[0002] After the existing cardboard is cut on a cardboard laser cutting machine, it is usually necessary for workers to remove the waste on the cardboard, and then remove the cut finished product from the cardboard (the finished product is rectangular, and there are several holes laser-cut in the rectangle, and the cardboard in the holes is the waste). This process is rather cumbersome, reducing production efficiency and increasing labor costs.

[0025] It further includes a guiding strip 20502; the guiding strip 20502 is arranged on the second fixing plate 205; since both the upper side and the lower side of the guiding strip 20502 are inclined, the waste material 11 remaining between the first fixing plate 203 and the second fixing plate 205 is guided, so as to prevent the remaining waste material 11 from being ejected from the space formed by the first fixing plate 203 and the second fixing plate 205 when the blocking plate 207 blocks the openings at the lower sides of the first fixing plate 203 and the second fixing plate 205.

[0027] In order to protect the finished products on the cardboard 10 from being scratched by the top rod 306, the top rod 306 is made of rubber material.

[0028] It should be noted that: a vision sensor is installed on the first fixing plate 203, the air jet pipe 304 is communicated with an air pump, and a suction pump is communicated with each of the first suction groove 20302 and the second suction groove 20303 on the first fixing plate 203.

[0029] After the existing cardboard 10 is cut on a cardboard 10 laser cutting machine, it is usually necessary for workers to remove the waste 11 on the cardboard 10, and then remove the cut finished product from the cardboard 10 (the finished product is rectangular, and several holes are laser cut in the rectangle, and the cardboard 10 in the holes is the waste 11). This process is rather cumbersome, reducing production efficiency and increasing labor costs. In addition, when the workers separate the waste 11 and the finished product on the cardboard 10, since the waste 11 is tightly combined with the edge of the finished product, the edge of the finished product is damaged, thus affecting the quality of the finished product.

[0030] First, the robotic arm places the cardboard 10 on the conveyor belt 3 on the paper product cutting machine 1, and the front end of the cardboard 10 will be located on the telescopic support plate 102 on the conveyor belt 3. Then, the laser module 2 on the paper product cutting machine 1 performs laser cutting on the cardboard 10. When the laser module 2 performs laser cutting on the cardboard 10, the conveyor belt 3 will be in a stationary state. After the cardboard 10 is laser cut, the conveyor belt 3 will continue to transport forward. During this process, the convex block 10202 on the telescopic support plate 102 will contact the extrusion block 101 on the paper product cutting machine 1. When the conveyor belt 3 continues to transport forward, the convex block 10202 will be extruded by the extrusion block 101, as Figure 3As shown, the moving plate 10201 on the telescopic support plate 102 is driven to move downward along the limiting rod 103 on the telescopic support plate 102, and at the same time, the spring 104 on the telescopic support plate 102 is compressed. It should be noted that when the spring 104 is in its original length state, the upper end of the limiting hole 10203 on the moving plate 10201 is higher than the upper end of the limiting rod 103. Therefore, when the spring 104 is compressed, the moving plate 10201 will move downward along the limiting rod 103, thus preventing the moving plate 10201 from shifting and causing the cardboard 10 to shift; during the downward movement of the moving plate 10201, the first electric push rod 105 and the second electric push rod 109 will drive the transition plate 106, the receiving rod 107 and the connecting strip 108 to move downward, making the transition plate 106, the receiving rod 107 and the connecting strip 108 lower than the cardboard 10. In order to prevent the telescopic support plate 102 from affecting the downward movement of the transition plate 106, the receiving rod 107 and the connecting strip 108, therefore, through the downward movement of the moving plate 10201, it is prevented that the moving plate 10201 affects the downward movement of the transition plate 106, the receiving rod 107 and the connecting strip 108, so that the transition plate 106 and the receiving rod 107 can successfully receive the cardboard 10. It should be noted that the transition plate 106, the receiving rod 107 and the connecting strip 108 should be higher than the conveyor belt 3 in the initial state. After the convex block 10202 on the moving plate 10201 leaves the extrusion block 101 on the paper product cutting machine 1, the moving plate 10201 will be reset by the spring 104. At the same time, the first electric push rod 105 and the second electric push rod 109 will also drive the transition plate 106, the receiving rod 107 and the connecting strip 108 to be reset, thus preventing the transition plate 106 from affecting the normal operation of the conveyor belt 3.

