Description

Technical Field

[0001] This invention relates to the field of fiber processing technology, specifically to an anti-clogging polymer fiber dispersion device. Background Technology

[0002] Before modification, mixing, and wet spinning, polymer fibers, chemical staple fibers, and modified fiber raw materials all require dispersion treatment to eliminate fiber clumps and entanglement, ensuring uniform distribution of single filaments. The dispersion uniformity and anti-entanglement and anti-clogging capabilities of the dispersion device directly determine the quality of subsequent spinning and composite products. Traditional fiber dispersion roller equipment has several prominent defects in the batch processing of polymer fibers:

[0003] Traditional dispersing equipment has fixed, integrated rotating disc supports on both sides, and the distance between the left and right rotating discs is not adjustable. It can only install fiber carrying rollers of a single length. When enterprises produce multiple types and different widths of polymer fibers, they need to replace the entire set of frame tooling. The disassembly and assembly process is cumbersome, the downtime for changing the model is long, and the processing efficiency of the production line is greatly reduced.

[0004] Traditional load-bearing rollers and drive turntables use a common bolt flange locking structure. When cleaning entangled fibers or replacing dispersing needles, multiple fasteners need to be removed to take off the roller body. High molecular fibers are highly viscous and easily adhere to the surface of the dispersing needles, resulting in a large workload for daily cleaning and maintenance. The cumbersome disassembly and assembly further prolongs downtime. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an anti-clogging polymer fiber dispersion device.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: an anti-clogging polymer fiber dispersion device, comprising a mounting frame, a dispersion component, and an assembly component. The assembly component includes a fixed frame, a sliding frame, a mounting plate, a movable frame, a screw, a turntable, a first motor, and a second motor. The fixed frame is disposed at one lower end of the mounting frame, and a sliding frame is disposed below the mounting frame. A sliding groove is disposed below the sliding frame, and a screw is rotatably disposed within the sliding groove. The mounting plates are symmetrically disposed on the left and right sides below the fixed frame. A first motor is disposed below one mounting plate, and a second motor is disposed below the other mounting plate. The movable frame extends into the sliding groove and is threadedly connected to the screw. Turntables are disposed on adjacent sides of the movable frame and the fixed frame. The output end of the first motor passes through the fixed frame and is connected to the corresponding turntable. The output end of the second motor passes through the sliding frame and is connected to the screw. The dispersion component includes a carrying roller and dispersion needles. The carrying roller is inserted into the turntable on both the left and right sides, and a plurality of dispersion needles are disposed on the carrying roller.

[0009] To ensure the stability of the bearing roller assembly, the present invention is improved by providing a spline on the turntable and a keyway on the bearing roller.

[0010] To ensure the stability of the connection between the mounting bracket and the fixing bracket, the present invention is improved by providing a reinforcing rib on the mounting bracket that is connected to the fixing bracket.

[0011] Preferably, the mounting bracket is provided with bolts that connect to the sliding frame.

[0012] Preferably, both the first motor and the second motor are servo motors.

[0013] Preferably, the mounting bracket is also provided with mounting holes at its four corners.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides an anti-clogging polymer fiber dispersion device, which has the following beneficial effects:

[0016] This anti-clogging polymer fiber dispersion device has a fixed frame on one side and a movable frame mounted on a sliding frame on the other side. A second motor drives the screw to rotate, which can adjust the clamping distance between the two turntables. It can be adapted to fiber carrying rollers of various lengths. When processing polymer fibers of different widths and types, there is no need to replace the entire frame tooling. The changeover can be completed simply by adjusting the distance with the motor, which greatly shortens the downtime for material changeover and improves the continuous processing efficiency of the production line.

