Description
Technical Field
[0001] The utility model relates to the technical field of carbon fiber production equipment, and more specifically to a rotary active wire clamping mechanism for a carbon wire collecting machine. Background Art
[0002] Carbon fiber is a new type of high-strength, high-modulus fiber material with a carbon content of more than 95%. It is made of organic fibers such as flaky graphite microcrystals stacked along the axial direction of the fiber. It is a microcrystalline graphite material obtained by carbonization and graphitization. Carbon fiber is "soft on the outside and hard on the inside" and is lighter than metallic aluminum.
[0003] After the carbon filament winder actually winds up, when the carbon filament winder drum has completed winding, it is necessary to replace it with a new winding drum for new winding. However, in the prior art, after the carbon filament winder has completed winding, it is necessary to first stop the winder, manually cut the carbon filament, and then replace it with a new drum, and manually wind a few turns of carbon filament or manually put the carbon filament into the card slot. The operation is cumbersome and the degree of automation is low. In addition, the existing wire clamping structure clamps the carbon filament in a passive manner. When the carbon filament is rolled up on the winding drum, the wire clamping structure can easily clamp the carbon filament and make it difficult to remove it. When the drum is removed, the wire clamping structure may pull the carbon filament out, causing the filament roll to loosen. Therefore, a technical solution is needed to solve the above problems. Utility Model Content
[0004] The utility model aims to overcome the above-mentioned deficiencies of the prior art and to provide a rotary active wire clamping mechanism for a carbon wire take-up machine in order to be able to clamp the carbon wire and facilitate its removal.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] The utility model discloses a rotary active wire-clamping mechanism for a carbon filament collecting machine, comprising an inflatable shaft, a sleeve, a kit, a cylinder, and a turntable.

[0007] Furthermore, the turntable is provided with a sleeve, the rotating shaft passes through the sleeve, the rotating shaft is installed concentrically with the sleeve, and the rotating shaft is installed on the sleeve through a second bearing.
[0008] Furthermore, a third bearing is installed at one end of the rotating shaft away from the shaft roller, and the third bearing is connected to the sleeve.
[0009] Furthermore, the cylinder and the kit are respectively located on both sides of the turntable, the kit is installed with a connecting rod, the connecting rod passes through the turntable, and the connecting rod is connected to the cylinder.
[0010] Furthermore, the kit is installed with a guide rod, and the guide rod passes through the turntable.

[0014] The beneficial effects of the utility model are:
[0015] 1. The utility model installs a sleeve that can rotate with the shaft rod on the shaft rod. The sleeve is driven by a cylinder to move along the shaft rod to form a wire-holding space that can clamp the carbon filament between the sleeve and the shaft roller, so that the sleeve actively holds the carbon filament. The electrical control system can accurately complete the wire holding before winding, preventing the carbon filament from being stuck by the wire holding structure.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the present embodiment discloses a rotary active wire-clamping mechanism for a carbon filament winding machine, comprising an inflatable shaft 1, a sleeve 2, a kit 3, a cylinder 4, and a turntable 5. There are two inflatable shafts 1, and the two inflatable shafts 1 are symmetrically arranged around the center of the turntable 5. The turntable 5 is rotatably mounted on a mounting plate 10. The turntable 5 rotates and stays at two positions (a winding position and a winding position). When the utility model is actually used, the inflatable shaft 1 in the winding position corresponds to a wire drawing transmission mechanism 8 and a wire arranging mechanism 9. Both the wire drawing transmission mechanism 8 and the wire arranging mechanism 9 are mounted on the mounting plate 10. The wire arranging mechanism 9 is used to arrange and wind the carbon filaments on a reel. The wire drawing transmission mechanism 8 can pull the carbon filaments into the wire-clamping space 7 before winding the carbon filaments, and pull the carbon filaments to touch the wire cutting knife to cut the carbon filaments.
[0025] like Figure 1 , Figure 2 As shown, the inflatable shaft 1 includes a shaft roller 11 and a rotating shaft 12, the turntable 5 is provided with a sleeve 51, the rotating shaft 12 passes through the sleeve 51, the rotating shaft 12 and the sleeve 51 are installed concentrically, the rotating shaft 12 is installed on the sleeve 51 through the second bearing 6, the rotating shaft 12 passes through the turntable 5 and is rotatably connected to the turntable 5, the inflatable shaft 1 is used to set the wire collection reel, the inflatable shaft 1 needs to rotate for wire collection, and the inflatable shaft 1 is connected to the turntable 5 through the second bearing 6 and can realize self-rotation on the turntable 5.
[0026] More preferably, a third bearing 52 is installed at the end of the rotating shaft 12 away from the shaft roller 11, and the third bearing 52 is connected to the sleeve 51, so that the connection between the rotating shaft 12 and the turntable 5 is more stable, and the end of the rotating shaft 12 where the shaft roller 11 is not installed is connected through the third bearing 52, so that the connection between the rotating shaft 12 and the sleeve 51 is more stable.
