Description

Technical Field

[0001] The invention relates to the technical field of vacuum coating, and in particular to a high-efficiency vacuum galvanizing device with uniform heating. Background Art

[0002] Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metal, alloy or other materials for aesthetics and rust prevention. In order to ensure the adhesion of the film on the workpiece during galvanizing, the workpiece needs to be heated. Heating can increase the atomic activity on the surface of the workpiece. When the atoms or molecules of the coating material are deposited on the surface of the workpiece, they can better combine with each other, so that the coating is more firmly attached to the workpiece and the coating peeling is reduced.

[0003] The existing vacuum galvanizing equipment is found to have poor heating effect on the workpiece during use, and the hot air cannot be blown evenly on the workpiece, resulting in uneven heating of the workpiece. In addition, the existing vacuum galvanizing equipment is found to have no function of heat recovery when heating the workpiece, so there will be more heat loss during the heating process, so it needs to be improved;

[0058] Among them, in order to achieve the purpose of increasing the stability between the bracket 12 and the coating table 11, the present device is implemented by the following technical solutions: the fixing component includes a cavity 1 55 and a cavity 2 56, both of which are arranged on the coating table 11, and the cavity 2 56 is located at the bottom of the cavity 1 55, and a connecting block 57 is fixedly connected to the bottom of the bracket 12, and the connecting block 57 passes through the cavity 1 55 and extends to the inside of the cavity 2 56, and slots are arranged on both sides of the connecting block 57, and a base block 58 is fixedly connected to the bottom of the cavity 2 56, and the base block 58 is in contact with the bottom of the connecting block 57, and a threaded rod 59 is connected to the rear side of the base block 58, and the rear end of the threaded rod 59 extends to the outside of the rear side of the coating table 11, and a third gear 60 is fixedly sleeved on the outside of the rear end of the threaded rod 59, and the threaded rod 59 A threaded block 61 is sleeved on the outside, and the threaded block 61 is connected to the threaded rod 59 by threads.

[0060] Among them, in order to achieve the purpose of reducing wear, the present device adopts the following technical solution: the reciprocating screw 9 is connected to the support block 8 through a bearing, the rotating shaft 19 is connected to the cross plate 3 through a bearing, and the rotating shaft 21 is connected to the movable plate 5 through a bearing. The bearing connection can reduce wear.

[0061] The use process of the present invention is as follows: hang the workpieces that need to be galvanized on the hooks on the three brackets 12, and then control the four electric push rods 4 to work, so that the movable plate 5 can be moved downward, so that the shell 1 6, the shell 2 7 and the components on the movable plate 5 can be moved downward, so that the shell 1 6 can cover the outside of the leftmost bracket 12, and then control the heat pump 13 to work, so that the hot air can enter the hollow cylinder 14 through the pipe 1 16, and then enter the two arc shells 15, so that the hot air can be blown onto the workpiece through the through holes on the arc shell 15, and then control the motor 47 to rotate forward, and the motor 47 rotates forward to drive the rotating shaft 3 48 to rotate. Due to the sleeve 49 and the bevel gear 1 5 2 are connected to the rotating shaft three 48 through a one-way bearing, so when the motor 47 rotates forward, the bevel gear one 52 rotates, and the sleeve 49 does not rotate. The rotation of the bevel gear one 52 drives the bevel gear two 53 to rotate, and the rotation of the bevel gear two 53 drives the rotating shaft one 19, the prism 20 and the rotating shaft two 21 to rotate. The rotation of the rotating shaft two 21 drives the first gear 22 to rotate, and the rotation of the first gear 22 drives the second gear 23 to rotate. The rotation of the second gear 23 drives the hollow cylinder 14 and the two arc-shaped shells 15 to rotate, thereby changing the position of the through hole inside the shell one 6, so that the direction of the hot air blowing out can be continuously changed, so that the hot air can be evenly blown on the workpiece, thereby ensuring that the workpiece is heated evenly;

[0062] When the heat pump 13 is working, the outside air enters the heat pump 13 through the second pipe 17. In addition, a return pipe 18 is arranged between the second pipe 17 and the shell 1 6. In this way, when the shell 1 6 is charged with air, the hot air in the shell 1 6 can return to the heat pump 13 through the return pipe 18 and the second pipe 17, and then return to the shell 1 6 after being reheated. In this way, the circulation of hot air can be realized.