[0031] The cardboard 10 is transported forward by the conveyor belt 3 and will be transported to the front side of the paper product cutting machine 1. Since there is a gap between the rear side of the transition plate 106 and the front end of the conveyor belt 3, when the cardboard 10 completely leaves the conveyor belt 3, it will stay on the transition plate 106 and the receiving rod 107. At this time, the slider on the electric slide rail 201 drives the parts connected to it to move along the electric slide rail 201, moves the second fixing plate 205 to the rear of the cardboard 10, and then drives the parts connected to it to move downward through the fourth electric push rod 202. Then, the slider on the electric slide rail 201 drives the parts connected to it to move forward along the electric slide rail 201, so that the front side of the second fixing plate 205 contacts the rear side of the cardboard 10. Thus, by continuously moving the slider on the electric slide rail 201 backward along the electric slide rail 201, the entire cardboard 10 is moved onto the receiving rod 107.

[0032] Then, the fourth electric push rod 202 drives the parts connected to it to move upward for resetting, so as to leave the cardboard 10. Then, the slider on the electric slide rail 201 drives the parts connected to it to move backward along the electric slide rail 201, moving the fourth electric push rod 202, the first fixing plate 203, the fifth electric push rod 204, the second fixing plate 205, the electric rotating shaft 206 and the blocking plate 207 above the cardboard 10. Then, the fifth electric push rod 204 pushes the second fixing plate 205, thereby adjusting the gap between the first fixing plate 203 and the second fixing plate 205, so that the gap between the first fixing plate 203 and the second fixing plate 205 can cover the waste 11 on the cardboard 10. Through the visual sensor on the first fixing plate 203, a signal is transmitted to the control box on the paper product cutting machine 1, so that the control box controls the slider on the electric slide rail 201 to drive the parts connected to it to move along the electric slide rail 201, moving the first fixing plate 203 and the second fixing plate 205 between two rows of waste 11 on the cardboard 10. Then, the fourth electric push rod 202 drives the parts connected to it to move downward, making the first fixing plate 203 and the second fixing plate 205 contact the cardboard 10. In this way, the first row of waste 11 counted from the back to the front on the cardboard 10 is covered. At the same time, the cardboard 10 can also be fixed by the first fixing plate 203 and the second fixing plate 205. Then, the sixth electric push rod 301 drives the parts connected to it to move upward, making the air spraying pipe 304 on the mounting plate 302 close to the cardboard 10. Then, the electric slider 303 in the chute 30101 on the mounting plate 302 drives the air spraying pipe 304 to move forward along the chute 30101, moving the nozzle 30401 on the air spraying pipe 304 below the first row of waste 11 counted from the back to the front on the cardboard 10. Then, air is supplied to the air spraying pipe 304 through the air pump communicated with the air spraying pipe 304, and the gas sprays out from the nozzle 30401 on the air spraying pipe 304 to the waste 11 on the cardboard 10, thereby blowing the waste 11 off the cardboard 10. In this way, the removal of the waste 11 on the cardboard 10 is completed. Then, the slider on the electric slide rail 201 drives the parts connected to it and the electric slider 303 on the mounting plate 302 drives the parts connected to it to move backward synchronously, and the waste 11 on the cardboard 10 is removed in sequence.

