Description

Technical Field

[0001] This application relates to the field of sheet edge banding technology, and particularly to a sheet edge banding machine. Background Art

[0002] A sheet is a sheet or block material made by processing materials such as wood, and is mainly used in the construction industry as components for walls, ceilings or floors; in the existing technology during the processing of sheets, the edge banding strip is adhesively fixed to the edge of the sheet through glue to complete the edge banding processing of the sheet.

[0003] When the edge banding strip on the sheet is chamfered and cut by a saw blade, the residual edge generated during the cutting of the closing strip is easily adhered to the surface of the sheet, and it is necessary for workers to process the residual edge adhered to the sheet, which increases the workload of the workers, prolongs the processing cycle of the sheet, and thus increases the production cost of the sheet. Summary of the Invention

[0004] In order to improve the problem of the production cost of sheets, this application provides a sheet edge banding machine.

[0005] A sheet edge banding machine provided by this application adopts the following technical solutions: A sheet edge banding machine includes a machine base, a transportation component, an edge banding device, a chamfering component and a cleaning component. The surface of the machine base is provided with an edge banding station, a chamfering station and a cleaning station at intervals. The edge banding device is connected to the surface of the machine base facing the edge banding station, and the edge banding device can adhesively fix the edge banding strip to the edge of the sheet through glue. The chamfering component is connected to the surface of the machine base facing the chamfering station, and the chamfering component can chamfer and cut the end face of the edge banding strip at the chamfering station. The transportation component includes a positioning seat, a conveyor belt and a plurality of driving rollers. The positioning seat is connected to the surface of the machine base, and a positioning gap for the end of the sheet to slide is left between the positioning seat and the machine base. The conveyor belt is connected to the surface of the machine base facing the positioning gap, and the surface of the conveyor belt is for placing the sheet. The conveyor belt can drive the sheet to pass through the edge banding station, the chamfering station and the cleaning station in sequence. The plurality of driving rollers are rotatably connected to the surface of the positioning seat facing the positioning gap at intervals. The surface of the driving roller rolls in contact with the surface of the sheet, and the driving roller and the conveyor belt surface abut against both sides of the sheet to form positioning. The cleaning component includes a cleaning cylinder, a cleaning plate and a cleaning seat. The cleaning seat is connected to the surface of the machine base facing the cleaning station. The cleaning cylinder is connected to the surface of the positioning seat facing the cleaning seat. The cleaning plate is connected to the surface of the piston rod of the cleaning cylinder. The cleaning plate and the cleaning seat are located on both sides of the positioning gap. When the conveyor belt drives the sheet at the chamfering station to move to the cleaning station, the residual edge adhered to the sheet is located on the surface of the cleaning seat. The piston rod of the cleaning cylinder extends, and the surface of the cleaning plate and the surface of the cleaning seat clamp both sides of the residual edge to form a limit. The conveyor belt drives the sheet away from the cleaning station, and the residual edge is separated from the surface of the sheet.

[0006] By adopting the above technical solution, the staff sequentially place multiple plates on the surface of the conveyor belt. The end of the plate to be edge-sealed is embedded in the positioning gap. The surface of the driving roller and the surface of the conveyor belt abut against both sides of the plate to form positioning, thereby improving the stability of the conveyor belt driving the plate to move. The conveyor belt drives the plate to pass through the edge-sealing station, the chamfering station, and the cleaning station in sequence. The edge-sealing device adheres and fixes the edge banding strip to the edge of the plate through glue, realizing the automatic processing of edge-banding the plate. The chamfering component chamfers and cuts the end face of the edge banding strip at the chamfering station, realizing the automatic chamfering and cutting of the edge banding strip of the plate. The residual edge generated by the chamfering and cutting of the edge banding strip adheres to the surface of the plate. When the conveyor belt drives the plate at the chamfering station to move to the cleaning station, the residual edge is placed on the surface of the cleaning seat. The piston rod of the cleaning cylinder extends, and the surface of the cleaning plate and the surface of the cleaning seat clamp both sides of the residual edge to form a limit. The conveyor belt continues to drive the plate away from the cleaning station, and the residual edge detaches from the plate, realizing the automatic cleaning of the residual edge adhered to the plate. There is no need for the staff to process the residual edge adhered to the plate, reducing the work burden on the staff, completing the automatic processing of edge-banding the plate, shortening the processing cycle of the plate, and thus reducing the production cost of the plate.

