Description

Technical Field

[0001] This utility model relates to the technical field of cushioning paper pad processing equipment, specifically to a cushioning paper pad forming mechanism. Background Technology

[0002] The gap between the goods and the cardboard box or container used to transport them is usually filled with lining material to provide cushioning for the goods and prevent them from moving around inside the carton during transportation. Filling materials include corrugated cardboard, foam padding, and pleated paper padding. Corrugated cardboard production requires sophisticated equipment and involves complex processes; foam padding is expensive to produce and pollutes the environment when used in large quantities; pleated paper padding production currently lacks automated processing machinery with good finished products, and is mostly done manually. The manual folding and creasing of pleated paper padding results in poor cushioning, and the haphazard methods cannot guarantee compliance with strict packaging requirements. Furthermore, it requires a large amount of labor, has low production efficiency, a high defect rate, and creates management inconvenience. This is the main reason why many packaging box manufacturers prefer foam padding.

[0003] In a published Chinese patent application (publication number CN210706287U), titled "A Cushioning Paper Pad Forming Machine," the prior art involves sequentially separating and folding layers of a roll of paper, processing wrinkles, and forming and cutting it using a paper guiding device, a forming device, and a cutting device. While this prior art addresses the aforementioned problems, it still has certain limitations in practical implementation. Specifically, it uses a gear set to irregularly fold the three layers to form a cushioning paper pad. However, the cushioning paper pad produced by this prior art tends to flatten and return to its original shape during use, resulting in poor cushioning performance. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0031] Please see Figures 1 to 9 The present invention provides a technical solution: a cushioning paper pad forming mechanism, including a support frame 1, a first paper roll 5, and a second paper roll 6. The support frame 1 includes a first gantry frame 101, a second gantry frame 102, and two support plates 104. The two ends of the support plates 104 are fixedly installed to the first gantry frame 101 and the second gantry frame 102 respectively, and the two support plates 104 are parallel to each other.

[0032] The first gantry frame 101 includes at least one crossbeam and two uprights, with both ends of the crossbeam fixedly installed to the two uprights respectively. The second gantry frame 102 has the same structure as the first gantry frame 101. Both ends of the support plate 104 are fixedly installed to the uprights in the first gantry frame 101 and the second gantry frame 102 respectively. The first paper roll 5 and the second paper roll 6 refer to rolls of raw material paper (including but not limited to kraft paper, etc.) used for processing cushioning paper pads.

[0033] The first paper roll 5 and the second paper roll 6 are rotatably mounted on the second gantry 102. A crushing assembly and a pressing assembly are mounted on two support plates 104. A traction assembly is mounted on the second gantry 102. The free ends of the paper in the first paper roll 5 are sequentially passed through the crushing assembly and the pressing assembly. The crushing assembly crushes the paper in the first paper roll 5, causing it to fold and wrinkle. The free ends of the paper in the second paper roll 6 are sequentially passed through the traction assembly and the pressing assembly. The traction assembly pulls the paper in the second paper roll 6. The pressing assembly crushes and combines the paper in the second paper roll 6 and the paper in the first paper roll 5 into a cushioning pad.

[0034] In this process, the first paper roll 5 is folded by a pressing component, and the pressing component pulls and pushes the folded paper of the first paper roll 5 towards the pressing component. The pulling component pulls and pushes the paper of the second paper roll 6 towards the pressing component, resulting in a stack of folded paper and second paper roll 6. The pressing component then presses and merges the stacked folded paper and second paper roll 6 together, thus forming a cushioning paper pad. (Cushioning paper pad reference) Figure 9 The cushioning paper pad consists of a flat paper layer 18 and a creased paper layer 19. The paper of the second paper roll 6 is flat paper layer 18 after being rolled and combined. The paper of the first paper roll 5 is creased paper after being rolled by the rolling component. The creased paper is creased paper layer 19 after being rolled and combined by the pressing component.

[0035] Specifically, the support frame 1 also includes four brackets 103, which are fixedly installed on the second gantry frame 102, with each pair of brackets 103 arranged horizontally side by side. The first paper roll 5 and the second paper roll 6 are both rotatably mounted on the brackets 103.

[0036] In this configuration, a shaft passes through the center of either the first paper roll 5 or the second paper roll 6. The bracket 103 supports the shaft of either the first paper roll 5 or the second paper roll 6. When the free end of the paper in the first paper roll 5 or the second paper roll 6 is pulled, the first paper roll 5 or the second paper roll 6 rotates on the bracket 103 around the shaft, thereby unfolding the paper.

[0037] Specifically, the rolling assembly includes a second servo motor 3, a first folding roller 14, and a second folding roller 15. Both ends of the first folding roller 14 are rotatably connected to two support plates 104, and both ends of the second folding roller 15 are also rotatably connected to the two support plates 104. The second servo motor 3 is fixedly mounted on the support plate 104, and its output shaft is drive-connected to one end of the second folding roller 15. The first folding roller 14 and the second folding roller 15 are drive-connected.

