Description

Technical Field

[0001] This invention belongs to the field of PET decorative board film pressing technology, specifically a PET decorative board film pressing device. Background Technology

[0002] After PET is melt-extruded and biaxially stretched into a film, a polyurethane acrylate coating is applied to the surface. Then, an excimer UV curing technology is used to form a micro-wrinkled structure on the film surface to create an ultra-matte and wear-resistant film. The PET film is then laminated to both sides of the decorative panel through a hot-pressing process, giving the decorative panel a uniform high-grade matte texture and delicate skin feel. This effectively balances stress and prevents warping, and is widely used in high-end custom furniture and commercial space wall panels, becoming a modern surface solution that combines aesthetics and practicality.

[0003] Patent CN120056440A discloses a double-sided molding device for ultra-matte, wear-resistant PET decorative panels. The device includes a frame and multiple transport rollers connected in series via a transmission mechanism, driven by a transport motor. A molding assembly is located at the end of the frame, with a rotatable cylinder shaft at both ends of its vertical mounting plate for holding PET film rolls. Three supports are also rotatably mounted on the frame; two supports hold the cylinder shaft, and the third support is hinged to a support cylinder. In use, after the PET film roll is loaded into the cylinder shaft, the telescopic shaft retracts, causing the three supports to rotate in the opposite direction. The two supports lift the cylinder shaft, enabling convenient installation and precise positioning of the raw material roll, ensuring the PET film is aligned with the decorative panel, thus achieving flat double-sided molding.

[0004] In the above solution, after PET film is applied to both sides of the decorative panel, the lead screw needs to be driven to move the cutter to cut the PET film. Since the cutting component is fixed, the decorative panel needs to stop moving during the PET film cutting process, thereby pausing the film application to other decorative panels. Film cutting will waste a lot of time and reduce the efficiency of film application to decorative panels. Therefore, the present invention provides a PET decorative panel film pressing device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The PET decorative board film pressing device of the present invention includes a frame, a first conveying mechanism is provided on the frame, two sets of dust suction mechanisms are symmetrically arranged in front of the first conveying mechanism, a film pressing mechanism is provided in front of the dust suction mechanism, three sets of guide rollers are rotatably installed at equal distances in front of the film pressing mechanism, an edge trimming mechanism is provided in front of the guide rollers, a second conveying mechanism is provided in front of the edge trimming mechanism, the edge trimming mechanism includes two sets of first translation mechanisms, the two sets of first translation mechanisms are respectively arranged on both sides of the frame, support seats are fixedly installed on the first translation mechanisms, the two sets of support seats are used to support the second translation mechanism, an L-shaped rod is fixedly installed on the second translation mechanism, a knife holder is fixedly installed below the L-shaped rod, two sets of cutting blades are symmetrically arranged on both sides of the knife holder, and a photoelectric sensor is fixedly installed on a set of support seats; The edge trimming mechanism enables two sets of cutting blades to move synchronously with the moving PET decorative panel. During the synchronous movement, the two sets of cutting blades move laterally to cut the PET film, enabling the PET film to be cut without stopping the machine, thus improving the film application efficiency of the decorative panel.

[0007] Preferably, the cutter holder includes a base, an L-shaped rod fixedly connected to the upper end of the base, a rotating shaft rotatably installed in the base, two sets of cutting blades respectively installed at both ends of the rotating shaft, a gear set on the rotating shaft, a gear plate meshing with the gear, the gear plate movably inserted into the base, two sets of guide posts symmetrically inserted on both sides of the gear plate, springs sleeved on the guide posts, two sets of guide posts rotatably connected to both ends of the rollers respectively, two sets of grooves for engaging the rollers are opened at the bottom of the base, two sets of guide holes are symmetrically opened on the gear plate, the guide holes are slidably connected to the slide rods, the slide rods are fixedly installed in the base, two sets of baffles blocking the ends of the gear plates are symmetrically installed on the second translation mechanism, another set of support seats is also provided with photoelectric sensors, and rollers are rotatably installed at both ends of the gear plate; The first translation mechanism directly drives the two sets of support seats, together with the second translation mechanism, L-shaped rod, knife holder, and two sets of cutting blades to move in the opposite direction along the decorative panel, so that the photoelectric sensor returns to its initial position. There is no need to make the cutting blade move back along the cutting path, which saves the photoelectric sensor reset time and improves the efficiency of applying film to the decorative panel.

