Description

Technical Field

[0001] This utility model relates to the technical field of cable insulation coating, and in particular to a photovoltaic cable insulation coating device. Background Technology

[0002] Photovoltaic cables mainly consist of a conductor, insulation layer, braided layer, and sheath. During photovoltaic cable production, an insulation layer needs to be coated onto the outer layer of the conductor core. Chinese utility model patent CN220189333U discloses an automatic insulation coating device for wires and cables. This device includes a main platform and a molding detection mechanism. An extrusion coating machine is mounted on the top of the main platform. The extrusion coating machine has an inlet hole on its right end and a coating outlet hole on its left end. The molding detection mechanism is located on the top of the main platform. This utility model provides an automatic insulation coating device for wires and cables. By setting up a molding detection mechanism, the coated wires and cables are guided and transported through a guide groove. After the wires and cables fall into the guide groove, a laser detector controls a laser emitter to emit a laser to detect the insulation layer on the wires and cables, monitoring the quality of the cable insulation layer in real time, promptly identifying and correcting abnormalities in the production process. When an abnormality is detected in the insulation coating, the laser detector controls a buzzing alarm to alert the workers.

[0003] However, the molding discs of the aforementioned automatic wire and cable insulation coating devices are arranged horizontally relative to each other. When the molding discs shape the cable insulation layer, two extrusion flat pieces or seams are generated on both sides of the cable insulation layer. The extruded flat pieces are not conducive to the smooth progress of subsequent processes such as wrapping the insulation layer, and the straight seams make the insulation layer prone to cracking. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a photovoltaic cable insulation coating device that improves the molding effect and reduces the risk of insulation layer cracking by rolling the cable insulation layer along a spiral path.

[0005] This utility model discloses a photovoltaic cable insulation coating device, comprising a base plate and an extrusion coating machine. The extrusion coating machine is mounted on the base plate, and the cable conductor core passes through the extrusion coating machine. The extrusion coating machine is used to heat-melt the insulation material and coat the insulation material onto the conductor core. It also includes a roller frame, a turntable, two forming wheels, two shafts, and a drive mechanism. The roller frame is mounted on the base plate, and the turntable is rotatably mounted on the roller frame. The turntable is concentrically aligned with the output port of the extrusion coating machine. An opening is provided in the center of the turntable. The two forming wheels are rotatably mounted in the opening of the turntable via the two shafts. Each of the edge surfaces of the two forming wheels has an annular forming groove. The edge surfaces of the two forming wheels roll in contact, and the two forming grooves on the edge surfaces of the two forming wheels are aligned to form a circular channel. This channel is aligned with the output port of the extrusion coating machine. The drive mechanism is mounted on the base plate. The drive mechanism drives the turntable to rotate. During operation, insulating material is added to the hopper of the extrusion coating machine, and the conductor core passes through the extrusion coating machine. The extrusion coating machine heats and melts the insulating material and coats it on the outer wall of the conductor core. The conductor core with the insulating layer is output from the extrusion coating machine and passes through the circular channel between the edge surfaces of the two forming wheels. The forming grooves of the two forming wheels roll and shape the insulating layer. At the same time, the drive mechanism drives the turntable to rotate on the roller frame, so that the turntable drives the two forming wheels to rotate around the conductor core through the two shafts, thereby shaping the insulating layer along a spiral path. The two forming wheels roll and shape the insulating layer in both axial and circumferential directions, which can eliminate flat sheets or seams on both sides of the insulating layer, resulting in a better shaping effect of the insulating layer. This facilitates the smooth progress of subsequent processes such as wrapping the insulation layer and reduces the risk of cracking of the insulating layer.

