Description

Technical Field

[0001] This invention specifically relates to a portable PUR edge banding machine for edge banding of furniture panels, belonging to the technical field of PUR edge banding machines. Background Technology

[0002] Currently, on-site furniture making and decoration often uses ordinary EVA glue, which is not very strong. Therefore, some manufacturers use PUR edge banding machines to band the edges of furniture. For example, Chinese Patent Publication No. CN222590159U discloses a board edge banding machine, including a machine housing, a board conveyor, a board milling device, a board pressing device, and a board post-processing device. This structure uses spraying instead of roller coating, achieving complete glue application to linear, curved, and irregular groove surfaces, ensuring the pressing quality of the board edge banding, improving the tightness of the connection between the edge banding board and the inner wall of the mounting groove, thereby enhancing the connection strength between the edge banding board and the board to be processed; another example is... Patent publication number: CN116551807A discloses a board edge banding and side hole machine, including a frame body. The top of the frame body is sequentially equipped with a board preheating mechanism, an adhesive application mechanism, a tape application mechanism, a front and rear trimming mechanism, an edge trimming mechanism, and a side hole mechanism. This structure achieves side hole operation that is synchronous with the edge banding machine by adding the side hole mechanism to the rear section of the fully automatic edge banding machine, forming a fully automatic integrated machine for edge banding and side hole operation. However, existing PUR edge banding machines are all large-scale factory equipment. When making furniture on-site, it is impossible to perform edge banding on the boards. In addition, when the finished furniture boards need to be cut, they need to be returned to the factory for sealing processing. Summary of the Invention

[0003] To address the aforementioned issues, this invention proposes a portable PUR edge banding machine for furniture panels. It features an integrated machine head molding structure, making it suitable for various edge banding scenarios and ensuring a firm edge banding bond.

[0004] The portable PUR edge banding machine for furniture panels of the present invention comprises: The machine head serves as the load-bearing unit of the entire edge banding machine and integrates the electric drive module and pneumatic control module inside the machine head. The pressure roller is rotatably mounted on the front end of the top of the machine head and can press the glued board and the edge banding tape together, so that the edge banding tape and the board are bonded together as one; The glue application unit is arranged side by side with the pressure roller on the top of the machine head, and the glue application end of the glue application unit is on the same plane as the front end of the pressure roller. A touch switch is installed at the front end of the top of the machine head and is located on the side away from the pressure roller; The touch switch, the glue application end of the glue application unit, and the pressure roller are arranged on the edge sealing travel path of the board. During edge banding, the board first contacts the touch switch, then enters the glue application unit for glue application, and finally the glued surface of the board is bonded to the edge banding tape by the pressure roller. The adhesive feeding unit has a connecting channel between its outlet end and the inlet end of the coating unit. A locking cylinder for locking the channel is provided outside the connecting channel. When coating is performed, the piston rod of the locking cylinder drives the locking head to disengage from the connecting channel. At this time, the adhesive feeding unit feeds the coating unit. After the feeding is completed, the connecting channel can be re-locked by the locking cylinder. A control console, which is fixed to the rear side of the machine head by a bracket; An edge banding tape guide, comprising two guide plates forming a V-shaped structure, with the output end of the guide plate facing the pressure roller; the two guide plates form the edge banding tape guide, and the edge banding tape enters between the two guide plates. Due to the narrowing of the output ends of the two guide plates, the edge banding tape can be centered and aligned, allowing it to be accurately fed into the front of the pressure roller, awaiting adhesion between the glued board and the edge banding tape; The tape feeding unit includes a tape feeding roller disposed at the input end of the edge banding tape guide and rotatably disposed at the top of the machine head. A tape feeding cylinder is fixed to the side of the tape feeding roller, and a slide block is fixed to the telescopic end of the tape feeding cylinder. A driven roller that is in contact with the tape feeding roller is rotatably disposed at the end of the slide block. The edge banding tape roll on the external feeding tray is pulled into the space between the tape feeding roller and the driven roller. When edge banding tape needs to be fed, the slide block is driven to slide by the tape feeding cylinder, and the driven roller is driven to move closer to the tape feeding roller, so that the tape feeding roller and the driven roller clamp the edge banding tape and transfer it as the tape feeding roller rotates, thereby feeding the edge banding tape into the input end of the edge banding tape guide, and thus feeding the edge banding tape into the pressure roller side. The tape-cutting unit includes a tape-cutting cylinder fixed to the top of the machine head, with a cutter head fixed to the telescopic end of the tape-cutting cylinder; the tape-cutting cylinder is located behind the pressure roller; the cutter head is positioned directly between the input end of the edge-sealing tape guide and the tape feeding unit; when the tape-cutting unit is working, the tape-cutting cylinder drives the cutter head forward, thereby allowing the cutter head to enter the edge-sealing tape transmission path; after the edge cutting is completed, the tape-cutting cylinder automatically resets; A drive motor is fixed inside the machine head. The drive motor is connected to the transmission gears at the bottom of the drive pressure roller and the belt feeding roller via a transmission chain. The drive motor drives the transmission chain to rotate, and the transmission chain drives the pressure roller and the belt feeding roller to move via the transmission gears, so as to realize the synchronous movement of belt feeding and plate feeding.

