Description

Technical Field

[0001] This utility model relates to the field of tissue paper production equipment technology, specifically to an auxiliary device for improving the accuracy and efficiency of tissue paper rolling. Background Technology

[0002] In the tissue paper production process, the winding process is a crucial step in rolling the slit paper webs into standard paper rolls. Traditional winding equipment typically uses a single-roller drive structure. An existing patent for a tissue paper packaging machine, patent publication number CN210235534U, includes a frame, a paper conveyor belt assembly, a paper roll, a tissue paper channel, a cutter, and a winding assembly. The paper conveyor belt assembly has a connecting plate on its upper right side, fixed below the worktable. The connecting plate is equipped with an active speed-changing disc and a driven speed-changing wheel. The driven speed-changing wheel drives the paper conveyor belt assembly via a chain. The original tissue paper roll is placed on the paper roll, and the paper conveyor belt assembly drives the original tissue paper roll into the tissue paper channel, where the cutter and winding assembly roll the tissue paper into small rolls that meet the requirements. Due to the adoption of the above technical solution, this utility model has the following beneficial effects: The utility model has a simple structure, requires very few manual assistance steps during the rolling process, and is highly efficient. While reducing the probability of paper breakage, it also significantly improves the winding speed and production efficiency of tissue paper factories.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the traditional single-roller drive structure lacks a real-time tension feedback mechanism, and the paper web is prone to tension instability during the winding process due to factors such as changes in roller speed and uneven paper web thickness. Excessive tension may break the paper web or cause deformation of the core, while insufficient tension will lead to loose and wrinkled paper rolls. Therefore, we have proposed a paper towel winding auxiliary machine to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a paper towel rolling auxiliary machine, which solves the problem that traditional single-roller drive structures lack a real-time tension feedback mechanism. During the rolling process, the paper web is prone to tension instability due to factors such as changes in roller speed and uneven paper web thickness. Excessive tension may break the paper web or cause deformation of the core, while insufficient tension will lead to loose and wrinkled paper rolls.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a paper towel rolling auxiliary machine, including a support mechanism, wherein a notch is provided inside the support mechanism, and a guide rail mechanism is fixedly connected inside the notch, and the guide rail mechanism is provided in two places;

[0006] The two guide rail mechanisms are fixedly connected to the front and rear sides of the support mechanism slot. Both guide rail mechanisms have longitudinal slots inside, and lifting push rods are fixedly connected inside the longitudinal slots. Displacement components are fixedly connected to the top surfaces of the two lifting push rods. The displacement components are slidably connected inside the guide rail mechanism. Pressure rollers are rotatably connected to the inner sides of the two displacement components. A piezoresistor is applied to the outer circumferential surface of the pressure roller.

[0007] Preferably, a leg assembly is fixedly connected to the bottom surface of the support mechanism. There are two leg assemblies, which are fixedly connected in a straight line array on the left and right sides of the bottom surface of the support mechanism.

[0008] Preferably, the inner side of the support mechanism is equipped with guide rollers. There are two guide rollers in total, and the two guide rollers are arranged in a longitudinal array and rotated and connected to the upper and lower sides inside the support mechanism.

[0009] Preferably, a servo motor A is mounted on the front end face of the support mechanism, and an output shaft is provided on the rear side of the servo motor A, which is connected to the guide roller.

[0010] Preferably, the inner sides of the two guide rollers pass through a tissue component, the tissue component passes over the upper side of the pressure roller, and a guide frame mechanism is fixedly connected to the outer side of the support mechanism.

[0011] Preferably, there are two guide frame mechanisms, and the two guide frame mechanisms are fixedly connected to the front and rear sides of the support mechanism in opposite directions. The inner side of each guide frame mechanism is fixedly connected with a longitudinally arranged longitudinal push rod.

[0012] Preferably, a connecting plate is fixedly connected to the output end of the longitudinal push rod, two sliders are fixedly connected to the outer side of the connecting plate in opposite directions, a connecting sleeve is rotatably connected to the inner side of the connecting plate, a fixing bolt for limiting the winding roller is screwed to the outer side of the connecting sleeve, and a servo motor B for driving the connecting sleeve to rotate is fixedly connected to the front end of the connecting plate. Beneficial effects

[0013] This utility model provides a paper towel rolling auxiliary machine. Compared with the prior art, it has the following advantages:

[0014] This tissue paper roll-up auxiliary machine uses the pressure roller's pressure-sensitive resistor to capture the tension changes of the tissue paper in real time. It dynamically adjusts the speed of the guide roller through servo motor A, and adaptively adjusts the height of the pressure roller with the lifting push rod, forming a "detection-feedback-adjustment" closed-loop system. Compared with the tension fluctuations of traditional single-roller drive, this device significantly improves the tension control accuracy and solves the quality problems caused by unstable tension.

