Description

Technical Field

[0001] The utility model belongs to the technical field of cardboard processing, and in particular relates to a packaging cardboard waste discharge processing device. Background Art

[0002] Cardboard, such as corrugated cardboard, is widely used in industry, such as making cartons for packaging goods. Cardboard is a relatively environmentally friendly material in the industry because of its ability to resist deformation, light weight, low cost, and no pollution.

[0003] During the production and processing of cardboard, a large amount of scraps and waste from punching the cardboard are generated. In the mass production process, if these cardboard wastes are not recycled, it is very cumbersome to deal with them. At present, the more common treatment method is to re-shred these wastes and mix them into pulp. After a series of operations such as impurity removal, they are processed again into items such as packaging paper and paper towels. In the mixing process, the cardboard is mixed with water and various auxiliary materials. During the high-speed stirring process, the cardboard is shredded and refined and then dispersed into pulp.

[0004] However, during the pulping process, the cardboard waste generated by different specifications of cardboard often has different hardness, thickness, etc. During the pulping process, the cardboard is not fully broken up. There are often scraps of paper or pieces of paper adhering to each other and away from the stirring paddle position, attached to the position close to the kettle wall, resulting in a considerable amount of scraps of paper or pieces of paper being unable to be successfully refined during the pulping process.

[0005] Since the action surface of the stirring paddle is limited, the only way is to manually use tools such as claws to move the scraps or pieces of paper near the kettle wall toward the paddle. However, in this process, the scraps or pieces of paper cannot be fully moved to the vicinity of the stirring paddle, and after the slurry is driven to rotate by stirring, a large amount of scraps or pieces of paper are still far away from the stirring area. In actual operation, this method is prone to collision with the stirring paddle by tools such as claws, causing safety hazards.

[0006] Therefore, in the actual production process, facing the pulping process, how to fully and evenly mix a large amount of cardboard waste into a homogenous pulp has become a technical problem that needs to be solved urgently. Utility Model Content

[0040] Example 1

[0041] like Figure 1-5 As shown, a packaging cardboard waste discharge and treatment device includes a pulp mixing kettle 1, and a lifting and distributing mechanism 2 is assembled and connected at the top of the pulp mixing kettle 1. Specifically, a ring-shaped mounting plate located at the mouth is welded on the top of the pulp mixing kettle 1, and the lifting and distributing mechanism 2 is installed on the ring-shaped mounting plate. According to the existing method, a pulp discharge port 11 is installed at the lower end of the side wall of the pulp mixing kettle 1 to discharge pulp.

[0042] The lifting and adjusting mechanism 2 comprises cylinder lifting components symmetrically arranged on both sides; at the same time, a transverse connecting bridge plate 25 is assembled and connected between the cylinder lifting components. During the lifting process of the cylinder lifting components, the transverse connecting bridge plate 25 is lifted and lowered.

[0043] The lifting assembly of the above-mentioned horizontal connecting bridge plate 25 is connected with a slidably adjustable stirring component. By slidingly adjusting the stirring component, during the working process, the stirring component is adjusted until the stirring component can fully stir and crush the shredded paper and shredded paper blocks that cannot be stirred and crushed near the side wall of the pulping kettle 1, thereby improving the pulping effect.

[0044] Specifically, the stirring assembly includes an adjustment seat 24 slidably connected to the transverse connecting bridge plate 25. The specific sliding adjustment method is: a rectangular adjustment opening is opened on the transverse connecting bridge plate 25, and two long adjustment screws 26 arranged at intervals are fixedly connected in the rectangular adjustment opening; the adjustment seat 24 is slidably connected between the long adjustment screws 26, and a pair of nuts 261 located on both sides of the adjustment seat 24 are respectively threadedly connected to the long adjustment screws 26.

