[0043] The support clamping position 22 is a C-shaped support clamping position.

[0044] The bracket 14 and the support clamp 22 are provided with a plurality of raised anti-fall limit blocks around the net to prevent the net from falling when it is turned over.

[0045] The Dacromet coating tank 30 is arranged below the dip coating centrifugal support frame 20, and includes a tank body 31 and a plurality of lifting cylinders 32 arranged outside the tank body 31 to drive the tank body to move up and down. The size of the tank body 31 is adapted to the diameter of the dip coating centrifugal support frame 20.

[0046] The grabbing structure 18 includes a sliding plate 181, both ends of which are connected to the rodless cylinders 12 on both sides, two third cylinders 182 are symmetrically arranged on the sliding plate 181, and a connecting plate 183 is arranged at the bottom of the sliding plate 181. The connecting plate 18 is a door-type structure, and a fourth cylinder 184 is symmetrically arranged on both sides of the connecting plate 183. The piston rod end of each fourth cylinder 184 is connected to a grabbing plate 185, and the grabbing plate 185 is an L-shaped plate structure.

[0047] The first cylinder is used to lower the hopper into the basket, and the switch at the bottom of the hopper is turned on to allow the material to fall into the basket. The grabbing structure pushes and pulls the grab plate through the fourth cylinder, and the edge of the basket is hooked by the L-shaped structure of the grab plate, which is then grabbed by the third cylinder. The basket and the batch of materials are sent into the Dacromet through the transmission of the rodless cylinder. After the immersion centrifugation is completed, the basket is grabbed by the grabbing structure and removed.

[0048] The front end of the feeding device 40 is also provided with a loading device 60 and a conveying device 70 which cooperate with each other in sequence. The loading device 60 is used to feed the conveying device 70 .

[0049] like Figure 6-10 As shown, the feeding device 40 includes a fixed frame 41 and a hopper 42, a slide rail 44 is obliquely arranged on the fixed frame 41, a motor 45 is arranged on the left side of the upper end of the slide rail 44, a first sensor 46, a second sensor 47 and a third sensor 48 are arranged on the left side of the slide rail 44 from top to bottom, a stop block 49 is arranged on the right side of the slide rail 44 near the upper end, a slider 43 is arranged on the slide rail 44, the slider 43 is connected to the motor 45 and is controlled by the motor 45, a rotating shaft 410 and a limit block 411 are arranged on the right side of the slider 43, the limit block 411 is arranged above the rotating shaft 410, and the hopper 42 is fixed on the rotating shaft 410.

[0050] A limiting block 411 is also provided on one side surface of the hopper 42 , and a blocking bar 412 is provided on the rear side of the hopper 42 .

[0051] During use of the feeding device, the material to be fed is poured into the hopper 42. When the hopper 42 is full, the motor 45 is used to drive the slider 43 to move upward on the slide rail 44, further driving the hopper 42 to move upward. When the hopper passes through the second sensor 47 during the upward movement, the second sensor 47 will control the motor 45 to slow down the speed of pulling the hopper 42 to move upward after sensing the hopper 42. At the same time, the baffle bar 412 on the rear side of the hopper 42 will contact the baffle block 49. After the baffle bar 412 contacts the baffle block 49, the baffle block 49 will resist the baffle bar 412, so that the hopper 42 will slowly move upward and gradually turn over after passing the second sensor 47, thereby feeding the material in the hopper 42 downward. When it moves to the position of the first sensor 46, the hopper 42 stops moving upward, and at the same time, the hopper 42 also flips to the maximum angle for feeding. After the feeding is completed, the motor 45 controls the slider 43 to move downward on the slide rail 44, further driving the hopper 42 to move downward. During the movement, the hopper 42 will gradually move away from the first sensor 46. At this time, the hopper 42 flipped to the maximum angle will gradually reset until the hopper 42 reaches the position of the second sensor 47. The hopper 42 completes the reset. After the reset, the hopper 42 will continue to move downward. When the hopper 42 reaches the position of the third sensor 48, the motor stops controlling the slider 43 to move, and further returns the hopper 42 to the initial position to facilitate the next feeding, and this sequence is repeated.

[0052] The setting of the limiting block 411 can limit the hopper 42 to prevent the hopper 42 from turning over downward.

[0053] The feeding device has a reasonable structural design and can continuously and efficiently transport and add materials, thereby effectively improving production efficiency.

