Description
Technical Field
[0001] This invention specifically relates to an automatic edge banding and trimming machine for edge banding of decorative panels, belonging to the field of edge banding equipment processing technology for panels. Background Technology
[0002] An edge banding machine is a device used to trim and band the edges of various types of board-shaped wood, such as plywood, solid wood boards, particleboard, and door panels. For example, Chinese Patent Publication No. CN120245160A discloses a board edge banding device for graphic design, including a back panel, a guide assembly, a feeding assembly, and a cutting assembly. This invention involves the front of the back panel being attached to the back of the board, the guide assembly being attached to the front of the board, and adhesive stored in an adhesive storage tank dripping onto a coating wheel through a supply pipe. The coating wheel rotates under friction, evenly distributing the adhesive. The edge banding tape is evenly coated on the top of the board. Under the pressure of the rollers, the edge banding tape is adhered to the board for edge sealing. Traditional edge banding machines mostly use EVA (hot melt adhesive) for edge sealing. However, the amount of adhesive used for EVA is three times that of PUR. At the same time, due to the larger amount of adhesive used, the EVA glue lines are more obvious after edge sealing, affecting the appearance. EVA glue is inferior to PUR glue in terms of waterproof and moisture resistance, high temperature resistance and service life. When EVA edge sealing is heated at high temperature, it will emit a pungent odor, which will have an adverse impact on the environment. In addition, the edge sealing is uneven after completion. Summary of the Invention
[0003] To address the aforementioned issues, this invention proposes an automatic edge banding and trimming machine for edge banding decorative panels. This machine can firmly adhere the edge banding tape to the decorative panels, ensuring a smooth transition between the edge banding tape and the edge of the decorative panels after adhesion.
[0004] The present invention relates to an automatic edge banding and trimming integrated machine for edge banding of decorative panels, comprising a machine base, a feeding unit installed on one side of the machine base along its length, an edge banding and trimming unit installed on the opposite side of the feeding unit, and a control console for overall machine control fixed on the machine base; the edge banding and trimming unit is sequentially arranged from input to output as an edge banding placement unit, a vacuum gluing unit, a gluing unit, an edge trimming unit, an edge scraping unit, and a polishing unit; an edge banding tape roll is placed on the edge banding placement unit; the vacuum gluing unit is connected to the gluing unit; the gluing end of the gluing unit, the edge trimming end of the edge trimming unit, the edge scraping end of the edge scraping unit, and the polishing end of the polishing unit are on the same straight line; after the edge banding tape roll is roller coated by the gluing unit, it is adhered to the edge banding position of the decorative panel, so that the edge banding tape roll and the decorative panel are pressed together as one.
[0005] The decorative panels are fed onto the machine and then into the feeding end of the feeding unit. They are then conveyed backward by the feeding unit. Simultaneously, the edge banding tape on the edge banding placement unit is fed into the gluing unit. The vacuum gluing unit delivers molten PUR adhesive into the gluing unit, which applies adhesive to the surface of the edge banding tape. The glued edge banding tape adheres tightly to the panels conveyed by the feeding unit, completing the edge banding operation. The edge-banded decorative panels continue to be conveyed forward by the feeding unit and are then trimmed by the trimming unit, aligning the top and bottom edges of the edge banding tape with the top and bottom edges of the panels and smoothing the edges of the edge banding tape and panels. Next, the scraping unit scrapes the trimmed areas to clean away any remaining waste edge banding. Finally, the polishing unit polishes the top and bottom edges of the edge banding tape, ensuring a smooth transition between the edges of the edge banding tape and the decorative panels. Finally, the edge-banded panels are conveyed out through the feeding unit.
[0006] Furthermore, the edge banding placement assembly unit includes a main board, on the rear side of which an edge banding pressure tube is installed via pressure tube fixing bolts; horizontal guide rollers and vertical guide rollers are installed on the top sides of the main board via support plates; an edge banding roll is provided between the main board and the edge banding pressure tube; and multiple edge banding anti-deviation rollers are provided on the main board outside the edge banding roll.
[0007] The edge banding placement unit is used to store the edge banding roll. The edge banding roll is movably clamped onto the main board by the edge banding pressure tube. The edge banding anti-deviation roller on the main board forms an outer enclosure for the edge banding roll, which can prevent the edge banding roll from deviating during traction and discharge. When the edge banding roll is traction and discharge, it is centered and corrected by the horizontal guide roller and the vertical guide roller in sequence, and finally it is guided to the glue application unit.
[0008] The vacuum glue dispensing unit includes a glue storage chamber, a heating tube installed at the bottom of the glue storage chamber, a glue outlet pipe installed at the top of the glue storage chamber, a glue dispensing cylinder fixed at the top of the glue storage chamber via a support, a glue dispensing pressure plate installed at the top of the inner side of the glue storage chamber, and the glue dispensing pressure plate being fixed to the piston rod of the glue dispensing cylinder; an exhaust rod is slidably mounted on the support, an exhaust valve is fixed at the top of the exhaust rod, and the bottom of the exhaust rod is connected to the inside of the glue storage chamber via the glue dispensing pressure plate;
[0009] When the vacuum dispensing assembly unit is working, the glue block is placed into the glue storage bin, the bottom heating tube is turned on, and after the temperature reaches the set temperature, the dispensing cylinder is activated, driving the dispensing pressure plate to press down. At this time, the gas inside the glue storage bin is discharged through the exhaust rod and exhaust valve, making the glue storage bin a vacuum state. Then, the exhaust valve is closed, the dispensing cylinder continues to press down, and the hot melt fluid glue is discharged from the glue outlet and enters the dispensing assembly unit.

[0011] When the glue application unit is working, the vacuum glue application unit injects hot melt fluid glue into the glue inlet and then sends it into the glue application tube seat. Next, the hot melt fluid is distributed to the glue application shaft through the glue distribution groove. The glue application shaft is driven to rotate by the glue application motor, thereby completing the coating of hot melt fluid on the glue application shaft. When the edge sealing tape passes through the glue application shaft, the glue application shaft can coat the edge sealing tape with hot melt fluid. The photoelectric detection switch monitors the glue overflow port in real time. When the photoelectric detection switch detects that there is no glue at the glue overflow port, the pneumatic valve opens, and the vacuum glue application unit replenishes glue to the glue application tube seat. After the glue replenishment is set for a set time, the pneumatic valve is closed, and the glue replenishment work is completed.

[0013] When the trimming assembly unit is working, after the edge banding tape and decorative panels are pasted and sealed, the decorative panels enter the trimming assembly unit. The starting position of the lower trimming motor is in a low position, so that the lower trimming knife is in the lower trimming position, and the corresponding trimming cylinder is in the extended state. Then, the lower edge trimming work is carried out. The lower trimming knife continuously trims the lower edge of the panel. When the trimming work reaches the end of the panel, the cylinder retracts, the lower trimming knife moves upward, and cuts off the excess edge banding tape protruding from the end of the panel. The upper trimming motor synchronously drives the upper trimming knife to trim the upper edge of the panel. The extension or retraction stroke of the trimming cylinder can be precisely adjusted by the trimming adjustment handle, so as to precisely control the travel position of the upper and lower trimming knives.
