Description

Technical Field

[0001] This utility model relates to the field of aluminum profile electrophoretic processing technology, specifically a drying device for aluminum profile electrophoretic coating. Background Technology

[0002] In the field of aluminum profile processing, electrophoretic coating is a widely used surface treatment technology that can endow aluminum profiles with good corrosion resistance, decorative properties, and wear resistance. The drying process after electrophoretic coating is crucial, directly affecting the quality and performance of the coating.

[0003] However, existing drying equipment for electrophoretic coating of aluminum profiles typically uses a fixed drying method. During the drying process, heat is concentrated in a fixed area, which can easily lead to excessively high local temperatures on the electrophoretic surface of the aluminum profile. This local overheating can cause a series of quality problems in the coating, such as discoloration, cracking, and peeling, which seriously affect the appearance and protective performance of the aluminum profile. In addition, due to uneven heat distribution, some areas are under-dried while others are over-dried, resulting in poor overall drying quality, reduced product qualification rate, and decreased drying quality and efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a drying device for electrophoretic coating of aluminum profiles. This drying device solves the problem that heat is concentrated in a fixed area during the drying process of a fixed dryer, which leads to excessively high local temperature on the electrophoretic surface of the aluminum profile or uneven drying, resulting in a series of quality problems in the electrophoretic coating of the aluminum profile.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drying device for electrophoretic coating of aluminum profiles includes a dryer, a frame fixedly installed on the surface of the dryer, and an electrical box fixedly installed inside the frame.

[0007] It also includes movable components for adjusting the angle of electrophoretic drying of aluminum profiles;

[0008] A movable component for improving the efficiency of electrophoretic drying of aluminum profiles;

[0009] The active components include: a drive motor, which is fixedly installed on the outer wall of the dryer; a rotating shaft is fixedly installed on the output shaft surface of the drive motor; the rotating shaft is rotatably connected to the inner wall of the dryer; a sliding rod is slidably connected to the surface of the rotating shaft; a reciprocating lead screw is fixedly installed inside the rotating shaft; an abutting shaft is threadedly connected to the surface of the reciprocating lead screw; and a fixing plate is fixedly installed on the surface of the abutting shaft.

[0010] Preferably, a fixing frame is fixedly installed on the inner wall of the dryer, the sliding rod is slidably connected to the inner wall of the fixing frame, and the fixing plate passes through the fixing frame.

[0011] Preferably, a connecting rod is fixedly installed on the surface of the fixed frame, a rotating rod is rotatably connected to the inner side of the connecting rod, a spiral spring is fixedly installed on the surface of the rotating rod, the spiral spring is fixedly installed on the inner side of the connecting rod, a connecting block is fixedly installed on the surface of the rotating rod, one end of an air pipe is fixedly installed on the top of the connecting block, and the other end of the air pipe is fixedly installed on the inner side of the dryer.

[0012] Preferably, the moving component includes: a movable shaft rotatably connected inside the connecting block, the movable shaft passing through the connecting block, a drying head fixedly mounted on the surface of the movable shaft, and the drying head hinged to the bottom of the connecting block.

[0013] Preferably, a connecting strip is fixedly installed on the outer side of the movable shaft. One end of the connecting strip is hinged to one end of a push rod, the other end of the push rod is hinged to one end of a sliding rod, the other end of the connecting strip is hinged to one end of a pull rod, and the other end of the pull rod is hinged to the other end of the sliding rod.

[0014] Preferably, the surface of the rotating shaft is provided with a reciprocating groove, and the surface of the fixing frame is provided with a groove.

[0015] Preferably, the cross-section of the fixing plate is U-shaped, and the cross-section of the connecting rod is L-shaped.

[0016] By employing the above technical solution, this utility model provides a drying device for electrophoretic coating of aluminum profiles. It possesses at least the following beneficial effects:

[0017] (1) By setting up the movable components, the present invention drives the motor to drive the rotation of the rotating shaft during use. When the rotating shaft rotates, it will drive the abutting shaft to move towards the surface of the connecting block through the fixed plate via the reciprocating screw and abut against the surface of the connecting block, causing the connecting block to swing and the bottom drying head to swing. When the abutting shaft releases its contact with the connecting block, the drying head will reset under the action of the spiral spring via the rotating rod, thereby achieving the effect of back-and-forth swinging. This can prevent local heat from being too concentrated during the drying process, and avoid the problem of over-drying of certain fixed parts of the aluminum material due to heat being concentrated for a long time, resulting in discoloration, cracking, peeling and other problems affecting the quality of electrophoretic coating due to overheating. This improves the quality and efficiency of drying.

