Description

Technical Field

[0001] The utility model relates to the technical field of paper product processing, in particular to a coil roller for slitting rolled paper. Background Art

[0002] The roll drum is the slitting component on the paper slitting machine. Currently, the most common paper rolls are large rolls of 1.4 to 1.7 meters wide, which is not only convenient for production but also for transportation. During production, each paper manufacturer needs to slit the large rolls of paper according to different uses and needs, and cut out rolls of different sizes and rules for use.

[0003] However, the slitting rollers in the existing roll paper slitting machines are not easy to disassemble and replace. They are all sleeved on the rotating rollers for use. When the slitting rollers need to be disassembled, the rotating rollers need to be removed first, and then the slitting rollers are taken off the rotating rollers one by one, and then the new slitting rollers are re-sleeved on the rotating rollers for use. This method of disassembly and replacement is slow, and it is not convenient to quickly disassemble, replace and install the slitting rollers, which reduces work efficiency. Therefore, it is necessary to design a roll paper slitting roller that is easy to disassemble, replace and install. Utility Model Content

[0004] In order to overcome the deficiency in the prior art that the slitting drum of a roll paper slitting machine is not convenient to quickly disassemble, replace and install, one of the purposes of the utility model is to provide a roll paper slitting roll.

The slitting roller is easily installed and removed, thereby improving the replacement efficiency of the slitting roller.

[0006] According to the roll material roller for paper slitting, a knob is fixedly connected to one side of the mounting rod to facilitate the rotation of the mounting rod.

[0007] According to the roll material roller for paper slitting, the size of the slitting roller is adapted to the size of the through slot and the inner wall of the connecting frame, thereby supporting the slitting sleeve and effectively improving the rotational stability of the slitting sleeve.

[0008] According to the roll material roller for paper slitting, a pull ring is fixedly connected to the outer surface of one side of the hollow rotating rod, so as to facilitate pulling the hollow rotating rod.

[0009] According to the roll roller for paper slitting, one end of the support roller is fixedly connected to a first fixing plate, and the other end of the support roller is fixedly connected to a second fixing plate. A first through-hole is defined on one side of the first fixing plate, and the hollow rotating rod is rotatably connected to the inner wall of the first through-hole. The first through-hole supports the hollow rotating rod, thereby improving its stability.

[0010] According to the roll for paper slitting, the outer diameter of the hollow rotating rod is consistent with the inner diameter of the first through hole, which facilitates the rotation of the hollow rotating rod in the first through hole and effectively improves the stability of the hollow rotating rod.

[0011] According to the aforementioned roll-to-roll paper slitting roller, a second through-hole is formed on one side of the second fixing plate, a servo motor is fixedly connected to one side of the second fixing plate, a rotating shaft is fixedly connected to one side of the rotating shaft, a plug-in sleeve is fixedly connected to one side of the rotating shaft, the plug-in sleeve passes through the second through-hole and is rotatably connected to the inner wall of the second through-hole, and a plug-in component is fixedly connected to the side of the hollow rotating rod adjacent to the plug-in sleeve, thereby providing power for the rotation of the slitting roller.

[0012] According to the roll roller for paper slitting, the size of the plug-in component matches the size of the plug-in sleeve, and the plug-in component is plugged into the inner wall of the plug-in sleeve, so as to facilitate driving the hollow rotating rod to rotate.

[0013] The above scheme has the following beneficial effects:

[0014] 1. Through the arrangement of the hollow rotating rod, threaded hole, mounting rod, movable plate, insert block and slot, the mounting rod is screwed outward to separate it from the movable plate, the movable plate is pushed toward the side away from the slot to drive the insert block to separate from the slot, and the hollow rotating rod is pulled to drive it to separate from the supporting roller, thereby removing the slitting drum from the through slot and the inner wall of the connecting frame, thereby facilitating the disassembly and replacement of the slitting drum. Compared with the existing method of first removing the supporting roller and then removing the slitting drum from the supporting roller, it is more convenient and effectively improves the replacement efficiency of the slitting drum.

[0015] 2. Through the arrangement of the plug-in component, the plug-in sleeve and the hollow rotating rod, the plug-in component is plugged into the inner wall of the plug-in sleeve to drive the hollow rotating rod to rotate. The rotation of the hollow rotating rod drives the slitting drum to rotate through the plug block and the slot to slit the paper roll. The support roller plays the role of limiting support, which effectively improves the rotation stability of the slitting drum.

A servo motor 19 is fixedly connected to one side of the second fixed plate 16. A rotating shaft 20 is fixedly connected to the output end of the servo motor 19. A plug-in sleeve 21 is fixedly connected to one side of the rotating shaft 20. The plug-in sleeve 21 extends through the second through hole 18 and is rotatably connected to the inner wall of the second through hole 18. A plug-in connector 22 is fixedly connected to the side of the hollow rotating rod 5 near the plug-in sleeve 21. The size of the plug-in connector 22 matches the size of the plug-in sleeve 21 and is plugged into the inner wall of the plug-in sleeve 21. The servo motor 19, the plug-in sleeve 21, the rotating shaft 20, and the plug-in connector 22 cooperate to drive the hollow rotating rod 5 to rotate. The rotation of the hollow rotating rod 5 drives the multiple slitting rollers 4 to rotate through the plug block 7 and the slot 6, thereby facilitating the slitting of the paper roll.

The hollow rotating rod 5 rotates through the plug block 7 and the slot 6 to drive multiple slitting rollers 4 to rotate, thereby cutting the roll of paper. When it is necessary to disassemble and replace the slitting roller 4, the knob 13 is turned to drive the mounting rod 12 to rotate out of the position where the fixed movable plate 8 is not fixed on the inner wall of the threaded hole 11, and the movable plate 8 is pushed to drive the plug block 7 to disengage the slot 6, and then the pull ring 14 is pulled to drive the hollow rotating rod 5 to move outward from the inner wall of the support roller 1, thereby disassembling and replacing multiple slitting rollers 4. Compared with the existing method of first removing the support roller 1 and then removing the slitting roller 4 from the support roller 1, it is more convenient and effectively improves the replacement efficiency of the slitting roller 4.
