Description

Technical Field

[0001] The invention belongs to the technical field of color-coated plate production, and in particular relates to a production device for color-coated plates made of highly corrosion-resistant water-based materials and the color-coated plates. Background Art

[0002] Color-coated sheet is a composite material coated with organic coating on a metal substrate and cured by baking. It has excellent corrosion resistance, weather resistance and decorative properties. It is widely used in construction, home appliances, automobiles and other fields, providing a variety of colors and patterns to choose from, as well as good processing performance. The production process of color-coated sheet is: unwinding, stitching, inlet looping, cleaning, chemical treatment, initial coating, initial coating baking, initial coating cooling, fine coating, fine coating baking, fine coating cooling, outlet looping, quality inspection, printing, roll division and winding. The stitching process is to weld the front and rear substrates together head and tail to achieve continuous production.

[0003] In the stitching process, the substrate may be stained with oil on the edge due to improper storage and management of the substrate, or it may be bumped during transportation, resulting in uneven edges. Whether it is oil stains or uneven welding ends, it will affect the welding strength at the stitching point and may cause welding failures, thereby requiring production to be interrupted for adjustment and repair, reducing production efficiency; and the winter temperature in some areas is low, and the temperature of the cleaning fluid is too low, which slows down the rate of chemical reactions, reduces the cleaning ability, and has a poor cleaning effect on the substrate, affecting the subsequent spraying quality and causing an increase in the failure rate. Summary of the invention

[0004] The purpose of the present invention is to provide a production device for a highly corrosion-resistant water-based material color-coated plate and a color-coated plate, which can conveniently replace a cleaning roller.

[0005] The highly corrosion-resistant water-based material color-coated plate production device comprises an unwinder for transmitting the substrate to the right, and a first cleaning device is arranged on the right of the unwinder; The first cleaning device comprises a cleaning device housing, a first material passage opening for horizontally passing the substrate and communicating left and right is provided in the cleaning device housing, a cleaning roller for cleaning the substrate and capable of rotating left and right is longitudinally arranged in the cleaning device housing, the front and rear ends of the cleaning roller are detachably connected to a mounting frame, the front and rear ends of the mounting frame are both connected to the cleaning device housing in a rotating manner left and right, after the mounting frame rotates, the cleaning roller is located above the cleaning device housing, and a plurality of nozzles for spraying cleaning liquid are arranged in the cleaning device housing; A light curtain sensor is arranged on the right side of the first cleaning device, a first cutting machine is installed on the right side of the light curtain sensor, a stitching machine is arranged on the right side of the first cutting machine, a second cleaning device is arranged on the right side of the stitching machine, and a first drying machine is installed at the output end of the second cleaning device; The first dryer comprises a dryer shell, in which a hot water component is installed, and a liquid outlet of the hot water component is connected to a liquid inlet of the nozzle and a liquid inlet of the second cleaning device through a water pipe.

[0006] The substrate on the uncoiler first enters the first cleaning device, which cleans and dries the substrate. The substrate passes through the first cleaning device from the first feeding port to the right, and the nozzle sprays cleaning liquid on the substrate and the cleaning roller. The cleaning roller scrubs the substrate. Then the substrate passes through the light curtain sensor for detection to check whether the substrate is uneven and damaged. The unevenness of the welding end will affect the welding strength of the seam and cause unqualified welding. If the light curtain sensor detects that the end of the substrate to be welded is uneven, when the end enters the first cutting machine, the first cutting machine cuts off the uneven section of the end. Then enter the stitching machine for welding. The hot water component uses the heat in the dryer shell to heat the cleaning liquid sprayed by the nozzle, and heats the cleaning liquid required in the second cleaning device. When the ambient temperature is low, the cleaning liquid can also be kept at the temperature for the best cleaning effect; when the cleaning roller needs to be replaced, the mounting frame is rotated so that the cleaning roller is located above the cleaning device shell, and the cleaning roller is removed from the mounting frame for replacement. After the replacement is completed, the mounting frame is rotated so that the cleaning roller is located in the cleaning device shell to clean the substrate; This solution has the following four major effects: First, in the stitching machine The first cleaning of the substrate before welding not only reduces the impact of oil and other pollutants on the welding quality, but also improves the cleaning efficiency of the second cleaning equipment; second, 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 end when it is not flat, and then enter the stitching machine for welding, which further improves the welding quality, and does not need to stop production and adjust due to unqualified welding, thereby improving production efficiency; the light curtain sensor can also continuously monitor whether the substrate is damaged. If it is damaged, the damaged section is cut off by the first cutting machine and then welded by the stitching machine, which reduces the unqualified rate of the substrate and improves the production quality of the color-coated plate; third, the first drying machine used to dry the substrate after cleaning is used to heat the cleaning liquid used on the production line. When the ambient temperature is low, the cleaning liquid can also be kept at the temperature of the best cleaning effect, thereby improving the qualified rate of subsequent spraying and other processing; fourth, by rotating the mounting frame, the cleaning roller is rotated with the mounting frame to the top of the cleaning equipment housing, and 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 prevent the cleaning liquid sprayed by the nozzle from splashing everywhere.

