Description

Technical Field

[0001] This invention belongs to the technical field of decorative panel molding, specifically relating to a double-sided molding device for ultra-matte wear-resistant PET decorative panels. Background Technology

[0002] PET, short for polyethylene terephthalate, is a high-performance material that combines excellent optical properties, superior film-forming properties, and durable weather resistance. PET raw materials are made into ultra-matte, wear-resistant films, which are then pressed onto both sides of decorative panels. This not only greatly enhances the color vibrancy and three-dimensional texture of the decorative panels but also makes them more durable.

[0003] In existing processes, PET film typically requires heat treatment to soften and make it viscous before being tightly bonded to the surface of a decorative panel using rollers. However, traditional molding equipment faces numerous challenges during operation: the installation of the PET film roll is cumbersome and inconvenient, and it is difficult to accurately align it with the decorative panel. This not only leads to a significant reduction in work efficiency but also easily causes uneven molding, seriously affecting the final quality of the product. Summary of the Invention

[0015] The advantages of this invention compared to the prior art are:

[0016] (1) In this invention, the PET film raw material roll is put into the barrel shaft, and then the telescopic shaft of the barrel shaft is contracted, so that the three supports rotate in the opposite direction. The two support rods of the three supports hold the barrel shaft, which facilitates the installation of the PET film raw material roll, so that the PET film raw material roll is facing the decorative panel, thereby making the mold flat.

[0017] (2) The present invention drives the double-headed lead screw to rotate by a positioning motor, thereby driving the two positioning plates to slide along the light rod to the middle at the same time, so that the positioning shaft contacts the two sides of the decorative plate at the same time, thereby ensuring that the decorative plate is in the middle of the roller shaft.

[0018] (3) When the decorative panel of the present invention passes through the two cleaning shafts of the dust collection component, the two cleaning shafts sweep off the dust on the upper and lower surfaces of the decorative panel respectively, and the dust collection fan sucks up the swept dust to prepare for the molding of the decorative panel.

[0019] (4) When the decorative panel of the present invention passes through two hot press rollers, the heating rod heats up to provide heat, and the heat is transferred through the hot press rollers to soften the PET film. The two hot press rollers move the decorative panel forward synchronously, and the hot press rollers press the two PET films on the upper and lower sides of the decorative panel. The two auxiliary pressure rollers of the second and third sets of sliding pressure components work together to further press the PET films on both sides of the decorative panel to ensure that the molding is firm.

[0020] (5) The present invention uses a feeding shaft to slowly lower the decorative panel into the finished product shelf, avoiding damage to the decorative panel after molding. At the same time, the feeding motor is started to drive the feeding screw to rotate, thereby moving the finished product shelf towards the power head. Then the power head is inserted into the inclined slide, thereby driving the power cylinder to rotate. The two finished side plates rotate to a horizontal state, thus making it easy to remove the molded decorative panel. Attached Figure Description

[0038] Example: Reference Figures 1-15 A double-sided molding device for ultra-matte wear-resistant PET decorative panels includes a frame 1. Multiple rollers 2 for transporting decorative panels 3 are rotatably mounted above the frame 1. A conveying motor 4 is mounted on the frame 1 below the first roller 2. A transmission mechanism 5 is provided between the rotating shaft of the conveying motor 4 and the roller 2. A transmission mechanism 5 is provided between adjacent rollers 2. A molding assembly is mounted on the frame 1 beside the last roller 2. The molding assembly includes a vertical mounting plate 601 and a material cylinder. The machine includes a shaft 602, three supports 604, and a support cylinder 605. A vertical mounting plate 601 is vertically mounted on the frame 1. Both the upper and lower ends of the vertical mounting plate 601 are rotatably equipped with a material cylinder shaft 602 for placing the PET film 603 raw material roll. The center of the three supports 604 is rotatably mounted on the frame 1. Two support rods of the three supports 604 are used to support the material cylinder shaft 602. One end of the support cylinder 605 is hinged to the third support rod of the three supports 604. The bottom of the cylinder body of the support cylinder 605 is hinged to the frame 1.

