Description

Technical Field

[0001] This utility model relates to the field of coating spraying technology, and in particular to a high-temperature resistant coating spraying machine for cables. Background Technology

[0002] As an essential component of power transmission and communication infrastructure, cables require excellent corrosion resistance, mechanical strength, electrical performance, and safety. Applying a high-temperature resistant coating to the cable surface significantly improves its high-temperature resistance, enabling it to operate stably in harsher environments, extending its service life, and meeting the high-performance requirements of modern industry.

[0003] Existing high-temperature resistant coating spraying machines for cables consist of a transport mechanism, a spraying mechanism, and a drying mechanism. The transport mechanism holds the cable and moves it forward at a constant speed via a conveyor belt. The spraying mechanism uses a high-pressure spray gun to atomize the high-temperature resistant coating and spray it onto the cable surface. The coating is applied by adjusting the angle of the spray gun. The drying mechanism uses infrared heating to heat and cure the freshly sprayed coating as the cable moves. However, the following problems still exist: 1. High-temperature resistant coatings need to maintain stability in high-temperature environments. Since the spraying mechanism only operates by adjusting the angle of the spray gun, it is difficult to fully cover the cable surface, which can easily lead to spraying dead spots and local coatings that are too thin. Under high-temperature conditions, the insulation layer is prone to carbonization. Uneven coating affects the high-temperature resistance of the cable. At the same time, the amount of spraying cannot be controlled. Insufficient spraying will not only reduce the coating quality, but excessive spraying will also waste paint and increase production costs.

[0004] 2. Because the conveyor belt clamping size of the transport mechanism is fixed, it is difficult to quickly adjust to meet the requirements of stable transport when handling cables with different specifications such as diameter and length. During the cable transport process, the cable is prone to deviation and shaking due to improper clamping force of the conveyor belt and inaccurate positioning. This will not only lead to uneven coating coverage and the risk of missed spraying in the subsequent spraying process, but also make the heating and curing effect of the coating by the drying mechanism unstable. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a high-temperature resistant coating spraying machine for cables, which aims to improve the problems of dead corners, uneven coating, inaccurate control of spraying amount, and paint waste in the existing spraying mechanism for cable surfaces. At the same time, it solves the problems of insufficient adaptability of equipment to cables of different specifications in the background technology, as well as the problems of reduced efficiency of subsequent processing steps and affected product quality due to cable transportation problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-temperature resistant coating spraying machine for cables includes an equipment frame, a spraying mechanism is provided inside the equipment frame, and a limiting mechanism is provided at both ends of the equipment frame; The spraying mechanism includes multiple semi-circular frames, the exterior of which is fixedly connected to the left side of the inner side of the equipment frame. Multiple flow tubes are fixedly connected inside each semi-circular frame, and multiple concentrators are fixedly connected inside each flow tube. Flat nozzles are fixedly connected to the exterior of each concentrator. Multiple guide tubes are fixedly connected to the exterior of each semi-circular frame, and a flow divider valve is fixedly connected to the other end of each guide tube. An adjustment knob is fixedly connected to the exterior of each flow divider valve, and a storage component is installed at the other end of each adjustment knob. A drive component is installed at the top of the equipment frame, a collection component is installed at the bottom left side of the equipment frame, and a drying component is installed at the right side of the inner side of the equipment frame.

[0007] As a further description of the above technical solution: the limiting mechanism includes a connection port, the outside of which is fixedly connected to one end of the equipment frame, and the other end of which is fixedly connected to a transport pipe. Multiple support frames are fixedly connected inside the transport pipe, and a bracket is slidably connected inside the support frame. Two return springs are sleeved on one end of the bracket that is close to the support frame. Grooved wheels are rotatably connected to the adjacent side of the bracket, and the outer end of the return spring is supported inside the support frame.

[0008] As a further description of the above technical solution: the storage component includes an infusion tube, one end of which is fixedly connected to the other end of the diversion valve, and the other end of which is fixedly connected to a sealed container, with a fixing frame fixedly connected to the bottom outer side of the sealed container; the drive component includes a booster pump, the bottom of which is fixedly connected to the top of the equipment frame, the output end of which is fixedly connected to a gas delivery pipe, and the other end of which is fixedly connected to the top of the sealed container.

