Description

Technical Field

[0001] The invention belongs to the technical field of enameled wire production, in particular to a paint baking and drying device for enameled wire production. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of a conductor and an insulating layer. The bare wire is annealed and softened, then painted and baked for multiple times. In the production process of enameled wire, the main purpose of baking is to fully cure the glue and completely adhere to the copper wire. In this process, the solvent and diluent will be evaporated, and the paint base will undergo a cross-linking and curing reaction. During the entire painting, baking and drying process, the baking furnace will produce organic waste gas caused by the processing of enameled wire. At the same time, the baking furnace needs to be sealed during the processing, baking and drying of the enameled wire to reduce the unorganized emission of organic waste gas.

[0003] At present, when the baking furnace is sealed to make it operate, the organic waste gas generated by the enameled wire will generate a large amount of organic waste gas to be purified in the baking furnace over time. The subsequent treatment of the organic waste gas requires a lot of time to purify the waste gas in the baking furnace to ensure the safety of the production environment. At the same time, when the copper wire passes through the baking furnace in sections, it is baked and dried by the high temperature in the baking furnace. However, the heating system of the baking furnace in the prior art has a large interval, and it is impossible to ensure that the air body passing through the heating system is completely heated, resulting in uneven temperature differences between the hot and cold air bodies, which affects the baking effect.

[0031] 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.

[0032] like Figures 1 to 8 As shown, the present invention provides a paint baking and drying device for enameled wire production, comprising a baking furnace 1, an exhaust pipe 11 is fixedly connected to one side of the top of the baking furnace 1, an air plug 12 is tightly clamped on the top of the exhaust pipe 11, and a plurality of wire inlet holes 13 are opened on both ends of the baking furnace 1, and further comprising:

[0033] The auxiliary heating part 2 includes a telescopic electric cylinder 21 fixedly connected to the outer wall of one end of the baking oven 1, and a plurality of meshing rotating structures are provided on one end of the telescopic electric cylinder 21, each of which is provided with a friction heating structure, and a purification structure is provided in the exhaust pipe 11;

[0034] The above scheme is adopted: by starting the telescopic electric cylinder 21 to drive the tooth plate 22 to move horizontally, so that the tooth plate 22 drives the meshing tooth cylinder 23 to rotate, and the rotating tooth cylinder 23 will synchronously drive the connected rotating cylinder 24 and metal cylinder 25 to rotate synchronously. The rotation of the metal cylinder 25 will definitely drive the multiple metal inclined plates 27 to rotate. When the rotating cylinder 24 rotates passively, the outer wall of the metal cylinder 25 will continue to rub against the multiple metal balls 232 repeatedly. The friction between the two metal materials will cause frictional heat, so that the temperature is higher than other parts outside the rotating cylinder 24. Through the inclined state of multiple metal inclined plates 27, the temperature in the baking furnace 1 and the metal cylinder 25 can be refracted to bake and dry the painted copper wire, which can accelerate the curing of the paint on the copper wire and avoid the problem of unstable baking effect.

[0035] When the tooth plate 22 moves horizontally, it will drive the arc frame plate 241 to move horizontally synchronously, so that the arc frame plate 241 will contact and press against the magnetic block 237, thereby driving the magnetic block 237 to move upward into the purification mesh disk 235 to attract four purification mesh plates 238, so that one end of the multiple purification mesh plates 238 contacts the magnetic block 237, and the multiple purification mesh plates 238 that move passively will be stretched to the spring 240 synchronously. The multiple correspondingly installed springs 240 will facilitate the subsequent reset of each purification mesh plate 238 and extend out of the purification mesh disk 235, thereby expanding the purification range of the organic waste gas generated in the baking oven 1.

[0036] One point that needs to be added is that when the arc frame plate 241 does not contact the magnetic block 237, the telescopic rod 234 will be driven downward by the weight of the purification network plate 235, so that the four purification network plates 238 are no longer limited by the exhaust pipe 11, but are driven by the correspondingly installed springs 240 to extend out of the purification network plate 235. The telescopic electric cylinder 21 is pre-programmed to perform horizontal intermittent reciprocating motion.

[0037] The meshing rotating structure includes a tooth plate 22 and four tooth cylinders 23 meshingly connected with the tooth plate 22. A rotating cylinder 24 is fixedly connected to the inner wall of each tooth cylinder 23. One end of the tooth plate 22 is fixedly connected to the telescopic electric cylinder 21.

