Description

Technical Field

[0001] This invention belongs to the field of color-coated steel sheet production technology, and in particular relates to a production device and color-coated steel sheet of high corrosion-resistant water-based material. Background Technology

[0002] Color-coated steel sheets are composite materials made by coating organic paint onto a metal substrate and then baking and curing them. They possess excellent corrosion resistance, weather resistance, and decorative properties. They are widely used in construction, home appliances, automobiles, and other fields, offering a variety of colors and patterns, as well as good processing performance. The production process of color-coated steel sheets is as follows: uncoiling, sewing, inlet looper, cleaning, chemical treatment, initial coating, initial coating baking, initial coating cooling, fine coating, fine coating baking, fine coating cooling, outlet looper, quality inspection, printing, slitting, and winding. The sewing process involves welding the ends of the front and rear substrates together to achieve continuous production.

[0003] During the stitching process, improper storage and management of the substrate can lead to oil stains on the edges, or bumps during transport can cause uneven edges. Whether it is oil stains or unevenness at the welding ends, it will affect the welding strength at the stitching point, which may lead to welding defects. This requires production to be interrupted for adjustment and repair, reducing production efficiency. In addition, in some areas, the low winter temperature and the low temperature of the cleaning solution slow down the chemical reaction rate, reduce the cleaning ability, and result in poor cleaning effect on the substrate, affecting the subsequent spraying quality and leading to an increase in the defect rate. Summary of the Invention

[0004] The purpose of this invention is to provide a production device and a color-coated sheet for high corrosion-resistant water-based materials, which allows for convenient replacement of cleaning rollers.

[0005] The high corrosion-resistant water-based material color-coated plate production apparatus includes an uncoiler for conveying substrates to the right, and a first cleaning device is provided to the right of the uncoiler.

[0006] The first cleaning device includes a cleaning device housing. The cleaning device housing has a first feed port that allows the substrate to pass horizontally and is open to the left and right. The cleaning device housing has a cleaning roller that is longitudinally arranged to clean the substrate and can rotate left and right. The front and rear ends of the cleaning roller are detachably and rotatably connected to a mounting frame. The front and rear ends of the mounting frame are rotatably connected to the cleaning device housing. After the mounting frame is rotated, the cleaning roller is located above the cleaning device housing. The cleaning device housing has several nozzles for spraying cleaning liquid.

[0007] A light curtain sensor is installed to the right of the first cleaning device, a first cutting machine is installed to the right of the light curtain sensor, a sewing machine is installed to the right of the first cutting machine, a second cleaning device is installed to the right of the sewing machine, and a first dryer is installed at the output end of the second cleaning device.

[0008] The first dryer includes a dryer shell, and a hot water component is installed inside the dryer shell. The liquid outlet of the hot water component is connected to the liquid inlet of the nozzle and the liquid inlet of the second cleaning device through water supply pipes.

