[0003] There are usually two ways to apply epoxy powder to the powder. One is to collect the epoxy powder in a pool and soak the object to be applied with the powder in the epoxy powder pool to complete the powder application. The other is to hang the object and spray it with a spray gun to achieve the powder application. However, when using the above two methods to apply powder, powder will float in the air, which will affect the health of the operator.

[0026] The following is combined with Figures 1 to 4 The utility model is further introduced in detail.

[0027] An epoxy powder coating device, such as Figure 1 Figure 2 and Figure 3 As shown, it includes a shell 1 and placement ports 2 opened at both ends of the shell 1, specifically, one of the placement ports 2 is a feed port, and the other placement port 2 is a discharge port, and also includes: a spray chamber 3 arranged at the upper inner part of the shell 1, and spray guns 4 are symmetrically and evenly installed at both ends of the inner wall of the spray chamber 3. Further, the shape of the spray chamber 3 is an upward arch, and the spray guns 4 are installed in the spray chamber 3 at equal intervals along the circumferential direction. Further, a group of spray guns 4 can be installed in the spray chamber 3, and multiple groups of spray guns 4 can also be installed. An installation chamber 6 is arranged near the bottom of the spray chamber 3 inside the shell 1, and a conveying component 5 is rotatably installed inside the installation chamber 6. The conveying component 5 is used to convey the objects to be powdered placed from the feed port, and the spray gun 4 is used to powder-spray the objects on the conveying component 5. A storage chamber 7 is arranged near the bottom of the installation chamber 6 at the bottom of the shell 1, and the storage chamber 7 is used to collect excess powder after the spray gun 4 sprays the objects.

[0028] The transmission component 5 includes:

[0029] The transmission gear 52 is symmetrically mounted on both sides of the mounting cavity 6 for rotation.

[0030] The transmission chain belt 53 is installed on the two transmission gears 52 for common transmission. The transmission chain belt 53 is used for conveying the objects to be powdered.

[0031] The toggle block 54 is rotatably mounted at the middle position of the mounting cavity 6 , and the bottom of the toggle block 54 is clamped on the bottom of the transmission chain belt 53 . The toggle block 54 is used to vibrate the powder attached to the transmission chain belt 53 .

[0032] By placing the object on the transmission chain belt 53 and moving it to the position of the spray gun 4, the spray gun 4 sprays the object in all directions to achieve the purpose of powdering, and further improves the powdering effect of the object; and through the mutual cooperation between the transmission chain belt 53 and the toggle block 54, when the transmission chain belt 53 rotates, the toggle block 54 vibrates the remaining powder on the transmission chain belt 53, and then filters and collects the powder for re-spraying, thereby improving the utilization rate of the powder and further reducing the impact of the powder on the operator.

[0033] Specifically, Figure 2 and Figure 3 As shown, a filter plate 8 is installed between the installation chamber 6 and the storage chamber 7 , and the filter plate 8 is used to filter the powder dropped from the transmission chain belt 53 .

[0034] Furthermore, when the object is powder-sprayed, excess powder will be sprayed into the air or fall on the transmission chain 53, and then fall on the bottom of the installation cavity 6, and then the filter plate 8 will filter the fallen powder, and the powder with small particles will continue to fall downward through the filter plate 8, and the powder with large particles will remain on the filter plate 8. Since the filter plate 8 is inclined, the powder will not stay on the filter plate 8, and the powder remaining on the filter plate 8 will move out of the installation cavity 6.

[0035] Specifically, Figure 1 and Figure 2 As shown, a storage box 9 is installed on one side of the shell 1, and a feeding channel is opened inside the shell 1 near the bottom of the filter plate 8, and the output end of the feeding channel is connected to the storage box 9. The feeding channel is used to transport the powder on the filter plate 8 to the storage box 9.

[0036] Furthermore, when powder with larger particles remains on the filter plate 8, and because the filter plate 8 is inclined, the powder does not stay on the filter plate 8, and the powder remaining on the filter plate 8 moves to the storage box 9 through the feed channel, thereby collecting the powder with larger particles and improving the filtering effect of the filter plate 8.

[0037] Specifically, a material extraction pump is provided inside the housing 1 near the storage chamber 7 , and the output end of the material extraction pump transports the powder inside the storage chamber 7 to the spray gun 4 .

[0038] Furthermore, when in use, the pump delivers the powder in the storage chamber 7 to the spray gun 4, and then the spray gun 4 continuously sprays the powder to achieve the purpose of powdering.

[0039] Specifically, Figure 2 , Figure 3 and Figure 4 The transmission component 5 shown also includes:

[0040] The mounting rod 51 is symmetrically fixed at both ends of the mounting cavity 6, and two transmission gears 52 are installed at both ends of the mounting rod 51. Furthermore, one end of the mounting rod 51 is installed at the power output end of the driving motor, and the driving motor is installed inside the shell 1 near a group of mounting rods 51. Furthermore, the driving motor is externally connected to a power supply and a control panel.

[0041] The fixing plate 55 is fixedly connected to the inside of the installation cavity 6 near the upper part of the toggle block 54 .

[0042] There are multiple springs 56 , which are fixed to the fixing plate 55 and the upper part of the shifting block 54 at equal intervals.

[0043] Furthermore, when the transmission chain 53 rotates, the transmission chain 53 will drive the toggle block 54 to move up and down, and then the toggle block 54 will knock on the transmission chain 53 under the reaction force of the spring 56, thereby shaking the powder on the transmission chain 53 to the bottom of the installation cavity 6.

[0044] Specifically, both sides of the inner circle of the transmission chain belt 53 are provided with slots adapted to the movable track corresponding to the position of the transmission gear 52 .

[0045] Furthermore, the driving motor drives the two transmission gears 52 to rotate via the mounting rod 51 , and then the two transmission gears 52 drive the transmission chain 53 to rotate, thereby improving the rotation stability of the transmission chain 53 .

[0046] How it works

[0047] When in use, the object to be powdered is placed from a placement port 2 which is a feed port onto the transmission chain belt 53. At this time, the driving motor drives the two transmission gears 52 to rotate through the mounting rod 51, and then the two transmission gears 52 drive the transmission chain belt 53 to rotate, and then the transmission chain belt 53 moves the object to the position of the spray gun 4. At this time, the spray gun 4 sprays all directions of the object to achieve the purpose of powdering. When the powder falls on the transmission chain belt 53, when the transmission chain belt 53 rotates, the transmission chain belt 53 drives the toggle block 5 4 rotates, and then the toggle block 54 knocks the transmission chain belt 53 under the reaction force of the spring 56, so that the powder on the transmission chain belt 53 is shaken and falls to the bottom of the installation cavity 6. When the powder falls on the filter plate 8, the powder with small particles continues to fall downward through the filter plate 8, and the powder with large particles remains on the filter plate 8. Since the filter plate 8 is inclined, the powder does not stay on the filter plate 8. The powder remaining on the filter plate 8 moves to the storage box 9 through the feeding channel, so that the powder with larger particles is collected.

[0048] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
