Description

Technical Field

[0001] The present invention relates to the technical field of diaphragm slitting, and in particular to a lithium battery diaphragm slitting machine and a control method thereof. Background Art

[0002] Film slitting machine is a kind of equipment used to slit wide film into narrow film. It usually adopts circular knife slitting or flat knife slitting. Its working process is to unwind the large roll of film through the unwinding device, pass through a series of guide rollers and tension control devices to keep the film at appropriate tension and flatness. Then, the slitting knife slits the film according to the set width, and the slit narrow film is wound into small rolls through the winding device.

[0003] When the existing film slitting machine is in operation, the cut film is recycled through the upper and lower cross-type receiving rollers, which makes it difficult to ensure that the machine is not involved after the operation. The film lacks the necessary tightness and relaxation when it is wound, resulting in the risk of stripe deformation on the surface of the film. At the same time, during the unloading process, since the receiving cylinder is placed in a more scattered manner and the spacing between the slit films is quite different, the film is easily pulled and collided during the unloading process, increasing the probability of wear and damage. At the same time, during the high-frequency operation of the machine, dust will inevitably fall off, resulting in impurity contamination when the film is recycled, affecting the quality of the film slitting. In addition, the loading and unloading of the workers affects the efficiency of the operation, making it difficult to meet the needs of large-scale production. In addition, the raw materials are set far away, which also leads to an increase in production time, reduced production efficiency, and increased production costs.

[0004] Therefore, the present application provides a lithium battery separator slitting machine and a control method thereof to meet the needs. Summary of the invention

The left end flip bracket begins to slowly descend under the action of the cylinder, the double-tooth flip piles are closed and erected, and the micro air pump reverses the air pumping. At this time, the expansion shaft contracts, and the upper and lower arc-shaped support frames move multiple groups of recycled films in parallel for unloading, and integrated recycling avoids the generation of pulling. At the same time, the recycling rollers on the same horizontal plane maintain the necessary tension and relaxation, avoiding excessive movement and vibration of the diaphragm, reducing the probability of deformation and damage, and improving production efficiency.

[0017] By setting up the material discharge adjustment component and utilizing the bidirectional screw rod, movable sleeve, upper and lower arc-shaped support frames, arc-shaped racks, gears, guide rods, arc-shaped scrapers, negative pressure fans, dust collecting boxes, limit plates and position sensors, the upper and lower arc-shaped support frames can well wrap the upper and lower surfaces of the recovery roller during the production process. At the same time, the negative pressure fan absorbs dust and impurities in the environment, thereby increasing the cleanliness of the environment, reducing film contamination, avoiding film damage, reducing cost increases, and maintaining production capacity. The distance sensor also ensures the distance between the film recovery roller and the production process, thereby avoiding wind interference and ensuring that the operation is carried out in an orderly and efficient manner. At the same time, the arc-shaped scraper also cleans the inside of the upper and lower arc-shaped support frames, thereby ensuring the cleanliness of the device at all times, increasing production capacity, and improving product quality.

[0018] By setting up a feeding adjustment component and utilizing a feeding rack, a slide, a partition, a load-bearing bar, a pulley, a positioning bar, a sill block and a weight sensor, after the film is unloaded, the paper core tubes evenly spaced on the load-bearing bar can be quickly clamped by rotating the movable sleeve, and the paper core tubes are positioned between the limit plates of the upper arc support frame and the lower arc support frame. At the same time, a negative pressure fan cleans the dust on the surface, and after turning it 180 degrees, it is loaded onto the expansion shaft and then manually removed from the sticky sticker on the surface of the paper core tube before it can be quickly put into use. The convenience of the feeding device reduces the loading time, improves the production efficiency, meets the requirements of large-scale production, saves time, improves the production efficiency and reduces costs.

