Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cable processing technology, and in particular to an automatic winding machine for insulating tape of photovoltaic cables. Background Technology

[0002] Photovoltaic cables are wires and cables specifically designed to connect solar photovoltaic modules and inverters, as well as other components of a photovoltaic system. They play a crucial role in transmitting electrical energy within the photovoltaic system. During the production process of photovoltaic cables, insulating tape is wrapped around the outside of the cable to improve its insulation and protective performance.

[0003] The existing winding device requires workers to connect the two ends of the winding column to the support frame at both ends through a rotating bearing and a placement slot. The winding requires manual operation by hand cranking the handle. After winding, disassembly is difficult, and the labor intensity is still very high and the efficiency is still very low.

[0004] The existing patent (publication number: CN209583243U) discloses an automatic cable winding machine, including a motor and a gearbox mounted on a base. The output end of the gearbox is connected to a reduction shaft, which is connected to a detachable rotating shaft via a flange. The detachable rotating shaft is mounted on a rotating shaft bracket and has a cable carrying device for supporting the cable reel. This automatic cable winding machine adopts a detachable rotating shaft and a detachable cable carrying device design, which facilitates movement in different construction environments and allows for easy unloading of the cable reel. The transmission design of the motor, reduction gearbox, and detachable rotating shaft is simple and stable, improving the efficiency of cable winding and reducing manual labor.

[0005] To address the aforementioned issues, existing patents offer solutions. However, the wrapping of insulating tape on the surface of existing photovoltaic cables is mostly done manually, which is inefficient. Furthermore, due to different operating habits of operators, manual wrapping can easily lead to inconsistent tightness and uneven number of wrapping layers. Although automatic wrapping equipment is used in some cases, existing automatic wrapping equipment has a complex structure, is difficult to operate and debug, has high maintenance costs, and is poorly adaptable to photovoltaic cables of different specifications.

[0006] Therefore, an automatic insulation tape winding machine for photovoltaic cables is proposed. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An automatic winding machine for insulating tape of photovoltaic cables includes a base 1, a winding mechanism 2 on the top of the base 1, and transmission guide components 3 on both sides of the top of the base 1.

[0029] The winding mechanism 2 includes a support plate 201, which is fixedly connected to the top of the base 1. A rotating drum 202 is rotatably connected inside the support plate 201 via a bearing. A transmission assembly 203 that works with the rotating drum 202 is provided on the right side of the support plate 201. A turntable 204 is fixedly connected to the left side of the surface of the rotating drum 202. A support rod 205 is rotatably connected to the bottom inside the turntable 204 via a damping bearing. A positioning ring 206 is fixedly connected to the right side of the surface of the support rod 205. A locking ring 207 is threadedly connected to the left side of the surface of the support rod 205. A tension guide wheel 208 is rotatably connected to the front side inside the turntable 204 via a bearing.

[0030] In this embodiment: by setting a base 1, a winding mechanism 2, and a transmission guide component 3, the base 1 can support and fix the winding mechanism 2 and the transmission guide component 3 during use. The winding mechanism 2 can automatically wind the insulating tape onto the surface of the photovoltaic cable, effectively improving the winding efficiency. Moreover, the operation is relatively simple, bringing convenience to the operator. In addition, the structure is simple and the maintenance cost is low. The transmission guide component 3 can guide and continuously transport the photovoltaic cable that needs to be wound with insulating tape, so that the winding mechanism 2 can continuously wind the photovoltaic cable with insulating tape.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the transmission guide assembly 3 includes a first upright plate 301 and a second upright plate 302. The first upright plate 301 and the second upright plate 302 are respectively fixedly connected to the front and rear sides of the top of the base 1. A transmission roller 303 is rotatably connected between the first upright plate 301 and the second upright plate 302 through a bearing. A reduction motor 304 is fixedly connected to the front side of the first upright plate 301. The output shaft of the reduction motor 304 is fixedly connected to the front end of the transmission roller 303.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a pressure roller 305 is provided on the top of the transmission roller 303. The front and rear sides of the pressure roller 305 are rotatably connected to a fixed block 306 via bearings. Limiting grooves 307 are provided on the surfaces of both the transmission roller 303 and the pressure roller 305.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, support blocks 308 are fixedly connected to the top of the opposite side of the first upright plate 301 and the second upright plate 302. A pressing cylinder 309 is fixedly connected to the bottom of the support block 308. The output rod of the pressing cylinder 309 is fixedly connected to the top of the fixing block 306.

