[0002] The hot pressing process of polyurethane insulation board is a process in which the polymer compounds in the raw materials undergo polymerization reaction under a certain temperature and pressure after the raw materials are pretreated to form a polyurethane insulation board with a certain shape and performance. The polyurethane insulation board has excellent thermal insulation performance, moisture-proof and waterproof performance, fire retardant performance, high temperature resistance, strong deformation resistance, not easy to crack, stable and safe surface, etc.

[0003] If the heat is not dissipated in time after the hot pressing process, the polyurethane insulation board may have various adverse effects. First, the thermal insulation performance may decrease, because the hot pressing process will cause the polyurethane foam to be compressed, thereby reducing its thermal insulation performance. Secondly, the insulation board may be deformed or cracked, which is caused by the thermal expansion and contraction effect. Finally, the fire resistance of the polyurethane foam may also be affected, because the fire resistance may be reduced if the heat is not dissipated in time after hot pressing.

When the insulation board is dissipating heat, the hydraulic press makes the first pressure plate 3 and the second pressure plate 6 keep clamping the insulation board, which will increase the strength of the insulation board, make it more compact, and prevent the surface of the insulation board from being uneven after thermal expansion and contraction.

[0040] The first heat dissipation tube 10 includes a straight tube 15 and a special-shaped tube 16; a group of straight tubes 15 are fixedly connected to the top of the first pressure plate 3, and the adjacent straight tubes 15 are connected by special-shaped tubes 16; the special-shaped tube 16 includes a pair of L-shaped tubes 161 and a U-shaped tube 162; the pair of L-shaped tubes 161 are fixedly connected by the U-shaped tube 162; the end of the L-shaped tube 161 away from the U-shaped tube 162 is connected to the straight tube 15; the second heat dissipation tube 12 has the same structure as the first heat dissipation tube 10; the side wall of the water tank 9 is fixedly connected to the first U-shaped heat conduction tube 17; the outer wall of the first U-shaped heat conduction tube 17 is in contact with the inner wall of the special-shaped tube 16 on the first heat dissipation tube 10; A pair of second hoses 18 are fixedly connected to the side wall; one end of the pair of second hoses 18 is fixedly connected to the two ends of the second U-shaped heat-conducting pipe 19 respectively; the outer wall of the second U-shaped heat-conducting pipe 19 is in contact with the inner wall of the special-shaped pipe 16 on the second heat-dissipating pipe 12.

The hot melt adhesive will enter the storage box 33 for collection, and the storage box 33 will be placed on the bottom of the magnetic block 32 of the frame 2 through magnetic attraction. The strength of the magnetic attraction can prevent the storage box 33 from falling off the magnetic block 32 of the frame 2 when filled with hot melt adhesive, so that the staff can easily install and remove the storage box 33 from the bottom of the frame 2, avoiding the excess hot melt adhesive from remaining and solidifying on both sides of the insulation board after the insulation board dissipates heat on the frame 2, thereby having the effect of cleaning the insulation board.

[0053] Working principle: the hot pressing assembly 1 is a prior art, and its function is to hot press the insulation board into shape. No further description is given. The formed insulation board will be transported to the frame 2 at the discharge port of the hot pressing assembly 1. At this time, the insulation board will be between the first pressing plate 3 and the second pressing plate 6. When the hydraulic cylinder 5 is started, the second pressing plate 6 on the hydraulic cylinder 5 will drive the insulation board to move upward, so that the first pressing plate 3 and the second pressing plate 6 clamp the insulation board. Then, the water pump 14 is started to allow the water in the water tank 9 to enter the first heat dissipation pipe 10 on the first pressing plate 3 through the connecting pipe 11, and then return to the water tank 9 from the connecting pipe 11 at the other end of the first heat dissipation pipe 10, and the water enters the second heat dissipation pipe 12 from the first hose 13, and enters the second heat dissipation pipe 12 from the second heat dissipation pipe 12. The first hose 13 at the other end of the heat pipe 12 returns to the water tank 9, which can effectively transfer the heat of the insulation board to the first pressing plate 3 and the second pressing plate 6, and then take the heat away through the first radiating pipe 10 and the second radiating pipe 12, so as to achieve the effect of heat dissipation. When the insulation board dissipates heat, the hydraulic press makes the first pressing plate 3 and the second pressing plate 6 keep clamping the insulation board, which will increase the strength of the insulation board and make it more compact, and prevent the insulation board from having uneven surfaces after thermal expansion and contraction. The water in the water tank 9 is circulated from the first U-shaped heat conducting pipe 17 by the water pump 14. When the water in the first radiating pipe 10 enters the special-shaped pipe 16 from the straight pipe 15, the shape of the special-shaped pipe 16 increases the heat dissipation area, so that the first The contact area between the heat dissipation pipe 10 and the first U-shaped heat-conducting pipe 17 increases, so that the heat transfer efficiency of the first U-shaped heat-conducting pipe 17 to the first heat dissipation pipe 10 is improved, and the first heat dissipation pipe 10 is cooled. The blower 22 is a prior art, and its function is to accurately deliver a certain amount of air. No further description is given. After the blower 22 inputs the air volume into the air outlet pipe 23, the wind in the air outlet pipe 23 will enter the ventilation pipe 201, and the wind in the ventilation pipe 201 will enter the ventilation slot 20 from the vent 21. After the first pressing plate 3 and the second pressing plate 6 clamp the insulation plate, the ventilation slot 20 can increase the air circulation between the first pressing plate 3 and the second pressing plate 6 and the insulation plate, and quickly dissipate the heat on the insulation plate. The amount of heat can be reduced, thereby better reducing the temperature of the heat preservation board and improving the cooling efficiency. The wind in the blower 22 enters the L-shaped air duct 25 from the air outlet 23, and then enters the heat dissipation air duct 26 from the L-shaped air duct 25. The wind will blow to the heat dissipation fins 29 at the blowing port 28 of the heat dissipation air duct 26. The heat dissipation fins 29 can increase the heat dissipation area of ​​the side wall of the water tank 9, so that better heat can be dissipated through the fins. When the wind is output to the heat dissipation fins 29, the air flow around the heat dissipation fins 29 will be accelerated, and the heat dissipation efficiency of the heat dissipation fins 29 will be improved, thereby reducing the temperature of the water tank 9. When the heat preservation board is transferred from the discharge port to the frame 2 through the hot pressing component 1, the scraper 31 on the frame 2 will contact the side wall of the heat preservation board.When the insulation board is hot-pressed, the excess hot-melt adhesive squeezed out on both sides of the insulation board is scraped off, and the hot-melt adhesive will enter the storage box 33 for collection. The storage box 33 is placed on the bottom of the frame 2 by magnetic attraction, so that the staff can easily install and remove the storage box 33 from the bottom of the frame 2, avoiding that the excess hot-melt adhesive will remain and solidify on both sides of the insulation board after the insulation board dissipates heat on the frame 2, thereby playing the effect of cleaning the insulation board, and the servo motor 35 drives the threaded rod 36 to rotate , so that the rotation of the threaded rod 36 drives the L-shaped block 37 to slide in the L-shaped groove 34, and then the L-shaped block 37 drives the cleaning plate 39 on the multi-section telescopic rod 38 to move. When the cleaning plate 39 moves, it will be limited by the slider 40 in the slide groove 41. After the scraper 31 scrapes off the excess hot melt adhesive on the side wall of the insulation board, the servo motor 35 is started to move the cleaning plate 39 downward, so that the cleaning plate 39 sweeps the hot melt adhesive on the scraper 31 into the storage box 33, and the surface of the scraper 31 is cleaned. ;
