Description

Technical Field

[0001] This utility model relates to the field of fabric rolling machine technology, and in particular to a fabric rolling machine with an anti-reverse rolling structure. Background Technology

[0002] A fabric rolling machine is used for rolling various fabrics, non-woven fabrics, foam, leather, paper, reflective materials, acetate cloth, reinforcing tape, conductive cloth, etc., into rounds for packaging and for repeated rolling before cutting and bundling various fabrics. It can roll into straight-weave or 45-degree twill fabrics, photoelectric edge alignment, and can effectively align and automatically control the code for materials of different thicknesses. The roll length can be set. The fabric rolling machine is an accessory of the circular knitting machine and is located below the circular knitting machine. When the fabric rolling machine is operating, the driven rolling roller rolls up the woven fabric from the circular knitting machine into a flat bundle of woven fabric. The fabric rolling machine mainly relies on three rolling rollers to achieve the above functions, with the middle rolling roller rotating relative to the two outer rolling rollers.

[0003] In the prior art, Chinese patent document CN 217996184 U proposes a fabric winding machine for preventing backwinding, including a main frame. An upper support is provided on the upper outer wall of the main frame, and the upper support is symmetrically distributed along the vertical center line of the main frame. A first electro-hydraulic rod is provided on the lower surface of the upper support, and four first electro-hydraulic rods are provided. When the machine backwinds, the equipment tube rotates counterclockwise with the fabric. The ratchet is locked by a locking tooth to prevent the equipment tube from rotating counterclockwise, thus preventing the fabric that has already been wound in the winding equipment from backwinding into the main frame, protecting the fabric already wound in the winding equipment, and reducing fabric loss. However, in actual use, the above solution lacks control over the problems of fabric deviation and loosening during the winding process, resulting in uneven tightness and uneven edges of the finished fabric roll, affecting subsequent processing and product quality. Especially under high-speed operation, if the fabric is not corrected in time, it is very easy for it to deviate or fold. Therefore, this utility model proposes a fabric winding machine with an anti-backwinding structure to meet the needs of achieving automatic deviation control of the fabric and effectively preventing backwinding, thereby improving the winding quality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a fabric winding machine with an anti-backwinding structure to solve the problems of fabric deviation and loosening during the winding process.

[0005] To achieve the above objectives, this utility model provides a fabric rolling machine with an anti-backwinding structure, comprising a support frame, a contact roller on one side of the inner wall of the support frame, a take-up roller on the inner wall of the support frame, limiting plates at both ends of the take-up roller, a drive motor inside the support frame, and a belt connected to the contact roller and the take-up roller fitted onto the output end of the drive motor. A second connecting rod and a first connecting rod are provided on the inner wall of the support frame, the second connecting rod being located above the take-up roller and the first connecting rod being located above the contact roller. A smoothing component is provided on the second connecting rod; multiple pressure components are provided on the first connecting rod. The smoothing component is used to smooth the fabric on the take-up roller during winding; the pressure components are used to tighten the fabric on the contact roller during winding.

[0006] Preferably, the smoothing component includes a first sleeve ring disposed on the second connecting rod, a first telescopic rod disposed on the first sleeve ring, the first telescopic rod being a telescopic structure, a contact arc plate disposed at one end of the first telescopic rod, a buffer spring sleeved on the first telescopic rod, one end of the buffer spring being disposed on the first sleeve ring, and the other end of the buffer spring being disposed on the contact arc plate, the contact arc plate being a semi-circular structure, the contact arc plate being able to contact the fabric on the surface of the take-up roller, and multiple sets of contact grooves being formed on the inner wall of the contact arc plate.

[0007] Preferably, the pressure assembly includes multiple sets of second sleeve rings disposed on the first connecting rod, a second telescopic rod disposed on the second sleeve ring, the second telescopic rod being a telescopic structure, a mounting plate disposed at one end of the second telescopic rod, a support spring sleeved on the second telescopic rod, one end of the support spring being disposed on the second sleeve ring, the other end of the support spring being disposed on the mounting plate, and rollers disposed on the inner wall of the mounting plate.

[0008] Preferably, the inner wall of the contact arc plate is made of rubber.

[0009] Preferably, the second connecting rod is rotatable on the inner wall of the support frame, and the diameter of the contact arc plate is larger than the maximum diameter of the take-up roller when it takes up the fabric.

[0010] Preferably, the roller is always in contact with the fabric, and multiple sets of vibration grooves are formed on the roller.

[0011] Preferably, the surface of the roller is coated with a rubber layer.

[0012] Preferably, one end of the take-up roller is provided with a central shaft, a rotating disk is provided on the central shaft, a stop pawl is provided on the rotating disk, and a ratchet is provided on the inner wall of the support frame, with the stop pawl engaging with the inner wall of the ratchet.

