Description

Technical Field

[0001] This application relates to the field of coating technology, and in particular to a coating apparatus. Background Technology

[0002] Coating equipment is mainly used for surface coating processes of materials such as paper and film. It generally includes a coating head, unwinding mechanism, traction mechanism, drying oven and rewinding mechanism. The unwinding mechanism causes the rolled substrate to be coated under the drive of the traction mechanism, that is, a layer of adhesive, paint or ink with specific functions is coated on the substrate. After drying in the drying oven, it is cut into sheets or rewound.

[0003] When applying a surface coating to a substrate, the substrate surface needs to be dried in a drying oven. To accelerate the drying process, existing coating equipment typically includes multiple drying ovens. While having multiple drying ovens installed in the factory can improve the surface drying effect, it also requires a large floor space, thus reducing the factory's space utilization. Summary of the Invention

[0004] In order to improve the space utilization of the factory, this application provides a coating equipment that maximizes the utilization of factory space.

[0005] The coating equipment provided in this application adopts the following technical solution: A coating apparatus includes a frame, a coating device, and a drying device. The coating device is located at the bottom of the frame, and the drying device is located at the top of the frame. The coating device includes a first coating mechanism and a second coating mechanism, and the drying device includes a first drying chamber and a second drying chamber arranged vertically.

[0006] By adopting the above technical solution, the first and second drying boxes, which are arranged vertically, are used to coat the substrate once on the first coating mechanism. After coating, the substrate is pulled into the second drying box for drying. After drying, the substrate is coated a second time on the second coating mechanism. After coating, the substrate is pulled into the first drying box for drying again, thereby achieving the drying effect. At the same time, the vertical folding arrangement can effectively reduce the space ratio of the drying device, thereby improving the space utilization rate of the factory.

[0007] In one specific implementation, the first drying oven includes an upper layer and a lower layer, the upper layer and the lower layer are rotatably connected, and the lower layer is hinged with a plurality of first lifting cylinders, the lifting rods of the first lifting cylinders being hinged to the upper layer.

[0008] By adopting the above technical solution, a first drying box with two openable layers is set up. The upper layer of the first drying box is driven to rise by the first lifting cylinder, thereby separating the upper and lower layers of the first drying box, which facilitates the maintenance and repair of the first drying box by the staff.

[0009] In one specific implementation scheme, the first drying box and the second drying box are each provided with a number of traction rollers 3. There are also a number of traction rollers 3 between the first drying box and the second drying box. One end of each traction roller 3 is fitted with a transmission wheel. The transmission wheels are connected to a transmission belt. One of the transmission wheels is connected to a third drive motor mounted on the frame.

[0010] By adopting the above technical solution, a third drive motor drives one of the transmission wheels to rotate, which in turn drives the transmission belt connected to the transmission wheel to rotate. This causes the other transmission wheels mounted on the transmission belt to rotate simultaneously. The simultaneous rotation of the transmission wheels can drive the first drying box, the second drying box, and the traction roller between the first and second drying boxes to rotate, thereby realizing the movement of the drying device.

[0011] In one specific implementation scheme, the first coating mechanism includes a third support frame, the third support frame is provided with a plurality of traction rollers and a second drive motor for driving one of the traction rollers to rotate, the third support frame is provided with a paint roller and a movable column, the movable column is hinged to an angle adjusting cylinder, the angle adjusting cylinder is connected to a mounting plate, the mounting plate is provided with an adjusting plate, the adjusting plate is provided with a paint trough, and the paint trough is rotatably connected to the third support frame; The second coating mechanism includes a fourth support frame, which is provided with a plurality of traction rollers and a second drive motor for driving one of the traction rollers to rotate. The fourth support frame is provided with a coating roller and a movable column. The movable column is hinged to an angle adjusting cylinder. The angle adjusting cylinder is connected to a mounting plate. The mounting plate is provided with an adjusting plate. The adjusting plate is provided with a coating tank. The coating tank is rotatably connected to the fourth support frame.

