Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically a steel wire surface coating machine. Background Technology

[0002] Steel wire is one of the four major types of steel products: plates, pipes, profiles, and wires. It is a reprocessed product made from hot-rolled wire rods through cold drawing. According to the cross-sectional shape, steel wire is mainly classified into round, square, rectangular, triangular, elliptical, flat, trapezoidal, and Z-shaped shapes. The main processes in steel wire production include raw material selection, removal of iron oxide scale, drying, coating treatment, heat treatment, wire drawing, and plating treatment.

[0003] Steel wire coating treatment involves applying a strong, thin film coating to the surface of wire rod or intermediate wire billet after removing iron oxide scale. This coating is made of a substance that has certain lubricating properties, especially during drawing, and can effectively absorb and carry lubricant into the deformation zone. Therefore, the coating is essentially a carrier of lubricant. The purpose of the coating is to create good lubrication conditions for drawing, thereby reducing friction and heat generation during the drawing process.

[0004] A search revealed Chinese patent CN116408239A, which discloses a coating device for the surface of tire bead wires. The device includes a coating box with a vertically mounted partition inside. A coating chamber is located within the coating box on one side of the partition. An extrusion frame is rotatably mounted on the upper side of the coating chamber via a hinge shaft. A swinging mechanism for extruding and conveying the tire bead wires is located at the bottom of the extrusion frame. A power mechanism for driving the extrusion frame to swing within the coating chamber is located on the upper side of the coating box. A drying mechanism for driving a drying chamber to spray hot gas is located on the upper side of the coating box. A spraying box is also installed on the upper side of the coating chamber, and a spraying mechanism for driving the spraying box to spray the coating agent is located on the upper side of the coating box. This invention allows the tire bead wires to be subjected to a certain degree of extrusion during the coating process, thereby ensuring that the coating agent is fully applied to the tire bead wires. Simultaneously, it allows the tire bead wires to be quickly dried after coating.

[0005] However, the above design still has shortcomings. In the above design, the coating effect of steel wire is improved by hot drying of the coated steel wire. However, after the steel wire is hot dried, the thermal stress on the coating surface is strong due to the lack of timely cooling treatment, which will reduce the overall quality of the coating.

[0006] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a steel wire surface coating machine to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a steel wire surface coating machine, comprising a housing, a movable door rotatably disposed on the front end face of the housing, a vent hole penetrating the surface of the movable door, a first filter screen fixedly disposed inside the vent hole, a control panel fixedly installed on the top left side of the housing, and a coating chamber, a heat treatment chamber, and a cold treatment chamber arranged sequentially from left to right by multiple partitions inside the housing, a second guide hole connecting the coating chamber and the heat treatment chamber, a first guide hole connecting the heat treatment chamber and the cold treatment chamber, a discharge port connecting the cold treatment chamber on the right side, and air outlets connecting the two sides of the top of the heat treatment chamber, a fourth filter screen fixedly disposed inside the air outlet. A mounting box is fixedly connected to the top of the heat treatment chamber on the upper surface of the housing. A fixing cavity is provided inside the mounting box. Heating blocks are fixedly installed on both sides of the inner wall of the fixing cavity. An air inlet is opened at the top of the fixing cavity, and a third filter is fixedly installed inside the air inlet. An air pump is installed at the bottom of the fixing cavity, and the input end of the air pump is connected to the interior of the fixing cavity via a pipe. A conduit is fixedly connected to the output end of the air pump, and the conduit is located at the top of the interior of the heat treatment chamber. Multiple nozzles are fixedly connected to the bottom of the conduit. A through groove is opened at the top of the cold treatment chamber, and a second filter is fixedly installed inside the through groove. A support plate is fixedly connected to the lower interior of the cold treatment chamber, and a fan is fixedly installed on the top of the support plate.

[0009] As a further embodiment of this utility model: a connected feed inlet is provided on the left side of the coating chamber, and a connected feeding pipe is fixedly provided on the top of the coating chamber, with a limiting cover movably provided at the opening of the feeding pipe.

