Description

Technical Field

[0001] The utility model specifically relates to a carbon fiber waste cutting device. Background Technique

[0002] Carbon fiber refers to high-strength and high-modulus fibers with a carbon content of more than 90%. It has the highest heat resistance among all chemical fibers. It is made from acrylic and viscose fibers through high-temperature oxidation and carbonization. It is an excellent material for manufacturing high-tech equipment such as aerospace. Carbon fiber is mainly composed of carbon elements and has characteristics such as high temperature resistance, anti-friction, electrical conductivity, thermal conductivity, and corrosion resistance. Its shape is fibrous, soft, and can be processed into various fabrics. Due to the preferred orientation of its graphite microcrystal structure along the fiber axis, it has high strength and modulus along the fiber axis direction. Carbon fiber has a small density, so its specific strength and specific modulus are high. The main use of carbon fiber is as a reinforcing material to be compounded with resins, metals, ceramics, and carbon to manufacture advanced composite materials. Carbon fiber reinforced epoxy resin composite materials have the highest specific strength and specific modulus among existing engineering materials.

[0003] Currently, during the processing of carbon fiber waste, it needs to be cut to reduce its volume for subsequent secondary processing and treatment. However, the existing cutting devices are complex to operate, require multiple people to press and use, have low practicability, and low working efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a carbon fiber waste cutting device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A carbon fiber waste cutting device includes a base, two bearing plates for placing carbon fiber waste to be cut, a cutting head, a stretching mechanism, and a pressing mechanism. The cutting head is arranged on the base. A gap is reserved between the two bearing plates. The bearing plates are installed on the base through the stretching mechanism, so that the gap is located directly above the cutting head.

[0006] Among them, the pressing mechanism applies pressure to the bearing plates, and the bearing plates slide arcuately towards both sides under the elasticity of the stretching mechanism, so that the carbon fiber waste falls through the gap and abuts against the cutting head to achieve cutting.

[0007] Preferably, the stretching mechanism includes connecting columns respectively arranged on both sides of the bearing plates and on the base, and a stretching spring is arranged between the connecting columns.

[0008] Preferably, pins are respectively arranged inside the base towards both sides of the bearing plates. The two bearing plates are connected through an adapter piece. Waist-shaped holes adapted to the pins are formed on the surface of the adapter piece, and the adapter piece is clamped on the pins through the waist-shaped holes to realize the deflection of the two bearing plates.

[0009] Preferably, support frames are provided on both sides of the base, a cross beam is provided between the two support frames, the pressing mechanism includes a movable block arranged on the cross beam, and two arc-shaped saw teeth are symmetrically arranged on both sides of the movable block respectively.

[0010] Preferably, pressing plates are arranged on the inclined downward sides of the two saw teeth away from each other.

[0011] Preferably, a gear for transmission is arranged between the two saw teeth, and a rotating handle is arranged on the upper surface of the gear.

[0012] Preferably, a fixed block is arranged outside the movable block, sliding grooves are opened on both outer sides of the fixed block, a lifting block slides on the fixed block through the sliding grooves, a reset spring is arranged between the lifting block and the fixed block, and the lifting block is located vertically below the end of the rotating handle. A roller is arranged on the lower surface of the lifting block.

[0013] The technical effects and advantages of the present utility model: For this carbon fiber waste cutting device, the carbon fiber waste to be cut is laid flat on the surfaces of the two bearing plates. Rotate the rotating handle. Through the engagement of the gear with the two saw teeth, the two saw teeth move in opposite directions respectively, driving the two pressing plates to press the bearing plates. At this time, with the deformation of the tension spring, the two bearing plates move arc-shaped towards both sides, making the gap larger so that the carbon fiber waste can fall. Pull the handle end of the rotating handle to make the other end of the rotating handle move downward, squeezing the lifting block. With the deformation of the reset spring, the lifting block descends on the fixed block and drives the roller to descend, making the roller abut against the surface of the carbon fiber waste, so as to squeeze the carbon fiber waste through the gap to the surface of the cutting head. As the movable block slides along the length direction of the cross beam on the cross beam, the cutting of the carbon fiber waste can be completed. The overall practicability is strong, and the use is convenient. The operation can be completed with one hand, improving the work efficiency. Description of the Drawings