[0054] A weighing and turning device 80 is further provided between the feeding device 40 and the conveying device 70. The weighing and turning device 80 is provided at the end of the conveying device to receive and weigh the material, and then transfer the material into the second hopper of the feeding device. Figure 11-12 As shown, the weighing tipping device 80 includes a base 81 and a tipping bucket 82. The tipping bucket 82 is arranged above the base 81. Both sides of the tipping bucket 82 are connected to the base 81 through cylinders 83 respectively. A connecting rod 85 is arranged in front of the tipping bucket 82. Both ends of the connecting rod 85 are connected to the base 81 through connecting rods 84. A weighing meter 87 is arranged at the bottom of the tipping bucket 82.

[0055] The base 81 is symmetrically provided with forward-flipping limit blocks 86 on both sides.

[0056] When the weighing and turning device 80 is working, it is arranged below the end of the conveying device 70. The workpieces fall into the tipping bucket and are weighed by the weighing meter to accurately control the quantity of each batch of workpieces. The tipping bucket is rotated around the connecting rod under the pushing action of the cylinder piston rod to convey the workpieces in the tipping bucket to the feeding device 40.

[0057] like Figure 13-14 As shown, the loading device 60 includes a foundation 61, a fixed base frame 62 and a trolley 66. The foundation 61 is provided with a groove, and the fixed base frame 62 is fixedly arranged in the groove on the foundation 61. A multi-link lifting frame 610 is provided on the fixed base frame 62. A fifth cylinder 67 is provided on the front side of the multi-link lifting frame 610 and the lifting is controlled by the fifth cylinder 67. The fifth cylinder 67 is fixedly arranged on the fixed base frame 62. A trolley placing platform 64 is fixedly arranged on the upper end of the multi-link lifting frame 610. A sixth cylinder 63 is provided at the bottom of the trolley placing platform 64 and the flipping is controlled by the sixth cylinder 63. The sixth cylinder 63 is fixedly arranged on the multi-link lifting frame 610, and the trolley 66 is fixedly placed on the trolley placing platform 64.

[0058] A hand handle 68 is connected to the rear end of the trolley 66 , and a material discharge port 69 is disposed at the front end of the trolley 66 .

[0059] The left side, right side and front side of the trolley placement platform 64 are all provided with retaining edges 65 .

[0060] During use of the feeding device 60, the multi-link lifting frame 610 is pulled downward by the fifth cylinder 67, thereby driving the trolley placement platform 64 to move downward until the trolley placement platform 64 and the foundation 61 are kept on the same plane, and then the trolley 66 filled with materials is pushed onto the trolley placement platform 64, and then the multi-link lifting frame 610 is pushed upward by the fifth cylinder 67 to further drive the trolley placement platform 64 and the trolley 66 to move upward. After reaching the designated position, the fifth cylinder 67 stops pushing, and at the same time the sixth cylinder 63 pushes, so that the trolley placement platform 64 flips upward, and further drives the trolley 66 to flip, so that the material in the trolley 66 is poured along the pouring port 69 of the trolley 66, thereby completing the loading; after the loading is completed, the sixth cylinder 63 pulls back to reset the trolley placement platform 64, and the fifth cylinder 67 pulls back to make the trolley placement platform 64 and the foundation in the same plane, thereby repeatedly loading.

[0061] The provision of the retaining edge 65 can facilitate limiting the trolley 66 on the trolley placement platform 64 during material loading.

[0062] The feeding device 60 has a reasonable structural design and is easy to use. It can simply and efficiently feed materials, reduce labor, and improve feeding efficiency.

[0063] The automatic Dacromet coating production line of the present invention has an ingenious structure and a high degree of automation. The workpiece to be processed is first put into the hopper of the hopper pushing device through the feeding device. After the workpiece falls into the basket net below the hopper through the hopper, the gripping mechanism grabs the basket net and sends it to the supporting position on the dip coating centrifugal support frame under the action of the rodless cylinder. After the loading of the dip coating centrifugal support frame is completed, the Dacromet coating tank rises to soak the workpiece in the basket net. After the dip coating is completed, the Dacromet coating tank drops a little to allow the coating liquid to leave the bottom of the basket net but still keep the basket net in the Dacromet coating tank. Then the dip coating centrifugal support frame is driven by a motor to rotate for centrifugation. After the centrifugation is completed, the Dacromet coating tank drops to below the bottom of the basket net, and the gripping mechanism on the hopper pushing device grabs the processed basket net and sends it back to the support. Then, the rotating shaft between the basket net and the support is flipped to pour the processed workpiece onto the workpiece conveyor belt below. The empty basket net can be fed again, which is cyclically used, has strong practicality, and is worthy of promotion.

[0064] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
