Technical Field

[0001] The utility model relates to the technical field of metal strip processing, in particular to a metal strip slitting machine. Background Art

[0002] The metal strip slitting machine is a device used to process metal strips. Its main function is to split metal strips into narrower strips. Through the automated slitting process, it can greatly improve production efficiency and reduce labor costs.

[0003] After searching, Chinese patent announcement number: CN220217792U discloses a metal strip slitting machine, including a slitting machine body, a grinding mechanism is arranged on the frame outlet side of the slitting machine body; the grinding mechanism includes a guide frame fixed to the side of the frame, a lifting seat is slidably installed in the guide frame, a protective shell is fixed between the lifting seats, and a plurality of grinding wheels are arranged on the upper surface of the protective shell along its length direction; and a driving device is also included, and the driving device is used to drive the grinding wheel to rotate synchronously. The utility model can drive the horizontal height adjustment of the grinding roller or grinding wheel by using a linear driving device, so that the grinding roller or grinding wheel is kept flush with the frame height of the slitting machine body, thereby facilitating the transmission of the metal strip, and the linear driving device can be used to switch between side grinding and plane grinding, thereby achieving the effect of deburring.

[0004] Although the above technology can achieve the effect of removing burrs from metal strips through grinding rollers or grinding wheels, there are still some shortcomings in the above technology. Since multiple grinding wheels in the above technology are connected by synchronous belts, the grinding wheels rotate in the same direction during rotation. Therefore, the effect of grinding the burrs on the metal strips is not ideal, resulting in the inability to completely clean the burrs on both sides of the metal strip. Therefore, the metal strip needs to be manually polished for a second time, which has poor practicality. For this reason, a metal strip slitting machine is proposed to solve the above problems. Utility Model Content

[0009] Through the above technical solution, by connecting one of the pulleys 1 to the output end of the motor, the pulley 1 can be rotated to realize that multiple grinding rollers 1 all rotate in the middle of the bracket.

[0010] As a further description of the above technical solution: the bottom of the support plate is rotatably connected to a rotating shaft, the outer periphery of the rotating shaft is provided with a second connecting component, the bottom of the rotating shaft is rotatably connected to a bevel gear, the middle of the bracket is provided with a grinding component, one end of the grinding component is fixedly connected to a bevel gear, and the two bevel gears are meshed with each other;

[0011] Through the above technical solution, by connecting component 2, the rotating shaft can be driven to rotate during the cleaning of both sides of the metal strip, and then the grinding component can be driven to clean the plane of the metal strip through the mutual engagement between the two bevel gears.

[0012] As a further description of the above technical solution: the connecting assembly 2 includes two pulleys 2, one of which is fixedly connected to an end of the rotating shaft away from the bevel gear, and the other pulley 2 is fixedly connected to the top of one of the pulleys 1, and the outer circumferences of the two pulleys 2 are sleeved with synchronous belts 2;

[0013] Through the above technical solution, through pulley two and synchronous belt two, one of the pulleys one can drive the pulley two to rotate, and through the synchronous belt two sleeved on the outer circumference, the other pulley two can drive the rotating shaft to rotate.

[0014] As a further description of the above technical solution: the grinding assembly includes two grinding rollers three, both of which are rotatably connected to the middle part of the bracket, one end of one of the grinding rollers three is fixedly connected to a gear two, one of the bevel gears is fixedly connected to one end of one of the grinding rollers three, the bevel gear is arranged on one side of the gear two, and one end of the other grinding roller three is fixedly connected to a gear one, and the gear one and the gear two are meshed with each other;

[0030] Specifically, first, the cutting mechanism includes: a cutter, a motor, a limit plate and other structures. This mechanism is a prior art and will not be described in detail here. The metal strip is cut into strips of a specific width to meet production needs, and then one of the grinding rollers 5 is driven to rotate by the motor 4, and then the grinding roller 5 in the middle of the bracket 1 is made to rotate synchronously through the connecting component 1, and then the gear 3 11 is driven to rotate synchronously while the grinding roller 1 5 rotates, and the multiple grinding rollers 2 6 and the multiple grinding rollers 1 5 are rotated in opposite directions through the mutual engagement between the gear 3 11 and the gear 4 12, and then the grinding roller 1 5 and the grinding roller 2 6 are respectively in contact with one side of the metal strip, and the rotation direction of the grinding roller 1 5 and the grinding roller 2 6 is opposite to the movement direction of the metal strip to solve the problem of poor burr cleaning effect.

