Technical Field
[0001] This invention relates to the field of color-coated steel sheet production technology, specifically to an automatic production equipment for negative ion color-coated steel sheets. Background Technology
[0002] Color-coated steel sheets combine the high strength of steel with the corrosion resistance and aesthetic appeal of organic coatings, making them widely used in factory enclosures, prefabricated buildings, and appliance housings. With increasing demands for healthy living environments and indoor air purification, the market demand for color-coated steel sheets with negative ion functionality—which can sustainably release negative ions and eliminate static electricity-adsorbed dust—continues to grow.
[0003] Existing color-coated steel sheet production equipment lacks a dedicated piercing needle venting mechanism. After lamination, the air trapped between the sheet and the protective film cannot be effectively discharged. Relying solely on a single pressure roller is insufficient to remove the internal air accumulation, easily causing bulges. Lamination wrinkles cannot be eliminated, resulting in an uneven finished sheet surface and a high defect rate. Furthermore, there is a lack of an anti-static spraying mechanism linked to the piercing station, so static electricity generated during sheet processing cannot be eliminated simultaneously, resulting in poor anti-static performance. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an automatic production equipment for negative ion color-coated steel sheets, which solves the problems of traditional color-coated steel sheet equipment lacking a dedicated piercing needle exhaust structure, resulting in easy blistering and wrinkling of the coating, low yield, and the lack of an anti-static spraying device linked with the piercing station, which prevents the synchronous removal of static electricity from the sheet material and leads to poor anti-static effect.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic production equipment for negative ion color-coated steel sheets, comprising a frame, with support blocks symmetrically fixedly connected to the top of the frame, and a fixed frame fixedly connected to the top of the two support blocks. The fixed frame has symmetrically opened rod holes on its top, and guide rods are slidably connected within the rod holes. Mounting plates are fixedly connected to the bottom of the two guide rods, and needles are evenly distributed at the bottom of the mounting plates. A sliding hole is opened in the middle of the fixed frame, and a lifting rod is slidably connected within the sliding hole. The bottom end of the lifting rod is fixedly connected to the top of the mounting plate, and a rod cap is fixedly connected to the top of the lifting rod. A spring is fixedly connected to the side of the rod cap opposite to the fixed frame. A motor is mounted on the top of the fixed frame, and a cam is fixedly connected to the output end of the motor. Auxiliary rollers are symmetrically rotatably connected to the sides of the two support blocks opposite to each other. An antistatic assembly is mounted on the top of the fixed frame. A cleaning assembly, a blowing and heating assembly, and a pressure roller assembly are sequentially mounted on the top of the frame.
[0006] By adopting the above technical solution, the motor drives the cam to rotate, and the outer edge of the cam protrudes downwards periodically, pressing the rod cap. This causes the lifting rod to move the mounting plate and the needles at its bottom downwards synchronously. When the cam protrusion passes the rod cap, the pressing force disappears, and the rod cap, lifting rod, and mounting plate move upwards as a whole. The needles move upwards synchronously. As the cam continues to rotate, the needles move up and down repeatedly, thus piercing the film on the color steel plate. This punctures and releases the air trapped between the film and the plate. The rear end is equipped with an elastic pressure roller assembly, and spring four makes the pressure roller adaptively fit the plate and roll it flat. The tiny air bubbles remaining after piercing are squeezed out along the micropores, and the film wrinkles are simultaneously flattened and eliminated. This solves the appearance defects such as film bulges and wrinkles in the finished product, resulting in a smooth and flat finished plate surface and improving the quality of the finished color steel plate.

