[0054] The use process of the present invention is as follows: when the workpiece needs to be dried before vacuum galvanizing, the workpiece is placed on the rubber ring 4 on the left, and then the motor 21 is controlled to rotate forward, the motor 21 rotates forward to drive the bevel gear 1 22 to rotate, the bevel gear 1 22 rotates to drive the bevel gear 2 23 to rotate, the bevel gear 2 23 rotates to drive the rotating shaft 1 16, the transmission rod 17 and the rotating shaft 2 18 to rotate, because the sleeve 1 19 is connected to the rotating shaft 2 18 through a one-way bearing, and the sleeve 2 20 is connected to the rotating shaft 16 through a one-way bearing, so when the motor 21 rotates forward, the sleeve 2 20 rotates, the sleeve 1 19 does not rotate, and the sleeve 2 20 rotates. The second chain 33 is driven to rotate, the second chain 33 rotates to drive the rotating block 2 to rotate, the rotating block 2 rotates to drive the workbench 3 to rotate, the motor 21 is controlled to rotate forward to make the workbench 3 rotate half a circle, so that the workpiece just placed can be moved to the right and located directly below the shell 9, and then the four electric push rods 7 are controlled to work, so that the moving plate 8 can move downward, so that the moving plate 8 can cover the outside of the workpiece, and then the heat pump 12 is controlled to work, so that the hot air can pass through the pipe three 13 and the pipe two 11 into the two pipes one 10, and finally blow on the surface of the workpiece through multiple air outlets, thereby drying the workpiece;

[0055] When the hot air is blown on the surface of the workpiece, the motor 21 is controlled to reverse, so that the sleeve 19 can rotate, and the sleeve 20 does not rotate. The rotation of the sleeve 19 drives the chain 131 to rotate, and the rotation of the chain 131 drives the pipe 10 and the two pipes 21 to rotate, so that the position of the air outlet can be continuously changed, so that the hot air is blown evenly on the surface of the workpiece, thereby ensuring the quality of drying. At this time, the workpiece to be dried can be placed on another rubber ring 4 manually. When the first workpiece is dried, the electric push rod 7 is controlled to work to move the moving plate 8 upward and reset, so that the shell 9 can move upward and reset, and then the motor 21 is controlled to rotate forward to make the workbench 3 rotate half a circle again, so that the second workpiece can be moved to the bottom of the shell 9, and then the same principle continues to perform the drying work, and at this time, the workpiece that has just been dried can be removed manually and a new one can be placed, so that the device can continuously perform the drying work, so that the device will not appear in a state of long-term standby when in use, which can increase the drying efficiency;

[0056] When the heat pump 12 is working, the outside air will enter the heat pump 12 through the pipe 4 14, and the device is designed with a connecting pipe 15 between the shell 9 and the pipe 4 14, so that the circulation of hot air can be realized, and the hot air blown inside the shell 9 can return to the heat pump 12 again for reheating and then blown onto the workpiece again, which can achieve the effect of saving energy;

[0057] When the workpiece is placed on the rubber ring 4, the workpiece is covered outside the outer frame 34, and when the rotating block 2 and the workbench 3 rotate to move the workpiece from the left side to the right side, the first gear 46 will move inside the gear ring 47, so that the reciprocating screw 41 can be rotated, and the rotation of the reciprocating screw 41 can move the sliding seat 42, and the movement of the sliding seat 42 can move the two moving rods 2 44, and the movement of the two moving rods 2 44 can move the two pistons 2 43, and then under the action of the two pipes 5 39, the movement of the two pistons 2 43 can make the air in the left box body 2 38 flow back and forth with the left box body 1 35, and the air in the right box body 2 38 flows back and forth with the right box body 1 35, so that when the left box body 1 35 and the box body 2 38 move from the left side to the right side, the piston 1 36 in the box body 1 35 will move upward, and when the right box body 1 35 and the box body 2 38 move from the right side to the left side, the piston 1 36 in the box body 1 35 will move downward;

[0058] When the left box body 1 35 and the box body 2 38 move from the left side to the right side, the piston 1 36 will move upward, so that the moving rod 1 37 can move upward, and the moving rod 1 37 moving upward can make the lower moving block 49 move upward, and the lower moving block 49 moving upward can make the two tooth plates 52 below move upward, and then under the action of the two second gears 51, the lower moving block 49 and the two tooth plates 52 move upward, so that the upper moving block 49 and the two tooth plates 52 move downward, so that the two moving blocks 49 will be close to each other, and when they are close, the two clamping blocks 54 can be moved outward under the action of the four pull rods 56, so that when moving from the left side to the right side, the two clamping blocks 54 can contact the inner wall of the workpiece, thereby automatically fixing the workpiece, so that the workpiece can be prevented from shifting during drying;

[0059] When the right box body 1 35 and the box body 2 38 move from the right side to the left side, the piston 1 36 will move downward, so that the moving rod 1 37 can be pulled downward, and then the distance between the two moving blocks 49 will become larger according to the opposite principle, and then the two clamping blocks 54 can be moved to the middle under the action of the four pull rods 56, so that when moving from the right side to the left side, the two clamping blocks 54 can automatically release the fixation of the workpiece, without the need for manual release, which can reduce the labor intensity of manual work.

[0060] 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.
