Description

Technical Field

[0001] This utility model relates to the field of cable coating spraying technology, and in particular to a low-smoke coating spraying device for fireproof cable surfaces. Background Technology

[0002] A low-smoke coating spraying device for fire-resistant cables is used in the production process of fire-resistant cables to spray coatings onto the surface of the cables to achieve functions such as insulation, corrosion prevention, and wear resistance, thereby improving the performance and quality of the fire-resistant cables. It eliminates the need for manual spraying, reducing direct contact between workers and the coating during manual spraying, reducing the harm to workers' health caused by harmful gases and dust, and improving the working environment in the production workshop.

[0003] During the production of cables, multiple processes are required to obtain the finished cable. Among these processes, the application of insulating varnish is a crucial indicator to ensure the safe use of the cable. Existing technology provides a spraying device for wire and cable manufacturing (publication number CN218982067U). This utility model includes a base, on the top of which a conductor block is fixedly installed. The surface of the conductor block has wire holes, and one end of the conductor block is equipped with a guide component. The varnish is sprayed onto the surface of the cable through a nozzle. During the spraying process, a signal is transmitted to a stepper motor to control its forward and reverse rotation, thereby further deflecting the nozzle at a certain angle to ensure uniform application of the insulating varnish.

[0004] Existing patent (publication number: CN222490685U) discloses a spraying device for manufacturing wires and cables, including a base plate, a second annular tube with multiple sets of inclined second nozzles arranged in a circular array, and a heating box with multiple sets of electric heating wires for air heating. Through the design of the structure of the blower, electric heating wires, conveying pipe, second annular tube and second nozzles, the blower can supply air to the heating box, the electric heating wires can heat the air delivered to the heating box, the conveying pipe can deliver hot air to the second annular tube, and the second nozzles on the second annular tube can spray the hot air onto the cable, thereby drying the insulating varnish on the cable. When the cable is conveyed in the second connecting pipe, the heated air can further dry the insulating varnish on the cable as it exits the conveying pipe, thereby accelerating the drying efficiency of the insulating varnish on the cable and improving the spraying production efficiency of the cable.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, current spraying devices used in the production of fire-resistant cables simply move the fire-resistant cable directly into the spray booth and then spray it directly. While this method allows for direct spraying of the fire-resistant cable, it fails to guide and clean the cable before spraying. Without guidance and cleaning, not only will the adhesion of the insulating varnish on the surface of the fire-resistant cable be affected, but the quality of the finished fire-resistant cable will also be compromised, resulting in insufficient practicality.

[0006] To address this, a low-smoke coating spraying device for fire-resistant cable surfaces is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a low-smoke coating spraying device for fire-resistant cables. This device solves the problem that existing fire-resistant cable manufacturing spraying devices directly move the fire-resistant cable into the spray booth and then spray it directly. Although this method can directly spray the fire-resistant cable, it cannot guide and clean the fire-resistant cable before spraying. Without guidance and cleaning, it will not only affect the adhesion of the insulating paint on the surface of the fire-resistant cable, but also affect the quality of the finished fire-resistant cable, resulting in insufficient practicality.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a low-smoke coating spraying device for fireproof cables, comprising a processing table, a cleaning mechanism fixedly connected to the top of the processing table, a guiding mechanism fixedly connected to the top of the processing table, and a limiting mechanism fixedly connected to the top of the processing table;
