[0038] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0039] Reference Figs. 1-3 For the first embodiment of the present application, a web roller capable of measuring the amount of carrier liquid is provided, comprising: a rack 1; a first rotating roller 2 rotatably arranged on the rack 1, the first rotating roller 2 being used for carrying glue; a second rotating roller 3 rotatably arranged on the rack 1, the first rotating roller 2 and the second rotating roller 3 having a glue applying gap 21 therebetween, the cloth abutting against the first rotating roller 2 through the glue applying gap 21; a lamp strip 4 arranged on the rack 1 and located above the first rotating roller 2, the lamp strip 4 being used for irradiating the first rotating roller 2.

[0040] In this embodiment, the lamp strip 4 is used to irradiate the surface of the anilox roller, and the width of the shadow stripe formed by the lamp strip 4 is used to determine the amount of carrier liquid. This method can determine the thickness change within 0-0.5um, and the change of the amount of carrier liquid is clear and intuitive and can be visualized. Employees can understand the change of the amount of carrier liquid according to the width change of the lamp strip 4 and quickly adjust the thickness. The skill requirement of the employees is reduced, and the thickness consistency change can also be monitored through the change of the amount of carrier liquid. A fixed tool is used to install the lamp strip 4 above the first rotating roller 2, the length of the lamp strip 4 is greater than or equal to the length of the first rotating roller 2 (greater than or equal to 1300mm), the height of the lamp strip 4 from the first rotating roller 2 is about 330mm, the brightness of the lamp strip 4 is 100-200nit, and after installation, it is checked whether the shadow stripe formed by the lamp strip 4 is convenient to observe and whether a clear stripe is formed. If there is an abnormality, the height and angle can be adjusted slightly to improve it. Turn on the light, and the employee stands in front of the first rotating roller 2 and observes the shadow stripe on the first rotating roller 2 with his eyes. The wider the width, the less sizing liquid on the first rotating roller 2, the thinner the thickness, the narrower the shadow stripe, the more sizing liquid on the first rotating roller 2, the thicker the thickness, and if the width changes back and forth, it means that the thickness is fluctuating and needs to be adjusted.

[0041] Further, the scraper 5 is rotatably arranged on the frame 1, and the scraper 5 abuts against the first rotating roller 2. The scraper 5 is slidably and rotatably arranged on the frame 1. The first rotating roller 2 is an anilox roller.

[0042] In this embodiment, the first rotating roller 2, i.e. the anilox roller, is made of high-strength alloy steel material, and the surface pattern of the anilox roller is processed by advanced laser engraving technology. The line number, depth and shape of the pattern are customized and designed according to the requirements of the coating process. The second rotating roller 3 is made of polyurethane rubber material with good wear resistance and elasticity, and the surface is treated by special anti-sticking process to effectively prevent the coating from adhering and accumulating on the surface. The second rotating roller 3 is also rotatably installed on the frame 1 through a bearing seat, and its installation position can be adjusted by a precise screw nut mechanism, so as to accurately adjust the glue coating gap 21 between the first rotating roller 2. The adjustment range of the glue coating gap 21 is between 0.1-1mm, which can adapt to the coating requirements of substrates with different thicknesses and materials. In the coating process, the material to be coated (such as lithium battery separator material) passes through the glue coating gap 21 with stable tension and speed, fully contacts with the coating on the surface of the first rotating roller 2, and realizes uniform coating under the extrusion of the second rotating roller 3. The scraper 5 can slide to facilitate the adjustment of the position of the scraper 5 during equipment debugging and operation. The scraper 5 always maintains contact with the surface of the first rotating roller 2 under the action of the spring mechanism, and the pressure of the spring can be accurately set by adjusting the nut, so as to ensure that the glue scraping pressure of the scraper 5 on the anilox roller is stable within a suitable range.

[0043] Further, the mounting shell 6 is arranged on the rack 1; one end of the first sliding rod 7 is arranged in the mounting shell 6 in a transverse sliding manner, and the other end is in abutment with the first rotating roller 2, the first rotating roller 2 is used to drive the first sliding rod 7 to slide; one end of the second elastic member 8 is arranged on the first sliding rod 7, and the other end is arranged on the mounting shell 6, the second elastic member 8 is used to provide a force for the first sliding rod 7 to abut against the first rotating roller 2; the first alarm unit 9 is arranged in the mounting shell 6, and after the first sliding rod 7 slides, the first sliding rod 7 extrudes the first alarm unit 9.

[0044] In the embodiment, one end of the first sliding rod 7 can slide in the transverse direction on the guide rail in the mounting shell 6, and the other end of the first sliding rod 7 is in surface contact with the first rotating roller 2; when the first rotating roller 2 rotates normally, the second elastic member 8 is in a normal state, and the other end of the first sliding rod 7 is always in abutment with the first rotating roller 2; in order to reduce the friction between the first rotating roller 2 and the first sliding rod 7, a ball can be designed at the other end of the first sliding rod 7, and the ball is in contact with the first rotating roller 2. When the first rotating roller 2 rotates normally, the first sliding rod 7 is relatively fixed with the mounting shell 6, and the second elastic member 8 is in a state of not being compressed and not being elongated; when the first rotating roller 2 is misaligned, the first rotating roller 2 starts to extrude the first sliding rod 7, and drives the first sliding rod 7 to slide in the transverse direction. The first alarm unit 9 adopts a micro pressure sensor; when the first sliding rod 7 slides due to the abnormality of the first rotating roller 2, the first sliding rod 7 extrudes the pressure sensor, and the pressure sensor transmits a signal to the control system, so that the first alarm unit 9 alarms.

