DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example 1 See also Figure 1-8 The present embodiment provides a drying device for the production of artificial boards, including a conveyor 1 for conveying artificial boards and a drying component 2 arranged on the conveyor 1. The processed artificial boards are conveyed by the conveyor 1. When the conveyor 1 conveys the artificial boards to the bottom of the drying component 2, the conveyor 1 stops working, and then the artificial boards are dried by the drying component 2.

[0019] The drying assembly 2 includes two symmetrical vertical plates 21, which are fixed on both sides of the conveyor 1. A horizontal plate 22 is provided on the top of the two vertical plates 21, and an electric hydraulic push rod 23 is provided at the center of the surface of the horizontal plate 22. A support plate 24 that can move up and down is provided below the horizontal plate 22. The output end of the electric hydraulic push rod 23 passes through the horizontal plate 22, and one end of the electric hydraulic push rod 23 located below the horizontal plate 22 is fixedly connected to the support plate 24; a drying plate 25 for drying the artificial board is provided below the support plate 24, and the drying plate 25 is located above the conveyor 1. The four corners of the surface of the support plate 24 are provided with an air intake structure 29, and the air intake structure 29 is used to convey the drying plate 25. High-pressure hot air, when the conveyor 1 conveys the artificial board to be dried to the bottom of the drying component 2, the conveyor 1 stops working, and then the electric hydraulic push rod 23 pushes the support plate 24 and the drying plate 25 to move downward, so that the drying plate 25 is close to the artificial board, and then the high-pressure hot air is conveyed to the drying plate 25 through the air intake structure 29, and then the drying plate 25 blows out the high-pressure hot air evenly from the air outlet 253 below, forming a flowing hot air layer under the drying plate 25, and the artificial board is dried by the flowing hot air layer, so as to avoid local overheating of the artificial board and prevent cracks from appearing on the surface of the artificial board during the drying process, thereby improving the processing quality of the artificial board.

[0020] Among them, the support plate 24 is provided with a guide rod 26 that passes through the cross plate 22, and the cross plate 22 is provided with a guide sleeve 27 at a position corresponding to the guide rod 26. The guide rod 26 passes through the central axis of the guide sleeve 27, and the guide rod 26 and the guide sleeve 27 are slidably connected. The support plate 24 is slidably installed under the cross plate 22 through the cooperation of the guide rod 26 and the guide sleeve 27. When the electric hydraulic push rod 23 is working, it can push the support plate 24 to move up and down in the vertical direction under the cross plate 22 to prevent the support plate 24 from tilting during the up and down movement.

[0021] Among them, the drying plate 25 includes a plate body 251 arranged below the supporting plate 24, a hollow cavity 252 is arranged inside the plate body 251, and air outlets 253 penetrating the hollow cavity 252 are evenly opened on the lower surface of the plate body 251. The air intake structure 29 is used to transport high-pressure hot air to the inside of the hollow cavity 252. When the drying plate 25 is needed to dry the artificial board, hot air is generated by an external hot air blower, and then the hot air blower transports the hot air to the air intake structure 29, and then the air intake structure 29 pressurizes the hot air to become high-pressure hot air, and transports the high-pressure hot air into the hollow cavity 252, and then the hot air in the hollow cavity 252 is blown out through the air outlet 253, forming a flowing hot air layer under the drying plate 25, and the artificial board is dried by the flowing hot air layer, so as to avoid local overheating of the artificial board and prevent cracks from appearing on the surface of the artificial board during the drying process, thereby improving the processing quality of the artificial board.

[0022] Among them, the air intake structure 29 includes an air compressor 291 fixedly installed at the corners of the upper surface of the support plate 24, and an air intake cylinder 292 is provided at the corners of the lower surface of the support plate 24. The bottom of the air intake cylinder 292 extends into the hollow cavity 252, and the output end of the air compressor 291 is connected with the top of the air intake cylinder 292; the air compressor 291 compresses the hot air and transports it to the inside of the hollow cavity 252 through the air intake cylinder 292. When the drying board 25 is required to dry the artificial board, hot air is generated by an external hot air blower, and then the hot air blower transports the hot air to the air compressor 291, and the hot air is pressurized into high-pressure hot air by the air compressor 291, and then the high-pressure hot air is transported to the hollow cavity 252 through the air intake cylinder 292.

[0023] Example 2 See also Figure 1-8 On the basis of Example 1, this embodiment further includes: a telescopic spring 293 is sleeved on one side of the surface of the air inlet cylinder 292 located between the support plate 24 and the plate body 251, one end of the telescopic spring 293 is fixedly connected to the lower surface of the support plate 24, and the other end of the telescopic spring 293 is fixedly connected to the upper surface of the plate body 251; the air inlet cylinder 292 is slidably connected to the plate body 251, and when the electric hydraulic push rod 23 pushes the support plate 24 and the drying plate 25 to move downward, the drying plate 25 will contact the artificial board to be dried. In order to avoid a rigid collision between the drying plate 25 and the artificial board, a telescopic spring 293 is sleeved on one side of the surface of the air inlet cylinder 292 located between the support plate 24 and the plate body 251. When the plate body 251 contacts the artificial board, the artificial board will apply an upward force to the plate body 251, and at the same time, the plate body 251 will generate a pressure on the telescopic spring 293, so that the telescopic spring 293 shrinks along the air inlet cylinder 292, thereby playing a buffering role and avoiding a rigid collision between the drying plate 25 and the artificial board.

