Description

Technical Field

[0001] The present application relates to the field of corrugated paper production, and particularly to a creasing machine for corrugated paper production. Background Art

[0002] Most corrugated papers are composed of two categories: single corrugated cardboard and double corrugated cardboard. The board-shaped object formed by bonding the corrugated paper with a waveform formed by processing the facing paper through a corrugating roll is usually called corrugated paper, and the combination of multiple corrugated papers is collectively called a corrugated cardboard box.

[0003] When processing corrugated cardboard boxes, a creasing machine is usually required to make creases, so as to achieve the purpose of convenient folding. When the common creasing machine is in use, since most corrugated papers are in a fixed state, when making creases, due to the downward force, the corrugated paper may move closer to the center, thus causing damage to the corrugated paper. Due to the appearance of indentations in the middle of the corrugated paper, the corrugated paper may also break, resulting in unnecessary losses.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

On the opposite sides of the plurality of L-shaped connecting plates, a plurality of connecting seats are fixedly connected. The lower surface of the base is rotatably connected with two placing plates through the plurality of connecting seats. On both sides of the lower surface of the placing plate, mounting seats are fixedly connected. On one side of the inner wall of the mounting seat, a rotating block is rotatably connected.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will further describe the present application in detail Figures 1-4 with reference to the accompanying drawings.

[0020] The embodiment of the present application discloses a creasing machine for corrugated paper production. Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, A creasing machine for corrugated paper production, including a base 1. On both sides of the upper surface of the base 1, a number of L-shaped connecting plates 10 are fixedly connected. On the opposite sides of a number of L-shaped connecting plates 10, a number of connecting seats 17 are fixedly connected. The lower surface of the base 1 is rotatably connected with two placing plates 9 through a number of connecting seats 17. The placing plates 9 are connected to the L-shaped connecting plates 10 through the connecting seats 17, and the connecting seats 17 are rotatably connected to the placing plates 9. Then, one end of the placing plate 9 can rotate. On both sides of the lower surface of the placing plate 9, mounting seats 15 are fixedly connected. On one side of the inner wall of each mounting seat 15, a rotating block 14 is rotatably connected. On the upper surface of the base 1, corresponding to one side of each rotating block 14, a spring rod 16 is fixedly connected. The telescopic ends of the spring rods 16 are connected to the rotating blocks 14. Through the connection between the rotating blocks 14 and the mounting seats 15, and the rotating blocks 14 are connected to the bottom of the placing plates 9. Through the connection between the telescopic ends of the spring rods 16 and the rotating blocks 14, a part of the spring rods 16 is buried inside the base 1. When the opposite sides of the two placing plates 9 are squeezed, it drives the opposite sides of the two placing plates 9 to rotate downward simultaneously. When an external force acts on the spring rods 16, the internal springs will produce elastic deformation, so that when the corrugated paper placed on the tops of the two placing plates 9 is creased, the central area will sink downward, which can avoid the cardboard from cracking. But after the external force disappears, the spring rods 16 will return to their original state, thus pushing the placing plates 9 to reset, achieving the effect of being able to avoid cracking when the corrugated paper is creased.

[0021] Refer to Figure 1 , Figure 2 , Figure 3 And Figure 4 , On one side of the upper surface of each placing plate 9, a fixed plate 8 is fixedly connected. On one side of the upper surface of each fixed plate 8, an electric telescopic rod 11 is fixedly connected. The telescopic ends of the electric telescopic rods 11 all penetrate through the inner wall of the fixed plate 8 and are fixedly connected with a pressing plate 13. By installing the electric telescopic rods 11 on the tops of the fixed plates 8 and connecting the electric telescopic rods 11 with the pressing plates 13, then the pressing plates 13 are driven to move downward simultaneously by the electric telescopic rods 11 on both sides to fix the two ends of the corrugated paper, thus achieving the effect of being able to avoid the corrugated cardboard from skewing and ensuring a more ideal creasing effect on the corrugated cardboard.

[0022] Refer to Figure 1 And Figure 2, on one side of the upper surface of the base 1, there is a fixedly connected connecting frame 2. On both sides of the inner wall of the connecting frame 2, vertical grooves 7 are provided. On one side of the interior of each vertical groove 7, there is a slidably connected slider 4. Since the size of the slider 4 fits the size of the vertical groove 7, the slider 4 can move up and down along the inner wall of the vertical groove 7. On one side of the upper surface of the connecting frame 2, there is a fixedly connected hydraulic rod 3. The telescopic end of the hydraulic rod 3 extends into the interior of the connecting frame 2. The upper surface of the base 1 is connected with an installation plate 5 through the hydraulic rod 3, two sliders 4 and two vertical grooves 7 for lifting. Because a hydraulic system is formed by a hydraulic cylinder, a reversing valve, an oil pump, and an oil tank, when the reversing valve on the outer wall of the hydraulic cylinder is in the forward direction, the oil in the oil tank is transported into the hydraulic cylinder along the two hoses by the oil pump, so as to push the telescopic rod in the hydraulic cylinder, and then the hydraulic rod 3 drives the installation plate 5 to descend under the restriction of the two sliders 4 on both sides. By setting the reversing valve to the reverse direction, the oil pump sucks the oil in the hydraulic cylinder back into the oil tank, and then the hydraulic rod 3 drives the installation plate 5 to rise. Thus, the hydraulic rod 3 drives the installation plate 5 to lift. On one side of the lower surface of the installation plate 5, there is a fixedly connected creasing plate 6. By installing the creasing plate 6 at the bottom of the installation plate 5, when the installation plate 5 moves downward, it drives the creasing plate 6 to indent the corrugated paper. On one side of the upper surface of the base 1, corresponding to one side of the creasing plate 6, there is a creasing groove 12. Through the creasing groove 12 opened at the top of the base 1, when the creasing plate 6 is forced to descend, it can just move into the creasing groove 12, avoiding damage to the creasing plate 6.

[0023] The implementation principle of a creasing machine for corrugated paper production in an embodiment of the present application is as follows: when creasing corrugated paper, first, place the corrugated paper on the tops of two placing plates 9. Install the electric telescopic rod 11 on the top of the fixing plate 8 and connect the electric telescopic rod 11 with the pressing plate 13. Then, drive the pressing plate 13 to move downward simultaneously by the two electric telescopic rods 11 on both sides to fix both ends of the corrugated paper. Subsequently, drive the installation plate 5 to move downward by the hydraulic rod 3, and drive the creasing plate 6 to indent the corrugated paper. When creasing the corrugated paper, the relative sides of the two placing plates 9 are subjected to pressure and rotate downward simultaneously, forming a "V" shape for the two placing plates 9, and the central area of the corrugated paper sinks downward, which can avoid the cardboard from cracking. After the external force disappears, the spring rod 16 will return to its original shape, thereby pushing the placing plate 9 to reset.
