[0029] Referring to Figures 1 to 4 The embodiment of the present application provides a laser cutting machine, which comprises a base 100, a laser head 200 and a blanking device 300.

[0030] Referring to Figure 1 It can be understood that the upper end of the base 100 is provided with an input roller 110 and an output roller 120, the input roller 110 and the output roller 120 are parallel and arranged in the left-right direction, and the input roller 110 and the output roller 120 are arranged in the front-rear direction, the input roller 110 and the output roller 120 are located on the same horizontal plane, the plane where the upper ends of the input roller 110 and the output roller 120 are located is a conveying plane, and the input roller 110 and the output roller 120 rotate by driving a motor to realize conveying of the plate, and the conveying direction is defined as from left to right.

[0031] Referring to Figure 1 It can be understood that the base 100 is also provided with a blanking hopper 130, the blanking hopper 130 is funnel-shaped, the blanking hopper 130 penetrates in the up-down direction, and the blanking hopper 130 is located between the input roller 110 and the output roller 120, so as to guide the workpiece to the product box.

[0032] Referring toFigure 1 As shown, it can be understood that the laser head 200 is movably installed on the base 100 and located above the conveying plane. It can be easily understood that the laser head 200 can move in the left-right direction, the front-rear direction and the up-down direction to cut workpieces of different shapes on the plate. The mounting structure of the laser head 200 is well known to those skilled in the art, which will not be described here.

[0033] Referring to Figure 1 and Figure 2 As shown, it can be understood that the blanking device 300 is arranged at the output end of the output roller 120, that is, the blanking device 300 is located at the right side of the base 100. The blanking device 300 includes a rack 310 and two conveying mechanisms 320. Specifically, the rack 310 is a frame structure with a hollow middle part. The conveying direction of the conveying mechanism 320 is the same as the conveying direction of the output roller 120, that is, the conveying direction of the conveying mechanism 320 is also from left to right. The two conveying mechanisms 320 are slidably installed on the upper end of the rack 310 along the axial direction of the output roller 120, that is, the conveying mechanism 320 can slide in the front-rear direction. The two conveying mechanisms 320 are symmetrically arranged in the front-rear direction, and a blanking passage 330 for outputting plate waste is arranged between the two conveying mechanisms 320. The two conveying mechanisms 320 are respectively connected with driving members 340, which can be air cylinders or hydraulic cylinders, so that the two driving members 340 can drive the two conveying mechanisms 320 to move towards or away from each other.

[0034] Referring to Figure 2 As shown, it can be understood that generally, the plate waste has a large width and is easy to deform. When the plate waste is conveyed onto the two conveying mechanisms 320 and the conveying mechanisms 320 convey the plate waste into position, the front and rear sides of the plate waste are respectively supported on the two conveying mechanisms 320, and the middle part of the plate waste is suspended. Under the action of gravity, the middle part of the plate waste is depressed downward, and the front and rear sides of the plate waste are slightly raised upward. Therefore, when the two conveying mechanisms 320 move away from each other, the plate waste will not move with the conveying mechanisms 320, until the front and rear sides of the plate waste are separated from the two conveying mechanisms 320, and the plate waste falls into the blanking passage 330, realizing automatic cleaning of waste without manual picking up, which is safe and reliable.

[0035] By setting the discharging device 300 at the output end of the output roller 120, the discharging device 300 comprises two conveying mechanisms 320 capable of moving towards or away from each other, thus the plate waste on the conveying plane between the input roller 110 and the output roller 120 can be conveyed to the two conveying mechanisms 320, the driving member 340 drives the two conveying mechanisms 320 to move away from each other and open, so that the plate waste is separated from the two conveying mechanisms 320 and falls into the discharging channel 330, realizing automatic cleaning of waste, without manual picking, safe and reliable, and without interfering with the movement of the laser head 200, the laser head 200 and the discharging device 300 can act simultaneously, which is conducive to improving the production efficiency.

[0036] Referring to Figure 1 It can be understood that the upper end of the two conveying mechanisms 320 is a conveying plane, and the upper end of the output roller 120 is higher than the conveying plane, so that when the output roller 120 outputs the plate waste, the plate waste is slightly higher than the conveying plane, and under the action of gravity, the plate waste can fall into the upper end of the conveying mechanism 320, avoiding the plate waste being stuck during conveying and improving the reliability.

[0037] Referring to Figure 1 and Figure 2 It can be understood that the rack 310 is provided with a material detector 311, the material detector 311 is an optical switch, the material detector 311 is installed at the right end of the rack 310 and above the conveying plane, the detection end of the material detector 311 faces, and the material detector 311 is signal connected with the driving member 340 through a controller (such as a control system). The material detector 311 can detect whether the plate waste is conveyed in place, and after the plate waste is conveyed in place, the controller transmits a start signal to the driving member 340, so as to discharge the material, which is convenient for control.

