The lifting assembly 5 is disposed on the base 1, and the lifting assembly 5 is used to drive the pressure plate assembly 4 to slide longitudinally, thereby enabling the pressure plate assembly 4 to slide towards or away from the base 3.

[0029] The base 3 has a roughly convex shape and includes a main body 31 and two connecting parts 32. The two connecting parts 32 are respectively located at opposite ends of the main body 31, and the height of the connecting part 32 is smaller than the height of the main body 31. A waist-shaped groove 321 is formed on the connecting part 32, penetrating the upper and lower end faces of the connecting part 32. The waist-shaped groove 321 allows for adjustment of the position of the base 3 relative to the mounting bracket 2. The mounting bracket 2 has a connecting groove (not shown) that mates with the waist-shaped groove 321. When the base 3 needs to be installed, it is first placed on the mounting bracket 2, and then bolts are threaded through the waist-shaped groove 321 and connected to the connecting groove, thereby fixing the base 3 relative to the mounting bracket 2.

[0030] A paint inlet hole 322 is provided on the side wall of the connecting part 32. The paint inlet hole 322 is connected to a paint pump, so that polyester paint can be introduced into the paint inlet hole 322 through the paint pump. Furthermore, there are two paint inlets 322, so that more polyester paint can be introduced into the paint inlet hole 322 in the same amount of time.

[0031] A through hole 311 is provided on the side wall of the main body 31, which communicates with the paint inlet hole 322, and the diameter of the through hole 311 is smaller than the diameter of the paint inlet hole 322. A paint storage tank 312 is formed by a downward recess on the upper end surface of the main body 31, and the paint storage tank 312 communicates with the through hole 311. Furthermore, a paint impregnation tank 313 is also formed by a downward recess on the upper end surface of the main body 31, located on one side of the paint storage tank 312, and communicating with the paint storage tank 312.

In this embodiment, the impregnation tank 313 has a triangular cross-section, and the bottom wall of the impregnation tank 313 is inclined. The height of the side of the impregnation tank 313 near the paint storage tank 312 is lower than the height of the side of the impregnation tank 313 away from the paint storage tank 312. This allows the polyester paint in the impregnation tank 313 and the paint storage tank 312 to rise slowly, and ensures that the polyester paint can be completely filled in the impregnation tank 313 and the paint storage tank 312. The upper surfaces of the polyester paint in the impregnation tank 313 and the paint storage tank 312 are on the same plane.

[0032] Furthermore, a groove 314 is provided on the upper surface of the main body 31 corresponding to the impregnation tank 313, and a lower felt (not shown) is also provided on the upper surface of the base 3. Specifically, the lower felt is located on the upper surface of the main body 31. The groove 314 is provided so that the lower felt can absorb more polyester paint.

[0033] The pressure plate assembly 4 includes a pressure plate 41 and a sealing plate 42. The sealing plate 42 covers the pressure plate 41 and is used to seal the pressure plate 41.

[0034] A paint supply hole 411 is provided on the side wall of the pressure plate 41. The paint supply hole 411 is connected to another paint pump, so that polyester paint can be introduced into the paint supply hole 411 through the other paint pump. Furthermore, there are two paint supply holes 411, so that polyester paint can enter into the paint supply holes 411 more quickly.

[0035] A flow hole 412 is formed by an inwardly recessed bottom wall of the paint supply hole 411, and the diameter of the flow hole 412 is smaller than the diameter of the paint supply hole 411. A paint storage groove 413 is formed by a downwardly recessed upper surface of the pressure plate 41, and the paint storage groove 413 is connected to the flow hole 412. Furthermore, a connecting groove 414 is also formed by a downwardly recessed lower surface of the upper surface of the pressure plate 41, and the connecting groove 414 is connected to the paint storage groove 413. The cross-section of the connecting groove 414 is triangular, and the height of the side of the connecting groove 414 closer to the paint storage groove 413 is higher than the height of the connecting groove 414 further away from the paint storage groove 413. A paint outlet hole 415 is formed by a downwardly recessed lower surface of the bottom wall of the paint outlet hole 415, and a paint drip hole 416 is formed by a downwardly recessed lower surface of the bottom wall of the paint outlet hole 415, and the diameter of the paint drip hole 416 is smaller than the diameter of the paint outlet hole 415.

[0036] Furthermore, an upper felt (not shown) is provided at the bottom of the pressure plate 41. In use, polyester paint dripping from the drip hole 416 falls onto the upper felt.

[0037] The lifting assembly 5 includes a bracket 51, a fixed frame 52, a drive motor 53, a lead screw 54, a guide rod 55, a slider 56, and a connecting frame 57. The bracket 51 is fixedly mounted on the base 1, the fixed frame 52 is fixedly mounted on the bracket 51, the drive motor 53 is fixedly mounted on the fixed frame 52, one end of the lead screw 54 is fixedly connected to the output shaft of the drive motor 53, and the other end of the lead screw 54 is rotatably connected to the fixed frame 52. The guide rod 55 is fixedly mounted on the fixed frame 52, the slider 56 is threaded onto the outside of the lead screw 54, and the slider 56 is slidably mounted onto the outside of the guide rod 55. The connecting frame 57 is fixedly mounted on the slider 56. In use, the drive motor 53 is started, which drives the lead screw 54 to rotate. This causes the slider 56 to slide up and down along the length of the lead screw 54 as the lead screw 54 rotates. The guide rod 55 limits the slider 56, preventing it from rotating along with the lead screw 54. This causes the connecting frame 57 to slide up and down, moving the upper felt closer to or away from the lower felt.

[0038] Furthermore, the fixing frame 52 includes a connecting part 521, a mounting part 522, a through part 523, and a fixing part 524. The connecting part 521 is fixedly connected to the bracket 51. The mounting part 522, the through part 523, and the fixing part 524 are all fixedly disposed on one side of the connecting part 521, and the mounting part 522, the through part 523, and the fixing part 524 are all located on the side of the connecting part 521 away from the bracket 51. The mounting part 522 is located at the top of the connecting part 521, the through part 523 is located in the middle of the connecting part 521, and the fixing part 524 is located at the bottom of the connecting part 521. The drive motor 53 is fixedly mounted on the mounting part 522. The output shaft of the drive motor 53 passes through the mounting part 522. One end of the lead screw 54 is fixedly connected to the output shaft of the drive motor 53. The other end of the lead screw 54 passes through the through part 523 and is rotatably connected to the fixed part 524. One end of the guide rod 55 is fixedly connected to the mounting part 522. The other end of the guide rod 55 passes through the through part 523 and is fixedly connected to the fixed part 524. The slider 56 is located between the through part 523 and the fixed part 524.

[0039] In use, the copper wire is first laid on the lower felt, and then the drive motor 53 is started, which drives the lead screw 54 to rotate. This causes the slider 56 to slide up and down along the length of the lead screw 54 as the lead screw 54 rotates. The guide rod 55 limits the slider 56, preventing it from rotating with the lead screw 54. This causes the connecting frame 57 to slide downward, bringing the upper felt closer to the lower felt until they are in contact, thus allowing for uniform coating of the copper wire.

[0040] This utility model also provides an enameling machine, which includes the above-mentioned painting device.

[0041] The painting device or enameling machine provided by this utility model has a pressure plate 41 with a dripping hole 416. The polyester paint dripping from the dripping hole 416 falls onto the upper felt, and the copper wire is located between the upper felt and the lower felt, so that the copper wire can be evenly coated with paint.

[0042] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