[0038] Each meshing rotating structure further includes a metal cylinder 25 and a plurality of metal inclined plates 27 surrounding and fixedly connected to the inner wall of the metal cylinder 25. The outer walls at both ends of the metal cylinder 25 and the outer walls at both ends of the rotating cylinder 24 are jointly and fixedly connected with four positioning plates 26.

[0039] The above scheme is adopted: starting the telescopic electric cylinder 21 drives the tooth plate 22 to move horizontally, so that the tooth plate 22 drives the meshing gear cylinder 23 to rotate, and the rotating gear cylinder 23 will synchronously drive the connected rotating cylinder 24 to rotate. Therefore, the rotating cylinder 24 will also drive the metal cylinder 25 connected to it to rotate synchronously through the installation of multiple positioning plates 26, and then the rotation of the metal cylinder 25 will definitely drive the multiple fixed metal inclined plates 27 to rotate.

[0040] The friction heating structure includes arc grooves 28 that penetrate through the upper and lower ends of the rotating drum 24, and two groups of T-shaped arc grooves 29 are opened in the inner walls of both ends of the rotating drum 24. The inner walls of the two arc grooves 28 are fitted and slidably connected with rectangular blocks 230. One end of the two rectangular blocks 230 is fixedly connected with an arc panel 231. The inner walls of one end of the two arc panels 231 are movably sleeved with a plurality of metal balls 232. The two groups of metal balls 232 are fitted and slidably connected with the outer walls of the two ends of the metal drum 25. Two groups of T-shaped sliders 2901 are fixedly connected to the outer walls of one end of the two arc panels 231, and the two groups of T-shaped sliders 2901 are slidably engaged with the inner walls of the T-shaped arc grooves 29, and the outer walls of the two arc panels 231 are fitted with the inner walls of the rotating drum 24. A disk rod 233 is movably sleeved on one side of the telescopic electric cylinder 21, and the rod bodies at both ends of the disk rod 233 are respectively fixedly connected to the two groups of rectangular blocks 230, and the two ends of the disk rod 233 are also fixedly connected to the inner wall of one end of the baking oven 1.

[0041] The above scheme is adopted: when the rotating drum 24 is passively rotated, the outer wall of the metal cylinder 25 will continuously and repeatedly rub against the multiple metal balls 232 installed on the arc panel 231. The friction between the two metal materials will cause frictional heat, thereby causing local temperature rise in the baking furnace 1, and the temperature is higher than other parts outside the rotating drum 24. In addition, when the rotating drum 24 is rotating, the two T-shaped sliders 2901 and the rectangular block 230 installed on one end of the arc panel 231 will be limited and engaged in the corresponding T-shaped arc grooves 29 and arc grooves 28, thereby having a limited sliding effect on the rotating drum 24. After the metal cylinder 25 is heated by friction, the heat will be transmitted to the multiple metal inclined plates 27. Through the inclined state of the multiple metal inclined plates 27, the temperature in the baking furnace 1 and the metal cylinder 25 can be refracted to bake and dry the painted copper wire.

[0042] The purification structure includes a telescopic rod 234, the top of which is fixedly connected to the bottom of the air plug 12, a purification net disk 235 is fixedly connected to the bottom of the telescopic rod 234, a telescopic rod 236 is fixedly connected to the inner wall of the top of the purification net disk 235, and a magnetic block 237 is fixedly connected to the bottom of the telescopic rod 236. The four ends of the purification net disk 235 are all connected through and slidingly connected with purification net plates 238, one end of each of the four purification net plates 238 can be magnetically connected to the outer wall of the magnetic block 237, and an arc-shaped fence 239 is fixedly connected to the outer wall of the top side of each of the four purification net plates 238. The inner and outer walls of the bottom are slidably connected, and the outer walls of one end of the four arc-shaped baffles 239 and the inner wall of the purification mesh disk 235 are jointly fixedly connected with a spring 240. The outer walls of the purification mesh disk 235 and one end of the four purification mesh plates 238 can be fitted and slidably connected to the inner wall of the exhaust pipe 11. The bottom end of the magnetic block 237 can be fitted and slidably connected with the arc frame plate 241. The bottom end of the arc frame plate 241 is fixedly connected to the outer wall of one side of the top of the tooth plate 22. The metal cylinder 25, multiple metal inclined plates 27 and multiple metal balls 232 are all made of metal materials, and the ends of the four purification mesh plates 238 close to the magnetic block 237 are also made of metal.

