Description

Technical Field

[0001] This invention relates to the field of winding machine technology, and more particularly to a film forming apparatus. Background Technology

[0002] In the production process of high-voltage land cables, moisture-proofing measures for the semi-conductive buffer water-blocking tape are crucial, directly affecting the overall quality and long-term operational stability of the cable. Currently, this is typically achieved using longitudinal wrapping molds.

[0003] Longitudinal wrapping mold forming method has relatively low equipment investment costs and can achieve the function of film wrapping. However, the edge treatment of longitudinal wrapping molds is often not refined enough, with problems such as burrs and sharp edges. These defects can easily scratch the cable surface during wrapping, thus causing potential quality problems. When it is necessary to change the cable specification, the longitudinal wrapping mold needs to be replaced accordingly, and the forming height of the longitudinal wrapping device needs to be adjusted. This makes the mold less versatile and increases the time and cost of production preparation. Summary of the Invention

[0028] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0029] The film forming device is used for moisture protection measures after the semi-conductive buffer water-blocking tape is wrapped and formed in high-voltage power cables. It can effectively protect the performance of cable products from the impact of moisture absorption on the semi-conductive buffer water-blocking tape during the production process.

[0030] The following is combined Figures 1-3 The thin film forming apparatus of the present invention is described.

[0031] The film forming apparatus provided in this embodiment of the invention includes: a support base 10, an unwinding component 20, a first limiting component 30, a second limiting component 40, and a forming component 50.

[0032] The support base 10 supports the unwinding component 20, the first limiting component 30, the second limiting component 40, and the forming component 50. The support base 10 is a height-adjustable support base, allowing the user to initially adjust the height of the film forming device by adjusting the height of the support base 10. In one embodiment, the top surface of the support base 10 can be adjusted in height via a lifting component 11. The lifting component 11 can be a worm gear. Specifically, one end of the worm is connected to the top of the support base 10, ensuring it can move vertically. A turbine is mounted on the side of the worm, causing it to rotate and drive the worm. A handwheel 12 is provided on the turbine; rotating the handwheel 12 clockwise or counterclockwise drives the worm to move upward or downward, thereby raising or lowering the support base 10. After the support base 10 reaches the desired height, a locking device can be used to fix the worm gear, preventing the worm from moving due to its own weight or other external forces. In this embodiment of the invention, the raising and lowering of the support base 10 can also be controlled by other lifting mechanisms, which are not specifically described.

[0033] The unwinding component 20 is located at one end of the support base 10 along its length, above the top surface of the support base 10, or at a distance from the support base 10 along its length (e.g., ...). Figure 1 As shown in the diagram, the film tube is conveniently fitted onto the unwinding component 20 and can rotate under external force, thus providing a continuous film for the cable to be wound. For quick fixation, the unwinding component 20 adopts an air-expansion shaft structure. Specifically, a scale is attached to the air-expansion shaft to locate the center position of film tubes of different specifications, solving the slippage problem caused by varying inner diameters of the film tubes during unwinding and ensuring the stability of the film during the unwinding process. When the film tube is placed on the air-expansion shaft, air is injected into the shaft through an air source, expanding the inner diameter of the shaft and tightly fixing it to the inner wall of the film tube without the need for additional clamps or screws, greatly simplifying the operation. When the film tube needs to be replaced, simply release the air pressure inside the air-expansion shaft to restore its original inner diameter, and the film tube can be easily removed for quick replacement. The use of the air-expansion shaft not only improves the efficiency of fixing the film tube but also reduces film damage caused by improper fixing, and solves the problems of loose film tube clamping and center position misalignment, improving the continuity and stability of the production line. Meanwhile, due to the versatility of the air shaft, it is applicable to various specifications of diaphragm tubes, has low requirements for diaphragm tubes, and improves the adaptability of the equipment.

[0034] The first limiting component 30 and the second limiting component 40 are respectively disposed at both ends of the support base 10 along a first direction to precisely limit the position of the cable and ensure the stability of the cable during production and processing. The first direction is consistent with the length direction of the support base 10, allowing the cable to move along this direction under external force. Furthermore, to adapt to production lines of different heights, the first limiting component 30 and the second limiting component 40 in this embodiment can be adjusted along the height direction of the support base 10, enabling the same equipment to meet production needs at different heights without requiring replacement or reconfiguration of new limiting components.

