Description

Technical Field

[0001] The invention relates to the technical field of impregnated paper processing devices, and in particular to an impregnated paper impregnation drying cutting machine and a cutting method. Background Art

[0002] Impregnated paper is made of non-woven wood pulp mixed with PE and plant fiber. It has super absorbent and anti-dissolution ability. It is also a very economical low-particle release paper towel. It is widely used in the veneer of cabinets, wardrobes, and laminate flooring. When producing impregnated paper, a dry cutting machine is required to dry and cut the impregnated paper after impregnation.

[0003] The impregnated paper is made by installing the raw paper roll on a passive rolling shaft. The front end of the paper moves forward under the drive of the active paper roller driven by the motor transmission mechanism, and the paper roll is passively rotated and unwound. The forward paper enters the impregnation tank filled with impregnation liquid under the guidance of the guide roller, and is impregnated on both sides in the tank, and then enters the dryer from the end of the impregnation tank for drying.

[0004] However, the existing impregnated paper drying equipment generally adopts air drying or direct high-temperature heating and drying. The air drying method will cause the paper to shake when it is rolled up, so that the roll is wrinkled and uneven. The high-temperature heating and drying method will cause the paper to shrink and deform, so that the production of impregnated paper cannot meet the requirements. Moreover, when cutting after drying, directly using a cutting device to cut the impregnated paper will cause the tensioned impregnated paper to relax, which will also cause the impregnated paper to need to be arranged when rolling up next time, resulting in low production efficiency. Therefore, the present invention solves the shortcomings of the above technical problems. Summary of the invention

[0005] Based on the above existing technical problems, the present invention proposes an impregnated paper impregnation drying cutting machine and a cutting method.

[0006] The present invention proposes an impregnated paper impregnation drying and cutting machine, comprising guide rollers for guiding the produced impregnated paper, an impregnation tank is arranged between two groups of the guide rollers, the inner surface of the impregnation tank is rotatably connected to a pressing roller via a bearing, an air-heating and drying mechanism is arranged on one side of the impregnation tank, a clamping mechanism is arranged at the conveying front end of the air-heating and drying mechanism, and a winding mechanism is arranged at the conveying front end of the clamping mechanism.

[0007] The impregnated paper impregnated in the impregnation tank passes through the wind-heating and drying mechanism pair, and the impregnated paper is dried by the uniform speed wind heating provided by the wind-heating and drying mechanism.

[0008] The clamping mechanism presses the cut surface of the cut impregnated paper so that the impregnated paper remains taut.

[0009] The winding mechanism winds up the dried impregnated paper and opens one side of the winding shaft to take out the material.

[0010] Preferably, the air-heating and drying mechanism comprises an air shower box supported by support rods distributed in a rectangular array, a feed hole is penetrated through a surface of one side of the air shower box close to the adjacent guide roller, a conical water-passing shell is penetrated through a lower surface of the air shower box, and a water receiving tray is fixedly connected to the lower surface of the water-passing shell.

[0011] Through the above technical scheme, the forward impregnated paper enters the impregnation tank filled with impregnation liquid under the guidance of the guide roller, and is double-sidedly impregnated in the tank with the assistance of the pressing roller, and then enters the wind-heated drying mechanism from the end of the impregnation tank through another guide roller for drying. In order to dry the impregnated paper without damage, the impregnated paper enters the air shower box from the feed hole. Since the impregnated paper is suspended in the air, the impregnated paper can be drained. In order to prevent the drained water from accumulating in the air shower box and causing a bad internal environment that is inconvenient for the next drying of the impregnated paper, a conical water-passing shell is provided, and its inner wall is coated with a hydrophobic coating, so that the drained water can flow into the water receiving tray through the water-passing shell.

[0012] Preferably, the air-heating and drying mechanism also includes a rolling water slope fixedly connected to the inner bottom wall of the water receiving tray, the bottom end of the rolling water slope is fixedly connected to a water outlet pipe with a water outlet valve, and the upper surface of the air shower box is equipped with circulating fans distributed in a rectangular array.

[0013] Through the above technical scheme, in order to drain the water leaked from the impregnated paper as quickly as possible, the impregnated water falling into the water receiving tray flows from the surface of the rolling water slope to the water outlet pipe for discharge, and in order to speed up the drying of the impregnated paper, multiple circulating fans are synchronized to blow circulating air into the air shower box.