[0063] After the heating of the workpiece is completed, the electronic switch valve 1 30 and the electronic switch valve 2 32 are opened, the electronic switch valve 3 34 is closed, and then the fan 27 is controlled to work, and then the hot air in the shell 1 6 can be drawn into the shell 24 under the action of the pipeline 4 31, the pipeline 3 29 and the square tube 28, and then the heat storage body in the shell 24 can absorb the heat in the hot air, thereby realizing heat recovery, and after the heating is completed, the hot air remaining in the shell 1 6 can be prevented from being dissipated into the air, thereby preventing the loss of heat;

[0064] Then, the four electric push rods 4 are controlled to work so that the moving plate 5, the shell 1 6 and the shell 2 7 and other components move upward and reset, and then the motor 47 is controlled to reverse, so that the sleeve 49 rotates, and the bevel gear 1 52 does not rotate. The sleeve 49 rotates to drive the chain 51 to rotate, and the chain 51 rotates to drive the reciprocating screw 9 to rotate. The reciprocating screw 9 rotates to drive the sliding seat 10 to move to the left first, so that the coating table 11 can move to the left, and then the middle bracket 12 moves to the right below the shell 1 6, and the left side moves to the bottom of the shell 2 7, and then the zinc material is placed on the two placement racks 42, and then the electric push rods 4 are controlled to move the moving plate 5 downward, so that the shell 1 6 covers the outside of the middle bracket 12, and the shell 2 7 covers the outside of the left bracket 12;

[0065] Then, the workpiece on the middle bracket 12 is heated by the same principle. While heating, the electronic switch valve three 34 is opened, the electronic switch valve one 30 and the electronic switch valve two 32 are closed, and the fan blades in the fan 27 are controlled to reverse. In this way, the outside air can be drawn into the pipe two 17 under the action of the square tube 28 and the pipe five 33, and then enter the shell one 6 through the heat pump 13. When the fan 27 works to draw the outside air into the pipe two 17, the air will pass through the shell, and then the air will contact the heat storage body. Since the heat storage body absorbs heat, the air will be heated when passing through, thereby realizing the secondary utilization of heat.

[0066] While heating, the vacuum pump 43 is controlled to work, so that the interior of the housing 7 can be evacuated to a vacuum, and then the two electron beam generators 44 are controlled to work, so that the electron beam can be irradiated on the zinc material, thereby heating the zinc material at a high temperature, and then heating the zinc material in a vacuum environment will cause it to sublime, and then adhere to the workpiece, thereby achieving galvanizing;

[0067] When the heating and galvanizing work is finished, the electric push rod 4 is controlled to move the movable plate 5 upward to reset, and then the motor 47 is controlled to reverse again, so that the coating table 11 can move to the left again, and then the workpiece on the right bracket 12 is heated and the workpiece on the middle bracket 12 is galvanized by the same principle until the workpieces on the three brackets 12 are galvanized, wherein the galvanizing work can be performed alone when the workpiece on the right bracket 12 is galvanized, and the heating work can be omitted;

[0068] When the motor 47 is reversed to move the coating table 11 to the left, the three third gears 60 will mesh with the toothed plate 36, so that the third gear 60 will rotate during the meshing, thereby driving the threaded rod 59 to rotate, and the rotation of the threaded rod 59 drives the threaded block 61 to move forward, thereby moving the two protrusions 65 forward. Since the protrusions 65 are embedded in the spiral grooves 64, the two protrusions 65 can rotate the two rotating rods 62 when they move forward, and the rotation of the two rotating rods 62 can move the two clamping blocks 63 out of the clamping grooves, thereby releasing the fixation of the connecting block 57, and then the bracket 12 on the coating table 11 can be manually removed, and then a new bracket 12 can be placed, and when placing it, the connecting block 57 on the bracket 12 can be inserted into the cavity 1 55 and the cavity 2 56;

[0069] When the workpieces on the three brackets 12 are all coated and the three brackets 12 are replaced, the control motor 47 continues to reverse, so that the coating table 11 can move to the right and reset. When moving to the right, the three third gears 60 will mesh with the tooth plate 36 again, so that the threaded rod 59 reverses, the threaded block 61 and the protrusion 65 move backward, and then the two rotating rods 62 reverse, so that the two clamping blocks 63 can be clamped in the clamping groove again, thereby achieving the fixation of the connecting block 57, thereby fixing the bracket 12, so that the stability between the bracket 12 and the coating table 11 can be increased, and after moving to the right side, the workpieces are hung again on the three new brackets 12, and then the heating and galvanizing work is continued in the same principle;

[0070] The chassis on the bracket 12 is made of rubber material, which can ensure a certain degree of sealing when in contact with the shell 1 6 and the shell 2 7. The heat storage body used in this device is made of ceramic material, which can ensure the heat storage effect. The fan 27 used is model 200FZY2-D.

[0071] 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.
