Technical Field
The invention relates to the field of woodworking plate processing, in particular to a furniture woodworking plate gluing and edge covering device and method.
Background
Furniture such as a wooden wardrobe and the like is manufactured by taking solid wood sawn timber or a solid wood board as a base material, and the surface of the furniture is subjected to coating treatment; or furniture which is coated after the substrate is coated by a solid wood veneer or a veneer (veneer). During the processing of the wooden wardrobe, the board needs to be glued and covered with edges, namely, strip edge sealing materials such as thin strips, melamine resin decorative strips, plastic film PVC strips and the like are glued and pressed on the edges of the board, so that the periphery of the board is sealed. The appearance quality of the furniture can be well improved through gluing and edge covering, corner damage and facing layer lifting or peeling of the furniture in the transportation and use processes are avoided, and meanwhile, the effects of preventing water, sealing the release of harmful gas and reducing deformation and cracking can be achieved. The gluing and edge covering operation is an important process in the manufacturing process of the plate-type furniture, and the quality of the gluing and edge covering directly influences the quality, price and grade of the product. Therefore, the gluing and edge covering quality is very important for the processing of furniture such as wooden wardrobes and the like.
The prior art has the following defects: 1. when the plate is pre-milled, the side edge of the plate is firstly attached to a fixed backup plate to align the milling position of the side edge of the plate with the milling mechanism, and then the milling mechanism mills the side edge of the plate; the position of the backup plate is fixed relative to the milling mechanism, namely the distance from the milling position of the plate to the side edge of the plate is fixed, and the milling mechanism can only mill the plate at a fixed distance from the side edge of the plate; when the milling position of the plate needs to be changed, the backup plate needs to be installed at a different position again, so that the adaptability of the pre-milling device is reduced. 2. When the side edge of the plate is glued, the air cylinder is adopted to push the glue extruding rubber roller to move to a fixed position which is contacted with the side edge of the plate so as to glue the side edge of the plate; the distances from different positions of the side edge of the plate to the fixed glue extruding rubber roll are different due to the fact that the surface flatness of the side edge of the plate is poor only through rough milling, the plate can partially deform in the processing process and the like; when the distance from the side edge part of the plate to the glue extruding rubber roll is far, the side edge of the plate is not in contact with the surface of the glue extruding rubber roll, so that the corresponding position is not fully glued, and the gluing quality of the side edge of the plate is influenced. 3. When the glue extruding mechanism is used for supplying glue, firstly, the glue in the glue pool is pushed by air pressure to move to the position of the valve along the flow channel, and then the air cylinder drives the valve to be opened to supply the glue to the glue extruding mechanism; when a certain amount of glue is supplied to the valve, the valve needs to be opened and then closed, and the glue flowing between the opening and the closing of the valve is the amount of the glue to be conveyed; the opening and closing of the valve need two steps, and the time needed in the middle is longer; meanwhile, the stroke of the cylinder is large, and the range of opening and closing the valve is large, so that the quantity of glue conveyed once when the valve is opened and closed is large, and the accurate glue supply of a small quantity of glue supplied once by a glue supply mechanism is not facilitated.

The furniture woodworking plate gluing and edge covering equipment and method adopting the technical scheme have the advantages that:
1. by arranging a backup plate mechanism; when the plate is fed, adjusting a backup plate screw rod to rotate to drive a backup plate to move to a set plate milling position; and feeding the plate to the plate conveying device, and attaching the side edge of the plate to the plate leaning surface. When the adjusting backup plate screw rod rotates, the backup plate surface can be driven to move; when the milling position of the plate needs to be changed, the backup plate surface can be driven to move relative to the milling mechanism by adjusting the backup plate screw rod, so that the milling position of the plate is changed; and then the problem that the milling position cannot be changed when the backup plate is fixed is avoided, and the adaptability of the pre-milling device is improved.
2. By arranging the glue extruding guide post, the glue extruding spring and the glue extruding head; after the plate moves to the glue applying station, the glue extruding spring drives the glue extruding head to move to a position where the glue extruding head is contacted with the side edge of the plate along the glue extruding guide post; the glue is attached to the outer surface of the glue extruding rubber roll along the glue extruding slideway through the glue extruding door; the plate conveying device drives the plate to move, and the glue attached to the outer surface of the glue extruding rubber roller is contacted with different positions of the side edge of the plate to coat the glue on the side edge of the plate to finish the glue extruding process of the plate. When the glue extruding spring drives the glue extruding head to contact with the side edge of the plate, pressure can be always provided for the glue extruding head; when the glue extruding head moves on the deformed side edge surface of the plate, the glue extruding head can always contact with different positions of the side edge surface of the plate under the elastic force of the glue extruding spring; the side edge of the plate is subjected to conditions that the surface flatness of the side edge of the plate is poor only by rough milling and the plate can partially deform in the processing process: when the side surface of the plate is sunken, the glue extruding spring extends and provides pressure for the glue extruding head to enable the glue extruding head to be tightly attached to the sunken position of the side surface of the plate; when the side surface of the plate is convex, the glue extruding spring contracts and provides pressure for the glue extruding head to enable the glue extruding head to cling to the convex part of the side surface of the plate; thereby avoiding the problem that the glue is not sufficiently applied when the glue extruding head can only apply glue at a fixed position, and improving the glue applying quality of the side edge of the plate.
3. By arranging the glue pushing assembly; after the glue is fed to the corresponding cavity of the glue pushing base, the pneumatic motor rotates to drive the glue pushing screw rod connected with the pneumatic motor to rotate, and the glue pushing screw rod rotates to drive the glue in the corresponding cavity of the glue pushing base to move to the flow guide hole along the spiral part of the glue pushing screw rod; the glue flows to the feed inlet of the glue extruding mechanism along the glue outlet flow guide pipe through the flow guide holes to complete the glue supply process of the plate. When the glue is supplied by the glue pushing screw, the rotation of the spiral part of the glue pushing screw is converted into the linear motion of the glue, and the glue can be discharged only by rotating the glue pushing screw in one step; meanwhile, the rotation precision of the pneumatic motor is high, the angle for driving the glue pushing screw to rotate once is small when the pneumatic motor rotates, namely the distance for converting the linear motion of the glue by rotating the spiral part of the glue pushing screw is smaller than the stroke of the air cylinder; the glue quantity pushed out by the glue pushing screw is smaller than that pushed out by driving the valve to open by the stroke of the cylinder, so that the accuracy of the glue supply mechanism is ensured.
