DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0035] As described in the background art, it is difficult to uniformly coat the inside and outside of a power pipe, resulting in poor coating efficiency.

[0036] In order to solve this technical problem, the present invention provides a coating device for processing electric power pipes, which is used for internal and external coating.

[0037] Specifically, please refer to Figure 1-Figure 5The coating equipment for processing electric pipes comprises a base 1 and a processing seat 2 symmetrically movable on the base 1, a coating assembly 3 located on one side of the processing seat 2 is arranged on the base 1, the coating assembly 3 comprises a coating mechanism 30 and a return air mechanism 31, the coating mechanism 30 comprises a vertical plate 301, a liquid storage tank 302 and a driving motor 303, the vertical plate 301 is mounted on the base 1, the liquid storage tank 302 is connected to the vertical plate 301, the driving motor 303 is mounted on the vertical plate 301, the output end is connected to a connecting rod 304, the free end of the connecting rod 304 is mounted with a coating water pump 305, the free end of the coating water pump 305 is connected with a coating pipe 306, and the coating pipe 306 is connected with a plurality of coating nozzles 307;

[0038] The return air mechanism 31 includes return air fan blades 310, return air baffles 311 and one-way valves 312. Multiple return air fan blades 310 are connected to the coating pipe 306. The return air baffles 311 and the one-way valve 312 are respectively installed on the return air fan blades 310 and relatively distributed. Guide tubes 313 are installed on the multiple return air fan blades 310. A rotating guide plate 314 is installed on the liquid storage tank 302. A power supply battery 315 connected to the guide tube 313 is slidably fitted on the rotating guide plate 314.

[0039] The driving motor 303 is started, driving the connecting rod 304 to rotate. At this time, the coating water pump 305 is working. The coating water pump 305 draws paint from the liquid storage tank 302 and transports it to multiple coating nozzles 307 through the coating pipe 306. The coating nozzle 307 sprays the paint evenly on the power pipe to achieve coating of the power pipe. When the paint is sprayed from the coating nozzle 307, a certain airflow is generated. This airflow drives the return air fan blades 310 connected to the coating pipe 306 to rotate. The return air baffle 311 and the one-way valve 312 have the effect of control and opening and closing, so as to prevent the coating material from dripping directly when the coating pipe 306 rotates. The air with paint particles eventually returns to the coating pipe 306 through the power supply battery 315 and the rotating guide plate 314, so as to achieve paint recovery and reuse.

[0040] The present invention provides a coating device for processing electric power pipes, which can evenly spray paint on the electric power pipes through the coating nozzle 307, thereby improving the efficiency and quality of coating. The cooperation between the driving motor 303 and the coating water pump 305 can adjust the flow rate and pressure of the paint as needed to meet the coating requirements of electric power pipes of different specifications. The return air mechanism 31 can effectively recover the paint particles that are not attached to the electric power pipes, thereby reducing the waste of paint and lowering the production cost.

[0041] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0043] It should be noted that similar reference numerals and letters indicate similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0044] Please refer to Figure 7-Figure 8 A coating device for processing electric pipes, wherein a pretreatment mechanism 32 is arranged on a base 1, and the pretreatment mechanism 32 comprises a pretreatment collection base 320, an electric telescopic rod 321 and a double-headed cylinder 322. The pretreatment collection base 320 is installed on the base 1 and connected to the two electric telescopic rods 321, and the output end of the electric telescopic rod 321 is connected to the double-headed cylinder 322, and the two output ends of the double-headed cylinder 322 are connected to a coating plate 323, and the four coating plates 323 are connected to two guide rods 324, and the guide rods 324 are equipped with two force springs, and the end surface of the force spring of the guide rod 324 is connected to a positioning mounting plate installed with a mounting plate 325, and the four coating plates 323 are connected to the mounting plate 325, and one side of the mounting plate 325 is provided with a coating cloth strip rubber outer cleaning strip connected to the coating plate 323 326; by controlling the extension and retraction of the two electric telescopic rods 321, the height position of the double-headed cylinder 322 and the coating plate 323 connected thereto can be adjusted so that it can adapt to power pipes of different sizes so as to better fit the outer surface of the power pipe. When the coating plate 323 is adjusted to a suitable position, the coating cloth strip and the rubber outer cleaning strip 326 connected to the coating plate 323 will contact the outer surface of the power pipe. During the movement or rotation of the power pipe, the coating cloth strip and the rubber outer cleaning strip 326 clean the surface of the power pipe to remove dust, impurities, etc. on the surface. The force spring on the guide rod 324 can make the coating cloth strip and the rubber outer cleaning strip 326 always maintain a certain pressure to fit the surface of the power pipe to ensure the cleaning effect. At the same time, the positioning mounting plate can guide and position the movement of the guide rod 324.

[0045] By pre-treating the surface of the power pipe to remove dust, impurities, etc., a clean surface can be provided for subsequent coating work, which greatly improves the quality and adhesion of the coating. The arrangement of the electric telescopic rod 321 and the double-headed cylinder 322 enables the pre-treatment mechanism 32 to adapt to power pipes of different sizes, thereby improving the versatility and flexibility of the equipment.

