Description

Technical Field

[0001] This application relates to the field of paper slitting technology, and more specifically, to an integrated paper rolling and slitting device. Background Technology

[0002] In industrial fields such as paper processing and packaging material production, integrated paper roll cutting equipment is a key device for achieving efficient slitting of roll paper. Traditional slitting equipment has significant limitations in the design and function of the cutter roller structure, making it difficult to meet the comprehensive needs of modern industry for production efficiency, ease of operation and slitting accuracy.

[0003] Currently, the cutter rollers and blades of some slitting equipment adopt a fixed connection structure, such as welding or bolting. When a single blade wears out or needs to be replaced with a different size blade, the entire cutter roller module must be disassembled, and even the surrounding related parts need to be removed, which makes the maintenance process cumbersome. It also makes it difficult to adjust the spacing between the blades, which is not suitable for multi-size cutting needs. Furthermore, during the slitting process, the blades are prone to axial displacement due to vibration, loose bolts, or material impact, leading to the accumulation of slitting width errors. Traditional equipment relies on manual periodic inspections and cannot monitor the changes in blade position in real time. If the blade displacement is not detected in time, it will cause batch products to be out of size, or even cause equipment failures such as collision between the cutter roller and the support roller, resulting in serious economic losses. Therefore, it is necessary to develop an integrated paper rolling and cutting equipment that allows for quick assembly and disassembly of the cutting roller and blades, adjustable blade spacing, and real-time monitoring capabilities, in order to improve production efficiency, reduce maintenance costs, and ensure cutting accuracy. Utility Model Content

[0004] The purpose of this application is to provide an integrated paper rolling and cutting device that can effectively solve the problems of inconvenience in replacing the cutting roller and blade and the inability to detect errors in a timely manner in the prior art.

[0005] This application provides an integrated paper rolling and cutting device, including an unwinding mechanism, a guiding mechanism, a slitting frame and a winding mechanism. A support roller and a knife roller are provided between the two slitting frames. A lifting component is provided on the top of the slitting frame.

The surface of the slitting blade is provided with an adjustment element, and the slitting blade is fixed to the blade roller through the adjustment element. A distance sensor for monitoring the distance between the slitting blade and the adjacent slitting blade is provided on one side of the slitting blade.

[0006] As an optional solution to the technical solution in this application, the lifting component includes a fixed frame, an electric push rod, and a movable block. The fixed frame is fixed to the top of the cutting frame, and the electric push rod is installed on the top of the inner cavity of the fixed frame to drive the movable block to move vertically along the fixed frame.

[0007] As an optional solution to the technical solution of this application, the two ends of the cutter roller are set as semi-cylinders, which are adapted to the semi-connecting column, and the surface of the semi-connecting column and the surface of the corresponding end of the cutter roller are both provided with threads.

[0010] As an optional solution to the technical solution of this application, a positioning block is connected to the bottom of the screw, and the cutting blade is fixed by the fastening fit between the positioning block and the slide groove.

[0011] As an optional solution to the technical solution of this application, the slitting blade is an annular blade, which is sleeved on the outside of the cutter roller and can slide freely along the axial direction of the cutter roller.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: This application enables the quick connection or separation of the cutter roller and the semi-connecting column by rotating the connecting sleeve, thereby achieving quick assembly and disassembly of the cutter roller. At the same time, the slitting blade can be disassembled independently and axially slidably adjusted. Operators can replace worn blades or cutter roller modules individually, reducing manpower and time investment. Furthermore, the modular design allows for quick replacement of cutter rollers or blades of different specifications, adapting to the needs of multi-variety, small-batch production.

[0014] This application achieves adjustable axial spacing of the slitting blades through an adjusting component, and is equipped with a distance sensor to monitor the spacing between adjacent blades in real time to prevent loosening or displacement. The blade spacing can be precisely adjusted as needed to meet diverse slitting requirements. The distance sensor monitors the spacing in real time and triggers an alarm or shutdown when abnormalities occur, avoiding cutting errors caused by blade displacement, promptly detecting and correcting blade loosening problems, and reducing scrap rate and equipment failure risk.