[0034] In this embodiment: by setting up a first upright plate 301, a second upright plate 302, a transmission roller 303, a reduction motor 304, a pressure roller 305, a fixing block 306, a limiting groove 307, a support block 308, and a pressing cylinder 309, in use, the first upright plate 301 and the second upright plate 302 can support and fix the transmission roller 303, the reduction motor 304, and the support block 308. Then, the photovoltaic cable that needs to be wrapped with insulating tape passes between the pressure roller 305 and the transmission roller 303 and is located in the limiting groove 307. Then, the pressing cylinder 309 is activated, causing the output of the pressing cylinder 309 to be activated. The rod drives the fixed block 306 to move down, and the fixed block 306 drives the pressure roller 305 to move down, so that the pressure roller 305 presses the photovoltaic cable through the transmission roller 303. Then, the reduction motor 304 can be started, so that the output shaft of the reduction motor 304 drives the transmission roller 303 to rotate. The rotation of the transmission roller 303 can continuously transport the photovoltaic cable under the action of friction, so that the winding mechanism 2 can continuously wind the photovoltaic cable with insulation tape. The setting of the limiting groove 307 can guide and limit the photovoltaic cable to prevent the photovoltaic cable from deviating during the transmission process.

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the transmission assembly 203 includes a drive motor 203a, which is fixedly connected to the bottom of the right side of the support plate 201, and the output shaft of the drive motor 203a is fixedly connected to a transmission gear 203b.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, the top of the transmission gear 203b is meshed with a driven gear 203c, which is sleeved on the right side of the surface of the rotating drum 202. The inner wall of the driven gear 203c is fixedly connected to the surface of the rotating drum 202.

[0037] In this embodiment: by setting up a drive motor 203a, a transmission gear 203b and a driven gear 203c, when in use, by starting the drive motor 203a, the output shaft of the drive motor 203a drives the transmission gear 203b to rotate. At this time, the transmission gear 203b will drive the driven gear 203c that meshes with it to rotate, so that the driven gear 203c can drive the rotating drum 202 to rotate.

[0038] Specifically, such as Figure 1 , Figure 2 As shown, support legs 4 are fixedly connected to the four corners of the bottom of the base 1, and shock-absorbing pads 5 are fixedly connected to the bottom of the support legs 4.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, reinforcing support plates 6 are fixedly connected to the front and rear sides of the bottom of both sides of the support plate 201, and the side of the reinforcing support plate 6 closest to the base 1 is fixedly connected to the base 1.

[0040] In this embodiment: by setting support legs 4, the base 1 can be stably supported; by setting shock-absorbing pads 5, the vibration generated by the equipment during winding can be reduced; and by setting reinforcing support plates 6, the stability of support plates 201 can be improved.

[0041] Working principle: In use, the photovoltaic cable to be wrapped with insulating tape is passed sequentially between one set of pressure rollers 305 and transmission rollers 303, then through the rotating drum 202, and finally out between another set of pressure rollers 305 and transmission rollers 303, ensuring the photovoltaic cable is positioned within the limiting groove 307. Then, the clamping cylinder 309 is activated, causing its output rod to move the fixing block 306 downwards. The fixing block 306 then moves the pressure rollers 305 downwards, causing them to press the photovoltaic cable firmly against the transmission rollers 303. The insulating tape reel is placed on the surface of the support rod 205 and fitted against the positioning ring 206. Then, the locking ring 207 is placed on the surface of the support rod 205 and rotated, causing the locking ring 207 to lock and fix the insulating tape reel via threaded movement. Next, one end of the insulating tape is wrapped around the surface of the tension guide wheel 208 and fixed to the surface of the photovoltaic cable. Then, the drive motor 203a is started, causing its output shaft to drive the transmission gear 203b to rotate. At this time, the transmission gear 203b will drive the driven gear 203, which is meshed with it. The rotation of gear c causes the driven gear 203c to drive the rotating drum 202 to rotate. The rotating drum 202 drives the turntable 204 to rotate, which in turn drives the support rod 205 and the tension guide wheel 208 to move in a circular motion. This allows the insulating tape to be wound around the surface of the photovoltaic cable. During the winding process, the support rod 205 rotates with resistance under the action of the damping bearing, and the tension guide wheel 208 rotates under the action of the bearing. The tension guide wheel 208 can limit and guide the insulating tape and provide winding tension. During the winding process, two sets of reduction motors 304 can be started by the same controller, so that the output shafts of the two reduction motors 304 rotate at the same speed. The output shafts of the reduction motors 304 drive the transmission roller 303 to rotate. The rotation of the transmission roller 303 can continuously and slowly convey the photovoltaic cable under the action of friction. This allows the winding mechanism 2 to continuously wind the photovoltaic cable with insulating tape, effectively improving the winding efficiency. Moreover, the operation is relatively simple, bringing convenience to the operator. In addition, the structure is simple and the maintenance cost is low.

[0042] The above are merely preferred embodiments of the present utility model and are 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.
