[0063] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0064] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0065] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention. Example

[0066] See also Figures 1-5 As shown, a roll-up machine is designed to automate the process of rolling cloth onto a paper roll, significantly improving the quality and efficiency of the cloth winding process. The roll-up machine comprises two winding rollers 1 rotating in the same direction, with a cloth conveyor 2 disposed outside the winding rollers 1. The cloth conveyor 2 is used to convey the cloth onto the winding rollers 1, and a cross-cutting mechanism 3 is provided on the cloth conveyor 2 for cutting the cloth. The roll-up machine also includes a paper roll loading mechanism, a paper roll loading platform 5, and a winding mechanism 7. Specifically:

[0067] The paper tube feeding mechanism includes a paper tube conveyor 4 driven by a first motor. Baffles 41 are arranged at intervals on the transmission chain of the paper tube conveyor 4. Two adjacent baffles 41 together form an area for placing the paper tube, ensuring that the paper tube is firmly positioned during transportation and will not roll or deflect.

[0068] One end of the paper tube conveyor 4 is located above the paper tube loading platform 5. When the paper tube is conveyed to this position, the paper tube on the paper tube conveyor 4 can fall onto the paper tube loading platform 5, achieving a seamless transition from the paper tube conveying stage to the paper tube loading preparation stage. A pushing mechanism 6 is provided on one side of the paper tube loading platform 5 for pushing the paper tube on the paper tube loading platform 5 into the winding mechanism 7.

[0069] Combine Figure 7 、 Figure 8 As shown, a reversible positioning member 51 is located below the paper roll loading platform 5. This positioning member 51 has two sets of side-by-side prongs 511 and is fixed to a rotating shaft 52 driven by a servo motor. When the paper roll needs to be stopped, the positioning member 51 is driven horizontally, with the upper ends of the prongs 511 exposed above the paper roll loading platform 5, and the paper roll is positioned precisely between the two sets of prongs. When the paper roll needs to be pushed, the positioning member 51 moves downward, and the prongs 511 sink to below the paper roll loading platform 5, without affecting the paper roll's rolling motion.

[0070] The winding mechanism 7 can be moved back and forth between the feeding station and the winding station under the drive of the first lifting mechanism 8. When the winding mechanism 7 is located at the feeding station, it can receive the paper tube pushed from the paper tube feeding platform 5. Then, under the drive of the first lifting mechanism 8, the winding mechanism 7 moves downward together with the paper tube to the winding station. The winding mechanism 7 is provided with a hopper 71 for placing the paper tube, and the bottom of the hopper 71 can be opened to drop the paper tube in the hopper 71 to the space between the two winding rollers 1 below the winding station, so as to prepare for the subsequent winding operation.

[0071] The winding mechanism 7 is provided with a rotating assembly and an arm swinging assembly 73, the rotating assembly is used to drive the arm swinging assembly 73 to rotate along a predetermined track, and the arm swinging assembly 73 includes a pair of arms 731 capable of lifting movement, and a pushing rod 74 is arranged between the arms 731, the pushing rod 74 can be driven by the rotating assembly and the arm swinging assembly 73 to move upward along the arc of the periphery of the paper tube, so that the cloth is preliminarily wound on the paper tube.

[0072] The winding machine is provided with an electric control box, and a PLC controller is integrated in the electric control box. The cooperation between the plurality of components is controlled by the program, so as to realize the automatic feeding of the paper tube, the winding positioning and the winding operation on the paper tube, realize the automatic operation of winding the cloth on the paper tube, and improve the winding quality and efficiency of the cloth.

[0073] Further, in order to ensure that the paper tube falls accurately and stably from the paper tube conveyor 4 to the paper tube feeding platform 5, a pair of guide plates 9 are carefully arranged between the paper tube conveyor 4 and the paper tube feeding platform 5. The pair of guide plates 9 can guide the single paper tube to fall stably, and avoid the paper tube from deviating or being stuck during the falling process.

[0074] The pushing mechanism 6 is mainly composed of a pushing cylinder 61 and a pushing block 62. The pushing cylinder 61 serves as a power source, and the piston end thereof is stably connected with the proximal end of the pushing block 62, and the distal end of the pushing block 62 is connected with one of the guide plates 9. Of course, the pushing cylinder 61 can be replaced by an electric push rod or other equivalent implementation structures capable of realizing linear reciprocating motion.

[0075] The openings of the pair of guide plates 9 are large at the top and small at the bottom. The pushing operation of the pushing cylinder 61 can effectively prevent the paper tube from unexpectedly retreating or sliding out from the side during the pushing process. When the pushing cylinder 61 returns to the initial state, the gap therebetween is just enough to allow the single paper tube to fall smoothly, which provides stable guarantee for the subsequent pushing and winding processes.

[0076] In the embodiment, the first lifting mechanism 8 has the function of stably and accurately driving the movement of the winding mechanism 7, and includes a lifting base plate 81, which provides a stable mounting basis for the entire lifting mechanism.

[0077] The lifting cylinder 82 is a core power source for driving the movement of the winding mechanism 7, and the piston end thereof is fixedly connected with the winding mechanism 7. Under the action of the lifting cylinder 82, the winding mechanism 7 can smoothly move back and forth between the feeding station and the winding station. It is worth mentioning that the lifting cylinder 82 can also use an electric push rod, a hydraulic cylinder or other equivalent implementation structures capable of realizing linear reciprocating motion.