[0009] The substrate on the uncoiler first enters the first cleaning equipment, where it is cleaned and dried. The substrate passes through the first feed port to the right, and cleaning fluid is sprayed onto the substrate and cleaning rollers. The cleaning rollers then scrub the substrate. Afterward, the substrate is inspected by a light curtain sensor to check for unevenness and damage. Unevenness at the welding end can affect the weld strength, leading to weld defects. If the light curtain sensor detects unevenness at the end of the substrate to be welded, the uneven section is cut off when that end enters the first cutting machine. Then, welding is performed inside the sewing machine. The hot water component uses the heat inside the dryer casing to heat the cleaning fluid sprayed from the nozzles, and also heats the cleaning fluid required in the second cleaning device. Even when the ambient temperature is low, the cleaning fluid can still be kept at the temperature for optimal cleaning effect. When the cleaning roller needs to be replaced, rotate the mounting bracket to position the cleaning roller above the cleaning device casing, remove the cleaning roller from the mounting bracket for replacement, and after replacement, rotate the mounting bracket to position the cleaning roller inside the cleaning device casing to clean the substrate. This solution mainly has the following four major effects: First, in the sewing machine... First, the substrate is cleaned before welding, which not only reduces the impact of oil and other contaminants on welding quality but also improves the cleaning efficiency of the second cleaning equipment. Second, the light curtain sensor can detect whether the end of the substrate to be welded is flat. If it is uneven, the first cutting machine cuts off the uneven section before the substrate enters the sewing machine for welding, further improving welding quality and eliminating the need to stop production for adjustments due to welding defects, thus increasing production efficiency. The light curtain sensor can also continuously monitor whether the substrate is damaged. If damaged, the damaged section is cut off by the first cutting machine before welding by the sewing machine, reducing the substrate defect rate and improving the production quality of color-coated sheets. Third, the first dryer used to dry the substrate after cleaning heats the cleaning liquid used on the production line. Even when the ambient temperature is low, the cleaning liquid can be kept at the temperature for optimal cleaning effect, thereby improving the pass rate of subsequent processes such as spraying. Fourth, by rotating the mounting frame, the cleaning roller can be rotated to the top of the cleaning equipment housing. The cleaning roller can be easily replaced without reaching into the cleaning equipment housing or opening the cleaning equipment housing. The cleaning equipment housing can also prevent the cleaning liquid sprayed from the nozzle from splashing everywhere.

[0010] Furthermore, two longitudinal fixing columns are symmetrically installed at vertical intervals on the mounting frame. The center line of the rotatable connection between the mounting frame and the outer shell of the cleaning equipment coincides with the axis of symmetry between the upper and lower fixing columns. The inner ends of the fixing columns are all fixed with longitudinal studs. The end of the cleaning roller is machined with a threaded hole that is threaded to the stud. The lower stud is threaded to the end of the cleaning roller. The outer ends of the fixing columns pass through the mounting frame independently. A disassembly and assembly assembly is installed on the outer shell of the cleaning equipment corresponding to the upper fixing column to drive the rotation of the fixing column. When the disassembly and assembly assembly drives the fixing column to rotate, it drives the stud to move back and forth.

[0011] The stud is screwed into the threaded hole at the end of the cleaning roller, connecting the roller to the thread. When the cleaning roller needs to be replaced, rotate the mounting bracket, and the cleaning roller will rotate to the top of the cleaning equipment housing. The upper and lower fixing posts on both sides will then be swapped. After the mounting bracket rotates, the fixing post corresponding to the cleaning roller will be on the upper side, securing the cleaning roller. The disassembly and assembly assembly drives the fixing post corresponding to the cleaning roller to rotate, causing the stud to move outward and separate from the cleaning roller. After removing the cleaning roller and inserting the new cleaning roller, the disassembly and assembly assembly drives the fixing post to rotate, simultaneously causing the stud to move inward and screw into the threaded hole at the end of the cleaning roller. Rotate the mounting bracket to rotate the cleaning roller to the lower working position. This allows for convenient loading and unloading of the cleaning rollers. To speed up the replacement process, a cleaning roller can also be installed between the two fixed posts on the upper side. When replacing the roller, simply rotate the mounting frame to put the new cleaning roller into use, further saving replacement time. In actual use, a cleaning roller can also be installed inside the cleaning equipment housing below the first feed inlet to achieve double-sided cleaning of the substrate. When there are two cleaning rollers, there are four fixed posts at one end of the two cleaning rollers. Two of these posts are used to connect the cleaning rollers, and the other two are located above the rotating connection between the mounting frame and the cleaning equipment housing, and are symmetrically distributed with the fixed posts on the lower side.

[0012] Furthermore, the disassembly and assembly assembly includes a cylinder that can extend and retract back and forth, a disassembly and assembly motor is fixed on the piston rod of the cylinder, and disassembly and assembly holes that cooperate with the drive shaft of the disassembly and assembly motor are opened on the outer ends of the fixing columns.

