Description

Technical Field

[0001] The invention relates to the technical field of fiber winding, in particular to a winding device for producing flat metachromatic ultra-bright DTY fibers. Background Art

[0002] Flat metachromatic superbright DTY fiber is a chemical fiber with special properties and appearance. It is usually produced by melt spinning technology. After the fiber is produced, it needs to be wound up by a fiber winder. The existing winder is usually equipped with two winding rollers, which can realize continuous winding operation without stopping the machine. After the reel on the first winding roller is fully wound, the side of the second winding roller is used to clamp the fiber (the winding roller will give the fiber bundle a horizontal clamping force during the clamping process), and the fiber between the two winding rollers is cut by a blade. As the second winding roller rotates, the fiber The fiber bundle is wound onto the surface of the drum on the second winding roller, so that a continuous winding operation is achieved. Since the fiber bundle produced by the melt spinning technology is composed of multiple fiber filaments, when the fiber bundle is clamped by the side of the winding roller, the fiber bundles will be stacked on each other, resulting in different forces on different fiber filaments in the same fiber bundle. Since the fiber bundle has tension during the winding process, the friction between the fiber filaments is uneven, causing the fiber filaments to move relative to each other, resulting in different tensions of the fiber filaments in the fiber bundle, which affects the subsequent winding and the quality of the finished product.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0018] A winding device for producing flat metachromatic ultra-bright DTY fibers, please refer to Figure 1-Figure 7 , comprising: a main body 1, on which a rotating disk 2 is installed, on which two mounting members 3 are rotatably and slidably connected; two transmission shafts 4, which are respectively rotatably connected to adjacent mounting members 3, and the transmission shaft 4 is fixedly connected to a tensioning shaft 5, and the tensioning shaft 5 is used to fix the reel 100; two first supporting rollers 6, which are respectively rotatably connected to adjacent mounting members 3, and the mounting members 3 are slidably connected to a first L-shaped member 7 at a position close to the first supporting roller 6, and the first L-shaped member 7 is extruded and matched with the first supporting roller 6, and an extrusion member 8 is slidably connected to a side of the mounting member 3 away from the tensioning shaft 5, and the extrusion member 8 and the first L-shaped member 7 are jointly fixedly connected to a first elastic sheet 9; two power assemblies, both arranged on a side of the rotating disk 2 away from the tensioning shaft 5, and the power assemblies are used to provide power to the adjacent extrusion members 8 and the adjacent transmission shaft 4.

[0019] The above scheme aims to solve the problem that when the fiber bundle is wound up by the existing winding machine, the tension of each fiber filament in the fiber bundle is different due to the different forces on different fiber filaments; the present scheme uses the first support roller 6 and the first L-shaped member 7 to squeeze and fix the fiber filaments, maintain the state of the fiber bundle when it is wound up on the reel 100, prevent the fiber filaments in the fiber bundle from stacking, and thus ensure that the forces on each fiber filament are consistent, and prevent the problem of different tensions of each fiber filament in the same fiber bundle; the main body 1 is provided with a guide component for changing the winding position of the fiber bundle on the surface of the reel 100; the first support roller 6 is A smooth metal material is used to reduce the resistance encountered by the fiber bundle when it slides on it, and to maintain the arrangement of the fiber filaments on the fiber bundle; a rubber pad is provided on the side of the first L-shaped member 7 close to the first supporting roller 6, and is used to deform the rubber pad and increase the contact area between the first L-shaped member 7 and the fiber filaments when the first L-shaped member 7 squeezes the first supporting roller 6; the first elastic sheet 9 is made of elastic metal material, and when the extrusion member 8 moves forward, the first elastic sheet 9 can pull the first L-shaped member 7 to move in the direction close to the central axis of the mounting member 3, and when the extrusion member 8 moves backward and resets, the first elastic sheet 9 can push the first L-shaped member 7 to move and reset.

[0020] Please refer to Figure 7 and Figure 8 The first supporting roller 6 is fixedly connected with an elastic ring 10, the diameter of the elastic ring 10 is larger than the diameter of the first supporting roller 6, and the elastic ring 10 is extruded and fitted with the first L-shaped member 7; there is friction between the extrusion member 8 and the mounting member 3, and the friction force between the extrusion member 8 and the mounting member 3 is larger than the elastic force of the elastic ring 10.

