The cardboard box to be processed is placed into a working box made of transparent acrylic material through a feeding groove. A conveyor belt is provided at the bottom of the box for convenient transportation. The fixture automatically clamps and fixes the cardboard box. The cutting mechanism first performs positioning and cutting, and the electric cylinder drives the cutting knife to move down to complete the cutting. After cutting, the electric push rod pushes the folding plate to fold and form the cardboard box. The horizontal position of the cutting knife is adjusted by the driving component.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 8 shown, the present invention provides a carton folding device for carton processing, including a working box 1. Feeding chutes 11 are opened on both sides of the working box 1. The feeding chutes 11 are used for feeding the cartons to be processed. A discharging chute 12 is opened at the bottom of the working box 1; Fixture 2, the fixture 2 is arranged inside the working box 1, and the fixture 2 is used for clamping the cartons to be processed; Folding plate 3, the folding plate 3 contacts the carton to be processed and is used to push it to fold. Two symmetric electric push rods 31 are fixedly arranged on the folding plate 3, and the electric push rods 31 are fixedly connected to the inner wall of the working box 1; Cutting mechanism 4, the cutting mechanism 4 is located on the side of the working box 1 away from the fixture 2, and the cutting mechanism 4 is used for cutting and positioning the cartons to be processed.

[0023] Adopt the above solution: Place the cardboard box to be processed along the feeding chute 11 inside the working box 1, and use the fixture 2 to clamp and fix it. The center of the bottom of the working box 1 is in the form of a conveyor belt, and the working box 1 is made of transparent acrylic material, which is convenient for users to observe. After placing, use the cutting mechanism 4 to position and cut the cardboard box to be processed first. Specifically, the electric cylinder 43 drives the mounting plate 42 and the cutting knife 41 to move down close to the cardboard box to be processed to achieve rapid cutting. After this cutting is completed, the folding plate 3 is driven by the electric push rod 31 to push and fold the cut cardboard box, thus completing the whole operation.

[0024] As Figure 4 shown, the cutting mechanism 4 includes a cutting knife 41, a mounting plate 42 fixedly arranged on the top of the cutting knife 41, two electric cylinders 43 fixedly arranged on the symmetric two sides of the top of the mounting plate 42, a connecting plate 44 fixedly installed on the top of the electric cylinder 43, and a driving component 45 arranged on the top of the connecting plate 44. The driving component 45 is used to drive the position adjustment of the cutting knife 41.

[0025] The driving component 45 includes a slider 451 fixedly arranged on the top of the connecting plate 44, a screw rod 452 screwed on the slider 451, a motor 453 fixedly installed at one end of the screw rod 452 and fixedly connected with the side wall of the working box 1, and a guide rod 454 fixedly arranged inside the working box 1. The slider 451 slides along the guide rod 454, and the screw rod 452 is rotatably connected with the two sides of the working box 1.

[0026] Adopt the above solution: The driving component 45 is used to realize the horizontal movement of the cutting knife 41, so that it slides along the blanking chute 12. The measurement component 46 is used for measurement in cooperation. After the measurement is completed, the motor 453 drives the screw rod 452 to rotate, and then drives the slider 451 to slide along the guide rod 454 to realize the movement adjustment within the range of the blanking chute 12. After the adjustment is completed, the motor 453 stops running. At this time, the electric cylinder 43 drives the cutting knife 41 to move down for precise cutting.

[0027] As Figure 8 shown, a measurement component 46 is arranged on the side of the bottom of the mounting plate 42 away from the cutting knife 41. The measurement component 46 is used to measure the cardboard box to be processed; The measurement component 46 includes a measurement plate 461, a connecting frame 462 fixedly arranged on the top of the measurement plate 461, and a plurality of springs 463 fixedly installed on the top of a plurality of connecting frames 462 and arranged in a linear array. The plurality of springs 463 are fixedly connected with the bottom of the mounting plate 42. A scale is arranged on the surface of the measurement plate 461. The connecting frame 462 is in a U shape and is fixedly connected with the measurement plate 461 on both sides.

[0028] Adopting the above solution: The measurement of the edge of the cardboard box to be processed is realized by the measuring component 46, enabling more precise cutting. The connecting frame 462 is pushed downward by the spring 463, thereby driving the measuring plate 461 to move downward to approach the cardboard box to be processed and measure its edge dimensions, and cutting the excess cardboard box to make the processing more precise.