[0006] Preferably, it also includes a second roller frame, a second turntable, two second forming wheels, and two second shafts. The second roller frame is mounted on the base plate and is located behind the first roller frame. The second turntable is rotatably mounted on the second roller frame and is concentrically arranged with the first roller frame. An opening is provided in the center of the second turntable. The two second forming wheels are rotatably mounted in the openings of the second turntable via the two second shafts. Each of the two second forming wheels has a forming groove on its edge surface. The edge surfaces of the two second forming wheels roll in contact, and the two forming grooves on the edge surfaces of the two second forming wheels are aligned to form a circular channel. The channel is aligned with the output port of the extrusion coating machine. The two second forming wheels are arranged perpendicularly to the two first forming wheels. The drive mechanism drives the roller frame. Turntable 2 rotates in the opposite direction to turntable 1; after being shaped by the two shaping wheels 1, the conductor core extends out of the channels of the two shaping wheels 1 and passes through the circular channel 2 between the edge surfaces of the two shaping wheels 2. The shaping grooves of the two turntables 2 perform secondary rolling shaping on the insulation layer. The drive mechanism drives turntable 2 to rotate in the opposite direction to turntable 1. Turntable 2 drives the two shaping wheels 2 to rotate in the opposite direction through the two shafts 2, thereby causing the two shaping wheels 2 to rotate around the conductor core, thus performing shaping processing on the insulation layer along a spiral path. The two shaping wheels 2 perform secondary rolling shaping on the insulation layer in the axial and circumferential directions, further eliminating flat sheets or seams on both sides of the insulation layer, and further improving the shaping effect of the insulation layer.

[0007] Preferably, the drive mechanism includes a motor, a first bevel gear, a first drive wheel, a second bevel gear, a third drive wheel, and a fourth bevel gear. The motor is mounted on the base plate, and the first bevel gear is concentrically mounted on the output shaft of the motor.

The motor drives the first bevel gear to rotate, and the first bevel gear meshes with the second bevel gear to drive the first drive wheel to rotate forward. At the same time, the first bevel gear meshes with the third bevel gear to drive the second drive wheel to rotate in reverse, thereby enabling the first and second turntables to rotate in opposite directions.

[0008] Preferably, it also includes a fan, which is mounted on bracket three on the base plate and is located between turntable one and turntable two; the fan blows air onto the cable between turntable one and turntable two to cool it down and improve the setting speed of the insulation layer.

[0009] Preferably, the device also includes a powder coating pipe, a powder feeding flat pipe, brushes, and a powder hopper. The powder coating pipe is mounted on a base plate via a bracket and has a powder coating channel. The powder feeding flat pipe is mounted on the powder coating pipe, and a brush is installed at the lower end of the powder feeding flat pipe, extending into the powder coating channel of the powder coating pipe. The powder hopper is mounted on the powder feeding flat pipe and is used to convey powder to the powder feeding flat pipe. The powder hopper stores powder for cable insulation protection, such as talc powder. The powder is conveyed to the powder feeding flat pipe through the lower port of the powder hopper. The powder feeding flat pipe evenly distributes the powder onto multiple brushes. When the cable passes through the powder coating channel of the powder coating pipe, the multiple brushes apply the powder to the surface of the cable insulation layer to protect the cable insulation layer.

[0010] Preferably, it also includes a slot and a baffle. A powder outlet is provided at the bottom of the powder coating channel of the powder coating pipe. The slot is installed on the lower end face of the powder coating pipe. A slot matching the slot is provided at the upper end of the powder hopper.

The baffle is opened to the side, and the lower port of the powder hopper is detachably installed on the upper port of the powder feeding flat pipe, so that the powder hopper conveys powder to the powder feeding flat pipe. It has good practicality.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the insulating material is added to the hopper of the extrusion coating machine, and the conductor core passes through the extrusion coating machine. The extrusion coating machine heats and melts the insulating material and coats it on the outer wall of the conductor core. The conductor core with the insulating layer is output from the extrusion coating machine and passes through the circular channel between the edge surfaces of the two molding wheels. The molding grooves of the two molding wheels roll and mold the insulating layer. At the same time, the drive mechanism drives the turntable to rotate on the roller frame, so that the turntable drives the two molding wheels to rotate around the conductor core through the two shafts, thereby molding the insulating layer along the spiral path. The two molding wheels roll and mold the insulating layer in the axial and circumferential directions, which can eliminate the flat pieces or seams on both sides of the insulating layer, resulting in a better molding effect of the insulating layer. This facilitates the smooth progress of subsequent processes such as wrapping the programming layer and reduces the risk of cracking of the insulating layer. Attached Figure Description

