Description

Technical Field

[0001] This utility model relates to the field of packaging carton processing technology, and specifically to a slotting device for packaging carton processing. Background Technology

[0002] Packaging cartons are foldable containers made of paper materials (mainly corrugated paper). Their core purpose is to contain and protect goods and facilitate transportation and storage. They are one of the most common carriers in logistics and commodity packaging. In the production process of packaging cartons, a grooving device is needed to cut specific grooves, creases or slits into the cardboard, thereby providing the necessary structural foundation for the subsequent folding and forming of the cartons.

[0003] According to the description in the patent application (authorization announcement number: CN214266782U) of a cardboard box slotting machine, "This utility model discloses a cardboard box slotting machine, wherein the connecting plate is fixedly connected to the workbench and is located on one side of the workbench, the connecting plate is provided with a sliding groove, the clamping mechanism is slidably connected to the connecting plate and is located in the sliding groove, before the slotting mechanism is started, the clamping mechanism can be slid according to the size of the cardboard box to correspond with the slotting knife, thereby handling slotting of cardboard boxes of different sizes, one end of the spring is fixedly connected to the sliding frame, the other end of the spring is fixedly connected to the clamping plate, and the spring is located between the sliding frame and the clamping plate, when the slotting mechanism is started, cardboard boxes of different thicknesses can be placed according to the elastic deformation of the spring itself, thereby further improving the adaptability of the cardboard box slotting machine." Regarding the above description, the applicant believes the following problems exist: The grooving blade of the device is fixed on the grooving wheel. If the blade spacing and height need to be adjusted, the machine must be stopped, the grooving wheel must be disassembled, and a grooving wheel with grooving blades of different spacings must be reinstalled or replaced. Height adjustment must be achieved by manually disassembling the grooving wheel, replacing grooving blades of different specifications, or manual calibration. The operation steps are numerous and time-consuming, resulting in low efficiency in adjusting the blade spacing and height of the device. When processing multi-specification cartons, frequent machine stops are required to change parts, which seriously affects production efficiency. At the same time, the grooving mechanism of the device is "directly fixed to the worktable through a connecting frame" without a dedicated vibration damping component, which causes the grooving blade to vibrate easily during the cutting process. The vibration of the blade will cause defects such as "serrated burrs" and "uneven depth" in the cut, resulting in unstable processing quality and defects in the cut. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a grooving device for processing packaging cartons, which has the function of quickly adjusting the spacing and height of the upper grooving knife according to the processing position and thickness of cartons of different specifications. This helps to reduce the downtime of the device for adjustment, thereby improving the production efficiency of the device. It also has the function of absorbing the vibration of the cutting tool during processing, thereby improving the processing stability of the device and thus improving the processing accuracy of the device.

[0005] The objective of this utility model is achieved through the following technical solution: A slotting device for processing packaging cartons includes a mounting frame, a belt feeding mechanism disposed inside the mounting frame, a control device fixedly connected to one side of the mounting frame, a servo motor I fixedly connected to the top of the mounting frame, a rectangular lead screw fixedly connected to the output end of the servo motor I, a sliding block I threadedly connected to the rectangular lead screw, a sliding rod fixedly connected to the inner side of the mounting frame, a sliding block II slidably connected to the outer side of the rectangular lead screw, dampers fixedly connected to the inner sides of sliding block II and sliding block I respectively, a spring fixedly connected to one side of the damper, a pressure sensor fixedly connected to the bottom of the damper, a connecting block I fixedly connected to the bottom of the pressure sensor, and a component fixedly connected inside the connecting block I. The components are: servo motor 2, connecting cylinder fixedly connected to the output end of servo motor 2, conductive slip ring set between connecting block 1 and connecting cylinder, servo motor 3 fixedly connected to the inner side of connecting cylinder, left and right spiral screws fixedly connected to the output end of servo motor 3, upper grooving knife threadedly connected to the left and right spiral screws, displacement sensor 1 fixedly connected to one side of the upper grooving knife, connecting block 2 rotatably connected to one end of connecting cylinder via bearing, servo motor 4 fixedly connected to one side of mounting bracket, irregularly shaped rotating rod fixedly connected to one side of servo motor 4, lower grooving knife slidably connected to the irregularly shaped rotating rod, displacement sensor 2 fixedly connected to the bottom of connecting block 1, and dust collection assembly set outside the mounting bracket.

