Description

Technical Field

[0001] This application relates to the field of winding device technology, and more particularly to a self-tightening winding device for carpets. Background Technology

[0002] In existing technologies, carpet winding operations typically rely on manually controlled screws to adjust the position of the rollers contacting the carpet to achieve tension. However, this method has significant drawbacks: the tension adjustment response is slow, failing to adjust in a timely manner according to the actual tightness of the carpet. This can lead to the carpet becoming either too loose or too tight during winding, affecting the winding effect and carpet quality. Furthermore, existing equipment is poorly adaptable to carpets of different widths, often requiring frequent manual intervention to adjust the winding position, thus reducing work efficiency. Utility Model Content

[0003] The problem this application aims to solve is that existing carpets typically rely on manually controlled screws to adjust the position of the rollers that contact the carpet during the winding process. However, the response speed of the tension adjustment cannot be adjusted in time according to the actual tightness of the carpet, which may result in the carpet becoming loose or overly tight during the winding process.

[0004] To address the aforementioned technical problems, this application provides a self-tightening winding device for carpets, comprising a frame, with a vertical plate arranged at one end of the upper part of the frame, and a tensioning component arranged between the vertical plates that can adaptively tension the carpet according to its tightness. A winding component is also arranged on one side of the frame that can adjust the winding position according to the width of the carpet. The tensioning component includes a traction member for initial tensioning and laying of the carpet and a self-tightening member for adaptive tension adjustment of the carpet during winding. The traction member is located at the center line of the upper part of the vertical plate along its length, and the self-tightening members are symmetrically arranged on both sides of the traction member.

[0005] Because the self-tightening winding device of this application is designed with a tensioning component and a winding component, it can adaptively adjust the tension according to the tightness of the carpet through the tensioning component, and adjust the winding position according to the width of the carpet through the winding component. This solves the problem that in the prior art, carpets usually rely on manually controlled screws to adjust the position of the rollers that contact the carpet during the winding operation. However, the response speed of the tension adjustment cannot be adjusted in time according to the actual tightness of the carpet, which may cause the carpet to become loose or overly tight during the winding process.

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0015] This application relates to a self-tightening winding device for carpets, such as... Figure 1-7 As shown, the winding assembly 1 includes a frame 2, uprights 4, a tensioning assembly 3, and a winding assembly 1. The frame 2 serves as a basic support, with uprights 4 arranged at one of its upper ends. The tensioning assembly 3 is arranged between the uprights 4. This tensioning assembly 3 can adaptively tension the carpet according to its tightness. Unlike the manual control screw in the prior art, the tensioning assembly 3 of this invention adopts an adaptive adjustment method to achieve timely and accurate tension adjustment of the carpet. The winding assembly 1 is also arranged on one side of the frame 2. This winding assembly 1 can adjust the tension according to the width of the carpet. The winding position adjustment operation is performed. The winding component 1 adopts an adjustable design, which allows it to move horizontally to adapt to carpets of different widths. At the same time, the winding component 1 also works in conjunction with the tensioning component 3 to ensure that the carpet maintains appropriate tension during the winding process. Through the combination of the winding component 1 and the tensioning component 3, the present invention can perform effective self-tightening winding operations on carpets of various widths. This design not only improves winding efficiency but also ensures the flatness and tightness of the carpet during the winding process, thereby improving the overall quality of the carpet.

