Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, specifically to a heat film device for processing anti-corrosion steel. Background Technology

[0002] Corrosion-resistant steel is specially treated steel to resist corrosion and oxidation, and is widely used in construction, bridges, chemical industries, transportation, and other fields. Its corrosion resistance is typically enhanced through coatings, hot-dip galvanizing, or alloy design. A hot-film processing device for corrosion-resistant steel involves heating the steel and then applying a polyethylene film to its surface. This device uses heat to create a tight bond between the polyethylene film and the steel surface, forming an effective protective layer that prevents the intrusion of moisture, oxygen, and other corrosive substances. This technology not only enhances the corrosion resistance of the steel but also improves its aesthetics and extends its service life.

[0003] Existing hot-film processing devices for anti-corrosion steel typically use electric heating devices to heat the surface of the steel, followed by further heating with multiple heating rollers. Then, a pressing roller is used to heat-press a polyethylene film onto the surface of the steel. However, when the steel is fed into the heating device, dust and particles adhering to the surface of the steel are easily detached and accumulate inside the heating device when heated. This dust and particles adhering to the inner wall of the heating device affects the heat transfer efficiency of the device, thus affecting the normal heating efficiency of the steel. To address this, we propose a hot-film processing device for anti-corrosion steel. Utility Model Content

[0004] The purpose of this invention is to provide a heat film device for processing anti-corrosion steel, so as to solve the problem mentioned in the background art that dust and particulate matter attached to the surface of steel fall off into the heater and affect the normal heating of the heater.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot film processing device for anti-corrosion steel, comprising a support frame one, a feeding roller at the top of the support frame one, a fixing member on the side wall of the feeding roller, a heating device on the side wall of the fixing member, a support frame two on one side wall of the support frame two, multiple heating rollers inside the support frame two, multiple loading shafts mounted on the side wall of the heating rollers, a pressing roller cooperating with the loading shafts at the rear end of the support frame two, a cooling member on the side wall of the pressing roller, a dust filter element snapped into the fixing member, an air hole on the outer wall of the dust filter element that cooperates with the interior of the fixing member, an air pipe at the output end of the dust filter element, and an air pump at the output end of the air pipe.

[0006] Preferably, the side wall of the dust filter element is provided with a rotating plate rotatably connected to the fixed element, and the side wall of the dust filter element is machined with a snap-fit ​​groove.

[0007] Preferably, an adjusting member extends through the side wall of the fixing member, and a rotating screw extends through the side wall of the adjusting member.

[0008] Preferably, the adjusting member has a mating cavity inside, and a steel wheel is provided on the side wall of the adjusting member.

[0009] Preferably, the top of the adjusting member has a rotating shaft that fits into the steel wheel, and the side wall of the adjusting member is provided with a threaded hole that fits into the rotating screw.

[0010] Preferably, the heater has an internal cavity, and a limiting block connected to the bracket is fixed to the side wall of the heater.

[0011] Preferably, the second side wall of the bracket is provided with an operating port that matches the loading shaft, and the cooling component is fixed to the side wall of the second bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting a fixing component with a dust filter between the heating appliance and the feeding roller, allows the air pump to operate when the anti-corrosion steel is fed into the heating appliance for heating. This causes the air pipe to draw air into the dust filter, and the air holes draw air into the surface of the steel. This draws dust or particles adhering to the steel surface into the interior of the filter. By rotating the rotating plate outward, the dust filter can be pulled out for cleaning. This effectively cleans the dust or particles adhering to the surface of the steel, preventing dust or particles from falling into the heating appliance during heating and adhering inside, which would affect the heating efficiency of the heating appliance. This is beneficial for the long-term heating and use of the steel.

[0014] 2. In this utility model, when the steel material is fitted inside the fixing component, the steel material is located on the side wall of the steel wheel of the adjusting component. This allows the rotating screw to be rotated, causing the adjusting component to move and thus the steel wheel to move as well. At this time, the side wall of the steel material will be pushed and translated by the steel wheel. This allows the adjusting component to be used in conjunction with the steel wheel to push the steel material to adjust its position when the steel material is conveyed between the feeding roller and the heating device and becomes skewed. This avoids the steel material from becoming skewed and causing cutting problems to the inner wall of the heating device, and is beneficial for the stable heat-applied film processing of the steel material.