[0009] As a further description of the above technical solution: the collection component includes a leak, the top of which is fixedly connected to the top left side of the equipment frame, and a collection box is fixedly connected to the bottom of the leak; the drying component includes a temperature controller, the outside of which is fixedly connected to the outside of the equipment frame, and a wrapping frame is fixedly connected to the output end of the temperature controller. Multiple heating tubes are fixedly connected inside the wrapping frame, and the heating tubes are electrically connected to the temperature controller; the outside of the drainage tube is fixedly connected to the outside of the equipment frame, and the outside of the diversion valve is fixedly connected to the top of the equipment frame; one end of a single drainage tube is connected to a single flow tube, and the central tube connects multiple flow tubes in series.

[0010] This utility model has the following beneficial effects: 1. In this invention, four semi-circular frames distributed vertically and horizontally drive the internal flow tubes, concentrators, and flat nozzles to form a surrounding layout, providing all-around coating coverage of the cable surface. This avoids dead zones and ensures the integrity of the coating. Multiple flow tubes are connected in series via the concentrator, allowing the coatings from different flow tubes to mix within the concentrator. A diversion valve and its connected adjustment knob control the coating flow rate in the guide tube, achieving a comprehensive, uniform, and controllable coating effect on the cable surface. This ensures coating quality and improves coating utilization efficiency. The surrounding spraying ensures no dead zones for high-viscosity coatings, preventing insulation failure due to partial coating gaps at high temperatures. Precise flow control matches the rheological properties of different high-temperature resistant coatings, reducing the risk of coating cracking caused by over-coating. 2. In this utility model, the cooperation between the connection port and the transport pipe enables the cable to stably enter and exit the equipment frame. The cooperation between the support frame, bracket, and return spring allows the grooved wheel to flexibly adjust its position according to the cable diameter and tightly fit the cable. Furthermore, the grooved wheel rotates with the cable during transport, thus solving the problems of cable deviation during transport, difficulty in stably limiting cables of different diameters, and damage caused by excessive friction between the cable surface and the limiting components. The adaptive limiting mechanism is compatible with cable thermal expansion deformation, preventing scratches caused by mechanical extrusion before the coating is cured; the low-friction grooved wheel reduces damage to the pre-treatment layer on the cable surface, ensuring coating adhesion.

[0011] 3. The drying component precisely controls the temperature of the heating tube through a temperature controller to achieve gradient heating, matching the curing curves of different high-temperature resistant coatings, and avoiding blistering or peeling of the coating due to sudden temperature changes; the uniform thermal field distribution of the wrapping frame can improve the cross-linking density of the coating, enabling it to maintain stable dielectric strength and mechanical properties in high-temperature environments.

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] Reference Figure 1 , Figure 3 and Figure 4 One embodiment of this utility model is a cable high-temperature resistant coating spraying machine, which includes a device frame 1, which can provide a stable installation foundation and protective shell for the entire device. The device frame 1 is provided with a spraying mechanism 2, which can uniformly spray a high-temperature resistant coating on the surface of the cable.

[0016] The spraying mechanism 2 includes multiple semi-circular frames 21, which can conform to the curved surface of the cable for easy all-around spraying. The external parts of the multiple semi-circular frames 21 are fixedly connected to the inside left side of the equipment frame 1 to ensure stable installation of the semi-circular frames 21. Four semi-circular frames 21 are installed, with their installation directions being up, down, left, and right, to achieve full coverage.

Three concentrators 23 are installed outside the three flow pipes 22, and flat nozzles 24 are fixedly connected to the outside of each concentrator 23, which allows the coating to be sprayed out in a flat shape, increasing the spraying area. Multiple drainage pipes 25 are fixedly connected to the outside of the semi-circular frame 21, which can guide the paint to the flow pipe 22. The number of drainage pipes 25 and flow pipes 22 is the same. The other end of each drainage pipe 25 is fixedly connected to a diversion valve 26, which can control the diversion direction and flow rate of the paint. Each diversion valve 26 is fixedly connected to an adjusting knob 27, which can be rotated to adjust the opening degree of the diversion valve 26.

