Description

Technical Field

[0001] The utility model belongs to the technical field of enameled wire production, and in particular relates to a device for spraying a buffer coating on the surface of an enameled wire. Background Art

[0002] The car refrigerator compressor will vibrate during operation, so the enameled wire inside it needs to have a certain mechanical strength to resist the impact and wear caused by the vibration. Therefore, when the enameled wire is produced, a layer of impact-resistant buffer layer needs to be sprayed on the outer layer of the enameled wire through a spraying device. The impact-resistant buffer layer can absorb vibration energy and provide a certain degree of protection for the enameled wire.

[0003] When spraying an impact-resistant buffer layer onto the surface of the enameled wire through a spraying device, since the nozzle on the spraying device can only spray the paint in one direction, and the enameled wire blocks part of the paint, this phenomenon can easily lead to uneven distribution of the paint sprayed onto the surface of the enameled wire, resulting in poor effect when spraying the paint onto the enameled wire.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0030] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0031] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0032] See also Figures 1-8 As shown, the utility model is a buffer coating spraying device for the surface of an enameled wire, comprising a spray box 1, a displacement component 2 is arranged inside the spray box 1, a connecting tool 3 and a spray component 4 are rotatably installed on the movable end of the displacement component 2, the input end of the connecting tool 3 is dynamically connected to the driving end of the displacement component 2, and the output end of the connecting tool 3 is dynamically connected to the spray component 4, so that the displacement component 2 drives the spray component 4 to move laterally while driving the spray component 4 to make a circular motion around the enameled wire, winding components 5 are arranged on both sides of the spray box 1, and a linkage component 6 is arranged between the winding component 5 and the displacement component 2.

[0033] When spraying the enameled wire, the winding ends of the winding assemblies 5 on both sides of the spray box 1 rotate and make the enameled wire move inside the spray box 1. At this time, the winding ends of the winding assemblies 5 drive the driving end of the displacement assembly 2 to rotate through the linkage assembly 6, so that the displacement assembly 2 drives the spray assembly 4 to move inside the spray box 1. At the same time, the displacement assembly 2 drives the spray assembly 4 to rotate through the connecting tooling 3 while moving, so that the spray assembly 4 can perform a circular motion around the enameled wire while spraying the surface of the enameled wire.

[0034] By setting up the connecting tooling 3, the displacement component 2 can drive the spray component 4 to move inside the spray box 1, and at the same time, it can drive the spray component 4 to move in a circular motion around the enameled wire, so that the spray component 4 can spray the enameled wire in all directions. This setting makes the paint sprayed onto the enameled wire by the spray component 4 more evenly distributed, so that the effect of the spraying operation on the enameled wire can be guaranteed.

[0035] In one embodiment, for the above-mentioned displacement assembly 2, the displacement assembly 2 includes a mounting plate 201, the mounting plate 201 is fixedly mounted on the top of the inner wall of the spray box 1, a reciprocating screw 202 is rotatably connected between the two mounting plates 201, a movable plate 203 is provided on the outer surface of the reciprocating screw 202, a guide rod 204 is fixedly connected between the two mounting plates 201, and the movable plate 203 is movably connected to the guide rod 204.

[0036] By driving the reciprocating screw 202, the reciprocating screw 202 can drive the movable plate 203 to move back and forth inside the spray box 1. At the same time, the moving speed of the movable plate 203 is faster than the moving speed of the enameled wire inside the spray box 1. This setting ensures that the spray component 4 will not form a threaded spray layer when spraying onto the moving enameled wire driven by the movable plate 203, so that the coating formed on the enameled wire is more uniform and the thickness of the coating can be guaranteed. When the movable plate 203 moves, the guide rod 204 can guide the movable plate 203, so that the stability of the movable plate 203 when moving can be guaranteed.

[0037] In addition, in specific applications, the outer surface of the reciprocating screw 202 is provided with two thread grooves with the same pitch and opposite rotation directions, and the two ends of the thread grooves are connected by a transition curve, and a slider is provided at the position where the movable plate 203 is connected to the reciprocating screw 202. The slider is located inside the thread groove. When working, the reciprocating screw 202 is rotated, so that the side of the thread groove pushes the slider placed in the thread groove to perform axial reciprocating motion, and the movable plate 203 is driven by the slider to achieve reciprocating movement.

