Description

Technical Field

[0001] The present invention relates to the technical field of paper tube production, and particularly relates to a spandex paper tube winding paper production line and a production method thereof. Background Art

[0002] A paper tube is a tubular object processed from paper. Paper tubes have various uses in industry. Spandex is short for polyurethane fiber and is an elastic fiber. Spandex generally consists of multiple filaments, and the spandex filaments are wound and coated through a spandex paper tube.

[0003] Some patent documents in the technical field of paper winding mechanisms are disclosed in the prior art. The Chinese utility model with the application number CN201921909920.X discloses a paper winding mechanism for spandex paper tube production, including a base. A control box is fixedly installed on the left side of the top of the base. A paper winding roller and an electric telescopic rod are respectively movably installed on the right side and the left side of the top of the control box. A support column is fixedly installed on the right side of the base, and mounting plates are fixedly installed at both the upper and lower ends of the support column; for this paper winding mechanism for spandex paper tube production, both ends of the roller are connected through bearings and a first connecting rod. The top of the first connecting rod is movably sleeved with a fixed sleeve through a first spring, and a telescopic rod is installed at the top of the fixed sleeve. The connecting rod can move upward along the fixed sleeve.

[0004] In the prior art during the paper winding process, usually a long strip of paper for processing into a paper tube is wound around a shaft roller to form a paper tube. During the paper winding process, glue needs to be applied to the winding contact surface to make the wound paper tube stick tightly, and to improve the overall hardness of the paper tube after solidification. In the actual processing process, as the paper tube rotates and winds, the thickness of the paper tube gradually increases, and the distance between the glue application surface of the paper tube and the glue application device gradually increases, making it difficult to ensure the uniformity of glue application and affecting the processing effect of the paper tube. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a spandex paper tube winding paper production line and a production method thereof.

[0006] To achieve the above object, the technical solution adopted by the present invention is: a spandex paper tube winding paper production line, including a processing table. One end of the top of the processing table is fixedly connected with a first mounting plate. A transmission shaft is rotatably connected to the first mounting plate. One end of the transmission shaft is connected with a driving rotation mechanism. A second mounting plate is placed on one side of the first mounting plate. The second mounting plate is slidably connected to the top of the processing table. A hydraulic cylinder is fixedly installed on the top of the processing table. The piston rod of the hydraulic cylinder is fixedly connected to one side of the second mounting plate;

[0007] A paper winding roller is rotatably connected to the second mounting plate. A strip-shaped groove is formed on the surface of the paper winding roller. An arc-shaped strip is slidably connected inside the strip-shaped groove. A circular groove is formed at one end of the paper winding roller close to the transmission shaft. One end of the transmission shaft is located inside the circular groove. A limiting block is fixedly connected to the transmission shaft. A limiting groove is formed on the inner wall of the circular groove. The limiting block is located inside the limiting groove;

[0008] The other end of the top of the processing table is fixedly connected with a U-shaped frame. A paper strip clamping mechanism is connected to the U-shaped frame. An adhesive application box is placed between the U-shaped frame and the paper winding roller. A rotating adhesive application mechanism is connected to the top of the adhesive application box. A glue storage box is fixedly connected to the top of the processing table. A telescopic tube is fixedly connected and communicated between the adhesive application box and the glue storage box;

[0009] Mounting frames are placed on both sides of the glue application box. The mounting frames are fixedly connected to the top of the processing table. A synchronous movement mechanism is connected between the mounting frames and the glue application box. Through the action of the synchronous movement mechanism, when the thickness of the processed paper tube gradually increases, the position of the glue application box moves accordingly; during operation, in the prior art, during the process of winding paper, a long strip of paper used to process into a paper tube is usually wound around a shaft roller to form a paper tube. During the winding process, glue needs to be applied to the surface in contact with the winding to make the wound paper tube stick tightly, and to improve the overall hardness of the paper tube after solidification. In the actual processing process, as the paper tube rotates and winds, the thickness of the paper tube gradually increases, and the distance between the glue application surface of the paper tube and the glue application device gradually increases, making it difficult to ensure the uniformity of glue application and affecting the processing effect of the paper tube. This technical solution can solve the above problems. The specific working method is as follows: Apply adhesive on the surface of the arc-shaped strip. Pass one end of the strip of paper used for processing and winding through the inside of the U-shaped frame and elastically clamp it through the strip clamping mechanism. Then adhere one end of the strip of paper to the surface of the arc-shaped strip. Then drive the transmission shaft to rotate through the action of the drive rotation mechanism. The transmission shaft is located inside the circular groove. Through the limiting block located in the limiting groove, the transmission shaft drives the paper winding roller to rotate synchronously. The paper winding roller drives the arc-shaped strip to rotate, thereby driving the strip of paper to wind around the surface of the paper winding roller. During the winding process, the staff needs to first keep a distance between the strip of paper and the glue application box to avoid the first circle where the strip of paper contacts the paper winding roller from coming into contact with extra glue and preventing the formed paper tube from adhering to the paper winding roller. When the strip of paper has wound around the paper winding roller for one circle, the staff puts down the strip of paper to make one side of the moving and winding strip of paper contact the rotating glue application mechanism on the top of the glue application box. During the contact process, glue is applied to one side of the strip of paper to facilitate adhesion during the winding process. The glue in the glue storage box is replenished into the glue application box along the telescopic tube to keep the glue in the glue application box in a full state. As the number of winding turns of the paper tube being processed increases, the thickness increases. Through the action of the synchronous movement mechanism, the rotating glue application mechanism on the top of the glue application box moves accordingly as the thickness of the paper tube increases, so that the rotating glue application mechanism and one side of the moving strip of paper always remain in contact, ensuring the glue application effect and being beneficial to improving the paper winding processing effect of the paper tube. After the winding of the paper tube is completed, the piston rod of the hydraulic cylinder moves to drive the paper winding roller to move, so that the paper winding roller and the transmission shaft move away from each other. Then the paper tube is drawn out from one end of the paper winding roller. During the drawing process of the paper tube, the adhered arc-shaped strip is synchronously drawn out from one end of the strip-shaped groove, and then the arc-shaped strip is forcibly pulled out from the inner wall of the paper tube and placed back into the strip-shaped groove, completing the winding processing of the spandex paper roll.

