The fixing ring 430 is located inside the U-shaped frame 420, between the support arms 422 on both sides, and each fixing ring 430 is composed of two semicircular fixing frames, which are fixedly connected to the support arms 422 on both sides. The axial direction of the fixing ring 430 is in the same direction as the opening of the U-shaped frame 420. Although in this embodiment, the number of fixing rings 430 is two, the utility model does not limit the number of fixing rings 430. The powder coating barrel includes a coaxial inner barrel 100 and an outer barrel 200, and a roller is arranged inside the fixing ring 430, and the outer barrel 200 and the fixing ring 430 are connected in a rolling manner through the roller. In addition, a barrel cover is also arranged at the front opening of the powder coating barrel. When the sensitive claw is coated with powder, the sensitive claw is placed in the inner barrel 100, the carbon powder is placed in the outer barrel 200, and then the rotation of the coating barrel is started by the driving component 300, so that the surface of the sensitive claw is evenly coated with carbon powder. This device has a reasonable structural design and is easy to operate.

The operator can quickly and accurately control the position of the second limit assembly 470, thereby realizing the switching between the powder coating and powder removal processes. In addition, the knob plunger structure has good sealing performance, which can effectively prevent dust or other impurities from entering the interior of the device, and ensure the stability and reliability of the device. Therefore, by adopting the knob plunger as the fourth connecting member 471, this embodiment realizes the rapid operation of the second limit assembly 470, improves the operability and use efficiency of the device, and ensures the stability and safety of the device during use.

[0076] In order to further protect the powder coating bucket from rotating within a safe range, protect the structure of the powder coating device, extend the service life and reduce the failure rate, the bracket 400 also includes a support member 440, which is arranged on the base 450 included in the bracket 400, and a buffer member with an inclined surface is arranged at the top of the support member 440, and the inclination angle of the inclined surface of the buffer member matches the angle setting of the powder coating bucket. In this embodiment, the setting of the support member 440 further strengthens the protection and stability of the powder coating device. A buffer member with an inclined surface is arranged at the top of the support member 440, and the inclination angle of the inclined surface of the buffer member is precisely designed to match the setting of the maximum inclination angle of the powder coating bucket, ensuring that the buffer member can provide protection for the powder coating bucket during the operation of the powder coating device, and provide stable support and buffering. Such a design effectively extends the service life of the powder coating device and improves the operational stability and safety of the device. By arranging the support member 440 and the buffer member in the bracket 400, this embodiment further protects the rotation of the powder coating bucket within a safe range, reduces the structural loss and failure rate of the device, and thus improves the overall reliability and service life of the device.

[0077] In order to further adjust the amount of powder coating and the uniformity of powder coating, and improve the operating efficiency and powder coating quality of the device, the circumference of the inner barrel 100 is provided with mesh holes, and the inner side of the circumference of the inner barrel 100 is provided with blades 130. In this embodiment, the inner barrel 100 adopts the design of a mesh barrel 110, and the diameter of a single mesh of the mesh barrel is 2.5 mm, and its specification is 120 mesh holes per circle, and the mesh barrel is provided with 23 circles. Such a design allows the powder to pass through the surface of the inner barrel 100 evenly, ensuring that it is evenly covered on the sensitive claws. The design of the mesh barrel 110 can help control the amount of powder coating and prevent too much powder from being put in at one time, thereby improving the uniformity and quality of the powder coating. In addition, the inner side of the circumference of the inner barrel 100 is provided with blades 130, which can drive the sensitive claws and carbon powder to rise and then fall when the inner barrel 100 rotates, ensuring the uniform distribution of the powder. Through the design of the blades 130, the uniformity of the powder coating can be effectively improved, and the powder can be prevented from gathering inside the inner barrel 100, thereby ensuring the quality and stability of the powder coating. In summary, the inner barrel 100 designed with the mesh barrel 110 and the blades 130 can effectively adjust the amount of powder coating and improve the uniformity of powder coating, thereby improving the operating efficiency and powder coating quality of the device. This design can better meet the user's requirements for powder coating effects and enhance the practicality and competitive advantage of the device.

