Description

Technical Field

[0001] This utility model belongs to the field of fiber winding machine technology, and in particular relates to an automatic roller changing assembly for a carbon fiber tow winding machine. Background Technology

[0002] A winding machine is a device used to collect and wind materials such as yarn and fiber. It is widely used in many industries such as textiles, plastics, wires and cables, and optical fibers.

[0003] Patent CN221821538U discloses an automatic filament cutting and roller changing device for a carbon filament take-up machine. After the filament cutting and roller changing device switches the rollers, it needs to cut the filament bundle so that the cut filament bundle can continue to be wound on the empty take-up roller. However, after the filament bundle is cut, there is no effective fixing measure for the end of the carbon filament that has been wound up. As a result, the end of the carbon filament may loosen due to its own elasticity or slight external force, causing the outer layer of carbon filament to fall off the roller surface and destroying the overall neatness of the winding.

[0004] Therefore, it is necessary to improve the automatic roller changing assembly in the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide an automatic roller changing component for a carbon fiber tow winding machine, which improves the winding effect of the winding machine on carbon fiber tow.

[0006] To achieve the above objectives, the specific technical solution of the automatic roller changing assembly for the carbon fiber tow take-up machine of this utility model is as follows:

[0007] An automatic roller changing assembly for a carbon fiber tow take-up machine includes a machine body, on which a turntable and an ejector plate are mounted. The turntable is equipped with a take-up roller, a filament cutter, and a pressure rod. The end of the pressure rod is fixedly connected to the turntable, and a positioning part is fixedly connected to the end of the pressure rod. A clamping part is also slidably connected to the pressure rod, and a suction assembly is provided between the positioning part and the clamping part.

[0008] Preferably, in order to improve the stability of the connection between the clamping part and the positioning part and the pressure rod, both the clamping part and the positioning part are cylindrical structures and are sleeved on the outer periphery of the pressure rod.

[0009] Preferably, in order to prevent the clamping part and the positioning part from rotating around the pressure rod and to further improve the stability of the connection between the two and the pressure rod, a positioning groove extending parallel to its own axis is provided on the side of the pressure rod, and a positioning block is provided on the inner wall of both the clamping part and the positioning part, and the positioning block slides in cooperation with the positioning groove.

[0011] Preferably, in order to facilitate fixing the positioning part to the pressure rod, the positioning part has a threaded hole along its own radial direction, and a locking screw is threaded into the threaded hole.

[0012] Preferably, in order to facilitate the adjustment of the position of the clamping part on the pressure rod, the two pressure rods are symmetrically arranged about the axis of the turntable, and the minimum distance between the pressure rod and the axis of the turntable gradually decreases from the end to the front end of the pressure rod.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0024] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the automatic roller changing assembly and are only for the purpose of facilitating the description of this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] like Figure 1 and 2 As shown, an automatic roller changing assembly for a carbon fiber tow take-up machine includes a machine body 1, a turntable 2 and an ejector plate 6 on the machine body 1, a take-up roller 3, a filament cutter 4 and a wire pressing rod 5 on the turntable 2, the end of the wire pressing rod 5 is fixedly connected to the turntable 2, a positioning part 8 is fixedly connected to the end of the wire pressing rod 5, a clamping part 7 is slidably connected to the wire pressing rod 5, and a suction component is provided between the positioning part 8 and the clamping part 7.

[0026] The aforementioned winding machine is applicable to, but not limited to, the winding of carbon fiber tows. The automatic roller changing assembly enables switching between two winding rollers 3 to achieve continuous winding of the tow. The switching steps for the winding rollers 3 are as follows: when one winding roller 3 is fully wound, the turntable 2 rotates to switch the positions of the two winding rollers 3. At this time, the tow spanning between the two winding rollers 3 is supported by the pressure rod 5. Then, the suction assembly causes the positioning part 8 and the clamping part 7 to adhere to each other, thereby clamping the tow spanning between the two winding rollers 3. Finally, the filament is cut by the filament cutter 4. One end of the filament bundle is clamped and fixed by the wire clamping assembly on the empty take-up roller 3, allowing the filament bundle to continue winding on the empty take-up roller 3. The end of the filament bundle on the take-up roller 3 after winding is clamped and fixed by the positioning part 8 and the clamping part 7, thereby preventing the filament bundle after winding from loosening, and thus preventing the outer layer of filament bundle from falling off the roller surface, improving the quality of the carbon fiber filament bundle wound by the take-up machine. When it is necessary to remove the filament bundle after winding, the operator needs to manually remove the filament bundle from between the positioning part 8 and the clamping part 7, tightly wrap the end of the filament bundle around the wound filament bundle, and finally fix the end of the filament bundle.

[0027] Further improvements include, for example Figure 2 As shown, both the clamping part 7 and the positioning part 8 are cylindrical structures and are sleeved on the outer periphery of the pressure rod 5. The outer surface of the pressure rod 5 is covered with a lubricating layer.