[0010] Preferably, the driving and rotating mechanism includes a first motor and a first pulley. The first motor is fixedly installed on the top of the processing table. The first pulley is fixedly connected to one end of the transmission shaft. A second pulley is fixedly connected to the output shaft of the first motor. The first pulley and the second pulley are driven by a transmission belt; during operation, the output shaft of the first motor drives the second pulley to rotate, and through the driving action of the transmission belt, the first pulley rotates, thereby driving the transmission shaft to rotate on the first mounting plate and driving the paper winding roller to rotate for paper winding.

[0011] Preferably, the paper strip clamping mechanism includes two clamping rollers and two movable slots. The two movable slots are respectively opened on both sides of the U-shaped frame. Both clamping rollers are located inside the U-shaped frame. A connecting shaft is fixedly connected inside each clamping roller. Both ends of the connecting shaft extend out of the U-shaped frame from the adjacent movable slots and are fixedly connected with sliders. Rectangular frames are fixedly connected to both sides of the U-shaped frame. The sliders are all slidably connected inside the adjacent rectangular frames. A first limit pin is fixedly connected to the side of each adjacent pair of sliders facing away from each other. The first limit pins are all slidably inserted on the adjacent rectangular frames. A first spring is sleeved on each first limit pin. Both ends of the first spring are respectively fixedly connected to the adjacent slider and the inner wall of the rectangular frame; during operation, the two clamping rollers are toggled to move away from each other. The clamping rollers drive the internal connecting shafts to move along the movable slots, so that the two sliders in the rectangular frames slide away from each other. When the sliders slide away, they drive the first limit pins to move along the sliding insertion points and compress the first spring to produce a compressive deformation. Pass one end of the paper strip through between the two clamping rollers, and then release the external force on the clamping rollers. The elastic action causes the first spring to stretch outwards and squeeze the two sliders to move closer to each other, thereby driving the two connecting shafts to move closer to each other along the movable slots. The connecting shafts drive the clamping rollers to move. The two clamping rollers respectively clamp the two sides of the paper strip to clamp the paper strip. During the process of the paper strip passing through the paper winding roller and being wound into a paper tube, the two clamping rollers clamp the paper strip passing through the clamping rollers to keep the paper strip in a taut state during the winding process and improve the winding effect.

[0012] Preferably, the synchronous moving mechanism includes four connecting plates which are respectively and fixedly connected in pairs on both sides of the glue application box. A second limit pin is fixedly connected to the bottom of the connecting plate, and the second limit pins are all slidably inserted on the adjacent mounting frames. A second spring is sleeved on the second limit pin, and two ends of the second spring are respectively fixedly connected to the adjacent mounting frame and the bottom end of the second limit pin. Connecting curved rods are fixedly connected to both sides of the glue application box, and a contact roller is rotatably connected to one end of the connecting curved rod. The contact roller is located on the top of the paper winding roller. During operation, one end of the paper strip is passed between the paper winding roller and the contact roller and wound. Through the elastic action of the second spring, the contact roller is elastically pressed against the top of the paper tube on the surface of the paper winding roller. During the winding process, the contact roller rolls on one side of the paper tube. When the thickness of the paper tube gradually increases with winding, the contact roller gradually moves upward as the thickness of the paper tube increases, and drives the glue application box to move upward through the connecting curved rod. The connecting plates on both sides of the glue application box drive the second limit pins to move upward at the sliding insertion part of the mounting frame and compress the second spring, so that when the thickness of the paper tube increases, the distance between the rotating glue application mechanism on the glue application box and the paper sheet remains unchanged, thereby maintaining the stability of glue application.

