DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment

[0034] See Figures 1 to 4As shown in the figure, a rewinding structure for paper yarn processing includes a break self-checking structure 1, a comb-shaped material distributing structure 2, and a winding device 3. The slit paper yarns pass through the break self-checking structure and the comb-shaped material distributing structure in sequence and then enter the winding device. The comb-shaped material distributing structure includes a support 21, a guiding shaft roller 22, and a support rod 23. Comb teeth 24 are arranged on the top surface of the support rod. During use, the paper yarn strips are guided by different comb teeth to ensure that there is no connection between each paper yarn, guaranteeing the effectiveness and smoothness of subsequent winding.

[0035] In this embodiment, the winding device includes a bracket 31, a front guide wheel 32, a rear guide wheel 33, a tension adjusting structure 34, a pressure adjusting structure 35, a rubber-coated pressing wheel 36, and a rewinding shaft structure 37 arranged on the bracket. During assembly, the tension adjusting structure is located below the front guide wheel and the rear guide wheel, and the pressure adjusting structure is located between the rear guide wheel and the rubber-coated pressing wheel. During use, the paper yarn passes through the front guide wheel, the tension adjusting structure, the rear guide wheel, the pressure adjusting structure, the rubber-coated pressing wheel in sequence and is then rewound by the rewinding shaft structure. The tension adjusting structure can be used to adjust the transmission tension of the paper yarn, ensuring the smoothness of the paper yarn transmission and also ensuring that the paper yarn is in a tensioned state during transportation. The front guide wheel, the rear guide wheel, and the rubber-coated pressing wheel are all conventional structures of the prior art. The rubber-coated pressing wheel mainly cooperates with the rewinding shaft structure to achieve tight rewinding.

[0036] Moreover, in this embodiment, the tension adjusting structure 34 includes a detection shaft 341, a tension swing rod 342, and a counterweight wheel 342. During assembly, the detection shaft is rotatably connected to the bracket. The counterweight wheel is located at one end of the tension swing rod, and the other end of the tension swing rod is connected to the detection shaft. The counterweight wheel is located below the gap between the front guide wheel and the rear guide wheel. The paper yarn passing through the front guide wheel is connected to the rear guide wheel after passing through the counterweight wheel. The detection shaft rotates to lift and lower the counterweight wheel through the tension swing rod to achieve tension adjustment.

[0037] Moreover, in this embodiment, the pressure adjustment structure 35 includes an adjustment wheel disc 351, an adjustment spring 352, a swing arm 353, and a multi-groove guide wheel 354. In this embodiment, the multi-groove guide wheel is provided with guide grooves of various specifications and different widths, so as to meet the guiding requirements of different paper yarns. During assembly, the adjustment wheel disc is rotatably connected to the bracket; the adjustment spring is sleeved on the shaft rod of the adjustment wheel disc, and one end of the adjustment spring abuts against the bracket; one end of the swing arm is fixed on the adjustment wheel disc, and the multi-groove guide wheel is rotatably connected to the end of the swing arm; the multi-groove guide wheel is located between the rubber-coated pressing wheel and the rear guide wheel; the paper yarn passing through the rear guide wheel enters the rewinding shaft structure through the multi-groove guide wheel and then through the rubber-coated pressing wheel. The multi-groove guide wheel and the rubber-coated pressing wheel are installed on the swing arm. When working, the rubber-coated pressing wheel transmits force to the swing arm through the adjustment spring, and finally presses tightly on the winding rubber cylinder of the quick-release chuck in real time and follow-up; and the pressing force can be adjusted in multiple levels through the adjustment spring, and different paper yarns or winding rubber cylinders can adopt different pressing forces. When it is necessary to replace the winding rubber cylinder, the pre-tightening force of the adjusting spring can be released, and the swing arm and the rubber-coated pressing wheel and the multi-groove guide wheel installed on the swing arm can be adsorbed onto the magnet of the adsorption module, which is convenient for replacement operation and improves the usability;

[0038] During the actual application process, a magnet adsorption block 4 is arranged between the rear guide wheel and the multi-groove guide wheel.

[0039] In this embodiment, the rewinding shaft structure includes a rewinding drive disc 371, a rewinding shaft rod 372, a limit ring 373, a winding rubber cylinder 374, a clamping ring 375, a spring 376, and a locking sleeve 377. During processing and assembly, the rewinding drive disc is connected to the rewinding motor through a belt, and the rewinding shaft rod is fixed at the center of the rewinding drive disc; the winding rubber cylinder is sleeved on the rewinding shaft rod and is limited at both ends by the limit ring and the clamping ring respectively. The locking sleeve is sleeved on the rewinding shaft rod and is locked by a screw, and the spring is located between the locking sleeve and the clamping ring. Replacement can be achieved through the locking sleeve, the clamping ring, the spring, and the limit ring. When replacing, first install the limit ring, then sleeve the winding rubber cylinder, and then insert the clamping ring, the spring, and the locking sleeve. The clamping ring, the spring, and the locking sleeve are a set of integrated structures and are fixedly connected together.

[0040] During operation, first manually rotate the rewinding shaft rod to roughly position the counterweight wheel horizontally through the paper yarn, and then start the rewinding shaft to begin the rewinding motion. The working principle is briefly described as follows: The angle of the detection shaft is collected in real time and fed back to the control system. The control system judges the magnitude of the detection shaft angle. When the detected angle is greater than 45°, the rewinding motor is controlled by the driver to decelerate, then the tension swing rod rotates counterclockwise, the angle of the tension swing rod decreases, and the detection shaft angle is smaller, and vice versa. Different paper yarns use different tensions, and a counterweight wheel can be designed on the left side of the tension swing rod to achieve pre-tensioning of the paper yarn. Its control system is set on the slitting structure, so it is not described in detail. It is mainly used to control and drive each structure.

[0041] The present invention has positive effects: The structure of the present invention is reasonably arranged, including a fracture self-checking structure, a comb-shaped material distribution structure and a winding device, making each structure modular, facilitating rapid assembly and maintenance operations, and it includes a tension adjustment structure and a pressure adjustment structure, so that dynamic tension adjustment of the paper yarn can be realized to ensure the effectiveness and smoothness of the paper yarn transmission, and through the pressure adjustment structure, multi-stage pressure adjustment of the paper yarn at the winding place can be carried out, so that the effectiveness and reliability of winding can be ensured, it is more convenient to use, and it can also meet the usage requirements in different situations, with strong applicability;

[0042] And the pressure adjustment structure includes an adjustment wheel disc, an adjustment spring, a swing arm and a multi-groove guide wheel. Through the multi-groove guide wheel, guiding of different slitting paper yarn widths can be realized, greatly improving the convenience while enhancing the reliability, with strong applicability.

[0043] The standard parts used in this embodiment can be directly purchased from the market, and the non-standard structural components described in the specification can also be directly processed without doubt according to the existing technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology, so no specific description will be made here.

[0044] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limitations on the implementation modes of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation modes here. And these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