[0031] Reference Figure 2 - Figure 3 The connecting component 1 includes a plurality of pulleys 13, and the plurality of pulleys 13 are respectively fixedly connected to the tops of the plurality of grinding rollers 5. The outer peripheries of two adjacent pulleys 13 are provided with a synchronous belt 14, and one of the pulleys 13 is fixedly connected to the output end of the motor 4. The plurality of gears 3 11 are all arranged at the end of the grinding roller 5 away from the pulley 13. The bottom of the support plate 3 is rotatably connected to a rotating shaft 17, and a connecting component 2 is arranged on the outer periphery of the rotating shaft 17. The bottom of the rotating shaft 17 is rotatably connected to a bevel gear 7. A grinding component is arranged in the middle of the bracket 1, and one end of the grinding component is fixedly connected to a bevel gear 7, and the two bevel gears 7 are meshed with each other.

[0032] Specifically, the connecting component 1 includes: a pulley 13 and a synchronous belt 14. The motor 4 drives one of the pulleys 13 to rotate, so that the other pulleys 13 can rotate synchronously through the synchronous belt 14 sleeved on the outer periphery, so that multiple grinding rollers 5 can rotate synchronously in the middle of the bracket 1, and the rotating shaft 17 can be driven to rotate through the connecting component 2, and then the two bevel gears 7 can be engaged with each other to drive the grinding component to grind the plane of the metal strip.

[0033] Reference Figure 2 - Figure 3 , the connecting component 2 includes two pulleys 2 15, one of which is fixedly connected to one end of the rotating shaft 17 away from the bevel gear 7, and the other pulley 2 15 is fixedly connected to the top of one of the pulleys 1 13. The outer periphery of the two pulleys 2 15 is provided with a synchronous belt 2 16. The grinding component includes two grinding rollers 3 8, and the two grinding rollers 3 8 are both rotatably connected to the middle part of the bracket 1.

The two grinding rollers 3 8 are not in contact with the grinding roller 1 5 and the grinding roller 2 6.

[0034] Specifically, the connecting component 2 includes: a pulley 2 15 and a synchronous belt 2 16. When the multiple grinding rollers 1 5 and the grinding roller 2 6 are rotated inside the bracket 1 by the driving motor 4, one of the pulleys 13 will drive one of the pulleys 2 15 to rotate, and then the synchronous belt 2 16 sleeved on the outer circumference of the two pulleys 2 15 can drive the rotating shaft 17 to rotate, and then the rotating shaft 17 will cause one of the bevel gears 7 to rotate during the rotation process, and then the two bevel gears 7 are engaged with each other, so that the grinding component grinds the plane of the metal strip, and the grinding component includes: a grinding roller 3 8, a gear 1 9, and a gear 2 10. When one of the grinding rollers 3 8 is driven to rotate by the bevel gear 7, one of the grinding rollers 3 8 will drive the gear 2 10 to rotate synchronously, and during the rotation process of the gear 2 10, the two grinding rollers 3 8 will rotate in the same direction through the mutual engagement with the gear 1 9, so as to achieve the effect of synchronously cleaning the burrs on both sides of the metal strip and on the plane.

[0035] Working principle: by driving one of the grinding rollers 5 to rotate through the motor 4, the pulley 13 arranged at one end of the grinding roller 5 can be rotated synchronously. When one of the pulleys 13 rotates, the synchronous belt 14 sleeved on the outer periphery of the pulley 13 can make multiple grinding rollers 5 rotate synchronously. When the grinding roller 15 rotates, it will drive the gear 3 11 to rotate. Then, through the mutual engagement between the gear 3 11 and the gear 4 12, the multiple grinding rollers 15 can drive the multiple grinding rollers 2 6 to rotate in the opposite direction through the gear 3 11 and the gear 4 12. Then, the rotation direction of the grinding roller 15 and the grinding roller 2 6 can be opposite to the moving direction of the metal strip to solve the problem of poor burr cleaning effect.

[0036] When the motor 4 drives one of the grinding rollers 15 to rotate, so that the other grinding rollers 15 also rotate synchronously through the synchronous belt 14 sleeved on the outer periphery of the pulley 13, one of the grinding rollers 15 will drive the pulley 2 15 to rotate, and then drive the rotating shaft 17 to rotate through the synchronous belt 2 16, and then the mutual engagement between the two rotating shafts 17 makes one of the grinding rollers 3 8 drive the gear 2 10 to rotate, and then the mutual engagement between the gear 2 10 and the gear 1 9 makes the other grinding roller 3 8 rotate in the opposite direction, so as to achieve the effect of synchronously cleaning the burrs on both sides of the metal strip and the plane, so as to solve the problem that the burrs on both sides of the metal strip and the plane cannot be cleaned at the same time.