[0013] Preferably, the rotating glue application mechanism includes two first rotating shafts which are both rotatably connected inside the glue application box. A plurality of glue rollers are fixedly connected to the first rotating shafts in a linear array, and the glue rollers on the two first rotating shafts are arranged staggeredly. A plurality of through slots are formed in the top of the glue application box, and the tops of the glue rollers extend above the glue application box from the adjacent through slots. During operation, when one end of the paper strip is wound on the paper winding roller, the paper strip moves towards the paper winding roller as the paper winding roller rotates. During the movement, the bottom surface of the paper strip contacts the glue rollers on the top of the glue application box, and drives the glue rollers to rotate through the moving contact. The glue rollers rotate around the first rotating shafts, and the arc surfaces of the glue rollers adhere to glue inside the glue application box. During the rotation, they rotate to the top of the glue application box through the through slots and apply the glue to the bottom surface of the paper strip, so that the bottom surface of the moving paper strip is continuously smeared with glue. By arranging the glue rollers on the two first rotating shafts staggeredly, no smearing gaps will occur on the bottom surface of the paper strip during movement, improving the smearing effect.

[0014] Preferably, two fixing plates are fixedly connected to one side of the glue application box. A second rotating shaft is rotatably connected between the fixing plates. An installation strip is fixedly connected to the rotating shaft. A plurality of cutting knives are fixedly installed on one side of the installation strip in a linear array. The positions of the plurality of cutting knives correspond to the glue rollers on one of the first rotating shafts. A second motor is fixedly installed on the fixing plate. The output shaft of the second motor is fixedly connected to one end of the second rotating shaft; during operation, after the paper strip is wound into a paper tube, the surface is a smooth arc surface. When winding the spandex, the spandex is likely to slide when winding on the surface of the paper tube, which is not conducive to the winding of the spandex. This technical solution can solve the above problems. The specific working method is as follows. When the paper strip is wound to the last few turns, the output shaft of the second motor rotates to drive the second rotating shaft to rotate 90 degrees between the two fixing plates, so that the installation strip rotates 90 degrees. The plurality of cutting knives at one end of the installation strip rotate to the upper side. The sharp section at one end of the cutting knife makes an opening on the paper strip, and a plurality of strip-shaped notches with the same distance are cut on the surface of the paper strip during the movement of the paper strip. After the cut paper strip is wound, the surface will present a plurality of annular grooves. When winding the spandex, the grooves on the surface of the paper tube limit the spandex to prevent the spandex from sliding during the winding process. The positions of the plurality of cutting knives correspond to the glue rollers on one of the first rotating shafts. During the cutting process, the generated strip-shaped grooves can pass through the top of the glue roller on the other first rotating shaft, avoiding applying glue between the strip-shaped grooves and preventing waste of glue.

[0015] Preferably, a collection box is fixedly connected to the bottoms of the two fixing plates. A connecting hose is fixedly connected to the bottom of the collection box. One end of the connecting hose is fixedly connected to a blower. The blower is fixedly installed on the top of the processing table. A grille is fixedly connected to the connection between the collection box and the connecting hose. An air inlet is opened on the top of the collection box. The installation strip is located above the air inlet; during operation, when the installation strip rotates 90 degrees along with the rotating shaft, one side of the installation strip contacts the inner wall of the collection box and opens the air inlet. The blower makes air enter the collection box through the connecting hose, so that negative pressure is generated inside the collection box. The slender strips cut by the cutting knives move into the collection box through the air inlet, preventing the cut slender strips from affecting the winding and the movement of the paper strip. A grille is fixedly connected to the connection between the collection box and the connecting hose to prevent the cut slender strips from entering the blower along the connecting hose and damaging the blower.

[0016] Preferably, the collecting box is internally rotatably connected to two third rotating shafts, each of which is fixedly connected to a cutting roller, and the cutting roller is fixedly connected to a spiral blade, and a third motor is fixedly installed on one side of the collecting box, and the output shaft of the third motor is fixedly connected to one end of one of the third rotating shafts, and the other ends of the two third rotating shafts pass through the collecting box and extend to the outside of the collecting box and are fixedly connected to gears, and the two gears are meshed with each other; when working, one of the third rotating shafts is driven to rotate by the output shaft of the third motor, and the two third rotating shafts are rotated in opposite directions under the meshing action of the two gears, and the slender strips inside the collecting box pass through the two cutting rollers, and are cut by the spiral blades on the cutting rollers by rotating in opposite directions, so as to prevent the slender strips from bending and stacking inside the collecting box, thereby improving the collection efficiency inside the collecting box.

[0017] Preferably, the two fixed plates are rotatably connected to a support roller at one end close to the U-shaped frame, and the top of the support roller is flush with the top of the paper winding roller; during operation, the bottom surface of the paper strip is supported by the support roller, and when the thickness of the paper tube gradually increases with winding and the glue coating box moves upward, the paper strip bends at the top of the support roller as the glue coating box moves upward, and the arc surface of the support roller is used to reduce the pressure at the bending point of the paper strip to prevent the paper strip from being scratched when moving at the bending point.

