Description

Technical Field

[0001] The present application relates to the technical field of surface treatment devices for resistance wire production, and specifically to a surface treatment device for resistance wire production. Background Art

[0002] Resistance wire is a common electrical component. Its main function is to convert electrical energy into internal energy. Resistance wire is widely used in temperature sensors and temperature regulators to measure and adjust the temperature of various equipment and systems. In order to prevent the resistance wire from short-circuiting due to bending or contact during use, a layer of paint is usually sprayed on the surface of the resistance wire to avoid direct contact between the resistance wires.

[0003] For example, a Chinese patent (publication number: CN215235332U) discloses a surface treatment device for resistance wire production, including a resistance wire processing substrate, a resistance wire guide roller group is provided above the resistance wire processing substrate, a drying base box is provided on one side of the resistance wire guide roller group, the resistance wire guide roller group can be used to guide and convey the resistance wire, the fixed frame can be used to clean the surface of the resistance wire passing through, the beveled annular rubber ring provided inside the fixed frame can be used to clean the surface of the resistance wire passing through the fixed frame, effectively remove debris on the surface of the resistance wire, and help to make the surface spray paint more uniform in the later stage, and the first drying structure and the second drying structure can be used to perform uniform hot air drying treatment on the surface of the resistance wire after spraying paint, so as to achieve rapid drying treatment of the paint sprayed on the surface of the resistance wire, and greatly shorten the working time of the resistance wire spraying paint.

[0004] However, the above-mentioned search patent still has some shortcomings. It sprays paint on the resistance wire through a paint spraying cylinder. When in use, the paint sprayed from the cylinder cannot all adhere to the surface of the resistance wire, so that part of the paint will fall on the inner wall of the cylinder and flow from both ends to the paint base box, causing waste. At the same time, if the fallen paint solidifies on the bottom wall of the paint spraying cylinder, it will also block the paint spraying holes of the paint spraying cylinder and thus affect the quality of the paint spraying, which is inconvenient to use. Therefore, a surface treatment device for resistance wire production is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a surface treatment device for resistance wire production, which has the advantages of less waste and good painting effect, and solves the problem that the device disclosed in the above-mentioned search patent easily causes waste of paint when used.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: A surface treatment device for resistance wire production, comprising a paint bin, a paint mechanism disposed on the paint bin, a drying bin fixed on the top surface of the paint bin, and a drying mechanism disposed on the drying bin;

[0007] The painting mechanism includes a first guide roller rotatably connected to the right inner wall of the paint bin, two second guide rollers rotatably connected to the inner bottom wall of the paint bin, a third guide roller rotatably connected to the inner top wall of the drying bin, a winding roller rotatably connected to the rear inner wall of the drying bin, and a paint scraping ring installed on the rear inner wall of the paint bin.

[0010] By adopting the above technical scheme, the painted resistance wire is guided by the painting mechanism and then enters the drying chamber. The resistance wire is heated by the drying tube and drying box arranged inside the drying chamber, thereby accelerating the drying speed of the paint on the surface of the resistance wire, thereby improving the treatment efficiency of the device on the surface of the resistance wire and further improving the practicality of the device.

[0011] Furthermore, the drying mechanism also includes an air intake pipe fixed to the air inlet end of the fan, a mounting ring threadedly connected to the inner wall of the air intake pipe, a limiting ring fixed to the inner wall of the air intake pipe, and a filter cartridge fixed to the left side of the mounting ring.

[0012] By adopting the above technical solution, when the fan is started, the air inside the drying bin will be sucked through the suction pipe, which is convenient for recycling the hot air inside the drying bin and reducing resource waste. When the suction pipe sucks air, the air will be filtered through the set filter cartridge to prevent dust from entering the drying box and adhering to the surface of the resistance wire paint. When the filter cartridge needs to be cleaned, the mounting ring can be turned to disengage it from the threaded connection of the suction pipe.

[0013] Furthermore, a rectangular hole is opened on the front of the paint bin, a discharge pipe is fixed on the left side of the paint bin near the bottom surface, and a sealing cover is threadedly connected to the left end of the discharge pipe.

[0014] By adopting the above technical solution, the rectangular hole is used to facilitate pulling the resistance wire through the first guide roller and the second guide roller during the equipment debugging stage, and the discharge pipe is used to facilitate replacement of paint that has been used for a long time.

[0015] Furthermore, the drying bin is a rectangular bin with openings on the bottom and the front, a sealed door is hinged on the front of the drying bin, and a glass observation window is installed on the front of the sealed door.

[0016] By adopting the above technical solution, the heat loss inside the drying chamber can be reduced by setting a sealed door, and at the same time, it is convenient to open the drying chamber for traction and guiding, disassembly of the winding roller, and other operations.

[0017] Furthermore, the two second guide rollers are distributed left and right, the second guide roller on the left side is opposite to the third guide roller up and down, the connecting hole is opposite to the paint scraper ring up and down, and the paint scraper ring is fixed to the paint bin by bolts.

[0018] The above technical solution makes it easy to move the resistance wire with paint on it upward, and then evenly apply the paint through the paint scraping ring, and make the excess paint flow along the resistance wire to the paint bin for recycling.

[0019] Furthermore, the drying box is a cylindrical box, the upper and lower ends of the drying tube are flush with the upper and lower sides of the drying box respectively, and the drying tube and the connecting hole are opposite to each other in the upper and lower directions.

[0020] The above technical solution makes it easy to allow the painted resistance wire to vertically penetrate the drying tube for drying.

[0021] Furthermore, the right end of the suction pipe extends into the drying chamber, and matching thread grooves are provided on the outer circumferential wall of the mounting ring and the inner circumferential wall of the suction pipe near the right side, and the left side of the mounting ring abuts against the right side of the limiting ring.

[0022] The above technical solution makes it easy to remove the filter cartridge for cleaning when necessary.

When the painting mechanism is painting, the heating lamp tube 403 is started to heat the inside of the drying box 401, so that the heating lamp tube 403 bakes the outer surface of the resistance wire. At the same time, the fan 404 is started.

When the fan 404 is started, the air inside the drying chamber 2 is sucked through the air intake pipe 407, which is convenient for recycling the hot air inside the drying chamber 2 and reducing resource waste. When the air intake pipe 407 inhales air, the air is filtered through the filter cartridge 410 to prevent dust from entering the drying box 401 and adhering to the surface of the resistance wire paint. When the filter cartridge 410 needs to be cleaned, the mounting ring 408 is rotated to disengage it from the threaded connection of the air intake pipe 407.