[0012] By adopting the above technical solution, a second drive motor drives one of the traction rollers to rotate, causing the other traction rollers to rotate simultaneously under the influence of the substrate, thus realizing the transfer of the substrate within the first coating mechanism. Simultaneously, an angle-adjusting cylinder is used to adjust the angle of the adjusting plate. When the angle-adjusting cylinder is activated, its extension rod drives the mounting plate to rise and fall, thereby simultaneously raising and lowering the adjusting plate located on the mounting plate. The rising and falling of the adjusting plate causes one end of the paint tank connected to the adjusting plate to rotate. Since the other end of the paint tank is rotatably connected to the third support frame, this further drives the angle adjustment of the paint tank. By adjusting the angle of the paint tank, accurate coating thickness is achieved for subsequent coating rollers on the substrate.

[0013] A second drive motor drives one of the traction rollers to rotate, causing the other traction rollers to rotate simultaneously under the influence of the substrate, thus conveying the substrate within the second coating mechanism. Simultaneously, an angle-adjusting cylinder adjusts the angle of the adjusting plate. When the cylinder is activated, its extension rod raises and lowers the mounting plate. This movement of the adjusting plate rotates one end of the coating tank connected to it. Since the other end of the coating tank is rotatably connected to the third support frame, this also adjusts the angle of the coating tank. By adjusting the angle of the coating tank, accurate coating thickness is achieved for subsequent coating rollers on the substrate.

[0014] In one specific implementation scheme, the system further includes an unwinding mechanism, which includes a first support frame, an unwinding reel on the first support frame, a plurality of unwinding rollers on the unwinding reel, an unwinding motor on one side of the first support frame, and the output shaft of the unwinding motor being connected to the unwinding reel.

[0015] By adopting the above technical solution, the unwinding motor drives the unwinding reel to rotate, causing several unwinding rollers on the unwinding reel to rotate simultaneously. When one unwinding roller finishes unwinding, the unwinding reel is rotated to move another unwinding roller to the next process to continue unwinding, thereby achieving continuous unwinding without stopping the machine.

[0016] In one specific implementation scheme, the system further includes a first traction mechanism, which includes a second support frame. The second support frame is provided with a connecting frame, and the connecting frame is provided with a traction frame for conveying the substrate. A first telescopic cylinder is hinged to the connecting frame, and the telescopic rod of the first telescopic cylinder is hinged to the traction frame. The second support frame is provided with a plurality of traction rollers, and the second support frame is also provided with a first drive motor for driving one of the traction rollers to rotate.

[0017] By adopting the above technical solution, when the unwinding roller of the previous process moves to the traction frame, the first telescopic cylinder is used to rotate the traction frame, so that the substrate is in a tensioned state; at the same time, the first drive motor is used to drive one of the traction rollers to rotate, so that the other traction rollers are conveyed under the drive of the substrate, and reach the first coating mechanism through the traction rollers to proceed to the next process.

[0018] In one specific implementation scheme, a correction mechanism is also included, which includes a fifth support frame. The fifth support frame is rotatably connected to two mounting seats, and a correction roller is connected between the two mounting seats. A second telescopic cylinder is hinged on the fifth support frame, and the piston rod of the second telescopic cylinder is hinged to one of the mounting seats. A first sensor is provided on the fifth support frame, and the first sensor and the second telescopic cylinder are connected to a controller.

[0019] By adopting the above technical solution, the second telescopic cylinder drives one of the mounting seats to rotate, thereby causing the correction roller located between the two mounting seats to move simultaneously; the correction mechanism also includes a first sensor. When the first sensor senses a deviation in the substrate conveying direction, the first sensor transmits a signal to the controller. After receiving the signal, the controller controls the second telescopic cylinder to rotate, thereby correcting the deviation of the substrate and achieving the correction process of the correction mechanism.

[0020] In one specific implementation, the fifth support frame is further provided with a plurality of traction rollers and a fourth drive motor for driving one of the traction rollers to rotate, and the fifth support frame is further provided with a plurality of second cooling fans for dissipating heat from the substrate.

[0021] By adopting the above technical solution, the fourth drive motor drives one of the traction rollers to rotate, so that the other traction rollers rotate simultaneously under the drive of the substrate, thereby realizing the transfer of the substrate in the correction mechanism; at the same time, several second cooling fans are provided to help dissipate the heat of the substrate that has just been transferred from the first drying box to the correction mechanism.