[0015] This tissue paper roll-up auxiliary machine, through the combination of a guide frame mechanism and a longitudinal push rod, enables the take-up roller to be raised and lowered quickly and precisely aligned. Combined with the quick-release and disassembly structure of the fixing bolts, it significantly shortens the roll changeover time. The clamping and conveying structure of the dual guide rollers disperses the stress on the tissue paper components, supporting higher roll-up speeds and rapid switching between multiple specifications of tissue paper components. No manual adjustment of the mechanical structure is required, which improves the adaptability of the equipment to different production needs, reduces manual intervention costs, and enhances production continuity. In addition, the stable support of the support leg assembly and the precise guidance of the guide rail mechanism ensure smooth operation of the equipment and extend the service life of the core components.

[0023] 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.

[0024] Please see Figures 1-6This utility model provides a technical solution: a paper towel rolling auxiliary machine, including a support mechanism 1, the support mechanism 1 has a notch inside, and a guide rail mechanism 3 is fixedly connected inside the notch, and the guide rail mechanism 3 is provided in two places.

[0025] Two guide rail mechanisms 3 are fixedly connected to the front and rear sides of the support mechanism 1 inside the notch. Both guide rail mechanisms 3 have longitudinal grooves inside. Lifting push rods 301 are fixedly connected inside the longitudinal grooves. Displacement components 3011 are fixedly connected to the top surfaces of the two lifting push rods 301. The displacement components 3011 are slidably connected inside the guide rail mechanism 3. Pressure rollers 3012 are rotatably connected to the inner side of the two displacement components 3011. A pressure roller 3012 is applied to the outer circumferential surface of the pressure roller 3012.

[0026] Two guide rail mechanisms 3 are fixed by the notch inside the support mechanism 1. The longitudinal groove of the guide rail mechanism 3 drives the displacement component 3011 to slide up and down through the lifting push rod 301, so that the pressure roller 3012 can adjust its height with the displacement component 3011, thereby realizing the adjustment of the pressing force on the tissue paper 1013 of different thicknesses. At the same time, the pressure-sensitive resistor on the outer periphery of the pressure roller 3012 monitors the pressure data in real time, providing feedback for tension control.

[0027] See Figures 1-3 The support mechanism 1 has two support leg assemblies 101 fixedly connected to the bottom end surface. The two support leg assemblies 101 are fixedly connected to the left and right sides of the bottom end surface of the support mechanism 1 in a straight line array.

[0028] The two support leg assemblies 101 at the bottom of the support mechanism 1 are arranged in a straight array and are fixedly connected to form a stable bottom support structure, ensuring that the equipment remains horizontal during the winding process and avoiding tension fluctuations or winding deviations of the tissue paper 1013 due to unstable support.

[0029] See Figures 2-5 The inner side of the support mechanism 1 is equipped with a guide roller 1011. There are two guide rollers 1011 in total. The two guide rollers 1011 are arranged in a longitudinal array and rotated and connected to the upper and lower sides inside the support mechanism 1.

[0030] The two guide rollers 1011 on the inner side of the support mechanism 1 are longitudinally distributed and driven to rotate by the servo motor A1012 to form a clamping and conveying path for the tissue paper 1013, ensuring that the tissue paper 1013 enters the winding area smoothly. At the same time, the tension is dispersed by the double roller drive, reducing the stress concentration problem of single roller drive.

[0031] See Figures 1-5 A servo motor A1012 is mounted on the front end face of the support mechanism 1. An output shaft is provided on the rear side of the servo motor A1012, and the output shaft is connected to the guide roller 1011.

[0032] The servo motor A1012 is connected to the guide roller 1011 via the output shaft, which can precisely control the rotation speed of the guide roller 1011. With the feedback of the pressure roller 3012's pressure-sensitive resistor, the conveying speed and tension of the tissue paper 1013 can be adjusted in a coordinated manner, avoiding tissue paper breakage or loosening caused by speed fluctuations.

[0033] See Figures 3-6 The inner side of the two guide rollers 1011 passes through the tissue paper component 1013, the tissue paper component 1013 passes through the upper side of the pressure roller 3012, and the outer side of the support mechanism 1 is fixedly connected to the guide frame mechanism 2.

[0034] After being conveyed by the guide roller 1011, the tissue paper 1013 passes over the upper side of the pressure roller 3012. The guide frame mechanism 2 is fixed on both sides of the support mechanism 1. The longitudinal push rod 201 on its inner side drives the slider 2012 to slide along the guide frame mechanism 2 through the connecting plate 2011, ensuring that the take-up roller 2016 is aligned with the guide roller 1011 and preventing edge displacement of the tissue paper 1013 during winding.

[0035] See Figures 1-2 There are two guide frame mechanisms 2, and the two guide frame mechanisms 2 are fixedly connected to the front and rear sides of the support mechanism 1 in opposite directions. The inner sides of the two guide frame mechanisms 2 are fixedly connected with longitudinally arranged longitudinal push rods 201.

[0036] Two guide frame mechanisms 2 are symmetrically arranged on the front and rear sides of the support mechanism 1. The longitudinal push rod 201 drives the connecting plate 2011 to move up and down, so that the connecting sleeve 2013 drives the winding roller 2016 to rise and fall synchronously, which can adapt to the installation requirements of winding rollers 2016 with different diameters. At the same time, the sliding cooperation between the slider 2012 and the guide frame mechanism 2 ensures the stability of the lifting process.

