Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard processing equipment, and in particular to a laser positioning corrugated cardboard slitting device. Background Technology

[0002] Corrugated cardboard is a widely used paper packaging material. Its structure consists of at least one layer of corrugated core paper bonded to one or more layers of flat linerboard. The corrugated core forms a series of micro-support units, which significantly improves the compressive strength and shock absorption of the cardboard while reducing its weight. The air structure in the interlayer also provides some thermal insulation and shock absorption. Corrugated cardboard is widely used in packaging products such as cartons, boxes, and cushioning pads, and is an important basic material in logistics, warehousing, and commodity transportation. Before use, large-format corrugated cardboard usually needs to be cut into boards of specified sizes using slitting equipment.

[0003] Although existing slitting devices are widely used in production practice, they still have significant technical limitations. During continuous high-speed slitting, current equipment is prone to cutting errors due to factors such as insufficient stability of the transmission system, deviation in the positioning accuracy of the cutter holder, or equipment vibration. This results in poor consistency of slitting dimensions, burrs or tears on the edges, which not only reduces material utilization but also affects the quality of subsequent processing and overall production efficiency.

[0004] Therefore, a laser-positioned corrugated cardboard slitting device needs to be designed. Utility Model Content

[0005] In order to overcome the shortcomings of existing corrugated cardboard slitting devices, such as low cutting accuracy, easy errors during the cutting process, and reduced production efficiency, this utility model provides a laser positioning corrugated cardboard slitting device.

[0006] Technical Solution: A laser-positioned corrugated cardboard slitting device includes a frame, a controller, a first motor, a screw, a slitting blade, a collar, a second motor, a gear, a gear ring, an electric slide rail, an electric slider, a laser emitter, and a positioning sensor. The controller is mounted on the top front side of the frame. The first motor is also mounted on the front side of the frame and is electrically connected to the controller. A screw is connected to the output shaft of the first motor, and a collar is threaded onto the screw. The collar is slidably connected to the frame. A slitting blade is rotatably connected to the outside of the collar. The second motor is mounted on the right side of the collar and is electrically connected to the controller. A gear is connected to the output shaft of the second motor. A gear ring is fixedly connected to the front side of the slitting blade, and the gear and gear ring mesh with each other. An electric slide rail is mounted inside the front side of the frame, and an electric slider is slidably mounted on the electric slide rail. A laser emitter is mounted on the right side of the electric slider. A positioning sensor is mounted on the top front side of the frame. The electric slide rail, electric slider, laser emitter, and positioning sensor are all electrically connected to the controller.

[0007] Furthermore, it also includes a conveyor roller 1, a motor 3, and a pulley assembly 1. Multiple conveyor rollers 1 are rotatably connected between the front and rear ends on the left side of the machine frame. A motor 3 is installed on the front side of the machine frame. The motor 3 is electrically connected to the controller. The output shaft of the motor 3 is connected to the leftmost conveyor roller 1. Power is transmitted between every two adjacent conveyor rollers 1 through the pulley assembly 1.

[0008] Furthermore, it also includes a second conveyor roller and a second pulley assembly. Multiple second conveyor rollers are rotatably connected between the front and rear ends on the right side inside the frame. Power is transmitted between every two adjacent second conveyor rollers through a first pulley assembly, and power is transmitted between the rightmost first conveyor roller and the leftmost second conveyor roller through a second pulley assembly.

[0009] Furthermore, it also includes a slide rod, a connecting block, a spring, and a pressure roller. The slide rod is fixedly connected to the rear side of the frame, the connecting block is slidably connected to the outside of the slide rod, a spring is connected between the slide rod and the connecting block, and a pressure roller is fixedly connected to the front side of the connecting block. The pressure roller is slidably connected to the frame.

[0010] Furthermore, it also includes a blanking plate, which is fixedly connected to the right side of the frame.

[0011] Furthermore, the slitting blade is a circular saw blade.

[0012] Beneficial effects: 1. The positioning sensor detects the position of the corrugated cardboard and feeds it back to the controller. The controller controls the laser emitter to accurately mark the cutting trajectory through preset parameters. Then, the motor adjusts the horizontal position of the cutting blade to cut along the trajectory. This solves the problem of low cutting accuracy of existing corrugated cardboard cutting devices, which are prone to errors during the cutting process and reduce production efficiency.

[0013] 2. By setting up a sliding rod, connecting block, spring and pressure roller, the spring force keeps the pressure roller tightly pressed on the corrugated board during the conveying process, effectively preventing the corrugated board from shifting or tilting during the conveying process and ensuring the stability of the conveying.

