Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to a bare copper wire coating spraying machine. Background Art

[0002] Bare copper wire is a wire used for outdoor overhead power lines. Currently, when insulating bare copper wire, it is usually done by spraying insulating material onto the surface of the bare copper wire with a sprayer. The sprayer is a special coating equipment that uses spraying technology. It can control the airflow to instantly push the air distribution reversing device to reverse, so that the piston of the pneumatic motor can make a stable and continuous reciprocating motion, pressurize the inhaled paint, and transport the paint to the spray gun of the sprayer through a high-pressure hose, and the spray gun releases the paint onto the surface of the object to be coated.

[0003] For example, the patent with announcement number CN212284555U: an overhead bare wire insulation spraying device, including a spraying box, an overhead bare wire, the spraying box is composed of a box body and a cover body bolted to the top of the box body, the overhead bare wire is arranged through the box body through the inlet slot provided on the box body, a concave frame is welded on the top of the cover body, and the interior of the concave frame is rotatably connected to a running wheel through a first rotating shaft. In the above patent, the overhead bare wire insulation spraying device is a box-type structure as a whole, and the nozzle is arranged in the box body, which can prevent the external wind from affecting the nozzle, and improve the stability of the overhead bare wire spraying insulating paint. Secondly, a dust cleaning seat is also arranged in the box body, and an arc frame is arranged on the dust cleaning seat, and a dust cleaning brush is arranged in the arc frame.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to solve the technical problem that it is difficult to achieve a good cleaning effect for some adhered impurities when cleaning the copper wire surface with a brush in the current equipment, such as Figure 1-Figure 13 As shown, the following preferred technical solutions are provided: The bare copper wire coating spraying machine comprises a machine body 1 and two coating barrels 2 symmetrically fixedly mounted inside the machine body 1. A bracket 3 is fixedly connected to the top surface of the machine body 1. A coating assembly 4 is fixedly connected to the bracket 3. Both coating barrels 2 are connected to the coating assembly 4 through a pipeline 5. The coating inside the coating barrel 2 is pressurized so that the coating enters the coating assembly 4 through the pipeline 5. A cleaning assembly 6 and a rolling assembly 7 are rotatably arranged inside the coating assembly 4. The cleaning assembly 6 is used to clean impurities and dust adhering to the surface of the bare copper wire before spraying. The rolling assembly 7 is used to roll the coating during spraying. A drying component 8 is fixedly connected to one end of the inner wall of the body 4 for quickly air-drying the surface of the insulating coating after spraying. A driving motor 9 is fixedly installed on the bracket 3. A transmission component 10 is fixedly connected to one end of the output shaft of the driving motor 9. The transmission component 10 is respectively meshed with the cleaning component 6 and the rolling component 7. The transmission component 10 is connected to the drying component 8 through a chain 20, so that the cleaning component 6, the rolling component 7 and the drying component 8 can be driven by the driving motor 9. Walking components 30 are symmetrically fixedly connected at both ends of the top surface of the body 1 for driving the sprayer to move along the bare copper wire to be sprayed.

[0022] Before spraying, first load the paint barrel 2 into the machine body 1, and connect the paint barrel 2 to the spray assembly 4 through the pipe 5, and then hang the walking assembly 30 of the sprayer to the bare copper wire to be sprayed, start the walking assembly 30 to drive the sprayer to move along the bare copper wire, and at the same time drive the cleaning assembly 6 to rotate and move by the driving motor 9 to clean the impurities on the surface of the bare copper wire to prevent them from being wrapped into the coating and causing damage to the coating. As the machine body 1 moves, the cleaned bare copper wire enters the spray assembly 4. At this time, the paint inside the paint barrel 2 is pressurized, and the paint enters the spray assembly 4 through the pipe 5 and is sprayed out to spray the surface of the bare copper wire. It should be noted that the walking assembly 30 is driven by a separate motor not shown in the figure. It is a prior art and will not be repeated here.

[0023] During spraying, the driving motor 9 and the transmission assembly 10 can drive the rolling assembly 7 to rotate, and the insulating layer sprayed on the surface of the bare copper wire is rolled, so that the insulating coating can be evenly coated on the surface of the bare copper wire, avoiding excessive thickness of the insulating coating in the spraying intersection area, which affects the transmission efficiency of the copper wire.

[0024] After spraying, as the machine body 1 moves, the copper wire coated with the insulating coating reaches the drying component 8 at the outlet of the spraying component 4. The drying component 8 is driven to rotate by the driving motor 9, so that the gas can be sucked into the drying component 8 and blown evenly to the surface of the copper wire, thereby accelerating the curing speed of the insulating coating on the surface of the copper wire, reducing the fluidity of the coating, and avoiding the problem of the insulating coating being scratched by external debris before curing, resulting in local excessive thinning.

