Technical Field

[0001] The utility model relates to the technical field of flame retardant board production equipment, and more specifically, to a flame retardant board cooling device. Background Art

[0002] Flame retardant board, also known as flame-retardant board, is a kind of man-made board with flame retardant properties, which is made by adding flame retardants during the production process of the board. As we all know, under high temperature and high pressure environment, the adhesive inside the board will be fused with each other by heat, so that a strong connection structure is formed inside the board, but this connection structure needs a certain amount of time to stabilize and solidify. If the board is directly machined or transported under high temperature, the unstable connection inside the board will be damaged, thus affecting the quality of the board after pressing.

[0003] In actual production, the newly pressed board is sent to the cooling equipment for cooling to stabilize the internal connection structure of the board. The current wood board cooling equipment generally uses gas cooling, for example, by spraying gas onto the surface of the flame retardant board to take away the heat from the surface of the flame retardant board, so that the temperature of the flame retardant board gradually decreases. Gas cooling has the advantage of avoiding pollution, but the cooling effect is relatively unsatisfactory and the cooling speed is slow. Utility Model Content

Figure 2-Figure 3As shown, the water-cooled conveying roller and the water-cooled guide roller include a roller body 19 and a hollow shaft body 18 located at both ends of the roller body 19. The hollow shaft bodies 18 at both ends are used to be rotatably connected to the conveying frame 1, and cooling water inlets 20 and cooling water outlets 21 are respectively provided at the outer ends of the two hollow shaft bodies 18. The cooling water inlet 20 and the cooling water outlet 21 are respectively connected to the water supply pipe and the water outlet pipe through a rotating joint. The interior of the roller body 19 is a hollow structure, including a coaxially arranged outer roller 22, an inner roller 23, and a plurality of partitions 24 supported and connected between the inner roller 23 and the outer roller 22. The two ends of the inner roller 23 are blocked and spaced apart from the two ends of the outer roller, so that an end gap 25 is provided between the end of the inner roller 23 and the end of the outer roller 22; the plurality of partitions 24 are evenly distributed in the annular space between the outer roller 22 and the inner roller 23 and divide the annular space into a plurality of branch channels 26, thereby, the two end gaps 25 and the plurality of branch channels 26 constitute a cooling channel inside the roller body 19 for cooling water to pass through, and the above-mentioned branch channels can better ensure that the water flows evenly in the rotating roller body 19, thereby improving the heat exchange effect.

[0019] A sprocket 7 is connected to the outer side of the hollow shaft at one end of the water-cooled conveying roller 4. All sprockets 7 are connected through a surrounding chain 6, including a driving sprocket and multiple driven sprockets. The driving component 3 is arranged at the driving sprocket, including a driving motor and a reducer. The output end of the reducer is connected to a driving gear. The outer side of the hollow shaft of the water-cooled conveying roller 4 provided with the driving sprocket is provided with a driven gear meshing with the driving gear, which then drives the driving sprocket to rotate. The driving sprocket drives other driven sprockets and the corresponding water-cooled conveying roller 4 to rotate through the chain 6 to realize the conveying action of the flame-retardant board. A discharging section 15 that tilts downward from front to back is provided at the rear of the conveying frame 1. A blocking plate 16 is provided at the rear end of the discharging end 15 to block the cooled flame-retardant board. At the same time, a flexible buffer pad is provided on the front side of the blocking plate to prevent the flame-retardant board from being damaged by collision.

[0020] The air cooling mechanism includes an air cooling cover 8, which is arranged outside the middle section of the roller conveying mechanism, and a plurality of air nozzles 9 are installed on the inner side of the top of the air cooling cover 8.

An air pump 14 for extracting gas from the air cooling cover is provided on the exhaust pipe 13.

[0021] A plurality of water-cooled guide rollers 5 are installed in a side-by-side manner in front of the feed port 27 on the conveyor frame, and cooling water is circulated through the water supply pipe and the water outlet pipe. The water-cooled guide rollers 5 are arranged above the water-cooled conveying rollers 4. Different from the active conveying movement of the water-cooled conveying rollers, when the flame-retardant board is conveyed backward by the water-cooled conveying rollers 4, it contacts and drives the water-cooled guide rollers 5 to rotate together. The water-cooled guide rollers 5 fully contact and exchange heat with the flame-retardant board during the passive rotation process, thereby achieving the purpose of cooling the flame-retardant board.

[0022] The use process of the flame retardant plate cooling device of the utility model is as follows: the flame retardant plate is placed in the front part of the roller conveying mechanism, and the flame retardant plate is conveyed backwards under the action of the water-cooled conveying roller, and at the same time, it contacts and exchanges heat with the water-cooled guide roller 5 and the water-cooled conveying roller 4, and enters the air-cooled cover 8 in the middle, and the heat on the surface of the flame retardant plate is taken away by the cold wind. After being heated to hot air, the cold wind moves downward through the gap between the water-cooled conveying rollers, is gathered by the wind gathering section, and is quickly discharged through the exhaust pipe 13 under the action of the vacuum pump; after being sent out of the air-cooled cover 8, the flame retardant plate continues to exchange heat with the water-cooled conveying roller 4 through water cooling, and continues to cool down until it is finally sent to the discharge section 15. In the above process, the flame retardant plate is cleverly cooled by the two cooling methods of water cooling and air cooling, and it contacts and exchanges heat with the water-cooled guide roller 5 and the water-cooled conveying roller 4 continuously during the conveying process, so as to achieve the effect of accelerating the cooling speed and rapid cooling.