[0028] Specifically, in this winding machine, the lubricating layer is a polytetrafluoroethylene (PTFE) layer. PTFE has excellent lubrication properties, which can reduce the friction between the clamping part 7 and the pressure rod 5, thereby making the sliding of the clamping part 7 smoother and facilitating the adjustment of the position of the clamping part 7. It can also reduce the friction between the yarn bundle and the pressure rod 5, thereby reducing wear on the yarn bundle. The cylindrical clamping part 7 and the positioning part 8 can form an annular wrap around the pressure rod 5, and can form radial limits between each other, thereby improving the stability of the connection between the clamping part 7 and the positioning part 8 and the pressure rod 5, and further improving the firmness of the clamping part 7 and the positioning part 8 in clamping the end of the yarn bundle.

[0029] Further improvements include, for example Figure 3-5 As shown, the side of the pressure rod 5 has a positioning groove 501 extending parallel to its own axis. Positioning blocks 703 are provided on the inner walls of both the clamping part 7 and the positioning part 8. The positioning blocks 703 slide in conjunction with the positioning groove 501. One end of the positioning groove 501, adjacent to the end of the pressure rod 5, is connected to the outside. The positioning blocks 703 and the positioning groove 501 cooperate to limit movement, preventing them from rotating around the axis of the pressure rod 5. This prevents movement after the positioning blocks 703 and the positioning groove 501 have clamped the wire bundle, thus improving the firmness of the clamping. The connection of one end of the positioning groove 501 to the outside allows for easy removal of the positioning blocks 703 and the positioning groove 501 from the pressure rod 5, improving the convenience of equipment maintenance.

[0030] Further improvements include, for example Figure 5 As shown, the positioning part 8 has a threaded hole 803 along its radial direction, and a locking screw 804 is threaded into the threaded hole 803. The front end of the locking screw 804 abuts against the pressure rod 5, thereby fixing the positioning part 8 onto the pressure rod 5 under the action of friction between the two, preventing the positioning part 8 from sliding along the axial direction of the pressure rod 5.

[0031] Further improvements include, for example Figure 1As shown, the two pressure rods 5 are symmetrically arranged about the axis of the turntable 2. The minimum distance between the pressure rod 5 and the axis of the turntable 2 gradually decreases from the end to the front end of the pressure rod 5. The arrangement of the pressure rods 5 in the above-mentioned winding machine allows the yarn bundle to fall between the clamping part 7 and the positioning part 8 when it contacts the pressure rod 5. As the turntable 2 rotates, the clamping part 7 slides along the pressure rod 5 under its own weight, thus opening and closing the clamping part 7. Specifically, the working principle is as follows: first, the pressure rod 5 is at the top of the turntable 2. At this time, the front end of the pressure rod 5 is lower than the rear end. The clamping part 7 slides towards the front end of the pressure rod 5 under its own weight, increasing the distance between the clamping part 7 and the positioning part 8. When the winding roller 3 in the winding position finishes winding, it rotates 180 degrees counterclockwise to reach the unloading position. During the process, the pressure rod 5 rotates from the top to the bottom of the turntable. As the pressure rod 5 moves, it contacts the wire bundle and provides support for it. As the pressure rod 5 rotates, the horizontal height of the front end of the pressure rod 5 relative to the end gradually increases. When it rotates to the bottom position of the turntable 2, the horizontal height of the front end of the pressure rod 5 is greater than that of the end. At this time, the clamping part 7 moves closer to the positioning part 8 under its own gravity, reducing the distance between them. Thus, under the action of the suction component, the clamping part 7 and the positioning part 8 attract each other, achieving the clamping and fixing effect on the wire bundle. When the suction component is not working, the wire bundle can push the clamping part 7 to slide along the pressure rod 5.

[0032] Further improvements include, for example Figure 4 and 5 As shown, the suction component includes an electromagnet 801 and a permanent magnet 701. The electromagnet 801 is fixedly connected to the positioning part 8, and the permanent magnet 701 is fixedly connected to the clamping part 7. When the clamping part 7 approaches the positioning part 8, the electromagnet 701 is energized and attracts the permanent magnet 801, thereby causing the positioning part 8 and the clamping part 7 to attract each other, so as to achieve the clamping and fixing effect on the wire bundle. The positioning part 8 is located on the side of the clamping part 7 near the turntable 2. Since the electromagnet 801 needs to be equipped with wires, it is placed on the stationary positioning part 8 to facilitate the arrangement of wires.

[0033] Further improvements include, for example Figure 4 and 5 As shown, the clamping part 7 has an anti-slip protrusion 702 on its side adjacent to the positioning part 8, and the positioning part 8 has an anti-slip groove 802 on its side adjacent to the clamping part 7. The anti-slip protrusion 702 and the anti-slip groove 802 match each other. The anti-slip protrusion 702 is a rubber strip. The provision of the anti-slip protrusion 702 and the anti-slip groove 802 can increase the coefficient of friction between the positioning part 8 and the clamping part 7, increase the friction between the two when clamping the filament bundle, and thus improve the firmness of clamping the filament bundle.
