Description

Technical Field

[0001] This invention belongs to the field of planar composite machine technology, and particularly relates to a heating inlet mechanism with an adjustable inlet angle for a planar composite machine. Background Technology

[0002] In industries such as packaging printing, advertising production, and electronic material lamination, planar laminating machines are core processing equipment. The main function of their heating inlet mechanism is to preheat the composite substrate to bring its surface temperature up to the required level, while reducing the surface tension of the substrate and improving the activation efficiency of the laminating adhesive, thereby ensuring the bonding strength and flatness of the laminated product.

[0003] A search revealed Chinese Patent Publication No. CN106042588B, which discloses a heating roller structure for a flatbed composite machine. The structure includes a frame, an upper support frame, and a lower support frame. The upper support frame is mounted on the frame via an upper gap adjustment device, and the lower support frame is mounted on the frame via a lower gap adjustment device. The upper and lower gap adjustment devices have identical structures. The upper gap adjustment device comprises a dual-shaft output reduction motor fixedly mounted on the upper end of the frame. Gearboxes are respectively mounted on both sides of the frame at the lower end of the dual-shaft output reduction motor. The motor shafts at both ends of the dual-shaft output reduction motor are connected to the input ends of the gearboxes via universal joints. The output ends of the gearboxes are connected to the upper support frame via adjusting screws. An upper conveyor belt is mounted on the upper support frame via an upper pulley. Several upper pressure rollers are evenly arranged on the upper support frame on the inner side of the lower end of the upper conveyor belt.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Traditional heating inlet mechanisms are typically fixed, with the angle of the inlet guide plate and the gap between it and the material surface being fixed and unadjustable. When processing materials of different thicknesses, materials, or tension states, the fixed inlet angle and gap may cause the material to vibrate, scratch, or wrinkle at the inlet, or even generate static electricity or scratches due to friction, thereby causing damage to the material during the heating process. Furthermore, the fixed heating gap cannot be optimized for sealing according to the material thickness, resulting in a large amount of heat leakage from the gap. This not only wastes energy but also affects the temperature stability of the heating zone, thereby reducing the heating quality and efficiency of the heating inlet mechanism.

[0005] Therefore, the present invention provides a heating inlet mechanism with an adjustable inlet angle for a planar composite machine to solve the above-mentioned problems. Summary of the Invention

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] 1. In this invention, by setting up an angle adjustment mechanism and a gap adjustment mechanism, the travel of the rotating column is limited by an arc-shaped guide plate. Then, with the cooperation of an arc-shaped rack and a moving gear, the rotating column performs an arc-shaped movement, thereby causing the rotating column to drive the guide roller to move synchronously. The arc-shaped displacement of the guide roller realizes the change of angle between the guide roller and the upper and lower heating mechanisms. At the same time, with the cooperation of the lifting rack and the transmission gear, the position of the upper heating mechanism is changed, thereby adjusting the distance between the upper and lower heating mechanisms. The combined motion mechanism of angle change and gap change is realized through the cooperation of the two adjustment mechanisms, realizing precise and independent control of the inlet geometry. This allows the planar composite machine to heat materials of different thicknesses, materials, or tension states, ensuring that the materials do not shake, scratch, wrinkle, or even generate static electricity or scratches due to friction at the inlet, further ensuring the protection of the materials by the heating inlet mechanism.

[0031] 2. In this invention, a guide roller and a spiral wire are provided. The spiral wire is symmetrically distributed on the outer surface of the guide roller. When the guide roller rotates, the spiral wire will pull the two sides of the material towards the two ends of the guide roller, thereby pulling the material to be laid flat on the outer surface of the guide roller, thus ensuring the flatness of the material during feeding and ensuring the uniformity of the material heating.

[0032] 3. In this invention, by setting up a baffle mechanism, under the action of the bidirectional threaded rod, the threaded plate drives the baffles to move closer or further apart, thereby adjusting the distance between the baffles to meet the needs of materials of different widths. During the material heating process, by adhering to both sides of the material, the heat is sealed inside the material, effectively preventing heat leakage from the material and ensuring the stability of the material heating temperature. This not only improves the heating effect of the material but also improves the heating uniformity of the material.