[0014] Preferably, the air-heating and drying mechanism also includes a blower arranged under the water receiving tray, a heating shell is arranged on one side of the blower through a bracket, heating rings distributed in a rectangular array are fixedly installed inside the heating shell, the exhaust end of the heating shell is fixedly connected to a Y-shaped ventilation pipe, and two branch pipe openings of the ventilation pipe are fixedly extended to the interior of the water-passing shell, and the discharge end of the air shower box is provided with symmetrically distributed electrostatic generators through the inner wall of the opening, and an electrostatic suction cup is installed on one side surface of the electrostatic generator through a support rod.

[0015] Through the above technical scheme, in order to improve the drying efficiency of the impregnated paper, air is sucked by a blower, filtered and then discharged into the interior of the heating shell. The air is preheated before being discharged through the heating shell, and multiple heating rings are synchronously operated to heat the air, so that the dry hot air enters the interior of the air shower box through the ventilation pipe, and then the circulating fan is operated to blow the hot air on the impregnated paper in a circulating manner, so that the impregnated paper is dried without damage. In order to remove impurities on the surface of the dried impregnated paper, the impregnated paper is passed through two electrostatic suction cups, so that the electrostatic generator is started, and the electrostatic suction cups are controlled to electrostatically adsorb impurities.

[0016] Preferably, the clamping mechanism includes a processing table arranged on one side of the air shower box, and the other guide roller is installed on the upper surface of the processing table. The upper surface of the processing table is symmetrically distributed and fixedly connected with a support frame, and the lower end of the support frame is rotatably connected with a resistance roller on the opposite side surface. The upper surface of the processing table is fixedly connected with a cutting roller, and the upper surface of the cutting roller is provided with a cutting groove.

[0017] Through the above technical scheme, in order to roll up the dried impregnated paper to a specified length, the impregnated paper coming out of the air shower box is guided by another guide roller and then pressed on the upper surface of the roller, so that the front end of the pressed part can be cut off conveniently. In order to cut the impregnated paper, a cutting knife can be arranged above the cutting roller. When the impregnated paper is rolled up to a suitable length, the cutting can be achieved by extending the cutting knife into the cutting groove.

[0018] Preferably, the clamping mechanism also includes a guide block slidably connected to the inner surface of the window of the support frame, the inner surfaces of the two guide blocks are rotatably connected with clamping rollers, the upper surface of the support frame is fixedly connected to a pulley housing through a support plate, the upper surface of the guide block is fixedly connected to a threaded sleeve, the outer surface of the threaded sleeve is movably connected to the inner surface of a hole penetrated through the upper surface of the support frame, the lower surfaces of both ends of the pulley housing are rotatably connected with adjusting screws, and the inner surface of the threaded sleeve is threadably connected to the outer surface of the adjusting screw.

[0019] Through the above technical scheme, in order to keep the impregnated paper taut and facilitate cutting and winding, when the impregnated paper is cut, the impregnated paper passes between the resistance roller and the clamping roller, and the impregnated paper stops being transported. A pulley assembly including a pulley, a transmission belt, and a driving motor is arranged inside the pulley housing, thereby driving the two adjusting screws to rotate synchronously, so that the threaded sleeve pushes the guide block downward, and the guide block drives the clamping roller to press on the surface of the impregnated paper, thereby maintaining the tension during cutting, and at the same time, the rear end of the cutting part remains tensioned.

[0020] Preferably, the winding mechanism includes a motor block fixedly mounted on the upper surface of the processing table through a support block, one side surface of the motor block is rotatably connected to a winding roller through a coupling, one side surface of the processing table is fixedly connected to support rings distributed up and down, the inner surface of the support ring is rotatably connected to a rotating rod, the outer surface of the rotating rod is fixedly connected to a linkage rod, one side surface of the linkage rod is fixedly connected to a ball bearing, and the inner surface of the inner ring of the ball bearing is slidably sleeved with the outer surface of the movable end of the winding roller.