[0025] The walking assembly 30 includes a connecting frame 301 symmetrically fixedly connected to the top surface of the body 1, and a U-shaped piece 302 is fixedly connected to the top surface of each connecting frame 301. A supporting wheel 303 is rotatably connected to the inner wall of each U-shaped piece 302 for supporting the copper wire from the bottom. A slider 304 is symmetrically penetrated and slidably connected to the side wall of each U-shaped piece 302, and a vertical plate 305 is fixedly connected to one end of each slider 304. A walking wheel 306 is rotatably connected to the side wall of each vertical plate 305. The two walking wheels 306 can move closer to or away from each other under the drive of the slider 304. When the two walking wheels 306 are fully fitted, a wheel groove is formed, which works together with the supporting wheel 303 to press the copper wire tightly, thereby making the entire sprayer hanging line stable.

[0026] The other end of each slider 304 is fixedly connected to an electromagnet 3041, one end of one walking wheel 306 is fixedly provided with a driving key 3061, and one end of the other walking wheel 306 is provided with a key slot 3062 corresponding to the position of the driving key 3061. The two electromagnets 3041 have different polarities after being energized, so that the two walking wheels 306 can be moved closer to each other by driving the slider 304, and the two walking wheels 306 can fit together after the driving key 3061 is inserted into the key slot 3062.

[0027] The transmission assembly 10 includes a first rotating shaft 101 fixedly connected to one end of the output shaft of the driving motor 9, and a first transmission gear 102 is fixedly connected to the end of the first rotating shaft 101 away from the driving motor 9. The first transmission gear 102 is arranged corresponding to the cleaning assembly 6, so that the driving motor 9 can drive the cleaning assembly 6 to rotate after being turned on. A second transmission gear 103 is fixedly connected to the middle of the side wall of the first rotating shaft 101, and the second transmission gear 103 is arranged corresponding to the rolling assembly 7, so that the driving motor 9 can drive the rolling assembly 7 to rotate after being turned on. A first sprocket 104 is fixedly connected to the side wall of the end of the first rotating shaft 101 close to the driving motor 9, and the first sprocket 104 is arranged corresponding to the drying assembly 8.

[0028] The spraying assembly 4 includes a protective shell 41 fixedly connected to the top surface of the bracket 3, which is used for shielding during spraying to prevent paint from splashing everywhere. The first arc groove 411 and the second arc groove 412 are respectively provided at both ends of the inner wall of the protective shell 41, which are used to install the cleaning assembly 6 and the rolling assembly 7 respectively. A plurality of nozzles 42 are symmetrically penetrated and fixedly connected on the side wall of the protective shell 41. Each nozzle 42 is connected to the inside of the paint barrel 2 through a pipe 5. By pressurizing the paint inside the paint barrel 2, the paint can enter the nozzle 42 through the pipe 5 and be sprayed out. By setting a plurality of nozzles 42, the surface of the bare copper wire can be sprayed from different angles.

[0029] The cleaning assembly 6 includes a first inner gear ring 61, which is meshedly connected to the first transmission gear 102, so that the first inner gear ring 61 can be driven to rotate by the driving motor 9. A first limiting protrusion 611 is fixedly arranged on the outer ring side wall of the first inner gear ring 61, and the first limiting protrusion 611 is slidably arranged in the first arc groove 411. Through the arrangement of the first limiting protrusion 611 and the first arc groove 411, the first inner gear ring 61 is positioned and will not interfere with its rotation. A plurality of cleaning rods 62 are fixedly connected to the end face of the first inner gear ring 61, and the plurality of cleaning rods 62 are symmetrically arranged on the left and right, so that the bare copper wire can be inserted from above.

[0030] Each cleaning rod 62 includes a rod body 621, and a pointed head 622 is fixedly provided at one end of each rod body 621, and impurities adhering to the surface of the bare copper wire are removed by the pointed head 622. A cleaning brush 623 is fixedly provided on the side wall of each rod body 621 near one end of the pointed head 622, and the cleaning brush 623 is used to further clean the fine impurities remaining on the surface of the bare copper wire.

