Hot-dip galvanizing is to first pickle the steel parts to remove the iron oxide on the surface of the steel parts. After pickling, they are cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 A hot-dip galvanizing device for drywall nails comprises a galvanizing tank 1, the galvanizing tank 1 contains hot-dip galvanizing solution, a heating cylinder 2 is arranged on the upper side of the galvanizing tank 1, a motor 3 is fixedly installed on the upper end of the heating cylinder 2, brackets 5 are fixedly installed on both sides of the heating cylinder 2, a column 4 is fixedly installed on the galvanizing tank 1, a lower rotating ring 10 is rotatably installed on the lower side of the column 4, an upper rotating ring 12 is rotatably installed on the upper side of the column 4, the output end of the motor 3 rotates through the inner side of the heating cylinder 2 and is fixedly connected to the upper rotating ring 12, a sliding rod 11 is fixedly installed between the upper rotating ring 12 and the lower rotating ring 10, the lower end of the heating cylinder 2 is open, and a placing mechanism is sleeved on the sliding rod 11. The positioning mechanism includes a sliding cylinder 13 and an annular groove 15. The sliding cylinder 13 is slidably installed on the column 4 and a through hole 14 matching the sliding rod 11 is opened on the sliding cylinder 13. The sliding rod 11 slides through the through hole 14. Four suspension rods 17 are evenly installed on the lower side of the sliding cylinder 13. An inner ring seat 18 is fixedly installed at the lower end of the suspension rod 17. An outer ring seat 19 is arranged on the outer side of the inner ring seat 18. A filter plate 20 is fixedly connected between the inner ring seat 18 and the outer ring seat 19. The outer diameter of the outer ring seat 19 is slightly smaller than the inner diameter of the galvanizing tank 1 and the heating cylinder 2. The annular groove 15 is fixedly installed on the outer side of the sliding cylinder 13 and a lifting mechanism is clamped on the side of the annular groove 15.

[0024] Through the above structure, the starting motor 3 can drive the upper swivel 12 to rotate. The upper swivel 12 and the column 4 are in a rotational relationship. The column 4 is fixedly installed on the galvanizing tank 1. Therefore, when the upper swivel 12 rotates, the column 4 will not rotate. The upper swivel 12 drives the sliding rod 11 which is in a fixed connection with it to rotate synchronously. The sliding rod 11 drives the lower swivel 10 fixed at the bottom of the sliding rod 11 to rotate. The lower swivel 10 and the column 4 are also in a rotational connection relationship. When the sliding rod 11 rotates, it will drive the sliding cylinder 13 through which its middle part slides to rotate. Here, the sliding cylinder 13 and the column 4 are in a sliding connection relationship. Then, the sliding cylinder 13 can maintain relative rotation while having a sliding relationship with the column 4 driven by the motor 3.

[0025] In this embodiment, a heating wire is arranged inside the heating tube 2 .

[0026] Through the above structure, the heating tube 2 heats the drywall screws by increasing the internal temperature through the electric heating wire. The heating of the electric heating wire has the advantages of precise temperature control and uniform heating, which ensures uniform heating of the drywall screws.

[0027] In this embodiment, the lifting mechanism includes an electric telescopic rod 8, a cross bar 9 and a snap-in tooth 16. The electric telescopic rod 8 is symmetrically distributed on both sides of the galvanizing tank 1. The cross bar 9 is fixedly installed on the upper end of the electric telescopic rod 8. The snap-in tooth 16 is fixedly installed on the side end of the cross bar 9 and the snap-in tooth 16 is snap-engaged and slid with the annular groove 15. A second slide groove 7 is opened on the inner side of the bracket 5, and a first slide groove 6 is opened on the side wall of the heating cylinder 2. The first slide groove 6 and the second slide groove 7 are both in sliding contact with the cross bar 9.

[0028] Through the above structure, when the electric telescopic rod 8 is started to rise, it drives the cross bar 9, and the cross bar 9 drives the engaging teeth 16, so that the engaging teeth 16 drive the annular groove 15 to move upward, and the sliding cylinder 13 and the filter plate 20 installed below rise synchronously. During this process, if the motor 3 is started to drive the sliding cylinder 13 to rotate, the annular groove 15 is driven to rotate by the sliding cylinder 13. Due to the engaging and sliding relationship between the engaging teeth 16 and the annular groove 15, when the engaging teeth 16 lift or lower the annular groove 15, its rotation does not interfere with its rise or fall.

[0029] In this embodiment, four slide bars 11 are provided and the slide bars 11 are evenly distributed on the outer side of the column 4 .

[0030] Through the above structure, the outer side of the slide rod 11 column 4 is evenly distributed in a circular pattern, which strengthens the overall connection strength between the upper swivel 12, the slide rod 11 and the lower swivel 10, that is, improves the stable guiding effect of the slide rod 11 on the sliding cylinder 13.

[0031] In the utility model, when in use, the dry wall nails are placed on the filter plate 20, the motor 3 and the electric telescopic rod 8 are started synchronously, and the electric heating wire in the heating cylinder 2 is started to heat the heating cylinder 2 to a suitable temperature. The electric telescopic rod 8 is started to drive the sliding cylinder 13 and the filter plate 20 installed on the lower side thereof to rise to the inner side of the heating cylinder 2. At this time, under the rotation of the motor 3, the filter plate 20 and the dry wall nails placed thereon are driven to rotate inside the heating cylinder 2, so that the dry wall nails are heated more evenly. After the heating is completed, the electric telescopic rod 8 is started to drive the filter plate 20 and the dry wall nails placed thereon to descend and be immersed in the hot-dip galvanizing solution. The filter plate 20 is rotated in the hot-dip galvanizing solution, and the hot-dip galvanizing solution forms an eddy current around the drywall nails through rotation. The hot-dip galvanizing solution has a certain fluidity relative to the drywall nails, which increases the flow contact with the surface of the drywall nails, making the galvanized layer formed on the surface of the drywall nails more uniform, further enhancing the production quality of hot-dip galvanizing of the drywall nails. After the galvanizing is completed, the motor 3 stops rotating, and the electric telescopic rod 8 drives the filter plate 20 to rise above the galvanizing tank 1, without manual scooping, and the drywall nails will not fall into the galvanizing tank 1, which is easy to use and highly practical.
