[0005] In the spraying process of the existing spraying device, the diffusion speed of epoxy resin paint is too fast. This causes the paint liquid to spread rapidly after contacting the surface of the object, resulting in a short spraying effect time. The paint liquid cannot fully penetrate and adhere to the surface of the object, which is prone to problems such as uneven coating and inconsistent thickness. Moreover, the excessively fast diffusion speed may also lead to waste of paint liquid, increasing production costs.

[0006] In view of the above problems, a corrosion-resistant epoxy resin paint spraying device is proposed. Summary of the invention

Secondly, the driving motor drives the driving disk to rotate, and then drives the workpiece to be sprayed to rotate in a cycle, so that the epoxy resin can be better sprayed to various parts of the workpiece to be sprayed, ensuring the flatness of the paint surface. Furthermore, the setting of the polymerization component greatly improves the utilization rate of the paint liquid.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0030] Combination Figure 1-Figure 5 , a corrosion-resistant epoxy resin paint spraying device of the present invention comprises a support frame 11, a spraying chamber 12 is connected to the top of the support frame 11, and a driving motor 13 is also arranged inside the support frame 11;

[0031] The output end of the driving motor 13 is connected to a positioning assembly 3, which includes a driving disk 31. The driving disk 31 and the output end of the driving motor 13 are connected together. The output end of the driving motor 13 passes through the spray chamber 12 and is connected to the driving disk 31. The driving disk 31 is embedded in the interior of the spray chamber 12 and keeps a rotation connection. A sliding groove 34 is provided on the driving disk 31. A lifting rod 32 is embedded in the sliding groove 34. A pushing screw 35 is connected to the bottom end of the lifting rod 32. The bottom end of the driving disk 31 is connected to a fixed block. A pushing screw 35 is embedded in the fixed block. A positioning slot 33 is provided on the lifting rod 32. Three groups of sliding grooves 34 are provided on the upper surface of the driving disk 31. A lifting rod 32 is embedded in each group of sliding grooves 34. The pushing screw 35 passes through the fixed block until it passes through the bottom end of the lifting rod 32. The pushing screw 35 is rotationally connected to the fixed block and the lifting rod 32. The interior of the positioning slot 33 is embedded with the part to be sprayed 14.

[0032] When spraying the workpiece 14, the workpiece 14 needs to be fixed first. The workpiece 14 is embedded in the positioning slot 33, and then the advancing screw 35 is rotated to make the three groups of lifting and extending rods 32 approach each other. The workpiece 14 is clamped by the positioning slot 33 through the approach of the lifting and extending rods 32. After being clamped, the position of the workpiece 14 is more stable.

[0033] When the workpiece 14 to be sprayed is fixed in the positioning slot 33, the workpiece 14 to be sprayed corresponds to the middle position between the spray inlet pipe 21 and the spray outlet pipe 22, that is, when the paint liquid is introduced from the inside of the spray inlet pipe 21 into the inside of the spray chamber 12, the paint liquid can be sprayed onto the upper surface and the lower surface of the workpiece 14 to be sprayed;

[0034] In order to make the paint surface smooth, the driving motor 13 starts to work, and the driving motor 13 drives the driving disc 31 to rotate. After the driving disc 31 rotates, it drives the workpiece 14 to be sprayed to rotate, and the epoxy resin is better sprayed onto the workpiece 14 through the circular rotation;

[0035] During the spraying of epoxy resin, the paint liquid will float in the air and eventually diffuse with the flow of air, which will cause part of the paint liquid to be wasted. In order to avoid this problem, a polymerization component 2 is provided to make the paint liquid more concentrated during the spraying process; the specific operation is as follows:

[0036] A polymerization component 2 is connected to one side of the spraying bin 12, and the polymerization component 2 includes a spraying inlet pipe 21. One side of the spraying bin 12 is connected to the spraying inlet pipe 21, and the other side is connected to the spraying outlet pipe 22. The interiors of the spraying inlet pipe 21 and the spraying outlet pipe 22 are both embedded with a partition plate 23, and the partition plate 23 is used to separate the interior of the spraying inlet pipe 21 or the spraying outlet pipe 22. The partition plate 23 divides the interior of the spraying inlet pipe 21 or the spraying outlet pipe 22 into two independent spaces. A pressing plate 24 is provided at the top of the spraying bin 12. The pressing plate 24 is embedded at the top of the spraying bin 12, and the pressing plate 24 is slidably connected to the spraying bin 12. A guide piece 25 is connected to the inner wall of the spraying bin 12. The guide piece 25 is arranged on the inner wall close to the side of the spraying bin 12. The guide piece 25 is arranged in an arc shape. A gap for air to pass through is reserved between each group of guide pieces 25, and the guide piece 25 is bent toward one side of the part 14 to be sprayed.

[0037] The epoxy resin spray is transported from the spray inlet pipe 21 to the inside of the spray chamber 12 , and is output through the partition plate 23 after passing through the inside of the spray chamber 12 .

[0038] After the workpiece 14 to be sprayed is fixed, the epoxy resin is sprayed onto the workpiece 14 to prevent the paint from randomly scattering. First, the spray inlet pipe 21 sprays the paint into the interior of the spray chamber 12. At this time, the interior of the spray chamber 12 is relatively narrow, and the paint will not spread easily. During the spraying process, the air will be driven to flow. At this time, the air is guided by the guide plate 25 to gather toward the direction of the workpiece 14 to be sprayed, so that the paint accompanying the air can also be guided to a certain extent, so that the paint can be more gathered.

[0039] First, the utilization rate of the paint liquid is improved. Since the paint liquid is not easy to diffuse in a relatively small space, and the air guide makes it more concentrated, the waste of the paint liquid is reduced, and the production cost is reduced. Secondly, the spraying quality is guaranteed. The concentration and orderly flow of the paint liquid make the spraying more uniform and can better cover the target object, especially for objects with complex shapes, such as parts with curved surfaces, corners or small gaps, a good spraying effect can also be achieved. In addition, the safety of the working environment is enhanced. The random dispersion of the paint liquid is reduced, and the potential harm of the paint liquid to the health of the operator and the pollution to the surrounding environment are reduced. Finally, the production efficiency is improved. The controllable paint liquid spraying process reduces the number of repeated spraying and shortens the time of the spraying operation.
