FIG. 6 , the coolingchamber 9 comprises anupper lid 91, awater tank 92, a plurality of shower heads 93, and awater inlet pipe 94. Thewater inlet pipe 94 is connected with a water source. Theupper lid 91 is to cover the shower heads 93. Thewater tank 92 is installed on the ground and located under the shower heads 93. - As shown in
FIG. 1 andFIG. 7 , the working process of the present invention is that the workpieces (rebars) 30 pass through the sandblastingmachine 1, the assistingplating machine 2, thefirst air knife 3, thefirst pre-heater 4, thehot dip tank 5, thesecond air knife 6, thesecond pre-heater 7, theepoxy spray chamber 8, and thecooling chamber 9 sequentially. Finally, the processed workpieces 30 are collected on arebar collection rack 20 disposed at the tail end of the production line. Each working process is controlled by a unified control electrical box. The specific steps are as follows: - 1. the workpieces 30 pass through the sandblasting
machine 1 for removing oil and dust; - 2. the workpieces 30 pass through the assisting
plating machine 2 and thefirst air knife 3 for applying a plating assistant agent evenly and drying so that electroplating solution can be adhered to the surfaces of the workpieces 30 effectively when electroplated; - 3. the workpieces 30 pass through the
first pre-heater 4 for drying the surfaces of the workpieces 30 by heat; - 4. the workpieces 30 enter the
hot dip tank 5 from the throughhole 521 of the wall of thehot dip tank 5 for electroplating the surfaces of the workpieces 30; - 5. the workpieces 30 pass through the
second air knife 6 and thesecond pre-heater 7 for drying and solidifying the electroplating solution on the surfaces of the workpieces 30; - 6. the workpieces 30 pass through the
epoxy spray chamber 8 for spraying epoxy on the surfaces of the workpieces 30; and - 7. the workpieces 30 pass through the
cooling chamber 9 for cooling and passivating to get the finished products, and the finished products are delivered to therebar collection rack 20. - The feature of the present invention is that each device is provided with a moving channel through which the workpieces can pass. The aforesaid structure is just a preferred embodiment of the present invention. The length of the rolling conveyer can be changed according to the demand.
- Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
