Description

Technical Field

[0001] The utility model relates to the technical field of operations, and particularly relates to a trimming mechanism of a high-speed slitting machine. Background Art

[0002] A slitting machine, also known as a slitting line, a slitting machine, or a slitting cutter, is a type of metal slitting equipment. The Chinese utility model patent with the authorization announcement number "CN216028401U" discloses a trimming mechanism of a high-speed slitting machine for high-precision copper strip processing. The outer wall of the first connection shell is fixedly connected with a trimming knife; a second connection shell is installed at the top end of a rotating shaft; an adjustment module includes a rotating block, a rotating rod, a scale disk, a clamping block, and a clamping groove. By setting a disassembly module in the utility model, when manually rotating a rotating ring, the rotation of the rotating ring drives the rotation of a second bevel gear. The rotation of the second bevel gear drives the rotation of a first bevel gear through meshing. The rotation of the first bevel gear drives a lead screw to rotate through a telescopic rod, so that the lead screw withdraws from a thread groove on the inner wall of the second connection shell, thereby separating the first connection shell and the second connection shell. Through the cooperation of the above multi-group connections, the function of quickly disassembling the trimming knife is realized.

[0003] In the above technical solution, the operator manually pulls the rotating block with a finger to rotate the rotating block to a vertical position, so that the rotating rod is no longer fixed. Then, the rotating block is rotated to drive the rotating rod to rotate by 90 degrees, so that the clamping block rotates from the inner wall of the clamping groove to a vertical position. Then, the operator can adjust the distance between each group of trimming knives through the scale disk. After adjusting the trimming knives, the above operations are repeated to drive the clamping block to reset, so that the clamping block is clamped inside the clamping groove, thereby fixing the rotating rod, so as to realize the function of adjusting multiple groups of trimming knives. However, the above technical solution still has certain defects. For example, in the above device, the operator can adjust the distance between each group of trimming knives through the scale disk, but the trimming knives are not positioned during the adjustment process. Therefore, the operator needs to continuously debug to make the clamping block clamped inside the clamping groove, which increases the workload of the operator and reduces the practicability of the device at the same time. Summary of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a trimming mechanism of a high-speed slitting machine, which can solve the problem that the operator of the device can adjust the distance between each group of trimming knives through the scale disk, but the trimming knives are not positioned during the adjustment process. Therefore, the operator needs to continuously debug to make the clamping block clamped inside the clamping groove, which increases the workload of the operator and reduces the practicability of the device at the same time.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A trimming mechanism of a high-speed slitting machine includes a fixed shaft, and a positioning device is arranged on the fixed shaft;

[0006] The positioning device includes a rotating block, a fixing plate and five connecting shells;

[0017] Second limiting block grooves are provided on both outer walls at the upper ends of the five fixing plates;

[0018] One ends of the two groups of limiting blocks close to the second limiting block grooves are respectively in contact with the inner walls of the corresponding second limiting block grooves;

[0019] The inner walls of the five connecting shells are respectively fixedly connected to both outer walls at the two ends of the corresponding fixing plate.

[0030] Compared with the prior art, the beneficial effects of the present utility model are:

[0031] For the trimming mechanism of the high-speed longitudinal shearing machine, when adjusting the trimming knife, the acting force generated during the movement of the trimming knife is used to make a group of limiting blocks disengage from the inside of a group of second limiting block grooves, and at the same time, a group of return springs contract. Then, when moving to another group, the acting force generated by another group of return springs on another group of limiting blocks makes another group of limiting blocks enter the inside of another group of second limiting block grooves to achieve positioning. In this way, it is avoided that the staff needs to continuously adjust when adjusting the trimming knife, effectively reducing the workload of the staff, and at the same time improving the practicability of the equipment.

[0032] For the trimming mechanism of the high-speed longitudinal shearing machine, after the fixing bolts are unscrewed with the help of tools and the trimming knife loses the limitation of the fixing bolts, the trimming knife can be removed from the connecting shell. In this way, it is convenient to disassemble the trimming knife, facilitating the maintenance and repair of the corresponding trimming knife, and effectively improving the working efficiency of the staff and the flexibility of the equipment.

[0043] Please refer to Figures 1-4 , the present invention provides a technical solution: a trimming mechanism for a high-speed slitting machine, including a fixed shaft 1;

[0044] A positioning device is provided on the fixed shaft 1;

