Description

Technical Field

[0001] The present application relates to the technical field of corrugated paper manufacturing, and in particular to a corrugated paper processing raw material mixing device. Background Art

[0002] Corrugated paper is a plate-like material made of noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into single corrugated paperboard and double corrugated paperboard. Corrugated paper has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, convenient storage and transportation, etc. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used. The raw materials for the production of corrugated paper are mostly pulp blocks, which are prepared into pulp raw materials through pulping to prepare for the subsequent preparation of corrugated paper. Therefore, the pulp mixing device used for corrugated paper production is one of the important devices used to manufacture corrugated paper.

[0003] Most existing pulp mixing devices use a mixer with a cutting mechanism inside. First, a large amount of hot water is filled in the mixer, and then the pulp block is put into it. After the pulp block absorbs the hot water, it is continuously cut and crushed by the cutting knife in the mixer to convert the solid pulp block into a viscous pulp. After the pulp is flattened, squeezed, and dried, it becomes the raw material for making corrugated board. However, after the pulp block is put into the existing mixer, the pulp block has a long process of absorbing water. The part that does not absorb water flows continuously with the water flow in the water and is not easy to be cut by the mixer. This will slow down the processing process and it needs to be given a sufficiently long mixing time. Therefore, in order to solve the above problems, the present application provides a corrugated paper processing raw material mixing device.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that the existing mixer has poor pulverizing effect on pulp blocks and requires a long processing time, the present application provides a corrugated paper processing raw material mixing device.

[0006] The present application provides a corrugated paper processing raw material mixing device, comprising a stirring tank and a pulp block to be dissolved, wherein a stirring shaft is rotatably connected inside the stirring tank, a feeding structure is arranged at the top of the stirring tank, and the feeding structure pushes the pulp block into the stirring tank at a uniform speed, and a spraying structure for pre-wetting the pulp block is arranged at the top of the stirring tank;

[0007] The top of the stirring shaft is movably connected with a telescopic mechanism, which includes an upper cutter. The upper cutter changes with the rotation speed of the stirring shaft and the distance from the inner wall of the stirring tank. The upper cutter moves 5-10 cm toward the inner wall of the stirring tank to cut the pulp block.

[0008] The spray structure is used for pre-wetting, and the upper cutter in the telescopic mechanism uses the change in the rotation speed of the stirring shaft to adjust the distance from the inner wall of the stirring tank, so that the pulp block can be cut at a high rotation speed, thereby reducing the subsequent stirring and cutting time.

[0009] Preferably, as the rotation speed of the stirring shaft increases, the distance between the upper cutter and the inner wall of the stirring tank decreases.

[0010] Preferably, the telescopic mechanism further comprises a sleeve and a slide rod of a coaxial sleeve, the end of the sleeve is welded to the stirring shaft, the front end of the slide rod is welded to the upper cutter, and the end of the slide rod is elastically connected to the stirring shaft via a spring.

[0011] Preferably, the front end portion of the slide rod is also movably connected to a roller, and the radius of the roller tangent is greater than the maximum radius of the upper cutter.

[0012] Preferably, the feeding structure comprises a conveyor belt and a transfer groove welded to the outer wall of the stirring tank, a channel is provided at the connection position between the stirring tank and the transfer groove, and the conveyor belt and the transfer groove are both arranged to be inclined toward the stirring shaft.

[0013] Preferably, hydraulic cylinders are fixedly connected to the inner walls on both sides of the adapter groove by bolts, and pressure plates are fixedly connected to the output ends of the hydraulic cylinders, and the pressure plates cooperate with each other to clamp the outer sides of the pulp block.

[0015] Preferably, the bottom end of the stirring shaft is also provided with a plurality of lower cutting knives in a circular array.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] By arranging a telescopic mechanism on the upper section of the stirring shaft of the stirring tank, the upper cutter of the telescopic mechanism can be expanded outward by changing the rotation speed of the stirring shaft. The stirring tank is also provided with a feeding structure that cooperates with the expansion of the upper cutter to feed the inside of the stirring tank intermittently at a uniform speed, and cooperate with the cutting of the upper cutter, thereby shortening the stirring time of the pulping block in the stirring tank, accelerating the pulping, and at the same time reducing the resistance of the cutter and improving the durability of the device.

[0018] By arranging a spraying structure above the outlet position of the feeding structure, the pulp block is pre-wetted, thereby further improving the rate of cutting and stirring the pulp block. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1 - Figure 5 This application is described in further detail.

