Description

Technical Field

[0001] This utility model relates to the field of laminated wood processing technology, and in particular to a laminated wood and a laminating machine. Background Technology

[0002] Laminated wood, also known as glued laminated timber, is a type of engineered wood product. In the processing of laminated wood, layers of wood are typically placed in a laminator, which applies pressure and a certain temperature to the layers of wood, causing the adhesive to cure and thus firmly bonding the layers of material together.

[0003] Most existing small laminating machines use bolts to fix the pressure plates to the hot press plate, which makes it easy to replace and maintain the pressure plates on the hot press plate later. However, the vibration force generated by the pressure plate during operation is transmitted to the bolts, which can easily cause the bolts to loosen. This can lead to an unstable connection between the pressure plate and the hot press plate, thus affecting the curing efficiency of the laminated wood. Utility Model Content

[0004] Therefore, it is necessary to provide a laminated wood and a laminator to address the problem that the vibration force generated by the press plate during operation can be transmitted to the bolts, which can easily lead to loosening of the bolts and instability of the connection between the press plate and the hot press plate.

[0005] The system includes: two hot press frames and a pressure plate. The inner wall of the pressure plate is threaded with several bolts, the surfaces of which are threaded to the inner wall of the hot press frame. An anti-loosening mechanism includes fixed blocks evenly distributed on the surface of the hot press frame. The inner wall of each fixed block is slidably connected to a plunger, a damping rod, a pressure block, and a positioning rod. The surface of the damping rod engages with the inner wall of the plunger, the bottom of the pressure block contacts the top of the damping rod, and the surface of the positioning rod is slidably connected to the inner walls of the damping rod and the pressure block. Through the cooperation of the fixed blocks, plungers, damping rods, pressure blocks, and positioning rods, one end of the bolt is locked, ensuring the bolt is stably threaded within the pressure plate and hot press frame. This prevents the bolt from loosening during operation and ensures the pressure plate is stably installed on the hot press frame, thereby guaranteeing the curing efficiency of the laminated wood.

[0006] In one embodiment, a retaining pad is fixedly connected to the top of the fixing block, and one side of the retaining pad contacts one side of the pressing block.

[0007] In one embodiment, a coil spring is fixedly connected to the surface of the pressure block, and the other end of the coil spring is fixedly connected to the upper end of the inner wall of the fixed block. The interaction between the coil spring and the retaining pad increases the resistance to the rotation of the pressure block, ensuring that the pressure block stably contacts the top of the damping rod, thereby ensuring stable locking of the bolt and ensuring that the pressure plate is stably installed on the hot press frame.

[0008] In one embodiment, a limiting ring is fixedly connected to the surface of the damping rod, and the surface of the limiting ring is slidably connected to the inner wall of the fixed block. The limiting ring limits the upward movement of the damping rod, preventing it from dislodging from the fixed block.

[0009] In one embodiment, the surface of the fixing block is rolled with ball bearings, and the surface of the ball bearings is rolled to the surface of the pressure plate. The ball bearings guide the pressure plate onto the hot press frame, ensuring that the threaded holes on the pressure plate and the hot press frame are aligned.

[0010] In one embodiment, the inner wall of the pressure block has a positioning groove, and the surface of the positioning rod is slidably connected to the inner wall of the positioning groove. The positioning groove is used to limit the upward movement of the positioning rod and prevent the positioning rod from dislodging from the pressure block.

[0011] In one embodiment, one end of the plunger is fixedly connected to a connecting rope, and the other end of the connecting rope is fixedly connected to the surface of the fixing block.

[0012] A laminated wood comprising: laminated wood, the bottom of which contacts the top of one of the pressure plates.

[0013] Beneficial effects 1. By cooperating with the fixing block, plug, damping rod, pressure block and positioning rod, one end of the bolt is locked, thereby ensuring that the bolt is stably threaded in the pressure plate and hot press frame, avoiding the bolt from loosening during operation. Locking the bolt ensures that the pressure plate is stably installed on the hot press frame, thereby ensuring the curing efficiency of the laminated wood. 2. The interaction between the coil spring and the retaining pad increases the resistance to the rotation of the pressure block, ensuring that the pressure block stably contacts the top of the damping rod, thereby ensuring the stable locking of the bolt and ensuring that the pressure plate is stably installed on the hot press frame.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figures 1-5 This invention describes the laminated wood and the laminating machine.

[0019] In one embodiment, a laminator includes: two hot press frames 100 and a pressure plate 200. The inner wall of the pressure plate 200 is threaded with a plurality of bolts 400, and the surfaces of the bolts 400 are threaded to the inner wall of the hot press frame 100. The anti-loosening mechanism 500 includes fixing blocks 501 that are fixedly connected to the surface of the hot press frame 100 and are evenly distributed. The inner wall of the fixing blocks 501 is slidably connected with a plunger 502, a damping rod 503, a pressure block 504, and a positioning rod 505. The surface of the damping rod 503 is engaged with the inner wall of the plunger 502. The bottom of the pressure block 504 contacts the top of the damping rod 503. The surface of the positioning rod 505 is slidably connected to the inner walls of the damping rod 503 and the pressure block 504 in sequence.