[0007] Optionally, the cleaning component further includes a clamping plate and a cleaning nozzle. The clamping plate is connected to the surface of the machine base facing the cleaning station. The clamping plate is located on the side of the cleaning seat away from the chamfering station. The surface of the clamping plate facing the positioning gap is provided with a clamping cavity for the residual edge to be embedded. The cleaning nozzle is connected to the surface of the positioning seat facing the clamping plate. The air outlet end of the cleaning nozzle faces the clamping cavity, and the air impacts the residual edge in the clamping cavity through the air outlet end of the cleaning nozzle, driving the residual edge to detach from the plate.

[0008] By adopting the above technical solution, the conveyor belt drives the plate close to the clamping plate from the cleaning seat. The residual edge adhered to the end of the plate is embedded in the clamping cavity. The inner wall of the clamping cavity abuts against the surface of the residual edge to form a limit, realizing the limit of the residual edge in the clamping cavity. At the same time, the air impacts the residual edge in the clamping cavity through the air outlet end of the cleaning nozzle, driving the residual edge to detach from the plate, realizing the secondary cleaning of the residual edge adhered to the surface of the plate, improving the cleaning efficiency of the plate, shortening the processing cycle of the plate, and thus reducing the production cost of the plate.

[0009] Optionally, the chamfering component includes a first cutting seat, a second cutting seat, a first saw blade, and a second saw blade.

The second saw blade is rotatably connected to the surface of the second cutting seat facing the positioning gap. The first saw blade and the second saw blade are located on both sides of the positioning gap, and the cutting ends of the first saw blade and the second saw blade can respectively abut against both ends of the width direction of the edge banding strip.

[0010] By adopting the above technical solution, when the conveyor belt drives the board at the edge banding station close to the chamfering station, the end of the board with the edge banding strip is located within the positioning gap, the cutting ends of the first saw blade and the second saw blade abut against both ends in the width direction of the edge banding strip, the first saw blade and the second saw blade rotate, and the first saw blade and the second saw blade complete the automatic chamfering cutting process for both ends in the width direction of the edge banding strip, thereby improving the processing efficiency of the board.

[0011] Optionally, the edge banding device includes a glue injection seat, a tray, a cutting assembly, and an edge banding assembly.

The edge banding assembly is connected to the surface of the machine base facing the edge banding station, and the edge banding assembly is located on one side of the fixed seat close to the chamfering station. The edge banding assembly can adhere and fix the edge banding strip after segmented cutting to the edge of the board within the positioning gap.

[0012] By adopting the above technical solution, when the conveyor belt drives the board close to the edge banding station, glue is coated on the edge of the board within the positioning gap through the glue outlet end of the glue injection seat. The conveyor belt continues to drive the board to move, and the edge banding strip on the tray passes through the fixed cavity. According to the length of the edge banding strip required for the board, the cutting cylinder extends, driving the blade close to the edge banding strip. The cutting end of the blade abuts against the surface of the edge banding strip and performs segmented cutting on the edge banding strip, making the length of the edge banding strip equal to the length required for edge banding the board, thereby improving the edge banding quality of the board. The edge banding assembly adheres and fixes the edge banding strip after segmented cutting to the edge of the board within the positioning gap, completing the automatic edge banding processing of the board edge.

