Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, and in particular to an automatic lifting rotating frame for powder coating workpieces. Background Technology

[0002] Powder coating is a process in which powder coating equipment is used to spray powder coating onto the surface of a workpiece. Under the action of static electricity, the powder will be evenly adsorbed onto the surface of the workpiece to form a powdery coating. During powder coating, the workpiece to be coated needs to be fixed on a rotating frame.

[0003] After the workpiece is hung on the rotating frame, powdered raw materials are sprayed onto the surface of the workpiece through the spray head. After one side of the workpiece is sprayed, the rotating frame is rotated by the motor, thereby flipping the workpiece. This allows for spraying of the workpiece without dead angles.

[0004] However, when hanging the workpiece on the spraying rack, if the workpiece is heavy, two people are needed to operate it, which makes hanging the workpiece inconvenient. Therefore, this application proposes an automatic lifting rotary rack for powder coating workpieces. Utility Model Content

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figures 1-3 As shown, this utility model proposes an automatic lifting powder coating workpiece rotating frame, including a lifting rod 1. The lifting rod 1 is arranged in an inverted "T" shape. The "T" shape of the lifting rod 1 can stably suspend the workpiece. Wear-resistant rings 18 are fixedly connected to the outside of the lifting rod 1. There are two wear-resistant rings 18 arranged symmetrically. The wear-resistant rings 18 facilitate the suspension of the workpiece. A spray box 15 is provided outside the lifting rod 1. A collection platform 17 is fixedly connected to the inside of the spray box 15 near the bottom. Powder falling on the surface of the collection platform 17 can be collected. An opening is provided on one side of the spray box 15 near the collection platform 17. The lifting rod 1 has an operating port 16, which facilitates the use of a powder spray gun to spray the workpiece. A protective box 10 is provided on the outside of the lifting rod 1. A stretching groove 11 is provided on the inner side of the protective box 10 near the lifting rod 1. The stretching groove 11 is inclined and there are two stretching grooves 11 symmetrically provided on the inner side of the protective box 10. A sliding rod 12 is slidably connected inside the stretching groove 11. The sliding rod 12 can slide along the stretching groove 11 to descend. The sliding rod 12 is fixedly connected to the outside of the lifting rod 1. The lifting rod 1 can be driven to descend by sliding the sliding rod 12 inside the stretching groove 11. A drive assembly is provided on the top of the lifting rod 1.

[0027] like Figure 3 , Figure 5 and Figure 7As shown, the drive assembly includes a motor 9, and a drive rod 8 is fixedly connected to the output end of the motor 9. The motor 9 can drive the drive rod 8 to rotate. The drive rod 8 is hexagonal and is located inside the lifting rod 1 near the top. The top of the lifting rod 1 has a fitting groove 7. The drive rod 8 fits into the groove 7 and can drive the lifting rod 1 to rotate. The outer part of the fitting groove 7 near the drive rod 8 is rounded. The rounded corner structure of the fitting groove 7 facilitates the insertion of the drive rod 8. The rounded corner structure of the drive rod 8 near the fitting groove 7 can prevent wear caused by the rounded corner structure of the fitting groove 7.

[0028] like Figures 3-5 As shown, a protective shell 5 is fixedly connected to the outside of the motor 9, which can protect the motor 9. A spring 4 is fixedly connected to the side of the protective shell 5 away from the motor 9. The spring 4 can cooperate with the lifting rod 1 to descend and reset. A rotating component is provided at the end of the spring 4 away from the protective shell 5. The rotating component includes a rotating ring 3, which is fixedly connected to the end of the spring 4 away from the protective shell 5. A positioning ring 2 is rotatably connected to the outside of the rotating ring 3. The rotating ring 3 rotates by being fitted inside the positioning ring 2. The positioning ring 2 is fixedly connected to the outside of the lifting rod 1. When the lifting rod 1 descends, it pulls the positioning ring 2 to move. The rotating ring 3 rotates inside the positioning ring 2 and will not damage the spring 4. A positioning sleeve 6 is fixedly connected to the side of the protective shell 5 near the spring 4. The positioning sleeve 6 is set inside the spring 4 and can restrict the lifting rod 1 to prevent the lifting rod 1 from being unable to align with the drive rod 8. The positioning sleeve 6 is slidably connected to the outside of the lifting rod 1.

[0029] In this embodiment, during use, the lifting rod 1 is pulled, causing the lifting rod 1 to drive the slide rod 12 to slide along the inside of the stretching groove 11, so that the lifting rod 1 will descend. Then, the workpiece is threaded through the wire and hung on the outside of the wear-resistant ring 18. At this time, the operator applies an upward force under the workpiece with his hand, so that the slide rod 12 slides back to its original position along the inside of the stretching groove 11.

[0030] When the slide bar 12 is reset, the spring 4 assists in pulling upward, thereby resetting the workpiece. At this time, the powder spray gun can be placed into the spray box 15 along the operating port 16 to spray the workpiece with powder. The protective box 10 can protect the lifting rod 1 and other parts inside the protective box 10.

[0031] After one side of the workpiece is coated, the motor 9 drives the drive rod 8 to rotate inside the protective shell 5. The drive rod 8 then drives the lifting rod 1 to rotate inside the fitting groove 7. When the lifting rod 1 rotates, the rotating ring 3 rotates inside the positioning ring 2, so it will not cause deformation to the spring 4. When the spring 4 is stretched, the rotating ring 3 is embedded inside the positioning ring 2, which can also be used to stretch the spring 4 in conjunction with the descent of the lifting rod 1.

[0032] After the spraying is completed, apply a pulling force to the bottom of the workpiece. When you feel the lifting rod 1 loosen, you can pull it towards the operating port 16. This will allow you to remove the workpiece and wire suspended at the wear ring 18, and then replace the workpiece for spraying again.

[0033] It should be noted that this device uses a sliding rod 12 to slide along the tension groove 11 to control the lifting rod 1 to move up and down. The rotating ring 3 fixed by the spring 4 rotates and engages inside the positioning ring 2, which allows the lifting rod 1 to rotate independently and also allows the spring 4 to extend and retract in coordination with the lifting rod 1. This solves the problem that two operators were required to install heavy workpieces in the past, which made it difficult to install and disassemble the workpieces. It also improves the convenience of suspending different workpieces.

[0034] Example 2

[0035] like Figure 3 and Figure 5 As shown, based on Embodiment 1, the protective box 10 is fixedly connected to the inside of the spray box 15 near the top. The protective box 10 can protect the lifting rod 1. The top of the protective box 10 is provided with a sliding groove 13. There are two sets of sliding grooves 13 arranged symmetrically. A slider 14 is slidably connected inside the sliding groove 13. The slider 14 can restrict the movement direction of the protective shell 5 by sliding along the inside of the sliding groove 13. The slider 14 is fixedly connected to the side of the protective shell 5 away from the motor 9.

[0036] In this embodiment, when the lifting rod 1 slides back and forth, the connection of the spring 4 will cause the protective shell 5 to slide. When the protective shell 5 slides, it relies on the slider 14 to slide inside the groove 13 to ensure that the stress on the connection of the spring 4 is not too great, thus ensuring the stability of the connection of the spring 4.

[0037] It should also be noted that the device uses a slider 14 that slides inside the groove 13, which allows the protective shell 5 and the motor 9 to move synchronously with the lifting rod 1. This ensures that the connection of the spring 4 will not be subjected to excessive stress during movement and stretching, thereby improving the stability of the sliding of the protective shell 5 and the motor 9 and reducing the stress at the connection when the spring 4 extends or retracts.

[0038] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