[0013] When the cleaning roller needs to be disassembled, the cylinder drives the rotating shaft of the disassembly / assembly motor to extend into the disassembly / assembly hole. The drive shaft of the disassembly / assembly motor rotates, causing the stud to exit the threaded hole at the end of the cleaning roller. At the same time, the cylinder drives the disassembly / assembly motor to move outward, thus removing the cleaning roller. When installing the cleaning roller, the drive shaft of the disassembly / assembly motor rotates, causing the stud to extend into the threaded hole at the end of the fixing post. At the same time, the cylinder drives the disassembly / assembly motor to move inward, completing the quick installation and disassembly of the cleaning roller. After the cleaning roller is installed, the mounting bracket is rotated, causing the cleaning roller to rotate to the working position. The cylinder then drives the disassembly / assembly motor to move inward, and the drive shaft of the disassembly / assembly motor moves inward against the disassembly / assembly hole, limiting the mounting bracket and preventing rotation. The disassembly / assembly assembly not only enables convenient installation and removal of the cleaning roller but also limits the mounting bracket, making the operation convenient.

[0014] Furthermore, gears are fixed to the outer ends of the fixed columns located on the front side, and transmission gears that mesh with the gears are provided on the upper side of the gears. The transmission gears are connected to a drive motor that drives them to rotate.

[0015] The transmission gear is mounted on the drive shaft of the drive motor. The drive motor drives the transmission gear to rotate, which in turn drives the gear to rotate, thereby driving the fixed column to rotate and realize the rotation of the cleaning roller to clean the substrate. At the same time, the transmission gear located on the upper side does not affect the rotation of the gear with the mounting bracket. When replacing the cleaning roller, only the drive motor needs to be stopped, and the mounting bracket can be rotated to drive the gear to rotate, which further increases the convenience of cleaning roller replacement.

[0016] Furthermore, each mounting bracket at the rotatable connection point with the outer casing of the cleaning equipment is fixed with a longitudinal cylindrical platform. The inner end of the cylindrical platform is fixed to the mounting bracket, and the outer end is rotatably connected to the outer casing of the cleaning equipment. After passing through the mounting bracket, a limiting cylinder is connected, and a rotating component is installed on the limiting cylinder.

[0017] The limiting cylinder has an internal thread, and the outer end of the cylindrical platform has an external thread that is threaded to the internal thread, so that the limiting cylinder is threadedly fitted onto the cylindrical platform. The rotating part can be a bolt, which can not only further tighten the limiting cylinder and the cylindrical platform, but also be used as a handle to facilitate the rotation of the mounting bracket.

[0018] Furthermore, a collection frame for temporarily placing the cleaning roller is detachably connected between the front and rear mounting brackets.

[0019] When replacing the cleaning roller, rotate the mounting bracket so that the cleaning roller is located above the outer shell of the cleaning equipment. Install the collection frame below the cleaning roller. If the cleaning roller is heavy, move the stud outward so that the cleaning roller can fall directly into the collection frame and then be moved away, which is more convenient.

[0020] Furthermore, an air knife for drying the substrate is installed on the right end of the cleaning equipment housing. The air inlet of the air knife is connected to an air pump through an air supply pipe. The air outlet of the air pump is connected to the air inlet of the air supply pipe. The air inlet of the air pump is connected to the dryer housing through a pipe.

[0021] The air pump delivers heated gas from inside the dryer casing to the air knife, accelerating the cleaning of residual liquid on the substrate.

[0022] Furthermore, the first cutting machine includes two fixed seats that are spaced apart from each other and symmetrically arranged. The substrate passes through the upper side of the fixed seats. Each fixed seat has a pressure block that can move up and down above it. After the pressure block moves down, it presses the substrate onto the fixed seat. A cutting blade that can move up and down is installed between the two fixed seats.

[0023] After the pressure block moves down, it presses the substrate onto the fixed base. The cutting blade moves downward to cut the substrate, removing the first and last sections of the substrate to improve the quality of the first and last welding.

