Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a tensioner of a winding machine. Background Art

[0002] The tensioner of the winding machine plays a key role in the winding process. The main function of the tensioner is to control the tension of the silk thread and ensure that the silk thread maintains the appropriate tightness during the winding process. The appropriate tension is crucial to the quality of the silk thread, the uniformity of the winding, and the subsequent processing.

[0003] During the tension adjustment process, if the tension is too high, the wire may be broken or damaged, affecting product quality; if the tension is too low, the wire may not be tightly wound, and may become loose or messy. The role of the tensioner is to accurately adjust and control the tension of the wire according to the process requirements to keep it in the best state. However, the direction of the wire entering and exiting many tensioners is difficult to adjust, and the inlet and outlet will squeeze the wire, which will also cause the squeezed wire to break under the action of the tensioner. Therefore, improvements are proposed on this basis. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 The utility model provides a technical solution: a tensioner for a winding machine, comprising a base plate 1, on which two arc-shaped sliding openings 2 arranged opposite to each other are opened, and inside the two arc-shaped sliding openings 2 are arranged adjustment frames 3 capable of adjusting directions, and the two adjustment frames 3 are used for thread penetration;

[0027] A tension adjustment component 4 is provided on the front side of the substrate 1, and the tension adjustment component 4 is used to control the tension of the thread.

[0028] The adjustment frame 3 includes an adjustment plate 31, a rotatable control ring 36, and a transmission inner wheel 38 installed inside the control ring 36;

[0029] A through hole 32 is provided on the end face of the adjustment plate 31, and an adjustment cavity 33 is provided on the outer side of the adjustment plate 31 coaxially with the through hole 32. The diameter of the adjustment cavity 33 is larger than that of the through hole 32. The control ring 36 is clamped in the adjustment cavity 33. A clamping frame 37 is fixed on the inner side of the control ring 36. The transmission inner wheel 38 is rotatably mounted on the clamping frame 37. The transmission inner wheel 38 is located in the through hole 32, and the transmission inner wheel 38 is located on the outside of the axis of the through hole 32. The transmission inner wheel 38 is located on the outside of the axis of the through hole 32. Therefore, during the change of the silk thread transmission direction, the transmission inner wheel 38 can move with the movement to a suitable position to avoid the silk thread from falling off.

[0030] A fastening bolt 34 is also fixed to the side of the adjustment plate 31, and the fastening bolt 34 extends into the arc-shaped sliding port 2, and the end of the fastening bolt 34 is also threadedly connected with a fastening nut 35 for fastening. The fastening bolt 34 and the fastening nut 35 are matched directly to facilitate direct matching, so that the position and direction of the adjustment plate 31 can be adjusted.

[0031] Two sets of opposite transmission wheels 5 are also rotated on the front of the base plate 1, and the transmission wheels 5 are used for winding the yarn;

[0032] The tension adjustment assembly 4 comprises a rotatable driving shaft 41 , an adjusting wheel 42 is fixed to the end of the driving shaft 41 , and the yarn is respectively wound around the two sets of transmission wheels 5 and the adjusting wheel 42 and extends out.

[0033] The front of the base plate 1 is also provided with an inverted triangle opening 11 and a plurality of control holes 12. The plurality of control holes 12 are located on both sides of the inverted triangle opening 11 and are arranged in an inclined manner. The front and rear surfaces of the base plate 1 are also fixed with supporting longitudinal rods 13.

[0034] Two groups of support cross bars 43 for clamping are sleeved on the outer wall of the driving shaft 41. The two groups of support cross bars 43 cooperate with the support longitudinal bars 13 on the base plate 1 to realize that the support cross bars 43 can only move longitudinally. Clamping blocks 45 are slidably provided on both sides of the inverted triangular opening 11. Limited position marks 47 are fixed on the front and rear sides of the clamping blocks 45. The limit marks 47 set at the front and rear clamp the two groups of support cross bars 43 at the front and rear, and limit the clamping blocks 45 so that the clamping blocks 45 are on the same horizontal line as the support cross bars 43. The clamping blocks 45 A second control hole 46 is also provided on the outer side thereof, and the second control hole 46 cooperates with the first control hole 12. A rod body is inserted into the second control hole 46 and the first control hole 12, and a telescopic end 44 is fixed on the inner side of the clamping block 45. The telescopic end 44 has a spring inside and can be telescopically arranged. The end of the telescopic end 44 is against the driving shaft 41. In the process of adjusting the clamping block 45 in the up and down directions, the space of the inverted triangle mouth 11 is limited, so the clamping block 45 squeezes or relaxes the telescopic end 44.

[0035] A limiting plate 6 for support is sleeved on the rear side of the adjusting wheel 42 , and the rear end of the limiting plate 6 is fixed to the base plate 1 , so as to achieve the function of stabilizing the operation of the adjusting wheel 42 .

[0036] When in use, the wire is passed through the through hole 32 at one end and then passed out from the other through hole 32. The wire between the two through holes 32 is wound around two sets of transmission wheels 5 and an adjusting wheel 42. The transmission directions on both sides are different. The fastening nut 35 is loosened, and the direction of the adjusting plate 31 can be adjusted at will, and it can be moved in the arc-shaped sliding port 2, which is convenient for multi-directional adjustment. Secondly, the wire transmitted inward is squeezed onto the transmission inner wheel 38 to avoid squeezing the wire. At the same time, the control circle 36 can be rotated according to the direction of the wire moving from the outside to the inside. The direction of the transmission inner wheel 38 can be changed, so that no matter in which direction it moves into the control circle 36, it can be transmitted to avoid jamming.

[0037] Secondly, during the transmission of the silk thread, the rod body in the second control hole 46 on the clamping block 45 is taken out, and the clamping block 45 can be slid along the inverted triangle mouth 11. During the movement from bottom to top, under the elastic force of the telescopic end 44, the two groups of clamping blocks 45 are relatively separated, so that the squeezing force of the telescopic ends 44 on the drive shaft 41 on both sides is reduced, so that the drive shaft 41 can rotate more smoothly. On the contrary, the clamping block 45 moves downward, which increases the squeezing force of the telescopic end 44 on the drive shaft 41 and the resistance, thereby controlling the resistance to silk thread transmission and controlling the silk thread tension.