[0035] In one embodiment, the first limiting component 30 is fixed to one end of the support base 10 by a first fixing member. The first limiting component 30 can move up and down along the height direction of the first fixing member, such as by adjusting bolts, slide rails, or other mechanical connecting parts. Similarly, the second limiting component 40 can also be fixed to the other end of the support base 10 by a second fixing member. The second fixing member is also designed to be adjustable, and the second limiting component 40 can move up and down along the height direction of the second fixing member, ensuring that the cable is consistently limited at both ends and further improving the accuracy of cable positioning.

[0036] The forming component 50 is mounted on the support base 10, located between the first limiting component 30 and the second limiting component 40. After the cable passes around the unwinding component 20, the film adheres to the upper surface of the cable, forming a film-wound component, which then enters the forming area. Under the action of an external force, the film-wound component moves along a first direction. This external force can be provided by a conveying device, such as a conveyor belt or rollers. The movement of the film-wound component is continuous and smooth, ensuring that the film does not shift or break after adhering to the cable.

[0037] The primary function of the forming assembly 50 is to press the film adhered to the upper surface of the cable, shaping it beneath the cable. The forming assembly 50 may consist of one or more pairs of pressure rollers, clamps, molds, or other forming tools, which can be adjusted according to the shape and size of the cable to ensure the film is precisely adhered beneath it. When the film-wrapping component moves beneath the forming assembly 50, the forming assembly 50 begins operation, with the pressure rollers or clamps applying uniform pressure to the film, ensuring it adheres tightly to the lower surface of the cable. The entire process can be continuous or step-by-step, depending on the production line configuration and the cable requirements.

[0038] The film forming apparatus provided in this embodiment of the invention ensures that the cable remains in the center position throughout the entire process by sequentially arranging the unwinding component 20, the first limiting component 30, the forming component 50, and the second limiting component 40 along the first direction, thereby improving the forming accuracy. The heights of the first limiting component 30 and the second limiting component 40 are adjustable to adapt to different production height requirements, enhancing the versatility and adaptability of the equipment. The cable can automatically follow the production speed, reducing manual intervention, improving the automation level of the production line, and increasing production efficiency.

[0039] In this embodiment of the invention, both the first limiting component 30 and the second limiting component 40 include a first support 41, a second support 42, an upper roller 43, a lower roller 44, a first vertical roller 45, and a second vertical roller 46. For example... Figure 1 and Figure 3 As shown, the first support 41 and the second support 42 are spaced apart on the support base 10 along a second direction, which is perpendicular to the first direction, i.e., the second direction is perpendicular to the direction of cable movement. One end of the upper roller 43 is connected to the first support 41, and the other end of the upper roller 43 is connected to the second support 42, thereby stabilizing the upper roller 43 between the first support 41 and the second support 42. Similarly, one end of the lower roller 44 is connected to the first support 41, and the other end of the lower roller 44 is connected to the second support 42. The lower roller 44 is parallel to and below the upper roller 43. The cable with the film adhered is located between the upper roller 43 and the lower roller 44. The parallel arrangement of the upper roller 43 and the lower roller 44 can limit the position of the cable with the film adhered in the height direction. This invention can adjust the center height of the film forming device according to the diameter of the produced cable to correct the cable's travel path, so that the center height of the film forming device and the production line is on the same horizontal line as the wrapping device, traction device, and other equipment, minimizing the bending deformation of the cable.

[0040] Furthermore, both the upper roller 43 and the lower roller 44 can move along the height direction of the first support 41 and the second support 42. In one embodiment, the first support 41 is provided with a first slide rail, and the second support 42 is provided with a second slide rail. One end of the upper roller 43 is slidably connected to the first slide rail, and the other end of the upper roller 43 is slidably connected to the second slide rail. One end of the lower roller 44 is slidably connected to the first slide rail, and the other end of the lower roller 44 is slidably connected to the second slide rail, allowing the upper roller 43 and the lower roller 44 to be quickly adjusted without disassembly. Figure 1As shown, the first bracket 41 has a first through hole extending along the height direction of the first bracket 41, and the second bracket 42 has a second through hole extending along the height direction of the second bracket 42, so that both ends of the upper roller 43 shaft can be inserted and fixed. One end of the upper roller 43 shaft is inserted into the first through hole, and the other end of the upper roller 43 is inserted into the second through hole. Both ends of the upper roller 43 shaft are fixed by fasteners, such as fixing bolts. The two fixing bolts are threadedly connected to the shaft and are located on both sides of the first bracket 41. The upper roller 43 can be fixed by tightening one of the fixing bolts, and the bolts are tightened in the opposite direction when adjustment is needed. The lower roller 44 can be set in the same way as the upper roller 43, which will not be described in detail here, ensuring the synchronous adjustment and stability of the upper roller 43 and the lower roller 44.