[0021] Through the above technical scheme, in order to remove the impregnated paper rolled on the winding roller and facilitate the next winding, the rotating rod supported by the support ring is controlled to drive the linkage rod to rotate 90 degrees, so that the ball bearing sleeved on the active end of the winding roller is away from the winding roller, and then the rolled impregnated paper can be pulled off the winding roller manually or by a robot, and then the linkage rod drives the ball bearing to reset, so that the ball bearing is sleeved on the outer surface of the active end of the winding roller, and the winding roller is driven to rotate by the motor inside the motor block, thereby realizing continuous winding of the winding roller.

[0022] Preferably, the winding mechanism also includes a traction rod fixedly sleeved on the outer surface of the lower end of the rotating rod, and a pushing cylinder is hinged on one side surface of the processing table. The piston rod surface of the pushing cylinder is hinged to the outer surface of one end of the traction rod through a hinged ear plate.

[0023] Through the above technical solution, in order to push the linkage rod to drive the ball bearing to deflect and rotate, the hinged pushing cylinder is actuated to pull and push the traction rod, thereby driving the rotating rod to rotate.

[0024] Preferably, the winding mechanism also includes a support beam fixedly connected to the surface of one side of the motor block, a telescopic cylinder is fixedly connected to the upper surface of the support beam, and a piston rod of the telescopic cylinder extends to the lower surface of the support beam and is fixedly connected to a limiting ring.

[0025] Through the above technical scheme, in order to control the winding length, the limit ring is set above one end of the winding roller, so that the lower surface of the limit ring is in contact with the outer surface of the rolled impregnated paper, and as the winding increases, the telescopic cylinder continuously contracts the limit ring upward, but always keeps the impregnated paper and the contact surface of the limit ring in contact, thereby ensuring the neatness of the winding. At the same time, after the winding length is reached, the telescopic cylinder stops moving, so that the lower surface of the limit ring is pressed against the outer surface of the impregnated paper, thereby facilitating the cutting of its front end.

[0026] The present invention provides a cutting method of an impregnated paper impregnation drying cutting machine, comprising the following steps:

[0027] S1. The impregnated paper moving forward enters the impregnation tank filled with impregnation liquid under the guidance of the guide roller, and is impregnated on both sides in the tank with the assistance of the pressing roller, and then enters the air shower box through the feed hole after being guided by another guide roller at the end of the impregnation tank. Since the impregnated paper is suspended in the air, the impregnated paper can be drained. The drained water flows into the water receiving tray through the water passing shell, and flows from the surface of the rolling water slope to the water outlet pipe for discharge;

[0028] S2. When the impregnated paper is conveyed in the air shower box, multiple circulating fans are synchronously operated to blow circulating air to the inside of the air shower box. At the same time, the air is sucked by the blower and discharged into the inside of the heating shell after filtering. Before the air is discharged through the heating shell, multiple heating rings are synchronously operated to heat the air, so that the dry hot air enters the inside of the air shower box through the ventilation pipe, and then the circulating fan is operated to circulate the hot air to blow the impregnated paper, so that the impregnated paper is dried without damage.

[0029] S3, the impregnated paper coming out of the air shower box is guided by another guide roller and then pressed on the upper surface of the roller, and the other end of the impregnated paper is wound on the outer surface of the winding roller, and the ball bearing is sleeved on the outer surface of the movable end of the winding roller. The winding roller is driven to rotate by the motor inside the motor block, thereby realizing continuous winding of the winding roller;

[0030] S4. As the winding length increases, the telescopic cylinder continuously contracts the limit ring upward, but always keeps the contact surface of the impregnated paper and the limit ring in contact, thereby ensuring the neatness of the winding. At the same time, when the winding length is reached, the telescopic cylinder stops moving, so that the lower surface of the limit ring is pressed against the outer surface of the impregnated paper;

[0031] S5, at the same time, the impregnated paper stops conveying, and a pulley assembly including a pulley, a transmission belt, a driving motor, etc. is arranged inside the pulley housing, thereby driving the two adjusting screws to rotate synchronously, so that the threaded sleeve pushes the guide block downward, and the guide block drives the clamping roller to press on the surface of the impregnated paper, thereby maintaining the tension during cutting, and at the same time, the rear end of the cutting part is kept tensioned, and at this time, the cutting knife is inserted into the cutting groove to achieve cutting;

[0032] S6. After the impregnated paper is cut, the hinged pushing cylinder is activated to pull the traction rod, and then the rotating rod supported by the support ring can be controlled to drive the linkage rod to rotate 90 degrees, so that the ball bearing sleeved on the active end of the winding roller is away from the winding roller, and then the impregnated paper that has been rolled up can be pulled off the winding roller manually or by a robot, and then the linkage rod drives the ball bearing to reset, so that the ball bearing is sleeved on the outer surface of the active end of the winding roller. At this time, one end of the compressed impregnated paper is pulled to the outer surface of the winding roller by a robot or manually to achieve repeated winding and cutting.

