Description
Technical Field
[0001] The present invention relates to the technical field of cable production, and more specifically, to a film covering device for photovoltaic cable production. Background Art
[0002] During the production of cables, a protective film is wrapped around the cables. The protective film is used to isolate the inside and outside of the cables to achieve insulation inside the cables. Currently, after the protective film is wound, the connection effect between the wound protective films is poor. When the installer disassembles and installs one end of the cable, the protective film wrapped inside will fall off the cable due to the poor connection effect between the film strips, and the scattered protective film will affect the insulation of the cable, thereby affecting the normal use of the cable in the later stage. Therefore, a device is needed to process the film strips wound around the cable to make the film strips wound around the cable stably connected. Summary of the Invention
[0003] The purpose of the present invention is to provide a film covering device for photovoltaic cable production to solve the problems raised in the above background art.
[0004] To achieve the above purpose, a film covering device for photovoltaic cable production is provided, including a film covering device through which the cable passes inside. A film strip is provided on the film covering device, and the film covering device rotates and covers the film strip on the cable. A pressing roller device is installed on the film covering device, and a heating ring is provided on one side of the pressing roller device. One end of the cable passes through the heating ring and the pressing roller device in sequence. The heating ring heats the cable after the film covering device has covered the film, and after the heating ring has completed heating the cable, the pressing roller device presses the film strip wound on the cable, and after the film strip is pressed, the pressing roller device performs dot pressing on the film strip to fix the rotationally wound film strips together. At the same time, an adjusting mechanism is provided on the film covering device, and the adjusting mechanism adjusts the distance between the pressing roller device and the heating ring according to the size of the cable to control the temperature of the film strip when the pressing roller device presses the film strip on the cable.
[0005] As a further improvement of this technical solution, the film covering device includes a fixed ring. A support frame is fixed to the lower side of the fixed ring, and the support frame is fixed to the ground. A rotating ring is rotatably provided inside the fixed ring. A toothed ring is fixed to the side wall of the rotating ring near the end. A driving motor is installed on the support frame, and a gear is installed on the rotating shaft of the driving motor. The gear meshes with the toothed ring, and the rotating shaft of the driving motor drives the gear, and drives the rotating ring to rotate in the fixed ring through the meshing of the gear and the toothed ring.
[0006] As a further improvement of the technical solution, two mounting pins are symmetrically fixed on the left and right sides of one side of the rotating ring. Both mounting pins are inclined. The film tape is arranged on the mounting pins. One end of the cable passes through the middle position of the rotating ring, and one end of the film tape is wound around the cable. The rotating ring drives the mounting pins to rotate, so that the film tape is wound around the cable.
[0007] As a further improvement of the technical solution, when the film tape on the two mounting pins is wound, it covers and winds half of the width of the film tape on the cable.
[0008] As a further improvement of the technical solution, the pressure roller device includes a fixed pipe and a side pipe fixed at one end of the fixed pipe. A plurality of pressure roller rods are annularly arranged and hinged on the side wall of the side pipe far from the fixed pipe. A torsion spring is arranged at the position where the pressure roller rod is hinged to the side pipe. The torsion spring drives one end of the pressure roller rod to rotate towards the position close to the central axis of the side pipe. At the same time, a pressure roller is rotatably connected to one end of the pressure roller rod. When the cable passes through the side pipe, the pressure roller presses the film tape on the surface of the cable, so that the heated film tapes are pressed together.
[0009] As a further improvement of the technical solution, a plurality of pressure point members are arranged at the end of the fixed pipe far from the side pipe. The plurality of pressure point members are annularly arranged at one end of the fixed pipe. The pressure point member includes a pressing plate hinged on the side wall of the end of the fixed pipe. A pressure point piece is rotatably connected to one end of the pressing plate. A plurality of pressing blocks are fixed at the edge position of the pressure point piece.
[0010] As a further improvement of the technical solution, a plurality of fixing strips corresponding to the pressing plates are fixed on the side wall of the end of the fixed pipe far from the side pipe. An arc-shaped spring is connected between the fixing strip and the pressing plate. The arc-shaped spring pushes one end of the pressing plate close to the central axis of the fixed pipe, so that the pressure point piece contacts the film tape on the cable. During the movement of the cable, the pressing blocks on the pressure point piece press out pressing points on the film tape.
[0011] As a further improvement of the technical solution, the adjusting mechanism includes a positioning ring. The central axes of the positioning ring, the rotating ring and the side pipe are the same straight line, and the heating ring is installed at the position of the positioning ring close to the rotating ring. A plurality of telescopic rods are annularly arranged on the side of the positioning ring far from the rotating ring. The telescopic rod is composed of a sliding rod and a sliding sleeve.
[0012] As a further improvement of the technical solution, one end of the sliding rod is hinged on the side wall of the positioning ring, and one end of the sliding sleeve is hinged at the connection position of the fixed pipe and the side pipe. The pressure roller device adjusts the distance from the heating ring according to the size of the cable to control the temperature of the film tape when the pressure roller of the pressure roller device presses the film tape.
