Description

Technical Field

[0001] This utility model relates to the technical field of kraft paper composite device, and in particular to a kraft paper double-roll synchronous composite device for packaging paper production. Background Technology

[0002] In the field of packaging paper production, traditional kraft paper laminating equipment mostly adopts a single roll unwinding, step-by-step gluing and pressing operation mode. This mode requires the sequential completion of single-layer paper roll unwinding, adhesive coating, and multiple pressing processes. Not only is the production efficiency limited by the connection rhythm of each link, but the step-by-step operation is also prone to quality defects such as uneven gluing, interlayer air bubbles, and fluctuations in composite strength, making it difficult to meet the modern packaging industry's batch demand for high-precision, high-strength composite paper materials.

[0003] When kraft paper laminating equipment is in use, traditional kraft paper laminating equipment mostly adopts a single roll unwinding, step-by-step gluing and pressing operation mode. Specifically, conventional equipment usually has a single unwinding mechanism. After the kraft paper is transported to the gluing unit by guide wheels to complete single-sided gluing, it is then bonded to another layer of material through an independent pressing mechanism. The process relies on manual or mechanical segmented connection between each process. Although this design can complete the basic lamination requirements when operating a single roll, in large-scale lamination processing scenarios, the unwinding, gluing and pressing processes are connected in sequence, resulting in significant discontinuity in the production process, low equipment utilization, and the ability to process only a single roll of material at a time. This makes it difficult to meet the rigid efficiency requirements of batch production. Especially against the backdrop of rapid expansion in the packaging paper industry, the capacity bottleneck of traditional equipment is becoming increasingly prominent.

[0004] Therefore, to address the issue of hindering the improvement of packaging paper production efficiency when used in large-scale composite processing scenarios, a kraft paper double-roll synchronous composite device for packaging paper production can be designed. When this kraft paper composite device is working, after the two sets of kraft paper are bonded together, they are guided and supported by multiple sets of sliding wheels at the top, and finally enter the winding mechanism. After the winding mechanism is started, the two sets of kraft paper are moved synchronously through continuous winding. Under the squeezing cooperation of the sliding wheels and the pressing wheels, the adhesive layer is fully compacted, achieving tight composite. The composite kraft paper is then neatly wound into the winding mechanism after being guided, completing the double-roll synchronous composite production process. In summary, this device achieves efficient and stable composite through the collaboration of multiple components. The double-roll synchronous unwinding and composite design enables the upper and lower sets of kraft paper to complete the gluing, pressing, and winding processes simultaneously, greatly improving the packaging paper production efficiency, meeting the needs of mass production, and suitable for the large-scale composite processing needs of kraft paper in packaging paper production. Utility Model Content

[0005] To overcome the problem that traditional kraft paper laminating equipment often adopts a single roll unwinding, step-by-step gluing and pressing operation mode, the unwinding, gluing and pressing processes are connected in series, resulting in significant discontinuity in the production process, low equipment utilization, and the fact that it can only process a single roll of material at a time, it is inconvenient to improve the production efficiency of packaging paper when used in large-scale laminating processing scenarios.

[0007] Preferably, when the kraft paper laminating device is working, the kraft paper on the lower unwinding roller is guided by the top of the lower guide wheel and then passes through the bottom of the coating wheel. At this time, the adjusting mechanism drives the coating wheel to keep the coating wheel pressed tightly against the surface of the kraft paper. Simultaneously, the kraft paper on the upper unwinding roller is guided by the bottom of the upper guide wheel and then passes through the bottom of the two sets of pressing rollers. At this time, the pressing rollers are driven to press the upper kraft paper against the glued lower kraft paper. After the two sets of kraft paper are bonded together, they are guided and supported by the tops of multiple sets of sliding rollers and finally enter the winding mechanism. After the winding mechanism is started, it continuously winds the paper. Two sets of kraft paper are moved synchronously. Under the squeezing action of the sliding rollers and the pressing rollers, the adhesive layer is fully compacted, achieving tight lamination. After lamination, the kraft paper is guided and neatly wound onto the winding mechanism, completing the double-roll synchronous lamination production process. In summary, this device achieves efficient and stable lamination through the collaboration of multiple components. The synchronous unwinding and lamination design of the two rolls enables the upper and lower sets of kraft paper to complete the gluing, pressing, and winding processes simultaneously, greatly improving the production efficiency of packaging paper, meeting the needs of mass production, and suitable for the large-scale lamination processing of kraft paper in packaging paper production.

[0009] Preferably, the adjustment mechanism includes a frame, a connecting column, a connector, and a spring. Two sets of frames are fixedly installed on both sides of the platform.

