Detailed Description

It is easily understood that, according to the technical solution of the present invention, a person skilled in the art can propose various alternative structural modes and implementation modes without changing the essential spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are only exemplary of the technical aspects of the present invention, and should not be considered as limiting or restricting the technical aspects of the present invention in its entirety or as limiting or restricting the technical aspects of the present invention.

The directional terms upper, lower, left, right, front, rear, front, back, top, bottom and the like that are or may be mentioned in this specification are defined relative to the configurations shown in the drawings, and are relative concepts that may be changed accordingly depending on the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and descriptive purposes only and not for purposes of indication or implication as to the relative importance of the respective components.

It will be appreciated that although the twisting mechanism of the present invention is generally used for twisting fibers, it is actually capable of twisting not only fibers, but also already formed yarns or yarns already having a twist or other yarns used for weaving, etc., so that reference to "fibers" is used herein in its broadest sense, i.e., fibers, yarns or other yarns used for weaving, etc., that are capable of being twisted by the twisting mechanism.

Referring to fig. 1, there is shown a schematic structural view of a proposed twisting mechanism 100 according to an embodiment of the present invention. The twisting mechanism 100 is used to twist, i.e., increase the twist of, the fiber 10 supplied to the take-up mechanism 200, that is, the fiber 10 unwound from the fiber drum 103. The twisting mechanism comprises a motor 101, a transmission shaft 102 connected with the motor and a fiber barrel 103 sleeved on the transmission shaft 102. The motor 101 can drive the drive shaft 102 to rotate, so that the drive shaft 102 also drives the fiber barrel 103 to rotate. The fiber 10 for unwinding is wound around the fiber drum 103, one end of the fiber 10 is wound around the take-up mechanism 200, for example, the take-up spool 203 of the take-up mechanism 200, and the fiber 10 can be wound around the take-up mechanism 200 step by the rotation of the take-up spool 203 of the take-up mechanism 200. The fibers 10 are twisted during the unwinding of the fibers 10 from the fiber reel, i.e. the unwinding of the fibers 10 from the fiber reel, by means of a rotation driven by a motor 101.

It should be understood that the twisting is realized by rotating one end of the fiber 10 and outputting the other end, and the "rotation" of the fiber 10 is realized by the rotation driven by the motor 101 during the unwinding process from the fiber drum 103, and the "output" of the fiber 10 is realized by the rotation of the take-up mechanism 200, that is, the unwinding of the fiber 10 from the fiber drum 103 is driven by the take-up mechanism 200. The output direction of the fibers 10 from the fiber drum 103 is generally a direction toward the end of the drive shaft 102 not connected to the motor 101 (approximately the axial direction of the drive shaft 102), which forms an angle, for example, 90 ° with the direction of rotation of the motor 101. That is, in this case, the motor 101 applies a force component to the fiber 10 at an angle to the output direction by rotation, so that the fiber 10 itself is twisted by the force component with the output direction as a central axis, thereby twisting the fiber 10.

It should be appreciated that the added twist of the fiber 10 is equal to the ratio of the number of revolutions of the fiber drum 103 to the take-up length, i.e., the added twist of the fiber 10 is dependent on the ratio of the rotational speed of the fiber drum 103 to the take-up speed, the number of revolutions of the fiber drum 103 per unit time, i.e., the rotational speed, is determined by the rotational speed of the drive shaft 102, and the take-up length per unit time, i.e., the take-up speed, is approximately equal to the product of the rotational speed of the take-up reel 203 and the circumference of the take-up reel 203. It follows that the ratio of the rotational speed of the drive shaft 102 to the rotational speed of the take-up spool 203 of the take-up mechanism 200 determines the added twist of the fiber 10. The larger the ratio of the two, the larger the degree of twist per unit length of the unwound fiber 10 driven by the drive shaft 102 is demonstrated, so that the increased twist thereof is larger, and the smaller the ratio of the two, the smaller the degree of twist per unit length of the unwound fiber 10 driven by the drive shaft 102 is demonstrated, so that the increased twist thereof is smaller. Therefore, the numerical value of the twist number required to be increased can be adjusted by adjusting the ratio of the rotating speed of the transmission shaft 102 to the rotating speed of the take-up reel 203 of the take-up mechanism 200, or in other words, by adjusting the ratio of the rotating speed of the motor 101 to the rotating speed of the take-up motor 201 of the take-up mechanism 200, so that the twist number of the fiber 10 can be quantitatively controlled. In one embodiment of the present invention, the motor speed is 2000 n/min, and the take-up speed is 10 m/min, so that the wound fiber has a twist of 200 n/m.

It should be understood that in addition to the twist increase for the non-twisted fibers 10 or yarns, the twisting mechanism may also, in certain circumstances, decrease the twist of yarns already having a greater twist. When it is necessary to increase the twist of the yarn, the direction of the increased twist needs to be the same as the original twist direction of the yarn, and when it is necessary to decrease the twist of the yarn, the direction of the increased twist needs to be opposite to the original twist direction of the yarn.