[0021] In the above scheme, the elastic ring 10 is used to limit the fiber bundle to prevent the fiber bundle from moving to the end of the first support roller 6; the elastic ring 10 can be made of rubber or silicone. After the fiber bundle contacts the first support roller 6, the fiber bundle drives the first support roller 6 to rotate through friction. Then, when the first L-shaped member 7 moves in the direction close to the central axis of the mounting member 3, the first L-shaped member 7 first contacts the elastic ring 10 and squeezes the elastic ring 10 to deform. Then, the first L-shaped member 7 contacts the first support roller 6, and the first L-shaped member 7 relies on the squeezing force to stop the rotation of the first support roller 6. At the same time, the first L-shaped member 7 uses the deformation of the elastic ring 10 to further enhance the limiting effect on the first support roller 6, improve the stability of the first support roller 6, and complete the clamping and fixing of the fiber bundle; at the same time, when the first L-shaped member 7 contacts the first support roller 6 and clamps the fiber bundle, the friction between the squeezing member 8 and the mounting member 3 is used to maintain the clamping force of the first L-shaped member 7 and the first support roller 6 on the fiber bundle.

[0022] Please refer to Figure 4-Figure 8 A shielding ring 11 is fixedly connected to the expansion shaft 5 near the mounting member 3 , and the outer diameter of the shielding ring 11 gradually decreases in the direction from the expansion shaft 5 to the mounting member 3 .

[0023] In the above scheme, the purpose is to reduce the probability of fiber filaments stacking when the fiber bundle moves from the reel 100 to the mounting member 3; this scheme guides the movement of the fiber bundle through the shielding ring 11 to avoid large-scale movement of the fiber bundle and reduce the probability of fiber filaments stacking; the maximum outer diameter of the shielding ring 11 is slightly smaller than the outer diameter of the reel 100, so that the fiber filaments directly pass over the connection between the reel 100 and the shielding ring 11 when moving, reducing the probability of the fiber filaments being stuck between the reel 100 and the shielding ring 11; in the vertical direction, there is an overlapping part between the shielding ring 11 and the first support roller 6, which is used to guide the fiber filaments to the first support roller 6 to prevent the fiber filaments from being stuck in the gap between the first support roller 6 and the shielding ring 11; the maximum outer diameter of the shielding ring 11 is larger than the outer diameter of the tensioning shaft 5 and the inner diameter of the reel 100, and is used to assist in positioning the reel 100.

[0024] Please refer to Figure 5 and Figure 6 The mounting member 3 is fixedly connected with a guide member 12 , and a guide slope 121 is provided on the guide member 12 near the first L-shaped member 7 .

[0025] In the above scheme, the guide member 12 is used to guide the fiber bundle on the mounting member 3 to the surface of the reel 100, so as to prevent the fiber bundle from slipping on the side of the reel 100 and failing to be wound onto the reel 100. After the fiber bundle is fixed by the first supporting roller 6 and the first L-shaped member 7, as the mounting member 3 rotates clockwise (hereinafter referred to as the attachment), the fiber bundle is prevented from slipping on the side of the reel 100 and failing to be wound onto the reel 100. Figure 1 The installation member 3 drives the guide member 12 to rotate circumferentially, so that the fiber bundle gradually moves onto the guide member 12. As the guide assembly controls the position of the fiber bundle, the fiber bundle is finally moved to the surface of the drum 100, thereby assisting the fiber bundle to be wound onto the surface of the drum 100.

[0026] Please refer to Figure 2-Figure 6 , Figure 8 and Fig. 9 The power assembly includes: a friction member 13, which is fixedly connected to the transmission shaft 4 and contacts with the mounting member 3, and the extrusion member 8 is frictionally matched with the friction member 13; a limit member 14, which is slidingly connected to the extrusion member 8 in a limited manner, and the limit member 14 is extrusion-matched with the extrusion member 8, and the limit member 14 is frictionally matched with the transmission shaft 4; an electric push rod 15, which is fixedly connected to the rotating disk 2, and the telescopic end of the electric push rod 15 is fixedly connected with a connecting member 16, and the connecting member 16 is extrusion-matched with the limit member 14; a sliding column 17, which is fixedly connected to the rotating disk 2, and a limited position portion 171 is provided on the sliding column 17, and the sliding column 17 is slidingly connected with a motor 18, and the output shaft of the motor 18 is fixedly connected to the transmission shaft 4; in the direction of the central axis of the mounting member 3, the distance between the limit member 171 and the motor 18 is equal to the distance between the limit member 14 and the extrusion member 8; a friction ring 19 is fixedly connected to the mounting member 3, and the friction ring 19 is frictionally matched with the rotating disk 2.

