When the starting end of the steel strip contacts the delay switch 1063, the electric telescopic rod 1061 contracts to drive the connecting plate 1062 to return to the cavity 106. At the same time, the delay switch 1063 controls the motor A1014, the motor B1041 and the motor C1051 to stop working, and the electric cylinder 1021 contracts to make the laser cutting head 1031 Contacting with the upper surface of the steel strip, the screw slide rail 103 and the laser cutting head 1031 work to cut off the steel strip, and then the motor C1051 and the motor A1014 close to the motor C1051 work to drive the corresponding limiting roller B105 and the conveying roller B1013 to rotate, clamping the cut steel strip to move, and after the cut steel strip is unloaded from the through groove, the electric telescopic rod 1061 continues to extend, driving the connecting plate 1062 to move downward, and continuing the above work to cut the next section of the steel strip, and repeating the cycle.

[0031] Reference Figure 1 , 3In this embodiment, one side of the support frame 1 is rotatably connected with a screw rod B204 through a groove embedding, one side of the support frame 1 is installed with a servo motor B2041, and the output shaft of the servo motor B2041 is connected to the screw rod B204, one side of the support frame 1 is fixedly installed with a guide rod 205 through a groove embedding, and the guide rod 205 is parallel to the screw rod B204, one side of the support frame 1 is slidably connected with a discharge rack 2, and the discharge rack 2 is L-shaped, and the bottom of the discharge rack 2 is nested and slidably connected to the outside of the screw rod B204 and the guide rod 205, and the discharge rack 2 is threadedly connected to the screw rod B204, and the number of the discharge racks 2 is two;

[0032] The servo motor B2041 drives the screw rod B204 to rotate, driving the two unloading racks 2 to move along the guide rod 205 until one unloading rack 2 is opposite to the through slot outlet, and the steel belts removed from the through slot outlet are stacked and collected above the corresponding unloading rack 2. When the steel belts above the unloading rack 2 are full, the servo motor B2041 drives the screw rod B204 to rotate in the opposite direction, so that the other unloading rack 2 is opposite to the through slot outlet. The two unloading racks 2 work alternately, making the unloading work more continuous.

[0033] Reference Figure 1-3 In this embodiment, one side of the unloading frame 2 is symmetrically connected to the screw rod A201 through the servo motor A2011, and a support plate B202 is provided above the unloading frame 2. A connecting block 2021 is fixedly installed on one side of the support plate B202, and the connecting block 2021 is nested and threadedly connected to the outside of the two screw rods A201.

[0034] The servo motor A2011 drives the screw rod A201 to rotate, so that the support plate B202 moves up and is flush with the upper edge of the support plate A101. According to the length of the cut steel strip, the telescopic length of the servo electric cylinder B2031 is adjusted to move the limit slot 203 to a suitable position, and the steel strip moved out of the through slot outlet moves to the top of the support plate B202. Then the servo motor A2011 drives the screw rod A201 to rotate slightly in the opposite direction, so that the support plate B202 moves down a distance, and the second steel strip is stacked on top of the first steel strip. This reciprocating process stacks the cut steel strips in the limit slot 203 above the support plate B202 in turn. The servo electric cylinder B2031 continues to extend, pushing the limit slot 203 to move, and pushing the steel strip above the support plate B202 to other support panels. The roller 2022 reduces the friction between the steel strip and the support plate B202, making it easier to unload the steel strip.

[0036] Working principle: First, according to the required length of the steel belt, the electric telescopic rod 1061 at the corresponding position is extended to push the corresponding connecting plate 1062 down to the through slot. The servo motor B2041 drives the screw rod B204 to rotate, driving the two unloading racks 2 to move along the guide rod 205 until one unloading rack 2 is directly opposite to the through slot exit. The servo motor A2011 drives the screw rod A201 to rotate, so that the support plate B202 moves up and is flush with the upper edge of the support plate A101. According to the length of the cut steel belt, the telescopic length of the servo electric cylinder B2031 is adjusted to move the limit slot 203 to a suitable position. Then the staff inserts the starting end of the steel belt into the through slot on one side of the support frame 1. The servo electric cylinder A1011 extends to push the support plate A101. The steel belt is moved upward, so that the limit roller A104 and the conveying roller A1012 are clamped on the upper and lower sides of the steel belt respectively, and the motor A1014 and the motor B1041 close to the limit roller A104 work to drive the corresponding conveying roller A1012 and the limit roller A104 to rotate, and the limit roller A104 and the conveying roller A1012 clamp the steel belt and move slowly to convey the steel belt until the starting end of the steel belt enters from another through groove, and the other motor A1014 and the motor C1051 work to drive the corresponding conveying roller B1013 and the limit roller B105 to rotate, clamping the steel belt to move, and when the starting end of the steel belt contacts the delay switch 1063, the electric telescopic rod 1061 contracts to drive the connecting plate 1062 to return to the inside of the cavity 106, and the delay switch 1063 The two motors A1014, B1041 and C1051 are controlled to stop working, the electric cylinder 1021 contracts, and the cross frame 102 is driven to move downward, so that the laser cutting head 1031 contacts the upper surface of the steel strip, and the laser cutting head 1031 works to cut the steel strip. The screw slide rail 103 cooperates to drive the laser cutting head 1031 to move, cut the steel strip, and complete the cutting of the steel strip. During the cutting process, the conveying roller B1013 and the limiting roller B105 clamp and fix one side of the steel strip, and the conveying roller A1012 and the limiting roller A104 clamp and fix the other side of the steel strip to avoid the warping of the steel strip during the cutting process and affect the cutting effect. The pressure plate 1033 is always pressed on the cutting position of the steel strip under the action of the spring telescopic rod, and the pressure plate 1033 moves with As the laser cutting head 1031 moves, the ball 1034 reduces the friction between the pressure plate 1033 and the steel strip. The pressure plate 1033 flattens the edge of the steel strip cut, allowing it to smoothly enter another through slot later. Then the electric cylinder 1021 extends to push the laser cutting head 1031 away from the steel strip. The motor C1051 and the motor A1014 close to the motor C1051 work, driving the corresponding limit roller B105 and the conveying roller B1013 to rotate, clamping the cut steel strip and moving it. After the cut steel strip is unloaded from the through slot, the electric telescopic rod 1061 continues to extend, driving the connecting plate 1062 to move downward, continuing the above work, cutting the next section of the steel strip, and repeating the cycle. Finally, the steel strip removed from the through slot outlet moves to the top of the support plate B202.After that, the servo motor A2011 drives the screw rod A201 to rotate slightly in the opposite direction, so that the support plate B202 moves down a certain distance, and the second steel strip is stacked on top of the first steel strip. This process is repeated, and the cut steel strips are stacked in sequence in the limit slot 203 above the support plate B202. When the steel strips above the unloading rack 2 are full, the servo motor B2041 drives the screw rod B204 to rotate in the opposite direction, so that another unloading rack 2 is directly opposite to the through slot outlet, and the cut steel strips are continuously collected and unloaded. The servo electric cylinder B2031 above the idle unloading rack 2 continues to extend, pushing the limit slot 203 to move, and pushing the steel strips above the support plate B202 to other support panels. The roller 2022 reduces the friction between the steel strip and the support plate B202, making it easier to unload the steel strips.