[0016] This invention provides an automated production line for negative ion color-coated steel sheets. It has the following beneficial effects:
[0017] 1. This invention utilizes a motor to drive a cam to rotate. The cam's outer edge protrusion periodically presses the rod cap downwards, causing the lifting rod to move the mounting plate and its bottom needles downwards synchronously. When the cam's protrusion passes the rod cap, the pressing force disappears, and the rod cap, lifting rod, and mounting plate move upwards as a whole. The needles move upwards synchronously. As the cam continues to rotate, the needles move up and down repeatedly, thus piercing the film coated on the color steel plate, puncturing and expelling the air trapped between the film and the plate. A flexible pressure roller assembly is provided at the rear end, and spring four makes the pressure roller adaptively fit the plate and roll it flat. The remaining tiny air bubbles from the piercing are squeezed out along the micropores, and the film wrinkles are simultaneously flattened and eliminated, solving the appearance defects such as film bulges and wrinkles in the finished product. The finished plate surface is flat and smooth, improving the quality of the finished color steel plate.
[0018] 2. In this invention, during the rotation of the cam, the round cap is pressed synchronously and periodically, causing the piston rod to drive the piston block to reciprocate up and down within the sleeve. When the piston block moves down, the first one-way valve on the air inlet pipe opens, and the second one-way valve on the air delivery pipe closes, allowing external gas to enter the sleeve through the air inlet pipe. When the piston block moves up, the first one-way valve on the air inlet pipe closes, and the second one-way valve on the air delivery pipe opens, pushing the gas in the sleeve into the air delivery pipe, then into the hollow tube, and finally out through the nozzle. The negative ion antistatic coating stored in the storage cylinder is mixed and atomized under the negative pressure of the high-pressure airflow, and is evenly sprayed onto the surface of the color steel plate along with the airflow, completing the antistatic treatment of the plate surface, eliminating the problem of static electricity adsorption of dust on the plate, and improving the antistatic function of the color-coated plate.
[0019] 3. This invention, by setting a cleaning component at the front end, uses upper and lower cleaning rollers for mechanical wiping combined with high-pressure airflow for dual dust removal, which can effectively remove floating dust, metal debris and stubborn oil stains from the board surface. It solves the problems of incomplete cleaning in traditional pretreatment, resulting in particles, poor adhesion, peeling and flaking of the subsequent negative ion coating, thus improving the coating adhesion performance and the appearance quality of the finished board surface.

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Please see the appendix Figure 1 -Appendix Figure 10This invention provides an automatic production equipment for negative ion color-coated steel sheets, including a frame 1. Support blocks 2 are symmetrically fixedly connected to the top of the frame 1. Fixing frames 201 are fixedly connected to the top of the two support blocks 2. Rod holes are symmetrically opened on the top of the fixing frames 201. Guide rods 202 are slidably connected within the rod holes of the fixing frames 201. Mounting plates 203 are fixedly connected to the bottom of the two guide rods 202. Needles 204 are evenly distributed on the bottom of the mounting plates 203. A sliding hole is opened in the middle of the fixing frames 201, and a lifting rod 20 is slidably connected within the sliding hole of the fixing frames 201. 5. The bottom end of the lifting rod 205 is fixedly connected to the top of the mounting plate 203. The top end of the lifting rod 205 is fixedly connected to the rod cap 206. The rod cap 206 and the fixed frame 201 are fixedly connected to the opposite side of the fixed frame 201. The fixed frame 201 is equipped with a motor 208. The output end of the motor 208 is fixedly connected to a cam 209. The two support blocks 2 are symmetrically rotated and connected to the opposite side of the auxiliary roller 210. The fixed frame 201 is equipped with an anti-static component. The top of the frame 1 is sequentially equipped with a cleaning component, a blowing heating component, and a pressure roller component.
[0033] Specifically, when the coated sheet is conveyed into the puncture and exhaust station, motor 208 is started, driving cam 209 to rotate. The outer edge of cam 209 periodically presses the rod cap 206 downward, thereby driving the lifting rod 205 to move down. Spring 207 is compressed. The lifting rod 205 drives the mounting plate 203 and the needles 204 at its bottom to move down synchronously. When the protruding end of cam 209 passes the rod cap 206, the pressing force disappears. The compressed spring 207 rebounds due to elasticity. The rod cap 206, lifting rod 205 and mounting plate 203 move up as a whole. The needles 204 move up synchronously. As cam 209 continues to rotate, needles 204 move up and down repeatedly, thereby puncturing the film coated on the color steel sheet repeatedly, puncturing and expelling the air trapped between the film and the sheet, and solving the defect of internal air accumulation and bulging after coating.
