Description

Technical Field

[0001] This utility model relates to the field of laminated veneer technology, specifically to a gluing device for the production of laminated veneer. Background Technology

[0002] Laminated veneer lumber (LVL) is a material made by laminating thick veneers along the grain direction, hot-pressing and gluing them together, and then sawing them. Due to its unique advantages in specifications, strength, and performance, LVL has a very wide range of applications and can be divided into non-structural and structural types according to its use. Structural LVL is further divided into small-diameter structural lumber and large-diameter structural lumber.

[0003] Currently, laminated veneer lumber requires gluing during the production process. However, existing gluing equipment can only apply glue to products smaller than or equal to the specified size due to its fixed dimensions. For products larger than the specified size, multiple gluing operations are required, which affects work efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gluing equipment for the production of veneer laminated lumber.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A gluing device for producing laminated veneer lumber includes a base plate, a top plate on top of the base plate, clamping plates that move synchronously in opposite directions on the top surface of the base plate, a connecting plate at the bottom of the top plate that can move horizontally and vertically, a reciprocating housing at the bottom of the connecting plate, and a gluing roller protruding from the bottom of the housing that is rotatably mounted inside the housing. The horizontal movement direction of the connecting plate is perpendicular to the movement direction of the two clamping plates, and the movement direction of the housing is parallel to the movement direction of the two clamping plates.

[0007] Preferably, the distance that the box body drives the glue-applying roller to move in one direction is always greater than the width of the veneer laminate, and the distance that the connecting plate moves horizontally during the time it takes for the glue-applying roller to move from its farthest point to contact the veneer laminate is the length of the glue-applying roller.

[0008] Preferably, the center point of the connecting plate is located at the midpoint of the two clamping plates, and a drive motor for driving the box to reciprocate is installed at the center of the top of the connecting plate.

[0009] Preferably, the drive motor has a turntable located inside the connecting plate via a transmission rod at its three output ends. The bottom of the turntable has several fixed rods. A sliding plate connected to the housing is also slidably arranged inside the connecting plate, and both sides of the sliding plate have toothed grooves that mesh with the several fixed rods.

[0010] Preferably, a second drive motor is installed on one side of the top plate, and a lead screw located inside the top plate is driven at the output end of the second drive motor. A movable block that penetrates the top plate and is slidably connected to the top plate is threaded on the lead screw, and a cylinder connected to a connecting plate is provided at the bottom of the movable block.

[0011] Preferably, a drive motor is installed on one side of the base plate, and the output end of the drive motor is provided with a bidirectional threaded rod located inside the base plate. The bidirectional threaded rod is symmetrically threaded with threaded blocks that penetrate the base plate and are slidably connected to the base plate. The top of the threaded blocks is connected to the clamping plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses clamps to hold the front and rear sides of laminated veneer lumber. A connecting plate descends, causing a gluing roller to come into contact with the laminated veneer lumber. The reciprocating motion of the housing drives the gluing roller to move, thereby applying glue to the surface of the laminated veneer lumber. At the same time, the housing drives the gluing roller to move along the two clamps, which, combined with the horizontal movement of the housing, allows for rapid and comprehensive gluing of laminated veneer lumber of different sizes. It has high practical value. Attached Figure Description

Detailed Implementation

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] like Figure 1 As shown, this utility model discloses a gluing device for producing laminated veneer lumber, comprising a base plate 1, a top plate 2 on top of the base plate 1, the base plate 1 and the top plate 2 forming a U-shaped mounting frame, and a drive motor 3 mounted on one side of the base plate 1. Figure 4 As shown, the output end of the drive motor 3 is equipped with a bidirectional threaded rod 16 located inside the base plate 1. The bidirectional threaded rod 16 is symmetrically threaded with threaded blocks 17 that penetrate the base plate 1 and are slidably connected to it. The top of the threaded blocks 17 is equipped with a clamping plate 18 located on the top surface of the base plate 1. The drive motor 3 drives the two threaded blocks 17 to move synchronously in opposite directions, thereby driving the two clamping plates 18 to move synchronously in opposite directions. In this way, the clamping plates 18 can clamp veneer laminates of different widths, increasing the applicability of the equipment. The height of the clamping plate 18 is less than the thickness of the veneer laminate, so that the glue will not be applied to the clamping plate 18 during application, thus avoiding glue waste.