[0037] See Figures 4-5 A connecting plate 2011 is fixedly connected to the output end of the longitudinal push rod 201. Two sliders 2012 are fixedly connected to the outer side of the connecting plate 2011 in opposite directions. A connecting sleeve 2013 is rotatably connected to the inner side of the connecting plate 2011. A fixing bolt 2014 for limiting the winding roller 2016 is screwed onto the outer side of the connecting sleeve 2013. A servo motor B2015 for driving the connecting sleeve 2013 to rotate is fixedly connected to the front end of the connecting plate 2011.

[0038] The output end of the longitudinal push rod 201 is connected to the connecting sleeve 2013 via the connecting plate 2011. The servo motor B2015 drives the connecting sleeve 2013 to rotate, which in turn drives the take-up roller 2016 to rotate and take up the tissue paper unit 1013. The fixing bolt 2014 is screwed onto the outside of the connecting sleeve 2013, which allows for quick assembly and disassembly of the take-up roller 2016, enabling rapid replacement of cores of different specifications and improving roll changing efficiency.

[0039] During operation, firstly, the support mechanism 1 is fixed to the ground via the support leg assembly 101 at the bottom to ensure horizontal stability. The guide rail mechanism 3 is fixed in the notch of the support mechanism 1. The longitudinal slots of the two guide rail mechanisms 3 respectively accommodate the lifting push rod 301 and the displacement assembly 3011. The pressure roller 3012 is suspended inside the guide rail mechanism 3 via the displacement assembly 3011. The pressure resistor on its outer periphery is in a state of being to be detected. The guide roller 1011 is connected via the output shaft of the servo motor A1012 and is in a stationary state. The guide frame mechanism 2 is symmetrically installed on both sides of the support mechanism 1. The longitudinal push rod 201 is connected to the slider 2012 via the connecting plate 2011. The winding roller 2016 is fixed to the outside of the connecting sleeve 2013 via the fixing bolt 2014. The servo motor B2015 is in a standby state.

[0040] Then, the servo motor A1012 is started, and its output shaft drives the guide roller 1011 to rotate. The slit tissue paper 1013 is clamped and conveyed by the guide roller 1011, passing longitudinally through the upper side of the pressure roller 3012. The pressure-sensitive resistor on the outer periphery of the pressure roller 3012 detects the tension of the tissue paper 1013 in real time. When the tension of the tissue paper 1013 increases, the resistance of the pressure-sensitive resistor changes and is fed back to the control system. The control system adjusts the speed of the servo motor A1012 and reduces the conveying speed of the guide roller 1011 to relieve the tension. If the tension is too small, the servo motor A1012 accelerates its rotation and increases the conveying speed to tighten the tissue paper 1013. For tissue paper 1013 of different thicknesses, the lifting push rod 301 is started and moves up and down along the longitudinal groove of the guide rail mechanism 3.

[0041] When the lifting push rod 301 extends, it pushes the displacement component 3011 upward, and the pressure roller 3012 rises accordingly, increasing the distance between it and the guide roller 1011 to accommodate the passage of thick paper towels. When the lifting push rod 301 shortens, the displacement component 3011 drives the pressure roller 3012 downward, reducing the distance to ensure the pressing force of thin paper towels. During this process, the displacement component 3011 achieves smooth sliding through the cooperation of the slider 2012 and the guide rail mechanism 3, avoiding the pressure roller 3012 from shaking and affecting the tension detection accuracy.

[0042] The longitudinal push rod 201 drives the slider 2012 to slide along the guide frame mechanism 2 through the connecting plate 2011, adjusting the longitudinal position of the take-up roller 2016 so that it is aligned with the guide roller 1011 and the pressure roller 3012. The servo motor B2015 is started, which drives the connecting sleeve 2013 to rotate, thereby rotating the take-up roller 2016 to take up the tissue paper 1013. The take-up roller 2016 is fixed to the connecting sleeve 2013 by the fixing bolt 2014 to ensure stability during rotation.

[0043] During the winding process, the pressure-sensitive resistor continuously monitors the tension, and the control system synchronously adjusts the speeds of servo motors A1012 and B2015 to achieve speed matching between "conveyor-winder" operations, preventing the tissue paper component 1013 from breaking or becoming loose.

[0044] When the take-up roller 2016 finishes winding, servo motors A1012 and B2015 stop, and the longitudinal push rod 201 drives the connecting plate 2011 to descend, causing the take-up roller 2016 to disengage from the winding position. The fixing bolt 2014 is loosened, the fully wound take-up roller 2016 is disassembled, and after installing a new core, it is locked by the fixing bolt 2014. If a take-up roller 2016 of a different diameter is replaced, its height is readjusted by the longitudinal push rod 201, and the above winding process is repeated.

[0045] In summary, this device, by providing a connecting sleeve 2013, enables the rapid installation of the take-up roller 2016.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
