Description

Technical Field

[0001] This utility model belongs to the field of unwinding machine technology, and in particular relates to a photovoltaic cable unwinding machine. Background Technology

[0002] In the production and laying of photovoltaic cables, the unwinding machine is an indispensable key piece of equipment, and its performance directly affects the efficiency and quality of cable unwinding.

[0003] Traditional photovoltaic cable unwinding machines have many shortcomings in structure and function. Traditional tensioning devices often use fixed support structures, making it difficult to adapt to cable reels with different inner diameters, and the tensioning force is not uniform enough, easily leading to cable misalignment or wrinkling during unwinding. Some photovoltaic cable unwinding machines also commonly suffer from inconvenient tensioning mechanism adjustment and insufficient tensioning force uniformity. For example, tensioning devices using simple screw and nut adjustments are prone to slippage and jamming of the tensioning seat during long-term high-speed unwinding, causing tension fluctuations in the cable reel and leading to cable wrinkling, breakage, and other malfunctions. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a photovoltaic cable unwinding machine. By improving the structural design of the tensioning mechanism and the suspension mechanism, it achieves adaptive tensioning of the cable reel sleeve, thereby improving the stability and reliability of the unwinding process.

[0005] The present invention adopts the following technical solution:

[0006] The photovoltaic cable unwinding machine includes a base, on which an unwinding shaft is rotatably mounted. One end of the unwinding shaft is provided with a tensioning mechanism, and the other end is provided with a suspension mechanism. The tensioning mechanism includes a baffle and a tensioning seat disposed inside and outside the unwinding shaft. The tensioning seat can move along the length of the unwinding shaft. The baffle is provided with a ring of guide grooves. The tensioning seat is provided with a short plate corresponding to each guide groove. A pair of rotating plates are provided on the short plates. A T-shaped support seat is rotatably mounted on the same pair of rotating plates. One end of the T-shaped support seat is located inside the guide groove, and the other end is provided with a baffle.

[0007] Furthermore, the unwinding shaft has an adjusting threaded section, the tensioning seat has an adjusting threaded hole, and the end of the tensioning seat is provided with an adjusting rotary disc.

[0008] Furthermore, the T-shaped support has a notch located within a guide groove, and the T-shaped support is provided with rotatable limit wheels on both the inner and outer sides of the guide groove.

[0009] Furthermore, the hovering mechanism includes a stop disc fixedly mounted on the unwinding shaft. A fixed seat is provided on the side wall of the machine base opposite the stop disc. A rotating shaft is provided inside the fixed seat. Inner and outer clamping arms are rotatably mounted on the rotating shaft. A clamping seat is rotatably mounted above each clamping arm. The stop disc is located between the inner and outer clamping seats. An adjusting screw is screwed into the lower part of one clamping arm. The end of the adjusting screw is rotatably mounted on the other clamping arm.

[0010] Furthermore, the bottom of the baffle has a guide groove that matches the top of the T-shaped support. A locking screw is screwed into the bottom of the baffle, and the end of the locking screw is screwed out of the guide groove and matches the T-shaped support.

[0011] The beneficial effects of this utility model are:

[0012] 1. By rotating the adjustment disc, the tensioning seat moves along the adjusting thread section, causing the T-shaped support seat to slide radially in the guide groove, so that the baffle is evenly pressed against the inner wall of the cable reel sleeve with different inner diameters, realizing stepless adjustment and uniform distribution of tension force, and avoiding cable deviation.

[0013] 2. By adjusting the screws to drive the inner and outer clamping arms to swing, the clamping force of the clamping seat on the stop plate can be precisely controlled, so as to achieve smooth start and stop of the unwinding shaft, avoid sudden changes in cable reel tension, and improve processing accuracy.

