Description

Technical Field

[0001] The present invention relates to the technical field of corrugated paper cutting, and specifically provides a feeding and cutting device for corrugated paper production. Background Art

[0002] Corrugated board is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. The actual performance of corrugated board depends on three factors: the characteristics of the core paper and cardboard, and the structure of the carton itself. For the cutting and creasing operations of corrugated board, the most notable points are the cutting edge quality and the appropriate crease. Both are related to the water content of the cardboard itself. When the water content is between 10% - 13%, the cardboard has good stiffness, and a sharp cutting edge can cut out neat and straight edges. If the water content exceeds 13%, the stiffness of the corrugated board will drop sharply, the cutting edge will become ragged, and even the so-called "closed mouth" failure will occur, that is, the edge of the cardboard is flattened, and the top of the corrugated paper is crushed. The closed mouth failure not only affects the appearance of the carton, but also greatly reduces the thickness of the cardboard edge. If the water content of the corrugated board is too small, the paper fibers will become brittle, ultimately resulting in unclear creases or crease line breakage. In addition, the installation position of the concave and convex creasing rollers should be carefully calibrated. Even a slight deviation in the position will cause the corrugated board to break.

[0003] In the existing corrugated paper cutting equipment, due to structural design defects, there are problems of how to prevent the corrugated board from cracking during cutting due to the movement of the pressure wheel position, and how to prevent the edge of the corrugated board from being flattened to produce closed mouth defects during cutting.

[0010] Preferably, a pressure wheel is magnetically connected to the surface of the shaft body near the magnetic ring. A rubber roller is fixedly connected to the surface of the shaft body. The surface of the rubber roller is slidably connected to the inner side of the pressure wheel.

[0011] Preferably, the anti - flattening mechanism includes a sliding table. The bottom of the sliding table is fixedly connected to the top of the driving device.

[0016] The present invention provides a feeding and cutting device for corrugated paper production. It has the following beneficial effects:

[0017] 1. For the feeding and cutting device for corrugated paper production, the partition plates make there be gaps between the gear belts, drive the device to adjust the position of the support plate through the threaded rod, the indentation component presses and indents the upper position of the corrugated paper board, the corrugated paper board is conveyed to the anti-flattening mechanism for cutting, and the anti-deviation component limits the side edges of the stacked corrugated paper boards, solving the problem of how to prevent the corrugated paper board from cracking during cutting due to the movement of the pressing wheel position.

[0018] 2. For the feeding and cutting device for corrugated paper production, the device is provided with two rubber rollers. By driving the device to adjust the positions of the rubber rollers, one rubber roller is far away from the anti-flattening mechanism, and the other is arranged close to the anti-flattening mechanism. The two rubber rollers press and limit the corrugated paper. The motor drives the rubber rollers to rotate. At the same time, the corrugated paper is conveyed by the gear belt. The extension plate and the support table limit the rotating roller at the side position of the corrugated paper board. As the corrugated paper is conveyed, the rotating roller rotates, which can prevent the corrugated paper from shifting and cracking.

[0019] 3. For the feeding and cutting device for corrugated paper production, the stacked corrugated paper boards are conveyed to the position of the cutting knife. The cutting knife is arranged at the gap position of the gear belt. The boosting component makes the cutting knife reciprocate, and the limiting component limits the lower position of the cutting knife, so as to cut the stacked corrugated paper boards. When the prior art directly presses and cuts the stacked and relatively thick corrugated paper boards, it is easy to flatten the surface of the corrugated paper board. This device solves the problem of how to prevent the edge of the corrugated paper board from being flattened and generating a closed mouth defect during cutting.

[0020] 4. The feeding and cutting equipment for corrugated paper production has slots on the surface of the cylinder body. These slots prevent direct contact between the cylinder body and the connecting rod. An elastic strip is used to separate the cylinder body and the connecting rod. When the cutting knife moves up or down, the elastic strip converts the rigidity into flexible resilience. The bottom end of the cutting knife is rotatably connected to the surface of the cylinder body through a ball hinge, effectively reducing the rigid impact between the cutting knife and the cylinder body.

[0021] 5. In the feeding and cutting equipment for corrugated paper production, the pressure wheel is connected to the shaft body by magnetism. The rubber roller can prevent the pressure wheel from shifting when making indentations on the corrugated cardboard. The elastic strip is arranged between the cylinder body and the connecting rod. Subsequently, the oil pump relieves pressure, and the hydraulic oil is squeezed out of the cylinder body by the spring, pushing the cutting knife to move upward a certain distance. As the hydraulic oil is pressurized and depressurized, the cutting knife reciprocates, thus cutting the indented position of the corrugated cardboard without causing deviation problems.

This device solves the problem of how to prevent the edge of the cardboard from being flattened and generating a closed mouth defect during cutting.

[0041] Embodiment 4

[0042] As Figure 7 、 Figure 8 shown in the figure, the efficiency-increasing assembly 63 includes a cylinder body 631. The surface of the cylinder body 631 is fixedly connected to the surface of the sliding cylinder 62. A shunt pipe 634 is fixedly connected to the input end of the cylinder body 631. A piston rod 632 is slidably connected to the inner side surface of the sliding cylinder 62. A spring 633 is fixedly connected to the upper surface of the piston rod 632. The bottom end of the piston rod 632 is fixedly connected to the top end of the cutting knife 64. The limiting assembly 66 includes a ball hinge 661.

When the cutting knife 64 moves upward or downward, the elastic strip 664 converts the rigidity into flexible rebound, and the ball hinge 661 rotatably connects the bottom end of the cutting knife 64 with the surface of the cylinder 662, so that the rigid impact between the cutting knife 64 and the cylinder 662 is effectively reduced.

[0044] Example 5

[0045] like Figure 5 , Figure 7 As shown, the indentation assembly 56 includes a motor 561, the surface of the motor 561 is fixedly connected to the inner side surface of the support plate 54, the rotating shaft at the output end of the motor 561 is fixedly connected to the shaft body 562, the surface of the shaft body 562 is fixedly connected to the magnetic ring, the surface of the shaft body 562 near the magnetic ring is connected to the pressure wheel 564 through magnetic force, the surface of the shaft body 562 is fixedly connected to the rubber roller 563, the surface of the rubber roller 563 is slidably connected to the inner side surface of the pressure wheel 564, the enhancement assembly 63 includes a cylinder body 631, the surface of the cylinder body 631 is fixedly connected to the surface of the sliding cylinder 62, the input end of the cylinder body 631 is fixedly connected to the shunt pipe 634, the inner side surface of the sliding cylinder 62 is slidably connected to the piston rod 632, the upper surface of the piston rod 632 is fixedly connected to the spring 633, and the bottom end of the piston rod 632 is fixedly connected to the top end of the cutting knife 64.

[0046] When in use, the bottom of the laminated corrugated cardboard is driven by the gear belt 53. When the motor 561 drives the shaft 562 to rotate, the rubber roller 563 limits the upper position of the corrugated cardboard. The rotation of the motor 561 and the rotation of the gear belt 53 cooperate with each other to transport and press the corrugated cardboard. The pressing wheel 564 is connected to the shaft 562 by magnetic force. The rubber roller 563 can prevent the pressing wheel 564 from deviating when indenting the corrugated cardboard. The elastic strip 664 is arranged between the cylinder 662 and the connecting rod 65. Then the oil pump is depressurized, and the hydraulic oil is squeezed out of the cylinder 631 by the spring 633.