[0078] There are two main scenarios when using the sensitive claw powder coating device to coat sensitive claws:

[0079] Powder coating scene: In the powder coating scene, the operator first adjusts the U-shaped frame 420 of the powder coating device so that the powder coating barrel is 35 degrees upward, inserts the knob plunger as the third connecting member 461 in the first selection limit assembly, and fixes the powder coating barrel. Then, the operator removes the cover plate, takes out the inner barrel 100 along the guide shaft 322, and pours 25g of carbon powder into the bottom of the outer barrel 200. Next, the operator puts the inner barrel into the outer barrel 200, puts 5000 sensitive claws in the inner barrel, and then pours 5g of carbon powder on the sensitive claws. Then, the operator covers the cover plate and rotates the handle to fix the cover plate. At this angle, the sensitive claw will fall to the bottom of the inner barrel to prevent it from falling outside. Next, the operator unplugs the knob plunger as the third connecting member 461 in the first selection limit assembly, adjusts the angle of the drum to 10 degrees upward, and then inserts the knob plunger of the third connecting member 461 to fix the angle of the drum. Next, the operator plugs in the knob plunger as the second connecting member 331 in the second transmission structure 330, so that the outer barrel 200 and the transmission shaft 311 are connected together, so that the inner barrel 100 and the outer barrel 200 can move synchronously. Then, the operator unplugs the knob plunger as the fourth connecting member 471 in the second limiting assembly 470 fixed to the outer side of the outer barrel 200 on the side of the powder coating device, so that the block on the outer barrel 200 is disconnected from the side support arm 422 of the U-shaped frame 420. Finally, the operator presses the start button, the powder coating device enters the automatic state, the drive assembly 300 starts, and the powder coating barrel starts to rotate to perform the powder coating operation. The inner barrel 100 and the outer barrel 200 both rotate, and the carbon powder in the outer barrel 200 is brought to a high place as the outer barrel connecting rod 210 inside the outer barrel 200 rotates and falls onto the sensitive claws in the inner barrel 100. The carbon powder and the sensitive claws in the inner barrel 100 are brought to a high place and fall down through the blades 130. During this process, the carbon powder is continuously wrapped around the sensitive claws.

[0080] After the powder coating operation is completed, the powder coating device reliably completes the powder coating process, ensuring the uniformity and stability of the powder coating. The program setting can be selected, and the powder coating device automatically stops rotating after rotating for the powder coating time. The use of automatic powder coating can improve operating efficiency, reduce manual intervention, and reduce labor intensity. In addition, the powder coating device can also set the powder coating time and control the time according to demand, thereby further improving the flexibility of operation and the quality of powder coating. Optionally, the powder coating time can be set to 10 to 20 minutes as needed, preferably 15 minutes. However, the utility model is not limited to this. Optionally, a buzzer can be configured to buzz and remind after the powder coating is completed.

