Description

Technical Field

[0001] This application relates to the technical field of material winding, and in particular to a friction-type anti-slip winding device. Background Technology

[0002] In textile production and related industries, fabric winding is of paramount importance. Efficient and stable fabric winding can improve the continuity of the production process, reduce wrinkles and damage to fabrics during storage and transportation, thereby ensuring fabric quality and promoting the smooth operation of the entire textile industry chain.

[0003] In related technologies, fabrics are wound into cylinders after forming. When winding cotton, polyester, and linen fabrics, the fabric itself has texture, and the winding rollers mainly rotate to form the fabric. However, for fabrics with low surface friction coefficients, such as fiberglass, the winding rollers are prone to slippage, resulting in low winding density. In actual production, a more reliable, efficient fabric winding device that can effectively avoid slippage is needed. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a friction-type anti-slip winding device.

[0005] A friction-type anti-slip winding device, comprising: Mounting frame; A take-up roller is movably connected to the mounting frame for taking up fabric. The take-up roller is parallel to the mounting frame and can move up and down in a direction perpendicular to the mounting frame. The transmission device includes an auxiliary roller and a pulley assembly. The auxiliary roller is rotatably connected to the mounting frame and is arranged parallel to the side of the take-up roller. The pulley assembly is fixedly mounted on the mounting frame and located at one end of the take-up roller. The pulley assembly is used to drive the auxiliary roller to rotate. The take-up roller abuts against the auxiliary roller. The rotation of the auxiliary roller uses friction to drive the take-up roller to rotate and perform a winding action.

[0006] By adopting the above technical solution, the auxiliary roller can be driven to rotate using a pulley assembly. The friction between the auxiliary roller and the take-up roller drives the take-up roller to rotate, thereby achieving fabric take-up. At the same time, the take-up roller can move up and down along a direction perpendicular to the mounting frame, adapting to different take-up conditions. The gravity of the take-up roller keeps it in close contact with the auxiliary roller. The adaptive pressure enhances the stability of friction transmission, completely solving the problem of intermittent slippage caused by insufficient pressure in traditional take-up. When the thickness of the fabric changes, the real-time up and down movement of the take-up roller dynamically adjusts the contact pressure with the auxiliary roller, ensuring a constant friction transmission torque and avoiding tension fluctuations.

[0007] Preferably, it also includes a guide roller, which is rotatably connected to the mounting frame and located below the take-up roller. The guide roller is connected to the pulley assembly, and the guide roller cooperates with the auxiliary roller to give the fabric tension.

[0008] By adopting the above technical solution, the mounting frame is used to support the components. The take-up roller is movably connected to the mounting frame and can move up and down to take up the fabric. The auxiliary roller of the transmission device is rotatably connected to the mounting frame and parallel to the side of the take-up roller. The pulley assembly drives the auxiliary roller to rotate. The auxiliary roller drives the take-up roller to rotate and take up the fabric by friction. On this basis, a guide roller is added. The guide roller is rotatably connected to the mounting frame and located below the take-up roller and connected to the pulley assembly. The guide roller and the auxiliary roller cooperate to give the fabric tension.

[0009] Preferably, the pulley assembly includes a driving pulley, a first driven pulley, two second driven pulleys, and an auxiliary pulley. The driving pulley is connected to a drive motor. The driving pulley and the first driven pulley, the first driven pulley and the auxiliary pulley, and the auxiliary pulley and the second driven pulleys are all connected and driven by a belt. The first driven pulley is connected to the guide roller, and the second driven pulleys are connected to the auxiliary roller.

[0010] By adopting the above technical solution, the belt connection transmission can ensure stable power transmission between each wheel. The drive motor drives the drive wheel, which in turn drives the first driven wheel, the auxiliary wheel, and the second driven wheel to rotate in sequence via the belt. The first driven wheel drives the guide roller to rotate, and the second driven wheel drives the auxiliary roller to rotate. In this way, the auxiliary roller uses friction to drive the take-up roller to wind up the fabric, ensuring the stability and reliability of the entire winding device.

[0011] Preferably, the auxiliary roller includes a first support roller and a second support roller, the first support roller and the second support roller are respectively connected to the second driven wheel, and the surfaces of the first support roller and the second support roller are covered with a fabric with a high coefficient of friction.

