Description

Technical Field

[0001] This invention relates to the field of wood-plastic composite board processing equipment technology, specifically to a molding wood-plastic composite board coating and packaging device. Background Technology

[0002] The pre-formed wood-plastic composite board (WPC) film-coating and packaging device is a key end-stage equipment in the production and processing of WPC. It is mainly used in the post-processing of pre-formed WPC in fields such as building decoration and furniture manufacturing. Its core function is to stack multiple pre-formed WPCs neatly and then achieve integrated film-coating and packaging through processes such as film covering, heat sealing, and heat shrinking. This not only protects the surface of the WPC from scratches and contamination during transportation and storage, but also improves the neatness and aesthetics of the product. Currently, existing technologies for laminating and packaging pre-formed wood-plastic composite (WPC) boards mainly fall into a combination of semi-automatic and manual methods: WPC boards are manually stacked one by one onto a conveyor table, then conveyed to a laminating equipment for protective film application, and finally conveyed to a heat shrink oven for heat shrinking treatment to achieve the laminating effect. However, manual stacking of WPC boards can easily lead to unevenness on the sidewalls and ends. Some equipment is equipped with simple edge-blocking structures to limit the stacked WPC boards on one side. However, in actual use, the following drawbacks also exist: Although some equipment is equipped with a single-sided limiting plate to limit the loading of wood-plastic composite boards, manually stacked wood-plastic composite boards are still prone to misalignment at the ends, which makes subsequent lamination difficult, and wrinkles and bubbles are easily generated after lamination. Poor alignment at the sealing point seriously affects the appearance of the product. Summary of the Invention