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] For the convenience of cutting carbon fiber waste, refer to Figure 1 , Figure 2 and Figure 3 As shown, it includes a base 1, two bearing plates 2 for placing carbon fiber waste to be cut, a cutting head 3, a stretching mechanism and a pressing mechanism. The cutting head 3 is arranged on the base 1. A gap is reserved between the two bearing plates 2. The bearing plates 2 are installed on the base 1 through the stretching mechanism, so that the gap is located directly above the cutting head 3. Among them, the pressing mechanism presses on the bearing plates 2, and the bearing plates 2 slide arc-shaped towards both sides under the elasticity of the stretching mechanism, so that the carbon fiber waste falls through the gap and abuts against the cutting head 3 to achieve cutting. The carbon fiber waste to be cut is laid flat on the surfaces of the two bearing plates 2. Rotate the rotating handle 14. Through the meshing of the gear 13 with the two saw tooth bars 11, the two saw tooth bars 11 move in opposite directions respectively, driving the two pressing plates to press on the bearing plates 2. At this time, with the deformation of the tension spring 5, the two bearing plates 2 move arc-shaped towards both sides, making the gap larger so that the carbon fiber waste can fall. Pull the handle end of the rotating handle 14, so that the other end of the rotating handle 14 moves downward, pressing on the lifting block 16. With the deformation of the reset spring 17, the lifting block 16 descends on the fixed block 15 and drives the roller 18 to descend, so that the roller 18 abuts against the surface of the carbon fiber waste, thereby squeezing the carbon fiber waste through the gap onto the surface of the cutting head 3. As the movable block 10 slides along the length direction of the cross beam 9 on the cross beam 9, the cutting of the carbon fiber waste can be completed, and the overall practicality is relatively strong.

[0022] In order to cut the carbon fiber waste along the cutting line, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the stretching mechanism includes connecting columns 4 respectively arranged on both sides of the bearing plate 2 and the base 1. A stretching spring 5 is arranged between the connecting columns 4. Pivot pins 6 are respectively arranged in the base 1 towards both sides of the bearing plate 2. The two bearing plates 2 are connected by a connecting piece 7. The surface of the connecting piece 7 is provided with kidney-shaped holes adapted to the pivot pins 6. The connecting piece 7 is clamped on the pivot pins 6 through the kidney-shaped holes to realize the deflection of the two bearing plates 2. When the two bearing plates 2 are squeezed, they rotate through the cooperation of the kidney-shaped holes and the pivot pins 6, so that the two bearing plates 2 slide arcuately towards both sides respectively, and at the same time, the stretching spring 5 deforms. After the cutting is completed, with the stretching of the stretching spring 5, the two bearing plates 2 can be reset and restored to a parallel state again. Both sides of the base 1 are provided with support frames 8, and a cross beam 9 is arranged between the two support frames 8. The pressing mechanism includes a movable block 10 arranged on the cross beam 9. By moving the movable block 10 on the cross beam 9, the movement of the roller 18 can be driven, and the carbon fiber waste can be cut along the preset cutting line. On both sides of the movable block 10, two arc-shaped saw teeth strips 11 are symmetrically arranged respectively. On the side away from each other of the two saw teeth strips 11, pressing plates 12 are arranged obliquely downward. A gear 13 for transmission is arranged between the two saw teeth strips 11. The gear 13 meshes with the two saw teeth strips 11. As the gear 13 rotates, the two saw teeth strips 11 slide in opposite directions, thereby driving the two pressing plates 12 to move downward to press the bearing plate 2. On the upper surface of the gear 13, a rotating handle 14 is arranged. The rotating handle 14 can rotate horizontally or vertically. A fixed block 15 is arranged outside the movable block 10. Chute grooves are opened on both outer sides of the fixed block 15. A lifting block 16 slides on the fixed block 15 through the chute grooves. A return spring 17 is arranged between the lifting block 16 and the fixed block 15, and the lifting block 16 is located vertically below the end of the rotating handle 14. A roller 18 is arranged on the lower surface of the lifting block 16. When the rotating handle 14 presses the lifting block 16, the return spring 17 deforms, causing the lifting block 16 to descend and making the roller 18 abut against the carbon fiber waste, so that the carbon fiber waste can be cut along the cutting line. When the rotating handle 14 is released, the return spring 17 resets and reacts on the lifting block 16, enabling the lifting block 16 to rise.

[0023] During use, first lay the carbon fiber waste to be cut flat on the surfaces of the two bearing plates 2. Rotate the rotary handle 14. Through the engagement of the gear 13 with the two saw racks 11, the two saw racks 11 move in opposite directions respectively, driving the two pressing plates to press the bearing plates 2. At this time, with the deformation of the tension spring 5, the two bearing plates 2 move arcuately towards both sides, increasing the gap so that the carbon fiber waste can fall. Pull the handle end of the rotary handle 14, causing the other end of the rotary handle 14 to move downward, squeezing the lifting block 16. With the deformation of the return spring 17, the lifting block 16 descends on the fixed block 15, driving the descent of the roller 18, making the roller 18 abut against the surface of the carbon fiber waste, thereby squeezing the carbon fiber waste through the gap onto the surface of the cutting head 3. As the movable block 10 slides along the length direction of the cross beam 9 on the cross beam 9, the cutting of the carbon fiber waste can be completed.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