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] Reference Figures 1-4This application discloses an integrated paper rolling and cutting device, including an unwinding mechanism 1, a guiding mechanism 2, a slitting frame 3, and a rewinding mechanism 4. The device is characterized in that: a support roller 5 and a cutting roller 7 are provided between the two slitting frames 3. The support roller 5 and the cutting roller 7 cooperate to form a cutting support point, ensuring uniform force on the paper during slitting and avoiding incomplete cutting or burr problems caused by insufficient local pressure, thus improving the cut quality. A lifting component 6 is provided at the top of the slitting frame 3, and a semi-connecting column 8 is provided on one side of the lifting component 6. A connecting sleeve 9 is fitted onto the surface of the semi-connecting column 8. Multiple... Each slitting blade 10 is independently detachable and has an adjustable spacing. The surface of the slitting blade 10 is provided with an adjustment component 11. The slitting blade 10 is fixed to the cutter roller 7 through the adjustment component 11. A distance sensor 12 is provided on one side of the slitting blade 10 to monitor the distance between adjacent slitting blades 10. The distance between adjacent slitting blades 10 is dynamically monitored through non-contact measurement such as laser or infrared to prevent displacement caused by loose positioning block 113. When the distance is abnormal, an alarm is triggered or the machine is automatically stopped to avoid cutting defects or equipment damage caused by blade misalignment and improve production safety.

[0019] Reference Figures 1-4 The lifting component 6 includes a fixed frame 61, an electric push rod 62, and a movable block 63. The fixed frame 61 is fixed to the top of the slitting frame 3. The electric push rod 62 is installed on the top of the inner cavity of the fixed frame 61 and is used to drive the movable block 63 to move vertically along the fixed frame 61. The electric drive enables the rapid lifting and lowering of the knife roller 7 without manual adjustment, shortening the paper preparation time such as paper feeding and machine adjustment. The two ends of the knife roller 7 are semi-cylindrical and are adapted to the semi-connecting column 8. The surface of the semi-connecting column 8 and the corresponding end surface of the knife roller 7 are both threaded. The two can be combined to form a complete thread. The semi-cylindrical design of the semi-connecting column 8 matches the shape of the end of the knife roller 7. The matching and merging process forms a complete thread, providing a structural basis for quick disassembly. The connecting sleeve 9 is threaded onto both of them, and the semi-connecting column 8 is fixed to the bottom of the movable block 63. The cutter roller 7 can be quickly disassembled and assembled by the engagement or disassembly of the connecting sleeve 9 and the semi-connecting column 8. The connecting sleeve 9 can be threaded onto the cutter roller 7 and the semi-connecting column 8 to achieve quick engagement or disassembly, which significantly shortens the cutter roller replacement time and improves maintenance efficiency. The surface of the cutter roller 7 is provided with a scale for observing the position between adjacent cutting blades 10 during adjustment. The scale can help operators to intuitively observe the blade position, improve adjustment efficiency and accuracy, and reduce trial and error costs.

[0020] Reference Figure 1 and Figure 4The surface of the cutter roller 7 is provided with a sliding groove 114 along the axial direction. The adjusting component 11 also includes a side plate 111 and a screw 112. The side plate 111 is fixed to one side of the slitting blade 10. The screw 112 passes through the side plate 111. The bottom of the screw 112 is connected to a positioning block 113. The slitting blade 10 is fixed by the fastening fit between the positioning block 113 and the sliding groove 114. The fastening fit between the positioning block 113 and the sliding groove 114 ensures the stability of the blade after it is fixed and prevents displacement during the cutting process. The slitting blade 10 is an annular blade that is sleeved on the outside of the cutter roller 7 and can slide freely along the axial direction of the cutter roller 7. The disassembly direction of the slitting blade 10 is consistent with the axial direction of the cutter roller 7. The slitting blade 10 is sleeved on the outside of the cutter roller 7 and can slide freely along the axial direction to achieve flexible adjustment of the spacing to adapt to different slitting width requirements. Furthermore, each blade can be replaced individually without disassembling the entire cutter roller, reducing maintenance costs.

[0021] In summary, the paper roll-cutting integrated equipment disclosed in this application, when in use, after starting the equipment, the unwinding mechanism 1 continuously releases the paper roll. The paper is guided by the roller group of the guiding mechanism 2 to ensure that the paper is aligned and enters the slitting area smoothly. The electric push rod 62 drives the movable block 63 to rise vertically along the fixed frame 61, which drives the knife roller 7 to separate from the support roller 5, forming an operating gap. The operator can use the gap to complete the paper threading or equipment inspection. Then the knife roller 7 descends to the working position and fits with the support roller 5 to form a cutting support point. If the knife roller 7 needs to be replaced, the connecting sleeve 9 is removed, and the knife roller 7 is separated from the semi-connecting column 8, realizing the quick disassembly of the knife roller 7. The spacing of the slitting blades 10 can be adjusted by the axial position of the slitting blades 10. By rotating the screw 112 in the adjusting component 11, the positioning block 113 is driven to abut against the inner wall of the slide groove 114 to achieve fixation. The distance sensor 12 monitors the spacing between adjacent blades in real time, and the data is fed back to the control system. In case of abnormality, an alarm or shutdown is triggered. Finally, the slitting paper strips are wound into independent paper rolls by the winding mechanism 4.