[0033] 4. In this invention, a reciprocating mechanism and a heating rod are provided. The moving rod moves in cooperation with the cam and the roller. With the cooperation of the connecting spring, the moving rod moves back and forth. The reciprocating movement of the moving rod causes the heating rod to move back and forth synchronously. The reciprocating movement of the heating rod can effectively prevent the material from sticking to the heating rod during the heating process, which would cause damage to the material and further ensure the overall quality of the material during the heating process.

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In specific implementation, such as Figures 1-10 As shown, this utility model provides a technical solution: a heating inlet mechanism with an adjustable inlet angle for a planar composite machine, including a support frame 1, a support plate 5 fixedly and symmetrically fixedly installed on the upper surface of the support frame 1, a support column 2 fixedly and symmetrically fixedly installed on the inner wall of the ground of the support frame 1, a lower heating mechanism 3 and an upper heating mechanism 4 are provided inside the support frame 1, and a reciprocating mechanism 9 is provided inside both the lower heating mechanism 3 and the upper heating mechanism 4.

[0048] An angle adjustment mechanism 7 is disposed on the outer surface of the support frame 1. The angle adjustment mechanism 7 includes an arc-shaped guide plate 703, which is symmetrically fixedly installed on the two side walls of the support frame 1. The arc-shaped guide plate 703 has a through stroke groove inside, and a sliding groove 704 is provided on the side wall of the arc-shaped guide plate 703. An arc-shaped rack 705 is fixedly installed on the inner arc surface of the arc-shaped guide plate 703.

[0049] The angle adjustment mechanism 7 also includes a rotating column 701. A guide roller 702 is rotatably mounted on the outer surface of the rotating column 701. A spiral guide wire is symmetrically arranged on the outer surface of the guide roller 702. Both ends of the rotating column 701 pass through the stroke grooves of the symmetrical arc-shaped guide plate 703. A movable gear 708 is symmetrically fixedly mounted on the outer surface of the rotating column 701. The movable gear 708 meshes with the arc-shaped rack 705.

[0050] A stepper motor 7010 is fixedly installed at one end of the rotating column 701. A support base 709 is fixedly installed on the lower surface of the stepper motor 7010. One end of the support base 709 is slidably connected to the inner wall of the stroke groove. A limit plate 706 is rotatably installed at the other end of the rotating column 701. A limit pin 707 is fixedly installed on the side wall of the limit plate 706. One end of the limit pin 707 is slidably connected to the inner wall of the slide groove 704.

[0051] Specifically, by setting an angle adjustment mechanism, the stepper motor 7010 operates on the support base 709. At this time, the stepper motor 7010 drives the rotating column 701 to rotate between the two arc-shaped guide plates 703. As the rotating column 701 rotates, it drives the moving gear 708 on the surface to rotate synchronously. Under the guidance of the arc-shaped rack 705, the moving gear 708 drives the rotating column 701 to slide in an arc under the limit of the stroke groove and the slide groove 704, so that the rotating column 701 drives the guide roller 702 to move synchronously. By making the guide roller 702 perform arc-shaped movement, the angle between the guide roller 702 and the upper heating mechanism 4 and the lower heating mechanism 3 is changed. During the material conveying process, the guide roller 702 will rotate on the outer surface of the rotating column 701. At this time, the guide roller 702 will drive the spiral guide to rotate synchronously. Since the spiral direction of the spiral guide is opposite, the spiral guide will stretch the two sides of the material towards the two ends of the guide roller 702, thereby ensuring the flatness of the material during the conveying process.

[0052] A spacing adjustment mechanism 6 is disposed on the upper surface of the support plate 5. The spacing adjustment mechanism 6 includes a drive seat 602. The lower surface of the drive seat 602 is fixedly connected to the upper surface of the corresponding support plate 5. A drive rod 604 is fixedly installed between the drive seats 602. Fixed seats 605 are symmetrically fixedly installed on the upper surface of the support frame 1. The fixed seats 605 are distributed on both sides of the drive seats 602. A connecting rod 603 is fixedly installed between the fixed seats 605 and the drive seats 602.

