Description

Technical Field

[0001] The invention belongs to the technical field of insulation treatment in metal wire processing, and in particular relates to a continuous production line for enameled wires. Background Art

[0002] At present, in the process of processing metal wires, some fields need to use metal wires with external insulation for conductive connection, and then need to apply paint on the outer surface of the metal wire, and then dry the paint so that it is firmly attached to the metal wire to improve the insulation performance of the outer surface of the metal wire. During the processing, the paint is generally applied to the surface of the metal wire by a coating roller or a nozzle, so that the entire processing process is continuous. However, due to the use of a coating roller or a nozzle to apply the paint, it is impossible to ensure that the paint can fully cover the surface of the metal wire, and it is very easy to leak locally, thereby reducing the insulation and quality of the metal wire. Moreover, after the paint is applied, when a drying device is used to dry the paint, in order to ensure the drying effect, it is necessary to increase the drying time and / or the effective drying length of the drying device, thereby making the space occupied by the entire drying device larger, the energy consumption of the drying device higher, and the drying efficiency lower.

DETAILED DESCRIPTION

[0036] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] The present invention discloses a continuous production line for enameled wires, such as Figure 1-17As shown, it includes a V-shaped enameling machine, a vertical cyclone drying device 200 and a reciprocating sliding winding device 300. One or more metal wires unwound by the wire unwinding machine pass through the V-shaped enameling machine and the vertical cyclone drying device 200 in sequence, and are wound in the reciprocating sliding winding device 300. The V-shaped enameling machine of the present invention includes a V-shaped paint coating mechanism 100, an inclination adjustment mechanism, i.e., two wire guide mechanisms, wherein the V-shaped paint coating mechanism 100 is connected to the frame through the inclination adjustment mechanism, and the two wire guide mechanisms are respectively connected to the inlet and outlet ends of the V-shaped paint coating mechanism 100. The present invention can determine whether cooling is required based on the temperature of the metal wire after it is led out of the vertical cyclone drying device 200. Generally, air cooling is used for cooling to avoid drastic temperature changes of the metal wire and the occurrence of cracking of the paint that has not yet stabilized under thermal stress. The working principle and advantages of the present invention are as follows: the present invention continuously coats one or multiple metal wires in parallel with paint through a V-shaped enameling machine, and then the metal wires are dried by a vertical cyclone drying device 200 and then rolled up on one or more winding drums on a reciprocating sliding winding device 300. The V-shaped paint coating mechanism 100 of the V-shaped enameling machine of the present invention adopts a V-shaped design, and the inclination angle of the V-shaped paint coating mechanism 100 is adjusted by an inclination adjustment mechanism to ensure that the paint can be fully attached to the surface of the metal wire during the metal wire passes through the V-shaped paint coating mechanism 100, and the uniformity and expected thickness of the paint layer are ensured, so as to avoid uneven thickness of the paint layer, or the paint layer is too thin or too thick, that is, if the paint layer is too thin, the insulation performance of the metal wire is low, and if the paint layer is too thick, the weight of the metal wire is large, and the consumption of the paint increases sharply, which increases the processing cost. Moreover, after adjusting the inclination angle of the V-shaped paint coating mechanism 100, the two wire guiding mechanisms of the present invention can smoothly and smoothly guide the metal wire into and out of the V-shaped paint coating mechanism 100, playing the role of guiding and transitioning the metal wire. The present invention adopts a vertical swirl drying device 200, and the metal wire passes through the vertical swirl drying device 200 in the vertical direction, and the drying gas swirls through the vertical swirl drying device 200 in the vertical direction, which increases the contact time and comprehensiveness of the drying gas and the metal wire, thereby allowing the outer surface of the metal wire to be fully dried. One or more winding drums are installed in the reciprocating sliding winding device 300, and one or more metal wires are wound on the corresponding winding drums after drying, and during the reciprocating motion of the reciprocating sliding winding device 300, the metal wire is evenly wound. In summary, the present invention can effectively improve the comprehensiveness of paint coating on the surface of the metal wire, ensure that the outer surface of the metal wire has excellent insulation properties, and enable the paint to be quickly dried and solidified on the metal wire, thereby improving the drying efficiency, reducing the energy consumption of the equipment, and reducing the space occupied by the equipment.

