[0028] Reference Figure 1 as well as Figure 2 A coating oven hull lifting mechanism includes a box body 1 and a bellows hull 2 arranged on the box body 1, and also includes a lifting structure 3 for driving the bellows hull 2 to lift and lower. The lifting structure 3 is connected to the bellows hull 2, and when the lifting structure 3 is in operation, it can drive the bellows hull 2 to lift and lower.
[0029] Specifically, the bellows hull 2 is arranged in the box body 1, and the bellows hull 2 includes an upper bellows 21 and a lower bellows 22. In this embodiment, the position of the upper bellows 21 is fixed, and the lower bellows 22 is connected to the lifting structure 3. The lifting structure 3 drives the lower bellows 22 to move toward or away from the upper bellows 21.
[0030] The lifting structure 3 includes a lifting assembly 31 disposed on the box body 1 and a driving assembly 32 for driving the lifting assembly 31. The lifting assembly 31 includes a first screw lifting group 311 and a second screw lifting group 312 disposed above the box body 1. In this embodiment, since the bellows hull 2 is generally in a rectangular shape, in order to achieve stable support for the bellows hull 2 for driving, the first screw lifting group 311 and the second screw lifting group 312 are disposed at the four corners of the bellows hull 2.
[0031] The first screw lifting group 311 has the same structure as the second screw lifting group 312. The second screw lifting group 312 is arranged on the other side of the box body 1 relative to the first screw lifting group 311 to support the other side of the lower bellows 22. Taking the first screw lifting group 311 as an example, the first screw lifting group 311 includes two first supports 3111 arranged on one side of the box body 1. The first support 3111 is provided with a first screw lift 3112 and an active lifting shaft 3113 arranged on the first screw lift 3112. The active lifting shaft 3113 is provided with a driven lifting shaft 3115 facing the bellows hull 2. A connecting member 3114 is provided at the connection between the active lifting shaft 3113 and the driven lifting shaft 3115. In this embodiment, the connecting member 3114 is specifically a flange plate, and in other embodiments, it can be other mechanical connecting parts.
[0032] When the first screw lift 3112 is in operation, the first screw lift 3112 will drive the active lift shaft 3113 to move or descend in the vertical direction, thereby driving the driven lift shaft 3115 to move, and the moving driven lift shaft 3115 will apply a force to the lower bellows 22 to approach the upper bellows 21, thereby driving the lower bellows 22 to move in the direction close to the upper bellows 21. The structure and working principle of the screw lift are both existing technologies and can be purchased. You can choose a specific model when actually using it.
[0033] The driven lifting shaft 3115 is connected to the lower bellows 22 of the bellows hull 2. In order to be adapted and installed with the lower bellows 22, the lower bellows 22 has a connecting block 221 connected to the first screw lifting group 311 and the second screw lifting group 312, and the connecting block 221 is connected to the driven lifting shaft 3115. In this embodiment, in order to facilitate disassembly and installation, a through hole is opened in the connecting block 221, and the driven shaft is passed through the through hole and fixed to the connecting block 221 by threaded connection; at the same time, the connecting block 221 is threadedly connected to the side wall of the lower bellows 22. Through such a configuration, the connection between the screw lifting group and the lower bellows 22 can be easily maintained and repaired.
[0034] In addition, in order to avoid the uncontrolled fall of the lower hull, the operational stability and safety of the hull lifting mechanism are increased. The first support 3111 is provided with a limit block 31111 for limiting the movement of the active lifting shaft 3113. In this embodiment, the limit block 31111 is located below the connecting member 3114, and the area of the limit block 31111 is smaller than the area of the connecting member 3114. The active lifting shaft 3113 is in contact with or disengaged from the limit block 31111. By providing the limit block 31111, when a sudden break or control failure occurs, the limit block 31111 can control the falling stroke of the lower bellows 22 by limiting the falling of the connecting member 3114.
[0035] The driving assembly 32 includes a motor 321 disposed on the housing 1, a first transmission shaft 322 and a second transmission shaft 323 disposed on the motor 321, the first transmission shaft 322 is connected to the first screw lifting group 311, and the second transmission shaft 323 is connected to the first screw lifting group 311 and the second screw lifting group 312. In this embodiment, the first transmission shaft 322 is connected to the motor 321 and the two first screw lifts 3112 through a coupling, and the second transmission shaft 323 is connected to the first screw lift 3112 and the corresponding second screw lift through a coupling. By starting the motor 321, the first screw lifting group 311 and the second screw lifting group 312 can be driven to move through the first transmission shaft 322 and the second transmission shaft 323. In addition, since the motor 321 has a power-off brake function, it can cooperate with the limit block 31111 to limit the fall of the lower bellows 22 when encountering a power outage.
[0036] Reference Figure 3 and Figure 4 In addition, the coating oven hull lifting mechanism also includes a guide structure 4, which includes a plurality of guide rods 41 arranged on the box body 1, the guide rods 41 are located on the side of the bellows hull 2, and the lower bellows 22 has a corresponding guide block 222, and the guide block 222 is slidably connected with the guide rod 41. In this embodiment, there are four guide rods 41, which are respectively located at the four corners of the lower bellows 22. At the same time, the guide rod 41 is provided with a stopper 411 for blocking the guide block 222, and the stopper 411 extends along the radial direction of the guide rod 41, and the guide block 222 contacts or disengages from the stopper 411. By setting the stopper 411, the lower bellows 22 can be further limited in cooperation with the limit block 31111, thereby further increasing the working stability and safety. It can be understood that the position of the stopper 411 can be adjusted according to actual needs and processing technology.
[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