[0018] A production method for a spandex paper tube winding production line, the method comprising the following steps:

[0019] Step 1: Apply glue on the surface of the curved noodle, pass one end of the paper strip for processing and winding through the inside of the U-shaped frame, and elastically clamp it through the paper strip clamping mechanism, and then adhere one end of the paper strip to the surface of the curved noodle, and drive the transmission shaft to rotate through the action of the driving rotating mechanism, and the transmission shaft drives the paper winding roller to rotate synchronously, and the paper winding roller drives the curved noodle to rotate, thereby driving the paper strip to be wound on the surface of the paper winding roller;

[0020] Step 2: Keep a distance between the paper strip and the glue coating box. When the paper strip has been wound around the paper winding roller for one circle, the staff puts down the paper strip so that one side of the moving wound paper strip contacts the rotating glue coating mechanism on the top of the glue coating box. During the contact process, glue is applied to one side of the paper strip through the rotating glue coating mechanism to facilitate adhesion during the winding process. The thickness of the paper tube in processing increases with the increase in the number of winding circles. Through the action of the synchronous moving mechanism, the rotating glue coating mechanism on the top of the glue coating box moves accordingly with the increase in the thickness of the paper tube, so that the rotating glue coating mechanism and one side of the moving paper strip always keep in contact;

[0021] Step 3: After the winding of the paper tube is completed, the piston shaft of the hydraulic cylinder moves to drive the paper winding roller to move, so that the paper winding roller and the transmission shaft move away from each other. Then, the paper tube is drawn out from one end of the paper winding roller. During the drawing process of the paper tube, the adhered arc-shaped strip is synchronously taken out from one end of the strip groove, and then the arc-shaped strip is forcibly pulled out from the inner wall of the paper tube and placed back into the strip groove, completing the winding process of the spandex paper roll.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The glue storage box replenishes glue into the glue application box along the telescopic tube, keeping the glue in the glue application box in a full state. As the number of winding turns of the paper tube during processing increases, the thickness of the paper tube increases. Through the action of the synchronous movement mechanism, the rotating glue application mechanism on the top of the glue application box moves accordingly as the thickness of the paper tube increases, so that the rotating glue application mechanism and one side of the moving paper strip always remain in contact, ensuring the glue application effect and being beneficial to improving the paper winding processing effect of the paper tube.

[0024] 2. One end of the paper strip is passed between the paper winding roller and the contact roller and wound. Through the elastic action of the second spring, the contact roller is elastically pressed against the top of the paper tube on the surface of the paper winding roller. During the winding process, the contact roller rolls on one side of the paper tube. When the thickness of the paper tube gradually increases with winding, the contact roller gradually moves upward as the thickness of the paper tube increases, and drives the glue application box to move upward through the connecting curved rod. The connecting plates on both sides of the glue application box drive the second limit pin to move upward at the sliding insertion part of the mounting frame and compress the second spring, so that when the thickness of the paper tube increases, the distance between the rotating glue application mechanism on the glue application box and the paper strip always remains unchanged, thus maintaining the stability of glue application.

[0025] 3. The glue roller is rotated by moving contact. The glue roller rotates around the first rotating shaft. The arc surface of the glue roller adheres to glue inside the glue application box. During rotation, it rotates to the upper part of the glue application box through the through groove and applies the glue to the bottom surface of the paper strip, so that the bottom surface of the moving paper strip is continuously smeared with glue. By arranging the glue rollers on the two first rotating shafts in a staggered manner, no smearing gap will occur during the movement of the bottom surface of the paper strip, improving the smearing effect.

[0026] 4. Multiple cutting knives at one end of the installation strip rotate upwards, and the sharp segments at one end of the cutting knives make openings on the paper strip, and multiple strip-shaped notches with the same distance are cut on the surface of the paper strip during the movement of the paper strip. After the paper strip is cut into strips and wound, multiple annular grooves will appear on the surface. When winding the spandex, the grooves on the surface of the paper tube limit the spandex, preventing the spandex from sliding during the winding process. The positions of the multiple cutting knives correspond to the glue rollers on one of the first rotating shafts. During the process of cutting the strips, the generated strip-shaped grooves can pass through the tops of the glue rollers on the other first rotating shaft, avoiding gluing between the strip-shaped grooves and preventing waste of the glue.

[0027] 5. When the installation strip rotates 90 degrees along with the rotating shaft, one side of the installation strip contacts the inner wall of the collection box, and the air inlet is opened. Through the action of the connecting hose, the fan makes the air inlet blow air into the collection box, so that negative pressure is generated inside the collection box. The slender strips cut by the cutting knives move into the collection box through the air inlet, preventing the cut slender strips from affecting the winding and the movement of the paper strip. A grille is fixedly connected at the connection between the collection box and the connecting hose to prevent the cut slender strips from entering the fan along the connecting hose and damaging the fan.