[0007] Furthermore, two longitudinal fixed columns are symmetrically installed on the mounting frame at an interval up and down, the center line of the rotational connection between the mounting frame and the cleaning equipment housing coincides with the symmetry axis between the upper and lower fixed columns, the inner ends of the fixed columns are fixed with longitudinal studs, threaded holes that are threadedly matched with the studs are processed at the ends of the cleaning rollers, the studs on the lower side are respectively threadedly connected to the ends of the cleaning rollers, and the outer ends of the fixed columns independently pass through the mounting frame, and a disassembly and assembly component that drives the fixed column to rotate is installed on the cleaning equipment housing corresponding to the upper fixed column, and when the disassembly and assembly component drives the fixed column to rotate, it drives the stud to move forward and backward.

[0008] The stud is screwed into the threaded hole at the end of the cleaning roller and the cleaning roller is connected by thread. When the cleaning roller needs to be replaced, the mounting frame is rotated, and the cleaning roller is rotated to the top of the cleaning equipment housing. The upper and lower fixed columns on the upper and lower sides are swapped. After the mounting frame is rotated, the fixed column corresponding to the cleaning roller is located on the upper side to fix the cleaning roller. The disassembly and assembly component drives the fixed column corresponding to the cleaning roller to rotate, driving the stud to move outward and separate from the cleaning roller. The cleaning roller is removed and a new cleaning roller is put in. While the disassembly and assembly component drives the fixed column to rotate, it drives the stud to move inward and screw into the threaded hole at the end of the cleaning roller. The mounting frame is rotated to rotate the cleaning roller to the working position on the lower side. , thereby completing the convenient loading and unloading of the cleaning roller; in order to speed up the replacement speed, a cleaning roller can also be installed between the two fixed columns on the upper side. When replacing, the new cleaning roller can be put into use by simply rotating the mounting frame, further saving the replacement time of the cleaning roller; in actual use, a cleaning roller can also be installed in the cleaning equipment housing below the first material passing port to achieve double-sided scrubbing of the substrate. When there are two cleaning rollers, there are four fixed columns at one end of the two cleaning rollers, two of which 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 up and down with the fixed columns on the lower side.

[0009] Furthermore, the disassembly assembly component includes a cylinder that can be telescopically extended forward and backward, a disassembly motor is fixed on the piston rod of the cylinder, and the outer ends of the fixing columns are provided with disassembly holes that cooperate with the transmission shaft of the disassembly motor.

[0010] When the cleaning roller needs to be disassembled, the cylinder drives the rotating shaft of the disassembly and assembly motor to extend into the disassembly and assembly hole, the transmission shaft of the disassembly and assembly motor rotates, driving the stud to exit the threaded hole at the end of the cleaning roller. At the same time, the cylinder drives the disassembly and assembly motor to move outward, and the cleaning roller can be removed. When installing the cleaning roller, the transmission shaft of the disassembly and assembly motor rotates, driving the stud to extend into the threaded hole at the end of the fixed column. At the same time, the cylinder drives the disassembly and assembly motor to move inward, completing the rapid installation and disassembly of the cleaning roller. After the cleaning roller is installed, the mounting frame is rotated to drive the cleaning roller to the working position. The cylinder drives the disassembly and assembly motor to move inward, and the transmission shaft of the disassembly and assembly motor is inwardly pressed against the disassembly and assembly hole to limit the mounting frame to prevent rotation. The disassembly and assembly assembly not only realizes the convenient loading and unloading of the cleaning roller, but also limits the mounting frame, which is convenient to work.

