Description

Technical Field

[0001] This invention belongs to the field of composite board processing technology, and specifically relates to a composite board processing equipment. Background Technology

[0002] In the field of decorative materials, composite panels are widely used for cladding and edge sealing of interior wall panels. These composite panels consist of a solid base layer and a surface layer adhered to the base layer. The base layer is a solid board of a certain thickness, such as solid wood, medium-density fiberboard, particleboard, or plastic board, providing structural support. The surface layer is a thin decorative material such as decorative paper, PVC film, thin wood veneer, or metal foil, adhered to the surface of the base layer with adhesive, serving both decorative and protective functions. In practical applications, to improve the product's aesthetics and edge sealing, the surface layer needs to be bent and wrapped around the edges of the base layer, ensuring a close fit.

[0003] To achieve the aforementioned edge-wrapping effect, the bottom layer edge needs to be pre-treated before bending. Part of the bottom layer is removed, leaving the top layer suspended at the bottom layer edge, so that the top layer can be bent and adhered later.

[0004] Currently, the aforementioned folding process is typically completed in steps by multiple independent machines. For example, the material is first crushed and scraped on one machine, and then transferred to the folding machine for bending. The material transfer between each process not only increases labor costs and operating time, but also easily leads to cumulative errors due to multiple clamping and positioning, ultimately resulting in quality problems such as uneven folds and poor adhesion between the surface and the bottom layers. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a composite board processing equipment, which aims to solve the problem that the folding process in the prior art is usually completed step by step by multiple independent machines, resulting in uneven folding and poor adhesion between the surface layer and the bottom layer.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 9 This invention provides a composite board processing device, wherein the composite board 103 includes a bottom layer 1031 and a top layer 1032 bonded together, the bottom layer 1031 being located below the top layer 1032, and includes:

[0039] Rack 101;

[0040] A conveyor belt 102 is mounted on the frame 101 and is used to convey the composite plate 103 along the X direction. The composite plate 103 is laid flat on the conveyor belt 102.

[0041] The first grooving mechanism 201 is disposed on the frame 101 and located upstream of the conveyor belt 102. The first grooving mechanism 201 is used to open an isolation groove 104 at the bottom of the bottom layer 1031. The length direction of the isolation groove 104 extends along the X direction, the thickness direction of the isolation groove 104 extends along the Z direction, and the bottom of the isolation groove 104 does not contact the surface layer 1032.

[0042] A crushing mechanism 301 is disposed on the frame 101 and located downstream of the first grooving mechanism 201. The crushing mechanism 301 is used to crush the bottom material 1031 between the edge of the isolation groove 104 and the bottom material 1031 to form a clearance groove 105.

[0043] The second grooving mechanism 401 is disposed on the frame 101 and located downstream of the crushing mechanism 301. It is used to open a receiving groove 106 on the edge of the bottom layer 1031. The length direction of the receiving groove 106 extends along the X direction, the depth direction of the receiving groove 106 extends along the Y direction, the Y direction is perpendicular to the X direction and is located in the horizontal plane, and the Z direction is perpendicular to the horizontal plane where the X direction and the Y direction are located.

[0044] The cleaning mechanism 501 is disposed on the frame 101 and located downstream of the second grooving mechanism 401. The cleaning mechanism 501 is used to scrape off the bottom layer 1031 material between the clearance groove 105 and the surface layer 1032 to expose the surface layer 1032.

[0045] The scoring mechanism 601 is disposed on the frame 101 and located downstream of the cleaning mechanism 501, and is used to score fold lines 107 on the bottom surface of the surface layer 1032 after the bottom layer 1031 has been scraped off.

[0046] The first folding mechanism 701 is disposed on the frame 101 and located downstream of the scoring mechanism 601. It is used to bend the top surface of the top layer 1032 after the bottom layer 1031 has been scraped off along the fold line 107 and attach it to the edge of the bottom layer 1031.