[0012] By adopting the above technical solution, the take-up roller can abut against the auxiliary roller composed of the first support roller and the second support roller. When the pulley assembly drives the auxiliary roller to rotate, the high friction coefficient fabric wrapped on the surface of the first support roller and the second support roller can increase the friction between them and the take-up roller, thereby more effectively using the friction to drive the take-up roller to rotate and perform the winding action.

[0013] Preferably, it also includes an anti-reverse mechanism, which includes a ratchet coaxially connected to one of the second driven wheels and a latch that cooperates with the ratchet, the latch being movably connected to the mounting frame.

[0014] By adopting the above technical solution, the mounting frame can provide overall support, the take-up roller can move up and down and take up the fabric under the friction of the auxiliary roller, the pulley assembly drives the auxiliary roller to rotate, the auxiliary roller includes a first support roller and a second support roller and the surface is covered with a high friction coefficient fabric, and an anti-reverse mechanism is set on this basis, wherein the ratchet is coaxially connected to the second driven wheel, and the latch is movably connected to the mounting frame and cooperates with the ratchet, which can prevent the take-up roller from reversing and ensure the stability of the fabric take-up.

[0015] Preferably, the mounting frame is provided with fixing mechanisms at both ends. The fixing mechanisms include fixing rods mounted on the mounting frame and support rods arranged perpendicular to the fixing rods, and the take-up roller is slidably connected between the support rods.

[0016] By adopting the above technical solution, the fixing mechanism at both ends of the mounting frame can position and support the winding roller. The winding roller can slide between the support rods, which facilitates the winding roller to move up and down in a direction perpendicular to the mounting frame to adapt to changes during the winding process.

[0017] Preferably, the take-up roller is rotatably connected to sliding components at both ends, the support rod is a hollow structure with one open side, the sliding components are disposed inside the support rod, and the sliding components are used to drive the take-up roller to move along the length direction of the support rod.

[0018] By adopting the above technical solution, fixed rods and vertical support rods are set at both ends of the mounting frame. The take-up roller moves along its length through the hollow support rods at both ends via sliding components, enabling the take-up roller to move up and down and adapt to changes in the fabric winding process. In conjunction with the mounting frame, the take-up roller for winding the fabric, and the transmission device consisting of an auxiliary roller and a pulley assembly, the rotation of the auxiliary roller uses friction to drive the take-up roller to wind the fabric. Simultaneously, if a guide roller connected to the pulley assembly and located below the take-up roller is also provided, it can provide tension to the fabric. If the pulley assembly adopts a specific connection and transmission method of a driving wheel, a first driven wheel, two second driven wheels, and an auxiliary wheel, power transmission can be achieved. If the auxiliary roller includes a first support roller and a second support roller and its surface is covered with a high-friction coefficient fabric, it can enhance friction to drive the take-up roller.

[0019] By adopting the above technical solution, the mounting frame can serve as the mounting base for each component; the take-up roller is movably connected to the mounting frame to take up the fabric and can move up and down; the pulley assembly of the transmission device drives the auxiliary roller to rotate, and the auxiliary roller uses friction to drive the take-up roller to rotate to complete the take-up action; in the fixing mechanism at both ends of the mounting frame, the take-up roller is slidably connected between the support rods through the sliding assembly.

[0020] Preferably, the sliding assembly includes a guide rod and a sliding sleeve. The guide rod is arranged parallel to the support rod, and the sliding sleeve is sleeved on the guide rod and fixedly connected to both ends of the take-up roller.

[0021] By adopting the above technical solution, the take-up roller can move along the length of the support rod by sliding on the guide rod, so that the take-up roller can move up and down in a direction perpendicular to the mounting frame, thereby ensuring that the take-up roller can abut against the auxiliary roller and complete the winding action by using friction.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The take-up roller abuts against the auxiliary roller, and the rotation of the auxiliary roller uses friction to drive the take-up roller to rotate for the take-up action, avoiding the use of complex gear transmission mechanisms, reducing maintenance costs, and improving production continuity; 2. The guide roller and auxiliary roller work together to give the fabric tension, preventing problems such as wrinkles and uneven stacking of the fabric during the winding process; Attached Figure Description

[0025] The following will be combined with the appendix Figure 1-5The technical solutions in the embodiments of this utility model are described in further detail below. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0026] This application mainly addresses the winding of smooth fabrics, such as fiberglass fabrics. Due to the smoothness of the fabric itself, fiberglass fabrics tend to slip during winding, making it impossible to adjust the fabric tension and thus affecting the winding effect. This application mainly uses friction transmission to drive the winding roller to wind the fabric, thereby improving the winding stability and reliability. The following is a further detailed description of this application.

