Description

Technical Field

[0001] This utility model relates to the field of paper roll technology, specifically to an adjustable tension paper roll making device. Background Technology

[0002] In the papermaking process, a paper rolling machine is needed to roll up the paper for easy storage. When rolling the paper, a certain tension needs to be applied to the paper. Paper has a certain degree of flexibility. If the tension is insufficient, the paper is prone to loose stacking due to gravity or conveying fluctuations, forming wrinkles or "hollow rolls".

[0003] While current paper winding equipment can adjust the position of the tension roller before winding and apply appropriate tension to the paper during winding, there is an issue that is easily overlooked during the rewinding process.

[0004] During winding, the radius of the paper roll continuously increases. If the position of the tension roller is fixed, the horizontal distance between the tension roller and the paper roll decreases. Furthermore, since the tension roller is typically located above the paper roll, as the thickness of the paper roll increases, the vertical distance between the bottom of the paper roll and the highest point of the tension roller increases accordingly. When the horizontal distance decreases, the wrap angle of the paper on the tension roller decreases (the wrap angle refers to the angle at which the paper wraps around the tension roller). The change in vertical distance affects the pressure distribution of the paper on the tension roller. The combined effect of these two factors leads to changes in tension requirements, which is detrimental to improving the winding effect. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable tension paper rolling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable tension paper rolling device, comprising: a base and a sliding groove formed on the outer wall of the top of the base, and further comprising: an adjustment component installed on the outer wall of one side of the base, wherein an installation plate and an installation frame are respectively installed at both ends of the top of the adjustment component, and a pressure sensor is installed on the outer wall of one side of the installation plate, a contact component is movably inserted into the outer wall of one side of the installation plate, and an electric push rod is installed on the top of the installation plate, a tension roller is installed on the top of the electric push rod, and a winding roller is installed on the outer wall of the top of the base, and a winding motor is connected to one end of the winding roller, a rotating shaft is rotatably installed on the inner wall of the installation frame, and a drive motor is connected to one end of the rotating shaft, a plurality of equidistantly distributed flattening components are installed on the outer wall of the rotating shaft, a controller is installed on the outer wall of one side of the base, and a guide frame is installed at one end of the outer wall of the top of the base.

[0007] The adjustment assembly includes an adjustment motor, a bidirectional threaded rod connected to one end of the output shaft of the adjustment motor, and sliders screwed to both ends of the bidirectional threaded rod.

[0008] The mounting plate and mounting bracket are respectively mounted on the top of the two sliders.

[0009] The contact assembly includes two movable rods, a spring sleeved on the outside of the two movable rods, and a contact roller mounted on one end of the two movable rods.

[0010] The leveling component includes a pressure roller and multiple equidistantly distributed rubber pads installed on the outer wall of the pressure roller.

[0011] The pressure sensor, electric push rod, winding motor, drive motor, and regulating motor are all connected to the controller via signal lines.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses an adjustable tension paper rolling device. As the paper roll gradually thickens during winding, the contact component is squeezed and moves to touch the pressure sensor. The pressure sensor transmits a signal to the controller. The controller expands the gap between the mounting plate and the mounting frame by adjusting the component to accommodate the thickening paper roll. This keeps the horizontal distance between the tension roller and the paper roll within a stable range. At the same time, the tension roller can be lowered by retracting the electric push rod piston rod, keeping the vertical distance between the highest point of the tension roller and the bottom of the paper roll within a stable range, thereby improving the winding effect of the paper roll.

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides an adjustable tension paper rolling device, comprising: a base 1 and a groove 2 formed on the top outer wall of the base 1, and an adjustment component 3 installed on one side outer wall of the base 1. The top two ends of the adjustment component 3 are respectively equipped with an installation plate 4 and an installation frame 5. A pressure sensor 6 is installed on one side outer wall of the installation plate 4. A contact component 7 is movably inserted into one side outer wall of the installation plate 4. An electric push rod 8 is installed on the top of the installation plate 4. A tension roller 9 is installed on the top of the electric push rod 8. A take-up roller 10 is installed on the top outer wall of the base 1. One end of the take-up roller 10 is connected to a take-up motor 11. A rotating shaft 12 is rotatably installed on the inner wall of the installation frame 5. One end of the rotating shaft 12 is connected to a drive motor 14. Multiple evenly distributed flattening components 13 are installed on the outer wall of the rotating shaft 12. A controller 15 is installed on one side outer wall of the base 1. A guide frame 16 is installed on one end of the top outer wall of the base 1.

