Description

Technical Field

[0001] The utility model relates to the technical field of cable pay-off mechanisms, in particular to a cable pay-off mechanism with multiple guide wheels. Background Art

[0002] A cable is a type of wire used to transmit electricity. Most of its interior is made up of multiple strands of wire wrapped together. Therefore, during the cable production process, when multiple strands of wire are wrapped together, it is usually necessary to use a wire-paying mechanism to pay out the single strands of wire so that multiple single strands of wire can be wrapped around each other to form a cable.

[0003] For example, the patent with the announcement number CN210312851U discloses a cable stranding pay-off stand. Although the pay-off stand fixes the first bracket to a specified position and then puts the cable on a turntable, when the direction of pulling the wire changes, the second bracket rotates on the first bracket to maintain the same direction, so that the wire can be pulled in multiple directions, which brings convenience to cable manufacturing; however, in actual use, the cable on the turntable lacks support and tension when it is released from the pay-off stand, so that the released cable is in a suspended state, which can easily lead to unstable cable pay-off. Utility Model Content

[0029] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0030] The following is combined with Figure 1-Figure 7 This embodiment is described in further detail.

[0031] See also Figure 1-Figure 2, a cable pay-off mechanism with multiple guide wheels in this embodiment includes a fixed frame 100, on which are provided multiple groups of pay-off assemblies; the pay-off assembly includes a wire drum carrying shaft 101 rotatably provided on the fixed frame 100, and the wire drum carrying shaft 101 is used to support the cable drum 102, and the pay-off assembly also includes a guide member provided on the fixed frame 100, which is used to guide the cable paid out from the cable drum 102; the guide member includes a rotatable first guide wheel 130, a second guide wheel 150 and a movable direction adjustment wheel 140, and a column 110 is provided at the upper end of the fixed frame 100, and the column 110 is provided with a wire outlet wheel 111 for centralized output of the cables passing through the direction adjustment wheel 140, and the direction adjustment wheel 140 is used to transport the cables guided by the first guide wheel 130 and the second guide wheel 150 to the wire outlet wheel 111 at different angles.

[0032] In this embodiment, when the cables on multiple cable reels 102 need to be paid out collectively, the cable reels 102 are fixed to the corresponding cable reel bearing shafts 101, and the cable reel bearing shafts 101 are rotated so that the cables thereon are guided by the guide members and then paid out from the discharge wheel 111;

[0033] Specifically, the cable released from the outlet wheel 111 is stranded and reeled under the action of an existing cable stranding machine, thereby allowing the cable on the cable pay-off mechanism to be paid out;

[0034] Among them, through the setting of the guide part, when the cables on multiple cable reels 102 are moving, they are guided by the first guide wheel 130 and the second guide wheel 150, and then pass through the corresponding direction adjustment wheel 140 and the outlet wheel 111, and are finally released in a concentrated manner. Compared with the existing embodiment, when this embodiment is in use, since the cables are wound around the first guide wheel 130, the second guide wheel 150 and the direction adjustment wheel 140, there is a large friction between the cables and the first guide wheel 130, the second guide wheel 150 and the direction adjustment wheel 140, making it difficult for the cables to separate from the first guide wheel 130, the second guide wheel 150 and the direction adjustment wheel 140, so that the cables released from the cable reel 102 are supported and tensioned, making their release more stable.

[0035] Combine Figure 1-6 In this embodiment, the guide member also includes a fixed block 220 arranged on the fixed frame 100, and a rotatable swing arm 120 is provided on the fixed block 220. A rotatable tensioning wheel 121 is provided at one end of the swing arm 120, and a driving member is provided on the swing arm 120 for maintaining balance with the rotating cable.

[0036] In this embodiment, the outer side wall of the tensioning wheel 121 is provided with a first groove 230 and a second groove 231 along its circumference, the first guide wheel 130 is provided with a third groove 300, and the second guide wheel 150 is provided with a fourth groove 400. As a result, in actual use, the cable released from the cable reel 102 passes through the first groove 230 and enters the third groove 300, then passes through the second groove 231 and enters the fourth groove 400, and finally passes through the direction adjustment wheel 140 and enters the outlet wheel 111 to complete the pay-out. After the cable is wound around the first guide wheel 130, the second guide wheel 150 and the tensioning wheel 121 multiple times, the contact between the cable and the first guide wheel 130 and the second guide wheel 150 can be more sufficient, thereby increasing the friction force and making the cable pay-out more stable.

[0037] Among them, a bearing is provided on the side of the fixed block 220 close to the swing arm 120, and a fixing rod is provided on the swing arm 120 that extends into the corresponding bearing, thereby realizing the rotatable setting of the swing arm 120 on the fixed block 220; when the cable paid out from the cable reel 102 passes through the tensioning wheel 121, due to the certain pay-off speed of the cable, the tensioning wheel 121 is subjected to force, and the tensioning wheel 121 drives one end of the swing arm 120 to swing upward. At this time, the driving member can drive one end of the swing arm 120 to swing downward, so that it remains in a balanced state, thereby tensioning the cable;

[0038] In actual use of this embodiment, the first groove 230 and the third groove 300 are located at the same horizontal plane, and the second groove 231 and the fourth groove 400 are located at the same horizontal plane. Through the above structure, the cables will not interfere with each other when they are wound around the first guide wheel 130, the second guide wheel 150 and the tensioning wheel 121, so as to avoid affecting the subsequent movement of the cables.

