Abstract
Description
Technical Field
[0001] This utility model relates to the field of bushing technology, and in particular to a spraying equipment for a slotted bushing coating. Background Technology
[0002] Slotted bushings play an important role in aerospace and other fields, and have strict requirements for coating. As a disposable fastener, they not only require complete coating coverage, but also require rapid and efficient coating to meet the needs of large-scale use. In addition, since slotted bushings have folded and overlapping areas, and only the inner wall needs to be coated, coating after molding will result in incomplete coating at the slots, which will affect the use of the slotted bushing. Therefore, there is a need for a spraying equipment that can coat the raw material on one side before molding and can complete the process quickly.
[0003] Currently, the main method for coating the raw material of slotted bushings is to manually unroll the rolled material, clean it, and then use a handheld electrostatic spray gun to spray the inner wall of the slotted bushing. This process not only requires a large number of operators, but manual spraying is also prone to uneven coating, resulting in unqualified coatings and waste of paint, and the spraying efficiency is not high.

[0027] Please refer to Figures 1-3 A slit bushing coating spraying equipment includes a spraying bracket 1, on which a raw material installation mechanism, a raw material flattening and conveying mechanism, a cleaning mechanism, a drying and spraying mechanism, and a material rolling mechanism are sequentially arranged along the material conveying direction.

A plurality of roller brushes 5 are rotatably arranged between the first conveyor baffle 3 and the second conveyor baffle 4. The roller brushes 5 are located at the entrance of the first conveyor belt 2.
[0029] A drying hood 9, an electrostatic spray gun 7, and a heating box 8 are sequentially arranged on the first conveyor baffle 3 and the second conveyor baffle 4 along the conveying direction of the first conveyor belt 2. The drying hood 9 is connected to an external dryer. A vacuum cleaner 12 is arranged above the electrostatic spray gun 7. The vacuum cleaner 12 is connected to the storage tank 13 through a conveying pipe.

A second drive motor 15 is also provided on the first conveyor baffle 3. The second drive motor 15 is used to drive the first conveyor belt 2 to rotate.
[0031] In this embodiment, before spraying, the roller brush 5 and the drying hood 9 can dry the moisture on the raw material of the slotted bushing 10. Then, when the raw material of the slotted bushing 10 moves to the electrostatic spray gun 7, the paint can be sprayed onto the surface of the raw material of the slotted bushing 10 through the electrostatic spray gun 7. The above operation can improve the spraying efficiency. The electrostatic spray gun 7 is connected to an external paint storage tank through an infusion pipe.
[0032] A vacuum cleaner 12 is installed above the electrostatic spray gun 7. The vacuum cleaner 12 is connected to the storage tank 13 through the delivery pipe. Uncoated paint can be collected in the storage tank 13 by the suction generated by the vacuum cleaner 12, reducing evaporation and waste.
[0033] The raw material installation mechanism includes an installation groove 16, which is fixed on the spraying bracket 1. A fixed shaft 17 is rotatably installed inside the installation groove 16. A roller shaft 18 is provided at the outlet of the installation groove 16.
[0034] The raw material flattening and conveying mechanism includes a second conveyor belt body 19, which is rotatably mounted on the spraying bracket 1. A third conveying baffle 20 and a fourth conveying baffle 21 are respectively provided on both sides of the second conveyor belt body 19. A first roller group 22 and a second roller group 23 are rotatably arranged between the third conveying baffle 20 and the fourth conveying baffle 21. The first roller group 22 is located at the entrance of the second conveyor belt, and the second roller group 23 is located at the exit of the second conveyor belt.
[0035] A first drive motor 24 is provided on the third conveyor baffle 20 at a position opposite to the first roller group 22, a second drive motor 25 is provided on the third conveyor baffle 20 at a position opposite to the second roller group 23, and a third drive motor 26 is provided on the third conveyor baffle. The third drive motor 26 is used to drive the second conveyor belt 19 to rotate.
[0036] The cleaning mechanism includes an ultrasonic cleaning tank 6, above which a mechanical gripper 27 slides. The mechanical gripper 27 is used to hold and transfer the slit bushing 10 material. In this example, the mechanical gripper 27 can move the slit bushing 10 material to the ultrasonic cleaning tank 6 for cleaning, thereby removing surface impurities and improving the coating effect. The mechanical gripper 27 can be transferred by means of an external translation mechanism. Both the mechanical gripper 27 and the external translation mechanism are existing technologies, such as lead screw transmission mechanisms.
[0037] The material rolling mechanism includes a storage groove 28, which is fixed on the spraying bracket 1. A take-up shaft 29 is rotatably arranged inside the storage groove 28, and a clamping slot 30 is provided on the take-up shaft 29. A take-up motor 11 is horizontally arranged on one side of the storage groove 28, and the rotor of the take-up motor 11 is connected to the take-up shaft 29.
[0038] Working principle: The raw material is clamped on the fixed shaft 17 in the mounting groove 16 and passes under the roller shaft 18 to transition to the second transmission belt. The position of the roller shaft 18 can be adjusted according to the specifications of the raw material. The first drive motor 24, the second drive motor 25 and the third drive motor 26 are started. Under the action of the second conveyor belt 19, the raw material moves forward through the first roller group 22 to realize the unwinding operation.
[0039] Subsequently, under the action of the second conveyor belt 19, the unwound bushing 10 moves to the lower part of the second roller group 23. The rotation of the first roller group 22 causes one end of the bushing 10 to be sent to the lower part of the mechanical claw 27. The mechanical claw 27 clamps and holds the bushing 10. Then, under the action of the external translation mechanism, the mechanical claw 27 sends the bushing 10 into the ultrasonic cleaning tank 6. The cleaning temperature and working time of the ultrasonic cleaning tank 6 are controlled. After cleaning, the mechanical claw 27 sends one end of the cleaned bushing into the space between the roller brush 5 and the first conveyor belt 2.
[0040] When the first drive motor 14 and the second drive motor 15 are started, the roller brush 5 can remove the moisture on the surface of the bushing 10 by rotating. Under the action of the first conveyor belt 2, the bushing 10 is transported into the interior of the dryer, and under the action of the dryer, the moisture on its surface is completely dried.
[0041] The bushing 10 is then conveyed to the electrostatic spray gun 7. The paint in the paint storage tank is delivered to the electrostatic spray gun 7 through the infusion tube to spray the surface of the bushing 10. The uncoated and diffused paint is collected in the storage tank 13 by the suction generated by the vacuum cleaner 12. After spraying, the bushing 10 enters the heating box 8 for coating curing.
[0042] When one end of the bushing 10 moves into the clamping slot 30 on the take-up shaft 29, it is clamped and locked by the clamping slot. The take-up motor 11 controls the take-up shaft 29 to rotate clockwise so that the coating surface is inside, completing the roll. The mechanical claw 27 is reset, and then new raw materials are installed, and the above process is repeated.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
