Abstract
Description
Technical Field
[0001] This utility model relates to the field of poplar and eucalyptus hybrid layer production technology, and in particular to a poplar and eucalyptus hybrid layer lamination pressing device. Background Technology
[0002] Poplar-eucalyptus hybrid laminated lumber is a composite material formed by pressing poplar and eucalyptus veneers or thin sheets together using certain processes and equipment. During the production and processing of poplar-eucalyptus hybrid laminated lumber, a pressing device is required to perform the pressing process.
[0003] Existing eucalyptus and poplar mixed laminated timber lamination equipment involves placing the timber sheets on a cold press and aligning them for lamination. However, because it's inconvenient to automatically align the timber sheets before lamination, the sheets are not perfectly aligned during pressing. This results in uneven pressure distribution across the sheets, causing pressure concentration in localized areas and hindering uniform adhesive curing. Consequently, the bonding strength between the sheets becomes inconsistent, potentially leading to weak adhesion or delamination, thus reducing the practicality of the equipment. Therefore, this invention proposes a eucalyptus and poplar mixed laminated timber lamination device to solve these problems. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a pressing device for hybrid laminated poplar and eucalyptus wood, which solves the problem in the prior art where it is inconvenient to automatically align the hybrid laminated poplar and eucalyptus wood before pressing, resulting in unevenness of the wood during pressing. This makes it difficult to evenly distribute the pressure applied by the cold press on each board, causing the boards to shift and the pressure to concentrate in local areas. Consequently, the adhesive cannot cure evenly, leading to uneven bonding strength between the boards and potentially resulting in localized poor adhesion or delamination.
[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a pressing device for hybrid laminated timber of poplar and eucalyptus, including a base plate, side plates installed on both sides of the top of the base plate, a top plate installed on the top of the side plates, a hydraulic cylinder installed on the top of the top plate, the bottom end of the hydraulic cylinder extending to the bottom of the top plate, a pressing plate installed at the output end of the hydraulic cylinder, guide holes penetrating through both ends of the top plate, guide rods penetrating through the guide holes, the bottom ends of the guide rods connecting to the top of the pressing plate, a first alignment mechanism provided at the rear end above the base plate, and a second alignment mechanism provided on the inner side of the side plates;
[0006] The first alignment mechanism includes a mounting block, a movable plate, and a transmission structure. The mounting block is mounted on the rear end of the base plate, the movable plate is mounted on the inner side of the mounting block, and the transmission structure is provided at the rear end of the mounting block.
[0007] A further improvement is made in that the transmission structure includes a mounting bracket, a rotating wheel, a driving gear, a driven gear ring, a threaded sleeve, a screw, and a limiting assembly. The mounting bracket is installed at the rear end of the mounting block. A rotating wheel is installed at one end of the mounting bracket. A driving gear is installed on the inner side of the mounting bracket. One end of the rotating wheel is connected to one end of the driving gear. A driven gear ring meshes with one side of the driving gear. A threaded sleeve is provided through the interior of the driven gear ring. A screw is provided through the interior of the threaded sleeve. One end of the screw extends to the inner side of the mounting block and is connected to one side of the movable plate.
[0008] A further improvement is made in that: the limiting component includes a limiting rail, a limiting block, a limiting hole, and a limiting rod. The limiting rail is installed at the rear end of the mounting block. A limiting block is provided inside the limiting rail. One end of the limiting block is connected to the outside of the threaded sleeve. Limiting holes are opened through both ends of the mounting block. A limiting rod is provided through the inside of the limiting hole. One end of the limiting rod is connected to one end of the movable plate.
[0009] A further improvement is that two limiting blocks are provided inside the limiting rail, and the two limiting blocks are symmetrically distributed about the central axis between the limiting rails.
[0010] A further improvement is that the cross-section of the limiting hole is larger than the cross-section of the limiting rod, and the limiting hole and the limiting rod form a sliding structure.
[0011] A further improvement is made in that: the second alignment mechanism includes a placement hole, a moving plate, a servo motor, a threaded rod, and a threaded sleeve.