[0022] In one specific implementation scheme, a second traction mechanism is also included, which includes a sixth support frame with a plurality of traction rollers on the sixth support frame and a first drive motor for driving one of the traction rollers to rotate.

[0023] By adopting the above technical solution, the first drive motor drives one of the traction rollers to rotate, thereby causing the other traction rollers to be conveyed under the drive of the substrate and reach the next process through the traction rollers.

[0024] In one specific implementation scheme, a water coating mechanism is also included. The water coating mechanism includes an eighth support frame, which is provided with a plurality of traction rollers and a fifth drive motor for driving one of the traction rollers to rotate. The eighth support frame is provided with a water storage tank, a hydrophilic roller, and a coating roller. The hydrophilic roller and the coating roller are both provided with a sixth drive motor. The eighth support frame is also provided with a plurality of first cooling fans for dissipating heat from the substrate.

[0025] By adopting the above technical solution, the fifth drive motor drives one of the traction rollers to rotate, so that the substrate is conveyed to the coating roller. The sixth drive motor drives the hydrophilic roller and the coating roller to rotate. During the rotation, the hydrophilic roller is coated with water from the water storage tank and then coated onto the substrate, thereby completing the back coating process of the substrate. At the same time, several first cooling fans are set up to dissipate heat and dry the substrate that has just been conveyed from the second drying box to the coating mechanism and has undergone the back coating process.

[0026] In one specific implementation scheme, a winding mechanism is further included. The winding mechanism includes a seventh support frame, on which a guide roller, a power roller, and a rotatable first support frame located on one side of the power roller are provided. A first winding roller is supported on the first support frame. A first mounting frame is connected to the seventh support frame. A power cylinder is provided on the first mounting frame. A support claw is provided on the power cylinder. The support claw supports a second winding roller. A break line is provided on the second winding roller. One end of the break line is connected to the second winding roller, and the other end passes under the substrate and is connected to the second winding roller. A wire mounting tube located under the substrate is provided on the seventh support frame for placing the break line. A rotatable second support frame is also provided on the seventh support frame.

[0027] By adopting the above technical solution, the substrate is guided and conveyed using guide rollers. When the substrate needs to be wound up, the first winding roller comes into contact with the power roller, and the power roller drives the first winding roller to wind up. At the same time, a power cylinder and a support claw are set up so that the second winding roller located on the support claw can be raised and lowered by the power cylinder and come into contact with the power roller. This allows the power roller to drive the second winding roller to rotate, thereby gradually tightening the cutting line. The substrate is then cut by the tightened cutting line, and the winding is completed. At the same time, the first support frame drives the first winding roller, which has completed winding, to rotate, so that the first winding roller rolls to the second support frame, making it easy for the operator to remove the first winding roller. This achieves rapid winding as a whole and reduces the number of downtimes of the winding mechanism.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. This application utilizes a first drying chamber and a second drying chamber arranged vertically, so that after the substrate is coated once on the first coating mechanism, it is transferred to the second drying chamber for a first drying. After the first drying, it is transferred to the second coating mechanism for a second coating. After the second coating, it is transferred to the first drying chamber for a second drying. The drying effect is improved by the two drying processes. At the same time, the vertical folding arrangement effectively reduces the space ratio of the drying device and improves the space utilization rate of the factory.

[0029] 2. This application provides a first drying chamber with two openable layers. The upper layer of the first drying chamber is driven to rise by a first lifting cylinder, thereby separating the upper and lower layers of the first drying chamber, which facilitates maintenance and repair of the first drying chamber by the staff.

[0030] 3. This application utilizes an angle-adjusting cylinder to adjust the angle of the adjusting plate. When the angle-adjusting cylinder is activated, the telescopic rod of the angle-adjusting cylinder drives the mounting plate to rise and fall, thereby causing the adjusting plate located on the mounting plate to rise and fall simultaneously, which in turn drives the coating tank to adjust its angle. By adjusting the angle of the coating tank, the coating thickness can be accurately achieved for the subsequent coating roller to coat the substrate. Attached Figure Description

[0047] The following is in conjunction with the appendix Figure 1-15 This application will be described in further detail.

