Description

Technical Field

[0001] This application relates to the technical field of wood composite board processing, and more particularly to a multi-layer wood composite board edge banding device. Background Technology

[0002] Multi-layer wood composite board is a type of engineered wood product. During processing, wood logs are typically rotary-cut into veneers or timber squares are sliced ​​into thin sheets, which are then glued together to form three or more layers of board-like material. It usually uses an odd number of veneer layers, with the grain direction of adjacent veneers perpendicular to each other. To improve product quality, the sides of the composite board are usually sealed after gluing.

[0003] In related technologies, since wood-based panels are mostly rectangular, edge banding equipment typically bands the parallel sides of the panel first, then turns it to band the other two sides. This process is cumbersome. When the edge banding strip is applied to the two sets of perpendicular sides of the composite panel, gaps appear at the corners of the composite panel, thus reducing the quality of the edge banding.

[0025] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0026] The multi-layer wood composite board edge banding device of this application embodiment will be described below with reference to the accompanying drawings.

[0027] like Figure 1-7As shown, the multi-layer wood composite board edge banding equipment of this application embodiment may include a fixed frame 10, multiple transverse conveying rollers 20, multiple drive components 30, multiple longitudinal conveying rollers 40, multiple edge banding components 60, a storage box 70, edge banding strips 80, and a support and steering component 90. It should be noted that stepper motors (not specifically shown in the figure) are respectively provided on the transverse conveying rollers 20 and the longitudinal conveying rollers 40 to drive their rotation; since this is prior art, it will not be described in detail here.

[0028] The bottom end of the fixed frame 10 and the fixed end of the drive assembly 30 are placed on the same horizontal plane. Multiple transverse conveying rollers 20 are rotatably mounted on the fixed frame 10, and multiple longitudinal conveying rollers 40 are rotatably mounted on the output ends of the drive assemblies 30, with the longitudinal conveying rollers 40 and transverse conveying rollers 20 perpendicular to each other. The longitudinal conveying rollers 40 and transverse conveying rollers 20 are used for planar conveying of the composite board 50 to be edge-sealed in different directions.

[0029] It should be noted that the drive component 30 described in this embodiment can be a hydraulic cylinder, which is connected to the power supply through a control switch to drive the longitudinal conveying roller 40 to move up and down. During the initial operation, the top of the longitudinal conveying roller 40 is lower than the top of the transverse conveying roller 20, so the initial conveying state of the composite board 50 is conveying on the transverse conveying roller 20.

[0030] The support steering assembly 90 is fixedly mounted on the fixed frame 10. The support steering assembly 90 is used to adjust the edge sealing assembly 60 according to the direction of the composite board 50 to be edge sealed during transportation and to seal the side of the composite board 50 to be edge sealed.

[0031] The edge sealing assembly 60 is rotatably mounted on the support steering assembly 90. The edge sealing assembly 60 includes a housing 601, a transmission mechanism 602, a reset mechanism 603, a pressure roller 604, and a corner edge sealing mechanism 605.

[0032] The housing 601 is rotatably mounted on the support steering assembly 90. The transmission mechanism 602 is located inside the housing 601. The corner sealing mechanism 605 is mounted on the transmission mechanism 602. A reset mechanism 603 is provided at the connection between the corner sealing mechanism 605 and the transmission mechanism 602. The corner sealing mechanism 605 is used to automatically flip and seal the corners of the composite board to be sealed by means of the reset mechanism 603. The pressure roller 604 is located inside the housing 601.

[0033] It should be noted that the transmission mechanism 602 may include a partition, a movable shaft, a transmission chain, a transmission sprocket, a first guide roller, a second guide roller, a driven sprocket, and a drive component (not specifically identified in the figure).

[0034] The partition divides the housing 601 into upper and lower cavities. The driving component is located in the lower cavity, as are the first and second guide rollers. A movable shaft is mounted on the housing 601, and the corner sealing mechanism 605 is movably mounted on it. It should be noted that the corner sealing mechanism 605 can open and close on the housing 601 via the movable shaft, allowing for corner sealing of the wood composite board 50 during transport. A reset mechanism 603 is provided at the connection between the corner sealing mechanism 605 and the movable shaft. The reset mechanism 603 can be a spiral spring, meaning the corner sealing mechanism 605 can be driven to rotate by the driving component and can also be flipped on the movable shaft via the reset mechanism 603. The corner sealing mechanism 605 is used to automatically flip and seal the corners of the composite board to be sealed via the reset mechanism 603. It should be noted that only one set of the corner sealing mechanism 605 can be provided on a set of sealing components 60, depending on the transport direction of the composite board 50.

[0035] The output end of the drive component is provided with a transmission sprocket, the driven sprocket is provided on the movable shaft, the transmission chain is meshed with the driven sprocket and the transmission sprocket, and the pressure roller 604 is provided inside the housing 601.

