Description

Technical Field

[0001] The invention belongs to the technical field of board edge banding equipment, and specifically refers to a board edge banding machine for producing wooden furniture. Background Art

[0002] The board edge banding machine is a mechanical equipment that performs edge banding on the edge of the board. It uses automated machinery to complete the traditional manual edge banding operation process. It is widely used in furniture manufacturing, decoration and decoration, wooden door manufacturing and other industries. The edge banding machine mainly includes gluing, edge banding, end trimming, trimming, polishing and other processes. The board is transported by a conveyor belt and passes through the above processes at one time to finally complete the edge banding of the board.

[0003] The glue used in the board edge banding machine is EVA hot melt adhesive, which has a fast curing speed. After the board is coated with glue and the edge strips are bonded to the edges, it can cure within seconds, so that subsequent processing steps such as trimming, trimming, and polishing can be carried out quickly, shortening the processing time. However, the curing speed of EVA hot melt adhesive is affected by the ambient temperature. When the ambient temperature is low in winter, the curing time of EVA hot melt adhesive is shortened, resulting in loose bonding of the edge strips. When the ambient temperature is high in summer, the curing time of EVA hot melt adhesive is increased. When the wooden board moves to processes such as trimming, trimming, and polishing, it is easy to cause adhesion to the tool, resulting in reduced processing accuracy. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a board edge banding machine for wooden furniture production, which at least partially solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a board edge banding machine for wooden furniture production, comprising: A machine platform, wherein a conveyor belt for conveying the plate is disposed on the machine platform, and along the conveying direction of the conveyor belt, an edge welt assembly for welting and a finishing assembly for trimming are sequentially disposed on the machine platform; The machine platform is also provided with a plurality of edge pressing rollers distributed along the conveying direction of the conveyor belt, and the edge pressing rollers are located between the edge pasting component and the finishing component; The edge pressing roller comprises a metal roller and two connecting tubes, the two connecting tubes are respectively fixed at two ends of the metal roller, a cover plate is fixed on the two connecting tubes, a rubber sleeve is sleeved on the outer side of the metal roller, and the two ends of the rubber sleeve are respectively connected to the two cover plates, so that a sealed accommodating cavity is formed between the metal roller and the rubber sleeve, and the connecting tube is connected to the accommodating cavity; A cooling water circulation machine, wherein the connecting pipes at both ends of the metal roller are respectively connected to a water supply end and a return end of the cooling water circulation machine.

[0006] Furthermore, a heating plate is provided on the machine platform, and the heating plate is located on one side of the starting end of the conveyor belt.

[0007] Furthermore, a delivery pump is provided at the water supply end of the cooling water circulation machine, and a reflux pump is provided at the reflux end of the cooling water circulation machine, for controlling the water inflow and water discharge of the accommodating chamber.

[0008] Furthermore, one end of the connecting pipe located outside the accommodating cavity is connected to a water pipe, and the connecting pipe is connected to the cooling water circulation machine through the water pipe.

[0009] Furthermore, an elastic bracket is provided on one side of the edge pressing roller, and the edge pressing roller is rotatably connected to the elastic bracket.

[0010] Furthermore, a bracket is provided on one side of the machine platform close to the edge holding roller, and the elastic bracket is connected to the bracket.

[0011] Furthermore, the elastic bracket includes a connecting frame, a fixed seat and a sliding rod, the connecting pipe is rotatably connected to the connecting frame, one end of the sliding rod is fixed to the connecting frame, the other end of the sliding rod is slidably inserted into the fixed seat, and the sliding direction of the sliding rod is perpendicular to the conveying direction of the conveyor belt, so that the edge pressing roller can move in a direction close to or away from the conveyor belt; The slide bar is provided with a spring, and the spring is configured to apply a thrust to the edge holding roller in the direction of the conveyor belt.

[0012] Furthermore, a screw rod is provided on one side of the sliding rod, the screw rod is arranged parallel to the sliding rod, one end of the screw rod is fixed on the connecting frame, the other end of the screw rod is slidably inserted on the fixing seat, and a nut is connected to the end of the screw rod away from the connecting frame.

[0013] Furthermore, a water delivery hole is provided at one end of the connecting pipe located in the accommodating cavity, so that the connecting pipe is in communication with the accommodating cavity.