[0048] This application discloses a coating device.

[0049] Reference Figure 1A coating apparatus includes a frame 1, an unwinding mechanism 4, a traction device 5, a coating device 2, a water-coating mechanism 7, a drying device 3, a web-correcting mechanism 6, and a winding mechanism 8. The unwinding mechanism 4, traction device 5, coating device 2, water-coating mechanism 7, web-correcting mechanism 6, and winding mechanism 8 are all located below the frame 1, while the drying device 3 is located at the top of the frame 1. The traction device 5 includes a first traction mechanism 51 and a second traction mechanism 52. The first traction mechanism 51 is located between the unwinding mechanism 4 and the coating device 2, and conveys the unwound substrate to the coating device 2. The second traction mechanism 52 is located between the web-correcting mechanism 6 and the winding mechanism 8, and conveys the substrate to the winding mechanism 8 for winding.

[0050] Reference Figure 2 and Figure 3 The unwinding mechanism 4 includes a first support frame 41, on which an unwinding reel 42 is mounted. The unwinding reel 42 has several unwinding rollers 43. A driven gear 452 is fitted onto one side of the unwinding reel 42. An unwinding motor 44 is mounted on one side of the first support frame 41. A driving gear 451 is fitted onto the output shaft of the unwinding motor 44. An unwinding belt 453 is connected to the driving gear 451 and the driven gear 452. Starting the unwinding motor 44 drives the driving gear 451 to rotate, causing the unwinding belt 453 and the driven gear 452 connected to it to rotate simultaneously. This drives the unwinding reel 42 to rotate, and the rotation of the unwinding belt 453 drives the several unwinding rollers 43 on the unwinding reel 42 to rotate simultaneously. When one unwinding roller 43 finishes unwinding, rotating the unwinding reel 42 moves another unwinding roller 43 to the next process position for continued unwinding, thus achieving continuous unwinding without stopping the machine.

[0051] Reference Figure 2 and Figure 4 The first traction mechanism 51 includes a second support frame 511, which has a connecting frame 512. The connecting frame 512 has a traction frame 513 and a guide plate 515 for conveying the substrate. The traction frame 513 and the connecting frame 512 are rotatably connected by a connecting shaft. A first telescopic cylinder 514 is hinged to the connecting frame 512, and the telescopic rod of the first telescopic cylinder 514 is hinged to the traction frame 513. When it is necessary to adjust the tension of the substrate, the traction frame 513 can be rotated by the first telescopic cylinder 514 to adjust the tension of the substrate. The second support frame 511 has several traction rollers 53 and a first drive motor 54 for driving two or three of the traction rollers 53 to rotate. The first drive motor 54 is started, causing the traction rollers 53 to rotate, thereby allowing the substrate to pass through the traction rollers 53 to reach the first coating mechanism 21 for the next process.

[0052] The second support frame 511 is also equipped with a second sensor 516. The second sensor 516 is located on the side away from the traction frame 513 and is used to detect whether the substrate has entered the first traction mechanism 51. When the second sensor 516 senses the substrate, it can control the first drive motor 54 to start. The first drive motor 54 drives the traction roller 53 to rotate so that the substrate is traction and conveyed inside the first traction mechanism 51.

[0053] Reference Figure 5 and Figure 6 The coating apparatus 2 includes a first coating mechanism 21 and a second coating mechanism 22. A frame 1 is equipped with several traction rollers 33. The first coating mechanism 21 includes a third support frame 211, and is equipped with several traction rollers 231 and a second drive motor 232 for driving one of the traction rollers 231 to rotate. By activating the second drive motor 232, one of the traction rollers 231 can be driven to rotate, thereby drawing the substrate into the first coating mechanism 21 for coating and transport within it. Figure 7 The third support frame 211 is equipped with a paint roller 233 and two to three movable columns 234. A second lifting cylinder 239 is connected between two movable columns 234. An angle adjusting cylinder 235 is hinged to the movable column 234. An installation plate 236 is hinged to the telescopic rod of the angle adjusting cylinder 235. An adjusting plate 237 is connected to the end of the installation plate 236 away from the angle adjusting cylinder 235. The adjusting plate 237 has two sliding adjusting columns 240 inside. The adjusting columns 240 are connected to a paint tank 238. The paint tank 238 is located on the third support frame 211 and is rotatably connected to the third support frame 211 through a rotating shaft. The paint tank 238 abuts against the paint roller 233. A material receiving trough 241 located below the paint roller 233 is connected to the third support frame 211.