[0036] It should be noted that the driving component can be a motor, which is connected to a power source via a control switch. A reducer connects the motor's output to a rotating shaft (not specifically shown in the diagram). A transmission sprocket is mounted on the rotating shaft, and the sprocket drives the driven sprocket to rotate via a transmission chain. To achieve relative rotational movement between the two sets of movable shafts, two sets of driving components are required, each driven by a different control switch. When the driving components are not operating, the corner sealing mechanism 605 is in its initial state, with its angle as shown... Figure 2 The edge sealing mechanism 605, which does not contact the composite board 50, is shown.

[0037] The storage box 70 is detachably mounted on the edge sealing assembly 60. It should be noted that the storage box 70 may be a hollow box, and the edge sealing strip 80 is coiled and stored in the inner cavity of the storage box 70 by means of a shaft (not shown in the figure). The edge sealing strip 80 is disposed in the inner cavity of the storage box 70 and extends from the storage box 70 to the inner side of the edge sealing assembly 60.

[0038] Specifically, during edge banding, the composite board 50 is placed on the transverse conveyor roller 20 for transport. At this time, the edge banding assembly 60 seals both sides of the composite board 50. As it continues to be transported to the next work position, the drive assembly 30 pushes the longitudinal conveyor roller 40 upwards, lifting the composite board 50 and separating it from the transverse conveyor roller 20. The composite board 50 then changes its transport direction on the longitudinal conveyor roller 40. The edge banding assembly 60, pushed by the composite board 50, changes direction on the support and steering assembly 90 accordingly. Subsequently, during the longitudinal transport of the composite board 50, the edge banding assembly 60 seals the other sides of the composite board 50. The outer two sides are edge-sealed. The transmission mechanism 602 and the reset mechanism 603 in the edge-sealing assembly 60 cooperate to drive the corner edge-sealing mechanism 605 to rotate. When the composite board 50 is conveyed, the corner edge-sealing mechanism 605 rotates and attaches to the corner of the composite board 50 to seal the corner. Thus, when sealing the edge of the multi-layer wood composite board, a set of edge-sealing components in the parallel direction can seal the multi-layer wood composite board in different directions. As the wood composite board turns, the corner of the board is automatically sealed with glue to achieve seamless edge sealing and improve construction efficiency.

[0039] In one embodiment of this application, such as Figure 5 As shown, the corner sealing mechanism 605 may include a locking plate 6051, a limiting ring 6052, a partition plate 6053, and a pressing mechanism 6054.

[0040] The limiting ring 6052 is set on the outer wall of the locking plate 6051. The limiting ring 6052 is sleeved on the housing 61, which is then sleeved on the movable shaft in the transmission mechanism. The partition 6053 is set inside the locking plate 6051. The partition 6053 and the inner wall of the locking plate 6051 have through grooves (not specifically marked in the figure). The pressing mechanism 6054 is set on the inner wall of the locking plate 6051.

[0041] It should be noted that the edge banding strip 80 passes through the through groove left in the partition 6053 and the snap-fit ​​plate 6051 and is pressed and fixed by the pressing mechanism 6054. When sealing the edges of the composite board 50, it can be done through the area at "B" on the snap-fit ​​plate 6051 (such as...). Figure 5 As shown in the figure, the edges of the composite board 50 are sealed. The position of the partition 6053 should be such that it will not touch the edges of the composite board 50 when the snap plate 6051 is flipped. It can be designed according to the actual situation and is not limited here.

[0042] In one embodiment of this application, such as Figure 6 As shown, the pressing mechanism 6054 may include a groove 60541, a pressing plate 60542, a limiting hole 60543, a clamping plate 60544, and a fastening screw 60545.

[0043] The groove 60541 is formed on the locking plate 6051, the pressing plate 60542 is set in the groove 60541, the limiting hole 60543 is formed on the pressing plate 60542, the locking plate 60544 is set on the bottom wall of the pressing plate 60542 and the locking plate 60544 is locked in the groove 60541, and the fastening screw 60545 passes through the limiting hole 60543 and is threaded into the groove 60541.

[0044] It should be noted that the edge banding strip 80 only needs to be attached to one end in the groove 60541, and then the pressing plate 60542 is pressed onto the groove 60541. The edge banding strip 80 is fixed by passing the fastening screw 60545 through the limiting hole 60543 and threaded into the groove 60541. During the conveying process of the wood composite board 50, the composite board is sealed. After the sealing is completed, only the excess strip needs to be cut off.

[0045] To clearly illustrate the previous embodiment, in one embodiment of this application, as follows: Figure 6 As shown, a countersunk hole is left in the limiting hole 60543, and a head is left on the top wall of the fastening screw 60545. The head is connected to the countersunk hole with a clearance fit, and the height of the head is the same as the depth of the countersunk hole. The top wall of the head is provided with an internal hexagonal groove. When the pressing plate 60542 is embedded in the groove 60541, the surface is flat, and the top wall of the fastening screw 60545 is flush with the top surface of the pressing plate 60542.

