Description

Technical Field

[0001] This utility model relates to the field of edge banding technology for plywood, and in particular to an edge banding device for plywood edge treatment. Background Technology

[0002] Plywood is a type of board made by gluing together multiple layers of wood. It is a structural board made by cross-laminating, gluing, and hot-pressing three or more layers of wood. Plywood edge banding refers to the treatment of the edges of the plywood to enhance its appearance, durability, and moisture resistance.

[0003] By comparing a wood board edge banding device with patent publication number CN222178118U, it was found that in this solution, the worker pushes the frame board to slide along the side of the wood board, thereby attaching the edge banding strip to the side of the wood board. This not only improves the edge banding efficiency, but also saves production costs compared with bulky and complex edge banding equipment. However, after applying glue to the edge of the board, the glue may be squeezed out when pressing the edge banding, causing glue overflow. This glue will not only affect the appearance of the board, but also cause dust and other impurities to adhere to the edge of the board, reducing the quality of the edge banding.

An extrusion plate 204 is slidably installed inside the adhesive application tube 202. A pressing cylinder 203 is located between the extrusion plate 204 and the rear connecting frame 201. A glue collection tank 206 is located behind the rear connecting frame 201. A suction pump 207 is located below the glue collection tank 206. A glue outlet pipe is connected between the suction pump 207 and the adhesive application tube 202. A solenoid valve is installed at the end of the glue outlet pipe near the adhesive application tube 202. A solenoid valve is installed at the upper end of the extrusion plate 204 near... A baffle 205 is fixed at the glue outlet, and a telescopic cylinder 208 is provided on the front side of the glue application tube 202. A spreading plate 209 is provided at the lower end of the telescopic cylinder 208. The spreading plate 209 is made of silicone. The edge sealing structure is used to seal the edge of the plywood. Then, a cleaning structure is used to clean and cut the glue squeezed out during the edge sealing of the plywood edge, including the excess edge sealing strip 212, to ensure that the edge sealing strip 212 matches the edge of the plywood. At the same time, it avoids the residual glue adhering to dust and other impurities, which would cause the plywood edge to turn black, affecting the later use and aesthetics, thus improving the quality of edge sealing.

[0035] Working principle: First, the board to be edge-sealed is placed between multiple conveyor rollers 304. The telescopic hydraulic cylinder 303 is driven to push two sliding plates 302 closer to the board, causing the multiple conveyor rollers 304 to clamp the sides of the board. Then, the conveyor motor 305 drives the conveyor rollers 304 to rotate and convey the board forward. First, the board moves to the bottom of the glue application tube 202. The pressing cylinder 203 pushes the extrusion plate 204 up and down, and the suction pump 207 continuously feeds glue into the glue application tube 202, thereby squeezing the glue inside the glue application tube 202 downward, so that the glue falls on the edge of the board in a dotted form. Then, the telescopic cylinder 208 drives the spreading plate 209 to move down, so that the bottom of the spreading plate 209 contacts the edge of the board. When the board moves forward, the spreading plate 209 flattens the glue, and the dotted glue is evenly applied to the edge of the board.

[0036] After the glue is applied, the board continues to move forward until it is below the pressure roller 217. The lifting motor 215 drives the lead screw 214 to rotate, which in turn drives the lifting frame 216 to move down, which in turn drives the pressure roller 217 to move down. The pressure roller 217 then drives the edge banding strip 212 to move down, so that the edge banding strip 212 is in contact with the edge of the board. The pressure roller 217 then applies downward pressure to the edge banding strip 212, which makes the edge banding strip 212 fit tightly with the edge of the board, and the two are firmly adhered together.

[0037] Then, the edge-banded board continues to move forward until it reaches the two scrapers 221. The two moving motors 224 drive the eccentric disk 222 to rotate, and the rotating plate 223 drives the sliding seat 220 to move back and forth, which in turn drives the two scrapers 221 to move back and forth. This allows the two scrapers 221 to scrape and cut off the residual glue and excess edge banding strip 212 on the edge of the edge-banded board, ensuring that the edge banding strip 212 matches the edge of the board. At the same time, it prevents residual glue from adhering to dust and other impurities, which would cause the plywood edge to turn black, affecting its later use and appearance. Then, the two rotating motors 228 are driven, and the two gears 227 mesh with each other, thereby driving the two vertically distributed rotating rollers 226 to rotate in opposite directions. In conjunction with the spiral protrusions on the surface of the rotating rollers 226, the excess edge banding strip 212 is pulled away from the board, breaking off this excess material and reducing its impact on the movement of the board, thus improving the quality of the edge banding.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
