Then it is fed into the next process by a feeder. There are problems such as uneven edges of the paper during transportation and storage, and curling of the stacked paper. Before it is put into the machine, the paper needs to be leveled and the four sides aligned manually, which is time-consuming and labor-intensive.

[0004] CN216230943U - A paper bag machine dual feeder feeding mechanism is disclosed. The two feeder heads can simultaneously pick up two sheets of paper.

At the same time, under the action of the lifting mechanism, the feeder heads can be easily adjusted up and down, which can better pick up paper. However, it cannot solve the above-mentioned technical problems. Utility Model Content

[0060] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0061] See Figures 1-16 A roll slitting machine comprises: a frame, on which are sequentially arranged: an upper winding mechanism for supporting the roll; a floating roller for conveying paper; a leveling mechanism for leveling the paper; an unfolding mechanism for unfolding the paper; a slitting mechanism for cutting the paper; and a paper output mechanism for outputting the paper.

[0062] The winding mechanism 17 is existing technology and is a support frame that can support the roll material.

[0063] The leveling mechanism includes: a frame 1; a leveling conveyor roller 191, rotatably mounted on the frame 1; and an integral leveling mechanism 192, mounted on the frame 1, which can level the curvature of the paper. By using the integral leveling mechanism 192 to reverse-press the curved paper, the curled paper can be straightened before the paper cutting process, making it easier for subsequent processing.

[0064] The overall leveling mechanism 192 includes: a leveling frame 1921, rotatably mounted on the frame 1; a leveling rod, mounted on the leveling frame 1921, the end face of which can squeeze the paper; and a leveling drive mechanism, mounted on the leveling frame 1921, capable of driving the leveling frame 1921 to swing. By driving the leveling frame 1921 to swing through the leveling drive mechanism, the end face of the leveling rod on the leveling frame 1921 squeezes the paper, applying reverse pressure to the curved paper. This straightens the curled paper before the paper cutting process, facilitating subsequent processing.

[0065] The leveling rods include a first leveling rod 1922 and a second leveling rod 1923, through which paper can pass. The first leveling rod 1922 and the second leveling rod 1923 can respectively press both sides of the paper, accommodating the leveling needs of paper with different curvature directions. For example, assuming the paper is curled inwards, the first leveling rod 1922 presses the paper, applying reverse pressure to the curved paper; assuming the paper is curled outwards, the second leveling rod 1923 presses the paper, applying reverse pressure to the curved paper (here, left and right directions are just hypothetical examples, meaning the two leveling rods apply reverse pressure to paper with different curvature directions).

[0066] Both the first leveling bar 1922 and the second leveling bar 1923 are equipped with an integral leveling plane 1924, which can compress the paper. The integral leveling plane 1924 compresses the paper as a whole, applying reverse compression to curved paper. This straightens the curled paper before the paper cutting process, facilitating subsequent processing. The integral leveling plane 1924 has a single, pointed edge.

[0067] The leveling drive mechanism is a leveling motor 1925, which drives the leveling frame 1921 to swing. By driving the leveling frame 1921 to swing, the leveling motor 1925 selects either the first leveling rod 1922 or the second leveling rod 1923 to press the paper. The degree of swing can also adapt to the leveling requirements of paper with different degrees of curvature. The leveling drive mechanism can also be configured as other conventional drive mechanisms in this field.

[0068] It also features a left and right leveling mechanism 193, which can level the difference in curvature between the left and right sides of the paper. The left and right leveling mechanism 193 can adjust the position of the left and right sides to meet the leveling needs of different curvatures on both sides of the paper.

[0069] The left and right leveling mechanism 193 has a left second leveling rod 19231931, which can squeeze the paper; both ends of the left second leveling rod 19231931 are mounted on the frame 1 through the left and right adjustment mechanism 1932. The left second leveling rod 19231931 can be adjusted left and right to adjust the position of the left and right sides to meet the leveling requirements of different curvatures on both sides of the paper.

[0070] The left-right adjustment mechanism 1932 has an adjustment frame 1933, which is mounted on the frame 1. An adjustment slider 1934 is slidably mounted on the adjustment frame 1933, and both ends of the left second leveling rod 19231931 are mounted on the adjustment slider 1934. By adjusting the slider 1934, the left-right position of the left second leveling rod 19231931 can be changed to correspond to the leveling requirements of different degrees of curvature on both sides of the paper. The left-right adjustment mechanism 1932 can also be configured as other conventional drive mechanisms in the art, such as adjustment screws.