[0041] Under the action of an external force, such as a conveyor belt or a thrust device, the cable with the film adhered to it can move in the first direction toward the forming assembly 50. During this process, both the upper roller 43 and the lower roller 44 can rotate to reduce friction on the cable and film, prevent damage, and ensure the smooth passage of the cable with the film adhered to it. It should be noted that the rotation function of the upper roller 43 and the lower roller 44 is achieved through bearings, which allows the film and cable to move smoothly during passage while maintaining uniform film adhesion. Furthermore, the materials and surfaces of the upper roller 43 and the lower roller 44 have sufficient wear resistance and smoothness, thereby extending the service life of the equipment and ensuring the quality of the cable.

[0042] The first vertical roller 45 and the second vertical roller 46 are spaced apart on the support base 10 along the second direction, located on the side of the upper roller 43 closer to the unwinding member 20 or away from the unwinding member 20. The cable with the film adhered is located between the first vertical roller 45 and the second vertical roller 46, restricting the position of the cable with the film adhered in the second direction and keeping it always in the center position. Under the action of external force, it moves towards the second limiting component 40. During this process, both the first vertical roller 45 and the second vertical roller 46 can rotate to reduce friction on the cable and film, prevent damage, and ensure that the cable with the film adhered passes smoothly. It should be noted that the rotation function of the first vertical roller 45 and the second vertical roller 46 is achieved by bearings, which allows the cable to move smoothly when passing through while maintaining uniform adhesion of the film. In addition, the surfaces of the first vertical roller 45 and the second vertical roller 46 have sufficient wear resistance and smoothness, thereby extending the service life of the equipment and ensuring the quality of the cable.

[0043] Furthermore, the first vertical roller 45 and the second vertical roller 46 can move along a second direction on the support base 10 to adapt to production needs at different center positions. In one embodiment, the support base 10 is provided with a slide rail, and both the first vertical roller 45 and the second vertical roller 46 are slidably connected to the slide rail. It should be noted that when the first vertical roller 45 and the second vertical roller 46 move to the target position, they can be fixed and locked by a locking structure to ensure positional stability. The first vertical roller 45 and the second vertical roller 46 can be adjusted simultaneously or individually.

[0044] In one embodiment, the support base 10 is provided with a mounting plate, and the mounting plate has a groove extending along a second direction. A threaded rod is installed in the groove. The bottoms of the first vertical roller 45 and the second vertical roller 46 are both provided with connecting parts, which are threadedly connected to the threaded rod. The positions of the first vertical roller 45 and the second vertical roller 46 on the threaded rod can be adjusted by rotating the threaded rod. It should be noted that the relative positions of the first vertical roller 45 and the second vertical roller 46 can be preset, and both can move simultaneously while maintaining their positions.

[0045] In this embodiment of the invention, both the first limiting component 30 and the second limiting component 40 adopt mechanical structures, which can automatically follow the speed of the production line under the action of external force, realizing an efficient and stable production process and greatly improving production efficiency and product quality.

[0046] In this embodiment of the invention, there can be multiple molding components 50, such as 2, 3, 5, or 8. Multiple molding components 50 are spaced apart on the support base 10 along a first direction. For example... Figure 1 and Figure 2 As shown, there are four molding components 50. The two molding components 50 closest to the first limiting component 30 are used for pre-forming with a large molding angle. The two molding components 50 closest to the second limiting component 40 are used for precise molding. It should be noted that the molding angles of the multiple molding components 50 can be the same or different.