[0053] A rotating rod 608 is rotatably mounted on the inner wall of the cavity of the drive base 602. Both ends of the rotating rod 608 extend to the outside of the drive base 602. A driving bevel gear 609 is fixedly mounted on the outer surface of the rotating rod 608. One end of the rotating rod 608 is fixedly connected to one end of the driving rod 604. A servo motor 601 is fixedly mounted on the upper surface of the support plate 5. The output end of the servo motor 601 is fixedly connected to the other end of the rotating rod 608. Positioning rods 6010 are rotatably mounted on the inner walls of the cavities on the other two sides of the drive base 602. One end of the positioning rod 6010 extends into the interior of the drive base 602 and is fixedly mounted with a driven bevel gear 6011. The driven bevel gear 6011 meshes with the driving bevel gear 609. The other end of the positioning rod 6010 extends to the outside of the drive base 602 and is fixedly connected to one end of the connecting rod 603.

[0054] A fixed cylinder 6012 is connected to the side wall of the fixed base 605. A movable rod 6013 is rotatably installed on the inner wall of the cavity of the fixed cylinder 6012. One end of the movable rod 6013 extends to the outside of the fixed cylinder 6012 and is fixedly connected to the other end of the connecting rod 603. A transmission gear 6014 is fixedly installed on the outer surface of the movable rod 6013. A lifting gear 606 is slidably installed inside the fixed base 605. The lifting gear 606 passes through the inside of the fixed base 605 and extends into the inside of the support frame 1. The lifting gear 606 and the transmission gear 6014 mesh with each other. A connecting seat 607 is fixedly installed on the lower surface of the lifting gear 606.

[0055] Specifically, by setting the spacing adjustment mechanism 6, the servo motor 601 drives the rotating rod 608 to rotate within the drive seat 602. The rotating rod 608 drives the driving bevel gear 609 to rotate within the drive seat 602. As the driving bevel gear 609 rotates, the driven bevel gear 6011 causes the positioning rod 6010 to rotate on the inner wall of the cavity of the drive seat 602. When the rotating rod 608 rotates, it also drives the driving rod 604 to rotate synchronously. Under the connection of the driving rod 604, the structure within another drive seat 602 rotates. When the positioning rod 6010 rotates... The connecting rod 603 drives the movable rod 6013 to rotate within the fixed cylinder 6012. At this time, the positioning rod 6010 drives the transmission gear 6014 to rotate synchronously within the fixed cylinder 6012. As the transmission gear 6014 rotates, the lifting gear 606 moves up and down within the fixed seat 605, thereby driving the upper heating mechanism 4 to move up and down synchronously via the connecting seat 607. This adjusts the distance between the upper heating mechanism 4 and the lower heating mechanism 3, ensuring that the distance between them matches the thickness of the material and guaranteeing the heating effect.

[0056] A baffle mechanism 8 is disposed on the outer surface of the lower heating mechanism 3. The baffle mechanism 8 includes a baffle 805, which is symmetrically disposed above the lower heating mechanism 3. A groove 806 is provided on the upper surface of the baffle 805. Several support springs 807 are fixedly installed at equal intervals on the inner wall of the bottom surface of the groove 806. A movable plate 808 is fixedly installed on one end of the support spring 807, and one end of the movable plate 808 extends to the top of the groove 806.

[0057] The partition mechanism 8 also includes a bidirectional threaded rod 801. An mounting sleeve 802 is rotatably mounted on the outer surface of the bidirectional threaded rod 801. A threaded plate 804 is threadedly mounted on the outer surface of the bidirectional threaded rod 801. The threaded plate 804 has a threaded hole inside that matches the thread on the surface of the bidirectional threaded rod 801. The upper surface of the threaded plate 804 is fixedly connected to the lower surface of the baffle 805. A drive motor 803 is fixedly mounted on the side wall of one of the mounting sleeves 802. The output end of the drive motor 803 is fixedly connected to one end of the bidirectional threaded rod 801.

[0058] Specifically, by setting up a baffle mechanism 8, the drive motor 803 drives the bidirectional threaded rod 801 to rotate under the limit of the mounting sleeve 802. As the bidirectional threaded rod 801 rotates, the threaded plate 804 will drive the baffle 805 to move closer or further apart above the lower heating mechanism 3 under the action of the thread. This adjusts the distance between the two baffles 805 so that the distance between the baffles 805 matches the width of the material. Thus, during the material heating and conveying process, the baffles 805 are always in contact with the edge of the material, thereby reducing heat leakage within the material. When the movable plate 808 is squeezed by the upper heating mechanism 4, it will shrink into the groove 806 of the baffle 805, thereby realizing the variability of the baffle 805 and meeting the sealing requirements for materials of different thicknesses.