[0071] An adjusting screw 1935 is also provided, which is threadedly connected to the adjusting slider 1934; an adjusting handwheel 1936 is provided at the end of the adjusting screw 1935. By rotating the adjusting screw 1935, the position of the adjusting slider 1934 is changed, and by adjusting the slider 1934, the left and right positions of the second left leveling rods 1923 and 1931 are changed, which corresponds to the leveling requirements of different degrees of curvature on both sides of the paper.

[0072] The paper is straightened by scraping the curved side of the paper with the edges of the leveling bar. The swing angle of the swing arm can be controlled by the rotation of the rotating roller, so that the scraping degree of the edges of the leveling bar varies to match different types of paper curvature. At the same time, a hand-cranked scraping bar is added between them to assist in pulling the paper according to the different tensions on the left and right sides of the paper.

[0073] It can straighten curled paper before the paper cutting process, making it easier for subsequent processing.

[0074] The unfolding mechanism includes: a frame 16; an unfolding roller 201 and a traction roller 202, mounted on the frame 16, which cooperate to transport paper; and spiral grooves 2011, on which the unfolding roller 201 has spiral grooves 2011 extending from near the center to both sides, with the spiral grooves 2011 on both sides of the unfolding roller 201 rotating in opposite directions. During rotation, the spiral grooves 2011 on the unfolding roller 201 diffuse from the center to both sides, in the same direction as the paper's movement. As the paper moves forward, the spiral groove structure applies tension to stretch the paper to both sides, allowing it to pass through the unfolding traction roller 202 without wrinkles.

[0075] The stretching roller 201 is movably mounted on the frame 16 via the pressing mechanism 204. The pressing mechanism 204 can press the stretching roller 201 onto the traction roller 202, and the paper is conveyed by the cooperation of the stretching roller 201 and the traction roller 202.

[0076] The pressing mechanism 204 includes a swing block 203, an expansion roller 201 rotatably mounted near the middle of the swing block 203, and a first end of the swing block 203 rotatably mounted on the frame 16. A pressing power device is provided at the second end of the swing block 203. The second end of the swing block 203 is pressed by the pressing power device, and the swing block 203 swings about the first end of the swing block 203 as the pivot, so that the expansion roller 201 and the traction roller 202 cooperate to press the paper.

[0077] The clamping power device is a clamping cylinder, which is mounted on the frame 16. The piston rod of the clamping cylinder is equipped with a pressure rod 20442043 that clamps the second end of the swing block 203. The clamping cylinder clamps the second end of the swing block 203. Other conventional clamping methods in the art can also be used, such as pressure blocks, hydraulic cylinders, etc.

[0078] The pressing mechanism 204 also includes a lifting mechanism, which includes a support block 2041 mounted on the frame 16. A support spring 2042 is provided on the support block 2041, and the support spring 2042 contacts the second end of the swing block 203. The support spring 2042 of the lifting mechanism supports the swing block 203. After the pressing cylinder releases its pressure, the support spring 2042 can also lift the swing block 203, increasing the distance between the spreading roller 201 and the traction roller 202, facilitating paper adjustment.

[0079] The support spring 2042 is located below the second end of the swing block 203; the pressure rod 20442043 is located above the second end of the swing block 203. The support spring 2042 supports the swing block 203 below, and the pressure rod 20442043 presses the swing block 203 above.

[0080] The traction roller 202 is rotatably mounted on the frame 16 and is connected to the power unit. The power unit can be a conventional means such as a belt mechanism, gear mechanism, or servo motor.

[0081] The lower traction roller is an iron roller that controls the traction speed, while the upper traction roller is a rubber roller with spiral grooves that spread outwards from the center to both sides, in the same direction as the paper's forward movement. As the paper moves forward, the spiral groove structure applies tension to both sides, allowing the paper to pass through the stretching traction roller without wrinkles.

[0082] It can apply tension to both sides of the paper as it moves forward, so that the paper can be stretched and pulled without wrinkles.