Detailed implementation manners

[0040] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0041] As Figures 1 to 11 shown, a spandex paper tube winding production line includes a processing table 1. One end of the top of the processing table 1 is fixedly connected with a first mounting plate 2. A transmission shaft 3 is rotatably connected to the first mounting plate 2. One end of the transmission shaft 3 is connected with a driving rotation mechanism. A second mounting plate 4 is placed on one side of the first mounting plate 2. The second mounting plate 4 is slidably connected to the top of the processing table 1. A hydraulic cylinder 5 is fixedly installed on the top of the processing table 1. The piston rod of the hydraulic cylinder 5 is fixedly connected to one side of the second mounting plate 4;

[0042] A paper winding roller 6 is rotatably connected to the second mounting plate 4. A strip groove 7 is formed on the surface of the paper winding roller 6. An arc-shaped strip 8 is slidably connected inside the strip groove 7. A circular groove 9 is formed at one end of the paper winding roller 6 close to the transmission shaft 3. One end of the transmission shaft 3 is located inside the circular groove 9. A limiting block 10 is fixedly connected to the transmission shaft 3. A limiting groove 11 is formed on the inner wall of the circular groove 9. The limiting block 10 is located inside the limiting groove 11;

[0043] At the other end of the top of the processing table 1, a U-shaped frame 12 is fixedly connected. A paper strip clamping mechanism is connected to the U-shaped frame 12. A glue application box 13 is placed between the U-shaped frame 12 and the paper winding roller 6. A rotating glue application mechanism is connected to the top of the glue application box 13. A glue storage box 14 is fixedly connected to the top of the processing table 1. A telescopic tube 15 is fixedly connected and communicated between the glue application box 13 and the glue storage box 14;

[0044] Mounting brackets 16 are placed on both sides of the glue - applying box 13. The mounting brackets 16 are fixedly connected to the top of the processing table 1. A synchronous moving mechanism is connected between the mounting brackets 16 and the glue - applying box 13. Through the action of the synchronous moving mechanism, when the thickness of the processed paper tube gradually increases, the position of the glue - applying box 13 moves accordingly. During operation, in the prior art, during the process of winding paper, a long strip of paper used for processing into a paper tube is usually wound around a shaft roller to form a paper tube. During the winding process, glue needs to be applied to the surface in contact with the winding to make the wound paper tube stick tightly. After solidification, the overall hardness of the paper tube is improved. In the actual processing process, as the paper tube rotates and winds, the thickness of the paper tube gradually increases, and the distance between the glue - applying surface of the paper tube and the glue - applying device gradually increases, making it difficult to ensure the uniformity of glue application and affecting the processing effect of the paper tube. This technical solution can solve the above problems. The specific working method is as follows: Apply adhesive on the surface of the arc - shaped strip 8. Pass one end of the strip of paper for processing and winding through the inside of the U - shaped frame 12, and elastically clamp it through the strip - paper clamping mechanism. Then, adhere one end of the strip of paper to the surface of the arc - shaped strip 8. Then, drive the transmission shaft 3 to rotate through the action of the driving and rotating mechanism. The transmission shaft 3 is located inside the circular groove 9. Through the limit block 10 located in the limit groove 11, the transmission shaft 3 drives the paper - winding roller 6 to rotate synchronously. The paper - winding roller 6 drives the arc - shaped strip 8 to rotate, thereby driving the strip of paper to wind around the surface of the paper - winding roller 6. During the winding process, the staff needs to keep a distance between the strip of paper and the glue - applying box 13 first to avoid the first circle where the strip of paper contacts the paper - winding roller 6 from coming into contact with extra glue and prevent the formed paper tube from adhering to the paper - winding roller 6. When the strip of paper has wound one circle on the paper - winding roller 6, the staff puts down the strip of paper, so that one side of the moving and winding strip of paper contacts the rotating glue - applying mechanism on the top of the glue - applying box 13. During the contact process, glue is applied to one side of the strip of paper to facilitate adhesion during the winding process. The glue in the glue - applying box 13 is replenished through the glue storage box 14 along the telescopic tube 15 to keep the glue in the glue - applying box 13 in a full state. As the thickness of the paper tube being processed increases with the number of winding turns, through the action of the synchronous moving mechanism, the rotating glue - applying mechanism on the top of the glue - applying box 13 moves accordingly as the thickness of the paper tube increases, so that the rotating glue - applying mechanism and one side of the moving strip of paper always remain in contact, ensuring the glue - applying effect and being beneficial to improving the paper - winding processing effect of the paper tube. After the winding of the paper tube is completed, the piston shaft of the hydraulic cylinder 5 moves to drive the paper - winding roller 6 to move, so that the paper - winding roller 6 and the transmission shaft 3 move away from each other. Then, the paper tube is pulled out from one end of the paper - winding roller 6. During the pulling - out process of the paper tube, the adhered arc - shaped strip 8 is synchronously pulled out from one end of the strip - shaped groove 7, and then the arc - shaped strip 8 is forcibly pulled out from the inner wall of the paper tube and put back into the strip - shaped groove 7 again to complete the winding processing of the spandex paper roll.

