[0003] Traditional cardboard production cutting equipment consists of a simple workbench and manual cutting tools. When using it, the operator lays the cardboard flat on the workbench, determines the cutting size by visual inspection or simple measuring tools, and then uses a manual cutting tool to cut along the marked lines. This manual cutting method results in uneven cutting lines, difficulty in ensuring dimensional accuracy, and a high scrap rate. Secondly, manual cutting is inefficient and cannot meet the needs of large-scale production. In addition, prolonged manual operation increases the labor intensity of operators and poses certain safety hazards.

[0004] To address the problems of traditional manual cutting, existing technologies have developed automated cutting equipment. This equipment uses fixed cutting tools, transmission mechanisms, and positioning baffles to achieve automated cutting of cardboard. However, in practical use, it is difficult to adapt to the positioning requirements of cardboard of different lengths. When cutting cardboard of different lengths, the fixed position of the positioning baffles cannot be flexibly adjusted according to the length of the cardboard. Therefore, a distance-adjustable cutting device for cardboard production is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] See attached document Figure 1 Appendix Figure 3 and attached Figure 4 This utility model provides an embodiment of a distance-adjustable cardboard cutting device, including a machine tool 1. The machine tool 1 is equipped with a transport mechanism 6 for transporting cardboard. Two slides 2 are fixedly connected to the top right side of the machine tool 1 to provide an installation base and sliding guide for the distance adjustment mechanism 3. The distance adjustment mechanism 3 is provided between the two adjacent slides 2 to adjust the lateral position to adapt to different cardboard positioning requirements. A cutting table 4 is fixedly connected to the inner wall of the machine tool 1 to provide a stable support plane for cardboard cutting. A collection mechanism 5 is provided at the bottom of the cutting table 4 to collect waste debris generated during the cutting process. A distance sensor 8 is fixedly connected to the top rear side of the machine tool 1 to monitor the cardboard position in real time.

[0034] The adjustment mechanism 3 includes two sliders 301. The inner walls of the two sliders 301 are slidably connected to the inner walls of the two carriages 2, and can slide along the inner walls of the carriages to adjust the position. The inner walls of the two sliders 301 are threaded with locking knobs 302, which can fix or loosen the sliders 301 to lock the adjusted position. The outer walls of the two sliders 301 are fixedly connected to the same plate frame 303 on adjacent sides, which is used to install subsequent components and move with the sliders 301. The inner wall of the plate frame 303 is slidably connected with a baffle 304, which can move up and down to block or release the cardboard. A lifting component 305 is provided on the right side of the baffle 304. A knife holder component 306 is provided on the top of the cutting table 4. A cutting component 307 is provided on the top of the machine tool 1.

[0035] The lifting assembly 305 includes a stepper motor 3051, the bottom of which is fixedly connected to the top of the plate frame 303, providing a power source for the lifting assembly 305 and enabling power output control. A slide plate 3052 is fixedly connected to the output end of the stepper motor 3051, converting the power of the stepper motor 3051 into linear motion of the slide plate 3052. Multiple push rods 3053 are rotatably connected to the top of the slide plate 3052, pushing the baffle 304 up and down by changing its angle, thus achieving longitudinal positioning of the cardboard. The knife holder assembly 306 includes two mounting brackets 3061. The bottom of each mounting bracket 3061 is fixedly connected to the front and rear sides of the top of the machine tool 1, providing a stable mounting base for the tool rail 3062. The same tool rail 3062 is fixedly connected to the adjacent side of the outer wall of the two tool holder assemblies 306, providing a movement track for the cutting blade 3072 and ensuring the accuracy of the cutting path. The cutting assembly 307 includes a telescopic rod 3071. The outer wall of the telescopic rod 3071 is fixedly connected to the outer wall of the rear mounting bracket 3061, providing telescopic power for the movement of the cutting blade 3072. The cutting blade 3072 is fixedly connected to the front end of the telescopic rod 3071 to perform cutting operations on the positioned cardboard, realizing the cutting function of the equipment.

