster component, the sealing tape is It can be pressed tightly on the bevel of the wooden board. However, when the existing sealing machine is used according to the above steps, there are still certain defects. After the glue is applied to the bevel of the wooden board, as the sealing tape squeezes the bevel of the wooden board, the glue will overflow to the top and bottom of the wooden board under the action of pressure, thereby causing glue overflow. Once the glue solidifies, the convex points formed by the overflow of the glue are scraped off by the workers. The convex points formed by the glue will cause secondary relaxation of the sealing tape, which may cause the sealing tape to fall off in severe cases. At the same time, the long-term retention of the glue on the wooden board will also affect the color of the board itself.

[0112] The device is arranged at the side of the wood board transporting device. When the outer end of the edge banding 200 is guided by the second tensioning member 640 and delivered along the bevel of the wood board under the state of being straightened and calibrated by the calibration member 630, the edge banding 200 squeezed by the three pressure rollers 770 can be pressed against the bevel of the wood board coated with glue. At the same time, the solutions of different temperatures transferred to the three return pipes 780 and the three pressure rollers 770 through the three water pipes 790 can radiate the edge banding 200 with gradual temperature. According to the traveling direction of the wood board, the temperature of the solution injected into the three pressure rollers 770 decreases successively. At this time, the edge banding 200 can be quickly cured after being pressed and attached to the bevel of the wood board, and the glue squeezed by the edge banding 200 can be quickly cured and cooled.

[0113] When the edge banding 200 is squeezed by the three pressure rollers 770 and causes glue overflow on the bevel of the wooden board 100, the glue that is cured by the last low-temperature pressure roller 770 can be scraped off by the two scrapers 870 before it is completely cured. At this time, the top and bottom edges of the edge banding 200 that exceed the thickness of the side edge of the wooden board 100 are restrained by the two pressure pieces 882 and are cut off by the two scrapers 870. At this time, the two pressure pieces 882 can stabilize and cut off the side edges of the edge banding 200 that exceed the specification, so as to avoid the problem that the edge banding on the bevel of the wooden board 100 falls off due to excessive shear pressure on the side edges of the edge banding 200 that are too long.

[0114] When the external environment temperature changes and affects the curing and shearing force of the beveled edges of the edge banding tape 200 and the wooden board 100, the two chassis 850 are powered by the wire 860. At this time, the two chassis 850 under cloud control can release heat for the two scrapers 870, thereby improving the rapid shearing of the side edges of the edge banding tape 200 and leveling the glue at the beveled edges of the wooden board 100.

[0115] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
