Description

Technical Field

[0001] The utility model relates to the technical field of slitting equipment, in particular to a slitting equipment for producing a round packaging paper cover edge. Background Art

[0002] The wrapping paper cover is a packaging accessory made of micro-tile or white board paper for sealing other containers. The wrapping paper cover is mainly composed of a cylindrical rim and a cover plate. The circular wrapping paper cover rim is firstly compounded and rolled into a cylindrical shape by multiple layers of paper, and then cut and formed into a paper roll of a certain length, and finally the paper roll is put on the slitting equipment for slitting to obtain multiple cylindrical rims.

[0003] At present, the slitting equipment used for the production of round packaging paper cover edges is generally a rotating rod, and then a guide rail is installed on the machine table. A slide is slidably set on the guide rail, and a cutting tool is installed on the slide. The cutting tool is extended and retracted by a cylinder. When cutting, the slide moves at an equal distance. When stopping, the rotating rod rotates, and the cutting tool is pressed against the paper roll to cut a ring. Then the tool is recovered, and the slide continues to move a distance. The cutting tool is pressed against the paper roll again to cut the next ring. The above steps are repeated until the slitting of the entire paper roll is completed. This structure leads to low slitting efficiency. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Utility Model Content

The output shaft of the first motor 7 passes through the side plate 2 and is connected to the central position of the flipping block 8. At the central position of the end of the flipping block 8 far from the first motor 7, there is a central rod 9. The end of the central rod 9 far from the flipping block 8 is rotatably connected to the column 3. On both sides of the end of the flipping block 8 far from the first motor 7, there are symmetrically arranged bearing seats 11. The bearing seats 11 are connected with a rotating rod 10. At the end of the rotating rod 10 far from the bearing seat 11, there is a square hole 12. Inside the upper part of the column 3, there is a cross plate 13. On the upper surface of the cross plate 13, there is a guide rail 14;

[0025] The telescopic rotation mechanism includes a sliding plate 15, a second motor 16 and a first oil cylinder 17. The sliding plate 15 is slidably matched with the guide rail 14 through a slider. At the end of the sliding plate 15 far from the first motor 7, there is a vertical plate 18. On the upper surface of the sliding plate 15, there is also a second motor 16. The output shaft of the second motor 16 is connected to a shaft rod 19 through a coupling. The shaft rod 19 passes through the side wall of the column 3 and is provided with a square head 20. The square head 20 is matched with the square hole 12 of the rotating rod 10. The end of the square head 20 far from the shaft rod 19 is conical. The square hole 12 is matched with the square head 20 to facilitate the smooth insertion of the square head 20 into the square hole 12. The first oil cylinder 17 is arranged on the upper surface of the cross plate 13 through a support seat. The piston rod of the first oil cylinder 17 is connected to the end of the vertical plate 18 far from the second motor 16. The distance from the axis of the shaft rod 19 to the central rod 9 is the same as the distance from the axis of the rotating rod 10 to the central rod 9, so as to ensure that when the rotating rod 10 rotates to the position to be processed, the square hole 12 is exactly corresponding to the square head 20 at the end of the shaft rod 19. On both sides of the sliding plate 15 and at the connection with the vertical plate 18, there are reinforcing plates 26 to ensure the structural strength of the vertical plate 18 and avoid deformation during the pushing and pulling process;

[0026] The lifting and cutting mechanism includes a second oil cylinder 21, a lifting plate 22, a knife seat 23 and a slitting blade 24. The second oil cylinder 21 is arranged on the upper surface of the beam 6. The piston rod of the second oil cylinder 21 passes through the beam 6 and is connected to the lifting plate 22. The upper panel of the lifting plate 22 is also provided with a plurality of guide rods 25. The guide rods 25 pass through the beam 6 and are guided and matched with the cross plate 13 to ensure the stability of the lifting plate 22. A plurality of knife seats 23 are arranged on the lower surface of the lifting plate 22. The knife seats 23 are all equipped with slitting blades 24. The second motor 16, the second oil cylinder 21 and the slitting blade 24 are located in the same vertical plane to ensure that the shaft rod 19 at the end of the second motor 16, the second oil cylinder 21 and the slitting blade 24 respectively correspond to the positions of the rotating rod 10 at the position to be processed.

[0027] Working method and principle: First, put the paper roll of a certain length after cutting on the rotating rod 10, then drive the turning block 8 to rotate through the first motor 7, so that the rotating rod 10 with the paper roll is rotated to the bottom of the slitting blade 24. At this time, the first oil cylinder 17 pushes the vertical plate 18, and drives the second motor 16 to move along the guide rail 14 through the vertical plate 18 and the slide plate 15, so that the square head 20 at the end of the shaft rod 19 is inserted into the square hole 12 of the corresponding rotating rod 10, and then start the second motor 16, and the second motor 16 drives the corresponding rotating rod 10 to rotate through the shaft rod 19, so that the paper roll rotates. At the same time, start the second oil cylinder 21, the second oil cylinder 21 drives the lifting plate 22 to descend, and presses the slitting blade 24 on the paper roll, and cuts the paper roll into a ring. During slitting, another paper roll is manually put on the outer rotating rod 10. After slitting is completed, the lifting plate 22 rises, and the first oil cylinder 17 drives the second motor 16 to retreat, so that the square head 20 at the end of the shaft 19 is separated from the square hole 12 of the rotating rod 10. The first motor 7 drives the flip block 8 to rotate, so that the outer end of the slit paper roll rotates, and the material is manually removed and loaded. At the same time, the slitting process is performed on the other paper roll located below the slitting blade 24, so as to realize slitting and loading and unloading at the same time. The utility model has a reasonable structure. Rotating rods 10 are arranged on both sides of the flip block 8 through the bearing seat 11. When the rotating rod 10 is sleeved with a paper roll, it rotates to the second motor 16 and is connected and supported by the square head 20 of the shaft rod 19. The shaft rod 19 and the rotating rod 10 are driven to rotate by the second motor 16. At the same time, the slitting process is performed by the slitting blade 24 which can be lifted and lowered above. On the one hand, the slitting is performed at one time, and the efficiency is greatly improved. On the other hand, since the positions of the two rotating rods 10 are swapped by the flip block 8, when one rotating rod 10 supports the paper roll for slitting, the other rotating rod 10 is located on the outside of the machine 1 to realize unloading and loading, thereby further improving the production efficiency.

[0028] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

[0029] Finally, it should be noted that the above specific implementation manners are only used to illustrate the technical solutions of the present utility model rather than to limit them. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified and equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