[0024] Furthermore, the collection frame is fixed to the mounting bracket by fixing bolts, and the cylinder body is mounted on the outer shell of the cleaning equipment by the fixing bracket;

[0025] The bottom of the pressure block is connected to a first hydraulic rod that can extend and retract vertically, and the bottom of the cutting blade is connected to a second hydraulic rod that can extend and retract vertically. A debris collection box is set below the cutting blade. The dryer shell has a second feed port for the substrate to pass through and is open to the left and right. The outlet end of the second feed port is sequentially equipped with a coating machine, a second dryer, a second cutting machine and a winding machine. After the substrate passes through the dryer shell, it enters the coating machine for coating, and then enters the second dryer for drying to obtain a color-coated plate. The color-coated plate is slit by the second cutting machine, and the winding machine rolls up the slit color-coated plate.

[0026] An auxiliary feeding mechanism for assisting substrate conveying is provided between the uncoiler and the first cleaning equipment, between the first cutting machine and the sewing machine, between the second cleaning equipment and the first dryer, and between the second cutting machine and the rewinder.

[0027] The first hydraulic rod drives the pressure block to move up and down, and the second hydraulic rod drives the cutting blade to move up and down, which is convenient for control. The debris collection box can easily receive the debris that falls off during cutting. The fixing bolts make it easy to disassemble and assemble the collection frame. The coating machine and the second dryer can be set to multi-stage coating and drying as needed. The number of auxiliary feeding mechanisms can be increased or decreased during actual use.

[0028] A color-coated steel sheet, prepared according to the aforementioned high corrosion-resistant water-based material color-coated steel sheet production apparatus.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] First, cleaning the substrate before welding with the sewing machine not only reduces the impact of oil and other contaminants on welding quality, but also improves the cleaning efficiency of the second cleaning equipment.

[0031] Secondly, the light curtain sensor can not only detect whether the end of the substrate to be welded is flat, but also cut off the uneven section of the substrate by the first cutting machine when it is uneven, and then enter the sewing machine for welding, which further improves the welding quality and eliminates the need to stop production for adjustment due to welding defects, thus improving production efficiency; the light curtain sensor can also continuously monitor whether the substrate is damaged. If there is damage, the damaged section is cut off by the first cutting machine and then welded by the sewing machine, which reduces the defect rate of the substrate and improves the production quality of the color coated plate.

[0032] Third, the cleaning solution used on the production line is heated by the first dryer after the substrate is cleaned and dried. Even when the ambient temperature is low, the cleaning solution can still be kept at the temperature at which the cleaning effect is optimal, thereby improving the pass rate of subsequent processes such as spraying.

[0033] Fourth, by rotating the mounting bracket, the cleaning roller can be rotated to the top of the cleaning equipment housing. The cleaning roller can be easily replaced without having to reach into the cleaning equipment housing or open the cleaning equipment housing. The cleaning equipment housing can prevent the cleaning liquid sprayed from the nozzle from splashing everywhere. Attached Figure Description

[0045] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0046] Example

[0047] The high corrosion-resistant water-based material color-coated sheet production device and color-coated sheet described in this embodiment are implemented using the following scheme:

[0048] The high corrosion-resistant water-based color-coated steel sheet produced using the high corrosion-resistant water-based color-coated steel sheet production equipment is made by coating a substrate with a high corrosion-resistant water-based coating. The high corrosion-resistant water-based coating has the following raw material composition by mass percentage: 35% graphene oxide modified water-based epoxy resin, 10% acrylic emulsion, 8% nano silica sol, 30% water-based color paste, 0.5% wetting agent, 0.5% leveling agent, and 16% water.

[0049] like Figure 1As shown, prepare an uncoiler 1 and place the uncoiler horizontally.

[0050] Uncoiling is a known technology. Uncoiling mainly unwinds rolled materials by rotating a drum and uses a tension control system to maintain constant tension, guiding the substrate 13 to be transported smoothly.

[0051] like Figure 1 As shown, a first cleaning device 2 is provided to the right of the uncoiler 1.

