Technical Field

[0001] The present invention relates to the technical field of waste paper recycling, and particularly to a production process for high-strength corrugated paper made from waste paper. Background Art

[0002] With the improvement of people's awareness of resource conservation, people gradually use waste paper for recycling production to reduce resource waste. During the process of waste paper recycling production, it is necessary to use it as raw material for production again. However, there are still certain defects in the existing production process. In the existing process, water is directly added to the shredded waste paper for stirring, and there will be larger waste paper that has not been completely shredded, resulting in difficulty in quickly dispersing it into pulp, reducing the processing efficiency of the device for waste paper;

[0003] The patent with the patent authorization announcement number CN222083193U discloses a waste paper recycling device for the production of recycled corrugated paper. Through the coordinated use of a sieve mesh, a second motor, a rotating rod, and a cam, under the rapid beating of the cam on the sieve mesh, the waste paper that has not been completely shredded is screened out, improving the screening efficiency of the shredded paper; through the coordinated use of a hollow block, a first motor, a winding roller, a traction rope, a supporting block, a discharge port, and a guide plate, the larger waste paper screened out is sent back into the rectangular pipe for processing again until it is completely shredded, enabling the waste paper to be fully shredded before adding water for stirring, so that it can be quickly dispersed into pulp, improving the processing efficiency of the device for waste paper;

[0004] The patent with the patent authorization announcement number CN117468260A discloses a production process for waste paper recycled corrugated paper with recycled pulp. The pulp splashed out during the forming process of the forming fabric and leaked from the forming fabric of the forming equipment is recycled through a pulp recovery tank. After filtering the recycled pulp, a modifying preparation is added and stirred evenly to obtain a modified fine fiber pulp, and the fine fiber pulp is directly used to assist in the forming of the forming fabric. Not only is the recycled pulp recycled, but also the structural strength and toughness of the formed paper can be improved;

[0005] In the above-mentioned disclosed patents, the problems raised above are solved, but there are still the following problems in the devices or processes in these patents. During the process of crushing the waste paper raw material in the above-mentioned devices or processes, single structures are used for crushing. If it is directly crushed into smaller-sized debris, the crushing time will be prolonged. If the crushing size is larger, the situation of slower dissolution is likely to occur, affecting the production efficiency of waste paper recycling. And in the filtering process in the above-mentioned devices or processes, filtering is carried out only through a filter screen. The liquid at the upper end of the filter screen is in a static state, and impurities in the liquid are prone to deposition, which is likely to affect the effect of the filter screen, and thus is likely to affect the production efficiency of the device or process.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0034] Embodiment 1: This embodiment is as Figures 1 - 4As shown in the figure, in order to solve the problem that it is difficult for existing devices to perform rapid soaking, the process of rapid pulverization and soaking of waste paper by the devices related to this process is disclosed, achieving the effect of rapid production of the devices related to this process. The specific content is as follows:

[0035] The main support board 1 and the production frame 2 fixedly installed on the upper end of the main support board 1; a sealing cover 3 is rotatably installed on the upper end of the production frame 2, and a pulping area 4 and a papermaking area 5 are provided inside the production frame 2. Moreover, a coarse grinding roller 6 and a fine grinding roller 8 are arranged inside the production frame 2, a driving structure 7 is arranged outside the production frame 2, and a concentration pulping machine 9 is fixedly installed inside the production frame 2. An outlet cylinder 28 is fixedly installed on the upper end of the concentration pulping machine 9, and a multi-stage filter 12 is fixedly installed on the upper end of the outlet cylinder 28. Moreover, a suction pump structure I 10 and a suction pump structure II 11 are arranged inside the production frame 2.

[0036] When using the devices related to the production process of recycling waste paper into high-strength corrugated paper, first place the device at the position where work needs to be carried out. First, open the sealing cover 3 and place the waste paper on the upper end of the guide plate 13 so that the waste paper scatters between the coarse grinding roller 6 and the fine grinding roller 8. At this time, the driving structure 7 will drive the coarse grinding roller 6 and the fine grinding roller 8 to rotate and grind the waste paper. At the same time, the setting of the guide plate 13 can enable the coarse grinding roller 6 and the fine grinding roller 8 to fully grind the waste paper. After grinding, the waste paper will enter the inside of the pulping area 4. At this time, water is added into the inside of the pulping area 4 through a water pipe, and the driving motor 14 drives the main stirring blades 17 and the auxiliary stirring blades 18 to rotate, so that the shredded waste paper after pulverization is fully dissolved with the water flow. The suction pump structure I 10 will transport the dissolved water flow into the inside of the multi-stage filter 12 for filtration, and the filtered water flow will enter the inside of the concentration pulping machine 9 through the outlet cylinder 28. At this time, the concentration pulping machine 9 can further process the waste paper dissolved pulp, and the processed waste paper dissolved pulp will be pumped into the inside of the papermaking area 5 by the suction pump structure II 11. At this time, the liquid inside the papermaking area 5 can be fished out by the fishing mechanism and dried, thus completing the working process of the devices related to this process, effectively improving the working efficiency of this process.

