The profiling assembly is installed on the dual-channel frame 4. When the profiling assembly is in operation, the profiling assembly can press the steel fiber into a required shape.

[0028] See also Figure 4 and Figure 5As shown, the pressing assembly includes a fixing frame 15, a lifting plate 151, a corrugated plate 152, a fixing rod 153, a driving assembly and a fixing assembly. A fixing frame 15 is fixedly connected between the left sides of the front and rear sides of the double-channel frame 4. A lifting plate 151 is slidably mounted on the fixing frame 15. The bottom of the lifting plate 151 is symmetrically fixed with a corrugated plate 152.

A molding strip is arranged on the left side of the double-channel frame 4. The molding strip of the double-channel frame 4 corresponds to the molding groove on the corrugated plate 152. When the corrugated plate 152 moves downward and contacts the steel fiber, the molding strip on the corrugated plate 152 The groove cooperates with the forming strip of the double-channel frame 4 to press the steel fiber into the required shape. A fixing component is arranged on the profiled plate 152. When the fixing component is in operation, the fixing component can press and fix the steel fiber during the cutting process. A fixing rod 153 is symmetrically fixed to the top of the lifting plate 151. A driving component is arranged between the fixing rod 153 and the double-channel frame 4.

The left sides of the front and rear sides of the double-channel frame 4 are rotatably connected to the turntable 154. The eccentric positions of the two sides of the disks 154 that are away from each other are rotatably connected with connecting rods 155, and the tail ends of the connecting rods 155 on the front and rear sides are rotatably connected with the ends of the fixed rods 153 on the front and rear sides respectively. A fixed plate 156 is symmetrically fixed to the left and front sides of the top of the workbench 1. The fixed plate 156 is located on the right side of the support plate 22. A spur gear 157 is rotatably connected to the fixed plate 156. The shaft of the spur gear 157 is connected to the shaft of the turntable 154 through a synchronous belt assembly. The outer side surfaces of the front and rear disks 11 are fixed with arc-shaped racks 158, which rotate and mesh with the spur gear 157, and the arc-shaped racks 158 correspond to the blades of the cutting cylinder 2; the fixed assembly includes a guide plate 159, a movable Rod 1510, pressure plate 1511 and connecting spring 1512, guide plates 159 are fixedly connected to the left side of the top of the front and rear corrugated plates 152, and movable rods 1510 are symmetrically slidably connected to the left side of the front and rear guide plates 159. A pressure plate 1511 is fixedly connected between the bottom ends of the two movable rods 1510 on each guide plate 159. The height of the pressure plate 1511 is lower than the corrugated plate 152. When the pressure plate 1511 moves downward and contacts the steel fiber, the pressure plate 1511 can press and fix the steel fiber. A connecting spring 1512 is symmetrically connected between the top of the pressure plate 1511 and the left side of the bottom of the guide plate 159, and the connecting spring 1512 is sleeved on the movable rod 1510.

[0029] First, the steel fiber raw materials of two different materials are moved into the double-channel frame 4 respectively, and the ends of the raw materials are passed through the upper and lower conveying rollers 6 and are flush with the left side of the double-channel frame 4, and then the screw rod 14 is twisted and rotated. The screw rod 14 rotates to adjust the distance between the slide rod 13 and the center of the disc 11, and the lateral movement distance of the driving rod 10 is adjusted. The adjustment of the lateral movement distance of the driving rod 10 is to adjust the swing angle of the swing rod 9, thereby adjusting the rotation angle of the conveying roller 6. The adjustment of the rotation angle of the conveying roller 6 is to adjust the feeding distance of the raw materials, and thus the width of the steel fiber cutting is adjusted. In this way, the width of the steel fiber cutting on the front and rear sides can be adjusted separately by twisting the front and rear screw rods 14. When the steel fiber cutting on the front and rear sides is When the width is adjusted to the required width, stop twisting the screw 14, and then start the drive motor 21 to rotate forward. The drive motor 21 rotates forward through the synchronous belt assembly to drive the cutting cylinder 2 to rotate forward. The cutting cylinder 2 rotates forward to drive the disc 11 to rotate forward. The disc 11 rotates forward to drive the arc rack 158 and the return block 12 to rotate forward. The return block 12 rotates forward to drive the slide bar 13 to rotate forward. The slide bar 13 rotates forward through the drive rod 10 to drive the swing rod 9 to swing left and right. The maximum swing angle of the swing rod 9 is less than 180 degrees. The swing rod 9 swings to the right to drive the one-way clutch 8 to rotate forward. The one-way clutch 8 rotates forward to drive the upper conveying roller 6 to rotate forward. The upper conveying roller 6 rotates forward through the gear group to drive the lower conveying roller 6 to reverse. The upper conveying roller 6 rotates forward and the lower conveying roller 6 rotates reversely to drive the raw material to move to the left. When the swing arm 9 swings to the left, due to the action of the one-way clutch 8, the swing arm 9 swings to the left and drives the one-way clutch 8 to reverse and idle, the upper conveying roller 6 and the lower conveying roller 6 also stop rotating, and the raw material stops moving to the left, and then the arc rack 158 rotates forward and engages with the spur gear 157, the arc rack 158 drives the spur gear 157 to reverse, the spur gear 157 reverses and drives the turntable 154 to reverse through the synchronous belt assembly, the turntable 154 reverses and drives the connecting rod 155 to move downward, the connecting rod 155 drives the fixed rod 153 to move downward, the fixed rod 153 moves downward and drives the lifting plate 151 to move downward, the lifting plate 151 drives the profiled plate 152 to move downward, the profiled plate 152 drives the guide plate 159 to move downward, the guide plate 159 is connected The spring 1512 drives the pressing plate 1511 to move downward, and the pressing plate 1511 moves downward to contact the raw material. The pressing plate 1511 presses and fixes the raw material, and the pressing plate 1511 stops moving downward, so that the raw material can be prevented from warping during the cutting process, causing deformation and affecting the cutting accuracy, thereby ensuring the cutting accuracy of the raw material. The guide plate 159 continues to move downward to compress the connecting spring 1512, and then the pressing plate 152 continues to move downward. The pressing plate 152 cooperates with the forming strip of the double-channel frame 4 through the forming groove to press the raw material into the required shape. At the same time, the cutting cylinder 2 rotates forward to cut the raw material that is pressed and fixed on the front and rear sides, so that the raw material is cut into steel fibers. The cut steel fibers fall downward into the discharge frame 3 and mix together to form composite steel fibers.The composite steel fiber is then discharged from the discharge frame 3 for collection. In this way, the rotation of the cutting cylinder can make the raw materials on the front and rear sides reach the required feeding distance respectively. After the raw materials are cut, the turntable 154 reverses and drives the connecting rod 155 to move upward and reset. The connecting rod 155 drives the lifting plate 151 to move upward and reset through the fixed rod 153. The lifting plate 151 drives the corrugated plate 152 to move upward and reset. The corrugated plate 152 drives the guide plate 159 to move upward and reset. The guide plate 159 first resets the connecting spring 1512, and the guide plate 159 drives the pressing plate 1511 to move upward and reset through the connecting spring 1512. The pressing plate 1511 resets and disengages from the raw material. At the same time, the arc rack 158 disengages from the spur gear 157, and the spur gear 157 stops reversing. When the cutting cylinder 2 continues to rotate forward, the raw material can be continuously pressed into the required shape and then cut to the required width by the cutting cylinder 2. In this way, the requirements of different widths can be met, thereby improving adaptability. When the steel fibers cut from the two raw materials reach the required ratio, the drive motor 21 is turned off, the cutting cylinder 2 stops rotating forward, and the disc 11 stops driving the arc-shaped rack 158 and the return block 12 to rotate forward, and the composite steel fiber can be used later.