When it moves to one end of the displacement sensor 65, the position The displacement sensor 65 sends a command to the control center 3 to stop moving. At this time, the paper core tube 611 is evenly arranged on the surface of the expansion shaft 610 by the limit plate 711 between the upper arc support frame 73 and the lower arc support frame 78. At this time, the cylinder 62 begins to contract. When the cylinder 62 contracts, the flip bracket 63 connected to the output end of the cylinder 62 begins to rotate. When the flip bracket 63 flips to one end of the gear shaft 66, the upper flip inner teeth 68 press against the gear shaft 66 and tighten inward until it rotates to the edge of the gear shaft 66 and bounces up. At this time, the upper flip inner teeth 68 and the arc inner teeth The teeth 69 are respectively engaged with the gear shaft 66. When the displacement sensor 65 transmits the command to the control center 3, the double-tooth flip pile 67 flips and is parallel to one end of the gear shaft 66. Then the micro air pump 612 starts to operate. When the micro air pump 612 operates, the expansion shaft 610 starts to expand. When the expansion shaft 610 expands, it begins to gradually fill the inner wall of the paper core tube 611. At this time, stop the micro air pump 612, tear off the sticky sticker on the surface of the paper core tube 611, adjust the film width, stick the film close to the paper core tube 611, start the motor 2 and the torque motor 64, and start the winding operation.

[0040] As an implementation method in this embodiment, Figures 7 to 11As shown, the material unloading adjustment component 7 includes a bidirectional screw rod 71, which is installed on the top of the material receiving rack 10, a servo motor 713 is installed at one end of the bidirectional screw rod 71, a movable sleeve 72 is installed on the surface of the bidirectional screw rod 71, an upper arc-shaped support frame 73 is installed on the top of the movable sleeve 72, a small motor 714 is installed at one end of the movable sleeve 72, the output end of the small motor 714 is meshed with the gear teeth inside one end of the movable sleeve 72, an arc-shaped rack 74 is installed at one end of the movable sleeve 72, a lower arc-shaped support frame 78 is installed at the bottom of the movable sleeve 72, a guide rod 76 is installed at the top end of the lower arc-shaped support frame 78, a gear 75 is installed at one end of the guide rod 76, and the arc-shaped rack 74 is installed on the movable sleeve 75. On the moving track, the surface of the guide rod 76 is sleeved with an arc scraper 77, the bottom of the arc scraper 77 is in contact with the surface of the lower arc support frame 78, and limit plates 711 are installed at both ends of the bottom of the lower arc support frame 78. The distance between the limit plates 711 is the same as the length of the paper core tube 611. Multiple groups of negative pressure fans 79 are installed inside the lower arc support frame 78, and dust collection boxes 710 are installed at the bottom of the multiple groups of negative pressure fans 79. A distance sensor 712 is installed on the top of the inner wall of the upper arc support frame 73. When the film starts to be wound, the unloading adjustment component 7 starts to operate. At this time, the upper arc support frame 73 and the lower arc support frame 78 are respectively located above and below the paper core tube 611. While ensuring the cleanliness of the winding environment, the negative pressure fan 79 starts Operation, when the negative pressure fan 79 starts to absorb the surrounding dust, the collected dust enters into the dust collecting box 710 at one end of the negative pressure fan 79 for collection. At this time, the film is wrapped thicker and thicker, and the distance sensor 712 starts to feedback the distance instruction to the control center 3, so that the upper arc support frame 73 and the lower arc support frame 78 always keep a distance from the film on the paper core tube 611. When the film is wound, the torque motor 64 starts to stop running. When the torque motor 64 stops running, the micro air pump 612 starts to pump air, and the expansion shaft 610 starts to shrink. At this time, the paper core tube 611 starts to relax, and the lower arc support frame 78 starts to lift the paper core tube 611 wrapped with the film upwards, so that it is stuck between the limit plates 711, and the servo is started. The servo motor 713 moves the movable sleeve 72 on the bidirectional screw rod 71. When the paper core tube 611 leaves the displacement sensor 65, the double-tooth flip pile 67 starts to stand up and close together. At this time, the cylinder 62 controls the flip bracket 63 to flip downward, and then the lower arc support frame 78 transports the film out for unloading. Then the servo motor 713 drives the movable sleeve 72 to reset.

During the flipping process of the movable sleeve 72, the gear 75 will mesh with the arc rack 74 at one end of the movable sleeve 72. After meshing, the gear 75 starts to rotate. When the gear 75 rotates, the guide rod 76 meshingly connected at one end of the gear 75 rotates. When the guide rod 76 rotates,The arc scraper 77 mounted on the surface of the guide rail 76 begins to scrape the dust from the inner wall of the lower arc support frame 78, and then the scraped dust is absorbed into the dust box 710 by the negative pressure fan 79.