[0081] Powder removal scenario: In the powder removal scenario, the operator first unplugs the knob plunger as the third connecting member 461 in the first selection limit assembly, and adjusts the angle of the roller to 35 degrees upward to disengage the inner barrel 100 and the outer barrel 200. Then, the operator disengages the knob plunger as the second connecting member 331 in the second transmission structure 330 to disengage the inner barrel 100 and the outer barrel 200. Next, the operator plugs in the knob plunger as the fourth connecting member 471 in the second limit assembly 470 on the side of the powder coating device, connects the outer barrel 200 to the side support arm 422 of the U-shaped frame 420, fixes the outer barrel 200, and prevents the friction between the inner barrel 100 and the outer barrel 200 from driving the outer barrel 200 to rotate. At this time, the powder coating device enters the automatic state, the operator presses the start button, and the powder coating device starts to rotate automatically to perform the powder removal operation. During the powder removal process, the inner barrel 100 starts to rotate, while the outer barrel 200 is fixed. Due to the vibration caused by the rotation of the inner barrel 100, the carbon powder on the outer barrel 200 will gradually fall down. At the same time, the carbon powder and sensitive claws in the inner barrel 100 will be continuously brought to a high place and fall down as the inner barrel 100 rotates. Excess carbon powder and carbon powder that is not wrapped on the surface of the sensitive claws will fall to the inside of the outer barrel 200 through the mesh of the inner barrel 100. The operator can also set the powder removal time as needed to ensure the thoroughness and efficiency of the powder removal. The flexible setting of the powder removal time further improves the convenience of operation and the applicability of the device. After the powder removal operation, the powder coating device effectively removes excess carbon powder from the sensitive claws, ensuring the powder coating quality and stability of the sensitive claws. The use of automatic powder removal makes the operation easier, improves work efficiency, reduces the need for manual intervention, and further reduces operating costs and risks. Optionally, the powder removal time can be set to 15 to 25 minutes as needed, preferably 20 minutes. Afterwards, the staff opens the cover, takes out the powder-coated sensitive claws, puts the powder-coated sensitive claws into a container, and waits to enter the subsequent process.

[0082] Figures 1 to 6In the embodiments, the axial direction of the center of the fixing ring 430 and the opening of the U-shaped frame 420 are used as examples for explanation. In other embodiments, the setting mode of the fixing ring 430 can be changed to adapt to different application scenarios and technical requirements. For example, the fixing ring 430 can be arranged on the U-shaped frame 420, rather than being located inside it. This setting mode can further improve the stability and reliability of the device, while reducing the overall size of the device in the left and right directions, making it more compact. In addition, the shape and number of the fixing ring 430 can also be adjusted according to specific needs to meet the use requirements in different situations. In addition, the connection mode of the fixing ring 430 can also adopt other forms, for example, adopting threaded connection and other methods to ensure that the connection between the fixing ring 430 and the bracket 400 is firm and reliable, and it is not easy to loosen or fall off. By flexibly adjusting the setting mode and connection mode of the fixing ring 430, the powder coating device can be made more suitable for different application scenarios and working environments, thereby improving its versatility and practicality. The use of fixed rings 430 with different settings and connection methods can effectively improve the stability and reliability of the powder coating device, reduce the failure rate of the device during operation, extend the service life of the device, and thus reduce maintenance costs and repair risks. At the same time, the optimized design of the fixed ring 430 can also improve the operating efficiency and powder coating quality of the device, bringing users a more convenient and efficient use experience.

[0083] Figures 1 to 6 In the embodiments, the driving assembly 300 is fixedly arranged at the bottom center of the U-shaped frame 420 as an example for explanation. In other embodiments, the arrangement of the driving assembly 300 can be adjusted and changed according to specific needs and design requirements. For example, the driving assembly 300 can be installed at other positions of the U-shaped frame 420, or at an appropriate position of the powder coating bucket. Such an arrangement can be flexibly designed according to the overall structure and use requirements of the device to improve the stability, reliability and operability of the device.

[0084] In addition, the form and type of the drive assembly 300 can also be selected according to specific circumstances. For example, an electric drive assembly, a pneumatic drive assembly, or a manually operated drive assembly can be selected to meet different power transmission requirements and working scenarios. In different embodiments, the structure and performance of the drive assembly 300 can also be optimized and improved to improve the working efficiency of the device, save energy, and reduce operating costs.

[0085] By flexibly setting the position of the drive assembly 300 and selecting a suitable drive mode, the powder coating device can be more adaptable to different working environments and operating requirements, thereby improving the flexibility and diversity of the device. At the same time, the optimized design of the drive assembly 300 can also improve the working efficiency and stability of the device, reduce the failure rate and maintenance cost of the equipment during operation, and thus reduce the user's use cost and risk.