[0013] The beneficial effects of this utility model are:

[0014] 1. The drive motor drives the belt drive connected to the contact roller and the take-up roller to realize the winding movement of the fabric. After being pressed by multiple sets of pressure components on the contact roller, the fabric remains stable. By setting the pressure components, the fabric is stable and controlled when entering the contact roller, avoiding looseness or deviation. Then, the smoothing component acts on the take-up roller to smooth the wound fabric layer, ensuring that the fabric is neatly wound into the take-up roller, improving the quality of the finished product. At the same time, the limiting plate restricts the position of the fabric edge, and together with the entire guiding and pressing structure, effectively prevents the fabric from rolling back, wrinkling or shifting. This improves the stability and automation level of the equipment operation, and is suitable for fabric winding processes with strong continuity and high quality requirements.

[0015] 2. When the fabric is wound with the take-up roller, the contact arc plate approaches and contacts the outer layer of the fabric. Through the flexible contact between the contact arc plate and the fabric surface, the fabric surface is effectively smoothed during the winding process, avoiding wrinkles or local bulges, thus improving the quality of the rolled fabric. The contact arc plate has a semi-circular structure with a diameter larger than the maximum diameter of the rolled fabric. Multiple sets of contact grooves are set inside to enhance the smoothing contact effect. The contact surface is made of rubber material, which effectively adheres to the fabric surface. With the help of the elastic force of the buffer spring, the first telescopic rod cooperates with the buffer spring to achieve elastic adjustment, adapting to fabrics of different thicknesses or tensions, and is suitable for high-quality rolled fabric processes.

[0016] 3. During the fabric conveying process via the contact rollers, the rollers, under the action of spring force, consistently press against the fabric surface, achieving continuous contact and applying constant pressure. The vibration groove vibrates against the fabric surface during rolling, creating minute disturbances that help release local tension or air bubbles, improving fabric stability. It provides continuous and flexible pressure to the fabric during winding, preventing shaking, loosening, or deviation at the contact rollers. The support spring and the second telescopic rod work together to ensure the rollers remain in close contact with the fabric and adapt to materials of varying thicknesses. The roller surface is coated with rubber to enhance friction with the fabric and prevent damage. The vibration groove helps improve fabric uniformity and release excess tension, further enhancing winding stability and finished product quality.

[0017] 4. When the take-up roller rotates forward with the fabric, the stop pawl can smoothly slide over the ratchet teeth with the rotating disc; when the take-up roller attempts to rotate in the reverse direction, the stop pawl engages with the ratchet teeth, forming a mechanical block to prevent reverse rotation, thus achieving a unidirectional anti-backwinding function; through the cooperation of the stop pawl and the ratchet, a simple and efficient mechanical anti-backwinding function is achieved, which can stably prevent the take-up roller from reversing without an external control system. The structure has a fast response and high reliability, making it suitable for high-speed fabric winding operations; the stop mechanism relies on pure mechanical meshing, is highly durable, has low maintenance costs, and effectively improves the overall machine's operational stability and fabric winding quality.

[0027] like Figures 1-5 As shown, a fabric rolling machine with an anti-backwinding structure includes a support frame 1. A contact roller 2 is provided on one side of the inner wall of the support frame 1, and a take-up roller 3 is provided on the inner wall of the support frame 1. Limiting plates 5 are provided at both ends of the take-up roller 3. A drive motor 4 is provided inside the support frame 1. A belt connected to the contact roller 2 and the take-up roller 3 is sleeved on the output end of the drive motor 4. A second connecting rod 22 and a first connecting rod 21 are provided on the inner wall of the support frame 1. The second connecting rod 22 is located above the take-up roller 3, and the first connecting rod 21 is located above the contact roller 2. A smoothing component is provided on the second connecting rod 22. Multiple pressure components are provided on the first connecting rod 21. The smoothing component is used to smooth the fabric on the take-up roller 3 when it is being rolled up. The pressure components are used to tighten the fabric on the contact roller 2 when it is being rolled up.

[0028] The drive motor 4 drives the belt drive connected to the contact roller 2 and the take-up roller 3 to realize the winding movement of the fabric. After being pressed by multiple sets of pressure components on the contact roller 2, the fabric remains stable. By setting the pressure components, the fabric is stably controlled when entering the contact roller 2, avoiding loosening or deviation. Then, the smoothing component acts on the take-up roller 3 to smooth the winding fabric layer, ensuring that the fabric is neatly wound into the take-up roller 3, improving the quality of the finished product. At the same time, the limiting plate 5 restricts the position of the fabric edge, and together with the entire guiding and pressing structure, effectively prevents the fabric from rolling back, wrinkling or shifting. This improves the stability and automation level of the equipment operation, and is suitable for fabric winding processes with strong continuity and high quality requirements.