[0059] The upper heating mechanism 4 includes a movable frame 401, the upper surface of which is fixedly connected to the lower surface of the connecting seat 607. A fixed column 402 is fixedly installed on the side wall of the movable frame 401. A slider 403 is fixedly installed at one end of the fixed column 402.

The outer surface of the pulley 3012 is slidably connected to the inner wall of the slide rail 307. The lower surface of the baffle 805 is in contact with the upper surface of the heating rods 309.

[0062] The reciprocating mechanism 9 includes a fixed plate 901 and a positioning seat 905. The fixed plate 901 is located between fixed rods 306. The end face of the fixed plate 901 is fixedly connected to the side wall of the fixed rod 306. A connecting spring 902 is fixedly installed on the side wall of the fixed plate 901. One end of the connecting spring 902 is fixedly connected to the outer surface of the moving plate 3011. A moving rod 903 is fixedly installed on the inner wall of the fixed plate 901. One end of the moving rod 903 passes through the interior of the connecting spring 902 and is fixedly connected to the outer surface of the moving plate 3011. The other end of the moving rod 903... The end is provided with an installation groove, and a roller 904 is rotatably installed on the inner wall of the installation groove via a rotating shaft. The side wall of the positioning seat 905 is fixedly connected to the side wall of the fixing frame 301. A control motor 906 is fixedly installed on the other side wall of the positioning seat 905. A rotating rod 907 is fixedly installed at the output end of the control motor 906. One end of the rotating rod 907 passes through several fixing rods 306. Cams 908 are fixedly installed at equal intervals on the outer surface of the rotating rod 907. The cams 908 are located between the fixing rods 306, and the outer surface of the cams 908 contacts the outer surface of the roller 904.

[0063] Specifically, by setting up a lower heating mechanism 3, an upper heating mechanism 4, and a reciprocating mechanism 9, the positioning plate 304 is moved by an electric push rod 303. At this time, the positioning plate 304 will move the conveying roller 305, thereby adjusting the position of the conveying roller 305 in the upper heating mechanism 4 and the lower heating mechanism 3 according to the angle of the guide roller 702. During the heating process of the material, the control motor 906 drives the rotating rod 907 to rotate between the fixed rods 306. At this time, the rotating rod 907 will drive the cam 908 to rotate synchronously. As the cam 908 rotates, the moving rod 903 is displaced under the limit of the fixed plate 901 under the action of the roller 904. At this time, the moving rod 903 will drive the moving plate 3011 to move synchronously. Under the action of the connecting spring 902, the moving plate 3011 slides back and forth between the slide rails 307 through the pulley 3012. At this time, the moving plate 3011 drives the support rod 308 to move synchronously through the connecting block 3010. The support rod 308 drives the heating rod 309 to move synchronously back and forth. During the heating process, the material is blocked by the baffle 805. Therefore, the material will not wrinkle when the heating rod 309 moves back and forth. At the same time, the reciprocating movement of the heating rod 309 can also avoid the material from sticking to the heating rod 309 due to long-term contact, thus affecting the heating quality of the material.

[0064] Working principle: The height of the upper heating mechanism 4 is adjusted by the spacing adjustment mechanism 6 to match the distance between the upper heating mechanism 4 and the lower heating mechanism 3 with the thickness of the composite material. Then, the distance between the baffles 805 in the partition mechanism 8 is adjusted to match the width of the composite material. The composite material is then conveyed between the upper heating mechanism 4 and the lower heating mechanism 3 under the guidance of the guide roller 702 in the angle adjustment mechanism 7. During the conveying process, the angle of the guide roller 702 can be adjusted by the angle adjustment mechanism 7 to change the material entry angle, allowing the material to enter the upper heating mechanism 4 and the lower heating mechanism 3 smoothly. The composite material is then heated by the cooperation of the upper heating mechanism 4 and the lower heating mechanism 3. During the heating process, the reciprocating mechanism 9 drives the lower heating mechanism 3 to reciprocate. At this time, the composite material is conveyed along a fixed path under the obstruction of the partition mechanism 8. The reciprocating motion of the lower heating mechanism 3 can effectively prevent the heating rod 309 in the lower heating mechanism 3 from sticking to the composite material, thus ensuring the heating effect of the composite material.
