Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and in particular to a rewinding and slitting machine for cardboard processing. Background Technology

[0002] Paperboard is a thick paper made by pressing multiple layers of pulp together. It is usually used to make packaging materials, paper boxes, cardboard cartons, etc. Since paperboard and paper are usually recyclable materials, slitting machines are also used to cut the paper during paperboard processing, and the cut paper is used as material for paperboard processing.

[0003] When using a slitting machine to cut paper, one end of the paper is passed through the traction roller of the slitting machine and wound onto the take-up roller. The traction roller drives the paper to move past the cutting blade to be cut into the raw material used for paperboard processing. Between the time the paper enters the traction roller, the position of the moving paper may be skewed, causing wrinkles on the paper surface. This can lead to deviations in the angle and position of the cutting blade when cutting the paper, resulting in poor slitting effect. Utility Model Content

[0004] The purpose of this invention is to address the problem that the paper may become misaligned as it enters the traction rollers, causing wrinkles on the paper surface and resulting in deviations in the angle and position of the cutting blade when cutting the paper, leading to poor slitting results. This invention provides a rewinding and slitting machine for cardboard processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rewinding and slitting machine for cardboard processing, comprising a frame, an unwinding roller disposed on the outer surface of the frame, a directional roller rotatably connected to the outer surface of the frame, a traction roller and a cutting roller rotatably disposed on the outer surface of the frame, a plurality of cutting blades disposed on the outer surface of the cutting roller, a take-up roller disposed on one side of the frame, and a positioning device disposed on the outer surface of the frame, the positioning device comprising two grooved rods, the two grooved rods being disposed on the outer surface of the frame by means of a convenient device, a sliding rod being slidably connected to the inner wall of the grooved rods, a rectangular rod being fixedly connected to the side of the two sliding rods that are close to each other, a top rod being fixedly connected to the top of the rectangular rod, the top edge of the top rod being arc-shaped, a pressure roller being rotatably connected to one side of the sliding rod, a screw being fixedly connected to one side of the sliding rod, the outer surface of the screw sliding on the inner wall of the grooved rod, and a threaded ring being threadedly connected to the outer surface of the screw.

[0006] The effect achieved by the above components is as follows: By setting the pressure roller, when using the slitting machine, the two grooved rods are fixed to one side of the frame with the help of a convenient device. The bracket on the side of the unwinding roller is moved to roll the paper material onto the unwinding roller. The bracket is moved again to support the unwinding roller. Then, one end of the paper is passed through the directional roller and traction roller on the outer surface of the frame and fixed to the surface of the take-up roller. The sliding rod is pushed up and down at the two grooved rods to adjust the height of the sliding rod and the pressure roller, so that the outer surface of the pressure roller contacts the paper surface located between the top rod and the pressure roller. Then, the threaded ring is rotated to move the threaded ring on the outer surface of the screw to press one side against the outer surface of the grooved rod and fix it to the position of the sliding rod. When the paper moves, it will move between the pressure roller and the top rod. The pressure roller and the top rod limit the position of the paper when it moves, so as to avoid the problem of the paper's position being deviated during movement, which would cause wrinkles on the surface and affect the slitting effect.

[0007] Preferably, the outer surface of the pressure roller is fixedly connected with a raised strip, which is a curved rubber strip.

[0008] The effect achieved by the above components is that when the paper moves between the pressure roller and the top rod, the curved rubber strips can further pull the two sides of the paper outward, thus further preventing wrinkles from appearing on the paper surface.

[0009] Preferably, a plurality of protrusions are fixedly connected to the outer surface of the threaded ring, and the protrusions are circumferentially distributed on the outer surface of the threaded ring.

[0010] The effect achieved by the above components is that by pressing the protrusion on the outer surface of the threaded ring with your hand, it is easier to push the threaded ring to rotate and it is less likely to slip.

[0011] Preferably, a stop block is fixedly connected to one end of the screw, and the length of the stop block is greater than the diameter of the screw.

[0012] The effect achieved by the above components is that by setting the stop, the range of movement of the threaded ring on the outer surface of the screw can be limited, so as to avoid the threaded ring from falling off the screw surface when it moves away from the sliding rod.

[0013] Preferably, a gasket is fixedly connected to one side of the threaded ring, and the gasket is made of rubber.

[0014] The effect achieved by the above components is that when the side of the threaded ring with the rubber gasket is pressed against the outer surface of the grooved rod, the pressure is more tight, and the position of the sliding rod is more stably fixed.

[0015] Preferably, the convenient device includes two L-shaped plates, one end of which is fixedly connected to one end of the groove rod. The outer surface of the L-shaped plates is provided with several through holes. Slots are provided on both sides of the outer surface of the frame. Bolts are threadedly connected to the outer surface of the frame near the slots.

