Description

Technical Field

[0001] This utility model relates to the field of furniture board processing technology, and in particular to a multifunctional automatic surface-applying device for furniture boards. Background Technology

[0002] In the processing of furniture panels, surface lamination is an essential step to improve appearance and durability. Traditional lamination equipment has several shortcomings: the clamping structure is relatively simple, usually fixing the panel only on one side or at both ends, making it prone to misalignment during processing, especially with irregularly shaped or thin panels; manual flipping of the panels is required, which not only interrupts production and is inefficient but may also scratch the surface or pose operational risks; the clamping mechanism is not adjustable, has poor adaptability to panels of different lengths, and requires frequent component replacements, affecting production continuity; and unloading after lamination relies on manual operation, with a lack of coordination between hot pressing and conveying, resulting in an inconsistent overall rhythm. These factors increase production costs and time. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the use of a single clamping structure in existing equipment that can only fix the board on one side or both ends, which can easily lead to misalignment of the veneer due to board displacement during flipping or hot pressing, especially with insufficient stability control for irregularly shaped or thin boards; manual flipping requires interrupting the production process, which is not only inefficient but also poses a risk of scratching the board surface or injuring the operator; the fixed clamping mechanism of traditional equipment cannot accommodate boards of different lengths, requiring frequent adjustments or changes of tooling, which seriously affects the continuity of production; and the need for manual material removal after veneer is completed, with the lack of a coordination mechanism between the hot press and the conveying device, resulting in an inconsistent overall production cycle. Therefore, this invention proposes a multi-functional automatic veneer device for furniture boards.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multifunctional automatic surface-laminating device for furniture panels includes a workbench and a processing board.

[0006] A hot press is fixedly installed in the middle of the workbench, and a first rectangular hole and a second rectangular hole are respectively opened on both sides of the top of the workbench.

[0007] Multiple rotating rollers are rotatably connected inside the first rectangular hole for conveying the processed sheet material;

[0008] The inner walls on both sides of the second rectangular hole are provided with pre-fixing components for pre-fixing the processed sheet material;

[0009] The other two sides of the second rectangular hole are provided with horizontal holes, and a sliding horizontal plate slides through the horizontal holes. One end of the sliding horizontal plate is connected to a flipping component to realize the automatic flipping of the processed material.

[0010] An ejector assembly is provided below the workbench for ejecting the processed sheet material.

[0011] In one possible design, the pre-fixing component includes a side strip groove formed in the sidewall of the second rectangular hole, a side strip plate slidably disposed in the side strip groove, and the inner side of the side strip plate is an arc-shaped contact surface;

[0012] A compression spring is installed between the side strip plate and the end face of the side strip groove, and the compression spring is always in a compressed state.

[0013] In one possible design, the flipping assembly includes a rotating shaft that is rotatably connected to a circular groove at the end of the sliding crossbar.

[0014] One end of the rotating shaft is fixedly connected to the clamping plate, and the other end is circumferentially fixedly connected to the arc-shaped block;

[0015] A semi-circular groove is provided at the top of the circular groove, and the arc-shaped block is confined within the semi-circular groove.

[0016] In one possible design, the sliding cross plate has grooves on both sides, and a sliding plate is fixed to the inner wall of the cross hole, with the sliding plate and the groove forming a sliding fit.

[0017] The other end of the sliding plate is fixedly connected to a side limiting plate, and a tension spring connects the side limiting plate to the side wall of the worktable.

[0018] In one possible design, the ejection assembly includes a base plate, with a trapezoidal block and a top block fixed to the top of the base plate, the trapezoidal block having an inclination angle of 45°.

[0019] The top of the trapezoidal block is fixedly connected to the side vertical plate, and the side vertical plate is slidably connected to the side wall of the workbench;

[0020] The workbench is fixed with a side fixing plate, and an electric push rod is installed on the side fixing plate. The piston rod of the electric push rod is connected to the base plate.

[0021] In one possible design, an extension plate is fixed to the top of the side vertical plate, and a plug is fixed to the bottom of the extension plate;

[0022] Multiple slots are provided on the top surface of the sliding cross plate along the axial direction, and the insert rod and the slot form a clearance fit.

[0023] In one possible design, the top surface of the top block is provided with a rubber buffer layer, located directly below the second rectangular hole.

[0024] In this application, when in use, the processing plate is placed inside the second rectangular hole. Since the bottom and bottom of the two side strip plates are both arc-shaped, the side strip plates can be pressed against the two sides of the processing plate by the elastic force of the compression spring to pre-fix the processing plate. At this time, the stability of the processing plate can be temporarily maintained.