[0047] The second folding mechanism 801 is disposed on the frame 101 and located downstream of the first folding mechanism 701, and is used to fold the surface layer 1032 into the receiving groove 106.

[0048] Specifically, the composite board 103, driven by the conveyor belt 102, passes through each processing station sequentially, completing all edge folding processes. In the first grooving process, the isolation groove 104 partially separates the edge portion of the bottom layer 1031 from the main body portion in the thickness direction, providing a guiding boundary for subsequent processing. In the crushing process, the bottom layer 1031 material outside the isolation groove 104 is removed by crushing, creating space for subsequent cleaning and folding processes. In the second grooving process, the receiving groove 106 is used to accommodate the folded surface layer 1032 in the subsequent folding process. In the cleaning process, the remaining bottom layer 1031 material below the clearance groove 105 is completely removed by cleaning, exposing the bottom surface of the surface layer 1032, preparing for subsequent folding. In the scoring process, the folding line 107 serves as a guide line for subsequent bending, making the bending position precise and controllable, and preventing the surface layer 1032 from shifting during bending. In the first folding process, the surface layer 1032 is bent from a horizontal state to a vertical state. In the second folding process, the edge of the surface layer 1032 is further bent from a vertical state to a horizontal state and embedded in the receiving groove 106, completing the folding process.

[0049] According to some feasible embodiments, a glue spraying mechanism 108 is provided between the scoring mechanism 601 and the first folding mechanism 701. The glue spraying mechanism 108 is used to spray adhesive onto the exposed bottom surface of the surface layer 1032 and / or the edge of the bottom layer 1031. Specifically, before the first folding mechanism 701 bends the surface layer 1032 and attaches it to the edge of the bottom layer 1031, the glue spraying mechanism 108 evenly sprays adhesive onto the exposed bottom surface of the surface layer 1032 or the edge of the bottom layer 1031. When the first folding mechanism 701 completes the bending action, the surface layer 1032 is attached to the edge of the bottom layer 1031 under pressure, and the adhesive then cures, forming a strong adhesive layer, ensuring that the folded part will not easily separate during subsequent processing and use.

[0050] According to some feasible embodiments, the first grooving mechanism 201 includes a first grooving motor 202 and a first saw blade 203. The first saw blade 203 is disposed at the power output end of the first grooving motor 202, and the rotation axis of the first saw blade 203 extends along the Y direction. When the first grooving motor 202 drives the first saw blade 203 to rotate, the first saw blade 203 rotates and cuts in the XZ plane. As the composite board 103 is conveyed along the X direction, the first saw blade 203 cuts into the bottom of the bottom layer 1031 along the Z direction, forming a continuous isolation groove 104 extending along the X direction.

[0051] According to some feasible embodiments, the crushing mechanism 301 includes a crushing motor 302 and a crushing saw blade 303. The crushing saw blade 303 is located at the power output end of the crushing motor 302, and the rotation axis of the crushing saw blade 303 extends along the Y direction. The thickness of the first saw blade 203 is less than the thickness of the crushing saw blade 303. In this embodiment, since the thickness of the crushing saw blade 303 is greater than that of the first saw blade 203, it can remove a wider layer of bottom material 1031 in one pass, thoroughly crushing and removing the bottom material 1031 on the outside of the isolation groove 104 to form an avoidance groove 105, providing sufficient operating space for subsequent cleaning and scraping processes. Because the first saw blade 203 is thinner, it is used for precision cutting of the isolation groove 104, with a narrow and high-precision cut, maintaining a smooth cutting surface and providing an accurate reference for subsequent processing. The crushing saw blade 303 is thicker, used for efficiently removing the bottom material 1031 on the outside of the isolation groove 104, effectively improving material removal efficiency.

[0052] According to some feasible embodiments, the second grooving mechanism 401 includes a second grooving motor 402 and a second saw blade 403. The second saw blade 403 is disposed at the power output end of the second grooving motor 402, and the rotation axis of the second saw blade 403 extends along the Z direction. When the second grooving motor 402 drives the second saw blade 403 to rotate, the second saw blade 403 rotates and cuts in the XY plane. As the composite board 103 is conveyed along the X direction, the second saw blade 403 cuts into the edge of the bottom layer 1031 along the Y direction, forming a continuous receiving groove 106 extending along the X direction.

