Description

Technical Field

[0001] The invention belongs to the technical field of corrugated paper production, and specifically discloses a production system for low-weight reinforced corrugated paper. Background Art

[0002] Corrugated paper is made by processing base paper into a wavy structure through corrugated rollers, and then pasting base paper on both sides to form corrugated cardboard. Corrugated cardboard is currently the most commonly used packaging paper. Corrugated cardboard is made into packaging cartons, which can be suitable for the packaging of most items. Since corrugated paper has a certain cushioning effect and can better protect items, packaging boxes made of corrugated cardboard are widely favored by people.

[0003] In order to increase the value of packaging cartons, people have been conducting research and improvements on packaging cartons, corrugated cardboard, etc., in order to reduce costs, reduce weight, increase strength, facilitate production, improve the efficiency of automated production, and facilitate production on a multi-layer corrugated cardboard forming machine production line with a high degree of automation.

[0004] At present, in order to reduce the gravity of packaging cartons, corrugated board is made of base paper with lower grammage. Since this type of low-grammage base paper uses more plant fibers and is mixed with some waste pulp during the production process, in order to keep its weight low, the expansion property is relatively large. This type of base paper needs to increase the humidity before being processed into corrugated paper with a corrugated structure using corrugating rollers, and needs to be dried after forming. At present, paper drying is carried out by hot air blowing, which will cause uneven shrinkage of corrugated paper, poor forming, and quality damage. At the same time, the hot air blowing method of drying consumes a lot of energy, has low heat utilization efficiency, and is easy to cause environmental pollution. Summary of the invention

[0005] The purpose of the present invention is to provide a production system for low-weight reinforced corrugated paper to solve the problem that in the process of preparing corrugated paper using low-weight base paper, the drying process of the corrugated paper easily causes uneven shrinkage and poor forming.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the present invention is: a production system for low-weight reinforced corrugated paper, which includes a pulping machine, a slag discharger, a pulping machine, papermaking equipment, a corrugator and a drying mechanism in sequence, wherein the drying mechanism includes a box body, an inlet and an outlet are provided in the middle of the box body, and a plurality of support plates are provided in the box body between the inlet and the outlet, and the plurality of support plates are evenly spaced, and the upper ends of the support plates are teeth that can cooperate with the corrugated paper; a drying mechanism for drying the corrugated paper is provided between adjacent support plates, and a reciprocating mechanism is provided on both sides of the box body, and the reciprocating mechanism is used to push the corrugated paper back and forth in a direction perpendicular to the support plate.

[0007] The working principle of this basic solution is that when manufacturing corrugated paper, this system can use waste pulp and plant fiber to mix and prepare low-weight base paper, and then pass it through the corrugator to prepare corrugated paper. The waste pulp and wood fiber are passed through the pulping machine, the slag discharger, the pulping machine, the papermaking equipment, the corrugator and the drying mechanism in sequence. After the base paper is processed by the corrugator, the drying mechanism is needed to dry and shape the corrugated paper.

[0008] When the corrugated paper is dried by the drying mechanism in this system, the formed corrugated paper is placed in the box from the entrance, and the corrugated paper is supported by a support plate. The teeth on the support plate can cooperate with the corrugated paper to prevent the corrugated paper from deforming during the drying process. After the corrugated paper enters the box, the drying mechanism can be started to dry the corrugated paper, and the reciprocating mechanism can be started to push the corrugated paper to move back and forth. Since the drying mechanism is located between the support plates, the corrugated paper can be dried evenly. The reciprocating movement of the corrugated paper during the drying process can make the corrugated paper not only dried evenly but also completely, thereby ensuring that the corrugated paper shrinks evenly after drying and has better forming.

[0009] The beneficial effects of this basic scheme are:

[0010] 1. The drying mechanism in this system uses multiple support plates with teeth to support the formed corrugated paper, which can ensure the shape of the corrugated paper during the drying process and prevent it from deforming during the drying process.

[0011] 2. The drying mechanism in this system is set between the support plates to dry the corrugated paper. At the same time, a reciprocating mechanism is set to push the corrugated paper to move back and forth, so that the corrugated paper on the support plate can be dried evenly and comprehensively. This ensures that the drying process of the corrugated paper is uniform, avoiding the shrinkage of the corrugated paper due to drying and affecting its overall structure.

[0012] Compared with the prior art, this system processes corrugated paper, dries the corrugated paper evenly and comprehensively through a drying mechanism, so that the corrugated paper shrinks evenly, and supports the corrugated paper by the teeth of the support plate to shape the corrugated paper so that the corrugated paper is better formed.

[0013] Furthermore, the drying mechanism comprises a branch pipe, the branch pipe is provided with a through hole, the inner wall of the box body is provided with a driving mechanism for driving the branch pipes to rotate respectively, and the other end of the box body is provided with an air pump connected to the branch pipe.

[0014] Drying gas is introduced into the straight pipe through an air pump, and the branch pipe is driven to rotate through a driving mechanism. The drying gas will flow into between the two support plates through the straight pipe and the through hole to dry the corrugated paper supported above the support plates.

[0015] Furthermore, the driving mechanism includes a motor and a rotating rod, the motor drives the rotating rod to rotate, the rotating rod is provided with a main gear, and the branch pipe is provided with a slave gear meshing with the main gear.

[0016] The motor drives the rotating rod to rotate, the rotating rod drives the main gear to rotate, the main gear drives the slave gear to rotate, thereby driving all branch pipes to rotate, and then the motor drives all branch pipes to rotate, so as to achieve comprehensive and uniform drying of corrugated paper.

