Description

Technical Field

[0001] This utility model relates to the field of powder coating technology; more specifically, it relates to a powder coating equipment for metal surface treatment. Background Technology

[0002] Powder coating equipment is used to coat metal surfaces with a protective layer. It is widely used in fields such as corrosion prevention and enhanced wear resistance. Through standardized operating procedures, coating quality can be ensured, equipment life can be extended, and production efficiency can be improved.

[0003] Currently, existing powder coating equipment suffers from several drawbacks during use. The nozzles are prone to clogging, necessitating replacement. Replacing the nozzles often requires tools, which is time-consuming and labor-intensive, reducing the equipment's practicality. Furthermore, most existing equipment can only powder coat a single metal product at a time, resulting in low efficiency and further diminishing its usability. Therefore, there is an urgent need for a powder coating equipment specifically designed for metal surface treatment to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a powder coating equipment for metal surface treatment to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a powder coating equipment for metal surface treatment, comprising:

[0006] A powder-coated barrel, wherein a recycling structure is provided inside the outer surface of one side of the lower end of the powder-coated barrel, and a powder-coating structure is provided inside the powder-coated barrel; and an electric telescopic rod is installed on the outer surface of the other side of the powder-coated barrel, wherein a synchronous rotation structure is provided on the outer surface of one side of the upper end of the electric telescopic rod.

[0007] The recycling structure includes a collection bucket, which is inserted into the interior of the outer surface of the lower end of the powder-coated bucket.

[0008] The powder coating structure includes a flow divider ring, and the flow divider ring is installed inside the inner wall surface of the powder coating barrel;

[0009] The synchronous rotation structure includes a rotating chamber, and the outer surface of one side of the rotating chamber is fixedly connected to the outer surface of the upper end of the electric telescopic rod.

[0010] Preferably, the recycling structure further includes a threaded hole, which is opened inside the outer surface of the upper end of the collection bucket. A partition is attached to the outer surface of the upper end of the collection bucket, and a connecting block is fixedly connected to the bottom surface of one end of the partition. A bolt is threadedly connected to the inner surface of the outer surface of one side of the connecting block. A filter screen is installed inside the partition. This design allows the plastic powder splashed during the powder coating process inside the powder coating bucket to be collected inside the collection bucket.

[0011] Preferably, the inner wall surface of the threaded hole is adapted to the outer surface of one end of the bolt, and the filter screen is made of polyester fiber. This design can filter the plastic powder after use by utilizing the inherent characteristics of the filter screen.

[0012] Preferably, the outer surface of the diversion ring is connected to a connecting pipe, and multiple sets of connecting pipes are provided. The connecting pipe is equipped with a moving plate and a spring inside, and a nozzle is inserted into the inner surface of one end of the connecting pipe. The upper and lower surfaces of one end of the nozzle are fixedly connected with interlocking blocks. This design allows multiple metal products to be powder coated simultaneously through the design of multiple sets of connecting pipes.

[0013] Preferably, a rectangular groove is formed on the inner wall surface of the upper and lower ends of one end of the connecting pipe. The external dimensions of the interlocking block are adapted to the internal dimensions of the rectangular groove. The outer surfaces of both ends of the spring are respectively fixedly connected to the inner wall surface on one side of the connecting pipe and the surface on one side of the moving plate. One end of the nozzle is made of rubber. This design allows the interlocking block to be inserted into the rectangular groove, and the connection between the nozzle and the connecting pipe can be completed by rotating the nozzle.

[0014] Preferably, the synchronous rotation structure further includes a motor and a second gear. The motor is mounted on the top surface inside the upper end of the rotating chamber, and the output end of the motor is fixedly connected to a first gear. The outer surface of the first gear is meshed with a connecting gear. Multiple sets of second gears are provided, and the multiple sets of second gears are meshed with each other. The outer surface of one set of second gears in the multiple sets of second gears is meshed with the outer surface of the connecting gear. The lower outer surfaces of the multiple sets of second gears are all engaged with the inside of the bottom surface of the rotating chamber. A hook is fixedly connected to the bottom surface of the second gear. This design allows the output end of the motor to drive the first gear to rotate when the motor is started, and also causes multiple sets of second gears to rotate synchronously.

