Description

Technical Field

[0001] The present invention relates to a docking device that self-aligns the center and self-seals for a moving target, belonging to the technical field of dryers. Background Art

[0002] Currently, for a double-cone dryer applicable to the drying industry, its cylinder rotates around the central axis during normal operation. When the process ends and discharging is required, it stops rotating, and the discharging port on the cylinder is manually opened. The material falls into a trolley on the ground and is then pushed away manually to the next working station. Similar feeding and discharging in various industries are mostly like this, where manual workers collect the material with containers at the outlet or pour the material into the cylinder little by little. This has low efficiency, high labor intensity, is prone to environmental pollution, and there are also many accidents. More importantly, the above situation cannot achieve automated production like that of an assembly line. Summary of the Invention

[0003] The object of the present invention is to provide a docking device that self-aligns the center and self-seals for a moving target, with a simple structure and capable of meeting the needs of assembly line production. In order to improve production efficiency, the present invention can not only quickly dock when the interfaces are aligned with each other in position, but also, when the centers of the interfaces are not aligned, i.e., not concentric, it can be automatically aligned and then sealed and docked to form a channel for the medium to pass through.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A docking device that self-aligns the center and self-seals for a moving target, including an interface, a spherical plain bearing, a cylinder, a base plate, a ball head rod, a base, a first flange, a sleeve, a piston body, a long shaft, several springs, a small shaft, a second flange, a movable interface, a cylinder body, a material delivery pipe, and a reversing valve; the interface is connected to the cylinder through a spherical plain bearing, and the cylinder, the base plate, and the ball head rod are bolted together as a whole; the ball head rod is movably connected to the base; the interface, the piston body, the springs, the small shaft, and the second flange are welded together as a whole; the long shaft is bolted to the first flange, and the sleeve and the first flange are welded together as a whole; the movable interface is welded to the valve on the cylinder body; the reversing valve is connected to the cylinder through a conduit; the material delivery pipe is movably connected to the sleeve.

[0006] Preferably, the outer contour of the interface is spherical.

[0007] Preferably, one end of several of the springs abuts against the first flange, and the other ends of several of the springs are welded to the second flange.

[0008] Preferably, the base is provided with a groove, the ball head rod is arranged in the groove, and the head of the ball head rod is a sphere.

[0009] Beneficial effects:

[0010] 1) The present invention makes it possible to form a production line of multiple drying machines for automated production, improving productivity, reducing labor intensity, and also reducing environmental pollution. This device can also be applied to similar occasions in other industries;

[0011] 2) The present invention can solve the problem that when the centers of the discharge port and the receiving port in production are not aligned, i.e., not concentric, it forms a passage for the medium to pass through;

[0012] 3) The interface of the present invention is spherical. When the spherical surface of one interface can contact the inner conical surface of the movable interface, it is the most labor-saving sealing contact, which can self-align the center, and at the end of the contact process, the two are always in a sealed state.

Detailed implementation manners

[0026] The following makes several improvements and refinements to the present invention in conjunction with the attached drawings, and these improvements and refinements should also be regarded as the protection scope of the present invention.

[0027] As Figures 1-12 shown, a docking device that self-aligns the center and self-seals for a moving target includes interface 1, spherical plain bearing 2, cylinder 3, bottom plate 4, ball head rod 5, base 6, first flange 7, bushing 8, piston body 9, long shaft 10, several springs 11, small shaft 12, second flange 13, movable interface 14, cylinder body 15, material conveying pipeline 16 and reversing valve 17; the interface 1 is connected to the cylinder 3 through the spherical plain bearing 2, and the cylinder 3, the bottom plate 4 and the ball head rod 5 are bolted together as a whole; the ball head rod 5 is movably connected to the base 6; the interface 1, the piston body 9, the springs 11, the small shaft 12 and the second flange 13 are welded together as a whole; the long shaft 10 is bolted to the first flange 7, and the bushing 8 and the first flange 7 are welded together as a whole; the movable interface 14 is welded to the valve on the cylinder body 15; the reversing valve 17 is connected to the cylinder 3 through a conduit; the material conveying pipeline 16 is movably connected to the bushing 8.

[0028] Preferably, the outer contour of the interface 1 is spherical.

[0029] Preferably, one end of several of the springs 11 abuts against the first flange 7, and the other ends of several of the springs 11 are welded to the second flange 13.

[0030] Preferably, a groove is provided on the base 6, the ball head rod 5 is disposed in the groove, and the head of the ball head rod 5 is a sphere.

[0031] In the present invention, by changing the wire diameter and the number of strands of the spring 11, or the lengths of the small shaft 12 and the long shaft 10, the stiffness during the overall extension and retraction of the interface 1 can be adjusted.

[0032] In the present invention, by changing the materials of the inner conical surface of the discharge port 14 and the spherical surface of the interface 1, the degree of seal leakage can be adjusted to meet the seal requirements when different media flow.

[0033] In the present invention, when the external force acting on the spring 11 laterally is released, the spring 11 will return to its initial state.

[0034] Working principle: When the interface 1 on a fixed pipeline needs to be docked with the discharge port 14 as the moving target on the rotating cylinder 15, first issue an instruction to decelerate and then stop the cylinder 15. When the dynamic discharge port 14 stays at the set position, with both the rotational error and the axial error being zero, the cylinder 3 will automatically extend. The associated interface 1 will extend simultaneously under the action of the cylinder and come into contact with the discharge port 14, directly entering the bottom of the conical surface of the discharge port 14 to form a sealed connection and create a pipeline channel.

[0035] This device allows a certain deviation in the concentricity between the center of the interface 1 and the discharge port 14. When the centers of the interface 1 and the discharge port 14 are misaligned, including angular deviation and axial deviation, after the cylinder 3 receives an instruction to extend, it drives the interface 1 to touch the discharge port 14. The spherical surface of the interface 1 contacts the inner conical surface of the discharge port 14 and will slide along the inner conical surface into its interior until it is blocked. The contact surface between the interface 1 and the discharge port 14 is a respective circumferential line of equal size and they overlap each other, playing a sealing role.

[0036] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the premise of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
