Description

Technical Field

[0001] The invention relates to the technical field of copper wire processing, in particular to a coating device for copper wire drawing. Background Art

[0002] Copper is widely used in cables, electrical and electronic components due to its good ductility, good electrical and thermal conductivity. When copper is made into cables, it can be made into copper wires with different wire diameters by drawing according to the size of the designed current, and the surface of the copper wire can be painted after drawing to make enameled wire.

[0003] The copper wire needs to be painted and dried many times before the thickness of the paint skin wrapped on the outside of the copper wire reaches the required thickness. Since the surface painting of the copper wire is done by manual brushing, there will be a large difference in the thickness of each painting, and the amount of paint waste will be large. In order to solve the above technical problems, the existing patent application No. 202310365135.7 discloses a cable copper wire drawing device and a wire drawing method. The device can twist the threaded tube according to the thickness of the drawn copper wire, and one end of the appropriate closing tube is reduced, and the movable tube can be driven to move, so that the paint roller is close to or away from the copper wire. At the same time, it will also drive the telescopic tube to expand and contract, so as to change the length of the telescopic tube inserted into the liquid storage box, so as to change the number of oil inlet holes in the liquid storage box, and the amount of paint can be changed according to the wire diameter of the copper wire. However, in the above-mentioned prior art, during the repeated painting of the copper wire, the dust attached to the surface of the enameled wire and the dust in the environment will also enter the inside of the rotating tube, affecting the painting effect of the enameled wire and having a greater impact on the insulation performance of the paint layer.

[0050] like Figures 1 to 6 As shown, a copper wire drawing painting device includes a support seat 1, and the copper wire drawing painting device also includes:

[0051] The two half-enclosures 7 are detachably mounted on the top of the support seat 1 , and the two half-enclosures 7 enclose and form a sealed painting area.

[0052] The driving part 2 is used to drive the two semi-enclosures 7 to open and close. The driving part 2 includes a screw rod 21 rotatably arranged in the support seat 1, and two support blocks 23 are arranged on the outer side of the screw rod 21 relative to the threaded sleeve, and a driving motor 22 is used to drive the screw rod 21 to rotate. The bottom of the semi-enclosure 7 is fixed on the top of the support block 23. The driving motor 22 can drive the screw rod 21 to rotate, so as to drive the two support blocks 23 and the two semi-enclosures 7 to close to each other or open away from each other, so that the painting operation can be completed in a relatively sealed painting area to prevent external dust and impurities from affecting the painting quality. When the cleaning effect or painting effect deteriorates, the two semi-enclosures 7 in the closed state can be opened to facilitate inspection or maintenance.

[0053] A painting section 4 for painting is provided in the sealing area.

[0054] A support portion 3 is provided in the sealing area for supporting a painted portion 4.

[0055] The support part 3 comprises:

[0056] A fixing ring 31 is fixedly mounted on the supporting base 1 .

[0057] The gear ring 32 is fixedly sleeved on the fixing ring 31 .

[0058] A sliding seat 33 is slidably disposed in the gear ring 32 .

[0059] like Figures 2 to 6 As shown, the support portion 3 also includes:

[0060] A support ring 34 is fixedly arranged between the sliding seat 33 and the outer portion of the gear ring 32 .

[0061] The driving member 35 is arranged between the support ring 34 and the gear ring 32. The driving member 35 includes at least three gears circumferentially rotated on the support ring 34, and a servo motor is used to drive one of the gears to rotate. The tooth surface of the gear is meshed with the tooth surface of the gear ring 32. The driving member 35 is used to drive the support ring 34 to rotate.

[0062] The first support arm 36 is fixedly mounted on the support ring 34 .

[0063] A paint barrel 37 is fixedly mounted on the first support arm 36 away from the support ring 34. The first support arm 36 and the paint barrel 37 rotate synchronously with the support ring 34.

[0064] The dryer 38 is fixed on the sliding seat 33 and can dry the copper wire or enameled wire passing through the gear ring 32 to keep the surface of the copper wire or enameled wire dry and prevent water vapor from affecting the uniformity or quality of subsequent painting.

[0065] The painting section 4 includes:

[0066] A T-shaped bracket 41 is fixedly arranged on the top of the fixing ring 31 .

[0067] A paint can 43 for containing paint is arranged on the top of the T-shaped bracket 41 .

[0068] A supply pump 42 is provided in the paint tank 43 for pumping paint.

[0069] A plurality of paint absorbing media 47 are detachably mounted in the paint barrel 37 in the circumferential direction.

[0070] A paint tap 46 is slidably connected to an annular groove 48 provided between the outside and the inside of the paint barrel 37 .

[0071] A delivery pipe 45 is provided between the paint tap 46 and the supply pump 42 .

[0072] An extension rod 44 is fixedly mounted on the T-shaped bracket 41 and is used to fix and support the delivery pipe 45 .

[0073] With such a design, the prepared paint can be first added to the paint tank 43, and then the supply pump 42 is started to supply paint to the paint outlet faucet 46. As the paint cylinder 37 rotates, the paint outlet faucet 46 can evenly add paint to the paint absorbing medium 47 in a circumferential direction, so that there is always sufficient paint on the paint absorbing medium 47, avoiding changes in the paint thickness on the surface of the copper wire or the enameled wire, and maintaining the stability and uniformity of the paint thickness of the paint absorbing medium 47 on the surface of the copper wire or the enameled wire for a long time.