[0015] Preferably, a rubber sealing ring is fixedly connected to the outer side of the bottom surface of the rotating chamber, and the outer diameter of the rubber sealing ring is the same as the inner diameter of the powder coating barrel. This design can prevent the plastic powder generated inside the powder coating barrel from spreading outward.

[0016] The technical effects and advantages of this utility model are as follows: By rotating the nozzle, the position of the insert block corresponds to the position of the rectangular groove. At this time, the nozzle can be pushed outward under the elasticity of the spring, thereby disassembling the nozzle. The position of the insert block at the unused end of the nozzle corresponds to the position of the rectangular groove. The nozzle can then be inserted into the inside of the connecting pipe, so that the insert block is inserted into the rectangular groove. Rotating the nozzle causes the insert block to abut against the inner wall surface of one side of the connecting pipe under the elasticity of the spring. This completes the replacement of the nozzle without the need for tools, which is more time-saving and labor-saving, and improves the practicality of the device to a certain extent.

[0017] The metal products to be powder-coated are suspended inside multiple sets of hooks. Then, the electric telescopic rod can be activated to move downwards, allowing the metal products and hooks to enter the powder coating barrel. The rubber sealing ring is then inserted into the upper outer surface of the powder coating barrel. At this point, the motor can be activated to drive the connecting gears and multiple sets of second gears to rotate, thereby causing the hooks to rotate synchronously. This allows the metal products to rotate together, and multiple sets of spray nozzles can then powder-coate the surfaces of multiple sets of metal products. This method is highly efficient and avoids the scattering of powder, thus improving the practicality of the device to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The powder coating involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] like Figures 1-5 As shown in the figure, this embodiment proposes a powder coating equipment for metal surface treatment, including:

[0027] The powder-coated barrel 1 has a recycling structure 2 inside the outer surface of one side of the lower end of the powder-coated barrel 1, and a powder-coating structure 3 inside the powder-coated barrel 1. An electric telescopic rod 4 is installed on the outer surface of the other side of the powder-coated barrel 1, and a synchronous rotation structure 5 is installed on the outer surface of one side of the upper end of the electric telescopic rod 4.

[0028] The recycling structure 2 includes a collection bucket 21, which is inserted into the lower outer surface of the powder-coated bucket 1. The recycling structure 2 also includes a threaded hole 22, which is opened inside the upper outer surface of the collection bucket 21. A partition 23 is attached to the upper outer surface of the collection bucket 21, and a connecting block is fixedly connected to the bottom surface of one end of the partition 23. A bolt 24 is threadedly connected to the inner surface of the outer surface of one side of the connecting block. A filter screen 25 is installed inside the partition 23. The inner wall surface of the threaded hole 22 is adapted to the outer surface of one end of the bolt 24. The filter screen 25 is made of polyester fiber. This design allows the outer surface of one end of the bolt 24 to be threaded into the inside of the threaded hole 22, thereby completing the connection between the partition 23 and the collection bucket 21. At the same time, this design extends the service life of the filter screen 25 due to the good wear resistance and chemical corrosion resistance of the filter screen 25 itself.

[0029] The powder coating structure 3 includes a flow divider ring 31, which is installed inside the inner wall surface of the powder coating barrel 1. The outer surface of the flow divider ring 31 is connected to a connecting pipe 32, and multiple sets of connecting pipes 32 are provided. The connecting pipe 32 is equipped with a moving plate 33 and a spring 34 inside. A nozzle 35 is inserted into the inner surface of one end of the connecting pipe 32, and a matching block 36 is fixedly connected to the upper and lower surfaces of one end of the nozzle 35. A rectangular groove is opened on the inner wall surface of the upper and lower ends of one end of the connecting pipe 32. The external dimensions of the matching block 36 and the internal dimensions of the rectangular groove are adapted to each other. The outer surfaces of both ends of the spring 34 are fixedly connected to the inner wall surface on one side of the connecting pipe 32 and the surface on one side of the moving plate 33, respectively. One end of the nozzle 35 is made of rubber. This design allows the matching block 36 to be inserted into the rectangular groove. At the same time, this design allows the spring 34 to return to its original position after being squeezed. Furthermore, this design, through the good sealing and elasticity of the nozzle 35 material itself, can prevent the leakage of powder at the connection between the nozzle 35 and the connecting pipe 32.