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figures 1 to 5As shown, a photovoltaic cable insulation coating device includes a base plate 1 and an extrusion coating machine 2. The extrusion coating machine 2 is mounted on the base plate 1, and the cable conductor core passes through the extrusion coating machine 2. The extrusion coating machine 2 is used to heat-melt the insulation material and coat the insulation material onto the conductor core. It also includes a roller frame 3, a turntable 4, two molding wheels 5, two shafts 6, and a drive mechanism. The roller frame 3 is mounted on the base plate 1, and the turntable 4 is rotatably mounted on the roller frame 3. The turntable 4 is concentrically aligned with the output port of the extrusion coating machine 2. An opening is provided in the center of the turntable 4, and the two molding wheels 5 are rotatably mounted on the turntable via the two shafts 6. In the opening of 4, annular molding grooves are provided on the edge surfaces of the two molding wheels 5. The edge surfaces of the two molding wheels 5 roll in contact, and the two molding grooves on the edge surfaces of the two molding wheels 5 are aligned to form a circular channel. The channel is aligned with the output port of the extrusion coating machine 2. The drive mechanism is mounted on the base plate 1, and the drive mechanism drives the turntable 4 to rotate. It also includes a roller frame 7, a turntable 8, two molding wheels 9, and two shafts 10. The roller frame 7 is mounted on the base plate 1 and is located behind the roller frame 3. The turntable 8 is rotatably mounted on the roller frame 7 and is concentrically arranged with the turntable 4. An opening 2 is provided in the middle of turntable 8. Two molding wheels 2 9 are rotatably mounted in the opening 2 of turntable 8 via two shafts 2 10. Molding grooves 2 are provided on the edge surfaces of the two molding wheels 2 9. The edge surfaces of the two molding wheels 2 9 roll in contact. The two molding grooves 2 on the edge surfaces of the two molding wheels 2 9 are aligned to form a circular channel 2. The channel 2 is aligned with the output port of extrusion coating machine 2. The two molding wheels 2 9 are arranged perpendicularly to the two molding wheels 1 5. The drive mechanism drives turntable 2 8 to rotate in the opposite direction to turntable 1 4. The drive mechanism includes a motor 11, a bevel gear 12, a drive wheel 13, a bevel gear 2 14, and a drive... Wheel 15 and bevel gear 16 are mounted on the base plate 1. Motor 11 is mounted on the base plate 1. Bevel gear 12 is mounted concentrically on the output shaft of motor 11. Drive wheel 13 is rotatably mounted on the bracket 1 of the base plate 1 via shaft 1. Drive wheel 13 is connected to turntable 4. Bevel gear 14 is concentrically mounted on shaft 1 of drive wheel 13. Bevel gear 14 meshes with bevel gear 12. Drive wheel 15 is rotatably mounted on bracket 2 of the base plate 1 via shaft 2. Drive wheel 15 is connected to turntable 8. Bevel gear 16 is concentrically mounted on shaft 2 of drive wheel 15. Bevel gear 16 meshes with bevel gear 12.

[0023] During operation, motor 11 drives bevel gear 12 to rotate. Bevel gear 12 meshes with bevel gear 14, driving drive wheel 13 to rotate forward. Simultaneously, bevel gear 12 meshes with bevel gear 16, driving drive wheel 15 to rotate in reverse. This causes turntable 14 and turntable 28 to rotate in opposite directions. Insulating material is added to the hopper of extrusion coating machine 2. The conductor core passes through extrusion coating machine 2. Extrusion coating machine 2 heats and melts the insulating material, coating it onto the outer wall of the conductor core. The conductor core, coated with the insulating layer, exits extrusion coating machine 2 and passes through the circular channel between the edge surfaces of two molding wheels 15. The molding grooves of the two molding wheels 15 roll and shape the insulating layer. Turntable 14 rotates on roller frame 13, causing turntable 14 to drive the two molding wheels 15 to rotate around the conductor core via two shafts 16, thereby molding the insulating layer along a spiral path. The process involves two molding wheels 5 rolling and molding the insulation layer in both axial and circumferential directions. After being molded by the two molding wheels 5, the conductor core extends out of the channels of the two molding wheels 5 and passes through the circular channel 2 between the edge surfaces of the two molding wheels 9. The molding grooves of the two turntables 8 perform secondary rolling and molding of the insulation layer. The drive mechanism drives the turntables 8 to rotate in the opposite direction to the turntables 4. The turntables 8 drive the two molding wheels 9 to rotate in the opposite direction through the two shafts 10, thereby causing the two molding wheels 9 to rotate around the conductor core. This process shapes the insulation layer along a spiral path. The secondary rolling and molding of the insulation layer by the two molding wheels 9 in both axial and circumferential directions can eliminate flat sheets or seams on both sides of the insulation layer, resulting in a better molding effect. This facilitates subsequent processes such as wrapping the programming layer and reduces the risk of insulation layer cracking.

