Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, and in particular to an electrostatic adsorption-enhanced powder coating uniform spraying device. Background Technology

[0002] Powder coating is a technology that involves spraying powder coating onto the surface of a workpiece using electrostatic spraying equipment and then curing it at high temperature to form a coating. During the spraying process, different spray heads need to be used depending on the type of material being coated.

[0003] When spraying, switching spray heads requires removing the original spray head using a quick-release connection and then installing the new spray head. This allows for adaptation to the shape and material of various materials when spraying different types of boards.

[0004] However, while quick-release spray head replacement is convenient, the need to sort and remove each head and put it back after use, along with the storage and installation of various different spray heads, leads to low spraying efficiency. Therefore, this application proposes an electrostatic adsorption enhanced powder coating uniform spraying device. Utility Model Content

[0005] The purpose of this invention is to address the problem that while quick-release spray head replacement is convenient in the background art, the need to select and remove different spray heads each time, and then put them back after use, leads to low spraying efficiency due to the storage and installation of multiple different spray heads. Therefore, this invention proposes an electrostatic adsorption-enhanced powder coating uniform spraying device.

[0006] The technical solution of this utility model: an electrostatic adsorption enhanced powder coating uniform spraying device, including a spraying pipe, a rotating frame fixedly connected to the bottom of the spraying pipe, two sets of rotating frames arranged symmetrically, a rotating shaft rotatably connected inside the rotating frame, a rotating plate fixedly connected to the opposite side of the rotating shaft, a turntable rotatably connected to the end of the rotating plate away from the rotating frame, the turntable abutting against one end of the spraying pipe, an installation groove opened inside the turntable, and a replacement head set inside the installation groove.

[0007] Optionally, the mounting slots are arranged in a circular array inside the turntable, and one of the replacement heads abuts against one side of the spray pipe, and the replacement head is connected to the spray pipe.

[0008] Optionally, the spray pipe has a positioning groove on the side near the turntable, a positioning spring is fixedly connected inside the positioning groove, and a positioning ball is fixedly connected to the end of the positioning spring away from the positioning groove, the positioning ball being fitted into one side of the turntable.

[0009] Optionally, a positioning pin is slidably connected inside the rotating frame, the positioning pin passing through the rotating frame and the rotating plate, and a positioning frame is fixedly connected to the outside of the spray pipe, the positioning frame being slidably connected to the outside of the turntable.

[0010] Optionally, the positioning frame is arranged in an "L" shape, and a connecting handle is fixedly connected to the outside of the spray tube.

[0011] Optionally, a connecting pipe is fixedly connected inside the connecting handle, and the connecting pipe is connected to the inside of the spraying pipe.

[0012] Optionally, a push groove is provided inside the turntable near the replacement head, a push spring is fixedly connected inside the push groove, and an installation component is provided at the end of the push spring away from the push groove.

[0013] Optionally, the mounting assembly includes a mounting block with a rounded corner at the end away from the push spring, and the end of the mounting block away from the push spring is fitted onto the outside of the replacement head.

[0014] Compared with the prior art, this application includes at least one of the following beneficial technical effects: the rotation of the rotating plate can control whether the turntable is in contact with the spray pipe, thereby facilitating the filling of different replacement heads into the turntable. When the replacement head needs to be switched, the turntable can be rotated so that the positioning spring pushes the positioning ball to position the turntable, thus achieving the effect of quick switching of replacement heads. This solves the problem that the quick-disassembly structure requires multiple disassemblies and reassemblies to replace the replacement head, resulting in slow replacement efficiency and affecting the spraying efficiency, thereby improving the switching speed of the replacement head and the spraying efficiency.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, the electrostatic adsorption enhanced powder coating uniform spraying device proposed in this utility model includes a spraying pipe 1. A rotating frame 8 is fixedly connected to the bottom of the spraying pipe 1. There are two sets of rotating frames 8 arranged symmetrically. A rotating shaft 9 is rotatably connected inside the rotating frame 8. A rotating plate 2 is fixedly connected to one side of the rotating shaft 9. The rotating plate 2 can be controlled to rotate between the rotating frames 8 by the rotating shaft 9. A turntable 3 is rotatably connected to the end of the rotating plate 2 away from the rotating frame 8. The turntable 3 abuts against one end of the spraying pipe 1. An installation groove 17 is opened inside the turntable 3. A replacement head 4 is set inside the installation groove 17. The rotation of the turntable 3 can control the replacement head 4 inside the installation groove 17 to communicate with the spraying pipe 1, thereby switching the spraying.