[0053] According to some feasible embodiments, the cleaning mechanism 501 includes a cleaning motor 502 and a cleaning milling cutter 503. The cleaning milling cutter 503 is located at the power output end of the cleaning motor 502, and the rotation axis of the cleaning milling cutter 503 extends along the Y direction. When the cleaning motor 502 drives the cleaning milling cutter 503 to rotate, the cutting edge of the cleaning milling cutter 503 mills away the remaining bottom layer 1031 material between the clearance groove 105 and the surface layer 1032, precisely controlling the milling depth to ensure that the surface layer 1032 is just exposed without damaging it.

[0054] According to some feasible embodiments, the scoring mechanism 601 includes a scoring motor 602 and a scoring saw blade 603. The scoring saw blade 603 is located at the power output end of the scoring motor 602, and the rotation axis of the scoring saw blade 603 extends along the Y direction. When the scoring motor 602 drives the scoring saw blade 603 to rotate, the scoring saw blade 603 scores fold lines 107 on the bottom surface of the surface layer 1032 after the bottom layer 1031 has been scraped off. The depth of the fold lines 107 needs to be precisely controlled to ensure that the surface layer 1032 bends precisely along the fold lines 107 during bending, while avoiding excessive scoring that could cause the surface layer 1032 to break.

[0055] According to some feasible embodiments, the first folding mechanism 701 includes a plurality of rollers 702 rotatably connected to the frame 101. The rollers 702 are arranged sequentially along the conveying direction of the composite board 103. Each roller 702 is used to abut against and bend the top surface of the surface layer 1032 after the bottom layer 1031 has been scraped off. The rotation axis of each roller 702 forms an angle with the conveying plane of the composite board 103. The angles of the rollers 702 are different and increase progressively along the conveying direction of the composite board 103, so that the top surface of the surface layer 1032 after the bottom layer 1031 has been scraped off is gradually bent to a predetermined final angle after passing through the rollers 702. In this embodiment, the rotation axis of the rollers 702 forms an angle with the conveying plane of the composite board 103, and the angles of the rollers 702 are different and increase progressively along the conveying direction of the composite board 103. That is, the tilt angle of the first roller 702 is relatively small (e.g., 30°), and the tilt angle of the subsequent rollers 702 gradually increases (e.g., 45°, 60°, 90°).

[0056] As the composite board 103 moves along the conveying direction, the surface layer 1032, after the bottom layer 1031 has been scraped off, passes sequentially through each roller 702. Each roller 702 bends the surface layer 1032 at a certain angle, and multiple rollers 702 gradually bend the surface layer 1032 from a horizontal state to a vertical state. This progressive bending avoids cracking or stress concentration in the surface layer 1032 caused by a large-angle bend in one go.

[0057] Furthermore, several of the rollers 702 are respectively connected to buffer cylinders 804. The buffer cylinders 804 are mounted on the frame 101, and their power output ends are connected to the corresponding rollers 702. The buffer cylinders 804 provide elastic cushioning when the rollers 702 bend the surface layer 1032 to absorb the impact force during the bending process. When the rollers 702 abut against the top surface of the surface layer 1032 after the bottom layer 1031 has been scraped off and bend it, the thickness of the surface layer 1032 may have slight fluctuations, or the material hardness of the surface layer 1032 may be uneven, causing the rollers 702 to be subjected to uneven reaction forces. The buffer cylinders 804 absorb the impact force and pressure fluctuations generated during the bending process through the elastic deformation of the compressed gas inside, maintaining flexible contact between the rollers 702 and the surface layer 1032, and avoiding indentations or damage to the surface layer 1032 caused by rigid collisions. Meanwhile, the buffer cylinder 804 can automatically adapt to the thickness changes of the surface layer 1032, so that each roller 702 always maintains stable contact with the surface layer 1032, ensuring the consistency of bending angle and the uniformity of bending quality.