[0030] See also Figure 6 and Figure 7 As shown, the composite steel fiber cutting and separating device also includes a limit assembly installed between the fixed frame 15 and the corrugated plate 152, the limit assembly includes a nozzle 16, a guide pipe 161 and an air supply assembly, the front and rear corrugated plates 152 are both symmetrically fixed with nozzles 16, the air outlet end of the nozzle 16 is at the bottom, the guide pipe 161 is connected between the top ends of the nozzles 16 corresponding to the front and rear sides, and an air supply assembly is arranged between the lifting plate 151 and the fixed frame 15. When the air supply assembly is in operation, the air supply assembly can discharge air into the guide pipe 16 1; the air supply assembly includes a first one-way hose 162, a cylinder 163, a piston rod 164 and a second one-way hose 165. The cylinder 163 is installed in the middle of the top of the lifting plate 151. The second one-way hose 165 is connected to the lower front part of the cylinder 163. The first one-way hose 162 is symmetrically connected to the lower part of the cylinder 163. The tail ends of the first one-way hoses 162 on the left and right sides are respectively connected to the guide pipes 161 on the left and right sides. The piston rod 164 is slidably connected to the inner side of the cylinder 163, and the top of the piston rod 164 is fixedly connected to the middle of the fixed frame 15.

[0031] When the lifting plate 151 moves downward and drives the profile plate 152 to move downward, the lifting plate 151 drives the cylinder 163 to move downward. As the cylinder 163 moves downward, the piston rod 164 draws air into the cylinder 163 through the second one-way hose 165. At the same time, the profile plate 152 moves downward and drives the nozzle 16 to move downward. Then, the profile plate 152 continues to move downward to press the raw material into the required shape. When the lifting plate 151 moves upward and drives the profile plate 152 to move upward, the lifting plate 151 drives the nozzle 16 to move downward. The cylinder 163 moves upward, and the piston rod 164 pushes the air in the cylinder 163 moving upward into the first one-way hose 162, and the air in the first one-way hose 162 is discharged into the guide tube 161, and the air in the guide tube 161 is discharged into the nozzle 16, and the nozzle 16 sprays air at high speed onto the raw material, and the pressure of the air presses the raw material, so that the raw material is stationary and out of contact with the upwardly moving profile plate 152, and the upward movement of the profile plate 152 drives the nozzle 16 to move upward and reset. In this way, the raw material pressed into the required shape can be prevented from being stuck with the profile plate 152 and being lifted up to affect the subsequent movement and cutting, thereby ensuring that the raw material moves smoothly to the left and is cut.

[0032] See also Figure 8 As shown, the composite steel fiber cutting and separating device also includes an air blowing pipe 17, and the air blowing pipe 17 is fixedly connected to the upper part of the discharge frame 3, and the air outlet end of the air blowing pipe 17 faces the cutting cylinder 2. The air blowing pipe 17 can spray air to remove the debris attached to the cutting cylinder 2.

[0033] Initially, the air blowing pipe 17 is connected to an external air pump. When the cutting cylinder 2 rotates forward to cut the steel fibers, the external air pump is started to discharge air into the air blowing pipe 17. The air blowing pipe 17 sprays air on the cutting cylinder 2. The air blows away the steel fibers attached to the outer wall of the cutting cylinder 2. The blown away steel fibers fall downward into the discharge frame 3, and the steel fibers are discharged through the discharge frame 3. When the cutting cylinder 2 stops rotating forward, the external air pump is turned off, and the air blowing pipe 17 stops spraying air. In this way, it can prevent the steel fibers from being attached to the cutting cylinder 2, which requires manual removal later, thereby ensuring that the steel fibers are completely collected and used.