[0016] Tensioning assembly 3 includes a traction component and a self-tightening component. The traction component is mainly responsible for the initial tension and laying of the carpet, while the self-tightening component is responsible for adaptive tension adjustment of the carpet during use. The traction component includes a winding roller 13 and a first motor 12. The winding roller 13 is horizontally mounted on the top of the upright plate 4 via a bearing seat 5, located at the center line of the upper length direction of the upright plate 4. The first motor 12 is arranged on the outer side of one end of the upright plate 4 and connected to the winding roller 13 to drive the winding roller 13 to rotate, thereby realizing the laying of the carpet. The tensioning and self-tensioning components are a combination of sprockets 14, chains 15, float rollers 17, and springs 16 symmetrically arranged on both sides of the traction component. The sprockets 14 are vertically and symmetrically arranged on the upper part of the upright plate 4. The chains 15 are wound around the sprockets 14. To maintain effective tension of the chains 15 and adaptively adjust the carpet tension, springs 16 (in a stretched state) and float rollers 17 (for tensioning the carpet) are connected in series at the upper part of the chains 15. With increased use, the chains 15 may loosen. In this case, the springs 16 and float rollers 17 are connected in series. The spring 16 on the chain 15 will tighten inward under its preload, ensuring that the total path length formed by the spring 16 and the chain 15 around the sprocket 14 is constant. In this way, the float roller 17 can always apply a constant and vertically downward traction force to the carpet. The float roller 17 applies tension to the carpet by its own weight and rolls back and forth around the sprocket 14 through the chain 15, thereby achieving adaptive tension adjustment of the carpet. This design not only simplifies the structure but also improves the flexibility and adaptability of the carpet tensioning device. In practical applications, the first motor 12 drives the roller 13 to rotate, laying the carpet in the desired position and achieving initial tension through the traction component. Then, the self-tightening component begins to play its role. When the carpet becomes loose, the float roller 17 will descend under the action of gravity, pulling the chain 15 and the spring 16. Since the spring 16 is in a stretched state, it will automatically tighten, thereby adjusting the tension of the carpet. This adaptive adjustment mechanism ensures that the carpet always maintains an appropriate tension.

[0017] The winding assembly 1 includes a base 8, a second motor 7, an air shaft 6, a bearing seat 5, a guide post 11, a slider 10, and a third motor 9. The base 8 is stably positioned on the upper part of the frame 2, providing a stable support platform for the entire winding assembly 1. The second motor 7 is mounted on one end of the upper part of the base 8 via the bearing seat 5. This motor is the power source driving the rotation of the air shaft 6. The end of the second motor 7 is tightly connected to the air shaft 6. When the motor starts, the air shaft 6 rotates accordingly, thereby realizing the winding operation of the carpet. To ensure the stability of the air shaft 6 during rotation, a bearing seat 5 is specially provided on the upper part of the frame 2. This bearing seat 5 can fix one end of the air shaft 6, effectively preventing it from shaking or shifting during high-speed rotation. Below, sliders 10 are symmetrically arranged. These sliders 10 are fitted and slidably connected to guide posts 11 symmetrically arranged on the upper part of the frame 2. This design allows the base 8 to slide smoothly back and forth along the guide posts 11 under the drive of the third motor 9. This sliding function plays a key role in the carpet winding process. It can adjust the distance between the air shaft 6 and the carpet as needed, thereby ensuring that the carpet can be wound evenly and flatly onto the air shaft 6. The third motor 9 is an electric lead screw composed of servo motors. It is connected to the base 8 and is responsible for driving the base 8 to slide back and forth. The precise control capability of the servo motor allows the sliding distance and speed of the base 8 to be precisely adjusted, thereby meeting the winding needs of carpets of different lengths and thicknesses.

[0018] In use, the user guides the carpet through the chain roller, float roller 17, winding roller 13, and air shaft between the sprockets 14. The first motor 12 then pulls the winding roller 13 to rotate, causing the carpet covering its surface to move at a uniform and linear speed. The float roller 17, located on the chain 15, uses its own weight to raise and lower, allowing for adaptive tensioning of the carpet. Since the chain 15 may slack during use, the spring 16 connected to the upper part of the chain 15, which is in a pre-tensioned state during installation, contracts adaptively as the chain 15 length increases due to the reduced external tension. This ensures that the track length formed by the chain 15 and spring 16 around the chain 15 is not... The floating roller 17 rotates around the chain 15, and under the drive of the carpet, it performs vertical lifting and adaptive motion. As the floating roller 17 adapts to the lifting and lowering of the carpet, it can perform timely and effective tension adjustment of the carpet. Then, the second motor 7 drives the air shaft to perform the winding and coiling operation of the carpet. At the same time, as the width of the carpet changes significantly with different models, the third motor 9 pushes the base 8 to move horizontally along the guide post 11 on the upper part of the frame 2 via the slider 10, so that the retaining ring on the upper part of the air shaft 6 can abut against the edge of the carpet. This allows for effective positioning and winding of carpets of various sizes. The arrangement of the air shaft 6 can be matched with the bearing seat 5 to facilitate loading and unloading operations before and after the carpet is wound.
