Description

Technical Field

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

[0002] In the paper processing industry, paper slitting and feeding equipment is a key piece of equipment for achieving continuous paper slitting and winding, and is widely used in packaging, printing, and paper processing industries. Its core function is to slit the raw paper roll to a preset width and then wind it into finished paper rolls of uniform specifications using winding rollers. The efficiency, stability, and winding quality of the winding process directly affect the overall production efficiency. In related technologies, in order to improve the efficiency of paper alignment, for example, the patent with prior art announcement number CN221792942U provides a paper cutting device. This paper cutting device sends the paper to a lifting platform, where the first and second alignment components align the paper from two directions, making the paper neatly stacked. Then, the paper is sent from the lifting platform to the paper cutting mechanism for cutting. After completion, the paper is sent out through the unloading mechanism, realizing automatic paper alignment. Moreover, the paper is transported by the lifting platform, reducing labor intensity and improving efficiency.

[0003] While the existing technical solutions mentioned above have solved the problems of high labor intensity and low efficiency of manually aligning paper, traditional winding devices mostly adopt a single-roller winding design. When the winding roller reaches the preset roll diameter, the machine needs to be stopped to unload the material, which leads to production interruption. Each time the machine stops to change rolls, the full roll needs to be disassembled manually, an empty roll needs to be installed, and the paper needs to be re-threaded, which takes a long time for each operation.

[0004] In view of this, we propose a paper slitting and feeding device. Utility Model Content

[0005] The purpose of this application is to provide a paper slitting and feeding device that can effectively solve the problems of insufficient continuous operation and low roll changing efficiency in the prior art.

[0006] This application provides a paper slitting and feeding device, comprising: A paper slitting machine, wherein side plates and side discs are fixedly connected to both sides of the paper slitting machine's winding section, and the side plates are provided with a cutting roller drive mechanism and a turntable stabilizer, and three winding rollers are provided between the side plates and the side discs; The first annular groove is formed on the inner side wall of the side plate. The side of the cutting roller drive mechanism has a notch. The winding roller is mainly composed of two half rollers, and an edge detection mechanism is provided between the two half rollers.

[0007] As an optional solution to the technical solution of this application, the cutting roller drive mechanism includes a rotating disk placed on one side of the side plate, a cutting roller motor installed on the outer side wall of the side plate, a transmission rod fixedly connected at the center of one side wall of the rotating disk, and the output shaft of the cutting roller motor rotatably passes through the surface of the side plate and is connected to the transmission rod for transmission.

[0008] As an optional solution to the technical solution of this application, the three take-up rollers are arranged in a circular array with the center of the rotating disk as the center. A take-up motor is provided on one side of each take-up roller. The take-up motor is mounted on the rotating disk. The output shaft of the take-up motor passes through the surface of the rotating disk and is connected to the take-up roller. Top holes are provided on the top of the two half rollers.

[0009] As an optional solution to the technical solution of this application, the turntable stabilizer includes an annular groove II formed on the inner side wall of the side plate, a connecting ring rotatably connected to the inner cavity of the annular groove II, and a connecting rod fixedly connected between the connecting ring and the turntable.

[0010] As an optional solution to the technical solution of this application, the edge detection mechanism includes an internal cavity opened between two half rollers. One side of the internal cavity is connected to the outside. A bidirectional threaded rod is rotatably connected to the inner wall of the internal cavity placed on one half roller. One end of the bidirectional threaded rod extends to the outside of the half roller and is fixedly connected to a knob. Both ends of the bidirectional threaded rod are threadedly connected to a movable seat. An edge detection sensor is embedded in the top of the movable seat.

[0011] As an optional solution to the technical solution in this application, the two ends of the bidirectional threaded rod are provided with two opposite threads, and the position of the edge detection sensor corresponds to the top hole.

[0012] As an optional solution to the technical solution of this application, one end of the knob is placed in the inner cavity of the annular groove and is slidably connected to its inner wall, and the movable seat is slidably connected to the inner wall of the built-in cavity.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: This application achieves parallel operation of winding and unloading by cooperating with three ring array-distributed winding rollers and a rotating disk: when a winding roller is fully wound, the cutting roller motor drives the rotating disk to rotate it to the notch, and the operator can directly complete the full roll disassembly and empty roll installation at the unloading position without stopping the machine to interrupt the slitting process, shortening the downtime for changing rolls in the traditional single-roll winding mode and significantly improving the continuous operation capability.

[0014] The turntable stabilizer in this application uses the rotational engagement of the annular groove and the connecting ring, combined with the reinforcement of the turntable by the connecting rod, to reduce paper shifting and equipment failure caused by structural shaking, thereby reducing the frequency of maintenance downtime. The edge detection mechanism adjusts the position of the edge detection sensor through the bidirectional threaded rod, which can adapt to different paper widths. It works with the top hole to monitor edge shifting in real time and correct it in time, thereby reducing the scrap rate caused by edge slippage. Attached Figure Description

