DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0021] Embodiment 1: A battery separator cutting device, such as Figure 1-5As shown, it includes a base 1, a discharge roller 2, a feed roller 3, a power roller 31, a motor 1 32, a mounting rod 4, a slitting roller 41, a mounting frame 5, a clamp 1 6, a clamp 2 61, a cutter 62, a spring 63, a rotating frame 8, a winding roller 9 and a motor 2 10. The base 1 is a carrier of the entire device and is used to install and support various components on the device. An opening for inserting the diaphragm is provided at the lower left part of the base 1. A discharge roller 2 is rotatably installed on the rear left side of the base 1 for unwinding the diaphragm mother roll that needs to be slit. Feed rollers 3 for changing the diaphragm conveying direction and assisting the diaphragm conveying are rotatably provided on both left and right sides of the base 1. A power roller 31 for driving and providing power for conveying the diaphragm is rotatably arranged at the right side of the base 1 near the right side feed roller 3. A motor 32 is fixedly installed at the right rear part of the base 1. The output shaft of the motor 32 is fixedly connected to the power roller 31. The power roller 31 and the right side feed roller 3 are in rolling contact with each other. Under the rolling friction of the power roller 31, the right side feed roller 3 rotates in the opposite direction as the power roller 31 rotates. A mounting rod 4 is rotatably arranged at the upper part of the base 1. The friction between the mounting rod 4 and the base 1 is large, and it is not easy to rotate under force. Four mounting brackets 5 are evenly spaced and fixedly installed on the mounting rod 4. The lower parts of the mounting brackets 5 are fixedly connected to the mounting rod 4. A card block 6 is connected, and a tool 62 is slidably arranged in the card block 6 for cutting the diaphragm, and needs to be replaced in time after being worn. A card block 2 61 is slidably arranged on the card block 6. Two card grooves are opened on the left and right sides of the upper part of the tool 62, and are clamped by the right part of the card block 1 6 and the left part of the card block 2 61. The card block 1 6 and the card block 2 61 are clamped in the tool, so that the tool 62 is fixedly connected to the card block 1 6 when in use, and does not move the position and rotate in the opposite direction. A spring 63 is wound around the outer side of the right part of the card block 2 61, and the two ends of the spring 63 are respectively connected to the card block 1 6 and the card block 2 61, which are used to provide a force to maintain the card block 2 clamping the tool 62. A slitting roller 41 is fixedly installed on the inner side of the seat 1. The slitting roller 41 is located directly below the mounting rod 4, and four grooves that match the upper tool 62 are evenly spaced on the slitting roller 41. The lower parts of the four tools 62 respectively extend into the grooves on the same side of the slitting roller 41 below. The slitting roller 41 is used to provide support when the tool 62 slits the diaphragm. The front right side of the base 1 is rotatably connected to a rotating frame 8, and the front part of the rotating frame 8 is rotatably connected to a winding roller 9 for winding the slit diaphragm. A motor 10 for providing winding power is installed inside the rotating frame 8, and the output shaft of the motor 10 is fixedly connected to the winding roller 9.

[0022] Initially, the mounting rod 4 is rotated 180 degrees upward, and the parts mounted on the mounting rod 4 are rotated 180 degrees upward along with the mounting rod 4. The cutter 62 and the groove on the slitting roller 41 are moved away from each other. The mother roll of the diaphragm to be slit is centrally mounted on the unwinding roller 2, and one end of the diaphragm is pulled out and inserted into the equipment from the lower left part of the base 1. At this time, the diaphragm surface is parallel to the ground. The diaphragm is passed through the lower part of the left feed roller 3, and then one end of the diaphragm is passed along the upper part of the slitting roller 41 to between the power roller 31 and the feed roller 3 on the right. The power roller 31 and the feed roller 3 on the right will clamp the passed diaphragm. When the power roller 31 rotates, under the friction between the power roller 31 and the surface of the feed roller 3 on the right, the feed roller 3 on the right moves along with the power The roller 31 rotates and reverses, and finally one end of the diaphragm is wound around the winding roller 9 and fixed on the winding roller 9. When the winding roller 9 rotates, the diaphragm will be rolled up. After one end of the diaphragm is fixed on the winding roller 9, the mounting rod 4 is rotated and reset. When the mounting rod 4 is reset, the lower parts of the four cutters 62 will cut the diaphragm and extend into the groove on the slitting roller 41 below. When the diaphragm is transported to the right, the cutter 62 will cut the diaphragm into strips. At this time, the motor 1 32 connected to the power roller 31 is started, and the motor 1 32 rotates clockwise. In cooperation with the right feeding roller 3, the diaphragm is pulled to be transported to the right. The unwinding roller 2 rotates to unwind the parent roll, and the cutter cuts the diaphragm transported to the right, and then the motor 2 10 is started. Control motor 2 10 to rotate and rewind the material. It should be noted that motor 2 10 is servo controlled. When the coiling roller 9 is rewinding, it will intermittently rewind according to the length of the diaphragm conveyed on the right side of the power roller 31 to avoid rewinding too quickly and pulling and damaging the diaphragm. The rotation of motor 2 10 drives the coiling roller 9 to rotate for rewinding. People place the slit diaphragms on the coiling roller 9 separately, not close to each other, so as to facilitate the separate placement when unloading. When the mother roll is unrolled, control motor 1 32 to turn off. After the rewinding is completed, turn off motor 2 10, then rotate the rotating frame 8 upward 90 degrees, and the coiling roller 9 is rotated and lifted. People take down the multiple diaphragm rolls that have been rewound after slitting to complete the slitting work. When the cutter 62 is unfavorably worn, burrs will be generated or the film surface will be torn during slitting, which is harmful to the material. The quality of cutting is affected. At this time, the fixed rod can be rotated 180 degrees upwards, and then the block 2 61 can be pulled apart, so that the block 1 6 and the block 2 61 are out of the stuck state with the slot of the tool 62, and the spring 63 is compressed. The tool 62 to be replaced is removed, and a new tool 62 is replaced, and the slot on one side is inserted into the block 1 6, and then the block 2 61 is released. Under the action of the spring 63, the block 2 61 slides back and is inserted into the slot on the other side of the tool 62 on the block 1 6 to complete the tool change. By setting a rotating mounting rod 4, when the tool 62 is replaced, the tool 62 is rotated to a space convenient for the replacement operation, and a movable block 2 61 is set to complete the quick tool change work, reduce the replacement time, and improve the efficiency.