[0033] The beneficial effects of the present invention are:

[0034] 1. By setting up an air-heating drying mechanism, the transported impregnated paper can be dried efficiently and gently. During the adjustment process, a conical water-passing shell is set up, and its inner wall is coated with a hydrophobic coating, so that the drained water can flow into the water receiving tray through the water-passing shell, and the air is sucked by the blower, and then discharged into the interior of the heating shell after filtering. The air is preheated before being discharged through the heating shell, and multiple heating rings are synchronously operated to heat the air, so that the dry hot air enters the interior of the air shower box through the ventilation pipe, and then the circulating fan is operated to circulate the hot air to blow the impregnated paper, so that the impregnated paper is dried without damage.

[0035] 2. By setting up a clamping mechanism, the impregnated paper can be kept tensioned when it is cut. During the adjustment process, the two adjusting screws are driven to rotate synchronously, so that the threaded sleeve pushes the guide block downward, and the guide block drives the clamping roller to press on the surface of the impregnated paper, thereby maintaining the tension during cutting, and at the same time, the rear end of the cutting part is kept tensioned.

[0036] 3. By setting up the winding mechanism, the impregnated paper can be flexibly taken out. During the adjustment process, the rotating rod supported by the control support ring drives the linkage rod to rotate 90 degrees, so that the ball bearing sleeved on the active end of the winding roller is away from the winding roller, and then the impregnated paper that has been rolled can be pulled away from the winding roller manually or by a robot, and then the linkage rod drives the ball bearing to reset, so that the ball bearing is sleeved on the outer surface of the active end of the winding roller, and the winding roller is driven to rotate by the motor inside the motor block, so that the continuous winding of the winding roller can be realized.

DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0051] Reference Figure 1-Figure 12A machine for impregnating, drying and cutting impregnated paper comprises a guide roller 1 for guiding the produced impregnated paper, an impregnation tank 2 is arranged between two groups of guide rollers 1, the inner surface of the impregnation tank 2 is rotatably connected to a pressing roller 3 through a bearing, an air-heating and drying mechanism 4 is arranged on one side of the impregnation tank 2, a clamping mechanism 6 is arranged at the conveying front end of the air-heating and drying mechanism 4, and a winding mechanism 8 is arranged at the conveying front end of the clamping mechanism 6.

[0052] The impregnated paper impregnated in the impregnation tank 2 passes through a pair of wind-heating and drying mechanisms 4, and the impregnated paper is dried by the uniform wind heating provided by the wind-heating and drying mechanisms 4.

[0053] The impregnated paper moving forward enters the impregnation tank 2 filled with impregnation liquid under the guidance of the guide roller 1, and is impregnated on both sides in the tank with the assistance of the pressing roller 3, and then enters the air-heating drying mechanism 4 from the end of the impregnation tank 2 through another guide roller 1 for drying. In order to dry the impregnated paper without damage, the air-heating drying mechanism 4 includes an air shower box 41 supported by support rods distributed in a rectangular array. A feed hole 42 is formed on the side surface of the air shower box 41 close to the adjacent guide roller 1, and the impregnated paper is fed from the feed hole 42. 42 enters the air shower box 41. Since the impregnated paper is suspended in the air, the impregnated paper can be drained. In order to prevent the drained water from accumulating in the air shower box 41 and causing a bad internal environment and making it inconvenient for the next impregnated paper to dry, a conical water-passing shell 43 is penetrated through the lower surface of the air shower box 41. The lower surface of the water-passing shell 43 is fixedly connected to a water receiving tray 44. The inner wall of the water-passing shell 43 is coated with a hydrophobic coating, so that the drained water can flow into the water receiving tray 44 through the water-passing shell 43.