[0036] Specifically, during operation, each mechanism executes its operation sequentially to cut the cardboard. Before starting, the adjusting mechanism 3 is adjusted by rotating the locking knob 302 to adjust the position of the slider 301 fitted onto the slide 2, thereby moving the plate frame 303 and adjusting the lateral position of the adjusting mechanism 3 to position cardboard of different lengths. After the equipment starts, the conveyor belt 602 of the transport mechanism 6 operates, transporting the cardboard to the processing area. When the front end of the cardboard enters the sensing range of the distance sensor 8, the sensor feeds back the position signal to the control system. At this time, the lifting assembly 305 responds. Upon receiving the instruction, stepper motor 3051 drives slide plate 3052 forward, causing push rod 3053 to change angle and pull baffle 304 down to contact conveyor belt 602, achieving longitudinal positioning of the cardboard. After positioning, telescopic rod 3071 of cutting assembly 307 extends, driving cutting blade 3072 to move along blade rail 3062, completing cutting under the support of cutting table 4. After cutting, stepper motor 3051 pushes slide plate 3052 backward, push rod 3053 lifts baffle 304, and conveyor belt 602 restarts, transporting the finished cardboard to the next process.

[0037] See attached document Figure 2 and attached Figure 5The collection mechanism 5 includes a support 501. The bottom of the support 501 is fixedly connected to the bottom of the inner wall of the machine tool 1, providing a stable installation foundation and support for the collection mechanism 5. A filter box 502 is slidably connected to the inner wall of the support 501, which facilitates disassembly and cleaning of the collected waste debris. The bottom of the support 501 is connected to an air duct 503, which serves as a waste debris transmission channel. A fan 504 is fixedly connected to the inner wall of the air duct 503, which generates suction to draw the waste debris into the air duct 503. A chip collection component 505 is installed inside the air duct 503 to perform secondary collection and processing of the waste debris.

[0038] Specifically, during the cardboard cutting process, the collection mechanism 5 collects and processes waste and debris. The bottom of the support 501 is fixed to the bottom of the inner wall of the machine tool 1 to provide support for the collection mechanism 5. Its inner wall slide is slidably connected to the filter box 502 for easy cleaning. When the cutting component 307 is working, the fan 504 fixed to the inner wall of the air duct 503 is started. Through the air duct 503 connected to the support 501, waste and debris from the surface and surrounding area of ​​the cutting table 4 are sucked in. The waste is first intercepted by the filter box 502 to intercept large debris, and the small debris enters the chip collection component 505 for secondary processing. After the filter box 502 is full, the operator pulls it out along the slide to clean it. After reinstallation, the collection mechanism 5 continues to operate and the equipment is kept clean.

[0039] See attached document Figure 1 Appendix Figure 2 and attached Figure 5 The transport mechanism 6 includes two servo motors 601, the bottoms of which are fixedly connected to the bottom left and right sides of the inner wall of the machine tool 1, respectively, to provide power for the operation of the conveyor belt 602. Two conveyor belts 602 are slidably connected to the inner wall of the machine tool 1 to carry and transport the cardboard to be cut. The chip collection assembly 505 includes a dust baffle 5051, the outer wall of which is fixedly connected to the inner wall of the air duct 503 to block and guide waste chips and prevent them from splashing. A chip collection tray 5052 is slidably connected to the bottom of the inner wall of the air duct 503 to facilitate the centralized collection of waste chips and to facilitate removal and cleaning. Two limit plates 7 are rotatably connected to the top left side of the machine tool 1, which can adjust the angle to limit the transport position of the cardboard and ensure that the cardboard is transported along the predetermined path.

