DETAILED DESCRIPTION

[0031] To make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0032] In the following description, "left", "right", "front", "back", "up", "down" are oriented with the perspective direction of the front view.

[0033] In some embodiments, referring to the drawings of the specification, Figures 1-7 A continuous feeding automobile sheet metal part drying device, comprising a rack 1 and at least one continuous feeding assembly 2;

[0034] The continuous feeding assembly 2 is connected in the inside of the rack 1, and the inside of the rack 1 is connected with an adjustable drying assembly 3 for adjusting the air volume of different positions;

[0035] The adjustable drying assembly 3 comprises a fan 31, an air tank 32 and an adjustable air outlet pipe assembly 33. The upper end of the rack 1 is fixedly connected with at least one group of fans 31. The inside of the rack 1 is fixedly connected with at least one group of air tanks 32. Each group of air tanks 32 is in communication with the air outlet of at least one group of fans 31. The bottom of the air tank 32 is connected from left to right with multiple groups of adjustable air outlet pipe assemblies 33.

[0036] When the automobile sheet metal part is conveyed from the right end to the inside of the rack 1 through the continuous feeding assembly 2, the fan 31 blows hot air from the air outlet into the air tank 32, and then blows the hot air from the adjustable air outlet pipe assembly 33 at the bottom of the air tank 32 to the automobile sheet metal part, thereby realizing the drying of the sheet metal part. By adjusting the air volume of the adjustable air outlet pipe assembly 33 at multiple different positions from right to left, the air force is gradually decreased from right to left, and the drying requirements at each stage are accurately matched, so as to maintain the surface coating of the automobile sheet metal part at an ideal drying rate. The internal moisture or solvent of the coating cannot effectively escape, thereby preventing the generation of air bubbles, pinholes and other defects in the coating structure, so as to ensure the flatness and excellent adhesion of the surface coating of the sheet metal part.

[0037] The adjustable air outlet pipe assembly 33 comprises an air outlet pipe 331, a connecting rod support assembly 332, a rotating plate 333 and a limiting assembly. The bottom of the air tank 32 is fixedly connected with the air outlet pipe 331. The lower end of the air outlet pipe 331 is rotatably connected with multiple groups of rotating plates 333. The outer side of each rotating plate 333 is connected with the connecting rod support assembly 332 and the limiting assembly.

[0038] The limiting assembly comprises a connecting plate 334, a limiting slot 335 and a limiting slide rod 336. A group of connecting plates 334 is limitingly and slidably connected between every two adjacent rotating plates 333.

The connecting plate 334 is provided with a limiting slot 335 for limiting the sliding of the limiting slide rod 336.

[0039] The connecting rod support assembly 332 comprises a first connecting rod 3321, a second connecting rod 3322, a third connecting rod 3323, a positioning pin 3324 and a hinged seat 3325. The outer side of each rotating plate 333 is fixedly connected with a positioning pin 3324. The outer side of each rotating plate 333 is rotatably connected with a third connecting rod 3323 and a second connecting rod 3322.

[0040] When adjusting the air volume, the rotating plate 333 is manually rotated in the direction of approaching each other (wind force decreases) or moving away from each other (wind force increases), and the rotating plate 333 drives the limiting slide bar 336 to move in the direction of approaching or moving away from each other under the limiting guide of the limiting groove 335. The connecting plate 334 moves in the direction of approaching or moving away from each other under the limiting guide of the rotating plate 333. When the rotating plate 333 is rotated in the direction of approaching or moving away from each other, the third connecting rod 3323 and the second connecting rod 3322 move closer to or away from each other around the hinge seat 3325. When the swivel plate 333 is in the direction of moving away from the swivel plate 333, the swivel plate 333 is in the direction of moving away from the swivel plate 333. At the same time, the third link 3323 and the second link 3322 drive the first link 3321 to rotate inward or outward through the hinge seat 3325. When the positioning pin 3324 contacts the inner wall of the first link 3321, the swivel plate 333 cannot continue to rotate in the direction of moving away from the swivel plate 333. That is, the air volume is maximum at this time. The third link 3323, the second link 3322 and the first link 3321 jointly provide stable support for the swivel plate 333, preventing the swivel plate 333 from shrinking inward or expanding outward during use.
