Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire production, in particular to a magnetic suspension painting die device for a vertical enameling machine. Background Art

[0002] Varnishing is the process of applying wire paint to a conductor, creating a uniform layer of a certain thickness. Currently, two main varnishing methods are used: die-coating and felt-coating. Die-coating is suitable for high-viscosity paints and high-speed production. Its main advantages are easy control of film thickness, solvent savings, cost reduction, and reduced pollution. Therefore, die-coating is the most common varnishing method.

[0003] Die coating involves passing a painted conductor through a die with a specific hole shape and size. The gap between the conductor and the die core maintains the paint liquid at a certain thickness, which is then baked to form a film. As the conductor passes through the die, which gradually increases in size, the desired film thickness is achieved.

[0004] At present, the enameling machines on the market mainly adopt the design of fixed molds. The wires pass through the fixed molds, and the mold is partially suspended by the buoyancy of the paint. This method is greatly affected by factors such as paint viscosity, temperature, and flow rate, which will lead to poor suspension stability of the mold, and then lead to uneven painting, resulting in a high rate of small paint film, affecting the quality and performance of the wires. Utility Model Content

[0005] The purpose of the utility model is to provide a magnetic suspension painting die device for a vertical enameling machine, which uses magnetic suspension technology to enable the painting die to remain stably suspended during the wire painting process, thereby improving the quality of painting.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a magnetic levitation painting mold device for a vertical enameling machine, comprising a support assembly, a painting mold, an annular magnet and an electromagnetic coil, the painting mold is arranged in the support assembly, the annular magnet is coaxially sleeved on the painting mold, the electromagnetic coil is fixedly mounted on the support assembly, and the electromagnetic coil and the annular magnet are coaxially arranged.

[0007] The technical principle of the utility model is as follows: when the wire passes through the painting mold, the buoyancy of the paint will suspend the painting mold. The device generates magnetic levitation force through the electromagnetic coil and the annular magnet. When the painting mold is affected by factors such as paint viscosity, temperature, flow rate, etc., the magnetic levitation force will offset this part of the force.

[0008] Furthermore, the support assembly includes a back plate, a first limit plate and a second limit plate. The back plate is arranged on the painting machine. The first limit plate and the second limit plate are both horizontally fixedly installed on the back plate, and a space is left between the first limit plate and the second limit plate. The painting mold is arranged between the first limit plate and the second limit plate. The first limit plate is provided with a first through hole, and the second limit plate is provided with a second through hole coaxially arranged with the first through hole. The electromagnetic coil is fixedly installed on the side of the second limit plate away from the first limit plate.

[0009] Furthermore, a first opening is formed on the first limiting plate, and the first opening is communicated with the first through hole. A second opening is formed on the second limiting plate, and the second opening is communicated with the second through hole.

[0010] Furthermore, the support assembly also includes a shielding plate, which is vertically fixedly mounted on the back plate, and the shielding plate is arranged on both sides of the first limiting plate and the second limiting plate.

[0011] Furthermore, a protective shell is provided outside the electromagnetic coil, and the protective shell is fixedly mounted on a side of the second limiting plate away from the first limiting plate.

[0012] Furthermore, it also includes a Hall sensor and a controller. The Hall sensor is fixedly installed on the electromagnetic coil. The Hall sensor is electrically connected to the controller, and the controller is electrically connected to the electromagnetic coil.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through magnetic levitation technology, the painting mold can maintain stable suspension during the wire painting process, thereby improving the quality of painting.

[0015] 2. By setting the shielding plate, the interference of environmental factors on the electromagnetic coil can be reduced, making the device more stable, thereby further improving the quality of painting.

[0016] 3. Through the Hall sensor and controller, the current of the electromagnetic coil can be adjusted in real time, so that the magnetic field strength can be dynamically adjusted, which can keep the painting mold stably suspended in the air and improve the quality of painting.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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, rather than all the embodiments; the structures described in various embodiments can be freely combined without any conflict in structure or principle.

[0024] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., etc., are used solely for distinction and description, and should not be construed as indicating or implying relative importance.

[0026] Below with reference to accompanying drawing some embodiment of the present utility model is described:

[0027] like Figure 1-Figure 3 As shown, the utility model proposes a magnetic levitation painting mold device for a vertical enameling machine, including a support assembly 1, a painting mold 2, an annular magnet 3 and an electromagnetic coil 4. The painting mold 2 is arranged in the support assembly 1, the annular magnet 3 is coaxially sleeved on the painting mold 2, and the electromagnetic coil 4 is fixedly installed on the support assembly 1, and the electromagnetic coil 4 is coaxially arranged with the annular magnet 3.