[0041] As an implementation method in this embodiment, Figures 7 to 13 As shown, the feeding adjustment component 8 includes a feeding rack 81, which is mounted on the surface of the receiving rack 10, a slideway 82 is installed inside the feeding rack 81, a partition 83 is installed at the front end of the feeding rack 81, a load-bearing bar 84 is installed at the bottom of the partition 83, a pulley 85 is installed at one end of the load-bearing bar 84, a positioning bar 86 is installed at one end of the partition 83, a sill block 87 is installed at the bottom end of the feeding rack 81, and a weight sensor 88 is arranged above the partition 83. When the movable sleeve 72 is turned over, the feeding adjustment component on the surface of the receiving rack 10 8 starts feeding, and multiple groups of paper core tubes 611 follow the slide 82 inside the feeding frame 81, roll to the positioning strip 86 and calibrate the position, and then move to the load-bearing strip 84 divided by multiple groups of partitions 83, roll to the surface of the pulley 85 and stop moving. At this time, under the action of gravity, the weight sensor 88 raises the sill block 87 to stop the paper core tube 611 from continuing to slide down. Then, when the lower arc support frame 78 rises and turns over, the paper core tube 611 on the load-bearing strip 84 is lifted up and stuck on the inner wall of the limit plate 711, and then clamped with the upper arc support frame 73.

[0042] The working principle of the technical solution provided by the present invention is as follows: First, check whether the parts of the film slitting machine on the body 1 are loose, check whether the guide rollers 4 are firmly connected, and whether the cutters are blunt. Load the film roll 9, electrically adjust the spacing between the laser projectors 5 through the control center 3, and after the staff manually adjusts the distance between adjacent cutters, pass the film roll through the guide rollers 4 and the slitting cutters, and then introduce it into the winding adjustment component 6.

[0043] When the film is rolled into and introduced into the winding adjustment component 6, it starts to pass through the paper core tube 611 clamped between the upper arc support frame 73 and the lower arc support frame 78, and is parallelly sleeved from one end of the gear shaft 66 through one end of the fixed frame 61, and then the servo motor 713 drives the bidirectional screw rod 71 to drive the movable sleeve 72, driving the paper core tube 611 clamped by the unloading adjustment component 7 to move parallel to the surface of the expansion shaft 610. When it moves to one end of the displacement sensor 65, the displacement sensor 65 sends a command to the control center 3 to stop moving. At this time, the paper core tube 611 is evenly arranged on the surface of the expansion shaft 610 by the limit plate 711 between the upper arc support frame 73 and the lower arc support frame 78. At this time, the cylinder 62 begins to contract. When the cylinder 62 contracts, the flip bracket 63 connected to the output end of the cylinder 62 opens When the flip bracket 63 flips to one end of the gear shaft 66, the upper flip inner teeth 68 press against the gear shaft 66 and tighten inward until it bounces up when it rotates to the edge of the gear shaft 66. At this time, the upper flip inner teeth 68 and the arc-shaped inner teeth 69 are respectively engaged with the gear shaft 66, driving the double-tooth flip pile 67 to flip and be parallel to one end of the gear shaft 66. After the displacement sensor 65 transmits the instruction to the control center 3, the control center 3 then controls the micro air pump 612 to start operating. When the micro air pump 612 operates, the expansion shaft 610 starts to expand. When the expansion shaft 610 expands, it begins to gradually fill the inner wall of the paper core tube 611. At this time, stop the micro air pump 612, tear off the sticky sticker on the surface of the paper core tube 611, adjust the film width, and stick the film to the paper core tube 611. Start the motor 2 and the torque motor 64 to start the winding operation.