[0037] Example Two: As in this Figures 1 - 6 As shown in the figure, in order to solve the problem that the dissolution speed of existing waste paper pulp is slow, the process of rapid dissolution of waste paper pulp inside the devices related to this process is disclosed, achieving the effect that the devices related to this process can rapidly dissolve waste paper pulp. The specific content is as follows:

[0039] When using the waste paper recycling high-strength corrugated paper production process related device, it is necessary to merge the water flow with the crushed waste paper inside the pulping area 4. At this time, it is necessary to drive the rotating drum 15 to rotate through the driving motor 14, and the rotation of the rotating drum 15 will drive the main stirring blade 17 and the auxiliary stirring blade 18 to rotate through the rotating shaft 16, and the rotating shaft 16 will rotate under the action of the bevel gear set 35 when it revolves, so that the main stirring blade 17 and the auxiliary stirring blade 18 can rotate vertically when they rotate horizontally, so that the water flow inside the pulping area 4 can be turned upside down, thereby accelerating the dissolution of waste paper debris and water flow, shortening the time required for the dissolution process of waste paper debris and water flow, and improving the working efficiency of the process related devices.

[0040] Embodiment 3: This embodiment is as follows Figures 1 - 9 As shown, in order to solve the problem of low filtering effect of the process-related device, a process in which the process-related device can quickly filter is disclosed, and the effect of the process-related device quickly filtering is achieved, and the specific contents are as follows:

[0041] A pulp rapid filtering structure is arranged inside the production frame 2, and the filtering structure includes a protective cover 22 and a rotating rod 23, and the protective cover 22 is mounted on the upper end of the multi-stage filter 12, and the rotating rod 23 is rotatably mounted inside the discharge barrel 28, and the upper end of the rotating rod 23 is connected with the protective cover 22 by a clamping connection, and a mounting block 29 is slidably mounted on the outer side of the rotating rod 23, and a sliding member 30 and a limiting block 31 are slidably mounted inside the mounting block 29, and a filtering blade 34 is fixedly mounted on the end of the sliding member 30 away from the mounting block 29, and a return spring 32 is fixedly mounted on the end of the limiting block 31 close to the sliding member 30, and the rotating rod 23 is fixedly mounted on the outer side of the rotating rod 23. A limit slot 33 is provided inside, and the limit slot 33 is engaged with the limit block 31, a filter plate 24 is engaged and installed inside the multi-stage filter 12, and the filter plate 24 is rotatably connected to the rotating rod 23, and the upper end of the filter plate 24 is tightly fitted with the lower end of the filter blade 34, a connecting rod 26 is rotatably installed inside the discharge cylinder 28, a driven shaft 25 is rotatably installed at the lower end of the production frame 2, and a toothed pulley structure 21 is provided on the outer side of the driven shaft 25 and the rotating cylinder 15, and a bevel gear set 27 is provided on the outer side of the driven shaft 25 and the connecting rod 26, and a bevel gear set 3 36 is provided on the outer side of the connecting rod 26 and the rotating rod 23.

[0042] When using the waste paper recycling high-strength corrugated paper production process related device, it is necessary to filter and separate the waste paper pulp multiple times inside the multi-stage filter 12, and the flow of water can accelerate the filtering effect of the filter plate 24 on the waste paper pulp. In this process, the rotating cylinder 15 will drive the driven shaft 25 to rotate through the toothed belt wheel structure 21 arranged on the outside thereof, and the driven shaft 25 will drive the rotating rod 23 to rotate through the bevel gear set 27, the connecting rod 26 and the bevel gear set 36. The rotation of the rotating rod 23 will drive the filter blade 34 to rotate through the limit block 31. At this time, the filter blade 34 can stir the liquid inside the multi-stage filter 12, so that the liquid inside the multi-stage filter 12 rotates and the filtering effect of the filter plate 24 on the waste paper pulp can be accelerated;

[0043] And after the multi-stage filter 12 has been used for a period of time, it is necessary to clean the impurities on the upper ends of the multiple groups of filter plates 24. During this process, the protective cover 22 needs to be removed from the upper ends of the multiple groups of filter plates 24, and then the mounting block 29 can be slid upward. The sliding of the mounting block 29 will cause the limiting card slot 33 to squeeze the limiting card block 31, and at this time, the limiting card block 31 can squeeze the return spring 32 and cause the return spring 32 to contract. After the limiting card slot 33 is separated from the limiting card block 31, the mounting block 29 can be separated from the rotating rod 23, so that the filter plate 24 can be removed and cleaned, and the filtering effect of the filter plate 24 is ensured, thereby improving the working efficiency of the process-related device and increasing the overall practicality.