[0034] During the puncture and venting process, two symmetrically arranged auxiliary rollers 210 press down on both sides of the plate, which can balance the local pressure brought by the downward puncture of the needle 204, prevent the plate from bending or shifting due to the downward pressure of the needle 204, and ensure that the puncture operation is carried out smoothly.
[0035] Please see the appendix Figure 2 Appendix Figure 3 Appendix Figure 5 -Appendix Figure 9The antistatic assembly includes a bracket 3, the bottom of which is fixedly connected to the top of a fixed frame 201. A sleeve 301 is fixedly connected to the middle of the bracket 3. A piston block 302 is disposed inside the sleeve 301. A piston rod 303 is fixedly connected to the bottom of the piston block 302. A round cap 304 is fixedly connected to the bottom end of the piston rod 303. A spring 305 is fixedly connected to the side of the round cap 304 opposite to the sleeve 301. An air inlet pipe 306 is fixedly connected to the top of the sleeve 301. A first one-way valve is disposed on the outer wall of the air inlet pipe 306. A gas supply pipe 310 is fixedly connected to one side of the hollow tube 308. The end of the gas supply pipe 310 away from the sleeve 301 is fixedly connected to one side of the hollow tube 308. A second one-way valve is provided at the end of the gas supply pipe 310 near the sleeve 301. Nozzles 309 are evenly fixedly connected to the outer wall of the hollow tube 308. A support plate 307 is fixedly connected to the bottom of the hollow tube 308. The bottom of the support plate 307 is fixedly connected to the top of the shell 5. A guide pipe 311 is fixedly connected to the top of the gas supply pipe 310. A storage cylinder 312 is upside down at the top of the guide pipe 311.
[0036] Specifically, when the heated and dried sheet material arrives at the spraying station, motor 208 is started, driving cam 209 to rotate. During the rotation of cam 209, it periodically presses the round cap 304, pushing the round cap 304 to reciprocate up and down, which in turn causes piston rod 303 to drive piston block 302 to reciprocate up and down within sleeve 301. When piston block 302 moves down, the first one-way valve on air inlet pipe 306 opens, and the second one-way valve on air delivery pipe 310 closes, allowing external gas to enter sleeve 301 through air inlet pipe 306. When piston... When block 302 moves upward, the first one-way valve on the air inlet pipe 306 closes, and the second one-way valve on the air delivery pipe 310 opens. The gas in sleeve 301 is pushed into the air delivery pipe 310, then flows into hollow pipe 308, and finally is sprayed out through nozzle 309. The negative ion antistatic coating stored in storage cylinder 312 is mixed and atomized under the negative pressure of high-pressure airflow. It is evenly sprayed onto the surface of color steel plate from nozzle 309 along with the airflow, completing the antistatic treatment of the plate surface, eliminating the problem of static electricity adsorption of dust on the plate, and improving the antistatic function of color coated plate.
[0037] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 6 Appendix Figure 8The blowing heating assembly includes two housings 5, with their opposite sides fixedly connected to the top and bottom of the frame 1, respectively. A heating plate 505 is provided inside the housing 5, and ventilation holes are evenly distributed inside the heating plate 505. A first air pump 501 is installed on the top of the upper housing 5, and a first air pipe channel 502 is fixedly connected to the output end of the first air pump 501. Branch pipes 503 are symmetrically fixedly connected to one side of the first air pipe channel 502, and the ends of the two branch pipes 503 away from the first air pipe channel 502 are respectively fixedly connected to one side of the housing 5.