[0022] It should be noted here that: the paper 17 can be passed through the guide frame 16 and above the tension roller 9, and one end of the paper 17 can be fixed on the take-up roller 10. Tension can be applied to the paper 17 through the tension roller 9. The take-up motor 11 drives the take-up roller 10 to rotate, thus winding the paper 17. During the winding process, the drive motor 14 drives the rotating shaft 12 to rotate relative to the take-up roller 10, which in turn drives the leveling component 13 to rotate. During the rotation of the leveling component 13, its outer wall can contact the paper roll. When in contact, it can press on the surface of the paper roll, squeezing the interlayer air and making the overall density of the paper roll more uniform. The component 7 is attached to one side of the paper roll. As the paper roll gradually thickens during winding, the contact component 7 is squeezed and moves to touch the pressure sensor 6. The pressure sensor 6 transmits a signal to the controller 15. The controller 15 increases the distance between the mounting plate 4 and the mounting bracket 5 by adjusting the component 3 to accommodate the thickening paper roll. This keeps the horizontal distance between the tension roller 9 and the paper roll within a stable range. At the same time, the piston rod of the electric push rod 8 can be contracted to drive the tension roller 9 to descend a certain height, keeping the vertical distance between the highest point of the tension roller 9 and the bottom of the paper roll within a stable range, thereby improving the winding effect of the paper roll.

[0023] In a preferred embodiment, the adjustment assembly 3 includes an adjustment motor 301, a bidirectional threaded rod 302 connected to one end of the output shaft of the adjustment motor 301, and sliders 303 screwed to both ends of the bidirectional threaded rod 302; the mounting plate 4 and the mounting bracket 5 are respectively mounted on the top of the two sliders 303.

[0024] It should be noted that the adjusting motor 301 can drive the bidirectional threaded rod 302 to rotate, which in turn drives the two sliders 303 to move away from each other, thereby increasing the distance between the mounting plate 4 and the mounting bracket 5.

[0025] In a preferred embodiment, the contact assembly 7 includes two movable rods 701, a spring 702 sleeved on the outside of the two movable rods 701, and a contact roller 703 mounted on one end of the two movable rods 701.

[0026] It should be noted here that as the paper roll gradually thickens during winding, it pushes the contact roller 703, causing the contact roller 703 to move closer to the pressure sensor 6. When it touches the pressure sensor 6, it will also compress the spring 702.

[0027] In a preferred embodiment, the leveling component 13 includes a pressure roller 1301 and a plurality of equidistantly distributed rubber pads 1302 mounted on the outer wall of the pressure roller 1301.

[0028] It should be noted here that: the drive motor 14 drives the rotating shaft 12 to rotate relative to the winding roller 10, which in turn drives the pressure roller 1301 to rotate. The rubber pad 1302 can come into contact with the paper roll as the pressure roller 1301 rotates. When in contact, it can press on the surface of the paper roll, squeeze the air between layers, and make the overall density of the paper roll more uniform.

[0029] In a preferred embodiment, the pressure sensor 6, the electric push rod 8, the winding motor 11, the drive motor 14, and the regulating motor 301 are all connected to the controller 15 via signal lines.

[0030] It should be noted that the controller 15 can control the pressure sensor 6, the electric push rod 8, the winding motor 11, the drive motor 14, and the regulating motor 301.

[0031] Working principle: Paper 17 can be passed through the guide frame 16 and above the tension roller 9, and one end of paper 17 is fixed on the take-up roller 10. Tension can be applied to paper 17 through tension roller 9. The take-up motor 11 drives the take-up roller 10 to rotate and take up paper 17. During the winding process, the drive motor 14 drives the rotating shaft 12 to rotate relative to the take-up roller 10, which in turn drives the pressure roller 1301 to rotate. The rubber pad 1302 can come into contact with the paper roll as the pressure roller 1301 rotates. When in contact, it can press on the surface of the paper roll and squeeze the air between layers, making the overall density of the paper roll more uniform.

[0032] As the paper roll gradually thickens during winding, it pushes against the contact roller 703, causing it to move closer to the pressure sensor 6. Upon contact with the pressure sensor 6, the contact roller 703 compresses the spring 702. The pressure sensor 6 transmits a signal to the controller 15. The controller 15 then controls the adjusting motor 301 to rotate the bidirectional threaded rod 302, which in turn moves the two sliders 303 away from each other. This widens the gap between the mounting plate 4 and the mounting bracket 5, making it easier to accommodate the thickening paper roll. This keeps the horizontal distance between the tension roller 9 and the paper roll within a stable range. Simultaneously, the piston rod of the electric push rod 8 can retract, causing the tension roller 9 to descend a certain height, keeping the vertical distance between the highest point of the tension roller 9 and the bottom of the paper roll within a stable range, thereby improving the winding effect of the paper roll.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
