It should be noted that the present invention is a baking room for acrylic production, a closed space is defined by a bottom plate 1, a back plate 2, a first protection plate 41, a second protection plate 71, a top plate 6, a front plate 4 and a sealing door 91 to form a baking room, air in the baking room is extracted by a circulating air feeder 7 through a second conveying pipe 11, an air outlet pipe 12 and an air outlet mechanism 15 in sequence to form an air source, the air source is conveyed to a heating mechanism 9 from an air outlet of the circulating air feeder 7 to be heated, and then conveyed to the inside of the baking room through an air inlet pipe 10 and an air inlet mechanism 3, the used air is sucked into the air outlet pipe 12 by the circulating air feeder 7 to become the air source again, and the circulating heating is performed to form an internal heating circulating system, so as to increase the heating speed and to make the acrylic plate heated uniformly, and the contact area between a heating pipe group 23 and the air source is increased by arranging two vertical heating pipe groups 23, the heating speed of the air source is further improved, the production and processing efficiency of the acrylic plate is improved, the wind direction of hot air is adjusted by arranging the wind inlet mechanism 3, when the air inlet mechanism is used, the temperature in the drying room is detected by the temperature detector 14, when the temperature in the drying room does not reach a set value, the wind guide blades 43 are kept parallel to the bottom plate 1, the maximum air outlet quantity is ensured, the temperature in the drying room is rapidly improved, when the temperature rises to the set value, the control end 13 automatically starts the first servo motor 51, the output end of the first servo motor 51 drives the driving gear 52 to rotate, the driving gear 52 drives the driven gear 62 at the lowest side to rotate, the driven gear 62 at the lowest side drives other driven gears 62 which are in meshed connection with the driven gear 62 to rotate, further all the driven gears 62 synchronously rotate, the driven gear 62 drives the wind guide blades 43 to rotate by the rotating shaft 61, and the output end of the first servo motor 51 drives the wind guide blades 43 to rotate downwards, the output end of the first servo motor 51 rotates reversely, the air guide vane 43 rotates upwards, through programming control of output quantities such as rotating speed, rotating direction and the like of the first servo motor 51, the function of 'sweeping wind up and down' realized by the air guide vane 43 is realized, the acrylic plate in the drying room is uniformly heated, the integral heating quality of the acrylic plate is improved, the vertical opening and closing of the sealing door 91 are realized by arranging the sealing door mechanism 5, the contact area between the sealing door 91 and hot air in the drying room when the sealing door 91 is opened and closed is reduced, the temperature value swing amplitude in the drying room is reduced, the influence of the opening and closing of the sealing door 91 on the heating quality of the acrylic plate is reduced, when in use, the second servo motor 95 is started through the control end 13, the output end of the second servo motor 95 drives the positive and negative screw rod 93 to rotate, the positive and negative screw rod 93 drives the two driving blocks 92 to synchronously and relatively move, and the two driving blocks 92 respectively drive the two sealing doors 91 to synchronously and relatively move, both the corotation of second servo motor 95 output, two sealing door 91 are close to each other and realize closing the door, the reversal of second servo motor 95 output, two sealing door 91 keep away from each other and realize opening the door, set up first filtration hole 73 through setting up on first baffle 72, set up second filtration hole 75 on second baffle 74, filter great dust granule, debris etc. through first filtration hole 73 and second filtration hole 75, dust granule quantity among the hot air circulating system has been reduced under the internal heat circulation prerequisite that does not influence the baking house, the quality of ya keli board is improved.