[0038] As a preferred embodiment of the present invention, Figure 2-5 As shown, the V-shaped paint coating mechanism 100 includes a V-shaped base 101 and a V-shaped opening and closing seat 103, both of which are V-shaped, and the angle of the V-shaped is a, and the range of a is 53°-70°. The V-shaped opening and closing seat 103 is arranged at the upper end of the V-shaped base 101, and pivoting ears 104 are respectively constructed on both sides of one end of the V-shaped opening and closing seat 103, and pivoting ears 104 are also respectively constructed on both sides of the same end of the V-shaped base 101.

A fixing ear 105 is respectively constructed on both sides of the other end of the V-shaped opening and closing seat 103, and a fixing ear 105 is also respectively constructed on both sides of the same end of the V-shaped base 101. The V-shaped opening and closing seat 103 and the corresponding fixing ears 105 in the V-shaped base 101 are connected together by a fastening bolt 138, and a fastening nut 139 is threadedly connected to the fastening bolt 138. In this embodiment, a V-shaped coating cavity is formed between the V-shaped base 101 and the V-shaped opening and closing seat 103, and the paint is injected into the V-shaped coating cavity. The V-shaped angle of the V-shaped coating cavity is also a. In this embodiment, the fastening bolt 138 can be removed, and then the V-shaped opening and closing seat 103 can be opened along the axis of the pivot shaft 137 to open the V-shaped coating cavity, clean the V-shaped coating cavity, or replace a metal wire of a different type, and guide the metal wire through the two wire guide mechanisms and the V-shaped coating cavity. After completion, the V-shaped opening and closing seat 103 is buckled on the V-shaped base 101, and the two are connected by the fastening bolt 138 and the fastening nut 139. In this embodiment, the angle of the V-shaped coating cavity is adjusted by the inclination adjustment mechanism, so that the paint in the V-shaped coating cavity is tilted toward the inlet end or the outlet end face, thereby adjusting the time for the metal wire to interact with the paint during the wire entry and wire arrangement process, while ensuring that the paint is fully attached to the surface of the metal wire, avoiding the situation where too little or too much paint is attached.

In this embodiment, paint overflow parts 102 are symmetrically formed on both sides of the V-shaped base 101, each paint overflow part 102 has an overflow cavity 111, and an overflow notch 112 is formed at the upper part of the overflow cavity 111, one overflow notch 112 is connected to the junction of the inlet channel 106 and the inlet immersion channel 107, and the other overflow notch 112 is connected to the junction of the outlet channel 110 and the outlet immersion channel 109.

The paint inlet pipe 113 and the paint outlet pipe 116 are respectively installed with a feed control valve 114 and a discharge control valve 117. The working principle and advantages of this embodiment are as follows: this embodiment limits the limit value of the paint injected into the V-shaped coating cavity through two overflow cavities 111, adjusts the inclination angle of the V-shaped coating cavity through the inclination adjustment mechanism, and then adjusts the amount of paint in the inlet immersion channel 107 and the outlet immersion channel 109, so that the paint is fully attached to the outer surface of the metal wire, and the outlet immersion channel 109 is adjusted with the adjustment of the inclination adjustment mechanism, and cooperates with the wire guide mechanism at the outlet end, so that when the metal wire leaves the outlet immersion channel 109, the paint attached to the surface of the metal wire is in a uniform state. This embodiment replenishes the V-shaped coating cavity with paint through the paint inlet pipe 113, discharges the excess paint out of the overflow cavity 111 through the paint overflow pipe 115, and then discharges it through the paint outlet pipe 116.

The first adapter ring 131 is rotatably connected to the transition roller 129. The lower end of the vertical rod 130 movably passes through the V-shaped base 101. A first connecting spring 133 is sleeved outside the vertical rod 130. The two ends of the first connecting spring 133 are respectively connected to the V-shaped base 101 and the first fixed edge 132. The structure of the wire guide mechanism of this embodiment is that the wire guide mechanism includes a wire roller 119, two first adapter shafts 121, two second adapter shafts 123 and two adapter rods 125. Among them, the wire roller 119 extends along the side-by-side arrangement direction of multiple metal wires, and two first adapter shafts 121 are coaxially constructed at the two ends of the wire roller 119. A first connecting flange 122 is constructed at the end of each first adapter shaft 121 away from the wire roller 119, and a second connecting flange 124 is constructed at the axial end of each second adapter shaft 123.

When the tension of the metal wire changes, the force of the metal wire on the transition roller 129 and the two wire rollers 119 changes, so that each first connecting spring 133 and each second connecting spring 128 undergoes corresponding elastic deformation to absorb most of the external force, thereby preventing the metal wire from being deformed or broken due to excessive tension.