[0029] like Figure 1 , Figure 2 and Figure 4As shown, the smoothing component includes a first sleeve ring 10 disposed on the second connecting rod 22, a first telescopic rod 11 disposed on the first sleeve ring 10, the first telescopic rod 11 being a telescopic structure, a contact arc plate 13 disposed at one end of the first telescopic rod 11, a buffer spring 12 sleeved on the first telescopic rod 11, one end of the buffer spring 12 being disposed on the first sleeve ring 10, and the other end of the buffer spring 12 being disposed on the contact arc plate 13, the contact arc plate 13 being a semi-circular structure, the contact arc plate 13 being able to contact the fabric on the surface of the take-up roller 3, multiple sets of contact grooves 14 being formed on the inner wall of the contact arc plate 13; the inner wall of the contact arc plate 13 being made of rubber; the second connecting rod 22 being able to rotate on the inner wall of the support frame 1, and the diameter of the contact arc plate 13 being larger than the maximum diameter when the take-up roller 3 takes up the fabric;

[0030] When the fabric is wound with the take-up roller 3, the contact arc plate 13 approaches and contacts the outer layer of the fabric. Through the flexible contact between the contact arc plate 13 and the fabric surface, the fabric surface is effectively smoothed during the winding process, avoiding wrinkles or local bulges in the fabric layer and improving the quality of the rolled fabric. The contact arc plate 13 has a semi-circular structure with a diameter larger than the maximum diameter of the rolled fabric. Multiple sets of contact grooves 14 are provided inside to enhance the smoothing contact effect. The contact surface is made of rubber material, which effectively adheres to the fabric surface. With the help of the elastic force of the buffer spring 12, the first telescopic rod 11 cooperates with the buffer spring 12 to achieve elastic adjustment, adapting to fabrics of different thicknesses or tension states, which is suitable for the needs of high-quality rolled fabric processes.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the pressure assembly includes multiple sets of second sleeve rings 15 disposed on the first connecting rod 21. A second telescopic rod 16 is disposed on each second sleeve ring 15. The second telescopic rod 16 is a telescopic structure. A mounting plate 18 is disposed at one end of the second telescopic rod 16. A support spring 17 is sleeved on the second telescopic rod 16. One end of the support spring 17 is disposed on the second sleeve ring 15, and the other end is disposed on the mounting plate 18. A roller 19 is disposed on the inner wall of the mounting plate 18. The roller 19 is always in contact with the fabric. Multiple sets of vibration grooves 20 are formed on the roller 19. The surface of the roller 19 is coated with a rubber layer.

[0032] During the fabric conveying process via the contact roller 2, the roller 19, under the action of spring force, always presses against the fabric surface, achieving continuous contact and applying constant pressure. The vibration groove 20 vibrates against the fabric surface during rolling, creating minute disturbances that help release local tension or air bubbles, improving fabric stability. It provides continuous and flexible pressure on the fabric during the rolling process, preventing the fabric from shaking, loosening, or deviating at the contact roller 2. The support spring 17 and the second telescopic rod 16 work together to ensure that the roller 19 always adheres tightly to the fabric and adapts to materials of different thicknesses. The surface of the roller 19 is coated with rubber to enhance friction with the fabric and prevent damage. The vibration groove 20 helps improve fabric uniformity and release excess tension, further improving rolling stability and finished product quality.

[0033] like Figures 1-3 As shown, a central shaft 7 is provided at one end of the take-up roller 3, a rotating disk 8 is provided on the central shaft 7, a stop pawl 9 is provided on the rotating disk 8, and a ratchet 6 is provided on the inner wall of the support frame 1. The stop pawl 9 meshes with the inner wall of the ratchet 6.

[0034] When the take-up roller 3 rotates forward with the fabric, the stop pawl 9 can smoothly slide over the teeth of the ratchet 6 with the rotating disk 8. When the take-up roller 3 attempts to rotate in the reverse direction, the stop pawl 9 engages with the teeth of the ratchet 6, forming a mechanical block to prevent it from rotating in the reverse direction, thus achieving a unidirectional anti-backwinding function. Through the cooperation of the stop pawl 9 and the ratchet 6, a simple and efficient mechanical anti-backwinding function is achieved, which can stably prevent the take-up roller 3 from reversing without an external control system. The structure has a fast response and high reliability, making it suitable for high-speed fabric winding operations. The stop mechanism relies on pure mechanical meshing, making it durable, with low maintenance costs, and effectively improving the overall machine operation stability and fabric winding quality.