[0052] The first cleaning device 2 includes a cleaning device housing 2.1 made of metal materials such as cast steel, and as follows: Figure 3 As shown, a first feed port 2.13 that is open from left to right is machined on the outer shell 2.1 of the cleaning equipment. Several longitudinal support rollers are installed at left and right intervals at the bottom of the first feed port 2.13. Several nozzles 2.14 are installed inside the outer shell 2.1 of the cleaning equipment for spraying cleaning liquid. The liquid inlet end of the nozzle 2.14 is connected to a water supply pipe 2.6.

[0053] like Figure 2 As shown, an air knife 2.7 is fixed to the right end of the outer shell 2.1 of the cleaning equipment. An air supply pipe 2.8 is connected to the air inlet end of the air knife 2.7, and an air pump 2.11 is connected to the air supply pipe 2.8.

[0054] A mounting bracket 2.5 is fixed to the front top of the cleaning equipment housing 2.1, and a disassembly / assembly assembly 2.9 is fixed on the mounting bracket 2.5. The disassembly / assembly assembly 2.9 consists of a cylinder 2.9.1 and a disassembly / assembly motor 2.9.2, with the motor mounted on the piston rod of the cylinder 2.9.1. Both the cylinder 2.9.1 and the motor 2.9.2 are existing technologies. The cylinder 2.9.1 uses compressed air to drive the piston to reciprocate within the cylinder, thus retracting the piston rod. When the disassembly / assembly motor 2.9.2 is energized, the motor coil generates a magnetic field, which interacts with the stator's magnetic field to rotate the rotor, thereby driving the transmission shaft to rotate.

[0055] The cleaning equipment housing 2.1 contains a cleaning roller 2.15 for wiping and a mounting bracket 2.4 for mounting the cleaning roller 2.15; mounting brackets 2.4 are installed on both the front and rear side walls inside the cleaning equipment housing 2.1, such as... Figure 4 As shown, the main structure of the mounting bracket 2.4 is a square plate. The mounting bracket 2.4 has through holes that are open from front to back near the top and bottom ends. Fixing posts 2.16 are installed in the through holes and are rotatably fitted with the mounting bracket 2.4.

[0056] A cylindrical platform 2.22 is fixed at the center of the outer side of the two mounting brackets 2.4 facing the outer side of the cleaning equipment housing 2.1. A threaded hole is machined at the center of the inner side of the mounting bracket 2.4, and a threaded fixing bolt 2.17 is installed in the threaded hole. The cylindrical platform 2.22 passes through the outer side of the cleaning equipment housing 2.1 and is rotatably connected to the mounting bracket 2.4.

[0057] Prepare a limiting cylinder 2.3. A threaded hole is machined on the outer wall of the limiting cylinder 2.3. A bolt that is threadedly engaged with the bolt is installed in the threaded hole as a rotating part 2.10. The limiting cylinder 2.3 has an internal thread. An external thread is machined on the cylindrical platform located outside the outer shell 2.1 of the cleaning equipment, which is threadedly engaged with the internal thread of the limiting cylinder 2.3.

[0058] Prepare a cleaning roller 2.15. The main structure of the cleaning roller 2.15 is a metal shaft, on which a cleaning sponge is fixed. Threaded holes are machined at both ends of the cleaning roller 2.15. Figure 4 As shown, both the front and rear ends of the cleaning roller 2.15 are connected to the fixing post 2.16. The end of the fixing post 2.16 facing the cleaning roller 2.15 passes inward through the mounting bracket 2.4 and is fixed with a stud 2.19. The stud 2.19 is threadedly connected to the threaded hole at the end of the cleaning roller 2.15. The other end of the fixing post 2.16 is fixed with a gear 2.20, and a regular hexagonal hole is machined at the center. This hole is the disassembly hole 2.21.

[0059] like Figure 4 As shown, a metal box is prepared as a collection frame 2.18. The front and rear ends of the collection frame 2.18 are fixed to the mounting frame 2.4 by fixing bolts 2.17. It is used to temporarily place the cleaning roller 2.15 when replacing the cleaning roller 2.15.

