[0005] The present invention provides a hot-dip galvanizing device for bolt production and a processing technology thereof, which adopts the following technical scheme: A hot-dip galvanizing device for bolt production comprises a galvanizing tank and a protective box, wherein the galvanizing tank is arranged in the protective box, the inner side wall of the protective box is hinged with a screening material guide plate, the discharge end of the screening material guide plate is above the galvanizing tank, a hoisting device is arranged outside the protective box, a galvanizing barrel is arranged at the end of the hoisting device, the galvanizing barrel is located in the galvanizing tank, a stirring piece is rotatably arranged in the galvanizing barrel, a driving rod is fixedly arranged on the inner bottom wall of the galvanizing tank, and the upper end of the driving rod is movably plugged into the bottom of the stirring piece.

[0006] Through the above technical scheme, the galvanizing barrel is first hoisted into the protective box by the hoisting equipment, and then the debris on the surface of the bolt is screened by the screening guide plate, and the bolt is transported to the galvanizing barrel at the same time, and then the galvanizing barrel is sunk into the immersion plating tank by the hoisting equipment for galvanizing.

[0007] Optionally, in the above-mentioned hot-dip galvanizing device for bolt production, a through hole for the galvanizing barrel to pass through is opened on the top surface of the protective box, and a feed pipe is fixedly inserted on the top surface of the protective box.

[0010] Through the above technical solution, when the bolt falls into the screening guide plate, the bolt is guided through the trapezoidal guide groove, and at the same time, the debris on the surface of the bolt falls into the collection box through the screening hole.

[0011] Optionally, in the above-mentioned hot-dip galvanizing device for bolt production, a first motor is provided on the side wall of the protection box, a rotating shaft of the first motor passes through the protection box and is fixedly provided with a cam, and an outer wall of the cam is slidably matched with the bottom of the collection box.

[0012] Through the above technical solution, the first motor is used to drive the cam to rotate, and as the cam rotates, the collecting box and the screening guide plate are controlled to vibrate, thereby shaking off the debris on the surface of the bolt.

As the screening guide plate vibrates, the bolt continuously rolls down and rolls into the galvanized barrel; S103: The galvanizing barrel is pushed by an electric push rod to move into the immersion bath to galvanize the bolts. As the galvanizing barrel moves downward, the driving rod is inserted into the stirring member, thereby causing the stirring member to rotate to stir the bolts in the galvanizing barrel. S104: When the galvanizing of the bolt is completed, the galvanizing barrel is pulled upward by the electric push rod, and the stirring member is separated from the driving rod, and then the support plate, the clamping plate and the galvanizing barrel are driven to rotate by the second motor, so that the excess zinc liquid on the surface of the bolt is thrown out, thereby reducing the possibility of zinc liquid waste; S105: The galvanized barrel is pulled to the outside of the protective box by an electric push rod, and finally the galvanized barrel is moved to the unloading area by a walking frame. Then, the clamping plate is pushed to move and separate from the galvanized barrel by a double-headed push rod, thereby realizing the disassembly of the galvanized barrel, and a new galvanized barrel is installed between the two clamping plates to repeat a new round of galvanizing process.

[0020] In summary, the present invention includes at least one of the following beneficial effects: The galvanizing barrel is sunk into the immersion bath by means of a lifting device. As the galvanizing barrel moves downward, the driving rod is inserted into the stirring piece, which causes the stirring piece to rotate and stir the bolts, thereby reducing the possibility that the parts where the bolts are fitted together are difficult to galvanize, so the galvanizing effect of the bolts is better; The first motor is used to drive the cam to rotate. As the cam rotates, the collecting box and the screening guide plate are controlled to vibrate, thereby shaking off debris on the surface of the bolt and causing the debris to fall into the collecting box through the screening holes, thereby reducing the possibility that debris attached to the bolt surface will affect the galvanizing of the bolt.
