Description

Technical Field

[0001] This utility model belongs to the field of fiber winding machine technology, and in particular relates to an automatic fiber cutting and roller changing device for a carbon fiber 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 wire cutting and roller changing device for a carbon fiber take-up machine. After the rollers are switched, the carbon fiber is guided and inserted into the gap of the wire clamping assembly, and then the carbon fiber is cut. Since the wire clamping assembly is a rigid connection structure, when the carbon fiber is subsequently rolled up, the wire clamping assembly is prone to clamping the carbon fiber and making it difficult to remove, resulting in the carbon fiber being pulled off and accumulating inside the wire clamping assembly. Furthermore, when the rollers are pushed out, the wire clamping assembly will pull out the end of the carbon fiber, causing the filament roll to loosen.

[0004] Therefore, it is necessary to improve the existing automatic wire cutting and roller changing device for wire take-up machines. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide an automatic filament cutting and roller changing device for a carbon fiber winding machine, which reduces the chance of carbon filament getting stuck and improves the ease of use of the roller changing device.

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

[0007] An automatic filament cutting and roller changing device for a carbon fiber take-up machine includes a base plate, on which a turntable and an ejector plate are provided. Two take-up rollers are rotatably mounted on the turntable. A wire clamping seat is fixedly connected to the end of each take-up roller. The axial direction of the take-up roller is a first direction. A clamping claw is slidably connected to the wire clamping seat along the first direction. A wire clamping gap is provided between the clamping claw and the wire clamping seat to allow carbon fiber to enter. A first spring is provided between the clamping claw and the wire clamping seat.

[0008] Preferably, the clamping seat has a guide hole extending in a first direction, and the gripper is fixedly connected to a slide rod that slides coaxially with the guide hole. The first spring is disposed between the slide rod and the clamping seat.

[0009] Preferably, a limiting groove is formed on the side of the clamping seat near the gripper, and a limiting block is fixedly connected to the end of the gripper, with the limiting block slidingly engaging with the limiting groove.

[0010] Preferably, the front end of the gripper is chamfered on the side adjacent to the card holder.

[0011] Preferably, the ejector plate is slidably disposed on the base plate along the first direction, and an auxiliary ejector plate is connected to the ejector plate. The auxiliary ejector plate is configured to push the gripper to move away from the wire holder.

[0012] Preferably, a guide sleeve with its axis extending along a first direction is fixedly connected to the base plate, a guide rod is slidably fitted coaxially on the inner side of the guide sleeve, the push plate is fixedly connected to the guide rod, and a power component that is drivenly connected to the push plate is also provided on the base plate.

[0013] Preferably, the auxiliary push plate is slidably disposed on the guide rod, and a second spring is provided between the auxiliary push plate and the push plate.

[0022] 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.

[0023] The terms "top surface," "bottom surface," and "full surface" refer to the normal operating state of the shredding and roller changing device. They are used only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model.

[0024] like Figure 1-3 As shown, an automatic filament cutting and roller changing device for a carbon fiber take-up machine includes a base plate 1, a turntable 3 and an ejector plate 2 on the base plate 1, two take-up rollers 4 rotatably mounted on the turntable 3, and a wire clamping seat 402 fixedly connected to the end of the take-up roller 4. The axial direction of the take-up roller 4 is the first direction, and a clamp 401 is slidably connected to the wire clamping seat 402 along the first direction. There is a wire clamping gap between the clamp 401 and the wire clamping seat 402 for carbon fiber to enter, and a first spring 407 is provided between the clamp 401 and the wire clamping seat 402.

[0025] The aforementioned automatic filament cutting and roller changing device is applicable to, but not limited to, the winding of carbon fiber bundles. Its working principle is as follows: the winding roller 4 is a tension roller with a roll sleeved on it. The winding roller 4 is driven to rotate by its own motor, thereby winding the carbon fiber bundle onto the roll, completing the winding of the carbon fiber. After the processing is completed, the turntable 3 is driven to rotate by the motor to switch the positions of the two winding rollers 4. Then, the carbon fiber is clamped and fixed by the gripper 401 and the wire holder 402 at the end of the empty winding roller 4, and the carbon fiber is cut by the blade, thereby winding the carbon fiber onto the roll above the winding roller 4. The wound roll is pushed off the winding roller 4 by the push plate 2, thereby completing the automatic filament cutting and roller changing operation of the winding machine, thus realizing the continuous winding of carbon fiber and improving the production efficiency of the winding machine.

[0026] Compared with the existing wire-clamping assembly of the take-up machine, this take-up machine uses a combination of jaws 401 and wire clamping seat 402 to clamp carbon fiber as a bundle. The elastic force of the first spring 407 is used to push the jaws 401 and wire clamping seat 402 closer together, thereby generating a certain clamping force between them. By selecting first springs 407 with different elastic coefficients, the magnitude of the clamping force between the jaws 401 and wire clamping seat 402 can be effectively controlled, so that when the carbon fiber is clamped between the jaws 401 and wire clamping seat 402, the clamping and fixing of the carbon fiber can be effectively achieved. At the same time, when the push plate 2 pushes the drum to separate from the take-up roller 4, the jaws 401 can automatically open under the pulling force of the carbon fiber, thereby facilitating the release of the carbon fiber from between the jaws 401 and wire clamping seat 402, improving the convenience of drum unloading, and thus improving the working efficiency and ease of use of the automatic wire cutting and roller changing device.