[0040] Specifically, the transport mechanism 6 drives the conveyor belt 602 through servo motors 601 fixed to the bottom of the inner wall of the machine tool 1 on both sides, achieving stable and precise cardboard conveying. Two limit plates 7 are rotatably installed on the top left side of the machine tool 1, and the angle can be adjusted to limit the cardboard, helping to ensure the accuracy of the cardboard transport path. In the chip collection assembly 505, the dust baffle 5051 is fixed to the inner wall of the air duct 503, which can block and guide the sucked-in waste chips. Together with the chip collection tray 5052 at the bottom of the inner wall of the air duct 503, it is convenient to collect waste materials in a concentrated manner, and the operation of pulling out and cleaning is convenient, effectively avoiding chip residue, keeping the working environment of the equipment clean, and improving the overall operating efficiency.

[0041] Working principle: Before the equipment starts, the adjusting mechanism 3 is activated to position the cardboard. In the adjusting mechanism 3, two sliders 301 are mounted on the slide 2. By tightening or loosening the locking knob 302, the position of the sliders 301 on the slide 2 can be fixed or adjusted, thereby changing the lateral position of the entire adjusting mechanism 3 to adapt to the positioning requirements of cardboard of different lengths. After the equipment starts, the transport mechanism 6 operates first, and the conveyor belt 602 transports the cardboard to be cut to the processing area of ​​the equipment. The cardboard moves along the conveyor belt 602. When the front end of the cardboard moves into the sensing range of the distance sensor 8, the distance sensor 8 monitors the position of the cardboard in real time. When the position of the slider 301 is determined, the board frame 303 is fixed by the slider 301. Subsequently, the lifting assembly 305 starts to work, the stepper motor 3051 starts, and its output end drives the slide plate 3052 to move forward. The top of the slide plate 3052 rotates and is connected to multiple pushers. The lever 3053 changes its angle and pulls the baffle 304 downward. At this time, the baffle 304 descends to contact the surface of the conveyor belt 602, forming a blockage and stopping the paperboard being transported at the designated position, thus completing the longitudinal positioning of the paperboard. After the paperboard is positioned, the cutting assembly 307 begins to perform the cutting task. The telescopic lever 3071 in the cutting assembly 307 extends forward, driving the cutting blade 3072 at the front end to move quickly along the blade rail 3062. The cutting table 4 serves as a support plane, providing stable force support for the paperboard and ensuring the cutting quality. After the cutting is completed, the control system controls the stepper motor 3051 to operate again, causing it to push the slide plate 3052 backward. The push rod 3053 rotates in the opposite direction, pushing the baffle 304 upward and causing it to detach from the surface of the conveyor belt 602. At this time, the conveyor belt 602 of the transport mechanism 6 restarts and transports the cut paperboard to the next processing point.

[0042] Furthermore, the waste and debris generated during the cardboard cutting process are collected by the collection mechanism 5 at the bottom of the cutting table 4. The bottom of the bracket 501 is firmly fixed to the bottom of the inner wall of the machine tool 1, forming a stable base for the collection mechanism 5. Its inner wall is provided with a slide rail that is slidably connected to the filter box 502, providing a pull-out track for the filter box 502 for easy cleaning later. When the cutting component 307 cuts the cardboard, the fan 504 is fixed to the inner wall of the air duct 503 and starts running synchronously. The fan 504 generates a strong suction force, which, through the air duct 503 connected to the bottom of the bracket 501, removes the waste from the surface and surrounding area of ​​the cutting table 4. Debris is rapidly sucked in, and the sucked-in waste debris first passes through the filter box 502 located above the air duct 503. Large debris is initially intercepted by the filter box 502, while small debris continues to enter the debris collection assembly 505 through the air duct 503 for secondary processing. As the cutting work continues, the filter box 502 continuously collects waste. When the filter box 502 is full, the operator pulls it out along the slide on the inner wall of the bracket 501, cleans the waste in the box, and reinstalls it in place to ensure that the collection mechanism 5 continues to operate efficiently, removes cutting waste in a timely manner, maintains a clean working environment for the equipment, and avoids debris accumulation that may affect the normal operation of the equipment.
