Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a tension buffer mechanism for a cable storage rack used in cable production. Background Technology

[0002] In the cable production process, the cable is typically released by an unwinding machine, processed by the equipment, and then wound up by a winding machine. However, as the diameter of the wire on the winding reel gradually increases while the diameter of the wire on the unwinding reel gradually decreases during winding, it becomes difficult to dynamically match the speeds of the unwinding and winding machines. If the unwinding speed is less than the winding speed, the cable will be overstretched, resulting in excessively tight winding or even breakage; if the unwinding speed is greater than the winding speed, the cable will be loose, resulting in excessively loose winding or accumulation, severely affecting the winding quality and production efficiency of the cable.

[0003] To address the aforementioned problems, various tension control schemes have been proposed in the prior art. For example, patent CN210393264U discloses a tension adjustment device that utilizes the coordinated action of pulley blocks, chains, counterweights, and springs. This device achieves dynamic adjustment of cable tension by using multiple sets of movable pulleys and fixed pulleys on a movable and fixed tripod, combined with a first chain, a second chain, and a tension buffer spring. Specifically, a motor drives the sprocket to move the chain, the counterweight and spring provide buffering force, and the tension is adjusted by the vertical displacement of the pulleys, thereby ensuring smooth winding. However, this scheme has the following significant drawbacks:

[0004] Because pulley blocks require multiple stages of arrangement in both the horizontal and vertical directions, the equipment structure is relatively large, making it difficult to deploy flexibly, especially when production space is limited. At the same time, the number of components such as movable pulleys, fixed pulleys, and chains increases exponentially, which not only increases manufacturing costs but also increases maintenance complexity. Utility Model Content

[0005] The purpose of this invention is to provide a tension buffer mechanism for a cable storage rack used in cable production, so as to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The system includes a base plate, a support assembly mounted on the top surface of the base plate, a main roller assembly mounted on one end of the support assembly, a driven roller assembly mounted on the other end of the support assembly, a cable wound in a figure-eight shape around the surfaces of the main roller assembly and the driven roller assembly, and a pressure roller assembly mounted on one side of the driven roller assembly. The support assembly includes a first support leg and a second support leg respectively fixed to the top surface of the base plate, a first crossbar fixed to the top surface of the first support leg, a main roller assembly mounted on one side of the first crossbar, a rectangular hole set at one end of the first crossbar, a track fixed to the top surface of the second support leg, a second crossbar sliding on the track, a rectangular rod fixed to one end of the second crossbar, a rectangular rod sliding in the rectangular hole, a dovetail groove set on one side of the second crossbar, and a driven roller assembly sliding within the dovetail groove.

[0008] As a preferred embodiment, a first protrusion is fixedly connected to the other side of the first crossbar, and a second protrusion is fixedly connected to the other side of the second crossbar. An adjusting threaded rod is internally threaded to the second protrusion, and one end of the adjusting threaded rod is rotatably connected to one side of the first protrusion.

[0009] Preferably, the main roller assembly includes a main roller and a drive motor. The main roller is rotatably connected to one side of the first crossbar. The main roller has main grooves evenly spaced on its circumferential surface. The drive motor is fixedly connected to one side of the first crossbar. The output shaft of the drive motor is rotatably connected to the main roller through a worm gear and worm wheel.

[0010] Preferably, the driven roller assembly includes a dovetail block, which is slidably connected in the dovetail groove, and a driven roller is rotatably connected to one side of the dovetail block. Driven grooves are evenly spaced on the circumferential surface of the driven roller.

[0011] Preferably, the roller assembly also includes a tension threaded rod, which rotates within the dovetail groove. A long rod is threadedly connected to the surface of the tension threaded rod, and one end of the long rod passes through the dovetail block and is fixedly connected to a rectangular plate. Two ends of one side of the rectangular plate are respectively fixedly connected to buffer damping rods, and one end of the buffer damping rod is in contact with one side of the dovetail block.

[0012] Preferably, the pressure roller assembly includes an extension rod, one side of the dovetail block is fixedly connected to the extension rod, one end of the extension rod is fixedly connected to a vertical plate, one side of the vertical plate is provided with a vertical groove, a vertical block is slidably connected in the vertical groove, an anti-detachment wheel is rotatably connected to the lower part of one side of the vertical block, an avoidance groove is provided to the upper part of one side of the vertical block, an avoidance damping rod is fixedly connected in the avoidance groove, one end of the avoidance damping rod is fixedly connected to an avoidance block, and one side of the avoidance block is rotatably connected to a retaining wheel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By rotating the adjusting threaded rod, the second crossbar will move, and the second crossbar will move, which will in turn move the driven roller assembly and the pressure roller assembly, thereby adjusting the distance between the driven roller assembly and the main roller to ensure the tension during cable conveying.

