Abstract
Description
Technical Field
[0001] This utility model relates to the field of plywood processing technology, specifically a plywood hot pressing molding machine. Background Technology
[0002] Plywood is a type of engineered wood product made by rotary cutting logs into veneers or slicing them into thin sheets, and then gluing them together in an odd number of layers (such as 3 or 5 layers) with adhesive. The fibers of adjacent veneers are arranged perpendicular to each other. This structure results in minimal differences in physical properties in both the longitudinal and transverse directions, and strong stability. The plywood manufacturing process includes rotary cutting, gluing, assembling, cold pressing, hot pressing, and sanding.
[0003] Hot pressing is a crucial step in plywood processing. It increases the bonding strength between boards, thereby improving the plywood's strength, stiffness, stability, and other mechanical properties. However, during hot pressing, glue overflow is common. To ensure plywood quality, this overflow needs to be cleaned up, but currently, it's typically done manually. This method is inefficient, often resulting in incomplete and ineffective cleaning, thus requiring improvement. Utility Model Content
[0004] The purpose of this invention is to provide a plywood hot pressing machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a plywood hot press forming machine, comprising a hot press body, a hot press frame mounted on the top of the hot press body, a lower hot press plate mounted on the top of the hot press body, and an upper hot press plate mounted above the lower hot press plate. The upper hot press plate is fixedly connected to the output end of a hydraulic cylinder at the top of the hot press frame. A drive groove is provided at the edge of the top of the hot press body, and a lead screw is installed inside the drive groove. A servo motor is mounted on the outer wall of the hot press body at the position of the lead screw, and the output end of the servo motor is fixedly connected to the lead screw. A movable block is fitted around the lead screw. A glue removal mechanism is provided on one side of the movable block. The glue removal mechanism includes a glue removal seat, a glue storage box, and a glue scraper. The glue removal seat is located on one side of the movable block, the glue storage box is located inside the glue removal seat, and the glue scraper is fixed to the top of the glue removal seat on one side of the glue storage box.
[0006] Preferably, the upper and lower hot press plates are provided with cavities, and heating rods with equal spacing are installed inside the cavities to facilitate heating of the plywood.
[0007] Preferably, the movable block is threadedly engaged with the lead screw, a small cylinder is installed at the top of the movable block, and the output end of the small cylinder is fixedly connected to the glue removal seat, which facilitates the adjustment of the position of the glue storage box.
[0008] Preferably, a heating block is installed inside the glue removal seat below the glue storage box. The heating block heats the glue storage box to prevent the glue from solidifying.
[0009] Preferably, the glue removal seat has a positioning groove inside, and the inner wall of the positioning groove fits tightly against the outer wall of the glue storage box, which facilitates the positioning of the glue storage box.
[0010] Preferably, a handle is installed on the outer wall of one side of the glue storage box, and the handle has a U-shaped structure to facilitate pulling out the glue storage box.
[0011] Preferably, a limiting guide rod is fixed at the corner position of the top of the upper hot press plate, and the top of the limiting guide rod extends into the limiting hole inside the hot press frame, so as to guide and limit the upper hot press plate and prevent it from deviating.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] During the hot pressing process, glue overflows from the plywood edges. At this time, a small cylinder drives the glue removal mechanism to move horizontally, so that the glue scraper is close to the edge of the plywood. The servo motor drives the lead screw to rotate, so that the movable block moves the glue removal mechanism horizontally along the edge of the plywood. The glue scraper removes the glue, which flows into the glue storage box. The heating block heats the glue storage box to prevent the glue from solidifying. Since there are four sets of glue removal mechanisms distributed on the four sides of the plywood, the automatic glue scraper can quickly remove the overflow glue from the four sides of the plywood, which is highly efficient and has a good cleaning effect.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0022] Please see Figure 1-5 An embodiment of this utility model provides: a plywood hot press forming machine, including a hot press body 1, a hot press frame 2 installed on the top of the hot press body 1, a lower hot press plate 7 installed at the top of the hot press body 1, and an upper hot press plate 6 provided above the lower hot press plate 7. The upper hot press plate 6 is fixedly connected to the output end of the hydraulic cylinder 5 at the top of the hot press frame 2. A drive groove 11 is provided at the edge of the top of the hot press body 1, and a lead screw 12 is installed inside the drive groove 11. A servo motor 13 is installed on the outer wall of the hot press body 1 at the position of the lead screw 12, and the output end of the servo motor 13 is fixedly connected to the lead screw 12. A movable block 14 is fitted on the outside of the lead screw 12.
