Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, specifically a paper slitting device. Background Technology

[0002] Paper slitting equipment is a type of automated or semi-automated processing machinery that is specifically designed to precisely cut, slit, or divide rolls or sheets of raw paper, finished paper, or various paper products into the required sizes according to preset widths, lengths, and specifications. Simply put, it is a specialized machine that cuts large-format raw paper into smaller-format sheets or rolls as needed by customers. It is a core piece of equipment in the later stages of paper processing.

[0003] The guide rollers of existing paper slitting equipment usually only rotate on a fixed axis and are difficult to move axially. When the paper shifts laterally due to uneven tension, uneven paper roll end face, roller parallelism error, etc., the equipment is difficult to actively correct the paper. The offset will gradually accumulate along the paper path, resulting in uneven edges and inconsistent widths of the narrow paper strip after slitting, and uneven winding edges, which affects the finished product qualification rate. Utility Model Content

[0004] The purpose of this invention is to provide a paper slitting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a paper slitting device, comprising a support, a paper feeding roller and a paper guiding roller, wherein the paper feeding roller is rotatably connected to the top center of the support, and a paper guiding roller is provided on one side of the middle of the support, and a guide roller is connected to the other side; a take-up roller is rotatably connected to the bottom of the support, and a slit cutting mechanism is installed on the side of the support near the guide roller, a paper cutting mechanism is connected on the side near the take-up roller, and a pressure roller mechanism is installed on the bottom of the support near the paper cutting mechanism; The cutting mechanism is used to cut folding guide lines on the paper, the pressure roller mechanism is used to press the paper, and the paper cutting mechanism is used to cut the paper. A servo motor is installed on the side of the bracket near the paper guide roller. A transmission base is fixedly connected to the output end of the servo motor. A rotating column is slidably connected to one side of the outer wall of the transmission base. The outer wall of the rotating column is fixedly connected to the paper guide roller. A spring is connected to the side of the rotating column near the transmission base, and a positioning ring is fixedly connected to the side away from the transmission base. A base is connected to one side of the outer wall of the positioning ring, and a base plate is connected to the other side. A transmission component is fixedly connected to the middle of the outer wall of the base and the base plate. A guide component is provided on the outer wall of the transmission component, and a fixing ring is connected to one side of the outer wall of the guide component. Both sides of the outer wall of the transmission component and the guide component are provided with guide slopes, which, together with the spring, cause the paper guide roller to move back and forth in a linear motion during rotation, in order to correct the lateral deviation of the paper.

[0006] Preferably, the rotating column and the bracket are rotatably connected, the middle part of the outer wall of the fixed ring is connected to the bracket, and the guide members are symmetrically distributed about the vertical midline of the fixed ring, and the transmission seat is in the shape of "I".

[0007] The servo motor drives the transmission base to rotate, causing the rotating column and the guide roller to rotate synchronously. During the rotation of the guide roller, the guide slope of the transmission component and the guide slope of the guide component continuously press against each other, driving the rotating column and the guide roller to make small horizontal reciprocating movements along the axial direction. At the same time, the spring provides elastic restoring force for the reciprocating movement.

[0008] Preferably, one side of the outer wall of the spring is fixedly connected to the transmission seat, and the paper guide roller, the transmission seat, the rotating column and the spring form an elastic telescopic mechanism, and the middle of the outer wall of the paper guide roller is provided with guide grooves distributed at equal angles.

[0009] The guide groove on the outer wall of the paper guide roller increases the friction with the paper, and in conjunction with the horizontal reciprocating movement, it corrects the lateral deviation of the paper in real time, ensuring smooth paper feeding.

[0010] Preferably, both the base and the substrate are arc-shaped, and the inner wall of the base and the substrate is provided with a limiting groove corresponding to the positioning ring. The outer wall of the base is fixedly connected to both sides, and the inner side of the substrate is provided with limiting holes corresponding to the insert plates, which, together with the positioning ring, are used to initially limit the base and the substrate.

[0011] Preferably, bolts are threaded on both sides of the outer wall of the substrate, and fixing holes corresponding to the bolts are opened inside the insert plate for locking the base and the substrate.

