Description

Technical Field

[0001] The utility model relates to the technical field of carton folding and forming devices, in particular to a corrugated carton folding and forming device. Background Art

[0002] Traditional carton production usually includes the following process flow: sheet loading, paper feeding, offset printing, denting, and slotting. Later, new automated carton production equipment has emerged, which includes the following process flow: sheet loading, paper feeding, offset printing, denting, slotting, folding, gluing (or stapling), and packaging.

[0003] After the cartons are grooved, they need to be manually folded according to the indentations and grooves of the corrugated paper. The folded corrugated paper is then collected, stacked, and fed into a stapler for stapling. This not only greatly increases labor costs but also easily causes uneven quality of the folded cartons. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5As shown, a corrugated cardboard box folding and forming device includes a conveyor belt 1 for conveying the indented corrugated cardboard. One end of the conveyor belt 1 is aligned with the top ends of two frames 2, so that the conveyor belt 1 can transport the corrugated cardboard to the top ends of the frames 2. Wheels are provided at the bottom ends of the frames 2 to allow the frames 2 to be adjusted in position. A folding mechanism 3 is provided within the frames 2 for folding the corrugated cardboard. A pressing mechanism 4 is provided between the top ends of the two frames 2 for pressing the indentations on the corrugated cardboard so that the corrugated cardboard can enter the folding mechanism 3 for folding and forming.

[0024] In this embodiment, the folding mechanism 3 includes a turret 31 rotatably mounted on one side of the frame 2 at a top position, allowing for adjustable angles. Multiple rotating rods 32 are rotatably mounted within the turret 31 for transporting the corrugated cardboard. The two turrets 31 form a V-shaped structure, allowing for synchronous movement of both sides of the corrugated cardboard, thereby folding the cardboard more stably.

[0025] In this embodiment, a driving gear 34 is provided at the connection between the frame 2 and the turret 31. This driving gear 34 is driven by a motor. The driving gear 34 is meshed with a driven gear 33. A transmission belt 35 is connected between adjacent rotating rods 32. This allows the motor to drive all rotating rods 32 to rotate synchronously and in the same direction, thereby conveying corrugated cardboard downward along the angle of the turret 31.

[0026] In this embodiment, a movable groove 36 is fixedly installed on the rotating frame 31, and a cylinder 37 is fixedly installed on the frame 2. The cylinder 37 is slidingly connected to the movable groove 36. The piston rod of the cylinder 37 can be extended and retracted to adjust the angle of the rotating frame 31. The movable groove 36 is used to compensate for the movement stroke of the piston rod of the cylinder 37.

[0027] In this embodiment, a clamping plate 38 is rotatably mounted at the bottom end of the rotating frame 31. This clamping plate 38 is used to secure the folded corrugated cardboard and prevent it from rebounding and causing disorganization. A telescopic rod 39 is connected between the clamping plate 38 and the frame 2. One end of the telescopic rod 39 is fixedly connected to the frame 2, and the other end is slidably connected to the clamping plate 38. The telescopic rod 39 is preferably a spring-loaded sleeve that provides clamping force to the clamping plate 38 without damaging the corrugated cardboard.

[0028] In this embodiment, the pressing mechanism 4 includes a pull rod 43, the top end of which is detachably connected to a pressing rod 44, preferably by a snap connection or a threaded connection. A pressing wheel 45 is fixedly mounted on the pressing rod 44 and is used to align the corrugated cardboard with the indentation, preventing the cardboard from folding inaccurately when pressed, thereby improving bending accuracy.

[0029] In this embodiment, a slide groove 41 is opened at the top of the frame 2, and a pull rod 43 is slidably installed in the slide groove 41. The pull rod 43 and the slide groove 41 are connected by a tension spring 42. The tension spring 42 provides downward pressure to the pull rod 43, so that the corrugated cardboard is bent downward at a certain angle along the indentation.

[0030] It should be noted that the present invention is a corrugated cardboard folding and forming device. When in use, the corrugated cardboard is indented by the indentation device and then transmitted to the top of the frame 2 through the conveyor belt 1. By changing the position of the fixed clamping rod 44, the clamping wheel 45 can be aligned with the indentation driven by the folding. When the corrugated cardboard enters the frame 2, the clamping wheel 45 will move upward. After the corrugated cardboard completely enters the top of the frame 2, under the action of the tension of the tension spring 42, the pull rod 43 is pulled downward along the slide groove 41, so that the clamping wheel 45 presses the indentation of the corrugated cardboard downward, causing the corrugated cardboard to bend downward at a certain angle, thereby causing the corrugated cardboard to contact the rotating rod 32.

[0031] Start the motor, the motor drives the driving gear 34 to rotate, and then drives the driven gear 33 to rotate through meshing action, and the driven gear 33 drives the rotating rod 32 to rotate. The rotating rods 32 are driven by the transmission belt 35, so that the rotating rods 32 rotate synchronously, thereby driving the two sides of the corrugated cardboard to move downward along the V shape, so that it is folded.

[0032] After the corrugated cardboard is folded, the two clamping plates 38 are squeezed apart and moved downward under the drive of the lowest rotating rod 32. The elastic force of the telescopic rod 39 causes the clamping plates 38 to squeeze the folded corrugated cardboard, thereby reducing the rebound of the corrugated cardboard after folding.

[0033] To cope with different types of corrugated cardboard, the two frames 2 can be adjusted in position by wheels, thereby adjusting the relative width of the top of the frames 2 to improve adaptability. At the same time, the angle of the rotating frame 31 can be adjusted by the expansion and contraction of the cylinder 37 to adapt to different widths of corrugated cardboard.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