[0023] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 and Figure 4 As shown, it also includes a fixed plate 11, a connecting plate 12 and a roll-dividing sheet 13. The fixed plate 11 is fixedly welded on the lower right inner side of the base 1. Four roll-dividing sheets 13 are slidably connected inside the fixed plate 11. The roll-dividing sheets 13 are used to guide and limit the multiple diaphragm rolls that are rolled up during rolling, so that the diaphragm rolls are neatly arranged when the film is rolled. A connecting plate 12 is connected between the lower parts of the roll-dividing sheets 13 for shifting all the roll-dividing sheets at one time.

[0024] like Figure 1 and Figure 4 As shown, it also includes a sliding rod 7. The sliding rod 7 is slidably and rotatably provided on the front upper side of the base 1. A hole groove with the same diameter as the sliding rod 7 is opened on the front of the mounting rod 4. The rear part of the sliding rod 7 is in sliding contact with the mounting rod 4. The front part of the sliding rod 7 is inserted into the slot on the mounting rod 4, which can fix the mounting rod 4 to prevent it from being displaced by force.

[0025] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a support block 14 is also included. The support block 14 is fixedly connected to the upper rear portion of the inner side of the base 1. The winding roller 9 is in rotational contact with the support block 14 to share the weight of the rotating winding roller 9 with the material.

[0026] like Figure 2 and Figure 5 As shown, a docking plate 15 is also included. The docking plate 15 is fixedly connected to the lower left inner side of the base 1. The left and right sides of the docking plate 15 are strip-shaped protrusions with long strip-shaped grooves, and the edges of the grooves are relatively smooth.

[0027] When arranging the mother roll film before slitting, first insert one end of the diaphragm into the slot on the left side of the docking plate 15, and then pass it out from the slot on the right side of the docking plate 15, and then carry out the subsequent cloth rolling work. When slitting, the mother roll needs to be replaced with a new mother roll after unwinding, and one end of the previous mother roll needs to be docked with one end of the new mother roll to continue the slitting work, one end of the new mother roll is inserted into the left side of the docking plate 15, and one end of the previous diaphragm is inserted into the other slot of the docking plate 15. On the plane of the docking plate 15, the two diaphragm rolls are neatly docked and adhered with a wide-surface tape to ensure neat docking. Before the coil roller 9 rewinds the slit diaphragm, the dividing roll sheet 13 is pushed upward through the connecting plate 12. The winding sheet 13 is made to slide to the winding roller 9. At this time, the winding roller 9 is located in the groove of the winding sheet 13. When the diaphragm that has been cut and needs to be wound up is on the winding roller 9, the rear parts of the cut multiple diaphragms are successively pressed against the front side of the winding sheet 13 on the same side, and the multiple diaphragm rolls that are rolled and wound are guided and arranged neatly through the winding sheet 13. The front part of the winding roller 9 is supported by the support block 14 to share the weight of the rotating winding roller 9 with material to avoid deformation of the rotating frame 8 under long-term work. When it is necessary to rotate the mounting rod 4, the sliding rod 7 is slid upward and rotated to one side. When cutting, the front part of the sliding rod 7 is inserted into the slot on the mounting rod 4 to fix it and avoid displacement due to force.

[0028] It should be understood that the above description is only for exemplary purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
