Description

Technical Field

[0001] This utility model relates to the technical field of laminated plywood processing, and in particular to an edge grinding device for laminated plywood. Background Technology

[0002] Edge grinding equipment for laminated plywood is a type of mechanical equipment specifically used for grinding, chamfering, or polishing the edges of plywood whose surfaces have been covered with decorative films (such as melamine film, PVC film, etc.).

[0003] In related technologies, existing edge grinding devices for laminated plywood mainly adopt two types of structures: one is manual grinding by workers using tools such as hand-held angle grinders; the other is using conveyor equipment or worktables with fixed grinding heads. In practical applications, the latter has a simple clamping method, generally relying on manual support or simple baffles, which cannot reliably fix the board and has poor adaptability. This leads to the board being prone to displacement or vibration during grinding, resulting in quality problems such as uneven grinding, crooked edges, or scratches on the surface. At the same time, the grinding stroke is often limited, and it is not possible to grind long boards completely in one go, leaving joint marks and resulting in poor consistency of the ground surface. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a grinding device for coated plywood, which utilizes a first connecting block, a second connecting block and a movable grinding mechanism installed between them to achieve reliable positioning and clamping of the board, flexible size adaptation and stability of the grinding process, and effectively improves the consistency of the board processing quality.

[0006] To achieve the above objectives, this utility model proposes an edge grinding device for laminated plywood, comprising a lifting frame, two connecting mechanisms, a first connecting block, a second connecting block, two positioning mechanisms, and a movable grinding mechanism. The first connecting block and the second connecting block are movably connected to the lifting frame via the two connecting mechanisms. The two positioning mechanisms are respectively disposed on the first connecting block and the second connecting block. The movable grinding mechanism includes a driving component, an adjusting plate, and a grinding component. The adjusting plate is movably connected between the two positioning mechanisms via the driving component, and the grinding component is disposed on the adjusting plate.

[0007] In addition, the edge grinding device for coated plywood proposed above according to this utility model may also have the following additional technical features: Specifically, the driving assembly includes two symmetrically arranged limiting rods, a first stud, and a first driving device. One end of the two symmetrically arranged limiting rods is disposed on the first connecting block, and the other end of the two symmetrically arranged limiting rods is movably connected to the second connecting block and passes through the second connecting block. Nuts are provided on the two symmetrically arranged limiting rods. The first stud is rotatably connected to the first connecting block through the first driving device, and the end of the first stud away from the first driving device passes through the second connecting block.

[0008] Specifically, the grinding assembly includes two sets of symmetrically arranged first connecting plates, two sets of symmetrically arranged drive rollers, a second drive device, and a sanding belt. The two sets of symmetrically arranged first connecting plates are disposed on the adjusting plate, the two sets of symmetrically arranged drive rollers are rotatably connected to the two sets of symmetrically arranged first connecting plates, the sanding belt is wound around the two sets of symmetrically arranged drive rollers, and the second drive device is disposed on the first connecting plate and connected to the end of one of the drive rollers.

[0009] Specifically, the connecting mechanism includes a sliding sleeve, a third driving device, and a locking screw. The sliding sleeve is movably connected to the lifting frame, the locking screw is movably connected to the sliding sleeve and threadedly connected to the sliding sleeve, and the third driving device is disposed on the sliding sleeve and located below the sliding sleeve, and is connected to the first connecting block and the second connecting block respectively.

[0010] Specifically, the positioning mechanism includes a second connecting plate, two symmetrically arranged second limiting posts, a second stud, and a clamping plate. The second connecting plate is respectively disposed on the first connecting block and the second connecting block. The clamping plate is movably connected to the second connecting plate through the second stud. The two symmetrically arranged second limiting posts are disposed on the clamping plate and penetrate through the second connecting plate.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The edge grinding device for coated plywood of this utility model adopts an adjustable mechanical structure. Through the combination design of the first connecting block, the second connecting block and the movable grinding mechanism erected between them, it can clamp boards of different lengths. At the same time, the positioning mechanisms on both sides actively and stably clamp the adjacent edges of the board grinding surface, improve the stability of the board and grinding components during the grinding process, and ensure the grinding accuracy and surface quality. With the extension of the positioning mechanisms on both sides, the stroke of its moving grinding mechanism can perform a complete and seamless grinding of the edge of the board in one go, avoiding the joint marks of segmented grinding and significantly improving the consistency of product quality.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown 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 the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The edge-grinding device for laminated plywood according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0017] like Figures 1-4 As shown, the edge grinding device for laminated plywood according to this utility model embodiment includes a hoisting frame 1, two connecting mechanisms 2, a first connecting block 3, a second connecting block 4, two positioning mechanisms 5, and a moving grinding mechanism 6.

