Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and more specifically, to a decorative paper winding device. Background Technology

[0002] With the rapid development of the decoration industry, decorative paper, as an important decorative material, is widely used in furniture, architectural interiors, and other fields. Its excellent visual effects and decorative properties make it a key choice for both consumers and manufacturers. In the production process of decorative paper, winding is a crucial step, as the quality of winding directly affects the appearance, performance, and market competitiveness of the final product. During winding, the decorative paper must be wound evenly and tightly onto the winding drum to ensure that the paper is neither loose nor wrinkled, thus maintaining the consistency and high quality of the roll.

[0003] However, many problems still exist in existing decorative paper winding equipment, especially the tendency for the decorative paper to loosen during the winding process. This loosening not only affects the tightness of the roll but also causes wrinkles, creases, or gaps on the paper surface, and in severe cases, it can even lead to tearing of the paper. Utility Model Content

[0004] The purpose of this invention is to provide a decorative paper winding device that can effectively prevent the decorative paper from loosening during the winding process and ensure that the paper remains in a uniform and compact state throughout the entire winding process.

[0005] This utility model is achieved through the following technical solution:

[0006] A decorative paper winding device, comprising:

[0007] A support frame, on which multiple guide rollers are rotatably mounted for guiding decorative paper;

[0008] A take-up roller, which is rotatably mounted on the bracket, and a drive component for driving the take-up roller to rotate is fixedly mounted on the bracket;

[0009] The tension roller is rotatably mounted on a fixed seat that is slidably mounted on the bracket, and the bracket is provided with an adjusting member for driving the fixed seat to move back and forth in a direction away from or close to the take-up roller;

[0010] The nozzle is located between the take-up roller and the tension roller. The nozzle is connected to the air pump through a connecting pipe. A nozzle is connected to the nozzle and is positioned facing the decorative paper.

[0011] Furthermore, the adjusting component includes a first motor, a cam, and an elastic element. The first motor is fixedly mounted on the bracket, the cam is fixedly mounted on the output shaft of the first motor, and the cam is used to abut against the fixed seat. The elastic element is mounted on the bracket, and the elastic element abuts against the fixed seat and is used to drive the fixed seat closer to the cam.

[0012] Furthermore, the elastic element includes a rubber block, and a fixing plate is fixedly disposed on the bracket on the side away from the cam, and the rubber block is fixedly disposed on the fixing plate.

[0013] Furthermore, a slide rail is fixedly installed on the bracket, and a pair of slide rails are arranged in parallel, with the fixing seat slidably connected to the slide rail.

[0014] Furthermore, a movable seat is slidably mounted on the bracket, and a cylinder is fixedly mounted on the bracket. The output shaft of the cylinder is fixedly connected to the movable seat. The cylinder can drive the movable seat to move along the decorative paper between the tension roller and the take-up roller. The nozzle is fixedly mounted on the movable seat.

[0015] Furthermore, a connecting rod is fixedly mounted on the movable seat, and an arc-shaped plate is fixedly mounted on the connecting rod. The arc-shaped plate is located on the other side of the nozzle relative to the decorative paper between the tension roller and the take-up roller, and the arched surface of the arc-shaped plate faces the decorative paper between the tension roller and the take-up roller.

[0016] Furthermore, the nozzles are arranged in a triangular pattern, and a pair of air guide plates are fixedly mounted on the movable base. The three nozzles are located within the pair of air guide plates, and the pair of air guide plates are open on one side facing the arc-shaped plate.

[0017] Furthermore, the driving component includes a second motor, which is a self-locking motor.

[0018] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0019] 1. This utility model, through the rational configuration of guide rollers, take-up rollers, tension rollers, and nozzles, effectively ensures that the decorative paper remains in a uniform and compact state throughout the winding process. The guide rollers guide the paper smoothly into the take-up rollers, while the tension rollers adjust the tension of the decorative paper to prevent loosening or wrinkling during winding, ensuring the paper's flatness and compactness. The nozzles spray airflow through nozzles to provide additional tension adjustment for the paper, effectively preventing air bubbles or misalignment during winding and improving the uniformity and stability of the winding process.

[0020] Furthermore, the adjustable tension roller enhances the device's versatility. The adjustable mechanism drives the fixed base to move back and forth along the direction away from or towards the take-up roller, continuously adjusting the paper tension. This design effectively improves winding efficiency, reduces manual intervention, and, through a dual control method of airflow and mechanical tension, allows for more precise control of the decorative paper's winding effect. The equipment has a compact structure, saves space, and demonstrates high stability and durability during long-term use, adapting to high-intensity production environments. It reduces operator dependence on the equipment, making the winding process more efficient and stable. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Example: The following is a reference Figures 1-4 As shown in the figure, and further explained with reference to specific embodiments, this embodiment provides a decorative paper winding device, including a bracket 1, which is made of aluminum profile or steel structure and has good load-bearing performance and stability.

[0029] Multiple guide rollers 11 are rotatably mounted on the support 1. These guide rollers 11 are arranged in parallel horizontally to guide the decorative paper through the paper sequentially, ensuring it remains taut and flat during operation. The guide rollers 11 are rotatably connected to the crossbeam of the support 1 via bearings. An anti-slip coating can be applied to the surface of the rollers to improve the guiding effect on the paper and prevent deviation.

[0030] The take-up roller 2 is mounted on the take-up end of the bracket 1 and is rotatably mounted on the bracket 1 via bearings. A drive unit 21 is fixedly mounted on the bracket 1. The drive unit 21 includes a second motor 211, which is a self-locking type used to maintain the position of the take-up roller 2 when the machine stops, preventing reverse rotation or unwinding due to inertia. The output shaft of the second motor 211 is coaxially connected to the input end of the take-up roller 2, using a coupling or pulley mechanism for transmission to ensure stable drive.