[0045] During operation, loosen the nut and slide the adjustment seat 24. The bottom of the adjustment seat 24 is fixedly assembled and connected with a stirring motor. According to the existing conventional method, the stirring motor is assembled and connected with a material shaft (the material shaft is installed on the output shaft of the stirring motor through a coupling), and the lower end of the material shaft is assembled and connected with a special-shaped stirring paddle component 3, and the special-shaped stirring paddle component 3 includes a mounting ring body 31 installed on the material shaft (the specific installation method adopts a detachable installation: the mounting ring body 31 is assembled and connected with a long pin screw 32, and the long pin screw 32 is threadedly connected to the mounting ring body 31 and the material shaft; the long pin screw 32 is threadedly connected with a nut positioned outside the mounting ring body 31).

[0046] A number of special-shaped paddle plates 33 (made of stainless steel, the special-shaped paddle plates 33 are tilted, specifically designed to be tilted 30 degrees, to reduce resistance and to ensure that the debris is fully impacted and refined) are assembled and connected to the mounting ring body 31. The special-shaped paddle plates 33 include an integrally formed outer U-shaped portion 331 and an inner L-shaped portion; the inner L-shaped portion and the outer U-shaped portion 331 are respectively located at the inner and outer sides of the mounting ring body 31.

[0047] During the operation, the operator loosens the nut 261 in the above manner and then adjusts the adjustment seat 24-stirring motor structure to a position close to the wall of the slurry mixing kettle 1 on one side (in the actual operation, in order to ensure that the special-shaped stirring paddle component 3 does not hit the kettle wall, a safety marking line is engraved on the horizontal connecting bridge plate 25, and the adjustment seat 24 stops adjusting after it is adjusted to the safety marking line).

[0048] This working method can increase the stirring and slurry mixing area during the working process, ensuring that the special-shaped stirring paddle component 3 can fully stir and refine the cardboard scraps attached to the kettle wall (using the impact effect of the slurry, which is increased when close to the kettle wall) and accumulated near the kettle wall.

[0049] The special-shaped pulp plate 33 comprises an outer U-shaped portion 331 and an outer U-shaped portion 332; the outer U-shaped portion 332 and the outer U-shaped portion 331 are respectively located at the inner and outer sides of the mounting ring body 31, with the purpose that: during the working process, when stirring and shredding paper scraps, the special-shaped pulp plate 33 with the special-shaped structure can increase the stirring and shredding effect of paper scraps, and secondly, the mounting ring body 31 can be used as a dividing line to fully refine the paper scraps on the inner and outer sides.

[0050] Specifically, a welding end is integrally formed at the inner end of the outer U-shaped portion 331 , and the welding end is welded to the outer side wall of the mounting ring body 31 .

[0051] At the same time, in order to strengthen the connection stability between the special-shaped stirring paddle component 3 and the material shaft, a plurality of oblique support rods 34 are welded at the bottom of the mounting ring body 31, and the oblique support rods 34 are welded to the lower end of the material shaft.

[0052] Example 2

[0053] like Figure 1-5 As shown, in this embodiment, based on the structure of the embodiment 1, a plurality of tooth-shaped openings 333 are provided on the outer U-shaped portion 331 and the outer U-shaped portion 332. The tooth-shaped openings 333 are designed to improve the effect of shredding cardboard scraps. During operation, the cardboard scraps hit the tooth-shaped openings 333 and are further shredded by the tooth-shaped openings 333.

[0054] The front and rear side walls of the adjustment seat 24 are respectively equipped with a plurality of rollers 241 that roll on the horizontal connecting bridge plate 25. Specifically, the rollers are rotatably connected with wheel arms, which are installed on the adjustment seat 24. During the adjustment process, the flexibility of the adjustment is increased by rolling the rollers 241.

[0055] Example 3

[0057] Both ends of the above-mentioned horizontal connecting bridge plate 25 are respectively assembled and connected to the slide pipe 22. During the working process, the cylinders 21 on both sides work at the same time. At this time, the horizontal connecting bridge plate 25 carries the above-mentioned adjustment seat 24-motor structure to descend (the purpose is: when the amount of slurry is small, the slurry in the kettle can be fully stirred by descending). During the descent, the spring 23 is compressed. When resetting, as the cylinder 21 is closed, it is reset under the restoring force of the spring 23.

[0058] According to the existing method, the cylinder barrel of the cylinder 21 is installed with a connecting plate, and according to the existing method of fixing the cylinder 21, the connecting plate is installed on the external fixing frame.
