Abstract
A galvanized coating layer production line is disclosed. The production line comprises sequentially arranging, according to a workflow, a sand-blasting machine, a fluxing machine, a first air knife, a preheating device, a hot-dip bath, a second air knife, and a cooling chamber. The fluxing machine, the first air knife, the preheating device, the hot-dip bath, and the second air knife are each provided with a moving passageway through which a workpiece may pass; and disposed between the apparatus are rolling conveyors along which workpieces move. Rebar is able to lie flat as it moves one-by-one between the apparatus during the process. This allows for highly efficient production and for the electroplating of long rebar. The production line is easy both to expand and to improve.

It is operated by a suspension crane (or an electric hoist operated by hand) to hang workpieces (such as rebars). Because this conventional production line uses an electric hoist or a trolley conveyer to hang workpieces, the length of the workpieces to be electroplated is limited. For large-sized workpieces, the depth of the galvanising tank must be deep. As a result, the equipment is large in size, and the production efficiency is low. - Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
- The primary object of the present invention is to provide a galvanized coating layer production line. The production efficiency is high. The electroplated rebars can be long.
- In order to achieve the aforesaid object, the galvanized coating layer production line comprises a sand-blasting machine, a fluxing machine, a first air knife, a preheating device, a hot-dip bath, a second air knife, and a cooling chamber which are arranged sequentially according to a workflow. The fluxing machine, the first air knife, the preheating device, the hot-dip bath, and the second air knife are each provided with a moving passageway through which a workpiece can pass. Between the devices is provided with a rolling conveyer on which the workpiece run.
- Preferably, the fluxing machine includes upper and lower rows of fluxing heads, and between the upper and lower rows of fluxing heads is the moving passageway for the workpiece to pass through the fluxing machine
- Preferably, the first air knife and the second air knife have an identical structure. The first air knife comprises a triangular frame. An air wall of the triangular frame is provided with a plurality of air nozzles. A middle portion of the triangular frame is defined as the moving passageway for the workpiece to pass through the first air knife.
- Preferably, the preheating device comprises a support, a guide pipe, and a heating wire. The guide pipe is installed on the support. The support is fixed on the ground. The heating wire is wound on the guide pipe. The guide pipe is provided with a plurality of guide holes. The guide holes are the moving passageway for the workpiece to pass through the preheating device.
- Preferably, the hot-dip bath comprises a big bath, a small bath, and an electroplating solution circulatory system. The small bath is placed in the big bath. An upper portion of the small bath is beyond a top of the big bath. Two opposing walls of the small bath, beyond the big bath, are formed with through holes respectively. The through holes of the two opposing walls of the small bath are disposed at an axis. The through holes of the two opposing walls of the small bath are the moving passageway for the workpiece to pass through the hot-dip bath.
- Preferably, between the sand-blasting machine and the fluxing machine, between the first air knife and the preheating device, between the preheating device and the hot-dip bath, between the second air knife and the cooling chamber is provided with the rolling conveyer on which the workpiece run.
- As the fluxing machine, the first air knife, the preheating device, the hot-dip bath, and the second air knife are provided with the moving passageways through which workpieces can pass, rebars can lie flat and pass one-by-one through the devices in the order of workflow. The production efficiency is high, the electroplated rebars are long, and each device can be added or removed according to coating requirements. The production line is structurally compact, highly modular, and extension or improvement thereof is simple.