[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In the film covering device for photovoltaic cable production, by controlling the rotation speed of the rotating ring, when the installation pin rotates to adjust the film tape to wind around the cable, half of the newly wound film tape on the cable covers the film tape already wound on the cable. Then, the film tape is heated by the heating ring, and then the wound film tapes are roll-pressed by the roll-pressing device, so that the film tapes are connected together by negative pressure. When one end of the cable is disassembled by the installer, the connected film tapes will not fall off from the cable. The installer cuts the film tape according to the required length to ensure the normal subsequent use of the cable.
[0014] 2. In the film covering device for photovoltaic cable production, when the roll-pressing device roll-presses the film tape heated by the heating ring, first, the roll-pressing wheel is used to roll-press the heated film tape to make the heated film tapes adhere together. After the film tape is roll-pressed, the film tape is point-pressed by the pressing point piece to fix the film tape wound on the cable together. When the installer disassembles one end of the cable, the fixed film tapes will not fall off, ensuring the effective insulation protection of the cable interior by the protective film.
[0015] 3. In the film covering device for photovoltaic cable production, the adjusting structure drives the roll-pressing device to move on one side of the heating ring, so as to change the distance between the roll-pressing device and the heating ring. When the heating ring heats the film tape on the cable, due to the different heating effects of the film tapes on cables of different sizes by the heating ring, by adjusting the distance between the roll-pressing device and the heating ring, the temperature on the film tape when the roll-pressing device roll-presses the film tape is controlled to ensure that the film tapes are roll-pressed together by the roll-pressing device.

Embodiment
[0020] In order to stably fix the film tape on the cable, please refer to Figures 1-6 As shown, the purpose of this embodiment is to provide a film coating device for photovoltaic cable production, including a film coating device 1. The cable passes through the inside of the film coating device 1. A film tape is provided on the film coating device 1. The film coating device 1 rotates and covers the film tape on the cable. A pressure roller device 2 is installed on the film coating device 1, and a heating ring 3 is provided on one side of the pressure roller device 2. One end of the cable passes through the heating ring 3 and the pressure roller device 2 in sequence. The heating ring 3 heats the cable after the film coating device 1 has completed film coating. After the heating ring 3 has completed heating the cable, the pressure roller device 2 rolls the film tape wound on the cable, and after the film tape has been rolled, the pressure roller device 2 performs dot rolling on the film tape to fix the rotationally wound film tape together. At the same time, an adjustment mechanism is provided on the film coating device 1. The adjustment mechanism adjusts the distance between the pressure roller device 2 and the heating ring 3 according to the size of the cable, and controls the temperature of the film tape when the pressure roller device 2 rolls the film tape on the pressure roller cable.
[0021] The film tape is wound around the cable by controlling the film covering device 1, and then the film tape is heated by the heating ring 3 to soften the film tape. Then, the pressed roller device 2 is used to roll the wound film tape, so that the softened film tapes are connected together by negative pressure, thereby completing the connection between the film tapes. When one end of the cable is disassembled by the installer, the connected film tapes will not come off the cable. The installer cuts the film tape according to the required length to ensure the normal subsequent use of the cable. By adjusting the distance between the pressed roller device 2 and the heating ring 3, the temperature of the film tape when the pressed roller device 2 rolls the film tape is controlled to ensure that the film tapes are rolled together by the pressed roller device 2.
[0022] The structures of the film covering device 1 and the pressed roller device 2 are refined below to enable the pressed roller device 2 to effectively roll the film tape. The film covering device 1 includes a fixed ring 12. A support frame is fixed to the lower side of the fixed ring 12, and the support frame is fixed to the ground. A rotating ring 13 is rotatably arranged inside the fixed ring 12. A toothed ring 15 is fixed to the side wall of the rotating ring 13 near the end. A driving motor 16 is installed on the support frame. A gear is installed on the rotating shaft of the driving motor 16, and the gear meshes with the toothed ring 15. The rotating shaft of the driving motor 16 drives the gear, and the rotating ring 13 is driven to rotate in the fixed ring 12 through the meshing of the gear and the toothed ring 15. At the same time, two mounting pins 14 are symmetrically fixed on the left and right sides of one side of the rotating ring 13. Both mounting pins 14 are inclined, and the inclined direction is that the end of the mounting pin 14 away from the rotating ring 13 inclines towards the direction close to the central axis of the rotating ring 13. The film tape is arranged on the mounting pins 14. The inclined mounting pins 14 are convenient for changing the angle at which the film tape mounted on the mounting pins 14 is wound around the cable, so as to facilitate the accurate winding of the film tape around the cable. One end of the cable passes through the middle position of the rotating ring 13, and one end of the film tape is wound around the cable. The rotating ring 13 drives the mounting pins 14 to rotate, so that the film tape is wound around the cable. When the film tapes on the two mounting pins 14 are wound, they both cover half of the width of the film tape on the cable already wound, that is, half of the newly wound film tape covers the film tape already wound on the cable. As Figure 7 shown, by winding in this way, there will be no gap between the film tapes, ensuring effective insulation protection of the cable by the film tapes. At the same time, by covering and connecting the film tapes together, when the pressed roller device 2 rolls the film tape on the cable, the film tapes can be connected together.
