Description

Technical Field

[0001] This invention patent relates to the technical field of cable traction structures. Specifically, it relates to a method for real-time tension adjustment during cable traction. Background Art

[0002] Cable traction structures are widely used in fields such as cable manufacturing. They are used to traction cables to move, so that the cables can be processed during the movement. For example, through a glue injection device, a silicone layer is covered on the cable during traction transmission.

[0003] By arranging a take-up reel and a pay-off reel, the take-up reel winds up the cable, and the pay-off reel releases the cable. Through the synchronous rotation of the take-up reel and the pay-off reel, the traction transmission of the cable is realized. The cable during traction transmission has a real-time tension to ensure that the cable is in a certain degree of tension state, so as to facilitate the processing and manufacturing of the cable.

[0004] In the prior art, during the cable traction process, the real-time tension of the cable will fluctuate greatly, and it is difficult to adjust the real-time tension of the cable, resulting in the cable being difficult to maintain a relatively stable state. In this way, the cable is difficult to be suitable for processing with specific requirements. For example, due to the large fluctuation of the real-time tension of the cable, it is difficult to form a silicone layer with a wall thickness of less than 0.25 mm on the cable, which greatly limits the development of the cable industry. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for real-time tension adjustment during cable traction, aiming to solve the problem that it is difficult to adjust the real-time tension during cable traction in the prior art.

[0006] The present invention is realized as follows. For the method for real-time tension adjustment during cable traction, the cable is arranged between the take-up reel and the pay-off reel. The take-up reel winds up the cable, and the pay-off reel releases the cable. The take-up reel and the pay-off reel rotate synchronously to enable the cable to be traction-transmitted between the take-up reel and the pay-off reel;

[0007] Counterweight wheel groups are respectively arranged on the outer sides of the take-up reel and the pay-off reel. The cable has an adjustment section wound around the outer circumference of the counterweight wheel group, and the counterweight wheel group applies a counterweight force to the adjustment section. A tension sensor for detecting the real-time tension of the cable is provided on the counterweight wheel group. A power structure is connected to the counterweight wheel group, and the power structure adjusts the counterweight force of the counterweight wheel group on the adjustment section. The tension sensor and the power structure are respectively electrically connected to a controller;

[0008] Set a predetermined tension required for the cable during traction transmission. During the traction transmission of the cable, the tension sensor monitors the real-time tension of the cable in real time and feeds back the detected real-time tension to the controller. The controller controls the power structure to adjust the gravity applied to the adjustment section by the counterweight wheel set according to the comparison between the real-time tension and the predetermined tension, so as to change the real-time tension of the cable and make the real-time tension approach the predetermined tension.

[0009] Furthermore, set a fluctuation range of the predetermined tension. The power structure adjusts the gravity applied to the adjustment section by the counterweight wheel set to change the real-time tension of the cable until the real-time tension is within the fluctuation range of the predetermined tension.

[0010] Furthermore, the adjustment section is enclosed and wound around the outer periphery of the counterweight wheel set.

[0011] Furthermore, the counterweight wheel set includes an adjustment wheel driven by the power structure to move up and down. The adjustment section bypasses the bottom of the adjustment wheel, and the adjustment wheel applies the gravity to the adjustment section; when the adjustment wheel moves upward, the gravity decreases, and the real-time tension decreases; when the adjustment wheel moves downward, the gravity increases, and the real-time tension increases.

[0012] Furthermore, the counterweight wheel set includes a fixed wheel located above the adjustment wheel. The fixed wheel is arranged at a relative interval with the adjustment wheel, and there is an interval distance between the fixed wheel and the adjustment wheel; the adjustment section movably bypasses the top of the fixed wheel and bypasses both sides of the interval distance respectively;

[0013] The power structure is connected to the adjustment wheel and applies an upward driving force to the adjustment wheel. The driving force is less than the gravity of the adjustment wheel, and the difference between the gravity of the adjustment wheel and the driving force is the gravity;

[0014] When the driving force increases, the adjustment wheel moves upward, the interval distance decreases, and the gravity decreases; when the driving force decreases, the adjustment wheel moves downward, the interval distance increases, and the gravity increases.

[0015] Furthermore, the fixed wheel is fixedly arranged.

[0016] Furthermore, the power structure includes a swing rod that swings and applies an upward driving force to the adjustment wheel. The adjustment wheel is rotatably connected to the swing rod; when the swing rod swings upward, the adjustment wheel moves upward synchronously, the driving force increases, the interval distance decreases, and the gravity decreases; when the swing rod swings downward, the adjustment wheel moves downward synchronously, the driving force decreases, the interval distance increases, and the gravity increases.

