Technical Field

[0001] The utility model belongs to the technical field of powder spraying equipment, in particular to automatic powder spraying equipment used for processing metal front covers. Background Art

[0002] Powder spraying is the process of spraying powder coating onto the surface of a workpiece using a powder spraying device. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating which will be cured after high-temperature baking to form the final coating.

[0003] When powder spraying the metal front cover, a group of lifting mechanisms are usually used to transport the metal front cover, and the metal front cover in transportation is sprayed by automatic powder spraying equipment. When the automatic powder spraying device is spraying the metal front cover, it usually reciprocates up and down to make the spraying more uniform. Since the sizes of metal front covers of different products are different, the automatic powder spraying device in the prior art has a fixed up and down movement amplitude, so when powder spraying metal front covers of different sizes, it is difficult to control the range of powder spraying.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4 As shown, the utility model provides an automatic powder spraying device for metal front cover processing, including a mounting platform 1 and a connecting frame 5, a fixing rod 2 is installed inside the mounting platform 1, and a powder spraying head 3 is sleeved on the outer surface of the fixing rod 2, and also includes:

[0021] A reciprocating member, which is arranged on the mounting platform 1 and is used to control the reciprocating motion of the powder spraying head 3;

[0022] Among them, the reciprocating mechanism includes a connecting plate 4, which is installed on one side of the powder spray head 3, a movable frame 6 is hinged on the outer side of the connecting frame 5, a fixed shaft 12 is installed inside the movable frame 6, the outer surface of the fixed shaft 12 is sleeved with a second spring 13 and a round shaft 14, a slide groove 15 is provided on one side of the movable frame 6, and also includes a fixed frame 7, the fixed frame 7 is arranged on one side of the mounting platform 1, a first motor 8 is installed on the outer side of the fixed frame 7, a cam 9 is installed on the output shaft of the first motor 8, a cavity 10 is provided on one side of the mounting platform 1, a first spring 11 is sleeved inside the cavity 10, a second motor 17 is installed inside the mounting platform 1, a slot 16 is provided on the outer side of the mounting platform 1, a movable shaft 19 is sleeved inside the slot 16, and a threaded rod 18 is installed on the output shaft of the second motor 17.

[0023] The operation of the first motor 8 will cause the cam 9 to rotate, so that the cooperation between the cam 9 and the round shaft 14 can drive the movable frame 6 to rotate along the outer surface of the movable shaft 19. When the cam 9 is separated from the round shaft 14, the elastic force of the first spring 11 will drive the movable frame 6 to reset through the round shaft 14. The rotation of the movable frame 6 will drive the connecting plate 4 through the connecting frame 5 to make the powder spray head 3 reciprocate up and down. At the same time, the operation of the second motor 17 will cause the threaded rod 18 to rotate, so that the cooperation between the threaded rod 18 and the movable shaft 19 can drive the movable shaft 19 to move along the outer surface of the slot 16. By controlling the axis of rotation of the movable frame 6, the amplitude of the reciprocating motion of the powder spray head 3 can be adjusted.

[0024] The threaded rod 18 is threadedly connected to the movable shaft 19 , and the movable shaft 19 is slidingly matched with the sliding groove 15 .

[0025] The threaded rod 18 cooperates with the movable shaft 19 to drive the movable shaft 19 to move left and right along the inner side of the notch 16 , so that the movable frame 6 can be driven to tilt downward through the cooperation between the movable shaft 19 and the slide slot 15 , thereby controlling the amplitude of the reciprocating motion of the powder spray head 3 .

[0026] The second spring 13 is elastically supported between the round shaft 14 and the movable frame 6 .

[0027] The design of the second spring 13 allows the second spring 13 to have good elastic reset performance. At this time, since the second spring 13 is in a compressed state, an elastic force is applied to the round shaft 14. When the round shaft 14 moves along the inner side of the cavity 10, the round shaft 14 will move along the outer surface of the fixed shaft 12. At the same time, the second spring 13 can facilitate the reset of the round shaft 14.

[0028] The round shaft 14 is slidably matched with the cavity 10 , and the first spring 11 is elastically supported between the cavity 10 and the round shaft 14 .

[0029] Through the design of the first spring 11, the round shaft 14 has good elastic reset performance. At this time, since the first spring 11 is in a compressed state, it will apply an elastic force to the round shaft 14, so that when the cam 9 releases the squeeze on the round shaft 14, the first spring 11 will drive the round shaft 14 to reset.

[0030] The cam 9 is in compression contact with the circular shaft 14 .

[0031] Through the cooperation between the cam 9 and the round shaft 14, when the cam 9 squeezes the round shaft 14, the round shaft 14 will drive the movable frame 6 to rotate, so as to drive the powder spray head 3 to rotate through the connecting plate 4, and then drive the powder spray head 3 to move up and down, so that it can spray the metal front cover more evenly.

[0032] The working principle and use process of this utility model:

[0033] First, the operation of the second motor 17 will cause the threaded rod 18 to rotate, so that the cooperation between the threaded rod 18 and the movable shaft 19 can drive the movable shaft 19 to move along the outer surface of the slot 16, and the axis of rotation of the movable frame 6 is controlled. Then, the operation of the first motor 8 will cause the cam 9 to rotate, so that the cooperation between the cam 9 and the round shaft 14 can drive the movable frame 6 to rotate along the outer surface of the movable shaft 19. When the cam 9 is separated from the round shaft 14, the elastic force of the first spring 11 will drive the movable frame 6 to reset through the round shaft 14. Through the rotation of the movable frame 6, the connecting plate 4 will be driven by the connecting frame 5 to make the powder spray head 3 reciprocate up and down, thereby adjusting the amplitude of the reciprocating motion of the powder spray head 3.
