The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples.

[0025] The film forming device is used as a moisture-proof measure after the semi-conductive buffer water-blocking tape in the high-voltage power cable is wrapped and formed. It can effectively protect the semi-conductive buffer water-blocking tape from affecting the performance of the cable product due to moisture absorption during the production process.

[0026] Combine the following Figure 1-Figure 3 The film forming apparatus of the present invention is described.

[0027] The film forming device provided in the embodiment of the present invention includes: a support seat 10 , a reel-unwinding member 20 , a first position-limiting assembly 30 , a second position-limiting assembly 40 and a forming assembly 50 .

[0028] The support seat 10 is used to support the unwinding member 20, the first limiting assembly 30, the second limiting assembly 40 and the forming assembly 50. The support seat 10 is a liftable support seat, and the user can make a preliminary adjustment to the height of the film forming device by adjusting the height of the support seat 10. In one embodiment, the top surface of the support seat 10 can adjust its height through a lifting member 11. The lifting member 11 can be a worm gear. Specifically, one end of the worm is connected to the top of the support seat 10 to ensure that it can move in the vertical direction. The turbine is installed on the side of the worm to rotate and drive the worm. A hand wheel 12 is provided on the turbine, and the hand wheel 12 is rotated clockwise or counterclockwise to drive the worm to move up or down, thereby raising or lowering the support seat 10. After the support seat 10 reaches the desired height, a fixed locking device can be used to fix the worm gear to prevent the worm from moving due to its own weight or other external forces. In the embodiment of the present invention, the lifting and lowering of the support seat 10 can also be controlled by other lifting mechanisms, which will not be described in detail.

[0029] The unwinding member 20 is disposed at one end of the support seat 10 in the length direction, and is located above the top surface of the support seat 10, or is spaced apart from the support seat 10 in the length direction (e.g. Figure 1 As shown), it is convenient for the film tube to be sleeved on the unwinding member 20 and to rotate under the action of external force, thereby providing a continuous film for the cable to be wound. In order to achieve rapid fixation, the unwinding member 20 adopts an air-expanding shaft structure. Specifically, a ruler is attached to the air-expanding shaft, which can locate the center position of film tubes of different specifications, solves the problem of slipping during unwinding caused by different inner diameters of the film tube, and ensures the stability of the film during the unwinding process. When the film tube is placed on the air-expanding shaft, the air source is used to inflate the air inside the air-expanding shaft, so that the inner diameter of the air-expanding shaft is expanded, thereby tightly fixing the inner wall of the film tube, without the need for additional clamps or screws, greatly simplifying the operation steps. When the film tube needs to be replaced, it is only necessary to release the air pressure inside the air-expanding shaft to restore its inner diameter to its original state, and the film inner tube can be easily removed to achieve rapid replacement. The use of the air-expanding shaft not only improves the efficiency of fixing the film inner tube, but also reduces the film damage caused by improper fixation, and also solves the problem of the film tube not being clamped tightly and the center position being offset, thereby improving the continuity and stability of the production line. At the same time, due to the strong versatility of the air expansion shaft, it is suitable for film cylinders of various specifications, has low requirements for film cylinders, and improves the adaptability of the equipment.

[0030] The first limit assembly 30 and the second limit assembly 40 are arranged at both ends of the support seat 10 along the first direction, and are used to accurately limit the position of the cable to ensure the stability of the cable during production and processing. The first direction is consistent with the length direction of the support seat 10, and the cable can move along the first direction under the action of external force. Furthermore, in order to adapt to production lines of different heights, the first limit assembly 30 and the second limit assembly 40 in the embodiment of the present invention can be adjusted along the height direction of the support seat 10, so that the same set of equipment can meet the production requirements of different heights without replacing or reconfiguring new limit assemblies.

[0031] In one embodiment, the first limit assembly 30 is fixed to one end of the support seat 10 by a first fixing member, and the first limit assembly 30 can be moved up and down along the height direction of the first fixing member, such as by adjusting bolts, slide rails or other mechanical connectors. Similarly, the second limit assembly 40 can also be fixed to the other end of the support seat 10 by a second fixing member, and the second fixing member is also designed to be adjustable, and the second limit assembly 40 can be moved up and down along the height direction of the second fixing member, ensuring that the cable is limited consistently at both ends, further improving the accuracy of cable positioning.