[0027] like Figure 1 , Figure 2 As shown, the sleeve 2 is located at one end of the shaft roller 11 close to the turntable 5, that is, the sleeve 2 is located between the shaft roller 11 and the turntable 5, the shaft roller 11 is fixedly mounted on the rotating shaft 12, and the sleeve 2 is mounted on the rotating shaft 12. The sleeve 2 can slide along the axial direction of the rotating shaft 12 and can rotate with the rotating shaft 12. The sleeve 2 is provided with a slider protruding toward the rotating shaft 12, and the rotating shaft 12 is provided with a slide groove corresponding to the slider, so that the sleeve 2 can move along the slide groove. At the same time, the slide groove limits the slider in the rotation direction of the rotating shaft 12, thereby driving the sleeve 2 to rotate together, and the sleeve 2 can move between the shaft roller 11 and the turntable 5.
[0028] like Figure 1 , Figure 2 , Figure 3 As shown, the kit 3 is rotatably connected to the sleeve 2, and the kit 3 is sleeved on the outer circumference of the sleeve 2. The kit 3 is connected to the sleeve 2 through a first bearing 31, so that the sleeve 2 can remain relatively non-rotating when the shaft 12 rotates. The cylinder 4 is fixedly installed on the turntable 5, and the cylinder 4 is connected to the kit 3. The cylinder 4 and the kit 3 are respectively located on both sides of the turntable 5. The kit 3 is installed with a connecting rod 32, and the connecting rod 32 passes through the turntable 5. The connecting rod 32 is connected to the cylinder 4, and the piston 41 of the cylinder 4 is connected to the connecting rod 32. The cylinder 4 can drive the connecting rod 32 to move and then drive the kit 3 to move. Since the kit 3 is connected to the sleeve 2 through the first bearing 31, the movement of the kit 3 can drive the sleeve 2 to move along the shaft 12, so that the sleeve 2 can approach or move away from the shaft roller 11, and when the sleeve 2 is away from the shaft roller 11, a wire-stuck space 7 is formed between the two.
[0029] More preferably, the kit 3 is installed with a guide rod 33, which passes through the turntable 5. The guide rod 33 and the connecting rod 32 both pass through the turntable 5. The guide rod 33 limits the rotation direction of the kit 3 and guides the movement of the kit 3. The kit 3 is unstable if it only relies on the connecting rod 32 to provide guidance and limitation. The force on the connecting rod 32 will cause friction between the connecting rod 32 and the turntable 5, affecting the sliding. The provision of the guide rod 33 can distribute the force for the connecting rod 32. The guide rod 33 and the connecting rod 32 are symmetrically arranged, and the structure is more stable.
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, the spring 23 is installed on the rotating shaft 12, and the rotating shaft 12 is provided with a retaining ring 121. The two ends of the spring 23 respectively resist the retaining ring 121 and the shaft sleeve 2, and the retaining ring 121 is located between the shaft sleeve 2 and the second bearing 6. One side of the retaining ring 121 limits the second bearing 6, and the other side of the retaining ring 121 is used to limit the spring 23. The spring 23 ring sleeve is installed on the rotating shaft 12, and the spring 23 resists the shaft sleeve 2 toward the shaft roller 11. After the cylinder 4 releases the kit 3, the spring 23 pushes the shaft sleeve 2 so that the shaft sleeve 2 is close to the shaft roller 11, and the wire-stuck space 7 is reduced so that the shaft sleeve 2 and the shaft roller 11 are aligned with the wire-stuck space. 7 is clamped. When the present embodiment is working, when the winding of the filament drum is completed, the cylinder 4 is started to drive the sleeve 2 away from the shaft roller 11 to form a wire-stuck space 7. The wire drawing transmission mechanism 8 pulls the carbon filament into the wire-stuck space 7. After the cylinder 4 is closed, the spring 23 presses the sleeve 2 to restore the position, clamping the carbon filament between the sleeve 2 and the shaft roller 11. The wire drawing transmission mechanism 8 will continue to pull the carbon filament to touch the wire cutting knife to break the wire. When the turntable 5 rotates to make the inflatable shaft 1 rotate to the winding position, the cylinder 4 is started to release the clamped carbon filament to complete the winding, which can prevent the carbon filament from being stuck by the wire-stuck mechanism and causing the wire roll to be pulled loose.
[0031] like Figure 1 , Figure 2 As shown, the sleeve 2 is provided with a clamping plate 22, and a wire-holding space 7 is formed between the clamping plate 22 and the shaft roller 11. The sleeve 2 is provided with an embedding block 21, and the shaft roller 11 is provided with an embedding groove 111 corresponding to the embedding block 21. The embedding block 21 is located on the radial inner side of the clamping plate 22. When the distance between the sleeve 2 and the shaft roller 11 is the farthest, the embedding block 21 is at least partially located in the embedding groove 111. The embedding block 21 can limit the carbon filament stuck in the wire-holding space 7 to prevent the carbon filament from being entangled on the rotating shaft 12, making it more convenient to remove the carbon filament.
[0032] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