[0018] (2) By setting the moving component, when the sliding rod slides, it will also drive the push rod hinged on its surface to abut against the surface of the connecting strip, and drive the rotation of the movable shaft through the connecting strip. When the movable shaft rotates, it will drive the drying head to swing. Since the reciprocating groove opened on the surface of the rotating shaft can achieve the effect of reciprocating sliding, the drying head swings back and forth at the bottom of the connecting block. This can prevent the airflow inside the dryer from being obstructed, forming a dead zone, and preventing the hot air from circulating effectively and the solvent vapor from being difficult to discharge, thereby improving the drying effect and enhancing the equipment's versatility.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] A drying device for electrophoretic coating of aluminum profiles, such as Figures 1-6 As shown, it includes a dryer 1, a frame 2 is fixedly installed on the surface of the dryer 1, and an electrical box 3 is fixedly installed inside the frame 2;

[0031] It also includes an active component 4 for adjusting the angle of the aluminum profile electrophoretic drying process;

[0032] Moving component 5 is used to improve the efficiency of electrophoretic drying of aluminum profiles;

[0033] First, the active component 4 includes: a drive motor 41, which is fixedly mounted on the outer wall of the dryer 1; a rotating shaft 42 is fixedly mounted on the output shaft surface of the drive motor 41; the rotating shaft 42 is rotatably connected to the inner wall of the dryer 1; a sliding rod 43 is slidably connected to the surface of the rotating shaft 42; a reciprocating screw 44 is fixedly mounted inside the rotating shaft 42; a contact shaft 45 is threadedly connected to the surface of the reciprocating screw 44; and a fixing plate 46 is fixedly mounted on the surface of the contact shaft 45. The rotation of the rotating shaft 42 simultaneously drives the rotation of the reciprocating screw 44. When the reciprocating screw 44 rotates, the contact shaft 45 moves away from the rotating shaft 42.

[0034] Secondly, a fixed frame 47 is fixedly installed on the inner wall of the dryer 1. A sliding rod 43 is slidably connected to the inner wall of the fixed frame 47. A fixed plate 46 passes through the fixed frame 47. A connecting rod 48 is fixedly installed on the surface of the fixed frame 47. A rotating rod 49 is rotatably connected to the inner side of the connecting rod 48. A spiral spring 412 is fixedly installed on the surface of the rotating rod 49. The spiral spring 412 is fixedly installed on the inner side of the connecting rod 48. A connecting block 410 is fixedly installed on the surface of the rotating rod 49. One end of an air pipe 411 is fixedly installed on the top of the connecting block 410. The other end of the air pipe 411 is fixedly installed inside the dryer 1. The hot airflow of the dryer 1 can enter the interior of the connecting block 410 through the air pipe 411 and be released through the drying head 52.

[0035] In this embodiment, the movable component 4 drives the motor 41 to rotate the rotating shaft 42 during use. When the rotating shaft 42 rotates, it drives the abutting shaft 45 to move towards the surface of the connecting block 410 via the reciprocating screw 44 and the fixing plate 46, and abuts against the surface of the connecting block 410, causing the connecting block 410 to swing and the drying head 52 at the bottom to swing. When the abutting shaft 45 releases its contact with the connecting block 410, the drying head 52 will reset under the action of the spiral spring 412 via the rotating rod 49, thereby achieving the effect of reciprocating back and forth swinging. This can prevent excessive local heat concentration during the drying process and avoid over-drying of certain fixed parts of the aluminum material due to prolonged heat concentration. This can prevent the surface coating from discoloring, cracking, peeling, and other problems that affect the quality of electrophoretic coating due to overheating, thus improving the quality and efficiency of drying.

[0036] Example 2

[0037] like Figure 7 As shown, the movable component 5 includes: a movable shaft 51, which is rotatably connected inside the connecting block 410 and passes through the connecting block 410. A drying head 52 is fixedly mounted on the surface of the movable shaft 51 and is hinged to the bottom of the connecting block 410.

