Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and in particular to a cardboard box processing printing and slotting device. Background Technology

[0002] Cardboard boxes are the most widely used packaging products, used as wrapping materials for goods or as outer protective layers for items. They are classified by material into corrugated cardboard boxes, single-layer cardboard boxes, etc. Printing and slotting machines are the core equipment for post-processing of cardboard boxes, integrating five processes: printing, slotting, creasing, corner cutting, and edge cutting. Through the configuration of multiple printing units, they can achieve single-color to four-color printing functions.

[0003] Existing printing slotting devices typically adjust the slotting position by moving a roller seat with blades mounted on a slide rail. The positioning relies entirely on initial mechanical calibration and manual judgment, lacking real-time monitoring of the blade position during processing. In actual production, impacts from cardboard seams, changes in cutting resistance, mechanical vibrations of the equipment, and even minor human collisions can cause slight displacement of the roller seat carrying the blades, resulting in deviations in the slotting position of batches of cartons and creating batches of waste. Utility Model Content

[0004] This utility model discloses a cardboard box processing and printing slotting device, which aims to solve the technical problem that current processing devices cannot monitor the accuracy of the cardboard box slotting position in real time during the processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cardboard box processing and printing slotting device includes a base platform and a top platform. Side boxes are fixedly connected to both sides of the base platform and the top platform. Two vertically distributed slide rails are arranged between the base platform and the top platform. Two vertically distributed rotating cylinders are arranged between the two slide rails. The two ends of the slide rails are fixedly connected to the side boxes. The two ends of the rotating cylinders are rotatably connected to the side boxes through bearings. Multiple upper-positioned transfer seats are slidably connected to the upper slide rail. Each upper-positioned transfer seat is equipped with a slot self-inspection component. The slot self-inspection component includes a laser emitter. The laser emitter is fixedly connected to the outer surface of the upper-positioned transfer seat. A hanger is arranged above the laser emitter, and a receiver for receiving the laser emitter signal is fixedly connected to the hanger.

[0006] In a preferred embodiment, the slot self-inspection component further includes a top rail, which is fixedly connected to the upper side of the top platform. Multiple shift seats are slidably connected to the top rail, and the hanger is fixedly connected to the shift seats. A groove is provided on the top platform, and a scale plate is fixedly connected inside the groove. A pointer is fixedly connected to the lower side of the hanger, and the pointer points to the scale plate.

[0007] In a preferred embodiment, the shifting seat has a threaded hole, and a shifting screw is rotatably connected to the inside of the threaded hole through an inner wall thread. A shifting motor is fixedly connected to one side of the side box, and the output shaft of the shifting motor is connected to one end of the shifting screw through a coupling.

[0008] In a preferred embodiment, an upper roller is rotatably connected to the upper traction seat via a bearing, and a blade is provided on the upper roller. A lower traction seat is provided below the upper traction seat, and a lower roller is rotatably connected to the lower traction seat via a bearing. The lower roller is provided with a blade groove that cooperates with the blade.

[0009] In a preferred embodiment, the lower traction seat is slidably connected to the lower slide rail, the upper roller and the lower roller are respectively sleeved on the outside of the two rotating drums, and both the lower traction seat and the upper traction seat are provided with threaded holes. The inside of each threaded hole is rotatably connected to an adjusting screw through an inner wall thread. An adjusting motor is fixedly connected to the outside of the side box, and the output shaft of the adjusting motor is connected to one end of the adjusting screw through a coupling.

[0010] In a preferred embodiment, each of the lower traction seats is equipped with a roller groove anti-jamming component.

[0011] In a preferred embodiment, the anti-jamming assembly of the roller groove includes a back frame, which is fixedly connected to the outer surface of the lower traction seat. A support rod is fixedly and adjustablely connected to the back frame by bolts, and a circular hole is opened at the upper end of the support rod. A rotating rod is rotatably connected to the inside of the circular hole through a bearing. A paddle is fixedly connected to the top end of the rotating rod, and the paddle is located in the cutter groove. A coil spring is sleeved at the end of the rotating rod. One end of the coil spring is connected to the rotating rod, and the other end is connected to the support rod, which is used to provide the torque for the paddle to reset.