[0012] During installation, the base and the base plate are fastened to the outside of the positioning ring. At this time, the insert plate on the outer wall of the base is inserted into the inside of the base plate to complete the initial positioning. Then, the bolts are tightened through the insert plate to lock and fix it, thus completing the assembly of the transmission components.

[0013] As can be seen from the above, the paper slitting equipment provided by this utility model has the following beneficial effects.

[0014] The guide roller is driven to rotate by a servo motor. With the help of the inclined guide structure and spring of the transmission and guide components, the guide roller can move in a small horizontal reciprocating motion while rotating. This can correct the lateral deviation of the paper in real time, prevent the paper from running off-center during the slitting process, and improve the paper slitting accuracy.

[0015] The outer wall of the guide roller is equipped with a guide groove to increase the friction between the paper and the roller, further enhancing the correction effect. At the same time, it can stretch the paper surface and avoid wrinkles when cutting thin or soft paper.

[0016] The base and base plate adopt a detachable locking structure with insert plates and bolts, which facilitates the disassembly and maintenance of transmission components and guide components, and reduces the difficulty of equipment maintenance. Attached Figure Description

A servo motor 9 is installed on the side of the bracket 1 near the paper guide roller 3. The output end of the servo motor 9 is fixedly connected to a transmission seat 10. A rotating column 11 is slidably connected to one side of the outer wall of the transmission seat 10. The outer wall of the rotating column 11 is fixedly connected to the paper guide roller 3. A spring 12 is connected to the side of the rotating column 11 near the transmission seat 10. A positioning ring 13 is fixedly connected to the side away from the transmission seat 10. A base 14 is connected to one side of the outer wall of the positioning ring 13, and a base plate 15 is connected to the other side. A transmission component 18 is fixedly connected to the middle of the outer wall of the base 14 and the base plate 15. A guide component 19 is provided on the outer wall of the transmission component 18, and a fixing ring 20 is connected to one side of the outer wall of the guide component 19. Both sides of the outer wall of the transmission component 18 and the guide component 19 are provided with guide slopes, which, together with the spring 12, cause the paper guide roller 3 to move back and forth in a linear motion during rotation, in order to correct the lateral offset of the paper. The rotating column 11 is rotatably connected to the bracket 1. The middle of the outer wall of the fixed ring 20 is connected to the bracket 1. The guide members 19 are symmetrically distributed about the vertical midline of the fixed ring 20. The transmission seat 10 is in the shape of an "I". The outer wall of the spring 12 is fixedly connected to the transmission seat 10. The paper guide roller 3, the transmission seat 10, the rotating column 11 and the spring 12 form an elastic telescopic mechanism. The middle of the outer wall of the paper guide roller 3 is provided with guide grooves 21 distributed at equal angles. The base 14 and the substrate 15 are both arc-shaped. The middle of the inner wall of the base 14 and the substrate 15 is provided with a limiting groove corresponding to the positioning ring 13. The two sides of the outer wall of the base 14 are fixedly connected with insert plates 16. The two sides of the inner wall of the substrate 15 are provided with limiting holes corresponding to the insert plates 16. The positioning ring 13 is used to initially limit the base 14 and the substrate 15. The two sides of the outer wall of the substrate 15 are threaded with bolts 17. The inside of the insert plates 16 is provided with fixing holes corresponding to the bolts 17. The base 14 and the substrate 15 are used to lock the base 14 and the substrate 15.

[0021] For specific implementation, please refer to Figure 7 , Figure 8 and Figure 9 During installation, the base 14 and the base plate 15 are fastened to the outside of the positioning ring 13. At this time, the insert plate 16 on the outer wall of the base 14 is inserted into the inside of the base plate 15 to complete the initial positioning. Then, the bolts 17 are tightened through the insert plate 16 to lock and fix the components, thus completing the assembly of the transmission component 18.