[0054] The height of the adjusting plate 237 on the movable column 234 can be adjusted by driving the second lifting cylinder 239 to raise and lower the movable column 234. On one hand, the angle adjusting cylinder 235 adjusts the angle of the adjusting plate 237. When the angle adjusting cylinder 235 is activated, the telescopic rod of the angle adjusting cylinder 235 drives the mounting plate 236 to rise and fall, thereby raising and lowering the adjusting plate 237 on the mounting plate 236 at the same time. The raising and lowering of the adjusting plate 237 can drive the rotation of one end of the paint tank 238 connected to the adjusting plate 237. Since the other end of the paint tank 238 is set on the third support frame 211 and is rotatably connected to the third support frame 211, the angle of the paint tank 238 can be adjusted. On the other hand, the adjusting column 240 can push the paint tank 238 through the inclined adjusting plate 237, thereby moving the paint tank 238 in the left and right directions. By adjusting the coating tank 238 in various directions and angles, the coating tank 238 coats the coating roller 233 through the material receiving tank 241, and then the coating liquid on the coating roller 233 is applied to the substrate, so as to ensure the accuracy of the coating thickness while coating the substrate.

[0055] Reference Figure 8 and Figure 9 The drying device 3 includes a first drying chamber 31 and a second drying chamber 32 arranged vertically. The first drying chamber 31 includes an upper layer 311 and a lower layer 312, which are rotatably connected by a hinge. Several first lifting cylinders 313 are hinged to the lower layer 312, and the lifting rods of the first lifting cylinders 313 are hinged to the upper layer 311. The first lifting cylinders 313 drive the upper layer 311 to rise, thereby opening the first drying chamber 31, which facilitates maintenance and repair of the first drying chamber 31 by the staff.

[0056] The first drying chamber 31 and the second drying chamber 32 are each equipped with several traction rollers 33. Several more traction rollers 33 are also provided between the first drying chamber 31 and the second drying chamber 32. One end of each traction roller 33 is fitted with a transmission wheel 34. Several transmission wheels 34 are connected to a transmission belt 35. A third drive motor 36 is mounted on the frame 1. The output shaft of the third drive motor 36 is connected to one of the traction rollers 33. Starting the third drive motor 36 drives one of the traction rollers 33 to rotate, thereby causing the transmission belt 35 and the transmission wheels 34 fitted on the transmission belt 35 to rotate simultaneously. The simultaneous rotation of the transmission wheels 34 drives the first drying chamber 31, the second drying chamber 32, and the traction rollers 33 between the first drying chamber 31 and the second drying chamber 32 to rotate, thus causing the substrate to move within the drying device 3.

[0057] Reference Figure 10After the substrate is coated by the first coating mechanism 21, it enters the second drying chamber 32 for drying. After drying, it is moved to the water coating mechanism 7 for water coating. The water coating mechanism 7 includes an eighth support frame 71, which is equipped with several traction rollers 72 and a fifth drive motor 73 for driving one of the traction rollers 72 to rotate. The fifth drive motor 73 is started to drive one of the traction rollers 72 to rotate, so that the substrate is conveyed to the water coating area under the drive of the traction roller 72. The eighth support frame 71 is equipped with a water storage tank 74, a hydrophilic roller 75, and a coating roller 76. Both the hydrophilic roller 75 and the coating roller 76 are equipped with a sixth drive motor 77. The eighth support frame 71 is also equipped with several first cooling fans 78 for heat dissipation of the substrate. The sixth drive motor 77 is started to drive the hydrophilic roller 75 and the coating roller 76 to rotate. During the rotation, the hydrophilic roller 75 is coated with water in the water storage tank 74 and then coated onto the substrate by the rotating hydrophilic roller 75, thereby completing the back coating process of the substrate. At the same time, several first cooling fans 78 are set up to dissipate heat and dry the substrate that has just been transferred from the second drying box 32 to the coating mechanism 7 and has undergone the back coating process.

