Description

Technical Field

[0001] This utility model relates to the field of particleboard coating technology, specifically a hot pressing device for flexible coating of particleboard surface. Background Technology

[0002] Hot-pressing equipment for flexible lamination of particleboard surfaces is a core supporting equipment in the field of deep processing of engineered wood products. Its core function is to precisely control the temperature and pressure to tightly bond flexible lamination materials such as PVC, PET, non-woven fabric, and wood veneer to the surface of the particleboard substrate, achieving a firm bond between the lamination layer and the substrate. At the same time, it ensures that the particleboard surface is flat, flawless, and has clear texture, combining both decorative and protective properties. It is a key processing step to enhance the added value of particleboard products and expand their application scenarios.

[0003] The prior art discloses a hot-pressing and laminating device for foam boards, with announcement number CN217144895U. The device includes a box and a storage platform. The storage platform is located at the front of the box, a winding adjustment knob is located on the left side of the box, a placement tube is located at the upper end of the box, and a rotating tube is located on the inner side of the box. This invention improves the hot-pressing and laminating device for foam boards by adding a pressure plate at the upper end of the conveyor belt and a telescopic inner plate at the upper end of the pressure plate. The telescopic outer plate and the telescopic inner plate are connected by fastening bolts. When using the hot-pressing and laminating device for foam boards, the foam board is placed on the upper end of the conveyor belt, and then the position of the pressure plate is adjusted so that the pressure plate flattens the foam board conveyed below.

[0004] The aforementioned hot-pressing device for flexible film coating of particleboard, through the setting of the pressure plate, allows the foam board to be better coated when using the hot-pressing film coating device for foam board, thereby making the hot-pressing film coating device for foam board work better. However, the aforementioned hot-pressing rollers cannot move laterally, and when the thickness of the particleboard required for the pressure is greater than the roller diameter, incomplete film pressing is likely to occur, which needs to be improved.

[0009] Preferably, the magnetic limiting strip is slidably connected to one end of the magnetic suction plate, and the magnetic limiting strip is magnetically connected to the magnetic suction plate. The magnetic limiting strip and the magnetic suction plate are magnetically connected to each other. This avoids slippage when the magnetic limiting strip is pushed to move to the side of the particle plate, and also avoids slippage that affects the limiting fit during the limiting process.

[0010] Preferably, the side area of ​​the magnetic limiting strip is adapted to the internal area of ​​the connecting frame plate.

[0011] Preferably, the top of the connecting platform is provided with a rectangular slot, the width of the hydraulic cylinder is adapted to the width of the rectangular slot, and the hydraulic cylinder is slidably connected to the top of the connecting platform.

The two hot pressing treatments can ensure that the pressing is complete and there will be no omissions in the coating.

[0016] 2. This hot pressing device for flexible film coating on particleboard surface, by setting a limiting component, places the particleboard to be hot-pressed on top of the conveyor belt. During placement, one side of the particleboard needs to be close to one end of the conveyor belt before conveying. Before conveying, the position of the magnetic limiting strip on the other side needs to be adjusted so that the magnetic limiting strip on the other side can fit against the other end of the particleboard without clamping force, thus limiting the conveying and ensuring stable conveying, avoiding skewing that would affect the integrity of hot pressing, and reducing the possibility of omissions.

A heating wire 315 is fixedly connected to the right side of the fan housing 314. A ventilation slot is opened on the left side of the fan housing 314. A filter screen is installed inside the ventilation slot. After the hot pressing is completed during the transmission process, the fan inside the fan housing 314 can be started to generate airflow towards the particle plate. Before starting, the heating wire 315 can be turned on to heat the gas introduced into the fan housing 314, and then blown out through the ventilation slot to help dry the gas and further ensure the adhesion of the film. A rectangular slot is opened on the top of the connecting platform 301. The width of the hydraulic cylinder 302 is adapted to the width of the rectangular slot. The hydraulic cylinder 302 is slidably connected to the top of the connecting platform 301. A limit strip 305 is fixedly connected to the top of the connecting platform 301.

[0026] The limiting assembly 4 includes a connecting frame plate 401, a rectangular plate 402, a screw 403, a thumb sleeve 404, a magnetic limiting strip 405, and a magnetic suction plate 406. The connecting frame plate 401 is fixedly connected to the inner sides of the connecting platform 301 near the bottom. The rectangular plate 402 is fixedly connected to the front of the connecting platform 301. The rectangular plate 402 has a threaded groove inside.

[0027] In use, place the granule plate to be hot-pressed on top of the conveyor belt 5, with one side of the granule plate close to one end of the conveyor belt 5 so that one side of the granule plate can contact the magnetic limiting strip 405 on one side. Then, start the conveyor drive motor 6 to drive the inner conveyor roller 7 to rotate and transport the granule plate. Before transport, adjust the position of the other magnetic limiting strip 405 so that it fits snugly against the other end of the granule plate without clamping force, thus limiting the transport and ensuring stable transport, avoiding skewing that could affect the integrity of the hot pressing and reducing omissions. After being transported to the bottom of the hot pressing roller 310, the granule plate can be hot-pressed using the hot pressing roller 310. The position and width of the granule plate and surface coating can be adjusted according to the specific conditions. Adjust the left and right positions of the hot press roller 310 for comprehensive hot pressing. During adjustment, the hydraulic telescopic rod 304 can be activated to drive the hydraulic cylinder 302 to move laterally, thereby adjusting the lateral position of the hot press roller 310. Adjust the right side of the hot press roller 310 to align with the right side of the granule plate. Then, activate the hydraulic cylinder 302 to drive the connecting column 308 downward. Adjust according to the thickness of the granule plate to ensure that the bottom of the hot press roller 310 can contact the film on the top of the granule plate. Then, perform hot pressing during the transmission process. When the thickness of the granule plate is greater than the length of the hot press roller 310, the hydraulic telescopic rod 304 can be activated after transmission to drive the hydraulic cylinder 302 to move to the left. This time, align the left side of the hot press roller 310 with the left side of the granule plate. Two hot pressing processes can ensure comprehensive pressing and prevent any omissions in the film coating.
