Description

Technical Field

[0001] The utility model relates to the field of rubber reinforcement manufacturing, in particular to a tension regulating device for taking up or paying out multiple wires in the production of metal wire products, and a steel cord twisting mechanism and a steel wire production mechanism with the tension regulating device. Background Art

[0002] The production of rubber reinforcements such as tires, hoses, and conveyor belts requires large quantities of steel cord. Steel cord is a rope made by twisting two or more steel wires. Typically, the steel cord production process includes payout, twisting, and reeling. This process requires a series of transmission mechanisms, such as guide pulleys, to guide and redirect the wire or cord. Steel cord payout involves unwinding the wire from a spool. Existing spools can wind a single wire, which can be up to 100,000 meters long. When producing steel cords containing multiple wires, a large number of wires need to be paid out simultaneously, requiring a large space to accommodate multiple spools. To save space, an existing improvement involves winding two, three, or even more steel wires onto a single spool, reducing the number of payout spools and conserving space for their placement.

[0003] However, this approach introduces new challenges. For example, when two, three, or more steel wires are wound around a spool, they are paid out and then transferred to a twisting device for twisting into a rope. Ideally, the payout length and tension of these wires must be maintained at the same predetermined level during this process. However, in practice, the payout length or tension of some wires may not be consistent with the predetermined level, potentially leading to wire breakage and rope defects.

[0004] Therefore, it is necessary to provide a tension adjusting device, a steel cord twisting mechanism and a steel wire production mechanism having the same, so as to at least partially solve the above problems. Utility Model Content

[0042] Now, with reference to the accompanying drawings, the specific embodiments of the present invention will be described in detail. What is described here is only a preferred embodiment of the present invention. Those skilled in the art can conceive of other ways to implement the present invention based on the preferred embodiment, and the other ways also fall within the scope of the present invention.

[0043] The present invention provides a tension-adjusting device for winding or unwinding multiple wires in the production of metal wire products, and a steel cord twisting mechanism and a steel wire production mechanism equipped with the tension-adjusting device. The tension-adjusting device is suitable for adjusting tension during multi-wire winding and multiple unwinding, for example, for multi-wire winding during metal wire product production, such as the multiple unwinding of steel cords at the beginning of steel cord production and the winding of multiple steel cords after rope formation. Metal wire products include steel cords for rubber reinforcement, steel ropes for lifting, and steel wire, or wires made of other materials, such as copper wire, tungsten wire, or a metal rope mixed with metal wire and synthetic wire. The tension-adjusting device provided by the present invention can be used for winding and unwinding any type of wire, and the wire mentioned in the present invention can be either wire or rope.

[0044] Figure 1-3 Two embodiments of the tension adjustment device according to the present embodiment are shown. First of all, it should be noted that the direction and position terms of the present invention should be understood as relative directions and relative positions, rather than absolute directions and absolute positions. The direction and position terms of the present invention can be combined with the following: Figure 1-3 For example, the axial direction of the guide wheel mentioned in the present invention can be understood as Figure 1-Figure 2 The axis X shown in the figure, the radial direction of the guide wheel can be understood as Figure 2 The direction R shown in .

[0045] Figure 1-Figure 2 The figure shows a tension adjustment device 100 according to a preferred embodiment of the present invention. The tension adjustment device 100 comprises a base 120 and three sets of tension adjustment members 130. The base 120 comprises a seat 122 for fixing the tension adjustment device 100 on a production device and a column 121 extending upward from the seat 122.

[0046] by Figure 1Taking the topmost set of tension adjusters 130 shown in the figure as an example, each set of tension adjusters 130 includes a guide wheel 131 for guiding the thread through the thread and a connector 132 for connecting the guide wheel 131 to the base 120. The guide wheel 131 and the connector 132 are mounted on the column 121 of the base 120. Specifically, the connector 132 includes a guide wheel bracket 1322 and at least one spring 1321. The guide wheel bracket 1322 includes a connecting shaft 1322b and a support shaft 1322a. The guide wheel 131 is supported on the guide wheel bracket 1322 by passing through the connecting shaft 1322b. The guide wheel bracket 1322 is supported and positioned on the base 120 by the support shaft 1322a. The spring 1321 passes through the support shaft 1322a of the guide wheel bracket 1322 and is located between the base 120 and the guide wheel 131. The support shaft 1322a extends radially along the guide wheel 131, so that the spring 1321 mounted thereon also extends radially along the guide wheel 131. The spring 1321 can be stretched or compressed radially along the guide wheel 131. A guide wheel groove 1311 is provided on the circumferential outer surface of the guide wheel 131, into which the wire is inserted, preventing it from falling off the guide wheel 131.

[0047] The guide wheel 131 is elastically mounted on the column 121 of the base 120 via a connector 132 , so that when the pressure on the guide wheel 131 changes, the guide wheel 131 can elastically slide relative to the base 120 in the radial direction. Figure 2 FIG2 shows a top view of a guide wheel 131 under normal use, schematically illustrating the mutual force relationship between the wire 300 and the guide wheel 131. The guide wheel 131 receives the maximum radial force exerted by the corresponding wire 300 at the maximum force point P on the outer circumference of the guide wheel 131. Preferably, the spring 1321 and the maximum force point P are located in the same radial direction of the guide wheel 131, and in opposite directions of the same radial direction.