[0005] During operation, the end of the sheet material is attached to the end of the machine head and slid along the machine head. At this time, the sheet material touches the touch switch, which is triggered, and the tape feeding unit starts feeding the tape. At the same time, the glue application unit rotates. After the sheet material passes through the glue application unit, the tape is glued. Simultaneously, the tape feeding unit feeds the edge banding tape into the edge banding tape guide, which guides the edge banding tape to the pressure roller side. At this time, as the glue application unit rotates, it transfers the sheet material towards the pressure roller side. When the sheet material approaches the pressure roller, the edge banding tape automatically adheres to the edge banding surface of the sheet material and keeps the sheet material close to the pressure roller. With the guidance of the pressure roller, the edge banding of the sheet material is completed. When the sheet material leaves the glue application unit, the glue application unit stops, the tape cutting unit operates to cut the edge banding tape, and the tape feeding unit stops at the same time, completing the edge banding of the sheet material.

[0006] Furthermore, the machine head can be used independently, installed on the feeding end of an automatic feeder, or installed on a manual feeding platform; it can adapt to various usage scenarios.

[0007] Furthermore, the drive motor is connected to the belt feed speed controller via a control console; the belt feed speed controller is located on the side of the machine head; the belt feed speed controller can control the speed of the drive motor, thereby realizing the belt feeding speed of the belt feeding unit.

[0008] Furthermore, the bottom of the machine head is provided with an air pipe interface for providing air to the whole machine and a power cord interface for providing power to the whole machine. The air pipe interface is connected to each air source port through a solenoid valve.

[0009] Furthermore, a manual handle is fixed to the machine head; the manual handle is equipped with a manual button for starting and stopping the drive motor; when the manual edge sealing mode is selected, the drive motor can be started and stopped by holding the manual handle and manually triggering the manual button, thereby achieving manual control of the edge sealing.

[0010] Furthermore, a glue-applying photoelectric switch is installed on the top of the machine head via a bracket; the detection end of the glue-applying photoelectric switch is directly opposite the glue-applying end of the glue-applying unit; when the board is removed from the glue-applying end of the glue-applying unit, the glue-applying photoelectric switch cannot detect the board, and it is assumed that the board has been removed from the glue-applying unit. The glue-applying unit stops, the tape-cutting unit operates to cut the edge-sealing tape, and the tape-feeding unit stops at the same time, thus completing the edge-sealing of the board.

[0011] Furthermore, the glue application unit includes a glue storage silo, the top of which is fixed with a top cover by bolts, a heater fixed to the top of the inner side of the glue storage silo, and an exhaust valve on the top of the top cover; a glue dispensing pressure plate is movably fitted into the bottom of the glue storage silo; the bottom of the glue dispensing pressure plate is fixed to the piston rod of the glue dispensing cylinder; the glue supply unit includes a roller groove formed outside the glue storage silo; a glue application shaft is rotatably mounted on the glue storage silo at the roller groove, and the glue application shaft is driven by an independent motor; a connecting flow channel is provided between the top of the glue storage silo and the roller groove; a glue scraper is provided on the side of the glue application shaft; the glue scraper is rotatably mounted to a sliding unit, and the mounting base of the sliding unit is fixed to the glue storage silo; the sliding end of the sliding unit is secured by a ball-shaped handle bolt. Driven by: When in use, open the top cover, put the glue block into the glue storage hopper, turn on the heater, and after the temperature reaches the set temperature, the glue dispensing cylinder will activate, driving the glue dispensing plate upward. At this time, the gas inside the glue storage hopper will be discharged through the exhaust valve, making the glue storage hopper a vacuum state. Then, close the exhaust valve. When feeding is needed, the glue dispensing cylinder will continue to move upward, and the glue locking cylinder will open the connecting channel, connecting the roller groove with the glue storage hopper. At this time, the hot melt fluid glue will be pressed from the glue storage hopper into the roller groove and coated onto the glue dispensing shaft as it rotates. Then, the sliding unit will be driven to slide through the ball-shaped handle bolt, causing the scraper shaft on the sliding unit to slide synchronously, thereby adjusting the gap between the glue dispensing shaft and the scraper shaft, and adjusting the thickness of the hot melt fluid glue on the surface of the glue dispensing shaft.

[0012] Furthermore, a discharge port is provided on the outer side of the bottom of the roller trough, and a recycling trough is provided on the front side of the machine head below the discharge port; when the PUR glue flows to the bottom of the roller trough, the PUR glue is sent into the recycling trough through the discharge port, and the PUR glue can be collected through the recycling trough.

[0013] Furthermore, the edge banding guide also includes a column, on which a height limiting rod slides through; the height limiting rod is positioned above two guide plates, and a bolt body is screwed to the end of the height limiting rod and tightened against the column. The bolt body can lock the height limiting rod and the column together. The height limiting rod slides on the column to adjust its height. After adjustment, the bolt body locks the position of the height limiting rod and the column.