The plurality of vertical tube drying mechanisms are arranged side by side, and the lower parts of the vertical tube drying mechanisms are connected one by one with the plurality of air intake branches 222 on the air intake main pipe 221, and the upper parts of the vertical tube drying mechanisms are connected one by one with the plurality of air outlet branches 225 on the air outlet main pipe 224. The specific structure of the vertical tube drying mechanism of this embodiment is that the vertical tube drying mechanism includes a vertical cyclone tube 201, a lower air inlet hood 206, an upper exhaust hood 215, an inlet guide nozzle 220 and an outlet guide nozzle 211, and an upper internal threaded joint 205 and a lower internal threaded joint 204 are respectively constructed at the upper and lower ends of the vertical cyclone tube 201, a lower external threaded joint 207 is constructed at the upper end of the lower air inlet hood 206, and an upper external threaded joint 216 is constructed at the lower end of the upper exhaust hood 215, the lower external threaded joint 207 of the lower air inlet hood 206 is threadedly connected to the lower internal threaded joint 204 of the vertical cyclone tube 201, and the upper external threaded joint 216 of the upper exhaust hood 215 is threadedly connected to the upper internal threaded joint 205 of the vertical cyclone tube 201. In this embodiment, a slow flow chamber 209 and a first transition chamber 210 are formed vertically upward in the lower air intake hood 206, and a second transition chamber 218 and a converging chamber 219 are formed vertically upward in the upper exhaust hood 215. The first transition chamber 210 and the second transition chamber 218 are respectively connected to the lower end and the upper end of the drying chamber 202 of the vertical cyclone 201. A cyclone groove 203 extending spirally along its axis is constructed on the inner wall of the vertical cyclone 201. An air intake joint 208 and an exhaust joint 217 are respectively constructed on the lower air intake hood 206 and the upper exhaust hood 215. The air intake joint 208 is connected to the slow flow chamber 209, and the exhaust joint 217 is connected to the converging chamber 219. The inlet guide nozzle 220 and the outlet guide nozzle 211 are respectively threadedly connected at the center of the upper exhaust hood 215 and the center of the lower air intake hood 206. The structures of the inlet guide nozzle 220 and the outlet guide nozzle 211 of this embodiment are completely the same. Taking the outlet guide nozzle 211 as an example, it is divided into multiple types according to the number and type of metal wires. This embodiment takes three representative outlet guide nozzles 211 as an example. Figure 13-15As shown, a first wire circular hole 212 is provided at the center of the first wire outlet guide nozzle 211, which is adapted to allow a metal wire to pass through, and the radial length of the first wire circular hole 212 is adapted to the radial length of the metal wire. A plurality of second wire circular holes 213 are evenly provided along the circumference of the second wire outlet guide nozzle 211, so as to facilitate the passage of a plurality of metal wires, or these second wire circular holes 213 are arranged at intervals along a straight line, so that a plurality of metal wires pass through the second wire circular holes 213 in a side-by-side direction. A wire rectangular hole 214 is provided on the third wire outlet guide nozzle 211, which is adapted to allow a metal wire with a rectangular radial cross section to pass through. The working principle and advantages of this embodiment are as follows: the drying gas enters each of the plurality of inlet branches 222 through the inlet main pipe 221, and then enters the slow flow chamber 209 through the inlet joint 208, reducing the flow rate of the drying gas, and making the drying gas enter the drying chamber 202 uniformly through the first transition chamber 210; in the process of the drying gas moving upward, under the action of the swirl groove 203, the drying gas generates a swirl, thereby making the paint on the surface of the metal wire fully dried, and the drying time of the drying gas in the drying chamber 202 is longer, thereby ensuring that the paint is completely dried after the metal wire leaves. The dried gas continues to swirl upward, and then enters the confluence chamber 219 through the second transition chamber 218, and finally enters the outlet main pipe 224 through the exhaust joint 217 and the outlet branch pipe 225 and is discharged.

The output shaft of the forward and reverse motor 311 is coaxially connected to one axial end of the transmission screw 312. In this embodiment, the driving motor 306 is controlled to rotate, so that it drives the assembly rod 309 to rotate through the transmission of the active bevel gear 305 and the passive bevel gear 308. During the rotation, the assembly rod 309 drives the winding drum to wind the metal wire onto the winding drum. At the same time, the forward and reverse motor 311 is controlled to rotate alternately east and west, so that the transmission screw 312 drives the mounting seat 301 to reciprocate along the axial direction of the assembly rod 309, thereby making the metal wire evenly wound on the winding drum.