[0012] As can be seen from the above, the cardboard processing and printing slotting device provided by this utility model has a dual positioning and monitoring mechanism achieved through the coordinated work of the laser emitter, receiver, scale plate and pointer in the slot self-inspection component: During adjustment, the operator can pre-drive the shift seat through the shift motor and perform coarse positioning by referring to the reading on the scale plate by the pointer; during processing, the laser emitter intermittently emits laser signals upward and is received by the receiver, forming a real-time optical monitoring system. Once the upper shift seat (carrying the slotting blade) undergoes a slight displacement due to mechanical vibration, cutting resistance or external force collision, the laser signal will deviate, and the system can promptly alarm or stop the machine, thereby effectively avoiding the generation of batches of waste products and ensuring the technical effect of absolute accuracy of the slotting position.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] The cardboard box processing and printing slotting device disclosed in this utility model is mainly used in scenarios where current processing devices cannot monitor the accuracy of the cardboard box slotting position in real time during the processing.

[0020] Reference Figures 1-4 A cardboard box processing and printing slotting device includes a base platform 1 and a top platform 2. Side boxes 3 are fixedly connected to both sides of the base platform 1 and the top platform 2. Two vertically distributed slide rails 4 are arranged between the base platform 1 and the top platform 2. Two vertically distributed rotating cylinders 5 are arranged between the two slide rails 4. The two ends of the slide rails 4 are fixedly connected to the side boxes 3. The two ends of the rotating cylinders 5 are rotatably connected to the side boxes 3 through bearings. Multiple upper-positioned transfer seats 6 are slidably connected to the upper slide rails 4. Each upper-positioned transfer seat 6 is provided with a slot self-inspection component 7. The slot self-inspection component 7 includes a laser emitter 701. The laser emitter 701 is fixedly connected to the outer surface of the upper-positioned transfer seat 6. A hanger 702 is arranged above the laser emitter 701. A receiver 703 for receiving the signal from the laser emitter 701 is fixedly connected to the hanger 702.

[0021] In this solution, the slot self-inspection component 7 also includes a top rail 704, which is fixedly connected to the upper side of the top platform 2. Multiple shift seats 705 are slidably connected on the top rail 704. The hanger 702 is fixedly connected to the shift seats 705. A groove is provided on the top platform 2. A scale plate 706 is fixedly connected inside the groove. A pointer 707 is fixedly connected to the lower side of the hanger 702. The pointer 707 points to the scale plate 706.

[0022] In this scheme, the shift seat 705 is provided with a threaded hole, and the inside of the threaded hole is rotatably connected to the shift screw 8 through the inner wall thread. The side of the side box 3 is fixedly connected to the shift motor 9, and the output shaft of the shift motor 9 is connected to one end of the shift screw 8 through a coupling.

[0023] When adjusting the slot position: First, start the shift motor 9 to drive the shift screw 8 to rotate (one shift screw 8 drives the two outermost shift seats 705 to move, the other shift screw 8 drives the two middle shift seats 705 to move, and the middle shift seat 705 remains stationary). The shift seats 705 move to the preset positions respectively, and the pointer 707 indicates on the scale plate 706 whether the preset position has been reached. Subsequently, multiple upper traction seats 6 are adjusted to reach the preset position. After completion, the laser emitter 701 will intermittently transmit signals throughout the entire operation (the transmission time interval is 3 minutes) to determine the position information of the upper traction seats 6 (whether the grooving position has deviated) and avoid the grooving position deviation caused by the resistance of the cutting process, mechanical vibration or human collision.

[0024] The device achieves a dual positioning and monitoring mechanism through the coordinated operation of the laser emitter 701, receiver 703, scale plate 706, and pointer 707 in the slot self-inspection component 7: During adjustment, the operator can pre-drive the shift seat 705 through the shift motor 9 and perform coarse positioning by referring to the reading on the scale plate 706 by the pointer 707; During processing, the laser emitter 701 intermittently emits laser signals upwards and is received by the receiver 703, forming a real-time optical monitoring system. Once the upper traction shift seat 6 (carrying the grooving blade) undergoes a slight displacement due to mechanical vibration, cutting resistance, or external force collision, the laser signal will deviate, and the system can promptly alarm or stop the machine, thereby effectively avoiding the generation of batches of defective products and ensuring the absolute accuracy of the grooving position.

[0025] Reference Figure 2 , Figure 3 and Figure 4In a preferred embodiment, an upper roller 10 is rotatably connected to the upper traction seat 6 via a bearing, and a blade is provided on the upper roller 10. A lower traction seat 11 is provided below the upper traction seat 6, and a lower roller 12 is rotatably connected to the lower traction seat 11 via a bearing. The lower roller 12 is provided with a blade groove 13 that cooperates with the blade.