[0058] According to some feasible embodiments, the first folding mechanism 701 includes a hot air gun 703 mounted on the frame 101, which blows hot air onto the surface layer 1032 after the bottom layer 1031 has been scraped off. Before bending, the hot air gun 703 blows hot air onto the bending area of ​​the surface layer 1032 to heat and soften the material of the surface layer 1032. The softened surface layer 1032 has increased toughness, reducing the bending force required during bending, making the bending process smoother, and effectively avoiding bending breakage due to material brittleness. At the same time, the hot air can also activate the adhesive sprayed by the adhesive spraying mechanism 108, enhancing the bonding strength between the surface layer 1032 and the edge of the bottom layer 1031.

[0059] According to some feasible embodiments, the second folding mechanism 801 includes a plurality of pointed wheels rotatably connected to the frame 101. These pointed wheels are arranged sequentially along the conveying direction of the composite plate 103, with their rotation axes extending along the Z-direction. The flanges of the pointed wheels face the receiving groove 106, and the pointed wheels are used to insert the top layer 1032, after the bottom layer 1031 has been scraped off, into the receiving groove 106. Further, the plurality of pointed wheels includes a first pointed wheel 802 and a second pointed wheel 803 arranged sequentially along the conveying direction of the composite plate 103. The tip of the first pointed wheel 802 is provided with an arc-shaped guide surface facing the opening of the receiving groove 106, for abutting against the end of the top layer 1032 after the bottom layer 1031 has been scraped off, and guiding the end of the top layer 1032 into the receiving groove 106 as the top layer 1032 moves with the composite plate 103.

[0060] The tip of the second pointed wheel 803 is provided with a planar pressing surface, which is located downstream of the arc-shaped guide surface and is used to abut against the upper surface of the surface layer 1032 that has entered the receiving groove 106, and press the surface layer 1032 tightly against the upper surface of the receiving groove 106.

[0061] Because the tip of the first pointed wheel 802 has an arc-shaped guide surface, which faces the opening of the receiving groove 106, when the top layer 1032, after the bottom layer 1031 has been scraped off, moves along the X direction with the composite plate 103 to the first pointed wheel 802, the arc-shaped guide surface of the first pointed wheel 802 abuts against the end of the top layer 1032. Because the arc-shaped guide surface has a smooth curved profile, it applies a gradually increasing guiding force to the end of the top layer 1032 through rolling contact, guiding the end of the top layer 1032 smoothly into the receiving groove 106. Under the action of the arc-shaped guide surface, the end of the top layer 1032 is initially folded into the receiving groove 106, but at this time the top layer 1032 is not yet completely attached to the upper surface of the receiving groove 106; a certain angle is still maintained between the top layer 1032 and the upper surface of the receiving groove 106 (i.e., the top layer 1032 is in an inclined state and not completely flattened).

[0062] The tip of the second pointed wheel 803 is provided with a planar pressing surface, which is located downstream of the arc-shaped guide surface. When the end of the surface layer 1032 has entered the receiving groove 106 and continues to move forward with the composite plate 103 to the second pointed wheel 803, the planar pressing surface of the second pointed wheel 803 abuts against the upper surface of the surface layer 1032. The planar pressing surface is parallel to the upper surface of the receiving groove 106. By applying upward pressure to the surface layer 1032, it completely embeds the surface layer 1032 into the receiving groove 106 and presses it tightly against the upper surface of the receiving groove 106, so that a tight surface contact is formed between the surface layer 1032 and the upper surface of the receiving groove 106.

[0063] Similarly, both the first pointed wheel 802 and the second pointed wheel 803 are connected to a buffer cylinder 804.

