[0002] The intelligent suspension conveying system is an upgraded version of the traditional suspension conveying system. It mainly realizes the intelligence and high efficiency of material conveying by integrating technologies such as sensors, the Internet of Things, and automatic control. Its main core structures include a track and a spreader system, a drive and control unit, a perception and feedback device, a data interaction system, etc. Currently, the intelligent suspension conveying system is widely used in the rubber products industry. At present, there are certain deficiencies in the conveying of annular rubber workpieces by such intelligent suspension conveying devices: Generally, the spreaders used for suspension conveying adopt hooks to hang the materials. However, for semi-finished products, the materials themselves are soft and easy to deform. The pressure at the contact part between the hook and the material is relatively large and continuously pressured during the conveying process, which is likely to cause deformation at the contact point of the material. Moreover, the stability of hanging the material with the hook is insufficient, and the shaking and vibration during movement will increase the occurrence probability of the above deformation situation. Secondly, the semi-finished rubber materials may need to be conveyed to the vulcanization or spraying station subsequently. There are dead corners at the contact points between the hooks and the materials compared with other positions during heating or spraying, reducing the production quality. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a suspension conveying device and a feeding method for processing annular rubber workpieces.

[0021] Embodiment 1: Please refer to Figures 1 - 3, a suspension conveying device, comprising a track 1 and a hanger 2 mounted on the track 1, and also comprising an output rack 3 fixed below the track 1, wherein the hanger 2 comprises a bracket 4, a transmission assembly 5 mounted on the bracket 4, and two symmetrically distributed supports 6 mounted at the bottom end of the bracket 4; The support 6 includes a plurality of movable rollers 61 distributed in an annular array, and the plurality of movable rollers 61 are used to support the annular rubber workpiece from the inside. The support 6 also includes an adjustment component 62 for simultaneously adjusting the positions of the plurality of movable rollers 61; The transmission assembly 5 is in transmission connection with the output rack 3 and a plurality of movable rollers 61, and the output rack 3 and the transmission assembly 5 are used to drive the movable rollers 61 to rotate; Before the sling 2 transports the annular rubber workpiece, the annular rubber workpiece is sleeved on the outside of multiple movable rollers 61, and the movable rollers 61 provide support for the annular rubber workpiece. When the sling 2 moves with the track 1, the output rack 3 forces the transmission assembly 5 to operate. When the transmission assembly 5 operates, it forces the multiple movable rollers 61 to rotate, thereby driving the annular rubber workpiece to rotate, thereby changing the contact point between the movable rollers 61 and the annular rubber workpiece.

[0022] Among them, a chain is arranged inside the track 1, and the chain is driven by the servo control system of the track 1, and drives multiple groups of hangers 2 to move at the same time. Two supports 6 are respectively installed with two annular rubber workpieces, and at least three movable rollers 61 are arranged. When in use, the annular rubber workpiece is sleeved on the outside of multiple movable rollers 61, and the movable rollers 61 provide a supporting effect for the inside of the annular rubber workpiece. When the hanger 2 moves, the output rack 3 drives the transmission component 5. After the transmission component 5 is running, it drives the two groups of movable rollers 61 at the bottom of the hanger 2 to rotate simultaneously. When the movable roller 61 rotates, the friction force is used to drive the annular rubber workpiece to rotate, that is, the annular rubber workpiece rotates while moving with the hanger 2. When the annular rubber workpiece rotates, the contact point between the movable roller 61 and the annular rubber workpiece changes, that is, the support point of the annular rubber workpiece by the movable roller 61 changes; By arranging a plurality of annularly distributed movable rollers 61 on the sling 2 to replace the hooks for lifting the annular rubber workpiece, the inside of the annular rubber workpiece can be supported, the stability is improved, and the vibration and shaking during the transportation process are reduced. In addition, during the transportation process, the output rack 3 and the transmission assembly 5 can drive each movable roller 61 to rotate synchronously, so that the annular rubber workpiece can rotate while moving, thereby avoiding deformation due to continuous pressure at the same position, and making the annular rubber workpiece more uniform during heating or spraying, avoiding dead corners, and improving the processing quality.

When the second bevel gear 67 rotates, it drives the base shaft 66 to rotate. When the base shaft 66 rotates, it drives the movable roller 61 to rotate. When a plurality of movable rollers 61 rotate, they drive the annular rubber workpiece to rotate self - sufficiently, thereby changing the support points inside the annular rubber workpiece; By setting the transmission assembly 5 and the output rack 3, when the spreader 2 moves, the output rack 3 drives the transmission assembly 5 to operate, thereby driving a plurality of movable rollers 61 to rotate simultaneously, which is beneficial to driving the annular rubber workpiece to rotate self - sufficiently, so as to change the support points, avoid deformation of the annular rubber workpiece, and ensure the production quality.

[0027] Embodiment 4, refer to Figures 5 - 8 , different from the above - mentioned embodiment, the adjusting assembly 62 includes a plurality of guide rails 621 distributed in an annular array.

The worm gear 626 is movably sleeved on the cross - tube 42. A worm 627 is engaged with the top of the worm gear 626. Both ends of the worm 627 are movably installed on the guide rail 621 through auxiliary bearing seats 628. The transmission rod 64 includes a sleeve 641 and a plug rod 642 inserted into the sleeve 641. Uniformly distributed strip - shaped tooth blocks are arranged on the plug rod 642. Tooth grooves matching the strip - shaped tooth blocks are provided inside the sleeve 641.

[0028] Among them, the number of guide rails 621 and arc-shaped frames 625 is the same as that of the movable rollers 61 and they correspond one by one. During use, the diameters of the annular rubber workpieces in different batches are different. When conveying annular rubber workpieces with different diameters, the worm 627 is rotated. When the worm 627 rotates, it drives the worm gear 626 to rotate. When the worm gear 626 rotates, it drives the rotating frame 624 to rotate. At this time, when the rotating frame 624 rotates around the horizontal pipe 42, it simultaneously drives a plurality of arc-shaped frames 625 to swing. When the arc-shaped frames 625 swing, they push the connecting shaft 623, thereby causing the radial slider 622 to slide along the slide rail.

When the pressing plate 11 moves, it drives the incomplete rack 10 to slide and compresses the spring 14. When the incomplete rack 10 slides, it meshes with the transmission gear 9 and pushes the transmission gear 9 to rotate. When the transmission gear 9 rotates, it drives the worm 627 to rotate, thereby causing the adjusting assembly 62 to operate. When the adjusting assembly 62 operates, it drives a plurality of movable rollers 61 to move and contract. At this time, the annular rubber workpiece can be installed or disassembled.
