[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0021] See also Figures 1 to 2 The embodiment of the utility model provides a powder spraying device for processing the charging pile shell, which includes: a chain conveyor belt 1, a conveying rod 2, a processing and fixing mechanism, a powder spraying preheating mechanism, an airflow surrounding mechanism and a powder spraying chamber.

[0022] Please refer to Figure 1 As shown, the chain conveyor 1 is fixedly connected with a plurality of evenly distributed conveying rods 2, so that continuous conveying of workpieces can be realized and production efficiency can be improved. The bottom end of the conveying rod 2 is connected with a processing fixing mechanism for fixing the workpiece, and the processing fixing mechanism includes a top plate 3, a bottom plate 8, a vertical rod 6, a slider 5, a clamping plate 7 and a spring 4. The bottom end of the conveying rod 2 is fixedly connected with the top plate 3, and the bottom end of the top plate 3 is fixedly connected with the bottom plate 8 through the vertical rod 6, and the outer surface of the vertical rod 6 is slidably connected with two sliders 5, and two springs 4 are strung on the outer side of the vertical rod 6, and the two ends of the spring 4 at the upper end are respectively connected to the top plate 3 and the upper slider 5, and the two ends of the spring 4 at the lower end are respectively connected to the bottom plate 8 and the lower slider 5, and the outer surface of the slider 5 is fixedly connected with a clamping plate 7, and the inner end surface of the clamping plate 7 is provided with an anti-slip groove.

[0023] It should be noted that the processing and fixing mechanism can be flexibly adjusted according to the different models and sizes of the workpiece, and has strong adaptability. The slider 5 is slidably connected to the vertical rod 6, and the clamping plate 7 provides clamping force through the spring 4 to ensure that the workpiece will not loosen or displace during the fixing process, thereby improving the stability and uniformity of the processing process. The anti-slip groove design increases the friction force to ensure the stability and safety of the workpiece during the processing and prevent the workpiece from sliding.

[0024] When in use, place the workpiece between the top plate 3 and the bottom plate 8 of the processing fixing mechanism, ensuring that the workpiece is located in the middle of the clamping plate 7. After the workpiece is placed, the spring 4 on the vertical rod 6 will automatically apply force to move the clamping plate 7 to achieve the effect of clamping the workpiece.

[0025] Please refer to Figure 1 As shown, the chain conveyor 1 is provided with a preheating powder spraying mechanism, which includes a preheating box 9 and a heating pipe 10. Transparent movable grooves 11 are opened on both sides of the preheating box 9, and the chain conveyor 1 is arranged through the movable groove 11. A plurality of evenly distributed heating pipes 10 are fixedly installed on the inner walls of both sides of the preheating box 9. A powder spraying chamber 18 is provided at the rear end of the preheating box 9. In the powder spraying chamber 18, the workpiece can be sprayed manually or automatically. This processing method has been widely used in the existing technology and will not be described in detail here.

[0026] It should be noted that the multiple heating tubes 10 evenly distributed on the inner wall of the preheating box 9 can ensure that the workpiece is fully and evenly preheated before entering the powder spraying process, effectively improving the adhesion of the powder and the uniformity of the coating, and avoiding coating quality problems caused by local overheating or insufficient heating.

[0027] Please refer to Figure 1 and Figure 2 As shown, the front and rear end faces of the preheating box 9 are both provided with an airflow surrounding mechanism, and the airflow circulation mechanism includes a slide rail 15 and a fan 14. The front and rear end faces of the preheating box 9 are fixedly connected to two upper and lower distributed slide rails 15, and the outer surface of the slide rail 15 is fixedly connected to the fan 14. The front and rear end faces of the preheating box 9 are both provided with a plurality of evenly distributed circulation grooves 17, and a matching dustproof net 16 is fixedly installed in the circulation groove 17. A baffle 13 is slidably connected between the upper and lower slide rails 15 on the same side, and the outer end surface of the baffle 13 is fixedly connected to the handle 12.

[0028] It should be noted that: the airflow surrounding mechanism uses the combination of the fan 14 and the slide rail 15 to enable the hot air to evenly surround the workpiece, achieve all-round preheating, and avoid local overheating or cold spots. After the fan 14 blows the external air into the preheating box 9, the airflow is fully mixed with the hot air in the preheating box 9 through the filtration and diversion design of the circulation groove 17 and the dustproof net 16, ensuring that the airflow temperature entering the preheating box is more uniform. The dustproof net 16 not only filters dust, but also plays a role in diversion and airflow homogenization to ensure that the airflow temperature is uniform.

[0029] The baffle 13 between the slide rails 15 can be flexibly adjusted according to the preheating requirements of different workpieces. By pushing and pulling the handle 12 to change the position of the baffle 13, part of the flow slot 17 can be selectively blocked to control the flow and direction of the airflow, improve the controllability of the preheating effect, and avoid uneven heating and cooling. Through uniform preheating, the workpiece surface reaches the ideal powder spraying temperature, and the powder coating can melt and adhere better during powder spraying to form a uniform coating, thereby improving the powder spraying quality and the durability of the coating.

[0030] The working principle of the powder spraying device for processing the charging pile shell provided by the utility model is as follows:

[0031] 1. Workpiece fixing and transportation:

[0032] The workpiece is fixed by a processing fixing mechanism, and the spring 4 provides an automatic adjustment force to ensure that workpieces of different sizes can be firmly clamped and moved along with the chain conveyor 1;

[0033] 2. Preheat treatment:

[0034] After the workpiece is fixed, it enters the preheating box 9. A plurality of heating tubes 10 are evenly distributed on the inner wall of the preheating box. The air in the preheating box is heated by the heating tubes 10 to ensure that a uniform high temperature environment is maintained in the box.

[0035] 3. Airflow adjustment:

[0036] The front and rear ends of the preheating box are equipped with airflow surround mechanisms. The slide rails 15 and the shielding plate 13 can flexibly adjust the flow rate and direction of the airflow according to specific needs. By adjusting the position of the shielding plate, the airflow distribution is controlled to ensure the uniformity and stability of the airflow in the preheating box.

[0037] 4. Powder spraying:

[0038] The evenly preheated workpiece enters the powder spraying area under the drive of the chain conveyor 1. The even preheating enables the powder coating to melt and adhere quickly when it contacts the workpiece surface, forming a uniform coating, thereby improving the powder spraying effect and the durability of the coating.

[0039] In summary, the utility model realizes continuous transportation and stable fixation of the workpiece through the chain conveyor 1 and the processing fixing mechanism, realizes uniform preheating of the workpiece through the powder spraying preheating mechanism and the air flow surrounding mechanism, and ensures high quality and high efficiency of the powder spraying process.