[0074] like Figures 3 to 6As shown, the support portion 3 includes a cleaning member 39 fixed on the support ring 34, and the cleaning member 39 is used to clean dust and impurities on the surface of the copper wire.

[0075] The cleaning member 39 includes a second support arm 391 fixedly mounted on the support ring 34 , a cleaning cylinder 392 on the second support arm 391 away from one end of the support ring 34 , and a plurality of cleaning brushes 393 are detachably mounted in the inner circumference of the cleaning cylinder 392 .

[0076] The first support arm 36 and the second support arm 391 are disposed opposite to each other on the support ring 34 , and ends of the first support arm 36 and the second support arm 391 away from the support ring 34 are both close to the axis of the support ring 34 .

[0077] The paint coating cylinder 37 and the cleaning cylinder 392 are relatively located on two sides of the outside of the fixing ring 31, and the paint coating cylinder 37, the cleaning cylinder 392 and the semi-sealed cylinder 7 are in a coaxial relationship.

[0078] With such a design, the copper wire or enameled wire can be threaded along the axis of the semi-enclosed cylinder 7 so that the copper wire or enameled wire coincides with its axis, so as to improve the uniformity of the paint during subsequent painting, and be able to comprehensively clean the surface of the copper wire or enameled wire in the circumferential direction. When the cleaning effect of the cleaning brush 393 decreases, it can be quickly disassembled for cleaning or replaced, thereby reducing the impact of the cleaning or replacement operation of the cleaning brush 393 on the painting efficiency.

[0079] like Figure 1 and Figure 2 As shown, the copper wire drawing painting equipment also includes reserved grooves 6 respectively arranged on the opposite surfaces of two half-enclosures 7, a semicircular hole 8 is arranged on the end surface of the half-enclosure 7, and a half-enclosure ring 5 is fixedly arranged in the half-enclosure 7.

[0080] The reserved groove 6 matches the vertical section of the T-shaped bracket 41 , and the closed interiors of the two half sealing rings 5 ​​match the exterior of the fixing ring 31 .

[0081] The closed interior of the two semicircular holes 8 matches the exterior of the paint cylinder 37 , and the semicircular holes 8 and the semi-enclosed cylinder 7 are in a coaxial relationship.

[0082] Such a design enables the cleaning brush 393, the gear ring 32, the support ring 34, the paint absorbing medium 47 and the semi-enclosed tube 7 to be coaxial, thereby ensuring that the copper wire or enameled wire always coincides with the axis of the cleaning brush 393 and the paint absorbing medium 47 during threading and transportation, thereby reducing the error range of the paint layer thickness and improving the uniformity of paint coating.

[0083] Working principle: before painting, the copper wire or the enameled wire that has not been painted is first axially passed through several cleaning brushes 393, the inside of the support ring 34 and several paint absorbing media 47 in sequence, and then the driving part 2 is controlled to drive the two half-enclosed cylinders 7 to approach each other until they are closed. At this time, the inner walls of the semicircular holes 8 on the two end faces of the half-enclosed cylinder 7 are respectively attached to the outer surfaces of the cleaning cylinder 392 and the paint cylinder 37, and the inner wall of the half-enclosed ring 5 is attached to the outer surface of the fixed ring 31, so that the two half-enclosed cylinders 7 are surrounded and formed to form a relatively sealed painting area, and the driving part 35 is started to drive the support ring 34 to rotate and synchronously drive the cleaning brush 393 and the paint absorbing medium 47 to rotate, so that the outer surface of the copper wire or enameled wire is cleaned before entering the painting area, and then the dryer 38 is used to dry the outer surface of the copper wire or enameled wire to avoid water vapor adhering to the surface of the copper wire or enameled wire affecting the subsequent uniformity and effect of painting, and finally the copper wire passes through the paint absorbing medium 47 and the copper wire Or when the enameled wire passes through the paint absorbing medium 47, the paint absorbing medium 47 will evenly and comprehensively apply the paint to the copper wire or the enameled wire, avoiding the problem of missing the copper wire or the enameled wire when cleaning or painting. Since the paint cylinder 37 rotates with the support ring 34, the paint tap 46 forms a relative rotation with the paint cylinder 37 in the annular groove 48, so that the supply pump 42 can continuously supply paint to the paint absorbing medium 47 through the paint tap 46, so that the paint absorbing medium 47 can continuously paint the surface of the copper wire or the enameled wire, thereby improving the uniformity and comprehensiveness of the painting. In addition, during the long-term painting process, when the painting effect of the paint absorbing medium 47 changes, the paint absorbing medium 47 can be disassembled, cleaned or replaced in a timely and rapid manner, or when the cleaning effect of the cleaning brush 393 deteriorates, the cleaning brush 393 can be disassembled, cleaned or replaced in a timely and rapid manner, thereby improving the cleaning or replacement efficiency of the paint absorbing medium 47 and the cleaning brush 393, and reducing the impact of the cleaning or replacement of the two on the painting efficiency.
