Description
Technical Field
[0001] This utility model relates to the field of rubber polymer coating technology, specifically to a rubber polymer coating equipment with anti-electro-erosion function. Background Technology
[0002] As is well known, traditional spraying equipment and technologies face a series of challenges in the surface treatment of rubber polymer workpieces, especially when it comes to coatings that provide anti-electrochemical corrosion protection. During spraying, the high-speed flow of liquid or powder particles between the spray gun and the workpiece generates static charge. This static charge accumulates continuously without an effective release pathway, leading to a potential difference between the workpiece and the spraying equipment. Once this potential difference exceeds a certain threshold, electrochemical corrosion occurs, which not only affects the coating quality but can also damage the workpiece. To prevent this, existing spraying equipment typically adds insulating materials to critical areas such as the spray gun to reduce charge accumulation. However, this method provides only limited protection because it cannot completely eliminate the potential difference. Furthermore, relying solely on physical isolation cannot dynamically adjust potential changes, so electrochemical corrosion often affects the spraying effect in complex working environments. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1-4 This utility model is a rubber polymer coating equipment with anti-electro-erosion function, including a spray box 1. The front of the spray box 1 has an opening 2 and an adjustment groove. An insulating coating is provided around the opening 2, and an insulating sealing mechanism is provided on the opening 2. The spray box 1 is equipped with a ventilation mechanism and a spray gun 3. The spray gun 3 is equipped with an insulating sleeve. A bearing seat 4 is located at the bottom of the spray box 1, and an insulating disc 5 is located on the bearing seat 4. A rotating mechanism is provided between the bottom of the spray box 1 and the insulating disc 5. An equipotential bonding line 6 is located at the top of the insulating disc 5. A potential monitoring sensor 7, an equipotential adjustment module 8, and a line interface 9 are provided between the equipotential bonding line 6 and the adjustment groove. A controller 10 is provided on the spray box 1, and a line connector 11 is provided between the controller 10 and the line interface 9. In this embodiment, the controller 10 is inserted into the adjustment groove, thereby allowing the line connector 11 to be inserted into the line interface 9. The workpiece is placed on the insulating disk 5, and the workpiece contacts and rests against the top of the equipotential bonding line 6. The potential difference is detected by using a point monitoring sensor, which triggers the equipotential adjustment module 8, such as a thyristor or relay, to dynamically adjust the conduction state and balance the potential between the spray box 1 and the substrate in real time. The spray gun 3 is connected to the pipeline of the spraying supply equipment, so that the spray gun 3 can spray the workpiece on the insulating disk 5. Through the above-mentioned potential balancing, the insulating coating around the opening 2, and the insulating sleeve on the spray gun 3, the occurrence of electro-erosion is suppressed from the root, forming a dual protection system of physical isolation and potential balance, which ensures the surface coating effect of the rubber polymer workpiece. During the spraying process, the insulating disk 5 is rotated back and forth by a rotating mechanism, which can improve the spraying efficiency and uniformity of the rubber polymer workpiece. The bearing seat 4 can improve the rotational stability of the insulating disk 5, and the reciprocating rotation can effectively prevent the equipotential bonding line 6 from getting tangled in the bearing seat 4.
[0016] To facilitate the rotation of the insulating disk 5, in this design, the rotation mechanism includes a rotating motor 12, which is installed at the bottom of the spray box 1. The output end of the rotating motor 12 extends to the center of the bearing seat 4 and is connected to the bottom of the insulating disk 5. By controlling the output end of the rotating motor 12 to rotate the bottom of the insulating disk 5, the rotational stability of the insulating disk 5 can be ensured, and the rotating motor 12 located at the bottom of the spray box 1 can be maintained linearly.
[0017] To ensure the insulation and sealing of opening 2, in this solution, the insulation sealing mechanism includes a lifting hole and an insulating cover 13. The lifting hole is located at the top of opening 2, and the insulating cover 13 is located on the lifting hole. By moving the insulating cover 13 downward in the lifting hole to block opening 2, the spraying operation can be facilitated, and it can be free from external interference, further ensuring the anti-electrolytic corrosion effect.
[0018] To improve spraying efficiency, in this solution, two spray guns 3 are provided and symmetrically arranged. The two symmetrically arranged spray guns 3 can further improve the efficiency of spraying and coating rubber polymer material workpieces.
[0019] In order to improve the fastening of the controller 10 in the adjustment groove, in this solution, damping pads 14 are provided at the top and bottom of the adjustment groove. The damping pads 14 at the top and bottom are in tight contact with the controller 10, which can improve the stability of the controller 10 in the fastening box.
[0020] To ensure both ventilation and insulation, the ventilation mechanism in this design includes a ventilation pipe 15, which is installed on the rear side of the spray box 1. An insulating filter 16 is provided on the ventilation pipe 15. By using an insulating filter 16 made of insulating material, the ventilation pipe 15 can prevent dust from entering the opening 2, ensuring the quality of the spray coating while providing insulation, and further ensuring the anti-electrolytic corrosion effect.
[0021] To facilitate viewing equipotential information via a network terminal, the controller 10 in this solution is equipped with a wireless transmission module, which enables the control information of the controller 10 to be easily transmitted to the network terminal.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