[0026] In this scheme, the lower traction seat 11 is slidably connected to the lower slide rail 4, the upper roller 10 and the lower roller 12 are respectively sleeved on the outside of the two rotating drums 5, and both the lower traction seat 11 and the upper traction seat 6 are provided with threaded holes. The inside of the threaded holes is rotatably connected to the adjusting screw 14 through the inner wall thread. The outside of the side box 3 is fixedly connected to the adjusting motor 15, and the output shaft of the adjusting motor 15 is connected to one end of the adjusting screw 14 through a coupling.

[0027] The upper traction seat 6 and the lower traction seat 11 move in the same way as the shift seat 705. The shifting motor 15 drives the shifting screw 14 to rotate, so that the middle traction seat is stationary and the traction seats on both sides move away from or closer to each other. The carton is cut and slotted by the blade on the upper roller 10 between the upper traction seat 6 and the lower traction seat 11. The upper roller 10 and the lower roller 12 rotate to complete the continuous processing of the carton. The slotting of the carton by the blade is completed at the position of the slot 13.

[0028] Reference Figure 2 and Figure 4 In a preferred embodiment, each of the lower traction seats 11 is equipped with a roller groove anti-jamming component 16.

[0029] In this solution, the anti-jamming assembly 16 of the roller groove includes a back frame 1601, which is fixedly connected to the outer surface of the lower traction seat 11. A support rod 1602 is fixedly connected to the back frame 1601 by bolts, and a round hole is opened at the upper end of the support rod 1602. A rotating rod 1603 is rotatably connected to the inside of the round hole through a bearing. A paddle 1604 is fixedly connected to the top end of the rotating rod 1603. The paddle 1604 is located in the cutter groove 13. A coil spring 1605 is sleeved at the end of the rotating rod 1603. One end of the coil spring 1605 is connected to the rotating rod 1603, and the other end is connected to the support rod 1602, which is used to provide the torque for the paddle 1604 to reset.

[0030] During the cutting and grooving process of the carton, the blade of the upper roller 10 provides downward pressure during the grooving process. As the cut paper strips are embedded in the knife groove 13 of the lower roller 12, the rotation of the lower roller 12 will seriously affect the subsequent cutting and grooving process, causing mechanical blockage and blade load. During the rotation of the lower roller 12, the anti-jamming component 16 uses the inserting of the paddle 1604 into the knife groove 13 to remove the paper strip embedded inside the knife groove 13, ensuring that the knife groove 13 is in normal working condition. During this process, the paddle 1604 provides a better working method under the elastic force of the coil spring 1605. After the paddle 1604 flips, it returns to its original position under the elastic property of the coil spring 1605, which causes the paper strip inside the knife groove 13 to fall off quickly.

[0031] The device innovatively incorporates a roller groove anti-jamming component 16 at the lower roller 12. This component utilizes a paddle 1604 located within the knife groove 13 to automatically scrape out paper scraps or strips embedded in the knife groove 13 after cutting during the rotation of the lower roller 12. Its coil spring 1605 design allows the paddle 1604 to temporarily flip and avoid significant resistance, and automatically spring back to its original position after the resistance disappears. This ensures the cleaning effect while preventing damage to itself, fundamentally eliminating problems such as downtime for cleaning, increased equipment load, and even blade damage caused by blockage of the knife groove 13. This significantly reduces the frequency of equipment maintenance and improves overall production efficiency.

[0032] Working principle: When adjusting the slot position: First, start the shift motor 9 to drive the shift screw 8 to rotate (one shift screw 8 drives the two outermost shift seats 705 to move, the other shift screw 8 drives the two middle shift seats 705 to move, and the middle shift seat 705 remains stationary). The shift seats 705 move to the preset positions respectively, and the pointer 707 indicates on the scale plate 706 whether the preset position has been reached. Subsequently, multiple upper traction seats 6 are adjusted to reach the preset position. After completion, the laser emitter 701 will intermittently transmit signals throughout the entire operation (the transmission time interval is 3 minutes) to determine the position information of the upper traction seats 6 (whether the grooving position has deviated) and avoid the grooving position deviation caused by the resistance of the cutting process, mechanical vibration or human collision. The process of cutting and slotting cardboard boxes: Because the blade of the upper roller 10 provides downward pressure during the grooving process, the cut paper strip may become embedded in the groove 13 of the lower roller 12. At this time, the anti-jamming component 16 removes the paper strip embedded in the groove 13 by inserting the paddle 1604 into the groove 13 during the rotation of the lower roller 12, ensuring that the groove 13 is in normal working condition.

[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