[0011] Furthermore, gears are fixed to the outer ends of the fixing columns at the front side, and transmission gears meshing with the gears are arranged on the upper sides of the gears, and the transmission gears are connected to a driving motor driving the transmission gears to rotate.

[0012] The transmission gear is mounted on the transmission shaft of the driving motor. The driving motor drives the transmission gear to rotate, which in turn drives the gear to rotate, thereby driving the fixed column to rotate, thereby realizing the rotation of the cleaning roller and cleaning 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 frame. When replacing the cleaning roller, you only need to stop the driving motor to rotate the mounting frame to drive the gear to rotate, which further increases the convenience of replacing the cleaning roller.

[0013] Furthermore, a longitudinal cylindrical table is fixed on the mounting frame at the rotational connection with the cleaning equipment shell. The inner end of the cylindrical table is fixed to the mounting frame, and the outer end is rotationally connected to the cleaning equipment shell and is connected to a limiting cylinder after passing through the mounting frame, on which a rotating part is installed.

[0014] An internal thread is processed inside the limiting cylinder, and an external thread that matches the internal thread is processed on the outer end of the cylindrical table, so that the limiting cylinder is threadedly mounted on the cylindrical table. The rotating part can be a bolt, which can further tighten the limiting cylinder and the cylindrical table, and can also be used as a handle to facilitate the rotation of the mounting frame.

[0015] Furthermore, a collecting frame for temporarily placing the cleaning roller is detachably connected between the front and rear mounting frames.

[0016] When replacing the cleaning roller, rotate the mounting frame so that the cleaning roller is located above the outer shell of the cleaning equipment, and install the collection frame below the cleaning roller. If the cleaning roller is heavy, after the studs move outward, the cleaning roller can be directly dropped into the collection frame and then removed, which is more convenient.

[0017] Furthermore, a wind knife for drying the substrate is installed at the right end of the cleaning equipment casing. The air inlet end of the wind knife is connected to an air pump through an air supply pipe, the air outlet end of the air pump is connected to the air inlet end of the air supply pipe, and the air inlet end of the air pump is connected to the dryer casing through a pipeline.

[0018] The air pump delivers the heated air in the dryer housing to the air knife, which speeds up the cleaning of residual liquid on the substrate.

[0019] 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. A pressure block that can move up and down is arranged above each fixed seat. After the pressure block moves downward, the substrate is pressed down on the fixed seat. A cutting knife that can move up and down is installed between the two fixed seats.

[0020] After the pressing block moves down, the substrate is pressed down on the fixing seat, and the cutting knife moves downward to cut the substrate, and the head and tail sections of the substrate are cut off to improve the quality of the head and tail welding.

[0021] Furthermore, the collection frame is fixed to the mounting frame by fixing bolts, and the cylinder body of the cylinder is mounted on the cleaning equipment housing by the fixing frame; The bottom of the pressing block is connected to a first hydraulic rod that can be extended up and down, the bottom of the cutting knife is connected to a second hydraulic rod that can be extended up and down, a debris collection box is arranged below the cutting knife, a second material passage opening for the substrate to pass through and which is connected to the left and right is opened in the dryer shell, and a coating machine, a second drying machine, a second cutting machine and a winding machine are arranged in sequence at the outlet end of the second material passage opening, the substrate passes through the dryer shell and enters the coating machine for coating, and then enters the second drying machine for drying the coating to obtain a color-coated plate, the color-coated plate is divided into rolls by the second cutting machine, and the winding machine rolls up the divided color-coated plate; Auxiliary feeding mechanisms for assisting substrate transportation are provided between the unwinder and the first cleaning device, between the first cutting machine and the stitching machine, between the second cleaning device and the first drying machine, and between the second cutting machine and the winding machine.