[0008] Preferably, a support mechanism is provided below the trimming mechanism. The support mechanism includes two sets of connecting frames. One end of each set of connecting frames is connected to two sets of support seats, and the other end of each set of connecting frames is connected to two sets of telescopic components. Each telescopic component includes two sets of movable seats. The movable seats are slidably installed in the frame, and the fixed seats are fixedly installed in the frame. Support rollers are rotatably installed on both the fixed seats and the movable seats. One set of nodes on the cross-cut telescopic frame is connected to the bottom of the fixed seat, and the other two sets on the cross-cut telescopic frame are connected to the bottom of the two sets of movable seats. Slide rails are fixedly installed on both sides of the frame. Slide grooves are opened at both ends of the movable seats, and the slide grooves are slidably connected to the slide rails. A pressure roller for pressing the PET decorative board is rotatably installed on the second conveying mechanism. The roller drives the movable seats along the slide rails to play a guiding role. The other end of the connecting frame is connected to the movable seats on the two sets of telescopic components. Two sets of movable seats drive the corresponding cross-scissor telescopic frames to extend and retract. The extension and retraction of the cross-scissor telescopic frames cause the movable seats to slide along the slide rails, and the distance between the two sets of movable seats increases or decreases. This allows the two sets of telescopic components to maintain support for the two sets of PET decorative panels during movement, preventing the PET decorative panels from deforming and thus ensuring the accuracy of cutting.

[0009] The beneficial effects of this invention are as follows: 1. The edge trimming mechanism enables two sets of cutting blades to move synchronously with the moving PET decorative panel. During the synchronous movement, the two sets of cutting blades move laterally to cut the PET film, enabling the PET film to be cut without stopping the machine, thus improving the film application efficiency of the decorative panel.

[0010] 2. When the PET decorative panel moves above the support mechanism, it drives multiple sets of support rollers on the support mechanism to rotate until the photoelectric sensor detects the end of the PET decorative panel. When the first translation mechanism drives the two sets of support seats together with the second translation mechanism, L-shaped rod, knife holder, and two sets of cutting blades to move with the decorative panel, during this process, the two sets of support seats drive the two sets of connecting frames to move. The connecting frames drive the movable seats on the two sets of telescopic components to move. The two sets of movable seats drive the corresponding cross-cut telescopic frames to extend and retract. The extension and retraction of the cross-cut telescopic frames will cause the movable seats to slide along the slide rail and increase or decrease the distance between the two sets of movable seats. This allows the two sets of telescopic components to maintain support for the two sets of PET decorative panels during movement, preventing deformation of the PET decorative panels and ensuring the accuracy of cutting.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figure 1 and Figure 2As shown in the figure, a PET decorative board film pressing device according to an embodiment of the present invention includes a frame 1, a first conveying mechanism 2 is provided on the frame 1, two sets of dust suction mechanisms 3 are symmetrically arranged vertically in front of the first conveying mechanism 2, a film pressing mechanism 4 is provided in front of the dust suction mechanism 3, three sets of guide rollers 5 are rotatably installed at equal distances in front of the film pressing mechanism 4, an edge trimming mechanism 7 is provided in front of the guide rollers 5, a second conveying mechanism 6 is provided in front of the edge trimming mechanism 7, the edge trimming mechanism 7 includes two sets of first translation mechanisms 701, the two sets of first translation mechanisms 701 are respectively provided on both sides of the frame 1, support seats 702 are fixedly installed on the first translation mechanisms 701, the two sets of support seats 702 are used to support the second translation mechanism 703, an L-shaped rod 704 is fixedly installed on the second translation mechanism 703, a knife holder 705 is fixedly installed below the L-shaped rod 704, two sets of cutting blades 706 are symmetrically arranged on both sides of the knife holder 705, and a photoelectric sensor 707 is fixedly installed on one set of support seats 702.