A dust filter element 122 is internally engaged with a fixing element 120. The outer wall of the dust filter element 122 has air holes 123 that fit inside the fixing element 120. Inside the dust filter element 122 is a stainless steel dust filter mesh that fits into the air holes 123. The mesh surface is covered with numerous fibers, allowing dust to adhere through the gaps in the fibers. An air pipe 101 is mounted at the output end of the dust filter element 122. The air pipe 101 uses a commonly available flexible inner wall. A plastic tube with embedded stainless steel wire is provided. An air pump 102 is provided at the output end of the air pipe 101. The air pump 102 is a common model on the market. When applying film to steel, the steel can be fed into the heating device 110 by the feeding roller 111. Then the steel is sent to the top of the left heating roller 131, then to the bottom of the middle heating roller 131, and then to the top of the left heating roller 131. At this time, the polyethylene film take-up drum is installed on the upper and lower feeding shafts 132. Then the steel passes between the two feeding shafts 132 and the polyethylene film is applied to both sides of the steel. After that, it is pressed by the pressing roller 133 and then cooled by the cooling component 134.

[0024] Specifically, the side wall of the dust filter 122 is provided with a rotating plate 121 that is rotatably connected to the fixing member 120. The top of the rotating plate 121 is provided with a slot, and the inner wall of the fixing member 120 is provided with an inverted triangular elastic card that cooperates with the slot. The rotating plate 121 can be engaged when it rotates back to the side wall of the fixing member 120. The side wall of the dust filter 122 is machined with a engaging groove 124.

[0025] Furthermore, an adjusting member 140 extends through the side wall of the fixing member 120, and a rotating screw 141 extends through the side wall of the adjusting member 140.

[0026] Furthermore, the adjusting member 140 has a mating cavity 142 inside, the rotating screw 141 is mated to the mating cavity 142, the rotating screw 141 is rotatably connected to the side wall of the fixing member 120, and the side wall of the adjusting member 140 is provided with a steel wheel 143.

[0027] Furthermore, the top of the adjusting member 140 has a rotating shaft 144 that fits with the steel wheel 143, and the side wall of the adjusting member 140 is provided with a threaded hole 145 that fits with the rotating screw 141.

[0028] It is worth noting that the heating appliance 110 has an internal cavity, and a limiting block connected to the bracket 100 is fixed to the side wall of the heating appliance 110.

[0029] It is worth noting that the side wall of the second bracket 130 is provided with an operation port that matches the loading shaft 132. The cooling component 134 is fixed to the side wall of the second bracket 130. The side wall of the cooling component 134 is provided with a commercially available axial flow fan, which can cool the steel after it is pressed by the pressing roller 133.

[0030] In addition, all the electrical components and equipment mentioned above use external power sources. The circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0031] Working principle: By setting a fixing member 120 with a dust filter element 122 between the heating appliance 110 and the feeding roller 111, when the anti-corrosion steel is fed into the heating appliance 110 for heating with the feeding roller 111, the air pump 102 operates, causing the air pipe 101 to draw air into the dust filter element 122. At this time, the air hole 123 draws air into the surface of the steel, thereby drawing dust or particles attached to the surface of the steel into the interior of the filter element. By rotating the rotating plate 121 outward, the dust filter element 122 can be pulled out for cleaning. This achieves the cleaning of dust or particles attached to the surface of the steel, preventing dust or particles from falling into the heating appliance 110 and adhering to the interior of the heating appliance 110 during steel heating. The occurrence of problems affecting the heating efficiency of the heating appliance 110 is beneficial for the long-term heating use of steel. When the steel is fitted inside the fixing part 120, the steel is located on the side wall of the steel wheel 143 of the adjusting part 140. This allows the rotating screw 141 to rotate, causing the adjusting part 140 to move and thus causing the steel wheel 143 to move as well. At this time, the side wall of the steel will be pushed and translated by the steel wheel 143. This allows the adjusting part 140 to be used in conjunction with the steel wheel 143 to push the steel to adjust its position when the steel is skewed during the conveying between the feeding roller 111 and the heating appliance 110. This avoids the steel from being skewed and causing cutting problems to the inner wall of the heating appliance 110, and is beneficial for the stable heat-applied film processing of the steel.
