Description

Technical Field

[0001] This utility model belongs to the field of fiber material processing equipment, specifically, it relates to a conductive fiber take-up roller anti-deviation positioning structure. Background Technology

[0002] In the production process of conductive fibers (such as carbon fiber, graphene composite fiber, etc.), the roll material needs to be continuously wound up by winding rollers. Because the fiber material is lightweight, has a smooth surface and high conductivity, it is prone to axial sliding on the rollers during winding due to uneven tension and inertial offset, resulting in defects such as uneven edges and interlayer misalignment.

[0003] Traditional anti-deviation solutions often use fixed baffles or rigid limiting structures, but these have problems such as poor adaptability and material damage. For example, they cannot be flexibly adjusted according to the size of the roll material, or rigid contact can easily scratch the fiber surface and affect conductivity. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, the purpose of this utility model is to provide a conductive fiber take-up roller anti-deviation positioning structure, including a horizontally arranged take-up roller and supports symmetrically fixed at both ends of the take-up roller's axial direction. The take-up roller has a roll of material wound on it, and the top of the supports is provided with a groove in a direction perpendicular to the axis of the take-up roller.

[0005] Two limiting baffles are slidably embedded in the groove, and the inner end faces of the limiting baffles face the two sides of the roll of material of the take-up roller.

[0006] The outer end of each limit baffle is connected to the side wall of the bracket via an adjustment assembly;

[0007] At least three elastic pressing components are vertically fixed on the inner end face of the limiting baffle. Each elastic pressing component extends radially along the roll material and its end contacts the side of the roll material.

[0008] As a preferred embodiment, the elastic pressing assembly includes a guide sleeve that is fixed to the limiting baffle by bolts;

[0009] The guide sleeve is coaxially provided with an axially sliding ejector pin;

[0010] The ejector pin is provided with an annular flange at one end near the limiting baffle, and a compression spring is sleeved between the annular flange and the inner end face of the guide sleeve.

[0011] The inner wall of the guide sleeve is provided with two T-shaped guide rails extending axially, and the outer wall of the ejector pin is provided with a T-shaped block that slides with the T-shaped guide rails.

[0012] As a preferred embodiment, the end of the ejector pin extends out of the guide sleeve and is provided with a hemispherical contact.

[0013] As a preferred embodiment, the adjustment assembly includes a ball screw driven by a geared motor, the geared motor being fixed to the outer wall of the bracket via a flange;

[0014] The ball screw is disposed in the groove and threadedly connected to the slider outside the limiting baffle. The lower surface of the slider slides in contact with the bottom surface of the groove.

[0015] As a preferred embodiment, one side edge of the slide groove is provided with a scale line engraved on the upper surface of the bracket, and the extension direction of the scale line is perpendicular to the axis of the take-up roller; an arrow-shaped pointer is fixed on the upper surface of the slider, the tip of the pointer points to the scale line, and the pointer is connected to the slider by a countersunk screw.

[0016] As a preferred embodiment, a gradient density silicone pad is embedded between the contact surfaces of the limiting baffle and the slide groove.

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] A conductive fiber take-up roller anti-offset positioning structure includes a horizontally arranged take-up roller 1 and brackets 2 symmetrically fixed at both ends of the axial direction of the take-up roller 1. A roll of material 6 is wound on the take-up roller 1. The top of the bracket 2 is provided with a groove 201 in a direction perpendicular to the axis of the take-up roller 1 to accommodate different widths of rolls.

[0025] Two limiting baffles 3 are slidably embedded in the slide groove 201, and the inner end face of the limiting baffles 3 faces both sides of the roll 6 of the take-up roller 1.

[0026] The outer end of each limiting baffle 3 is connected to the side wall of the bracket 2 via the adjusting assembly 4;

[0027] At least three elastic pressing components 5 are vertically fixed on the inner end face of the limiting baffle 3. Each elastic pressing component 5 extends radially along the roll 6 and its end contacts the side of the roll 6. The three elastic pressing components 5 are distributed in a triangular pattern.

[0028] The limiting baffle 3 is driven by the adjusting component 4. When it moves inward, it can contact the edge of the roll material 6 through the elastic pressing component 5. The three sets of elastic pressing components 5, which are triangularly distributed, such as the upper, middle and lower points, can form a stable three-point support surface. The triangular distribution can provide multi-directional constraint force. Compared with the linear arrangement of single or double point support, it is more effective in suppressing the radial and axial composite displacement of the roll material and preventing the roll material 6 from tilting or twisting due to inertia or tension fluctuations during winding.