[0023] Specifically, both the first translation mechanism 701 and the second translation mechanism 703 adopt ball screw mechanisms in the prior art. The first conveying mechanism 2 and the second conveying mechanism 6 have the same structure. The first conveying mechanism 2, the dust collection mechanism 3, and the film pressing mechanism 4 adopt the conveying mechanism, dust collection component, and molding component in the above-mentioned double-sided molding device for ultra-dull wear-resistant PET decorative panels. When it is necessary to apply film to the decorative panel, the decorative panel is placed on the first conveying mechanism 2 at intervals. The first conveying mechanism 2 moves the decorative panel towards the film pressing mechanism 4. During the movement, the decorative panel passes through two sets of dust collection mechanisms 3. The two sets of dust collection mechanisms 3 remove the film from the decorative panel. After cleaning the dust and wood chips from both sides of the decorative panel, it enters the film pressing mechanism 4. The film pressing mechanism 4 heats, attaches, and presses the PET film onto the decorative panel. After film application, the decorative panel continues to move towards the edge trimming mechanism 7. At this time, the light emitted by the photoelectric sensor 707 is blocked by the edge of the decorative panel. As the decorative panel moves, the adjacent empty areas at the ends of the two sets of decorative panels will be illuminated by the light from the photoelectric sensor 707. At this time, the light from the photoelectric sensor 707 is no longer blocked and feeds a signal back to the controller of the device. The controller causes the two sets of first translation mechanisms 701 to drive the two sets of support seats 70 2. Together with the second translation mechanism 703, L-shaped rod 704, blade holder 705, and two sets of cutting blades 706, the two sets of cutting blades 706 move along with the decorative panel. At this time, the blades of the two sets of cutting blades 706 are facing the end edges of the two sets of decorative panels. The second translation mechanism 703 is activated, which drives the L-shaped rod 704, blade holder 705, and two sets of cutting blades 706 to move laterally. The two sets of cutting blades 706 will move along the end edges of the two sets of decorative panels to cut the PET film until the PET film covering the adjacent empty areas at the ends of the two sets of decorative panels is cut off. Then, the cutting blades 706 are retracted along the previous cutting path. Then, the first translation mechanism 706 is activated. Mechanism 701 drives two sets of support seats 702, together with the second translation mechanism 703, L-shaped rod 704, knife holder 705, and two sets of cutting blades 706, to move in the opposite direction to the moving decorative panel, so that the photoelectric sensor 707 returns to the initial position and waits for the arrival of the next set of PET decorative panels. The above operation is repeated cyclically. Compared with the prior art, the two sets of cutting blades 706 move synchronously with the moving PET decorative panel through the trimming mechanism 7. During the synchronous movement, the two sets of cutting blades 706 move laterally to cut the PET film, realizing the cutting of PET film without stopping the device, thus improving the film application efficiency of the decorative panel.

[0024] like Figures 3 to 5As shown, the cutter holder 705 includes a base 7051, with an L-shaped rod 704 fixedly connected to the upper end of the base 7051, a rotating shaft 7052 rotatably mounted inside the base 7051, two sets of cutting blades 706 respectively mounted at both ends of the rotating shaft 7052, a gear 7053 mounted on the rotating shaft 7052, a gear plate 7054 meshing with the gear 7053, the gear plate 7054 movably inserted into the base 7051, two sets of guide posts 7055 symmetrically inserted on both sides of the gear plate 7054, springs 7056 sleeved on the guide posts 7055, and rollers 7057. Two sets of guide posts 7055 are rotatably connected to the ends respectively. Two sets of grooves 7058 for engaging rollers 7057 are opened at the bottom of the seat body 7051. Two sets of guide holes 7059 are symmetrically opened on the toothed plate 7054. The guide holes 7059 are slidably connected to the slide rod 7060. The slide rod 7060 is fixedly installed in the seat body 7051. Two sets of baffles 708 blocking the ends of the toothed plate 7054 are symmetrically installed on the second translation mechanism 703. Another set of support seats 702 is also provided with photoelectric sensors 707. Rollers 7061 are rotatably installed at both ends of the toothed plate 7054.