[0083] The slitting mechanism comprises: an upper cutting blade fixing shaft 1, rotatably mounted on the frame; a lower blade holder shaft 7, rotatably mounted on the frame; a toothed blade mounting mechanism, mounted on the upper cutting blade fixing shaft 1 and the lower blade holder shaft 7, capable of mounting an upper toothed blade 14; and a flat blade mounting mechanism, mounted on the upper cutting blade fixing shaft 1, capable of mounting an upper flat blade. This is a slitting technology for cutting roll materials into sheets using both flat and toothed cutting methods. During flat cutting, there is no need to adjust the gap between the upper and lower blades, and it can cut directly on the lower blade shaft or the lower blade holder, making it simple and convenient to use.

[0084] The toothed cutter mounting mechanism includes: an upper cutter fixing seat 2, mounted on an upper cutter fixing shaft 1; an upper cutter pressure plate 4, detachably connected to the upper cutter fixing seat 2; an upper toothed cutter 14, clamped between the upper cutter fixing seat 2 and the upper cutter pressure plate 4; a clamping mechanism capable of clamping the upper cutter pressure plate 4 and the upper cutter fixing seat 2; and a lower toothed cutter seat 15, mounted on a lower cutter seat shaft 7, which is compatible with the upper toothed cutter 14. The clamping mechanism is a pressure plate tightening screw 6, which is threadedly connected to the upper cutter fixing seat 2, serving a clamping and fixing function. The upper cutter fixing seat 2 has a stop edge that limits the end of the upper toothed cutter 14, serving a limiting function. The lower toothed cutter seat 15 has a lower groove 151 that is compatible with the upper toothed cutter 14. When installing the toothed blade, the upper toothed blade 14 is clamped and fixed by the upper cutter fixing seat 2 and the upper cutter pressure plate 4. The upper cutter pressure plate 4 is provided with screw holes. By tightening the pressure plate screw 6 out of the screw holes of the upper cutter pressure plate 4, the upper cutter fixing shaft 1's groove edge and the upper cutter pressure plate 4 are locked, thereby clamping the upper toothed blade 14. The lower blade holder shaft 7 is rotated to align the upper toothed blade 14 and the lower toothed blade holder 15, so that the upper toothed blade 14 can be inserted into the lower groove 151 of the lower toothed blade holder 15. Then the upper cutter gear 9 and the lower cutter gear 11 are locked. The upper and lower cutter shafts are driven to rotate and cut the roll material through the power input synchronous pulley 13.

[0085] The flat blade mounting mechanism includes: an upper cutting blade spring plate 5, mounted on the upper cutting blade fixing seat 2; an upper flat blade, clamped between the upper cutting blade fixing seat 2 and the upper cutting blade pressure plate 4; the end of the upper flat blade is in contact with the upper cutting blade spring plate 5; and the cutting edge of the upper flat blade can be adapted to the outer circumferential surface of the lower blade seat shaft 7. When installing the flat blade, the upper flat blade is also clamped and fixed by the upper cutting blade fixing seat 2 and the upper cutting blade pressure plate 4. When installing the upper flat blade, the bottom of the upper flat blade is aligned with the upper cutting blade spring plate 5. Then, the pressure plate tightening screw 6 is adjusted so that the groove edge of the upper cutting blade fixing shaft 1 and the upper cutting blade pressure plate 4 give the upper flat blade a pre-tightening force. Then, the upper and lower cutting blade shafts are rotated so that the upper flat blade cuts on the lower blade seat shaft 7. At this time, since the clamping force is the pre-tightening force, it cannot lock the upper flat blade. The upper flat blade will be squeezed inward by the lower blade seat shaft 7. Since the bottom of the upper flat blade is aligned with the upper cutting blade spring plate 5, the upper cutting blade spring plate 5 will be deformed, giving the upper flat blade a rebound force, so that the upper flat blade presses on the lower blade seat shaft 7, and the left and right sides are consistent during cutting. Then, the screw is tightened to lock the upper flat blade, and the upper flat blade adjustment is completed.

[0086] The back of the upper cutter fixing seat 2 is provided with a mounting groove, and the upper cutter spring sheet 5 is installed in the mounting groove, which facilitates the installation of the upper cutter spring sheet 5 and can accommodate the deformation of the upper cutter spring sheet 5.

[0087] The back of the upper cutter fixing seat 2 is provided with a clearance groove to avoid the blocking edge, which plays a clearance role and can ensure that the upper cutter fixing seat 2 and the upper cutter pressure plate 4 can clamp and fix the cutter from the left and right.