[0045] As a further embodiment of the present invention, the driving and rotating mechanism includes a first motor 17 and a first pulley 18. The first motor 17 is fixedly installed on the top of the processing table 1. The first pulley 18 is fixedly connected to one end of the transmission shaft 3. A second pulley 19 is fixedly connected to the output shaft of the first motor 17. The first pulley 18 and the second pulley 19 are driven by a transmission belt 20. During operation, the output shaft of the first motor 17 drives the second pulley 19 to rotate, and through the transmission of the transmission belt 20, the first pulley 18 rotates, thereby driving the transmission shaft 3 to rotate on the first mounting plate 2 and driving the paper winding roller 6 to rotate for paper winding.

[0046] As a further embodiment of the present invention, the paper strip clamping mechanism includes two clamping rollers 21 and two movable slots 22. The two movable slots 22 are respectively opened on both sides of the U-shaped frame 12. The two clamping rollers 21 are both located inside the U-shaped frame 12. A connecting shaft 23 is fixedly connected to the inside of each clamping roller 21. Both ends of the connecting shaft 23 extend from the adjacent movable slots 22 to the outside of the U-shaped frame 12 and are fixedly connected to a slider 24. A rectangular frame 25 is fixedly connected to both sides of the U-shaped frame 12. The sliders 24 are both slidably connected to the inside of the adjacent rectangular frame 25. A first limit pin 26 is fixedly connected to the opposite side of the adjacent two sliders 24. The first limit pins 26 are both slidably inserted on the adjacent rectangular frame 25. A first spring 27 is sleeved on each first limit pin 26. Both ends of the first spring 27 are respectively fixedly connected to the adjacent slider 24 and the inner wall of the rectangular frame 25. During operation, the two clamping rollers 21 are toggled to move away from each other. The clamping rollers 21 drive the internal connecting shaft 23 to move along the movable slot 22, so that the two sliders 24 in the rectangular frame 25 slide away from each other. When the sliders 24 slide away, they drive the first limit pins 26 to move along the sliding insertion position and compress the first spring 27 to generate a compressive deformation. One end of the paper strip is passed through between the two clamping rollers 21, and then the external force on the clamping rollers 21 is removed. The elastic action causes the first spring 27 to extend outwards and squeeze the two sliders 24 to approach each other, thereby driving the two connecting shafts 23 to approach each other along the movable slot 22. The connecting shafts 23 drive the clamping rollers 21 to move, and the two clamping rollers 21 respectively clamp the two sides of the paper strip to clamp the paper strip. During the process of the paper strip passing through the paper winding roller 6 and being wound into a paper tube, the two clamping rollers 21 clamp the paper strip passing through the clamping rollers 21, so that the paper strip remains in a taut state during the winding process, improving the winding effect.

[0047] As a further embodiment of the present invention, the synchronous moving mechanism includes four connecting plates 28. The connecting plates 28 are respectively and fixedly connected in pairs on both sides of the glue application box 13. A second limit pin 29 is fixedly connected to the bottom of the connecting plate 28. The second limit pins 29 are all slidably inserted on the adjacent mounting frames 16. A second spring 30 is sleeved on the second limit pin 29. The two ends of the second spring 30 are respectively fixedly connected to the adjacent mounting frame 16 and the bottom end of the second limit pin 29. Connecting curved rods 31 are fixedly connected to both sides of the glue application box 13. A contact roller 32 is rotatably connected to one end of the connecting curved rod 31. The contact roller 32 is located on the top of the paper winding roller 6. During operation, one end of the paper strip is passed between the paper winding roller 6 and the contact roller 32 and wound. Through the elastic action of the second spring 30, the contact roller 32 is elastically pressed against the top of the paper tube on the surface of the paper winding roller 6. During the winding process, the contact roller 32 rolls on one side of the paper tube. When the thickness of the paper tube gradually increases with winding, the contact roller 32 gradually moves upward as the thickness of the paper tube increases, and drives the glue application box 13 to move upward through the connecting curved rod 31. The connecting plates 28 on both sides of the glue application box 13 drive the second limit pins 29 to move upward at the sliding insertion part of the mounting frame 16 and compress the second spring 30, so that when the thickness of the paper tube increases, the distance between the rotating glue application mechanism on the glue application box 13 and the paper sheet remains unchanged, thereby maintaining the stability of glue application.