[0045] The combination of the first sliding rod 7, the second elastic member 8 and the first alarm unit 9 realizes real-time monitoring of the working state of the first rotating roller 2. When the first rotating roller 2 has an abnormal condition, the first sliding rod 7 will quickly sense and displace, and then trigger the first alarm unit 9 to send a signal to the control system.

[0046] Further, the first sliding block 10 is arranged in the mounting shell 6 in a longitudinal sliding manner, and the first sliding block 10 has a first guide inclined surface 101; after the first sliding rod 7 abuts against the first guide inclined surface 101, the first sliding block 10 extrudes the first alarm unit 9.

[0047] In the embodiment, when the first sliding rod 7 displaces and slides due to the abnormality of the first rotating roller 2, the first sliding rod 7 abuts against the first guide inclined surface 101 of the first sliding block 10; due to the action of the first guide inclined surface 101, the transverse displacement of the first sliding rod 7 is converted into the longitudinal displacement of the first sliding block 10, and the first sliding block 10 extrudes the pressure switch, and the pressure switch transmits a signal to the control system.

[0048] The cooperation between the first sliding block 10 and the first sliding rod 7 converts the longitudinal displacement of the first sliding rod 7 into the transverse displacement of the first sliding block 10 through the first guide slope 101, thereby triggering the first alarm unit 9. This structural design makes the fault detection more sensitive and accurate, and can effectively detect the slight abnormal changes on the surface of the first rotating roller 2. Even if the first rotating roller 2 has an abnormal change of only a few microns, it can also be quickly detected and an alarm can be sent.

[0049] Further, one end of the second sliding rod 14 is transversely and slidably arranged in the mounting shell 6, and the other end is in abutment with the first rotating roller 2, and the first rotating roller 2 drives the second sliding rod 14 to slide; one end of the third elastic member 15 is arranged on the second sliding rod 14, and the other end is arranged on the mounting shell 6, and the third elastic member 15 is used to provide the force for the abutment of the second sliding rod 14 with the first rotating roller 2; the second alarm unit 11 is arranged in the mounting shell 6, and after the first sliding rod 7 slides reversely, it presses the second alarm unit 11. The second sliding block 12 is longitudinally and slidably arranged in the mounting shell 6, and the first sliding block 10 and the second sliding block 12 are respectively located on the two sides of the first sliding rod 7 and the second sliding rod 14, and the sliding directions of the first sliding block 10 and the second sliding block 12 are opposite. The second sliding block 12 has a second guide slope 121, and after the second sliding rod 14 abuts against the second guide slope 121, it drives the second sliding block 12 to press the second alarm unit 11. The first elastic member 13 has two ends, one end is arranged on the mounting shell 6, and the other end is arranged on the first sliding block 10 and / or the second sliding block 12, and the first elastic member 13 is used to provide the force for the reset of the first sliding block 10 or the second sliding block 12. A telescopic guide rod can be designed between the first sliding rod 14 and the mounting shell 6, and the third elastic member 15 is sleeved outside the telescopic guide rod to prevent the second sliding rod 14 from being dislocated.

[0050] In this embodiment, one end of the first sliding rod 7 is in contact with the surface of the first rotating roller 2, and the other end is adapted with the first guide slope 101 of the first sliding block 10 and the second guide slope 121 of the second sliding block 12. One end of the second sliding rod 14 is in contact with the surface of the first rotating roller 2, and the other end is adapted with the second guide slope 121 of the second sliding block 12. The first sliding block 10 and the second sliding block 12 are respectively located on the two sides of the first sliding rod 7 and the second sliding rod 14 and longitudinally slide in the mounting shell 6. The angles of the first guide slope 101 of the first sliding block 10 and the second guide slope 121 of the second sliding block 12 are designed, and when the first sliding rod 7 and the second sliding rod 14 are displaced due to the abnormal state of the first rotating roller 2, the displacement of the first sliding rod 7 and the second sliding rod 14 can be converted into the longitudinal displacement of the first sliding block 10 or the second sliding block 12. The first alarm unit 9 and the second alarm unit 11 both adopt high-reliability pressure sensors, and when the first sliding rod 7 slides in different directions due to the abnormality of the first rotating roller 2, it will press the corresponding sliding block, and the sliding block will further press the corresponding pressure sensor.

[0051] The first slider 10, the second slider 12 and the first slide rod 7, the second slide rod 14 are cooperatively designed, cooperate with the first alarm unit 9 and the second alarm unit 11, and can comprehensively detect various abnormal conditions of the first rotating roller 2. In the initial state, the second elastic member 8 is not compressed and elongated, the first rotating roller 2 is in contact with the first slide rod, when the first rotating roller 2 approaches the first slide rod 7, the first slide rod 7 is driven to slide, and the first slide rod 7 extrudes the first slider 10. The first slider 10 extrudes the first alarm unit 9, the first alarm unit 9 rings, and when the first rotating roller 2 is reset, the second elastic member 8 drives the first slide rod 7 to reset, and the first alarm unit 9 stops ringing. Conversely, in the initial state, the third elastic member 15 is in a compressed state, when the first rotating roller 2 is away, the second slide rod 14 is driven by the third elastic member 15 to slide with the first rotating roller 2, after the second slide rod 14 slides, the second slide rod 14 extrudes the second slider 12, the second slider 12 extrudes the second alarm unit 11, the second alarm unit 11 rings, and the ringing sound of the first alarm unit 9 and the second alarm unit 11 is inconsistent. When the first rotating roller 2 jumps, the first alarm unit 9 and the second alarm unit 11 will ring cyclically. Because the first alarm unit 9 and the second alarm unit 11 have different sounds, workers can preliminarily judge the abnormal condition of the first rotating roller 2 according to different alarm sounds. Timely and accurate fault alarm enables the operator to quickly respond to the abnormal condition of the first rotating roller 2, and avoids further deterioration of the fault to affect production.
