[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Example 1

[0022] Reference Figure 1, shows a schematic structural diagram of an embodiment of a surface treatment device of the present invention, which may specifically include: a conveying circuit 1, a preheating furnace 2, a spraying mechanism 3, a polishing mechanism 4 and a base 5. It should be noted that the conveying circuit 1 is a circulating circuit formed by the contact of two U-shaped openings. The conveying circuit 1 is moved by a transmission mechanism. A certain point on the conveying circuit 1 is used as a reference point, and the corresponding position on the base 5 is used as a reference position. After waiting for a certain period of time, the reference point can move from this position through the conveying circuit 1 and return to this position. The preheating furnace 2 is used to heat the workpiece to reach a preset temperature, and the spraying mechanism 3 is used to spray the material to be sprayed onto the workpiece. The above process is to pass the workpiece through the preheating furnace 2, the spraying mechanism 3 and the polishing mechanism 4 in sequence through the conveying circuit 1.

[0023] Furthermore, the conveying loop 1 is laid on the base 5; one end of the conveying loop 1 passes through the preheating furnace 2; the spraying mechanism 3 is arranged at a position adjacent to the discharge port of the preheating furnace 2 and on both sides of the conveying loop 1; the polishing mechanism 4 is arranged at a position adjacent to the discharge end of the spraying mechanism 3 and on both sides of the conveying loop 1. It should be noted that, taking the clockwise movement of the conveying loop 1 as an example, one end of the conveying loop 1 passes through the preheating furnace 2, that is, the conveying loop 1 enters the inlet of the preheating furnace 2 and is transported out from the discharge port of the preheating furnace 2, and the workpiece needs to be pre-set at a preset distance from the inlet of the preheating furnace 2 and at a position on the conveying loop, so that after the workpiece is placed on the conveying loop 1, it can move clockwise and pass through the inlet of the preheating furnace 2 to enter the preheating furnace 2, and be transported out from the discharge port of the preheating furnace 2 to the next processing step. ; The spraying mechanism 3 is arranged near the discharge port of the preheating furnace 2 and is located on both sides of the conveying loop 1. It is to facilitate the workpiece transported from the discharge port of the preheating furnace 2 to move clockwise to the working area of ​​the spraying mechanism 3, and then the workpiece is sprayed. Similarly, the polishing mechanism 4 is arranged near the discharge end of the spraying mechanism 3 and is located on both sides of the conveying loop 1. It is also to facilitate the workpiece to move clockwise from the discharge end of the spraying mechanism 3 to the working area of ​​the polishing mechanism 4, and then the workpiece is polished.

[0024] It should also be noted that the conveyor loop 1 can move clockwise or counterclockwise. If it moves counterclockwise, it is necessary to ensure that the workpiece is pre-set near the inlet of the preheating furnace 2 and located on the conveyor loop 1, the spraying mechanism 3 is set near the discharge of the preheating furnace 2 and located on both sides of the conveyor loop 1, and the polishing mechanism 4 is set near the discharge end of the spraying mechanism 3 and located on both sides of the conveyor loop 1. Regardless of whether the conveyor loop 1 moves clockwise or counterclockwise, it is necessary to ensure that the workpiece can be processed from the preheating furnace 2 to the spraying mechanism 3 and then to the polishing mechanism 4.

[0025] Furthermore, the conveyor circuit 1 also includes a bracket for placing the workpiece; the bracket is fixedly connected to the conveyor circuit 1. It should be noted that the bracket is used to facilitate the placement of the workpiece. The conveyor circuit 1 preferably uses a conveyor chain as a conveying method. The bracket is fixed to the conveyor chain, and the workpiece is placed on the bracket. When the conveyor chain moves, the workpiece is driven to move.

[0026] Furthermore, the surface treatment device further includes a rotating tray fixedly connected to the bracket. It should be noted that the rotating tray is enabled to rotate by a self-rotating mechanism, with the motor and drive shaft connected by a coupling. The drive shaft utilizes two sets of bevel gears to drive the workstation shaft, which in turn drives the rotating tray.