[0023] The pressure roller device 2 includes a fixed tube 21 and a side tube 22 fixed to one end of the fixed tube 21. A plurality of pressure roller rods 24 are annularly arranged and hinged on the side wall of the end of the side tube 22 far from the fixed tube 21. A torsion spring is arranged at the position where the pressure roller rod 24 is hinged to the side tube 22. The torsion spring drives one end of the pressure roller rod 24 to rotate towards the position close to the central axis of the side tube 22. At the same time, a pressure roller 25 is rotatably connected to one end of the pressure roller rod 24. When the cable passes through the side tube 22, the pressure roller 25 presses the film belt on the surface of the cable, so that the heated film belts are pressed together. The pressed-together film belts will adhere to each other and form an integral body, so that when one end of the cable is disassembled by the installer, the connected film belts will not fall off from the cable. The installer intercepts the film belt according to the required length to ensure the normal subsequent use of the cable.
[0024] In order to improve the connection effect between the film belts, a plurality of pressure point members are arranged at the end of the fixed tube 21 far from the side tube 22. The plurality of pressure point members are annularly arrayed at one end of the fixed tube 21. The pressure point member includes a pressing plate 26 hinged on the side wall of the end of the fixed tube 21. One end of the pressing plate 26 is rotatably connected with a pressure point piece 27. A plurality of pressing blocks are fixed at the edge position of the pressure point piece 27. A plurality of fixing strips 23 corresponding to the pressing plate 26 are fixed on the side wall of the end of the fixed tube 21 far from the side tube 22. An arc spring 28 is connected between the fixing strip 23 and the pressing plate 26. The arc spring 28 pushes one end of the pressing plate 26 close to the central axis of the fixed tube 21, so that the pressure point piece 27 contacts the film belt on the cable. During the movement of the cable, the pressing blocks on the pressure point piece 27 press out pressing points on the film belt.
[0025] The pressing blocks on the pressure point piece 27 press out pressing points on the film belt one by one. The film belt at the pressing points is under great pressure, making the connection between the film belts like welding, further improving the connection effect between the film belts.
[0026] Considering that the device will apply film to cables of different sizes, and the distances between the film belts on large-sized cables and small-sized cables from the side wall of the heating ring 3 are different, and the heating effects on the film belts are also different. The film belt on the large-sized cable is close to the heating ring 3, and the heating ring 3 has a good heating effect on the film belt on the large-sized cable. At this time, the film belt is soft after being heated inside. When the pressure roller device 2 squeezes the overly soft film belt, it is easy to deform the film belt. At the same time, the overly soft film belt is easy to adhere to the pressure roller device 2, affecting the normal use of the pressure roller device 2. Therefore, an adjustment mechanism is designed to adjust the position of the pressure roller device 2, so that the adjustment structure drives the pressure roller device 2 to move on one side of the heating ring 3, thereby changing the distance between the pressure roller device 2 and the heating ring 3. Changing the distance between the pressure roller device 2 and the heating ring 3 will change the heat dissipation time of the film belt, thereby controlling the softness of the film belt after being heated and ensuring the effective pressing of the film belt by the pressure roller device 2.
[0027] The structure of the adjusting mechanism is refined as follows. The adjusting mechanism includes a positioning ring 11. The central axes of the positioning ring 11, the rotating ring 13, and the side pipe 22 are on the same straight line, and the heating ring 3 is installed at a position of the positioning ring 11 close to the rotating ring 13. A plurality of telescopic rods 17 are arranged in a circular pattern on the side of the positioning ring 11 away from the rotating ring 13. The telescopic rod 17 is composed of a sliding rod and a sliding sleeve. One end of the sliding rod is hinged to the side wall of the positioning ring 11, and one end of the sliding sleeve is hinged to the connection position of the fixed pipe 21 and the side pipe 22. The pressing roller device 2 adjusts the distance from the heating ring 3 according to the size of the cable to control the temperature on the film tape when the pressing roller of the pressing roller device 2 presses the film tape. When changing the position of the pressing roller device 2, the sliding rod slides in the sliding sleeve to change the overall length of the telescopic rod 17. The lengths of the plurality of telescopic rods 17 are the same during adjustment to ensure that the pressing roller device 2 moves on the central axis of the heating ring 3. At the same time, after the position adjustment of the pressing roller device 2 is completed, the position of the pressing roller device 2 on one side of the positioning ring 11 is fixed by fixing the position of the sliding rod in the sliding sleeve.