A threaded sleeve is arranged on the outer wall of the threaded rod, and the groove can guide the threaded sleeve. The top end of the threaded sleeve is connected to the bottom end of the moving plate.
[0012] The beneficial effects of this utility model are as follows: By providing a first alignment mechanism at the rear end of the base plate, and utilizing the mutual cooperation between the mounting block, movable plate, mounting frame, rotating wheel, driving gear, driven gear ring, screw sleeve, screw rod, limiting rail, limiting block, limiting hole, and limiting rod of the first alignment mechanism, the movable plate can be used to align the stacked materials. Simultaneously, the position of the movable plate can be adjusted to align materials of different sizes, ensuring that the materials of different sizes are positioned directly above the base plate during pressing. This results in more uniform stacking of the materials and ensures that the pressure applied by the cold press is evenly distributed across each material, preventing misalignment due to material position. The offset causes pressure to concentrate in a localized area, thereby ensuring uniform curing of the adhesive and guaranteeing consistent bonding strength between the boards. This prevents localized weak bonding or delamination, significantly improving the practicality of the device during use. A second alignment mechanism is provided on the inner side of the side plate. The interaction between the placement hole, moving plate, servo motor, threaded rod, and threaded sleeve of the second alignment mechanism drives two moving plates to move. These two moving plates align the two sides of the material during pressing, resulting in a neater pressing process and greatly improving the overall neatness of the device during use.

[0018] To deepen the understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.
[0019] according to Figure 1 ,2 As shown in Figures 3 and 4, this embodiment proposes a pressing device for hybrid laminated timber of Populus euphratica and Eucalyptus spp., including a base plate 1, side plates 2 installed on both sides of the top of the base plate 1, a top plate 3 installed on the top of the side plates 2, a hydraulic cylinder 4 installed on the top of the top plate 3, the bottom end of the hydraulic cylinder 4 extending to the bottom of the top plate 3, a pressing plate 5 installed at the output end of the hydraulic cylinder 4, guide holes 6 penetrating through both ends of the top plate 3, guide rods 7 penetrating through the interior of the guide holes 6, the bottom end of the guide rods 7 connecting to the top of the pressing plate 5, a first alignment mechanism provided at the rear end above the base plate 1, and a second alignment mechanism provided on the inner side of the side plates 2.
[0020] The first alignment mechanism includes a mounting block 13, a movable plate 14, and a transmission structure. The mounting block 13 is mounted on the rear end of the base plate 1. The movable plate 14 is mounted on the inner side of the mounting block 13. The transmission structure is provided at the rear end of the mounting block 13. The transmission structure includes a mounting frame 15, a rotating wheel 16, a driving gear 17, a driven gear ring 18, a threaded sleeve 19, a screw 20, and a limiting assembly. The mounting frame 15 is mounted on the rear end of the mounting block 13. The rotating wheel 16 is mounted on one end of the mounting frame 15. A drive gear 17 is mounted on the side. One end of the rotating wheel 16 is connected to one end of the drive gear 17. A driven gear ring 18 meshes with one side of the drive gear 17. A threaded sleeve 19 is provided through the interior of the driven gear ring 18. A screw 20 is provided through the interior of the threaded sleeve 19. One end of the screw 20 extends to the inner side of the mounting block 13 and is connected to one side of the movable plate 14. In use, rotating the rotating wheel 16 drives the drive gear 17 to rotate. Due to the interaction between the drive gear 17 and the driven gear ring 18... The components mesh with each other, so under the limitation of the limiting rail 21 and the limiting block 22, the driven gear ring 18 drives the screw sleeve 19 to rotate. Since the screw sleeve 19 and the screw 20 are threadedly connected, the screw 20 is driven to move. Then, under the limitation of the limiting hole 23 and the limiting rod 24, the screw 20 drives the movable plate 14 to move, moving the movable plate 14 to the appropriate position. At this time, the operator can feed the material, so that the rear end of the material is in contact with the movable plate 14, and the material is longitudinally aligned during feeding. Simultaneously, the position of the movable plate 14 can be adjusted to align plates of different sizes, ensuring that the plates are directly above the base plate 1 during pressing. This makes the pressed materials more neat and evenly distributed, preventing pressure from being concentrated in localized areas due to plate misalignment. This allows the adhesive to cure evenly, ensuring uniform bonding strength between the plates and preventing localized poor adhesion or delamination. This greatly improves the practicality of the device during use.