[0033] The waste material 11 separated from the cardboard 10 will remain on the cardboard 10, resulting in the need for manual removal. At the same time, it will also affect the fixing effect of the first fixing plate 203 and the second fixing plate 205 on the cardboard 10. Therefore, when the waste material 11 is blown off the cardboard 10 by the air jet pipe 304, since the space between the first fixing plate 203 and the second fixing plate 205 is sealed by the elastic cloth 20504, the waste material 11 between the first fixing plate 203 and the second fixing plate 205 can be sucked by the suction pump connected through the first suction groove 20302, so as to clean the waste material 11. At the same time, the debris and powder generated by laser cutting of the cardboard 10 can also be sucked. Due to the limited suction force and some waste materials 11 being in a vertical state and not easily stressed during suction, some waste materials 11 will remain between the first fixing plate 203 and the second fixing plate 205. Therefore, when the air jet pipe 304 jets air on the waste material 11 and the first suction groove 20302 sucks the waste material 11, the blocking plate 207 is in a vertical state, as Figure 7 shown. When the air jet pipe 304 stops jetting air, the blocking plate 207 is driven to rotate by the electric rotating shaft 206 to block the lower openings of the first fixing plate 203 and the second fixing plate 205. The free end of the blocking plate 207 will lean on the clamping groove 20503 on the second fixing plate 205. At this time, the blocking plate 207 is in a state of being higher at the front and lower at the back. Since the diameters of the waste materials 11 on the same batch of goods are not very different, the free end of the blocking plate 207 can always lean on the clamping groove 20503. After the blocking plate 207 blocks the lower openings of the first fixing plate 203 and the second fixing plate 205, the first suction groove 20302 will stop sucking the waste material 11, and the waste material 11 still between the first fixing plate 203 and the second fixing plate 205 will fall on the blocking plate 207. At this time, the waste material 11 on the blocking plate 207 will be sucked through the second suction groove 20303. At this time, it is not necessary to suck the whole waste material 11 in the air. Therefore, the suction difficulty of the waste material 11 is greatly reduced. At the same time, the blocking plate 207 in the state of being higher at the front and lower at the back can also make it slide better into the second suction groove 20303.

[0034] It should be noted that in order to prevent the blocking plate 207 from patting the waste material 11 out of the space between the first fixing plate 203 and the second fixing plate 205 during the process of the electric rotating shaft 206 driving the blocking plate 207 to rotate to block the lower openings of the first fixing plate 203 and the second fixing plate 205, the end part of the rotation trajectory of the blocking plate 207 is blocked by the guiding strip 20502 on the second fixing plate 205, so as to reduce the possibility of the blocking plate 207 patting the waste material 11 out of the space between the first fixing plate 203 and the second fixing plate 205 when rotating. At the same time, the guiding strip 20502 can also guide the waste material 11 towards the second suction groove 20303.

[0035] After the waste 11 on the cardboard 10 is removed, the finished product on the cardboard 10 is still connected to the cardboard 10, so workers are still needed to remove it. Therefore, after the second fixed plate 205 pushes the cardboard 10 onto the receiving rod 107, the third electric push rod 110 will move the positioning plate 111 towards the central axis direction of the paper product cutting machine 1 to position the cardboard 10. At this time, the waste 11 on the cardboard 10 will correspond one by one to the ejector rods 306 on the air jet pipe 304. Then, the third electric push rod 110 will drive the positioning plate 111 to reset. It should be noted that in the initial state of the torsion spring rod 305, the free end of the ejector rod 306 is higher than the upper side of the cardboard 10. During the process of the air jet pipe 304 removing the waste 11, the ejector rod 306 on the air jet pipe 304 will contact the cardboard 10, and the ejector rod 306 will contact the finished product on the cardboard 10 during the continuous movement of the air jet pipe 304, so as to lift the finished product upward. At this time, the cardboard 10 will be fixed by the first fixed plate 203 and the second fixed plate 205. At the same time, the first fixed plate 203 and the second fixed plate 205 have moved to the second finished product from the back to the front. Therefore, the ejector rod 306 can smoothly lift the finished product without lifting the cardboard 10. When the ejector rod 306 moves to the third waste 11 on the finished product from the back to the front, the finished product has completely separated from the cardboard 10. Then, the airbag 307 on the ejector rod 306 will be pumped with air through the connected air pump to make the airbag 307 expand, so as to hang the finished product through the airbag 307. When the ejector rod 306 continues to move forward, it will drive the finished product to move forward on the cardboard 10, which is convenient for subsequent dematerialization of the finished product, thereby improving work efficiency. Then, the airbag 307 will be deflated to make the airbag 307 separate from the cardboard 10. After all the finished products have separated from the cardboard 10, the second fixed plate 205 will push the cardboard 10 forward again for discharging. During this process, the finished product will slide backward due to the friction of the receiving rod 107. Because the cardboard 10 has a certain thickness and the gap between the finished product and the cardboard 10 is small, even if the finished product slides backward, the finished product will finally show an inclined shape with the front high and the back low, thus affecting the dematerialization of the finished product.

[0036] Those skilled in the art of this industry should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