[0016] Figure 3 This utility model provides a schematic diagram of a tensioning mechanism. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0019] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0020] Combination Figure 1-3As shown, the photovoltaic cable unwinding machine includes a base 1, on which an unwinding shaft 2 is rotatably mounted. One end of the unwinding shaft 2 is provided with a tensioning mechanism, and the other end is provided with a suspension mechanism. The tensioning mechanism includes a baffle 3 and a tensioning seat 4 disposed inside and outside the unwinding shaft 2. The tensioning seat 4 can move along the length direction of the unwinding shaft 2. The baffle 3 is provided with a ring of guide grooves 5. The tensioning seat 4 is provided with a short plate 6 corresponding to each guide groove 5. A pair of rotating plates 7 are provided on the short plates 6. A T-shaped support seat 8 is rotatably mounted on the same pair of rotating plates 7. One end of the T-shaped support seat 8 is located inside the guide groove 5, and the other end is provided with a baffle 9.

[0021] In the figure, there are three guide grooves, and three corresponding short plates. Each short plate is equipped with a T-shaped support seat that rotates through a pair of rotating plates. One end of the T-shaped support seat is located in the guide groove, and the other end is equipped with a baffle.

[0022] Before use, the short plate is in the starting position, that is, at the bottom of the guide groove. Remove the baffle from each T-shaped support. Place the cable reel on the three short plates, and then install the baffles on the T-shaped support, with the cable reel positioned between the baffle and the three baffles. Next, the tensioning seat moves towards the baffle, causing the short plate, rotating plate, and T-shaped support to move. Guided by the guide groove, the T-shaped support moves outward and upward, with the three T-shaped support pressing against the inner wall of the cable reel, achieving tension and fixation. During unwinding, the rotation speed and hovering state of the unwinding shaft are controlled by the suspension mechanism, achieving precise control of the cable unwinding process.

[0023] In this structure, the unwinding shaft 2 has an adjusting threaded section, and the tensioning seat 4 has an adjusting threaded hole (not shown in the figure). The end of the tensioning seat 4 is provided with an adjusting rotary disk 10. By cooperating with the adjusting threaded section and the adjusting threaded hole, the tensioning seat can move along the length direction of the unwinding shaft. The adjusting rotary disk at the end of the tensioning seat facilitates manual rotation of the tensioning seat by the operator to realize its movement.

[0024] As a preferred structure, such as Figure 3 The T-shaped support 8 has a notch 11, which facilitates the T-shaped support being positioned and installed within the guide groove. The T-shaped support 8 is equipped with rotatable limiting wheels 12 on both the inner and outer sides of the guide groove. When the T-shaped support moves along the guide groove, the limiting wheels roll, reducing friction between the T-shaped support and the guide groove, making the movement of the T-shaped support smoother. Simultaneously, they limit the movement of the T-shaped support, ensuring it moves along the direction of the guide groove.

[0025] In this device, the bottom of the baffle 9 has a guide groove 13 that matches the top of the T-shaped support. A locking screw 14 is screwed into the bottom of the baffle 9, and the end of the locking screw 14 extends out of the guide groove 13 and matches the T-shaped support 8. The guide groove and locking screw secure the baffle to the T-shaped support, preventing it from loosening during tensioning and ensuring the stability of the tensioning mechanism.

[0026] Furthermore, as a preferred structure, such as Figure 1 The hovering mechanism includes a stop disc 15 fixedly mounted on the unwinding shaft 2. A fixed seat 16 is provided on the side wall of the base 1 opposite the stop disc 15. A rotating shaft 17 is provided inside the fixed seat 16. Inner and outer clamping arms 18 are rotatably mounted on the rotating shaft 17. A clamping seat 19 is rotatably mounted above each clamping arm 18. The stop disc 15 is located between the inner and outer clamping seats 19. An adjusting screw 20 is screwed into the lower part of one clamping arm 18. The end of the adjusting screw 20 is rotatably mounted on the other clamping arm 18.

[0027] During use, the angle between the inner and outer clamping arms can be changed by turning the adjusting screw, thereby clamping or releasing the stop disc and achieving suspension control of the unwinding shaft. When it is necessary to stop unwinding, tighten the adjusting screw to clamp the stop disc and prevent the unwinding shaft from rotating; when it is necessary to continue unwinding, loosen the adjusting screw, the clamp releases the stop disc, and the unwinding shaft can rotate freely.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