[0025] Specifically, after the cutting blade 706 cuts off the PET film covering the adjacent empty areas at the ends of the two sets of decorative panels, it first needs to return laterally along the cutting path, and then move to the initial position of the photoelectric sensor 707 in the opposite direction of the movement of the PET decorative panel. The lateral and reverse movement not only makes the reset path of the photoelectric sensor 707 more complicated, but also wastes a lot of time and reduces the efficiency of applying film to the decorative panel. In the initial state, the roller 7057 engages with a set of grooves 7058. After the cutting blade 706 cuts the PET film along the edge of the decorative panel, the cutting blade 706 faces away from the decorative panel. The second translation mechanism 703 continues to drive the L-shaped rod 704, the blade holder 705, and the two sets of cutting blades 706 to move laterally. During the movement, a set of rollers 7061 on the blade holder 705 is blocked by the corresponding baffle 708 and cannot move. At the same time, the baffle 708 pushes the toothed plate 7054 to move through the rollers 7061. The toothed plate 7054 drives the gear 7053 to rotate. The rotating gear 7053 drives the two sets of cutting blades 706 to rotate through the rotating shaft 7052. At the same time, the toothed plate 7054 drives the two sets of guide posts 7055 to move together with the rollers 7057, causing the rollers 7057 to disengage from the current position. The roller 7057 is squeezed by the groove 7058, causing the roller 7057 to drive the two sets of guide posts 7055 to move upward and compress the two sets of springs 7056 until the roller 7057 engages with the other set of grooves 7058 under the rebound force of the springs 7056. At this time, the blade of the inclined cutting knife 706 is facing the decorative panel. Therefore, the first translation mechanism 701 drives the two sets of support seats 702 together with the second translation mechanism 703, L-shaped rod 704, knife holder 705, and two sets of cutting knives 706 to move in the opposite direction along the decorative panel so that the photoelectric sensor 707 returns to the initial position. There is no need to make the cutting knife 706 move back along the cutting path, saving the reset time of the photoelectric sensor 707 and thus improving the efficiency of applying film to the decorative panel.

[0026] Example 2: Figures 6 to 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: A support mechanism 9 is provided below the trimming mechanism 7. The support mechanism 9 includes two sets of connecting frames 901. One end of each set of connecting frames 901 is connected to two sets of support seats 702, and the other end of each set of connecting frames 901 is connected to two sets of telescopic components 902. The telescopic components 902 include two sets of movable seats 9021. The movable seats 9021 are slidably installed in the frame 1, and the fixed seats 9022 are fixedly installed in the frame 1. Support rollers 9023 are rolledly installed on both the fixed seats 9022 and the movable seats 9021. The cross-cutting extension... A set of nodes on the telescopic frame 9024 is connected to the bottom of the fixed seat 9022. The other two sets on the scissor-type telescopic frame 9024 are respectively connected to the bottom of the two sets of movable seats 9021. Slide rails 903 are fixedly installed on both sides inside the frame 1. Slide grooves 211 are opened at both ends of the movable seat 9021. The slide grooves 211 are slidably connected to the slide rails 903. A pressure roller 8 for pressing the PET decorative board is rotatably installed on the second conveying mechanism 6. It drives the movable seat 9021 along the slide rail 903 to play a guiding role. The other end of the connecting frame 901 is connected to the movable seats 9021 on the two sets of telescopic components 902.

[0027] Specifically, during the cutting of the PET film, the moving PET decorative panel is suspended without support. Since the PET decorative panel is quite long, the unsupported part of the PET decorative panel will bend slightly under the influence of gravity, thus affecting the accuracy of the cutting. Initially, one set of telescopic components 902 is in a retracted state, and the other set is in an extended state. When the PET decorative panel moves above the support mechanism 9, the PET decorative panel will drive the multiple sets of support rollers 9023 on the support mechanism 9 to rotate until the photoelectric sensor 707 detects the end of the PET decorative panel. When the first translation mechanism 701 drives the two sets of support seats 702 together with the second translation mechanism 703, L-shaped rod 704, knife holder 705, and two sets of cutting blades 706 to move with the decorative panel, during this process, the two sets of support seats 702... 2. The two sets of connecting frames 901 move, and the connecting frames 901 move the movable seats 9021 on the two sets of telescopic components 902. The two sets of movable seats 9021 drive the corresponding cross-type telescopic frames 9024 to extend and retract. The extension and retraction of the cross-type telescopic frames 9024 will cause the movable seats 9021 to slide along the slide rail 903, and make the distance between the two sets of movable seats 9021 larger or smaller, so that the two sets of telescopic components 902 can maintain support for the two sets of PET decorative boards during movement, avoid deformation of the PET decorative boards, and thus ensure the accuracy of cutting.

