Embodiment 1

[0033] See Figure 1 , a prepreg fiber anti-screw mechanism, including box 1, drive assembly 2, lift assembly 3, guide rod 4 and fixing rod 5.

[0034] The top of the cabinet 1 is provided with an opening for the feed and outlet of the fiber tow 11. Drive assembly 2 is mounted at the top of one side wall of the enclosure 1. In the present embodiment, the drive component 2 is a motor 21, the drive end of the drive component 2 is the hinge of the motor 21, the motor 21 is mounted at the top of the right wall of the box 1, the hinge of the motor 21 is coaxially fixed to the top of the lifting assembly 3.

[0035] Lifting assembly 3 is installed in the box 1, the top of the lifting assembly 3 is connected to the drive end of the drive assembly 2. In the present embodiment, the lifting assembly 3 is a ball screw 31. Ball screw bearings can also be used for lifting assembly 3. The lifting end of the lifting assembly 3 is the nut of the ball screw 31, the nut of the ball screw 31 sli...

Embodiment 2

[0040] On the basis of Example 1, please refer to it together Figure 2 - Figure 4 , the difference of the present embodiment is:

[0041] Guide rod 4 has a circular arc angle of the edge, the edge parallel to the axis of the fixing rod 5, and the edge is used to form a sliding tension with the fiber tow. In the present embodiment, the guide rod 4 selects a triangular prism, the left and right ends of the triangular beam and the inner wall of the box 1 are sliding in conjunction, one or two prisms in the triangular prism can be used with the fiber tow in a sliding tension fit. The edge of the triangular prism is combined with the sliding of the fiber tow, so as to facilitate the formation of corners of the fiber tow, and the direction of movement of the fiber tow is adjusted, which not only avoids the screwing of the fiber tow in box 1, but also facilitates the adjustment of the length of the fiber tow in box 1.

[0042]At the same time, the motor 21 selects a servo motor 21. Plea...

Embodiment 3

[0051] On the basis of Example 1, the difference of the present embodiment is:

[0052] The inner side wall of the cabinet 1 is provided with four chutes 12, the slots of the four chutes 12 are set in the height direction of the box 1, the four ball screws 31 are located in the four chutes 12, the nut slide of the ball screw 31 is mounted in the chute 12. Ball screw 31 slides in the chute 12, the chute 12 limits the nut of the ball screw 31, while also avoiding fibers wrapped around the ball screw 31, avoiding the occurrence of screws of the fibers.

[0053] At the same time, the guide rod 4 uses four prisms, and the left and right ends of the four prisms are sliding with the inner wall of the box 1. The four prisms can increase the sliding and cooperation with the fiber tow to form a corner, which is convenient for adjusting the direction of movement of the fiber tow multiple times, thereby further preventing the twisting of the fiber tow and achieving a flatter fiber during the ...

Abstract

The invention relates to the technical field of twisting prevention devices, in particular to a prepreg fiber yarn twisting prevention mechanism. Comprising a box body, a driving assembly, a lifting assembly, a guide rod and a fixing rod; the box body is provided with an opening used for feeding and discharging fiber tows, the driving assembly is installed at the top end of one side wall of the box body, the lifting assembly is installed in the box body, the top end of the lifting assembly is connected with the driving end of the driving assembly, and the guide rod and the fixing rod are parallel and are both installed in the box body. A gap exists between the guide rod and the fixing rod, the guide rod is connected with the lifting end of the lifting assembly, when the driving end of the driving assembly is in a working state, the lifting end of the lifting assembly can drive the guide rod to slide in the height direction of the box body, and the guide rod and the fixing rod are both used for being in slidable tensioning fit with fiber tows. The invention aims to solve the problem that fiber tows are easy to twist into balls and need to be spread manually in the yarn spreading process of prepreg production.

Description

Technical field [0001] The present invention relates to the technical field of anti-screw device, specifically to a prepreg fiber anti-screwing mechanism. Background [0002] Prepreg is a resin matrix impregnated with continuous fibers or fabrics under strictly controlled conditions to make a composition of a resin matrix and an enhancer. For example, carbon fiber prepreg cloth is a composite material that is processed by processing epoxy resin on carbon fiber after high pressure and high temperature technology, which is made of carbon fiber yarn, epoxy resin, release paper and other materials, and processed by coating, hot pressing, cooling, laminating and winding. [0003] In the production of prepreg fabric yarn, it is necessary to pull the fiber tow out of the fiber reel, and the fiber tow into the yarn spreading equipment for the yarn spreading process, as the fiber on the fiber reel is pulled out, the diameter of the fiber reel becomes smaller, so that the distance between...
