Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber production, in particular to a shearing device for carbon fiber webbing used for composite material reinforcement. Background Art

[0002] Carbon fiber reinforced composite material is a composite material composed of carbon fiber and resin and other base materials. Carbon fiber is a high-strength, high-modulus fiber material with excellent properties such as light weight, corrosion resistance, and high temperature resistance. It is one of the most advanced structural materials in the world. Resin is a polymer material that can be filled between carbon fibers to play a bonding and strengthening role; since the strength of carbon fiber reinforced composite materials is too high after preparation, it is necessary to cut the wider carbon fiber ribbon into strips before compounding with resin for subsequent processing and production.

[0003] The existing carbon fiber cutting equipment will produce angled carbon fiber debris when shearing carbon fiber webbing. The debris is mixed in the cloth. When compounded with resin, the debris will form bulges, thereby affecting the quality and appearance of the carbon fiber. In addition, the temperature of the cutter of the existing cutting device will increase after long-term cutting, which may easily cause the edge of the carbon fiber webbing to be rough or thermally damaged. Therefore, a shearing equipment for carbon fiber webbing for composite material reinforcement is needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a shearing device for carbon fiber webbing for composite material reinforcement, which has the advantages of less cutting debris and good cutting knife cooling effect, and solves the problems in the prior art of excessive debris generated during the cutting process of carbon fiber woven bags and the easy fuzzing or heat damage of the edges of the carbon fiber webbing.

[0006] The dust suction mechanism includes a dust hood, a filter box and a blower. The dust hood is located at the lower end of the cutting roller. The upper end of the dust hood is provided with a guide hood, and the guide hood is sleeved on the outer end of the cutter. The filter box is installed in the dust hood, and the blower is connected to the bottom of the dust hood.

[0007] As a preferred shearing device for carbon fiber webbing for composite material reinforcement of the utility model, the bottom of the filter box is a honeycomb hole structure, the front end surface of the dust hood is provided with a slide groove, and the filter box is inserted into the dust hood and slidably connected thereto.

[0014] 1. The utility model provides a dust suction mechanism at the lower end of the cutter, and the dust suction mechanism sucks the fiber debris generated during the shearing process into the filter box, thereby preventing the debris from being mixed in the carbon fiber webbing and affecting the quality of the final product.

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 6 A shearing device for carbon fiber webbing for composite material reinforcement includes a shearing machine body 1, on which a feeding roller 110, a cutting roller 120 and a driving roller 130 are arranged, a cutting knife 121 is arranged on the surface of the cutting roller 120, and a dust collecting mechanism 2 is arranged at the lower end of the cutting roller 120; a cooling mechanism 3 is arranged on the shearing machine body 1;

[0024] The dust suction mechanism 2 includes a dust hood 210, a filter box 220 and a blower 230. The dust hood 210 is located at the lower end of the cutting roller 120. The upper end of the dust hood 210 is provided with a guide cover 211, which is sleeved on the outer end of the cutter 121. The filter box 220 is installed in the dust hood 210, and the blower 230 is connected to the bottom of the dust hood 210.

[0025] When the device is in use, when the cutter 121 cuts the carbon fiber webbing, air is drawn through the blower 230, thereby forming a negative pressure above the air guide cover 211, and the debris generated by the cutting is sucked into the filter box 220, and at the same time, the submersible pump 320 is started, and cooling water is circulated and pumped into the water flow channel 212 through the submersible pump 320, and the cooling water is cooled and cooled by the refrigerator 330. When the cooling water flows through the air guide cover 211, the air temperature around the air guide cover 211 is rapidly reduced, thereby absorbing the heat generated by the cutter 121. At the same time, the airflow generated by the blower 230 accelerates the air flow around the cutter 121, further improving the heat dissipation effect, and preventing the cutter 121 from overheating and causing fuzzing or heat damage to the carbon fiber.

[0026] Furthermore, the bottom of the filter box 220 is a honeycomb hollow structure, and the front end surface of the dust hood 210 is provided with a slide groove 214, and the filter box 220 is inserted into the dust hood 210 and slidably connected thereto.

[0027] The debris falls into the filter box 220 and is retained by the filter box 220. After the production is completed, the filter box 220 is pulled outward, so that the debris inside it can be quickly cleaned.

[0028] Furthermore, the air guide cover 211 is a fan-shaped structure, and the bottom of the air guide cover 211 is connected to the dust collection cover 210 through.

[0029] The air inlet area is reduced by the air guide cover 211, thereby increasing the dust suction pressure, and the fan-shaped structure fits the cutter 121 more closely, thereby increasing the heat dissipation effect of the airflow on the cutter 121.

[0030] Furthermore, the cooling mechanism 3 includes a water tank 310 and a submersible pump 320 . The top of the dust cover 210 and the side wall of the air guide cover 211 are provided with a water flow channel 212 . The submersible pump 320 is connected to the water flow channel 212 through a stainless steel pipe.

[0031] The cooling water is circulated and pumped into the water flow channel 212 by the submersible pump 320 , so that the air deflector 211 is kept at a relatively low temperature, and the cutter 121 is placed in a low temperature environment, which can accelerate the heat dissipation of the cutter 121 .

[0032] Furthermore, a partition plate 213 is disposed inside the side wall of the air deflector 211 .

[0033] The water is forced to flow upward through the partition 213 to cool the air guide cover 211 , thereby preventing the cooling water from directly flowing back without passing through the side wall of the air guide cover 211 .

[0034] Furthermore, a refrigerator 330 is disposed in the water tank 310 .

[0035] The coolant in the water tank 310 is cooled by the refrigerator 330 , thereby further improving the heat dissipation effect of the cutter 121 .

[0036] Furthermore, the dust hood 210 is made of aluminum alloy.

[0037] Aluminum alloy has good thermal conductivity and corrosion resistance, which improves the heat dissipation effect while ensuring the service life of the equipment.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
