Description

Technical Field

[0001] The present invention belongs to the technical field of paper yarn processing, and particularly relates to a swing-type tension adjustment structure and method. Background Art

[0002] Paper yarn is a green and environmentally friendly yarn extracted from renewable lignocellulosic biomass, similar to papermaking technology. Its processing process is simple, and no harmful substances are produced. Moreover, paper yarn can be naturally biodegradable after use, thus achieving the purpose of environmental protection. It has many advantages and is widely used in the textile field. At the same time, it also has the advantages of convenient preparation, moisture absorption, air permeability, wear resistance, and wash resistance, and is applied to handicrafts, clothing ornaments, and household items. The prior art includes an unwinding structure, a slitting structure, and a rewinding structure. There is no corresponding structure for adjusting the tension of paper yarn between the unwinding unit and the slitting unit of the prior art. Therefore, it is difficult to ensure sufficient tension when the paper yarn is being transported, which is not conducive to subsequent slitting processing and difficult to meet the market demand.

[0023] 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 work shall fall within the protection scope of the present invention.

[0024] Embodiment

[0025] See Figures 1 to 2 As shown, a swing - type tension adjustment structure is provided on the slitting support plate 1, including an angle detection module 2, an adjustment cylinder 3, a connecting rod 4, and a tension roller 5. During assembly, the angle detection module is arranged on the slitting support plate, the adjustment cylinder is rotatably connected to the slitting support plate through a shaft body, and the piston rod is connected to the middle of the connecting rod. The end of the connecting rod is fixed on the angle detection module, and the tension roller is connected to the end of the connecting rod. Moreover, the paper yarn of the unwinding unit 6 passes through the tension roller and then is fed onto the conveying roller on the slitting support plate for conveyance. During adjustment, the telescopic movement of the adjustment cylinder drives the connecting rod to rotate on the angle detection module, so that the paper yarn on the conveying roller is tightened. Through the above - mentioned structure, the tension adjustment of the paper yarn can be effectively realized, thus ensuring the effectiveness and stability of subsequent slitting.

[0026] Moreover, in this embodiment, the angle detection module includes an encoder 21 and a connecting shaft 22. The encoder is a conventional structure of the prior art and is simply applied. The connecting shaft is connected to the slitting support plate through the encoder, and the end of the connecting rod is fixed on the connecting shaft. Both the adjustment cylinder and the encoder are connected to the control circuit board inside the slitting support plate. The main principle is that the swing - type adaptive mechanism controls the tension of the paper yarn between the unwinding and slitting units. The cylinder provides a pre - tension force. During operation, the angle of the swing roller is detected and fed back to the control system. The control system dynamically adjusts the unwinding and slitting speeds according to the feedback angle and combines with the pre - tension force of the cylinder, thereby dynamically adjusting the tension of the paper yarn to ensure that the tension is stable within the specified range, and the pre - tension force of the cylinder can be adjusted as needed.

[0027] The present invention has positive effects: The structure of the present invention is reasonably arranged. Through the angle detection module, the adjustment cylinder, the cooperation of the connecting rod and the tension roller, the tension adjustment of the paper yarn conveyance can be effectively realized, thereby improving the smoothness and stability of the paper yarn conveyance. Moreover, it is stable and reliable in use, can meet the paper yarn slitting requirements in different situations, and has strong applicability.

[0028] Such as Figure 3 As shown, the second technical solution for realizing the purpose of the present invention: A swing - type tension adjustment method includes the following steps:

[0029] Step A: The paper yarn of the unwinding unit passes through the tension roller and then is fed onto the conveying roller on the slitting support plate for conveyance.

[0030] Step B: Control the slitting speed and the unwinding speed. The slitting speed is greater than or less than the winding speed. The angle of the encoder is fed back to the control circuit board in real time. The control circuit board controls the telescopic length of the adjustment cylinder and drives the connecting rod to swing and adjust, so that the paper yarn tension becomes larger and the paper yarn is tightened.

[0031] Step C: When the connecting rod swings to the target position and the tension reaches the preset value, the unwinding speed can be protected to be consistent with the slitting speed.

[0032] Specifically, during the working process, the angle of the connecting rod is controlled between the left limit and the right limit, so that it swings between the left and right limits with the target position as the center. The adjustment method is as follows:

[0033] When the connecting rod exceeds the left limit, the tension is too small. The control system reduces the unwinding speed, adjusts the cylinder to retract, and the connecting rod moves towards the right limit direction. The tension gradually increases. When the connecting rod moves to the target position, the unwinding speed is equal to the given slitting speed.

[0034] When the connecting rod exceeds the right limit, the tension is too large. The control system increases the unwinding speed, adjusts the cylinder to extend, and the connecting rod moves towards the left limit direction. The tension gradually decreases. When the connecting rod moves to the target position, the unwinding speed is equal to the given slitting speed.

[0035] The method provided by the present invention is simple and is conducive to improving the adjustment efficiency.

[0036] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification, they 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 machinery, parts and equipment all adopt the conventional models in the existing technology. Therefore, no specific description will be made here.

[0037] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or variations derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
