[0012] Beneficial effects

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This utility model discloses a slitting device for a rewinding machine. A gold cardstock reel with a loose edge is placed on an unwinding roller and wound up using a take-up roller. Multiple guide rollers and slitting components pass through the rewinding process. The distance between the two end blades is adjusted according to the required gold cardstock size. Rotating a knob drives a threaded rod, which in turn drives a slider downwards, causing the end blades to press against the gold cardstock. The winding is achieved with an external motor driving the take-up roller. During winding, the end blades cut the loose edge of the gold cardstock. The cut gold cardstock meets the standard and can be used without being scrapped, saving materials and reducing consumption. By setting a threaded sleeve and matching blade ring blocks, multiple matching blade ring blocks can be added to the threaded sleeve to form different distances of entry grooves when cutting gold cardstock of different sizes, thus meeting the needs of multiple sizes.

Detailed Implementation

[0021] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0022] See Figure 1-5 As shown, a slitting device for a rewinding machine according to this utility model includes an mounting plate 1 arranged below the rewinding machine. The mounting plate 1 has an unwinding roller 5 and a take-up roller 4. A slitting assembly 7 is provided between the unwinding roller 5 and the take-up roller 4. Multiple guide rollers 6 are rotatably mounted on the mounting plate 1 between the slitting assembly 7 and the unwinding roller 5 and the take-up roller 4. The slitting assembly 7 includes a support base 19, a knife holder slide 18, a bottom knife shaft 10, a top knife shaft 9, a slider 8, and a top knife 3. The support base 19 is mounted on the mounting plate 1. Knife holder slides 18 are provided on both sides of the support base 19. The bottom knife shaft 10 is rotatably mounted on the lower end of the knife holder slide 18 through fixing blocks 14 at both ends. The top knife shaft 9 is rotatably mounted on the slider 8 at both ends. The slider 8 is slidably mounted on the upper end of the knife holder slide 18. An adjustment assembly 2 is provided between the slider 8 and the knife holder slide 18. A top knife 3 for cutting gold cardstock is installed at both ends of the top knife shaft 9. The paper is placed on the unwinding roller 5 and wound up by the winding roller 4. It passes through multiple guide rollers 6 and slitting components 7. The distance between the two end blades 3 is adjusted according to the required size of the gold card paper. By turning the knob 21, the threaded rod 22 is driven, which drives the slider 8 to move downward, so that the end blades 3 press the gold card paper together. The winding is achieved by the external motor driving the winding roller 4. During the winding process, the end blades 3 cut the loose edges of the gold card paper. The cut gold card paper meets the standard and can be used without being scrapped, which can save some materials and reduce consumption. By setting the threaded sleeve 16 and the matching blade ring block 17, when it is necessary to cut gold card paper of other specifications, multiple matching blade ring blocks 17 can be added to the threaded sleeve 16 to form the entry groove 13 with different distances, so as to meet the needs of multiple sizes. It has the characteristics of being easy to use and having a wide range of applications.

[0023] Specifically, a bottom knife 20 is sleeved on the bottom knife shaft 10. The bottom knife 20 has inlet grooves 13 at both ends that are adapted to the face knife 3. The face knife 3 cooperates with the inlet grooves 13 to achieve precise cutting during the pulling of the gold card paper, ensuring the integrity of the cut edge.

[0024] Preferably, one end of the bottom blade 20 is provided with a threaded sleeve 16, and the threaded sleeve 16 is provided with an adapter blade ring block 17. When it is necessary to cut gold card paper of other specifications, multiple adapter blade ring blocks 17 can be added to the threaded sleeve 16 to form blade inlet grooves 13 at different distances, thereby meeting the needs of multiple sizes.

[0025] Furthermore, the bottom cutter shaft 10 is provided with a first gear 12, and the face cutter shaft 9 is provided with a second gear 11. The first gear 12 and the second gear 11 mesh with each other, so that the bottom cutter shaft 10 and the face cutter shaft 9 can rotate synchronously to ensure the consistency of cutting.

[0026] Furthermore, the adjustment component 2 includes a threaded rod 22 and a knob 21. One end of the threaded rod 22 is rotatably connected to the upper part of the blade holder slide 18, and the lower end of the threaded rod 22 is threadedly connected to the slider 8. The knob 21 is installed on the top of the threaded rod 22. By rotating the knob 21, the threaded rod 22 is driven, which in turn drives the slider 8 to move downward, so that the face blades 3 at both ends press against the gold card paper, thereby achieving cutting.

[0027] Furthermore, both the slider 8 and the fixed block 14 are provided with mounting holes, and bearings 15 are provided in the mounting holes. The two ends of the bottom blade shaft 10 are rotatably mounted on the fixed block 14 through the bearings 15, and the two ends of the face blade shaft 9 are rotatably mounted on the slider 8 through the bearings 15. The rotatable connection through the bearings 15 ensures that the bottom blade shaft 10 and the face blade shaft 9 rotate more smoothly, resulting in better cutting continuity.

[0028] Furthermore, the face knife 3 includes a knife sleeve 31, a cutter 33, and a compression spring ring 32. The knife sleeve 31 is sleeved on the face knife shaft 9, and an inclined groove 34 is provided on the knife sleeve 31. The cutter 33 is sleeved on the inclined groove 34, and the compression spring ring 32 is sleeved on the inclined groove 34 on one side of the cutter 33. The compression spring ring 32 is in the inclined groove 34. Under the action of the inclined angle, the compression spring ring 32 presses the cutter 33 tightly, so that the cutter 33 can always be in contact with the side of the cutter groove 13, ensuring that elastic cutting can be achieved and avoiding easy damage to the cutter 33.

[0029] In this embodiment, the slitting device of a rewinder is used by placing a gold cardboard reel with a loose edge on the unwinding roller 5 and winding it up using the take-up roller 4. The rewinder passes through multiple guide rollers 6 and slitting components 7. The distance between the two end blades 3 is adjusted according to the required size of the gold cardboard. By rotating the knob 21, the threaded rod 22 is driven, which in turn drives the slider 8 to move downward, so that the two end blades 3 press the gold cardboard together. The winding is achieved with the take-up roller 4 driven by an external motor. During the winding process, the two end blades 3 cut the loose edge of the gold cardboard. The cut gold cardboard meets the standard and can be used without being scrapped, which can save some materials and reduce consumption. By setting the threaded sleeve 16 and the matching blade ring block 17, when it is necessary to cut gold cardboard of other sizes, multiple matching blade ring blocks 17 can be added to the threaded sleeve 16 to form the entry groove 13 with different distances, thereby meeting the needs of multiple sizes. This utility model discloses a slitting device for a rewinding machine used in surveying engineering. It can cut large-format gold cardstock with loose edges, allowing the gold cardstock to be reused. This can save some materials and reduce consumption. It has the characteristics of wide applicability and strong practicality.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
