[0020] The use process of the present invention is as follows: the vaporized zinc powder is introduced into the material pipe 7, and then the zinc powder enters into two pipes 18 through two hoses 20, and finally can be sprayed out through multiple nozzles 19, and then the heat pump 10 is controlled to work when the vaporized zinc powder is introduced into the material pipe 7, and then the hot air can enter the shell 8 through the pipe 11. Since the shell 8 is sleeved on the outside of the material pipe 7, the material pipe 7 can be heated, and then the temperature of the material pipe 7 is increased, so that the effect of heating and heat preservation can be achieved, so that the temperature of the gaseous zinc atoms will not drop when flowing in the material pipe 7, and the state of the zinc powder vaporization can be maintained. In addition, the spiral strip 9 is designed, so that the hot air flows in a spiral shape around the material pipe 7 when flowing in the shell 8, so that the heating effect on the material pipe 7 is better and the heat preservation effect on the zinc powder is better; When the vaporized zinc powder is sprayed out from the nozzle 19, the workpiece is placed on the belt conveyor 3, and then the belt conveyor 3 is controlled to work to convey the workpiece to the left, so that the workpiece can be close to the two pipes 4 18, and at the same time the motor 27 is controlled to work, the motor 27 drives the reciprocating screw 28 to rotate, the reciprocating screw 28 rotates and drives the sliding seat 29 to move left and right, the sliding seat 29 moves left and right and drives the limit block 32 to move left and right, when the limit block 32 moves to the right, it can push the push rod 1 35 and the piston 1 34 to move to the right, and at the same time the spring 36 is compressed, and when the piston 1 34 moves to the right, the air in the box 1 33 will enter the box 2 37 under the action of the connecting pipe 40, and then the piston 2 3 8 and the push rod 2 39 will move to the right, thereby making the moving block 44 and the tooth plate 43 move to the right, and the tooth plate 43 moving to the right can make the front gear 1 42 rotate, and the rotation of the front gear 1 42 drives the rear gear 1 42 to rotate, so that the two gears 1 42 can rotate at the same time, and the rotation of the two gears 1 42 drives the two pipes 4 18 to rotate, and the rotation trajectories of the two pipes 4 18 are both half an arc, so that when the workpiece moves to the left and approaches the two pipes 4 18, the two pipes 4 18 can open and merge, so that the workpiece can not only pass smoothly between the two pipes 4 18, but also ensure that the zinc powder is evenly sprayed on the workpiece, so that the quality of the coating can be guaranteed; When the sliding seat 29 moves to the left, the spring 36 will rebound, so that the piston 1 34, the push rod 1 35, the piston 2 38, the push rod 2 39, the tooth plate 43 and other components can be reset, and then the two gears 1 42 are reversed, so that the two pipes 1 11 can be reset, so that the two pipes 4 18 can be continuously opened and merged. At this time, it is only necessary to manually put the workpiece on the belt conveyor 3 regularly to continuously carry out the galvanizing work; The galvanized workpiece will be further conveyed to the left by the belt conveyor 3, so that it will pass through the shell 5 and pass between the two square tubes 14. In addition, a pipe 3 17 is designed so that the hot air in the shell 8 will enter the hollow shell 12, and then enter the two square tubes 14 through the two pipes 2 16, and then blow on the workpiece through multiple through holes, so that the zinc plating can be dried and solidified, which can enhance the adhesion between the zinc plating layer and the base material. The sliding seat 29 moves left and right and can also make the convex rod 30 move left and right. Since the convex rod 30 passes through the through groove, the convex rod 30 can make the lever 31 swing back and forth when it moves, so that the hollow shell 12 rotates back and forth continuously, and the back and forth rotation of the hollow shell 12 drives the connecting plate 13 and the two square tubes 14 to rotate back and forth, so that the hot air can be blown evenly on the workpiece, thereby ensuring the drying and curing effect. In addition, the left and right movement stroke of the sliding seat 29 is limited, so the rotation range of the hollow shell 12, the connecting plate 13 and the two square tubes 14 is also limited, and the square tube 14 will not affect the movement of the workpiece.

[0021] Refer to the attached Fig.10 The present invention also provides a vacuum galvanizing control system, including a central processing unit 46, an HMI control terminal 47, a speed measurement module 48, an alarm module 49 and an inertia correction coefficient input module 50, wherein the central processing unit 46 is electrically connected to the motor 27 and the belt conveyor 3, the HMI control terminal 47 and the inertia correction coefficient input module 50 are both electrically connected to the input terminal of the central processing unit 46, the speed measurement module 48 is electrically connected to the input terminal of the alarm module 49, and the alarm module 49 is electrically connected to the input terminal of the central processing unit 46; During galvanizing, the central processor 46 can be used to control the motor 27 and the belt conveyor 3 to work. An HMI control terminal 47 is designed. A numerical value is input on the HMI control terminal 47, and then the belt conveyor 3 can convey the workpiece at the input numerical value as the conveying speed. Due to the load on the belt conveyor 3, the actual conveying speed of the belt conveyor 3 may not reach the input numerical value. At this time, the speed measurement module 48 can be used to test the moving speed of the workpiece to determine whether it meets the standard. If it does not meet the standard, the warning module 49 will alarm and feed back the result to the central processor 46. Then the staff can modify the inertia correction coefficient through the inertia correction coefficient input module 50. After the modification is completed, the speed is measured to see whether the actual conveying speed is the same as the ideal one. If it is not the same, the inertia correction coefficient is continuously modified until the two speeds are consistent. In this way, when the actual conveying speed is inconsistent with the ideal speed, there is no need to adjust the transmission mechanism in the belt conveyor 3.

[0022] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the above technical solutions or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention belongs to the scope of protection claimed by the present invention.