[0038] Specifically, after dust removal and cleaning, the sheet material continues to be conveyed forward and enters the blowing and heating station. The first air pump 501 is started, and the gas is diverted through the first air pipe channel 502 to two branch pipes 503, and then flows into two housings 5. With the cooperation of the heating plate 505, the airflow is evenly heated when it passes through the heating plate 505. The high-temperature hot air is blown from the vent to the upper and lower surfaces of the color steel sheet. The hot air preheats the sheet surface in advance, and the overall temperature of the sheet material is increased. The subsequent negative ion antistatic coating is sprayed and the curing speed is accelerated after contacting the sheet surface, shortening the coating drying time and improving the processing efficiency of the entire production line. At the same time, it can provide a dry, clean, and temperature-uniform high-quality substrate surface for the subsequent lamination process, improving the adhesion of the lamination.
[0039] Please see the appendix Figure 1 -Appendix Figure 4The cleaning assembly includes two U-shaped frames 6, the bottoms of which are fixedly connected to the top of the frame 1. Limiting rods 601 are symmetrically fixedly connected inside each of the two U-shaped frames 6. Movable frames 602 are slidably connected to the outer walls of the multiple limiting rods 601. Springs 603 are symmetrically fixedly connected to opposite sides of the U-shaped frames 6 and the movable frames 602. Pressure rollers 604 are symmetrically rotatably connected inside the movable frames 602. An upper cleaning roller 605 is rotatably connected inside the movable frames 602. An upper cavity tube 616 is installed inside the movable frames 602. A lower cleaning roller 611 is rotatably connected inside the frame 1. A lower cavity tube 609 is installed inside the frame 1. Air outlets 610 are evenly fixedly connected to the top of the lower cavity tube 609 and the bottom of the upper cavity tube 616. One side of the frame 1... A support base 606 is fixedly connected to the outer side wall. A second air pump 607 is installed on the top of the support base 606. A second air pipe channel 608 is fixedly connected to the output end of the second air pump 607. One end of the upper cavity pipe 616 and the lower cavity pipe 609 are connected to the second air pipe channel 608. One end of the upper cleaning roller 605 and the two pressure rollers 604 are fixedly connected to toothed pulleys 613. Toothed belts 614 are meshed on the outer walls of the multiple toothed pulleys 613. A motor 612 is installed on one side of the movable frame 602. The output end of the motor 612 is fixedly connected to one end of one of the pressure rollers 604. A protective cover 615 is installed on the other side of the movable frame 602. The toothed pulleys 613 and the toothed belts 614 are both located inside the protective cover 615.
[0040] Specifically, when the sheet material is conveyed into the front-end cleaning station, the second air pump 607 is started. High-pressure gas flows into the upper cavity pipe 616 and the lower cavity pipe 609 through the second air pipe channel 608, and is finally sprayed out through the air outlet 610, which can blow away the floating dust and metal debris on the upper and lower surfaces of the color steel sheet. At the same time, the motor 612 is started to drive one of the pressure rollers 604 to rotate. Under the meshing transmission of the toothed pulley 613 and the toothed belt 614, the two pressure rollers 604 and the upper cleaning roller 605 rotate synchronously. With the cooperation of the lower cleaning roller 611, the upper and lower cleaning rollers roll and wipe the surface of the sheet material to remove stubborn oil stains and dust particles. The movable frame 602 is limited by the sliding limit rod 601. With the cooperation of the spring 603, it can adapt to the thickness of the sheet material to ensure that the cleaning roller 611 is always in close contact with the surface of the sheet material, and complete the pretreatment of the sheet material surface in all directions to avoid defects such as coating particles and insufficient adhesion in the subsequent spraying process.
[0041] By setting up a protective cover 2615, various impurities can be isolated, preventing dust from getting stuck in the meshing grooves of toothed pulley 2613 and toothed belt 2614, preventing belt slippage, skipping teeth, and jamming. At the same time, it can enclose toothed pulley 2613 and toothed belt 2614, preventing human limbs and clothing from touching the meshing rotating parts and eliminating safety hazards.
[0042] Please see the appendix Figure 1 -Appendix Figure 3 Appendix Figure 10 The pressure roller assembly includes two fixed frames 4. The bottom of the two fixed frames 4 are fixedly connected to the top of the frame 1. Lifting blocks 401 are slidably connected inside the two fixed frames 4. Pressing rollers 402 are rotatably connected to the opposite side of the two lifting blocks 401. Uprights 403 are fixedly connected inside the two fixed frames 4. Uprights 403 are set through the lifting blocks 401 and are slidably connected to the lifting blocks 401. Springs 404 are fixedly connected between the top of the lifting blocks 401 and the top inner wall of the fixed frames 4.