[0015] 2. By rotating the tensioning threaded rod, the tensioning threaded rod drives the long rod to slide inside the dovetail block, thereby driving the rectangular plate and the buffer damping rod to move closer to the dovetail block and squeeze the dovetail block, causing the buffer damping rod to contract. In this way, the cable between the main roller and the driven roller is tightened. At the same time, when the cable between the main roller and the driven roller is loose, the contracted buffer damping rod will drive the driven roller to move away from the main roller, thus tightening the cable. When the cable between the main roller and the driven roller is tight, the driven roller will drive the dovetail block to squeeze the buffer damping rod again to achieve partial buffering.

[0016] 3. By cooperating with the rollers, damping rods, clearance blocks and anti-detachment wheels, the cable can be limited, avoiding the cable from coming off the main trough or the trough due to vibration during cable transportation, thus ensuring the stability of the overall transportation.

[0017] 4. When the vertical block slides on the vertical groove, and the external cable feeding wheel feeds the cable quickly, the vertical block will drive the entire structure, including the retaining wheel and the anti-detachment wheel, to move downwards, thereby tightening the cable.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example: This utility model provides a technical solution for a tension buffer mechanism in a cable storage rack for cable production, such as... Figures 1-6 As shown, it includes: a base plate 100, a support assembly 200 mounted on the top surface of the base plate 100, a main roller assembly 300 mounted on one end of the support assembly 200, a driven roller assembly 400 mounted on the other end of the support assembly 200, a cable 500 wound in a figure-eight pattern around the surfaces of the main roller assembly 300 and the driven roller assembly 400, and a pressure roller assembly 600 mounted on one side of the driven roller assembly 400; the support assembly 200 includes a first support leg 201 and a second support leg 202 respectively fixed to the top surface of the base plate 100, and fixed to the first... The first crossbar 203 on the top surface of the support leg 201, the main roller assembly 300 installed on one side of the first crossbar 203, the rectangular hole 204 set at one end of the first crossbar 203, the track 205 fixed to the top surface of the second support leg 202, the second crossbar 206 sliding on the track 205, the rectangular rod 207 fixed at one end of the second crossbar 206, the rectangular rod 207 sliding in the rectangular hole 204, the dovetail groove 208 set on one side of the second crossbar 206, and the slave roller assembly 400 sliding in the dovetail groove 208.

[0033] By using a figure-eight winding of the cable, this device is less expensive and occupies less space compared to the traditional method of using multiple tensioning rollers.

[0034] like Figure 2 As shown, a first protrusion 209 is fixedly connected to the other side of the first crossbar 203, and a second protrusion 210 is fixedly connected to the other side of the second crossbar 206. An adjusting threaded rod 211 is internally threaded to the second protrusion 210, and one end of the adjusting threaded rod 211 is rotatably connected to one side of the first protrusion 209.

[0035] By rotating the adjusting threaded rod 211, the second crossbar 206 will move. When the second crossbar 206 moves, it will move the slave roller assembly 400 and the pressure roller assembly 600, thereby adjusting the distance between the slave roller assembly 400 and the main roller 300 to ensure the tension during cable conveying.

[0036] like Figure 3 As shown, the main roller assembly 300 includes a main roller 301 and a drive motor 302. The main roller 301 is rotatably connected to one side of the first crossbar 203. Main grooves 303 are evenly spaced on the circumferential surface of the main roller 301. The drive motor 302 is fixedly connected to one side of the first crossbar 203. The output shaft of the drive motor 302 is rotatably connected to the main roller 301 through a worm gear and worm wheel. The driven roller assembly 400 includes a dovetail block 401. The dovetail block 401 is slidably connected in the dovetail groove 208. A driven roller 402 is rotatably connected to one side of the dovetail block 401. Driven grooves 403 are evenly spaced on the circumferential surface of the driven roller 402.

[0037] The main roller 301 is driven to rotate by the drive motor 302. When the main roller 301 rotates, it can better transport the cable.

[0038] like Figure 4 and Figure 5 As shown, the roller assembly 400 also includes a tension threaded rod 404, which rotates within the dovetail groove 208. A long rod 405 is threadedly connected to the surface of the tension threaded rod 404. One end of the long rod 405 passes through the dovetail block 401 and is fixedly connected to a rectangular plate 406. Two ends of one side of the rectangular plate 406 are respectively fixedly connected to a buffer damping rod 407. One end of the buffer damping rod 407 is in contact with one side of the dovetail block 401.

