Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cable production technology, specifically a photovoltaic cable winding device. Background Technology

[0002] In the production and manufacturing process of photovoltaic cables, winding is a crucial step that directly affects the subsequent storage, transportation, and ease of use of the cables.

[0003] Currently, most companies still rely on manual operation for cable winding after manufacturing. First, workers need to continuously apply tension to the cable and control the winding direction, which greatly increases labor intensity and easily leads to fatigue. Second, manual operation is relatively slow, directly reducing the overall efficiency of cable winding and making it difficult to meet the needs of large-scale production. Third, after winding, it is inconvenient to unload, affecting the continuity of the production process. In addition, during manual winding, it is impossible to effectively guide and organize the cable to be wound. The cable is prone to stacking and crossing on the winding reel, resulting in uneven cable distribution. This not only squeezes the effective space of the winding reel, wasting limited space, but may also damage the cable sheath due to excessive cable compression, affecting the insulation performance and service life of photovoltaic cables and creating hidden dangers for subsequent use.

[0018] 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.

[0019] Please see Figure 1-4 This embodiment of a photovoltaic cable winding device includes a mounting plate 1. A rotating drum 12 is mounted on the mounting plate 1 and can rotate around its own axis. A guide tube 14 is mounted at the head end of the rotating drum 12. A pulley 20 is fixedly mounted on the outer side of the rotating drum 12 and is connected to an external belt drive device. The external power drives the pulley to rotate the rotating drum 12. A key-pin type rotating shaft 13 is slidably limited and connected to the inner side of the rotating drum 12. The key-pin type rotating shaft 13 can move with the rotating drum 12. The key-pin type rotating shaft 13 rotates synchronously and can slide along the axial direction of the rotating drum 12. The head end of the key-pin type rotating shaft 13 is fixed with a winding post 15. The winding post 15 is located inside the guide drum 14 and is the direct carrier for cable winding. At the same time, the guide drum 14 is used to guide the winding post during unwinding. A pushing component is installed on the back of the mounting plate 1. The pushing component is connected to the key-pin type rotating shaft 13 and is used to drive the key-pin type rotating shaft 13 to move axially, while driving the winding post to move. The cable can be unwound after winding is completed by retracting.

[0020] like Figure 2 The pushing assembly includes two sets of pushing cylinders 19 fixed to the back of the mounting plate 1. The piston rod of the pushing cylinder 19 is fixed with a side plate 18, and a bearing 17 is fixed between the side plates 18. The inner side of the bearing 17 is fixed to the key-pin type rotating shaft 13. When the piston rod of the pushing cylinder 19 extends or retracts, it drives the key-pin type rotating shaft 13 to slide axially through the side plates 18 and the bearing 17, and the arrangement of the bearing 17 does not affect the rotation of the key-pin type rotating shaft 13.

[0021] like Figure 1 and4 The mounting plate 1 is also equipped with an upper plate 2 and a support plate 21. The upper plate 2 is equipped with a manual screw lifting mechanism 3. The lifting end of the manual screw lifting mechanism 3 is fixed with a limit plate 4. The height of the limit plate 4 can be changed by adjusting the manual screw lifting mechanism 3. The limit plate 4 is used to limit the maximum diameter of the cable winding to avoid over-winding.

[0022] The upper plate 2 has a side plate 7 fixed to its surface. A lower top cylinder 8 and a guide rod 10 are mounted on the side plate 7, with the guide rod 10 guiding the movement of the lower top plate 9. The piston rod of the lower top cylinder 8 is fixed to the lower top plate 9, which is connected to the guide rod 10. A roller 11 is mounted at the bottom of the lower top plate 9. When the lower top cylinder 8 drives the lower top plate 9 to descend, the roller 11 presses against the wound cable, compacting it and preventing loosening during winding.

[0023] In addition, a limit cylinder 5 is installed on the surface of the upper plate 2. The piston rod of the limit cylinder 5 is fixed with an insertion rod 6. A retaining plate 16 is fixed on the outer side of the rotating drum 12, and the opening of the retaining plate 16 is adapted to the insertion rod 6. When it is necessary to stop winding or unwinding the cable, the limit cylinder 5 drives the insertion rod 6 to insert into the opening of the retaining plate 16, thereby locking the rotating drum 12 and preventing it from rotating accidentally.