[0014] Furthermore, a lifting frame is fixed on the machine platform, and a plurality of pressing rollers distributed along the conveying direction of the conveyor belt are connected to the lifting frame, and the pressing rollers are located above the conveyor belt.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: 1. A sealed receiving chamber is formed between the metal roller and the rubber sleeve by arranging a rubber sleeve on the outside of the metal roller. When the ambient temperature is high, the cooling water circulation machine circulates cooling water into the receiving chamber. The cooling water circulating in the receiving chamber can cool the hot melt adhesive applied on the plate, accelerate its curing speed, and avoid the phenomenon of knife sticking in subsequent finishing, polishing and other processes.

[0016] 2. By setting a heating plate at the starting end of the conveyor belt, when the ambient temperature is low, the side of the plate that needs edge sealing is heated by the heating plate. When applying glue, due to the high temperature of the glue-coated surface of the plate, the cooling speed of the hot melt adhesive can be slowed down, the curing time of the hot melt adhesive can be increased, and the edge banding strip can be fully bonded, avoiding the problem of loose bonding caused by the hot melt adhesive curing too quickly.

[0017] 3. By expanding the rubber sleeve to a certain extent, when the plate moves to the edge pressing roller, the rubber sleeve is pressed against the metal roller by the plate. Since the rubber sleeve is relatively soft and in an expanded state, the rubber sleeve can better wrap the side of the plate and use water pressure to apply pressure to the edge banding strip to avoid the edge banding strip from being loosely fitted due to the uneven side of the plate.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0023] like Figure 1 As shown, the present invention proposes a board edge banding machine for wooden furniture production, including a machine platform 1, a conveyor belt 11, an edge banding component 2, a finishing component 3, an edge pressing roller 4 and a cooling water circulation machine 7.

[0024] The conveyor belt 11 is disposed on the machine platform 1 , the welt assembly 2 and the finishing assembly 3 are disposed on one side of the conveyor belt 11 , and the welt assembly 2 and the finishing assembly 3 are arranged in sequence along the transmission direction of the conveyor belt 11 .

[0025] Furthermore, a lifting frame 12 is fixed on the machine 1, and a plurality of pressing rollers 13 distributed along the conveying direction of the conveyor belt 11 are connected to the lifting frame 12, and the pressing rollers 13 are located above the conveyor belt 11. According to the thickness of the plate, the lifting frame 12 is adjusted so that the pressing rollers 13 on the lifting frame 12 and the conveyor belt 11 can clamp the plate. When the conveyor belt 11 conveys the plate, the pressing rollers 13 press the plate against the conveyor belt 11 from the top surface of the plate, so that the conveyor belt 11 can stably convey the plate. At the same time, the plate is fixed on the conveyor belt 11 by clamping the pressing rollers 13 and the conveyor belt 11, so as to avoid relative sliding between the plate and the conveyor belt 11 during edging and finishing.

[0026] Furthermore, a support rack 14 arranged parallel to the conveyor belt 11 is provided on one side of the machine 1, and the supporting surface of the support rack 14 is at the same height as the conveying surface of the conveyor belt 11, which can provide auxiliary support for larger plates.

[0027] Combination Figure 7As shown, the edge-adhesive component 2 includes a gluing component 21 and an edge-banding component 22. The plate passes through the gluing component 21 and the edge-banding component 22 in sequence under the transmission of the conveyor belt 11. When the plate passes through the gluing component 21, the gluing component 21 glues the side edge of the plate. The glued plate moves to the edge-banding component 22, and the edge-banding component 22 applies the edge-banding tape to the glued edge of the plate and fits it to the glued edge of the plate.

[0028] In a specific embodiment, the glue coating component 21 includes a glue pot and a continuously rotating glue coating roller. The glue pot continuously delivers hot melt glue to the glue coating roller. As the plate contacts and moves with the glue coating roller, the glue coating roller evenly coats the glue on the side of the plate.

[0029] Furthermore, the edge banding component 22 includes a tape feed wheel, a cutting knife and a support tray 15. The support tray 15 supports the edge banding tape. The tape feed wheel feeds the edge banding tape so that the edge banding tape fits the glue-coated edge of the board. Then, the cutting knife is used to cut the edge banding tape to complete the edge banding of the board.

[0030] Combination Figure 1 and Figure 2 As shown, the machine 1 is also provided with a plurality of edge pressing rollers 4 distributed along the conveying direction of the conveyor belt 11, and the edge pressing rollers 4 are located between the edge bonding component 2 and the finishing component 3. The plate with completed edge banding moves to the edge pressing rollers 4 under the conveyance of the conveyor belt 11, and the edge pressing rollers 4 pressurize the edge banding tape bonded to the plate to make the plate and the edge banding tape fit more firmly.

