Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of the insulation treatment of the outer surface of metal wires, and particularly relates to a varnishing machine and a varnishing method thereof. BACKGROUND

[0002] At present, in the deep processing of metal wires, the surface of the metal wires needs to be insulated so as to facilitate the subsequent use of electricity. In the insulation treatment of the metal wires, the paint is uniformly covered on the outer surface of the metal wires. Specifically, the liquid low-viscosity paint or the paint with high viscosity is coated on the metal wires. That is, when the liquid low-viscosity paint is used, the paint is sprayed on the metal wires in the atomized manner. In this manner, due to the limitations of the spraying angle and range, it is impossible to ensure that the surface of one or more metal wires is fully sprayed, and the dead angle or uneven spraying is prone to occur. When the paint with high viscosity is used, the paint is filled into a paint tank, and one or more metal wires continuously pass through the paint tank so as to be immersed in and pass through the paint. However, in this manner, the contact time of the metal wires with the paint is relatively long, and in general, the metal wires pass through the paint tank in the horizontal direction. On the one hand, the paint attached to the surface of the metal wires is inevitably too thick, and on the other hand, the attached paint gradually moves downward under the action of gravity, so that the thickness of the paint on the surface of the metal wires is uneven, thereby affecting the insulation performance of the outer surface of the metal wires.

DETAILED DESCRIPTION

[0044] The preferred embodiments of the present application will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to explain and illustrate the present application, and are not used to limit the present application.

[0045] The present application discloses a paint wrapping machine, such as Figures 1-14As shown, it comprises a paint spraying box 100, a fixed base 200, an adjustable guiding unit, a driving mechanism 400 and a plurality of angle-adjustable rotary paint spraying mechanisms 300. The plurality of angle-adjustable rotary paint spraying mechanisms 300 are arranged side by side and are in transmission connection with the driving mechanism 400. The upper part of each angle-adjustable rotary paint spraying mechanism 300 extends into the paint spraying box 100 from the lower end of the paint spraying box 100 and is in rotary connection with the paint spraying box 100. The lower end of the angle-adjustable rotary paint spraying mechanism 300 is detachably connected to the fixed base 200 which is fixedly connected to the paint spraying box 100 through a plurality of adapter plates 600. The fixed base 200 of the present application comprises a base body 201 on which a plurality of through openings 203 are arranged side by side. Each through opening 203 is in communication with the lower end of the corresponding angle-adjustable rotary paint spraying mechanism 300 to facilitate the passage of metal wires. Fixed plates 202 are arranged on both sides of the base body 201 and are detachably connected to the frame. The adjustable guiding unit is connected above the paint spraying box 100 and comprises a plurality of multi-wire angle adjusting mechanisms 500, each of which is arranged in one-to-one correspondence with the angle-adjustable rotary paint spraying mechanism 300. The working principle and advantages of the present application are as follows: the driving mechanism 400 drives each angle-adjustable rotary paint spraying mechanism 300 so that the low-viscosity paint sprayed by the angle-adjustable rotary paint spraying mechanism 300 assumes a spiral flow shape. In this way, the spiral flow atomized paint can spray the metal wires without dead angles, ensuring that the paint uniformly covers the outer surface of the metal wires. By adjusting the multi-wire angle adjusting mechanism 500, the angle of the metal wires entering the angle-adjustable rotary paint spraying mechanism 300 is adjusted, and the paint spraying angle of the angle-adjustable rotary paint spraying mechanism 300 is adjusted according to the specific situation. After adjustment, the atomized taper and range are changed during the rotation of the driven angle-adjustable rotary paint spraying mechanism 300. The change in the delivery angle of the metal wires cooperates to uniformly spray the outer periphery of the metal wires, avoiding the occurrence of dead angles and paint thickness deviations. The present application can also pass high-viscosity paint into the angle-adjustable rotary paint spraying mechanism 300. The high-viscosity paint fills the channel of the angle-adjustable rotary paint spraying mechanism 300. During the rotation of the angle-adjustable rotary paint spraying mechanism 300, the viscous paint in the channel is driven upward by the rotation of the angle-adjustable rotary paint spraying mechanism 300. On the one hand, this avoids the flow of such paint from the lower end of the channel under the action of gravity, and on the other hand, it ensures that the metal wires pass through the paint vertically, ensuring that the outer surface of the metal wires is uniformly coated, avoiding the occurrence of dead angles and paint thickness deviations. In summary, the present application can adapt to the coating of low-viscosity paint and high-viscosity paint on metal wires, ensuring that the paint uniformly covers the outer surface of the metal wires and avoiding the occurrence of dead angles and uneven paint thickness, thereby improving the insulation performance of the outer surface of the metal wires.

The driving sprocket 402 and the driven sprocket 403 are in transmission connection through a transmission chain 404, or the driving synchronous pulley and the driven synchronous pulley are in transmission connection through a synchronous belt. In the embodiment, a plurality of paint spraying assemblies are hinged on the upper end surface of the rotating distribution member. The paint spraying assemblies are uniformly arranged along the circumference of the rotating distribution member, and the paint spraying assemblies are respectively hinged with the inclination angle adjusting assemblies, which are installed on the upper end of the rotating distribution member. A wire passage 302 is formed at the center of the wire vertical cylinder 301, and a metal wire passes through the angle-adjustable rotary paint spraying mechanism 300 through the wire passage 302. The working principle and advantages of the embodiment are as follows: the driving motor 401 drives the rotation of each driven sprocket 403 or driven synchronous pulley, and then the rotating distribution member drives the rotation of the paint spraying assemblies and the inclination angle adjusting assemblies. In this way, before the metal wire enters the wire passage 302, the atomized paint is uniformly attached to the surface of the metal wire. The inclination angle of each paint spraying assembly is adjusted by adjusting the posture of the inclination angle adjusting assembly, so that the spraying cone and range of the atomized paint are adjusted when the paint spraying assembly is driven to rotate along the axis of the wire passage 302. Or the paint with high viscosity enters the wire passage 302, and the paint is attached to the surface of the metal wire during the process of the metal wire passing through the wire passage 302.

In this embodiment, the ring-shaped adjusting seats 507 of the two adjacent multi-wire angle adjusting mechanisms 500 are fixedly connected, and the ring-shaped adjusting seats 507 at the two ends of the paint spraying box 100 are respectively connected with an adapter lug 509. Fixed lugs 106 are arranged at the upper ends of the paint spraying box 100 at the two ends, respectively. A vertical screw rod 510 is threadedly connected to each adapter lug 509, and the lower end of the vertical screw rod 510 is rotatably connected to the corresponding fixed lug 106. An operating hand wheel 511 is arranged on the upper end of the vertical screw rod 510. In this embodiment, the vertical screw rod 510 is rotated to drive all the ring-shaped adjusting seats 507 to move vertically synchronously. Thus, the annular inclined guide wall 508 drives the radial guide rod 503 to move along the radial direction of the ring-shaped adjusting seat 507. The radial guide rod 503 drives the guide wheel 505 to move through the guide wheel seat 504, so that the guide wheel 505 changes the inclination angle of the metal wire. At the same time, the connecting spring 506 elastically stores energy, so that the radial guide rod 503 always elastically abuts against the annular inclined guide wall 508.