[0029] In a preferred embodiment, the elastic pressing assembly 5 includes a guide sleeve 503 that is fixed to the limiting baffle 3 by bolts;

[0030] The guide sleeve 503 has a coaxially slidable ejector pin 501 inside;

[0031] The end of the ejector pin 501 near the limiting baffle 3 is provided with an annular flange 505, and a compression spring 502 is sleeved between the annular flange 505 and the inner end face of the guide sleeve 503.

[0032] The inner wall of the guide sleeve 503 is provided with two T-shaped guide rails 506 extending along the axial direction, and the outer wall of the ejector pin 501 is provided with a T-shaped block 507 that slides with the T-shaped guide rails 506.

[0033] The end of the ejector pin 501 extends out of the guide sleeve 503 and is provided with a hemispherical contact 504.

[0034] The ejector pin 501 slides with the T-shaped guide rail 506 of the guide sleeve 503 through the T-shaped block 507, which restricts the rotation of the ejector pin 501 and ensures that the pressing direction is always perpendicular to the side of the roll material. The compression spring 502 provides flexible pressing force. When the roll material deviates slightly, the ejector pin 501 can axially retract to buffer and avoid rigid impact. The hemispherical contact 504 can reduce the contact area, reduce frictional resistance, and at the same time disperse pressure to protect the fiber surface.

[0035] During winding, the ejector pin 501 continuously presses against the edge of the roll material under the action of the compression spring 502. The offset force pushes the ejector pin to retract, and the change in the compression amount of the compression spring 502 provides feedback on the offset trend. The position of the limit baffle 3 is corrected in real time by the adjustment component 4.

[0036] In a preferred embodiment, the adjustment component 4 includes a ball screw 405 driven by a geared motor 404, and the geared motor 404 is fixed to the outer wall of the bracket 2 by a flange.

[0037] The ball screw 405 is set in the slide groove 201 and is threadedly connected to the slider 403 on the outside of the limit baffle 3. The lower surface of the slider 403 slides in contact with the bottom surface of the slide groove 201.

[0038] The geared motor 404 drives the ball screw 405 to rotate, which in turn moves the slider 403 within the slide groove 201, thereby achieving precise position adjustment of the limit baffle 3. The geared motor 404 can be a harmonic geared motor, which has high precision and low backlash characteristics and is suitable for fine-tuning scenarios.

[0039] As a preferred embodiment, one side edge of the chute 201 is provided with a scale line 7 engraved on the upper surface of the bracket 2, and the extension direction of the scale line 7 is perpendicular to the axis of the take-up roller 1.

[0040] An arrow-shaped pointer 8 is fixed on the upper surface of the slider 403. The tip of the pointer 8 points to the scale line 7. The pointer 8 is connected to the slider 403 by a countersunk screw.

[0041] The scale line 7 marks the distance the slider 403 moves in the slide groove 201. The pointer 8 is fixed to the slider 403. The operator can intuitively read the scale at the position of the limit baffle 3 to ensure symmetrical adjustment on both sides.

[0042] As a preferred embodiment, a gradient density silicone pad 9 is embedded between the contact surfaces of the limiting baffle 3 and the slide groove 201. The gradient density structure, which is hard inside and soft outside, absorbs the vibration of the take-up roller and provides sliding resistance, preventing the limiting baffle 3 from moving accidentally in the non-adjusted state and improving the stability of the system.

[0043] The complete workflow of this utility model is as follows:

[0044] 1. Initial settings: Based on the width of the roll material 6, the limiting baffles 3 on both sides are driven to move along the slide groove 201 to the predetermined position by adjusting the component 4, and the pointer 8 points to the value corresponding to the scale line 7.

[0045] 2. Elastic pressing contact: The elastic pressing component 5 pin 501 inside the limiting baffle 3 contacts the edge of the roll material 6 under the action of the compression spring 502, forming a triangular constraint surface.

[0046] 3. Dynamic adjustment: During the winding process, if the roll material 6 deviates, the ejector pin 501 will be compressed and retracted. The compression amount of the compression spring 502 will trigger the sensor (optional) or be observed manually. The position of the limit baffle 3 can be finely adjusted by adjusting the component 4 to correct the deviation in real time.

[0047] 4. Vibration reduction: Silicone pad 9 absorbs vibration and ensures smooth winding.