[0023] The plywood is placed on the lower hot press plate 7, and the hydraulic cylinder 5 drives the upper hot press plate 6 to move down. The upper hot press plate 6 and the lower hot press plate 7 cooperate and act on the plywood through the heating rod 10 inside the cavity 9, so that the plywood is hot-pressed and formed.
[0024] A glue removal mechanism 8 is provided on one side of the movable block 14. The glue removal mechanism 8 includes a glue removal seat 16, a glue storage box 18, and a glue scraper 20. The glue removal seat 16 is located on one side of the movable block 14, the glue storage box 18 is located inside the glue removal seat 16, and the glue scraper 20 is fixed to the top of the glue removal seat 16 on one side of the glue storage box 18.
[0025] During the hot pressing process, glue overflows from the plywood, spilling out from the edges. At this time, the small cylinder 15 drives the glue removal mechanism 8 to move horizontally, so that the glue scraper 20 is close to the edge of the plywood. The servo motor 13 drives the lead screw 12 to rotate, so that the movable block 14 drives the glue removal mechanism 8 to move horizontally along the edge of the plywood. The glue scraper 20 scrapes off the glue, and the glue flows into the glue storage box 18. The heating block 17 heats the glue storage box 18 to prevent the glue from solidifying. Since there are four sets of glue removal mechanisms 8 distributed on the four sides of the plywood, the glue overflow from the four sides of the plywood can be quickly scraped off by automatic glue scraping, which is highly efficient and has a good cleaning effect.
[0026] The upper hot press plate 6 and the lower hot press plate 7 are provided with cavities 9, and heating rods 10 with equal spacing are installed inside the cavities 9;
[0027] The movable block 14 is threadedly engaged with the lead screw 12. A small cylinder 15 is installed at the top of the movable block 14, and the output end of the small cylinder 15 is fixedly connected to the adhesive removal seat 16.
[0028] A heating block 17 is installed inside the glue removal seat 16 below the glue storage box 18;
[0029] In addition, the glue holder 16 has a positioning groove 21 inside, and the inner wall of the positioning groove 21 is in close contact with the outer wall of the glue storage box 18.
[0030] A handle 19 is installed on the outer wall of one side of the glue storage box 18, and the handle 19 has a U-shaped structure;
[0031] Specifically, the glue storage box 18 is pulled out from the positioning groove 21 inside the glue removal base 16 by the handle 19 so that the glue storage box 18 can be removed, making it easier to pour out the scraped glue. Then the glue storage box 18 can be snapped into the positioning groove 21.
[0032] A limiting guide rod 4 is fixed at the corner of the top of the upper hot press plate 6, and the top of the limiting guide rod 4 extends into the limiting hole 3 inside the hot press frame 2.
[0033] In this embodiment, the plywood is first placed on the lower hot press plate 7. The hydraulic cylinder 5 drives the upper hot press plate 6 to move downward. The upper and lower hot press plates 6 and 7 cooperate and act on the plywood through the heating rod 10 inside the cavity 9, so that the plywood is hot-pressed and formed. Then, during the hot pressing process, there is glue overflow from the edge of the plywood. At this time, the small cylinder 15 drives the glue removal mechanism 8 to move horizontally, so that the glue scraper 20 is close to the edge of the plywood. The servo motor 13 drives the lead screw 12 to rotate, so that the movable block 14 drives the glue removal mechanism 8 to stick to the glue. The plywood moves horizontally along its edge, and the glue scraper 20 scrapes off the glue, which flows into the glue storage box 18. The heating block 17 heats the glue storage box 18 to prevent the glue from solidifying. Since the glue removal mechanism 8 has four sets distributed on the four sides of the plywood, the automatic glue scraper can quickly remove the excess glue from the four sides of the plywood, which is efficient and has a good cleaning effect. Furthermore, the glue storage box 18 can be pulled out from the positioning groove 21 inside the glue removal seat 16 by the handle 19, so that the glue storage box 18 can be removed and the scraped glue can be poured out. Then the glue storage box 18 can be inserted into the positioning groove 21.
[0034] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