[0032] The forming assembly 50 is disposed on the support seat 10, between the first stop assembly 30 and the second stop assembly 40. After the cable passes around the unwinding member 20, the film adheres to the upper surface of the cable to form a film-wound member and enters the forming area. Under the action of an external force, the film-wound member moves along a first direction, and the external force here can be provided by a conveying device, such as a conveyor belt, a roller, etc. The movement of the film-wound member is continuous and stable, ensuring that the film will not be displaced or damaged after being adhered to the cable.

[0033] The main function of the molding assembly 50 is to press the film adhered to the upper surface of the cable so that it is formed under the cable. The molding assembly 50 can be composed of one or more pairs of pressure wheels, clamps, molds or other molding tools, which can be adjusted according to the shape and size of the cable to ensure that the film can fit accurately under the cable. When the film-wrapped part moves under the molding assembly 50, the molding assembly 50 starts to work, and the pressure wheels or clamps apply uniform pressure to the film to make it close to the lower surface of the cable. The whole process can be continuous or step-by-step, depending on the configuration of the production line and the requirements of the cable.

[0034] The film forming device provided in the embodiment of the present invention ensures that the cable is always located in the center position during the entire process by sequentially arranging the unwinding member 20, the first limiting assembly 30, the forming assembly 50 and the second limiting assembly 40 along the first direction, thereby improving the forming accuracy; the height of the first limiting assembly 30 and the second limiting assembly 40 are adjustable to meet the production requirements of different heights, thereby 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 improving production efficiency.

[0035] The first limiting assembly 30 and the second limiting assembly 40 in the embodiment of the present invention both include a first bracket 41, a second bracket 42, an upper roller 43, a lower roller 44, a first vertical roller 45 and a second vertical roller 46. Figure 1 and Figure 3As shown, the first bracket 41 and the second bracket 42 are arranged on the support seat 10 at intervals along the second direction, and the second direction is perpendicular to the first direction, that is, the second direction is perpendicular to the moving direction of the cable. One end of the upper roller 43 is connected to the first bracket 41, and the other end of the upper roller 43 is connected to the second bracket 42, so that the upper roller 43 is stably located between the first bracket 41 and the second bracket 42. Similarly, one end of the lower roller 44 is connected to the first bracket 41, one end of the lower roller 44 is connected to the first bracket 41, and the other end of the lower roller 44 is connected to the second bracket 42, and the lower roller 44 is parallel to the lower side of the upper roller 43. The cable with the film adhered is located between the upper roller 43 and the lower roller 44, and the parallel configuration 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. The present invention can adjust the center height of the film forming device according to the diameter of the produced cable, which is used to correct the walking path of the cable, so that the center height of the film forming device and the production line is on the same horizontal line with the wrapping device, the traction device and other equipment, and the bending deformation of the cable is minimized.

[0036] Furthermore, both the upper roller 43 and the lower roller 44 can move along the height direction of the first bracket 41 and the second bracket 42. In one embodiment, the first bracket 41 is provided with a first slide rail, and the second bracket 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, so that the upper roller 43 and the lower roller 44 can be quickly adjusted without disassembly. Figure 1 As shown, the first bracket 41 is provided with a first through hole, and the first through hole extends along the height direction of the first bracket 41. The second bracket 42 is provided with a second through hole, and the second through hole extends along the height direction of the second bracket 42, so that the two ends of the rotating shaft of the upper roller 43 can be inserted and fixed. One end of the rotating shaft of the upper roller 43 is inserted in the first through hole, and the other end of the upper roller 43 is inserted in the second through hole. Both ends of the rotating shaft of the upper roller 43 are fixed by fasteners, such as the fasteners are fixed bolts, and the two fixed bolts are respectively threadedly connected with the rotating shaft and are arranged on both sides of the first bracket 41. The upper roller 43 can be fixed by screwing one of the fixed bolts, and it is screwed in the opposite direction when adjustment is required. The setting form of the lower roller 44 can be the same as that of the upper roller 43, which will not be repeated here, to ensure the synchronous adjustment and stability of the upper roller 43 and the lower roller 44.

[0037] Under the action of an external force, such as a conveyor belt or a thrust device, the cable with the film adhered thereto can move in a first direction toward the direction of the forming assembly 50. In this process, both the upper roller 43 and the lower roller 44 can rotate on their own to reduce friction on the cable and the film, prevent damage, and ensure that the cable with the film adhered thereto passes smoothly. It should be noted that the self-rotation function of the upper roller 43 and the lower roller 44 is achieved through bearings, which enables the film and the cable to move smoothly when passing through while maintaining uniform adhesion of the film. In addition, the material and surface 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.