[0024] Example 2

[0025] like Figure 3 As shown, based on embodiment 1, it also includes a fan 17, which is mounted on bracket 3 of base plate 1 and located between turntable 4 and turntable 8. The fan 17 blows air to the cable between turntable 4 and turntable 8 to cool it down and improve the setting speed of the insulation layer.

[0026] Example 3

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, based on Embodiment 1, it also includes a powder coating pipe 18, a powder feeding flat pipe 19, a brush 20, and a powder hopper 21. The powder coating pipe 18 is mounted on the base plate 1 via a bracket. The powder coating pipe 18 is provided with a powder coating channel. The powder feeding flat pipe 19 is mounted on the powder coating pipe 18. The brush 20 is installed at the lower end of the powder feeding flat pipe 19 and extends into the powder coating channel of the powder coating pipe 18. The powder hopper 21 is mounted on the powder feeding flat pipe 19 and is used to convey powder to the powder feeding flat pipe 19. It also includes a slot 22 and a baffle 23. The bottom of the powder coating channel of the powder coating pipe 18 is provided with a powder outlet. The slot 22 is installed on the lower end face of the powder coating pipe 18. The upper end of the powder hopper 21 is provided with a slot that matches the slot 22. The baffle 23 is slidably mounted on the lower port of the powder hopper 21 and closes the lower port of the powder hopper 21.

[0028] The powder hopper 21 stores powder for cable insulation protection, such as talc powder. The baffle 23 is opened to the side, and the lower port of the powder hopper 21 is detachably installed on the upper port of the powder feeding flat tube 19. The powder is conveyed to the powder feeding flat tube 19 through the lower port of the powder hopper 21. The powder feeding flat tube 19 evenly distributes the powder onto multiple brushes 20. When the cable passes through the powder coating channel of the powder coating tube 18, the multiple brushes 20 apply the powder to the surface of the cable insulation layer to protect the cable insulation layer. The powder hopper 21 is inserted into the lower port of the powder coating tube 18 through the slot 22. The baffle 23 closes the lower port of the powder hopper 21, so that the excess powder in the powder coating tube 18 falls into the powder hopper 21 through the powder outlet. The excess powder is recycled, so that the powder hopper 21 conveys powder to the powder feeding flat tube 19.

[0029] like Figures 1 to 7 As shown, this utility model discloses a photovoltaic cable insulation coating device. During operation, insulating material is first added to the hopper of an extrusion coating machine 2. The conductor core passes through the extrusion coating machine 2, which heats and melts the insulating material, coating it onto the outer wall of the conductor core. Afterward, the conductor core coated with the insulation layer exits the extrusion coating machine 2 and passes sequentially through the circular channel and channel 2 between the edge surfaces of two forming wheels 5 and two turntables 8. Then, the forming grooves of the two forming wheels 5 and the two turntables 8 roll and shape the insulation layer. Simultaneously, the drive mechanism drives the rotating... Disk 4 and turntable 8 rotate in opposite directions, causing turntable 4 to drive two molding wheels 5 to rotate around the conductive core via two shafts 6, and turntable 8 to drive two molding wheels 9 to rotate around the conductive core in opposite directions via two shafts 10. This process shapes the insulation layer along a spiral path, allowing the two molding wheels 5 and 9 to roll and shape the insulation layer in both axial and circumferential directions. Finally, as the cable passes through the powder coating channel of the powder coating pipe 18, multiple brushes 20 apply powder to the surface of the cable's insulation layer to protect it.