[0006] In one optional embodiment, a through hole is provided on the mounting bracket, a rectangular lead screw is rotatably connected to the inside of the mounting bracket through the through hole, and a connecting block is fixedly connected to the bottom of the pressure sensor.

[0007] In one optional embodiment, a sliding groove is provided on the lower grooving cutter, and the upper grooving cutter is slidably connected to the inside of the lower grooving cutter through the sliding groove.

[0008] In one optional embodiment, a second through hole is provided on the connecting cylinder, and the left and right rotating screws are rotatably connected to the inside of the connecting cylinder through the second through hole.

[0009] In one optional embodiment, the fixed outer ring of the conductive slip ring is fixedly connected to one side of the connecting block, and the rotating inner ring of the conductive slip ring is fixedly connected to one side of the connecting cylinder.

[0010] In one optional embodiment, the dust collection assembly includes a dust collection box slidably connected inside the mounting frame, a fan fixedly connected to one side of the mounting frame, a connecting hose 2 fixedly connected between the mounting frame and the fan, a filter plate fixedly connected inside the mounting frame, a shaped connecting rod fixedly connected inside the mounting frame, a connecting hose 1 fixedly connected to one side of the mounting frame, a dust collection nozzle fixedly connected to one side of the connecting hose 1, and a sliding block 3 fixedly connected to one side of the dust collection nozzle.

[0011] In one optional embodiment, the sliding block three has an irregularly shaped through hole, and the sliding block three is slidably connected to the irregularly shaped connecting rod through the irregularly shaped through hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The control device starts servo motor one, causing the rectangular lead screw to rotate. The rectangular lead screw drives sliding block one to rise and fall, which in turn drives the upper grooving knife to rise and fall. This facilitates the adjustment of the height of the upper grooving knife, and thus the distance between the upper grooving knife and the irregular rotating rod. Simultaneously, the control device can detect the accuracy of the upper grooving knife height using displacement sensor two. The control device then starts servo motor three, causing displacement sensor one to rotate. Displacement sensor one drives the two sets of upper grooving knives to move synchronously. When servo motor three rotates counterclockwise, the two sets of upper grooving knives move closer to the center of the left and right rotating lead screws. When servo motor three rotates clockwise, the upper grooving knives move to both ends of the left and right rotating lead screws, thus facilitating the adjustment of the distance between the upper grooving knives. Simultaneously, the moving upper grooving knife drives the lower grooving knife to slide on the irregular rotating rod. The control device, through displacement sensor one, detects the accuracy of the distance between the upper grooving knives. This allows users to quickly adjust the distance and height of the upper grooving knives according to the processing position and thickness of different sized cartons, reducing downtime for adjustments and improving production efficiency.

[0013] 2. The vibration generated by cutting the cardboard box is transmitted to the spring through connecting block one and connecting block two. The spring absorbs the vibration peak through elastic deformation. At the same time, the damper converts the vibration energy into heat energy, which increases the amplitude attenuation rate of the vibration frequency. This reduces the impact of vibration on the upper grooving knife, thereby improving the processing stability of the device and thus improving the processing accuracy of the device.

