Description

[Technical field]

[0001] The invention relates to the technical field of carbon fiber board recycling and processing, in particular to a carbon fiber board crusher capable of controlling crushing size. [Background technology]

[0002] Carbon fiber board has good properties such as high tensile strength, corrosion resistance, shock resistance, and impact resistance, and is widely used in lightweight, high-strength and high-modulus structural materials. Carbon fiber is a recyclable material. The existing recycling methods are generally divided into two types: one is to separate the carbon fiber and resin in the carbon fiber board and then recycle it, but this method requires large investment and complex process; the other is to use a carbon fiber board crusher to crush the carbon fiber board. The multiple cutters in the existing carbon fiber board crusher are generally set in a blade-to-blade manner. When the carbon fiber board is crushed, the carbon fiber board is crushed by the collision of the relatively set blades. The composite size of the crushed material will leak out from the filter with mesh set under the cutter, and the non-conforming size will continue to be crushed. However, this crusher cannot effectively control the particle size of the crushed material due to the setting of the cutter, and during the crushing process, the carbon fiber board is crushed by collision before leaking out of the filter, which makes it easy for the carbon fiber to be broken up, resulting in the phenomenon of fluffy carbon fiber, which is not conducive to the subsequent recycling of carbon fiber, and may even block the filter, causing abnormal equipment shutdown and other defects.

[0003] In view of this, the present invention provides a carbon fiber board crusher capable of controlling crushing size to solve the above technical problems. [Summary of the invention]

[0004] In order to solve the technical problems that the existing carbon fiber board crusher cannot effectively control the particle size of the crushed material when crushing the carbon fiber board, and easily breaks up the carbon fiber during the crushing process, making the carbon fiber fluffy and not conducive to carbon fiber recovery, the present invention provides a carbon fiber board crusher with controllable crushing size to solve the above problems.

[0009] The discharging chute is communicated with the scabbard and is used for discharging the crushed carbon fiber board fragments.

[0010] Preferably, the two rotation axes in the scabbard are arranged in parallel.

[0011] Preferably, the cross section of the rotating shaft is a polygon, and the middle of the cutting blade is a polygonal hollow portion corresponding to and matching the cross section of the rotating shaft.

[0012] Preferably, the spacing between the cutting blades on the two rotating shafts can be adjusted by replacing cutting blades with different diameters, thereby adjusting the length of the carbon fiber board fragments after being crushed; the width of the carbon fiber board fragments after being crushed can be adjusted by replacing cutting blades with different numbers of teeth and different widths of cutting edges.

[0013] Preferably, the cutting edge of the cutting blade may be subjected to a coating process (surface modification process) or a carbide coating process to improve the wear resistance, strength, hardness and corrosion resistance of the cutting edge.

[0014] The beneficial effect of the present invention is that the carbon fiber board crusher with controllable crushing size can adjust the size of the crushed carbon fiber board by replacing the cutting blade, the cutting blade is easy to replace, the cross-section of the crushed carbon fiber board is neat and the dust is small, and at the same time, the carbon fiber board can be prevented from being broken up and fluffy during the crushing process, thereby improving the efficiency and quality of the carbon fiber board crushing.