[0048] For example, the maximum force point P is on one side of the guide wheel 131 in the R2 direction, the spring 1321 is set on one side of the guide wheel 131 in the R1 direction, the guide wheel 131 and the maximum force point P are in opposite directions of the same radial direction relative to the axis of the guide wheel 131, and the radial position of the guide wheel 131 is adjusted by the spring 1321 to adjust the tension of the wire 300.

[0049] During use, three wires 300 are simultaneously paid out from the same spool. As they pass through guide wheel 131, wires 300 exert pressure on guide wheel 131, which in turn compresses spring 1321. Under normal conditions, the three wires 300 have the same payout length and a consistent, pre-set tension level. When the wire 300 is stretched to the limit of 0, the guide wheel 131 is pulled back to rotate with the help of the spring 1321, and the guide wheel 131 is pulled back to rotate with the help of the spring 1321. When the wire 300 is stretched to the limit of 0, the guide wheel 131 is pulled back to rotate with the help of the spring 1321, and the guide wheel 131 is pulled back to rotate with the help of the spring 1321. When the wire 300 is stretched to the limit of 0, the guide wheel 131 is pulled back to rotate with the help of the spring 1321, and the guide wheel 131 is pulled back to rotate with the help of the spring 1321. Preferably, during use, spring 1321 is always in a compressed state. When guide wheel 131 is at its furthest position in the R2 direction, spring 1321 is compressed to the minimum; when guide wheel 131 is at its furthest position in the R1 direction, spring 1321 is compressed to the maximum. This is the working principle of the present device for adjusting the tension of the silk thread. In particular, when two or more silk threads are simultaneously released from a spool, the present device can simultaneously adjust the tension of two or more silk threads by configuring multiple tension adjustment members on a tension adjustment device. Compared to the existing method of adjusting the tension of a silk thread by configuring a tension adjustment member on a single tension adjustment device, the present device reduces the number of tension adjustment devices and saves the space used for the tension adjustment devices.

[0050] The axes X of the guide wheels 131 of the three groups of tension adjusting members 130 of this embodiment are parallel to each other. The three groups of tension adjusting members 130 are arranged axially and are preferably located on the same side of the column 121, and are located on the same side relative to the column 121 as the seat 122. The radial sliding motions of the guide wheels 131 of each group of tension adjusting members 130 are independent of each other, and each guide wheel 131 is used to adjust the tension of a corresponding silk thread. Therefore, the axes of the guide wheels 131 of the three groups of tension adjusting members 130 are only parallel to each other and can be collinear or non-collinear ( Figure 1 An example is shown in FIG. 1 , in which the three guide wheels 131 are all in an initial position, where the axes X of the three guide wheels 131 are collinear).

[0051] Preferably, each guide wheel 131 is configured to rotate about its axis X, and the connecting shaft 1322b constitutes a pivot axis for the rotation of the corresponding guide wheel 131. Such an arrangement can reduce the friction between the guide wheel 131 and the wire during the wire conduction process.

[0052] In other embodiments not shown, the tension adjustment device may have other configurations. For example, the base may have other configurations, such as not including a seat, with the bottom of the column directly fixed to the production equipment by bolts or other means. The connector may also have other configurations to elastically mount the guide wheel on the base. Each set of tension adjustment members may be located on different sides of the column. The spring may also be positioned on the same side of the maximum force point, with the spring adjusting the radial position of the guide wheel through tension rather than thrust. More than one spring may also be provided, such as one spring providing thrust to the guide wheel while another provides tension. The number of tension adjustment members may be adjusted based on the number of threads being paid out from the same spool. For example, if two threads are being paid out from the spool, the tension adjustment device may be equipped with two tension adjustment members, or if three threads are being paid out from the spool, the tension adjustment device may be equipped with three tension adjustment members.

[0053] Figure 3 Shown is a tension adjustment device 200 according to another preferred embodiment of the present invention. Figure 1-2 For the sake of simplicity, the same or similar structures of the embodiments shown will not be described in detail.

[0054] In this embodiment, the tension adjustment device 200 includes a base 220 and three groups of tension adjustment members 230 mounted on the base 220. The base 220 is formed as a whole into a roughly columnar structure with X1 as the axis. The columnar structure includes a bottom column located at the bottom and a mounting column 221 located above the bottom column. The radial dimension of the bottom column is larger than the radial dimension of the mounting column 221. The mounting column 221 is used to mount each group of tension adjustment members 230. Each group of tension adjustment members 230 includes a guide wheel 231 for guiding the wire through the line and a connecting member (not shown) for connecting the guide wheel 231 and the base 220. The circumferential side surface of the guide wheel 231 is provided with a guide wheel groove 2311 for engaging the corresponding wire.