[0031] The tension roller 3 is rotatably mounted on a sliding fixed seat 31, which is mounted on the bracket 1 via a slide rail 6 assembly. The slide rails 6 are arranged in pairs in parallel, guiding the fixed seat 31 to slide back and forth in a direction away from or near the take-up roller 2. The tension roller 3 is used to cooperate with tension control during the winding process to ensure that the decorative paper is wound tightly.

[0032] Reference Figure 2 and Figure 3 As shown, the adjusting component 4 drives the fixed seat 31 containing the tension roller 3 to move along the slide rail 6, thereby achieving dynamic adjustment of the tension on the decorative paper. Specifically, the adjusting component 4 includes a first motor 41, a cam 42, and an elastic element 43. The first motor 41 is fixedly mounted on the bracket 1, and the cam 42 is fixedly connected to the output shaft of the first motor 41 and located directly above the contact block below the fixed seat 31. When the first motor 41 drives the cam 42 to rotate, the cam 42 abuts against the contact block, pushing the fixed seat 31 to move along the slide rail 6 in a direction away from or towards the take-up roller 2, thereby changing the paper tension between the tension roller 3 and the take-up roller 2 and achieving dynamic adjustment.

[0033] To ensure that the fixed seat 31 can be promptly reset when the motor stops or during the rotation gap of the cam 42, the adjusting component 4 also includes an elastic element 43 disposed on the opposite side of the cam 42. The elastic element 43 automatically pushes the fixed seat 31 back to its initial position when there is no external force or when the cam 42 rotates to a non-contact position. The elastic element 43 adopts a rubber block 431 structure, which is fixedly mounted on the fixing plate 12 on the bracket 1. While providing elastic restoring force, it also has a good shock absorption effect, helping to improve the stability and reliability of the adjustment process. In other embodiments, the elastic element 43 can also be replaced with other elastic components such as springs as needed.

[0034] To further improve the adhesion and uniformity of the decorative paper during the winding process, a nozzle assembly 5 is installed between the tension roller 3 and the winding roller 2. This nozzle assembly includes three nozzles 5 arranged in an equilateral triangle. The three nozzles 5 are connected to an air pump 53 via a connecting pipe 52, allowing for a stable air supply to the surface of the decorative paper. Several elongated nozzles 51 are evenly distributed on the surface of each nozzle 5, facing the decorative paper directly to achieve directional airflow, thus aiding in flattening and increasing adhesion.

[0035] In practical use, the airflow ejected by nozzle 51 can not only effectively straighten the paper surface and prevent wrinkles or deviations, but also spray specific media such as anti-sticking agents and antistatic agents as needed, effectively controlling the electrostatic adsorption of paper and improving the neatness of winding and the quality of finished products.

[0036] Reference Figure 3 As shown, to further enhance the effect of the nozzle 5 on the decorative paper, a movable seat 7 is slidably mounted on the bracket 1. The movable seat 7 can reciprocate on the slide rail 6 perpendicular to the direction of movement of the decorative paper. To achieve precise adjustment, a cylinder 71 is fixedly mounted on the bracket 1. The output shaft of the cylinder 71 is fixedly connected to the movable seat 7, which can drive the movable seat 7 to move closer to or further away from the decorative paper between the tension roller 3 and the take-up roller 2 in a linear motion.

[0037] The nozzle 5 is fixedly mounted on the movable base 7. As the movable base 7 moves, the distance between its nozzle 51 and the decorative paper can be flexibly adjusted. This structural design facilitates the adaptation of airflow of different intensities and angles according to different paper thicknesses, materials, or operating conditions, thereby more effectively controlling the additional tension of the paper through airflow and avoiding wrinkles, bubbles, or deviations caused by uneven tension during the winding process.

[0038] A pair of air guide plates 8 are welded or bolted to the movable base 7. The two air guide plates 8 are symmetrically installed on both sides of the nozzle 5 and extend along the axis of the nozzle 5. All three nozzles 5 are arranged between the air guide plates 8. The air guide plates 8 open towards the decorative paper side between the tension roller 3 and the take-up roller 2, forming a partially closed blowing airflow chamber, which can effectively concentrate the airflow ejected from the nozzle 51, enhance the direct force of the airflow on the paper surface, and reduce the diffusion loss of the airflow in the environment.

[0039] To further optimize the airflow distribution, a connecting rod 72 is fixedly welded to the movable base 7, and an arc-shaped plate 721 is fixedly welded to the distal end of the connecting rod 72. The arc-shaped plate 721 is located on the back side of the decorative paper path where the nozzle 5 is located, opposite to the direction of the nozzle 51, with its arched surface facing the decorative paper. By reflecting or guiding the airflow, the arc-shaped plate 721 constrains and strengthens the airflow area without contacting the paper, enhancing the tension control in the middle and edge areas of the paper, thereby further improving the uniformity and compactness of the winding.

[0040] In summary, the movable seat 7 driven by cylinder 71 enables the nozzle 5 assembly to be adjustable. In conjunction with the air guide plate 8 to concentrate the airflow and the arc plate 721 to guide the airflow, active intervention and dynamic adjustment of the force state of the decorative paper are achieved. This effectively solves the problems of paper bubbling, misalignment or loosening in the traditional winding process, and ensures that the decorative paper maintains a flat and tight winding state throughout the entire winding process.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
