[0034] As Figures 1-6 shown, this embodiment provides a drying device for piano boards, including: a heat-insulated room, two lifting mechanisms, a transverse movement mechanism, a plurality of material trays 4, a material transfer mechanism 5, and a heating device disposed in the heat-insulated room;

[0035] The two lifting mechanisms are arranged at intervals in the left - right direction. Each lifting mechanism has a plurality of material storage areas arranged vertically, and each material storage area can accommodate one sheet. The two lifting mechanisms operate synchronously and in opposite driving directions. Each lifting mechanism includes two sets of first belt transmission components 21 and two first driving devices 22. The two sets of first belt transmission components 21 are arranged opposite to each other in the front - rear direction and are used to support the two ends of the sheet. Each set of first belt transmission components 21 is correspondingly connected to one first driving device 22;

[0036] The transverse movement mechanism is used to drive the sheet to transfer between the two first belt transmission components 21. The transverse movement mechanism includes two flat - push devices 31 and a second driving device 32. The two flat - push devices 31 are respectively located on the upper and lower sides of the lifting mechanism. The second driving device 32 is drivingly connected to the two flat - push devices 31. The two flat - push devices 31 operate synchronously and in opposite driving directions;

[0037] Among them, the material storage area at the bottom of the lifting mechanism that drives upward is set as the inlet - outlet position. The heat - preservation room is provided with an inlet and an outlet, and the outlet and the inlet are respectively opened on the opposite sides of the inlet - outlet position. The material transfer mechanism 5 is arranged below the inlet - outlet position, and the material transfer mechanism 5 is used to drive the sheet located at the inlet - outlet position away from the heat - preservation room;

[0038] Each tray 4 is arranged in one of the material storage areas. The tray 4 moves within the circulating conveyor line. The tray 4 is used for placing the sheet to prevent the direct contact between the lifting mechanism and the transverse movement mechanism and the sheet, so as to avoid damaging the sheet during the conveying process;

[0039] The heating device is used to generate heat to create a high - temperature environment in the heat - preservation room to dry the sheet.

[0040] The lifting mechanism uses the belt - driving method, which can achieve the effect of continuous driving and there is no situation of reset and then driving. In this way, combined with the cooperation of the two flat - push devices 31, a circulating conveyor line is formed to drive the sheet to circulate and convey within the heat - preservation room. According to the time required for drying the sheet, set the running speed of the circulating conveyor line so that the sheet enters the inlet - outlet position from the inlet. After passing through one round of the circulating conveyor line and returning to the inlet - outlet position again, it just reaches the required drying time and then leaves from the outlet to achieve drying. In this way, during the processing of sheet coating and drying, the continuity of the process can be ensured, and there is no waste caused by the waiting time of the sheet during drying and the idleness of manpower, thus improving production efficiency.

[0041] (The direction in which the outlet and the inlet are opposite is the front - rear direction, and the driving direction of the transverse movement mechanism is the left - right direction.)

[0042] As a preferred solution, the heat preservation room includes a structural frame 11 and heat insulation boards (not shown in the figure). The lifting mechanism, the transverse movement mechanism, and the heating device are located inside the structural frame 11. The heat insulation boards (not shown in the figure) cover the outer side surface of the structural frame 11, separating the inside and outside of the structural frame 11 to form a heat preservation space, so as to achieve the effect of drying and heat preservation.

[0043] As Figures 1-6 shown, as a preferred solution, the material tray 4 includes a frame body 41 and a plurality of first rollers 42. The frame body 41 is rectangular, and the plurality of first rollers 42 are arranged at intervals in the front-back direction inside the frame body 41. The first rollers 42 are non-powered rollers.

[0044] As Figures 1-3 shown, as a preferred solution, each group of the first belt transmission assemblies 21 has two first belt transmission assemblies 21, and the two first belt transmission assemblies 21 are arranged at intervals in the left-right direction; a plurality of support blocks 213 are arranged at intervals on each first belt transmission assembly 21, and the support blocks 213 of the two groups of first belt transmission assemblies 21 jointly support the material tray 4, and a storage area is formed between the upper and lower support blocks 213.

[0045] As Figures 2-3 shown, further, the first belt transmission assembly 21 includes a first belt 211 and two first transmission wheels 212. The two first transmission wheels 212 are arranged at intervals up and down on the structural frame 11. One of the first transmission wheels 212 is drivingly connected to the first driving device 22. The first belt 211 is sleeved on the two first transmission wheels 212, and the support blocks 213 are arranged at intervals outside the first belt 211.

[0046] As Figure 1 shown, further, the first driving device 22 includes a first motor 221 and a first synchronizing rod 222. The first motor 221 is drivingly connected to the first synchronizing rod 222, and the first synchronizing rod 222 is drivingly connected to the corresponding two first transmission wheels 212 located above or below, so as to realize the synchronous operation of the two first belt transmission assemblies 21 in the same group.

[0047] As Figure 1 and 2, as shown in FIGS. 4 and 5, as a preferred solution, each of the horizontal pushing devices 31 includes a support rail 311 and a second belt drive assembly 312. The support rail 311 is movably arranged on the structural frame 11. The support rail 311 forms a track connecting the two first belt drive assemblies 21, providing support for the lateral movement of the tray 4. The second belt drive assembly 312 is provided with a push block 3123, and the tray 4 is pushed to move laterally through the push block 3123. Specifically, the second belt drive assembly 312 located above drives the tray 4 located at the top to move laterally through the push block 3123 below it, and the second belt drive assembly 312 located below pushes the tray 4 located at the bottom to move laterally through the push block 3123 above it. Based on the principle that the driving directions on both sides of the belt drive assembly are opposite, the driving directions of the two second belt drive assemblies 312 are opposite.