[0026] Embodiment 1:

[0027] Reference Figure 1 - Figure 5 A corrugated paper processing raw material mixing device includes a stirring tank 1 and a pulp block 8 to be dissolved. The stirring tank 1 is rotatably connected to a stirring shaft 5. The bottom end of the stirring shaft 5 is also provided with a plurality of lower cutting knives 10 in a circular array. The lower cutting knives 10 are used to stir and cut the pulp block 8 that falls into the stirring tank 1 to complete the pulping operation.

[0028] A feeding structure is provided at the top of the stirring tank 1, and the feeding structure includes a conveyor belt 2 and a transfer groove 3 welded to the outer wall of the stirring tank 1. A channel is opened at the connection position between the stirring tank 1 and the transfer groove 3, and the conveyor belt 2 and the transfer groove 3 are both inclined toward the stirring shaft 5. The ends of the conveyor belt 2 and the transfer groove 3 are close to each other. The conveyor belt 2 is used to transport the pulp blocks 8. The pulp blocks 8 fit together, thereby applying a forward thrust to the front end one, so that it protrudes from the inner wall of the stirring tank 1.

[0029] The hydraulic cylinder 4 is bolted to the inner walls of both sides of the adapter groove 3, and the output end of the hydraulic cylinder 4 is fixedly connected to a pressure plate 41, and the pressure plates 41 cooperate with each other to clamp the outer side of the pulp block 8. When the conveyor belt 2 pushes the subsequent pulp block 8 to move forward, the frontmost pulp block 8 will be pushed into the mixing tank 1. In order to prevent the pulp block 8 from falling off as a whole, the conveyor belt 2 is set to intermittent transmission. During the transmission of the conveyor belt 2, the two pressure plates 41 do not squeeze the pulp block 8 to ensure that the pulp block 8 can be pushed forward for a distance. After the pushing is completed, the pressure plates 41 quickly clamp, and the pulp block 8 protrudes a distance at this time. At the same time, the stirring shaft 5 rotates. Under the action of centrifugal force, the upper cutter 93 moves to one side of the inner wall of the mixing tank 1. At this time, the upper cutter 93 can contact the pulp block 8 and cut the pulp block 8. Since the position of the pulp block 8 is fixed, the cutting accuracy will be better, and the small pulp blocks 8 that fall can be crushed faster.

[0030] The feeding structure pushes the pulp block 8 to move into the mixing tank 1 at a uniform speed. A spraying structure for pre-wetting the pulp block 8 is arranged at the top of the mixing tank 1. A water pipe 6 is fixedly connected to the top of the mixing tank 1 where the adapter slot 3 is arranged, and a spray pipe 7 is movably connected to the bottom of the water pipe 6. The spray pipe 7 and the water pipe 6 form an angle-adjustable spraying structure. The spray pipe 7 is arranged toward the pulp block 8. The water flow in the spray pipe 7 is used to preliminarily spray the pulp block 8 to make it wet, thereby facilitating the cutting operation of the upper cutter 93 and further reducing the subsequent moisture absorption process.

[0031] The top of the stirring shaft 5 is movably connected with a telescopic mechanism 9, which includes an upper cutter 93. The upper cutter 93 changes with the rotation speed of the stirring shaft 5 and the distance from the inner wall of the stirring tank 1. The upper cutter 93 moves 5-10 cm toward the inner wall of the stirring tank 1 to cut the pulp block 8. The telescopic mechanism 9 also includes a sleeve 91 and a slide rod 92 of a coaxial sliding sleeve. The end of the sleeve 91 is welded to the stirring shaft 5, the front end of the slide rod 92 is welded to the upper cutter 93, and the end of the slide rod 92 is elastically connected to the stirring shaft 5 through a spring 95.

[0032] As the rotation speed of the stirring shaft 5 increases, the distance between the upper cutter 93 and the inner wall of the stirring tank 1 decreases. When the rotation speed of the stirring shaft 5 is large enough, the roller 94 on its side fits against the inner wall of the stirring tank 1 to prevent the upper cutter 93 from directly contacting the inner wall of the stirring tank 1. When the rotation speed of the stirring shaft 5 decreases, the centrifugal force generated is not sufficient to overcome the elastic force of the spring 95. Under the action of the spring 95, the upper cutter 93 is always in the initial position.

[0033] The front end of the slide rod 92 is also movably connected to a roller 94, the radius of the tangent of the roller 94 is larger than the maximum radius of the upper cutter 93, and the roller 94 is arranged to protrude from the end face of the upper cutter 93, so that the roller 94 can contact the inner wall of the mixing tank 1 before the upper cutter 93, thereby preventing the upper cutter 93 from being damaged by the mixing tank 1. The roller 94 can also ensure that there will be no large resistance when contacting the inner wall of the mixing tank 1.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