[0028] Working principle: Decorative panels are placed at intervals on the first conveying mechanism 2. The first conveying mechanism 2 moves the decorative panels towards the film pressing mechanism 4. During the movement, the decorative panels pass through two sets of dust suction mechanisms 3, which clean the dust and wood chips on both sides of the decorative panels. Then, the decorative panels enter the film pressing mechanism 4, where the film pressing mechanism 4 heats, attaches, and presses the PET film onto the decorative panels. After film application, the decorative panels continue to move towards the edge trimming mechanism 7. At this time, the light emitted by the photoelectric sensor 707 is blocked by the edge of the decorative panel. As the decorative panels move, the adjacent empty areas at the ends of the two sets of decorative panels will be illuminated by the light from the photoelectric sensor 707. At this time, the light from the photoelectric sensor 707 is no longer blocked, and the signal is fed back to the controller of the device. The controller causes the two sets of first translation mechanisms 701 to drive the two sets of support seats 702 together with the second translation mechanism 701. 03. The L-shaped rod 704, the blade holder 705, and the two sets of cutting blades 706 move together with the decorative panel. At this time, the blades of the two sets of cutting blades 706 are facing the edge of the two sets of decorative panels. The second translation mechanism 703 is activated. The second translation mechanism 703 drives the L-shaped rod 704, the blade holder 705, and the two sets of cutting blades 706 to move laterally. The two sets of cutting blades 706 will move along the edge of the two sets of decorative panels to cut the PET film until the PET film covering the adjacent empty area at the end of the two sets of decorative panels is cut off. Then, the cutting blades 706 are withdrawn along the previous cutting route. Then, the first translation mechanism 701 drives the two sets of support seats 702 together with the second translation mechanism 703, the L-shaped rod 704, the blade holder 705, and the two sets of cutting blades 706 to move in the opposite direction of the movement of the decorative panel, so that the photoelectric sensor 707 returns to the initial position and waits for the arrival of the next set of PET decorative panels. The above operation is repeated in a loop. After the cutting blade 706 cuts the PET film along the edge of the decorative panel, the blade of the cutting blade 706 faces away from the decorative panel. The second translation mechanism 703 continues to drive the L-shaped rod 704, the blade holder 705, and the two sets of cutting blades 706 to move laterally. During this movement, a set of rollers 7061 on the blade holder 705 is blocked by the corresponding baffle 708 and cannot move. Simultaneously, the baffle 708 pushes the toothed plate 7054 to move via the rollers 7061. The toothed plate 7054 drives the gear 7053 to rotate. The rotating gear 7053 drives the two sets of cutting blades 706 to rotate via the rotating shaft 7052. At the same time, the toothed plate 7054 drives the two sets of guide pillars 7055 along with the rollers 7057 to move. The movement causes the roller 7057 to disengage from the current groove 7058, and the roller 7057 is squeezed by the groove 7058, causing the roller 7057 to drive the two sets of guide pillars 7055 to move upward and compress the two sets of springs 7056 until the roller 7057 engages with another set of grooves 7058 under the rebound force of the springs 7056. At this time, the blade of the inclined cutting knife 706 is facing the decorative panel. Therefore, the first translation mechanism 701 directly drives the two sets of support seats 702, together with the second translation mechanism 703, L-shaped rod 704, knife holder 705, and the two sets of cutting knives 706 to move in the opposite direction along the decorative panel, so that the photoelectric sensor 707 can return to the initial position. When the PET decorative panel moves above the support mechanism 9, it drives the multiple sets of support rollers 9023 on the support mechanism 9 to rotate until the photoelectric sensor 707 detects the end of the PET decorative panel. When the first translation mechanism 701 drives the two sets of support seats 702 together with the second translation mechanism 703, L-shaped rod 704, knife holder 705, and two sets of cutting blades 706 to move with the decorative panel, during this process, the two sets of support seats 702 drive the two sets of connecting frames 901 to move. The connecting frames 901 drive the movable seats 9021 on the two sets of telescopic components 902 to move. The two sets of movable seats 9021 drive the corresponding cross-shaped telescopic frames 9024 to extend and retract. The extension and retraction of the cross-shaped telescopic frames 9024 will cause the movable seats 9021 to slide along the slide rail 903 and make the distance between the two sets of movable seats 9021 larger or smaller, so that the two sets of telescopic components 902 can maintain support for the two sets of PET decorative panels during movement.