[0046] Please refer to Figure 7-Figure 8A coating device for processing electric power pipes, wherein a cleaning mechanism 33 is arranged on a coating plate 323, and the cleaning mechanism 33 comprises a magnetic plate 330, a rubber inner cleaning strip 331 and a guide roller 332. The magnetic plates 330 are symmetrically arranged in the electric power pipe and are magnetically connected to the coating plate 323, the rubber inner cleaning strip 331 is symmetrically connected to the magnetic plates 330, and the guide roller 332 is installed at the outer center of the four magnetic plates 330; the magnetic plates 330 are symmetrically arranged in the electric power pipe and are magnetically connected to the coating plate 323 by magnetic force. This connection method is convenient for installation and disassembly, and can It can be flexibly adjusted according to the size and shape of the power pipe. The rubber inner cleaning strip 331 contacts the inner surface of the power pipe. When the power pipe moves or is coated, the magnetic plate 330 remains connected to the coating plate 323 under the action of magnetic force and moves with the movement of the power pipe. The rubber inner cleaning strip 331 slides on the inner surface of the power pipe to clean the inner surface of the power pipe and remove internal dust, impurities, etc. The guide roller 332 is installed at the outer center of the four magnetic plates 330 to guide and reduce friction, so that the magnetic plate 330 can move more smoothly in the power pipe.

[0047] The rubber inner cleaning strip 331 can effectively clean the inner surface of the power pipe to ensure that the interior is clean and tidy, providing a good foundation for subsequent coating work. The symmetrically arranged rubber inner cleaning strip 331 can fully cover the inner surface of the power pipe to improve the uniformity and thoroughness of cleaning. The magnetic connection method makes the installation and disassembly of the cleaning mechanism 33 very convenient without the use of complex fixing devices.

[0048] A coating device for power pipe processing is further optimized, specifically, as Figure 2-Figure 11 As shown, a recovery mechanism 34 is provided on the pretreatment collection base 320, and the pretreatment collection base 320 cooperates with the recovery mechanism 34 to achieve the effect of recycling the coating material. The recovery mechanism 34 includes a recovery water pump 340, a recovery pipe 341 and a guide plate 342. The recovery water pump 340 is installed on the base 1. The input end is connected to the pretreatment collection base 320 through a connecting pipe. The recovery pipe 341 is connected to the output end of the recovery water pump 340. The guide rod 324 is symmetrically connected to the pretreatment collection base 320. The two guide plates 342 are installed between them. There is a filter plate 343; the pretreatment collection base 320 will collect the coating materials and impurities cleaned from the surface of the power pipe during the pretreatment of the power pipe. The recovery water pump 340 generates suction to suck the coating materials in the pretreatment collection base 320 through the connecting pipe, and then the coating materials are discharged through the recovery pipe 341 by the recovery water pump 340 for secondary utilization. When the mixed liquid is sucked out from the pretreatment collection base 320, it will first be filtered by the filter plate 343. The filter plate 343 blocks larger particles of impurities to achieve preliminary filtration and separation.

[0049] The coating material recovered by the pretreatment collection base 320 can be used again in the coating operation after processing, thereby improving material utilization, keeping the working environment clean, and timely recovering excess materials and impurities, preventing the pretreatment collection base 320 from accumulating too much liquid and impurities, avoiding affecting the normal operation of the pretreatment mechanism 32, and improving the reliability and stability of the entire coating equipment.

[0050] Further, such as Fig.10 , Fig.11 As shown, an enlarged vibration groove is provided on the pretreatment collection base 320, and a support plate 344 in the enlarged vibration groove is installed on the guide plate 342, and a positioning rod 345 is connected to the support plate 344, and vibration springs respectively connected to the positioning rod 345 and the enlarged vibration groove are symmetrically installed on the positioning rod 345; when the support plate 344 is pushed by the guide rod 324 to generate displacement, the vibration spring will be compressed or stretched, thereby generating an elastic restoring force, and this elastic restoring force will make the support plate 344 vibrate back and forth within a certain range, thereby affecting the filter plate 343 installed between the two guide plates 342, and the filter plate 343 can prevent the coating material and impurities from accumulating and clogging on the surface of the filter plate 343 under the action of vibration.

[0051] Vibration prevents the coating material and impurities on the surface of the filter plate 343 from accumulating, thereby keeping the filter plate 343 unobstructed, extending the service life of the filter plate 343, and reducing the need for frequent cleaning or replacement of the filter plate 343 due to blockage of the filter plate 343.

[0052] A coating device for power pipe processing is further optimized, specifically, as Figure 3-Figure 6 As shown, a power cord connected to the driving device of the return fan blade 310 is connected inside the guide tube 313, and one end of the guide tube 313 passes through the surface of the coating pipe 306; the return fan blade 310 requires electric drive to rotate, and the power cord is connected to the driving device of the return fan blade 310 and is wired through the guide tube 313. One end of the guide tube 313 passes through the surface of the coating pipe 306, so that the power cord can be connected from the outside of the coating pipe 306 to the driving device of the return fan blade 310 located on the coating pipe 306.

[0053] By using the guide tube 313 to arrange the power cord, the wiring is made more neat and standardized, avoiding the power cord being distributed in a disorderly manner around the device. The guide tube 313 can protect the power cord and prevent the power cord from being damaged by the external environment, such as wear, extrusion, corrosion, etc. At the same time, it also reduces the situation where the power cord is accidentally pulled or cut.

[0054] Further, such as Figure 2As shown, a recovery pipe 341 is installed on the pretreatment collection base 320, and a nozzle corresponding to the mounting plate 325 is connected to the recovery pipe 341; one end of the recovery pipe 341 is connected to the output end of the recovery water pump 340, and the liquid containing the coating material recovered from the pretreatment collection base 320 is transported out, and the liquid can be redirected back to the coating cloth in the coating process through the recovery pipe 341, and the recovery pipe 341 is connected to the nozzle corresponding to the mounting plate 325, and these nozzles can deliver the recovered liquid to the coating cloth.

[0055] Through the cooperation of the recovery pipe 341 and the nozzle, the recovered coating material liquid is reused, thereby reducing material waste and lowering production costs.

[0056] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
