[0040] See also Figure 1-2 , Figure 4 and Figure 7 A curing furnace, suitable for honeycomb panels, includes a curing furnace body 1, and also includes: a support shaft 2, which is rotatably arranged on the upper and lower inner walls of the curing furnace body 1 through bearings, and a driving member 3 connected to the support shaft 2 is arranged on the top of the curing furnace body 1. The driving member 3 in this application adopts a servo motor; an adapter sleeve 4, which is sleeved on the support shaft 2 and is provided with multiple, and multiple connecting frames 5 are provided on the adapter sleeve 4. The upper and lower sides of the connecting frames 5 are rotatably provided with rotating shafts 6; a placing frame 7, the upper and lower ends of which are respectively connected to the upper and lower rotating shafts 6 of the connecting frame 5; a fixing mechanism 8, which is arranged on the placing frame 7 and is used to fix the honeycomb panel; a transmission mechanism 9, which is arranged on the curing furnace body 1 and is used to drive the rotating shaft 6 to rotate.

[0041] When in use, after opening the curing furnace body 1, multiple honeycomb panels to be cured are placed vertically on each placement rack 7. At this time, the panels are placed vertically, and the bottom of the panels is in contact with the placement rack 7. Then the fixing mechanism 8 can be operated to press the upper end of the honeycomb panels on the placement rack 7, so as to clamp the panels and fix the panels on the placement rack 7. In this way, the panels can be cured stably in the future, and the instability and tipping of the panels can be avoided, thereby improving the curing quality and effect of the panels. After closing the curing furnace body 1, the curing heating is started, and the driving member 3 is started to drive the support shaft 2 to rotate. The support shaft 2 will drive the various connecting frames 5 thereon to rotate, and the connecting frame 5 will drive the placement rack 7 to rotate around the support shaft 2, so that the panels on the placement rack 7 will also rotate around the support shaft 2, so that the panels on the placement racks 7 at different positions can be heated evenly, and the curing effect of each panel is equal. Furthermore, when the support shaft 2 drives each connecting frame 5 to rotate, the connecting frame 5 will drive the rotating shaft 6 to revolve around the support shaft 2, and at the same time, the rotating shaft 6 itself will be driven to rotate through the transmission mechanism 9, that is, the rotating shaft 6 can also rotate while revolving around the support shaft 2, that is, when the rotating shaft 6 drives the placement frame 7 and the plate to revolve around the support shaft 2, the placement frame 7 and the plate will also rotate with the rotating shaft 6, so that all angles of the plate on the placement frame 7 will be displayed, thereby further making the heat curing of the plate more uniform and thorough, avoiding the current situation of static heating of the plate, and the plate can be effectively and comprehensively cured in a shorter time, which significantly improves the work efficiency and improves the processing quality of the plate.

[0042] The orientation angle of the plate placed on the placement rack 7 can be arbitrary, and the subsequent placement rack 7 will drive the plate to rotate evenly, avoiding the need for staff to repeatedly adjust the curing angle of the plate, saving a lot of manpower and time, and greatly improving work efficiency.

[0043] See also Figure 2-6 The fixing mechanism 8 includes: a screw 81, which is rotatably arranged on the upper end of the placement rack 7, a movable sleeve 82 is threadedly connected to the screw 81, and a pressing plate 83 is arranged at the lower end of the movable sleeve 82; a limiting component 84 is arranged on the placement rack 7, and is used to limit the rotation of the movable sleeve 82. When the plate is placed on the placement rack 7, by rotating the screw 81, the movable sleeve 82 is restricted by the limiting component 84, and the screw 81 will drive the movable sleeve 82 threadedly connected thereto to move downward, and the movable sleeve 82 will drive the pressing plate 83 to move, and finally the pressing plate 83 contacts the upper end of the honeycomb plate, thereby fixing the honeycomb plate on the placement rack 7.

