Description

Technical Field

[0001] The present application relates to the field of paperboard production technology, and in particular to a four-layer corrugated paperboard manufacturing device containing reinforcing ribs. Background Art

[0002] Corrugated board manufacturing equipment is industrial equipment used to produce corrugated board, which involves processing base paper into board with a corrugated structure, usually including steps such as fluting, gluing, cutting and shaping to create a strong and cushioning material for packaging purposes.

[0003] like Figure 1 As shown, most of the current corrugated paper adopts a five-layer cardboard design. The five-layer corrugated cardboard includes two layers of corrugated paper surfaces 1, two layers of face paper 2 respectively bonded to the sides of the two layers of corrugated paper away from each other, and lining paper 3 bonded between the two layers of corrugated paper. Since the supporting strength of the corrugated cardboard mainly lies in the corrugated paper in the middle, and the traditional five-layer cardboard processing equipment and processing technology cause the double corrugations to be bonded to the lining paper 3 at staggered peaks, the middle lining paper 3 mainly provides bonding to increase the compressive strength. In order to improve the resource utilization rate of raw materials in the production process of corrugated cardboard, save energy and reduce consumption, a technology of four-layer corrugated cardboard with convex-to-convex bonding of corrugated paper having a higher compressive strength than that of the five-layer corrugated cardboard has emerged.

[0004] Currently, if Figure 2 As shown, in combination with the prior art CN219903599U, the production of four-layer corrugated paperboard mainly includes the steps of base paper preparation, base paper forming a corrugated corrugated structure through a corrugating roller, two corrugated paper surfaces 1 are bonded to form, the third face paper 2 and the fourth face paper 2 are bonded to the two sides of the double corrugated paper in sequence, and the bonded corrugated paperboard is cut into required sizes by a cutting mechanism. However, when the convex-to-convex bonded double-corrugated two-layer paperboard enters the next process, due to the acceleration and deceleration changes of the production equipment and the unbalanced changes of the tension of the base paper and the guiding system, the two layers of double-corrugated paperboard bonded to each other have uneven stretching length changes, uneven flute changes, inconsistent flute pitches, and large flute height changes. In this state, when the double-corrugated paperboard is bonded with the other two face papers to form a four-layer paperboard, unbalanced, unstable, uneven, degummed and cracked, and irregular high and low corrugation phenomena will occur, which affects the various physical indicators that the four-layer paperboard should have, especially causing the supporting strength of the paperboard to be greatly reduced. Summary of the invention

[0005] In order to ensure that the flute shape of two layers of corrugated paperboard remains unchanged after bonding, the pitch between flutes remains consistent, and the flute height remains unchanged, and to improve various physical indicators such as the supporting strength of the paperboard, the present application provides a four-layer corrugated paperboard manufacturing equipment with reinforcing ribs.

[0006] The present application provides a four-layer corrugated paperboard manufacturing device with reinforcing ribs, which adopts the following technical solutions, including:

[0007] frame;

[0008] A spray line pipeline is arranged above the frame, and a plurality of the spray line pipelines are arranged, wherein a linear adhesive is passed through the spray line pipelines;

[0009] A wire feeding mechanism, arranged in the wire spraying pipeline, is used for spraying a wire-shaped adhesive between two layers of corrugated paperboard;

[0010] The movable adjustment mechanism is arranged between the spray line pipeline and the frame, and is used to drive the spray line pipeline to move to adjust the distance between two adjacent spray line pipelines, and adjust the height of the spray line pipeline at the same time.