[0058] Reference Figure 9 and Figure 11 The substrate, after being coated with water by the water coating mechanism 7, passes between the first drying chamber 31 and the second drying chamber 32 and moves to the second coating mechanism 22 for coating. The second coating mechanism 22 includes a fourth support frame 221, and is equipped with several traction rollers 231 and a second drive motor 232 for driving one of the traction rollers 231 to rotate. By activating the second drive motor 232, the second drive motor 232 can drive one of the traction rollers 231 to rotate, thereby bringing the substrate into the first coating mechanism 21 for coating and conveying. The second coating mechanism 22 and the first coating mechanism 21 have the same structure and both perform the coating function. The specific structure of the second coating mechanism can be referred to the first coating mechanism 21.

[0059] Reference Figure 11 and Figure 12The frame 1, located between the first coating mechanism 21 and the second coating mechanism 22, is also equipped with a correction assembly. The correction assembly includes a mounting base 62, a correction roller 63, a second telescopic cylinder 64, and a first sensor 65. A fixed plate 60 is provided on the frame 1. Two mounting bases 62 are connected to the fixed plate 60 via a rotating shaft and a rotating plate 601. A rotatable correction roller 63 is connected between the two mounting bases 62. A second telescopic cylinder 64 is hinged to the rotating plate 601. The piston rod of the second telescopic cylinder 64 is hinged to one of the mounting bases 62. A first sensor 65 is provided on the fifth support frame 61. The first sensor 65 and the second telescopic cylinder 64 are connected to a controller 66. After the substrate is conveyed out of the second drying chamber 32, the second telescopic cylinder 64 drives one of the mounting seats 62 to rotate, causing the correction roller 63 located between the two mounting seats 62 to move simultaneously, thus completing the correction of the substrate. When the first sensor 65 senses that the substrate conveying direction has deviated, the first sensor 65 transmits a signal to the controller 66. After receiving the signal, the controller 66 controls the second telescopic cylinder 64 to rotate, thereby correcting the deviation of the substrate, so that the substrate enters the second coating mechanism 22 after correction.

[0060] Reference Figure 8 and Figure 13 The correction mechanism 6 includes a fifth support frame 61, which is also equipped with a correction component. When the substrate is conveyed out of the first drying box 31, the second telescopic cylinder 64 is driven to rotate one of the mounting seats 62, so that the correction roller 63 located between the two mounting seats 62 moves simultaneously to complete the correction of the substrate. When the first sensor 65 senses that the substrate conveying direction has deviated, the first sensor 65 transmits a signal to the controller 66. After receiving the signal, the controller 66 controls the second telescopic cylinder 64 to rotate, thereby correcting the deviation of the substrate and achieving the correction process of the correction mechanism 6.

[0061] The fifth support frame 61 is also equipped with several traction rollers 67 and a fourth drive motor 68 for driving one of the traction rollers 67 to rotate. By starting the fourth drive motor 68 to drive one of the traction rollers 67 to rotate, the other traction rollers 67 rotate simultaneously under the drive of the substrate, realizing the conveying of the substrate within the correction mechanism 6; the fifth support frame 61 is also equipped with several second cooling fans 69 for dissipating heat from the substrate, so that the substrate can dissipate heat during the conveying process.

[0062] Reference Figure 8The second traction mechanism 52 includes a sixth support frame 521, on which several traction rollers 53 are mounted. The sixth support frame 521 also has a first drive motor 54 for driving one of the traction rollers 53 to rotate. Activating the first drive motor 54 causes one of the traction rollers 53 to rotate, thereby causing the other traction rollers 53 to be conveyed under the influence of the substrate. The substrate eventually reaches the winding mechanism 8 via the traction rollers 53, initiating the winding process. A pedal 9 connects the second traction mechanism 52 and the winding mechanism 8, allowing the substrate to be conveyed from the second traction mechanism 52 to the winding mechanism 8.