[0064] Furthermore, an inner wheel 901 is provided downstream of the second folding mechanism 801. The inner wheel 901 is rotatably connected to the frame 101 and is used to shape the crease formed by the first folding mechanism 701. During the folding process of the composite board 103, the first folding mechanism 701 bends the surface layer 1032 along the fold line 107 to a vertical state, forming a crease. This crease is located at the bending part of the surface layer 1032 and is the key deformation area where the surface layer 1032 changes from a horizontal to a vertical state. It is also the outermost corner of the entire folding structure. Since this crease is directly exposed to the outermost part of the product, its appearance quality directly affects the aesthetics of the final product and customer acceptance. Therefore, it is necessary to precisely shape the crease.

[0065] After the composite plate 103 completes the second fold (inserting the surface layer 1032 into the receiving groove 106) via the second folding mechanism 801, it continues to move forward to the inner wheel 901. The wheel surface of the inner wheel 901 rolls into contact with the crease formed by the first folding mechanism 701, applying uniform pressure to the crease. The inner wheel 901 does not change the fold shape formed by the second folding mechanism 801, but only shapes the crease formed by the first folding mechanism 701. The first folding mechanism 701 bends the surface layer 1032 90° along the fold line 107, forming an outwardly convex crease corner. This crease is the outermost corner of the entire folding structure, and its cross-sectional profile is convex outward. The peripheral side of the inner wheel 901 is concave inward, and the cross-sectional profile of its groove is geometrically complementary to the convex shape of the crease. When the inner wheel 901 presses against the crease, the concave wheel surface can surround and wrap the convex part of the crease, so that the pressure is evenly distributed along the arc surface of the crease, rather than forming a line contact only at the highest point of the crease. Under the combined action of pressure and rolling, the material at the crease gradually flattens and adheres, eliminating the slight arches or wrinkles caused by springback and improving the flatness of the folded edge.

[0066] Similarly, the inner wheel 901 is connected to the buffer cylinder 804.

[0067] Furthermore, several conical wheels 902 are provided downstream of the inner circular wheel 901. In decorative material applications, two composite panels 103 are usually spliced ​​together using profiles to form a larger decorative surface. During splicing, the edges of the two composite panels 103 move closer to the profiles, and only the outermost edge of the surface layer 1032 that is in contact with the bottom layer 1031 (i.e., the outermost end of the folded edge of the surface layer 1032) is exposed at the seam. The thickness of this outermost edge of the surface layer 1032 is extremely thin (usually only 0.2mm to 2mm, depending on the thickness of the surface layer 1032 material), and the flatness and fit of this outermost edge directly determine the visual quality of the seam. If a regular cylindrical straight wheel (i.e., a pressing wheel with a flat cylindrical surface) is used to shape the fold, the entire width of the straight wheel will contact the surface layer 1032 that is in contact with the bottom layer 1031 and the unwrapped bottom layer 1031. Due to unavoidable dimensional errors and positional deviations during the processing of composite board 103 (such as straightness errors at the edges of the bottom layer 1031 and slight deviations in the bending angle of the surface layer 1032), the side surface of composite board 103 is not perfectly straight along its width. When the straight roller contacts the entire side surface of composite board 103, the pressure of the roller surface will preferentially act on the higher areas of the side surface, while the outermost edge may fail to contact the straight roller due to its lower position or the presence of slight depressions. This results in the outermost surface layer 1032 not being pressed tightly, and after splicing, gaps, warping, or poor adhesion may appear at the joint, affecting the product's aesthetics and sealing performance.

[0068] The conical wheel 902 in this application has a conical surface structure, wider at the top and narrower at the bottom, so that the outermost surface layer 1032 abuts against the conical wheel 902. When the conical wheel 902 rolls over the outermost surface layer 1032, the contact area is extremely small. Due to the small contact area, the pressure of the conical wheel 902 is concentrated on the outermost surface layer 1032, unaffected by dimensional errors or positional deviations in other areas. Even if there are minor protrusions or depressions in other areas, they will not affect the pressing effect of the conical wheel 902 on the outermost surface layer 1032.

[0069] Similarly, the conical wheel 902 is connected to the buffer cylinder 804.