[0011] By adopting the above technical scheme, when producing corrugated paperboard, the staff first passes the base paper through the corrugated roller to form a corrugated structure after the base paper is prepared, and then before applying glue to the double corrugated corrugated paperboard, the height of the spray line pipeline is adjusted by the mobile adjustment mechanism to adapt to the thickness of the corrugated paperboard, and under the cooperation of the spray line pipeline and the wire feeding mechanism, multiple lines of adhesive are sprayed evenly at intervals along the width direction of the two corrugated corrugated papers that have not been glued together. When one end of the linear adhesive is pneumatically injected into the pressing gap of the pressure roller in the tile mounting machine, the linear adhesive is continuously fed between two sheets of corrugated paper under the drive of the pressure roller, and the two sheets of corrugated paper are driven forward by the tile mounting machine. Multiple longitudinal linear adhesives and the corrugated protrusions that are horizontally coated with glue by the gluing mechanism of the tile mounting machine form a cross "tic-tac-toe shape". Multiple longitudinal linear adhesives act as reinforcing ribs and are pressed into one with the double corrugated corrugated paperboard and dried. Then the double corrugated corrugated paperboard and the surface paper are bonded together by the gluing mechanism. Four layers of corrugated paperboard are formed, and finally the corrugated paperboard is cut into the required size by the cutting mechanism; wherein, by the coordinated use of the spray line pipeline and the wire feeding mechanism, multiple linear adhesives can be sprayed on the corrugated paperboard at uniform intervals along its width direction, and the multiple linear adhesives and the adhesives coated along the corrugated protrusions by the gluing mechanism of the corrugated mounting machine form cross-shaped reinforcing ribs, thereby replacing the middle lining paper of the five-layer corrugated paperboard, not only reducing the dosage of adhesive, but also reducing the use of one layer of lining paper, thereby improving the resource utilization rate of raw materials in the production process of corrugated paperboard, and saving energy and reducing consumption. In addition, the shaped reinforcing ribs make The two layers of double-corrugated cardboards that are glued together enter the next process after gluing, and the length and flute type do not change, and the pitch between flutes can be kept consistent, so that when the two double-corrugated cardboards are glued together with the other two surface papers to form a four-layer cardboard, there will be no unbalanced, unstable, and irregular high and low fluting phenomenon, thereby improving the supporting strength and other physical indicators of the four-layer cardboard; and the movable adjustment mechanism can not only adjust the height of the spray line pipe to adapt to the production of corrugated cardboards of different thicknesses, but also adjust the distance between two adjacent spray line pipes to adapt to the production of corrugated cardboards of different widths, thereby improving the practicability and adaptability of the equipment.

[0012] Optionally, the movement adjustment mechanism includes:

[0013] A support frame is slidably connected to the frame, and a plurality of support frames are provided, and the plurality of support frames correspond one to one to the plurality of spray line pipelines;

[0014] A moving assembly is arranged between the support frame and the frame, and is used to drive the support frame to move;

[0015] The height spacing adjustment component is arranged between the support frame and the spray line pipeline, and is used to connect the support frame and the spray line pipeline and adjust the height spacing between the spray line pipeline and the protrusion of the corrugated paper.

[0016] By adopting the above technical scheme, when the linear adhesive is applied to the corrugated protrusions of the corrugated paper through the movable adjustment mechanism, the staff can first adjust the height distance between the spray line pipe and the corrugated paper protrusion according to the height of the corrugated protrusion in the corrugated paper through the height spacing adjustment component, so that the linear adhesive can be accurately sprayed on the high point protrusion of the corrugated structure, and then adjust the spacing between adjacent spray line pipes through the movable component to make the spacing between adjacent spray line pipes match the preset width scale of the corrugated paperboard. Then the staff starts the wire feeding mechanism to spray the linear adhesive on the corrugated protrusions of the corrugated paper at intervals; wherein the movable component and the height spacing adjustment component can be used in combination to process corrugated paperboards of different widths and thicknesses, without having to replace the equipment for each paperboard size, thereby improving the adaptability and practicality of the equipment and reducing the equipment adjustment cost when producing products of different specifications.

[0017] Optionally, the height spacing adjustment component includes:

[0018] A lifting screw rod is arranged between the support frame and the spray line pipeline, one end of the lifting screw rod is threadedly connected to the support frame, and the other end is rotatably connected to the spray line pipeline;

[0019] The guide rod is arranged between the support frame and the spray line pipeline, one end of the guide rod is slidably connected to the support frame, and the other end is connected to the spray line pipeline.

[0020] By adopting the above technical solution, when adjusting the distance between the spray line pipe and the corrugated paper protrusion through the height spacing adjustment component, the staff first rotates the lifting screw. Since one end of the lifting screw is threadedly connected to the support frame and the other end is rotatably connected to the spray line pipe, the lifting screw will drive the spray line pipe to move up and down. At the same time, under the action of the guide rod, the spray line pipe will not rotate, thereby accurately adjusting the distance between the spray line pipe and the corrugated paper protrusion, so that the linear adhesive can be accurately sprayed on the high point protrusion of the corrugated structure, thereby realizing the processing of corrugated board of different thicknesses, without having to replace equipment for each board size.

[0021] Optionally, the height spacing adjustment component further includes:

[0022] A first pipe hoop is disposed between the lifting screw and the spray line pipeline, the first pipe hoop is detachably sleeved on the outside of the spray line pipeline, and is rotatably connected to the lifting screw;

[0023] The second pipe hoop is arranged between the guide rod and the spray line pipeline. The second pipe hoop is detachably sleeved on the outside of the spray line pipeline and is fixedly connected to the guide rod.