[0054] In order to drain the water leaked from the impregnated paper as quickly as possible, the air-heating and drying mechanism 4 also includes a rolling water slope 45 fixedly connected to the inner bottom wall of the water receiving tray 44, and the bottom end of the rolling water slope 45 is fixedly connected to a water outlet pipe 46 with a water outlet valve. The impregnation water falling into the water receiving tray 44 flows from the surface of the rolling water slope 45 to the water outlet pipe 46 for discharge. In order to speed up the drying of the impregnated paper, circulating fans 47 are installed in a rectangular array on the upper surface of the air shower box 41. The multiple circulating fans 47 operate synchronously to blow circulating air to the interior of the air shower box 41.

[0055] In order to improve the drying efficiency of the impregnated paper, the air-heating drying mechanism 4 further includes a blower 48 arranged under the water receiving tray 44, a heating shell 49 is arranged on one side of the blower 48 through a bracket, heating rings 50 distributed in a rectangular array are fixedly installed inside the heating shell 49, and a Y-shaped ventilation pipe 51 is fixedly connected to the exhaust end of the heating shell 49, and two branch pipe openings of the ventilation pipe 51 are fixedly extended to the inside of the water passing shell 43, and air is sucked in by the blower 48 and discharged into the inside of the heating shell 49 after filtering, and the air is preheated before being discharged through the heating shell 49, and then the air is preheated by a plurality of heating rings. The ring 50 operates synchronously to heat the air, so that the dry hot air enters the interior of the air shower box 41 through the ventilation pipe 51, and then the circulating fan 47 operates to circulate the hot air to blow on the impregnated paper, so that the impregnated paper is dried without damage. In order to remove impurities on the surface of the dried impregnated paper, the discharge end of the air shower box 41 is equipped with symmetrically distributed electrostatic generators 52 through the inner wall of the opening, and an electrostatic suction cup 53 is installed on one side surface of the electrostatic generator 52 through a support rod. The impregnated paper passes through the two electrostatic suction cups 53, so that the electrostatic generator 52 is started, and the electrostatic suction cup 53 is controlled to electrostatically adsorb impurities.

[0056] By providing an air-heating drying mechanism 4, the transported impregnated paper can be dried efficiently and gently. During the adjustment process, a conical water-passing shell 43 is provided, and its inner wall is coated with a hydrophobic coating, so that the drained water can flow into the water receiving tray 44 through the water-passing shell 43, and the air is sucked by the blower 48, and then discharged into the interior of the heating shell 49 after filtering. Before the air is discharged through the heating shell 49, the air is preheated, and multiple heating rings 50 are synchronously operated to heat the air, so that the dry hot air enters the interior of the air shower box 41 through the ventilation pipe 51, and then the circulating fan 47 is operated to circulate the hot air to blow the impregnated paper, so that the impregnated paper is dried without damage.

[0057] The clamping mechanism 6 presses the cut surface of the impregnated paper so that the impregnated paper remains taut.

[0058] In order to roll up the dried impregnated paper to a specified length, the clamping mechanism 6 includes a processing table 61 arranged on one side of the air shower box 41, and another guide roller 1 is installed on the upper surface of the processing table 61. The upper surface of the processing table 61 is symmetrically distributed and fixedly connected with a support frame 62, and the lower end of the support frame 62 is rotatably connected with a resistance roller 63 on the opposite side surface. The impregnated paper coming out of the air shower box 41 is guided by another guide roller 1 and then pressed on the upper surface of the resistance roller 63, so that the front end of the pressed part can be cut off conveniently. In order to cut the impregnated paper, a cutting roller 64 is fixedly connected to the upper surface of the processing table 61, and a cutting groove 65 is opened on the upper surface of the cutting roller 64. A cutting knife can be arranged above the cutting roller 64. When the impregnated paper is rolled up to a suitable length, it can be cut by extending the cutting knife into the cutting groove 65.

