Description

Technical Field

[0001] The invention relates to the technical field of hot-dip galvanizing processes, in particular to an automatic turning and unloading device. Background Art

[0002] In the hot-dip galvanizing process of small workpieces, a mesh basket is usually used to load multiple small workpieces, and then the mesh basket is immersed in a hot-dip galvanizing pool. It is soaked at a suitable temperature for a period of time so that a zinc layer adheres to the surface of the workpiece. The mesh basket is then lifted and the small workpieces in the mesh basket are poured into the inside of a centrifuge. The excess zinc liquid on the surface of the small workpiece is removed by high-speed centrifugation. The workpiece is then taken out of the centrifuge to obtain a galvanized part, and the zinc is recovered at the same time.

[0003] However, during the entire operation, the hot-dip galvanized workpiece needs to be moved to the centrifuge first, then turned over and dumped, and the workpiece is poured out of the centrifuge after the centrifugation is completed. During the entire process, the workpiece needs to go through multiple rounds of rotation. On the one hand, the operation is more troublesome. On the other hand, zinc liquid is adhered to multiple tools. After zinc leaves the galvanizing pool, the temperature drops rapidly and it will soon solidify, resulting in zinc liquid adhered to multiple tools. This makes it difficult to recover the residual zinc, the recovery rate is low, and it also increases the risk of the entire operation process. For this reason, an automatic turning and dumping device is specially provided for quickly and conveniently transferring workpieces and recovering zinc materials during the centrifugal removal of residual zinc for small workpieces after hot-dip galvanizing.

[0047] 1.

[0048] 2. The automatic flipping and unloading device is designed with a dedicated storage unit. When loading, the storage unit relies on the outer cover tube to prevent the zinc liquid from splashing outward, which is safer and effectively ensures that the zinc liquid is recovered into the U-shaped receiving container. During centrifugal operation, the excess zinc liquid on the surface of the workpiece inside the hollow cylinder is dispersed away from the center, causing the zinc liquid to pass through the hollow cylinder and splash onto the inner wall of the cylinder. At the same time, the cylinder also rotates at high speed under the action of the centrifugal turntable, and the discharge channel between the cylinder and the hollow cylinder expands downward in a conical shape, causing the zinc liquid to flow out rapidly downward along the inner wall of the cylinder and finally discharged into the U-shaped receiving container through the discharge chute. In this way, the zinc liquid can be quickly recovered by centrifugation without the need for additional zinc material recovery processing in the centrifuge, further reducing the recovery difficulty.

[0078] The outer cover tube 31 includes a cylinder 311, a swivel 313, a positioning frame 314, a conical self-flowing platform 316, a connecting positioning ring 317, a transmission connecting shaft 318 and a discharge groove 319.

The positioning bar 323 is movably inserted in the positioning slot 315, and the fixing stud 324 passes through the conical self-flowing platform 316.

[0080] A discharge channel 312 is formed between the cylinder 311 and the hollow portion 321 , and the bottom end of the discharge channel 312 expands downward in a conical shape. A discharge groove 319 is opened at the bottom end of the discharge channel 312 .

[0081] Working principle: When the device is in use, multiple storage units 3 are installed in the annular assembly space composed of the fixed half ring 265 and the movable half ring 266, and then by starting the servo motor 24, the servo motor 24 drives the transmission shaft 25 to rotate, and the transmission shaft 25 drives the rotating seat 23 at its top to rotate, so that the multiple storage units 3 revolve around the transmission shaft 25 as the axis;

[0082] During the synchronous rotation of multiple storage units 3, one group of storage units 3 rotates to the position of the feed hopper 13, at which time the servo motor 24 stops, the flip stop rod 210 abuts against the bottom end of the outer cover tube 31, causing the outer cover tube 31 to twist, and the rotating support arm 262 twists at the front end of the fixed support arm 261, causing the outer cover tube 31 to be tilted, with the bell mouth 322 facing the feed hopper 13, waiting for loading, at which time the small workpieces that have been hot-dip galvanized are poured into the feed hopper 13, and the workpieces slide down into the hollow part 321 through the inclined inner wall of the hollow part 321, and at this time part of the zinc liquid passes through the hollow part 321 and flows to the inner wall of the cylinder 311, and then drips down from the discharge trough 319 at the bottom into the U-shaped receiving container 12;

