Description

Technical Field

[0001] This utility model relates to a slitting machine, and more particularly to a double-layer turning and overlapping device for a slitting machine. Background Technology

[0002] Chinese utility patent CN216736862U discloses a double-layer slitting, turning, overlapping, positioning, and cutting machine. The double-layer wide thin paper is first automatically aligned, then slit in the same way, and then the upper and lower layers are turned 90° by 45° turning rollers respectively, and then positioned and overlapped. Cutting is performed by identification, realizing the connection and slitting of the two layers of thin paper. However, the wax surface of the upper layer of paper will be scratched when it turns by the turning rollers. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a double-layer turning and overlapping device for a slitting machine, wherein the first inclined roller is located below the first tensioning roller group, and the printing surface of the first material strip facing upward contacts the first inclined roller to turn.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The double-layer turning and overlapping device of the slitting machine includes a frame, on which a first reversing mechanism, a second reversing mechanism and an overlapping roller group are provided. The first reversing mechanism is located above the second reversing mechanism. A first material strip passing through the first reversing mechanism and a second material strip passing through the second reversing mechanism overlap at the overlapping roller group. The first reversing mechanism includes a first inclined roller and a first tensioning roller group. The second reversing mechanism includes a second inclined roller and a second tensioning roller group. The second tensioning roller group is located above the second inclined roller. The device also includes a guide roller group, which connects the overlapping roller group and the first tensioning roller group. The guide roller group is located above the overlapping roller group, and the first tensioning roller group is located above the first inclined roller.

[0005] In this scheme, the conveyed material strips are all printed with the printing side facing up and the wax side facing down. The first tensioning roller group is located above the first inclined roller, so that the printing side of the first material strip contacts the first inclined roller to turn. The guide roller group guides the first material strip downward and overlaps it with the second material strip at the overlapping roller group.

[0006] Preferably, the overlapping roller group includes a cooperating upper support roller and a lower support roller, and the plurality of first reversing mechanisms and the plurality of second reversing mechanisms are arranged longitudinally.

[0007] In this scheme, the upper support roller and the lower support roller work together to make the multiple layers of material strip overlap together.

[0008] Preferably, the second reversing mechanism includes a second discharge guide roller, which is flush with the lower support roller in the vertical direction, and the first inclined roller is higher than the overlapping roller group.

[0009] In this scheme, the second material belt is conveyed horizontally after passing through the second discharge guide roller, and the second discharge guide roller will participate in supporting the overlapping second material belt.

[0010] Preferably, the first reversing mechanism includes a first discharge guide roller, the guide roller group includes a reversing roller, the reversing roller and the first discharge guide roller are each corresponding to the upper support roller, the first material strip passes through the first discharge guide roller, the reversing roller and the upper support roller in sequence and the winding path is L-shaped, and the upper support roller is more than the lower support roller.

[0011] In this scheme, multiple first material strips overlap sequentially with the second material strips that overlap earlier, avoiding uneven tension when multiple first material strips overlap at the reversing roller and are guided downwards.

[0012] Preferably, the guide roller assembly further includes a guide tension roller, which connects the reversing roller and the first discharge guide roller.

[0013] In this scheme, the tensioning roller tensions the first material strip with a large gap between the reversing roller and the first discharge guide roller, so that the tension of multiple first material strips is uniform.

[0014] Preferably, both the first tensioning roller group and the second tensioning roller group include a fixed roller and an adjusting roller, wherein the adjusting roller is configured to be raised and lowered.

[0015] In this scheme, the lifting and adjusting roller controls the tension of the material belt.

[0016] Preferably, both the first inclined roller and the second inclined roller are provided with air blowing holes.

[0017] In this design, the gas blown out of the air vents prevents the printed surface from contacting the surface of the inclined roller, thus reducing friction.

[0018] Preferably, the frame has an opening for the first material belt to pass through, and the first inclined roller is disposed at the opening.

[0019] In this scheme, the first material strip passes through the opening and wraps around the first inclined roller, and the operator can directly observe the first reversing mechanism and the second reversing mechanism.

[0020] Preferably, the adjusting roller is mounted on a mounting base, the mounting base is connected to a slider and a height indicator, the frame is provided with a slide rail that cooperates with the slider, the height indicator is equipped with a scale, and the mounting base is threaded with an adjusting rod.

[0021] In this design, the height indicator points to the scale on the ruler, enabling quantitative adjustment.