[0038] The first vertical roller 45 and the second vertical roller 46 are arranged on the support seat 10 at intervals along the second direction, and are located on the side of the upper roller 43 close to the unwinding member 20, or on the side 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, which limits the position of the cable with the film adhered in the second direction so that it is always located in the center. Under the action of external force, it moves toward the direction of the second limit assembly 40. In this process, the first vertical roller 45 and the second vertical roller 46 can rotate to reduce the friction between the cable and the film, prevent damage, and ensure that the cable with the film adhered passes smoothly. It should be noted that the self-rotation function of the first vertical roller 45 and the second vertical roller 46 is realized by bearings, which enables 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.

[0039] Furthermore, the first vertical roller 45 and the second vertical roller 46 can move on the support seat 10 along the second direction to meet the production requirements of different center positions. In one embodiment, a slide rail is provided on the support seat 10, and the first vertical roller 45 and the second vertical roller 46 are both 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 the locking structure to ensure the stability of the position. The first vertical roller 45 and the second vertical roller 46 can be adjusted simultaneously or separately.

[0040] In one embodiment, a mounting plate is provided on the support seat 10, and a groove is provided on the mounting plate, the groove is extended along the second direction, a threaded rod is installed in the groove, and the bottoms of the first vertical roller 45 and the second vertical roller 46 are provided with a connecting portion, which is threadedly connected to the threaded rod, and the position of the first vertical roller 45 and the second vertical roller 46 on the threaded rod is adjusted by rotating the threaded rod. It should be noted that the relative position of the first vertical roller 45 and the second vertical roller 46 can be set in advance, and both can move at the same time, and the position is guaranteed to remain unchanged.

[0041] The first limit assembly 30 and the second limit assembly 40 in the embodiment of the present invention both adopt a mechanical structure, which can automatically follow the speed of the production line under the action of external force, thereby realizing an efficient and stable production process and greatly improving production efficiency and product quality.

[0042] The molding components 50 in the embodiment of the present invention may be multiple, such as 2, 3, 5, 8, etc. The multiple molding components 50 are arranged on the support seat 10 at intervals along the first direction. Figure 1 and Figure 2 As shown, there are four molding assemblies 50, of which two molding assemblies 50 near the first stop assembly 30 are used for pre-molding, and the molding angle is large. The two molding assemblies 50 near the second stop assembly 40 can be used for precise molding. It should be noted that the molding angles of the multiple molding assemblies 50 can be the same or different.

[0043] The molding assembly 50 is used to make the cable and the film fit together during the molding process. Figure 1 As shown, the forming assembly 50 includes a first guide roller 51, a second guide roller 52, a first fixed frame 53 and a second fixed frame 54. The first frame and the second frame are arranged at intervals on the support seat 10 along the second direction, providing a stable support structure for the forming assembly 50. The first guide roller 51 is connected to the first fixed frame 53, and the second guide roller 52 is connected to the second fixed frame 54. The first fixed 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 the first guide roller 51 can also rotate around the second rotating shaft to adjust the angle of the first guide roller 51. The second guide roller 52 also has a first rotating shaft and a second rotating shaft, and the second guide roller 52 can rotate around the first rotating shaft or the second rotating shaft to adjust the angle of the second guide roller 52. The first guide roller 51 and the second guide roller 52 match to guide the film on the upper surface of the cable to the bottom of the cable and complete the forming. This structure can adjust the forming angles of the first guide roller 51 and the second guide roller 52 according to different cables, without replacing the entire film forming device, thereby improving the versatility and ease of operation of the device. The positions of the first guide roller 51 and the second guide roller 52 are not specifically limited, for example, the first guide roller 51 and the second guide roller 52 are arranged correspondingly or staggered. The first guide roller 51 and the second guide roller 52 can rotate by themselves, which is achieved by bearings. Under the action of external force, the cable with the film attached can move smoothly when passing through.

[0044] Furthermore, the first guide roller 51 can move along the height direction of the first fixed frame 53, and the second guide roller 52 can move along the height direction of the second fixed frame 54.

[0045] Furthermore, the first guide roller 51 can move on the first fixing frame 53 along the first direction 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 1 As shown, there are two third through holes. The plurality of third through holes are arranged at intervals along the first direction.