[0059] In order to keep the impregnated paper taut and convenient for cutting and rewinding, the clamping mechanism 6 also includes a guide block 66 slidably connected to the inner surface of the window of the support frame 62, and the inner surfaces of the two guide blocks 66 are rotatably connected with clamping rollers 67. The upper surface of the support frame 62 is fixedly connected with a pulley housing 68 through a support plate, and the upper surface of the guide block 66 is fixedly connected with a threaded sleeve 69. The outer surface of the threaded sleeve 69 is movably connected to the inner surface of the perforated hole through the upper surface of the support frame 62, and the lower surfaces of both ends of the pulley housing 68 are rotatably connected with adjusting screws 7 0, the inner surface of the threaded sleeve 69 is threadedly sleeved with the outer surface of the adjusting screw 70. When the impregnated paper is cut, the impregnated paper passes between the roller 63 and the clamping roller 67. At this time, the impregnated paper stops being transported, and the pulley housing 68 is provided with a pulley assembly such as a pulley, a transmission belt, and a driving motor, thereby driving the two adjusting screws 70 to rotate synchronously, so that the threaded sleeve 69 pushes the guide block 66 downward, and the guide block 66 drives the clamping roller 67 to press on the surface of the impregnated paper, thereby maintaining the tension during cutting, and at the same time, the rear end of the cutting part is kept tensioned.

[0060] By providing the clamping mechanism 6, the impregnated paper can be kept tensioned when it is cut. During the adjustment process, the two adjusting screws 70 are driven to rotate synchronously, so that the threaded sleeve 69 pushes the guide block 66 downward, and the guide block 66 drives the clamping roller 67 to press on the surface of the impregnated paper, thereby maintaining the tension during cutting, and at the same time, the rear end of the cutting part is kept tensioned.

[0061] The winding mechanism 8 winds up the dried impregnated paper and opens one side of the winding shaft to take out the material.

[0062] In order to remove the impregnated paper rolled up on the winding roller 82 and facilitate the next winding, the winding mechanism 8 includes a motor block 81 fixedly mounted on the upper surface of the processing table 61 through a support block, and one side surface of the motor block 81 is rotatably connected to the winding roller 82 through a coupling, and one side surface of the processing table 61 is fixedly connected to a support ring 83 distributed up and down, and the inner surface of the support ring 83 is rotatably connected to a rotating rod 84, and the outer surface of the rotating rod 84 is fixedly connected to a linkage rod 85, and one side surface of the linkage rod 85 is fixedly connected to a ball bearing 86, and the inner surface of the inner ring of the ball bearing 86 is fixedly connected to the inner surface of the inner ring of the ball bearing 86. The rotating rod 84 supported by the control support ring 83 drives the linkage rod 85 to rotate 90 degrees, so that the ball bearing 86 sleeved on the movable end of the winding roller 82 is away from the winding roller 82, and then the rolled impregnated paper can be pulled away from the winding roller 82 manually or by a robot, and then the linkage rod 85 drives the ball bearing 86 to reset, so that the ball bearing 86 is sleeved on the outer surface of the movable end of the winding roller 82, and the winding roller 82 is driven to rotate by the motor inside the motor block 81, so that the continuous winding of the winding roller 82 can be realized.

[0063] In order to push the linkage rod 85 to drive the ball bearing 86 to deflect and rotate, the winding mechanism 8 also includes a traction rod 87 fixedly sleeved on the outer surface of the lower end of the rotating rod 84. A pushing cylinder 88 is hinged on the surface of one side of the processing table 61. The piston rod surface of the pushing cylinder 88 is hinged to the outer surface of one end of the traction rod 87 through a hinged ear plate. The hinged pushing cylinder 88 is actuated to pull and push the traction rod 87, thereby driving the rotating rod 84 to rotate.

[0064] In order to control the length of the winding, the winding mechanism 8 also includes a support beam 89 fixedly connected to the surface of one side of the motor block 81, and a telescopic cylinder 90 is fixedly connected to the upper surface of the support beam 89. The piston rod of the telescopic cylinder 90 extends to the lower surface of the support beam 89 and is fixedly connected to a limiting ring piece 91. The limiting ring piece 91 is arranged above one end of the winding roller 82, so that the lower surface of the limiting ring piece 91 is in contact with the outer surface of the wound impregnated paper, and as the winding increases, the telescopic cylinder 90 continuously contracts the limiting ring piece 91 upward, but always keeps the contact surface of the impregnated paper and the limiting ring piece 91 in contact, thereby ensuring the neatness of the winding, and at the same time, after reaching the winding length, the telescopic cylinder 90 stops moving, so that the lower surface of the limiting ring piece 91 is pressed against the outer surface of the impregnated paper, thereby facilitating the cutting of its front end.

