Description

Technical Field

[0001] This utility model relates to the field of cardboard processing technology, and more specifically, to a cardboard cutting device. Background Technology

[0002] Paperboard is a thick sheet of paper made from various pulps, composed of interwoven fibers. The difference between paperboard and regular paper is usually distinguished by basis weight and thickness; generally, paperboard with a basis weight exceeding 250 g / m³ is considered superior. 2 Paperboard is defined as having a thickness greater than 0.5mm. After production, paperboard is usually a large, integral structure that requires a cutting device to cut the entire sheet of paperboard into blocks.

[0003] Patent CN213533976U discloses a cardboard cutting mechanism that reduces the loading and unloading height of cardboard through a liftable cutting table, saving time and labor. The cutting table rises to cut the cardboard, eliminating the need for the cutting blade to move up and down, thus reducing safety hazards for operators. An edge trimming mechanism can trim the edges of the cardboard, improving work efficiency. However, this cutting mechanism cannot adjust the cutting position during use, only cutting in one direction, which limits its application. Furthermore, the cardboard is prone to shifting during cutting, resulting in misaligned cuts and affecting the cutting quality. Utility Model Content

A cutting blade 7 is provided on the inner top surface of the mounting frame 2. A support platform 3 is provided on the inner side of the mounting frame 2. A turntable 4 is rotatably connected to the upper surface of the support platform 3. A placement platform 5 is slidably connected to the upper surface of the turntable 4. Positioning mechanisms 6 are provided on both sides of the placement platform 5. An electric telescopic rod 64 is provided on the opposite side of the two positioning mechanisms 6. The output end of the electric telescopic rod 64 is fixedly connected to the positioning mechanism 6. The turntable 4 rotates, causing the placement platform 5 to rotate, which in turn rotates the cardboard, thereby adjusting the angle of the cardboard and achieving transverse cutting of the cardboard (see reference). Figure 4 ) and vertical cutting (see Figure 5 This design allows for various cutting needs. Furthermore, the placement table 5 is slidably connected to the turntable 4. During the cutting process, the placement table 5 can be moved to change the cutting position of the cutting blade on the cardboard, allowing the cutting blade to perform multi-segment cutting along the direction of movement of the placement table, thus improving the practicality of the device. The electric telescopic rod 64 drives the positioning mechanism 6 to move, thereby fixing the cardboard and preventing it from shifting during the cutting process, improving the cutting quality.

[0032] In this embodiment, a motor 9 is provided on the surface of the base 1, and the output end of the motor 9 passes through the support platform 3 and is fixedly connected to the turntable 4. The motor 9 drives the turntable 4 to rotate, which is convenient to operate and can speed up the cardboard cutting process.

[0033] In this embodiment, the positioning mechanism 6 includes a buffer seat 61 and a limiting plate 62. The buffer seat 61 has a groove 611 on its inner side, and the groove 611 is connected to the limiting plate 62 by a spring 612. The limiting plate 62, the buffer seat 61, and the spring 612 work together to disperse the pressure on the cardboard, reduce the rigid compression of the cardboard, and prevent the cardboard from being squeezed and deformed.

[0034] In this embodiment, the inner side of the limiting plate 62 is provided with a second groove 621, and a plurality of rollers 63 are evenly distributed inside the second groove 621. The outer circumferential surface of the rollers 63 contacts the cardboard. The rollers 63 are mounted inside the second groove 621 via a rotating shaft. The rollers 63 are made of flexible materials, such as rubber and foam, which can further reduce the rigid compression on the cardboard.

[0035] In this embodiment, the placement platform 5 is provided with a baffle 10 at its edge, and the baffle 10 is perpendicular to the limiting plate 62. The baffle 10 can prevent the cardboard stacked on the surface of the placement platform 5 from falling off.

[0036] In this embodiment, the baffle 10 is engaged with the placement table 5. The detachable design of the baffle 10 facilitates the unloading of the cut cardboard from the placement table 5. When unloading, the baffle 10 is removed, and the cardboard is pushed out of the table surface of the placement table 5.

[0037] In this embodiment, the upper surface of the turntable 4 is provided with a groove 41, and the lower surface of the placement platform 5 is provided with a slider 51, the slider 51 being adapted to the groove 41.

[0038] In this embodiment, the mounting frame 2 is equipped with a cylinder 8 at its top. The output end of the cylinder 8 passes through the mounting frame 2 and is fixedly connected to the cutting blade 7. The cylinder 8 drives the cutting blade 7 to descend, so as to cut the cardboard on the surface of the placement table 5. It can cut a single piece of cardboard or multiple pieces of cardboard.

[0039] The working principle of a cardboard cutting device is as follows: Cardboard is placed on the platform 5, with one side of the cardboard abutting against the baffle 10. An electric telescopic rod 64 moves the buffer seat 61, simultaneously moving the limiting plate 62, causing the limiting plates 62 on both sides of the platform 5 to move closer together, so that the outer circumference of the roller 63 abuts against the side of the cardboard. A cylinder 8 drives the cutting blade 7 to descend, and the cutting blade 7 cuts the cardboard on the surface of the platform 5, completing the cutting process.

[0040] When it is necessary to cut the cardboard into multiple segments along the direction of the placement table 5, the cylinder 8 drives the cutting blade 7 to rise, moves the placement table 5, adjusts the position of the placement table 5 on the turntable 4, and then the cylinder 8 drives the cutting blade 7 to cut again. The above operation is repeated to achieve multi-segment cutting of the cardboard.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
