Description

Technical Field

[0001] This utility model relates to the field of paper production technology, specifically to a ceramic wrinkling doctor blade assembly for paper production. Background Technology

[0002] In the production process of toilet paper, the function of the creping doctor blade is to scrape the toilet paper that is attached to the surface of the drying cylinder and complete the creping by utilizing the speed difference between the roll cylinder and the drying cylinder. The creping doctor blade has an important impact on the quality of toilet paper, including the physical properties such as the tensile strength, fullness, and fineness of the creases, as well as the appearance.

[0003] For example, a ceramic creping doctor blade assembly for paper production, with announcement number "CN110424177A," extends the online operating time of the ceramic creping doctor blade and reduces the frequency of replacement by incorporating a grinding component, thereby saving labor costs associated with replacement and improving production efficiency. The electric cylinder increases the grinding frequency of the ceramic creping doctor blade, further extending its service life. However, this ceramic creping doctor blade assembly cannot operate while grinding the ceramic creping doctor blade; processing can only continue after grinding is complete, thus reducing production efficiency. Furthermore, this assembly cannot oscillate during paper creping; the creping doctor blade needs to oscillate continuously to maintain intermittent contact with the paper, preventing the creases from being constantly in contact with the paper and achieving the desired creping effect. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the ceramic creping doctor blade assembly used in paper production, which cannot work when the ceramic creping doctor blade is being polished, and can only continue processing after polishing is completed, thus reducing production efficiency. At the same time, the ceramic creping doctor blade assembly used in paper production cannot swing during the paper creping process, and the creping doctor blade needs to swing continuously to keep the doctor blade in intermittent contact with the paper, so that the paper folds are always in contact with the paper and cannot achieve the purpose of creping. Therefore, a ceramic creping doctor blade assembly for paper production is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a ceramic creping doctor blade assembly for paper production, including a base plate, a circular roller mounted on the upper left side of the base plate, a first outer shell fixedly connected to the center of the base plate, a rotating mechanism inside the first outer shell, two second outer shells on one side of the rotating mechanism, a swinging mechanism inside the second outer shell, a clamping plate on the outer wall of the swinging mechanism, and a creping doctor blade mounted on the inner wall of the clamping plate by bolts, the bottom of the second outer shell being fixedly connected to another second outer shell, and a cylinder fixedly connected to the right side of the base plate.

[0007] Preferably, a support plate is fixedly connected to the output end of the cylinder, a first motor is fixedly connected to the outer wall of the support plate, a grinding roller is fixedly connected to the output end of the first motor, and the rotating shaft of the grinding roller is rotatably connected to the support plate through a bearing.

[0008] Preferably, the rotating mechanism includes a second motor, the output shaft of the second motor is fixedly connected to a worm gear, the outer wall of the worm gear meshes with a worm wheel, the rotating shaft of the worm wheel is fixedly connected to a limit rod, the outer wall of the limit rod is in contact with a left limit plate, and the rotating shaft of the worm wheel is rotatably connected to the first outer shell through a bearing.

[0009] Preferably, the limiting plate is symmetrically fixed on both sides of the first housing, the outer wall of the second motor is fixedly connected to the first housing, and the rotation shaft of the worm gear is fixedly connected to the center point of the two first housings.

[0010] Preferably, the swing mechanism includes a third motor, the output shaft of the third motor is fixedly connected to a rotating rod, the inner wall of the rotating rod is slidably connected to a connecting rod, the end of the connecting rod is fixedly connected to a disc, the rotating shaft of the disc is rotatably connected to a rotating block through a bearing, and the two outer walls of the rotating block are rotatably connected to a second outer shell through pins.

[0011] Preferably, the outer walls of the rotating blocks are all fixedly connected to clamping plates, and the outer wall of the third motor is fixedly connected to the second outer shell.

[0012] The ceramic creping blade assembly for paper production proposed in this utility model has the following advantages: Through the cooperation of the rotating mechanism and the grinding roller, the output shaft of the second motor rotates forward, driving the worm gear to rotate, which in turn drives the worm wheel to rotate. The rotation of the worm wheel drives the limit rod to rotate and the two first housings to rotate. The rotation of the first housings drives the swing mechanism to rotate, which in turn drives the creping blade to rotate. When the limit rod is in contact with the limit plate on the right, the second motor stops. At this time, the worm wheel rotates exactly 180 degrees. The 180-degree rotation of the worm wheel allows the upper and lower creping blades to exchange positions, saving working time. While grinding the creping blade, paper processing can continue, saving waiting time for grinding and thus improving work efficiency.