[0045] The positioning device includes a rotating block 3, a fixing plate 14 and five connecting shells 6. One end of the outer wall of the fixed shaft 1 is provided with a rotating block groove 2, and the rotating block 3 is rotatably connected inside the rotating block groove 2. A rotating shaft 17 is rotatably connected inside the fixed shaft 1. One end of the rotating block 3 close to the rotating shaft 17 rotates and extends into the fixed shaft 1 and is fixedly connected to one end of the rotating shaft 17. The groove on the outer wall of the fixed shaft 1 is internally provided with eighteen first limiting block grooves 9. The eighteen first limiting block grooves 9 are grouped into nine in a group. Two groups of first limiting block grooves 9 are internally slidably connected with limiting blocks 11. Nine fixing blocks 16 are fixedly connected to the outer wall of the rotating shaft 17. Two groups of first limiting block grooves 9 are internally provided with return springs 10. The two ends of the two groups of return springs 10 are respectively fixedly connected to the inner wall of the corresponding first limiting block groove 9 and one end of the limiting block 11. Five fixing plates 14 are slidably connected to the outer wall of the rotating shaft 17. The upper sides of the outer walls of the five fixing plates 14 are both provided with second limiting block grooves 15. One ends of the two groups of limiting blocks 11 close to the second limiting block grooves 15 are respectively in contact with the inner walls of the corresponding second limiting block grooves 15. The inner walls of the five connecting shells 6 are respectively fixedly connected to the outer walls of the two ends of the corresponding fixing plates 14.

[0046] Among them, the outer walls of the five fixing plates 14 are all provided with second fixing block grooves 13. The interiors of the five second fixing block grooves 13 are all provided with first fixing block grooves 12. The nine fixing blocks 16 are respectively rotatably connected inside the corresponding first fixing block grooves 12 and the second fixing block grooves 13. The outer walls of the five connecting shells 6 are all provided with trimming knife grooves 7. Two trimming knives 4 are slidably connected inside the five trimming knife grooves 7. The ten trimming knives 4 are grouped into two in a group. The outer walls of the five connecting shells 6 are all provided with four fixing bolt grooves 8. The twenty fixing bolt grooves 8 are grouped into four in a group. Five groups of fixing bolt grooves 8 are internally threadedly connected with fixing bolts 5. The five groups of trimming knives 4 are respectively connected to the corresponding connecting shells 6 through the corresponding fixing bolts 5.

[0047] Furthermore, when using this device, it is started by connecting to an external power supply. First, when it is necessary to adjust the distance between the trimming knives 4, turn the rotating block 3 by 90 degrees. Then, while the rotating block 3 drives the rotating shaft 17 to rotate, it also drives the fixing block 16 to rotate. Then, after the fixing block 16 is opposite to the opening of the second fixing block groove 13 and the fixing plate 14 loses its limit, the trimming knives 4 can be adjusted.

[0048] Furthermore, adjust the acting force generated when the trimming knife 4 moves, so that a set of limit blocks 11 are disengaged from the inside of a set of second limit block grooves 15 while a set of return springs 10 contract. Then, when moving to another set, the acting force generated by the other set of return springs 10 on the other set of limit blocks 11 causes the other set of limit blocks 11 to enter the inside of the other set of second limit block grooves 15 to achieve positioning. Then, turn the rotating block 3 again to rotate and reset, and at the same time limit the trimming knife 4 to complete the adjustment. Then, when the trimming knife 4 needs to be disassembled, after using a tool to unscrew the fixing bolt 5, the trimming knife 4 can be removed from the connecting shell 6.

[0049] By adjusting the acting force generated when the trimming knife 4 moves in the positioning device, a set of limit blocks 11 are disengaged from the inside of a set of second limit block grooves 15 while a set of return springs 10 contract. Then, when moving to another set, the acting force generated by the other set of return springs 10 on the other set of limit blocks 11 causes the other set of limit blocks 11 to enter the inside of the other set of second limit block grooves 15 to achieve positioning. This avoids the need for workers to continuously adjust when adjusting the trimming knife 4, effectively reducing the workload of workers, and at the same time improving the practicability of the equipment. After using a tool to unscrew the fixing bolt 5, the trimming knife 4 loses the limitation of the fixing bolt 5, and then the trimming knife 4 can be removed from the connecting shell 6. This facilitates the disassembly of the trimming knife 4, is convenient for the maintenance and repair of the corresponding trimming knife 4, and effectively improves the work efficiency of workers and the flexibility of the equipment.

[0050] Working principle: First, when the distance between the trimming knives 4 needs to be adjusted, turn the rotating block 3 to rotate 90 degrees. Then, while the rotating block 3 drives the rotating shaft 17 to rotate, it also drives the fixed block 16 to rotate. Then, when the fixed block 16 is opposite to the opening of the second fixed block groove 13, the fixing plate 14 loses its limitation, and then the trimming knife 4 can be adjusted. Then, adjust the acting force generated when the trimming knife 4 moves, so that a set of limit blocks 11 are disengaged from the inside of a set of second limit block grooves 15 while a set of return springs 10 contract. Then, when moving to another set, the acting force generated by the other set of return springs 10 on the other set of limit blocks 11 causes the other set of limit blocks 11 to enter the inside of the other set of second limit block grooves 15 to achieve positioning. Then, turn the rotating block 3 again to rotate and reset, and at the same time limit the trimming knife 4 to complete the adjustment. Then, when the trimming knife 4 needs to be disassembled, after using a tool to unscrew the fixing bolt 5, the trimming knife 4 can be removed from the connecting shell 6.

[0051] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the gist of the present invention.