[0027] Further improvements include, for example Figure 3 As shown, the cable holder 402 has a guide hole 409 extending in the first direction, and a slide rod 404 that is coaxially and slidably connected to the gripper 401 is fixedly connected to the gripper 401. A first spring 407 is disposed between the slide rod 404 and the cable holder 402.

[0028] In this automatic filament cutting and roller changing device, the guide hole 409 and the slide rod 404 cooperate with each other to guide and support the movement of the gripper 401, improve the stability of the gripper 401, and thus improve the firmness of the carbon fiber clamping. The slide rod 404 is set through the guide hole 409, and the first spring 407 is sleeved on the slide rod 404. Its two ends are respectively connected to one end of the slide rod 404 that passes through the guide hole 409 and the wire clamping seat 402. The first spring 407 is in a compressed state so that its elastic force can keep the gripper 401 and the wire clamping seat 402 in a clamping state.

[0029] Further improvements include, for example Figure 3 As shown, a limiting groove 406 is provided on the side of the card seat 402 near the gripper 401, and a limiting block 405 is fixedly connected to the end of the gripper 401. The limiting block 405 and the limiting groove 406 are in sliding engagement.

[0030] In the above device, the limiting groove 406 and the limiting block 405 limit each other, further improving the stability of the gripper 401. Furthermore, during processing, by changing the opening position and size of the limiting groove 406, the depth of the wire-holding gap can be effectively controlled, allowing the carbon fiber bundle to be completely accommodated in the wire-holding gap.

[0031] Further improvements include, for example Figure 3As shown, a chamfer 408 is provided on the front end of the gripper 401 near the wire clamping seat 402. The chamfer 408 allows the wire clamping gap to form a V-shaped opening, which can guide the carbon fiber bundle into the wire clamping gap, making it easier for the gripper 401 and the wire clamping seat 402 to accurately clamp the carbon fiber bundle, thereby reducing the failure rate of the equipment.

[0032] Further improvements include, for example Figure 1 and 4 As shown, the ejector plate 2 is slidably disposed on the base plate 1 along the first direction. A secondary pusher plate 202 is connected to the ejector plate 2. The secondary pusher plate 202 is configured to push the gripper 401 to move away from the cable holder 402.

[0033] As the equipment is used for a longer period of time, the dirt adhering to the slide bar 404 will increase its sliding resistance, resulting in increased resistance to opening the gripper 401. Therefore, an auxiliary push plate 202 is set up. The auxiliary push plate 202 and the push plate 2 are powered by the same power source and move back and forth along the first direction. The auxiliary push plate 202 can push the gripper 401 away from the wire holder 402, thereby actively opening the gripper 401, which facilitates the separation of carbon fiber from the gripper 401 and the wire holder 402, further reducing the probability of carbon fiber jamming and reducing the failure rate of the automatic wire cutting and roller changing device.

[0034] Further improvements include, for example Figure 4 As shown, a guide sleeve 203 with its axis extending along a first direction is fixedly connected to the base plate 1. A guide rod 206 is slidably fitted on the inner side of the guide sleeve 203. The push plate is fixedly connected to the guide rod 206. A power component 201 that is connected to the push plate is also provided on the base plate 1.

[0035] Further improvements include, for example Figure 2 and 5 As shown, the auxiliary push plate 202 is fixedly connected to the sliding sleeve 205, the sliding sleeve 205 is slidably engaged with the guide rod 206, and a second spring 204 is provided between the auxiliary push plate 202 and the push plate 2; the end of the take-up roller 4 is slidably engaged with the sliding ring 403, the sliding ring 403 is located on the side of the wire holder 402 away from the clamp 401, the sliding ring 403 is detachably connected with the sliding rod 404, along the first direction, the push plate 2 and the sliding ring 403 are spaced apart, and the auxiliary push plate 202 and the sliding ring 403 have overlapping parts.

[0036] Specifically, the elastic force generated by the second spring 204 is greater than that generated by the first spring 407. The power component 201 is a cylinder. When the spool fully wound with carbon fiber is pushed out, the power component 201 pushes the push plate 2 away from the base plate 1. Since the outer diameter of the spool increases after being fully wound with carbon fiber, the push plate 2 can abut against the spool and apply a pushing force to the spool, causing it to partially detach from the take-up roller 4. At the same time, under the tension of the second spring 204, the auxiliary push plate 202 moves together with the push plate 2, so that the auxiliary push plate 202 can abut against the sliding ring 403 and push the sliding ring 403. The sliding ring 403 is designed so that when the take-up roller 4 stops at different positions, the auxiliary push plate 202 can abut against the sliding ring 403 and apply a pushing force to it, pushing the sliding ring 403. The device moves away from the base plate 1, which in turn pushes the gripper 401 to open, allowing the carbon fiber to disengage. When the sliding ring 403 finishes its stroke, the second spring 204 is stretched, and the push plate 2 continues to move, pushing the drum out of the take-up roller 4. At this time, the gripper 401 remains open. While pushing out the drum, the carbon fiber bundle automatically disengages from the gripper 401 and the fiber holder 402. Then, the power component 201 drives the push plate 2 to reset. Under the action of the first spring 407 and the second spring 204, both the gripper 401 and the auxiliary push plate 202 are reset, thus completing the entire drum pushing process. During this process, the gripper 401 is automatically opened, reducing the probability of carbon fiber jamming, improving the working efficiency of the automatic fiber cutting and roller changing device, and reducing the failure rate.
