[0087] In this embodiment, the second fixing seat 15 is composed of a first fixing portion 1501 and a second fixing portion 1502, and the two are arranged separately, and the first fixing portion 1501 and the second fixing portion 1502 are hinged and enclosed to form a second opening 16, which is convenient for installing and disassembling the second rotating shaft 17.

[0088] Specifically, Figures 7 to 8 As shown, the first fixing portion 1501 and the second fixing portion 1502 are detachably connected via screws, which facilitates installation and disassembly.

[0089] Specifically, the second fixed part 1502 includes a second bottom plate and a plurality of second vertical plates. The plurality of second vertical plates are spaced apart on the top of the second bottom plate. The plurality of second vertical plates and the first fixed part 1501 enclose a second opening 16. A second reinforcement block is provided between each two adjacent second vertical plates. The second reinforcement blocks are connected to the second bottom plate and the second vertical plates to improve the structural strength.

[0090] Specifically, the two sets of rotating mechanisms may adopt at least one of the above embodiments.

[0091] Based on the above implementation, in a preferred implementation, Figure 1 , Figure 6 and Figure 9As shown, at both ends of the platform body 1, there are slots 21 corresponding to the rotating mechanism respectively. A platform plate 34 is arranged in the slot 21. The bottom of the platform plate 34 is connected with a first support plate 23 through a plurality of support shafts 22. The support shafts 22 are arranged in the vertical direction, and a second support plate 25 is sleeved on the plurality of support shafts 22 through linear bearings 24. The rotating mechanism is arranged on the top of the second support plate 25. Among them, an opening for the rotating mechanism is provided on the platform plate 34.

[0092] In this embodiment, by providing the slot 21 and setting the second support plate 25 to be in sliding fit with the support shaft 22 in the vertical direction, it is convenient to drive the rotating mechanism to move in the vertical direction through the height adjustment mechanism to adjust the height of the rotating mechanism, so as to realize the height adjustment of the die head 30, and the rotating mechanism can be lowered below the top of the slot 21 to improve the aesthetics.

[0093] Specifically, as Figure 4 shown, a second bushing is sleeved on the support shaft 22 above the linear bearing 24 for limiting, so as to prevent the linear bearing 24 from hitting the platform plate 34 when rising, playing a protective role.

[0094] Specifically, as Figure 9 shown, a groove is provided on the top of the platform body 1 corresponding to the slot 21. The platform plate 34 is embedded in the groove, and the upper surface of the platform plate 34 is flush with the upper surface of the platform body 1 to ensure aesthetics.

[0095] Specifically, as Figure 1 、 Figure 3 and Figure 6 shown, a sealing plate is detachably connected to the opening. The upper surface of the sealing plate is flush with the upper surface of the platform plate 34 to ensure aesthetics. When the height of the rotating mechanism needs to be adjusted, the sealing plate is removed. After the adjustment is completed, the sealing plate is installed.

[0096] On the basis of the above implementation manner, in a preferred implementation manner, as Figure 3 、 Figure 4 and Figure 6As shown, the height adjustment mechanism includes two groups of lifting components 26, and the two groups of lifting components 26 are respectively arranged on the two first support plates 23; each group of lifting components 26 includes a screw 2601, a worm 2602, a worm wheel and a worm wheel seat 2603; the worm wheel is arranged in the worm wheel seat 2603, and the axial direction of the worm wheel is arranged in the vertical direction; the worm 2602 is arranged on the worm wheel seat 2603 in the horizontal direction, and the worm 2602 is meshed with the worm wheel; the screw 2601 is arranged in the vertical direction. The screw 2601 passes through the worm wheel, the worm wheel seat 2603 and the first support plate 23 in a vertical direction, and the top end of the screw 2601 is connected to the second support plate 25; the screw 2601 is coaxially arranged with the worm wheel and is threadedly connected with the worm wheel; wherein, the ends of the two worms 2602 facing each other are driven and connected by a transmission shaft 27; at least one set of lifting components 26 is provided with a second driving member 2604, and the second driving member 2604 is driven and connected to the end of the worm 2602 away from the transmission shaft 27.

[0097] It should be noted that the axial direction of the worm 2602 is parallel to the length direction of the die head 30 .