[0055] The connecting member includes at least one spring and a guide wheel positioning component (not shown). A through-hole extending axially along the guide wheel 231 is provided at the center of each guide wheel 231 to accommodate a mounting post and a spring. The mounting post 221 extends through the through-holes of all guide wheels 231. The guide wheels 231 are positioned on the mounting post 221 via the guide wheel positioning component. The spring is connected between the mounting post 221 and the guide wheels 231. The extension direction X1 of the mounting post 221 is parallel to the axial direction of each guide wheel 231, and the extension direction of the spring is in the radial direction of each guide wheel 231. The radial inner side of the spring is fixed relative to the mounting post 221, for example, and the radial outer side of the spring is fixed relative to the inner sidewall of the through-hole of the guide wheel 231.

[0056] During use of the tension adjustment device 200, the spring is preferably always in a compressed state. Three wires are simultaneously released from the same I-shaped pulley. As they pass through guide wheel 231, the wires exert pressure on guide wheel 231, which in turn compresses the spring, compressing it. Under normal conditions, the three wires have the same payout length and a predetermined, consistent tension level. When the instantaneous length of the wires engaged with guide wheel 231 increases and the tension decreases, the pressure exerted on guide wheel 231 by the wires decreases. The compressive force exerted on the spring by guide wheel 231 decreases, pushing guide wheel 231 radially toward the wires until it compresses the wires again, increasing the tension until it returns to a normal level. When the instantaneous length of the wires engaged with guide wheel 231 decreases and the tension increases, the pressure exerted on guide wheel 231 by the wires increases, causing guide wheel 231 to shift in the opposite direction, further compressing the spring, reducing the stretch of the wires and the tension until it returns to a normal level. Such a configuration enables each wire to be adjusted to a preset tension level. The radial sliding of each guide wheel 231 is independent of each other, so that the tension adjustment device can adjust each wire independently.

[0057] Preferably, each guide wheel 231 includes a core shaft portion, a bearing, and a guide wheel housing (not shown) arranged circumferentially from the inside out, wherein a through hole is provided in the core shaft portion, the guide wheel housing is configured to directly contact the wire, and the guide wheel housing is rotatable relative to the core shaft portion via the bearing. This arrangement enables each guide wheel 231 to rotate about its axis, thereby reducing friction between the guide wheel 231 and the wire during wire transmission.

[0058] The tension adjusting device 200 further includes a protective cover 240, which is disposed on the outermost (e.g., topmost) guide wheel 231. The protective cover 240 is used to prevent dust or debris from entering the through hole and to prevent heavy objects from falling and damaging the tension adjusting device 200.

[0059] The utility model also provides a steel cord twisting mechanism, which includes a tension regulating device, a pay-off device located upstream of the tension regulating device, and a twisting and rope-forming device and a take-up device located downstream of the tension regulating device. The pay-off device includes at least one pay-off spool, and each pay-off spool can pay out at least two steel wires, such as two, three or even more steel wires. The tension regulating device of the steel cord twisting mechanism can be Figure 1 or Figure 3 The tension adjustment device shown in the utility model Figure 1 or Figure 3 The description of the tension adjustment device shown should also be considered as a description of a specific embodiment of this steel cord twisting mechanism. When the steel cord twisting mechanism is in operation, at least two wires are paid out from the pay-off spool, transmitted through the tension adjustment device to the twisting and rope-forming device, and finally taken up by the take-up device.

[0060] The utility model also provides a steel cord twisting mechanism, which includes Figure 1 or Figure 3 The tension regulating device shown, the pay-off device and the twisting rope device located upstream of the tension regulating device, and the take-up device located downstream of the tension regulating device, the take-up device includes at least one take-up spool, each take-up spool can be wound around at least two steel cords. Figure 1 or Figure 3 The description of the tension adjustment device shown should also be considered as a description of a specific embodiment of this steel cord twisting mechanism. When the steel cord twisting mechanism is in operation, at least two steel cords produced by the twisting rope device are transmitted through the tension adjustment device and finally taken up on the same spool.

[0061] The utility model also provides a steel wire production mechanism, which includes a tension adjustment device, a steel wire drawing device located upstream of the tension adjustment device, and a wire take-up device located downstream of the tension adjustment device. The wire take-up device includes at least one wire take-up spool, and each wire take-up spool can be wound around at least two metal wires. The tension adjustment device of the steel wire production mechanism can be Figure 1 or Figure 3 The tension adjustment device shown in the utility model Figure 1 or Figure 3 The description of the tension adjustment device shown should also be considered as a description of a specific embodiment of a steel wire production mechanism. When the steel wire production mechanism is in operation, at least two wires produced by the wire drawing device are transmitted to the wire take-up device via the tension adjustment device and are taken up on the same spool.

The tension adjustment device provided by this utility model can independently adjust the multiple steel wires, ensuring smooth transmission of the wires, thereby improving the manufacturing efficiency and precision of the steel cord manufacturing apparatus. Furthermore, the device features a compact design and small size, saving space and making it easier to install and apply to existing production equipment.