[0043] Specifically, after the puncture and degassing process, the coated sheet material is continuously conveyed forward and enters the pressure roller leveling station at the end of the production line. Under the action of spring 404, the pressing roller 402 is made to closely adhere to the surface of the coated sheet material and roll and press synchronously with the sheet material, so as to achieve the rolling and smoothing of the pressing roller 402. The tiny residual air bubbles that were not completely removed in the puncture process will be discharged outward along the puncture micro-holes under the action of roller pressure. The wrinkles generated during the coating process are flattened and eliminated, so that the coating and the negative ion coating are closely adhered to form a flat, smooth, bulging-free, wrinkle-free finished color-coated sheet with a negative ion antistatic coating.
[0044] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 10 Inside the frame 1, conveyor rollers 7 are uniformly rotatably connected. One end of each conveyor roller 7 is fixedly connected to a toothed pulley 701. The outer walls of the toothed pulleys 701 are meshed with toothed belts 702. A motor 703 is installed on one side of the frame 1. The output end of the motor 703 is fixedly connected to one end of one of the conveyor rollers 7. A protective cover 704 is installed on the other side of the frame 1. The toothed pulleys 701 and toothed belts 702 are all located inside the protective cover 704.
[0045] Specifically, when conveying the color steel plate, the color steel plate substrate to be processed is placed on the conveyor roller 7, the motor 703 is started, and one of the conveyor rollers 7 is driven to rotate. Under the meshing transmission of the toothed pulley 701 and the toothed belt 702, multiple conveyor rollers 7 rotate synchronously, so that the color steel plate can be stably and automatically conveyed forward along the assembly line.
[0046] By setting up a protective cover 704, various impurities can be isolated, preventing dust from getting stuck in the meshing grooves of the toothed pulley 701 and the toothed belt 702, preventing belt slippage, skipping teeth, and jamming, ensuring that all conveying rollers 7 rotate synchronously and at a uniform speed, and the plate conveying speed is stable. At the same time, it can also wrap the toothed pulley 701 and the toothed belt 702 inside, preventing human limbs and clothing from touching the meshing rotating parts, and eliminating safety hazards.
[0047] Please see the appendix Figure 1 -Appendix Figure 3 Appendix Figure 5 -Appendix Figure 6 The top of the upper shell 5 is symmetrically fixed with a card holder 8, and a film-coated roll 801 is provided in the U-shaped groove at the top of the two card holders 8.
[0048] Specifically, a U-shaped groove is provided at the top of the card holder 8, which can be directly used to mount the film roll 801, making it easy for operators to quickly replace and load / unload the protective film roll.
[0049] Work process: Place the color steel plate substrate to be processed on the conveyor roller 7, start the motor 3 703 to drive one of the conveyor rollers 7 to rotate, and under the meshing transmission of toothed pulley 1 701 and toothed belt 1 702, make multiple conveyor rollers 7 rotate synchronously, and automatically and stably convey the color steel plate forward along the production line direction.
[0050] The sheet material is first conveyed into the front-end cleaning station. The second air pump 607 is started, and high-pressure gas flows into the upper cavity pipe 616 and the lower cavity pipe 609 through the second air pipe channel 608, and is finally sprayed out through the air outlet 610 to blow away the floating dust and metal debris on the upper and lower surfaces of the color steel sheet. At the same time, the motor 612 is started to drive one of the pressure rollers 604 to rotate. Under the meshing transmission of the toothed pulley 613 and the toothed belt 614, the two pressure rollers 604 and the upper cleaning roller 605 rotate synchronously. With the cooperation of the lower cleaning roller 611, the upper and lower cleaning rollers roll and wipe the surface of the sheet material to remove stubborn oil stains and dust particles. The movable frame 602 is limited by the sliding limit rod 601. With the cooperation of the spring 603, it adapts to the thickness of the sheet material to ensure that the cleaning roller 611 is always in close contact with the surface of the sheet material, and completes the pretreatment of the sheet material surface in all directions.