[0018] The first connecting block 3 and the second connecting block 4 are movably connected to the hoisting frame 1 through two connecting mechanisms 2, and two positioning mechanisms 5 are respectively set on the first connecting block 3 and the second connecting block 4.

[0019] It should be noted that the hoisting frame 1 described in this embodiment is suspended and installed using through holes at both ends. The two connecting mechanisms 2 drive the first connecting block 3, the second connecting block 4, the two positioning mechanisms 5 and the moving grinding mechanism 6 to move up and down stably for adjustment. The first connecting block 3 and the second connecting block 4 can move synchronously or be adjusted independently through the two connecting mechanisms 2 to change the distance between the first connecting block 3 and the second connecting block 4.

[0020] The mobile polishing mechanism 6 includes a drive assembly 61, an adjustment plate 62, and a polishing assembly 63.

[0021] The adjusting plate 62 is movably connected between the two positioning mechanisms 5 via the driving component 61, and the grinding component 63 is disposed on the adjusting plate 62.

[0022] It should be noted that the drive component 61 described in this embodiment is used to support the adjustment plate 62, and the movement adjustment of the grinding component 63 is realized by driving the moving plate to move between the first connecting block 3 and the second connecting block 4.

[0023] Specifically, during the actual grinding process, the relevant personnel install the device by screwing a long threaded screw into the through holes at both ends of the hoisting frame 1 to suspend the device. In the initial state, the locking screw 23 is loose, and the two sliding sleeves 21 can move synchronously along the length of the hoisting frame 1, or rotate the nut 6111 in the forward direction to bring the second connecting block 4 and the positioning mechanism 5 on the same side closer to the second connecting block 4. Under the movement limit action of the sliding sleeve 21, the adjustment stability of the first connecting block 3 and the second connecting block 4 is improved, and the third drive device 22 is in a retracted state. After the locking screw 23 is fixed, the positions of the two sliding sleeves 21 are fixed, realizing the initial position fixation of the first connecting block 3 and the second connecting block 4, and making the grinding surface of the laminated plywood between the first connecting block 3 and the second connecting block 4, with a margin between the two sides of the board and the first connecting block 3 and the second connecting block 4 respectively.

[0024] Before sanding the board, when laying the board, it is necessary to position the stacked boards one by one, so that the side of the board with the adjacent sanding surface is placed close to the first connecting block 3 first. After stacking, the second stud 53 on that side can be rotated to extend the clamping plate 54 and act on one side of the sanding surface of the board. Using the clamping plate on one side of the first connecting block 3 as a reference, the position of the clamping plate on the other side is adjusted to achieve clamping of the adjacent surfaces on both sides of the sanding surface of the board and to position the board at the same time. At this time, the travel of the sanding component 63 is longer than the length of the sanding surface of the board.

[0025] During grinding, the second drive device 633 is driven to rotate, which in turn drives one of the drive rollers 632 to rotate. Under the connection of the sanding belt 634, the other drive roller 632 rotates synchronously and contacts the grinding surface of the board to achieve grinding. At the same time, the first drive device 613 is driven to rotate, and the first stud 612 moves horizontally under the limiting action of two symmetrically arranged first limiting rods 611 to achieve grinding of the board.

[0026] In one embodiment of this utility model, such as Figures 1-3 As shown, the drive assembly 61 includes two symmetrically arranged limiting rods 611, a first stud 612, and a first drive device 613.

[0027] Among them, one end of the two symmetrically arranged limiting rods 611 is set on the first connecting block 3, and the other end of the two symmetrically arranged limiting rods 611 is movably connected to the second connecting block 4 and passes through the second connecting block 4. Nuts 6111 are provided on the two symmetrically arranged limiting rods 611. The first stud 612 is rotatably connected to the first connecting block 3 through the first driving device 613, and the end of the first stud 612 away from the first driving device 613 passes through the second connecting block 4.