[0044] In this embodiment, preferably, please refer to Figure 3-5The limiting component 84 includes a limiting slide bar 841 disposed on the placement frame 7, and a shift plate 842 is disposed on the movable sleeve 82. The limiting slide bar 841 movably penetrates the shift plate 842. Due to the cooperation between the limiting slide bar 841 and the shift plate 842, the movable sleeve 82 cannot rotate. The rotation of the screw rod 81 drives the movable sleeve 82 to move in the vertical direction. When the movable sleeve 82 moves, it drives the shift plate 842 to move along the limiting slide bar 841.

[0045] In this embodiment, preferably, please refer to Figure 2 , Figure 4 and Figure 7-8 The curing furnace body 1 has an annular groove 10 on its inner upper wall. The transmission mechanism 9 includes: a gear ring 91, which is arranged in the annular groove 10. The gear ring 91 is provided with a plurality of evenly distributed tooth blocks 92. A gear 93 is arranged on the rotating shaft 6 at the uppermost position. The plurality of gears 93 are meshed with the tooth blocks 92. When the support shaft 2 rotates to drive the plurality of rotating shafts 6 to rotate around it, the rotating shaft 6 will drive the gear 93 to revolve around the support shaft 2. At the same time, due to the meshing of the gear 93 and the tooth block 92, when the gear 93 revolves around the support shaft 2, the gear 93 will also drive the rotating shaft 6 to rotate, that is, the placement rack 7 and the plate will revolve while rotating.

The elastic member 16 in the present application can be a combination of a spring and a damper. When the pressure plate 83 contacts the upper end of the plate, it continues to drive the pressure plate 83 downward, and the pressure plate 83 will drive the transfer rod 15 to move toward the slide groove 14 and compress the elastic member 16. It can greatly prevent the situation where the pressure of the pressure plate 83 is too high and causes damage and deformation of the plate. When the plate is pressed and fixed, the transfer rod 15 has a partial moving effect, and at the same time, the elastic compression of the plate can also improve the protection effect of the plate.

[0047] In this embodiment, preferably, please refer to Figure 2-3The upper end of the screw rod 81 is provided with a push handle 11, and the upper wall of the placement rack 7 is provided with a plurality of limiting holes 12 distributed in an annular shape. The push handle 11 is provided with a through hole, and a limiting rod 13 matching the limiting hole 12 is threadedly connected in the through hole. The screw rod 81 can be conveniently driven to rotate by rotating the push handle 11. After the rotation is completed, the limiting rod 13 is located at the position of the limiting hole 12. Due to the telescopic effect of the transfer rod 15 relative to the movable sleeve 82, the limiting rod 13 can be kept at the corresponding position of the limiting hole 12. Then, the limiting rod 13 on the push handle 11 is rotated again, so that the limiting rod 13 is finally inserted into the limiting hole 12 of the placement rack 7. At this time, the push handle 11 and the screw rod 81 can be restricted and fixed to prevent the subsequent self-deflection of the screw rod 81, and the protective effect is good.

[0048] In this embodiment, preferably, please refer to Figure 1 and Figure 8 The inner wall of the slide groove 14 is provided with a slot 17, and the inner wall of the slot 17 is slidably provided with a sliding block 18, and the outer end of the sliding block 18 is connected to the transfer rod 15. When the transfer rod 15 moves along the slide groove 14, the transfer rod 15 drives the sliding block 18 to slide along the slot 17, thereby improving the smooth movement and stability of the transfer rod 15, and also limiting the transfer rod 15 to prevent it from leaving the slide groove 14.

[0049] In this embodiment, preferably, please refer to Figure 2 and Figure 4 The placement rack 7 is also provided with a positioning slot 19, and the pressing plate 83 is located above the positioning slot 19. When placing the plate on the placement rack 7, the plate can be placed vertically in the positioning slot 19 first, so that the plate can be initially restricted to prevent the plate from deflecting and tipping during the subsequent fixing process.
