Description

Technical Field

[0001] This utility model belongs to the field of technical technology, specifically, it relates to an insulating varnish coating device for enameled wire. Background Technology

[0002] Enameled wire is a type of electromagnetic wire made by coating a metal conductor with an insulating varnish layer. It is widely used in electrical equipment such as motors, transformers, and inductors. The uniformity and curing quality of the insulating varnish layer directly affect the electrical properties, mechanical strength, and heat resistance of the enameled wire. Traditional enameled wire coating processes typically include steps such as coating, leveling, and drying. However, the following problems still exist in actual production:

[0003] Existing drying methods mostly use fixed hot air nozzles or electric heating tubes. The uneven distribution of hot air may lead to incomplete curing or over-baking of the paint film in some areas, affecting the adhesion of the paint layer. During the feeding process, the insulating paint is prone to sticking to the inner wall of the material box due to insufficient fluidity or temperature changes, resulting in poor material supply and requiring manual intervention to clean it, which affects production efficiency.

[0004] To address the aforementioned problems, this application proposes an insulating varnish coating device for enameled wires. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an insulating varnish coating device for enameled wires to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An insulating varnish coating device for enameled wire includes a coating cylinder with guide holes at both ends, a material box fixedly installed on the top of the coating cylinder, the material box being connected to the coating cylinder, and a drying cylinder installed at one end of the coating cylinder, with an opening at one end of each drying cylinder.

[0008] The drying mechanism includes an annular positioning box, which is fixedly installed on the outside of the paint coating cylinder. An air injection pipe is connected to one side of the annular positioning box, and an annular exhaust box is rotatably connected to one side of the annular positioning box. The annular exhaust box is rotatably connected to one end of the drying cylinder, and multiple nozzles are connected to one side of the annular exhaust box.

[0009] The vibration mechanism includes a positioning seat, which is fixedly installed on one side of the material box, and a sliding rod is slidably connected to the positioning seat. A striking hammer is fixedly installed at the top of the sliding rod, and the striking hammer cooperates with the positioning seat.

[0010] Preferably, the drying mechanism further includes an annular connecting hole, which is opened on one side of the annular positioning box, and multiple through holes are opened on one side of the annular exhaust box, which are interconnected with the annular connecting hole.

[0011] The gas inside the annular positioning box is introduced into the annular exhaust box through the annular connecting hole and through hole, and finally sprayed out through the nozzle.

[0012] Preferably, the air outlet of the nozzle is offset by 30 degrees along the center direction of the annular exhaust box, and the air outlet of the nozzle is offset by 15 degrees along the tangent direction of the annular exhaust box.

[0013] The nozzle's air outlet is offset by 30 degrees along the center of the annular exhaust box, so that the nozzle's air outlet acts on the coated wire, thereby quickly drying the outer coating. The nozzle's air outlet is also offset by 15 degrees along the tangent of the annular exhaust box, so that the nozzle's air outlet pushes the annular exhaust box to rotate in the opposite direction, thereby ensuring that the sprayed gas can act evenly on the enameled wire.

[0014] Preferably, the vibration mechanism further includes a protrusion, which is fixedly installed on the outside of the annular exhaust box, and a stop is fixedly installed at the bottom end of the slide rod, with the stop engaging with the protrusion in a pushing-pushing manner.

[0015] The rotating annular exhaust box drives the protrusion to rotate, and the protrusion, in cooperation with the stop block, pushes the slide rod upward.

[0016] Preferably, a top spring is fixedly installed on the top of the stop block, and the top end of the top spring is fixedly connected to the bottom of the positioning seat.

[0017] The top spring allows the push block to move downwards, which in turn moves the slide rod downwards, causing the hammer to strike the positioning seat and act on the material box. This vibration of the material box facilitates its rapid downward sliding and prevents sticking.

[0018] In summary, the technical effects and advantages of this utility model are as follows:

[0019] The nozzle employs a dual-angle offset design (30° in the center direction + 15° in the tangential direction), which allows hot air to directly act on the enameled wire to accelerate drying. At the same time, the reaction force drives the annular exhaust box to rotate, so that the sprayed hot air can evenly cover the circumference of the wire, avoiding local overheating or uneven drying. The rotating connection structure (through hole + annular connection hole) between the annular exhaust box and the positioning box allows for continuous hot air delivery while allowing rotation. The structure is compact and efficient.

[0020] The kinetic energy of the rotating annular exhaust box is used to trigger the slide bar to move up and down through the mechanical linkage of the protrusion and the stop, converting the rotational energy into impact vibration. No additional power source is required, making it energy-saving and highly reliable. The top spring reset design ensures that the hammer periodically strikes the material box, preventing the insulating varnish from adhering or clogging and improving the fluidity of the coating.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-5 An insulating varnish coating device for enameled wire includes a coating cylinder 1 with guide holes at both ends, a material box 2 fixedly installed on the top of the coating cylinder 1, the material box 2 and the coating cylinder 1 being interconnected, and a drying cylinder 3 installed at one end of the coating cylinder 1, with an opening 6 at one end of each drying cylinder 3.