[0024] like Figures 1-3 As shown, there are multiple mounting slots 17 arranged in a circular array inside the turntable 3. Multiple replacement heads 4 are for different powder spraying amounts, which can be switched by rotating the turntable 3. One end of one replacement head 4 is attached to one side of the spray tube 1. The replacement head 4 is connected to the spray tube 1. A positioning slot 13 is opened on the side of the spray tube 1 near the turntable 3. A positioning spring 6 is fixedly connected inside the positioning slot 13. A positioning ball 5 is fixedly connected to the end of the positioning spring 6 away from the positioning slot 13. The positioning ball 5 does not prevent the turntable 3 from rotating. The positioning ball 5 is fitted into one side of the turntable 3 and can also position the turntable 3.

[0025] like Figures 2-3As shown, a positioning pin 10 is slidably connected inside the rotating frame 8. The positioning pin 10 passes through the rotating frame 8 and the rotating plate 2. The positioning pin 10 can fix the position of the rotating plate 2. A positioning frame 7 is fixedly connected to the outside of the spray tube 1. The positioning frame 7 is slidably connected to the outside of the turntable 3. The positioning frame 7 can provide auxiliary support for the turntable 3 and allow it to rotate. The positioning frame 7 is L-shaped and can wrap around the turntable 3. A connecting handle 11 is fixedly connected to the outside of the spray tube 1. A connecting pipe 12 is fixedly connected inside the connecting handle 11. The connecting pipe 12 can transmit the powder material. The connecting pipe 12 is connected to the inside of the spray tube 1 and can transmit the powder material into the inside of the spray tube 1.

[0026] In this embodiment, when in use, the positioning pin 10 is removed from the inside of the rotating frame 8 and the rotating plate 2, and then the rotating plate 2 is rotated along the rotating frame 8 by the rotating shaft 9. In this way, the turntable 3 will detach from one side of the spray tube 1. At this time, the replacement head 4 can be installed inside the multiple mounting slots 17. Then, the rotating plate 2 is rotated along the rotating frame 8, and the positioning pin 10 is inserted into the inside of the rotating frame 8 and the rotating plate 2 to fix the turntable 3.

[0027] By rotating the turntable 3, different replacement heads 4 can be connected to the spray tube 1, thereby replacing different replacement heads 4. When the turntable 3 rotates, the positioning frame 7 can protect the turntable 3 to prevent the powder sprayed from inside the spray tube 1 from pushing the turntable 3 away from one end of the spray tube 1.

[0028] When the turntable 3 is rotated, the positioning spring 6 pushes the positioning ball 5 to engage with the replacement head 4 inside the positioning groove 13, thereby positioning the turntable 3. In this way, the operator can hold the connecting handle 11 and let the powder be conducted from the connecting pipe 12 to the inside of the spray pipe 1, and then use different replacement heads 4 to spray the powder.

[0029] It should be noted that the rotating plate 2 of this device can control whether the turntable 3 is in contact with the spray pipe 1, thereby facilitating the filling of different replacement heads 4 into the turntable 3. When the replacement head 4 needs to be switched, the turntable 3 can be rotated so that the positioning spring 6 pushes the positioning ball 5 to position the turntable 3, thus achieving the effect of quickly switching the replacement head 4. This solves the problem that the quick-release structure requires multiple disassembly and assembly when replacing the replacement head 4, resulting in slow replacement efficiency and affecting the spraying efficiency, and improves the switching speed and spraying efficiency of the replacement head 4.

[0030] Example 2

[0031] like Figure 2 and Figure 3As shown, based on Embodiment 1, a push groove 15 is provided inside the turntable 3 near the replacement head 4. A push spring 14 is fixedly connected inside the push groove 15. The push spring 14 can extend and retract inside the push groove 15. An installation component is provided at the end of the push spring 14 away from the push groove 15. The installation component includes a mounting block 16. The end of the mounting block 16 away from the push spring 14 is rounded. The rounded corner of the push spring 14 can be perfectly embedded inside the replacement head 4, thereby allowing the push spring 14 to position the replacement head 4. The end of the mounting block 16 away from the push spring 14 is fitted onto the outside of the replacement head 4.

[0032] In this embodiment, when the replacement head 4 is installed into the mounting groove 17, the push spring 14 can push the mounting block 16 into the replacement head 4 inside the push groove 15, so that the mounting block 16 positions the replacement head 4. When the replacement head 4 needs to be removed, the rounded corners of the mounting block 16 will not obstruct the filling of the replacement head 4.

[0033] It should also be noted that this device uses a push spring 14 to push the mounting block 16 inside the push groove 15, which allows the mounting block 16 to position the replacement head 4. This solves the problem that the replacement head 4 will become loose from the mounting groove 17 if it is only embedded inside the mounting groove 17, and improves the positioning effect of the replacement head 4 when it is installed into the mounting groove 17.

[0034] 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.