[0013] The beneficial effects of this utility model are:

[0014] 1. When the kraft paper laminating device is working, the kraft paper on the lower unwinding roller is guided by the top of the lower guide wheel and then passes through the bottom of the coating wheel. At this time, the adjusting mechanism drives the coating wheel to keep the coating wheel pressed firmly against the surface of the kraft paper. Simultaneously, the kraft paper on the upper unwinding roller is guided by the bottom of the upper guide wheel and then passes through the bottom of the two sets of pressing rollers. At this time, the driving pressing rollers press the upper kraft paper against the glued lower kraft paper. After the two sets of kraft paper are bonded, they are guided and supported by the top of multiple sets of sliding rollers and finally enter the winding mechanism. After the winding mechanism is started, it continuously winds and pulls the paper. Two sets of kraft paper move synchronously. Under the squeezing action of the sliding rollers and the pressing rollers, the adhesive layer is fully compacted, achieving tight lamination. After lamination, the kraft paper is guided and neatly wound onto the winding mechanism, completing the dual-roll synchronous lamination production process. In summary, this device achieves efficient and stable lamination through the collaboration of multiple components. The dual-roll synchronous unwinding and lamination design enables the upper and lower sets of kraft paper to complete the gluing, pressing, and winding processes simultaneously, significantly improving the production efficiency of packaging paper, meeting the needs of mass production, and suitable for the large-scale lamination processing of kraft paper in packaging paper production.

[0015] 2. Firstly, the gluing wheel adjustment mechanism uses a combination of springs and connectors. Through elastic adaptive adjustment, it ensures that the gluing wheel is always in close contact with the kraft paper surface, guaranteeing uniform glue coating and avoiding problems such as missed coating or excessive thickness. Secondly, the electrically controlled lifting rod controls the lifting and lowering of the pressing wheel, which can flexibly adjust the pressing pressure to adapt to the composite needs of kraft paper of different thicknesses or materials, enhancing the composite bonding strength and quality stability. Thirdly, the squeezing cooperation between the sliding wheel and the pressing wheel forms a double pressing effect. Combined with the continuous traction of the winding mechanism, it allows the glue layer to fully penetrate and bond during dynamic movement, ensuring that the composite interface is free of bubbles and delamination. Fourthly, the overall structure is compact and reasonable, the layout of each component is clear, and operation and maintenance are convenient. Furthermore, the precise guidance of the guide wheel and the discharge wheel ensures a smooth kraft paper transmission path, reducing the risk of wrinkles or deviation. Attached Figure Description

Two sets of brackets 6 are fixedly installed on one side of the platform 1, and two sets of unwinding wheels 7 are rotatably installed between the two sets of brackets 6. Two sets of kraft paper rolls are respectively installed on the upper and lower sets of unwinding wheels 7.

The two ends of the glue-applying wheel 5 are rotatably connected to the inner walls of the two sets of connectors 10 respectively. A spring 11 is fixedly installed between the bottom of the connector 10 and the inner wall of the frame 8. The upper end of the spring 11 is fixedly connected to the bottom of the connector 10, and the lower end of the spring 11 is fixedly connected to the inner wall of the frame 8. The adjustment mechanism at both ends of the glue-applying wheel 5 pushes the connector 10 to slide along the connecting column 9 through the spring 11, so that the glue-applying wheel 5 is always pressed tightly against the surface of the kraft paper.

[0025] Please see Figure 1 and Figure 3 A glue storage tank 12 is installed outside the platform 1, and a feeding pump 13 is fixedly installed on the outer wall of the platform 1. The glue outlet of the glue storage tank 12 is fixedly connected to the feed inlet of the feeding pump 13. A feeding pipe 14 is fixedly installed between the two sets of frames 8. The discharge port of the feeding pipe 14 is located above the coating wheel 5. The feed inlet of the feeding pipe 14 is fixedly connected to the discharge port of the feeding pump 13. The feeding pump 13 transports the glue liquid in the glue storage tank 12 to the coating wheel 5 through the feeding pipe 14. The glue liquid drips onto the rotating coating wheel 5 and is evenly coated on the surface of the kraft paper.

[0026] Please see Figure 2 and Figure 4A support frame 15 is fixedly installed above platform 1. An electrically controlled lifting rod 16 is fixedly installed on the top of the support frame 15. An H-shaped frame 17 is fixedly installed at the telescopic end of the electrically controlled lifting rod 16. Fixed side frames 18 are fixedly installed on both sides above platform 1. Multiple sets of sliding wheels 2 are rotatably connected to the inner walls of the two fixed side frames 18 at both ends.

The H-shaped frame 17 is pushed down along the support column 19 on the fixed side frame 18, which drives the pressing wheel 3 to press the upper kraft paper against the glued lower kraft paper. The sliding cooperation between the H-shaped frame 17 and the support column 19 ensures that the pressing process is smooth and without deviation. Two sets of fixed columns 20 are fixedly set on one side of the platform 1. The two sets of guide wheels 4 are rotatably connected to the inner walls of the two sets of fixed columns 20 at both ends. The discharge wheel 21 is rotatably set on the other side of the platform 1. After being guided by the discharge wheel 21, the laminated kraft paper is neatly wound into the winding mechanism, completing the double-roll synchronous lamination production process.