[0083] Then the servo motor 24 is started again, so that the storage unit 3 filled with workpieces continues to rotate, and as the storage unit 3 moves, its bottom end is separated from the flip block rod 210. At this time, under the action of gravity, the storage unit 3 is in an open vertical upward state. When the storage unit 3 moves to the centrifugal station 14, the servo motor 24 stops, and the electric telescopic rod 264 is started to shrink its output end, driving the storage unit 3 to move downward. By installing a centrifugal turntable at the centrifugal station 14 and starting the centrifugal turntable at low speed, as the storage unit 3 slowly moves downward, the cylinder 311 is connected to the centrifugal turntable through the transmission connecting shaft 318 at its bottom end. At this time, the centrifugal turntable is started at high speed, driving the entire storage unit 3 to rotate at high speed. At this time, the swivel 313 rotates inside the anti-slip groove 267.

[0084] At this time, under the action of centrifugal force, the excess zinc liquid on the surface of the workpiece inside the hollow cylinder 32 is dispersed away from the center, so that the zinc liquid passes through the hollow cylinder 32 and splashes on the inner wall of the cylinder 311. At the same time, the cylinder 311 is also rotating at a high speed under the action of the centrifugal turntable, and the discharge channel 312 between the cylinder 311 and the hollow cylinder 32 expands downward in a conical shape. Therefore, under the action of centrifugal force, the zinc liquid will flow out rapidly downward along the inner wall of the cylinder 311, and finally be discharged into the U-shaped receiving container 12 through the discharge trough 319, completing the excess zinc removal operation. Then the centrifugal turntable slows down to a stop, and the output end of the electric telescopic rod 264 extends outward, so that the storage unit 3 moves upward and rises to separate from the centrifugal turntable.

[0085] Then the servo motor 24 is started again, driving the rotating seat 23 to rotate. During the rotation process, the fixed arm 261 is always moving on the support ring 27 to prevent the front end of the fixed arm 261 from bending due to gravity. When the fixed arm 261 rotates to the workpiece unloading channel 15, the driving gear 269 inside the fixed arm 261 engages and rotates with the tooth groove 29, so that the rotating arm 262 rotates at the front end of the fixed arm 261 while following the rotation of the rotating seat 23, thereby causing the storage unit 3 to flip up and down. The workpiece 261 is turned upside down, so that the workpiece with the residual zinc recovered inside falls downward into the workpiece unloading channel 15, and then slides through the unloading port 17 to the workpiece unloading hopper 16, completing the automatic flipping and unloading of the workpiece. Then the fixed arm 261 continues to move downward, and the rotating arm 262 continues to rotate. When the driving gear 269 is separated from the tooth groove 29, the rotating arm 262 completes a 360-degree rotation, so that the storage unit 3 is reset to the state with the opening vertically facing upward. At this time, the rotating seat 23 continues to rotate, so that the storage unit 3 moves to the position of the feed hopper 13 again, waiting for secondary loading.

[0086] In this way, the cyclic material receiving, centrifugal removal of residual zinc and automatic turning and unloading operations are realized, with a high degree of automation. The entire process only uses the storage unit 3 to store the workpieces leaving the galvanizing tank, reducing the workpiece circulation operation and making the operation convenient. At the same time, the zinc liquid is in the U-shaped receiving container 12 from the time of loading to the end of centrifugation, realizing effective recovery of the zinc material, convenient recycling, and high recovery rate. During the circulation process, the workpieces that have completed the residual zinc recovery are automatically turned and unloaded at the workpiece unloading channel 15, without the need for manual auxiliary control, which is more convenient.

[0087] The most important thing is that, by designing a dedicated storage unit 3, the storage unit 3 can tilt sideways by flipping the baffle 210 when loading, which facilitates feeding. At the same time, the outer cover tube 31 prevents the zinc liquid from splashing outward, which is safer and effectively ensures that the zinc liquid is recovered into the U-shaped receiving container 12. During the centrifugal operation, there is no need to transfer the workpiece. Through the specially designed discharge channel 312 and the conical gravity table 316, the zinc liquid can quickly and effectively pass downward through the discharge trough 319 for recovery during the centrifugal process, resulting in a high recovery rate and no need for additional zinc material recovery processing on the centrifugal turntable.

[0088] The zinc material entering the U-shaped receiving container 12 condenses naturally. By applying an oily coating on the inner wall of the U-shaped receiving container 12 and the storage unit 3, the zinc material will not adhere to the surface when solidifying, making it more convenient to recover the residual zinc.