[0048] As Figure 5 shown, further, there are two support rails 311 for each of the horizontal pushing devices 31. The two support rails 311 are arranged on the front and rear sides of the lifting mechanism to support the front and rear ends of the tray 4. Specifically, the support rail 311 includes a support bar 3111 and a third motor 3112. The support bar 3111 extends in the left-right direction. The support bar 3111 is rotatably arranged on the structural frame 11. The support bar 3111 has a support surface 3101 for supporting the tray 4. The third motor 3112 is drivingly connected to the support bar 3111 to drive the support bar 3111 to swing towards the first belt drive assembly 21, so that the support surface 3101 changes between a horizontal state and a vertical state.

[0049] Specifically, when the support surface 3101 is in the horizontal state, the support surface 3101 is within the vertical range of the first belt drive assembly 21 and supports the tray 4. When the support surface 3101 is in the vertical state, the support surface 3101 leaves the vertical range of the first belt drive assembly 21 to avoid interfering with the operation of the first belt drive assembly 21. When the support surface 3101 is in the horizontal state, its horizontal height is slightly higher than the horizontal height of the top surface of the corresponding support block 213. The support surface 3101 changes to the horizontal state in an upward swinging manner and changes to the vertical state in a downward swinging manner, thus realizing the alternating conversion of the support for the tray 4.

[0050] As Figure 1 , 2, as shown in FIGS. 4, further, the second driving device 32 further includes a second motor 321 and a synchronous belt assembly 322. The second motor 321 is drivingly connected to one of the second belt transmission assemblies 312, and the synchronous belt assembly 322 is drivingly connected to the two second belt transmission assemblies 312. The synchronous belt assembly 322 enables the two second belt transmission assemblies 312 to operate synchronously.

[0051] As Figure 1 , 2 shown, preferably, each of the second belt transmission assemblies 312 of the flat pushing device 31 is provided with two. The second motor 321 is connected to the two second belt transmission assemblies 312 on the same side through a second synchronous rod 323, so as to provide multiple force application points for the tray 4 and make the lateral movement of the tray 4 more stable (the second synchronous rod 323 is a conventional belt transmission structure and will not be elaborated here).

[0052] As Figure 1 , 2 , as shown in FIGS. 4, further, the second belt transmission assembly 312 includes a second belt 3121 and two second transmission wheels 3122. The two second transmission wheels 3122 are arranged at intervals left and right on the structural frame 11. The second belt 3121 is sleeved on the two second transmission wheels 3122. The transmission distance on one side of the second belt 3121 covers the left and right sides of the two first belt transmission assemblies 21. Therefore, the push block 3123 is arranged on the second belt 3121. The synchronous belt assembly 322 is drivingly connected to the corresponding upper and lower two second transmission wheels 3122 on the same side;

[0053] As Figure 1 , 2 , as shown in FIGS. 4, further, the synchronous belt assembly 322 includes a third belt, two third transmission wheels, and two third synchronous rods. The two third transmission wheels are respectively coaxially arranged with the corresponding upper and lower two second transmission wheels 3122. The third synchronous rod is rotatably installed on the structural frame 11, and each third synchronous rod is drivingly connected to the corresponding second transmission wheel 3122 and third transmission wheel. The third belt is sleeved on the two third transmission wheels.

[0054] As Figure 1 , 4As shown in the figure, further, the transverse movement mechanism further includes a plurality of trigger feedback devices 33, which are arranged on the structural frame 11. Each trigger feedback device 33 is located at the corresponding end of the corresponding support rail 311. When the tray 4 touches the trigger feedback device 33 during the lateral movement, it indicates that the tray 4 has laterally moved to the specified position. Then, the second driving device 32 stops operating, and the support bar 3111 resets. Such a setting provides an additional layer of insurance to prevent the tray 4 from moving excessively and colliding with the structural frame 11.

[0055] As Figure 6 shown in the figure, as a preferred solution, the material transfer mechanism 5 includes a lifting cylinder 51, a connecting frame 52, and a plurality of second rollers 53. The lifting cylinder 51 is arranged on the structural frame 11. The connecting frame 52 is arranged at the output end of the lifting cylinder 51. The plurality of second rollers 53 are arranged at intervals at the top of the connecting frame 52. From a top view, each second roller 53 is located between two adjacent first rollers 42. The second roller 53 is a self-powered roller.

[0056] Specifically, when the lifting cylinder 51 drives the connecting frame 52 to rise, the second roller 53 passes through between the two first rollers 42 and rises to support the board. The second roller 53 rotates to convey the board towards the outlet, enabling the board to leave the insulation room. A new board can enter from the inlet simultaneously. Then, the lifting cylinder 51 drives the connecting frame 52 to descend, and the new board is placed on the tray 4 for subsequent cyclic conveyance.

[0057] As Figure 1 shown in the figure, preferably, the first motor 221 is arranged on the structural frame 11. The first synchronizing rod 222 is in transmission connection with the corresponding two first transmission wheels 212 located above. The first motor 221 is drivingly connected to the first synchronizing rod 222 through a fourth belt transmission assembly 223 (the fourth belt transmission assembly 223 is a conventional belt transmission structure and will not be elaborated further here). The second motor 321 is arranged on the structural frame 11. The second motor 321 is drivingly connected to the second belt transmission assembly 312 located below. The first motor 221 and the second motor 321 are staggered in space to meet the space requirements of the insulation room and facilitate installation and maintenance.

[0058] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
