Detailed Description

The following provides a specific embodiment of a reel of a reeling machine according to the present invention with reference to the drawings, which are only illustrative and not limiting for the claims of the present invention, and the invention is not described as applicable to the prior art.

An embodiment of a reel for a reeling machine according to the invention (as shown in figures 1-3):

a yarn reel of a reeling machine is used for the reeling machine, a yarn reel shaft 10 of the reeling machine is a hollow shaft, a yarn reel suction port 17 (shown in figure 2) and an air nozzle 151 which are arranged on the shaft are sealed, the yarn reel suction port 17 is a hole which is formed in the outer side of the yarn reel shaft 10 and is used for being connected with a negative pressure air suction device, for example, a connector 19 (shown in figure 3) which is made of rubber with the shape similar to that of the yarn reel suction port 17 (made of other materials is not eliminated) is used for introducing negative pressure air suction into the yarn reel shaft 10, the connector can be contacted with the yarn reel shaft 10 when negative pressure air suction is needed, and the rubber connector is driven by a connector driving air cylinder 191 to leave the yarn reel shaft 10 when the yarn reel shaft rotates and twists yarns. In addition, one end opening of the yarn frame shaft 10 can be connected to the negative pressure air suction device, a method similar to the yarn frame suction port 17 can be adopted during connection, the connecting piece is only contacted with the end face of the opening of the yarn frame shaft when negative pressure air suction is needed, and a sealing piece (such as a graphite sealing piece) can also be adopted to be pressed and always contacted.

The automatic bobbin winder comprises a bobbin frame, a movable supporting rod 121, a herringbone rod structure and a herringbone rod structure, wherein 6 bobbin winding rods are arranged on the bobbin frame, 4 fixed bobbin winding rods 14 are arranged on a bobbin frame shaft 10 through fixed supporting rods 11, two movable bobbin winding rods 13 are arranged on the bobbin frame shaft through movable supporting rods 12, the herringbone rod structure is driven by the movable bobbin winding rods 13 to move up and down (as shown in figure 3), the herringbone rod structure is driven by the movable supporting rod 121 to move up and down, so that the circumference of the bobbin frame is adjusted, the herringbone rod structure belongs to a common structure for lifting in the mechanical field, and the herringbone arm for clamping bobbin yarns in the collective doffing device of the ring spinning frame is the herringbone rod structure. All the yarn winding rods are movable yarn winding rods, and the herringbone rod structure is adopted for driving the lifting or the pull rod mechanism and other structures are adopted for driving the lifting.

The yarn frame of the reeling machine is characterized by comprising a yarn sucking component and a yarn holding component which are arranged on the yarn frame,

the holding suction pipe 15 is used as a threading yarn suction part and is arranged on the yarn frame shaft 10 through the holding suction pipe mounting seat 16 and the fixed support rod 11, the holding suction pipe 15 is a silicone tube (tubular parts made of other materials are not excluded), one end (upper left in the figure 1) is opened, the other end (lower right in the figure 1) is connected to the inside of the yarn frame shaft 10 through an air nozzle 151, and negative pressure is sucked and connected to the holding suction pipe 15 through a hole of the yarn frame shaft 10 when yarn suction is needed. Although the holding suction pipe 15 can also be installed on the yarn frame shaft 10 through the movable support rod 12, in this case, the holding suction pipe 15 can move along with the movable yarn winding rod 13, when the twisting is needed or the diameter of the twisted yarn needs to be adjusted, the position of the holding suction pipe 15 can be changed, the yarn is not beneficial to automatically feeding the yarn into the inlet of the holding suction pipe 15 when the automatic threading is not facilitated, the automatic positioning is not beneficial, therefore, the holding suction pipe 15 and the yarn frame shaft 10 are preferably kept relatively static, if all the yarn winding rods on the yarn frame are movable yarn winding rods, the holding suction pipe 15 needs to be separately fixedly installed with the yarn frame shaft 10 by a support part similar to the fixed support rod 11, and the holding suction pipe 15 cannot move along with the movable yarn winding rods in the radial direction of the yarn frame.