[0024] At the same time, in the process of the plate body 251 drying the artificial board, in order to improve the drying effect, the lower surface of the plate body 251 can be in contact with the surface of the artificial board, and then hot air is generated by an external hot air blower, and then the hot air is transported to the air intake structure 29, and then the air intake structure 29 pressurizes the hot air into high-pressure hot air, and transports the high-pressure hot air to the hollow cavity 252, and then the hot air in the hollow cavity 252 is blown out through the air outlet 253, and the hot air is directly blown onto the artificial board to improve the drying efficiency; however, when the plate body 251 is in direct contact with the surface of the artificial board, the hot air blown out from the air outlet 253 cannot spread, and the artificial board will block the air outlet 253, resulting in the inability to further carry out the air outlet drying process; therefore, the telescopic spring 293 on the air intake cylinder 292 plays a role, and when the plate body 251 is in contact with the artificial board, air is discharged through the air outlet 253 on the lower surface of the plate body 251 to dry the artificial board. After the hot air is blown out from the air outlet, wind pressure is generated, and a reaction force on the plate body 251 is also formed. Under the action of the wind pressure, the plate body 251 moves upward along the air inlet pipe 292 for a certain distance. Due to the existence of the telescopic spring 293, the distance that the plate body 251 moves upward under the reaction force of the wind pressure is limited. Therefore, a gap is formed between the plate body 251 and the artificial board, which is convenient for the hot air blown out from the air outlet 253 to circulate, ensuring that the air outlet 253 on the lower surface of the plate body 251 can blow out the hot air normally. At the same time, under the action of the telescopic spring 293, even if the plate body 251 moves upward under the action of the wind pressure, the elastic force of the telescopic spring 293 will push the plate body 251 to move downward, ensuring that there is a gap for the circulation of hot air between the lower surface of the plate body 251 and the artificial board from time to time, and the lower surface of the plate body 251 contacts the surface of the artificial board from time to time, preventing the hot air from flowing too fast, thereby saving resources.

[0025] Among them, an air outlet disc 294 is provided at one end of the air inlet cylinder 292 located inside the hollow cavity 252, and a hollow inner cavity is provided inside the air outlet disc 294. Air outlet holes 295 that penetrate the inner cavity are evenly opened along the circumferential direction on the surface of the air outlet disc 294. In order to prevent the air inlet cylinder 292 from separating from the plate body 251, an air outlet disc 294 is assembled at the end of the air outlet cylinder 292. At the same time, in order to facilitate the air outlet disc 294 to transport hot air to the inside of the hollow cavity 252, a circle of air outlet holes 295 for ventilation are arranged around the surface of the air outlet disc 294.

[0026] The output end of the air compressor 291 is connected to the inner cavity through the air inlet cylinder 292.

[0027] It also includes a hot air blower, the output end of the hot air blower is connected to the input end of the air compressor 291 by a pipeline, the hot air blower can be externally connected and placed independently next to the conveyor 1, hot air is generated by the hot air blower, and then the hot air is transported to the air compressor 291, the hot air is pressurized by the air compressor 291 to form high-pressure hot air, and then the high-pressure hot air is transported to the hollow cavity 252 through the air inlet pipe 292, and then the high-pressure hot air is blown out through the air outlet 253 on the lower surface of the plate body 251 to dry the artificial board.

[0028] Among them, the conveyor 1 includes a support frame 12, two symmetrical support legs 11 are provided at the bottom of both ends of the support frame 12, two groups of symmetrical conveying chains 13 are installed on the support frame 12 for transmission, and a servo motor 14 for driving the conveying chain 13 to convey is provided at one end of the support frame 12. The two conveying chains 13 can be driven by the servo motor 14 to convey, and the two ends of the lower surface of the artificial board are respectively in contact with the two symmetrical conveying chains 13, and the artificial board is conveyed forward by the conveying chain 13.

[0029] Among them, both ends of the support frame 12 are rotatably installed with rotating shafts, and both ends of each rotating shaft are provided with gears that cooperate with the transmission chain 13. A driven wheel is sleeved on one of the rotating shafts, and the output end of the servo motor 14 is provided with a driving wheel that meshes with the driven wheel. The driving wheel is driven to rotate by the servo motor 14, and the rotating shaft is driven to rotate through the cooperation of the driving wheel and the driven wheel, thereby driving the gear on the rotating shaft to rotate, thereby achieving the purpose of driving the two transmission chains 13 to transmit.

[0030] Working principle: The processed artificial board is transported by the conveyor 1. When the conveyor 1 transports the artificial board to the bottom of the drying component 2, the conveyor 1 stops working, and then the support plate 24 and the drying plate 25 are pushed downward by the electric hydraulic push rod 23, so that the lower surface of the drying plate 25 contacts the surface of the artificial board, and then hot air is generated by the hot air blower, and then the hot air is transported to the air compressor 291, and the hot air is pressurized by the air compressor 291 to form high-pressure hot air, and then the high-pressure hot air is transported to the hollow cavity 252 through the air inlet pipe 292, and the air is discharged through the air outlet 253 on the lower surface of the plate body 251 to dry the artificial board. After the hot air is blown out at the air outlet, wind pressure is generated, and a reaction force on the plate body 251 is also formed. Under the action of the wind pressure , so that the plate body 251 moves a little distance upward along the air inlet pipe 292. Due to the existence of the telescopic spring 293, the distance that the plate body 251 moves upward under the reaction force of the wind pressure is limited. Therefore, a gap will be formed between the plate body 251 and the artificial board, which is convenient for the hot air blown out of the air outlet 253 to circulate, ensuring that the air outlet 253 on the lower surface of the plate body 251 can blow out hot air normally. At the same time, under the action of the telescopic spring 293, even if the plate body 251 moves upward under the action of the wind pressure, the elastic force of the telescopic spring 293 will push the plate body 251 to move downward, ensuring that there is sometimes a gap for hot air circulation between the lower surface of the plate body 251 and the artificial board, and sometimes the lower surface of the plate body 251 contacts the surface of the artificial board, preventing the hot air from flowing too fast and saving resources.