[0031] Furthermore, an elastic bracket 5 is provided on one side of the pressing roller 4, and a bracket 16 is provided on the side of the machine 1 close to the pressing roller 4. The elastic bracket 5 is connected to the bracket 16, and the pressing roller 4 is rotatably connected to the elastic bracket 5. The elastic bracket 5 supports the pressing roller 4, and the elastic bracket 5 is a movable bracket, so that the pressing roller 4 can move horizontally, and the direction of the pressing roller 4 is perpendicular to the transmission direction of the conveyor belt 11. At the same time, the elastic bracket 5 can apply elastic pressure to the pressing roller 4. Therefore, when the plate contacts the pressing roller 4, the pressing roller 4 is squeezed and pushed to one side by the plate. At this time, the elastic part on the elastic bracket 5 is compressed, and under the action of the elastic part, the pressing roller 4 applies pressure to the plate, so that the plate and the edge banding belt fit more firmly.

[0032] Combination Figure 7 As shown, the finishing component 3 includes a grinding component 31 and a polishing component 32. The grinding component 31 grinds and removes the edge banding strips protruding from both ends and both sides of the plate to make the edge of the edge banding strip flush with the plate. After grinding is completed, the polishing component 32 polishes the edge banding of the plate to remove the knife marks caused by grinding and make the edge banding more beautiful.

[0033] In a specific embodiment, the grinding component 31 includes two cutting tools that can track the plate, and grind the two ends and the upper and lower sides of the plate respectively.

[0034] Furthermore, the polishing component 32 includes two polishing wheels symmetrically arranged up and down, which polish the upper and lower sides of the plate respectively to modify the corrugated marks produced by grinding.

[0035] Combination Figure 3 , Figure 4 and Figure 5 As shown, the edge pressing roller 4 includes a metal roller 41 and connecting pipes 42 respectively fixed at both ends thereof, a cover plate 43 is fixed on both connecting pipes 42, a rubber sleeve 44 is sleeved on the outer side of the metal roller 41, and both ends of the rubber sleeve 44 are respectively connected to the two cover plates 43, the metal roller 41, the connecting pipe 42, the cover plate 43 and the rubber sleeve 44 are coaxially arranged, the inner diameter of the rubber sleeve 44 is larger than the outer diameter of the metal roller 41, the distance between the two cover plates 43 is larger than the axial length of the metal roller 41, so that a sealed accommodating cavity is formed between the metal roller 41 and the rubber sleeve 44, and a water delivery hole 421 is opened at one end of the connecting pipe 42 located in the accommodating cavity, so that the connecting pipe 42 is connected to the accommodating cavity; The connecting pipes 42 at both ends of the metal roller 41 are respectively connected to the water supply end and the return end of the cooling water circulation machine 7. The cooling water circulation machine 7 delivers cooling water to the receiving chamber through the connecting pipe 42 at one end, and the cooling water in the receiving chamber flows back to the cooling water circulation machine 7 through the connecting pipe 42 at the other end, so that there is always circulating cooling water in the receiving chamber. In this way, when the board coated with glue and with edge banding moves to the edge pressing roller 4, the board contacts the rubber sleeve 44 and presses the rubber sleeve 44 against the metal roller 41, and the metal roller 41 applies pressure to the edge banding. As the board is conveyed, the metal roller 41, the cover plate 43 and the rubber sleeve 44 are dragged and rotated, thereby rolling the board; When the ambient temperature is high, the cooling water circulation machine 7 circulates cooling water into the accommodating chamber. The cooling water circulating in the accommodating chamber can cool the hot melt adhesive applied to the plate, accelerate its solidification speed, and avoid knife sticking in subsequent finishing, polishing and other processes. When the ambient temperature is within the normal range, the cooling water circulation machine 7 can be shut down to reduce energy consumption.

[0036] Furthermore, a heating plate 6 is provided on the machine 1, and the heating plate 6 is located on one side of the starting end of the conveyor belt 11, and the heating plate 6 and the edge bonding component 2 are located on the same side (such as Figure 2 As shown), the heating plate 6 can heat the side of the plate that needs edge sealing.

[0037] In this way, when the ambient temperature is low, the plate is at the starting end of the conveyor belt 11 (the plate has not been coated with glue at this time), and the side of the plate that needs to be sealed contacts the heating plate 6, and the heating plate 6 heats the side of the plate that needs to be sealed. Then, when the plate is conveyed to the edge bonding component 2 for gluing, the temperature of the glue-coated surface of the plate is relatively high, which can slow down the cooling rate of the hot melt adhesive, increase the curing time of the hot melt adhesive, and make the edge banding strip fully bonded, thus avoiding the problem of loose bonding caused by the hot melt adhesive curing too quickly.