[0022] The first hydraulic rod drives the pressure block to move up and down, and the second hydraulic rod drives the cutting knife to move up and down, which is convenient for control. The debris collection box is convenient for receiving the debris dropped by cutting; the fixing bolts facilitate the disassembly and assembly of the collection frame; the coating machine and the second dryer can be set with multi-stage coating and drying as needed; the number of auxiliary feeding mechanisms can be increased or decreased during actual use.

[0023] A color-coated plate is prepared according to the production device of the color-coated plate made of highly corrosion-resistant water-based material.

[0024] Compared with the prior art, the present invention has the following beneficial effects: First, the substrate is cleaned for the first time before the stitching machine is welded, which not only reduces the impact of oil and other pollutants on the welding quality, but also improves the cleaning efficiency of the second cleaning equipment; Second, 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 end by the first cutting machine if it is not flat, and then weld it in the stitching machine, which further improves the welding quality. There is no need to stop production and adjust due to unqualified welding, which improves production efficiency. The light curtain sensor can also continuously monitor whether the substrate is damaged. If it is damaged, the damaged section is cut off by the first cutting machine and then welded by the stitching machine, which reduces the unqualified rate of the substrate and improves the production quality of the color-coated plate. Third, the cleaning liquid used on the production line is heated by using the first drying machine for drying the substrate after cleaning. When the ambient temperature is low, the cleaning liquid can also be kept at the temperature for the best cleaning effect, thereby improving the qualification rate of subsequent spraying and other processing; Fourth, by rotating the mounting frame, the cleaning roller is rotated with the mounting frame to the top of the cleaning device housing, and the cleaning roller can be easily replaced without reaching into the cleaning device housing or opening the cleaning device housing. The cleaning device housing can prevent the cleaning liquid sprayed by the nozzle from splashing everywhere. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, the installation method of the light curtain sensor 3 is set to set two groups of light curtains on the front and rear sides and the upper and lower sides of the substrate 13 respectively; a group of light curtains on the front and rear sides are used to detect whether the substrate 13 is flat. If it is not flat, the light emitted by the emitting light curtain will be blocked, and the receiving light curtain will not receive the light emitted by the emitting light curtain, and output a blocked signal, indicating that the substrate 13 is uneven; a group of light curtains located on the upper and lower sides are used to detect whether the substrate 13 is damaged. If it is damaged, the light of the emitting light curtain will pass through the damaged point, and the receiving light curtain will receive the light emitted by the emitting light curtain, and output a damaged signal, indicating that the substrate 13 is damaged.

[0040] like Figure 1 As shown, a first cutting machine 4 is arranged on the right side of the light curtain sensor 3 .

[0041] like Figure 5As shown, the structure of the first cutting machine 4 is bilaterally symmetrical. The first cutting machine 4 includes a fixed seat 4.3, in which a hydraulic cylinder is installed. The push rod of the hydraulic cylinder is called a first hydraulic rod 4.2, and a pressure block 4.1 is fixed on the top of the first hydraulic rod 4.2. Figure 4 As shown, a cutting knife 4.5 is installed in the middle of the first cutting machine 4.

The push rod of the hydraulic cylinder is a second hydraulic rod 4.6. A debris collection box 4.4 for collecting cutting debris is arranged directly below the cutting knife 4.5.

[0042] like Figure 1 As shown, a stitching 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 stitching machine 5 .

[0043] The second cleaning device 6 is a known technology, including an acid cleaning area and a cleaning area. The acid cleaning area is used to degrease the substrate. The purpose of this step is to remove grease and dirt on the surface of the substrate to ensure the quality of subsequent processing; the cleaning area removes residual chemicals and impurities through alkaline washing and water washing to prepare for subsequent chemical conversion treatment. Figure 1 As shown, a first drying machine 7 is installed above the second cleaning device 6 .