[0027] In the above scheme, it is intended to provide power for the movement of the transmission shaft 4 and the extrusion member 8; when switching the reel 100, after the first reel 100 is wound, the guide assembly drives the fiber bundle to move to the side of the reel 100, until the fiber bundle moves to the side of the reel 100, and the second winding roller can fix the fiber bundle, but at this time the fiber bundle is located on the side of the reel 100, that is, the fiber bundle is not wound on the first reel 100 in the above process. After the reel 100 is switched, the worker still needs to wind the fiber bundle on the first reel 100, which increases the workload of the worker. Large; the rear side of the friction member 13 and the front side of the middle part of the extrusion member 8 can be set as annular inclined surfaces to increase the contact area between the extrusion member 8 and the friction member 13, and increase the friction between the two; a roller can be set at the position where the limit member 14 contacts the transmission shaft 4, and the rotation axis of the roller is parallel to the rotation axis of the transmission shaft 4 to reduce the friction between the transmission shaft 4 and the limit member 14 during the rotation of the transmission shaft 4, while ensuring the friction between the limit member 14 and the transmission shaft 4 in the axial direction of the transmission shaft 4, and the friction between the limit member 14 and the transmission shaft 4 is greater than the friction between the friction ring 19 and the rotating disk 2.

[0028] The specific working principle of the above scheme is as follows: when it is necessary to switch the reel 100, the rotating disk 2 rotates, so that the reel 100 that has been wound up moves in a direction away from the guide assembly, and the new reel 100 moves in a direction close to the guide assembly (see the attached Figure 1 The fiber bundle is laid on the new reel 100, and the motor 18 corresponding to the new reel 100 is started to match the linear speed of the new reel 100 with the speed of the fiber bundle movement. Subsequently, the guiding assembly controls the fiber bundle to move backward to move the fiber bundle to the rear edge of the two reels 100. At this time, the electric push rod 15 is started (unless otherwise specified, the parts corresponding to the new reel 100 are assumed to be started). The telescopic end of the electric push rod 15 drives the limiting member 14 forward through the connecting member 16. The limiting member 14 drives the transmission shaft 4 forward through friction. The transmission shaft 4 drives the tensioning shaft 5 and the new reel 100 forward. The transmission shaft 4 drives the mounting member 3, the first support roller 6, the first L-shaped member 7 and the extrusion member 8 forward together through the friction member 13, so that the fiber bundle moves along the shielding ring 11 to the surface of the first support roller 6, and drives the first support roller 6 to rotate.

[0029] After the fiber bundle moves to the surface of the first supporting roller 6, as the limiting member 14 continues to move forward, the rear side surface inside the limiting member 14 fits with the rear side surface of the extruding member 8 (at this time, the motor 18 contacts the limiting portion 171 and stops moving, that is, the transmission shaft 4 stops moving; at the same time, the friction ring 19 loses contact with the rotating disk 2), and then the limiting member 14 slides forward relative to the transmission shaft 4 and pushes the extruding member 8 forward, and the extruding member 8 drives the first L-shaped member 7 to contact with the first supporting roller 6 to complete the fixation of the fiber bundle. At this time, the extruding member 8 contacts the friction member 13, and the extruding member 8 is driven by the friction member 13 to transmit The movable mounting part 3 rotates together, and then the blade on the winding machine is used to cut the fiber bundle between the two reels 100. With the rotation of the mounting part 3 and the adjustment of the fiber bundle by the guide component, the fiber bundle is wound onto the new reel 100. After the fiber bundle is reciprocated and wound on the new reel 100 for two layers, the end of the fiber bundle is fixed by mutual extrusion between the fiber bundles on the reel 100, and then the telescopic end of the electric push rod 15 is controlled to extend and reset, so that the limit member 14, the extrusion member 8 and the mounting part 3 are all reset, and then the fiber bundle is controlled to be evenly wound on the surface of the new reel 100 under the action of the guide component.