[0038] In one embodiment, for the above-mentioned connecting tooling 3, the connecting tooling 3 includes a driving rod 301, the driving rod 301 is rotatably connected to the mounting plate 201, the driving rod 301 and the outer surface of the reciprocating screw 202 are fixedly connected with a connecting gear 302, the two connecting gears 302 are threaded together, a driving gear 303 is provided on one side of the movable plate 203, the driving gear 303 is fixedly connected to the inner wall with a driving bar 304, the outer surface of the driving rod 301 is provided with a driving groove 305 corresponding to the driving bar 304, the driving bar 304 is movably connected to the driving groove 305, and the outer surface of the driving gear 303 is meshed with a mounting gear 306.

[0039] When the reciprocating screw 202 rotates and drives the movable plate 203, the movable plate 203 can drive the driving gear 303 and the mounting gear 306 to move together, and the driving gear 303 drives the driving bar 304 to slide inside the driving groove 305. At the same time, the reciprocating screw 202 can drive the driving rod 301 to rotate through the two meshing connecting gears 302, so that the driving rod 301 drives the driving gear 303 to rotate through the driving groove 305 and the driving bar 304, so that the driving gear 303 can drive the mounting gear 306 to rotate on one side of the movable plate 203. The above arrangement allows the mounting gear 306 to rotate while moving horizontally, and the entire operation only needs to drive the reciprocating screw 202, and the entire operation has strong linkage.

[0040] In one embodiment, for the above-mentioned connecting tool 3, the connecting tool 3 also includes a T-ring 307, and the T-ring 307 is arranged on one side of the driving gear 303 and the mounting gear 306. The movable plate 203 is provided with a T-slot 308 corresponding to the T-ring 307, and the T-ring 307 is rotatably connected to the T-slot 308.

[0041] When the driving gear 303 and the mounting gear 306 rotate, they can drive the corresponding T-ring 307 to rotate inside the corresponding T-slot 308. The setting of the T-ring 307 and the T-slot 308 allows the two gears to rotate normally on the movable plate 203, and the stability of the two gears during rotation can be guaranteed.

[0042] In one embodiment, for the above-mentioned spray assembly 4, the spray assembly 4 includes a spray tube 401, the spray tube 401 is fixedly connected to the inner wall of the mounting gear 306, one end of the spray tube 401 is fixedly installed with a nozzle 402, the other end of the spray tube 401 is fixedly installed with a rotary joint 403, one end of the rotary joint 403 is fixedly installed with a transport tube 404, and a guide tube 405 is arranged inside the spray tube 401, the rotary joint 403 and the transport tube 404, the guide tube 405 is rotatably connected to the tube body of the spray tube 401, and the guide tube 405 is fixedly connected to the tube body of the transport tube 404.

[0043] By passing the enameled wire through the inside of the guide tube 405, the enameled wire can be concentric and coaxial with the mounting gear 306. When the mounting gear 306 rotates, it can drive the spray tube 401 to rotate, so that the nozzle 402 on the spray tube 401 can move in a circular motion with the mounting gear 306 as the axis and directly spray the paint onto the outer surface of the enameled wire. At the same time, the transport tube 404 is connected to the external barrel, and the setting of the rotary joint 403 ensures that the spray tube 401 will not drive the transport tube 404 to rotate when it rotates, so that the barrel can normally transport the paint to the inside of the rotating spray tube 401 through the transport tube 404.

[0044] In addition, in specific applications, the rotary joint 403 is connected to the spray pipe 401 and the transport pipe 404 through a connecting flange, so that the firmness of the transport pipe 404 and the spray pipe 401 after being connected together through the rotary joint 403 can be guaranteed, and a sealing groove and a sealing ring are provided at the connection between the guide pipe 405 and the spray pipe 401, so that the sealing of the connection between the two can be guaranteed when the spray pipe 401 rotates on the outer surface of the guide pipe 405. At the same time, due to the hollow setting of the interior of the rotary joint 403, the guide pipe 405 will not affect the overall flow conductivity of the rotary joint 403 when passing through the interior of the rotary joint 403. At the same time, the part of the transport pipe 404 used to support the guide pipe 405 is rigidly set, and the transport pipe 404 on the upper side of the guide pipe 405 is made of a hose. This setting enables the transport pipe 404 to better support the guide pipe 405. At the same time, the hose part of the transport pipe 404 enables the movable plate 203 to normally drive the transport pipe 404 to reciprocate.