[0044] The first dryer 7 is an existing technology, mainly composed of a dryer housing 7.1, a combustion furnace, a flue, a blower, a motor, a base and a flue gas discharge port. Figure 7 As shown, a second feed opening 7.3 is provided on the dryer housing 7.1, which passes through the left and right sides; Figure 4 As shown, a hot water assembly 7.2 is installed in the dryer housing 7.1. The hot water assembly 7.2 is connected by four hollow columns and a plurality of hollow circular tubes. The specific assembly method of the hot water assembly 7.2 is as follows Figure 8 and Fig. 9 As shown, the hollow columns on the front and rear sides are connected by three hollow circular tubes arranged side by side and vertically spaced, the columns on the left and right sides are connected by a horizontal hollow circular tube, and a water inlet pipe and a water outlet pipe are connected to one side of the column respectively, the liquid inlet end of the water inlet pipe is connected to the cleaning liquid pipe, and the liquid outlet end of the water outlet pipe is connected to the water delivery pipe 2.6; in actual use, the number of hot water components 7.2 is set according to the number of the first cleaning equipment 2 and the second cleaning equipment 6, and the structure can also be other detours.

[0045] On the left side of the first dryer 7, a coating machine 8 is installed. The coating machine 8 is a known technology in the art and usually evenly coats the surface of the substrate with paint by methods such as roll coating, curtain flow coating, or powder coating. On the left side of the coating machine 8, a second dryer 9 is installed. The structural principle of the second dryer 9 is the same as that of the first dryer 7. The water outlets of the hot water components 7.2 in the first dryer 7 and the second dryer 9 are respectively connected to the water delivery pipe 2.6 of the first cleaning device 2 and the water inlet of the second cleaning device 6 through pipelines.

[0046] As Figure 1 shown, on the left side of the second dryer 9, a second cutting machine 10 is installed. The second cutting machine 10 is a coil splitting machine, which is a known technology in the art and mainly consists of components such as a box body, a mounting plate, a sliding rod, a motor plate, a driving motor, and a cutting disc. The device drives the motor plate to move through a telescopic rod, and the cutting disc connected to the output shaft of the driving motor cuts the color-coated board.

[0047] On the left side of the second cutting machine 10, a rewinder 12 is installed. The rewinder 12 is located above the uncoiler 1. Both the uncoiler 1 and the rewinder 12 are known technologies in the art. The principle is that the coil material is placed on a telescopic drum, and after being tensioned by the telescopic drum, the motor drives the telescopic drum to rotate to drive the drum to uncoil. As Fig.10 shown, the first dryer 7, the coating machine 8, the second dryer 9, the second cutting machine 10, and the rewinder 12 are all installed above the uncoiler 1, the first cleaning device 2, the light curtain sensor 3, the first cutting machine 4, the sewing machine 5, and the second cleaning device 6 through a "冂"-shaped frame. And as Figure 1 shown, between the uncoiler 1 and the first cleaning device 2, between the first cutting machine 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, auxiliary feeding mechanisms 11 are installed, which mainly consist of mounting brackets and roller shafts to guide the substrate 13.

[0048] The usage instructions of the above technical solutions are specifically as follows: The working principle is as follows: As Figure 1 shown, first, the substrate 13 unrolled by the uncoiler 1 is guided through the auxiliary feeding mechanism 11 and inserted into the first material passing port 2.13 inside the first cleaning device 2. After the substrate 13 enters the first cleaning device 2, cleaning liquid is transported from the water delivery pipe 2.6, then the cleaning liquid is sprayed by the spray head 2.14, and then the substrate 13 is preliminarily cleaned by the cleaning roller 2.15 to wipe off impurities such as dust and grease. Then, the substrate 13 is dried by the air knife 2.7 to prevent impurities on the substrate 13 from affecting sewing and subsequent operations.

[0049] During the cleaning process, as Figure 4As shown, the piston rod of the cylinder 2.9.1 is pushed out, and the drive shaft of the disassembly motor 2.9.2 extends into the disassembly hole 2.21 on the fixing column 2.16 located above, thereby limiting the rotation of the mounting frame 2.4.