[0016] The effect achieved by the above components is as follows: When installing the positioning device, insert one end of the L-shaped plate at one end of the two groove rods into the slots on both sides of the outer surface of the frame, so that the end of the L-shaped plate with the through hole is located in the slot. Then, use bolts to pass through the outer surface of the frame and insert into the slot and the through hole on the outer surface of the L-shaped plate to fix the position of the L-shaped plate in the slot. Install the L-shaped plate and the positioning device on the outer surface of the frame. When the positioning device is not needed, rotate the bolts to disengage the bolts from the slot and the through hole on the outer surface of the L-shaped plate, and then remove the L-shaped plate and the positioning device.

[0017] Preferably, a plurality of elastic ropes are fixedly connected to the outer surface of the frame, and the end of the elastic rope away from the frame is fixedly connected to one end of a bolt.

[0018] The effect achieved by the above components is that by setting elastic ropes, the bolts can always be fixed to one side of the frame, making it easy to retrieve the bolts when installing the positioning device and avoiding the loss of the bolts.

[0019] Preferably, a support rod is fixedly connected to the bottom end of the L-shaped plate, and the support rod and the L-shaped plate form a certain oblique angle.

[0020] The effect achieved by the above components is that after one end of the L-shaped plate is inserted into the slot on the outer surface of the frame, one end of the support rod will abut against the outer surface of the frame to support the bottom of the L-shaped plate, thereby improving the stability of installing the positioning device on the outer surface of the frame through the convenient device.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a positioning device, when using the slitting machine, the outer surface of the pressure roller contacts the surface of the paper located between the top rod and the pressure roller. When the paper moves, it will move between the pressure roller and the top rod. The rotating pressure roller and the top rod restrict the position of the paper during movement, so as to avoid the problem of the paper's position being skewed during movement, which would cause wrinkles on the surface and affect the slitting effect.

[0029] Example 1, as Figure 1-5 As shown, a rewinding and slitting machine for cardboard processing includes a frame 1. An unwinding roller 4 is mounted on the outer surface of the frame 1. A guiding roller 5 is rotatably connected to the outer surface of the frame 1. A traction roller 6 and a cutting roller 7 are rotatably mounted on the outer surface of the frame 1. Several cutting blades are mounted on the outer surface of the cutting roller 7. A take-up roller 8 is mounted on one side of the frame 1. A positioning device 2 is mounted on the outer surface of the frame 1. The positioning device 2 includes two grooved rods 21, which are mounted on the outer surface of the frame 1 by means of a convenient device 3. A sliding rod 22 is slidably connected to the inner wall of the grooved rods 21. A rectangular rod 23 is fixedly connected to the side of the two sliding rods 22 that are close to each other. A top rod 26 is fixedly connected to the top of the rectangular rod 23. The top edge of the top rod 26 is arc-shaped. A pressure roller 24 is rotatably connected to one side of the sliding rod 22. A screw 27 is fixedly connected to one side of the sliding rod 22. The outer surface of the screw 27 slides on the inner wall of the grooved rod 21. A threaded ring 28 is threadedly connected to the outer surface of the screw 27. The pressure roller 24... When using the slitting machine, the two grooved rods 21 are fixed to one side of the frame 1 with the help of the convenient device 3. The bracket on one side of the unwinding roller 4 is moved to roll the paper material onto the unwinding roller 4. The bracket is moved again to support the unwinding roller 4. Then, one end of the paper is passed through the directional roller 5 and traction roller 6 on the outer surface of the frame 1 and fixed to the surface of the take-up roller 8. The sliding rod 22 is pushed up and down at the two grooved rods 21 to adjust the height of the sliding rod 22 and the pressure roller 24 so that the outer surface of the pressure roller 24 contacts the paper surface located between the top rod 26 and the pressure roller 24. Then, the threaded ring 28 is rotated to move the threaded ring 28 on the outer surface of the screw 27 to press one side against the outer surface of the grooved rod 21 and fix it to the position of the sliding rod 22. When the paper moves, it will move between the pressure roller 24 and the top rod 26. The position of the paper during movement is restricted by the pressure roller 24 and the top rod 26 to avoid the problem of the paper's position being skewed during movement, which would cause wrinkles on the surface and affect the slitting effect.

[0030] Reference Figure 2 , Figure 4 and Figure 5 As shown in this embodiment: a raised strip 25 is fixedly connected to the outer surface of the pressure roller 24. The raised strip 25 is a curved rubber strip. When the paper moves between the pressure roller 24 and the top rod 26, the curved rubber raised strip 25 can further pull the two sides of the paper outward, further preventing wrinkles from appearing on the paper surface. Several protrusions 29 are fixedly connected to the outer surface of the threaded ring 28. The protrusions 29 are circumferentially distributed on the outer surface of the threaded ring 28. By pressing the protrusions 29 on the outer surface of the threaded ring 28 with your hand, you can more easily push the threaded ring 28 to rotate and it is not easy to slip.