[0030] Example 2

[0031] like Figure 4 and Figure 5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0032] The synchronous rotation structure 5 includes a rotating chamber 51, and the outer surface of one side of the rotating chamber 51 is fixedly connected to the outer surface of the upper end of the electric telescopic rod 4. The synchronous rotation structure 5 also includes a motor 52 and a second gear 55. The motor 52 is installed on the top surface inside the upper end of the rotating chamber 51, and the output end of the motor 52 is fixedly connected to a first gear 53. The outer surface of the first gear 53 is meshed with a connecting gear 54. There are multiple sets of second gears 55, and the multiple sets of second gears 55 are meshed with each other. The outer surface of one set of second gears 55 is meshed with the outer surface of the connecting gear 54. The outer surfaces of the lower ends of the multiple sets of second gears 55 are all engaged with the inside of the bottom surface of the rotating chamber 51. The bottom surface of the second gear 55 is fixedly connected to a hook 56. The outer side of the bottom surface of the rotating chamber 51 is fixedly connected to a rubber sealing ring, and the outer diameter of the rubber sealing ring is the same as the inner diameter of the spray-coated barrel 1.

[0033] In this embodiment, the design allows the rubber sealing ring to be inserted into the inner surface of the upper outer surface of the powder coating barrel 1, and the good sealing and elasticity of the rubber sealing ring itself can prevent the plastic powder inside the powder coating barrel 1 from spreading outward.

[0034] Working Principle: When using the device, first place it in a suitable position. Activate the electric telescopic rod 4 to move it upwards, simultaneously moving the rotating chamber 51 upwards. At this time, metal products can be suspended inside the multiple sets of hooks 56. Next, activate the electric telescopic rod 4 again to move it downwards, causing the rotating chamber 51 to fit against the outer surface of the upper end of the powder coating barrel 1. This allows the rubber sealing ring to be inserted into the inner surface of the upper end of the powder coating barrel 1, sealing the inside of the barrel 1. Then, activate the motor 52 to rotate the first gear 53, causing the connecting gear 54 to rotate simultaneously with multiple sets of second gears 55. This causes the hooks 56 to rotate along with the metal products. Subsequently, through external equipment, powder coating enters the diversion ring 31 and is applied to the surface of the metal products through multiple spray nozzles 35. The powder coating falls onto the outer surface of the upper end of the filter screen 25 for filtration. The filtered powder is then collected inside the collection bucket 21. After the metal products are coated, activate the electric telescopic rod 4 to move it downwards. The telescopic rod 4 moves upward, causing the rotating chamber 51 to move upward simultaneously. This allows the powder-coated metal product to be removed, and the collection bucket 21 to be pulled outward. The bolt 24 can be removed by rotating the thread. At this time, the partition 23 can be removed from the upper surface of the collection bucket 21, facilitating cleaning or replacement of the partition 23 and bolt 24. Simultaneously, the powder inside the collection bucket 21 can be poured back into the powder storage box, and the inside of the collection bucket 21 can be cleaned. When the nozzle 35 becomes clogged, rotating the nozzle 35 can be used to move the insert block 36 and the rectangular... The positions of the slots correspond, allowing the nozzle 35 to be disassembled. Then, the position of the unused nozzle 35 is aligned with the position of the insert block 36 and the rectangular slot. At this point, the nozzle 35 can be inserted into the inside of the connecting pipe 32, and the insert block 36 is inserted into the inside of the rectangular slot. Rotating the nozzle 35 causes the insert block 36 to engage inside the connecting pipe 32, and the elasticity of the spring 34 causes the insert block 36 to be pressed against the inner wall surface of one side of the connecting pipe 32. Thus, the nozzle 35 can be replaced. The above is the complete working principle of this utility model.

[0035] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0036] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0037] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