[0024] By adopting the above technical solution, the first pipe clamp and the second pipe clamp are used to achieve a stable connection between the lifting screw, the guide rod and the spray line pipe on the one hand; on the other hand, when the spray line pipe is damaged, blocked or aged, it can be quickly disassembled through the first pipe clamp and the second pipe clamp, which is convenient for subsequent maintenance and replacement.

[0025] Optionally, the mobile component includes:

[0026] A guide rail is fixed to the frame;

[0030] The driving motor is arranged at one end of the gear rotating shaft.

[0031] By adopting the above technical solution, when the support frame is driven to move by the moving component, the driving motor is started first, and then the driving motor drives the gear to rotate, and under the action of the slider and the rack, the gear drives the support frame and the spray line pipeline to move along the guide rail; wherein the slider, the gear, the rack and the guide rail cooperate to ensure, on the one hand, the support frame moves smoothly along the preset direction of the guide rail, and on the other hand, the gear and the rack are always kept in meshing, thereby improving the stability of the operation of the moving component.

[0032] Optionally, the wire feeding mechanism includes:

[0033] The elbow is connected to the inlet end of the spray line pipeline;

[0034] Blowing line air cavity device, connected to the elbow,

[0035] Pneumatic scissors are arranged on one side of the outlet end of the spray line pipe.

[0036] By adopting the above technical scheme, when the linear adhesive is fed into the spray line pipe by the wire feeding mechanism, the wire blowing air cavity device is first started. The wire blowing air cavity device uses the negative pressure principle to suck the linear adhesive into the spray line pipe and feed it between two corrugated papers from one side of the outlet end of the spray line pipe. When the order needs to be changed, the pneumatic scissors can cut the linear adhesive. The input side of the wire-bound adhesive always ensures that the wire is in the spray line pipe. After the wire is used up, there is no need to manually feed the wire into the spray line pipe repeatedly, thereby reducing the labor intensity of the staff.

[0052] The following is combined with Figure 3-Figure 9 This application is described in further detail.

[0053] The present application embodiment discloses a four-layer corrugated paperboard manufacturing device with reinforcing ribs. Figure 3 and Figure 4 The four-layer corrugated paperboard comprises two layers of corrugated paper surface 1, two layers of face paper 2 respectively bonded to the sides of the two layers of corrugated paper away from each other, and multiple linear reinforcing ribs 4 bonded to the vertical protrusions of the two layers of corrugated paper. The linear reinforcing ribs 4 are made of BOPP, PET, DPE, PPT paperboard easy-pull strips, hot-melt composite films and other types of composite films, double-sided paper tapes, self-adhesive tapes, thin adhesive strips containing other sizing papers, and linear tape materials such as cotton threads, industrial yarns, and wood pulp paper threads. The multiple linear adhesives and the adhesives coated along the corrugated protrusions by the gluing mechanism of the tile mounting machine form cross-shaped reinforcing ribs.

[0054] Reference Figure 5 and Figure 6The four-layer corrugated paperboard manufacturing equipment with reinforcing ribs includes a frame 5, and a plurality of spray line pipes 6 are arranged above the frame 5. The plurality of spray line pipes 6 are arranged parallel to each other and spaced apart, and a linear adhesive is passed through the spray line pipes 6. A wire feeding mechanism 7 is arranged on the spray line pipes 6, and the wire feeding mechanism 7 is used to spray the linear adhesive between two layers of corrugated paperboard. A moving adjustment mechanism 8 is arranged between the spray line pipes 6 and the frame 5, and the moving adjustment mechanism 8 is used to drive the spray line pipes 6 to move to adjust the spacing between two adjacent spray line pipes 6, and at the same time adjust the height of the spray line pipes 6.