[0047] The molding component 50 is used to bond the cable to the film during the molding process. For example... Figure 1As shown, the molding assembly 50 includes a first guide roller 51, a second guide roller 52, a first fixing frame 53, and a second fixing frame 54. The first and second fixing frames are spaced apart along a second direction on the support base 10, providing a stable support structure for the molding assembly 50. The first guide roller 51 is connected to the first fixing frame 53, and the second guide roller 52 is connected to the second fixing frame 54. The first fixing frame 53 has a first rotating shaft and a second rotating shaft; the first rotating shaft is parallel to the first direction, and the second rotating shaft is parallel to the second direction. The first guide roller 51 can rotate around the first rotating shaft and can also rotate around the second rotating shaft to adjust its angle. The second guide roller 52 also has a first rotating shaft and a second rotating shaft; it can rotate around either the first or the second rotating shaft to adjust its angle. The first guide roller 51 and the second guide roller 52 are matched to guide the film on the upper surface of the cable to below the cable, completing the molding process. This structure allows adjustment of the forming angles of the first guide roller 51 and the second guide roller 52 according to different cables, eliminating the need to replace the entire film forming device and improving the equipment's versatility and ease of operation. The positions of the first guide roller 51 and the second guide roller 52 are not specifically limited; for example, they can be arranged correspondingly or staggered. The first guide roller 51 and the second guide roller 52 can rotate via bearings, allowing the cable with the film adhered to it to move smoothly when passing under external force.

[0048] Furthermore, the first guide roller 51 is movable along the height direction of the first fixed frame 53, and the second guide roller 52 is movable along the height direction of the second fixed frame 54. In one embodiment, the first fixed frame 53 is provided with a third slide rail, which extends along the height direction of the first fixed frame 53. The first guide roller 51 is slidably connected to the third slide rail. The second fixed frame 54 is provided with a fourth slide rail, which extends along the height direction of the second fixed frame 54. The second guide roller 52 is slidably connected to the fourth slide rail. This structure allows for quick adjustment without disassembly. Figure 1 As shown, the first fixing frame 53 has a three-way hole, and the third through hole extends along the height direction of the first fixing frame 53. The first guide roller 51 is inserted into the third through hole and can move up and down along the third through hole, and is fixed by fasteners. The second fixing frame 54 has a fourth through hole, and the fourth through hole extends along the height direction of the second fixing frame 54. The second guide roller 52 can move up and down along the fourth through hole so that the second guide roller 52 can be inserted into the fourth through hole and fixed by fasteners.

[0049] Furthermore, the first guide roller 51 can move along the first direction on the first fixed frame 53 to adjust the position of the first guide roller 51 in the first direction. In one embodiment, there are multiple third through holes, such as 2, 3, 4, 6, etc. Figure 1As shown, there are two third through holes. Multiple third through holes are spaced apart along the first direction. In actual use, the first vertical roller 45 can be fixed in the corresponding third through hole as needed. In another embodiment, a slide rail can also be provided along the first direction in the direction of the first fixed frame 53, and the first guide roller 51 moves along the extending direction of the slide rail.

[0050] The second guide roller 52 can move along the first direction on the second fixed frame 54 to adjust its position. In one embodiment, there are multiple fourth through holes, such as 2, 4, 6, etc. Figure 1 As shown, there are two fourth through holes. Multiple fourth through holes are spaced apart along the first direction. In actual use, the second vertical roller 46 can be fixed in the corresponding fourth through hole as needed. It should be noted that the number of fourth through holes can be the same as or different from the number of third through holes. The positions of the fourth through holes can correspond to the positions of the third through holes or be staggered. In another embodiment, a slide rail can also be provided along the first direction in the direction of the second fixed frame 54, and the second guide roller 52 moves along the extension direction of the slide rail.

[0051] Furthermore, both the first fixed frame 53 and the second fixed frame 54 can move back and forth on the support base 10 along the first direction to adjust the position of the first guide roller 51 and the second guide roller 52.

[0052] In this embodiment of the invention, both the first fixing frame 53 and the second fixing frame 54 can move back and forth on the support base 10 along the second direction to adjust the positions of the first guide roller 51 and the second guide roller 52. Figure 2 As shown, a slide rail is provided on the support base 10, and the slide rail extends along the second direction. The first fixing bracket 53 and the second fixing bracket 54 are slidably connected to the slide rail.

[0053] In one specific embodiment, the molding assembly 50 further includes a first upright plate 55, a second upright plate 56, and a sliding plate 57. The first upright plate 55 and the second upright plate 56 are respectively disposed on both sides of the support base 10 along a second direction. One end of the sliding plate 57 is connected to the first upright plate 55, and the other end of the sliding plate 57 is connected to the second upright plate 56. The sliding plate 57 can move along the first upright plate 55 and the second upright plate 56 along the first direction, such as by providing a slide rail. In one embodiment, the first upright plate 55 and the second upright plate 56 have multiple fixed positions, such as 3, 4, 7, etc. Figure 1 As shown, both the first upright plate 55 and the second upright plate 56 are provided with two fixing holes.