[0039] The transmission mechanism 5 consists of a transmission belt and two transmission wheels. The transmission belt is wound around the two transmission wheels, which are respectively installed on two shafts that need to transmit power. When one shaft rotates, the power is transmitted through the transmission mechanism 5 to drive the other shaft to rotate.

[0040] Specifically, the decorative panel 3 is placed on the roller 2, the conveying motor 4 is started, and the power is transmitted through the transmission mechanism 5. All the rollers 2 rotate synchronously, so the rollers 2 drive the decorative panel 3 to move. When the telescopic shaft of the bracket cylinder 605 extends, it drives the three brackets 604 to rotate, so that the two support rods of the three brackets 604 separate from the two material cylinder shafts 602. The PET film 603 raw material roll is put into the material cylinder shaft 602, and then the telescopic shaft of the material cylinder shaft 602 is contracted, so that the three brackets 604 rotate in the opposite direction, and the two support rods of the three brackets 604 hold the material cylinder shaft 602 again.

[0041] The molding assembly also includes three sets of sliding components. The sliding components include two vertical slide seats 606 mounted on the frame 1. A vertical slider 607 is slidably mounted in the vertical slide seat 606, and a bolt 608 is rotatably mounted on the upper part of the vertical slide seat 606. The bolt 608 and the vertical slider 607 form a threaded engagement. By rotating the bolt 608, the position of the vertical slider 607 in the vertical slide seat 606 can be adjusted according to the thickness of the PET film 603.

[0042] On the first set of sliding components, heating rods 609 are provided between the two vertical sliding seats 606 and between the two vertical sliding blocks 607. One end of each heating rod 609 passes through the vertical sliding seat 606 and the vertical sliding block 607 respectively and is fixedly installed on the heating rod frame 610. The heating rod frame 610 is fixedly installed on the vertical sliding seat 606. Hot pressure rollers 611 for rolling PET film 603 are rotatably sleeved on the outside of each heating rod 609. One end of each hot pressure roller 611 passes through the vertical sliding seat 606 and the vertical sliding block 607 respectively and is provided with interlocking large... Gear 612; Specifically, two PET films 603 are placed on two hot press rollers 611 respectively. Heating rod 609 provides heat, which is transferred through the hot press rollers 611 to soften the PET films 603. When the decorative panel 3 passes through the two hot press rollers 611, the lower hot press roller 611 rotates, and the power is transmitted through the two large gears 612 to make the upper hot press roller 611 rotate synchronously. The two hot press rollers 611 synchronously carry the decorative panel 3 forward, and the hot press rollers 611 press the two PET films 603 on the upper and lower surfaces of the decorative panel 3.

[0043] On the second and third sets of sliding components, auxiliary pressure rollers 613 for rolling PET film 603 are rotatably provided between the two vertical slide blocks 606 and between the two vertical sliders 607. One end of each of the two auxiliary pressure rollers 613 passes through the vertical slide block 606 and the vertical slider 607 respectively and is provided with a large gear 612 that meshes with each other. When the lower auxiliary pressure roller 613 rotates, the power is transmitted through the two large gears 612, causing the upper auxiliary pressure roller 613 to rotate. The two auxiliary pressure rollers 613 work together to further compact the PET film 603 on both sides of the decorative panel 3, and the two auxiliary pressure rollers 613 also move the decorative panel 3 forward.

[0044] The molding assembly also includes auxiliary shafts 614, 615, and 616 rotatably mounted on the frame 1. Transmission mechanisms 5 are provided between the last roller shaft 2 and the auxiliary pressure roller 613 below the second molding assembly, between auxiliary shaft 614 and auxiliary shaft 615, between auxiliary shaft 615 and auxiliary shaft 616, and between auxiliary shaft 616 and the auxiliary pressure roller 613 below the third molding assembly. A small gear 617 meshes between the large gear 612 below the first and second sliding components, and the small gear 617 is rotatably mounted on the vertical slide seat 606 of the second sliding component. Specifically, power is transmitted through all transmission mechanisms 5 to cause the auxiliary pressure rollers 613 below the second and third molding assemblies to rotate synchronously, and then power is transmitted through the small gear 617 and the large gear 612 to cause the hot pressure roller 611 below the first sliding component to rotate synchronously.