[0038] Furthermore, a connecting strip 53 is fixedly installed on the outside of the movable shaft 51. One end of the connecting strip 53 is hinged to one end of the push rod 54, and the other end of the push rod 54 is hinged to one end of the sliding rod 43. The other end of the connecting strip 53 is hinged to one end of the pull rod 55, and the other end of the pull rod 55 is hinged to the other end of the sliding rod 43. The drying head 52 can swing at the bottom of the connecting block 410 by the mutual cooperation of the push rod 54 and the pull rod 55 against the connecting strip 53.

[0039] Finally, a reciprocating groove 420 is provided on the surface of the rotating shaft 42, which can drive the sliding rod 43 to slide back and forth on the surface of the rotating shaft 42. A groove 470 is provided on the surface of the fixed frame 47, which can allow the sliding rod 43 to slide inside the fixed frame 47. The cross-section of the fixed plate 46 is U-shaped, which can restrict the fixed plate 46 when it slides to a certain position. The cross-section of the connecting rod 48 is L-shaped, which can improve the connection effect between the connecting rod 48 and the rotating rod 49.

[0040] In this embodiment, by setting the moving component 5, when the sliding rod 43 slides, it will also drive the push rod 54 hinged to its surface to abut against the surface of the connecting bar 53, and drive the rotation of the movable shaft 51 through the connecting bar 53. When the movable shaft 51 rotates, it will drive the drying head 52 to swing. Since the reciprocating groove 420 opened on the surface of the rotating shaft 42 can achieve the effect of reciprocating sliding, the drying head 52 swings back and forth at the bottom of the connecting block 410. This can prevent the surrounding air from being poorly circulated inside the dryer 1, forming an airflow dead zone, and hot air from being unable to circulate effectively and solvent vapor from being difficult to discharge, thereby improving the drying effect and enhancing the versatility of the equipment.

[0041] In use, the drying device for electrophoretic coating of aluminum profiles of this utility model allows the aluminum profile to be placed inside the dryer 1 for drying. During drying, the drive motor 41 is activated to drive the rotation of the rotating shaft 42. When the rotating shaft 42 rotates, it drives the sliding rod 43 to slide back and forth on the surface of the rotating shaft 42 through the reciprocating groove 420 on its surface. When the rotating shaft 42 rotates, it also drives the reciprocating screw 44 to rotate. When the reciprocating screw 44 rotates, it drives the abutting shaft 45 to move towards the surface of the connecting block 410 through the fixing plate 46. When the abutting shaft 45 moves and abuts against the surface of the connecting block 410, it is ready to be used. When the connecting block 410 swings via the rotating rod 49, the drying head 52 at the bottom will swing as well. When the contact shaft 45 releases its contact with the connecting block 410, the drying head 52 will return to its original position via the rotating rod 49 under the action of the spiral spring 412, thus achieving a back-and-forth swinging effect. This can prevent excessive local heat concentration during the drying process and avoid over-drying of certain fixed parts of the aluminum material due to prolonged heat concentration. This can prevent problems such as discoloration, cracking, and peeling of the surface coating due to overheating, which affect the quality of electrophoretic coating and improve the quality and efficiency of drying.

[0042] When the sliding rod 43 slides under the action of the rotating shaft 42, it will also drive the push rod 54 hinged to its surface to abut against the surface of the connecting bar 53, and drive the rotation of the movable shaft 51 through the connecting bar 53. When the movable shaft 51 rotates, it will drive the drying head 52 to swing. Since the reciprocating groove 420 opened on the surface of the rotating shaft 42 can achieve the effect of reciprocating sliding, the sliding rod 43 will also achieve the effect of reciprocating sliding when it slides. When sliding, it pushes the push rod 54, and when resetting, it pulls the sliding rod 43 through the pull rod 55, so that the drying head 52 swings back and forth at the bottom of the connecting block 410. This can prevent the surrounding air from being poorly circulated inside the dryer 1, forming an airflow dead zone, and hot air from being unable to circulate effectively and solvent vapor from being difficult to discharge, thereby improving the drying effect and enhancing the versatility of the equipment.
