Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0027] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0028] refer to Figure 1-11 .

[0029] This utility model provides a sheet slitting machine, comprising an unwinding mechanism 1, a leveling mechanism 2, a longitudinal slitting mechanism 3, a first conveying mechanism 4, a reversing stacking mechanism 5, a second conveying mechanism 6, a transverse slitting mechanism 7, a third conveying mechanism 8, a transverse stacking mechanism 9, a fourth conveying mechanism 10, a longitudinal stacking mechanism 11, and a fifth conveying mechanism 12. The unwinding mechanism 1 is used to load and unwind the sheet roll; the leveling mechanism 2 is used to level the material; the longitudinal slitting mechanism 3 is used to cut the material longitudinally into several strips; the first conveying mechanism 4 is used to convey the material to the reversing stacking mechanism 5; the reversing stacking mechanism 5 is used to cut the several strips... The materials are oriented and stacked together; the second conveying mechanism 6 is used to convey the stacked strip materials to the side of the cross-cutting mechanism 7; the cross-cutting mechanism 7 is used to cut the stacked strip materials into sheet materials in the transverse direction; the third conveying mechanism 8 is used to convey the stacked sheet materials to the side of the transverse stacking mechanism 9; the transverse stacking mechanism 9 is used to perform transverse stacking operation on the stacked sheet materials; the fourth conveying mechanism 10 is used to convey the stacked sheet materials to the side of the fifth conveying mechanism 12; the longitudinal stacking mechanism 11 is used to perform longitudinal stacking operation on the stacked sheet materials; the fifth conveying mechanism 12 is used to output the stacked sheet materials.

[0030] Its working principle is as follows: the material roll is loaded onto the unwinding mechanism 1, which unwinds the material roll and the leveling mechanism 2 levels the material. Then, the longitudinal cutting mechanism 3 cuts the material longitudinally into several strips. The reversing stacking mechanism 5 adjusts the direction of all the strips and stacks them together. Next, the transverse cutting mechanism 7 cuts the stacked strips transversely into a stack of sheets. The third conveying mechanism 8 conveys the stack of sheets to the transverse stacking mechanism 9. Finally, the transverse stacking mechanism 9 levels the stack of sheets. The sheet material is horizontally flattened. During the process of conveying the stack of sheet material to the fifth conveyor 12 by the fourth conveyor 10, the stack of sheet material is vertically flattened by the longitudinal flattening mechanism 11. After the fourth conveyor 10 conveys the stack of sheet material to the fifth conveyor 12, the fifth conveyor 12 outputs and unloads the stack of sheet material. This realizes the automation of feeding, flattening, longitudinal cutting, stacking, transverse cutting, stacking, and unloading, effectively saving manpower, improving production efficiency, reducing production costs, and ensuring stable processing quality.

[0031] Based on the above embodiments, the leveling mechanism 2 includes a first body 20 and two leveling modules 21. The first body 20 includes two opposing first side plates 200. The leveling module 21 includes a first support plate 210 fixedly connected between the tops of the two first side plates 200 and a pressing assembly 211. The pressing assembly 211 includes pressing cylinders 211a respectively disposed on both sides of the bottom of the first support plate 210 and a pressure plate 211b connected between the output shafts of the two pressing cylinders 211a. During the forward conveying of material between the first support plate 210 and the pressure plate 211b, the pressing cylinders 211a drive the pressure plate 211b to rise and fall to adjust the distance between the pressure plate 211b and the first support plate 210. The material is leveled when passing between the first support plate 210 and the pressure plate 211b.

[0032] Based on the above embodiments, the longitudinal cutting mechanism 3 includes a cutter 30 and a rotation adjustment assembly 31. The cutter 30 includes a rotating shaft 300 rotatably connected between two first side plates 200 and several longitudinal cutters 301 arranged side by side on the rotating shaft 300. The rotation adjustment assembly 31 includes a worm gear 310 and a worm 311. The worm gear 310 is connected to one end of the rotating shaft 300, and the worm 311 is rotatably connected to one of the first side plates 200 and meshes with the worm gear 310. A handwheel 312 is connected to the top of the worm 311. By rotating the handwheel 312, the worm 311 can be rotated, thereby causing the rotating shaft 300 to rotate forward or backward to adjust the angle of the longitudinal cutters 301. During the forward conveying of the material, the multiple longitudinal cutters 301 cut the material into several long strips.

[0033] Based on the above embodiments, the reversing stacking mechanism 5 includes a second support plate 50 fixedly connected between the tops of the two first side plates 200 and several guide rods 51 arranged side by side on the top of the second support plate 50. Strip-shaped materials are conveyed to the guide rods 51 under the drive of the first conveying mechanism 4. The guide rods 51 can be installed at a 45° angle to the input direction of the material. The strip-shaped materials pass under the guide rods 51 and are then conveyed to the second conveying mechanism 6 at a 90° angle to the input direction, thereby realizing a change in the conveying direction of the strip-shaped materials to shorten the length of the production line. Furthermore, all strip-shaped materials can be stacked together and conveyed to the second conveying mechanism 6, facilitating the simultaneous transverse cutting of multiple strip-shaped materials.