[0017] The two ends of the carrying roller are quickly connected to the turntable via splines, eliminating the need to disassemble a large number of flange bolts. When cleaning the entangled fibers adhering to the dispersing needles or replacing worn dispersing needles, the carrying roller can be pulled out horizontally, simplifying the disassembly and assembly steps, reducing equipment downtime for cleaning, and reducing production losses caused by fiber entanglement from an operation and maintenance perspective. At the same time, the spline connection can stably transmit torque, and the roller body will not slip during high-speed dispersion. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-4A clogging-resistant polymer fiber dispersion device includes a mounting frame 1, a dispersion component, and an assembly component. The assembly component includes a fixed frame 2, a sliding frame 3, a mounting plate 4, a movable frame 5, a screw 6, a turntable 7, a first motor 8, and a second motor 9. The fixed frame 2 is located at one lower end of the mounting frame 1. The sliding frame 3 is also located below the mounting frame 1. A sliding groove is provided below the sliding frame 3, and the screw 6 is rotatably mounted in the sliding groove. The mounting plates 4 are symmetrically arranged on the left and right sides below the fixed frame 2, and the first motor 8 is located below one of the mounting plates 4. A second motor 9 is also provided below the other mounting plate 4. The upper part of the movable frame 5 extends into the slide groove and is threadedly connected to the screw 6. Turntables 7 are provided on the adjacent sides of the movable frame 5 and the fixed frame 2. The output end of the first motor 8 passes through the fixed frame 2 and is connected to the corresponding turntable 7. The output end of the second motor 9 passes through the slide frame 3 and is connected to the screw 6. The dispersing component includes a carrying roller 10 and dispersing needles 11. The left and right sides of the carrying roller 10 are inserted into the turntables 7. Several sets of dispersing needles 11 are provided on the carrying roller 10.

[0025] Mounting bracket 1 has a fixed mounting bracket 2 on one side and a sliding frame 3 on the other side. The sliding frame 3 has a sliding groove with a screw 6 inside. The upper end of the moving bracket 5 is threaded onto the screw 6. The output end of the second motor 9 is connected to the screw 6 and is responsible for the spacing adjustment action.

[0026] The second motor 9 drives the screw 6 to rotate in the forward direction. The screw 6 drives the moving frame 5 to move outward along the slide groove. The distance between the two turntables 7 increases, allowing a longer fiber carrying roller 10 to be placed.

[0027] The second motor 9 drives the screw 6 to rotate in the opposite direction, the moving frame 5 moves closer to the fixed frame 2, the distance between the two turntables 7 is reduced, and the short bearing roller 10 is adapted.

[0028] The servo motor has a power-off self-locking feature and stops after being adjusted to the target width. The screw 6 thread pair is self-locking, and the moving frame 5 will not be displaced by rotational vibration. It always keeps the two turntables 7 on the same axis and avoids the fiber from being wrapped on one side due to the movement of the roller.

[0029] The first servo motor at the bottom of the fixed frame 2 independently drives the turntable 7 on the same side, and the two ends of the bearing roller 10 are connected to the turntables 7 on both sides through splines 12.

[0030] The motor output torque is directly transmitted to the turntable 7, and then the spline 12 meshes and synchronously drives the bearing roller 10 to rotate at high speed. Multiple sets of dispersing needles 11 on the surface of the bearing roller 10 rotate synchronously with the roller body, continuously tearing and breaking up the clumps of polymer fibers to eliminate fiber entanglement.

[0031] The 12-tooth spline structure transmits torque evenly, and there is no slippage or freewheeling problem during high-speed operation; at the same time, the two-sided turntables 7 clamp the bearing rollers 10 in both directions, and the rollers are subjected to balanced forces at both ends, with no axial offset, which greatly reduces the phenomenon of fibers accumulating and entangled on one side.

[0032] The second motor 9 expands the distance between the two turntables 7, and the splines 12 at both ends are completely separated from the keyways, allowing the bearing roller 10 to be pulled out directly laterally without disassembling the flange or tightening the bolts 14. This allows for the quick cleaning of sticky fibers wrapped around the dispersing needle 11 or the replacement of worn dispersing needles 11.

[0033] After cleaning, align the keyways at both ends of the bearing roller 10 with the splines 12 on both sides and push them in. Then, control the second motor 9 again to reduce the distance between the turntables 7, complete the bidirectional clamping and positioning, and immediately resume the dispersed operation.

[0034] A reinforcing rib 13 is added between the mounting frame 1 and the fixed frame 2 to form a triangular reinforcement structure, which greatly improves the rigidity of the whole machine structure. When the bearing roller 10 rotates at high speed, the frame vibration is significantly reduced, and the coaxiality of the two turntables 7 is stable, further suppressing fiber entanglement.

[0035] The sliding frame 3 is detachably fixed to the bottom of the mounting bracket 1 by bolts 14. If the internal screw 6 is worn or stuck, the sliding assembly can be disassembled and repaired by loosening bolts 14 separately without disassembling the whole machine.

[0036] Mounting bracket 1 has pre-drilled mounting holes at its four corners, allowing the entire device to be locked onto any position in the spinning or mixing equipment using bolts 14, making it compatible with various production line layouts.