Detailed Implementation

[0022] Example: A laser-positioned corrugated cardboard slitting device, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the assembly includes a frame 1, a controller 2, a first motor 3, a screw 4, a slitting blade 5, a collar 501, a second motor 6, a gear 7, a gear ring 8, an electric slide rail 9, an electric slider 10, a laser emitter 11, and a positioning sensor 12. The controller 2 is mounted on the top front of the frame 1, and the first motor 3 is mounted on the front of the frame 1. The first motor 3 is electrically connected to the controller 2. The screw 4 is connected to the output shaft of the first motor 3, and a collar 501 is threaded onto the screw 4. The collar 501 is slidably connected to the frame 1. The slitting blade 5 is rotatably connected to the outside of the collar 501. The slitting blade 5 is a circular saw blade made of high-speed steel and has relatively high... High hardness and wear resistance ensure neatness and durability of the slitting. A motor 6 is installed on the right side of the collar 501. The motor 6 is electrically connected to the controller 2. A gear 7 is connected to the output shaft of the motor 6. A gear ring 8 is welded to the front side of the slitting blade 5. The gear 7 and the gear ring 8 mesh with each other. An electric slide rail 9 is installed on the front side inside the frame 1. An electric slider 10 is slidably installed on the electric slide rail 9. A laser emitter 11 is installed on the right side of the electric slider 10. A positioning sensor 12 is installed on the front top of the frame 1. The electric slide rail 9, the electric slider 10, the laser emitter 11 and the positioning sensor 12 are all electrically connected to the controller 2.

[0023] like Figure 1 and Figure 5As shown, it also includes a first conveyor roller 13, a third motor 14, a first pulley assembly 15, a second conveyor roller 16, and a second pulley assembly 17. Three first conveyor rollers 13 are rotatably connected between the front and rear ends on the left side inside the frame 1. The third motor 14 is installed on the front side of the frame 1 and is electrically connected to the controller 2. The output shaft of the third motor 14 is connected to the leftmost first conveyor roller 13. Power is transmitted between every two adjacent first conveyor rollers 13 through the first pulley assembly 15. Two second conveyor rollers 16 are rotatably connected between the front and rear ends on the right side inside the frame 1. Power is transmitted between every two adjacent second conveyor rollers 16 through the first pulley assembly 15. Power is transmitted between the rightmost first conveyor roller 13 and the leftmost second conveyor roller 16 through the second pulley assembly 17, so as to achieve stable conveying of corrugated cardboard.

[0024] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a slide bar 18, a connecting block 19, a spring 20, a pressure roller 21, and a discharge plate 22. The slide bar 18 is welded to the rear side of the frame 1. The connecting block 19 is slidably connected to the outside of the slide bar 18. A spring 20 is connected between the slide bar 18 and the connecting block 19. The spring 20 is sleeved on the outside of the slide bar 18. The pressure roller 21 is welded to the front side of the connecting block 19. The pressure roller 21 is slidably connected to the frame 1. The elastic force of the spring 20 can make the pressure roller 21 always press tightly on the corrugated cardboard, effectively preventing the corrugated cardboard from shifting or tilting during the conveying process and ensuring the stability of the conveying. The discharge plate 22 is welded to the right side of the frame 1.

[0025] When corrugated cardboard needs to be slit, the operator first starts motor 6, laser emitter 11, positioning sensor 12 and motor 14 through controller 2. The output shaft of motor 14 rotates, driving the leftmost conveyor roller 13 to rotate, which in turn drives the adjacent conveyor roller 13 to rotate synchronously through pulley assembly 15. The corrugated cardboard to be slit can then be placed on conveyor roller 13 and conveyed to the right. The output shaft of motor 6 rotates, driving gear 7 to rotate. Since gear 7 meshes with gear ring 8, the gear ring 8 drives the slitting blade 5 to rotate at high speed.

[0026] During the conveying process, the spring force of spring 20 keeps the pressure roller 21 pressed tightly against the corrugated cardboard, ensuring the stability of the conveying. When the corrugated cardboard is conveyed to the near-cutting position, the positioning sensor 12 detects the position of the corrugated cardboard and transmits the detection signal to the controller 2. The controller 2 controls the electric slider 10 to slide on the electric slide rail 9 according to the preset cutting parameters, so that the clear laser line emitted by the laser emitter 11 moves to the set cutting position, thereby marking the cutting trajectory on the corrugated cardboard. The motor 3 starts and its output shaft rotates, driving the screw 4 to rotate, so that the collar 501 moves horizontally until the cutting blade 5 moves to the laser-marked cutting trajectory, and then the motor 3 is turned off. When the cutting blade 5 rotates at high speed and contacts the corrugated cardboard, it performs the cutting operation.

[0027] After the corrugated cardboard is cut, it continues to be conveyed to the right. The rightmost conveyor roller 13 drives the leftmost conveyor roller 16 to rotate through the belt pulley assembly 27. The leftmost conveyor roller 16 drives all the conveyor rollers 16 to rotate synchronously through the belt pulley assembly 15, conveying the cut corrugated cardboard to the drop plate 22 and then dropping it. After all the corrugated cardboard is cut, the motor 26, laser emitter 11, positioning sensor 12 and motor 3 14 are turned off, thus completing the corrugated cardboard cutting operation of this device.