[0048] As a further embodiment of the present invention, the rotating glue application mechanism includes two first rotating shafts 33. The two first rotating shafts 33 are both rotatably connected inside the glue application box 13. A plurality of glue rollers 34 are fixedly connected to the first rotating shafts 33 in a linear array. The glue rollers 34 on the two first rotating shafts 33 are arranged in a staggered manner. A plurality of through slots 35 are opened at the top of the glue application box 13. The top of the glue roller 34 extends from the adjacent through slot 35 above the glue application box 13. During operation, when one end of the paper strip is wound on the paper winding roller 6, the paper strip moves in the direction of the paper winding roller 6 as the paper winding roller 6 rotates. During the moving process, the bottom surface of the paper strip contacts the glue roller 34 on the top of the glue application box 13, and drives the glue roller 34 to rotate through the moving contact. The glue roller 34 rotates around the first rotating shaft 33. The arc surface of the glue roller 34 adheres to glue inside the glue application box 13, and rotates to the upper part of the glue application box 13 through the through slot 35 during the rotation process, and applies the glue to the bottom surface of the paper strip, so that the bottom surface of the moving paper strip is continuously smeared with glue. By arranging the glue rollers 34 on the two first rotating shafts 33 in a staggered manner, no smearing gap will be generated during the movement of the bottom surface of the paper strip, improving the smearing effect.

[0049] As a further embodiment of the present invention, two fixing plates 36 are fixedly connected to one side of the glue applicator box 13. A second rotating shaft 37 is rotatably connected between the fixing plates 36. An installation strip 38 is fixedly connected to the rotating shaft. A plurality of cutting knives 39 are fixedly installed on one side of the installation strip 38 in a linear array. The positions of the plurality of cutting knives 39 correspond to the position of the glue roller 34 on one of the first rotating shafts 33. A second motor 40 is fixedly installed on the fixing plate 36. The output shaft of the second motor 40 is fixedly connected to one end of the second rotating shaft 37. When working, after the paper strip is wound into a paper tube, the surface is a smooth arc surface. When winding the spandex, the spandex is likely to slide when winding on the surface of the paper tube, which is not conducive to the winding of the spandex. This technical solution can solve the above problems. The specific working method is as follows. When the paper strip is wound to the last few turns, the output shaft of the second motor 40 rotates, driving the second rotating shaft 37 to rotate 90 degrees between the two fixing plates 36, so that the installation strip 38 rotates 90 degrees. The plurality of cutting knives 39 at one end of the installation strip 38 rotate to the upper side. The sharp section at one end of the cutting knife 39 makes an opening on the paper strip, and a plurality of strip-shaped grooves 7 with the same distance are cut on the surface of the paper strip during the movement of the paper strip. After the cut paper strip is wound, the surface will present a plurality of annular grooves. When winding the spandex, the spandex is limited by the grooves on the surface of the paper tube to prevent the spandex from sliding during the winding process. The positions of the plurality of cutting knives 39 correspond to the position of the glue roller 34 on one of the first rotating shafts 33. During the cutting process, the generated strip-shaped grooves can pass through the top of the glue roller 34 on the other first rotating shaft 33, avoiding applying glue between the strip-shaped grooves and preventing waste of glue.

[0050] As a further embodiment of the present invention, a collection box 41 is fixedly connected to the bottom of the two fixing plates 36. A communication hose 42 is fixedly connected to the bottom of the collection box 41. One end of the communication hose 42 is fixedly connected to a blower 43. The blower 43 is fixedly installed on the top of the processing table 1. A grille 44 is fixedly connected to the connection between the collection box 41 and the communication hose 42. An air inlet 45 is opened on the top of the collection box 41. The installation strip 38 is located above the air inlet 45. When working, after the installation strip 38 rotates 90 degrees along with the rotating shaft, one side of the installation strip 38 contacts the inner wall of the collection box 41 and opens the air inlet 45. The blower 43, through the action of the communication hose 42, makes the air inlet 45 intake air into the collection box 41, so that a negative pressure is generated inside the collection box 41. The slender strips cut by the cutting knives 39 move into the collection box 41 through the air inlet 45, preventing the cut slender strips from affecting the winding and the movement of the paper strip. A grille 44 is fixedly connected to the connection between the collection box 41 and the communication hose 42 to prevent the cut slender strips from entering the blower 43 along the communication hose 42 and damaging the blower 43.

[0051] As a further embodiment of the present invention, two third rotating shafts 46 are rotatably connected inside the collection box 41. Cutting rollers 47 are fixedly connected to the third rotating shafts 46. Spiral blades 48 are fixedly connected to the cutting rollers 47. A third motor 49 is fixedly installed on one side of the collection box 41. The output shaft of the third motor 49 is fixedly connected to one end of one of the third rotating shafts 46. The other ends of the two third rotating shafts 46 penetrate through the collection box 41 and extend to the outside of the collection box 41 and are fixedly connected with gears 50. The two gears 50 are meshed with each other. During operation, the output shaft of the third motor 49 drives one of the third rotating shafts 46 to rotate. Under the meshing action of the two gears 50, the two third rotating shafts 46 rotate towards each other. When the slender strips inside the collection box 41 pass through the two cutting rollers 47, they are cut by the spiral blades 48 on the cutting rollers 47 rotating towards each other, preventing the slender strips from bending and stacking inside the collection box 41 and improving the collection efficiency inside the collection box 41.