One end of a single drain pipe 25 is connected to a single flow pipe 22 to achieve precise delivery of paint. The central pipe 23 connects multiple flow pipes 22 in series to mix the paint.

[0017] The storage component 28 includes a delivery tube 281 for conveying the paint in the sealed container 282 to the diversion valve 26. One end of the delivery tube 281 is fixedly connected to the other end of the diversion valve 26 to ensure unobstructed paint delivery. The other end of the delivery tube 281 is fixedly connected to the sealed container 282 to seal and store the paint, preventing it from deteriorating or leaking. A mounting bracket 283 is fixedly connected to the bottom outer side of the sealed container 282 to stably support it. The drive component 29 includes a booster pump 291 that generates high-pressure gas to propel the paint flow. The bottom of the booster pump 291 is fixedly connected to the top of the equipment frame 1 to ensure stable installation. The output end of the booster pump 291 is fixedly connected to a gas delivery tube 292 for delivering high-pressure gas to the sealed container 282. The other end of the gas delivery tube 292 is fixedly connected to the top of the sealed container 282 to ensure that the high-pressure gas can smoothly enter the sealed container 282.

[0018] Reference Figure 2 , Figure 3 and Figure 5 The collection component 4 includes a drain 41, which guides excess paint into a collection box 42. The top of the drain 41 is fixedly connected to the top left side of the equipment frame 1 to catch dripping paint. The bottom of the drain 41 is fixedly connected to the collection box 42 for storing the collected excess paint. The drying component 5 includes a temperature controller 51, which controls the temperature of the heating tube 53.

Multiple heating tubes 53 are fixedly connected inside the wrapping frame 52 to generate heat to dry the coating. The heating tubes 53 are electrically connected to the temperature controller 51 to achieve precise temperature control.

[0019] Reference Figure 1 , Figure 2 and Figure 6 The limiting mechanism 3 includes a connection port 31 for connecting the equipment frame 1 and the transport pipe 32. The connection port 31 is fixedly connected to one end of the equipment frame 1 to ensure the stability of the connection. The other end of the connection port 31 is fixedly connected to the transport pipe 32 to provide a channel for the cable to enter and exit. Multiple support frames 33 are fixedly connected inside the transport pipe 32 to support the bracket 35 and the return spring 34. The bracket 35 is slidably connected inside the support frame 33, which can drive the grooved wheel 36 to move to accommodate cables of different diameters. Two return springs 34 are sleeved on the end of the bracket 35 that is close to the support frame 33. The elastic force can make the grooved wheel 36 fit tightly against the cable. The grooved wheel 36 is rotatably connected to the adjacent side of the bracket 35. It can rotate with the cable and reduce the friction on the cable surface. The outer end of the return spring 34 is supported inside the support frame 33 to provide a force point for the return spring 34 to generate elastic force.

[0020] Working principle: During operation, the cable enters the equipment through the transport pipe 32 of the limiting mechanism 3. The return spring 34 in the support frame 33 pushes the bracket 35 through elastic force, so that the groove wheel 36 is in close contact with the cable surface, limiting its movement trajectory while rotating with the cable to reduce friction. The booster air pump 291 of the drive component 29 generates high-pressure gas, which enters the sealed tank 282 of the storage component 28 through the gas delivery pipe 292. It pushes the coating through the liquid delivery pipe 281 into the diversion valve 26. After the flow rate is controlled by adjusting the knob 27, the coating enters the flow pipe 22 of the spraying mechanism 2 through the guide pipe 25, and is then collected by the concentrator pipe 23 and sprayed out from the flat nozzle 24. The four semi-circular frames 21 distributed up, down, left and right achieve all-round uniform spraying of the cable surface. During the spraying process, excess paint flows into the collection box 42 through the drain 41 of the collection component 4 for recycling. The coated cable enters the drying component 5 on the right side of the equipment frame 1. The temperature controller 51 controls the heating tube 53 in the wrapping frame 52 to generate appropriate heat to quickly dry the coating on the surface of the cable. Finally, the processed cable is sent out of the equipment through the limiting mechanism 3 at the other end.