[0013] Through the cooperation of the swing mechanism and the crease scraper, the output shaft of the third motor rotates, driving the rotating rod to rotate. The rotation of the rotating rod drives the connecting rod to move. The connecting rod can slide inside the rotating rod to prevent it from breaking. The movement of the connecting rod drives the movement of the disc, which in turn drives the movement of the rotating block. The rotating block moves around the pivot pin. At this time, the rotating rod continues to rotate, causing the rotating block to reverse. The reverse rotation of the rotating block drives the clamping plate to move, thereby driving the crease scraper to move. The crease scraper separates from the surface of the roller. The rotating rod continues to rotate, and the crease scraper approaches the roller until it is in contact with the roller. When the crease scraper comes into contact with the roller, the paper wrinkles. The continuous rotation of the third motor causes the crease scraper to swing continuously and make intermittent contact with the roller to achieve the purpose of crease. The crease scraper can only achieve the purpose of crease by making indirect contact with the paper through the swing mechanism. Attached Figure Description

[0026] See attached document Figure 1-2 And 4-5:

[0027] The swing mechanism 5 includes a third motor 501. The output shaft of the third motor 501 is fixedly connected to a rotating rod 502. The rotation of the output shaft of the third motor 501 drives the rotating rod 502 to rotate. The inner wall of the rotating rod 502 is slidably connected to a connecting rod 503.

The movement of the connecting rod 503 drives the disc 504 to move. The rotating shaft of the disc 504 is rotatably connected to a rotating block 505 through a bearing. The movement of the disc 504 drives the rotating block 505 to move. The outer walls on both sides of the rotating block 505 are rotatably connected to the second housing 4 through pins. The rotating block 505 is limited by the second housing 4 and rotates around the pins as the rotation center. A clamping plate 10 is fixedly connected to the outer wall of the rotating block 505.

[0028] Working principle:

[0029] Ceramic creping blades are used to crease paper during production.

[0030] The process of paper wrinkling:

[0031] The staff started the upper third motor 501 (such as...) Figure 2 The output shaft of the third motor 501 rotates, causing the rotating rod 502 to rotate (e.g.) Figure 4 The rotation of the rotating rod 502 drives the connecting rod 503 to move. The connecting rod 503 can slide within the rotating rod 502 during its movement to prevent it from breaking. The movement of the connecting rod 503 drives the disc 504 to move, which in turn drives the rotating block 505 to move. The rotating block 505 moves around the pivot pin. At this time, the rotating rod 502 continues to rotate, causing the rotating block 505 to reverse direction. The reverse rotation of the rotating block 505 drives the clamping plate 10 to move, thereby driving the wrinkling scraper 9 to move. The wrinkling scraper 9 disengages from the surface of the roller 11. When the rotating rod 502 rotates 180 degrees, the wrinkling scraper... When the distance between the 9 and the circular roller 11 is at its maximum, the rotating rod 502 continues to rotate, and the crease knife 9 moves closer to the circular roller 11 until the rotating rod 502 rotates another 180 degrees and the crease knife 9 comes into contact with the circular roller 11. When the paper comes into contact with the circular roller 11, the paper wrinkles. The third motor 501 rotates continuously, which makes the crease knife 9 swing continuously and make intermittent contact with the circular roller 11 to achieve the purpose of crease. The crease knife 9 in this case is a ceramic crease knife 9. The ceramic crease knife 9 has the characteristics of good crease effect, long service life, unique smoothing effect, high safety and wear resistance and corrosion resistance.

[0032] The process of polishing a wrinkled scraper:

[0033] Turn off the third motor 501, and then start the second motor 201 (e.g.) Figure 6The output shaft of the second motor 201 rotates forward, driving the worm gear 202 to rotate, which in turn drives the worm wheel 203 to rotate. The rotation of the worm wheel 203 drives the limit rod 204 to rotate and the two first housings 4 to rotate. The rotation of the first housings 4 drives the swing mechanism 5 to rotate, which in turn drives the crease scraper 9 to rotate. When the limit rod 204 is in contact with the limit plate 205 on the right, the second motor 201 stops. At this time, the worm wheel 203 rotates exactly 180 degrees. The rotation of the worm wheel 203 rotates 180 degrees, causing the upper and lower crease scrapers 9 to exchange positions. Then the third motor 501 on the upper side is started, so that the crease scraper 9 continues to process the paper, saving working time.

[0034] Then, cylinder 8 is activated. The output end of cylinder 8 extends, causing the support plate 12 to move to the left, thereby causing the grinding roller 6 and the first motor 7 to move to the left (e.g., ...). Figure 1 When the grinding roller 6 is in contact with the wrinkling scraper 9 on the lower side, the first motor 7 is started. The output shaft of the first motor 7 rotates, driving the grinding roller 6 to rotate and grind the wrinkling scraper 9. After grinding is completed, the output end of the control cylinder 8 is retracted, thus achieving the grinding of the wrinkling scraper 9. After all is completed, all power is turned off. If the two wrinkling scrapers 9 need to be swapped again, the output shaft of the second motor 201 is reversed so that the limit rod 204 is in contact with the limit plate 205 on the left. The worm 202 and worm wheel 203 have self-locking to fix the position of the two wrinkling scrapers 9.

[0035] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