[0010] As a further embodiment of this utility model: a discharge pipe is fixedly provided at the lower left side of the coating cavity, and a threaded cap is provided at the pipe opening of the discharge pipe.

[0011] As a further embodiment of this utility model: a first guide wheel is rotatably arranged on the upper left side of the inner wall of the coating cavity, a plurality of second guide wheels are rotatably arranged on the bottom of the inner wall of the coating cavity, and a fourth guide wheel is rotatably arranged on the upper right side of the inner wall of the coating cavity.

[0012] As a further embodiment of this utility model: a sleeve is fixedly connected to the inner top of the coating cavity, a spring is fixedly connected to the inner top of the sleeve, and a connecting rod is fixedly connected to the bottom of the spring through a connecting block.

[0013] As a further embodiment of this utility model: a connecting plate is fixedly connected to the bottom of the connecting rod, and a third guide wheel is installed at the bottom of the connecting plate.

[0014] This utility model has the following beneficial effects:

[0015] The structural design, consisting of a first filter, vent, second filter, channel, fan, support plate, third filter, fixed cavity, air pump, conduit, nozzle, air inlet, heating block, fourth filter, and air outlet, facilitates both hot drying of the steel wire and cold treatment of the dried wire. This eliminates thermal stress and improves the overall quality and durability of the coating. It solves the problem that while hot drying improves the coating effect, the lack of timely cold treatment after hot drying leads to strong thermal stress on the coating surface, reducing the overall quality of the coating.

[0016] Through the structural design of the first guide wheel, second filter screen, sleeve, connecting rod, third guide wheel, spring, connecting plate and fourth guide wheel, the steel wire can be conveyed and moved, and the steel wire can be coated. The operation is simple and the coating effect is good. At the same time, the cooperation of the third guide wheel and the fourth guide wheel can not only guide the steel wire, but also, due to the elasticity of the spring, can generate a certain squeezing force on the coated steel wire, which can squeeze off the excess coating on the surface of the steel wire, thereby improving the coating effect of the steel wire.

For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0027] Please see Figure 1-4 This utility model provides an embodiment of a steel wire surface coating machine, comprising a housing 4, a movable door 11 rotatably disposed on the front end face of the housing 4, a vent 10 penetrating through the surface of the movable door 11, a first filter 9 fixedly disposed inside the vent 10, a control panel 3 fixedly installed on the top left side of the housing 4, and a coating chamber 12, a heat treatment chamber 23, and a cold treatment chamber 17 arranged sequentially from left to right through multiple partitions inside the housing 4, a second guide hole 22 connecting the coating chamber 12 and the heat treatment chamber 23, a first guide hole 19 connecting the heat treatment chamber 23 and the cold treatment chamber 17, a discharge port 18 connecting to the right side of the cold treatment chamber 17, and air outlets 38 connecting to both sides of the top of the heat treatment chamber 23, a fourth filter 37 fixedly disposed inside the air outlet 38, and the heat treatment chamber 23... A mounting box 8 is fixedly connected to the top surface of the housing 4. The mounting box 8 has a fixed cavity 31 inside. Heating blocks 36 are fixedly installed on both sides of the inner wall of the fixed cavity 31. The top of the fixed cavity 31 has a connected air inlet 35. A third filter screen 30 is fixedly installed inside the air inlet 35. An air pump 32 is installed at the bottom of the fixed cavity 31. The input end of the air pump 32 is connected to the inside of the fixed cavity 31 through a pipe. The output end of the air pump 32 is fixedly connected to a conduit 33. The conduit 33 is located at the top of the heat treatment chamber 23. Multiple nozzles 34 are fixedly connected to the bottom of the conduit 33. A through groove 16 is opened at the top of the cold treatment chamber 17. A second filter screen 15 is fixedly installed inside the through groove 16. A support plate 21 is fixedly connected to the lower end of the inside of the cold treatment chamber 17. A fan 20 is fixedly installed on the top of the support plate 21.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, during use, after the steel wire coating is completed, the air in the fixed cavity 31 can be heated by the heating block 36, and then the heated air is blown into the duct 33 by the air pump 32, and finally sprayed out through multiple nozzles 34, thereby achieving hot drying of the steel wire. At the same time, the wind generated by the rotation of the fan 20, together with the vent 10 and the through groove 16, can draw cold air from the outside into the cold treatment cavity 17, and then perform cold treatment on the hot-dried steel wire, thereby effectively reducing thermal stress and improving the overall quality and durability of the coating. This solves the problem that while hot drying of the coated steel wire can improve the coating effect, the lack of timely cold treatment after the hot drying process leads to strong thermal stress on the coating surface, which reduces the overall quality of the coating.