[0045] A damping disc 618 is provided at the end of the barrel shaft 602. A damping band 619 is wound around the outside of the damping disc 618. Both ends of the damping band 619 are provided with screws 620. Both screws 620 are inserted into the support plate 621, which is fixed to the side of the vertical mounting plate 601. Springs 622 are sleeved on the outside of the two screws 620. The two ends of the springs 622 are connected to the damping band 619 and the support plate 621, respectively. Springs 622 are provided on both screws 620. Specifically, the position of the adjusting nut 623 on the screw 620 is adjusted to adjust the tightness between the damping band 619 and the damping disc 618, thereby adjusting the damping force of the barrel shaft 602 rotation. This allows the PET film 603 to be taut. The springs 622 provide tension to keep the damping band 619 in contact with the damping disc 618.

[0046] Considering that the length of roller 2 is longer than the width of decorative panel 3, decorative panel 3 needs to be placed in the middle of roller 2 to align decorative panel 3 with PET film 603. Therefore, a positioning assembly is provided on frame 1 between roller 2. The positioning assembly includes two straight rods 701 fixed on frame 1, a double-ended lead screw 704 rotatably mounted on frame 1, and a positioning motor 705 fixed on frame 1. Two positioning shift plates 702 are slidably mounted on the straight rods 701. A positioning shaft 703 for positioning decorative panel 3 is rotatably mounted on the upper part of the positioning shift plate 702. The two positioning shift plates 702 are respectively threaded with the two ends of the double-ended lead screw 704. The double-ended lead screw 704 is connected to the rotating shaft of positioning motor 705.

[0047] Specifically, the positioning motor 705 drives the double-headed lead screw 704 to rotate, thereby driving the two positioning plates 702 to slide simultaneously along the guide rod 701 toward the middle, so that the positioning shaft 703 contacts the two sides of the decorative plate 3 at the same time, thereby ensuring that the decorative plate 3 is in the middle of the roller shaft 2.

[0048] Considering that the dust on both sides of the decorative panel 3 needs to be removed before molding, a dust collection assembly is provided on the frame 1 between the last two rollers 2. The dust collection assembly includes two vertical dust collection plates 801 mounted on the frame 1. Two cleaning shafts 802 for removing dust from the decorative panel 3 are rotatably mounted on the dust collection plates 801. A transmission mechanism 5 is connected between the two cleaning shafts 802. A transmission mechanism 5 is provided between the lower cleaning shaft 802 and the last two rollers 2. Dust collection boxes 803 are provided above and below the cleaning shafts 802. The upper dust collection box 803 is fixedly mounted on the top of the dust collection plate 801, and the lower dust collection box 803 is mounted in the opposite direction on the frame 1. A dust collection fan 804 for dust collection is provided on the top of the dust collection box 803.

[0049] Specifically, the power is transmitted through the transmission mechanism 5, causing the two cleaning shafts 802 to rotate simultaneously. The linear speed of the rotation of the cleaning shafts 802 is not the same as the speed of the movement of the decorative panel 3. When the decorative panel 3 passes the two cleaning shafts 802, the two cleaning shafts 802 sweep off the dust on the upper and lower surfaces of the decorative panel 3 respectively, and the vacuum fan 804 sucks up the swept dust.

[0050] After the decorative panel 3 is molded, the PET film 603 needs to be cut. A cutting assembly is provided on the side of the second set of sliding components. The cutting assembly includes a cutting frame 901 fixedly mounted on the vertical slide seat 606 of the second set of sliding components. A slide rod 902 is fixedly mounted on the cutting frame 901. A cutting screw 903 is rotatably mounted on the cutting frame 901. The cutting screw 903 is connected to the rotating shaft of the cutting motor 904. The cutting motor 904 is fixed on the cutting frame 901. A sliding cutting block 905 is slidably mounted on the slide rod 902, and the sliding cutting block 905 and the cutting screw 903 form a threaded engagement. A cutter 906 for cutting the PET film 603 is provided at the lower end of the sliding cutting block 905. Specifically, the cutting motor 904 drives the cutting screw 903 to rotate, thereby causing the sliding cutting block 905 to rotate along the slide rod 902. The cutter 906 below the sliding cutting block 905 cuts the PET film 603.

