Description

Technical Field

[0001] This utility model relates to the field of sheet coating technology, and in particular to a contour coating device. Background Technology

[0002] Melamine board, also known as melamine-impregnated paper-faced engineered wood, is a decorative board made by soaking paper with different colors or textures in melamine resin adhesive, drying it to a certain degree of curing, and then laying it on the surface of particleboard, moisture-resistant board, medium-density fiberboard, plywood, blockboard, multi-layer board or other hard fiberboard, and then hot-pressing it.

[0003] Melamine boards are typically covered with a film. The conventional method involves first laying a film on the upper surface of the melamine board, then flipping it 180° to lay another film on the lower surface before sealing the edges. This method usually involves a flat-lay structure, as illustrated by a CNC large-panel hot glue wrapping machine disclosed in Chinese Patent Publication No. CN217993516U. This flat-lay method requires flipping and subsequent edge sealing, resulting in low efficiency. Furthermore, the film-coated boards formed by this edge sealing method have gaps at the corners, poor coverage, and are prone to water seepage.

[0041] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] Example 1

[0043] Please refer to Figures 1 to 7 This embodiment discloses a contouring coating device, including a contouring coating mechanism. The contouring coating mechanism includes a conveying device 41 for conveying a vertically placed sheet 61 along the x-direction, a plurality of first uprights 42 and second uprights 43 respectively disposed on both sides of the conveying device 41 along the y-direction, a first side wheel 44 disposed on the first uprights 42 and with adjustable height, a second side wheel 45 disposed on the second uprights 43 and with adjustable height, and a pressing wheel 46 located directly above the conveying device 41.

[0044] The positions of the first side wheel 44 and the second side wheel 45 along the y direction are adjustable;

[0045] At least a portion of the continuous first side wheels 44 can be adjusted to be arranged in a linear, downward-sloping configuration along the feeding direction;

[0046] At least a portion of the continuous second side wheels 45 can be adjusted to be arranged in a linear, downward-sloping configuration along the feeding direction;

[0047] The conveying device 41 includes a plurality of bottom wheels 412 spaced apart along the x-direction and a fourth drive device 430 for driving all bottom wheels 412 to rotate synchronously.

[0048] The contour-following coating device of this embodiment can be used to produce PVC coated panels with a height of 600cm or more. The structure of the PVC coated panel is not limited to right-angled panels, slanted right-angled panels, rounded corner panels, handle-free panels, or other irregular panel structures. During production, the first side wheel 44 and the second side wheel 45 of the contour-following coating mechanism guide the film material 62 to gradually cover both ends of the panel 61 along the y-direction via the linearly arranged first side wheel 44 and second side wheel 45. This application uses a contour-following coating mechanism to perform coating production on vertically conveyed panels 61, enabling simultaneous coating of both ends of the panel 61 along the y-direction, improving efficiency. Moreover, by using a wrapping method, the upper end of the panel 61 does not need to be sealed, and the wrapped structure has the characteristics of being integrally formed, seamless, with good water resistance and better aesthetics.

[0049] The contouring coating mechanism of this embodiment includes a conveying device 41, a first side wheel 44, a second side wheel 45, and a pressing wheel 46. The conveying device 41 includes a plurality of bottom wheels 412 spaced apart along the x-direction and a fourth driving device 430 for driving all bottom wheels 412 to rotate synchronously. This application uses spaced bottom wheels 412 as the bottom support and driving mechanism for the sheet material 61, resulting in better conveying stability for conveying heavier sheet materials 61. The first side wheels 44 and second side wheels 45 serve as rolling supports for the sheet material 61 on both sides along the y-direction, enabling the sheet material 61 to be conveyed linearly along the x-direction, preventing misalignment and ensuring subsequent coating accuracy. At least a portion of the continuous first side wheels 44 can be adjusted to a downward-sloping linear arrangement along the feeding direction, and at least a portion of the continuous second side wheels 45 can be adjusted to a downward-sloping linear arrangement along the feeding direction. After the film material 62 passes through the contouring rolling of the first side wheels 44 and the second side wheels 45, as... Figure 7 As shown, the membrane material 62 can be gradually applied to both ends of the plate 61 along the y-direction, achieving automatic application and demonstrating a clever structure. Furthermore, the positions of the first side wheel 44 and the second side wheel 45 along the y-direction are adjustable, allowing for adjustments based on different thicknesses of the plate 61, thus providing good compatibility. The pressing wheel 46 serves as a pressing mechanism for the top membrane material 62 of the plate 61, using rolling to ensure that the membrane material 62 covers the upper end of the plate 61.

