Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire drying, in particular to an automatic drying device for enameled wire production. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of two parts: conductor and insulation layer. The bare wire is annealed and softened, then painted and baked several times. It is affected by factors such as raw material quality, process parameters, production equipment, and environment, so the quality characteristics of various enameled wires are different.

[0003] When drying enameled wire, the evaporated water will be distributed in the drying box, increasing the humidity inside the box and affecting the drying effect. At present, water vapor is generally extracted by an air pump, but when the air pump is running, the gas in the box will flow rapidly, and the flow of gas will affect the heat distribution inside the box, thereby affecting the drying and shaping effect of the paint layer on the surface of the wire. In addition, when the air pump extracts water vapor, it will bring the heat out of the box, causing the heat inside the box to be lost quickly, affecting the drying efficiency. In view of this, we propose an automatic drying device for enameled wire production. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 6 , a technical solution provided by the utility model:

[0028] An automatic drying device for enameled wire production includes a drying box 1, one end of which is provided with a box door 4, the drying box 1 is provided with a first through hole 11, the door 4 is provided with a second through hole 41, the first through hole 11 and the second through hole 41 are coaxially arranged for the enameled wire to pass through.

[0029] In this embodiment, a heating mechanism 2 is provided inside the drying box 1 for providing heat required for drying.

[0030] Specifically, the heating mechanism 2 in this embodiment includes a heating module 21, which is fixedly mounted on the inner wall of the drying box 1. A support rod 22 is fixedly connected to the heating module 21. One end of the support rod 22 extends from the opening into the drum 32 and is fixedly connected to a spiral resistance wire 23. The spiral resistance wire 23 is spirally arranged at the center of the drum 32. When in use, the spiral resistance wire 23 can be wrapped around the outside of the enameled wire to heat the enameled wire circumferentially so that the outer periphery of the enameled wire is heated evenly. The heating module 21 is electrically connected to the spiral resistance wire 23.

[0031] When the enameled wire is dried by the traditional drying method, the evaporated water will be distributed in the drying box 1, increasing the humidity inside the box and affecting the drying effect. The water vapor needs to be pumped out by an air pump, but the flow of gas will affect the heat distribution inside the box and bring the heat out of the box, affecting the drying and shaping quality of the paint layer on the surface of the wire. For this reason, a dehumidification and heat collection mechanism 3 is provided in the drying box 1 in this embodiment.

[0032] Specifically, the dehumidification and heat collection mechanism 3 includes a support frame 31, which is fixedly installed in the drying box 1. A rotating drum 32 is rotatably installed on the inner wall of the support frame 31, and the rotating drum 32 is coaxially arranged with the first through hole 11 and the second through hole 41. The rotating drum 32 is sleeved on the outside of the spiral resistance wire 23 to collect the heat of the spiral resistance wire 23.

[0033] Furthermore, a plurality of folding plates 34 are fixedly connected to the inner wall of the rotating drum 32, and the folding plates 34 are distributed in a circular array with the axis of the rotating drum 32 as the center. There is a gap between the folding plates 34 and the inner wall of the rotating drum 32, and the dehumidification cylinder 33 is inserted into the gap. The outer wall of the dehumidification cylinder 33 contacts the rotating drum 32, and the inner wall contacts the folding plates 34, which is clamped between the rotating drum 32 and the folding plates 34, so that the dehumidification cylinder 33 can be easily disassembled and replaced. The dehumidification cylinder 33 is made of a porous structure such as activated carbon, which can effectively absorb water vapor.

[0034] Furthermore, the interior of the rotating drum 32 is a hollow structure, and one end thereof is gathered toward the middle to form a cone shape to reduce the diffusion of heat. The other end of the rotating drum 32 is provided with an opening, and a conical cover 35 is threadedly connected to one end of the opening. A through hole is provided at one end of the conical cover 35 for the enameled wire to pass through. By providing the conical cover 35, the dehumidification drum 33 can be easily replaced.

[0035] In addition, the dehumidification heat collection mechanism 3 also includes a support plate 39, which is fixedly installed in the drying box 1, and a driving motor 38 is fixedly installed on the support plate 39. A driving gear 37 is fixedly installed at the output end of the driving motor 38. A gear ring 36 is meshed on the surface of the driving gear 37, and the gear ring 36 is fixedly installed on the rotating drum 32. Through the meshing of the driving gear 37 and the gear ring 36, the rotating drum 32 can be driven to rotate, thereby rotating the dehumidification drum 33, so that the dehumidification drum 33 can be fully in contact with water vapor, thereby improving the dehumidification effect.

[0036] When the automatic drying device for enameled wire production of the utility model is used, the enameled wire is sequentially passed through the first through hole 11, the rotating drum 32, the conical cover 35 and the second through hole 41, and the heating module 21 and the driving motor 38 are started. The heating module 21 provides power to make the spiral resistance wire 23 generate heat, so that the water on the surface of the enameled wire evaporates, and the enameled wire is dried. The water vapor diffuses around the enameled wire and is absorbed by the dehumidification cylinder 33 inside the rotating drum 32, so that the surrounding area of ​​the enameled wire remains dry.

[0037] The output end of the driving motor 38 drives the driving gear 37 to rotate, and the driving gear 37 drives the gear ring 36 to rotate through meshing. The gear ring 36 synchronously drives the rotating drum 32 to rotate, and then drives the dehumidification drum 33 to rotate, so that the dehumidification drum 33 is in uniform contact with the water vapor, so as to better absorb the water vapor around the enameled wire.

[0038] After a period of time, the cabinet door 4 can be opened, and the conical cover 35 can be rotated so that the conical cover 35 is threadably separated from the rotating drum 32, so that the dehumidification drum 33 can be replaced.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