[0021] The limiting assembly includes a limiting rail 21, a limiting block 22, a limiting hole 23, and a limiting rod 24. The limiting rail 21 is installed at the rear end of the mounting block 13. A limiting block 22 is disposed inside the limiting rail 21. One end of the limiting block 22 is connected to the outside of the threaded sleeve 19. Limiting holes 23 are formed through both ends of the mounting block 13. A limiting rod 24 is disposed inside the limiting hole 23. One end of the limiting rod 24 is connected to one end of the movable plate 14. Two limiting blocks 22 are disposed inside the limiting rail 21. The position blocks 22 are symmetrically distributed about the central axis between the limiting rails 21. The cross-section of the limiting hole 23 is larger than the cross-section of the limiting rod 24. The limiting hole 23 and the limiting rod 24 form a sliding structure. In use, the mutual cooperation between the limiting rails 21 and the limiting blocks 22 can limit the movement of the threaded sleeve 19, making the threaded sleeve 19 more stable when rotating. The mutual cooperation between the limiting hole 23 and the limiting rod 24 can limit the movement of the movable plate 14, making the movable plate 14 more stable when moving.
[0022] The second alignment mechanism includes a placement hole 8, a moving plate 9, a servo motor 10, a threaded rod 11, and a threaded sleeve 12. The placement hole 8 is located inside the side plate 2, and the moving plate 9 is installed inside the placement hole 8. The servo motor 10 is mounted on both sides of the base plate 1. A groove is formed inside the base plate 1, and the threaded rod 11 is installed inside the groove. The output end of the servo motor 10 is connected to one end of the threaded rod 11. A threaded sleeve 12 is provided on the outer wall of the threaded rod 11. The groove can guide the threaded sleeve 12. The top end of the threaded sleeve 12 is connected to the bottom end of the moving plate 9. In use, the servo motor 10 is started to drive the threaded rod 11 to rotate, thus driving the threaded sleeve 12 to move, which in turn drives the moving plate 9 to move. The two moving plates 9 are used to move the assemblies and align them laterally, making the assemblies more neat when pressed. The two moving plates 9 are also used to align the two sides of the assemblies during pressing, making the assemblies more neat when pressed, thereby greatly improving the neatness of the device during use.
[0023] Working principle: The operator first rotates the rotating wheel 16 to drive the driving gear 17 to rotate. Since the driving gear 17 and the driven gear ring 18 mesh with each other, under the limitation of the limiting rail 21 and the limiting block 22, the driven gear ring 18 drives the threaded sleeve 19 to rotate. Since the threaded sleeve 19 and the screw 20 are connected by threads, the screw 20 is moved. Then, under the limitation of the limiting hole 23 and the limiting rod 24, the screw 20 drives the movable plate 14 to move. The movable plate 14 is moved to the appropriate position, at which time the operator can feed the material, so that the rear end of the material is in contact with the movable plate 14. The material is longitudinally aligned during feeding. After aligning the materials, the servo motor 10 is started to drive the threaded rod 11 to rotate, which in turn drives the threaded sleeve 12 to move, and then drives the moving plate 9 to move. The two moving plates 9 are used to move the material and align it laterally, so that the material is more neat when pressed. Then the reverse wheel 16 drives the movable plate 14 to move backward, and moves the movable plate 14 out from under the pressing plate 5. Then the servo motor 10 is started to reverse, and the moving plate 9 is moved into the placement hole 8. At this time, the hydraulic cylinder 4 is started, and under the guidance of the guide hole 6 and the guide rod 7, the pressing plate 5 is moved downward, and the pressing plate 5 is used to press the poplar and eucalyptus mixed layer material.