[0088] The upper cutter fixing shaft 1 and the lower cutter holder shaft 7 are rotatably mounted on the frame via bearing seats 12; an upper cutter gear 9 is fixedly mounted on the upper cutter fixing shaft 1, and a lower cutter gear 11 is fixedly mounted on the lower cutter holder shaft 7, with the cutter gear and the lower cutter gear 11 meshing together. This serves as a power drive.

[0089] 1. Roll material can be cut into sheets using both flat and toothed blades. The same set of equipment can be used to meet both straight and serrated edge requirements by changing the blades. 2. When using the flat blade, you can choose to cut on the lower blade holder 7 or the lower toothed blade holder 15. Compared to the toothed blade, it allows for direct cutting without aligning the upper and lower blades.

[0090] The above-described method of using the roll material cutting device involves installing the toothed blades. The upper toothed blade 14 is clamped and fixed by the upper cutter fixing seat 2 and the upper cutter pressure plate 4. The upper cutter pressure plate 4 has screw holes. By tightening the pressure plate screws 6 out of the screw holes in the upper cutter pressure plate 4, the upper cutter fixing shaft 1's groove edge and the upper cutter pressure plate 4 are locked together, thus clamping the upper toothed blade 14. The lower cutter seat shaft 7 is rotated to align the upper toothed blade 14 and the lower toothed blade seat 15, allowing the upper toothed blade 14 to insert into the lower groove 151 of the lower toothed blade seat 15. Then, the upper cutter gear 9 and the lower cutter gear 11 are locked. The power input synchronous wheel 13 drives the upper and lower cutter shafts to rotate and cut the roll material.

[0091] When installing the flat blade, the upper flat blade is also clamped and fixed by the upper cutting blade fixing seat 2 and the upper cutting blade pressure plate 4. When installing the upper flat blade, the bottom of the upper flat blade is aligned with the upper cutting blade spring plate 5. Then, the pressure plate tightening screw 6 is adjusted so that the groove edge of the upper cutting blade fixing shaft 1 and the upper cutting blade pressure plate 4 give the upper flat blade a pre-tightening force. Then, the upper and lower cutting blade shafts are rotated so that the upper flat blade cuts on the lower blade seat shaft 7. At this time, since the clamping force is the pre-tightening force, it cannot lock the upper flat blade. The upper flat blade will be squeezed inward by the lower blade seat shaft 7. Since the bottom of the upper flat blade is aligned with the upper cutting blade spring plate 5, the upper cutting blade spring plate 5 will be deformed, giving the upper flat blade a rebound force, so that the upper flat blade presses on the lower blade seat shaft 7, and the left and right sides are consistent during cutting. Then, the screw is tightened to lock the upper flat blade, and the upper flat blade adjustment is completed.

[0092] It is a slitting technology that can cut rolls into sheets using both flat cutting and toothed cutting. When cutting flat, there is no need to adjust the gap between the upper and lower blades, and it can cut directly on the lower blade shaft or on the lower blade holder, making it simple and convenient to use.

[0093] This is a slitting technology that can cut rolls into sheets using both flat and toothed cutting methods. Because flat cutting doesn't require adjusting the gap between the upper and lower blades, and can cut directly on either the lower blade shaft or the lower blade holder, it is convenient and simple to use. Furthermore, during cutting, the entire blade cuts directly onto the roll without any asynchrony between the left and right sides, producing a neat rectangular cut. To achieve a toothed cut, simply replace the upper toothed blade and the lower toothed blade holder, aligning the grooves of the upper blade and the lower blade holder. For an even simpler method, first align the upper toothed blade with the upper and lower blade holders, then lock the phase of the upper and lower cutting shafts. When switching to a flat blade, the flat blade cuts on the flat blade holder. When switching to a toothed blade, because the grooves of the toothed blade and the toothed blade holder were aligned the first time, there is no need for further blade alignment, and it can be used directly. The entire mechanism only requires one blade alignment for seamless switching between flat and toothed blades.

[0094] The paper output mechanism 24 is capable of outputting paper. The paper output mechanism 24 is a series of conveying rollers capable of outputting paper.

[0095] With the above structure, the roll material can be flattened without curling or wrinkling by the leveling and stretching mechanism. The flat material is then cut into flat sheets. The roll material can be cut into sheets using both flat and serrated blades. The same set of equipment can be used to meet the requirements of both straight and serrated edges of the sheet by changing the blades with different cutting edges.