[0039] The fixing frame 100 is provided with a plurality of fixed shafts, and the first guide wheel 130 and the second guide wheel 150 are both rotatably connected to the fixed shafts via bearings, thereby enabling the two to rotate on the fixing frame 100.

[0040] Combine Figure 3 As shown, in this embodiment, the side surfaces of the swing arm 120 are provided with sliding grooves 200 relatively along the length direction thereof; the driving member includes a counterweight block 210 slidably arranged on the swing arm 120, and a sliding block is provided on the side surface of the counterweight block 210 for sliding in the corresponding sliding groove 200. The counterweight block 210 slides along the sliding groove 200 to keep the swing arm 120 balanced. A bolt 211 is threadedly connected to the counterweight block 210, and one end of the bolt 211 is pressed against the swing arm 120 to fix the position of the counterweight block 210.

[0041] In this embodiment, when the rotation speed of the cable reel 102 increases, the tension on the tensioning wheel 121 increases, and one end of the swing arm 120 swings upward. At this time, the bolt 211 can be loosened to make the counterweight 210 slide along the swing arm 120 and move the counterweight 210 toward the tensioning wheel 121. Since the fixed rod is rotatably connected to the fixed block 220, a lever is formed between the two ends of the swing arm 120 and the fixed rod. When the counterweight 210 moves toward one end of the swing arm 120, the gravity on one end of the swing arm 120 will change. When it is equal to the tension on the cable, the tensioning wheel 121 is in its current position, so that the cable on it can remain tensioned. When the rotation speed of the cable reel 102 decreases, the counterweight 210 can be moved in the opposite direction, so that the cable on it can remain tensioned.

[0042] Combine Figure 3 As shown, in this embodiment, an upper limit post 104 and a lower limit post are relatively provided on the fixing frame 100 for limiting the rotation of the swing arm 120 .

[0043] In this embodiment, by setting the upper limit column 104 and the lower limit column, when the swing arm 120 rotates on the fixed frame 100, the swing arm 120 can only move to the bottom of the upper limit column 104 at the highest and to the top of the lower limit column at the lowest, thereby limiting the rotation distance of the swing arm 120.

[0044] Combine Figure 7 As shown, in this embodiment, a connecting shaft 600 is provided at the front end surface of the fixing frame 100, and a rotatable bracket 620 is provided on the connecting shaft 600. The direction adjustment wheel 140 is rotatably provided on the bracket 620. An annular hole 601 is provided on the connecting shaft 600, and a connecting rod 610 extending into the annular hole 601 is provided on the bracket 620. The bracket 620 rotates on the connecting shaft 600 to adjust the direction of the direction adjustment wheel 140.

[0045] In this embodiment, a bearing is provided in the annular hole 601, and the connecting rod 610 extends into the corresponding bearing, thereby enabling the connecting rod 610 to rotate around the annular hole 601, thereby achieving the rotatable installation of the bracket 620 on the connecting shaft 600;

[0046] Among them, one side of the bracket 620 extends upward to form a support plate 621, and a fixed shaft is provided between the support plates 621. The direction adjustment wheel 140 is rotatably mounted on the fixed shaft through a bearing, thereby enabling the direction adjustment wheel 140 to rotate on the fixed shaft, and the bracket 620 to rotate around the annular hole 601. When the cables on the cable reel 102 at different positions pass through the first guide wheel 130 and the second guide wheel 150, the direction of the cables passing through the direction adjustment wheel 140 can be changed by rotating the bracket 620, and finally the cables enter the outlet wheel 111 at different angles, so as to prevent multiple cables from being entangled with each other on the outlet wheel 111 and affecting the movement of the cables.

[0047] Among them, the outer side wall of the outlet wheel 111 is provided with a plurality of outlet grooves 500 along its circumference. When the cable passes through the outlet wheel 111, the cable can be stuck in the corresponding outlet groove 500, thereby preventing adjacent cables from being entangled with each other and affecting the progress of the pay-off work.

[0048] Combine Figure 1 As shown, in this embodiment, the cable reel 102 is provided with a through hole for the reel carrying shaft 101 to pass through, the inner wall of the through hole is provided with sliding grooves along its axial direction, the reel carrying shaft 101 is provided with a sliding block sliding in the corresponding sliding groove, the end of the reel carrying shaft 101 close to the fixed frame 100 is provided with a limit plate 105, and the end of the reel carrying shaft 101 away from the fixed frame 100 is provided with a nut 103 for fixing the cable reel 102.

[0049] In this embodiment, when the cables on the cable reel 102 need to be paid out in a centralized manner, the through hole is first aligned with the reel bearing shaft 101, and then the sliding block is aligned with the slide groove and slid in, and the cable reel 102 is placed on the reel bearing shaft 101. One end of the reel bearing shaft 101 is provided with a thread, and the nut 103 is threadedly connected to the reel bearing shaft 101, so that the cable reel 102 is limited on the limiting disk 105 by the nut 103. At this time, the reel bearing shaft 101 rotates, and the sliding block cooperates with the slide groove to drive the cable reel 102 to rotate;

[0050] In order to drive the drum bearing shaft 101 to rotate, a motor (not shown in the figure) is provided on one side of the fixing frame 100 .

[0051] Working principle: When concentrating cables on multiple cable reels 102, first fix the reel bearing shaft 101 on the reel bearing shaft 101, so that the cable passes through the tensioning wheel 121 and goes around the first guide wheel 130, goes back to the tensioning wheel 121, passes through the second guide wheel 150, passes through the direction adjustment wheel 140, and finally passes through the outlet groove 500 to escape from the outlet wheel 111.

[0052] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of coverage of the present patent.
