Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal surface treatment, in particular to a sheet metal plastic spraying device. Background Art

[0002] The spraying process is often used in the surface treatment of sheet metal parts to improve the appearance and corrosion resistance of sheet metal parts, thereby extending the service life of sheet metal parts. The device currently used for spraying sheet metal is referred to as the "sheet metal spraying bracket" disclosed in the publication number CN214515441U. Generally, a hook is used to hang the sheet metal part on the spraying bracket. However, this method has the problem that the part of the sheet metal part that contacts the hook cannot be sprayed, which requires additional spraying. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a sheet metal plastic spraying device which can avoid the hook from hindering the plastic spraying.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a sheet metal spraying device, comprising a spraying chamber, a hanger and a suspension rod; a motor is arranged on the spraying chamber, and a cam drivingly connected to the output shaft of the motor is arranged inside the spraying chamber;

[0005] The bracket is provided with a movable limit plate, the movable limit plate is provided with a long hole opened in the vertical direction, the end of the suspension rod passes through the long hole and abuts against the wheel surface of the cam, and a plurality of hooks are swingably provided on the rod body of the suspension rod.

[0006] Furthermore, the cam includes a turntable and a protrusion; the turntable is drivingly connected to the output shaft of the motor, and the protrusion is fixed on the turntable surface by bolts and nuts.

[0007] Furthermore, at least two protrusions are arranged on the surface of the turntable.

[0008] Furthermore, the suspension rod is a suspension rail, a plurality of suspension wheels are slidably provided on the suspension rail, and ropes connected to hooks are tied to the suspension wheels.

[0009] Furthermore, the above-mentioned sheet metal spraying device also includes a guide slide groove, which at least extends into the interior of the spraying room, and the bottom of the hanger is slidably arranged in the guide slide groove.

[0010] Furthermore, the body of the motor is arranged on the outer wall of the spraying room.

[0011] The beneficial effect of the utility model is that a motor is added to the spraying chamber to drive the cam to rotate, and at the same time, the end of the suspension rod passes through the long hole of the movable limit plate and abuts against the wheel surface of the cam. During the spraying process, the motor can drive the suspension rod to move appropriately on the hanger, so that the sheet metal part can swing on the hook, thereby constantly changing the contact position between the hook and the sheet metal part, and then the powder can be fully sprayed on the surface of the sheet metal part.

[0020] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0021] Please refer to Figure 1 and Figure 2 As shown, the utility model is a sheet metal spraying device, comprising a spraying chamber 1, a hanger 2 and a suspension rod 3; the spraying chamber 1 is provided with a motor 11, and the spraying chamber 1 is provided with a cam 12 drivingly connected to the output shaft of the motor 11;

[0022] The bracket 2 is provided with a movable limit plate 21, and the movable limit plate 21 is provided with a long hole 211 opened in the vertical direction. The end of the suspension rod 3 passes through the long hole 211 and abuts against the wheel surface of the cam 12. A plurality of hooks 31 are swingably provided on the rod body of the suspension rod 3.

[0023] Working principle: A motor 11 is added to the spray chamber 1 to drive the cam 12 to rotate, and at the same time, the end of the suspension rod 3 passes through the long hole 211 of the movable limit plate 21 and abuts against the wheel surface of the cam 12. During the spraying process, the motor 11 can drive the suspension rod 3 to move appropriately on the hanger 2, so that the sheet metal can swing on the hook 31, thereby constantly changing the contact position between the hook 31 and the sheet metal, so that the powder can be fully sprayed on the surface of the sheet metal.

[0024] Please refer to Figure 3 As shown, further, the cam 12 includes a rotating disk 121 and a protrusion 122; the rotating disk 121 is drivingly connected to the output shaft of the motor 11, and the protrusion 122 is fixed on the disk surface of the rotating disk 121 by bolts and nuts.

[0025] From the above description, it can be seen that since the protrusion 122 is fixed on the surface of the turntable 121 by bolts and nuts, the amount by which the protrusion 122 protrudes from the edge of the turntable 121 can be adjusted according to actual needs to adjust the movement range of the suspension rod 3.

[0026] Please refer to Figure 3 As shown, further, at least two protrusions 122 are arranged on the disk surface of the turntable 121 .

[0027] It can be seen from the above description that by adding a plurality of protrusions 122 , the movement frequency of the suspension rod 3 can be adjusted according to actual needs.

[0028] Furthermore, the suspension rod 3 is a suspension rail, on which a plurality of suspension wheels are slidably provided, and on the suspension wheels are ropes connected to the hooks 31 .

[0029] It can be seen from the above description that by moving the lifting wheel on the lifting rod 3, the distance between adjacent hooks 31 can be adjusted, thereby adapting to the lifting of sheet metal parts of various sizes.

[0030] Please refer to Figure 1 and Figure 2 As shown, further, the above-mentioned sheet metal spraying device also includes a guide slide groove 4, which at least extends into the interior of the spraying room 1, and the bottom of the hanger 2 is slidably arranged in the guide slide groove 4.

[0031] As can be seen from the above description, the guide chute 4 can enable the hanger 2 to enter and exit the spraying room 1, and ensure that the hanger 2 can make the suspension rod 3 contact the wheel surface of the cam 12 after entering the spraying room 1. At the same time, since high-temperature curing is required after spraying, the guide chute 4 can be extended into the curing furnace of the workshop, so that the hanger 2 can directly carry the sprayed sheet metal into the curing furnace.

[0032] Please refer to Figure 1As shown, further, the body of the motor 11 is arranged on the outer wall of the spraying room 1.

[0033] It can be seen from the above description that placing the body of the motor 11 on the outer wall of the spraying room 1 can prevent the sprayed powder in the spraying room 1 from adhering to the motor 11 and affecting the service life of the motor 11.

The cam 12 includes a rotating disk 121 and a convex block 122; the rotating disk 121 is connected to the output shaft of the motor 11, and the three convex blocks 122 are fixed on the disk surface of the rotating disk 121 by bolts and nuts.

[0036] Working principle: A motor 11 is added to the spraying room 1 to drive the cam 12 to rotate, and at the same time, the end of the suspension rod 3 passes through the long hole 211 of the movable limit plate 21 and abuts against the wheel surface of the cam 12. During the spraying process, the motor 11 can drive the suspension rod 3 to move appropriately on the hanger 2, so that the sheet metal can swing on the hook 31, thereby constantly changing the contact position between the hook 31 and the sheet metal, and then the powder can be fully sprayed on the surface of the sheet metal. The body of the motor 11 is set on the outer wall of the spraying room 1.
