Description

Technical Field

[0001] The invention relates to the technical field of wire winding, and in particular to a conveying device for fibers. Background Art

[0002] Fiber refers to a substance composed of continuous or discontinuous filaments, which can be woven into fine threads, threads and hemp ropes, and can also be woven into fiber layers when making paper or felt. It is also often used to make other materials and to form composite materials with other materials. The existing automatic roll-changing technology clamps the fibers with a clamping device and then cuts the fibers with a cutter. The fibers can then be wound from one bobbin to another, and then the wound fiber roll is removed for easy transportation.

[0003] With reference to the Chinese patent document with the authorization announcement number CN117185043B, a carbon fiber roll changing mechanism and a roll changing method thereof are disclosed, including an installation panel, a turntable, two baffles, two wire winding mechanisms and a wire cutting mechanism; the wire winding mechanism includes a wire winding assembly and a wire clamping assembly sleeved on the wire winding assembly; the wire clamping assembly includes a first wire clamping plate, a telescopic movable assembly, a second wire clamping plate and a plurality of limiting mechanisms connected to the second wire clamping plate, the limiting mechanisms being used to limit the distance that the fiber moves toward the circular edge of the wire clamping assembly when it is under force and tightened.

[0004] With regard to the above-mentioned related technologies, the fibers need to be clamped first and then cut when being cut, which may easily cause the fibers to be entangled in the clamped part. When the fiber winding is completed, part of the wire bundle will be located outside the fiber roll, thereby reducing the winding quality of the fiber roll. Part of the fibers located outside the fiber roll will also cause the fiber roll to loosen under external force. At the same time, when the fibers are wound around the clamped part, it will also affect the removal of the fiber roll. Summary of the invention

[0005] In view of this, the present invention provides a conveying device for fibers, aiming to solve the problem in the prior art that part of the fibers are easily located outside the fiber roll after the yarn tube is replaced.

[0006] To solve the above technical problems, in a first aspect, the present invention provides a conveying device for fibers, comprising a mounting plate, a wire laying mechanism for driving the fibers to reciprocate laterally, a turntable rotatably connected to the mounting plate, two baffles symmetrically connected to the turntable, two rotating shafts symmetrically arranged on the turntable, and a cutting mechanism for cutting the fibers, wherein a reel for winding the fibers is sleeved on the rotating shaft, the two baffles and the two rotating shafts are arranged in a cross-shaped pattern, a rotating frame is sleeved on one end of the rotating shaft close to the turntable, a first linear driver is mounted on the rotating frame, a pressure plate is connected to the driving shaft of the first linear driver, and a limit block for limiting the rotation of the rotating frame is laterally slidably connected to the turntable; The rotating disk is provided with a driving mechanism for driving the rotating frame to move. The driving mechanism comprises a second linear driver installed on the rotating disk. The driving shaft of the second linear driver is connected with a moving ring.

[0007] By adopting the above technical solution, after most of the fiber is wound on one of the reels, the positions of the two reels are switched by rotating the turntable, and then the fiber continues to be wound through the bottom of the reel and the bottom of the baffle rod. When the fiber winding is completed, the first linear drive is started to drive the pressure plate to press the fiber, and then the fiber is cut by the cutting mechanism, and then the limit block is retracted into the turntable, so that the rotating frame rotates with the reel, and then the wire laying mechanism drives the fiber to move on the reel and wind the fiber through the rotation of the reel, and then the first linear drive is started to drive the pressure plate to move away from the reel, and then the second linear drive is started to drive the moving ring to move toward the rotating frame, and the moving ring abuts the rotating frame to move toward the turntable. As the wire laying mechanism drives the fiber to move back and forth, the fiber is completely wound around the reel, which is beneficial to improving the fiber winding quality and facilitating the removal of the wound fiber roll.

[0008] Optionally, a plurality of levers are arranged in an array on the inner side wall of the movable ring, and a receiving groove is provided on a side of each lever close to the turntable, and a retaining ring located in the receiving groove is fixedly connected to the inner side wall of the movable ring.

[0009] By adopting the above technical solution, since the cut end of the wire harness swings with the rotation of the reel, the winding quality of the wire harness is affected when the end of the wire harness is wound on the reel. When the moving ring moves in the direction away from the turntable, the moving ring can drive the lever to move. When the moving ring moves, it can push the fiber end to make it wind on the reel, and the lever can straighten the fiber end and make it stick to the surface of the reel. On the one hand, it can reduce the probability of the fiber end being thrown outside the fiber roll, and on the other hand, it can reduce the probability of the fiber end protruding and winding on the reel, thereby improving the winding quality of the fiber.

[0010] Optionally, the cutting mechanism includes a swing cylinder, a rotating plate and a cutter, the swing cylinder is mounted on a turntable, one end of the rotating plate is connected to a driving shaft of the swing cylinder, and the cutter is detachably connected to one end of the rotating plate away from the swing cylinder.

[0011] By adopting the above technical solution, after the fiber winding is completed, the swing cylinder is started to drive the rotating plate to rotate. As the rotating plate rotates, the cutter can be driven to cut the fiber, thereby realizing the fiber roll change to facilitate the winding of the next roll of fiber.