[0045] In one embodiment, for the above-mentioned winding assembly 5, the winding assembly 5 includes a support frame 501, the inner wall of the support frame 501 is rotatably connected to a rotating shaft 502, the outer surface of the rotating shaft 502 is provided with a winding disk 503, and a motor 504 is fixedly installed on one side of the support frame 501, and the output end of the motor 504 is fixedly connected to the rotating shaft 502.

[0046] The rotating shaft 502 is driven by the motor 504, and the rotating shaft 502 drives the winding reel 503 to rotate. At this time, the winding reels 503 on both sides of the spray box 1 rotate synchronously, so that one of the winding reels 503 can release the enameled wire, and the other winding reel 503 can reel in the enameled wire that has completed the spraying operation, so that the enameled wire can automatically move inside the spray box 1.

[0047] In one embodiment, for the above-mentioned linkage assembly 6, the linkage assembly 6 includes a linkage rod 601, the linkage rod 601 is rotatably connected to the spray box 1, the linkage rod 601 and the outer surface of the reciprocating screw 202 are fixedly connected with a bevel gear 602, the two bevel gears 602 are meshed together, the linkage rod 601 and the outer surface of the rotating shaft 502 are fixedly connected with a sprocket 603, and the outer surface of the sprocket 603 is meshed with a chain 604.

[0048] When the rotating shaft 502 drives the winding disk 503 to rotate, the rotating shaft 502 can drive the linkage rod 601 to rotate through the sprocket 603 and the chain 604, so that the linkage rod 601 drives the reciprocating screw 202 to rotate through two meshed bevel gears 602. This setting allows the rotation speeds of the rotating shaft 502 and the reciprocating screw 202 to be linked together, so that when the rotation speed of the winding disk 503 changes and the moving speed of the enameled wire changes, the moving speed of the movable plate 203 will also change under the drive of the reciprocating screw 202, so that the effect of the spraying component 4 when spraying the enameled wire can also be guaranteed.

[0049] In one embodiment, for the above-mentioned spray box 1 , wire holes 7 are opened on both sides of the spray box 1 , and heating plates 8 are fixedly installed on the inner wall of the spray box 1 corresponding to the wire holes 7 .

[0050] The enameled wire moves inside the spray box 1 through the wire hole 7. When the enameled wire inside the spray box 1 completes spraying and moves out of the spray box 1 through the wire hole 7, the heating plate 8 can heat and dry the spray layer on the enameled wire, so that the coating on the surface of the enameled wire will not be damaged when the winding reel 503 winds up the enameled wire.

[0051] According to the above technical solution, 1. by setting the connecting fixture 3, the displacement component 2 drives the spray component 4 to move inside the spray box 1, and at the same time, the spray component 4 can be driven to move in a circular motion around the enameled wire, so that the spray component 4 can spray the enameled wire in an all-round manner. This setting makes the paint sprayed by the spray component 4 on the enameled wire more evenly distributed, so that the effect of spraying the enameled wire can be guaranteed; 2. The rotating shaft 502 is connected to the reciprocating screw 202 through the sprocket 603, the chain 604, the linkage rod 601 and the two meshing bevel gears 602. At the same time, the reciprocating screw 202 is connected to the driving rod 301 through two meshing connecting gears 302, so that when the rotating shaft 502 drives the winding disk 503 to rotate and the moving speed of the enameled wire inside the spray box 1 changes, the moving speed of the moving plate 203 driven by the reciprocating screw 202 and the rotation speed of the driving gear 303 driven by the driving rod 301 and the mounting gear 306 can change together, so that no matter how the moving speed of the enameled wire changes, the distribution of the paint sprayed onto the enameled wire by the nozzle 402 on the spray tube 401 can always be kept uniform.