[0020] Please see Figures 1-5This utility model provides an embodiment of a grooving device for processing packaging cartons, comprising a mounting frame 1, characterized in that it further comprises a belt feeding mechanism 2 disposed inside the mounting frame 1, a control device 3 fixedly connected to one side of the mounting frame 1, a servo motor 401 fixedly connected to the top of the mounting frame 1, a rectangular lead screw 402 fixedly connected to the output end of the servo motor 401, a sliding block 403 threadedly connected to the rectangular lead screw 402, a sliding rod 420 fixedly connected to the inner side of the mounting frame 1, a sliding block 404 slidably connected to the outer side of the rectangular lead screw 402, dampers 405 fixedly connected to the inner sides of the sliding block 404 and the sliding block 403 respectively, and a spring 406 fixedly connected to one side of the damper 405. The following components are fixedly connected to the bottom of the damper 405: a pressure sensor 407, a connecting block 408, a servo motor 410, a connecting cylinder 412, a conductive slip ring 411, a servo motor 413, a servo motor 414, a left-hand screw 414, an upper grooving cutter 415, a displacement sensor 416, and a connecting block 412. 09. Servo motor 417 fixedly connected to one side of mounting bracket 1; irregularly shaped rotating rod 418 fixedly connected to one side of servo motor 417; lower grooving blade 419 slidably connected to irregularly shaped rotating rod 418; displacement sensor 421 fixedly connected to the bottom of connecting block 408; and a dust collection assembly installed outside mounting bracket 1. The control device 3 starts servo motor 401 to rotate rectangular lead screw 402, which drives sliding block 403 to rise and fall. Sliding block 403 drives upper grooving blade 415 to rise and fall, thereby facilitating the adjustment of the height of upper grooving blade 415 and the distance between upper grooving blade 415 and irregularly shaped rotating rod 418. Simultaneously, the control device 3 can transmit displacement... Sensor 2 421 detects whether the height of the upper grooving cutter 415 is accurate. Control device 3 starts servo motor 3 413, which drives the left and right rotating lead screw 414 to rotate. The left and right rotating lead screw 414 drives the two sets of upper grooving cutters 415 to move synchronously. When servo motor 3 413 rotates counterclockwise, the two sets of upper grooving cutters 415 move closer to the center of the left and right rotating lead screw 414. When servo motor 3 413 rotates clockwise, the upper grooving cutters 415 move to both ends of the left and right rotating lead screw 414, thus facilitating the adjustment of the distance between the upper grooving cutters 415. Simultaneously, the moving upper grooving cutters 415 drive the lower grooving cutter 419 to slide on the irregular rotating rod 418. Control device 3 detects whether the distance between the upper grooving cutters 415 is correct using displacement sensor 1 416.This allows users to quickly adjust the spacing and height of the upper slotting blade 415 according to the processing position and thickness of different sized cartons, reducing downtime for adjustments and improving production efficiency. The user then activates servo motor 417 via control device 3, causing the irregular rotating rod 418 to rotate the lower slotting blade 419. Simultaneously, servo motor 410 is activated via control device 3, rotating the connecting cylinder 412, which in turn rotates the upper slotting blade 415. The user then places the carton sheet onto the belt conveyor 2, whereby the carton sheet is... The material is transported between connecting block 408 and connecting cylinder 412. Subsequently, the rotating lower grooving blade 419 and upper grooving blade 415 cut and groove the cardboard sheet. Simultaneously, the vibration generated during cutting is transmitted to the spring 406 through connecting block 408 and connecting block 409. The spring 406 absorbs the vibration peak through elastic deformation, while the damper 405 converts the vibration energy into heat energy, increasing the amplitude attenuation rate of the vibration frequency. This reduces the impact of vibration on the upper grooving blade 415, thereby improving the processing stability and accuracy of the device.

[0021] In a preferred embodiment of this utility model, a through hole is provided on the mounting bracket 1, and a rectangular lead screw 402 is rotatably connected to the inside of the mounting bracket 1 through the through hole. A connecting block 409 is fixedly connected to the bottom of the pressure sensor 407, which facilitates the servo motor 401 to drive the rectangular lead screw 402 to rotate, which in turn facilitates the rectangular lead screw 402 to drive the sliding block 403 to rise and fall. Since the connecting block 409 is fixedly connected to the bottom of the pressure sensor 407, the connecting cylinder 412 is rotatably connected to the inside of the connecting block 409, which in turn facilitates the servo motor 410 to drive the connecting cylinder 412 to rotate.

[0022] In a preferred embodiment of this utility model, a sliding groove is provided on the lower grooving cutter 419, and the upper grooving cutter 415 is slidably connected to the inside of the lower grooving cutter 419 through the sliding groove. This facilitates the translation of the upper grooving cutter 415, which can drive the lower grooving cutter 419 to translate, thereby facilitating the adjustment of the position of the lower grooving cutter 419.

[0023] In a preferred embodiment of this utility model, a through hole 2 is provided on the connecting cylinder 412, and the left and right rotating screw 414 is rotatably connected to the inside of the connecting cylinder 412 through the through hole 2, which is conducive to the servo motor 3 413 driving the left and right rotating screw 414 to rotate, which is conducive to the left and right rotating screw 414 driving the upper grooving knife 415 to move horizontally.

[0024] In a preferred embodiment of this utility model, the outer ring of the conductive slip ring 411 is fixedly connected to one side of the connecting block 408, and the inner ring of the conductive slip ring 411 is fixedly connected to one side of the connecting cylinder 412. This facilitates the power supply of the wire to the servo motor 413 through the conductive slip ring 411, thereby preventing the rotating servo motor 413 from tangling the wire.