[0031] Reference Figure 2 , Figure 4 and Figure 5 As shown in this embodiment: a stop 211 is fixedly connected to one end of the screw 27. The length of the stop 211 is greater than the diameter of the screw 27. By setting the stop 211, the movement range of the threaded ring 28 on the outer surface of the screw 27 can be limited, so as to avoid the threaded ring 28 from falling off the surface of the screw 27 when it moves away from the sliding rod 22. A washer 210 is fixedly connected to one side of the threaded ring 28. The washer 210 is made of rubber. When the side of the threaded ring 28 with the rubber washer 210 is pressed tightly against the outer surface of the groove rod 21, the position of the sliding rod 22 is fixed more stably.

[0032] Reference Figure 1-4 As shown in this embodiment: the convenient device 3 includes two L-shaped plates 32. One end of the L-shaped plate 32 is fixedly connected to one end of the groove rod 21. The outer surface of the L-shaped plate 32 is provided with several through holes 33. The outer surface of the frame 1 is provided with slots 31 on both sides. The outer surface of the frame 1 is threaded with bolts 34 on the side near the slots 31. When installing the positioning device 2, one end of the L-shaped plate 32 at one end of the two groove rods 21 is inserted into the slots 31 on both sides of the outer surface of the frame 1, so that the end of the L-shaped plate 32 with the through holes 33 is located in the slot 31. Then, the bolts 34 are inserted through the outer surface of the frame 1 into the slots 31 and into the through holes 33 on the outer surface of the L-shaped plate 32 to fix the position of the L-shaped plate 32 in the slots 31. The L-shaped plate 32 and the positioning device 2 are installed on the outer surface of the frame 1. When the positioning device 2 is not needed, the bolts 34 are rotated to disengage the bolts 34 from the slots 31 and the through holes 33 on the outer surface of the L-shaped plate 32. Then the L-shaped plate 32 and the positioning device 2 can be removed.

[0033] Reference Figure 1-4As shown in this embodiment: several elastic ropes 35 are fixedly connected to the outer surface of the frame 1. The end of the elastic rope 35 away from the frame 1 is fixedly connected to one end of the bolt 34. By setting the elastic ropes 35, the bolt 34 can always be fixed to one side of the frame 1, which is convenient for taking the bolt 34 when installing the positioning device 2 and avoids the bolt 34 being lost. The bottom end of the L-shaped plate 32 is fixedly connected to a support rod 36. The support rod 36 and the L-shaped plate 32 form a certain angle. After one end of the L-shaped plate 32 is inserted into the slot 31 on the outer surface of the frame 1, one end of the support rod 36 will abut against the outer surface of the frame 1 to support the bottom of the L-shaped plate 32 and improve the stability of installing the positioning device 2 on the outer surface of the frame 1 through the convenient device 3.

[0034] Working principle: When using the slitting machine, insert one end of the L-shaped plate 32 at one end of each of the two grooved rods 21 into the slots 31 on both sides of the outer surface of the frame 1, so that the end of the L-shaped plate 32 with the through hole 33 is located in the slot 31. Then, use bolts 34 to pass through the outer surface of the frame 1 and insert into the slot 31 and the through hole 33 on the outer surface of the L-shaped plate 32 to fix the position of the L-shaped plate 32 inside the slot 31. Install the L-shaped plate 32 and the positioning device 2 on the outer surface of the frame 1. Then, move the bracket on one side of the unwinding roller 4 to roll the paper material onto the unwinding roller 4. Move the bracket again to support the unwinding roller 4. Pass one end of the paper through the directional roller 5 and the traction roller 6 on the outer surface of the frame 1 and fix it to the surface of the take-up roller 8. Push the sliding rod 22 up and down at the two grooved rods 21 to adjust the sliding rod 22 and the... The height position of the pressure roller 24 is such that the outer surface of the pressure roller 24 contacts the paper surface located between the top rod 26 and the pressure roller 24. Then, the threaded ring 28 is rotated to move the threaded ring 28 on the outer surface of the screw 27, pressing one side against the outer surface of the groove rod 21 to fix the position of the sliding rod 22. The drive device on the outer surface of the frame 1 is controlled by the control box on one side of the frame 1 to drive the traction roller 6 to rotate, so that the paper on the outer surface of the unwinding roller 4 is released and moves between the directional roller 5, the pressure roller 24 and the top rod 26. The paper is cut by the cutting blade on the outer surface of the cutting roller 7. After the cutting is completed, it is wound on the outer surface of the winding roller 8. When the paper moves, the pressure roller 24 and the top rod 26 restrict the position of the paper to avoid the paper from deviating in position and causing wrinkles on the surface, which would affect the cutting effect.