[0038] In a specific embodiment, one end of the connecting pipe 42 located outside the accommodating cavity is connected to a water pipe 45 , and the connecting pipe 42 is connected to the cooling water circulation machine 7 through the water pipe 45 .

[0039] Furthermore, the water pipe 45 is connected to the connecting pipe 42 through a mechanical seal. When the edge pressing roller 4 is dragged and rotated, the connecting pipe 42 rotates synchronously, while the water pipe 45 does not rotate. Under the action of the mechanical seal, the water pipe 45 can always maintain a seal with the connecting pipe 42 to avoid leakage.

[0040] Combination Figure 7 As shown, a delivery pump 8 is provided at the water supply end of the cooling water circulation machine 7, and a reflux pump 9 is provided at the reflux end of the cooling water circulation machine 7. The cooling water is circulated into the accommodating chamber by the delivery pump 8 and the reflux pump 9. At the same time, the water intake and discharge of the accommodating chamber can be controlled. The flow difference between the delivery pump 8 and the reflux pump 9 can be used to expand or contract the rubber sleeve 44. When the water supply amount is greater than the reflux amount, the rubber sleeve 44 expands, and when the water supply amount is less than the reflux amount, the rubber sleeve 44 contracts.

[0041] In this way, when circulating cooling water into the accommodation chamber, the delivery pump 8 and the reflux pump 9 can be controlled first to make the water delivery amount greater than the reflux amount, so that the rubber sleeve 44 expands to a certain extent, and then the delivery pump 8 and the reflux pump 9 are controlled to make the water delivery amount and the reflux amount the same. At this time, the rubber sleeve 44 can maintain the current volume; When the sheet moves to the edge pressing roller 4, the rubber sleeve 44 is pressed against the metal roller 41 by the sheet. Since the rubber sleeve 44 is relatively soft and in an expanded state, the rubber sleeve 44 can better wrap the side of the sheet and use water pressure to apply pressure to the edge banding strip (such as Figure 5 and Figure 6 as shown), to avoid loose fitting of the edge banding due to uneven side of the board.

[0042] Furthermore, valves are provided on the water pipes 45 connected to the connecting pipes 42. When the hot melt adhesive does not need to be cooled, the cooling water circulation machine 7 can be shut down, and normal temperature water is circulated into the accommodating chamber through the delivery pump 8 and the reflux pump 9. After the rubber sleeve 44 expands to a certain extent, the delivery pump 8 and the reflux pump 9 are shut down and the valves are closed. At this time, the accommodating chamber is sealed and maintained in an expanded state, saving energy consumption.

[0043] Combination Figure 5 As shown, the elastic bracket 5 includes a connecting frame 51, a fixed seat 52 and a sliding rod 53. The fixed seat 52 is fixed on the bracket 16. Bearings are provided at both ends of the connecting frame 51. The connecting pipes 42 at both ends of the metal roller 41 are rotatably connected to the connecting frame 51 through bearings. The fixed seat 52 is provided with a socket corresponding to the sliding rod 53. One end of the sliding rod 53 is fixed on the connecting frame 51, and the other end of the sliding rod 53 is slidably inserted in the socket of the fixed seat 52. The sliding direction of the sliding rod 53 is perpendicular to the transmission direction of the conveyor belt 11, so that the edge pressing roller 4 can move in the direction close to or away from the conveyor belt 11.

[0044] A spring 54 is provided on the slide bar 53, and the spring 54 is located between the connecting frame 51 and the fixed seat 52. When the edge pressing roller 4 is squeezed by the plate and moves away from the conveyor belt 11, the spring 54 is compressed. At this time, the spring 54 applies an elastic thrust to the edge pressing roller 4, so that the edge pressing roller 4 can apply pressure to the plate.

[0045] Furthermore, a screw rod 55 is provided on one side of the slide rod 53, and the screw rod 55 is arranged in parallel with the slide rod 53. A socket corresponding to the screw rod 55 is provided on the fixing seat 52. One end of the screw rod 55 is fixed on the connecting frame 51, and the other end of the screw rod 55 is slidably inserted into the corresponding socket of the fixing seat 52. The connecting frame 51 can be limited by the screw rod 55 and the slide rod 53 to prevent the connecting frame 51 from self-rotating. The end of the screw rod 55 away from the connecting frame 51 is connected with a nut 56. The cooperation between the nut 56 and the screw rod 55 plays a limiting role to prevent the sliding rod 53 from detaching from the fixing seat 52. At the same time, by adjusting the position of the nut 56 on the screw rod 55, the initial position of the edge pressing roller 4 can be adjusted. The closer the initial position of the edge pressing roller 4 is to the conveyor belt 11, the greater the distance that the plate squeezes and pushes the edge pressing roller 4 to move. Correspondingly, the longer the distance that the spring 54 is compressed, the greater the pressure applied by the edge pressing roller 4 to the plate, and vice versa.