[0022] The beneficial effects of this utility model are as follows: the first tensioning roller group is located above the first inclined roller, so that the printing surface of the first material strip contacts the first inclined roller and changes direction; the guide roller group guides the first material strip downward and overlaps it with the second material strip at the overlapping roller group; the second material strip is conveyed horizontally after passing through the second discharge guide roller, and the second discharge guide roller participates in supporting the overlapping second material strip; multiple first material strips overlap with the previously overlapped second material strips in sequence, avoiding uneven tension when multiple first material strips overlap and are guided downward at the reversing roller. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description

[0030] See appendix Figure 1-2 In this embodiment, a double-layer turning and overlapping device for a slitting machine includes a frame 1. The frame 1 is provided with a first reversing mechanism 2, a second reversing mechanism 3, and an overlapping roller group 4. The first reversing mechanism 2 is located above the second reversing mechanism 3. A first material strip passing through the first reversing mechanism 2 and a second material strip passing through the second reversing mechanism 3 overlap at the overlapping roller group 4. The first reversing mechanism 2 includes a first inclined roller 5 and a first tensioning roller group 6. The second reversing mechanism 3 includes a second inclined roller 24 and a second tensioning roller group 25. The second tensioning roller group 25 is located above the second inclined roller 24. Both the first inclined roller 5 and the second inclined roller 24 are provided with air blowing holes 16. The frame 1 is provided with an opening for the first material strip to pass through, and the first inclined roller 5 is disposed at the opening.

[0031] The system also includes a guide roller group 7, which connects the overlapping roller group 4 and the first tension roller group 6. The guide roller group 7 is located above the overlapping roller group 4, and the first tension roller group 6 is located above the first inclined roller 5. The overlapping roller group 4 includes a cooperating upper support roller 8 and a lower support roller 9. Multiple first reversing mechanisms 2 and multiple second reversing mechanisms 3 are arranged longitudinally. The second reversing mechanism 3 includes a second discharge guide roller 10, which is flush with the lower support roller 9 in the vertical direction. The first inclined roller 5 is higher than the overlapping roller group 4.

[0032] The first reversing mechanism 2 includes a first discharge guide roller 11, and the guide roller group 7 includes a reversing roller 12 and a guide tension roller 13. The reversing roller 12 and the first discharge guide roller 11 are each corresponding to the upper support roller 8. The first material strip passes through the first discharge guide roller 11, the reversing roller 12 and the upper support roller 8 in sequence, and the winding path is L-shaped. The upper support roller 8 is longer than the lower support roller 9. The guide tension roller 13 connects the reversing roller 12 and the first discharge guide roller 11.

[0033] In this embodiment, the two wide strips unwound from the two sets of material rolls are simultaneously cut to form two layers of multiple narrow strips (first strip and second strip). The first strip passes through the opening and is folded 45 degrees at the first inclined roller 5 (the conveying direction changes from transverse to longitudinal). After being tensioned by the first tensioning roller group 6, it passes sequentially through the first discharge guide roller 11 and the reversing roller 12, and merges into the overlapping multi-layered strips at the overlapping roller group 4. The second strip is folded 45 degrees at the second inclined roller 24 at the bottom of the frame 1, tensioned by the second tensioning roller group 25, and then conveyed to the overlapping roller group 4. The strip is first overlapped at the second discharge guide roller 10, and the multi-layered strip after overlap by the overlapping roller group 4 is then cut and stretched. The tensioning roller group includes a feed guide roller and an inclined roller located between the overlapping roller group 4 and the feed roller group. The strip is in the shape of a c, so that the printing surface that was facing down after the turn flips back to face up. The strip is serpentine at the tensioning roller group and is fully tensioned. The inclined roller is connected to the frame 1 through a mounting block. The mounting block has a notch for adjacent inclined rollers to be inserted. The adjacent mounting blocks cooperate to radially limit the inclined rollers between them. The air blown out by the air holes 16 on the inclined roller can support the strip.

[0034] In other alternative embodiments, the first reversing mechanism 2 can refer to the second reversing mechanism 3. The first strip is first overlapped, then guided downward after passing through the reversing roller 12, and the overlapping multi-layer strips are merged at the upper support roller 8. The tension of each first strip needs to be adjusted.

[0035] See appendix Figure 2 The first tensioning roller group 6 and the second tensioning roller group 25 both include a fixed roller 14 and an adjusting roller 15. The adjusting roller 15 is mounted on a mounting base 18. The mounting base 18 is connected to a slider 19 and a height indicator 20. The frame 1 is provided with a slide rail 21 that cooperates with the slider 19. The height indicator 20 is equipped with a scale 22. The mounting base 18 is threaded with an adjusting rod.

[0036] In this embodiment, the adjusting rod is connected to a rotating shaft via a helical gear meshing transmission. The rotating shaft is connected to a handwheel. Rotating the handwheel can adjust the height of the adjusting roller 15. A locking component is provided on the mounting base 18. The locking component includes a handle. Pulling the handle can lock or release the mounting base 18.

[0037] The above description represents the preferred embodiment of this utility model. It should be noted that the scope of protection of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these can also be considered as part of the scope of protection of this utility model.