[0027] When the kraft paper laminating device is working, the working principle of the kraft paper double roll synchronous laminating device for packaging paper production is as follows: When the device is started, two sets of kraft paper rolls are respectively installed on the upper and lower sets of unwinding rollers 7. After the kraft paper on the lower unwinding roller 7 is guided by the top of the lower guide roller 4, it adheres to the bottom of the coating roller 5. At this time, the adjustment mechanism at both ends of the coating roller 5 pushes the connecting piece 10 to slide along the connecting column 9 through the spring 11, so that the coating roller 5 always presses tightly against the surface of the kraft paper. The feeding pump 13 delivers the glue liquid in the glue storage tank 12 to the top of the coating roller 5 through the feeding pipe 14. The glue liquid drips onto the rotating coating roller 5 and is evenly coated on the surface of the kraft paper.

[0028] Meanwhile, the kraft paper on the upper unwinding roller 7 is guided by the bottom of the upper guide roller 4 and then passes through the bottom of the two sets of pressing rollers 3. At this time, the electric lifting rod 16 pushes the H-shaped frame 17 down along the support column 19 on the fixed side frame 18, which drives the pressing rollers 3 to press the upper kraft paper against the glued lower kraft paper. The sliding cooperation between the H-shaped frame 17 and the support column 19 ensures that the pressing process is smooth and without deviation. After the two sets of kraft paper are bonded, they are guided and supported by the top of multiple sets of sliding rollers 2, and then enter the winding mechanism through the top of the discharge roller 21.

[0029] After the winding mechanism is started, the two sets of kraft paper move synchronously by continuous winding. Under the squeezing cooperation of the sliding wheel 2 and the pressing wheel 3, the adhesive layer is fully compacted to achieve tight bonding. After bonding, the kraft paper is guided by the discharge wheel 21 and neatly wound into the winding mechanism to complete the double-roll synchronous bonding production process.

[0030] In summary, this device achieves efficient and stable lamination through the collaborative operation of multiple components. Firstly, the dual-roll synchronous unwinding and lamination design allows the upper and lower sets of kraft paper to simultaneously complete the gluing, pressing, and rewinding processes, significantly improving the production efficiency of packaging paper and meeting the needs of mass production. Secondly, the gluing roller 5 adjustment mechanism uses a combination of spring 11 and connecting piece 10, which ensures that the gluing roller 5 is always in close contact with the kraft paper surface through elastic adaptive adjustment, ensuring uniform glue coating and avoiding problems such as missed coating or excessive thickness. Thirdly, the electrically controlled lifting rod 16 controls the lifting and lowering of the pressing roller 3, which can... The pressure can be flexibly adjusted to adapt to the composite needs of kraft paper of different thicknesses or materials, enhancing the composite bonding strength and quality stability. Fourth, the squeezing action of the sliding wheel 2 and the pressing wheel 3 forms a double pressing effect, which, together with the continuous traction of the winding mechanism, allows the adhesive layer to fully penetrate and bond during dynamic movement, ensuring that the composite interface is free of bubbles and delamination. Fifth, the overall structure is compact and reasonable, with clear layout of each component, convenient operation and maintenance, and the precise guidance of the guide wheel 4 and the discharge wheel 21 ensures a smooth kraft paper transmission path and reduces the risk of wrinkles or deviation.

[0031] In summary, this device achieves simultaneous and efficient lamination of two rolls of kraft paper through mechanical structure optimization and automated control. It has significant advantages such as high production efficiency, good lamination quality, flexible adjustment, and convenient operation, and is suitable for the large-scale lamination processing needs of kraft paper in packaging paper production.

[0032] Through the above steps, when the kraft paper laminating device is working, the kraft paper on the lower unwinding roller 7 is guided by the top of the lower guide roller 4 and then adheres to the bottom of the coating roller 5. At this time, the adjusting mechanism drives the coating roller 5 to keep it pressed tightly against the surface of the kraft paper. Simultaneously, the kraft paper on the upper unwinding roller 7 is guided by the bottom of the upper guide roller 4 and then adheres to the bottom of the two sets of pressing rollers 3. At this time, the pressing rollers 3 are driven to press the upper kraft paper against the glued lower kraft paper. After the two sets of kraft paper are adhered, they are guided and supported by the top of multiple sets of sliding rollers 2, and finally enter the winding mechanism. After the winding mechanism is started, it passes through... The continuous winding pull of the two sets of kraft paper moves synchronously. Under the squeezing cooperation of the sliding wheel 2 and the pressing wheel 3, the adhesive layer is fully compacted to achieve tight lamination. After lamination, the kraft paper is guided and neatly wound into the winding mechanism, completing the double-roll synchronous lamination production process. In summary, this device achieves efficient and stable lamination through the collaboration of multiple components. The double-roll synchronous unwinding and lamination design enables the upper and lower sets of kraft paper to complete the gluing, pressing, and winding processes simultaneously, which greatly improves the production efficiency of packaging paper, meets the needs of mass production, and is suitable for the large-scale lamination processing needs of kraft paper in packaging paper production.