[0060] In assembly 2.9, the shaft of the motor 2.9.2 corresponds to the hexagonal assembly / disassembly hole 2.21 on the fixed post 2.16.

[0061] like Figure 3 As shown, a drive motor 2.2 is fixed to the left side of the cleaning equipment housing 2.1, and a transmission gear 2.12 is fixed to the drive shaft of the drive motor 2.2. Figure 3 As shown, the transmission gear 2.12 meshes with the gear on the fixed column 2.16.

[0062] like Figure 1As shown, a light curtain sensor 3 is installed on the right side of the first cleaning device 2. The light curtain sensor 3 is used to detect whether the front and rear ends of the substrate 13 are flat. Once light is blocked, the control unit is triggered and outputs a signal that the substrate 13 is not flat. It is also used to detect whether the substrate 13 transported from the left side is damaged or uneven. Specifically, the light curtain sensor 3 is installed in two sets of light curtains on the front and rear sides and the top and bottom sides of the substrate 13. The set of light curtains on the front and rear sides is used to detect whether the substrate 13 is flat. If it is not flat, the light emitted by the transmitting light curtain will be blocked, and the receiving light curtain will not receive the light emitted by the transmitting light curtain, outputting a blocked signal, indicating that the substrate 13 is not flat. The set of light curtains on the top and bottom sides is used to detect whether the substrate 13 is damaged. If it is damaged, the light emitted by the transmitting light curtain will pass through the damaged point, and the receiving light curtain will receive the light emitted by the transmitting light curtain, outputting a damaged signal, indicating that the substrate 13 is damaged.

[0063] like Figure 1 As shown, a first cutting machine 4 is installed on the right side of the light curtain sensor 3.

[0064] like Figure 5 As shown, the structure of the first cutting machine 4 is symmetrical from left to right. The first cutting machine 4 includes a fixed base 4.3, and a hydraulic cylinder is installed inside the fixed base 4.3. The push rod of the hydraulic cylinder for extension and retraction is called the first hydraulic rod 4.2, and a pressure block 4.1 is fixed to the top of the first hydraulic rod 4.2. Figure 4 As shown, a cutting blade 4.5 is installed in the middle of the first cutting machine 4. Figure 6 As shown, metal shells are installed at both ends of the cutting blade 4.5, and hydraulic cylinders are installed inside the metal shells. The push rod for extending and retracting the hydraulic cylinder is the second hydraulic rod 4.6. A debris collection box 4.4 for collecting cutting debris is provided directly below the cutting blade 4.5.

[0065] like Figure 1 As shown, a sewing machine 5 is installed on the right side of the first cutting machine 4, and a second cleaning device 6 is installed on the right side of the sewing machine 5.

[0066] The second cleaning device 6 is a known existing technology, comprising an acid pickling zone and a cleaning zone. The acid pickling zone is used to degrease the substrate; this step aims to remove grease and dirt from the substrate surface to ensure the quality of subsequent processing. The cleaning zone removes residual chemicals and impurities through alkaline washing and water rinsing, preparing for subsequent chemical conversion treatment. Figure 1 As shown, a first dryer 7 is installed above the second cleaning device 6.

[0067] The first dryer 7 is an existing technology, mainly composed of a dryer shell 7.1, a combustion furnace, a flue, a blower, a motor, a base, and a flue gas exhaust port. For example... Figure 7 As shown, a second feed inlet 7.3 is opened on the outer shell 7.1 of the dryer, extending through both the left and right sides; as Figure 4 As shown, a hot water assembly 7.2 is installed inside the dryer casing 7.1. The hot water assembly 7.2 consists of four hollow columns and multiple hollow round tubes connected together. The specific assembly method of the hot water assembly 7.2 is as follows. Figure 8 and Figure 9 As shown, the hollow columns on the front and rear sides are connected by three hollow round tubes arranged side by side and vertically spaced, and the columns on the left and right sides are connected by horizontal hollow round tubes. A water inlet pipe and a water outlet pipe are connected to one side of each column. The inlet end of the water inlet pipe is connected to the cleaning liquid pipe, and the outlet end of the water outlet pipe is connected to the water supply pipe 2.6. In actual use, the number of hot water components 7.2 is set according to the number of the first cleaning device 2 and the second cleaning device 6. The structure can also be other bypass methods.