[0017] Furthermore, the reciprocating mechanism includes a rotating shaft and a cam. A rotating shaft is provided on both sides of the box body. The cam is fixed on the rotating shaft. The cams on both sides of the box body cooperate with each other to push the corrugated paper on the support plate to move back and forth. A conveyor belt is connected between the rotating shaft and the branch pipe.

[0018] Through the cooperation of the cams on both sides of the box, the corrugated paper on the support plate can be pushed back and forth in a direction perpendicular to the support plate, so that the corrugated paper is more comprehensive during the drying process. The rotation power of the cam comes from the driving mechanism, which reduces the overall power source of the drying mechanism.

[0019] Furthermore, a stop plate is provided on the box body above the support plate, and the upper end of the support plate is wrapped with a rubber sleeve.

[0020] The butt plate can further fix the corrugated paperboard in a shaped manner, and the rubber sleeve can prevent the support plate from damaging the corrugated paper.

[0021] Furthermore, the box body is provided with conveying rollers on both sides of the outlet and the inlet.

[0022] The conveying roller facilitates the transmission of the dried corrugated paper, making the overall use of the drying mechanism more automated. BRIEF DESCRIPTION OF THE DRAWINGS

Conveying rollers 13 are provided on both sides of the outlet 12 and the inlet 11 of the box body 10, respectively. The conveying rollers 13 are used to convey the corrugated paper into and out of the box body 10. A plurality of support plates 20 are provided between the inlet 11 and the outlet 12 in the box body 10. The plurality of support plates 20 are evenly spaced, and the upper end of the support plate 20 is a tooth 21 that can cooperate with the corrugated paper. In order to better protect the corrugated paper, the upper end of the support plate 20 is wrapped with a rubber sleeve, and the support plate 20 is arranged along the line connecting the outlet 12 and the inlet 11. A stop plate 22 is provided on the box body 10 above the support plate 20, and the stop plate 22 is used to cooperate with the support plate 20 to limit the shape of the corrugated paper.

[0030] A drying mechanism for drying corrugated paper is arranged between adjacent support plates 20. The drying mechanism includes a branch pipe 30. Both ends of the branch pipe 30 are rotatably connected to the box body 10. A circular hole is provided at the right side of the box body 10 where it is connected to the branch pipe 30. An air pump 32 is arranged outside the box body 10. The air pump 32 is connected to the branch pipe 30 through the circular hole. Through holes 31 are arranged on the branch pipe 30. The air pump 32 is arranged around the branch pipe 30 to pass the gas pumped by the air pump 32 into the space between the two support plates 20 to dry the corrugated paper. A driving mechanism for driving the branch pipe 30 to rotate is arranged on the inner wall of the box body 10. The driving mechanism includes a motor 33 embedded in the inner wall of the box body 10 and a rotating rod 34 connected to the output shaft of the motor 33. The rotating rod 34 is provided with a main gear 35. A slave gear 36 is arranged on the branch pipe 30. The main gear 35 is meshed with one of the slave gears 36. Adjacent slave gears 36 are meshed with each other, thereby driving all the branch pipes 30 to rotate.

[0031] A reciprocating mechanism is provided on both sides of the box body 10, and the reciprocating mechanism is used to reciprocate the corrugated paper in a direction perpendicular to the support plate 20. The reciprocating mechanism includes a rotating shaft 40 and a cam 41. The rotating shaft 40 is provided on both sides of the box body 10 in a direction perpendicular to the support plate 20, and the cam 41 is fixed on the rotating shaft 40. The cams 41 on both sides of the box body 10 cooperate with each other to push the corrugated paper on the support plate 20 to move back and forth. A conveyor belt 42 is connected between the rotating shaft 40 and the branch pipe 30, and the rotation of the rotating shaft 40 is driven by the branch pipe 30 through the transmission belt.

[0032] The specific implementation process is as follows: When manufacturing corrugated paper, this system can use waste pulp and plant fiber to mix and prepare low-weight base paper, and then pass it through the corrugator to prepare corrugated paper. The waste pulp and wood fiber are passed through the pulping machine, the slag discharger, the pulping machine, the papermaking equipment, the corrugator and the drying mechanism in sequence. After the base paper is processed by the corrugator, the drying mechanism is required to dry and shape the corrugated paper.

[0033] When the corrugated paper is dried by the drying mechanism in the present system, the formed corrugated paper is placed into the box body 10 from the inlet 11, and the corrugated paper is supported by the support plate 20. The teeth 21 on the support plate 20 can cooperate with the corrugated paper to prevent the corrugated paper from deforming during the drying process, and then the corrugated paper is pressed against the plate 22. In the present solution, the plate 22 can be slidably arranged on the upper part of the box body 10, and is electrically controlled to slide up and down to press against the corrugated paper.

[0034] After the corrugated paper enters the box 10, drying gas is introduced into the straight pipe through the air pump 32, and the branch pipe 30 is driven to rotate by the driving mechanism. The drying gas will flow into the space between the two support plates 20 through the straight pipe and the through hole 31, and the corrugated paper supported above the support plate 20 is dried. At the same time, the reciprocating mechanism is started to push the corrugated paper to move back and forth. Through the cooperation of the cams 41 on both sides of the box 10, the corrugated paper on the support plate 20 can be pushed back and forth in a direction perpendicular to the support plate 20. Since the drying mechanism is located between the support plates 20, the corrugated paper can be dried evenly. The reciprocating movement of the corrugated paper during the drying process can make the corrugated paper not only dried evenly but also completely, thereby ensuring that the corrugated paper shrinks evenly after drying and has better forming.