[0022] See Figure 4 , Figure 5 and Figure 6When the equipment is working, the servo motor 9 drives the transmission seat 10 to rotate, which in turn drives the rotating column 11 and the guide roller 3 to rotate synchronously. During the rotation of the guide roller 3, the guide inclined surface of the transmission component 18 and the guide inclined surface of the guide component 19 continuously press against each other, driving the rotating column 11 and the guide roller 3 to make small horizontal reciprocating movements along the axial direction. At the same time, the spring 12 provides elastic restoring force for the reciprocating movement. The guide groove 21 on the outer wall of the guide roller 3 increases the friction with the paper and improves the heat dissipation effect. It also corrects the lateral deviation of the paper in real time in conjunction with the horizontal reciprocating movement, ensuring that the paper feed is flat. The shape of the guide groove 21 can be selected according to the requirements, such as herringbone groove, spiral groove, etc., which can flatten and remove wrinkles from the paper.

[0023] During the actual operation, the staff first checks whether the support 1, paper feeding roller 2, paper guide roller 3, and take-up roller 5 rotate smoothly without jamming; confirms that the servo motor 9, cutting mechanism 6, paper cutting mechanism 7, and pressure roller mechanism 8 are powered and have normal air supply; checks the inclined plane transmission assembly: the base 14 and base plate 15 are locked to the outside of the positioning ring 13 through the insert plate 16 and bolt 17, and the transmission component 18 and guide component 19 are in good contact with the inclined plane without looseness; the spring 12 has normal elasticity, ensuring that the rotating column 11 can extend and retract axially; confirms that the guide groove 21 on the outer wall of the paper guide roller 3 is clean and free of debris, ensuring stable friction with the paper.

[0024] The roll of raw paper is then installed at the feeding end of the equipment. The paper passes sequentially around the feed roller 2 → guide roller 3 → guide roller 4 → paper cutting mechanism 7 → pressure roller mechanism 8 → winding roller 5. The paper path is manually tightened to ensure that the paper is flat and wrinkle-free. The servo motor 9 is started and the speed is adjusted to drive the transmission seat 10 and the rotating column 11 to drive the guide roller 3 to rotate. Through the inclined plane cooperation, the guide roller 3 synchronously achieves small horizontal reciprocating movement. The reciprocating stroke is adjusted to adapt to the current paper width. The position and pressure of the slit mechanism 6, paper cutting mechanism 7, and pressure roller mechanism 8 are adjusted, and the slitting width and slit depth are set so that the pressure roller mechanism 8 presses the paper path to prevent the paper from becoming loose.

[0025] Servo motor 9 continuously drives the transmission base 10 to drive the rotating column 11 and the guide roller 3 to rotate at high speed; the transmission component 18 and the guide component 19 are pressed on the inclined surface, pushing the rotating column 11 to move axially, and the spring 12 provides the restoring force, so that the guide roller 3 moves back and forth in a small horizontal direction; the guide groove 21 on the outer wall of the guide roller 3 increases the friction, drives the paper to make synchronous horizontal micro-adjustment, and corrects the left and right deviation of the paper in real time; during the paper conveying process, the cutting mechanism 6 first presses and cuts the folding auxiliary line on the paper surface; then the pressure roller mechanism 8 continuously presses the paper to ensure stable tension; the paper cutting mechanism 7 accurately cuts the paper longitudinally.

[0026] After being slit, multiple finished paper strips are simultaneously wound up by the winding roller 5 to form finished paper rolls of uniform specifications. During the operation, real-time observation is conducted to check whether the paper is off-center, whether the cut is neat, and whether there are any wrinkles. If the deviation is abnormal, the speed of the servo motor 9 or the reciprocating stroke of the guide roller 3 is finely adjusted to optimize the correction effect.

[0027] This solution uses a servo motor 9 to drive the guide roller 3 to rotate. With the inclined guide structure of the transmission component 18 and the guide component 19 and the spring 12, the guide roller 3 can achieve a small horizontal reciprocating movement while rotating. This can correct the lateral deviation of the paper in real time, prevent the paper from running off-center during the slitting process, and improve the paper slitting accuracy.

[0028] The outer wall of the guide roller 3 is provided with a guide groove 21 to increase the friction between the paper and the roller body, further enhance the correction effect, and at the same time, it can stretch the paper surface to avoid wrinkles when cutting thin or soft paper.

[0029] The base 14 and base plate 15 adopt a detachable locking structure with insert plate 16 and bolt 17, which facilitates the disassembly and maintenance of transmission component 18 and guide component 19 and reduces the difficulty of equipment maintenance.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