[0017] Further, the power structure includes a motor, the motor has a rotating shaft, the swing rod is fixedly connected to the rotating shaft, and the rotating shaft applies an upward driving force to the adjusting wheel through the swing rod;

[0018] When the torque applied by the rotating shaft to the swing rod increases, the swing rod swings upward and the driving force increases; when the torque applied by the rotating shaft to the swing rod decreases, the swing rod swings downward and the driving force decreases.

[0019] Further, the swing rod includes two swing bars arranged at intervals, and an elastic interval is formed between the two swing bars; the inner ends of the two swing bars are connected with a fixed end, which is integrally connected, and the outer ends of the swing bars form swing ends;

[0020] An installation head that moves elastically is provided in the elastic interval, and installation blocks extend from both ends of the installation head respectively; an installation groove is provided in the swing end, and the installation blocks are movably embedded in the installation groove; an elastic layer is wrapped outside the installation blocks, and the elastic layer presses against the inner side wall of the installation groove and is in a compressed deformation state; an installation shaft is provided in the middle of the installation head, and the adjusting wheel is rotatably connected to the installation shaft;

[0021] During the process of the swing rod swinging up and down, the driving force applied to the adjusting wheel changes, and the elastic layers on the two installation blocks elastically deform. During the process of the installation head swinging up and down synchronously with the swing rod, the installation head elastically buffers and moves up and down in the elastic interval.

[0022] Further, the installation blocks are spherical, and the elastic layers are also spherical and cover the outer surfaces of the entire installation blocks; the elastic layers are integrally embedded in the installation grooves and integrally abut against the inner side walls of the installation grooves; there are hollow strips in the swing bars, and the hollow strips extend along the length direction of the swing bars;

[0023] During the process of the swing rod swinging up and down, the driving force applied to the adjusting wheel changes, and the swing bars are synchronously bent and deformed.

[0024] Compared with the prior art, the real-time tension adjustment method for the cable traction process provided by the present invention detects the cable during the traction process through a tension sensor to obtain the real-time tension of the cable. The controller obtains the real-time tension and compares it with the set predetermined tension, and controls the power structure to adjust the gravity of the counterweight wheel set on the adjustment section; when the gravity changes, the real-time tension of the cable also changes accordingly. In this way, the real-time tension of the cable during the traction process can be adjusted to make the real-time tension approach the predetermined tension, so that the cable is in a relatively stable traction state and large fluctuations of the cable are avoided. In this way, the cable can meet the requirements of various processing conditions. Description of the Drawings

[0030] Refer to Figure 1-2 as shown, which is a preferred embodiment provided by the present invention.

[0031] A real-time tension adjustment method during the cable traction. The cable 100 is arranged between the take-up reel 300 and the pay-off reel 200. The take-up reel 300 winds up the cable 100, and the pay-off reel 200 pays out the cable 100. The take-up reel 300 and the pay-off reel 200 rotate synchronously so that the cable 100 is traction-transmitted between the take-up reel 300 and the pay-off reel 200. During the traction transmission of the cable 100, the cable 100 can be processed, etc. For example, a silicone layer is formed on the cable 100 through a gluing device.

[0032] Counterweight wheel sets 400 are respectively arranged on the outer sides of the take-up reel 300 and the pay-off reel 200. The cable 100 has an adjustment section 101 wound around the outer circumferences of the counterweight wheel sets 400, and the counterweight wheel sets 400 apply a counterweight force to the adjustment section 101; a tension sensor for detecting the real-time tension of the cable 100 is provided on the counterweight wheel sets 400.

[0033] A power structure 500 is connected to the counterweight wheel set 400. The power structure 500 adjusts the counterweight force of the counterweight wheel set 400 on the adjustment section 101. The tension sensor and the power structure 500 are respectively electrically connected to the controller.

[0034] Set the predetermined tension required for the cable 100 during the traction transmission. During the traction transmission of the cable 100, the tension sensor real-time monitors the real-time tension of the cable 100, and feeds back the detected real-time tension to the controller. The controller controls the power structure 500 to adjust the counterweight force of the counterweight wheel set 400 on the adjustment section 101 according to the comparison between the real-time tension and the predetermined tension, so as to change the real-time tension of the cable 100 and make the real-time tension approach the predetermined tension.