[0022] A drive motor 4 is installed on one side of the top plate 2, such as Figure 2 As shown, the output end of the drive motor 4 is equipped with a lead screw 9 located inside the top plate 2. The lead screw 9 is threaded with a moving block 8 that passes through the top plate 2 and is slidably connected to the top plate 2. A cylinder 5 is provided at the bottom of the moving block 8, and a connecting plate 10 is provided at the bottom of the cylinder 5. The drive motor 4 drives the moving block 8 to move, thereby driving the cylinder 5 and the connecting plate 10 to move horizontally. At the same time, the cylinder 5 drives the connecting plate 10 to rise and fall.

[0023] The center point of the connecting plate 10 is located at the midpoint of the two clamping plates 18, and a drive motor 6 is installed at the top center of the connecting plate 10 to ensure that the veneer laminate is located directly below the connecting plate 10. Figure 3 As shown, the output end of the drive motor 6 is driven by a transmission rod to a turntable 12 located in the connecting plate 10. Several fixed rods 13 are provided at the bottom of the turntable 12. A sliding plate 14 connected to the housing 11 is also slidably arranged in the connecting plate 10. Both sides of the sliding plate 14 are provided with toothed grooves 15 that mesh with the several fixed rods 13. The housing 11 is provided at the bottom of the sliding plate 14. A glue-applying roller 7 protruding from the bottom of the housing 11 is rotatably arranged in the housing 11. The drive motor 6 drives the fixed rods 13 on the turntable 12 to mesh with the toothed grooves 15 on both sides, thereby realizing the reciprocating motion of the sliding plate 14 in the connecting plate 10, and thus realizing the reciprocating motion of the housing 11 and the glue-applying roller 7.

[0024] like Figure 1 As shown, the horizontal movement direction of the connecting plate 10 is perpendicular to the movement direction of the two clamping plates 18, and the movement direction of the housing 11 is parallel to the movement direction of the two clamping plates 18. This ensures that the housing 11 will not pull the veneer laminate material when it drives the glue-applying roller 7 to apply glue, because the clamping plates 18 are in a limiting position, thus ensuring the stability of the glue-applying work. The glue-applying roller 7 is parallel to the lead screw 9, ensuring the stable rotation of the glue-applying roller 7 and the stable operation of the glue-applying work. The distance that the housing 11 drives the glue-applying roller 7 to move in one direction is always greater than the width of the veneer laminate material, and the distance that the connecting plate 10 moves horizontally from the farthest point to the point of contact with the veneer laminate material is the length of the glue-applying roller 7. The speed of the horizontal movement of the connecting plate 10 is changed by controlling the speed of the drive motor 4, thus making it suitable for more situations.

[0025] In use, the laminated veneer lumber is placed between two clamping plates 18. The drive motor 3 drives the two clamping plates 18 to hold the laminated veneer lumber. The drive motor 4 drives the glue-applying roller 7 to be positioned on one side of the laminated veneer lumber, and the cylinder 5 drives the glue-applying roller 7 to descend and come into contact with the laminated veneer lumber. The drive motor 6 drives the housing 11 and the glue-applying roller 7 to move, so that the glue-applying roller 7 applies glue to the surface of the laminated veneer lumber. When the glue-applying roller 7 moves to the furthest point from the laminated veneer lumber, the drive motor 4 drives the glue-applying roller 7 to move horizontally. The length of horizontal movement of the glue-applying roller 7 during the time it takes to move from the furthest point to the point of contact with the laminated veneer lumber is the length of the glue-applying roller 7. The glue-applying work is completed by repeating the cycle.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