[0039] By rotating the tension threaded rod 404, the tension threaded rod 404 drives the long rod 405 to slide within the dovetail block 401, thereby causing the rectangular plate 406 and the buffer damping rod 407 to move closer to the dovetail block 401 and squeeze the dovetail block 401, causing the buffer damping rod 407 to partially contract. In this way, the cable between the main roller 301 and the driven roller 402 is tightened. At the same time, when the cable between the main roller 301 and the driven roller 402 is relatively loose, the contracted buffer damping rod 407 will drive the driven roller 402 to move away from the main roller 301, thus tightening the cable. When the cable between the main roller 301 and the driven roller 402 is relatively tight, the driven roller 402 will drive the dovetail block 401 to squeeze the buffer damping rod 407 again to achieve partial buffering.

[0040] like Figure 6 As shown, the pressure roller assembly 600 includes an extension rod 601. The extension rod 601 is fixedly connected to one side of the dovetail block 401. A vertical plate 602 is fixedly connected to one end of the extension rod 601. A vertical groove 603 is provided on one side of the vertical plate 602. A vertical block 604 is slidably connected in the vertical groove 603. An anti-detachment wheel 605 is rotatably connected to the lower part of one side of the vertical block 604. An avoidance groove 606 is provided on the upper part of one side of the vertical block 604. An avoidance damping rod 607 is fixedly connected in the avoidance groove 606. An avoidance block 608 is fixedly connected to one end of the avoidance damping rod 607. A chuck 609 is rotatably connected to one side of the avoidance block 608.

[0041] By cooperating with the 609 chuck, the 607 avoidance damping rod, the 608 avoidance block and the 605 anti-detachment wheel, the cable can be limited, which avoids the cable from coming off the main cable tray 303 or the cable tray 403 due to shaking during cable transportation, thus ensuring the stability of the overall transportation.

[0042] When the vertical block 604 slides on the vertical groove 603, and the external wire feeding wheel feeds the wire quickly, the vertical block 604 will drive the entire structure, including the retaining wheel 609 and the anti-derailment wheel 605, to move downwards, thereby tightening the cable.

[0043] Specifically, in use, firstly, the operator can adjust the distance between the main roller assembly 300 and the driven roller 400 according to the requirements. During adjustment, it is only necessary to rotate the adjusting threaded rod 211. When the adjusting threaded rod 211 rotates, it will drive the second crossbar 206 to slide on the track 205. When the second crossbar 206 moves, it will also drive the driven roller assembly 400 and the rectangular rod 207 to move respectively. When the rectangular rod 207 moves, it will slide in the rectangular hole 204. When the driven roller assembly 400 moves, the distance between the driven roller assembly 400 and the main roller assembly 300 will be adjusted. After adjustment;

[0044] At this point, the worker passes one end of cable 500 between the chuck 609 and the anti-detachment wheel 605. After passing through, cable 500 passes through the first main groove 303 on the main roller 301 and into the first slave groove 403 above the slave roller 402. Then, the cable travels along the surface of the slave roller 402 to its underside. At this point, the cable passes under the slave roller 402 and then above the surface of the main roller 301. After multiple windings, the cable forms a figure-eight winding between the main roller 301 and the slave roller 402. Finally, one end of cable 500 is output from the top of the slave roller 402 and connected to external equipment.

[0045] At this point, the staff can adjust the threaded rod 211 by rotating it or tighten the threaded rod 404 according to the force applied to the cable winding.

[0046] When the adjusting threaded rod 211 is rotated, it will drive the second crossbar 206 to move. When the second crossbar 206 moves, it will drive the tensioning threaded rod 404, the long rod 405, and the rectangular plate 406 to move. At this time, the driven roller 402 will be unable to move under the action of the cable. When the rectangular plate 406 moves, it will cause the buffer damping rod 407 to be squeezed. When the buffer damping rod 407 is squeezed;

[0047] When the tension threaded rod 404 rotates, it drives the shovel rod 405 and the rectangular plate 406 to move. When the rectangular plate 406 moves, it will cause the buffer damping rod 407 to squeeze the dovetail block 401, and at the same time, the buffer damping rod 407 will partially compress and shrink.

[0048] At this point, the drive motor 302 can be started. When the drive motor 302 is working, it will drive the main roller 301 to rotate and start conveying the cable 500.

[0049] When the cable between the main roller 301 and the driven roller 402 is too tight, the cable 500 will pull the driven roller 402 to move. When the driven roller 402 moves, it will squeeze the buffer damping rod 407 again, thereby preventing the cable from being pulled and damaged.

[0050] When the cable between the main roller 301 and the driven roller 402 is too loose, the buffer damping rod 407 will squeeze the driven tube 402 to start tensioning the cable 500. At the same time, the chuck 609, the anti-derailment roller 605 and the clearance block 608 will slide downward in the vertical groove 603 under the action of weight, which will also achieve tensioning of the cable 500 and ensure the tension of the cable 500.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