[0044] When the film starts to be wound, the material unloading adjustment component 7 starts to operate. At this time, the upper arc support frame 73 and the lower arc support frame 78 are respectively located above and below the paper core tube 611. While ensuring the cleanness of the winding environment, the negative pressure fan 79 starts to operate. When the negative pressure fan 79 starts to absorb the surrounding dust, the collected dust enters the dust collecting box 710 at one end of the negative pressure fan 79 for collection. At this time, the film is wound thicker and thicker, and the distance sensor 712 starts to feedback the distance instruction to the control center 3, so that the upper arc support frame 73 and the lower arc support frame 78 always keep a distance from the film on the paper core tube 611. When the film is wound, the torque motor 64 starts to stop running. When the torque motor 64 stops running, the micro air pump 612 starts to pump air, and the expansion shaft 610 starts to shrink. At this time, the paper core tube 611 starts to relax, and the lower arc support frame 78 starts to lift the paper core tube 611 wrapped with the film upwards, so that it is stuck between the limit plates 711. The servo motor 713 is started to move the movable sleeve 72 on the bidirectional screw rod 71. When the paper core tube 611 leaves the displacement sensor 65, the double-toothed flip pile 67 starts to stand up and close together. At this time, the cylinder 62 controls the flip bracket 63 to flip downward, and then the lower arc support frame 78 transports the film out for unloading. After that, the servo motor 713 drives the movable sleeve 72 to reset. At this time, the control center 3 controls the small motor 714 to drive the movable sleeve 72 to start flipping the direction of the feeding rack 81. The movable sleeve During the flipping process of the cylinder 72, the gear 75 will mesh with the arc-shaped rack 74 at one end of the movable sleeve 72. When the gear 75 meshes with the arc-shaped rack 74, it starts to rotate. When the gear 75 rotates, the guide rod 76 meshingly connected to one end of the gear 75 rotates. When the guide rod 76 rotates, the arc-shaped scraper 77 installed on the surface of the guide rod 76 starts to scrape the dust on the inner wall of the lower arc-shaped support frame 78, and then the scraped dust is absorbed into the dust collecting box 710 through the negative pressure fan 79.

[0045] When the movable sleeve 72 is flipped, the feeding adjustment component 8 on the surface of the receiving rack 10 starts feeding, and the multiple groups of paper core tubes 611 follow the slide 82 inside the feeding rack 81, roll to the positioning bar 86 and calibrate the position, and then move to the load-bearing bar 84 divided by the multiple groups of partitions 83, roll to the surface of the pulley 85 and stop moving. At this time, under the action of gravity, the weight sensor 88 raises the sill block 87 to prevent the paper core tube 611 from continuing to slide down. Then, when the lower arc support frame 78 is raised and flipped, the paper core tube 611 on the load-bearing bar 84 is lifted up and stuck on the inner wall of the limit plate 711, and then clamped with the upper arc support frame 73. After flipping to one end of the winding adjustment component 6, the paper core tube 611 is fed.

[0046] The present application also provides a control method for a lithium battery separator slitting machine, comprising the following steps: S1: First, check whether the connection between the guide rollers 4 of the film slitting machine is firm, install the film roll 9, electrically adjust the distance between the laser projectors 5 through the control center 3, and after the personnel manually adjust the corresponding distance of the tool, the film roll passes through the guide roller 4 and the slitting tool, and then is introduced into the winding adjustment component 6; S2: After the device is tested, the paper core tube 611 is clamped by the material discharging adjustment component 7 and evenly arranged on the surface of the expansion shaft 610. The control center 3 starts the micro air pump 612 to start supplying air. After the expansion shaft 610 expands and fills the inside of the paper core tube 611, the film is connected to the surface of the paper core tube 611, and the device is started to start winding; S3: When the winding is completed, the material unloading adjustment component 7 unloads and places the wound film paper core tube 611, and then after the material unloading adjustment component 7 returns to the initial position, the small motor 714 is started to drive the movable sleeve 72 to rotate toward the receiving rack 10. During the rotation, the gear 75 is triggered to rotate to scrape the dust from the internal surface, and the negative pressure fan 79 absorbs and stores the dust; S4: After unloading is completed, the feeding adjustment component 8 starts feeding, so that the paper core tube 611 in the feeding rack 81 rolls onto the load-bearing bar 84, and the small motor 714 continues to drive, so that the unloading adjustment component 7 clamps the paper core tube 611 and rotates toward the winding adjustment component 6, and then installs the paper core tube 611 onto the expansion shaft 610.
