Description

Technical Field

[0001] The present invention relates to the field of paperboard hydrolysis equipment, and more particularly to waste paper processing equipment for producing boxboard. Background Art

[0002] In the common activity of collecting fibers from cardboard, the cardboard is first broken into many smaller cardboards, and these small cardboards are thrown into a hydrolysis tank for stirring so that the fibers can be decomposed from the cardboard.

[0003] However, the small volume of the cardboard will make it difficult for the cardboard to rub against each other when following the water flow. The difficulty in rubbing against each other means that the hydrolysis efficiency of the cardboard is not high. Large cardboard can have a higher probability of mutual friction when stirring the water flow, but because of its large area, the efficiency of following the water flow is low, and therefore the hydrolysis efficiency is not high. Summary of the invention

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1

[0021] See also Figure 1-2 and Figure 5 A waste paper processing device for boxboard production includes a vertical plate 1, a stirring grinding wheel 3 and a driving element. The driving element is arranged on one side of the vertical plate 1. A slitting mechanism, a flattening mechanism and a stirring mechanism are arranged on one side of the vertical plate 1. The design puts the carton on the conveyor belt, and feeds the carton to the bottom of the flattening mechanism through the conveyor belt or other conveying mechanism. The flattening mechanism presses the fluffy carton into a flat carton, and then feeds the carton into the slitting mechanism. The slitting mechanism cuts the carton, thereby cutting a large carton into multiple smaller carton boards, and at the same time, multiple cuts are made on these small carton boards, which can not only ensure that the volume of the small carton board is not too small, but also expand the area of ​​the cut, so that the fiber can be more easily hydrolyzed from the cut, thereby improving the efficiency of hydrolyzing the carton board.

[0022] The slitting mechanism includes a turntable 5, a slider 6, a center wheel 7, a through opening 9 and a slide 10. The turntable 5 is provided with a slide 10, and the slider 6 is slidably connected in the slide 10. The turntable 5 is provided with a through opening 9. The output end of the driving element is eccentrically fixedly connected to the center wheel 7 through the through opening 9. The outer side of the center wheel 7 is rotatably connected to the slider 6. A through slot 8 for cardboard to pass through is provided on one side of the slide 10. A lower slitting knife 17 is fixedly connected to one side of the slider 6. The cardboard passing through the through slot 8 is located on the moving path of the lower slitting knife 17. The turntable 5 swings in the vertical plate 1, and the vertical plate 1 is fixedly connected to the ground.

[0023] Both sides of the through slot 8 are elastically connected with side cutting knives 16. Cardboard can be conveyed manually or by conveyor belt through the through slot 8. Because this feeding method is very common and not the focus of improvement of this design, this design will not be described in detail here. Then, the driving element is turned on. The driving element can be a device with torque output capability such as a motor or a hydraulic motor. When the driving element drives the center wheel 7 to rotate eccentrically, the center wheel 7 will drive the slider 6 to slide up and down in the slide slot 10, thereby driving the turntable 5 to swing in the vertical plate 1. Specifically, Figure 5The small cardboard shown has two cutting steps at the same time. In the first step, the swinging turntable 5 will squeeze the cardboard through the two side walls of the through groove 8. The side walls of the through groove 8 can give the cardboard a cutting force from the side through the side cutting knife 16. This force will cut the side of the cardboard, but this cutting is not enough to cut the entire cardboard; the second step is that the downward sliding block 6 will drive the lower cutting knife 17 to cut the through groove 8 from top to bottom. This cutting can cut the entire through groove 8. Therefore, within the time when the sliding block 6 moves down once, both sides of the cardboard will be cut once by the corresponding side cutting knife 16. This can not only ensure that the volume of the small cardboard is not too small, but also increase the area of ​​hydrolyzed fibers by expanding the area of ​​the soft incision. It can be known that the fibers at the incision are most susceptible to wear and tear, and are always hydrolyzed first.

[0024] Embodiment 2

[0025] See also Figure 1 , Figure 3 and Figure 4 On the basis of the above embodiment, the flattening mechanism includes a connecting plate 12 and a pressing plate 13. The connecting plate 12 is fixedly connected to the output end of the driving element. The pressing plate 13 is fixedly connected to one side of the connecting plate 12. The cardboard passing through the through slot 8 is located on the rotation path of the pressing plate 13. The connecting plate 12 is driven to rotate by the driving element, and the connecting plate 12 drives the pressing plate 13 to flatten the carton, so that the carton can be turned into a cardboard, which can move unhindered in the through slot 8. At the same time, the cardboard is more convenient to cut than the carton.

[0026] The stirring mechanism includes a refinement component and a material discharge component. The refinement component includes a cover plate 2 and a stirring grinding wheel 3. A plurality of filter ports are provided on the side wall of the stirring grinding wheel 3. A conical hole is provided inside the stirring grinding wheel 3. The turntable 5 is rotated and placed in the conical hole. The outer side of the stirring grinding wheel 3 is detachably connected to the cover plate 2. A hydrolysis tank 4 is provided below the stirring grinding wheel 3. An extension rod on the stirring grinding wheel 3 extends into the hydrolysis tank 4. A faucet for spraying water into the stirring grinding wheel 3 is provided on one side of the stirring grinding wheel 3. After the faucet is turned on, water is sprayed into the stirring grinding wheel 3, and the water enters the stirring grinding wheel 3 through the filter port. At this time, the cut small cardboard will fall from the slide 10, and the turntable 5 will press the small cardboard between the turntable 5 and the stirring grinding wheel 3 during the swinging process. Due to the friction resistance brought by the small cardboard, the stirring grinding wheel 3 and the turntable 5 will swing at a differential speed, and the gap between the turntable 5 and the stirring grinding wheel 3 will repeatedly rub the small cardboard, and the water flow entering the stirring grinding wheel 3 will soak the cardboard, so that the limit on the cardboard can be more easily decomposed by friction.

[0027] The material discharge assembly includes a material discharge trough 14, a first wedge-shaped top block 11 and a second wedge-shaped top block 15. The first wedge-shaped top block 11 is fixedly connected to the center wheel 7, and the second wedge-shaped top block 15 is fixedly connected to the cover plate 2. The second wedge-shaped top block 15 is located on the rotation path of the first wedge-shaped top block 11. The cover plate 2 and the stirring grinding wheel 3 are elastically and detachably connected, and the cover plate 2 is provided with a material discharge trough 14. The friction is continued until the thickness of the small cardboard is smaller than the gap between the stirring grinding wheel 3 and the turntable 5, the second wedge-shaped top block 15 swings with the stirring grinding wheel 3, and the first wedge-shaped top block 11 rotates with the center wheel 7. Therefore, when the first wedge-shaped top block 11 and the second wedge-shaped top block 15 collide, the cover plate 2 is lifted from the stirring grinding wheel 3 by elastic force, and the small cardboard that enters the bottom of the chute 10 and the impact of the water flow will push the previously rubbed small cardboard from the feed chute 14 down into the hydrolysis tank 4. When the first wedge-shaped top block 11 and the second wedge-shaped top block 15 are staggered, the cover plate 2 will be in a relatively closed state with the stirring grinding wheel 3 under the action of elastic force until the next time the vertical plate 1 and the second wedge-shaped top block 15 collide. The small cardboard falling into the hydrolysis tank 4 will be continuously stirred by the stirring grinding wheel 3, thereby accelerating the efficiency of fiber hydrolysis.