[0038] The second servo motor 3 drives the second crease roller 15 to rotate. After the second servo motor 3 is started, its output shaft drives the second crease roller 15 to rotate, which in turn drives the first crease roller 14 to rotate. The first crease roller 14 and the second crease roller 15 rotate in opposite directions. The free end of the paper in the first paper roll 5 is passed between the first crease roller 14 and the second crease roller 15. When the first crease roller 14 and the second crease roller 15 rotate, they crush the paper in the first paper roll 5 located between them. At the same time, the first crease roller 14 and the second crease roller 15 pull the paper in the first paper roll 5, causing the first paper roll 5 to rotate.

[0039] Specifically, the outer walls of the first pleating roller 14 and the second pleating roller 15 are fixedly connected with multiple protruding strips, and a groove is formed between two adjacent protruding strips. The protruding strips on the first pleating roller 14 engage with the grooves of the second pleating roller 15.

[0040] During the rotation of the first crease roller 14 and the second crease roller 15, the paper is creased after being crushed due to the cooperation of the raised strips and grooves. That is, the crushed paper is creased paper.

[0041] Specifically, the traction assembly includes a second rotating roller 7, a first rotating roller 16, and a third servo motor 4. The two ends of the second rotating roller 7 are rotatably connected to the second gantry frame 102, the two ends of the first rotating roller 16 are rotatably connected to the second gantry frame 102, and the third servo motor 4 is fixedly mounted on the second gantry frame 102. The output shaft end of the third servo motor 4 is drivenly connected to one end of the first rotating roller 16, and the first rotating roller 16 is drivenly connected to the second rotating roller 7.

[0042] In this configuration, the free end of the paper in the second paper roll 6 is inserted into the gap between the first rotating roller 16 and the second rotating roller 7. After the third servo motor 4 is started, the output shaft of the third servo motor 4 drives the first rotating roller 16 to rotate, and the first rotating roller 16 drives the second rotating roller 7 to rotate. The first rotating roller 16 and the second rotating roller 7 rotate towards each other and crush the paper in the second paper roll 6. At the same time, the first rotating roller 16 and the second rotating roller 7 pull the paper in the second paper roll 6, causing the paper in the second paper roll 6 to unfold and move, and the second paper roll 6 rotates.

[0043] Specifically, the pressing assembly includes a first servo motor 2, a first pressing roller 11, and a second pressing roller 9. The two ends of the first pressing roller 11 are rotatably connected to two support plates 104, and multiple protruding strips are fixedly connected to the outer side wall of the first pressing roller 11. The two ends of the second pressing roller 9 are rotatably connected to the two support plates 104, and the first servo motor 2 is fixedly mounted on the support plate 104, with its output shaft end being drive-connected to one end of the first pressing roller 11. The first pressing roller 11 and the second pressing roller 9 are drive-connected.

[0044] A first support plate 10 and a second support plate 17 are fixedly installed on two support plates 104, respectively. The first support plate 10 is located between the rolling assembly and the pressing assembly, and is used to support the creased paper. The creased paper moves above the first support plate 10 to the pressing assembly. The free ends of the paper and the creased paper of the second paper roll 6 are stacked one on top of the other and pass through the gap between the first pressing roller 11 and the second pressing roller 9. After the first servo motor 2 is started, the output shaft of the first servo motor 2 drives the first pressing roller 11 to rotate, and the first pressing roller 11 drives the second pressing roller 9 to rotate. The first pressing roller 11 and the second pressing roller 9 rotate towards each other and crush the stacked paper and creased paper of the second paper roll 6, so that the paper and creased paper of the second paper roll 6 are stuck together. During the pressing process, the raised strip of the first pressing roller 11 is located in the crease groove on the lower surface of the crease paper, thereby preventing the first pressing roller 11 from damaging the creases on the crease paper and ensuring that the paper of the second paper roll 6 and the crease paper are adhered. The buffer paper pad formed after the paper of the second paper roll 6 and the crease paper are adhered is removed by the first support plate 10.

[0045] Specifically, an auxiliary frame 8 is fixedly installed on the support frame 1. A rubber tube 12 and a support rod 13 are respectively installed on the auxiliary frame 8. The support rod 13 is parallel to the rubber tube 12. The free ends of the second paper roll 6 are wound around the support rod 13 and the rubber tube 12. Multiple through holes are opened in the wall of the rubber tube 12. A glue box is installed above the auxiliary frame 8, containing adhesive. A conduit is installed on the bottom wall of the glue box, and the two are connected. The end of the conduit away from the glue box is fixedly installed and connected to the rubber tube 12. A throttling valve is installed on the conduit.

[0046] The support rod 13 is used to lift the paper in the second paper roll 6 and guide it. The adhesive box holds the adhesive, which flows through a conduit into the adhesive tube 12. The adhesive tube 12 is used to apply adhesive to the paper in the second paper roll 6. The adhesive in the adhesive tube 12 seeps out through various through-holes. As the paper in the second paper roll 6 moves on the adhesive tube 12, the adhesive seeping out of the tube 12 is brushed onto the lower surface of the paper. After being coated with adhesive, the paper can effectively adhere to the wrinkled paper, making the two stick together tightly. The throttle valve is used to regulate the flow rate of the fluid in the conduit.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