[0027] Example 1 refer to Figure 1 and Figure 2 The friction-type anti-slip winding device provided in this application includes a mounting frame 1, a take-up roller 2, and a transmission device 3. The take-up roller 2 is movably connected to the mounting frame 1, and the transmission device 3 is fixedly installed on the mounting frame 1. The take-up roller 2 is parallel to the mounting frame 1 and can move up and down in a direction perpendicular to the mounting frame 1. The transmission device 3 includes an auxiliary roller 31 and a pulley assembly 32. The auxiliary roller 31 is rotatably connected to the mounting frame 1 and is arranged parallel to the side of the take-up roller 2. The pulley assembly 32 is located at one end of the take-up roller 2 and is used to drive the auxiliary roller 31 to rotate. The take-up roller 2 abuts against the auxiliary roller 31. The rotation of the auxiliary roller 31 uses friction to drive the take-up roller 2 to rotate for winding.

[0028] Specifically, the mounting frame 1 serves to support and secure other components. It can be made of metal materials, such as steel or aluminum alloy, which possess sufficient strength and rigidity to withstand various forces during the winding process. The mounting frame 1 can be a rectangular frame structure, assembled through welding or bolting. Alternatively, it can be integrally molded using a casting process, which improves the overall strength and stability of the mounting frame 1.

[0029] refer to Figure 2 The mounting frame 1 has fixing mechanisms 7 at both ends. The fixing mechanism 7 includes a fixing rod 71 mounted on the mounting frame 1 and a support rod 72 perpendicular to the fixing rod 71. The take-up roller 2 is slidably connected between the support rods 72. The fixing rod 71 and the support rod 72 can be made of metal tubing, such as steel or aluminum tubing, and are fixed to the mounting frame 1 by welding or bolting.

[0030] refer to Figures 2-4Specifically, the support rod 72 is a hollow structure with one open side. Sliding components 73 are rotatably connected to both ends of the take-up roller 2. The sliding components 73 are located inside the support rod 72 and are used to drive the take-up roller 2 to move along the length of the support rod 72. Specifically, combined with... Figure 5 The sliding assembly 73 includes a guide rod 734 and a sliding sleeve 735. The guide rod 734 is arranged parallel to the support rod 72. The sliding sleeve 735 is sleeved on the guide rod 734 and fixedly connected to both ends of the take-up roller 2 through a bearing sleeve 736. The sliding sleeve 735 is a linear bearing. (Reference) Figure 2 and Figure 3 The auxiliary roller 31 in the transmission device 3 includes a first support roller 311 and a second support roller 312, which are respectively connected to the pulley assembly 32. The surfaces of the first support roller 311 and the second support roller 312 are covered with a high-friction-coefficient fabric, such as rubber or polyurethane. This fabric can increase the friction between the auxiliary roller 31 and the take-up roller 2, ensuring that the auxiliary roller 31 can reliably drive the take-up roller 2 to rotate. The auxiliary roller 31 is rotatably connected to the mounting frame 1 via bearings to ensure its rotational flexibility. The pulley assembly 32 includes a drive pulley 321, a first driven pulley 322, two second driven pulleys 323, and an auxiliary pulley 324. The drive pulley 321 is connected to a drive motor 325, which can be an AC motor or a DC motor, with appropriate power and speed selected according to actual needs. The driving pulley 321 is connected to the first driven pulley 322, the first driven pulley 322 is connected to the auxiliary pulley 324, and the auxiliary pulley 324 is connected to the second driven pulley 323 via belts. This transmission method features high transmission efficiency and accurate transmission ratio. Chain drive can also be used. The first driven pulley 322 is connected to the guide roller 4, and the second driven pulley 323 is connected to the auxiliary roller 31. Through the transmission of the pulley assembly 32, the power of the drive motor 325 is transmitted to the auxiliary roller 31 and the guide roller 4.