[0055] When the staff is producing corrugated paperboard, after the base paper is prepared, the height of the spray line pipe 6 is adjusted by the mobile adjustment mechanism 8 to adapt to the thickness of the corrugated paperboard. Then, the base paper is passed through the corrugated roller to form a corrugated structure. Before applying glue to form a double corrugated corrugated paperboard, the spray line pipe 6 and the wire feeding mechanism 7 cooperate to spray multiple lines of adhesive at even intervals along the width direction between the two corrugated corrugated papers that have not yet been glued. When one end of the line adhesive between the two corrugated papers is pneumatically sprayed to the pressure roller of the corrugated paperboard mounting machine, the adhesive is sprayed to the pressure roller of the corrugated paperboard mounting machine. When closing the gap, the linear adhesive is continuously fed between the two corrugated papers under the drive of the pressure roller, and the two corrugated papers are driven forward by the mounting machine. Multiple longitudinal linear adhesives and the corrugated protrusions that are horizontally coated with glue by the gluing mechanism of the mounting machine form a cross "tic-tac-toe shape". The multiple longitudinal linear adhesives act as reinforcing ribs and are pressed into one with the double corrugated paperboard and dried. Then the double corrugated paperboard and the face paper 2 are bonded together by the gluing mechanism to form a four-layer corrugated paperboard. Finally, the corrugated paperboard is cut into the required size by the cutting mechanism.

[0056] In some embodiments, reference Figure 6 and Figure 7 The moving adjustment mechanism 8 includes a plurality of support frames 81 slidably connected to the frame 5, and the plurality of support frames 81 correspond to the plurality of spray line pipes 6 one by one, and a moving assembly 82 is provided between the support frame 81 and the frame 5, and the moving assembly 82 is used to drive the support frame 81 to move. A height spacing adjustment assembly 83 is provided between the support frame 81 and the spray line pipe 6, and the height spacing adjustment assembly 83 is used to connect the support frame 81 and the spray line pipe 6, and adjust the height spacing between the spray line pipe 6 and the corrugated paper protrusion.

[0057] When applying the linear adhesive to the corrugated protrusions of the corrugated paper by moving the adjustment mechanism 8, the staff can first adjust the distance between the spray line pipe 6 and the corrugated paper protrusion according to the height of the corrugated protrusion in the corrugated paper through the height spacing adjustment component 83, so that the linear adhesive can be accurately sprayed on the high point protrusion of the corrugated structure, and then adjust the spacing between adjacent spray line pipes 6 by moving the component 82 to make the spacing between adjacent spray line pipes 6 match the preset width scale of the corrugated board. Then the staff starts the wire feeding mechanism 7 to spray the linear adhesive on the corrugated protrusions of the corrugated paper at intervals.

[0058] In some embodiments, reference Figure 7 and Figure 8 The moving assembly 82 includes a guide rail 821 fixed on the frame 5, and a plurality of sliders 822 corresponding to the plurality of support frames 81 are slidably connected to the guide rail 821, and the sliders 822 are fixedly connected to the corresponding support frames 81; a plurality of rollers 823 are rotatably connected to the sliders 822, and a slide groove 8211 is provided on the guide rail 821, and the rollers 823 slide in the slide groove 8211. A rack 824 is fixed above the guide rail 821, and a gear 825 is rotatably connected to the support frame 81, and the rack 824 and the gear 825 are meshed with each other. A driving motor 826 is also provided at one end of the rotating shaft of the gear 825.

[0059] When the support frame 81 is moved by the moving component 82, the driving motor 826 is started first, and then the driving motor 826 drives the gear 825 to rotate, and under the action of the slider 822 and the rack 824, the gear 825 can drive the support frame 81 and the spray line pipeline 6 to move along the guide rail 821.

[0060] In some embodiments, reference Fig. 9 The height spacing adjustment assembly 83 includes a lifting screw 831 disposed between the support frame 81 and the spray line pipe 6 and a first pipe hoop 832 disposed between the lifting screw 831 and the spray line pipe 6. The first pipe hoop 832 is detachably sleeved on the outside of the spray line pipe 6. One end of the lifting screw 831 is threadedly connected to the support frame 81, and the other end is rotatably connected to the first pipe hoop 832. A guide rod 833 is also disposed between the support frame 81 and the spray line pipe 6. A second pipe hoop 834 is disposed between the guide rod 833 and the spray line pipe 6. The second pipe hoop 834 is detachably sleeved on the outside of the spray line pipe 6. One end of the guide rod 833 is slidably connected to the support frame 81, and the other end is fixedly connected to the guide rod 833. Exemplarily, a tool block 835 is also fixedly disposed on the outside of the lifting screw 831.

