Detailed Description

For a better understanding of the technical content of the present utility model, specific examples are set forth below, along with the accompanying drawings.

The utility model discloses a rewinding device with a pressing mechanism, which aims to solve the problems that a winding roller in a rewinding vehicle in the prior art is easily vibrated due to equipment vibration in the yarn winding and rewinding process, so that after yarns are wound into a spool, the quality of a finished product of the spool is poor, and the spool is different in meter length and broken yarns due to uneven yarn tension when the spool is applied to weaving and spinning. As shown in figures 1-3, the utility model can offset the influence of the vibration of the equipment on the winding drum by applying downward pressure to the winding roller and by virtue of the downward pressure brought by the pressure applying mechanism, so that the shaking of the winding drum during operation is greatly balanced, the molding quality of the wound yarn drum is good, and the phenomenon of rice length difference and yarn breakage caused by uneven tension is avoided when the winding drum is applied to weaving and spinning.

The rewinding device with the pressing mechanism of the embodiment shown in connection with fig. 1-4 comprises a yarn guiding mechanism 10, a yarn winding mechanism 20 and a pressing mechanism 30.

The yarn guiding mechanism 10 and the yarn winding mechanism 20 are both mounted on the rewinding frame 1, and the yarn guiding mechanism 10 is used for winding and shaping the yarn.

The yarn winding mechanism 20 is used for receiving the yarn wound on the yarn guiding mechanism 10 and winding the yarn to form a new bobbin.

The pressing mechanism 30 is installed on the yarn winding mechanism 20 to apply pressure to the yarn winding mechanism 20 to keep the yarn guiding mechanism 10 always in contact with the yarn winding mechanism 20 and to balance the shake of the yarn winding mechanism 20 when the apparatus is operated.

Further, the yarn guiding mechanism 10 includes a grooved drum 11 for uniform wiring and a driving motor 12 for driving the grooved drum 11 to rotate. As shown in fig. 2, the driving motor 12 drives the grooved drum 11 to rotate through the driving belt 13, and optionally, an output shaft of the driving motor 12 is connected with a first belt pulley in a transmission manner, a second belt pulley is fixed at the end part of the grooved drum 11, and the driving belt 13 is sleeved outside the first belt pulley and the second belt pulley.

Specifically, the grooved drum 11 is one of the important winding components on the rewinding machine, and since the tension and winding density of the yarn 100 during winding are the main basis for measuring the forming quality of the yarn bobbin, the grooved drum 11 is provided with a spiral groove, and the curve shape of the spiral groove determines the motion rule and the distribution condition of the yarn coil on the bobbin during yarn winding, so that the forming quality of the bobbin is directly affected.

Further, the yarn winding mechanism 20 comprises a winding roller 23 which is attached to the grooved drum 11 and rotates, and an inclined support plate 22 for supporting the winding roller 23, wherein the winding roller 23 is rotatably arranged at the top of the inclined support plate 22.

Specifically, the winding drum is sleeved on the winding roller 23 and is used for receiving the yarn on the grooved drum 11 and winding the yarn 100 to form a new winding drum, the winding drum is detachably connected with the winding roller 23, and after the winding drum on one winding drum is wound and formed, the yarn can be continuously wound by replacing the new winding drum.

Optionally, the inclined support plate 22 is installed on the frame 1 of the rewinding machine at an angle, and is mainly used for supporting the wind-up roller 23 to keep a proper height against the grooved drum 11.

Because the winding drum only depends on mutual interference with the groove drum 11 to generate mutual rotation so as to realize winding of the yarns, the winding drum needs to keep mutual interference with the groove drum 11 in the winding process of the yarns.

In an alternative embodiment, the pressure applying mechanism 30 is configured to apply pressure to the wind-up roll 23 in a direction toward the grooved drum 11 such that the wind-up roll 23 is maintained in rotation in a conforming relationship with the surface of the grooved drum 11.

In the process of continuously winding the yarn, the diameter of the yarn winding drum is gradually increased, and the distance between the winding roller 23 and the groove drum 11 needs to be adjusted, so that the yarn winding space is provided.

In an alternative embodiment, two symmetrically distributed side support plates 21 are mounted on the inverted tub vehicle frame 1, and the bottom ends of the inclined support plates 22 are disposed between the two side support plates 21 and are rotatably connected with the side support plates 21.