[0063] Reference Figure 14 and Figure 15 The winding mechanism 8 includes a seventh support frame 81, on which a guide roller 82, a power roller 83, and a rotatable first support frame 84 located on one side of the power roller 83 are mounted. A first gear 813 is fitted onto one end of the power roller 83. A power motor 812 is mounted on the seventh support frame 81, and a second gear 814 is fitted onto the output shaft of the power motor 812. The first gear 813 and the second gear 814 mesh. A first winding roller 85 is supported on the first support frame 84. A third telescopic cylinder 815 is hinged to the seventh support frame 81, and the telescopic rod of the third telescopic cylinder 815 is hinged to the first support frame 84. The seventh support frame 81 is provided with a rotatable second support frame 810. One end of the second support frame 810 is connected to a seventh drive motor 816 located on the seventh support frame 81. The seventh support frame 81 is provided with a rotatable first mounting frame 86. The first mounting frame 86 is provided with a power cylinder 87. The piston rod of the power cylinder 87 is provided with a support claw 817. The support claw 817 supports a second take-up roller 88. The second take-up roller 88 is provided with a cutting line 89. One end of the cutting line 89 is connected to the second take-up roller 88, and the other end passes through the substrate and is connected to the second take-up roller 88. The seventh support frame 81 is provided with a mounting tube 811 located below the substrate for placing the cutting line 89. The mounting tube 811 has an opening for the cutting line 89 to be removed from the mounting tube 811. The second take-up roller 88 is also provided with adhesive.

[0064] When the substrate reaches the winding process, the guide roller 82 guides and conveys the substrate, while simultaneously bringing the first winding roller 85 into contact with the power roller 83. The power motor 812 is started to rotate the power roller 83, which in turn drives the first winding roller 85 to wind up. After the first winding roller 85 completes winding, the power cylinder 87 on the first mounting frame 86 drives the second winding roller 88 to move down. The second winding roller 88 then comes into contact with the power roller 83, which in turn drives the second winding roller 88 to rotate. As the second winding roller 88 rotates, it winds up the cut wire 89. When the tightened cut wire 89 contacts the strip, the strip is cut by the tightened cut wire 89. At this point, the second winding roller 88 uses the adhesive on its surface to hold the end of the strip in place, and then begins winding up as the second winding roller 88 rotates with the power roller 83.

[0065] The third telescopic cylinder 815 is activated, pushing the first support frame 84 to rotate, thereby moving the first take-up roller 85 away from the power roller 83. The first support frame 84 moves the first take-up roller 85 to the second support frame 810, where it rolls to allow workers to remove it. The entire winding process does not require machine downtime. After the second take-up roller 88 finishes winding, the machine can be stopped once. Then, a new take-up roller is placed on the first mounting frame 86, and the cutting line 89 is installed in the cable mounting tube 811, reducing the number of downtimes and improving winding efficiency.

[0066] The implementation principle of this application embodiment is as follows: When it is necessary to coat the substrate, the unwinding motor 44 drives the unwinding reel 42 to unwind the substrate. After unwinding, it is pulled by the first traction mechanism 51 to the first coating mechanism 21. By adjusting the coating tank 238 provided in the first coating mechanism 21 in various directions and angles, the coating tank 238 coats the coating roller 233 through the material receiving groove 241, and then the coating liquid on the coating roller 233 is applied to the substrate, realizing the first coating of the substrate. After the first coating, it is pulled by the second traction roller 231 to the second drying box 32 for drying. After drying in the second drying box 32, it is conveyed to the water coating mechanism 7, and is driven by the sixth drive motor 77. The water roller 75 and the coating roller 76 rotate. During rotation, the hydrophilic roller 75 absorbs water from the water storage tank 74 and coats the substrate, thus completing the back coating process. After back coating, the substrate is pulled by the traction roller 33 between the first drying box 31 and the second drying box 32, and then pulled to the second coating mechanism 22 for secondary coating. Before the secondary coating, a correction is performed. After the secondary coating, the substrate enters the first drying box 31 through the traction roller 231 for drying. After being conveyed out of the first drying box 31, a second correction is performed. After the correction, the substrate enters the winding mechanism 8 through the second traction mechanism 52 and is wound up by the winding mechanism 8. The two drying processes improve the drying effect, and the folding drying device 3 reduces the space occupied by the drying device 3, improving the space utilization of the factory.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
