Description

Technical Field

[0001] The invention relates to the field of carbon fiber prepreg cutting equipment, in particular to an automatic slitting device for carbon fiber prepreg. Background Art

[0002] In the field of modern industrial manufacturing, carbon fiber prepregs are widely used in many high-end industries such as aerospace, automobile manufacturing, and sports equipment due to their excellent properties such as high strength, low density, and corrosion resistance. With the rapid development of these industries, the demand for carbon fiber prepregs has not only continued to grow in quantity, but also put forward more stringent requirements in terms of quality and processing accuracy.

[0003] In the processing of carbon fiber prepreg, slitting is a crucial link. Traditional slitting methods have many disadvantages. In terms of cleaning, many prepregs are simply wiped or washed before slitting, which makes it difficult to effectively remove fine dust and debris attached to the surface. These impurities can easily enter between the tool and the prepreg during slitting, which will not only cause the slitting tool to wear quickly, increase the frequency of tool replacement and production costs, but also seriously affect the slitting accuracy and quality, causing the slitting products to have problems such as uneven cuts and dimensional deviations, which cannot meet the manufacturing needs of high-end products.

[0004] During the slitting process, it is difficult for traditional slitting equipment to accurately control the slitting width. Operators can only make manual adjustments based on experience, which is not only inefficient, but also difficult to ensure uniform spacing between the slitting wheels, resulting in inconsistent widths of the slitting products, reducing the product qualification rate and production efficiency. At the same time, since carbon fiber prepregs will generate internal stress during production and transportation, and the traditional slitting process lacks effective stress release measures, stress concentration during slitting can easily cause defects such as curling and cracking of product edges, further affecting product quality and the smooth progress of subsequent processing. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an automated slitting device for carbon fiber prepreg, which solves the problems of impurities affecting the slitting effect and tool life, inconvenient slitting width adjustment, stress concentration causing product defects, inconvenient winding, etc. during the slitting of carbon fiber prepreg, thereby comprehensively improving the slitting quality and production efficiency.

[0025] Furthermore, winding rollers 44 are movably installed on the upper and lower sides of the interior of the winding frame 43. The winding rollers 44 are used to wind up the slit carbon fiber prepreg. A second synchronous wheel 45 is fixedly installed on one end of the winding roller 44, and the outer diameters of the second synchronous wheel 45 are connected by a second synchronous belt 46. The cooperation between the second synchronous wheel 45 and the second synchronous belt 46 enables the two winding rollers 44 to rotate synchronously. A third motor 47 is fixedly installed on one side of the winding frame 43, and the driving end of the third motor 47 is fixedly installed on one end of the winding roller 44 on one side. The third motor 47 provides power for the rotation of the winding roller 44.

[0026] Working principle: First, the carbon fiber prepreg to be cut is pulled out from the unwinding roller 2, and one side is passed through the middle opening 4 of the cleaning box 3 and under the slitting wheel 33 of the slitting frame 30. After the end part of the prepreg is manually cut, it is wound on the outer diameter of the upper and lower winding rollers 44 in a staggered manner, and then the third motor 47 is started to drive the winding roller 44 on one side to rotate, and then the transmission effect of the second synchronous wheel 45 and the second synchronous belt 46 is used to make the two winding rollers 44 rotate at the same time, and the prepreg on the unwinding roller 2 is started. First, the cleaning water is introduced through the water inlet pipe 14, and the cleaning water enters the circular water pipe 12 and is sent to each cleaning bin 5 through the branch pipe 13. Then the first motor 11 is started, and the first motor 11 is driven by the first motor 11. 11 drives the upper rotating shaft 9 to rotate, drives the first synchronous wheel 18 on the rotating shaft 9 to rotate, utilizes the transmission of the first synchronous belt 19 to drive the lower rotating shaft 9 to rotate synchronously, thereby drives all the worms 10 on the two rotating shafts 9 to rotate, the rotating worms 10 drive all the worm wheels 8 and the short shaft 6 to rotate through the meshing transmission, thereby drives all the cross brush plates 7 to rotate, the high-speed rotating cross brush plates 7 will break the cleaning water entering the cleaning chamber 5 into fine water droplets, these fine water droplets are mixed with air to form a high-speed water-gas fluid, thereby cleaning the upper and lower outer surfaces of the prepreg, washing away the dust and debris on the surface of the raw material, preventing these impurities from entering between the tool and the prepreg during the slitting process, affecting the slitting effect, reducing tool wear, and improving slitting efficiency and quality. When the negative pressure fan 16 is started, the negative pressure fan 16 quickly pumps the waste liquid collection box 15 to a vacuum state, and the strong atmospheric pressure discharges the sewage mixed with dust and dirt generated during cleaning into the waste liquid collection box 15 through the drain pipe 17, which can not only improve the cleaning effect, but also keep a certain humidity on the surface of the prepreg to prevent the prepreg from absorbing too much moisture and reducing the performance. At the same time, it prevents the surface of the prepreg from being too dry and causing fiber embrittlement. The cleaned prepreg is discharged from one side of the opening 4 through the lead-out roller 29, and the rotating shaft 9 will also drive the driving wheel 26 to rotate when rotating. The rotating driving wheel 26 drives the driven wheel 27 and the light rod 21 to rotate through the transmission belt 28. The light rod 21 drives the cams 22 on both sides to rotate, and the cam 22 drives the connecting rod 2 3 moves with the movement, and under the limiting action of the guide rod 25, the connecting rod 23 drives the shaking plate 24 at the bottom to do reciprocating motion up and down, and beats the surface of the prepreg to release its internal stress, which can effectively avoid edge curling and cracking caused by stress concentration during the slitting process, and improve the subsequent slitting quality. Then the prepreg enters the slitting frame 30, and the second motor 41 is started. The drive shaft 38 is driven to rotate by the second motor 41, and the keyway 40 of the spline 39 is used to limit the cooperation effect to drive all the slitting wheels 33 to rotate, so as to slitting the prepreg. When the slitting width needs to be adjusted, the adjusting shaft 34 is driven to rotate by rotating the hand wheel 37. When the adjusting shaft 34 rotates, it will drive all the arc-shaped slide grooves 35 on the outer surface to rotate.When the arc-shaped slide groove 35 rotates, the round pin 36 will slide in the arc-shaped slide groove 35, and then the limiting effect of the slide rod 31 will make all the movable blocks 32 and the slitting wheels 33 shrink inward or expand outward at the same time, so as to control the slitting width. Since the pitch of the arc-shaped slide groove 35 increases from the inside to the outside, all the slitting wheels 33 always keep the same distance when shrinking or expanding, which is convenient for slitting according to different needs. The prepreg after slitting is rolled up on the two winding rollers 44 in an up-and-down staggered manner, which is convenient for subsequent processing.