[0052] As a further embodiment of the present invention, support rollers 51 are rotatably connected to one ends of the two fixing plates 36 close to the U-shaped frame 12. The top ends of the support rollers 51 are flush with the top ends of the paper winding rollers 6. During operation, the bottom surface of the paper strip is supported by the support rollers 51. When the thickness of the paper tube gradually increases with winding, when the glue application box 13 moves upward, the paper strip moves upward with the glue application box 13 and bends on the top of the support rollers 51. The arc surface of the support rollers 51 is used to reduce the pressure at the bending part of the paper strip and prevent the paper strip from being scratched when moving at the bending part.

[0053] A production method for an ammonia fiber paper tube winding production line, the method comprising the following steps:

[0054] Step 1: Apply adhesive on the surface of the arc-shaped strip 8. Pass one end of the paper strip for processing and winding through the inside of the U-shaped frame 12, and elastically clamp it through the paper strip clamping mechanism. Then adhere one end of the paper strip to the surface of the arc-shaped strip 8. Drive the transmission shaft 3 to rotate through the action of the driving rotation mechanism. The transmission shaft 3 drives the paper winding roller 6 to rotate synchronously. The paper winding roller 6 drives the arc-shaped strip 8 to rotate, thereby driving the paper strip to wind on the surface of the paper winding roller 6.

[0055] Step 2: First, keep a distance between the paper strip and the glue application box 13. After the paper strip has wound one circle on the paper winding roller 6, the staff puts down the paper strip, so that one side of the moving and winding paper strip contacts the rotating glue application mechanism on the top of the glue application box 13. During the contact process, the rotating glue application mechanism applies glue on one side of the paper strip to facilitate adhesion during the winding process. The thickness of the paper tube being processed increases as the number of winding turns increases. Through the action of the synchronous movement mechanism, the rotating glue application mechanism on the top of the glue application box 13 moves correspondingly as the thickness of the paper tube increases, so that the rotating glue application mechanism and one side of the moving paper strip always remain in contact.

[0056] Step 3: After the winding of the paper tube is completed, the piston shaft of the hydraulic cylinder 5 moves to drive the paper winding roller 6 to move, so that the paper winding roller 6 and the transmission shaft 3 move away from each other. Then, the paper tube is drawn out from one end of the paper winding roller 6. During the drawing process of the paper tube, the adhered arc-shaped strip 8 is synchronously drawn out from one end of the strip groove 7. Then, the arc-shaped strip 8 is forcibly pulled out from the inner wall of the paper tube and placed back into the strip groove 7, completing the winding process of the spandex paper roll.

[0057] The working principle of the present invention:

[0058] Apply glue on the surface of the arc-shaped strip 8. Pass one end of the paper strip for winding processing through the inside of the U-shaped frame 12 and elastically clamp it through the paper strip clamping mechanism. Then, adhere one end of the paper strip to the surface of the arc-shaped strip 8. Then, drive the transmission shaft 3 to rotate through the action of the driving rotation mechanism. The transmission shaft 3 is located inside the circular groove 9 and is positioned in the limit groove 11 by the limit block 10, so that the transmission shaft 3 drives the paper winding roller 6 to rotate synchronously. The paper winding roller 6 drives the arc-shaped strip 8 to rotate, thereby driving the paper strip to wind around the surface of the paper winding roller 6. During the winding process, the staff needs to keep a distance between the paper strip and the glue application box 13 first to avoid the paper strip contacting additional glue on the first circle in contact with the paper winding roller 6 and prevent the formed paper tube from adhering to the paper winding roller 6. When the paper strip has wound one circle on the paper winding roller 6, the staff puts down the paper strip to make one side of the moving and winding paper strip contact the rotating glue application mechanism on the top of the glue application box 13. During the contact process, glue is applied to one side of the paper strip to facilitate adhesion during the winding process. The glue in the glue application box 13 is replenished through the glue storage box 14 along the telescopic tube 15 to keep the glue in the glue application box 13 in a full state. The thickness of the processed paper tube increases as the number of winding turns increases. Through the action of the synchronous movement mechanism, the rotating glue application mechanism on the top of the glue application box 13 moves accordingly as the thickness of the paper tube increases, so that the rotating glue application mechanism and one side of the moving paper strip always remain in contact, ensuring the glue application effect and being beneficial to improving the paper winding processing effect of the paper tube. After the winding of the paper tube is completed, the piston shaft of the hydraulic cylinder 5 moves to drive the paper winding roller 6 to move, so that the paper winding roller 6 and the transmission shaft 3 move away from each other. Then, the paper tube is drawn out from one end of the paper winding roller 6. During the drawing process of the paper tube, the adhered arc-shaped strip 8 is synchronously drawn out from one end of the strip groove 7. Then, the arc-shaped strip 8 is forcibly pulled out from the inner wall of the paper tube and placed back into the strip groove 7, completing the winding process of the spandex paper roll.