[0013] Optionally, the edge banding assembly includes a guiding roller and a plurality of pressing rollers. The plurality of pressing rollers are rotatably connected to the surface of the machine base facing the edge banding station at intervals. The arrangement direction of the pressing rollers is parallel to the transportation direction of the conveyor belt. The roller surface of the pressing roller faces the positioning gap, and the roller surface of the pressing roller can press and adhere the edge banding strip after segmented cutting to the edge of the board. The guiding roller is rotatably connected to the surface of the machine base facing the edge banding station, and the guiding roller is located between the pressing rollers and the fixed seat. The roller surface of the guiding roller guides the edge banding strip after segmented cutting in the fixed cavity to abut against the roller surface of the pressing roller.

[0014] By adopting the above technical solution, when the cutting cylinder extends, driving the blade close to the edge strip, the cutting end of the blade abuts against the surface of the edge strip and completes the segmented cutting of the edge strip. The edge strip segmented and cut in the guiding roller guiding fixed cavity abuts against the roller surface of the abutting roller. The roller surface of the abutting roller abuts against the edge strip segmented and cut and drives the other end of the edge strip to abut tightly against and adhere to the edge of the plate fixed in the positioning gap, thus completing the automatic edge wrapping of the plate edge.

[0015] Optionally, the edge sealing device further includes a guiding component. The guiding component is connected to the surface of the machine base facing the edge sealing station. The guiding component is located between the fixed seat and the tray. The guiding component includes a guiding plate, a guiding seat and a guiding block. The guiding plate and the guiding seat are spaced and connected to the surface of the machine base. A guiding gap for the edge strip on the tray to pass through is left between the guiding plate and the guiding seat. The guiding block is connected to the surface of the machine base. The guiding block is located between the fixed seat and the guiding plate. A guiding cavity for the edge strip to pass through is formed on the surface of the guiding block. The edge strip on the tray passes through the guiding gap, the guiding cavity and the fixed cavity in sequence. The inner wall of the guiding cavity abuts against the surface of the edge strip to form positioning.

[0016] By adopting the above technical solution, the guiding component is located between the cutting component and the tray. The edge strip on the tray passes through the guiding gap, the guiding cavity and the fixed cavity in sequence. The inner wall of the guiding cavity abuts against the surface of the edge strip to form positioning, enabling the edge strip on the tray to stably pass through the fixed cavity, thereby improving the stability of the blade for segmented cutting of the edge strip.

[0017] Optionally, it further includes a dust removal component. A dust removal station is provided on the surface of the machine base. The dust removal station is located on the side of the edge sealing station away from the chamfering station. The conveyor belt can drive the plate from the dust removal station to the edge sealing station.

The plurality of air extraction boxes are spaced and connected to the surface of the positioning seat facing the dust removal station. The arrangement direction of the air extraction boxes is parallel to the transportation direction of the conveyor belt. The air extraction end of the air extraction box faces the edge of the plate in the positioning gap, and the dust removal base is located on the side of the air extraction box away from the edge sealing station.

[0018] By adopting the above technical solution, when the sheet is placed on the surface of the conveyor belt, the edge of the sheet is embedded in the positioning gap. The conveyor belt drives the sheet towards the dust removal station. Air impacts the edge of the sheet in the positioning gap through the air outlet end of the dust removal nozzle, and the air takes away the dust adhering to the edge of the sheet, achieving the preliminary cleaning of the edge of the sheet. The conveyor belt drives the sheet to continue moving. The air extraction end of the air extraction box faces the edge of the sheet in the positioning gap. The air extraction end of the air extraction box sucks the air at the edge of the sheet, and the air drives the dust at the edge of the sheet into the inner cavity of the air extraction box, achieving multiple cleanings of the edge of the sheet, making it difficult for the dust to adhere to the edge of the sheet, thereby improving the quality of edge banding of the sheet edge.