[0034] Based on the above embodiments, the cross-cutting mechanism 7 includes a second body 70, a cross-cutting blade wheel 71, a blade wheel rotation drive mechanism, and a lower cutter 72. The second body 70 includes two opposing second side plates 700. The cross-cutting blade wheel 71 includes a blade wheel 710, a rotating shaft 711 connected to both ends of the blade wheel 710, and a plurality of cross-cutting blades 712. A plurality of right-angle notches 710a are evenly distributed on the surface of the blade wheel 710. The cross-cutting blades 712 are fixedly connected to the right-angle notches 710a and their cutting edges extend beyond the surface of the blade wheel 710. A bearing seat 701 is provided on the top of the second side plate 700. The rotating shaft 711 and the bearing seat 701 are connected by a bearing. The lower cutter 72 is disposed between the two second side plates 700 and located below the cross-cutting blade wheel 71. The blade wheel rotation drive mechanism includes a first servo motor 73 disposed on one of the second side plates 700. The first servo motor 73 and one of the rotating shafts 711 are connected by a synchronous belt drive. When a stack of strip materials is conveyed between the cutter wheel 710 and the lower cutter 72, the first servo motor 73 drives the cross-cutting cutter wheel 71 to rotate, so that the cross-cutting blade 712 and the lower cutter 72 can perform a transverse cutting operation on the stack of strip materials, thereby cutting the stack of strip materials into a stack of sheet materials.

[0035] Based on the above embodiments, the transverse stacking mechanism 9 includes a third body 90, a front material feeding module 91, and a rear material feeding module 92. Both the front material feeding module 91 and the rear material feeding module 92 include a first gantry frame 910 and a plurality of material feeding components 911 mounted on the third body 90. Each material feeding component 911 includes a third support plate 911a fixedly connected to the first gantry frame 910, a first material feeding drive cylinder 911b mounted on the third support plate 911a, and an L-shaped material feeding plate 912 driven and connected to the first material feeding drive cylinder 911b. The L-shaped material feeding plate 912 includes a vertical plate 912a, a guide inclined plate 912b connected to the top of the vertical plate 912a, and a horizontal support plate 912c connected to the bottom of the vertical plate 912a. The first material-tapping drive cylinder 911b drives the L-shaped material-tapping plate 912 to move back and forth, so that the distance between the vertical plates 912a of the two opposing L-shaped material-tapping plates 912 matches the width of the sheet material. The third conveying mechanism 8 conveys the cross-cut stack of sheet material to the lateral stacking mechanism 9. The stack of sheet material is guided between the two vertical plates 912a through the two guide inclined plates 912b, and is supported by the two horizontal support plates 912a, thus completing the lateral stacking operation of the stack of sheet material. When the two first material-tapping drive cylinders 911b drive the L-shaped material-tapping plate 912 to move backward, the entire stack of sheet material will fall onto the fourth conveying mechanism 10 and be conveyed forward.

[0036] Based on the above embodiments, the fourth conveying mechanism 10 includes several fourth pallets 100 arranged in parallel on the top of the third body 90, a lifting pusher arm 101, and a horizontal drive mechanism 102. Adjacent fourth pallets 100 are spaced apart to form strip-shaped clearance grooves 100a. The horizontal drive mechanism 102 includes a horizontal slide plate 102a slidably connected to the third body 90 in the horizontal direction and a horizontal drive cylinder 102b arranged on the third body 90 and drivenly connected to the horizontal slide plate 102a. The lifting pusher arm 101 includes several lifting cylinders 101a arranged in parallel on the top of the horizontal slide plate 102a, a lifting plate 101b connected between the output shafts of the several lifting cylinders 101a, and several pusher arm groups 102 arranged in parallel on the lifting plate 101b. The pusher arm group 102 includes several pusher arms 102a fixedly connected to the top of the lifting plate 101b and corresponding to the strip-shaped clearance grooves 100a. After the stack of sheet material falls onto the fourth pallet 100, the lifting cylinder 101a drives the lifting plate 101b to rise, allowing the pusher arm 102a to extend out of the top surface of the strip-shaped clearance groove 100a. The horizontal drive cylinder 102b drives the horizontal slide plate 102a to move forward a certain distance, allowing the pusher arm 102a to push the stack of sheet material forward along the fourth pallet 100 a certain distance. After the next stack of sheet material falls onto the fourth pallet 100, the lifting cylinder 101a drives the lifting plate 101b to descend, allowing the pusher arm 102a to retract below the strip-shaped clearance groove 100a. The above actions are repeated in a cycle, which can realize the simultaneous conveying of multiple stacks of sheet material and separate each stack of sheet material into the spacing of two pusher arms 102a of two adjacent pusher arm groups 102. The fourth conveying mechanism 10 can convey the stack of sheet material to the fifth conveying mechanism 12.

[0037] Based on the above embodiments, the longitudinal stacking mechanism 11 includes a left-side material-tapping module 91 and a right-side material-tapping module 92 disposed opposite to each other on both sides of the third body 90. Both the left-side and right-side material-tapping modules 91 and 92 include a second material-tapping drive cylinder 110a fixedly connected to the third body 90 and a material-tapping plate 110b driven by the second material-tapping drive cylinder 110a. When the horizontally stacked stack of sheet material is conveyed between the two material-tapping plates 110b under the drive of the fourth conveying mechanism 10, the second material-tapping drive cylinders 110a of the left-side and right-side material-tapping modules 91 and 92 simultaneously drive the material-tapping plates 110b to move closer, thereby performing a longitudinal stacking operation on the stack of sheet material.

[0038] Based on the above embodiments, a first ion air bar 22 is provided between the tops of the two first side plates 200 to realize the static removal operation of the material.
