Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a roller structure for an anti-tangling fiber opening machine in a nonwoven fabric production line. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth or non-woven material, is a sheet, web, or mat made of fibers arranged in a directional or random manner, bonded together through friction, cohesion, or adhesion, or a combination of these methods. Nonwoven fabrics are characterized by moisture resistance, breathability, flexibility, light weight, non-flammability, easy decomposition, non-toxicity, non-irritation, rich colors, low price, and recyclability.

[0003] During use, yarn is prone to sudden changes in tension due to stretching. Traditional roller structures use the lower roller to tension the yarn while the upper roller is fixed on top of the lower roller to hold the yarn in place. However, when the yarn experiences sudden changes in tension, the roller structure cannot tighten the yarn in time.

[0004] To address the aforementioned problems, existing technologies provide a solution. For example, patent publication number CN221988756U provides a roller structure for a doubling machine, including a frame, a lower roller, an upper roller, a pressing roller, and a lower pressure plate. The pressing roller and the lower pressure plate are connected by a transmission mechanism. When the pressing roller descends, the lower pressure plate descends linearly through the transmission mechanism. When the pressing roller rises, the lower pressure plate rises linearly through the transmission mechanism. A compression spring is provided below the lower pressure plate, and a lower pressure block is installed at the lower end of the compression spring. The lower pressure block is used to press down on the upper roller to limit its rotation. When the yarn is slack, the pressure roller drives the lower pressure block to descend, thus pressing down on the upper roller and reducing the yarn feeding speed, allowing the yarn to gradually transition from a slack state to a normal state. When the yarn is tensioned, the pressure roller drives the lower pressure block to rise, thus reducing the pressure on the upper roller and increasing the yarn feeding speed, allowing the yarn to gradually transition from a tensioned state to a normal state. The transmission mechanism uses a lever structure for transmission, which has high sensitivity in adjusting yarn tension and can reduce the slack range of the yarn to a smaller range. Although the existing device can self-adjust according to the yarn tension, fibers adhere to the roller during use. The presence of these fibers can easily cause unevenness on the roller surface, which can cause the yarn to fluctuate as it passes through the roller, resulting in changes in yarn tension and potentially causing deviations in yarn production.

[0005] To address this, a roller structure for an anti-tangling fiber opening machine in a nonwoven fabric production line is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a roller structure for an anti-tangling fiber opening machine in a nonwoven fabric production line, thereby solving the above-mentioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A nonwoven fabric production line includes an anti-tangling fiber opening machine roller structure, comprising a storage tank, a slider, a drive mechanism, an upper roller, a scraper, a cross rack, a cleaning mechanism, a cleaning scraper, a lower roller, and a fixed roller. The slider is connected to the storage tank, the drive mechanism is connected to the slider, the upper roller, the scraper, and the cross rack are all connected to the drive mechanism, the cleaning mechanism is connected to the cross rack, the cleaning scraper is connected to the cleaning mechanism, and the lower roller and the fixed roller are both connected to the storage tank. After the upper roller loses the upward pressure of the yarn, the slider descends and drives the scraper to clean the fibers on the upper roller through the drive mechanism. While the scraper is cleaning the fibers, the cross rack controls the operation of the cleaning mechanism and cleans the fibers on the scraper through the cleaning scraper.

[0008] Preferably, the driving mechanism includes a slide rod, a telescopic spring, a main gear, a secondary gear, a guide block, a guide rod, a screw, a threaded block, and a crossbar. The slide rod is fixedly connected to the storage tank. The telescopic spring is fixedly installed between the slide rod and the storage tank. The main gear is rotatably installed at one end of the slide rod. The secondary gear meshes with the main gear. The guide block is rotatably installed at one end of the secondary gear. The guide rod is slidably connected to the guide block. The screw is fixedly installed at one end of the secondary gear. The threaded block is threadedly connected to the screw. The crossbar is fixedly connected to the guide block.

[0009] Preferably, the storage tank has a sliding groove and a guide groove inside, the sliding groove and the guide groove have the same length, the sliding rod, the slider and the telescopic spring are all installed in the sliding groove, and the guide block and the guide rod are all installed in the guide groove.

[0010] Preferably, the gear ratio between the secondary gear and the primary gear is 1:5.

[0011] Preferably, the crossbar has a threaded groove inside, and both the screw and the threaded block are installed in the threaded groove. Multiple sets of threaded blocks are arranged at equal intervals.

[0012] Preferably, one end of the scraper blade is arc-shaped, and the surface of the scraper blade corresponding to the upper roller is provided with anti-slip texture made of rubber material, and the anti-slip texture is perpendicular to the crossbar.

[0013] Preferably, the cleaning mechanism includes a drive gear, a rotating rod, and a turntable. The drive gear meshes with a horizontal rack. The rotating rod is fixedly installed at one end of the drive gear, the turntable is fixedly installed at one end of the rotating rod, and the cleaning scraper is fixedly connected to the turntable.