[0035] For the real-time tension adjustment method during the cable traction process provided above, the tension sensor detects the cable 100 during the traction process to obtain the real-time tension of the cable 100. The controller obtains the real-time tension, compares it with the set predetermined tension, and controls the power structure 500 to adjust the counterweight force of the counterweight wheel set 400 on the adjustment section 101.

[0036] When the counterweight force changes, the real-time tension of the cable 100 also changes accordingly. In this way, the real-time tension of the cable 100 during the traction process can be adjusted so that the real-time tension approaches the predetermined tension, so that the cable 100 is in a relatively stable traction state, avoiding large fluctuations in the cable 100. In this way, the cable 100 can meet the requirements of various processing conditions.

[0037] For example, when the real-time tension of the cable 100 approaches the predetermined tension and the real-time tension is adjusted in real time to avoid large fluctuations in the real-time tension, the cable 100 is in a stable traction process, so that a silicone layer with a wall thickness of less than 0.25 mm can be formed on the cable 100.

[0038] In this embodiment, set the fluctuation range of the predetermined tension. The power structure 500 adjusts the counterweight force of the counterweight wheel set 400 on the adjustment section 101 to change the real-time tension of the cable 100 until the real-time tension is within the fluctuation range of the predetermined tension. In this way, by setting the fluctuation range of the predetermined tension, for example, the predetermined tension can be set within a 5% fluctuation range, which is convenient for adjusting the real-time tension, and different fluctuation ranges can be set according to different processing requirements of the cable 100.

[0039] In this embodiment, the adjustment section 101 is enclosed and wound along the outer periphery of the counterweight wheel set 400. In this way, during the traction transmission of the cable 100, it drives around the outer periphery of the counterweight wheel set 400 and forms an enclosed winding, which is convenient for the counterweight wheel set 400 to apply a counterweight force to the adjustment section 101.

[0040] In this embodiment, the counterweight wheel set 400 includes an adjusting wheel 402 driven by a power structure 500 to move up and down. The adjusting section 101 bypasses the bottom of the adjusting wheel 402, and the adjusting wheel 402 applies a counterweight force to the adjusting section 101. When the adjusting wheel 402 moves upward, the counterweight force decreases and the real-time tension decreases. When the adjusting wheel 402 moves downward, the counterweight force increases and the real-time tension increases.

[0041] The adjusting section 101 bypasses the bottom of the adjusting wheel 402, which is convenient for the adjusting wheel 402 to apply a counterweight force to the adjusting section 101. When the adjusting section 101 is not provided on the outer periphery of the counterweight wheel set 400, at this time, under the action of its own gravity, the adjusting wheel 402 moves downward, and the adjusting section 101 supports the adjusting wheel 402 from the bottom of the adjusting wheel 402. By adjusting the adjusting wheel 402 through the power structure 500, the counterweight applied by the adjusting wheel 402 on the adjusting section 101 can be realized, thereby realizing the real-time tension adjustment of the cable 100.

[0042] In this embodiment, the counterweight wheel set 400 includes a fixed wheel 401 located above the adjusting wheel 402. The fixed wheel 401 and the adjusting wheel 402 are arranged at a relative interval, and an interval distance 403 is formed between the fixed wheel 401 and the adjusting wheel 402. The adjusting section 101 movably bypasses the top of the fixed wheel 401 and bypasses both sides of the interval distance 403 respectively.

[0043] The power structure 500 is connected to the adjusting wheel 402 and applies an upward driving force to the adjusting wheel 402. The driving force is less than the gravity of the adjusting wheel 402, and the difference between the gravity of the adjusting wheel 402 and the driving force is the above-mentioned counterweight force.

[0044] When the driving force increases, the adjusting wheel 402 moves upward, the interval distance 403 decreases, and the counterweight force decreases. When the driving force decreases, the adjusting wheel 402 moves downward, the interval distance 403 increases, and the counterweight force increases.

[0045] The power structure 500 applies a driving force to the adjusting wheel 402. Since the gravity of the adjusting wheel 402 is fixed, when the driving force changes, the counterweight force applied by the adjusting wheel 402 on the adjusting section 101 changes correspondingly, thereby realizing the real-time tension adjustment of the cable 100.

[0046] In this embodiment, the fixed wheel 401 is fixedly arranged. In this way, the fixed wheel 401 can be used as a reference for the up and down movement of the adjusting wheel 402, which is convenient for the adjustment of the adjusting wheel 402.