[0043] The above scheme is adopted: when the tooth plate 22 moves horizontally, it will drive the arc frame plate 241 to move horizontally synchronously, thereby causing the arc frame plate 241 to contact and press against the magnetic block 237 to move upward into the purification mesh disk 235, and at the same time, it will squeeze the telescopic rod 236 in real time to cause it to shrink, and the magnetic block 237 will synchronously attract the four purification mesh plates 238, thereby the four purification mesh plates 238 will be synchronously driven into the purification mesh disk 235, and under the upward operation of the arc frame plate 241, the telescopic rod 1 234 will be driven to shrink and the purification mesh disk 235 will return to the exhaust pipe 11, and the multiple passively moved purification mesh plates 238 will be synchronously stretched to the spring 240 to cause it to deform, and the multiple correspondingly installed springs 240 will facilitate the subsequent reset of each purification mesh plate 238 and extend it out of the purification mesh disk 235, thereby expanding the purification range of the organic waste gas generated in the baking oven 1.

[0044] The working principle and use process of the present invention are as follows: the painted copper wire is passed through the wire inlet slots 13 and the metal cylinder 25 opened at both ends of the baking furnace 1, and then the baking furnace 1 is started to heat up the inside thereof. The heating system of the baking furnace 1 is a prior art and will not be described in detail herein. The tooth plate 22 is driven to move horizontally by starting the telescopic electric cylinder 21, so that the tooth plate 22 drives the meshing tooth cylinder 23 to rotate, and the rotating tooth cylinder 23 will synchronously drive the connected rotating cylinder 24 to rotate. Thus, the rotating cylinder 24 will also drive the metal cylinder 25 connected thereto to rotate synchronously through the installation of multiple positioning plates 26, and then the rotation of the metal cylinder 25 will inevitably drive the multiple fixedly installed metal inclined plates 27 to rotate. The installation arrangement of the metal cylinder 25 and the multiple metal inclined plates 27 in the baking furnace 1 can make both of them receive high temperature and be driven to generate heat themselves. At the same time, when the rotating cylinder 24 is passively When rotating, the outer wall of the metal cylinder 25 will continuously and repeatedly rub against the multiple metal balls 232 installed on the arc panel 231. The friction between the two metal materials will cause frictional heat, thereby causing local temperature rise in the baking furnace 1, which is higher than other parts outside the rotating drum 24. When the rotating drum 24 rotates, the two T-shaped sliders 2901 and the rectangular block 230 installed on one end of the arc panel 231 will be limited and engaged in the corresponding T-shaped arc grooves 29 and arc grooves 28, thereby having a limited sliding effect on the rotating drum 24. After the metal cylinder 25 is heated by friction, the heat will be transmitted to the multiple metal inclined plates 27. Through the inclined state of the multiple metal inclined plates 27, the temperature in the baking furnace 1 and the metal cylinder 25 can be refracted to bake and dry the painted copper wire, which can accelerate the curing of the paint on the copper wire and avoid the problem of unstable baking effect.

[0045] At the same time, when the tooth plate 22 moves horizontally, it will drive the arc frame plate 241 to move horizontally synchronously, so that the arc frame plate 241 will contact and press against the magnetic block 237, thereby driving the magnetic block 237 to move up and enter the purification network disk 235, and at the same time, it will squeeze the telescopic rod 236 in real time to cause it to shrink. The magnetic block 237 entering the purification network disk 235 will synchronously attract the four purification network plates 238, so that one end of the multiple purification network plates 238 is in contact with the magnetic block 237, thereby the four purification network plates 238 will be synchronously driven into the purification network disk 235, and on the arc surface When the rack 241 is pushed up, the telescopic rod 234 will be retracted and the purification mesh plate 235 will return to the exhaust pipe 11, and the multiple purification mesh plates 238 that are passively moved will be synchronously stretched to the spring 240 to cause it to deform. The multiple correspondingly installed springs 240 will facilitate the subsequent reset of each purification mesh plate 238 and extend out of the purification mesh plate 235, thereby expanding the purification range of the organic waste gas generated in the baking furnace 1. The above process also purifies the organic waste gas during the baking process of the enameled wire, avoiding the subsequent purification treatment of the waste gas separately, thereby improving the production and processing efficiency.