The two positioning plates 4443 slide away from each other along the guide plate 4442, so that both positioning plates 4443 abut against the inner side wall of the upper film roll, thus positioning the upper film roll. The lower film roll is placed outside the lower positioning rod 4441, and the same process is used to position the lower film roll. The electric heating wire inside the control heating wheel 431 is turned on, causing the temperature of the heating wheel 431 to rise. The upper film is pulled and wound around the top of the upper guide roller 442, and the lower film is wound around the bottom of the lower guide roller 441. The ends of the upper and lower films are then pulled through between the two heating wheels 431 located on both sides of the mounting frame 41. The two heating wheels 431 on both sides of the mounting frame 41 heat-melt the two sides of the upper and lower films, causing the two sides of the upper and lower films to bond together. The films are then pulled to the upper heating plate 427 and the lower heating plate near the guide roller 22. Between 423, the electric heating wires in the upper heating plate 427 and the lower heating plate 423 are turned on, causing the temperature of the upper heating plate 427 and the lower heating plate 423 to rise. The drive rod 425 is controlled to move the upper mounting plate 424 downward, which in turn moves the upper heating plate 427 downward, so that the upper heating plate 427 and the lower heating plate 423 clamp the ends of the upper packaging film and the lower packaging film, thereby heat-melting the ends of the upper packaging film and the lower packaging film, so that the ends of the upper packaging film and the lower packaging film are bonded. The drive rod 425 is then used to move the upper mounting plate 424 upward and reset it. S2. When packaging and laminating wood-plastic composite boards: According to the width of the wood-plastic composite board, the two hinge seats 5151 on the fixed seat 5143 are controlled to slide in opposite directions to adjust the distance between the two hinge seats 5151. The motor on the hinge seat 5151 causes the hinge plate 5152 to rotate, so that both hinge plates 5152 rotate to a horizontal position. The drive rod 513 is controlled to move the base plate 5141 upward, so that the top of the fixed seat 5143 is flush with the top of the conveyor roller 12. Personnel move the wood-plastic composite board and place it on the two fixed seats 5143, and stack multiple wood-plastic composite boards from bottom to top in sequence, thereby stacking and feeding multiple wood-plastic composite boards. After multiple wood-plastic composite boards are stacked and loaded, the motor on the hinge seat 5151 rotates the hinge plate 5152, so that both hinge plates 5152 rotate to a vertical position, and the two hinge plates 5152 abut against the two sides of the stacked wood-plastic composite boards. The four hinge plates 5152 limit the stacked wood-plastic composite boards for the first time. Then, the drive rod 2 523 moves the slide rail 522 downward along the telescopic rod 2, lowering the height of the slide rail 522, so that the two clamping plates 524 are located on the outer sides of the two ends of the wood-plastic composite boards. The two electric sliders 3 make the two clamping plates 524 slide in opposite directions and move closer to each other, so that the two clamping plates 524 abut against the two ends of the stacked wood-plastic composite boards, thereby limiting the stacked wood-plastic composite boards for the second time and achieving the effect of tidying up and aligning the stacked wood-plastic composite boards. The base plate 5141 is moved upward by the drive rod 513, lifting the stacked wood-plastic composite boards and preventing the bottom wood-plastic composite board from contacting the multiple conveying rollers 12. Two electric sliders cause two sliding blocks 512 to slide on the sliding seat 511, moving the multiple wood-plastic composite boards to the front of the guide frame 21 for loading and transfer. During this process, the weight of the multiple wood-plastic composite boards applies a downward pressure force to the two fixed seats 5143, causing the fixed seats 5143 to abut against the top of the weighing sensor 5144. The force detection signal of the weighing sensor 5144 changes, realizing the weight detection effect of the stacked wood-plastic composite boards, thereby achieving the quality inspection effect of the wood-plastic composite boards to be coated and packaged. After multiple wood-plastic composite boards are moved to the front of the guide frame 21, the base plate 5141 is lowered by the drive rod 513, causing the two hinge plates 5152 to rotate to a horizontal position. Then, the two sliding blocks 512 are slid and reset on the sliding seat 511 to the outside of one side of the guide frame 21 by the two electric sliders, allowing personnel to load the wood-plastic composite boards. The motor on the conveyor frame 11 rotates the shafts of multiple conveyor rollers 12, conveying the stacked wood-plastic composite boards onto the guide frame 21. The stacked wood-plastic composite boards are then guided to multiple guide frames. On the feeding roller 22, the second motor on the guide frame 21 rotates the feeding roller 22, causing the wood-plastic composite board on the multiple feeding rollers 22 to move inward toward the mounting frame 41. When the end of the wood-plastic composite board contacts the inner side of the adhered packaging film, it pushes the packaging film to move. The two positioning rods 4441 rotate around the two rotating shafts 443 respectively, unfolding the upper and lower packaging films. During this process, the control motor 3 rotates the conveyor shaft 32, and the two rubber belts 33 rotate synchronously around the two conveyor shafts 32, driving the multiple support rods 34 respectively. Rotating around the two conveyor shafts 32, the film-covered wood-plastic composite board is moved towards the inside of the top cover 35. When the other end of the wood-plastic composite board moves to the side of the mounting frame 41 near the top cover 35, the upper mounting plate 424 moves down along the spring telescopic rod 426 via the drive rod 3 425, causing the two upper heating plates 427 to abut against the two lower heating plates 423 respectively, heat-melting the upper and lower films and creating two adhesive joints between the upper and lower packaging films. The spring telescopic rod 1 422 and the spring telescopic rod 426... Both rods 426 deform under stress. When the upper cutter 451 and the lower cutter 452 come into contact, they cut the two adhesive joints of the upper and lower packaging films. When the conveyor shaft 32 is rotated by the motor 3, the wood-plastic composite board after being covered with film is moved to the inside of the top cover 35. The first heating plate 36 and the second heating plate 37 are then turned on. The first heating plate 36 and the second heating plate 37 heat the packaging film, causing the packaging film to shrink and cover the outside of the wood-plastic composite board, thus achieving the effect of covering the outside of the stacked wood-plastic composite boards. The control motor 3 rotates the conveyor shaft 32, which drives multiple laminated wood-plastic composite boards to move outward from the top cover 35 onto the conveyor 6. The conveyor 6 then transports the laminated wood-plastic composite boards. During this process, as the wood-plastic composite boards move, the flexible sealing plates 351 at both ends of the top cover 35 deform and cancel the sealing at the ends of the top cover 35. When the wood-plastic composite boards move to the outside or inside of the top cover 35, the flexible sealing plates 351 seal the ends of the top cover 35, achieving a heat insulation effect on the inner wall of the top cover 35 and reducing heat loss.