[0047] In this embodiment, the power structure 500 includes a swing rod 502 that is swingably arranged and applies an upward driving force to the adjusting wheel 402. The adjusting wheel 402 is rotatably connected to the swing rod 502. When the swing rod 502 swings upward, the adjusting wheel 402 moves upward synchronously, the driving force increases, the spacing 403 decreases, and the counterweight decreases. When the swing rod 502 swings downward, the adjusting wheel 402 moves downward synchronously, the driving force decreases, the spacing 403 increases, and the counterweight increases.

[0048] In this way, since the swing rod 502 is directly connected to the adjusting wheel 402, the swing of the swing rod 502 can directly drive the synchronous movement of the adjusting wheel 402, thereby directly realizing the adjustment of the driving force of the adjusting wheel 402.

[0049] In this embodiment, the power structure 500 includes a motor 501. The motor 501 has a rotating shaft. The swing rod 502 is fixedly connected to the rotating shaft. The rotating shaft applies an upward driving force to the adjusting wheel 402 through the swing rod 502. When the torque applied by the rotating shaft to the swing rod 502 increases, the swing rod 502 swings upward and the driving force increases. When the torque applied by the rotating shaft to the swing rod 502 decreases, the swing rod 502 swings downward and the driving force decreases.

[0050] Directly driving the swing of the swing rod 502 by the motor 501 can adjust the torque of the rotating shaft to realize the swing adjustment of the swing rod 502 by the motor 501, thereby realizing the adjustment of the driving force applied to the adjusting wheel 402, and the structure is simple.

[0051] In this embodiment, the swing rod 502 includes two swing bars 5021 arranged at intervals. An elastic interval 5023 is formed between the two swing bars 5021. The inner ends of the two swing bars 5021 are connected with a fixed end 5024, which is connected as a whole. The outer ends of the swing bars 5021 form swing ends 5025. When the two swing bars 5021 are subjected to an inward pressure or an outward pulling force, the two swing bars 5021 can swing inward or outward. In this way, the elastic interval 5023 between the swing bars 5021 can be changed.

[0052] An installation head 600 that moves elastically is provided in the elastic interval 5023. Installation blocks 601 extend from both ends of the installation head 600 respectively. Installation grooves are provided in the swing ends 5025, and the installation blocks 601 are movably embedded in the installation grooves. An elastic layer 602 is wrapped around the outside of the installation blocks 601. The elastic layer 602 presses against the inner side wall of the installation groove and is in a compressed deformation state. An installation shaft is provided in the middle of the installation head 600, and the adjusting wheel 402 is rotatably connected to the installation shaft.

[0053] During the up-and-down swing of the swing rod 502, the driving force applied to the adjusting wheel 402 changes, and the elastic layers 602 on the two mounting blocks 601 elastically deform. During the process of the mounting head 600 swinging up and down synchronously with the swing rod 502, the mounting head 600 elastically buffers and moves up and down in the elastic interval 5023.

[0054] In this way, when the swing rod 502 drives the adjusting wheel 402 to swing synchronously, the driving force applied to the adjusting wheel 402 and the gravity applied by the adjusting wheel 402 to the adjusting section 101 also change synchronously. Therefore, the acting force on the elastic layer 602 of the mounting block 601 also changes accordingly, and the mounting head 600 can elastically buffer and move in the elastic interval 5023 to achieve elastic buffer adjustment of the gravity, without forming a rigid adjustment, avoiding sudden pulling on the cable 100, and realizing elastic buffer adjustment of the real-time tension of the cable 100, so that the whole adjustment process is more gentle.

[0055] In this embodiment, the mounting block 601 is spherical, and the elastic layer 602 is also spherical, covering the outer surface of the entire mounting block 601; the elastic layer 602 is integrally embedded in the mounting groove and abuts against the inner side wall of the mounting groove; the swing bar 5021 has a hollow bar, and the hollow bar extends along the length direction of the swing bar 5021; during the up-and-down swing of the swing rod 502, the driving force applied to the adjusting wheel 402 changes, and the swing bar 5021 synchronously bends and deforms.

[0056] The mounting block 601 is spherical, and the elastic layer 602 covers the outer surface of the entire mounting block 601 and abuts against the inner side wall of the mounting groove as a whole. In this way, it is ensured that the mounting block 601 can elastically deform in the full range of space. During the swing of the swing rod 502, the elastic layer 602 can elastically deform in the space, and better realize the full-range elastic buffer adjustment of the real-time tension of the cable 100.

[0057] In addition, by arranging the hollow bar, the elastic deformation ability of the swing bar 5021 is increased. During the swing of the swing rod 502, the elastic buffer adjustment of the real-time tension of the cable 100 can be realized through the synchronous bending deformation of the swing bar 5021.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