[0078] The telescopic end of the gas spring 83 is also connected with the winding mechanism 7, which plays a role in buffering and auxiliary support during the movement of the winding mechanism 7, can effectively reduce vibration and impact, and ensure the stability of movement.

[0079] The slider on the linear slide rail 84 is fixed on the winding mechanism 7, which provides accurate guidance for the movement of the winding mechanism 7, ensures that it does not deviate during movement, and always runs along the predetermined trajectory. Through the cooperation of the lifting cylinder 82, the gas spring 83 and the linear slide rail 84, the first lifting mechanism 8 can reliably drive the winding mechanism 7 to complete various actions.

[0080] In the embodiment, the winding mechanism 7 includes a winding base plate 76, and a pressing roller 75 is pivotally arranged at the lower end of the winding base plate 76. During winding, the pressing roller 75 can apply appropriate pressure to the cloth and the paper tube, ensuring that the winding is tight and neat.

[0081] A hopper 71 is arranged on one side of the winding base plate 76 for placing the paper tube. The rotating assembly arranged on the winding base plate 76 is a key power transmission part. The second motor is in transmission connection with a rotating drive shaft 721, the rotating drive shaft 721 is stably fixed on the winding base plate 76 by means of a bearing seat, and the two ends thereof are fixedly connected with one end of a rotating arm 722, respectively. The swing arm assembly 73 is installed on the rotating arm 722, thus forming a complete rotating drive system.

[0082] In order to further optimize the mechanical transmission, a rack 723 is arranged on the lifting base plate 81 in the same direction as the lifting cylinder 82. A first gear 724 is installed on the rotating drive shaft 721, and a second gear 725 in meshing transmission with the rack 723 is arranged on the winding base plate. At the same time, a transmission gear 726 connecting the first gear 724 and the second gear 725 is also arranged on the winding base plate. Through the meshing transmission between the gears, efficient transmission and conversion of power are realized.

[0083] The second gear 725 is arranged on a second drive shaft 727, and the second drive shaft 727 is fixed on the winding base plate 76 by means of a bearing seat. The transmission gear 726 is arranged on a short shaft, and the short shaft is also fixed on the winding base plate 76 by means of a bearing seat, so as to ensure the stable rotation of the components.

[0084] In this embodiment, the swing arm assembly 73 includes two electric push rods 732, respectively arranged on the corresponding rotating arms 722, and the telescopic ends of the electric push rods are fixedly connected with the swing arm 731 through a connecting piece. The swing arm 731 can be flexibly controlled to rise and fall through the telescopic movement of the electric push rods, so as to meet different winding requirements.

[0085] In use, as shown in Figure 6 , the winding machine operates according to the following winding method:

[0086] Step 1: Place the paper tube on the paper tube conveyor 4 stably. With the transmission of the paper tube conveyor 4, the paper tube will be accurately dropped onto the paper tube loading platform 5, and then wait for the first lifting mechanism 8 to act, and move the winding mechanism 7 to the loading station.

[0087] Step 2: When the winding mechanism 7 is accurately moved to the loading station under the drive of the first lifting mechanism 8, the pushing mechanism 6 is immediately started to push the paper tube into the hopper 71 of the winding mechanism 7. Then, under the continuous drive of the first lifting mechanism 8, the winding mechanism 7 carrying the paper tube stably moves down to the winding station.

[0088] Step 3: After the winding mechanism 7 moves to the winding station, the toggle lever 74 on the winding mechanism 7 first moves down in order between the two winding rollers 1, and at the same time, the cloth is accurately moved to the two winding rollers 1 under the drive of the cloth conveyor 2, and at this time, the toggle lever 74 is just below the cloth.

[0089] Step 4: The hopper 71 on the winding mechanism 7 is timely opened, and the paper tube in the hopper 71 naturally falls on the cloth and rolls to between the two winding rollers 1 under the action of gravity.

[0090] Step 5: The rotating assembly and the swing arm assembly 73 work cooperatively to drive the toggle lever 74 to move upward along the arc-shaped periphery of the paper tube, and skillfully make the cloth preliminarily wound on the paper tube. Among them, Figures 1 to 4 is the winding track of the toggle lever 74.

[0091] Step 6: The two winding rollers 1 are quickly started to tightly wind the cloth on the paper tube. During the winding process, the pressing roller 75 on the winding mechanism 7 applies appropriate pressure to the paper tube, which plays a good pressing role and ensures the winding quality.

[0092] Step 7: When the cloth conveyor 2 conveys the preset length of cloth, the cloth conveyor 2 immediately stops conveying the cloth, the cross-cut mechanism 3 is quickly started to accurately cut the cloth, and the two winding rollers 1 are delayed to stop running, so as to ensure that the cut cloth is completely wound on the paper tube, and a complete winding operation is completed.

[0093] The present application achieves efficient automatic operation through the synergistic operation of the carefully designed components. The paper tube conveyor 4 cooperates with the paper tube loading platform 5 to realize automatic feeding of the paper tube, wherein the paper tube conveyor 4 can also be replaced by a chain plate conveyor or the like. The material winding mechanism 7 is precisely positioned under the driving of the first lifting mechanism 8, cooperates with the rotating assembly and the swing arm assembly 73 to complete the winding positioning and preliminary winding. The two winding rollers 1 cooperate with the cloth conveyor 2, the cross-cut mechanism 3 and the like to complete the final winding and cutting. The components are closely matched, effectively reducing manual intervention, greatly improving the automation degree of the paper tube winding cloth, and significantly improving the winding quality and efficiency of the cloth.