[0025] When the electric push rod is activated, the piston rod of the electric push rod moves the base plate downward, and the base plate moves the trapezoidal block downward. The trapezoidal block no longer resists the side limiting plate. At this time, the side limiting plate moves laterally under the tension of the tension spring. The side limiting plate moves the sliding horizontal plate laterally, and the sliding horizontal plate moves the rotating shaft and the clamping plate laterally. The clamping plate clamps the other two ends of the processed material. The tension of the tension spring is much greater than the elastic force of the compression spring, which can ensure the stability of the processed material.

[0026] When the two sliding horizontal plates approach each other, they can accommodate processing plates of different lengths. As the trapezoidal block continues to move down, the trapezoidal block drives the side vertical plate to move down, the side vertical plate drives the extension plate to move down, the extension plate drives the insertion rod to move down, and the insertion rod is inserted into the corresponding slot, which can brake the sliding horizontal plate and prevent the processing plate from coming loose.

[0027] At this point, the face paper and hot melt adhesive can be applied to the front of the processing board. After application, rotate the processing board so that the processing board drives the clamping plate to rotate to the reverse side. The clamping plate drives the rotating shaft to rotate, and the rotating shaft drives the arc block to rotate. The arc block rotates inside the semi-arc groove, which can prevent the processing board from being over-flipped.

[0028] After the processed material is flipped over, the side strip plate clamps the processed material again and pastes the face paper on the back of the processed material. After completion, the electric push rod is activated again. The electric push rod drives the trapezoidal block to move upward, thereby moving the side limit plate and the sliding cross plate out. At the same time, the bottom plate drives the top block to move upward, and the top block pushes out the processed material. Then, the processed material is hot-pressed and formed by the hot press. Multiple rotating rollers can help transport the processed material.

[0029] Beneficial effects: The pre-fixed component achieves initial centering and positioning of the board through the elastic cooperation of the arc-shaped side strip plate and the compression spring, avoiding initial placement offset;

[0030] The flipping assembly uses a tension spring to drive the sliding plate to clamp laterally. Its clamping force is much greater than the pre-fixed spring force, forming a two-stage fixation of "pre-positioning → strong clamping", which completely solves the problem of easy loosening of traditional single-point fixation.

[0031] The sliding crossbar achieves free lateral adjustment through a slide plate-slide groove structure. Combined with the extension plate insert rod and multi-slot locking design, it can adapt to various lengths of boards, breaking through the size limitations of traditional equipment.

[0032] The clamping plate, through a rotation limiting structure of a rotating shaft and a semi-circular groove, allows the plate to rotate axially adaptively when flipped 180°, avoiding adhesive peeling or plate deformation caused by rigid flipping.

[0033] The ejector assembly integrates an electric push rod drive system, which simultaneously achieves the dual actions of "side limit plate reset → top block ejection" through the trapezoidal block inclined surface. After the veneer is completed, the sheet material is automatically lifted to the conveyor roller table, eliminating the manual material handling process.

[0034] The flipping operation does not require interruption of the conveying process. The three processes of paper pasting, hot pressing and forming, and board conveying are synchronized through PLC control, which improves the overall production efficiency.

[0035] The horizontal hole-embedded sliding plate design allows the clamping mechanism to be completely housed inside the worktable, reducing the width of the equipment compared to traditional models.

[0036] The vertical linkage structure of the side vertical plate and the extension plate realizes the integration of three functions of "clamping → braking → ejection" in a limited space, reducing the equipment's footprint and making it more suitable for modern flexible production line layouts.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0043] In one embodiment; reference Figure 1-4 A laminating device includes: a main body consisting of a workbench 1, a hot press 4 fixedly mounted in the middle of the workbench 1, and a first rectangular hole 2 and a second rectangular hole 16 respectively opened on both sides of the top of the workbench 1. Multiple rotating rollers 3 are arranged equidistantly along the axial direction in the first rectangular hole 2, and the two ends of the rotating rollers 3 are connected to the side wall of the first rectangular hole 2 through bearings to form a board conveying channel.

[0044] Side strip grooves 19 are formed on both longitudinal side walls of the second rectangular hole 16. A side strip plate 18 is disposed in each side strip groove 19. Flanges on both sides of the side strip plate 18 form a sliding fit with the guide grooves on both sides of the side strip groove 19. An arc-shaped contact surface is provided on the inner side of the side strip plate 18. Two sets of compression springs 17 are installed between its outer end and the end face of the side strip groove 19. The compression springs 17 are always in a compressed state, so that the side strip plate 18 maintains a tendency to move towards the center of the second rectangular hole 16.