[0030] Please refer to Figure 4 , Figure 6 , Fig. 9 and Fig.10 , and also includes: two slitting components, respectively arranged on adjacent mounting parts 3, the slitting components are used to cut fibers, and the slitting components include: a connecting rod 20, fixed to the extrusion member 8 and slidably connected to the mounting member 3; a mounting block 21, slidably connected in the mounting member 3, the mounting block 21 is provided with an inclined slide groove 211, the connecting rod 20 slides in the inclined slide groove 211, and an electric heating rod 22 is installed on the side of the mounting block 21 away from the central axis of the mounting member 3.

[0031] The above scheme aims to solve the problem that when the existing reel 100 is switched, the fiber bundle is cut off between the two reels 100, so that the distance between the fixing point of the fiber bundle of the new reel 100 and the end of the fiber bundle is long (hereinafter, this section of the fiber bundle is referred to as the free fiber bundle). As the new reel 100 rotates, the free fiber bundle is irregularly wound around the side of the reel 100, so that bulges are likely to appear on the side of the reel 100, and knots are likely to appear between the fiber filaments during subsequent unwinding, affecting the quality of the finished product; the connecting rod 20 and the guide 12 are respectively located on both sides of the first support roller 6; a small storage battery can be installed in the mounting block 21 to power the electric heating rod 22 and control the opening and closing of the electric heating rod 22 through an external remote control signal.

[0032] During the forward movement of the extrusion member 8 relative to the mounting member 3, the extrusion member 8 drives the connecting rod 20 to move, so that the connecting rod 20 slides along the inclined slide groove 211 and pushes the mounting block 21 and the electric heating rod 22 to move. At the same time, the first L-shaped member 7 moves and approaches the first support roller 6. When the first support roller 6 and the first L-shaped member 7 complete the fixation of the fiber bundle, the electric heating rod 22 protrudes out of the mounting member 3 and contacts the fiber bundle attached to the surface of the mounting member 3. At this time, the electric heating rod 22 is controlled to start and melt the fiber bundle, thereby reducing the length of the free fiber bundle.

[0033] Please refer to Figure 4 , Figure 6 , Fig. 9 and Fig.10 , and also includes: two extrusion assemblies, respectively arranged on adjacent mounting members 3, the extrusion assemblies are used to press the fibers, and the extrusion assemblies include: a second L-shaped member 23, slidably connected to the mounting member 3, the second L-shaped member 23 is rotatably connected to an extrusion roller 24, the second L-shaped member 23 and the extrusion member 8 are jointly fixed with a second elastic sheet 25; a second supporting roller 26, rotatably connected to the mounting member 3 near the extrusion roller 24, the second supporting roller 26 is extrusion-matched with the extrusion roller 24.

[0034] The above scheme aims to solve the problem that when cutting the fiber bundle, due to the tension of the fiber bundle itself, as the fiber filaments are cut one by one, the fiber filaments in the last broken part are prone to breakage, and the breaking position is uncertain, which affects the flatness of the fiber bundle cut and the quality of the finished product; the second support roller 26 is made of the same material as the first support roller 6, the squeezing roller 24 is made of high-temperature resistant rubber material, and the surface of the squeezing roller 24 is provided with a modified polyurethane coating, which is used to reduce the surface adhesion of the squeezing roller 24 and prevent the melted fiber filaments from adhering to the surface of the squeezing roller 24. The squeezing roller 24 and the second support roller 26, the first L-shaped member 7 and the first support roller 6 are respectively clamped at two positions of the fiber bundle to avoid the fiber filaments from breaking when they are melted due to the tension of the fiber bundle itself, thereby ensuring the quality of the finished product.

[0035] While the distance between the first L-shaped member 7 and the first support roller 6 is reduced, the distance between the squeezing roller 24 and the second support roller 26 is simultaneously reduced, until the first L-shaped member 7 and the first support roller 6 cooperate to complete the clamping of the fiber filaments, and the squeezing roller 24 and the second support roller 26 also clamp the fiber filaments therebetween, and then the electric heating rod 22 melts the fiber filaments between the first support roller 6 and the second support roller 26, and as the mounting member 3 rotates, the wound reel 100 pulls the fiber filament end portion gradually out of between the squeezing roller 24 and the second support roller 26, during this process, the fiber filament drives the squeezing roller 24 and the second support roller 26 to rotate, and the squeezing roller 24 and the second support roller 26 squeeze the position where the fiber filament end portion is melted, so that all the fiber filaments of the fiber bundle are fixed together, to prevent the fiber filament end portion from loosening, and to reduce the work intensity of subsequent workers when arranging the fiber bundle.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