[0028] It should be noted that the first driving device 613 proposed in the above embodiment adopts a rotary motor. The output end of the rotary motor is connected to the end of the first stud 612, driving the first stud 612 to rotate synchronously. Under the sliding limit action of two symmetrically arranged limiting rods 611, the adjusting plate 62 moves and adjusts along the axial direction of the first stud 612.

[0029] In one embodiment of this utility model, such as Figures 1-3 As shown, the grinding assembly 63 includes two sets of symmetrically arranged first connecting plates 631, two sets of symmetrically arranged drive rollers 632, a second drive device 633, and a sanding belt 634.

[0030] Two sets of symmetrically arranged first connecting plates 631 are mounted on the adjusting plate 62, two sets of symmetrically arranged drive rollers 632 are rotatably connected to the two sets of symmetrically arranged first connecting plates 631 respectively, a sanding belt 634 is wound around the two sets of symmetrically arranged drive rollers 632, and a second driving device 633 is mounted on the first connecting plate 631 and connected to the end of one of the drive rollers 632.

[0031] It should be noted that the second driving device 633 proposed in the above embodiment adopts a rotary motor. The output end of the second driving device 633 is connected to the end of one of the driving rollers 632, driving it to rotate. The synchronous rotation is achieved by using the wound sanding belt 634, which increases the grinding stability. The distance between the two driving rollers 632 is appropriate and should not be too long to avoid the sanding belt 634 from being deformed inward, resulting in uneven grinding and severe local wear of the sanding belt 634.

[0032] In one embodiment of this utility model, such as Figures 1-4 As shown, the connecting mechanism 2 includes a sliding sleeve 21, a third driving device 22, and a locking screw 23.

[0033] The sliding sleeve 21 is movably connected to the lifting frame 1, the locking screw 23 is movably connected to the sliding sleeve 21 and threadedly connected to the sliding sleeve 21, and the third driving device 22 is disposed on the sliding sleeve 21 and located below the sliding sleeve 21, and is connected to the first connecting block 3 and the second connecting block 4 respectively.

[0034] It should be noted that the third drive device 22 described in this embodiment is a cylinder. The fixed end of the cylinder is slidably connected to the lifting frame 1 through the sliding sleeve 21, and the position of the sliding sleeve 21 is fixed by the locking screw 23 connected by the side wall thread. The telescopic end of the cylinder is connected to the first connecting block 3 and the second connecting block 4 respectively. By adjusting the height of the first connecting block 3, the second connecting block 4, the two positioning mechanisms 5 and the moving grinding mechanism 6, the stacked plates can be ground layer by layer from top to bottom.

[0035] In one embodiment of this utility model, such as Figures 1-3 As shown, the positioning mechanism 5 includes a second connecting plate 51, two symmetrically arranged second limiting posts 52, a second stud 53, and a clamping plate 54.

[0036] The second connecting plate 51 is respectively disposed on the first connecting block 3 and the second connecting block 4. The clamping plate 54 is movably connected to the second connecting plate 51 through the second stud 53. Two symmetrically arranged second limiting posts 52 are disposed on the clamping plate 54 and penetrate through the second connecting plate 51.

[0037] It should be noted that the two second connecting plates 51 proposed in the above embodiment are respectively installed on the first connecting plate 631 and the second connecting plate 51. Under the limiting action of the two symmetrically arranged second limiting posts 52, the second stud 53 is rotated in the forward direction to realize the extension of the clamping plate 54, clamping both sides of the plate grinding surface, while keeping the clamping surfaces on both sides with the first connecting block 3 and the second connecting block 4 respectively, so as to realize the thorough grinding of the grinding component 63.

[0038] In summary, the edge grinding device for coated plywood according to this utility model embodiment, by utilizing the first connecting block, the second connecting block and the assumed moving grinding mechanism between them, achieves reliable positioning and clamping of the board, flexible size adaptation and stability of the grinding process, and effectively improves the consistency of the board processing quality.