[0020] It should be noted that a laminator typically consists of a hot press frame 100, a press plate 200, a frame, a hydraulic mechanism, a heating mechanism, and a PLC controller. The model of the laminator is MH3848*100T.

[0021] Select suitable wood veneers and cut and splice them according to product requirements, ensuring the moisture content of the veneers is within a suitable range to guarantee the bonding effect of the adhesive. Apply the adhesive evenly to the surface of the wood veneers, and then assemble the veneers according to a specific grain direction and number of layers. During assembly, pay attention to the alignment and stacking order of the veneers to ensure the strength and stability of the laminated wood. Place the assembled wood on top of one of the pressure plates 200 on the laminator. Manually activate the hydraulic mechanism to bring the two hot-press frames 100 closer together, applying initial pressure to the wood. Manually activate the heating mechanism to gradually raise the temperature of the pressure plate 200 to the predetermined hot-pressing temperature. After reaching the predetermined hot-pressing temperature, maintain the pressure and temperature for a period of time to allow the adhesive to fully cure. After the pressure holding period, stop heating and allow the pressure plate 200 to cool naturally or through the cooling system. When the temperature drops to a certain level, slowly release the pressure, open the pressure plate 200, remove the hot-pressed wood boards from the laminator, and allow them to cool and stack.

[0022] In this embodiment, the pressure plate 200 to be used is clamped on the surface of the hot press frame 100. The bolt 400 is threaded into the pressure plate 200 and the hot press frame 100 using an electric wrench. The plug 502 is slid into the fixing block 501 and abuts against one end of the bolt 400. The damping rod 503 is pushed down and clamped in the plug 502. The pressure block 504 is pushed so that the bottom of the pressure block 504 abuts against the top of the damping rod 503. The positioning rod 505 is pushed down and slides into the damping rod 503 and the fixing block 501, so that the plug 502 is locked in the fixing block 501, and the pressure plate 200 is stably installed on the hot press frame 100.

[0023] like Figure 3 As shown, a retaining pad 506 is fixedly connected to the top of the fixing block 501. One side of the retaining pad 506 contacts one side of the pressure block 504. A coil spring 507 is fixedly connected to the surface of the pressure block 504. The other end of the coil spring 507 is fixedly connected to the upper end of the inner wall of the fixing block 501.

[0024] The 506 baffle is a silicone rubber component with excellent high temperature resistance and high elasticity.

[0025] In this embodiment, one side of the retaining pad 506 is pulled to deform, and the elastic force of the coil spring 507 pushes the pressure block 504 to rotate, so that one side of the pressure block 504 can smoothly pass over one side of the retaining pad 506 and abut against the other side of the retaining pad 506, loosening the restriction on the retaining pad 506. The high elasticity of the retaining pad 506 causes it to reset, so that one side of the retaining pad 506 abuts against the other side of the pressure block 504.

[0026] like Figure 4-5As shown, a limiting ring 509 is fixedly connected to the surface of the damping rod 503. The surface of the limiting ring 509 is slidably connected to the inner wall of the fixing block 501. A positioning groove 511 is provided on the inner wall of the pressure block 504. The surface of the positioning rod 505 is slidably connected to the inner wall of the positioning groove 511. One end of the plug 502 is fixedly connected to a connecting rope 510. The other end of the connecting rope 510 is fixedly connected to the surface of the fixing block 501. A ball bearing 508 is slidably connected to the surface of the fixing block 501. The surface of the ball bearing 508 is slidably connected to the surface of the pressure plate 200.

[0027] Bolt 400, fixing block 501, plug 502, damping rod 503, pressure block 504, positioning rod 505, coil spring 507, and limiting ring 509 are all high-temperature alloy components with excellent high-temperature resistance, high strength and toughness. They can absorb and disperse energy when subjected to vibration loads, reducing the impact of vibration on bolt 400, fixing block 501, plug 502, damping rod 503, pressure block 504, positioning rod 505, coil spring 507, and limiting ring 509.

[0028] In practical implementation: such as Figure 1 As shown, in one embodiment, a laminated wood includes: laminated wood 300, the bottom of which contacts the top of one of the pressure plates 200.

[0029] Working principle: The plunger 502 is slid into the fixing block 501 and abuts against one end of the bolt 400. The damping rod 503 is pushed down and locked in the plunger 502, pulling one side of the retainer 506 to deform. The elastic force of the coil spring 507 pushes the pressure block 504 to rotate, so that one side of the pressure block 504 can smoothly pass over one side of the retainer 506 and abut against the other side of the retainer 506, loosening the restriction on the retainer 506. The high elasticity of the retainer 506 causes it to reset, so that one side of the retainer 506 abuts against the other side of the pressure block 504, and the bottom of the pressure block 504 abuts against the top of the damping rod 503. The positioning rod 505 is pushed down and slides into the damping rod 503 and the fixing block 501, so that the plunger 502 is locked in the fixing block 501, and the pressure plate 200 is stably installed on the hot press frame 100.

[0030] It should be noted that the hot press frame 100, pressure plate 200, laminated wood 300, bolt 400, ball bearing 508, and connecting rope 510 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the hot press frame 100 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