[0025] Please see Figure 2 and Figure 5 In this embodiment, the vacuuming assembly includes a dust collection box 501 slidably connected inside the mounting frame 1, a fan 507 fixedly connected to one side of the mounting frame 1, a second connecting hose 508 fixedly connected between the mounting frame 1 and the fan 507, a filter plate 506 fixedly connected to the inside of the mounting frame 1, a shaped connecting rod 502 fixedly connected to the inside of the mounting frame 1, a first connecting hose 505 fixedly connected to one side of the mounting frame 1, a vacuum nozzle 504 fixedly connected to one side of the first connecting hose 505, and a third sliding block 503 fixedly connected to one side of the vacuum nozzle 504. When the user moves the upper slot... When the lower grooving knife 419 is moved horizontally by the knife 415, the sliding block 3 503 is moved horizontally by the lower grooving knife 419 because it is slidably connected to the groove of the connecting block 2 409. The control device 3 starts the fan 507, which draws air into the mounting frame 1 through the connecting hose 2 508 and the filter plate 506, thereby creating a negative pressure inside the mounting frame 1. The negative pressure draws the debris generated by the device cutting the cardboard into the suction nozzle 504, and then into the dust collection box 501 through the connecting hose 1 505, which helps to remove the debris and avoids the debris from interfering with and contaminating the device.

[0026] In a preferred embodiment of this utility model, the sliding block 3 503 is provided with an irregular through hole, and the sliding block 3 503 is slidably connected to the irregular connecting rod 502 through the irregular through hole, which facilitates the sliding block 3 503 to slide on the irregular connecting rod 502, thereby preventing the sliding block 3 503 from rotating and thus preventing the suction nozzle 504 from tilting.

[0027] During operation, the control device 3 starts the servo motor 401 to rotate the rectangular lead screw 402. The rectangular lead screw 402 drives the sliding block 403 to rise and fall, and the sliding block 403 drives the upper grooving cutter 415 to rise and fall, thereby facilitating the adjustment of the height of the upper grooving cutter 415 and the distance between the upper grooving cutter 415 and the irregular rotating rod 418. At the same time, the control device 3 can detect whether the height of the upper grooving cutter 415 is accurate through the displacement sensor 421. The control device 3 starts the servo motor 413 to rotate the left and right rotating lead screw 414, which drives the two sets of upper grooving cutters 415 to move synchronously. When the servo motor 413 rotates counterclockwise, the two sets of upper grooving cutters 415 move left and right. As the center of the threaded screw 414 approaches, the servo motor 413 rotates clockwise, causing the upper grooving blade 415 to move horizontally to both ends of the threaded screw 414. This facilitates adjustment of the spacing between the upper grooving blades 415. Simultaneously, the moving upper grooving blade 415 drives the lower grooving blade 419 to slide on the irregular rotating rod 418. The control device 3 detects the correctness of the spacing between the upper grooving blades 415 using the displacement sensor 416. This allows the user to quickly adjust the spacing and height of the upper grooving blades 415 according to the processing position and thickness of different carton specifications, reducing downtime for adjustment and improving production efficiency. Subsequently, the user activates the servo motor 417 via the control device 3 to move the irregular rotating rod 418. The lower grooving blade 419 rotates, and the servo motor 410 is activated by the control device 3 to rotate the connecting cylinder 412. The connecting cylinder 412 then rotates the upper grooving blade 415. The user then places the cardboard box sheet onto the belt conveyor 2, which transports it between the connecting block 408 and the connecting cylinder 412. The rotating lower and upper grooving blades 419 and 415 cut and groov the cardboard box sheet. Simultaneously, the vibration generated during cutting is transmitted to the spring 406 through the connecting block 408 and the connecting block 409. The spring 406 absorbs the vibration peak through elastic deformation, while the damper 405 converts the vibration energy into heat energy, increasing the amplitude attenuation rate of the vibration frequency and thus reducing the impact of vibration on the upper grooving blade. The influence of 415 helps to improve the processing stability of the device and thus improve the processing accuracy. When the user moves the upper grooving cutter 415 to drive the lower grooving cutter 419 to move horizontally, the sliding block 3 503 is driven to move horizontally by the lower grooving cutter 419 because it is slidably connected to the sliding groove of the connecting block 2 409. The control device 3 starts the fan 507, and the fan 507 draws air into the mounting frame 1 through the connecting hose 2 508 and the filter plate 506, thereby creating a negative pressure inside the mounting frame 1. The negative pressure draws the debris generated by the device cutting the cardboard pieces into the dust suction nozzle 504, and then into the dust collection box 501 through the connecting hose 1 505, which helps to remove the debris and avoids the debris from interfering with and contaminating the device.