In one embodiment of the present invention, the motor 101 and the transmission shaft 102 are connected to each other through a transmission mechanism 104, the transmission mechanism 104 can be an acceleration, deceleration or synchronous transmission mechanism, for example, the transmission mechanism 104 is a gear transmission mechanism or a belt transmission mechanism or a chain transmission mechanism, and is used for adjusting the rotation speed relationship between the motor 101 and the transmission shaft 102 when different twists need to be applied to the fiber 10, so as to increase the adjustment range of the rotation speed of the transmission shaft 102. The gear mechanism 104 can also be designed as a multi-gear mechanism, so that the rotational speed of the drive shaft 102 can be adjusted without changing the rotational speed of the electric motor 101.

In one embodiment of the present invention, a tension device 105 is connected to one end of the transmission shaft 102 away from the motor 101, the tension device 105 can increase the tension of the fiber passing through the tension device 105, and the fiber 10 is conveyed from the fiber bobbin 103 to the take-up mechanism 200 through the tension device 105. Referring to fig. 2, there is shown a schematic structural view of a tensioner of a twisting mechanism according to an embodiment of the present invention. In one embodiment of the present invention, the tensioner 105 has an hourglass or gourd-shaped main body 1051, i.e., a structure with gradually decreasing diameters from both ends to a middle portion thereof, thereby forming a recess in the middle portion of the tensioner 105, and a snap ring 1052 surrounding the tensioner 105 is fitted in the recess, and the diameter of the snap ring 1052 is slightly larger than the minimum diameter of the hourglass-shaped main body 1051 and much smaller than the maximum diameter of the main body 1051. The fiber 10 passes through the tensioner 105 in a manner that passes through the snap ring 1052 such that as the fiber 10 passes through the tensioner 105, its path is altered, the fiber 10 passing through the snap ring 1052 is pulled closer to the central axis of the tensioner 105 than the snap ring 1052, thereby achieving tension enhancement to the fiber 10. In embodiments not shown, the tensioner may also be configured as other types of mechanisms capable of enhancing the tension of the fiber 10, such as a tension roller or the like.

In one embodiment of the present invention, a locking mechanism 106 and a control mechanism 107 (both are only schematically shown in fig. 1) are installed on the motor, the locking mechanism 106 can lock and release the transmission shaft 102, and the control mechanism 107 controls the locking mechanism 106 to immediately lock the transmission shaft 102 when the motor 101 stops working, so that the transmission shaft 102 immediately stops rotating. This prevents the transmission shaft 102 from continuing to rotate due to inertia when the motor 101 stops operating and unwinding the fiber 10, and the fiber 10 cannot be twisted due to the non-operation of the motor 101. The locking mechanism 106 is configured, for example, as a clamp locking mechanism (not specifically shown in the drawings), which has a clamp-like clamping portion, and can control opening and closing of the clamping portion by a control mechanism 107. When the motor 101 stops working, the control mechanism 107 immediately controls the clamping part to clamp the transmission shaft 102 to stop rotating the transmission shaft 102; when the motor 101 starts operating, the control mechanism 107 controls the clamping part to release the transmission shaft 102. The locking mechanism 106 can also be configured, for example, as a latching mechanism with a latching projection (not shown in detail in the figures), and a latching recess which can be brought into form-fitting engagement with the latching projection is configured on the drive shaft 102. The control mechanism 107 can control the movement of the card lock mechanism in the radial direction of the drive shaft 102. When the motor 101 stops working, the control mechanism 107 controls the locking mechanism to enable the locking protrusion part to be clamped into the locking concave part of the transmission shaft 102 along the radial direction of the transmission shaft 102, so that the transmission shaft 102 is locked and cannot rotate; when the motor 101 starts operating, the control means 107 controls the latch projection to move out of the latch recess in the radial direction of the drive shaft 102, so that the drive shaft 102 can rotate freely. In a further embodiment of the invention, the locking mechanism and the control mechanism can of course also be mounted directly on the transmission shaft.

On the other hand, the present invention further provides a winding machine, and referring to fig. 3, it shows a schematic structural diagram of a winding machine according to an embodiment of the present invention. The winding machine comprises the twisting mechanism 100 and the winding mechanism 200, and the winding mechanism 200 comprises a winding motor 201, a rotating shaft 202 connected with the winding motor, and a winding drum 203 sleeved on the rotating shaft 202, which are schematically shown in a block form in fig. 3. The take-up motor 201 rotates the take-up reel 203 through the rotating shaft 202 so that the fiber 10 from the twisting mechanism 100 can be wound onto the take-up reel 203 step by step. Before winding, the fiber on the fiber drum 103 of the twisting mechanism 100 is partially wound on the take-up reel 203 of the take-up mechanism 200, so that the fiber 10 can be gradually wound thereon when the take-up reel 203 rotates.

In one embodiment of another aspect of the present invention, the winding machine further comprises a tension enhancing mechanism 300 disposed between the twisting mechanism 100 and the take-up mechanism 200 for enhancing the tension of the fiber. The tension intensifying apparatus 300 is configured, for example, as a plurality of tension rollers 301, and the plurality of tension rollers 301 are not arranged on the same straight line. That is, the plurality of tension rollers 301 form a curved path when the fiber 10 is conveyed, so that tension enhancement of the fiber 10 can be achieved to various degrees by controlling the distance between the plurality of tension rollers 301, the relative rotation speed, and the frictional force between the fiber 10 and the tension rollers 301.

It should be understood that all of the above preferred embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above, which may occur to those skilled in the art upon reading the teachings of the present invention, are intended to be within the scope of the appended claims.