[0038] Referring to Figure 4As shown, it can be understood that the conveying mechanism 320 comprises a sliding frame 321, a conveying belt 322 and a plurality of support seats 323, the sliding frame 321 is slidingly installed on the rack 310 in the front-rear direction, the left and right ends of the sliding frame 321 are respectively provided with conveying wheels 3213, the center line direction of the conveying wheels 3213 is the same as the center line direction of the output roller 120, the two conveying wheels 3213 are connected through a conveying chain, one of the conveying wheels 3213 is connected with a motor, so that the two conveying wheels 3213 can be driven to rotate at the same time. The plurality of support seats 323 are installed on the upper end of the sliding frame 321 in the left-right direction and are located between the two conveying wheels 3213, the lower end of the support seat 323 is provided with a hollow part 3231, the conveying belt 322 is wound around the two conveying wheels 3213, and the lower part of the conveying belt 322 passes through the hollow part 3231, and the upper part of the conveying belt 322 is carried on the upper end surface of the support seat 323, so that the support seat 323 neither affects the rotation of the conveying belt 322 driven by the conveying wheels 3213, nor provides support for the conveying belt 322, so as to convey the plate waste, which is simple in structure and easy to realize.

[0039] Next, the conveying mechanism 320 located at the front side will be further described.

When the two conveying mechanisms 320 move away and move a certain distance, the first stop block 3211 abuts against the first buffer 312, which on the one hand provides a buffering effect for the conveying mechanism 320 in one direction, avoids hard collision of the conveying mechanism 320, and on the other hand can limit the movement of the conveying mechanism 320 when moving away, avoids the conveying mechanism 320 from leaving the rack 310, and improves the reliability.

When the two conveying mechanisms 320 move towards each other and move a certain distance, the second stopper 314 abuts against the second buffer 3212, which, on the one hand, provides a buffering effect on the conveying mechanism 320 in the opposite direction, avoiding hard collision of the conveying mechanism 320, and on the other hand, can limit the conveying mechanism 320 when moving towards each other, avoiding the conveying mechanism 320 from leaving the rack 310, improving the reliability. In combination with the first stopper 3211 and the first buffer 312, the movement stroke of the conveying mechanism 320 in the front-rear direction can be limited, further improving the reliability.

[0042] With reference to Figure 3 As shown, it can be understood that the front end of the rack 310 is further provided with a first sensing switch 313 and a second sensing switch 315, the first sensing switch 313 is located at one side of the first buffer 312, and the second sensing switch 315 is located at one side of the second stopper 314. Generally, the first sensing switch 313 and the second sensing switch 315 are both signal-connected with the controller. The first sensing switch 313 has a first sensing end, when the first buffer 312 abuts against the first stopper 3211, the first sensing end faces the first stopper 3211, and the first sensing switch 313 sends a first arrival signal to the controller, so that the controller can control the driver to stop working according to the first arrival signal. Similarly, the second sensing switch 315 has a second sensing end, when the second buffer 3212 abuts against the second stopper 314, the second sensing end faces the second buffer 3212, and the second sensing switch 315 sends a second arrival signal to the controller, so that the controller can control the driver to stop working according to the second arrival signal. Therefore, sensing signals are arranged at both ends of the stroke range of the conveying mechanism 320, so as to control the driver to work.

[0043] With reference to Figure 2 As shown, it can be understood that the discharging device 300 further comprises a material collecting box 350 located at the lower end of the discharging channel, so that the board waste falls into the material collecting box 350, facilitating cleaning. The bottom of the material collecting box 350 is provided with a roller 351, facilitating workers to push the material collecting box 350 to remove the board waste.

[0044] With reference to Figure 2As shown, it can be understood that the rack 310 is provided with a guide groove 316 fixedly installed at the bottom of the rack 310, and generally, the guide groove 316 is installed on the ground. The guide groove 316 is arranged along the front-rear direction and the slot is upward, that is, the guide direction of the guide groove 316 is the front-rear direction, and the lower end of the material collecting box 350 is further provided with a plurality of positioning wheels 352, which are arranged along the front-rear direction at intervals, the center line of the positioning wheel 352 is arranged along the up-down direction, the positioning wheel 352 is accommodated in the guide groove 316 and can roll along the guide groove 316, so that the material collecting box 350 can be positioned along the left-right direction, so that the material collecting box 350 can be aligned with the discharging channel 330, so that the wood waste can accurately fall into the material collecting box 350, and the cleaning is facilitated.