[0028] As the wire 5 passes through the painting mold 2, the buoyancy of the paint causes the painting mold 2 to levitate. This device energizes the electromagnetic coil 4, generating a magnetic field opposite to that of the annular magnet 3, creating a magnetic levitation force. This magnetic levitation force offsets the vibrations of the painting mold 2 due to factors such as paint viscosity, temperature, and flow rate, ensuring that the painting mold 2 remains stably suspended during the painting process, thereby improving the quality of the painting. The annular magnet 3 can utilize a high-performance rare earth magnet, such as a neodymium iron boron magnet, to ensure sufficient magnetic force.

[0029] Furthermore, if Figure 1 and Figure 2 As shown, the support assembly 1 includes a back plate 101, a first limit plate 102 and a second limit plate 103. The back plate 101 is arranged on the painting machine. The first limit plate 102 and the second limit plate 103 are both horizontally fixedly installed on the back plate 101, and a space is left between the first limit plate 102 and the second limit plate 103. The painting mold 2 is arranged between the first limit plate 102 and the second limit plate 103. A first through hole 1021 is opened on the first limit plate 102, and a second through hole 1031 is opened on the second limit plate 103 which is coaxial with the first through hole 1021. The electromagnetic coil 4 is fixedly installed on the upper side of the second limit plate 103.

[0030] The painting mold 2 has a certain weight. When the present device is not in use, the first limit plate 102 can support the painting mold 2; when the present device is in use, the second limit plate 103 can prevent the painting mold 2 from being lifted too high by the buoyancy of the paint. The first limit plate 102 and the second limit plate 103 can make the painting mold 2 always move in the space between the first limit plate 102 and the second limit plate 103. The first through hole 1021 and the second through hole 1031 are used to pass the wire 5.

[0031] Furthermore, if Figure 1 and Figure 2 As shown, the first limiting plate 102 has a first opening 1022 , which is communicated with the first through hole 1021 . The second limiting plate 103 has a second opening 1032 , which is communicated with the second through hole 1031 .

[0032] The lead 5 can be easily removed from the device through the first opening 1022 and the second opening 1032 .

[0033] Furthermore, if Figure 1 and Figure 3 As shown, the support assembly 1 further includes a shielding plate 104 , which is vertically fixedly mounted on the back plate 101 , and is disposed on both sides of the first limiting plate 102 and the second limiting plate 103 .

[0034] Shielding plate 104 is made of a magnetically isolating material, such as copper, aluminum, or silver-plated metal. Here, shielding plate 104 is preferably made of aluminum. In actual production, several of these devices can be arranged side by side to simultaneously produce several conductors 5, or they can be arranged in two rows and arranged in a cross-wise manner. Shielding plate 104 not only reduces environmental interference with electromagnetic coil 4 but also prevents mutual interference between multiple devices, making the device more stable and thus further improving the quality of the paint finish.

[0035] Furthermore, if Figure 1 and Figure 2 As shown, a protective shell 6 is provided outside the electromagnetic coil 4 , and the protective shell 6 is fixedly mounted on the upper side of the second limiting plate 103 .

[0036] By providing the protective shell 6 , the electromagnetic coil 4 can be protected, thereby reducing the possibility of damage to the electromagnetic coil 4 .

[0037] Furthermore, if Figure 1 As shown, it also includes a Hall sensor (not shown in the figure) and a controller (not shown in the figure). The Hall sensor is fixedly mounted on the electromagnetic coil 4 , the Hall sensor is electrically connected to the controller, and the controller is electrically connected to the electromagnetic coil 4 .

[0038] Hall sensors measure the magnetic field strength of electromagnetic coil 4 in real time. The location and number of Hall sensors are optimized based on specific design requirements to ensure accurate and timely measurements. The controller receives signals from the Hall sensors and adjusts the current in electromagnetic coil 4 in real time, dynamically adjusting the magnetic field strength to maintain stable suspension of the mold. The control system utilizes a high-precision PID control algorithm to ensure the mold remains in a stable suspension state despite external interference. This allows the mold to maintain optimal position and posture during the painting process, ensuring uniform paint film distribution, reducing film undershoot, and improving paint quality.

[0039] In addition, to ensure the normal operation of the electromagnetic coil 4 and the control system, a power supply module is also provided. It provides a stable power supply. This module has good voltage and current regulation capabilities to meet the power requirements under different working conditions.