[0014] Preferably, the scraper blade has a transverse groove inside, and the transverse groove is arranged perpendicular to the anti-slip texture.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By controlling the rotation of the upper roller, multiple sets of scraper blades are reciprocated to clean the fibers on the upper roller. At the same time, the cleaning scraper blades collect the fibers obtained by the scraper blades from cleaning the upper roller, which can prevent fibers from adhering to the upper roller for a long time, ensure the flatness of the upper roller, and thus ensure that the yarn maintains a relatively stable tension during the conveying process, thereby improving the quality of nonwoven fabric production.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0019] Reference Figures 1 to 7A roller structure for an anti-tangling fiber opening machine in a nonwoven fabric production line includes a storage tank 1 with a discharge port at one end, facilitating the movement of yarn into the opening machine. It also includes a slider 2, a drive mechanism 3, an upper roller 4, a scraper blade 5, a horizontal rack 6, a cleaning mechanism 7, a cleaning scraper blade 8, a lower roller 9, and a fixed roller 10. The slider 2 is connected to the storage tank 1, the drive mechanism 3 is connected to the slider 2, the upper roller 4, the scraper blade 5, and the horizontal rack 6 are all connected to the drive mechanism 3, the cleaning mechanism 7 is connected to the horizontal rack 6, and the cleaning scraper blade... 8 is connected to the cleaning mechanism 7. The lower roller 9 and the fixed roller 10 are both connected to the storage tank 1. The scraper 5 is set above the upper roller 4. With the above arrangement, the scraper 5 can avoid affecting the yarn conveying when cleaning the fibers on the upper roller 4, and can avoid yarn breakage. After the upper roller 4 loses the upward pressure of the yarn, the slider 2 descends and drives the scraper 5 to clean the fibers on the upper roller 4 through the drive mechanism 3. When the scraper 5 is cleaning the fibers, the horizontal rack 6 controls the operation of the cleaning mechanism 7 and cleans the fibers on the scraper 5 through the cleaning scraper 8.

[0020] As one embodiment of this utility model, refer to Figures 4 to 7The drive mechanism 3 includes a slide rod 31, a telescopic spring 32, a main gear 33, a secondary gear 34, a guide block 35, a guide rod 36, a screw 37, a threaded block 38, and a crossbar 39. The slide rod 31 is fixedly connected to the storage tank 1. The telescopic spring 32 is fixedly installed between the slider 2 and the storage tank 1. The telescopic spring 32 has low elasticity. The above arrangement ensures that the slider 2 is pushed while the yarn is tensioned. The main gear 33 is rotatably installed at one end of the slider 2, and the secondary gear 34 meshes with the main gear 33. Guide block 35 is rotatably mounted on one end of secondary gear 34. Guide rod 36 is slidably connected to guide block 35. Screw 37 is fixedly mounted on one end of secondary gear 34. Threaded block 38 is threadedly connected to screw 37. Crossbar 39 is fixedly connected to guide block 35. Slide groove 310 and guide groove 311 are respectively provided inside storage tank 1. The lengths of slide groove 310 and guide groove 311 are the same. Slide rod 31, slider 2, and telescopic spring 32 are all installed in slide groove 310. Guide block 35 and guide rod 36 are all installed in guide groove 310. Within the guide groove 311, the guide block 35 can move easily. The gear ratio between the secondary gear 34 and the primary gear 33 is 1:5. This configuration allows the secondary gear 34 to rotate rapidly, thereby enabling the threaded block 38 to reciprocate quickly. This improves the cleaning efficiency of the scraper blade 5 on the upper roller 4. The crossbar 39 has a threaded groove 312 inside, and both the screw 37 and the threaded block 38 are installed within the threaded groove 312. This design provides space for the movement of the screw 37 and the threaded block 38. Multiple sets of threaded blocks 38 are equidistantly arranged. One end of the scraper 5 is arc-shaped. This design prevents the scraper 5 from damaging the upper roller 4 when it reciprocates to clean the fibers on the upper roller 4. The scraper 5 and the upper roller 4 have anti-slip textures made of rubber on their corresponding surfaces. The anti-slip textures are perpendicular to the crossbar 39. This design facilitates the scraper 5 in cleaning the fibers adhering to the upper roller 4.

[0021] As one embodiment of this utility model, refer to Figure 7 The cleaning mechanism 7 includes a drive gear 71, a rotating rod 72, and a turntable 73. The drive gear 71 meshes with a horizontal rack 6. The rotating rod 72 is fixedly installed at one end of the drive gear 71, and the turntable 73 is fixedly installed at one end of the rotating rod 72. The cleaning scraper 8 is fixedly connected to the turntable 73. The scraper 5 has a horizontal groove 74 inside. Through the above arrangement, space can be provided for the movement of the cleaning scraper 8. The horizontal groove 74 is set perpendicular to the anti-slip texture. Through the above arrangement, the cleaning scraper 8 can easily clean the fibers adhering to the upper roller 4 when the scraper 5 is cleaning.

[0022] Working principle: During operation, the user connects the storage bin to the opening machine, then places one end of the yarn on the surfaces of the fixed roller 10 and the lower roller 9. When the opening machine starts, it conveys the yarn. The upper roller 4 is always rotating. If the yarn becomes slightly loose during conveying, the elasticity of the extension spring 32 will cause the slider 2 to slide downwards on the slide bar 31. As the slider 2 slides, it causes the crossbar 39 to slide down synchronously. The crossbar 39's descent causes the upper roller 4 to descend synchronously. Since the upper roller 4 is constantly rotating under its own power, it drives the main gear 33 to rotate. When roller 33 rotates, it drives the secondary gear 34 to rotate. When the secondary gear 34 rotates, it drives the screw 37 to rotate. When the screw 37 rotates, it drives multiple sets of scraper blades 5 to reciprocate through the threaded block 38, thereby cleaning the fibers adhering to the upper roller 4. When the scraper blades 5 move, they drive the drive gear 71 to mesh with the horizontal rack 6, thereby driving the drive gear 71 to rotate. When the drive gear 71 rotates, it drives the turntable 73 to rotate through the rotating rod 72. When the turntable 73 rotates, it drives the cleaning scraper blade 8 to clean the fibers on the scraper blades 5, thereby improving the cleaning effect of the scraper blades 5.