[0068] A coating machine 8 is installed on the left side of the first dryer 7. The coating machine 8 is a known technology and typically applies coatings evenly to the surface of the substrate using methods such as roller coating, curtain coating, or powder coating. A second dryer 9 is installed on the left side of the coating machine 8. The structure and principle of the second dryer 9 are the same as those of the first dryer 7. The outlets of the hot water components 7.2 in the first dryer 7 and the second dryer 9 are connected to the water supply pipe 2.6 of the first cleaning device 2 and the inlet of the second cleaning device 6 via pipes, respectively.

[0069] like Figure 1 As shown, a second cutting machine 10 is installed on the left side of the second dryer 9. The second cutting machine 10 is a roll material slitting machine, which is a known technology. It is mainly composed of a box, mounting plate, slide bar, motor plate, drive motor and cutting disc. The device moves the motor plate through the telescopic rod, and the cutting disc connected to the output shaft of the drive motor cuts the color-coated sheet.

[0070] A winding machine 12 is installed on the left side of the second cutting machine 10. The winding machine 12 is located above the unwinding machine 1. Both the unwinding machine 1 and the winding machine 12 are existing known technologies. The principle is that the rolled material is placed on the expansion and contraction drum, and after being tensioned by the expansion and contraction drum, the expansion and contraction drum is driven by the motor to rotate, thereby driving the drum to unwind.

[0071] like Figure 10 As shown, the first dryer 7, the coating machine 8, the second dryer 9, the second cutter 10, and the winding machine 12 are all mounted above the uncoiler 1, the first cleaning device 2, the light curtain sensor 3, the first cutter 4, the sewing machine 5, and the second cleaning device 6 via a U-shaped frame, and as... Figure 1 As shown, auxiliary feeding mechanisms 11 are installed between the uncoiler 1 and the first cleaning device 2, between the first cutter 4 and the sewing machine 5, between the sewing machine 5 and the second cleaning device 6, and between the second cleaning device 6 and the first dryer 7. These mechanisms mainly consist of mounting brackets and rollers and guide the substrate 13.

[0072] The specific instructions for using the above technical solution are as follows:

[0073] The working principle is as follows:

[0074] like Figure 1 As shown, the substrate 13 unwound by the uncoiler 1 is first guided by the auxiliary feeding mechanism 11 into the first feed port 2.13 of the first cleaning equipment 2. After the substrate 13 enters the first cleaning equipment 2, cleaning fluid is supplied from the water pipe 2.6, and then the cleaning fluid is sprayed by the nozzle 2.14. Next, the cleaning roller 2.15 performs preliminary cleaning on the substrate 13 to wipe away dust, grease and other impurities. Then, the air knife 2.7 dries the substrate 13 to prevent impurities on the substrate 13 from affecting the sewing and subsequent work.

[0075] During the cleaning process, such as Figure 4 As shown, the piston rod of cylinder 2.9.1 extends out, and the drive shaft of the mounting motor 2.9.2 extends into the mounting hole 2.21 on the upper fixed post 2.16, thereby restricting the rotation of the mounting bracket 2.4.

[0076] like Figure 1 As shown, when substrate 13 passes through light curtain sensor 3, light curtain sensor 3 detects the flatness of the upper and lower surfaces of substrate 13. If obvious gaps or damage are found, the first cutting machine 4 will then cut substrate 13 to maintain the flatness of the end face. During cutting, as... Figure 5 As shown, the first hydraulic rod 4.2 drives the pressure block 4.1 to press down and fix the base plate 13, and then... Figure 6 As shown, the second hydraulic rod 4.6 drives the cutting blade 4.5 to move down to cut the substrate 13. When the light curtain sensor 3 detects that the end of the previous roll of substrate 13 is uneven, the first cutting machine 4 performs the same process.