The holding tension ring 152 (as a yarn threading holding part) is a bending surrounding structure positioned on the holding suction pipe, the yarn can form a surrounding angle of 360 degrees after passing through the holding tension ring 152, when the yarn is pulled out from the open end of the yarn threading holding part, the holding tension ring 152 can apply tension to the yarn, when the yarn frame rotates, the holding suction pipe ensures that the yarn in the holding suction pipe 15 is not pulled out by virtue of the tension, but the yarn on the yarn guide hook is pulled out and wound on the yarn winding rod when the yarn frame rotates. If it is desired to increase the additional tension on the yarn, the number of turns of the holding tension ring 152 may be increased, or the coefficient of friction between the holding tension ring 152 and the yarn may be increased (e.g., in general, the coefficient of friction between silicone or polyurethane and the yarn is greater than the coefficient of friction between PVC or metal and the yarn), and the suction airflow in the holding suction tube 15 may be maintained while the holding suction tube 15 rotates the yarn carried therein, resulting in greater additional tension on the yarn than if the suction airflow is not maintained, and the greater the length of the yarn sucked by the holding suction tube 15 in the suction direction beyond the position of the holding tension ring 152, the greater the additional tension in the case that the holding suction tube 15 maintains the suction airflow.

A holding suction pipe 15 and a holding tension ring 152 are arranged at each spindle position of the reeling machine.

The working principle of the yarn frame of the reeling machine is as follows: the initial segment of hank yarn is placed near the opening end of the holding suction pipe 15, when the holding suction pipe 15 can suck the hank yarn, the holding suction nozzle 15 sucks the initial segment of hank yarn into the holding suction nozzle 15 through negative pressure air suction, the length of the yarn sucked by the holding suction nozzle 15 ensures that the sucked yarn can pass through the holding tension ring 152 to complete yarn threading, a yarn frame can start to rotate to wind the yarn on a yarn frame support rod, the yarn cannot be thrown out in the rotation process of the yarn frame due to the fact that the yarn passes through the holding tension ring 152, and when the yarn frame just starts to rotate, the yarn can be pulled out by a yarn guide hook instead of the yarn in the holding suction nozzle 15.

The gripping tension ring 152 is a 360-degree enclosing structure formed by directly bending a tube on the yarn moving suction pipe, and structures such as half enclosing, continuous two-circle or multi-circle enclosing and the like are not excluded. And can also be made without bending the pipe, and directly prepare a part with a semi-surrounding or surrounding structure through hole inside by using an injection molding or casting method as a raw head holding part to replace the holding tension ring 152 to be connected with the holding suction pipe 15, even directly replace the holding suction pipe 15 by a raw head holding part inlet prepared by using the injection molding or casting method.

Although the yarn feeding member in this embodiment is a tubular member, it is not excluded to use a member having a through hole of another shape as the yarn feeding member, for example, a box-like member connected to the negative pressure suction fan.

The inside of yarn frame axle 10 is used for leading to the negative pressure among the embodiment and induced drafts, if want to reduce the processing degree of difficulty of yarn frame axle, can not lead to the negative pressure with yarn frame axle 10 and induced draft, and fix a root canal alone along its length direction on the yarn frame axle and be used for connecting the negative pressure and induced draft the device and hold the straw.

The thread-up holding part in this embodiment is a part comprising a curved semi-surrounding or surrounding tubular cavity structure, but mechanical holding with a driving part is not excluded, for example, the holding suction tube 15 is made of a rubber tube, an air cylinder is arranged on the outer side of the holding suction tube 15, and a pressing bar arranged on the air cylinder rod when the air cylinder extends presses the holding suction tube 15 to hold the yarn therein. Even other holding schemes such as elastic pressing holding, driving and loosening holding by a driving part and the like are included, for example, a 'flip cover' and a 'slip cover' are added at the opening part of the yarn feeding and sucking part, or the opening end of the holding suction pipe moves to the position below the shielding part to cover the opening, so that the effect of additional tension when the yarn sucked by the yarn feeding and sucking part is pulled out can be achieved, the parts can be driven to move, and the schemes can be realized in various forms.