[0012] Optionally, the wire laying mechanism includes a fixed frame, a movable frame and a plurality of wire guide rods, the fixed frame is fixedly connected to the mounting plate, the movable frame is laterally slidably connected to the fixed frame, the wire guide rods are fixedly connected to the movable frame, and the fibers are wound onto the reel via the plurality of wire guide rods.

[0013] By adopting the above technical solution, the wire guide rod can guide and maintain the direction of the fiber, and drive the fiber to be wound onto the surface of the reel through the reciprocating movement of the moving frame.

[0014] Optionally, a limiting frame is fixedly connected to the movable ring, and the limiting frame is used to support the fiber when the cutter cuts the fiber.

[0015] By adopting the above technical solution, after the fiber winding is completed, the limiting frame is set up to provide support for the cutter when cutting the fiber, thereby reducing the probability that the cutter pushes the fiber to move after contacting the fiber and fails to cut the fiber, which is beneficial to realize the fiber roll change.

[0016] Optionally, the pressure plate is configured as an arc-shaped plate that matches the reel.

[0017] By adopting the above technical solution, the arrangement of the arc-shaped plate is conducive to protecting the fibers when the pressing plate presses the fibers, thereby reducing the probability that some fibers are squeezed and deformed.

[0018] Optionally, a rubber plate is fixedly connected to one side of the pressure plate close to the reel.

[0019] By adopting the above technical solution, the setting of the rubber sheet can protect the fiber again during the process of contacting with the fiber, thereby improving the fiber quality.

[0020] Optionally, a return spring is provided between the rotating frame and the rotating disk.

[0021] By adopting the above technical solution, the reset spring is arranged so that the rotating frame can be reset and continue to work after moving.

[0022] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects: 1. By pressing the fiber directly onto the reel so that all the fiber can be wound onto the reel, the probability of some fiber leaking out of the fiber roll is reduced, which is conducive to the removal of the fiber roll and the subsequent transportation of the fiber roll; 2. In the process of completely winding the bottom layer of fibers onto the reel, the swinging fiber ends can be attached to the reel and the fibers can be straightened to facilitate fiber winding; 3. The arrangement of the pressing plate, the arc plate and the rubber plate can protect the fibers when they are compressed, so that the device can adapt to different fiber types and protect their quality.

DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 5 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0026] This embodiment provides a fiber conveying device, referring to Figure 1 and Figure 2A fiber conveying device includes a mounting plate 1, a wire laying mechanism 2 for driving the fiber to move back and forth laterally, a turntable 3 rotatably connected to the mounting plate 1, two blocking rods 31 symmetrically connected to the turntable 3, two rotating shafts 32 symmetrically arranged on the turntable 3, a reel 5 sleeved on the rotating shaft 32, a pressing mechanism for pressing the fiber onto the reel 5, and a cutting mechanism 4 for cutting the fiber. The mounting plate 1 is in the shape of a rectangular parallelepiped as a whole. When the device is working, the mounting plate 1 can be fixedly mounted on the frame. The wire laying mechanism 2 is arranged on one side of the frame. The turntable 3 is arranged on the side of the mounting plate 1 away from the wire laying mechanism 2. The turntable 3 is in the shape of a cylinder and can be rotated on the mounting plate 1 by arranging a driving motor. The blocking rod 31 is fixedly connected to the turntable 3. The rotating shaft 32 is rotatably connected to the turntable 3. The two blocking rods 31 and the two rotating shafts 32 are distributed in a cross-shaped manner. The reel 5 is sleeved on the rotating shaft 32 to facilitate the winding of the fiber onto the reel 5. There are two clamping mechanisms, each of which is arranged on one side of the rotating shaft 32 close to the mounting plate 1, so that the fiber is pressed onto the reel 5 after the fiber is wound on one reel 5, so as to facilitate the limited cutting. The cutting mechanism 4 is arranged between the wire laying mechanism 2 and the rotating shaft 32. After the clamping mechanism presses the fiber, the cutting mechanism 4 runs to cut the fiber, so as to facilitate the winding of the fiber on another reel 5.