[0046] In one embodiment of this application, such as Figure 4 As shown, the steering support assembly 90 may include a base 901, a pivot 902, and a second reset mechanism 903.

[0047] The base 901 is mounted on the fixed frame 10, and the rotating shaft 902 is rotatably mounted on the base 901. It should be noted that the rotating shaft 902 can be adjusted in height within the base 901. Specifically, a movable plate (not shown in the figure) is provided within the cavity of the base 901. The top wall of the movable plate is connected to the rotating shaft 902 via a bearing (not shown in the figure), and the rotating shaft 902 is connected to the edge sealing assembly 60. A second reset mechanism 903, which is a reset spring, is provided at the connection point between the rotating shaft 902 and the edge sealing assembly 60.

[0048] It should be noted that the base 901 can be adjusted according to the length and width of the composite board 50 to be edge-sealed (the adjustment method of the base 901 on the fixing frame 10 is not limited and can be determined according to the actual situation). For example, the base 901 is installed on the fixing frame 10 through a telescopic adjustable connecting rod, so that the edge-sealing assembly 60 can meet the composite board 50 of different lengths and widths. The edge-sealing assembly 60 can be automatically flipped through the rotating shaft 902 and the second reset mechanism 903, and automatically reset when no force is applied.

[0049] Specifically, when the multi-layer wood composite board 50 is edge-banded, the edge-banding strip 80 is first placed in the inner cavity of the storage box 70, and one end of the edge-banding strip 80 is passed through the first guide roller and the second guide roller, then passes through the surface of the pressure roller 604 and is finally fixed in the corner edge-banding mechanism 605 by the pressing mechanism 6054.

[0050] The wood composite board 50 is placed on the transverse conveyor roller 20 and conveyed from "④" to "③". At this time, the edge sealing mechanism 605 at position "①" of the edge sealing assembly 60 rotates through the drive component. The locking plate 6051, under the force of the reset mechanism 603, first passes through one edge of the composite board 50, sealing one edge of the composite board 50. Then, during the conveying process, it flips and adheres to the side of the composite board 50. At this time, the reset mechanism 603 undergoes elastic deformation. Under the relative force between the locking plate 6051 and the composite board 50, the locking plate 6051 cannot flip and can only adhere tightly to the side of the composite board 50. At the same time, the drive component in each set of edge sealing assemblies 60 is controlled by different drive switches to avoid repeated edge sealing. The edge sealing strip 80 can be pressed onto the side of one set of two sides of the composite board 50 by the pressure roller 604.

[0051] When sealing the other two sides of the composite board 50, the composite board 50 with one side edge-sealed has come into contact with the edge-sealing assembly 60 at positions "② and ③". At this time, the edge-sealing mechanism 605 on the edge-sealing assembly 60 at positions "② and ③" is in its initial state and does not come into contact with the composite board 50. The drive assembly 30 pushes the longitudinal conveyor roller 40 upward, thus lifting the composite board 50 and separating it from the transverse conveyor roller 20. Simultaneously, the edge-sealing assembly 60 moves upward on the support steering assembly 90. At this time, the composite board 50 is conveyed in a different direction on the longitudinal conveyor roller 40. During the change of direction, the composite board 50 simultaneously drives the edge-sealing assembly 60 to rotate on the support steering assembly 90. At this time, the corner sealing mechanism 605 is disengaged from the composite board 50 and is flipped by the reset mechanism 603, so that the inner wall of the corner sealing mechanism 605 contacts the other corner of the composite board 50, sealing the other corner of the composite board 50, and completing the sealing of the other two sides of the composite board 50 during continuous conveying.

[0052] Similarly, when the wood composite board 50 is placed on the transverse conveyor roller 20 and conveyed from "③" to "④", it is only necessary to fix the edge sealing strip 80 on another set of corner edge sealing mechanism 605 on the same set of edge sealing components 60, so as to achieve the purpose of multi-directional synchronous edge sealing construction.

[0053] In one embodiment of this application, such as Figure 7As shown, the edge sealing assembly 60 may also include a guide heating assembly 606, which includes an outer guide roller 6061, a base 6062, and an electric heating rod 6063.

[0054] The base 6062 is disposed inside the housing 601; the electric heating rod 6063 is fixedly disposed on the base 6062; the outer guide roller 6061 is rotatably sleeved on the electric heating rod 6063, the center of the outer guide roller 6061 and the pressure roller 604 are located on the same horizontal line, and the outer guide roller 6061 and the pressure roller 604 have the same outer diameter.

[0055] Specifically, a guide heating component 606 is provided near the pressure roller 604. The edge sealing strip 80 to be bonded can be heated by an electric heating rod 6063, which softens the edge sealing strip 80 and makes it easier to bond.

[0056] In summary, the multi-layer wood composite board edge banding equipment of this application embodiment can perform edge banding on multi-layer wood composite boards in different directions by using a set of edge banding components in the parallel direction. Furthermore, it can automatically seal the edges of the boards as they turn, achieving seamless edge banding and improving construction efficiency.

[0057] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