[0098] In this embodiment, when the height of the rotating mechanism needs to be adjusted, the worm 2602 in the lifting assembly 26 is driven to rotate by the second driving member 2604. Since the worm 2602 in the two groups of lifting assemblies 26 are connected by the transmission shaft 27, the two worms 2602 always rotate synchronously, thereby driving the two worm wheels to rotate synchronously. Since the worm wheel is threadedly connected to the screw 2601, the screw 2601 is driven to move up and down in the worm wheel, thereby driving the two groups of rotating mechanisms to move in the vertical direction on the two second support plates 25, thereby adjusting the height.

[0099] Specifically, the worm 2602 is connected to the transmission shaft 27 via a coupling, thereby improving the safety of torque transmission.

[0100] Specifically, Figure 3 As shown, each first support seat is provided with a bearing seat 35, and the transmission shaft 27 can be rotatably passed through the bearing seat 35, so as to improve the stability of the transmission shaft 27 when rotating.

[0101] Specifically, Figure 3 As shown, a plurality of bearing plates 32 are provided at intervals on the transmission shaft 27 , the bearing plates 32 are fixedly connected to the platform body 1 , and the bearing plates 32 are rotatably connected to the transmission shaft 27 , and the stability of the transmission shaft 27 during rotation is further improved by providing the bearing plates 32 .

[0102] Specifically, the structure of the second driving member 2604 is not specifically limited in this embodiment. The second driving member 2604 is a handwheel, which is used to drive the worm 2602 to rotate through the handwheel, so as to adjust the flipping angle of the die head 30. The second driving member 2604 can also be a driving motor, which drives the worm 2602 to rotate through the driving motor, saving time and effort. The second driving member 2604 can be arranged on a set of lifting assemblies 26, or can be arranged on both sets of lifting assemblies 26, and can be specifically selected according to the actual situation.

[0103] On the basis of the above implementation manner, in a preferred implementation manner, as Figure 6 shown, a positioning square tube 28 is provided at the bottom of the platform body 1. The positioning square tube 28 is spaced from the central position of the platform body 1 in the length direction by a preset distance, and is used for centering positioning when the trolley transports the die head 30 onto the platform body 1.

[0104] It should be noted that the distance between the positioning square tube 28 and the central position of the platform body 1 in the length direction is half of the width of the trolley, and can be specifically selected according to the actual situation.

[0105] In this embodiment, by providing the positioning square tube 28, when the trolley transports the die head 30 to the platform body 1, the front end of the trolley extends along the edge of the positioning square tube 28 to the bottom of the platform body 1, thereby completing the positioning, so that the die head 30 maintains a centered position in the length direction of the platform body 1.

[0106] Specifically, as Figure 1 、 Figure 2 and Figure 6 shown, a plurality of support feet 29 are provided at the bottom of the platform body 1 to facilitate the support of the platform body 1 and maintain stability.

[0107] Specifically, as Figure 1 shown, a protective cover 33 is covered outside between the first support plate 23 and the second support plate 25, which plays a role in protection and aesthetics.

[0108] The specific working principle of the die head disassembly and repair device provided in this embodiment is as follows: Taking the rotation mechanism of the first rotating shaft 4 as an example, when it is necessary to disassemble and repair the die head 30, the trolley transports the die head 30 between the two groups of rotation mechanisms under the positioning action of the positioning square tube 28, and connects the two ends of the die head 30 through the first connection holes 1303 on the first connecting piece 13 respectively. When it is necessary to rotate the die head 30, adjust the first locking piece 5 to the unlocking state and adjust the positioning column 10 to be separated from the first rotating shaft 4, and then drive the first rotating shaft 4 to rotate through the first driving piece 12, thereby driving the die head 30 to rotate until it reaches the preset angle. Then adjust the first locking piece 5 to the locking state and adjust the positioning column 10 to abut against the first rotating shaft 4 for limiting, thereby fixing the die head 30 to prevent the die head 30 from shaking. When it is necessary to adjust the height of the die head 30, drive the worm 2602 of the two groups of lifting components 26 to rotate simultaneously through the second driving piece 2604, and then drive the two screw rods 2601 to drive the second support plate 25 to move vertically along the support shaft 22, thereby realizing the adjustment of the height of the die head 30. The die head disassembly and repair device provided in this embodiment cooperates with the rotation mechanism and the height adjustment mechanism to adjust the die head 30 to a suitable height and angle, improving the flexibility of adjusting the die head 30, facilitating disassembly and repair, with a simple adjustment method, avoiding damage to the die head 30 and injury to personnel caused by manually moving and flipping the die head 30, saving time and effort, improving the maintenance efficiency, and solving the technical problem that the existing method of manually disassembling and maintaining the coating die head 30 is time-consuming and laborious and easily causes damage to the coating die head 30.

And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