[0054] The first fixing bracket 53 and the second fixing bracket 54 are spaced apart on the slide plate along the second direction and can move along the extension direction (second direction) of the slide plate 57. In one embodiment, the slide plate 57 is provided with a slide rail, and the first fixing bracket 53 and the second fixing bracket 54 are slidably connected to the slide plate 57 respectively.

[0055] Furthermore, the slide plate 57 can move along the height direction of the first upright plate 55 and the second upright plate 56 to initially adjust the height of the first guide roller 51 and the second guide roller 52. After adjusting to the target position, precise adjustment is achieved by controlling the first guide roller 51 to move along the height direction of the first fixed frame 53 and the second guide roller 52 to move along the height direction of the second fixed frame 54.

[0056] In one embodiment, a fifth through hole is provided on the first upright plate 55, extending along the height direction of the first upright plate 55. A sixth through hole is provided on the second upright plate 56, extending along the height direction of the second upright plate 56. The slide plate 57 can slide along the fifth and sixth through holes. After sliding to the target position, it is fixed by fasteners. There can be multiple fifth through holes, which are arranged along a first direction on the first upright plate 55. Multiple sixth through holes are arranged along the first direction on the second upright plate 56. The slide plate 57 can be connected through any of the fifth and sixth through holes, thereby adjusting the position of the slide plate 57, i.e., the initial adjustment of the first guide roller 51 and the second guide roller 52. After completion, by controlling the movement of the first guide roller 51 on the first fixed frame 53 and the movement of the second guide roller 52 on the second fixed frame 54, a precise adjustment is achieved.

[0057] To prevent cable sagging, the film forming apparatus provided in this embodiment of the invention further includes a support component 60 for supporting the cable. In one embodiment, the support component 60 is located between the first limiting component 30 and the second limiting component 40, providing good support. Figure 1 and Figure 3 As shown, there are four forming components 50, which are symmetrically arranged on both sides of the support component 60 to support the cable and ensure its forming effect.

[0058] Specifically, the support assembly 60 includes a support roller 61, a first support frame 62, and a second support frame 63. The first support frame 62 and the second support frame 63 are spaced apart along a second direction on the support base 10, located between the first limiting assembly 30 and the second limiting assembly 40. One end of the support roller 61 is connected to the first support frame 62, and the other end of the support roller 61 is connected to the second support frame 63. The support roller 61 is collinear with the lower roller 44 and is used to support the cable, prevent it from sagging, and improve the forming effect of the forming assembly 50. It should be noted that the support roller 61 can also rotate, and under the action of external force, the cable can move smoothly along the first direction.

[0059] Furthermore, the support roller 61 can move along the height direction of the first support frame 62 and the second support frame 63 to adjust the height of the support roller 61, ensuring that the support roller 61 is always collinear with the lower roller 44, thus adapting to production lines with different height directions. In one embodiment, the first support frame 62 and the second support frame 63 are provided with slide rails arranged along the height direction. In another embodiment, the first support frame 62 and the second support frame 63 are provided with multiple limiting grooves along the height direction, and the two ends of the support roller 61 are engaged within the limiting grooves.

[0060] In this embodiment of the invention, there may be multiple support components 60, such as 2, 5, or 6. Multiple support components 60 are spaced apart on the support base 10 along a first direction.

[0061] In addition, all adjustable components in the embodiments of the present invention can be provided with scales or indicators to determine the adjustment position and improve the accuracy of adjustment.

[0062] In this embodiment of the invention, both ends of the roller can be sealed with bearing caps to prevent bearing oil from dripping onto the semiconducting resistance water tape of the cable; it can also prevent burrs on the roller edge from scratching the film and the semiconducting resistance water tape on the cable.

[0063] The structure in this embodiment of the invention is a purely mechanical structure. The mechanical structure is simple, without any drive mechanism, and is an energy-saving and environmentally friendly design. The forming speed is unaffected by the production line speed and can quickly follow the production line speed. Because this film forming device has no rotating or transmission mechanisms, it will not cause harm to operators. In this invention, the film is wound by the forming component 50, which is easy to disassemble before the next process, requiring no manual intervention and allowing for quick detachment. The film forming device has a simple structure, facilitating equipment maintenance and resulting in a low failure rate. Simple daily maintenance by operators is sufficient to meet maintenance requirements, eliminating the need for professional technicians.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