[0065] By setting up the winding mechanism 8, the impregnated paper can be flexibly taken out. During the adjustment process, the rotating rod 84 supported by the control support ring 83 drives the linkage rod 85 to rotate 90 degrees, so that the ball bearing 86 sleeved on the movable end of the winding roller 82 is away from the winding roller 82, and then the impregnated paper that has been rolled up can be pulled away from the winding roller 82 manually or by a robot, and then the linkage rod 85 drives the ball bearing 86 to reset, so that the ball bearing 86 is sleeved on the outer surface of the movable end of the winding roller 82, and the winding roller 82 is driven to rotate by the motor inside the motor block 81, so that the continuous winding of the winding roller 82 can be achieved.

[0067] S1. The impregnated paper moving forward enters the impregnation tank 2 filled with impregnation liquid under the guidance of the guide roller 1, and is impregnated on both sides in the tank with the assistance of the pressing roller 3. Then, it is guided by another guide roller 1 from the end of the impregnation tank 2 and enters the air shower box 41 through the feed hole 42. Since the impregnated paper is suspended in the air, the impregnated paper can be drained. The drained water flows into the water receiving tray 44 through the water passing shell 43, and flows from the surface of the rolling water slope 45 to the water outlet pipe 46 for discharge;

[0068] S2. When the impregnated paper is conveyed in the air shower box 41, multiple circulating fans 47 are synchronously operated to blow circulating air to the inside of the air shower box 41. At the same time, air is sucked by the blower 48, filtered and discharged into the inside of the heating shell 49. Before the air is discharged through the heating shell 49, multiple heating rings 50 are synchronously operated to heat the air, so that dry hot air enters the inside of the air shower box 41 through the ventilation pipe 51. Then, the circulating fan 47 is operated to circulate the hot air to blow the impregnated paper, so that the impregnated paper is dried without damage.

[0069] S3, the impregnated paper coming out of the air shower box 41 is guided by another guide roller 1 and pressed on the upper surface of the roller 63, and the other end of the impregnated paper is wound on the outer surface of the winding roller 82, and the ball bearing 86 is sleeved on the outer surface of the movable end of the winding roller 82, and the winding roller 82 is driven to rotate by the motor inside the motor block 81, thereby realizing continuous winding of the winding roller 82;

[0070] S4. As the winding length increases, the telescopic cylinder 90 continuously contracts the limiting ring piece 91 upward, but always keeps the contact surface of the impregnated paper and the limiting ring piece 91 in contact, thereby ensuring the neatness of the winding. At the same time, when the winding length is reached, the telescopic cylinder 90 stops moving, so that the lower surface of the limiting ring piece 91 is pressed against the outer surface of the impregnated paper.

[0071] S5, at the same time, the impregnated paper stops conveying, and the pulley housing 68 is provided with a pulley assembly including a pulley, a transmission belt, and a driving motor, thereby driving the two adjusting screws 70 to rotate synchronously, so that the threaded sleeve 69 pushes the guide block 66 downward, and the guide block 66 drives the clamping roller 67 to press on the surface of the impregnated paper, thereby maintaining the tension during cutting, and at the same time, the rear end of the cutting part is kept tensioned, and at this time, the cutting knife is inserted into the cutting groove 65 to achieve cutting;

[0072] S6. After the impregnated paper is cut, the hinged pushing cylinder 88 is actuated to pull the traction rod 87, and then the rotating rod 84 supported by the support ring 83 can be controlled to drive the linkage rod 85 to rotate 90 degrees, so that the ball bearing 86 sleeved on the active end of the winding roller 82 is away from the winding roller 82, and then the rolled impregnated paper can be pulled away from the winding roller 82 manually or by a robot, and then the linkage rod 85 drives the ball bearing 86 to reset, so that the ball bearing 86 is sleeved on the outer surface of the active end of the winding roller 82. At this time, one end of the pressed impregnated paper is pulled to the outer surface of the winding roller 82 by a robot or manually to achieve repeated winding and cutting.