Thus, when the yarn winding thickness of the winding drum on the winding roller 23 is increased, the inclined support plate 22 can automatically adjust the inclination angle according to the winding thickness of the yarn 100 on the winding roller 23, so that the inclined support plate can drive the winding roller 23 to move, the interval between the winding roller 23 and the groove drum 11 is gradually increased while the winding roller 23 is kept in contact with the groove drum 11, and the winding space of the yarn 100 is provided.

Because the inclined support plate 22 is rotationally connected with the side support plate 21 for realizing angle adjustment, the inclined support plate 22 is easily vibrated due to the influence of equipment vibration in the yarn winding and rolling process, and the winding roller 23 is arranged at the top end of the inclined support plate 22, so that the vibration and angle change of the inclined support plate 22 can influence the winding roller 23, the winding roller 23 can shake, the winding quality of yarns is affected, for example, local yarns are excessively loosened or excessively tightened, the winding density of yarn drums is uneven, the phenomenon of uneven meter length difference and yarn breakage is caused when the yarn drums are applied to weaving and spinning due to uneven yarn tension, and the stability of the winding roller 23 in the yarn 100 winding process and the quality of yarn drums after winding are ensured.

As shown in fig. 1 and 2, the pressing mechanism 30 is attached to the inclined support plate 22, and applies pressure to the inclined support plate 22 in the direction of the grooved drum 11, thereby causing the wind-up roller 23 to always contact the surface of the grooved drum 11.

Specifically, the pressing mechanism 30 is mainly used for applying pressure to the inclined support plate 22, so as to offset the influence of vibration of equipment on the winding drum, greatly balance the shaking of the winding drum during operation, enable the winding drum to be always stably kept in contact with the grooved drum 11 in the winding process of yarns, and enable the wound yarn drum to have good forming quality, so that the warp breaking influence on the cloth machine caused by uneven yarn forming poor tension due to shaking of the winding drum is solved.

In a preferred embodiment, the pressing mechanism 30 comprises at least one traction rope 31 or at least one balancing weight 32, acting on the inclined support 22, to bring the wind-up roller 23 into pressure engagement with the grooved drum 11 at all times.

As shown in fig. 2 and 3, in a preferred embodiment, the pressing mechanism 30 includes at least one traction rope 31 and at least one balancing weight 32 disposed at the tail end of the traction rope 31, and the balancing weight 32 is suspended below the inclined support plate 22 by the traction rope 31, and applies a force against the inclined support plate 22 in the direction of the grooved drum 11.

Specifically, the hauling rope 31 adopts wire rope, and first end is fixed on the inclined support plate 22, and the balancing weight 32 is installed to the other end, and balancing weight 32 adopts the solid structure that has the metal material of certain weight, and balancing weight 32 hangs in the below of inclined support plate 22 through the wire rope, in the winding process of yarn 100, remains a effort of pulling down all the time to inclined support plate 22, makes the wind-up roll 23 on inclined support plate 22 top remain all the time and contradict each other with grooved drum 11 and rotate each other to realize the stable rolling of yarn.

Alternatively, the pressing force of the pressing mechanism 30 to the inclined stay 22 is always kept downward. As shown in fig. 1, 2 and 3, a positioning support plate 34 and a pulley 35 rotatably installed at the top of the positioning support plate 34 are further provided under the inclined support plate 22. The pulley 35 is mainly configured to change the direction of the acting force of the counterweight 32.

Specifically, the first end of the traction rope 31 is fixed on the inclined support plate 22, the second end extends and is erected on the pulley 35, and the acting force of the balancing weight 32 on the inclined support plate 22 is always kept downward through the pulley 35.

In an alternative embodiment, the traction ropes 31 are mounted on pulleys 35 for stability. As shown in the figure, a wire groove is formed on the peripheral side of the pulley 35, and the cross-sectional area of the wire groove is larger than that of the traction rope 31, so that the traction rope 31 can slide in the wire groove and the traction rope 31 is limited from sliding out of the pulley 35.

Further, in order to make the fixation of the traction rope 31 on the inclined strut 22 more stable. As shown in fig. 2, 3 and 4, the inclined support plate 22 includes a lower support plate 221 and an upper support plate 222 located above the lower support plate 221, and a rope hole 201 through which the traction rope 31 can pass is formed in the lower support plate 221.