[0027] Example 2

[0028] Reference Figure 1 The schematic diagram of the structure of an embodiment of a surface treatment device of the present invention is shown. The preheating furnace 2 further includes an air heating box 6 and a preheating circulation fan 7. It should be noted that the preheating furnace 2 acts as a reaction vessel. The workpiece is heated within the preheating furnace 2. The air heating box 6 performs the heating function. The preheating circulation fan 7 provides circulating air. This circulating air enters the air heating box and then enters the preheating furnace 2 as heated circulating air, thereby preheating the workpiece.

[0029] Furthermore, the air heating box 6 is arranged at the top of the preheating furnace 2 and is communicated with the preheating furnace 2; the preheating circulation fan 7 is arranged at the top of the preheating furnace 2; the air outlet of the preheating circulation fan 7 is connected to the air heating box 6. It should be noted that the preheating furnace 2 adopts a double-layer structure. It is more preferred that the inner layer material is 1.5tSUS304L stainless steel plate and the outer layer material is 1.5tA3 steel plate. In order to keep warm, the middle of the double layer of the preheating furnace 2 is filled with insulation material. It is more preferred to use 100mm rock wool. The air heating box 6 is heated by heating wire. It is more preferred to use barbed stainless steel heating tubes with a power of 2.5KW and a number of 15. The total heating power can reach 37.5KW, and the working voltage is 380V, ensuring that the temperature of the workpiece is maintained above 50°C when it goes out of the discharge port. The preheating circulation fan 7 is more preferably a split circulation fan, which can achieve an air flow of 1455~2620m 3 / h.

[0030] Further, combined Figure 2 and Figure 3 , showing the front view and right view of an embodiment of a surface treatment device of the present invention, the spraying mechanism 3 further includes an air blowing head, a spray gun, a first pipe, a second pipe, an air compressor, and a stirring mechanism; the opening direction of the air blowing head and the spray gun is set to face the conveying circuit; the spray gun and the stirring mechanism are connected by a first pipe; the air blowing head and the air compressor are connected by a second pipe. It should be noted that the air compressor is a blowing medium, compressed air. During spraying, compressed air plays an important role in the transportation and atomization of the paint. Since the compressed air and the paint are in direct contact, the quality of the compressed air source directly affects the final coating quality. It is preferably filtered by a 0.2uM CKD air filter and controlled by a CKD solenoid valve. The material to be sprayed is added to the stirring mechanism for molybdenum treatment of the workpiece surface. Liquid molybdenum is added to the stirring mechanism. The workpiece automatically rotates at different workstations, at which time it should have entered the working range of the spraying mechanism 3. Then, the air blowing head and the spray gun automatically blow and spray up and down.

[0031] Furthermore, the surface treatment device also includes an exhaust gas treatment device 8 for collecting exhaust gas; the exhaust gas treatment device 8 is disposed on the base 5; the exhaust gas treatment device 8 has multiple gas collection ports, which are respectively disposed toward the preheating furnace 2, the spraying mechanism 6, and the polishing mechanism 7. It should be noted that the exhaust gas generated during the processing steps of the surface treatment device is prevented from causing air pollution.

[0032] Furthermore, the polishing mechanism 4 uses brushes for polishing, and two sets of horsehair brushes are more preferred. The workpiece reaches the working range of the polishing mechanism 4 along the conveying loop 1, the workpiece rotates, and the two brushes rotate automatically for polishing. The position interval between the two brushes can be adjusted to a random size. The adjustment method is a hand-cranked screw and guide rod structure, and the brush drive uses a speed-regulating motor.

[0033] Furthermore, the surface treatment device also includes a tensioning mechanism. The conveying chain of the conveying loop 1 needs to be tensioned by the tensioning mechanism. The tensioning cylinder pushes the slider mechanism to drive the driven wheel sprocket group to automatically tension the conveying chain to ensure that the conveying loop 1 runs smoothly.

[0034] Furthermore, the surface treatment device also includes a limiting mechanism, which is composed of a cylinder and a linear guide rail limiting block, and is a mechanical positioning device that prevents the workpiece from being misplaced at the spraying station due to frequent starting and stopping of the chain.

[0035] Furthermore, the surface treatment device also includes an operating electrical box, which is arranged on the base 5. The operating electrical box is electrically connected to the conveying circuit 1, the rotating tray, the air heating box, the brush speed and the spraying mechanism 3 respectively, and the control of each function can be achieved by operating the operating electrical box.
