Description

Technical Field

[0001] This utility model relates to the field of hot pressing technology for composite boards, specifically a hot pressing device for wood composite boards. Background Technology

[0002] Wood-based composite boards are engineered wood products made by bonding various wood materials together with adhesives. They are mainly composed of wood units (such as veneer, fiber, and wood shavings) and adhesives. Veneer is a thin sheet obtained by rotary cutting or slicing wood; for example, veneer is widely used in plywood production. Fiber is the fine wood fiber obtained after separating wood fibers; it is commonly used in fiberboard production. Wood shavings are the scraps made from wood processing residues and are used in particleboard production. Adhesives mainly include urea-formaldehyde resin, phenolic resin, and melamine-formaldehyde resin. These adhesives can tightly bind the wood units together. Wood-based composite boards require a hot-pressing device to heat-press them during processing.

[0003] In existing technology, composite boards are placed in an extrusion groove, and a cylinder drives a pressure plate to press the template in the extrusion groove, thus bonding the composite boards together.

[0004] However, in actual use, because the composite wood boards are pressed together by a hot press, the surface temperature of the pressed wood boards can be too high, which can easily burn the workers and make it inconvenient for the workers to replace the wood boards. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hot pressing device for wood composite boards, which solves the problem that in actual use, the surface temperature of the pressed wood boards is too high due to the hot pressing process, which can easily burn workers and make it inconvenient for workers to replace the boards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wood composite board hot pressing device, comprising a workbench, a fixed frame fixedly connected to the top of the workbench, a hot pressing plate provided on one side of the top of the fixed frame, a cooling shell installed on the other side of the fixed frame, the top of the cooling shell movably connected to the top of the workbench, a fan embedded in the top of the inner wall of the cooling shell, a bracket fixedly connected to the inner wall of the fixed frame, the bottom of the bracket abutting against the top of the workbench, and a driving device installed on the outer wall of the cooling shell.

[0007] Preferably, the driving device includes an electric slider, an electric slide rod is movably connected to the inner wall of the electric slider, and the outer wall of the electric slide rod is fixedly connected to the outer wall of the worktable.

[0008] Preferably, a hydraulic rod is fixedly connected to the top of the hot press plate, a fixed frame is fixedly connected to the top of the hydraulic rod, the bottom of the fixed frame is slidably engaged with the top of the workbench, a sliding rod is fixedly connected to the outer wall of the hot press plate, and the outer wall of the sliding rod is movably connected to the inner wall of the fixed frame.

[0009] Preferably, a connecting frame is fixedly connected to the outer wall of the fixed frame, a connecting block is fixedly connected to the outer wall of the connecting frame, a connecting rod is rotatably connected to the outer wall of the connecting block via a pin, a turntable is rotatably connected to the end of the connecting rod via a pin, and the bottom of the turntable is rotatably connected to the top of the worktable via a bearing.

[0010] Preferably, the top of the workbench has a groove, the inner wall of the groove is slidably engaged with a rod, the top of the rod is fixedly connected to a top plate, and the outer wall of the rod is sleeved with a spring, which is pressed against the top plate and the groove. Beneficial effects

[0011] This utility model provides a hot pressing device for wood composite boards. It has the following advantages: Through the cooperation of a hot pressing plate, a cooling shell, and a fan, after the composite template is pressed, the cooling shell is moved above the wood board, and the fan blows air onto the pressed wood board, rapidly cooling it. This facilitates subsequent processing of the wood board and solves the problem that when composite boards are bonded using a hot pressing plate, the surface temperature of the pressed wood board becomes too high, easily burning workers and making it inconvenient for workers to replace the boards.

[0012] By coordinating the turntable, connecting rod, and connecting block, the turntable is rotated during the hot pressing of the composite wood board. This causes the connecting rod to drive the connecting block to move the connecting frame and the fixed frame on the worktable, aligning the hot pressing plate with the composite wood board and hot pressing it into shape. This solves the problem of inconvenience in changing the template after hot pressing the wood board in the existing device. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In actual use, because composite wood boards are pressed together by hot press plates, the surface temperature of the pressed wood boards can be too high, which can easily burn workers and make it inconvenient for workers to replace the wood boards.