[0014] Compared with existing technologies, the portable PUR edge banding machine for furniture panels of the present invention can perform PUR edge banding on-site through the machine head, ensuring that the edge banding is firmly adhered and has strong temperature resistance. The machine head adopts an integrated molding structure, which can be used for various edge banding scenarios and realize portable multi-combination PUR edge banding. That is, the machine head can be used alone, or combined with an automatic feeder for automatic feeding and edge banding, or it can be placed on a widened platform for manual board feeding and edge banding.

The glue application unit 3 is arranged side by side with the pressure roller 2 on the top of the machine head 1, and the glue application end of the glue application unit 3 is on the same plane as the front end of the pressure roller 2. Touch switch 4 is installed at the top front end of the machine head 1 and is located on the side away from the pressure roller 2; The touch switch 4, the glue application end of the glue application unit 3, and the pressure roller 2 are arranged on the edge sealing travel path of the board. During edge banding, the board first contacts the touch switch 4, then enters the glue application unit 3 for glue application, and finally the glued surface of the board is bonded to the edge banding tape by the pressure roller 2. The adhesive feeding unit 5 has a connecting channel between its discharge end and the inlet end of the coating unit 3. A locking cylinder 6 for locking the channel is provided outside the connecting channel. When coating, the piston rod of the locking cylinder 6 drives the locking head to disengage from the connecting channel. At this time, the adhesive feeding unit 5 feeds the coating unit 3. After the feeding is completed, the connecting channel can be re-locked by the locking cylinder 6. The control console 7 is fixed to the rear side of the machine head 1 by a support; The edge banding tape guide 8 consists of two guide plates forming a V-shaped structure. The output end of the edge banding tape guide 8 faces the pressure roller 2. The two guide plates form the edge banding tape guide 8. The edge banding tape enters between the two guide plates. Since the output ends of the two guide plates are narrowed, the edge banding tape can be centered and calibrated, so that the edge banding tape is accurately fed into the front side of the pressure roller 2, waiting for the glued board to bond with the edge banding tape. The tape feeding unit includes a tape feeding roller 9 disposed at the input end of the edge banding tape guide 8 and rotatably disposed at the top of the machine head 1. A tape feeding cylinder 10 is fixed to the side of the tape feeding roller 9. A slide block 11 is fixed to the telescopic end of the tape feeding cylinder 10. A driven roller 12 that is in contact with the tape feeding roller 9 is rotatably disposed at the end of the slide block 11. The edge banding tape roll on the external feeding tray is pulled into the space between the tape feeding roller 9 and the driven roller 12. When the edge banding tape needs to be fed, the slide block 11 is driven to slide by the tape feeding cylinder 10. The tape feeding cylinder 10 drives the driven roller 12 to move closer to the tape feeding roller 9, so that the tape feeding roller 9 and the driven roller 12 clamp the edge banding tape and transfer it with the rotation of the tape feeding roller 9, thereby feeding the edge banding tape into the input end of the edge banding tape guide 8, and thus feeding the edge banding tape into the side of the pressure roller 2. The tape cutting unit includes a tape cutting cylinder 13 fixed to the top of the machine head 1, and a cutter head 14 fixed to the telescopic end of the tape cutting cylinder 13. The tape cutting cylinder 13 is located behind the pressure roller 2. The cutter head 14 is positioned directly opposite the input end of the edge sealing tape guide 8 and the tape feeding unit. When the tape cutting unit is working, the tape cutting cylinder 13 drives the cutter head 14 forward, thereby allowing the cutter head 14 to enter the edge sealing tape transmission path. After the edge cutting is completed, the tape cutting cylinder 13 automatically resets. A drive motor 15 is fixed inside the head 1. The drive motor 15 is connected to the transmission gear 17 at the bottom of the drive pressure roller 2 and the feed roller 9 via a transmission chain 16. The drive motor 15 drives the transmission chain 16 to rotate, and the transmission chain 16 drives the pressure roller 2 and the feed roller 9 to move via the transmission gear 17, so as to realize the synchronous action of feeding the belt and feeding the plate.

[0024] During operation, the end of the board is attached to the end of the machine head 1 and slid along the machine head 1. At this time, the board touches the touch switch 4, which is triggered, and the tape feeding unit starts feeding the tape. At the same time, the glue application unit 3 rotates. After the board passes through the glue application unit 3, the board is glued. Meanwhile, the tape feeding unit feeds the edge sealing tape into the edge sealing tape guide 8, which guides the edge sealing tape to the side of the pressure roller 2. At this time, as the glue application unit 3 rotates, it transfers the board to the side of the pressure roller 2. When the board approaches the pressure roller 2, the edge sealing tape automatically adheres to the edge sealing surface of the board and keeps the board close to the pressure roller 2. With the guidance of the pressure roller 2, the edge sealing of the board is completed. When the board leaves the glue application unit 3, the glue application unit 3 stops, the tape cutting unit operates to cut the edge sealing tape, and the tape feeding unit stops at the same time, completing the edge sealing of the board.