[0051] A feeding assembly is provided on the side of the molding assembly. The feeding assembly includes a feeding rack 1001 located on the side of the frame 1. Two slides 1002 are vertically mounted on the feeding rack 1001. The two slides 1002 are slidably mounted on a sliding frame 1003. A feeding electric cylinder 1004 is provided below the sliding frame 1003. The telescopic shaft of the feeding electric cylinder 1004 is connected to the sliding frame 1003. The feeding electric cylinder 1004 is fixedly mounted on the feeding rack 1001. Two rotating rods 1005 are symmetrically rotatably mounted on the feeding rack 1001. The ends of the rotating rods 1005 are provided with swing plates 1006. The ends of the swing plates 1006 are slidably engaged with the sliding grooves of the sliding frame 1003. Multiple feeding shafts 1007 are evenly rotatably mounted on the rotating rods 1005.

[0052] Specifically, in the initial state, the feeding shaft 1007 is in a horizontal state, the decorative panel 3 is placed on the feeding shaft 1007, the telescopic shaft of the feeding electric cylinder 1004 retracts, driving the sliding frame 1003 to descend, the sliding frame 1003 drives the two swing plates 1006 to rotate, thereby driving the rotating rod 1005 to rotate, and the feeding shaft 1007 rotates slowly accordingly, so the decorative panel 3 descends slowly on the feeding shaft 1007.

[0053] A side slide 1008 is fixedly installed on the unloading rack 1001 and below the rotating rod 1005. A finished product shelf 1009 for placing decorative panel 3 is slidably installed on the side slide 1008. An unloading screw 1010 is rotatably installed on the side slide 1008. The unloading screw 1010 and the bottom of the finished product shelf 1009 form a threaded engagement. The unloading screw 1010 is connected to the rotating shaft of the unloading motor 1011, and the unloading motor 1011 is fixedly installed on the side slide 1008.

[0054] Finished side panels 1012 are rotatably provided on both sides of the finished shelf 1009. A tension spring 1013 is provided between the rotating shaft of the finished side panel 1012 and the finished shelf 1009. A power cylinder 1014 is provided at the end of the rotating shaft of the finished side panel 1012. An inclined slide groove 1015 is provided on the power cylinder 1014. A power head 1016 for driving the inclined slide groove 1015 is provided on the side slide frame 1008.

[0055] The upper part of the finished side panel 1012 is provided with an inclined guide plate 1017 to facilitate the insertion of the decorative panel 3.

[0056] Specifically, in the initial state, the finished product shelf 1009 is located below the unloading shaft 1007, and the tension spring 1013 provides tension to keep the finished product side panel 1012 vertical. The decorative panel 3, which slides down from the unloading shaft 1007, falls into the finished product shelf 1009 after passing through the inclined guide plate 1017. The unloading motor 1011 is started to drive the unloading screw 1010 to rotate, thereby moving the finished product shelf 1009 towards the power head 1016. Then, the power head 1016 is inserted into the inclined slide groove 1015, thereby driving the power cylinder 1014 to rotate. The two finished product side panels 1012 then rotate to a horizontal state, so that the molded decorative panel 3 can be easily removed.