[0045] The second rectangular hole 16 has transverse holes 15 on its two side walls, with a sliding horizontal plate 29 passing through each hole 15. A circular groove 28 is formed at the end of the sliding horizontal plate 29, and a rotating shaft 26 is embedded within it. An arc-shaped block 23 is fixedly connected to the outer wall of the rotating shaft 26. A semi-circular groove 27 is formed at the top of the circular groove 28, and the arc-shaped block 23 forms a 180° rotation limit within the semi-circular groove 27. A clamping plate 24 is fixedly connected to the end of the rotating shaft 26. The clamping plate can be rectangular, curved, or serrated to enhance its adaptability to different material surfaces. Anti-slip textures are provided on the inner side of the clamping plate 24. A side limiting plate 13 is fixed to the other end of the sliding horizontal plate 29. A tension spring 22 is connected between the side limiting plate 13 and the side wall of the worktable 1. The preload of the tension spring 22 is set to 3-5 times the force of the compression spring 17. Slide grooves 21 are provided on both sides of the sliding plate 29, which form a sliding guide with the slide plate 25 fixed in the horizontal hole 15 to ensure the stability of lateral movement.

[0046] This application can be used in the field of furniture board processing, or in other fields applicable to this application.

[0047] In another embodiment; reference Figure 1-4A multifunctional automatic surface-applying device for furniture panels is disclosed. This device is used in the furniture panel processing field. A base plate 8 is installed below a workbench 1. Trapezoidal blocks 9 are fixed to both sides of the top of the base plate 8, with the slope angle of the trapezoidal blocks 9 set at 45°. A side vertical plate 6 is connected to the top of the trapezoidal blocks 9, and the side vertical plate 6 slides with a guide post on the side wall of the workbench 1 via a linear bearing. A top block 11 is fixed in the middle of the base plate 8, and a rubber buffer layer is provided on the upper surface of the top block 11. A side fixing plate 10 is fixed to the side wall of the workbench 1, and an electric push rod 5 is installed on the side fixing plate 10. The piston rod of the electric push rod 5 passes through the side fixing plate 10 and connects to the base plate 8. An extension plate 12 is connected to the top of the side vertical plate 6, and a plug rod 14 is fixed to the bottom of the extension plate 12. Equidistant slots 20 are opened on the top surface of a sliding horizontal plate 29 along the axial direction. The diameter of the plug rod 14 maintains a clearance fit of 0.1-0.2 mm with the inner diameter of the slot 20.

[0048] In actual operation, the operator places the processed board 7 flat in the area of ​​the second rectangular hole 16. The edge of the board triggers the side strip plate 18 to retract into the side strip groove 19, and the compression spring 17 generates a pre-tightening force to achieve initial positioning. The electric push rod 5 is activated to drive the base plate 8 downward, the trapezoidal block 9 disengages from the side limiting plate 13, the tension spring 22 pulls the side limiting plate 13 to move the sliding horizontal plate 29 towards the center, and the clamping plate 24 contacts the end face of the board to form the main clamping force. When the sliding horizontal plate 29 moves to the preset position, the extension plate 12 continues to descend with the side vertical plate 6, and the insertion rod 14 inserts into the corresponding slot 20 to achieve mechanical locking. At this time, the front-side bonding operation can be performed. After the front-side operation is completed, the board is manually flipped to drive the clamping plate 24 to rotate. The arc block 23 of the rotating shaft 26 rotates synchronously in the semi-arc groove 27, limiting the flipping angle to no more than 180°. After flipping, the side strip plate 18 is pre-fixed again to complete the reverse bonding. Finally, the electric push rod 5 moves upward, the trapezoidal block 9 pushes the side limit plate 13 to reset, and the top block 11 lifts the plate to the plane of the rotating roller 3, and then conveys it to the hot press 4 station for hot pressing.

[0049] This device achieves stable control throughout the processing through a dual-stage clamping system. The adaptive adjustment of the sliding cross plate 29, combined with the locking mechanism of the insertion rod 14, allows for the processing of sheet metal of various lengths. The flipping process does not require interruption of the conveying system, and the coordinated control of the ejection mechanism and the hot press 4 improves the overall production cycle efficiency.

[0050] However, as is well known to those skilled in the art, the working principle and wiring method of the electric actuator 5 are commonplace and are all conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