[0077] After being cut, substrate 13 is sewn together in sewing machine 5 by welding, and then enters the second cleaning equipment 6 for cleaning. After cleaning, substrate 13 enters the first dryer 7, then enters the coating machine 8 for coating, and then enters the second dryer 9 for drying again. After the second drying is completed, it is slit by the second cutting machine 10, and then wound up by the winding machine 12.

[0078] According to production needs, a coating machine 8 and a second dryer 9 can be installed between the second dryer 9 and the second cutter 10 to perform multiple coating processes until the product requirements are met. Then, the second cutter 10 is used to slit the rolls, and the rewinder 12 is used to rewind them.

[0079] The process of replacing the cleaning roller 2.15 in the first cleaning device 2 is as follows:

[0080] After a period of operation, the cleaning roller 2.15's cleaning ability decreases, requiring periodic replacement. The piston rod of cylinder 2.9.1 retracts, then the mounting bracket 2.4 rotates, positioning the cleaning roller 2.15 to be replaced outside the cleaning equipment housing 2.1. The piston rod of cylinder 2.9.1 then extends again, causing the drive shaft of the disassembly / removal motor 2.9.2 to enter the disassembly / removal hole 2.21 of the fixing post 2.16. The motor operates, and the shaft unscrews the fixing post 2.16 outwards. As the fixing post 2.16 moves, the piston rod of the cylinder slowly moves the motor outwards until the cleaning roller 2.15 can be removed. After replacing the cleaning roller 2.15, the disassembly / removal assembly 2.9 tightens the fixing post 2.16 inwards to secure the cleaning roller 2.15.

[0081] Specifically, when it is necessary to replace the cleaning roller 2.15, rotate the mounting bracket 2.4, and the cleaning roller 2.15 will rotate to the top of the cleaning equipment housing 2.1. The two fixing posts 2.16 will then swap their vertical positions. After the mounting bracket 2.4 rotates, the fixing post 2.16 corresponding to the cleaning roller 2.15 will be on the upper side, fixing the cleaning roller 2.15. The disassembly and assembly component 2.9 will drive the fixing post 2.16 corresponding to the cleaning roller 2.15 to rotate, causing the stud 2.19 to move outward and separate from the cleaning roller 2.15. Remove the cleaning roller 2.15. After the new cleaning roller 2.15 is placed in, the disassembly and assembly component 2.9 will drive the fixing post 2.16 to rotate, simultaneously causing the stud 2.19 to move inward and screw into the threaded hole at the end of the cleaning roller 2.15. Rotate the mounting bracket 2.4 to rotate the cleaning roller 2.15 to the lower side. The working position of the cleaning roller 2.15 is adjusted to facilitate easy loading and unloading. To speed up the replacement, a cleaning roller 2.15 can also be installed between the two upper fixing posts 2.16. When replacing, the new cleaning roller 2.15 can be put into use simply by rotating the mounting frame 2.4, further saving the replacement time of the cleaning roller 2.15. In actual use, the cleaning roller 2.15 can also be installed inside the cleaning equipment housing 2.1 below the first feed port 2.13 to achieve double-sided cleaning of the substrate 13. When there are two cleaning rollers 2.15, there are four fixing posts 2.16. Two of them are used to connect the cleaning rollers 2.15, and the other two are located above the rotatable connection between the mounting frame 2.4 and the cleaning equipment housing 2.1, and are symmetrically distributed downwards with the lower fixing posts 2.16.

[0082] The hot water assembly 7.2 can preheat the cleaning fluid supplied by the inlet pipe using the heat from the first dryer 7, and then deliver it to each nozzle 2.14 through the outlet pipe and water supply pipe 2.6, thereby improving its cleaning effect. Cleaning and end-face cutting are performed before the substrate 13 is sewn, resulting in a good sewing effect. Production can continue even when the cleaning roller 2.15 is being replaced, reducing downtime and improving production efficiency.