[0031] Specifically, when in use, the paint cartridge 2 is loaded into the machine body 1 and connected to the nozzle 42 through the pipe 5, and then the bare copper wire is passed between the two walking wheels 306 above the walking assembly 30 and supported by the supporting wheel 303, and then the two electromagnets 3041 are energized to attract each other, driving the two sliders 304 to slide close to each other, and then the driving key 3061 is stuck in the key slot 3062, completing the wire hanging operation, and after the sprayer is started, it moves along the bare copper wire through the walking wheel 306; before the bare copper wire is sprayed, Under the meshing action of the moving gear 102 and the first inner gear ring 61, the driving motor 9 can drive the first inner gear ring 61 to rotate, and then drive the rod body 621 and its connected pointed head 622 and cleaning brush 623 to rotate, and the impurities adhering to the surface of the bare copper wire are removed by the spiral propulsion of the pointed head 622, and then the remaining fine impurities are further cleaned by the cleaning brush 623 arranged behind the pointed head 622, so as to achieve a better cleaning effect and avoid the residual impurities from being wrapped into the insulating coating and causing damage to the coating.

[0032] In order to solve the technical problem that during the spraying operation, the sprayer usually uses multiple spray guns to spray the bare copper wire from different angles, which easily leads to excessive thickness of the spray in the cross-region and affects the transmission efficiency of the copper wire, such as Figure 3 and Fig. 9 As shown, the following preferred technical solutions are provided: The rolling assembly 7 includes a second inner gear ring 71, which is meshedly connected with the second transmission gear 103, so that the second inner gear ring 71 can be driven to rotate by the driving motor 9. A second limiting protrusion 711 is fixedly provided on the outer ring side wall of the second inner gear ring 71. The second limiting protrusion 711 is slidably set in the second arc groove 412 to position the second inner gear ring 71. A plurality of mounting frames 72 are fixedly connected to the end face of the second inner gear ring 71, and one end of each mounting frame 72 is rotatably connected to a roller 73. During spraying, the coating is rolled by the roller 73 so that the insulating coating is evenly coated.

[0033] Specifically, during spraying, multiple rollers 73 are arranged in a circular array around the outer wall of the bare copper wire with a certain gap. After the insulating coating is sprayed on the bare copper wire, as the machine body 1 moves, the rollers 73 move to the coating part. At this time, driven by the drive motor 9, the second inner gear ring 71 rotates, driving the multiple rollers 73 to contact the coating surface and roll it, so that the coating is evenly coated on the outer wall of the bare copper wire, avoiding a thick coating in the spray intersection area, which affects the transmission efficiency of the copper wire.

[0034] In order to solve the technical problem that after spraying, the coating surface is not completely cured, and the copper wire is easily scratched, which leads to the local insulation layer being too thin, increasing the risk of leakage, such as Figure 3 , Fig.10 and Fig.11 As shown, the following preferred technical solutions are provided: The drying component 8 includes an arc-shaped air chamber 81 symmetrically fixedly connected to the inner wall of the protective shell 41. A plurality of blowing holes 811 are provided on the inner arc surface of each arc-shaped air chamber 81. An air inlet mechanism 82 is fixedly connected to the side wall of each arc-shaped air chamber 81. The gas is sucked into the arc-shaped air chamber 81 through the air inlet mechanism 82 and is evenly blown out through the plurality of blowing holes 811, so as to quickly dry the insulating layer sprayed on the surface of the copper wire and accelerate the curing of the coating surface.

[0035] The air intake mechanism 82 includes an air intake pipe 821 that passes through and is fixedly connected to the side wall of the arc-shaped air chamber 81, a fixing frame 822 is fixedly connected to the inner wall of the air intake pipe 821, a second rotating shaft 823 passes through and is rotatably connected to the side wall of the fixing frame 822, one end of each second rotating shaft 823 is fixedly connected to a fan 824, and the other end of each second rotating shaft 823 is fixedly connected to a second sprocket 825, and the two second sprockets 825 are both connected to the first sprocket 104 through the chain 20. During operation, the driving motor 9 drives the fan 824 to rotate and absorb air through the transmission of the first sprocket 104, the second sprocket 825 and the chain 20.

[0036] Specifically, after the bare copper wire is sprayed and rolled, as the machine body 1 moves, the drying component 8 moves to the coating part. At this time, driven by the driving motor 9, the first sprocket 104 drives the two second sprockets 825 to rotate through the chain 20, and then drives the corresponding fan 824 to rotate and absorb air through the second rotating shaft 823, and the external air is sucked into the arc-shaped wind chamber 81. After diffusion, it is blown out from the inside of multiple blowing holes 811 at a certain flow rate to air-dry the sprayed coating surface, accelerate the curing speed of the copper wire insulation coating surface, reduce the fluidity of the coating, and at the same time avoid the problem of local excessive thinness of the insulation coating caused by scratches by external debris before curing.