[0050] like Figure 1 As shown, when the substrate 13 passes through the light curtain sensor 3, the light curtain sensor 3 detects the flatness of the upper and lower surfaces of the substrate 13. If there are obvious gaps and damage, the first cutting machine 4 will then cut the substrate 13 to keep the end surface flat. Figure 5 As shown, the first hydraulic rod 4.2 drives the pressing 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 knife 4.5 to move downward 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.

[0051] After cutting, the substrate 13 is stitched by welding in the stitching machine 5, and then enters the second cleaning device 6 for cleaning. After cleaning, the substrate 13 enters the first drying machine 7, then enters the coating machine 8 for coating, and then enters the second drying machine 9 for drying again. After the secondary drying is completed, it is rolled by the second cutting machine 10 and then rolled by the winding machine 12.

[0052] According to production needs, the coating machine 8 and the second drying machine 9 can be installed again between the second drying machine 9 and the second cutting machine 10 to perform multiple coating processes until the product requirements are met, and then the coating machine 8 and the second drying machine 9 are divided into rolls by the second cutting machine 10 and then rewound by the reel 12.

[0053] The process of replacing the cleaning roller 2.15 in the first cleaning device 2 is as follows: After the cleaning roller 2.15 has worked for a period of time, its cleaning ability is reduced and it needs to be replaced regularly. The piston rod of the cylinder 2.9.1 is retracted, and then the mounting frame 2.4 is rotated so that the cleaning roller 2.15 to be replaced is located outside the cleaning device housing 2.1. The piston rod of the cylinder 2.9.1 is pushed out again, so that the drive shaft of the disassembly motor 2.9.2 enters the disassembly hole 2.21 of the fixed column 2.16. The motor works, and the rotating shaft screws the fixed column 2.16 outward. While the fixed column 2.16 moves, the piston rod of the cylinder slowly drives the motor to move outward until the cleaning roller 2.15 can be taken out; after replacing the cleaning roller 2.15, the disassembly assembly 2.9 screws the fixed column 2.16 inward to fix the cleaning roller 2.15.

[0054] Specifically, when the cleaning roller 2.15 needs to be replaced, the mounting frame 2.4 is rotated, and the cleaning roller 2.15 is rotated to the top of the cleaning equipment housing 2.1, and the two fixing columns 2.16 are swapped in upper and lower positions. After the mounting frame 2.4 is rotated, the fixing column 2.16 corresponding to the cleaning roller 2.15 is located on the upper side, fixing the cleaning roller 2.15, and the disassembly and assembly component 2.9 drives the fixing column 2.16 corresponding to the cleaning roller 2.15 to rotate, driving the stud 2.19 to move outward and separate from the cleaning roller 2.15, and the cleaning roller 2.15 is removed. After the new cleaning roller 2.15 is put in, the disassembly and assembly component 2.9 drives the fixing column 2.16 to rotate, while driving the stud 2.19 to move inward and screw into the threaded hole at the end of the cleaning roller 2.15, and the mounting frame 2.4 is rotated to rotate the cleaning roller 2.15 to the lower side. working position, thereby completing the convenient loading and unloading of the cleaning roller 2.15; in order to speed up the replacement speed, a cleaning roller 2.15 can also be installed between the two fixing columns 2.16 on the upper side. When replacing, the new cleaning roller 2.15 can be put into use by simply 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 in the cleaning equipment housing 2.1 below the first feeding port 2.13 to achieve double-sided scrubbing of the substrate 13. When there are two cleaning rollers 2.15, there are four fixing columns 2.16, two of which are used to connect the cleaning roller 2.15, and the other two are located above the rotation connection between the mounting frame 2.4 and the cleaning equipment housing 2.1, and are symmetrically distributed downward with the fixing columns 2.16 on the lower side.

[0055] The hot water component 7.2 can use the heat of the first dryer 7 to preheat the cleaning liquid delivered by the water inlet pipe, and then deliver it to each nozzle 2.14 through the water outlet pipe and the water delivery pipe 2.6 to improve its cleaning effect. Before the substrate 13 is sutured, it is cleaned and the end surface is cut, and the suture effect is good. Production can also be carried out when the cleaning roller 2.15 is replaced, which can reduce downtime and improve production efficiency.