Specifically, the upper support plate 222 is used for installing the wind-up roller 23, and the lower support plate 221 is fixed between the side support plates 21 and provided with a rope hole 201 through which the traction rope 31 can be threaded. When the traction rope 31 is fixed, the first end of the traction rope 31 penetrates through the rope hole 201, and a knot with a diameter larger than that of the rope hole 201 is tied outside the rope hole 201, so that the traction rope 31 cannot fall out of the rope hole 201.

In an alternative embodiment, the first end of the traction rope 31 is fitted with a wire clamp 33 having a circumscribed circle diameter larger than the rope hole 201 in order that the first end of the traction rope 31 does not come out of the rope hole 201. Specifically, the wire clamp 33 may be a commercially available product such as a wire clamp, a clip U-shaped clamp, or the like.

Further, a supporting plate 311 for limiting the weight 32 falling down from the traction rope 31 is disposed at the second end of the traction rope 31, and the supporting plate 311 is mainly disposed to limit the weight 32 so as not to fall out of the traction rope 31.

Specifically, the supporting plate 311 may be made of metal alloy, and is prefabricated into a plate structure with a hole in the center, preferably with a circular cross section, and when the traction rope is installed, the second end of the traction rope 31 passes through the center hole of the supporting plate 311 and is limited by the wire clip 33 or the knot, so that the supporting plate 311 cannot slip out of the traction rope 31. And a central shaft hole with an inner diameter larger than that of the traction rope 31 is formed at the inner center position of the balancing weight 32.

Thus, when installing the weight 32, the weight 32 can be first inserted onto the traction rope 31 according to the pressure applied to the inclined support plate 22, and then the support plate 311 is installed to fix the weight 32 onto the traction rope 31.

As shown in fig. 4, the supporting plate 311 may be fixed on the traction rope 31, and when the counterweight 32 is mounted, the supporting plate 311 is folded to be parallel to the traction rope 31, and passes through the central shaft hole of the counterweight 32 together with the traction rope 31, and finally the supporting plate 311 is folded to be perpendicular to the traction rope 31, so as to limit the counterweight 32.

Additional alternative embodiments of the pressing mechanism are shown in exemplary connection with fig. 5 and 6.

As shown in fig. 5, the pressing mechanism is implemented using a traction rope 31. The hauling rope 31 adopts elastic rope, and optionally, the first end of the elastic rope is fixed on the inclined support plate 22, the second end of the elastic rope is fixed on the rewinding vehicle frame 1, and the elastic rope has traction force, and can apply the pulling force to the inclined support plate 22, which is propped against the direction of the grooved drum 11, so that the wind-up roll 23 is always kept to be attached to the grooved drum 11.

As shown in fig. 6, the pressing mechanism is implemented using a weight 32. The balancing weight 32 is made of metal and is prefabricated into a solid structure with a certain weight, and optionally, the balancing weight 32 can be provided with one or more than one and is fixed at any position on the inclined support plate 22, so that pressure which is propped against the inclined support plate 22 in the direction of the groove drum 11 can be applied to the inclined support plate 22, and the winding roller 23 is always attached to the surface of the groove drum 11.

It should be appreciated that, through the arrangement of the bearing plate 311, if the weight block 32 is found to be insufficient to stabilize the wind-up roll 23 during the subsequent working process of the apparatus, the weight or number of the weight block 32 can be appropriately increased as required, so that the pressing force meets the stable working of the wind-up roll 23, and the bearing plate 311 makes the disassembly, assembly and replacement of the weight block 32 more flexible.

It should be understood that if the yarn drum is poor in molding quality, normal use during weaving and spinning cannot be satisfied, the yarn drum needs to be rewound by means of a rewinding machine, and the warp breaking needs to be stopped for continuous connection and restarting equipment, so that from the economic benefit, the warp breaking rate during spinning and weaving is reduced by improving the molding quality of the yarn drum, and the profit of enterprises can be greatly improved by reducing miswork caused by reworking and poor quality of finished products.

While the utility model has been described with reference to preferred embodiments, it is not intended to be limiting. Those skilled in the art will appreciate that various modifications and adaptations can be made without departing from the spirit and scope of the present utility model. Accordingly, the scope of the utility model is defined by the appended claims.