[0030] The drying mechanism 4 includes an annular positioning box 41, which is fixedly installed on the outside of the paint coating cylinder 1. An air injection pipe 42 is connected to one side of the annular positioning box 41, and an annular exhaust box 43 is rotatably connected to one side of the annular positioning box 41. The annular exhaust box 43 is rotatably connected to one end of the drying cylinder 3, and multiple nozzles 44 are connected to one side of the annular exhaust box 43.

[0031] The vibration mechanism 5 includes a positioning seat 51, which is fixedly installed on one side of the material box 2. A slide rod 52 is slidably connected to the positioning seat 51, and a hammer 53 is fixedly installed at the top of the slide rod 52. The hammer 53 and the positioning seat 51 cooperate with each other.

[0032] Reference Figure 1 andFigure 4 The drying mechanism 4 also includes an annular connecting hole 46, which is located on one side of the annular positioning box 41. Multiple through holes 45 are provided on one side of the annular exhaust box 43, and these through holes 45 communicate with the annular connecting hole 46. The outlet of the nozzle 44 is offset by 30 degrees along the center direction of the annular exhaust box 43, and by 15 degrees along the tangent direction of the annular exhaust box 43. Gas from the annular positioning box 41 is introduced into the annular exhaust box 43 through the annular connecting hole 46 and the through holes 45, and finally sprayed out through the nozzle 44. The outlet of the nozzle 44 is offset by 30 degrees along the center direction of the annular exhaust box 43, allowing the outlet of the nozzle 44 to act on the coated wire, thereby rapidly drying the outer coating. Furthermore, the outlet of the nozzle 44 is offset by 15 degrees along the tangent direction of the annular exhaust box 43, causing the outlet of the nozzle 44 to push the annular exhaust box 43 to rotate in the opposite direction, thus ensuring that the sprayed gas acts evenly on the enameled wire.

[0033] Reference Figure 1 The vibration mechanism 5 also includes a protrusion 56, which is fixedly installed on the outside of the annular exhaust box 43. A stop block 54 is fixedly installed at the bottom of the slide rod 52. The stop block 54 and the protrusion 56 push against each other. A top spring 55 is fixedly installed on the top of the stop block 54. The top of the top spring 55 is fixedly connected to the bottom of the positioning seat 51. The rotating annular exhaust box 43 drives the protrusion 56 to rotate. The protrusion 56, through its cooperation with the stop block 54, can push the slide rod 52 to move upward. Through the setting of the top spring 55, the stop block 54 can be pushed downward. Then, through the downward movement of the slide rod 52, the hammer 53 is driven to strike the positioning seat 51 and act on the material box 2, so that the material box 2 vibrates and the material box 2 slides down quickly to prevent sticking.

[0034] Working principle: During operation, the drying cylinder 3 and the coating cylinder 1 are simultaneously fixed on the wire feeding device. When the wire is fed, it passes through the guide holes at both ends of the coating cylinder 1 and the opening 6 of the drying cylinder 3. The heated insulating varnish is placed in the material box 2. Under the action of gravity, the insulating varnish is introduced into the coating cylinder 1 and fills the entire area of ​​the wire. When the wire is wound up, the insulating varnish adheres to the wire for coating. At the same time, hot air is injected into the annular positioning box 41 through the air injection pipe 42. The gas in the annular positioning box 41 is introduced into the annular exhaust box 43 through the annular connecting hole 46 and the through hole 45, and finally sprayed out through the nozzle 44. The air outlet of the nozzle 44 is offset by 30 degrees along the center direction of the annular exhaust box 43, so that the air outlet of the nozzle 44 acts... On the coated wire, the outer coating is dried quickly. The air outlet of the nozzle 44 is offset by 15 degrees along the tangent of the annular exhaust box 43, so that the air outlet of the nozzle 44 pushes the annular exhaust box 43 to rotate in the opposite direction, so that the sprayed gas can be evenly applied to the enameled wire. At the same time, the rotating annular exhaust box 43 drives the protrusion 56 to rotate. The protrusion 56, through its cooperation with the stop block 54, can push the slide rod 52 to move upward. Through the setting of the top spring 55, it can push the stop block 54 to move downward, and then the slide rod 52 moves downward, thereby driving the hammer 53 to hammer the positioning seat 51 and act on the material box 2, so that the material box 2 vibrates and makes it easy for the material box 2 to slide down quickly, preventing sticking.