[0050] Furthermore, the conveying device 41 in this embodiment also includes a fourth bearing 411 and a gear transmission device 413. One end of the bottom wheel 412 along the y-direction is rotatably connected to the fourth bearing 411, and the other end is drive-connected to the gear transmission device 413. The fourth drive device 430 is a worm gear drive device, and the fourth drive device 430 is drive-connected to the gear transmission device 413. In this embodiment, the bottom wheel 412 is used for conveying. Since the bottom wheels 412 can be set at intervals, other structures for bottom contouring film coating can be set between the two bottom wheels 412 in the future.

[0051] Furthermore, the contouring coating mechanism also includes a conveyor table 47, a first spacing adjustment mechanism 48, and a conveying device 41 located at the upper middle part of the conveyor table 47 along the x-direction.

The first drive device 486 drives the first frame 484 and the second frame 485 to move synchronously in opposite directions or in the same direction, thereby driving the first side wheel 44 and the second side wheel 45 to move synchronously in opposite directions or in the same direction, so that the center of symmetry of the first side wheel 44 and the second side wheel 45 along the y-direction is always consistent with the center of the conveying path of the conveying device 41, thereby adjusting the position of the plate 61 more accurately.

[0053] In a preferred embodiment, the first driving device 486 includes a first motor 4861, a first worm gear connected to the output end of the first motor 4861, a first worm meshing with the first worm gear, a first lead screw 4862 connected to the first worm gear and having a first threaded portion and a second threaded portion, a first lead screw sleeve 4863 meshing with the first threaded portion, and a second lead screw sleeve 4864 meshing with the second threaded portion; the first lead screw sleeve 4863 is fixedly connected to the first frame 484, and the second lead screw sleeve 4864 is fixedly connected to the second frame 485; the first upright 42 is fixed to the first frame 484, and the second upright 43 is fixed to the second frame 485. The worm gear and worm wheel enable synchronous relative or reverse adjustment of the left and right clamping, and the first lead screw with both positive and negative threads provides a self-locking function during adjustment, resulting in high adjustment accuracy.

[0054] Furthermore, the contouring coating mechanism of this embodiment also includes a frame 49, a lifting adjustment mechanism 410, and a second spacing adjustment mechanism 420; the lifting adjustment mechanism 410 includes a second drive device 4101 fixed on the frame 49 and driven to lift along the z-direction, and a top frame 4102 connected to the output end of the second drive device 4101.

[0056] This embodiment adds a third upright 4205 and a fourth upright 4208. The third upright 4205 and the first upright 42 form a set of lifting and adjusting rods, and the fourth upright 4208 and the second upright 43 form a set of lifting and adjusting rods. The height of the third upright 4205 and the fourth upright 4208 can be adjusted by the lifting and adjusting mechanism 410, which can adapt to the processing of various height plates 61. Moreover, it shortens the length of a single upright, which is equivalent to dividing a long upright in half, so that the stress on the upright is halved, making it less prone to deformation. In addition, the entire row can be adjusted in a coordinated manner, which is ingenious.

[0057] Furthermore, the second drive device 4101 includes a second motor fixed to the frame 49, a second lead screw sleeve driven by the second motor, a second lead screw threaded to the second lead screw sleeve and capable of rising and falling along the z-direction, a connecting plate fixed to the lower end of the second lead screw, and a top frame 4102 fixedly connected to the connecting plate; the adjustment is highly accurate through the lead screw, and the lead screw has a thread and a self-locking function, which makes the structure more stable after adjustment.

[0058] Furthermore, the third drive device 4210 includes a third motor, a third worm gear connected to the output end of the third motor, a third worm gear meshing with the third worm gear, a third lead screw connected to the third worm gear and having a third threaded portion and a fourth threaded portion, a third lead screw sleeve meshing with the third threaded portion, and a fourth lead screw sleeve meshing with the fourth threaded portion.

The pressing wheel 46 is raised and lowered by the third upright 4205 and the fourth upright 4208, thereby adjusting the pressing height of the pressing wheel 46.

[0060] The first side wheel 44 is mounted on the first upright 42 via a cross-connecting shaft 440; the second side wheel 45 is mounted on the second upright 43 via a cross-connecting shaft 440. Installation via the cross-connecting shaft 440 makes adjustment easy.

[0061] The frame 49 is provided with a slide rail 450 along the z-direction, and the top frame 4102 is provided with a sliding block 460 that slides with the slide rail 450. The sliding engagement between the sliding block 460 and the slide rail 450 improves the stability of the top frame 4102 moving along the z-direction.