[0061] When adjusting the height distance between the spray line pipe 6 and the corrugated paper protrusion by the height spacing adjustment component 83, the staff first rotates the tool block 835 by a wrench or other tool, and the tool block 835 drives the lifting screw 831 to rotate. Since one end of the lifting screw 831 is threadedly connected to the support frame 81 and the other end is rotatably connected to the first pipe hoop 832, the lifting screw 831 will drive the first pipe hoop 832 and the spray line pipe 6 to move up and down. At the same time, under the action of the guide rod 833, the spray line pipe 6 will not rotate, thereby accurately adjusting the distance between the spray line pipe 6 and the corrugated paper protrusion, so that the linear adhesive can be accurately sprayed on the high point protrusion of the corrugated structure, and the processing of corrugated paperboards of different thicknesses can be realized. When the spray line pipe 6 is damaged, blocked or aged, it can be quickly disassembled through the first pipe hoop 832 and the second pipe hoop 834, which is convenient for subsequent maintenance and replacement.

[0062] In some embodiments, reference Fig. 9 The wire feeding mechanism 7 includes a curved pipe 71 arranged at one side of the wire inlet end of the wire spraying pipe 6, the curved pipe 71 is connected to the wire spraying pipe 6; a wire blowing air cavity device 72 is arranged at one end of the curved pipe 71. A pneumatic scissors 73 is also arranged at one side of the wire outlet end of the wire spraying pipe 6.

[0063] When feeding the linear adhesive into the wire spraying pipe 6 through the wire feeding mechanism 7, the wire blowing air cavity device 72 is first started. The wire blowing air cavity device 72 uses the negative pressure principle to suck the linear adhesive into the wire spraying pipe 6 and feed it between two corrugated cardboards from the wire outlet side of the wire spraying pipe 6. When the order needs to be changed, the pneumatic scissors 73 can cut off the linear adhesive. The input side of the wire-bound adhesive always ensures that the wire is in the wire spraying pipe 6. After the wire is used up, there is no need to manually feed the wire into the wire spraying pipe 6 repeatedly, thereby reducing the labor intensity of the staff.

[0064] The implementation principle of the four-layer corrugated paperboard manufacturing equipment with reinforcing ribs in the embodiment of the present application is as follows: when the staff produces the corrugated paperboard, after the base paper is prepared, the base paper is passed through the corrugated roller to form a corrugated corrugated structure, and then the base paper is coated with glue and convex to convex to form a double corrugated corrugated paperboard. At the same time, the height of the spray line pipeline 6 is adjusted by the movable adjustment mechanism 8 to adapt to the thickness of the corrugated paperboard, and under the cooperation of the spray line pipeline 6 and the wire feeding mechanism 7, multiple lines of adhesive are sprayed evenly spaced along the width direction between two sheets of corrugated corrugated paper that have not yet been glued. When the two sheets are When one end of the linear adhesive in the middle of the corrugated paper is pneumatically sprayed into the pressing gap of the pressure roller in the corrugated paper mounting machine, the linear adhesive is continuously fed between two sheets of corrugated paper under the drive of the pressure roller, and the two sheets of corrugated paper are driven forward by the corrugated paper mounting machine. Multiple longitudinal linear adhesives and the corrugated protrusions that are horizontally coated with glue by the gluing mechanism of the corrugated paper mounting machine form a cross "tic-tac-toe shape". Multiple longitudinal linear adhesives act as reinforcing ribs and are pressed into one with the double corrugated corrugated paperboard and dried. Then the double corrugated corrugated paperboard and the face paper 2 are bonded together by the gluing mechanism to form a four-layer corrugated paperboard. Finally, The corrugated board can be cut into the required size by the cutting mechanism; wherein, by the coordinated use of the spray line pipe 6 and the wire feeding mechanism 7, a plurality of linear adhesives can be sprayed uniformly along the width direction of the corrugated board, and the plurality of linear adhesives and the adhesives coated along the corrugated protrusions by the gluing mechanism of the corrugated board mounting machine form cross-shaped reinforcing ribs, thereby replacing the middle lining paper 3 of the five-layer corrugated board, not only achieving the effect of reducing the dosage of adhesive while reducing the use of one layer of lining paper 3, improving the resource utilization rate of raw materials in the production process of the corrugated board, and saving energy and reducing consumption, but also The tic-tac-toe reinforcing ribs ensure that the two layers of double-corrugated cardboards that are glued together do not change in length or flute shape after being stretched, and the flute pitches can remain consistent, so that when the double-corrugated cardboards are glued together, there will be no unbalanced, unstable, or irregular high and low flutes, thereby improving the supporting strength and other physical indicators of the four-layer cardboard; and the movable adjustment mechanism 8 can not only adjust the height of the spray line pipe 6 to adapt to the production of corrugated cardboards of different thicknesses, but also adjust the spacing between two adjacent spray line pipes 6 to adapt to the production of corrugated cardboards of different widths, thereby improving the practicability and adaptability of the equipment.
