Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced plastic processing, in particular to a shearing device and a shearing method for processing glass fiber reinforced plastic materials. Background Art

[0002] FRP, or fiber reinforced plastic, generally refers to reinforced plastics that use glass fibers to reinforce unsaturated polyester, epoxy resin and phenolic resin matrices, with glass fibers or their products as reinforcing materials. They are called glass fiber reinforced plastics, or FRP.

[0003] For example, a shearing device for glass fiber reinforced plastic processing with announcement number CN217414110U relates to the technical field of glass fiber reinforced plastic processing. The shearing device for glass fiber reinforced plastic processing comprises a base plate and a workbench installed on its upper surface, the upper surface of the workbench is provided with a first mounting groove, the bottom of the workbench is provided with a second mounting groove interconnected with the first mounting groove, the interiors of the first mounting groove and the second mounting groove are both slidably connected with a collecting mechanism for collecting debris generated by cutting glass fiber, the discharge port of the collecting mechanism is slidably connected with a connecting sleeve, and the first mounting groove and the second mounting groove are provided on the upper surface and the bottom of the workbench. The collecting mechanism is installed in the groove, and a sliding connection connecting sleeve is arranged at the discharge port of the collecting mechanism, which not only makes it convenient for the user to install and disassemble the storage box by sliding the connecting sleeve, but also prevents the debris from splashing during the material guiding process of the collecting mechanism, thereby achieving the purpose of facilitating collection. However, the device does not provide protection around the cutting knife. During the shearing process, a small amount of glass fiber debris may still splash around, which is not convenient for collecting the debris well and brings trouble to subsequent cleaning. At the same time, the glass fiber will also produce smaller glass fiber dust when cutting. When these smaller dusts are inhaled into the human respiratory system, they will also cause harm to human health.

An extraction mechanism is provided. When the shearing knife contacts the cutting position of the FRP material, the linear motor is started to move. The linear motor drives the knife holder and the shearing knife to reciprocate, thereby shearing the FRP material. At the same time, the linear motor drives the gears on both sides to move. The gears are meshed with the racks to rotate, and the gears drive the rotating shaft and the fan blades to rotate.

The T-shaped plate continues to press down to compress the spring until the front and rear mounting plates of the linear motor contact the FRP material. The front and rear mounting plates of the linear motor and the side pressure plates on both sides are close to each other and fit together to form a circle, thereby preventing the shearing knife from splashing when shearing. Most of the debris falls through the mesh plate and the drop port, and falls into the collection trough after being guided by the guide trough for collection. A small amount of smaller debris and glass fiber dust are extracted and processed by the extraction mechanism, which improves the processing effect of the debris. 3.

An extraction hose 87 is connected to one side of the top of the air collecting box 86, and an exhaust pipe 810 is connected to the other side of the top of the air collecting box 86. A one-way valve 88 is installed on the side of the extraction hose 87 close to the air collecting box 86, and an extraction hood 89 is installed on the end of the one-way valve 88 away from the air collecting box 86 through the side pressure plate 74, and a one-way valve 2 811 is installed on the side of the exhaust pipe 810 close to the air collecting box 86.

[0034] Embodiment 3: Figure 7-Figure 11 As shown, an extraction mechanism 8 is provided. When the shearing knife 78 abuts against the cutting position of the FRP material 6, the linear motor 76 is started to move. The linear motor 76 drives the tool holder 77 and the shearing knife 78 to reciprocate, thereby performing a shearing operation on the FRP material 6. At the same time, the linear motor 76 drives the gears 81 on both sides to move. The gear 81 is meshed with the rack 82 to rotate the gear 81. The gear 81 then drives the rotating shaft 83 and the fan blade 85 to rotate. The rotating shaft 83 slides inside the slide groove 84 to assist the movement of the linear motor 76 and the shearing knife 78.

[0035] When the linear motor 76 moves forward, the rack 82 rotates so that the interior of the air collecting box 86 is under negative pressure, and the one-way valve 1 88 is connected and the one-way valve 2 811 is closed, so that air is extracted through the extraction hose 87 and the extraction cover 89, and the extracted gas is temporarily stored in the air collecting box 86. When the linear motor 76 moves backward, the rack 82 rotates to blow air to the air collecting box 86, the one-way valve 1 88 is closed and the one-way valve 2 811 is connected, and then the gas and glass fiber dust temporarily stored in the air collecting box 86 are transported to the collection box 812 through the exhaust pipe 810 for storage. Combined with the sealing of the clamping mechanism 7, the splashing of debris and the harm of dust during the shearing of the fiberglass material 6 are reduced, the shear protection effect of the device is improved, and the problem that there may still be a small amount of glass fiber debris splashing around during the shearing process and small glass fiber dust generated during cutting, which may also cause harm to human health, is solved.

[0036] Working principle: When using the device, first, Figure 1-Figure 11 As shown, the glass fiber reinforced plastic material 6 is placed in the middle of the top of the horizontal plate 3, and the disc 16 is pulled, and the disc 16 drives the pin 17 to disengage from the limiting hole 15, thereby releasing the limit on the turntable 13, and then the turntable 13 is rotated, and the turntable 13 drives the screw rod 12 to rotate, and the guide rod 18 and the sliding sleeve 20 play a limiting role, so that the threaded sleeve 19 drives the lower plate 21 to move laterally, thereby facilitating the adjustment of the shearing position. After adjustment, the disc 16 is pressed, and the disc 16 drives the pin 17 to snap into the limiting hole 15, which is convenient for limiting the turntable 13 again, reducing displacement during shearing and improving shearing accuracy.

[0037] By starting the electric push rod 22, the electric push rod 22 drives the moving plate 71 to descend, and the moving plate 71 drives the T-shaped plates 72 on both sides to descend. The T-shaped plates 72 drive the side pressure plates 74 to press down through the sliding rods 73. The moving plate 71 also drives the bottom knife holder 77 and the shear knife 78 to press down. The shear knife 78 first contacts the glass fiber reinforced plastic material 6, and the side pressure plates 74 contact the glass fiber reinforced plastic material 6. Then the electric push rod 22 continues to drive the moving plate 71 to press down. The T-shaped plate 72 continues to press down to compress the spring 75 until the front and rear mounting plates of the linear motor 76 contact the glass fiber reinforced plastic material 6. The front and rear mounting plates of the linear motor 76 are close to and fit with the side pressure plates 74 on both sides to form a circle, thereby preventing splashing when the shear knife 78 shears. Most of the debris falls through the mesh plate 9 and the blanking port 23, and is guided by the guide trough 10 and then falls into the collecting trough 11 for collection. A small amount of smaller debris and glass fiber dust is extracted and processed by the extraction mechanism 8.

[0038] When the shearing knife 78 contacts the cutting position of the FRP material 6, the linear motor 76 is started to move, and the linear motor 76 drives the tool holder 77 and the shearing knife 78 to reciprocate, thereby shearing the FRP material 6. At the same time, the linear motor 76 drives the gears 81 on both sides to move, and the gear 81 is meshed with the rack 82 to make the gear 81 rotate, and the gear 81 then drives the rotating shaft 83 and the fan blade 85 to rotate, and the rotating shaft 83 slides inside the slide groove 84 to assist the movement of the linear motor 76 and the shearing knife 78.