[0029] As Figure 6 shown, the bottom of the cutting knife 41 is close to the blanking chute 12, and a cleaning component 47 is arranged at the top of the blanking chute 12. The cleaning component 47 is used to pour the cardboard debris generated by cutting into the bottom blanking chute 12. The cleaning component 47 includes a pushing block 471, a toothed plate 472 fixedly arranged at the top of the pushing block 471, a gear 473 meshing with the toothed plate 472, a driving rod rotatably arranged at the center of the gear 473, two support plates 474 fixedly arranged at both ends of the driving rod and fixedly connected to the bottom of the working box 1. A rack meshing with it is fixedly arranged on one side of the cutting knife 41 close to the gear 473. A through groove 421 is opened at the top of the mounting plate 42. The toothed plate 472 slides along the through groove 421. A limiting plate 4721 is fixedly arranged at the top of the toothed plate 472. Tooth teeth 475 are fixedly arranged on the mutually remote sides of the toothed plate 472. A cross bar 476 is clamped on the side of the tooth teeth 475 close to the gear 473. A spring rod 477 is fixedly installed on the side of the cross bar 476 away from the tooth teeth 475. The spring rod 477 is fixedly connected to the driving rod.

[0030] Adopting the above solution: The excess cardboard box edges generated by cutting are quickly exported and cleaned through the cleaning component 47. After cutting is completed, the electric cylinder 43 drives the cutting knife 41 to move upward, and the rack on the cutting knife 41 moves upward synchronously, thereby driving the gear 473 to rotate. When the gear 473 meshes with the toothed plate 472 and rotates, it drives the toothed plate 472 to move downward, thereby driving the pushing block 471 to move downward to squeeze the excess cardboard box edges after cutting, so that one side is pressed and falls along the blanking chute 12 for discharge. When cutting is required, the electric cylinder 43 drives the cutting knife 41 to move downward. At this time, it can drive the gear 473 to rotate in the reverse direction, driving the toothed plate 472 to move upward, so that the pushing block 471 moves upward synchronously away from the cardboard box to be processed to avoid affecting its cutting. Among them, the tooth teeth 475 are clamped with the cross bar 476. When the toothed plate 472 moves upward, the cross bar 476 squeezes the spring rod 477 to make it away from the tooth teeth 475. When it moves downward under gravity, the cross bar 476 blocks the tooth teeth 475 to prevent it from moving downward, thereby achieving the limiting effect.

[0031] Working principle and usage process of the present invention: When using this carton processing device, the operator first smoothly pours the carton to be processed into the interior of the working box 1 through the inclined feed chute 11. Driven by the transmission system, the carton moves orderly along the conveyor belt in the working box 1 until it is accurately conveyed to the station of the fixture 2. At this time, the clamping mechanism of the fixture 2 will be quickly activated to firmly fix the carton in the processing position, ensuring the stability of the subsequent processing process. After the fixation is completed, the measurement component 46 starts to work. Its measurement plate 461 will accurately approach the surface of the carton, and through contact or non-contact measurement methods, comprehensively collect the size data of the carton, providing accurate parameter basis for the subsequent cutting process. After the measurement data is fed back to the control system, the driving component 45 will automatically adjust the position of the cutting knife 41 according to the preset program to accurately position it within the effective range of the discharge chute 12. After the positioning is completed, the electric cylinder 43 drives the cutting knife 41 to quickly move downwards, and precisely cuts the carton with a stable pressure and speed, ensuring that the cut is smooth and the edge is precise, fully meeting the strict requirements of the subsequent assembly process. During the cutting process, the pushing block 471 will retract synchronously to avoid the processing area, while the measurement plate 461 remains in contact with the carton to monitor the processing quality in real time. When the cutting process is completed, the cutting knife 41 quickly resets and rises under the drive of the electric cylinder 43. At this time, the pushing block 471 immediately presses down, and discharges the waste generated by cutting from the discharge chute 12 efficiently through mechanical thrust, realizing the automatic waste removal function. The entire processing process realizes the intelligent linkage of measurement, positioning, cutting and waste removal, not only greatly improving the processing accuracy and production efficiency, but also ensuring the safety and stability of the operation process.