[0057] Working principle: In the initial state, the telescopic shaft of the support cylinder 605 extends, driving the three supports 604 to rotate. The two support rods of the three supports 604 separate from the two material cylinder shafts 602, and the PET film 603 raw material roll is put into the material cylinder shaft 602. Then, the telescopic shaft of the material cylinder shaft 602 retracts, causing the three supports 604 to rotate in the opposite direction. The two support rods of the three supports 604 hold the material cylinder shaft 602 again, facilitating the installation of the PET film 603 raw material roll. The two PET films 603 are respectively placed on the two hot press rollers 611. According to the thickness of the PET film 603, the position of the vertical slider 607 in the vertical slide seat 606 is adjusted by rotating the bolt 608. The telescopic shaft of the feeding cylinder 1004 is in the extended state, and the feeding shaft 1007 is in the horizontal state. The finished product placement plate 1009 is located below the feeding shaft 1007, and the tension spring 1013 provides tension to keep the finished product side plate 1012 in a vertical state.

[0058] The decorative panel 3 is placed on the roller 2. The positioning motor 705 of the positioning assembly is started. The positioning motor 705 drives the double-headed lead screw 704 to rotate, thereby driving the two positioning plates 702 to slide simultaneously along the guide rod 701 towards the middle, so that the positioning shaft 703 contacts the two sides of the decorative panel 3 at the same time, thus ensuring that the decorative panel 3 is in the middle of the roller 2. The conveying motor 4 is started, and the power is transmitted through the transmission mechanism 5. All the rollers 2 rotate synchronously, so the rollers 2 drive the decorative panel 3 to move. When the decorative panel 3 passes the dust collection assembly, the power is transmitted through the transmission mechanism 5, causing the two cleaning shafts 802 to rotate simultaneously. The linear velocity of the cleaning shafts 802 is not the same as the speed of the decorative panel 3. When the decorative panel 3 passes the two cleaning shafts 802, the two cleaning shafts 802 sweep off the dust on the top and bottom surfaces of the decorative panel 3 respectively. The dust collection fan 804 sucks up the swept dust, preparing the decorative panel 3 for molding.

[0059] When the decorative panel 3 passes through the molding assembly, power is transmitted through all the transmission mechanisms 5, causing the auxiliary pressure rollers 613 below the second and third molding assemblies to rotate synchronously. Power is then transmitted through the small gear 617 and the large gear 612, causing the hot pressure rollers 611 below the first set of sliding components to rotate synchronously. When the decorative panel 3 passes through the two hot pressure rollers 611, the heating rod 609 provides heat, which is transmitted through the hot pressure rollers 611 to soften the PET film 603. The lower hot pressure roller 611 rotates, and power is transmitted through the two large gears 612. Power is applied to the upper hot press rollers 611, which rotate synchronously. The two hot press rollers 611 move the decorative panel 3 forward, pressing the two PET films 603 onto the upper and lower surfaces of the decorative panel 3. The auxiliary pressure rollers 613 below the second and third sets of sliding pressing components rotate, transmitting power through two large gears 612, causing the upper auxiliary pressure rollers 613 to rotate. The two auxiliary pressure rollers 613 together further compact the PET films 603 on both sides of the decorative panel 3, and also move the decorative panel 3 forward. After the decorative panel 3 is molded, the sliding cutting block 905 of the cutting assembly is activated. The cutting motor 904 drives the cutting screw 903 to rotate, causing the sliding cutting block 905 to rotate along the sliding rod 902. The cutter 906 below the sliding cutting block 905 cuts the PET film 603. The cut PET film 603 is then overlapped on the hot press rollers 611, preparing for the molding of another decorative panel 3.

[0060] After molding, the decorative panel 3 moves onto the unloading shaft 1007. The telescopic shaft of the unloading electric cylinder 1004 retracts, driving the sliding frame 1003 to descend. The sliding frame 1003 drives the two swing plates 1006 to rotate, thereby driving the rotating rod 1005 to rotate. The unloading shaft 1007 rotates slowly accordingly, so the decorative panel 3 slowly descends onto the finished product placement plate 1009 on the unloading shaft 1007. The unloading motor 1011 is started to drive the unloading screw 1010 to rotate, thereby moving the finished product placement plate 1009 towards the power head 1016. Then the power head 1016 is inserted into the inclined slide groove 1015, thereby driving the power cylinder 1014 to rotate. The two finished product side plates 1012 rotate to a horizontal state, thus making it easy to remove the molded decorative panel 3.

[0061] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