[0027] Reference Figure 1 The wire laying mechanism 2 includes a fixed frame 21, a movable frame 22 and a plurality of wire guide rods 23. The fixed frame 21 is fixedly connected to one side of the mounting plate 1. The movable frame 22 is slidably connected to the fixed frame 21, and the movable frame 22 can reciprocate laterally on the fixed frame 21. The wire guide rods 23 are fixedly connected to the movable frame 22 and are used to guide the direction of the fiber, thereby guiding the fiber so that the fiber can be wound on the reel 5. As the movable frame 22 reciprocates, the fiber can be wound on the reel 5.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4, each clamping mechanism includes a rotating frame 51, a first linear driver 52, a pressure plate 53 and a limit block 54. The rotating frame 51 is sleeved on the side of the reel 5 close to the mounting plate 1, and a return spring 511 is arranged between the rotating frame 51 and the turntable 3. The first linear driver 52 is fixedly mounted on the mounting plate 1. In this embodiment, the first linear driver 52 is a cylinder. In other embodiments, the first linear driver 52 can also be a device such as an oil cylinder or an electric push rod that can realize linear movement of the drive shaft. The pressure plate 53 is connected to the drive shaft of the first linear driver 52. The pressure plate 53 is set to an arc plate that is compatible with the reel 5, and a rubber plate 531 is fixedly connected to the side of the pressure plate 53 close to the turntable 3, so that the pressure plate 53 can protect the quality of the fiber when compressing the fiber, so that it can be kept when winding various fibers. In order to improve the surface quality of the fiber protection, the limit block 54 is connected to the turntable 3 by transverse sliding. The limit block 54 can limit the rotation of the rotating frame 51 in the initial state. When the pressure plate 53 presses the fiber, the limit block 54 retracts into the turntable 3, so that the rotating frame 51 rotates together with the rotating shaft 32. As the fiber is wound on the reel 5, the first linear drive 52 is started to drive the pressure plate 53 away from the reel 5, and the limit block 54 extends out of the turntable 3. Under the action of the limit block 54, the rotating frame 51 contacts the limit block 54 and stops rotating. Then the second linear drive 61 is started to drive the moving ring 62 to move toward the rotating frame 51. The moving ring 62 abuts against the rotating frame 51 and pushes the rotating frame 51 to move toward the turntable 3, so that the fiber covers the fiber pressed by the pressure plate 53, so that the first circle of fiber is completely located in the fiber roll.

[0029] Reference Figure 1 and Figure 3 The cutting mechanism 4 includes a swing cylinder 41, a rotating plate 42 and a cutter 43. The swing cylinder 41 is installed on the turntable 3. The swing cylinder 41 is a common pneumatic component, which is mainly used to realize mechanical actions of reciprocating motion or angular swing. Its working principle is usually to drive the piston movement inside the cylinder through the power of compressed gas, thereby converting it into mechanical energy. The rotating plate 42 is connected to the driving shaft of the swing cylinder 41, and the cutter 43 is detachably connected to the end of the rotating plate 42 away from the swing cylinder 41 by bolt connection.

[0030] Reference Figure 1 , Figure 3 and Figure 5The turntable 3 is provided with a pushing mechanism 6 for pushing the rotating frame 51 to move horizontally. The pushing mechanism 6 includes a second linear driver 61 and a moving ring 62. The moving ring 62 is fixedly connected with a limiting frame 621 on the side close to the cutter 43. The limiting frame 621 is used to provide support for the cutter 43 when the cutter 43 cuts the fiber. The second linear driver 61 is fixedly installed in the turntable 3. In this embodiment, the second linear driver 61 is a cylinder. In other embodiments, the second linear driver 61 can also be a device such as an oil cylinder or an electric push rod whose driving shaft can achieve linear movement. The moving ring 62 is connected to the driving shaft of the second linear driver 61. The moving ring 62 is located on the outside of the reel 5. A plurality of levers 7 are arranged in an array on the inner side wall of the moving ring 62, and the lever 7 is arranged as an elastic rod. A receiving groove 71 is opened on the side close to the turntable 3 of each lever 7. A retaining ring 72 located in the receiving groove 71 is fixedly connected to the inner side wall of the moving ring 62. After the pressure plate 53 presses the fiber, the fiber begins to be wound on the reel 5. However, the fiber end cut off by the cutting mechanism 4 will swing with the rotation of the rotating shaft 32. When the movable ring 62 moves in the direction away from the rotating frame 51, the movable ring 62 can also push the swinging fiber end and make the fiber end wind around the reel 5. At the same time, the movable ring 62 can drive the lever 7 to straighten the fiber end and make the fiber end stick to the surface of the reel 5. When the lever 7 straightens the fiber, the lever 7 does not swing due to the restriction of the retaining ring 72. When the movable ring 62 moves in the direction close to the rotating frame 51, the lever 7 can swing to prevent the fiber from being disordered, so as to facilitate the subsequent winding of the fiber. Then the movable ring 62 moves in the direction close to the rotating frame 51, can abut against the rotating frame 51 and push the rotating frame 51 to move, so as to facilitate the fiber winding work.

[0031] The implementation principle of a fiber conveying device in an embodiment of the present invention is as follows: first, after most of the fiber is wound on one reel 5, the turntable 3 is rotated to switch the positions of the two reels 5 so that the reel 5 with unwound fiber is rotated to the side close to the movable frame 22, and then the fiber passes from the bottom of the new reel 5 to the bottom of the baffle bar 31 and is then wound on the unwound reel 5. After the winding is completed, the first linear drive 52 is started to drive the pressure plate 53 to press the fiber, and at the same time the limit block 54 is retracted into the turntable 3, and then the second linear drive 61 is started to drive the moving ring 62 to move away from the rotating frame 51, and the moving ring 62 drives the fiber end to make it stick to the reel 5, and straightens the fiber through the lever 7, and then the second linear drive 61 is started to drive the moving ring 62 to move in the direction close to the rotating frame 51, and the moving ring 62 can abut against the rotating frame 51 and push the rotating frame 51 to move, thereby preventing the rotating frame 51 from interfering with the fiber winding, so as to facilitate the fiber winding.

[0032] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
