Technical Field
[0001] The present utility model relates to the field of painting, and specifically to a drying device for a painting line. Background Art
[0002] Painting not only requires to be uniform and smooth, but also needs to have good rust and corrosion prevention properties to extend the service life of products. Therefore, as a key link in the painting process, drying directly affects the final quality of the painted parts.
[0003] Many existing drying devices adopt a single heating method, such as electric heating drying or hot air drying, which is difficult to achieve uniform drying of multiple sides of the painted parts. This results in an unsatisfactory drying effect and easily causes problems such as uneven drying and local overheating. Content of the Utility Model
[0004] In order to overcome the above deficiencies, the present utility model provides a drying device for a painting line.
[0005] The technical solution adopted by the present utility model:
[0006] A drying device for a painting line includes a drying box, and the drying box is a cubic shell; the front and rear ends of the drying box are open, and heat insulation curtains are fixedly connected to the tops of the openings at the front and rear ends of the drying box. The heat insulation curtains hang downwards and cover the openings of the drying box. There is a support frame inside the drying box, and the top of the support frame is flush with the bottom of the opening of the drying box. A conveying mechanism is arranged on the top of the support frame. The inside of the drying box is divided into a front part, a middle part and a rear part. A number of electric heating tubes are fixedly connected to the inner walls of the front part and the middle part. The electric heating tubes are square, and the electric heating tubes surround the conveying mechanism. Air inlet pipes are respectively fixedly communicated with the tops of the front part and the middle part. The air inlet pipes are distributed in a rectangular array. A filter screen is fixedly connected to the top inner wall of the air inlet pipe. An air inlet fan is arranged inside the air inlet pipe. The lower part of the filter screen is the air inlet fan. Exhaust pipes distributed in a rectangular array are fixedly communicated with the top of the rear part. An exhaust fan is fixedly installed inside the exhaust pipes.
[0007] The conveying mechanism includes conveying rollers and connecting shafts. A number of conveying rollers are equidistantly distributed front and back. The connecting shafts are located between two conveying rollers. The upper part of the support frame is in the shape of a square frame. The left and right ends of the conveying rollers and the connecting shafts are respectively rotatably connected to the left and right inner side walls of the upper part of the support frame. The left end of the conveying roller penetrates through the support frame and is fixedly connected with a first gear. The left end of the connecting shaft penetrates through the support frame and is fixedly connected with a second gear. The second gear meshes with two adjacent first gears. A motor is fixedly installed on the front side of the top of the right side wall of the support frame. The output shaft of the motor is fixedly connected with the right end of the front conveying roller.
[0008] The beneficial effects of the present utility model:
[0009] By arranging the electric heating tubes around the conveying mechanism, the utility model realizes the three-dimensional drying of all four sides of the painted parts. Compared with the single-side or double-side drying method, the drying effect is more uniform and efficient. The heat generated by the electric heating tubes is combined with the cold air introduced by the intake fan to form a hot air circulation, which not only increases the drying temperature but also accelerates the volatilization of the solvent on the surface of the painted parts through air flow, significantly shortening the drying time.

Detailed Implementation Manner
[0016] As Figures 1-5 shown: A drying device for a painting line includes a drying box 1. The drying box 1 is a cubic housing with openings at the front and rear ends. Heat insulation curtains 2 are fixedly connected to the tops of the openings at the front and rear ends of the drying box 1, and the heat insulation curtains 2 hang downwards to cover the openings of the drying box 1. There is a support frame 3 inside the drying box 1, and the top of the support frame 3 is flush with the bottom of the opening of the drying box 1. A conveying mechanism is arranged on the top of the support frame 3. The inside of the drying box 1 is divided into a front part 15, a middle part 16, and a rear part 17. A plurality of electric heating tubes 9 are fixedly connected to the inner walls of the front part 15 and the middle part 16. The electric heating tubes 9 are square and surround the conveying mechanism. Intake pipes 10 are respectively and fixedly communicated with the tops of the front part 15 and the middle part 16. The intake pipes 10 are arranged in a rectangular array. A filter screen 11 is fixedly connected to the inner wall of the top of the intake pipes 10, and an intake fan 12 is arranged inside the intake pipes 10. The intake fan 12 is below the filter screen 11. Exhaust pipes 13 arranged in a rectangular array are fixedly communicated with the top of the rear part 17, and an exhaust fan 14 is fixedly installed inside the exhaust pipes 13.
[0017] The conveying mechanism includes conveying rollers 4 and a connecting shaft 5. A number of conveying rollers 4 are equidistantly distributed front and back. The connecting shaft 5 is located between two conveying rollers 4. The upper part of the support frame 3 is in the shape of a square. The left and right ends of the conveying rollers 4 and the connecting shaft 5 are respectively rotatably connected to the left and right inner side walls of the upper part of the support frame 3. The left end of the conveying roller 4 penetrates through the support frame 3 and is fixedly connected to a first gear 6. The left end of the connecting shaft 5 penetrates through the support frame 3 and is fixedly connected to a second gear 7. The second gear 7 meshes with two adjacent first gears 6. A motor 8 is fixedly installed on the front side of the top of the right side wall of the support frame 3. The output shaft of the motor 8 is fixedly connected to the right end of the front conveying roller 4.
[0018] Start the motor 8. The output shaft of the motor 8 drives the front conveying roller 4 to rotate. Due to the meshing effect of the connecting shaft 5, the first gear 6 and the second gear 7 between the conveying rollers 4, the synchronous rotation of all the conveying rollers 4 is realized, thus forming a continuous conveying mechanism.
[0019] The painted parts to be dried are placed on the conveying rollers 4. As the conveying rollers 4 rotate, the painted parts are smoothly conveyed forward and enter the drying box 1 through the front end opening of the drying box.
[0020] During the conveying process of the painted parts, they pass through the front and middle parts of the drying box 1. Electric heating tubes 9 are installed on the inner walls of these two parts. The electric heating tubes 9 are arranged around the conveying mechanism. The heat generated by the electric heating tubes 9 is used to heat the painted parts, promoting the rapid volatilization of the solvent in the paint.
[0021] At the same time, external air is introduced through the air inlet pipe 10 at the top of the front and middle parts of the drying box 1. The air inlet fan 12 inside the air inlet pipe 10 accelerates the air flow, sucks in the cold air and sends it into the drying box after being filtered by the filter screen 11. These hot air and the heat generated by the electric heating tubes 9 act together to form a hot air circulation, further accelerating the drying process of the painted parts.
[0022] The waste gas and excess heat generated during the drying process are discharged through the exhaust pipe 13 at the rear of the drying box 1. The exhaust fan 14 inside the exhaust pipe 13 enhances the exhaust efficiency of the waste gas, ensuring the air circulation and temperature control inside the drying box.
[0023] Driven by the conveying mechanism, after the painted parts complete the entire drying process, they are sent out from the rear end opening of the drying box 1. The present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present utility model.