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

[0018] Reference Figures 1-5 This application discloses a paper slitting and feeding device, including a paper slitting machine 1, the core body of the device, which realizes the slitting and processing of raw paper and provides an installation benchmark and working platform for mechanisms such as winding, changing, and edge detection. Side plates 2 and side disks 3 are fixedly connected to both sides of the winding end of the paper slitting machine 1. The side disks 3 and side plates 2 symmetrically support the winding rollers 5. A ring groove 9 is opened for the sliding of the knob 85, which restricts the winding rollers 5 and plays a limiting and guiding role. The side plates 2 are provided with a cutting roller drive mechanism 4 and a turntable stabilizer 6. The turntable stabilizer 6 is used to reinforce the rotating disk 41. The cutting roller drive mechanism 4 as a whole provides power and transmission for the winding rollers 5 to rotate, realizing the switching of the work position of the full roll and the empty roll. Three winding rollers 5 are arranged between the side plates 2 and the side disks 3 to wind the slitting paper. The annular groove 9 is used to accommodate the knob 85 and allow it to slide. The annular groove 9 is opened on the inner side wall of the side plate 3. The side of the cutting roller drive mechanism 4 has a notch 7, which serves as a dedicated unloading station for the full roll take-up roller. The take-up roller 5 is mainly composed of two half rollers 51. The two half rollers 51 are detachably threaded and combined together. An edge detection mechanism 8 is set between the two half rollers 51 to detect the paper edge deviation, adjust the detection position to adapt to different widths of paper, and provide feedback on the deviation signal. The three take-up rollers 5 are arranged in a circular array with the center of the rotating disk 41 as the center. A take-up motor 52 is set on one side of the take-up roller 5 to independently drive the take-up roller 5 to rotate and adjust the take-up speed and tension. The take-up motor 52 is mounted on the rotating disk 41. The output shaft of the take-up motor 52 passes through the surface of the rotating disk 41 and is connected to the take-up roller 5. The top of the two half rollers 51 is provided with a top hole 53.

[0019] Reference Figure 1 , Figure 2 and Figure 3 The cutting roller drive mechanism 4 includes a rotating disk 41 placed on one side of the side plate 2, which rotates around the transmission rod 43 to realize the circular rotation of the three take-up rollers 5. A cutting roller motor 42 is installed on the outer wall of the side plate 2 to provide rotational power to the rotating disk 41. A transmission rod 43 is fixedly connected to the center of one side wall of the rotating disk 41 to transmit rotational power. The output shaft of the cutting roller motor 42 rotates through the surface of the side plate 2 and is connected to the transmission rod 43.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The turntable stabilizer 6 includes an annular groove 61 formed on the inner side wall of the side plate 2. A connecting ring 62 is rotatably connected to the inner cavity of the annular groove 61. A connecting rod 63 is fixedly connected between the connecting ring 62 and the turntable 41.

[0021] Reference Figure 4 and Figure 5 The edge detection mechanism 8 includes an internal cavity 81 located between two half-rollers 51. One side of the internal cavity 81 is connected to the outside. A bidirectional threaded rod 82 is rotatably connected to the inner wall of the internal cavity 81 located on one half-roller 51. One end of the bidirectional threaded rod 82 extends to the outside of the half-roller 51 and is fixedly connected to a knob 85. Both ends of the bidirectional threaded rod 82 are threadedly connected to a movable seat 83. An edge detection sensor 84 is embedded in the top of the movable seat 83 to detect the paper edge offset in real time through the top hole 53. Two opposite threads are distributed at the two ends of the bidirectional threaded rod 82. The position of the edge detection sensor 84 corresponds to the top hole 53. One end of the knob 85 is located in the inner cavity of the annular groove 9 and is slidably connected to its inner wall. The movable seat 83 is slidably connected to the inner wall of the internal cavity 81.

[0022] In summary, when the paper slitting and feeding equipment disclosed in this application is in use, the paper slitting machine 1, as the core body, slits the raw paper. The slit paper is guided onto the winding roller 5 between the side plate 2 and the side disc 3. The winding motor 52, mounted on the rotating disc 41, independently drives the winding roller 5 to rotate. By adjusting the speed and tension, the paper is wound smoothly. During the winding process, the edge detection mechanism 8 starts to work. The operator can drive the bidirectional threaded rod 82 to rotate by rotating the knob 85. Since the bidirectional threaded rod 82 has opposite threads at both ends, it will drive the two moving seats 83 to move closer or further away from each other along the built-in cavity 81, thereby adjusting the position of the edge detection sensor 84 to adapt to the current paper width. The edge detection sensor 84 detects the paper edge offset in real time through the top hole 53 and feeds back the signal. Knob 85 slides within annular groove 9. Side plate 3 and side plate 2 cooperate to limit and guide the winding roller 5. Connecting ring 62 in turntable stabilizer 6 rotates along annular groove 61, and connects with connecting rod 63 to reinforce turntable 41 to prevent it from shaking during rotation. When a winding roller 5 is wound to the preset diameter to form a full roll, the cutting roller motor 42 in the cutting roller drive mechanism 4 starts and drives the turntable 41 to rotate around its center through transmission rod 43. Since the three winding rollers 5 are arranged in a circular array around the center of the turntable 41, the turntable 41 will rotate the full roll winding roller 5 to the notch 7 on one side of the cutting roller drive mechanism 4. The operator can disassemble the full roll and install the empty roll at this dedicated unloading station. During this process, the equipment does not need to be stopped, realizing parallel operation of winding and unloading, and ensuring continuous production.