[0051] After dust removal and cleaning, the sheet material continues to be conveyed forward and enters the blowing and heating station. The first air pump 501 is started, and the gas is diverted through the first air pipe channel 502 to two branch pipes 503, and then flows into two housings 5. With the cooperation of the heating plate 505, the airflow is evenly heated when it passes through the heating plate 505. The high-temperature hot air is blown from the vent to the upper and lower surfaces of the color steel sheet. The hot air preheats the sheet surface in advance, and the overall temperature of the sheet material is raised. The subsequent negative ion antistatic coating is sprayed and the curing speed is accelerated after contacting the sheet surface, shortening the coating drying time. At the same time, it provides a dry, clean, and temperature-uniform high-quality substrate surface for the subsequent lamination process.
[0052] After the heated and dried sheet material arrives at the spraying station, motor 208 is started, driving cam 209 to rotate. During the rotation of cam 209, it periodically presses the round cap 304, pushing the round cap 304 to reciprocate up and down. This, in turn, causes piston rod 303 to drive piston block 302 to reciprocate up and down within sleeve 301. When piston block 302 moves down, the first one-way valve on the air inlet pipe 306 opens, and the second one-way valve on the air delivery pipe 310 closes, allowing outside gas to enter the sleeve through the air inlet pipe 306. Inside the cylinder 301, when the piston block 302 moves upward, the first one-way valve on the air inlet pipe 306 closes and the second one-way valve on the air delivery pipe 310 opens. The gas inside the sleeve 301 is pushed into the air delivery pipe 310, then flows into the hollow pipe 308, and finally is sprayed out through the nozzle 309. The negative ion antistatic coating stored in the storage cylinder 312 is mixed and atomized under the negative pressure of the high-pressure airflow. It is then evenly sprayed onto the surface of the color steel plate from the nozzle 309 along with the airflow, completing the antistatic treatment of the plate surface.
[0053] A film-coated roll 801 is placed at the top of the card holder 8, and the protective film is attached to the surface of the board coated with negative ion coating;
[0054] After the film is coated, the sheet material is conveyed into the piercing and venting station. When the cam 209 rotates, the outer edge of the cam 209 periodically presses the rod cap 206 downward, which in turn drives the lifting rod 205 to move down. The spring 207 is compressed. The lifting rod 205 drives the mounting plate 203 and the needle 204 at its bottom to move down synchronously. When the cam 209 passes the rod cap 206, the pressing force disappears. The compressed spring 207 rebounds due to its elasticity. The rod cap 206, the lifting rod 205 and the mounting plate 203 move up as a whole. The needle 204 moves up synchronously. As the cam 209 continues to rotate, the needle 204 moves up and down back and forth, completing the reciprocating piercing operation of the film coated on the color steel sheet, piercing and expelling the air trapped between the film and the sheet material.
[0055] After the board material has been punctured and degassed, it enters the final pressure roller leveling station. Under the action of spring 404, the pressing roller 402 is pressed tightly against the surface of the coated board material. It rolls and presses synchronously with the board material conveying, so as to achieve the rolling and smoothing of the pressing roller 402. The tiny residual air bubbles that were not completely removed in the puncture process will be discharged outward along the puncture micro-holes under the action of roller pressure. The wrinkles generated in the coating process are flattened and eliminated, so that the coating and the negative ion coating are tightly bonded, forming a flat, smooth, bulging-free, wrinkle-free finished color-coated board with a negative ion antistatic coating.
[0056] The finished sheet is automatically fed out from the rear of the equipment under the continuous drive of the conveyor roller 7. The entire production line runs continuously from sheet feeding, dust removal, heating and drying, negative ion antistatic spraying to remove static electricity, film coating, puncture and exhaust, pressure roller leveling to finished product discharge, completing the whole set of automated production. No manual intervention is required throughout the process, realizing continuous production line processing.
[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