[0019] Optionally, it further includes an alignment component. An alignment station is provided on the surface of the machine base. The alignment station is located between the edge banding station and the chamfering station. The conveyor belt can drive the sheet at the edge banding station from the alignment station to the chamfering station. The alignment component includes an alignment seat one, a motor one, an alignment rod, and an alignment roller one. The alignment seat one is connected to the surface of the machine base facing the alignment station. The motor one is connected to the top surface of the alignment seat one. The end of the alignment rod is connected to the motor shaft of the motor one. The axis of the alignment rod and the axis of the motor of the motor one are perpendicular to each other. The alignment roller one is rotatably connected to the end of the alignment rod away from the motor one. The axis of the alignment roller one and the axis of the motor of the motor one are parallel to each other. An alignment cavity one for the edge of the sheet to abut is left between the alignment rod and the alignment roller. When the sheet is at the alignment station, the motor one drives the alignment rod to rotate towards the direction close to the positioning gap, and the inner wall of the alignment cavity one abuts the edge of the sheet and corrects the orientation of the sheet in the positioning gap.

[0020] By adopting the above technical solution, when the conveyor belt drives the sheet at the edge banding station into the alignment station, the motor one drives the alignment rod to rotate towards the direction close to the positioning gap. The alignment cavity one faces the positioning gap. The edge of the sheet in the positioning gap is embedded in the inner wall of the alignment cavity one. The inner wall of the alignment cavity one abuts the edge of the sheet and corrects the orientation of the sheet in the positioning gap, thereby ensuring the stability of the chamfering component for chamfering and cutting the edge of the sheet.

[0021] Optionally, the alignment component further includes an alignment seat two, a connecting rod one, a connecting rod two, a driving seat, a motor two, and an alignment roller two. The alignment seat two is connected to the surface of the machine base. The alignment seat two is located on the side of the alignment seat one close to the chamfering station. The ends of the connecting rod one and the connecting rod two are rotatably connected to the surface of the alignment seat two at intervals. The other ends of the connecting rod one and the connecting rod two are rotatably connected to the surface of the driving seat at intervals. The motor two is connected to the surface of the driving seat. The motor shaft of the motor two faces the positioning gap. The alignment roller two is coaxially connected to the motor shaft of the motor two. The end face of the alignment roller two can abut the end face of the edge banding strip in the positioning gap and correct the orientation of the sheet in the positioning gap.

[0022] By adopting the above technical solution, when the conveyor belt drives the sheet to approach the second alignment seat from the first alignment seat, the edge of the sheet adhered with the edge banding strip in the positioning gap faces the end face of the second alignment roller. The first connecting rod and the second connecting rod rotate, driving the driving seat to approach the positioning gap. The end face of the second alignment roller abuts against the end face of the edge banding strip and corrects the orientation of the sheet in the positioning gap, thereby ensuring the stability of the chamfering assembly for chamfering and cutting the edge of the sheet.

[0023] Optionally, the alignment assembly further includes a third alignment seat, a power cylinder, a fixing plate, and a rotating rod. The two ends of the fixing plate in the length direction are respectively connected to the opposite end faces of the first connecting rod and the second connecting rod. The third alignment seat is connected to the surface of the machine base. The third alignment seat is located on the side of the second alignment seat away from the first alignment seat. The power cylinder is connected to the surface of the third alignment seat facing the second alignment seat. One end of the rotating rod is rotatably connected to the piston rod of the power cylinder, and the other end of the rotating rod is rotatably connected to the plate surface of the fixing plate. When the piston rod of the power cylinder extends, the rotating rod receives the power of the power cylinder and drives the first connecting rod and the second connecting rod to rotate, and the driving seat moves away from the positioning gap.

[0024] By adopting the above technical solution, when the edge of the sheet in the positioning gap faces the end face of the second alignment roller, the piston rod of the power cylinder contracts. The rotating rod receives the power of the power cylinder and drives the first connecting rod and the connecting rod to rotate. The driving seat approaches the positioning gap. The end face of the second alignment roller abuts against the end face of the edge banding strip and adjusts the orientation of the sheet in the positioning gap. When the piston rod of the power cylinder extends, the rotating rod receives the power of the power cylinder and drives the first connecting rod and the connecting rod to rotate. The driving seat moves away from the positioning gap, ensuring that when the conveyor belt drives the sheet to approach the second alignment roller, it is not easy to collide between the second alignment roller and the sheet, thereby improving the stability of the conveyor belt for transporting the sheet.
