DETAILED DESCRIPTION

[0023] The following is a detailed description of the present invention with reference to the accompanying drawings. Figures 1 to 4 shown.

[0024] Example: See Figures 1 to 4 A rotating expansion device comprises: an expansion mechanism 2 and a rotating mechanism 1, wherein the expansion mechanism 2 comprises a vertical plate 21, the lower end of the vertical plate 21 is movably connected with two expansion rod assemblies, and the vertical plate 21 is provided with a driving structure for driving the two expansion rod assemblies to rotate and expand; the rotating mechanism 1 is located above the vertical plate 21, and is connected to the vertical plate 21 and can drive the vertical plate 21 to rotate.

[0025] The rotary spreading device of the present technical solution achieves the purpose of spreading the surface of the flexible object and the effect of driving the flexible object to rotate during the spraying process by setting a spreading mechanism 2 and a rotating mechanism 1. In specific implementation, the rotating mechanism 1 drives the vertical plate 21 to rotate slowly. The rotating mechanism 1 can be a rotating motor 11 alone, or a combination of the rotating motor 11 and other transmission mechanisms, such as a combination of the rotating motor 11 and the reducer 13, and a rotating seat can also be added; secondly, when the spreading mechanism 2 is working, in the initial state, the two spreading rod assemblies can be set in parallel or with the lower ends close together; then the flexible part is put on the two spreading rod assemblies, and then the driving structure starts to drive the two spreading rod assemblies to move, and the lower ends of the two spreading rod assemblies rotate outward and spread, while also spreading the flexible object.

[0026] See also Figure 1 、 Figure 3 The expansion rod assembly includes an expansion rod 24, the upper end of the expansion rod 24 is connected to a connecting head 22, the connecting head 22 is rotatably connected to the vertical plate 21, and the connecting head 22 can rotate relative to the vertical plate 21. The driving structure includes a driving member fixed to the vertical plate 21, and the lower end of the driving member is driven and connected to a driving plate 217. A transmission rod assembly is connected between the driving plate 217 and the connecting head 22. When the driving member drives the driving plate 217 to move up and down, the driving plate 217 drives the connecting head 22 to rotate through the transmission rod assembly.

[0027] In order to facilitate the driving of the expansion rod assembly to rotate relative to the vertical plate 21, the expansion rod assembly is set as a combination of the expansion rod 24 and the connecting head 22. The connecting head 22 drives the expansion rod 24 to rotate together. Secondly, the driving member is connected to the connecting head 22 through the transmission rod assembly. In actual application, the driving member drives the driving plate 217 to move up and down. When the drive moves up and down, the connecting head 22 is driven to rotate through the transmission rod assembly, thereby driving the expansion rod 24 to rotate.

[0028] See also Figure 1 、 Figure 3 The transmission rod assembly includes a first transmission rod 27 and a second transmission rod 26. One end of the first transmission rod 27 is connected to the connecting head 22, and the other end of the first transmission rod 27 is hinged to one end of the second transmission rod 26; the driving plate 217 is provided with a vertical section 218, and the other end of the second transmission rod 26 is hinged to the vertical section 218.

[0029] The transmission rod assembly is set to two transmission rods. When the driving plate 217 moves up and down, the driving plate 217 drives the other end of the second transmission rod 26 to move downward, one end of the second transmission rod 26 drives the first transmission rod 27 to rotate, and the first transmission rod 27 drives the connecting head 22 to rotate.

[0030] The transmission assembly can also have other structures, including a main transmission rod with an inclined movable groove. The vertical section 218 of the drive plate 217 is connected to the drive rod, and one end of the drive rod is inserted into the movable groove. When the drive plate 217 is raised or lowered, the drive rod is also driven up or down, and the drive rod moves in the movable groove, driving the main transmission rod to rotate. The rotation of the main transmission rod then drives the connector 22 to rotate.

[0031] Furthermore, the upper end of the connecting head 22 is U-shaped, and the upper end of the connecting head 22 is connected to the rotating shaft 210 and is connected to the vertical plate 21 through the rotating shaft 210, and the rotating shaft 210 is hinged to the first transmission rod 27. The connecting head 22 is provided with a connecting hole, and the first transmission rod 27 is connected to a connecting column 211, and one end of the connecting column 211 is inserted into the connecting hole.

[0032] This technical solution simplifies the structure by placing the upper end of the connector 22 in a U-shape. The upper end of the connector 22 is plugged into the vertical plate 21 and is rotationally connected to the vertical plate 21 via a rotating shaft 210. The first transmission rod 27 is also rotationally connected to the rotating shaft 210, and the first transmission rod 27 can rotate relative to the rotating shaft 210. The connector 22 and the first transmission rod 27 are connected by a connecting column 211, and the first transmission rod 27 drives the connector 22 to rotate via the connecting column 211.

[0033] Furthermore, the support rod 24 is a blind tube with an open upper end, the lower end of the connecting head 22 is provided with a plug hole that matches the blind tube, the upper end of the blind tube is inserted into the connecting head 22, and the side of the connecting head 22 is connected to an inflation interface 28, one end of the inflation interface 28 extends into the blind tube, and the side of the blind tube is provided with multiple air outlet holes 25.

[0034] In order to assist in expanding the flexible object, the present technical solution also provides an inflation structure, and the expansion rod 24 is set as a blind tube. When in use, the flexible object is put on the outside of the expansion rod 24, and the blind tube is inflated through the inflation interface 28, and the gas is discharged from the air outlet 25; then the flexible object is inflated and expanded.

[0035] See also Figure 3 、 Figure 4 The driving component includes a servo electric cylinder 213, the vertical plate 21 is connected to a bracket, the bracket includes a support plate 215, the servo electric cylinder 213 is fixed to the support plate 215, one end of the support plate 215 is connected to the lower end of the vertical plate 21, and reinforcement blocks 214 are provided between the two sides of the support plate 215 and the vertical plate 21. The servo electric cylinder 213 is provided with a screw 216, and the driving plate 217 is provided with a threaded hole and is threadedly connected to the screw 216.

[0036] This technical solution uses a servo electric cylinder 213 as the driving element. The servo electric cylinder 213 is threadedly connected to the drive plate 217 via a screw 216. The rotation of the screw 216 drives the drive plate 217 to rise and fall, thereby achieving high lifting precision of the drive plate 217. Secondly, to facilitate the fixing of the servo electric cylinder 213, this technical solution provides a bracket to fix the servo electric cylinder 213.

[0037] See also Figure 1 、 Figure 2 The driving member is a cylinder 212, a push rod of the cylinder 212 is connected to the driving plate 217, and drives the driving plate 217 to move up and down.

[0038] When the driving member is an air cylinder 212, the expansion rod 24 can be quickly pushed open, which is convenient to use.

[0039] See also Figure 1 、 Figure 2 The upper end of the vertical plate 21 is provided with a receiving plate 29, which is connected to the rotating mechanism 1.

[0040] During specific use, the rotating motor 11, the reducer 13, the transmission mechanism 12, etc. are all fixed to the horizontal support plate 14. The rotating motor 11 drives the reducer 13 to rotate through the transmission mechanism 12, and drives the rotating seat to rotate; the rotating seat drives the receiving plate 29 and the vertical plate 21 to rotate, thereby realizing a 360-degree rotation of the expansion mechanism 2. Of course, the reducer 13 can also be directly connected to the receiving plate 29, and the output shaft of the reducer 13 can be connected to the receiving plate 29 to directly drive the receiving plate 29 to rotate.

[0041] Preferably, the transmission mechanism 12 includes a gear transmission mechanism, a belt transmission mechanism or a synchronous belt transmission mechanism.