[0029] A feed inlet 5 is provided on the left side of the coating chamber 12. A feed pipe 2 is fixedly provided on the top of the coating chamber 12. A limiting cover 1 is movably provided at the opening of the feed pipe 2. A discharge pipe 7 is fixedly provided on the lower left side of the coating chamber 12. A threaded cover 6 is provided at the opening of the discharge pipe 7. A first guide wheel 13 is rotatably provided on the upper left side of the inner wall of the coating chamber 12. Multiple second guide wheels 14 are rotatably provided on the bottom inside of the coating chamber 12. A fourth guide wheel 29 is rotatably provided on the upper right side of the inner wall of the coating chamber 12. A sleeve 24 is fixedly connected to the top inside of the coating chamber 12. A spring 27 is fixedly connected to the top inside of the sleeve 24. A connecting rod 25 is fixedly connected to the bottom of the spring 27 through a connecting block. A connecting plate 28 is fixedly connected to the bottom of the connecting rod 25. A third guide wheel 26 is installed at the bottom of the connecting plate 28.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, the steel wire can be conveyed and moved by the cooperation of the first guide wheel 13, the second guide wheel 14, the third guide wheel 26, and the fourth guide wheel 29. When the steel wire is located between the multiple second guide wheels 14, the coating cavity 12 is filled with coating material, thereby achieving coating of the steel wire. The operation is simple and the coating effect is good. At the same time, the cooperation of the third guide wheel 26 and the fourth guide wheel 29 can not only guide the steel wire, but also, due to the elasticity of the spring 27, can generate a certain squeezing force on the coated steel wire, which can squeeze off the excess coating material on the surface of the steel wire, thereby improving the coating effect of the steel wire.

[0031] Working Principle: In this application, when steel wire needs to be coated, the movable door 11 is first opened. Then, the steel wire to be coated is sequentially passed through the feed inlet 5, the first guide roller 13, the second guide roller 14, the third guide roller 26, and the fourth guide roller 29, the second guide hole 22, and the first guide hole 19. Finally, it exits through the discharge port 18 and is fixed to the external take-up roller. The movable door 11 is then closed, and an appropriate amount of coating is added to the coating chamber 12 through the feeding pipe 2. As the take-up roller rotates, the steel wire moves slowly within the housing 4. During this process, the steel wire can be conveyed and moved through the cooperation of the first guide roller 13, the second guide roller 14, the third guide roller 26, and the fourth guide roller 29. When the steel wire is located between multiple second guide rollers 14, the coating chamber 12 is filled with coating material, thus achieving coating of the steel wire. The operation is simple and efficient. The coating effect is good. Through the cooperation of the third guide wheel 26 and the fourth guide wheel 29, the steel wire can be guided. Due to the elasticity of the spring 27, a certain squeezing force can be generated on the coated steel wire to squeeze off the excess coating on the surface of the steel wire, thereby improving the coating effect of the steel wire. Secondly, after the steel wire coating is completed, the air in the fixed cavity 31 can be heated by the heating block 36, and then the heated air is blown into the duct 33 by the air pump 32. Finally, it is sprayed out through multiple nozzles 34 to achieve heat drying of the steel wire. At the same time, the wind generated by the rotation of the fan 20, together with the vent 10 and the through groove 16, can draw cold air from the outside into the cold treatment cavity 17 and then perform cold treatment on the heat-dried steel wire, thereby eliminating thermal stress and improving the overall quality and durability of the coating.
