Description

carbon fiber wire feeding device Technical Field

[0001] This utility model belongs to the field of wiring machine technology, specifically relating to a carbon fiber wire feeding device. Background Technology

[0002] Carbon fiber materials, with their high strength, lightweight, and corrosion resistance, have been deeply integrated into high-end manufacturing and consumer sectors, such as sports equipment, industrial transmission components, and robot structural parts. Carbon fiber thread feeding devices, as a core component of automated lay-up and sewing equipment, were developed due to the urgent need in the industrialization of carbon fiber to address issues such as material property adaptation, improved process precision, and domestic substitution. The specific reasons are as follows:

[0003] 1. Brittle fracture control: The elongation at break of carbon fiber is only 0.5%-2%. The tension fluctuation of traditional wire feeding devices leads to a wire breakage rate of over 15%. A constant tension wire feeding system (fluctuation ≤ ±0.5%) needs to be developed to ensure continuous production.

[0004] 2. Traditional wire feeding devices can only feed wire bundles of a single specification and cannot be adapted to multiple types of wire bundles;

[0005] 3. Traditional carbon fiber stitching equipment uses small spools, resulting in a small amount of carbon fiber stored, which prevents continuous production over long periods and leads to low production efficiency. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a carbon fiber feeding device. This device mainly solves the problems of carbon fiber feeding coiling, single feeding wire bundle, uncontrollable tension, and small amount of carbon fiber that can be stored.

[0007] This utility model is achieved through the following technical solution:

[0008] The carbon fiber feeding device includes: a material rack, a tension adjustment section, and a guide section.

[0009] The material rack section is fixed to the machine beam and is used to store and convey carbon fiber rolls;

[0010] The guide section is fixed to the tension adjustment section by screws and is used to adjust the direction of the carbon fiber bundle for wiring.

[0011] The tension adjustment section is used to adjust the tension of the carbon fiber bundle to ensure that the bundle is in a constant tension state.

[0012] The material rack component includes: material rack mounting base, carbon fiber fixing shaft, clamping seat, and fixing block.

[0013] The carbon fiber fixing shaft is fixedly installed on the material rack mounting base by means of a bracket and a fixing block, and is used to fix the carbon fiber material shaft.

[0014] The tension adjustment section includes: a column, a geared motor, a motor mounting base, a bearing housing, a rubber roller, a movable shaft bracket, a tension spring, a hinge, and a belt.

[0015] The geared motor is fixedly mounted on the motor mounting bracket;

[0016] The motor mounting bracket is fixedly installed on the bearing housing;

[0017] The rubber rollers are in two sets, which are fixedly installed on the shaft seat box and the movable shaft frame, respectively;

[0018] The aforementioned geared motor drives rubber rollers to engage via a belt, thereby propelling the carbon fiber bundles into feed.

[0019] One end of the movable shaft frame is fixed to the column by a hinge, and the other end is fixedly connected to the shaft seat box by a tension spring. When carbon fiber bundles of different specifications pass through the rubber roller, the pressure of the rubber roller is adjusted by the tension spring to ensure that the carbon fiber bundles are always under constant pressure.

[0020] The guide section includes: bracket mounting plate, wire feed sensor mounting plate, swing arm, wire stop wire, and sensor.

[0021] The sensor is fixedly mounted on the sensor mounting plate;

[0022] The sensor mounting plate is fixedly mounted on the bracket mounting plate, and the motor speed is controlled by sensing the carbon fiber bundle to control the speed of feeding the carbon fiber bundle.

[0023] The guide wires are fixed on the swing arm, and the carbon fiber bundle passes between the two guide wires to achieve the purpose of guidance.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This invention overcomes the problems of traditional carbon fiber feeding devices, such as limited wire bundle specifications, small wire bundle storage capacity, and poor product quality and instability due to large fluctuations in carbon fiber tension, which make it impossible to adjust to a suitable tension. Through the design of this invention, product quality and production efficiency are improved, and production costs are reduced. Attached Figure Description