[0024] like Figure 3 A bidirectional moving adjustment assembly is installed on the support plate 21. A side push block 30 is installed on the moving end of the bidirectional moving adjustment assembly. A lead wire drum 31 is installed on the side push block 30. After the cable passes through the lead wire drum 31, it enters the winding post 15. The bidirectional moving adjustment assembly adjusts the cable winding direction by driving the side push block 30 and the lead wire drum 31 to move, so as to ensure that the cable is evenly distributed on the winding post 15.

[0025] The bidirectional movement adjustment assembly includes a shifting cylinder 22 mounted on a support plate 21. The piston rod of the shifting cylinder 22 is fixed to a shifting plate 25, and the shifting cylinder 22 can drive the shifting plate 25 to move in a parallel direction. A pair of fixing blocks 26 are fixed to the top of the shifting plate 25, and a pair of guide posts 27 are fixed between the fixing blocks 26. A T-shaped block 28 is inserted between the guide posts 27, and the guide posts 27 guide the movement of the T-shaped block 28. A side-push cylinder 29 is installed on the left side of the T-shaped block 28. The piston rod of the side-push cylinder 29 is fixed to the fixing block 26 on the back side, and the side-push cylinder 29 can drive the T-shaped block 28 to move. The side-push block 30 is fixed to the right side of the T-shaped block 28. Through the coordinated action of the shifting cylinder 22 and the side-push cylinder 29, the bidirectional movement adjustment of the lead tube 31 in the front, back, left, and right directions is realized.

[0026] In addition, a guide block 23 is fixed to the top of the support plate 21. A wire conduit 24 is installed inside the guide block 23. A wire hole is opened on the T-shaped block 28 opposite to the wire conduit 24. This wire hole is on the same horizontal line as the lead-in cylinder 31. The cable passes through the wire conduit 24, the wire hole of the T-shaped block 28 and the lead-in cylinder 31 in sequence to ensure the straightness of the cable delivery path and reduce friction damage.

[0027] To further explain, a guide roller 32 located below the lead tube 31 is fixed on the push plate 25. The guide roller 32 supports the cable and prevents the cable from sagging due to its own weight, which would affect the winding accuracy.

[0028] The working principle of the above embodiments is as follows:

[0029] The height of the limit plate is adjusted manually using the screw lifting mechanism to match the distance between it and the winding post to the expected winding diameter, preventing over-winding. The photovoltaic cable to be wound is then passed sequentially through the conductor tube, the wire hole on the T-block, and the lead-in drum, with the starting end of the cable wound onto the winding post. At this point, the guide rollers support the cable, ensuring stable cable transport. The external belt drive is activated, which drives the drum to rotate via the pulley. The drum, through a keyed structure, drives the keyed rotating shaft to rotate synchronously, thereby rotating the winding post and beginning the cable winding process. During winding, the shifting cylinder drives the shifting plate to move closer to the winding post and gradually retract, while the side-push cylinder drives the T-block to move back and forth. Through the combined action of these two mechanisms, the side-push block and the lead-in drum move in both directions. The movement guides the cable to be evenly distributed on the winding post, avoiding stacking or crossing. Simultaneously, the lower top cylinder can be activated to drive the lower top plate downwards, causing the rollers to press against the wound cable, compacting it and ensuring tight winding. The guide rod ensures smooth movement of the lower top plate. When the diameter of the wound cable reaches the position of the limit plate, the limit plate prevents the cable from continuing to wind. At this time, the external belt drive device is stopped, and the limit cylinder is activated to drive the insertion rod to insert into the opening of the slot plate, locking the drum and preventing accidental rotation. Finally, the push cylinder is activated, and its piston rod extends, pushing the key-pin rotating shaft axially outwards through the side plate and bearings. This, in turn, moves the winding post and the wound cable, along with the guide cylinder, out, making it easy for workers to remove the wound cable.