[0017] In view of this, the present invention provides a hot pressing device for wood composite boards, which solves the problem that in actual use, since the composite boards are pressed by a hot pressing plate, the surface temperature of the pressed boards is too high, which can easily burn the workers and make it inconvenient for the workers to replace the boards.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] Example 1: By Figure 1-4 It is known that a wood composite board hot pressing device includes a workbench 1, a fixed frame 2 is fixedly connected to the top of the workbench 1, a hot pressing plate 4 is provided on one side of the top of the fixed frame 2, a cooling shell 10 is installed on the other side of the fixed frame 2, the top of the cooling shell 10 is movably connected to the top of the workbench 1, a fan 11 is embedded in the top of the inner wall of the cooling shell 10, a bracket 3 is fixedly connected to the inner wall of the fixed frame 2, the bottom of the bracket 3 is pressed against the top of the workbench 1, and a driving device is installed on the outer wall of the cooling shell 10. In the specific implementation process, it is worth noting that the size of the fixed frame 2 is designed according to the size of the composite wood board. At the same time, the internal fixed connection bracket 3 will support the composite wood board to ensure the stability of the template during hot pressing. Meanwhile, when hot pressing the wood board, the glue needs to be heated to a certain temperature to ensure that the wood boards are bonded together. After hot pressing is completed, the cooling shell 10 is moved above the wood board and the fan 11 is turned on to cool down the hot-pressed wood board, which makes it convenient for the staff to handle in the subsequent process and also speeds up the rapid cooling of the glue between the wood boards. Furthermore, the driving device includes an electric slider 12, an electric slide rod 13 is movably connected to the inner wall of the electric slider 12, and the outer wall of the electric slide rod 13 is fixedly connected to the outer wall of the worktable 1. In the specific implementation process, it is worth noting that the electric slider 12 and the electric slide rod 13 are electrically connected and used in pairs. The operator can control the electric slider 12 to move on the outer wall of the electric slide rod 13 through an external controller to ensure that the cooling shell 10 can move above the wooden board. The models of the electric slide rod 13 and the electric slider 12 are not limited, as long as they meet the actual use conditions. Furthermore, a hydraulic rod 5 is fixedly connected to the top of the hot press plate 4, a fixed frame 6 is fixedly connected to the top of the hydraulic rod 5, the bottom of the fixed frame 6 is slidably engaged with the top of the workbench 1, and a slide rod 14 is fixedly connected to the outer wall of the hot press plate 4, and the outer wall of the slide rod 14 is movably connected to the inner wall of the fixed frame 6. In the specific implementation process, it is worth noting that multiple hydraulic rods 5 are provided to ensure that the hot press plate 4 is subjected to uniform force when pressing the wooden board. The hydraulic rods 5 are connected by a synchronizer to ensure that each hydraulic rod 5 can work synchronously, so that the hot press plate 4 is stable when working. All the hydraulic rods 5 are controlled by hydraulic cylinders, and the slide bar 14 can ensure the stability of the hot press plate 4 when lifting and lowering.

[0020] Example 2: From Figure 1-4 It can be seen that the outer wall of the fixed frame 6 is fixedly connected to the connecting frame 7, the outer wall of the connecting frame 7 is fixedly connected to the connecting block 18, the outer wall of the connecting block 18 is rotatably connected to the connecting rod 19 through the pin, the end of the connecting rod 19 is rotatably connected to the turntable 8 through the pin, and the bottom of the turntable 8 is rotatably connected to the top of the worktable 1 through the bearing. In the specific implementation process, it is worth noting that a motor is installed at the bottom of the turntable 8 and controlled by a controller. When the hot press plate 4 is to hot press the template, the motor will drive the turntable 8 to rotate 180 degrees, so that the connecting rod 19 drives the connecting block 18 to push the connecting frame 7 to move on the worktable 1, and move the hot press plate 4 above the wooden board, so that the hot press plate 4 can accurately press the wooden board. Furthermore, a groove 15 is provided on the top of the workbench 1, and a rod 16 is slidably engaged with the inner wall of the groove 15. A top plate 9 is fixedly connected to the top of the rod 16, and a spring 17 is sleeved on the outer wall of the rod 16. The spring 17 is pressed against the top plate 9 and the groove 15. In the specific implementation process, it is worth noting that when the wooden board is squeezed, the top plate 9 will move into the groove 15 and the spring 17 will contract. After the wooden board is squeezed, the pressure on the top plate 9 will disappear and the wooden board will be pushed out of the fixed frame 2 under the compression of the spring 17. This makes it more convenient for workers to replace the wooden board.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