[0031] refer to Figure 2 The device also includes a guide roller 4, which is rotatably connected to the mounting frame 1 and located below the take-up roller 2. The guide roller 4 is connected to the pulley assembly 32, and cooperates with the auxiliary roller 31 to apply tension to the fabric. The guide roller 4 can have a similar structure to the take-up roller 2, and its surface can be smoothed to reduce friction between the fabric and the guide roller 4. The guide roller 4 is connected to the mounting frame 1 via bearings to ensure its flexible rotation. The connection between the guide roller 4 and the pulley assembly 32 can be achieved using a key connection or a coupling, ensuring reliable power transmission.

[0032] refer to Figure 2 and Figure 3This device also includes an anti-reverse mechanism 6, which comprises a ratchet 61 coaxially connected to one of the second driven wheels 323 and a latch 62 that engages with the ratchet 61. The latch 62 is movably connected to the mounting frame 1. The engagement of the ratchet 61 and the latch 62 prevents the take-up roller 2 from reversing when it stops rotating, ensuring the stability of the fabric winding. The ratchet 61 can be made of steel and its surface is hardened to improve its hardness and wear resistance. The latch 62 can be made of an elastic material, such as spring steel, to ensure that it can reliably engage with the ratchet 61.

[0033] Under the influence of gravity, the take-up roller 2 always stays close to the auxiliary roller 31, and its vertical movement range is orthogonal to the axis of the auxiliary roller 31, so that the pressure direction of the take-up roller 2 on the auxiliary roller 31 is consistent with the direction of friction transmission force. When the fabric roll diameter increases, the take-up roller 2 automatically moves upward, and the gravity component decreases, resulting in a decrease in pressure. At this time, the high-friction fabric on the surface of the auxiliary roller 31 increases the contact area through deformation, compensates for the pressure loss, and maintains a constant friction driving torque.

[0034] The implementation principle of this embodiment is as follows: This friction-type anti-slip winding device drives the auxiliary roller 31 to rotate through the pulley assembly 32. The auxiliary roller 31 uses friction to drive the take-up roller 2 to rotate for fabric winding. The guide roller 4 cooperates with the auxiliary roller 31 to give the fabric tension, improving the quality of fabric winding. The anti-reverse mechanism 6 can prevent the take-up roller 2 from reversing, ensuring the safety of fabric winding. The mounting frame 1 and the fixing mechanism 7 provide a stable support structure for the entire device. The sliding assembly 73 allows the take-up roller 2 to move flexibly, ensuring that the movement trajectory of the take-up roller 2 is strictly perpendicular to the mounting frame 1, eliminating the radial runout of the take-up roller 2, and avoiding uneven friction contact surface (such as one-sided wear) caused by gaps in traditional hinged structures.

[0035] Example 2 refer to Figure 5 The difference between this embodiment and the previous embodiment is that the sliding assembly 73 includes a guide rod 734 and a sliding sleeve 735. The guide rod 734 is arranged parallel to the support rod 72. The sliding sleeve 735 is sleeved on the guide rod 734 and fixedly connected to both ends of the take-up roller 2 by a bearing sleeve 736. The sliding sleeve 735 and the bearing sleeve 736 are arranged perpendicularly and integrally connected. The bearing sleeve 736 is sleeved on both ends of the take-up roller 2 and is a ball bearing. The guide rod 734 can be a smooth metal rod, such as a stainless steel rod, to reduce the frictional resistance between the sliding sleeve 735 and the guide rod 734. The sliding sleeve 735 is a linear bearing, which has good wear resistance and self-lubricating properties. This sliding assembly 73 has a simple structure, is easy to install, and can effectively drive the take-up roller 2 to move along the length of the support rod 72.

[0036] The implementation principle of this embodiment is as follows: Compared with Embodiment 1, the sliding assembly 73 of this embodiment adopts the structure of guide rod 734 and sliding sleeve 735, which can also realize the movement of the take-up roller 2 along the length direction of support rod 72. This sliding assembly 73 has lower cost and higher reliability, and is more suitable for some occasions with high cost and maintenance requirements.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