[0046] The working principle of the present invention is as follows: the plate is placed on the initial section of the conveyor belt 11, clamped by the conveyor belt 11 and the pressure roller 13, and conveyed by the conveyor belt 11. The plate passes through the heating plate 6, the edge wedging component 2, the pressure roller 4 and the finishing component 3 in sequence. When the plate moves to the edge wedging component 2, it first contacts the glue roller of the glue coating component 21, and the glue pot continuously conveys hot melt glue to the glue coating roller. As the plate contacts and moves with the glue coating roller, the glue coating roller evenly coats the glue on the side of the plate, and then moves to the edge banding component 22. The tape feed wheel feeds the edge banding tape to make the edge banding tape fit the glued edge of the plate, and then uses the cutting tool to cut the edge banding tape. The cutting knife cuts the edge banding to complete the edge banding of the plate. The plate with edge banding is moved to the edge pressing roller 4 under the transmission of the conveyor belt 11. The edge pressing roller 4 presses the edge banding bonded to the plate to make the plate and the edge banding fit more firmly. Then the plate is conveyed to the finishing component 3. First, the two cutters of the grinding component 31 grind the two ends and the upper and lower sides of the plate respectively to remove the protruding edge banding strips so that the edge of the edge banding strip is flush with the plate. After the grinding is completed, the two polishing wheels of the polishing component 32 polish the upper and lower sides of the plate respectively to modify the corrugated marks caused by grinding. When the ambient temperature is low, the side of the plate that needs to be edge-sealed is heated by the heating plate 6, and then when the plate is conveyed to the edge-sealing assembly 2 for gluing, the higher the temperature of the gluing surface of the plate, the slower the cooling speed of the hot melt adhesive, the longer the curing time of the hot melt adhesive, and the more fully the edge-sealing strip is bonded, thus avoiding the problem of the hot melt adhesive curing too fast and causing a loose bond. When the ambient temperature is high, the cooling water circulation machine 7 circulates cooling water into the accommodating chamber. The cooling water circulating in the accommodating chamber can cool the hot melt adhesive applied on the plate, accelerate its curing speed, and avoid the phenomenon of knife sticking in subsequent finishing, polishing and other processes. When the ambient temperature is within the normal range, the cooling water circulation machine 7 can be stopped to reduce energy consumption; By expanding the rubber sleeve 44 to a certain extent, when the sheet moves to the edge pressing roller 4, the rubber sleeve 44 is pressed against the metal roller 41 by the sheet. Since the rubber sleeve 44 is relatively soft and in an expanded state, the rubber sleeve 44 can better wrap the side of the sheet and use water pressure to apply pressure to the edge banding strip (such as Figure 5 and Figure 6 as shown), to avoid loose fitting of the edge banding due to uneven side of the board.

[0047] In summary of the above embodiments: by arranging the rubber sleeve 44 on the outer side of the metal roller 41, a sealed accommodating chamber is formed between the metal roller 41 and the rubber sleeve 44. When the ambient temperature is high, the cooling water circulation machine 7 circulates cooling water into the accommodating chamber. The cooling water circulating in the accommodating chamber can cool the hot melt adhesive applied on the plate, accelerate its curing speed, and avoid the phenomenon of knife sticking in subsequent finishing, polishing and other processes. By arranging a heating plate 6 at the starting end of the conveyor belt 11, when the ambient temperature is low, the heating plate 6 heats the side of the plate that needs to be edge-sealed, and then when the plate is conveyed to the edge-sealing assembly 2 for gluing, the temperature of the gluing surface of the plate is high, which can slow down the cooling speed of the hot melt adhesive, increase the curing time of the hot melt adhesive, and make the edge banding strip fully bonded, avoiding the problem of loose bonding caused by too fast curing speed of the hot melt adhesive; By expanding the rubber sleeve 44 to a certain extent, when the sheet moves to the edge pressing roller 4, the rubber sleeve 44 is pressed against the metal roller 41 by the sheet. Since the rubber sleeve 44 is relatively soft and in an expanded state, the rubber sleeve 44 can better wrap the side of the sheet and use water pressure to apply pressure to the edge banding strip (such as Figure 5 and Figure 6 as shown), to avoid loose fitting of the edge banding due to uneven side of the board.
